Antibiotic use and resistance patterns at Rumphi District Hospital in Malawi: a cross-sectional study.

BACKGROUND: Overuse of antibiotics is a key driver of antimicrobial resistance (AMR) world-wide. Malawi continues to report rising cases of AMR among both in-patients and out-patients. We investigated antibiotic use and resistance patterns among patients with suspected first line antibiotic treatment failure at Rumphi District Hospital, Malawi. METHODS: We used a cross-sectional study design in which records of patients data on culture and antimicrobial sensitivity tests were extracted, alongside treatment history from 2019 to March, 2023, retrospectively. We also included findings for point prevalence survey (PPS) conducted within four hospital wards in June, 2022 by a well-trained multi-disciplinary team from within the hospital. The data was analyzed for antibiotic use, characterization of pathogens and their susceptibility patterns using Microsoft excel and STATA-14 software. RESULTS: A total of 85 patients' data records were reviewed on antibiotics resistance pattern in which 54 (63.5%) were females. Patient antibiotic history captured indicated Metronidazole (23%), Gentamycin (20%) and Doxycycline (23%) as the most frequently used antibiotics among clients referred for microbiological investigations. Among locally available antibiotics with over 50% sensitivity were Chloramphenicol (61%), ciprofloxacin (55%), and ceftriaxone (54%). Penicillins were among antibiotics with highest resistance: ampicillin (100%), amoxyclav (90%), Piperacilin-tazobactam (63%). The majority of patients came from STI clinic and presented with genital discharges 44% (n = 39). Over 80% of the isolated N. gonorrhoeae exhibited a reduced susceptibility to gentamycin. Prevalence of Methicillin resistant staphylococcus Aureus (MRSA) was 46% and were mostly isolated from wound pus. Among 80 data records of the patients reviewed during PPS, Ceftriaxone (54.3%) and Metronidazole (23.3%) emerged as the most frequently used antibiotics in the wards which were prescribed empirically without a microbiological indication. CONCLUSION: In this study setting, we observed high use of watch antibiotics along with problem of multi-drug resistant infections in patients experiencing clinical failure in a variety of clinical syndromes. The findings underline the need to revamp diagnostic microbiology to increase the uptake of antimicrobial susceptibility testing to guide specific prescriptions of broad-spectrum antibiotics in the watch list.

Availability, pricing, and affordability of essential medicines for pediatric population in Malawi.

Objective: Lack of access to essential medicines negatively impacts on the quality of healthcare delivery and increases morbidity and mortality, especially to the vulnerable pediatric population. We assessed the availability, pricing, and affordability of pediatric formulations in Malawi. Methodology: The study was conducted in 76 health facilities (public, faith-based and private pharmacies, and clinics) from the northern and southern regions of Malawi from March to May 2023. We adapted the WHO/HAI method for the assessment of both availability and pricing of medicines. Data on availability were collected from stock card records using a WHO/HAI template and medicine prices were provided by the pharmacy personnel who were managing the facilities. Availability of medicines was calculated as the percentage of facilities which had a stock of the respective medicine at the time of data collection while medicine prices was assessed by calculating the median prices of each medicine. To assess the affordability of the medicines, we calculated the number of days it takes for a person who is receiving the government-set minimum wage to work to pay for a treatment course of common indications. The study was approved by the KUHES ethics committee under the numbers U.12/22/3900 and U.12/22/3903. Results and conclusion: The overall availability of pediatric medicines was 38.1% for public health facilities, 53.7% for private retail pharmacies and drug stores, 49.5% for private clinics and 48.3% for Christian Health Association of Malawi (CHAM) facilities. We found the illegal availability of prescription-only medicines of up to 54% in medicine stores. Medicine median prices were higher in the private clinics followed by retail pharmacies and drugs stores. CHAM had the lowest median prices for medicines of all the sectors. More than 50% of medicines were found to be affordable as less than a day's wage was required to purchase the treatment. We found poor availability of pediatric formulation among public, CHAM, and private sectors in Malawi. This may affect the quality of care among pediatric patients and therefore contribute to morbidity and mortality in Malawi. The supply of medicines and health commodities needs to consider needs of special populations such as children to achieve universal health coverage.

Effect of antibiotic medicines availability on adherence to standard treatment guidelines among hospitalized adult patients in southern Malawi.

