RESUMEN

OBJECTIVE: The aim of this study was to measure wound pH, wound temperature and wound size together to gain further understanding of their impact as predictors of wound healing outcomes. METHOD: This study employed a quantitative non-comparative, prospective, descriptive observational design. Participants with both acute and hard-to-heal (chronic) wounds were observed weekly for four weeks. Wound pH was measured using pH indicator strips, wound temperature was measured using an infrared camera and wound size was measured using the ruler method. RESULTS: Most of the 97 participants (65%, n=63) were male; participant's ages ranged between 18 and 77 years (mean: 42±17.10. Most of the wounds observed were surgical 60%, (n=58) and 72% (n=70) of the wounds were classified as acute, with 28% (n=27) classified as hard-to-heal wounds. At baseline, there was no significant difference in pH between acute and hard-to-heal wounds; overall the mean pH was 8.34±0.32, mean temperature was 32.86±1.78°C) and mean wound area was 910.50±1132.30mm2. In week 4, mean pH was 7.71±1.11, mean temperature was 31.90±1.76°C and mean wound area was 339.90±511.70mm2. Over the study follow-up period, wound pH ranged from 5-9, from week 1 to week 4, mean pH reduced by 0.63 units from 8.34 to 7.71. Furthermore, there was a mean 3% reduction in wound temperature and a mean 62% reduction in wound size. CONCLUSION: The study demonstrated that a reduction in pH and temperature was associated with increased wound healing as evidenced by a corresponding reduction in wound size. Thus, measuring pH and temperature in clinical practice may provide clinically meaningful data pertaining to wound status.

RESUMEN

The aim of this feasibility study was to investigate the impact of inflammation management on wound pH, temperature, and bacterial burden, using the principles of TIME and Wound Bed Preparation. A quantitative non-comparative, prospective, descriptive observational design. Following ethical approval, 26 participants with 27 wounds of varying aetiologies were observed twice weekly for 2 weeks. Wounds were treated with cleansing, repeated sharp debridement, and topical cadexomer iodine. Wound pH (pH indicator strips), temperature (infrared camera), bacterial burden (fluorescence imaging) and size (ruler method) was monitored at each visit. The mean age of all participants was 47 years (SD: 20.3 years), and 79% (n = 19) were male, and most wounds were acute (70%; n = 19) and included surgical and trauma wounds, the remaining (30%; n = 8) were chronic and included vascular ulcers and non-healing surgical wounds. Mean wound duration was 53.88 days (SD: 64.49 days). Over the follow up period, pH values ranged from 6 to 8.7, temperature (centre spot) ranged from 28.4°C to 36.4°C and there was an average 39% reduction in wound size. Inflammation management had a positive effect on pH, temperature, bacterial burden, and wound size. This study demonstrated that it was feasible to practice inflammation management using a structured approach to enhance wound outcomes.

RESUMEN

This study aimed to investigate the impact of sub epidermal moisture (SEM) measurement and targeted pressure ulcer (PU) prevention, versus visual skin assessment and usual care, on mean SEM delta scores and early pressure ulcer development in acute hospital patients. A quantitative quasi-experimental observational approach was used. A total of 149 at risk acute hospital patients took part, 78 treatment, and 71 control. SEM deltas were recorded daily for a maximum of 5 days using the SEM Scanner (Bruin Biometrics LLC, Los Angeles, California), on three sites: the sacrum, the right heel, and the left heel, with enhanced and targeted PU prevention interventions occurring in those with an elevated SEM delta scores in the treatment group. Intention to treat analysis was used to guide the final composition of results. SEM PU represents PU development as identified by 2 days of sustained abnormal SEM delta scores, ≥0.5, after day one. The mean number of days completed by participants was just under 4 days, participants had many different comorbidities, with the most common being: hypertension, cancer, and chronic obstructive pulmonary disease. Results showed that following the introduction of SEM guided targeted treatments, participants in the treatment group yielded a statistically significant reduction in mean SEM delta scores (MD: 0.49; 95% CI: 0.59, 0.39; P < .0001), and in the odds of developing a SEM PU (OR: 0.59, 95% CI: 0.24 to 1.00; P = .05). In the treatment group, none of the participants developed a visual PU, whereas, in the control group, 1.41% (n = 1/71) developed a visual PU. Based on all the results, the following is concluded, (1). There was a greater reduction in mean SEM delta scores among those cared for using SEM measurement and targeted PU prevention, versus those cared for using visual skin assessment and usual care, and (2). the mean SEM delta scores was statistically significantly lower at the study end for those who received targeted treatments based on abnormal SEM scores. More research is now needed in other and larger at-risk groups to further validate what was found in this study.

