During my tenure at Sheffield Teaching Hospitals, I approached data analysis by implementing a structured method to identify discrepancies. The process began with cross-referencing data from multiple systems, such as the hospital's internal system and the national database. This allowed me to spot inconsistencies in patient records. When discrepancies were found, I first verified the accuracy of our internal data. If our data was correct, I escalated the issue to the relevant department to address any errors in the national database. Conversely, if the issue was within our system, I worked closely with the IT team to update and correct the data. This collaborative approach ensured data integrity and helped maintain accurate patient records.
