Smear positive tuberculosis and genetic diversity of M. tuberculosis isolates in individuals visiting health facilities in South Gondar Zone, northwest Ethiopia.

ABSTRACT: BACKGROUND:Tuberculosis (TB), a bacterial infectious disease, continues to be a public health concern in many developing countries. However, lack of data concerning the public health burden and potential risk factors for the disease hampers control programs in target areas. Therefore, the aims of present study were to determine the prevalence of TB and genetic diversity of M. tuberculosis isolates from individuals visiting health facilities in South Gondar Zone, northwest Ethiopia. METHODS:A cross-sectonal study was conducted between March 2015 and April 2017. Bacteriological examination, region of difference (RD) 9 based polymerase chain reaction (PCR) and spoligotyping were used. RESULTS:The overall prevalence of all smear positive TB was 6.3% (186/2953). Extra pulmonary TB (EPTB) was clinically characterized in about 62.4% (116/186) TB-positive cases. Some demographic characteristics, such as patients' origin (districts where patients were recruited) [patients' origin (chi-square (?2) value; 62.8,p<0.001) were found to be significantly associated risk factors for the occurrence of TB in the study area. All the mycobacterial isolates were found to be M. tuberculosis. Among the 35 different spoligotype patterns identified, 22 patterns were shared types.The three dominantly identified families were T, CAS and Manu, each consisting of 46.9%, 24.0% and 10.4% of the isolates, respectively. CONCLUSION:The present study revealed that TB continues to be a public health problem in South Gondar Zone which suggests a need of implementing effective disease control strategies.

Project description:BackgroundSputum smear conversion is a key indicator of treatment response and reduced infectivity among bacteriologically confirmed pulmonary tuberculosis (PTB) patients. This study aimed at estimating sputum smear conversion and identifying factors hindering sputum smear conversion among bacteriologically confirmed PTB cases in East Gojjam Zone, Northwest Ethiopia.MethodsA total of 282 bacteriologically confirmed PTB patients were followed for 22 weeks through weekly sputum smear examination. Due to the absence of sputum culture and rapid diagnostic services, sputum smear conversion evaluation was conducted microscopically using acid-fast-bacilli staining technique of sediments from a 5% sodium hypochlorite concentration technique. Data on socio-demographic, clinical profile and personal behavior variables were collected using a pretested interviewer-administered questionnaire. Various descriptive statistics including mean, median with interquartile range (IQR), and proportions were computed to describe study objectives. Factors of sputum smear conversion were identified by multivariable logistic regression analysis and statistical significance was determined at a p value < 0.05.ResultsOver half, 166 (59%) of bacteriologically confirmed PTB patients were males and 147 (52%) were rural dwellers. The mean age of respondents was 35 ± 5 SD years. About 88 (31.2%) of bacteriologically confirmed PTB patients had comorbidities, 102 (36.2%) faced stigma, and 54 (19%) history of cigarette smoking. The median sputum smear conversions during the intensive phase and 5th months of treatment follow up were 35 dyas (IQR: 21-56 days) and 53 days (IQR: 28-82 days), respectuvely. The majority, 85% (95% CI 76-93%) and 95% (95% CI 85-99%) of bacteriologically confirmed PTB patients underwent sputum smear conversion at the end of 2nd and 5th months of treatment, respectively. Poor knowledge on TB, being HIV positive, higher smear grading, having diabetes mellitus, undernutrition, cigarette smoking, facing societal stigma, and TB service delays were positively associated with the length of sputum smear conversion (p value < 0.05).ConclusionBased on this study, the median sputum smear conversion time was higher compared to TB program expectations and findings from former studies. The study also identified important factors associated with sputum smear conversion time. Improving health literacy of the community by revising the existing community awareness strategies is essential to enhance treatment adherence and lower infectiousness after treatment initiation.

Project description:IntroductionInstitutional delivery has been considered as one of the important strategies to improve maternal and child health and significantly reduces birth-related complications. However, it is still low in developing countries though there are some improvements. Hence, the aim of this study was to assess the prevalence of institutional delivery and associated factors in the study area.MethodsA community-based cross-sectional study was conducted. A multistage systematic sampling technique was used to select 1,394 study participants. We collected data from 18-48 years old women by using a structured questionnaire. Binary logistic regression was performed to identify factors at 95% confidence level.ResultsThe mean age of respondents was 30 (±0.15). The wealth status of 33.48% respondents was poor and 33.33% rich. The prevalence of institutional delivery was 58.17% (95% CI: 55.57%, 60.77%). Multivariable logistic regression showed that demographic factors: women age (≥35years) (AOR = 1.43; 95% CI 1.04, 1.96), having a family size of less than five (AOR = 4.61; 95% CI 3.34, 6.34), having family discussion (AOR = 4.05; 95% CI 2.74, 5.97), distance from the nearby clinic (≤30min) (AOR = 2.92; 95% CI 1.53, 5.58) and decision power about place of delivery (AOR = 2.50; 95% CI 1.56, 4.01); socio-economic factors: husband's educational status of primary school (AOR = 1.64; 95% CI 1.19, 2.24), middle level household wealth index (AOR = 1.78; 95% CI 1.25, 2.54) and rich level household wealth index (AOR = 2.01; 95% CI 1.42, 2.86); and programmatic factors: antenatal care visit during their recent pregnancy (AOR = 1.86;95% CI 1.16, 2.97) were affects institutional delivery positively. Whereas bad behavior of health workers (AOR = 0.27; 95% CI 0.19, 0.39) negatively affects institutional delivery.ConclusionInstitutional delivery was low in the study area. This study implies that strengthening family discussion and up taking antenatal care services in regular ways are a few of the suggested recommendations.

