Purpose: Neutropenia is an uncommon adverse effect associated with prolonged vancomycin therapy. Methods: This was a case report on a 62-year-old African American male with hypertension, paranoid schizophrenia, and a history of polysubstance abuse developed foot osteomyelitis. The patient was initially maintained on intravenous Vancomycin & Ceftriaxone for ~3 weeks but adjusted to Daptomycin & Ceftriaxone while in hospital due to neutropenia. Patient's neutropenia quickly resolved once discontinuation of Vancomycin occurred. Results: Vancomycin is a potential cause of drug induced leukopenia and neutropenia. Monitoring of leukocytes and neutrophils is warranted in patients receiving long term intravenous Vancomycin therapy. Conclusion: Vancomycin is a bactericidal glycopeptide antibiotic with activity against gram-positive organisms such as Staphylococci. Well-known adverse drug events include nephrotoxicity and ototoxicity. Vancomycin-induced neutropenia on the other hand is less common and reported at lower rates. It is defined as an ANC less than 1000 µL in patients maintained on Vancomycin infusions. According to Black et al, neutropenia is more likely associated with prolonged therapy; generally occurring at least 20 days after initiation.

Background: Inappropriate antibiotic use is a major public health concern. Excessive exposure to antibiotics results in the proliferation of multidrug-resistant bacteria, increase in potentially avoidable adverse drug reactions, healthcare utilization, and cost. Currently, systematic reviews and controlled trials assessing the effects of antimicrobial stewardship programs (ASP) on hospital length of stay (LOS), mortality, and cost-savings are conflicting. Some studies reported a significant cost-savings driven by shorter hospital LOS while the others found no effect and, in some cases, prolonged LOS. Shortening the time to appropriate therapy and reducing unnecessary days of therapy have been shown to reduce hospital LOS. Objective: The purpose of this study was to evaluate the effects of prescriber acceptance to ASP interventions on hospital LOS. Methods: Between January 2018 and December 2019, 764 charts were retrospectively reviewed for patients who received antimicrobial treatment and in whom an ASP intervention was performed. Patients were allocated into 2 groups: those whose ASP interventions were accepted and those whose were rejected. Provider responses were then documented within 24 hours of being communicated. The primary outcome was hospital LOS. Secondary outcomes included 30-day readmission rates and inpatient antimicrobial duration of therapy (DOT). Results: There were 384 patients with an accepted ASP intervention and 380 with a denied intervention. Baseline characteristics were similar between both groups, except for a difference in the types of intervention performed (P < 0.001). The median hospital LOS for patients in the accepted intervention group was 6.5 days compared to 7 days in the rejected intervention group (P = 0.009). Antimicrobial DOT was also shorter in the accepted intervention group (5 vs 7 days; P < 0.001). There was no difference in 30-day readmission rates (P = 0.98). Conclusion: Prescriber acceptance to ASP interventions decreases hospital LOS and antimicrobial DOT without affecting 30-day readmission rates.

Objective: To assess the magnitude of generic-generic and brand-generic medication switching and its impact on patients' understanding and the potential risk of medication errors. Methods: The study composed of 2 parts. The first part is a retrospective study to measure the frequency of medications switching in King Faisal Specialist Hospital and Research Centre (KFSH&RC), from 1^st of January 2015 to the 31^st of December, 2020. Brand medications that were switched to generic medications, generic medications that were switched to brand medications and generic medications that were switched to other generic medications were included. Medications that were switched before or after the study period were excluded. The primary outcomes are the total percentage of switching from brand to generic of all medications in KFSH&RC drug formulary, frequency of generic-generic medications switching and percentage of switching back from generic to brand medications. The second part is a cross sectional survey-based study to assess patients' understanding of their medications and the potential for medication errors by assessing their ability to identify the discrepancies and duplications utilizing a validated questionnaire. Results: Over 5 years, the number of generic medications increased from 553 (35.5%) to 640 (41.1%) out of the 1554 formulary items. Percentage of switching from brand to generic over that 5-year period was 15.9%. Percentage of switching back from generic to brand was 12.8%. Total number of generic medications that had been switched to other generic medications was 256 (16.5%). Out of the 218 patients who had been switched from generic to generic medication, only 43 patients (19.7%) knew the indication for the generic medication they were taking. One hundred forty-six patients (67%) knew the indication of generic medications exclusively by their physical "trademark" characteristics, with 11.5% unrecognized duplication. Conclusion: There is a clear tendency to switch brand medications to generics and to switch between generics. We found the percentage of subsequent switching back to branded products is alarming. Frequent switching between medications negatively impacted patient comprehension and resulted in medication duplication. There is a crucial need for appropriate medication counseling and medication use ecosystem redesign.

