Pressure ulcers during the COVID-19 pandemic in intensive care:A multicenter cohort study.

AIM: The objective of the present study is twofold: to describe the prevalence and incidence of pressure ulcers (PUs) among ICU patients during the COVID-19 pandemic, and to identify the risk factors associated with the development of PUs in this cohort of ICU patients. MATERIALS AND METHODS: Retrospective cohort study of adult critical care patients admitted in two general ICUs of two different countries (Sweden and Portugal) between March 1st, 2020, and April 30th, 2021, through the analysis of the electronic health record database. The prevalence and incidence were calculated, and a multivariate logistic-regression model was used to calculate odds ratios (ORs), of possible risk factors of PU development. RESULTS: The sample consisted of 1717 patients. The overall prevalence of PU was 15.3 %, and the incidence of ICU-acquired PUs was 14.1 %. Most of the pressure ulcers documented in this study were at the anterior part of the body (45.35 %) and regarding classification, Category 2 (38.40 %) and Category 3 (22.71 %) pressure ulcers together accounted for over fifty percent of the cases recorded. In the multivariate logistic regression model for PU, age, having COVID-19 (OR = 1.58, 95 % CI: 1.20-2.09), use of mechanical ventilation (OR = 1.49, 95 % CI: 1.13 = 1.97), use of vasopressors (OR = 1.31, 95 % CI: 1.00-1.70), having a Braden risk score ≤16 at admission (OR = 1.63; 95 % CI: 1.04-2.56), and length of stay (LOS) (OR = 1.43, 95 % CI 1.03-2.00 if LOS 90-260 h, OR = 2.34, 95 % CI: 1.63-3.35 if LOS >260 h) were associated with the likelihood of developing an ICU-acquired PUs. CONCLUSION: When adjusted for covariates patients with COVID-19 had a higher risk for PU development during the ICU stay compared to patients without COVID-19. Health care personnel in ICU may consider incorporating COVID-19, age, use of mechanical ventilation, vasopressors and estimated LOS in addition to a comprehensive risk assessment including both a risk score and clinical assessment.

Pressure ulcer prevalence and prevention interventions - A ten-year nationwide survey in Sweden.

The aim of this study was to describe pressure ulcer prevalence and prevention interventions in hospital care in Sweden based on nationwide surveys conducted over a 10-year period. All Swedish hospitals were invited to participate in annual pressure ulcer prevalence surveys during the period 2011-2020. The data collection protocols included gender, age, skin assessment, risk assessment, and preventive interventions. In total, more than 130,000 patients were included in the ten prevalence surveys. The prevalence of pressure ulcers in Swedish hospital patients decreased significantly from 17.0 %to 11.4% between 2011 and 2020 and hospital-acquired pressure ulcers decreased from 8.1% to 6.4% between 2018 and 2020. There was no significant decline in medicaldevice-related pressure ulcers during the same period. The proportion of patients who were risk and skin assessed increased, as did the use of pressure-reducing mattresses, sliding sheets, heel protection, and nrepositioning plans. This study shows that the implementation of a national patient safety program has had an impact on the nationwide prevalence of pressure ulcers in hospital care and the occurrence of prevention strategies. However, one in ten patients in Swedish hospitals still suffers from pressure ulcers. Further improvements can be made.

Enabling patient safety awareness using the Green Cross method: A qualitative description of users' experience.

AIM: The Green Cross method was developed to support healthcare staff in daily patient safety work. The aim of this study was to describe users' experiences of the method when working with patient safety and their views on the core elements. BACKGROUND: Patient safety systems need to be user-friendly to facilitate learning from adverse events. The Green Cross method is described as a simple visual method to recognise risks and preventable adverse events (PAEs) in real time. There are no previous studies describing users' experiences of the Green Cross method. DESIGN: A qualitative descriptive design. METHODS: 32 healthcare workers and managers from different specialties in a Swedish hospital were interviewed, from May-September 2018 about their experiences of the Green Cross method; either individually or as part of a group. The interviews were analysed using thematic analysis. The study follows the COREQ guidelines for qualitative data. RESULTS: Participants associated the Green Cross method with patient safety, but no core elements of the method were identified. Instead, the opportunity to be engaged in patient safety work in a systematic way was underlined by all study participants. Highlighted key areas were the simplicity and the systematic framework of the method along with a need of distinct leadership. The daily meetings promoted trust and dialogue and developed the patient safety mindset. Daily meetings, together with the visualisation of the cross, were emphasised as important by users who otherwise had limited knowledge of the entire method. CONCLUSION: This study offers valuable information that can help deepen the understanding of how the method specifically supports patient safety work. RELEVANCE TO CLINICAL PRACTICE: Healthcare workers are expected to report patient safety issues. This study presents user-friendly aspects of the method as well as limitations, relevant for present and future users.

