The Impact of Electromagnetic Interference from Charging All-electric Vehicles on Implantable Cardioverter-defibrillator Performance.

Electric vehicles (EVs) are growing in popularity and in general use. The effect of electromagnetic interference (EMI) caused by supercharging all-electric vehicles on implantable cardioverter-defibrillator (ICD) function has not been studied. The objective of this study was to determine the extent of the effect of EMI from charging Tesla all-electric vehicles (Tesla, Inc., Austin, TX, USA) on cardiac implantable electronic device function. A proof-of-concept study was performed to explore the potential effect of EMI from Tesla vehicles while charging the battery using a 220-V wall charger and a 480-V Supercharger. Tesla Model S and Model X vehicles were used for this study. We enrolled 34 patients with stable ICD function for the initial phase using the standard wall charger, followed by an additional 35 patients for the second phase using the Supercharger. Tracings were obtained at nominal and highest sensitivity settings while patients sat in the driver's seat, passenger seat, back seats, and facing the charging port. In each position, the device and the patient were monitored in real time by a certified technician for any inappropriate sensing and/or delivery of therapies. A medical magnet was also available on site. Emergency medical services and physician supervision were available at all times, and patients were contacted the following day to ensure their well-being. No device interactions were identified at both the nominal and highest sensitivity settings of each ICD during exposure to vehicle charging using a Tesla 220-V wall charger and a 480-V Supercharger at any of the five positions in and around each vehicle. Interaction was defined as oversensing, undersensing, mode switch, or upper rate tracking behavior. There was also no damage to any ICD, and no inappropriate shocks were administered to any patient. In conclusion, transvenous ICD function is not interrupted by EMI transmitted while charging Tesla vehicles using either the 220-V wall charger or the 480-V Supercharger.

Point-of-care hemoglobin A1c margin of error alters resident management of Type 2 diabetes when near glycemic target.

AIMS: Point-of-care (POC) HbA1c is frequently used as a surrogate for serum HbA1c. We aimed to determine if resident management of type 2 diabetes changed after accounting for the + 0.5% margin of error associated with POC HbA1c devices. METHODS: Residents were surveyed in an outpatient clinic regarding two of their patients with type 2 diabetes for which they had obtained a POC HbA1c. For one patient, the resident was asked if management would change if the POC HbA1c were 0.5% higher (called the positive case), and for another if management would change if POC HbA1c were 0.5% lower (negative case). RESULTS: Twelve of 58 (21%) cases had a change in management. Of the 27 cases where POC HbA1c was near the glycemic target (defined as POC HbA1c ≥6.0% and <8.0%), 11 (41%) resulted in a change in management while one (3%) of the 31 cases outside that interval had a change in management. CONCLUSION: POC HbA1c testing is well-suited for patients with poorly controlled type 2 diabetes while serum HbA1c testing may be more appropriate when near a patient's personalized HbA1c target since small changes in HbA1c can lead to differences in medical management.

Implementation and Evaluation of a Longitudinal Flipped-Classroom Point-of-Care Ultrasound Curriculum at an Internal Medicine Residency Program.

BACKGROUND: Point-of-care ultrasound (POCUS) has extensive clinical utility in internal medicine, but formal and uniform curricula in internal medicine are lacking. OBJECTIVE: To determine the effectiveness of a longitudinal, flipped-classroom, academic half-day curriculum on internal medicine resident confidence, utilization, and changes in clinical management. METHODS: We implemented an asynchronous, flipped-classroom, academic half-day curriculum from November 2020 to November 2021 and conducted an evaluation with a prospective, before-after cohort study. Curriculum included 4 rotating sessions comprised of 20 to 30 min of image interpretation followed by 1.5 to 2 h of image acquisition. Confidence was rated via Likert scale. Utilization was reported via indicating never, 1 to 2, 3 to 4, 5 to 6, or >6 times per month (recorded as 1-5, respectively). Image interpretation was assessed via a 6-question, multiple-choice video assessment. RESULTS: Nineteen of 99 potential residents (19%) completed a pre- and post-curriculum evaluation. Residents attended a median of 4 sessions. Confidence improved from 2.47 to 3.53 (P = .002). Utilization did not improve overall (2.11-2.42, P = .22), but utilization of left ventricular function assessment (1.53-2.00, P = .046) and pulmonary assessment (1.53-2.00, P = .039) increased. The percentage of residents that had ever changed their clinical management by POCUS increased from 47% to 84% after implementation of the curriculum. Cardiac, pulmonary/pleural, volume assessment, and abdominal free fluid exams were reported as the most clinically useful. CONCLUSION: Implementation of a longitudinal, academic half-day curriculum for POCUS resulted in improved confidence, increased POCUS utilization for the cardiac and pulmonary examination, and changes in clinical management based on POCUS.

