A Health System Analysis Approach to Health Outcomes in Medicare Clients With Chronic Illnesses

Since 1863, outcomes measurement efforts have provided information to health care consumers, administrators, and policymakers in assessing concerns about access, quality and costs. With a growing population of older adults with chronic illnesses, cost-cutting strategies in health delivery systems, and federal endorsement of managed care systems, researchers have begun to evaluate the impact of different delivery system organizations on health. The current study combines two areas of health services research to provide the first published hierarchical analysis of the influence of delivery system factors, and a profile of population and community characteristics and utilization factors, on perceived health outcomes of a nationally representative sample of older adult Medicare beneficiaries with various chronic illnesses. This study was designed to analyze the difference in health status outcomes across Medicare fee-for-service and health maintenance organization systems nationwide, and to explain health delivery system factors\u27 effects on outcomes. Using a recently developed health outcomes classification scheme, a newly expanded Andersen and Aday Health System Model, and hierarchical multiple regression analysis methodology, health delivery system factors were found to have a significant impact on three of four client-centered outcome measures. The results of this study suggest there are health delivery system factors affecting health outcomes of older adults with chronic illnesses. In addition, the findings imply that hierarchical regression analysis is a useful tool for explaining the unique contribution of several individual variables as well as several blocks of variables on perceived health outcomes. Information from this study can be used to monitor outcomes of health care in this vulnerable population, inform development of chronic illness-related health policy, and encourage use of high quality public data resources available for health services research

Application of a disease-specific mapping function to estimate utility gains with effective treatment of schizophrenia

BACKGROUND: Most tools for estimating utilities use clinical trial data from general health status models, such as the 36-Item Short-Form Health Survey (SF-36). A disease-specific model may be more appropriate. The objective of this study was to apply a disease-specific utility mapping function for schizophrenia to data from a large, 1-year, open-label study of long-acting risperidone and to compare its performance with an SF-36-based utility mapping function. METHODS: Patients with schizophrenia or schizoaffective disorder by DSM-IV criteria received 25, 50, or 75 mg long-acting risperidone every 2 weeks for 12 months. The Positive and Negative Syndrome Scale (PANSS) and SF-36 were used to assess efficacy and health-related quality of life. Movement disorder severity was measured using the Extrapyramidal Symptom Rating Scale (ESRS); data concerning other common adverse effects (orthostatic hypotension, weight gain) were collected. Transforms were applied to estimate utilities. RESULTS: A total of 474 patients completed the study. Long-acting risperidone treatment was associated with a utility gain of 0.051 using the disease-specific function. The estimated gain using an SF-36-based mapping function was smaller: 0.0285. Estimates of gains were only weakly correlated (r = 0.2). Because of differences in scaling and variance, the requisite sample size for a randomized trial to confirm observed effects is much smaller for the disease-specific mapping function (156 versus 672 total subjects). CONCLUSION: Application of a disease-specific mapping function was feasible. Differences in scaling and precision suggest the clinically based mapping function has greater power than the SF-36-based measure to detect differences in utility

Lessons Learned in Pilot Testing Specialty Consultations to Benefit Individuals with Lower Limb Loss

Telerehabilitation technologies enable the delivery of rehabilitation services from providers to people with disabilities as well as specialty care consultations. This article discusses the barriers experienced when planning and pilot testing a telerehabilitation multi-site specialty consultation for specialists in their medical centers, and the lessons learned. The barriers included integration and participation, coordination across organizational units, and privacy and information security. Lessons learned included the need for collaboration across multiple departments, telerehabilitation equipment back-ups, and anonymous and private communication protocols. Despite delays resulting from coordination at multiple levels of a national organization, we developed a program plan and successfully implemented a pilot test of the southeast region program.  Specialty consultation using telerehabilitation delivery methods requires identifying provider preferences for technological features. Lessons learned could inform development of outpatient telerehabilitation for patients with amputations and studies of patients and providers involved in telerehabilitation

Pain and Psychiatric Comorbidities Among Two Groups of Iraq- and Afghanistan-era Veterans

This study aimed to (1) identify the prevalence and severity of pain and psychiatric comorbidities among personnel who had been deployed during Operation Iraqi Freedom (OIF), Operation Enduring Freedom (OEF), and Operation New Dawn (OND) and (2) assess whether the Department of Veterans Affairs (VA) Polytrauma System of Care and an OIF/OEF/OND registry reflect real differences among patients. Participants (N = 359) were recruited from two VA hospitals. They completed a clinical interview, structured diagnostic interview, and self-report measures. Results indicated pain was the most common complaint, with 87% experiencing pain during the prior week and 56% reporting moderate or severe pain. Eighty percent of participants met criteria for at least one of seven assessed comorbid problems (moderate or severe pain, postconcussional disorder, posttraumatic stress disorder [PTSD], anxiety disorder, mood disorder, substance use disorder, psychosis), and 59 percent met criteria for two or more problems. PTSD and postconcussional disorder rarely occurred in the absence of pain or other comorbidities (0.3% and 0%, respectively). The Polytrauma group had more comorbid psychiatric conditions ( χ2 = 48.67, p\u3c 0.05) and reported greater severity of symptoms (p \u3c 0.05) than the Registry group. This study confirmed the high prevalence of pain and concurrent mental health problems among personnel returning from military deployment. Key words: Afghanistan, anxiety, blast injuries, chronic pain, combat disorders, comorbidities, depression, Iraq, postconcussive disorder, PTSD, sleep, substance use disorder, TBI, Veterans

The effect of North Carolina free clinics on hospitalizations for ambulatory care sensitive conditions among the uninsured

