Social Determinants of Health in Oncology: Towards a More Personalized and Equitable Delivery of Cancer Care

Impact of Hospital Volume on Survival for Pediatric Wilms Tumor

BACKGROUND

Treatment for children with Wilms tumor (WT) is multidisciplinary, often including surgery, chemotherapy, and sometimes radiation therapy. High-volume hospitals (HVH) have been associated with improved outcomes in cancer care. Our study evaluates the association of hospital volume and survival outcomes in pediatric WT management.

PROCEDURE

Patients ≤18 years undergoing surgery for WT were identified from the National Cancer Database (2004-2020). A restricted cubic spline model assessed the association between hospital volume and 5-year survival. An extrapolated hospital volume cutoff was validated through Kaplan-Meier curves and Cox regression and applied to compare demographics, tumor characteristics, and treatment differences between HVH and low-volume hospitals (LVH).

RESULTS

Among 3424 patients, higher hospital volume was associated with improved survival, with no additional survival benefit beyond three cases per year. Using this as a cutoff, 11/227 institutions qualified as HVH, treating 696 patients (20.3%). Kaplan-Meier analysis supported this cutoff, showing a higher 5-year survival for HVH (95.5% vs. 93.1%, p = 0.024), while multivariable analysis associated HVH treatment with reduced mortality (aHR 0.71, 95% CI: 0.54-0.93). Compared to HVH, LVH-treated patients were more likely to be Hispanic (14.0% vs. 12.0%, p = 0.002), live closer to the treating facility (29 vs. 39 km, p < 0.0001), have fewer bilateral tumors (5.7% vs. 7.6%, p = 0.03), and receive less frequent lymph node sampling (81.6% vs. 88.9%, p < 0.0001) and chemotherapy (90.4% vs. 94.4%, p = 0.003).

CONCLUSION

In pediatric WT treatment, HVH treatment was associated with superior survival outcomes and greater adherence to lymph node sampling. To improve outcomes at LVH, additional training for clinicians at HVH could enhance guideline adherence and integrate effective practices.

Disparities in Musculoskeletal Oncology

PURPOSE OF REVIEW

Disparities within the healthcare system serve as barriers to care that lead to poor outcomes for patients. These healthcare disparities are present in all facets of medicine and extend to musculoskeletal oncology care. There are various tenets to health disparities with some factors being modifiable and non-modifiable. The factors play a direct role in a patient's access to care, time of presentation, poor social determinants of health, outcomes and survival.

RECENT FINDINGS

In musculoskeletal oncologic care, factors such as race, socioeconomic factors and insurance status are correlated to advanced disease upon presentation and poor survival for patients with a sarcoma diagnosis. These factors complicate the proper delivery of coordinated care that is required for optimizing patient outcomes. Healthcare disparities lead to suboptimal outcomes for patients who require musculoskeletal oncologic care in the short and long term. More research is required to identify ways to address the known modifiable and non-modifiable factors to improve patient outcome.

Supportive care needs among older Mexican adults with metastatic cancer

INTRODUCTION

Supportive care needs may vary according to age. The purpose of this research is to describe and compare supportive care needs between older adults with metastatic cancer (age ≥ 65 years) and their younger counterparts.

MATERIALS AND METHODS

We conducted a retrospective secondary analysis of a cohort of patients with newly diagnosed metastatic solid tumors. Supportive care needs were assessed at baseline and at a three-month follow-up. Patients were divided into two groups (aged ≥65/<65 years). Differences in clinical characteristics and supportive care needs were compared utilizing descriptive statistics. Multivariate logistic regression models were employed to identify patient characteristics associated with specific supportive care needs.

RESULTS

Between 2018 and 2022, 375 patients were enrolled. Median age was 66 years (interquartile range 19-94). At baseline, older adults had a higher number of supportive care needs (4.8 vs. 4.2, p = 0.01) and were at higher risk of malnutrition (75 vs. 65%, p = 0.05). Increasing age (odds ratio [OR] 1.02 (95% confidence interval [CI] 1.0-1.04, p = 0.03) and an estimated life expectancy <6 months (OR 3.0, 95%CI 1.5-6.1; p < 0.01) were associated with higher odds of malnutrition, while a higher educational level was associated with decreased odds (OR 0.68, 95%CI 0.5-0.8; p < 0.01). At three-month follow-up, older adults still had a higher number of supportive care needs (3.8 vs.2.6, p < 0.01) and were more likely to have fatigue (62 vs. 47%, p = 0.02). An estimated life expectancy of <6 months was associated with increased odds of fatigue (OR 3.0, 95%CI 1.5-6.3; p < 0.01).

