Addressing the Global Burden of Cardiovascular Disease in Women: JACC State-of-the-Art Review.

Cardiovascular diseases (CVDs) are responsible for approximately 35% of all deaths in women. In 2019, the global age-standardized CVD prevalence and mortality of women were 6,403 per 100,000 and 204 per 100,000, respectively. Although the age- and population-adjusted prevalence has decreased globally, opposite trends are evident in regions of socioeconomic deprivation. Cardiovascular health and outcomes are influenced by regional socioeconomic, environmental, and community factors, in addition to health care system and individual factors. Cardiovascular care in women is commonly plagued by delayed diagnoses, undertreatment, and knowledge gaps, particularly in women-specific or women-predominant conditions. In this paper, we describe the global epidemiology of CVD and highlight multilevel determinants of cardiometabolic health. We review knowledge and health care gaps that serve as barriers to improving CVD outcomes in women. Finally, we present national, community, health care system, and research strategies to comprehensively address cardiometabolic risk and improve outcomes in women.

Hypertension: risk perception and health seeking behaviour of long-distance drivers in Port Harcourt.

Background: Driving as an occupation is associated with the occurrence of heart-related diseases such as hypertension. Objectives: To assess the perception of modifiable risk factors of hypertension and the health seeking behaviour of long-distance commercial bus drivers in Port Harcourt Metropolis. Methods: A cross-sectional study design was used to obtain data from 272 long distance commercial drivers. Data were analysed descriptively using SPSS version 24.0. (p≤0.05). Results: A total of 272 questionnaires were completed and returned (100%). Respondents' mean age was 43.4 ± 8.9. In scoring for perception of modifiable risk factors of hypertension among the drivers, (45.6%) respondents had a high perception score while 148 (54.4%) respondents had a low perception score. In assessing for health seeking behaviour, 190 (69.9%) had checked their blood pressure at least once in their lifetime, 80 (42.1%) of those who had checked, did so over a year ago. However, 18 (9.5%) respondents were on medication for hypertension in the last one month. Conclusion: This study showed that a greater number of the drivers had a low perception of modifiable risk factors of hypertension. Regular health checks were also not observed among participants. There is need for targeted health education for this group.

Adoption of electronic medical records in developing countries-A multi-state study of the Nigerian healthcare system.

Electronic medical records (EMR) are extensively used in developed countries to manage patient records and facilitate consultations and follow-up of treatment. This has resulted in centralised databases where different services and clinicians can quickly access patient data to support healthcare delivery. However, adoption and usage of EMR in developing countries is not common and, in most cases, non-existent. Clinicians are dependent on patients keeping their own records manually with no centralised database to manage and control the patient medical history. The key objective of this study was to investigate the propensity of clinicians and senior management personnel in healthcare facilities to adopt EMR and evaluate the contextual factors that impact or impede adoption. Using Davis's technology adoption model extended with other factors, this study determined if contextual or situational factors are associated with barriers that impede adoption of EMRs in developing countries. Using a cross-sectional quantitative research approach, a questionnaire was designed to collect data across four states in the Niger Delta region of Nigeria. Stratified random sampling was used to select healthcare facilities that participated in the survey and selection of respondents from each healthcare facility. Data was collected by trained research assistants and a total of 1,177 valid responses were received and analysed using factor analysis and multiple regression analysis. The results from the analysis show that usefulness, critical success factors, awareness and relative advantage significantly influence clinicians' intention to adopt EMRs. Surprisingly, infrastructure availability was not statistically significant. Meanwhile, risk and data security both negatively influence adoption, indicating that user perception of risk and safety of their data decreases their propensity to adopt EMRs. The results from this study suggests that usefulness and anticipated success factors in facilitating operations within healthcare facilities have a great influence on user adoption of EMRs. Awareness, training and education of users on the effectiveness of EMRs and their usefulness will increase adoption. The results will be beneficial in helping government and healthcare leaders formulate policies that will guide and support adoption of EMR. Other policy recommendations and suggestions for future research were also proffered.

