Functional outcomes after localized prostate cancer treatment.
The objective of this observational cohort study was to compare rates of adverse functional outcomes between specific treatments for localized prostate cancer. Researchers used data from five U.S. Surveillance, Epidemiology, and End Results Program registries. Participants were patients treated for localized prostate cancer in 2011-2012. The results indicated that radical prostatectomy was associated with worse urinary incontinence, but not with worse sexual function, at 10-year followup when compared with radiotherapy or surveillance. Among patients with unfavorable-prognosis disease, external beam radiotherapy with androgen deprivation therapy was associated with worse bowel and hormone function at 10-year followup compared with radical prostatectomy.

The SIMPLE architectural pattern for integrating patient-facing apps into clinical workflows: desiderata and application for lung cancer screening.
To address the need for electronic health record (EHR) systems to accept the connection of any patient-facing digital health app using the SMART on FHIR standard, the authors proposed the Standards-based Implementation Maximizing Portability Leveraging the EHR (SIMPLE). SIMPLE’s architectural pattern was designed to meet several key requirements, such as not requiring patients to install new software; not retaining patient data outside of the EHR; leveraging existing personal health record (PHR) capabilities to optimize user experience; and maximizing portability.

CancelRx case study: implications for clinic and community pharmacy work systems.
This study examined the impact of implementation of CancelRx, a health IT system that automatically communicates medication discontinuations from the clinic electronic health record to the community pharmacy dispensing platform, theoretically improving communication. The system was implemented across a Midwest academic health system in October 2017, using their 15 outpatient community pharmacies to test it. Interviews were conducted with 9 medical assistants, 12 community pharmacists, and 3 pharmacy administrators employed by the health system across 3-time periods between 2017 and 2018: 3-months prior to CancelRx implementation, 3-months after CancelRx implementation, and 9-months after CancelRx implementation. While CancelRx automated and streamlined how medication discontinuation messages were received and processed, it also increased workload and introduced new errors.

Abnormal cervical cancer screening results among US veteran and non-veteran participants in the National Health Interview Survey (NHIS).
Researchers tested whether Veterans with a recent cervical cancer screening test were more likely than non-Veterans to have received an abnormal result. Data was taken from the National Health Interview Survey (NHIS). An adjusted regression model of the date indicated that a previously observed association between Veteran status and abnormal screening result was explained by differences in sociodemographic and health factors between Veterans and non-Veterans. The researchers concluded that clinicians should address modifiable risk factors and provide evidence-based follow-up for abnormal results.

Prostate volume, baseline urinary function, and their association with treatment choice and post-treatment urinary function in men treated for localized prostate cancer.
The purpose of this study was to assess the relationship between prostate volume (PV) and baseline urinary function with treatment choice and post-treatment urinary function among men with localized prostate cancer. The researchers identified 1,647 patients from CEASAR, a multicenter population-based, prospective cohort study of men with localized prostate cancer. The primary study outcomes were treatment choice and health-related quality of life (HRQOL) assessed at pre-specified intervals up to 5 years. The study found that median baseline PV was 36 mL (IQR 27-48), and baseline urinary irritative/obstructive domain score was 87 (IQR 75-100). The study did not find any observed clinically meaningful relationship between PV and treatment choice or post-treatment urinary function. In participants with poor baseline urinary function, treatment with radiation or surgery was related with statistically and clinically significant improvement in urinary function at 6 months which endured through 5 years.

The decision aid is the easy part: workflow challenges of shared decision making in cancer care.
The authors indicate that widespread use of shared decision making (SDM) in clinical care has been limited even though both the National Academy of Medicine and the American Society of Clinical Oncology recommend SDM methods to improve patient-centered care. The purpose of this commentary is to explore 3 workflow-related barriers to SDM, and to discuss human factors engineering and demonstrate its potential value to decision aid design through a decision-making case study.

Automated opt-out vs opt-in patient outreach strategies for breast cancer screening: a randomized clinical trial.
The objective of this study was to evaluate the effect on breast cancer screening of an opt-out automatic mammography referral strategy compared with an opt-in automated telephone message strategy. Participants in the pragmatic randomized clinical trial, conducted at a Veterans Affairs (VA) medical center, were female veterans aged 45-75 eligible for breast cancer screening and enrolled in VA primary care. The results indicated that the opt-out population-based breast cancer screening outreach approach compared with an opt-in approach did not result in a significant difference in mammography completion, but did lead to more canceled mammography referrals, which increased staff burden.

