Evaluation of HSMR in Sweden A project initiated by the National Board of Health and Welfare, the Federation of County Councils and the Southeast health care region. A national interest to use HSMR to compare hospitals and county councils A possible indicator for comparison of the Nordic countries?
Swedish Hospital Discharge Register started in the 1960:s. Since 1987 it covers all public, in-patient care in Sweden Data on patient : Personal id-number, sex, age, place of residence Data on hospital: County council, hospital, department Administrative data Date of admission/discharge, LoS, acute/planned admissions, admitted from, discharged to Medical data Main and secondary diagnoses, surgical procedures, external cause of injury and poisoning
HSMR in Sweden Variables: Sex Age Length of stay Way of admission, transfer from other hospital Acute/planned admission Main diagnosis
HSMR in Sweden Main diagnosis The main diagnoses accounting for 80 % of hospital mortality 58 diagnoses 370 000 admissions yearly, ~ 25 % of all admissions 27 000 deaths annually
HSMR in Sweden Discharged as dead Good quality 27 000 registrations per year 30 days mortality ??

HSMR in Sweden Data quality problem: Transfer within hospital (1,2 - 10,1%) Transfer between hospitals (2,2 - 43,5%) Underreporting planned/not planned Large vs. small hospitals?
HSMR in Sweden Future steps: Present the method and publish preliminary results on county council level in the Swedish Medical Journal Discuss data quality with those responible on county council level Consider to use HSMR as a national indicator Pilot project in the South-east healthcare region on structured patient record review on hospital deaths with IHIs Trigger Tool
