Abstract: Pressure injuries are frequently occurring adverse events in hospitals, negatively impacting patient safety and quality of care. Most pressure injuries are avoidable if effective prevention strategies are used. However, the extent to which various settings influence their use of prevention strategies is unknown. The aim of this study was to describe and compare pressure injury prevention strategies used by medical and surgical nurses in the Chinese context. In this observational study, we used semi‐structured observations with chart audits to collect data in two medical and two surgical wards in a tertiary hospital from June to December 2020. Observations were patient‐focused any prevention practices the patient received were recorded, and a chart audit was used to identify documented prevention strategies. The frequency of each prevention strategy was reported, and differences between medical and surgical wards were analysed using independent t ‐test or χ 2 test. A total of 577 patients (n = 294, 50.9% medical n = 283, 49.1% surgical) were observed and their charts audited. Risk assessment was completed on admission for all patients. Repositioning was the most frequently used strategy, with about 84% (n = 486) patients being repositioned regularly. However, skin care, nutritional risk screening and the use of support surfaces were suboptimal. Patient education was not commonly observed but was documented in 75% (n = 433) of audited charts. More medical patients' skin was kept clean and hydrated, but more surgical patients received barrier creams, had a support surface and received more nutrition support and if a prone position was used, they were more likely to be turned after 2 hr and to be repositioned after sitting in a chair for an hour. Prevention strategies were more likely to be documented in surgical patients' charts. Despite pressure injury prevention guideline recommendations provided various prevention strategies for nurses to apply, the observed use of some strategies such as nutrition, skin care and support surfaces was not ideal. Nurses relied heavily on repositioning for pressure injury prevention. Most pressure injury prevention practices need improvement although surgical patients generally received better preventative care. These findings can facilitate clinicians and nurse managers when tailoring future pressure injury prevention work.

Abstract: Pressure injury is a serious and preventable problem in intensive care units. Translating guidelines into clinical practice can reduce the incidence of pressure injury. Identifying clinical status, barriers and facilitators contribute to guideline implementation. To identify the knowledge, attitudes, and practices of pressure injury prevention in Chinese critical care nurses. Secondary data were extracted from a multicentric clinical trial. Knowledge and attitudes toward pressure injury prevention were assessed by a fourteen‐item questionnaire. The observed practices were recorded using a case report form. The report complies with the STROBE statement. A total of 950 critical care nurses in 15 hospitals from six provinces of China were investigated. A total of 53.1% of nurses received a median score of 6 points or less. Knowledge regarding the repositioning procedure, risk assessment, and heel pressure injury prevention was insufficient. Over 99% of nurses strongly or somewhat agreed that pressure injury prevention was very important and that they were willing to take measures to prevent pressure injury. A total of 27 781 patient days of pressure injury prevention practice were recorded. Repositioning was the most commonly used prevention measure, followed by support surfaces and prophylactic dressings. A combination of repositioning, support surface, and prophylactic dressing was lacking. Chinese critical nurses showed a low level of knowledge and a positive attitude toward pressure injury prevention. Practices of pressure injury prevention were unsatisfactory. There is a clear gap between the guidelines and clinical practices. The barrier (low‐level knowledge) and facilitator (positive attitude) were identified in this study. According to these findings, strategies need to be developed to promote guideline implementation.

Abstract: To explore Registered Nurses' approaches to pressure injury prevention, including how they perceive their roles, how they prioritize pressure injury prevention and factors influencing prevention in the Chinese context. A qualitative descriptive study. Audio‐recorded, face‐to‐face, semi‐structured in idual interviews were conducted with Registered Nurses in a large tertiary hospital in China from August to December 2020. Using the System Engineering Initiative for Patient Safety Model, the interview guide was developed to describe the work system, processes and outcomes (three domains) associated with nurses' pressure injury prevention practices. Deductive and inductive content analyses were used. Twenty‐seven nurses participated in the interviews. Four themes related to two domains of the model emerged: Work system: (i) Nurses lead and coordinate pressure injury prevention Work processes: (ii) In idualized pressure injury prevention is founded on comprehensive patient assessment (iii) Collaborating ensures patients receive appropriate pressure injury prevention and (iv) Competing factors influence the delivery of appropriate pressure injury prevention. One category emerged about work outcome: Nurses strive to do their best in pressure injury prevention but hold major concerns when pressure injuries occur. Nurses play a leading role in pressure injury prevention delivery but require appropriate resources and assistance and support from other healthcare personnel, patients and carers. Understaffing, lack of resources, complex reporting and poor patient compliance challenge nurses in their delivery of pressure injury prevention. Pressure injury prevention is primarily a nursing responsibility therefore nurses' approaches to prevention were explored. Nurses rely on collaboration with others and access to various resources to provide pressure injury prevention. They recognize the patients' and carers' roles and acknowledge the importance of accessing guidance and support from nursing leaders and wound experts. Acknowledging nurses leading role in prevention and ensuring they have adequate resources are important for quality care.

Abstract: Nurses play a vital role in pressure injury prevention (PIP) but require foundational knowledge to ensure appropriate PIP strategies are enacted. To 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. A cross-sectional survey was conducted between June and December 2020. Registered 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. In 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. Knowledge 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.

Abstract: Molecules present a versatile platform for quantum information science 1,2 and are candidates for sensing and computation applications 3,4 . Robust spin-optical interfaces are key to harnessing the quantum resources of materials 5 . To date, carbon-based candidates have been non-luminescent 6,7 , which prevents optical readout via emission. Here we report organic molecules showing both efficient luminescence and near-unity generation yield of excited states with spin multiplicity S 1. This was achieved by designing an energy resonance between emissive doublet and triplet levels, here on covalently coupled tris(2,4,6-trichlorophenyl) methyl-carbazole radicals and anthracene. We observed that the doublet photoexcitation delocalized onto the linked acene within a few picoseconds and subsequently evolved to a pure high-spin state (quartet for monoradical, quintet for biradical) of mixed radical–triplet character near 1.8 eV. These high-spin states are coherently addressable with microwaves even at 295 K, with optical readout enabled by reverse intersystem crossing to emissive states. Furthermore, for the biradical, on return to the ground state the previously uncorrelated radical spins either side of the anthracene shows strong spin correlation. Our approach simultaneously supports a high efficiency of initialization, spin manipulations and light-based readout at room temperature. The integration of luminescence and high-spin states creates an organic materials platform for emerging quantum technologies.
