What is PEDW?
The Patient Episode Database for Wales (PEDW) was implemented in April 1991. The database contains all inpatient and day case activity undertaken in NHS Wales plus data on Welsh residents treated in English Trusts. In 1997 the mandated inpatient and day case dataset changed to Admitted Patient Care (APC). The decision to adopt APC was to align the Welsh inpatient and day case dataset with England to allow benchmarking. Some data items previously submitted on PEDW were dropped and new date items added to the APC format. APC contains demographic, clinical and administrative detail, such as age and sex of patient; diagnostic and operative procedures (ICD10 and OPCS -4). There are approximately 100,000 episodes of care processed per month.
The Data Acquisition Team are responsible for the collection, processing and monitoring of the monthly Admitted Patient Care extracts received from Welsh NHS sites that provide inpatient and day case care and English sites that treat Welsh residents. These extracts are used to update the Patient Episode Database for Wales (PEDW), from which the Business Intelligence Team provide an analysis service and extract data which are used for Welsh Government Publications.
APC extracts are received on a monthly basis directly from Welsh NHS sites and a download from SUS for Welsh residents treated in English hospitals. The submission date is the 17th day of each month. A report is produced each month, which monitors the timeliness of data submissions.
