Maternal death surveillance and response system evaluation in Makonde District, Zimbabwe, 2021.

BACKGROUND: Maternal mortality is of global concern, almost 800 women die every day due to maternal complications. The maternal death surveillance and response (MDSR) system is one strategy designed to reduce maternal mortality. In 2021 Makonde District reported a maternal mortality ratio of 275 per 100 000 and only sixty-two percent of deaths recorded were audited. We evaluated the MDSR system in Makonde to assess its performance. METHODS: A descriptive cross-sectional study was conducted using the CDC guidelines for evaluating public health surveillance systems. An Interviewer-administered questionnaire was used to collect data from 79 health workers involved in MDSR and healthcare facilities. All maternal death notification forms, weekly disease surveillance forms, and facility monthly summary forms were reviewed. We assessed health workers' knowledge, usefulness and system attributes. RESULTS: We interviewed 79 health workers out of 211 workers involved in MDSR and 71 (89.9%) were nurses. The median years in service was 8 (IQR: 4-12). Overall health worker knowledge (77.2%) was good. Ninety-three percent of the deaths audited were of avoidable causes. Twelve out of the thirty-eight (31.6%) facilities were using electronic health records system. Feedback and documented shared information were evident at four facilities (21%) including the referral hospital. Nineteen (67.9%) out of 28 maternal death notification forms were completed within seven days and none were submitted to the PMD on time. CONCLUSION: The MDSR system was acceptable and simple but not timely, stable and complete. Underutilization of the electronic health system, work load, poor documentation and data management impeded performance of the system. We recommended appointment of an MDSR focal person, sharing audit minutes and improved data management.

Tuberculosis cohort analysis in Zimbabwe: The need to strengthen patient follow-up throughout the tuberculosis care cascade.

INTRODUCTION: Globally people with tuberculosis (TB) continue to be missed each year. They are either not diagnosed or not reported which indicates possible leakages in the TB care cascade. Zimbabwe is not spared with over 12000 missed cases in 2020. A preliminary review of TB treatment outcomes indicated patient leakages throughout the presumptive cascade and undesirable treatment outcomes in selected cities. Chegutu District had pre-diagnosis and pretreatment losses to follow-up while Mutare City among others had 22.0% of outcomes not evaluated in the second quarter of 2021, and death rates as high as 14% were recorded in Gweru District. The problem persists despite training on data analysis and use. The TB cohorts were analysed to determine the performance of the care cascade and the spatial distribution of treatment outcomes in Zimbabwe. METHODS: Using data from district health information software version 2.3 (DHIS2.3), a secondary data analysis of 2020 drug-sensitive (DS) TB treatment cohorts was conducted. We calculated the percentage of pre-diagnosis, and pre-treatment loss to follow-up (LTFU). For TB treatment outcomes, 'cured' and 'treatment completed' were categorized as treatment success, while 'death', 'loss to follow-up (LTFU), and 'not evaluated' were categorized as undesirable outcomes. Univariate analysis of the data was conducted where frequencies were calculated, and data was presented in graphs for the cascade, treatment success, and undesirable outcomes while tables were created for the description of study participants and data quality. QGIS was used to generate maps showing undesirable treatment outcomes. RESULTS: An analysis of national data found 107583 people were presumed to have TB based on symptomatic screening and or x-ray and 21.4% were LTFU before the specimen was investigated. Of the 84534 that got tested, 10.0% did not receive their results. The treatment initiation rate was 99.1%. Analysis of treatment outcomes done at the provincial level showed that Matabeleland South Province had the lowest treatment success rate of 77.3% and high death rates were recorded in Matabeleland South (30.0%), Masvingo (27.3%), and Matabeleland North (26.1%) provinces. Overall, there were high percentages of not-evaluated treatment outcomes. CONCLUSION: Pre-diagnosis LTFU was high, and high death and loss to follow-up rates were prevalent in provinces with artisanal and small-scale mining (ASM) activities. Unevaluated treatment outcomes were also prevalent and data quality remains a challenge within the national TB control program. We recommended strengthening patient follow-up at all levels within the TB care cascade, strengthening capacity-building for data analysis and use, further analysis to determine factors associated with undesirable outcomes and a study on why LTFU remains high.

