The development of a provincial radiation oncology service: the first year report and its implications for future developments.
This study compares the actual first year's workload of a new radiation oncology department with that predicted, and assesses the impact of the differences, and their implications for future similar developments. The treatment records and diaries for the Geelong Hospital Radiation Oncology Department were reviewed after the first 12 months of operation (opened in June 1992). Statistics relating to the number of patients seen, number treated, diagnosis, etc., were evaluated and compared to the original estimates based upon population statistics and likely referral rates. Nine hundred and seven new patients were seen in this period, and from them 718 courses of treatment were initiated. One hundred and eighty-nine cases (20% of referrals) were seen but not treated. A further 102 treatment courses (14% of total) were initiated upon patients who had previously been irradiated. Forty-six per cent of patients were managed by 10 fractions or fewer, and a further 23% by 25 or more fractions. Eighty per cent of patients were managed by one or two fields. Electrons were used in only 14% of cases. Further calculations suggested a further possible 441 cases of referral could be expected, based upon current population statistics. Referral rates for radiation oncology are highly dependent on a number of factors. As a result, estimates of referrals and hence the size of a department required for a given population vary widely. Our data support these concepts, and the concept that referral is also strongly dependent upon the distance patients need to travel. In considering the development of units outside of major cities it is suggested that referrals are likely to be on the high side of estimates and a minimum two-machine unit is essential to cover the given workload.
