Determination of medical device-related pressure injury in COVID-19 patients: A prospective descriptive study

BackgroundCOVID-19 patients are at risk for the development of pressure injuries (PI).AimThe aim of this study was to determine the incidence of medical device-related pressure injury (MDRPI) in patients treated in the COVID-19 Intensive Care Unit (ICU)s.MethodsThe sample of the study consisted of 132 patients, and each with a maximum follow-up of 7 days. Data were collected in the COVID-19 ICU of a university hospital between January and May 2021 by using a Patient Characteristics Form, the MDRPI Follow-up Form, the Braden Pressure Ulcer Risk Assessment Scale, and the Pressure Ulcer Staging Form.ResultsOf the patients, 59.1% (n = 78) developed at least one MDRPI. MRDPI was observed in those with a mean age of 65.45 ± 2.462 years who were invasively ventilated (51.3%), enterally fed (46.2%), placed in the prone position (78.2%), and had a Braden score ≤12 (50%). The most common medical devices that caused MDRPIs included endotracheal tube (ET) (31.2% n = 44), non-invasive mechanical ventilation (NIVM) (23.4% n = 33), nasal high-flow (11.3% n = 16), nasogastric tube (10.6% n = 15), the ET connection (8.5% n = 12), respectively. The most common sites for pressure injuries were the nose (28.8% n = 34), mouth (25.8% n = 34), ear (12.9% n = 17), lip (9.1% n = 12), and cheek (8.3% n = 11). The most common gradings of MDRPIs were stage 2 (28.8% n = 38), stage 1 (19.7% n = 26), stage 3 (9.1% n = 12) mucous membrane injuries (12.9% n = 17) and suspected deep tissue injuries (9.1% n = 12), respectively. The time to PI was 3 days (25.7% n = 36).ConclusionsMDRPI was common among COVID-19 patients. It was found that the most common cause of pressure injury was ventilators, and PI developed in the mouth and lip sites most frequently in patients in prone position, stage 2 and suspected deep tissue damage was the most common grade. It is important to evaluate the skin in contact with medical devices in COVID-19 patients and to take the necessary interventions to prevent PI.     

Risk prediction models for the development of oral-mucosal pressure injuries in intubated patients in intensive care units: A prospective observational study

PurposeOral-mucosal pressure injury (PI) is the most commonly encountered medical device-related PIs. This study was performed to identify risk factors and construct a risk prediction model for oral-mucosal PI development in intubated patients in the intensive care unit.MethodsThe study design was prospective, observational with medical record review. The inclusion criteria stipulated that 1) participants should be > 18 years of age, 2) there should be ETT use with holding methods including adhesive tape, gauze tying, and commercial devices. Data of 194 patient-days were analysed. The identification and validation of risk model development was performed using SPSS and the SciKit learn platform.ResultsThe risk prediction logistic models were composed of three factors (bite-block/airway, commercial ETT holder, and corticosteroid use) for lower oral-mucosal PI development and four factors (commercial ETT holder, vasopressor use, haematocrit, and serum albumin level) for upper oral-mucosal PI development among 10 significant input variables. The sensitivity and specificity for lower oral-mucosal PI development were 85.2% and 76.0%, respectively, and those for upper oral-mucosal PI development were 60.0% and 89.1%, respectively. Based on the results of the machine learning, the upper oral-mucosal PI development model had an accuracy of 79%, F1 score of 88%, precision of 86%, and recall of 91%.ConclusionsThe development of lower oral-mucosal PIs is affected by immobility-related factors and corticosteroid use, and that of upper oral-mucosal PIs by undernutrition-related factors and ETT holder use. The high sensitivities of the two logit models comprise important minimum data for positively predicting oral-mucosal PIs.     

