Background

Feedlot cattle in North America are routinely fed subtherapeutic levels of antimicrobials to prevent disease and improve the efficiency of growth. This practice has been shown to promote antimicrobial resistance (AMR) in subpopulations of intestinal microflora including Escherichia coli. To date, studies of AMR in feedlot production settings have rarely employed selective isolation, therefore yielding too few AMR isolates to enable characterization of the emergence and nature of AMR in E. coli as an indicator bacterium. E. coli isolates (n = 531) were recovered from 140 cattle that were housed (10 animals/pen) in 14 pens and received no dietary antimicrobials (control - 5 pens, CON), or were intermittently administered subtherapeutic levels of chlortetracycline (5 pens-T), chlortetracycline + sulfamethazine (4 pens-TS), or virginiamycin (5 pens-V) for two separate periods over a 9-month feeding period. Phenotype and genotype of the isolates were determined by susceptibility testing and pulsed field gel electrophoresis and distribution of characterized isolates among housed cattle reported. It was hypothesized that the feeding of subtherapeutic antibiotics would increase the isolation of distinct genotypes of AMR E. coli from cattle.

Results

Overall, patterns of antimicrobial resistance expressed by E. coli isolates did not change among diet groups (CON vs. antibiotic treatments), however; isolates obtained on selective plates (i.e., MA,MT), exhibited multi-resistance to sulfamethoxazole and chloramphenicol more frequently when obtained from TS-fed steers than from other treatments. Antibiograms and PFGE patterns suggested that AMR E. coli were readily transferred among steers within pens. Most MT isolates possessed the tet(B) efflux gene (58.2, 53.5, 40.8, and 50.6% of isolates from CON, T, TS, and V steers, respectively) whereas among the MA (ampicillin-resistant) isolates, the tem1-like determinant was predominant (occurring in 50, 66.7, 80.3, and 100% of isolates from CON, T, TS, and V steers, respectively).

Conclusions

Factors other than, or in addition to subtherapeutic administration of antibiotics influence the establishment and transmission of AMR E. coli among feedlot cattle.

Objectives

Antibiotic resistance (ABR) particularly hits resource poor countries, and is fuelled by irrational antibiotic (AB) prescribing. We surveyed knowledge, attitudes and practices of AB prescribing among medical students and doctors in Kisangani, DR Congo.

Methods

Self-administered questionnaires.

Results

A total of 184 questionnaires were completed (response rate 94.4%). Knowledge about AB was low (mean score 4.9/8 points), as was the estimation of local resistance rates of S. Typhi and Klebsiella spp.(correct by 42.5% and 6.9% of respondents respectively). ABR was recognized as a problem though less in their own practice (67.4%) than nation- or worldwide (92.9% and 85.5%, p<.0001). Confidence in AB prescribing was high (88.6%) and students consulted more frequently colleagues than medical doctors when prescribing (25.4% versus 11.6%, p  = 0.19). Sources of AB prescribing included pharmaceutical companies (73.9%), antibiotic guidelines (66.3%), university courses (63.6%), internet-sites (45.7%) and WHO guidelines (26.6%). Only 30.4% and 16.3% respondents perceived AB procured through the central procurement and local pharmacies as of good quality. Local AB guidelines and courses about AB prescribing are welcomed (73.4% and 98.8% respectively).

Conclusions

This data shows the need for interventions that support rational AB prescribing.

The potential contribution nurses can make to the management of antimicrobials within an in-patient setting could impact on the development of antimicrobial resistance (AMR) and healthcare associated infections (HCAIs). Current initiatives promoting prudent antimicrobial prescribing and management have generally failed to include nurses, which subsequently limits the extent to which these strategies can improve patient outcomes. For antimicrobial stewardship (AS) programmes to be successful, a sustained and seamless level of monitoring and decision making in relation to antimicrobial therapy is needed. As nurses have the most consistent presence as patient carer, they are in the ideal position to provide this level of service. However, for nurses to truly impact on AMR and HCAIs through increasing their profile in AS, barriers and facilitators to adopting this enhanced role must be contextualised in the implementation of any initiative.

Background

Burden of death and disability resulting from lack of emergency medical system (EMS) and emergency care is very high in low and middle income countries (LMIC).

Aim

To study the knowledge, attitudes and practices of pre-hospital care and emergency services among health care providers of Lucknow

Setting and Design

Cross-sectional survey, 200 residents, 104 hospital consultants and 108 private practitioners

Material and Methods

A close ended, self administered questionnaire based on 5-point Likert scale with 30 items of knowledge, attitude and practice of pre-hospital and emergency care

Results

Median scores of knowledge (26/50), attitude (41/50) and practices (27/50) showed less than adequate knowledge and practices. However, a positive attitude was seen in all the 3 group of respondents i.e. resident doctors, hospital consultants and private practitioners.

