Evaluation of interventions to improve timely hepatitis B birth dose vaccination among infants and maternal tetanus vaccination among pregnant women in Nigeria.

BACKGROUND: Nigeria has the largest number of children infected with hepatitis B virus (HBV) globally and has not yet achieved maternal and neonatal tetanus elimination. In Nigeria, maternal tetanus diphtheria (Td) vaccination is part of antenatal care and hepatitis B birth dose (HepB-BD) vaccination for newborns has been offered since 2004. We implemented interventions targeting healthcare workers (HCWs), community volunteers, and pregnant women attending antenatal care with the goal of improving timely (within 24 hours) HepB-BD vaccination among newborns and Td vaccination coverage among pregnant women. METHODS: We selected 80 public health facilities in Adamawa and Enugu states, with half intervention facilities and half control. Interventions included HCW and community volunteer trainings, engagement of pregnant women, and supportive supervision at facilities. Timely HepB-BD coverage and at least two doses of Td (Td2+) coverage were assessed at baseline before project implementation (January-June 2021) and at endline, one year after implementation (January-June 2022). We held focus group discussions at intervention facilities to discuss intervention strengths, challenges, and improvement opportunities. RESULTS: Compared to baseline, endline median vaccination coverage increased for timely HepB-BD from 2.6% to 61.8% and for Td2+ from 20.4% to 26.9% in intervention facilities (p < 0.05). In comparison, at endline in control facilities median vaccination coverage for timely HepB-BD was 7.9% (p < 0.0001) and Td2+ coverage was 22.2% (p = 0.14). Focus group discussions revealed that HCWs felt empowered to administer vaccination due to increased knowledge on hepatitis B and tetanus, pregnant women had increased knowledge that led to improved health seeking behaviors including Td vaccination, and transportation support was needed to reach those in far communities. CONCLUSION: Targeted interventions significantly increased timely HepB-BD and Td vaccination rates in intervention facilities. Continued support of these successful interventions could help Nigeria reach hepatitis B and maternal and neonatal tetanus elimination goals.

Improving health information system for malaria program management: Malaria Frontline Project lessons learned from Kano and Zamfara States, Nigeria, 2016-2019.

The U.S. Centers for Disease Control and Prevention in collaboration with the National Malaria Elimination Program and the African Field Epidemiology Network established the Malaria Frontline Project to provide innovative approaches to improve the malaria program implementation in Kano and Zamfara States, Nigeria. Innovative approaches such as malaria bulletin, malaria monitoring wall chart, conduct of ward level data validation meetings and malaria dashboard have helped improve the use of data for decision making at all levels. Innovative approaches deployed during the project implementation facilitated data analysis and a better understanding of malaria program performance and data utilization for decision making at all levels. These innovative approaches may improve malaria control program performance in Nigeria and other resource limited countries.

Environmental and psychosocial predictors of cervical cancer screening among women in Gwagwalada Area Council, Abuja, North Central, Nigeria.

Cervical cancer (CC) is the second leading cause of cancer morbidity and mortality among Nigerian women. Although screening is a cost-effective strategy for reducing its burden, uptake remains sub-optimal. A descriptive cross-sectional study was conducted among 514 sexually active women aged ≥25 years in Gwagwalada Area Council, Abuja, Nigeria using a semi-structured interviewer administered questionnaire. Mean age of respondents was 38.4±11.6years. 246(46.9%) had good knowledge of CC screening while 268(51.2%) had poor knowledge. Religion (aOR:1.8 [95% CI: 1.1 - 3.1]), location (aOR:1.2 [95% CI: 1.2 - 3.4) and number of children (aOR:2.3 [95% CI: 1.3 - 3.9]) were predictors for screening. Poor access routes to health facilities (aOR:0.5 [95% CI: 0.2 - 0.9]), high cost of screening (aOR:0.4 [95% CI: 0.2 - 0.9]), unaware of screening centers (aOR:0.4 [95% CI: 0.2 - 0.9]) and long waiting hours (aOR:0.5 [95% CI: 0.2 - 0.9) were identified environmental predictors. Fear of positive diagnosis/stigma (aOR:0.3 [95% CI: 0.1 - 0.9]), unacceptable touch (aOR:0.2 [95% CI: 0.1 - 0.8), deficiency in awareness programs (aOR:0.3 [95% CI: 0.2 - 0.7]), and not aware of appropriate screening age (aOR:0.1 [95% CI: 0.1 - 0.4]) were identified psychosocial predictors. This study highlights the need to intensify enlightenment programs, subsidize screening services, and encourage community screening.

