At the level of first contact, a primary health care centre, informati
on management is an unwieldy task, therefore health information system
s are reported to be inadequate and weak. Microcomputers could improve
information management at this level, but there is little success due
to a lack of specialized application software. In this paper we descr
ibe software developed after a multi-centre systems analysis study, on
an essential data set, to support the delivery of the public health p
rogrammes for family welfare, i.e. maternal health care, family planni
ng and immunization programmes. The modular approach was taken to deve
lop a common application software for information management use at mu
ltiple sites. The software is tested in a laboratory mode by retrospec
tive data entry from sites in Sweden and in India. All the information
could be entered and site-specific reports that were generated are co
mpared. The software provided a common data collection format, an esse
ntial platform for outcomes research.