The Case for Early and Universal Screening for Gestational Diabetes Mellitus: Findings from 9314 Pregnant Women in a Major City in Nigeria.

INTRODUCTION: Risk-based screening has been replaced by universal screening as the recommended course of care for gestational diabetes mellitus (GDM). As of 2016, no state in Nigeria had implemented a policy of universal screening for GDM. This research aimed to assess findings from a universal screening programme and its implication for scaling up universal and early screening for GDM. METHODS: This was a descriptive cross-sectional study conducted in Rivers State Nigeria between February 2017 and January 2020. Multistage sampling was used to recruit 9314 pregnant women from 30 primary, secondary, and tertiary health facilities in the state. An interviewer-administered structured questionnaire was used by trained healthcare workers to collect socio-demographic, obstetric and medical information. All study participants had a plasma glucose test on their first hospital visit and a diagnosis made using the World Health Organization (WHO) criteria. Data obtained was analysed using the IBM Statistical Package for Social Sciences (SPSS) version 23. RESULTS: Most women [5683 (61.0%)] were aged 25-34 (mean 29.60 ± 5.64) years. The prevalence of GDM in this study was 5.2% with a prevalence of GDM in the first, second and third trimesters of 4.9%, 4.2% and 6.7%, respectively. The prevalence of GDM among persons with a family history of diabetes was 13.2% (97 persons) while 4.6% (391 persons) without family history were diagnosed with GDM. Gestational age, family history of diabetes and age group were found to be significant predictors of GDM among the study participants after adjusting for confounding variables. CONCLUSION: The practice of universal screening was useful in identifying GDM in 1 out of 20 pregnant women in the study sample. Screening at all trimesters was useful in identifying GDM. There is an urgent need to scale up early and universal screening for GDM across sub-Saharan Africa.

Awareness, perception and the practice of COVID-19 prevention among residents of a state in the South-South region of Nigeria: implications for public health control efforts.

BACKGROUND: As with any epidemic, coronavirus disease 2019 (COVID-19) has evoked panic, fear and misconceptions. The risk communication pillar of the Public Health Emergency Operations Centre is responding to the pandemic by facilitating correct and consistent information to enable the adoption of behaviours to prevent and control COVID-19. This study explored awareness, perception and practice of COVID-19 prevention among residents in Rivers State, Nigeria, during the early stages of the COVID-19 pandemic response. METHODS: This was a descriptive cross-sectional survey among 1294 adult residents across all districts of the state. It employed an interviewer-administered questionnaire. Knowledge was graded as excellent for scores of ≥80%, good for scores of 50-79% and poor for scores of <50%. Respondents who washed all critical parts of their hands were categorised as adopting correct handwashing practice. Regression modelling was employed to determine predictors of knowledge and practice of COVID-19 prevention with p=0.05. RESULTS: The respondents were aged 18-80 y with an average age of 39.6 (SD=11.9) y. A total of 710 (54.9%) were male, 476 (36.8%) were unemployed with 685 (52.9%) having secondary education. The most common sources of information about COVID-19 were radio jingles (1102; 86.7%) and television adverts (940; 74.0%). Overall, 608 (47.0%) of the respondents had a poor knowledge of COVID-19. About 443 (34.9%) respondents believed they were unlikely to contract the virus. Only 505 (39.0%) of respondents washed all the critical parts of their hands correctly. Occupation (adjusted OR [AOR]=1.39, 95% CI 1.07 to 1.82, p=0.01), level of education (AOR=4.71, 95% CI 1.90 to 11.68, p<0.001) and location (AOR=1.75, 95% CI 1.29 to 2.38; p<0.001) significantly predicted respondents' knowledge about COVID-19. The significant predictors of practice of COVID-19 were age (AOR=0.60, 95% CI 0.42 to 0.84, p=0.003), occupation (AOR=1.93, 95% CI 1.41 to 2.63, p<0.001), location (AOR=2.35, 95% CI 1.65 to 3.34, p<0.001) and knowledge about COVID-19 (AOR=7.75, 95% CI 5.94 to 10.11, p<0.001). CONCLUSIONS: Broadcast media has a pivotal role to play in risk communication for behavioural change for the control of current and future epidemics in this population.

