The Role of Shear Stress and Shear Strain in Pressure Injury Development.

ABSTRACT: Although other patient safety indicators have seen a decline, pressure injury (PI) incidence has continued to rise. In this article, the authors discuss the role of shear stress and shear strain in PI development and describe how accurate assessment and management can reduce PI risk. They provide explanations of shear stress, shear strain, friction, and tissue deformation to support a better clinical understanding of how damaging these forces are for soft tissue. Clinicians must carefully assess each patient's risk factors regarding shear forces within the contexts of activity and mobility. The authors also provide a toolbox of mitigation strategies, including support surface selection, selection of materials that contact the individual, management of immobility using positioning techniques, and the use of safe patient handling techniques. With a clear understanding of how shear forces affect PI risk and mitigation strategies, clinicians will more accurately assess PI risk and improve PI prevention care plans, ultimately reducing PI incidence to become more aligned with other patient safety indicators.

Current Perspectives on Pressure Injuries in Persons with Dark Skin Tones from the National Pressure Injury Advisory Panel.

BACKGROUND: Pressure injury (PI) development is multifactorial. In patients with dark skin tones, identifying impending PIs by visual skin assessment can be especially challenging. The need for improved skin assessment techniques, especially for persons with dark skin tones, continues to increase. Similarly, greater awareness of the need for inclusivity with regard to representation of diverse skin colors/tones in education materials is apparent. OBJECTIVE: To provide current perspectives from the literature surrounding skin assessment and PI development in patients with dark skin tones. METHODS: The following elements will be discussed through the lens of skin tone: (1) historical perspectives of PI staging from the National Pressure Injury Advisory Panel, (2) epidemiology of PI, (3) anatomy and physiology of the skin, (3) skin tone assessment and measurement, (4) augmented visual assessment modalities, (5) PI prevention, (6) PI healing, (7) social determinants of health, and (8) gaps in clinician education. CONCLUSIONS: This article highlights the gap in our clinical knowledge regarding PIs in patients with dark skin tones. Racial disparities with regard to PI development and healing are especially clear among patients with dark skin tones. Skin tone color assessment must be standardized and quantifiable in clinical education, practice, and research. This work is urgently needed, and support from private and governmental agencies is essential.

Identifying Early-Phase Clinical Trial Participants at Risk for Experiencing Worse Clinical Outcomes.

PURPOSE: To identify early-phase clinical trial (EP-CT) participants at risk for experiencing worse clinical outcomes and describe receipt of supportive care services. METHODS: A retrospective review of the electronic health records of consecutive patients enrolled in EP-CTs from 2017 to 2019 examined baseline characteristics, clinical outcomes, and receipt of supportive care services. The validated Royal Marsden Hospital (RMH) prognosis score was calculated using data at the time of EP-CT enrollment (scores range from 0 to 3; scores ≥ 2 indicate poor prognosis). Differences in patient characteristics, clinical outcomes, and receipt of supportive care services were compared on the basis of RMH scores. RESULTS: Among 350 patients (median age = 63.2 years [range, 23.0-84.3 years], 57.1% female, 98.0% metastatic cancer), 31.7% had an RMH score indicating a poor prognosis. Those with poor prognosis RMH scores had worse overall survival (hazard ratio [HR], 2.00; P < .001), shorter time on trial (HR, 1.53; P < .001), and lower likelihood of completing the dose-limiting toxicity period (odds ratio, 0.42; P = .006) versus those with good prognosis scores. Patients with poor prognosis scores had greater risk of emergency room visits (HR, 1.66; P = .037) and hospitalizations (HR, 1.69; P = .016) while on trial, and earlier hospice enrollment (HR, 2.22; P = .006). Patients with poor prognosis scores were significantly more likely to receive palliative care consultation (46.8% v 27.6%; P < .001), but not other supportive care services. CONCLUSION: This study found that RMH prognosis score could identify patients at risk for decreased survival, shorter time on trial, and greater use of health care services. The findings underscore the need to develop supportive care interventions targeting EP-CT participants' distinct needs.

Best-practices for preventing skin injury beneath personal protective equipment during the COVID-19 pandemic: A position paper from the National Pressure Injury Advisory Panel.

