The relevant investigations performed and their respective results, where present, e.g. endoscopy, CT Scan etc. It is important to highlight investigations and test results which relate to a GP action. (from A Clinician’s Guide to Record Standards – Part 2: Standards for the structure and content of medical records and communications when patients are admitted to hospital (Academy of Medical Royal Colleges, October 2008)) Investigations are procedures that are undertaken to find out more information about a patient’s state of health or wellbeing. [NPFIT-NCR-DES-0135.07 NHS Care Record Elements].
## Investigating Department ### Business Definition The clinical department responsible for the investigation. ### Requirement Reference Suggested by a member of the NHS CFH Pathology Programme team, accepted by the LRA Discharge Summary expert group 2011. ### Proposed Data Values A subset of the list of Specialty codes defined by the National Workforce Data set (NWD) v2.2 approved by the NHS Information Centre. ### Data Use Patient information, continuing care. ### Data Source Copied from previous record or new entry.
## Investigation Performed ### Business Definition A description of the investigation performed. Investigations are ‘a range of tests, measurements and procedures to obtain further information about an individual’s status’ (from Headings for Communicating Clinical Information from the Personal Health Record: A Position Paper, Crown Copyright June 1998).

The intent is to use codes wherever applicable (to allow automated record updates and analyses), but where authors want to add free text annotation, this should also be supported. Where no appropriate code exists, this value should be free text. (Note that free text data would not be accessible to automated interpretation). ### Data Use Patient information and continuing care. ### Data Source Copied from previous record entry. ### Data Examples - abdominal ultrasound - full blood count - mini mental state examination - ECT - gastroscopy - Waterlow Pressure Score ### Available Data Standards For laboratory investigations, NHS National Laboratory Medicine Catalogue (NLMC) Test Request Name or Test Request Display Name (associated with appropriate SNOMED CT concepts), LOINC or NPU. SNOMED CT concept expression for non-laboratory investigations (including the UK National Interim Clinical Imaging Procedure (NICIP) code set).