Healthcare staff's views on the patients' prerequisites to be co-creator in preventing healthcare-associated infections.

BACKGROUND: Every year, patients are affected by suffering and death caused by adverse events in connection with health care and the most common adverse events are healthcare-associated infections (HAI). The Swedish Patient Act from 2015 strengthens the patient's position in health care; however, there is lack of knowledge of how healthcare staff experience the possibilities to make the patient involved in the preventive work of HAI. AIM: To describe healthcare professionals' views on the patient's prerequisites to be co-creator in preventing HAI in connection with hospital care. METHOD: This study had a qualitative descriptive design with semi-structured individual interviews. Qualitative inductive content analysis was used to analyse the transcribed interview data. The study setting was a hospital in Sweden in 2015. Interviews were carried out among six healthcare professionals. RESULTS: In the analysis, 5 themes and 14 categories were identified in three different domains: Organisation, Healthcare staff and Patient. The result indicates an obstacle in each domain for the patient to become co-creator in preventing HAI. In Organisation domain, a lack of organizational structure such as elaborated working methods to involve the patient was pointed out. In the domain Healthcare staff, it showed that the professionals allocate the responsibility of preventing HAI to the patient but only if they had to or if they trusted the patient. In the Patient domain, the result states that the patient was perceived as passive; they did not take own initiatives to get involved. CONCLUSION: The patient has an important role in successful HAI prevention work and should be considered as an obvious co-creator. Nevertheless, this study shows that neither organisation nor healthcare staff are sufficiently prepared for this. The organisation must make an anchored, structured and systematic work centred on the patient's needs and give more support both to healthcare professionals and patients.

Swedish translation and validation of the international skin tear advisory panel skin tear classification system.

The aims of this study were to translate the International Skin Tear Advisory Panel (ISTAP) classification system for skin tears into Swedish and to validate the translated system. The research process consisted of two phases. Phase I involved the translation of the classification system, using the forward-back translation method, and a consensus survey. The survey dictated that the best Swedish translation for "skin tear" was "hudfliksskada." In Phase 2, the classification system was validated by health care professionals attending a wound care conference held in the spring of 2017 in Sweden. Thirty photographs representing three types of skin tear were presented to participants in random order. Participants were directed to classify the skin tear types in a data collection sheet. The results indicated a moderate level of agreement on classification of skin tears by type. Achieving moderate agreement for the ISTAP skin tear tool is an important milestone as it demonstrates the validity and reliability of the tool. Skin tear classification typing is a complex skill that requires training and time to develop. More education is required for all health care specialists on the classification of skin tears.

Blood flow responses over sacrum in nursing home residents during one hour bed rest.

OBJECTIVES: To describe individual BF responses in a nursing home resident population for one-hour periods of bed rest. METHODS: BF was measured for one hour over the sacrum in 0° supine position and 30° supine tilt position in 25 individuals aged 65 y or older while lying on a pressure-redistributing mattress. Measurements were made at three tissue depths (1, 2, and 10 mm) using the noninvasive optical techniques, LDF and PPG. RESULTS: Eleven participants had a PIV response at 1 mm depth in both positions and seven participants had a lack of this response at this depth and positions. The BF response at 1 mm depth appeared immediately and remained over, or below, baseline for the entire 60 min of loading in both positions. These BF patterns were also seen in deeper tissue layers. CONCLUSIONS: The cutaneous BF response among the nursing home residents was distinct, appeared early, and remained during the one hour of loading.

An investigation of the ability to produce a defined 'target pressure' using the PressCise compression bandage.

