Team-based learning in the internal medicine clerkship didactics

BACKGROUND

Active-learning approaches, such as team-based learning, are infrequently used in internal medicine clerkship didactics even though there is increasing evidence to suggest medical students prefer it over traditional lecture-based learning. In this study, five team-based learning sessions were incorporated into three blocks of a 12-week internal medicine clerkship.

METHODS

The goal of this quasi-experimental study was to compare learner engagement, satisfaction and preference between team-based learning and lecture-based learning in the internal medicine clerkship didactics. Outcomes were compared using the Classroom Engagement Survey, a satisfaction questionnaire and the Team-Based Learning Student Assessment Instrument (TBL-SAI).

FINDINGS

There was a statistically significant difference in the classroom engagement scores between team- and lecture-based learning (P < 0.0001) with a median of 39.0 and 33.0 in the team-based learning and lecture-based learning groups. For learning preference, the median TBL-SAI score was substantially above neutral. Across all team-based learning sessions, 100% of students were satisfied or strongly satisfied with the learning style as a valuable experience and as a way to learn course material, and only one student was not satisfied or strongly satisfied with team-based learning to improve problem solving skills.

DISCUSSION

The classroom engagement and learning style preference findings were consistent with previously published data in other clerkship settings. Student satisfaction was more consistent with team-based learning than with the lecture-based learning, which may be because of the consistent format whereas lecture-based learning style was faculty dependent.

CONCLUSION

Students preferred team-based learning and had improved engagement and satisfaction when compared to lecture-based learning. This study provides evidence in favour of team-based learning as a strategy to incorporate active learning in clerkship didactics.

Evaluation of oncology infusion pharmacy practices: A nationwide survey

PURPOSE

Oncology care continues to evolve at a rapid pace including provision of infusion-based care. There is currently a lack of robust metrics around oncology infusion centers and pharmacy practice. The workgroup completed a nationwide survey to learn about oncology-based infusion pharmacy services offered. The objective was to highlight consistent, measureable oncology-based infusion pharmacy metrics that will provide a foundation to describe overall productivity including emphasis on high patient-safety standards.

METHODS

A nationwide survey was developed via a workgroup within the Vizient Pharmacy Cancer Care Group beginning in April 2019 and conducted electronically via the Vizient Pharmacy Network from September to November 2020. The survey was designed to capture a number of key metrics related to oncology-based infusion pharmacy services.

RESULTS

Forty-one sites responded to the survey. Responses highlighted hours of operation (median = 11.5), number of infusion chairs (median = 45). Staffing metrics included 7.1 pharmacist full-time equivalent (FTE) and 7.6 technician FTE per week. 80.5% of sites had cleanrooms and 95.1% reported both hazardous and nonhazardous compounding hoods. 68.3% of sites reported using intravenous (IV) technology, 50.0% measured turnaround time, and 31.4% prepared treatment medications in advance.

CONCLUSION

There was variability among oncology infusion pharmacy practices in regard to survey responses among sites. The survey results highlight the need for standardization of established productivity metrics across oncology infusion pharmacies in order to improve efficiency and contain costs in the changing oncology landscape. The survey provides insight into oncology infusion pharmacy practices nationwide and provides information for pharmacy leaders to help guide their practices.

The Relationship Between a Lifetime History of Sexual Victimization and Perinatal Depression: A Systematic Review and Meta-Analysis

BACKGROUND

The association between a lifetime history of sexual victimization and the well-being of women during the perinatal period has received increasing attention. However, research investigating this relationship has yet to be systematically reviewed or quantitatively synthesized.

AIM

This systematic review and meta-analysis aims to calculate the pooled effect size estimate of the statistical association between a lifetime history of sexual victimization and perinatal depression (PND).

METHOD

Four bibliographic databases were systematically searched, and reference harvesting was conducted to identify peer-reviewed articles that empirically examined associations between a lifetime history of sexual victimization and PND. A random effects model was used to ascertain an overall pooled effect size estimate in the form of an odds ratio and corresponding 95% confidence intervals (CIs). Subgroup analyses were also conducted to assess whether particular study features and sample characteristic (e.g., race and ethnicity) influenced the magnitude of effect size estimates.

RESULTS

This review included 36 studies, with 45 effect size estimates available for meta-analysis. Women with a lifetime history of sexual victimization had 51% greater odds of experiencing PND relative to women with no history of sexual victimization (OR = 1.51, 95% CI [1.35, 1.67]). Effect size estimates varied considerably according to the PND instrument used in each study and the racial/ethnic composition of each sample.

