Analyzing the prognosis of older patients after invasive mechanical ventilation based on health and long-term care insurance data from Tsukuba City

Tsukuba, Japan—Prognostic information is crucial when considering the use of mechanical ventilation. However, there have been few reports detailing the proportion of older patients who are able to be weaned from mechanical ventilation or discharged from the hospital. In this study, researchers examined health and long-term care insurance data from Tsukuba City (April 2014 to March 2019) to investigate the proportion of older patients (aged 65 years or above) who underwent tracheal intubation and mechanical ventilation and were subsequently weaned from the ventilator and discharged from the hospital.

The study included 272 patients, excluding those who underwent ventilation for surgical purposes and those who died within three days of ventilation. Of these, 73.5% were weaned off the ventilator within 180 days, and 42.6% were discharged from the hospital within the same period. In contrast, 37.5% of the patients died within 180 days, and 19.9% remained hospitalized beyond 180 days. When dividing patients by age and care level, no significant differences were observed in the duration of mechanical ventilation or hospitalization across age groups. However, patients with a care level of 3 or higher at admission had a higher proportion of prolonged hospitalization beyond 180 days compared to those with lower care levels.

Although many older patients who survived more than three days after receiving mechanical ventilation via endotracheal intubation were able to be extubated, hospitalization tended to be prolonged in those with a high care level. These findings highlight the need to consider the potential disadvantages of long-term hospitalization. In counseling sessions involving patients, their families, and physicians regarding treatment plans, it may be important to address not only the potential difficulty of ventilator liberation but also the risk of undesired outcomes and physical function decline.
