Electronic health record (EHR)-based alerts can facilitate transmission of test results to healthcare providers, helping ensure timely and appropriate follow-up. However, failure to follow-up on abnormal test results (missed test results) persists in EHR-enabled healthcare settings. We aimed to identify contextual factors associated with facility-level variation in missed test results within the Veterans Affairs (VA) health system.
Design, setting and participants
Based on a previous survey, we categorised VA facilities according to primary care providers’ (PCPs’) perceptions of low (n=20) versus high (n=20) risk of missed test results. We interviewed facility representatives to collect data on several contextual factors derived from a sociotechnical conceptual model of safe and effective EHR use. We compared these factors between facilities categorised as low and high perceived risk, adjusting for structural characteristics.
Facilities with low perceived risk were significantly more likely to use specific strategies to prevent alerts from being lost to follow-up (p=0.0114). Qualitative analysis identified three high-risk scenarios for missed test results: alerts on tests ordered by trainees, alerts ‘handed off’ to another covering clinician (surrogate clinician), and alerts on patients not assigned in the EHR to a PCP. Test result management policies and procedures to address these high-risk situations varied considerably across facilities.
Our study identified several scenarios that pose a higher risk for missed test results in EHR-based healthcare systems. In addition to implementing provider-level strategies to prevent missed test results, healthcare organisations should consider implementing monitoring systems to track missed test results.

Anxiety has a high prevalence among individuals with dementia, and it has a significant negative impact on their functioning; yet intervention studies are lacking. We developed Peaceful Mind, a cognitive-behavioral intervention for persons with dementia. In this article, we describe the intervention and results of an open trial evaluating the feasibility and utility of the intervention and assessment procedures.
Peaceful Mind is implemented over a period of 3 months in the participant's home with involvement of a caregiver or “collateral.” Dyads are followed for an additional 3 months via telephone. An assortment of simplified skills is offered, including self-awareness, breathing, behavioral activation, calming thoughts, and sleep skills.
Nine participants were enrolled, eight completed the 3-month assessment, and seven completed the 6-month assessment. Overall, participants and collaterals were satisfied with the intervention and reported that they benefited in terms of anxiety, depression, and collateral distress.
A randomized controlled trial would help determine whether this promising new treatment has a statistically significant impact on anxiety in this population.

Relatively little attention has focused on the impact of psychiatric conditions
on human subjects’ comprehension of consent information. The purpose of this
randomized study was to determine whether depression affects comprehension and recall of
informed consent information among persons with Parkinson's disease and their caregivers
and to evaluate the effects of support on comprehension and recall during the consent
Comprehension and recall of information were assessed using a modified version
of the Modified Quality of Informed Consent Questionnaire, taken 1 week and 1 month
later, and scored using a consensus-based algorithm. Participants also completed the
Center for Epidemiologic Studies Depression Scale. Data analyses were conducted on 129
patients and caregivers (t-tests, Fisher's exact test, and
T-tests showed no significant differences in comprehension and
recall between depressed and nondepressed participants at 1 week and 1 month. However,
ANCOVA showed patients with a support person present had significantly higher
comprehension and recall at 1 week but not at 1 month compared with controls. Caregivers
present with a patient had lower comprehension/recall than those without a patient
present (p = 0.02).
Having a support person present during the informed consent process helps
depressed PD patients better retain information in the short term, but effects diminish
over the long term. Implications for interventions will be discussed.

To assess feasibility and to conduct a preliminary evaluation of outcomes following Peaceful Mind, a CBT-based intervention for anxiety in dementia, relative to usual care (UC).
Pilot randomized controlled trial including assessments at baseline, 3 and 6 months
32 outpatients diagnosed with mild (47%) or moderate (53%) dementia receiving care through outpatient clinics at the Veterans Affairs medical center, Baylor College of Medicine, Harris County Hospital District and community day centers for dementia, and their collaterals, who spent at least 8 hours a week with them.
Peaceful Mind included up to 12 weekly in-home sessions (mean = 8.7, SD = 2.27) during the initial 3 months and up to eight brief telephone sessions (mean = 5.4, SD = 3.17) during months 3 to 6, involving self-monitoring for anxiety, deep breathing, and optional skills (coping self-statements, behavioral activation and sleep management). Patients learned skills, and collaterals served as coaches. In UC, patients received diagnostic feedback; and providers were informed of inclusion status.