Factors associated with COVID-19 fatality among patients admitted in Mashonaland West Province, Zimbabwe 2020-2022: a secondary data analysis.

Introduction: approximately 15% of COVID-19 patients develop symptoms necessitating admission. From 2020 to 2022, Mashonaland West Province had an institutional case fatality rate of 23% against a national rate of 7%. Therefore, we evaluated the COVID-19 admissions in the province to determine the factors associated with COVID-19 mortality. Methods: we conducted an analytical cross-sectional study based on secondary data from isolation centers across the province using all 672 death audit forms and patient records. We obtained data on patient demographics, signs and symptoms, clinical management and oxygen therapy administered, among other things. Data were entered into an electronic form and imported into Epi-info 7 for analysis bivariate and multivariate conducted. Results: we found that being an older man, aOR 1.04 (1.03-1.05), who had diabetes aOR 6.0 (95% CI: 3.8-9.2) and hypertension aOR 4.5 (95% CI: 2.8-6.5) were independent risk factors. Patients put on dexamethasone aOR 2.4 (95% CI: 1.6-3.4) and heparin/clexane aOR 1.6 (95% CI: 1.1-2.2) had a higher mortality risk. However, vitamin C aOR 0.48 (95% CI: 0.31-0.71) and oxygen therapy aOR 0.14 (95% CI: 0.10-0.19) and being pregnant aOR 0.06 (95% CI: 0.02-0.14) were protective. Conclusion: mortality risk increased in older male patients with comorbidities and with those on dexamethasone and heparin therapy. Oxygen therapy and vitamin C were protective. There is a need to conduct further study of the source of these variations in risk across patients to establish the true impact of differences in individuals' mortality.

Predictors of COVID-19 infection among health care workers in Harare City, Zimbabwe, 2021.

Introduction: preventing COVID-19 infection among health workers maintains the health system capacity and reduces secondary transmission. Of 506 health workers tested for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection in Harare City between December 2020 and February 2021 (second wave), 128 (25%) tested positive, affecting service delivery. We investigated factors associated with COVID-19 infection and described breakthrough infections among health workers. Methods: we conducted a cross-sectional study in Harare City. Interviews were conducted with 467 health workers to determine behavioral, occupational, and non-occupational factors associated with COVID-19 infection. Fifteen key informants were interviewed to verify responses. Records and line-list were reviewed to verify cases, outcomes, and vaccination status. Observations were done to check adherence to prevention measures. Epi-info generated means, frequencies, proportions and conducted univariate, bivariate and multivariate analysis. Statistical significance was at p-value<0.05. Results: we interviewed 467 health workers, 166 (35.5%) had a history of COVID-19 infection. Females were the majority 357 (76.4%), mostly nurses 200 (42.8%). Those not trained on infection control measures in the past six months (aOR=2.13; 95%CI 1.06-4.27; p=0.03), not observing social distance at mealtimes (aOR=6.33; 95%CI 3.36-11.89; p<0.01), having a household COVID-19 case (aOR=9.03; 95%CI 3.93-20.76; p<0.01) and not properly wearing facemasks (aOR=16.68; 95%CI 9.39-29.61; p<0.01) were significantly associated COVID-19 infection. Of 378 health workers fully vaccinated, 39 (10.3%) had breakthrough infections. Most with breakthrough infections, 33 (84.6%) had asymptomatic or mild disease. One death was recorded, a female, not vaccinated, with uncontrolled diabetes. Conclusion: predictors of COVID-19 infection among health workers were, no training on infection and prevention and control (IPC) measures, lack of social distancing at mealtimes, improper use of facemasks, and having a COVID-19 case at household level. We conducted refresher training to strengthen infection control measures.

Anthrax outbreak investigation in Tengwe, Mashonaland West Province, Zimbabwe, 2022.

