Are two sites better than one?: Sites of care and quality of myeloma treatment.

Abstract

e18159 Background: Care coordination affects the quality of cancer treatment. Multiple Myeloma (MM) patients frequently are cared for by local and referral center physicians. We sought to determine whether getting treated at different sites might impact on the quality of MM care. Methods: We used NCCN 2014 and CMS guidelines to define categories of treatment quality and transplant eligibility. We defined high quality MM care as: Induction for all patients with ECOG < 4; harvest & transplant for patients completing induction without progression, with albumin > 2.8, bilirubin < 3 and age ≤77 years; maintenance for transplant ineligible patients completing induction with no progression & for transplant eligible patients completing transplant with no progression; and supportive care of receiving bone targeting agents, anticoagulation and infection prophylaxis for all patients receiving MM therapy. Patients who received care with both local and referral center physicians were considered to have received care at 2 sites. We abstracted 709 charts of patients with ICD-9 diagnosis of MM from 2010-2014 for demographics, site of care and treatments received. We compared groups with chi square and multivariate logistic regression models with age, insurance, race, comorbidity and sites of care to predict care quality. Results: Of the 709, 388 had active MM. On average, patients were 62 ±11 years. Overall, 70% received care at > 1 site. Referred patients had no differences by age, comorbidity index, insurance or race. Having > 1 care site was associated with higher rates of induction and harvest. Conclusions: Historically, hand-offs in care have been associated with poorer quality. However, in a referral center, hand-offs do not negatively affect induction and harvest care quality. Patients referred to a MM center are more likely to get high quality treatments for which they are referred, but referral does not ensure receiving the full gamut of needed MM treatments.[Table: see text]
