Antibiotic use among hospitalised patients in Sierra Leone: a national point prevalence survey using the WHO survey methodology

OBJECTIVE

Inappropriate use of antibiotics is a major driver of antibiotic resistance. A few studies conducted in Africa have documented that about half of hospitalised patients who receive antibiotics should not have received them. A few hospital-based studies that have been conducted in Sierra Leone have documented a high usage of antibiotics in hospitals. Therefore, we conducted a nationwide point prevalence survey on antibiotic use among hospitalised patients in Sierra Leone.

DESIGN

We conducted a hospital-based, cross-sectional survey on the use of antibiotics using the WHO point prevalence survey methodology.

SETTING

The study was conducted in 26 public and private hospitals that are providing inpatient healthcare services.

PARTICIPANTS

All patients admitted to paediatric and adult inpatient wards before or at 08:00 on the survey date were enrolled.

OUTCOME MEASURES

Prevalence of antibiotic use, antibiotics Access, Watch and Reserve (AWaRe) categorisation, indication for antibiotic use prevalence and proportion of bacteria culture done.

RESULTS

Of the 1198 patient records reviewed, 883 (73.7%, 95% CI 71.1% to 76.2%) were on antibiotics. Antibiotic use was highest in the paediatric wards (306, 85.7%), followed by medical wards (158, 71.2%), surgical wards (146, 69.5%), mixed wards (97, 68.8%) and lowest in the obstetrics and gynaecology wards (176, 65.7%). The most widely prescribed antibiotics were metronidazole (404, 22.2%), ceftriaxone (373, 20.5%), ampicillin (337, 18.5%), gentamicin (221, 12.1%) and amoxicillin (90, 5.0%). Blood culture was only done for one patient and antibiotic treatments were given empirically. The most common indication for antibiotic use was community-acquired infection (484, 51.9%) followed by surgical prophylaxis (222, 23.8%).

CONCLUSION

There was high usage of antibiotics in hospitals in Sierra Leone as the majority of patients admitted received an antibiotic. This has the potential to increase the burden of antibiotic resistance in the country. We, therefore, recommend the establishment of hospital antimicrobial stewardship programmes according to the WHO core components.

Hand Hygiene Practices and Promotion in Public Hospitals in Western Sierra Leone: Changes Following Operational Research in 2021

Hand hygiene is the most important intervention for preventing healthcare-associated infections and can reduce preventable morbidity and mortality. We described the changes in hand hygiene practices and promotion in 13 public hospitals (six secondary and seven tertiary) in the Western Area of Sierra Leone following the implementation of recommendations from an operational research study. This was a "before and after" observational study involving two routine cross-sectional assessments using the WHO hand hygiene self-assessment framework (HHSAF) tool. The overall mean HHSAF score changed from 273 in May 2021 to 278 in April 2023; it decreased from 278 to 250 for secondary hospitals but increased from 263 to 303 for tertiary hospitals. The overall mean HHSAF score and that of the tertiary hospitals remained at the "intermediate" level, while secondary hospitals declined from "intermediate" to "basic" level. The mean score increased for the "system change" and "institutional safety climate" domains, decreased for "training and education" and "reminders in the workplace" domains, and remained the same for the "evaluation and feedback" domain. Limited resources for hand hygiene promotion, lack of budgetary support, and formalized patient engagement programs are the persistent gaps that should be addressed to improve hand hygiene practices and promotion.

Quality of Reporting of Adverse Drug Reactions to Antimicrobials Improved Following Operational Research: A before-and-after Study in Sierra Leone (2017-2023)

Background: The quality of pharmacovigilance data is important for guiding medicine safety and clinical practice. In baseline and follow-up studies after introducing interventions to improve the quality of reporting of Individual Case Safety Reports (ICSRs) in Sierra Leone, we compared (a) timeliness and completeness of reporting and (b) patient outcomes classified as 'recovering'. Methods: Baseline (January 2017-December 2021) and follow-up (June 2022-April 2023) studies of ICSRs in the national pharmacovigilance database. Interventions introduced following recommendations from the baseline study included: updating standard operating procedures and guidelines, setting performance targets follow-up of patient outcomes, and training. Results: There were 566 ICSRs in the baseline study and 59 in the follow-up study. Timelines (reporting < 30 days) improved by five-fold (10% at baseline to 47% in follow-up). For the completeness of variables in ICSRs (desired threshold ≥ 90%),this was 44% at baseline and increased to 80% in the follow-up study. 'Recovering' outcomes reduced from 36% (baseline study) to 3% (follow-up study, p < 0.001). Conclusions: Significant improvements in timeliness, completeness, and validation of ICSRs were observed following operational research in Sierra Leone. While enhancing pharmacovigilance and patient safety, this study highlights the important synergistic role operational research can play in improving monitoring and evaluation systems.

