When a research group has multiple retracted publications and/or research misconduct by a member is evident, there is a risk that its other publications are unreliable, so a comprehensive assessment of the group's publications is advisable. We analyzed the comprehensiveness of assessment of the integrity of 300 publications by a research group with numerous retractions and known research misconduct, for 292 of which we raised concerns to publishers and academic institutions between 3/2013 and 2/2020. By 4/2023, 91 (30%) publications had not been assessed by either publisher or academic institution. Publishers had assessed 185 (63%) publications. The 4 academic institutions had assessed 5/36 (14%), 56/216 (26%), 30/50 (60%) and 40/66 (61%) publications. Unprompted assessments, those undertaken without our notification of concerns, occurred for 24 (8%) publications, 3 (1%) by publishers and 21 (7%) by academic institutions. Among 32 journals with ≥2 affected publications, no unprompted assessments of the remaining publication(s) occurred after notification of concerns about the index publication(s). Publishers retracted 58/84 (69%) publications which institutions also assessed and decided needed no editorial action. These analyses demonstrate the failure of publishers and institutions to comprehensively and spontaneously determine the integrity of publications in a setting of known misconduct and multiple retractions.
