RESUMEN

OBJECTIVE: Patients may use emergency departments (EDs) to meet their health needs when ambulatory care systems are not sufficient. We aim to describe contributing factors to the decision made by persons with inflammatory arthritis (IA) to present to the ED, as well as their experiences of ED care and postdischarge follow-up. METHODS: An embedded mixed-methods approach was taken to contextualize quantitative data with associated free-text responses from an online survey distributed to residents of Alberta with a known IA condition and an ED visit. RESULTS: Eighty-two persons (63% aged 16-55 years, 48% female, 50% urban residents) with rheumatoid arthritis (48%), psoriatic arthritis (12%), spondyloarthritis (6%), or gout (34%) completed the survey. Presenting concerns were arthritis flare (37%), chest pain (15%), injury (12%), and infection (11%). Of all visits, 29% proceeded directly to the ED, 35% attempted accessing ambulatory care first, and 32% arrived for a return visit. In presentations for arthritis flare, patients were aware of the rheumatology service being contacted by the ED provider for advice in just 9% of events. Challenges in healthcare system coordination and system pressures resulted in patients requiring ED attendance to assess their concern. The quality of communication and relationality developed between patients with IA and healthcare providers informed experiences of ED care. CONCLUSION: Modifying rheumatology ambulatory care models could better meet patient needs and ultimately reduce avoidable ED use by patients with IA.

RESUMEN

PURPOSE: To test the hypothesis that Pressure-Enabled Drug Delivery (PEDD) would improve the delivery of surrogate therapeutic glass microspheres (GMs) via hepatic artery infusion to liver tumors when compared with a conventional endhole microcatheter. MATERIALS AND METHODS: The study was conducted in transgenic pigs (Oncopigs) with induced liver tumors. Tumors were infused intra-arterially with fluorescently labeled GM. PEDD with a specialized infusion device (TriNav; TriSalus Life Sciences, Westminster, Colorado) was compared with conventional endhole microcatheter delivery in both lobar and selective infusions. Near-infrared imaging was used to detect GM fluorescent signal in tumors. Image analysis with a custom deep learning algorithm (Visiopharm A/S) was used to quantitate signal intensity in relation to the tumor border. RESULTS: With lobar infusions, significant increases in GM signal intensity were observed in and around tumors after PEDD (n = 10) when compared with those after conventional delivery (n = 7), with PEDD increasing penetration into the tumor by 117% (P = .004). In selective infusions, PEDD (n = 9) increased penetration into the tumor by 39% relative to conventional delivery (n = 8, P = .032). Lobar PEDD of GMs to the tumor was statistically equivalent to conventional selective delivery (P = .497). CONCLUSIONS: PEDD with a TriNav device significantly improved GM uptake in liver tumors relative to conventional infusion in both lobar and selective procedures. Lobar GM delivery with PEDD was equivalent to conventional selective delivery with an endhole device, suggesting that proximal PEDD infusions may enable effective delivery without selection of distal target vessels.

RESUMEN

BACKGROUND: Care complexity can occur when patients experience health challenges simultaneously with social barriers including food and/or housing insecurity, lack of transportation or other factors that impact care and patient outcomes. People with rheumatoid arthritis (RA) may experience care complexity due to the chronicity of their condition and other biopsychosocial factors. There are few standardised instruments that measure care complexity and none that measure care complexity specifically in people with RA. OBJECTIVES: We assessed the content validity of the INTERMEDS Self-Assessment (IMSA) instrument that measures care complexity with a sample of adults with RA and rheumatology healthcare providers (HCPs). Cognitive debriefing interviews utilising a reparative framework were conducted. METHODS: Patient participants were recruited through two existing studies where participants agreed to be contacted about future studies. Study information was also shared through email blasts, posters and brochures at rheumatology clinic sites and trusted arthritis websites. Various rheumatology HCPs were recruited through email blasts, and divisional emails and announcements. Interviews were conducted with nine patients living with RA and five rheumatology HCPs. RESULTS: Three main reparative themes were identified: (1) Lack of item clarity and standardisation including problems with item phrasing, inconsistency of the items and/or answer sets and noninclusive language; (2) item barrelling, where items asked about more than one issue, but only allowed a single answer choice; and (3) timeframes presented in the item or answer choices were either too long or too short, and did not fit the lived experiences of patients. Items predicting future healthcare needs were difficult to answer due to the episodic and fluctuating nature of RA. CONCLUSIONS: Despite international use of the IMSA to measure care complexity, patients with RA and rheumatology HCPs in our setting perceived that it did not have content validity for use in RA and that revision for use in this population under a reparative framework was unfeasible. Future instrument development requires an iterative cognitive debriefing and repair process with the population of interest in the early stages to ensure content validity and comprehension. PATIENT OR PUBLIC CONTRIBUTION: Patient and public contributions included both patient partners on the study team and people with RA who participated in the study. Patient partners were involved in study design, analysis and interpretation of the findings and manuscript preparation. Data analysis was structured according to emergent themes of the data that were grounded in patient perspectives and experiences.

