The Effect of Intervention Program based on Interaction Model of Client Health Behavior on Patients of Pressure Injury.

Objective: To investigate the effect of the intervention program based on the Interaction Model of Client Health Behavior (IMCHB) in patients with pressure injury (PI). Methods: The First Affiliated Hospital of Qiqihar Medical University received thirty patients suspected of having pressure injuries from June to December 2022. These patients were selected as the control group. Another thirty patients suspected of having pressure injuries were received by the hospital from January to June 2023 and were selected as the experimental group. The experimental group received a usual care protocol, while the trial group received the IMCHB model intervention for three months. The study compared the knowledge of pressure injuries, quality of life, incidence of pressure injuries, and patient satisfaction of high-risk patients between the two groups. Results: After the intervention, the PI awareness score of caregivers in the experimental group was (31.90 ± 5.24). It is higher than the control group (26.37 ± 6.85). The point of social function, physical function and material function of experimental group were (57.03 ± 5.32), (33.47 ± 3.52) and (58.53 ± 6.93). Respectively, it was higher than the experimental group (48.63 ± 4.80), (27.17 ± 3.04), (46.13 ± 6.72). The incidence of high-risk PI in the experimental group was 3.33%. The point of the control group was 26.67%. The total satisfaction of the experimental group was (8.27 ± 0.78) points, higher than the control group (7.30 ± 0.65). The difference was of statistical significance (P < .05). Conclusion: The intervention program based on IMCHB can significantly improve cognitive ability and thus promote health behavior.

Nutritional interventions for preventing and treating pressure ulcers.

BACKGROUND: Pressure ulcers are localized injuries to the skin or the underlying tissue, or both, and are common in older and immobile people, people with diabetes, vascular disease, or malnutrition, as well as those who require intensive or palliative care. People with pressure ulcers often suffer from severe pain and exhibit social avoidance behaviours. The prevention and treatment of pressure ulcers involves strategies to optimize hydration, circulation, and nutrition. Adequate nutrient intake can reduce the risk factor of malnutrition and promote wound healing in existing pressure ulcers. However, it is unclear which nutrients help prevent and treat pressure ulcers. This is an update of an earlier Cochrane Review. OBJECTIVES: To evaluate the benefits and harms of nutritional interventions (special diets, supplements) for preventing and treating pressure ulcers in people with or without existing pressure ulcers compared to standard diet or other nutritional interventions. SEARCH METHODS: We used extensive Cochrane search methods. The latest search was in May 2022. SELECTION CRITERIA: We included randomized controlled trials (RCTs) in people with or without existing pressure ulcers, that compared nutritional interventions aimed at preventing or treating pressure ulcers with standard diet or other types of nutritional interventions. DATA COLLECTION AND ANALYSIS: We used standard Cochrane methods. Our primary outcome for prevention studies was the proportion of participants who developed new (incident) pressure ulcers. For treatment studies, our primary outcomes were time to complete pressure ulcer healing, number of people with healed pressure ulcers, size and depth of pressure ulcers, and rate of pressure ulcer healing. Secondary outcomes were side effects, costs, health-related quality of life and acceptability. We used GRADE to assess certainty of evidence for each outcome. MAIN RESULTS: We included 33 RCTs with 7920 participants. Data for meta-analysis were available from 6993 participants. Pressure ulcer prevention Eleven studies (with 12 arms) compared six types of nutritional interventions for the prevention of pressure ulcers. Compared to standard diet, energy, protein and micronutrient supplements may result in little to no difference in the proportion of participants developing a pressure ulcer (energy, protein and micronutrient supplements 248 per 1000, standard diet 269 per 1000; RR 0.92, 95% CI 0.71 to 1.19; 3 studies, 1634 participants; low-certainty evidence). Compared to standard diet, protein supplements may result in little to no difference in pressure ulcer incidence (protein 21 per 1000, standard diet 28 per 1000; RR 0.75, 95% CI 0.49 to 1.14; 4 studies, 4264 participants; low-certainty evidence). The evidence is very uncertain about the gastrointestinal side effects of these supplements (protein 109 per 1000, standard diet 155 per 1000; RR 0.70, 95% CI 0.06 to 7.96; 2 studies, 140 participants, very low-certainty evidence). The evidence is very uncertain about the effects of protein, arginine, zinc and antioxidants; L-carnitine, L-leucine, calcium, magnesium and vitamin D; EPA, GLA and antioxidants; disease-specific supplements on pressure ulcer incidence when compared to standard diet (1 study each; very low-certainty evidence for all comparisons). Pressure ulcer treatment Twenty-four studies (with 27 arms) compared 10 types of nutritional interventions or supplements for treatment of pressure ulcers. Compared to standard diet, energy, protein and micronutrient supplements may slightly increase the number of healed pressure ulcers (energy, protein and micronutrients 366 per 1000, standard diet 253 per 1000; RR 1.45, 95% CI 1.14 to 1.85; 3 studies, 577 participants, low-certainty evidence). The evidence is very uncertain about the effect of these supplements on gastrointestinal side effects. Compared to standard diet, the evidence is very uncertain about the effect of protein, arginine, zinc and antioxidant supplements on pressure ulcer healing (pressure ulcer area: mean difference (MD) 2 cm² smaller, 95% CI 4.54 smaller to 0.53 larger; 2 studies, 71 participants, very low-certainty evidence). The evidence on side effects of these supplements is very uncertain. Compared to standard diet, supplements with arginine and micronutrients may not increase the number of healed pressure ulcers, but the evidence suggests a slight reduction in pressure ulcer area (MD 15.8% lower, 95% CI 25.11 lower to 6.48 lower; 2 studies, 231 participants, low-certainty evidence). The evidence is very uncertain about changes in pressure ulcer scores, acceptability, and side effects of these supplements. Compared to placebo, collagen supplements probably improve the mean change in pressure ulcer area (MD 1.81 cm² smaller, 95% CI 3.36 smaller to 0.26 smaller; 1 study, 74 participants, moderate-certainty evidence). The evidence is very uncertain about the effect of these supplements on side effects. The evidence is very uncertain about the effects of vitamin C, different doses of arginine; EPA, GLA (special dietary fatty acids) and antioxidants; protein; a specialized amino acid mixture; ornithine alpha-ketoglutarate and zinc supplements on pressure ulcer healing (1 or 2 studies each; very low-certainty evidence). AUTHORS' CONCLUSIONS: The benefits of nutritional interventions with various compositions for pressure ulcer prevention and treatment are uncertain. There may be little or no difference compared to standard nutrition or placebo. Nutritional supplements may not increase gastrointestinal side effects, but the evidence is very uncertain. Larger studies with similar nutrient compositions would reduce these uncertainties. No study investigated the effects of special diets (e.g. protein-enriched diet, vegetarian diet) on pressure ulcer incidence and healing.

