Health authorities on Friday said an oversubscription arrangement for online public dental bookings and a waiting-list mechanism will be introduced next week in a bid to prevent no-shows. The Department of Health earlier launched its online registration for public dental services in a bid to avoid residents queuing overnight, but some people failed to show up for the appointments. "Upon initial enquiry, they said that they were unable to attend due to other commitments or had forgotten their appointment, while others said that they were unaware that the scope of the service was limited to emergency dental services," a department spokesperson said. From January 6, public dental clinics will "suitably increase the number of successful applicants to a level exceeding the actual service quotas", and introduce a waiting list to fill possible vacancies. People who register successfully will be asked to confirm their attendance. If they are not able to do this, the slot will be assigned to someone on the waiting list. Those aged 65 or above who have registered but failed to secure a spot will be given priority on the waiting list. Authorities also said people allocated a spot must arrive at designated dental clinics by 8.30am on the day of the appointment. Staff members will begin reaching out to people on the waiting list to fill vacancies from 9.30am. "Depending on the absence rate at each clinic, the [Department of Health] will suitably increase the quota of successful applicants and set up a waiting list to fill vacancies without compromising the overall quality of service, which remains the top priority," the spokesperson said. "The [Department of Health] will continue to monitor the operation of the new system and keep in view the utilisation and attendance rates. If the situation warrants, a mechanism to deter absenteeism and abuse may be introduced."
