Evaluation of final-year nursing students' attitudes towards preventing medical device‐related pressure ulcers using a ABC model of affect, behavior and cognitive dimensions

IntroductionHalf of the hospital-acquired pressure ulcers are associated with the use of medical devices. Nursing students provide care services to patients in clinical settings and intensive care units who have or are at risk for medical device-related pressure ulcers (MDRPUs). In the prevention and care of MDRPUs, the attitudes of nursing students towards preventing of pressure ulcers are as crucial as their knowledge level and clinical skills. AimThe aim of this descriptive study is to assess the attitudes of final-year nursing undergraduate students towards preventing MDRPUs across cognitive, affective, and behavioral dimensions of ABC model. Materials and methodsData of the study was handed between April 1 and December 31, 2021, with 147 final-year nursing students. Data were collected using the Student Information Form and the Attitude Towards Preventing Medical Device-Related Pressure Ulcers Questionnaire (ATP-MDRPUsQ). ResultsThe mean attitude score towards preventing MDRPUs was 3.98 ± 0.45 on a 5-point Likert scale. The mean scores for the cognitive, affective, and behavioral sub-dimensions were 3.88 ± 0.57, 4.15 ± 0.51, and 4.00 ± 0.672, respectively. A moderate positive relationship was found between the cognitive sub-dimension and both the affective and behavioral sub-dimensions (r = 0.451; r = 0.302; p < 0.01, respectively). Based on cluster analysis, the mean attitude scores of students towards MDRPU prevention were grouped into two clusters. The students in Cluster-2 and female students had higher mean attitude scores (p < 0.01). The item with the lowest mean score in the questionnaire pertained to the item, "I believe that I need training on the etiology and prevention of medical device-related pressure ulcers." ConclusionThe general attitudes of final-year nursing students towards prevention MDRPU were satisfactory. However, their cognitive attitudes were less positive compared to their affective and behavioral attitudes. It is recommended to incorporate theoretical and practical courses focusing on the prevention of these injuries into nursing curricula to enhance students' knowledge and attitudes.

Medical device-related pressure injuries in intensive care patients: A prospective and descriptive study

BackgroundTreatment and care of patients in intensive care units require the use of many medical and technological instruments. Pressure injuries occur when medical devices, which are used more in intensive care patients and are in direct or indirect contact with the skin, cause focal and localized forces on the superficial or deep tissues. ObjectiveIn this study, it was aimed to examine the risk factors, incidence and characteristics of medical device-related pressure injuries in intensive care patients. MethodsThis study has a prospective and descriptive design. The study was carried out in the adult intensive care unit of a healthcare institution located in the western Turkey. 138 intensive care patients treated in the level 3 adult intensive care unit were enrolled in the study. The first observations and evaluations of intensive care patients in terms of pressure injuries were made within the first 24 h after admission to the clinic. Observations continued daily during the hospitalization period of the patient. Data were collected with the Intensive Care Patient Information Form, Glasgow Coma Scale, Braden Pressure Ulcer Risk Assessment Scale and Identification Form for Medical device-related Pressure Ulcers. Analysis of data was performed with descriptive statistical methods, Shapiro-Wilk Test, Mann-Whitney U Test and Chi-Square analysis. ResultsMedical device-related pressure injury developed in 11.6% (n = 16) of intensive care patients. Anatomically, pressure injury occurred most frequently on the lip (37.5%) and most frequently due to the intubation tube (37.5%). Most of the developed wounds (75.0%) were found to be stage 2. Multinominal logistic regression analysis, which was performed to determine the effect of independent variables on medical device-related pressure injuries in intensive care patients, was found to be statistically significant (X2 = 37.098, p < 0.001). When the regression coefficients were examined, it was found that total hospitalization time in the intensive care unit (β = 0.948, p < 0.01) and PaCO2 level (β = 0.923, p < 0.01) had a positive, and duration of aerobic respiration with nasal cannula or mask (β = −0.920, p < 0.01) and Braden score (β = −0.948, p < 0.01) had a negative and significant effect on medical device-related pressure injuries. ConclusionsIn this study found that the MDRPIs development rate was lower than other studies. It was observed that pressure injuries due to medical devices developed more frequently in patients with longer hospitalization days, higher PaCO2 levels, shorter duration of oxygenated breathing with nasal cannula or mask, and lower Braden scores.