Conclusion

Lucknow is the capital city of Indian largest state — Uttar Pradesh with over 100 years of established medical education. The results of the study in this town are applicable to most developed cities in India. Lack of adequate knowledge and practices in emergency medical system (EMS) at Lucknow represent a dismal situation and require continuing medical education in this area.

The purpose of this study was to examine the prevalence and patterns of antimicrobial resistance (AMR) in enteric bacteria obtained from Ontario sheep flocks, and associations between antimicrobial use (AMU) and AMR. Forty-nine sheep producers participated for a 1-year interval between 2006 and 2008. Two-hundred and eighty-three pooled fecal samples were collected from the flocks during initial and final visits. Up to 3 isolates of Salmonella spp. and generic E. coli per pooled fecal sample were tested for susceptibility to 15 antimicrobials. Resistance was infrequent among Salmonella (0%, n = 7 isolates) and low among E. coli (13.1%; n = 849) isolates. A small number of isolates were resistant to antimicrobials classified as being of very high importance to human health. Tetracycline resistance was most frequently observed (12.0%). Logistic regression was used to model potential AMU (qualitative and quantitative) risk factors for tetracycline resistance in generic E. coli from final visits. Qualitative analysis indicated that the use of injectable sulfonamides [including trimethoprim-sulfonamide combinations (TMS)] and tetracycline in the feed and water were significantly associated with tetracycline resistance (OR = 2.6, P = 0.01; and OR = 4.8, P ≤ 0.01, respectively). Quantitative analysis also indicated that TMS exposure rate was significantly associated with tetracycline resistance, which varied depending on the exposure rate. The exposure rate of tetracycline in the feed and water was only significant after the removal of one influential flock, warranting further research examining flocks with higher tetracycline exposure rates. Although the prevalence of AMR in participating flocks was relatively low, risk factors for resistance were identified.

Background

Several studies have assessed the epidemiology of HPV infection among MSM, but no qualitative studies have specifically assessed how HPV and genital warts (GW) affect South American men who have sex with men (MSM) and male-to-female transgendered women (TG). This study explored the knowledge, attitudes and experiences of Peruvian MSM and TG regarding HPV and GW.

Methods

We performed a qualitative study consisting of fifteen in-depth interviews and three focus groups carried out in Lima, Peru with diverse MSM and TG groups, including sex workers. Resulting data were analyzed by applying a systematic comparative and descriptive content analysis.

Results

While knowledge of HPV was limited, awareness of GW was common, particularly among TG persons and sex workers. Still, few participants recognized that GW are sexually transmitted, and many had problems differentiating between GW and other STI/anogenital conditions. Stigmatizing experiences were common during sexual encounters with people who had visible GW. Shame, emotional and physical troubles, and embarrassing sexual experiences were reported by individuals with GW. Search for treatment was mediated by peers, but stigma and apparent health services’ inability to deal with GW limited the access to effective medical care.

Conclusions

In Peru, public health interventions should strengthen services for HPV/GW management and increase accurate knowledge of the transmission, treatment, and sequelae of HPV/GW in MSM and TG populations.

Objectives

According to a large-scale international survey, Peru has one of the highest prevalences of asthma worldwide; however, data from this survey were limited to participants from urban Lima. The authors sought to characterise the epidemiology of asthma in Peru in two regions with disparate degrees of urbanisation. In this manuscript, the authors summarise the study design and implementation.

Design

A cross-sectional study.

Participants

Using census data of 13–15-year-old adolescents from two communities in Peru, the authors invited a random sample of participants in Lima (n=725) and all adolescents in Tumbes (n=716) to participate in our study.

Primary and secondary outcome measures

The authors asked participants to complete a questionnaire on asthma symptoms, environmental exposures and socio-demographics and to undergo spirometry before and after bronchodilator, skin allergy testing and exhaled nitric oxide testing. The authors obtained blood samples for haematocrit, total IgE levels, vitamin D levels and DNA in all participants and measured indoor particulate matter concentrations for 48 h in a random subset of 70–100 households at each site.

Results

Of 1851 eligible participants, 1441 (78%) were enrolled and 1159 (80% of enrolled) completed all physical tests. 1283 (89%) performed spirometry according to standard guidelines, of which 86% of prebronchodilator tests and 92% of postbronchodilator tests were acceptable and reproducible. 92% of allergy skin tests had an adequate negative control. The authors collected blood from 1146 participants (79%) and saliva samples from 148 participants (9%). Overall amounts of DNA obtained from blood or saliva were 25.8 μg, with a 260/280 ratio of 1.86.

Conclusions

This study will contribute to the characterisation of a variety of risk factors for asthma, including urbanisation, total IgE levels, vitamin D levels and candidate genes, in a resource-poor setting. The authors present data to support high quality of survey, allergic, spirometric and genetic data collected in our study.

