Case study
Optimizing and orchestrating patient scheduling at the CHUM's integrated cancer center

The CHUM's clinical teams explain how GrayOS improved cancer care,

The problem
The Centre hospitalier de l'Université de Montréal (CHUM), a supra-regional hospital, is one of the largest providers in Canada and sees nearly 500,000 patients a year. The cancer center has 45 infusion chairs and 8 radiation treatment machines.

Like many cancer centers, the CHUM is facing major challenges:
- labor shortage

- growing treatments complexity,

- increasing patient volumes

- administrative burden

- inefficient coordination of care trajectories

- maxed out capacity and increasing patient delays
