ABSTRACT
BACKGROUND: It is important to assess the prevalence of hypogonadism and to identify the correlation between hypogonadism and cancer treatment with quality of life (QoL) in germ cell tumor (GCT) survivors. METHODS: This is a single-center, non-randomized, prospective observational study in GCT survivors 18-50 years of age previously treated with surgery and chemotherapy (S+C) or surgery alone (S). Patients completed a validated QoL questionnaire at baseline, 3, and 6 months. Patients received supplemental testosterone as clinically indicated. Mean QoL scores were compared between two treatment groups (S+C vs. S) and within each group between survivors with hypogonadism (serum testosterone level < 300 ng/dL) versus without. A two-sided independent-groups t test was used to compare means. RESULTS: We evaluated 199 GCT survivors. At baseline, the prevalence of biochemical hypogonadism was 48% overall, 51% in S+C group, and 45% in S group (p = .4). Overall, there was no statistically significant difference in QoL scores between S+C and C groups, except the S+C group exhibited greater modified Aging Male Symptoms (AMS) at baseline and 6 months. Patients with hypogonadism reported more fatigue, poor sleep quality, and worse general health at baseline. There were no statistical differences in mean QOL scores between patients with testosterone < 300 ng/dL who received testosterone supplementation and who did not. CONCLUSION: A significant proportion of GCT survivors have low testosterone levels after platinum-based chemotherapy and surgery as well as with just surgery alone. GCT survivors treated with platinum-based chemotherapy exhibited more symptoms related to male aging compared with survivors treated with surgery alone.

BACKGROUND: Emerging adults with diabetes are assuming diabetes care responsibility, graduating from high school and leaving their parental homes. We examined: (1) how diabetes care responsibility changed in relation to time (high school to post high school) and living situation (living independently or not of parents) and (2) the association of diabetes self-efficacy, worry about hypoglycaemia, gender and glycaemic control with these changes in responsibility among emerging adults with type 1 diabetes. METHODS: During the last 6 months in high school (T1), 113 participants completed diabetes care responsibility (total, daily and non-daily), diabetes self-efficacy and worry about hypoglycaemia scales. Participants again completed the responsibility scales post high school graduation (T2). We used a linear mixed-effects model with diabetes self-efficacy, worry about hypoglycaemia, time since graduation, living situation, gender and glycaemic control as independent variables; and diabetes care responsibility (total, daily and non-daily) as dependent variables. Moderation involving diabetes self-efficacy, worry about hypoglycaemia, gender and glycaemic control was also tested. FINDINGS: Diabetes care responsibility increased over time for total (P < 0.001), daily (P= 0.002) and non-daily (P < 0.001), but the associations of self-efficacy and gender with diabetes care responsibility were moderated by living situation. Self-efficacy was negatively related to total (P= 0.006), daily (P= 0.010) and non-daily (P= 0.030) responsibility for those not living independently while positively related only to total responsibility (P= 0.028) for those living independently. Being female was positively related to total (P= 0.007) and non-daily (P= 0.001) responsibility for those living independently. CONCLUSION: Diabetes care responsibility increased from high school to post high school among these emerging adults with diabetes. There is a complex relationship between self-efficacy, gender and responsibility related to living independently of parents for these youth.

PURPOSE: Parent-adolescent shared responsibility for diabetes care is advocated by experts to achieve beneficial diabetes and psychosocial outcomes for adolescents with type 1 diabetes. Parental autonomy support may be a way to facilitate this sharing. In this dyadic study, we examined parental diabetes-specific autonomy support experienced by adolescents with type 1 diabetes and their parents (n = 89 dyads), and its association with their experience of shared diabetes care responsibility. METHODS: Path analysis was used to test an Actor-Partner Interdependence Model for parental autonomy support effects on shared responsibility. This was a secondary analysis of data from 89 parent-early/mid-adolescent dyads. RESULTS: Actor effects were identified. Parents' and adolescents' perceptions of parental autonomy support were associated with their respective reports of shared diabetes care responsibility. One partner effect was identified. Adolescents' reports of parental autonomy support were associated with parents' reports of shared responsibility. Parents and adolescents held similar views of autonomy support but discrepant views of shared responsibility. Older adolescents perceived less parental autonomy support. CONCLUSION: Increasing parental autonomy support may facilitate parent-adolescent sharing of diabetes care responsibility. Adolescent and parent perceptions influence each other and need to be considered when working with them to strengthen parental autonomy support.

