RESUMO

BACKGROUND: The purpose of this study was to examine the impact of ARC on levetiracetam concentrations during the first week following acute TBI. The hypothesis was levetiracetam concentrations are significantly lower in TBI patients with augmented renal clearance (ARC) compared to those with normal renal clearance. METHODS: This is a prospective cohort pharmacokinetic study of adults with moderate to severe TBI treated with levetiracetam during the first week after injury. Serial blood collections were performed daily for analysis of levetiracetam, cystatin C, and 12-hr creatinine clearance (CrCl) determinations. Patients were divided into two cohorts: with (CrCl ≥130 ml/min/1.73 m2) and without ARC. RESULTS: Twenty-two patients with moderate to severe TBI were included. The population consisted primarily of young male patients with severe TBI (mean age 40 years old, 68% male, median admission GCS 4). Each received levetiracetam 1000 mg IV every 12 h for the study period. ARC was present in 77.3% of patients, with significantly lower levetiracetam concentrations in ARC patients and below the conservative therapeutic range (< 6mcg/mL) for all study days. In patients without ARC, the serum concentrations were also below the expected range on all but two study days (Days 4 and 5). Four of the 22 (18.2%) patients exhibited seizure activity during the study period (two of these patients exhibited ARC). Cystatin C concentrations were significantly lower in patients with ARC, though the mean for all patients was within the typical normal range. CONCLUSIONS: ARC has a high prevalence in patients with moderate to severe TBI. Levetiracetam concentrations after standard dosing were low in all TBI patients, but significantly lower in patients with ARC. This study highlights the need to consider personalized drug dosing in TBI patients irrespective of the presence of ARC. CLINICAL TRIAL REGISTRATION: This study was registered at cliicaltrials.gov (NCT02437838) Registered on 08/05/2015, https://clinicaltrials.gov/ct2/show/NCT02437838 .

RESUMO

BACKGROUND: Since the release of ChatGPT, numerous positive applications for this artificial intelligence (AI) tool in higher education have emerged. Faculty can reduce workload by implementing the use of AI. While course evaluations are a common tool used across higher education, the process of identifying useful information from multiple open-ended comments is often time consuming. The purpose of this study was to explore the use of ChatGPT in analyzing course evaluation comments, including the time required to generate themes and the level of agreement between instructor-identified and AI-identified themes. METHODS: Course instructors independently analyzed open-ended student course evaluation comments. Five prompts were provided to guide the coding process. Instructors were asked to note the time required to complete the analysis, the general process they used, and how they felt during their analysis. Student comments were also analyzed through two independent Open-AI ChatGPT user accounts. Thematic analysis was used to analyze the themes generated by instructors and ChatGPT. Percent agreement between the instructor and ChatGPT themes were calculated for each prompt, along with an overall agreement statistic between the instructor and two ChatGPT themes. RESULTS: There was high agreement between the instructor and ChatGPT results. The highest agreement was for course-related topics (range 0.71-0.82) and lowest agreement was for weaknesses of the course (range 0.53-0.81). For all prompts except themes related to student experience, the two ChatGPT accounts demonstrated higher agreement with one another than with the instructors. On average, instructors took 27.50 ± 15.00 min to analyze their data (range 20-50). The ChatGPT users took 10.50 ± 1.00 min (range 10-12) and 12.50 ± 2.89 min (range 10-15) to analyze the data. In relation to reviewing and analyzing their own open-ended course evaluations, instructors reported feeling anxiety prior to the process, satisfaction during the process, and frustration related to findings. CONCLUSIONS: This study offers valuable insights into the potential of ChatGPT as a tool for analyzing open-ended student course evaluation comments in health professions education. However, it is crucial to ensure ChatGPT is used as a tool to assist with the analysis and to avoid relying solely on its outputs for conclusions.

