Abstract

PURPOSE:

To quantify the effects of opening a proton center (PC) on an academic medical center (AMC)/radiation oncology department.

METHODS AND MATERIALS:

Radiation treatment volume and relative value units from fiscal year 2015 (FY15) to FY17 were retrospectively analyzed at the AMC and 2 community-based centers. To quantify new patient referrals to the AMC, we reviewed the electronic medical record for all patients seen at the PC since consults were initiated in November 2015 (n = 1173). Patients were excluded if the date of entry into the AMC electronic medical record predated their PC consultation. Hospital resource use and professional and technical charges were obtained for these patients. Academic growth, philanthropy, and resident education were evaluated based on grant submissions, clinical trial enrollment, philanthropy, and pediatric case exposure, respectively, from PC opening through FY17.

RESULTS:

From FY15 to FY17, radiation fractions at the AMC and the 2 community sites decreased by 14% (95% confidence interval [CI], 12%-16%, P < .001) and increased by 19% (95% CI, 16%-23%, P < .001) and 2% (95% CI, -1.1 to 4.3%, P = NS), respectively; the number of new starts decreased by 3% (95% CI, -13% to 7%, P = NS) and 2% (95% CI, -20% to 16%, P = NS) and increased by 13% (95% CI -2% to 27%, P = NS), respectively. At the AMC, technical and professional relative value units decreased by 5% and 14%, respectively. The PC made 561 external referrals to the AMC, which resulted in $2.38 million technical and $2.13 million professional charges at the AMC. Fifteen grant submissions ($12.83 million) resulted in 6 awards ($3.26 million). Twenty-two clinical trials involving proton therapy were opened, on which a total of 5% (n = 54) of patients enrolled during calendar years 2017 and 2018. The PC was involved in gift donations of $1.6 million. There was a nonsignificant 37% increase in number of pediatric cases.

CONCLUSIONS:

Despite a slight decline in AMC photon patient volumes and relative value units, a positive downstream effect was associated with the addition of a PC, which benefited the AMC.
