Chronic obstructive pulmonary disease in East Africa: a systematic review and meta-analysis.

Chronic obstructive pulmonary disease (COPD) is a common lung disease that causes restricted airflow and breathing problems. Globally, COPD is the third leading cause of death and low- and middle-income countries account for the majority of these deaths. There is limited information on COPD's prevalence in East Africa. Thus the purpose of this systematic review and meta-analysis is to estimate the pooled prevalence of COPD in East Africa.A computerized systematic search using multiple databases was performed in search of relevant English articles from the inception of the databases to August 2023. All the authors independently extracted the data. R and RStudio software were used for statistical analysis. Forest plots and tables were used to represent the data. The statistical heterogeneity was evaluated using I2 statistics. There was heterogeneity between the included articles. Therefore, a meta-analysis of random effects models was used to estimate the overall pooled prevalence of COPD in East Africa. A funnel plot test was used to examine possible publication bias.The database search produced 512 papers. After checking for inclusion and exclusion criteria, 43 full-text observational studies with 68 553 total participants were found suitable for the review. The overall pooled prevalence of COPD in East Africa was 13.322%. The subgroup analysis found the COPD pooled prevalence in the different countries was 18.994%, 7%, 15.745%, 9.032%, 15.026% and 11.266% in Ethiopia, Uganda, Tanzania, Malawi, Sudan, and Kenya, respectively. Additionally, the subgroup analysis of COPD by study setting among community-based studies was 12.132% and 13.575% for hospital-based studies.According to the study's findings, approximately one of every seven individuals in East Africa has COPD, indicating a notably high prevalence of the disease. Thus governments and other stakeholders working on non-communicable disease control should place an emphasis on preventive measures to minimize the burden of COPD.

Prevalence of hypertension among type 2 diabetes mellitus patients in Ethiopia: a systematic review and meta-analysis.

BACKGROUND: Hypertension among diabetic patients is a worldwide public health challenge and a leading modifiable risk factor for other cardiovascular diseases and death. This study aimed to estimate the prevalence of hypertension among diabetic patients in Ethiopia. METHODS: The studies were selected using PubMed, Embase, Health InterNetwork Access to Research Initiative and Cochrane Library databases and Google searches. Two independent authors carried out the data extraction using a predetermined and structured method of data collection. R version 3.5.3 and RStudio version 1.2.5003 were used for analysing the data. To assess possible publication bias, funnel plot test methods were used. The guidelines of the Preferred Reporting Items for Systematic Reviews and Meta-Analyses were used to publish the results. This study was registered in the Prospective Register Systematic Reviews (CRD42020170649). RESULTS: A total of 218 articles were identified but only 6 six full-text abstract papers were included in this systematic review and meta-analysis. The random effects model analysis showed that the pooled prevalence of hypertension among type 2 diabetes mellitus (DM) patients in Ethiopia was 55% (95% confidence interval [CI] 49 to 61). The subgroup analysis of the pooled prevalence of hypertension among type 2 DM patients in the Oromia and Southern regions was 51% (95% CI 42 to 59) and 58% (95% CI 54 to 63), respectively. The pooled prevalence of hypertension among type 2 DM patients was higher among urban residents (60% [95% CI 54 to 67] and 52% [95% CI 41 to 63] among urban and rural residents, respectively). CONCLUSIONS: This study showed a high pooled prevalence of hypertension among type 2 DM patients in Ethiopia. Appropriate preventive measures should be implemented to reduce the burden of hypertension among DM patients in Ethiopia.

Self-care practice among hypertensive patients in Ethiopia: systematic review and meta-analysis.