Feasibility was demonstrated with regard to recruitment, attrition, and treatment characteristics. At 3 months, clinicians rated patients receiving Peaceful Mind as less anxious, and patients rated themselves as having higher quality of life; collaterals reported less distress related to loved ones’ anxiety. Although significant positive effects were not noted in other outcomes or at 6-month follow-up, the pilot nature of the trial prohibits conclusions about efficacy.
Results support that Peaceful Mind is ready for future comparative clinical trials.

Recent evidence indicates increased access to and use of Internet and non-healthcare-related email by older patients. Because email adoption could potentially reduce some of the disparities faced by this age group, there is a need to understand factors determining older patients’ enthusiasm to use email to communicate with their physicians. Electronic mail (email) represents a means of communication that, coupled with face-to-face communication, could enhance quality of care for older patients.
Test a model to determine factors associated with older patients’ enthusiasm to use email to communicate with their physicians.
We conducted a secondary data analysis of survey data collected in 2003 for two large, longitudinal, randomized controlled trials. Logistic-regression models were used to model the dichotomous outcome of patient enthusiasm for using email to communicate with their physicians. Explanatory variables included demographic characteristics, health status, use of email with people other than their physician, characteristics of the physician-patient relationship, and physician enthusiasm to use email with patients.
Participants included a pooled sample of 4059 patients over 65 years of age and their respective physicians (n = 181) from community-based practices in Southern California. Although only 52 (1.3%) patient respondents reported that they communicated with their physician by email, about half (49.3%) expressed enthusiasm about the possibility of using it. Odds of being enthusiastic decreased with increased age (by 0.97 for each year over 66) but were significantly higher in African Americans (OR = 2.1, CI = 1.42 - 3.06), Hispanics (OR = 1.6, CI = 1.26 - 2.14) and men (OR = 1.3, CI = 1.1 - 1.5).
A perception of better communication skills of their physician, lower quality of interaction with physician in traditional face-to-face encounters, and physician enthusiasm to use email with patients were significantly associated with an enthusiasm to use email. Patients who did not use email at all were less enthusiastic compared to those who used email for other reasons. Half of the physician respondents were not enthusiastic about communicating with patients using email.
Despite perceived barriers such as limited access to the Internet, older patients seem to want to use email to communicate with their physicians.

Depression and diabetes cause significant burden for patients and the healthcare system and, when co-occurring, result in poorer self-care behaviors and worse glycemic control than for either condition alone. However, the clinical management of these comorbid conditions is complicated by a host of patient, provider, and system-level barriers that are especially problematic for patients in rural locations. Patient-centered medical homes provide an opportunity to integrate mental and physical health care to address the multifaceted needs of complex comorbid conditions. Presently, there is a need to not only develop robust clinical interventions for complex medically ill patients but also to find feasible ways to embed these interventions into the frontlines of existing primary care practices.
This randomized controlled trial uses a hybrid effectiveness-implementation design to evaluate the Healthy Outcomes through Patient Empowerment (HOPE) intervention, which seeks to simultaneously address diabetes and depression for rural veterans in Southeast Texas. A total of 242 Veterans with uncontrolled diabetes and comorbid symptoms of depression will be recruited and randomized to either the HOPE intervention or to a usual-care arm. Participants will be evaluated on a host of diabetes and depression-related measures at baseline and 6- and 12-month follow-up. The trial has two primary goals: 1) to examine the effectiveness of the intervention on both physical (diabetes) and emotional health (depression) outcomes and 2) to simultaneously pilot test a multifaceted implementation strategy designed to increase fidelity and utilization of the intervention by coaches interfacing within the primary care setting.
This ongoing blended effectiveness-implementation design holds the potential to advance the science and practice of caring for complex medically ill patients within the constraints of a busy patient-centered medical home.

