Development of a risk prediction score for screening for HBV, HCV and HIV among migrants in France: results from a multicentre observational study (STRADA study).

OBJECTIVES: Migrants from high HIV, hepatitis B virus (HBV) or hepatitis C virus (HCV) endemicity regions have a great burden of these infections and related diseases in the host countries. This study aimed to assess the predictive capacity of the Test Rapide d'Orientation Diagnostique (TROD) Screen questionnaire for HIV, HBV and HCV infections among migrants arriving in France. DESIGN: An observational and multicentre study was conducted among migrants. A self-questionnaire on demographic characteristics, personal medical history and sexual behaviours was completed. SETTING: The study was conducted in the centres of the French Office for Immigration and Integration (OFII). PARTICIPANTS: Convenience sampling was used to select and recruit adult migrants between January 2017 and March 2020. OUTCOME MEASURES: Participants were tested for HIV, HBV and HCV with rapid tests. For each infection, the test performance was assessed using receiver operating characteristics curves, using area under the curve (AUC) as a measure of accuracy. RESULTS: Among 21 133 regular migrants seen in OFII centres, 15 343 were included in the study. The participants' mean age was 35.6 years (SD±11.1). The prevalence (95% CI) of HBV, HCV and HIV was 2.0% (1.8% to 2.2%), 0.3% (0.2% to 0.4%) and 0.3% (0.2% to 0.4%), respectively. Based on the sensitivity-specificity curve analysis, the cut-off points (95% CI) chosen for the risk score were: 2.5 (2.5 to 7.5) for HBV infection in men; 6.5 (0.5 to 6.5) for HBV infection in women; 9.5 (9.5 to 12.5) for HCV infection; and 10.5 (10.0 to 18.5) for HIV infection. Test performance was highest for HIV (AUC=82.15% (95% CI 74.54% to 87.99%)), followed by that for HBV in men (AUC=79.22%, (95% CI 76.18% to 82.26%)), for HBV in women (AUC=78.83 (95% CI 74.54% to 82.10%)) and that for HCV (AUC=75.95% (95% CI 68.58% to 83.32%)). CONCLUSION: The TROD screen questionnaire showed good overall performance for predicting HIV, HBV and HCV infections among migrants in OFII centres. It could be used to optimise screening for these infections and to propose rapid screening tests to those who are at high risk. TRIAL REGISTRATION NUMBER: NCT02959684.

Perceptions of height and weight screening and associations with body image: a cross-sectional study in early primary school children.

BACKGROUND: Despite parental concern, few studies have investigated children's experiences with school-based screening of growth deviations. This study aimed to explore perceptions of height and weight screening and associations with body size dissatisfaction (BSD) among third-grade children aged 8-9 years in central Norway. METHODS: In a cross-sectional study between November 2021 and April 2022, perceptions of height and weight screening and BSD were assessed individually among 209 children (49% girls) through researcher-assisted interviews. RESULTS: Most children indicated satisfaction with the screening by selecting a happy emoji, whereas only 1% indicated dissatisfaction, by selecting an unhappy emoji. However, 23%-30% selected a neutral emoji, indicating either neutrality or a response between satisfaction and dissatisfaction. No difference in the perception of height and weight screening was found between genders or body mass index (BMI). Children with parents from non-Western countries had a higher risk of being less satisfied with the height screening (OR=3.0, 95% CI 1.2 to 7.3) than those from Western origin, and children attending schools with lower socioeconomic status (SES) had increased risk of being less satisfied with both height (OR=5.5, 95% CI 2.2 to 13.5) and weight screening (OR=4.0, 95% CI 1.7 to 9.3), compared with children from schools with medium-high SES. Twenty-three percent reported BSD, in which 14% and 9% desired a thinner or larger body, respectively, independent of gender and BMI. No association was found between BSD and the perception of weighing (OR=1.1, 95% CI 0.6 to 2.4), however, BSD was associated with being more satisfied with height screening (OR=0.3, 95% CI 0.1 to 0.8). CONCLUSION: In the present sample, most children indicated satisfaction with school-based height and weight screening, with no differences between gender or BMI category. However, more children of non-Western origin and from areas with low SES reported less satisfaction with the screening, independent of BSD.