Article summary

Article focus

We sought to characterise the epidemiology of asthma in Peru by studying two regions with disparate degrees of urbanisation.

We summarise the study design, implementation and standard operating procedures and provide quality control data for important outcome and exposure variables.

Key messages

We present data to support high quality of survey, allergic, spirometric and genetic data collected in our study.

Strengths and limitations of this study

This study will contribute to the characterisation of a variety of risk factors for asthma, including urbanisation, total IgE levels, vitamin D levels and candidate genes, in a resource-poor setting.

This study is cross-sectional and therefore does not track symptoms over time to directly determine causality. In addition, we did not collect stool samples to assess parasitic infections nor do we have information on respiratory infections in early childhood.

Objective

To describe rates of antimicrobial resistance (AMR) among Salmonella and Shigella isolates reported in five Canadian provinces, focusing on clinically important antimicrobials.

Methods

The authors retrospectively investigated AMR rates among 6219 Salmonella and 1673 Shigella isolates submitted to provincial public health laboratories in Alberta, Newfoundland and Labrador, Ontario, Prince Edward Island and Saskatchewan from 1997 to 2000; these isolates were estimated to represent 41% of Salmonella cases and 72% of Shigella cases reported by the study provinces.

Results

Among Salmonella isolates, 27% (1704 of 6215) were resistant to ampicillin, 2.2% (135 of 6122) to trimethoprim/ sulfamethoxazole, 1.5% (14 of 938) to nalidixic acid, 1.2% (one of 84) to lomafloxacin and 0.08% (five of 6163) to ciprofloxacin. Among Shigella isolates, 70% (1144 of 1643) were resistant to trimethoprim/sulfamethoxazole, 65% (1079 of 1672) to ampicillin, 3.1% (eight of 262) to nalidixic acid, 0.49% (eight of 1636) to ciprofloxacin, 0.14% (one of 700) to ceftriaxone and 0.08% (one of 1292) to ceftazidime.

Conclusions

Higher rates of resistance to clinically important antimicrobials (including ciprofloxacin) were observed among both Salmonella and Shigella isolates than has previously been reported. Current Canadian data on rates of AMR for these pathogens are required.

Background

Tobacco smoking is an important public health concern worldwide leading to both chronic disease and early death. In Latin America, smoking prevalence is estimated at approximately 30% and prior studies suggest that the prevalence in Peru is 22% to 38%. We sought to determine the prevalence of daily smoking in a poor peri-urban community in Lima, Peru.

Methods

We conducted a cross-sectional survey in a random sample of adults ≥40 years of age living in Pampas de San Juan de Miraflores, Lima, Peru. We asked participants to respond to a survey that included questions on sociodemographics, tobacco use and dependence.

Results

We enrolled 316 participants. Average monthly household income was ≤ 400 USD and nearly all homes had running water, sewage, and electricity. Most individuals had not completed high school. Smoking prevalence was 16% overall, yet daily smoking prevalence was 1.9%. Former daily smokers comprised 3.8% of current nonsmokers and 9.1% current occasional smokers. Average scores for the Fagerstrom Test for Nicotine Dependence for daily smokers and occasional smokers were 1.5 and 0, respectively.

Conclusions

Daily use of tobacco is uncommon among adults in peri-urban communities of Lima, Peru, unlike their counterparts in Lima and other Latin American capital cities. Tobacco dependence is also low. Hence, efforts aimed at primary prevention are of utmost importance in these communities. This study provides an accurate baseline using an internationally recognized assessment tool (Global Adult Tobacco Survey), allowing for accurate assessment of tobacco control interventions over time.

Objectives

To assess the prevalence of sexually transmitted infections (STIs), frequency of sexual risk behaviors, and relationship between knowledge of HIV infection status and sexual risk behavior among HIV-infected men who have sex with men (MSM) attending an STI clinic in Peru.

Methods

We recruited a convenience sample of 559 MSM from a municipal STI clinic in Lima, Peru. Participants completed a survey and provided blood for HIV, Syphilis, and HSV-2 antibody testing, and urine for gonorrhea and chlamydia nucleic acid testing.

Results

Among 124 HIV-infected MSM, 72.6% were aware of their HIV-infected status. Active syphilis (RPR≥1:8) was diagnosed in 21.0% of HIV-infected participants, HSV-2 in 79.8%, urethral gonorrhea in 1.6%, and chlamydia in 1.6%. Among 41 participants reporting insertive anal intercourse with their last sex partner, 34.2% did not use a condom. Of 86 participants reporting receptive anal intercourse, 25.6% did not use a condom. At least one episode of insertive unprotected anal intercourse (UAI) with an HIV-uninfected partner during the previous six months was reported by 33.6% (35/104) of participants, and receptive UAI with an HIV-uninfected partner by 44.6% (45/101). No difference in frequency of UAI, with HIV-uninfected or HIV-infected partners, was observed between men who knew their serostatus compared with those who were previously undiagnosed (all p-values >0.05).

