The victim of a doctor whose schizophrenia saw him acquitted of sexually assaulting 17 of his patients has "given up faith in this country" after learning he was still practising.

Marlene Eziuzor, 51, broke down crying when she heard the Brisbane man was able to see patients again thanks to a tribunal decision.

In August 2012, Kevin Robert Wong was charged with 27 counts of sexual assault after police investigated allegations from 18 complainants - 17 patients and a female staff member.

The case was referred to the Mental Health Court in 2013, which found the doctor was suffering from "unsoundness of mind" during the alleged offences, acquitted him and allowed him to keep practising under a range of conditions including that he keep taking medication to ward off another relapse.