We compared the psychometric performance of two validated self-report anxiety- symptom measures when rated by people with dementia versus collaterals (as proxies). Forty-one participants with mild-to-moderate dementia and their respective collaterals completed the Geriatric Anxiety Inventory, the Penn State Worry Questionnaire-Abbreviated, and a structured diagnostic interview. We used descriptive and nonparametric statistics to compare scores according to respondent characteristics. Receiver operating characteristic (ROC) curves were calculated to establish the predictive validity of each instrument by rater type against a clinical diagnosis of an anxiety disorder. Participant and collateral ratings performed comparably for both instruments. However, collaterals tended to give more severe symptom ratings, and the best-performing cut-off scores were higher for collaterals. Our findings suggest that people with mild-to-moderate dementia can give reliable self-reports of anxiety symptoms, with validity comparable to reports obtained from collaterals. Scores obtained from multiple informants should be interpreted in context.

We conducted a population-based study to describe the utilization, determinants, and survival effects of adjuvant therapies following surgery among older patients with pancreatic cancer.
Using SEER-Medicare data, we identified patients >65 years who received surgical resection for pancreatic cancer during 1992–2002. We constructed multiple logistic regression models to examine patient, clinical, and hospital factors associated with receiving adjuvant therapy. Cox proportional hazards models were used to examine the effect of therapy on survival.
Approximately 49% of patients received adjuvant therapy following surgery. Patient factors associated with increased receipt of adjuvant therapy included more recent diagnosis, younger age, stage II disease, higher income, and geographic location. Hospital factors associated with increased receipt of adjuvant therapy included cooperative group membership and larger size. Adjuvant treatments associated with a significant reduction in 2-year mortality (relative to surgery alone) were chemoradiation or radiation alone, but not chemotherapy alone.
Our findings suggest that adjuvant chemoradiation and to a lesser degree radiation only, are associated with a reduction in the risk of mortality among older patients who undergo surgery for pancreatic cancer. However, receipt of adjuvant therapy varied by time period and geography as well as certain patient and hospital factors.

The accuracy of the diagnosis is vital when administrative databases are used for pharmacoepidemiologic and outcome studies. Data pertaining to the utility of databases for rheumatoid arthritis (RA) is sparse and variable. We assessed the utility of various diagnostic algorithms to identify RA patients within the Veterans Health Administration (VHA) databases.
Using the ICD code for RA at two visits, at least six months apart, we identified 1779 patients between 10/1/1998 and 9/30/2009 in our local Veteran Affairs Medical Center administrative database. Disease Modifying Anti Rheumatic Drugs (DMARD) use was ascertained from the pharmacy database. Cases were analyzed based on DMARD therapy and RA codes at clinic visits. 543 patients' medical records selected by stratification and random selection on the basis of their visits were reviewed to ascertain the clinicians' diagnoses and clinical criteria documentation. Positive predictive values (PPV) were calculated for various database case identification algorithms using diagnosis of RA by medical record review as the gold standard.
PPV for identification of RA with two RA codes six months apart was 30.9%. Addition of DMARD therapy increased the PPV to 60.4%. The PPV further increased to 91.4% when having RA code at the last VAMC rheumatology clinic visit criterion was added.
An algorithm using only two administrative RA codes six months apart had a low PPV for correctly identifying patients with RA in the VHA database. Including DMARD therapy and requiring a RA code at the last visit with a rheumatologist increased the performance of the data extraction algorithm.