Simultaneous alleviation of verification and reference standard biases in a community-based tuberculosis screening study using Bayesian latent class analysis.

BACKGROUND: Estimation of prevalence and diagnostic test accuracy in tuberculosis (TB) prevalence surveys suffer from reference standard and verification biases. The former is attributed to the imperfect reference test used to bacteriologically confirm TB disease. The latter occurs when only the participants screening positive for any TB-compatible symptom or chest X-ray abnormality are selected for bacteriological testing (verification). Bayesian latent class analysis (LCA) alleviates the reference standard bias but suffers verification bias in TB prevalence surveys. This work aims to identify best-practice approaches to simultaneously alleviate the reference standard and verification biases in the estimates of pulmonary TB prevalence and diagnostic test performance in TB prevalence surveys. METHODS: We performed a secondary analysis of 9869 participants aged ≥15 years from a community-based multimorbidity screening study in a rural district of KwaZulu-Natal, South Africa (Vukuzazi study). Participants were eligible for bacteriological testing using Xpert Ultra and culture if they reported any cardinal TB symptom or had an abnormal chest X-ray finding. We conducted Bayesian LCA in five ways to handle the unverified individuals: (i) complete-case analysis, (ii) analysis assuming the unverified individuals would be negative if bacteriologically tested, (iii) analysis of multiply-imputed datasets with imputation of the missing bacteriological test results for the unverified individuals using multivariate imputation via chained equations (MICE), and simultaneous imputation of the missing bacteriological test results in the analysis model assuming the missing bacteriological test results were (iv) missing at random (MAR), and (v) missing not at random (MNAR). We compared the results of (i)-(iii) to the analysis based on a composite reference standard (CRS) of Xpert Ultra and culture. Through simulation with an overall true prevalence of 2.0%, we evaluated the ability of the models to alleviate both biases simultaneously. RESULTS: Based on simulation, Bayesian LCA with simultaneous imputation of the missing bacteriological test results under the assumption that the missing data are MAR and MNAR alleviate the reference standard and verification biases. CRS-based analysis and Bayesian LCA assuming the unverified are negative for TB alleviate the biases only when the true overall prevalence is <3.0%. Complete-case analysis produced biased estimates. In the Vukuzazi study, Bayesian LCA with simultaneous imputation of the missing bacteriological test results under the MAR and MNAR assumptions produced overall PTB prevalence of 0.9% (95% Credible Interval (CrI): 0.6-1.9) and 0.7% (95% CrI: 0.5-1.1) respectively alongside realistic estimates of overall diagnostic test sensitivity and specificity with substantially overlapping 95% CrI. The CRS-based analysis and Bayesian LCA assuming the unverified were negative for TB produced 0.7% (95% CrI: 0.5-0.9) and 0.7% (95% CrI: 0.5-1.2) overall PTB prevalence respectively with realistic estimates of overall diagnostic test sensitivity and specificity. Unlike CRS-based analysis, Bayesian LCA of multiply-imputed data using MICE mitigates both biases. CONCLUSION: The findings demonstrate the efficacy of these advanced techniques in alleviating the reference standard and verification biases, enhancing the robustness of community-based screening programs. Imputing missing values as negative for bacteriological tests is plausible under realistic assumptions.

Nicotine Screening and Cessation Education Among Patients Awaiting Total Joint Arthroplasty: A Quality Improvement Project.

