Case study of a model primary health care program in Nigeria: History, evolution, challenges, and future perspectives.

This short report describes the historical evolution of a pioneer Model PHC programme located in Ogun State, southwest Nigeria, as a direct result of the vision and effort of Professor Olikoye Ransome-Kuti, and his drive to entrench the delivery of primary health care (PHC) in Nigeria. It describes some of the programmes inspired by the PHC philosophy at the Model PHC Centre, some of the challenges faced over the years, and the need to reposition the programme. It exemplifies key principles in PHC and its philosophy that are instructive for health practitioners, policymakers and development practitioners, especially those with interest in resource-poor countries.

Cohort event monitoring for safety signal detection in adult individuals 18 years and above after immunisation with coronavirus disease 2019 vaccines in Nigeria.

Introduction: In Nigeria, immunisation with coronavirus disease 2019 (COVID-19) vaccines commenced in March 2021. COVISHIELD from AstraZeneca (AZ), a viral vector vaccine, was the brand administered in the first phase of vaccinations for pre-determined eligible adults 18 years and above. As more brands of COVID-19 vaccines have been introduced in Nigeria, identifying effective and safe vaccine brands is essential to pharmacovigilance and public health. The current study assessed the safety of the AZ-AZD1222 (ChAdOx1) COVID-19 vaccine in adults during the first phase of the vaccination exercise in Nigeria. Methodology: We conducted a descriptive analysis of safety data from selected vaccination sites across six states in Nigeria between June 2021 and September 2021. Respondents were monitored over 3 months for local and systemic reactions, as well as hospitalisation and mortality. Measures obtained from respondents include age, sex, pre-existing comorbidity, local and systemic reactions to vaccines, timing onset of reactions, hospitalisation and mortality. Bivariate and multivariable regression models were used to assess factors associated with vaccine reactogenicity. Results: A total of 1284 individuals were enrolled in the cohort study from the six selected states (Anambra, Borno, Edo, Katsina, Lagos and Plateau) representing the geopolitical zones of Nigeria. A total of 675 individuals or 52.6% of enrolees reported non-serious adverse effects, and only one individual or 0.08% reported a serious adverse event following immunisation in the first 7 days after vaccination. None of the enrolled participants reported adverse events requiring hospitalisation. The most common self-reported symptoms amongst vaccine recipients were tenderness at the injection site 20.9% and fever 20.3%. A majority of symptoms (55.5%) occurred on or before the 3rd day after vaccination. Multivariable logistic regression model showed that age 60 years or above (vs. 18-24 years) was significantly associated with a lower likelihood of a vaccine-related symptomatic reaction (adjusted odds ratio: 0.35; 95% confidence interval: 0.20-0.61). There was no reported mortality amongst all the enrolled and followed-up vaccine recipients. Conclusion: Our findings suggest that the safety profile of the AZ vaccine is acceptable, and the observed symptoms were mild and mostly within the first 3 days following vaccination. Vaccine recipients will benefit from counselling about potential transient reactions, and improving public awareness can potentially encourage the uptake of vaccines and reduce the spread of the COVID-19 pandemic.

Determinants of antiretroviral treatment adherence among patients attending secondary health care facilities in north-east and south-west Nigeria: a comparative study.

BACKGROUND: Four decades after its discovery, HIV continues to be a major global public health issue, even with antiretroviral therapy (ART). Strict adherence to ART remains a challenge, with attendant implications for treatment success. This study aimed at comparing ART adherence between north-east and south-west Nigeria. METHODS: A comparative cross-sectional study was conducted in two regions in Nigeria among 400 HIV/AIDS patients on ART. Data were collected using a pre-tested, semi-structured interviewer-administered questionnaire. Multivariable analysis was performed to determine predictors of ART adherence in the regions. The level of significance was set at 0.05. RESULTS: The majority of respondents from both the north-east (87.5%) and south-west (92.5%) of Nigeria had good knowledge about ART. The self-reported adherence level was 90.0% in the north-east and 87.5% in the south-west. Predictors of ART adherence in the north-east were knowledge about ART (AOR 9.949; 95% CI 2.009-49.284) and transport costs to the clinic (AOR 0.177; 95% CI 0.047-0.661). In the south-west, education (AOR 0.198; 95% CI 0.047-0.832) and knowledge of ART (AOR 8.945; 95% CI 1.749-45.751) were identified as predictors of ART adherence. CONCLUSION: In both regions, knowledge about ART was appreciable, but adherence was sub-optimal. Strategies to support adherence should be tailored to specific predictors in each region.

