Relationship between cleaning frequency and pressure ulcer healing time in older people receiving home care.

OBJECTIVE: The relationship between the healing time of pressure ulcers (PUs) and wound cleaning frequency among older people in homecare settings was investigated. METHOD: This single-centre, prospective cohort study was conducted from April 2018 to March 2019. Patients who used home-visit nursing services, had National Pressure Ulcer Advisory Panel classification stage 2 PUs, and had their wounds cleaned at least twice a week were enrolled in the study. Wound cleaning was performed using tap water and a weakly acidic cleanser. Participants were divided into two groups, determined by the frequency of wound cleaning (twice weekly versus ≥3 times weekly). Duration of PU healing and the increase in care insurance premiums were compared in both groups. RESULTS: A total of 12 patients were included in the study. The mean healing period of PUs cleaned ≥3 times per week (65.3±24.8 days) was significantly shorter than that of PUs cleaned twice a week (102.6±19.2 days; p<0.05). Furthermore, the increase in care insurance premiums for PUs cleaned ≥3 times per week (¥122,497±105,660 Yen per six months) was significantly lower than that for PUs cleaned twice a week (¥238,116±60,428 per six months) (p<0.05). CONCLUSION: Our results suggest that frequent cleaning of PUs by health professionals in homecare settings not only shorten PU healing period but also reduces care insurance premiums for PU care.

Pressure ulcer development in patients treated for acute ischaemic stroke.

OBJECTIVE: The aim of this study was to determine the incidence of pressure ulcers (PUs) in patients treated for acute ischaemic stroke (AIS) and to evaluate comorbid/confounding factors. METHOD: The study included patients treated for AIS who were divided into three treatment groups: those receiving intravenous tissue plasminogen activator therapy (tPA); patients receiving mechanical thrombectomy (MT); and those receiving both tPA and MT. PUs were classified according to the international classification system and factors that may influence their development were investigated. RESULTS: A total of 242 patients were included in this study. The incidence of PUs in patients treated for AIS was 7.4%. Most PUs were located on the sacrum (3.7%), followed by the gluteus (3.3%) and trochanter (2.9%). With regards to PU classification: 29% were stage I; 34% were stage II; and the remainder were stage III. Age was not a significant factor in the development of PUs (p=0.172). Patients in the tPA group had a lower PU incidence (2.3%) than patients in the tPA+MT group (15.7%) and MT group (12.1%) (p=0.001). Patients with PUs had a longer period of hospitalisation (18.5±11.92 days) than patients without a PU (8.0±8.52 days) (p=0.000). National Institute of Health Stroke Scale (NIHSS) scores at admission were higher in patients with PUs than in patients without a PU (14.33±4.38 versus 11.08±5.68, respectively; p=0.010). The difference in presence of comorbidities between patients with and without PUs (p=0.922) and between treatment groups (p=0.677) were not statistically significant. The incidence of PUs was higher in patients requiring intensive care, but this difference was not statistically significant (p=0.089). CONCLUSION: In this study, patients treated for AIS with high NIHSS scores at admission and/or receiving MT were at higher risk for PUs, and so particular attention should be given to these patients in order to prevent PU development.

Pressure ulcers related to prone positioning: a pandemic amidst a pandemic.

OBJECTIVE: To explore the epidemiology and risk factors associated with the development of pressure ulcers (PUs) in patients receiving prone positioning (PP) ventilatory therapy; to compare the inflammatory status of patients who develop PUs with those who do not; and to describe the experience and useful findings that have allowed us to improve the management of these patients to reduce the incidence of PUs. METHOD: An observational, descriptive and longitudinal study was conducted, where sociodemographic and laboratory data were collected from patients who were hospitalised and required PP ventilatory therapy in critical care areas (CCA) during the months of May-October 2020. RESULTS: From the total number of patients who required PP during their CCA stay (n=240), 202 (84.2%) developed a PU. The four most frequent areas where a PU appeared were: the head and neck (n=115); the pinna (n=21); the torso (n=21); and the lower limbs (n=21). Patients who developed PU were more frequently males with higher initial levels of creatinine phosphokinase and ferritin. The incidence for each month of follow-up decreased from 8.3% to 5.8%. CONCLUSION: Regardless of the intervention, a multidisciplinary approach is required to optimise the prevention and treatment of these wounds. While PUs are often the result of other medical conditions or poor health status in general, the vast majority of PUs are avoidable.