The Rating Anxiety in Dementia (RAID; Shankar et al, 1999)is a clinical rating scale developed to evaluate anxiety in persons with dementia. This report explores the psychometric properties and clinical utility of a new structured interview format of the RAID (RAID-SI), developed to standardize administration and scoring based on information obtained from the patient, an identified collateral, and rater observation.
The RAID-SI was administered by trained master’s level raters. Participants were 32 persons with dementia who qualified for an anxiety treatment outcome study. Self-report anxiety, depression, and quality of life measures were administered to both the person with dementia and a collateral.
The RAID-SI exhibited adequate internal consistency reliability and inter-rater reliability. There was also some evidence of construct validity as indicated by significant correlations with other measures of patient-reported and collateral-reported anxiety, and non-significant correlations with collateral reports of patient depression and quality of life. Further, RAID-SI scores were significantly higher in persons with an anxiety diagnosis compared to those without an anxiety diagnosis.
There is evidence that the RAID-SI exhibits good reliability and validity in older adults with dementia. The advantage of the structured interview format is increased standardization in administration and scoring, which may be particularly important when RAID raters are not experienced clinicians.

We present the development and validation of a theory-derived scale measuring patients' behavioral intention to adhere to HIV care. Adherence to HIV care includes attendance at appointments and adherence to highly active antiretroviral therapy (HAART) regimens. These two components have been independently associated with long-term HIV outcomes. Items were chosen to reflect behavioral intention as defined by the Health Action Process Approach to health-seeking behavior. Items reflecting self-reported HIV knowledge were also included after expert panel review. The study took place from October 2009 to April 2010 at two HIV clinics in Houston, Texas. Participants were 287 adults with HIV/AIDS (10.1% female, mean age 50.8); 56.5% were African-American and 17% were Hispanic. Of the total, 87.1% were on HAART at enrollment. Factor analysis of survey items resulted in the retention of two domains, knowledge and intention, based on scree plot analysis of eigenvalues. Questions with factor loadings >0.4 were retained, yielding 4 knowledge questions and 10 intention questions. The survey had good internal consistency for knowledge (Cronbach's α=0.83) and for intention (Cronbach's α=0.81). In multivariate analysis, intention was associated with HIV viral suppression, defined as HIV-1 viral load <400 RNA copies/mL, (odds ratio [OR]=1.75, 95% .confidence interval [CI]=1.00–3.07). Knowledge was also associated with HIV suppression (OR=1.55, 95%, CI=1.09–2.12). The resulting study describes the development and preliminary validation of an HIV treatment-seeking intention measure. Additional studies are needed to validate this instrument in other populations.
Early detection of dysphagia is critical in stroke as it improves health care outcomes. Administering a swallowing screening tool (SST) in the emergency department (ED) appears most logical as it is the first point of patient contact. However, feasibility of an ED nurse-administered SST, particularly one involving trial water swallow administration, is unknown. The aims of this pilot study were to (1) implement an SST with a water swallow component in the ED and track nurses' adherence, (2) identify barriers and facilitators to administering the SST through interviews, and (3) develop and implement a process improvement plan to address barriers. Two hundred seventy-eight individuals with stroke symptoms were screened from October 2009 to June 2010. The percentage of patients screened increased from 22.6 in October 2009 to a high of 80.8 in March 2010, followed by a decrease to 61.9% in June (Cochran-Armitage test z = −5.1042, P < 0.0001). The odds of being screened were 4.0 times higher after implementation compared to two months before implementation. Results suggest that it is feasible for ED nurses to administer an SST with a water swallow component. Findings should facilitate improved quality of care for patients with suspected stroke and improve multidisciplinary collaboration in swallowing screening.
Failure to notify patients of test results is common even when electronic health records (EHRs) are used to report results to practitioners. We sought to understand the broad range of social and technical factors that affect test result management in an integrated EHR-based health system.
Between June and November 2010, we conducted a cross-sectional, web-based survey of all primary care practitioners (PCPs) within the Department of Veterans Affairs nationwide. Survey development was guided by a socio-technical model describing multiple inter-related dimensions of EHR use.
Of 5001 PCPs invited, 2590 (51.8%) responded. 55.5% believed that the EHRs did not have convenient features for notifying patients of test results. Over a third (37.9%) reported having staff support needed for notifying patients of test results. Many relied on the patient's next visit to notify them for normal (46.1%) and abnormal results (20.1%). Only 45.7% reported receiving adequate training on using the EHR notification system and 35.1% reported having an assigned contact for technical assistance with the EHR; most received help from colleagues (60.4%). A majority (85.6%) stayed after hours or came in on weekends to address notifications; less than a third reported receiving protected time (30.1%). PCPs strongly endorsed several new features to improve test result management, including better tracking and visualization of result notifications.
Despite an advanced EHR, both social and technical challenges exist in ensuring notification of test results to practitioners and patients. Current EHR technology requires significant improvement in order to avoid similar challenges elsewhere.

