Causes and trends of adult mortality in southern Ethiopia: an eight-year follow up database study.

BACKGROUND: Broad and specific causes of adult mortalities are often neglected indicators of wellbeing in low-income countries like Ethiopia due to lack of strong vital statistics. Thus, this database study aimed to assess the causes of adult mortality using demographic surveillance data. METHODS: An 8-year (12 September 2009-11 September 2017) surveillance data from the Arba Minch Health and Demographic Surveillance Site was used for this study. Verbal autopsy methods and ICD codes were used to identify the causes of the adult deaths. The collected data were entered to the database by data clerks. We used Microsoft Excel and STATA version 16 software for data cleaning and analysis. Chi-squared test was used to see the significances of the trend analyses. RESULT: From the 943 adult deaths from 2009 to 2017 in the Health and Demographic Surveillance Site in southern Ethiopia, more than half of them were females. The specific leading cause of death in the adults were tuberculosis (16.8%), malaria (9.7%), and intestinal infectious diseases (9.6%). Communicable diseases (49.2%, 95% C.I 45.7, 52.7) accounted for about half of the deaths followed by non-communicable diseases (35%, 95% C.I 31.7, 38.4) where both categories showed an increasing trend. CONCLUSION: Although pieces of evidences are showing the shift from communicable diseases to non-communicable diseases as the major causes of adult death in developing countries, this study showed that communicable diseases are still the major causes of adult deaths. Efforts and emphasis should be given to control infectious diseases such as tuberculosis and malaria.

Magnitude and antimicrobial susceptibility profiles of Gram-Negative bacterial isolates among patients suspected of urinary tract infections in Arba Minch General Hospital, southern Ethiopia.

The emergence of drug-resistant Gram-negative bacterial uropathogens poses a grave threat worldwide, howbeit studies on their magnitude are limited in most African countries, including Ethiopia. Therefore, measuring the extent of their drug resistance is essential for developing strategies to confine the spread. A cross-sectional study was conducted at title hospital from 01 June to 31 August 2020. Midstream urine specimens were collected and inoculated onto MacConkey agar. Positive urine cultures showing significant bacteriuria as per the Kass count (>105 CFU/mL) were further subjected to biochemical tests to identify the type of uropathogens. Antimicrobial susceptibility testing was performed by the Kirby-Bauer disk diffusion technique, and potential carbapenemase producers were phenotypically determined by the modified carbapenem inactivation method as per the CLSI guidelines. Data were analyzed using SPSS version 26; P-value <0.05 was considered statistically significant. Totally, 422 patients were included, and the majority were females (54.7%). The prevalence of carbapenem-resistant Gram-negative uropathogens was 12.9%, and 64.7% of them were carbapenemase producers. Klebsiella pneumoniae (n = 5) was the predominant carbapenemase producer, followed by Pseudomonas aeruginosa (n = 4). Consumption of antibiotics prior to six months of commencement of the study, the presence of chronic diseases and hospitalizations were statistically associated with UTI caused by carbapenem-resistant Gram-negative uropathogens. Carbapenemase producers were resistant to most of the antibiotics tested. Our findings highlight the need for periodic regional bacteriological surveillance programs to guide empirical antibiotic therapy of UTI.

Bacterial profile, antimicrobial susceptibility patterns, and associated factors among bloodstream infection suspected patients attending Arba Minch General Hospital, Ethiopia.

Bacterial bloodstream infections are of great concern globally. Of late, the emergence of drug resistant bacteria worsen the related morbidity and mortality. This study was aimed to determine the bacterial profile, antimicrobial susceptibility patterns, and associated factors among the blood stream infection (BSI) suspected patients attending the Arba Minch General Hospital (AMGH), southern Ethiopia, from 01 June through 31st August, 2020. A cross-sectional study was conducted among 225 BSI suspected patients. Systematic random sampling method was used to select patients. Blood culture was done to isolate bacterial pathogens. Antimicrobial susceptibility test was performed by employing the Kirby-Bauer disc diffusion method. Descriptive statistics and multivariable logistic regression analysis were done by Statistical Package for Social Service (SPSS) version 22. The rate of prevalence of bacteriologically confirmed cases was 22/225 (9.8%). Majority of BSI were caused by Gram-positive cocci, 13/22 (59.1%), particularly the isolates of S. aureus, 7/22 (31.8%) followed by Enterococci species, 4/22 (18.2%) and coagulase-negative Staphylococci (CoNS), 2/22 (9.1%). Among the Gram-negative bacteria 9/22 (41.1%), Klebsiella species 4/22 (18.2%) was the prominent one followed by Escherichia coli 2/22 (9.1%), Pseudomonas aeruginosa 2/22 (9.1%), and Enterobacter species 1/22 (4.5%). All the isolates of Gram-negative bacteria were susceptible to meropenem whereas 69.2% of the isolates of Gram-positive counterparts were susceptible to erythromycin. Slightly above two third (68.2%) of the total isolates were multidrug resistant. Insertion of a peripheral intravenous line was significantly associated with BSI [p = 0.03; Adjusted Odds Ratio = 4.82; (Confidence Interval: 1.08-21.46)]. Overall results revealed that eventhough the prevalence of BSI in Arba Minch is comparatively lower (9.8%), multidrug resistance is alarmingly on the rise, which is to be addressed through effective surveillance and control strategies.

