Cancer-related Emergency Department Visits: Comparing Characteristics and Outcomes

(2021)

Introduction: There is increasing appreciation of the challenges of providing safe and appropriate care to cancer patients in the emergency department (ED). Our goal here was to assess which patient characteristics are associated with more frequent ED revisits.

Methods: This was a retrospective cohort study of all ED visits in California during the 2016 calendar year using data from the California Office of Statewide Health Planning and Development. We defined revisits as a return visit to an ED within seven days of the index visit. For both index and return visits, we assessed various patient characteristics, including age, cancer type, medical comorbidities, and ED disposition.

Results: Among 12.9 million ED visits, we identified 73,465 adult cancer patients comprising 103,523 visits that met our inclusion criteria. Cancer patients had a 7-day revisit rate of 17.9% vs 13.2% for non-cancer patients. Cancer patients had a higher rate of admission upon 7-day revisit (36.7% vs 15.6%). Patients with cancers of the small intestine, stomach, and pancreas had the highest rate of 7-day revisits (22-24%). Cancer patients younger than 65 had a higher 7-day revisit rate than the elderly (20.0% vs 16.2%).

Conclusion: In a review of all cancer-related ED visits in the state of California, we found a variety of characteristics associated with a higher rate of 7-day ED revisits. Our goal in this study was to inform future research to identify interventions on the index visit that may improve patient outcomes.

Barriers and facilitators to telemedicine contraception among patients that speak Spanish: a qualitative study.

(2025)

BACKGROUND: Telemedicine contraception services have increased since the COVID-19 pandemic. There may be unique equity implications and language barriers for patients who speak Spanish. OBJECTIVE: To identify the barriers and facilitators of telemedicine for contraception care among patients who speak Spanish using a community-based participatory research approach. STUDY DESIGN: The study was designed and conducted in consultation with a community advisory board. We interviewed 20 patients after telemedicine and in-person contraception visits conducted in Spanish at Planned Parenthood of the Pacific Southwest in Southern California between April 2022 and May 2023. Telemedicine visits were conducted by audio only. Two coders analyzed the data using thematic analysis. RESULTS: The average age of the participants was 32.5 years old (range 19-45). Most participants had some college education (13/20, 65.0%) and public insurance (18/20, 90.0%). Most chose a short-acting contraceptive method (11/20, 55.0%). Five key themes were identified. (1) Participants reported less comfort with video technology and a preference to not be seen during the appointment, therefore preferring audio-only for telemedicine visits. (2) Participants did not report difficulty with Spanish interpreters using telemedicine. (3) Telemedicine has conveniences related to time, work, childcare, and transportation but may have inconveniences related to method receipt. (4) Preference for physical exam and preventative care and familiarity with the in-clinic model motivated people who sought in-person care rather than technology barriers with telemedicine. (5) There is trust in the privacy and confidentiality of the visits, but privacy at home for the individual may impact choice for in-person care. CONCLUSION: Among patients who speak Spanish, telemedicine contraception care was acceptable and had many conveniences. Many patients who speak Spanish preferred audio-only for telemedicine contraception visits. Use of interpreters and technology were not perceived barriers to care.

Guided Self-Help vs Group Treatment for Children With Obesity: A Randomized Clinical Trial.

(2025)

Background and objectives

Family-based behavioral treatment (FBT) for children with obesity is provided in weekly parent and child groups over 6 months. A guided self-help FBT program (gshFBT) is provided to the dyad in short meetings. Both interventions provide the same content; however, gshFBT provides this content in less time (FBT = 23 hours, gshFBT = 5.3 hours). This study aimed to evaluate whether gshFBT is noninferior to FBT on child weight loss and cost-effectiveness.

Methods

150 children aged between 7.0 and 12.9 years with a BMI between the 85th and 99.9th percentile and their parent were recruited and randomized to a 6-month program of gshFBT (n = 75) or FBT (n = 75) and were followed 12 months post-treatment.

Results

A total of 150 children (mean age = 10.1 years, 49% female, mean BMIz = 2.09) and their parent (mean age = 41.5 years, 87% female, 45% Hispanic, 37% White non-Hispanic, 9.7% Asian, 4.8% Black, 7.3% other) were recruited from the San Diego Metropolitan area. Joint LME models showed that gshFBT was noninferior to FBT on child weight loss (ΔBMIz = -0.02 [90% credible interval [CI] -0.08-0.05, P = .65]; ΔBMIp95% = -1.57 [90% CI -4.46-1.31, P = .28]) and cost less (cost/dyad gshFBT = $1498; FBT = $2775).

