Computer aided prescribing leaves holes in the safety net

that there were no technical set-up problems that could have accounted for the observed failures, we reported the problems that were identified to the manufacturers and invited comment.None of the systems produced alerts for all of the 18 scenarios (table).In terms of prescription of drugs with similar names, none of the systems warned for all 10 drug pairs considered.The evaluators produced no discrepancies in assessing the safety of systems.Each of the four system suppliers agreed with our assessments.We thank the PRIMIS staff for help with the system set up for the evaluation, GP computer system suppliers for responding constructively to our work, and Judy Cantrill and Caroline Morris for their involvement in the Delphi exercise.