Study on an Onset Mechanism of MDRPU by Wearing Elastic Stockings: Numerical Simulation by Two-Dimensional Mechanical Model.

As compared with pressure injuries, the mechanism the development of medical device related pressure ulcers (MDRPU) is not revealed enough. According to studies on severity and frequent site of occurrence, MDRPUs are surmised to occur the surface of the skin. In this study, we assess theoretical and experimental analysis by two-dimensional mechanical model for elastic stockings (ES) wear the lower limbs with or without dug into the skin by the wrinkles and curling up of ES. The Finite Element Method (FEM) was used to calculate the stress on the skin and subcutaneous tissue, because of elucidating the mechanism of MDRPU. The FEM used a triple-layered cylindrical model simulating the skin, subcutaneous tissue, and bone. Regarding the interface pressure (compression pressure), two samples were created: the one is applying a uniform pressure of 5.3 kPa on the skin surface simulating the correct wearing of ES, and the other is applying a pressure of 16 kPa on the part of the skin on which ES dug in. The results were as follows: the internal stress on the skin and subcutaneous tissue was maximum at the site where ES dug in, producing stresses of 54 kPa, 50 kPa, and 21 kPa in the circumferential, longitudinal, and radial directions, respectively. The uniform pressure produced an internal stress of 5-9 kPa on the skin surface. Unlike the mechanism of pressure injury formation, we considered compressive strength from tensile of the circumferential and longitudinal directions, furthermore the additive radial pressure at the digging site on the skin due to the wrinkles and curling of ES, which is one of the factor to cause strong external force in the MDRPU formation.

Changes in Transcutaneous Oxygen Pressure in the Lower Limb Associated with the Use of Elastic Compression Stockings.

Objective: Elastic compression stockings are used to prevent venous thrombosis in postsurgical patients. However, they have been associated with skin complications, such as medical device-related pressure ulcers. This study aimed to assess the effect of elastic compression stockings on the skin tissue status of the lower limbs. Methods: Transcutaneous oxygen pressure (TcPO2) was measured in the anterior tibia and corresponding soft skin of healthy subjects before, during, and after continuous use of elastic stockings for 30 min. Results: Wearing elastic stockings significantly reduced TcPO2 in the skin of the anterior tibia, and removal of the stockings restored TcPO2 values. Both individuals who exercised regularly and men had lower TcPO2 at all measurement points than both individuals who did not exercise and women. Older subjects (50-60 years) had reduced TcPO2 in the sural region than younger ones (20-30 years). Conclusion: The use of elastic compression stockings caused an early decrease of TcPO2 in healthy subjects. Clinical patients were predicted to be at a high risk of wounding.

Preventive effects of skin protectants on the development of medical device-related pressure wounds in endoscopic sinonasal surgery

ObjectivesMedical device-related pressure ulcer (MDRPU) is a skin or subcutaneous tissue injury caused by medical devices. Skin protectants have been used to prevent MDRPU in other fields. In endoscopic sinonasal surgery (ESNS), rigid endoscopes and forceps can cause MDRPU; however, detailed investigations have not been conducted. This study aimed to investigate the frequency of MDRPU in ESNS and the preventive effects of skin protectants MethodsThirty-nine patients who received ESNS and consented to study participation were randomly assigned to the “protective agent” (n = 18) or “control” (n = 21) group. MDRPU presence around the nostril was evaluated for up to 7 days post-surgically based on physical findings and subjective symptoms. The occurrence ratio and severity of MDRPU were statistically compared between the groups to evaluate the efficacy of skin protective agents. ResultsStage 1 MDRPU, according to the National Pressure Ulcer Advisory Panel classification, was seen in 20.5% (8/39) of the patients, and no patient had more high-grade ulceration. On postoperative days 2 and 3, skin erythema was predominantly observed on the nasal floor, with a comparatively lower incidence in the protective agent group. Significant pain reduction was observed in the nostril's floor on postoperative days 2 and 3 in the protective agent group. ConclusionsMDRPU occurred with a relatively high frequency around the nostrils after ESNS. Protective agent use in the external nostrils was effective especially in reducing post-operative pain on the nasal floor, where tissue damage can easily occur due to device-related friction.

