Alcohol use and functional disability among cognitively impaired adults.

BACKGROUND: The extent to which alcohol exposure increases risk for functional disability among older adults with cognitive impairment has not previously been assessed. OBJECTIVE: To examine the potential relationship between alcohol use and functional disability among older cognitively impaired adults. DESIGN: Retrospective medical record review. SETTING: Hospital-based geriatric assessment center. PARTICIPANTS: Two hundred forty-two consecutive participants with Mini-Mental Status Examination scores of < or = 24. MEASUREMENTS: Proxy-reported alcohol intake was classified in categories of never, former, light (< 1 drink/week), moderate (> or = 1 but < 14 drinks/week), and heavy (> or = 14 drinks/week) drinkers, and functional status was determined by proxy-reported performance in seven basic (BADL) and seven instrumental (IADL) activities of daily living (0 = poorest function and 14 = best function). RESULTS: Compared with never drinkers, moderate drinkers demonstrated higher mean BADL (12.2 vs 11.4, P = .033) and IADL scores (6.6 vs 5.6, P = .067), whereas heavy drinkers had higher BADL (12.8 vs 11.4, P = .019) but lower IADL scores (4.8 vs 5.6, P = .425). Former drinkers demonstrated both lower BADL (10.8 vs 11.4, P = .107) and IADL scores (3.9 vs 5.6, P = .011) compared with never drinkers. Evaluation of a potential dose-response effect was limited due to low numbers of light and heavy drinkers. CONCLUSIONS: Among cognitively impaired adults, moderate and heavy drinkers demonstrated better BADL function, whereas former drinkers had poorer IADL function, compared with never drinkers. Prospective studies that incorporate additional measures of exposure (e.g., cumulative lifetime consumption) and function (e.g., performance-based tests) may provide a more comprehensive understanding of alcohol's effects among older cognitively impaired adults.

A population-based study of environmental hazards in the homes of older persons.

OBJECTIVES: This study sought to estimate the population-based prevalence of environmental hazards in the homes of older persons and to determine whether the prevalence of these hazards differs by housing type or by level of disability in terms of activities of daily living (ADLs). METHODS: An environmental assessment was completed in the homes of 1000 persons 72 years and older. Weighted prevalence rates were calculated for each of the potential hazards and subsequently compared among subgroups of participants characterized by housing type and level of ADL disability. RESULTS: Overall, the prevalence of most environmental hazards was high. Two or more hazards were found in 59% of bathrooms and in 23% to 42% of the other rooms. Nearly all homes had at least 2 potential hazards. Although age-restricted housing was less hazardous than community housing, older persons who were disabled were no less likely to be exposed to environmental hazards than older persons who were nondisabled. CONCLUSIONS: Environmental hazards are common in the homes of community-living older persons.

Difficulty and dependence: two components of the disability continuum among community-living older persons.

BACKGROUND: Although most epidemiologic studies have defined disability in basic activities of daily living (BADLs) as dependence, some investigators have argued that BADL disability should be defined as degree of difficulty. OBJECTIVE: To determine whether the responses to questions about difficulty and dependence provide complementary information that together can depict the continuum of disability more fully than the response to either question alone. SETTING: General community. PARTICIPANTS: 1065 persons 72 years of age and older. MEASUREMENTS: On the basis of self-reported information collected at baseline, participants were categorized into three BADL groups: independent without difficulty, independent with difficulty, and dependent. Additional baseline information was collected on several measures of higher-level function and physical performance. Follow-up information was collected on regular home care visits and BADL function at 1 and 3 years and on hospitalizations, admissions to skilled-nursing facilities, and deaths over a 4-year period. RESULTS: In a cross-sectional analysis, the proportion of participants with poor higher-level function and physical performance increased substantially across the three BADL groups. In a longitudinal analysis, the rates of hospitalization and regular home care visits for the independent without difficulty group, the independent with difficulty group, and the dependent group were 46%, 57%, and 72% (P < 0.001) and 17%, 30%, and 49% (P < 0.001), respectively; survival curves for admission to a skilled-nursing facility and death differed significantly for each pair-wise comparison. Among persons who were BADL independent, those with difficulty were significantly more likely to develop BADL dependence over a 3-year period than those without difficulty (31% compared with 18%; P < 0.001). CONCLUSIONS: In the assessment of BADL function in older persons, questions about difficulty and dependence provide complementary information that together can depict the continuum of disability more fully than either question alone.

