    Intensive Palliative Care: Improving the Process of Palliative Ventilator Withdrawal Among Critically Ill Older Adults
    Role Description: More than 1 in 5 Americans die in intensive care units (ICUs). This study will generate information to reduce distress among older ICU patients on mechanical ventilation who are transitioning to comfort focused care, and then develop and test an ICU team-based intervention to improve symptom control.
    Role: Principal Investigator

PMC Citations indicate the number of times the publication was cited by articles in PubMed Central, and the Altmetric score represents citations in news articles and social media. (Note that publications are often cited in additional ways that are not shown here.) Fields are based on how the National Library of Medicine (NLM) classifies the publication's journal and might not represent the specific topic of the publication. Translation tags are based on the publication type and the MeSH terms NLM assigns to the publication. Some publications (especially newer ones and publications not in PubMed) might not yet be assigned Field or Translation tags.) Click a Field or Translation tag to filter the publications.