Conclusions

HIV-infected MSM in Peru engaged in high-risk behaviors for spreading HIV and STIs. Knowledge of HIV-infected status was not associated with a decreased frequency of unprotected anal intercourse. Additional efforts to reduce risk behavior after the diagnosis of HIV infection are necessary.

Background

Antimicrobial resistance (AMR) in Neisseria gonorrhoeae is a major public health concern worldwide. In Vietnam, knowledge regarding N. gonorrhoeae prevalence and AMR is limited, and data concerning genetic characteristics of N. gonorrhoeae is totally lacking. Herein, we investigated the phenotypic AMR (previous, current and possible future treatment options), genetic resistance determinants for extended-spectrum cephalosporins (ESCs), and genotypic distribution of N. gonorrhoeae isolated in 2011 in Hanoi, Vietnam.

Methods

N. gonorrhoeae isolates from Hanoi, Vietnam isolated in 2011 (n = 108) were examined using antibiograms (Etest for 10 antimicrobials), Neisseria gonorrhoeae multi-antigen sequence typing (NG-MAST), and sequencing of ESC resistance determinants (penA, mtrR and penB).

Results

The levels of in vitro resistance were as follows: ciprofloxacin 98%, tetracycline 82%, penicillin G 48%, azithromycin 11%, ceftriaxone 5%, cefixime 1%, and spectinomycin 0%. The MICs of gentamicin (0.023-6 mg/L), ertapenem (0.002-0.125 mg/L) and solithromycin (<0.016-0.25 mg/L) were relatively low. No penA mosaic alleles were found, however, 78% of the isolates contained an alteration of amino acid A501 (A501V (44%) and A501T (34%)) in the encoded penicillin-binding protein 2. A single nucleotide (A) deletion in the inverted repeat of the promoter region of the mtrR gene and amino acid alterations in MtrR was observed in 91% and 94% of the isolates, respectively. penB resistance determinants were detected in 87% of the isolates. Seventy-five different NG-MAST STs were identified, of which 59 STs have not been previously described.

Conclusions

In Vietnam, the highly diversified gonococcal population displayed high in vitro resistance to antimicrobials previously recommended for gonorrhoea treatment (with exception of spectinomycin), but resistance also to the currently recommended ESCs were found. Nevertheless, the MICs of three potential future treatment options were low. It is essential to strengthen the diagnostics, case reporting, and epidemiologic surveillance of gonorrhoea in Vietnam. Furthermore, the surveillance of gonococcal AMR and gonorrhoea treatment failures is imperative to reinforce. Research regarding novel antimicrobial treatment strategies (e.g., combination therapy) and new antimicrobials is crucial for future treatment of gonorrhoea.

A primary care led NHS, driven by evidence based practice, needs to build on a firm foundation of research in primary care. As researchers are making increasing use of questionnaire surveys to assess general practitioners' views and attitudes, so response rates to questionnaire surveys among general practitioners are dropping. The reasons include lack of perceived relevance of the research and lack of information and feedback about it, and researchers need to be more aware of the realities of everyday practice. Approaches that might reverse this trend include monitoring all research activities going on in an area to ensure that practices are not overused, giving general practitioners incentives to participate, and improving the relevance of research and the quality of questionnaires.

Background

Spirometry is a cost-effective diagnostic tool for evaluation of lung function and for case-finding in a resource-limited setting. The acceptance of this test depends on the awareness of its indications and the ability to interpret the results. No studies have assessed the knowledge of spirometry among Nigerian doctors. The aim of this study was to evaluate the current knowledge, awareness and practice of spirometry among hospital-based Nigerian doctors.

Methods

We carried out a cross-sectional survey among 321 doctors working in Nigerian hospitals between March 2008 and June 2008. Information on knowledge, awareness, practice of and barriers to spirometry were obtained using a pre-tested, self-administered structured questionnaire and the data were then analysed.

Results

Of the 321 doctors that participated, 108 (33.6%) reported that they have good knowledge of spirometry. One hundred and ninety-five (60.7%) were aware of the importance of spirometry in aiding the diagnosis of respiratory diseases; 213(66.4%) were aware of the importance of spirometry in determining the severity of diseases. Medical school was the most common source of knowledge on spirometry (64.5%). Eighty-one (25.2%) doctors reported having a spirometer in their hospitals. Doctors having access to a spirometer used it more frequently for aiding the diagnosis of COPD (40.7% vs.27.5%) and for monitoring of asthma (18.5% vs.11.3%) than those without access to a spirometer. The doctors working in University Teaching Hospitals and Federal Medical Centres (FMC) (22.4% vs. 4.5%) and those having access to a spirometer (40.7 vs.11.3%) were very confident of interpreting spirometry results compared to those working in District and General Hospitals and without access to a spirometer. Irrespective of access to a spirometer or the type of hospital they were employed in, doctors reported that unavailability of a spirometer was the greatest barrier to its use (62.5%) followed by lack of awareness about its usefulness (17.2%).

