Prescribing habits in church-owned primary health care facilities in Dar Es Salaam and other Tanzanian coast regions.
OBJECTIVE
To assess prescribing practice of Primary Health Care (PHC) workers in church owned health care facilities using WHO drug use indicators.


METHODS
A cross-sectional study in which twenty primary health care facilities were randomly selected. Prescribing indicators were obtained by analysing outpatient records retrospectively for the past 14 months between January 1997 and February 1998. This period was chosen because of compete records of outpatient attendances. Patient care and facility indicators were recorded prospectively during the study period.


METHODS
The study was conducted in the Coast and Dar es Salaam regions of Tanzania. Six districts were randomly selected from both regions. The selected districts included Ilala, Temeke and Kinondoni in Dar es Salaam, Kibiti, Bagamoyo and Kisarawe in Coast region.


METHODS
Twenty primary health care facilities were randomly selected from the chosen districts. Patient registers were collected and patients' characteristics including age, sex, diagnosis, and drugs prescribed for the period January 1997 to February 1998 were recorded on data collection forms. Patient care indicators were measured by recording consultation time, dispensing time, per cent of drugs actually dispensed and adequately labelled whereas patients' knowledge of correct drug dosage was obtained using exit interviews. Verification of facility indicators was done by direct observation.


RESULTS
The average number of drugs per prescription was 2.3 (range 1.8-2.8). Generic prescribing prevailed with a mean of 75.5% of all drugs. Antibiotic and injection encounters per prescription was 35.4 and 19%, respectively. Most drugs were prescribed according to the essential drug list of Tanzania (NEDLIT). Patient's average consultation time was 3.6 minutes whereas average dispensing time was 39.9 seconds. On average, 87% of all drugs dispensed were adequately labelled and patients' knowledge of correct dose was adequate. All facilities possessed drugs for treating important illnesses, all had reference educational materials.


CONCLUSIONS
The study shows that there is an overuse of injections 19% +/- 1.7 (range 0.73%) compared to the recommended figure of 15%. The use of antibiotics appears appropriate when compared with the morbidity patterns in the study areas. A focus group discussion with prescribers in these facilities to address the question of overuse of injections is needed in order to plan an appropriate intervention.
