Introduction:
The in hospital mortality is a marker of health care quality. It can be evaluated according by the principal diagnosis of disease or by Diagnosis Related Groups (DRG).
Objectives:
Know and to analyze the in hospital mortality and mortality rate (MR) in the patients admitted in the Hospital Morales Meseguer (Murcia) of II level of the INSALUD during 1999.
Methodology:
Study of the minimum basic group of data into the hospital.
Results:
The MR was 3.8% of 508 deaths analyzes, 56.7% corresponded a male. The MR was equal in male (3.6%) and females (3.9%). The medium of age into deaths was 77 years. The numbers of deaths inpatients under 80 years was higher in males (n = 197; 65%) than in lower in female (n = 102; 35%)(p = 0.002). The addition of deaths of Internal Medicine and Intensive Care Unit represent a 70% of cases of deaths occurred in the hospital. The MR was higher in Intensive Care Unit (10.5%) followed by Hematology (6.9%) and Internal Medicine (6.1%). Ten DRG represents of 50% of the causes of deaths, and all of them were DRG of medical categories. The DRG more frequents was 541, Respiratory disorders with complication (n = 61, MR 12.8%), followed by DRG 533. Specific cerebrovascular disorders without Transit isquemic accident (n = 33; MR 34.7%), DRG 123 Acute myocardical infarction (AMI) with death (n = 31; MR 100%), DRG 014 Others disorders of nervous system (n = 27; TM: 10.3%) y DRG 552 Disorders of digestive tract without esophagitis, gastroenteritis and not complicated ulcer (n = 27; MR: 31.0). The main diagnostic more frequent was cerebrovascular diseases (n = 60, MR 12.2%), pneumonia-bronchopneumonia (n = 52, MR 10.9%), chronic obstructive lung disease (n = 36, MR 7.1%), AMI (n = 33, MR 11.5%), and neoplasia of digestive tract (n = 26; MR 8.5%). The MR of woman with AMI (19.5%) was higher than man (7.7%) (p = 0.005), the MR in woman with abdominal hernia (4.3%) was higher than man (0.6%) (p = 0.01), and MR of pyelonephritis and urinary infection in man (4.9%) was higher than woman (0%) (p = 0.008).
Conclusions:
The mortality and MR by DRG and main diagnostic is an indicator than permit to know and monitoring the quality of health care.
