Analysis of Therapeutic Inertia and Race and Ethnicity in the Systolic Blood Pressure Intervention Trial: A Secondary Analysis of a Randomized Clinical Trial.

Importance: Therapeutic inertia may contribute to racial and ethnic differences in blood pressure (BP) control. Objective: To determine the association between race and ethnicity and therapeutic inertia in the Systolic Blood Pressure Intervention Trial (SPRINT). Design, Setting, and Participants: This cross-sectional study was a secondary analysis of data from SPRINT, a randomized clinical trial comparing intensive (<120 mm Hg) vs standard (<140 mm Hg) systolic BP treatment goals. Participants were enrolled between November 8, 2010, and March 15, 2013, with a median follow-up 3.26 years. Participants included adults aged 50 years or older at high risk for cardiovascular disease but without diabetes, previous stroke, or heart failure. The present analysis was restricted to participant visits with measured BP above the target goal. Analyses for the present study were performed in from October 2020 through March 2021. Exposures: Self-reported race and ethnicity, mutually exclusively categorized into groups of Hispanic, non-Hispanic Black, or non-Hispanic White participants. Main Outcomes and Measures: Therapeutic inertia, defined as no antihypertensive medication intensification at each study visit where the BP was above target goal. The association between self-reported race and ethnicity and therapeutic inertia was estimated using generalized estimating equations and stratified by treatment group. Antihypertensive medication use was assessed with pill bottle inventories at each visit. Blood pressure was measured using an automated device. Results: A total of 8556 participants, including 4141 in the standard group (22 844 participant-visits; median age, 67.0 years [IQR, 61.0-76.0 years]; 1467 women [35.4%]) and 4415 in the intensive group (35 453 participant-visits; median age, 67.0 years [IQR, 61.0-76.0 years]; 1584 women [35.9%]) with at least 1 eligible study visit were included in the present analysis. Among non-Hispanic White, non-Hispanic Black, and Hispanic participants, the overall prevalence of therapeutic inertia in the standard vs intensive groups was 59.8% (95% CI, 58.9%-60.7%) vs 56.0% (95% CI, 55.2%-56.7%), 56.8% (95% CI, 54.4%-59.2%) vs 54.5% (95% CI, 52.4%-56.6%), and 59.7% (95% CI, 56.5%-63.0%) vs 51.0% (95% CI, 47.4%-54.5%), respectively. The adjusted odds ratios in the standard and intensive groups for therapeutic inertia associated with non-Hispanic Black vs non-Hispanic White participants were 0.85 (95% CI, 0.79-0.92) and 0.94 (95% CI, 0.88-1.01), respectively. The adjusted odds ratios for therapeutic inertia comparing Hispanic vs non-Hispanic White participants were 1.00 (95% CI, 0.90-1.13) and 0.89 (95% CI, 0.79-1.00) in the standard and intensive groups, respectively. Conclusions and Relevance: Among SPRINT participants above BP target goal, this cross-sectional study found that therapeutic inertia prevalence was similar or lower for non-Hispanic Black and Hispanic participants compared with non-Hispanic White participants. These findings suggest that a standardized approach to BP management, as used in SPRINT, may help ensure equitable care and could reduce the contribution of therapeutic inertia to disparities in hypertension.

Cost-Effectiveness of Intensive versus Standard Blood-Pressure Control.

