The purpose of this review is to identify the theoretical framework of implementation science in the intensive care unit (ICU), the determinants affecting implementation results, the intervention guided by a theoretical framework and the assessment of implementation effectiveness based on implementation science to guide further advancement of the implementation of evidence in the field of ICU.

The scoping review was conducted in accordance with the Joanna Briggs Institute (JBI) Scoping Review Methodology Group’s guidance and reported following Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews guidelines. The study protocol was registered with the International Prospective Registry of Systematic Reviews on 15 December 2024 (registration number: CRD42024614246).

We searched the following databases and sources: PubMed, Web of Science, Cochrane Library and EBSCO.

We included studies exploring the implementation science in the ICU that were published in English language.

Two researchers conducted the literature search by referring to the search strategies, and one researcher removed duplicates using EndNote. Two independent investigators screened the retrieved studies based on their titles and abstracts using eligibility criteria. Subsequently, the same two researchers conducted a full-text screening.

13 articles were included: 8 qualitative studies, 3 mixed studies, 1 quasi-experimental study and 1 prospective observational study. Regarding the implementation of the theoretical framework for research, seven studies applied the consolidated framework for implementation research (CFIR), two studies applied the research implementation in health services framework (i-PARIHS) and one each of the research into the translating research into practice model, the exploration, preparation, implementation, sustain, the reach, effectiveness, adoption, implementation and maintenance model and the behaviour change wheel. The CFIR was the most applied in the ICU, followed by the i-PARIHS. The literature demonstrated how implementation science is used and how it can reduce the gap between evidence and practice.

Strategies to support the implementation of accelerated evidence-based practice in the ICU are important, and more researchers need to conduct implementation science studies of the ICU to facilitate the translation of evidence and improve the quality of nursing practice in the future.

Human papillomavirus (HPV) affects nearly 85% of sexually active adults during their lifetime and is responsible for HPV-related cancers in both males and females. Although the HPV vaccine can prevent up to 90% of these cancers, vaccination rates remain low, particularly among college students. Recently, video has emerged as a powerful intervention for shaping public opinion and behaviour toward health-related topics; however, most interventions have primarily focused on adolescents, their parents and females. The primary objective of this study is to develop a video-based intervention, informed by input from a diverse group of stakeholders and evaluate its preliminary effectiveness in promoting HPV vaccination intention, attitudes toward vaccination, subjective norms, perceived behavioural control (PBC) and uptake of the first HPV vaccine dose among college students through a randomised controlled trial (RCT).

The study is guided by the Theory of Planned Behaviour. A Student Advisory Board of eight college students was established to provide insights and guidance across all phases, including the co-development of HPV and HPV vaccine-related videos with faculty mentors. A pilot RCT will then be conducted in which participants in the intervention group view the stakeholder-created videos, while those in the control group watch four Centers for Disease Control and Prevention (CDC)-based videos of comparable length and content. The effectiveness of the videos will be compared by measuring participants’ intentions, attitudes, subjective norms and PBC regarding the HPV vaccine between the intervention and control groups at baseline, immediately after the intervention and 2 months after implementing the intervention. The uptake of the first dose of the HPV vaccine will be assessed at the 2-month time point. Moderators, including message fatigue and processing fluency, participants’ satisfaction and intervention dose as well as confounding variables such as provider recommendation and encouragement will also be measured. A research team member responsible for data management and analysis will be blinded to the study condition/group allocation, while another team member will send reminder texts.

Ethical approval from the Michigan State University’s Biomedical and Health Institutional Review Board has been obtained (Study ID: STUDY00010264). The results will be disseminated to the broader public through public forums, social media and seminars organised by the college health centre, community resource centre and local health departments. Additionally, the findings will be shared with healthcare professionals through professional training and meetings, and with researchers via conferences and publications.

To develop and validate a predictive model for assessing in-hospital mortality in patients with intra-abdominal sepsis (IAS), a leading cause of sepsis.

Secondary analysis of two retrospective critical care databases.

Data extracted from the Intensive Care Medicine Information Marketplace IV (MIMIC-IV) and the eICU Collaborative Research Database.

Patients with IAS from MIMIC-IV (2008–2019; 1300 patients, 264 deaths) for model training and internal validation, and eICU (2014–2015; 149 patients, 33 deaths) for external validation.

Clinical data were used for constructing a predictive model. Variable selection was performed using least absolute shrinkage and selection operator regression, followed by model development with multivariable logistic regression. The model was visualised as a nomogram.