BACKGROUND: Antibiotic resistance is a global public health problem. High and inappropriate use of antibiotic therapy exacerbate the risk of antibiotic resistance. We assessed the effect of availability of antibiotic medicines on adherence to standard treatment guidelines among hospitalized adult patients in Southern Malawi. METHODS: A cross-sectional study was done to assess the availability of 16 antibiotics among the first-line recommended treatments for common bacterial infections in Malawi. Data for up to six-month duration was extracted from stock card records in Machinga and Nsanje District Hospitals and Zomba Central Hospital. This was complemented by a retrospective review of 322 patient management files from medical wards to assess adherence to the Malawi Standard Treatment Guidelines (MSTG). Investigators abstracted data such as patient demographics, diagnoses, and prescribed therapy using a data collection form that resulted in analyzing 304 patient files. Data was entered into Microsoft excel and analyzed using STATA 14.1. Point availability, stock-out duration and adherence to treatment guidelines were presented in terms of frequencies and percentages. Chi-square test or Fisher's exact test was applied to assess the association between variables and adherence to treatment guidelines. RESULTS: Point availability of antibiotics was 81.5%, 87.7%, and 42.8% for Zomba Central, Machinga and Nsanje District Hospitals respectively. Over a period of six months, 12.5% of antibiotic medicines were stocked out for at least one day at Zomba (Median stock out days = 0, (IQR 0-0 days), while 64.3% were stocked out at Machinga (Median stock out days = 21, IQR 0-31 days) and 85.7% were stocked out at Nsanje District Hospital (Median stock out days = 66.5, IQR 18-113 days). Overall, adherence to MSTG was 79.6%, (95% CI, 73.3-84.9%). By facilities, adherence to guidelines at Zomba Central Hospital was 95.9% (95% CI, 89.7-98.9%) while at Nsanje and Machinga District Hospitals was 73.2% (95% CI, 59.7-84.2%) and 54.2% (95% CI, 39.2-68.6%) respectively. Adherence to treatment guidelines was associated with health facility, presence of laboratory test results, antibiotic spectrum, and WHO-AWaRe category of the medicine, p<0.005. Adherence was lower for antibiotics that were stocked out than antibiotics that were not stocked out during the study period (63.8%, 95% CI 48.5-77.3% vs 84.4%, 95% CI 77.7-89.8%), p< 0.002. CONCLUSION: We found unstable availability of antibiotic medicines in hospitals which might contribute to the sub-optimal adherence to standard treatment guidelines. This is a setback to efforts aimed at curbing antibiotic resistance in Malawi.

Temperature variations in pharmaceutical storage facilities and knowledge, attitudes, and practices of personnel on proper storage conditions for medicines in southern Malawi.

Objective: We assessed the temperature variations in pharmacies and medicine storage areas in southern Malawi and conducted a knowledge, attitude and practices survey for personnel who manage medicine stores in various health facilities. Methods: This was a longitudinal study design that used installed Tempmate® thermometers in 27 selected health facilities to record temperatures every 15 min for a period of 9 months. In addition, a questionnaire was used to assess the knowledge, attitude, and practices regarding good pharmaceutical storage. Observations were also made on the storage structures of the facilities and compared with the mean kinetic temperature. Results: Storage temperature ranged from 13.8°C to 42°C with mean kinetic temperature (MKT) being 25.3°C (95% CI 24.4-26.2°C). Mean temperature for public facilities was lower (23.8°C) than the faith-based facilities (25.2°C) and private facilities (26.6°C). In terms of level of health care, lower temperatures were recorded in facilities offering tertiary level of care as compared to secondary and primary care facilities, p < 0.001. For the type of storage facilities, storage-in-a-box unit (SIAB) presented lower temperatures than ordinary storage areas (non-SIAB), p < 0.001. Majority of health workers (69%) had good knowledge on proper storage conditions. Air conditioners and thermometers were available in 88.4 and 76.9% of the facilities, respectively. However, few facilities utilized the air conditioners due to electricity problems. About 46.15% of the participants were able to correctly record temperatures (at least twice a day) for the storage facilities, 23.07% did not properly record while 30.77% of the personnel did not keep temperature records at all. Limited storage space was among the challenges that facilities encounter to maintain proper storage conditions. Conclusion: Despite having the necessary knowledge on proper storage conditions, the pharmacy personnel failed to adhere to good pharmaceutical storage practices due to resource limitations. There is a need for stakeholder interventions such as increasing budget allocation to address the challenges faced by the health facilities.

Burden of and factors associated with poor quality antibiotic, antimalarial, antihypertensive and antidiabetic medicines in Malawi.