Improving performance on night shift: a study of resident sleep strategies.

STUDY OBJECTIVES: To identify sleep strategies of internal medicine residents transitioning to night shift and report their effect on performance. METHODS: Residents logged hours of sleep and work starting 3 days prior to the first night shift and continuing through the next 8 days. Cohorts were defined by sleep logs and compared separately by transition strategy, total hours of sleep, amount of sleep occurring at work, weekend sleep schedule, and residency training year. Data from logs were entered into the Fatigue Avoidance Scheduling Tool to measure predicted Performance Effectiveness (PE) during each night shift. RESULTS: Twenty-three residents were evaluated. The Sleep Banking transition strategy (n = 2) had higher PE (mean = 88.6%) than all other sleep strategies combined (n = 21, mean = 80.9%; P = .016). Additionally, residents who slept an average of 8-9 hours daily during their week of night shifts had a higher mean PE compared to those who slept < 6 hours (86.8% vs 78.6%; P = .014). CONCLUSIONS: Residents who engaged in Sleep Banking prior to the first night shift had higher PE and spent less time above a 0.05% blood alcohol concentration equivalent compared to all other strategies. Similarly, PE and time spent above a 0.05% blood alcohol concentration equivalent improved with increased average hours slept per day during the week of night shifts. Optimizing performance on night shift through the adoption of efficacious sleep strategies is imperative to mitigate patient safety issues that may result from poor alertness and cognitive abilities.

Whistling Scrotum: An Unusual Presentation of Pneumomediastinum in the Setting of an Open Scrotal Wound.

BACKGROUND Pneumoscrotum is a rare clinical occurrence in which air accumulates in the scrotum. The origin of air is primarily from trauma, but spontaneous pneumoscrotum can develop from gastrointestinal or pulmonary sources. Physical examination of pneumoscrotum typically includes crepitus of the perineal region and scrotal swelling and associated findings depending on the origin of the free air. However, pneumoscrotum in the setting of a scrotal wound, which allows air to pass freely outside the body, has not been previously documented in the literature. CASE REPORT A 72-year-old man who recently underwent a scrotal incision and drainage for recurrent epididymitis presented to a local emergency room with chief concerns of "whistling scrotum" and dyspnea. The chest CT revealed bilateral pneumothoraces, pneumomediastinum, and excessive subcutaneous emphysema throughout his abdomen, perineum, and scrotum. His scrotum had a dehiscent wound without any gross edema or air trapping contained within the scrotum. He received bilateral chest tubes and subcutaneous air drains with complete resolution of his pneumothoraces. The pneumoscrotum and associated subcutaneous emphysema of the perineum and thighs resolved after a prolonged period, and necessitated additional scrotal surgery. CONCLUSIONS Prompt evaluation for source control is necessary with pneumoscrotum, as the source likely requires immediate stabilization or surgical intervention. This case report describes a unique presentation of a common entity (pneumothorax) within pulmonology/critical care in a patient with an open scrotal wound from a recent scrotal procedure, which allowed the air to escape from his abdominal compartment, and resulted in his "scrotal whistling." It is unclear how the air passing through the scrotum affected the patient's presentation, such as allowing more air to build up in the subcutaneous tissues versus developing critical illness.

Intravenous thrombolysis prior to mechanical thrombectomy does not affect clinical or procedural outcomes in patients with large vessel occlusion acute ischemic stroke.

Mechanical thrombectomy (MT) has revolutionized the care of large vessel occlusion acute ischemic strokes (LVOAIS). However, the benefit of intravenous thrombolysis prior to MT remains unproven. Two recent trials showed equivocal results regarding the benefits of pre-MT intravenous thrombolysis in predominantly Asian populations. We evaluated clinical outcomes and procedural metrics for patients with LVOAIS who were treated with MT alone compared to those who were treated with both intravenous tPA and MT. In a retrospective study, LVOAIS patients treated with MT, with or without preceding intravenous thrombolysis, between January of 2017 and December of 2019 were identified. Patients were treated according to contemporary guidelines. Baseline demographic and clinical characteristics, procedural metrics, and clinical outcomes were collected. Among LVOAIS patients, those treated with intravenous thrombolysis and MT did not differ from those with MT alone on clinical outcomes at three months. Further, the two groups did not differ on thrombectomy procedure times, recanalization rates, and symptomatic intracranial hemorrhage rates. In our patients with LVOAIS, intravenous thrombolysis combined with MT offered no advantage compared to MT alone in clinical outcomes or recanalization rates. Our results are consistent with earlier studies in other populations. In addition, our results suggest that IV tPA does not impact the ease of clot removal by MT. Further studies will evaluate how newly available thrombolytic agents may benefit patients eligible for MT.

