  "abstract": "Introduction Dedicated endoscopic surveillance (DS) for Barrett’s oesophagus (BO) is likely to be more effective than non-dedicated service (NS).Methods A multicentre retrospective cohort study conducted across 6 UK hospitals comparing DS vs NS by means of key performance indicators (KPI) and dysplasia detection rates (DDR). Logistic regression was used to assess the factors associated with DDR.Results Data from 1037 DS and 976 NS procedures (N=2013, by 180 endoscopists) were included. M:F=2.3:1.0, mean age - 64.4(SD±12.2) years. Mean maximum length of BO - 4.1cm (SD±3.1).Lesions detection was significantly associated with DDR (OR-6.9), while Seattle protocol adherence showed a negative correlation (OR–0.47). Number needed to scope in NS (37.5), is 2.5 times higher for dysplasia detection than in DS (14.8).A health improvement project (HIP) was initiated recruiting 20 endoscopists to undergo a structured training program to improve their surveillance skills to DS standards.Conclusion DS has high quality and higher dysplasia detection with lower complication rate. Lesion recognition but not Seattle adherence, was associated with increased DDR.Abstract O74 Table 1KPIDS (%)NS (%)PHiatus hernia delineation 746(72.1)289(27.9)<.001Prague classification1004(96.8)868(89.0)<.001Island identification 200(19.3)53(5.4)<.001Lesions detection 227(21.9)61(6.3)<.001Paris classification 63(6.4)5(0.5)<.001Seatle Biopsy protocol adherence959(92.6)747(76.6)<.001Targeted biopsy acquisition 249(24.0)787(76.0)<.001Barrett’s Inspection time 395(38.1)7(0.7)<.001OtherUse of sedation522(51.2)501(48.9)0.019Narrow band imaging use 938(90.7)325(33.3)<.001Acetic acid chromoendoscopy use 674(65.1)44(4.5)<.001DDR70(6.9)26(2.8)<.001Complications3(0.3)11(1.1)0.046",
