RESUMEN

Gorteria diffusa has elaborate petal spots that attract pollinators through sexual deception, but how G. diffusa controls spot development is largely unknown. Here, we investigate how pigmentation is regulated during spot formation. We determined the anthocyanin composition of G. diffusa petals and combined gene expression analysis with protein interaction assays to characterise R2R3-MYBs that likely regulate pigment production in G. diffusa petal spots. We found that cyanidin 3-glucoside pigments G. diffusa ray floret petals. Unlike other petal regions, spots contain a high proportion of malonylated anthocyanin. We identified three subgroup 6 R2R3-MYB transcription factors (GdMYBSG6-1,2,3) that likely activate the production of spot pigmentation. These genes are upregulated in developing spots and induce ectopic anthocyanin production upon heterologous expression in tobacco. Interaction assays suggest that these transcription factors regulate genes encoding three anthocyanin synthesis enzymes. We demonstrate that the elaboration of complex spots in G. diffusa begins with the accumulation of malonylated pigments at the base of ray floret petals, positively regulated by three paralogous R2R3-MYB transcription factors. Our results indicate that the functional diversification of these GdMYBSG6s involved changes in the spatial control of their transcription, and modification of the duration of GdMYBSG6 gene expression contributes towards floral variation within the species.

RESUMEN

BACKGROUND: Peripheral intravenous catheters (PIVCs) are essential for successful administration of intravenous treatments. However, insertion failure and PIVC complications are common and negatively impact patients' health-outcomes and experiences. We aimed to assess whether generic (not condition-specific) quality of life and experience measures were suitable for assessing outcomes and experiences of patients with PIVCs. METHODS: We undertook a secondary analysis of data collected on three existing instruments within a large randomised controlled trial, conducted at two adult tertiary hospitals in Queensland, Australia. Instruments included the EuroQol Five Dimension - Five Level (EQ5D-5L), the Functional Assessment of Chronic Illness Therapy - Treatment Satisfaction - General measure (FACIT-TS-G, eight items), and the Australian Hospital Patient Experience Question Set (AHPEQS, 12 items). Responses were compared against two clinical PIVC outcomes of interest: all-cause failure and multiple insertion attempts. Classic descriptives were reported for ceiling and floor effects. Regression analyses examined validity (discrimination). Standardised response mean and effect size (ES) assessed responsiveness (EQ5D-5L, only). RESULTS: In total, 685 participants completed the EQ5D-5L at insertion and 526 at removal. The FACIT-TS-G was completed by 264 and the AHPEQS by 262 participants. Two FACIT-TS-G items and one AHPEQS item demonstrated ceiling effect. Instruments overall demonstrated poor discrimination, however, all-cause PIVC failure was significantly associated with several individual items in the instruments (e.g., AHPEQS, 'unexpected physical and emotional harm'). EQ5D-5L demonstrated trivial (ES < 0.20) responsiveness. CONCLUSIONS: Initial investigation of an existing health-related quality of life measure (EQ5D-5L) and two patient-reported experience measures (FACIT-TS-G; AHPEQS) suggest they are inadequate (as a summary measure) to assess outcomes and experiences for patients with PIVCs. Reliable instruments are urgently needed to inform quality improvement and benchmark standards of care.

RESUMEN

BACKGROUND: Semi-urgent surgery where surgical intervention is required within 48 h of admission and the patient is medically stable is vulnerable to scheduling delays. Given the challenges in accessing health care, there is a need for a detailed understanding of the factors that impact decisions on scheduling semi-urgent surgeries. AIM: To identify and describe the organisational, departmental and contextual factors that determine healthcare professionals' prioritising patients for semi-urgent surgeries. METHODS: We used the Joanna Briggs Institute guidance for scoping reviews and the Preferred Reporting Items for Systematic Reviews and Meta-Analysis extension for scoping reviews (PRISMA-ScR) checklist. Four online databases were used: EBSCO Academic Search Complete, EBSCO Cumulative Index to Nursing and Allied Health Literature, OVID Embase and EBSCO Medline. Articles were eligible for inclusion if they published in English and focussed on the scheduling of patients for surgery were included. Data were extracted by one author and checked by another and analysed descriptively. Findings were synthesises using the Patterns, Advances, Gaps, Evidence for practice and Research recommendations framework. RESULTS: Twelve articles published between 1999 and 2022 were included. The Patterns, Advances, Gaps, Evidence for practice and Research recommendations framework highlighted themes of emergency surgery scheduling and its impact on operating room utilisation. Gaps in the management of operating room utilisation and the incorporation of semi-urgent surgeries into operating schedules were also identified. Finally, the lack of consensus on the definition of semi-urgent surgery and the parameters used to assign surgical acuity to patients was evident. CONCLUSIONS: This scoping review identified patterns in the scheduling methods, and involvement of key decision makers. Yet there is limited evidence about how key decision makers reach consensus on prioritising patients for semi-urgent surgery and its impact on patient experience. PATIENT OR PUBLIC CONTRIBUTION: No Patient or Public Contribution.