Not Your Typical Bisphosphonate Intolerance: A Case of Unusual Bone Pain With Low Alkaline Phosphatase.

Bisphosphonates, first-line medications for osteoporosis, are often not tolerated or discontinued for multiple reasons. Hypophosphatasia (HPP) is a genetic deficiency with the enzyme activity of tissue-nonspecific alkaline phosphatase (TNSALP). The symptoms of adult HPP are often non-specific, and the diagnosis may be delayed for years. Low serum alkaline phosphatase, a hallmark feature of HPP, is often overlooked. Genetic testing is recommended to confirm diagnosis, and treatment with asfotase alfa, a recombinant alkaline phosphatase, is available for patients with HPP. We report a case of HPP in a 71-year-old female with recurrent skeletal pain and bisphosphonate intolerance who ultimately was diagnosed with HPP.

Examining the initial prescription leading to long-term opioid use at a military medical treatment facility.

OBJECTIVE: Chronic pain is common in the military, and over a quarter of active-duty military members have received a prescription for opioids. This study reviewed the initial opioid prescription among those who became future long-term users at an Air Force base in the United States and reports the characteristics of the provider and patient. METHODS: Our single-center retrospective study evaluated initial opioid prescriptions leading to long-term use within the military's electronic medical record at a large military medical treatment facility including active-duty patients and veterans. Of the 3,701 charts reviewed, 348 patients met the inclusion criteria for the long-term opioid use. RESULTS: Older patient groups received a higher initial amount of opioids than younger groups (p = 0.007). Primary care outpatient clinics started 43 percent of initial long-term opioid users, while surgical specialties contributed to 34 percent of the sample. In our study, 35.9 percent of the long-term opioid users were given their first opioid prescription within 30 days of an operation. Veterans or those separated from the military were less likely to have a behavioral disorder than active duty or family members. CONCLUSIONS: Our sample mirrored the civilian population in terms of age, gender, and most common pain diagnosis. We found that older patients initially received a higher dispensed amount compared to our younger patients. There was a concerning trend for surgical patients to develop into chronic opioid users.

Upper Extremity Deep Venous Thrombosis Risk Factors, Associated Morbidity and Mortality in Trauma Patients.

BACKGROUND: The literature on upper extremity deep venous thrombosis (UEDVT) is not as abundant as that on lower extremities. This study aimed to identify the risk factors for UEDVT, associated mortality and morbidity in trauma patients and the impact of pharmacological prophylaxis therein. METHODS: A 3-year retrospective review of patients admitted to a Level 1 trauma center was conducted. Patients aged 18 years or older who had experienced a traumatic event and had undergone an upper extremity ultrasound (UEUS) were included in the study. Multiple logistic regression was used to identify independent risk factors that contributed to UEDVT. RESULTS: A total of 6,607 patients were admitted due to traumatic injuries during the study period, of whom 5.6% (373) had at least one UEUS during their hospitalization. Fifty-six (15%) were diagnosed with an UEDVT, as well as three non-fatal pulmonary emboli (PE) and four (7.1%) deaths, p = 0.03. Pharmacological prophylaxis with low-molecular-weight heparin (LMWH) or unfractionated heparin showed a protective effect against UEDVT; among the patients positive for UEDVT, 14 of 186 patients (7.5%) received LMWH, while 42 of 195 (21.5%) did not receive LMWH (p < 0.001). Multiple logistic regression revealed that the presence of upper extremity fractures, peripherally inserted central catheter (PICC) lines, and traumatic brain injury (TBI) were independent risk factors for UEDVT. CONCLUSIONS: UEDVT are associated with a higher mortality. The presence of upper extremity fractures, PICC lines, and TBI were independent risk factors for UEDVTs. Further, pharmacological prophylaxis reduces the risk of UEDVT.

Reduction of central line-associated bloodstream infections in a large acute care hospital in Midwest United States following implementation of a comprehensive central line insertion and maintenance bundle.