BACKGROUND: In the Systolic Blood Pressure Intervention Trial (SPRINT), adults at high risk for cardiovascular disease who received intensive systolic blood-pressure control (target, <120 mm Hg) had significantly lower rates of death and cardiovascular disease events than did those who received standard control (target, <140 mm Hg). On the basis of these data, we wanted to determine the lifetime health benefits and health care costs associated with intensive control versus standard control. METHODS: We used a microsimulation model to apply SPRINT treatment effects and health care costs from national sources to a hypothetical cohort of SPRINT-eligible adults. The model projected lifetime costs of treatment and monitoring in patients with hypertension, cardiovascular disease events and subsequent treatment costs, treatment-related risks of serious adverse events and subsequent costs, and quality-adjusted life-years (QALYs) for intensive control versus standard control of systolic blood pressure. RESULTS: We determined that the mean number of QALYs would be 0.27 higher among patients who received intensive control than among those who received standard control and would cost approximately $47,000 more per QALY gained if there were a reduction in adherence and treatment effects after 5 years; the cost would be approximately $28,000 more per QALY gained if the treatment effects persisted for the remaining lifetime of the patient. Most simulation results indicated that intensive treatment would be cost-effective (51 to 79% below the willingness-to-pay threshold of $50,000 per QALY and 76 to 93% below the threshold of $100,000 per QALY), regardless of whether treatment effects were reduced after 5 years or persisted for the remaining lifetime. CONCLUSIONS: In this simulation study, intensive systolic blood-pressure control prevented cardiovascular disease events and prolonged life and did so at levels below common willingness-to-pay thresholds per QALY, regardless of whether benefits were reduced after 5 years or persisted for the patient's remaining lifetime.

Dental Care in an Equal Access System Valuing Equity: Are There Racial Disparities?

BACKGROUND: Racial disparities in dental care have previously been shown in the Veterans Health Administration (VA)-a controlled access setting valuing equitable, high-quality care. OBJECTIVES: The aim of this study is to examine current disparities in dental care by focusing on the receipt of root canal therapy (RCT) versus tooth extraction. RESEARCH DESIGN: This is a retrospective analysis of data contained in the VA's electronic health records. We performed logistic regressions on the independent measures along with a facility-specific random effect, using dependent binary variables that distinguished RCT from tooth extraction procedures. SUBJECTS: VA outpatients who had at least 1 tooth extraction or RCT visit in the VA in fiscal year 2011. MEASURES: A dependent binary measure of tooth extraction or RCT. Other measures are medical record data on medical comorbidities, dental morbidity, prior dental utilization, and demographic characteristics. RESULTS: The overall rate of preferred tooth-preserving RCT was 18.1% during the study period. Black and Asian patients were most dissimilar with respect to dental morbidity, medical and psychological disorders, and black patients had the least amount of eligibility for comprehensive dental care. After adjustment for known confounding factors of RCT, black patients had the lowest RCT rates, whereas Asians had the highest. CONCLUSIONS: Current quality improvement efforts and a value to improve the equity of care are not sufficient to address racial/ethnic disparities in VA dental care; rather more targeted efforts will be needed to achieve equity for all.

A Brief, Multifaceted, Generic Intervention to Improve Blood Pressure Control and Reduce Disparities Had Little Effect.

BACKGROUND: Poor blood pressure (BP) control and racial disparities therein may be a function of clinical inertia and ineffective communication about BP care. METHODS: We compared two different interventions (electronic medical record reminder for BP care (Reminder only, [RO]), and clinician training on BP care-related communication skills plus the reminder (Reminder + Training, [R+T]) with usual care in three primary care clinics, examining BP outcomes among 8,866 patients, and provider-patient communication and medication adherence among a subsample of 793. RESULTS: Clinician counseling improved most at R+T. BP improved overall; R+T had a small but significantly greater reduction in diastolic BP (DBP; -1.7 mm Hg). White patients at RO experienced greater overall improvements in BP control. Site and race disparities trends suggested that disparities decreased at R+T, either stayed the same or decreased at Control; and stayed the same or increased at RO. CONCLUSIONS: More substantial or racial/ethnically tailored interventions are needed.

Explaining racial disparities in anticoagulation control: results from a study of patients at the Veterans Administration.

Higher rates of stroke, major hemorrhage, and death among black patients receiving warfarin, compared with white patients, is likely related to poorer anticoagulation control. The research team investigated patient-level and site-level factors that might account for this group difference. A summary measure of anticoagulation control (percent time in therapeutic range [TTR]), patient characteristics, and site-level process of care measures were obtained for 9572 black and 88 481 white patients at the Veterans Health Administration. The research team studied disparity in TTR adjusting for patient and site characteristics. Mean unadjusted TTR for black patients was 6.5% lower than for white patients (P<.001). After accounting for the younger age of blacks, greater degrees of medication use, hospitalization, poverty, living in the South, and 11 other patient characteristics, only 2.0% of this racial disparity persisted. Process of care measures had minimal additional effect. These findings may inform efforts to reduce this racial disparity in achieving good anticoagulation control.

