Check for COVID-19 AE with DRUG WITHDRAWN action without "ADVERSE EVENT" for DS Trt Discon

Description

This checks for a COVID-19 AE reported with Action Taken (AEACN*==DRUG WITHDRAWN) but without a corresponding DS record indicating DS.DSDECOD with "ADVERSE EVENT" on any Treatment Discontinuation form. This relies on DSSPID with the string "DISCTX" when DSCAT == "DISPOSITION EVENT" to select Treatment Discontinuation records in DS, as DSSCAT typically includes a text string referring to specific study drug(s).

Usage

check_ae_aeacn_ds_disctx_covid(
  AE,
  DS,
  covid_terms = c("COVID-19", "CORONAVIRUS POSITIVE")
)

Arguments

AE

Adverse Events SDTM dataset with variables USUBJID, AETERM, AEDECOD, AESTDTC, AEACNx
DS

Disposition SDTM dataset with variables USUBJID, DSSPID, DSCAT, DSDECOD
covid_terms

A length >=1 vector of AE terms identifying COVID-19 (case does not matter)

Value

boolean value if check returns 0 obs, otherwise return subset dataframe.

check_ae_dup(AE)

Check for death variable consistency when AEOUT=="FATAL"

Description

This check looks for consistency in AESDTH, AEDTHDTC, and AETOXGR (if applicable) when AEOUT is 'FATAL'. Note, this check expects AE grade/severity variables to be populated for either all records or none. In a case where both AETOXGR and AESEV exist and some records are supposed to have AETOXGR populated while others have AESEV (ie the two variables are mutually exclusive) then this check will likely return false positives.

Description

This check looks for patients in DS who have a record indicating death but no corresponding record with death date in DS.

Check if 1m BCVA test stops too late, too early and has correct total

Description

This ophthalmology check is for BCVA 1m test. It checks three conditions: <1> BCVA test stops too late, meaning that lines were read after number of correct letters is <= 3. <2> BCVA test stops too early, meaning that further lines were not read when all numbers of correct letters is > 3. <3> BCVA total score is not correct, meaning that the sum of the number of correct at 1 meter doesn't match with what has been recorded in eCRF (BCVA Scores eCRF Page - C. Total number correct at 1m). Please note that this check only works with USUBJID, VISIT, VISITNUM, OELOC, OELAT combination has unique dates (OEDTC). If your datasets are having situations like 1) unscheduled visits happening on different dates or 2) BCVA TOTAL happens on a different date from BCVA row tests, such combinations will be removed from check. Please note that this check excludes forms BCVA Low Vision Test (BCV5), BCVA Scores (BCV7), BCVA Low Luminance Scores (BCVLL5), BCVA Combined Assessments (BCVAC), BCVA Low Luminance Combined Assessments (BCVACLL) before running check as these forms do not include Row numbers.

Check if 1m BCVA test is completed per BCVA 4m result

Description

This ophthalmology function is to check if BCVA 1m test is done per BCVA 4m result. Patient, Visits, Laterality where Low Vision Tests were done are excluded from this check. 1> If 4m test total <= 19 and 1m test is not done. 2> If 4m test total >= 20 and 1m test is performed Above two conditions will be outputted in the final result data frame, which includes USUBJID, VISIT, OEDTC, OELAT, BCVA_4M_TOTAL, BCVA_1M_TOTAL, ISSUE. Please note that this check will assume that the BCVA 1m and 4m total are accurate and they happen on the same day. If they are happening on different dates, such records will be removed and not checked.

Usage

check_oe_bcva_4m_vs_1m_req(OE)

Arguments

OE

Ophtho Dataset with variables USUBJID, OECAT, OESCAT, OETSTDTL, OESTRESN, OESTAT, OELAT, OERESCAT, VISIT, OEDTC, OEDY

Value

boolean value if check failed or passed with 'msg' attribute if the test failed

Check to confirm that there is a reason for a questionnaire being marked as not done

Description

This code flags when QSSTAT Completion Status is marked as NOT DONE but QSREASND Reason Not Performed is not populated. Some but not all questionnaires in a study may collect Reason Not Performed information, so there may be instances of false positives in which no data correction is required. While QSREASND is a permissible variable, this scenario will be flagged in P21.