BACKGROUND: Anthrax continues to be a disease of public health concern in Zimbabwe. Between December 2021 and February 2022, Tengwe reported 36 cases of human anthrax. Gastrointestinal anthrax has the potential to cause serious outbreaks leading to loss of human life. We investigated the outbreak, identified the risk factors using one health approach to inform outbreak control. MATERIALS AND METHODS: We conducted descriptive analysis of the outbreak and a 1:2 unmatched case control study to identify risk factors for anthrax. A case was any Tengwe resident who developed an ulcer and/or abdominal symptoms and epidemiologically linked to a confirmed environmental exposure. Validated, structured interviewer-administered questionnaires were used to collect data from the cases and neighbourhood controls. Soil and dried meat samples were collected for laboratory investigations. District preparedness and response was assessed using a checklist. Data was analysed using Epi Info version 7.2.5. The odds of exposure were calculated for each risk factor examined. Multivariable logistic regression analysis was performed to identify the independent factors associated with contracting anthrax. RESULTS: Through active case finding we identified 36 cases, 31 were interviewed. Twenty-one (67.7%) were males. The median age was 33 years (Inter quartile range: 22-54). Nineteen (61.2%) cases presented with abdominal symptoms with zero deaths reported. The independent risk factor for contracting anthrax was eating under-cooked meat (aOR = 12.2, 95% CI: 1.41-105.74, p = 0.023). All samples collected tested positive for anthrax. No livestock vaccinations or zoonotic meetings were being conducted prior to the outbreak. Notification of the outbreak was done 11 days after index case presentation however one health response was instituted within 24 hours. CONCLUSION: The anthrax was confirmed in Tengwe. Consumption of under-cooked meat was associated with gastrointestinal anthrax. The timely one health response resulted in excellent outcomes. Using one health approach in managing zoonotic threats is encouraged.

An evaluation of the isoniazid preventive therapy program performance for under-fives in Kwekwe City, January 2019 - December 2020: a descriptive cross-sectional study.

Childhood tuberculosis (TB) is underserved in resource-constrained endemic areas. Zimbabwe National Tuberculosis Program recommends tuberculosis prevention treatment for children aged <5 years who are close contacts of smear-positive TB cases. The Isoniazid Preventive Therapy (IPT) program performance had never been evaluated since its inception in 2010. We therefore, assessed the IPT program's inputs, processes, outputs, and outcomes. We conducted a process evaluation using the logic model in Kwekwe City. We recruited twenty-seven health care workers from all the five municipal health facilities. Smear-positive guardians of under 5 children, health care workers, and registers were the study population. Data were collected using a questionnaire and checklists and presented as frequencies and proportions. The IPT program met requirements in provision of guidelines (10/10), screening tools (15/15) and on-the-job trainings done in all five health facilities. Isoniazid tablets supply and quarterly budgeting did not meet meeting program requirements. Fifty-nine out of 231 (25.5%) children contacts of sputum-positive TB patients were screened. Fifty-one of the 59 (86.4%) children were initiated on IPT, 42/51 (82.4%) completed the course, one developed TB, 3/51 were still on treatment and 5/51 were lost to follow up. No dropouts and deaths were recorded. Unavailability of drugs was a barrier to the IPT and negatively impacts the TB elimination program. Contact screening was the bottleneck in the successful implementation of the program. Adequate staff and provision of drugs might improve the program. We recommended the recruitment of more healthcare workers and the budget for the program.

Evaluation of the measles case-based surveillance system in Kwekwe city, 2017-2020: a descriptive cross-sectional study.

Introduction: in 2011, WHO African region set a target for elimination of measles by 2020. During period 2017-2020, Kwekwe city, with an estimated population of 117,116, detected one case of suspected measles. This was against a target of 2 cases per year. We evaluated the system to establish why it was failing to detect at least 2 cases per year. Methods: we conducted a descriptive cross-sectional study using the Centre for Disease Control (CDC) Updated Guidelines. Nineteen health facilities were selected and fifty-seven health workers were randomly recruited. An interviewer-administered questionnaire and checklists were used to collect data. We generated frequencies, proportions, and means. Results: the mean years in service was 22.8 years (SD=12.6). Thirty (52.6%) respondents had fair knowledge. Fourteen (73.7%) of the nineteen respondents who had ever completed case investigation forms took between 10-20 minutes to complete. Only two (10.5%) of the nineteen facilities had case investigation forms. The majority of the respondents 54 (93%) were willing to continue participating in the measles Community Base Surveillance System (CBSS). None of the health facilities had used the system to inform decision-making. Reasons highlighted for poor suspected measles case detection included lack of health worker training 28/57 (49.1%). Conclusion: despite the high age in service, knowledge of the surveillance system was mostly fair. The system was found to be simple, not stable and not useful. The main reason for the system failure was lack of health worker training. We recommend retraining on Integrated Disease Surveillance and Response (IDSR) and case investigation forms distribution.