Older persons' preferences for site of treatment in acute illness.

OBJECTIVE: To explore how older persons form preferences for site of medical care by examining their perceptions of home care and hospital care. DESIGN: Qualitative analysis of in-depth interviews using the constant comparative method. SETTING: Respondents' homes. PARTICIPANTS: Twenty-nine persons age 65 to 89 years who had been hospitalized with congestive heart failure, chronic obstructive pulmonary disease, or pneumonia and were receiving home care services. MAIN RESULTS: Respondents, who thought of home care only as a means to provide low-intensity and low-frequency services, were initially skeptical about expanded home care services to treat acute illness. Regardless of their opinions about home and hospital, all respondents preferred the site associated with the greatest chance of survival. If the sites offered equal survival, 52% of the respondents preferred treatment at home because of freedom from the constraints of the hospital and the comfort of familiar surroundings. For respondents who preferred the hospital, the home represented a frightening and lonely place to be sick. Respondents' views of the home and hospital were shaped by their social supports, self-reliance, religious beliefs, and past illness experiences. CONCLUSIONS: Because survival appears to be the most important determinant of preference, home treatment of acute illness is a viable alternative only if it provides outcomes equivalent to those of hospitalization. Strongly held perceptions that home care can only be a low-intensity service may limit preferences for home treatment. When expected outcomes at the two sites are similar, the challenge to the health care system will be incorporating patient preference about the process of care into decisions about the appropriate site of care.

A taxonomy for goal setting in the care of persons with dementia.

OBJECTIVE: Develop a taxonomy for understanding and classifying goals in the care of persons with dementia. DESIGN: Qualitative study using open-ended interviews with key informants and the constant comparative method of qualitative data analysis. SETTING: The geriatric assessment center at a large academic medical center in Connecticut. PARTICIPANTS: Key informant interviews with 36 subjects: consecutive patients receiving geriatric assessment at the center and their primary family caregivers, case managers, and physicians of patients. MEASUREMENTS AND MAIN RESULTS: Goals, or desired outcomes, for the patient's care as described by patients, primary family caregivers, case managers, and physicians were the main measurements. Participant interviews were conducted until the point of theoretical saturation, i.e., until further interviews no longer provided new concepts. All participants articulated at least one goal. Specific goals were characterized by a limited number of goal attributes resulting in a taxonomy, or consistent classification system, for reported goals. These attributes include domain (or content), specificity, time frame, and level of challenge. CONCLUSIONS: The findings suggested that patients, primary family caregivers, and clinicians can articulate goals of care and may bring differing perspectives to the goal-setting process. The research identified a taxonomy that may facilitate negotiation of goals by revealing important, and perhaps overlooked, aspects of goals and the goal-setting process.

Physician awareness of alcohol use disorders among older patients.

OBJECTIVES: To determine primary care physicians' awareness of, and screening practices for, alcohol use disorders (AUDs) among older patients. DESIGN: Cross-sectional telephone survey of a national sample of primary care physicians. PARTICIPANTS: Physicians randomly sampled from the Masterfile database of the American Medical Association and stratified by specialty as family practice physicians, internal medicine physicians, and either family practice or internal medicine physicians with geriatric certification. MAIN RESULTS: A total of 171 physicians were contacted: 155 (91%) agreed to participate, and responses were analyzed from 150 (50 family practice, 50 internal medicine, 50 with geriatric certification). The median prevalence estimate of AUDs among older patients was 5% for each group of physicians. In contrast to published prevalence rates of AUDs ranging from 5% to 23%, 38% of physicians reported prevalence estimates of less than 5%, and 5% cited estimates of at least 25%. Compared with the other groups, the physicians with geriatric certification were more likely to report no regular screening (42% vs 20% for family practice vs 18% for internal medicine, p = .01), while younger (<40 years) and middle-aged physicians (40-55 years) reported higher annual screening rates relative to older physicians (>55 years) (77% vs 60% vs 44% respectively, p = .03). Among physicians who regularly screened (n = 110), 100% asked quantity-frequency questions, 39% also used the CAGE questions, and 15% also cited use of biochemical markers. CONCLUSIONS: Primary care physicians may "underdetect" AUDs among older patients. The development of age-specific screening methods and physician education may facilitate detection of older patients with (or at risk for) these disorders.

