Background: Among critically ill patients receiving mechanical ventilation, Candida spp. are commonly detected in the lower respiratory tract (LRT). This is generally considered to represent colonization.

Objective: To evaluate the use of antifungal treatments and the clinical outcomes of patients with Candida colonization of the LRT.

Methods: This retrospective analysis involved consecutive patients admitted to the intensive care unit between April 2016 and May 2021with positive results on Candida spp. testing of LRT samples. Data related to antifungal treatment and clinical outcomes were analyzed descriptively, and multivariable logistic regression was performed.

Results: Of 200 patients initially identified, 160 (80%) died in hospital. Antifungal therapy was given to 103 (51.5%) of the patients, with treatment being more likely among those with shock and those who received parenteral nutrition. Mortality was high among patients with positive Candida results on LRT culture, regardless of treatment. Multivariable logistic regression, with adjustment for age, sex, comorbidities, and sequential organ failure assessment (SOFA) score, showed that antifungal treatment was associated with lower odds of death (odds ratio 0.39, 95% confidence interval 0.17-0.87) compared with no treatment (p = 0.021).

Conclusions: This study showed higher mortality rates than have been reported previously. Further investigation into the role of antifungal therapy among critically ill patients with Candida spp. colonization is required.

Background: It is hypothesized that international pharmacy graduates (IPGs) are underrepresented in more clinically challenging work.

Objective: To examine the association between country of qualifying education for pharmacists in Ontario and the likelihood of practising in a hospital setting.

Methods: This study was based on publicly available data from the Ontario College of Pharmacists website, specifically records for all Ontario pharmacists with authorization to provide patient care and for whom country of qualifying education and an accredited pharmacy as a place of practice were reported. Pharmacists who met the inclusion criteria were categorized as Canadian graduates or IPGs. The odds ratio (OR) and 95% confidence interval (CI) for reporting hospital pharmacy as a place of practice were estimated by fitting a logistic regression, with adjustment for gender and years since graduation.

Results: A total of 14 689 pharmacists were included in the study: 7403 (50.4%) Canadian graduates and 7286 (49.6%) IPGs. These pharmacists worked in a total of 5028 accredited pharmacies (243 hospital pharmacies [4.8%] and 4785 community pharmacies [95.2%]). Among Canadian graduates, 2458 (33.2%) reported at least 1 hospital pharmacy practice site, whereas the proportion was much smaller among IPGs (427, 5.9%). Canadian graduates represented 85.2% (2458/2885) of all pharmacists who reported hospital practice. The estimated crude OR for practice in a hospital pharmacy was 7.98 (95% CI 7.16-8.91), and the adjusted OR was 7.12 (95% CI 6.39-7.98).

Conclusions: IPGs may face barriers impeding their ability to practise in a hospital setting. Providing opportunities such as structured clinical training and experiential placements may facilitate integration of IPGs in institutional settings.

Background: Current guidelines for the treatment of acute exacerbation of chronic obstructive pulmonary disease (AECOPD) and community-acquired pneumonia (CAP) recommend 5 days of antimicrobial therapy. Despite these recommendations, the duration of therapy exceeds 5 days for up to 70% of patients, with most superfluous prescribing occurring upon discharge from hospital. Shortening the duration of antibiotic therapy could decrease adverse events, resistance, and costs.

Objective: To determine whether a pharmacist-initiated modification to the duration of antibiotic therapy prescribed for the treatment of AECOPD or CAP reduced the duration of antibiotic prescriptions.

Methods: In this prospective, single-centre study of adult inpatients receiving antibiotics for the treatment of AECOPD or CAP between October 2020 and March 2021, pharmacists assigned a 5-day duration to antimicrobials prescribed for these indications. For patients discharged before completion of therapy, the antibiotic start date and intended duration were included on the discharge prescription. Study patients were matched 1:1 with historical controls to compare the total duration of antibiotic therapy with and without the intervention.

Results: A total of 100 patients (66 with CAP and 34 with AECOPD) met the inclusion criteria and had their antibiotic treatment duration modified to 5 days. Mean total duration of antibiotic therapy was 5.31 days in the intervention group and 7.11 days in the control group (p < 0.001). Outpatient antibiotic prescribing was 0.86 days in the intervention group and 3.2 days in the control group (p < 0.001). In both groups, the rates of readmission at 30 and 90 days were 19% and 31%, respectively.

Conclusions: Pharmacist-initiated modification of antimicrobial therapy resulted in shortening of the duration of therapy by almost 2 days. Including information about treatment duration on the discharge prescription reduced outpatient prescribing without affecting readmission rates.

Background: Given altered pharmacokinetics in people with cystic fibrosis (pwCF), there is debate regarding optimal strategies for therapeutic drug monitoring (TDM) for aminoglycosides and vancomycin administered intravenously.

Objectives: To determine the TDM strategy for IV aminoglycosides and IV vancomycin associated with optimal clinical outcomes in pwCF.

Data sources: Several databases (MEDLINE, Embase, CINAHL, Web of Science, Cochrane Central Register of Controlled Trials, and ClinicalTrials.gov ) were searched from inception to November 15, 2020, with searches rerun on February 13, 2023.

Study selection and data extraction: Full articles evaluating TDM strategies and clinical outcomes in pwCF receiving IV aminoglycosides or IV vancomycin were included.

Data synthesis: Three studies met the inclusion criteria for IV aminoglycosides, and 1 study met the inclusion criteria for IV vancomycin. Data are presented with descriptive analyses.

Conclusions: The available evidence is insufficient to determine an optimal TDM strategy for IV aminoglycoside or IV vancomycin therapy in pwCF.