The clinical importance of an elevated platelet count is often overlooked, particularly as a diagnostic clue to the presence of an underlying infection. We sought to better describe the relationship between thrombocytosis and inflammatory conditions, with a focus on infectious causes.
We retrospectively reviewed 801 sequential cases of thrombocytosis (platelet count > 500 × 109/L) at a tertiary care hospital.
Essential thrombocythemia was the most common cause of primary thrombocytosis, and these patients were more likely to have extreme (> 800 × 109/L) and prolonged (> 1 month) thrombocytosis. Secondary thrombocytosis was more common than primary, with infectious causes accounting for nearly half the cases. Demographic factors associated with an infectious etiology included inpatient status, quadriplegia/paraplegia, an indwelling prosthesis, dementia and diabetes. Clinical and laboratory characteristics associated with an infectious cause of thrombocytosis included fever, tachycardia, weight loss, hypoalbuminemia, neutrophilia, leukocytosis and anemia. Patients with thrombocytosis secondary to infection had a more rapid normalization of platelet count, but higher risk of dying, than those with secondary, non-infectious causes.
Infection is a common cause of thrombocytosis and should be considered in patients with comorbidities that increase risk of infection and when clinical and/or laboratory data support an infectious etiology. Thrombocytosis may have prognostic implications as a clinical parameter.

Overlap of cognitive and anxiety symptoms (i.e., difficulty concentrating, fatigue, restlessness) contributes to inconsistent, complicated assessment of generalized anxiety disorder (GAD)in persons with dementia.
Anxious dementia patients completed a psychiatric interview, the Penn State Worry Questionnaire-Abbreviated, and the Rating for Anxiety in Dementia scale. Analyses to describe the 43 patients with and without GAD included the Wilcoxon Mann-Whitney two-sample test, Fisher’s exact test. Predictors of GAD diagnosis were identified using logistic regression.
Those with GAD were more likely to be male, have less severe dementia and endorsed more worry, and anxiety compared to patients without GAD. Gender, muscle tension and fatigue differentiated those with GAD from those without GAD.
Although this study is limited by a small sample, it describes clinical characteristics of GAD in dementia, highlighting the importance of muscle tension and fatigue in recognizing GAD in persons with dementia.

