Impact of Student Pharmacist State Anxiety on Vasopressor Calculation Accuracy in Advanced Cardiac Life Support Simulations

OBJECTIVE

To assess the impact of student pharmacist state anxiety on vasopressor calculation accuracy in advanced cardiac life support (ACLS) simulations.

METHODS

Third-year professional students participated in 2 ACLS-related simulation laboratory sessions. In week 1, students completed 3 calculations at their workstation with no stressors. Students were then randomized into teams for a bedside simulation where they independently completed 3 additional calculations either with or without stressors. Team assignments were maintained for week 2 where all participants completed a high-fidelity ACLS simulation that included a team vasopressor calculation. At both encounters, calculation accuracy was assessed as well as pre- and post-state anxiety using the Spielberger State-Trait Anxiety Inventory (STAI) survey tool.

RESULTS

Students' (N = 145) trait anxiety aligned with normative data for similarly aged professional students. Post-simulation state anxiety in week 1 was found to be higher for those completing the activity with stressors than without (STAI score 44.7 vs 36.9) paired with lower bedside calculation accuracy, despite similar initial workstation calculation accuracy. In week 2, pre-simulation state anxiety score and calculation accuracy were not significantly different between the 2 groups. However, the state anxiety score significantly increased post-simulation for those exposed to stress in the previous week.

CONCLUSION

Stress negatively impacted student pharmacist vasopressor calculation accuracy. However, the repeated exposure to a stressed simulation did not result in a significant difference in pre- or post-simulation state anxiety score or calculation accuracy when compared to a non-stressed control. Consideration should be made whether to include more "real-life" simulations in student pharmacist education.

Prevalence and Value of Board Certification Among Pharmacy Practice Faculty in the United States

OBJECTIVE

To determine the prevalence of board certification among pharmacy practice faculty in the United States, motivators and barriers to certification, and association between board certification and professional achievements and accomplishments that may support career advancement.

METHODS

In phase I, the prevalence of board-certified pharmacy practice faculty in the United States was determined by cross-referencing lists of faculty and board-certified pharmacists. In phase II, faculty were stratified by rank and invited to participate in a survey regarding professional characteristics, motivators and barriers to board certification, and professional achievements and accomplishments that may support career advancement for pharmacy practice faculty.

RESULTS

The prevalence of board certification among the 3276 pharmacy practice faculty was 56%. The prevalence was the highest among assistant professors (61%). A total of 746 faculty completed the survey (33% response rate). Of those respondents, 73% reported being currently certified, 23% never certified, and 4% previously certified. Overall, to be recognized as an expert in the field was identified as the most commonly perceived reason faculty obtain board certification (44%). Currently and previously certified faculty ranked the desire to be recognized as an expert in the field as the most common reason they obtained board certification (61%). There was a positive correlation between board certification and certain professional accomplishments.

CONCLUSION

The prevalence of board-certified pharmacy practice faculty has increased since 2011, but motivators and barriers for board certification remain similar. Board certification may support career advancement for pharmacy practice faculty.

Student Pharmacist-Led Basic Life Support Training for High School Students Improves Knowledge and Skill Achievement

Introduction: The performance of bystander cardiopulmonary resuscitation (CPR) improves survival among cardiac arrest victims. Near-peer teaching of Basic Life Support (BLS) may be an effective way to deliver resuscitation education. This article aims to assess the effectiveness of a student pharmacist-led American Heart Association (AHA) BLS course on high school students' knowledge and skill achievement. Methods: Student pharmacists were trained as AHA instructors and delivered BLS certification courses to high school students. Participants completed pre- and post-assessments adapted from the course learning objectives. Skills performance was evaluated using the AHA's standardized forms. Participants completed questions regarding their perceptions of the pharmacist's role in BLS and confidence in pursuing a career in healthcare. Results: There were 321 participants with the majority in 11th or 12th grade (86.6%) and attending public school (99.1%). After completing the training, the mean percentage of correct assessment responses increased from 41.2% to 89% (p <0.0001). All participants correctly performed BLS skills. Most participants strongly agreed or agreed that the course changed their perspective of the pharmacist's role during BLS (74.8%) and increased their confidence in their decision to pursue future careers in healthcare (61.7%). Conclusion: Student pharmacist-led BLS training, using near-peer delivery, improves high school students' knowledge and skill achievement. This strategy promotes high school students' positive perceptions regarding pharmacists and their role in BLS, as well as their confidence in pursuing careers in healthcare.

