Pressure injury pain over time among nursing home residents.

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.

Thermal measurement of erythema across skin tones: Implications for clinical identification of early pressure injury.

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.

Decreasing Intraoperative Skin Damage in Prone-Position Surgeries.

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.

Preventing Community-Acquired Pressure Injuries in Spinal Cord Injury: Online Healthcare Provider Curriculum.

PURPOSE: The aim of this study was to develop and pilot an educational curriculum for healthcare providers to better understand community-acquired pressure injury (CAPrI) prevention in veterans living with spinal cord injury (SCI). METHODS: The Thomas six-step process model guided curricular development and evaluation. Curriculum development followed six steps: (1) problem identification and general needs assessment from a literature review and qualitative research triangulating provider and veteran perspectives of CAPrI prevention in SCI, (2) target needs assessment using a focus group with 14 experienced practicing interprofessional SCI providers, (3) creation of module goals and objectives with content review from experts ( n = 8), (4) development of curriculum content and educational strategies, (5) implementation of a pilot ( n = 4), and (6) evaluation of satisfaction and curriculum content via survey and focus group. RESULTS: A five-module online curriculum was evaluated positively and is available publicly. Modules include (1) CAPrI Prevention Clinical Guidelines for the Provider, (2) CAPrI Prevention from the Veteran Perspective, (3) Building Collaborative Relationships, (4) Accessing Resources, and (5) Team Approach. Pilot participants stated objectives were met; they were satisfied with the module. The participants did recommend some changes. CLINICAL RELEVANCE: Understanding CAPrI prevention can inform rehabilitation nursing care. CONCLUSIONS: An asynchronous educational curriculum can support nurses in integrating preventive care in community-dwelling veterans living with SCI.

Development of a decision support tool to prevent community acquired pressure injuries for use in the spinal cord injury clinic using the delphi technique.

STUDY DESIGN: Delphi Technique. OBJECTIVES: Describe the development of a decision support tool to prevent community-acquired pressure injuries (CAPrIs) in individuals with spinal cord injury (SCI) for use in SCI clinics, called the Community-Acquired Pressure Injury Prevention-Field Implementation Tool (CAPP-FIT). SETTING: Veteran Health Administration Hospital, Chicago, Illinois, USA. METHODS: Concept mapping of current pressure injury (PrI) guidelines and qualitative research describing risks, actions, and resources needed to prevent CAPrIs associated with SCI were used to develop 40 veteran checklist items (Items) along with 37 associated provider actions (Actions) for the tool. The Delphi technique was used to refine Items and Actions with a panel of interprofessional SCI providers (n = 15), veterans with SCI (n = 4), and caregivers (n = 3) to determine consensus on a 4-point Likert scale (strongly agree-strongly disagree) for each Item and Action. A 75% agreement was set for responses rated as strongly agree or agree. RESULTS: Panelists were 60% female, 62% White, 33% veterans with SCI or caregivers, 33% wound care certified with a mean age of 59 years. Two survey rounds were required for consensus for 41 Item and 38 Action CAPP-FIT. Response rate was 95% for both rounds. Delphi round 1 showed all but two Actions affirming agreement above 75%. Substantive comments from panelists required revision to 5 Items and 9 Actions and one additional Item/Actions related to coping, meeting threshold percent agreement in Round 2. CONCLUSIONS: The CAPP-FIT could become a useful tool for Veterans living with SCI, caregivers, and SCI providers.

Using Technology to Detect Erythema Across Skin Tones.

