Doxycycline-loaded carboxymethyl cellulose/sodium alginate/gelatin hydrogel: An approach for enhancing pressure ulcer healing in a rat model.

Pressure ulcers, or bedsores, are created by areas of the skin under prolonged pressure and can lead to skin and underlying tissue damage. The present study evaluated the effects of carboxymethyl cellulose/sodium alginate/gelatin (CMC/Alg/Gel) hydrogel containing doxycycline (DOX) on improving the healing process of pressure ulcers. The magnet was used to apply pressure on the dorsum skin rat to induce a pressure ulcer model. Then sterile gauze, CMC/Alg/Gel, and CMC/Alg/Gel/1% w/v DOX hydrogels were used to cover the wounds. Blood compatibility, weight loss, cytocompatibility, drug release rate, cell viability, wound closure, and re-epithelialization were evaluated in all animals on the 14th day after treatment. In vivo results and histopathological evaluation showed 56.66% wound closure and the highest re-epithelialization in the CMC/Alg/Gel/1% w/v DOX hydrogel group (14 days after treatment). Furthermore, real-time PCR results indicated that the hydrogel containing DOX significantly decreased the expression of the MMP family consisting of MMP2 and MMP9 mRNA and also increased the expression of vascular endothelial growth factor VEGF mRNA. This study suggested that the addition of DOX, an antibiotic and MMP inhibitor, to hydrogels may be effective in the healing process of pressure ulcers.

Prevalence of pressure ulcers and associated factors among adult patients admitted at Comprehensive Specialized Hospital, Northwest Ethiopia, 2023.

Pressure ulcers are a serious concern in patients with prolonged bedtime and present with common complications following surgery. It is one of the key performance indicators of the quality of nursing care provided to patients. Several studies have reported the prevalence of pressure ulcers in Ethiopia, but the current study area has not yet been fully addressed. Hence, the study aims to assess pressure ulcers and their associated factors among adult patients admitted to the surgical ward. An institution-based, cross-sectional study was conducted from April 15 to May 15, 2023. A systematic random sampling technique was used to select 480 patients. A standardized, pre-tested, and structured questionnaire was used. The results were presented descriptively using tables and figures. A binary logistic regression was used to assess associated factors. From a total of 480, all patients have participated with a 100% response rate. The prevalence rate of pressure ulcers was 10.2%. Being smoker [95% CI AOR 7.46 (2.64, 21.06)], bedridden [95% CI AOR 3.92 (1.28, 11.66)], having a length of hospital stay of greater than 20 days [95% CI AOR 3.01 (1.13, 8.02)], experiencing pain [95% CI AOR 3.20 (1.06, 7.51)], or having friction and shear [95% CI AOR 5.71 (1.91, 17.08)], were significantly associated with pressure ulcers. This study showed that a considerable proportion of patients had pressure ulcers. Smoking, having pain, being bedridden, being exposed to friction and shear problems, and length of hospital stay were significantly associated with pressure ulcers. Healthcare providers should educate patients about smoking risks, pain management, mattress installation, and linen care.

Bedsore Healing Using Selenium-Enriched Lactobacillus brevis LSe: A Randomized, Double-Blind, Controlled Clinical Trial.

Bedsores impose an important challenge to the healthcare system. Se-baring probiotics are considered effective agents in wound healing and inflammation reduction via several pathways. The present study focused on the administration of a Se-enriched probiotic, originally obtained from a traditional dairy product for bedsore healing. Daily doses of the probiotic were administered to 20 ICU patients for 14 days and the wound healing criteria were compared with those of the same group of ICU patients as control, both groups suffering from stages I and II bedsore (a randomized, double-blind, controlled clinical trial). The administered Se-enriched probiotic decreased the bedsore healing period significantly (on average by 2.4 days, P-value: 0.039), as well as bedsore size (on average by 7 mm2, nonsignificant) and bedsore grade (10%, nonsignificant) in the treatment group more efficiently than the control group. Some key laboratory parameters associated with inflammation were also improved in patients receiving the Se-supplemented probiotic. The limitations of this study include the low number of patients meeting inclusion criteria within the timeframe of the study, and the impossibility of following up patients after discharge from the ICU. In summary, this study revealed the effectiveness of the Se-enriched probiotic in bedsore improvement, suggesting consideration of the enriched probiotic as an auxiliary agent in bedsore management.

