If your team is responsible for STS registry abstraction, the current state of the healthcare industry has not made the job easier. Staffing shortages, tighter submission windows, and periodic updates to the STS Data Collection Forms have combined to put real pressure on cardiac surgery programs that once managed abstraction comfortably in-house.
This article looks at what is actually changing STS registry abstraction this year, and how Clinical Registry Solutions (CRS) helps hospitals keep their Adult Cardiac Surgery Database, General Thoracic, Congenital Heart Surgery, and Intermacs/Pedimacs submissions accurate and on schedule.
Why is STS Registry Abstraction Getting Harder for Hospitals?
The Society of Thoracic Surgeons National Database is one of the most detailed clinical outcomes registries in the country, and that level of detail is exactly what makes STS registry abstraction so demanding. A single cardiac surgery chart can take an experienced abstractor well over half an hour to complete correctly, depending on the case complexity and how many procedures and complications need to be captured.
That workload has become harder to staff. Abstractors who are qualified to work in the STS Adult Cardiac Surgery Database need clinical training, familiarity with cardiac surgical documentation, and enough registry experience to apply STS-specific definitions consistently. That is not a role most hospitals can fill quickly when someone leaves, and it is not a role that tolerates a long learning curve while patients keep coming through the operating room.
At the same time, many programs are not managing a single database. Hospitals participating in the STS National Database often support the Adult Cardiac Surgery Database alongside the General Thoracic Surgery Database, the Congenital Heart Surgery Database, or the Intermacs/Pedimacs registry, and each one carries its own definitions, submission cycles, and update schedule. When the STS periodically revises its Data Collection Forms, every abstractor working in that database needs updated training before the next data harvest, or accuracy starts to slip.
Add in routine turnover, PTO, and the reality that STS abstraction competes for the same time as chart review, audit prep, and other quality reporting duties, and it becomes clear why so many quality directors and registry managers are actively looking for outside support rather than trying to absorb the gap internally.
There is also a scale factor that is easy to underestimate. The STS National Database now captures data on the large majority of adult cardiac surgery performed across the country, from more than a thousand participating institutions. That national scope means the definitions, risk models, and reporting expectations tied to STS registry abstraction are held to a high standard, and hospitals are effectively being compared against a very large and detailed national benchmark.
A program that falls behind on abstraction volume or lets accuracy slip is not just missing an internal deadline, it is showing up incomplete or inconsistent against a dataset that surgeons, quality leaders, and accrediting bodies all rely on.
For health systems running more than one hospital, the complexity compounds further. A multi-facility system may have several sites participating in the Adult Cardiac Surgery Database at different volumes, with different internal staffing levels and different documentation habits from one EMR build to the next.
Keeping abstraction consistent across those sites, so that a case at one hospital is coded the same way as a similar case at another, takes coordination that a single internal abstractor per site usually cannot provide on their own.
→ Is your STS registry abstraction team stretched across too many databases, sites, or too little coverage? CRS provides clinician-trained abstraction support built specifically for the demands of the STS National Database.
How Does Clinical Registry Solutions Approach STS Registry Abstraction Differently?
Clinical Registry Solutions was built around a simple idea: registry abstraction is clinical work, and it should be done by people with clinical backgrounds. Every CRS abstractor working in STS registry abstraction is U.S.-based and clinician-trained, not an offshore data entry team working from a script.
That distinction matters more in STS abstraction than almost anywhere else in registry work. Correctly capturing operative details, complications, and risk factors in the Adult Cardiac Surgery Database requires someone who can actually interpret an operative note or a progress note the way a clinician would, not just search for keywords.
CRS abstractors, many of whom are registered nurses or have direct cardiovascular or surgical documentation experience, are trained specifically against STS definitions before they touch a live account.
CRS also builds version management into the process rather than treating it as an afterthought. When the Society of Thoracic Surgeons updates its Data Collection Forms, CRS retrains its abstractors and validates against test cases before the change affects live submissions, so hospitals are not left reconciling data collected under two different standards.
This is one of the areas hospitals evaluating a registry data abstraction partner should ask about directly, since a program that falls behind on version updates can end up with inconsistent data across a submission cycle.