BACKGROUND: In high-income and low-income countries, including Ethiopia, hypertension (HTN) is a serious public health concern. As a consequence, a massive self-care practice (SCP) is necessary, and the domains of SCP, including adherence to medication, physical activity, weight management, low-salt diet, non-smoking, moderate alcohol usage, and dietary management, are required. However, there is no nationwide study on HTN SCPs in Ethiopia. This meta-analysis, therefore, aimed to estimate the pooled level of HCP among individuals living with HTN in Ethiopia. METHODS: The Preferred Reporting Items for Systematic Reviews and Meta-Analysis guideline was used to report this systematic review and meta-analysis. We systematically searched the databases PubMed/MEDLINE, Embase, Google Scholar and Science Direct for studies conducted in Ethiopia. All observational studies published until July 2020 were included. Data were analysed using R V.3.5.3 software, and the pooled prevalence with 95% CIs was presented using tables and forest plots. The presence of statistical heterogeneity (I2) within the included studies was evaluated. We used a funnel plot to identify evidence of publication bias. The random-effects meta-analysis model was employed to estimate the pooled proportion of good HTN SCPs.This was submitted for registration with the International Prospective Register of Systematic Reviews in March 2020 and accepted with the registration number CRD42020175743 (https://www.crd.york.ac.uk/PROSPERO). RESULTS: Our search databases produced 356 papers. Twelve of these papers fulfilled the inclusion and were found suitable for the review. The total population in this study was 3938. Off these hypertensive populations, 44% (95% CI 34 to 53) had good SCP. The subgroup analysis for each component of SCP was done. The subgroup analysis of good adherence to low-salt diet, alcohol abstinence, medication adherence, non-smoking, physical exercise and weight management was 52% (95% CI 39% to 66%), 77% (95% CI 69% to 88%), 65% (95% CI 45% to 85%), 92% (95% CI 88% to 95%), 43% (95% CI 30% to 56%) and 51% (95% CI 32% to 69%), respectively. In conclusion, nearly half of patients with HTN had good SCPs.

Diabetic Peripheral Neuropathy in Ethiopia: A Systematic Review and Meta-Analysis.

BACKGROUND: Currently, diabetic peripheral neuropathy (DPN) is one of the most severe complications of diabetes mellitus (DM). Despite the seriousness of this problem, limited evidence is available on the prevalence of diabetic peripheral neuropathy among patients with diabetes mellitus in Ethiopia. In Ethiopia, there were no updated studies that estimate the national prevalence of DPN. Hence, this systematic review and meta-analysis provided a national prevalence of diabetic peripheral neuropathy among patients with diabetes mellitus in Ethiopia. METHODS: This study was submitted for registration with the International Prospective Register of Systematic Reviews (PROSPERO) in March 2020 and accepted with the registration number CRD42020173831. Different database searching engines were searched online to retrieve related articles, including PubMed, Scopus, Google Scholar, African Journals Online, World Health Organization (WHO) Afro Library, and Cochrane Review. The reviewers used the Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) guideline in the reviewing process. In this systematic review and meta-analysis, all published and unpublished articles were analyzed. The reviewers used the random effects model to estimate the pooled prevalence of diabetic peripheral neuropathy among diabetes mellitus patients. The reviewers conducted the statistical analysis using the R version 3.5.3 and RStudio version 1.2.5033 software for Windows. The reviewers evaluated the heterogeneity across the included studies by the inconsistency index (I 2). The reviewers examined the publication bias by the funnel plot. RESULTS: The search of the databases produced 245 papers. After checking the inclusion and exclusion criteria, 38 articles with 14029 total patients with diabetes mellitus were found suitable for the review. Except for three (retrospective cohort study), all studies were cross-sectional. The overall pooled prevalence of diabetic peripheral neuropathy was 22% (95% CI 18% to 26%). The subgroup analysis of diabetic peripheral neuropathy among patients with diabetes in the different regions was 23% (95% CI 17% to 29%) in Addis Ababa, 27% (95% CI 16% to 38%) in Oromia, 16% (95% CI 14% to 18%) in South nation and nationalities, and 15% (95% CI 6% to 24%) in Amhara. CONCLUSIONS: More than one-fifth of patients with diabetes have diabetic peripheral neuropathy. According to this study, the prevalence of diabetic peripheral neuropathy in Ethiopia is considerably high. This evidence suggests that attention should be given to patients with diabetes in monitoring patients' blood glucose.

