An objective scale for measuring discomfort in noncommunicative patients with advanced Alzheimer's disease was empirically generated from the perspectives of nursing staff practicing on special care Alzheimer units and was judged to have content validity. On the basis of a pilot test, the discomfort scale was reduced to nine items. Quantifiable scoring procedures and a rater training program were developed. The scale (DS-DAT) was tested longitudinally for 6 months with 82 subjects at two sites. Psychometric properties, measurement issues, and recommendations for use in practice and research are discussed.

A placebo-controlled crossover design, with each treatment period lasting 6 weeks, was used to investigate effects of dronabinol in 15 patients with a diagnosis of probable Alzhemer's disease who were refusing food. Eleven patients completed both study periods; one patient who died of a heart attack 2 weeks before the end of the study was also included in the analysis. The study was terminated in 3 patients: one developed a grand mal seizure and 2 developed serious intercurrent infections. Body weight of study subjects increased more during the dronabinol treatment than during the placebo periods. Dronabinol treatment decreased severity of disturbed behavior and this effect persisted during the placebo period in patients who received dronabinol first. Adverse reactions observed more commonly during the dronabinol treatment than during placebo periods included euphoria, somnolence and tiredness, but did not require discontinuation of therapy. These results indicate that dronabinol is a promising novel therapeutic agent which may be useful not only for treatment of anorexia but also to improve disturbed behavior in patients with Alzheimer's disease.

A survey of institutionalized patients with clinical diagnosis of probable dementia of the Alzheimer type (DAT) indicated that 21% of patients developed seizures after the onset of DAT. Of the total of 27 patients, 11 developed seizures at home and 16 after institutionalization. In 9 of the 11 patients (82%), who suffered the initial seizure at home, the patients'' condition suddenly worsened and required long-term care admission within 6 months of the seizure onset. Language function declined significantly more rapidly in 5 patients with seizures than in controls matched by age and duration of DAT.

Results provide a formula which can be used to predict likelihood of dying within 6 months following onset of a fever in DAT patients. This statistical prediction is recommended for use in combination with clinical judgment to certify DAT patients for Medicare hospice coverage.

Aggressive medical treatment of infections does not affect the progressive course of dementia of the Alzheimer type (DAT) and has limited effect on the mortality rate. Utilization of health care resources and discomfort during a fever episode were compared in three differing treatment conditions: in 18 patients in a dementia special care unit (DSCU) who received palliative management, 26 patients in a DSCU who were treated aggressively, and 17 DAT patients in traditional long-term care units who were treated aggressively. Both groups of patients in the DSCU had lower discomfort scores, lower utilization of high-cost health care resources, and higher utilization of analgesics and narcotics. A nursing model of care incorporating hospice concepts into the DSCU is suggested.

Psychosocial stress due to the experience of hospitalization was ascertained for 535 medical and surgical patients in a community hospital, using a Hospital Stress Rating Scale, Medical-surgical differences along nine dimensions of stress as measured by this scale were examined, using analysis of covariance to control for the effects of patient characteristics known to be associated with scores on the Hospital Stress Rating Scale. The controlled variables were age, education, number of previous hospitalizations, number of years since last hospitalization, and seriousness of illness (Seriousness of Illness Rating Scale). The analysis of covariance results indicated higher perceived stress for surgical patients on the dimensions of unfamiliarity of surroundings, loss of independence, and threat of severe illness. Medical patients scored higher on the dimensions of stress due to financial problems and lack of information. The authors discuss how these findings might be incorporated in experimental studies designed to reduce stress among hospital patients.