The Clinical and Cost-Effectiveness of an Individualized Nutritional CAre (INCA) Bundle versus Standard Care for Adults with Pressure Injuries Receiving Home Nursing Services: A Protocol for a Cluster Randomized and Pragmatic Clinical Trial with an Economic Evaluation.

BACKGROUND: Pressure injuries (PIs) represent a significant healthcare challenge in Singapore among the aging population. These injuries contribute to increased morbidity, mortality, and healthcare expenditure. Existing research predominantly explores single-component interventions in hospital environments, often yielding limited success. The INCA Trial aims to address this research gap by conducting a comprehensive, cluster randomized controlled trial that integrates education, individualized nutritional support, and community nursing care. This study is designed to evaluate clinical and cost-effectiveness outcomes, focusing on PI wound area reduction and incremental costs associated with the intervention. METHODS: The INCA Trial employs a two-group, non-blinded, cluster randomized, and pragmatic clinical trial design, recruiting 380 adult individuals (age ≥ 21 years) living in the community with stage II, III, IV, and unstageable PI(s) who are receiving home nursing service in Singapore. Cluster randomization is stratified by postal codes to minimize treatment contamination. The intervention arm will receive an individualized nutrition and nursing care bundle (dietary education with nutritional supplementation), while the control arm will receive standard care. The 90-day intervention will be followed by outcome assessments extending over one year. Primary outcomes include changes in PI wound area and the proportion of participants achieving a ≥40% area reduction. Secondary outcomes include health-related quality of life (HRQOL), nutritional status, and hospitalization rates. Data analysis will be conducted on an intention-to-treat (ITT) basis, supplemented by interim analyses for efficacy and futility and pre-specified sensitivity and subgroup analyses. The primary outcome for the cost-effectiveness analysis will be based on the change to total costs compared to the change to health benefits, as measured by quality-adjusted life years (QALYs). DISCUSSION: The INCA Trial serves as a pioneering effort in its approach to PI management in community settings. This study uniquely emphasizes both clinical and economic outcomes and melds education, intensive dietetic support, and community nursing care for a holistic approach to enhancing PI management.