CONCLUSION

Findings provide compelling evidence for an association between a lifetime history of sexual victimization and PND. Future research should focus on screening practices and interventions that identify and support survivors of sexual victimization perinatally.

IBC-Ox32 Streamlining preoperative risk assessment: counterintuitive results in the Bariatric patient

Background

Bariatric surgical operations continue to be performed in high numbers nationally, thus it is important to identify factors associated with post-surgical complications. This study aims to identify preoperative risk factors associated with bariatric surgery mortality.

Methods

A retrospective analysis was conducted on the Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program database to determine the strength of association between pre-operative exposures and 30-day mortality following bariatric surgery. A total of 701,265 primary bariatric operations were registered between the years of 2015 and 2017, consisting of sleeve gastrectomy (SG), Roux-en-Y gastric bypass (RYGB), adjustable gastric band (AGB), and duodenal switch (DS)

Results

From the 701,265 surgeries registered in the database, 636,286 had complete data points for the variables of interest and therefore were included in this analysis. The mean age of the cohort was 45.01 (SD= 11.96) years, mean BMI was 45.54 kg/m2 (SD=7.72), and 80.07% were female. Overall 30-day mortality was 0.10% (n=629). The association between the following preoperative variables and mortality within 30 days of bariatric surgery was not statistically significant: hyperlipidemia, history of pulmonary embolism, oxygen dependence, obstructive sleep apnea and history of venous stasis. Smoking status (AOR=1.38), insulin dependent diabetes (AOR=1.37) and the use of more than 3 hypertensive medications (AOR=1.30) were weakly associated with postoperative mortality (p&lt;0.05; CI=95%). History of chronic obstructive pulmonary disease (COPD; AOR=2.00), partial functional dependency (AOR=2.09), renal insufficiency (AOR=1.63), dialysis (AOR=3.15), history of deep venous thrombosis (AOR=1.78), history of myocardial infarction (AOR=1.65) and history of cardiac surgery (AOR=1.87) were strongly associated with mortality (P&lt;0.05; c.i. = 95%)

Conclusion

Bariatric surgery continues to be safe. Many factors that have traditionally been thought to contribute to mortality, such as diabetes, hypertension, smoking, and oxygen dependence may have little impact. Other variables such as previous heart surgery, functional dependency status and COPD may play a bigger role in adverse outcomes. While these associations do not determine causality, understanding the strength of them can guide physicians on preoperative risk assessment and care.

Disparities in dermatology AI performance on a diverse, curated clinical image set

An estimated 3 billion people lack access to dermatological care globally. Artificial intelligence (AI) may aid in triaging skin diseases and identifying malignancies. However, most AI models have not been assessed on images of diverse skin tones or uncommon diseases. Thus, we created the Diverse Dermatology Images (DDI) dataset-the first publicly available, expertly curated, and pathologically confirmed image dataset with diverse skin tones. We show that state-of-the-art dermatology AI models exhibit substantial limitations on the DDI dataset, particularly on dark skin tones and uncommon diseases. We find that dermatologists, who often label AI datasets, also perform worse on images of dark skin tones and uncommon diseases. Fine-tuning AI models on the DDI images closes the performance gap between light and dark skin tones. These findings identify important weaknesses and biases in dermatology AI that should be addressed for reliable application to diverse patients and diseases.

0473 The impact on treatment adherence of adding a bedpartner to CBT-I: preliminary findings from a randomised controlled trial (Project REST)

Introduction

Cognitive Behavioural Therapy for Insomnia (CBT-I) includes often difficult-to-implement behavioural change, and this can result in poor adherence to treatment recommendations. In other CBTs, adding a significant other to “individual” therapy increases adherence. Here, we report preliminary findings from a randomised controlled trial (RCT) of a newly developed partner-assisted CBT-I.

Methods

117 adults with DSM-5 Insomnia Disorder (age M±SD=47.9±15.3yrs; 73F) and their live-in partners participated in a single-blind parallel RCT. They were assigned 1:1:1 to 7wk individual CBT-I (Ind-CBTI), partner-assisted CBT-I (PA-CBTI), or sleep management control (CTRL) conditions. Participants completed daily sleep diary throughout the intervention. Adherence in CBT-I conditions was assessed for Sleep Restriction Therapy (deviation from bed and wake times, naps) and Stimulus Control Therapy (wake time-in-bed during daytime, overnight, and after final morning awakening). Intention-to-treat, mixed effects models examined differences in adherence for “Build” (initial phase to build sleep debt) and “Maintain” (starting the first week when sleep opportunity was titrated upwards) stages of therapy.

