Adaptation of Remote Symptom Monitoring Using Electronic Patient-Reported Outcomes for Implementation in Real-World Settings

PURPOSE

Despite evidence of clinical benefits, widespread implementation of remote symptom monitoring has been limited. We describe a process of adapting a remote symptom monitoring intervention developed in a research setting to a real-world clinical setting at two cancer centers.

METHODS

This formative evaluation assessed core components and adaptations to improve acceptability and fit of remote symptom monitoring using Stirman's Framework for Modifications and Adaptations. Implementation outcomes were evaluated in pilot studies at the two cancer centers testing technology (phase I) and workflow (phase II and III) using electronic health data; qualitative evaluation with semistructured interviews of clinical team members; and capture of field notes from clinical teams and administrators regarding barriers and recommended adaptations for future implementation.

RESULTS

Core components of remote symptom monitoring included electronic delivery of surveys with actionable symptoms, patient education on the intervention, a system to monitor survey compliance in real time, the capacity to generate alerts, training nurses to manage alerts, and identification of personnel responsible for managing symptoms. In the pilot studies, while most patients completed > 50% of expected surveys, adaptations were identified to address barriers related to workflow challenges, patient and clinician access to technology, digital health literacy, survey fatigue, alert fatigue, and data visibility.

CONCLUSION

Using an implementation science approach, we facilitated adaptation of remote symptom monitoring interventions from the research setting to clinical practice and identified key areas to promote effective uptake and sustainability.

Distribution of microbiota in cervical preneoplasia of racially disparate populations

BACKGROUNDS

Microbiome dysbiosis is an important contributing factor in tumor development and thus may be a risk predictor for human malignancies. In the United States, women with Hispanic/Latina (HIS) and African American (AA) background have a higher incidence of cervical cancer and poorer outcomes than Caucasian American (CA) women.

METHODS

Here, we assessed the distribution pattern of microbiota in cervical intraepithelial neoplasia (CIN) lesions obtained from HIS (n = 12), AA (n = 12), and CA (n = 12) women, who were screened for CC risk assessment. We employed a 16S rRNA gene sequencing approach adapted from the NIH-Human Microbiome Project to identify the microbial niche in all CIN lesions (n = 36).

RESULTS

We detected an appreciably decreased abundance of beneficial Lactobacillus in the CIN lesions of the AA and HIS women compared to the CA women. Differential abundance of potentially pathogenic Prevotella, Delftia, Gardnerella, and Fastidiosipila was also evident among the various racial groups. An increased abundance of Micrococcus was also evident in AA and HIS women compared to the CA women. The detection level of Rhizobium was higher among the AA ad CA women compared to the HIS women. In addition to the top 10 microbes, a unique niche of 27 microbes was identified exclusively in women with a histopathological diagnosis of CIN. Among these microbes, a group of 8 microbiota; Rubellimicrobium, Podobacter, Brevibacterium, Paracoccus, Atopobium, Brevundimonous, Comamonous, and Novospingobium was detected only in the CIN lesions obtained from AA and CA women.

CONCLUSIONS

Microbial dysbiosis in the cervical epithelium represented by an increased ratio of potentially pathogenic to beneficial microbes may be associated with increased CC risk disparities. Developing a race-specific reliable panel of microbial markers could be beneficial for CC risk assessment, disease prevention, and/or therapeutic guidance.

Identification of target population in the implementation of navigator-delivered home ePRO for patients with cancer receiving treatment

351

Background: One key challenge of practice transformation activities, such as remote symptom monitoring (RSM) using electronic patient reported outcomes (ePROs), is identification of patients starting treatment. In real-world settings, reliance on referrals is likely to miss patients. We describe the difficulties encountered in patient identification and the subsequent changes implemented in protocol to remediate this. Methods: We conducted two PDSA cycles focused on identification and engagement of patients for RSM at the Mitchel Cancer Institute (MCI). Target patient capture was > 75%. Modifications to the patient identification process were documented. Schedules of physicians participating in the RSM program were reviewed from 6/2021 – 5/2022 to identify eligible patients. Patients were considered eligible if they were starting chemotherapy, targeted therapy, or immunotherapy. Patients seeking a second opinion were excluded. Patient demographics, cancer type, cancer stage, and PROs were abstracted from electronic health records and the PRO platform (Carevive). Initial clinic roll-out was conducted in gynecologic oncology, with expansion to breast and thoracic oncology in 10/2021 and 3/2022, respectively. The proportion of eligible patients approached per month was reported.Results: In the first PDSA cycle, the eligibility criteria was defined. Although clinical trials included advanced disease, non-clinical staff screening expressed concern about determining advanced vs. early-stage disease. Thus, inclusion criteria was broadened to include all patients starting treatments. From 6/2021 –8/2021, navigators identified patients by screening patients who presented for chemo-education visits. The navigation team approached 23 patients during this period. However, this process didn’t identify all eligible patients as not all patients beginning treatment received chemo-education visits. In PDSA Cycle 2, the process for new patient contact from initial call for appointment through treatment was reviewed. The implementation team screened all patients in a physician’s schedule a week prior to the office visit as well as on the day of visit. This updated process identified all eligible patients starting either intravenous or oral chemotherapy. The recruitment process was modified to screen the physician schedules rather than chemo educator visits. From 9/2022-5/22, the proportion of eligible patients identified and approached remained high at 100%. This methodological screening process helped the navigation team identify all eligible patients in an efficient manner and they reported comfort in expanding to additional disease teams. Conclusions: Systematic screening of physician schedules can be successfully leveraged for patient identification and reduce time spent manually screening for eligible patients by non-clinical navigators. Clinical trial information: NCT04809740.

