RESUMEN
OBJECTIVES: We analyzed factors associated with improvement in walking ability among respondents to the nationally representative Health and Retirement Study. METHODS: We analyzed data from 6574 respondents aged 53 years or older who reported difficulty walking several blocks, 1 block, or across the room in 2000 or 2002. We examined associations between improvement (versus no change, deterioration, or death) and baseline health status, chronic conditions, baseline walking difficulty, demographic characteristics, socioeconomic status, and behavioral risk factors. RESULTS: Among the 25% of the study population with baseline walking limitations, 29% experienced improved walking ability, 40% experienced no change in walking ability, and 31% experienced deteriorated walking ability or died. In a multivariate analysis, we found positive associations between walking improvement and more recent onset and more severe walking difficulty, being overweight, and engaging in vigorous physical activity. A history of diabetes, having any difficulty with activities of daily living, and being a current smoker were all negatively associated with improvement in walking ability. After we controlled for baseline health, improvement in walking ability was equally likely among racial and ethnic minorities and those with lower socioeconomic status. CONCLUSIONS: Interventions to reduce smoking and to increase physical activity may help improve walking ability in older Americans.

OBJECTIVE: To evaluate changes in patient-reported communication difficulty after a home-based, computer-delivered intervention designed to improve conversational skills in adults with aphasia. DESIGN: Delayed treatment design with baseline, preintervention, postintervention, and follow-up observations. SETTING: Outpatient rehabilitation. PARTICIPANTS: Twenty subjects with chronic aphasia. INTERVENTIONS: Sessions with the speech-language pathologist to develop personally relevant conversational scripts, followed by 9 weeks of intensive home practice using a computer program loaded on a laptop, and weekly monitoring visits with the speech-language pathologist. MAIN OUTCOME MEASURE: Communication Difficulty (CD) subscale of the Burden of Stroke Scale (BOSS). RESULTS: The intervention resulted in a statistically and clinically significant decrease of 6.79 points (P=.038) in the CD subscale of the BOSS during the intervention, maintained during the follow-up period. CONCLUSIONS: The findings of this study provide positive albeit preliminary and limited support for the use of a home-based, computer-delivered language intervention program for improving patient-reported communication outcomes in adults with chronic aphasia. Additional research will be required to examine the efficacy and effectiveness of this intervention.

Objective. The Department of Veterans Affairs funded assisted living, adult family home, and adult residential care for the first time in the Assisted Living Pilot Program (ALPP). This article compares the use and cost for individuals that entered ALPP and a comparison group. Method. This was a nonrandomized study. The comparison group consisted of VA patients who were eligible but did not enter an ALPP facility. The ALPP (n = 393) and comparison (n = 259) groups were followed for 12 months to assess ALPP facility, case management, and health care costs. Results. ALPP facility and ALPP case management costs were respectively $5,560 and $2,830 per individual. Total health care costs, including ALPP costs, were $11,533 higher for the ALPP group compared to the comparison group after adjusting for baseline differences. Discussion. Although ALPP successfully helped individuals transition to longer term care in these facilities, it was more costly than the comparison group.

Objectives. Assisted living programs demonstrate variation in structure and services. The Department of Veterans Affairs funded this care for the first time in the Assisted Living Pilot Program (ALPP). This article presents resident health outcomes and the relationship between facility characteristics and outcomes. Method. This article presents results on 393 ALPP residents followed for 12 months after admission to 95 facilities. Results. A total of 19.8% residents died, and the average activities of daily living impairment did not change significantly. Half of the residents remained in an ALPP facility, with the average resident spending 315 days in the community during the 12-month follow-up period. This article found a limited number of characteristics of structure and staffing to be significantly associated with outcomes. Discussion. If differences among facility characteristics are not clearly related to differences in outcomes, then choices among type of setting can be based on the match of needs to available services, location, or preferences.