An evaluation of the notifiable disease surveillance system in Chegutu District, Zimbabwe, 2020: a cross-sectional study.

Introduction: in 2018-2019 Chegutu District had one notification form Tally 1 (T1) that was completed instead of seven for detected notifiable diseases. Different figures of cholera were reported through weekly rapid disease notification system with 106 patients and Notifiable Diseases Surveillance System (NDSS) with 111 patients, causing data discrepancy. We evaluated the NDSS to determine reasons for underperformance and data discrepancy. Methods: we conducted descriptive cross-sectional study using updated centres for disease control and prevention guidelines for surveillance system evaluation. We recruited forty-six health workers. Interviewer-administered questionnaires and checklists were used to collect data on reasons for underperformance, reasons for data discrepancy, knowledge of NDSS, surveillance system attributes and usefulness. Epi InfoTM7 generated frequencies, proportions, and means. Likert scale was used to assess health worker knowledge. Results: of the forty-six health workers, 34 (78%) had fair knowledge of NDSS. The reason for system underperformance was lack of training in NDSS 42 (91%). Data discrepancy was attributed to typographical mistakes made during data entry on WhatsApp platform 32 (70%). Eighty per cent (37) were willing to complete T1 forms. Six participants who were timed took ten minutes to complete T1 forms. Among 17 health facilities, only three had fifteen T1 forms that were adequate to notify first five cases in an outbreak. Notifiable diseases surveillance system data was used for planning health education 28 (68%). Conclusion: the NDSS was unstable due to health workers' inadequate knowledge and unavailability of T1 forms. Notifiable diseases surveillance system was found to be simple, acceptable, and useful. We recommended NDSS training of health workers.

The epidemiology of drug-resistant tuberculosis in Bulawayo and Matabeleland South provinces, Zimbabwe 2017.

Objective: To investigate determinants of drug resistance and treatment outcomes among patients with drug-resistant tuberculosis (DR-TB). Design: This was a cross-sectional study on patients diagnosed with DR-TB in Bulawayo and Matabeleland South provinces, 2015. Results: A total of 129 participants were identified. DR-TB patients were 3.4 times more likely to have been treated previously for sensitive TB (95% confidence interval 1.3-9.2). Approximately 88.5% of DR-TB patients were diagnosed before completing the sensitive TB course and another 82.1% developed DR-TB within 6 months of completing sensitive TB treatment. The likelihood diminished with increasing time interval, becoming less likely at >12 months post-treatment. Most DR-TB patients (87.5%) were likely to have resided outside Zimbabwe and to have fallen ill there (85.2%). Overall, hearing loss was the most prevalent (70%) medication side effect experienced. Unfavourable interim treatment outcomes were high for patients <6 months on treatment (prevalence odds ratio 2.7, 95% CI 1.2-6.1), becoming 44% less likely after 18 months (95% CI 1.2-11.4). Conclusions: The majority of DR-TB patients were diagnosed during sensitive TB treatment, suggesting missed DR-TB diagnosis or inadequate treatment. Delays in starting effective TB regimens negatively affect treatment outcomes. Drug sensitivity testing at diagnosis, patient monitoring, and enhanced adherence counselling are recommended.

Risk factors for contracting watery diarrhoea in Mzilikazi, Bulawayo City, Zimbabwe, 2020: a case control study.

