Reinforcement learning for individualized lung cancer screening schedules: A nested case-control study.

BACKGROUND: The current guidelines for managing screen-detected pulmonary nodules offer rule-based recommendations for immediate diagnostic work-up or follow-up at intervals of 3, 6, or 12 months. Customized visit plans are lacking. PURPOSE: To develop individualized screening schedules using reinforcement learning (RL) and evaluate the effectiveness of RL-based policy models. METHODS: Using a nested case-control design, we retrospectively identified 308 patients with cancer who had positive screening results in at least two screening rounds in the National Lung Screening Trial. We established a control group that included cancer-free patients with nodules, matched (1:1) according to the year of cancer diagnosis. By generating 10,164 sequence decision episodes, we trained RL-based policy models, incorporating nodule diameter alone, combined with nodule appearance (attenuation and margin) and/or patient information (age, sex, smoking status, pack-years, and family history). We calculated rates of misdiagnosis, missed diagnosis, and delayed diagnosis, and compared the performance of RL-based policy models with rule-based follow-up protocols (National Comprehensive Cancer Network guideline; China Guideline for the Screening and Early Detection of Lung Cancer). RESULTS: We identified significant interactions between certain variables (e.g., nodule shape and patient smoking pack-years, beyond those considered in guideline protocols) and the selection of follow-up testing intervals, thereby impacting the quality of the decision sequence. In validation, one RL-based policy model achieved rates of 12.3% for misdiagnosis, 9.7% for missed diagnosis, and 11.7% for delayed diagnosis. Compared with the two rule-based protocols, the three best-performing RL-based policy models consistently demonstrated optimal performance for specific patient subgroups based on disease characteristics (benign or malignant), nodule phenotypes (size, shape, and attenuation), and individual attributes. CONCLUSIONS: This study highlights the potential of using an RL-based approach that is both clinically interpretable and performance-robust to develop personalized lung cancer screening schedules. Our findings present opportunities for enhancing the current cancer screening system.

Oral Cancer Risk and Screening Prevalence Among Hospitalized Women.

Background Oral cancer screenings are often on the back burner in the face of other cancer screenings. In high-risk individuals, early detection of oral cancer has a better prognosis and survival. Hospitalization may offer an opportunity to target high-risk populations. This study evaluates the prevalence of women at high risk for oral cancer among hospitalized women and their preference for oral cancer screening. Design and participants Five hundred and ten cancer-free women admitted to the hospital under the internal medicine service at an academic center were enrolled to participate in the study. Three hundred and seventy women were at high risk for developing oral cancer, defined by smoking status, alcohol use, or both. High-risk women received bedside smoking cessation counseling and oral cancer informational handouts and were offered oral screening examinations during hospitalization. Six months after discharge, study participants received a follow-up phone call to determine if these women discussed oral cancer screening with their primary care physicians at the follow-up visit. Results Seventy-three percent of the hospitalized women were at high risk for developing oral cancer. Fifty-seven percent of high-risk women reported having no primary dentist. High-risk women were more likely to be younger, reported a disability, and had a lower comorbidity burden than the average-risk group. Only 41% of high-risk hospitalized women received oral cancer screening examinations during the hospital stay. Post-hospitalization, 66% of high-risk patients discussed oral cancer screening with their primary care. Conclusion Almost three-fourths of hospitalized women are at high risk for developing oral cancer. Hospitalization provides an opportunity to educate and screen high-risk populations.

Routine Clinical Breast Examination Is a Low-Yield Practice Among Women at High Risk of Breast Cancer.