The effect of sub-epidermal moisture on pressure injury prevention strategies and incidence of pressure injuries: A feasibility pilot randomised controlled trial

AimSub-epidermal moisture scanning (SEMS) is a novel point-of-care technology that measures localised oedema and detects early tissue damage that may develop into a pressure injury (PI). It provides objective data that may assist PI prevention (PIP) decision making. This study aimed to determine the feasibility of undertaking a definitive randomised controlled trial (RCT) to test the effectiveness of SEMS.Materials and methodsThis pilot RCT recruited medical and surgical patients at risk of developing a PI in one Australian hospital. All participants received routine PIP care and daily visual skin assessment to determine the presence of a PI. The intervention group also received daily SEMS. Clinical staff were told if the sub-epidermal moisture (SEM) value was abnormal but were not given advice for PIP. Blinding of patients, care staff and outcome assessors was not practical. Feasibility outcomes included recruitment, retention, intervention fidelity, and patient outcomes.ResultsOf 1185 patients screened prior to eligibility, 950 were excluded (80%); 235 were then assessed for eligibility and 160 met the inclusion criteria (68.1%); 100 were recruited (70.0%) and randomised and 99 completed the trial (intervention n = 50; control n = 49) with one person withdrawn due to inappropriate recruitment (100% retention). Of the 657 expected SEMS observations, 598 were completed (91% intervention fidelity). Only 34 of 454 (7.4%) patient outcome data points were missing.ConclusionsMost feasibility criteria were met, indicating a definitive trial to assess the effectiveness of SEMS in a medical-surgical patient population is realistic. However, recruitment may be resource intensive and require specific strategies.     

Knowledge of pressure injury in medical and surgical nurses in a tertiary level hospital: A cross-sectional study

BackgroundNurses play a vital role in pressure injury prevention (PIP) but require foundational knowledge to ensure appropriate PIP strategies are enacted.AimsTo describe and compare medical and surgical nurses’ knowledge of pressure injury (PI) in a tertiary level hospital in China, and to identify predictors of PI knowledge among these groups.DesignA cross-sectional survey was conducted between June and December 2020.MethodsRegistered nurses from nine medical and fifteen surgical wards in a tertiary hospital were invited. The survey was composed of two parts; demographic and professional characteristics; and the Chinese translated version of the Pressure Ulcer Knowledge Assessment Tool 2.0 (PUKAT 2.0) where the total score ranged from 0 to 25; higher scores imply more knowledge. Medical and surgical nurses' knowledge test scores were compared using independent t-test. Multiple linear regression analysis was used to determine factors predictive of nurses’ knowledge.ResultsIn total, 423 nurses from 24 wards participated the study and 404 nurses (95.5%) completed the knowledge test (Surgical n = 236, 58.4%; Medical n = 168, 41.6%). The PUKAT 2.0 mean score was 11.6 ± 3.0 (Surgical 12.2 ± 3.0; Medical 10.7 ± 2.8) with 335 (82.9%) nurses scoring <60%. Multiple linear regression showed working in surgical wards, nurse-in-charge position and previous PI training were significant predictors of knowledge scores.ConclusionKnowledge is a precursor to safe practice. Nurses demonstrated poor knowledge of PIP. Pressure injury related education may help improve nurses' knowledge but the extent to which it is used in place and impacts patients’ outcome requires more investigation.     

Risk factors for the development and evolution of deep tissue injuries: A systematic review