RESUMEN

Oxylipins are produced enzymatically from polyunsaturated fatty acids, are abundant in triglyceride-rich lipoproteins (TGRLs), and mediate inflammatory processes. Inflammation elevates TGRL concentrations, but it is unknown if the fatty acid and oxylipin compositions change. In this study, we investigated the effect of prescription ω-3 acid ethyl esters (P-OM3; 3.4 g/d EPA + DHA) on the lipid response to an endotoxin challenge (lipopolysaccharide; 0.6 ng/kg body weight). Healthy young men (N = 17) were assigned 8-12 weeks of P-OM3 and olive oil control in a randomized order crossover study. Following each treatment period, subjects received endotoxin challenge, and the time-dependent TGRL composition was observed. Postchallenge, arachidonic acid was 16% [95% CI: 4%, 28%] lower than baseline at 8 h with control. P-OM3 increased TGRL ω-3 fatty acids (EPA 24% [15%, 34%]; DHA 14% [5%, 24%]). The timing of ω-6 oxylipin responses differed by class; arachidonic acid-derived alcohols peaked at 2 h, while linoleic acid-derived alcohols peaked at 4 h (pint = 0.006). P-OM3 increased EPA alcohols by 161% [68%, 305%] and DHA epoxides by 178% [47%, 427%] at 4 h compared to control. In conclusion, this study shows that TGRL fatty acid and oxylipin composition changes following endotoxin challenge. P-OM3 alters the TGRL response to endotoxin challenge by increasing availability of ω-3 oxylipins for resolution of the inflammatory response.

RESUMEN

BACKGROUND: Obesity is associated with chronic inflammation and is a risk factor for insufficient milk production. Inflammation-mediated suppression of LPL could inhibit mammary uptake of long-chain fatty acids (LCFAs; >16 carbons). OBJECTIVES: In an ancillary case-control analysis, we investigated whether women with low milk production despite regular breast emptying have elevated inflammation and disrupted transfer of LCFAs from plasma into milk. METHODS: Data and specimens from a low milk supply study and an exclusively breastfeeding control group were analyzed, with milk production measured by 24-h test-weighing at 2-10 wk postpartum. Low milk supply groups were defined as very low (VL; <300 mL/d; n = 23) or moderate (MOD; ≥300 mL/d; n = 20) milk production, and compared with controls (≥699 mL/d; n = 18). Serum and milk fatty acids (weight% of total) were measured by GC, serum and milk TNF-α by ELISA, and serum high-sensitivity C-reactive protein (hsCRP) by clinical analyzer. Group differences were assessed by linear regression models, chi-square exact tests, and Kruskal-Wallis nonparametric tests. RESULTS: VL cases, as compared with MOD cases and controls, had higher prevalence of elevated serum hsCRP (>5 mg/L; 57%, 15%, and 22%, respectively; P = 0.004), detectable milk TNF-α (67%, 32%, and 33%, respectively; P = 0.04), and obesity (78%, 40%, and 22%, respectively; P = 0.003). VL cases had lower mean ± SD LCFAs in milk (60% ± 3%) than MOD cases (65% ± 4%) and controls (66% ± 5%) (P < 0.001). Milk and serum LCFAs were strongly correlated in controls (r = 0.82, P < 0.001), but not in the MOD (r = 0.25, P = 0.30) or VL (r = 0.20, P = 0.41) groups (Pint < 0.001). CONCLUSIONS: Mothers with very low milk production have significantly higher obesity and inflammatory biomarkers, lower LCFAs in milk, and disrupted association between plasma and milk LCFAs. These data support the hypothesis that inflammation disrupts normal mammary gland fatty acid uptake. Further research should address impacts of inflammation and obesity on mammary fatty acid uptake for milk production.