RESUMO

BACKGROUND: A growing body of literature describes teaching practices that are positively associated with student achievement. Observing, characterizing, and providing feedback on these teaching practices is a necessary, yet significant challenge to improving teaching quality. This study describes the design, implementation, and evaluation of an instructional coaching program created to provide formative feedback to instructors based on their use of evidence-based teaching practices. METHODS: The program was designed for formative purposes utilizing an instrument adapted from the Teaching Practices Inventory. All faculty were invited to participate in the program on a voluntary basis when the program launched in Fall 2019. Program coaches included any School personnel who completed required training. Two rounds of instrument development were conducted with multiple observers and assessed using Krippendorff's Alpha. The program was evaluated using an anonymous post-session survey. RESULTS: Interrater reliability of the form improved over two rounds of piloting and no differences were found in scoring between trainees and education professionals. Seventeen observations were completed by nine coaches. Instructors indicated that feedback was practical, timely, specific, and collegial, suggesting that including student perspectives (e.g., focus groups, student course evaluations) in the coaching program might be helpful. CONCLUSIONS: Creating programs that emphasize and foster the use of evidence-based teaching are critical for health professions education. Additional research is needed to further develop coaching programs that ensure teaching practices in the health professions are optimizing student learning.

RESUMO

BACKGROUND: Obtaining an accurate estimation of renal function is germane to optimizing care in critically ill patients. However, there is no consensus on the most accurate renal function assessment to utilize in this patient population, particularly in aneurysmal subarachnoid hemorrhage (aSAH) patients. Thus, the objective of this observational study was to determine the comparability of renal function equations to body surface area (BSA)-adjusted 8-h creatinine clearance (CrCl) in aSAH patients. METHODS: A PubMed search investigated the applicability of various renal function equations in critically ill patient populations. A subset of these equations was compared to BSA-adjusted 8-h CrCl from a previous study with aSAH patients with no evidence of renal dysfunction (admission serum creatinine < 1.5 mg/dL) and no history of chronic kidney disease. Area-under-the-curve (AUC) calculations were completed using serial laboratory measurements to validate preliminary findings. RESULTS: A total of 14 renal function equations were identified with seven carried forward for further analysis based upon a priori criteria. Seven equations were excluded for various reasons, including lack of available clinical data, redundancy with other equations, and dissimilar patient populations to this study. When directly compared to the BSA-adjusted 8-h CrCl, only the Cockcroft-Gault and BSA-adjusted Cockcroft-Gault equations were not statistically significantly different (P = 0.0886 and P = 0.4805, respectively); all other equations were statistically significantly different (P < 0.0001). Additionally, only 52% and 44% of patients had average values within 20% of the BSA-adjusted 8-h CrCl using the Cockcroft-Gault and BSA-adjusted Cockcroft-Gault equations, respectively. Finally, the AUC calculations corroborated the preliminary findings with similar results in statistical testing for the Cockcroft-Gault and BSA-adjusted Cockcroft-Gault (P = 0.6300 and P = 0.1513, respectively). CONCLUSIONS: The Cockcroft-Gault equation may be the best renal function equation to assess in critically ill patients diagnosed with aSAH. However, accuracy and consistency in assessing renal function when compared to the BSA-adjusted 8-h CrCl were lacking. Thus, this study suggests the BSA-adjusted 8-h CrCl may be the most appropriate assessment of renal function in patients with aSAH.

