Evaluating drug use patterns among paediatric outpatients in Burundi.

Background: Rational prescribing is key to optimising therapeutic outcomes and avoiding risks associated with irrational use of medicines. Using WHO drug use indicators, this study evaluated drug use patterns among paediatric outpatient encounters at Primary Healthcare Centers (PHCs) in Bujumbura Mairie, Republic of Burundi. Methods: Descriptive cross-sectional research assessed paediatric medicine use in 20 PHCs. From 8 February to 7 April 2023, 800 randomly selected paediatric encounters' 2022-year data were retrospectively collected. Data for specific facility indicators were prospectively collected. SPSS 23 was used to analyse data. Results: 800 outpatient child encounters were analysed, 48.4% female and 51.6% male. The mean number of medicines per encounter was 2.4(±0.99). The injection rate was 9.9%. Overall, 78.8% of generics and 85.2% of essential medicines were prescribed. Results show drug prescribing differences between private and government PHCs (p < 0.001). All PHCs studied had no standard treatment guidelines (STGs), while 50% had an essential medicine list (EML) and 85% of key medicines were available. Conclusion: Poor prescribing practices were found indicating the need for interventions to promote good drug use practices. A large study at a national scale is required to provide a more comprehensive understanding of the overall drug use practices.

Assessment of vaccine management performance in health facilities of Mwanza Region, Tanzania: a cross-sectional study.

BACKGROUND: Effective Vaccine Management (EVM) initiative provides the platform needed to monitor and assess the vaccine supply chain system to identify strengths and weaknesses of the system at all levels and enhance the development of continuous improvement plan to strengthen the system. This study was conducted to determine the vaccine management performance in Health Facilities of Mwanza Region, Tanzania. METHODS: This was a descriptive cross-sectional study that was carried out in 102 health facilities providing immunization services from eights districts of Mwanza Region in Tanzania. The World Health Organization (WHO) effective vaccine management assessment tools were used to collected data. Both quantitative and qualitative (through key informant interviews) approaches were used. The quantitative data were analysed using the existing WHO criteria for analysing effective vaccine management assessment data, while deductive thematic analysis was used for the qualitative data. RESULTS: The finding shows that the overall score for vaccine management performance was 53% which is below the WHO acceptable minimum score of 80%. None of the health facilities had reached the benchmark but only 67% had an average performance (> = 50-< 80%). The highest health facility score was 76% and the lowest being 27%. Among the categories assessed, the highest score was on information technology with 72%, while the lowest was on standard operating procedures with a score of 43%. The major challenges which contributed to low performance were lack of training, low knowledge about vaccine management practices, unavailability of standard operating procedures (SOPs), and limited financial resources to support operations for vaccine management practices. Skills gap, incomplete stock records and management, as well as low availability of SOPs were the key challenges reported that affected vaccine management practices. CONCLUSIONS: Effective vaccine management performance was low across all districts under the study. Increasing personnel capacity and ensuring availability of resources to support operations were reported as key interventions in improving vaccine management practices. Hence, effectively working on continuous improvement plan with key highlighted actions is highly recommended to all actors from national level to sub-national level managers and healthcare workers as frontline vaccine handlers.

Evaluation of vaccine storage and distribution practices in rural healthcare facilities in Kenya.

BACKGROUND: Vaccines require cold chain storage conditions, and good distribution practices throughout the supply chain to maintain their quality and potency. However, in the last mile of the vaccines supply chain, these requirements may not be guaranteed resulting in reduced effectiveness which could lead to an upsurge in vaccine preventable morbidity and mortality. The aim of this research was to evaluate vaccine storage and distribution practices in the last mile of vaccine supply chain in Turkana County. METHODS: A descriptive cross-sectional study was conducted from January 2022 to February 2022 across seven sub-counties in Turkana County, Kenya, to assess vaccine storage and distribution practices. The study sample size was 128 county health professionals across 4 hospitals, 9 health centers, and 115 dispensaries. The respondents were selected using simple random sampling within the facilities strata. Data were collected using a structured questionnaire, adapted, and adopted from a standardized WHO questionnaire on effective vaccines management and administered to one healthcare personnel working in the immunization supply chain per facility. Data were analyzed using excel and presented as percentages in table forms. RESULTS: A total of 122 health care workers participated in the study. Most respondents (89%, n = 109) had utilized a vaccine forecasting sheet, but only 81% did have an established maximum-minimum level inventory control system. Many of the respondents had sufficient knowledge of ice pack conditioning although 72% had adequate vaccine carriers and ice packs. Only 67% of respondents had a complete set of twice-daily manual temperature records at the facility. Most refrigerators complied with the WHO specifications but only 80% of them had functional fridge-tags. The number of facilities that had a routine maintenance plan was below average while only 65% had an adequate contingency plan. CONCLUSION: Rural health facilities have suboptimal supply of vaccine carriers and icepacks for effective storage and distribution of vaccines. In addition, some vaccine fridges lack functional fridge-tags for proper temperature monitoring. Routine maintenance and contingency plans remain a challenge to ensure optimal service delivery.

Conglomeratin: a new antibacterial flavonol derivative from Macaranga conglomerata Brenan (Euphorbiaceae).

A new prenylated kaempferol, conglomeratin (1), alongside 7 known compounds including flavonoids (2 and 3), ellagic acid derivatives (4 and 5), triterpenoids (6 and 7), and a coumarin (8) were isolated from the leaves (1 - 5) and stem bark (6 - 8) of Macaranga conglomerata. Their structures were elucidated using spectroscopic and spectrometric techniques. The antibacterial assay was performed using disc diffusion method against Gram-positive and Gram-negative microorganisms. Compound 1 was significantly active against Pseudomonas aeruginosa ATCC 27853 (MIC = 7.8 µg/mL) and moderately active towards Staphylococcus aureus ATCC 25923, Escherichia coli ATCC 25922 and Klebsiella pneumoniae ATCC 31488 (MIC = 62.5 µg/mL). Compound 2 showed potency against P. aeruginosa ATCC 27853 (MIC = 1.0 µg/mL) while 4 and 7 were selective towards K. pneumoniae ATCC 31488 (MIC = 7.8 and 1.0 µg/mL, respectively). These findings suggest that prenylation of flavonoids may contribute to improving their broad-spectrum antimicrobial activities.

Factors that affect vaccines availability in public health facilities in Nairobi City County: a cross-sectional study.

INTRODUCTION: over 1.5 million children die from vaccine-preventable diseases yearly. To avert these deaths and improve their livelihood, vaccine availability is important. The study assessed the availability of the vaccine, injection accessories and the associated factors in public health facilities in Nairobi City County and provided valuable data to contribute to improving healthcare infrastructure, stock management and vaccine distribution. METHODS: a descriptive cross-sectional study was conducted in 68 randomly selected public health facilities at Nairobi City County in Kenya. Data was collected using a researcher-administered structured questionnaire and more information abstracted from the Vaccines management tools. The analysis was carried out using STATA version 14. RESULTS: most facilities had experienced vaccines and accessories stock out at the time of the study and in the preceding twelve months. The most affected vaccines were tetanus (88%), measles-rubella (81%) and oral polio (79%). The causes of stockouts were rationing (82%), unavailability at the depot (93%), lack of transport (55%) and poor forecasting (50%). The majority (91%) of the facilities used the public transport system and only 1% had reliable government utility vehicles for delivery of vaccines and other logistics. Those near the vaccine depots preferred walking. CONCLUSION: the public health facilities in Nairobi City County experienced frequent stockouts of vaccines and accessories thereby exposing the residents to vaccine-preventable diseases.