DISCUSSION

Older adults reported significantly more supportive care needs, particularly risk of malnutrition and fatigue. This information can help in the creation of supportive care services tailored to the needs of older individuals.

High Community-Level Social Vulnerability is Associated with Worse Recurrence-Free Survival (RFS) After Resection of Extremity and Truncal Soft Tissue Sarcoma

BACKGROUND

Although social vulnerability has been associated with worse postoperative and oncologic outcomes in other cancer types, these effects have not been characterized in patients with soft tissue sarcoma. This study evaluated the association of social vulnerability and oncologic outcomes.

METHODS

The authors conducted a single-institution cohort study of adult patients with primary and locally recurrent extremity or truncal soft tissue sarcoma undergoing resection between January 2016 and December 2021. The social vulnerability index (SVI) was measured on a low (SVI 1-39%, least vulnerable) to high (60-100%, most vulnerable) SVI scale. The association of SVI with overall survival (OS) and recurrence-free survival (RFS) was evaluated by Kaplan-Meier analysis and Cox proportional hazard regression.

RESULTS

The study identified 577 patients. The median SVI was 44 (interquartile range [IQR], 19-67), with 195 patients categorized as high SVI and 265 patients as low SVI. The median age, tumor size, histologic subtype, grade, comorbidities, stage, follow-up time, and perioperative chemotherapy and radiation utilization were similar between the high and low SVI cohorts. The patients with high SVI had worse OS (p = 0.07) and RFS (p = 0.016) than the patients with low SVI. High SVI was independently associated with shorter RFS in the multivariate analysis (hazard ratio, 1.64; 95% confidence interval, 1.06-2.54) but not with OS (HR, 1.47; 95% CI 0.84-2.56).

CONCLUSION

High community-level social vulnerability appears to be independently associated with worse RFS for patients undergoing resection of extremity and truncal soft tissue sarcoma. The effect of patient and community-level social risk factors should be considered in the treatment of patients with extremity sarcoma.

Neighborhood Deprivation and Symptoms, Psychological Distress, and Quality of Life Among Head and Neck Cancer Survivors

Importance

Socioeconomic deprivation is associated with increased risk of poor health and quality-of-life (QOL) outcomes in head and neck cancer (HNC) survivors. However, there are few data on how neighborhood deprivation affects patient-reported outcome measures (PROMs) in HNC survivors.

Objective

To investigate whether neighborhood socioeconomic deprivation is associated with symptom burden, psychological distress, and QOL among HNC survivors.

Design, Setting, and Participants

This cross-sectional study used prospectively collected data from patients seen in a university-affiliated multidisciplinary HNC survivorship clinic between September 2018 and September 2021 who received radiotherapy for squamous cell carcinoma of the oral cavity, oropharynx, and larynx or hypopharynx.

Exposure

Neighborhood socioeconomic deprivation, measured using the Area Deprivation Index (ADI).

Main Outcomes and Measures

The PROMs pertaining to symptom burden and severity of psychological distress were measured using the Neck Disability Index, Insomnia Severity Index, the 10-item Eating Assessment Tool, the Generalized Anxiety Disorder 7-item scale, and the 8-item Patient Health Questionnaire. Physical and social-emotional QOL were obtained using the University of Washington QOL questionnaire. Multivariable linear regression analysis adjusting for individual-level sociodemographic, comorbidity, and treatment characteristics investigated the association between ADI and PROMs. A subgroup analysis was performed to compare the lowest (most affluent areas: ADI, 0%-20%) and highest (most deprived areas: ADI, 80%-100%) ADI quintiles.

