This repository contains utilities for working with data. There are a mixture of 'helper' functions that relabel variables for you, or search for fields based on their metadata. And there are 'clinical' functions that derive secondary variables such as severity of illness scores (SOFA) etc.

Helper functions

• which_NHIC: Extract NHIC codes based on the value of a key:value pair in list
• find_NHIC: Look for possible matches in NHIC dict
• relabel_cols: Relabels a wide data2d data.table using the shortName field in the dictionary
• parse_ICNARC: Parses ICNARC diagnostic codes (Split text codes by level and then label as per ICNARC codes)

Clinical Utilities

• clean_gcs: Cleans GCS by replacing with NA where concurrently sedated
• gen_sofa_c: Generates the SOFA CVS score; requires MAP and norad and optionally handles other vasopressors
• gen_sofa_r: Generates the SOFA Respiratory score; requires PF ratio and optionally an indicator for postive pressure ventilation
• gen_sofa_k:
• gen_sofa_h:
• gen_sofa_n:
• gen_sofa_l:
