Characteristics of Nursing Home Resident Movement Patterns: Results from the TEAM-UP Trial.

This is a secondary analysis of trial sensor data, not a new randomised comparison of repositioning schedules. No new pressure injuries developed during the trial, so movement patterns could not be linked to pressure injury development. Only 913 of 1,100 intervention residents were analysed because days with less than 22 hours of sensor data were omitted. Observation time varied from 1 to 28 days, with a mean of 16 days per resident. K-means clustering did not automatically select the number of clusters; the choice of three clusters was made by the investigators. Daily totals may miss time-of-day movement differences, such as evening changes in residents with dementia. Nursing home location and Braden risk were associated with cluster membership, so movement patterns may reflect site or risk differences as well as resident characteristics.

The authors disclosed no other financial relationships related to the article. The underlying TEAM-UP trial is identified as 1R01NR016001.

Do not read the three movement clusters as proof that a particular repositioning schedule prevents pressure injuries. This was a descriptive secondary analysis of sensor data, and it did not compare pressure injury outcomes between repositioning intervals.