Antimicrobial Susceptibility Pattern and Associated Factors of Pediatric Septicemia in Southern Ethiopia.

BACKGROUND: Septicemia is one of the major causes of morbidity and mortality in pediatric patients throughout the world. Drug-resistant pathogens are one of the major challenges to control. The study aimed to identify the major etiological agents, antimicrobial susceptibility pattern and associated factors of septicemia among pediatric patients in southern Ethiopia. METHODS: A cross-sectional study was conducted on pediatric patients. Blood samples were cultured and antimicrobial susceptibility testing was conducted by Kirby-Bauer disc diffusion techniques. Data were collected by pre-tested questionnaire to identify potential associated factors of septicemia. A bivariate logistic regression analysis was used and adjusted odds ratio with 95% CI at ≤0.05 level of significance was computed to determine the presence and strength of the association. RESULTS: Of 238 participants, 27 (11.3%) of them had a positive blood culture. Staphylococcus aureus (32.2%), coagulase negative Staphylococci (25%), and Klebsiella pneumonia e (14.3%) were the predominant isolates. The isolated bacteria showed high rates of resistance to amoxicillin, ceftriaxone, streptomycin and ampicillin. Multi-drug resistance (MDR) was observed in 82.1% of the isolates. Being infant [AOR=4.18, 95% CI, (1.3-13.0)], admission >10 days [AOR=5.54, 95% CI, (1.51-20.41)], burn [AOR=3.55, 95% CI, (1.02-12.38)] and wound cases [AOR=5.52, 95% CI, (1.50-20.34)] were associated with pediatric septicemia. CONCLUSION: Gram positive bacteria were the predominant isolates and majority of isolates were MDR pathogens. Very young age, prolonged hospital stays, burn and wound cases were associated with pediatric septicemia. Establishing antibiotic stewardship is mandatory to minimize the high prevalence of drug resistance.

Trend of declining bed net utilization among pregnant women in Ethiopia: new data from the Arba Minch Health and Demographic Surveillance System, 2010-2016.

BACKGROUND: Bed net utilization is one of the important methods of malaria prevention. Malaria during pregnancy is one of the fatal diseases which mostly leads to the death of the mother and the fetus. Some of the complications of malaria during pregnancy are: intrauterine growth restrictions, intrauterine fetal death, and stillbirth. The main challenge of malaria treatment is that most of the anti-malarial drugs are not safe to use during pregnancy. The use of bed net is the most effective method of prevention of malaria during pregnancy. There is a paucity of information on bed net utilization among pregnant women in the study setting. Hence, this study aims to assess the trends of bed net utilization among pregnant women in Arba Minch Health and Demography Surveillance Site (HDSS), Southern Ethiopia. METHODS: The study was conducted in the Arba Minch HDSS. The observation started in 2010 till 2016, using a repeated cross-sectional study design. The data was collected using interviewer administered questionnaire biannually with a total of 14 rounds of data collection from 2010 to 2016. A total of 2657 pregnant women were included in the study. Descriptive statistics such as frequency and proportion were used to present the findings of each variable. RESULTS: Out of 2657 mothers included in the study, more than half, 1521 (63.6%), of the study participants were in the age group between 20 and 29 years. About one-third of the study population 793 (29.8) were having no schooling. The trend of bed net utilization decreased from 83.6% in 2010 to 36.5% in 2016. CONCLUSION: The trends of bed net utilization decreased from 2010 to 2016 in Arba Minch HDSS. Utilization of bed net by pregnant women in the area need to be increased as it is malaria endemic. The government should strengthen the existing bed net distribution strategy. Further research is needed to investigate the cause of decreasing bed net utilization.

Antimicrobial susceptibility pattern, and associated factors of Salmonella and Shigella infections among under five children in Arba Minch, South Ethiopia.