Usage

check_qs_qsstat_qsreasnd(QS)

Arguments

QS

Questionnaire SDTMv dataset with USUBJID, QSCAT, QSDTC, QSSTAT, QSREASND, VISIT (optional) variables

Value

boolean value if check returns 0 obs, otherwise return subset dataframe.

Check for consistency between new lesions and overall PD response

Description

This checks for patients with new lesions in TU (TUSTRESC=='NEW') but no Overall Response assessment of PD (Disease Progression) or PMD (Progressive Metabolic Disease) in RS (i.e., (RSTESTCD=='OVRLRESP' and RSSTRESC %in% c('PD','PMD'))). Only applies to assessments by investigator, if TUEVAL and RSEVAL variables available.

Usage

check_tu_rs_new_lesions(RS, TU)

Arguments

Response SDTM dataset with variables USUBJID, RSSTRESC, RSTESTCD
TU

Create a sdtmchecks list object with column indicating whether the issue was previously seen

Description

This report will identify flagged records from an sdtmchecks report that are "new" and those that are "old" for a study. This will help quickly target newly emergent issues that may require a new query or investigation while indicating issues that were encountered from a prior report and may have already been queried.

This diff_reports() function requires a newer and older set of results from sdtmchecks::run_all_checks(), which will generate a list of check results. An added column "Status" is created with values of "NEW" and "OLD" in the list of check results, flagging whether a given record that is present in the new result (ie new_report) is also present in the old result (ie old_report). It makes a difference which report is defined as "new" and "old". This code only keeps results flagged in the new report and drops old results not in the new report because they were presumably resolved.

Usage

diff_reports(old_report, new_report)

Arguments

old_report

an older sdtmchecks list object as created by run_all_checks
new_report

a newer sdtmchecks list object as created by run_all_checks

Value

list of sdtmchecks results based on new_report with Status indicator

Run all data checks in sdtmchecks package using parallel processing

Description

This function runs all checks in the sdtmchecks package. It expects SDTM domains saved as dataframe objects in your global environment. These dataframes should have lowercase names, e.g., dm.

Usage

run_all_checks(
  metads = sdtmchecksmeta,
  priority = c("High", "Medium", "Low"),
  type = c("ALL", "ONC", "COVID", "PRO", "OPHTH"),
  verbose = TRUE,
  ncores = 1
)

Arguments

metads

Metadata to use to execute the checks. The default is the sdtmchecksmeta dataframe available in the package. This object could easily be customized, subset, etc.
priority

Priority level of data checks, i.e., c("High", "Medium", "Low"). NULL runs all priority levels.
type

Type of data checks, i.e., c("ALL", "ONC", "COV", "PRO", "OPHTH"). NULL runs all type.
verbose

Whether to display messages while running
ncores

Number of cores for parallel processing, with default set to 1 (sequential)

Details

To look up documentation for the data checks in package, please use command ??sdtmchecks

Value

list with results from individual data check functions

See Also

Example programs for running data checks diff_reports(), report_to_xlsx(), run_check()

Examples

# Assuming sdtm datasets are in your global environment
# Note we are only specifying AE and DS here so all unrelated checks wont be run

Run a single check in sdtmchecks package

Description

This function runs a single check in the sdtmchecks package. It expects a check name, the function that performs the check and some info for the pdf and Excel files. It also expects a T/F value that determines whether to display messages while running. Excluding verbose, the parameters for this function are usually passed to it by filtering the metads to only contain the row corresponding to the check of interest, and then assigning each parameter as the contents of the eponymous column of metads (see example below). This is because this function is mostly run inside of an mcmapply in the run_all_checks_parallel function, which loops over the checks in the rows of metads.

Usage

run_check(
  check,
  fxn_in,
  xls_title,
  pdf_title,
  pdf_subtitle,
  pdf_return,
  verbose
)

Arguments

check

Check name.
fxn_in

Function performing the check.
xls_title

Excel title.
pdf_title

PDF title.
pdf_subtitle

PDF subtitle.
pdf_return

Text to display in PDF if check does not run.
verbose

Whether to display messages while running

Details

to look up documentation for the data checks package, please use command ??sdtmchecks

Value

list with results from the check.
