Details
In PPMI 1.0, the VISSTAT table had no directly corresponding CRF, though many of the variables in the VISSTAT table had similarities to those captured in the SIG table (which did have an associated CRF). In PPMI 2.0, VISSTAT has a CRF associated with it, and the SIG table has been removed entirely from the schema.
The VISSTAT CRF directly captures the following: VISTYPE, VISOUC, VISOUCRSN, VISWW, VISOOWRSN, and VISOOWCM
EDC Metadata
The other variables that exist in the VISSTAT table (EVENT_START, EVENT_END, VISMSRSN, VISMSCM) are all collected through the metadata of the EDC system.
Out of Clinic Visits
VISOUC was added partway through the study on 2020/11/11. The “Out of Clinic” (5) option was removed from VISTYPE. To resolve difference between version of this form:
Previous “Out of Clinic” responses to
VISTYPEare turned into “Yes” responses toVISOUCin processing prior to transfer to LONI.Codes for
VISTYPEare remapped to remove option 5 (out of clinic). Values of 5 are removed as described in the above point and values of 6 are changed to 5.
Overlap with SIG in 1.0
In 1.0,
VISMSRSNandVISMSCMwere collected through the SIG CRF (these variables also existed in 1.0’s VISSTAT table, though there was no associated VISSTAT CRF). These variables capture the reason a visit was missed, and any associated comments. These variables are also captured in 2.0, though they are captured through the EDC metadata (as stated above).In 1.0,
VISSTATandVISSTCMwere collected through the SIG CRF.VISSTATcollects information about when a visit was completed (e.g. out of window, unscheduled, etc.) and who completed it.VISSTCMcollects any additional comments. In 2.0, the type of visit is largely captured throughVISTYPE, and information on a visit’s out of window status is captured throughVISOUCRSN.The possible values in
VISMSRSNhave been harmonized to account for versions of the question that existed both in SIG in the original phase of PPMI and in VISSTAT in the extended phase. “Other” in the extended version has been recoded from 11 to 20 and a new code 11 was added to account for a possible value in the original version.
Other Removed Columns
Many additional variables that existed in PPMI 1.0 were removed from the VISSTAT table in PPMI 2.0. In many cases, this was done because the information captured by these variables was either redundant, or was removed to help simplify the table.
