Compliance with infection prevention and control standard precautions and factors associated with noncompliance among healthcare workers working in public hospitals in Addis Ababa, Ethiopia.

BACKGROUND: Standard Precautions (SPs) are the minimal infection prevention and control (IPC) measures that apply to all patient care activities at all times, regardless of whether the patient has a suspected or proven disease, in any place where healthcare service is provided. These evidence-based practices protect healthcare workers (HCWs) from infection while preventing the spread of infectious agents among patients, visitors, and the environment. OBJECTIVES: Assessed compliance of HCWs working in public hospitals in Addis Ababa to infection prevention and control SPs, and factors associated with noncompliance. METHODS: In a hospital-based cross-sectional study, 422 HCWs were recruited from nine public hospitals in Addis Ababa using a stratified random sampling technique. Data were collected using self-administered questionnaires, entered into a computer using Epi data, and analyzed using SPSS version 25. The association between the independent and the outcome variables was investigated using logistic regression. Odd ratios with corresponding 95% confidence intervals (CI) were used as measures of the strength of the association between the outcome and the explanatory variables. A p-value below 5% was considered an indicator of statistical significance. RESULTS: The level of knowledge of HCWs about IPC and SPs was 51.9% and 36.49% of the respondents were compliant with SPs. Receiving IPC Training [Adjusted Odds Ratio (AOR) = 1.81, 95% CI 1.06, 3.09], knowing SPs [AOR = 3.46, 95% CI = 1.83, 6.54], presence of a mechanism in the hospital to enforce the IPC practices [AOR = 1.71 95% CI = 1.01, 2.89], and availability of cleaning and disinfection chemicals in the hospital [AOR = 2.18, 95%CI = 1.15, 4.13] were significantly associated with the HCWs' compliance with SPs. CONCLUSION: Compliance with IPC standard precautions of HCWs in public hospitals of Addis Ababa is suboptimal. Working in medical units, less work experience, lack of training, poor knowledge, absence of a mechanism to enforce adherence, and inadequate resources are independent predictors for non-compliance of the HCWs.

Effects of sedatives on radiologic enema reduction in children with ileocolic intussusception: A systematic review and meta-analysis.

BACKGROUND: In children with ileocolic intussusception, sedatives such as midazolam, ketamine and propofol may facilitate radiologic enema reduction, but studies on their separate and joint effects remain controversial. OBJECTIVES: We aimed to systematically analyze studies for the effects of sedatives on the radiologic reduction of ileocolic intussusception in children. METHODS: We searched PubMed, EMBASE, CINAHL, Scopus and Web of Science from database inception through March 2023 for articles that enrolled children with ileocolic intussusception who underwent non-operative pneumatic or hydrostatic enema reduction under ultrasound or fluoroscopic guidance with or without the use of sedatives. The primary and secondary outcomes were success rate in radiologic reduction of ileocolic intussusception and risk of perforation, respectively. Effect estimates from the individual studies were extracted and combined using the Hartung-Knapp-Sidik-Jonkman log-odds random-effects model. Heterogeneity between studies was checked using Cochran's Q test and the I2 statistic. RESULTS: A total of 17 studies with 2094 participants were included in the final review, of which 15 were included in the meta-analysis. Nine studies reported on the success rate of radiologic reduction performed under sedation in all participants, while six studies compared the success rate in two patient groups undergoing the procedure with or without sedation. The pooled success rate of non-operative reduction under sedation was 87 % (95 % CI: 80-95 %), P = 0.000 with considerable heterogeneity (I2 = 85 %). A higher success rate of 94 % (95 % CI: 88-99 %) and homogeneity (I2 = 12 %) were found in studies with pneumatic enema reduction. Among comparative studies, the odds of success of non-operative reduction were increased when the procedure was performed under sedation, with a pooled odds ratio of 2.41 (95 % CI: 1.27-4.57), P = 0.010 and moderate heterogeneity (I2 = 60 %). In a sensitivity analysis, homogeneity was found between analyzed studies when two outliers were excluded (I2 = 0.73 %). The risk of perforation was not significantly different (OR 1.52, 95 % CI: 0.09-23.34), P = 0.764 indicating small study effects. No publication, bias was detected on visual inspection of the funnel plots or the Begg's and Egger's bias tests. Most studies were categorized as having a low risk of bias using Joanna Briggs Institute checklists. CONCLUSIONS: In selected patient groups, sedation can increase the success rate of radiologic enema reduction in children with ileocolic intussusception without evidence of increased risk of perforation.

