Evaluating home environments of persons with dementia: interrater reliability and validity of the Home Environmental Assessment Protocol (HEAP).

PURPOSE: This article reports on an interrater reliability and preliminary validity study of an investigator-developed tool, the Home Environmental Assessment Protocol (HEAP) for use in homes of persons with dementia. METHOD: The HEAP consists of 192 items that are summed into separate indices representing the number of hazards, adaptations, and level of clutter and comfort in eight areas of the home. Interrater reliability was examined among four raters, two environmental experts and two non-experts, who observed 22 dementia households. RESULTS: The Kappa statistic was used to evaluate agreement level for each measured item and found that agreement ranged from slight to almost perfect. Intraclass correlations (ICCs), were used to evaluate agreement level for indices. The hazard index in each room ranged from fair (0.36) to moderate (0.66) for all raters. For the adaptation, clutter and comfort indices in each room, ICCs ranged from 0.51 to 0.90 for all raters. Agreement level between expert and non-expert raters differed minimally for all indices. Adaptations to dining rooms (r= -0.080, p = 0.001), kitchens (r = -0.52, p = 0.02) and bedrooms (r = -0.76, p = 0.001) were associated with patient deficits such that more adaptations were made in homes of dependent persons. Low Mini-Mental Status Examination scores were associated with fewer hazards, more adaptations, and less clutter. CONCLUSION: Findings show that both experts and non-expert raters use the HEAP consistently. Also, measured attributes are related to cognitive and functional status in the expected direction.

Dehydroepiandrosterone sulfate and psychiatric measures in a frail, elderly residential care population.

BACKGROUND: Previous reports have found low levels of dehydroepiandrosterone sulfate (DHEA-S) in association with physical illness, and with frailty in the elderly. In a preliminary study, we also found low DHEA-S associated with increased disability and number of pain sites. However, we found the opposite relationship between DHEA-S and cognitive impairment. Therefore, we conducted a study of a second sample to confirm this unexpected finding and the expected inverse correlations between DHEA-S levels and increased disability and number of pain sites. METHODS: Psychiatric symptoms and disorders were correlated with DHEA-S and related steroid levels in a second convenience sample in the nursing home population. RESULTS: This sample confirmed the previous finding of a positive association of cognitive impairment with higher DHEA-S levels but the inverse association of DHEA-S levels with the numbers of pain sensations did not reach statistical significance. Cognitive impairment was also positively associated with higher dehydroepiandrosterone (DHEA) and estradiol levels (women only). Cortisol levels were inversely associated with depressive symptoms. CONCLUSIONS: The anomalous positive correlation between cognitive dysfunction and DHEA-S levels, and the inverse correlation between cortisol levels and depressive symptoms, suggests that the relationships between psychiatric symptomatology and levels of steroids that are part of the hypothalamic-pituitary adrenal axis are different in the frail elderly population from that of younger and heartier populations.

Dehydroepiandrosterone sulfate (DHEA-S) and psychiatric and laboratory measures of frailty in a residential care population.

Previous reports have found low levels of dehydroepiandrosterone sulfate (DHEA-S) in association with frailty in elderly patients. The mechanisms underlying these associations are not known. Therefore, psychiatric symptoms and disorders that are common in frail elderly patients were correlated with DHEA-S levels in a convenience sample selected from a nursing home population. Low DHEA-S levels were associated with high degrees of self-rated disability and insomnia. In women, low DHEA-S levels were also associated with increased numbers of pain sites. However, cognitive impairment was associated with higher DHEA-S levels in women. Thus, in frail elderly patients, there are contradictory relationships between DHEA-S and neuropsychiatric measures of frailty (cognitive impairment, disability, insomnia, and number of pain sites), and there may also be gender differences in these relationships.

Alcohol abuse: a source of reversible functional disability among residents of a VA nursing home.

The prevalence of psychiatric disorders was determined in a sample of 196 VA nursing home residents who were interviewed using the modified Schedule for Affective Disorders and Schizophrenia (mSADS). Of the 160 subjects for whom data were available, 86% had a diagnosis of at least one psychiatric disorder. The prevalence of clinically significant cognitive impairment was 60.6% and of major depression 13.8%. Of 110 residents for whom alcohol histories were obtained, 32 (29%) had a lifetime diagnosis of alcohol abuse. The degree of impairment in activities of daily living improved significantly from the time of admission to the time of the evaluation (average 1.4 years) among those who were recently abusing alcohol compared to those who formerly abused alcohol and those who never abused alcohol. The effect is clinically as well as statistically significant and has the potential benefit of reducing caregiver burden and health care costs for the elderly.

Educating allied health professionals to provide care for cancer patients and their families.

From 1985 to 1988, a state-wide program of cancer education was offered to community-based allied health professionals (AHPs) at five different program sites in Pennsylvania. During this three-year period, 512 social workers, clergy, dieticians, physical therapists and others received training to increase their knowledge about cancer and counseling, improve their supportive attitude regarding cancer patients and families, and decrease stress related to their work with this population. Overall, the Program was successful in reaching AHPs working with cancer clients who had little formal training in the cancer field. At the beginning of training, it was observed that AHPs with initially higher levels of education and more years of work experience with cancer patients had higher levels of counseling knowledge. Those who were women, worked in hospitals, or had worked with cancer patients longer exhibited higher levels of cancer knowledge. Participants who were women and who had more education had reported lower levels of job stress. Among those AHPs who completed the training courses, cancer knowledge increased by 14 percent. In addition, knowledge related to counseling cancer patients and their families improved by 11 percentage points. Perceived job stress among the AHPs also declined by 10 percent. Finally, participant supportive attitude concerning cancer clients improved.