The outcome of COVID-19 among the geriatric age group in African countries: protocol for a systematic review and meta-analysis.

BACKGROUND: According to the World Health Organization (WHO), the outbreak of coronavirus disease in 2019 (COVID-19) has been declared as a pandemic and public health emergency that infected more than 5 million people worldwide at the time of writing this protocol. Strong evidence for the outcome of COVID-19 among the geriatric age group has not been published in Africa. Therefore, this protocol will be served as a guideline to conduct a systematic review and meta-analysis of the outcome of COVID-19 among the geriatric age group in Africa. METHODS: Published and unpublished studies on the outcome of COVID-19 among the geriatric age group in Africa and written in any language will be included. Databases (PubMed / MEDLINE, Google Scholar, Google, EMBASE, Web of Science, Microsoft Academic, WHO COVID-19 database, Cochran Library, Africa Wide Knowledge, and Africa Index Medicus) from March to August 2020 will be searched. Two independent reviewers will select, screen, extract data, and assess the risk of bias. The proportion will be measured using a random-effects model. Subgroup analysis will be conducted to manage heterogeneity. The presence of publication bias will be assessed using Egger's test and visual inspection of the funnel plots. This systematic and meta-analysis review protocol will be reported per the PRISMA-P guidelines. CONCLUSION: This systematic review and meta-analysis protocol will be expected to quantify the outcome of COVID-19 among the geriatric age group in Africa. SYSTEMATIC REVIEW REGISTRATION: This protocol was submitted for registration with the International Prospective Register of Systematic Reviews (PROSPERO) in April 2020 and accepted with the registration number: (https://www.crd.york.ac.uk/PROSPERO).

Intimate partner violence against reproductive age women during COVID-19 pandemic in northern Ethiopia 2020: a community-based cross-sectional study.

BACKGROUND: As the global pandemic of corona virus (COVID-19) spreads across continents and communities, people are forced to respond with strict preventive measures such as staying at home and keeping social distance. In relation with these measures, particularly with the staying at home, increasing rates of domestic violence are beginning to surface. Hence, this study was aimed at determining the prevalence of intimate partner violence against reproductive age women in northern Ethiopia during the COVID-19 pandemic. METHODS: A community-based cross-sectional study design was employed. The data were collected during the period of April to May, 2020 using interviews and a self-administered standard questionnaire. The data were entered into the Epi-data manager version 4.2 and exported to SPSS 22 for analysis. The descriptive analysis such as frequency distribution, percentage, and measures of central tendency were used. This was followed by binary and multiple logistic regression analysis to infer the association between the outcome and independent variables. RESULTS: A total of 682 participants were included in the study. The prevalence of intimate partner violence against women was found to stood at 24.6% with psychological violence being the most prevalent (13.3%), followed by physical (8.3%) and sexual violence (5.3%). Women were more likely to suffer from violence if they were housewives (AOR, 95% CI (18.062 (10.088, 32.342))), age less than 30 (AOR, 95% CI (23.045 (5.627, 94.377))), women with arrange marriage (AOR, 95% CI (2.535 (1.572, 4.087))) and women with husband's age being "between" 31-40 (AOR, CI 95% (2.212 (1.024, 4.777))). CONCLUSIONS: This study showed the presence of a relatively high prevalence of intimate partner violence against women. Thus, public reporting of any cases or concerns of abuse is critical and vital to mitigate the problem.

Prescribing Pattern of Antibiotics Using WHO Prescribing Indicators Among Inpatients in Ethiopia: A Need for Antibiotic Stewardship Program.