Project description:BACKGROUND:Tuberculosis (TB) is a disease of public health concern, with a varying distribution across settings depending on socio-economic status, HIV burden, availability and performance of the health system. Ethiopia is a country with a high burden of TB, with regional variations in TB case notification rates (CNRs). However, TB program reports are often compiled and reported at higher administrative units that do not show the burden at lower units, so there is limited information about the spatial distribution of the disease. We therefore aim to assess the spatial distribution and presence of the spatio-temporal clustering of the disease in different geographic settings over 10 years in the Sidama Zone in southern Ethiopia. METHODS:A retrospective space-time and spatial analysis were carried out at the kebele level (the lowest administrative unit within a district) to identify spatial and space-time clusters of smear-positive pulmonary TB (PTB). Scan statistics, Global Moran's I, and Getis and Ordi (Gi*) statistics were all used to help analyze the spatial distribution and clusters of the disease across settings. RESULTS:A total of 22,545 smear-positive PTB cases notified over 10 years were used for spatial analysis. In a purely spatial analysis, we identified the most likely cluster of smear-positive PTB in 192 kebeles in eight districts (RR= 2, p<0.001), with 12,155 observed and 8,668 expected cases. The Gi* statistic also identified the clusters in the same areas, and the spatial clusters showed stability in most areas in each year during the study period. The space-time analysis also detected the most likely cluster in 193 kebeles in the same eight districts (RR= 1.92, p<0.001), with 7,584 observed and 4,738 expected cases in 2003-2012. CONCLUSION:The study found variations in CNRs and significant spatio-temporal clusters of smear-positive PTB in the Sidama Zone. The findings can be used to guide TB control programs to devise effective TB control strategies for the geographic areas characterized by the highest CNRs. Further studies are required to understand the factors associated with clustering based on individual level locations and investigation of cases.

Project description:IntroductionFamily planning program is low-cost and an effective way to lower maternalmortality by reducing the number of high-risk births. Despite the effectiveness of the program, availability of materials, equipment and trained healthcare providers were some of the challenges in sub-Saharan African countries including Ethiopia. Determining the implementation status and identifying gaps is the aim of this evaluation.MethodA facility-based cross-sectional evaluation design with mixed method approach was employed. Quantitative data was collected through the exit interview of 477 clients from March 25-April 25, 2020. The evaluation focused on three dimensions: availability, compliance, and acceptability with multiple data sources. The quantitative data were entered in to Epi-data version 4.6 and exported to SPSS version 25 for analysis. Multivariable logistic regression was done to determine factors associated with client satisfaction. The qualitative data were transcribed, translated and analyzed by using thematic analysis. The evaluation finding was computed and compared with the preset criteria for the final judgment.ResultThe majority of the health care providers (69.8%) got family planning training in the past two years. Three health facilities (37.5%) had 24hrs electricity with backup generators whereas only 25% of the health facilities had functional piped water inside the service room. Only two (25%) health facilities had a separate room for family planning service and 37.5% of health facilities had national FP guidelines. The overall availability of required resources for family planning service at Gondar city public facilities were 62.1%. Only twenty one (26.3%) of health providers dressed based on dressing code of ethics and none of them had ID during our observation. The overall compliance level of health care providers during providing family planning services were 75.5%. About 53.9% of the clients were satisfied with family planning service provided at Gondar city public health facilities.-and-were significantly associated variables with client satisfaction.ConclusionThe overall implementation of family planning service in Gondar city public health facilities with the three evaluation dimensions were judged as fair based on pre-setting judgment matrix. It is better to improve the service through training of healthcare providers, distributed family planning guidelines to health facilities and shortening of waiting time for service.

