Effectiveness and safety of metoclopramide in treatment of intractable hiccup: a protocol of systematic review and meta-analysis

Introduction
Hiccup is a common disease that not only occurred on adults but also on infants, which can severely do harm to patients’ physical and psychological health. Metoclopramide has been reported to have effects on intractable hiccup. However, there is a limited evidence that describes the efficacy and safety of metoclopramide in the treatment of intractable hiccup. The aim of this article is to obtain evidence on the effectiveness and safety of metoclopramide in treating patients with intractable hiccup.

Methods and analysis
We will search the following databases, including PubMed, Cochrane Library, Embase, Web of Science, CBM, Wan-fang, VIP database, CNKI and MEDLINE from their inception to 11 November 2021. All the randomised controlled trials associated with metoclopramide in treating intractable hiccup will be included. Articles screened, selected and extracted will be performed by two researchers independently. The risk of bias will be assessed by using the Cochrane Collaboration. We will carry out the meta-analysis by using RevMan V.5.4 software.

Effect of family-centred care on parental mental health and parent-infant interactions for preterm infants: a systematic review protocol

Introduction
Unexpected premature delivery and separation from preterm infants are common problems that parents of preterm infants must handle with. Parents of preterm infants may suffer from severe psychological distress. Family-centred care (FCC) can effectively ease parents’ psychological distress and strengthen connections between parents and their preterm infants. The purpose of this systematic review will be to systematically review and evaluate the impacts of FCC interventions on the mental health of parents of preterm infants and the parent–infant relationship.

Methods and analysis
This protocol for this systematic review will be conducted in line with the Preferred Reporting Items for Systematic Reviews and Meta-Analysis Protocol. We will search databases including PubMed, Embase, The Cochrane Library, CINAHL, Web of Science, PsycINFO, Scopus and ProQuest, CNKI, SinoMed and Wanfang Data from 1 July 2012 to 1 July 2022. An additional search of OpenGrey will be conducted to identify grey literature. Randomised controlled trials related to FCC inventions for preterm infants≤37 weeks’ gestational age and their parents will be included, and the outcome measures will be parental mental health and parent–infant interaction. Two reviewers will independently conduct title and abstract screening, full-text screening, data extraction and study quality assessment. Risk of bias for the studies will be evaluated using the Cochrane Collaboration Risk of Bias V.2.0. Any disagreements will be solved by a third reviewer to reach a consensus. If appropriate, a meta-analysis will be conducted to assess the effect of FCC on parental mental health and parent–infant relationship.

Ethics and dissemination
Research ethics approval will not be required for this review since it will not involve the collection of primary data and will only use published literature. The results will be disseminated in a peer-reviewed journal through publication or by presentation at relevant academic conference.

Prevalence of medically unexplained symptoms in adults who are high users of healthcare services and magnitude of associated costs: a systematic review

Introduction
Medically unexplained symptoms (MUS) is a common clinical syndrome in primary and secondary healthcare service. Outcomes for patients with persistent MUS include increased disability, poorer quality of life and higher healthcare costs. The aim of this systematic review was to determine the prevalence of MUS in patients who are high users of healthcare or high-cost patients in comparison with routine users and the magnitude of associated costs.

Design
A systematic review of the available literature.

Data sources and eligibility criteria
The following electronic databases were systematically searched without language restriction from inception to June 2018 and updated on 22 October 2021: MEDLINE, PsycINFO, EMBASE, CINAHL and PROSPERO. Inclusion criteria included studies investigating adults aged ≥18 years, who were high healthcare users or accrued high healthcare costs, in which the prevalence and/or associated costs of MUS was quantified. Two reviewers independently extracted information on study characteristics, exposure and outcomes.

Results
From 5622 identified publications, 25 studies from 9 countries involving 31 650 patients were selected for inclusion. Due to high risk of bias in many studies and heterogeneity between studies, results are described narratively. There were wide variations in prevalence estimates for MUS in high users of healthcare (2.9%–76%), but MUS was more prevalent in high use groups compared with low use groups in all but one of the 12 studies that included a comparator group. Only three studies investigated healthcare costs associated with MUS, and all three reported greater healthcare costs associated with MUS.

Conclusion
MUS has been found to be more prevalent in high use healthcare populations than comparator groups, but the magnitude of difference is difficult to estimate due to considerable heterogeneity between studies and potential for bias. Future studies should prioritise a standardised approach to this research area, with agreed definitions of MUS and high healthcare use.

