PURPOSE: The purpose of this study was to examine the effect of noncontact
low-frequency ultrasound (NLFU) on deep tissue pressure injury (DTPI), both
hospital-acquired and those present on admission (POA).
DESIGN: Retrospective, descriptive study.
SAMPLE AND SETTING: Medical records from 44 adult patients with a DTPI treated
with NLFU were reviewed; 22 had a hospital-acquired DTPI (HADTPI) and 22 had DTPI
POA. Their mean age was 71.3 ± 16.3 years (mean ± SD); 52% were male. The study
setting was a 318-bed community hospital in the Mid-Atlantic region of the United
States.
METHODS: Data were collected from the medical records including demographic and
relevant clinical characteristics, DTPI measurements, and DTPI
evolution/resolution. Data were summarized and examined using descriptive
statistics (eg, frequencies and percentages and means and standard deviations).
Differences between groups were examined using paired t tests or the Mann-Whitney
U test and the chi-square test as appropriate. In addition, the heel DTPI
subgroup (N = 8) was examined separately due to the small sample size.
RESULTS: All patients with HADTPI and DTPI POA treated with NLFU exhibited a
statistically significant decrease in injury size from initiation to
discontinuation of NLFU therapy (24.6 cm vs 14.4 cm, P = .02). No statistically
significant difference in wound resolution was found between HADTPI versus DTPI
POA (27% vs 18%, P = .47). Mean size of both HADTPI and DTPI POA decreased
significantly from 15.9 to 13.4 cm (P = .045) by NLFU therapy. Wounds were
classified as resolved at completion of treatment in 23% (10 out of 44) of all
treated patients. Of all patients with the potential to be resolved (not
discharged early or expired) 63% (10 out of 16) had wounds classified as
resolved.
CONCLUSION: Study findings suggest that NLFU is a viable and promising treatment
option for both HADTPI and DTPI POA. Future studies are needed to confirm these
results and to examine efficacy and feasibility of DTPI across care settings.
