Calculating the GP consultation fee in Singapore: towards a rational costing approach

The General Practitioner (GP) consultation fee in Singapore, unlike that of his specialist colleague, has been left very much undefined over the years. There is a need for an objective way of calculating the GP consultation fee.

A proposed method of calculating the GP consultation fee based on the model of estimating the total cost of producing the service plus the doctor's remuneration is described. Known prevailing costs were used in the computation. This model allows us to work out the cost to the patient by dividing the total cost of producing the service by the number of patients (referred to as patient encounter load) seen by each duration of consultation--4, 6, 10, 15 and 30 minutes. Different monthly remuneration levels for the doctor were used to compute the different consultation fees that would result for each of the duration of consultations.

Using this method of calculation, for a doctor with a desired monthly remuneration of $7000, and seeing a patient every 6 minutes over a 150-hour month, the consultation fee is $13.00. This drops to $11.00 if the doctor receives a remuneration of $4000 per month. Using the same parameters, a 15 minute consultation will cost the patient $30.00 and $25.00 respectively.

This method can be used to derive a consultation fee for services requiring different durations and varying remuneration brackets for the doctor.
