Background: The decision to prescribe antibiotics and the selection of an appropriate antibiotic are important in the treatment of infectious diseases. As any human decision, it can be influenced by individual attitudes and perceptions. Objectives: To assess the attitudes and perceptions of healthcare providers regarding antibiotic prescribing and the use of laboratory results in infection diagnosis. Methods: A cross sectional survey in five selected Health Service Areas (HSAs) in the Southern Africa country of Lesotho. The questionnaires were self-administered to 67 healthcare providers in public health institutions within the selected HSAs. Data were analyzed using Fisher's exact test or the McNemar Test for dependent proportions. Results: 51 surveys were returned (39 medical doctors, 12 nurses). Respondents typically practiced in urban settings, worked with both inpatients and outpatients, had over 10 years experience, and attended to at least 26 patients per day. We identify several inappropriate practices related to the use of on-site microbiology laboratories. For example, only 17% always send a sample for microscopic identification prior to prescribing antibiotics and only 32% always send a sample for culture sensitivity tests. Delays in obtaining laboratory results and high patient workloads were cited as reasons for under-utilization of laboratory facilities. Nearly all respondents recognize the need for guidelines and further training in antibiotic prescribing. Conclusions: Healthcare providers demonstrated attitudes and perceptions in antibiotic prescribing or use of laboratory derived information in infection diagnosis that could have negative impacts on antibiotic prescribing.

The study primarily aimed at assessing the appropriateness of antibiotic prescriptions in a section of public health institutions in Lesotho using an assessment tool formulated from principles of antibiotic prescribing. Relevant data on procedures of infection diagnosis and prescribed antibiotics were collected from both inpatient and outpatient case reports for a one-month period in five public hospitals in Lesotho. These were analyzed for the appropriateness of the prescribed antibiotics. Prescription appropriateness assessment was based on conformities of prescribed antibiotics to criteria developed from pertinent principles of antibiotic prescribing. Assessed prescriptions, 307 inpatient and 865 outpatient prescriptions in total, were classified into categories of appropriateness based on extents to which they satisfied conditions defined by combinations of criteria in the assessment tool. Antibiotic prescriptions from inpatient and outpatient departments of study site hospitals were categorized into groups of different degrees of appropriateness. A total of 32.2% inpatient prescriptions and 78.4% outpatient prescriptions assessed were appropriately written for the empiric treatment of infections for which bacterial pathogens were considered absolute or possible etiologies. The use of prescription assessment tools based on principles of antibiotic prescribing is a feasible option of assessing the appropriateness of antibiotic prescriptions, particularly in low-income countries where expert panels cannot be formed.

This two day meeting brought together drug utilisation researchers from across Africa. The purpose was to share current drug utilisation (DU) research findings to further DU research across Africa including the development of a medicines utilisation research group. This led to the formation of the MURIA (Medicine Utilisation Research in Africa) Group, with a tentative vision and mission as well as the first planned research methodology training course and a symposium in Botswana later in the year. Future research projects were also planned including studies on drug utilisation of ARVs in Botswana and across Africa as well as ways to enhance the appropriate use of antibiotics and increase generic utilisation.

The therapeutic impact of inappropriate prescribing of antibiotics is debatable, particularly in situations where infections are treated empirically with multiply prescribed antibiotics. Prescribers may remain under the illusion that such prescriptions are appropriate on the basis of any observed positive treatment outcomes, even though an antibiotic prescribed in such combination therapy may actually be infective against infecting pathogens. This, inevitably, promotes inappropriate antibiotic prescribing. Prescribers may be motivated to make more conscious attempts to prescribe antibiotics appropriately if it is proven that judicious prescribing of antibiotics has positive impacts on treatment outcomes. The objective of this study was to determine the impact of appropriate prescribing of antibiotics on treatment outcomes, days of patient hospitalization and costs related to antibiotic treatment. Observational data on antibiotic treatment were collected for a one-month period from case notes of all inpatients (n=307) and outpatients (n=865) at five government and mission hospitals in Lesotho. Prescriptions were classified into categories of appropriateness based on extents to which antibiotics were prescribed according to principles. Treatment success rates, mean days of hospitalization and costs of antibiotic treatments of inpatients treated with specified prescription categories were determined. Appropriate prescribing of antibiotics for inpatients had positive impacts on treatment outcomes, patients’ days of hospitalization for infections and costs of antibiotic treatments. In outpatient settings, appropriate prescribing of antibiotics failed to show any significant impact on costs of antibiotics. Appropriate prescribing of antibiotics had a positive impact on patients’ recovery and costs of antibiotic treatments in inpatient settings.