BACKGROUND: For women at increased risk of breast cancer, the National Comprehensive Cancer Network (NCCN) guidelines recommend clinical encounters every 6-12 months. While screening mammography has corresponded with a relative risk reduction in breast cancer mortality of approximately 20%, evidence validating clinical breast examination (CBE) as an efficacious screening modality is deficient. Our study aimed to assess the conventional merit of regular CBE for breast cancer detection among individuals at increased risk of breast cancer development. METHODS: Women > 18 years with documented high-risk encounters at Corewell Health West from 1 January 2018 to 31 December 22 were retrospectively reviewed. High-risk criteria included genetic predisposition, 5-year (> 1.7%) or lifetime (> 20%) Tyrer-Cuzick and/or Gail Model risk estimations, thoracic radiotherapy before age 30 years, lobular carcinoma in-situ, or atypical hyperplasia. Patients with a history of breast cancer or bilateral prophylactic mastectomy prior to 2018 were excluded. RESULTS: Of the 9171 cumulative high-risk encounters among 2493 women, only one breast cancer was detected by CBE. CBE resulted in 1 (0.04%) cancer diagnosis compared with 30 (1.2%) detected on screening imaging and 10 (0.4%) self-reported. Of the 30 image-detected cancers, 28 (93.3%) had no detectable clinical findings at the time of preoperative consultation. Self-reported and CBE-detected cancers were more likely to be of higher clinical stage compared with imaging-detected malignancies. CONCLUSIONS: The role of routine CBE as a cancer detection modality in the high-risk patient population appears to be limited. Telemedicine can be offered to individuals who have completed screening imaging but are unable to commit and/or are inconvenienced by in-person high-risk breast cancer assessments.

Gastric Cancer: Clinical Features, Screening, Diagnosis, Treatment, and Prevention.

The objective of this article is to highlight the clinical features, screening, diagnosis, treatment, and prevention of gastric cancer (GC). Early GC is often asymptomatic leading to frequent delays in diagnosis. Weight loss and persistent abdominal pain are the most common symptoms at initial diagnosis. The diagnosis of GC typically involves a combination of endoscopy, biopsy, and imaging studies. Endoscopic resection techniques are emerging as successful treatment options for early GC. Treatment options for advanced GC include surgery and chemotherapy. The first line chemotherapy for advanced GC consists of doublet therapy with a combination of platinum and fluoropyrimidines. Trastuzumab, a monoclonal antibody, is used in the treatment of human epidermal growth factor 2 positive GCs. Antiangiogenic agents and immunotherapy are also useful in the treatment of GC. Currently there are no GC screening guidelines in the United States, but they exist in other regions where there is increased prevalence of GC. Prevention strategies for GC include Helicobacter pylori eradication and adoption of a healthy diet consisting of fruits and vegetables.

PSA Stratification for Predicting Advanced Prostate Cancer Events in Men Approaching Age-Limits for Recommended Screening.

PURPOSE: To quantify the ability of various PSA values in predicting the likelihood of developing metastatic or fatal prostate cancer in older men. MATERIALS/METHODS: We used a random sample of patients in the United States Veterans Health Administration to identify 80,706 men who had received PSA testing between ages 70 to 75. Our primary endpoint was time to development of either metastatic prostate cancer or death from prostate cancer. We used cumulative/dynamic modeling to account for competing events (death from non-prostate cancer causes) in studying both the discriminative ability of PSA as well as for positive predictive value and negative predictive value at three time points. RESULTS: PSA demonstrated time-dependent predictive discrimination, with receiver operating characteristic area under the curve at 5, 10, and 14 years decreasing from 0.83 to 0.77 to 0.73, respectively, but without statistically significant difference when stratified by race. At PSA thresholds between 1 and 8 ng/mL, the positive predictive value of developing advanced prostate cancer was significantly greater in Black than White patients. For instance, at a PSA > 3, at 5, 10, and 14 years, White patients had 2.4%, 2.9%, and 3.7% risk of an event, whereas Black patients had 4.3%, 6.5%, and 8.3% risk. CONCLUSIONS: In men aged 70 to 75 deciding whether to cease PSA testing with borderline-elevated PSA values, the risk of developing metastatic or fatal prostate cancer is quantifiable and relatively low. Risk assessment in this setting must account for the higher incidence of prostate cancer in Black men.

Relative timing of mammography and MRI for breast cancer screening: Impact on performance evaluation.

