Medical audit based on computer-stored patient records exemplified with an audit of hypertension care
1Department of Medical Informatics, Linköping University, Sundbyberg, Sweden.
Insights
This study audited hypertension care using computer records, finding initial deficiencies in patient history and risk factor analysis. A follow-up audit showed improvements after implementing a care protocol, highlighting the value of electronic health records for medical audits.
Area of Science:
- Medical Informatics
- Public Health
- Cardiology
Background:
- Hypertension management requires regular auditing to ensure optimal patient care.
- Computer-based patient records (CPPRs) offer a potential tool for efficient medical record review.
- Assessing the quality of hypertension care is crucial for improving patient outcomes.
Purpose of the Study:
- To audit the quality of hypertension care at a Swedish health center.
- To evaluate the effectiveness of computer-based patient records and query languages in medical audits.
- To compare hypertension care practices between 1989 and 1990.
Main Methods:
- A retrospective database study was conducted.
- Computer-based patient records were utilized as the data source.
- A query language was employed to analyze patient data for hypertension care compliance.
Main Results:
- The audit reviewed 585 records in 1989 and 574 in 1990 using 30 database queries.
- Initial audit revealed deficiencies in patient history taking and risk factor analysis for hypertension.
- Subsequent audit showed minor improvements in recording and a higher rate of well-treated hypertensive patients after protocol implementation.
Conclusions:
- Computer-based patient records can facilitate medical record reviews for audit purposes.
- Medical audits highlight the discrepancy between ideal care standards and clinical practice in hypertension management.
- Implementing care protocols can lead to measurable improvements in hypertension care quality.
Objective:
To audit hypertension care at a health centre using computer-based patient records as the source of information and a query language as the analysis tool.
Design:
Retrospective database study comparing hypertension care in 1989 with hypertension care in 1990.
Setting:
One health centre in Sweden with six general practitioners and two doctors on vocational training.
Participants:
All patients with hypertension in 1989 and 1990.
Main Outcome Measure:
The percentage of records that complied with the criteria in the hypertension care protocol.
Results:
585 records in 1989 and 574 records in 1990 were reviewed automatically by a series of 30 database queries. The computer time needed for the review was eight hours. The first audit showed deficiencies in the management of hypertension, in particular concerning patient history taking and risk factor analysis. The second audit, after the introduction of the hypertension care protocol, showed some minor improvements in the recording and also an increased rate of well treated hypertensive patients.
Conclusion:
Computer-based patient records may facilitate the review of medical records that is needed in medical audit. The audit demonstrates the gap between optimal care and clinical reality.
