Antimicrobial resistance profiles and associated factors of Acinetobacter and Pseudomonas aeruginosa nosocomial infection among patients admitted at Dessie comprehensive specialized Hospital, North-East Ethiopia. A cross-sectional study

ABSTRACT:

Introduction

Hospital admitted patients are at increased risk of nosocomial infections (NIs) with multi-drug resistant (MDR) pathogens which are prevalent in the hospital environment. Pseudomonas aeruginosa (P. aeruginosa) and Acinetobacter baumannii (A. baumannii) are common causes of NIs worldwide. The objective of this study is to determine antimicrobial resistance profiles and associated factors of Acinetobacter spp and P. aeruginosa NIs among hospitalized patients.

Methods

A cross-sectional study was conducted at Dessie comprehensive specialized hospital, North-East Ethiopia, from February 1 to April 30, 2020. A total of 254 patients who were suspected of the bloodstream, urinary tract, or surgical site nosocomial infections were enrolled consecutively. Socio-demographic and other variables of interest were collected using a structured questionnaire. Specimens were collected and processed following standard microbiological procedures. Antimicrobial susceptibility was determined using the Kirby-Bauer disk diffusion method following Clinical and Laboratory Standards Institute guidelines. Data were analyzed with SPSS version 23 and p-value < 0.05 was considered statistically significant.

Results

Overall, 13% of patients had nosocomial Acinetobacter spp and/or P. aeruginosa infections. The culture positivity rate was 16(6.3%) for Acinetobacter spp and 18(7.1%) for P. aeruginosa. Patients admitted in the surgical ward (Adjusted odds ratio (AOR):10.66;95% confidence interval (CI):1.22–93.23), pediatric ward (AOR:14.37;95%CI:1.4–148.5), intensive care unit (AOR:41.93;95%CI:4.7–374.7) and orthopedics (AOR:52.21;95%CI:7.5–365) were significantly at risk to develop NIs compared to patients admitted in the medical ward. Patients who took more than two antimicrobial types at admission were 94% (AOR:0.06; 95% CI:0.004–0.84) times more protected from NIs compared to those who did not take any antimicrobial. About 81% of Acinetobacter spp and 83% of P. aeruginosa isolates were MDR. Amikacin and meropenem showed promising activity against Acinetobacter spp and P. aeruginosa isolates.

Conclusion

The high prevalence of MDR Acinetobacter spp and P. aeruginosa nosocomial isolates enforce treating of patients with NIs based on antimicrobial susceptibility testing results.

Project description:IntroductionPatient safety culture is defined as the attitudes, perceptions, and values that staffs share within an organization related to patient safety. The safety of health care is now a major global concern. It is likely that millions of people suffer disabling injuries or death directly related to medical care. Particularly in developing and transitional countries, patient harm is a global public health problem. The objective of the study is to assess patient safety culture and associated factors among health care professionals working in public hospitals in Dessie town, North East Ethiopia, 2019.MethodsFacility based quantitative study was employed from March 15 -April 30, 2019 in public hospitals in Dessie town. Four hundred and twenty two health care professionals were recruited to complete a structured pretested self-administered questionnaire. The data was cleaned, coded and entered in to Epi Info-7 and exported to SPSS version 20. Data was further analyzed using bivariate and multivariate logistic regression analyses. Variables with P value of less than 0.05 in multivariate analysis were declared as statistically significant at 95% CI.ResultsOf the 422 recruited a total of 411 participants completed the survey with a response rate of 97.4%. Close to half (184(44.8%)) of the participants indicated good patient safety culture. Good patient safety culture was positively associated with working in primary hospital (AOR = 2.56, 95% CI = 1.56, 4.21). On the other hand, good patient safety culture was negatively associated with health professional's age between 25-34 year (AOR = 0.25, 95% CI = 0.08-0.74) and working in Pediatrics ward (AOR = 0.39, 95% CI = 0.17-0.9) and in emergency ward (AOR = O.25, 95%CI = 0.09-0.67).ConclusionThe overall level of patient safety culture was under 50%. Good patient safety culture had positive association with working in primary hospital and negative association with professionals' age between 25-29 year, 30-34 year and working in pediatrics and emergency ward. Implementing actions that support all dimensions of safety culture should be promoted at all levels of hospitals.