Risk assessment scale for pressure ulcers in pediatric patients: French translation, internal consistency, convergent validity, feasibility, and clinical utility of the Braden QD Scale

Pediatric patients are particularly vulnerable to pressure ulcers. Structured evaluation with a risk assessment tool is recommended in order to identify patients at risk. The Braden QD Scale integrates the risks of both immobility-related and medical device-related pressure ulcers in pediatric patients. To translate and pretest the Braden QD Scale into French (Swiss-French version), and to evaluate its consistency, convergent validity, feasibility, and clinical utility. Over five prevalence surveys, the Braden QD Scale was used on all hospitalized pediatric patients. Convergent validity and internal consistency were tested. A self-administered questionnaire on feasibility and clinical utility was completed by nurses. The translated version of the Braden QD Scale was pretested on 352 children. The prevalence surveys showed that 5.1% were at risk of developing pressure ulcers. Medical devices were present in 85.8% of cases. A Cronbach's alpha of 0.710 and a high convergent validity were measured. High scores of feasibility and clinical utility were found. This study suggests that the Swiss-French version of the Braden QD Scale is reliable, valid, feasible, and has clinical utility.

Barriers and facilitators to reporting medical device-related pressure ulcers: A qualitative exploration of international practice

BackgroundPressure ulcers are a complex healthcare issue. Hospital-acquired pressure ulcers are used as proxy measurements for the quality and safety of nursing care. Medical device-related pressure ulcers are mostly facility acquired, but their reporting has only recently been widely adopted. Consequently, we do not yet know what factors impact their reporting by registered nurses. ObjectivesTo identify and systematically report determinants of the practice of medical device-related pressure ulcers reporting using the Tailored Implementation for Chronic Diseases checklist. DesignDescriptive, explorative design using semi-structured interviews to explore barriers and facilitators to reporting medical device-related pressure ulcers. SettingWe undertook online, telephone, and face-to-face interviews with participants from 11 different countries. ParticipantsWe interviewed 17 participants who represented acute care (Adult, Paediatrics), academia, and industry. Eleven participants were healthcare professionals with more than 10 years' experience in wound care. MethodsThe interview recordings were transcribed and coded by the lead researcher. Data were analysed thematically using the codebook approach, and themes were developed inductively and deductively. ResultsParticipants identified determinants of practice which clustered around four domains of the Tailored Implementation for Chronic Diseases checklist i) individual health professional factors, ii) professional interactions, iii) incentives and resources, and iv) capacity for organisational change. Knowledge, attitudes, workload, time, staffing, and perception of consequences, including financial, were identified as the main barriers to reporting. Factors supporting the practice were education, openness, and teamwork. Device procurement could take on characteristics of a barrier or facilitator depending on the organisation. ConclusionsReporting medical device-related pressure ulcers has been adopted in healthcare institutions worldwide. Understanding what drives the reporting practice enables improvements in incident reporting, which consequently can lead to improvements in the quality of nursing care and patient safety.

Medical device related pressure ulcers in Jordan: Prevalence study among critically ill patients.