RESUMEN

Some emergency department (ED) visits by persons with rheumatoid arthritis (RA) may be avoidable. This study aims to describe ED use by persons with RA in Alberta, Canada over a 10-year period. Using linked population-based administrative datasets, the annual frequency of ED visits, timing of visits, acuity at presentation assessed (Canadian Triage Acuity Scale (CTAS)), return visits within 72 h, and final disposition were assessed. Most responsible diagnoses assessed by the ED provider were categorized. Between 2008 and 2017, a total of 48,633 persons with RA had 416,964 unique ED visits. There was a 41% relative increase in visits over the study period and within a fiscal year 37% of persons with RA on average attended an ED. Half of the visits were assessed as CTAS 4 'Less Urgent' (31%) and CTAS 5 'Non-Urgent' (19%). No specific diagnosis could be assigned in 36% of visits and RA was listed as the most responsible diagnosis in 2.5% of all visits. Hospital admissions, occurring on average for 14% of ED visits, increased by 15% over the 10 years, and were rare for CTAS 4 (6.4%) and CTAS 5 (1.4%) presentations. Male patients (difference to female 1.2%, 95%CI 0.6, 1.7) and urban patients (difference to rural 8.4%, 95%CI 7.7, 9.2) were more frequently admitted to hospital. Persons with RA have increased ED utilization over time, with a significant volume of less urgent and non-urgent visits. Opportunities for appropriate ambulatory care provision to reduce acute care use should be identified.

RESUMEN

OBJECTIVE: Programmed cell death protein 1 (PD-1) checkpoint inhibition and adoptive cellular therapy have had limited success in patients with microsatellite stable colorectal cancer liver metastases (CRLM). We sought to evaluate the effect of interleukin 10 (IL-10) blockade on endogenous T cell and chimeric antigen receptor T (CAR-T) cell antitumour function in CRLM slice cultures. DESIGN: We created organotypic slice cultures from human CRLM (n=38 patients' tumours) and tested the antitumour effects of a neutralising antibody against IL-10 (αIL-10) both alone as treatment and in combination with exogenously administered carcinoembryonic antigen (CEA)-specific CAR-T cells. We evaluated slice cultures with single and multiplex immunohistochemistry, in situ hybridisation, single-cell RNA sequencing, reverse-phase protein arrays and time-lapse fluorescent microscopy. RESULTS: αIL-10 generated a 1.8-fold increase in T cell-mediated carcinoma cell death in human CRLM slice cultures. αIL-10 significantly increased proportions of CD8+ T cells without exhaustion transcription changes, and increased human leukocyte antigen - DR isotype (HLA-DR) expression of macrophages. The antitumour effects of αIL-10 were reversed by major histocompatibility complex class I or II (MHC-I or MHC-II) blockade, confirming the essential role of antigen presenting cells. Interrupting IL-10 signalling also rescued murine CAR-T cell proliferation and cytotoxicity from myeloid cell-mediated immunosuppression. In human CRLM slices, αIL-10 increased CEA-specific CAR-T cell activation and CAR-T cell-mediated cytotoxicity, with nearly 70% carcinoma cell apoptosis across multiple human tumours. Pretreatment with an IL-10 receptor blocking antibody also potentiated CAR-T function. CONCLUSION: Neutralising the effects of IL-10 in human CRLM has therapeutic potential as a stand-alone treatment and to augment the function of adoptively transferred CAR-T cells.

