These details include: staff name, client name, date and time of interview, client special needs.

Each client needs to book for each appointment beforehand by calling the CHS on 1800811811.

Details of all appointments made by all clients are stored in CHS database. These details are: appointment number, client number, data and time for which an appointment is booked, name of the staff who will see the client at the appointment.
