Early Hospital Readmission: An indicator of hospital quality of care assessment

Abstract

Background: Early hospital readmission is an indicator of hospital quality of care. It is important to assess readmission risk factors, as it imposes additional burden on patients, families and high cost to healthcare system. Objectives: To define the characteristics of patients with early readmission to a university hospital. Methods: Selection of all patients readmitted in 7 days after hospital discharge from January to March of 2007. Results: All 5363 patients admitted were assessed. 135 (3%) adults and 71 (7%) children were readmitted in 7 days. Most of them were males, with previous admission in the last 3 months with the same diagnosis. Specialities with most common readmission tax in adults were internal medicine (9.7%), hematology (9%), cardiology (5.7%), adult emergency (5.5%), gastroenterology (5%) and general surgery (2.2%). Main causes of adult readmissions were cardiovascular disease (20), gastrointestinal disease (18), respiratory disease (17), cancer (17) and urinary tract disease (13).  Most common co-morbidities in adults were hypertension (39%), diabetes (24%), smoke (18.5%), renal failure (17%), ischemic heart disease (16%), chronic obstructive lung disease (16%) and heart failure (15%). Pediatric readmissions were mainly on oncology population (42.4%). Adults had co-morbidities rate of 2.7. Thirteen percent of children and 5 % of adults died during readmission. Conclusions: Patients characteristics may identify those at higher risk of early readmission. Most of them had multiple medical co-morbidities or had oncologic diagnosis. These findings reflect the chronic condition of patients admitted to our institution.