Orthopedic surgical patients who use nicotine are at a high risk for postoperative complications including infection, respiratory failure, cardiac arrest, and death. Periprosthetic joint infections may result from nicotine-induced immunosuppression and microvascular changes, increasing perioperative morbidity and mortality. These complications result in higher health care costs, increased length of stay, and loss of reimbursement due to readmissions. Four weeks of nicotine cessation prior to arthroplasty decreases these risks; however, perioperative teams may lack reliable nicotine screening and cessation education methods. This project identified inconsistencies in nicotine screening and cessation counseling in the preoperative setting, which contributed to surgery cancellations among patients who required to demonstrate nicotine cessation preoperatively. Standardization of preoperative nicotine screening and patient cessation education resources can improve the identification of orthopedic patients who use nicotine and provide concrete, proven methods of achieving nicotine cessation prior to elective primary arthroplasty. Investment from perioperative staff is essential to ensure success.

Nonproliferative diabetic retinopathy dataset(NDRD): A database for diabetic retinopathy screening research and deep learning evaluation.

OBJECTIVES: In this article, we provide a database of nonproliferative diabetes retinopathy, which focuses on early diabetes retinopathy with hard exudation, and further explore its clinical application in disease recognition. METHODS: We collect the photos of nonproliferative diabetes retinopathy taken by Optos Panoramic 200 laser scanning ophthalmoscope, filter out the pictures with poor quality, and label the hard exudative lesions in the images under the guidance of professional medical personnel. To validate the effectiveness of the datasets, five deep learning models are used to perform learning predictions on the datasets. Furthermore, we evaluate the performance of the model using evaluation metrics. RESULTS: Nonproliferative diabetes retinopathy is smaller than proliferative retinopathy and more difficult to identify. The existing segmentation models have poor lesion segmentation performance, while the intersection over union (IOU) value for deep lesion segmentation of models targeting small lesions can reach 66.12%, which is higher than ordinary lesion segmentation models, but there is still a lot of room for improvement. CONCLUSION: The segmentation of small hard exudative lesions is more challenging than that of large hard exudative lesions. More targeted datasets are needed for model training. Compared with the previous diabetes retina datasets, the NDRD dataset pays more attention to micro lesions.

Non-invasive hemoglobin screening device: a promising digital method for reducing anemia prevalence through routine screening and timely intervention.

BACKGROUND: Several non-invasive technologies are nowadays available in the market which claim to determine the hemoglobin levels instantly without the requirement of the blood sample. But no study has shown the significance of such non-invasive devices on a routine basis for determining their impact on anemia reduction programs. This study is conducted to determine the impact of regular hemoglobin screening on the women population to determine its potential in reducing anemia, using a digitalized non-invasive device. METHOD: A cross-sectional study was conducted on 203 women of reproductive age group, residing in the Moradabad district. Repetitive readings were taken after a time interval of a minimum of 1 month for determining the impact of regular screening. The entire data collection process was carried out using the EzeCheck mobile app. RESULTS: It was observed that the prevalence of anemia was reduced upon the second time screening and was accepted by the women population. Repetitive testing has a significant impact on reducing anemia prevalence. Also, the simplified non-invasive technology for estimating the hemoglobin values, makes the user more comfortable to take the test. CONCLUSION: Non-invasive devices should be used regularly to keep track of hemoglobin levels which will help in the effective treatment of anemia. The mobile app-based testing could help to easily evaluate the reports of the patients from any remote location with instant result interpretation and health assistance.

The optimal cut-off score of the Eating Attitude Test-26 for screening eating disorders in Japan.

PURPOSE: The Eating Attitude Test-26 (EAT-26) is a screening tool for eating disorders (EDs) in clinical and non-clinical samples. The cut-off score was suggested to be varied according to target population. However, no studies have examined the appropriateness of the originally proposed score of 20 for screening DSM-5 eating disorders in Japan. This study aimed to identify an appropriate cut-off score to better differentiate clinical and non-clinical samples in Japan for EDs. METHODS: The participants consisted of 54 patients with anorexia nervosa restricting type, 58 patients with anorexia nervosa binge-eating/purging type, 37 patients with bulimia nervosa diagnosed according to DSM-5 criteria, and 190 healthy controls (HCs). Welch's t test was used to assess differences in age, body mass index (BMI), and total EAT-26 scores between HCs and patients with EDs. Receiver operating characteristic (ROC) analysis was conducted to identify the optimal cut-off score. RESULTS: The HCs had significantly higher BMI and lower total EAT-26 mean scores than patients with EDs. The area under the ROC curve was 0.925, indicating that EAT-26 had excellent performance in discriminating patients with EDs from HCs. An optimal cut-off score of 17 was identified, with sensitivity and specificity values of 0.866 and 0.868, respectively. CONCLUSIONS: The result supports the suggestions that optimal cut-off score should be different according to target populations. The newly identified cut-off score of 17 would enable the identification of patients with EDs who have been previously classified as non-clinical samples in the EAT-26 test. LEVEL OF EVIDENCE: III: evidence obtained from case-control analytic study.

