The study's main objective was to assess the association between facility ownership and long-term, all-cause mortality. RESEARCH DESIGN AND METHODS: We conducted a mortality follow-up study on a cohort of 611 nursing-home residents in the city Madrid, Spain, from their 1998-1999 baseline interviews up to September 2013. Residents lived in three types of facilities: public, subsidized and private, which were also sub-classified according to size (number of beds). Residents' information was collected by interviewing the residents themselves, their caregivers and facility physicians. We used time-to-event multivariable models and inverse probability weighting to estimate standardized mortality risk differences. RESULTS: After a 3728 person-year follow-up (median/maximum of 4.8/15.2 years), 519 participants had died. In fully-adjusted models, the standardized mortality risk difference at 5 years of follow-up between medium-sized private facilities and large-sized public facilities was -18.9% (95% confidence interval [CI]: -33.4 to -4.5%), with a median survival (95% CI) of 3.6 (0.5 to 6.8) additional years. The fully-standardized 5-year mortality difference (95% CIs) between for-profit private facilities and not-for-profit public institutions was -15.1% (-31.1% to 0.9%), and the fully-standardized median survival difference (95% CIs) was 3.0 (-1.7 to 7.7) years. DISCUSSION AND IMPLICATIONS: These results are compatible with an association between factors related with the ownership of facilities and the long-term mortality risk of their residents. One of these factors, the facility size, could partly explain this association.