Strategies for engaging senior citizens and their informal caregivers in health policy development: a scoping review protocol

Introduction
Care for senior citizens is a global policy issue. There has been limited focus on senior citizen and informal caregiver engagement in policy development. Encouraging senior citizen participation through active engagement in the policymaking process enhances the provision of better services and the creation of responsive policies and is critical to better healthcare. Accordingly, this review aims to map the available evidence to provide an overview of strategies for engaging senior citizens and informal caregivers in health policy development.

Methods and analysis
A scoping review will be conducted. This study will use the updated methodological guidance for conducting a scoping review developed by the Joanna Briggs Institute. This review aims to answer the question: ‘What is known in the literature about strategies for engaging senior citizens and informal caregivers in health policy development?’ Titles and abstracts will be screened to determine eligibility for full-text review based on already established eligibility criteria. Data will be extracted from relevant articles. A summary of extracted data will be presented. The results will be interpreted within the Multidimensional Framework for Patient and Family Engagement in Health and Healthcare.

Ethics and dissemination
Ethical review is not required as scoping reviews are a form of secondary data analysis that synthesises data from publicly available sources. Findings from this proposed review will be disseminated in conferences and to the global scientific community through published academic papers in reputable health policy-related journals.

Effectiveness and feasibility of telerehabilitation in patients with COVID-19: a systematic review and meta-analysis

Objectives
To determine the pooled effectiveness and feasibility of telerehabilitation in patients with COVID-19.

Design
Systematic review and meta-analysis of randomised controlled trials (RCTs).

Data sources
PubMed, CINAHL, Science Direct, PEDro, Google Scholar and Cochrane Library databases were systematically searched to the end of March 2022.

Eligibility criteria and outcomes
RCTs investigating the effects of telerehabilitation in the management of patients with COVID-19 were included. The outcomes of interest were functional capacity, cardiopulmonary exercise tests, quality of life and other variables where data are available.

Data extraction and synthesis
Two reviewers screened, extracted data and performed methodological quality assessment independently. The revised Cochrane Risk of Bias tool was used to assess the risk of bias. Review Manager V.5.4 and Stata V.14.0 software were used for statistical analysis. Mean difference (MD) with 95% CI and the corresponding p value were used to determine the treatment effect between groups. A fixed-effect model was used for all variables as no significant heterogeneity was observed.

Results
Four studies with 334 patients with COVID-19 were included. The pooled result of telerehabilitation showed statistically significant improvement on 6-minute walking test (MD 75.50; 95% CI 54.69 to 96.30; p=0.48), 30-second sit-to-stand test (MD 1.76; 95% CI 1.47 to 2.04; p=0.30), Borg Scale (MD 2.49; 95% CI 2.16 to 2.83; p=0.28) and level of dyspnoea (MD 6.26; 95% CI 5.42 to 7.10; p=0.66). The overall treatment completion rate was 88.46%, and the most common reason for withdrawal after randomisation was lost to follow-up or uncooperativeness.

Conclusions
The findings showed that telerehabilitation interventions could improve functional capacity and exercise perception among patients affected by COVID-19 and can be implemented with a high completion rate and minimal adverse events. However, more studies are required to investigate the effects on cardiopulmonary function, quality of life, anxiety, depression and other variables.

Measuring negative emotional responses to climate change among young people in survey research: a systematic review protocol

Introduction
Many young people report experiencing negative emotional responses to their awareness of climate change and the threats it poses to their future. With that, an increasing number of survey instruments have been developed to examine young people’s negative emotional responses to their awareness of climate change. This report describes a protocol for a systematic review that aims to identify, synthesise and critically appraise how negative emotional responses to climate change among young people have been measured in survey research. The research questions addressed in this review are: (1) How has negative emotional responses to climate change been defined and measured among young people? (2) How do survey instruments measuring young people’s negative emotional responses to climate change vary in terms of reliability and validity? (3) What factors are associated with negative emotional responses to climate change among young people?