RESUMEN

PURPOSE: Little is known about the factors contributing to the receipt of non-recommended surveillance testing among early-stage breast cancer survivors. We assessed primary care providers (PCP) attitudes about and tendency to order non-recommended surveillance testing for asymptomatic early-stage breast cancer survivors post-adjuvant chemotherapy. METHODS: A stratified random sample of PCPs identified by early-stage breast cancer survivors were surveyed (N = 518, 61% response rate). PCPs were asked how likely they would be to order bone scans, imaging and/or tumor marker testing using a clinical vignette of an early-stage asymptomatic patient where these tests are non-recommended. A composite tendency to order score was created and categorized by tertiles (low, moderate, high). PCP-reported factors associated with high and moderate tendency to order non-recommended testing (vs. low) were estimated using multivariable, multinomial logistic regression. RESULTS: In this sample, 26% reported a high tendency to order non-recommended surveillance tests during survivorship for early-stage breast cancer survivors. PCPs who identified as family practice physicians and PCPs reporting more confidence in ordering surveillance testing were more likely to report a high tendency to order non-recommended testing (vs. low) ((aOR family practice 2.09, CI 1.2, 3.8; aOR more confidence 1.9, CI 1.1, 3.3). CONCLUSIONS: In this population-based sample of PCPs caring for breast cancer survivors, over a quarter of PCPs reported they would order non-recommended surveillance testing for asymptomatic early-stage breast cancer survivors. Efforts to better support PCPs and disseminate information about appropriate surveillance for cancer survivors are warranted.

RESUMEN

Importance: Germline genetic testing is recommended by practice guidelines for patients diagnosed with cancer to enable genetically targeted treatment and identify relatives who may benefit from personalized cancer screening and prevention. Objective: To describe the prevalence of germline genetic testing among patients diagnosed with cancer in California and Georgia between 2013 and 2019. Design, Setting, and Participants: Observational study including patients aged 20 years or older who had been diagnosed with any type of cancer between January 1, 2013, and March 31, 2019, that was reported to statewide Surveillance, Epidemiology, and End Results registries in California and Georgia. These patients were linked to genetic testing results from 4 laboratories that performed most germline testing for California and Georgia. Main Outcomes and Measures: The primary outcome was germline genetic testing within 2 years of a cancer diagnosis. Testing trends were analyzed with logistic regression modeling. The results of sequencing each gene, including variants associated with increased cancer risk (pathogenic results) and variants whose cancer risk association was unknown (uncertain results), were evaluated. The genes were categorized according to their primary cancer association, including breast or ovarian, gastrointestinal, and other, and whether practice guidelines recommended germline testing. Results: Among 1 369 602 patients diagnosed with cancer between 2013 and 2019 in California and Georgia, 93 052 (6.8%) underwent germline testing through March 31, 2021. The proportion of patients tested varied by cancer type: male breast (50%), ovarian (38.6%), female breast (26%), multiple (7.5%), endometrial (6.4%), pancreatic (5.6%), colorectal (5.6%), prostate (1.1%), and lung (0.3%). In a logistic regression model, compared with the 31% (95% CI, 30%-31%) of non-Hispanic White patients with male breast cancer, female breast cancer, or ovarian cancer who underwent testing, patients of other races and ethnicities underwent testing less often: 22% (95% CI, 21%-22%) of Asian patients, 25% (95% CI, 24%-25%) of Black patients, and 23% (95% CI, 23%-23%) of Hispanic patients (P < .001 using the χ2 test). Of all pathogenic results, 67.5% to 94.9% of variants were identified in genes for which practice guidelines recommend testing and 68.3% to 83.8% of variants were identified in genes associated with the diagnosed cancer type. Conclusions and Relevance: Among patients diagnosed with cancer in California and Georgia between 2013 and 2019, only 6.8% underwent germline genetic testing. Compared with non-Hispanic White patients, rates of testing were lower among Asian, Black, and Hispanic patients.