This study examined the course of adaptation as indicated by the level of emotional distress for family caregivers of adult BM recipients across the acute phase of the transplant trajectory. Factors influencing caregivers' adaptation that could be potential markers of vulnerability to psychological and social morbidity were identified. The sample included 192 caregivers of either an autologous or allogeneic BMT recipient. Data were collected by self-report questionnaires at three time points in the trajectory: pre-transplant/pre-hospitalization (T1); during hospitalization, post-infusion (T2); 1 month post-discharge (T3). There was a decline in emotional distress from T1 to T3, and bivariate correlations indicated significant association of distress with variables hypothesized to be theoretically relevant. Specifically, greater personal control, a greater sense of spiritual connectedness, less disruption in the life of the caregiver and less use of avoidance coping were the strongest factors associated with lower emotional distress. In conclusion (1) levels of personal control and spirituality remained stable across time and were negatively associated with emotional distress. Therefore, they may provide an indication of caregiver resilience pre-transplant; (2) level of recipient symptomatology rather than BMT type appears to influence caregiver distress; (3) there are indications of the need for post-hospitalization follow-up with caregivers by the BMT team.

OBJECTIVE: Electronic medical records seldom integrate performance indicators into daily operations. Assessing quality indicators traditionally requires resource intensive chart reviews of small samples. We sought to use an electronic medical record to assess use of beta-adrenergic antagonist medications (beta-blockers) following myocardial infarction, to compare a standardized manual assessment with assessment using electronic medical records, and to discuss potential for future integration of performance indicators into electronic records. DESIGN: Cross-sectional data analysis. SETTING: An urban academic medical center. PARTICIPANTS: US Medicare beneficiaries 65 years of age or older, admitted to hospital with myocardial infarction between 1995 and 1999. MEASUREMENTS AND MAIN RESULTS: Manual chart review was compared with a computer driven assessment of electronic records. Administration of beta-blockers and cases excluded from use of beta-blockers were measured, based on Medicare criteria. Among 4490 older adults, 391 (4%) of 9018 hospital admissions contained codes for myocardial infarction. In 323 (83%) of the 391 hospital admissions, criteria for excluding beta-blockers were met; 235 (60%) were excluded due to heart failure. Of 68 hospital admissions for myocardial infarction that did not meet exclusion criteria, physicians prescribed beta-blockers in 49 (72%) on admission and 42 (62%) at discharge. Compared with manual chart review, electronic review had a sensitivity of 83-100% and led to fewer false negative findings. CONCLUSIONS: An electronic medical records system can be used instead of chart review to measure use of beta-blockers after myocardial infarction. This should lead to integration of real time automated performance measurement into electronic medical records.

OBJECTIVES: This study is an investigation of physical activity promotion among a nonvolunteer sample of community-dwelling, older, urban primary care patients. Our primary interest was in the rates of exercise test and class participation. Of secondary interest were the medical record and baseline survey predictors of test and class participation. METHODS: The first 500 nonterminally ill women ages 50 years or more with a visit at one of two predominantly African-American, inner-city primary care clinics received a physician screen, a referral to a submaximal exercise test, and, subsequently, a free, supervised exercise program located in a nearby community center. RESULTS: Eighty-one percent were eligible for the exercise test per provider screen. Of these, 29% completed the exercise test and 28% attended at least one exercise class. After 1 year, 9.2% were attending the exercise classes. Higher exercise outcome expectations, not smoking, and clinic site were associated with exercise test and class participation. CONCLUSIONS: Providing free, traditional exercise classes and a primary care referral to the classes resulted in limited physical activity participation among older, urban primary care patients. More development and testing of physical activity promotion programs are needed in this population.

