Absence of airway secretion accumulation predicts tolerance of noninvasive ventilation in subjects with amyotrophic lateral sclerosis.

OBJECTIVE: To assess factors that predict good tolerance of noninvasive ventilation (NIV), in order to improve survival and quality of life in subjects with amyotrophic lateral sclerosis. METHODS: We conducted a prospective study in subjects with amyotrophic lateral sclerosis and requiring NIV. The primary end point was NIV tolerance at 1 month. Subjects, several of whom failed to complete the study, were classified as "tolerant" or "poorly tolerant," according to the number of hours of NIV use (more or less than 4 h per night, respectively). RESULTS: Eighty-one subjects, 73 of whom also attended the 1-month follow-up visit, participated over 34 months. NIV tolerance after the first day of utilization predicted tolerance at 1 month (77.6% and 75.3% of subjects, respectively). Multivariate analysis disclosed 3 factors predicting good NIV tolerance: absence of airway secretions accumulation prior to NIV onset (odds ratio 11.5); normal bulbar function at initiation of NIV (odds ratio 8.5); and older age (weakly significant, odds ratio 1.1). CONCLUSION: Our study reveals 3 factors that are predictive of good NIV tolerance, in particular the absence of airway secretion accumulation, which should prompt NIV initiation before its appearance.

Circumstances of death in hospitalized patients and nurses' perceptions: French multicenter Mort-a-l'Hôpital survey.

BACKGROUND: In developed countries at present, death mostly occurs in hospitals, but the circumstances and factors associated with the quality of organization and care surrounding death are not well described. METHODS: We designed a large multicenter cross-sectional study to analyze the setting and clinical course of each patient on the day of death. We included 2750 clinical departments of 294 hospitals. Of these, 1033 departments (37.6%) of 200 hospitals (68.0%) contributed to the Mort-a-l'Hôpital survey. Data were collected prospectively by the bedside nurse of each patient within 10 days of the occurrence of death. Main outcome measures included circumstances of death in hospitalized patients; secondary outcomes, nurses' perceptions of quality of end-of-life care. RESULTS: Of the 1033 participating departments, 420 recorded no deaths during the study period and 613 declared at least 1 death. In the 3793 patients who died and were included for assessment, only 925 (24.4%) had loved ones present at the time of death; 70.1% had respiratory distress during the period before death; and only 12.0% were in pain. Written protocols for end-of-life care were available in 12.2% of participating departments. Only 35.1% of nurses judged the quality of dying and death acceptable for themselves. Principal factors significantly associated with this perception were availability of a written protocol for end-of-life care, anticipation of death, informing the family, surrogate designation, adequate control of pain, presence of family or friends at the time of death, and staff meeting with the family after the death. CONCLUSIONS: This large prospective study identifies nonoptimal circumstances of death for hospitalized patients and a number of suggestions for improvement. A combination of factors reflected in the nurses' satisfaction may improve the quality of end-of-life care.
