ABSTRACT
INTRODUCTION To provide equal access, health care provision
should be distributed across geodemographic space based on need.
In Argentina, the social security, publicly funded health care and
private health care subsectors are responsible for delivering health
services. In the public subsector, which is responsible for providing
primary and secondary care mainly to the uninsured population, supply
of services is not always associated with need. The lack of coordination
between levels and subsectors makes it diffi cult to transform
need into demand.
OBJECTIVE Design a methodology to systematically estimate need,
demand and supply of primary health care services based on secondary
data sources in order to assess potential mismatches in any
geographical area.
METHODS An ecological analysis was conducted based on outpatient
visits in primary care in Bahía Blanca, Buenos Aires Province,
Argentina. A mathematical approach was proposed to systematize
data collection by census tract regarding estimated need (number
of outpatient visits needed, by specialty, according to age- and sexspecifi
c care protocols and the area’s demographics), demand (actual
outpatient visits by specialty in each primary health care center), and
supply (visit capacity or available appointment slots, taking into account
number of personnel hours worked, by specialty).
RESULTS Demand for outpatient visits exceeded need (299,731) by
24% while available visit capacity (993,903) could have covered more
than twice the number demanded (370,881). Analysis of the three
variables grouped by area found that supply correlated more closely
with demand (ρ = 0.90) than with need (ρ = 0.68), while spatial analysis
showed that supply distribution responded to need. Areas with
greater need had a health facility relatively close by, although supply
was often located in areas of lower need, and some areas struggle
with relatively high need and insuffi cient supply.
CONCLUSIONS Results suggest the need for some reconfi guration
of primary health care in the study area. The proposed mechanism for
estimating relationship among supply, demand and need is a useful
tool to support decision-making.
