An association between deep sedation and adverse short-term outcomes has been demonstrated although this evidence has been inconsistent. The A2B (alpha-2 agonists for sedation in critical care) sedation trial is designed to determine whether the alpha-2 agonists clonidine and dexmedetomidine, compared with usual care, are clinically and cost-effective. The A2B intervention is a complex intervention conducted in 39 intensive care units (ICUs) in the UK. Multicentre organisational factors, variable cultures, perceptions and practices and the involvement of multiple members of the healthcare team add to the complexity of the A2B trial. From our pretrial contextual exploration it was apparent that routine practices such as type and frequency of pain, agitation and delirium assessment, as well as the common sedative agents used, varied widely across the UK. Anticipated challenges in implementing A2B focused on the impact of usual practice, perceptions of risk, ICU culture, structure and the presence of equipoise. Given this complexity, a process evaluation has been embedded in the A2B trial to uncover factors that could impact successful delivery and explore their impact on intervention delivery and interpretation of outcomes.
This is a mixed-methods process evaluation guided by the A2B intervention logic model. It includes two phases of data collection conducted during and at the end of trial. Data will be collected using a combination of questionnaires, stakeholder interviews and routinely collected trial data. A framework approach will be used to analyse qualitative data with synthesis of data within and across the phases. The nature of the relationship between delivery of the A2B intervention and the trial primary and secondary outcomes will be explored.
All elements of the A2B trial, including the process evaluation, are approved by Scotland A Research Ethics Committee (Ref. 18/SS/0085). Dissemination will be via publications, presentations and media engagement.
Trauma contributes to the greatest loss of disability-adjusted life-years for adolescents and young adults worldwide. In the context of global abdominal trauma, the trauma laparotomy is the most commonly performed operation. Variation likely exists in how these patients are managed and their subsequent outcomes, yet very little global data on the topic currently exists. The objective of the GOAL-Trauma study is to evaluate both patient and injury factors for those undergoing trauma laparotomy, their clinical management and postoperative outcomes.
We describe a planned prospective multicentre observational cohort study of patients undergoing trauma laparotomy. We will include patients of all ages who present to hospital with a blunt or penetrating injury and undergo a trauma laparotomy within 5 days of presentation to the treating centre. The study will collect system, patient, process and outcome data, following patients up until 30 days postoperatively (or until discharge or death, whichever is first). Our sample size calculation suggests we will need to recruit 552 patients from approximately 150 recruiting centres.
The GOAL-Trauma study will provide a global snapshot of the current management and outcomes for patients undergoing a trauma laparotomy. It will also provide insight into the variation seen in the time delays for receiving care, the disease and patient factors present, and patient outcomes. For current standards of trauma care to be improved worldwide, a greater understanding of the current state of trauma laparotomy care is paramount if appropriate interventions and targets are to be identified and implemented.
To systematically evaluate the effects of quality nursing care on wound pain and anxiety in burn patients. Computerised searches of PubMed, Google Scholar, Cochrane Library, Embase, Wanfang, China Biomedical Literature Database and China National Knowledge Infrastructure databases randomised controlled trials (RCTs) on the application of quality nursing care to burn patients were carried out from database inception to October 2023. Literature was screened and evaluated by two researchers based on inclusion and exclusion criteria, and data were extracted from the final included literature. Stata 17.0 software was employed for data analysis. Overall, 15 RCTs and 1115 burn patients were included, including 563 and 552 in the quality care and routine care groups. It was found that, compared with routine care, burn patients who implemented quality care had significantly less wound pain (SMD: −1.79, 95% CI: −2.22 to −1.36, p < 0.001), anxiety (SMD: −2.71. 95% CI: −3.49 to −1.92, p < 0.001) and depression (SMD: −1.74, 95% CI: −2.35 to −1.14, p < 0.001) levels were significantly reduced post-trauma.
Long-term benzodiazepine use is common despite known risks. In the original Eliminating Medications Through Patient Ownership of End Results (EMPOWER) Study set in Canada, patient education led to increased rates of benzodiazepine cessation. We aimed to determine the effectiveness of implementing an adapted EMPOWER quality improvement (QI) initiative in a US-based healthcare system.
We used a pre–post design with a non-randomised control group.
A network of primary care clinics.
