title: Effect of nursing home characteristics on residents' quality of life: a systematic review.
abstract: The association between nursing home (NH) characteristics and residents' quality of life (QOL) has not been systematically reviewed. This study synthesizes published evidence about the association between NH ownership, affiliation, location, chain membership, percentage of private rooms, facility size, and staffing with residents' QOL. We searched Medline, Web of Science, CINAHL, and Scirus for primary studies published between 1960 and March 31, 2012. We critically appraised risk of bias according to study design, QOL measurements, and adjustment for residents' characteristics. We analyzed the statistical and clinical significance, direction and magnitude of the association. From 1117 citations retrieved, we found one longitudinal quasi-experimental and 10 cross-sectional eligible studies. Variability in the NH characteristics reported and QOL measurements precluded meta-analysis. Studies with low and medium risk of bias (ROB) suggested that nonprofit NHs resulted in better QOL for residents. The low ROB study indicated that in certain QOL domains, rural facilities and facilities with a higher percentage of private rooms were associated with better self-reported resident QOL. All low and medium ROB studies found that RN, LVN/LPN and total nursing staff had no significant relationship with QOL. One longitudinal quasi-experimental study indicated that the Green House with individualized care had better QOL than conventional NHs. The available evidence does not permit strong conclusions about the association between NH characteristics and residents' QOL. The evidence does, however, raise questions about whether NH structure alone can improve residents' QOL and how residents' QOL should be measured and improved.
