Scotland has some of the best health service data in the world. Few other countries have information which combines high quality data, consistency, national coverage and the ability to link data to allow patient based analysis and follow up. The Information Services Division (ISD) is a division of National Services Scotland, part of NHS Scotland. ISD provides health information, health intelligence, statistical services and advice that support the NHS in progressing quality improvement in health and care and facilitates robust planning and decision making.
This dataset provides four procedures (the main procedure code pair and three secondary procedure code pairs) may be recorded per hospital episode, using the Office for Population Censuses and Surveys Classification of Surgical Operation and Procedures (OPCS). A list of OPCS codes that make up the presented groupings can be found in the ‘Clinical Coding’ worksheet. ‘Other procedure codes’ relates to any other procedure codes not included in the previous groupings. Certain procedures (e.g. Joint aspiration, Bladder catheterization) may be an underestimate of the total number of procedures performed. This is due to a number of reasons including non-recording or under-recording in clinical summaries and incomplete coding. Also, there is currently no national data on procedures performed in Accident and Emergency (A&E) departments. The total number of colposcopies combines colposcopy of vagina and colposcopy of cervix.
Inpatient data derived from data collected on discharges from non-obstetric and non-psychiatric hospitals (SMR01) in Scotland. Only patients treated as inpatients or day cases are included. The specialty of geriatric long stay is excluded. Outpatient data are taken from the Scottish Morbidity Record 00 (SMR00) for outpatient attendances which collects patient-based data on new attendances at outpatient clinics in all specialties (except A&E and Genito-Urinary Medicine). In Scotland it should be noted that ‘Total knee replacement’ includes unicompartmental knee replacement.
Data completeness SMR01 returns are approximately 99% complete in NHS Scotland for financial year 2016-2017.