Diabetes and Dyslipidemia Screening in Pediatric Practice.

The incidence of diabetes and hyperlipidemia are increasing at rapid rates in children. These conditions are associated with increased risk of macrovascular and microvascular complications causing major morbidity and mortality later in life. Early diagnosis and treatment can reduce the lifelong risk of complications from these diseases, exemplifying the importance of screening in the pediatric population. The following article presents a summary of the current guidelines for diabetes and hyperlipidemia screening in pediatric patients.

Point-of-care AI-enhanced novice echocardiography for screening heart failure (PANES-HF).

The increasing prevalence of heart failure (HF) in ageing populations drives demand for echocardiography (echo). There is a worldwide shortage of trained sonographers and long waiting times for expert echo. We hypothesised that artificial intelligence (AI)-enhanced point-of-care echo can enable HF screening by novices. The primary endpoint was the accuracy of AI-enhanced novice pathway in detecting reduced LV ejection fraction (LVEF) < 50%. Symptomatic patients with suspected HF (N = 100, mean age 61 ± 15 years, 56% men) were prospectively recruited. Novices with no prior echo experience underwent 2-weeks' training to acquire echo images with AI guidance using the EchoNous Kosmos handheld echo, with AI-automated reporting by Us2.ai (AI-enhanced novice pathway). All patients also had standard echo by trained sonographers interpreted by cardiologists (reference standard). LVEF < 50% by reference standard was present in 27 patients. AI-enhanced novice pathway yielded interpretable results in 96 patients and took a mean of 12 min 51 s per study. The area under the curve (AUC) of the AI novice pathway was 0.880 (95% CI 0.802, 0.958). The sensitivity, specificity, positive predictive and negative predictive values of the AI-enhanced novice pathway in detecting LVEF < 50% were 84.6%, 91.4%, 78.5% and 94.1% respectively. The median absolute deviation of the AI-novice pathway LVEF from the reference standard LVEF was 6.03%. AI-enhanced novice pathway holds potential to task shift echo beyond tertiary centres and improve the HF diagnostic workflow.

The identification and treatment of alcohol problems in primary care (iTAPP) study: protocol for a stepped wedge cluster randomized control trial testing the 15-method in a primary care setting.

BACKGROUND: The 15-method is a targeted screening and treatment approach for alcohol problems in primary care. The 15-method used in primary care has proven as effective as specialized treatment for mild to moderate alcohol dependence in Sweden. A feasibility study of the 15-method in Danish primary care found the method acceptable and feasible. AIMS: To evaluate the effectiveness of the 15-method in a Danish primary care setting in (1) lowering the proportion of patients exceeding the Danish low-risk alcohol consumption limit of ten standard units per week and a maximum of four standard units on a single day for men and women, and (2) increasing the likelihood of alcohol use being addressed during a consultation in general practice. Further, the rate of prescribed pharmacological treatment for alcohol problems (Disulfiram, Naltrexone, Acamprosate, and Nalmefene) will be measured along with the use of the biomarkers Alanine Transaminase and Gamma-Glutamyl Transferase. METHODS: Stepped wedge cluster randomized controlled trial in sixteen general practices in the Region of Southern Denmark. Following a three-month baseline, the practices are randomly assigned to launch dates in one of four clusters. General practitioners and nurses receive three hours of training in the 15-method before launch. Patient questionnaires will collect data on alcohol consumption levels among patients affiliated with the practices. The healthcare professionals will register consultations in which alcohol is addressed in their patient filing system. Pharmacological treatment rates and the use of biomarkers will be collected through Danish national registries. The study follows the Medical Research Council's guidelines for developing and evaluating complex interventions. DISCUSSION: From the patient's perspective, the 15-method may help identify alcohol-related problems at an earlier stage with flexible treatment offers in a familiar setting. For healthcare professionals, it addresses a traditionally challenging topic by equipping them with concrete tools, communication training, and clear treatment directives. From a societal perspective, primary care holds a unique position to identify hazardous and harmful alcohol use across different age groups, with potential public health and economic benefits through early identification and intervention. TRIAL REGISTRATION: Clinicaltrials.gov NCT05916027. Retrospectively registered 22 June 2023.

