Process quality is the commonly used operational definition of health
care quality. Its key components are technical and inter-personal skil
ls, but most assessments undertaken in developing countries focus only
on technical skills. This study from Tanzania used explicit observati
on checklists to review the process of providing antenatal, curative a
nd nursing care in primary health units, assessing both technical and
inter-personal skills. The study findings emphasize the weaknesses in
available care, particularly in the attitudes of health staff but also
in aspects of technical care. Differences in performance between heal
th units appear to be influenced by factors such as workloads, structu
re and staff allocations. Differences between cadres were also identif
ied and may underlie some of the inter-unit differences. The policy ac
tions required to address the problems must reflect the diversity of t
he underlying influences, seeking to raise both technical and inter-pe
rsonal quality, as the two are mutually reinforcing.
