Quality control for invasive cardiology: Holland
1St. Antonius Hospital, Nieuwegein, The Netherlands.
Insights
Dutch quality control for coronary interventions, including percutaneous transluminal coronary angioplasty (PTCA), shows low mortality rates. Guidelines ensure cardiac surgery and interventions are integrated, with PTCA indications largely appropriate.
Area of Science:
- Cardiology
- Interventional Cardiology
- Public Health Policy
Background:
- No official registry for coronary heart disease treatments exists in the Netherlands.
- Quality control is managed by governmental bodies, the Dutch Society of Cardiology, and health insurers.
- Historical licensing requirements mandated Ministry of Health approval for coronary interventions until 1991.
Purpose of the Study:
- To evaluate the quality control measures and outcomes of coronary interventions in the Netherlands.
- To assess the appropriateness of percutaneous transluminal coronary angioplasty (PTCA) indications.
- To examine the integration of cardiac surgery and interventional cardiology services.
Main Methods:
- Analysis of guidelines from Dutch authorities and professional societies.
- Review of quality survey data from the Dutch Society of Cardiology.
- Examination of health insurer data and the DUCAT-study utilizing RAND criteria.
Main Results:
- PTCA mortality rate is approximately 0.3%, with an infarction rate of 2%.
- Emergency bypass surgery is required in 1.0-1.6% of cases.
- Over 90% of PTCA indications were deemed appropriate based on RAND criteria, with no inappropriate indications found in health insurer data.
Conclusions:
- Current quality control measures and guidelines appear effective in ensuring appropriate and safe coronary interventions.
- Integration of cardiac surgery and interventional cardiology is recommended.
- Governmental efforts to control PTCA center expansion may lead to longer waiting lists.
Abstract:
Although no official registration of indications, treatments and results in patients with coronary heart disease has taken place in Holland, the following authorities and commissions have introduced guidelines for quality control: the Dutch government, the Dutch Society of Cardiology, the Working Group on Interventional Cardiology and the health insurers. Until 1991, the right to perform coronary interventions was tied to a license issued by the Ministry of Health. New recommendations were delineated 5 years ago: at least 500 interventions must be annually performed by 5 interventional cardiologists, i.e. ca. 100 interventions annually per cardiologist. No interventional cardiology may be performed without an in-house cardiac surgery and vice versa. In a survey by the Dutch Society of Cardiology on the quality of the Dutch centers, PTCA-mortality was ca. 0.3%, infarction rate was ca. 2%. An emergency bypass operation was necessary in 1.0 to 1.6% of the cases; the surgical team was on immediate alert for 11% of the patients. Selection of patients without risk was deemed impossible. Despite objections by some members the Dutch Society of Cardiology, it was recommended that cardiac surgery and interventions should not be separated. Data from health insurers showed no inappropriate indications for PTCA. The DUCAT-study, which used the RAND criteria, showed PTCA indications to be correct in more than 90% of the cases. The Dutch government wants to control the expansion of PTCA centers, so it is no wonder that waiting lists are becoming longer.