OBJECTIVE: To assess the impact of cognitive impairment on mortality in older primary care patients after controlling for confounding effects of demographic and comorbid chronic conditions. DESIGN: Prospective cohort study. SETTING: Academic primary care group practice. PARTICIPANTS: Three thousand nine hundred and fifty-seven patients age 60 and older who completed the Short Portable Mental Status Questionnaire (SPMSQ) during routine office visits. MEASUREMENTS: Cognitive impairment measured at baseline using the SPMSQ, demographics, problem drinking, history of smoking, clinical data (including weight, cholesterol level, and serum albumin), and comorbid chronic conditions collected at baseline; survival time measured during the 5 to 7 years after baseline. RESULTS: Eight hundred and eighty-six patients (22.4%) died during the 5 to 7 years of follow-up. Cognitive impairment was categorized as having no impairment (84.3%), mild impairment (10.5%), and moderate-to-severe impairment (5.2%) based on SPMSQ score. Chi-square tests revealed that patients with moderate-to-severe impairment were significantly more likely to die compared with patients with mild impairment (40.8% vs 21.5%) and those with no impairment (40.8% vs 21.4%). No significant difference in crude mortality was found between patients with no impairment and those with mild impairment. After analyzing time to death using the Kaplan-Meier method, patients with moderate-to-severe cognitive impairment were at increased risk of death compared with those with no or mild impairment (Log-rank chi(2) = 55.5; P <.0001). Even in multivariable analyses using Cox proportional hazards to control for confounding factors, compared with those with no impairment, moderately-to-severely impaired patients had an increased risk of death, with a hazard ratio (HR) of 1.70. Increased risk of death was also associated with older age (HR = 1.03 for each year), a history of smoking (HR = 1.48), having a serum albumin level <3.5 g/L (HR = 1.29), and weighing less than 90% of the ideal body weight (HR = 1.98). Outpatient diagnoses associated with increased mortality risk were diabetes mellitus, coronary artery disease, congestive heart failure, cerebrovascular disease, cancer, anemia, and chronic obstructive pulmonary disease (HR range 1.36-1.67). Factors protective of mortality risk included female gender (HR = 0.67) and black race (HR = 0.73). CONCLUSIONS: Moderate-to-severe cognitive impairment is associated with an increased risk of mortality, even after controlling for confounding effects of demographic and clinical characteristics. Mild cognitive impairment is not associated with mortality risk, but a longer follow-up period may be necessary to identify this risk if it exists.

UNLABELLED: To estimate age group differences in the prevalence and outcomes of three common and often comorbid metabolic conditions (i.e., obesity, hypertension, and diabetes) and heart disease. DESIGN: Nationally representative prospective cohort study. SETTING: PARTICIPANTS' homes. PARTICIPANTS: 9825 adults aged 51 to 61 years (middle-age) in 1992, and 7370 adults aged 70 years and over (older-age) in 1993. MEASUREMENTS: Two-year dichotomous outcomes included: doctor visits, hospitalization, mobility difficulty, activity of daily living limitation, poor perceived health, and mortality. Odds ratios (OR) were adjusted for sociodemographic characteristics and history of cancer or lung disease. RESULTS: Those with one condition represented 80% and 70% of the middle- and older-age groups, respectively, while just 1-2% of each age group reported all three metabolic conditions. Thirteen percent and 32%, respectively, reported heart disease with or without metabolic conditions. Diabetes comorbid with other metabolic conditions, and particularly with heart disease, substantially elevated the risk of adverse outcomes such as health-related quality of life deficits, health services use, and mortality in both middle- and older-age adults. In the middle-age group, the OR was 6.81 for mortality in patients with a combination of obesity and diabetes and 6.10 in those with a combination of heart disease and diabetes. There also were significant ORs for mortality in middle-aged patients with heart disease (OR = 2.40), diabetes (OR = 2.63) and for those with a combination of obesity, hypertension, and diabetes (OR = 3.26). CONCLUSION: The impact of these often comorbid conditions underscores the importance of targeted and aggressive prevention, particularly among middle-age adults.