Introduction: Mzilikazi clinic had an upsurge of diarrhoea cases with 41 cases from the 28th to the 30th of September 2020, against a threshold of 11. We therefore, investigated the risk factors associated with this outbreak to recommend prevention and control measures. Methods: we conducted a 1:1 unmatched case-control study. A case was any person who suffered from diarrhoea, and was resident in the clinic´s catchment since the 21st of September 2020. Demographic data, knowledge and practices related to diarrhoea were collected using a standard questionnaire for both cases and controls. Environmental assessment, water quality and stool testing was also done. We conducted univariate and multivariate analysis at 95% confidence interval, to determine factors independently associated with contracting diarrhoea. Results: the median age was 30 years (Q1=12, Q3=46) for cases and 30 years (Q1=22, Q3=48) for controls. The dominant gender was female for cases and male for controls. The independent risk factors were: drinking borehole water [adjusted Odds Ratio (aOR)=2.66; 95%CI=(1.41-5.00)], storing water in open container [aOR=2.76; 95%CI=(1.38-5.53)] and being under-five years old [aOR=5.73; 95%CI=(2.06-15.89)]. Boiling drinking water [aOR=0.39; 95%CI=(0.20-0.75)] was protective. Coliforms were detected from boreholes and stored water samples, and Shigella flexneri was isolated from 2 of the 13 stool specimens collected. Residents accessed water from decommissioned boreholes due to severe municipal water rationing. Conclusion: being under-five years old, drinking borehole water and storing water in open containers were independent risk factors. Health education on home water treatment, distribution of water storage containers, and Aquatabs was done.

An evaluation of childhood tuberculosis program in Chegutu District, Zimbabwe, 2020: a descriptive cross-sectional study.

BACKGROUND: Childhood tuberculosis (TB) is a major global public health concern contributing to significant child morbidity and mortality. A records review of the TB notification for Chegutu District Health Information System 2 (DHIS2) showed a low childhood TB case detection rate. For 2018 and 2019, childhood TB notifications were 4% and 7% respectively against the annual national childhood 12% case detection rate. We evaluated the performance of the childhood TB program in Chegutu. METHODS: We conducted a descriptive cross-sectional study. Sixty-six health workers (HW) participated in the study. Interviewer-administered questionnaires and checklists were used to collect data on reasons for low TB case detection, HW childhood TB knowledge, program inputs, processes, and outputs. Strengths, Weaknesses, Opportunities and Threats analysis was used to assess the childhood TB processes. We analyzed the data using Epi Info 7™ to generate frequencies, proportions and means. A Likert scale was used to assess health worker knowledge. RESULTS: The majority 51/66(77%) of HW were nurses and 51/66(67%) of respondents were females. Reasons for the low childhood TB case detection were lack of HW confidence in collecting gastric aspirates 55/66(83%) and HW's negative attitudes towards gastric aspirate collection 23/66(35%). HW 24/66 (37%) had a fair knowledge of childhood TB notification. The district had only one functional X-ray machine for 34 health facilities. Only 6/18 motorcycles were functional with inadequate fuel supply. No desk guide for the management of TB in children for HW (2018) was available in 34 health facilities. Ethambutol 400 mg was out of stock and adult 800 mg tablets were used. Funds allocated for motor vehicle and motorcycles service ($1612USD/year) were inadequate. The district failed to perform planned quarterly TB review meetings, contact tracing and childhood TB training due to funding and COVID-19 lockdown restrictions. CONCLUSION: The childhood TB program failed to meet its targets due to inadequate inputs, HW suboptimal knowledge and COVID-19 lockdown measures. Case detection and notification can be improved through on-job training, mentorship, support and supervision and adequate resources.

Factors associated with a malaria outbreak at Tongogara refugee camp in Chipinge District, Zimbabwe, 2021: a case-control study.

BACKGROUND: Malaria is a leading cause of morbidity and mortality among forcibly displaced populations, including refugees, approximately two-thirds of whom reside in malaria endemic regions. Data from the rapid disease notification system (RDNS) reports for Manicaland Province in Zimbabwe showed that despite implementation of malaria control initiatives, there was an increase in number of malaria cases above action thresholds at Tongogara refugee camp in Chipinge district during weeks 12-14 of 2021. An investigation that described the outbreak by person, place and time was conducted. Malaria emergency preparedness, response, and appropriateness of case management were assessed. The factors associated with contracting malaria were determined to enable the formulation of appropriate interventions, establish control, and prevent future malaria outbreaks among this vulnerable population. METHODS: A 1:1 unmatched case-control study involving 80 cases and 80 controls was conducted using interviewer-administered questionnaires at household level. Data was entered into Epi Data version 3.1 and quantitative analysis was done using Epi Info™ version 7.2.2.6 to generate medians, proportions, odds ratios and their 95% confidence intervals. RESULTS: Malaria cases were distributed throughout the 10 residential sections within Tongogara refugee camp, the majority being from section 7, 28 (35%). Despite constituting 11% of the total population, Mozambican nationals accounted for 36 (45%) cases. Males constituted 47 (59%) among cases which was comparable to controls 43 (54%), p = 0.524. The median age for cases was 15 years [Interquartile range (IQR), 9-26] comparable to controls, which was 17 years (IQR, 10-30) (p = 0.755). Several natural and man-made potential vector breeding sites were observed around the camp. Risk factors associated with contracting malaria were engaging in outdoor activities at night [AOR = 2.74 (95% CI 1.04-7.22), wearing clothes that do not cover the whole body during outdoor activities [AOR 4.26 (95% CI, 1.43-12.68)], while residing in a refugee housing unit reduced the risk of contracting malaria [AOR = 0.18 (CI, 0.06-0.55)]. CONCLUSIONS: The malaria outbreak at Tongogara refugee camp reemphasizes the role of behavioural factors in malaria transmission. Intensified health education to address human behaviours that expose residents to malaria, habitat modification, and larviciding to eliminate mosquito breeding sites were recommended.

