dc.descriptionThe 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. To read more about the original algorithm, see [Simon et al](https://pubmed.ncbi.nlm.nih.gov/29496546/) (2018). To access the code, select the “View on GitHub” option below.
