Grahame - can you elucidate on this? Are you saying that you have seen multiple parallel committers trying to update the same lab report (same patient, order etc) at the same time? The only way I can imagine this is if multiple specialist lab systems contribute to a common overall report (i.e. some kind of order grouping). In this case, there is unavoidably logic to do with how the pieces get stitched together anyway, so I am not sure how contention errors could arise. - thomas
