Lessons in long-term care: the benefits of a northern exposure.

Canada stands as an important lesson for the United States. At the very minimum it represents the art of the possible. For those interested in long-term care, it suggests that it is possible to include long-term care in a programme of universally accessible care without national bankruptcy. Although Canada has brought medical and social services closer together and has brought acute and chronic care under the same aegis, not all the problems of coordinating such efforts have been solved. For others, the Canadian example shows that care can be provided to all persons who need it without creating uncontrollable expenses or removing families' motivations to care for their own. In so doing, universal coverage creates the opportunity for better coordination of services and ultimately for more efficient care.

Computerized assessment in neuropsychology: a review of tests and test batteries.

This article contains detailed reviews of 13 computerized neuropsychological and performance test batteries and six stand-alone computer tests. Tasks found on these instruments are described and tables illustrate which batteries employ which measures. In addition to issues of reliability and validity, special considerations apply to computerized assessment. These issues are discussed and readers are provided information to help them assess computerized tests in relation to their particular clinical and research needs. Since many computerized tests were developed as performance assessment tools, the relationship between performance and neuropsychological assessment is examined.

Longitudinal study of psychotropic drug use by elderly nursing home residents.

In this longitudinal study of patterns of use of psychotropic drugs by a cohort of elderly nursing home residents (N = 5,752), drug use was examined upon admission, 3 months later, and at discharge/end of study. At each time point, 17% of the cohort used neuroleptics. Half of the subjects discontinued neuroleptics at each time point; however, a similar number were initiated on the drug. Benzodiazepines were used by 21%, 15%, and 15% at each of the three time points, respectively. Twice as many people were taken off benzodiazepines as initiated on them following admission. The 5% rate of antidepressant use was constant across the three time periods, although only half of those who took antidepressants upon admission were also taking them upon discharge/end of study. The amount of change due to discontinuation of these drugs and adjustment in dosage levels challenges the stereotype of the "neglected psychotropic drug user" in nursing homes.

Qualitative analysis of the Program of All-inclusive Care for the Elderly (PACE).

The innovative model of capitated acute and chronic care for nursing-home-eligible elderly persons, which was developed at On Lok in San Francisco's Chinatown and stresses using community care in lieu of institutional care, has been replicated at eight sites around the country. The early experience in developing these sites tests the extent to which the principles of this approach, based on day health care, can be reproduced in a variety of other settings. Four of the eight sites have begun formal capitated care; enrollment has been less active than anticipated, apparently due to reluctance to change physicians and resistance to day care.

Acute Disease

Self-report versus medical record functional status.

The importance of assessing functional status in the hospitalized patient is gaining recognition. However, the availability and accuracy of medical record functional status data are uncertain. We collected data on 2,504 patients greater than 65 years of age discharged alive. A personal interview conducted 2 days before discharge recorded the patient's self-reported ability to perform 5 activities of daily living scales. Medical record abstraction was used independently to determine ability to perform the same activities of daily living scales. Patients who required any human assistance to perform a function were considered dependent. Patients were also contacted after discharge to determine the site of posthospital care (28% discharged to a nursing home). The amount of missing medical record functional status data varied by function from 20% for bathing to 50% for dressing. Ten percent of patients had no medical record functional status documentation concerning any of the five functions. The prevalence of self-reported dependence at discharge varied by function from 24% for feeding to 93% for bathing. The total number of dependencies differed between the two methods (medical records, 2.3 +/- 1.9; self-report data, 3.2 +/- 1.5). There was exact agreement between the two methods on the total number of dependencies in 28% of cases and differences of greater than or equal to 3 in 20%. In a stepwise logistic model predicting discharge to a nursing home and adjusting for other relevant variables, the number of dependencies as determined by self-report and medical record data each remained significant (Odds Ratios = 1.6). Self-report and medical record functional status data differ substantially, and the medical record data remain independently associated with nursing home placement. Several possible explanations for this finding are explored.

Inadequate treatment of depressed nursing home elderly.

OBJECTIVE: To determine the prevalence of antidepressant drug treatment among nursing home elderly with major depression. DESIGN: Survey early and late in nursing home stay. SETTING: Sixty Medicaid/Medicare-certified skilled nursing homes. PARTICIPANTS: Admission cohort of 5,752 residents age 65 or older in 1976 through 1983. MEASURES: Chart review by nurse-abstractors of physicians' diagnoses, drug used, and alertness rating. Diagnosis of depression equivalent to DSM-III-R major depression. RESULTS: Of 868 persons with a diagnosis of depression in the medical record, only 10% were treated with antidepressant drugs. More received neuroleptics and benzodiazepines than received antidepressants, but most (52%) received no psychoactive drug at all. A subset of 258 depressed persons had positive notations in their records supporting a mental status rating of "alert and oriented." Of that subset, only 15% received antidepressants. When followed from admission to discharge or end of study the prevalence rate of antidepressant drug treatment increased by 4%. CONCLUSIONS: In the late 1970's and early 1980's, even when the primary care physician made and recorded a diagnosis of depression, most such nursing home residents remained untreated, incorrectly treated, or inadequately treated.