Sociodemographic difference in patients who enroll and decline remote symptom monitoring (RSM)

268

Background: Remote symptom monitoring (RSM) using patient-reported outcomes has been shown to reduce symptom burden and hospitalizations in clinical trials. However, little is known about how willing patients are to participate in remote symptom monitoring in real-world settings, particularly for vulnerable patient populations. This study aims to compare characteristics of cancer patients enrolled vs. patients who declined enrollment into RSM. Methods: This prospective study used data that assessed the characteristics of patients who enrolled vs. patients who declined enrollment into RSM. Inclusion criteria included participants’ age ≥18 with cancer who received chemotherapy, targeted therapy, or immunotherapy at the University of Alabama at Birmingham. Race and ethnicity (Black or African American, White, Asian, other and unknown), sex, cancer type (breast, gastrointestinal [GI], genitourinary [GU], gynecological [GYNX], head and neck, leukemia, lymphoma, melanoma, myeloma and other), urban/rural residence, Area Deprivation Index (ADI), and insurance type (Medicaid, Medicare, none, other and private) were abstracted from electronic medical records (EMR) and PRO platform (Carevive). Descriptive statistics were calculated using frequencies and percentages for categorical variables and medians and interquartile ranges for continuous variables. Differences in enrollment status characteristics were calculated using measures of effect size such as Cramer’s V. Results: Of the 307 patients, two thirds of patients were female (71%); 25% were Black or African American and 66% were White patients; 15% lived in an area of higher disadvantage. For insurance, 46%, 26%, 10%, 8%, and 9% of patients had Private, Medicare, Medicaid, other insurance, and no insurance, respectively. The proportion of patients who declined enrollment was higher for males than females (22% vs. 10%), Black or African American than White (18% vs 13%); and having Medicare than private insurance (22% vs. 10%). Compared to those who enrolled, patients who declined enrollment were more often to be male (V:0.2), Black or African American (V:0.1); and have Medicare insurance (V:0.2). Patients enrolled vs. declined in RSM had similar ADI scores (V:0.01). Conclusions: This study demonstrates that potentially vulnerable patients, including Black patients and those with public insurance, have lower RSM engagement. Future analysis is needed to understand participation barriers and how to better engage diverse populations to ensure optimal healthcare delivery to all patients.

Evaluating nurses' time to response by severity and cancer stage in a remote symptom monitoring program

341

Background: Remote symptom monitoring (RSM) using electronic patient reported outcomes (ePROs) allow for patients with cancer to communicate symptoms to their clinical team between clinic visits. Prior randomized control trials of RSM focused on advanced cancer, and less data are available for patient with early stage cancers. The University of Alabama at Birmingham (UAB) implemented RSM for early stage (I-III) and advanced stage (IV) patients on active treatment. This study evaluates nurses’ real-world response time to alerts by varying severity and by patients cancer stages. Methods: This study included women with stage I-IV breast cancer who received care at UAB from October 2020 through May 2022. The program was first implemented in the breast clinic allowing for larger patient numbers with early and advanced stage breast cancer. A composite score for symptom severity is automatically calculated in the Carevive® platform for moderate, severe, or worsening symptoms using patient responses for frequency, severity, and interference. The nurse receives an alert if a symptom is moderate or severe. Surveys with at least one severe alert were categorized as severe and response time was categorized as optimal if the survey was closed within 48 hours (goal time for phone message follow-up). Odds ratios (OR), predicted probabilities, and 95% confidence intervals (CI) were estimated using a patient nested logistic regression evaluating time to response comparing surveys with at least one severe alert notification to those with no severe, adjusting for age at enrollment, race, cancer stage, provider who closed the surveys, and quarter from study start and date. An interaction between severity and cancer stage was evaluated. Results: Of 137 patients included in this study, 64% were White; 86% were diagnosed with early-stage breast cancer. The median age at diagnosis was 54 (27-79). Of 802 surveys included, 38% reported at least one severe symptom and 70% had an optimal response time. Similar results were seen when stratified by early vs. advanced stage with 39% and 38% reporting at least one severe alert and 68% and 71% an optimal response time, respectively. In our adjusted analysis, when compared with surveys that had no severe alerts, surveys with at least one severe alert had similar odds of having an optimal response time (OR, 1.29; 95%CI, 0.88, 1.89). No significant interaction between severity and stage was observed on the odds of optimal response time. Conclusions: Response times to alerts were similar regardless of the severity of the alert and cancer stage, suggesting alert management is incorporated into routine workflows and not prioritized based on disease or alert severity. Additional research is needed to understand factors contributing to non-optimal response times.