Methods and analysis
Seven academic databases (CINAHL, ERIC, MEDLINE, PsycINFO, Web of Science, Scopus, and Environment Complete) will be searched to retrieve studies published between 1 January 2006 and 31 March 2022 and published in English. Studies including survey instruments that measure negative emotional responses among young people (aged 10–24 years) will be eligible for inclusion. Targeted journals will be hand-searched. This review will follow Preferred Reporting Items for Systematic Reviews and Meta-Analyses 2020 guidelines for systematic reviews. The methodological quality, in terms of reliability and validity, of the included studies will be assessed using the Consensus-based Standards for the Selection of Health Measurement Instruments (COSMIN) checklist for risk of bias of patient-reported outcome measures. To rate the quality of the instruments, we will use a modified Grading of Recommendations, Assessment, Development and Evaluations technique defined by the COSMIN guidelines.

Ethics and dissemination
Ethical approval is not applicable for this study. We will disseminate the findings through publication in peer-reviewed journals and presentations.

Entrustable professional activities in nursing education: a scoping review protocol

Introduction
Entrustable professional activities were introduced in medical education more than 15 years ago. EPAs define units of professional practice that can be fully entrusted to sufficiently competent professionals. Today, EPAs have been developed and implemented in many health professions, as the concept is useful in bridging the gap between competency-based education and the daily tasks health professions have to deal with in the workplace. While some evidence exists in medical education, the role of EPAs in nursing education is not yet fully understood. Therefore, the overall aim of this scoping review is to describe the current body of evidence regarding EPA implementation in nursing education.

Methods and analysis
A two-stage screening process will be used during the search phase, in order to screen retrieved abstracts and titles that focus primarily on the discussion of EPA in nursing education in all languages within the last two decades. The electronic databases, OVID (Embase and PubMed combined) and EBSCOhost (CINHAL and ERIC combined), as well as grey literature will be searched. The search period ranges from 1 January 1995 to 31 December 2021. Data will be extracted according to study design, context (geographical location and type of nursing programme), details of EPAs mentioned (title, specifications, limitations and competency domains), as well as evidence of implementation, outcomes and effect sizes.

Ethics and dissemination
Ethical approval is not required as this review will be using previously collected data. Review findings will be published in a peer-reviewed journal and presented at scientific conferences.

COVID-19 during pregnancy and risk of pregnancy loss (miscarriage or stillbirth): a systematic review protocol

Introduction
The COVID-19 pandemic has led to concerns about potential adverse pregnancy outcomes associated with infection, resulting in intensive research. Numerous studies have attempted to examine whether COVID-19 is associated with an increased risk of pregnancy loss. However, studies and reviews to date have drawn differing conclusions. The aim of this systematic review is to provide a summary of all quantitative research on the relationship between pregnancy loss and COVID-19 infection and, if appropriate, to synthesise the evidence into an overall effect estimate.

Methods and analysis
Three publication databases (Embase, PubMed and Cochrane) and four preprint databases (medRxiv, Lancet Preprint, Gates Open Research and Wellcome Open Research) will be searched. Boolean logic will be used to combine terms associated with pregnancy loss and COVID-19. The population of interest are pregnant women. Retrieved results will be assessed in two phases: (1) abstract screening and (2) full text evaluation. All studies which compare pregnancy loss outcomes in women who had COVID-19 versus those who did not quantitatively will be included. Narrative and non-English studies will be excluded. Two reviewers will screen independently, with results compared and discrepancies resolved by the study team. Study quality and risk of bias will be assessed using a quality appraisal tool. Results will be summarised descriptively and where possible synthesised in a meta-analysis.

Ethics and dissemination
This systematic review requires no ethical approval. This review will be published in a peer-reviewed journal and provide an important update in a rapidly evolving field of research.

Household and area determinants of emergency department attendance and hospitalisation in people with multimorbidity: a systematic review

Objectives
Multimorbidity is one of the greatest challenges facing healthcare internationally. Emergency department (ED) attendance and hospitalisation rates are higher in people with multimorbidity, but most research focuses on associations with individual characteristics, ignoring household or area mediators of service use.

Design
Systematic review reported using the synthesis without meta-analysis framework.

Data sources
Twelve electronic databases (1 January 2000–21 September 2021): MEDLINE/OVID, Embase, Global Health, PsycINFO, ASSIA, CAB Abstracts, Science Citation Index Expanded/ISI Web of Science, Scopus, Cumulative Index to Nursing and Allied Health Literature, Sociological Abstracts, the Cochrane Library, and OpenGrey.

Eligibility criteria
Adults aged ≥16 years, with multimorbidity. Exposure(s) were household and/or area determinants of health. Outcomes were ED attendance and/or hospitalisation. The literature search was limited to publications in English.

