Study summary

This is a prospective, observational study at the ICU of Hospital Mútua de Terrassa, running from May to December 2025. The primary goal is to determine the prevalence of sarcopenia in adult patients requiring more than 48 hours of mechanical ventilation. Sarcopenia is assessed using the SARC-F score, impedanciometry, and quadriceps ultrasound. Secondary aims include tracking the development of ICU-Acquired Weakness (ICU-AW) using the MRC score. All data is collected anonymously after obtaining informed consent.

What researchers measure

Primary outcomes

  1. Prevalence of sarcopenia at the time of ICU admission.

    Describe the prevalence of sarcopenia at the time of ICU admission in patients with an expected duration of mechanical ventilation (MV) exceeding 48 hours.

    Time frame: Baseline at admission to ICU

Secondary outcomes

  1. Detecting patients who develop ICU-Acquired Weakness (ICU-AW) and/or prolonged mechanical ventilation weaning

    Detecting patients who develop ICU-Acquired Weakness (ICU-AW) and/or prolonged mechanical ventilation weaning, defined as failure of definitive disconnection from mechanical ventilation

    Time frame: From ICU admission to 30 days follow-up

  2. Detecting the appearance of other complications

    Detecting the appearance of other complications during admission such as: the appearance of refeeding syndrome or increased prevalence of insulin resistance.

    Time frame: From admission to 30 days follow up

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Started May 2025 (actual). Primary completion is estimated for Dec 2025, 7 months after the start.

Of 192 non-industry observational studies under Sarcopenia, half reached primary completion within 26 months of starting (the median), counting those still running; a quarter within 12 and three quarters within 63. This study's planned 7 months is below that.

Counting every sponsor, half of 194 studies reached it within 26 months; a quarter within 12 and three quarters within 63.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Dec 24, 2025, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
