Engaging resident physicians in the design, implementation, and assessment of bedside interdisciplinary rounds.

Bedside interdisciplinary rounds (IDR) improve teamwork, communication, and collaborative culture in inpatient settings. Implementation of bedside IDR in academic settings depends on engagement from resident physicians; however, little is known about their knowledge and preferences related to bedside IDR. The goal of this program was to identify medical resident perceptions about bedside IDR and to engage resident physicians in the design, implementation, and assessment of bedside IDR in an academic setting. This is a pre-post mixed methods survey assessing resident physicians' perceptions surrounding a stakeholder-informed bedside IDR quality improvement project. Resident physicians in the University of Colorado Internal Medicine Residency Program (n = 77 pre-implementation survey responses from 179 eligible participants - response rate 43%) were recruited via e-mail to participate in surveys assessing perceptions surrounding the inclusion of interprofessional team members, timing, and preferred structure of bedside IDR. A bedside IDR structure was created based on input from resident and attending physicians, patients, nurses, care coordinators, pharmacists, social workers, and rehabilitation specialists. This rounding structure was implemented on acute care wards in June 2019 at a large academic regional VA hospital in Aurora, CO. Resident physicians were surveyed post implementation (n = 58 post-implementation responses from 141 eligible participants - response rate 41%) about interprofessional input, timing, and satisfaction with bedside IDR. The pre-implementation survey revealed several important resident needs during bedside IDR. Post-implementation survey results revealed high overall satisfaction with bedside IDR among residents, improved perceived efficiency of rounds, preserved quality of education, and value added by interprofessional input. Results also suggested areas for future improvement including timeliness of rounds and enhanced systems-based teaching. This project successfully engaged residents as stakeholders in system-level interprofessional change by incorporating their values and preferences into a bedside IDR framework.

Cardiopulmonary Performance Among Heart Failure Patients Before and After Left Ventricular Assist Device Implantation.

BACKGROUND: Patients with heart failure with reduced ejection fraction (HFrEF) have persistent impairments in functional capacity after continuous-flow left ventricular assist device (CF-LVAD) implantation. OBJECTIVES: This study aims to characterize longitudinal changes in exercise hemodynamics and functional capacity among patients with HFrEF before and after CF-LVAD implantation. METHODS: Ten patients underwent 3 invasive cardiopulmonary exercise tests on upright cycle ergometry with pulmonary artery catheterization: 1) Visit 1 before CF-LVAD implantation; 2) Visit 2 after device implantation with CF-LVAD pump speed held constant at baseline speed; and 3) Visit 3 with increases in pump speed during exercise (median: 1,050 rpm [IQR: 750-1,150 rpm] and 220 rpm [IQR: 120-220 rpm] for HeartMate 3 and HeartWare VAD, respectively). Hemodynamics and direct Fick cardiac output were monitored using pulmonary artery catheterization. Gas exchange metrics were determined using indirect calorimetry. RESULTS: Maximal oxygen uptake (Visits 1, 2, and 3: 10.8 ± 2.5 mL/kg/min, 10.7 ± 2.2 mL/kg/min, and 11.5 ± 1.7 mL/kg/min; P = 0.92) did not improve after device implantation. Mean pulmonary arterial and pulmonary capillary wedge pressures increased significantly during submaximal and peak exercise on preimplantation testing (P < 0.01 for rest vs peak exercise) and remained elevated, with minimal change on Visits 2 and 3 regardless of whether pump speed was fixed or increased. CONCLUSIONS: Among patients with HFrEF, cardiovascular hemodynamics and exercise capacity were similar after CF-LVAD implantation, regardless of whether patients exercised at fixed or adjusted pump speeds during exercise. Further research is needed to determine methods by which LVADs may alleviate the HFrEF syndrome after device implantation.

The influence of gender and oxytocin on stress reactivity, cigarette craving, and smoking in a randomized, placebo-controlled laboratory relapse paradigm.

RATIONALE: Female cigarette smokers tend to show greater cessation failure compared with males. Variables that contribute to the maintenance of smoking, including stress and craving, may differentially impact male and female smokers. Novel pharmacotherapies, such as oxytocin, may attenuate stress reactivity and craving in smokers, but work in this area is limited. OBJECTIVES: This study assessed the influence of gender and oxytocin on stress reactivity, craving, and smoking in a randomized, placebo-controlled laboratory relapse paradigm. METHODS: Male and female adult cigarette smokers (ages 18-45) were enrolled (women oversampled 2:1) and completed a laboratory session, in which intranasal oxytocin or placebo was administered followed by a laboratory social stress task. The role of gender and oxytocin were assessed on measures of stress reactivity, cigarette craving, latency to smoke in a resistance task, subjective responses to smoking, and ad-libitum smoking. RESULTS: Participants (N = 144) had a mean age of 31 were 63% female and 56% White. Following stress induction, female smokers evidenced greater subjective stress than males, though males demonstrated greater neuroendocrine reactivity and smoking intensity than females. No gender differences were demonstrated for craving. Oxytocin did not attenuate any aspect of stress reactivity, craving, smoking, or subjective responses to smoking compared with placebo. CONCLUSIONS: Gender differences in stress reactivity were shown in the hypothesized direction, but oxytocin appeared to exert little impact on subjective or behavioral metrics. Results highlight the complex relationship between gender, stress, and smoking, as well as the implications for oxytocin as a potential pharmacotherapy for smoking cessation.

Tobacco Use Prevalence and Outcomes Among Perinatal Patients Assessed Through an "Opt-out" Cessation and Follow-Up Clinical Program.

Purpose Cigarette smoking in the perinatal period is associated with costly morbidity and mortality for mother and infant, yet many women continue to smoke throughout their pregnancy and following delivery. This report describes tobacco use prevalence among perinatal smokers identified through an "opt-out" inpatient smoking cessation clinical service. Description Adult women admitted to the peripartum, delivery, and postpartum units at a large academic hospital were screened for tobacco use. Smokers were identified through their medical record and referred to a bedside consult and follow-up using an interactive voice response (IVR) system to assess smoking up to 30 days post-discharge. Assessment Between February 2014 and March 2016, 533 (10%) current and 898 (16%) former smokers were identified out of 5649 women admitted to the perinatal units. Current smokers reported an average of 11 cigarettes per day for approximately 12 years. Only 10% reported having made a quit attempt in the past year. The majority of smokers (56%) were visited by a bedside tobacco cessation counselor during their stay and 27% were contacted through the IVR system. Those counselled in the hospital were twice as likely (RR 1.98, CI 1.04-3.78) to be abstinent from smoking using intent-to-treat analysis at any time during the 30 days post-discharge. Conclusions This opt-out service reached a highly nicotine-dependent perinatal population, many of whom were receptive to the service, and it appeared to improve abstinence rates post-discharge. Opt-out tobacco cessation services may have a significant impact on the health outcomes of this population and their children.
