Outcome Measures

Here is the list of the main outcome measures in QT:

PO1. PRE-OPERATIVE DIAGNOSIS - Positive or suspicious pre-operative cyto/histological diagnosis

Q.T. calculates the proportion of invasive or in situ operated patients who had had a positive or suspicious pre-operative cytological (C4, C5) or histological (B4, B5) diagnosis for cancer, out of the total number of invasive or in situ operated patients about whom we know whether they performed or not an FNA or a core biopsy or a tru-cut before the intervention.
Q.T. calculates separately the number of patients for whom it is not known whether they had a pre-operative diagnosis or which was this diagnosis.

Fields used: N00, I01,D08,D09

Eligible cases: (I01 IN (2,3,4)) AND (N00 IN (1,9) OR ISNULL(N00))

of which at denominator: DIAPRE IN (0,1,2,3,4,5)

of which at numerator: DIAPRE IN (4,5)

PO2. PRE-OPERATIVE DIAGNOSIS - Positive pre-operative cyto/histological diagnosis

Q.T. calculates the proportion of invasive or in situ operated patients who had had a positive pre-operative cytological (C5) or histological (B5) diagnosis for cancer, out of the total number of invasive or in situ operated patients about whom we know whether they performed or not an FNA or a core biopsy or a tru-cut before the intervention.
Q.T. calculates separately the number of patients for whom it is not known whether they had a pre-operative diagnosis or which was this diagnosis.

Fields used: N00, I01,D08,D09

Eligible cases: (I01 IN (2,3,4)) AND (N00 IN (1,9) OR ISNULL(N00))

11. Correct excision at 1st surgical biopsy

Q.T. calculates the proportion of patients with impalpable lesions (benign or malignant) which were correctly excised at the first surgical biopsy, out of the total number of patients operated on for impalpable lesions. Q.T. calculates separately: the number of patients with impalpable lesions for whom it is not known if they were excised correctly at the first surgical biopsy. It should be noted that the issue here is not the state of the margins but the fact that there was a failed biopsy (i.e. the mammogram following the biopsy shows the same lesion as was identified at the diagnostic mammogram). Consider that successive operations on the lesion may not be carried out in the department where the failed biopsy was carried out.
