Although no official registration of indications, treatments and resul
ts 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 Cardio
logy, the Working Group on Interventional Cardiology and the health in
surers. Until 1991, the right to perform coronary interventions was ti
ed to a license issued by the Ministry of Health. New recommendations
were delineated 5 years ago: at least 500 interventions must be annual
ly performed by 5 interventional cardiologists, i.e. ca. 100 intervent
ions annually per cardiologist. No interventional cardiology may be pe
rformed without an in-house cardiac surgery and vice versa. In a surve
y by the Dutch Society of Cardiology on the quality of the Dutch cente
rs, PTCA-mortality was ca. 0.3%, infarction rate was ca. 2%. An emerge
ncy bypass operation was necessary in 1.0 to 1.6% of the cases; the su
rgical 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 h
ealth insurers showed no inappropriate indications for PTCA. The DUCAT
-study, which used the RAND criteria, showed PTCA indications to be co
rrect in more than 90% of the cases. The Dutch government Rants to con
trol the expansion of PTCA centers, so it is no wonder that waiting li
sts are becoming longer.
