Classcodes for adverse events after knee and hip arthroplasty

ICD-10 group names are prefixed by two letters as given by the references. Two groups (DB and DM) are split into two due to different conditions.

Usage

knee_ae

hip_ae

Format

Data frame with 3 columns:

group

Different types of adverse events (see reference section)

icd10

regular expressions identifying ICD-10 codes for each group

icd10_fracture

regular expressions for fracture patients. Essentially the same as regex but with some additional codes for group "DM1 other"

kva

regular expressions identifying KVA codes

condition

special conditions are used, see below.

An object of class classcodes (inherits from tbl_df, tbl, data.frame) with 7 rows and 5 columns.

Hip fractures

Adverse events (AE) codes for hip fractures are based on codes for elective cases but with some additional codes for DM 1 (N300, N308, N309 and N390).

Conditions

Special conditions apply to all categories. Those require non-standard modifications of the classcodes data prior to categorization.

hbdia1_hdia

TRUE if the code was given as any type of diagnose during hospital visit for index operation, or as main diagnose for later visits, otherwise FALSE

late_hdia

TRUE if the code was given as main diagnose at a later visit after the index operation, otherwise FALSE

post_op

TRUE if the code was given at a later visit after the index operation, otherwise FALSE