Have Hand Hygiene Practices in Two Tertiary Care Hospitals, Freetown, Sierra Leone, Improved in 2023 following Operational Research in 2021?

In 2021, an operational research study in two tertiary hospitals in Freetown showed poor hand hygiene compliance. Recommended actions were taken to improve the situation. Between February-April 2023, a cross-sectional study was conducted in the same two hospitals using the World Health Organization hand hygiene tool to assess and compare hand hygiene compliance with that observed between June-August 2021. In Connaught hospital, overall hand hygiene compliance improved from 51% to 60% (p < 0.001), and this applied to both handwash actions with soap and water and alcohol-based hand rub. Significant improvements were found in all hospital departments and amongst all healthcare worker cadres. In 34 Military Hospital (34MH), overall hand hygiene compliance decreased from 40% to 32% (p < 0.001), with significant decreases observed in all departments and amongst nurses and nursing students. The improvements in Connaught Hospital were probably because of more hand hygiene reminders, better handwash infrastructure and more frequent supervision assessments, compared with 34MH where interventions were less well applied, possibly due to the extensive hospital reconstruction at the time. In conclusion, recommendations from operational research in 2021 contributed towards the improved distribution of hand hygiene reminders, better handwash infrastructure and frequent supervision assessments, which possibly led to improved hand hygiene compliance in one of the two hospitals. These actions need to be strengthened, scaled-up and guided by ongoing operational research to promote good hand hygiene practices elsewhere in the country.

Assessing Changes in Surgical Site Infections and Antibiotic Use among Caesarean Section and Herniorrhaphy Patients at a Regional Hospital in Sierra Leone Following Operational Research in 2021

Surgical site infections (SSIs) are a major public health threat to the success of surgery. This study assessed changes in SSIs and use of antibiotics among caesarean section (CS) and herniorrhaphy patients at a regional hospital in Sierra Leone following operational research. This was a comparative before and after study using routine hospital data. The study included all the CS and herniorrhaphy patients who underwent surgery between two time periods. Of the seven recommendations made in the first study, only one concerning improving the hospital's records and information system was fully implemented. Three were partially implemented and three were not implemented. The study population in both studies showed similar socio-demographic characteristics. The use of postoperative antibiotics for herniorrhaphy in both studies remained the same, although a significant increase was found for both pre- and postoperative antibiotic use in the CS patients, 589/596 (98.8%) in 2023 and 417/599 (69.6%) in 2021 (p < 0.001). However, a significant decrease was observed in the overall incidence of SSIs, 22/777 (2.8%) in 2023 and 46/681 (6.7%) in 2021 (p < 0.001), and the incidence of SSIs among the CS patients, 15/596 (2.5%) in 2023 and 45/599 (7.5%) in 2021 (p < 0.001). The second study highlights the potential value of timely assessment of the implementation of recommendations following operational research.

Improvement in Infection Prevention and Control Compliance at the Three Tertiary Hospitals of Sierra Leone following an Operational Research Study

Implementing infection prevention and control (IPC) programmes in line with the World Health Organization's (WHO) eight core components has been challenging in Sierra Leone. In 2021, a baseline study found that IPC compliance in three tertiary hospitals was sub-optimal. We aimed to measure the change in IPC compliance and describe recommended actions at these hospitals in 2023. This was a 'before and after' observational study using two routine cross-sectional assessments of IPC compliance using the WHO IPC Assessment Framework tool. IPC compliance was graded as inadequate (0-200), basic (201-400), intermediate (401-600), and advanced (601-800). The overall compliance scores for each hospital showed an improvement from 'Basic' in 2021 to 'Intermediate' in 2023, with a percentage increase in scores of 16.9%, 18.7%, and 26.9% in these hospitals. There was improved compliance in all core components, with the majority in the 'Intermediate' level for each hospital IPC programme. Recommended actions including the training of healthcare workers and revision of IPC guidelines were undertaken, but a dedicated IPC budget and healthcare-associated infection surveillance remained as gaps in 2023. Operational research is valuable in monitoring and improving IPC programme implementation. To reach the 'Advanced' level, these hospitals should establish a dedicated IPC budget and develop long-term implementation plans.

Improvement in Infection Prevention and Control Performance Following Operational Research in Sierra Leone: A Before (2021) and After (2023) Study

INTRODUCTION

Infection prevention and control (IPC) is crucial to limit health care-associated infections and antimicrobial resistance. An operational research study conducted in Sierra Leone in 2021 reported sub-optimal IPC performance and provided actionable recommendations for improvement.

