Clinical Trials


  • Left Atrial Pressure Monitoring to Optimize Heart Failure Therapy Not Recruiting

    The purpose of this clinical study is to evaluate the safety and clinical effectiveness of use of a physician-directed, patient self-management system, guided by left atrial pressure measurements, for use in patients with heart failure. The system allows patients to adjust their HF medications daily based on a physician-directed prescription plan and their current HF status, similar to the manner in which diabetes patients manage their insulin therapy. The goal of the LAPTOP-HF study is to demonstrate reductions in episodes of worsening heart failure (HF) and hospitalizations in patients who are managed with the left atrial pressure (LAP) management system (treatment group) versus those who receive only the current standard of care (control group).

    Stanford is currently not accepting patients for this trial.

  • The Effect of Night Float Rotation on Resident Sleep, Activity, and Well-Being. Anesthesia and analgesia Ruan, A., Klein, A., Jhita, P., Hasan-Hill, N., Shafer, S. L., Flood, P. D. 2022

    Abstract

    BACKGROUND: Night float call systems are becoming increasingly common at training programs with the goal of reducing fatigue related to sleep deprivation and sleep disturbance. Previous studies have shown that trainees obtain less sleep during the night float rotation and have decreased sleep efficiency for several days after the rotation. The impact on physical and emotional well-being has not been documented.METHODS: Twenty-seven anesthesia residents were enrolled in a study using wearable sleep and activity trackers and National Institutes of Health Patient-Reported Outcome Measurement Information System (NIH PROMIS) surveys for sleep disturbance, fatigue, and positive affect to record data the week before ("baseline"), during ("night float"), and 1 week after ("recovery") their night float rotation. Each subject's data during the night float week and recovery week were compared to his or her own baseline week data using a paired, nonparametric analysis. The primary outcome variable was the change in average daily sleep hours during the night float week compared to the baseline week. Average daily rapid eye movement (REM) sleep, daily steps, and NIH PROMIS scores comparing night float and recovery weeks to baseline week were prespecified secondary outcomes. NIH PROMIS scores range from 0 to 100 with 50 as the national mean and more of the construct having a higher score.RESULTS: There was no difference in average daily sleep hours between the night float and the baseline weeks (6.7 [5.9-7.8] vs 6.7 [5.5-7.7] hours, median [interquartile range]; P = .20). Residents had less REM sleep during the night float compared to the baseline weeks (1.1 [0.7-1.5] vs 1.4 [1.1-1.9] hours, P = .002). NIH PROMIS fatigue scores were higher during the night float than the baseline week (58.8 [54.6-65.1] vs 48.6 [46.0-55.1], P = .0004) and did not return to baseline during the recovery week (51.0 [48.6-58.8], P = .029 compared to baseline). Sleep disturbance was not different among the weeks. Positive affect was reduced after night float compared to baseline (39.6 [35.0-43.5] vs 44.8 [40.1-49.6], P = .0009), but returned to baseline during the recovery week (43.6 [39.6-48.2], P = .38).CONCLUSIONS: The residents slept the same number of total hours during their night float week but had less REM sleep, were more fatigued, and had less positive affect. All of these resolved to baseline except fatigue, that was still greater than the baseline week. This methodology appears to robustly capture psychophysiological data that might be useful for quality initiatives.

    Abstract

    OBJECTIVE: The purpose of this study was to elicit perspectives from operating room (OR) personnel on the workplace culture and learning climate in the surgical suite, and to identify behaviors associated with a positive culture and learning climate.DESIGN: Qualitative analyses using survey methodology.SETTING: Main hospital OR suite at a large academic medical center.PARTICIPANTS: Nurses, faculty, and residents who work in the OR suite.RESULTS: To improve the OR environment, survey respondents (n = 60) recommended: (1) promoting a respectful "no blame" culture; (2) promoting social cohesion and cross-collaboration; (3) improving communication regarding performance feedback and patient safety; (4) building small interdisciplinary teams working toward common goals; and (5) improving learning opportunities that support professional growth.CONCLUSIONS: Opportunities exist to improve the OR workplace culture and thereby the learning environment.