Trajectory of symptoms reported in remote symptom monitoring over the course of oncology treatment for gynecologic cancers

270

Background: Patients now have the ability to utilize electronic patient reported outcomes (ePROs) for remote symptom monitoring (RSM). This analysis seeks to better understand trajectory of reported symptoms during treatment for patients with gynecologic cancer participating in RSM. Methods: We approached patients with gynecological cancer initiating treatment at the Mitchell Cancer Institute (MCI) between 7/1/21-4/30/2022. Patients were eligible if they were starting chemotherapy, targeted therapy, or immunotherapy for a new cancer. Patients seeking a second opinion were excluded. Enrolled patients received symptom survey (PRO-CTCAE questions) via text or email once per week. Initially, only severe alerts were forwarded to the clinical care team; moderate alerts were forwarded to clinical teams once they were comfortable with alert management. Patients completed symptom assessments for 24 weeks or until withdrawal. Patient age at enrollment, race, sex, cancer type, cancer stage, and PROs were abstracted from electronic health records and the PRO platform (Carevive). Descriptive statistics were calculated using frequencies and percentages for categorical variables and median and interquartile ranges (IQR) for continuous variables. Results: A total of 60 female patients with gynecological cancer were enrolled; 33% were Black or African American and 67% were White; median age was 61 years (IQR 53-68). Seventy-eight percent (47/60) of patients reported 379 symptoms with at least one moderate or severe alert during this time period; 32% considered moderate and 68% considered severe. Overall, the most frequently reported symptom was pain (29%). At baseline (week 0), 14% and 41% of 56 patients reported moderate symptoms and severe symptoms, respectively. Symptom burden decreased over time with 4% and 7% of 27 patients who completed a survey at 12 weeks reporting moderate and severe symptoms. Specific symptom trajectories followed similar patterns. Conclusions: In our sample, patients reported the majority of symptoms during the first three months of treatment. Symptom trajectory decreased with time, suggesting symptoms are being effectively monitored and addressed by the clinical teams engaging in RSM. Future research is needed to understand if symptom improvement translates to increased quality of life, decreased hospitalizations, and increased survival for patients, as well as lessen the burden of call volume on the clinical team.

Adaptation of remote symptom monitoring using electronic patient-reported outcomes for implementation in real-world settings

Background: Despite evidence of clinical benefits, widespread implementation of remote symptom monitoring has been limited. We describe a process of adapting a remote symptom monitoring intervention developed in a research setting to a real-world clinical setting at two cancer centers.

Nursing strategies to improve alert closure for remote symptom monitoring

421

Background: For successful remote symptom monitoring using patient-reported outcomes, nurses should respond to alerts in a timely fashion. Where clinical trials utilized research staff for alert management, the shift to standard-of-care delivery necessitates that this responsibility be added as a task to an already strained nursing workforce. Little is known about strategies to engage nurses to improve timeliness of alert management. Methods: In this quality improvement initiative, we aimed to improve timeliness of alert closures generated by moderate or severe symptoms within a remote symptom monitoring program. Optimal closure was defined as < 48 hours, which was consistent with institutional requirements for response to patient phone calls. A continuous quality improvement approach, with multiple Plan Do Study Act (PDSA) cycles was conducted. Data was captured from the electronic medical record and PRO platform (Carevive). Descriptive statistics included frequencies and percentages. The proportion of alerts closed each month < 48 hours, 48-72 hours, 3-7 days, and > 7 days were reported overall and by disease team (i.e., major cancer types). Surveys not closed were considered > 7 days. The timing of strategies to improve nursing engagement were documented and evaluated for impact on alert closure. Results: From June 1, 2021-May 31, 2022, 1121 moderate or severe alerts were generated from 234 patients. Disease teams had variable remote symptom monitoring start dates: breast, leukemia, and limited gynecologic (prior to 6/2021); myeloma and gastrointestinal (7/2021); genitourinary (10/2021); head and neck (12/2021); melanoma (2/2022); and Lymphoma (4/2022). In 6/2021, the overall alert closure at < 48 hours, 48-72 hours, 3-7 days, and > 7 days was 57%, 4%, 14%, and 25% respectively (n = 28). To improve alert closures, several key strategies were deployed to improve alert closure times including disease-specific reporting and meetings with nursing leadership (10/2021); identification of a nurse champion, creation of “cheat sheets” to remind nurses how to close alerts, and individualized calls with nurses with open alerts (1/2022), and inclusions of requirement to close alerts in nursing newsletters (2/2022). Overall, alert closure less than 48 hours improved to 61% by 12/2021 (n = 97) and to 69% by 5/2022 (n = 167). Disease group alert closure varied, with higher closure more commonly in teams with greater duration of use, such as breast cancer team with an alert closure of 85% < 48 hours in May 2022. Conclusions: Key nursing engagement strategies improve alert closure for remote symptom monitoring programs implemented in real-world settings.

The Project ENABLE Cornerstone randomized controlled trial: study protocol for a lay navigator-led, early palliative care coaching intervention for African American and rural-dwelling advanced cancer family caregivers

Background

Family caregivers play a vital, yet stressful role in managing the healthcare needs and optimizing the quality of life of patients with advanced cancer, from the time they are newly diagnosed until end of life. While early telehealth palliative care has been found to effectively support family caregivers, little work has focused on historically under-resourced populations, particularly African American and rural-dwelling individuals. To address this need, we developed and are currently testing Project ENABLE (Educate, Nurture, Advise, Before Life Ends) Cornerstone, a lay navigator-led, early palliative care coaching intervention for family caregivers of African American and rural-dwelling patients with newly diagnosed advanced cancer.