RESUMEN

BACKGROUND: Children with inflammatory bowel disease (IBD) experience extraintestinal side effects including altered body composition, impaired muscle strength, and aerobic capacity. Exercise training may remedy these issues. PURPOSE: To assess the feasibility, safety, participant satisfaction, and efficacy of a training program for youth with IBD. METHODS: Children with IBD completed 16 weeks of training (2 supervised + 1 home sessions per week). Feasibility was assessed by tracking recruitment, adherence, and compliance rates. Safety was assessed by tracking symptoms and adverse events. Posttraining interviews gauged satisfaction. Circulating inflammatory markers, body composition, muscle strength, aerobic fitness, and habitual physical activity were measured at baseline, midtraining (8 wk), and posttraining. RESULTS: Eleven youth were recruited and 10 completed the study. Participants adhered to 28 (1) of 32 prescribed supervised sessions and 8 (4) of 16 prescribed home sessions. There were no adverse events, and overall feedback on training was positive. Posttraining, we observed an increase in lean mass (+2.4 [1.1] kg), bone density (+0.0124 [0.015] g·cm-2), aerobic fitness (+2.8 [5.7] mL·kg LM-1· min-1), and vigorous physical activity levels (+13.09 [8.95] min·h-1) but no change in inflammation or muscle strength. CONCLUSION: Supervised exercise training is feasible, safe, and effective for youth with IBD and should be encouraged.

RESUMEN

AIMS: To assess patients' and nurses' perceptions and experiences of subepidermal moisture scanning acceptability. DESIGN: Descriptive, qualitative, sub-study, embedded within a pilot randomized control trial. METHODS: Ten patients who were in the intervention arm of the pilot trial and 10 registered nurses providing care for these patients on medical-surgical units participated in individual semi-structured interviews. Data were collected from October 2021 to January 2022. Interviews were analysed using inductive qualitative content analysis, and perspectives (patient and nurse), were triangulated. RESULTS: Four categories were found. The first category 'Subepidermal moisture scanning is acceptable as part of care' showed that patients and nurses were willing to use subepidermal moisture scanning and viewed subepidermal moisture scanning as non-burdensome. The category 'Subepidermal moisture scanning may improve pressure injury outcomes' demonstrated that although subepidermal moisture scanning was believed to prevent pressure injuries, more research evidence about its benefits was required. 'Subepidermal moisture scanning augments existing pressure injury prevention practices', the third category, highlighted that subepidermal moisture scanning aligns with current pressure injury prevention practices while making these practices more patient-centred. In the final category, 'Important considerations when making subepidermal moisture scanning routine practice', practical issues were raised relating to training, guidelines, infection control, device availability and patient modesty. CONCLUSION: Our study demonstrates that using subepidermal moisture scanning is acceptable for patients and nurses. Building the evidence base for subepidermal moisture scanning and then addressing practical issues prior to implementation, are important next steps. Our research suggests that subepidermal moisture scanning enhances individualized and patient-centred care, persuasive reasons to continue investigating subepidermal moisture scanning. IMPACT: For an intervention to be successfully implemented it must be both effective and acceptable, however, there is limited evidence of patients' and nurses' views of SEMS acceptability. SEM scanners are acceptable to use in practice for patients and nurses. There are many procedural aspects that need to be considered when using SEMS such as frequency of measurements. This research may have benefit for patients, as SEMS may promote a more individualized and patient-centred approach to pressure injury prevention. Further, these findings can assist researchers, providing justification to proceed with effectiveness research. PATIENT OR PUBLIC CONTRIBUTION: A consumer advisor was involved in study design, interpretation of data and preparation of manuscript.

