Diagnostic Intervals.
The average diagnostic interval was 9.3 weeks (median 3.5 weeks), and the mean patient interval is 6.1 weeks (median 0.6 weeks.) The following results compare TDIs, PIs and SIs in relation to tumour type and location as well as age group, patient location and distance between home and hospital.
Tumour type, Low grade tumors had the longest TDI of 6.6 weeks followed by Medulloblastomas (4.6 weeks) and High-grade gliomas (3.3 weeks)(Supplemental File 1.) There is a relatively equal distribution of PI between different tumour types, with Ependymomas and High-grade gliomas having the longest PI of 0.6 weeks, Medulloblastomas with 0.5 weeks and Low-grade gliomas with the PI of 0.4 weeks. Alternatively, Low grade gliomas and Medulloblastomas had the longest SI of 0.9 weeks, followed by Ependymomas and High-grade gliomas which had the lowest SI of 0.3 weeks.
