Up to 30% of patients with Guillain–Barré syndrome require mechanical ventilation and 5% die due to acute complications of mechanical ventilation. There is a considerable group of patients that will need prolonged mechanical ventilation (considered as >14 days) and should be considered for early tracheostomy. The objective of this study is to identify risk factors for prolonged mechanical ventilation.

We prospectively analyzed patients with Guillain–Barré diagnosis with versus without prolonged mechanical ventilation. We considered clinical and electrophysiological characteristics and analyzed factors associated with prolonged mechanical ventilation.

Three hundred and three patients were included; 29% required mechanical ventilation. When comparing the groups, patients with prolonged invasive mechanical ventilation (IMV) have a lower score on the Medical Research Council score (19.5 ± 16.2 vs 27.4 ± 17.5, p = 0.03) and a higher frequency of dysautonomia (42.3% vs 19.4%, p = 0.037), as well as lower amplitudes of the distal compound muscle action potential (CMAP) of the median nerve [0.37 (RIQ 0.07–2.25) vs. 3.9 (RIQ1.2–6.4), p = <0.001] and ulnar nerve [0.37 (RIQ0.0–3.72) vs 1.5 (RIQ0.3–6.6), p = <0.001], and higher frequency of severe axonal damage in these nerves (distal CMAP ≤ 1.0 mV). Through binary logistic regression, severe axonal degeneration of the median nerve is an independent risk factor for prolonged IMV OR 4.9 (95%CI 1.1–21.5) p = 0.03, AUC of 0.774, (95%CI 0.66–0.88), p = < 0.001.

Severe median nerve damage is an independent risk factor for prolonged mechanical ventilation.

The number of patients treated with prolonged mechanical ventilation (PMV) is steadily rising. Traditionally treated within specialized long-term care facilities (LTCFs), healthcare providers are increasingly promoting homecare as a technologically safe, humane, and cheaper alternative. Little is known concerning their informal caregivers (ICGs), despite their crucial role in facilitating care. This study examines caregiver strain among the primary ICG of PMV patients treated at home vs. LTCF.

This study was an observational cross-sectional study. The study enrolled 120/123 PMV patients ≥18 years within the study region (46 treated with homecare/74 treated at the LTCF) and 106 ICGs (34 ICGs/46 homecare patients and 72 ICGs/74 LTCF patients). Caregiver assessment included the 13-item Modified Caregiver Strain Index (Mod CSI) (0–26 maximum); patient assessment included symptom burden (the revised Edmonton Symptom Assessment System).

The mean age of ICGs was 58.9 years old; 60.4% were females; 82.1% were married; 29.2% were patient's spouses; and 40.6% were patient's children. The total Mod CSI was 13.58 (SD 6.52) and similar between home vs. LTCF (14.30 SD 7.50 vs. 13.26 SD 6.03, p = 0.50), or communicative vs. non-communicative patients (13.50 SD 7.12 vs. 13.64 SD 6.04, p = 0.93). Hierarchical analysis identified three clusters of caregiver strain, with ICGs at home vs. LTCF reporting significantly lower mood strain, higher burden, and similar levels of lifestyle disturbance. In adjusted models, homecare was significantly associated with reduced mood strain and increased burden, while increased patient symptomatology was significantly associated with total strain, mood, and burden strain clusters.

Recognizing the different patterns of caregiver strain at home or LTCF is a prerequisite for addressing their palliative care needs and improving the wellbeing and resilience of informal caregivers, who often play a critical role in deciding whether to treat the PMV patient at home or LTCF.
