Comparing Quality of Care in Veterans Affairs and Non-Veterans Affairs Settings.

BACKGROUND: Congress, veterans' groups, and the press have expressed concerns that access to care and quality of care in Department of Veterans Affairs (VA) settings are inferior to access and quality in non-VA settings. OBJECTIVE: To assess quality of outpatient and inpatient care in VA at the national level and facility level and to compare performance between VA and non-VA settings using recent performance measure data. MAIN MEASURES: We assessed Patient Safety Indicators (PSIs), 30-day risk-standardized mortality and readmission measures, and ORYX measures for inpatient safety and effectiveness; Healthcare Effectiveness Data and Information Set (HEDIS®) measures for outpatient effectiveness; and Consumer Assessment of Healthcare Providers and Systems Hospital Survey (HCAHPS) and Survey of Healthcare Experiences of Patients (SHEP) survey measures for inpatient patient-centeredness. For inpatient care, we used propensity score matching to identify a subset of non-VA hospitals that were comparable to VA hospitals. KEY RESULTS: VA hospitals performed on average the same as or significantly better than non-VA hospitals on all six measures of inpatient safety, all three inpatient mortality measures, and 12 inpatient effectiveness measures, but significantly worse than non-VA hospitals on three readmission measures and two effectiveness measures. The performance of VA facilities was significantly better than commercial HMOs and Medicaid HMOs for all 16 outpatient effectiveness measures and for Medicare HMOs, it was significantly better for 14 measures and did not differ for two measures. High variation across VA facilities in the performance of some quality measures was observed, although variation was even greater among non-VA facilities. CONCLUSIONS: The VA system performed similarly or better than the non-VA system on most of the nationally recognized measures of inpatient and outpatient care quality, but high variation across VA facilities indicates a need for targeted quality improvement.

Quality of Care for PTSD and Depression in the Military Health System: Final Report.

The U.S. Department of Defense (DoD) strives to maintain a physically and psychologically healthy, mission-ready force, and the care provided by the Military Health System (MHS) is critical to meeting this goal. Attention has been directed to ensuring the quality and availability of programs and services for posttraumatic stress disorder (PTSD) and depression. This study is a comprehensive assessment of the quality of care delivered by the MHS in 2013-2014 for over 38,000 active-component service members with PTSD or depression. The assessment includes performance on 30 quality measures to evaluate the receipt of recommended assessments and treatments. These measures draw on multiple data sources including administrative encounter data, medical record review data, and patient self-reported outcome monitoring data. The assessment identified strengths and areas for improvement for the MHS. In particular, the MHS excels at screening for suicide risk and substance use, but rates of appropriate follow-up for service members with suicide risk are lower. Most service members received at least some psychotherapy, but less than half of psychotherapy delivered was evidence-based. In analyses focused on Army soldiers, outcome monitoring increased notably over time, yet preliminary analyses suggest that more work is needed to ensure that services are effective in reducing symptoms. When comparing performance between 2012-2013 and 2013-2014, most measures demonstrated slight improvement, but targeted efforts will be needed to support further improvements. RAND provides recommendations for strategies to improve the quality of care delivered for these conditions.

Resources and Capabilities of the Department of Veterans Affairs to Provide Timely and Accessible Care to Veterans.

The Veterans Access, Choice, and Accountability Act of 2014 addressed the need for access to timely, high-quality health care for veterans. Section 201 of the legislation called for an independent assessment of various aspects of veterans' health care. The RAND Corporation was tasked with an assessment of the Department of Veterans Affairs (VA) current and projected health care capabilities and resources. An examination of data from a variety of sources, along with a survey of VA medical facility leaders, revealed the breadth and depth of VA resources and capabilities: fiscal resources, workforce and human resources, physical infrastructure, interorganizational relationships, and information resources. The assessment identified barriers to the effective use of these resources and capabilities. Analysis of data on access to VA care and the quality of that care showed that almost all veterans live within 40 miles of a VA health facility, but fewer have access to VA specialty care. Veterans usually receive care within 14 days of their desired appointment date, but wait times vary considerably across VA facilities. VA has long played a national leadership role in measuring the quality of health care. The assessment showed that VA health care quality was as good or better on most measures compared with other health systems, but quality performance lagged at some VA facilities. VA will require more resources and capabilities to meet a projected increase in veterans' demand for VA care over the next five years. Options for increasing capacity include accelerated hiring, full nurse practice authority, and expanded use of telehealth.