Polycyclic Aromatic Hydrocarbon Levels in Wistar Rats Exposed to Ambient Air of Port Harcourt, Nigeria: An Indicator for Tissue Toxicity.

This study investigated the PAH levels in Wistar rats exposed to ambient air of the Port Harcourt metropolis. Twenty Wistar rats imported from a nonpolluted city (Enugu) were exposed to both indoor and outdoor air. Following the IACUC regulation, baseline data were obtained from 4 randomly selected rats, while the remaining 16 rats (8 each for indoor and outdoor) were left till day 90. Blood samples were obtained by cardiac puncture, and the PAH levels were determined using Gas Chromatography Flame-Ionization Detector (GC-FID). GraphPad Prism (version 8.0.2) Sidak's (for multiple data set) and unpaired t-tests (for two data sets) were used to evaluate the differences in group means. Seven of the PAHs found in indoor and outdoor rats were absent in baseline rats. The mean concentrations of PAH in indoor and outdoor animals were higher than those of baseline animals, except for Benzo(a)pyrene, which was found in baseline animals but absent in other animal groups. Additionally, Dibenz(a,h)anthracene, Indeno(1,2,3-c,d)pyrene, Pyrene, 2-methyl, and other carcinogenic PAHs were all significantly higher (p < 0.05) in outdoor groups. The vulnerable groups in Port Harcourt are at the greatest risk of such pollution. Therefore, urgent environmental and public health measures are necessary to mitigate the looming danger.

Clinical and epidemiological characteristics of 646 hospitalised SARS-Cov-2 positive patients in Rivers State Nigeria: a prospective observational study.

INTRODUCTION: the knowledge of epidemiologic and clinical variables in patients with SARS- CoV-2 infection provides evidence and lessons that are useful for the pandemic response, with consideration of National and sub-National variations. The objective of this study was to characterize and describe the clinical and epidemiologic features of all the hospitalised patients with COVID-19 in Rivers State Nigeria, from March to August 2020. METHODS: a prospective descriptive multi-center study of patients with positive SARS-CoV-2 RT PCR, who were hospitalised for treatment and self-isolation in four treatment centers in Rivers state, Nigeria. RESULTS: the mean age of all the patients was 39.21 ± 12.31 years, with a range of 2 to 77 years. The majority of patients were in the 31 to 40-year (33.0%), 41 to 50-year (23.1%) and 18-to 30-year (22.0%) age groups. The patient population included 474 (73.4%) males and 172 (26.6%) females, with 93 (14.4%) healthcare workers. A history of contact and travel was established in 38.5% and at least one comorbid disease condition was present in 32.8% of patients. Patients with severe disease were 61 (9.45%), while the overall case fatality rate was 2%. The leading comorbid disease conditions were Hypertension in 23.8% and diabetes in 7.7% of patients. Fever (26.0%), dry Cough (17.6%), dyspnoea (12.7%), anosmia (12.7%) and headache (9.9%) were the most common symptoms. The presence of comorbidity and increasing age predicted death from COVID-19. CONCLUSION: the clinical and epidemiologic characteristics of this cohort of hospitalised patients show significant similarities with existing trends from previously reported studies, with contextual peculiarities.

Multisystem inflammatory syndrome (MIS-C) in an adolescent Nigerian girl with COVID-19: A call for vigilance in Africa.

Most reports of Multisystem Inflammatory Syndrome (MIS-C) have come from Europe and North America. The paucity of reports in Africa is in contrast with the demographics of the series in New York, Paris and UK with children of African ancestry accounting for over 40% of all cases of MIS-C. With the global trend of higher prevalence of MIS-C in children of African ancestry, enhanced surveillance and awareness for this syndrome in children with COVID-19 in Africa are therefore important. A case report of a 12-year-old Nigerian girl with MIS-C is presented in line with the WHO global surveillance especially in areas were MIS-C is considered a rarity. This case report stimulates a call for vigilance and expanded effort at surveillance to promote early recognition and diagnosis of MIS-C in Nigeria and Africa. The favourable outcome and experience from this case will create awareness, expand knowledge, and support clinicians in Nigeria and the African continent in their approach to other potential cases.