Results

A total of 277 patients were included in the final analysis (mean [SD] age, 64.18 [9.60] years; 215 [77.6%] male). Cancer sites were the oral cavity (52 [18.8%]), oropharyngeal area (171 [61.7%]), and larynx or hypopharynx (54 [19.5%]). Multivariable analysis showed that for every 1-point increase in ADI, social-emotional QOL changed by -0.14 points (95% CI, -0.24 to -0.05 points), anxiety increased by 0.03 points (95% CI, 0.01-0.06 points), and neck disability worsened by 0.05 points (95% CI, 0.01-0.10 points). Compared with patients in the most affluent areas, those in the most deprived areas had significantly lower physical (-15.89 points; 95% CI, -25.96 to -2.31 points; Cohen d = -0.83) and social-emotional (-13.57 points; 95% CI, -22.79 to -3.49 points; Cohen d = -0.69) QOL and higher depression (2.60 points; 95% CI, 0.21-4.40 points; Cohen d = 0.52), anxiety (3.12 points; 95% CI, 1.56-4.66 points; Cohen d = 0.61), insomnia (3.55 points; 95% CI, 0.33-6.41 points; Cohen d = 0.54), and neck disability (5.65 points; 95% CI, 1.66-9.55 points; Cohen d = 0.66) scores.

Conclusions and Relevance

In this cross-sectional study, a higher ADI score was associated with higher risk of increased psychological distress, higher symptom burden, and decreased QOL after treatment among HNC survivors. These findings suggest that proactive, patient-centered interventions are needed to address these disparities.

Association of surgeon-patient sex concordance with postoperative outcomes following complex cancer surgery

BACKGROUND AND OBJECTIVES

Sex concordance may impact the therapeutic relationship and provider-patient interactions. We sought to define the association of surgeon-patient sex concordance on postoperative patient outcomes following complex cancer surgery.

METHODS

Patients who underwent surgery for lung, breast, hepato-pancreato-biliary, or colorectal cancer between 2014 and 2020 were identified from the Medicare Standard Analytic Files. The impact of surgeon-patient sex concordance or discordance on achieving an optimal postoperative textbook outcome (TO) was assessed using multivariable logistic regression.

RESULTS

Among 495 628 patients, 241 938 (48.8%) patients were sex concordant with their surgeon while 253 690 (51.2%) patients were sex discordant. Sex discordance between surgeon and patient was associated with a decreased likelihood to achieve a postoperative TO (odds ratio [OR]: 0.95, 95% CI: 0.93-0.97; p < 0.001). Sex discordance was associated with a higher risk of complications (OR: 1.05, 95% CI: 1.03-1.07; p < 0.001) and 90-day mortality (OR: 1.05, 95% CI: 1.01-1.09; p = 0.011). Of note, male patients treated by female surgeons (OR: 0.96, 95% CI: 0.93-0.99; p = 0.017) had a similar lower likelihood to achieve a TO as female patients treated by male surgeons (OR: 0.90, 95% CI: 0.86-0.93; p < 0.001).

CONCLUSIONS

Sex discordance was associated with a reduced likelihood of achieving an "optimal" postoperative course following complex cancer surgery.

Evaluating Social Determinants of Health Related to Cancer Survivorship and Quality of Care

BACKGROUND

Social determinants of health posit that negative outcomes are influenced by individuals living in underserved and underresourced neighborhoods.

OBJECTIVE

This study examines a cancer diagnosis, race/ethnicity, age, geographic location (residence), education, and social economic status factors at disease onset and treatment.

METHODS

A multivariable PO regression analysis was run for quality of care at testing or diagnosis, and quality of care at treatment and the quality of received care compared with another person.

RESULTS

Participants are representative of the Southern Community Cohort Study (SCCS) of adults diagnosed with breast (n = 263), prostate (n = 195), lung (n = 46), colorectal (n = 105), or other cancers (n = 526). This study includes cancer survivors who completed the SCCS Baseline and Cancer Navigation Surveys in urban (73.13%) and rural (26.87%) areas. White participants reported a higher quality of received care for testing or diagnosis and care for treatment compared with Black participants. Participants with high school or equivalent education (odds ratio, 1.662; 95% confidence interval, 1.172-2.356; P = .0044) or some college or junior college education (odds ratio, 1.970; 95% confidence interval, 1.348-2.879; P = .0005) were more likely to report a better level of quality of received care for treatment.

CONCLUSIONS

The SCCS represents individuals who are historically underrepresented in cancer research. The results of this study will have broad implications across diverse communities to reduce disparities and inform models of care.

IMPLICATIONS FOR PRACTICE

Nurses are positioned to evaluate the quality of population health and design and lead interventions that will benefit underserved and underresourced communities.