Pressure injury prevention measures: overview of systematic reviews.

OBJECTIVE: Summarizing the evidence from systematic reviews regarding the comparison the effectiveness of interventions to prevent pressure injuries. METHOD: Overview of systematic reviews conducted in accordance with Cochrane guidelines. A search was performed in databases, repositories and systematic review registration sites. RESULTS: 15 reviews were included in this overview. The sensitivity analysis showed a reduction in the incidence of pressure injuries with nutritional supplementation compared to the standard hospital diet (Relative Risk (RR) = 0.83; 95% Confidence Interval (CI): 0.72-0.95). There was evidence of the superiority of constant low-pressure surfaces (RR = 0.38; 95% CI;0.24-0.61), alternating pressure devices (RR = 0.31; 95% CI:0.17-0.58) and alternative foams (RR = 0.40; 95% CI:0.21-0.74) when compared to the standard hospital mattress or standard foam. The use of a silicone cover reduced the incidence of pressure injuries by 75% (RR = 0.25; 95%CI:0.16-0.41) when compared to no cover. CONCLUSION: Although some interventions have been shown to be effective in reducing the incidence of pressure injury, the evidence is limited or very limited and subject to change.

Effect of Mind Map Health Education Mode on Prevention of Pressure Ulcers.

Objective: This work aimed to develop a pressure ulcer prevention nursing and health education strategy by using mind map techniques, apply the strategy to critically ill inpatients, and evaluate its effect on preventing pressure ulcers in patients. Methods: A study population of 82 critically ill hospitalized patients received random assignments to the control group (routine nursing intervention, n = 41) and the observation group (mental map health education based on the control group, n = 20). Patients in each group were then compared for the incidence and knowledge of pressure ulcers before and after nursing intervention and health education. Results: The awareness rates of pressure ulcer knowledge in the control and observation groups were 78.85% and 94.21%, respectively. The awareness rates of prevention knowledge after intervention were 79.8% and 94.38%, respectively (P < .05). The proportion of patients with a high risk of pressure ulcers in the observation group was lower than that in the control group (P < .05). The proportion of patients with a mild risk of pressure ulcers in the observation group was higher than in the control group (P < .05). Stage I pressure ulcers in the control and observation groups were 12.3% and 3.65%, respectively (P < .05). The incidence of stage II and above pressure ulcers in the control group and the observation group were 25.8% and 20.1%, respectively (P < .05). Conclusions: The mind map health education model helped improve patients' cognition level of pressure ulcers and enhanced their awareness of active cooperation, significantly preventing pressure ulcers.

Treatment of Recurrent Pressure Injury Using an Allograft Adipose Matrix.

ABSTRACT: A 77-year-old man with a more than 10-year history of a spinal cord injury developed bilateral trochanteric stage 3 pressure injuries (PIs) several years ago. They initially healed. The right trochanteric PI opened again and continued to reopen every 2 to 3 months, likely because of deficient adipose layer in the area of the healed PI.To treat the recurrent PI, providers injected a total of 3 mL of allograft adipose matrix into the ulcerated area of the right trochanter PI in a fanning fashion to increase subcutaneous cushioning over the bony prominence. Silicone foam was used to assist with pressure reduction for the first month. When the ulcerations healed at 1 month, the silicone foam was discontinued, and an emollient ointment was applied bilaterally to provide both the currently affected site and healed scar tissue with moisture and enhanced barrier function. Follow-up examinations were completed at 1, 3, 7, 11, 14, 16, 19, 22, and 24 months; the ulcerations remained closed, and no new PIs developed.The authors propose that allograft adipose matrix is a potential treatment modality for recurrent PIs needing a supplemented subcutaneous layer that other modalities cannot provide. Further use is ongoing in clinical scenarios when there is deficient adipose layer such as recurrent PIs or to prevent PI deterioration in early stages.

Impact of Nutrition on the Prevention and Treatment of Pressure Injuries in Critically Ill Patients: An Integrative Review.