Considerations for using predictive models that include race as an input variable: the case study of lung cancer screening.
Indiscriminate use of predictive models incorporating race can reinforce biases present in source data and lead to an exacerbation of health disparities. In some countries, such as the United States, there is therefore a push to remove race from prediction models; however, there are still many prediction models that use race as an input. Biomedical informaticists who are given the responsibility of using these predictive models in healthcare environments are likely to be faced with questions like how to deal with race covariates in these models. The authors report that there is a need for a practical framework to facilitate model user thinking on how to incorporate race in their chosen model to avoid inadvertently amplifying disparities. The purpose of this paper is to utilize a case study of lung cancer screening to propose a simple framework to guide model users in approaching race inputs in the predictive models they are attempting to leverage in electronic health records and clinical workflows.

Evaluation of nationwide trends in nodal sampling guideline adherence for gastric cancer: 2005-2017.
This study’s purpose was to evaluate trends in program-level disparities in adherence to gastric cancer nodal sampling guidelines. The cohort included 55,421 patients who underwent resection of gastric cancer from 2005 to 2017 identified in the National Cancer Database. Of that total 27,201 (49.1%) of patients met adherence criteria for lymph node sampling. Academic hospitals treated 44.4% of the total cohort. Overall, lymph node sampling criteria were met in 59.2% of patients treated at high-volume academic programs and 37.0% of patients treated at low-volume nonacademic programs. Adherence rates improved overall from 2005 to 2017 for both low-volume nonacademic programs (27.8% in 2005 to 50.1% in 2017) and high-volume academic programs (46.0% in 2005 to 69.8% in 2017).

Impact of BMI on prevalence of dense breasts by race and ethnicity.
Researchers evaluated differences in body mass index (BMI) in relation to differences in dense breasts prevalence by race/ethnicity. Their results indicated that dense breasts were most prevalent among Asian women followed by non-Hispanic White, Hispanic, and Black women. Clinically important differences in breast density prevalence are present across racial/ethnic groups after accounting for age, menopausal status, and BMI. IMPACT: If breast density is the sole criterion used to notify women of dense breasts and discuss supplemental screening it may result in implementing inequitable screening strategies across racial/ethnic groups.

Implementation of lung cancer screening in primary care and pulmonary clinics: pragmatic clinical trial of electronic health record-integrated everyday shared decision-making tool and clinician-facing prompts.
The authors conducted pre- and post-intervention analysis in primary care and pulmonary clinics to explore whether clinician-facing electronic health record (EHR) prompts and an EHR-integrated shared decision-making (SDM) tool designed to support incorporation of SDM into primary care could improve low-dose computer tomography scan imaging ordering and completion. Subjects were patients who met US Preventive Services Task Force criteria for lung cancer screening (LCS). The results indicated that EHR prompts and the EHR-integrated SDM tool were promising approaches to improving LCS in the primary care setting. The authors noted that further research is warranted.

The thoracic research evaluation and treatment 2.0 model: a lung cancer prediction model for indeterminate nodules referred for specialist evaluation.
In this research study the authors updated and expanded the Thoracic Research Evaluation and Treatment (TREAT) model into a more generalized, robust approach for lung cancer prediction in patients referred for specialty evaluation to improve lung cancer prediction accuracy. Clinical and radiographic data on 1401 patients with indeterminate pulmonary nodules (IPNs) from six sites were collected retrospectively and divided into groups by clinical setting: pulmonary nodule clinic (n = 374; cancer prevalence, 42%), outpatient thoracic surgery clinic (n = 553; cancer prevalence, 73%), or inpatient surgical resection (n = 474; cancer prevalence, 90%). The new prediction model was developed using a missing data-driven pattern submodel approach and compared with the original TREAT, Mayo Clinic, Herder, and Brock models. Two-thirds of patients were found to have missing data; nodule growth and fluorodeoxyglucose-PET scan avidity were missing most frequently. The TREAT version 2.0 mean area under the receiver operating characteristic curve across missingness patterns was 0.85 compared with the original TREAT (0.80), Herder (0.73), Mayo Clinic (0.72), and Brock (0.68) models with improved calibration.

