Organizing Principles of POPULIS

• 1. It describes
• - supply
• - access to care
• - intensity of use
• - differential use across areas
• 2. It juxtaposes indicators of -
  socioeconomic risk
• - use
• - health

5

• 3. It assesses contributions to costs per capita
  of
• - differential access
• - dollars per service (visit, day of care)
• 4. It is relevant to system managers
• 5. It sums use across sectors
• 6. It creates regional profiles

Where to find Population-Based Administration Data

• 1. Several Canadian provinces
• 2. Rochester (Minnesota) Epidemiology Project
• 3. Oxford Record Linkage Study
• 4. Scottish Record Linkage System
• 5. Western Australia Health Services Research
  Linked Database Project

Organizing and Accessing Information

• Since many researchers use the same
• data to answer different research
• questions, various methods of analysis
• may be applied to them.
• Problem How can an organization store
• its working knowledge for easy access
• and to guard against conflicting
• interpretations of the same data?

Other On-line Dictionaries

• Glossary - gateway to Concept Dictionary
• Research Definitions - codes for surgical
  procedures, test and diagnoses
• Data Dictionaries - list and describe variables
  and file structure for databases.
• ?Meta-Index - organizes concepts and definitions
  according to the Medical Sub-Heading (MeSH) system

Developing Indicators Steps

• 1. Create meaningful geographical areas
• 2. Obtain denominator data for each area
• 3. Develop indicators of socioeconomic risk for
  each area
• 4. Develop indicators of health status
• 5. Describe utilization of health care by
  residents

13
Community Indicators

• 1. Demographic profile
• 2. Low weight births
• 3. Health care system sensitive
  indicators

14

• 4. Mortality indicators population
  cause-specific
• 5. Indicators based on rates of individuals
  hospitalized
• 6. Indicators based on rates of physician contact

15
FLAGSHIP INDICATOR

• Premature Mortality Rate
• (Rate of death of persons 0-74)
• ? Best overall indicator of health status
  incorporating need for health care
• ? Well correlated with morbidity measures

16
Questions Recently Addressed Using POPULIS

• 1. Have bed closures adversely affected
• A. Manitobans access to care?
• B. The quality of care delivered?
• C. The health of the population?

• 2. When does seasonal hospital overcrowding
  occur? Why does it occur? Is it due to bed
  shortages?

4. Are there different ways of delivering
preventive or screening programs that are
successful in reaching all groups in the
population?
27
Research has shown that poor people tend to
have more health problems than the wealthy and
that they are less likely to make use of
preventive or screening programs, despite
universal free health care in Canada. Roos,
Traverse and Turner (1999)12 considered how such
services could successfully reach all groups in
the population. They used data from the research
registry and from files maintained by two
established provincial programs to examine
childhood immunization, screening mammography and
cervical cancer screening.

Conclusions

• As we rethink health in the context of a
• population health framework, there is a need for
• an information system designed to provide
• evidence to support policy and health services
• decisions in managing the health care system.
• There is an equal need to communicate research
• findings with policymakers, providers, and the
• public.

  Health, Province of Manitoba13