Quality of Care for PTSD and Depression in the Military Health System: Phase I Report.

The U.S. Department of Defense (DoD) strives to maintain a physically and psychologically healthy, mission-ready force, and the care provided by the Military Health System (MHS) is critical to meeting this goal. Given the rates of posttraumatic stress disorder (PTSD) and depression among U.S. service members, attention has been directed to ensuring the quality and availability of programs and services targeting these and other psychological health (PH) conditions. Understanding the current quality of care for PTSD and depression is an important step toward improving care across the MHS. To help determine whether service members with PTSD or depression are receiving evidence-based care and whether there are disparities in care quality by branch of service, geographic region, and service member characteristics (e.g., gender, age, pay grade, race/ethnicity, deployment history), DoD's Defense Centers of Excellence for Psychological Health and Traumatic Brain Injury (DCoE) asked the RAND Corporation to conduct a review of the administrative data of service members diagnosed with PTSD or depression and to recommend areas on which the MHS could focus its efforts to continuously improve the quality of care provided to all service members. This study characterizes care for service members seen by MHS for diagnoses of PTSD and/or depression and finds that while the MHS performs well in ensuring outpatient follow-up following psychiatric hospitalization, providing sufficient psychotherapy and medication management needs to be improved. Further, quality of care for PTSD and depression varied by service branch, TRICARE region, and service member characteristics, suggesting the need to ensure that all service members receive high-quality care.

Improving Care for Chronic Conditions: Current Practices and Future Trends in Health Plan Programs.

The need for better management of chronic conditions is urgent. About 141 million people in the United States were living with one or more chronic conditions in 2010, and this number is projected to increase to 171 million by 2030. To address this challenge, many health plans have piloted and rolled out innovative approaches to improving care for their members with chronic conditions. This article documents the current range of chronic care management services, identifies best practices and industry trends, and examines factors in the plans' operating environment that limit their ability to optimize chronic care programs. The authors conducted telephone surveys with a representative sample of health plans and made in-depth case studies of six plans. All plans in the sample provide a wide range of products and services around chronic care, including wellness/lifestyle management programs for healthy members, disease management for members with common chronic conditions, and case management for high-risk members regardless of their underlying condition. Health plans view these programs as a "win-win" situation and believe that they improve care for their most vulnerable members and reduce cost of coverage. Plans are making their existing programs more patient-centric and are integrating disease and case management, and sometimes lifestyle management and behavioral health, into a consolidated chronic care management program, believing that this will increase patient engagement and prevent duplication of services and missed opportunities.

Measuring the Quality of Care for Psychological Health Conditions in the Military Health System: Candidate Quality Measures for Posttraumatic Stress Disorder and Major Depressive Disorder.

In recent years, the number of U.S. service members treated for psychological health conditions has increased substantially. In particular, at least two psychological health conditions-posttraumatic stress disorder (PTSD) and major depressive disorder (MDD)-have become more common, with prevalence estimates up to 20 percent for PTSD and 37 percent for MDD. Delivering quality care to service members with these conditions is a high-priority goal for the military health system (MHS). Meeting this goal requires understanding the extent to which the care the MHS provides is consistent with evidence-based clinical practice guidelines and its own standards for quality. To better understand these issues, RAND Corporation researchers developed a framework to identify and classify a set of measures for monitoring the quality of care provided by the MHS for PTSD and MDD. The goal of this project was to identify, develop, and describe a set of candidate quality measures to assess care for PTSD and MDD. To accomplish this goal, the authors performed two tasks: (1) developed a conceptual framework for assessing the quality of care for psychological health conditions and (2) identified a candidate set of measures for monitoring, assessing, and improving the quality of care for PTSD and MDD. This article describes their research approach and the candidate measure sets for PTSD and MDD that they identified. The current task did not include implementation planning but provides the foundation for future RAND work to pilot a subset of these measures.

Evaluation of a center of excellence program for spine surgery.