OBJECTIVE: To examine the effectiveness of the ColorMeter DSM III (ColorMeter; Cortex Technology) at grouping individuals by skin tone and measuring erythema/skin discoloration after erythema induction across skin tones. METHODS: This pre/post experimental study induced erythema on a convenience sample of 61 healthy adults. Skin tone at baseline was measured using the ColorMeter, Munsell Soil Color Chart 5YR (Munsell), and Pantone SkinTone Guide (Pantone) and compared with the Eumelanin Human Skin Colour Scale (Eumelanin Scale) groupings. Erythema and melanin values on the arm immediately and after recovery time were compared with baseline values. Melanin was measured at five body regions on the face and arm. RESULTS: Participants were predominantly women (64% [n = 39] women, 36% [n = 22] men) and young (mean, 28.8 ± 14.3 years); 5% (n = 3) were Hispanic, 26% (n = 16) Asian, 29% (n = 18) Black, 38% (n = 23) White, and 7% (n = 4) identified with more than one race. ColorMeter lightness (L*) and melanin measures were strongly correlated with both Munsell and Pantone values. Munsell skin tone groups were not aligned with Eumelanin Scale groupings. Most participants were in the Eumelanin intermediate-low group, and this changed depending on which body location melanin value was used. The change in erythema from baseline did not differ significantly across skin tone groups at the ulnar head, but on the forearm at the delayed time point, significant differences existed between light and both medium and dark skin tone groups (P = .001; 95% CI, 0.04-0.37). CONCLUSIONS: The ColorMeter provides an effective objective measure of skin tone and erythema/discoloration across various skin tones and may improve on current standards for detection. The proposed Eumelanin Scale-Modified provides additional sensitivity for persons with medium skin tones.

Pressure Injury Data Reconciliation in a Randomized Controlled Trial.

OBJECTIVE: To advance pressure injury (PrI) research in individuals with spinal cord injury (SCI) by describing lessons learned and recommendations for future research, ultimately promoting PrI prevention and more effective wound care. This paper describes the detailed procedures undertaken to collect and reconcile PrI data and summarizes the types of discrepancies identified. DESIGN: Secondary analyses of PrI data collected between 2009 and 2014 in a randomized controlled trial (parent study). SETTING: Participants in the parent study were recruited from a large rehabilitation center in the Los Angeles area that serves primarily individuals with limited resources. PARTICIPANTS: 232 participants with SCI and a history of 1 or more medically serious PrI (MSPrI) in the previous 5 years. INTERVENTIONS: Participants in the parent study were randomized to a 12-month PrI prevention intervention led by an occupational therapist, or to usual care. MAIN OUTCOME MEASURES: Relations among PrI characteristics, data sources (phone interviews, skin checks, paper and electronic medical records [MRs]), and treatment condition, and sensitivity of 6 different data sources in detecting MSPrIs. RESULTS: The majority (62%) of MSPrIs were in the pelvic region. MRs detected 82% of the MSPrIs overall, making it the most sensitive data source, and scheduled skin checks were the second-most sensitive data source, finding 37% of the MSPrIs. CONCLUSIONS: MR review is the preferred method for ascertaining MSPrIs in clinical trials of interventions designed to reduce the incidence of these injuries. When multiple sources of information are used, careful reconciliation of reports is necessary to ensure accuracy.

Soccer-related injuries utilization of U.S. emergency departments for concussions, intracranial injuries, and other-injuries in a national representative probability sample: Nationwide Emergency Department Sample, 2010 to 2013.

Soccer participation in the United States (U.S.) has increased over time, and injuries as well as interest to prevent injuries has become more common. This study described Emergency Department (ED) visits related to concussions, intracranial injuries (ICI), and all-other injuries attributed to soccer play; described healthcare cost and length of hospital stay of soccer-related injuries; and determined independent predictors of concussions, ICI, and all-other soccer injuries leading to ED visits. The study examined soccer-related weighted discharge data from the Nationwide Emergency Department Sample, Healthcare Cost and Utilization Project, Agency for Healthcare Research and Quality. Weighted tabular analysis of univariate and bivariate analyses and weighted and adjusted logistic regression models were conducted. A total of 480,580 of U.S. ED visits related to soccer injuries were available for analysis between 2010 to 2013. Generally, 98% of soccer-related ED visits resulted in routine (treat-and-release) visits. However, the odds of transfer to a short-term hospital following ED evaluation and treatment was more than 37-fold higher for soccer-injured youth and adults diagnosed with ICI when compared to all-other soccer injuries; additionally, these patients showed 28-fold higher odds of being admitted for inpatient care at the ED-affiliated hospital. For concussion, soccer-injured patients with concussion showed nearly 1.5-fold higher odds of being transferred to a short-term hospital than did those with any other soccer injury. Soccer-related ED visits cost more than 700 million in U.S. dollars from 2010 to 2013. Notable differences were noted between concussions, ICI, and all-other soccer injuries presenting to U.S. ED. Albeit underestimated given that this study excludes other forms of health care and treatment for injuries, such as outpatient clinics, over the counter medications and treatment, and rehabilitation, healthcare cost associated with soccer-related injuries presenting to ED is high, and remarkably costly in those with an ICI diagnosis.

