Re-admission
The incidence of re-admission for pericardial effusion was 3.1% (n=12)
at a median of 11 days(IQR: 7.5-99). All the patients expect four
(NOACs=3, 27%; Warfarin=1, 9%), underwent surgical drainage. Four of
those patients were discharged on NOACs (Apixaban=2, 25%,
Rivaroxaban=2, 25%).
In the NOACs group the median effusion drained was 650mls (IQR:
525-775). In the Warfarin group, the median INR was 2.2 (IQR: 1.7-3.4).
Also, in this case, a higher INR was associated with a bigger effusion
(median:800mls, IQR: 750-1100), but this was not statistically
significant (r =0.8, R2=0.65 p =.192,
n=4).