The quality of quality measures: HEDIS® quality measures for medication management in the elderly and outcomes associated with new exposure.

BACKGROUND: Clinical validation studies of the Healthcare Effectiveness Data and Information Set (HEDIS®) measures of inappropriate prescribing in the elderly are limited. OBJECTIVES: The objective of this study was to examine associations of new exposure to high-risk medication in the elderly (HRME) and drug-disease interaction (Rx-DIS) with mortality, hospital admission, and emergency care. METHODS: A retrospective database study was conducted examining new use of HRME and Rx-DIS in fiscal year 2006 (Oct 2005-Sep 2006; FY06), with index date being the date of first HRME/Rx-DIS exposure, or first day of FY07 if no HRME/Rx-DIS exposure. Outcomes were assessed 1 year after the index date. The participants were veterans who were ≥65 years old in FY06 and received Veterans Health Administration (VA) care in FY05-06. A history of falls/hip fracture, chronic renal failure, and/or dementia per diagnosis codes defined the Rx-DIS subsample. The variables included a number of new unique HRME drug exposures and new unique Rx-DIS drug exposure (0, 1, >1) in FY06, and outcomes (i.e., 1-year mortality, hospital admission, and emergency care) up to 1 year after exposure. Descriptive statistics summarized variables for the overall HRME cohort and the Rx-DIS subset. Multivariable statistical analyses using generalized estimating equations (GEE) models with a logit link accounted for nesting of patients within facilities. For these latter analyses, we controlled for demographic characteristics, chronic disease states, and indicators of disease burden the previous year (e.g., number of prescriptions, emergency/hospital care). RESULTS: Among the 1,807,404 veterans who met inclusion criteria, 5.2 % had new HRME exposure. Of the 256,388 in the Rx-DIS cohort, 3.6 % had new Rx-DIS exposure. Multivariable analyses found that HRME was significantly associated with mortality [1: adjusted odds ratio (AOR) = 1.62, 95 % CI 1.56-1.68; >1: AOR = 1.80, 95 % CI 1.45-2.23], hospital admission (1: AOR = 2.31, 95 % CI 2.22-2.40; >1: AOR = 3.44, 95 % CI 3.06-3.87), and emergency care (1: AOR = 2.59, 95 % CI 2.49-2.70; >1: AOR = 4.18, 95 % CI 3.71-4.71). Rx-DIS exposure was significantly associated with mortality (1: AOR = 1.60, 95 % CI 1.51-1.71; >1: AOR = 2.00, 95 % CI 1.38-2.91), hospital admission for one exposure (1: AOR = 1.12, 95 % CI 1.03-1.27; >1: AOR = 1.18, 95 % CI 0.71-1.95), and emergency care for two or more exposures (1: AOR = 1.06, 95 % CI 0.97-1.15; >1: AOR = 2.0, 95 % CI 1.35-3.10). CONCLUSIONS: Analyses support the link between HRME/Rx-DIS exposure and clinically significant outcomes in older veterans. Now is the time to begin incorporating input from both patients who receive these medications and providers who prescribe to develop approaches to reduce exposure to these agents.

The business case for quality improvement: oral anticoagulation for atrial fibrillation.

