This weblog was written in collaboration with David Roberts (Analytics Engineering Supervisor), Kevin P. Buchan Jr (Assistant Vice President, Analytics), and Yubin Park (Chief Knowledge and Analytics Officer) at ApolloMed. Try the answer accelerator to obtain the notebooks illustrating use of the ApolloMed High quality Engine.
At Apollo Medical Holdings (ApolloMed), we allow unbiased doctor teams to supply high-quality affected person care at an reasonably priced price. On the planet of value-based care, “high quality” is usually outlined by standardized measures which quantify efficiency on healthcare processes, outcomes, and affected person satisfaction. A canonical instance is the “Transitions of Care” measure, which tracks the proportion of sufferers discharged from the hospital which obtain essential observe up companies, e.g. their main care supplier is notified, any new drugs are reconciled with their unique routine, and they’re promptly seen by a healthcare supplier. If any of those occasions don’t happen and the affected person meets qualifying standards, there’s a high quality “hole”, i.e. one thing did not occur that ought to have, or vice versa.
Inside value-based contracts, high quality measures are tied to monetary efficiency for payers and supplier teams, creating a fabric incentive to supply and produce proof of top of the range care. The stakes are excessive, each for discharged sufferers who usually are not receiving follow-ups and the projected revenues of supplier teams, well being programs, and payers.
Key Challenges in Managing High quality Hole Closure
Quite a few, non-interoperable sources
A company’s high quality group could monitor and pursue hole closure for 30+ distinct high quality measures, throughout a wide range of contracts. Sometimes, the information required to trace hole closure originates from an analogous variety of Excel spreadsheet studies, all with subtly diversified content material and unstable knowledge definitions. Merging such spreadsheets is a difficult activity for software program builders, to not point out scientific employees. Whereas these studies are essential because the supply of reality for a well being plan’s view of efficiency, ingesting all of them is an inherently unstable, unscalable course of. Whereas all of us hope that latest advances in LLM-based programming could change this equation, in the intervening time, many groups relearn the next on a month-to-month foundation…

Poor Transparency
If the standard group is lucky to have assist wrangling this hydra, they nonetheless could obtain incomplete, non-transparent data. If a care hole is closed (excellent news), the standard group needs to know who’s accountable.
- Which declare was proof of the observe up go to?
- Was the first care supplier concerned, or another person?
If a care hole stays open (dangerous information), the standard group directs their inquiries to as many exterior events (payers, well being plans) as there are studies. Which knowledge sources have been used? Labs? EHR knowledge? Claims solely? What assumptions have been made in processing them?
To reply these questions, many analytics groups try to duplicate the standard measures on their very own datasets. However how are you going to guarantee excessive constancy to NCQA trade commonplace measures?
Knowledge Missingness
Whereas interoperability has improved, it stays largely inconceivable to compile complete, longitudinal medical data in the US. Well being plans measuring high quality accommodate this subject by permitting “supplemental knowledge submissions”, whereby suppliers submit proof of companies, situations, or outcomes which aren’t identified to the well being plan. Therefore, suppliers profit from an inside system monitoring high quality gaps as a test and stability in opposition to well being plan studies. When discrepancies with well being plans studies are recognized, suppliers can submit supplemental knowledge to make sure their high quality scores are correct.
Answer: Operating HEDISⓇ Measures on Databricks
At ApolloMed, we determined to take a primary ideas strategy to measuring high quality. Reasonably than rely solely on studies from exterior events, we applied and acquired NCQA certification on over 20 measures, along with customized measures requested by our high quality group. We then deployed our high quality engine inside our Databricks Delta Lake. All advised, we achieved a 5x runtime financial savings over our earlier strategy. In the intervening time, our HEDISⓇ engine runs over one million members by 20+ measures for 2 measurement years in roughly 2.5 hours!
Frankly, we’re thrilled with the outcome. Databricks enabled us to:
- consolidate a sophisticated course of right into a single software
- cut back runtime
- present enhanced transparency to our stakeholders
- lower your expenses
Scaling is Trivial with Pyspark
In our earlier implementation, an Ubuntu VM extracted HEDISⓇ inputs as JSON paperwork from an on-prem SQL server. The VM was expensive (working 24×7) with 16 CPUs to assist Python pool-based parallelization.
With pyspark, we merely register a Spark Consumer-Outlined Operate (UDF) and depend on the framework to handle parallelization. This not solely yielded vital efficiency advantages, it’s less complicated to learn and talk to teammates. With the flexibility to trivially scale clusters as needed, we’re assured our implementation can assist the wants of a rising enterprise. Furthermore, with Databricks, you pay for what you want. We count on to cut back compute price by a minimum of 1/2 in transitioning to Databricks Jobs clusters.
Parallel Processing Earlier than…
Parallel Processing After…
Traceability Is Enabled by Default
As knowledge practitioners, we’re regularly queried by stakeholders to elucidate surprising modifications. Whereas cumbersome, this activity is essential to retaining the boldness of customers and making certain that they belief the information we offer. If we have carried out our job properly, modifications to measures mirror variance within the underlying knowledge distributions. Different occasions, we make errors. Both means, we’re accountable to help our stakeholders to know the supply of a change.
A screenshotted measure. “Why did this variation?! It was 52% final Thursday”
Within the Databricks Delta Lake, the capability to revert datasets is a default. With a Delta Desk, we will simply examine a earlier model of a member’s file to debug a difficulty.
We have now additionally enabled change knowledge seize on smaller mixture tables which tracks element stage modifications. This functionality permits us to simply reproduce and visualize how a price is altering over time.
Dependable Pipelines with Standardized Codecs
Our high quality efficiency estimates are a key driver pushing us to develop a complete affected person knowledge repository. Reasonably than studying of poorly managed diabetes as soon as a month by way of well being plan studies, we favor to ingest HL7 lab feeds day by day. In the long run, organising dependable knowledge pipelines utilizing uncooked, standardized knowledge sources will facilitate broader use instances, e.g. customized high quality measures and machine studying fashions skilled on complete affected person data. As Micky Tripathi marches on and U.S. interoperability improves, we’re cultivating the interior capability to ingest uncooked knowledge sources as they develop into obtainable.
Enhanced Transparency
We coded the ApolloMed high quality engine out to supply the actionable particulars we have at all times wished as customers of high quality studies. Which lab met the numerator for this measure? Why was this member excluded from a denominator? This transparency helps report customers perceive the measures they’re accountable to and facilitates hole closures.