OBJECTIVE: To review the main scientific evidence on nutrition in the prevention and treatment of pressure injuries (PIs) in critically ill adult patients. DATA SOURCES: The searches were carried out in several scientific databases, namely, Scientific Electronic Library Online (SciELO), Public MEDLINE (PubMed), Latin American and Caribbean Literature in Health Sciences (LILACS), and Web of Science. The MeSH terms used were "pressure injury", "nutrition", and "intensive care". STUDY SELECTION: Studies published between January 1, 2005, and July 1, 2020, were included. Seven studies met the eligibility criteria and were included in this review. The searches were carried out in August 2020. The authors selected studies available in Portuguese, English, and Spanish. DATA EXTRACTION: Two independent researchers conducted the searches and read the article titles and abstracts. The studies that met the inclusion criteria were fully evaluated. Disagreements between reviewers were resolved by consensus, and when there was no consensus, a senior researcher was consulted. Data extraction was performed using a standardized form. DATA SYNTHESIS: Level-of-evidence analysis according to the type of study followed the classification proposed by the Oxford Center Evidence-Based Medicine. The evidence available on the use of standard enteral nutrition therapy and enteral nutrition therapy enriched with hyperprotein and hypercaloric nutrition supplements as well as the addition of zinc, eicosapentaenoic acid, γ-linolenic acid, and vitamins (A, C, D, and E) is limited in terms of supporting a specific nutrition support modality in the prevention and treatment of PI in the intensive care population. CONCLUSIONS: Malnutrition negatively impacts both the prevention and healing of PIs. The evidence available on the use of standard enteral nutrition therapy versus enrichment with nutrition supplements is too limited to support a specific nutrition modality in the prevention and treatment of PI in the intensive care population.

Using Evidence to Prevent Risk Associated With Perioperative Pressure Injuries.

Pressure injuries (PI) are a significant concern for surgical patients due to prolonged immobility and potential exposure to other risk factors associated with procedures. PI prevention strategies should begin early in the patient's surgical encounter starting with preoperative assessment. Much literature has been published to discuss PI risk factors, assessment tools, and evidence-based prevention measures. The purpose of this article is to critically review current best evidence to holistically assess patient risk for Hospital Acquired Pressure Injuries (HAPI) and review current tools used for risk assessment, interventions to combat skin injuries, and discuss implications for practice in perioperative nursing.

Malnutrition and Pressure Injury Risk in Vulnerable Populations: Application of the 2019 International Clinical Practice Guideline.

ABSTRACT: Nutrition plays a vital role in promoting skin integrity and supporting tissue repair in the presence of chronic wounds such as pressure injuries (PIs). Individuals who are malnourished are at greater risk of polymorbid conditions, adverse clinical outcomes, longer hospital lengths of stay, PI development, and mortality, and incur increased healthcare costs compared with patients who are adequately nourished. In addition, some patient populations tend to be more vulnerable to PI formation, such as neonates, patients with obesity, older adults, and individuals who are critically ill. Accordingly, this article aims to review the latest nutrition care recommendations for the prevention and treatment of PIs, including those recommendations tailored to special populations. A secondary objective is to translate nutrition recommendations into actionable steps for the healthcare professional to implement as part of a patient plan of care.Implementing an evidence-based plan of care built around individualized nutrition interventions is an essential step supporting skin integrity for these populations. The 2019 Prevention and Treatment of Pressure Ulcers/Injuries: Clinical Practice Guideline (CPG) affirms that meeting nutrient requirements is essential for growth, development, maintenance, and repair of body tissues. Many macronutrients and micronutrients work synergistically to heal PIs. Registered dietitian nutritionists play an important role in helping patients identify the most nutrient dense foods, protein supplements, and oral nutrition supplements to meet their unique requirements.

Evidence-based review of the effects of nutritional supplementation for pressure ulcer prevention.