Compression therapy is the cornerstone in the prevention and treatment of leg ulcers related to chronic venous insufficiency. The application of optimal high pressure is essential for a successful outcome, but the literature has reported difficulty applying the intended pressure, even among highly skilled nurses. The PressCise bandage has a novel design, with both longitudinal and horizontal reference points for correct application. In the current experimental study, the results for the general linear model, where the data set is treated optimally, showed that all 95% confidence intervals of the expected values for pressure were, at most, 5 mmHg from the target value of 50 mmHg, independent of the position on the leg and the state of activity. Moreover, even nurses with limited experience were consistently able to reach the targeted pressure goal. Future studies are needed to determine how well the bandage works on legs of different shapes, the optimal way of using the bandage (day only or both day and night) and whether the bandage should be combined with an outer bandage layer. In addition, special attention should be paid to subjective patient experiences in relation to the treatment as pain, discomfort and bulk are factors that can compromise patients' willingness to adhere to the treatment protocol and thereby prolong the healing process.

Nursing staff induced repositionings and immobile patients' spontaneous movements in nursing care.

The aim of this study was to investigate nursing staff induced repositionings and the patients' spontaneous movements during the day and night among older immobile patients in nursing care. Furthermore, the aim was to identify factors associated with the nursing staff induced repositionings and the patients' spontaneous movement frequency. An observational cross-sectional design was used. Spontaneous movements among patients (n = 52) were registered continuously using the MovinSense monitoring system. The nursing staff documented each time they repositioned the patient. Patients spontaneous movements were compared with nursing staff induced repositionings. There were large variations in the patients' spontaneous repositioning frequency during both days and nights, which shows that, although immobilised, some patients frequently reposition themselves. Analgesics were positively related to the movement frequency and psycholeptics were negatively related. The nursing staff more often repositioned the patients who were assessed as high risk than those assessed as low risk, but the patients' spontaneous movement frequency was not correlated to the risk score. This may be important when planning repositioning schedules. A monitoring system may be useful in decision making with regard to planning repositioning and positions used in the prevention of pressure ulcers among elderly immobile patients.

Pressure-induced vasodilation and reactive hyperemia at different depths in sacral tissue under clinically relevant conditions.

OBJECTIVE: To characterize PIV and RH at different sacral tissue depths in different populations under clinically relevant pressure exposure. METHODS: Forty-two subjects (<65 years), 38 subjects (≥65 years), and 35 patients (≥65 years) participated. Interface pressure, skin temperature, and blood flow at tissue depths of 1, 2, and 10 mm (using LDF and PPG) were measured in the sacral tissue before, during, and after load in a supine position. RESULTS: Pressure-induced vasodilation and RH were observed at three tissue depths. At 10 mm depth, the proportion of subjects with a lack of PIV was higher compared to superficial depths. The patients had higher interface pressure during load than the healthy individuals, but there were no significant differences in blood flow. Twenty-nine subjects in all three study groups were identified with a lack of PIV and RH. CONCLUSIONS: Pressure-induced vasodilation and RH can be observed at different tissue depths. A lack of these responses was found in healthy individuals as well as in patients indicating an innate susceptibility in some individuals, and are potential important factors to evaluate in order to better understand the etiology of pressure ulcers.

Predictive validity of 4 risk assessment scales for prediction of pressure ulcer development in a hospital setting.

OBJECTIVES: The aims of this study were to examine and compare the predictive validity of 4 risk assessment scales used for the prediction of pressure ulcer (PrU) development and to identify risk factors. DESIGN: Cross-sectional descriptive study. SETTING: A general hospital in Sweden. PARTICIPANTS: Patients (all aged ≥18 years) admitted to medical, surgical, orthopedic, oncology, and rehabilitation wards. Of 412 patients available, a total of 346 patients participated in the study. METHOD: Data were collected using the Swedish version of the European Pressure Ulcer Advisory Panel minimum data set as well as the Norton, Modified Norton, Braden, and Risk Assessment Pressure Sore (Ulcer) (RAPS) scales. The predictive validity was estimated by measuring sensitivity, specificity, positive predictive value, and negative predictive value. Multiple logistic regression analysis was used to determine risk factors associated with PrUs. RESULTS: The RAPS scale reached best balance between sensitivity and specificity at the recommended cutoff level of ≤29, followed by the Braden scale and the Norton scale at recommended cutoff levels ≤18 versus ≤16, respectively. The modified Norton scale also reached an acceptable balance between sensitivity and specificity but at the cutoff level of ≤23, which is a higher cutoff level than recommended. General physical condition, physical activity, moisture, friction, and shear emerged as significant risk factors. CONCLUSIONS: The results support that the recommended cutoff levels of the RAPS, Norton, and Braden scales are valid in a general hospital setting. However, the recommended cutoff level of the modified Norton scale (≤20) has to be increased when used in this care context.

