BACKGROUND: Treating critical illness in resource-limited settings during disease outbreaks is feasible and can save lives. Lack of trained healthcare workers is a major barrier to COVID-19 response. There is an urgent need to train healthcare workers to manage COVID-19. The World Health Organization and International Committee of the Red Cross's Basic Emergency Care course could provide a framework to cross-train personnel for COVID-19 care while strengthening essential health services. METHODS: We conducted a prospective cohort study evaluating the Basic Emergency Care course for healthcare workers from emergency and inpatient units at two hospitals in Sierra Leone, a low-income country in West Africa. Baseline, post-course, and six month assessments of knowledge and confidence were completed. Questions on COVID-19 were added at six months. We compared change from baseline in knowledge scores and proportions of participants "very comfortable" with course skills using paired Student's t-tests and McNemar's exact tests, respectively. RESULTS: We enrolled 32 participants of whom 31 completed pre- and post-course assessments. Six month knowledge and confidence assessments were completed by 15 and 20 participants, respectively. Mean knowledge score post-course was 85% (95% CI: 82% to 88%), which was increased from baseline (53%, 48% to 57%, p-value < 0.001). There was sustained improvement from baseline at six months (73%, 67% to 80%, p-value 0.001). The percentage of participants who were "very comfortable" performing skills increased from baseline for 27 of 34 skills post-training and 13 skills at six months. Half of respondents strongly agreed the course improved ability to manage COVID-19. CONCLUSIONS: This study demonstrates the feasibility of the Basic Emergency Care course to train emergency and inpatient healthcare workers with lasting impact. The timing of the study, at the beginning of the COVID-19 pandemic, provided an opportunity to illustrate the strategic overlap between building human resource capacity for long-term health systems strengthening and COVID-19. Future efforts should focus on integration with national training curricula and training of the trainers for broader dissemination and implementation at scale.

Background: The coronavirus disease 2019 (COVID-19) is a highly infectious respiratory disease. There is no recommended antiviral treatment approved for COVID-19 in Sierra Leone, and supportive care and protection of vital organ function are performed for the patients. This study summarized the clinical characteristics, drug treatments, and risk factors for the severity and prognosis of COVID-19 in Sierra Leone to provide evidence for the treatment of COVID-19. Methods: Data of 180 adult COVID-19 patients from the 34th Military Hospital in Freetown Sierra Leone between March 31, 2020 and August 11, 2020 were retrospectively collected. Patients with severe and critically ill are classified in the severe group, while patients that presented asymptomatic, mild, and moderate disease were grouped in the non-severe group. The clinical and laboratory information was retrospectively collected to assess the risk factors and treatment strategies for severe COVID-19. Demographic information, travel history, clinical symptoms and signs, laboratory detection results, chest examination findings, therapeutics, and clinical outcomes were collected from each case file. Multivariate logistic analysis was adopted to identify the risk factors for deaths. Additionally, the clinical efficacy of dexamethasone treatment was investigated. Results: Seventy-six (42.22%) cases were confirmed with severe COVID-19, while 104 patients (57.78%) were divided into the non-severe group. Fever (56.67%, 102/180) and cough (50.00%, 90/180) were the common symptoms of COVID-19. The death rate was 18.89% (34/180), and severe pneumonia (44.12%, 15/34) and septic shock (23.53%, 8/34) represented the leading reasons for deaths. The older age population, a combination of hypertension and diabetes, the presence of pneumonia, and high levels of inflammatory markers were significantly associated with severity of COVID-19 development (Pâ<â0.05 for all). Altered level of consciousness [odds ratio (OR)â=â56.574, 95% confidence interval (CI) 5.645-566.940, Pâ=â0.001], high levels of neutrophils (ORâ=â1.341, 95%CI 1.109-1.621, Pâ=â0.002) and C-reactive protein (CRP) (ORâ=â1.014, 95%CI 1.003-1.025, Pâ=â0.016) might be indicators for COVID-19 deaths. Dexamethasone treatment could reduce mortality [30.36% (17/56) vs. 50.00% (10/20)] among severe COVID-19 cases, but the results were not statistically significant (Pâ>â0.05). Conclusions: The development and prognosis of COVID-19 may be significantly correlated with consciousness status, and the levels of neutrophils and CRP.