Optimal energy provision early in ICU stay for critically ill patients receiving parenteral nutrition

BACKGROUND

Literature on optimal energy provision via parenteral nutrition (PN) is limited and the evidence quality is low. The purpose of this study is to determine if there is a difference in outcomes in adult critically ill patients when receiving lower vs higher calorie provision via PN early in intensive care unit (ICU) stay.

METHODS

Adult patients initiated on PN within the first 10 days of ICU stay from May 2014 to June 2021 were included in this retrospective study. The primary outcome was to determine the impact of lower (<20 kcal/kg/day) vs higher (>25 kcal/kg/day) calorie provision on all-cause, in-hospital mortality. Secondary outcomes were to determine the impact of calorie provision on hospital or ICU length of stay and incidence of complications.

RESULTS

This study included 133 patients: a lower calorie provision group (n = 77) and a higher calorie provision group (n = 56). There was a significant difference in all-cause, in-hospital mortality between the lower and the higher calorie provision groups (36.36% and 17.86%, respectively; P = 0.02). However, upon a multivariate analysis of death at discharge, the specific calorie provision group did not affect the probability of death at hospital discharge. The secondary outcomes were not significantly different between groups.

CONCLUSION

When comparing lower calorie provision with higher calorie provision in adult critically ill patients receiving PN early within their ICU stay, there were no differences in outcomes after controlling for significant confounders. Future larger prospective studies should further evaluate optimal caloric provision via PN in this population.

Guidelines for the provision of nutrition support therapy in the adult critically Ill patient: American society for parenteral and enteral nutrition

BACKGROUND

New randomized controlled trials have been conducted since publication of the 2016 ASPEN/SCCM critical care nutrition guideline. This guideline updates recommendations for foundational questions central to critical care nutrition support.

METHODS

The Grading of Recommendations, Assessment, Development and Evaluation (GRADE) process was used to develop and summarize evidence for clinical practice recommendations. Clinical outcomes were assessed for (1) higher vs lower energy dose (2) higher vs lower protein dose (3) exclusive isocaloric PN vs EN (4) supplemental PN (SPN) plus EN vs EN alone (5a) mixed oil lipid injectable emulsions (ILE) vs soybean oil, and (5b) Fish oil (FO) containing ILE vs non-FO ILE. To assess safety, weight based energy intake was plotted against hospital mortality when study heterogeneity precluded meaningful Forest plot inferences.

RESULTS

Between 1/1/2001 and 07/15/2020, 2,320 citations were identified and data were abstracted from 39 trials, including 20,578 participants. Patients receiving FO had decreased pneumonia rates of uncertain clinical significance. Otherwise, there were no differences for any outcome in any question. Due to lack in certainty regarding harm, the energy prescription recommendation was decreased to 12-25kcal/kg/day.

CONCLUSION

No differences in clinical outcomes were identified among numerous nutritional interventions, including higher energy or protein intake, isocaloric PN or EN, supplemental PN, or different ILEs. As more consistent critical care nutrition support data become available, more precise recommendations will be possible. In the meantime, clinical judgment and close monitoring are needed. This paper was approved by the ASPEN Board of Directors.  This article is protected by copyright. All rights reserved.

Advanced cardiac life support certification for student pharmacists improves simulated patient survival

BACKGROUND AND PURPOSE

Basic life support (BLS) and advanced cardiac life support (ACLS) skills performance, as well as simulated patient survival, were compared for student pharmacist teams with and without at least one member with American Heart Association (AHA) ACLS certification.

EDUCATIONAL ACTIVITY AND SETTING

Doctor of pharmacy students in their third professional year completed a high-fidelity mannequin simulation. Within the previous year, 30 of 184 students (16%) completed ACLS certification. Rapid response teams (n = 31) of five to six members were formed through random student assignment. Two AHA instructors recorded and assessed performance using a checklist adapted from the AHA's standardized forms for BLS and ACLS assessment. Teams with and without ACLS certified members were compared for skills performance and simulated patient survival (i.e. correct performance of all BLS and ACLS skills).