BACKGROUND: The Centers for Medicare and Medicaid Services and many private health plans are encouraging patients to seek orthopedic care at hospitals designated as centers of excellence. No evaluations have been conducted to compare patient outcomes and costs at centers of excellence versus other hospitals. The objective of our study was to assess whether hospitals designated as spine surgery centers of excellence by a group of over 25 health plans provided higher quality care. METHODS: Claims representing approximately 54 million commercially insured individuals were used to identify individuals aged 18-64 years with 1 of 3 types of spine surgery in 2007-2009: 1-level or 2-level cervical fusion (referred to as cervical simple fusion), 1-level or 2-level lumbar fusion (referred to as lumbar simple fusion), or lumbar discectomy and/or decompression without fusion. The primary outcomes were any complication (7 complications were captured) and 30-day readmission. The multivariate models controlled for differences in age, sex, and comorbidities between the 2 sets of hospitals. RESULTS: A total of 29,295 cervical simple fusions, 27,214 lumbar simple fusions, and 28,911 lumbar discectomy/decompressions were identified, of which 42%, 42%, and 47%, respectively, were performed at a hospital designated as a spine surgery center of excellence. Designated hospitals had a larger number of beds and were more likely to be an academic center. Across the 3 types of spine surgery (cervical fusions, lumbar fusions, or lumbar discectomies/decompressions), there was no difference in the composite complication rate [OR 0.90 (95% CI, 0.72-1.12); OR 0.98 (95% CI, 0.85-1.13); OR 0.95 (95% CI, 0.82-1.07), respectively] or readmission rate [OR 1.03 (95% CI, 0.87-1.21); OR 1.01 (95% CI, 0.89-1.13); OR 0.91 (95%, CI 0.79-1.04), respectively] at designated hospitals compared with other hospitals. CONCLUSIONS: On average, spine surgery centers of excellence had similar complication rates and readmission rates compared with other hospitals. These results highlight the importance of empirical evaluations of centers of excellence programs.

Evaluation of centers of excellence program for knee and hip replacement.

BACKGROUND: Medicare and private plans are encouraging individuals to seek care at hospitals that are designated as centers of excellence. Few evaluations of such programs have been conducted. This study examines a large national initiative that designated hospitals as centers of excellence for knee and hip replacement. OBJECTIVE: Comparison of outcomes and costs associated with knee and hip replacement at designated hospitals and other hospitals. RESEARCH DESIGN: Retrospective claims analysis of approximately 54 million enrollees. STUDY POPULATION: Individuals with insurance from one of the sponsors of this centers of excellence program who underwent a primary knee or hip replacement in 2007-2009. OUTCOMES: Primary outcomes were any complication within 30 days of discharge and costs within 90 days after the procedure. RESULTS: A total of 80,931 patients had a knee replacement and 39,532 patients had a hip replacement of which 52.2% and 56.5%, respectively, were performed at a designated hospital. Designated hospitals had a larger number of beds and were more likely to be an academic center. Patients with a knee replacement at designated hospitals did not have a statistically significantly lower overall complication rate with an odds ratio of 0.90 (P=0.08). Patients with hip replacement treated at designated hospitals had a statistically significant lower risk of complications with an odds ratio of 0.80 (P=0.002). There was no significant difference in 90-day costs for either procedure. CONCLUSIONS: Hospitals designated as joint replacement centers of excellence had lower rates of complications for hip replacement, but there was no statistically significant difference for knee replacement. It is important to validate the criteria used to designate centers of excellence.

Disabled Medicare beneficiaries by dual eligible status: California, 1996-2001.

This highlight describes the characteristics and inpatient utilization of under age 65 disabled California Medicare beneficiaries by dual eligible status (i.e., Medicaid State buy-in coverage or not). More disabled dually eligible beneficiaries are younger, non-White, and in fee-for-service (FFS) than non-dually eligible beneficiaries. Disabled dually eligible beneficiaries experienced consistently higher hospitalization rates and average length of stay (LOS) than nondually eligible beneficiaries from 1996 to 2001. Inpatient days remain higher among dually eligible beneficiaries when stratified by the system of care, age, sex, or race. In addition, the hospitalization rate of disabled dually eligible beneficiaries was higher for most diagnoses, but how much higher varied by condition.

Effect of disease management on prescription drug treatment: what is the right quality measure?