Data extraction and synthesis
Independent double screening of titles and abstracts to select relevant full-text studies. Methodological quality was assessed using an adaptation of the Newcastle-Ottawa Quality Assessment Scale tool. Given high study heterogeneity, narrative synthesis was performed.

Results
After deduplication, 10 721 titles and abstracts were screened, and 142 full-text articles were reviewed, of which 10 were eligible for inclusion. In people with multimorbidity, household food insecurity was associated with hospitalisation (OR 1.58 (95% CI 1.06 to 2.36) in concordant multimorbidity). People with multimorbidity living in the most versus least deprived areas attended ED more frequently (8.9% (95% CI 8.6 to 9.1) in most versus 6.3% (95% CI 6.1 to 6.6) in least), had higher rates of hospitalisation (26% in most versus 22% in least), and higher probability of hospitalisation (6.4% (95% CI 5.8 to 7.2) in most versus 4.2% (95% CI 3.8 to 4.7) in least). There was non-conclusive evidence that household income is associated with ED attendance and hospitalisation. No statistically significant relationships were found between marital status, living with others with multimorbidity, or rurality with ED attendance or hospitalisation.

Conclusions
There is some evidence that household and area contexts mediate associations of multimorbidity with ED attendance and hospitalisation, but firm conclusions are constrained by the small number of studies published and study design heterogeneity. Further research is required on large population samples using robust analytical methods.

Systematic review of copper intrauterine contraception continuation in young nulliparous women based on intrauterine device type

Objectives
No copper intrauterine device (IUD) type is known to better suit young nulliparous women who tend to experience higher rates of IUD discontinuation compared with their older parous counterparts. A systematic review to determine which IUDs have higher continuation rates in young nulliparous women was undertaken.

Design
Systematic review and meta-analyses of available evidence based on IUD type.

Data sources
AMED, BNI, CINAHL, DARE, EMBASE, EMCARE, HMIC, MEDLINE, PsycINFO, PubMed, TRIP, and the Cochrane Library electronic databases were searched from inception to 11 May 2022; as well as the Bandolier, Medicines and Healthcare products Regulatory Agency, Faculty of Sexual and Reproductive Healthcare, Royal College of Obstetricians and Gynaecologists, Department of Health, National Institute for Health and Care Excellence, Scottish Intercollegiate Guidelines, WHO and Google Scholar websites.

Eligibility criteria
All studies on IUDs currently available in the UK or comparable (same design and size) to those available in the UK, involving nulliparous women of any age including those aged under 30.

Data extraction and synthesis
Independently extracted data were assessed as low risk of bias using the Mixed Methods Appraisal Tool. Random effects meta-analyses of proportions were performed where data, including subgroups, were amenable to quantitative synthesis. Heterogeneity was reported using tau2 and I2 statistics, and sensitivity analyses were also performed.

Results
Nineteen studies involving 13 045 nulliparous women were included but the heterogeneity of participant ages, parity and IUD types made quantitative synthesis of outcome data in totality inappropriate. The highest continuation rate obtained was 91.02% (95% CI 88.01% to 93.64%) for the smaller TCu 380A at 12 months post insertion.

Conclusions
Evidence for IUD use in young nulliparous women based on IUD type remains limited. Smaller sized IUD types appear better suited to this group of IUD users, however, more research is needed.

Protocol for a systematic review of interventions targeting mental health, cognition or psychological well-being among individuals with long COVID

Introduction
For some people, COVID-19 infection leads to negative health impacts that can last into the medium or long term. The long-term sequelae of COVID-19 infection, or ‘long COVID’, negatively affects not only physical health, but also mental health, cognition or psychological well-being. Complex, integrated interventions are recommended for long COVID, including psychological components; however, the effectiveness of such interventions has yet to be critically evaluated. This protocol describes a systematic review to be conducted of scientific literature reporting on clinical trials of interventions to promote mental health, cognition or psychological well-being among individuals with long COVID.

Methods and analysis
The Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines will be followed. A health sciences librarian will identify the relevant literature through comprehensive systematic searches of Medline, Embase, APA PsycINFO, Cumulative Index to Nursing and Allied Health Literature, medRxiv, PsyArXiv, China National Knowledge Internet and WANFANG Data databases, as well as The Cochrane Central Register of Controlled Trials, clinicaltrials.gov and the WHO International Clinical Trials Registry Platform. Studies will be selected through a title and abstract review, followed by a full-text review using inclusion and exclusion criteria. Data extracted will include intervention descriptions and efficacy metrics. Data will be narratively synthesised; if the data allow, a meta-analysis will be conducted. Risk of bias assessment will be conducted using the Cochrane Risk of Bias 2.0 tool.

