DISCLAIMER: In an effort to expedite the publication of articles, AJHP is posting manuscripts online as soon as possible after acceptance. Accepted manuscripts have been peer-reviewed and copyedited, but are posted online before technical formatting and author proofing. These manuscripts are not the final version of record and will be replaced with the final article (formatted per AJHP style and proofed by the authors) at a later time. PURPOSE: Minimally invasive surgery (MIS) with integrated enhanced recovery pathways (ERPs) helps reduce length of stay and improve surgical outcomes. As these procedures have become more prevalent over time, pharmacists are in key positions to manage medications in the perioperative space to help optimize transitions of care and reduce safety events. Here we identify several clinical areas across phases of care for these procedures in which the knowledge and guidance of pharmacists, as members of the interprofessional team, are paramount. SUMMARY: Perioperative pharmacy expertise is often required for MIS procedures in the areas of acid suppression, antithrombotic management, blood glucose control, drug formulation, immunosuppressant optimization, pain mitigation, and postoperative nausea and vomiting prevention and treatment. For each MIS procedure, pharmacists should identify and consider diet and anatomical changes as well as patient- and surgery-specific risk factors. Pharmacists can then utilize their knowledge of the pharmacokinetics and pharmacodynamics of individual medications along with evidence-based medicine to recommend selection of appropriate agents. CONCLUSION: Pharmacist contributions to perioperative medication management for MIS procedures can improve care as surgical patients navigate transitions through the perioperative setting. Pharmacists can further incorporate medication expertise through development and implementation of institutional MIS protocols within the context of ERPs. As such, any pharmacist should feel empowered to aid in the care of surgical patients.

Insulin Dose Adjustment Following Bariatric Surgery, a Review of Available Literature.

Bariatric surgery is a known and effective treatment for type 2 diabetes mellitus. Patients with type 1 diabetes mellitus and exogenous insulin-requiring type 2 diabetes mellitus require adjusted insulin dosing after surgery to avoid hypoglycemia. This review describes insulin dose adjustments following a variety of bariatric procedures. After searching the available literature and assessing for eligibility, 8 articles were included. The Johns Hopkins Research Evidence Appraisal Tool for literature appraisal was used. The results of this review reveal insulin dose adjustment varies based upon surgical procedure type and time of follow-up from the procedure.

Examining Social Identities of Patient Diversity Through Cases Presented in a Therapeutics Course Series.

Objective. In pharmacy education, considerable debate surrounds the decision about whether didactic cases should include social identities, such as race, ethnicity, sexual orientation, gender identity, ability, spirituality, nationality, and socioeconomic status. In considering what and how much of these identities to include, the first step could be to measure their current inclusion. This study aimed to quantify the presence of these social identities in cases presented to student pharmacists in a three-semester course series.Methods. One hundred forty-four cases presented in a three-semester pharmacotherapeutics course series were reviewed. The primary objective was to quantify the inclusion of each social identity. The secondary objective was to assess whether the identities were needed to answer specific questions related to each case. Cases were reviewed by two independent study researchers; a third impartial reviewer settled disagreements.Results. Cases rarely explicitly included social identities. Race was explicitly stated in 15% of cases (n = 21). Gender identity was explicitly named in two cases (1%), but nearly all cases implied gender through pronouns. Gender was necessary to answer case questions in approximately 20% of cases (n=27). Socioeconomic status, ability, sexual orientation, and nationality were infrequently named among all cases, at rates of 6%, 5%, 1%, and 1%, respectively.Conclusion. This study found that didactic cases rarely explicitly state social identities. In determining the next steps for integrating social identities, pharmacy education must first take stock of how it currently acknowledges these identities.

Incidence of a negative hidden curriculum, cynicism, and burnout within pharmacy resident education: A nationwide survey.