Outcomes of the Deployment of the Auto-Visual Acute Flaccid Paralysis Detection and Reporting (AVADAR) System for Strengthening Polio Surveillance in Africa From 2017 to 2018: Evaluation Study.

BACKGROUND: As we move toward a polio-free world, the challenge for the polio program is to create an unrelenting focus on smaller areas where the virus is still present, where children are being repeatedly missed, where immunity levels are low, and where surveillance is weak. OBJECTIVE: This article aimed to describe a possible solution to address weak surveillance systems and document the outcomes of the deployment of the Auto-Visual Acute Flaccid Paralysis Detection and Reporting (AVADAR) project. METHODS: This intervention was implemented in 99 targeted high-risk districts with concerns for silent polio circulation from eight countries in Africa between August 1, 2017, and July 31, 2018. A total of 6954 persons (5390 community informants and 1564 health workers) were trained and equipped with a smartphone on which the AVADAR app was configured to allow community informants to send alerts on suspected acute flaccid paralysis (AFP) and allow health worker to use electronic checklists for investigation of such alerts. The AVADAR and Open Data Kit ONA servers were at the center of the entire process. A dashboard system and coordination teams for monitoring and supervision were put in place at all levels. RESULTS: Overall, 96.44% (24,142/25,032) of potential AFP case alerts were investigated by surveillance personnel, yielding 1414 true AFP cases. This number (n=1414) reported through AVADAR was higher than the 238 AFP cases expected during the study period in the AVADAR districts and the 491 true AFP cases reported by the traditional surveillance system. A total of 203 out of the 1414 true AFP cases reported were from special population settings, such as refugee camps and insecure areas. There was an improvement in reporting in silent health areas in all the countries using the AVADAR system. Finally, there were 23,473 reports for other diseases, such as measles, diarrhea, and cerebrospinal meningitis, using the AVADAR platform. CONCLUSIONS: This article demonstrates the added value of AVADAR to rapidly improve surveillance sensitivity. AVADAR is capable of supporting countries to improve surveillance sensitivity within a short interval before and beyond polio-free certification.

Investigating client satisfaction with antiretroviral treatment services in South-South Nigeria.

Client satisfaction is a key method of evaluating the quality of healthcare services. This research investigated client satisfaction with anti-retroviral treatment services in selected outpatient facilities in Rivers State. This study was a qualitative study carried out in four antiretroviral treatment (ART) facilities in Rivers State, Nigeria. Researchers conducted nine Key Informant Interviews (KIIs), 25 In-depth interviews (IDIs) and eight Focus Group Discussion (FGDs) among 73 Persons Living with HIVs (PLHIVS) consisting of 31 males and 42 females, using a topic guide. Interviews were recorded, transcribed and analysed using thematic content analysis. Majority of study participants interviewed reported being very satisfied with confidentiality, health worker attitude, interpersonal communication, counselling, and availability of drugs. The major sources of dissatisfaction included overcrowding, long waiting time and inadequate/expensive laboratory services. Suggestions proffered for improving the quality of care at the centres included increasing staff strength at the treatment centres, improving the quality and cost of laboratory services, and infrastructure upgrade. This study demonstrates the role health workers and facility processes play in satisfaction with services at HIV treatment centres. Health workers, programme officers, and managers in HIV prevention, care and treatment need to pay attention to these issues if they would be successful in improving the quality of care for PLHIVs.

The quality of public sources of drinking water in oil-bearing communities in the Niger Delta region of Nigeria.