Measures of medication adherence have become common parameters with which disease management (DM) programs are being evaluated, leading to the question of how this concept should be measured in the particular context of a DM intervention. We hypothesize that DM improves adherence to prescriptions more than the rate with which prescriptions are being filled. We used health plan claims data to construct 13 common measures of medication adherence for five chronic conditions. The measures were operationalized in three different ways: the Prescription Fill Rate (PFR), which requires only one prescription; the Medication Possession Ratio (MPR), which requires a supply that covers at least 80% of the year; and the Length of Gap (LOG), which requires no gap greater than 30 days between prescriptions. We compared results from a baseline year to results during the first year of a DM program. Changes in adherence were quite small in the first year of the intervention, with no changes greater than six percentage points. In the intervention year, three measures showed a significant increase based on all three operational definitions, but two measures paradoxically decreased based on the PFR. For both, the MPR and the LOG suggested either no change or significant improvement. None of the MPR and LOG measures pointed toward significantly lower compliance in the intervention year. Different ways to operationalize the concept of medication adherence can lead to fundamentally different conclusions. While more complex, MPR- and LOG-based measures could be more appropriate for DM evaluation. Our initial results, however, need to be confirmed by data covering longer term follow-up.

The effect of medicare health maintenance organizations on hospitalization rates for ambulatory care-sensitive conditions.

OBJECTIVE: The objective of this study was to estimate the effect of Medicare Health Maintenance Organization (HMO) enrollment on hospitalization rates and total inpatient days for ambulatory care-sensitive conditions (ACSCs) after controlling for selection. RESEARCH DESIGN: Simultaneous equations using a discrete factor selection model are used to estimate the probability of HMO enrollment, hospitalization rates, and total inpatient days for ACSCs. SUBJECTS: Enrollment data on Medicare beneficiaries in California were linked to hospital discharge data from the California Office of Statewide Health Planning and Development for January through December 1996. The following beneficiaries were excluded: 1) end-stage renal disease, 2) under 65 years of age, 3) not covered by both Medicare Part A and Part B, 4) switched between HMOs and fee-for-service (FFS), and 5) switched between HMOs. The sample was stratified by age, gender, race, county, disability, Medicaid eligibility, HMO status, and death. A 2% random sample from the 4 California counties with the largest Medicare enrollment yielded 10,448 HMO enrollees and 11,803 FFS beneficiaries. RESULTS: Using a discrete factor selection model, we estimated the rate of ACSC hospitalizations among FFS beneficiaries would decline from 51.2 to 44.2 per 1000 if all FFS beneficiaries joined an HMO. Similarly, the mean total inpatient days for ACSC hospitalizations would be reduced from 7.5 days to 5.1 days if all FFS beneficiaries joined an HMO. CONCLUSIONS: After controlling for selection, Medicare HMO enrollees have lower hospitalization rates and fewer total inpatient days for 15 ACSCs than Medicare FFS beneficiaries. These findings suggest selection of healthier beneficiaries into HMOs does not completely explain their lower rates of ACSC hospitalization.

Direct medical costs attributable to acute myocardial infarction and ischemic stroke in cohorts with atherosclerotic conditions.

BACKGROUND: The cost of acute ischemic events in persons with established atherosclerotic conditions is unknown. METHODS: The direct medical costs attributable to secondary acute myocardial infarction (AMI) or ischemic stroke among persons with established atherosclerotic conditions were estimated from 1995-1998 data on 1,143 patients enrolled in US managed care plans. RESULTS: The average 180-day costs attributable to secondary AMI or stroke were estimated as USD 19,056 in the AMI cohort having a private insurance (commercial; n = 344), USD 16,845 in the AMI cohort having government insurance (Medicare, age >/=65 years; n = 200), USD 10,267 for stroke commercial (n = 108), USD 16,280 for stroke Medicare (n = 113), USD 15,224 for peripheral arterial disease commercial (n = 170), and USD 15,182 for peripheral arterial disease Medicare (n = 208). CONCLUSION: These estimates can be used to study the cost-effectiveness of interventions proven to reduce these secondary events.

Inpatient utilization by dual Medicare-Medicaid eligibles in Medicare risk HMOs and fee for service, California, 1991-1996.

