English to Spanish Medical Medical: Health Care

Hi!
My sentence says:
Introducing and sustaining improvements to primary care’s gatekeeping role and attending to other aspects of the cancer care pathway might achieve greater gains and might be a better investment of resources than incentivization.

I see this definition for gatekeeping:
Primary care gatekeeping, in which the goal of the primary care physician (PCP) is to reduce patient referrals to specialists and thereby reduce costs, is not an adequate system in which to practice medicine.