The identification of biophysical parameters which reflect skin status following mechanical and chemical insults.

BACKGROUND: Skin is constantly exposed to mechanical and chemical insults, in the form of prolonged loading, overhydration or exposure to irritants. An array of non-invasive biophysical tools has been adopted to monitor the changes in skin response. The present study aims to identify a set of robust parameters sensitive to mechanical and chemical challenges to skin integrity. MATERIALS AND METHODS: Eleven healthy participants were recruited to evaluate the skin response following mechanical loading, tape stripping, overhydration and chemical irritation. Forearm skin responses were recorded at baseline and at three time points following the insult. Measurements included transepidermal water loss, sub-epidermal moisture, erythema and laser Doppler imaging. Thresholds were informed by basal values, and the sensitivity of parameters to detect skin changes was evaluated. RESULTS: High degree of variability in skin response was observed with selected biophysical parameters, such as sub-epidermal moisture, laser Doppler imaging and erythema, even in the absence of an applied insult. Temporal skin response revealed distinct response profiles during each evoked insult. Indeed, the sensitivity of the biophysical parameters was influenced by the threshold values and time point of measurement. Some statistically significant correlations were determined between the biophysical parameters. CONCLUSION: The study revealed that thresholds derived from single biophysical parameters were limited in detecting skin changes following insults. A complementary evaluation using combined parameters has the potential to provide a more sensitive assessment. Further research is required to identify robust biophysical parameters, to aid the early detection of skin damage in clinical settings.

Anatomical variability of sub-epidermal moisture and its clinical implications.

BACKGROUND: Technologies have been developed to monitor changes in dermal oedema, indicative of the early signs of pressure ulcers. However, there is limited information on the effects of regional differences in tissue morphology on these sub-epidermal moisture (SEM) parameters. This study was designed to investigate the absolute SEM readings across different anatomical sites using a commercial device. METHODS: Twenty-four healthy participants were recruited to evaluate basal SEM values at different bony prominences, sampled by an experienced operator. RESULTS: Distinct differences were observed in unloaded SEM values across different anatomical sites, notably between the upper and lower extremities. A high degree of variability was observed in particular sites, such as the heels. Moreover, SEM values at certain locations revealed significant relationships with age, BMI and gender (p < 0.05). CONCLUSION: The study revealed a high level of variability between and within anatomical sites in a healthy cohort of participants. Determining the changes in local skin and sub-dermal tissue status using SEM may require consideration of both site specific and individual demographic factors, with further research needed in cohorts at risk of pressure ulcers.

Developing a decision support tool to prevent community-acquired pressure injuries in spinal cord injury in ambulatory care: A nurse-led protocol for mix methods research.

BACKGROUND: There is a lack of formal guidelines and decision support tools to prevent community-acquired pressure injuries (CAPrIs) in Veterans with spinal cord injury (SCI). PURPOSE: In this article we present our research protocol that describes our plans to create and test a decision support tool to prevent CAPrIs in SCI. METHODS: In Aim 1, we identified mental-models of CAPrI prevention from the perspectives of Veterans (using photovoice, guided tours), and Veterans Health Administration SCI providers (using interviews), and triangulation to compare the two mental-models. This led to a decision support tool developed and validated using Delphi approaches in Aim 2 and will be followed by tool automation and system redesign for pilot implementation in Aim 3. FINDINGS: The nurse-led research protocol provides a map to systematically explore, address and translate research into evidence-based practice. DISCUSSION: Refinement of the protocol will guide future research and implementation.

Natural History of Pressure Injury Among Ethnically/Racially Diverse Nursing Home Residents: The Pressure Ulcer Detection Study.