Ethics and dissemination
Ethical approval for systematic reviews is not required. As researchers and clinicians respond to the new clinical entity that long COVID represents, this review will synthesise a rapidly emerging evidence base describing and testing interventions to promote mental health, cognition or psychological well-being. Results will therefore be disseminated through an open-access peer-reviewed publication and conference presentations to inform research and clinical practice.

Effects of telemedicine interventions on essential hypertension: a protocol for a systematic review and meta-analysis

Introduction
Essential hypertension is a major preventable risk factor for early cardiovascular disease, premature death and disability. It has been reported that telemedicine interventions can provide an innovative solution to essential hypertension to overcome the barriers that exist in traditional treatment or control. Nevertheless, this subject has not been thoroughly investigated. The goal of this study is to systematically evaluate and describe the impact of telemedicine interventions on essential hypertension.

Methods and analysis
To find relevant research, we will conduct a systematic literature search of three databases (PubMed, Embase and Cochrane Library), with no language limitations, in addition to researching grey literature. Two reviewers will extract the data individually, and any disagreements will be resolved by discussion or by a third reviewer. The randomised controlled trials will be chosen based on predetermined inclusion criteria. Primary outcomes will include systolic blood pressure and diastolic blood pressure after the telemedicine intervention. Secondary outcomes will include medication adherence (eg, the Morisky Medication Adherence Questionnaire), quality of life (eg, the MOS item scale of the Health Survey Short Form 36 questionnaire), blood pressure control rate and adverse events (eg, stroke, chronic renal failure, aortic dissection, myocardial infarction and heart failure). The quality of the included studies will be assessed using the Cochrane risk-of-bias method. The data will be analysed using RevMan V.5.3.5 software and STATA V.16.0 software. If heterogeneity testing reveals little or no statistical heterogeneity, a fixed effect model will be used for data synthesis; otherwise, a random effect model would be employed. We will synthesise the available evidence to perform a high-quality meta-analysis.

Ethics and dissemination
This project does not require ethical approval because it will be conducted using publicly available documents. The review’s findings will be published in peer-reviewed journals and publications.

Prevalence and risks of tuberculosis multimorbidity in low-income and middle-income countries: a meta-review

Objectives
Co-occurrence of tuberculosis (TB) with other chronic conditions (TB multimorbidity) increases complexity of management and adversely affects health outcomes. We aimed to map the prevalence of the co-occurrence of one or more chronic conditions in people with TB and associated health risks by systematically reviewing previously published systematic reviews.

Design
Systematic review of systematic reviews (meta-review).

Setting
Low-income and middle-income countries (LMICs).

Papers
We searched in Medline, Embase, PsycINFO, Social Sciences Citation Index, Science Citation Index, Emerging Sources Citation Index and Conference Proceedings Citation Index, and the WHO Global Index Medicus from inception to 23 October 2020, contacted authors and reviewed reference lists. Pairs of independent reviewers screened titles, abstracts and full texts, extracted data and assessed the included reviews’ quality (AMSTAR2). We included systematic reviews reporting data for people in LMICs with TB multimorbidity and synthesised them narratively. We excluded reviews focused on children or specific subgroups (eg, incarcerated people).

Primary and secondary outcome measures
Prevalence or risk of TB multimorbidity (primary); any measure of burden of disease (secondary).

Results
From the 7557 search results, 54 were included, representing >6 296 000 people with TB. We found that the most prevalent conditions in people with TB were depression (45.19%, 95% CI: 38.04% to 52.55%, 25 studies, 4903 participants, I2=96.28%, high quality), HIV (31.81%, 95% CI: 27.83% to 36.07%, 68 studies, 62 696 participants, I2=98%, high quality) and diabetes mellitus (17.7%, 95% CI: 15.1% to 20.0.5%, 48 studies, 48,036 participants, I2=98.3%, critically low quality).

Conclusions
We identified several chronic conditions that co-occur in a significant proportion of people with TB. Although limited by varying quality and gaps in the literature, this first meta-review of TB multimorbidity highlights the magnitude of additional ill health burden due to chronic conditions on people with TB.