OBJECTIVE: Mammography and MRI screening typically occur in combination or in alternating sequence. We compared multimodality screening performance accounting for the relative timing of mammography and MRI and overlapping follow-up periods. METHODS: We identified 8,260 screening mammograms performed 2005-2017 in the Breast Cancer Surveillance Consortium, paired with screening MRIs within +/- 90 days (combined screening) or 91-270 days (alternating screening). Performance for combined screening [cancer detection rate (CDR) per 1000 examinations and sensitivity] was calculated with one-year follow-up for each modality, and with a single follow-up period treating the two tests as a single test. Alternating screening performance was calculated with one-year follow-up for each modality and also with follow-up ending at the next screen if within one year (truncated follow-up). RESULTS: For 3,810 combined screening pairs, CDR per 1000 screens was 6.8 (95%CI: 4.6-10.0) for mammography and 12.3 (95%CI: 9.3-16.4) for MRI as separate tests compared to 13.1 (95%CI: 10.0-17.3) as a single combined test. Sensitivity of each test was 48.1% (35.0%-61.5%) for mammography and 79.7% (95%CI: 67.7-88.0%) for MRI compared to 96.2% (95%CI: 85.9-99.0%) for combined screening. For 4,450 alternating screening pairs, mammography CDR per 1000 screens changed from 3.6 (95%CI: 2.2-5.9) to zero with truncated follow-up; sensitivity was incalculable (denominator=0). MRI CDR per 1000 screens changed from 12.1 (95%CI 9.3-15.8) to 11.7 (95%CI: 8.9-15.3) with truncated follow-up; sensitivity changed from 75.0% (95%CI 63.8-83.6%) to 86.7% (95%CI 75.5-93.2%). DISCUSSION: Updating auditing approaches to account for combined and alternating screening sequencing and to address outcome attribution issues arising from overlapping follow-up periods can improve the accuracy of multimodality screening performance evaluation.

Attitude to cervical cancer screening and human papillomavirus testing experience in self-sampled Nigerian women.

Background: Cervical cancer is a disease of major public health significance which can be prevented by adequate screening. Objective: This study assessed the level of cervical cancer knowledge, attitude to screening and human papillomavirus testing experience in women who self-sampled for cervical cancer screening. Methods: A descriptive cross-sectional study involving 790 women that had human papilloma virus (HPV) testing at the gynae-oncology unit of the Lagos State University Teaching Hospital. Participants were assessed of their cervical cancer screening knowledge, attitude and HPV testing experience. High risk HPV (hr-HPV) nucleic acid testing was funded by the Clinton Health Access Initiative. Results: Majority (76.71%) of the respondents exhibited a high level of knowledge of cervical cancer, its causes, risk factors and prevention; and a positive experience with HPV self-sampling reported in 98.1%. hr-HPV positive rate was 13.4%. The most common reason (43%) for not having a cervical screening done was lack of a doctor's request. The most commonly known method of cervical screening by the respondents was Pap Smear test (55.31%). Conclusion: There is need for more education to improve the level of awareness and uptake of hr-HPV testing for cervical cancer in Lagos. Health care providers are not offering cervical cancer screening enough and this needs to be explored more in future studies.

A new communication approach to encourage lung cancer screening action in rural eligible populations.

Objective: The purpose of this study was to develop an effective communication approach to encourage lung cancer screening action within rural screening-eligible populations. Methods: An iterative research approach using targeted engagement with the priority population was used. Findings were triangulated through multiple methods, including two surveys and concept testing interviews. The Health Belief Model and the Extended Parallel Process Model served as study frameworks. Results: Initial findings suggest that threat levels are high in the priority population and an emphasis on barrier mitigation messaging may drive action. Health campaign posters integrating these findings were developed and tested with the priority population. The new health campaign posters were tested against examples of previously used health campaign posters. Findings suggest that the new health campaign posters were more effective in spurring lung cancer screening motivation and intention to act in the priority population compared to current health campaign poster examples. Conclusion: Messaging focused on gain-framing, inoculation messaging, and barrier mitigation may be more effective in encouraging lung cancer screening action in rural eligible populations. Innovation: This project outlines a systematic process to developing effective, targeted communication approaches using behavior change and persuasive communication frameworks along with engagement from priority populations.

Alternative endpoints to mortality in cancer screening trials.

The reliance on mortality endpoints in cancer screening trials is not always compatible with the need to accelerate progress in outcomes for patient and public benefit. Evaluation of novel cancer screening technologies, such as multi-cancer early detection (MCED) tests, could be expedited by using alternative metrics that are measurable earlier than mortality. These include endpoints based on cancer stage at diagnosis, such as reduction in late-stage cancer incidence, and endpoints following cancer diagnosis, such as eligibility for curative therapy. Innovative trial designs with earlier measures that complement cancer mortality are needed to realise the potential benefits of novel screening technologies such as MCEDs more rapidly.

Advice after urgent suspected cancer referral when cancer is not found in England: Survey of patients' preferences and perceived acceptability.

