Summary

Therapeutic activity in intensive care units (ICUs) is important but poorly understood. This study found turning was the only consistent activity, with acceptable agreement between observation and actigraphy for measuring its frequency and duration.

Area of Science:

  • Critical Care Medicine
  • Rehabilitation Therapy
  • Clinical Measurement

Background:

  • Therapeutic activity is recognized for its role in preventing functional decline and reducing mortality in intensive care unit (ICU) patients.
  • However, typical levels and types of therapeutic activity in ICUs, particularly for chronically critically ill adults, remain largely uncharacterized.
  • Accurate measurement of patient activity is crucial for research and clinical practice.

Purpose of the Study:

  • To describe typical therapeutic activity in a small sample of chronically critically ill adults.
  • To compare the effectiveness of direct observation and actigraphy in measuring the type, frequency, and duration of therapeutic activity.
  • To assess the agreement between these two measurement methods.

Main Methods:

Related Experiment Videos

  • A preliminary study involving a small sample of chronically critically ill adults.
  • Simultaneous measurement of therapeutic activity using direct observation and actigraphy.
  • Data collected included type, frequency, and duration of activity.

Main Results:

  • Turning was the only consistently documented therapeutic activity, occurring with a frequency of 3 turns per 8 hours and a mean duration of 11 minutes.
  • Acceptable agreement was found between direct observation and actigraphy for measuring the frequency and duration of therapeutic activity.
  • Agreement was not demonstrated for the 'type' of activity between the two methods, although congruence for duration was supported.

Conclusions:

  • Turning represents a primary component of therapeutic activity in this patient population.
  • Direct observation and actigraphy are viable tools for measuring the frequency and duration of therapeutic activity in selected critically ill adults.
  • Findings provide foundational data for future research and clinical implementation of therapeutic activity interventions.