Results

All conditions showed significant increase in sleep efficiency (p&lt;.001), with significantly faster increase in Ind-CBTI and PA-CBTI compared to CTRL (ps&lt;.001). Sleep Restriction Therapy: Build stage (vs Maintain) had greater adherence to prescribed wake time (p=.045); Condition by Stage interaction (p=.010) showed PA-CBTI (vs Ind-CBTI) adhered better in avoiding naps during Build (vs Maintain). Stimulus Control Therapy: PA-CBTI (vs Ind-CBTI) adhered better to avoiding daytime wake time-in-bed (p=.017), especially during Build (interaction p=.071); Condition by Stage interaction (p=.017) showed PA-CBTI (vs Ind-CBTI) adhered better to avoiding overnight wake time-in-bed during Maintain (vs Build). Both conditions had better adherence to avoiding daytime and wake time-in-bed after final awakening during Maintain (vs Build) Stage (ps&lt;.001).

Conclusion

Adherence to CBT-I includes multiple indicators showing distinct features as the intervention progresses across different stages. Aspects of adherence appear modifiable, and adding bedpartners to CBT-I improved adherence to specific aspects of the intervention (i.e., avoiding naps, daytime wake time-in-bed, overnight wake time-in-bed). The Build and Maintain stages of treatment appear to be associated with better adherence to different aspects of the intervention (Sleep Restriction Therapy and Stimulus Control Therapy, respectively).

708 A 360 Degree Exploration of Key Factors in Consent in Aortic Aneurysm Repair

Introduction

Shared decision making is the gold standard for treatment decisions. Although there is an evidence base to recommend either open surgical repair or endovascular repair (EVAR) for patients with abdominal aortic aneurysms (AAA) based on individual outcome factors, there is scope for choice depending on subjective factors. This study aims to identify key factors to be addressed in the consent process using a 360-degree exploration.

Method

A literature search conducted on Medline and Embase databases identified 13 key factors, which were formulated into questions with five-point Likert scales. Seven vascular surgeons, two interventional radiologists, two vascular anaesthetists, two intensivists, one vascular physician, and five patients who underwent either open surgical repair or EVAR were interviewed in a semi-structured manner. Descriptive statistical analysis was performed to identify the importance of each factor.

Results

The most important factors for clinicians and patients were “pre-existing medical conditions” and “risk of post-operative complications”. The least important factors were “need for follow-up appointments” and “post-operative pain”. Patients placed the most importance on “type of anaesthetic used”, and relatively less importance on “length of hospital stay” and “probability of admission to ICU”. Analysis of free-flowing answers yielded another 14 factors. Factors were grouped into “surgical focus”, “medical and perioperative focus” and “patients and communication”.

Conclusions

There is heterogeneity in the importance given to factors between clinicians and patients. The factors identified from this 360-degree assessment should be integrated into formal topics of discussion in the consent process to support patients in making informed decisions regarding AAA treatment.

COVID-related anxiety is prevalent and accurately reflects serious COVID risks in breast cancer patients

12053

Background: A current cancer diagnosis is a risk factor for serious COVID-19 complications (CDC). In addition, the pandemic has caused major disruptions in medical care and support networks, resulting in treatment delays, limited access to doctors, worsening health disparities, social isolation; and driving higher utilization of telemedicine and online resources. Breastcancer.org has experienced a sustained surge of new and repeat users seeking urgent information and support. To better understand these unmet needs, we conducted a survey of the Breastcancer.org Community. Methods: Members of the Breastcancer.org Community were invited to complete a survey on the effects of the COVID-19 pandemic on their breast cancer care, including questions on demographics, comorbidities (including lung, heart, liver and kidney disease, asthma, diabetes, obesity, and other chronic health conditions); care delays, anxiety due to COVID-related care delays, use of telemedicine, and satisfaction with care during COVID. The survey was conducted between 4/27/2020-6/1/2020 using Survey Monkey. Results were tabulated and compared by chi square test. A p-value of 0.05 is considered significant. Data were analyzed using Stata 16.0 (Stata Corp., Inc, College Station, TX). Results: Our analysis included 568 breast cancer patients of whom 44% had ≥1 other comorbidities associated with serious COVID-19 complications (per CDC) and 37% had moderate to extreme anxiety about contracting COVID. This anxiety increased with the number of comorbidities (p=0.021), age (p=0.040), and with a current breast cancer diagnosis (p=0.011) (see table). Anxiety was significantly higher in those currently diagnosed, ≥65, or with ≥3 other comorbidities, compared to those diagnosed in the past, age <44, or without other comorbidities. Conclusions: Our survey reveals that COVID-related anxiety is prevalent at any age regardless of overall health status, but it increased with the number of other comorbidities, older age, and a current breast cancer diagnosis. Thus, reported anxiety is proportional to the risk of developing serious complications from COVID. Current breast cancer patients of all ages—especially with other comorbidities—require emotional support, safe access to their providers, and prioritization for vaccination.[Table: see text]