Despite the availability of evidence-based psychotherapies for depression and anxiety, they are underused in non-mental health specialty settings such as primary care. Hybrid effectiveness-implementation designs have the potential to evaluate clinical and implementation outcomes of evidence-based psychotherapies to improve their translation into routine clinical care practices.
This protocol article discusses the study methodology and implementation strategies employed in an ongoing, hybrid, type 2 randomized controlled trial with two primary aims: (1) to determine whether a brief, manualized cognitive behavioral therapy administered by Veterans Affairs Primary Care Mental Health Integration program clinicians is effective in treating depression and anxiety in a sample of medically ill (chronic cardiopulmonary diseases) primary care patients and (2) to examine the acceptability, feasibility, and preliminary outcomes of a focused implementation strategy on improving adoption and fidelity of brief cognitive behavioral therapy at two Primary Care-Mental Health Integration clinics. The study uses a hybrid type 2 effectiveness/implementation design to simultaneously test clinical effectiveness and to collect pilot data on a multifaceted implementation strategy that includes an online training program, audit and feedback of session content, and internal and external facilitation. Additionally, the study engages the participation of an advisory council consisting of stakeholders from Primary Care-Mental Health Integration, as well as regional and national mental health leaders within the Veterans Administration. It targets recruitment of 320 participants randomized to brief cognitive behavioral therapy (n = 200) or usual care (n = 120). Both effectiveness and implementation outcomes are being assessed using mixed methods, including quantitative evaluation (e.g., intent-to-treat analyses across multiple time points) and qualitative methods (e.g., focus interviews and surveys from patients and providers). Patient-effectiveness outcomes include measures of depression, anxiety, and physical health functioning using blinded independent evaluators. Implementation outcomes include patient engagement and adherence and clinician brief cognitive behavioral therapy adoption and fidelity.
Hybrid designs are needed to advance clinical effectiveness and implementation knowledge to improve healthcare practices. The current article describes the rationale and challenges associated with the use of a hybrid design for the study of brief cognitive behavioral therapy in primary care. Although trade-offs exist between scientific control and external validity, hybrid designs are part of an emerging approach that has the potential to rapidly advance both science and practice.

Diabetes group clinics can effectively control hypertension, but data to support glycemic control is equivocal. This study evaluated the comparative effectiveness of two diabetes group clinic interventions on glycosolated hemoglobin (HbA1c) levels in primary care.
Participants (n = 87) were recruited from a diabetes registry of a single regional VA medical center to participate in an open, randomized comparative effectiveness study. Two primary care based diabetes group interventions of three months duration were compared. Empowering Patients in Care (EPIC) was a clinician-led, patient-centered group clinic consisting of four sessions on setting self-management action plans (diet, exercise, home monitoring, medications, etc.) and communicating about progress with action plans. The comparison intervention consisted of group education sessions with a diabetes educator and dietician followed by an additional visit with one’s primary care provider. HbA1c levels were compared post-intervention and at one-year follow-up.
Participants in the EPIC intervention had significantly greater improvements in HbA1c levels immediately following the active intervention (8.86 to 8.04 vs. 8.74 to 8.70, mean [SD] between-group difference 0.67±1.3, P=.03) and these differences persisted at 1 year follow-up (.59±1.4, P=.05). A repeated measures analysis using all study time points found a significant time-by-treatment interaction effect on HbA1c levels favoring the EPIC intervention (F(2,85) =3.55, P= .03). The effect of the time-by-treatment interaction appears to be partially mediated by diabetes self-efficacy (F(1,85) =10.39, P= .002).
Primary care based diabetes group clinics that include structured goal-setting approaches to self-management can significantly improve HbA1c levels post-intervention and maintain improvements for 1-year.

