aOnly those who requested the corresponding exam and reported a time in days between the time of request and the time of delivery of the exam were considered for the estimation of descriptive statistics (n: number of respondents responding; %: percentage of the total who were requested the exam) for all types of exams analyzed with P value < 0.001 of the Kolmogorov-Smirnov normality test and Lilliefors correction for the days between the time of request and delivery of the exams.
bPerceived delay: ranking generated based on the question “From the list of tests presented below, select the one you consider had the longest delay for delivery of results”.
Notes: 13.80% of the respondents were asked for only one exam, 6.46% for two, 7.22% for three, 70.35% for 4 to 8, and 12.17% for all exams.
Notes: Blood tests for tumoral markers (HER2, Ki67), PET, and CT of the abdomen and pelvis. Data was obtained from respondents who live or have lived the experience of having breast cancer in the Chilean healthcare system.