A Novel Potential Treatment for Diabetic Foot Ulcers and Non-Healing Ulcers - Case Series.

INTRODUCTION: Appropriate care and treatment of a wound is the need of the hour whether it is an infected or a non-infected wound. If wound healing is delayed for some reason, it leads to serious complications and further increases the hospital stay and cost of treatment. Herein, we describe a novel antimicrobial wound dressing formulation (VG111), with an objective to generate the preliminary data showing the distinct advantages in various types of wounds. METHOD: This case series involved the treatment of acute cases of wounds or chronic wounds that did not respond well to conventional wound healing treatments with VG111 in patients with different etiologies. Thirteen cases of patients that included patients with diabetes, pressure ulcers, burns, trauma, and others treated with VG111 showed rapid wound healing in all the cases, even obviating the need for a graft when complete skin regeneration occurred RESULT: This was illustrated by clearing of the wound infections, reduction/disappearance of the exudate, appearance of intense granulation, epithelialization, and anti-biofilm activity followed by complete wound closure. This VG111 precludes the need for systemic antimicrobial agents in localized infections and therefore, this single agent is an attempt to address the limitations and the drawbacks of the available products. CONCLUSION: Despite patients belonging to the old age group and having comorbidities like diabetes, still VG111 showed effective rapid wound healing, and that too without any scar formation in hardto-heal, infected, and non-infected wounds

Wearable Prophylaxis Tool for AI-Driven Identification of Early Warning Patterns of Pressure Ulcers.

As today's society ages, age-related diseases become more frequent. One very common but yet preventable disease is the development of pressure ulcers (PUs). PUs can occur if tissue is exposed to a long-lasting pressure load, e.g., lying on tissue without turning. The cure of PUs requires intensive care, especially for the elderly or people with preexisting conditions whose tissue needs longer healing times. The consequences are heavy suffering for the patient and extreme costs for the health care system. To avoid these consequences, our objective is to develop a pressure ulcer prophylaxis device. For that, we built a new sensor system able to monitor the pressure load and tissue vital signs in immediate local proximity at patient's predilection sites. In the clinical study, we found several indicators showing correlations between tissue perfusion and the risk of PU development, including strongly reduced SpO2 levels in body tissue prior to a diagnosed PU. Finally, we propose a prophylaxis system that allows for the prediction of PU developments in early stages before they become visible. This work is the first step in generating an effective system to warn patients or caregivers about developing PUs and taking appropriate preventative measures. Widespread application could reduce patient suffering and lead to substantial cost savings.

Effect of various repositioning regimens on pressure wound ulcer occurrence in at-risk adult persons without existing pressure wound ulcers: A meta-analysis.

Meta-analysis research was implemented to appraise the effect of various repositioning regimens (RRs) on pressure wound ulcer (PWU) occurrence in at-risk adult persons without existing PWUs. Inclusive literature research till April 2023 was done and 1197 interconnected researches were revised. The 15 picked researches, enclosed 8510 at-risk adult persons without existing PWUs persons were in the utilised researchers' starting point, 1002 of them were utilising repositioning, 1069 were control, 3443 were utilising 2-<4 h repositioning and 2994 were utilising 4-6 h repositioning. Odds ratio (OR) and 95% confidence intervals (CIs) were utilised to appraise the consequence of various RRs on PWU occurrence in at-risk adult persons without existing PWUs by the dichotomous approach and a fixed or random model. Repositioning had significantly lower PWU (OR, 0.49; 95% CI, 0.32-0.73, p < 0.001) compared to control in at-risk adult persons without existing PWUs persons. 2-<4 h repositioning had significantly lower PWU (OR, 0.62; 95% CI, 0.42-0.90, p = 0.01) compared to 4-6 h repositioning in at-risk adult persons without existing PWUs persons. Repositioning had significantly lower PWU compared to control in at-risk adult persons without existing PWU persons. 2-<4 h repositioning had significantly lower PWU compared to 4-6 h repositioning in at-risk adult persons without existing PWUs persons. However, caution needs to be taken when interacting with its values since there was a low sample size of some of the chosen research found for the comparisons in the meta-analysis.

