A doctor has been struck off the medical register for a year for professional misconduct. The Medical Council yesterday found Dr Lee York-fai guilty of two counts of professional misconduct for issuing two untrue and misleading certificates of attendance. The head of the disciplinary inquiry, Professor Felice Lieh Mak, said the council found that the certificates for Kan Che-ching on March 18 and 24 in 2004 were issued without proper clinical basis or without taking proper steps to verify the assessment. Kan, then 77, first attended Lee's clinic in September 2003, and has a history of diabetes and Parkinson's disease. She was admitted into St Teresa's Hospital for diabetes and a minor head injury in October 2003, but could still communicate effectively. Kan suffered a stroke in mid-December. Kan's daughter Connie Ip Chan Yuen-yee testified that her mother could no longer recognise her after the stroke. Ip wanted to put her mother under the government's guardianship. The Guardianship Board is authorised to appoint guardians for adults who are mentally incapable of making decisions. Three psychiatrists and one neurologist visited Kan after the stroke. However, because Kan's son did not want his mother to be under guardianship, he stopped the specialists' visits, meaning that their reports could not be submitted to the board. Lee, in his evidence, said he assessed Kan's cognitive ability in March by asking her a few questions. He estimated that she would score 25 out of 30. Based on these results and clinical observations of the patient over time, he issued certificates stating that the patient was 'alert, orientated to time, place and persons, and mentally sound and normal' on March 18, and was 'not a mentally incapacitated person' on March 24. But Lee admitted that the assessment was not conducted in a systematic manner. Lieh Mak concluded that Lee's clinical observations were inconsistent with the findings of the four specialists and one other general practitioner. 'We found the defendant doctor lacking in reliability,' she said.