Screening for elder mistreatment in a Swiss emergency department: a prospective cohort study.

AIM OF THE STUDY: The mistreatment of older adults is a global and complex problem with varying prevalence. As there are no data on the prevalence of elder mistreatment in European emergency department populations, we aimed to translate and culturally adapt the Emergency Department Senior Abuse Identification (ED Senior AID) tool for German use, assess the positive screen rate for elder mistreatment with the German version, and compare characteristics of patients who screened positive and negative. METHODS: To assess the prevalence of elder mistreatment, we created a German version of the ED Senior AID tool. This tool identifies intentional or negligent actions by a caregiver or trusted person that cause harm or risk to an older adult. Then, the German ED Senior AID tool was applied to all consecutively presenting patients aged ≥65 years at our academic emergency department in the Northwest of Switzerland from 25 April to 30 May 2022. Usability was defined as the percentage of patients with completed assessments using the German ED Senior AID tool. RESULTS: We included 1010 patients aged ≥65 years, of whom 29 (2.9%) screened positive with the ED Senior AID tool. The patients who screened positive were older, more severely cognitively impaired, hospitalised more frequently, and presented with higher frailty scores than those who screened negative. Mortality up to 100 days after presentation was comparable in all patients (p = 0.861), regardless of their screening result. The tool showed good usability, with 73% of assessments completed. CONCLUSION: This is the first prospective investigation on the prevalence of elder mistreatment in a European emergency department setting. Overall, 2.9% of patients screened positive using a validated screening tool translated into German. TRIAL REGISTRATION: This study was registered with the National Institute of Health on ClinicalTrials.gov with the registration number NCT05400707.

Little associations exist between the three commonly used functional screening tests in collegiate athletes.

Although an abundant number of studies have investigated the predictability of the commonly used functional screening tests and despite their popularity and applicability, the relationships between these tests have rarely been studied and have not been well established. This study aimed to examine the potential association between the Functional Movement Screen (FMS), Y Balance Test (YBT), and Landing Error Scoring System (LESS). Six hundred twenty-seven Iranian collegiate athletes (347 males, age = 22.63 ± 4.07, weight = 75.98 ± 13.79, height = 181.99 ± 10.15, BMI = 22.84 ± 3.16; and 280 females, age = 22.22 ± 3.37, weight = 60.63 ± 9.58, height = 166.55 ± 6.49, BMI = 21.81 ± 2.84) participated in this study. Following a 5-min warm-up, each participant underwent a standardized screening battery including the FMS, YBT, and LESS, and the scores were recorded and live coded for the statistical analysis, except for the LESS. The LESS tests were video recorded and scored by one expert examiner using an open-source 2D video analysis software (Kinovea- version 0.9.5), afterwards. The Spearman correlation was utilized as a measure for the correlation, and the Mann‒Whitney U test with a significance level of 0.05 was used to check the differences between male and female athletes. The statistical analysis was performed with RStudio 2023.03.0 using R 4.3.1. A small correlation (0.364) was observed between the FMS composite score and the YBT in male athletes. All other pairwise correlations were negligible among male and female athletes, ranging from - 0.096 to 0.294. Reducing the FMS to the component scores targeting the lower extremities did not alter the correlation to the other screening scores. The median FMS composite score in female athletes was significantly higher than that in males (p < 0.001). Negligible correlations exist between the FMS, LESS, and YBT; they do not measure the same values and therefore are irreplaceable with one another. A combination of these tests as a standardized screening battery may potentially better identify injury-predisposed athletes than the application of each test as a stand-alone screening test. Females outperformed males in the FMS test significantly, so sex must be considered a key variable in the FMS studies. Males had slightly higher LESS scores (median difference = 0.5) than females, but this difference is not clinically meaningful. Future research should continue to explore the relationships between various functional screening tests and identify the most effective combinations for comprehensive assessment in different populations and sports disciplines.