Chest X-ray predicts cases of pulmonary tuberculosis among women of reproductive age with acute respiratory symptoms: A multi-center cross-sectional study.

Background: Tuberculosis (TB) prevalence is increasing among women of reproductive age (WRA) in sub-Saharan Africa, yet undiagnosed and untreated cases remain rather high with serious health and socio-economic consequences. We aimed to assess the prevalence and predictors of TB in WRA seeking health care for acute respiratory symptoms. Methods: We consecutively enrolled outpatient WRA with acute respiratory symptoms seeking care at four healthcare facilities in Ethiopia between July 2019 and December 2020. Data on sociodemographic characteristics and clinical information were collected using a structured questionnaire administered by trained nurses. Posteroanterior chest X-ray was performed in non-pregnant WRA and interpreted independently by two radiologists. Sputum samples were collected from all patients and tested for pulmonary TB using Xpert MTB/RIF and/or smear microscopy. Predictors of bacteriologically confirmed TB cases were determined using binary logistic regression, with clinically relevant variables included in the final Firth's multivariate-penalized logistic regression model. Results: We enrolled 577 participants, of whom 95 (16%) were pregnant, 67 (12%) were living with HIV, 512 (89%) had cough of less than 2 weeks, and 56 (12%) had chest-x-ray findings suggestive of TB. The Overall prevalence of TB was 3% (95% CI: 1.8%-4.7%) with no significant difference observed between patient groups categorized by duration of cough or HIV serostatus (P-value = 0.9999). In multivariable analysis, TB-suggestive CXR abnormality (AOR 18.83 [95% CI, 6.20-57.18]) and history of weight loss (AOR 3.91 [95% CI, 1.25-12.29]) were associated with bacteriologically-confirmed TB cases. Conclusions: We found a high TB prevalence among low-risk women of reproductive age with acute respiratory symptoms. Routine CXR may improve early case detection and thereby TB treatment outcomes.

The Quality of Logistics Management Information System and the Availability of Tracer Drugs at Health Posts in Rural Ethiopia: A Mixed-Method Study.

Background: Proper implementation of the logistics management information system (LMIS) would facilitate access to essential pharmaceutical products. It also prevents wastage at health posts. The aim of this study was to assess the implementation of the LMIS and the availability of tracer drugs at health posts in rural Ethiopia. Methods: We employed a cross-sectional descriptive design with a mixed-method approach. The data used for this paper was collected from March to May 2019 as part of the National HEP assessment. The study involved 343 health posts randomly selected from nine regions of Ethiopia. Women's Development Army members and household heads participated in the qualitative study (i.e. in FGD and KII). The quantitative data were exported from Open Data Kit (ODK) to Stata 15.1 for statistical analysis, and the qualitative data were entered into NVivo 12 and analyzed using thematic content analysis. Results: Of the health posts, 59.4% had a space for storing drugs; less than half (41.9%; 95% confidence interval (CI) [36%, 48%]) had a functioning refrigerator. The mean percentage of the availability of selected tracer drugs at health posts was 59.6%, with a 95% CI (58.9%, 60.3%). Bin cards were available at 43% (95% CI [40%, 46%]) of health posts, and among these, only 27.5% of the health posts adequately used the bin cards. Conclusion: The absence and poor use of LMIS tools was observed at health posts. Proper implementation of the LMIS has the potential to improve the availability of essential drugs that, in turn, improve health post level delivery of health services.

Comparative efficacy and safety of anti-infective drugs for patients with mild to severe COVID-19: A systematic review and network meta-analysis of randomized controlled trials.