Background: Studies carried out in the Niger Delta region of Nigeria have demonstrated a link between oil exploration and poor-quality drinking water. However, many of these studies have been limited by small coverage and focus on few parameters. This study thus aimed at a comprehensive assessment of the quality of public sources of drinking water in three gas flaring and three non-gas flaring communities in the Niger Delta region of Nigeria. Methods: A total of 13 samples were collected from the major sources of drinking water in six communities in Rivers, Bayelsa and Delta States, Nigeria. These were stored and transported in line with International standards to a certified environmental laboratory where physical, chemical, bacteriological and petro-chemical assessments were conducted for 27 parameters. Results: Some samples had a pH below the normal range for drinking water, with median pH value of 4.63. All chemical parameters assessed fell below the normal acceptable range with exception of magnesium which exceeded the acceptable range. There were11 samples (91.7%) with microbial contamination; total and faecal coliform demonstrated at values ranging between 15 and 90 most probably number (MPN)/100 ml for total coliform and 9 to 23 MPN/100 ml for faecal coliforms. Oil, grease and total petroleum hydrocarbons (TPH) were identified in water samples from all communities. Values for oil and grease ranged between <0.001 and 0.015 mg/l, while TPH values were between <0.001 and 0.046 mg/l. There was no significant difference between median values in gas flaring and non-gas flaring communities. Conclusion: Distortion of physico-chemical properties, and hydrocarbon and faecal contamination of drinking water are a major challenge in oil-bearing communities in the Niger Delta region of Nigeria irrespective of gas flaring status. This calls for urgent interventions to improve the quality of drinking water for the people of the Niger Delta.

Investigating client satisfaction with antiretroviral treatment services in South-South Nigeria

Methanol poisoning in South- South Nigeria: Reflections on the outbreak response.

The methanol poisoning outbreak in Rivers State in May 2015, involved 84 persons in five local government areas. An incident management system comprised of an Emergency Preparedness and Response (EPR) committee and the Local Government Area Rapid Response Teams in an Emergency Operations Centre (EOC). The EOC teams conducted case finding activities, line listing, and descriptive analysis, a retrospective cohort study and collection of local gin samples for laboratory investigation. They also coordinated community mobilization and sensitization activities, intervention meetings with local gin sellers, trace back activities and case management. Those affected were male (72; 85.7%) aged between 20 and 79 years. Of the 55 persons whose socio-demographics were obtained, forty-one persons (74.6%) were married, and 23 (41.8%) had primary education. Case fatality rate was 83.3% with an attack rate of 16 per 100,000 persons. Those exposed to ingestion of adulterated gin were six times more likely to develop methanol poisoning than those not exposed RR=6 (1.0-38.5); P=0.0078. It is hoped that this experience has positioned the state for better preparedness towards future outbreaks.

The role of the Deki Reader™ in malaria diagnosis, treatment and reporting: findings from an Africare pilot project in Nigeria.

BACKGROUND: The Deki Reader is a diagnostic device used with rapid diagnostic tests (RDTs) and linked to an online database for real-time uploads of patient information and results. This is in contrast to visual interpretation of malaria RDTs recorded on the District Health Information System (DHIS). This paper compares records for use of the Deki Reader with DHIS records of visual interpretation of RDTs. RESULTS: A total of 4063 patient encounters/tests were recorded on the Deki Reader database between June 1st and December 31st, 2016. These tests were for 2629 persons who presented with fever and had RDT done. In comparison, data from DHIS 2.0 for same period recorded 7201 persons presenting with fever. 2421 out of the 2629 persons (92.1%), received RDT using Deki Reader compared to 6535 out of 7201 persons (90.4%) recorded on DHIS (p = 0.04). From DHIS records, malaria positivity rate was 51.6% (3375 out of 6535 persons) compared to Deki Reader records of 23.6% (572 out of 2421 persons). The difference between these two rates was significant (p < 0.001). The odds ratio (95% CI) for the association between use of Deki Reader and having a positive malaria result was 0.29 (0.26-0.32). DHIS showed that 4008 persons received Artemisinin-based combination therapy (ACT) while 3989 persons tested positive with RDT or microscopy, compared to 691 out of 705 persons (98.0%) using Deki Reader. Finally, Deki Reader identified 618 processing and manufacturers errors with an error rate of 15.3%. CONCLUSION: The Deki Reader is likely a useful tool for malaria diagnosis, treatment, and real-time data management. It potentially improves diagnostic quality, reduces wastage in ACT administration and improves data quality.