Conclusion

The knowledge and practice of spirometry were poor among hospital-based Nigerian doctors because of unavailability of spirometers in most hospitals. These findings have implications for further evaluation, planning and management of patient care in respiratory disease. Spirometers should be made available in all hospitals, and the knowledge of spirometry should be improved among doctors.

Background

Evidence on the prevalence and determinants of burnout among military acute and critical care nursing personnel from developing countries is minimal, precluding the development of effective preventive measures for this high-risk occupational group. In this context, we aimed to examine the association between the dimensions of burnout and selected socio-demographic and occupational factors in military acute/critical care nursing personnel from Lima, Peru.

Methods and Findings

We conducted a cross-sectional study in 93 nurses/nurse assistants from the acute and critical care departments of a large, national reference, military hospital in Lima, Peru, using a socio-demographic/occupational questionnaire and a validated Spanish translation of the Maslach Burnout Inventory. Total scores for each of the burnout dimensions were calculated for each participant. Higher emotional exhaustion and depersonalisation scores, and lower personal achievement scores, implied a higher degree of burnout. We used linear regression to evaluate the association between each of the burnout dimensions and selected socio-demographic and occupational characteristics, after adjusting for potential confounders. The associations of the burnout dimensions were heterogeneous for the different socio-demographic and occupational factors. Higher emotional exhaustion scores were independently associated with having children (p<0.05) and inversely associated with the time working in the current department (p<0.05). Higher depersonalization scores were independently associated with being single compared with being divorced, separated or widowed (p<0.01), working in the emergency room/intensive care unit compared with the recovery room (p<0.01), and inversely associated with age (p<0.05). Finally, higher personal achievement scores were independently associated with having children (p<0.05).

Conclusion

Among Peruvian military acute and critical care nursing personnel, potential screening and preventive interventions should focus on younger/less experienced nurses/nurse assistants, who are single, have children, or work in the most acute critical care areas (e.g. the emergency room/intensive care unit).

Objective

To better understand physicians' views on factors of influence for the prescribing of antibiotics and on antibiotic resistance in the Berlin region, Germany.

Design

Qualitative study with focus groups.

Setting

Outpatient care and hospital care practice in the Berlin region, Germany.

Participants

7 General practitioners, two urologists, one paediatrician from outpatient care and eight internists, two paediatricians, two ear, nose and throat specialists and two urologists from hospital care.

Results

Physicians showed differential interest in topics related to antibiotic prescribing and antibiotic resistance. Outpatient care physicians were interested in topics around their own prescribing, such as being able to diagnose and prescribe precisely, and topics about patient demand and non-compliance. Hospital care physicians were interested in hygiene challenges, limited consult time and multi-resistant pathogens.

Conclusions

Physicians considered the development of resistance to be more in the domain of clinical treatment than that of the patient. Major challenges related to antibiotic resistance for this group of physicians are access to and clarity of treatment recommendations, implementation of hygienic measures, as well as increased outsourcing of laboratory services. Results raise questions about whether meeting physicians' expectations should be a focus when developing intervention that aims to influence antibiotic resistance in this and other areas of Germany.

Article summary

Article focus

Overuse of antibiotics across many specialities and in some of the most common diagnoses remains a driving force for antibiotic resistance.

While much attention has focused on limiting use and addressing clinical concerns like improving point-of-care diagnostic tests, prior literature has largely left out the consideration of socio-behavioural factors that influence physicians' decisions to prescribe antibiotics.

Focus group discussions were used to show physicians' views on factors that influence their prescribing of antibiotics and antibiotic resistance.

Key messages

Berlin area physicians are interested in receiving help to make informed decisions on the appropriate measures for mitigating patient discomfort and risk.

In this group, well-informed prescribing practice appears to be influenced by non-patient-oriented factors that are both structural (eg, overcrowding in hospitals) as well as non-structural in nature (eg, access to feedback from microbiologists or time allowed for patient consult).

Physicians desire intervention activities that address their own skills, like assessment of patient needs, time management for consult and navigation of pharmaceutical consulting.

Strengths and limitations of this study

Modern methodologies for focus group data analysis, including a comprehensive plan for ensuring validity in data-making and data reduction were used in the study.

Presented study methodology allows replication by other research groups.

The number of participating physicians was limited; however, they were recruited from diverse backgrounds with respect to age, sex, size of practice, care setting and number of years in practice.

