Introduction:

The study of comorbidity requires a multilateral approach with a view to improving the quality of care for these patients by the care system.

Objectives:

To explore the magnitude of the comorbidity of chronic diseases in adults admitted to hospitals.

Methods:

Prospective-observational-longitudinal-analytical study. Patients hospitalized in a medical clinic room or clinical patients in indiscriminate hospitalization rooms are included, Multicenter study in 42 centers, with 2 years of recruitment. Consecutive sampling. Descriptive, inferential and regression statistics.

Results:

5925 recruited, male gender 50,3%, age 60,66 ± 0,25 years, main origin from the guard 73%, stay 12,61 ± 0,24 days, longer in surgical (15,45 ± 0,67 vs 11,76 ± 0,23, p < 0,00001), 23% received surgical treatment. Main educational level: complete secondary school 21,6%. Economic difficulties: 20%, mortality 9,26%, prevalence of dyslipidemia, diabetes and hypertension: 22,53%, 28,82% and 51,86% with 473 new diagnoses in said pathologies, BMI: 27,88 ± 0,65, Global Charlson 2,09 ± 0,02 and in deaths 3,84 ± 0,11. The average number of pathologies per patient was 2,14 ± 0,01 and increased with age (p value for linear regression < 0,00001).

Conclusions:

Hypertension, diabetes and dyslipidemia represented the most prevalent entities in the clinical hospitalization room, cardiovascular, respiratory, infectious, oncological, neurological, metabolic and nephrological diseases were independent predictors of mortality.