Trends of stillbirths in Harare City, Zimbabwe, 2015-2019: a secondary data analysis.

Introduction: in Zimbabwe, perinatal mortality is a major public health problem. Harare City data showed increase in stillbirth rate trend from 4/1000 live births in 2014 to 6/1000 live births in 2018, failing to meet the country's target of reducing stillbirth rate by 40%. We analysed the characteristics of stillbirths from 2015 to 2019 in Harare City. Methods: we conducted a retrospective analytical cross-sectional study using secondary data from Harare City Health Department's 12 baby-delivery polyclinics. Fourteen key informants were interviewed to verify information obtained. Using Epi-info, descriptive summaries and graphs were generated and bivariate and multivariate logistic regression was conducted. Statistical significance was considered at a p-value <0.05. Results: a total of 700(74.9%) perinatal death notification records were reviewed. The majority were macerated stillbirths 418(59.7%) followed by fresh stillbirths 189(27.0%). The median age for women who had fresh stillbirths was 26 years (Q1=22; Q2=32). Preterm delivery (aOR= 2.15; 95%CI 1.81- 3.89; p<0.01), having delivered by breech presentation (aOR= 3.32; 95%CI 1.72-6.41; p=<0.01), and being HIV positive (aOR= 1.69; 95%CI 1.02-2.79; p=0.04) were associated with preterm delivery. Conclusion: stillbirths in Harare City were increasing and were due to preventable causes. The younger maternal age group was most affected hence preventive activities should focus on them. Improving the quality of antenatal care, delivery, and new-born care can help reduce stillbirths and early neonatal death.

Evaluation of the weekly disease surveillance system for epidemic-prone diseases in Makonde District, Zimbabwe 2020: a descriptive cross-sectional study.

Introduction: the weekly disease surveillance system (WDSS) is a tool used to provide an early warning of potential public health threats in Zimbabwe. In 2020, Makonde District failed to detect an anthrax outbreak at one of its facilities, this untimely and poor response of the district increased morbidity. We evaluated the weekly disease surveillance system to determine reasons for missing outbreaks and determine the usefulness of the system in the detection of outbreaks. Methods: we conducted descriptive cross-sectional study using updated Centres for Disease Control and Prevention guidelines for surveillance system evaluation. We recruited 46 health workers. A structured pretested interviewer-administered questionnaire was used to collect data on reasons for missing outbreaks, knowledge, usefulness and surveillance system attributes. Data were cleaned and bivariate analysis was conducted. Results: health workers found the system simple (85%), acceptable (75%) and flexible (60%). However, we found only 5 (11%) health workers could correctly describe the surveillance system, only 2 (3%) were trained in disease surveillance, only 31 (65%) sent data on time, 57% of clinics had stock outs of forms, 60% of forms had entries with 100% of the data filled out and 22 (46%) of health workers analysed the data gathered and used it in meetings. Conclusion: the surveillance system was simple, flexible, acceptable, but unstable, untimely and not useful. There was poor knowledge on the surveillance system, health workers were not trained on disease surveillance, and quality of data was poor. Health workers should be trained in surveillance and data validation and adequate reporting tools provided.

Evaluation of intensified provider initiated testing and counselling program in Harare City, 2017-2018.