Antimicrobial resistance (AMR) is an emerging animal welfare and public health issue linked to antimicrobial use (AMU) in livestock. This study was conducted in 2004 on 20 swine farms in Alberta and Saskatchewan. On-farm records and questionnaires were used to retrospectively describe the antimicrobial exposures of pigs through feed, water, and injection. Antimicrobial use in all production categories was described over 12 months. On-farm records and questionnaires provided sufficient data to describe antimicrobial exposure rates through feed and water. In contrast, on-farm records did not supply sufficient data to describe parenteral antimicrobial exposure rates. Records lacked data on the number of exposures per treatment, therefore parenteral AMU was described as an exposure incidence. Parenteral exposure records were often unavailable for pigs less than 22 kg, in which case questionnaires were used. The incidence of parenteral AMU was significantly higher in herds reporting exposure by questionnaire compared with existing records, suggesting that on-farm records did not reliably describe parenteral AMU. However, because antimicrobial exposures in feed and water were markedly more common than through injection, it was concluded that existing on-farm data would be a valuable resource for investigating AMU and AMR in pigs.

Streptococcus pneumoniae isolates were obtained from nasopharyngeal swabs taken from children living in a low socioeconomic area of Lima, Peru, to determine the rates of antimicrobial resistance and serotype distribution. A total of 146 nasopharyngeal isolates were collected from children from 3 to 38 months of age. Twenty-one clinical laboratory isolates from both sterile and nonsterile sites were obtained from a local hospital. Isolates with reduced susceptibilities to penicillin represented 15.1 and 42.9% of the nasopharyngeal and clinical isolates, respectively. For neither group of isolates did penicillin MICs exceed 1.5 μg/ml, indicating only intermediate resistance. Thirty-two different serotypes were identified from the 146 nasopharyngeal isolates. The serotypes of the clinical isolates were represented among those 32 types. Isolates with reduced susceptibility to multiple antimicrobial agents were present in both settings. These findings indicate some of the highest rates of antimicrobial resistance in the region as well as a slightly different serotype distribution pattern from those of other South American countries. The 7-valent conjugate pneumococcal vaccines would only have a limited effect, providing coverage for about half of all isolates. Increasing rates of resistance in Peru necessitate an awareness of antimicrobial treatment practices and vaccination strategies.

Background: General practitioner (GP) prescribing accounts for about 10% of NHS expenditure. GPs at the top of the range have annual prescribing costs that are almost twice as much as those at the bottom of the range. This variation cannot be accounted for purely in terms of differences in underlying need for health care.

Objectives: To describe the relationship between GPs' prescribing costs and their attitudes towards prescribing decisions and prescribing information sources, and to identify potentially modifiable attitudinal and behavioural factors associated with high cost prescribing.

Design: A postal questionnaire was designed on the basis of hypotheses developed from a literature search and an earlier qualitative survey. This questionnaire was sent to a national sample of GPs with equal numbers of practices in the upper, middle, and lowest quintile of prescribing costs.

Setting: GP practices in England.

Participants: 1714 GPs in NHS practice.

Outcome measures: GPs' self-reported practices, attitudes and personal characteristics.

Results: There was a 64% response rate. Responders were more likely to be from larger practices, in less deprived areas, and with lower prescribing costs than were non-responders. Multivariable analysis showed that GPs with high prescribing costs were significantly more likely to work in dispensing practices, in practices with low income populations, in single handed practices, and in practices without a GP trainer. They were also significantly more likely to see drug company representatives more frequently, to prescribe newly available drugs more freely, to prescribe more readily to patients who expect a prescription, to report high levels of frustration from lack of time in the consultation, to find unsatisfactory those consultations which ended in advice only, and to express dissatisfaction with their review methods for repeat prescribing. They were significantly less likely to find useful criticism of prescribing habits by colleagues, and to check the BNF rather than other sources when uncertain about an aspect of drug treatment.

Conclusions: While they cannot be held to have a causal relationship, the pattern of attitudes towards prescribing of GPs in the highest quintile of prescribing costs provide the basis for developing an educational intervention which may be an acceptable method of modifying the attitudes of GPs and consequently reducing their prescribing costs.

