Abstract  Antibiotics are essential with inappropriate use leading to antimicrobial resistance (AMR). Currently, little is known about antibiotic use among hospitals in Kenya, which is essential to tackle as part of the recent national action plan addressing rising AMR rates. Consequently, the objective was to overcome this gap in a leading referral hospital in Kenya. The findings will subsequently be used to develop quality improvement programs for this and other hospitals in Kenya. Methods: This was a point prevalence survey. Data on antibiotic use were abstracted from patient medical records by a pharmacy team. Findings: The prevalence of antibiotic prescribing was 54.7%, highest in the intensive care unit and isolation wards. Most antibiotics were for treatment (75.4%) rather than prophylaxis (29.0%). The majority of patients on surgical prophylaxis were on prolonged duration (>1 day), with only 9.6% on a single dose as per current guidelines. Penicillins (46.9%) followed by cephalosporins (44.7%) were the most prescribed antibiotic classes. The indication for antibiotic use was documented in only 37.3% of encounters. Generic prescribing was 62.5% and empiric prescribing was seen in 82.6% of encounters. Guideline compliance was 45.8%. Conclusion: Several areas for improvement were identified including addressing prolonged duration for prophylaxis, extensive prescribing of broad-spectrum antibiotics, high rates of empiric prescribing, and lack of documenting the indication for antimicrobials. Initiatives are ongoing to address this with pharmacists playing a key role.

Abstract The objective of this study was to evaluate the extent of self-medication of antibiotics and dispensing practices in Kenya. Methods: A cross-sectional study was carried out at three selected pharmacies in Nairobi (Kenya), between January and March 2017, targeting principally antibiotic prescriptions for systemic use issued and dispensed as well as antibiotics sold over-the-counter without a prescription. The quality of antibiotics prescribed and dispensed was assessed against key WHO and other criteria. Benchmarking was used to assess the quality of antibiotics prescribed as there are no predetermined levels, just guidance and the rationale. Key indicators included: utilization of penicillins, percentage utilization of third-and fourth-generation of cephalosporins versus first and second generation, utilization of macrolides including lincosamides and utilization of quinolones as a percent of total systemic antibiotic use. Findings: There was a low level of dispensing of antibiotics without a prescription with over 90% (94.1%) of antibiotics dispensed with a valid prescription. The most common antibiotics dispensed were the penicillins at just over 50% of all antibiotics, the cephalosporins at over 12% (12.6%) and the fluoroquinolones at just under 12% (11.7%). There were concerns with high use of third and fourth generation cephalosporins versus first- and second-generation as well as co-amoxiclav versus other penicillins. Conclusion: Low levels of self-medication of antibiotics and high adherence to quality standards for dispensing are encouraging and provide direction to other countries. Educational initiatives are needed though to address high levels of co-amoxiclav prescribing.
