Pharmacists’ Knowledge About the Impact of Augmented Renal Clearance on Antimicrobial Dosing in Critically Ill Patients: A Cross-Sectional Study

Abstract Background Broad-spectrum antibiotics are commonly prescribed in critically ill patients. While it is commonly believed that only patients with impaired renal function need dose adjustment, augmented renal clearance (ARC) is a phenomenon that warrants dose adjustment as well. In critically ill patients ARC is often undetectable because it is associated with a normal or decreased serum creatinine concentration (SCr). This study’s objective was to assess pharmacists’ knowledge about ARC identification, risk factors, affected antimicrobials, and dosing of antibiotics in patients with ARC. Methods In January 2020, we carried out a cross-sectional study by sending out an online survey to the Saudi Pharmaceutical Society, Kuwait Pharmaceutical Association, and Oman Pharmaceutical Society. Due to the expected low response rate, we administered an electronic questionnaire to pharmacists attending Dubai International Pharmaceuticals and Technologies Conference and Exhibition 2020 (DUPHAT). Results Data were collected from 288 respondents. However, only 134 were included in the final analysis following the exclusion of incomplete responses, no experience working in in-patient settings, and respondents who chose “no” universal ARC definition. Those who chose “yes” or “I do not know” regarding the universal definition of ARC were asked about SCr status in ARC. Elevation in SCr was chosen by 67/134 (50%) compared to those who chose decreased or normal (48/134, 35.8%). Regarding risk factors, only 1/134 (0.7%) respondent selected all risk factors. Two/134 (1.4%) respondents chose all hydrophilic antibiotics that are likely to be affected by ARC. Concerning the appropriate dose and frequency of piperacillin-tazobactam and meropenem, they were selected by 60.4% and 30.5%, respectively. Conclusion Pharmacists’ knowledge about ARC was limited. Implementation of educational programs targeting hospital pharmacists, especially those practicing in critical care settings, and developing antimicrobial institutional guidelines are important

The impact of Saudi Arabia – United States clinical pharmacy post-graduate training programs agreements on clinical pharmacy faculty in Saudi universities: A retrospective descriptive study focused on history and future recommendations

Background: There has been a growing demand for clinical pharmacy services in the Kingdom of Saudi Arabia (KSA) in the past 3 decades. The Ministry of Education has established agreements with several institutions in the United States to secure clinical pharmacy residency and research fellowship programs opportunities for Saudi scholars. The aims of this study were to describe the Saudi scholars’ clinical pharmacy training pathways and their contribution to the pharmacy profession in KSA. Methods: This is a retrospective, descriptive study conducted on clinical pharmacy faculty in governmental Saudi universities who graduated from the US until 2023. The study outcomes included the post-graduate year-1 (PGY-1) residency match rate, post-graduate year-2 (PGY-2) acceptance rate, the PGY-2 specialties of Saudi scholars, and the number of clinical pharmacy programs established in KSA. Results: In total, 115 Saudi scholars have pursued clinical pharmacy pathway in the US. The PGY-1 residency match rate was 80 % (92/115). In contrast, the PGY-2 acceptance rate was 60.9 % (70/115). The most common PGY-2 specialty was in infectious diseases (N = 17; 24 %). Two pharmacy colleges had established residency programs and 1 pharmacy college had established a research fellowship. Conclusion: The Ministry of Education's efforts for clinical pharmacy program agreements were fundamental for advancing clinical pharmacy in Saudi universities. A significant number of Saudi scholars returned to KSA with clinical pharmacy degrees. There are more opportunities for further development, including expanding the clinical pharmacy program collaboration in the US and increasing the number of residency and research fellowship positions in KSA

Effectiveness of antibiotic-loaded bone cement in total joint arthroplasty at a tertiary medical center: A retrospective cohort study

Background: Data regarding the effectiveness of antibiotic-loaded bone cement (ALBC) in preventing prosthetic joint infections (PJI) after total joint arthroplasty (TJA) is inconsistent. The objective of this study was to evaluate if the routine use of ALBC influenced the risk of revision surgery due to PJI. Methods: This is a retrospective cohort study performed between January 2018 and September 2020. Adult patients aged ≥ 18 years who underwent TJA (knee or hip) and received either ALBC or plain cement (PC) were included. The outcome of this study was the rate of revision due to PJI. Multivariate analysis using logistic regression was used to identify factors that may be associated with increased risk of PJI, using STATA 15.1 (StataCorp LP, College Station, Texas, USA). Results: A total of 844 patients were screened and 319 patients were included. There were 247 patients in ALBC group and 72 patients in the PC group. Only vancomycin powder was used in all ALBC cases, with a 2 g dose in 50% of the cases (dose ranged between 1 g and 8 g). The status of the prosthetic joint was assessed and recorded up to 2 years of the TJA. Overall, the difference in the rates of PJI between the two groups after primary arthroplasty was not statistically significant (5.6% vs 1.4%; p = 0.173; OR, 4.2; 95% CI, 0.5–33). Conclusion: ALBC was not associated with a reduction in PJI rates after primary TJA. More research is needed to further evaluate the effectiveness of ALBC in preventing PJI
