Introduction: Many COVID-19 vaccines have been emerging with different efficacy and safety profiles. So far, very little attention has been paid to severity and reactogenicity of COVID-19 vaccine among healthcare workers. Thus, the aim of this study is to investigate the side effects associated with the first dose of AstraZeneca COVID-19 vaccine among healthcare workers (HCWs) and nonhealthcare workers (non-HCWs). Method: This is an observational cross-sectional study conducted at King Abdullah bin AbdulAziz University Hospital, Saudi Arabia, between February 28 and March 12, 2021. The major outcomes were the reported side effects of day 1, day 2, and day 3 after vaccination among HCWs and non-HCWs. Other outcomes included the onset and the duration of the reactions or the side effects that were reported. Results: A total of 526 participants completed the survey with 173 (32.8%) HCWs and the remaining majority were non-HCWs. Some of the most frequently reported side effects among the participants on the first day were muscle aches (49%), followed by fever (42%) and headache (40%). HCWs experienced more muscle aches, headache, sore throat, and abdominal pain, which were statically significant, compared to non-HCWs. The mean onset of symptoms was 16 (±15.3) h in the HCW arm compared with 12.2 (±10.2) h in non-HCWs (p = 0.0024). Furthermore, the mean duration of symptoms in the HCW group was 37 (±19) h compared with 32.3 (±13) h in the non-HCW group (p = 0.067). Conclusion: The reported side effects were common but not pressing in both groups. HCW respondents appeared to have more COVID-19 vaccine-associated symptoms.

Background: Urinary tract infections (UTIs) are one of the most common health problems worldwide and mainly affect women. This study aimed to evaluate the prevalence of UTIs in pregnant women and determine the antimicrobial resistance patterns of bacterial pathogens isolated from pregnant and nonpregnant women in Riyadh, Saudi Arabia. Methods: This retrospective cohort study was conducted at an academic medical center in Riyadh, Saudi Arabia, from January to June 2022. The study included all urine cultures performed for adult women during the study period. We excluded urine culture performed for women on antibiotics prescribed for any infection, children, and men. Using the SPSS (version 27) package, descriptive statistics and chi-square tests were used to analyze the data, and p < 0.05 was considered to indicate statistical significance. Results: A total of 2,418 urine cultures performed during the study period were included (985 and 1,433 for pregnant and nonpregnant women, respectively). The overall prevalence of UTIs in pregnant women was 5% (95% CI 3.6–6.4); 10 (1%) women were symptomatic, and 40 (4%) women were asymptomatic. Of the entire cohort, 244 (10.1%) women were diagnosed with UTIs based on bacterial cultures. The predominant bacteria in both pregnant and nonpregnant women were Escherichia coli (134, 54.9%), followed by Klebsiella pneumoniae (48, 19.6%). The antibiotic susceptibility criteria for Escherichia coli and Klebsiella pneumoniae were as follows: nitrofurantoin (94% and 18.8%, respectively), amoxicillin-clavulanic acid (82.8% and 70.8%, respectively), ciprofloxacin (65.7% and 83.3%, respectively), trimethoprim-sulfamethoxazole (65.7% and 79.2%, respectively) and cephalothin (47% and 68.8%, respectively). Conclusion: Compared to the findings of other similar studies, the prevalence of UTIs was lower in pregnant women. This may be because the patient population was composed of healthy and educated women who received prenatal education and underwent prenatal assessment as per institutional guidelines. Nitrofurantoin and amoxicillin-clavulanic acid are recommended for use as an empirical therapy for UTIs in pregnant and nonpregnant women because bacteria have the least amount of resistance to these drugs.

Background: The Infectious Diseases Society of America (IDSA) recommends against screening for and/or treating asymptomatic bacteriuria (ASB). This study aims to evaluate the inappropriate use of antibiotics in ASB before and after Antimicrobial Stewardship Program (ASP) implementation and advance towards its appropriate use. Method: We performed a retrospective study of patients diagnosed with ASB from 2016 to 2019 at a tertiary hospital in Saudi Arabia. This study included hospitalized patients ≥ 18 years old who had a positive urine culture with no documented signs or symptoms of urinary tract infection We excluded pregnant women, solid organ transplant patients, patient on active chemotherapy, and patients about to undergo urological surgery. Results: A total of 716 patients with a positive urine culture were screened. Among these, we identified 109 patients with ASB who were included in our study. The rate of inappropriate antibiotic use was 95% during the study period. The implementation of the ASP Program was associated with a significant reduction in the use of carbapenems (P = 0.04) and an increase in the use of cephalosporins (P = 0.01). However, overprescribing antimicrobial agents was a concern in both eras. Approximately 90% of the microorganisms identified were gram-negative bacteria. Of those, 38.7% were multidrug-resistant strains. Conclusion: The urine culture order in ASB is considered relatively small number; however, it showed a high rate of the inappropriate use of antibiotics when there is an order of urine culture in both era. ASP ought to focus on targeting the ordering physician, promoting awareness and/or organizational interventions that appear to reduce the incidence of overtreatment.