RESUMO

OBJECTIVES: To evaluate enhanced renal clearance over time in patients with aneurysmal subarachnoid hemorrhage or intracerebral hemorrhage via measured creatinine clearance and to compare measured creatinine clearance to creatinine clearance calculated by the Cockcroft-Gault equation and estimated glomerular filtration rate calculated by the Modification of Diet in Renal Diseases equation. DESIGN: Prospective, observational study. SETTING: Neurosciences ICU in a tertiary care academic medical center. PATIENTS: Study participants had an admission diagnosis of aneurysmal subarachnoid hemorrhage or intracerebral hemorrhage, an expected neurosciences ICU length of stay greater than 48 hours, no evidence of renal dysfunction (admission serum creatinine < 1.5 mg/dL), and no history of chronic kidney disease. INTERVENTIONS: Eight-hour urine collections to measure creatinine clearance were collected daily as the primary method of measuring renal function. Creatinine clearance was also calculated using the Cockcroft-Gault equation and estimated glomerular filtration rate was calculated using the Modification of Diet in Renal Disease equation. Enhanced renal clearance was defined as a measured creatinine clearance greater than the calculated creatinine clearance via Cockcroft-Gault and estimated glomerular filtration rate via Modification of Diet in Renal Disease. Augmented renal clearance was defined by a measured creatinine clearance greater than or equal to 130 mL/min/1.73 m. Relevant demographic, clinical, and outcome data were recorded. MEASUREMENTS AND MAIN RESULTS: Fifty aneurysmal subarachnoid hemorrhage patients and 30 intracerebral hemorrhage patients were enrolled, contributing 590 individual measurements. Patients with aneurysmal subarachnoid hemorrhage had a higher mean measured creatinine clearance compared with the mean calculated creatinine clearance based on the Cockcroft-Gault equation (147.9 ± 50.2 vs 109.1 ± 32.7 mL/min/1.73 m; p < 0.0001) and higher mean measured creatinine clearance compared with the mean calculated estimated glomerular filtration rate based on the Modification of Diet in Renal Disease equation (147.9 ± 50.2 vs 126.0 ± 41.9 mL/min/1.73 m; p = 0.04). Ninety-four percent of participants with aneurysmal subarachnoid hemorrhage experienced augmented renal clearance on at least 1 day. In patients with intracerebral hemorrhage, there was a higher mean measured creatinine clearance over the study period compared with the mean calculated creatinine clearance (119.5 ± 57.2 vs 77.8 ± 27.6 mL/min/1.73 m; p < 0.0001) and higher mean measured creatinine clearance compared with the mean calculated estimated glomerular filtration rate based on the Modification of Diet in Renal Disease equation (119.5 ± 57.2 vs 93.0.0 ± 32.8 mL/min/1.73 m; p = 0.02). Fifty percent of participants with intracerebral hemorrhage experienced augmented renal clearance on at least 1 day. CONCLUSIONS: A substantial group of patients with aneurysmal subarachnoid hemorrhage or intracerebral hemorrhage experienced enhanced renal clearance, which may be otherwise unknown to clinicians. Enhanced renal clearance may lead to increased renal solute elimination over what is expected, resulting in subtherapeutic renally eliminated drug concentrations. This may result in underexposure to critical medications, leading to treatment failure and other medical complications.

RESUMO

BACKGROUND: Despite widespread recognition of the need for innovative pharmacy practice approaches, the development and implementation of value-based outcomes remains difficult to achieve. Furthermore, gaps in the literature persist because the majority of available literature is retrospective in nature and describes only the clinical impact of pharmacists' interventions. OBJECTIVE: Length of stay (LOS) is a clinical outcome metric used to represent efficiency in health care. The objective of this study was to evaluate the impact of pharmacist-driven interventions on LOS in the acute care setting. METHODS: A separate samples pretest-posttest design was utilized to compare the effect of pharmacist interventions across 3 practice areas (medicine, hematology/oncology, and pediatrics). Two time periods were evaluated: preimplementation (PRE) and a pilot period, postimplementation of interventions (POST). Interventions included targeted discharge services, such as discharge prescription writing (with provider cosignature). Participating pharmacists completed semistructured interviews following the pilot. RESULTS: A total of 924 patients (466 PRE and 458 POST) were included in the analysis. The median LOS decreased from 4.95 (interquartile range = 3.24-8.5) to 4.12 (2.21-7.96) days from the PRE versus POST groups, respectively ( P < 0.011). There was no difference in readmission rates between groups (21% vs 19.1%, P = 0.7). Interviews revealed several themes, including positive impact on professional development. Conclusion and Relevance: This pilot study demonstrated the ability of pharmacist interventions to reduce LOS. Pharmacists identified time as the primary barrier and acknowledged the importance of leaders prioritizing pharmacists' responsibilities. This study is novel in targeting LOS, providing a value-based outcome for clinical pharmacy services.