RESUMEN

OBJECTIVE: It is estimated that one in four postoperative wound complications occur within 14 days of hospital discharge. Some estimate that up to 50% of readmissions are preventable with effective postoperative education and closer follow-up. Providing patients with information enables them to detect when medical intervention may be required. The aim of this study was to describe the content of postoperative wound care education given to patients, and to identify demographic and clinical factors that predict receipt of surgical wound care education across two tertiary hospitals in Queensland, Australia. METHOD: A prospective correlational design using structured observations, field notes and an electronic chart audit was used. A consecutive sample of surgical patients and a convenience sample of nurses were observed during episodes of postoperative wound care. Field notes were documented to gain a nuanced understanding of the wound care education delivered by nurses. Descriptive statistics were used to describe the samples. A multivariate logistic regression model was developed to describe associations between seven predictors: sex; age; case complexity; type of wound; dietetic consult; the number of postoperative days; and receipt of postoperative wound care education. RESULTS: In total, 154 nurses delivering surgical wound care and 257 patients receiving wound care were observed. Across the combined number of patients across the two hospitals, 71/257 (27.6%) wound care episodes included postoperative wound education. The content of the wound care education mainly focused on keeping the wound dressing dry and intact, while the secondary focus was on showing patients how to remove and replace the dressing. In this study, three of the seven predictors were significant: sex (ß=-0.776, p=0.013); hospital site (ß=-0.702, p=0.025); and number of postoperative days (ß=-0.043, p=0.039). Of these, sex was the strongest, with females twice as likely to receive some form of wound care education during the postoperative period. These predictors explained 7.6-10.3% of variance in the postoperative wound care education patients received. CONCLUSION: Further research to develop strategies designed to improve the consistency and comprehensiveness of the postoperative wound care education delivered to patients is needed.

RESUMEN

Surgical wound dehiscence (SWD) is a serious complication-with a 40% estimated mortality rate-that occurs after surgical intervention. Since the implementation of advanced recovery protocols, the current global incidence of SWD is unknown. This systematic review and meta-analysis estimated the worldwide incidence of SWD and explored its associated factors in general surgical patients. Eligible full-text cross-sectional, cohort and observational studies in English, between 1 January 2010 to 23 April 2021, were retrieved from MEDLINE, CINAHL, EMBASE and the Cochrane Library. Data extraction and quality appraisal were undertaken independently by three reviewers. Random effects meta-analytic models were used in the presence of substantial inconsistency. Subgroup, meta-regression and sensitivity analyses were used to explore inconsistency. Publication bias was assessed using Hunter's plots and Egger's regression test. Of 2862 publications retrieved, 27 studies were included in the final analyses. Pooled data from 741,118 patients across 24 studies were meta-analysed. The 30-day cumulative incidence of SWD was 1% (95% Confidence Interval (CI): 1-1%). SWD incidence was highest in hepatobiliary surgery, at 3% (95% CI: 0-8%). Multivariable meta-regression showed SWD was significantly associated with duration of operation and reoperation (F=7.93 (2-10); p=0.009), explaining 58.2% of the variance. Most studies were retrospective, predated the agreed global definition for SWD and measured as a secondary outcome; thus, our results likely underestimate the scope of the problem. Wider uptake of the global definition will inform the SWD surveillance and improve the accuracy of reporting.

RESUMEN

OBJECTIVE: To explore patients' priorities and preferences for optimal care of their acute or hard-to-heal surgical wound(s). METHOD: This qualitative study involved semi-structured individual interviews with patients receiving wound care in Queensland, Australia. Convenience and snowball sampling were used to recruit patients from inpatient and outpatient settings between November 2019 and January 2020. Interviews were audio recorded, transcribed verbatim and analysed using thematic analysis. Emergent themes were discussed by all investigators to ensure consensus. RESULTS: A total of eight patients were interviewed, five of whom were male (average median age: 70.5 years; interquartile range (IQR): 45-80 years). Four interrelated themes emerged from the data that describe the patients' surgical wound journey: experiencing psychological and psychosocial challenges; taking back control by actively engaging in care; seeking out essential clinician attributes; and collaborating with clinicians to enable an individualised approach to their wound care. CONCLUSION: Findings from this study indicate that patients want to actively collaborate with clinicians who have caring qualities, professional skills and knowledge, and be involved in decision-making to ensure care meets their individual needs.

