HEALTH Department chief Margaret Chan Fung Fu-chun promised yesterday to improve staffing levels in evening clinics after admitting there was no one to keep individual records of patients at night. The problem came to light after the department failed to contact at least one night-time patient among 35 patients who were given cough syrup mixed with the wrong type of chloroform at a government clinic in February and March. 'We will hire more clerks during night shifts to take individual records of patients,' Dr Chan said during a radio interview. 'It's not that we don't have the money, but we have been having difficulties finding people willing to work only four hours at night.' The department operates 63 daytime clinics and 21 evening clinics. Unlike patients treated during office hours, individual medical records of those who visit between 6pm and 10pm are not kept. 'We aim to keep personal particulars as well as individual medical history. Unfortunately, sometimes the patients themselves are reluctant to give their addresses and phone numbers for future contact.' The department did not disclose how many clerks would have to be hired to attain adequate staffing levels. Democratic Party legislator Michael Ho Mun-ka said he would follow up the issue at the Legco health panel, of which he was the chairman. 'You can't hire people at night? You have got to be kidding!' he said. 'Maybe, they mean they haven't tried.' Dr Chan told people to take care of their health on the anniversary of the bird flu crisis, as the high flu season of February and March was fast approaching. She said there was no evidence yet that a flu breakout on the mainland had reached Hong Kong.