Dynamic Microcirculation Characteristics of Plantar Skin Under Metatarsal Head of Human Foot in Response to Life-Like Pressure Stimulus.

OBJECTIVE: Diabetic foot ulcer (DFU) is a severe complication with high mortality. High plantar pressure and poor microcirculation are considered main causes of DFU. The specific aims were to provide a novel technique for real-time measurement of plantar skin blood flow (SBF) under walking-like pressure stimulus and delineate the first plantar metatarsal head dynamic microcirculation characteristics because of life-like loading conditions in healthy individuals. METHODS: Twenty young healthy participants (14 male and 6 female) were recruited. The baseline (i.e., unloaded) SBF of soft tissue under the first metatarsal head were measured using laser Doppler flowmetry (LDF). A custom-made machine was utilized to replicate daily walking pressure exertion for 5 min. The exerted plantar force was adjusted from 10 N (127.3 kPa) to 40 N (509.3 kPa) at an increase of 5 N (63.7 kPa). Real-time SBF was acquired using the LDF. After each pressure exertion, postload SBF was measured for comparative purposes. Statistical analysis was performed using the R software. RESULTS: All levels of immediate-load and postload SBF increased significantly compared with baseline values. As the exerted load increased, the postload and immediate-load SBF tended to increase until the exerted load reached 35 N (445.6 kPa). However, in immediate-load data, the increasing trend tended to level off as the exerted pressure increased from 15 N (191.0 kPa) to 25 N (318.3 kPa). For postload and immediate-load SBF, they both peaked at 35 N (445.6 kPa). However, when the exerted force exceeds 35 N (445.6 kPa), both the immediate-load and postload SBF values started to decrease. CONCLUSIONS: Our study offered a novel real-time plantar soft tissue microcirculation measurement technique under dynamic conditions. For the first metatarsal head of healthy people, 20 N (254.6 kPa)-plantar pressure has a fair microcirculation stimulus compared with higher pressure. There might be a pressure threshold at 35 N (445.6 kPa) for the first metatarsal head, and soft tissue microcirculation may decrease when local pressure exceeds it.

A systematic review on the impact of sub-epidermal moisture assessments on pressure ulcer/injury care delivery pathways.

To assess all published studies which describe what happens to the delivery of pressure ulcer/injury (PI/PU) care pathways as a result of detecting raised sub-epidermal moisture (SEM) delta (∆ ≥ 0.6). We undertook a systematic review of the literature, and included original research studies using either a prospective or retrospective study design that report the impact that assessment using SEM assessments have on healthcare practitioners' delivery of PI/PU care pathways in adults at risk of developing PI/PUs. The review protocol was registered on PROSPERO (CRD42023416975). A literature search was conducted in May 2023, using PubMed, CINAHL, Scopus, Cochrane, EMBASE, Web of Science and Science Direct databases. Data were extracted using a data extraction tool including elements such as country, setting, sample size, intervention, control and quality appraisal was undertaken using the Evidence-based Librarianship. We identified nine papers published between 2017 and 2022. The majority of these studies were conducted in England (n = 6; 67%). The systematic review included studies conducted across multiple care settings including acute care, medical-surgical units, and palliative care, highlighting the importance of PI/PU prevention and management across diverse patient populations. The PI/PU care pathways implemented in the studies varied, but commonly included elements such as the application or increased use of pressure-redistributing mattresses/cushions, implementation of repositioning plans, management of incontinence and moisture, regular skin inspection, and assessment of patient mobility. Out of the nine studies identified, seven reported PI/PU incidence. A meta-analysis of seven studies (N = 18 451) demonstrated a statistically significant reduction in visual PI/PU development in favour of SEM-guided care pathways compared to usual care (the odds ratio = 0.36 [95% confidence interval: 0.24-0.53, p < 0.00001]). This systematic review provides evidence that implementing SEM assessments in patients at risk of developing PI/PUs prompts anatomy-specific clinical actions. The subsequent implementation of enhanced and targeted skin care interventions leads to consistent and sustained reductions in hospital-acquired PU incidence. The findings emphasise the importance of incorporating SEM assessments as part of comprehensive PI/PU prevention strategies in all care settings and patient populations. This systematic review is limited by the predominance of observational studies and variable study quality. Future research should focus on randomised trials in different care settings that monitor the efficacy of preventive interventions and their impact in reducing PI/PU incidence when implemented based on SEM assessments.