Fire safety and emergency evacuation guidelines for intensive care units and operating theatres: for use in the event of fire, flood, power cut, oxygen supply failure, noxious gas, structural collapse or other critical incidents: Guidelines from the Association of Anaesthetists and the Intensive Care Society

The need to evacuate an ICU or operating theatre complex during a fire or other emergency is a rare event but one potentially fraught with difficulty: Not only is there a risk that patients may come to harm but also that staff may be injured and unable to work. Designing newly-built or refurbished ICUs and operating theatre suites is an opportunity to incorporate mandatory fire safety features and improve the management and outcomes of such emergencies: These include well-marked manual fire call points and oxygen shut off valves (area valve service units); the ability to isolate individual zones; multiple clear exit routes; small bays or side rooms; preference for ground floor ICU location and interconnecting routes with operating theatres; separate clinical and non-clinical areas. ICUs and operating theatre suites should have a bespoke emergency evacuation plan and route map that is readily available. Staff should receive practical fire and evacuation training in their clinical area of work on induction and annually as part of mandatory training, including 'walk-through practice' or simulation training and location of manual fire call points and fire extinguishers, evacuation routes and location and operation of area valve service units. The staff member in charge of each shift should be able to select and operate fire extinguishers and lead an evacuation. Following an emergency evacuation, a network-wide response should be activated, including retrieval and transport of patients to other ICUs if needed. A full investigation should take place and ongoing support and follow-up of staff provided.

Effect on Patients’ Outcomes of a Change to Biosimilar Filgrastim Product in Autologous Stem Cell Mobilization

