This result shows you how often a patient, older than 18 years, develops a pressure lesion that is large and deep, reaching muscle and bone, while admitted in hospital for a medical or surgical condition. It is reported at a rate per 100 admissions of 3 days or longer. A lower score is better.
The measurement is based on the definitions and methodology published by the Agency for Healthcare Research and Quality (AHRQ).
The data sources: We manually report any issues, including bed sores, in our specifically designed IT system, the Incident Management System (IMS), which we use to track how well we are doing. We use the IMS system for the data on pressure lesions and the hospital billing system, SAP, for the admission and age data.
The measure is calculated by counting the number of stage III and IV pressure lesions, divided by the number of patients, 18 years and older, that were admitted to hospital for a medical or surgical condition multiplied by 100 for the period under review. Obstetric admissions and admissions for less than 3 days are excluded.