Piperacillin/tazobactam-induced sudden severe thrombocytopenia in a patient with a pressure ulcer: a case report.

The standard treatment for an infected pressure ulcer (PU) with osteomyelitis is debridement, wound coverage and antibiotic administration. However, systemic administration of antibiotics in patients with osteomyelitis is controversial, and the optimal treatment duration for chronic osteomyelitis has not been standardised. We report a case of sudden severe thrombocytopenia induced by piperacillin/tazobactam (PIPC/TAZ) in a patient with PU-related osteomyelitis. A 57-year-old male patient with paraplegia, using a wheelchair full-time, presented to our plastic surgery department with infection of a stage IV hard-to-heal ischial PU. We surgically debrided the necrotising tissue and raised an ipsilateral biceps femoris musculocutaneous propeller flap for wound coverage. Polymicrobial infections, including Pseudomonas aeruginosa, were detected in the bone biopsy sample; therefore, systemic PIPC/TAZ was administered for the osteomyelitis. Unexpectedly, during the next 12 days of antibiotic administration, the patient's platelet count acutely dropped to 1×103/µl over three days. Based on a series of examinations, PIPC/TAZ was suspected to be the most likely cause of the severe thrombocytopenia. After drug discontinuation, the thrombocytopenia gradually improved. PIPC/TAZ is one of the most widely used antibiotic combinations in the plastic surgery field; it is conventionally administered for hard-to-heal wounds such as PUs and diabetic foot. The present case suggests that surgeons must take special precautions for patients undergoing PIPC/TAZ treatment. In this report, PIPC/TAZ-induced thrombocytopenia and the efficacy of antibiotic treatment for PU-related osteomyelitis are discussed in light of the available literature.

The rat as an animal model in chronic wound research: An update.

The increasing global prevalence of chronic wounds underscores the growing importance of developing effective animal models for their study. This review offers a critical evaluation of the strengths and limitations of rat models frequently employed in chronic wound research and proposes potential improvements. It explores these models in the context of key comorbidities, including diabetes, venous and arterial insufficiency, pressure-induced blood flow obstruction, and infections. Additionally, the review examines important wound factors including age, sex, smoking, and the impact of anesthetic and analgesic drugs, acknowledging their substantial effects on research outcomes. A thorough understanding of these variables is crucial for refining animal models and can provide valuable insights for future research endeavors.

Is the varying management of incontinence-associated dermatitis due to a lack of understanding of etiology?

Incontinence-associated dermatitis, previously and sometimes still referred to as moisture lesions or moisture damage, is a commonly seen contact dermatitis that is a reactive response of the skin to chronic contact to urine and faecal matter. Understanding the etiology is fundamental to creating a skin care plan and successfully prevention. Systemic reviews and studies have shown that the continued variability in management results from a combination of knowledge base, observation, diagnosis, and product selection. This article aims to improve clinicians' understanding of incontinence-associated dermatitis and its management.

Bedsore Healing Using Selenium-Enriched Lactobacillus brevis LSe: A Randomized, Double-Blind, Controlled Clinical Trial.

