| GENERAL DESCRIPTION |
Visit Tracking is a utility that can be used by a variety of VISTA modules
(usually via PCE), with potential benefits for clinical, administrative,
and fiscal applications. Visit Tracking will allow VISTA packages to link
an event to a patient visit entry, thereby linking that event to any
number of events occurring throughout the hospital during the patient's
outpatient and/or inpatient episode.
Visit Tracking is not a stand-alone application. Other packages will
normally call PCE, which will handle the calls to Visit Tracking.
The key to the creation of visits will be to ensure the clinical
meaningfulness of visits. The creation of visits is facilitated by the
Visit Tracking module. In order to ensure a consistent implementation of
visit creation across packages, each package needs to have an agreement
with the Visit Administrator to create visits.
This section describes the guidelines which should be used for VA
developers populating visits in the Visit file. These guidelines are based
on a combination of the experience of Albuquerque's joint venture sharing,
IHS' PCC pilot test at Tucson VAMC, MCCR data capture pilots, HSR&D
workload reporting studies at Hines VAMC, and DMMS/DSS event data capture.
The purpose of the VISIT file in the VA:
The VISIT file has multiple purposes. The primary role is to record when
and where clinical encounters related to a patient have occurred. Visits
will be recorded for both Outpatient and Inpatient encounters.
Outpatient encounters include scheduled appointments and walk-in
unscheduled visits.
Inpatient encounters include the admission of a patient to a VAMC and
any clinically significant change related to treatment of that
patient. For example, a treating specialty change is clinically
significant, whereas a bed switch is not. The clinically significant
visits created throughout the inpatient stay are related to the
inpatient admission visit.
If the patient is seen in a clinic while an Inpatient, a separate
visit will be created representing the appointment visit?this visit
is related to the Admission visit.
A clinician's telephone communications with a patient may be
represented by a separate visit.
The clinical visits can be viewed from two approaches: 1) a team of
providers can be associated with a primary clinical visit (this is
the traditional view taken by IHS); or 2) a primary clinic visit can
represent the primary provider's care, and a separate visit can be
created to reflect the secondary provider's care.
Additionally, the VISIT file can provide a breakdown of other
ancillary services provided during the clinically significant visit.
Laboratory or Radiology services are other examples of services
provided that could have a separate visit reflecting the service
involvement related to a clinic appointment on the same day.
Create and/or Match Visit Using Input Criteria
^VSIT
INPUT:
VSIT <visit date [and time] in FM format>
VSIT("VDT") may be used instead of VSIT.
(time will default to 12 noon if not
specified)
DFN <patient file pointer>
VSIT("PAT") may be used instead of DFN.
[VSIT(0)] <a string of characters that defines how
the visit processor will function, see
package-wide variables>
[VSIT("<xxx>")] <array with mnemonic subscript>
(used in match logic if VSIT(0)["M")
(for SVC, TYP, INS, CLN, ELG, LOC)
Note: For multiple field values use
[<field value>[^...]]
i.e., VSIT("SVC")="H^D" (will find both)
VSITPKG <package name space>
VSIT("PKG") may be used instead of
VSITPKG.
OUTPUT:
VSIT(<ien>) N^S[^1]
where:
N = <internal entry number of visit>
or -1 if could not get a visit
or -2 if calling package is not
active in Visit Package Parameters
S = <value of .01 field of visit>
1 = <indicates that a new visit was added
VSIT(<xxx>) array passed in with all the entries
defined and the defaulted values added
VSIT(<ien>,<xxx>) returns the data that is stored in the
Visit file in the same format as
VSIT(<xxx>)

I Interactive mode
E Use patient's primary eligibility if not
defined on call with VSIT("ELG").

D Look back "n" number of days for match,
defaults to one (1). D[<number of days>]
i.e., VSIT(0)="D7" e.g., VSIT(0)="D5"
(visit date to visit date - 4) use "D0"
to require exact match on visit date and
time.
M Impose criteria on matching/screening of
visits. Uses the VSIT(<xxx>) array:
Matching elements must equal their

used.
mr VSIT The date (and time) of the visit.