BACKGROUND: Approximately 17.1 million adults report having a major depressive episode in 2004 which represents 8% of the adult population in the U.S. Of these, more than one-third did not seek treatment. In spite of the large and extensive literature on the cost of mental health, we know very little about the differences in out-of-pocket expenditures between adults with depression and adults with other major chronic disease and the sources of those expenditures. AIMS: For persons under age 65, compare total and out-of-pocket expenditures of those with depression to non-depressed individuals who have another major chronic disease. METHODS: This study uses two linked, nationally representative surveys, the 1999 National Health Interview Survey (NHIS) and the 2000 Medical Expenditure Panel Survey (MEPS), to identify the population of interest. Depression was systematically assessed using a short form of the World Health Organization's (WHO) Composite International Diagnostic Interview--Short Form (CIDI-SF). To control for differences from potentially confounding factors, we matched depressed cases to controls using propensity score matching. RESULTS: We estimate that persons with depression have about the same out-of-pocket expenditures while having 11.8% less total medical expenditures (not a statistically significant difference) compared to non-depressed individuals with at least one chronic disease. DISCUSSION: High out-of-pocket expenditures are a concern for individuals with chronic diseases. Our study shows that those with depression have comparable out-of-pocket expenses to those with other chronic diseases, but given their lower income levels, this may result in a more substantial financial burden. IMPLICATION FOR POLICY: High out-of-pocket expenditures are a concern for individuals with depression and other chronic diseases. For both depressed individuals and non-depressed individuals with other chronic diseases, prescription drug expenditures contribute most to out-of-pocket expenses. Given the important role medications play in treatment of depression, high copayment rates are a concern for limiting compliance with appropriate treatment.

OBJECTIVES: Describe the supply of inpatient rehabilitation facilities (IRFs) services in 1996 and examine changes between 1996 and 2004, including the impact of the IRF prospective payment system (PPS) in 2002 on organizational trends. DESIGN: Retrospective pre-post design. SETTING: Freestanding and subprovider (distinct-part units) IRFs. PARTICIPANTS: IRFs (N=1424), including 257 freestanding IRFs and 1167 IRF units reported in the Healthcare Cost Report Information System database, from years 1996 to 2004. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Number of IRF openings, IRF closures, beds, and inpatient days. RESULTS: The number of IRFs grew from 1037 to 1183 between 1996 and 2001 and grew to 1235 between 2001 and 2004. The likelihood of IRF closures trended lower after PPS, and there was a significant increase in the likelihood of openings when PPS was introduced. For-profit, rural, and small IRFs were more likely to open over the entire period. There was a 12.9% increase in the number of total inpatient days, somewhat less than the 15.7% growth in IRF beds over the period. There was no impact of PPS on beds available but a significant decline in total inpatient days after PPS. CONCLUSIONS: Inpatient days rose under the Tax Equity and Fiscal Responsibility Act and declined after 2002. Yet the likelihood of openings and closures did not appear to respond to these changes, perhaps because they were modest compared with changes in local IRF markets. The IRF PPS did little to affect service distribution in less well-served areas, although we did find growth in rural areas. Occupancy rates in 2004 were close to rates at the start of the period (70%). This observation implies that IRFs were implementing strategies to recruit a sufficient number of patients, even though bed numbers were increasing and length of stay was declining. Consequently, policy that limits the potential of IRFs to increase patient admissions, such as the limits on admissions to IRFs of patients with conditions other than those included in the 75% rule, is likely to produce substantial decreases in total inpatient days.

OBJECTIVES: We investigated differences in the development of disability in activities of daily living among non-Hispanic Whites, African Americans, Hispanics interviewed in Spanish, and Hispanics interviewed in English. METHODS: We estimated 6-year risk for disability development among 8161 participants 65 years or older and free of baseline disability. We evaluated mediating factors amenable to clinical and public health intervention on racial/ethnic difference. RESULTS: The risk for developing disability among Hispanics interviewed in English was similar to that among Whites (hazard ratio [HR]=0.99; 95% confidence interval [CI] = 0.6, 1.4) but was substantially higher among African Americans (HR=1.6; 95% CI=1.3, 1.9) and Hispanics interviewed in Spanish (HR=1.8; 95% CI=1.4, 2.1). Adjustment for demographics, health, and socioeconomic status reduced a large portion of those disparities (African American adjusted HR=1.1, Spanish-interviewed Hispanic adjusted HR=1.2). CONCLUSIONS: Higher risks for developing disability among older African Americans, and Hispanics interviewed in Spanish compared with Whites were largely attenuated by health and socioeconomic differences. Language- and culture-specific programs to increase physical activity and promote weight maintenance may reduce rates of disability in activities of daily living and reduce racial/ethnic disparities in disability.