OBJECTIVES: The effectiveness of percutaneous endoscopic gastrostomy (PEG) in older adults remains controversial. Although prior studies have examined the safety of PEG and its impact on nutrition, there are limited data on the economic costs. The purpose of this study is to describe the healthcare costs associated with PEG tube feeding over 1 year. DESIGN: Prospective cohort study. SETTING: Small community of approximately 60,000 residents served by two hospital systems. PARTICIPANTS: One hundred five (70%) of 150 patients age 60 and older receiving PEG over a 24-month period in the targeted community who permitted access to their medical records. MEASUREMENTS: Patients were interviewed at baseline and every 2 months for 1 year to obtain information on use of enteral formula, complication rates, and health services use. We obtained inpatient charge data for all hospitalizations and PEG procedures for 1 year. RESULTS: Censoring patients at death or 1 year post-PEG, the mean number of days of PEG tube feeding was 180 (range 5-365). The average cost for PEG tube feeding for this cohort of patients was $7,488 (median $3,691) in 1997 and 1998. The average daily cost of PEG tube feeding was $87.21 (median $33.50). The estimated cost of providing 1 year of feeding via PEG is $31,832 (median $12,227). The main components of this cost include the initial PEG procedure (29.4%), enteral formula (24.9%), and hospital charges for major complications (33.4%). CONCLUSIONS: Direct charges associated with PEG tube feeding over 1 year are conservatively estimated at $31,832; there was considerable variation in charges because of the cost of rare but costly major complications. Also, feeding patients via PEG resulted in cost shifts in terms of the primary payor. The economic cost of PEG tube feeding is another consideration in decision making for long-term enteral feeding among older adults.

OBJECTIVE: Percutaneous endoscopic gastrostomy (PEG) has become the preferred method to provide enteral tube feeding to older adults who have difficulty eating, but the impact of PEG on patient outcomes is poorly understood. The objective of this study was to describe changes in nutrition, functional status, and health-related quality of life among older adults receiving PEG. DESIGN: A prospective cohort study. SETTING: A small community of approximately 60,000 residents served by two hospital systems. PARTICIPANTS: One hundred fifty patients aged 60 and older receiving PEG from one of the four gastroenterologists practicing in the targeted community. MEASUREMENTS: Patients were assessed at baseline and every 2 months for 1 year to obtain clinical characteristics, process of care data, physical and cognitive function, subjective health status, nutritional status, complications, and mortality. RESULTS: Over a 14-month period, 150 patients received PEG tubes in the targeted community; the mean age was 78.9. The most frequent indications for the PEG were stroke (40.7%), neurodegenerative disorders (34.7%), and cancer (13.3%). All measures of functional status, cognitive status, severity of illness, comorbidity, and quality of life demonstrated profound and life-threatening impairment; 30-day mortality was 22% and 1-year mortality was 50%. Among patients surviving 60 days or more, at least 70% had no significant improvement in functional, nutritional, or subjective health status. Serious complications were rare, but most patients experienced symptomatic problems that they attributed to the enteral tube feeding. CONCLUSIONS: PEG tube feeding in severely and chronically ill older adults can be accomplished safely. However, there are important patient burdens associated with the PEG and there was limited evidence that the procedure improves functional, nutritional, or subjective health status in this cohort of older adults. The issues raised in this descriptive study provide impetus for a randomized trial of PEG tube feeding compared with alternative methods of patient care for older adults with difficulty eating.

