ABSTRACT
Background: Adequate training in infectious diseases and antibiotic resistance is crucial for pharmacy students to participate in antibiotic stewardship programs and understand microbiology careers. Aim: The study was carried out to assess the knowledge and self-reported confidence in antibiotic resistance, antibiotic therapy, and antimicrobial stewardship (AMS) among final-year undergraduate pharmacy students in Sudan. Methods: A cross-sectional study was conducted in three universities using a 57-item online questionnaire between April and May 2022. Results: A total of 109 students (response rate 36%) participated and showed average knowledge scores of 5.6±1.7 (out of 10.0) for antibiotic resistance, 4.9±2.0 (out of 5.0) for appropriate antibiotic therapy, and 3.1±1.4 (out of 5.0) for AMS. No significant differences were observed among schools. Some students reported poor knowledge about antibiotic therapy and the consequences of resistance. One-third of students lacked confidence in interpreting microbiological results. Knowledge of antibiotic resistance among students' practice area after graduation was higher (p=0.017) and those interested in ID careers (5.8 vs 4.8) (p=0.037). Male students (5.6 vs 4.5) and those interested in ID careers (4.3 vs 3.4) (p<0.001) had higher scores of appropriate antibiotic therapy. Students attended antibiotic resistance courses (51.5 vs 45.2), and those interested in ID significantly had higher self-confidence (55.3 vs 45.8) (p=0.008). Conclusion: Pharmacy students in Sudan have substantial knowledge of AMS and antibiotic resistance with poor knowledge of antibiotic therapy. Adequate training about infectious diseases and related topics is recommended to improve pharmacy students' understanding of microbiological findings, other competencies, and skills to incorporate in antimicrobial stewardship.
ABSTRACT
Background: Intensive Care Unit (ICU) is a specialized ward where critically ill patients are admitted to provide intensive health care Inappropriate antimicrobial therapy (AMT) and high mortality rates were documented in the ICU. The influence of irrational use of empiric antibiotics on clinical outcomes in ICU patients is not well studied in Sudan. Aim: This study aims to determine the rational use of antibiotics and its impact on clinical outcomes among ICU patients. Methods: Using data collection form, a retrospective longitudinal study was conducted among ICU patients at Omdurman Military Hospital, Khartoum State. Patients admitted from January 2019 to December 2019 were included in the study. Patients who stayed in ICU < 48 hr were excluded. Appropriateness of AMT is assessed using culture sensitivity test (CST) and the American Society of Infectious Diseases (IDSA) guideline. Results: Among 102 patients, 54.9% male, one-third of patients developed nosocomial infections, 80.4% received empiric therapy with broad-spectrum antibiotics. The CST is done in 19%, and 43% patients are prescribed inappropriate AMT. Inappropriate AMT is associated with recurrent infections 38.4% (p=0.028) and high mortality 33.8% (p=0.014). Overall mortality rate 63.7% ICU patients. Elevated mortality in nosocomial 57.8%, decreased with inappropriate AMT in 21.6% patients. Significantly higher mortality rates 90.7% among uncontrolled infections (p<0.001), 80.6% nosocomial infections (p=0.001), and 76.7% renal compromised (p=0.002). Conclusion: Empirical AMT reduces the frequency of nosocomial infections, which has an impact on mortality. Inappropriate AMT is significantly associated with uncontrolled infections and lower mortality. Implementing a restrictive infectious control system and effective stewardship programs in hospital ICU wards is recommended.