Methods

This is a 2-site, single-blind, hybrid type I implementation-effectiveness trial of the Cornerstone intervention versus usual care. Cornerstone is a multicomponent intervention based on Pearlin’s Stress-Health Process Model where African American and/or rural-dwelling family caregivers of patients with newly diagnosed advanced cancer (target sample size = 294 dyads) are paired with a lay navigator coach and receive a series of six, brief 20–60-min telehealth sessions focused on stress management and coping, caregiving skills, getting help, self-care, and preparing for the future/advance care planning. Subsequent to core sessions, caregivers receive monthly follow-up indefinitely until the patient’s death. Caregiver and patient outcomes are collected at baseline and every 12 weeks until the patient’s death (primary outcome: caregiver distress at 24 weeks; secondary outcomes: caregiver: quality of life and burden; patient: distress, quality of life, and healthcare utilization). Implementation costs and the intervention cost effectiveness are also being evaluated.

Discussion

Should this intervention demonstrate efficacy, it would yield an implementation-ready model of early palliative care support for under-resourced family caregivers. A key design principle that has centrally informed the Cornerstone intervention is that every caregiving situation is unique and each caregiver faces distinct challenges that cannot be addressed using a one-size-fits all approach. Hence, Cornerstone employs culturally savvy lay navigator coaches who are trained to establish a strong, therapeutic alliance with participants and tailor their coaching to a diverse range of individual circumstances.

Evaluating the implementation and impact of navigator-supported remote symptom monitoring and management: a protocol for a hybrid type 2 clinical trial

Background

Symptoms in patients with advanced cancer are often inadequately captured during encounters with the healthcare team. Emerging evidence demonstrates that weekly electronic home-based patient-reported symptom monitoring with automated alerts to clinicians reduces healthcare utilization, improves health-related quality of life, and lengthens survival. However, oncology practices have lagged in adopting remote symptom monitoring into routine practice, where specific patient populations may have unique barriers. One approach to overcoming barriers is utilizing resources from value-based payment models, such as patient navigators who are ideally positioned to assume a leadership role in remote symptom monitoring implementation. This implementation approach has not been tested in standard of care, and thus optimal implementation strategies are needed for large-scale roll-out.

Methods

This hybrid type 2 study design evaluates the implementation and effectiveness of remote symptom monitoring for all patients and for diverse populations in two Southern academic medical centers from 2021 to 2026. This study will utilize a pragmatic approach, evaluating real-world data collected during routine care for quantitative implementation and patient outcomes. The Consolidated Framework for Implementation Research (CFIR) will be used to conduct a qualitative evaluation at key time points to assess barriers and facilitators, implementation strategies, fidelity to implementation strategies, and perceived utility of these strategies. We will use a mixed-methods approach for data interpretation to finalize a formal implementation blueprint.

Discussion

This pragmatic evaluation of real-world implementation of remote symptom monitoring will generate a blueprint for future efforts to scale interventions across health systems with diverse patient populations within value-based healthcare models.

HPV Vaccination Champions: Evaluating a Technology-Mediated Intervention for Parents

Human papillomavirus (HPV) vaccination prevents 6 HPV-related cancers in men and women. Yet, rates of HPV vaccination among adolescents in the United States lag behind other developed nations, revealing a significant public health issue. This feasibility study tested a collaborative online learning environment to cultivate HPV vaccination champions. A 3-month training program recruited parents to serve as proponents and social media influencers to identify solutions to overcome barriers to HPV vaccination. A mixed methods study design included a pretest survey, three online asynchronous focus groups, a posttest survey, as well as a longitudinal follow-up survey at 6 months. Participants included 22 parents who self-identified as female (95.4%) and white (90.9%). Overall, there was a statistically significant difference in knowledge of HPV and HPV vaccination between pretest and posttest (p = 0.0042). This technology-mediated intervention increased parents' confidence and motivated them to speak more freely about HPV vaccination in-person and online with others in their social networks. Participants identified prevalent misinformation about HPV vaccination and learned how to effectively craft messages to address concerns related to safety and side effects, gender, understanding of risk, and sexual activity. Objective measures and qualitative open-ended assessment showed high intervention engagement and treatment satisfaction. All participants (100%) indicated that they enjoyed participating in the intervention. The effectiveness of this feasibility study suggests that social media is an appropriate platform to empower parents to counter vaccine hesitancy and misinformation through HPV vaccination information that is simple and shareable in-person and online.

Correcting HPV Vaccination Misinformation Online: Evaluating the HPV Vaccination NOW Social Media Campaign

The human papillomavirus (HPV) vaccine provides protection from six HPV-related cancers. Approximately half of South Carolina adolescents have not completed the vaccination series, representing a missed opportunity to prevent cancer. The HPV Vaccination NOW: This is Our Moment social media campaign is an initiative of the South Carolina Cancer Alliance (SCCA) and Hollings Cancer Center at the Medical University of South Carolina (MUSC). This statewide social media campaign aimed to increase parental awareness of and build vaccine confidence around HPV vaccination in S.C. The ten-week campaign was strategically implemented between June and August 2019 to encourage HPV vaccination at back-to-school medical appointments. A process evaluation showed that the campaign resulted in over 370,000 total impressions, reached over 33,000 individuals, and culminated with over 1122 followers. There were over 2700 engagements on Facebook and Twitter. A qualitative content analysis indicated that pro-vaccine and anti-vaccine comments were dominated by personal stories. Comments promoting misinformation about the HPV vaccine were often countered through peer-to-peer dialogue. Findings suggest that creating opportunities for the target audience to engage with campaign messages effectively corrected misinformation.