RESUMO

BACKGROUND: Traumatic brain injury (TBI) is associated with secondary complications, including infection, and patients with TBI often exhibit augmented renal clearance (ARC). This phenomenon has been associated with subtherapeutic levels of renally cleared drugs such as vancomycin, which is dosed based on body weight and creatinine clearance (CrCl). Many clinicians, however, cap CrCl at 120 mL/min/1.73 m2 when calculating vancomycin dosing regimens. We hypothesize that capping patient CrCl, as opposed to utilizing the non-capped CrCl, when determining vancomycin dosing schemes results in subtherapeutic serum trough concentrations in patients with TBI. METHODS: This was a retrospective study of adult patients with TBI admitted between April 2014 and December 2015 who received vancomycin. Population-based pharmacokinetic (PK) parameters using non-capped calculated CrCl and capped CrCl were compared with patient-specific PK parameters based on serum trough concentrations. RESULTS: Thirty-two patients with TBI were included in the study. ARC was suspected in 24 (75%) patients due to a median estimated CrCl at serum trough concentration of 167.3 (127.7-197.7) mL/min. The mean dosing regimen was 17.1 (13.2-19.2) mg/kg every 8 (8-8) h. There was no difference between the median measured trough concentration and predicted value using non-capped CrCl [10.4 (7.1-15.0) vs. 11.5 (7.8-13.7) mcg/mL; p = 0.7986]. The median measured trough concentration was significantly lower than the predicted trough concentration when calculated based on capping the CrCl at 120 mL/min/1.73 m2 [16.3 (15.3-22.0) vs. 11.5 (7.8-13.7) mcg/mL; p < 0.0001]. CONCLUSIONS: Patients with traumatic brain injury appeared to exhibit augmented renal clearance, leading to subtherapeutic vancomycin serum trough concentrations when doses were calculated using the traditional method of capping creatinine clearance at 120 mL/min/1.73 m2. Instead, utilizing patients' non-capped creatinine clearance when determining a vancomycin dosing regimen is more accurate and provides a better estimation of vancomycin pharmacokinetics and could be applied to other renally excreted medications.

RESUMO

BACKGROUND: Early-onset pneumonia (EOP) after endotracheal intubation is common among critically ill patients with a neurologic injury and is associated with worse clinical outcomes. METHODS: This retrospective cohort study observed outcomes pre- and post-implementation of an EOP prophylaxis protocol which involved the administration of a single dose of ceftriaxone 2 g around the time of intubation. The study included patients ≥ 18 years who were admitted to the University of North Carolina Medical Center (UNCMC) neuroscience intensive care unit (NSICU) between April 1, 2014, and October 26, 2016, and intubated for ≥ 72 h. RESULTS: Among the 172 patients included, use of an EOP prophylaxis protocol resulted in a significant reduction in the rate of microbiologically confirmed EOP compared to those without prophylaxis (7.4 vs 19.8%, p = 0.026). However, EOP prophylaxis did not decrease the combined incidence of microbiologically confirmed or clinically suspected EOP (32.2 vs 37.4%, p = 0.523). No difference in the rate of late-onset pneumonia (34.6 vs 26.4%, p = 0.25) or virulent organism growth (19.8 vs 14.3%, p = 0.416) was observed. No difference was observed in the duration of intubation, duration of intensive care unit (ICU) stay, duration of hospitalization, or ICU antibiotic days within 30 days of intubation. In hospital mortality was found to be higher in those who received EOP prophylaxis compared to those who did not receive prophylaxis (45.7 vs 29.7%, p = 0.04). CONCLUSIONS: The administration of a single antibiotic dose following intubation may reduce the incidence of microbiologically confirmed EOP in patients with neurologic injury who are intubated ≥ 72 h. A prophylaxis strategy does not appear to increase the rate of virulent organism growth or the rate of late-onset pneumonia. However, this practice is not associated with a decrease in days of antibiotic use in the ICU or any clinical outcomes benefit.