BACKGROUND: Watchful waiting (WW) has been shown to be an acceptable option in men with asymptomatic or minimally symptomatic inguinal hernias when clinical and patient-reported outcomes are considered. Although WW is likely to be less costly initially when compared with tension-free repair (TFR) because of the cost of the operation, it is not clear whether WW remains the least costly option when longer-term costs are considered. STUDY DESIGN: We conducted a cost-effectiveness analysis of a randomized controlled trial at six community and academic centers. We examined costs, quality-adjusted life-years (QALY), and cost-effectiveness at 2 years of followup. Costs were assessed by applying Medicare reimbursement rates to patients' health-care use, which was obtained by contacting patients' health-care providers. Quality of life was assessed using the Short Form-36 version 2 health-related quality-of-life survey. Of the 724 men randomized, 641 were available for the economic analysis: 317 were randomized to TFR and 324 were randomized to watchful waiting. RESULTS: At 2 years, TFR patients had $1,831 higher mean costs than WW patients (95% CI, $409-$3,044), with 0.031 higher QALY (95% CI, 0.001-0.058). The cost per additional QALY for TFR patients was $59,065 (95% CI, $1,358-$322,765). The probability that TFR was cost-effective at the $50,000 per QALY level was 40%. CONCLUSION: At 2 years, WW was a cost-effective treatment option for men with minimal or no hernia symptoms.

BACKGROUND: Despite Medicare, medical services are not equally used by elderly women and men in the United States. Our purpose is to examine gender differences in healthcare utilization among older Americans, the persistence of gender differences across race/ethnicity, and the roles of sociodemographic, health, and economic factors to explain differences. METHODS: Data from the 1998-2000 Health and Retirement Study are used to investigate gender differences in use of hospital, outpatient surgery, home health, and physician services. Analyses are controlled for sociodemographic, health (medical conditions, functional health), and economic (income, wealth, education, health insurance) factors. RESULTS: Women are significantly less likely to use hospital service (odds ratio [OR]=0.83) and outpatient surgery (OR=0.85) but are more likely to use home health care (OR=1.27) and physician services (OR=1.45), controlling for sociodemographics. Differences in health needs and economic resources partially mediate the gender differences in physician and home healthcare utilization but do not explain the gender differences in hospital service and outpatient surgery. Notably, African American, Hispanic, and white women compared with men show significantly less use of hospital services. CONCLUSIONS: Gender differences in medical use vary according to the type of services used and are largely consistent across racial/ethnic groups. As the size of the Medicare population increases, promoting equitable use of healthcare resources by both women and men is an important issue in developing healthcare policy and designing public health strategies.

BACKGROUND: Health care costs are generally highest in the year before death, and much attention has been directed toward reducing costs for end-of-life care. However, it is unknown whether cardiovascular risk profile earlier in life influences health care costs in the last year of life. This study addresses this question. METHODS: Prospective cohort of adults from the Chicago Heart Association Detection Project in Industry included 6582 participants (40% women), aged 33 to 64 years at baseline examination (1967-1973), who died at ages 66 to 99 years. Medicare billing records (1984-2002) were used to obtain cardiovascular disease-related and total charges (adjusted to year 2002 dollars) for inpatient and outpatient services during the last year of life. Participants were classified as having favorable levels of all major cardiovascular risk factors (low risk), that is, serum cholesterol level lower than 200 mg/dL (<5.2 mmol/L), blood pressure 120/80 mm Hg or lower and no antihypertensive medication, body mass index (calculated as weight in kilograms divided by the square of height in meters) lower than 25, no current smoking, no diabetes, and no electrocardiographic abnormalities, or unfavorable levels of any 1 only, any 2 only, any 3 only, or 4 or more of these risk factors. RESULTS: In the last year of life, average Medicare charges were lowest for low-risk persons. For example, cardiovascular disease-related and total charges were lower by 10,367 dollars and 15,318 dollars compared with those with 4 or more unfavorable risk factors; the fewer the unfavorable risk factors, the lower the Medicare charges (P for trends <.001). Analyses by sex showed similar patterns. CONCLUSION: Favorable cardiovascular risk profile earlier in life is associated with lower Medicare charges at the end of life.