Factors associated with HPV vaccination initiation among United States college students

Human papillomavirus (HPV) remains the most common sexually transmitted infection (STI) in the U.S. despite widespread availability of a safe, effective vaccine. Although young adults are at greatest risk of HPV infection, extensive vaccine promotion and intervention efforts has been directed toward 11-12-year-olds. College students represent an ideal audience for HPV vaccine "catch-up;" however, research indicates inconsistent HPV vaccination rates within this demographic. An online survey assessing HPV and HPV vaccine knowledge and behaviors was distributed to all undergraduate college students at a large, public university in the Deep South region of the U.S. The primary outcome was receipt of HPV vaccination (binary response options of Yes/No). Logistic regression analyses were performed to determine predictors of HPV vaccination. Of the 1,725 who completed the survey, 47.0% reported having received at least one dose of HPV vaccine; overall series completion (series = 3 doses for this population) was 17.4%. The primary outcome was HPV initiation among college students, defined as having received at least one dose of the HPV vaccine. Results indicated substantial gaps in participants' knowledge of their vaccination status. Provider and parental recommendations as well as social influences were shown to significantly impact student vaccination status, emphasizing the importance of incorporating these elements in future interventions, potentially as multi-level strategies. Future college interventions should address HPV and vaccination knowledge and the importance of provider and parental recommendations.

Health care-related time costs in patients with metastatic breast cancer

BACKGROUND

Burdens related to time spent receiving cancer care may be substantial for patients with incurable, life-limiting cancers such as metastatic breast cancer (MBC). Estimates of time spent on health care are needed to inform treatment-related decision-making.

METHODS

Estimates of time spent receiving cancer-related health care in the initial 3 months of treatment for patients with MBC were calculated using the following data sources: (a) direct observations from a time-in-motion quality improvement evaluation (process mapping); (b) cross-sectional patient surveys; and (c) administrative claims. Average ambulatory, inpatient, and total health care time were calculated for specific treatments which differed by antineoplastic type and administration method, including fulvestrant (injection, hormonal), letrozole (oral, hormonal), capecitabine (oral, chemotherapy), and paclitaxel (infusion, chemotherapy).

RESULTS

Average total time spent on health care ranged from 7% to 10% of all days included within the initial 3 months of treatment, depending on treatment. The greatest time contributions were time spent traveling for care and on inpatient services. Time with providers contributed modestly to total care time. Patients receiving infusion/injection treatments, compared with those receiving oral therapy, spent more time in ambulatory care. Health care time was higher for patients receiving chemotherapeutic agents compared to those receiving hormonal agents.

CONCLUSION

Time spent traveling and receiving inpatient care represented a substantial burden to patients with MBC, with variation in time by treatment type and administration method.

Minority participation in phase 1 gynecologic oncology clinical trials: Three decades of inequity

OBJECTIVES

It is important to develop effective therapies in minorities to ensure equity in cancer care. Underrepresentation of minorities in early phase trials may cause therapies that are effective only in majority populations. We evaluated minority participation in gynecologic oncology phase 1 clinical trials.

METHODS

In peer-reviewed published articles of gynecologic oncology phase 1 clinical trials from years 1985 to 2018, we manually abstracted racial distribution of enrolled participants, cancer type, and year published. We calculated expected and observed ratios of racial participation on the basis of age-adjusted cancer incidence for race from the United States Centers for Disease Control and Prevention.

RESULTS

We identified 357 articles of phase 1 trials (total, 9492 participants), including 213 articles on ovarian cancer (60%). Racial distribution of participants was available in 84 articles (23%) that included 2483 participants (26%): 1950 white (79%), 140 black (5%), and 393 other participants (16%). Other nonwhite races exceeded black enrollment in 46 of 84 trials (55%) that listed race. Enrollment of black participants was less than expected from disease incidence for ovarian (incidence-to-enrollment ratio, 18.5; P < .001), endometrial (3.6; P < .001), and cervical cancer (6.8; P < .001). No phase 1 study met expected enrollment for black participants. Frequency of black participants decreased 1.8-fold from 1995 to 1999 (8 of 70 participants [11%]) to 2015-2018 (55 of 892 participants [6%]; P < .025).

CONCLUSIONS

Major racial underrepresentation exists in gynecologic oncology phase 1 clinical trials. Enrollment of more black participants is needed to achieve racial equity.

Oncology practice changes during a multistep Oncology Care Model practice transformation project

88

Background: Treatment of lung cancer has seen a paradigm shift in recent years. While the availability of newer treatment options such as targeted therapy and immunotherapy have provided new hope for better outcomes, this has added to the cost of care. Participation in the Center for Medicare Services’ Oncology Care Model (OCM) provides opportunities for oncology practices to identify practice transformation (PT) change strategies that result in improved quality of care (QOL) and cost savings. Methods: A lung cancer PT team convened to facilitate changes that improve patient outcomes and decrease costs at an OCM organization. The year-long project included clinical treatment updates, quantitative and qualitative assessments, and data sharing. Practice changes focused on biomarker driven treatment selection, nurse navigation to better manage symptoms and decrease emergency department (ED) visits and hospitalizations, and earlier advanced care planning (ACP) discussions. Surveys were completed by oncology physicians and nurse practitioners at baseline (n = 9) and end of the project (n = 7). Results: After education, there were more correct responses in 3 of 6 knowledge questions and providers noted less concern about performance status or co-morbidities when prescribing immunotherapy. Providers noted fewer barriers with biomarker documentation; self-reported confidence in 4 questions of biomarker selection was unchanged. Providers reported increased participation of nurse navigators to impact ED visits and hospitalizations over time. Documentation of ACP discussions increased, 42% (8/19) to 56% (13/23), but did not reach statistical significance due to sample size. Although providers reported changes toward earlier ACP discussions, 1 in 3 still wait until performance status declines to initiate discussion. Conclusions: Systematic PT can improve quality of patients care and measures used in value-based care reimbursement models. Providers need ongoing education, practice feedback, and organizational support to effect positive practice changes. In addition, new strategies to increase provider ability to initiate end of life discussions need to be explored.