RESUMO

Drug dosing in neurocritically ill patients presents enormous challenges for clinicians due to the complex pathophysiological alterations. These alterations are dynamic both between and within patients. Unpredictable exposure from standard dosing regimens, which were extrapolated to intensive care unit patients from healthy volunteer studies, may influence medication outcomes. Knowledge of potential alterations in pharmacokinetics/pharmacodynamics in these patients could be applied to maximize the clinical response and minimize adverse effects. Recognizing potential confounding clinical and treatment factors affecting drug response is an important step, but it is not enough. Overcoming absorption and distribution challenges by using specialized formulations and delivery systems is an area of active research. Improved methods for measuring drug concentrations in clinical settings across different matrices are also needed. Even with these advances, defining endogenous mediators signaling drug-target activation is necessary. Identifying biomarkers in disease and changes when a drug has reached its target will be pivotal. This information will improve our understanding of the pharmacogenomic and pharmacokinetic variables affecting pharmacodynamic endpoints across a spectrum of neurologic diseases.

RESUMO

BACKGROUND: Infections are a common medical complication in hemorrhagic stroke patients, with vancomycin commonly used as empiric therapy. The purpose of this study was to evaluate the pharmacokinetic parameters of vancomycin in hemorrhagic stroke patients. METHODS: This was a retrospective study of adult patients with aneurysmal subarachnoid hemorrhage (aSAH) or intracerebral hemorrhage (ICH) admitted between May 2010 and February 2015 who received vancomycin. Predicted pharmacokinetic parameters based on population data were compared with calculated pharmacokinetic parameters based on serum trough concentrations. RESULTS: Eighty aSAH patients and 66 ICH patients met inclusion criteria. In the aSAH group, the mean dosing regimen was 17.6 ± 4 mg/kg every 12 (8-12) h. The mean measured trough concentration was lower than the predicted trough concentration (9.9 ± 4.1 vs. 19 ± 8.7 µg/mL; p < 0.001). The mean calculated elimination rate constant was higher than the predicted value (0.135 ± 0.04 vs. 0.092 ± 0.03 h(-1); p < 0.001), and the mean calculated half-life was lower than predicted (5.7 ± 1.8 vs. 8.3 ± 2.9 h; p < 0.001). In the ICH group, the mean dosing regimen was 15.9 ± 4.3 mg/kg every 12 (8-12) h. Similarly, the mean measured trough concentration was lower than the predicted trough concentration (10.7 ± 4.6 vs. 17.5 ± 8.5 µg/mL; p < 0.001). The mean calculated elimination rate constant was higher than the predicted value (0.106 ± 0.03 vs. 0.079 ± 0.02 h(-1); p < 0.001), and the mean calculated half-life was lower than predicted (7.2 ± 2.3 vs. 9.6 ± 3.2 h; p < 0.001). CONCLUSIONS: Patients with hemorrhagic stroke exhibited pharmacokinetic alterations favoring increased elimination of vancomycin when compared to predicted pharmacokinetic parameters based on population data. This may result in underexposure to vancomycin, leading to treatment failure and other medical complications.