Barriers and facilitators to hepatitis B birth dose vaccination: Perspectives from healthcare providers and pregnant women accessing antenatal care in Nigeria.

Nigeria is estimated to have the largest number of children worldwide, living with chronic hepatitis B virus (HBV) infection, the leading cause of liver cancer. Up to 90% of children infected at birth develop chronic HBV infection. A birth dose of the hepatitis B vaccine (HepB-BD) followed by at least two additional vaccine doses is recommended for prevention. This study assessed barriers and facilitators of HepB-BD administration and uptake, using structured interviews with healthcare providers and pregnant women in Adamawa and Enugu States, Nigeria. The Consolidated Framework for Implementation Sciences Research (CFIR) guided data collection and analysis. We interviewed 87 key informants (40 healthcare providers and 47 pregnant women) and created a codebook for data analysis. Codes were developed by reviewing the literature and reading a subsample of queries line-by-line. The overarching themes identified as barriers among healthcare providers were: the lack of hepatitis B knowledge, limited availability of HepB-BD to vaccination days only, misconceptions about HepB-BD vaccination, challenges in health facility staffing capacity, costs associated with vaccine transportation, and concerns related to vaccine wastage. Facilitators of timely HepB-BD vaccination included: vaccine availability, storage, and hospital births occurring during immunization days. Overarching themes identified as barriers among pregnant women were lack of hepatitis B knowledge, limited understanding of HepB-BD importance, and limited access to vaccines for births occurring outside of a health facility. Facilitators were high vaccine acceptance and willingness for their infants to receive HepB-BD if recommended by providers. Findings indicate the need for enhanced HepB-BD vaccination training for HCWs, educating pregnant women on HBV and the importance of timely HepB-BD, updating policies to enable HepB-BD administration within 24 hours of birth, expanding HepB-BD availability in public and private hospital maternity wards for all facility births, and outreach activities to reach home births.

Malaria Frontline Project: strategic approaches to improve malaria control program leveraging experiences from Kano and Zamfara States, Nigeria, 2016-2019.

BACKGROUND: The Malaria Frontline Project (MFP) supported the National Malaria Elimination Program for effective program implementation in the high malaria-burden states of Kano and Zamfara adapting the National Stop Transmission of Polio (NSTOP) program elimination strategies. PROJECT IMPLEMENTATION: The MFP was implemented in 34 LGAs in the two states (20 out of 44 in Kano and all 14 in Zamfara). MFP developed training materials and job aids tailored to expected service delivery for primary and district health facilities and strengthened supportive supervision. Pre- and post-implementation assessments of intervention impacts were conducted in both states. RESULTS: A total of 158 (Kano:83; Zamfara:75) and 180 (Kano:100; Zamfara:80) healthcare workers (HCWs), were interviewed for pre-and post-implementation assessments, respectively. The proportions of HCWs with correct knowledge on diagnostic criteria were Kano: 97.5% to 92.0% and Zamfara: 94.7% to 98.8%; and knowledge of recommended first line treatment of uncomplicated malaria were Kano: 68.7% to 76.0% and Zamfara: 69.3% to 65.0%. The proportion of HCWs who adhered to national guidelines for malaria diagnosis and treatment increased in both states (Kano: 36.1% to 73.0%; Zamfara: 39.2% to 67.5%) and HCW knowledge to confirm malaria diagnosis slightly decreased in Kano State but increased in Zamfara State (Kano: 97.5% to 92.0%; Zamfara: 94.8% to 98.8%). HCWs knowledge of correct IPTp drug increased in both states (Kano: 81.9% to 94.0%; Zamfara: 85.3% to 97.5%). CONCLUSION: MFP was successfully implemented using tailored training materials, job aids, supportive supervision, and data use. The project strategy can likely be adapted to improve the effectiveness of malaria program implementation in other Nigerian states, and other malaria endemic countries.