BackgroundMedical device‐related pressure ulcers are increasingly common in critical care units. These ulcers can be complicated due to the necessity of the device for diagnosis or treatment.PurposeTo determine the prevalence of and risk for medical device‐related pressure ulcers in critical care units in Jordan in addition to identifying the preventive measures for those ulcers as well as identifying the most frequently used medical devices that cause ulcers and to assess the relationships between prevention measures and developing ulcers.MethodsA cross‐sectional survey was used to assess ulcers among 318 patients who were elder than 18 years old. Data collection was based on an outline published by the European Pressure Ulcer Advisory Panel, Braden Scale, and an author‐developed specific checklist.ResultsThe prevalence rate of medical device‐related pressure ulcers was 38.1%. Most affected sites were sacrum and heel, and most affected were those with old age, being admitted to public hospitals, and with a prolonged hospital stay. About half of the patients (46.3%) had severe risk. Only 17% of the patients who were at risk got adequate preventive measures. Face masks, endotracheal tubes, pulse oximetry probes, and intravenous catheters were associated with almost half of the ulcers.ConclusionMedical device‐related pressure ulcers are threats to patient safety and quality of nursing care in hospitals, which require determining appropriate preventive measures. Key messages:Medical device‐related pressure ulcers are common among patients in critical care units, which raise the need to evaluate the prevalence of such type of ulcers in those patients.Three hundred and eighteen patients were investigated for the prevalence of medical device‐related pressure ulcers through a cross‐sectional survey.Patients in critical care units in Jordan had a high prevalence rate for medical device‐related pressure ulcers, which require the need to apply appropriate preventive measures.

Alternatives and preferences for materials in use for pressure ulcer prevention: An experiment-reinforced literature review.

Alleviation of localised, sustained tissue loads and microclimate management are the most critical performance criteria for materials in use for pressure ulcer prevention, such as in prophylactic dressings, padding or cushioning. These material performance criteria can be evaluated by calculating the extents of matching between the material stiffness (elastic modulus) and the thermal conductivity of the protective dressing, padding or cushioning with the corresponding properties of native skin, separately or in combination. Based on these bioengineering performance criteria, hydrocolloids, which are commonly used for prophylaxis of medical device-related pressure ulcers, exhibit poor stiffness matching with skin. In addition, there is remarkable variability in the modulus and thermal conductivity matching levels of different material types used for pressure ulcer prevention, however, it appears that among the materials tested, hydrogels provide the optimal matching with skin, followed by gels and silicone foams. The stiffness matching for hydrocolloids appears to be inferior even to that of gauze. This article provides quantitative performance criteria and metrics for these evaluations, and grades commonly used material types to biomechanically guide clinicians and industry with regards to the selection of dressings for pressure ulcer prevention, both due to bodyweight forces and as a result of applied medical devices.

Validation of a numerical model for the mechanical behavior of a continuous positive airway pressure mask

Finite Element models (FEM) are developed for the analysis of the contact pressures exerted by a Continuous Positive Airway Pressure (CPAP) mask applied to a dummy head. This is seen as a preliminary step in the analysis of the mechanical effects of CPAP masks applied to human faces, such as recently employed for the care of COVID-19 patients, or other purposes. These mechanical effects can range from negligible, in the case of correct positioning, sufficiently light tension in the headgear, correct mask design, etc., to the possible development of device-related pressure ulcers and/or dentofacial deformations, especially in children. The results of Finite Element analyses are compared, for their validation, with experimental ones. The numerical analysis tool appears able to predict, at an acceptable cost, both the intensity and the area distribution of the contact pressures, as well as the force-displacement relationship occurring in the headgear. This might help the design and the production of more effective and tolerable CPAP masks.

Evaluation of facial tissue stresses under medical devices post application of a cyanoacrylate liquid skin protectant: An integrated experimental-computational study.

Medical device‐related pressure ulcers (PUs) (injuries) are a subclass of PUs, associated with pressure and/or shear applied by a medical device onto the skin. Clinical application of a cyanoacrylate liquid skin protectant (CLSP) under the contours of skin‐contacting medical devices to shield an intact skin from the sustained mechanical loads that are applied by medical devices is a preventative option, but no computer modelling work has been reported to assess the biomechanical efficacy of such interventions. Here, we investigated the biomechanical protective effect of a polymerised cyanoacrylate coating using three‐dimensional, anatomically realistic finite element models of the ear with oxygen cannula and the mouth with endotracheal attachment device, informed by experimental studies. We have compared tissue stress exposures under the devices at these facial sites between conditions where the cyanoacrylate skin protectant has been applied or where the device was contacting the skin directly, without the shielding of the cyanoacrylate coating. The CLSP considerably reduced the skin stress concentration levels and overall tissue stress exposures under the aforementioned medical devices. This demonstrates strong biomechanical effectiveness of the studied cyanoacrylate‐based skin protectant in prevention of facial medical device‐related injuries at small, curved and thereby difficult to protect facial sites.