The primary outcome was in-hospital mortality. Secondary outcomes were model performance metrics, including the area under the receiver operating characteristic curve (AUC), calibration curves, decision curve analysis and clinical impact curves.

Six predictors (lactate, age, activated partial thromboplastin time, blood urea nitrogen, total bilirubin and platelets) were identified. The predictive model showed good performance with an AUC of 0.795 (95% CI 0.758 to 0.831) in the training set (n=910) and 0.846 (95% CI 0.772 to 0.919) in the external validation set (n=149).

A robust predictive model was developed to estimate the risk of in-hospital mortality in patients with IAS. This tool may assist clinicians in enhancing patient management and decision-making.

Many patients who are extubated after receiving mechanical ventilation for acute respiratory failure experience extubation failure (ie, require reintubation hours to days after extubation). High-quality evidence shows that extubating patients directly to non-invasive ventilation (NIV) or high-flow nasal cannula oxygen (HFNC), rather than conventional low-flow oxygen, can prevent extubation failure. These guideline-recommended interventions, however, require care coordination involving multiple intensive care unit (ICU) team members and are infrequently used. Interprofessional education (IPE), which teaches members of multiple professions together, could effectively address this implementation gap in complex, team-based, critical care settings, particularly when paired with a customisable protocol.

This batched, stepped-wedge, cluster-randomised, type 2 hybrid effectiveness–implementation trial will test three hypotheses: (1) when compared with traditional online education (OE), IPE increases implementation of preventive postextubation respiratory support, (2) the benefits of IPE are increased when paired with a clinical protocol and (3) preventive postextubation NIV for high-risk patients and preventive postextubation HFNC for low-risk patients reduce in-hospital mortality when compared with conventional postextubation oxygen therapy. The trial will recruit 24 clusters made up of one or more ICUs that care for at least 100 mechanically ventilated patients per year in a large multihospital health system in the USA. All clusters will receive OE, IPE and a clinical protocol, with timing determined by randomisation. We will also randomise half of the clusters to education promoting postextubation NIV for patients at high risk of extubation failure and preventive, postextubation HFNC for patients at lower risk, whereas the other half will be randomised to education promoting postextubation HFNC for all eligible patients. We will include all patients who are invasively mechanically ventilated for at least 24 hours. The primary implementation endpoint is the rate of use of postextubation NIV or HFNC among eligible participants. The primary clinical endpoint is in-hospital mortality truncated at 60 days from intubation.

This study was approved by the institutional review board of the University of Pittsburgh and an independent data safety monitoring board. We describe the methods herein using the Standard Protocol Items for Randomised Trials framework and discuss key design decisions. We will disseminate results to participating healthcare providers, through publication in a peer-reviewed medical journal and via presentations at international conferences.

We aimed to understand the factors affecting psychological well-being of patients undergoing haemodialysis (HD). First, we explored how physical symptom severity, emotional distress and social support influence psychological well-being. Second, we examined the impact of different types of social support. Third, we investigated whether any variables mediate the relationship with psychological well-being.

A cross-sectional study, a type of observational design, was conducted on patients at a medical centre in Taiwan in 2020.

A total of 117 outpatients who had undergone regular HD for at least 3 months were enrolled.

The psychological well-being was assessed through self-report questionnaires.

We found that emotional distress (β=–0.25, p=0.033) had a significant negative impact on psychological well-being. However, the presence of appraisal support mitigated this effect. Specifically, appraisal support fully mediated the adverse impact of emotional distress on psychological well-being. In addition, the severity of physical symptoms was generally mild and did not influence psychological well-being.

Receiving appraisal support from family, friends and healthcare professionals not only alleviates emotional distress but also enhances psychological well-being both directly and indirectly among patients undergoing HD. Healthcare professionals should address issues of personal importance while serving as consultants, educators and evaluators to support patients in managing their chronic condition.

Human papillomavirus (HPV) is a major global health concern linked to cancers. Although a safe and effective vaccine exists, HPV vaccination rates are still low among Asian American and Pacific Islander (AAPI) populations. Barriers such as limited awareness, cultural stigma and systemic inequities contribute to this gap. This systematic review and meta-analysis aims to compile current evidence on HPV vaccination behaviours and related factors among AAPIs to help develop culturally tailored interventions and public health strategies.

