Postdischarge geriatric assessment of hospitalized frail elderly patients.

BACKGROUND: The diffusion of comprehensive geriatric assessment services has been rather limited in North America partly because of reimbursement and organizational constraints. OBJECTIVE: To evaluate the impact of a comprehensive geriatric assessment intervention for frail older patients that is started before hospital discharge and is continued at home. METHODS: Patients older than 65 years were selected who had either unstable medical problems, recent functional limitations, or potentially reversible geriatric clinical problems. Patients (n = 354) were randomly assigned to either the intervention group or a control group. Information on survival, readmissions, nursing home placement, medication use, and health status was collected at 30 and 60 days after hospital discharge. RESULTS: No differences were observed between the two treatment groups in survival, hospital readmission, or nursing home placement by 60 days. After adjustment for baseline characteristics, no significant differences were observed between the two groups on measures of physical functioning, social functioning, role limitations, health perceptions, pain, mental health, energy and/or fatigue, health change, or overall well-being. CONCLUSIONS: Although efficacy has been demonstrated for some forms of comprehensive geriatric assessment, the types of services that are easier to establish (inpatient consultation services and ambulatory assessment) have not been shown to improve outcomes. Our results indicate that outcomes are unaffected by a limited form of comprehensive geriatric assessment begun in the hospital and completed at home. Further efforts are needed to develop and to evaluate realistic approaches to comprehensive geriatric assessment.

Geriatric home assessment after hospital discharge.

OBJECTIVES: To evaluate the feasibility of an intervention involving post-discharge geriatric home assessment and follow-up and to describe the spectrum of significant clinical problems identified during the home assessment. DESIGN: Prospective observational study nested within a randomized controlled trial. SETTING: Inpatient service of a large academic medical center in Southern California. PATIENTS: There were 152 adults aged 65 or greater who had one or more specific risk factors for functional decline or increased mortality, who were awaiting discharge from the hospital, and who were assigned to the intervention arm of a randomized controlled trial of post-discharge comprehensive geriatric home assessment. MAIN RESULTS: During the home assessment, the gerontologic nurse practitioner (GNP) identified new or worsening problems in 150 patients (99%); 61 problems (eg, serum sodium 125 mg/dL; severe orthostatic hypotension) were considered by a reviewing physician to require urgent medical attention. Older age, non-white race, and new incontinence were associated independently with a greater number of findings (P < 0.05). Based on the findings, an interdisciplinary team made an average of 3.4 recommendations per patient; only two of 111 requests for written approval of recommendations were rejected. CONCLUSIONS: Post-discharge visitation by a GNP to patients at high risk is capable of detecting a high yield of important and potentially reversible clinical problems. This multidisciplinary approach is acceptable to physicians. Research is needed to identify additional links between short hospital stays, impairment or instability at discharge, and adverse outcomes.

Alcohol interaction of lormetazepam, mepindolol sulphate and diazepam measured by performance on the driving simulator.

Sixteen healthy volunteers of a mean age of means = 26.4 years took part in a driving simulator test in an eightfold crossover study under double-blind conditions. The additional influence of alcohol was tested acutely after a single administration of 2 mg lormetazepam, a new, highly effective derivative from the benzodiazepine class, 10 mg mepindolol sulphate, a new betablocker without sedating properties, and 10 mg diazepam. All drugs were compared with placebo and the test was performed 1, 2 and 3 hours after oral intake. The aim was to investigate particularly the risks relevant in road traffic caused by simultaneous intake of these substances with alcohol. For this purpose, besides the driving simulator, an accurate reaction test ( WDG ) and self-rating scales were used, the latter in order to assess subjective stress and anxiety levels. Lormetazepam, due to its strong sedating property, showed a reduction in driving performance and an increase in reaction time and pulse rate as compared with placebo, and these effects were highly potentiated by alcohol. Mepindolol sulphate expectedly reduced pulse rate when compared with placebo, otherwise there were no significant differences. Diazepam, when compared with placebo, like lormetazepam caused a reduction in driving performance and reaction capacity and an increase in pulse rate, but intensity and duration of this effect were less than with lormetazepam and did not reach statistical significance. No significant potentiating effects were observed after the additional application of alcohol.

[Lormetazepam in preoperative sleeplessness. Dose dependance of the effect and comparison with 100 mg pentobarbital (author's transl)]. / Lormetazepam bei präoperativen Schlafstörungen. Dosisabhängigkeit der Wirkung und Vergleich zu 100 mg Pentobarbital.

Lormetazepam (0.5, 1, 2, 4, 8 mg)--a new benzodiazepine--was tested versus Pentobarbital (100 mg) under double blind conditions on 240 preoperative inpatients for night-time sedative and side effects after acute oral intake. Results are based on p less than 0.05. Additionally p less than 0.125 in binomial-two-sample-tests was accepted. Lormetazepam shows dose dependent increase in hypnotic effects (e.g. reduction in sleep latency and number of awakenings, increase of total sleep duration), and side effects (e.g. dopiness, dizziness), but no relevant change in vital signs. About 0.5 mg of Lormetazepam are equivalent to 100 mg of Pentobarbital. 2 mg of Lormetazepam seem to be the optimum dose regarding the relation between hypnotic and side effects. In the view of anaesthesists Lormetazepam is preferable to Pentobarbital because of more favorable safety aspects.