Hepatitis B and C seroprevalence among residents in Lagos State, Nigeria: A population-based survey.

Background: Hepatitis is one of the leading causes of morbidity and mortality, particularly in developing countries. It is often caused by hepatitis B and C, which are both preventable and treatable. Available information on Hepatitis B and C in Nigeria is based primarily on estimates obtained from specific population sub-groups or hospital-based surveys leaving gaps in population-level knowledge, attitudes, and prevalence. This study aimed to assess the knowledge, attitude and associated factors of hepatitis B virus (HBV) and hepatitis C virus (HCV) infections amongst residents of Lagos State. Methodology: This was a community-based descriptive cross-sectional study carried out in all the 20 local government areas of Lagos state using a multistage sampling technique. Data were collected using pre-tested interviewer-administered questionnaires. Blood samples were taken (pinprick) from respondents (n = 4862) and tested using hepatitis B and C surface antigen tests after obtaining informed consent. Results: The overall prevalence of HBV infection in Lagos State was 2.1% while the prevalence of HCV infection was 0.1%. Only about half of all the respondents (50.9%) had heard about hepatitis B before the survey. Knowledge of the specific symptoms of HBV was also very low. For instance, only 28.1% of the respondents knew that yellowness of the eyes is associated with hepatitis while < 1% (0.1%) knew that HBV infection is associated with the passage of yellow urine. The most common source of information about hepatitis was the radio (13.0%). Only 36.2% of the respondents knew that HBV infection could be prevented. Overall, 28.8% of the respondents were aware of the hepatitis B vaccine. Less than half (40.9%) felt it was necessary to get vaccinated against HBV, however, a similar proportion (41.9%) would want to be vaccinated against HBV. Only 2.5% of all the respondents had ever received HBV vaccines while 3.5% had ever been tested for hepatitis B before this survey. There was a statistically significant association between HBV infection and respondents' use of shared clippers and work exposure involving contact with body parts and body fluids (P < 0.05). Conclusion: The knowledge, awareness and risk perception of HBV infection were low, however, almost half of the residents were willing to receive hepatitis B vaccinations if offered. It is recommended that the population-based prevention programmes and regular community-based surveillance be conducted by the public health department of Lagos State Ministry of Health. In addition, the strengthening of routine immunisation and vaccination of high-risk groups should be prioritised.

Socio-economic behavioural indicators of falciparum malaria parasitaemia and moderate to severe anaemia among pregnant women attending antenatal clinics in Lagos, Southwest Nigeria.

BACKGROUND: Incidence of malaria and anaemia are of public health importance especially in pregnant women in endemic regions, due to the negative health consequences to the mother and fetus. This study aimed to assess the pattern of falciparum malaria infection and anaemia, based on malaria prevention methods practiced by participants. METHODS: A semi-structured tool was used to capture information on demographic, socio-economic and malaria prevention practices from 113 pregnant women attending antenatal clinics in 2 peri-urban health facilities in Lagos, southwest Nigeria. Malaria microscopy was conducted and haematocrit was measured. Logistic regression analysis was performed on the data collated from the survey. RESULTS: The prevalence of anaemia among pregnant women was 87.2%. The mean (± sd) packed cell volume (PCV) (%) of the 22 (19.5%) infected subjects (26.8 ± 6.6), was significantly lower (t = -2.60, P value = 0.007) than that of the 91 (80.5%) uninfected subjects (30.8 ± 6.0). The prevalence of infection was highest in the 3rd trimester (n = 40, 35.4%) at 27.5% (11/40) and among those in their first pregnancy (n = 32, 28.3%) at 25.0% (8/32). There was a significant difference (t = -2.23, P-value = 0.01) in the mean PCV % of pregnant women who consumed herbal teas in pregnancy (28.2 ± 5.2) compared to those who did not (30.8 ± 6.6). Regression analysis showed that first pregnancy, anti-malarial use and insecticide-treated nets use the night before study had increased odds of malaria infection in participants (OR = 1.35, P = 0.006, 95% CI 0.52-2.49; OR = 2.3, P = 0.005, 95% CI 0.14-0.41; OR = 1.92, P = 0.001, 95% CI 0.62-5.98) while intermittent preventive treatment (IPT) participation and formal education were strongly and significantly associated with lower risk of parasitaemia (OR = 0.95, P = 0.025, 95% CI 0.41-2.26; OR = 0.44, P = 0.005, 95% CI 0.34-10.50). CONCLUSION: Interventions that will reduce malaria and moderate to severe anaemia, especially in a first pregnancy, should include education on the correct use of long-lasting insecticide-treated bed nets (LLIN), IPT and the dangers of herbal teas in pregnancy.