A Comprehensive and Improved Definition for Hospital-Acquired Pressure Injury Classification Based on Electronic Health Records: Comparative Study.

BACKGROUND: Patients develop pressure injuries (PIs) in the hospital owing to low mobility, exposure to localized pressure, circulatory conditions, and other predisposing factors. Over 2.5 million Americans develop PIs annually. The Center for Medicare and Medicaid considers hospital-acquired PIs (HAPIs) as the most frequent preventable event, and they are the second most common claim in lawsuits. With the growing use of electronic health records (EHRs) in hospitals, an opportunity exists to build machine learning models to identify and predict HAPI rather than relying on occasional manual assessments by human experts. However, accurate computational models rely on high-quality HAPI data labels. Unfortunately, the different data sources within EHRs can provide conflicting information on HAPI occurrence in the same patient. Furthermore, the existing definitions of HAPI disagree with each other, even within the same patient population. The inconsistent criteria make it impossible to benchmark machine learning methods to predict HAPI. OBJECTIVE: The objective of this project was threefold. We aimed to identify discrepancies in HAPI sources within EHRs, to develop a comprehensive definition for HAPI classification using data from all EHR sources, and to illustrate the importance of an improved HAPI definition. METHODS: We assessed the congruence among HAPI occurrences documented in clinical notes, diagnosis codes, procedure codes, and chart events from the Medical Information Mart for Intensive Care III database. We analyzed the criteria used for the 3 existing HAPI definitions and their adherence to the regulatory guidelines. We proposed the Emory HAPI (EHAPI), which is an improved and more comprehensive HAPI definition. We then evaluated the importance of the labels in training a HAPI classification model using tree-based and sequential neural network classifiers. RESULTS: We illustrate the complexity of defining HAPI, with <13% of hospital stays having at least 3 PI indications documented across 4 data sources. Although chart events were the most common indicator, it was the only PI documentation for >49% of the stays. We demonstrate a lack of congruence across existing HAPI definitions and EHAPI, with only 219 stays having a consensus positive label. Our analysis highlights the importance of our improved HAPI definition, with classifiers trained using our labels outperforming others on a small manually labeled set from nurse annotators and a consensus set in which all definitions agreed on the label. CONCLUSIONS: Standardized HAPI definitions are important for accurately assessing HAPI nursing quality metric and determining HAPI incidence for preventive measures. We demonstrate the complexity of defining an occurrence of HAPI, given the conflicting and incomplete EHR data. Our EHAPI definition has favorable properties, making it a suitable candidate for HAPI classification tasks.

A systematic review of nurses' practice and related factors toward pressure ulcer prevention.