Treatment decision-making and financial toxicity in metastatic breast cancer

97

Background: Shared decision-making (SDM), a process where patients partner with their physician to incorporate personal preferences into treatment decisions, is a tenet of high-value healthcare. It is unknown if high-value care associated with SDM manifests in the form of decreased out-of-pocket costs. Therefore, this study analyzes the relationship between patient preference for SDM and financial toxicity in metastatic breast cancer (MBC). Methods: This cross-sectional study utilized surveys of women age ≥ 18 with MBC who received care at two academic hospitals in Alabama between 2017 and 2019. SDM preference and financial toxicity were measured using the Control Preferences Scale and the Comprehensive Score for Financial Toxicity (COST) tool (11-item scale from 0-44, with lower scores indicating worse FT), respectively. Patient demographic and clinical data were abstracted from the electronic medical record. Effect sizes were calculated using Cohen’s d or Cramer’s V. Differences in financial toxicity by SDM preference were estimated using mixed models clustered by site and treating medical oncologist. Results: In 79 women with MBC, 41% preferred SDM, 33% preferred provider-driven decision making, and 22% preferred patient-driven decision making. Patients preferring SDM were more often college educated (48% vs. 40%; V = .15), higher income (52% vs. 44%; V = .09), and privately insured (47% vs. 41%; V = .11). Overall median COST score was 23 (interquartile range 16-30), which varied modestly by SDM preference. After adjusting for patient demographic and clinical characteristics, similar financial toxicity levels were found in patients who preferred SDM (COST 22, 95% confidence interval [CI] 19-25), patient-driven decision making (COST 22, 95% CI 18-26), and provider-driven decision making (COST 24, 95% CI 20-27). Conclusions: Similar levels of financial toxicity were found in patients with differing decision–making preferences regarding their MBC treatment, which may be secondary to lack of discussions about cost. Further research is needed to determine if and how financial toxicity is being identified or included within decision-making.

Health insurance literacy, status, and financial toxicity in women receiving treatment for metastatic breast cancer

96

Background: Though uninsurance rates declined after the Affordable Care Act, the number of underinsured, or individuals who spend > 10% of their income on out-of-pocket (OOP) medical costs, continues to rise. In patients with metastatic breast cancer (MBC), underinsurance may lead to financial toxicity (FT), or patient-level financial burden and distress, since diagnosis and treatment is extremely costly. This study explores health insurance literacy and the association between FT and health insurance status in women receiving treatment for MBC. Methods: This cross-sectional study utilized survey data collected from 2017-2019 in women age ≥18 receiving treatment for MBC at two academic medical centers in Alabama. FT was measured by the Comprehensive Score for Financial Toxicity (COST) tool (11-item scale from 0-44, with lower scores indicating worse FT). Health insurance status and OOP costs were self-reported. Effect sizes were calculated using Cohen’s d or Cramer’s V. Mixed and generalized linear models clustered by site and treating medical oncologist estimated the association between FT and health insurance status. Results: In 81 women with MBC, median COST score was 24 (interquartile range [IQR] 17-30), 44% had private insurance, 40% Medicare, and 16% Medicaid. Though 25% and 33% of surveyed patients did not know their health insurance premium or deductible cost, respectively, privately insured patients more often knew the cost of their premiums (97%; V = 0.58) and deductibles (81%; V = 0.33) compared to publicly insured patients. In adjusted models, FT levels did not differ significantly based on health insurance type (private insurance COST 21, 95% confidence interval [CI] 18-25; Medicaid COST 23, 95% CI 17-29; Medicare COST 24, 95% CI 20-27). However, risk of severe FT (COST ≤13) was 147% higher for privately insured patients versus Medicare beneficiaries (risk ratio 2.47, 95% CI 1.44-4.21). Conclusions: Despite higher levels of health insurance literacy, privately insured patients receiving treatment for MBC may be at increased risk of severe FT. Further research is needed to understand causes of underinsurance in patients with MBC, which could lead to cancer-related FT.

A practice transformation model to improve lung cancer care

92

Background: Lung cancer has the highest cause of cancer death, treatment of which is both complicated and expensive. Emerging actionable biomarkers and treatments provide both opportunity and treatment challenges. Adherence to evidence-based treatment and advanced care discussions add value to care. Oncology practices need to document the above to participate in value-based care reimbursement models. A Practice Transformation (PT) model was implemented to address quality and cost issues. Methods: After IRB approval, baseline data on lung cancer patients diagnosed during a 6-month period (Jul-Dec 2017) were collected through chart abstraction and treatment planning surveys. Rates of molecular testing ordered, results available at time of treatment decision-making, guideline concordant treatment decisions, and documentation of advanced care discussions were presented to the PT team. After education on recent clinical trial results and NCCN treatment guidelines, the PT team determined strategies for change. The PT team met after two 3-month periods of PT for education updates and progress reports. Data was compared on newly diagnosed patients during a 6-month period (Jul-Dec 2018), one year after the baseline period. Results: A total of forty-two patients were diagnosed in two 6-month periods, baseline and study period. Average age was 65 years, 57% male, 71% Caucasian, 95% ever smokers, 71% adenocarcinoma histology. Rate of ordering any molecular testing was (16/19) 84% in the baseline period vs (20/23) 86% in the study period. However, extended molecular testing increased from 16% (3/19) to 60% (12/20), p = .05 Fishers exact test. At treatment initiation, evidence-based treatment selections went from 47% to 52%. Documentation of advanced care discussions, 42% (8/19) to 56% (13/23), did not change significantly. Conclusions: A PT model that included education, and two cycles of implementation and feedback, resulted in increased molecular testing to inform evidence-based treatment selections. Increased awareness of the lack of documentation of advanced care discussions provides opportunity for continued improvement to effect quality care.