Mainstreaming youth-friendly health services into existing primary health care facilities: experiences from South-South Nigeria.

Background Youth friendly services, an evidence based approach to overcome the barriers experienced by youths in accessing care, is poorly implemented. The Medical Women's Association of Nigeria (MWAN) Rivers State chapter, was supported by Ford Foundation to mainstream youth-friendly health services (YFHS) into existing primary health care facilities in two hard-to-reach communities. This paper presents the interventions, findings, challenges and recommendations. Methods This study project was implemented in stages: design, baseline survey, interventions and evaluation, between 2014 and 2016. Interventions included facility modifications, health worker capacity building, school and community outreaches, peer group activities, and interpersonal communication. Pre-and-post-intervention surveys were carried out among in- and out-of-school youths to determine the effects of the interventions. Results The most commonly stated barriers to uptake of youth friendly health services included: unavailability of services (154; 33.1%), unavailability of health care workers (167; 38.9%), unaffordability of services (108; 45.8%) and difficulty in communicating with health workers (85; 36.0%). Post-intervention, utilization improved across all services while the perception of barriers to utilization of services reduced (p < 0.05). The interventions implemented increased the odds of youths utilizing YFHS 1.81 times (95% CI = 1.39-2.37). Conclusion Facility modifications, capacity building of health workers, school and community outreaches, peer group activities, and interpersonal communication improved utilization across all services while the perception of barriers to utilization of services reduced. Implementation of YFHS is impacted by external factors often beyond the control of project implementers. Innovative solutions outside of routine health care delivery systems are critical for success. Further evaluation to explore the effect of these interventions is needed. Strengthening of health systems remains a vital strategy for scale-up of YFHS.

End malaria for good: a review of current strategies and future novelties for malaria elimination in Nigeria.

Malaria is endemic in 91 countries and territories. Currently, over half of the world's population is at risk for malaria with malaria prevalence in sub-Saharan Africa remaining the highest in the world. Nigeria accounts for 56% of malaria cases in the West African sub-region. Malaria control is historically the oldest control programme in Nigeria, having been in existence since 1948. Malaria control in Nigeria is guided by National Malaria Strategic Plans. The goal of the NMSP (2014-2020) is 'to reduce malaria burden to pre-elimination levels and bring malaria-related mortality to zero' using strategies under seven strategic objectives. The theme for the 2017 World Malaria Day activities was 'End Malaria for Good'. This theme indicates a sustained push for national and international commitments toward goal zero. Although the prevalence of malaria has dropped significantly, from 42% in 2010 to 27.4% in 2015, a lot of effort needs to be made to actualise a malaria-free Nigeria. This review discusses the current strategies in place to control and eliminate malaria. It also describes some future novelties available to sub-Saharan Africa and Nigeria to 'End Malaria for Good.'

Is living in a gas-flaring host community associated with being hypertensive? Evidence from the Niger Delta region of Nigeria.

