title: Pressure Ulcer Prevention Study

description: Medically serious pressure ulcers
(MSPrUs), a common complication of spinal cord injury (SCI), have devastating consequences
on health and well-being and are extremely expensive to treat.  The study objective was to test the efficacy
of a lifestyle-based intervention designed to reduce the incidence of MSPrUs in
an at-risk population of adults with SCI.

 

We conducted a single-site,
single-blind, randomized controlled trial (RCT), and a separate study wing
involving a nonrandomized standard care control group.  Recruitment and ongoing medical treatment were
undertaken at Rancho Los Amigos National Rehabilitation Center, a large
facility serving ethnically diverse, low income residents of Los Angeles
County.  Adults with SCI who had one or
more prior MSPrUs over the past 2 years were enrolled and evaluated: N=82 in
randomized intervention (RI), N=84 in randomized control (RC), N=66 in
nonrandomized no-contact control (NCC).

 

The Pressure Ulcer Prevention Program
was a 12-month lifestyle-based treatment administered by healthcare
professionals, largely via in-home visits and phone contacts.

 

In the RI and RC groups, study
nurses, blind to the participants’ condition assignments, conducted skin checks
at baseline, 12 months and 24 months.  In
addition, trained interviewers (also blind to condition assignments) administered
an assessment battery including questionnaires to measure health-related
quality of life (Adapted RAND 36-Item Health Survey 1.0 (SF-36)), life
satisfaction (Satisfaction with Life Scale (SWLS)), depression (Quasi-Adaptive
Short Form for the Patient Reported Outcomes Measurement Information System
(PROMIS) Version 1 Depression Item Bank), social support (Interpersonal Support
Evaluation List (ISEL)), drug and alcohol use (Adapted Cut Down, Annoyed,
Guilty, and Eye Opener (CAGE) Questionnaire), knowledge of ulcer prevention (Pressure
Ulcer Knowledge Test), performance of preventive behaviors (Garber Procedure
for Assessing Performance of Preventive Behaviors), and self-efficacy (Adapted
Moorong Self Efficacy Scale), at study baseline, 12 months and 24 months.  At baseline a set of eligibility and background
variables were also measured.  The NCC
group received an abbreviated assessment including eligibility, background and
social support, drug and alcohol use, and depression questionnaires, and were
not followed beyond 12 months.

The primary outcome for the study was
the annualized MSPrU incidence rates at 12 and 24 months, based on: skin
checks, quarterly phone interviews with participants, and review of medical
charts and billing records. MSPrUs were classified as either serious (stages 3
and 4, unstageable and suspected deep tissue injury) or non-serious (stages 1
and 2).  Secondary outcomes included
number of surgeries and various quality-of-life measures assessed by the
questionnaires.

description: Adults with spinal cord injury and a history of medically serious pressure injury<br>Smallest Geographic Unit: N/A
description: Prospective participants for this study were adults (≥ 18 years of age) with SCI (paraplegia or tetraplegia) who had a history of at least one stage 3 or stage 4 PrI in the past five years, were currently utilizing RLANRC services, and had an existing medical chart at the facility. Additional inclusion criteria were: (1) English- or Spanish-speaking; (2) contactable by telephone or cell phone; (3) cognitively intact (based on unadjusted score ≥ 7 on the Short Portable Mental Status Questionnaire [SPMSQ]); (4) willing to undertake recommended lifestyle changes for MSPrI prevention; and (5) residing within 100 miles of RLANRC. Participants were excluded if they: (1) were ambulatory; (2) were less than 6 months post-injury; (3) had an unstable or worsening stage 3, or any stage 4, PrI present; or (4) participated in any of our prior research studies.<br><br><br>