Inpatient use among dual Medicare-Medicaid eligible beneficiaries in California Medicare HMOs and fee-for-service plans from 1991 to 1996 was compared, using a unique dataset that links Medicare enrollment data to inpatient discharge data. Dual eligibles in HMOs were found to have lower discharge rates, shorter lengths of stay, and fewer inpatient days than dual eligibles in the traditional fee-for-service system. Both, however, had higher discharge rates and inpatient days than non-dual-eligible beneficiaries. The results are consistent with previous findings documenting the high cost of dual eligibles, with the lower use in HMOs likely the result of differences in beneficiary characteristics and delivery of care between systems.

The quality of medical care provided to vulnerable community-dwelling older patients.

BACKGROUND: Many people 65 years of age and older are at risk for functional decline and death. However, the resource-intensive medical care provided to this group has received little evaluation. Previous studies have focused on general medical conditions aimed at prolonging life, not on geriatric issues important for quality of life. OBJECTIVE: To measure the quality of medical care provided to vulnerable elders by evaluating the process of care using Assessing Care of Vulnerable Elders quality indicators (QIs). DESIGN: Observational cohort study. SETTING: Managed care organizations in the northeastern and southwestern United States. PATIENTS: Vulnerable older patients identified by a brief interview from a random sample of community-dwelling adults 65 years of age or older who were enrolled in 2 managed care organizations and received care between July 1998 and July 1999. MEASUREMENTS: Percentage of 207 QIs passed, overall and for 22 target conditions; by domain of care (prevention, diagnosis, treatment, and follow-up); and by general medical condition (for example, diabetes and heart failure) or geriatric condition (for example, falls and incontinence). RESULTS: Patients were eligible for 10 711 QIs, of which 55% were passed. There was no overall difference between managed care organizations. Wide variation in adherence was found among conditions, ranging from 9% for end-of-life care to 82% for stroke care. More treatment QIs were completed (81%) compared with other domains (follow-up, 63%; diagnosis, 46%; and prevention, 43%). Adherence to QIs was lower for geriatric conditions than for general medical conditions (31% vs. 52%; P < 0.001). CONCLUSIONS: Care for vulnerable elders falls short of acceptable levels for a wide variety of conditions. Care for geriatric conditions is much less optimal than care for general medical conditions.

Occurrence of secondary ischemic events among persons with atherosclerotic vascular disease.

BACKGROUND AND PURPOSE: Few data exist for large managed care populations on the occurrence of subsequent acute ischemic events in persons with established atherosclerotic vascular disease. We estimated the occurrence of secondary stroke, acute myocardial infarction (AMI), and vascular deaths among 2 large, managed care samples. METHODS: With the use of International Classification of Diseases, Ninth Revision, Clinical Modification codes, patients aged > or =40 years and with stroke, AMI, or peripheral arterial disease (PAD) were identified from administrative data of UnitedHealthcare plans during 1995-1998. Stroke, AMI, and PAD cohorts were identified within a commercial insurance sample and a Medicare sample. Cumulative occurrences of subsequent stroke, AMI, or vascular death were estimated by survival analysis. RESULTS: In the stroke commercial cohort (n=1631; mean age, 62.1 years), cumulative occurrence of subsequent events was 4.2%, 6.5%, 9.8%, and 11.8% at 0.5, 1, 2, and 3 years, respectively; cumulative secondary event occurrence in the AMI commercial cohort (n=6458; mean age, 56.0 years) was 3.5%, 4.8%, 7.3%, and 8.5% and in the PAD commercial cohort (n=5813; mean age, 59.2 years) was 1.5%, 2.8%, 4.8%, and 6.5%, respectively. Cumulative secondary event occurrences were even higher in stroke (n=1518; mean age, 79.5 years), AMI (n=2197; mean age, 76.2 years), and PAD (n=5033; mean age, 76.6 years) cohorts of the Medicare sample: 18.1%, 17.0%, and 8.7%, respectively, at 3 years. More than 75% of each stroke cohort's secondary events were strokes; more than 75% of each AMI cohort's secondary events were AMIs. Of the PAD cohorts' secondary events, 27% to 39% were strokes, 48% to 57% were AMIs, and 13% to 16% were vascular deaths. CONCLUSIONS: Among these managed care enrollees with existing atherosclerotic vascular disease, subsequent ischemic events represent a significant symptomatic disease burden. Given these findings, it is very important to determine whether secondary prevention strategies are being effectively used to manage patients with diagnosed atherosclerosis.
