Study success criteria were attrition not >50%, <10% long‐term abdominal drain removal due to complications, the long‐term abdominal drain group to spend <50% ascites‐related study time in hospital vs large‐volume paracentesis group and 80% questionnaire/interview uptake/completion.</jats:p></jats:sec><jats:sec><jats:title>Results</jats:title><jats:p>Of 59 eligible patients, 36 (61%) were randomised, 17 to long‐term abdominal drain and 19 to large‐volume paracentesis. Following randomisation, median number (IQR) of hospital ascitic drains (long‐term abdominal drain group vs large‐volume paracentesis group) were 0 (0‐1) vs 4 (3‐7); week 12 serum albumin (g/L) and serum creatinine (μmol/L) were 29 (26.5‐32.5) vs 30 (25‐35) and 104.5 (81‐115.5) vs 127 (63‐158) respectively. Total attrition was 42% (long‐term abdominal drain group 47%, large‐volume paracentesis group 37%). Median (IQR) fortnightly community/hospital/social care ascites‐related costs and percentage study time in hospital were lower in the long‐term abdominal drain group, £329 (253‐580) vs £843 (603‐1060) and 0% (0‐0.74) vs 2.75% (2.35‐3.84) respectively. Self‐limiting cellulitis/leakage occurred in 41% (7/17) in the long‐term abdominal drain group vs 11% (2/19) in the large‐volume paracentesis group; peritonitis incidence was 6% (1/17) vs 11% (2/19) respectively. Questionnaires/interview uptake/completion were ≥80%; interviews indicated that long‐term abdominal drains could transform the care pathway.</jats:p></jats:sec><jats:sec><jats:title>Conclusions</jats:title><jats:p>The REDUCe study demonstrates feasibility with preliminary evidence of long‐term abdominal drain acceptability/effectiveness/safety and reduction in health resource utilisation.</jats:p><jats:p>Trial registration: ISRCTN30697116, date assigned: 07/10/2015.</jats:p></jats:sec>
