How to capture the patient journey?
Vision and mission of a healthcare organization
▪ Vision
▪ Working together to create the best health systems in the world.
▪ Mission Statement
▪ Together, we will improve the performance of our health systems by driving quality, accountability, innovation and value.
What does the patient journey look like?

What really does the patient journey look like?
https://www.cancercare.on.ca/ocs/qpi/dispathmgmt/pathways/colopath/
“Pathways are flowcharts that show a high-level overview of the care a cancer patient in Ontario should receive. Pathways focus on one type of cancer, during a specific phase of the cancer journey, with the understanding that the patient journey differs from one cancer to another.”
How do we capture this in the available datasets?
Health Analysts’ Toolkit, Health Analytics Branch, Winter 2012
Two possible sources
for surgery data
What information are captured in the datasets?
▪ Discharge Abstract Database (DAD):
▪ “patient-level data are collected at the time of service in participating institutions. After the discharge, a medical records coder at the hospital completes an abstract according to instructions in the CIHI abstracting manual.” (pg. 7)
▪ OHIP Claim’s history database:
▪ “provider billings through the Ontario Health Insurance Plan (OHIP)” (pg. 7)
▪ “CHDB is designed for the assessment and processing of claims, its use for other purposes—such as measuring utilization of services or estimating conditions based on diagnoses—is secondary. Care must be taken with interpretation and analysis.” (pg. 7)

What is the relationship between the two databases?
Comparison of the two databases: unit of analysis
DAD
▪ Each observation represents a discharge
▪ Patients transferred to another facility (after discharge) possibly for the same condition are in multiple observations
CHDB
▪ Each observation represents one claim (NOT visit or activity)
▪ e.g. A visit to the doctor’s office can be captured by multiple observations depending on what procedures were performed
Not absolutely comparable
Comparison of the two databases: how information is captured
DAD
▪ Surgery information is captured by CCI codes
▪ “CCI specifies more precisely than ever before what interventions and services health professionals provide. ”
▪ Multiple fields to capture interventions
CHDB
▪ Surgery information is captured by OHIP fee codes
▪ Schedule benefit: http://www.health.gov.on.ca/english/providers/program/ohip/sob/physserv/sob_master20160406.pdf
▪ Modifier fee codes for additional payment (e.g. laproscopic surgery E747)

Comparison of the two databases: activity dates
DAD
▪ Admission date
▪ Discharge date
▪ Intervention date
CHDB
▪ Service date
▪ Admission date
Not absolutely comparable
▪ Not 100% match
▪ Dates can be different (actual mismatch vs. coding variability)
▪ Type of surgery can be different (actual mismatch vs. coding variability)
▪ Institution which the surgery occurred can be different (actual mismatch vs. coding variability)
Comparison of the two databases: summary
Might requires both sources to fully capture surgical resection information.
Reconciliation of mismatches is very time consuming!
…”its use for other purposes—such as measuring utilization of services or estimating conditions based on
diagnoses—is secondary”
Summary
▪ Prior to thinking about advanced analytics, make sure you know what data sources you need and what information you need▪ Sometimes multiple sources are needed (Warning! Matching can be
challenging)
▪ Understand how the data is captured prior to you extract data▪ Understand what is and is not captured in data sources
▪ Be aware of dates, unit of analysis, diagnosis codes (ICD-9, ICD10, ICD-O-3, OHIP diagnosis codes), etc.
▪ Read database documentation and ask colleagues around you
End result: Save time!