The effect of falls and fall injuries on functioning in community-dwelling older persons.

BACKGROUND: Several preventive strategies have proven effective at reducing the occurrence and rate of falling. It remains to be determined, however, whether, and to what extent, falls and/or fall injuries are independent determinants of adverse functional outcomes in older persons. METHODS: A probability sample of 1,103 community-dwelling persons over age 71 years was followed for 3 years. The 957 cohort members (87%) who participated in at least one follow-up interview while residing in the community were included in this study. Outcome measures included one and three year change in basic and instrumental activities of daily living (BADLs-IADLs), social activities, and physical activities. Based on daily calendars and hospital surveillance, participants were placed into one of four levels of fall status: no falls, one fall without serious injury, at least two falls without serious injury, and one or more falls with serious injury. Hierarchical linear regression models, sequentially adding six domains of covariates, were constructed to examine fall status as a risk factor for change in function. RESULTS: One noninjurious fall (beta = -.437; p < .01), at least two noninjurious falls (beta = -.877; p < .001); and at least one injurious fall (beta = -1.254; p < .001) were each associated with decline in BADL-IADL function over 3 years after adjusting for covariates (model R2 = .2617). Experiencing two or more noninjurious falls (beta = -.538; p < .05) was associated with decline in social activities (model R2 = .2779) while experiencing at least one injurious fall (beta = -.580; p < .01) was associated with decline in physical activity (model R2 = .4231). CONCLUSIONS: Falls and fall injuries appear to be independent determinants of functional decline in community-dwelling older persons. Falling is a health condition meeting all criteria for prevention: high frequency, evidence of preventability, and high burden of morbidity.

Health care utilization and costs in a Medicare population by fall status.

OBJECTIVES: The economic impact of trauma in older persons is a matter of increasing concern to public health practitioners and planners, yet it is an issue that has not been widely studied. Available evidence does suggest, however, that falls are the costliest category of injury among older persons. METHODS: This study used data from the Health Care Financing Administration and the Connecticut Long-Term Care Registry to isolate the effects of fall severity on hospital, nursing home, home health, and emergency room costs. Multivariate and logistic regression methods were used to control for the influence of a number of clinical and demographic factors believed to be independently related to health care costs. Health care costs of fallers were tracked for 1 year after the fall. The cost experience of this cohort was compared with nonfallers during the same time period. RESULTS: The results provide strong evidence that falls are associated with increased health care costs, and that this relation increases monotonically with the frequency and severity of falls. Incurring one or more injurious falls was associated with increased annual hospital costs of $11,042 (1996), nursing home costs of $5,325, and total health care costs of $19,440. Incurring two or more noninjurious falls increased costs substantially as well. CONCLUSIONS: The health care costs of falls are pervasive and substantial, and they increase with fall frequency and severity.

Development of a test battery to identify older drivers at risk for self-reported adverse driving events.