Bedsores impose an important challenge to the healthcare system. Se-baring probiotics are considered effective agents in wound healing and inflammation reduction via several pathways. The present study focused on the administration of a Se-enriched probiotic, originally obtained from a traditional dairy product for bedsore healing. Daily doses of the probiotic were administered to 20 ICU patients for 14 days and the wound healing criteria were compared with those of the same group of ICU patients as control, both groups suffering from stages I and II bedsore (a randomized, double-blind, controlled clinical trial). The administered Se-enriched probiotic decreased the bedsore healing period significantly (on average by 2.4 days, P-value: 0.039), as well as bedsore size (on average by 7 mm2, nonsignificant) and bedsore grade (10%, nonsignificant) in the treatment group more efficiently than the control group. Some key laboratory parameters associated with inflammation were also improved in patients receiving the Se-supplemented probiotic. The limitations of this study include the low number of patients meeting inclusion criteria within the timeframe of the study, and the impossibility of following up patients after discharge from the ICU. In summary, this study revealed the effectiveness of the Se-enriched probiotic in bedsore improvement, suggesting consideration of the enriched probiotic as an auxiliary agent in bedsore management.

Is Shock Wave Application Effective on Various Chronic Wounds in the Geriatric Population? Preliminary Clinical Study.

Purpose: Extracorporeal shock wave therapy (ESWT) is a beneficial adjunct modality for chronic wounds. Limited research has been conducted on pressure ulcers (PUs), while the majority of studies have focused on diabetic foot ulcers (DFUs) and venous leg ulcers (VLUs). This study aimed to evaluate the short-term effects of radial ESWT in older adults with chronic wounds. Patients and Methods: This study involved a total of 31 wounds: PUs (n=22), VLUs (n=7), and DFUs (n=2). A single radial ESWT was performed with 300 + 100 shocks per cm2, pressure of 2.5 bar, energy of 0.15 mJ/mm2, and frequency of 5 Hz. Assessments using digital planimetry and clinical methods, utilizing the Wound Bed Score (WBS) and the Bates-Jansen Wound Assessment Tool (BWAT) were performed before the radial ESWT application (M0) and one week after (M1). Results: A significant wound decrease in planimetry was noted (pre-ESWT vs post-ESWT), with wound area from 9.4 cm2 to 6.2 cm2, length from 6.4 cm to 3.9 cm, and width from 2.8 cm to 2.1 cm (p<0.001). Additionally, a substantial clinical improvement was noted in both the WBS with a 31.25% increase and the BWAT with a 20.00% increase (p<0.001). It was also found a significant correlation between the planimetric and clinical outcomes for both tools: WBS (r=-0.446, p=0.012) and BWAT (r=0.327, p=0.073). Conclusion: The ESWT application yields substantial immediate clinical effects that support the healing of chronic wounds in older adults. Even a single ESWT session can prove to be clinically effective and beneficial in the management of chronic wounds.

Prediction Pressure Ulcers in High Care Unit Patients: Evaluating Risk Factors and Predictive Scale Using a Prospective Cross-Sectional Study.

Background The incidence of ulcer pressure in the high care unit (HCU) was relatively high and could be reliably predicted using tools such as the Norton and Jackson/Cubbin scales. However, other risk factors, such as age, gender, consciousness, systemic condition, duration of treatment, and use of restraint, may contribute to the occurrence of ulcer pressure. This study was conducted to analyze the relationship of various risk factors for pressure ulcers and prediction of ulcer pressure, using Norton and Jackson/Cubbin scale, to incident pressure ulcers in HCU patient. Methods This study utilized a prospective cross-sectional study design to analyze various risk factors for ulcer pressure development in a patient admitted to the HCU, including age, gender, blood profile, consciousness, duration of treatment, and use of restraint. The Norton and Jackson/Cubbin scale was employed to predict pressure ulcers. The relationship between the risk factors and the prediction of pressure ulcer incidents was evaluated using multiple logistic binary regression analysis. Result Both the Norton and Jackson/Cubbin scales predicted a lower risk of pressure ulcer development (60.98 and 99.02%, respectively). This prediction is consistent with the low incidence of pressure injuries found, which is only 4.39%. Furthermore, the relationship between the identified risk factor (gender, duration of treatment in HCU and use of restraint) and the prediction and incident of pressure ulcer was not significant ( p > 0.05). Thus, it is suggested that these risk factors may not strong predictors of pressure ulcer development. Conclusion This study's result indicated no significant relationship exists between possible identified risk factors and the development of pressure ulcers in HCU patients. However, the Norton and Jackson/Cubbin scales were reliable predictors of pressure ulcer occurrence, with both scales predicting a lower risk of pressure ulcer development.

