Development and Psychometric Evaluation of a Medical Device–Related Pressure Injury Risk Assessment Scale

ABSTRACT

Medical device–related pressure injuries are a significant and largely preventable patient safety problem, yet existing pressure injury risk scales do not adequately capture device-specific risk factors in adults. This methodological study developed and psychometrically evaluated a standardized risk assessment scale to identify medical device–related pressure injury risk in hospitalized adult patients. An initial item pool was generated from an extensive literature review and clinical expertise, and content validity was assessed by seven experts using the Davis technique (content validity index = 0.96). The scale was administered to 160 adults receiving at least one medical device in medical, surgical and oncology wards and intensive care units of a university hospital. Construct validity was evaluated using binary logistic regression, exploratory factor analysis, and receiver operating characteristic curve analysis, demonstrating strong discrimination (area under the curve = 0.844, 95% confidence interval 0.728–0.961) with an optimal cut-off score of 14.5 (sensitivity 70.6%, specificity 88.8%). Exploratory factor analysis of the final version of the MedRAS (Kaiser-Meyer-Olkin = 0.792) revealed a two-factor structure (Device and Mechanical Factors; Patient and Tissue Factors) explaining 50.92% of the total variance, with all factor loadings above 0.30. The scale showed good internal consistency (Cronbach's alpha = 0.80) and very good inter-rater reliability (Cohen's kappa = 0.806, p < 0.001). This device-focused scale may support early risk identification and targeted preventive nursing interventions, with potential to improve patient safety and quality of care in inpatient/critical care settings.

Body Mass Index: A Key Factor in Surgical Site Infections After Kidney Transplantation?

ABSTRACT

Kidney transplant recipients are at increased risk of surgical site infections (SSIs) due to procedural complexity and immunosuppression. This retrospective single-centre study examines the influence of BMI on SSI risk and identifies common pathogens. A total of 230 renal transplant patients were included in this analysis 2017 and 2019. All patients received a cephalosporin for prophylaxis, and wound swabs were taken from those who developed SSIs. SSIs occurred in 45 patients (19.6%) and were not significantly associated with age, sex or donor type. The most common organisms were coagulase-negative staphylococci (26.7%), Staphylococcus epidermidis (24.4%), Enterococcus faecalis (22.2%) and Candida albicans (22.2%). SSIs were significantly linked to surgical revision (p < 0.001) and higher BMI (p = 0.027). A BMI ≥ 28.1 was associated with threefold higher odds of SSIs (OR = 3.0; p = 0.001). Each one-unit increase in BMI was associated with a 7.2% increase in the odds of SSI occurrence (OR = 1.072; p = 0.020). Staphylococcus (p = 0.019) and Enterococcus (p = 0.048) infections were more common in patients with BMI > 28.1. Therefore, SSIs are a frequent complication posttransplant and are strongly associated with high BMI. Standard antibiotic regimens may not cover all relevant pathogens in obese patients, underscoring the need for tailored prophylactic strategies.

Racial and Skin Tone Differences in Scar Maturation: A Prospective Analysis of Aesthetic and Physiological Outcomes Using the Modified POSAS Scale

ABSTRACT

Scar outcomes are known to vary by skin tone and race, yet few studies have systematically evaluated these differences using validated tools. To evaluate differences in scar maturation across Fitzpatrick skin types and racial groups from 3 to 12 months postoperatively using the modified Patient and Observer Scar Assessment Scale (POSAS) scale. We conducted a prospective observational study of 40 patients undergoing breast surgery at a single academic centre. All scars were assessed at 3 and 12 months postoperatively using the modified POSAS. Fitzpatrick skin types were categorized into I–II, III–IV, and V–VI, and racial groups included Caucasian, Black, and Hispanic patients. Fitzpatrick Types I–II had the greatest vascularity reduction (–2.06 ± 2.10), while Types V–VI showed the least improvement (–0.80 ± 1.61). Pigmentation increased in Types V–VI (+0.35 ± 1.89) and improved in lighter skin tones. Black and Hispanic patients had significantly lower odds of favourable pigmentation outcomes (p < 0.07). Fitzpatrick Types V–VI also had lower odds of improved scar relief (OR = 0.125, p = 0.034). This study highlights differences in scar maturation across skin tone and racial categories using a standardized scale. These trends underscore the importance of tailoring postoperative scar counselling and interventions to individual patients’ skin types and racial backgrounds.

Assessing the Clinical and Cost Effectiveness of Dialkylcarbamoylchloride (DACC) Coated Post‐Operative Dressings Versus Standard Care in the Prevention of Surgical Site Infection in Clean or Clean‐Contaminated, Vascular Surgery (DRESSINg Trial): Study

ABSTRACT

Surgical site infections (SSI) in vascular surgery have a huge impact on patients’ morbidity and mortality and healthcare systems worldwide. Dialkylcarbamoylchoride (DACC) is a synthetically produced material that can irreversibly bind and inactivate bacteria that exhibit cell-surface hydrophobicity (CSH). The DACC in the Reduction of Surgical Site Infection (DRESSINg) trial is a multicentre randomised controlled trial which aims to assess the effectiveness of DACC-coated post-operative dressings in the prevention of SSI in vascular surgery. Seven hundred and eighteen participants undergoing clean or clean-contaminated lower limb vascular surgery will be randomised in a 1:1 ratio to either DACC-coated dressings or standard dressings for their postoperative wounds. The primary outcome is the incidence of SSI defined by the Centers for Disease Control and Prevention (CDC) criteria or total ASEPSIS score of 21 or more within 30 days of surgery. The secondary outcomes include satisfactory wound healing with a total ASEPSIS score of 10 or less, quality of life pre and post surgery, Bluebelle wound healing scores, resource use and financial (£), and environmental (KgCO2e) cost analyses. This multicentre randomised controlled trial will provide level 1 evidence on the effectiveness of preventing SSI in lower limb vascular surgery.

The Barriers and Facilitators to Implementing Pressure Injury Prevention Strategies: A Qualitative Study Among Nursing Home Staff in Sri Lanka

ABSTRACT

Preventing pressure injuries among nursing home residents is a significant challenge that necessitates understanding the barriers and facilitators from the perspective of staff. This qualitative study aimed to describe these factors within Sri Lankan nursing homes. Semi-structured interviews were conducted with 15 nursing home staff members from nine nursing homes in and near the Colombo district, Sri Lanka. The study was informed by the capability, opportunity, motivation, and behaviour model that guided both data collection and analysis. Data were analysed using content analysis. Using deductive coding based on capability, opportunity, and motivation, followed by inductive analysis, four primary categories emerged: focusing on skincare is foundational for pressure injury prevention, pressure injury knowledge is critical for prevention, pressure injury prevention is a low organisational priority, and overcoming challenges to enact pressure injury prevention. Key facilitators included access to skincare products, maintaining clean and dry skin, recognising risk factors, proactively managing risks, and understanding the broader implications of pressure injuries on residents and their families. Conversely, barriers encompassed limited training, varying staff support, inadequate resources, and the complexities of managing multiple tasks. This research highlights that enhancing knowledge and allocating resources effectively can improve the implementation of pressure injury prevention strategies in Sri Lankan nursing homes.