Assessing characteristics of populations seen at Commission on Cancer facilities using Pennsylvania linked data.
The purpose of this study was to evaluate variations among patients who do and do not visit Commission on Cancer (CoC) accredited facilities. The researchers utilized Pennsylvania Cancer Registry data linked to facility records for 87,472 patients diagnosed with cancer between 2018 and 2019. The study found that patients in the most advantaged Area Deprivation Index quartiles were more likely to visit CoC facilities compared with other quartiles. Urban patients were more likely than rural to be seen at a CoC facility as were Hispanic patients and non-Hispanic Black patients compared with White patients.

Clinical implications of removing race-corrected pulmonary function tests for African American patients requiring surgery for lung cancer.
This study’s objective was to identify how many hospitals providing lung cancer surgery use race correction in pulmonary function tests (PFTs), examine the association of race correction with predicted lung function, and test the effect of decorrection on surgeons' treatment recommendations. Percent predicted preoperative and postoperative forced expiratory volume in 1 second (FEV1) was calculated for African American patients who underwent lung cancer resection between January 1, 2015, and September 31, 2022, using race-corrected and race-neutral equations for hospitals performing race correction. Randomization of US cardiothoracic surgeons was conducted to receive 1 clinical vignette that differed by the use of Global Lung Function Initiative equations for (1) African American patients (percent predicted postoperative FEV1, 49%), (2) other race or multiracial patients (percent predicted postoperative FEV1, 45%), and (3) race-neutral patients (percent predicted postoperative FEV1, 42%). A total of 515 African American patients (308 [59.8%] female; mean age, 66.2 years) were included in the study. Among these patients, the percent predicted preoperative FEV1 and postoperative FEV1 would have decreased by 9.2% and 7.6%, respectively, if race-neutral equations had been used. A total of 225 surgeons (194 male [87.8%]; mean time in practice, 19.4 years) were successfully randomized and completed the vignette items regarding risk perception and treatment outcomes (76% completion rate). Surgeons randomized to the vignette with African American race-corrected PFTs were more likely to recommend lobectomy (79.2%) compared with surgeons randomized to the other race or multiracial-corrected (61.7%) or race-neutral PFTs (52.8%).

Evolving variation in the extent of surgery for low-risk papillary thyroid cancer in the United States.
This study looked at contemporary trends in the extent of surgery in patients with clinically node-negative papillary thyroid cancer ≤4 cm. Since 2015 there has been a debate over total thyroidectomy versus lobectomy and declining favor for prophylactic central neck dissection in this low-risk cohort. The authors used retrospective data from the National Cancer Database to identify adult patients with clinically node-negative papillary thyroid cancer ≤4 cm who underwent resection from 2012 to 2020. Primary outcome was the extent of surgery (lobectomy or total thyroidectomy, with or without prophylactic central neck dissection). Of 83,464 included patients, 79.3% were female with a median age of 51 years. Most patients underwent total thyroidectomy either with prophylactic central neck dissection (39.1%) or without (37.5%) versus lobectomy with prophylactic central neck dissection (7.2%) or without (16.2%). There was an increase in lobectomy from 18.3% in 2012 to 29.9% in 2020. Prophylactic central neck dissection rates also increased from 42.9% to 52.1%. There was a decreased likelihood of total thyroidectomy in patients who were male sex, Asian American, had smaller tumors or were treated at community cancer programs. There was a decreased likelihood of prophylactic central neck dissection in patients who were older, male sex, Black race, with smaller tumors, or were treated at community cancer programs or mid- or low-volume facilities.

Performance of the shared decision-making process scale for use in evaluation of hereditary cancer genetic testing decisions.
This study’s objective was to evaluate the feasibility, acceptability, reliability, and validity of the four-item Shared Decision Making (SDM) Process Scale for use in for hereditary cancer genetic testing decision-making. Participants were patients from a large hereditary cancer genetics practice who responded to an online survey following pre-test genetic counseling; the survey included the SDM Process Scale and the SURE scale. The SDM Process Scale showed feasibility, acceptability, and retest reliability, but not convergent validity with decisional conflict. The authors concluded that their findings provided evidence for use of this scale to measure patient perceptions of SDM in pre-test counseling.