RESUMEN

BACKGROUND: Despite mandated insurance coverage for breast reconstruction following mastectomy, health care costs are increasingly passed on to women through cost-sharing arrangements and high-deductible health plans. In this population-based study, the authors assessed perceived financial and employment declines related to breast reconstruction following mastectomy. METHODS: Women with early-stage breast cancer (stages 0-II) diagnosed between July 2013 and May 2015 who underwent mastectomy were identified through the Surveillance, Epidemiology, and End Results registries of Georgia and Los Angeles and were surveyed. Primary outcome measures included patients' appraisal of their financial and employment status after cancer treatment. Multivariable models evaluated the association between breast reconstruction and primary outcomes. RESULTS: Among 883 patients with breast cancer who underwent mastectomy, 44.2% did not undergo breast reconstruction, and 55.8% underwent reconstruction. Overall, 21.9% of the cohort reported being worse off financially since their diagnosis (25.8% with reconstruction vs 16.6% without reconstruction; P = .002). Women who underwent reconstruction reported higher out-of-pocket medical expenses (32.1% vs 15.6% with expenses greater than $5000; P < .001). Reconstruction was independently associated with a perceived decline in financial status (odds ratio, 1.92; 95% confidence interval, 1.15-3.22; P = .013). Among women who were employed at the time of their diagnosis, there was no association between reconstruction and a perceived decline in employment status (P = .927). CONCLUSIONS: In this diverse cohort of women who underwent mastectomy, those who elected to undergo reconstruction experienced higher out-of-pocket medical expenses and self-reported financial decline. Patients, providers, and policymakers should be aware of the potential financial implications related to reconstruction despite mandatory insurance coverage.

RESUMEN

BACKGROUND: Effective treatment of solid tumors requires multi-modality approaches. In many patients with stage IV liver disease, current treatments are not curative. Chimeric antigen receptor T cells (CAR-T) are an intriguing option following success in hematological malignancies, but this has not been translated to solid tumors. Limitations include sub-optimal delivery and elevated interstitial fluid pressures. We developed a murine model to test the impact of high-pressure regional delivery (HPRD) on trafficking to liver metastases (LM) and tumor response. MATERIALS AND METHODS: CAR-T were generated from CD45.1 mice and adoptively transferred into LM-bearing CD45.2 mice via regional or systemic delivery (RD, SD). Trafficking, tumor growth, and toxicity were evaluated with flow cytometry, tumor bioluminescence (TB, photons/sec log2-foldover baseline), and liver function tests (LFTs). RESULTS: RD of CAR-T was more effective at controlling tumor growth versus SD from post-treatment days (PTD) 2-7 (P = 0.002). HPRD resulted in increased CAR-T penetration versus low-pressure RD (LPRD, P = 0.004), suppression of tumor proliferation (P = 0.03), and trended toward improved long-term control at PTD17 (TB=3.7 versus 6.1, P = 0.47). No LFT increase was noted utilizing HPRD versus LPRD (AST/ALT P = 0.65/0.84) while improved LFTs in RD versus SD groups suggested better tumor control (HPRD AST/ALT P = 0.04/0.04, LPRD AST/ALT P = 0.02/0.02). CONCLUSIONS: Cellular immunotherapy is an emerging option for solid tumors. Our model suggests RD and HPRD improved CAR-T penetration into solid tumors with improved short-term tumor control. Barriers associated with SD can be overcome using RD techniques to maximize therapeutic delivery and HPRD may further augment efficacy without increased toxicity.

RESUMEN

BACKGROUND: Patients are increasingly turning to the Internet for health guidance, requiring awareness from clinicians of constantly changing resources and quality of available information. A previous study demonstrated a minority of YouTube videos were useful for teaching methotrexate (MTX) self-injection; however, YouTube content constantly evolves, and previous results may not represent current videos. This study provides an update on previous work from 2014 evaluating the quality of YouTube videos demonstrating self-administered subcutaneous MTX injections. Our aim was to evaluate how YouTube videos on MTX injection have changed and evaluate the current video quality. METHODS: "Methotrexate injection" was searched on YouTube. The first 75 videos were analyzed independently by 2 reviewers. Videos were classified as useful, misleading/irrelevant, or a personal patient view and rated for reliability, comprehensiveness, and quality. RESULTS: Of the 75 videos reviewed, 12 were classified as useful (16%), 43 misleading/irrelevant (57.3%), and 20 personal patient views (26.7%). Although this represents a substantial increase from previous results in the proportion of videos deemed misleading/irrelevant (57.3% vs. 27.5%) ( p = 0.0011), their reliability and global quality scores were higher. CONCLUSIONS: Concordant with the previous study, only a small proportion of the total videos were deemed useful videos for MTX injection specifically. However, reliability and global quality scores for all videos increased from the previous study, suggesting more videos provide reliable information with regard to MTX overall, even if it does not speak to self-injection directly. Logistics of the YouTube algorithm may still impede access to the "best" videos for patient teaching; therefore, clinicians should be prepared to recommend strategies for patients to find high-quality videos.