Patients with ≥60 days’ supply of benzodiazepines in 6 months and ≥1 risk factor (≥65 years of age, a concurrent high-risk medication prescribed or a diazepam equivalent daily dose ≥10) were eligible.
In March 2022, we engaged 22 primary care physicians (PCPs), and 308 of their patients were mailed an educational brochure, physician letter and flyer detailing benzodiazepine risks; the control group included 4 PCPs and 291 of their patients.
The primary measure was benzodiazepine cessation by 9 months. We used logistic regression and a generalised estimating equations approach to control for clustering by PCP, adjusting for demographics, frailty, number of risk factors, and diagnoses of arthritis, depression, diabetes, falls, and pain.
Patients in the intervention and control groups were comparable across most covariates; however, a greater proportion of intervention patients had pain-related diagnoses and depression. By 9 months, 26% of intervention patients (81 of 308) had discontinued benzodiazepines, compared with 17% (49 of 291) of control patients. Intervention patients had 1.73 greater odds of benzodiazepine discontinuation compared with controls (95% CI: 1.09, 2.75, p=0.02). The unadjusted number needed to treat was 10.5 (95% CI: 6.30, 34.92) and the absolute risk reduction was 0.095 (95% CI: 0.03 to 0.16).
Results from this non-randomised QI initiative indicate that patient education programmes using the EMPOWER brochures have the potential to promote cessation of benzodiazepines in primary care.
The surgical intervention approach to insulinomas in proximity to the main pancreatic duct remains controversial. Standard pancreatic resection is recommended by several guidelines; however, enucleation (EN) still attracts surgeons with less risk of late exocrine/endocrine insufficiency, despite a higher postoperative pancreatic fistula (POPF) rate. Recently, the efficacy and safety of preoperative pancreatic stent placement before the EN have been demonstrated. Thus, a multicentre open-label study is being conducted to evaluate the efficacy and safety of stent placement in improving the outcome of EN of insulinomas in proximity to the main pancreatic duct.
This is a prospective, randomised, open-label, superiority clinical trial conducted at multiple tertiary centres in China. The major eligibility criterion is the presence of insulinoma located in the head and neck of the pancreas in proximity (≤2 mm) to the main pancreatic duct. Blocked randomisation will be performed to allocate patients into the stent EN group and the direct EN group. Patients in the stent EN group will go through stent placement by the endoscopist within 24 hours before the EN surgery, whereas other patients will receive EN surgery directly. The primary outcome is the assessment of the superiority of stent placement in reducing POPF rate measured by the International Study Group of Pancreatic Surgery standard. Both interventions will be performed in an inpatient setting and regular follow-up will be performed. The primary outcome (POPF rate) will be tested for superiority with the X2 test. The difference in secondary outcomes between the two groups will be analysed using appropriate tests.
The study has been approved by the Peking Union Medical College Hospital Institutional Review Board (K23C0195), Ruijin Hospital Ethics Committee (2023-314), Peking University First Hospital Ethics Committee (2024033-001), Institutional Review Board of Xuanwu Hospital of Capital Medical University (2023223-002), Ethics Committee of the First Affiliated Hospital of Xi’an Jiaotong University (XJTU1AF2023LSK-473), Institutional Review Board of Tongji Medical College Tongji Hospital (TJ-IRB202402059), Ethics Committee of Tongji Medical College Union Hospital (2023-0929) and Shanghai Cancer Center Institutional Review Board (2309282-16). The results of the study will be published in an international peer-reviewed journal.
Diabetic foot ulcers (DFUs) are chronic, difficult-to-heal wounds with a very high incidence of amputation. For patients with DFUs, prevention of amputation is crucial. However, the risk factors associated with DFU amputation and the extent to which different risk factors increase the risk of amputation are still uncertain. This study intends to provide a clinical basis for early intervention in DFU by retrospectively analysing the risk factors for DFU amputation. A retrospective analysis of 200 patients with DFUs admitted between October 2019 and October 2023 was conducted. Sixty-eight of the 200 underwent amputations. The overall amputation rate was 34%. Multiple logistic regression model showed that neutrophil/lymphocyte ratio (OR = 1.943; 95% CI:1.826–2.139), white blood cell (OR = 1.143; 95% CI:1.034–1.267), C-reactive protein (OR = 1.307; 95% CI:1.113–2.194) and Wagner grading (OR = 2.783; 95% CI: 1.751–4.302) were independent risk factors for amputation, while haemoglobin (OR = 0.742; 95% CI:0.638–0.965) and high density lipoprotein were independent protective factors for amputation (OR = 0.168; 95% CI:0.037–0.716), and further Receiver Operating Characteristic Curve curves showed that they showed high accuracy and were good predictors of amputation of DFUs.