Background: Different anti-infective drugs have been proposed for the treatment of patients with COVID-19. We carried out a network meta-analysis to assess their relative efficacy and safety. Methods: We searched relevant databases for all randomized controlled trials that reported the efficacy and or safety of any anti-infective drugs published up to April 30, 2022 for different outcomes. We did both pairwise and network meta-analysis with 95% confidence intervals using a fixed-effect model. We assessed studies for quality of evidence using an extension of the standard Grading of Recommendations, Assessment, Development and Evaluation approach considering P<0.05 to be statistically significant. Results: We included 68 RCTs for 27,680 participants on 22 anti-infective drugs. For clinical recovery at 14 days Ivermectin (OR= 3.00, 95%CI: [1.82; 4.96]; p < 0.0001; moderate certainty evidence), Baricitinib plus Remdesivir (OR= 2.20, 95%CI: [1.35; 3.53]; p = 0.005; low certainty evidence), and Favipiravir (OR= 2.16, 95%CI: [1.27; 3.68]; p = 0.004; moderate certainty evidence) were statistically effective than standard of care. There was no statistically significant difference between treatments for the viral clearance at 14 days outcome and standard of care. In terms of death outcome, only combined therapy of Baricitinib and Remdesivir showed statistically significant risks of ratio (RR= 0.47, 95%CI: [0.23; 0.99]; p = 0.03). Arbidol (RR= 0.46, 95% CI: [0.23; 0.95]; p = 0.04) was statistically safe drug than standard of care. Conclusion: This Network Meta-analysis suggests that Baricitinib plus Remdesivir is more effective than the other anti-infective drugs in treating patients with COVID-19 in terms of clinical recovery at 14 days, mortality and adverse events outcomes.

Insecticidal effects of some selected plant extracts against Anopheles stephensi (Culicidae: Diptera).

BACKGROUND: The use of synthetic insecticides against mosquitoes may lead to resistance development and potential health hazards in humans and the environment. Consequently, a paradigm needs to shift towards the alternative use of botanical insecticides that could strengthen an insecticide resistance management programme. This study aimed to assess the insecticidal effects aqueous, hexane, and methanol crude leaf extracts of Calpurnia aurea, Momordica foetida, and Zehneria scabra on an insectary colony of Anopheles stephensi larvae and adults. METHODS: Fresh leaves of C. aurea, M. foetida and Z. scabra were collected and dried, then separately ground to powder. Powdered leaves of test plants were extracted using sonication with aqueous, hexane, and methanol solvents. The extracts were concentrated, and a stock solution was prepared. For comparison, Temephos (Abate®) and control solutions (a mixture of water and emulsifier) were used as the positive and negative controls, respectively. Different test concentrations for the larvae and the adults were prepared and tested according to WHO (2005) and CDC (2010) guidelines to determine lethal concentration (LC) values. Mortality was observed after 24 h exposure. The statistical analyses were performed using Statistical Package for the Social Sciences (SPSS) software (Kruskal-Wallis test) and R software (a generalized linear model was used to determine LC50 and LC90 values of the extracts). RESULTS: The lowest LC50 values were observed in aqueous extracts of M. foetida followed by Z. scabra extract and C. aurea leaves at 34.61, 35.85, and 38.69 ppm, respectively, against the larvae. Larval mortality was not observed from the hexane extracts and negative control, while the standard larvicide (temephos) achieved 100% mortality. Further, the adulticidal efficacy was greatest for aqueous extract of Z. scabra with LC50 = 176.20 ppm followed by aqueous extract of C. aurea (LC50 = 297.75 ppm). CONCLUSION: The results suggest that the leaf extracts of the three test plants have the potential of being used for the control of vector An. stephensi larvae and adult instead of synthetic mosquitocides. Further studies need to be conducted to identify the active ingredients and their mode of action.

Woody species composition and community types of Hangadi Watershed, Guji Zone, Ethiopia.

BACKGROUND: Hangadi watershed is endowed with the only virgin forest in Odo shakisso harbouring high biodiversity, but it has been suffered from anthropogenic activities. This study was conducted to investigate composition and community diversity of woody species in restoration for posterity. Satellite images of 1988, 2008, and 2018 were used to classify and analyse trends of deforestation. For both woody species and topsoil (0-30 cm), 20 m × 20 m, 100 plots laid at every 300 m along line transects, 1 km apart from each other. In each sample plot, woody species ≥ 3 m were counted, Shannon-wiener diversity index, cluster analysis and ordination were computed. RESULTS: Agroforestry is found to be the dominant land use/land cover class followed by forest and cultivated land. A total of 61 woody species belonging to 34 families; 8.2% of the species were endemic to Ethiopia. The highest number of species was recorded from families Euphorbiaceae and Rubiaceae (5 species, 8.2%), Rutaceae, Celastraceae, and Oleaceae (3 species, 5.08%) followed by Flacourtiaceae, Meliaceae, Araliaceaae, Myrsinaceae, Moraceae, Boraginaceae, Asteraceae, Spontaceae, Lauraceae and Sapindaceae (2 species each). Four woody plant communities were identified using free statistical software R version 3.1.1. The canonical correspondence analysis result showed that EC, pH, OM, altitude, C:N, CEC, sand, silt, AvP, and TN significantly affected species distribution in the watershed. CONCLUSION: Local people involved in cutting mature woody species for timber production, making farm implements and, cultivated land expansion. Protection of woody species diversity of forest and coffee systems with low biodiversity value conservation concepts are recommended to be executed jointly by local people and stakeholders.

