Working more productively: tools for administrative data.

OBJECTIVE: This paper describes a web-based resource (http://www.umanitoba.ca/centres/mchp/concept/) that contains a series of tools for working with administrative data. This work in knowledge management represents an effort to document, find, and transfer concepts and techniques, both within the local research group and to a more broadly defined user community. Concepts and associated computer programs are made as "modular" as possible to facilitate easy transfer from one project to another. STUDY SETTING/DATA SOURCES: Tools to work with a registry, longitudinal administrative data, and special files (survey and clinical) from the Province of Manitoba, Canada in the 1990-2003 period. DATA COLLECTION: Literature review and analyses of web site utilization were used to generate the findings. PRINCIPAL FINDINGS: The Internet-based Concept Dictionary and SAS macros developed in Manitoba are being used in a growing number of research centers. Nearly 32,000 hits from more than 10,200 hosts in a recent month demonstrate broad interest in the Concept Dictionary. CONCLUSIONS: The tools, taken together, make up a knowledge repository and research production system that aid local work and have great potential internationally. Modular software provides considerable efficiency. The merging of documentation and researcher-to-researcher dissemination keeps costs manageable.

Who are the high hospital users? A Canadian case study.

OBJECTIVES: Researchers have taken two different approaches to understanding high use of hospital services, one focusing on the large proportion of services used by a small minority and a second focusing on the poor health status and high hospital use of the poor. This work attempts to bridge these two widely researched approaches to understanding health care use. METHODS: Administrative data from Winnipeg, Manitoba covering all hospitalizations in 1995 were combined with public use Census measures of socio-economic status (neighbourhood household income). High users were defined as the 1% of the population who spent the most days in hospital in 1995 (n = 6487 hospital users out of population of 648715 including non-users). RESULTS: One per cent of the Winnipeg population consumed 69% of the hospital days in 1995. Thirty-one per cent of the highest users were among the 20% of residents of neighbourhoods with the lowest household incomes, and 10% of the highest users were among the 20% from neighbourhoods with the highest household incomes. However, on most other dimensions, including gender, age, average days in hospital, average admissions, percentage who died in hospital and diagnostic reasons for being hospitalized, the similarities between high users, regardless of their socio-economic group, were striking. CONCLUSIONS: The lower the socio-economic status, the more likely an individual is to make high demands on hospitals. However, patterns of use as well as the diseases and accidents that produce high use among residents of low income neighbourhoods are not much different from those that produce high use among residents of high income neighbourhoods.

Patients hospitalized for medical conditions in Winnipeg, Canada: appropriateness and level of care.

A medical record review of patients hospitalized for medical conditions in Winnipeg, Canada during 1998/99 was completed using InterQual utilization review instruments. On admission, 95% of patients required the services provided in an acute care facility. Fifty-eight percent of days in hospital following the day of admission required an acute care setting, and 42% required an alternate level of care. Our results suggest there is room for treating more acute patients within the existing system.

Community resources and determinants of the future health of Manitobans.

BACKGROUND: Life history studies in health show that some of the key determinants of health inequalities lie in biological and social experiences at the earliest times of life. The objectives of this research were to describe the regional distribution of childhood determinants of adult health, such as school achievement, and the environments which contribute to their development. METHODS: Using Manitoba data from the National Population Health Survey, the National Longitudinal Survey on Children and Youth, the Department of Education, Training and Youth, the Department of Family Services and Housing, the Library Association website and the Agriculture and Food website, the regional distribution of Grade 3 standards test scores and neighbourhood resources such as child care services, libraries, sports participation and food costs were determined for 12 Regional Health Authorities and 12 Winnipeg Community Areas, ranked by a measure of population healthiness, the premature mortality rate. Findings were also reported by income level and larger geographic regions. RESULTS: Children living in neighbourhoods with less healthy populations were more likely to have poorer school performance, as indicated by Grade 3 math standards test scores. They were-also more likely to change schools, less likely to participate in sports, and had decreased access to affordable food and licenced day care. They had similar access to library books as children living in more healthy neighbourhoods, although book lending rates were not measured. CONCLUSION: We documented regional variation in the availability of resources to support healthy childhood development.