A malariometric survey of under-fives residing in indoor residual spraying-implementing and non-implementing communities of Lagos, Nigeria.

BACKGROUND: Indoor residual spraying (IRS) is used as part of the integrated vector management strategy for the control of malaria in Lagos, Nigeria. The purpose of this study was to compare the malariometric indices of children under 5 years old living in IRS-implementing and non-IRS-implementing communities of Lagos, Nigeria. METHODS: The study was a community-based, comparative, cross-sectional study of 480 children under five recruited using a multi-stage sampling method. Data on each child were collected using a household questionnaire administered to the consenting care-giver of each selected child. Each child underwent a comprehensive physical examination. On-the-spot malaria rapid diagnostic testing and haemoglobin estimation to assess parasitaemia and anaemia, respectively, were also carried out. Risk factors for parasitaemia and anaemia were identified using multivariate logistic regression. RESULTS: A total of 238 children were studied in the IRS-implementing group while 242 children were studied in the non-IRS-implementing group. The IRS -implementing community had a lower level of parasitaemia (1.3 %) compared to the non-IRS-implementing community (5.8 %) (p < 0.001). There was no significant difference in anaemia, spleen rate and fever in the IRS-implementing group (10.9, 9.7 and 5 %) and the non-IRS-implementing group (9.9, 8.8 and 8.7 %), respectively. Residing in an IRS-implementing community was associated with lower odds of parasitaemia (OR 0.17, p < 0.01). Sleeping under a bed net was the only factor associated with anaemia (p < 0.01). CONCLUSION: IRS has led to a reduction in the level of parasitaemia in the under-fives in the study areas.

Sexually transmitted infections: prevalence, knowledge and treatment practices among female sex workers in a cosmopolitan city in Nigeria.

Sexually transmitted infections constitute economic burden for developing countries, exposure to causative agents is an occupational hazard for female sex workers. Targeted interventions for this population can reduce the incidence and prevalence of sexually transmitted infections including human immunodeficiency virus, but barriers exists which can hinder effective implementation of such programs. This descriptive cross sectional study sought to assess the prevalence, knowledge and treatment practices of sexually transmitted infections among brothel based female sex workers. Three hundred and twenty three consenting female sex workers were surveyed using pre tested, interviewer administered questionnaires. More than half of the respondents (54.2%) had poor knowledge of symptoms of sexually transmitted infections. Only 13.9% were aware that sexually transmitted infections could be asymptomatic. The self reported prevalence of symptomatic sexually transmitted infections was 36.5%. About half of those with sexually transmitted infectionss sought treatment in a hospital or health centre while 32.5% from a patent medicine vendor. Most respondents (53.8%) mentioned the perceived quality of care as the main reason for seeking treatment in their chosen place. More of the respondents with good knowledge of sexually transmitted infections reported symptoms compared to those with fair and poor knowledge. The knowledge of sexually transmitted infections among these female sex workers is poor and the prevalence is relatively high. Efforts to improve knowledge promote and encourage preventive as well as effective treatment practices must be made for this population.

Mothers' knowledge, attitude and home management of diarrhoea among children under five years old in Lagos, Nigeria.

