Aspects of drug usage in a private primary health care setting : a pharmacoeconomic approach / Lerato Clara Dedwaba

In South Africa, significant changes in health care have taken place since the first democratic
elections in 1994. The change had lead to a position of integrated service delivery with specific
reference to primary health care. Increasingly in developing countries, the private sector impacts
significantly on the rights to education and the highest attainable standard of health.
Inappropriate prescribing e.g. prescribing a drug without an acceptable indication, specifying an
incorrect dosage, schedule or duration of treatment, duplicating therapeutic agents and
prescribing drugs without adequate regard to potential interactions, can cause adverse
outcomes, deplete health care resources, compromise the quality of care and possible increase
in health costs. One approach monitoring prescribing practices is drug utilisation review.
The general objective of this study was to review and interpret aspects of drug usage patterns in
a private primary health care setting, with special reference to the top ten diagnoses made and
the top twenty medicine items prescribed as well as the associated costs. A quantitative,
retrospective drug utilisation review as well as certain aspects of managed and primary health
care, pharmacoeconomics, pharmacoepidemiology, medicine formularies and standard
treatment guidelines were reviewed in the literature as a base for the study.
The results of the empirical study showed that 83648 patients consulted at the nine medicentres
during the study period (1 January to 31 December 2001). A total number of 132591 patient
visits (consultations) were made, 140723 medical conditions (diagnoses) performed and
516177 medicine items prescribed during the study period.
Analysis of medicine usage patterns and associated costs of the top ten diagnoses made and
top twenty medicine items prescribed in the study population, revealed the following: The top ten diagnoses determined accounted for 29.07% of the total number of
diagnoses made,
. a total medicine treatment cost accounting for 32.11% in the study population,
. the top twenty medicine items determined accounted for 56.23% of the total medicine
items prescribed and
. a total medicine treatment cost accounting for 28.63% in the study population.
The highest prevalence of diagnoses made and medicine items prescribed was found in age
groups 4 and 5 (Le. patients between the ages of 19 to 40 years) and was also found to be
more prevalent in the female than in the male population.
In completion of the research, recommendations to review the medicentres medicine treatment
protocols and on provision of primary health care education were made. Reference to the
investigation of environmental factors is also made. / Thesis (M.Pharm.)--North-West University, Potchefstroom Campus, 2004.