Conclusion

The gshFBT program provided similar weight losses for children with less contact hours and with lower cost than FBT. The reduced time and ease of scheduling for the family in gshFBT will allow for an increased reach of treatment to a greater proportion of families in need.

Characteristics and Outcomes of T1a Renal Cell Carcinoma Presenting with Metastasis.

(2025)

OBJECTIVES: The incidence of renal cell carcinoma (RCC) has been rising, largely due to increased incidental detection from widespread imaging. Although synchronous distant metastasis (SM) with a primary renal tumor measuring <4 cm (cT1a) is uncommon, its presence may influence survival outcomes and the utility of cytoreductive nephrectomy. We sought to investigate clinical characteristics, metastatic patterns, treatments, and survival outcomes of patients with T1a RCC. METHODS: All patients aged ≥18 years diagnosed with RCC between 2004 and 2019 were extracted from the National Cancer Database. The Cochran-Armitage test was used for trend analysis, while multivariable analyses were conducted to identify variables associated with SM and to assess the impact of cytoreductive surgery on mortality across isolated metastatic sites. Kaplan-Meier analysis was performed to compare survival outcomes. RESULTS: A total of 263,911 individuals diagnosed with T1a RCC were analyzed in the study. Among them, 114,661 patients (43.4%) were classified as having cT1a tumor stage, and of these patients with cT1a RCC, 2275 (2.0%) exhibited SM. The proportion of SM cT1a was 3.39% in 2004 and 2.08% in 2019, with an Average Annual Percent Change (AAPC) of -0.037% (p = 0.830). The most common sites of metastasis were bone (59%), followed by lung (35%), liver (16%), and brain (12%). Resection of the primary tumor and receipt of systemic therapy were significantly associated with reduced mortality among all metastatic sites, especially in individuals with lung-only metastases (HR = 0.02, p = 0.013). Metastasectomy was associated with improved survival in patients with brain-only metastases (HR = 0.26, p = 0.006) but did not demonstrate the same benefit in patients with bone-, lung- or liver-only metastases. The worst 5-year OS rate was observed in cases with metastasis to multiple sites, whereas isolated metastases had similar survival rates (p < 0.0001). Our findings are limited by retrospective study design. CONCLUSIONS: This comprehensive analysis of T1a RCC patients reveals that while synchronous metastasis is relatively uncommon (2.0%), it presents significant clinical challenges, with bone as the most common metastatic site, contrasting with the typical lung predominance in larger tumors. Primary tumor resection showed survival benefit in patients with isolated metastases, especially for lung-only metastasis. These findings highlight the heterogeneous nature of tumor biology in small renal masses and underscore the importance of tailored, multimodal treatment strategies for the effective management of SM T1a RCC.

Advanced Restriction Imaging and Reconstruction Technology for Prostate Magnetic Resonance Imaging (ART-Pro): A Study Protocol for a Multicenter, Multinational Trial Evaluating Biparametric Magnetic Resonance Imaging and Advanced, Quantitative Diffusion Magnetic Resonance Imaging for the Detection of Prostate Cancer.

(2025)

Multiparametric magnetic resonance imaging (mpMRI) is strongly recommended by current clinical guidelines for improved detection of clinically significant prostate cancer (csPCa). However, the major limitations are the need for intravenous (IV) contrast and dependence on reader expertise. Efforts to address these issues include use of biparametric magnetic resonance imaging (bpMRI) and advanced, quantitative magnetic resonance imaging (MRI) techniques. One such advanced technique is the Restriction Spectrum Imaging restriction score (RSIrs), an imaging biomarker that has been shown to improve quantitative accuracy of patient-level csPCa detection. Advanced Restriction imaging and reconstruction Technology for Prostate MRI (ART-Pro) is a multisite, multinational trial that aims to evaluate whether IV contrast can be avoided in the setting of standardized, state-of-the-art image acquisition, with or without addition of RSIrs. Additionally, RSIrs will be evaluated as a stand-alone, quantitative, objective biomarker. ART-Pro will be conducted in two stages and will include a total of 500 patients referred for multiparametric prostate MRI with a clinical suspicion of prostate cancer at the participating sites. ART-Pro-1 will evaluate bpMRI, mpMRI, and RSIrs on the accuracy of expert radiologists detection of csPCa and will evaluate RSIrs as a stand-alone, quantitative, objective biomarker. ART-Pro-2 will evaluate the same MRI techniques on the accuracy of nonexpert radiologists detection of csPCa, and findings will be evaluated against the expertly created dataset from ART-Pro-1. The primary endpoint is to evaluate whether bpMRI is noninferior to mpMRI among expert (ART-Pro-1) and nonexpert (ART-Pro-2) radiologists for the detection of grade group ≥2 csPCa. This trial is registered in the US National Library of Medicine Trial Registry (NCT number: NCT06579417) at ClinicalTrials.gov. Patient accrual at the first site (UC San Diego) began in December 2023. Initial results are anticipated by the end of 2026.