In most health care centres, pressure ulcers (PUs) are a common concern. This systematic review aimed to summarise nurses' practice and related factors toward PU prevention. An extensive search was conducted on electronic databases such as Scopus, PubMed, Web of Science, Iranmedex, and Scientific Information Database via keywords extracted from Medical Subject Headings such as "Pressure ulcer", "Pressure sore", "Bedsore", "Practice", and "Nurses" from the earliest to 9 March 2022. The quality of the included studies was assessed using the appraisal tool for cross-sectional studies (AXIS tool). Data extraction and quality assessment of included studies were performed by two researchers independently. A total of 6501 nurses were enrolled in twenty-nine studies. Of the participants, 75.15% were female and 55.64% were single, and 94.57% had a bachelor of science in nursing degree. Mean age and work experience of nurses was 30.69 (SD = 4.73) and 8.61 (SD = 5.44) years, respectively. The mean score of nurses' practices toward the prevention of PUs was 57.58 (SD = 14.62) out of 100. Also, 48.95% of nurses had a desirable practice toward the prevention of PUs. Factors such as knowledge (n = 6), attitude (n = 4), level of education (n = 4), a history of participating in workshops related to the prevention of PUs (n = 3), work experience (n = 2), area of practice (n = 2), self-adequacy (n = 1), follow the literature (n = 1), age (n = 1), and involvement in research (n = 1) had a significant positive relationship with nurses' practice toward PUs prevention. However, the nurses practice of PUs prevention had a significant negative relationship with lack of job satisfaction (n = 1), disproportionate nurse-to-patient ratio (n = 1), and lack of policies and guidelines (n = 1). The level of nurses' practice toward the prevention of PUs was relatively desirable. The result of this study can help improve the practice of nurses toward PUs prevention. Increasing nurses' knowledge and attitude toward PUs prevention can improve their practice. Therefore, it is suggested that policymakers and nursing managers implement PUs prevention education for nurses based on the factors associated with nurses' practice.

Efficacy and Safety of Topical Application of Olive Oil for Preventing Pressure Ulcers: A Systematic Review and Meta-Analysis of Randomized Controlled Trials.

The purpose was to identify and summarize the existing evidence on the efficacy and safety of the topical application of olive oil for preventing pressure ulcers (PUs). We included only randomized controlled trials (RCTs) involving patients at risk of developing PUs, testing the topical application of olive oil versus other products for PU prevention. We assessed the risk of bias using the RoB 2 tool, and the certainty of the evidence with GRADE. Four RCTs met the eligibility criteria. All studies were judged at a low risk of bias overall. The meta-analysis showed that the clinical efficacy of olive oil for prevention occurs by reducing the incidence of PUs (RR = 0.56, 95% CI = 0.30 to 0.79, I2 = 0%); with no differences in adverse effects, it may be associated with a shorter development time of PUs and shorter hospital stays. The certainty of the evidence assessed by the GRADE approach was moderate and low. The topical application of olive oil is effective and safe in reducing the incidence of PUs compared to other treatments. These findings could provide new insights into olive oil as a preventive and alternative treatment for PUs as it is accessible and inexpensive compared to other products.

An artificial intelligence-enabled smartphone app for real-time pressure injury assessment.

The management of chronic wounds in the elderly such as pressure injury (also known as bedsore or pressure ulcer) is increasingly important in an ageing population. Accurate classification of the stage of pressure injury is important for wound care planning. Nonetheless, the expertise required for staging is often not available in a residential care home setting. Artificial-intelligence (AI)-based computer vision techniques have opened up opportunities to harness the inbuilt camera in modern smartphones to support pressure injury staging by nursing home carers. In this paper, we summarise the recent development of smartphone or tablet-based applications for wound assessment. Furthermore, we present a new smartphone application (app) to perform real-time detection and staging classification of pressure injury wounds using a deep learning-based object detection system, YOLOv4. Based on our validation set of 144 photos, our app obtained an overall prediction accuracy of 63.2%. The per-class prediction specificity is generally high (85.1%-100%), but have variable sensitivity: 73.3% (stage 1 vs. others), 37% (stage 2 vs. others), 76.7 (stage 3 vs. others), 70% (stage 4 vs. others), and 55.6% (unstageable vs. others). Using another independent test set, 8 out of 10 images were predicted correctly by the YOLOv4 model. When deployed in a real-life setting with two different ambient brightness levels with three different Android phone models, the prediction accuracy of the 10 test images ranges from 80 to 90%, which highlight the importance of evaluation of mobile health (mHealth) application in a simulated real-life setting. This study details the development and evaluation process and demonstrates the feasibility of applying such a real-time staging app in wound care management.

Pressure Injury on Poststroke Admission Assessment to Skilled Nursing Facilities: Risk Factors, Management, and Impact on Rehabilitation.

