Strategies to Assess the Effect of Continuous Positive Airway Pressure on Long-Term Clinically Important Outcomes among Patients with Symptomatic Obstructive Sleep Apnea: An Official American Thoracic Society Workshop Report

Continuous positive airway pressure (CPAP) is the first-line treatment for obstructive sleep apnea (OSA). Although CPAP improves symptoms (e.g., daytime sleepiness), there is a lack of high-quality evidence that CPAP prevents many long-term outcomes, including cognitive impairment, myocardial infarction, and stroke. Observational studies suggest that patients with symptoms may be particularly likely to experience these preventive benefits with CPAP, but ethical and practical concerns limited the participation of such patients in prior long-term randomized trials. As a result, there is uncertainty about the full benefits of CPAP, and resolving this uncertainty is a key priority for the field. This workshop assembled clinicians, researchers, ethicists, and patients to identify strategies to understand the causal effects of CPAP on long-term clinically important outcomes among patients with symptomatic OSA. Quasi-experimental designs can provide valuable information and are less time and resource intensive than trials. Under specific conditions and assumptions, quasi-experimental studies may be able to provide causal estimates of CPAP's effectiveness from generalizable observational cohorts. However, randomized trials represent the most reliable approach to understanding the causal effects of CPAP among patients with symptoms. Randomized trials of CPAP can ethically include patients with symptomatic OSA, as long as there is outcome-specific equipoise, adequate informed consent, and a plan to maximize safety while minimizing harm (e.g., monitoring for pathologic sleepiness). Furthermore, multiple strategies exist to ensure the generalizability and practicality of future randomized trials of CPAP. These strategies include reducing the burden of trial procedures, improving patient-centeredness, and engaging historically excluded and underserved populations.

Impact of a lung ultrasound course for rheumatology specialists (IMPACT-2)

OBJECTIVES

Lung ultrasound (LUS) plays an increasing role in diagnosis and monitoring of interstitial lung disease (ILD). Connective tissue disorders (CTD) frequently cause ILD, and often presents symptomatically after irreversible fibrosis has ensued. As point-of-care musculoskeletal ultrasound (US) is commonly utilised by rheumatologists, translating this US expertise towards LUS places the rheumatologist in a position to screen for ILD. However, a standardised curriculum for the rheumatology community is lacking. The aim of this study is to determine the effectiveness of a formalised lung US training course for rheumatologists.

METHODS

Four rheumatology fellows and four board-certified rheumatologists participated in a 4-hour training session. Pre-course, post-course and 6-month follow-up surveys evaluated perceptions towards previous US experience, training, clinical utility and attitudes toward lung US. Didactics explained the protocols utilised in ILD evaluation. Evaluation of knowledge in US physiology, lung anatomy, artifact and pathology recognition were done through written exams before, after training, and at 6 months and through a practical exam using live models and simulation.

RESULTS

Temporally there was overall improvement in written test scores. Improvement was noted in overall practical skill score following training course (17.4% vs. 92.9%, p<0.001), in written test scores 49.3% vs. 72.5% p<0.001), and pathology identification (26.5% vs. 79.6%, p<0.001). Six-month follow assessments were similar to post-test results revealing similar written scores (70.6%) and practical scores (89.7%).

CONCLUSIONS

This formalised lung ultrasound training course was effective in improving skills and knowledge of rheumatology specialists.

Emerging Roles of Clinical Ethicists

Debates regarding clinical ethicists' scope of practice are not novel and will continue to evolve. Rapid changes in healthcare delivery, outcomes, and expectations have necessitated flexibility in clinical ethicists' roles whereby hospital-based clinical ethicists are expected to be woven into the institutional fabric in a way that did not exist in more traditional relationships. In this article we discuss three emerging roles: the ethicist embedded in the interdisciplinary team, the ethicist with an expanded educational mandate, and the ethicist as a therapeutic presence in the patient care space. Such expanded capacities offer more robust, positive contributions to institutional culture, stakeholders' relationships, and patient-centered care.

Emotional Support for Health Care Professionals: A Therapeutic Role for the Hospital Ethics Committee

Hospital ethics committees (HECs) are typically charged with addressing ethical disputes, conflicts, and dilemmas that arise in the course of patient care. HECs are not widely viewed as having a therapeutic role for health care professionals who experience psychological distress or anticipatory grief in the course of discharging professional duties. A case is presented in which an ethics consultation was requested, chiefly, to secure emotional support for health care professionals who had been asked by a patient to discontinue life-sustaining treatments. As the case demonstrates, HECs may be called upon to provide emotional support and reassurance to health care professionals who willingly carry out psychologically difficult actions, even though these actions may be ethically uncontroversial. In providing this service, the HEC may not necessarily engage in its customary activity of deliberating an ethics issue and resolving a conflict but may still provide valuable assistance, as in the case presented.
