Initiating non-invasive ventilation in patients with Amyotrophic Lateral Sclerosis in The Netherlands: A centralised approach to respiratory care

Year: 2025

Type: article

Abstract: BACKGROUND: In the Netherlands a centralised approach to respiratory care for patients with Amyotrophic Lateral Sclerosis is used based on national guidelines. Patients with Amyotrophic Lateral Sclerosis are referred to one of 4 centres for Home Mechanical Ventilation. OBJECTIVE: Our aim was to evaluate the respiratory care according to the Dutch guideline by evaluation of reasons for starting non-invasive ventilation, timing of initiating and survival in patients with Amyotrophic Lateral Sclerosis using non-invasive ventilation. METHOD: A retrospective chart-review was performed of 323 patients, who had been referred to centres for Home Mechanical Ventilation in 2016-2018. Data collected included symptoms of hypoventilation, forced vital capacity, blood gasses, criteria for (not) initiating non-invasive ventilation, and survival. Kaplan-Meyer curves and Multivariate Cox proportional hazard regression were used in the analysis. RESULTS: The main criteria used for initiating non-invasive ventilation were hypercapnia (77%) and the presence of orthopnea and/or dyspnoea (25%). Median survival after starting non-invasive ventilation was 11 months, and was shorter for patients with bulbar disease onset and older age. The proportion of the total disease duration that was spent on non-invasive ventilation was not significantly affected by age, sex or site of disease. Seventy nine percent of the patients who didn't start non-invasive ventilation had reached a joint decision with their caregivers and/or physicians. CONCLUSION: Key outcomes of the Dutch centralised respiratory care approach have shown that most patients were initiated on non-invasive ventilation due to presence of hypercapnia and/or dyspnoea/orthopnea, which is according to the Dutch guidelines. Half of patients spent at least 33% of their disease duration on non-invasive ventilation. To help find the optimal criteria and timing for non-invasive ventilation it would be useful for other countries to share their key outcomes as well.