Objective: No standardised approach exists to provide advice after urgent suspected cancer (USC) referral when cancer is not found. This study aimed to assess preferences and acceptability of receiving advice after USC referral related to: 1) managing ongoing symptoms, 2) responding to early symptoms of other cancers, 3) cancer screening, 4) reducing risks of future cancer. Methods: 2,541 patients from two English NHS Trusts were mailed a survey 1-3 months after having no cancer found following urgent suspected gastrointestinal or head and neck cancer referral. Participants were asked about: willingness to receive advice; prospective acceptability; preferences related to mode, timing and who should provide advice; and previous advice receipt. Results: 406 patients responded (16.0%) with 397 in the final analyses. Few participants had previously received advice, yet most were willing to. Willingness varied by type of advice: fewer were willing to receive advice about early symptoms of other cancers (88.9%) than advice related to ongoing symptoms (94.3%). Acceptability was relatively high for all advice types. Reducing the risk of future cancer advice was more acceptable. Acceptability was lower in those from ethnic minority groups, and with lower levels of education. Most participants preferred to receive advice from a doctor; with results or soon after; either face to face or via the telephone. Conclusions: There is a potential unmet need for advice after USC referral when no cancer is found. Equitable intervention design should focus on increasing acceptability for people from ethnic minority groups and those with lower levels of education.

Early colorectal cancer screening-no time to lose.

In this editorial, we comment on the article entitled "Stage at diagnosis of colorectal cancer through diagnostic route: Who should be screened?" by Agatsuma et al. Colorectal cancer (CRC) is emerging as an important health issue as its incidence continues to rise globally, adversely affecting the quality of life. Although the public has become more aware of CRC prevention, most patients lack screening awareness. Some poor lifestyle practices can lead to CRC and symptoms can appear in the early stages of CRC. However, due to the lack of awareness of the disease, most of the CRC patients are diagnosed already at an advanced stage and have a poor prognosis.

Knowledge About Cervical Cancer and Awareness About Human Papillomavirus Vaccination Among Medical Students at the Northern Border University, Arar, Kingdom of Saudi Arabia.

Objectives To evaluate the knowledge and awareness about cervical cancer and human papillomavirus (HPV) vaccination among medical undergraduates at Northern Border University. Methods It was a cross-sectional study done on students selected conveniently from the College of Medicine, Northern Border University, Arar. The data were collected regarding knowledge about HPV infection and vaccine awareness using a validated questionnaire. Results A total of 200 students responded to the questionnaires, with 104 (52%) being male students and 120 (60%) being clinical years of MBBS. The mean knowledge score was 17.12 ± 2.73 out of 24, which was labeled as moderate knowledge about cervical cancer and HPV. Almost two-thirds of the students responded correctly to the etiology and risk factors of cervical cancer, while only half of the students knew the correct screening intervals for cervical cancer. The awareness of students about the HPV vaccine was deficient, and the mean score was estimated to be 4.20 ± 0.79 out of nine. Female students and students in clinical years showed significantly better understanding and awareness about cervical cancer and its vaccine and showed greater vaccine acceptability as compared to male students and students in preclinical years. Conclusion The present study shows moderate knowledge about cervical cancer but deficient awareness of medical students about the HPV vaccine. However, the students were willing to get educated about cervical cancer and its vaccine and showed a favorable opinion towards vaccinating the schoolgirls and educating their patients as future physicians. The information can be considered a benchmark on knowledge and awareness levels and can be utilized to modify medical curricula and develop efficient awareness programs.

The edutainment program on knowledge, perception, and uptake of cervical cancer screening among Muslim women in Southern Thailand: a quasi experimental study.

INTRODUCTION: Cervical cancer is a significant global health concern and is the third most common cancer in women. Owing to their religious beliefs, Muslim women in Thailand are less likely to be screened for cervical cancer. OBJECTIVE: This study aimed to explore how a Health Belief Model (HBM) (HBM = Health Belief Model)-Based Edutainment Program affects the knowledge, perception, and uptake of cervical cancer screening among Muslim women in Thailand. METHODS: A quasi-experimental study was conducted in two rural districts of Southern Thailand with 83 Muslim women (intervention = 42, control = 41). The assessment was conducted through face-to-face interviews at baseline, post-intervention, and at 3-month follow-up. The intervention included four sessions involving video clips, folk songs, and short films. Data analysis was performed using repeated-measures ANOVA (ANOVA = Analysis of Variance) at a significance level of 0.05. RESULTS: There were significant differences in the mean score of knowledge and perception between the intervention and control groups post-intervention and at 3-month follow-up (p < 0.001). The mean scores of knowledge and perception in the intervention group significantly increased post-intervention and at 3-month follow-up (p < 0.001). The uptake of cervical cancer screening tests in the intervention group was approximately twice as high as that in the control group (90.47% vs. 51.21%). CONCLUSION: The findings revealed that the Edutainment Program could improve the knowledge, perception, and uptake of cervical cancer screening among Muslim women in Thailand. In future studies, the intervention suggests testing different population groups to improve access to primary care for everyone.