What do malaria program officers want to learn? A survey of perspectives on a proposed malaria short course in Nigeria.

BACKGROUND: In disease control, the program officers are vital to the successful implementation of control strategies. However, poor knowledge of the disease and its control, staff attrition, and lack of intentional training for new staff can lead to under-performance and ineffectiveness of interventions. Thus, the Nigeria Field Epidemiology and Laboratory Training Program, in collaboration with National Malaria Elimination Program, planned a malaria short course (MSC) to strengthen the capacity of current program managers and incoming staff. To guide the development of the curriculum for the MSC, we conducted a needs assessment survey to ascertain the perceived usefulness of the MSC, the priority rating of MSC thematic domains and associated factors. METHODS: Overall, 384 purposively selected respondents across ten states and the Federal Capital Territory in Nigeria were interviewed. These comprised malaria and non-malaria control program staff at state, local government area (LGA) and ward levels. We administered a structured questionnaire to elicit information on socio-demographics, training needs, priority malaria thematic domains, perceived course usefulness and willingness of ministries/organizations to release staff to attend the MSC. Data were analyzed using descriptive and inferential statistics at p<0.05. RESULTS: Mean age was 43.9 (standard deviation: 7.6 years), 172 (44.8%) were females. Of the 384 respondents, 181 (47.1%), 144 (37.5%) and 59 (15.4%) were at the ward, LGA and state levels, respectively. Seventy-two (18.8%) had never worked in malaria control program. Majority (98.7%, n = 379) reported the need for further training, 382 (99.5%) opined that the course would be useful, and all affirmed their employers' willingness towards their participation at the training. Respondents rated high the domains of basic malariology, malaria treatment, malaria prevention, surveillance/data management, use of computers, leadership skills, program management and basic statistics. Predictors of malaria topical domains' high rating were gender (odds ratio (OR) = 6.77; 95% CI:3.55-12.93) and educational qualifications (OR = 0.48; 95% CI:0.26-0.89). CONCLUSIONS: A malaria short course is a necessity and appropriate for program officers at different levels of health administration in Nigeria to achieve malaria elimination, taking into consideration the challenges of human resource retention. The outcome of this study should inform the curriculum and the delivery of the MSC.

Malaria frontline project: pre-intervention Malaria baseline assessment in Kano and Zamfara States, August 2016.

Introduction: In 2016, the Centers for Disease Control and Prevention and the Government of Nigeria initiated the Malaria Frontline Project in Kano and Zamfara States. The project goal is to improve the quality and coverages of malaria interventions adapting polio program strategy. We conducted a baseline assessment of malaria interventions. Methods: Twenty-four primary health centers per State were selected using probability sampling. Health workers (HW) were purposively sampled to assess their knowledge of national malaria control guidelines. Clients were selected for exit interview to assess health workers´ adherence to the national guidelines. WHO cluster methodology was used to survey heads of household and women of reproductive age on knowledge of malaria prevention, Long Lasting Insecticidal Net (LLIN) ownership and use. Results: Of the 158 HW interviewed, 94.3% knew the correct criteria for malaria diagnosis, 86.1% reported using artemisinin-based therapy to treat uncomplicated malaria. About 45% of HW reported prescribing artemisinin-based combination therapy (ACT) for uncomplicated malaria in first trimester of pregnancy and 39% prescribed quinine. Only 73.9% of fever cases were referred to laboratory as recommended by the national guideline. Households with one LLIN per 2 persons (Kano: 27.1%; Zamfara: 30.0%), LLIN use (Kano: 70.8%; Zamfara: 81.6%) and IPTp1 (Kano: 38.6%; Zamfara: 33.3%). Conclusion: most clinicians have knowledge of national guidelines, but fewer adhere to guidelines in practice. Population LLIN ownership, LLIN use among pregnant women and IPTp are lower than the national targets of 58%, 83% and 75% respectively for 2016. We recommend improving health workers´ technical capacity and adherence to national malaria guidelines.

Enhancing acute flaccid paralysis surveillance through the use of pictorial surveillance reminder cards during supplementary immunization activities, December 2014: a survey in Jigawa State, Nigeria.