BACKGROUND: The potential to save money within a short time frame provides a more compelling "business case" for quality improvement than merely demonstrating cost-effectiveness. Our objective was to demonstrate the potential for cost savings from improved control in patients anticoagulated for atrial fibrillation. METHODS AND RESULTS: Our population consisted of 67 077 Veterans Health Administration patients anticoagulated for atrial fibrillation between October 1, 2006, and September 30, 2008. We simulated the number of adverse events and their associated costs and utilities, both before and after various degrees of improvement in percent time in therapeutic range (TTR). The simulation had a 2-year time horizon, and costs were calculated from the perspective of the payer. In the base-case analysis, improving TTR by 5% prevented 1114 adverse events, including 662 deaths; it gained 863 quality-adjusted life-years and saved $15.9 million compared with the status quo, not accounting for the cost of the quality improvement program. Improving TTR by 10% prevented 2087 events, gained 1606 quality-adjusted life-years, and saved $29.7 million. In sensitivity analyses, costs were most sensitive to the estimated risk of stroke and the expected stroke reduction from improved TTR. Utilities were most sensitive to the estimated risk of death and the expected mortality benefit from improved TTR. CONCLUSIONS: A quality improvement program to improve anticoagulation control probably would be cost-saving for the payer, even if it were only modestly effective in improving control and even without considering the value of improved health. This study demonstrates how to make a business case for a quality improvement initiative.

Can administrative data identify active diagnoses for long-term care resident assessment?

Many veterans receive rehabilitation services in Department of Veterans Affairs (VA) nursing homes. Efficient methods for the identification of active diagnoses could facilitate care planning and outcomes assessment. We set out to determine whether diagnostic data from VA databases can be used to identify active diagnoses for Minimum Data Set (MDS) assessments. We evaluated diagnoses being considered for inclusion in MDS version 3.0 and present in at least 15% of a sample of VA nursing home residents. A research nurse following a standardized protocol identified active diagnoses from the medical records of 120 residents. A clinical nurse also identified active diagnoses in 58 of these patients. Inpatient and outpatient diagnoses from the VA National Patient Care Database were identified for the past year. We calculated kappa, sensitivity, and specificity values, considering the nurses' assessments the gold standard. We found that kappa values comparing research nurses and databases were generally poor, with only 8 of the 19 diagnoses having a value >0.60. Levels of agreement between the clinical nurse and administrative data were generally similar. We conclude that VA administrative data cannot be used to accurately identify active diagnoses for nursing home residents. How best to efficiently collect these important data remains uncertain.

Nursing home assessment of cognitive impairment: development and testing of a brief instrument of mental status.

OBJECTIVES: To test the accuracy of a brief cognitive assessment of nursing home (NH) residents and to determine whether facility nurses can reliably perform this assessment. DESIGN: Cross-sectional, independent cognitive screening tests with NH residents. SETTING: Six Department of Veteran Affairs nursing facilities. PARTICIPANTS: Three hundred seventy-four residents from six regionally distributed Veteran Affairs NHs. MEASUREMENTS: Three cognitive assessment instruments: the Brief Interview of Mental Status (BIMS), created for this study; the Minimum Data Set (MDS) 2.0 Cognitive Performance Scale (CPS), and the Modified Mini-Mental State Examination (3MS) as the criterion standard. The 15-point BIMS tests memory and orientation and includes free and cued recall items. Research assistants administered the 3MS and BIMS to all subjects. Facility nurses administered the same BIMS to a subsample. RESULTS: Three hundred seventy-four of 417 (89.7%) residents approached completed the 3MS and research assistant-administered BIMS (BIMS-R); 212 residents also received a facility nurse-administered BIMS (BIMS-N). The BIMS-R was more highly correlated with the 3MS than was the CPS (Pearson correlation coefficient (r)=0.79 vs 0.62; P<.01 for difference). For the subset who received facility assessments, the BIMS-N was also more highly correlated with the 3MS (Pearson r=0.74 vs 0.65; P<.01 for difference). For any impairment (3MS<78), the area under the receiver operator characteristic curve (AUC) was 0.86 for the BIMS, versus 0.77 for the CPS. For severe impairment (3MS<48) the AUC was 0.94, versus 0.85 for the CPS. CONCLUSION: In this population, a brief cognitive test is a more accurate approach to cognitive assessment than the current observational methods employed using the MDS 2.0.

Sex differences in inappropriate prescribing among elderly veterans.