FINDINGS

Teams with ACLS certified members (n = 21) were superior to teams without certified members (n = 10) for correct performance of all observed BLS and ACLS skills, including pulse assessment and medication selection for cardiovascular support. For teams who had ACLS certified members, simulated patient survival was 86% higher. The study groups did not differ in their ability to calculate a correct vasopressor infusion rate if warranted.

SUMMARY

BLS and ACLS skills performance were improved by AHA ACLS certification. Additionally, simulated patient survival was improved for teams with students who had at least one ACLS certified member.

Metabolic Complications Occur More Frequently in Older Patients Receiving Parenteral Nutrition

BACKGROUND

The European Society for Clinical Nutrition and Metabolism Guidelines for Parenteral Nutrition in Geriatric Patients state metabolic complications are more frequent in elderly patients. However, literature provides limited information about metabolic complications in older patients receiving parenteral nutrition (PN). Consequently, the purpose of this study was to compare the development of metabolic complications in older vs younger patients receiving PN.

METHODS

Patients receiving PN from May 1, 2014, to February 7, 2017, at Cooper University Hospital were included. Metabolic complications assessed included acid-base disturbances, hepatic complications, hypercapnia, hyperchloremia, hyperglycemia, hypernatremia, hypertriglyceridemia, hypochloremia, hypoglycemia, hypokalemia, hypophosphatemia, and refeeding syndrome.

RESULTS

595 patients were included (older group [≥65 years]: n = 245, median age: 76 years; younger group [<65 years]: n = 350, median age: 53 years]. Certain characteristics were similar between groups (female, 51%; mean body mass index of 28; critically ill, 34%; central PN, 97%; median duration of PN, 7 days; mean energy provision PN, 25.4 kcal/kg/d; mean dextrose infusion rate, 2.31 mg/kg/min). Overall, metabolic complications developed in 58% of patients and occurred more frequently in older vs younger patients (65.7% vs 53.4%; P = .003). Multivariate logistic analysis demonstrated increased odds of metabolic complications in the older group (odds ratio, 1.55; 95% CI, 1.014-2.375).

CONCLUSIONS

Older hospitalized patients are more likely to develop a metabolic complication during their PN course than younger patients. This study heightens awareness that patients of advanced age are subject to metabolic complications; practitioners should anticipate and resolve complications in a timely manner.

Impact of the Time to Initiation of Parenteral Nutrition on Patient Outcomes in Critically Ill Adults

Background:

The optimal time to initiate parenteral nutrition (PN) in critically ill adults in whom enteral nutrition is not feasible is controversial.

Objective:

The objectives were to compare in-hospital mortality and hospital length of stay in patients initiated on PN within 7 days or after 7 days of poor nutrient intake.

Methods:

This single-center, retrospective study included critically ill adult patients who received at least 2 consecutive days of PN during hospitalization from May 2014 to July 2016.

Results:

The median duration of PN (interquartile range) was 8 (5-13) days. In total, 110 patients received PN within 7 days of poor nutrient intake while 49 patients received PN after 7 days of poor nutrient intake. There was no statistically significant difference in in-hospital mortality between groups (29.09% vs 18.37%, P = .1535). Patients initiated within 7 days had a significantly shorter median hospital length of stay than patients initiated after 7 days (20 days vs 27 days, P = .0013). There were 69 patients who were classified as obese. Obese patients initiated within 7 days had a significantly shorter median hospital length of stay than obese patients initiated after 7 days (17 days vs 33 days, P = .0007).

Conclusions:

Time to initiation of PN did not impact in-hospital mortality. However, there was an association between early initiation of PN and a shorter hospital length of stay that was most pronounced among obese patients.