BACKGROUND:  Diarrhoea is a leading cause of death among children under five years old globally. It remains a major cause of morbidity and mortality among this age group in Nigeria. Using simple home management, mothers play important roles in the prevention and control of diarrhoea among these children. AIM:  This study aimed to assess mothers' knowledge, attitude and practice in the prevention and home management of diarrhoeal diseases among children under five years old in Lagos, Nigeria. SETTING:  This study was conducted within the communities of Kosofe local government area of Lagos State, Nigeria. METHODS:  A descriptive cross-sectional study design was conducted using a multistage sampling technique. Data were collected using a structured interviewer-administered questionnaire and analysed using EPI info version 7.2.1. Chi-square statistic was used to test the association between variable at the level of significance of 5%. RESULTS:  A total of 360 respondents participated in this study. The mean age of the respondents was 32.5 ± 5.5 years. About 59.2% of respondents had good knowledge, 59.2% of them had positive attitude, and 53.1% of them had good practice towards prevention and home management of diarrhoea. Age (p = 0.007), occupation (p = 0.008) and level of education (p = 0.001) were significantly associated with practice of home management of diarrhoea among children under five years old. CONCLUSION:  Educated, employed, and married mothers were more likely to have good prevention and home management practices towards diarrhoea in their children under five years old.

Sexual behavior and the influencing factors among out of school female adolescents in Mushin market, Lagos, Nigeria.

High rates of adolescent pregnancy, sexually transmitted infections, and unsafe abortions in Nigeria indicate the need for a greater understanding of factors that affect adolescent sexuality. The sexual health needs of adolescents remain poorly known and addressed particularly among vulnerable subpopulations like out-of-school adolescents. The objective of this study was to examine the sexual behavior of female out-of-school adolescents and to identify factors that influence their sexual behavior. This cross-sectional study was conducted among a representative sample of unmarried, out-of-school female adolescents (n = 332, mean age 17 y), selected using cluster sampling, who were working in a major market (Mushin) in Lagos, Nigeria. Data were collected using interviewer administered questionnaires. Many girls (43.7%) have had sexual intercourse. The mean age at initiation was 16 years. The main reason for initiation was curiosity. Risky sexual behavior and transactional sex was common. Nonconsensual sex was also reported. Sexual health knowledge was poor, and friends served as their main source of information on sexual health issues. Factors associated with the initiation of sexual activity were friends sexual behavior, the person adolescents reside with, parents marital status, availability of funds to meet basic needs, and watching pornography (p < .05). Out-of-school female adolescents engaging in risky sexual behavior are exposed to sexual abuse, lack skills to resist pressure, and have limited access to credible reproductive health information. Appropriate interventions including provision of sexuality education and a supportive environment must be instituted to address their needs.

Predictors of tuberculosis knowledge, attitudes and practices in urban slums in Nigeria: a cross-sectional study.

INTRODUCTION: Nigeria is among six countries responsible for the majority of tuberculosis (TB) cases in the world. The Nigerian government has emphasized community-based case finding to increase detection of TB. This process requires efforts to improve knowledge, attitudes and practices (KAP) of TB, particularly in the poorest of communities. This study presents data from a KAP survey administered in two underserved Nigerian communities. METHODS: a structured survey was administered by trained interviewers among adult residents in two slum communities in Lagos, Nigeria. Participants were selected through multistage random sampling. KAP scores were computed and the predictors of higher scores were assessed. RESULTS: a total of 504 respondents were surveyed. The mean KAP scores were relatively low: 9.8 ± 7.1 for knowledge (out of a maximum 34), 5.3 ± 3.4 for attitude (maximum = 10), and 5.2 ± 1.5 for practice (maximum = 7). The predictors of good knowledge were increasing age, post secondary education and professional occupation. The predictors of positive attitude were post secondary education and good TB knowledge. Good knowledge was a predictor of good practice. CONCLUSION: our findings underscore the need to improve the education about TB in underserved communities. Improving KAP scores will ultimately lead to higher rates of TB detection and treatment.

Ending preventable maternal and child deaths in western Nigeria: Do women utilize the life lines?