OBJECTIVE: To describe pressure injury (PrI) prevalence, comorbidities, and rehabilitation utilization among older adults with stroke at skilled nursing facilities' (SNFs') admission assessment. DESIGN: Retrospective cohort. SETTING AND PARTICIPANTS: Older Medicare beneficiaries (>65 years old) with stroke admitted to SNFs. METHODS: We extracted data between 2013 and 2014 using the Master Beneficiary Summary, Medicare Provider Analysis and Review, and Minimum Data Set 3.0. PI data were assessed during admission assessment. RESULTS: Of the 65,330 older adults poststroke admitted to SNFs, 11% had at least 1 PrI present on admission assessment. Individuals who were non-Hispanic Black, with a longer hospital stay, from lower socioeconomic status, with higher proportions of comorbidities (eg, underweight, urinary and bowel incontinence, diabetes, congestive heart failure, arrhythmias, and infections), and higher functional impairments were likely to present with a PrI at SNF admission assessment. Compared with individuals with superficial PrI, individuals with deep PrI were more likely to be young-old (<75 years), non-Hispanic Black, from lower socioeconomic status, present with a shorter hospital stay, an intensive care unit stay, with higher functional impairments, skin integrity issues, system failure, and infections. Compared to those without PrI or superficial PrI, individuals with any-stage PrI or deep PrI were more likely to be cotreated by physical and occupational therapist and less likely to receive individual therapy. Those with PrI poststroke had low documented turning and repositioning rates than those without PrI. CONCLUSIONS AND IMPLICATIONS: Identifying modifiable risk factors to prevent PrIs poststroke in SNFs will facilitate targeted preventative interventions and improve wound care efficacy and rehabilitation utilization for optimized patient outcomes. Identifying residents with a higher risk of PrI during acute care discharge and providing early preventive care during post-acute care would possibly decrease costs and improve outcome quality.

Application of damage control surgery in patients with sacrococcygeal deep decubitus ulcers complicated by sepsis.

OBJECTIVE: To evaluate the clinical application of damage control surgery (DCS) in patients with sacrococcygeal deep decubitus ulcers complicated by sepsis. METHODS: We conducted a 3-year retrospective clinical study of 32 patients with deep sacrococcygeal bedsores and sepsis admitted from January 2018 to January 2021. According to the concept of DCS, the wound was temporarily closed with vacuum sealing drainage after primary debridement, and a local rhomboid flap was designed to repair the wound in the second stage. Finally, the clinical therapeutic effect was observed. RESULTS: Twenty-nine patients were treated with skin flap translocation and were cured clinically. Specifically, the skin flap survived in 27 of the 29 patients after the first translocation attempt (success rate of 93.1%). One patient developed incisional dehiscence, and one patient developed a hydrocele under the skin flap. CONCLUSIONS: Application of DCS in patients with sacrococcygeal deep decubitus ulcers complicated by sepsis improves the therapeutic success rate and reduces the risks of the operation and complication rate. It has unique advantages and is worthy of clinical promotion.

Pattern and outcome of traumatic spinal cord injury managed at University of Maiduguri Teaching Hospital, Nigeria: A retrospective study.

BACKGROUND: Understanding pattern and outcome of traumatic spinal cord injury (TSCI) will inform better management which expectedly would improve prognosis and minimise complications. METHODS: : A retrospective study was carried out on all managed TSCI cases from January 2009 to December 2018. Sociodemographic characteristics, injury type, cause and complications were extracted from patients' registers and case folders. Descriptive statistics summarised the data, and Fisher's exact test analysed associations between variables. RESULTS: Eighty-one cases met the inclusion criteria and were analysed. Most cases (91.4%) were males, aged 18-39 years (65.4%) and were civil servants (37.0%). Road traffic accident (RTA) was the leading cause of injury (37.0%) and incomplete lesion predominated (69.1%). Cases referred for physiotherapy constituted 77.8%, only 14.8% of cases recovered without neurological deficits. On discharge, most patients were wheelchair bound (33.3%). Region of spine affected showed significant association with complications developed (P = 0.01). RTA caused more dead as a cause of injury was found to be significantly associated with outcome (P = 0.04). Referral for physiotherapy showed significant association with outcome (P = 0.01), so also, region of spine affected with outcome (0.01). The study found a significant association between type of injury and functional status (P = 0.01). CONCLUSIONS: : The study concludes that young adults of working class were mostly affected, and RTA and gunshots injuries were the leading causes of TSCI. Findings such as the association found between regions of spine affect and complication developed on admission will help healthcare providers identify those susceptible and offer prompt preventive measures.

