BANON GUTIERREZ, Sonia; GASCON CATALAN, Ana  and  CABRERIZO GARCIA, José Luis. Living in nursing homes. Prognostic factor of mortality in respiratory infections?. Medicina (B. Aires) [online]. 2021, vol.81, n.5, pp.754-760. ISSN 0025-7680.

Respiratory infection is one of the most frequent diagnoses associated with high mortality. Living in a nursing home could be a predictive risk factor for mortality. The objective was to study the characteristics of patients with respi ratory infection according to whether they came from their home or nursing homes, and to analyze whether their origin is a risk factor for mortality. It was a prospective cohort study, that included 208 patients with respiratory infection admitted to the Internal Medicine Service, that participated in the study. Clinical, analytical, epidemiologi cal, prognostic and therapeutic variables were collected and a multivariate analysis was performed. Patients had an average age of 83 years and 64.9% came from their home. 44.7% had heart failure as a clinical history. Most of patients met criteria of pluripatology, polypharmacy and were moderately dependent according to Barthel’s index. Mortality at admission was 16 patients (7.7%), and during the six-month follow-up of 37 patients (17.8%). Those coming from nursing homes had a higher mortality rate, 37%, than those who lived in their own home, 19.3% (p = 0.005). In the multivariate analysis, the prognostic factors for mortality were a higher level of urea at admission (OR = 2.33, IC 95% = 1.06-5.11) and the non-prescription of oxygen at discharge (OR = 2.96, IC 95% = 1.29-6.82). In conclusion, a higher percentage of mortality is observed in patients coming from nursing homes, however further research is needed to clarify whether living in a residence for elderly can be considered an independent risk factor for mortality.