Abstract Background Free clinics are volunteer based organizations that provide health care services to low-income individuals for free or minimal cost. Communities served by a free clinic can provide ambulatory care services for uninsured individuals, reducing reliance on costly hospital admissions for ambulatory care sensitive conditions. This study examines whether free clinics in North Carolina reduce hospitalizations for ambulatory care sensitive conditions for uninsured adults. Methods The study used North Carolina hospital discharge data from 2003 to 2007, restricted to uninsured adults residing in North Carolina (N = 270,325). Prevention Quality Indicators identified hospitalizations for ambulatory care sensitive conditions. The entry of new free clinics in some counties during this time period in conjunction with county-level and year fixed effects allows the logistic regression analysis to simulate a pre/post study design. Results Discharges for ambulatory care sensitive conditions constituted 12.6% of the sample. Despite the limited coverage provided by free clinics, which serve 5.5% of the uninsured in North Carolina, uninsured adults in counties served by a free clinic had an 8.0% reduced odds of a hospitalization being for an ambulatory care sensitive condition. When the model is limited to ambulatory care sensitive conditions related to chronic conditions, the odds of a hospitalization of an uninsured adult for an ambulatory care sensitive condition in counties served by a free clinic is reduced by 9.0%. Conclusion Free clinics are effective providers of primary care services for uninsured individuals, particularly for those with chronic conditions. To enhance this impact by increasing free clinics’ reach, state and local policy makers should support and encourage development of free clinics in high need areas

A qualitative study of implementation and adaptations to Progressive Tinnitus Management (PTM) delivery

<div><p>Background</p><p>Tinnitus is a common condition, especially prevalent among military Veterans. Progressive Tinnitus Management (PTM) is an interdisciplinary, structured, stepped-care approach to providing clinical services, including teaching coping skills, to people bothered by tinnitus. PTM has been shown to be effective at reducing functional distress, but implementation of the intervention outside of a research setting has not been studied, even though dissemination is underway within the Veterans Health Administration (VHA) system in the United States. This study was designed to address a gap in knowledge of PTM clinical implementation to date, with a focus on factors facilitating or hindering implementation in VHA audiology and mental health clinic contexts, and whether implementing sites had developed intervention adaptations.</p><p>Methods</p><p>Qualitative interviews were conducted with 21 audiology and mental health clinicians and service chiefs across a regional service network. Interviews were transcribed and coded using a hybrid inductive-deductive analytic approach guided by existing implementation research frameworks and then iteratively developed for emergent themes.</p><p>Results</p><p>PTM prioritization was rare overall, with providers across disciplines challenged by lack of capacity for implementation, but with differences by discipline in challenges to prioritization. Where PTM was prioritized and delivered, this was facilitated by perception of unique value, provider’s own experience of tinnitus, observation/experience with PTM delivery, intervention fit with provider’s skills, and an environment with supportive leadership and adaptive reserve. PTM was frequently adapted to local contexts to address delivery challenges and diversify patient options. Adaptations included shifting from group to individual formats, reducing or combining sessions, and employing novel therapeutic approaches.</p><p>Conclusions</p><p>Existing adaptations highlight the need to better understand mechanisms underlying PTM’s effectiveness, and research on the impact of adaptations on patient outcomes is an important next step. Prioritization of PTM is a key barrier to the scale up and spread of this evidence-based intervention. Developing clinician champions may facilitate dissemination, especially if accompanied by signals of systemic prioritization. Novel approaches exposing clinicians and administrators to PTM may identify and develop clinical champions. Acknowledging the potential for PTM adaptations may make delivery more feasible in the context of existing system constraints and priorities.</p></div

Validity of Center for Epidemiologic Studies Depression (CES-D) Scale in a Sample of Iraq and Afghanistan Veterans

Objectives: Optimal depression screening necessitates measurement tools that are valid across varied populations and in the presence of comorbidities. Methods: This study assessed the test properties of two versions of the Center for Epidemiologic Studies Depression scale against psychiatric diagnoses established by the Mini International Neuropsychiatric Interview among a clinical sample of US Veterans deployed during Operations Enduring Freedom, Iraqi Freedom, and New Dawn. Participants (N = 359) recruited from two Department of Veterans Affairs hospitals completed a clinical interview, structured diagnostic interview, and self-reported measures. Results: Based on diagnostic interview and the Diagnostic and Statistical Manual of Mental Disorders 4th Edition criteria, 29.5% of the sample met diagnostic criteria for major depressive disorder and 26.5% met diagnostic criteria for post-traumatic stress disorder. Both Center for Epidemiologic Studies Depression-20 and Center for Epidemiologic Studies Depression-10 scales performed well and almost identically against the Mini International Neuropsychiatric Interview-major depressive disorder in identifying Veterans with major depressive disorder (Center for Epidemiologic Studies Depression-20 area under the Receiver Operating Characteristic curve 91%; Center for Epidemiologic Studies Depression-10 area under the ROC curve 90%). Overall, higher cut points for the Center for Epidemiologic Studies Depression scales performed better in correctly identifying true positives and true negatives for major depressive disorder (Center for Epidemiologic Studies Depression-20 cut point 18+ sensitivity 92% specificity 72%; Center for Epidemiologic Studies Depression-10 cut point 10+ sensitivity 92% specificity 69%). Conclusions: The specificity of the Center for Epidemiologic Studies Depression scales was poor among Veterans with co-occurring post-traumatic stress disorder (13% and 16%). Veterans with post-traumatic stress disorder who have a positive depression screen should have a more thorough assessment of mental health symptoms and comorbidities, rather than immediate diagnosis of and treatment for depression