Surgical versus non-surgical management for patients with malignant bowel obstruction (S1316): a pragmatic comparative effectiveness trial.
The purpose of this study was to compare surgical versus non-surgical management with the goal of determining the optimal approach for managing malignant bowel obstruction. From May 11, 2015, to April 27, 2020, 221 patients were enrolled, with 199 evaluable participants. The study found no variation between surgery and non-surgery for the primary outcome of good days: mean 42·6 days in the randomized surgery group, 43·9 days (29·5) in the randomized non-surgery group, 54·8 days (27·0) in the patient choice surgery group, and 52·7 days (30·7) in the patient choice non-surgery group. During their initial hospital stay, six participants died, five due to cancer progression and one due to malignant bowel obstruction treatment complications The most common grade 3-4 malignant bowel obstruction treatment complication was anemia.

Organization of cancer specialists in US physician practices and health systems.
This study’s objective was to describe the supply of cancer specialists, the organization of cancer care within versus outside of health systems, and the distance to multispecialty cancer centers. The authors used the 2018 Health Systems and Provider Database from the National Bureau of Economic Research and 2018 Medicare data to identify 46,341 unique physicians providing cancer care. They stratified physicians by discipline (adult/pediatric medical oncologists, radiation oncologists, surgical/gynecologic oncologists, other surgeons performing cancer surgeries, or palliative care physicians), system type (National Cancer Institute [NCI] Cancer Center system, non-NCI academic system, nonacademic system, or nonsystem/independent practice), practice size, and composition (single disciplinary oncology, multidisciplinary oncology, or multispecialty). They computed the density of cancer specialists by county and calculated distances to the nearest NCI Cancer Center. Results found that more than half of all cancer specialists (57.8%) practiced in health systems, but 55.0% of cancer-related visits occurred in independent practices. A majority of system-based physicians were in large practices with more than 100 physicians, while those in independent practices were in smaller practices. Breakdown by specialty type showed that practices in NCI Cancer Center systems (95.2%), non-NCI academic systems (95.0%), and nonacademic systems (94.3%) were primarily multispecialty, while fewer independent practices (44.8%) were. Many rural areas had sparse cancer specialty density, where the median travel distance to an NCI Cancer Center was 98.7 miles. Higher-income areas had shorter distances to NCI Cancer centers than low-income areas, even for individuals in suburban and rural areas.

Comparison of primary payer in cancer registry and discharge data.
The purpose of this cross-sectional study was to ascertain agreement between variables capturing the primary payer at cancer diagnosis across the Pennsylvania Cancer Registry (PCR) and statewide facility discharge records (Pennsylvania Health Care Cost Containment Council [PHC4]) for adults under 65 years, and to examine variables related with misclassification of Medicaid status in the registry given the role of managed care. The researchers evaluated agreement of payer at diagnosis across data sources. The study found that agreement of payers was high for private insurance, but there was misclassification and/or underreporting of Medicaid in the registry. Among cases with "other" and "unknown" insurance, 73.8% and 62.1%, respectively, had private insurance. Medicaid managed care was related with a statistically significant increase of 12.6 percentage points in the probability of misclassifying Medicaid enrollment as private insurance in the registry.

Factors associated with lung cancer risk factor documentation.
This cross-observational study’s objective was to identify factors associated with the minimum necessary information to determine an individual’s eligibility for lung cancer screening (ie, sufficient risk factor documentation) and to characterize clinic-level variability in documentation. The authors calculated the relative risk of sufficient lung cancer risk factor documentation by patient-, provider-, and system-level variables using Poisson regression models, clustering by clinic. They compared unadjusted, risk-adjusted, and reliability-adjusted proportions of patients with sufficient smoking documentation across 31 clinics using logistic regression models and 2-level hierarchical logit models to estimate reliability-adjusted proportions across clinics. A majority (60%) of 20,632 individuals were found to have sufficient risk factor documentation to determine screening eligibility. Patient-level factors were inversely associated with risk factor documentation including Black race, non-English preferred language, Medicaid insurance, and nonactivated patient portal, with documentation varying across clinics.

Frequency and outcomes of BI-RADS category 3 assessments in patients with a personal history of breast cancer: full-field digital mammography versus digital breast tomosynthesis.
The purpose of this article was to compare the frequency, outcomes, and additional characteristics of BI-RADS category 3 assessments between full-field digital mammography (FFDM) and digital breast tomosynthesis (DBT) in patients with a personal history of breast cancer (PHBC). This retrospective study examined electronic health records from 14,845 mammograms in 10,118 patients (mean age, 63 years) with PHBC who had undergone mastectomy and/or lumpectomy. Of these, 8422 examinations were performed by FFDM from October 2014 to October 2016 and the rest examinations by FFDM with DBT from February 2017 to December 2018. The frequency of category 3 assessment was lower for DBT than FFDM (5.6% vs 6.4%). DBT, compared with FFDM, showed a lower malignancy rate for category 3 lesions (1.8% vs 5.0%), higher malignancy rate for category 4 lesions (32.0% vs 23.2%), and no difference in malignancy rate for category 5 lesions (100.0% vs 75.0%). An analysis of index category 3 lesions included 438 lesions for FFDM and 274 lesions for DBT. For category 3 lesions, DBT, compared with FFDM, showed lower PPV3 (13.9% vs 36.1%) and a more frequent mammographic finding of mass (33.2% vs 23.1%).