COVID-19 has infected millions of patients and impacted healthcare workers worldwide. Personal Protective Equipment (PPE) is a key component of protecting frontline clinicians against infection. The benefits of PPE far outweigh the risks, nonetheless, many clinicians are exhibiting skin injury caused by PPE worn incorrectly. These skin injuries, ranging from lesions to open wounds are concerning because they increase the susceptibility of viral infection and transmission to other individuals. Early into the COVID-19 pandemic (April 2020), the U. S. National Pressure Injury Advisory Panel (NPIAP) developed a series of position statements to improve wear-ability of PPE and protect healthcare professionals and their patients as safe from harm as possible under the circumstances. The NPIAP positions, which were formed by conducting a systematic review of what was known at the time, include: (a) Prepare skin before and after wearing PPE with skin sealants, barrier creams and moisturisers; (b) Frequent PPE offloading to relieve pressure and shear applied to skin; (c) treat visible skin injuries immediately caused by PPE to minimise future infection; (d) non-porous dressings may provide additional skin protection, but lack evidence; (e) health systems should take care to educate clinicians about placement and personal hygiene related to handling PPE. Throughout all of these practices, handwashing remains a top priority to handle PPE. These NPIAP positions provided early guidance to reduce the risk of skin injury caused by PPE based on available research regarding PPE injuries, a cautious application of evidence-based recommendations on prevention of device-related pressure injuries in patients and the expert opinion of the NPIAP Board of Directors. Clinicians who adhere to these recommendations reduce the prospects of skin damage and long-term effects (e.g. scarring). These simple steps to minimise the risk of skin injury and reduce the risk of coronavirus infection from PPE can help.

Pressure Injury Development, Mitigation, and Outcomes of Patients Proned for Acute Respiratory Distress Syndrome.

OBJECTIVE: To describe trends and risk factors for pressure injuries (PIs) in adult critical care patients proned to alleviate acute respiratory distress syndrome secondary to COVID-19 and examine the effectiveness of products and strategies used to mitigate PIs. METHODS: The authors conducted a retrospective chart review between April 9 and June 8, 2020. Demographic data were analyzed using descriptive statistics. Differences between groups with and without PIs were analyzed. RESULTS: Among 147 patients, significant PI risk factors included male sex (P = .019), high body mass index (>40 kg/m2; P = .020), low Braden Scale score (<12; P = .018), and low-dose vasopressor therapy (P = .020). Taping endotracheal tubes (ETTs) caused significantly fewer facial PIs than commercial ETT holders (P < .0001). Maximum prone duration/session was a significant risk factor for anterior PIs (P = .016), which dropped 71% with newer pressure redistribution products. d-Dimer greater than 3,200 µg/mL (P = .042) was a significant risk factor for sacrococcygeal PIs while supine. Mortality was 30%; significant risk factors included age older than 60 years (P = .005), Sequential Organ Failure Assessment score greater than 11 (P = .003), and comorbid congestive heart failure (P = .016). CONCLUSIONS: Taping the ETT, limiting the maximum duration of prone positioning to less than 32 hours, and frequent repositioning while supine may reduce the number of modifiable risk factors for PIs. Standardized methods for testing products for PI prevention will inform individualized patient care.

Development of a Prone Team and Exploration of Staff Perceptions During COVID-19.

OBJECTIVE: As intensive care unit bed capacity doubled because of COVID-19 cases, nursing leaders created a prone team to support labor-intensive prone positioning of patients with COVID-related acute respiratory distress syndrome. The goal of the prone team was to reduce workload on intensive care teams, standardize the proning process, mitigate pressure injuries and turning-related adverse events, and ensure prone team safety. METHODS: Staff were trained using a hybrid learning model focused on prone-positioning techniques, pressure injury prevention, and turning-related adverse events. RESULTS: No adverse events occurred to patients or members of the prone team. The prone team mitigated pressure injuries using prevention strategies. The prone team and intensive care unit staff were highly satisfied with their experience. CONCLUSION: The prone team provided support for critically ill patients, and team members reported feeling supported and empowered. Intensive care unit staff were highly satisfied with the prone team.

Outcomes of a clinical nurse specialist-initiated wound care education program: using the promoting action on research implementation in health services framework.

Consistent with the sphere of clinical nurse specialist (CNS) practice related to advancing nursing practice and patient outcomes, a CNS task force of 20 of the 60 CNSs in our large teaching hospital was convened to plan, implement and evaluate a comprehensive wound care education program. The purpose of the program was to ensure the 24-7 hospital-wide availability of nurses with evidenced-based wound care knowledge and skills. The facilitative environment, in which the program was developed and operates, is analyzed using the Promoting Action on Research Implementation in Health Services framework. Outcomes of the CNS task force include (1) designation of unit-based CNS as the first line resources for wound care at the unit level, (2) education of almost 10% of the 3,800 nurses at Massachusetts General Hospital as staff nurse resources, and (3) a shift in the nature of CNS wound care consultations from prescription to validation of the staff nurse-initiated wound care plan.

Falls in the general hospital: association with delirium, advanced age, and specific surgical procedures.

BACKGROUND: Falls and delirium in general-hospital inpatients are related to increases in morbidity, mortality, and healthcare costs. Patients fall despite safeguards and programs to reduce falling. OBJECTIVE: The authors sought to determine the prevalence of diagnosed and undiagnosed delirium in patients who fell during their hospital stay. METHOD: The authors performed a retrospective electronic chart review of 252 patients who fell during their hospital stay. Falls were categorized by their severity (i.e., minor, moderate, and major). Demographic information, patient outcomes, and diagnostic criteria for delirium (per DSM-IV) were collected on the day of admission, the day of the fall, and the 2 days preceding the patient's fall. RESULTS: Falls in the general hospital were associated with delirium (both diagnosed and undiagnosed), advanced age, and specific surgical procedures. CONCLUSION: Improving the recognition of undiagnosed delirium may lead to sustainable and successful fall prevention programs. Detection of impairments in mental status can assist staff to create individualized patient care plans. Knowledge about which patients are at risk for injury from delirium and falls can lead to improvements in patient safety, functioning, and quality of life.