Hypertension is a prevalent condition that poses significant challenges in the perioperative management of patients undergoing major non-cardiac surgery, particularly concerning wound healing and scar formation. This meta-analysis assesses the impact of long-term antihypertensive treatment on postoperative wound healing, examining data from seven studies involving patients who received such treatments compared to untreated controls. Our findings reveal that long-term antihypertensive therapy is associated with significantly improved wound healing outcomes, as indicated by lower REEDA scores (I 2 = 96%, SMD = −25.71, 95% CI: [−33.71, −17.70], p < 0.01) 1 week post-surgery and reduced scar formation, demonstrated by lower Manchester Scar Scale scores (I 2 = 93%, SMD = −37.29, 95% CI: [−44.93, −29.64], p < 0.01) 2 months post-surgery. These results underscore the potential benefits of antihypertensive treatment in enhancing surgical recovery and offer insights into optimising perioperative care for hypertensive patients.
Physical frailty (PF) is highly prevalent and associated with undesirable outcomes in stroke survivors aged 65 years or older. However, the long-term trajectories of PF are understudied in those older stroke survivors.
To identify PF trajectories and relative predictors associated with the PF trajectories in older stroke survivors.
This is a secondary analysis of a population-based cohort study in the United States.
Six hundred and sixty-three older stroke survivors from the National Health and Ageing Trends Study from 2015 to 2021 were included. PF was operationally assessed based on the Fried Frailty Phenotype. Trajectories were identified by group-based trajectory modelling. The associations between sociodemographic characteristics, clinical factors, symptoms, cognitive factors and PF trajectories were examined using the design-based logistic regression method.
Most older stroke survivors were 75 and older (63.32%), female (53.99%), white (80.54%) and partnered (50.64%). Two PF trajectory groups were identified (Group 1: low risk, robust; 49.47%; Group 2: high risk, deteriorating; 50.53%). Individuals were at a higher risk to be assigned to Group 2 if they were 75–84 years (adjusted odds ratio [aOR]: 2.16, 95% CI: 1.23–3.80) or 85+ years (aOR: 2.77, 95% CI: 1.52–5.04), had fair self-reported health (aOR: 2.78, 95% CI: 1.53–5.07) or poor self-reported health (aOR: 3.37, 95% CI: 1.51–7.52), had comorbidities (aOR: 8.44, 95% CI: 1.31–54.42), had breathing problems (aOR: 2.18, 95% CI: 1.18–4.02) and had balance problems (aOR: 1.70, 95% CI: 1.06–2.73).
PF trajectories in older stroke survivors were heterogeneous and were associated with age, self-rated health status, comorbidities, breathing problems and balance problems.
Early, routine, dynamic screening for stroke-related physical frailty (PF) and relative predictors might be beneficial for identifying the most vulnerable individuals. Our findings might help develop strategies to manage PF progression.
The reporting followed the STROBE guideline.
The aim of this scoping review was to provide an overview of current research into topical oxygen therapies including the under-researched singlet oxygen for wound healing. A scoping review was undertaken using five databases. After duplicates and ineligible studies were excluded, 49 studies were included for a narrative review. Out of the included 49 studies, 45 (91.8%) were published in the past 10 years (2013–2023) with 32 (65.3%) published in the past 5 years (2018–2023). Eight of the studies were systematic reviews and/or meta-analysis and 18 were RCTs. The search identified zero human RCTs on singlet oxygen, but one human cohort study and five studies in animals. There is evidence that topical oxygen therapy may be useful for the treatment of chronic wounds, mainly diabetic foot ulcers. Singlet oxygen has shown potential, but would need further confirmation in controlled human trials, including more research to understand the bio-properties.
