dx_self_report_lookup: Self-reported diagnosis lookup

In adamleejohnson/R-ukbiobank: UK Biobank Utilities

Self-reported diagnosis lookup

Description

Look up whether a diagnosis has been self-reported, based on coding 6. See https://biobank.ctsu.ox.ac.uk/crystal/coding.cgi?id=6. For disease-specific diagnosis_*() functions, the function dx_self_text_to_codes() is used internally to convert the text form of the diagnosis to the code used in the UKBdata table.

Usage

dx_self_report_lookup(
  data,
  codes,
  after_instance = default_after_inst(),
  up_to_instance = default_up_to_inst(),
  diagnosis_col = f.20002.0.0.Non_cancer_illness_code_self_reported
)

Arguments

data	The primarydata frame. Thisdata frame includes all necessary columns required to perform look-ups (e.g. ICD10 code columns, medication code columns, age, sex, etc.).
codes	Diagnosis codes to look up.
after_instance	An integer specifying an instance number, or the name of the column (using <data-masking> rules) containing instance numbers to use as the minimum instance (non-inclusive). Used to include alldata after but NOT including the specified instance number. Defaults to default_after_inst(), which is typically -1 (i.e., include instances 0 and later).
up_to_instance	An integer specifying an instance number, or the name of the column (using <data-masking> rules) containing instance numbers to use as the maximum instance (inclusive). Used to include alldata up to and including the specified instance number. Defaults to default_up_to_inst(), which as of this writing returns 3.
diagnosis_col	Template column name for self-reported diagnosis codes. Default = f.20002.0.0.Non_cancer_illness_code_self_reported.