Using Machine Learning Technologies in Pressure Injury Management: Systematic Review.

BACKGROUND: Pressure injury (PI) is a common and preventable problem, yet it is a challenge for at least two reasons. First, the nurse shortage is a worldwide phenomenon. Second, the majority of nurses have insufficient PI-related knowledge. Machine learning (ML) technologies can contribute to lessening the burden on medical staff by improving the prognosis and diagnostic accuracy of PI. To the best of our knowledge, there is no existing systematic review that evaluates how the current ML technologies are being used in PI management. OBJECTIVE: The objective of this review was to synthesize and evaluate the literature regarding the use of ML technologies in PI management, and identify their strengths and weaknesses, as well as to identify improvement opportunities for future research and practice. METHODS: We conducted an extensive search on PubMed, EMBASE, Web of Science, Cumulative Index to Nursing and Allied Health Literature (CINAHL), Cochrane Library, China National Knowledge Infrastructure (CNKI), the Wanfang database, the VIP database, and the China Biomedical Literature Database (CBM) to identify relevant articles. Searches were performed in June 2020. Two independent investigators conducted study selection, data extraction, and quality appraisal. Risk of bias was assessed using the Prediction model Risk Of Bias ASsessment Tool (PROBAST). RESULTS: A total of 32 articles met the inclusion criteria. Twelve of those articles (38%) reported using ML technologies to develop predictive models to identify risk factors, 11 (34%) reported using them in posture detection and recognition, and 9 (28%) reported using them in image analysis for tissue classification and measurement of PI wounds. These articles presented various algorithms and measured outcomes. The overall risk of bias was judged as high. CONCLUSIONS: There is an array of emerging ML technologies being used in PI management, and their results in the laboratory show great promise. Future research should apply these technologies on a large scale with clinical data to further verify and improve their effectiveness, as well as to improve the methodological quality.

Prevalence of pressure ulcers among hospitalized adult patients in Ethiopia: a systematic review and meta-analysis.

BACKGROUND: Globally, PUs are recognized as one of the five most frequent causes of harm to clients. With millions affected globally, the national pooled prevalence of pressure ulcers in Ethiopia remains unknown. Hence, this review and meta-analysis aimed to determine the prevalence of pressure ulcers among hospitalized clients in Ethiopia. METHODS: Studies were retrieved through search engines in PubMed, Scopus, WHO Afro Library, Google Scholar, Africa Journals Online, and Web of Science. Heterogeneity between-studies were checked using the I2 test. A funnel plot and Egger's regression test was used to assess the presence of publication bias. The random-effect model was fitted to estimate summary effects and 95% confidence intervals (CIs) across studies. The analyses were performed using STATA™ Version 14 software. RESULTS: The pooled prevalence of pressure ulcer in Ethiopia was assessed using seven studies involving a total of 1881 participants. The pooled prevalence of pressure ulcers in Ethiopia was 11.7% (95% CI: 7.28, 16.13). The subgroup analysis showed that the estimated magnitude of pressure ulcers was 15.89% (95% CI: 13.32, 18.46); among studies, their sample size was greater than or equal to 250. CONCLUSION: The current review reported that the pooled prevalence of pressure ulcers in Ethiopia was relatively high. Hence, policymaker and healthcare providers should give attention to reduce the magnitude of pressure ulcers. Furthermore, further a meta-analysis study could be conducted to identify individual and health care service-related factors related to the occurrence of pressure ulcers.

Silencing circular RNA circANKRD36 remits lipopolysaccharide-induced inflammatory damage by regulating microRNA-15/MyD88.