Successful implementation of an alcohol-withdrawal pathway in a general hospital.

BACKGROUND: Although alcohol use and abuse are common among general-hospital inpatients, many patients are inadequately assessed and treated for alcohol withdrawal. OBJECTIVE: The purpose of this study was to determine whether the implementation of a clinical pathway for the treatment of alcohol withdrawal in medical inpatients would result in improvements in clinical practice and patient outcomes. METHOD: Authors retrospectively reviewed 80 patient records (including 40 of those treated before the implementation of a pathway and 40 of those treated after pathway implementation). RESULTS: Assessment procedures and ordering patterns of physicians (medical house staff and staff physicians) shifted in a fashion consistent with the new treatment guidelines. Patient outcomes (e.g., length of stay and the incidence of delirium) improved for those patients who received benzodiazepines within the range of the pathway guidelines. CONCLUSIONS: Timely assessment and staff education can shift prescription patterns, increase patient monitoring, and reduce costs associated with alcohol withdrawal.

Measuring psychological insulin resistance: barriers to insulin use.

PURPOSE: The purpose of this study is to explore the attitudes that contribute to psychological insulin resistance (PIR) in insulin-naive patients with type 2 diabetes and to identify predictors of PIR. METHODS: A prospective study using 2 self-report surveys and incorporating demographic and health variables was conducted to determine the prevalence of PIR among a sample of 100 adult, insulin-naive patients with type 2 diabetes at an outpatient diabetes center in a university-affiliated teaching hospital. RESULTS: Thirty-three percent of patients with type 2 diabetes were unwilling to take insulin. The most commonly expressed negative attitudes were concern regarding hypoglycemia, permanent need for insulin therapy, less flexibility, and feelings of failure. Less than 40% expressed fear of self-injection or thought that injections were painful. However, compared with willing subjects, unwilling subjects were more likely to fear injections and thought injections would be painful, life would be less flexible, and taking insulin meant health would deteriorate (P< .005 for all comparisons). Poorer general health and higher depression scores also correlated with PIR. CONCLUSIONS: The results of the surveys, which were generally consistent, identified several remediable misconceptions regarding insulin therapy and suggest targets for educational interventions.

Promoting research utilization using a conceptual framework.

Since the early 1990s, evidence-based practice has gained momentum, but barriers persist between knowledge development and application in practice. The Massachusetts General Hospital re-engineered the Nursing Research Committee as one vehicle for promoting research-based practice. Using the Promoting Action on Research Implementation in Health Services framework, the mission and methods (context) to advance research-based practice are explicated. Characteristics of the membership, leadership, and practice environment that facilitate research utilization are delineated.

Peripheral arterial sheath removal program: a performance improvement initiative.

The increasing number of endovascular procedures by both cardiologists and vascular surgeons strain available resources, such as recovery space, creating delays in the throughput of patients. The use of alternative settings, personnel, and approaches to postprocedural care has been proposed to maximize the number of procedures that can be done with existing procedure rooms. However, a key question remains about whether this can be done safely and achieve good patient outcomes. A performance improvement project was conducted to evaluate the safety and effectiveness of shifting postprocedural care and removal of intraarterial sheaths by the staff in the cardiac catheterization laboratory to specially trained acute care nurses on an inpatient vascular surgical unit. The purpose of this project was to develop a performance improvement project that included administrative, educational, and clinical components and to evaluate effects on key patient outcomes, prospectively, over 15 months.

The cost and efficacy of two wound treatments.

Using the physiology of moist wound healing as the framework, this nonexperimental, retrospective chart review compared the rate of wound healing and cost of wound care associated with wet-to-dry normal saline gauze dressings to the rate of wound healing and cost of wound care associated with amorphous hydrogel dressings for patients with infrainguinal arterial disease and diabetes. These patients were discharged from the hospital to home care for management of perioperative arterial surgical wound dehiscence and nonhealing ulcerations. The sample included 25 patients who used wet-to-dry normal saline gauze dressings and 25 patients who used amorphous hydrogel dressings. Repeated measures of analysis of covariance revealed a similar rate of wound healing in the two groups. The overall cost of wound care was significantly higher (P = .006) for patients in the normal saline group, with a higher number and cost of home nursing visits. The cost of supplies was not significantly different between groups, although amorphous hydrogel dressings cost an average of dollar 50 more than wet-to-dry normal saline gauze dressings. The two treatments are equally efficacious in promoting wound healing, but amorphous hydrogel dressings are significantly more cost effective and, thus, a better value for the home care dollar.