Amrubicin (AMR) is one of the most active chemotherapeutic agents for small-cell lung cancer (SCLC). Previous phase II studies reported on its effectiveness and severe hematological toxicities. However, AMR has yet to be approved outside Japan. Subsequently, no extensive evidence of its effects exist. Between January 2004 and October 2009, 69 patients received AMR for relapsed SCLC at our hospital. We reviewed these patients, and analyzed the efficacy and hematological toxicities of AMR. There were 27 sensitive relapses (S) and 42 refractory relapses (R). Patients received platinum agents, and 43 and 71% of the patients received etoposide and irinotecan, respectively. The median number of treatment cycles was 3 (range 1–14), and the response rate was 51% (70% in the S and 38% in the R cases, respectively). In patients administered with AMR as second-line therapy, the response rate was 55% and as third-line therapy, 39%. Median progression-free survival time was 3.2 months in the S and 1.9 months in the R patients (p=0.1071). Median survival time from the start of AMR was 6.2 months in the S and 4.8 months in the R cases (p=0.0045). The frequency of grade ≥3 hematological toxicities was leukopenia (41%), neutropenia (51%), anemia (14%), thrombocytopenia (17%) and febrile neutropenia (12%). No treatment-related death was observed. Although hematological toxicities, particularly neutropenia, were severe, AMR showed excellent anti-tumor activity, not only in the S, but also in the R cases, as shown in previous phase II studies. These results warrant further evaluation of AMR in the second-line setting, and also in the first-line setting in both limited- and extensive-stage disease. We conducted a phase II study to assess the efficacy of consolidation chemotherapy with AMR after standard chemoradiation in limited-stage SCLC.

Background

Upper Respiratory Infections (URIs) are common in children. The cause is usually viral, but parents' attitude often contributes to inappropriate antibiotic prescribing, promoting antibiotic resistance. The objective is to describe the process of developing a questionnaire to assess parents' Knowledge, Attitude and Practices (KAP) concerning the role of antibiotics when children suffer from URIs, as well as to evaluate the response rates, the completeness and the reliability (Cronbach) of the questionnaires. Finally, to note any limitations of the study.

Methods

Literature review, along with pre – testing yielded a questionnaire designed to assess the parents' KAP – level. A postal survey was set, in a national sample of 200 schools stratified by geographical region. The participants consist of a multistage geographical cluster sample of 8000 parents. The influence of demographic characteristics (i.e. sex, age, education) was analyzed. Cronbach index test and factor analysis were used to assess the reliability of the questionnaire.

Results

The response rate of the parents was 69%. Islands presented the lowest response rate while in Northern Greece the response rate was the highest. Sixty – eight point nine percent of the sample returned questionnaires fully completed, while 91.5% completed 95% of the questions. Three questions out of 70 were answered in a very low rate which was associated mostly with immigrant respondents. The section describing parents' attitude toward antibiotic use was not completed as much as the sections of knowledge or practices. The questions were factor analyzed and 10 out of the 21 extracted factors were finally evaluated, reducing the number of independent variables to 46. The reliability of the questionnaire was 0.55. However, only items that increased the Cronbach when added were eventually included in the final scales raising the internal consistency to 0.68. Limitations of the study, such as the vocabulary and form of the questionnaire and the idiocycrancy of the respondents, emerged during the analysis.

Conclusion

The response rate and the completeness of the questionnaires were higher than expected, probably attributed to the involvement of the teachers. The study findings were satisfactory regarding the development of a reliable instrument capable to measure parents' KAP characteristics.

BACKGROUND: Knowledge, attitudes, and practices regarding antibiotic prescribing for upper respiratory tract infections (URIs) have not been well described among obstetrician-gynecologists (OB/GYNs). This information is useful for determining whether an OB/GYN-specific program promoting appropriate antibiotic use would significantly contribute to the efforts to decrease inappropriate antibiotic use among primary care providers. METHODS: An anonymous questionnaire asking about the treatment of URIs was sent to 1031 obstetrician-gynecologists. RESULTS: The overall response rate was 46%. The majority of respondents (92%) were aware of the relationship between antibiotic use and antibiotic resistance, and respondents estimated that 5% of their patients had URI symptoms at their office visits. Overall, 56% of respondents reported that they would prescribe an antibiotic for uncomplicated bronchitis and 43% for the common cold. OB/GYNs with the fewest years of experience were less likely than those with the most years of experience to report prescribing for uncomplicated bronchitis (Odds ratio (OR) 0.46, 95% confidence interval (CI) 0.23 to 0.91) or the common cold (OR 0.44, CI 0.22 to 0.89). The majority of respondents (60%) believed that most patients wanted an antibiotic for URI symptoms, with male OB/GYNs being more likely than female OB/GYNs (OR 2.1, CI 1.2 to 3.8) to hold this belief. Both male OB/GYNs (OR 1.9, CI 1.1 to 3.4) and rural practitioners (OR 2.1, CI 1.1 to 4.0) were more likely to believe that it was hard to withhold antibiotics for URI symptoms because other physicians prescribe antibiotics for these symptoms. OB/GYNs who believed that postgraduate training prepared them well for primary care management were more likely than those who did not (OR 2.1, CI 1.1 to 4.2) to believe that they could reduce antibiotic prescribing without reducing patient satisfaction. CONCLUSION: Multiple demographic factors affect attitudes and reported practices regarding antibiotic prescribing. However, in view of the low proportion of office visits for URIs, an OB/GYN-specific program is not warranted.

Objectives

To estimate Chlamydia trachomatis (CT) infection prevalence and associated risk factors among a low-income marginalized urban population in Peru.