Diabetic Foot Ulcers (DFUs) are a major complication of diabetes, often leading to amputation. Understanding the relationship between haematological inflammatory markers and the incidence of amputation in DFU patients with infectious complications is crucial for improving management and outcomes. This retrospective study, conducted from May 2020 to October 2022, involved 109 patients with DFUs, categorised into amputation (AM) and non-amputation (NAM) groups. Patients were evaluated for various factors, including demographic data, DFU duration, and blood parameters such as haemoglobin A1c (HbA1c), haemoglobin (Hb), albumin (ALB), white blood cell count (WBC), erythrocyte sedimentation rate (ESR), procalcitonin (PCT), C-reactive protein (CRP), platelet-to-lymphocyte ratio (PLR), neutrophil-to-lymphocyte ratio (NLR), and lymphocyte-to-monocyte ratio (LMR). Statistical analyses were performed using independent sample t-tests, Mann–Whitney U test and logistic regression. The univariate analysis showed no significant difference in BMI, DM duration or DFU duration between groups. However, significant differences were noted in PCT, Hb, ESR, ALB, HbA1c and WBC levels, and in inflammatory ratios (NLR, PLR and LMR). Multivariate logistic regression identified CRP, NLR and PLR as independent risk factors for amputation. The study highlights CRP, PLR and NLR as key independent risk factors for amputation in patients with DFUs. These easily obtainable markers from routine blood tests can effectively aid in predicting the risk of osteomyelitis and amputation, enhancing clinical decision making and patient care strategies.
To examine symptoms of depression and generalised anxiety among nurses over 2 years during the pandemic and compare them to the general population.
The COVID-19 pandemic has led to a significant increase in mental stress among the population worldwide. Nursing staff have been identified as being under remarkable strain.
A multicentre prospective longitudinal study.
Symptoms of depression and generalised anxiety in 507 nurses were examined at four different time points (T1: April–July 2020, T2: November 2020–January 2021, T3: May–July 2021, T4: February–May 2022). Results were compared with values of the German general population, presence of gender-specific differences was analysed and frequencies of clinically relevant levels of depression and anxiety were determined.
Throughout the study (T1–T4), a significant increase in depressive and anxiety symptoms was observed. At all four measurement time points, nurses showed significantly higher prevalence for depression and anxiety compared to the German general population. No significant gender differences were found. Frequencies for probable depression and generalised anxiety disorder among nurses were: 21.6% and 18.5% (T1), 31.4% and 29.2% (T2), 29.5% and 26.2% (T3), 33.7% and 26.4% (T4).
During the pandemic, symptoms of depression and generalised anxiety among nurses increased significantly and remained elevated. Their symptom levels were permanently higher than in the general population. These findings strongly suggest that the circumstances of the pandemic severely affected nurses´ mental health.
The COVID-19 pandemic caused a great mental strain on caregivers. This study was able to demonstrate the significant increase in depression and anxiety among nurses during the pandemic. It highlights the urgent need for prevention, screening and support systems in hospitals.
Supportive programmes and preventive services should be developed, not least to prevent the growing shortage of nurses in the health care systems.
The study adhered to relevant EQUATOR guidelines. The STROBE checklist for cohort study was used as the reporting method.
Five hundred and seven nurses completed the questionnaire and provided data for analysis.
The study was registered with the German Clinical Trials Register (https://drks.de/search/en) under the following ID: DRKS00021268.
To characterise subphenotypes of self-reported symptoms and outcomes (SRSOs) in postacute sequelae of COVID-19 (PASC).
Prospective, observational cohort study of subjects with PASC.
Academic tertiary centre from five clinical referral sources.
Adults with COVID-19 ≥20 days before enrolment and presence of any new self-reported symptoms following COVID-19.
We collected data on clinical variables and SRSOs via structured telephone interviews and performed standardised assessments with validated clinical numerical scales to capture psychological symptoms, neurocognitive functioning and cardiopulmonary function. We collected saliva and stool samples for quantification of SARS-CoV-2 RNA via quantitative PCR.
Description of PASC SRSOs burden and duration, derivation of distinct PASC subphenotypes via latent class analysis (LCA) and relationship with viral load.