BACKGROUND: Previous studies have suggested that older women may be more likely than older men to receive potentially inappropriate prescriptions. A better understanding of sex differences in inappropriate prescribing can help inform the development of effective interventions. OBJECTIVE: This study was conducted to assess sex differences in rates of inappropriate prescribing before and after accounting for potentially appropriate indications and to examine sex differences in predictors of inappropriate drug use. METHODS: This was a retrospective cohort study of administrative data from the national Veterans Health Administration (VA). Participants were veterans aged >or=65 years who had >or=1 patient visit at VA outpatient facilities in fiscal year 1999 (FY99) and 2000 (FY00). The main outcome measure was the diagnosis-adjusted prevalence of 33 potentially inappropriate medications as judged by the Beers criteria in FY00: overall, by individual drug, and in 3 categories grouped by potential indication ("always avoid," "rarely appropriate," and "some indications"). RESULTS: The study population included 965,756 patients (946,641 men and 19,115 women). Women were more likely than men to receive inappropriate medications overall and in all 3 categories, even after accounting for diagnoses that may have justified the prescription. Women were more likely to receive 16 of the 33 medications (analgesics, psychotropic drugs, and anticholinergic agents), and men were more likely to receive 3 of the 33. After controlling for sociodemographic characteristics, number of medications, and care characteristics, women remained more likely to receive inappropriate drugs. Receipt of geriatric care was equally protective for men and women, although only a small proportion received this care. Psychiatric comorbidity was associated with inappropriate prescribing for men but not for women. CONCLUSIONS: Analgesic, psychotropic, and anticholinergic medications that should be avoided contributed to higher rates of inappropriate drug use among older women than among older men. Targeted efforts to avoid these medications in older women may help reduce overall rates of inappropriate prescribing. Sex-stratified reporting of quality indicators that assess inappropriate prescribing among community-dwelling elders would help monitor the effectiveness of improvement efforts.

The impact of epilepsy on older veterans.

Despite the fact that old age is the time with the highest incidence of epilepsy, little is known specifically about the impact of epilepsy on the daily lives of the elderly. Previous studies have explored the impact of epilepsy on health status in a general population, but typically have not included enough older individuals to adequately describe this population. The study on which this chapter is based used a general survey instrument to begin exploration of this issue in a population of older veterans with epilepsy. Older patients (> or =65 years of age) were identified who had both International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM), codes indicating epilepsy and prescriptions of antiepileptic drugs in national Veterans Affairs (VA) administrative and pharmacy databases during fiscal year 1999. Using these databases, patients were further identified as newly or previously diagnosed. Diagnostic data were then linked with data from the 1999 Large Health Survey of Veteran Enrollees, using encrypted identifiers, and the impact of epilepsy on patients of different ages was assessed using individual scales and component summaries of the Veterans SF-36. Results showed that older individuals with epilepsy had lower scores on measures of both physical and mental health than did their counterparts with no epilepsy. Further, scores associated with mental health functioning were significantly lower for those with newly diagnosed epilepsy than for those with chronic epilepsy, but differences associated with scores on physical functioning were not significant. Thus, while previous studies suggest that the effects of chronic neurological disorders such as epilepsy are most obvious on measures of mental health, these data suggest that older patients experience difficulties in both physical and mental health.

Blood pressure and survival in the oldest old.