Methods for using race and ethnicity in prediction models for lung cancer screening eligibility.
The purpose of this study was to compare eligibility for lung cancer screening in a representative United States population by refitting the life-years gained from screening-computed tomography (LYFS-CT) model to exclude race and ethnicity versus a counterfactual eligibility method that recalculates life expectancy for racial and ethnic minority individuals utilizing the same covariates but substitutes White race and utilizes the higher predicted life expectancy, preventing historically underserved groups from being penalized. The National Health Interview Survey (NHIS) 2015-2018 included 25,601 individuals aged 50 to 80 years who ever smoked. The study found that removing race and ethnicity from the submodels underestimated lung cancer death risk and all-cause mortality in African American individuals. It also overestimated mortality in Hispanic American and Asian American individuals. As a result, the LYFS-CT NoRace model increased Hispanic American and Asian American eligibility by 108% and 73%, respectively, while decreasing African American eligibility by 39%. Utilizing LYFS-CT with the counterfactual all-cause mortality model better maintained calibration across groups and increased African American eligibility by 13% without decreasing eligibility for Hispanic American and Asian American individuals.

Opportunities for savings in risk arrangements for oncologic care.
High spending for cancer care is a target for savings as the United States hastens adoption of alternative payment through global payment models such as Accountable Care Organizations (ACOs) or Medicare Advantage (MA). The purpose of this study was to quantify the level at which Accountable Care Organizations ACOs and other risk-bearing organizations operating in a specific geographic area could realize savings by directing patients to efficient medical oncology practices. The incident cohort included 1,309,825 patients Options for directing differed across markets; the top quartile market had 10 or more oncology practices, but the bottom quartile had 3 or fewer oncology practices. Total spending (including Medicare Part D) in the incident cohort increased from a mean of $57,314 in 2009 to 2010 to $66,028 in 2016 to 2017. Within markets, total spending for practices in the highest spending quartile was 19% greater than in the lowest quartile. Hospital spending was the single largest component of spending in both time periods followed by Part B (infused) chemotherapy. Correlations in practice-level spending between the first-year (2009) and second-year (2010) spending were high.

Developing electronic clinical quality measures to assess the cancer diagnostic process.
Electronic clinical quality measures (eCQMs) to evaluate quality of cancer diagnosis could facilitate quantification and improvement of diagnostic performance. The purpose of this study was to developed 2 eCQMs to evaluate diagnostic assessment of red-flag clinical findings for colorectal cancer (CRC) and lung cancer. At each site the researchers assessed 100 positive and 20 negative randomly chosen records for each eCQM at each site to validate accuracy and categorized missed opportunities associated with system, provider, or patient factors. The researchers applied the CRC eCQM at both sites, while the lung cancer eCQM was only applied at the VA due to an absence of structured data indicating level of cancer suspicion on most chest imaging results at Geisinger. The study found that for the CRC eCQM, the appropriate follow-up took place in 26, 746 out of 74, 314 patients (36.0%) in the VA after removing clinical exclusions and in 1,009 out of 2,461 patients (41.1%) at Geisinger. The appropriate assessment for lung cancer in the VA took place in 25, 166 out of 40, 924 patients (61.5). Provider factors were cited by reviewers the primary source of missed opportunities at both sites.

Breast cancer risk characteristics of women undergoing whole-breast ultrasound screening versus mammography alone.
This study evaluated mammography screening failure risk among women undergoing supplemental ultrasound screening in clinical practice in comparison with women undergoing mammography alone. Screening ultrasounds and screening mammograms without supplemental screening were identified within three Breast Cancer Surveillance Consortium registries. A clinically significant proportion of women who had undergone mammography screening alone were at high mammography screening failure risk. Ultrasound screening was highly targeted to women with dense breasts, but only a small proportion were high mammography screening failure risk.
