In 1989, Mustaffah was banned from using all
Ministry of Health facilities. According to
Nana Akuoko Sarpong, the then
Minister for Health, the
University of Ghana based on reports from agents of the Ministry of Health had laid serious charges of misconduct against him. It was alleged that Mustaffah had once prevented agents of the Ministry of Health from entering certain wards, "and had kept patients who are virtual vegetables on wards for 10-15 years when there is pressure on hospital space." These claims were strongly denied by Mustaffah. Dr. Fitz-Williams, a Soviet-trained cardiothoracic surgeon at the hospital at the time, described the allegations questioning the competence of Dr. Mustaffah as funny. Following these allegations and dismissal, the
Ghana Medical Association begun investigation into the matter. The then president of the association, Professor Harold H. Phillips claimed that the association was aware that three doctors (Dr. Mustaffah, Dr. Fitz-Williams, and Dr. Boakye-Danquah) had had problems with their employers (the ministry), however, no official complaint had been made to the association. Dr. Mustaffah in his defence claimed that he had only "objected to doctors doing rounds on his patients without his consent". On allegations of him using the CSR to forcibly dismiss his patients; he said he only had one patient with a spine problem who had been in the ward for 15 years due to inadequate rehabilitation facilities in the hospital. On the issue of insurance, he added that, he had engaged just one insurance company in America. A case which had been investigated by a government committee and a subsequent apology was issued to him following their findings. He added that it was not impossible for an incompetent person to run the neurological ward for over 20 years, and also serve as president of the Pan African Association of Neuro Surgergical Sciences. He described allegations of him practising occultism as nonsense. ==Personal life and death==