AimsThe aim of this systematic review is to identify the current epidemiological evidence indicating the unique risk factors for deep tissue injury (DTI) compared to grade I-IV pressure injury (PI), the proportion of DTI which evolve rather than resolve and the anatomical distribution of DTI.MethodsA systematic literature search was undertaken using the MEDLINE and CINAHL Plus databases using the search terms ‘Deep tissue injury OR DTI [Title/abstract]’. A google scholar search was also conducted in addition to hand searches of relevant journals, websites and books which were identified from reference lists in retrieved articles. Only peer-reviewed English language articles published 2009–2021 were included, with full text available online.ResultsThe final qualitative analysis included nine articles. These included n = 4 retrospective studies, n = 4 prospective studies and n = 1 animal study.ConclusionThe literature indicates that the majority of DTI occur at the heel and sacrum although in paediatric patients they are mainly associated with medical devices. Most DTI are reported to resolve, with between 9.3 and 27% deteriorating to full thickness tissue loss.Risk factors unique to DTI appear to include anaemia, vasopressor use, haemodialysis and nicotine use although it is unclear if these factors are unique to DTI or are shared with grade I-IV PI. Factors associated with deterioration include cooler skin measured using infrared thermography and negative capillary refill. With 100% of DTI showing positive capillary refill in one study resolving without tissue loss (p = 0.02) suggesting this may be an effective prognostic indicator.More prospective studies are required focusing on establishing causal links between risk factors identified in earlier retrospective studies. Ideally these should use statistically powered samples and sufficient follow up periods allowing DTI outcomes to be reached. Further work is also needed to establish reliable diagnostic criteria for DTI in addition to more studies in the paediatric population.     

Pressure injury prevention: Knowledge and attitude and their predictors in Indonesian nurses working in hospital settings

AimNurses' knowledge and attitude are critical for pressure injury (PI) prevention. However, to date, there has been little research carried out on the knowledge and attitude of Indonesian nurses regarding PI prevention in hospital settings, and no study has investigated the predictors of knowledge and attitude of Indonesian nurses regarding PI prevention. This study therefore aims to investigate knowledge and attitude, and to identify the predictors of knowledge and attitude regarding PI prevention among Indonesian nurses in hospital settings.MethodsA cross-sectional study was conducted between 1st November 2021 and 5th March 2022. A total of 563 nurses from three general hospitals in Central Java Province participated. The Pressure Ulcer Knowledge Assessment Tool 2.0 and the Attitude Pressure Ulcer Prevention questionnaires were used. A multiple linear regression analysis was used to determine the predictors of nurses' knowledge and attitude regarding PI prevention.ResultsThe percentage of correct answers was 35.02%, indicating poor knowledge, while the percentage of nurses' attitudes was 75.46%, indicating a satisfactory attitude. The predictors of knowledge of PI prevention were found to be age (β = -0.127, p = 0.025), level of education (β = 0.153, p = 0.001) and income (β = 0.107, p = 0.021), while the predictors of attitude toward PI prevention were level of education (β = 0.101, p = 0.020) and professional position (β = 0.093, p = 0.033).ConclusionThis is the first study to identify the predictors of attitude and knowledge regarding PI prevention in Indonesian nurses in a hospital setting. The results indicate a need for appropriate educational training based on the predictors to be given to Indonesian nurses working in hospital settings to increase their knowledge of PI prevention.     

Influencing factors of pressure injury healing in an acute care setting: A retrospective cohort study

AimThis study aimed to investigate the factors that influence healing during acute care hospitalization by examining the differences in pressure injury (PI) status between admission and discharge.Material and methodsA total of 371 patients who met the study's inclusion criteria were divided into two groups (aggravated or improved) based on the PI status observed at admission and discharge. We used bivariate analyses to compare demographics and clinical factors associated with wound severity and aggravation/improvement of wound condition. Using multiple logistic regression, we identified and examined independent predictors for significant association with aggravation/improvement of the wound status.ResultsThe prevalence rate of PI at acute hospital admission was 12.5%. By the time of discharge, only 5.4% of PI patients had improved PI, whereas 12.6% had aggravated PI. The significant aggravating factors of PI during acute care hospitalization were the patient's consciousness level, use of foley catheter, creatinine level, and Braden Scale scores (p < .05). Residential place prior to admission were found to be associated with the healing.ConclusionsNurses providing prophylactic management require close attention to patients who are admitted from long-term facilities to prevent aggravation of PI during acute care hospitalization.     