Project description:BackgroundFarmers in developing countries, including Ethiopia, are exposed to agricultural pesticides, including pesticides that are restricted or banned in developed countries. There is little information available on pesticide use safety practices and associated factors among Ethiopian farmers, particularly in the study area.ObjectiveTo assess pesticide use safety practices and associated factors among farmers in Fogera district wetland area, Amhara region, Northwest Ethiopia.MethodsA community-based cross-sectional study design that employs quantitative and qualitative methods was used from August 25 to September 30, 2021. Four hundred thirty participants were included by using a stratified random sampling technique. Pre-tested interview questionnaires, observational checklists, and key informant and in-depth interview guides were used to collect data. The quantitative data were collected by face-to-face interviews of farmers, whereas the qualitative data were collected by in-depth interviews of selected farmers and key informant interviews of responsible stalk holders. The data were entered into Epi data version 4.6 and analyzed using SPSS version 21. Bi-variable logistic regression was used to identify factors associated with the dependent variable. A p-value of less than 0.05 was used as a cut-off point to declare a statistically significant association between factors and outcome variables. The odds ratio and 95% CI were calculated to describe the strength of the association between factors and outcome variables. The qualitative study included 35 respondents from various backgrounds and levels of expertise, which were analyzed using thematic analysis by open-code 4.03 version software.ResultThe proportion of good pesticide use safety practices in the study area was 24.4% (95% CI: 21.4%-29.3%). Educational status (adjusted odds ratio (AOR): 3.19, 95% CI: 1.44-6.71), experience of pesticide spraying (AOR: 6.85. 95% CI: 2.426-9.35), knowledge of pesticide usage (AOR: 3.40, 95% CI: 1.459-7.855), access to safety materials (AOR: 2.06, 95% CI: 1.198-3.536), and ever having received training (AOR: 4.93, 95% CI: 2.88-8.59) were factors associated with good safety practice in pesticide use. Qualitatively, limited material access, lack of government attention, insufficient training opportunities, absence of media coverage, weak enforcement of laws, and limited guideline access barred good safety practices for pesticide use.ConclusionThe study revealed that good safety practices were low in the study area. Being educated, having experience with pesticide spraying, having good knowledge of pesticide usage, having access to safety materials, and having received pesticide use training all increased the likelihood of good pesticide use practice. Insufficient training opportunities and material access, weak law enforcement, limited access to guidelines, and a shortage of media coverage were challenges identified qualitatively.

Project description:BACKGROUND:Even though there are different tuberculosis (TB) prevention and control measures implemented globally including Ethiopia, TB is still major public health problem. This is partly due to compromised quality of care delivered for tuberculosis patients in health facilities (HFs) during diagnosis, treatment and follows-up. Thus this study is intended to determine the quality of care delivered for TB patients in all public HFs of Debre Tabor town, Northwest Ethiopia. METHODS:Cross sectional study was conducted from January to May 2018. Data were collected with face-to-face interview and TB registration book review using structured questionnaire and checklist respectively. Collected data was entered and processed using SPSS and P value <0.05 was considered statistically significant. The quality of care for each HF was graded as very good, good, moderate, poor and very poor if HFs achieve [90-100%], [80-90%), [70-80%), [60-70%) and <60% of performance indicators respectively using Donabedian structure, process and outcome model of health care quality. RESULTS:All HFs have sputum collection area, enough microscopic slide, at least one functional microscope and sufficient anti TB drug supply. But HFs lack backup laboratory stains. Overall structural aspects of quality of care in all HFs were very poor achieving 42.5-52.9% structural performance indicators out of 100%. Similarly the overall process aspects of quality of care was poor in all public HFs which achieved 60-68.9% of the scores out of 100%. In the study; 68.9%, 54.5% and 80.6% of Medical Laboratory, pharmacy and other healthcare workers (HWs) provided correct response respectively on TB causative agent, risk factor, transmission, treatment, prevention, case management and case finding strategies. HWs who knew at least two TB case finding strategies in DTH was significantly higher than those HWs working in Health Centers (P = 0.004). On the other hand, except Ginbot 20 HC, HFs was graded as good by scoring 86.6-89.3% of performance indicators on the outcome aspects of quality of care. In all HFs studied, all TB patients' unit TB registration number, sex, age, TB category, treatment initiation date and intensive phase treatment start year were properly registered. Moreover 110 (78%) and 147 (69%) contact person address in DTH and HCs was properly registered on TB unit register book respectively with no statistical difference in hospital and HCs (P = 0.063). There was proper TB patients' address registration in hospital than HCs studied (P< 0.001). CONCLUSIONS:The outcome aspects of quality of care for TB patients in all HFs were promising. But structural & process aspects of quality of care was compromised which necessitate different corrective actions to be taken by different stakeholders to enhance quality of care for TB patients in public HFs studied. Moreover based on the study findings, continuous supply of drugs, laboratory equipment and reagents, availing current guideline/s in HFs, providing up-to-date training for HWs on TB and proper documentation are important to improve quality of care provided for TB patients.