OBJECTIVES: The amount of medication dispensed to older adults for the treatment of chronic disease must be balanced carefully. Insufficient medication supplies lead to inadequate treatment of chronic disease, whereas excessive supplies represent wasted resources and the potential for toxicity. We used an electronic medical record system to determine the distribution of medications supplied to older urban adults and to examine the correlations of these distributions with healthcare costs and use. DESIGN: A cross-sectional study using data acquired over 3 years (1994-1996). SETTING: A tax-supported urban public healthcare system consisting of a 300-bed hospital, an emergency department, and a network of community-based ambulatory care centers. PATIENTS: Patients were >60 years of age and had at least one prescription refill and at least two ambulatory visits or one hospitalization during the 3-year period. MEASUREMENTS: Focusing on 12 major categories of drugs used to treat chronic diseases, we determined the amounts and direct costs of these medications dispensed to older adult patients. Amounts of medications that were needed by patients to medicate themselves adequately were compared with the medication supply actually dispensed considering all sources of care (primary, emergency, and inpatient). We calculated the excess drug costs attributable to oversupply of medication (>120% of the amount needed) and the drug cost reduction caused by undersupply of medication (<80% of the amount needed). We also compared total healthcare use and costs for patients who had an oversupply, an undersupply, or an appropriate supply of their medications. RESULTS: The cohort comprised 4164 patients with a mean age of 71 +/- 7 (SD) who received a mean of 3 +/- 2 (SD) drugs for chronic conditions. There were 668 patients (16%) who received <80% of the supply needed, 1556 patients (37%) who received between 80 and 120% of the supply needed, and 1940 patients (47%) who received >120% of the supply needed. The total direct cost of targeted medications for 3 years was $1.96 million or, on average, $654,000 annually. During the 3-year period, patients receiving >120% of their needed medications had excess direct medication costs of $279,084 or $144 per patient, whereas patients receiving <80% of drugs needed had reduced medication costs of $423,438 or $634 per patient. Multivariable analyses revealed that both under- and over-supplies of medication were associated with a greater likelihood of emergency department visits and hospital admissions. CONCLUSIONS: More than one-half of the older adults in our study have under- or over-supplies of medications for the treatment of their chronic diseases. Such inappropriate supplies of medications are associated with healthcare utilization and costs.

BACKGROUND: Understanding older adults' volume and patterns of health service use is fundamental to efforts to improve the quality and efficiency of services. OBJECTIVE: To analyze the accuracy of older adults' self report of health services use and to determine the proportion of care obtained outside a defined urban academic health care system. RESEARCH DESIGN: Telephone survey of self-reports validated against data routinely archived in an electronic medical record system. SUBJECTS: Stratified random sample of 422 patients (> or = 60 years) who had contact with the health care system at least once in the previous 3 months. MEASURES: Self reports of hospitalizations, emergency room visits, physicians visits, extended care visits, and home care visits over the past 12 months, health status, physical activity, and sociodemographics factors. RESULTS: The sample population was more likely to report health services use and functional disability than was a community-based sample of older adults; 67% of the sample were women, 53.9% were African American, 71% were age 65 and over, 38.7% lived alone, and 24.6% reported poor financial resources. Based on data from the electronic medical record, 27.9% of the sample were hospitalized at least once in the prior 12 months, 54.6% had at least one emergency room visit, and the mean number of ambulatory visits was 8.1. Comparing self-report data to the electronic record data, 24.1% of older adults with a hospitalization in the prior 12 months failed to report the episode; 28.1% of those with an emergency room visit failed to report the episode as did 5.2% of those with an ambulatory care visit. The accuracy of the self reports of volume of these services were also substantially under reported. We were unable to identify any patient characteristics that were highly correlated with inaccuracy. We estimate that approximately 9.5% of health care costs are accrued outside this urban health care system. CONCLUSIONS: These older adults substantially under-report health services use, including hospital episodes over a 12-month period. Reliance on self-reported use data over the prior year to model patterns of health care use among older adults is not supported by these data.