RESUMEN

AIMS: Identify and synthesise the published literature on the approaches and practices nurses use during the delivery of pressure injury prevention (PIP) education to hospitalised medical and surgical patients. DESIGN: An integrated review. METHODS: Whitmore and Knaff's (2005) five-stage methodology guided this review: (1) research problem identification; (2) literature search; (3) data evaluation; (4) data analysis; and (5) results. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (2020) Statement was followed. The quality of included studies was assessed using the Mixed Method Appraisal Tool (2018). Extracted data were analysed using inductive content analysis. DATA SOURCES: Journal publication dates from 1992 to 2022. Systematic searches of CINAHL (Cumulative Index of Nursing and Allied Health Literature) complete, Embase, PsycINFO (via Ovid) and Scopus databases were undertaken. RESULTS: A total of 3892 articles were initially identified, four quantitative and two qualitative studies were included. Articles were published between 2013 and 2022.Two themes were identified: responsibility and workplace culture determine nurses' approach to PIP education delivery; and nurses tailor education strategies to address challenges and opportunities for PIP education delivery. CONCLUSION: Nurses require resources to facilitate approaches to PIP education with medical and surgical patients. In the absence of clear instruction to support nurses' practice, PIP education for patients is at best delivered in an informal and ad hoc manner. Nurses require accessible education resources to enable them to tailor the content and frequency of PIP education to patients in med-surg settings. PATIENT OR PUBLIC CONTRIBUTION: No patient or public contribution.

RESUMEN

BACKGROUND: Some patients at end of life (EOL) develop wounds known as Kennedy terminal ulcers, terminal ulcers, and Skin Changes At Life's End. However, there is ambiguity around the defining wound characteristics of these conditions and a lack of validated clinical assessment tools available to identify them. OBJECTIVE: To gain consensus on the definition and characteristics of EOL wounds and establish the face and content validity of a wound assessment tool for use in adults at EOL. METHODS: Using a reactive online Delphi technique, international wound experts reviewed the 20 items in the tool. Over two iterative rounds, experts assessed item clarity, relevance, and importance using a four-point content validity index. The content validity index scores were calculated for each item, with a level of 0.78 or higher signifying panel consensus. RESULTS: Round 1 included 16 panelists (100.0%). The agreement for item relevance and importance ranged from 0.54% to 0.94%, and item clarity scored between 0.25% and 0.94%. Following round 1, four items were removed, and seven others reworded. Other suggestions included changing the tool name and including Kennedy terminal ulcer, terminal ulcer, and Skin Changes At Life's End in the EOL wound definition. In round 2, the now 13 panel members agreed with the final 16 items included and suggested minor wording changes. CONCLUSIONS: This tool could provide clinicians with an initially validated tool to accurately assess EOL wounds and gather much needed empirical prevalence data. Further research is needed to underpin accurate assessment and the development of evidence-based management strategies.

RESUMEN

BACKGROUND: Subepidermal moisture (SEM) scanning is a novel technology that measures changes in localised oedema. Accumulation of subepidermal oedema is associated with early tissue damage that may lead to a pressure injury. AIM: The primary study objective was to observe the variations in sacral subepidermal oedema levels over a continuous period of 60-degree head of bed elevation positioning. METHODS: Healthy adult participants were recruited in this prospective observational study. Participants were positioned at 60-degree head of bed elevation for 120 min and sacral SEM measurements were collected at baseline and in 20 min increments. RESULTS: A total of 20 participants with a mean age of 39.3 years (SD = 14.7) were recruited. The mean SEM delta value increased 6.3% from 0.46 SEM delta at baseline to 0.49 SEM delta after 120 min, however these differences are not statistically significant (p = .21). There were also no significant findings between SEM delta variations and demographic factors. CONCLUSION: In a sample of healthy individuals, 120 min of continuous loading with a 60-degree head of bed elevation did not lead to a significant change in sacral subepidermal oedema levels. Further research on the response of healthy adult tissue under external forces associated with different angles of head of bed positioning may further contribute to our understanding pressure injury prevention.

