Patterns of multidisciplinary care in the management of non-metastatic invasive breast cancer in the United States Medicare patient.

ABSTRACT: Multidisciplinary care (MDC) in managing breast cancer is resource-intensive and growing in prevalence anecdotally, although care patterns are poorly characterized. We sought to determine MDC patterns and effects on care in the United States Medicare patient.Patients diagnosed with non-metastatic invasive breast cancer from 1992-2009 were reviewed using the Survival, Epidemiology, and End Results (SEER)-Medicare linked dataset. MDC was defined as a post-diagnosis, preoperative visit with a surgical, medical, and radiation oncologist. Same-day MDC (MDCSD) was the MDC subset having all three visits on one date.Among 88,865 patients, MDC was utilized in 2.9 %, with 14.1 % of these having MDCSD. MDC use did not vary by stage, but MDC patients were more likely to be younger, black, receive lumpectomy, have fewer nodes examined, and receive radiotherapy. MDCSD patients were more likely than non-MDC patients to be black, receive mastectomy, and receive radiotherapy. MDC and MDCSD use increased over time and varied by geographic region, with rural patients less likely to receive MDC (OR 0.54 [95 % CI 0.45-0.65]) and MDCSD (OR 0.32 [95 % CI 0.19-0.54]). Radiotherapy after breast conserving surgery, used in 86.2 % of non-MDC patients, was administered to 90.2 % of MDC (p < 0.001) and 92.6 % of MDC(SD) (p = 0.096) patients. Post-mastectomy radiotherapy was administered in 52.0 % of non-MDC patients, 63.8 % of MDC (p = 0.050), and 89.1 % of MDC(SD) (p = 0.011) patients after propensity score adjustment.While increasing, few Medicare patients undergo MDC and MDCSD is rare. MDC may improve quality and MDCSD should be considered for patient convenience. While not yet widespread, efforts should integrate MDC and MDCSD across the U.S.

Project description:ImportanceMultidisciplinary care (MDC) yields proven benefits for patients with cancer, although it may be underused in the complex management of head and neck squamous cell carcinoma (HNSCC).ObjectiveTo characterize the patterns of MDC in the treatment of HNSCC among elderly patients in the US.Design, setting, and participantsThis nationwide, population-based, retrospective cohort study used Surveillance, Epidemiology, and End Results (SEER)-Medicare linked data from January 1, 1991, to December 31, 2011, to identify patients 66 years or older diagnosed with head and neck cancer and determine the dates of diagnosis, oncology consultations, treatment initiation, and speech therapy evaluation in addition to MDC completion. Multidisciplinary care was defined in a stage-dependent manner: localized disease necessitated consultations with radiation and surgical oncologists, and advanced-stage disease also included a medical oncology consultation, all before definitive treatment. Data were analyzed between December 2016 and September 2020.Main outcomes and measuresRates of MDC across all subsites of head and neck cancer as measured by the presence of an evaluation for each oncologist on the MDC team and its effect on treatment initiation.ResultsThis cohort study assessed 28 293 patients with HNSCC (mean [SD] age, 75.1 [6.6] years; 67% male; 87% White) from the SEER-Medicare linked database. The HNSCC subsites included larynx (40%), oral cavity (30%), oropharynx (21%), hypopharynx (7%), and nasopharynx (2%). Overall, the practice of MDC significantly increased over time, from 24% in 1991 to 52% in 2011 (P < .001). For patients with localized (stage 0-II) tumors, 60% received care in the multidisciplinary setting, whereas 28% of those with advanced-stage disease did. A total of 18 181 patients (64%) were treated with initial definitive nonsurgical therapy across all stages. Regardless of stage and subsite, few patients (2%) underwent evaluation by a speech-language pathologist before definitive therapy. Multidisciplinary care prolonged the time to initiation of definitive treatment by 11 days for localized disease and 10 days for advanced disease.Conclusions and relevanceThis cohort study found that most elderly patients with localized HNSCC received MDC, whereas few patients with advanced-stage disease received such care, although a significant proportion received adjuvant therapy. Multidisciplinary care may prolong time to initiation of definitive treatment with an uncertain impact. Consultation with a speech-language pathologist before definitive therapy was rare.