OBJECTIVE: To examine associations in nondiabetic individuals of 1-h postload plasma glucose measured in young adulthood and middle age with subsequent Medicare expenditures for cardiovascular disease (CVD), diabetes, cancer, and all health care at age 65 years or older using data from the Chicago Heart Association Detection Project in Industry (CHA). RESEARCH DESIGN AND METHODS: Medicare data (1984-2000) were linked with CHA baseline records (1967-1973) for 8,580 men and 6,723 women ages 33-64 years who were free of coronary heart disease, diabetes, and major electrocardiogram (ECG) abnormalities and who were Medicare eligible (65+ years) for at least 2 years. Participants were classified based on 1-h postload plasma glucose levels <120, 120-199, or > or =200 mg/dl. RESULTS: With adjustment for baseline age, cigarette smoking, serum cholesterol, systolic blood pressure, BMI, ethnicity, education, and minor ECG abnormalities, the average annual and cumulative Medicare, total, and diabetes- and CVD-related charges were significantly higher with higher baseline plasma glucose in women, while only diabetes-related charges were significantly higher in men. For example, in women, multivariate-adjusted CVD-related cumulative charges were, respectively, USD 14,260, 18,909, and 21,183 for the three postload plasma glucose categories (P value for trend = 0.035). CONCLUSIONS: These findings suggest that maintaining low glucose levels early in life has the potential to reduce health care costs in older age.

BACKGROUND: High fruit and vegetable intake is associated with lower risk of hypertension, cardiovascular disease, and cancer. Little is known about the relationship of fruit and vegetable intake to health care expenditures. OBJECTIVE: Examine whether fruit and vegetable intake among middle-aged adults is related to Medicare charges-total, cardiovascular disease, cancer-related-in older age. DESIGN: Participants were grouped into one of three strata according to fruit and vegetable intake, determined from detailed dietary history (1958-1959): less than 14 cups per month, 14 to 42 cups per month, or more than 42 cups per month. Combined intake was classified as low, medium, or high. Medicare claims data (1984-2000) were used to estimate mean annual spending for eligible surviving participants (65 years and older) from the Chicago Western Electric Study: 1,063 men age 40 to 55 and without coronary heart disease, diabetes, and cancer at baseline (1957-1958). Cumulative charges before death (n = 401) were also calculated. RESULTS: Higher fruit and fruit plus vegetable intakes were associated with lower mean annual and cumulative Medicare charges (P values for trend .019 to .862). For example, with adjustment for baseline age, education, total energy intake, and multiple baseline risk factors, annual cardiovascular disease-related charges were 3,128 dollars vs 4,223 dollars for men with high vs low intake of fruit plus vegetables. Corresponding figures were 1,352 dollars vs 1,640 dollars for cancer-related charges and 10,024 dollars vs 12,211 dollars for total charges. Results were generally similar for vegetable intake. CONCLUSION: These findings, albeit mostly not statistically significant, suggest that for men high intake of fruits and fruits plus vegetables earlier in life has potential not only for better health status but also for lower health care costs in older age.

OBJECTIVE: We examine the role of economic access in gender and ethnic/racial disparities in the use of health services among older adults. METHODS: Data from the 1993-1995 study on the Asset of Health Dynamics Among the Oldest Old (AHEAD) were used to investigate differences in the 2-year use of health services by gender and among non-Hispanic White versus minority (Hispanic and African American) ethnic/racial groups. Analyses account for predisposing factors, health needs, and economic access. RESULTS: African American men had fewer physician contacts; minority and non-Hispanic White women used fewer hospital or outpatient surgery services; minority men used less outpatient surgery; and Hispanic women were less likely to use nursing home care, compared with non-Hispanic White men, controlling for predisposing factors and measures of need. Although economic access was related to some medical utilization, it had little effect on gender/ethnic disparities for services covered by Medicare. However, economic access accounted for minority disparities in dental care, which is not covered by Medicare. DISCUSSION: Medicare plays a significant role in providing older women and minorities access to medical services. Significant gender and ethnic/racial disparities in use of medical services covered by Medicare were not accounted for by economic access among older adults with similar levels of health needs. Other cultural and attitudinal factors merit investigation to explain these gender/ethnic disparities.