Clinical evaluation of an artificial intelligence-assisted cytological system among screening strategies for a cervical cancer high-risk population.

BACKGROUND: Primary cervical cancer screening and treating precancerous lesions are effective ways to prevent cervical cancer. However, the coverage rates of human papillomavirus (HPV) vaccines and routine screening are low in most developing countries and even some developed countries. This study aimed to explore the benefit of an artificial intelligence-assisted cytology (AI) system in a screening program for a cervical cancer high-risk population in China. METHODS: A total of 1231 liquid-based cytology (LBC) slides from women who underwent colposcopy at the Chinese PLA General Hospital from 2018 to 2020 were collected. All women had received a histological diagnosis based on the results of colposcopy and biopsy. The sensitivity (Se), specificity (Sp), positive predictive value (PPV), negative predictive value (NPV), false-positive rate (FPR), false-negative rate (FNR), overall accuracy (OA), positive likelihood ratio (PLR), negative likelihood ratio (NLR) and Youden index (YI) of the AI, LBC, HPV, LBC + HPV, AI + LBC, AI + HPV and HPV Seq LBC screening strategies at low-grade squamous intraepithelial lesion (LSIL) and high-grade squamous intraepithelial lesion (HSIL) thresholds were calculated to assess their effectiveness. Receiver operating characteristic (ROC) curve analysis was conducted to assess the diagnostic values of the different screening strategies. RESULTS: The Se and Sp of the primary AI-alone strategy at the LSIL and HSIL thresholds were superior to those of the LBC + HPV cotesting strategy. Among the screening strategies, the YIs of the AI strategy at the LSIL + threshold and HSIL + threshold were the highest. At the HSIL + threshold, the AI strategy achieved the best result, with an AUC value of 0.621 (95% CI, 0.587-0.654), whereas HPV testing achieved the worst result, with an AUC value of 0.521 (95% CI, 0.484-0.559). Similarly, at the LSIL + threshold, the LBC-based strategy achieved the best result, with an AUC of 0.637 (95% CI, 0.606-0.668), whereas HPV testing achieved the worst result, with an AUC of 0.524 (95% CI, 0.491-0.557). Moreover, the AUCs of the AI and LBC strategies at this threshold were similar (0.631 and 0.637, respectively). CONCLUSIONS: These results confirmed that AI-only screening was the most authoritative method for diagnosing HSILs and LSILs, improving the accuracy of colposcopy diagnosis, and was more beneficial for patients than traditional LBC + HPV cotesting.

Cancer health awareness through screening and education: A community approach to healthy equity.

BACKGROUND: The Cancer Health Awareness through screeNinG and Education (CHANGE) initiative delivers cancer awareness education with an emphasis on modifiable risk factors and navigation to screening for prostate, breast, and colorectal cancers to residents of public housing communities who experience significant negative social determinants of health. METHODS: Residents of five communities participated. Community advisory board members were recruited and provided feedback to local environmental change projects, recruitment, and community engagement at each site. At each site, four education sessions were provided by trained facilitators on cancer risk factors and etiology, racial disparities, eligibility for cancer screening, and participation in clinical trials. Attendance, knowledge, attitudes and beliefs about cancer, and height, weight, and waist circumference were measured at baseline and 1-week post-CHANGE sessions. RESULTS: 90 residents (60% 65 and older years old, 33% male, 60% High School education, 93% AA) participated in the program. 95% completed post-intervention evaluation. Participants were eligible for breast (n = 12), prostate (n = 15), and colorectal screening (n = 25) based on American Cancer Society guidelines, and 22 for tobacco cessation; 21 participants accepted navigation assistance for these services. At post-test, participants significantly increased in knowledge and behaviors around obesity/overweight risk for cancer, nutrition, and physical activity. Colorectal, prostate, and breast cancer knowledge scores also increased, but were not significant. CONCLUSIONS: CHANGE participants demonstrated improved health knowledge and intentions to improve their modifiable health behaviors. Participants reported being motivated and confident in seeking preventive care and satisfaction with community engagement efforts. Replication of this project in similar communities may improve knowledge and health equity among underserved populations.

