Predicting Pressure Injury in Critical Care Patients: A Machine-Learning ModelBACKGROUND: Hospital-acquired pressure injuries are a serious problem among critical care patients. Some can be prevented by using measures such as specialty beds, which are not feasible for every patient because of costs. However, decisions about which patient would benefit most from a specialty bed are difficult because results of existing tools to determine risk for pressure injury indicate that most critical care patients are at high risk. OBJECTIVE: To develop a model for predicting development of pressure injuries among surgical critical care patients. METHODS: Data from electronic health records were divided into training (67%) and testing (33%) data sets, and a model was developed by using a random forest algorithm via the R package "randomforest." RESULTS: Among a sample of 6376 patients, hospital-acquired pressure injuries of stage 1 or greater (outcome variable 1) developed in 516 patients (8.1%) and injuries of stage 2 or greater (outcome variable 2) developed in 257 (4.0%). Random forest models were developed to predict stage 1 and greater and stage 2 and greater injuries by using the testing set to evaluate classifier performance. The area under the receiver operating characteristic curve for both models was 0.79. CONCLUSION: This machine-learning approach differs from other available models because it does not require clinicians to input information into a tool (eg, the Braden Scale). Rather, it uses information readily available in electronic health records. Next steps include testing in an independent sample and then calibration to optimize specificity.
Risk factors for pressure injuries among critical care patients: A systematic reviewJenny Alderden, June Rondinelli, Ginette A. Pepper et al.|International Journal of Nursing Studies|2017 OBJECTIVE: To identify risk factors independently predictive of pressure injury (also known as pressure ulcer) development among critical-care patients. DESIGN: We undertook a systematic review of primary research based on standardized criteria set forth by the Institute of Medicine. DATA SOURCES: We searched the following databases: CINAHL (EBSCOhost), the Cochrane Library (Wilson), Dissertations & Theses Global (ProQuest), PubMed (National Library of Medicine), and Scopus. There was no language restriction. METHOD: A research librarian coordinated the search strategy. Articles that potentially met inclusion criteria were screened by two investigators. Among the articles that met selection criteria, one investigator extracted data and a second investigator reviewed the data for accuracy. Based on a literature search, we developed a tool for assessing study quality using a combination of currently available tools and expert input. We used the method developed by Coleman et al. in 2014 to generate evidence tables and a summary narrative synthesis by domain and subdomain. RESULTS: Of 1753 abstracts reviewed, 158 were identified as potentially eligible and 18 fulfilled eligibility criteria. Five studies were classified as high quality, two were moderate quality, nine were low quality, and two were of very low quality. Age, mobility/activity, perfusion, and vasopressor infusion emerged as important risk factors for pressure injury development, whereas results for risk categories that are theoretically important, including nutrition, and skin/pressure injury status, were mixed. Methodological limitations across studies limited the generalizability of the results, and future research is needed, particularly to evaluate risk conferred by altered nutrition and skin/pressure injury status, and to further elucidate the effects of perfusion-related variables. CONCLUSIONS: Results underscore the importance of avoiding overinterpretation of a single study, and the importance of taking study quality into consideration when reviewing risk factors. Maximal pressure injury prevention efforts are particularly important among critical-care patients who are older, have altered mobility, experience poor perfusion, or who are receiving a vasopressor infusion.
Risk Profile Characteristics Associated With Outcomes of Hospital-Acquired Pressure Ulcers: A Retrospective ReviewBACKGROUND: Hospital-acquired pressure ulcers are a common problem. Although a number of risk factors have been identified, relationships among risk profile characteristics and pressure ulcer outcomes have not been described in hospitalized patients. OBJECTIVES: To describe patients' characteristics and risk factors associated with pressure ulcer outcome. METHODS: A retrospective chart review was used to collect data on 87 patients in whom hospital-acquired pressure ulcers developed from May 2007 to November 2008. All pressure ulcers were staged by a certified wound nurse. Relationships among risk profile characteristics and pressure ulcer outcomes were determined via bivariate analysis and multivariate logistic regression. RESULTS: High severity of illness was present in patients with hospital-acquired pressure ulcers; 89% were intensive care patients. Vasopressor infusion, spinal cord injury, and age 40 or greater conferred risk for nonhealing pressure ulcers. Among pressure ulcer stages, suspected deep tissue injury ulcers were less likely to heal. CONCLUSIONS: Identification of characteristics and risk factors associated with development of nonhealing hospital-acquired pressure ulcers will allow nurses to recognize patients at risk for nonhealing and to take aggressive preventative measures.
<scp>WHS</scp> guidelines for the treatment of pressure ulcers—2023 updateLisa J. Gould, Jenny Alderden, Rummana Aslam et al.|Wound Repair and Regeneration|2023 The major populations at risk for developing pressure ulcers are older adults who have multiple risk factors that increase their vulnerability, people who are critically ill and those with spinal cord injury/disease. The reported prevalence of pressure ulcers in the United States is 2.5 million. However, this estimate is derived from acute care facilities and does not include people who are living at home or in nursing facilities. Despite the implementation of hospital and facility-based preventive measures, the incidence of pressure ulcers has not decreased in decades. In addition to the burden of pain, infection and death, it is estimated that hospital-acquired pressure ulcers cost the health system $26.8 billion annually with over 50% of the cost attributed to treating Stage 3 and 4 pressure injuries. Thus, it is critical to examine the literature and develop guidelines that will improve the outcomes of this complex and costly condition. This guideline update is a compendium of the best available evidence for the treatment of Pressure Ulcers published since the last update in 2015 and includes a new section based on changing demographics entitled 'Palliative wound care for seriously ill patients with pressure ulcers'. The overall goal of the Wound Healing Society Guideline project is to present clear, concise and commercial free guidelines that clinicians can use to guide care, that researchers can use to develop studies that will improve treatment and that both clinicians and researchers can use to understand the gaps in our knowledge base.
Mitigating the Effects of a Pandemic: Facilitating Improved Nursing Home Care Delivery Through TechnologyThe coronavirus disease (COVID-19) pandemic has been particularly challenging for nursing home staff and residents. Centers for Medicare & Medicaid Services regulation waivers are burdening staff and affecting how care is delivered. Residents are experiencing social isolation, which can result in physical and behavioral health issues, particularly for persons with dementia. These challenges can be addressed in part through technology adaptations. Full integration of electronic health record systems can improve workflow and care quality. Telehealth can improve access to outside providers, provide remote monitoring, and improve social connectedness. Electronic and audiovisual programs can be used for end-of-life planning and information sharing between nursing home staff and families. Online learning systems and other online resources provide flexible options for staff education and training. Investing in and adapting technology can help mitigate workforce stress and improve the quality of nursing home care during and after the COVID-19 crisis.