RESUMEN

AIM OF THE STUDY: To develop and undertake validation testing of a survey designed to measure patients' experiences of and preferences for surgical wound care discharge education. MATERIALS AND METHODS: A literature review and content analysis was undertaken on patients' experiences of and preferences for surgical wound care discharge education. Four themes were uncovered in the literature (wound care discharge education, preferences for discharge education delivery, participation in wound care decisions and patient ability to manage their surgical wound to prevent wound complications), which guided item generation. Three types of validity testing occurred including: 1) face validity testing by the research team; 2) content validity testing (using Delphi study) with an international panel of experts including patients, clinicians and researchers; and 3) content validity (using pilot-testing) of the survey with seven patients from the target population. RESULTS: Initially 106 items were generated from the literature, and of these, 55 items were subjected to content validity testing by an international panel of 41 experts. After two Delphi rounds, 18 items were retained. Most patients provided limited and very minor feedback during pilot-testing. However, pilot-testing resulted in a revised survey administration plan to deliver the survey via telephone, including adding prompts and preambles to items. CONCLUSION: An 18-item survey comprised of three groups of items and an individual item was rigorously developed. The survey requires further testing among a larger sample of patients to confirm the items reflect important aspects of patients' experiences of and preferences for surgical wound care discharge education.

RESUMEN

Head of bed elevation is used to manage some medical and surgical conditions however this may increase a patient's risk of sacral pressure injuries. Novel point-of-care technologies that measure subepidermal moisture can identify changes in localised subepidermal oedema and potential pressure injury risk. This prospective exploratory study investigated variations in sacral subepidermal oedema in healthy adults during 120-min of 60° head of bed elevation. Sacral subepidermal oedema was measured at 20-min intervals using the Provisio® subepidermal moisture scanner. Descriptive analysis, one-way repeated measures analysis of variance and an independent t-test were conducted. Slightly more male volunteers (n = 11; 55%) were recruited and the sample mean age was 39.3 years (SD 14.7) with an average body mass index of 25.8 (SD 4.3). Little variation in the mean sacral subepidermal moisture of healthy adults was observed. There was a statistically significant difference in the mean sacral subepidermal moisture measurements between males and females (Mean difference 0.18; 95% confidence intervals: 0.02 to 0.35; P = .03). Healthy adults can tolerate prolonged 60° head of bed elevation without developing increased subepidermal sacral oedema. This warrants further investigation in other populations, in various positions and over different time periods.

RESUMEN

The aim of this study was to describe patients' experiences of, and preferences for, surgical wound care discharge education and how these experiences predicted their ability to self-manage their surgical wounds. A telephone survey of 270 surgical patients was conducted across two hospitals two weeks after discharge. Patients preferred verbal (n = 255, 94.8%) and written surgical wound education (n = 178, 66.2%) from medical (n = 229, 85.4%) and nursing staff (n = 211, 78.7%) at discharge. The most frequent education content that patients received was information about follow-up appointments (n = 242, 89.6%) and who to contact in the community with wound care concerns (n = 233, 86.6%). Using logistic regression, patients who perceived that they participated in surgical wound care decisions were 6.5 times more likely to state that they were able to manage their wounds at home. Also, patients who agreed that medical and/or nursing staff discussed wound pain management were 3.1 times more likely to report being able to manage their surgical wounds at home. Only 40% (107/270) of patients actively participated in wound-related decision-making during discharge education. These results uncovered patient preferences, which could be used to optimise discharge education practices. Embedding patient participation into clinical workflows may enhance patients' self-management practices once home.

RESUMEN

INTRODUCTION: Pressure injury (PI) is an ongoing problem for patients in intensive care units (ICUs). The aim of this study was to explore the nature and extent of PI prevention practices in Australian adult ICUs. MATERIALS AND METHODS: An Australian multicentre, cross-sectional study was conducted via telephone interview using a structured survey instrument comprising six categories: workplace demographics, patient assessment, PI prevention strategies, medical devices, skin hygiene, and other health service strategies. Publicly funded adult ICUs, accredited with the College of Intensive Care Medicine, were surveyed. Data were analysed using descriptive statistics and chi-square tests for independence to explore associations according to geographical location. RESULTS: Of the 75 eligible ICUs, 70 responded (93% response rate). PI was considered problematic in two-thirds (68%) of all ICUs. Common PI prevention strategies included risk assessment and visual skin assessment conducted within at least 6 h of admission (70% and 73%, respectively), a structured repositioning regimen (90%), use of barrier products to protect the skin (94%), sacrum or heel prophylactic multilayered silicone foam dressings (88%), regular PI chart audits (96%), and PI quality improvement projects (90%). PI prevention rounding and safety huddles were used in 37% of ICUs, and 31% undertook PI research. Although most ICUs were supported by a facility-wide skin integrity service, it was more common in metropolitan ICUs than in rural and regional ICUs (p < 0.001). Conversely, there was greater involvement of occupational therapists in PI prevention in rural or regional ICUs than in metropolitan ICUs (p = 0.026). DISCUSSION AND CONCLUSION: This is the first study to provide a comprehensive description of PI prevention practices in Australian ICUs. Findings demonstrate that PI prevention practices, although nuanced in some areas to geographical location, are used in multiple and varied ways across ICUs.