We analysed baseline data for 214 individuals with a study visit at a median of 197.5 days after COVID-19 diagnosis. Participants reported ever having a median of 9/16 symptoms (IQR 6–11) after acute COVID-19, with muscle-aches, dyspnoea and headache being the most common. Fatigue, cognitive impairment and dyspnoea were experienced for a longer time. Participants had a lower burden of active symptoms (median 3 (1–6)) than those ever experienced (p
We identified three distinct PASC subphenotypes. We highlight that although most symptoms progressively resolve, specific PASC subpopulations are impacted by either high burden of constitutional symptoms or persistent olfactory/gustatory dysfunction, requiring prospective identification and targeted preventive or therapeutic interventions.
Mental health and well-being of healthcare staff were majorly impacted by the COVID-19 pandemic. Little attention has been devoted to the role employers could choose to play in mitigating long-term negative consequences and how effective organisational measures taken were perceived by the individual healthcare workers. This study aims to investigate (1) whether and how healthcare professionals’ mental health has changed from the second to the third pandemic year, (2) whether differences between professional groups (physicians, nurses, paramedics) identified in previous studies persisted and (3) how job demands and resources, for example, work culture and employers’ measures, impacted this situation.
The study employs an observational, cross-sectional design, using an online survey.
The study was conducted online from mid-June to mid-August 2022 among healthcare staff in state-run and private healthcare facilities, such as doctor’s practices, hospitals and paramedic organisations, in Germany and Austria (n=421).
We measured psychological strain using an ICD-10-based symptom checklist, as well as subjective strain and importance of stressors using self-report questions. The ICD-10 was the 10th version of the International Statistical Classification of Diseases and Related Health Problems, a widely used standardized diagnostic manual.
Psychological strain stayed relatively consistent, with nursing staff suffering the most. While the job demands participants felt most affected by were structural issues (eg, staff shortages), employers were far more likely to be perceived as taking action against pandemic-specific job demands (eg, lack of protective gear). Psychological strain was lowest when staff perceived employers’ actions as effective. Only 60% of those with severe enough symptoms to require psychological help had intentions of seeking such help, which is in line with past studies. This help-seeking hesitancy was also dependent on different facets of perceived work culture.
Healthcare staff and nursing staff in particular continue to suffer in the aftermath of the COVID-19 pandemic. However, while employers were perceived as taking action against pandemic-specific job demands, pre-existing job demands causing stress and psychological strain for staff have remained uncombatted.
Sleep disturbance is highly prevalent among post-operative cardiac patients, with negative impacts on surgical recovery and rehabilitation. Post-operative pain and anxiety commonly seen in cardiac surgery patients are associated with poor sleep. Sleep medications commonly used are not ideal with prolonged usage, and non-pharmacological interventions can be good alternatives or complements.
To examine effectiveness of non-pharmacological interventions in post-operative cardiac settings on sleep quality, pain intensity and anxiety.
Systematic review and meta-analysis.
PubMed, CENTRAL, Embase, CINAHL, Scopus, CNKI and ProQuest Dissertations and Theses were searched on 12 October 2022. Randomised controlled trials of non-pharmacological interventions examining sleep quality for adult post-operative cardiac patients were included. Included studies were appraised using Cochrane Risk of Bias tool version 1. Meta-analysis was conducted using RevMan version 5.4.1, and heterogeneity was assessed using I 2 statistics and Cochran Q's test.
Eighteen studies involving 1701 participants were identified. Coronary artery bypass graft was most common. Non-pharmacological interventions varied in types and duration. All intervention groups were compared to usual care, placebo, no interventions or active comparators. Statistically significant improvement in sleep quality (SMD = −.91, 95% CI = −1.17 to −.65) was found among intervention groups that explored cognitive behavioural therapy, relaxation techniques, exercise, massage, acupressure, aromatherapy, music, eye mask and earplugs. Pain intensity was reduced (SMD = −.63, 95% CI = −1.05 to −.20) with cognitive behavioural therapy, relaxation techniques, massage, music and eye mask. Anxiety was improved (SMD = −.21, 95% CI = −.38 to −.04) with exercise and music.
The overall use of non-pharmacological interventions can optimise sleep after cardiac surgery. Further research with greater methodological rigour is needed to investigate different intervention-related characteristics while considering potential confounders.
Post-operative cardiac settings can consider incorporating non-pharmacological interventions. Patients and healthcare providers can be better informed about the use of such interventions to improve sleep.

To examine the effectiveness of family-centred interventions among family caregivers.
Family-centred interventions are an emerging form of intervention that can be effective at improving physical and mental health outcomes for patients and family caregivers. To date, no reviews have examined the effectiveness of family-centred interventions for family caregivers.
