Prolonged Mechanical Ventilation (PMV): When is it Justified in ICU?

Area of Science:

• Critical Care Medicine
• Respiratory Medicine
• Health Services Research

Background:

• The number of patients requiring prolonged mechanical ventilation (PMV) in intensive care units (ICUs) is increasing.
• PMV is defined as requiring invasive mechanical ventilation for 21 consecutive days (at least 6 hours/day).
• Improved ICU care leads to more survivors of acute respiratory failure, likely increasing PMV incidence.

Discussion:

• PMV patients consume a disproportionate amount of healthcare resources.
• These patients incur high illness costs and utilize significant ICU bed days.
• PMV patients experience longer hospital stays post-ICU discharge compared to non-PMV patients.

Key Insights:

• Incidence of PMV in a UK multi-centric study was 4.4 per 100 ICU admissions.
• PMV patients accounted for 29.1% of all general ICU bed days.
• Hospital mortality was higher in PMV patients (40.3%) versus non-PMV patients (33.8%, P = 0.02).

Outlook:

• The trend of increasing PMV numbers necessitates attention from health service planners.
• Understanding PMV resource utilization is crucial for healthcare management.
• Further research into optimizing care and reducing mortality for PMV patients is warranted.
