The Role of Noninvasive Ventilation in Patients with "Do Not Intubate" Order in the Emergency Setting

Noninvasive ventilation (NIV) is being used increasingly in patients who have a "do not intubate" (DNI) order. However, the impact of NIV on the clinical and health-related quality of life (HRQOL) in the emergency setting is not known, nor is its effectiveness for relieving symptoms in end-of-life care. OBJECTIVE: The aim of this prospective study was to determine the outcome and HRQOL impact of regular use of NIV outcomes on patients with a DNI order who were admitted to the emergency room department (ED). METHODS: Eligible for participation were DNI-status patients who receive NIV for acute or acute-on-chronic respiratory failure when admitted to the ED of a tertiary care, university-affiliated, 600-bed hospital between January 2014 and December 2014. Patients were divided into 2 groups: (1) those whose DNI order related to a decision to withhold therapy and (2) those for whom any treatment, including NIV, was provided for symptom relief only. HRQOL was evaluated only in group 1, using the 12-item Short Form Health Survey (SF-12). Long-term outcome was evaluated 90 days after hospital discharge by means of a telephone interview. RESULTS: During the study period 1727 patients were admitted to the ED, 243 were submitted to NIV and 70 (29%) were included in the study. Twenty-nine (41%) of the 70 enrollees received NIV for symptom relief only (group2). Active cancer [7% vs 35%, p = 0,004] and neuromuscular diseases [0% vs. 17%] were more prevalent in this group. NIV was stopped in 59% of the patients in group 2 due to lake of clinical benefit. The in-hospital mortality rate was 37% for group 1 and 86% for group 2 0,001). Among patients who were discharged from hospital, 23% of the group 1 and all patients in group 2 died within 90 days. Relative to baseline, no significant decline in HRQOL occurred in group 1 by 90 days postdischarge. CONCLUSION: The survival rate was 49% among DNI-status patients for whom NIV was used as a treatment in ED, and these patients did not experience a decline in HRQOL throughout the study. NIV did not provide significant relief of symptoms in more than half the patients who receive it for that purpose.Supported, in part, by grants from the Discipline of Initiation to Clinical Investigation (Disciplina de Iniciação à Investigação Clínica) of Instituto de Ciências Biomédicas Abel Salazar and in part by ASSUCIP (Associação dos Amigos da Unidade de Cuidados Intensivos Polivalente, Hospital de Santo António, Porto, Portugal).info:eu-repo/semantics/publishedVersio
