Assessment of challenges and opportunities in antibiotic stewardship program implementation in Northwest Ethiopia.

Background: Indiscriminate use of antibiotics leads to antibiotic resistance (AMR) and results in mortality, morbidity, and financial burden. Antibiotic stewardship programs (ASPs) with education can resolve a number of barriers recognized in the implementation of successful ASPs. The aim of this study was to assess health professionals' perceptions and status of ASPs in hospitals in 2022. Methods: A cross-sectional study was conducted from September 1, 2022 to October 30, 2022. A total of 181 health professionals were included, and a self-administered questionnaire was used to collect data. The status of hospitals was assessed using a checklist. The data were analyzed using SPSS version 23, and descriptive statistics and Chi-square tests (X2) at a P-value of <0.05 were used. Results: Of the 181 respondents, 163 (90.1 %), and 161 (89.0 %) believed that AMR is a significant problem in Ethiopia and globally, respectively. Easy access to antibiotics 155 (85.6 %), and inappropriate use 137 (75.7 %) were perceived as key contributors to AMR. Antibiotics were believed to be prescribed/dispensed without laboratory results 86 (47.5 %), and antibiotic susceptibility patterns were not considered to guide empiric therapy 81 (44.8 %). ASP was believed to reduce the duration of hospital stays and associated costs 137 (75.7 %), and improve the quality of patient care 133 (73.5 %), whereas 151 (83.4 %), 143 (79 %), and 142 (78.5 %) suggested education, institutional guidelines, and prospective audits with feedback interventions to combat AMR in their hospitals, respectively. There were significant differences in perception among professionals based on professional category and attempts by hospitals to implement ASPs. Although ASPs were not functioning according to standard, there have been attempts to implement it in three hospitals. The issue of ASP had never been heard in general hospitals. Currently, it is feasible to implement ASPs in four hospitals. Conclusion: The status of ASP in hospitals was very poor. Despite a lack of prior knowledge on ASPs, most respondents do have a positive perception of AMR and the implementation of ASPs. Pharmacist-led prospective audits and feedback with education and institutional guidelines for empiric antibiotic use can be better implemented in hospitals. Involvement of representatives from infection prevention and control, and collaboration among hospitals in ASP implementation will help establish a strong ASP in the area.

Relationship between Antibiotic Consumption and Resistance: A Systematic Review.

Background: Unreserved use of antibiotics exerted selective pressure on susceptible bacteria, resulting in the survival of resistant strains. Despite this, the relationship between antibiotic resistance (ABR) and antibiotic consumption (ABC) is rarely studied. This systematic review aims to review the relationship between ABC and ABR from 2016 to 2022. Methods: Articles published over 7 years (2016-2022) were searched from December 23 to 31, 2022. The search strategy was developed by using keywords for ABC and ABR. From 3367 articles, 58 eligible articles were included in the final review. Results: The pooled ABC was 948017.9 DPDs and 4108.6 DIDs where over 70% of antibiotics were from the Watch and Reserve category based on the WHO AWaRe classification. The average pooled prevalence of ABR was 38.4%. Enterococcus faecium (59.4%), A. baumannii (52.6%), and P. aeruginosa (48.6%) were the most common antibiotic-resistant bacteria. Cephalosporins (76.8%), penicillin (58.3%), and aminoglycosides (52%) were commonly involved antibiotics in ABR. The positive correlation between ABR and consumption accounted for 311 (81%). The correlation between ABR P. aeruginosa and ABC accounted for 87 (22.7%), followed by 78 (20.3%) and 77 (20.1%) for ABR E. coli and K. pneumoniae with ABCs, respectively. Consumption of carbapenems and fluoroquinolones was most commonly correlated with resistance rates of P. aeruginosa, K. pneumoniae, E. coli, and A. baumannii. Conclusion: There is a positive correlation between ABC and the rate of ABR. The review also revealed a cross-resistance between the consumption of different antibiotics and ABR. Optimizing antibiotic therapy and reducing unnecessary ABC will prevent the emergence and spread of ABR. Thus, advocating the implementation of stewardship programs plays a pivotal role in containing ABR.

A six years trend analysis of systemic antibiotic consumption in Northwest Ethiopia.