Impact of Implementation of the American Society for Parenteral and Enteral Nutrition Model for Parenteral Nutrition Order Writing and Review on Competency, Attitudes, and Perceptions

BACKGROUND

The American Society for Parenteral and Enteral Nutrition (ASPEN) parenteral nutrition (PN) safety consensus recommendations advise a comprehensive education program and competency assessment for all healthcare professionals involved in the care of patients receiving PN. The ASPEN-model papers provide guidance for designing PN competencies for prescribers, pharmacists, and pharmacy technicians. The purpose of this research was to evaluate the impact of a comprehensive educational program that aligns with the ASPEN model on PN competency, attitudes, and perceptions in a multidisciplinary healthcare professional audience.

METHODS

Dietitians, pharmacists, and physicians attended a 3-hour ASPEN model-based educational program focused on PN order writing and review. Matched preeducation and posteducation competency assessments were completed by attendees. Attitudes and perceptions were also assessed before and after the educational program using 5-point Likert scales.

RESULTS

Ninety-seven subjects were included in the analysis. The majority of attendees were dietitians (53.6%), followed by pharmacists (45.4%). Overall, multidisciplinary competency assessment scores improved by an average of 12.6% (preassessment average of 62.7%, postassessment average of 75.3%, P < 0.0001). Nine out of 10 statements regarding PN attitudes and perceptions significantly improved on the 5-point Likert scales (P < 0.05).

CONCLUSION

A comprehensive PN educational program in alignment with the ASPEN model positively impacted multidisciplinary healthcare professional PN competency, attitudes, and perceptions. To optimize patient safety, local organizations and institutions should implement formalized training as outlined by the ASPEN model for healthcare professionals involved in the care of patients receiving PN.

Student-Led Cardiopulmonary Resuscitation Education to Lay Providers Results in Successful Knowledge Acquisition and Skill Performance

AIMS

To assess outcomes associated with student-led lay-responder cardiopulmonary resuscitation (CPR) education to community members.

METHODS

Healthcare students (87% pharmacy) were trained as American Heart Association (AHA)-certified CPR instructors and delivered CPR certification programs for the community through the AHA's Heartsaver® CPR Automated External Defibrillator (AED) certification course from August 2016 to January 2017. Knowledge acquisition was evaluated using 5 pre/ post-course questions adapted from the AHA Basic Life Support (BLS) certification course to be consistent with the AHA Heartsaver® CPR AED course learning objectives. Skill performance was evaluated using the AHA's standardized form for adult, child, and infant CPR assessment.

RESULTS

The majority of community member participants (n=105) were female (71%), African American (71%), 45-64 years of age (46%), employed (71%), college educated (50%), and had previous CPR training (63%). Participants demonstrated 100% success rate in correctly performing CPR skills. The mean percentage of correct responses increased from 36% for the pre-course questions to 85% for the post-course questions (p<0.001).

CONCLUSION

Healthcare students successfully provided CPR education to community members who then correctly demonstrated adult, child, and infant CPR skills. Data suggest that student-led CPR training has a positive impact on knowledge acquisition in community members.

Performance and retention of basic life support skills improve with a peer-led training program

BACKGROUND AND PURPOSE

Pharmacy students' performance and retention of Basic Life Support (BLS) skills were evaluated 120 days after completion of a peer-led BLS training program.

EDUCATIONAL ACTIVITY AND SETTING

This was a single-center, parallel group, observational study. Doctor of pharmacy (PharmD) students in their third professional year completed a peer-led BLS training program (n = 148) and participated in a high-fidelity mannequin simulation activity 120 days later. Students were randomly assigned to rapid response teams (n = 24) of five to six members and the American Heart Association's standardized form for BLS assessment was used to assess BLS skills performance. The performance of skills was compared to that of students two years prior to the implementation of the peer-led BLS program.

FINDINGS AND DISCUSSION

Students who received peer-led BLS training demonstrated retention of BLS skills 120 days after the BLS training program. The teams also displayed significant improvement of the skills evaluated when compared to student teams prior to implementation of the peer-led training (n = 22). Improvement was demonstrated for assessment of responsiveness (96% vs. 41%, p < 0.001), assessment for breathing (100% vs. 32%, p < 0.001), assessment for pulse (96% vs. 36%, p < 0.001), and administration of appropriate ventilation (100% vs. 32%, p < 0.001). Numerical superiority was exhibited for high-quality cardiopulmonary resuscitation (CPR) initiation by teams who received peer-led training (100% vs. 86%, p = 0.101).

