We invite you to rate your experience with us
After receiving a service at COA facilities, a short opinion survey will be sent to you. Remember to provide your email address at the admissions areas to ensure your contact informations is up to date.

The patient-centered experience methodology applied at COA is called NPS-Net Promoter Score. The approach consists of asking about the likelihood of recommending the service provided to someone they know. Patient loyalty is measured on a scale from 0 to 10. Depending on the score given by the patient, they will be categorized one of the following groups:
Promoters
They score 9 or 10; they represent the most loyal and satisfied patients.
Passives
They score 7 or 8; neutral patients, meaning they are not actively recommending COA
Detractors
They score between 0 and 6; dissatisfied patients who will actively not recommend the service