BACKGROUND: Knowledge of HIV status remains a challenge despite implementation of various testing strategies including provider-initiated HIV testing (PITC). Harare City intensified provider-initiated HIV testing by targeting testing all eligible clients visiting facilities to achieve the UNAIDS first 95. This study aimed at evaluating the intervention to improve its effectiveness and inform programming decisions for universal access to HIV testing. METHODS: A descriptive cross-sectional study was conducted in Harare from April to June 2019. Evaluation of the intervention was conducted using the logic model approach to assess the inputs, processes and outputs. Health workers were interviewed using an interviewer administered questionnaire. Exit interviews were conducted for eligible clients > 18 years who refused to be tested. A checklist was used to assess the inputs used and a desk review of HIV screening and testing records was done. RESULTS: A total of (n-45) health care workers and (n = 70) clients were interviewed with a response rate of (92%) and (84%) respectively. The median age for clients was 31(Q1 = 24: Q3 = 38) and median years in service for health workers was 2 (Q1 = 1;Q3 = 26). Of the 133,899 clients who were eligible for testing after screening, 98,587 (74%) accepted the test leaving a gap of 35,312 (26%). However, 21/45 (47%) of health workers indicated high workload in the morning as the major reason for the leakage. In addition, 25/70 (36%) of the clients indicated long waiting time as the reason for opting out of HIV testing. CONCLUSION AND RECOMMENDATION: HIV testing coverage for eligible clients was not optimal, 26% opted out. We recommend strengthening of health facility systems such as review of patient flow, re-allocation of staff during busy HIV testing time and scaling up the use of HIV self-test kits for clients concerned with waiting time to improve HIV testing coverage.

Trends in antimicrobial resistance of bacterial pathogens in Harare, Zimbabwe, 2012-2017: a secondary dataset analysis.

BACKGROUND: Antimicrobial resistance is one of the most serious public health threats of the twenty-first century. The implementation of AMR surveillance in Zimbabwe is limited. However, data from a private laboratory in Harare revealed increasing resistance rates to common antibiotics like ampicillin (i.e., from 73.9% in 2011 to 74.6% in 2015). The increasing resistance rates indicate that Zimbabwe is affected by AMR. This study was done to determine the magnitude of AMR in Harare and determine the trends of AMR to first-line and to last-resort antibiotics and make recommendations to mitigate the problem. METHODS: A retrospective record review of data collected from the microbiology department at a private laboratory between January 2012 and December 2017 was done. The outcome of interest was the antibiotic susceptibility of bacterial isolates. Microsoft Excel 2016 was used to plot trends from 2012 to 2017 and Epi Info™7 was used for statistical analysis. RESULTS: A total of 23,432 isolates, of 12 medically important bacteria were analysed. Forty-three percent of the isolates were from urines, 36.7% were from pus swabs and 7% were from blood. The most common pathogen was Escherichia coli (43.2%), followed by Staphylococcus aureus (15.8%) and the least common was Neisseria gonorrhoea (0.2%). Resistance was highest to ampicillin followed by penicillin, both ranging between 70 and 100% over the six years. Statistically significant increases in resistance to commonly used antibiotics were observed in amoxicillin-resistant E. coli and Streptococcus pneumonia and third generation cephalosporin-resistant E. coli. There was an increase in resistance to last-line antibiotics i.e., fluoroquinolone-resistant Salmonella spp. and carbapenem-resistant Pseudomonas aeruginosa and Acinetobacter baumannii. However, methicillin-resistant S. aureus showed a decreasing trend. CONCLUSIONS: There is a high burden of drug resistance to common antibiotics in Harare and an emergence of resistance to last-line antibiotics.

Field-based evaluation of malaria outbreak detection and response in Mudzi and Goromonzi districts, Zimbabwe - 2017.

