Background

Tinnitus is a prevalent and complex medical complaint often co-morbid with stress, anxiety, insomnia, depression, and cognitive or communication difficulties. Its chronicity places a major burden on primary and secondary healthcare services. In our recent national survey of General Practitioners (GPs) from across England, many reported that their awareness of tinnitus was limited and as a result were dissatisfied with the service they currently provide. GPs identified 10 online sources of information they currently use in clinical practice, but welcomed further concise and accurate information on tinnitus assessment and management. The purpose of this study was to assess the content, reliability, and quality of the information related to primary care tinnitus assessment and management on these 10 websites.

Methods

Tinnitus related content on each website was assessed using a summative content analysis approach. Reliability and quality of the information was assessed using the DISCERN questionnaire.

Results

Quality of information was rated using the validated DISCERN questionnaire. Significant inter-rater reliability was confirmed by Kendall’s coefficient of concordance (Wt) which ranged from 0.48 to 0.92 across websites. The website Map of Medicine achieved the highest overall DISCERN score. However, for information on treatment choice, the British Tinnitus Association was rated best. Content analysis revealed that all websites lacked a number of details relating to either tinnitus assessment or management options.

Conclusions

No single website provides comprehensive information for GPs on tinnitus assessment and management and so GPs may need to refer to more than one if they want to maximise their coverage of the topic. From those preferred by GPs we recommend several specific websites as the current ‘best’ sources. Our findings should guide healthcare website providers to improve the quality and inclusiveness of the information they publish on tinnitus. In the case of one website, our preliminary findings are already doing so. Such developments will in turn help facilitate best practice in primary care.

Background

Spinal bulbar muscular atrophy (SBMA) is caused by a CAG repeat expansion mutation in the androgen receptor (AR) gene, and mutant AR is presumed to act in motoneurons to cause SBMA. However, we found that mice overexpressing wild-type (wt) AR solely in skeletal muscle fibers display the same androgen-dependent disease phenotype as when mutant AR is broadly expressed, challenging the assumptions that only an expanded AR can induce disease and that SBMA is strictly neurogenic. We have previously reported that AR toxicity was ligand dependent in our model, and that very few transgenic (tg) males survived beyond birth.

Methods

We tested whether the AR antagonist flutamide could block perinatal toxicity. tg males were treated prenatally with flutamide and assessed for survival and motor behavior in adulthood.

Results

Prenatal treatment with flutamide rescued tg male pups from perinatal death, and, as adults, such perinatally rescued tg males showed an SBMA phenotype that was comparable to that of previously described untreated tg males. Moreover, tg males carrying a mutant endogenous allele for AR – the testicular feminization mutation (tfm) – and thus having functional AR only in muscle fibers nevertheless displayed the same androgen-dependent disease phenotype as adults.

Conclusions

These mice represent an excellent model to study the myogenic contribution to SBMA as they display many of the core features of disease as other mouse models. These data demonstrate that AR acting exclusively in muscle fibers is sufficient to induce SBMA symptoms and that flutamide is protective perinatally.

We explored health literacy in parents as an underlying construct that develops through social interaction and reflection and involves an array of skills that enable a parent to manage personal and child health and healthcare. We hypothesized that depression impairs health literacy and impedes efforts to promote health literacy through home visitation. We analyzed an AHRQ/NIH database of 2,572 parent/child dyads compiled in a 2006–2008 quasi-experimental six-site nationwide study using multiple waves of measurement and a matched comparison group. Cohort families participated in home visitation programs augmented to develop parents’ reflective skills. Visitors monitored depression, health- and healthcare-related practices, and surrounding family conditions at baseline and 6-month intervals for up to 36 months using the Life Skills Progression instrument. We examined differences in initial depression ratings for demographic subgroups and explored patterns of change in health literacy among depressed versus not-depressed parents. Correlation analysis showed that at each of four assessments better depression scores were consistently and positively correlated with use of information and services (r = 21–22, P < .001) and with self-management of personal and child health (r = 42–49, P < .001). Overall, parents made significant improvements in health literacy (P < .001). As expected, depressed parents demonstrated lower baseline health literacy scores than not-depressed parents; however, they achieved greater gains (P < .001). While depression is linked with lower parental health literacy, after 1 year of enhanced home visitation, vulnerable parents were better able to manage personal and family health and healthcare, especially if depressed. Enhanced home visitation could be an effective channel to develop health literacy as a life skill, and to improve depression.

Background

In the UK, audiology services deliver the majority of tinnitus patient care, but not all patients experience the same level of service. In 2009, the Department of Health released a Good Practice Guide to inform commissioners about key aspects of a quality tinnitus service in order to promote equity of tinnitus patient care in UK primary care, audiology, and in specialist multi-disciplinary centres. The purpose of the present research was to evaluate utilisation and opinions on pathways for the referral of tinnitus patients to and from English Audiology Departments.

Methods

We surveyed all audiology staff engaged in providing tinnitus services across England. A 36-item questionnaire was mailed to 351 clinicians in all 163 National Health Service (NHS) Trusts identified as having a tinnitus service. 138 clinicians responded. The results presented here describe experiences and opinions of the current patient pathways to and from the audiology tinnitus service.

Results

The most common referral pathway was from general practice to a hospital-based Ear, Nose & Throat department and from there to a hospital-based audiology department (64%). Respondents considered the NHS tinnitus referral process to be generally effective (67%), but expressed needs for improving GP referral and patients' access to services. 'Open access' to the audiology clinic was rarely an option for patients (9%), nor was the opportunity to access specialist counselling provided by clinical psychology (35%). To decrease the number of inappropriate referrals, 40% of respondents called for greater awareness by referrers about the audiology tinnitus service.