Global evidence on falls and subsequent social isolation in older adults: a scoping review

Background
Falls are a leading cause of injury-related hospitalizations among adults aged 65 years and older and may result in social isolation.

Objective
To summarise evidence on falls and subsequent social isolation and/or loneliness in older adults through a scoping review.

Eligibility criteria
Studies were eligible for inclusion if the population had a mean age of 60 years or older, they examined falls and subsequent social isolation, loneliness, fear of falling or risk factors and were primary studies (eg, experimental, quasi-experimental, observational and qualitative).

Sources of evidence
MEDLINE, CINAHL, Embase, Ageline and grey literature from inception until 11 January 2021.

Charting methods
A screening and charting form was developed and pilot-tested. Subsequently, two reviewers screened citations and full-text articles, and charted the evidence.

Results
After screening 4993 citations and 304 full-text articles, 39 studies were included in this review. Participants had a history of falling (range: 11% to 100%). Most studies were conducted in Europe (44%) and North America (33%) and were of the cross-sectional study design (66.7%), in the community (79%). Studies utilised 15 different scales. Six studies examined risk factors for social isolation and activity restriction associated with fear of falling. Six studies reported mental health outcomes related to falls and subsequent social isolation.

Conclusions
Consistency in outcome measurement is recommended, as multiple outcomes were used across the included studies. Further research is warranted in this area, given the ageing population and the importance of falls and social isolation to the health of older adults.

Exercise training modalities in patients with lung cancer: a protocol for systematic review and network meta-analysis

Introduction
Lung cancer is a common malignancy and a major cause of cancer-related deaths worldwide, ranking high in terms of morbidity and prevalence. Exercise is a well-established recovery aid for many chronic respiratory conditions and lung cancer. However, it is difficult to determine the superiority of different exercise training modalities using randomised controlled trials (RCTs) or pairwise meta-analyses. Our Bayesian network meta-analysis (NMA) aimed to compare the impact of different perioperative exercise training modalities on lung function, exercise capacity, adverse events, health-related quality of life and mortality in patients undergoing lung cancer surgery, including preoperative and postoperative patients.

Methods and analysis
We will perform a comprehensive literature search using PubMed, EMBASE, Cochrane Library and Web of Science, from inception to May 2022, to identify studies that potentially provide data regarding exercise training modalities for patients with lung cancer. We will assess the risk of bias according to the Cochrane risk-of-bias tool and certainty of evidence for the main outcomes using the Grading of Recommendations Assessment, Development and Evaluation framework. Pairwise meta-analyses will be conducted using a random effects model and Stata software, and the NMA will be analysed using R software.

Ethics and dissemination
Ethical approval and patient consent were not required because this study was a meta-analysis of published RCTs. The results of this study are submitted to a peer-reviewed journal for publication.

Clinical prediction models for multidrug-resistant organism colonisation or infection in critically ill patients: a systematic review protocol

Introduction
Multidrug-resistant organisms (MDROs) are pathogenic bacteria that are the leading cause of hospital-acquired infection which is associated with high morbidity and mortality rates in intensive care units, increasing hospitalisation duration and cost. Predicting the risk of MDRO colonisation or infection for critically ill patients supports clinical decision-making. Several models predicting MDRO colonisation or infection have been developed; however, owing to different disease scenarios, bacterial species and few externally validated cohorts in different prediction models; the stability and applicability of these models for MDRO colonisation or infection in critically ill patients are controversial. In addition, there are currently no standardised risk scoring systems to predict MDRO colonisation or infection in critically ill patients. The aim of this systematic review is to summarise and assess models predicting MDRO colonisation or infection in critically ill patients and to compare their predictive performance.

Methods and analysis
We will perform a systematic search of PubMed, Cochrane Library, CINAHL, Embase, Web of science, China National Knowledge Infrastructure and Wanfang databases to identify all studies describing the development and/or external validation of models predicting MDRO colonisation or infection in critically ill patients. Two reviewers will independently extract and review the data using the Data Extraction for Systematic Reviews of Prediction Modelling Studies checklist; they will also assess the risk of bias using the Prediction Model Risk of Bias Assessment Tool. Quantitative data on model predictive performance will be synthesised in meta-analyses, as applicable.

Ethics and dissemination
Ethical permissions will not be required because all data will be extracted from published studies. We intend to publish our results in peer-reviewed scientific journals and to present them at international conferences on critical care.