Pressure injury treatment by intermittent electrical stimulation (PROTECT-2): protocol for a multicenter randomized clinical trial.

BACKGROUND: Pressure ulcers account for a substantial fraction of hospital-acquired pathology, with consequent morbidity and economic cost. Treatments are largely focused on preventing further injury, whereas interventions that facilitate healing remain limited. Intermittent electrical stimulation (IES) increases local blood flow and redistributes pressure from muscle-bone interfaces, thus potentially reducing ulcer progression and facilitating healing. METHODS: The Pressure Injury Treatment by Intermittent Electrical Stimulation (PROTECT-2) trial will be a parallel-arm multicenter randomized trial to test the hypothesis that IES combined with routine care reduces sacral and ischial pressure injury over time compared to routine care alone. We plan to enroll 548 patients across various centers. Hospitalized patients with stage 1 or stage 2 sacral or ischial pressure injuries will be randomized to IES and routine care or routine care alone. Wound stage will be followed until death, discharge, or the development of an exclusion criteria for up to 3 months. The primary endpoint will be pressure injury score measured over time. DISCUSSION: Sacral and ischial pressure injuries present a burden to hospitalized patients with both clinical and economic consequences. The PROTECT-2 trial will evaluate whether IES is an effective intervention and thus reduces progression of stage 1 and stage 2 sacral and ischial pressure injuries. TRIAL REGISTRATION: ClinicalTrials.gov NCT05085288 Registered October 20, 2021.

Performance of artificial intelligence chatbots in interpreting clinical images of pressure injuries.

To evaluate the accuracy of AI chatbots in staging pressure injuries according to the National Pressure Injury Advisory Panel (NPIAP) Staging through clinical image interpretation, a cross-sectional design was conducted to assess five leading publicly available AI chatbots. As a result, three chatbots were unable to interpret the clinical images, whereas GPT-4 Turbo achieved a high accuracy rate (83.0%) in staging pressure injuries, notably outperforming BingAI Creative mode (24.0%) with statistical significance (p < 0.001). GPT-4 Turbo accurately identified Stages 1 (p < 0.001), 3 (p = 0.001), and 4 (p < 0.001) pressure injuries, and suspected deep tissue injuries (p < 0.001), while BingAI demonstrated significantly lower accuracy across all stages. The findings highlight the potential of AI chatbots, especially GPT-4 Turbo, in accurately diagnosing images and aiding the subsequent management of pressure injuries.

Development and validation of a nomogram for oral mucosal membrane pressure injuries in ICU patients: A prospective cohort study.

AIMS: Establishing a nomogram to estimate the probability of oral mucosal membrane pressure injury of endotracheal tube-intubated hospitalized patients in intensive care unit. DESIGN: Multicentre prospective cohort study. METHODS: Using Lasso regression and COX regression, variable selection was performed on demographic, clinical and laboratory data of 1037 ICU endotracheal tube-intubated hospitalized patients from West China Hospital, to construct a nomogram. External validation was conducted on 484 ICU endotracheal tube-intubated patients from People's Hospital of Zhongjiang County. RESULTS: Among 38 potential predictors, five variables emerged as independent predictors, integrated into the nomogram: administration of antibiotics, nutritional therapy duration, agitation, hypotension and albumin levels. CONCLUSIONS: We established a nomogram based on the hospital characteristics of ICU endotracheal tube-intubated patients, aiding in the prediction of the occurrence of oral mucosal membrane pressure injury. REPORTING METHOD: The study followed TRIPOD guidelines. RELEVANCE TO CLINICAL PRACTICE: The nomogram we developed can assist clinical worker in better identifying at-risk patients and risk factors. It enables the implementation of evidence-based nursing interventions in care to prevent the development of oral mucosal membrane pressure injury. TRIAL REGISTRATION: The study has been registered with the Chinese Clinical Trial Registry (http://www.chictr.org.cn) under registration number ChiCTR2200056615.