Improving primary care in nursing homes.

We conducted a quasi-experiment to evaluate the impact of a Medicare waiver which allowed the use of nurse practitioners (NPs) and physicians assistants (PAs) to deliver primary care to Massachusetts nursing home patients and removed the limits on the reimbursable numbers of visits per month. A carefully matched set of 1,327 Medicaid patients from 95 non-participating homes in the same areas of Massachusetts was compared to 1,324 Medicaid demonstration patients from 75 homes. Information came from specially designed record reviews and the Medicaid and Medicare information systems. Separate analyses were done for newly admitted cases and rollovers. Comparisons of quality of care suggested that the medical groups using NPs and PAs provided as good or better care than did the physicians in the control group. There were no differences in functional status changes or in the use of medications. The demonstration patients received more attention, as reflected in more orders written and an average of one additional visit a month. Demonstration patients showed higher scores on three of seven specially designed quality tracers, congestive heart failure and hypertension for both new administrations and rollovers, and new urinary incontinence for new admissions. Rollovers had significantly fewer emergency and total hospital days. A cost analysis suggests that the use of NPs and PAs saves at least as much as it costs and may save additional money with more sustained use.

Cardiovascular effects of exercise in hamsters with experimental thiamine deficiency.

The hemodynamic effects of daily treadmill exercise were evaluated in hamsters with experimental thiamine deficiency to test the hypothesis that increased energy consumption might be a contributory factor in the pathogenesis of beriberi heart disease. Daily exercise enhanced thiamine deficiency and was manifested by earlier development of symptoms of neuropathy compared to non-exercised animals. Hemodynamics of exercised thiamine deficient animals were characterized by significantly lower O2 consumption, lower cardiac output, and lower left ventricular minute work, compared to exercised, pair-fed control animals. Left ventricular end-diastolic pressure was slightly but not significantly higher in thiamine deficient animals. Left ventricular function, therefore, was depressed in this group. There was no evidence of hyperkinetic circulation, cardiomegaly or congestive heart failure. Neuropathy and depressed ventricular function, characteristic of pure thiamine deficiency, were observed in the absence of high cardiac output or high output failure, the pathogenesis of which may require other unknown factors.

Care of the aged: old problems in need of new solutions.

Long-term care for the aged in the United States is overly dependent upon the nursing home. This hospital-like model for long-term care is particularly inappropriate since it imposes a medical solution on a variety of social problems. An adequate long-term care program requires a range of resources in the community as well as in institutions; sheltered housing options seem a desirable alternative to the nursing home. To ensure the quality of nursing home care, the present focus on setting standards for care activities should be abandoned in favor of a focus on care outcomes (physical, mental, and social). In an effort to change our present perverse incentives in the nursing home industry, the proposal is made that nursing homes be reimbursed according to the degree to which patient outcomes meet predicted outcomes.

Effects of adding a Medex on practice costs and productivity.

Archival data on ten rural practices employing a Medex and on ten matched controls were compared to determine changes in the volume of patients seen and changes in the practice finances before and after the employment of a Medex. There were no significant differences in the changes in patient volume; however, the practices that employed a Medex showed an increase in revenue and in net profit per physician. On the average, the net profit increased approximately $11,000 (22%) for the physicians with Medex, compared with $9,000 (21%) for the control physicians.

Costs and Cost Analysis

Differences in the outcomes of acute episodes of care provided by various types of family practitioners.

This study was designed to compare the outcomes achieved in a series of acute care episodes by different levels of family practice providers working in the clinic setting. The study utilizes a method which depends upon the provider to estimate level of function expected and earliest date of recovery for each episode. When the patients are viewed as a single group, those patients treated by the medex appear to fare considerably better and those seen by a faculty member do worse; however, when each functional status group is examined separately, only the asymptomatic but clinically ill patients (45 cases) show a statistically significant difference in outcomes among the providers, with the medex having good results and the faculty poor results.

Toward the measurement of primary care.

The renaissance of rhetoric about primary care--"continuous, coordinated, comprehensive, family-centered"--has paralleled the growth of entrants into formal training programs. The extent to which primary care is actually practiced this way has not been examined, nor have the routes to preparing for it. A preliminary set of measurements is suggested.
