Computer-based guideline implementation systems: a systematic review of functionality and effectiveness.

In this systematic review, the authors analyze the functionality provided by recent computer-based guideline implementation systems and characterize the effectiveness of the systems. Twenty-five studies published between 1992 and January 1998 were identified. Articles were included if the authors indicated an intent to implement guideline recommendations for clinicians and if the effectiveness of the system was evaluated. Provision of eight information management services and effects on guideline adherence, documentation, user satisfaction, and patient outcome were noted. All systems provided patient-specific recommendations. In 19, recommendations were available concurrently with care. Explanation services were described for nine systems. Nine systems allowed interactive documentation, and 17 produced paper-based output. Communication services were present most often in systems integrated with electronic medical records. Registration, calculation, and aggregation services were infrequently reported. There were 10 controlled trials (9 randomized) and 10 time-series correlational studies. Guideline adherence improved in 14 of 18 systems in which it was measured. Documentation improved in 4 of 4 studies.

Increased Risk of Fragility Fractures among HIV Infected Compared to Uninfected Male Veterans

Background HIV infection has been associated with an increased risk of fragility fracture. We explored whether or not this increased risk persisted in HIV infected and uninfected men when controlling for traditional fragility fracture risk factors. Methodology/Principal Findings Cox regression models were used to assess the association of HIV infection with the risk for incident hip, vertebral, or upper arm fracture in male Veterans enrolled in the Veterans Aging Cohort Study Virtual Cohort (VACS-VC). We calculated adjusted hazard ratios comparing HIV status and controlling for demographics and other established risk factors. The sample consisted of 119,318 men, 33% of whom were HIV infected (34% aged 50 years or older at baseline, and 55% black or Hispanic). Median body mass index (BMI) was lower in HIV infected compared with uninfected men (25 vs. 28 kg/m2; p<0.0001). Unadjusted risk for fracture was higher among HIV infected compared with uninfected men [HR: 1.32 (95% CI: 1.20, 1.47)]. After adjusting for demographics, comorbid disease, smoking and alcohol abuse, HIV infection remained associated with an increased fracture risk [HR: 1.24 (95% CI: 1.11, 1.39)]. However, adjusting for BMI attenuated this association [HR: 1.10 (95% CI: 0.97, 1.25)]. The only HIV-specific factor associated with fragility fracture was current protease inhibitor use [HR: 1.41 (95% CI: 1.16, 1.70)]. Conclusions/Significance HIV infection is associated with fragility fracture risk. This risk is attenuated by BMI.

Gender Differences in Rates of Depression, PTSD, Pain, Obesity, and Military Sexual Trauma Among Connecticut War Veterans of Iraq and Afghanistan

PURPOSE The current wars in Iraq and Afghanistan have led to an increasing number of female veterans seeking medical and mental healthcare in the Department of Veterans Affairs (VA) healthcare system. To better understand gender differences in healthcare needs among recently returned veterans, we examined the prevalence of positive screenings for depression, posttraumatic stress disorder (PTSD), military sexual trauma (MST), obesity, and chronic pain among female and male veterans of Operation Enduring Freedom/Operation Iraqi Freedom (OEF/OIF) receiving care at the VA Connecticut Healthcare System. METHODS We performed a retrospective, cross-sectional data analysis of OEF/OIF veterans at VA Connecticut who received services in either Primary Care or the Womens Health Clinic between 2001 and 2006. RESULTS In this study, 1129 electronic medical records (1032 men, 197 women) were examined. Female veterans were more likely to screen positive for MST (14% vs. 1%, p < 0.001) and depression (48% vs. 39%, p = 0.01) and less likely to screen positive for PTSD (21% vs. 33%, p = 0.002). There was no significant gender difference in clinically significant pain scores. Men were more likely than women to have body mass index (BMI) >30 kg/m(2) (21% vs. 13%, p = 0.008). CONCLUSIONS These results suggest that important gender differences exist in the prevalence of positive screenings for MST, depression, obesity, and PTSD. As the VA continues to review and improve its services for women veterans, clinicians, researchers, and senior leaders should consider innovative ways to ensure that female veterans receive the health services they need within the VA system.

Women at war: understanding how women veterans cope with combat and military sexual trauma.

The wars in Iraq (Operation Iraqi Freedom, OIF) and Afghanistan (Operation Enduring Freedom, OEF) have engendered a growing population of US female veterans, with women now comprising 15% of active US duty military personnel. Women serving in the military come under direct fire and experience combat-related injuries and trauma, and are also often subject to in-service sexual assaults and sexual harassment. However, little is known regarding how women veterans cope with these combat and military sexual trauma experiences once they return from deployment. To better understand their experiences, we conducted semi-structured interviews with nineteen OEF/OIF women veterans between January-November 2009. Women veterans identified stressful military experiences and post-deployment reintegration problems as major stressors. Stressful military experiences included combat experiences, military sexual trauma, and separation from family. Women had varying abilities to address and manage stressors, and employed various cognitive and behavioral coping resources and processes to manage their stress.

