Outcome after tracheostomy for respiratory failure in the elderly

Area of Science:

• Geriatric Medicine
• Pulmonology
• Critical Care

Background:

• Tracheostomy is a common procedure for patients with respiratory failure requiring mechanical ventilation.
• Outcomes in elderly patients undergoing tracheostomy, particularly comparing different age strata, require further investigation.

Purpose of the Study:

• To evaluate hospital and postdischarge survival and functional status in elderly patients (≥65 years) following tracheostomy for respiratory failure.
• To compare outcomes between younger elderly (65-74 years) and older elderly (≥75 years) populations.

Main Methods:

• Retrospective chart review of 228 patients aged 65 years or older who underwent tracheostomy for mechanical ventilation.
• Prospective administration of the SF-36 questionnaire to assess functional status in a subset of patients.
• Analysis of demographics, comorbidities, survival rates, ventilator liberation, and functional status.

Main Results:

• No significant difference in combined hospital and hospice mortality between younger (34%) and older (26%) elderly groups.
• Older patients (≥75 years) were significantly more likely to be discharged requiring mechanical ventilation (62% vs. 45%).
• Approximately 50% of hospital survivors died within one year; ventilator-dependent survivors had higher mortality.
• SF-36 results indicated fair to good emotional/social functioning but severe physical limitations in participants.

Conclusions:

• While overall mortality is similar, older elderly patients face a higher likelihood of prolonged mechanical ventilation dependency post-tracheostomy.
• Functional status in survivors is significantly impacted, particularly physical limitations, irrespective of age group.
• Ventilator dependency is a critical factor influencing long-term survival post-tracheostomy in the elderly.