Objectives: The transition of patients from one setting to another increases the risk of medication errors (MEs). This study aims to assess the implementation of pharmacy intern-led transition of care (TOC) service and to demonstrate its impact on the quality of patient care. Method: A prospective interventional pilot study was carried out from August 2020 to April 2021 at an academic hospital in Saudi Arabia. The TOC team consisted of three pharmacy interns and one pharmacist-in-charge. Daily activities included medication reconciliation, discharge counseling, and follow-up call after 3 days of discharge. The identified discrepancies were categorized according to the National Coordinating Council for Medication Error Reporting Program. Key findings: A total of 182 patients were included in the analysis. During medication reconciliation, 102 discrepancies were detected, with an average of 0.7 discrepancy per patient. The most common discrepancy at admission and discharge was omission (41.7% and 70%, respectively). Category B was the most frequent and accounted for 46% at admission and 93% at discharge. Around 39% of TOC beneficiaries received a follow-up call, and all reported a high level of satisfaction with the service. Conclusion: Involving the pharmacy team in TOC activities was effective in identifying discrepancies and resolving MEs.

BACKGROUND: Infection is the second-leading cause of death among cancer patients, but there have been few studies on the effectiveness of novel antimicrobial agents to treat carbapenem-resistant Enterobacterales in cancer patients. OBJECTIVE: Evaluate the mortality and clinical outcomes of ceftazidime-avibactam for OXA-48- and/or New Delhi metallo-beta-lactamase (NDM)-producing Enterobacterales infection in cancer patients. DESIGN: Retrospective observational cohort study SETTING: Tertiary academic medical center in Riyadh, Saudi Arabia SUBJECTS AND METHODS: This study included patients who had cancer and received ceftazidime-avibactam for at least 72 hours for infections caused by OXA-48- and/or NDM-producing Enterobacterales. We excluded patients who died within 72 hours of treatment, patients with polymicrobial infections, and patients who did not receive appropriate antimicrobial therapy. MAIN OUTCOMES AND MEASURES: Primary outcomes were 30-day mortality and hospital mortality. Secondary outcomes included clinical cure, relapse, and reinfection. SAMPLE SIZE: 32 cancer patients RESULTS: The 30-day mortality among all patients was 15/32 (47%), clinical cure was achieved in 19/32 (59%) of the patients, and the relapse and reinfection rates were 2/19 (10.5%) and 4/17 (23.5%), respectively. CONCLUSION: This is the largest study to evaluate clinical outcomes associated with infections caused by OXA-48- and/or NDM-producing Enterobacterales in cancer patients. The mortality rate remains high; ing severe infections in cancer patients.

Purpose: To evaluate the real-world evidence of ceftazidime-avibactam (CAZ-AVI) compared to intravenous colistin for the treatment of multidrug-resistant (MDR) P. aeruginosa infections. Method: This is a multicenter, retrospective cohort study conducted in the period between 2017 and 2023 at five institutions for patients who received either CAZ-AVI or colistin-based regimens for treating MDR P. aeruginosa infections. Outcomes were compared using multivariate logistic regression analysis. Result: Among the screened patients, 203 patients were included: 89 in the CAZ-AVI group and 114 in the colistin group. A total of 57% presented with pneumonia, 21% with bacteremia, and 61% were in the intensive care unit. The rate of clinical cure was significantly higher among patients who received CAZ-AVI (67% vs. 50%; OR, 2.07; 95% CI, 1.16–3.68). The rate of in-hospital mortality was numerically lower among patients who received CAZ-AVI (40% vs. 49%; OR, 0.58; 95% CI, 0.33–1.03). The rate of AKI was significantly lower among patients who received CAZ-AVI (15% vs. 43%; OR, 0.23; 95% CI, 0.11–0.45). Conclusion: CAZ-AVI was more effective in treating MDR P. aeruginosa infections and showed a better safety profile compared to colistin. Thus, CAZ-AVI could be a better alternative for treating MDR P. aeruginosa infections.