OBJECTIVES: The purposes of this study were (1) to develop a battery of tests that assessed a wide range of functional abilities relevant to driving yet could be performed in a clinician's office and (2) to determine which of these tests were most closely associated with self-reported adverse driving events. DESIGN: A cohort study. SETTING: An urban community. PARTICIPANTS: Participants were drawn from the Project Safety cohort, a probability sample of noninstitutionalized older persons in New Haven, Connecticut, initiated in 1989. The current study included surviving, active drivers in the cohort (N=125). MEASURES: The test battery assessed visual, cognitive, and physical abilities potentially relevant to driving, and was administered in participants' homes by trained interviewers between October 1994 and July 1995. Outcome measures included the self-report of a crash, moving violation, or being stopped by police in any Project Safety interview since the inception of the cohort. Analyses compared performance on the elements of the test battery with participants' histories of adverse driving events. RESULTS: Of the 125 drivers, 50 (40%) had reported an adverse event in a mean period of 5.76 (+/-.25) years before the current interview. The elements of the test battery independently associated with a history of events, adjusting for driving frequency, included near visual acuity worse than 20/40 (adjusted odds ratio 11.90), limited neck rotation (OR 6.10), and poor performance on a test of visual attention, the number cancellation task (OR 3.00). The resulting regression equation yielded a sensitivity of 80%, a specificity of 55%, and an area under the curve of .75 by receiver operating characteristic analysis. CONCLUSION: These findings suggest it may be possible to identify individuals potentially at risk for self-reported adverse driving events using simple tests of functional ability. If validated, such an approach could be used to identify individuals who need a more detailed assessment of functional abilities to determine the severity and etiology of impairments, and their effect on driving performance, as well as possible interventions to correct or compensate for the impairments.

Factors associated with six-month mortality in recipients of community-based long-term care.

OBJECTIVES: To determine factors associated with short-term mortality in recipients of community-based long-term care (CBLTC). DESIGN: A cohort study. SETTING: A Medicaid home- and community-based waiver and state-funded homecare program. PARTICIPANTS: All persons age 65 and older newly admitted to the program from January 1, 1988, to March 31, 1991. MEASUREMENTS: Demographics, functional, cognitive, and health status, depression, and social support were obtained in an admission assessment. Six-month mortality data were obtained by linking assessment data to a state mortality registry. RESULTS: There were 718 deaths among 6784 CBLTC clients. Male sex (AOR 1.8, 95% CI 1.5-2.1), the presence of cancer (AOR 3.2, CI 2.6-3.9), heart disease (AOR 1.3, CI 1.1-1.5), chronic obstructive pulmonary disease (AOR 1.8, CI 1.4-2.2), or nutritional problems (AOR 1.7, CI 1.4-2.0), functional impairment (AOR for lowest compared to highest quartile 2.9, CI 2.0-4.1), severe cognitive impairment (AOR 1.6, CI 1.3-2.1), self-assessment of health as poor (AOR 1.5, CI 1.1-2.0), feeling depressed (AOR 1.2, CI 1.1-1.3), and hospitalization (AOR 2.7, CI 2.2-3.2) were independently associated with 6-month mortality in bivariate and multivariate analyses. CONCLUSIONS: Clinical data obtained during routine assessment of CBLTC clients can be used to assess short-term mortality. Six-month mortality is associated with poor functional and cognitive status, the presence of cancer, heart disease, COPD, and nutritional problems, depression, perception of poor health, and hospitalization.

When the patient cannot come to the doctor: a medical housecalls program.

OBJECTIVES: To describe a medical housecalls program and to assess its ability to meet the medical needs of homebound patients. PROGRAM STRUCTURE: The housecalls program is part of a larger ambulatory practice situated in a senior center staffed by geriatricians and nurse practitioners. The practice serves as the major teaching site of outpatient geriatrics for a medical residency program. Scheduled visits are made every 3 to 4 months, and unscheduled visits are made weekday days for acute problems. PARTICIPANTS: Patients are eligible for the housecalls program if they live within a 15- minute drive of the center and are unable to leave their home. PROGRAM EVALUATION: The majority of the 71 patients in the housecalls program between 1993 and 1995 were female (81%), aged 85 years or older (52%), and dependent in one or more activities of daily living: 65% were dependent in bathing and 42% in dressing. A substantial minority (16%) had severe cognitive impairment. Patients received a mean of 5.0 visits per patient-year. The majority of patients (59%) were treated at home for an acute illness or symptom ranging from upper respiratory tract infections to pneumonia and congestive heart failure. Approximately one-quarter of the patients or their proxies elected to avoid hospitalization; several of these patients had complex illnesses managed in their homes. CONCLUSIONS: A wide range of medical problems can be addressed in patients' homes. Because our patients could not leave their homes easily, or at all, it is probable they would not have received routine medical care and would have used the emergency room for evaluation of acute problems if the housecalls program were not available. Despite their potential value in the care of frail older patients, housecalls will likely not become a widespread practice until barriers to their performance cited by physicians are addressed.