Conclusions

Respondents in the present survey were generally satisfied with the tinnitus referral system. However, they highlighted some potential targets for service improvement including 1] faster and more appropriate referral from GPs, to be achieved through education on tinnitus referral criteria, 2] improved access to psychological services through audiologist training, and 3] ongoing support from tinnitus support groups, national charities, or open access to the tinnitus clinic for existing patients.

Confusion about patients’ medication regimens during the hospital admission and discharge process accounts for many preventable and serious medication errors. Many organizations have begun to redesign their clinical processes to address this patient safety concern. Partners HealthCare, an integrated delivery network in Boston, Massachusetts, has answered this interdisciplinary challenge by leveraging its multiple outpatient electronic medical records (EMR) and inpatient computerized provider order entry (CPOE) systems to facilitate the process of medication reconciliation. This manuscript describes the design of a novel application and the associated services that aggregate medication data from EMR and CPOE systems so that clinicians can efficiently generate an accurate pre-admission medication list. Information collected with the use of this application subsequently supports the writing of admission and discharge orders by physicians, performance of admission assessment by nurses, and reconciliation of inpatient orders by pharmacists. Results from early pilot testing suggest that this new medication reconciliation process is well accepted by clinicians and has significant potential to prevent medication errors during transitions of care.

Unintended medication discrepancies at hospital admission and discharge potentially harm patients. Explicit medication reconciliation (MR) can prevent unintended discrepancies among care settings and is mandated by JCAHO for 2005. Enterprise-wide, we are linking pre-admission and discharge medication lists in our outpatient electronic health records (EHR) with our inpatient order entry applications (OE) - currently not interoperable - to support MR and inform the development of comprehensive MR among hospitalized patients.

2-Acetylpyridine thiosemicarbazone derivatives inhibited the replication of herpes simplex virus types 1 and 2 to a greater extent than cellular deoxyribonucleic acid or protein synthesis.

The drug 9-β-d-arabinofuranosyladenine (ara-A) significantly suppressed the formation of herpes simplex virus type 1-induced syncytia in BHK-21/4 cells at concentrations as low as 0.1 μg/ml. Optimal activity was noted when the drug was added before initiation of viral deoxyribonucleic acid (DNA) synthesis (3.5 h postinfection). The deaminated derivative of ara-A, 9-β-d-arabinofuranosylhypoxanthine (ara-H), was at least 10 times less effective in suppressing the development of herpes simplex virus-induced syncytia. The replication of herpes simplex virus was measured by assaying fluids and cells from infected drug-treated cultures by using a plaque production technique. Ara-A at drug levels of >10 < 32 μg/ml completely blocked the replication of infectious virus particles. Ara-H was less effective than ara-A in reducing the replication of virions. Rates of host and viral DNA synthesis were monitored by pulse labeling herpes simplex virus-infected synchronized KB cells with [3H]thymidine and subsequently separating viral from cellular DNA in CsCl density gradients. During synthetic (S) phase, ara-A or ara-H at concentrations ranging from 3.2 to 32 μg/ml selectively inhibited viral DNA synthesis. At 3.2 μg of ara-A per ml, viral DNA synthesis was reduced 74% although total cellular DNA synthesis was unaffected. Increasing concentrations of ara-A produced increasing temporal delays in the maximal rate of host DNA synthesis. This time shift was not observed in cells treated with ara-H.

Rationale, aim and objective

Effective tinnitus management starts with appropriate general practitioner (GP) triage, which in England can be guided by the Department of Health's Good Practice Guide (GPG). Despite the prevalence of the condition, there has never been a systematic survey of its management in primary care in England. We aimed to evaluate how people with tinnitus are assessed and managed in general practice, noting variation in practice across GPs and health authorities, and evaluating how closely typical practice aligns to the GPG for tinnitus.

Methods

A nine-item postal questionnaire was sent to 2000 GPs randomly selected to proportionally represent the number of primary care trusts and strategic health authorities in England.

Results

We received 368 responses. Responses indicated a mix of frequent and infrequent practices, for example, 90% of GPs assessed the impact of tinnitus on quality of life, but fewer examined cranial nerves (38%) or assessed for a carotid bruit (26%) during a tinnitus consultation. In the management of tinnitus, 83% routinely removed earwax, and 87% provided information-based advice. In contrast, only 4% of responders would offer antidepressant drugs or psychological therapies. Thematic analysis revealed a desire for concise training on tinnitus management.

Conclusions

GP assessment and management of tinnitus represents potential inequity of service for tinnitus patients. While the GPG aims to promote equity of care, it is only referred to by a minority of clinicians and so its utility for guiding service delivery is questionable. Although some GPs highlighted little demand for tinnitus management within their practice, many others expressed an unmet need for specific and concise GP training on tinnitus management. Further work should therefore evaluate current informational resources and propose effective modes of delivering educational updates.

Rationale, aim and objective

In 2009, the UK Department of Health formalized recommended National Health Service practices for the management of tinnitus from primary care onwards. It is timely therefore to evaluate the perceived practicality, utility and impact of those guidelines in the context of current practice.

Methods

We surveyed current practice by posting a 36-item questionnaire to all audiology and hearing therapy staff that we were able to identify as being involved in tinnitus patient care in England.

Results

In total, 138 out of 351 clinicians responded (39% response rate). The findings indicate a consensus opinion that management should be tailored to individual symptom profiles but that there is little standardization of assessment procedures or tools in use.

Conclusions

While the lack of standardized practice might provide flexibility to meet local demand, it has drawbacks. It makes it difficult to ascertain key standards of best practice, it complicates the process of clinical audit, it implies unequal patient access to care, and it limits the implementation of translational research outcomes. We recommend that core elements of practice should be standardized, including use of a validated tinnitus questionnaires and an agreed pathway for decision making to better understand the rationale for management strategies offered.