The objective of this evidence-based review was to explore whether the evidence supports the use of nutritional supplements in pressure ulcer (PU) prevention strategies. Several electronic databases, including Ovid MEDLINE (1946 to May week 32 019), Ovid EMBASE (1947 to May 28, 2019), EBSCO CINAHL (until June 13, 2019), Scopus (until July 9, 2019), and the Web of Science (until June 13, 2019) were searched. No limitation was placed on the year of publication. Studies considered for inclusion were those with adult populations, and only English language texts with available full text were reviewed. AMSTAR (a measurement tool to assess systematic reviews) was used to evaluate the quality of the studies included in the systematic review. The Oxford Centre for Evidence-Based Medicine (OCEBM) 2011 Levels of Evidence was used to assess the level of evidence. Appraisal of Guidelines for Research and Evaluation Instrument (AGREE II) was used to assess guideline article, and Appraisal tool for Cross-Sectional Studies (AXIS) was also used for cross-sectional studies. The search identified 1761 studies. After the application of inclusion and exclusion criteria, 24 studies were retained of various designs, including 10 systematic reviews, five clinical reviews, three randomised controlled trials, two observational studies, one quasi-experimental study, one cross-sectional study, one cohort study, and one Clinical Guideline. Two were rated as high-quality reviews, 14 were rated as moderate-quality reviews, five were rated as low-quality reviews, and three were rated as critically low-quality reviews. The majority of the reviewed studies were of low-to-moderate quality because of biases in the study design and incomplete data reporting, which did not fulfil the reporting criteria of the appraisal tools. However, the majority of the studies showed a reduction in PU incidence after nutritional supplement though not significant. Whether the use of pharmacological appraisal tools to assess non-pharmacological studies is appropriate is unclear. Regardless of the low-to-moderate quality of the studies in this review, nutritional supplements appear to play a role in PU prevention.

The influence of anaemia on pressure ulcer healing in elderly patients.

Anaemia is a common and multifactorial blood disorder in elderly individuals. This condition may be a significant barrier to pressure ulcers healing as it is associated with a decreased level of oxygen being supplied to body tissues. Some nutritional deficiencies such as iron, vitamin B12 and folate may also cause anaemia and have a negative impact on pressure ulcer healing. An increased iron demand in hard-to-heal pressure ulcers is a significant factor associated with the risk of anaemia of chronic disease in elderly patients. Anaemia screening and correction may need to be considered as well as iron supplementation if required in pressure ulcer prevention and management.

Cloves (Syzygium aromaticum) fluid gel on healing of pododermatitis in rabbits.

Wounds are damaging to quality life of confined animals, causing dysfunction in spinal, members injuries, and reduction in productive performance. This research investigated the clove antimicrobial and antioxidant activity on the healing of decubitus wounds (pododermatitis) of rabbits (Oryctolagus cuniculus). Adult animals were treated for 21 days every three days with a fluid gel spray in the wound region: control fluid gel without addition of clove (FGC0), fluid gel with addition of 1% clove powder (FGC1), and fluid gel with 2% clove powder (FGC2). Microbiological analysis for Escherichia coli and Pseudomonas spp. were performed during 21 days of experimental period. After this period, samples from treated skin were evaluated for histological analysis and evaluation of the healing process by spectroscopy (FTIR-ATR). Rabbits treated with FGC2 showed advanced healing and decreased tissue inflammation similar to healthy rabbits, while FGC0 rabbits showed a decrease in bacterial contamination without signs of healing. Both FGC1 and FGC2 rabbits demonstrated antimicrobial and antioxidant action against both bacteria tested, favoring the wound healing process. Considering the results, the use of fluid gel with 2% of clove powder (Syzigium aromaticum) based on the best antimicrobial, antioxidant and anti-inflammatory activities on healing of decubitus wounds (pododermatitis) of rabbits in commercial farming system.

The ELIAS framework: A prescription for innovation and change.

Healthcare is a complex adaptive system with multiple stakeholders and dynamic environments. Therefore, healthcare organizations must continuously learn, innovate, adapt, and co-evolve to be successful. This article describes a systematic, comprehensive, and holistic performance management framework that healthcare managers can use to achieve these goals. The framework involves the ongoing assessment, modification, or replacement of current programs or services aimed at adapting successfully to achieve the organization's strategic objectives. This is engendered by the presence of a culture that is premised on continuous learning and innovation. The foundation of the framework is based on accountability, the organization's strategy, and its culture. This then acts as the basis for an ongoing process of measurement, disconfirmation, contextualization, implementation, and routinization that enhances learning, innovation, adaptation, and sustainability within the healthcare organization.

Silicone adhesive multilayer foam dressings as adjuvant prophylactic therapy to prevent hospital-acquired pressure ulcers: a pragmatic noncommercial multicentre randomized open-label parallel-group medical device trial.