ABSTRACT
This study is an evaluation of the first cohort of patients enrolled in an outpatient non-communicable disease clinic in Kono, Sierra Leone. In the first year, the clinic enrolled 916 patients. Eight months after the enrollment of the last patient, 53% were still active in care, 43% had been lost to follow-up (LTFU) and 4% had defaulted. Of the LTFU patients, 47% only came for the initial enrollment visit and never returned. Treatment outcomes of three patient groups [HTN only (n = 720), DM only (n = 51), and HTN/DM (n = 96)] were analyzed through a retrospective chart review. On average, all groups experienced reductions in blood pressure and/or blood glucose of approximately 10% and 20%, respectively. The proportions of patients with their condition controlled also increased. As NCDs remain underfunded and under-prioritized in low-income countries, the integrated program in Kono demonstrates the possibility of improving outpatient NCD care in Sierra Leone and similar settings.

BACKGROUND: This study aimed at describing the changes in the completeness of documentation and changes in decision to incision time interval of emergency cesarean sections after an audit and feedback project a rural hospital in Sierra Leone. METHODS: We documented and monitored the decision and incision times for emergency cesarean sections over the course of two years. Year one focused on the introduction of the project and year two focused on the continuous monitoring of the project. We compared the completeness of decision to incision data and used the 30-min benchmark as target for the decision to incision time interval. RESULTS: A total of 762 emergency cesarean sections were included. While the completion of decision time data (72%) did not change between the two reporting periods, documentation of incision time increased from 95% to 98% (p < 0.001). Complete documentation for both decision and incision time was available for 540 (70.9%) emergency cesarean sections. The decision to incision time interval decreased from 105 min to 42 min (p < 0.001). The proportion of cesarean sections started within 30 min increased from 8.5% to 37% (p < 0.001). CONCLUSION: Although not all cesarean sections were performed within the 30-min threshold, the decision to incision interval decreased significantly. Improvements in documentation and routine reporting of the decision to incision time interval is recommended.

This study reports on the prevalence and risk factors of chronic HBV among health care workers (HCWs) in a rural secondary hospital in Sierra Leone. Additionally, data on the uptake of HBV vaccination among negatively tested HCWs and on the linkage to care among positively tested HCWs are presented. In December 2019, 781 HCWs were invited to a screening and vaccination campaign at Koidu Government Hospital in Kono District. For each HCW, demographic information and data on their HBV risk history were captured, followed by a hepatitis B surface antigen (HBsAg) test. HCWs with a negative test result were offered an HBV vaccine on the same day, after one and six months. HCWs that were HBsAg positive were linked to a free HBV clinic. In total, 80% (632) of HCWs were screened. Among the screened, 97% had never received an HBV vaccine and 10.3% (n = 65) had chronic HBV. The following characteristics were associated with being HBsAg positive: aged less than 30 years old (aOR 2.17, CI 1.16-4.03, p = 0.01), male gender (aOR 2.0, CI 1.06-3.78, p = 0.03), working experience of 1-4 years (aOR 3.99, CI 1.15-13.73, p = 0.03) and over 9 years (aOR 6.16, CI 1.41-26.9, p = 0.02). For HBsAg-negative HCWs (n = 567), 99.8% (n = 566), 97.5% (n = 553) and 82.7% (n = 469) received their first, second and third dose of the vaccine, respectively. For HBsAg-positive HCWs (n = 65), 73.9% (n = 48) were successfully linked to an HBV clinic for further care. Most HCWs are unvaccinated for HBV, and the HBV prevalence amongst this at-risk group is high. Uptake of vaccination and linkage to care was successful.
