Introduction:

Inadequate hospitalizations (IH) alter hospital management and much more when they are carried out in the elderly population, therefore the identification of factors is relevant at the national and local levels.

Objective:

To determine the factors associated with inappropriate hospitalizations of older adults in the Emergency Service (ES) of the Edgardo Rebagliati Martins National Hospital (HNERM) during the year 2017.

Methods:

Observational, analytical, cross-sectional design study. A sample of 414 patients randomly selected from 18,250 patients admitted in the study period was selected. Data collection forms were used and clinical histories were reviewed. With the help of the SPSS 25 program, the Chi square test was performed and the simple Prevalence Ratio (PR) and adjusted (PRa) were calculated. The significance level was 5%.

Results:

The frequency of inappropriate hospitalizations was 11.8%. The epidemiological factors associated with inadequate hospitalizations were ages from 75 to 84 years (RPa=5.80 [2.20-15.27]) and from 85 to more years (RPa=8.22 [2.76-24.44]). ), the female sex (RPa=2.20 [1.11-3.10]), the occupation as a housewife (RPa=3.39 [1.13-10.17]) and the accompaniment of the spouse (RPa = 9.16 [2.59-32.38]), child (RPa= 3.72 [1.14-12.14]), parents (RPa= 8.50 [1.88-38.44 ]) and siblings (RPa= 22.42 [5.78-86.97]). The organizational factors associated with inadequate hospitalizations were internist treating physician (RPa=2.90 [1.38-6.07)]) and admission morning shift (RPa=4.84 [1.67-14.06)]) .

Conclusions:

There are factors associated with inappropriate hospitalizations of older adults in the SE of HNERM.