The current observational study provides descriptive data on 270 pressure injuries (PrIs) among 142 racially/ethnically diverse nursing home (NH) residents over 16 weeks. Weekly assessments were conducted with the Bates-Jensen Wound Assessment Tool. NH data were obtained from public government websites. NH, resident, and PrI characteristics across race/ethnicity groups were compared using analysis of variance and chi-square. Participants were 62% female and 89% functionally dependent. More Black and Asian individuals had peripheral vascular disease. More Black individuals had persistent trunk and Stage 4 PrIs. Black and Hispanic individuals had normal skin color surrounding PrIs. More Asian individuals had PrIs surrounded by purple/red discolored skin. More Black individuals' heel PrIs were unstageable, necrotic, and showed no granulation. Black and Hispanic individuals exhibited more deep tissue injury. No NH or prevention differences existed. Health disparities found validate administrative data results. Differences in PrI characteristics should be further examined among diverse NH residents. [Journal of Gerontological Nursing, 47(3), 37-46.].

Subepidermal Moisture and Pressure Injury in a Pediatric Population: A Prospective Observational Study.

PURPOSE: To describe relationships between subepidermal moisture (SEM) and visual skin assessment of pressure injury (PI) in children. DESIGN: Prospective descriptive study. SUBJECTS AND SETTING: Twenty-four participants aged 8 to 16 years recruited from a pediatric orthopedic unit in a children's hospital in Ireland. METHODS: Subepidermal moisture measured with the SEM scanner (Bruin Biometrics, Los Angeles, California) ranged from 0 to 7 picoFarads [pF], and visual observation of trunk and heels occurred daily for 3 days after admission to the unit and/or after surgery. Skin was assessed for discoloration categorized as blanchable erythema, stage 1 PI, or deep tissue injury (DTI). Any open wound PI was classified as stage 2, 3, 4, or unstageable. Demographic, medical, and pain data were collected. Chi-square test, t tests, analysis of variance, and regression were used to describe data and examine relationships. RESULTS: Participants were pediatric patients; 100% (n = 24) were white, 62% (n = 15) were female, 8 to 16 years of age (mean = 12.5 ± 2.5 years), and 29% (n = 7) had fractures and 71% (n = 17) surgery diagnoses. Blanchable erythema incidence was 21% (n = 5) and stage 1 PI incidence was 42% (n = 10); nearly all at heels. Deep tissue injury incidence was 4% (one sacral DTI). Stage 2 or greater PI incidence was 4% (one heel stage 2 PI). For skin that was assessed as normal in this pediatric population, SEM for trunk was 2.65 to 2.76 pF and for heels 2.37 to 2.41 pF. Subepidermal moisture for blanchable erythema and stage 1 PI was higher (range, 3.2-3.7 pF) and significant at trochanters and heels (left trochanter: P = .003; right trochanter: P = .02; right and left heels: P = .000). Nominal regression, controlling for participant and assessment day, showed SEM a predictor of erythema and stage 1 PI at heels. We also found that SEM was higher with pain (significant at sacrum and heels). CONCLUSIONS: In this pediatric population, SEM values over skin assessed as normal are lower than SEM values reported for normal skin in adults, 2.37 to 2.76 pF. Subepidermal moisture was significantly higher for blanchable erythema and stage 1 PI at trochanters and heels, and with the presence of pain at sacrum and heels. We recommend that SEM should be examined for detecting PIs in pediatric populations; SEM and pain should be explored in larger pediatric and adult populations.

Reliability of the Bates-Jensen wound assessment tool for pressure injury assessment: The pressure ulcer detection study.