BACKGROUND: Central line-associated bloodstream infection (CLABSI) is a preventable medical condition that results in increased patient morbidity and mortality. We describe the impact of various quality improvement interventions on the incidence of CLABSI in an 848-bed community teaching hospital from 1 January 2013 to 31 December 2017. AIM: To reduce CLABSI rates after implementation of a comprehensive central line insertion and maintenance bundle. METHODS: A comprehensive bundle of interventions was implemented incorporating the standard US Centers for Disease Control and Prevention bundle with additional measures such as root-cause analysis of all CLABSI cases, use of passive disinfection caps on vascular access ports, standardisation of weekly central venous catheter (CVC) site dressing changes, and use of antithrombotic and antimicrobial-coated CVCs with fewer lumens. A retrospective study evaluated CLABSI rates and time of CLABSI onset after CVC placement in both intensive care unit (ICU) and non-ICU settings. RESULTS: The annual number of CLABSI cases declined 68% (34 to 11 patients) from 2013 to 2017. There was a 30% decline in CVC days from years 2014 to 2017. Over the same period, CLABSI cases per 1000 CVC days decreased from 0.624 to 0.362: a 42% decline. CONCLUSION: Following the implementation of a comprehensive bundle of interventions for CVC insertion and maintenance, we found a reduction in rates of CLABSI.

Distress evaluation in a veteran affairs oncology clinic.

Distress in oncology patients (pts) has a negative impact on quality of life, survival, and healthcare satisfaction. Higher distress leads to lower compliance with treatment and follow-up [1-8]. The 2012 American College of Surgeons Commission on Cancer (CoC) standard of care for oncology pts included an assessment for distress [1]. A screening process for distress allows the healthcare team to address these issues early and refer to appropriate resources [2-9]. This project was initiated to meet National Comprehensive Cancer Network (NCCN) and CoC standard of care, identify distress in veterans with cancer, and address these concerns. Patients who attended the Tuesday oncology clinic at the Dayton VAMC were given the NCCN Distress Thermometer (DT) during triage. The treating physician addressed problems identified. The Wilcoxon signed rank test and the Friedman test were used. DTs were completed by 296 pts from March to December 2016. Mean age was 68, 93% male, 83% white, 55% married, and 93% without PTSD. The distress level was not different from T1 through T3. Number of problems decreased over three time periods. Referrals to nutrition, mental health, and social work services increased over time. Although over time periods we found no decrease in distress scores, there was a decline in number of problems. The mean distress score at all but time 4 was < 4, which is considered mild distress. The mean distress score at T4 was 4.36 (n = 14), suggesting that the few pts who return to clinic more than three times may be experiencing more difficult personal and environmental circumstances. Patient sample ranged from those undergoing intensive cancer treatment (e.g., chemotherapy) to less intensive treatment (e.g., hormone injections) to those who completed treatment.

Right Heart Function in Critically Ill Patients at Risk for Acute Right Heart Failure: A Description of Right Ventricular-Pulmonary Arterial Coupling, Ejection Fraction and Pulmonary Artery Pulsatility Index.

BACKGROUND: The gold standard for right heart function is the assessment of right ventricular-pulmonary arterial coupling defined as the ratio of arterial to end-systolic elastance (Ea/Emax). This study demonstrates the use of the volumetric pulmonary artery (PA) catheter for estimation of Ea/Emax and describes trends of Ea/Emax, right ventricular ejection fraction (RVEF), and pulmonary artery pulsatility index (PAPi) during initial 48hours of resuscitation in the trauma surgical intensive care unit (ICU). METHODS: Review of prospectively collected data for 32 mechanically ventilated adult trauma and emergency general surgery patients enrolled within 6hours of admission to the ICU. Haemodynamics, recorded every 12hours for 48hours, were compared among survivors and non-survivors to hospital discharge. RESULTS: Mean age was 49±20 years, 69% were male, and 84% were trauma patients. Estimated Ea/Emax was associated with pulmonary vascular resistance and inversely related to pulmonary arterial capacitance and PA catheter derived RVEF. Seven (7) trauma patients did not survive to hospital discharge. Non-survivors had higher estimated Ea/Emax, suggesting right ventricular-pulmonary arterial uncoupling, with a statistically significant difference at 48hours (2.3±1.7 vs 1.0±0.58, p=0.018). RVEF was significantly lower in non-survivors at study initiation and at 48hours. PAPi did not show a consistent trend. CONCLUSIONS: Estimation of Ea/Emax using volumetric PA catheter is feasible. Serial assessment of RVEF and Ea/Emax may help in early identification of right heart dysfunction in critically ill mechanically ventilated patients at risk for acute right heart failure.

