A study was carried out to assess the quality of case management of ma
laria, malnutrition, diarrhoea and acute respiratory tract infections
in children in rural primary health services in Papua New Guinea. In p
articular, the study focused on the knowledge and skills of different
categories of rural health workers (HW) in history taking, examination
, diagnosis, treatment and patient education. Quality criteria were de
fined and health centre (HCW) and aidpost workers' (APWs) knowledge an
d practices were assessed, Primary health workers' (PHW) knowledge of
case management was weak, but in all cases better than their actual pr
actice. History taking and examination practices were rudimentary. HWs
tended not to make or record diagnoses. Treatment knowledge was often
incorrect, with inappropriate or insufficient drugs prescribed, being
worst at aidpost level. These findings raise serious questions about
the effectiveness of providing health services through small, isolated
health units. Far greater attention must now be directed to focus on
the institutionalization of problem-based training, continuous support
ive supervision and maintenance of clinical skills and provision of es
sential drugs, supplies and equipment to ensure that rural health work
ers (RHW) can provide sound care.