BACKGROUND: Irrational prescribing of antibiotics is a universal public health problem, leading to antibiotic resistance. Understanding the prescribing pattern of antibiotics is crucial to tackling irrational prescription. Yet, comprehensive studies regarding the prescribing pattern of antibiotics among inpatients and the need for an Antibiotic Stewardship Program (ASP) are lacking in Ethiopia. This study aimed to evaluate prescribing patterns of antibiotics and the need for an ASP. METHODS: A hospital-based prospective observational study was carried out from February 2019 to December 2019. This study was conducted among patients admitted to Aksum University Comprehensive Specialized Hospital, Ethiopia. Data were collected using a data abstraction format generated by World Health Organization (WHO) prescribing indicators. Data analysis was carried out using SPSS version 25.0. RESULTS: A total of 1653 antibiotics were prescribed for 822 inpatients. Overall, 52.3% of patients had at least one oral and/or injectable antibiotic prescribed, for a mean duration of 4.2 (SD=2.3) days. The average number of prescribed antibiotics per patient was 2.01 (SD=1.9). The majority (97.6%) of antibiotics were prescribed by their generic name, and all prescribed antibiotics were from the national Essential Medicine List (EML). Frequently prescribed injectable and oral antibiotics were ceftriaxone (24.5%) and azithromycin (12.9%), respectively. Culture and sensitivity testing were not performed in any of the cases. During the study period, 65.2% of key antibiotics were available in stock. CONCLUSION: In this study, more than half of patients were on at least one antibiotic, and all antibiotics were prescribed from the national EML. However, all antibiotics were prescribed empirically. This result shows that the prescribing pattern of antibiotics in the hospital deviates from and is non-compliant with the standard endorsed by WHO. This study provides evidence for the necessity and a way forward for the establishment of an ASP in the hospital that may help to introduce the prescribing of antibiotics with the aid of culture and sensitivity tests, and to develop institutional guidelines.

Seroprevalence of Hepatitis B Virus Infection, Mother-To-Child Transmission, and Associated Risk Factors Among Delivering Mothers in Tigray Region, Northern Ethiopia: a Cross-Sectional Study.

INTRODUCTION: High prevalence of hepatitis B virus (HBV) infection among pregnant women is the primary source of infection for their children and the general population. Mother-to-child transmission (MTCT) is the primary mode of transmission in endemic areas like Ethiopia. The aim of this study was to determine the prevalence of HBV infection, rate of MTCT, and associated risk factors among delivering mothers. METHODS: This health facility-based cross-sectional study was conducted in four public hospitals of the Eastern zone of Tigray among 473 delivering mothers. Structured questionnaires and laboratory results were used to collect the data. The data were checked for completeness and entered into EpiData manager version 4.6.0.0. Then the data were exported to Statistical Package for Social Sciences (SPSS) version 23. The odds ratio, along with a 95% confidence interval, was estimated to identify predictors of HBV infection using multivariable logistic regression analysis. Significant association was considered at p < 0.05. RESULTS: A total of 473 mothers were enrolled, and the response rate was 100%. The prevalence of HBV infection among the mothers and the rate of MTCT of the infection were 11.6% and 30.9%, respectively. History of home delivery [adjusted odds ratio (AOR) = 4.5, 95% confidence interval (CI) (2, 10.6)], history of hospital admission [AOR = 5, 95% CI (2.2, 11.5)], working at health facility [AOR = 5.4, 95% CI (1.4, 20.7)], body tattoos [AOR = 5.8, 95% CI (2.4, 13.6)], sharing personal care materials [AOR = 3.8, 95% CI (1.4, 9.9)], insufficient knowledge [AOR = 5.6, 95% CI (1.6, 19)], and having human immunodeficiency virus (HIV) [AOR = 5.1, 95% CI (1, 26.2)] were significantly associated with HBV infection. CONCLUSION: HBV infection among delivering women is becoming highly endemic, and the rate of MTCT was high. Therefore, administering hepatitis B vaccine to all neonates within 24 h of birth is mandatory to prevent MTCT of HBV infection and related complications. Furthermore, health education and dissemination of information about HBV for the pregnant mothers are needed to reduce HBV infection and vertical transmission in Ethiopia.