Background: Hemophilia treatment centers (HTC) are multidisciplinary clinics that serve as medical homes for patients with hemophilia and other bleeding or clotting disorders. Traditionally, hemophilia treatment center teams have included hematologists, social workers, nurse coordinators, physical therapists, and in some instances, other healthcare professionals. Objective: This report describes the role of clinical pharmacy services added at 2 HTCs. Method: Retrospective review of services provided by pharmacists integrated into the care team conducted at 2 HTCs. Conclusions: Pharmacists have the knowledge and training to positively contribute to the care of hemophilia treatment center patients. Specifically, with expertise in therapeutic drug monitoring, pharmacokinetics and patient counseling, pharmacists have the ability to manage the cost of care by promoting adherence, minimizing emergency department visits, and assisting providers in formulating optimal treatment plans to improve care for this patient population.

Introduction: Drug-drug interactions (DDIs) can reduce therapeutic efficacy and increase the duration and cost of hospitalization so that patients are sometimes exposed to significant complications and even death. Patients in the intensive care unit (ICU) are at higher risk of DDIs for a variety of reasons, including impaired absorption, decreased metabolism, and renal failure. The main objective of this study was to evaluate frequency, clinical ranking and risk factors of potential DDIs in the ICUs of 3 teaching hospitals in Ardabil. Methods: In this descriptive-analytical cross-sectional study, drug prescriptions 355 patients admitted to the ICUs were studied. Patient information including age, sex, diagnosis, number of prescribers, number of drugs, length of stay, and status of patients' discharge (recovery or death) were recorded and checked using the online software up to date and the book Drug Interaction Facts. Finally, the data were statistically analyzed using the SPSS software. Results: The number of patients studied was 355. The mean age of the patients were 51.88 ± 23.22 years, and on average, 8.45 drugs had been prescribed for each patient. The total number of DDIs was 1597 among which class X was 1.4%, class D was 26.2%, and class C was 67.7%. Four hundred ninety-seven unique pairs of DDIs were identified. Age, number of prescribed drugs and length of stay in ICU were associated with prevalence of DDIs. Age and number of drugs were also identified as the risk factors of patients' discharge caused by death. Conclusion: DDIs can complicate health state of patients in ICUs and may increase the length of hospital stay. Setting up computerized systems to alert drug interactions in hospital wards and pharmacotherapeutic intervention by clinical pharmacist can minimize DDIs.

Background: Postoperative nausea and vomiting (PONV) is a common complication following surgery. Only a few risk factors have consistently been reported to be independent predictors for PONV.

Aim: To report Apfel scores for orthopedic patients then correlate these scores to the number of antiemetics prescribed and subsequently administered in both the perioperative and post operative setting and determine if screening for Apfel scores is beneficial to predict PONV.

Methods: A retrospective analysis of patients admitted under orthopedic units between 1st July 2020 and 31st July 2020 was conducted at a tertiary teaching hospital in Australia. Patients were screened and allocated an Apfel score and antiemetics agents prescribed and subsequently administered were recorded.

Results: A total of 115 patients were screened for inclusion. Of these 4 patients met this exclusion criteria, resulting in a total sample size of 111 patients. An Apfel score of 2 was reported in 45.0% of patients, followed by 28.8% of patients scoring 3, with 12.6% scoring one. Only 5.4% of patients scored the highest risk of 4, with 8.2% of patients with no Apfel score documented.

Conclusion: Orthopedic patients tend to score 2 or more in their Apfel score placing them at higher risk of postoperative nausea and/or vomiting according to the collectively validated Apfel's simplified risk score. There was no statistically significant relationship between the Apfel score and the number of antiemetic agents prescribed or administered from both the perioperative and post-operative setting following orthopedic surgery in this cohort of adult patients.

Purpose: Early post-traumatic seizures occur within 7 days following a traumatic brain injury and may lead to additional brain damage and poor outcomes. Levetiracetam or phenytoin is often used for seizure prophylaxis in this patient population, but valproic acid may be an appropriate therapeutic alternative in patients with concomitant agitation. Evidence for the use of valproic acid for both early post-traumatic seizure prophylaxis and agitation is limited. The purpose of this study is to examine the safety and efficacy of valproic acid for both early post-traumatic seizure prophylaxis and agitation. Methods: This single-center, retrospective case series includes 18 patients who received valproic acid for both early post-traumatic seizure prophylaxis and agitation. Efficacy for early post-traumatic seizure prophylaxis is assessed by the incidence of seizures within 7 days of injury. Efficacy for agitation is assessed by changes in Riker Sedation-Agitation Scale scores during valproic acid therapy. The safety of valproic acid is defined by the incidence of selected adverse events. Results: Among 18 patients with traumatic brain injuries receiving valproic acid for both early post-traumatic seizures and agitation, one patient experienced a seizure during the period of prophylaxis and thrombocytopenia was the most common adverse event. Conclusion: In this small cohort of patients, valproic acid appears be a potential option to prevent early post-traumatic seizures in patients with traumatic brain injuries and concomitant agitation with minimal adverse effects. Randomized, controlled studies are needed to further investigate the role of valproic acid for this indication, including standards for dosing regimens, serum drug monitoring, and the relationship between valproic acid treatment and mortality.
