Aim: To assess the effectiveness of thermography, colorimetry, and oximetry at detecting temperature changes after erythema induction across diverse skin tones in healthy adults., Materials and Methods: Erythema was induced at the forearm and ulnar head (UH) using a cupping device. Temperature via thermal image, erythema value via colorimeter, and oxygen saturation via oximeter were collected immediately and 5-10 min (delayed) after cupping at both sites., Results: At the forearm, the delayed timepoint was significantly warmer than baseline. At the UH, the immediate timepoint was significantly colder than baseline. Erythema increased at both timepoints and both locations. The correlation between temperature change and erythema change was weak. Change in temperature did not differ between skin tone groups. The Intermediate Low Eumelanin skin tone group had more change in erythema compared to the Intermediate Mid (i.e., darkest) skin tone group immediately after cupping at the UH and at the delayed timepoint at the forearm., Conclusions: This study observed differences in the change of erythema across skin tones but did not observe differences in temperature across skin tones. Given high variability in results, it is premature to conclude thermal imaging works equally well across all skin tones. Further research is necessary to validate the effectiveness of thermal imaging in diverse populations. Results suggest visual erythema may be a problematic indicator as less erythema was consistently noted in participants with dark skin tones. The potential of technology to increase our ability to detect erythema warrants further investigation., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 Tissue Viability Society / Society of Tissue Viability.

Objective: Examine pressure injury (PrI) pain severity, stability, and current treatment of PrI pain among nursing home (NH) residents using two assessment tools and a descriptive cohort study design., Background: PrI pain affects quality of life of NH residents yet, best assessment methods, stability of PrI pain, and how to take care of the pain are not well known., Methods: Data collected from 33 residents with PrI (stages 1-4) from 4 NHs. All PrI were staged and assessed using the Bates-Jensen Wound Assessment Tool (BWAT) to determine severity. Verbal Response Scale (VRS) and Pain Assessment in Advanced Dementia (PAINAD) were used to assess general and PrI pain 3 times a day for two days within one week. Data classified as: no, mild, moderate, or severe pain. Proportions of participants with different levels of PrI pain were calculated. T tests were conducted to examine differences across time; VRS and PAINAD were examined for agreement., Results: Participants were 74 % female, 49 % white, 58 % cognitively intact, 58 % functionally dependent, and had mean age of 82 years old. The majority (52 %; n = 17) were full thickness PrI, stage 3 (n = 5), stage 4 (n = 7), unstageable (n = 5). The majority of participants (82 %; n = 27) reported PrI pain on at least one of six assessments over the two days; with 57 % mild, 26 % moderate and 16 % severe pain. More severe pain occurred in afternoon. No differences existed across days. Although there was a positive relationship between VRS and PAINAD in pain assessments (r = 0.38, P<.05), the agreement between the two scales, as indicated by Cohen's kappa (K = 0.19, p=.28), was found to be poor. Of those with PrI pain, 22 % had pain documented in the Minimum Data Set (MDS). Only 42 % of participants who reported PrI pain received pain medication within 12 h of initial pain assessment. Out of 28 participants who received routine pain medication for general pain, 18 of them reported experiencing no pain., Conclusion: While VRS and PAINAD scores exhibited a relationship, their agreement was limited. Documentation of PrI pain on the Minimum Data Set (MDS) was found to be inadequate. Notably, 40 % of participants reported higher levels of PrI pain in the afternoon, suggesting this time may be opportune for PrI pain assessment and management. Interestingly, participants who received medication for general pain did not report PrI pain, suggesting that treatment of general pain may effectively alleviate PrI pain symptoms., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Published by Elsevier Inc.)

Objective: To determine if subepidermal moisture (SEM) measures help detect and prevent intraoperative acquired pressure injuries (IAPIs) for prone-position surgery., Methods: In this clinical trial of patients (n = 39 preintervention, n = 48 intervention, 100 historical control) undergoing prone-position surgery, researchers examined the use of multidimensionally flexible silicone foam (MFSF) dressings applied preoperatively to patients' face, chest, and iliac crests. Visual skin assessments and SEM measures were obtained preoperatively, postoperatively, and daily for up to 5 days or until discharge. Electronic health record review included demographic, medical, and surgery data., Results: Of the 187 total participants, 76 (41%) were women. Participants' mean age was 61.0 ± 15.0 years, and 9.6% were Hispanic (n = 18), 9.6% were Asian (n = 18), 6.9% were Black or African American (n = 13), and 73.8% were White (n = 138). Participants had a mean Scott-Triggers IAPI risk score of 1.5 ± 1.1. Among those with no erythema preoperatively, fewer intervention participants exhibited postoperative erythema on their face and chest than did preintervention participants. Further, fewer intervention participants had SEM-defined IAPIs at all locations in comparison with preintervention participants. The MFSF dressings overcame IAPI risk factors of surgery length, skin tone, and body mass index with fewer IAPIs in intervention participants., Conclusions: Patients undergoing prone-position surgeries developed fewer IAPIs, and SEM measures indicated no damage when MFSF dressings were applied to sites preoperatively. The SEM measures detected more damage than visual assessment., (Copyright © 2024 Wolters Kluwer Health, Inc. All rights reserved.)
