Introduction
Colonoscopy quality can vary depending on endoscopist-related factors. Quality indicators, such as adenoma detection rate (ADR), have been adopted to reduce variations in care. Several interventions aim to improve ADR, but these fall into several domains that have traditionally been difficult to compare. We will conduct a systematic review and network meta-analysis of randomised controlled trials evaluating the efficacies of interventions to improve colonoscopy quality and report our findings according to clinically relevant interventional domains.

Methods and analysis
We will search MEDLINE (Ovid), PubMed, EMBASE, CINAHL, Web of Science, Scopus and Evidence-Based Medicine from inception to September 2022. Four reviewers will screen for eligibility and abstract data in parallel, with two accordant entries establishing agreement and with any discrepancies resolved by consensus. The primary outcome will be ADR. Two authors will independently conduct risk of bias assessments. The analyses of the network will be conducted under a Bayesian random-effects model using Markov-chain Monte-Carlo simulation, with 10 000 burn-ins and 100 000 iterations. We will calculate the ORs and corresponding 95% credible intervals of network estimates with a consistency model. We will report the impact of specific interventions within each domain against standard colonoscopy. We will perform a Bayesian random-effects pairwise meta-analysis to assess heterogeneity based on the I2 statistic. We will assess the certainty of evidence using the Grading of Recommendations Assessment, Development and Evaluation framework for network meta-analyses.

Ethics and dissemination
Our study does not require research ethics approval given the lack of patient-specific data being collected. The results will be disseminated at national and international gastroenterology conferences and peer-reviewed journals.

PROSPERO registration number
CRD42021291814.

Only 13% of patients who met all 2013 USPSTF screening eligibility criteria were screened.

Introduction
Cervical cancer (CC) causes thousands of deaths each year. Nearly 100% of cases are caused by oncogenic strains of human papillomavirus (HPV). In most industrialised countries, CC screening (CCS) is based on the detection of HPV infections. For many reasons including lower adherence to CCS, underserved women are more likely to develop CC, and die from it. We aim to demonstrate that the use of incentives could improve screening rates among this population.

Methods and analysis
Our cluster randomised, controlled trial will include 10 000 women aged 30–65 years eligible for CCS, living in deprived areas in four French departments, two mainlands and two overseas, and who did not perform physician-based HPV testing within the framework of the nationally organised screening programme. HPV self-sampling kit (HPVss) will be mailed to them. Two interventions are combined in a factorial analysis design ending in four arms: the possibility to receive or not a financial incentive of 20 and to send back the self-sampling by mail or to give it to a health professional, family doctor, gynaecologist, midwife or pharmacist. The main outcome is the proportion of women returning the HPVss, or doing a physician-based HPV or pap-smear test the year after receiving the HPVss. 12-month follow-up data will be collected through the French National Health Insurance database. We expect to increase the return rate of HPV self-samples by at least 10% (from 20% to 30%) compared with the postal return without economic incentive.

Ethics and dissemination
Ethics approval was first obtained on 2 April 2020, then on July 29 2022. The ethics committee classified the study as interventional with low risk, thus no formal consent is required for inclusion. The use of health insurance data was approved by the Commission Nationale Informatique et Libertés on 14 September 2021 (ref No 920276). An independent data security and monitoring committee was established. The main trial results will be submitted for publication in a peer-reviewed journal.

Trial registration number
NCT04312178.

Objectives
This research aimed to develop a simple and effective acute coronary syndrome (ACS) screening model in order to intervene early and focus on prevention in patients presenting with arteriosclerosis.

Design
A case–control study.

Setting
The study used a cross-sectional survey to collect data from 2243 patients who completed anonymous electronic medical record (EMR) data and coronary angiography was gathered at a hospital in Shandong Province between December 2013 and April 2016.

Participants
Adults 18 years old and above diagnosed as ACS or non-ACS according to the records in hospital EMR database, and with completed basic information (age and sex).

Predictors
54 laboratory biomarkers and demographic factors (age and sex).

Statistical analysis
A dataset without missing data of all patients’ laboratory indicators and demographic factors was divided into training set and validation set after being balanced. After the training set balanced, area under the curve of random forest (AUCRF) and least absolute shrinkage and selection operator (LASSO) regression were used for feature extraction. Then two set random forest models were established with the different feature sets, and the process of comparison and analysis was made to evaluate models for the optimal model including sensitivity, accuracy and AUC receiver operating characteristic curves with the internal validation set.

Main outcome measures
To establish an ACS screening model.

Results
An RF model with 31 features selected by LASSO with an AUC of 0.616 (95% CI 0.650 to 0.772), a sensitivity of 0.832 and an accuracy of 0.714 in the validation set. The other RF model with 27 features selected by AUCRF with an AUC of 0.621 (95% CI 0.664 to 0.785), a sensitivity of 0.849 and an accuracy of 0.728 in the validation set.

Conclusions
The established ACS screening model with 27 clinical features provides a better performance for practical solution in predicting ACS.