In vivo mechanical response of thigh soft tissues under compression: A two-layer model allows an improved representation of the local tissue kinematics.

Biomechanical parameters have the potential to be used as physical markers for prevention and diagnosis. Finite Element Analysis (FEA) is a widely used tool to evaluate these parameters in vivo. However, the development of clinically relevant FEA requires personalisation of the geometry, boundary conditions, and constitutive parameters. This contribution focuses on the characterisation of mechanical properties in vivo which remains a significant challenge for the community. The aim of this retrospective study is to evaluate the sensitivity of the computed elastic parameters (shear modulus of fat and muscle tissues) derived by inverse analysis as a function of the geometrical modelling assumption (homogenised monolayer vs bilayer) and the formulation of the cost function. The methodology presented here proposes to extract the experimental force-displacement response for each tissue layer (muscle and fat) and construct the associated Finite Element Model for each volunteer, based on data previously collected in our group (N = 7 volunteers) as reported in (Fougeron et al., 2020). The sensitivity analysis indicates that the choice of the cost function has minimal impact on the topology of the response surface in the parametric space. Each surface displays a valley of parameters that minimises the cost function. The constitutive properties of the thigh (reported as median ± interquartile range) were determined to be (µ=198±322Pa,α=37) for the monolayer and (µmuscle=1675±1127Pa,αmuscle=22±14,µfat=537±1131Pa,αfat=32±7) for the bilayer. A comparison of the homogenised monolayer and bilayer models showed that adding a layer reduces the error on the local force displacement curves, increasing the accuracy of the local kinematics of soft tissues during indentation. This allows for an increased understanding of load transmission in soft tissue. The comparison of the two models in terms of strains indicates that the modelling choice significantly influences the localization of maximal compressive strains. These results support the idea that the biomechanical community should conduct further work to develop reliable methodologies for estimating in vivo strain in soft tissue.

Clinical evaluation of continuous irrigation with Bikerui combined with negative pressure closed drainage and platelet-rich plasma technique for treatment of stage III-IV pressure ulcer.

Introduction: As a catastrophic complication of bedridden and elderly patients, pressure ulcer usually continuously affects patients' health and quality of life, so the daily care of wounds is attached great importance in clinic. Aim: This work investigated the effect of Bikerui disinfectant + vacuum sealing drainage (VSD) + platelet-rich plasma (PRP) therapy on patients with stage III ~ IV pressure sore. Material and methods: In this work, 110 patients with pressure ulcer (PU) treated in our hospital were enrolled and were randomly divided into an experimental group (Exp group) and a control group (Ctrl group) by a blind selection method, with 55 cases in each group. Patients in the Ctrl group received surgical debridement + VSD for treatment, while those in the Exp group were treated with Bikerui disinfectant + VSD + PRP. Inflammatory response (IR) score, PU healing (PUH) score, healing time, dressing change frequency (DCF), dressing interval time (DIT), and scar recovery (SR) score of patients in different groups were compared. Results: The results revealed that the positive rate of bacterial culture in wound secretions in the Exp group was greatly lower than that in the Ctrl group 1 or 2 weeks after treatment (p < 0.05). The IR score in the Exp group was much lower at week 1 and 2 after treatment (p < 0.05). The total effective rate (TER) in the Exp group was obviously higher than that in the Ctrl group (94.55% vs. 76.36%). Conclusions: The results suggested that Bikerui disinfectant + VSD + PRP therapy could effectively improve the inflammatory degree of PU patients, promote the wound repair and scar recovery of patients, and greatly improve the clinical efficacy of PU patients.

Development and validation of a risk prediction model for community-acquired pressure injury in a cancer population: A case-control study.