How the COVID-19 pandemic influences the prevalence of pressure injuries in the Czech Republic: A nationwide analysis of a health registry in 2020

BackgroundCOVID-19 significantly influences the overall patient status and, in severe symptomatology, the ability to move and the low oxygenation of the tissue for the ventilated patient in Intensive Care Units (ICU). There is a higher risk for Pressure injuries (PIs) development.ObjectivesThe nationwide analyses of the National health register aimed to compare the prevalence of PIs reported before the pandemic COVID-19 started and during the pandemic in 2020.MethodA retrospective, nationwide cross-sectional analysis of data regarding the STROBE checklist collected by the National Health Information System (NHIS), focusing on the PIs reporting based on the International Classification of Diseases (ICD-10) diagnoses L89.0-L89.9 for PIs in 2020. The data from the pandemic period of COVID-19 in 2020 were compared to the prevalence of PI cases in the period 2010–2019 in the Czech Republic in all hospitalized patients.ResultsThe total number of admissions for L89 in 2020 was 14,441, of which 1509 (10.4%) also had COVID-19. In the ICU were 4386 admissions, 12.1% of which also had COVID-19. A higher proportion of PIs is observed in patients hospitalized with COVID-19 than in patients without COVID-19 (2.62% vs 0.81%, respectively 1.05% vs 0.46% when standardized to the 2013 ESP = European Standard Population). In patients hospitalized in ICU, 3.68% with COVID-19 had PIs vs 1.42% without COVID-19 had PIs (1.97% vs 0.81% using the 2013 ESP).ConclusionThe national health registers analyses have proven that the prevalence of PIs was higher among patients hospitalized with the SARS-CoV-2 infection.     

Determination of the effect of prophylactic dressing on the prevention of skin injuries associated with personal protective equipments in health care workers during COVID-19 pandemic

AimThe present study was carried out as a comparative observational study in order to determine the effect of prophylactic dressing on the prevention of skin injuries due to the use of personal protective equipment (PPE) in health care workers (HCWs) working with COVID-19 patients. In addition, the effect of nasal strip on the prevention of discomfort in breathing with mask was also investigated.Materials and methodsThe present study was carried out with 48 HCWs (Control Group-CG, n = 20; Experimental Group 1-EG1, n = 20; Experimental Group 2-EG2, n = 8) who use PPE on the face region and work with COVID-19 patients. Data was collected with Data Collection Form developed by researchers. In participants in CG, normal procedures of the institution in using PPE were followed. In EG1, prophylactic dressing was used on risky areas on the face. In EG2, nasal strip sticky on one side was used in addition to prophylactic dressing. The evaluation of the facial skin was made once a day by a researcher with expertise in wound management.ResultsGroups were similar in terms of demographic characteristics of participants. Overall rate of skin injuries associated with PPE use was 47.9%. Skin injuries developed in all participants in CG (n = 20), and in two and one participants in EG1 and EG2 respectively, with significant difference between groups. The most common skin injuries were Stage 1 pressure injury (29.2%), blanchable erythema of intact skin (27.1%) and itching (18.8%). No participant in EG2 reported discomfort in breathing (n = 8). Significant difference was found between groups in favor of EG2 in terms of experiencing discomfort in breathing (p < 0.001).ConclusionsIn the present study, it was established that using prophylactic dressing under PPE prevents skin injuries on the facial skin and using nasal strip prevents discomfort in breathing with mask. In view of these results, it was recommended that prophylactic dressing should be used under PPE.     