Determinants of Acute Asthma Attack among adult asthmatic patients visiting hospitals of Tigray, Ethiopia, 2019: case control study.

INTRODUCTION: Acute asthma attack is one of the most common causes of visits to hospital emergency departments in all age groups of the population and accounts for the greater part of healthcare burden from the disease. Despite, Acute asthma attack is an important public health problem that affects not only the patients, but also to the family, health professionals, health care institutions and development of the nation, little is known about the risk factors of acute asthma attack.Therefore, this study is aimed to investigate the determinants of acute asthma attack among. OBJECTIVE: The aim of this study was to assess the determinant factors of acute asthma attack among adult asthmatic patients visiting general hospitals of central zone, Tigray, Ethiopia, 2019. METHOD: Hospital based unmatched case control study design was conducted in general hospitals of central zone of Tigray, Ethiopia 2019. Data were collected using pretested interviewer administered questionnaire. A total of 289 study subjects (96 cases &193 controls) were selected by systematic random sampling. Data were entered to Epi data version 3.1 then exported to SPSS version 23 for analysis. Bivariate logistic regression was employed to examine the statistical association between dependent and independent variables. Variables with p value < 0.25 in binary logistic regression were entered to multivariable logistic regression model and variables with p value < 0.05 was taken as significant determinants of the outcome variable. RESULT: A total of 96 adult asthmatic patients who have acute asthma attack (cases) and 193 adult asthmatic patients without attack (controls)) with 100% response rate were participated in this study. Upper Respiratory tract Infection [AOR = 6.835,95% CI = 3.285,14.222], Season [AOR =2.204,95% CI = 1.011,4.805] kitchen smoke [AOR = 2.307,95%CI1.010,5.272]& sleep apnea [AOR = 9.254, 5%CI =3.563,25.460] were significantly associated with acute asthma exacerbation.

Uncontrolled asthma in Ethiopia: a systematic review and meta-analysis.

INTRODUCTION: Despite significant improvement in the diagnosis and management of this disorder, asthma in the majority of Ethiopians remains poorly controlled. Although the prevalence of uncontrolled asthma is a public health problem in Ethiopia, its reported prevalence varies from study to study. Hence, this review aims to determine the true prevalence of uncontrolled asthma among asthmatic patients in Ethiopia. MATERIAL AND METHODS: Different database searching engines were used including PubMed, Scopus, Google Scholar, Africa journal online, World Health Organization (WHO) afro library, and Cochrane review. They were systematically searched for published studies on uncontrolled asthma in Ethiopia from 2014 to 2019. Primary search terms were "asthma", "uncontrolled asthma", "uncontrolled wheezing", and "Ethiopia". The Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) guideline was followed. Publication bias was examined by the funnel plot. The random-effect model was fitted to estimate the pooled prevalence of uncontrolled asthma among asthmatic patients. All statistical analysis was done using R version 3.5.3 and the RStudio version 1.2.5033 software for Windows. RESULTS: The overall pooled prevalence of uncontrolled asthma was found to be 71.67% [95% CI (0.6772; 0.7562)]. Potential associated factors were: unscheduled visits, frequency of short-acting beta2-agonist (SABA) use, type of treatment and perceived rate of asthma control, low monthly income, age group, presence of comorbidity, moderate persistent asthma, severe persistent asthma and use of SABA alone as anti-asthmatic medication, use of biomass fuel for cooking, longer duration of asthma (> 30 years), incorrect inhalation technique, and asthma exacerbation in the last 12 months. Self-perceived poor asthma control was associated with any activity limitation due to asthma, inconsistent inhaled corticosteroid use, and lack of health education on metered-dose inhaler technique [AOR =4.96; 95% CI (1.08-22.89)]. CONCLUSIONS: Nearly two-thirds of patients were determined to have uncontrolled asthma. Thus, this evidence suggests that attention should be given to asthma patients and health care providers.
