OBJECTIVES: To determine optimal repositioning
frequency of nursing home (NH) residents at risk for pressure ulcers (PrUs) when cared for on high-density foam mattresses.
DESIGN: Multisite, randomized, clinical trial, known as
Turning for Ulcer ReductioN (TURN Study).
SETTINGS: NHs in the United States (n = 20) and
Canada (n = 7) using high-density foam mattresses.
PARTICIPANTS: Consenting residents (N = 942) aged 65
and older without PrUs at moderate (scores 13–14) or high
(scores 10–12) risk of PrUs according to the Braden Scale. INTERVENTION: Participants were randomly allocated
using risk stratification (moderate vs high) to a repositioning schedule (2, 3, or 4 hour) for 3 weeks. Blinded assessors assessed skin weekly.
MEASUREMENTS: PrU incidence (coccyx or sacrum,
trochanter, heels).
RESULTS: Participants were mostly female (77.6%) and
Caucasian (80.5%) and had a mean age of 85.1 Æ 7.7.
The most common diagnoses were cardiovascular (76.9%)
and dementia (72.5%). Nineteen (2.0%) participants
developed superficial PrUs. There was no significant
difference (Wilcoxon test for ordered categories) in PrU
incidence (P = .68) according to repositioning group
(2 hour, 8/321, 2.5%; 3 hour, 2/326, 0.6%; 4 hour, 9/
295, 3.1%), nor was there a statistically significant
difference in the incidence of PrU between the high and
moderate-risk groups (P = .79). Also, PrU incidence was
not statistically significantly different between high-risk participants based on repositioning schedule (6/325, 1.8%,
P = .90) or between moderate-risk participants based on
repositioning schedule (13/617, 2.1%, P = .68).

CONCLUSION: There was no difference in PrU incidence
over 3 weeks of observation between those turned at
2-, 3-, or 4-hour intervals in this population of residents
using high-density foam mattresses at moderate and high
risk of developing PrUs when they were repositioned
consistently and skin was monitored. This finding has
major implications for use of nursing staff and cost of NH
care. J Am Geriatr Soc 61:1705–1713, 2013.

P

ressure ulcers (PrUs) are a common problem in nursing
home (NH) residents; the prevalence of PrUs in residents at high risk of developing PrUs at the outset of the study was 11.6% according to Nursing Home Compare;1
other studies have reported a 14% to 24% PrU incidence
on standard mattresses or foam overlays.2,3 Economic
evaluation of the cost of prevention is emerging and
variable, with support surfaces and repositioning identified as more costly elements of prevention.4–6 Pressure at the
interface between bony prominences and support surfaces
sufficient to occlude or reduce blood flow to tissues is
thought to cause PrUs.7,8 Redistributing (through properties of support surfaces) and relieving (through repositioning) pressure to reduce length of exposure to pressure prevents PrUs. High-density foam mattresses distribute

pressure more evenly and are replacing...