Remote assessment of surgical site infection (SSI) using patient-taken wound images: Development and evaluation of a method for research and routine practice

Background/aimClinical assessment of wounds for surgical site infection (SSI) after hospital discharge is challenging and resource intensive. Remote assessment using digital images may be feasible and expedite SSI diagnosis. Acceptable and accurate methods for this process are needed. This study developed and evaluated the feasibility, acceptability and usability of a method for patients to capture standardised wound images for remote wound assessment to detect SSI.Materials and methodsThe work was conducted in two phases. Phase I involved: i) a review of literature to identify key components of photography relevant to taking wound images, ii) development of wound photography instructions for patients and a secure process for transmission of images using electronic survey software and iii) pre-testing of the photography instructions and processing method with a sample of 16 patients using cognitive interviews and observations. Phase II involved a prospective cohort study of 89 patients to evaluate the feasibility, acceptability and usability of the remote method following discharge from hospital after surgery. Quality of the images was assessed by three independent clinical reviewers.ResultsSome 21 key components for photographing wounds were identified from 11 documents. Of these, 16 were relevant to include in instructions for patients to photograph their wounds. Pre-testing and subsequent iterations improved understanding and ease of use of the instructions and the process for transmitting images. Fifty-two of 89 (58.4%) patients testing the method remotely took an image of their wound(s) and 46/52 (88.5%) successfully transmitted images. When it was possible to ascertain a reason for not taking/transmitting images, this was primarily health problems (n = 7) or lack of time/poor engagement with the study (n = 4) rather than problems relating to technology/competency (n = 2) or practical issues relating to the wound itself (n = 2). Eighty-seven (85.3%) of the 102 images received were evaluated to be of high quality and sufficient to remotely assess SSI by at least two independent reviewers.ConclusionA simple, standardised and acceptable method for patients to take and transmit wound images suitable for remote assessment of SSI has been developed and tested and is now available for use in routine clinical care and research.     

Using process-oriented groups reflections with health care providers to improve childbirth care in the Democratic Republic of Congo – An implementation study

ObjectiveThe ability to systematically reflect on care during labour and birth needs to be developed among health care providers. This study investigates the experiences of health care providers who have participated in process-oriented group reflections. The activity of group reflections was one of the three pillars of a training intervention seeking to implement evidence-based care routines during labour and birth that could contribute to reduced mortality and improved maternal and newborn health in the Democratic Republic of Congo (DRC).MethodsUsing a qualitative approach, we interviewed 131 health care providers, in focus groups (n = 19) and individually (n = 2). Analysis of transcribed interviews was conducted using qualitative content analysis according to Elo and Kyngäs.ResultsGroup reflections added essential knowledge to the other components of the three-pillar training intervention. Through sharing and analysing care situations health care providers got increased self-awareness, tools to achieve structured and safe care routines, and to practice teamworking.ConclusionUsing a structured model of process-oriented group reflection for health care providers on care during labour and birth proved to be a vital aspect of the training intervention, as it added knowledge to the skills gained through theoretical and simulation-based education. The three-pillar training intervention improved care routines that supported healthy births and management of complications. We recommend that structured and secure group reflections be included in similar training activities in the DRC and elsewhere, and assessed in further studies.     

Sacral interface pressure can be alleviated by repositioning with a small-angle change using an automated bed in patients with spinal cord injury

Aim of the studyThis study aimed to compare interface pressure and total contact area of the sacral region in different positions, including small-angle changes, in patients with spinal cord injury (SCI). Furthermore, we analyzed the clinical factors influencing pressure to identify the pressure injury (PI) high-risk group.Materials and methodsAn intervention was conducted for patients with paraplegia (n = 30) with SCI. In the first and second trials, interface pressure and total contact area of the sacral region were recorded from large- and small-angled positions using the automatic repositioning bed, which can change the angle of the back, lateral tilt, and knee.ResultsPositions with back raised ≥45° showed significantly higher pressure on the sacrum than most other positions. The pressure and contact area differences were statistically insignificant for combinations of small-angled changes <30°.Additionally, the duration of injury (β = 0.51, p = 0.010) and neurological level of injury (NLI) (β = −0.47, p = 0.020) were significant independent predictors of average pressure. Similarly, the duration of injury (β = 0.64, p = 0.001), the Korean version of the spinal cord independence measure-III (β = −0.52, p = 0.017), and body mass index (BMI; β = −0.34, p = 0.041) were significant independent predictors of peak pressure.ConclusionsFor repositioning, combinations of small-angle changes <30° effectively reduce pressure on the sacral region in patients with SCI. Lower BMI, longer duration of injury, lower functioning score, and NLI ≥ T7 are predictors of high sacral pressures, which increase the risk for PI. Therefore, patients with these predictors require strict management.     