BACKGROUND: Urban academic medical centers provide care for large populations of vulnerable older adults. These patients often suffer a disproportionate share of chronic illnesses, disabilities, and social stressors that may increase health care costs. OBJECTIVE: To describe the distribution and content of total healthcare costs accrued over a 4-year period by a community of older adults cared for in an urban academic healthcare system and to describe high-cost patients and utilization patterns. DESIGN: A cohort study. SETTING: A tax-supported public healthcare system consisting of a 450-bed hospital and seven community-based ambulatory care centers. PATIENTS: 12,581 patients aged 60 years and older who had at least two ambulatory visits and/or one hospitalization within the healthcare system from 1993 through 1995. MEASUREMENTS: Patient demographic and clinical characteristics, hospital and ambulatory utilization rates, and all healthcare costs accrued from 1993 through 1996 were determined. Costs were estimated from the perspective of the healthcare system using cost to charge ratios. MAIN RESULTS: The mean patient age was 70 years, 60% were women, 44% were Black, and 83% were covered by Medicare and/or Medicaid. Nearly 25% of patients were obese, 15.8% had a history of smoking, and 15.5% had evidence of malnutrition. The mean number of ambulatory visits per year was 4.3 (+/-7.2), and 38.1% of patients had been hospitalized one or more times. Within the 4-year window, 24.1% of patients had missed five or more appointments with their primary care physicians, 32.7% of patients had five or more unscheduled clinic visits, and 12.5% had five or more emergency room visits. Total health care costs for 4 years for this cohort of older adults was $125.2 million dollars, with per capita annual mean costs of $3893. Expenditures associated with hospitalizations accounted for 63.6% of healthcare costs. Total inpatient and outpatient costs for the 38% of patients hospitalized at least once accounted for 85.3% of all health care expenditures. Patients who died in the hospital did not accrue significantly greater costs than patients who died out of the hospital. Simulations of a random 5% adverse selection of high-cost patients among two capitated systems resulted in cost shifts of $11.1 million. Recorded smoking history, obesity, and low serum albumin were significantly associated with excess costs. CONCLUSIONS: Healthcare costs are concentrated in a significant minority of older adults. Costs accrued in conjunction with hospital stays dominate healthcare expenditures for this cohort of older adults. However, most older adults (83%) have one or fewer hospital episodes in a 4-year period. Although patients who died accrued greater healthcare costs, these costs were not higher when the death occurred in the hospital. Self-care behaviors are an important target for interventions to reduce costs.

OBJECTIVE: To determine whether depressive symptoms measured at baseline are associated with mortality and to describe the course of depressive symptoms and their relation to physical decline in patients over a 6-year period. DESIGN: Prospective cohort study conducted from 1990 through 1996. SETTING: Urban academic primary care group practice. PATIENTS: A cohort of 3,767 patients aged 60 years and older screened for depressive symptoms during routine office visits using the Centers for Epidemiologic Studies Depression Scale (CES-D) participated in the mortality study. A subsample of 300 patients with CES-D scores 16 or above and a subsample of 100 patients with CES-D scores less than 16 participated in the study of the course of depressive symptoms and physical decline. MEASUREMENTS AND MAIN RESULTS: Mortality by December 1995 was measured for all screened patients; reinterviewed patients completed the CES-D and the Sickness Impact Profile (SIP). The mean follow-up period was 45 months (+/- SD 12.2 months); 561 (14.9%) of the patients died by December 1995. In proportional hazards models, age, gender, race, history of smoking, serum albumin value, and an ideal body weight in the lowest 10% were significant correlates of time to death, but the baseline CES-D was not. Patients with depressive symptoms had significantly worse physical and psychosocial functioning scores on the SIP than did patients without depressive symptoms. Using the generalized estimating equation method, the strongest predictor of the current CES-D score was the patient's prior CES-D score. However, worsening physical functioning score on the SIP was also independently correlated with worse CES-D scores p < or = .001). CONCLUSIONS: Symptoms of depression were not associated with mortality in this cohort of older adults. However, patients with depressive symptoms reported greater functional impairment than did those without depressive symptoms. Moreover, decline in physical functioning was independently correlated with a concurrent increase in depressive symptoms.