The aetiology of medical device-related pressure ulcers and how to prevent them.

This article provides an introduction to the aetiology of medical device-related pressure ulcers (MDRPUs), describes the vicious cycle that leads to these injuries and highlights bioengineering methodologies and findings that connect the aetiology to the clinical practice of preventing MDRPUs. Specifically, the vicious cycle of MDRPUs is triggered by the sustained tissue deformations induced by a skin-contacting device. The primary, deformation-inflicted cell damage leads to a secondary inflammatory-oedema-related damage and then to tertiary ischaemic damage. Each of these three factors contributes to cumulative cell death and tissue damage under and near the applied device. The damage therefore develops in an escalated manner, as a result of the added contributions of the above three factors. This phenomenon is exemplified through two common clinical scenarios. First, through the use of continuous positive airway pressure (CPAP) masks, which are being applied extensively in the current COVID-19 pandemic, and, second, through the use of doughnut-shaped head positioners, which are applied to surgical patients and sometimes to bedridden individuals who receive intensive care in a supine position. These two medical devices cause intense, localised mechanical loads in the facial skin and underlying tissues (CPAP mask) and at the occipital scalp (doughnut-shaped positioner), where the soft tissues cannot swell in response to the inflammatory oedema as, in both cases, the tissues are sandwiched between the device and the skull. Accordingly, the two device types result in characteristic MDRPUs that are avoidable through appropriate prophylactic interventions, that is, preventive dressings under the CPAP mask and replacement of the doughnut device by a soft, shape-conforming support aid to alleviate and disperse the localised soft tissue deformations. Hence, understanding the aetiology of MDRPUs targets and focuses effective clinical interventions.

Factors Associated with Medical Device Related Pressure Ulcer Caused by Ankle Foot Orthosis

Factors Associated with Medical Device Related Pressure Ulcer Caused by Ankle Foot Orthosis

What makes a hydrogel-based dressing advantageous for the prevention of medical device-related pressure ulcers.

The synergistic influences of geometrical, mechanical and thermal mismatches between a skin‐contacting medical device and the skin may cause tissue stress concentrations and sharp temperature gradients, both of which contribute to the risk for medical device‐related pressure ulcers. In this work, we developed an innovative, integrated experimental bioengineering approach encompassing mechanical stiffness, friction and thermal property studies for testing the biomechanical suitability of a hydrogel‐based dressing in prophylaxis of injuries caused by devices. We characterised the viscoelastic stress relaxation of the dressing and determined its long‐term elastic modulus. We further measured the coefficient of friction of the hydrogel‐based dressing at dressing‐device and skin‐dressing interfaces, using a tilting‐table tribometer. Lastly, we measured the thermal conductivity of the dressing, using a heat‐flow meter and infrared thermography‐based method. All measurements considered dry and moist conditions, the latter simulating skin perspiration effects. Our results revealed that the long‐term stiffness and the thermal conductivity of the hydrogel‐based dressing matched the corresponding properties of human skin for both dry and moist conditions. The dressing further demonstrated a relatively high coefficient of friction at its skin‐facing and device‐facing aspects, indicating minimal frictional sliding. All these properties make the above dressing advantageous for prevention of device‐related injuries.

Subcutaneously anchored securement for peripherally inserted central catheters: Immediate, early, and late complications.