BACKGROUND: Patients with cancer are susceptible to pressure injuries, which accelerate deterioration and death. In patients with post-acute cancer, the risk of pressure injury is ignored in home or community settings. OBJECTIVE: To develop and validate a community-acquired pressure injury risk prediction model for cancer patients. METHODS: All research data were extracted from the hospital's electronic medical record system. The identification of optimal predictors is based on least absolute shrinkage and selection operator regression analysis combined with clinical judgment. The performance of the model was evaluated by drawing a receiver operating characteristic curve and calculating the area under the curve (AUC), calibration analysis and decision curve analysis. The model was used for internal and external validation, and was presented as a nomogram. RESULTS: In total, 6257 participants were recruited for this study. Age, malnutrition, chronic respiratory failure, body mass index, and activities of daily living scores were identified as the final predictors. The AUC of the model in the training and validation set was 0.87 (95 % confidence interval [CI], 0.85-0.89), 0.88 (95 % CI, 0.85-0.91), respectively. The model demonstrated acceptable calibration and clinical benefits. CONCLUSIONS: Comorbidities in patients with cancer are closely related to the etiology of pressure injury, and can be used to predict the risk of pressure injury. IMPLICATIONS FOR PRACTICE: This study provides a tool to predict the risk of pressure injury for cancer patients. This suggests that improving the respiratory function and nutritional status of cancer patients may reduce the risk of community-acquired pressure injury.

Fatores preditores associados a ocorrência de lesão por pressão em pacientes em cuidados paliativos oncológicos / Predictive factors associated with the occurrence of pressure injuries in patients undergoing cancer palliative care / Factores predictivos asociados con la aparición de lesiones por presión en pacientes sometidos a cuidados paliativos oncológicos

A realist evaluation of devices used for the prevention of heel pressure ulcers: An ethnographic study of clinical practice.

BACKGROUND: It is known that heel offloading devices are widely used in clinical practice for the prevention of heel pressure ulcers, even though there is a lack of robust, good quality evidence to inform their use. OBJECTIVE: To explore how and why heel offloading devices are used (or not used) and reasoning behind their use in population at high risk of developing heel pressure ulcers. METHODS: An ethnographic study was conducted as part of a realist evaluation in three orthopaedic wards in a large English hospital. Twelve observations took place, with 49 h and 35 min of patient care observed. A total of 32 patients were observed and 19 members of the nursing team were interviewed and in-depth interviews with the three ward managers were conducted. RESULTS: Although the focus of the study was on offloading devices, constant low pressure heel specific devices were also observed in use for pressure ulcer prevention, whilst offloading devices were perceived to be for higher risk patients or those already with a heel pressure ulcer. Nursing staff viewed leadership from the ward manager and the influence of the Tissue Viability Nurse Specialists as key mechanisms for the proactive use of devices. CONCLUSIONS: This study informs trial design as it has identified that a controlled clinical trial of both types of heel specific devices is required to inform evidence-based practice. Involving the ward managers and Tissue Viability Nurse Specialists during set up phase for clinical equipoise could improve recruitment. Tweetable abstract How, for whom, and in what circumstances do devices work to prevent heel pressure ulcers? Observations of clinical practice.

Nursing care bundles in the prevention of medical device related pressure ulcers: An integrative review.

The aim of this integrative review was to explore the effect of care bundles in the prevention of Medical Device Related Pressure Ulcers (MDRPU). An MDRPU is a wound that occurs on the skin or mucosal membranes because of pressure or pressure in combination with shear. Like other types of pressure ulcers, they will have negative consequences for patients and healthcare organisations alike. Many MDRPU's are preventable. A literature search was undertaken from computerised databases using key search terms, Pressure Ulcer* Pressure Injur* and Medical Device*. Databases included CINAHL; Medline and SocIndex. A total of seven studies were found that met the criteria for inclusion in this review. When compared to the widely recognised and trusted international guidelines there was variation found between the individual interventions selected within each study for inclusion within the bundle. Skin assessment and device repositioning were the most frequently included interventions in the bundles, followed by use of prophylactic dressings, appropriate device selection and fitting. The least common intervention was monitoring the tension of the device and/or its securements. All studies reported a reduction in the number of MDRPU's when care bundles were used in clinical practice. However, there is variation in bundle designs and study methodologies employed. This review has demonstrated the potential benefit of care bundles in reducing MDRPU. However, due to heterogeneity in the study methods employed and the interventions within the care bundles, further, more robust research is required to establish which interventions show the most clinical and patient benefit.