RESUMEN

PURPOSE: We developed and tested a multi-level intervention, ConnectedCancerCare (CCC), which includes a tailored website and appointment reminder system for women with early-stage breast cancer and a provider summary letter sent to their medical oncologist and primary care provider to improve the delivery of team-based survivorship care. METHODS: We conducted a pilot randomized controlled trial to establish the feasibility and acceptability of CCC. Women diagnosed with stages 0-II breast cancer within one year of completing primary treatment were randomized to CCC (intervention) or a static online survivorship care plan (control). Participants completed baseline and 3-month follow-up surveys online. Post-trial interviews with 5 PCPs, 6 oncology providers, and 8 intervention patients were conducted. RESULTS: Of the 160 eligible women invited to participate, 66 completed the baseline survey and were randomized (41%) and 54 completed a follow-up survey (83%). Participants in the intervention arm found the CCC content to be acceptable, with 82% reporting it was easy to use and 86% reporting they would recommend it to other patients. Women randomized to CCC (vs. control) more often reported scheduling a PCP follow-up visit (64% vs. 42%), communicating with their PCP about provider roles (67% vs. 18%), and higher mean team-based cancer care knowledge scores (3.7 vs. 3.4). CONCLUSION: Deploying CCC in medical oncology practices was feasible, and the intervention content was acceptable. CCC shows promise for improving patient knowledge and patient-provider communication about provider roles in team-based cancer care and encouraging patients to engage with their PCP early in the survivorship period.

RESUMEN

OBJECTIVE: Primary nitinol stenting (PNS) and drug-coated balloon (DCB) angioplasty are two of the most common endovascular interventions for femoropopliteal atherosclerotic disease. Although many prospective randomized controlled trials have compared PNS or DCB with plain balloon angioplasty (POBA), no studies have directly compared PNS against DCB therapy. The purpose of this network meta-analysis is to determine whether there is a significant difference in outcomes between PNS and DCB. METHODS: The primary outcome measure was binary restenosis, the secondary outcome measures were target lesion revascularization (TLR) and change in the ankle-brachial index (ABI). Outcomes were evaluated at 6, 12, and 24 months. A literature review identified all randomized controlled trials published before March 2020 that compared DCB with POBA or PNS with POBA in the treatment of native atherosclerotic lesions of the femoropopliteal artery. Studies were excluded if they contained in-stent stenosis or tibial artery disease that could not be delineated out in a subgroup analysis. Network meta-analysis was performed using the network and mvmeta commands in STATA 14. RESULTS: Twenty-seven publications covering 19 trials were identified; 8 trials compared PNS with POBA and 11 trials compared DCB with POBA. The odds of freedom from binary restenosis for patients treated with DCB compared with PNS at 6 months was 1.19 (95% confidence interval [CI], 0.63-2.22), at 12 months was 1.67 (95% CI, 1.04-2.68), and at 24 months was 1.36 (95% CI, 0.78-2.37). The odds of freedom from TLR for patients treated with DCB compared with PNS at 6 months was 0.66 (95% CI, 0.12-3.80), at 12 months was 1.89 (95% CI, 1.04-3.45), and at 24 months was 1.68 (95% CI, 0.82-3.44). The mean increase in ABI for patients treated with PNS compared with DCB at 6 months was 0.06 higher (95% CI, -0.03 to 0.15), at 12 months was 0.05 higher (95% CI, 0.00-0.09), and at 24 months was 0.07 higher (95% CI, -0.01 to 0.14). CONCLUSIONS: Both DCB and PNS demonstrated a lower rate of binary restenosis compared with POBA at the 6-, 12-, and 24-month timepoints. When comparing DCB with PNS through network meta-analysis, DCB had a statistically lower rate of a binary restenosis and TLR at the 12-month timepoint. This network meta-analysis demonstrates that both DCB and PNS are superior to POBA, and that PNS is a satisfactory substitute for DCB when paclitaxel is not desirable.

