Self-feeding dependence incidence and predictors among nursing home residents: Findings from a 5 year retrospective regional study

The aim of this regionally-based, retrospective study was to describe the incidence of self-feeding dependence and predictors among elderly patients admitted from 2008 to 2013 to 105 Italian nursing homes. Data reported in a regional database collected at the time of nursing home admission and every 6 months up to the resident's death were accessed. The self-feeding degree of dependence was the dependent variable; at the individual and nursing home levels, explanatory variables were those collected at nursing home admission and every 6 months. The structural equation model and the ordinal polynomial logit regression analysis were performed. A total of 13 175 records of residents when admitted to the nursing home and their following 69 341 records, were included. At the time of nursing home admission, 6496 residents (49.3%) reported a certain degree of dependence in self-feeding and showed slight worsening in their dependence every 6 months. At the individual level, the increased functional dependence raised the proportional odds ratios of approximately 4.36 times of an increased dependence in self-feeding; the degree of cognitive impairment, the lack of social interactions, the occurrence of pressure sores, comorbidities, as well as the clinical instability and time all raised the risk of self-feeding dependence progression. At the nursing home level, an increased number of beds emerged as a factor also increasing the proportional odds of dependence in self-feeding. Factors affecting self-feeding dependence are multi-faceted at the individual and at the nursing home levels.