Team-Based Learning in the Surgery Clerkship: Impact on Student Examination Scores, Evaluations, and Perceptions.

OBJECTIVE: There is little evidence for effectiveness of team-based learning (TBL) in specialties such as Surgery. We developed and instituted TBLs in surgery clerkship and compared National Board of Medical Examiners (NBME) Surgery Subject Exam scores before and after implementation. We also analyzed students' feedback for their perception of TBLs. DESIGN, SETTING, AND PARTICIPATNTS: The TBLs were transitioned into the curriculum during the 2013-2014 academic year. The "before" and "after" implementation periods were 2011-2013 and 2014-2016, respectively. NBME Surgery Subject Examination scores at our institution and nationally were compared using the independent samples t test. Satisfaction with the clerkship was assessed with Association of American Medical Colleges Graduate Questionnaire data. Student feedback regarding TBL was gathered at the end of each surgery rotation and were analyzed for themes, both positive and negative. RESULTS: Mean NBME score was higher at our institution than nationally, both before (77.10 ± 8.75 vs. 75.20 ± 8.95, p = 0.032) and after (74.65 ± 8.0 vs. 73.10 ± 8.55, p = 0.071) TBL implementation. The mean score decreased following TBL implementation at our medical school (77.10 ± 8.75 vs. 74.65 ± 8.00, p = 0.039), but it was also lower nationally (75.20 ± 8.95 vs. 73.10 ± 8.55, p < 0.001). Further, students were more likely to rate the surgery clerkship as "good and/or excellent" on the Association of American Medical Colleges Graduate Questionnaire after TBL implementation (84.6% vs. 73.7%). In qualitative assessment, learners stated that TBLs were informative, helpful in studying for the shelf exam, and viewed them as an opportunity for interactive learning, and thus requested more TBLs. Areas for improvement included reading materials, directions, and organization of sessions. CONCLUSIONS: Student perception of TBL into our surgery clerkship has been both positive and provided feedback for improvement. In addition, our medical school graduates have continued to assess their surgery experience as "good" or "excellent" by a large majority. Concurrently, our NBME scores remain above the national mean. We believe our medical students benefit from a well-organized TBL and its active approach to learning during the surgery clerkship with no loss of fundamental surgery knowledge.

Stress Electrocardiography vs Radionuclide Myocardial Perfusion Imaging among Patients Admitted for Chest Pain: Comparison of Teaching and Nonteaching Hospital Services.

OBJECTIVES: The American Board of Internal Medicine Foundation's Choosing Wisely initiative has identified the routine use of stress cardiac imaging among lower-risk patients as an expensive test that should be questioned by both physicians and patients. The objectives of this study were to determine how often patients hospitalized for chest pain are assessed with stress electrocardiography (stress ECG) compared with radionuclide myocardial perfusion imaging (rMPI) and to evaluate whether the cardiac testing guidelines of the American Heart Association and the Choosing Wisely campaign are being followed. We also sought to determine whether there were differences in practice patterns between a teaching and a nonteaching hospital service. METHODS: We conducted a retrospective chart review of 842 consecutive patients admitted with the primary diagnosis of chest pain to a 900-bed university-affiliated teaching hospital in Dayton, Ohio. After exclusions, we analyzed records from 111 teaching service and 94 nonteaching service patients. We assessed whether patients were evaluated with stress ECG or rMPI and compared the teaching service with the nonteaching service. RESULTS: The nonteaching service obtained rMPI more often than the teaching service (94% vs 51%, P < 0.001) and stress ECG less frequently than the teaching service (1% vs 12%, P < 0.003). Both groups may have overused rMPI, choosing it over the less costly alternative of stress ECG testing 71% of the time. CONCLUSIONS: Adherence to the Choosing Wisely recommendations for the appropriate use of stress ECG is suboptimal among both teaching and nonteaching physicians. Choosing stress ECG, when appropriate, could translate into substantial cost savings and reduce potentially harmful radiation exposure.

Prevalence of Cancer in Thyroid Nodules In the Veteran Population.

A 16-year retrospective chart review found no relationship between nodule size and malignancy, emphasizing the need for individualized care.

Global Health Education for Medical Students: When Learning Objectives Include Research.