INTRODUCTION: The term "hidden curriculum" (HC) is a set of ethical, moral, and value-based teachings communicated in a non-explicit manner. Recent literature has described increasing awareness of the prevalence of the HC and potential negative impact on medical learners; however, this information is lacking in pharmacy resident education. Consequently, we conducted a survey study of United States pharmacy residents to learn their perceptions concerning the HC in pharmacy residency training. METHODS: A nationwide survey of pharmacy residents was conducted in June 2019. The survey assessed the following: presence of negative HC (score 0 to 80), cynicism (score 0 to 25), burnout via Maslach Burnout Inventory depersonalization (MBI-D) (range 0 to 30), and emotional exhaustion via Maslach Burnout Inventory emotional exhaustion (MBI-EE) (range 0 to 54). Higher scores represent increased occurrences of each domain. RESULTS: The mean HC score was 20 (SD 14.7), mean cynicism score was 9 (SD 5.5), MBI-D was 5.5 (SD 4.5), and MBI-EE was 24.2 (SD 12.4). Of those completing an MBI score, 40.4% (82/203) reported burnout in one area, while 15.8% (32/203) reported burnout in both areas. Residents reporting burnout had higher mean HC and cynicism scores. CONCLUSIONS: Awareness to develop and grow cultures that minimize the presence of a negative HC is essential to improve postgraduate pharmacy training.

Estrogen-induced gallstone pancreatitis in a transgender female.

PURPOSE: The case of a transgender female who developed gallstone pancreatitis in the context of estrogen use for gender-affirming hormone therapy is reported. SUMMARY: A 24-year-old Caucasian transgender female presented to the emergency department for abdominal pain and vomiting after referral from urgent care for suspected pancreatitis. Her home medications included estradiol, medroxyprogesterone, and spironolactone for gender-affirming hormone therapy and omeprazole for reflux. The patient reported minimal alcohol intake, presented with mildly elevated triglyceride levels, and did not have a family history of pancreatitis or gallstone disease. She underwent a laparoscopic cholecystectomy on hospital day 4 and was given a postoperative diagnosis of chronic cholecystitis, cholelithiasis, and pancreatitis. Given her history and the present illness, the use of estrogen therapy is a likely risk factor for the development of gallstone pancreatitis. CONCLUSION: Estrogen is a cornerstone of gender-affirming hormone therapy used by transgender women; however, in addition to its role in gender identity confirmation, estrogen can result in drug-induced pancreatitis.

Systematic review of perioperative use of immunosuppressive agents in patients undergoing bariatric surgery.

BACKGROUND: Patients who qualify for bariatric surgery are increasingly experiencing co-morbid conditions, which often require management through the use of immunosuppressive agents, such as corticosteroids, tumor necrosis factor-alpha inhibitors, or other immunomodulators, which may increase the risk of infection or wound healing complications. Perioperative management of these agents in bariatric surgery is challenging because of the lack of research in this patient population. With the use of immunosuppressive agents on the rise, the effects of these medications must be understood, both the risks posed in the perioperative period, and the benefit their sustained use may have for co-morbidity management. OBJECTIVES: To describe the safety of immunosuppressive agents prior to bariatric surgery. SETTING: United States of America. METHODS: A systematic review was conducted to answer these questions about commonly encountered immunosuppressive agents. This review includes information from 37 studies to present recommendations and reasoning for the discontinuation and postoperative reinitiation of immunosuppressive agents including, tumor necrosis alpha factor-a inhibitors, methotrexate, and more. RESULTS: Research addressing complications of these medications in patients undergoing bariatric surgery is sparse. Information from abdominal or general surgical complications may serve as a basis for conservative recommendations. Data specific to each agent or class are presented below. CONCLUSIONS: The use of these agents may be critical for patients' chronic disease management, and the consequences of their impact should be considered by bariatric surgeons. While their immune system effects ultimately lead to disease management, each agent must be handled individually due to the varying effects and the potential for perioperative untoward effects.

Scopolamine Use in the Perioperative Patient: A Systematic Review.

Scopolamine is an antiemetic agent used for postoperative nausea and vomiting prevention; however, it has anticholinergic effects (eg, bradycardia, dry mouth, dizziness, visual disturbances). Avoiding scopolamine use in specific populations is crucial to prevent adverse effects and harm to patients. This systematic review describes the anticholinergic effects of scopolamine in perioperative patient populations. After searching the available literature, we reviewed the eligible articles to determine whether they met the inclusion criteria (eg, full text, English language, included a discussion of scopolamine's anticholinergic effects in perioperative patients). Twenty-six articles were included in this review. We used The Johns Hopkins Research Evidence Appraisal Tool to appraise the literature. The results of this literature review reveal that clinicians should avoid administering scopolamine to certain perioperative patient populations (ie, pediatric, older adult).