INTRODUCTION: Nigeria which constitutes just one percent of the world population, accounts for 13% of the world maternal and under-five mortality. Utilization of health care services has been an important determinant of maternal and child outcomes. The vast majority of maternal and child deaths could be prevented if women utilize the available life lines. The study objective was to determine utilization of maternal and child health care services among women of child bearing age in Western Nigeria. METHODS: A community based, cross sectional study was done in Oshodi/Isolo Local Government Area among women of child bearing age (15-49 years) with at least one child under five years. Multistage sampling was used to select 371 respondents. Data was collected with a structured, pretested, interviewer administered questionnaire and analyzed with Epi info 3.5.1. Summary and inferential statistics were done. Level of significance was set at 5%(p<0.05). RESULTS: Of the 371 respondents interviewed, the health facility was used for antenatal care (74.3% n = 276), delivery (59.9% n = 222), postnatal services (77.9% n = 289), family planning services (28.8% n = 107), immunization (95.1% n = 353), growth monitoring (77.4% n = 287), nutritional services (64.7% n = 240) and treatment of childhood illness (49.6% n = 184). Only 31.5% (n = 117) of the respondents practiced exclusive breastfeeding and 82% (n = 263) of the mothers used oral rehydration solution for diarrhoea management. Maternal education significantly influenced utilization. In addition maternal age, employment status, number of children, spouse employment and educational status played significant roles. CONCLUSION: Utilization of maternal and child health services among respondents was above national average but not optimal, especially family planning services, exclusive breastfeeding and curative services for children. Interventions that improve maternal educational status and wealth creation should be undertaken to achieve the SDGs.

Knowledge, perceptions and practice of cervical cancer prevention among female public secondary school teachers in Mushin local government area of Lagos State, Nigeria.

INTRODUCTION: Cervical cancer is the most common gynecological cancer and a leading cause of cancer death in women in Nigeria. This study was aimed to assess the knowledge, perception, and practice of cervical cancer prevention among female public secondary school teachers in Mushin, Lagos. METHODS: This was a cross-sectional study carried out among female secondary school teachers in Mushin, Lagos. The participants were selected by a two-stage random sampling method and relevant data were collected with the use a self-administered questionnaire. Data entry and analysis were done using Epi-info version 7.2 statistical software and descriptive statistics were computed for all data. RESULTS: The knowledge of cervical cancer and its prevention was 100.0% among the respondents. The most commonly known method of cervical cancer screening identified by the respondents was Papanicolaou smear (91.4%). More than half of the women (67.0%) have had at least one cervical cancer screening done previously. Only 2.2% of the respondents have had HPV vaccine given to their female teenage children in the past despite the acceptance rate for HPV vaccination being 76.2%. CONCLUSION: This study, unlike most previous studies in other regions of Nigeria and most part of sub-Saharan Africa, has demonstrated a relatively high level of awareness about cervical cancer, its cause, risk factors and prevention. However, conversely, the absence of a national health programme means that screening and vaccination centers are not available, accessible or affordable.

Trained community volunteers improve tuberculosis knowledge and attitudes among adults in a periurban community in southwest Nigeria.

Nigeria has the world's 10th largest tuberculosis (TB) burden. Targeted community-based interventions can potentially help reduce TB incidence. We designed an intervention in a periurban community where 10 community volunteers were trained to provide community TB education and also detect and refer TB suspects to a nearby clinic. To determine the effect of the intervention on knowledge, attitude, and preventive practices of TB, we compared results from a pre-intervention survey with those of a post-intervention survey. Pre-intervention, respondents had a mean knowledge score of 10.6 ± 7.0 of a possible 34, a mean attitude score of 5.8 ± 3.3 of a possible 10, and a mean practice score of 5.3 ± 1.4 of a possible 7. The intervention significantly increased the mean knowledge score to 16 ± 5.4 (P < 0.001) and mean attitude score to 7.0 ± 1.8 (P < 0.001); however, there was no statistically significant difference in the mean practice score. Eight TB suspects were referred to the clinic, and one suspect was subsequently diagnosed with TB. The use of trained community volunteers to share information on TB improved the overall knowledge and attitudes of respondents. Continued empowerment of the community should be encouraged to promote TB prevention and care.

Exposure to blood among mortuary workers in teaching hospitals in south-west Nigeria.