RESUMEN

OBJECTIVE: To compare the predictive ability of subepidermal moisture (SEM) measurement versus traditional risk assessment and visual skin assessment (VSA) as means of detecting early pressure ulcer (PU) damage development among adults undergoing surgery. METHOD: A non-experimental, comparative, descriptive cohort study design was used. Following ethical approval, participants who had given their informed written consent had their skin assessed over the areas that were weight-bearing during surgery, using VSA and the SEM measurement. Visual PUs were graded according to the European Pressure Ulcer Advisory Panel and National Pressure Ulcer Advisory Panel ulcer grading system. Assessments took place preoperatively, then daily on the ward, beginning on day one postoperatively and continuing for three days or until discharge. RESULTS: Of the 231 participants, who had a mean age of 57.50 years, 55.8% (n=129) were male. The most common comorbidity was cardiology/vascular (n=42; 18.2%). Just over half (52.4%; n=121) underwent orthopaedic surgery and 47.6% (n=110) underwent non-orthopaedic surgery; 70% (n=163) received a general anaesthetic and 43% (n=100) were in the supine decubitus position during surgery. PU incidence was 51% (n=116), according to SEM measurement, and 3% (n=7) according to VSA. Among the seven participants who developed a visual PU, 10 PUs at stage 1 developed (31%); some patients developed more than one PU. Of the participants who had assessments for three days postoperatively, 94% (n=61) had a persistently high SEM delta on day three. The variables that emerged as statistically significantly related to abnormal SEM measurement deltas among these participants were: surgery duration (p=0.038); having orthopaedic surgery (p=0.020); supine surgical position (p=0.003); spinal anaesthetic type (p=0.0001); and Waterlow and Braden mobility subscale day one postoperatively (p=0.0001). None of the variables had a statistically significant influence on abnormal VSA. CONCLUSION: Surgical patients, because of immobility, are vulnerable to the action of compression and shear forces. These forces cause changes at a cellular level that trigger inflammation, which is a precursor to early tissue damage. SEM measurement can detect this tissue damage from the increase in the underlying tissue water content that results from inflammation. From the findings of this study, SEM measurement is very promising in the detection of early tissue damage in those at risk of PU development among the surgical population.

RESUMEN

To assess the impact of topical agents and dressings on surface wound pH, temperature, and subsequent wound healing. This was a systematic, narrative review of the literature, following the PRISMA (2020) guidelines. The databases searched were Medline PubMed, Cumulative Index to Nursing and Allied Health Literature (CINAHL), Cochrane Library, Embase, Web of Science, and Scopus. Data synthesis and analysis were conducted using a structured narrative synthesis. The quality of the included clinical studies was appraised using the Evidence-Based Literature (EBL) Critical Appraisal Tool. A total of six clinical studies were assessed as eligible for inclusion, A total of six dressings/topical agents were assessed and the types of wounds included non-healing chronic wounds. Of the studies, five explored pH and one explored temperature. The EBL validity of the clinical studies was low (mean quality score was 51.3%). The five clinical studies that explored pH investigated different dressings and topical agents reporting an associated reduction in pH and improved wound outcomes. One clinical study investigated the impact of topical sodium nitrite on temperature and found that sodium nitrite increased peri-wound skin temperature and improved wound outcomes with a reduction in leg ulcer size. Given the low certainty of the evidence, we cannot confidently recommend the use of any particular topical agent or dressing to manipulate pH, or temperature to improve wound outcomes. Thus, there is a need for further research to develop a greater understanding of this topic. Irish Research Council, Enterprise Partnership Scheme.

