Inappropriate Antibiotic Use Among Inpatients Attending Madda Walabu University Goba Referral Hospital, Southeast Ethiopia: Implication for Future Use

Evaluating empiric antibiotic prescribing for hospitalized children in Mozambique through the introduction of a quarterly syndromic antibiogram: An implementation science protocol

Antimicrobials are the most frequently prescribed drug in pediatrics, with an estimated 37% of infants and 61% of hospitalized children having received them. Approximately 20-50% of prescriptions have been shown to be potentially unnecessary or inappropriate. The World Health Organization (WHO) estimates that the continued increase in antimicrobial resistance by the year 2050 will lead to the death of 10 million people per year. This paper describes a protocol to be used in a future study to evaluate the implementation of a quarterly syndromic antibiogram, aimed to improve the use of antibiotics for the treatment of pediatric bacterial infections at the Maputo Central Hospital, Mozambique. This study uses implementation science methods framed by the Dynamic Adaption Process (DAP) and RE-AIM conceptual frameworks to develop a multi-phase, mixed-methods evaluation utilizing qualitative and quantitative approaches. The pediatric inpatient services at HCM consist of approximately 18 physicians and 60 nurses. Additionally, the microbiology laboratory consists of eight laboratory technicians. We anticipate analyzing approximately 9,000 medical records. Qualitative methods include in-depth interviews with clinicians, laboratory technicians, and administrators to explore current knowledge and practices around antibiotic decision making, facilitators and barriers to intervention implementation, as well as acceptability and satisfaction with the intervention roll-out. Qualitative analysis will be performed with NVivo 12 software. Quantitative methods include extracting data from existing records from the pediatric ward of Hospital Central de Maputo (HCM) guided by the RE-AIM framework to explore intervention utilization and other factors influencing its implementation. Quantitative descriptive and inferential statistical analysis will be performed using R Studio statistical software. The findings from this evaluation will be shared with hospital administrators and relevant national policymakers and may be used by the Ministry of Health in deciding to expand this approach to other hospitals. The expected results of this research include the development of standard operating guidelines for the creation, distribution, and use of a quarterly syndromic antibiogram for antibiotic decision making that is informed by local epidemiology. Findings from this study will be used to develop a larger multi-site trial in Mozambique.

Genotypic and phenotypic drug resistance patterns of Mycobacterium tuberculosis isolated from presumptive pulmonary tuberculosis patients in Ethiopia: A multicenter study

BACKGROUND

The emergence of drug-resistant tuberculosis (DR-TB) has been a major obstacle to global tuberculosis control programs, especially in developing countries, including Ethiopia. This study investigated drug resistance patterns and associated mutations of Mycobacterium tuberculosis Complex (MTBC) isolates from the Amhara, Gambella, and Benishangul-Gumuz regions of Ethiopia.

METHODS

A cross-sectional study was conducted using 128 MTBC isolates obtained from patients with presumptive tuberculosis (TB). Phenotypic (BACTEC MGIT 960) and genotypic (MTBDRplus and MTBDRsl assays) methods were used for drug susceptibility testing. Data were entered into Epi-info and analyzed using SPSS version 25. Frequencies and proportions were determined to describe drug resistance levels and associated mutations.

RESULTS

Of the 127 isolates recovered, 100 (78.7%) were susceptible to four first-line anti-TB drugs. Any drug resistance, polydrug resistance, and multi-drug resistance (MDR) were detected in 21.3% (27), 15.7% (20), and 15% (19) of the isolates, respectively, by phenotypic and/or genotypic methods. Mono-resistance was observed for Isoniazid (INH) (2, 1.6%) and Streptomycin (STR) (2, 1.6%). There were two genotypically discordant RIF-resistant cases and one INH-resistant case. One case of pre-extensively drug-resistant TB (pre-XDR-TB) and one case of extensively drug-resistant TB (XDR-TB) were identified. The most frequent gene mutations associated with INH and rifampicin (RIF) resistance were observed in the katG MUT1 (S315T1) (20, 76.9%) and rpoB (S531L) (10, 52.6%) genes, respectively. Two MDR-TB isolates were resistant to second-line drugs; one had a mutation in the gyrA MUT1 gene, and the other had missing gyrA WT1, gyrA WT3, and rrs WT1 genes without any mutation.

CONCLUSIONS

The detection of a significant proportion of DR-TB cases in this study suggests that DR-TB is a major public health problem in Ethiopia. Thus, we recommend the early detection and treatment of DR-TB and universal full first-line drug-susceptibility testing in routine system.

Antimicrobial use-related drug therapy problems and associated factors among patients in the medical ward of Wachemo University Nigist Eleni Mohammed Memorial Comprehensive Specialized Hospital, Southwest Ethiopia

Objective

This study assessed the antimicrobial use-related drug therapy problems (DTPs) among patients admitted to the medical ward of Wachemo University Nigist Eleni Mohammed Memorial Comprehensive Specialized Hospital (WCUNEMMCSH), Southwest Ethiopia.

Methods

A hospital-based prospective observational study design was used to assess antimicrobial use-related DTPs among patients admitted to the medical ward of WCUNEMMCSH from June to August 2021. Data were collected using a structured data abstraction format.

Results

In all, 128 patients admitted to the medical ward were enrolled. Among the study participants, at least one form of antimicrobial DTP occurred in 98 (76.6%) of them. The most prevalent DTPs were unnecessary drug treatment in 42 (32.8%), the need for additional drug treatment in 36 (28.1%), and non-adherence in 30 (23.4%) of the patients. There were a total of 288 antimicrobial drug orders. Ceftriaxone 120 (41.7%) and azithromycin 69 (24.0%) were the most commonly prescribed antimicrobial drugs. In multivariate logistic analysis, the length of hospital stay (adjusted odds ratio (AOR) = 2.97, 95% confidence interval (CI): 1.06-8.32; p = 0.04) and the number of diagnosed diseases (AOR = 3.10, 95% CI: 1.12-8.15, p = 0.02) were predictors of antimicrobial use-related DTPs.