BACKGROUND: Silicone adhesive multilayer foam dressings are used as adjuvant therapy to prevent hospital-acquired pressure ulcers (PUs). OBJECTIVES: To determine whether silicone foam dressings in addition to standard prevention reduce the incidence of PUs of category 2 or worse compared with standard prevention alone. METHODS: This was a multicentre, randomized controlled medical device trial conducted in eight Belgian hospitals. At-risk adult patients were centrally randomized (n = 1633) to study groups based on a 1 : 1 : 1 allocation: experimental groups 1 (n = 542) and 2 (n = 545) - pooled as the treatment group - and the control group (n = 546). The experimental groups received PU prevention according to hospital protocol, and a silicone foam dressing on the relevant body sites. The control group received standard of care. The primary endpoint was the incidence of a new PU of category 2 or worse at the studied body sites. RESULTS: In the intention-to-treat population (n = 1605), PUs of category 2 or worse occurred in 4·0% of patients in the treatment group and 6·3% in the control group [relative risk (RR) 0·64, 95% confidence interval (CI) 0·41-0·99, P = 0·04]. Sacral PUs were observed in 2·8% and 4·8% of the patients in the treatment group and the control group, respectively (RR 0·59, 95% CI 0·35-0·98, P = 0·04). Heel PUs occurred in 1·4% and 1·9% of patients in the treatment and control groups, respectively (RR 0·76, 95% CI 0·34-1·68, P = 0·49). CONCLUSIONS: Silicone foam dressings reduce the incidence of PUs of category 2 or worse in hospitalized at-risk patients when used in addition to standard of care. The results show a decrease for the sacrum, but no statistical difference for the heel and trochanter areas.

Preventive effect of extra virgin olive oil on pressure injury development: A randomized controlled trial in Turkey.

BACKGROUND AND PURPOSE: Different moisturizing products are used in the prevention of pressure injuries, but there is a limited number of studies on the effectiveness of extra virgin olive oil, which is an herbal and natural product. The aim of this study was to examine the effect of topically applied extra virgin olive oil on the prevention of pressure injuries. METHODS AND MATERIALS: This was a randomized controlled experimental study conducted between February and October 2015 with a total of 129 patients, of whom 64 were in the control group and 65 in the extra virgin olive oil group. RESULTS: 16.9% of patients in the extra virgin olive oil group (n = 11) and 32.8% of patients in the control group (n = 21) developed pressure injuries, and the difference was found to be statistically significant. CONCLUSION: This study showed that the application of extra virgin olive oil is effective in preventing pressure injuries.

Critical biomechanical and clinical insights concerning tissue protection when positioning patients in the operating room: A scoping review.

An optimal position of the patient during operation may require a compromise between the best position for surgical access and the position a patient and his or her tissues can tolerate without sustaining injury. This scoping review analysed the existing, contemporary evidence regarding surgical positioning-related tissue damage risks, from both biomechanical and clinical perspectives, focusing on the challenges in preventing tissue damage in the constraining operating room environment, which does not allow repositioning and limits the use of dynamic or thick and soft support surfaces. Deep and multidisciplinary aetiological understanding is required for effective prevention of intraoperatively acquired tissue damage, primarily including pressure ulcers (injuries) and neural injuries. Lack of such understanding typically leads to misconceptions and increased risk to patients. This article therefore provides a comprehensive aetiological description concerning the types of potential tissue damage, vulnerable anatomical locations, the risk factors specific to the operative setting (eg, the effects of anaesthetics and instruments), the complex interactions between the tissue damage risk and the pathophysiology of the surgery itself (eg, the inflammatory response to the surgical incisions), risk assessments for surgical patients and their limitations, and available (including emerging) technologies for positioning. The present multidisciplinary and integrated approach, which holistically joins the bioengineering and clinical perspectives, is unique to this work and has not been taken before. Close collaboration between bioengineers and clinicians, such as demonstrated here, is required to revisit the design of operating tables, support surfaces for surgery, surgical instruments for patient stabilisation, and for surgical access. Each type of equipment and its combined use should be evaluated and improved where needed with regard to the two major threats to tissue health in the operative setting: pressure ulcers and neural damage.

Effect of intraoperative pressure ulcer preventive nursing on inflammatory markers in patients with high-risk pressure ulcers: A protocol of systematic review and meta-analysis.

