MCHPE is active in health services research, evaluation and policy analysis, concentrating on using the Manitoba health data base to describe and explain patterns of care and profiles of health and illness. Manitoba has one of the most complete, well-organized and useful health data bases in North America. The data base provides a comprehensive, longitudinal, population based administrative record of health care use in the province. Members ofMCHPE consult extensively with government officials, health care administrators, and clinicians to develop a research agenda that is topical and relevant. This strength, along with its rigorous academic standards and its exceptional data base, uniquely position MCHPE to contribute to improvements in the health policy process. MCHPE undertakes several major research projects, such as this one, every year under contract to Manitoba Health. In addition, MCHPE researchers secure major funding through the competitive grants process. Widely published and internationally recognized, they collaborate with a number of highly respected scientists from Canada, the United States and Europe. iv TABLE OF CONTENTS EXECUTIVE SUMMARY ............................................................................................... 1 DEFINITIONS USED IN THIS REPORT .................................................................... 14 INTRODUCTIONS ......................................................................................................... 20 PROCESS ......................................................................................................................... 24 Interqual Criteria ........................................................................................................ 26 Why InterQual? .......................................................................................................... 28 Alternate Levels of Care ............................................................................................. 29 Terms Used ................................................................................................................. 29 METHODOLOGY .......................................................................................................... 30 Sample ........................................................................................................................ 30 Hospitals ..................................................................................................................... 32 Data Collection ........................................................................................................... 34 Communication with Hospitals ........................................................................... 35 Co-ordination and Training. ............................................................................... 3 5 Inter-Rating Reliability ....................................................................................... 35 FINDINGS ........................................................................................................................ 36 Representativeness of the Sample .............................................................................. 36 Admissions ................................................................................................................. 37 Results by Hospital Group ......................................................................................... 40 Days of Care ............................................................................................................... 44 Results by Hospital Group ......................................................................................... 49 Paediatrics .......................................... , ....................................................................... 55 UNDERSTANDING THE PATTERNS ........................................................................ 60 Acuteness by Portion of Stay ..................................................................................... 60 Acuteness by Day of Admission ................................................................................ 62 Acuteness by Length of Stay ...................................................................................... 63 Comparison with MedisGroups Data ......................................................................... 64 v Acuteness by Patient Characteristics .......................................................................... 66 Socio-Economic Status ........................................................................................ 66 Treaty Indians ..................................................................................................... 67 Distance .from Hospital ....................................................................................... 70 Type ofDiagnosis ............................................................................................... 71 SECOND LOOK .............................................................................................................. 72 Physician Review ....................................................................................................... 73 Results of the Second Look ........................................................................................ 74 D ISCUSSI 0 N ................................................................................................................... 77 The Size of the Problem/Opportunity ........................................................................ 81 Limitations .................................................................................................................. 87 Observation ...............................................................................................................
