Association between Palliative Care Consultation and Advance Palliative Care Rates: A Descriptive Cohort Study in Patients at Various Stages in the Continuum of Chronic Kidney Disease.

Background: Despite evidence that advance care planning (ACP) benefits patients with serious illnesses, there is a dearth of information about "who" is referred for palliative care (PC) consultation, the rate of PC consultation, and the outcomes of referrals in patients with advanced chronic kidney disease/end-stage kidney disease (aCKD/ESKD). Objectives: (1) To describe patient characteristics associated with PC consultations and (2) to determine the frequency and outcome of PC consultation on documented ACP discussions for patients with aCKD/ESKD. Methodology/Design: This is retrospective observational electronic health record cohort review. Settings: University of Virginia (UVA) hospital, clinics, and dialysis units. Participants: Patients were studied along two time intervals. Time period January 1, 2015 to June 30, 2017 included all patients admitted to UVA during that time period with estimated glomerular filtration rate (eGFR) <60 mL/minute. Time period January 1, 2018 to March 31, 2019 included two cohorts: patients with eGFR <15 mL/minute who had died during study period excluding those who withdrew from dialysis and those who were dialysis dependent and withdrew from dialysis. Results: Aside from higher rates of PC consultation in patients with heart failure, none of the demographic and comorbidity data studied affected whether or not a patient is referred to PC in patients with aCKD/ESKD. PC consultation rates were low among all patients studied: 14.7% in patients with eGFR <60 mL/minute, 28.9% in dialysis patients withdrawing from dialysis, and 57.1% in terminally ill patients with eGFR <15 mL/minute. In all cohorts, PC consultations were associated with improved ACP. Conclusion: PC consultation is significantly associated with better end-of-life outcomes with more completion of ACP and hospice referral in patients with aCKD/ESKD. PC consultation rates remain low. Even in terminally ill patients with more aCKD, >40% were never seen by PC. Until policies and curricula better prepare nephrologists to independently address ACP, collaboration between nephrologists and PC specialists is recommended.

Cardiac Arrest as a Consequence of Air Embolism: A Case Report and Literature Review.

Air embolism is an infrequent but potentially catastrophic complication. It could be a complication of invasive procedures including surgery, central line placement, positive pressure ventilation, trauma, hemodialysis, pacemaker placement, cardiac ablation, and decompression sickness. Usually, it does not cause any hemodynamic complication. In rare cases, it could lodge in the heart and cause cardiac arrest. We present a case of an 82-year-old white female who underwent computed tomography (CT) guided biopsy of right lung pulmonary nodule. When she was turned over after the lung biopsy, she became unresponsive and developed cardiopulmonary arrest. She underwent successful resuscitation and ultimately was intubated. CT chest was performed immediately after resuscitation which showed frothy air dense material in the left atrium and one of the right pulmonary veins suggesting a Broncho venous fistula with air embolism. Although very rare, air embolism could be catastrophic resulting in cardiac arrest. Supportive care including mechanical ventilation, vasopressors, volume resuscitation, and supplemental oxygen is the initial management. Patients with cardiac, neurological, or respiratory complications benefit from hyperbaric oxygen therapy.