RESUMEN

BACKGROUND: Primary care provider's (PCP) role in cancer care is expanding and may include supporting patients in their treatment decisions. However, the degree to which PCPs engage in this role for low-risk prostate cancer is unknown. OBJECTIVE: Characterize PCP perceptions regarding their role in low-risk prostate cancer treatment decision-making. DESIGN: Cross-sectional, national survey. MAIN MEASURES: For men with low-risk prostate cancer, PCP reports of (1) confidence in treatment decision-making (high vs. low); (2) intended participation in key aspects of active surveillance treatment decision-making (more vs. less). KEY RESULTS: A total of 347 from 741 eligible PCPs responded (adjusted response rate 56%). Half of respondent PCPs (50.3%) reported high confidence about engaging in low-risk prostate cancer treatment decision-making. The odds of PCPs reporting high confidence were greater among those in solo practice (vs working with > 1 PCP) (OR 2.18; 95% CI 1.14-4.17) and with higher volume of prostate cancer patients (> 15 vs. 6-10 in past year) (OR 2.16; 95% CI 1.02-4.61). PCP report of their intended participation in key aspects of active surveillance treatment decision-making varied: discussing worry (62.4%), reviewing benefits (48.5%) and risks (41.8%), and reviewing all treatment options (34.2%). PCPs who reported high confidence had increased odds of more participation in all aspects of active surveillance decision-making: reviewing all treatment options (OR 3.11; 95% CI 1.82-5.32), discussing worry (OR 2.12; 95% CI 1.28-3.51), and reviewing benefits (OR 3.13; 95% CI 1.89-5.16) and risks (OR 3.20; 95% CI 1.91-5.36). CONCLUSIONS: The majority of PCPs were confident about engaging with patients in low-risk prostate cancer treatment decision-making, though their intended participation varied widely across four key aspects of active surveillance care. With active surveillance being considered for other low-risk cancers (such as breast and thyroid), understanding factors influencing PCP involvement will be instrumental to supporting team-based cancer care.

RESUMEN

Angiosarcomas (AS) are a diverse group of soft tissue sarcomas, arising from blood and lymphatic vessels. They frequently present in the elderly, and in patients with previous radiation or lymphedema. A wide range of genetic derangements contribute to their development, and AS histology is often high-grade in keeping with aggressive disease biology. The clinical presentation, while often innocuous, is marked by its infiltrative and aggressive nature, with a proclivity for metastatic spread, and outcomes are often poor. Surgery is performed for localized, resectable cases. A multidisciplinary approach, appropriately employing surgery, radiation, chemotherapy, or potentially recently approved immune-oncology agents, can result in positive outcomes.

RESUMEN

BACKGROUND: The etiology and pathophysiology of sarcoidosis remains unclear, with epidemiologic studies limited by its relatively low prevalence. The internet has prompted patients to seek information about medical diagnoses online; Google Trends provides access to an anonymized version of this data, which has a new role in epidemiology. We hypothesize that there is seasonal variation in the relative search interest of sarcoidosis, which would suggest seasonal variation in the incidence of sarcoidosis. METHODS: Google Trends was used to assess the relative search volume from 2010 to 2020 for "sarcoidosis" and "sarcoid" in 7 countries. ANOVA with multiple comparisons was performed to compare the mean relative search volume by month and by season for each country, with a p-value less than 0.05 indicating statistical significance. RESULTS: Our analysis revealed a significant seasonal variation in search popularity in 4 of the 7 countries and in the Northern Hemispheric countries combined. Direct comparison showed search terms to be more popular in spring, specifically March & April, than in the winter. Southern Hemisphere data was not statistically significant but showed a trend towards a nadir in December and a peak in September and October. CONCLUSIONS: Overall, these findings suggest seasonal variation with a possible peak in spring and nadir in winter. This supports the hypothesis that sarcoidosis has seasonal variation and is more commonly diagnosed in spring, but more evidence is needed to support this, as well as investigation into the pathophysiology of sarcoidosis to explain this phenomenon.

