Introduction:

Chronic diseases greatly impact the quality of life of patients, either due to their inherent characteristics or due to the derived complications that cause recurrent emergencies.

Objective:

To predict the days of hospitalization until the outcome of patients with chronic disease admitted to a Peruvian public hospital.

Methods:

A descriptive, retrospective and cross-sectional investigation was carried out from July to August 2022, with 488 patients with chronic disease admitted to Cajamarca Regional Teaching Hospital. Admission demographic data and type of patient diagnosis were provided by the hospital statistics office. The univariate analysis was performed with absolute and relative distributions, along with their 95% confidence intervals and the prognostic relationship with Log Rank (Mantel-Cox) - chi square, Kaplan-Meier survival analysis (p < 0.05) and mortality tables.

Results:

53.1% of patients were women, with average age of 67.1 years, who were admitted to the hospital through the Emergency Service (66.0%) and chronic disease was the main cause (79.1%). The average hospitalization time was 67.5 days, with greater number in high blood pressure (63 days). The numerical differences in hospitalization time, according to chronic disease, are not reflected at a statistical level (p = 0.130). Deaths occurred within the first month of hospitalization.

Conclusion:

The days of hospitalization until the outcome are not independent of the patients' chronic illness, since in both cases deaths can occur if their clinical characteristics are irrecoverable.