That same clinical grounding shows up in how CRS handles the parts of STS registry abstraction that are hardest to automate or hand off to a general coder. Capturing operative approach, valve and graft details, complication timing, and risk factor documentation accurately requires reading a note the way a surgeon or a cardiovascular nurse would read it, not just scanning for a keyword.
CRS abstractors are trained to recognize when documentation is ambiguous or incomplete and to know when a question needs to go back to the clinical team rather than being guessed at, which is exactly the kind of judgment call that keeps a hospital’s risk-adjusted outcomes data trustworthy.
Perhaps most importantly, CRS works entirely inside the hospital’s existing systems. Whether a program runs on Epic, Cerner, Meditech, or another EMR, CRS abstractors work directly within that environment and the STS software the hospital already uses. There is no new platform to license, no software migration project, and no disruption to how surgeons, coordinators, and quality staff already work.
That platform-agnostic approach is part of why CRS is able to support health systems managing STS abstraction alongside other cardiovascular quality programs, including the value CRS helps hospitals capture from registry data once submissions are accurate and complete.
→ Do you need STS registry abstraction support that works inside your current EMR without a new software rollout? CRS integrates directly into your existing systems so your team’s workflow does not change.
What Does Clinical Registry Solutions Do When a Hospital Is Behind on STS Submissions?
A backlog in STS registry abstraction rarely announces itself gradually. It usually shows up all at once, after a resignation, an extended leave, or a stretch of unusually high case volume, and by the time it is visible to leadership, a submission deadline is already close.
CRS’s backlog clearance model is built for exactly that scenario. Because CRS maintains a bench of abstractors already trained across the STS Adult Cardiac Surgery Database, General Thoracic Surgery Database, Congenital Heart Surgery Database, and Intermacs/Pedimacs registry, hospitals do not need to wait through a lengthy hiring and onboarding cycle to get help. CRS can typically begin working a backlog within days of a signed agreement, not months.
The approach is also designed to be temporary when that is all a hospital needs. Some programs bring CRS in for a defined backlog clearance project and return to a fully internal model once caught up. Others find that supplemental support becomes a permanent part of how they manage STS abstraction, especially in cardiac surgery programs where case volume has grown faster than internal staffing.
Either way, CRS scopes the engagement around what the hospital actually needs rather than pushing a one-size-fits-all contract, which ties back to how CRS helps hospitals build audit-ready clinical registry programs that hold up under pressure even when internal capacity is limited.
Backlog work also carries a real risk that is easy to overlook until it happens: rushing charts to catch up on a deadline. A hospital under pressure to submit on time can end up trading speed for accuracy, which trades one problem for another. CRS’s backlog process is built to avoid that tradeoff by pulling in additional trained abstractors rather than pushing existing staff to work faster, so the pace of catching up does not come at the cost of the accuracy the submission depends on.
Every chart abstracted during a backlog project goes through the same IRR validation as routine, day-to-day abstraction, which means a hospital coming out of a backlog clearance engagement is not left with a stretch of lower-confidence data sitting inside an otherwise accurate submission history.
→ Is your STS submission deadline approaching faster than your team can catch up? CRS can begin clearing a backlog within days using abstractors already trained in STS-specific definitions.
How Does Clinical Registry Solutions Support STS Accuracy and Audit Readiness?
Accuracy is the entire point of STS registry abstraction. Data that is incomplete or inconsistently coded does not just create audit risk, it also undermines the benchmarking and quality improvement value that hospitals participate in the STS National Database to get in the first place.
CRS maintains a validated Inter-Rater Reliability rate of 98.3% or higher across the more than 25 registries it supports, including the STS databases. That figure is not a one-time test score. CRS runs continuous IRR monitoring, which means abstractor accuracy is checked on an ongoing basis rather than verified once during onboarding and never revisited.
When discrepancies do turn up, CRS treats them as a feedback opportunity rather than simply a correction. Abstractors receive direct feedback on missed or inconsistent data points, and CRS works with hospital teams to identify documentation gaps at the source, whether that means a note that consistently lacks a required data element or a workflow issue that is making certain fields hard to capture.
That kind of feedback loop connects directly to the work CRS does around data integrity in clinical registries more broadly, since STS accuracy depends as much on documentation quality as it does on the abstractor interpreting it.