Objective
To examine adolescent healthcare clinicians’ self-reported screening practices as well as their knowledge, attitudes, comfort level and challenges with screening and counselling adolescents and young adults (AYA) for cigarette, e-cigarette, alcohol, marijuana, hookah and blunt use.

Design
A 2016 cross-sectional survey.

Setting
Academic departments and community-based internal medicine, family medicine and paediatrics practices.

Participants
Adolescent healthcare clinicians (N=771) from 12 US medical schools and respondents to national surveys. Of the participants, 36% indicated male, 64% female, mean age was 44 years (SD=12.3); 12.3% of participants identified as Asian, 73.7% as white, 4.8% as black, 4.2% as Hispanic and 3.8% as other.

Primary and secondary outcome measures
Survey items queried clinicians about knowledge, attitudes, comfort level, self-efficacy and challenges with screening and counselling AYA patients about marijuana, blunts, cigarettes, e-cigarettes, hookah and alcohol.

Results
Participants were asked what percentage of their 10–17 years old patients they screened for substance use. The median number of physicians reported screening 100% of their patients for cigarette (1st, 3rd quartiles; 80, 100) and alcohol use (75, 100) and 99.5% for marijuana use (50,100); for e-cigarettes, participants reported screening half of their patients and 0.0% (0, 50), (0, 75)) reported screening for hookah and blunts, respectively. On average (median), clinicians estimated that 15.0% of all 10–17 years old patients smoked cigarettes, 10.0% used e-cigarettes, 20.0% used marijuana, 25.0% drank alcohol and 5.0% used hookah or blunts, respectively; yet they estimated lower than national rates of use of each product for their own patients. Clinicians reported greater comfort discussing cigarettes and alcohol with patients and less comfort discussing e-cigarettes, hookah, marijuana and blunts.

Conclusions
This study identified low rates of screening and counselling AYA patients for use of e-cigarettes, hookahs and blunts by adolescent healthcare clinicians and points to potential missed opportunities to improve prevention efforts.

Objective
To assess the practice of cervical cancer screening and its associated factors among women aged 30–49 years.

Design
Community-based cross-sectional survey.

Setting
Mertule Mariam Town, Northwest Ethiopia, 1 May–20 June 2021.

Participants
Women aged 30–49 years who were living in the study area were eligible for inclusion. A systematic random sampling technique was used to select study participants. A total of 488 respondents participated in the study. Data were collected by using interviewer-administered structured questionnaires. Data were entered into EpiData V.3.1 and then exported to SPSS V.25 for analysis. Bivariable and multivariable logistic regression analyses were done.

Outcome measures
Prevalence of cervical cancer screening and factors associated with screening utilisation.

Results
The prevalence of cervical cancer screening was found to be 14.1%. Age (≤16 years) at first sexual intercourse (adjusted OR 14.89, 95% CI 6.21 to 35.74), history of sexually transmitted disease (11.65, 4.56 to 29.78), having multiple sexual partners (11.65, 4.56 to 29.78), having good knowledge about cervical cancer screening (4.72, 2.33 to 9.56) and having a family history of cervical cancer (4.72, 2.33 to 9.56) were statistically significantly associated factors for utilisation of cervical cancer screening.

Conclusion
Utilisation of cervical cancer screening was low in Northwest Ethiopia. Educational status, age at first sexual intercourse, history of multiple sexual partners, sexually transmitted disease, family history of cervical cancer and knowledge about cervical cancer screening were significant factors for utilisation of cervical cancer screening.

Objectives
Some migrant groups are disproportionately affected by key infectious diseases in European countries. These pose a challenge for healthcare systems providing care to these groups. We aimed to explore the views of general practitioners (GPs) on the acceptability, adaptability and feasibility of a multidisease screening programme based on an innovative clinical decision-support system for migrants (the ISMiHealth tool), by examining the current gaps in healthcare provision and areas of good practice and the usefulness and limitations of training in the health needs of migrants.

Methods
We undertook a qualitative descriptive study and carried out a series of focus groups (FGs) taking a pragmatic utilitarian approach. Participants were GPs from the four primary healthcare (PHC) centres in Catalonia, Spain, that piloted an intervention of the ISMiHealth tool. GPs were recruited using purposive and convenience sampling. FG discussions were transcribed and analysed using thematic content analysis.

Results
A total of 29 GPs participated in four FGs. Key themes identified were: (1) GPs found the ISMiHealth tool to be very useful for helping to identify specific health problems in migrants, although there are several additional barriers to screening as part of PHC, (2) the importance of considering cultural perspectives when caring for migrants, and of the impact of migration on mental health, (3) the important role of PHC in healthcare provision for migrants and (4) key proposals to improve screening of migrant populations. GPs also highlighted the urgent need, to shift to a more holistic and adequately resourced approach to healthcare in PHC.

Conclusions
GPs supported a multidisease screening programme for migrant populations using the ISMiHealth tool, which aided clinical decision-making. However, intercultural participatory approaches will need to be adopted to address linguistic and cultural barriers to healthcare access that exist in migrant communities.