RESUMEN

OBJECTIVE: To test the feasibility of using a standardised data collection tool to estimate the cost of stage 2-4 pressure ulcer (PU) care within an acute care setting. METHOD: Data on resource use and cost were obtained through a retrospective survey of nursing and medical notes collecting cost data for individual patients who received care for stage 2-4 PUs. RESULTS: Data for 20 patients (12 male/8 female) were analysed. The average patient age was 69 years (range: 37-95 years). Of this sample, seven patients had hospital-acquired PUs (HAPUs) and 14 patients had community-acquired PUs (CAPU) (one patient had both-in different anatomical areas). Over half of the total sample (55%; n=11) had a stage 2 PU. The average length of stay was 31.8 days (range: 5-119 days). Most of the patients (70%; n=14) had a CAPU. The average cost per patient with PU care was €878 (range: €39-2393). The mean cost for patients with a HAPU was €866 (SD: €1313) versus €911 (SD: €567) for patients with a CAPU. The majority of the cost related to equipment and staff time for treatment. CONCLUSION: Overall, the application of the standardised data collection tool to obtain cost data from retrospective inspection of nursing and medical notes is feasible. The cost of PU care in this sample was high, indicating that these wounds may impose a substantial burden on health systems. The costs varied greatly between patients in the sample, reflecting the complexity of PU care. Furthermore, given that costs increased with the higher PU stages, there is a potential to reduce costs by preventing the development of higher stage PUs. Larger-scale studies are required to understand the cost variation and full economic impact of PU care. DECLARATION OF INTEREST: The authors have no conflicts of interest.

RESUMEN

AIM: This study explores the prevalence and management of wounds within an urban setting in Ireland. METHOD: It employs a cross-sectional survey design, using a predesigned, validated data-collection instrument. FINDINGS: The point prevalence of wounds was 3.7% (n=445), with surgical wounds being the most prevalent (43%; n=189). Wound care was provided across a wide variety of clinical settings, with the majority of patients (60%; n=271) managed in the acute care setting. Most dressings were changed 2-3 times a week (60%; n=271). The mean dressing time was 15 minutes (SD: 12.4 minutes), varying from 2 minutes to 90 minutes. The mean nurse travel time was 3 minutes (SD: 6.5 minutes), varying from 0-60 minutes. Among participants managed using silver and iodine dressings, 53% (n=10, silver) and 78% (n=50, iodine) were prescribed for wounds described as being not infected. Alginate dressings were used incorrectly in 75% of cases, foam dressings in 63% of cases and Hydrofiber dressings in 63% of cases. CONCLUSION: Wound management within the explored geographical area is an important clinical intervention. This study identified areas of practice that need to be addressed, primarily those related to the topical management of the wound and use of offloading. The data has been used to inform practice, education, and further research in this important clinical specialty.

RESUMEN

Wound healing is a normal response to injury and is initiated after the integrity of the skin has been interrupted. The management of exudate in practice can be challenging, as there are clinical situations where the patient's wound may produce copious amounts of exudate. It is therefore important that excess wound exudate is accurately assessed and diagnosed and subsequently managed effectively to relieve the significant burden it places on those who suffer with the problem. This article will look at the effect of Exufiber(®) in the management of three wounds with different aetiologies.