Risk-adjustment of cesarean birthrates has been hampered by inadequacies in the existing secondary data sources or by the need for extensive chart review. This study presents an efficient risk-adjustment model for cesarean birth, based on easily retrievable ICD-9 codes and clinical risk factors least influenced by physician practice style. Data are presented for mothers undergoing 7322 deliveries from 1997-1998 at a large academic medical center with a cesarean birth rate of 15.9%. Multiple logistic regression was used to predict the likelihood of cesarean delivery controlled for maternal age, 10 risk factors identified through ICD-9 coding, and 3 additional clinical variables (nulliparity, birth weight, and gestational age) derived from a perinatal (birth certificate) database. All risk factors were significant predictors of cesarean birth, producing an area under the receiver-operating characteristic curve of 0.86 and a 60-fold increase in cesarean delivery from highest to lowest deciles of predicted risk. This methodology can be used widely for quality improvement without the need for extensive chart review.

The U.S. hospital industry was reshaped during the 1990s, with many hospitals becoming members of health systems and networks. Our research examines whether safety net hospitals (SNHs) were generally included or excluded from these arrangements, and the factors associated with their involvement. Our analysis draws on the earlier work of Alexander and Morrisey (1988), and not only studies factors affecting SNH participation in multihospital arrangements but also updates their earlier study. We constructed measures for hospital market conditions, management, and mission, and examined network and system affiliation patterns between 1994 and 1998. Our findings suggest that larger and more technically advanced hospitals joined systems in the 1990s, which contrasts with 1980s findings that smaller, financially weak institutions joined systems. Further, SNH participation in networks and systems was more common when hospitals faced less market pressure and where only a limited number of unaffiliated hospitals remained. If networks and systems are key parties in negotiating with private payers, SNHs may be going it alone in these negotiations in highly competitive markets.

BACKGROUND/OBJECTIVE: To evaluate the variability in clinical decisions about pressure ulcer management for persons with spinal cord injury (SCI) and expand understanding of the various factors influencing variability. METHODS: Eighty-one SCI physicians and nurses completed a survey on pressure ulcer management. Patient scenarios were used to assess the effect of patient characteristics on provider decisions regarding inpatient treatment of severe pressure ulcers, surgery vs medical management, and amount of healing before discharge. RESULTS: The availability of social support to facilitate bed rest appears to be a more important factor in deciding whether the patient is managed at home vs in the hospital than is the level of injury. Medical condition does not appear to influence surgical vs medical management of severe pressure ulcers. For patients with poor social support, more healing was required before discharge, regardless of their medical condition. Providers were queried about other issues that influence management, including inpatient resource availability, patient preferences, the availability and quality of local home care, and the availability and use of formal care protocols. Respondents were virtually unanimous in their agreement that patients who are compliant with prevention measures can avoid ulcer development. CONCLUSION: Like many health care providers, those who provide care to people with SCI are struggling to provide quality care to improve their patients' lives in the absence of good evidence to guide their treatment decisions. The results of the present study indicate that in situations in which there is no strong empirical evidence, variation in care provided is extensive.