Falls, injuries due to falls, and the risk of admission to a nursing home.

BACKGROUND: Falls warrant investigation as a risk factor for nursing home admission because falls are common and are associated with functional disability and because they may be preventable. METHODS: We conducted a prospective study of a probability sample of 1103 people over 71 years of age who were living in the community. Data on demographic and medical characteristics, use of health care, and cognitive, functional, psychological, and social functioning were obtained at base line and one year later during assessments in the participants' homes. The primary outcome studied was the number of days from the initial assessment to a first long-term admission to a skilled-nursing facility during three years of follow-up. Patients were assigned to four categories during follow-up: those who had no falls, those who had one fall without serious injury, those who had two or more falls without serious injury, and those who had at least one fall causing serious injury. RESULTS: A total of 133 participants (12.1 percent) had long-term admissions to nursing homes. In an unadjusted model, the risk of admission increased progressively, as compared with that for the patients with no falls, for those with a single noninjurious fall (relative risk, 4.9; 95 percent confidence interval, 3.2 to 7.5), those with multiple noninjurious falls (relative risk, 8.5; 95 percent confidence interval, 3.4 to 21.2), and those with at least one fall causing serious injury (relative risk, 19.9; 95 percent confidence interval, 12.2 to 32.6). Adjustment for other risk factors lowered these ratios to 3.1 (95 percent confidence interval, 1.9 to 4.9) for one noninjurious fall, 5.5 (95 percent confidence interval, 2.1 to 14.2) for two or more noninjurious falls, and 10.2 (95 percent confidence interval, 5.8 to 17.9) for at least one fall causing serious injury, but the association between falls and admission to a nursing home remained strong and significant. The population attributable risk of long-term admission to a nursing home for these three groups (the proportion of admissions directly attributable to the three categories of falls) was 13 percent, 3 percent, and 10 percent, respectively. CONCLUSIONS: Among older people living in the community falls are a strong predictor of placement in a skilled-nursing facility; interventions that prevent falls and their sequelae may therefore delay or reduce the frequency of nursing home admissions.

Systematic home-based physical and functional therapy for older persons after hip fracture.