A Scoping Review of Personalized, Interactive, Web-Based Clinical Decision Tools Available for Breast Cancer Prevention and Screening in the United States

Introduction. Personalized web-based clinical decision tools for breast cancer prevention and screening could address knowledge gaps, enhance patient autonomy in shared decision-making, and promote equitable care. The purpose of this review was to present evidence on the availability, usability, feasibility, acceptability, quality, and uptake of breast cancer prevention and screening tools to support their integration into clinical care. Methods. We used the Preferred Reporting Items for Systematic reviews and Meta-Analyses extension for Scoping Reviews Checklist to conduct this review. We searched 6 databases to identify literature on the development, validation, usability, feasibility, acceptability testing, and uptake of the tools into practice settings. Quality assessment for each tool was conducted using the International Patient Decision Aid Standard instrument, with quality scores ranging from 0 to 63 (lowest-highest). Results. We identified 10 tools for breast cancer prevention and 9 tools for screening. The tools included individual (e.g., age), clinical (e.g., genomic risk factors), and health behavior (e.g., alcohol use) characteristics. Fourteen tools included race/ethnicity, but no tool incorporated contextual factors (e.g., insurance, access) associated with breast cancer. All tools were internally or externally validated. Six tools had undergone usability testing in samples including White (median, 71%; range, 9%-96%), insured (99%; 97%-100%) women, with college education or higher (60%; 27%-100%). All of the tools were developed and tested in academic settings. Seven (37%) tools showed potential evidence of uptake in clinical practice. The tools had an average quality assessment score of 21 (range, 9-39). Conclusions. There is limited evidence on testing and uptake of breast cancer prevention and screening tools in diverse clinical settings. The development, testing, and integration of tools in academic and nonacademic settings could potentially improve uptake and equitable access to these tools.

Highlights

There were 19 personalized, interactive, Web-based decision tools for breast cancer prevention and screening.Breast cancer outcomes were personalized based on individual clinical characteristics (e.g., age, medical history), genomic risk factors (e.g., BRCA1/2), race and ethnicity, and health behaviors (e.g., smoking). The tools did not include contextual factors (e.g., insurance status, access to screening facilities) that could potentially contribute to breast cancer outcomes.Validation, usability, acceptability, and feasibility testing were conducted mostly among White and/or insured patients with some college education (or higher) in academic settings. There was limited evidence on testing and uptake of the tools in nonacademic clinical settings.

Persistent poverty impacts access to minimally invasive surgery among patients with hepatopancreatobiliary cancer

BACKGROUND AND OBJECTIVES

Minimally invasive surgery (MIS) has been successfully adopted in hepatopancreatobiliary (HPB) cancer, and has been associated with improved perioperative and comparable oncological outcomes. We sought to define the impact of county-level duration of poverty on access to MIS and clinical outcomes among patients with HPB cancer undergoing surgical treatment.

MATERIALS AND METHODS

Data on patients diagnosed with HPB cancer were obtained from the Surveillance, Epidemiology, and End Results (SEER)-Medicare data (2010-2016). County-level poverty data were obtained from the American Community Survey and the U.S. Department of Agriculture, and categorized into three groups: never high poverty (NHP), intermittent high poverty (IHP), and persistent poverty (PP). Multivariable regression was used to assess the relationship between PP and MIS.

RESULTS

Among 8098 patients, 82% (n = 664) resided in regions with NHP, 13.6% (n = 1104) resided in regions with IHP, and 4.4% (n = 350) resided in regions with PP. Median age at the diagnosis was 71 years (interquartile range [IQR]: 67-77). Patients from IHP and PP counties had lower odds of undergoing MIS (IHP/PP vs. NHP, odds ratio [OR]: 0.59, 95% confidence interval [CI]: 0.36-0.96, p = 0.034) and being discharged home (IHP/PP vs. NHP, OR: 0.64, 95% CI: 0.43-0.99, p = 0.043), as well as a higher risk of 1-year mortality (IHP/PP vs. NHP, HR: 1.51, 95% CI: 1.036-2.209, p = 0.032) compared with patients residing in NHP counties.

CONCLUSIONS

Duration of county-level poverty was associated with lower receipt of MIS and unfavorable clinical and survival outcomes among patients with HPB cancer. There is a need to improve access to modern surgical treatment options among vulnerable, PP populations.