RESUMO

BACKGROUND: Therapeutic strategies that cause an alteration in patient temperature, such as controlled normothermia (CN), therapeutic hypothermia (TH), and pentobarbital infusion (PI), are often used to manage complications caused by acute brain injury. The purpose of this study was to evaluate pharmacokinetic (PK) parameters of vancomycin in patients with acute brain injury undergoing temperature modulation. METHODS: This was a retrospective cohort study of adult patients with acute brain injury admitted between May 2010 and March 2014 who underwent CN, TH, or PI and received vancomycin. Predicted PK parameters based on population data were compared with calculated PK parameters based on serum concentrations. RESULTS: Seventeen CN patients and 10 TH/PI patients met inclusion criteria. Traumatic brain injury and aneurysmal subarachnoid hemorrhage accounted for the majority of admitting diagnoses. In the CN group, the median dose was 16.7 (15.5-18.4) mg/kg. The median calculated elimination rate constant [0.155 (0.108-0.17) vs. 0.103 (0.08-0.142) hr(-1); p = 0.04] was significantly higher than the predicted value. The median measured trough concentration [8.9 (7.7-11.1) vs. 17.1 (10.8-22.3) υg/mL; p = 0.004] was significantly lower than predicted. In the TH/PI group, the median dose was 15.4 (14.7-17.2) mg/kg. No significant differences were found between the median calculated and predicted elimination rate constant [0.107 (0.097-0.109) vs. 0.112 (0.102-0.127) hr(-1); p = 0.41] and median measured and predicted trough concentration [14.2 (12.7-17.1) vs. 13.1 (11-17.8) υg/mL; p = 0.71]. CONCLUSION: Patients who underwent TH/PI did not exhibit PK alterations when compared to predicted PK parameters based on population data, while patients who underwent CN experienced PK alterations favoring an increased elimination of vancomycin.

RESUMO

Hepatitis C is the leading indication for liver transplantation in the USA and recurrence is universal. The impact of preexisting diabetes, new-onset diabetes after transplant (NODAT), and glycemic control on fibrosis progression has not been studied. This retrospective longitudinal cohort study included adult liver recipients with hepatitis C transplanted between 2000 and 2011. Patients were divided into three groups: preexisting diabetes (n = 41), NODAT (n = 59), and no diabetes (n = 103). Patients with preexisting diabetes (70%) or NODAT (59%) were more likely to develop hepatitis C recurrence (≥stage 1 fibrosis), as compared to non-diabetics (36%, p = 0.006). There was also a trend toward a higher incidence of at least Stage 2 fibrosis (36% and 48% vs. 23%, respectively; p = 0.063). Patients with tight glycemic control had a lower rate of Stage 2 fibrosis development (78% vs. 60%, p = 0.027), while those with good control (<150 mg/dL) also had lower rates of Stage 2 fibrosis (84% vs. 62%, p = 0.004). Multivariable analysis verified a decreased rate of recurrence for patients with blood glucose <138 mg/dL (p = 0.021), after controlling for confounders. These results demonstrate that diabetes is strongly associated with an increased risk of hepatitis C virus-related fibrosis development and glycemic control may reduce the risk and severity of recurrence.

RESUMO

PURPOSE: Pharmacy administrators play a critical role in the success of health systems, yet pathways to pharmacy administration are incompletely understood. The purpose of this study was to explore and describe pathways to becoming a health-system pharmacy administrator, including challenges experienced and resources needed. METHODS: Participants (N = 21) individually completed one or more journey maps detailing the pathway(s) to pharmacy administration and then engaged in small group discussion to identify common themes. A large group debrief was used to share and identify findings across small groups. Thematic analysis was utilized to identify common ideas shared. RESULTS: There was variation across the maps, illustrating many steps one might follow to become a pharmacy administrator. In the 23 maps completed, pathways most frequently began with pharmacy school (n = 9, 39.1%), high school (n = 6, 26.1%), or undergraduate training (n = 4, 17.4%). Most included residency training or dual master's of science in health-system pharmacy administration/residency training (n = 16, 69.6%). Common challenges included distractions, time constraints, grades/performance, financial constraints, and stress. Common resources needed included exposure to diverse career paths, pipeline and outreach support, mentoring, and leadership. Themes included debate about the definition of a pharmacy administrator, questions regarding the core competencies of the pharmacy administrator, discussion regarding ways to enter pharmacy administration, and reflection on the role of serendipity and networking. CONCLUSION: Understanding the pathways to pharmacy administration is critical to fostering a sustainable and competent workforce. Work must be done to identify strategies and develop processes for identifying, equipping, and retaining talented health-system pharmacy administrators and leaders.