ABSTRACT
INTRODUCTION: Currently, there are no data on prevalence and associated risk factors of chronic kidney disease (CKD) among patients with hypertension in rural Sierra Leone. PURPOSE: To estimate the prevalence and associated risk factors of CKD in rural Sierra Leone. PATIENTS AND METHODS: A cross-sectional study of hypertension patients aged between 18 and 75 years attending a non-communicable disease clinic at Koidu Government Hospital, Kono District, Sierra Leone was conducted between February and December 2020. Using systematic random sampling, a structured questionnaire, which comprised of questions on social demographic characteristics and past and current clinical history, was administered followed by measurement of creatinine and urinary protein and glucose. Estimated glomerular filtration rate (eGFR) was estimated using CKD-epidemiology formula without race as a factor. Baseline eGFR between 60-89 min/mL/1.73m2 and <60 min/mL/1.73m2 defined reduced eGFR and renal impairment, respectively. Estimated GFR less than 60 min/mL/1.73m2 measured two times at least 3 months apart was used to define CKD. RESULTS: Ninety-six percent (n = 304) patients out of 317 patients were included in the study. Among all included patients, only 3.9% (n = 12) had eGFR of 90 min/mL/1.73m2 and above. The prevalence of renal impairment and CKD was 52% (158/304, CI 46.2-57.7) and 29.9% (91/304, CI 24.8-34.5), respectively. In adjusted logistic regression analysis, currently taking herbal medications as treatment of hypertension (OR 4.11 (CI 1.14-14.80), p = 0.03) and being overweight and/or obese (OR 2.16 (CI 1.24-3.78), p < 0.001) was associated with CKD. Additionally, receiving some education was associated with a 48% (OR 0.52 (CI 0.29-0.91), p = 0.02) reduced likelihood of CKD. CONCLUSION: The prevalence of renal impairment and CKD is high among hypertensive patients in rural Sierra Leone. CKD was associated with current history of taking herbal medications and being overweight and/or obese. Additionally, CKD was associated with reduced likelihood in patients who received some education.
ABSTRACT
PURPOSE: Hepatitis B virus (HBV) infection is considered a major public health concern for Sierra Leone. Although medical students are at increased occupational risk for HBV infection, little is known about the burden of HBV infection amongst medical students in Sierra Leone. METHODS: As part of a screening and vaccination campaign, a cross-sectional study on prevalence of HBV among medical students in Freetown was conducted in December 2019. Antigen point of care test was used for HBV screening and data on students' risk history and demographics were collected. Additionally, for students diagnosed positive with HBV, linkage to care and initial assessment data after diagnosis was collected from the HBV clinic they were linked to. RESULTS: One hundred and fifty-seven medical students (77.3%) from year three to six were screened for HBV infection. Almost all students (98.1%) had never been vaccinated against HBV and more than half (56.7%) reported a history of needle stick injuries. The prevalence of HBV infection (Hepatitis B surface antigen (HBsAg) positivity) was 10.2% (n = 16). Among HBsAg positive students, 75% (n = 12) were successfully enrolled at chronic HBV clinic within three months of diagnosis. Only one student had evidence of liver cirrhosis and was started on treatment with Tenofovir diproxil fumarate. CONCLUSION: The prevalence of HBV infection is high among medical students in Sierra Leone. Despite the high prevalence, most of the students linked to care had no evidence of severe liver disease.
ABSTRACT
OBJECTIVES: In Sierra Leone, very little data are available on hepatitis B virus (HBV) and hepatitis C virus (HCV) prevalence. Blood donor screening permits estimation of the prevalence of transfusion transmissible infections in a general open population. We analyzed blood donor data in Sierra Leone to estimate national viral hepatitis prevalence and identify risk factors for hepatitis infection among the donor population. METHODS: We conducted a retrospective data analysis in five government hospitals. We collected HBV and HCV screening results, donor demographics, and donation type (family replacement or voluntary donor; first-time or repeat). Univariate and multivariate analyses were performed to determine associations between infections and socio-demographic factors. RESULTS: The number of donors screened was 29,713. The overall prevalence was: 10.8% (3200) for HBV and 1.2% (357) for HCV. HBV infection was most strongly associated with male sex (p: <0.0001) and younger age (p: <0.0004 for the 22-27 age group). Both HBV and HCV infection were higher in certain locations. CONCLUSION: Our findings stress the presence of viral hepatitis infection throughout the country and the need to invest in safe blood services, vaccination and treatment of viral hepatitis at the national level.