RESUMEN

AIM: This prospective observational study investigated wound area reduction (WAR) outcomes in a complex wound population composed of non-healing acute and chronic wounds. The relationship between bacterial autofluorescence signals and WAR was investigated. Area measurements were collected both manually and digitally, and both methods were compared for accuracy. METHODS: Twenty-six participants with 27 wounds of varying etiologies were observed twice weekly for two weeks. Digital wound measurement, wound bacterial status assessment, and targeted debridement were performed through a point-of-care fluorescence imaging device (MolecuLight® i: X, MolecuLight Inc, Toronto, Canada). The wound area reduction (WAR) rate was calculated using baseline and last visit measurements. Statistical analyses, including t-tests, Fisher exact tests, the Wilcoxon signed rank test for method comparison, and ANOVA for bacterial subgroups, were applied as pertinent. RESULTS: The overall average WAR was -3.80 cm2, or a decrease of 46.88% (manual measurement), and -2.62 cm2, or a 46.05% decrease (digital measurement via MolecuLight® device). There were no statistically significant differences between the WAR of acute and chronic wounds (p = 0.7877). A stepwise correlation between the WAR and bacterial status classification per fluorescence findings was observed, where persistent bacteria resulted in worse WAR outcomes. An overestimation of wound area by manual measurement was 23% on average. CONCLUSION: Fluorescence imaging signals were linked to WAR outcome and could be considered predictive. Wounds exhibiting bacterial loads that persisted at the end of the study period had worse WAR outcomes, while those for which management was able to effectively remove them demonstrated greater WAR. Manual measurement of the wound area consistently overestimated wound size when compared to digital measurement. However, if performed by the same operator, the overestimation was uniform enough that the WAR was calculated to be close to accurate. Notwithstanding, single wound measurements are likely to result in overestimation.

RESUMEN

AIM: To incorporate an international and multidisciplinary consensus in the determination of the research and education priorities for wound healing and tissue repair. BACKGROUND: A compelling reason for the study is the lack of an agreed list of priorities for wound care research and education. Furthermore, there is a growth in the prevalence of chronic wounds, a growth in wound care products and marketing, and an increase in clinician attendance at conferences and education programmes. DESIGN: The study used a survey method. METHODS: A four-round eDelphi technique was used to collect responses from an international population of health professionals across 24 countries. RESULTS: Responses were obtained from 360 professionals representing many health care settings. The top education priorities related to the standardisation of all foundation education programmes in wound care, the inclusion of wound care in all professional undergraduate and postgraduate education programmes, selecting dressings and the prevention of pressure ulcers. The top research priorities related to the dressing selection, pressure ulcer prevention and wound infection. conclusion: Professionals from different backgrounds and countries who are engaged in wound management share a common set of priorities for research and education. Most notably, the priorities identified relate to long-established clinical challenges in wound care and underpin the principles of good patient care practices. The priorities are closely allied to an ageing population and identify many challenges ahead for practitioners engaged in wound management services. RELEVANCE TO CLINICAL PRACTICE: The provision of wound care is a major investment of health service resources and remains a clinical challenge today. Research is essential to building evidence-based practice and fundamental to development of quality in standards of practice; education is central to achieving competence to deliver effective care. The determination of research and education priorities is therefore an absolute requirement in developing services.

RESUMEN

Lymphoedema is a chronic, incurable, debilitating condition, usually affecting a limb and causes discomfort, pain, heaviness, limited motion, unsatisfactory appearance and impacts on quality of life. However, there is a paucity of prevalence data on this condition. This study aimed to determine the prevalence of lymphoedema among persons attending wound management and vascular clinics in an acute tertiary referral hospital. Four hundred and eighteen patients meeting the inclusion criteria were assessed. A prevalence rate of 2.63% (n = 11) was recorded. Thirty-six percent (n = 4) had history of cellulitis and broken skin, 64% (n = 7) had history of broken skin and 36% (n = 4) had undergone treatment for venous leg ulcers. The most common co-morbidities were hypertension 55% (n = 6), deep vein thrombosis (DVT) 27% (n = 3), hypercholesterolemia 36% (n = 4) and type 2 diabetes 27% (n = 3). Quality of life scores identified that physical functioning was the domain most affected among this group. This study has identified the need to raise awareness of this condition among clinicians working in the area of wound management.