Project description:BACKGROUND:Multi-drug resistant (MDR) Acinetobacter baumannii and Pseudomonas aeruginosa are major causes of nosocomial infections globally. They are the current World Health Organization critical priority pathogens for resistance, Antimicrobial resistance (AMR) surveillance and discovery of new antibiotics. However, there is paucity of data on nosocomial infections (NIs) caused by such superbugs in Ethiopia. Therefore, this study determined the magnitude and profile of nosocomial MDR A. baumannii and P. aeruginosa infections among patients hospitalized at Felegehiwot referral hospital, Northwest Ethiopia. METHODS:A cross-sectional study was conducted at Felegehiwot referral hospital from April 1 to July 31, 2018. A total of 238 patients with blood stream, urinary tract and surgical site NIs were enrolled conveniently. Either blood, urine and wound swab specimens were collected and processed using standard bacteriological procedures. A. baumannii and P. aeruginosa isolates were identified using standard bacteriological techniques and confirmed by automated Vitek2 Compact. Antimicrobial susceptibility testing on isolates was performed using the disk diffusion technique. The results were interpreted as per the standard zone sizes of Clinical and Laboratory Standards Institute.Chi-square test was done to determine associations among variables. P value <?0.05 was considered statistical significant. RESULTS:The median age of participants was 29?years. Overall,20(8.4%) of patients had nosocomial MDR A. baumannii and P. aeruginosa infections. The proportion of nosocomial MDR blood stream, urinary tract and surgical site infections were 13(8.9%), 5(8.3%) and 2 (6.3%), respectively. Patients with NI had lower mean age (24.9?years) (P?=?0.035). All isolates of NIs were from patients with intravenous catheterization. The frequency of NI was 9(3.8%) for MDR A. baumannii and 11(4.6%) for MDR P.aeruginosa. A. baumannii and P. aeruginosa isolates were 100% MDR. All isolates of A. baumannii and P. aeruginosa were 100% resistant to ampicillin and piperacillin.A. baumannii isolates were 33.3 and 44.5% resistance against meropenem and ciprofloxacin, respectively while P.aeruginosa isolates revealed 36.4 and 45.5% resistance against ciprofloxacin and meropenem, respectively. CONCLUSIONS:Health care associated infections of MDR A.baumannii and P. aeruginosa are critical problems in the study area. Therefore, urgent focused interventions required to contain the spreading of MDR NIs. Treatment of NIs for patients on health care should be guided by antimicrobial susceptibility testing.

Project description:OBJECTIVE:In Ethiopia, community-level knowledge about the current COVID-19 pandemic has not been well studied. This study is aimed to assess knowledge level and factors influencing the prevention of the COVID-19 pandemic among residents of Dessie and Kombolcha city administrations, Ethiopia. DESIGN:Community-based cross-sectional study. SETTINGS:Dessie and Kombolcha city administrations. PARTICIPANTS:Participants were household heads or members (n=828, >18?years) who have lived in the study area for at least 2?months preceding the survey. METHODS:Binary logistic regression was used for a single outcome and multiple response variables. In the multivariable regression model, a value of p<0.05?and adjusted OR (AOR) with 95% CI were used to identify factors associated with knowledge level of the community. Epi Info V.7.2 and SPSS V.20 software were used for data entry and analysis, respectively. OUTCOME:Knowledge level. RESULTS:A total of 828 participants was involved with a response rate of 98%. Women were 61.7%. Participants' mean (±SD) age was 39 (±14) years. Of the total participants 54.11% (95% CI 50.6% to 57.6%) had inadequate knowledge about COVID-19 prevention. Significant associations were reported among women (AOR=1.41; 95%?CI 1.03 to 1.92); age ?65 years (AOR=2.72; 95%?CI 1.45 to 5.11); rural residence (AOR=2.69; 95%?CI 1.78 to 4.07); unable to read and write (AOR=1.60; 95%?CI 1.02 to 2.51); information not heard from healthcare workers, mass media and social media (AOR=1.95; 95%?CI 1.35 to 2.82), (AOR=2.5; 95%?CI 1.58 to 4.19) and (AOR=2.13; 95%?CI 1.33 to 3.42), respectively, with inadequate knowledge. CONCLUSION:These findings revealed that more than 50% of participants had inadequate knowledge about COVID-19. It highlights the need for widespread awareness campaigns about COVID-19 through mass media, healthcare professionals and social media as sources of information. House-to-house awareness creation is recommended to address older adults who are more vulnerable to the pandemic.