BACKGROUND: Mortuary workers like other health workers are exposed to blood borne pathogens at work. A baseline assessment is important to plan for programmes to safeguard the health of workers. The aim of this study is to determine exposure rates to blood among mortuary workers in teaching hospitals in South West Nigeria. METHODS: A descriptive cross sectional study was carried out between March and May 2008. All mortuary workers working in six (6) teaching hospitals, 80 in total were included in the study. Data was collected with the aid of a 15- item self administered questionnaire. Data was analysed with the aid of EPI-INFO 2002. Statistical associations were explored using odds ratio and confidence intervals. RESULTS: A total of 76 respondents completed questionnaire giving a response rate of 95%; 3 males and 1 female declined to participate, the mean age of respondents was 38.2 years, 48(72.6%), 53(85.5%) and 50(73.5%) of the workers had been exposed to blood through cuts, blood splash and needle stick injury. Duration at work was significantly associated with blood splash. Workers who had worked 5 years and above were 0.10 times (95% confidence interval 0.00-.0.78) as likely to experience blood splash compared to those who had worked under 5 years. Only 5(10.4%) of workers with needle stick injury had completed three doses of Hepatitis B vaccine. The specific confirmation by antibody titre was however not done in this study. CONCLUSION: Exposure to blood was very common with blood splash emerging as the most common route of exposure. There is a need for vaccination of all mortuary workers with three doses of Hepatitis B Vaccine to protect their health. In addition, education of workers on risks and institution of standard operating procedure are crucial to safeguard the health of mortuary workers.

Awareness of occupational health hazards and the practice of universal safety precautions among mortuary workers in South West Nigeria.

BACKGROUND: Mortuary workers face hazards at work such as infectious diseases, chemical and psychosocial hazards among others. If workers are to participate in activities to safeguard their health, they must be aware of the risks at work. OBJECTIVE: The objective of the study is to assess the awareness of occupational health hazards and to determine their practice of universal safety precautions. METHODS: A descriptive, cross sectional study was carried out among all the mortuary workers in teaching hospitals in South West Nigeria. The study material was a self administered questionnaire used for Data collection between March and May 2008. Data was analyzed by EPI-INFO 2002. The Chi-square test was used for statistical association with a p-value of 0.05. RESULTS: A total of 76 mortuary workers was surveyed with a mean age of 38.2 yrs. They were mostly male (92%). Forty-five (59.2%) of the respondents were aware of hazards at work. The hazards identified were HIV/AIDS (97.7%), tuberculosis (82%) and formalin related morbidity. 14 (18.4%) rated the risk faced at work as moderate/high risk. Only 36.8% always used face masks. About 40 (53.3%) had received at least one dose of Hepatitis B vaccine. There was no association between awareness of hazards and practice of universal safety precautions CONCLUSION: The awareness of occupational hazards among the workers was fair while the practice of universal safety precautions was suboptimal. There is a need for periodic training programmes on occupational hazards as well as the vaccination of all workers with three doses of Hepatitis B Vaccine.

Promoting cessation and a tobacco free future: willingness of pharmacy students at the University of Lagos, Nigeria.

BACKGROUND: Tobacco use is projected to cause nearly 450 million deaths worldwide during the next 50 years. Health professionals can have a critical role in reducing tobacco use. Therefore, one of the strategies to reduce the number of smoking-related deaths is to encourage the involvement of health professionals in tobacco-use prevention and cessation counseling. As future health care providers, pharmacy students should consider providing assistance to others to overcome tobacco use and be involved in promoting a tobacco free future as part of their professional responsibility. This research was to determine the knowledge of tobacco/smoking policy, willingness to be involved in tobacco cessation, attitude to keeping a tobacco free environment and the smoking habit among pharmacy students at the University of Lagos. METHODS: Data was collected by the use of self administered questionnaire which was aimed at assessing their smoking habit, determining their knowledge and attitude to smoking policy and willingness to be involved in smoking cessation. The population sample was all the pharmacy students in their professional years (200 to 500 Levels) at Idi-Araba Campus of the University of Lagos. RESULTS: Out of 327 qualified participants, 297 responded to the questionnaire which was about 91% participation rate but out of these only 291 questionnaires were useful which came to 89%. There seemed to be no statistically significant difference between the smoking habits among the different levels (p > 0.05). Overall, the current smoking prevalence was 5.5% which is lower than the national prevalence rate of 8.9%. Awareness of WHO FCTC global tobacco treaty was low (9.3%) among pharmacy students but they agreed that pharmacists and pharmacy students should be involved in quit smoking program (93.1%) and they were willing to be involved in helping smokers to quit (85.9%). Majority agreed that smoking should not be permitted in pharmacies (87.9%) and at pharmacy students' events (86.9%). CONCLUSION: From this study it can be concluded that smoking prevalence is low among pharmacy students at the University of Lagos. Awareness of global policy is low but they are willing to be involved in smoking cessation and promoting a tobacco free future.