A Randomized Pharmacokinetic and Pharmacodynamic Evaluation of Every 8-Hour and 12-Hour Dosing Strategies of Vancomycin and Cefepime in Neurocritically ill Patients.

PURPOSE: Neurocritically ill patients have clinically significant alterations in pharmacokinetic parameters of renally eliminated medications that may result in subtherapeutic plasma and cerebrospinal fluid antibiotic concentrations. METHODS: We conducted a prospective randomized open-label study of adult neurocritically ill patients treated with vancomycin and cefepime. Vancomycin 15 mg/kg and cefepime 2 g were dosed at every-8- or 12-hour intervals. The primary outcomes were the achievement of pharmacodynamic (PD) targets related to time of unbound drug above minimum inhibitory concentrations (MIC) for 60% or more of the dosing interval (fT > MIC ≥ 60%) for ß-lactams and ratio of 24-hour area under the curve (AUC):MIC of 400 or greater for vancomycin. RESULTS: Twenty patients were included in the study. They were divided equally between the every-12-hour and every-8-hour dosing groups. Patients (mean age 51.8 ± 11 yrs) were primarily male (60%) and white (95%), and most had an admission diagnosis of intracranial hemorrhage (80%). Compared with the every-12-hour group, the every-8-hour vancomycin group achieved target trough concentrations (higher than 15 µg/ml) significantly more frequently at initial measurement (0% vs 80%, p<0.01) and at 7-10 days (0% vs 90%, p=0.045) and achieved PD targets more frequently at increasing MICs. Similarly, compared with every-12-hour dosing, the every-8-hour cefepime dosing strategy significantly increased PD target attainment (fT > MIC ≥ 60%) at an MIC of 8 µg/ml (20% vs 70%, p=0.02). CONCLUSIONS: This study demonstrated that more frequent dosing of vancomycin and cefepime is required to achieve optimal PD targets in adult neurocritically ill patients. The need for increased total daily doses is potentially secondary to the development of augmented renal clearance.

Our own worst enemy: pharmacologic mechanisms of hypertension.

Drug-induced hypertension is often an unrecognized cause of resistant or secondary hypertension. It is defined as hypertension resulting from the unintended effect of a drug or from a drug's antagonistic effect on antihypertensive medications. The main mechanisms of drug-induced hypertension, when categorized broadly, include volume retention and sympathomimetic effects. These mechanisms along with management strategies will be further discussed in this article.

Proton pump inhibitors and histamine-2 receptor antagonists in the intensive care setting: focus on therapeutic and adverse events.

INTRODUCTION: Histamine-2 receptor antagonists (H2RA) and proton pump inhibitors (PPI) are frequently used to prevent stress-related mucosal bleeding (SRMB). A paucity of data implicates these agents with pneumonia and Clostridium difficile infection (CDI). AREAS COVERED: This review comparatively evaluates the effectiveness of H2RAs and PPIs and delineates their associations with these infectious complications. A literature review through 30 September 2014 was performed. EXPERT OPINION: The rate of SRMB is declining, likely due better resuscitation strategies and the early provision of enteral nutrition. Therefore, gastric acid-suppressing therapies arguably reduce SRMB. However, they may contribute to pneumonia and CDI. The risks of these infectious complications depend on the extent of acid suppression and may vary by patient population. PPIs are associated with the greatest hazard for these infections, likely because they provide stronger acid suppression. Intermittent administration of H2RAs has theoretical advantages over continuous H2RA or PPI therapies as this dosing strategy does not fully suppress gastric acid and may limit infection risk. Placebo-controlled studies are warranted because clinical equipoise exists as the detrimental outcomes of these infections may outweigh the benefit of preventing SRMB given the infrequent occurrence of SRMB.