The Corona Virus Disease 2019 (COVID-19) pandemic has rapidly spread in Africa, with a total of 474,592 confirmed cases by 11th July 2020. Consequently, all policy makers and health workers urgently need to be trained and to access the most credible information to contain and mitigate its impact. While the need for rapid training and information dissemination has increased, most of Africa is implementing public health social and physical distancing measures. Responding to this context requires broad partnerships and innovative virtual approaches to disseminate new insights, share best practices, and create networked communities of practice for all teach, and all learn. The World Health Organization (WHO)-Africa region, in collaboration with the Extension for Community Health Outcome (ECHO) Institute at the University of New Mexico Health Sciences Center (UNM HSC), the West Africa college of nurses and the East Central and Southern Africa college of physicians, private professional associations, academia and other partners has embarked on a virtual training programme to support the containment of COVID-19. Between 1st April 2020 and 10th July 2020, about 7,500 diverse health professionals from 172 locations in 58 countries were trained in 15 sessions. Participants were from diverse institutions including: central ministries of health, WHO country offices, provincial and district hospitals and private medical practitioners. A range of critical COVID-19 preparedness and response interventions have been reviewed and discussed. There is a high demand for credible information from credible sources about COVID-19. To mitigate the "epidemic of misinformation" partnerships for virtual trainings and information dissemination leveraging existing learning platforms and networks across Africa will augment preparedness and response to COVID-19.

We describe a case series of 35 Ebola virus disease (EVD) survivors during the epidemic in West Africa who had neurologic and accompanying psychiatric sequelae. Survivors meeting neurologic criteria were invited from a cohort of 361 EVD survivors to attend a preliminary clinic. Those whose severe neurologic features were documented in the preliminary clinic were referred for specialist neurologic evaluation, ophthalmologic examination, and psychiatric assessment. Of 35 survivors with neurologic sequelae, 13 had migraine headache, 2 stroke, 2 peripheral sensory neuropathy, and 2 peripheral nerve lesions. Of brain computed tomography scans of 17 patients, 3 showed cerebral and/or cerebellar atrophy and 2 confirmed strokes. Sixteen patients required mental health followup; psychiatric disorders were diagnosed in 5. The 10 patients who experienced greatest disability had co-existing physical and mental health conditions. EVD survivors may have ongoing central and peripheral nervous system disorders, including previously unrecognized migraine headaches and stroke.

OBJECTIVES: A central pillar in the response to the 2014 Ebola virus disease (EVD) epidemic in Sierra Leone was the role of Ebola Holding Units (EHUs). These units isolated patients meeting a suspect case definition, tested them for EVD, initiated appropriate early treatment and discharged negative patients to onward inpatient care or home. Positive patients were referred to Ebola Treatment Centres. We aimed to estimate the risk of nosocomial transmission within these EHUs. METHODS: We followed up a cohort of 543 patients discharged with a negative EVD test from five EHUs in the Western Area, Sierra Leone, and examined all line-listed subsequent EVD tests from any facility in the Western Area to see whether the patient was retested within 30 days, matching by name, age and address. We defined possible readmissions as having the same name and age but uncertain address, and confirmed readmissions where name, age and address matched. RESULTS: We found a positive readmission rate of 3.3% (18 cases), which included 1.5% confirmed readmissions (8 cases) and 1.8% possible readmissions (10 cases). This is lower than rates previously reported. We cannot ascertain whether EVD was acquired within the EHUs or from re-exposure in the community. No demographic or clinical variables were identified as risk factors for positive readmission, likely due to our small sample size. CONCLUSIONS: These findings support the EHU model as a safe method for isolation of suspect EVD patients and their role in limiting the spread of EVD.