Project description:BackgroundEthiopia is one of the developing countries with the poorest health status and the health services utilization is generally low with different patterns in different regions of the country. Therefore, the aim of this study was to assess utilization of modern health services and associated factors in Dessie, Ethiopia.MethodsA cross sectional study design was employed from January to March, 2015 in Dessie City. The total sample was 420 adults. Adults were selected by stratified random sampling. The strata were made using residence as urban and rural residents. The data was collected using pre-tested, interviewer administered questionnaire. The data was entered into Epi infoTM7 software and exported to Statistical Package for Social Sciences (SPSS) version 20 Software for analysis. Binary logistic regression was used to evaluate independent effect of each variable on modern health service utilization by controlling the effect of others. The strength of association between dependent variable and independent variables was expressed by odds ratio with 95% confidence interval.ResultsThe overall modern health services utilization rate was 41.8%. Being Female sex, annual income greater than poverty line, poor perception of health status, high perceived severity of illness, two or more than two number of illnesses in the last 12 months prior to the survey and presence of chronic health problem were found to have a significant association with utilization of modern health services.ConclusionModern health services utilization was found to be low. Being female sex, annual income above poverty line, having poor perceived health status, having two or more than two illnesses, severe perceived severity of illness and having chronic health problem were found to have a statistically significant association with utilization. Therefore, efforts have to be made to increase utilization of modern health services through establishing systems like health extension workers and health development army.

Project description:Introduction Metabolic syndrome is a group of metabolic risk factors which are associated with an increased risk of cardiovascular disease and type2 diabetes. Nowadays, several studies have shown that the burden of metabolic syndrome is increasing among epileptic patients, and leads to MS-associated complications, including cardiovascular disease. However, getting published documents has been limited in Ethiopia and the study area. Therefore, we aimed to analyze the magnitude and associated factors of metabolic syndrome among epileptic patients in Dessie Comprehensive Specialized Hospital in compression with respective controls. Methods Hospital-based comparative cross-sectional study design was implemented from June 25 to August 20, 2021. A total of 204 participants with an equal number of cases and controls (n = 102 each) were included. The data was collected through face-to-face interviews and biochemical analyses such as fasting blood glucose and lipid profiles were done through the enzymatic technique. The magnitude of metabolic syndrome was determined using both National Cholesterol Education Program Adult Treatment Panel III and International Diabetes Federation definition criteria. The STATA version 14 was used for statistical data analysis, and a comparison of categorical and continuous variables was done with χ2 and an independent t-test, respectively. The multivariable binary logistic regression analysis was used to identify factors associated with metabolic syndrome, and variables having a P-value of <0.05 were considered statistically significant. Result The prevalence of metabolic syndrome among the epileptic group was (25.5% in National Cholesterol Education Program Adult Treatment Panel III and 23.5% in International Diabetes Federation criteria), whereas it was 13.7% in National Cholesterol Education Program Adult Treatment Panel III and 14.7% in International Diabetes Federation criteria among control groups. According to the International Diabetes Federation criteria, low physical activity (adjusted odds ratio = 4.73, 95% CI: 1.08–20.68), taking multiple antiepileptic drugs (adjusted odds ratio = 8.08, 95% CI: 1.52–42.74), having a total cholesterol level of ≥ 200 mg/dl (adjusted odds ratio = 5.81, 95%: 1.32–41.13) and body mass index (adjusted odds ratio = 1.57, 95% CI = 1.16–2.11) were significantly associated with metabolic syndrome among epileptic participants. Applying National Cholesterol Education Program Adult Treatment Panel III criteria, taking multiple antiepileptic drugs (adjusted odds ratio = 6.81, 95% CI: 1.29–35.92), having a total cholesterol level > 200 mg/dl (adjusted odds ratio = 7.37, 95% CI: 1.32–41.13) and body mass index (adjusted odds ratio = 1.53, 96% CI: 1.16–2.01) were also significantly associated. Conclusion The prevalence of metabolic syndrome among epileptic patients was higher than that of control groups and reaches statistically significant by National Cholesterol Education Program Adult Treatment Panel III. Being on multiple antiepileptic drugs, body mass index, having low physical activity and raised total cholesterol were significantly associated with metabolic syndrome among the epileptic group. Therefore, it is better to focus on controlling weight, having sufficient physical exercise, and regular monitoring of total cholesterol levels in epileptic patients.