The impact of living conditions and health interventions on tuberculosis, Denmark, 1876 to 2022.

BackgroundDenmark possesses an exceptional historical data collection on tuberculosis (TB) from 1876 to the present, providing a unique opportunity to assess TB epidemiology over 147 years in Denmark.AimOur aim was to describe the TB disease burden in Denmark in relation to historical events, living conditions and health interventions during the past 147 years.MethodsWe performed a nationwide register-based ecological study including all persons with TB in Denmark from 1876 through 2022, correlating the TB incidence to social, economic and health indicators.ResultsIn Denmark, the overall TB incidence and mortality declined markedly over the past 147 years, only marginally influenced by specific TB interventions such as sanatoria, Bacillus Calmette-Guèrin (BCG) vaccination, mass screenings and antibiotics. Parallel to this decline, the country experienced improved living conditions, as illustrated by decreased infant mortality and increased life expectancy and wealth. In 1978, Denmark became a low-incidence country for TB with risk groups predominantly affected, and with a continuous change in demographics towards fewer Danish-born cases and relatively more migrant cases.ConclusionsThe decline over time in TB incidence and mortality in Denmark preceded specific TB interventions and can, first of all, be attributed to improved living conditions. TB has now become a rare disease in Denmark, predominantly occurring in particular risk groups. Future elimination of TB will require a combination of specific health interventions in these risk groups combined with a continued focus on improving socioeconomic status and living conditions.

Hepatitis E virus infections in German blood donors: results of 8 years of screening, 2015 to 2022.

BackgroundAwareness of transfusion-transmitted hepatitis E raised in recent years led to the mandatory testing of blood donations in some European countries for hepatitis E virus (HEV) RNA. However, little is known about the epidemiology of HEV infections.AimTo and describe and analyse the epidemiology of HEV infections in blood donors in Germany.MethodsData from routine testing of therapeutic blood products donated between January 2015 and December 2022 at the Uni.Blutspendedienst OWL were analysed at the Institute of Laboratory and Transfusion Medicine, Heart and Diabetes Centre North Rhine-Westphalia. A total of 731,630 allogenic blood donations from 119,610 individual blood donors were tested for HEV RNA in minipools of 96 samples. The HEV RNA-positive donations were analysed for the presence of anti-HEV IgM and IgG. The HEV strains were genotyped and various clinical liver-specific parameters were determined.ResultsA total of 497 HEV-positive blood donations were identified, resulting in a yearly incidence of 1:1,474, from which 78.4% of the donations were RNA-only positive. Increased alanine aminotransferase activity was determined in 26.6% of HEV RNA-positive donors and was associated with the detection of IgG antibodies (1.2% anti-HEV IgM-positive, 11.9% anti-HEV IgM- and IgG-positive and 8.5% anti-HEV IgG-positive). An average incidence of 0.084-0.083% HEV RNA-positive donations in June and July in all years was observed, and a higher proportion of HEV RNA-positive men compared with women. All isolated HEV sequences corresponded to genotype 3.ConclusionOur results underline the necessity of HEV RNA screening in blood donations.

Identifying the blue patient: preoperative screening for depression.