OBJECTIVES: To determine the relationship between blood pressure (BP) and all-cause mortality in subjects aged 80 and older with hypertension. DESIGN: Retrospective cohort study with 5 years of follow-up. SETTING: Ten Veterans AFFAIRS (VA) sites. PARTICIPANTS: Four thousand seventy-one ambulatory patients aged 80 and older with hypertension. MEASUREMENTS: The outcome measure was likelihood of survival during the follow-up period. Vital status was obtained from VA and Social Security files. Variables collected for adjustment in Cox regression models were baseline BP, medications, demographics, diagnoses, and health-related quality of life (HRQoL); HRQoL information was available on 1,289 subjects based on Veterans Health Study Short From-36 (SF-36) questionnaire scores. RESULTS: Subjects with higher BP (up to a systolic BP (SBP) of 139 mmHg and a diastolic BP (DBP) of 89 mmHg) were less likely to die during follow-up than subjects with lower BP. After baseline adjustments, the hazard ratio for a 10-point increase in SBP was 0.82 (95% confidence interval (CI)=0.74-0.91), up to a SBP of 139 mmHg, and for DBP was 0.85 (95% CI=0.78-0.92), up to a DBP of 89 mmHg. There was no significant association between survival and BP levels in subjects with uncontrolled hypertension. CONCLUSION: In a cohort of very old, hypertensive veterans, in subjects with controlled BPs, subjects with lower BP levels had a lower 5-year survival than those with higher BPs. This suggests that clinicians should use caution in their approach to BP lowering in this age group.

Assessing potentially inappropriate prescribing in the elderly Veterans Affairs population using the HEDIS 2006 quality measure.

BACKGROUND: Studies have found that 20% to 25% of older patients receive drugs identified as inappropriate by the 1997 Beers criteria. After the addition of 22 new drugs to the 2003 Beers criteria, the National Committee on Quality Assurance convened an expert consensus panel to identify which drugs from the 2003 Beers criteria should always be avoided in the elderly. The resulting list of drugs to avoid was added to the 2006 Health Plan Employer Data and Information Set (HEDIS) to measure the quality of prescribing for the elderly. OBJECTIVE: To use HEDIS 2006 criteria to determine the rate of potentially inappropriate prescribing in the elderly (PIPE) and to determine if patient risk factors are similar to those found using Beers criteria. METHODS: This cross-sectional database study identified older patients receiving drugs included in the HEDIS 2006 criteria using national data from the Veterans Health Administration. Patients aged 65 years or older on October 1, 1999, with at least 2 outpatient visit days during fiscal year 2000, ending September 30, or outpatient visits in fiscal years 1999 and 2000 were included (N=1,096,361). Multivariable logistic regression analyses stratified by gender identified patient characteristics associated with increased risk of HEDIS 2006 drug exposure. Since oral estrogens were considered appropriate at the time of this study, they were excluded from the list of HEDIS 2006 drugs. RESULTS: Overall, 19.6% of older veterans were exposed to HEDIS 2006 drugs. 23.3% of older veteran women and 19.2% of older veteran men. The most commonly prescribed HEDIS 2006 drugs were antihistamines (received by 9.0% of men and 10.7% of women), opioid analgesics (received by 4.6% of men and 5.8% of women), and skeletal muscle relaxants (received by 4.3% of men and 5.3% of women). Propoxyphene was the most commonly used HEDIS 2006 drug, received by 4.5% of men and 5.7% of women, followed by diphenhydramine, received by 3.5% of men and 4.7% of women, and hydroxyzine, received by 3.2% of both men and women. Patients receiving 10 or more medications of any type were at greatest risk of exposure. Men were 8.2 times more likely to receive at least 1 HEDIS 2006 drug than those taking 1 to 3 drugs of any type (95% confidence interval [CI], 8.0-8.4), while women were 9.6 times more likely (95% CI, 8.2-11.2). CONCLUSIONS: Even though we included a slightly different list of drugs to avoid, results for the HEDIS 2006 measure were similar to those of the 1997 Beers criteria. The HEDIS 2006 drugs are commonly prescribed, and there is a distinct need for direct evidence linking HEDIS 2006 PIPE exposure to adverse patient outcomes. To reduce PIPE, it seems necessary to provide additional evidence for clinicians through the conducting of a well-designed study to assess patient outcomes associated with PIPE exposure as defined by the HEDIS criteria.

Racial/ethnic differences in diabetes care for older veterans: accounting for dual health system use changes conclusions.