Bedsore is a familiar disease, which fearfully harms the health of the patients. We investigated the efficacy and mechanism of circular RNA circANKRD36 on HaCaT cell in inflammatory damage. CCK-8 and flow cytometry were respectively used to investigate the efficacies of lipopolysaccharide (LPS), circANKRD36, and microRNA (miR)-15 on cell viability and apoptosis. Moreover, circANKRD36 and miR-15 expression were changed by cell transfection and investigated by reverse transcription-quantitative polymerase chain reaction. Furthermore, the levels of Bax, pro caspase-3, cleaved caspase-3, interleukin (IL)-1ß, IL-6, and proteins of the pathway were investigated by Western blot. Otherwise, the levels of IL-1ß and IL-6 were investigated by enzyme-linked immunosorbent assay. Reactive oxygen species (ROS) was investigated by ROS assay. The relation between myeloid differentiation factor 88 (MyD88) and miR-15 was investigated by luciferase assay. LPS caused inflammatory damage and upregulated circANKRD36. circANKRD36 was silenced in cells and si-circANKRD36 remitted inflammatory damage. Furthermore, si-circANKRD36 negatively regulated miR-15 and miR-15 inhibitor could reverse the efficacies of si-circANKRD36. Besides, si-circANKRD36 restrained the NF-κB pathway by upregulating miR-15. Finally, MyD88 was authenticated as a target of miR-15. circANKRD36 remitted cell inflammatory damage upregulating miR-15/MyD88 via the NF-κB pathway in HaCaT cells.

Effect of a wearable patient sensor on care delivery for preventing pressure injuries in acutely ill adults: A pragmatic randomized clinical trial (LS-HAPI study).

IMPORTANCE: Though theoretically sound, studies have failed to demonstrate the benefit of routine repositioning of at-risk patients for the prevention of hospital acquired pressure injuries. OBJECTIVE: To assess the clinical effectiveness of a wearable patient sensor to improve care delivery and patient outcomes by increasing the total time with turning compliance and preventing pressure injuries in acutely ill patients. DESIGN: Pragmatic, investigator initiated, open label, single site, randomized clinical trial. SETTING: Two Intensive Care Units in a large Academic Medical Center in California. PARTICIPANTS: Consecutive adult patients admitted to one of two Intensive Care Units between September 2015 to January 2016 were included (n = 1564). Of the eligible patients, 1312 underwent randomization. INTERVENTION: Patients received either turning care relying on traditional turn reminders and standard practices (control group, n = 653), or optimal turning practices, influenced by real-time data derived from a wearable patient sensor (treatment group, n = 659). MAIN OUTCOME(S) AND MEASURE(S): The primary and secondary outcomes of interest were occurrence of hospital acquired pressure injury and turning compliance. Sensitivity analysis was performed to compare intention-to-treat and per-protocol effects. RESULTS: The mean age was 60 years (SD, 17 years); 55% were male. We analyzed 103,000 h of monitoring data. Overall the intervention group had significantly fewer Hospital Acquired Pressure Injuries during Intensive Care Unit admission than the control group (5 patients [0.7%] vs. 15 patients [2.3%] (OR = 0.33, 95%CI [0.12, 0.90], p = 0.031). The total time with turning compliance was significantly different in the intervention group vs. control group (67% vs 54%; difference 0.11, 95%CI [0.08, 0.13], p < 0.001). Turning magnitude (21°, p = 0.923) and adequate depressurization time (39%, p = 0.145) were not statistically different between groups. CONCLUSIONS AND RELEVANCE: Among acutely ill adult patients requiring Intensive Care Unit admission, the provision of optimal turning was greater with a wearable patient sensor, increasing the total time with turning compliance and demonstrated a statistically significant protective effect against the development of hospital acquired pressure injuries. These are the first quantitative data on turn quality in the Intensive Care Unit and highlight the need to reinforce optimal turning practices. Additional clinical trials leveraging technologies like wearable sensors are needed to establish the appropriate frequency and dosing of individualized turning protocols to prevent pressure injuries in at-risk hospitalized patients.
