A warming climate poses substantial risk to public health and worsens existing health inequity. As a contributor to greenhouse gas emissions and air pollution, the health sector has obligations and ample opportunities to protect health by decreasing waste and motivating more system-wide sustainable clinical practices. Such efforts will have important ethical implications for health equity. [ABSTRACT FROM AUTHOR]

Background: Nearly one-quarter of all Americans die in the ICU. Many of their deaths are anticipated and occur following the withdrawal of mechanical ventilation (WMV). However, there are few data on which to base best practices for interdisciplinary ICU teams to conduct WMV., Research Question: What are the perceptions of current WMV practices among ICU clinicians, and what are their opinions of processes that might improve the practice of WMV at end of life in the ICU?, Study Design and Methods: This prospective two-center observational study conducted in Boston, Massachusetts, the Observational Study of the Withdrawal of Mechanical Ventilation (OBSERVE-WMV) was designed to better understand the perspectives of clinicians and experience of patients undergoing WMV. This report focuses on analyses of qualitative data obtained from in-person surveys administered to the ICU clinicians (nurses, respiratory therapists, and physicians) caring for these patients. Surveys assessed a broad range of clinician perspectives on planning, as well as the key processes required for WMV. This analysis used independent open, inductive coding of responses to open-ended questions. Initial codes were reconciled iteratively and then organized and interpreted using a thematic analysis approach. Opinions were assessed on how WMV could be improved for individual patients and the ICU as a whole., Results: Among 456 eligible clinicians, 312 in-person surveys were completed by clinicians caring for 152 patients who underwent WMV. Qualitative analyses identified two main themes characterizing high-quality WMV processes: (1) good communication (eg, mutual understanding of family preferences) between the ICU team and family; and (2) medical management (eg, planning, availability of ICU team) that minimizes patient distress. Team member support was identified as an essential process component in both themes., Interpretation: Clinician perceptions of the appropriateness or success of WMV prioritize the quality of team and family communication and patient symptom management. Both are modifiable targets of interventions aimed at optimizing overall WMV.