BACKGROUND: Consumption of antibiotics, a major global threat to public health, is perhaps the key driver of antibiotic resistance. Monitoring antibiotic consumption is crucial to tackling antimicrobial resistance. This study assessed antibiotic consumption trends during the last six years in the Bahir Dar branch of the Ethiopian pharmaceutical supply agency (EPSA), Northwest Ethiopia, in 2022. METHODS: Retrospective data were collected in August 2022 based on antibiotic distribution data from the Bahir Dar Brach of EPSA from July 2016 to June 2022. Data were analyzed according to the Anatomic Therapeutic Classification (ATC) developed by the World Health Organization (WHO). We measured antibiotic consumption using a defined daily dose per 1000 inhabitants per day (DIDs) based on the Agency's catchment population. Descriptive statistics and trend analyses were conducted. RESULTS: About 30.34 DIDs of antibiotics were consumed during the six years. The consumption of antibiotics decreased by 87.4%, from 6.9 DIDs in 2016/17 to 0.9 DIDs in 2021/22. Based on the WHO AWaRe classification, 23.39 DIDs (77.1%) of the consumed antibiotics were from the Access category. Consumption of Access category antibiotics was decreased by 72.7% (from 5 to 0.5 DIDs) but Watch antibiotics decreased by 54.3% (from 1.8 to 0.4 DIDs). Oral antibiotics accounted for 29.19 DIDs (96.2%) of all consumed systemic antibiotics. The average cost expenditure per DDD for all antibiotics was 54.1 birr/DDD (0.4-482.3 birr/DDD). Only seven antibiotics accounted for DU90% and the cost expenditure per DDD for the DU90% antibiotics ranged from 0.4/DDD for Doxycycline to 232.8 birr/DDD for Piperacillin/tazobactam. Overall, during the last six years, the most commonly used antibiotic was Amoxicillin (10.1 DIDs), followed by Doxycycline (5.3 DIDs) and Ciprofloxacin (3.4 DIDs). CONCLUSION: In this study, we found that antibiotic usage was low and continuously declining over time. Minimizing unnecessary antibiotic usage is one possible approach to reduced AMR. However, a shortage of access to important medicines can compromise the quality of treatment and patient outcomes. A prospective study is needed to evaluate the balance of patient outcomes and reduce AMR by optimizing the community consumption of systemic antibiotics.

The Missing Quality of Tuberculosis Care and Treatment Delivered in Public-Health Facilities, Northeast Ethiopia: A Cross-Sectional Study.

Tuberculosis (TB) remains a major global public-health problem. TB prevention and control measures are compromised by poor quality of care delivered to TB patients in health facilities during diagnosis, treatment, and follow-up; thus, this study was intended to determine the quality of TB care and treatment delivered in public-health facilities in Northeast Ethiopia. A cross-sectional study was conducted in health facilities in South Wollo zone from January to April 2018. Data were collected from each study participant through face-to-face interviews. A TB registration logbook was reviewed for every registered TB patient and compiled using a structured questionnaire and standard checklists. The quality of care for each health facility was graded as very good, good, marginal, poor, and very poor if health facilities achieved [90−100%], [80−90%), [70−80%), [60−70%), and <60% of performance indicators, respectively, using the Donabedian structure, process, and outcome model of healthcare quality. All the health facilities had at least one functional microscope, and all the facilities had sufficient TB drugs almost all the time. All the facilities had reported to have sufficient laboratory reagents and slides for sputum smear microscopy. Of 1579 patients registered, 18.5% and 66.1% were cured and successfully completed the course of treatment, respectively. The overall quality of TB care and treatment was good (72.5%), and ranged from 70.9% to 74.8% among health facilities. Outcome (83.4%) and process (80%) qualities of care were very good but the structural quality of care was very poor. In conclusion, the overall quality of TB care and treatment analysed in this study was found to be good. There should be an integrated approach to improve the quality of TB care and treatment in health facilities in Ethiopia. Based on the findings, continuous supply of anti-TB drugs, laboratory equipment and reagents, availing current guidelines, providing up to-date training for healthcare workers, and proper documentation are important to improve the quality of care delivered to TB patients.

Antibiotic-Resistant Bacteria Are Major Threats of Otitis Media in Wollo Area, Northeastern Ethiopia: A Ten-Year Retrospective Analysis.