BACKGROUND: Veterans Health Administration (VHA) databases are used extensively to study racial/ethnic disparities; however, these databases may not capture all care received by VHA patients. OBJECTIVES: We examined the extent to which accounting for non-VHA care changed conclusions about racial/ethnic disparities for VHA patients with diabetes. METHODS: Using a cross-sectional observational study, we analyzed a national sample of noninstitutionalized Hispanic (n = 5931), black (n = 24,670), and white (n = 149,222) VHA patients with diabetes who were at least 65 years of age for receipt of annual HbA1c testing, low-density lipoprotein (LDL) cholesterol testing, or eye examination from VHA and Medicare administrative files. RESULTS: In VHA alone data, adjusting for patient characteristics, Hispanic and black patients were as likely as white patients to receive HbA1c testing (odds ratio 1.06 [95% confidence interval 0.99-1.13] and 1.04 [1.00-1.07], respectively), and more likely to receive eye examinations (1.31 [1.24-1.38] and 1.33 [1.29-1.37], respectively). Hispanic patients were equally likely (1.01 [0.95-1.07]) and black patients were less likely (0.81 [0.79-0.84]) to receive LDL testing versus white patients. In VHA plus Medicare data, Hispanic and black patients were less likely than white patients to receive HbA1c (0.76 [0.71-0.82] and 0.83 [0.80-0.87], respectively) and LDL testing (0.84 [0.79-0.90] and 0.70 [0.68-0.72], respectively), and equally likely to receive eye examinations (0.91 [0.86-0.96]) and 0.98 [0.95-1.01]), respectively). Accounting for VHA facility had little effect on results. CONCLUSIONS: Restricting to VHA data masks racial/ethnic disparities in care of VHA patients. VHA researchers must be aware and supplement VHA data with other sources whenever possible.

Comprehensive health status assessment of centenarians: results from the 1999 large health survey of veteran enrollees.

BACKGROUND: Information on the health status of centenarians provides a means for understanding the health care needs of this growing population. Therefore, we examined the health status of a national cohort of centenarian veteran enrollees. METHODS: Ninety-three centenarian veteran enrollees returned a complete health history questionnaire, which included questions about sociodemographic information, age-associated conditions, health behaviors, health-related quality of life as measured by the Veterans SF-36, and change in health status. RESULTS: Centenarian veteran enrollees are a group with major impairment across multiple dimensions of health-related quality of life despite having a relatively low prevalence of diseases. They had considerable physical limitations as reflected by their physical health summary scores (26.2 +/- 8.3). However, their mental health was comparatively good (mental health summary score 44.1 +/- 12.5). Compared to younger elderly veterans (ages 85-99), centenarians had a lower prevalence of hypertension, angina or myocardial infarction, diabetes, and chronic low back pain (p <.05). Centenarians had significantly worse physical functioning, role physical, vitality, and social functioning scores than did younger elderly veterans. The two groups did not differ in their general health, bodily pain, role emotional, and mental health scores. Centenarians did not perceive much decline in their physical or mental health during the preceding year. CONCLUSIONS: Centenarian veteran enrollees are a group with a low number of age-associated diseases and good mental health despite substantial physical limitations. These results support future studies of services directed toward improvement of function as opposed to those focused solely on the treatment of diseases.

Purchasing or providing nursing home care: can quality of care data provide guidance.

OBJECTIVES: To examine whether quality of care differed for veterans in Department of Veterans Affairs (VA) nursing homes and those on contract in community nursing homes, and whether the VA was contracting with nursing homes providing better quality of care than other nursing homes. DESIGN: Observational study using administrative databases from 1997 to 1999. SETTING: Ten VA and 650 community nursing homes in New York state. PARTICIPANTS: Four thousand seven hundred sixty-three veteran and 195,438 nonveteran residents of these nursing homes. MEASUREMENTS: Risk-adjusted rates of pressure ulcer development, functional decline, behavioral decline, and mortality. RESULTS: Veterans in VA nursing homes were significantly (P< .05) less likely to develop a pressure ulcer (odds ratio (OR)=0.63) but more likely to experience functional decline (OR=1.6) than veterans in community nursing homes. Residents of community nursing homes with VA contracts were significantly (P< .05) less likely to develop a pressure ulcer (OR=0.91) but more likely to die than residents in noncontract homes. Few nursing homes were consistently among the best or worst performers on all measures; only seven of 650 nursing homes were in the top or bottom decile and 34 in the top or bottom quartile for each measure. CONCLUSION: Large purchasers and providers of nursing home care such as the VA are unlikely to find information on quality of care useful in making decisions on whether they should "make" or "buy" care. Nursing homes performing well on one quality measure may perform poorly on another, and it is difficult to identify nursing homes that are consistently among the best or worst. Other consumers may encounter similar difficulties when using data on nursing home quality.