RESUMO

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: To explore factors influencing career goals and goal attainment for pharmacy learners (eg, students, residents, fellows) who identify as part of the Black, Indigenous, and People of Color (BIPOC) community. METHODS: In late 2021 and early 2022, US-based pharmacy learners were invited to participate in two focus groups. In the first focus group, participants were asked to reflect on career goal influences, barriers, and facilitators. In the second focus group, participants were asked to provide suggestions for educational institutions and healthcare organization improvement to support career goal attainment for learners in the BIPOC community. Focus group transcripts were coded using both deductive and inductive coding and thematic analysis. RESULTS: Fifteen learners were included in the first round of focus group, and 10 learners were included in the second. The most common career goal motivators were self-efficacy factors. Barriers and facilitators were often closely related. The most common barriers were financial, lack of representation, and lack of support. Common facilitators included mentorship and informal networking opportunities. Participants suggested multiple strategies for educational institutions and healthcare organizations to support BIPOC learner success, including genuine investment, representation, financial support, improved access to professional development opportunities, partnering with other professional organizations, and prioritizing diversity, equity, and inclusion (DEI) initiatives. CONCLUSION: Institutions should prioritize effective, positive mentoring relationships and exposure to BIPOC professionals. Training programs and associations should consider improving financial support and lowering the cost of involvement to reduce barriers. All stakeholders should prioritize DEI in their organizational culture to promote career advancement of BIPOC learners and professionals.

RESUMO

Objective. To explore pharmacist alumni perspectives on what topics and how the business of health care should be incorporated into pharmacy school training.Methods. An exploratory sequential mixed-methods design was used. Focus groups were conducted to elicit pharmacist alumni perspectives about business of health care topics and strategies for student learning and curricular implementation. Purposive sampling was used to identify alumni participants who could provide substantive feedback aligned with the needs of this evaluation. Ten alumni attended one of three focus groups over a two-month period. Thematic coding was used to identify themes. Results from the focus groups were used to inform survey development distributed to alumni of the pharmacy school. Survey data were analyzed using descriptive statistics.Results. Findings from the focus groups and survey indicated that the business topics most important for students to learn were communication strategies, health care operations, the health care payer system, managing teams, and career options within pharmacy. Focus group participants recommended a variety of activities to help students learn and apply business topics and emphasized that simulations and real-world experiences were needed to help students learn these topics and assess their understanding. Instructors should be currently or recently employed in the business sector to provide credibility. Barriers to implementation occur at both the student and curricula level.Conclusion. The possession of business skills and knowledge play a critical role in helping the pharmacy profession advance within a dynamic health care environment. Recommendations were provided on key business content important for Doctor of Pharmacy students to learn and strategies to implement within a pharmacy program.

RESUMO

OBJECTIVE: To explore the relationship between pharmacy school admission variables and matching to a postgraduate year 1 (PGY1) pharmacy residency program. METHODS: Demographic data, academic indicators, and application review scores were collected for the 2017-2020 Doctor of Pharmacy (PharmD) graduating classes. Multiple mini-interview (MMI) scores were collected for the 2018-2020 PharmD graduating classes. Postgraduate year 1 matching data were collected for all students. Bivariate analyses were performed comparing students who matched to a PGY1 residency versus those who did not match versus those who did not pursue a residency. Logistic regression modeling was performed to explore predictors of matching to a PGY1 residency program. RESULTS: A total of 616 students were included. Bivariate analyses revealed that students who matched to a PGY1 had a higher undergraduate grade point average, higher pharmacy college admissions test composite score, were younger in age, and were more likely to identify as female. Students who matched also scored higher on MMI stations with constructs related to integrity, adaptability, critical thinking, and why pursuing our school. Logistic regression modeling found that an increase in age was associated with lower odds of matching to a PGY1 (0.88 [0.78-0.99]) and an increase in composite MMI station score was associated with higher odds of matching (1.8 [1.31-2.47]). CONCLUSION: Several pharmacy school admission variables were found to be associated with successful matching to a PGY1 residency. These findings have the potential for impact at a programmatic level when evaluating the weight of certain criteria for admission decisions and at the individual student level when providing career services support.