An adequate stabilization of a vascular device is an important part of insertion bundles and is an effective strategy in reducing complications. Dislodgment has a relevant clinical impact and an increase in healthcare costs. We have retrospectively investigated the safety and efficacy of Subcutaneously Anchored Securement (SAS) for Peripherally Inserted Central Catheters (PICC) in cancer patients. We analyzed 639 patients who had a PICC inserted and secured with SAS, over the past 3 years (2018-2020). No immediate complications during SAS placement were reported. In the first 24-48 h, a slight local ecchymosis was reported in 24 cases with rapid spontaneous resolution. No cases of bleeding or hematoma of the exit site were reported. The total number of catheter days was 93078. Dislodgment occurred only in seven cases (1.1%). In 16 patients, the PICC was removed because of catheter-related bloodstream infection (CRBSI): the overall incidence of CRBSI was 0.17 per 1000 catheter days. Symptomatic venous thrombosis was documented in 12 patients (1.9%) and treated with low molecular weight heparin without PICC removal. We had no cases of irreversible lumen occlusion. In 17 patients, local discomfort-including device-related pressure ulcers and painful inflammation-was reported: these cases were treated without SAS removal or PICC removal. In this retrospective analysis, subcutaneously anchored securement of PICCs was a safe and effective strategy for reducing the risk of dislodgment.

Physiological measurements of facial skin response under personal protective equipment

Medical device-related pressure ulcers (MDRPUs) were traditionally associated with skin-contacting medical devices applied to patients, eventually causing tissue damage. The coronavirus-2019 pandemic has brought a new variant of MDRPUs: facial skin irritation or damage associated with extended use of protective personal equipment (PPE), e.g. facemasks and respirators. In this context, we report here a comprehensive experimental evaluation including facial contact forces, skin temperatures and sub-epidermal moisture (SEM) measurements pre/post-PPE usage, to determine how these physiological parameters change under the effects of surgical facemasks and KN95 respirators and whether such potential changes can explain the commonly reported skin irritation or damage. We found that a surgical mask is potentially less irritating to facial skin than the KN95 respirator, as it applies lower forces and facilitates faster return of facial temperatures to their basal levels. Further, we demonstrated that use of dressing cuts for padding under a KN95 respirator considerably reduced localized forces and did not worsen the thermal and SEM readings at the skin-device contact sites. This study provides a basis for improvement of PPE designs, as it describes physiological measurement methodologies for quantitative comparisons of the effects of different PPE types on facial skin status.

The mechanobiology theory of the development of medical device-related pressure ulcers revealed through a cell-scale computational modeling framework

Pressure ulcers are localized sites of tissue damage which form due to the continuous exposure of skin and underlying soft tissues to sustained mechanical loading, by bodyweight forces or because a body site is in prolonged contact with an interfacing object. The latter is the common cause for the specific sub-class of pressure ulcers termed ‘medical device-related pressure ulcers’, where the injury is known to have been caused by a medical device applied for a diagnostic or therapeutic purpose. Etiological research has established three key contributors to pressure ulcer formation, namely direct cell and tissue deformation, inflammatory edema and ischemic damage which are typically activated sequentially to fuel the injury spiral. Here, we visualize and analyze the above etiological mechanism using a new cell-scale modeling framework. Specifically, we consider here the deformation-inflicted and inflammatory contributors to the damage progression in a medical device-related pressure ulcer scenario, forming under a continuous positive airway pressure ventilation mask at the microarchitecture of the nasal bridge. We demonstrate the detrimental effects of exposure to high-level continuous external strains, which causes deformation-inflicted cell damage almost immediately. This in turn induces localized edema, which exacerbates the cell-scale mechanical loading state and thereby progresses cell damage further in a nonlinear, escalating pattern. The cell-scale quantitative description of the damage cascade provided here is important not only from a basic science perspective, but also for creating awareness among clinicians as well as industry and regulators with regards to the need for improving the design of skin-contacting medical devices.

Preventing and managing device-related pressure ulcers in oncology.

There is growing evidence that medical device-related pressure ulcers (MDRPUs) are an increasing healthcare concern in all aspects of care. It is especially important to develop an individualised care plan for people at the end of life to prevent pressure ulceration and to treat this if it occurs. Tissue viability nurses have a responsibility to review and assess new prophylactic devices and dressings, to ensure a high standard of care is provided. This article describes the use of a soft silicone dressing, Kliniderm foam silicone lite, in combination with best practice, to prevent MDRPUs in the oncology setting. Three case studies show that the dressing helped avoid the occurrence of ulceration on the ears and nose in patients receiving oxygen through a nasal cannula.