A reproductive justice approach to understanding women's experiences with HPV and cervical cancer prevention

Cervical cancer is a preventable disease. HPV infection has been linked to more than 90% of cervical cancers. A vaccine to prevent the acquisition of HPV has been available since 2006. The purpose of this study was to investigate women's perceptions of cervical cancer prevention, including HPV vaccination. A reproductive justice framework guided data collection and analysis. In 2016, researchers conducted 70 in-depth, semi-structured qualitative interviews with women aged 19-78 years in South Carolina. A purposive sampling approach was employed to maximize requisite variety based on social, economic, and environmental axes of inequality. Participants self-identified as white (53%), African American (33%), and Hispanic (9%). Data analysis included an inductive constant comparative method to identify patterns and themes across the interviews. Misinformation about the prevalence and risk of HPV and cervical cancer led to "othering" of women with HPV-related diagnoses based on the flawed assumption of not being at risk. Participants described a lack of knowledge about the effectiveness and safety of the HPV vaccine. Social norms influenced participants' perceptions of HPV vaccination and cervical cancer, including concerns about sexual activity and intergenerational communication. Participants' social construction of identity, including race/ethnicity, socioeconomic position, ability, age, gender, sexual orientation, and immigration status, impacted their perceptions of cervical cancer screening and the HPV vaccine. In particular, participants believed that the HPV vaccine was "only for girls" and identified gender norms that limited uptake. Participants described barriers to accessing health care and cervical cancer screening, including cost, health insurance, and life changes (e.g., pregnancy, relocating). Many participants experienced an abnormal Papanicolaou test and described follow-up care, including biopsies and treatment for cervical dysplasia. Findings from this study offer insight into women's identity and perceptions of cervical cancer prevention. Results provide practical recommendations to increase women's agency in the development of successful public health interventions.

Why do we continue to overtreat stage Ia carcinoma of the cervix?

The current recommended treatment for stage Ia2 cervical cancer is a radical or modified radical hysterectomy. Although in the United States the incidence of cervical cancer is low and declining, almost 50% of the >4000 new cases will present in early stages. An estimated 2200 women each year will undergo radical hysterectomy and many will have both early- and late-onset complications. The purpose of this review is to examine if there is still a role for radical hysterectomy in the proper treatment of stage Ia2 cervical cancer given most recent data. Sufficient histological evidence suggests that although parametrial involvement and lymph node metastases can increase the risk for recurrence, they are relatively uncommon at early stages. Worldwide data that challenge radical hysterectomy as standard of care have shown that conservative management of stage Ia2 cervical cancer results in similar survival and recurrence rates. It is the recommendation based on all reviewed data that radical hysterectomy should no longer be considered standard of care in all cases of stage Ia2 cervical cancer.

Rates of human papillomavirus vaccine uptake amongst girls five years after introduction of statewide mandate in Virginia

BACKGROUND

The Commonwealth of Virginia enacted statewide school-entry human papillomavirus vaccine mandate in 2008 requiring all girls to receive the vaccine before starting the 6th grade. The mandate, one of very few in the country, has been in effect for 5 years. This study assesses the impact that it has had on the rates of human papillomavirus uptake.

OBJECTIVE

The purpose of this study was to evaluate the uptake of the human papillomavirus vaccine among girls seeking well-child care 5 years after the introduction of a statewide mandate in Virginia in October 2008.

STUDY DESIGN

This prospective cohort study used the Clinical Data Repository at the University of Virginia to identify girls 11-12 years old who was seen for well-child care from January to December 2014. Billing and diagnosis codes were used to establish human papillomavirus vaccine administration. Those girls who were identified through the Clinical Data Repository were then contacted by advance letter followed by a representative from the University of Virginia Center for Survey Research who invited the responsible parent or guardian to complete a 50-item telephone questionnaire. Questionnaire results were used to inform objective findings and to assess parental attitudes that were related to human papillomavirus vaccination. Findings were compared against those of Pierce et al (2013), who evaluated human papillomavirus vaccination levels in a similar cohort of patients in 2008, before mandate enactment, to assess relative change attributable to vaccine mandate.

RESULTS

Nine hundred eight girls were identified through the Clinical Data Repository; 50.9% of the girls received at least 1 dose of human papillomavirus vaccine. White race and private insurance coverage were found to be associated negatively with human papillomavirus vaccine uptake (relative risk, 0.74 and 0.71; 95% confidence interval, 0.64-0.85 and 0.62-0.81, respectively). Black race and public insurance coverage were found to be associated positively with vaccine uptake (relative risk, 1.35 and 1.39; 95% confidence interval, 1.17-1.55 and 1.22-1.58, respectively). In comparison with the previous study, there has been no change in human papillomavirus vaccine uptake or distribution of uptake after the introduction of the statewide mandate for human papillomavirus vaccination.