Background: Following addition of a biosimilar filgrastim product to the formulary, sites in the authors’ provincial health authority transitioned from using the originator filgrastim to the biosimilar for autologous stem cell mobilization. Objective: To assess the effect on patient outcomes of a universal change to use of the biosimilar filgrastim in stem cell mobilization. Methods: This retrospective pre–post study included patients undergoing autologous stem cell mobilization at 2 cancer hospitals in Alberta, Canada, between July 1, 2018, and November 30, 2019. Clinical outcomes were investigated for patients treated with a granulocyte colony-stimulating factor (biosimilar or originator product) for mobilization before stem cell transplant, approximately 6 months before and after the defined date of product change. Results: In total, 102 patients were treated with the originator product and 101 patients with the biosimilar. Effectiveness was similar between the originator and biosimilar products, with 98% successful harvest of stem cells in all patients treated. Independent t tests showed no statistically significant differences between patients receiving the originator and those receiving the biosimilar in terms of time from mobilization to collection (difference of means –0.9 days, 95% confidence interval [CI] –2.12 to 0.32), time for neutrophil engraftment (difference of means 0 days, 95% CI –0.36 to 0.36), time for platelet engraftment (difference of means 1 day, 95% CI –0.55 to 2.55), average length of stay (difference of means –0.7 day, 95% CI –2.71 to 1.31), and CD34+ value (difference of means –1 × 106/kg body weight, 95% CI –2.11 to 0.11). A 98% rate of conversion to use of the biosimilar filgrastim was achieved, with an estimated annual drug-cost saving of $67 500. Conclusions: In this pre–post study, changing to the biosimilar product from the originator maintained clinical effectiveness outcomes while decreasing overall drug expenditures. A well-planned change to the biosimilar product, executed in conjunction with clinician consultation and monitoring of effectiveness outcomes, can ensure appropriate patient therapy while significantly improving the uptake of biosimilars and decreasing expenditures for biologic drugs. RÉSUMÉ Contexte : À la suite de l’ajout d’un produit filgrastim biosimilaire à la liste des médicaments, les sites relevant de l’autorité sanitaire provinciale des auteurs sont passés de l’utilisation du filgrastim princeps à la version générique pour la mobilisation des cellules souches autologues. Objectif : Évaluer l’effet sur les résultats des patients d’un changement généralisé visant à utiliser le filgrastim générique pour la mobilisation des cellules souches. Méthodes : Cette étude rétrospective pré-post comprenait des patients soumis à une mobilisation des cellules souches autologues dans deux hôpitaux de cancérologie en Alberta (Canada) entre le 1er juillet 2018 et le 30 novembre 2019. L’examen des résultats cliniques des patients traités à l’aide d’un facteur stimulant les colonies de granulocytes (G-CSF) (générique ou princeps) pour une mobilisation avant la greffe de cellules souches a eu lieu environ six mois avant et après la date du changement de produit. Résultats : Au total, 102 patients ont été traités à l’aide du produit princeps et 101 patients à l’aide du générique. Les deux produits présentaient une efficacité similaire, et 98 % de réussite dans la récolte de cellules souches chez tous les patients traités. Des tests t indépendants n’ont montré aucune différence statistique significative entre les patients recevant le princeps et ceux recevant le biosimilaire en termes de temps allant de la mobilisation à la collecte (différence des moyennes –0,9 jour, intervalle de confiance [IC] 95 % –2,12 à 0,32); temps de la prise de la greffe neutrophile (différence des moyennes 0 jour, IC 95 % –0,36 à 0,36); temps de la prise de la greffe des plaquettes (différence des moyennes 1 jour, IC 95 % –0,55 à 2,55); durée moyenne du séjour (différence des moyennes –0,7 jour, IC 95 % –2,71 à 1,31) et valeur CD34+ (différence des moyennes –1 × 106/kg masse corporelle, IC 95 % –2,11 à 0,11). Un taux de conversion de 98 % visant à utiliser le filgrastim générique a été atteint, avec une estimation des économies annuelles sur le coût des médicaments de 67 500 $. Conclusions : Dans cette étude pré-post, le passage du produit princeps au générique a préservé l’efficacité des résultats cliniques, tout en diminuant les dépenses générales liées au médicament. Un changement bien programmé pour passer au produit générique, mené conjointement avec la consultation d’un clinicien et un contrôle des résultats d’efficacité, peut assurer une thérapie du patient appropriée tout en améliorant grandement la prise de produits génériques et en diminuant les dépenses associées aux médicaments biologiques.

The Christchurch mosque shooting, the media, and subsequent gun control reform in New Zealand: a descriptive analysis

In March 2019, a mass shooting at two Christchurch mosques, livestreamed to Facebook, resulted in the deaths of 51 people. Psychologically, this served as a focusing event with high threat salience, shocking a country unused to gun violence despite its comparatively lax firearm legislation. The unprecedented reluctance by the New Zealand media to feature the shooter as a protagonist or even publish his name, concentrating instead on victims and societal issues, helped promote a sense of collective responsibility for change. This was strongly modeled by political leaders. Within weeks, new gun control laws were introduced with bipartisan support. We present this as a national case study, considering psychological and societal enablers for legislative reform in response to extreme gun violence. The shooting also raised the intractable problem of the internet allowing terrorists to promulgate violent content and extremist ideology with regulation in this area harder to achieve than gun control.

A survey of cannabis use for symptom palliation in breast cancer patients by age and stage

12108

Background: Most US states have legalized medical cannabis for the treatment of serious conditions, including cancer. It is not well known which symptoms breast cancer patients seek to control with cannabis. Methods: Members of the Breastcancer.org and Healthline communities were invited to participate in this survey between 12/16/2019 and 1/19/2020. Eligibility criteria included age ≥18 years, resident of the US and a breast cancer diagnosis within the past 5 years. Eligible respondent data were analyzed for the symptomatic profile of cannabis users. Symptoms were compared between two groups using a Chi-square test of independence. The survey was led by Socanna, conducted by Outcomes Insights, and supported by a grant from Ananda Health/Ecofibre. Results: Among the 832 respondents who completed screening, 725 met the eligibility criteria, and 612 (84%) completed the survey. The median age of respondents was 57 years, and 85% had non-metastatic disease An estimated 42% of respondents have used medical cannabis to treat symptoms or side effects of breast cancer. Medical cannabis users reported using cannabis to treat insomnia (70%), joint and muscle aches, discomfort, stiffness, or pain (59%), anxiety (57%), and stress (51%). The medical cannabis users less than 50-year-old were more likely to use cannabis to treat these symptoms than their over 50-year-old counterparts, however, the differences were not statistically significant. Medical cannabis users under age 50 used cannabis significantly more than over 50 to treat nausea/vomiting (58% vs 40%; p = 0.010) and inflammation (34% vs 20%; p = 0.021). Medical cannabis users with metastatic disease were more likely to use medical cannabis to treat chronic pain 60% vs 41%; p = 0.017) than non-metastatic users. Post-surgery patients were most likely to use cannabis for nerve pain; and those who were beyond treatment, for stress. Patients suffered an average of 5 symptoms. Conclusions: A significant proportion of breast cancer patients reported using cannabis to treat a combination of symptoms from their cancer and its treatment. Although younger patients are somewhat more likely to use this form of palliative management, older patients are suffering from the same symptoms and their use is nearly as high. More research is needed on the personalization of safe and effective symptomatic management with medical cannabis, for people of all ages, stages, and forms of treatment.