The 2014-2015 West African outbreak of Ebola Virus Disease (EVD) claimed the lives of more than 11,000 people and infected over 27,000 across seven countries. Traditional approaches to containing EVD proved inadequate and new approaches for controlling the outbreak were required. The Ministry of Health & Sanitation and King's Sierra Leone Partnership developed a model for Ebola Holding Units (EHUs) at Government Hospitals in the capital city Freetown. The EHUs isolated screened or referred suspect patients, provided initial clinical care, undertook laboratory testing to confirm EVD status, referred onward positive cases to an Ebola Treatment Centre or negative cases to the general wards, and safely stored corpses pending collection by burial teams. Between 29th May 2014 and 19th January 2015, our five units had isolated approximately 37% (1159) of the 3097 confirmed cases within Western Urban and Rural district. Nosocomial transmission of EVD within the units appears lower than previously documented at other facilities and staff infection rates were also low. We found that EHUs are a flexible and effective model of rapid diagnosis, safe isolation and early initial treatment. We also demonstrated that it is possible for international partners and government facilities to collaborate closely during a humanitarian crisis.
ABSTRACT
Evidence to inform decontamination practices at Ebola holding units (EHUs) and treatment centres is lacking. We conducted an audit of decontamination procedures inside Connaught Hospital EHU in Freetown, Sierra Leone, by assessing environmental swab specimens for evidence of contamination with Ebola virus by RT-PCR. Swabs were collected following discharge of Ebola Virus Disease (EVD) patients before and after routine decontamination. Prior to decontamination, Ebola virus RNA was detected within a limited area at all bedside sites tested, but not at any sites distant to the bedside. Following decontamination, few areas contained detectable Ebola virus RNA. In areas beneath the bed there was evidence of transfer of Ebola virus material during cleaning. Retraining of cleaning staff reduced evidence of environmental contamination after decontamination. Current decontamination procedures appear to be effective in eradicating persistence of viral RNA. This study supports the use of viral swabs to assess Ebola viral contamination within the clinical setting. We recommend that regular refresher training of cleaning staff and audit of environmental contamination become standard practice at all Ebola care facilities during EVD outbreaks.

BACKGROUND: The size of the west African Ebola virus disease outbreak led to the urgent establishment of Ebola holding unit facilities for isolation and diagnostic testing of patients with suspected Ebola virus disease. Following the onset of the outbreak in Sierra Leone, patients presenting to Connaught Hospital in Freetown were screened for suspected Ebola virus disease on arrival and, if necessary, were admitted to the on-site Ebola holding unit. Since demand for beds in this unit greatly exceeded capacity, we aimed to improve the selection of patients with suspected Ebola virus disease for admission by identifying presenting clinical characteristics that were predictive of a confirmed diagnosis. METHODS: In this retrospective cohort study, we recorded the presenting clinical characteristics of suspected Ebola virus disease cases admitted to Connaught Hospital's Ebola holding unit. Patients were subsequently classified as confirmed Ebola virus disease cases or non-cases according to the result of Ebola virus reverse-transcriptase PCR (EBOV RT-PCR) testing. The sensitivity, specificity, positive predictive value, negative predictive value, and likelihood ratio of every clinical characteristic were calculated, to estimate the diagnostic accuracy and predictive value of each clinical characteristic for confirmed Ebola virus disease. RESULTS: Between May 29, 2014, and Dec 8, 2014, 850 patients with suspected Ebola virus disease were admitted to the holding unit, of whom 724 had an EBOV RT-PCR result recorded and were included in the analysis. In 464 (64%) of these patients, a diagnosis of Ebola virus disease was confirmed. Fever or history of fever (n=599, 83%), intense fatigue or weakness (n=495, 68%), vomiting or nausea (n=365, 50%), and diarrhoea (n=294, 41%) were the most common presenting symptoms in suspected cases. Presentation with intense fatigue, confusion, conjunctivitis, hiccups, diarrhea, or vomiting was associated with increased likelihood of confirmed Ebola virus disease. Three or more of these symptoms in combination increased the probability of Ebola virus disease by 3·2-fold (95% CI 2·3-4·4), but the sensitivity of this strategy for Ebola virus disease diagnosis was low. In a subgroup analysis, 15 (9%) of 161 confirmed Ebola virus disease cases reported neither a history of fever nor a risk factor for Ebola virus disease exposure. INTERPRETATION: Discrimination of Ebola virus disease cases from patients without the disease is a major challenge in an outbreak and needs rapid diagnostic testing. Suspected Ebola virus disease case definitions that rely on history of fever and risk factors for Ebola virus disease exposure do not have sufficient sensitivity to identify all cases of the disease. FUNDING: None.