Tobacco quitline staffs' knowledge and attitudes about connecting quitline callers to lung cancer screening educational materials.

OBJECTIVE: To evaluate the impact of training quitline staff in lung cancer screening (LCS) on knowledge and attitudes towards connecting quitline callers to LCS educational materials. METHODS: We conducted a pre-post evaluation within a larger implementation project in the U.S. to support LCS among quitline callers. From July 2020 to June 2021, staff from four quitline service providers completed surveys before and after training on LCS knowledge. After training, staff completed the acceptability of intervention measure, intervention appropriateness measure, and feasibility of the intervention measure. RESULTS: A total of 245 staff completed the initial demographic survey (analytic sample), 130 completed the pre-training survey, and 225 completed the post-training survey. Staff were on average 47.4 years old and 76.7% were female. LCS knowledge improved after the training (n = 120, mean difference = +26.5%, 95% CI 21.6, 31.4, p < 0.001). Overall, staff felt that connecting quitline callers to LCS education materials was acceptable (M = 4.0, SD = 0.8), appropriate (M = 4.1, SD = 0.7), and feasible (M = 4.0, SD = 0.7). CONCLUSIONS: Receiving training about LCS eligibility and the benefits and harms of screening improved LCS knowledge among quitline staff. Quitline staff found that connecting callers with LCS educational materials is acceptable, appropriate, and feasible, and aligned with their primary mission.

Uptake of cervical cancer screening and associated factors among HIV positive women attending adult art clinic at public hospitals in Addis Ababa, Ethiopia, 2022.

BACKGROUND: Cervical cancer is the second most common malignancy in Ethiopia and first in some African countries. It is six times more likely to occur in positive cases of the human immunodeficiency virus than in the general population. If diagnosed and treated early enough, cervical cancer is both treatable and preventable. However, among Ethiopian women who test positive for HIV, the uptake of cervical cancer screening is low. Its determinant factors were not well studied in the study area. Hence, this study was aimed at filling this information gap. OBJECTIVE: To assess uptake of cervical cancer screening services and associated factors among HIV-positive women attending an adult antiretroviral treatment clinic at public hospitals in Addis Ababa, Ethiopia, June 1-30, 2022. METHODS: A cross-sectional investigation was carried out in a hospital. 407 participants in all were chosen using the systematic sampling technique. A pretested interviewer-administered questionnaire was used to collect the data from respondents. The data were entered into Epi data version 4.6 and exported to SPSS version 25 for analysis. Bivariable and multivariable logistic regression analysis was employed. Adjusted odds ratio with its 95% confidence interval and p value < 0.05 were used to estimate the strength and significance of the association. RESULT: Among a total of 407 respondents, 238 (58.5%), 95% CI (53.5-63.3), HIV-positive women were screened at least once in the last five years. In multivariable analysis, age > 45 years old (AOR = 0.18, 95% CI: 0.053-0.644), number of children (3 children) (AOR = 0.19, 95% CI:0.036-0.979), perception of being susceptible to cervical cancer (AOR = 6.39, 95% CI: 1.79-22.74), knowledge of cervical cancer and its screening (AOR = 19.34, 95% CI: 7.87-47.75), and positive attitude towards cervical cancer screening (AOR = 8.06, 95% CI:3.62-17.91) were significantly associated factors with the uptake of cervical cancer screening. CONCLUSION AND RECOMMENDATION: in this study, Age > 45 years, having less than three children, feeling susceptible, knowing about cervical cancer and screening, and having a positive attitude toward cervical cancer screening were significant factor of uptake of cervical cancer screening service. There is a need to strengthen the policy and health education on safe sexual practices and healthy lifestyles through information dissemination and communication to scale up screening service utilization.

Stakeholder perceptions of cervical screening accessibility and attendance in Ireland: a qualitative study.

