Questions and Answers

What was the main problem the physicians at the local university hospital faced in 1967?

They needed help with utilization review due to Medicare program requirements.

Why was there a delay in classifying patients in 1969?

A two-year digression was necessary to develop the technology to analyze patient records.

What system was ultimately developed from the efforts to measure hospital production?

The casemix classification system known as diagnosis related groups (DRGs).

Study Notes

In 1967, physicians at a university hospital sought assistance with utilization review following the Medicare program's implementation in 1965.
Hospitals needed to establish utilization review and quality assurance programs to qualify for Medicare payment, marking the beginning of evaluation efforts in hospital production.
The challenge was determining how to measure productive activity in hospitals, which is distinct from factory production with its clear standards and metrics.
Manufacturing processes are continuously monitored for quality and efficiency, while healthcare required a new approach for assessing performance in clinical settings.
The drive for measurement aimed to enhance processes, resource utilization, efficiency, and effectiveness within hospitals.
In 1969, initial attempts to classify patients revealed the lack of a basic system for interpreting clinical data, necessitating a two-year development phase for the necessary technology.
Advanced statistical and clinical analysis of hundreds of thousands of patient records was developed to identify patterns in care delivery.
A panel of physicians was convened to define essential elements of care processes, leading to the identification of thousands of patient types while emphasizing patient uniqueness.
Focus shifted to recognizing similarities among patient cases to create a structured approach for measuring and evaluating hospital activities.
A key objective was to distinguish standard practices from outliers, utilizing statistical process control to delve into exceptions and uncover their causes.

Casemix Approach vs. Traditional Approach

Casemix approach prioritizes the overall bundle of goods and services provided to patients rather than focusing on individual services.
This method enables the consideration of service utilization effectiveness and production efficiency.

Healthcare Cost Growth in the United States

Healthcare costs in the U.S. increased over 15% annually during the 1970s, significantly outpacing general inflation.
Proportion of gross national product spent on health services rose from 7.4% in 1970 to 10.7% in 1983, exceeding 15% in the 1990s.

Comparative Health Expenditure

U.S. per capita health expenditures are 40% higher than Canada, 60% higher than Sweden, 90% higher than Norway, and 120% higher than Finland and Australia.
There are significant disparities in healthcare expenditures and service rates within the U.S.

Public Health Statistics

Public health statistics do not indicate better population health in the U.S. compared to other Western nations.

Development of Casemix Classification

Efforts to measure and evaluate health care sector output began at Yale University in 1967 but received funding in 1975 from the Social Security Administration.
The aim was to create a payment system for hospitals based on defined products or case types, reflecting distinct processes of care.

Support and Collaboration

Received support from the Bureau of Quality Assurance for the development of casemix classification in quality assurance.
Initial team included experts from Yale’s Department of Public Health and several graduate students, with significant contributions from Ronald E. Mills and Richard F. Averill.
Jean L. Freeman joined the project in 1976, and Professor George Palmer contributed in 1980.