SUMMARY

Students who received peer-led BLS training demonstrated significant improvement in BLS skills performance and retention 120 days after the training program. Data suggests that peer-led BLS training can improve student BLS skills performance and retention.

Intravenous Vancomycin Associated With the Development of Nephrotoxicity in Patients With Class III Obesity

Background:A consensus statement recommends initial intravenous (IV) vancomycin dosing of 15-20 mg/kg every 8- 24 hours, with an optional 25- to 30-mg/kg loading dose. Although some studies have shown an association between weight and the development of vancomycin-associated nephrotoxicity, results have been inconsistent. Objective: To evaluate the correlation between incidence of nephrotoxicity associated with weight-based IV vancomycin dosing strategies in nonobese and obese patients. Methods: This retrospective cohort study evaluated hospitalized adult patients admitted who received IV vancomycin. Patients were stratified into nonobese (body mass index [BMI] <25 kg/m2), obesity class I and II (BMI 30-39.9kg/m2), and obesity class III (BMI≥40 kg/m2) groups; patients who were overweight but not obese were excluded. Incidence of nephrotoxicity and serum vancomycin trough concentrations were evaluated. Results: Of a total of 62 documented cases of nephrotoxicity (15.1%), 13 (8.7%), 23 (14.3%), and 26 (26.3%) cases were observed in nonobese, obesity class I and II, and obesity class III groups, respectively ( P=0.002). Longer durations of therapy ( P<0.0001), higher initial maintenance doses in both total milligrams/day ( P=0.0137) and milligrams/kilogram ( P=0.0307), and any trough level >20 mg/L ( P<0.0001) were identified as predictors of development of nephrotoxicity. Concomitant administration of piperacillin/tazobactam, diuretics, and IV contrast were associated with development of nephrotoxicity ( P<0.005, all). Patients with class III obesity were 3-times as likely to develop nephrotoxicity when compared with nonobese patients (odds ratio [OR]=2.99; CI=1.12-7.94) and obesity class I and II patients (OR=3.14; CI=1.27-7.75). Conclusions: Obesity and other factors are associated with a higher risk of vancomycin-associated nephrotoxicity.

Variables Affecting Pharmacy Students' Patient Care Interventions during Advanced Pharmacy Practice Experiences

Objective. To identify the temporal effect and factors associated with student pharmacist self-initiation of interventions during acute patient care advanced pharmacy practice experiences (APPE). Methods. During the APPE, student pharmacists at an academic medical center recorded their therapeutic interventions and who initiated the intervention throughout clinical rotations. At the end of the APPE student pharmacists completed a demographic survey. Results. Sixty-two student pharmacists were included. Factors associated with lower rates of self-initiated interventions were infectious diseases and pediatrics APPEs and an intention to pursue a postgraduate residency. Timing of the APPE, previous specialty elective course completion, and previous hospital experience did not result in any significant difference in self-initiated recommendations. Conclusion. Preceptors should not base practice experience expectations for self-initiated interventions on previous student experience or future intentions. Additionally, factors leading to lower rates of self-initiated interventions on infectious diseases or pediatrics APPEs should be explored.

Significant Published Articles for Pharmacy Nutrition Support Practice in 2014 and 2015

PURPOSE

To assist the pharmacy clinician engaged in nutrition support in staying current with the most pertinent literature.

METHODS

Several experienced board-certified clinical pharmacists engaged in nutrition support therapy compiled a list of articles published in 2014 and 2015 that they considered to be important to their practice. Only those articles available in print format were considered for potential inclusion. Articles available only in preprint electronic format were not evaluated. The citation list was compiled into a single spreadsheet where the author participants were asked to ascertain whether they considered the paper important to nutrition support pharmacy practice. A culled list of publications was then identified whereby the majority of author participants (at least 5 out of 8) considered the paper to be important.

RESULTS

A total of 108 articles were identified; 36 of which were considered to be of high importance. An important guideline article published in early 2016, but not ranked, was also included. The top-ranked articles from the primary literature were reviewed.

CONCLUSION

It is recommended that the informed pharmacist, who is engaged in nutrition support therapy, be familiar with the majority of these articles.

