Protocol for a Hybrid Implementation-effectiveness Feasibility Study of a Transdisciplinary ICU-to-home Recovery Model (THRIVE@TTSH)

30. september 2026 oppdatert av: Lau Yie Hui, Tan Tock Seng Hospital

Transition Support and Holistic Recovery Interventions for Vulnerable Ex-ICU Patients @ Tan Tock Seng Hospital (THRIVE@TTSH): Protocol for a Hybrid Implementation-effectiveness Feasibility Study of a Transdisciplinary ICU-to-home Recovery Model

This is a prospective, single-centre study which will recruit 50 adult ICU survivors over 12 months. Assessments will occur during hospitalisation and at Months 3 and 6 after hospital discharge, with a final phone follow-up at Month 12. There will be volunteer-supported home visits for 6 months post hospital discharge.

Detaljert beskrivelse

This is a prospective, single-centre hybrid implementation-effectiveness feasibility study which will recruit 50 adult ICU survivors over 12 months. Assessments will occur during hospitalisation and at Months 3 and 6 after hospital discharge, with a final phone follow-up at Month 12. There will be volunteer-supported home visits for 6 months post hospital discharge. The primary feasibility outcome is the proportion of enrolled participants alive at Month 6 who complete outcome assessment.

Secondary implementation outcomes include recruitment, retention, home-visit completion and acceptability. Exploratory outcomes include Post ICU Syndrome (PICS) recovery trajectories, healthcare utilisation and mortality through 12 months post discharge from the acute hospital.

Beskrivelse

Inclusion criteria

  1. Received invasive mechanical ventilation for ≥ 48 hours;
  2. Aged ≥ 21 years;
  3. Premorbidly independent in basic activities of daily living;
  4. Had decision-making capacity before the acute illness and are expected to regain capacity before acute hospital discharge;
  5. Have evidence of new or worsening physical, cognitive, mental-health or swallowing impairment compared with their premorbid state; and
  6. Are ultimately planned for discharge to the community/home setting. Worsening in PICS domains is defined as an increase in CFS score compared with premorbid status, newly acquired swallowing dysfunction, new cognitive impairment after exclusion of delirium, suspected anxiety or depressive symptoms, or clinically important deterioration in physical or functional performance.

Mental-health screening will not be interpreted as diagnostic criteria for anxiety or depressive disorders.

Exclusion criteria

  • cognitive or psychiatric impairment that precludes meaningful participation in the study;
  • are already enrolled in, or expected to enter, a structured follow-up pathway that substantially duplicates the rehabilitation intervention; or
  • have treatment primarily directed towards palliation or end-of-life care