Delayed diagnosis of colorectal cancer (CRC) is among the most common reasons for ambulatory diagnostic malpractice claims in the United States. Our objective was to describe missed opportunities to diagnose CRC before endoscopic referral, in terms of patient characteristics, nature of clinical clues, and types of diagnostic-process breakdowns involved.
We conducted a retrospective cohort study of consecutive, newly diagnosed cases of CRC between February 1999 and June 2007 at a tertiary health-care system in Texas. Two reviewers independently evaluated the electronic record of each patient using a standardized pretested data collection instrument. Missed opportunities were defined as care episodes in which endoscopic evaluation was not initiated despite the presence of one or more clues that warrant a diagnostic workup for CRC. Predictors of missed opportunities were evaluated in logistic regression. The types of breakdowns involved in the diagnostic process were also determined and described.
Of the 513 patients with CRC who met the inclusion criteria, both reviewers agreed on the presence of at least one missed opportunity in 161 patients. Among these patients there was a mean of 4.2 missed opportunities and 5.3 clues. The most common clues were suspected or confirmed iron deficiency anemia, positive fecal occult blood test, and hematochezia. The odds of a missed opportunity were increased in patients older than 75 years (odds ratio (OR) = 2.3; 95% confidence interval (CI) 1.3–4.1) or with iron deficiency anemia (OR = 2.2; 95% CI 1.3–3.6), whereas the odds of a missed opportunity were lower in patients with abnormal flexible sigmoidoscopy (OR = 0.06; 95% CI 0.01–0.51), or imaging suspicious for CRC (OR = 0.3; 95% CI 0.1–0.9). Anemia was the clue associated with the longest time to endoscopic referral (median = 393 days). Most process breakdowns occurred in the provider–patient clinical encounter and in the follow-up of patients or abnormal diagnostic test results.
Missed opportunities to initiate workup for CRC are common despite the presence of many clues suggestive of CRC diagnosis. Future interventions are needed to reduce the process breakdowns identified.
The epidemiology and outcomes of Multiple Organ Dysfunction Syndrome (MODS) are incompletely characterized in the pediatric population due to small sample size and conflicting diagnoses of organ failure. We sought to describe the epidemiology and outcomes of early MODS in a large clinical database of PICU patients based on consensus definitions of organ failure.
Retrospective analysis of a contemporaneously collected clinical PICU database.
VPICU Performance System (VPS) database patient admissions from 1/2004-12/2005 for 35 US children’s hospitals.
We evaluated 63,285 consecutive PICU admissions from 1/2004-12/2005 in the VPS database. We excluded patients <1 month or >18 years of age, and hospitals with >10% missing values for MODS variables. We identified day 1 MODS by International Pediatric Sepsis Consensus Conference (IPSCC) criteria with day 1 laboratory and vital sign values. We evaluated functional status using Pediatric Overall Performance Category (POPC) and Pediatric Cerebral Performance Category (PCPC) scores from PICU admission and discharge.
Analysis: Student’s t-test, Χ2, Mann-Whitney rank sum, Kruskal-Wallis, linear and logistic regression.
Measurements and Main Results
We analyzed 44,693 admissions from 28 hospitals meeting inclusion criteria. Overall PICU mortality was 2.8%. We identified day 1 MODS in 18.6% of admissions. Patients with day 1 MODS had higher mortality (10.0% v. 1.2%, p<0.001), longer PICU length of stay (3.6 v. 1.3 days, p<0.001) and larger change from baseline POPC and PCPC scores at time of PICU discharge (p<0.001). Infants had the highest incidence of day 1 MODS (25.2% vs. 16.5%, p<0.001) compared to other age groups.
Using the largest clinical dataset to date and consensus definitions for organ failure, we found that children with MODS present on day one of ICU admission have worse functional outcomes, higher mortality, and longer PICU length of stay than children who do not have MODS on day one. Infants are disproportionally affected by MODS.

Health care utilization and costs among US veterans with chronic obstructive pulmonary disease (COPD) were compared with those in veterans without COPD.
A cohort of veterans with COPD was matched for age, sex, race, and index fiscal year to a cohort of veterans without COPD (controls) using data from the Veterans Integrated Service Network (VISN) 16 from 10/1/1997 to 9/30/2004. Annual total and respiratory-related health care service utilization, costs of care, comorbidities, and respiratory medication use at the time of diagnosis were assessed.
A total of 59,906 patients with COPD were identified for a 7-year period prevalence of 8.2%, or 82 per 1000 population. Patients with COPD compared with controls had significantly higher all-cause and respiratory-related inpatient and outpatient health care utilization for every parameter examined including mean numbers of physician encounters, other outpatient encounters, emergency room visits, acute inpatient discharges, total bed days of care, and percentage of patients with any emergency room visits or any acute inpatient discharge. Patients with COPD had statistically significantly higher mean outpatient, inpatient, pharmacy, and total costs than the control group. The mean Charlson comorbidity index in patients with COPD was 1 point higher than in controls (2.85 versus 1.84, P < 0.001). 60% of COPD patients were prescribed medications recommended in treatment guidelines at diagnosis.
Veterans with COPD compared with those without COPD suffer a tremendous disease burden manifested by higher rates of all-cause and respiratory-related health care utilization and costs and a high prevalence of comorbidities. Furthermore, COPD patients do not receive appropriate treatment for their disease on diagnosis.

