TISS implies dx

Any ICU patient with LOS>3 and (T33/34/35) in TISS28 who doesn't have one of dxs (350, 351, 352, 355, 356, 398, 450-499, 327, 357) is an error.

Reality check

Short stay patients, incl community hospitals

CRF/ARF patients may not receive dialysis if they are only there for a short time. That led to false=positives for the check, especially in community hospitals, so the restriction of "LOS>3" was added.