Relative to information on activities of daily living, information regarding the onset of and recovery from mobility difficulty has been limited. Drawing upon data gathered from 6,376 self-respondents aged 51-61 years at baseline (1992) who were successfully reinterviewed in 1994 as part of the Health and Retirement Survey, the authors were able to build upon and add to knowledge gained from previous studies of the onset of and recovery from mobility difficulty. Hierarchical logistic regression was used to separate the direct and indirect effects of predictors of mobility difficulty onset and recovery at 2-year follow-up. To separate direct and indirect effects, the authors categorized various predictors as being related to sociodemographic factors, economic factors, health behavior, chronic disease, or physical impairment, and the categories were sequentially incorporated into a series of equations. The order in which the predictors were incorporated into the equations followed from a theoretical model of the disability process. In this study of mobility difficulty, the strongest direct predictors of recovery were having little baseline difficulty and the absence of diabetes mellitus, lung disease, and frequent pain. The strongest direct predictors of onset were female sex, less education, low net worth, lack of private health insurance, obesity, and frequent pain. Few indirect predictors for either onset or recovery were identified. Predictors of recovery were few and differed from predictors of onset. Further efforts are needed to identify modifiable predictors among females, persons with few economic resources, and those with frequent pain.

We use data from the 1993-1995 Assets and Health Dynamics of the Oldest-Old survey to estimate predictors of onset of mobility difficulty, onset of basic activity of daily living (ADL) difficulty, and improvement to no mobility difficulty. Onset of mobility difficulty occurred among 20% of those with no difficulty at baseline (n = 2,857) and was most likely among those 85 years of age or over, women, those with a body-mass index of 30 or over, and those who reported lung disease, arthritis, frequent pain, and poor memory. For those with mobility difficulty at baseline (n = 1,871), improvement occurred among 24% and onset of basic ADL difficulty occurred among 25%. Improvement was more likely among those with difficulty in just one mobility item at baseline, and onset of ADL difficulty was most common among those with difficulty in three or more mobility items at baseline.

OBJECTIVES: The purpose of the study was to estimate the 8-year rate of hospitalization for congestive heart failure (CHF), to report the resources consumed, and to evaluate previously reported risk factors in a nationally representative sample of 7,286 older white and black adults. METHODS: Secondary analysis of baseline interview data was linked to Medicare hospitalization and death records for 1984 to 1991. Hospitalization for CHF was defined as having one or more episodes with an International Classification of Diseases (ninth revision, clinical modification) discharge code of 428. Combined and separate analyses of first-listed and second-through fifth-listed CHF discharge diagnoses were conducted. Multivariable proportional hazards models were used to evaluate the risks in pooled analyses of all white and black men and women and in separate stratified analyses of white men and white women. RESULTS: Over the 8-year period, 1,102 or 15.1% of the 7,286 older white and black adults were hospitalized for CHF (7.1% with first-listed and 8.1% with second- through fifth-listed diagnoses). The 1- and 5-year combined postdischarge mortality rates were 34.7% and 69.0%, respectively. In descending order, the major risk factors for being hospitalized for CHF in the combined, pooled analysis were age, being a white man, having lower body functional limitations, and having self-reported medical histories of coronary heart disease, heart attack, diabetes, and angina. The increased risk associated with age was not linear, and it diminished significantly over the course of life. Some significant differences were observed in the risk factors for hospitalization for first-listed versus second- through fifth-listed CHF and in the risk factors for white women versus white men. CONCLUSIONS: Hospitalization for CHF among older adults is a common, costly event with a poor prognosis. The differential risk for white men remains unexplained and warrants further study.