OBJECTIVE: To describe the development, implementation, and results of a home-based rehabilitation protocol for older persons after hip fracture. DESIGN: Demonstration study. SETTING: Community. PARTICIPANTS: One hundred forty-eight community-living, nondemented participants at least 65 years of age who underwent repair of a fractured hip at two local hospitals. INTERVENTION: A linked assessment-intervention, home-based rehabilitation strategy. The physical therapy (PT) component of the intervention was designed to identify and ameliorate impairments in balance, strength, transfers, gait, and stair climbing; the functional therapy (FT) component was designed to identify and improve unsafe and/or inefficient performance of specific activities of daily living (ADL). MAIN OUTCOME MEASURES: The percentage of participants able to complete each component and the extent of progress noted in strength, balance, transfers, gait, and daily functioning. RESULTS: A total of 104 of the 148 participants (70%) completed the 6-month PT and FT program; 4 completed only PT and 6 refused both PT and FT. The remaining 32 participants (22%) received partial PT and FT that was terminated by death, hospitalization, or institutionalization. Seventy-seven percent of participants reported performing at least half of the recommended daily exercise sessions. Ninety-four percent and 96% of participants progressed in upper and lower extremity conditioning respectively; 33% progressed to the highest level in the graduated resisted exercise program. All participants progressed in the competency-based graded balance program, with 55% progressing to the fifth (most difficult) level. Similarly, the majority progressed in transfer maneuvers, stair climbing, and outdoor gait. One repetition maximum (RM) elbow extension increased from a mean of 5.8 (SD 4.6) pounds at baseline to 7.2 (SD 3.8) pounds at 6mo (t 2.22; p < .02). One RM knee extension increased from 5.8 (SD 5.8) pounds to 10.8 (SD 5.4) pounds (t = 8.06; p < .0001). The number of gait deviations decreased from 2.1 (SD 1.3) to 0.6 (SD 0.9) (p < .0001), while the mean modified Berg Balance Scale Score increased from 13.0 (SD 4.8) to 20.5 (SD 6.8) (t = 16.6; p < .0001). Finally, the Total ADL Score increased from a mean of 48.2 (SD 15.0) to 77.7 (SD 18.8) (t = 17.03; p = .0001). CONCLUSIONS: This systematic assessment and intervention protocol, targeting impairments and ADL, was feasible, safe, and effective. Protocols such as the one presented should enhance the ability to implement rehabilitation programs for the increasing number of multiply impaired older persons receiving home-based therapy and to document the process and outcomes of this care.

ED use by older victims of family violence.

STUDY OBJECTIVE: To determine the nature and frequency of ED use by victims of physical elder abuse. METHODS: Community-dwelling victims of abuse were identified through a state elderly protective service program independent of the health care system in a geographic area served by two EDs. ED records were reviewed and abstracted to determine if and how victims used emergency services. RESULTS: During a 7-year period, 182 elderly victims of physical abuse were identified in the catchment area of the study, and 114 (62.6%) had been seen in one or both EDs at least once during a 5-year "window" surrounding the initial identification of abuse. These 114 individuals accounted for 628 visits (median 3, range 1-46); 30.6% of visits resulted in a hospital admission. An ordinal system was used that assigned a probability of any single ED visit being referable to abuse; 37.8% of subjects had at least one visit categorized as being of high probability, and 66% of subjects had at least one visit that resulted in an injury-related chief symptom or ICD-9 discharge diagnosis. CONCLUSION: Elder abuse victims have substantial interactions with EDs and these visits frequently result in admission. Strategies that identify elder abuse in less acute settings and effectively address the needs of victims would improve quality of life and likely result in substantial savings in health care expenditures.

The role of change in physical performance in determining risk for dependence in activities of daily living among nondisabled community-living elderly persons.

Among community-living elderly persons, a single assessment of physical performance is a powerful predictor of dependence in activities of daily living (ADLs). The aim of this study was to determine whether an assessment of change in physical performance provides useful prognostic information beyond that available from a single assessment. Among a large representative cohort of elderly persons, we evaluated the 586 participants who were ADL independent at both the baseline and the one year interviews. For each of the three timed tests, participants who had a large decline in physical performance were significantly more likely to develop ADL dependence at three years than those who improved or showed no change. After adjusting for 1-year scores, however, change in physical performance was no longer associated with ADL dependence. However, among the 775 participants who were ADL independent at the baseline interview, change in physical performance was significantly associated with the onset of ADL dependence at one year, even after adjusting for baseline performance. When determining risk for ADL dependence, an assessment of change in physical performance over one year does not provide useful prognostic information beyond that available from a single assessment. Nevertheless, change in physical performance is independently associated with concurrent ADL dependence and may be useful in predicting future disability if measured over shorter intervals.

Predictors of recovery in activities of daily living among disabled older persons living in the community.