BACKGROUND: Researchers have linked gas flaring to climate change, the hastening of the epidemiological transition and an upsurge in the prevalence of non-communicable diseases. We sought to determine if a relationship exists between residing in a gas-flaring host community and hypertension. METHODS: We conducted an analytical cross-sectional household survey among residents of 600 households in three gas-flaring and three non-gas-flaring host communities in the Niger Delta region of Nigeria. We took geo-coordinates, administered a modified WHO-STEPS questionnaire and built on Android mobile phones using Open-Data-Kit (ODK) software. We also took biological measurements and carried out descriptive and inferential statistical analysis using SPSS and STATA. RESULTS: We interviewed a total of 912 adults: 437 (47.9%) from non-gas-flaring and 475 (52.1%) from gas-flaring host communities. There were differences in level of education (x2=42.99; p=0.00), occupation category (x2=25.42; p=0.00) and BMI category (x2=15.37; 0.003) among the two groups. The overall prevalence of hypertension was 23.7%: 20.7% among persons living in non-gas-flaring host communities compared with 25.3% among persons living in gas-flaring host communities (x2=2.89; p=0.89). Residence in a gas-flaring host community, (AdjOR=1.75; 95% CI=1.11 to 2.74) and mean age (AdjOR=1.05; 95% CI=1.03 to 1.07) were identified as the predictors of hypertension. There was a significant association between hypertension and age, 1.05 (1.04-1.06) while the probability of being hypertensive was higher among residents of gas-flaring host communities between 20 to 40 years and 60 to 80 years. CONCLUSION: There is a need for the relevant agencies to scale up environmental and biological monitoring of air pollutants. The implication of a possible relationship between gas-flaring and hypertension brings to the fore the need for interventions to regulate gas-flaring activities.

Using Android and Open Data Kit Technology in Data Management for Research in Resource-Limited Settings in the Niger Delta Region of Nigeria: Cross-Sectional Household Survey.

BACKGROUND: Data collection in Sub-Saharan Africa has traditionally been paper-based. However, the popularization of Android mobile devices and data capture software has brought paperless data management within reach. We used Open Data Kit (ODK) technology on Android mobile devices during a household survey in the Niger Delta region of Nigeria. OBJECTIVE: The aim of this study was to describe the pros and cons of deploying ODK for data management. METHODS: A descriptive cross-sectional household survey was carried out by 6 data collectors between April and May 2016. Data were obtained from 1706 persons in 601 households across 6 communities in 3 states in the Niger Delta. The use of Android mobile devices and ODK technology involved form building, testing, collection, aggregation, and download for data analysis. The median duration for data collection per household and per individual was 25.7 and 9.3 min, respectively. RESULTS: Data entries per device ranged from 33 (33/1706, 1.93%) to 482 (482/1706, 28.25%) individuals between 9 (9/601, 1.5%) and 122 (122/601, 20.3%) households. The most entries (470) were made by data collector 5. Only 2 respondents had data entry errors (2/1706, 0.12%). However, 73 (73/601, 12.1%) households had inaccurate date and time entries for when data collection started and ended. The cost of deploying ODK was estimated at US $206.7 in comparison with the estimated cost of US $466.7 for paper-based data management. CONCLUSIONS: We found the use of mobile data capture technology to be efficient and cost-effective. As Internet services improve in Africa, we advocate their use as effective tools for health information management.

Stroke survivors in Nigeria: A door-to-door prevalence survey from the Niger Delta region.

The burden of stroke has been projected to increase in low-and middle-income countries due to the ongoing epidemiological transition. However, community-based stroke prevalence studies are sparse in sub-Saharan Africa particularly in Nigeria. This study aimed to provide a comparative estimate of the prevalence of stroke survivors in the rural Niger Delta region. A three-phased door-to-door survey was conducted using WHO modified instruments. In the first-phase, 2028 adults (≥18years) participants randomly selected from two rural communities were screened by trained health research assistants for probable stroke. In the second phase, suspected cases were screened with stroke-specific tool. Positive cases were made to undergo complete neurological evaluation by two study neurologist in phase-three. Stroke diagnosis was based on clinical evaluation using WHO criteria. Overall, 27 (8 first-ever and 19 recurrent cases) stroke survivors with crude prevalence of 13.31/1000 (95% CI, 8.32-18.31) and a non-significant difference in prevalence between the two study communities were found, (P=0.393I). In addition, age-adjusted prevalence of stroke survivors was 14.6/1000 person, about 7-folds higher than previous estimates outside the Niger Delta region. The prevalence increases significantly with advancing in age, P<0·001. Among others, hypertension (92.59%) was the commonest risk factor and comorbidity found. Improved stroke surveillance and care, as well as better management of the underlying risk factors, primarily undetected or uncontrolled high blood pressure, remains a public health priority.