BACKGROUND: This study will be designed to appraise the effects of intraoperative pressure ulcer preventive nursing (IPUPN) on inflammatory markers (IMs) in patients with high-risk pressure ulcers (HRPU) based on high quality randomized controlled trials (RCTs). METHODS: In this study, we will perform a rigorous literature search from the following electronic databases: Cochrane Library, MEDLINE, Embase, Cumulative Index to Nursing and Allied Health Literature, Allied and Complementary Medicine Database, and Chinese Biomedical Literature Database. All electronic databases will be retrieved from their initial time to March 1, 2020 without limitations of language and publication status. We will only consider high quality RCTs that explored the effects of IPUPN on IMs in patients with HRPU. Two investigators will identify relevant trials, extract data, and appraise risk of bias in each eligible trial. Data will be pooled by either a fixed-effects model or a random-effects model according to the results of heterogeneity identification. The primary outcomes include IMs, and incidence of new pressure ulcers. The secondary outcomes are time to ulcer development, quality of life, length of hospital stay, and adverse events. Statistical analysis will be undertaken using RevMan 5.3 software. RESULTS: This study will summarize high quality clinical evidence of RCTs to evaluate the effects of IPUPN on IMs in patients with HRPU. CONCLUSION: The expected findings may provide helpful evidence to determine whether IPUPN is an effective intervention on IMs in patients with HRPU. INPLASY REGISTRATION NUMBER: INPLASY202040029.

Topical Almond Oil for Prevention of Pressure Injuries: A Single-Blinded Comparison Study.

PURPOSE: The aim of our study was to determine the effect of topical almond oil for prevention of pressure injuries. DESIGN: Single-blind randomized clinical trial. SAMPLE AND SETTING: Patients admitted to an intensive care unit in Besat Hospital, Hamadan, Iran, were invited to participate in the trial. Data were collected over an 8-month period. METHODS: A convenience sample of 108 patients, using a permuted block randomization method was assigned to 3 equal groups that received the intervention almond oil, placebo (liquid paraffin), or control (standard of care). Data included demographic information, Braden Scale score, and National Pressure Ulcer Advisory Panel-European Pressure Ulcer Advisory Panel (NPUAP-EPUAP) pressure injury staging system classification score. The intervention and placebo groups received daily application of 6.5 cc of topical almond oil or paraffin to the sacrum, heels, and shoulders for 7 consecutive days. The skin was evaluated for pressure injuries by an expert nurse who was blinded to groups. Chi-square test, analysis of variance, and regression analyses were used to evaluate relationships within and between groups for study variables, incidence of pressure injuries, and duration of time of onset of pressure injuries. P values less than .05 were deemed statistically significant. RESULTS: The incidence of pressure injury in the almond oil group (n = 2; 5.6%) was lower than that in the placebo (n = 5; 13.9%, P = .189) or control groups (n = 9; 25.1%, P = .024). The incidence of pressure injuries in the control group was 6.8 and 2.12 (P = .227) times higher than that in the almond and placebo groups, respectively. The onset day of a pressure injury occurred 5.4 days after initiation of the protocol in the almond oil group compared to 4.22 days in the control group (P = .023) and 5 days in the placebo group (P = .196). CONCLUSION: The topical application of almond oil was associated with a lower incidence of pressure injuries and that developed later during the study compared to participants who received paraffin or standard of care only. Further study is recommended to advance this work in populations at risk for pressure injury.

Feasibility of overnight electrical stimulation-induced muscle activation in people with a spinal cord injury. A Pilot study.

Study Design: We investigated whether overnight ES is a feasible method to activate gluteal, quadriceps, and hamstrings muscles in a two-week experiment. Electrical stimulation (ES) induced muscle contractions have proven positive effects on risk factors for developing pressure ulcers in people with a spinal cord injury (SCI). Therefore prolonged overnight ES-induced muscle activation is interesting, but has never been studied. Objective: To study feasibility of ES-induced leg muscle activation. In eight participants with motor complete SCI gluteal, hamstrings and quadriceps muscles were activated with a 2-weeks overnight stimulation protocol, 8 h per night, using specially developed ES-shorts. Setting: The Netherlands. Methods: Muscle fatigue was determined with a muscle contraction sensor. Questionnaires on sleep quality (SQ) and the ES-shorts usability were taken. Results: After 8 h of activation muscles still contracted, although fatigue occurred, and mean contraction size was lower at the end of a cycle (p = 0.03). SQ (0-100) after intervention was 75, and 66 after 4 weeks without overnight ES (p = 0.04) indicating ES improves sleep quality. The usability of the ES-shorts was good. Conclusions: This study shows that overnight ES-induced muscle activation using ES-shorts in SCI is a new, feasible method that does not interfere with sleep. The nightly use of the ES-shorts might be considered as an important part of the daily routine in SCI.
