August 2013 — TRF begins zoning of its hospice patients based in the eight barangays of Muntinlupa. The system allows for an organized and effective means to conduct regular visits to mapped out hospice patients. Specific nurses and days of the week are assigned to the different zones, with “Zone 4”, which covers referred patients not within Muntinlupa, being the exception. Any nurse may answer a referral from “Zone 4” depending on the location and urgency of the case.