Conclusion

Antimicrobial use-related DTPs are common among patients admitted to the medical ward of WCUNEMMCSH. Health professionals should work together to reduce the high prevalence of DTPs among medical ward admitted patients in this hospital.

Inappropriate use of antibiotics and its predictors in pediatric patients admitted at the Central Hospital of Nampula, Mozambique

Background

Antibiotics are synthetic or natural substances used to treat bacterial infectious diseases. When used incorrectly, they can be a factor in the development of antimicrobial resistance, increased treatment time, costs, and mortality. The present study aimed to assess the pattern of inappropriate use of antibiotics and their predictors in pediatric patients admitted to the Central Hospital in Nampula, Mozambique.

Methods

A cross-sectional, retrospective study with a quantitative approach was conducted between January and July 2019. The population consisted of children ages 0–10 years hospitalized in the pediatric ward I. Binary logistic regression was used to determine risk factors for the inappropriate use of antibiotics with 95% confidence interval.

Results

The prevalence of antibiotic use among pediatric patients was 97.5%. Of the 464 antibiotics prescribed, 39.9% were for patients suffering from gastroenteritis, 21.8% and 9.1% for those affected with pneumonia and malaria, respectively. Most antibiotics were for parenteral use (95.9%, 445/464). Many (36.5%) of the prescriptions had errors, primarily in the duration of treatment (74.0%) or dosage (24.4%). Binary logistic regression analysis revealed that patients prescribed ≥ 3 antibiotics (OR = 2.83, 95% CI 1.245–6.462, p-value = 0.013) or hospitalized for a short time (OR = 1.88, 95% CI 1.133–2.3140, p-value = 0.015) were more likely to experience inappropriate use of antibiotics.

Conclusion

The study showed both a high prevalence of antibiotic use and a high error rate in prescriptions, especially among patients prescribed ≥ 3 antibiotics or hospitalized for a short time. These results are concerning, since inappropriate and excessive use of antibiotics is a major factor in the development of antibiotic-resistant microorganisms. Therefore, policies to reduce the inappropriate and excessive use of antibiotics are necessary.

Antibiotic use among hospitalized children with lower respiratory tract infections: a multicenter, retrospective study from Punjab, Pakistan

BACKGROUND

Lower respiratory tract infection (LRTI) is one of the triggering factors toward death in children below the age of five years necessitating appropriate antibiotic selection. This study aimed to evaluate antibiotic use among hospitalized children (≤5 years age) with LRTIs.

METHODS

A retrospective study was conducted in seven health facilities of the central region of Punjab province of Pakistan. The medical records of hospitalized children ≤5 years diagnosed with LRTI were thoroughly evaluated to get information on demographics, clinical characteristics, and details of prescribed antibiotics. The appropriateness of antibiotics was assessed according to guidelines of the British National Formulary due to a lack of indigenous standard treatment guidelines.

RESULTS

The medical records of 5926 children were searched with the majority (70.9%) diagnosed with community-acquired pneumonia (CAP) followed by acute bronchitis (14.1%). Ceftriaxone plus ampicillin and ceftriaxone plus ampicillin plus amikacin were prescribed to 39% and 11.7% study population, respectively. One-fourth of children were prescribed the wrong dose, and more than half were encountered with the incorrect route of antibiotic administration. Alarmingly, 90.2% of antibiotic prescriptions were inappropriate in our findings.

CONCLUSIONS

Current surveillance study revealed a worrying degree of antibiotic misuse among hospitalized LRTI children aged ≤5 years.

Antimicrobial Drug Therapy Problems Among Patients in the Outpatient Department of Ataye Hospital, Northeast Ethiopia

Background

Antimicrobial drug therapy problems refer to incorrect and inappropriate utilization of antimicrobials which affect patient’s health outcomes and results in bacterial resistance. Incorrect use of antimicrobial agents is a key driver for the spread of antimicrobial drug resistance. Improving drug therapy problems has an important effect on the patients’ health, treatment costs, and enhancing patients’ quality of life. Hence, the aim of the present study was to assess antimicrobial drug therapy problems among patients in the Outpatient Department of Ataye hospital, Northeast Ethiopia.

Methods

A hospital-based retrospective cross-sectional study design was used to assess antimicrobial drug therapy problems among patients in Ataye hospital from September 2018 to February 2019. Data were collected by trained graduating pharmacy students by reviewing medical records of patients using checklists and questionnaires.

Results

A total of 248 patient cards were included in this study. At least one antimicrobial drug therapy problem had occurred among 96 (38.7%) of the study participants. The most common drug therapy problem was the need for additional drug therapy which was incurred by 38 (15.3%) of the study participants and ineffective antimicrobial therapy was experienced by 22 (8.9%) of the patients. Tetracyclines 25 (26%), fluoroquinolones 19 (19.8%), and penicillins 18 (18.8%) were the most common classes of antimicrobials prone to drug therapy problems.

Conclusion

The current study revealed that nearly two-fifths of the study participants had experienced at least one form of antimicrobial drug therapy problem. The most common drug therapy problem was the need for additional drug therapy and the use of ineffective antimicrobial therapy. Tetracyclines, fluoroquinolones, and penicillins were the main classes of antimicrobials involved in the drug therapy problem.