RESUMO

Objective. To examine and summarize policies and procedures for peer evaluation of teaching/instructional coaching (PET/IC) programs within departments, schools, and colleges of pharmacy and to identify opportunities for improving these based on best practices.Methods. A survey was sent to all Accreditation Council for Pharmacy Education (ACPE)-accredited pharmacy programs to collect information regarding procedures to support and evaluate PET/IC programs across institutions. Descriptive statistics were used to summarize the general features of PET/IC programs, and inferential statistics were used to make group comparisons based on institutional control (public, private) and institution age (0-10 years, older than 10 years).Results. Surveys for 91 institutions were completed (response rate=64.5%). Most institutions (78.4%) reported having a PET/IC program. Most institutions with PET/IC programs reported using a combination of formative and summative evaluations (57.4%). The top purposes for PET/IC programs were faculty development (35.8%) and improving teaching (35.8%). Almost half of the PET/IC programs (46.3%) were mandatory for all faculty at the institutions. Most institutions (66.7%) had one standardized instrument used in their PET/IC program. Few institutions (11.9%) reported evaluating or being in the process of evaluating the effectiveness or success of their PET/IC program. Private institutions were more likely to incentivize observers than public institutions (17.1% vs 0).Conclusion. Overall, PET/IC programs are needed to assess and provide feedback to instructors about their teaching practices. While most institutions report having a PET/IC program, wide variability exists in how the programs are implemented. Opportunities exist for institutions to evaluate the effectiveness of their program and identify best practices.

RESUMO

PURPOSE: The primary aim of this study was to investigate the accuracy of the volumetric method for intravenous (IV) preparations and explore the utility of gravimetric methods in the medication preparation process within multiple institutions. Secondary outcomes of this study were syringe size percent variations and impact on drug expenditures. METHODS: A prospective, noninterventional, multisite study was conducted between March 2015 and December 2016 to generate baseline estimates of accuracy and precision in the volumetric medication preparation process. Five hospitals in the United States were recruited for study participation. During the data collection process, technicians were required to measure the syringe at 3 different points: when the new empty syringe was connected to a closed-system transfer device (CSTD), when the filled syringe containing the prepared dose of medication was connected to a CSTD, and when the used syringe with residual medication was connected to a CSTD. The actual dose of drug dispensed (in mg) was divided by the specific gravity of the medication to determine the actual volume of medication dispensed. RESULTS: A total of 4,443 compounded sterile products representing 60 medications across 5 hospitals were eligible for the study. Of the evaluated preparations, 91.92% were within 5% of the prescribed dose and 96.56% were within 10% of the prescribed dose. The outliers ranged from -144.10% to 233.72%. CONCLUSION: The potential for significant over- and undertreatment of an individual patient receiving IV chemotherapy exists, indicating the need for an additional measurement method, such as real-time gravimetric verification, to ensure an accurate dose is administered to every patient.

RESUMO

This article describes the design, implementation, and evaluation of five faculty development sessions focused on inclusive teaching strategies in pharmacy education. Inclusive strategies ensure that every student can clearly understand and engage in meaningful learning opportunities. Three sessions were implemented in fall 2020 and two in spring 2021. Sessions focused on experiential, didactic, and graduate education. A convergent parallel mixed methods evaluation was conducted using descriptive statistics and thematic analysis. Sessions were highly rated, and participants provided suggestions for curriculum improvement (e.g., creating resources, surveying students, and peer auditing syllabi for aspects of inclusiveness). Given the increasing emphasis on inclusion in pharmacy education, this work is timely for sharing strategies aimed at faculty development and teaching practices.