OBJECTIVE: To assess the prevalence and factors associated with substandard and falsified (SF) medicines among antibiotic, antimalarial, antihypertensive and antidiabetic medicines in Malawi. METHODS: We conducted a cross-sectional study in 23 public, faith-based and private health facilities in Zomba, Machinga and Nsanje districts. We analyzed oral medicine samples of commonly used medicines among antibiotics, antimalarial, antihypertensive and antidiabetics in accordance with Malawi Essential Medicines List and local treatment guidelines. These medicines were subjected to visual inspection for any defects and screening for the content of active pharmaceutical ingredient and disintegration of dosage units. Samples that failed during screening and at least 10% of those that passed were subjected to pharmacopeia assay and dissolution test for confirmation. We used thin layer chromatography and disintegration test methods provided in the Global Pharma Health Fund minilab® for the screening purposes. We conducted confirmatory test using High-Performance Liquid Chromatography (HPLC) or ultra-violet/visible spectrophotometer and dissolution. RESULTS: Of the 293 medicine samples collected, 14.3% were SF medicines. Among the SF medicines were 12.5% of Amlodipine (1/8), 19.2% of Amoxicillin (5/26), 72.2% of Atenolol (8/11), 21.2% of Ciprofloxacin (7/33), 14.3% of Enalapril (1/7), 44.4% of Flucloxacillin (4/9), and 35.7% of sulfadoxine/ pyrimethamine (10/28). Medicine quality was associated with therapeutic medicine class, stated origin of manufacturer, primary packaging material and geographical location. Antimalarial and antidiabetic medicines were of better quality as compared to antibiotics, odds ratio OR 4.2 (95% CI 1.7-9.49), p < 0.002 and OR 5.6 (95% CI 1.21-26.09), p < 0.028 respectively. In terms of stated country of origin, the prevalence of SF medicines was 30% (15/50), 33% (9/27), 26.7% (4/15) and 6.6% (8/122) for medicines stated to be manufactured in Malawi, China, Kenya and India respectively. CONCLUSION: This study presents the first findings on the assessment of quality of medicines since the establishment of the national pharmacovigilance center in 2019 in Malawi. It is revealed that the problem of SF medicines is not improving and hence the need for further strengthening of quality assurance systems in Malawi.

Tackling antimicrobial resistance across sub-Saharan Africa: current challenges and implications for the future.

INTRODUCTION: Antimicrobial resistance (AMR) is a concern as this increases morbidity, mortality, and costs, with sub-Saharan Africa having the highest rates globally. Concerns with rising AMR have resulted in international, Pan-African, and country activities including the development of national action plans (NAPs). However, there is variable implementation across Africa with key challenges persisting. AREAS COVERED: Consequently, there is an urgent need to document current NAP activities and challenges across sub-Saharan Africa to provide future guidance. This builds on a narrative review of the literature. EXPERT OPINION: All surveyed sub-Saharan African countries have developed their NAPs; however, there is variable implementation. Countries including Botswana and Namibia are yet to officially launch their NAPs with Eswatini only recently launching its NAP. Cameroon is further ahead with its NAP than these countries; though there are concerns with implementation. South Africa appears to have made the greatest strides with implementing its NAP including regular monitoring of activities and instigation of antimicrobial stewardship programs. Key challenges remain across Africa. These include available personnel, expertise, capacity, and resources to undertake agreed NAP activities including active surveillance, lack of focal points to drive NAPs, and competing demands and priorities including among donors. These challenges are being addressed, with further co-ordinated efforts needed to reduce AMR.

A Malawian pharmaceutical response to the COVID-19 Pandemic.

The COVID-19 pandemic has elicited swift and innovative responses due to the severity of the outbreak. Higher education institutions worldwide with pharmacy programs have identified vital gaps in COVID-19 care and has undertaken proactive steps to aid in the fight against the coronavirus. In Malawi, the Kamuzu University of Health Science's Department of Pharmacy initiated the production of a modified formulation of the World Health Organization's (WHO) recommended hand sanitizer. This manufacturing venture involved mobilizing the pharmacy faculty, identifying gaps in supplies and equipment, and utilizing evidenced-based information to create a high-quality sanitation product, which passed the requirements as tested by the Malawi Bureau of Standards. The department of pharmacy is expanding their distribution of the product to meet the needs of frontline healthcare workers and vulnerable populations. With historical issues of accessing care in Malawi and with COVID-19's spread among healthcare workers, this hand sanitizer venture is vital in the public healthcare's system response. The department of pharmacy will continue to lead the pharmacy profession in Malawi to provide targeted interventions in this unprecedented time.
