To investigate the influence of implementing three-dimensional treatment pl
anning on staffing needs, valid questionnaire responses from 22 radiotherap
y institutions have been evaluated. Average time requirements per plan rise
from 213 to 439 min upon implementation, but with experience decrease to 3
17 min. No institution reports additional staff positions according to esti
mated requirements. (C) 1999 Elsevier Science Ireland Ltd. All rights reser