HIV voluntary counseling and testing uptake and associated factors among Ethiopian youths: evidence from the 2016 EDHS using multilevel modeling.

BACKGROUND: Existing evidence showed that Human Immunodeficiency Virus counselling and testing uptake among Ethiopian youths is low, and factors contributing to it are not well studied. Therefore, this study aims to assess the status of uptake and identify its determinants using the 2016 Ethiopia Demographic and Health Survey data. METHOD: Data of 10,903 Ethiopian youths were extracted from the 2016 Ethiopian Demographic and Health Survey. The association between the response variable and the predictors was modeled by multilevel binary logistic regression, whereas adjusted odds ratio and confidence intervals were used to measure associations and their statistical significance. The variation in the uptake of counselling and testing of HIV across regions of Ethiopia was quantified by intra-class correlation. RESULT: The current study revealed that, overall, 34.9% (95% CI: 33.5, 36.2%) Ethiopian youths were ever tested for human immunodeficiency virus. Results show that about 9% of the variation in the probability of being tested for the disease was due to the regional variations. Moreover, having moderate and comprehensive HIV knowledge, being rich, having risky sexual behaviour, having a better educational level, having professional work, being married, owning of mobile, and having access to media were positively associated with human immunodeficiency virus voluntary counselling and testing uptake. On the other hand, being male, following protestant religion, following Muslim religion, and following other religions than orthodox religion were negatively associated with the uptake of human immunodeficiency virus counselling and testing. CONCLUSION: Voluntary human immunodeficiency virus counselling and testing uptake among Ethiopian youths is very low and varies across the regions which might hamper the ambitious plan of Ethiopia to end the disease as a public health threat by 2030. Emphasis should be given to promoting the youths' HIV-related knowledge through community-based education, encouraging and empowering the youths to participate in professional works by giving due focus to poor youths, and promoting mass media utilization to better achieve the plan.

HIV Voluntary Counseling and Testing Uptake and Associated Factors Among Sexually Active Men in Ethiopia: Analysis of the 2016 Ethiopian Demographic and Health Survey Data.

BACKGROUND: Human immuno-deficiency virus (HIV) counseling affirms that people exercise the right to know their HIV status, which opens the gateway to care, treatment, and support for a person in need. HIV counseling and testing uptake among sexually active males in Ethiopia is too low. Moreover, existing studies were not done at country level and the contributing factors were not well studied. Therefore, the aim of this study is to determine the status of uptake and identify its correlates using the 2016 Ethiopia Demographic and Health Survey. METHODS: Data on 12,688 participants were utilized in this study. Descriptive statistics and multilevel logistic regression were used to summarize the data and investigate the associations between predictors and HIV counseling and testing uptake. RESULTS: The overall HIV voluntary counseling and testing uptake among sexually active men in Ethiopia was 45.69%; 95% CI [43.08%, 48.33%]. About 13% of the variation in the likelihood of being tested for HIV was due to the variation among the regions. On the other hand, age, religion, education, occupation, marital status, HIV knowledge, health insurance coverage, wealth status, risky sexual behavior, family planning discussion with health workers, owning a mobile, frequency of watching television, and listening to the radio were significantly associated with the uptake of HIV voluntary counseling and testing. CONCLUSION: HIV voluntary counseling and testing uptake in Ethiopia is still low and varies across the regions, which might hamper the ambitious plan of Ethiopia to end AIDS as a public health threat by 2030. Therefore, giving due consideration to scale up HIV knowledge to avoid risky sexual behavior, improving access to health insurance and media, and working on the significant modifiable sociodemographic determinants are worthy to boost HIV voluntary counselling and testing uptake, which is an integral component of the strategies to efficiently prevent and control HIV.