Preoperative depression is an underappreciated comorbidity that has important implications for postoperative outcomes. Screening for symptoms of depression before surgery can identify patients with or without a previous diagnosis of depression who could benefit from perioperative interventions to improve mood. Preoperative screening programmes are feasible to implement, although care must be taken to ensure that patients who are most likely to benefit are included.

Interdisciplinary Role of Orthodontist in Screening and Managing Obstructive Sleep Apnea in Children and Adults.

Obstructive sleep apnea (OSA) can affect children and adults, and, if left untreated, could have a major impact on the general and overall well-being of the patient. Dental health care providers and orthodontists have an interdisciplinary role in screening patients at risk for OSA and make a referral to establish a definitive diagnosis by a sleep physician. The gold standard of diagnostic testing is polysomnography. The adeno-tonsillar hypertrophy is the primary cause of sleep apnea in children; therefore, adeno-tonsillectomy must be the first line of treatment. Post adeno-tonsillectomy, if there is residual OSA due to underlying skeletal discrepancy, the patient may be referred to an orthodontist for appropriate management. Currently the evidence in the literature for prophylactic growth modification in children to prevent OSA is weak. In adults, the gold standard for managing OSA is Positive Airway Pressure (PAP) therapy; however, adherence to this treatment is rather low. The oral appliance (OA) therapy is an alternate for PAP intolerant patients and for mild to moderate OSA patients. The OA therapy has to be administered by a qualified dentist or orthodontist after careful examination of dental and periodontal health as well as any pre-existing joint conditions. The OA therapy could cause OA-associated malocclusion and patients have to be made aware of prior to initiating treatment. In patients with severe OSA, surgical maxilla-mandibular advancement (MMA) is highly effective.

Internal validation of Automated Visual Evaluation (AVE) on smartphone images for cervical cancer screening in a prospective study in Zambia.

OBJECTIVES: Visual inspection with acetic acid (VIA) is a low-cost approach for cervical cancer screening used in most low- and middle-income countries (LMICs) but, similar to other visual tests, is subjective and requires sustained training and quality assurance. We developed, trained, and validated an artificial-intelligence-based "Automated Visual Evaluation" (AVE) tool that can be adapted to run on smartphones to assess smartphone-captured images of the cervix and identify precancerous lesions, helping augment VIA performance. DESIGN: Prospective study. SETTING: Eight public health facilities in Zambia. PARTICIPANTS: A total of 8204 women aged 25-55. INTERVENTIONS: Cervical images captured on commonly used low-cost smartphone models were matched with key clinical information including human immunodeficiency virus (HIV) and human papillomavirus (HPV) status, plus histopathology analysis (where applicable), to develop and train an AVE algorithm and evaluate its performance for use as a primary screen and triage test for women who are HPV positive. MAIN OUTCOME MEASURES: Area under the receiver operating curve (AUC); sensitivity; specificity. RESULTS: As a general population screening tool for cervical precancerous lesions, AVE identified cases of cervical precancerous and cancerous (CIN2+) lesions with high performance (AUC = 0.91, 95% confidence interval [CI] = 0.89-0.93), which translates to a sensitivity of 85% (95% CI = 81%-90%) and specificity of 86% (95% CI = 84%-88%) based on maximizing the Youden's index. This represents a considerable improvement over naked eye VIA, which as per a meta-analysis by the World Health Organization (WHO) has a sensitivity of 66% and specificity of 87%. For women living with HIV, the AUC of AVE was 0.91 (95% CI = 0.88-0.93), and among those testing positive for high-risk HPV types, the AUC was 0.87 (95% CI = 0.83-0.91). CONCLUSIONS: These results demonstrate the feasibility of utilizing AVE on images captured using a commonly available smartphone by nurses in a screening program, and support our ongoing efforts for moving to more broadly evaluate AVE for its clinical sensitivity, specificity, feasibility, and acceptability across a wider range of settings. Limitations of this study include potential inflation of performance estimates due to verification bias (as biopsies were only obtained from participants with visible aceto-white cervical lesions) and due to this being an internal validation (the test data, while independent from that used to develop the algorithm was drawn from the same study).
