Information Flow and Coding:

What is coding?

Coding is the translation of clinical terminology into an (alpha) numeric code to make it easier to analyse data for management and epidemiological purposes. By supporting the process of collecting better quality information through accurate coding we contribute to the decisions that inform health care policy which ultimately leads to improvements in patient health.

For further information on coding please see Information Flow and Coding from Hospital Clinicians This file is available to download or view online Download PDF file [1.34mb].

Measuring Accuracy

DQA assess the quality of recording in a sample of records against source evidence in hospital systems and patient casenotes. Each data item is assessed and, if discrepancies in recording are identified, assigned an error type. More information on error types can be found - Error Type Definitions.

Data is analysed and results produced for reporting. ISD have a 90% standard for accuracy and recording of data.

Confidentiality

The “Confidentiality Rules for ISD Scotland Staff” are applied in the handling of all patient identifiable data. Supplementary to these rules, the team have their own procedures/rules designed to cover work in hospitals. In addition, the team will adhere to all hospital confidentiality procedures/rules.