National-level evaluations may fail to identify capacity improvements for detecting and responding to outbreaks which begin and are first detected at the local level. In response to this issue, we conducted a field-based assessment of the malaria outbreak surveillance system in Mashonaland East, Zimbabwe. We visited eleven clinics in Mudzi and Goromonzi districts. Twenty-one interviews were conducted with key informants from the provincial (n = 2), district (n = 7), and clinic (n = 12) levels. Interviews focused on surveillance system activities, preparedness, data quality, timeliness, stability, and usefulness. Main themes were captured utilising standard qualitative data analysis techniques. While the surveillance system detects malaria outbreaks at all levels, we identified several gaps. Clinics experience barriers to timely and reliable reporting of outbreaks to the district level and staff cross-training. Stability of resources, including transportation (33% of informants, n = 7) and staff capacity (48% of informants, n = 10), presented barriers. Strengthening these surveillance barriers may improve staff readiness to detect malaria outbreaks, resulting in timelier outbreak response and a reduction in malaria outbreaks, cases, and deaths. By focusing at the local level, our assessment approach provides a framework for identifying and addressing gaps that may be overlooked when utilising tools that evaluate surveillance capacity at the national level.

Utilization and outcomes of cervical cancer screening services in Harare City, 2012-2016: a secondary data analysis.

BACKGROUND: Visual inspection with acetic acid and cervicography (VIAC) is a method used to screen for cervical cancer. VIAC can be used as part of a "see and treat" strategy. Nine Harare city council health facilities offer VIAC free of charge with the aim of reducing morbidity and mortality from cervical cancer. Between 2014 and 2016, the number of women utilising VIAC dropped by 35%. We analysed records of clients who utilise VIAC at Harare city health facilities to characterise women accessing VIAC and their outcomes to make recommendations for improving the services. METHODS: We conducted a descriptive cross-sectional study using data collected for the Harare city VIAC program. We analysed all records of clients who utilised VIAC services at nine Harare city health facilities from 1 May 2012 to 31 December 2016. RESULTS: We analysed 46,217 records, the median age of the clients was 34 years [Q1 = 27: Q3 = 42]. Of the 46,217 clients screened, 3001 (6.5%) were VIAC positive, and 512 (1.1%) had suspicious of cancer lesions. The prevalence of VIAC positive ranged from 58 to 74 per 1000-screened clients over the 5 years. The prevalence of suspected cancer ranged from 9 to 14 per 1000-screened clients, and there was a general decrease in the prevalence between 2012 and 2016. Of the 3513 clients with VIAC positive or had suspicious of cancer lesions, 2090 (74.1%) did not receive treatment at the site where the screening took place. CONCLUSION: The majority of women who are accessing VIAC services in Harare are middle-aged, multiparous and married women. There is a treatment gap at most of the VIAC centres such that clients are referred to other centres for management. The objective of "see and treat" is not being realised.

Evaluation of the Maternal Death Surveillance and response system in Hwange District, Zimbabwe, 2017.

BACKGROUND: Maternal Death Surveillance and Response (MDSR) system was established to provide information that effectively guides actions to eliminate preventable maternal mortality. In 2016, Hwange district sent six maternal death notification forms (MDNF) to the province without maternal death audit reports. Timeliness of MDNF reaching the province is a challenge. Two MDNF for deaths that occurred in February and May 2016 only reached the provincial office in September 2016 meaning the MDNF were seven and four months late respectively. We evaluated the MDSR system in Hwange district. METHODS: A descriptive cross-sectional study was conducted. Health workers in the sampled facilities were interviewed using questionnaires. Resource availability was assessed through checklists. Epi Info 7 was used to calculate frequencies, means and proportions. RESULTS: We recruited 36 respondents from 11 facilities, 72.2% were females. Inadequate health worker knowledge, lack of induction on MDSR, unavailability of guidelines and notification forms and lack of knowledge on the flow of information in the system were reasons for late notification of maternal deaths. Workers trained in MDSR were 83.8%. Only 36.1% of respondents had completed an MDNF before. Respondents who used MDSR data at their level were 91.7%, and they reported that MDSR system was useful. Responsibility to complete the MDNF was placed on health workers. Maternal death case definitions were available in 2/11 facilities, 4/11 facilities had guidelines for maternal death audits. It costs $60.78 to notify a maternal death. CONCLUSION: Reasons for late notification of maternal deaths were inadequate knowledge, lack of induction, unavailability of guidelines and notification forms at facilities. The MDSR system is useful, acceptable, flexible, unstable, reliable but not simple. Maternal case definitions and maternal death audit guidelines should be distributed to all facilities. Training of all health workers involved in MDSR is recommended.