This study aims at comparing prescription patterns between young adults and elderly with bipolar disorder who achieved a recovery status during the Systematic Treatment Enhancement Program for Bipolar Disorder (STEP-BD).
STEP-BD is a multicenter National Institute of Mental Health (NIMH)-funded project designed to evaluate the longitudinal outcome of patients with bipolar disorder. The STEP-BD study involved extensive assessment across multiple domains including demographic data, diagnosis, symptom severity, treatment and clinical status. Patients achieved “recovered” status when they experienced eight consecutive weeks without significant symptoms.
we analyzed data of all subjects who achieved a recovered status at least once in their participation.
We compared treatment regimes and doses between young participants to middle age (n=3,364), 20 to 59 years old, and older participants 60 and above (n=246).
Of the 3,615 STEP-BD participants who had a lifetime diagnosis of bipolar subtypes I or II, 67.6% (n=2442) achieved a recovered status during their participation. 78.5% (n=193) of older patients recovered compared to 66.8% of the younger cohort. On average, participants who reached a recovered status took 2.05 medications with no difference between age groups. Lithium was prescribed to 37.8% of younger patients compared to only 29.5% of older participants. The mean dosages taken by younger and older patients differed significantly only for lithium, valproate and risperidone with elderly individuals prescribed lower daily dosages. Significant reduction in lithium dosing was observed among individuals age 50 and older and among individuals 60 and older for valproate. Although valproate was more often prescribed, 42.1% of recovered bipolar elder achieved recovery with lithium alone compared to only 21.3% of the younger cohort.
This data shows recovery is achievable in the elderly though more than one medication is often needed regardless of age.

We investigated the association of process of care measures with adverse limb and systemic events in patients with peripheral arterial disease (PAD).
We conducted a retrospective cohort study of patients with PAD, as defined by an ankle-brachial index (ABI) <0.9. The index date was defined as the date, during 1995 to 1998, when the patient was seen in the Michael E. DeBakey VA Medical Center noninvasive vascular laboratory and found to have PAD. We conducted a chart review for process of care variables starting 3 years before the index date and ending at the time of the first event or the final visit (December 31, 2001), whichever occurred first. We examined the association between PAD process of care measures, including risk factor control, and prescribing of medication, with time of the patient’s first major limb event or death.
Of the 796 patients (mean age, 65 ± 9.9 years), 230 (28.9% experienced an adverse limb event (136 lower-extremity bypass, 94 lower-extremity amputation), and 354 (44.5%) died. Of the patients who died, 247 died without a preceding limb event. Glucose control was protective against death or a limb event with a hazard ratio (HR) of 0.74 (95% confidence limits [CL] 0.60, 0.91, P = 0.004). African Americans were at 2.8 (95% CL 1.7, 4.5) times the risk of Whites or Hispanics for an adverse limb event. However, this risk was no longer significant if their glucose was controlled. For process measures, the dispensing of PAD specific medication (HR 1.4, 95% CL 1.1, 1.7) was associated an increased risk for an adverse outcome.
Our data suggest that glucose control is key to reducing the risk for adverse outcomes, particularly limb events in African Americans. Certain process of care measures, as markers of disease severity and disease management, are associated with poor outcomes in patients with PAD. Further work is needed to determine the role of early disease intervention to reduce poor outcomes in patients with PAD.