Hyperhomocysteinemia and Pulmonary Embolism in a Young Male

The association of hyperhomocysteinemia with thrombosis has provoked debate in the medical literature. Although studies have found associations between moderate homocysteine elevations and thrombotic events, others dispute this relationship. We present herein the case of a 24-year-old male who presented with unprovoked bilateral submassive pulmonary emboli. Extensive hypercoagulability workup was notable for an elevated homocysteine level, in addition to low vitamin B12 and folate levels. Of note, the patient had a history of small bowel resection after trauma, which may have contributed to the aforementioned metabolic derangements, potentially increasing his risk for thrombosis and interfering with the efficacy of his anticoagulation.

Meeting report from the joint IARC-NCI international cancer seminar series: a focus on colorectal cancer

Despite significant progress in our understanding of the etiology, biology and genetics of colorectal cancer, as well as important clinical advances, it remains the third most frequently diagnosed cancer worldwide and is the second leading cause of cancer death. Based on demographic projections, the global burden of colorectal cancer would be expected to rise by 72% from 1.8 million new cases in 2018 to over 3 million in 2040 with substantial increases anticipated in low- and middle-income countries. In this meeting report, we summarize the content of a joint workshop led by the National Cancer Institute and the International Agency for Research on Cancer, which was held to summarize the important achievements that have been made in our understanding of colorectal cancer etiology, genetics, early detection and treatment and to identify key research questions that remain to be addressed.

Abstract P5-14-03: Patient perspectives on HER2+ breast cancer recurrence: Results from an online patient survey

Background: The objective of this study was to gather insights from patients with early-stage HER2+ breast cancer regarding fears and knowledge of breast cancer recurrence and approaches to reducing risk of recurrence.

Methods: From Nov. 7-30, 2017, patients with stage I-IIIC HER2+ breast cancer were recruited via postings to Breastcancer.org discussion boards to participate in an online survey comprising 17 questions designed to quantify fears and emotions related to recurrence, identify and characterize knowledge gaps, and understand what patients are willing to tolerate to reduce recurrence risk.

Results: Of 307 respondents, 87% were aged ≥40 years and over half were ≥50 (58%). The majority had completed (48%) or were undergoing (39%) postsurgical treatment. Recurrence was a concern for 93% of patients and was the highest rated concern for 78%; however, most patients (76%) perceived their personal risk of recurrence to be moderate or low. 59% of patients felt they were at least somewhat informed about risk of recurrence; 55% had discussed risk of recurrence with their health care team, with discussions most frequently initiated by the patient (56%) vs the health care team (40%). Oncologists were the primary source of information about risk of recurrence (58%), but patients also frequently sourced information from online content (29%), published research (18%), and Breastcancer.org (15%). Almost all (96%) patients were at least somewhat involved in treatment planning. While 55% of patients would inquire about a new drug if it conferred a 10%-20% reduction in risk of recurrence, 26% required a benefit of ≥50%. For treatments reducing the risk of recurrence, patients were willing to tolerate (in order from most to least willing) hot flashes, fatigue, diarrhea, joint pain, and nausea/vomiting.

Conclusions: While patients with HER2+ breast cancer are highly concerned about recurrence, most feel that their personal risk is moderate. Patients are highly engaged in treatment planning, often initiate discussions about risk of recurrence, and supplement their knowledge with their own research. The threshold to motivate inquiry into a new drug to reduce recurrence risk was &lt;20% for over half of patients. Patients were also frequently willing to tolerate common adverse events.