This review will include descriptive and correlational studies (quantitative, qualitative and mixed methods), examining HPV vaccination intention or uptake among AAPI populations in the USA from inception to December 2024. Randomised controlled trials and intervention studies will be excluded. Databases to be searched include PubMed, CINAHL, PsycINFO and Cochrane. Study screening, data extraction and quality assessment will be conducted independently by three reviewers using standardised tools. Risk of bias in non-randomised studies will be assessed using Risk Of Bias In Non-randomised Studies of Interventions (ROBINS-I), and the Critical Appraisal Skills Programme (CASP) checklist will be used for qualitative studies. Quantitative findings will be synthesised narratively and, where appropriate, through meta-analysis using random-effects models. Qualitative themes will be synthesised to contextualise quantitative results.

Ethics approval is not required for this protocol as it does not involve primary data collection. Findings will be disseminated via peer-reviewed publications and conference presentations. Findings of this systematic review and meta-analysis will provide critical insights for promoting HPV vaccination and reducing HPV-related cancer disparities among AAPIs.

Postoperative delirium is a serious complication occurring in 10.09%–51.28% of geriatric patients undergoing surgery for hip fractures. Delirium has resulted in poorer functional recovery, increased readmission rates, repeat surgeries and elevated mortality. Perioperative music listening is a promising non-pharmacological intervention with beneficial effects on delirium. This trial aims to evaluate the effect of perioperative music listening on postoperative delirium in patients with femur fracture undergoing surgery.

The music listening on clinical outcome after hip fracture operations study is an investigator-initiated, randomised controlled, clinical trial. 102 patients with femur fracture meeting eligibility criteria will be randomised to the music listening intervention or control group with concealed allocation. The perioperative music intervention consists of preselected lists totalling 4 hours of music (classical, jazz and pop). The primary outcome is postoperative delirium rate. Secondary outcome measures include pain score and opioid medication requirement, postoperative complications, hospital length of stay, 14-day readmission rate and 30-day mortality. A 90-day follow-up will be performed in order to assess readmission rate and mortality rate. Data will be analysed according to an intention-to-treat principle.

The study protocol was approved by the Research Ethics Committee of Ditmanson Medical Foundation of Chia-Yi Christian Hospital (IRB2023084). The trial will be carried out following the Declaration of Helsinki principles and Good Clinical Practice guidelines. Research data will be reported following Consolidated Standards of Reporting Trials guidelines and study results will be published in a peer-reviewed journal and presented at scientific conferences. Data availability statement: data generated by this study will be made available on reasonable request. A data sharing plan has been submitted to ClinicalTrials.gov in compliance with ICMJE (International Committee of Medical Journal Editors) and BMJ Open data policies.

Cardiovascular (CV) disease is the leading cause of morbidity and mortality globally. Low-density lipoprotein cholesterol (LDL-C) is an important modifiable risk factor of major adverse cardiovascular events. Patients without prior myocardial infarction (MI) or stroke but with established risk factors and elevated LDL-C may benefit from intensive lipid-lowering therapy (LLT); however, the size and potential healthcare burden of this population globally are not known. The benefits of evolocumab, a proprotein convertase subtilisin/kexin type 9 inhibitor, in these patients, are currently being studied in the phase 3 Effect of Evolocumab in Patients at High Cardiovascular Risk Without Prior Myocardial Infarction or Stroke (VESALIUS-CV) trial. To characterise the high-risk pre–CV-event (VESALIUS-CV–like) individuals in the real world, an observational study is being conducted across multiple countries.

This retrospective cohort study will use a common protocol and an analytical common data model approach to characterise VESALIUS-CV–like individuals in the real world across different geographical regions and healthcare settings. The study period will be from 2010 to 2022, subject to data availability in study sites. Patients aged 50 years and older at high risk of CV disease but without prior MI or stroke will be included in this study. VESALIUS-CV–like individuals are defined through a combination of the following: (1) one diagnosis of coronary artery disease, cerebrovascular disease, peripheral artery disease or diabetes with microvascular complications or chronic insulin use; (2) an elevated LDL-C measurement and (3) other high-risk factors. The objectives of this study are to estimate the prevalence of VESALIUS-CV–like individuals, describe their characteristics and care pathways and estimate their incidence rates of CV events and healthcare costs. The prevalence of VESALIUS-CV–like individuals will be expressed as annual prevalence; patient characteristics at index date will be presented using summary statistics; care pathways will be summarised as LLT prescription across time; and the incidence of defined CV events will be expressed as events per person-years as well as at certain time periods. Healthcare costs will be presented as CV-related costs in different time periods.

Approvals of the study protocol were obtained from relevant local ethics and regulatory frameworks for each participating database. The results of the study will be submitted to peer-reviewed scientific publications and presented at scientific conferences.