Retention of advanced cardiac life support knowledge and skills following high-fidelity mannequin simulation training

OBJECTIVE

To assess pharmacy students' ability to retain advanced cardiac life support (ACLS) knowledge and skills within 120 days of previous high-fidelity mannequin simulation training.

DESIGN

Students were randomly assigned to rapid response teams of 5-6. Skills in ACLS and mannequin survival were compared between teams some members of which had simulation training 120 days earlier and teams who had not had previous training.

ASSESSMENT

A checklist was used to record and assess performance in the simulations. Teams with previous simulation training (n=10) demonstrated numerical superiority to teams without previous training (n=12) for 6 out of 8 (75%) ACLS skills observed, including time calculating accurate vasopressor infusion rate (83 sec vs 113 sec; p=0.01). Mannequin survival was 37% higher for teams who had previous simulation training, but this result was not significant (70% vs 33%; p=0.20).

CONCLUSION

Teams with students who had previous simulation training demonstrated numerical superiority in ACLS knowledge and skill retention within 120 days of previous training compared to those who had no previous training. Future studies are needed to add to the current evidence of pharmacy students' and practicing pharmacists' ACLS knowledge and skill retention.

Inadvertent exaggerated anticoagulation following use of bismuth subsalicylate in an enterally fed patient receiving warfarin therapy

We report a case of an inadvertent increase in the international normalized ratio (INR) after the addition of bismuth subsalicylate for the treatment of diarrhea in an enterally fed patient receiving warfarin therapy. A 56-year-old Caucasian female presented to the trauma intensive care unit (ICU) with multiple lower extremity fractures. Warfarin was initiated for deep vein thrombosis prophylaxis due to the patient's inability to ambulate. The target INR was 2-3. Continuous intragastric enteral feeding was withheld 1 hour before and 1 hour after intragastric administration of warfarin. Bismuth subsalicylate 30 mL every 4 hours was prescribed for diarrhea. Within 3 days after starting bismuth subsalicylate therapy, the patient's INR increased from 2.56 to 3.54 and minor bleeding was noted from the patient's tracheostomy site. No significant change in warfarin dosage, variability in vitamin K intake, or medications that potentially alter warfarin metabolism were present during the unexpected rise in INR. When the bismuth subsalicylate was discontinued, the patient's INR stabilized into the target range on the same warfarin dose given at the time of the supratherapeutic INR. Salicylate displaces warfarin from plasma protein binding sites and may result in a significant increase in INR secondary to redistribution of warfarin to the free active form. Evaluation of this case report using the Drug Interaction Probability Scale and Naranjo Adverse Drug Reaction Probability Scale yielded scores consistent with a probable adverse drug interaction. Bismuth subsalicylate exaggerates warfarin's anticoagulant response and its concurrent use during warfarin therapy should be avoided.

Terahertz two-dimensional high-Q photonic crystal waveguide cavities

Numerical simulations were used to design a variety of high-Q resonant cavities for integration into a terahertz 2D photonic crystal waveguide. After fabrication, the transmission characteristics of each integrated cavity were explored. These photonic waveguide-coupled cavities demonstrate resonances with linewidths approaching 10 GHz. The results compare favorably to previous observations of rectangular waveguide cavities. Good agreement between the experimental results and the numerical simulations was obtained.

The management of epiglottitis in a small paediatric intensive care unit

The aim of this study was to examine the outcome of epiglottitis in a small paediatric institution. Over the 5 year period October 1986 to September 1991, 44 children (of whom 15 were retrieved) with epiglottitis were admitted to the only paediatric intensive care facility in the Hunter Region. The so-called classical features were often absent. Forty of the 44 children were intubated. The mean length of intubation was 22 h and the mean length of hospital stay was only 2 1/2 days. One child had a respiratory arrest prior to intubation but made a complete recovery; one child had a coexistent submental/submandibular fascial space infection; 16 (36%) had abnormal chest radiographs. Five children had post-extubation stridor with one of these children left with residual hoarseness. Epiglottitis can be managed safely in a small paediatric intensive care unit with acceptable short-term and long-term complications.