Methods

Between April 2003 and April 2005, men and women at high-risk for sexually transmitted infections (STIs) were recruited from low-income urban areas in three coastal cities in Peru (Chiclayo, Lima, and Trujillo). Consenting participants were studied using a sero-epidemiologic survey. Urine and vaginal swabs collected from men and women were evaluated using polymerase chain reaction (PCR) (COBAS® AMPLICOR (CT/NG) Test, Roche Molecular Diagnostics, Branchburg, NJ, USA) for CT.

Results

Among the 2 440 participants recruited for the study (2 145 men and 295 women), overall prevalence of CT infection was 6.6% (95% CI, 5.6–7.6%): 5.5% (95% CI, 4.5–6.5%) in men and 14.9% (95% CI, 11.7–27.1%) in women. Chlamydial infection was inversely associated with age and positively associated with HIV infection and dysuria in men. Among women, chlamydial infection was inversely associated with age and positively associated with number of sex partners.

Conclusions

CT infection was common among high-risk men and women in urban coastal Peru. Because chlamydial infection is associated with complications related to female reproduction, including infertility and ectopic pregnancy, interventions to prevent and treat infection and studies to determine the feasibility of population-based screening for CT should be conducted among the high-risk female population.

Abstract

Objective

To evaluate the feasibility and effectiveness of a multifaceted educational intervention to improve the opioid prescribing practices of rural family physicians in a remote First Nations community.

Design

Prospective cohort study.

Setting

Sioux Lookout, Ont.

Participants

Family physicians.

Interventions

Eighteen family physicians participated in a 1-year study of a series of educational interventions on safe opioid prescribing. Interventions included a main workshop with a lecture and interactive case discussions, an online chat room, video case conferencing, and consultant support.

Main outcome measures

Responses to questionnaires at baseline and after 1 year on knowledge, attitudes, and practices related to opioid prescribing.

Results

The main workshop was feasible and was well received by primary care physicians in remote communities. At 1 year, physicians were less concerned about getting patients addicted to opioids and more comfortable with opioid dosing.

Conclusion

Multifaceted education and consultant support might play an important role in improving family physician comfort with opioid prescribing, and could improve the treatment of chronic pain while minimizing the risk of addiction.

This paper presents the lessons learned through a process evaluation (PE) after one year of implementation of a two-year community intervention in Lima, Peru. The intervention consisted of training and motivating community popular opinion leaders (CPOLs) for three marginal population segments to disseminate prevention messages among their peers. PE data included: observations, qualitative interviews with CPOLS, conversations and messages delivered by CPOLs, training facilitators' perceptions about implementation, and a survey of CPOLs. The PE helped to document and enhance the intervention. CPOLs were motivated to talk to their peers. CPOLs perceived that their participation had an effect on their own risk behaviors and saw their role as beneficial to their community. The PE was helpful in examining training delivery and the feasibility and acceptability of the intervention in order to assess the elements related to program success necessary to replicate the CPOL model.

Objective

Recent changes in postgraduate medical training in the UK collectively organized under the auspices of Modernising Medical Careers (MMC) have created new labels for junior doctors in training. It would appear that many nurses and other health workers do not understand the new terminology. We aimed to investigate the knowledge of nursing staff about new junior doctor titles in a district general hospital. As far as we are aware, this is the first survey to determine the views and knowledge of the new terms among staff working in the NHS.

Design

Questionnaire study.

Setting

District general hospital, West Midlands, UK.

Participants

Fifty-five randomly selected staff nurses working in the surgical directorate.

Main outcome measure

Questions were asked about their views and knowledge of the current nomenclature. To objectively assess knowledge of the new titles respondents were asked to match equivalent positions with those based on the old system.

Results

Only 22% (n = 12) of respondents felt that they fully understand current terms in usage. Seventy-six percent (n = 42) felt that it was ‘very important’ that titles accurately convey role and seniority of the doctor. The most common titles correctly matched were FY1 and House Officer (n = 45, 81%) and FY2 and First Year Senior House Officer (n = 35, 64%). Only 9% (n = 5) of staff nurses correctly matched ST3 to Junior Registrar and 13% (n = 7) correctly matched ST7 to Senior Registrar. Ward-based staff nurses demonstrated greater familiarity with titles when compared to nurses who work mainly in the outpatient clinic and theatre setting (p = 0.017). We did not identify a statistically significant association with demographic characteristics (age, gender, experience) and knowledge of the new terms (p > 0.05). Approximately 98% (n = 54) of the staff surveyed felt that terms are confusing to nurses and need to be simplified.

Conclusions

Our survey revealed that nursing staff lacked knowledge of the current terminology to describe doctors in training. This may have implications for staff expectations regarding specific role of junior doctor in terms of clinical decision-making, working relationships and communication between team members, and ultimately patient care.