RESUMEN

PURPOSE: Although many studies clearly demonstrate disparities in cancer clinical trial enrollment, there is a lack of consensus on potential causes. Furthermore, virtually nothing is known about associations between patients' decision-making style and their participation in clinical trials. METHODS: Women with newly diagnosed, stage 0-II breast cancer reported to the Georgia and Los Angeles County Surveillance, Epidemiology, and End Results (SEER) registries in 2013-2014 were surveyed approximately seven months after diagnosis. We investigated two primary outcome variables: (1) invitation to participate in a clinical trial, (2) participation in a clinical trial. We evaluated bivariate associations using Chi-squared tests and used multivariable logistic regression models to investigate associations between patient variables, including decision-making style, and the primary outcomes. RESULTS: 2578 patients responded (71% response rate); 30% were > age 65, 18% were black, 18% were Latina, 29% had ≤ high school education. 10% of patients reported invitation to participate in a clinical trial; 5% reported participation in a clinical trial. After adjustment younger age, receipt of chemotherapy or radiation, disease stage, and a more rational (versus more intuitive) decision-making style were associated with a higher odds of invitation to participate. Being married was associated with a higher odds of participation; having an annual family income ≥ $40,000 was associated with a lower odds of participation. CONCLUSIONS: 10% of patients reported invitation to participate in a clinical trial, and half of these reported participation. Invitation to participate varied by age and decision-making style, and participation varied by marital status and income.

RESUMEN

BACKGROUND: Treatment of peripheral arterial disease (PAD) has become increasingly dominated by endovascular interventions. The short-term outcomes of endovascular therapy have been well studied, but late outcomes remain largely unpublished; in this series, we report the late outcomes of primary nitinol stenting. METHODS: All patients undergoing primary nitinol stenting of the superficial femoral artery (SFA) and/or popliteal artery (PA) during a 10-year period by a single surgeon (S.K.) were reviewed. No attempts were made on patients with orificial or total occlusion of the SFA, PA, and proximal tibial arteries. Differences in primary patency, primary-assisted patency, secondary patency, and freedom from bypass were evaluated at 1, 5, and 9 years. RESULTS: A total of 294 limbs in 240 patients were treated. One hundred and thirty additional endovascular procedures were observed during the study period averaging to 0.16 endovascular interventions per limb per year. Primary patency in TASC A/B limbs at 1, 5, and 9 years was 79%, 35%, and 19%, respectively, and in TASC C/D limbs was 62%, 11%, and 3%, respectively. Secondary patency in TASC A/B limbs at 1, 5, and 9 years was 96%, 81%, and 65%, respectively, and in TASC C/D limbs was 92%, 64%, and 41%, respectively. Freedom from bypass in TASC A/B limbs at 1, 5, and 9 years was 98%, 89%, and 85%, respectively, and in TASC C/D limbs was 95%, 78%, and 69%, respectively. Five below-the-knee amputations were observed during the study period. CONCLUSIONS: An endovascular-first approach can be applied to the vast majority of femoropopliteal lesions. While the late outcomes of TASC C/D lesions are inferior to those of TASC A/B lesions, an endovascular-first approach still provides durable outcomes.