Personal legacy and treatment choices for serious illness: a scoping review.

(2024)

BACKGROUND: Legacy-how one hopes to be remembered after death-is an unexplored and important dimension of decision-making for people facing serious illness. OBJECTIVES: We conducted a scoping review to answer the following research questions: (1) How do people making treatment choices conceive of legacy? and (2) What treatment choices do people make with legacy in mind? ELIGIBILITY CRITERIA: Participants included people facing serious illness who discussed how they wanted to be remembered after their own death, or how they hoped to impact others, as they made treatment choices. Studies in English published between 1990 and 2022 were included. SOURCES OF EVIDENCE: We conducted searches in electronic databases including Medline/PubMed, CINAHL, PsycInfo, SocialWork, AnthropologyPlus, Web of Science, ProQuest and EMBASE databases. DATA SYNTHESIS: We used an electronic screening tool to screen abstracts and review full-text articles suitable for inclusion. We analysed included articles using Atlas.ti. We constructed tables and narratively synthesised the findings. RESULTS: We identified three major intersecting legacy goals that influence choices people facing serious illness make about their treatment and health behaviours, and the types of choices people make with legacy in mind. The three legacy goals are: remembrance of the individual self, remembrance of the social self and impact on others well-being. CONCLUSIONS: We identify the importance of legacy to patient treatment choices. Understanding for whom this construct is important, what types of legacy goals people hold and how those goals impact treatment choices is necessary to provide patient-centred whole-person care to people facing serious illness.

Social Risk Factors and Cancer Prevention Care among Patients in Community Health Care Settings.

(2024)

BACKGROUND: Social risks are negatively associated with receipt of cancer preventive care. As knowledge is lacking on the pathways underlying these associations, we investigated associations between patient-reported social risks and colorectal (CRC), cervical (CVC), and breast cancer (BC) screening order provision and screening completion. METHODS: This study included patients eligible for CRC, CVC, or BC screening at 186 community-based clinics between July 1, 2015 and February 29, 2020. Outcomes included: up-to-date status for indicated cancer screenings at baseline; percent of subsequent study months in which patients were up to date on screenings; screening order receipt; and screening completion. Independent variables were patient-reported food insecurity, transportation barriers, and housing instability. Analyses used covariate-adjusted generalized estimating equation models, stratified by social risk. RESULTS: Patients with documented social risks were less likely to be up-to-date on any cancer screening at baseline and in most cases had a lower rate of total study months up to date on screenings. All cancer screenings were ordered less often for food-insecure patients. CVC screening was ordered less often for transportation-insecure patients. The likelihood of completing a screening test differed significantly by select social risks: CVC and CRC screening rates were lower in food-insecure patients and CRC screening rates were lower in transportation-insecure patients. Likelihood of BC screening completion did not differ by social risk status. DISCUSSION: Social risks affect both the ordering and receipt of cancer screening. Research is needed on strategies to mitigate the impact of different social risks on cancer early detection services.

A policy toolkit for authorship and dissemination policies may benefit NIH research consortia.

(2024)

Authorship and dissemination policies vary across NIH research consortia. We aimed to describe elements of real-life policies in use by eligible U01 clinical research consortia. Principal investigators of eligible, active U01 clinical research projects identified in the NIH Research Portfolio Online Reporting Tools database shared relevant policies. The characteristics of key policy elements, determined a priori, were reviewed and quantified, when appropriate. Twenty one of 81 research projects met search criteria and provided policies. K elements (e.g., in quotations): manuscript proposals reviewed and approved by committee (90%); guidelines for acknowledgements (86%); writing team formation (71%); process for final manuscript review and approval (71%), responsibilities for lead author (67%), guidelines for other types of publications (67%); draft manuscript review and approval (62%); recommendation for number of members per consortium site (57%); and requirement to identify individual contributions in the manuscript (19%). Authorship/dissemination policies for large team science research projects are highly variable. Creation of an NIH policies repository and accompanying toolkit with model language and recommended key elements could improve comprehensiveness, ethical integrity, and efficiency in team science work while reducing burden and cost on newly funded consortia and directing time and resources to scientific endeavors.
