Environmental Determinants of Quality of Life in Nursing Home Residents with Severe Dementia Authors: Game Olmo Jo Lopez-Pousa Secumdinoi Turon-Estrada, Antoni 1.2.3 Juvin Dolors Ballester, David Vilalta-Franch, Joan 1,2,3 Source: Journal of the American Geriatrics Soci Jul2012, Vol. 60 Issue 7, p1230-1236. 7p. 4 objectives: To detemine the relationship between qualityof life (QOL and environmental factors of temperature, noise, and lighting in nursing home residents with severe dementia. Design Cross-sectional, observational, analytical. Setting Eight public, long-tem care nursing homes in the province of Girona, Spain. Participants Random sample of 160 musing home residents with severe dementia. Measurements Functional and cognitive impairment, pain, neuropsychiatric disturbances, and QOL were detemined using standardized instruments. Temperature, noise, and lighting in bedrooms dining rooms, and living rooms were measured in the moming and aftemo using a multifunction environment meter in a standardized manner. on Results Adjusted multivariate linear regression models demonstrated that environmental measures were independently associated with QOL, and related factors. High temperature in the bedroom was associated with lower QOL (standardized B 0.184), high noise levels in the living room were associated with low behavioral signs of social interactions (A -0.1960, and low lighting levels in the bedroom. were associated with number of signs of negative affective mood -0.135). Conclusion The QOL of nursing home residents with severe dementia was related to environmental factors such as temperatuure, noise, and lighting. The monitoring of these environmental factors may improve these individuals' QOL. [ABSTRACT FROM AUTHOR]
Explanation / Answer
a) Research question : Is there a relationship between Quality of Life(QOL) and environmental factors like noise, temperature and lightining in nursing home residents with severe dementia
b) This is basic research as a random sample of nursing home residents is selected and measurements are taken.
c) It is an observational and anaytical study. It is not experimental design as we are not carrying out any experiment.
d) The unit of analysis is QOL(Quality of Life). 160 nursing home residents were analyzed. So the number of observations is 160.
e) The sample was chosen randomly.