RESUMEN

BACKGROUND: Patients with breast cancer involve multiple decision support persons (DSPs) in treatment decision making, yet little is known about DSP engagement in decision making and its association with patient appraisal of the decision process. METHODS: Patients newly diagnosed with breast cancer reported to Georgia and Los Angeles Surveillance, Epidemiology, and End Results registries in 2014-2015 were surveyed 7 months after their diagnosis. The individual most involved in each respondent's decision making (the key DSP) was surveyed. DSP engagement was measured across 3 domains: 1) informed about decisions, 2) involved in decisions, and 3) aware of patient preferences. Patient decision appraisal included subjective decision quality (SDQ) and deliberation. This study evaluated bivariate associations with chi-square tests between domains of DSP engagement and independent DSP variables. Analysis of variance and multivariable logistic regression were used to compare domains of DSP engagement with patient decision appraisal. RESULTS: In all, 2502 patients (68% response rate) and 1203 eligible DSPs (70% response rate) responded. Most DSPs were husbands/partners or daughters, were white, and were college graduates. Husbands/partners were more likely to be more informed, involved, and aware (all P values < .01). English- and Spanish-speaking Latinos had a higher extent of (P = .02) but lower satisfaction with involvement (P < .01). A highly informed DSP was associated with higher odds of patient-reported SDQ (odds ratio, 1.46; 95% confidence interval, 1.03-2.08; P = .03). A highly aware DSP was associated with higher odds of patient-reported deliberation (odds ratio, 1.83; 95% confidence interval, 1.36-2.47; P < .01). CONCLUSIONS: In this population-based study, informal DSPs were engaged with and positively contributed to patients' treatment decision making. To improve decision quality, future interventions should incorporate DSPs.

RESUMEN

BACKGROUND: Treatment decisions for patients with early-stage breast cancer often involve discussions with multiple oncology providers. However, the extent to which primary care providers (PCPs) are involved in initial treatment decisions remains unknown. METHODS: A stratified random sample of PCPs identified by newly diagnosed patients with early-stage breast cancer from the Georgia and Los Angeles Surveillance, Epidemiology, and End Results registries were surveyed (n = 517; a 61% response rate). PCPs were asked how frequently they discussed surgery, radiation, and chemotherapy options with patients; how comfortable they were with these discussions; whether they had the necessary knowledge to participate in decision making; and what their confidence was in their ability to help (on 5-item Likert-type scales). Multivariate logistic regression was used to identify PCP-reported attitudes associated with more PCP participation in each treatment decision. RESULTS: In this sample, 34% of PCPs reported that they discussed surgery, 23% discussed radiation, and 22% discussed chemotherapy options with their patients. Of those who reported more involvement in surgical decisions, 22% reported that they were not comfortable having a discussion, and 17% did not feel that they had the necessary knowledge to participate in treatment decision making. PCPs who positively appraised their ability to participate were more likely to participate in all 3 decisions (odds ratio [OR] for surgery, 6.01; 95% confidence interval [CI], 4.16-8.68; OR for radiation, 8.37; 95% CI, 5.16-13.58; OR for chemotherapy, 6.56; 95% CI, 4.23-10.17). CONCLUSIONS: A third of PCPs reported participating in breast cancer treatment decisions, yet gaps in their knowledge about decision making and in their confidence in their ability to help exist. Efforts to increase PCPs' knowledge about breast cancer treatment options may be warranted.

RESUMEN

PURPOSE: High costs of cancer care place considerable burden on patients and society. Despite increasing recognition that providers should play a role in reducing care costs, how physicians across cancer specialties differ in their cost-consciousness has not been reported. We examined cost-consciousness regarding breast cancer care among medical oncologists, surgeons, and radiation oncologists. METHODS: We identified 514 cancer surgeons, 504 medical oncologists, and 251 radiation oncologists by patient report through the iCanCare study. iCanCare identified newly diagnosed women with breast cancer through the Surveillance, Epidemiology, and End Results (SEER) registries of Georgia and Los Angeles. We queried providers on three dimensions of cost-consciousness: (1) perceived importance of cost saving for society, patients, practice, and payers; (2) awareness of patient out-of-pocket expenses; and (3) discussion of financial burden. RESULTS: We received responses from 376 surgeons (73%), 304 medical oncologists (60%), and 169 radiation oncologists (67%). Overall levels of cost-consciousness were moderate, with scores ranging from 2.5 to 3.0 out of 5. After adjusting for covariates, surgeons had the lowest scores on all three cost-consciousness measures; medical oncologists had the highest scores. Pairwise contrasts showed surgeons had significantly lower scores than medical oncologists for all three measures and significantly lower scores than radiation oncologists for two of the three cost-consciousness variables: importance of cost saving and discussion of financial burden. CONCLUSIONS: How cost-consciousness impacts medical decision-making across specialty and how policy, structural, and behavioral interventions might sensitize providers regarding cost-related matters merit further examination.
