OPCS labels for procedure items in NELA dataset

There are over 400 OPCS codes that might be used to code patients undergoing emergency laparotomy. The codes in the form below should allow people to identify potential procedures within NELA, but hospitals will need to filter out those procedures that do not meet the NELA inclusion criteria.

We do not recommend that hospitals use OPCS codes as the sole mechanism to identify patients for inclusion into NELA. The inclusion/exclusion criteria are defined according to clinical definitions, not coding definitions. For this reason, it will be extremely difficult for hospitals to provide accurate audit data using OPCS codes to retrospectively identify patients.

The audit is intended to be completed by clinical teams as the patient progresses through the emergency laparotomy pathway. The data entry tool has been designed to facilitate this as much as possible.