BACKGROUND: Diarrheal diseases continue to be the major cause of morbidity and mortality among children under 5 years. Salmonella and Shigella specious are the major enteric pathogen causing diarrhea among children worldwide. Examination of stool sample is the most sensitive method to diagnose diarrheal disease in children. This study aimed to determining the prevalence, antimicrobial susceptibility pattern and associated factor of Salmonella and Shigella infection among under five children. METHODS: A cross sectional study was conducted on under 5 years children attending Arba Minch town. Pre-tested and structured questionnaire was used for collecting data about socio-demographic characteristics and associated factors. Stool sample was used to isolate and identified the pathogen. Antimicrobial susceptibility test was performed for isolated Salmonella and Shigella specious. A logistic regression analysis was used to see the association between different variables and outcome variable. Odds ratio with 95% CI was computed to determine the presence and strength of the association. RESULTS: A total of 167 under five children were included in the study. About 57% of participants were males with the mean age of 32 months. The overall prevalence of Salmonella and Shigella species infection was 17.45% with 12.6% Salmonella species. The isolates were resistant to common antibiotics such as Amoxicillin, Erythromycin, Chloramphenicol, Clindamycin, Norfloxacin, Ciprofloxacin, Cotrimoxazole, and Gentamycin. Urban resident [AOR = 7.11; 95% CI (2.3, 22.2)], month income < 1000 Ethiopian birr [AOR = 6.5; 95% CI (2.0, 21.4)], absence of waste disposal system [AOR = 3.3; 95% CI (1.2, 9.3)], poor hand washing habit [AOR = 6.0; 95% CI (2.0, 18.2)], untrimmed finger nail [AOR = 3.7; 95% CI (1.4, 10.6)], and use of napkin [AOR = 3.2; 95% CI (1.1, 9.3)] had significant association with Salmonella and Shigella infection. CONCLUSION: Salmonella and Shigella species infections were higher as compared the national prevalence. This study also revealed that the enteric infection were significantly associated with finger nail status, residence, hand washing practice, month income of parents, usage of napkin after toilet, and absence of waste disposal system. Therefore, working on identified associated factors and regular drug susceptibility test is mandatory to reduce the problem.

The practice of venous blood collection among laboratory and non-laboratory professionals working in Ethiopian Government Hospitals: a comparative study.

BACKGROUND: Pre-analytical phase of overall laboratory testing system continues to be the major source of errors that affect patient safety and health care system. One of the activities in this phase is venous blood collection (VBC), the most common type of specimen drawn or sent to clinical laboratories for further analysis; and the source for a potentially numerous types of errors. In this study, we focused on determining and comparing desirability/undesirability of activities during VBC in Ethiopian hospitals among different groups of professionals. METHODS: We conducted a cross-sectional comparative study in three government hospitals in South Ethiopia from February 2012 to September 2012. Randomly selected professionals who participate in VBC in outpatient and inpatient departments were requested to fill in structured and pretested questionnaire regarding their practice of VBC and their replies were categorized as 'desirable' and 'undesirable' according to Clinical and Laboratory Standards Institute (CLSI) standard. Then, data was analyzed using Medcalc® version 12.1.4 software. P value of less than 0.05 was considered as statistically significant. RESULTS: In our study, 120 professionals were included among which 15.8% (n = 19) were laboratory professionals while the remaining 84.2% (n = 101) were non-laboratory professionals. Conscious patient identification in pre-collection phase of VBC and position of patients' hands in actual collection phase of VBC involved the highest proportion of undesirability among both groups of professionals. However, in the post collection phase, specimen transferring from syringes to test tubes (15.8%) and mixing specimen with additives (63.4%) involved highest proportions of undesirability among laboratory and non-laboratory professionals respectively. Laboratory professionals reported better desirable practice in patient identification frequency, labeling and checking expiry dates of test tubes, specimen transfer and transport practices. CONCLUSION: In conclusion, preparatory activities of VBC involved the highest proportions of undesirable practices among both groups of professionals. However, relatively better proportions of desirability were seen among laboratory professionals than non-laboratory professionals in some pre- and post-collection phase activities. The difference might be seen as a result of better qualification, education and training experience on VBC among laboratory professionals.

Prevalence of intestinal parasitic infections among highland and lowland dwellers in Gamo area, South Ethiopia.

BACKGROUND: Epidemiological information on the prevalence of intestinal parasitic infections in different regions is a prerequisite to develop appropriate control strategies. Therefore, this present study was conducted to assess the magnitude and pattern of intestinal parasitism in highland and lowland dwellers in Gamo area, South Ethiopia. METHODS: Community-based cross-sectional study was conducted between September 2010 and July 2011 at Lante, Kolla Shelle, Dorze and Geressie kebeles of Gamo Gofa Zone, South Ethiopia. The study sites and study participants were selected using multistage sampling method. Data were gathered through house-to-house survey. A total of 858 stool specimens were collected and processed using direct wet mount and formol-ether concentration techniques for the presence of parasite. RESULTS: Out of the total examined subjects, 342(39.9%) were found positive for at least one intestinal parasite. The prevalence of Entamoeba histolytica/dispar was the highest 98(11.4%), followed by Giardia lamblia 91(10.6%), Ascaris lumbricoides 67(7.8%), Strongyloides stercoralis 51(5.9%), hookworm 42(4.9%), Trichuris trichiura 24(2.8%), Taenia species 18(2.1%), Hymenolepis nana 7(0.6%) and Schistosoma mansoni 1(0.12%). No statistically significant difference was observed in the prevalence of intestinal parasitic infections among lowland (37.9%) and highland dwellers (42.3%) (P = 0.185). The prevalence of intestinal parasitic infection was not significantly different among the study sites but it was relatively higher in Geressie (42.8%) than other kebeles. Sex was not associated with parasitic infections (P = 0.481). No statistically significant difference of infection was observed among the age groups (P = 0.228) but it was higher in reproductive age group. CONCLUSIONS: The high prevalence of intestinal parasitic infections among the lowland and highland dwellers in Gamo area indicated that parasitic infections are important public health problems. Thus, infection control measures and the development of awareness strategies to improve sanitation and health education should be considered.