The Bates-Jensen Wound Assessment Tool (BWAT) is used to assess wound healing in clinical practice. The purpose of this study was to evaluate BWAT use among nursing home residents with pressure injury. Findings and reliability estimates from the BWAT related to pressure injury characteristics (stage, anatomic location) and natural history (resolved, persisted) among 142 ethnically and racially diverse residents are reported. In this prospective 16-week study, 305 pressure injuries among 142 participants (34% prevalence) are described by stage, anatomic location, and BWAT scores. Visual and subepidermal moisture assessments were obtained from sacrum, buttock, ischial, and heel ulcers weekly. Participants were 14% Asian, 28% Black, 18% Hispanic, 40% White with a mean age of 78 ± 14 years, and were 62% female; 80% functionally dependent (bed mobility extensive/total assistance) and at risk (Braden Scale score 14 ± 2.7). The reliability coefficient for BWAT score (all participants, all anatomic locations) was high (r = 0.90; p < 0.0001; n = 1,161 observations). Weighted Kappas for characteristics ranging from 0.46 (skin color surrounding wound) to 0.79 (undermining) were consistent for all participants. BWAT scores showed strongest agreement coefficients for stage 4 pressure injury (r = 0.69), pressure injuries among Asian and White ethnicity/racial groups (r = 0.89, and r = 0.91, respectively), and sacrum anatomic location (r = 0.92) indicating scores are better correlated to fair skin tones. Lower agreement coefficients were demonstrated for stage 2 pressure injury (r = 0.38) and pressure injuries among African American and Hispanic ethnicity/racial groups (r = 0.88 and 0.87, respectively). BWAT scores were significantly different by pressure injury stage (F = 496.7, df = 6, p < 0.001) and anatomic location (F = 33.76, df = 8, p < 0.001). BWAT score correlated with pressure injury natural history (ulcer resolved 18.4 ± 7.4, ulcer persisted 24.9 ± 10.0; F = 70.11, df = 2, p < 0.001), but not with comorbidities. The BWAT provides reliable, objective data for assessing pressure injury healing progress.

Lifestyle intervention for adults with spinal cord injury: Results of the USC-RLANRC Pressure Ulcer Prevention Study.

CONTEXT/OBJECTIVE: Medically serious pressure injuries (MSPrIs), a common complication of spinal cord injury (SCI), have devastating consequences on health and well-being and are extremely expensive to treat. We aimed to test the efficacy of a lifestyle-based intervention designed to reduce incidence of MSPrIs in adults with SCI. DESIGN: A randomized controlled trial (RCT), and a separate study wing involving a nonrandomized standard care control group. SETTING: Rancho Los Amigos National Rehabilitation Center, a large facility serving ethnically diverse, low income residents of Los Angeles County. PARTICIPANTS: Adults with SCI, with history of one or more MSPrIs over the past 5 years: N=166 for RCT component, N=66 in nonrandomized control group. INTERVENTIONS: The Pressure Ulcer Prevention Program, a 12-month lifestyle-based treatment administered by healthcare professionals, largely via in-home visits and phone contacts. OUTCOME MEASURES: Blinded assessments of annualized MSPrI incidence rates at 12 and 24 months, based on: skin checks, quarterly phone interviews with participants, and review of medical charts and billing records. Secondary outcomes included number of surgeries and various quality-of-life measures. RESULTS: Annualized MSPrI rates did not differ significantly between study groups. At 12 months, rates were .56 for intervention recipients, .48 for randomized controls, and .65 for nonrandomized controls. At follow-up, rates were .44 and .39 respectively for randomized intervention and control participants. CONCLUSIONS: Evidence for intervention efficacy was inconclusive. The intractable nature of MSPrI threat in high-risk SCI populations, and lack of statistical power, may have contributed to this inability to detect an effect. TRIAL REGISTRATION: ClinicalTrials.gov NCT01999816.

Subepidermal moisture detection of heel pressure injury: The pressure ulcer detection study outcomes.

We examined subepidermal moisture (SEM) and visual skin assessment of heel pressure injury (PrI) among 417 nursing home residents in 19 facilities over 16 weeks. Participants were older (mean age 77 years), 58% were female, over half were ethnic minorities (29% African American, 12% Asian American, 21% Hispanic), and at risk for PrI (mean Braden Scale Risk score = 15.6). Blinded concurrent visual assessments and SEM measurements were obtained at heels weekly. Visual skin damage was categorised as normal, erythema, stage 1 PrI, deep tissue injury (DTI) or stage 2 or greater PrI. PrI incidence was 76%. Off-loading occurred with pillows (76% of residents) rather than heel boots (21%) and often for those with DTI (91%). Subepidermal moisture was measured with a device where higher readings indicate greater moisture (range: 0-70 tissue dielectric constant), with normal skin values significantly different from values in the presence of skin damage. Subepidermal moisture was associated with concurrent damage and damage 1 week later in generalised multinomial logistic models adjusting for age, diabetes and function. Subepidermal moisture detected DTI and differentiated those that resolved, remained and deteriorated over 16 weeks. Subepidermal moisture may be an objective method for detecting PrI.