A systematic review, including a meta-analysis, was conducted according to the Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA 2020) checklist.
Seven English and two Chinese electronic databases were compressively searched from the outset to March 2023. Two researchers independently reviewed the abstracts and full texts, extracted the data and assessed the risk of bias independently by using the Cochrane ‘Risk of bias assessment tool’.
This systematic review and meta-analysis included 20 articles. The results of the meta-analysis showed that family-centred interventions could significantly improve caregiver burden (p=0.003), quality of life (p = 0.007), depression (p = 0.0002), and stress (p < 0.0001) but not anxiety or family functioning. According to our subgroup analysis, the family-centred empowerment model (p = 0.009) was superior to the other family intervention (p=0.004) in reducing caregiver burden. Family-centred interventions are more effective at reducing the burden of caregiving on family caregivers of adolescent patients (SMD=−0.79, 95% CI[−1.22,−0.36], p = 0.0003) than on adult patients (SMD=−0.37, 95% CI [−0.61,−0.12], p = 0.004).
Family-centred interventions could enhance family caregivers’ burden, quality of life, stress and depression but had no significant impact on anxiety or family functioning.
Family-centred interventions have the potential to improve the health status and caregiving burden of family caregivers. Rigorous and high-quality evidence is needed to confirm the long-term effects of these interventions on family caregivers.
The protocol has been registered in the PROSPERO international prospective register of systematic reviews (Protocol registration ID: CRD42023453607).
The early warning scores (EWS), quick Sequential Organ Failure Assessment (qSOFA) and systemic inflammatory response syndrome (SIRS) criteria have been proposed as sepsis screening tools. This review aims to summarise and compare the performance of EWS with the qSOFA and SIRS criteria for predicting sepsis diagnosis and in-hospital mortality in patients with sepsis.
A systematic review with meta-analysis.
Seven databases were searched from January 1, 2016 until March 10, 2022. Study quality was assessed using the Quality Assessment of Diagnostic Accuracy Studies 2 tool. Sensitivity, specificity, likelihood ratios and diagnostic odd ratios were pooled by using the bivariate random effects model. Overall performance was summarised by using the hierarchical summary receiver–operating characteristics curve. This paper adhered to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses of Diagnostic Test Accuracy Studies (PRISMA-DTA) guidelines.
Ten studies involving 52,474 subjects were included in the review. For predicting sepsis diagnosis, the pooled sensitivity of EWS (65%, 95% CI: 55, 75) was similar to SIRS ≥2 (70%, 95% CI: 49, 85) and higher than qSOFA ≥2 (37%, 95% CI: 20, 59). The pooled specificity of EWS (77%, 95% CI: 64, 86) was higher than SIRS ≥2 (62%, 95% CI: 41, 80) but lower than qSOFA ≥2 (94%, 95% CI: 86, 98). Results were similar for the secondary outcome of in-hospital mortality.
Although no one scoring system had both high sensitivity and specificity, the EWS had at least equivalent values in most measures of diagnostic accuracy compared with SIRS or qSOFA.
Healthcare systems in which EWS is already in place should consider whether there is any clinical benefit in adopting qSOFA or SIRS.
This systematic review did not directly involve patient or public contribution to the manuscript.
Many adverse events are identified as nursing-sensitive indicators (NSIs) and have evidence-based care bundles known to reduce risk of occurrence. Kamishibai cards are a tool from the manufacturing industry used for practice auditing and improvements. Use of Kamishibai cards is believed to be common in the healthcare setting, but true evidence-based guidelines do not yet exist to guide their implementation.
The aim of this integrative review was to identify best practices around the implementation of Kamishibai cards in the healthcare setting for improvement in NSI-associated outcomes.
Eleven nurses at three facilities worked through the evidence using the Johns Hopkins Evidence-Based Practice Model.
Ten articles were included for this review. Broad themes included direct observation with non-punitive and timely feedback, clearly visualized results, use of evidence-based care bundles, pre-implementation education, and both leadership and frontline-staff involvement. All facilities showed improvement in NSI-associated outcomes after the implementation of K-cards.
In health care, K-cards can be implemented and designed with additional focus on the bundles of care they are intended to audit and staff support, but further evidence would better define guidelines around implementation.