METHODS

This was a before-and-after study involving the national IPC unit and all twelve district-level secondary public hospitals. IPC performance in 2021 (before) and in 2023 (after) was assessed using standardized World Health Organization checklists. IPC performance was graded as: inadequate (0-25%), basic (25.1-50%), intermediate (50.1-75%), and advanced (75.1-100%).

RESULTS

The overall IPC performance in the national IPC unit moved from intermediate (58%) to advanced (78%), with improvements in all six core components. Four out of six components achieved advanced levels when compared to the 2021 levels. The median score for hospitals moved from basic (50%) to intermediate (59%), with improvements in six of eight components. Three of four gaps identified in 2021 at the national IPC unit and four of seven at hospitals had been addressed by 2023.

CONCLUSIONS

The study highlights the role of operational research in informing actions that improved IPC performance. There is a need to embed operational research as part of the routine monitoring of IPC programs.

Antibiotic use and consumption in Freetown, Sierra Leone: A baseline report of prescription stewardship in outpatient clinics of three tertiary hospitals

Objective

As there are no country-representative data on bacterial sensitivities to guide antimicrobial stewardship (AMS) interventions, an AMS programme was established in the outpatient clinics of three tertiary hospitals in Freetown, Sierra Leone.

Methods

The study employed a cross-sectional design to collect antibiotic prescribing data from 370 pregnant women and lactating mothers, 314 children and 229 regular patients in the outpatient clinics of the Princess Christian Maternity Hospital (PCMH), Ola During Children's Hospital and Connaught Hospital (CH), respectively, in April 2022. All data were analysed using Stata Version 16.

Results

Of 913 patients, most were female (n=635, 69.5%), treated at PCMH (n=370, 40.5%) and had a bacterial infection (n=661, 72.4%). The indication for prescribing antibiotics was inappropriate in 252 (27.6%) patients. Of the 1236 prescriptions, 393 (31.8%) were made at CH. The duration of antibiotic use was not stated in 230 (18.6%) prescriptions. Overall antibiotic consumption was 55.3 defined daily doses per 1000 outpatient-days.

Conclusion

Gaps in antibiotic prescriptions were identified in the outpatient clinics of three national referral hospitals in Sierra Leone. In order to combat antimicrobial resistance, AMS interventions are needed to reduce the prescription of antibiotics for inappropriate indications or without specified duration.

Evaluation of Drinking Water Quality and Bacterial Antibiotic Sensitivity in Wells and Standpipes at Household Water Points in Freetown, Sierra Leone

Water quality surveillance can help to reduce waterborne diseases. Despite better access to safe drinking water in Sierra Leone, about a third of the population (3 million people) drink water from unimproved sources. In this cross-sectional study, we collected water samples from 15 standpipes and 5 wells and measured the physicochemical and bacteriological water quality, and the antimicrobial sensitivity of Escherichia coli (E. coli) in two communities in Freetown, Sierra Leone in the dry and wet seasons in 2021. All water sources were contaminated with E. coli, and all five wells and 25% of standpipes had at least an intermediate risk level of E. coli. There was no antimicrobial resistance detected in the E. coli tested. The nitrate level exceeded the WHO’s recommended standard (>10 parts per million) in 60% of the wells and in less than 20% of the standpipes. The proportion of samples from standpipes with high levels of total dissolved solids (>10 Nephelometric Turbidity Units) was much higher in the rainy season (73% vs. 7%). The level of water contamination is concerning. We suggest options to reduce E. coli contamination. Further research is required to identify where contamination of the water in standpipes is occurring.

Achieving Minimum Standards for Infection Prevention and Control in Sierra Leone: Urgent Need for a Quantum Leap in Progress in the COVID-19 Era!

INTRODUCTION

Good Infection prevention and control (IPC) is vital for tackling antimicrobial resistance and limiting health care-associated infections. We compared IPC performance before (2019) and during the COVID-19 (2021) era at the national IPC unit and all regional (4) and district hospitals (8) in Sierra Leone.

METHODS

Cross-sectional assessments using standardized World Health Organizations IPC checklists. IPC performance scores were graded as inadequate = 0-25%, basic = 25.1-50%, intermediate = 50.1-75%, and advanced = 75.1-100%.

