ObjectivesTo apply Wolff's Criteria to hospital discharge records (HDR) in order to detect adverse events worthy of further study.MethodsGynecology and Obstetrics Units of three Sicilian hospitals were considered and HDR regarding ordinary and day hospital admissions in 2008 were collected. A matched case-control study was designed, by random selection of 10 controls at maximum for each case. Matching was performed on the variables age and speciality of admission (gynecology or obstetrics).ResultsOut of a total of 7011 HDR examined, 114 cases were identified with Wolff's Criteria. Multivariate analysis confirmed a statistically significant association with the origin of admission, diagnosis at the acceptance and length of stay: there was a decreased risk of Wolff's event in patients having urgent admission compared to elective (OR = 0.47, 95% CI = [0.28-0.78]), an increased risk in patients reporting tumor (OR = 5:41, 95 % CI [1.89-15.47]) and other causes (OR = 2.16, 95% CI [1.10-4.24]) compared to delivery diagnosis at acceptance and in patients whose length of stay was more than 6 days (OR = 23.17, 95% CI = [12.56-42.7]) compared to less or equal than 3 daysConclusionWolff's Criteria can be applied for the analysis of clinical risk in hospitals with different structural characteristics, on condition that the HDR database is complete and good quality.