Different lying positions and their effects on tissue blood flow and skin temperature in older adult patients.

AIM: To report a study to compare the effects of different lying positions on tissue blood flow and skin temperature in older adult patients. This article reports the evaluation of study design and procedures. BACKGROUND: To reduce risk of pressure ulcers, repositioning of immobile patients is a standard nursing practice; however, research into how different lying positions effect tissue microcirculation is limited. DESIGN: Descriptive comparative design. METHODS: From March-October 2010, 20 inpatients, aged 65 years or older, were included in the study. Tissue blood flow and skin temperature were measured over bony prominences and in gluteus muscle in four supine and two lateral positions. RESULTS: The blood flow over the bony prominence areas was most influenced in the superficial skin and especially in the 30° lateral position, where the blood flow decreased significantly in comparison with the supine positions. There were significant individual differences in blood flow responses, but no common trend was identified among the patients considered at risk for pressure ulcer development. The study procedure worked well and was feasible to perform in an inpatient population. CONCLUSION: The lying positions seem to influence the tissue blood flow over the bony prominences in different ways in older adult inpatients, but further study is needed to confirm the results and to make recommendations to clinical practice. The study procedure worked well, although some minor adjustments with regard to heat accumulation will be made in future studies.

A new compression stocking with well-defined pressure-a randomized controlled pilot study.

BACKGROUND: To evaluate an innovative class I compression stocking with predetermined uniform pressure in comparison to a graduated class III compression stocking system, regarding edema reduction, interface pressure, and patient comfort. METHOD: Twenty-five patients with chronic venous disease, were randomized: 12 to investigational stocking, 13 to comparator stocking. Data collected at baseline and after 14 days. RESULTS: Edema was significantly equal reduced to follow-up; mean -129.0 cm3 (SD 105; p = .004, Class I) and -223.7 cm3 (SD 120; p = .002, Class III), respectively. The investigational stocking lost significantly less compression pressure than the comparator stocking (p ≤ .013). Participants in both groups perceived significant improvement regarding leg heaviness, leg swelling, and feelings of tightness and tingling (p ≤ .016). CONCLUSION: The innovative investigational class I stocking appears to offer similar edema reduction and benefits to the comparator class III stocking. However, a larger and prolonged study is required. The study was registered in the ISRCTN-registry, ISRCTN17356077, https://www.isrctn.com/ISRCTN17356077.

Evaluation of the Green Cross Method Regarding Patient Safety Culture and Incidence Reporting.

OBJECTIVES: The Green Cross (GC) method is a visual method for health service staff to recognize risks and preventable adverse events (PAEs) on a daily basis. The aim was to compare patient safety culture and the number of reported PAEs in units using the GC method with units that do not. METHODS: This study has a retrospective cross-sectional design in the setting of psychiatric and somatic care departments in a Swedish hospital. In total, 1476 staff members from 62 different units participate in the study. RESULTS: Units who had implemented the GC method scored higher than non-GC units in overall quality. The dimensions Feedback and communication about error, Nonpunitive response to errors, Organizational learning-continuous improvement, Handoffs and transitions between units and shifts, and Teamwork within units scored significantly higher in GC units. More risks were reported in the incident reporting system in GC units than in non-GC units, but the number of PAEs was similar. Units with nursing staff who used the GC method scored higher on patient safety culture than those who did not use the method. This difference was not seen in physician units. CONCLUSIONS: The implementation of the GC method has a positive impact on patient safety culture and PAE reporting. However, the method does not seem to have the same impact in physician units as in units with nursing staff, which calls for further investigation.