Subepidermal moisture detection of pressure induced tissue damage on the trunk: The pressure ulcer detection study outcomes.

We examined the relationship between subepidermal moisture measured using surface electrical capacitance and visual skin assessment of pressure ulcers at the trunk location (sacral, ischial tuberosities) in 417 nursing home residents residing in 19 facilities. Participants were on average older (mean age of 77 years), 58% were female, over half were ethnic minorities (29% African American, 12% Asian American, and 21% Hispanic), and at risk for pressure ulcers (mean score for Braden Scale for Predicting Pressure Ulcer Risk of 15.6). Concurrent visual assessments and subepidermal moisture were obtained at the sacrum and right and left ischium weekly for 16 weeks. Visual assessment was categorized as normal, erythema, stage 1 pressure ulcer, Deep Tissue Injury or stage 2+ pressure ulcer using the National Pressure Ulcer Advisory Panel 2009 classification system. Incidence of any skin damage was 52%. Subepidermal moisture was measured with a dermal phase meter where higher readings indicate greater moisture (range: 0-70 tissue dielectric constant), with values increasing significantly with the presence of skin damage. Elevated subepidermal moisture values co-occurred with concurrent skin damage in generalized multinomial logistic models (to control for repeated observations) at the sacrum, adjusting for age and risk. Higher subepidermal moisture values were associated with visual damage 1 week later using similar models. Threshold values for subepidermal moisture were compared to visual ratings to predict skin damage 1 week later. Subepidermal moisture of 39 tissue dielectric constant units predicted 41% of future skin damage while visual ratings predicted 27%. Thus, this method of detecting early skin damage holds promise for clinicians, especially as it is objective and equally valid for all groups of patients.

Difficulty in Identifying Factors Responsible for Pressure Ulcer Healing in Veterans With Spinal Cord Injury.

OBJECTIVE: To identify characteristics associated with pressure ulcer (PrU) healing for individuals with spinal cord injury (SCI). DESIGN: Secondary analysis of a large clinical trial's data for healing PrUs in individuals with SCI; prospective Delphi process was conducted with SCI and/or PrU experts. SETTING: Spinal cord injury centers. PARTICIPANTS: There were 629 screening and 162 treatment participants (N=791); 185 SCI clinicians/national PrU/wound care experts participated in the Delphi process. INTERVENTIONS: None. MAIN OUTCOME MEASURE: PrU healing of 50% and 100% at weeks 4 and 12. RESULTS: Poisson regression models using the top Delphi-recommended factors found that only ulcer stage consistently predicted 50% and 100% healing at weeks 4 and 12. Additionally, ischial/perineal location was associated with 33% higher likelihood of 50% healing at week 4. Patient noncompliance with treatment recommendations, the top-ranked Delphi factor, did not predict healing at week 4 or 12. Expanded models found that at week 4, baseline PrU size, PrU stage IV, PrU pain, and American Spinal Injury Association grade A significantly predicted 100% healing, while at week 12, only PrU stage (IV) significantly predicted 100% healing. Significant predictors of 50% healing at week 4 included baseline PrU size, stage, ischial/perianal location body mass index >30kg/m2, foul odor, and signs of infection. At week 12, PrU duration, paraplegia predicted 50% healing. SCI center identifiers consistently showed 2- to 5-fold variation in predicting 50% PrU healing at weeks 4 and 12. CONCLUSIONS: Delphi panel-recommended factors (eg, patient compliance) did not predict PrU healing. Reducing center-level variability in wound healing by learning from best practices should be a health system goal. PrU healing in SCI is still poorly understood, and future studies should focus on as yet unidentified or underappreciated factors.

Data and Doing: Using Wound Size to Evaluate Wound Care in Venous Ulcers.

Measuring and monitoring wound progress by size are an important management tool. Wound progress and size can help assess effectiveness of therapy and predict healing, while preparing for application of advanced wound products and treatments. The authors outline methods of tracking wound size and predictors of healing in venous leg ulcers.
