L. Malcolm, TRENDS IN PRIMARY MEDICAL-CARE RELATED SERVICES AND EXPENDITURE IN NEW-ZEALAND 1983-93, New Zealand medical journal, 106(967), 1993, pp. 470-474
Aims. To analyse recent trends in primary medical care (PMC) related e
xpenditure, general medical services (GMS), pharmaceuticals, laborator
y, Accident Compensation Corporation (ACC) and other categories, as a
basis for general practitioners, other primary health care providers a
nd regional health authorities becoming better positioned to make more
effective decisions about the use of this expenditure. Methods. Data
from the Department of Health, Accident Compensation Corporation and o
ther sources of this expenditure over the period 1983-93 were obtained
and analysed. Results. Primary medical care related expenditure betwe
en 1982-3 and 1990-1 increased annually at an inflation adjusted rate
of 6.1% to a total of $1006.2M. In 1991-2 there was a slight inflation
adjusted decrease in overall primary medical care related expenditure
of 0.5% although maternity benefits increased by 20.7%. An overall in
crease of 2.7% occurred in 1992-3 with a 10.1% increase in laboratory
benefits and 16.4% in maternity benefits. Price, volume, mix and other
factors were analysed to explain these increases. The overriding dete
rminants of the cost increases are the volume of primary medical care
related services such as pharmaceuticals, laboratory and maternity ser
vices and the mix effect ie, more expensive drugs, tests, etc. Conclus
ion. Alternative strategies for control of primary medical care relate
d service utilisation costs are discussed. It is suggested that the mo
st effective strategy is some form of general practitioner or communit
y based budget holding within which general practitioners and/or commu
nities are empowered to make decisions about their priorities in achie
ving the best possible quality and quantity of primary health care.