Introduction: Acute flaccid paralysis (AFP) pictorial surveillance reminder cards (AFP cards) could aid AFP case identification during supplementary immunization activities (SIAs). We assessed the availability and utilization of AFP cards among vaccination teams during the December 2014 polio SIAs in Jigawa State, Nigeria. Methods: We conducted a cross-sectional survey of a convenience sample of 95 vaccination team supervisors. We used a semi-structured interviewer-administered questionnaire to collect information on socio-demographics, knowledge of AFP cases, availability and utilization of the AFP cards for case identification and investigation and non-compliance resolution by vaccination teams. Univariate and bivariate analyses were performed using Epi Info version 3.5.1. Results: Of the 95 supervisors interviewed, 86 (91%) reported that vaccinators properly displayed the AFP cards, 90 (95%) reported use of cards for AFP case identification, 88 (93%) reported use of cards to resolve non-compliance with polio vaccination and 77 (81%) reported use of cards to ask caregivers six key questions to prevent missed children. Fifty-eight (61%) supervisors knew the AFP case definition. A total of 21 possible AFP cases were identified by vaccination team members with the aid of the cards, of which 17 (81%) were referred to the nearest health facility. Conclusion: The survey demonstrated usefulness of reminder cards for identification and follow-up of AFP cases. Based on these findings, use of AFP cards was implemented in all Nigerian States and similar cards were developed and implemented for measles surveillance during SIAs.

Assessment of health service delivery parameters in Kano and Zamfara States, Nigeria.

BACKGROUND: In 2013, the Nigeria Federal Ministry of Health established a Master Health Facility List (MHFL) as recommended by WHO. Since then, some health facilities (HFs) have ceased functioning and new facilities were established. We updated the MHFL and assessed service delivery parameters in the Malaria Frontline Project implementing areas in Kano and Zamfara States. METHODS: We assessed all HFs in each of the 34 project local government areas (LGAs) between July and September 2017. Project staff administered a semi-structured questionnaire developed for this assessment to heads of HFs about the type of facility, category and number of staff working at the facility and to record geo-coordinates of facility. RESULTS: In the Kano State project area, 726 HFs were identified and geo-located: 31 were new facilities, 608 (84%), 116 (16%) and two (0.3%) were Primary Health Care (PHC), secondary and tertiary facilities respectively. Using the national definition, there were 710 (98%) functional facilities and 644 (91%) of these reported to the national health information platform, District Health Information System, version 2 (DHIS2). The Zamfara project area had 739 HFs: eight were new, 715 (97%), 22 (3.0%) and two (0.2%) PHCs, secondary and tertiary facilities respectively. There were 695 (94%) functional facilities with 656 (94%) of these reporting to DHIS2. Using national criteria for primary health care designation, only 95 (9%) of all PHCs in the two States met the minimum human resource requirements. CONCLUSION: Most HFs were functional and reported to DHIS2. A comprehensive MHFL having all the important parameters that should be established and updated regularly by authorities to make it more useful for health services administration and management. Most functional facilities are understaffed.

Is the malaria short course for program managers, a priority for malaria control effort in Nigeria? Evidence from a qualitative study.

BACKGROUND: A Malaria Short Course (MSC) was conceptualized to build the capacity of program managers for malaria control due to the lack of a single comprehensive broad-based programmatic training in Nigeria. Prior to its implementation, a needs assessment was conducted based on the perspectives of stakeholders to plan and develop the curriculum. METHODS: This was an exploratory qualitative study. Fifty-six purposively selected stakeholders at local, state and national levels were interviewed. Opinions on the need for training, its perceived impact, priority focus, likelihood of participation, sustainability of and planned support for the MSC were explored using a pretested researcher-designed interview guide. Interviews were audiotape recorded, and the transcripts were subjected to thematic content analysis. RESULTS: Participants included Directors of Primary Health Care (50%), State Malaria Program Officers (8.9%), State Directors of Public Health Services (7.1%) and Roll Back Malaria Officers (5.4%). Participants' mean number of years of experience in their current positions was 6.2 (SD 4.7) years. The dominant view was "malaria remains a problem in Nigeria, exacerbated by poor funding, knowledge deficit, lack of training opportunities for program managers and prioritized training budget". A common viewpoint was "to achieve the malaria policy goals, MSC should focus on improving program managers' knowledge of the disease, novel interventions, data audit and use of data for decision making, supportive supervision as well as leadership and management skills. The prioritized thematic areas were malaria epidemiology, case management and data management. The consensus opinion was the MSC would have a positive impact on the performance of program managers. All managerial participants were willing to release their staff for the MSC and encouraged step-down training. However, most participants opined they could not guarantee that their institutions would provide financial support to the MSC attendees. CONCLUSIONS: Implementing the MSC for program managers was considered essential towards achieving malaria control. Moreover, there is need for prioritized funding and sustainability mechanisms to actualize the implementation of the course.

