make_decisions: Human-friendly interface to the drug prep algorithm

In belayb/drugprepr: Prepare Electronic Prescription Record Data to Estimate Drug Exposure

Description

A helper function that allows specifying decision rules using English words rather than alphanumeric codes. Translates the rules into the corresponding codes and then passes them to drug_prep functions.

Usage

make_decisions(
  implausible_qty,
  missing_qty,
  implausible_ndd,
  missing_ndd,
  implausible_duration,
  calculate_duration,
  missing_duration,
  clash_start,
  overlapping,
  small_gaps
)

Arguments

implausible_qty	implausible total drug quantities
missing_qty	missing total drug quantities
implausible_ndd	implausible daily dosage
missing_ndd	missing daily dosage
implausible_duration	overly-long prescription durations
calculate_duration	formula or variable to compute prescription duration
missing_duration	missing prescription duration
clash_start	how to disambiguate prescriptions that start on the same date
overlapping	how to handle prescription periods that overlap with one another
small_gaps	how to handle short gaps between successive prescriptions The argument decision_phrases may contain the following terms (without brackets, separated with spaces). Additional or incorrectly-named elements will be ignored. implausible_qty (ignore|missing|mean|median|mode|next|previous) (individual|practice|population) implausible_ndd (ignore|missing|mean|median|mode|next|previous) (individual|practice|population) implausible_duration (ignore|missing|truncate) (6|12|24) missing_qty (ignore|mean|median|mode|next|previous) (individual|practice|population) missing_ndd (ignore|mean|median|mode|next|previous) (individual|practice|population) missing_duration (ignore|mean) (individual|population|both) calculate_duration (numdays|dose_duration|qty/ndd) clash_start (ignore|mean|shortest|longest|sum) overlapping (allow|shift) small_gaps (ignore|close) (15|30|60)

Value

A character vector suitable for passing to the decisions argument of the drug_prep function.

Examples

make_decisions('ignore',
               'mean population',
               'missing',
               'mean practice',
               'truncate 6',
               'qty / ndd',
               'mean individual',
               'mean',
               'allow',
               'close 15')