Development and Testing of a Mobile App to Collect Social Determinants of Health Data in Cancer Settings: Interview Study

BACKGROUND

Social determinants of health (SDOH) such as lack of basic resources, housing, transportation, and social isolation play an important role for patients on the cancer care continuum. Health systems' current technological solutions for identifying and managing patients' SDOH data largely focus on information recorded in the electronic health record by providers, which is often inaccessible to patients to contribute to or modify.

OBJECTIVE

We developed and tested a patient-centric SDOH screening tool designed for use on patients' personal mobile phone that preserves patient privacy and confidentiality, collects information about the unmet social needs of patients with cancer, and communicates them to the provider.

METHODS

We interviewed 22 patients with cancer, oncologists, and social workers associated with a US-based comprehensive cancer center to better understand how patients' SDOH information is collected and reported. After triangulating data obtained from thematic analysis of interviews, an environmental scan, and a literature search of validated tools to collect SDOH data, we developed an SDOH screening tool mobile app and conducted a pilot study of 16 dyadic pairs of patients and cancer care team members at the same cancer center. We collected patient SDOH data using 36 survey items covering 7 SDOH domains and used validated scales and follow-up interviews to assess the app's usability and acceptability among patients and cancer care team members.

RESULTS

Formative interviews with patients and care team members revealed that transportation, financial challenges, food insecurity, and low health literacy were common SDOH challenges and that a mobile app that collected those data, shared those data with care team members, and offered supportive resources could be useful and valuable. In the pilot study, 25% (4/16) of app-using patients reported having at least one of the abovementioned social needs; the most common social need was social isolation (7/16, 44%). Patients rated the mobile app as easy to use, accurately capturing their SDOH, and preserving their privacy but suggested that the app could be more helpful by connecting patients to actual resources. Providers reported high acceptability and usability of the app.

CONCLUSIONS

Use of a brief, patient-centric, mobile app-based SDOH screening tool can effectively capture SDOH of patients with cancer for care team members in a way that preserves patient privacy and that is acceptable and usable for patients and care team members. However, only collecting SDOH information is not sufficient; usefulness can be increased by connecting patients directly to resources to address their unmet social needs.

Sickle cell disease and social determinants of health: A scoping review

Social determinants of health (SDoH) may impact outcomes in sickle cell disease (SCD). We conducted a comprehensive literature review of five electronic databases to elucidate the relationship between SDoH and SCD, and identify gaps in the literature. Our search yielded 59 articles, which we organized into five SDoH areas: Neighborhood and Built Environment, Health and Healthcare, Social and Community Context, Education, and Economic Stability. We found that social determinants, such as access to healthcare, were inconsistently evaluated. Improved recognition and understanding of SDoH should enhance the development of programs that directly address its detrimental effects on patients with SCD.

Disparities in the survival of endometrial cancer patients in a public healthcare system: A population-based cohort study

OBJECTIVE

Social determinants of health (SDH) have been shown to correlate with adverse cancer outcomes. It is unclear if their impact goes beyond behavioral risk or healthcare access. We aimed to evaluate the association of SDH with endometrial cancer outcomes in a public healthcare system.

METHODS

A retrospective cohort study of endometrial cancer patients diagnosed between 2009 and 2017 in Ontario, Canada. Clinical and sociodemographic variables were extracted from administrative databases. Validated multifactorial marginalization scores for domains of material deprivation, residential instability and ethnic concentration were used. Associations between marginalization and survival were evaluated using log-rank testing and Cox proportional hazards regression.

RESULTS

20228 women with endometrial cancer were identified. Fewer patients in marginalized communities presented with early disease (70% vs. 76%, p < 0.001) and received surgery (89% vs. 93%, p < 0.001). Overall survival was shorter among marginalized patients (p < 0.001). On multivariable analysis adjusted for patient and disease factors, overall marginalization (HR = 1.22, 95% CI 1.03-1.08), material deprivation (HR = 1.22, 95% CI 1.10-1.35) and residential instability (HR = 1.32, 95% CI 1.19-1.46) were associated with increased risk of death (p < 0.001).

CONCLUSIONS

Socioeconomic marginalization is associated with an increased risk of death in endometrial cancer patients. Targetable events in the cancer care pathway should be identified to improve health equity.