Safety of Sports for Athletes With Implantable Cardioverter-Defibrillators Results of a Prospective, Multinational Registry

Background— The risks of sports participation for implantable cardioverter-defibrillator (ICD) patients are unknown. Methods and Results— Athletes with ICDs (age, 10–60 years) participating in organized (n=328) or high-risk (n=44) sports were recruited. Sports-related and clinical data were obtained by phone interview and medical records. Follow-up occurred every 6 months. ICD shock data and clinical outcomes were adjudicated by 2 electrophysiologists. Median age was 33 years (89 subjects <20 years of age); 33% were female. Sixty were competitive athletes (varsity/junior varsity/traveling team). A pre-ICD history of ventricular arrhythmia was present in 42%. Running, basketball, and soccer were the most common sports. Over a median 31-month (interquartile range, 21–46 months) follow-up, there were no occurrences of either primary end point—death or resuscitated arrest or arrhythmia- or shock-related injury—during sports. There were 49 shocks in 37 participants (10% of study population) during competition/practice, 39 shocks in 29 participants (8%) during other physical activity, and 33 shocks in 24 participants (6%) at rest. In 8 ventricular arrhythmia episodes (device defined), multiple shocks were received: 1 at rest, 4 during competition/practice, and 3 during other physical activity. Ultimately, the ICD terminated all episodes. Freedom from lead malfunction was 97% at 5 years (from implantation) and 90% at 10 years. Conclusions— Many athletes with ICDs can engage in vigorous and competitive sports without physical injury or failure to terminate the arrhythmia despite the occurrence of both inappropriate and appropriate shocks. These data provide a basis for more informed physician and patient decision making in terms of sports participation for athletes with ICDs.Background— The risks of sports participation for implantable cardioverter-defibrillator (ICD) patients are unknown.

UMLS concept indexing for production databases: a feasibility study.

OBJECTIVES To explore the feasibility of using the National Library of Medicines Unified Medical Language System (UMLS) Metathesaurus as the basis for a computational strategy to identify concepts in medical narrative text preparatory to indexing. To quantitatively evaluate this strategy in terms of true positives, false positives (spuriously identified concepts) and false negatives (concepts missed by the identification process). METHODS Using the 1999 UMLS Metathesaurus, the authors processed a training set of 100 documents (50 discharge summaries, 50 surgical notes) with a concept-identification program, whose output was manually analyzed. They flagged concepts that were erroneously identified and added new concepts that were not identified by the program, recording the reason for failure in such cases. After several refinements to both their algorithm and the UMLS subset on which it operated, they deployed the program on a test set of 24 documents (12 of each kind). RESULTS Of 8,745 matches in the training set, 7,227 (82.6 percent ) were true positives, whereas of 1,701 matches in the test set, 1, 298 (76.3 percent) were true positives. Matches other than true positive indicated potential problems in production-mode concept indexing. Examples of causes of problems were redundant concepts in the UMLS, homonyms, acronyms, abbreviations and elisions, concepts that were missing from the UMLS, proper names, and spelling errors. CONCLUSIONS The error rate was too high for concept indexing to be the only production-mode means of preprocessing medical narrative. Considerable curation needs to be performed to define a UMLS subset that is suitable for concept matching.

A Guideline Implementation System Using Handheld Computers for Office Management of Asthma: Effects on Adherence and Patient Outcomes

Objective. To evaluate effects on the process and outcomes of care brought about by use of a handheld, computer-based system that implements the American Academy of Pediatrics guideline on office management of asthma exacerbations. Design. A before–after trial with randomly selected, office-based Connecticut pediatricians. In both the control and intervention phases, physicians collected data from 10 patient encounters for acute asthma exacerbations. During the intervention phase, the computer provided for structured encounter documentation and offered recommendations based on the guideline of the American Academy of Pediatrics. Patients were contacted by telephone 7 to 14 days after the visit to assess outcomes. Results. Nine study-physicians enrolled 91 patients in the control phase and 74 in the intervention phase. Follow-up information was available for 93% of encounters. Use of the intervention was associated with increased mean frequency/visit of: 1) measurements of peak expiratory flow rate (2.18 vs 1.57) and oxygen saturation (1.12 vs .42), and 2) administration of nebulized β2-agonists (1.25 vs .71). Visits in the intervention phase lasted longer and fees were higher (

103.11). There were no significant differences in immediate disposition or subsequent emergency department visits, hospitalizations, missed school, or caretakers missed work during the 7 days post visit. Conclusion. Use of handheld computers that provide guideline-based decision support was associated with increased physician adherence to guideline recommendations; however, visits were prolonged, fees were higher, and no improvement could be demonstrated with regard to the observed intermediate-term patient outcomes. Guideline implementers (and users) should be cautious about putting unvalidated recommendations into practice.

The Burden of Illness in the First Year Home: Do Male and Female VA Users Differ in Health Conditions and Healthcare Utilization

BackgroundWe sought to describe sex differences in the prevalence of painful musculoskeletal conditions in men and women Veterans after deployment in Operation Enduring Freedom (Afghanistan) and Operation Iraqi Freedom (Iraq) (OEF-OIF). MethodsThis is an observational study using Veterans Affairs (VA) administrative and clinical databases of OEF-OIF Veterans who had enrolled in and used VA care. The prevalence of back problems, musculoskeletal conditions, and joint disorders was determined at years 1 through 7 after deployment for female and male Veterans using ICD-9 code groupings for these conditions. ResultsFemale Veterans were younger (mean age 29 vs. 30, P<0.0001), more likely to be African American (26% vs. 13%, P<0.0001), and less likely to be married (34% vs. 47%, P<0.0001). For both female and male Veterans, the prevalence of painful musculoskeletal conditions increased each year after deployment. After adjustment for significant demographic differences, women were more likely than men to have back problems [year 1 odds ratio (OR) 1.06 (1.01, 1.11)], musculoskeletal problems [year 1 OR 1.32 (1.24, 1.40)], and joint problems [year 1 OR 1.36 (1.21, 1.53)] and the odds of having these conditions increased each year for women compared with men in years 1 to 7 after deployment. DiscussionTo provide quality care to female Veterans, the VA must understand the impact of deployment on womens health. Our findings provide an important picture of the increasing prevalence of musculoskeletal conditions in the female Veteran population and highlight the importance of the VA targeting treatment programs that focus on issues of particular importance to women with musculoskeletal pain.