Determinants of intermittent preventive treatment of malaria among women attending antenatal clinics in primary health care centers in Ogbomoso, Oyo State, Nigeria.

INTRODUCTION: Despite the effectiveness of intermittent preventive treatment in pregnancy using sulphadoxine-pyrimethamine (IPTp-SP), the uptake and coverage in southwest Nigeria are low. We assessed the factors influencing utilisation of IPTp-SP. METHODS: A multistage sampling technique was used to select 400 pregnant women from six primary healthcare centers in Oyo State. Data on socio-demographic characteristics, knowledge, attitude towards IPTp-SP and its utilisation were obtained using a semi-structured questionnaire. Data were analyzed using SPSS software. Focus group discussions (FGD) and key informant interviews (KII) were held for pregnant women and healthcare workers and analysed thematically. RESULTS: Mean age of respondents was 27.2 (SD ± 5.5) years. Mean gestational age was 29.5 weeks (SD ± 5.4). Overall, 320 (80.0%) took SP, of which 152 (47.5%) took 2 doses and 112 (35.0%) took under directly observed therapy (DOT). We found that early booking for ANC, more than two visits to ANC (adjusted odds ratio (aOR) = 5.6; 95% CI: 1.2 - 26.6), good knowledge on IPTp (aOR = 9.3; 95% CI: 5.4 - 16.0), positive attitude towards IPTp (aOR = 2.1; 95% CI: 1.5 - 2.9) and being employed (aOR = 1.4; 95% CI: 1.1 - 1.7) were factors associated with IPTp-SP utilisation. The FGD and KII revealed that IPTp-SP drugs were mostly taken at home due to stock out. CONCLUSION: Late ANC booking with stock out of IPTp-SP drugs was responsible for its low utilisation. There is need to encourage pregnant women to book early for ANC. Adherence to the practice of DOT scheme is recommended to improve IPTp-SP utilisation.

Health care seeking behaviour for visual dysfunction among motor vehicle drivers in Osun State, Southwest Nigeria.

INTRODUCTION: Visual impairment is recognized as a public health problem worldwide. People and generally drivers do not often go for routine medical or eye examination based on varied reasons. This study assessed health care seeking behaviour for visual dysfunction among motor vehicle drivers in Osun state, Southwest Nigeria. METHODS: This was a comparative cross-sectional study among 120 male commercial and 120 government drivers, selected using multi-stage sampling technique in Osogbo, Osun State. Data on knowledge, attitude and health seeking behavior of drivers for visual dysfunction and barriers for not seeking medical treatment was collected using a pre-tested semi-structured questionnaire. Questions on awareness about visual functions and attitude of the respondents concerning visual problems were scored. Two sample independent t-test was used to elicit association between mean age/knowledge of government and commercial drivers and health seeking behavior for visual dysfunction. RESULTS: The mean age of government and commercial drivers was 44.53years ± 8.51 and 38.52years ± 8.60 respectively. The mean knowledge (p<0.001) and attitude (p=0.001) differences of government and commercial drivers were associated with health seeking behavior for visual dysfunction. Of the 120 government drivers, 24 (20.0%) were aware of their current visual problems. Of the 24, government drivers, 10 (47.6%) visited the hospital for treatment. Busy workplace schedule (n = 5, 20.8%) and lack of awareness of visual defects ((n= 3, 12.5%) by commercial drivers were identified barriers for not seeking medical treatment for visual dysfunction. CONCLUSION: Knowledge and attitude towards visual dysfunction were higher among the government drivers compared to commercial counterparts. Government drivers had better health seeking behavior for visual dysfunction as compared to their commercial counterparts. We recommended routine eye medical check-up for early detection of visual dysfunction in motor vehicle drivers.
