Introduction: Noise pollution is known to cause deleterious effects on human health and may especially affect frail elderly patients with poor mental and physiologic reserve.Aims Of the Study: (i) to learn levels and time- and place-patterns of noise in an urban community teaching hospital (TH) and affiliated urban nursing home (NH); (ii) to compare levels and patterns of noise in both institutions.Results: Recordings were obtained in three areas of the TH: emergency room (ER), intensive care units (ICU), and medical-surgical floors (HF) - nurses' stations and patients' rooms. On nursing home floors (NHF), noise levels were recorded at nurses' stations and in patients' rooms. In all areas of the hospital and NH, noise levels were in range of 55-70 dB and exceeded the 40-50 dB limit recommended by the EPA. In ER and ICU, noise level was higher on weekdays than weekends. In ICU and on HF, noise level was higher during mid-day hours during mornings and evenings. The highest noise level was recorded in ER followed by ICU and HF. On HF, nurses' stations were noisier than patients' rooms. Noise level was higher in the TH than in the NH. On NHF, noise level was similar on weekdays and weekends. Noise was stronger at nurses' stations than in patients' rooms and stronger in the mornings and evenings than during mid-day hours. Patterns of noise followed the human factor activities observed in both facilities.Conclusions: The level of noise in both facilities was above the recommended limit and presents an environmental stressor for a frail elderly patient. With transfer from NH to TH exposure to this stressor is increased. Time- and place-patterns of noise in both institutions suggest that human factor is a major source of noise pollution. This pollution is, therefore, potentially modifiable. [ABSTRACT FROM AUTHOR]

Background: Chronic constipation is a common and bothersome problem in elderly nursing home patients. Although fibre has a known role in the treatment of constipation, laxatives are still widely used in nursing home patients.Objective: To determine whether the addition of a fibre supplement to oral diet can reduce the use of laxatives in a long-term care facility.Participants and Methods: Oral diet of 92 nursing home residents (all older than 65) on chronic laxatives (docusate, milk of magnesia with Cascara, psyllium) was supplemented with 'Fiber 7', a natural powder fibre (7 g per meal twice a day). During the next 2.5 years discontinuation of laxatives was attempted.Results: Laxatives were successfully discontinued in 63 of the 92 patients (68.5%, 95% confidence interval 59-78%). The fibre supplement was well tolerated. The cost of care was decreased by dollar 3.5 per patient every month or by dollar 220/month for the 63 patients.Conclusions: Use of 'Fiber 7' allowed discontinuation of laxatives in 63 of 92 nursing home residents. The fibre supplement was a safe and convenient alternative to laxatives and decreased the cost of medical care. [ABSTRACT FROM AUTHOR]
