Patients who received conventional treatment were compared to those treated with ATC and portable digital drainage. Propensity weighting, including comorbidities, medication and perioperative characteristics, was applied for outcome assessment.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>RESULTS<\/jats:title>\n                    <jats:p>In propensity-adjusted patients, 14.6% of conventional patients had interventions for RBS, with 4.1% underdoing early re-exploration for bleeding. In the ATC group, 6.9% required interventions for RBS [odds ratio (OR) 0.43, P\u2009&amp;lt;\u20090.001] with a 3.7% re-exploration rate. Patients in the portable digital drainage group had RBS in 5.1% (OR 0.31, P\u2009&amp;lt;\u20090.001) with a 1.2% rate of re-exploration (OR 0.29, P\u2009&amp;lt;\u20090.001). Postoperative AF dropped by 37% from 29.8% in the conventional to 18.7% in the portable digital drainage cohort (OR 0.31, P\u2009&amp;lt;\u20090.001). In-hospital mortality was similar with 1.6% (6 of 369) in the conventional versus 1.1% (2 of 188) in the ATC versus 0.8% (4 of 492) in the portable digital drainage cohort (P\u2009=\u20090.358).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>CONCLUSIONS<\/jats:title>\n                    <jats:p>Active tube clearance and portable digital drainage cohorts had fewer RBS interventions. In addition, portable digital drainage was associated with reduced early re-exploration for bleeding and lower postoperative AF.