BACKGROUND: The Luke Commission, a provider of comprehensive mobile health outreach in rural Swaziland, focuses on human immunodeficiency virus testing and prevention, including the performance of over 100 circumcisions weekly. Educational objectives for medical student global health electives are essential. Learning research methodology while engaging in clinical activities reinforces curriculum goals. Medical care databases can produce clinically significant findings affecting international health policy. Engaging in academic research exponentially increased the educational value of student experiences during an international medical elective. METHODS: Staff of the Luke Commission, a nongovernmental organization, collected and deidentified information from 1500 Swazi male patients undergoing circumcision from January through June of 2014. Medical students designed studies and analyzed these data to produce research projects on adverse event rates, pain perception, and penile malformations. Institutional review board approval was obtained from the home institution and accompanying senior surgical faculty provided mentorship. RESULTS: First-year medical students enrolled in an international medical elective to explore resource availability, cultural awareness, health care provision, and developing world endemic diseases. While in country, students learned research methodology, collected data, and engaged in research projects. Following the trip, students presented posters at over 10 regional and national meetings. All 4 articles are accepted or under consideration for publication by major journals. CONCLUSIONS: During international medical electives the combination of clinical experiences and access to databases from health aid organizations provides the foundation for productive medical student research. All participants benefit from the relationships formed by aid organizations, medical students, and patient populations. Global health research has many complexities, but through careful planning and cultural awareness, medical students can increase their research skills and contribute to the medical literature, bringing attention to and improving health care policies around the world. In sum, the educational experience of medical students is enhanced through the interaction of delivering patient care and completing clinical research studies.

Is nasotracheal intubation safe in facial trauma patients?

BACKGROUND: In the prehospital setting, oral intubation is preferred in facial trauma patients due to the potential for further injury during nasotracheal intubation. This study compared the complications of nasal vs. oral vs. nasal + oral intubations performed by first responder crews in facial trauma patients. Our objective was to assess patient outcomes and complications to determine the risk of nasal intubation in facial trauma patients in the prehospital setting. METHODS: Patients with facial trauma between 2008 and 13 were abstracted from the Miami Valley Hospital trauma registry: 50 were nasal only (n), 27 nasal + oral (no), and 135 oral only (o) intubation. Analysis of variance with the post-hoc Least Significance Difference Test and the chi square test were used in the analysis. RESULTS: The oral group was older [41.1 ± 17.6 (o) vs. 36.2 ± 14.1 (n) vs. 33.0 ± 15.7 (no), p = 0.032] and had a higher facial abbreviated injury severity (AIS) mean score (1.8 ± 0.6 vs. 1.3 ± 0.5 vs. 1.5 ± 0.5, p < 0.001). The three groups did not differ in mortality (n = 20% vs. o = 18% vs. no = 30%, p = 0.37). The n + o group was intubated longer (p < 0.001) and had longer ICU and hospital lengths of stay (p = 0.015 and p = 0.023). The three groups did not differ on the composite of any pulmonary complication - i.e., any one of sinusitis, pneumonia, atelectasis, and respiratory failure - 44% (no) vs. 24% (o) vs. 30% (n), p = 0.10). However, nasal + oral patients were more likely to have one or more of the eight complication studied [63% (no) vs. 28% (o) vs. 34% (n), p = 0.002], and have a longer ICU and HLOS. CONCLUSIONS: Prehospital nasal intubation is a viable short-term alternative to oral intubation in patients with facial trauma and warrants further research.

Factors Affecting the Vocational Calling of Laboratory Animal Care and Research Employees.

We surveyed laboratory animal care and research workers to determine the factors affecting their vocational calling. The survey comprised 56 questions in 4 groups: passion, job stability or happiness, work volition, and demographics. We hypothesized that personnel who worked in the field a longer time, were older, had higher education levels, were involved with AALAS, and in higher positions in their organization were more likely to indicate a calling to the laboratory animal care field. In addition, we hypothesized that job satisfaction and classifying one's job as a calling were positively related to organizational support and work volition. Overall, 44% of respondents categorized their work as at least partially a calling. Those working at a higher level in the position of laboratory animal technician and in the organization were more likely to view their work as a calling. Increasing education level was related to work being a calling. Overall, vocational calling was significantly associated with higher pay, but technicians were the only subgroup where calling and higher pay were significantly related. Vocational calling and job satisfaction were associated with organizational support. For our sample of workers in the animal care field, other factors analyzed were not related to work being considered a calling. Leaders in the field of animal care may find our survey results valuable as they strive to adapt their organization's structure to the perceptions of their workforce with regard to their sense of calling.
