Summary
This study introduces twelve novel indicators for monitoring ambulatory care systems, enhancing health service utilization insights and physician accountability. These indicators are achievable using existing data and privacy-preserving cryptographic methods.
Area of Science:
- Health Services Research
- Public Health Surveillance
- Health Economics
Background:
- Ambulatory care generates vast data, yet lacks synthetic indicators for policy-makers regarding health service utilization and costs.
- Existing public health indicators inadequately support physician accountability.
- Switzerland faces high medical visit frequency, rising care expenditures, and limited public health information despite structured data availability.
Purpose of the Study:
- To develop a universal conceptual framework for ambulatory care surveillance.
- To propose novel, privacy-preserving indicators for health services utilization and cost analysis.
- To enhance physician accountability through objective performance metrics.
Main Methods:
- A universal conceptual framework based on six entities: population, people with poor health, patients, services, resources, and effects.
- Utilization of modern cryptographic techniques to ensure privacy protection.
- Development of twelve key performance indicators derived from routinely available data.
Main Results:
- Twelve indicators proposed for ambulatory care surveillance: morbidity, accessibility, relevancy, adequacy, productivity, efficacy, effectiveness, efficiency, coverage, and financing.
- Indicators are achievable using routinely available data, overcoming conceptual shortcomings.
- The surveillance system's estimated annual cost is under Euro 2 million (Euro 0.3 per capita).
Conclusions:
- The proposed framework and indicators offer a global view of health service utilization and costs in ambulatory care.
- These indicators can be implemented without compromising privacy, using advanced cryptographic methods.
- The system provides valuable data for policy-makers and physicians, improving accountability and resource management within the Swiss healthcare context.