Monitoring Preventable Adverse Events and Near Misses: Number and Type Identified Differ Depending on Method Used.

OBJECTIVES: This study aimed to investigate how many preventable adverse events (PAEs) and near misses are identified through the methods structured record review, Web-based incident reporting (IR), and daily safety briefings, and to distinguish the type of events identified by each method. METHODS: One year of retrospective data from 2017 were collected from one patient cohort in a 422-bed acute care hospital. Preventable adverse events and near misses were collected from the hospital's existing resources and presented descriptively as number per 1000 patient-days. RESULTS: The structured record review identified 19.9 PAEs; the IR system, 3.4 PAEs; and daily safety briefings, 5.4 PAEs per 1000 patient-days. The most common PAEs identified by the record review method were drug-related PAEs, pressure ulcers, and hospital-acquired infections. The most common PAEs identified by the IR system and daily safety briefings were fall injury and pressure ulcers, followed by skin/superficial vessel injuries for the IR system and hospital-acquired infections for the daily safety briefings. Incident reporting and daily safety briefings identified 7.8 and 31.9 near misses per 1000 patient-days, respectively. The most common near misses were related to how care is organized. CONCLUSIONS: The different methods identified different amounts and types of PAEs and near misses. The study supports that health care organizations should adopt multiple methods to get a comprehensive review of the number and type of events occurring in their setting. Daily safety briefings seem to be a particularly suitable method for assessing an organization's inherent security and may foster a nonpunitive culture.

Knowledge, attitudes and practice among nursing staff concerning pressure ulcer prevention and treatment--a survey in a Swedish healthcare setting.

The aim of this study was to investigate (i) attitudes among Registered Nurses (RNs) and Nursing Assistants (NAs) regarding pressure ulcer prevention, (ii) knowledge among RNs and NAs of pressure ulcer prevention and treatment, (iii) practice of risk assessment and documentation regarding pressure ulcers among RNs and NAs and (iv) to identify perceived possibilities and barriers in pressure ulcer prevention and treatment. In this cross-sectional study, a total of 230 questionnaires were distributed to an equal number of RNs and NAs in both municipality as well as hospital care settings. The response rate was 67% (n = 154). In general, all respondents displayed good knowledge on prevention and treatment of pressure ulcers and demonstrated a positive attitude towards this area of care. However, answers provided to some questions indicate that recent research findings and guidelines have not succeeded in reaching out to these occupational groups. Furthermore, only 37% (n = 55) of the participants said that they have an agreed strategy for the prevention of pressure ulcers in their unit. These shortcomings may affect the quality of care provided to the patient and lead to pressure ulcers developing as a consequence. Today, evidence-based methods for risk assessment are available but are not adopted and used in practice. The study highlights the need to further reduce the gap between research and practice.

The effects of different lying positions on interface pressure, skin temperature, and tissue blood flow in nursing home residents.

BACKGROUND: Although repositioning is considered an important intervention to prevent pressure ulcers, tissue response during loading in different lying positions has not been adequately explored. AIM: To compare the effects of different lying positions on interface pressure, skin temperature, and tissue blood flow in nursing home residents. METHOD: From May 2011 to August 2012, interface pressure, skin temperature, and blood flow at three tissue depths were measured for 1 hr over the sacrum in 30° supine tilt and 0° supine positions and over the trochanter major in 30° lateral and 90° lateral positions in 25 residents aged 65 years or older. Measurement of interface pressure was accomplished using a pneumatic pressure transmitter connected to a digital manometer, skin temperature using a temperature sensor, and blood flow using photoplethysmography and laser Doppler flowmetry. RESULTS: Interface pressure was significantly higher in the 0° supine and 90° lateral positions than in 30° supine tilt and 30° lateral positions. The mean skin temperature increased from baseline in all positions. Blood flow was significantly higher in the 30° supine tilt position compared to the other positions. A hyperemic response in the post pressure period was seen at almost all tissue depths and positions. CONCLUSION: The 30° supine tilt position generated less interface pressure and allowed greater tissue perfusion, suggesting that this position is the most beneficial.
