A total of 139 adverse events were recorded in 75 patients (56%). A total of 59 additional surgeries were needed in 39 patients. A significant difference was seen in the rates of adverse events recorded between 2007–2010 and 2011–2014 (60.7% vs 42.6%, p=0.002). A significant reduction in ONS revision was seen over time (25.7% vs 5.9%, p=0.002). Analysis of adverse events with IPG site showed those with abdominal implants recorded higher adverse event rate that those with an IPG in the chest (65.8% vs 40.3%, p=0.004).</jats:p></jats:sec><jats:sec><jats:title>Conclusions</jats:title><jats:p>In specialist centres, adverse event rates of ONS can be much lower than reported in the literature. Our results suggest implanter experience and IPG site both have an effect on adverse event rate.</jats:p></jats:sec> 3 [] ["S Miller", "L Watkins", "M Matharu"] [""] [""] [""]