The health status of elderly veteran enrollees in the Veterans Health Administration.

OBJECTIVES: To examine the health status of elderly veteran enrollees, stratified by age group, and compare with nonveteran populations. DESIGN: Cross-sectional study. SETTING: Outpatient. PARTICIPANTS: A total of 1,406,049 veteran enrollees were surveyed, and 887,775 returned the questionnaire (63.1%). Of these, 663,729 (74%) were aged 65 and older. MEASUREMENTS: Patient demographics, comorbid conditions, and health status, which was assessed using the Veterans 36-item short form (SF-36), a reliable and valid measure of health-related quality of life (HRQoL). RESULTS: Elderly veteran enrollees are a group with poor health status across all scales of the Veterans SF-36. Significant decline in HRQoL was found in patients grouped by increasing age (65-74, 75-84, and > or =85). Of the Veterans SF-36 scales, the role physical and role emotional scales and physical functioning presented the largest decrements by age group. The elderly veteran enrollees had poorer health status than older people enrolled in Medicare managed care, ranging from 0.5 to 1 standard deviations worse. CONCLUSION: Elderly veteran enrollees have substantial disease burden, as reflected by major impairments across multiple dimensions of HRQoL. These findings bear important implications for use of services, suggesting that the Veterans Health Administration will require considerable resources to provide care for its aging population.

No racial differences in mortality found among Veterans Health Administration out-patients.

OBJECTIVE: Health care delivery systems that offer equal access to ambulatory care may hold promise for preventing and correcting racial disparities that exist in our health care system as a whole. We examined whether racial differences in mortality rates exist among patients receiving outpatient care within the Veterans Health Administration. STUDY DESIGN AND SETTING: This study used data from the 1998 National Survey of Ambulatory Care Patients, a prospective monitoring system of patient outcomes. We used an outpatient care system in the Veterans Health Administration. We followed 25,172 Whites and 3,517 African-Americans for 48 months. The main study outcome measures were unadjusted and adjusted mortality rates over a 48-month period. RESULTS: African-Americans had significantly lower unadjusted 48-month mortality rates than Whites (33 vs. 40 deaths per 1,000 person-year, hazard ratio, 0.84; 95% confidence interval [CI], 0.75-0.95). After risk adjustment, the mortality rates became similar for African-Americans and Whites (hazard ratio, 0.99; 95% CI, 0.89-1.09). These findings were consistent across all time points evaluated during the 48-month follow-up. CONCLUSIONS: The lack of racial differences in mortality in patients receiving ambulatory care in the Veterans Health Administration is reassuring, given the emphasis on equal access within this health care system. This warrants further research to determine whether efforts to improve access in other settings have the potential to reduce racial disparities in health care.

Do different case-mix measures affect assessments of provider efficiency? Lessons from the Department of Veterans Affairs.

Although case-mix adjustment is critical for provider profiling, little is known regarding whether different case-mix measures affect assessments of provider efficiency. We examine whether two case-mix measures, Adjusted Clinical Groups (ACGs) and Diagnostic Cost Groups (DCGs), result in different assessments of efficiency across service networks within the Department of Veterans Affairs (VA). Three profiling indicators examine variation in resource use. Although results from the ACGs and DCGs generally agree on which networks have greater or lesser efficiency than average, assessments of individual network efficiency vary depending upon the case-mix measure used. This suggests that caution should be used so that providers are not misclassified based on reported efficiency.