Organized cervical screening programmes are commonplace in high-income countries. To provide an equitable cervical screening service, it is important to understand who is and is not attending screening and why. Promotion of screening and service improvement is not possible without recognition and identification of the barriers and needs of communities that are less engaged with screening. This study explored stakeholder perceptions of cervical screening attendance and accessibility in Ireland. Semi-structured interviews were conducted with 12 healthcare professionals, policymakers and academics. Interviews were conducted online in 2022. Reflexive thematic analysis was used inductively to generate themes, supported by NVivo. Three themes were developed: (i) getting the right information out the right way, (ii) acceptability and accessibility of screening and (iii) trying to identify and reach the non-attenders. Participants felt public knowledge of cervical screening and human papilloma virus was low and communication strategies were not adequate. Individual, cultural, structural and service-level factors influenced the accessibility and acceptability of screening. Identifying and reaching non-attenders was considered challenging and community outreach could support those less likely to attend screening. Stakeholder perspectives were valuable in understanding the complexities of screening accessibility and attendance from individual to service-level factors. Cultural competency training, inclusive language and visual cues in waiting rooms would support engagement with some populations who may be hesitant to attend screening. Collaboration with community organizations has opportunities to promote screening and understand the needs of those less likely to attend screening.

Access to Cancer Care: Prevention and Screening for Females Post Kidney Transplantation Around the World.

Kidney transplantation offers recipients superior outcomes and improved quality of life compared with dialysis. However, the need for ongoing immunosuppression places recipients at increased risk of certain forms of cancer. Screening and early detection of precancerous lesions are one of the few proven ways to lower the risk of cancer morbidity and mortality in the transplant population. Women have additional barriers to cancer screening services globally, especially in low- and middle-income countries as well as within certain disadvantaged groups in high-income countries. There is a dearth of published data on screening guidelines and policies on post-transplant malignancy in female recipients. It is vital that health care providers and patients are educated regarding the risks of cancer at all post-transplant stages and that the recommended screening policies are adhered to in order to reduce associated morbidity and mortality in this at-risk group.

Development of an Electronic Health Record Self-Referral Tool for Lung Cancer Screening: One-Group Posttest Study.

BACKGROUND: Approximately 14 million individuals in the United States are eligible for lung cancer screening (LCS), but only 5.8% completed screening in 2021. Given the low uptake despite the potential great health benefit of LCS, interventions aimed at increasing uptake are warranted. The use of a patient-facing electronic health record (EHR) patient portal direct messaging tool offers a new opportunity to both engage eligible patients in preventative screening and provide a unique referral pathway for tobacco treatment. OBJECTIVE: This study sought to develop and pilot an EHR patient-facing self-referral tool for an established LCS program in an academic medical center. METHODS: Guided by constructs of the Health Belief Model associated with LCS uptake (eg, knowledge and self-efficacy), formative development of an EHR-delivered engagement message, infographic, and self-referring survey was conducted. The survey submits eligible self-reported patient information to a scheduler for the LCS program. The materials were pretested using an interviewer-administered mixed methods survey captured through venue-day-time sampling in 5 network-affiliated pulmonology clinics. Materials were then integrated into the secure patient messaging feature in the EHR system. Next, a one-group posttest quality improvement pilot test was conducted. RESULTS: A total of 17 individuals presenting for lung screening shared-decision visits completed the pretest survey. More than half were newly referred for LCS (n=10, 60%), and the remaining were returning patients. When asked if they would use a self-referring tool through their EHR messaging portal, 94% (n=16) reported yes. In it, 15 participants provided oral feedback that led to refinement in the tool and infographic prior to pilot-testing. When the initial application of the tool was sent to a convenience sample of 150 random patients, 13% (n=20) opened the self-referring survey. Of the 20 who completed the pilot survey, 45% (n=9) were eligible for LCS based on self-reported smoking data. A total of 3 self-referring individuals scheduled an LCS. CONCLUSIONS: Pretest and initial application data suggest this tool is a positive stimulus to trigger the decision-making process to engage in a self-referral process to LCS among eligible patients. This self-referral tool may increase the number of patients engaging in LCS and could also be used to aid in self-referral to other preventative health screenings. This tool has implications for clinical practice. Tobacco treatment clinical services or health care systems should consider using EHR messaging for LCS self-referral. This approach may be cost-effective to improve LCS engagement and uptake. Additional referral pathways could be built into this EHR tool to not only refer patients who currently smoke to LCS but also simultaneously trigger a referral to clinical tobacco treatment.