Antibiotic resistance is an increasingly serious threat to human health that needs an urgent action. The aim of this study was to determine the prevalence and antibiotic susceptibility profiles of bacteria isolated from patient ear discharges suspected of otitis media. A retrospective analysis was performed using culture and antibiotic susceptibility test results of 1225 patients who visited Dessie Regional Health Research Laboratory from 2001 to 2011. Results showed a strong association (P < 0.001) between age and the risk of acquiring middle ear infection. The predominant bacterial isolates were Proteus spp. (28.8%), Staphylococcus aureus (23.7%), and Pseudomonas spp. (17.2%). Most of the isolated bacteria showed high resistance to ampicillin (88.5%), ceftriaxone (84.5%), amoxicillin (81.9%), and tetracycline (74.5%). About 72.5% of Proteus spp. and 62.2% of Pseudomonas spp. have developed resistance to one and more antibiotics used to treat them. This retrospective study also revealed the overall antibiotic resistance rate of bacterial isolates was increased nearly twofold (P = 0.001) over the last decade. Relatively, ciprofloxacin and gentamicin were the most effective antibiotics against all the isolates. In conclusion, antibiotic-resistant bacteria are alarmingly increasing in Wollo area, northeastern Ethiopia, and becoming a major public health problem in the management of patients with middle ear infection.

Prevalence and antibiotic resistance pattern of urinary tract bacterial infections in Dessie area, North-East Ethiopia.

BACKGROUND: Different studies have indicated that urinary tract infections frequently occur in both community and hospital environments and are of the most common bacterial infections in humans. the outcomes of urinary tract infections are increased hospitalization, increased direct patient costs and mortality. In Dessie, the prevalence of the commmon pathogens and antibiotic susceptibility pattern is not well studied sofar. Thus, the aim of this study is to address these gaps in the study area. METHODS: Retrospective study was conducted in Dessie regional health reseacrh laboratory from January 1-March 31, 2012. All culture and antibiotic susceptibility test results of patients' diagnosed with UTI from September 2002 to September 2011 G.C were included in the study. Data were abstracted using structured questionnaires and finally, entered into SPSS Windows version 16.0, and descriptive statistics was generated to meet the study objective. RESULTS: During the last ten years 680 (27.35%) bacteria were isolated in the regional laboratory. The most commonly isolated were E. coli 410 (60.29%), Pseudomonas species 59 (8.68%), Proteus species 53 (7.79%), S. aurous 50 (7.35%) and Klebsiella species 40 (5.88%). The E.coli were susceptible to Nitrofurantoin 43 (89.6%), furantoin 124 (87.3%), Nalidixic acid 91 (86.7%), kanamycin 116 (80%) & ciprofloxacin 66 (71.7%) but were almost resistant to Ampicillin, tetracycline, & trimethoprim-sulfamethoxazole. Similarly Pseudomonas and proteus species were resistant to almost all antibiotics except Gentamycin. CONCLUSION: The E.coli, pseudomonas and proteus species were the commonly isolated bacteria in the regional health research laboratory. A majority of isolated bacterial microbes were resistant to antibiotics commonly used in clinical practices and generally available in the local economy without prescription. Culture results are necessary before initiating antibiotics.

Retrospective analysis of mortalities in a tertiary care hospital in Northeast Ethiopia.

BACKGROUND: Mortalities in the health care set up are prevalent, and causes are multifactorial with variations from area to area and also from ward to ward in the same health care set up. Analysis of mortalities and its causes in Ethiopian hospitals including Dessie Referral Hospital is not adequately known. Thus, the aim of this study is to determine the prevalence of mortalities and its causes in the Dessie Referral Hospital, Northeast Ethiopia. METHODS: A retrospective analysis of mortalities during a three year period (September 2010-2012) was conducted in the Dessie Referral Hospital from August-September, 2012. All in hospital mortalities in the hospital during the last three years were included in the study. Data were collected from patient discharge recording books. Finally, data were entered into SPSS windows version 16.0 and descriptive statistics were generated to meet the study objective. RESULTS: During the last 3 years there were 1,481 (4.8%) mortalities in the hospital. Around 60.0% of the mortalities were among male patients, and two third of the mortalities were among patients aged 15 years or older. The majority of the mortalities (38.9%) were in the medical ward followed by pediatric (34.6%) and surgical (18.2%) wards. Most of the mortalities (34.8%) occurred during 2011 while least was in 2012 (31.8%). HIV/AIDS (14.8%), pneumonia (9.9%), and sepsis/shock (7.6%) were the three most common causes of mortality in the hospital during the three year period. On average, patients stayed for 2.86 (±2. 99) days in the wards before mortality. CONCLUSION: Mortalities in the wards of the Dessie Referral Hospital were high and the causes were mainly of infectious origin, HIV/AIDS and its complications being the most common causes. This calls for an integrated effort to reduce in hospital mortalities by equipping the hospital and its health care providers with the skills and medical supplies required for proper management of the most common causes of in hospital mortality reported in this study.