Activities of daily living (ADLs), instrumental ADLs, and disability markers have traditionally been the most common indicators of functional status. The study on Asset and Health Dynamics Among the Oldest Old (AHEAD) is used to replicate a five-dimensional measurement model composed of these observable indicators among the older adult self-respondents. The items available to measure upper body disability were found wanting, but the lower body disability, and the basic, household, and advanced ADL constructs were confirmed. Analyses of the measurement model separately among subgroups of women, men, Hispanics, Mexican Americans, African Americans, and Whites found no meaningful differences. Two structural models linking the lower body disability, and the basic, household, and advanced ADL constructs to perceived health and depression were also replicated among the older adult self-respondents, as well as separately among African Americans and among Whites. These models reaffirmed the dominant role of lower body disability on the everyday activities of older adults, and on their perceived health and depression.

OBJECTIVES: To estimate the independent effect of hospitalization for congestive heart failure (CHF) on subsequent mortality, readmission for CHF, rehospitalization for any reason, and change in functional status. DESIGN: Secondary analysis of the nationally representative Longitudinal Study on Aging, Baseline (1984) interview data are linked to Medicare hospitalization and death records for 1984-1991 and to functional status reports at three biennial follow-ups. SETTING: In-home and telephone interviews. PARTICIPANTS: a total of 7527 noninstitutionalized older adults aged 70 years or older at baseline. MEASUREMENTS: Hospitalization for CHF was defined as having one or more episodes with primary or secondary discharge ICD9-CM codes of 428. Multivariable proportional hazards, logistic and linear regression, as well as multiple classification analysis, were used to estimate the independent effects of having been hospitalized for CHF. RESULTS: The adjusted risk ratios for having a primary or secondary hospital discharge diagnosis of CHF on mortality (compared with not having any CHF hospital discharge diagnoses) were 1.58 (CI95% = 1.40 to 1.78) and 1.29 (CI95% = 1.15 to 1.45), respectively (P < .001). CHF readmission and rehospitalization rates were substantial, ranging from 16.0 to 47.5% at 1 year, depending on the criteria employed. The adjusted odds ratios for having any subsequent hospitalizations associated with having a primary or secondary hospital discharge diagnosis of CHF (compared with not having any CHF hospital discharge diagnoses) were 7.70 (CI95% = 6.20 to 9.57) and 2.99 (CI95% = 2.51 to 3.56), respectively (P < .001). The percent increases in the number of hospital episodes, total charges, and total length of stay attributable to having been hospitalized for CHF were significant (P < .001) and ranged from 15.5 to 66.7%. Having been hospitalized for CHF was also related significantly to greater increases in the mean number of functional limitations at follow-up. CONCLUSION: Hospitalization for CHF among older adults increases substantially the risk of subsequent mortality, readmission for CHF, rehospitalization for any reason, and greater functional decline. Therefore, greater attention to the prevention and management of CHF is needed.

BACKGROUND: The purpose of the study was to estimate the prevalence of sociodemographic, health behavior, chronic disease, and impairment factors and their impact on difficulty in lower body function among two age-cohorts (51-61 and 71-81 years) of Mexican Americans, African Americans, and Whites. METHODS: Reports from 8,727 and 4,510 self-respondents of the 1992 baseline Health and Retirement Survey and the 1993 baseline Assets and Health Dynamics Study, respectively, were used to estimate prevalence. Multiple linear regression of the 4-item lower body difficulty scale (alpha = .80) was used to estimate the direct effects of the risk factors within the age-cohort and ethnicity groups. RESULTS: Overall, the risk factors are more prevalent among both minority groups and the older age-cohort. Lower body deficits are particularly high among Mexican Americans and the younger age-cohort of African Americans. The impact of risk factors does not vary much by ethnicity or age-cohort. Female gender, pain, arthritis, and heart and lung disease are the major risk factors, and they account for about one-third of the variance in lower body difficulty for each group. CONCLUSIONS: Efforts to prevent or reduce lower body difficulty should pay particular attention to pain, arthritis, and heart and lung disease. The central role of sociodemographic and behavioral factors in chronic disease argues for their continued inclusion in disability modeling and prevention.