RESULTS

Overall performance improved from 'basic' to 'intermediate' at the national IPC unit (41% in 2019 to 58% in 2021) and at regional hospitals (37% in 2019 to 54% in 2021) but remained 'basic' at district hospitals (37% in 2019 to 50% in 2021). Priority gaps at the national IPC unit included lack of: a dedicated IPC budget, monitoring the effectiveness of IPC trainings and health care-associated infection surveillance. Gaps at hospitals included no assessment of hospital staffing needs, inadequate infrastructure for IPC and lack of a well-defined monitoring plan with clear goals, targets and activities.

CONCLUSION

Although there is encouraging progress in IPC performance, it is slower than desired in light of the COVID-19 pandemic. There is urgent need to mobilize political will, leadership and resources and make a quantum leap forward.

Infection Prevention and Control in Three Tertiary Healthcare Facilities in Freetown, Sierra Leone during the COVID-19 Pandemic: More Needs to Be Done!

Infection Prevention and Control (IPC) measures are critical to the reduction in healthcare-associated infections, especially during pandemics, such as that of COVID-19. We conducted a hospital-based cross-sectional study in August 2021 at Connaught Hospital, Princess Christian Maternity Hospital and Ola During Children's Hospital located in Freetown, Sierra Leone. We used the World Health Organization's Infection Prevention and Control Assessment Framework Tool to assess the level of IPC compliance at these healthcare facilities. The overall IPC compliance score at Connaught Hospital was 323.5 of 800 points, 313.5 of 800 at Ola During Children's Hospital, 281 of 800 at Princess Christian Maternity Hospital, implying a 'Basic' IPC compliance grade. These facilities had an IPC program, IPC committees and dedicated IPC focal persons. However, there were several challenges, including access to safe and clean water and insufficient quantities of face masks, examination gloves and aprons. Furthermore, there was no dedicated budget or no healthcare-associated infection (HAI) surveillance, and monitoring/audit of IPC practices were weak. These findings are of concern during the COVID-19 era, and there is an urgent need for both financial and technical support to address the gaps and challenges identified.

Antibiotic Use in Suspected and Confirmed COVID-19 Patients Admitted to Health Facilities in Sierra Leone in 2020-2021: Practice Does Not Follow Policy

Inappropriate use of antibiotics during the COVID-19 pandemic has the potential to increase the burden of antimicrobial resistance. In this study, we report on the prevalence of antibiotic use and its associated factors among suspected and confirmed COVID-19 patients admitted to 35 health facilities in Sierra Leone from March 2020-March 2021. This was a cross-sectional study using routinely collected patient data. Of 700 confirmed COVID-19 patients, 47% received antibiotics. The majority (73%) of the antibiotics belonged to the 'WATCH' group of antibiotics, which are highly toxic and prone to resistance. The most frequently prescribed antibiotics were azithromycin, ceftriaxone, amoxicillin, metronidazole, and amoxicillin-clavulanic acid. Antibiotic use was significantly higher in patients aged 25-34 years than in those with severe disease. Of 755 suspected COVID-19 patients, 61% received antibiotics, of which the majority (58%) belonged to the 'WATCH' category. The most frequently prescribed antibiotics were ceftriaxone, metronidazole, azithromycin, ciprofloxacin, and amoxycillin. The prevalence of antibiotic use among suspected and confirmed COVID-19 patients admitted to healthcare facilities in Sierra Leone was high and not in line with national and WHO case management guidelines. Training of health care providers, strengthening of antimicrobial stewardship programs, and microbiological laboratory capacity are urgently needed.

How Well Are Hand Hygiene Practices and Promotion Implemented in Sierra Leone? A Cross-Sectional Study in 13 Public Hospitals

Healthcare-associated infections (HAIs) result in millions of avoidable deaths or prolonged lengths of stay in hospitals and cause huge economic loss to health systems and communities. Primarily, HAIs spread through the hands of healthcare workers, so improving hand hygiene can reduce their spread. We evaluated hand hygiene practices and promotion across 13 public health hospitals (six secondary and seven tertiary hospitals) in the Western Area of Sierra Leone in a cross-sectional study using the WHO hand hygiene self-Assessment framework in May 2021. The mean score for all hospitals was 273 ± 46, indicating an intermediate level of hand hygiene. Nine hospitals achieved an intermediate level and four a basic level. More secondary hospitals 5 (83%) were at the intermediate level, compared to tertiary hospitals 4 (57%). Tertiary hospitals were poorly rated in the reminders in workplace and institutional safety climate domains but excelled in training and education. Lack of budgets to support hand hygiene implementation is a priority gap underlying this poor performance. These gaps hinder hand hygiene practice and promotion, contributing to the continued spread of HAIs. Enhancing the distribution of hand hygiene resources and encouraging an embedded culture of hand hygiene practice in hospitals will reduce HAIs.