CONCLUSION

The statewide human papillomavirus vaccine mandate has had no impact on the overall rate of human papillomavirus vaccination, nor has it diminished the previously described racial or payer disparities in vaccine uptake in school-aged girls being seen for well-child care in the state of Virginia.

Morbidity and mortality of vulvar and vaginal cancers: Impact of 2-, 4-, and 9-valent HPV vaccines

Vaginal and vulvar cancers do not account for a large proportion of gynecologic malignancies but their impact is significant. Both vaginal and vulvar lesions have precursors and display levels of dysplasia before progression to invasive disease. Human Papillomavirus (HPV) is a known causative agent of such dysplasia and can be detected now more readily than ever with adequate recognition techniques and provider awareness. Although HPV vaccination is still lagging compared to other recommended childhood vaccinations, the impact on lower genital tract neoplasia is promising. The bivalent and quadrivalent vaccines have been shown to be efficacious and the newest nonavalent vaccine should add even more of impact on coverage of cancer-causing HPV types. Although it is still early to show true clinical and population-based disease reduction due to low disease incidence and relatively short time of vaccine availability, the potential is noteworthy.

Increasing HPV vaccination through policy for public health benefit

Vaccines against specific types of human papillomavirus (HPV) linked to cancer and other diseases have been met with mixed acceptance globally and in the United States. Policy-level interventions have been shown to be effective in increasing public health benefit. Government policies and mandates may result in improved HPV vaccination coverage and reduced disease burden, and alternative policies that improve unhindered access to HPV vaccination may allow success as well. The purpose of this commentary is to summarize policy efforts to maximize the public health benefit of HPV vaccination. We examine selected examples of HPV vaccination policy in global contexts and in the United States.

An association between Trichomonas vaginalis and high-risk human papillomavirus in rural Tanzanian women undergoing cervical cancer screening

OBJECTIVE

The goal of this study was to determine the prevalence of vaginitis and its association with high-risk human papillomavirus (HR HPV) in women undergoing cervical cancer screening in rural Tanzania.

METHODS

For the purpose of cervical cancer screening, cytology and HR HPV polymerase chain reaction data were collected from 324 women aged between 30 and 60 years. Microscopy and gram stains were used to detect yeast and bacterial vaginosis. Cervical nucleic acid amplification test specimens were collected for the detection of Trichomonas vaginalis (TV), Chlamydia trachomatis, and Neisseria gonorrhoeae.

RESULTS

The majority of women were married (320 of 324) and reported having a single sexual partner (270 of 324); the median age of participants was 41 years. HR HPV was detected in 42 participants. Forty-seven percent of women had vaginitis. Bacterial vaginosis was the most common infection (32.4%), followed by TV (10.4%), and yeast (6.8%). In multivariable logistic regression analysis, TV was associated with an increased risk of HR HPV (odds ratio, 4.2 [95% CI, 1.7-10.3]). Patients with TV were 6.5 times more likely to have HPV type 16 than patients negative for TV (50% vs 13.3%) (odds ratio, 6.5 [95% CI, 1.1-37]).

CONCLUSIONS

Among rural Tanzanian women who presented for cervical cancer screening, Trichomonas vaginitis was significantly associated with HR HPV infection (specifically type 16).

Transcriptional suppression, DNA methylation, and histone deacetylation of the regulator of G-protein signaling 10 (RGS10) gene in ovarian cancer cells

RGS10 regulates ovarian cancer cell growth and survival, and RGS10 expression is suppressed in cell models of ovarian cancer chemoresistance. However, the mechanisms governing RGS10 expression in ovarian cancer are poorly understood. Here we report RGS10 suppression in primary ovarian cancer and CAOV-3 ovarian cancer cells compared to immortalized ovarian surface epithelial (IOSE) cells, and in A2780-AD chemoresistant cells compared to parental A2780 cells. RGS10-1 and RGS10-2 transcripts are expressed in ovarian cancer cells, but only RGS10-1 is suppressed in A2780-AD and CAOV-3 cells, and the RGS10-1 promoter is uniquely enriched in CpG dinucleotides. Pharmacological inhibition of DNA methyl-transferases (DNMTs) increased RGS10 expression, suggesting potential regulation by DNA methylation. Bisulfite sequencing analysis identified a region of the RGS10-1 promoter with significantly enhanced DNA methylation in chemoresistant A2780-AD cells relative to parental A2780 cells. DNA methylation in CAOV-3 and IOSE cells was similar to A2780 cells. More marked differences were observed in histone acetylation of the RGS10-1 promoter. Acetylated histone H3 associated with the RGS10-1 promoter was significantly lower in A2780-AD cells compared to parental cells, with a corresponding increase in histone deacetylase (HDAC) enzyme association. Similarly, acetylated histone levels at the RGS10-1 promoter were markedly lower in CAOV-3 cells compared to IOSE cells, and HDAC1 binding was doubled in CAOV-3 cells. Finally, we show that pharmacological inhibition of DNMT or HDAC enzymes in chemoresistant A2780-AD cells increases RGS10 expression and enhances cisplatin toxicity. These data suggest that histone de-acetylation and DNA methylation correlate with RGS10 suppression and chemoresistance in ovarian cancer. Markers for loss of RGS10 expression may identify cancer cells with unique response to therapeutics.