OBJECTIVE: To identify the factors that predict recovery in activities of daily living (ADLs) among disabled older persons living in the community. DESIGN: Prospective cohort study with 2-year follow-up. SETTING: General community. PARTICIPANTS: 213 men and women 72 years or older, who reported dependence in one or more ADLs. MEASUREMENTS AND MAIN RESULTS: All participants underwent a comprehensive home assessment and were followed for recovery of ADL function, defined as requiring no personal assistance in any of the ADLs within 2 years. Fifty-nine participants (28%) recovered independent ADL function. Compared with those older than 85 years, participants aged 85 years or younger were more than 8 times as likely to recover their ADL function (relative risk [RR] 8.4; 95% confidence interval [CI] 2.7, 26). Several factors besides age were associated with ADL recovery in bivariate analysis, including disability in only one ADL, self-efficacy score greater than 75, Folstein Mini-Mental State Examination (MMSE) score of 28 or better, high mobility, score in the best third of timed physical performance, fewer than five medications, and good nutritional status. In multivariable analysis, four factors were independently associated with ADL recovery-age 85 years or younger (adjusted RR 4.1; 95% CI 1.3, 13), MMSE score of 28 or better (RR 1.7; 95% CI 1.2, 2.3), high mobility (RR 1.7; 95% CI 1.0, 2.9), and good nutritional status (RR 1.6; 95% CI 1.0, 2.5). CONCLUSIONS: Once disabled, few persons older than 85 years recover independent ADL function. Intact cognitive function, high mobility, and good nutritional status each improve the likelihood of ADL recovery and may serve as markers of resiliency in this population.

Self-report versus state records for identifying crashes among older drivers.

BACKGROUND: There is growing concern about the potential safety implications of the increasing number of older drivers. A primary consideration in determining risk is the method of outcome ascertainment. In the case of motor vehicle crashes, the two most common methods are self-report and state records of events. METHODS: The self-report of motor vehicle crashes was compared to state records among all active drivers (n = 358) in a representative cohort of community-living individuals age 72 years and older in New Haven, Connecticut, in 1989. In the baseline interview, participants who reported driving were asked if they had had any crashes in the previous year. This was compared to state-recorded crashes over the same period. RESULTS: Of the 358 drivers, 33 either reported or had a state record of a crash in the previous year. Of the 33, 20 were identified by self-report only, 9 by both self-report and state records, and 4 by state records only. In the two cases where license reexamination was requested by the officer at the scene, both drivers reported the event in the interview. CONCLUSIONS: Self-report and state records provide complementary information for the ascertainment of crashes among older drivers, although in this sample self-report yielded more events.

Driving cessation and increased depressive symptoms: prospective evidence from the New Haven EPESE. Established Populations for Epidemiologic Studies of the Elderly.

OBJECTIVES: The purpose of this study was to determine the association between driving cessation and depressive symptoms among older drivers. Previous efforts in this area have focused on the factors associated with cessation, not the consequences of having stopped. DESIGN: Cohort study. SETTING: Urban community. PARTICIPANTS: A driving survey was administered in 1989 to surviving noninstitutionalized members of the New Haven Established Populations for Epidemiologic Studies of the Elderly (EPESE) cohort. Of 1316 respondents, 502 were active drivers as of 1988, 92 had stopped driving between 1982 and 1987, and the remainder had either never driven or had stopped before 1982. MEASUREMENTS: Information about independent and dependent variables other than driving status came from the in person EPESE interviews in 1982, 1985, and 1988, except for medical conditions, which were updated yearly. Depressive symptoms were assessed by the Centers for Epidemiologic Studies-Depression (CES-D) scale. Analyses focused on the changes in depressive symptoms before and after driving cessation. Repeated measures multivariable analysis accounted for the effect of cessation on the outcome adjusting for the potential confounding due to sociodemographic and health-related factors. RESULTS: Individuals who stopped driving exhibited substantial increases in depressive symptoms during the 6-year interval. Driving cessation was among the strongest predictors of increased depressive symptoms (Coefficient 2.464, SE 0.758, P = .001) even when adjusting for sociodemographic and health-related factors. CONCLUSIONS: Driving cessation was associated with an increase in depressive symptoms even when accounting for sociodemographic and health-related factors. These consequences need to be taken into account when advising older drivers and when developing alternative transportation strategies.
