About
R functions including the complex chronic flag, number of body systems, progressive conditions and malignancy, with the most conservative version of the algorithm.
Access Package
Provenance
The algorithm was developed initially by Simon et. al. (Seattle Children's Research Institute) and repurposed as R functions by Hanieh Razzaghi (PEDSnet).

Description
The PMCA algorithm identifies children with complex chronic disease who have accessed tertiary hospital ED, day surgery, or inpatient care sites. These functions were adapted to R to improve use of the algorithm against the PEDSnet database. The PMCA functions include the following processes:
- Produce a PMCA table of observations with a 3-year lookback from the observation_date.
- Compute a table of visit counts for the prior 3 years and flag chronic/complex chronic conditions, malignancy, and progressive conditions for each body system identified for each patient in the cohort.
- Compute the most conservative PMCA algorithm for the complex chronic flag.
- Generate final patient-level flags indicating counts of progressive and malignant conditions, the complex chronic flag, and counts of body systems.
- Generate flags indicating presence of PMCA body systems within the prior 3-year lookback period.