The effectiveness of a hydrocolloid crusting method versus standard care in the treatment of incontinence-associated dermatitis among adult patients in an acute care setting: A randomised controlled trial

IntroductionIncontinence-associated dermatitis (IAD) is a type of irritant contact dermatitis due to prolonged exposure of the skin to moisture induced by urine or/and faeces. The main principles when treating IAD involves protecting the skin from further exposure to irritants, establishing a healing environment, and eradicating skin infections. This study aimed to evaluate the effectiveness of the hydrocolloid crusting method (HCM) versus the standard care method (SCM) in treating IAD.MethodA randomised controlled trial was conducted in an acute tertiary hospital in Singapore between August 2019 to September 2021. Using computer-generated numbers, patients were randomised into either HCM or SCM treatment groups. HCM treatment involved cleansing the affected area with a pH-neutral non-rinse moisturising cleanser, and the application of alternate layers of hydrocolloid powder, and non-sting film barrier spray (repeated three times during each use). Patients in the SCM treatment group received the same cleanser followed by a 30% zinc oxide barrier cream. IAD was assessed daily for up to seven days by the wound care nurses using the IAD severity tool. The primary outcome of the study was the mean difference in IAD score per day between both methods.ResultsForty-four patients were eligible and recruited (22 in HCM; 22 in SCM). Patients in both groups were comparable in age and gender. IAD Category 2 was more predominant in both methods. The most common location of IAD was at the perianal skin and diarrhea related to gastroenteritis was the most prevalent cause of IAD. More patients in the SCM group (n = 12; 54.5%) had their IAD healed within seven days compared to HCM, (n = 7; 31.8%) group. However, the average decrease in IAD scores per day for both methods were found to be similar.ConclusionHCM can be considered as a treatment of IAD along with the use of SCM. A skin care regimen should include effective cleansing, skin protection, and moisturization in IAD management.     

Right siting of complex acute wound management---preliminary study of teleconsultation wound services between acute and primary care in Singapore

This study aimed to provide preliminary evidence on feasibility of the inaugural use of teleconsultation between acute hospitals and primary care for acute wound management in Singapore. Post-surgical patients with carbuncle wounds, perianal abscess wounds or surgical abdominal dehiscence wounds were recruited from an acute hospital. Instead of receiving their follow up care at the acute care tertiary hospital, patients were given the option to receive their care at primary care facilities instead, supported by teleconsultation wound services provided by wound care nurses from the hospital. The following outcome measures were collected: number of care sessions required (until wound healed), readmissions or referrals back to hospital, cost (patient's and healthcare provider's perspective), patients' and nurses' satisfaction.In total, 18 patients were recruited and completed the study (teleconsult group = 5; tertiary care clinic group = 13). The mean age (SD) of patients were 63.2 (SD 11.5) years old in the teleconsult group and 47.9 years old (SD 11.5) in the tertiary care clinic group. There were 7 female (54%), and 6 male (46%) in the tertiary care clinic group whereas teleconsult group consisted of male only (n = 5). Most had carbuncle wounds (teleconsult group: n = 4; 80%); tertiary care clinic group: (n = 10; 77%). For patients with carbuncle wounds, the average number of care sessions required were 21 and 33 for the tertiary care clinic and teleconsult respectively. None of the patients in the teleconsult group were referred back to the tertiary care hospital. All 16 nurses (n = 6 from acute care hospital, n = 10 from polyclinics) who participated in the feedback survey cited convenience, ease of tracking wound sizes, and closer collaboration between the acute care and primary care nurses as advantages of the service. Wound teleconsultation is feasible and potentially cost savings for patients with acute complex wounds.