OBJECTIVE: The quality-adjusted life-year (QALY) is a standard outcome measure used in cost-effectiveness analyses. This study investigates whether attainment of federal physical activity guidelines is associated with higher QALY estimates among adults with or at an increased risk for knee osteoarthritis. METHODS: This is a prospective study of 1794 Osteoarthritis Initiative participants. Physical activity was measured using accelerometers at baseline. Participants were classified as (1) Meeting Guidelines [≥150min of moderate-to-vigorous (MV) activity per week acquired in sessions ≥10min], (2) Insufficiently Active (≥1 MV session[s]/week but below the guideline), or (3) Inactive (zero MV sessions/week). A health-related utility score was derived from participant responses to the 12-item Short-Form Health Survey at baseline and 2 years later. The QALY was calculated as the area under utility curve over 2 years. The relationship of physical activity level to median QALY adjusted for socioeconomic and health factors was estimated using quantile regression. RESULTS: Relative to the Inactive group, median QALYs over 2 years were significantly higher for the Meeting Guidelines (0.112, 95% CI: 0.067-0.157) and Insufficiently Active (0.058, 95% CI: 0.028-0.088) groups, controlling for socioeconomic and health factors. CONCLUSION: We found a significant graded relationship between greater physical activity level and higher QALYs. Using the more conservative estimate of 0.058, if an intervention could move someone out of the Inactive group and costs <$2900 over 2 years, it would be considered cost effective. Our analysis supports interventions to promote physical activity even if recommended levels are not fully attained.

OBJECTIVE: Health-related utility measures overall health status and quality of life and is commonly incorporated into cost-effectiveness analyses. This study investigates whether attainment of federal physical activity guidelines translates into better health-related utility in adults with or at risk for knee osteoarthritis (OA). METHODS: Cross-sectional data from 1,908 adults with or at risk for knee OA participating in the accelerometer ancillary study of the Osteoarthritis Initiative were assessed. Physical activity was measured using 7 days of accelerometer monitoring and was classified as 1) meeting guidelines (≥150 bouted moderate-to-vigorous [MV] minutes per week); 2) insufficiently active (≥1 MV bout[s] per week but below guidelines); or 3) inactive (zero MV bouts per week). A Short Form 6D health-related utility score was derived from patient-reported health status. Relationship of physical activity levels to median health-related utility adjusted for socioeconomic and health factors was tested using quantile regression. RESULTS: Only 13% of participants met physical activity guidelines, and 45% were inactive. Relative to the inactive group, median health-related utility scores were significantly greater for the meeting guidelines group (0.063; 95% confidence interval [95% CI] 0.055, 0.071) and the insufficiently active group (0.059; 95% CI 0.054, 0.064). These differences showed a statistically significant linear trend and strong cross-sectional relationship with physical activity level even after adjusting for socioeconomic and health factors. CONCLUSION: We found a significant positive relationship between physical activity level and health-related utility. Interventions that encourage adults, including persons with knee OA, to increase physical activity even if recommended levels are not attained may improve their quality of life.

OBJECTIVE: This cross-sectional study examined racial/ethnic differences in meeting the 2008 United States Department of Health and Human Services Physical Activity Guidelines aerobic component (≥150 moderate-to-vigorous minutes/week in bouts of ≥10 minutes) among persons with or at risk of radiographic knee osteoarthritis (RKOA). METHODS: We evaluated African American versus white differences in guideline attainment using multiple logistic regression, adjusting for sociodemographic (age, sex, site, income, and education) and health factors (comorbidity, depressive symptoms, overweight/obesity, and knee pain). Our analyses included adults ages 49-84 years who participated in accelerometer monitoring at the Osteoarthritis Initiative 48-month visit (n = 1,142 with RKOA and n = 747 at risk of RKOA). RESULTS: Two percent of African Americans and 13.0% of whites met the guidelines. For adults with and at risk of RKOA, significantly lower rates of guidelines attainment among African Americans compared to whites were partially attenuated by health factor differences, particularly overweight/obesity and knee pain (with RKOA: adjusted odds ratio [OR] 0.24, 95% confidence interval [95% CI] 0.08-0.72; at risk of RKOA: OR 0.28, 95% CI 0.07-1.05). CONCLUSION: Despite known benefits from physical activity, attainment of the physical activity guidelines among persons with and at risk of RKOA was low. African Americans were 72-76% less likely than whites to meet the guidelines. Culturally relevant interventions and environmental strategies in the African American community targeting overweight/obesity and knee pain may reduce future racial/ethnic differences in physical activity and improve health outcomes.