RESUMEN

BACKGROUND: Integrated peripheral intravenous catheters (PIVCs) demonstrate clinical efficacy, however, device complexity and design differences may be a potential barrier to implementation. AIMS: To assess nurse acceptability of integrated PIVC systems. METHODS: A cross-sectional survey was nested within a multicentre randomised controlled trial. One hundred nurses caring for patients with integrated and non-integrated PIVCs completed a 17-item survey about key differences between devices (eg function and appearance, perceived patient comfort and skin injuries). FINDINGS: Most nurses reported the integrated PIVC wings prevented device movement (80%), achieved patient comfort in areas of flexion (78%), and no patients developed skin injuries (100%). Nurses rated the ease of accessing and overall confidence using the integrated PIVC as significantly higher than the non-integrated design (P<0.001). CONCLUSION: The integrated PIVC received positive feedback from nurses and had few barriers to implementation.

RESUMEN

OBJECTIVE: The authors identify and synthesize the published primary literature on unavoidable skin breakdown and end-of-life wounds known as terminal ulcers. DATA SOURCES: Sources were identified through a systematic search of the Cochrane Library, Medline, ProQuest, EMBASE, CINAHL complete, and PubMed databases. STUDY SELECTION: The date limiters were set between 1984 and 2020 to locate primary qualitative, quantitative, and/or mixed-methods studies on terminal ulcers. DATA EXTRACTION: Investigators examined 180 sources and ultimately included four quantitative studies in this review. All were conducted in the US and published between 1989 and 2019. Retrospective chart audits of deceased patients' medical files were undertaken in three of the studies, and prospective observations were used in the fourth. DATA SYNTHESIS: Descriptive and inductive content analyses were conducted. Three categories emerged: (1) distinguishing the ulcer development patterns, (2) identifying the ulcer characteristics, and (3) delivering specialized and individualized end-of-life care. CONCLUSIONS: Limited primary evidence has been published on terminal ulcers. Pressure injuries and terminal ulcers have similar appearances, but their development differs significantly. The lack of a specific terminal ulcer assessment tool and staging system increases the risk of these unavoidable end-of-life wounds being incorrectly assessed and managed as pressure injuries. Further research on terminal ulcers is needed to inform clinical practice and ensure specialized care is delivered to patients who develop these wounds.

RESUMEN

BACKGROUND: Prophylactic foam border dressings are recommended for high-risk patients in addition to standard pressure injury prevention protocols despite limited high-quality evidence regarding their effectiveness. This protocol describes the process evaluation that will be undertaken alongside a multisite randomised controlled trial investigating the clinical and cost-effectiveness of these dressings in reducing hospital-acquired sacral pressure injury incidence. METHODS: This theory informed parallel process evaluation using qualitative and quantitative methods will be undertaken in medical and surgical units. To evaluate fidelity, recruitment, reach, dose delivered and received, and context, process data will include: research nurses' self-reported adherence to intervention protocols; semi-structured interviews with participants and research nurses and focus groups with nursing staff; participants' satisfaction and comfort with the dressings and perceived level of participation in pressure injury prevention; and nurses' attitudes toward pressure injury prevention. The proportion of the target population recruited, participant characteristics, and adherence to intervention protocols will be reported using descriptive statistics. Chi square or t-tests will compare differences in demographic characteristics between groups, and non-participants, and multivariate modelling will investigate potential moderators on the trial outcomes. Analysis of qualitative data will be guided by the Framework Method, which provides a clear, systematic process for developing themes. DISCUSSION: This process evaluation will provide valuable insights into mechanisms of impact and contextual and moderating factors influencing trial outcomes. Process data will enhance reproducibility of the intervention and trustworthiness of findings, and inform clinicians, researchers, and policy makers about the extent to which foam border dressings can be feasibly implemented in clinical practice.