CRS also supports the practical side of audit preparation, including discrepancy resolution and coordination directly with STS on data questions when needed. For hospitals preparing for a site visit or an internal quality review, that means the abstraction team is not a black box between a chart and a submission, but a resource the hospital can actually rely on when questions come up.

Full-Service vs. Supplemental STS Support from Clinical Registry Solutions
Not every hospital needs the same amount of help, and CRS structures its STS registry abstraction support around two general models rather than forcing every account into the same shape.
Full-service abstraction means CRS manages the entire STS abstraction workflow for a database, from chart pull through submission-ready data. This model tends to fit hospitals that do not have the internal staffing to support a dedicated STS abstractor at all, smaller and mid-sized programs where hiring a specialist for a single registry is not practical, or health systems consolidating STS abstraction across multiple facilities under one consistent process.
Supplemental support is built for hospitals that already have an internal abstractor or a small internal team but need additional capacity during specific periods, such as a case volume spike, an extended leave, or the run-up to a submission deadline.
In this model, CRS abstractors work alongside the hospital’s existing staff rather than replacing them, following the same definitions and documentation conventions so the data stays consistent regardless of who abstracted a given chart.
Both models run on the same one-year, cancellable contract structure with 30 to 60 days’ notice, and both are billed transparently with no platform or licensing fees layered on top. That flexibility matters in STS abstraction specifically, because case volume and staffing needs in cardiac surgery programs can shift from one quarter to the next in a way that a rigid, long-term vendor contract does not accommodate well.
→ Would supplemental STS registry abstraction support relieve pressure on your internal team without a long-term commitment? CRS scales up or down based on what your program actually needs.
What Should Hospitals Look for in an STS Registry Abstraction Partner?
Hospitals evaluating outside help for STS registry abstraction are usually comparing a mix of registry-focused vendors, larger enterprise data abstraction companies, and software platforms that promise automated abstraction. Each has tradeoffs worth understanding before signing a contract.
Clinical background matters more in STS abstraction than in many other registries, given the volume of operative and procedural detail involved. A vendor that primarily hires general medical coders rather than clinically trained abstractors may move faster on price but can struggle with the more nuanced clinical judgment calls the Adult Cardiac Surgery Database requires.
It is worth asking directly whether abstractors are onshore or offshore, and whether they have specific experience in the STS databases your program participates in, not just general registry experience.
Onboarding speed and contract flexibility are also worth comparing closely. Larger, enterprise-oriented vendors can offer strong infrastructure but sometimes come with longer onboarding timelines and less flexibility for mid-sized hospitals that do not need an enterprise-scale engagement.
On the other end, software-only platforms promising fully automated abstraction can reduce some manual effort but generally still require clinical oversight for the kind of complex chart review STS registries demand, since automated tools can miss context that a trained abstractor would catch.
CRS positions itself specifically for hospitals that want registry-specific expertise without enterprise-level rigidity: onshore clinician-trained abstractors, flexible full-service or supplemental engagement, and a model built to fit hospitals of all sizes rather than requiring a large-scale system rollout.
That is a meaningful part of the broader conversation happening across the industry right now about registry management software versus human abstraction, particularly for a registry as clinically detailed as STS.
It is also worth thinking beyond STS in isolation when choosing a partner. Most cardiac surgery programs are not managing STS abstraction as their only registry commitment. A program may also be supporting NCDR cardiac catheterization data, Get With The Guidelines initiatives, or Core Measures reporting alongside its STS databases, and a vendor that only understands one registry in isolation can end up creating more coordination work rather than less.
CRS’s experience across more than 25 registries means the same account team supporting a hospital’s STS abstraction can often support related cardiovascular quality programs as well, which reduces the number of vendor relationships a quality department has to manage and keeps reporting language consistent across programs.

CRS typically delivers around 30% or more in average cost savings compared to in-house abstraction once salary, benefits, PTO, turnover, and training costs are factored in. Pricing is hourly or case-based with no hidden platform fees, and contracts run on flexible one-year terms cancellable with 30 to 60 days’ notice.
Final Thoughts on STS Registry Abstraction
STS registry abstraction was never simple, and staffing shortages, multi-database complexity, and periodic version updates have made it harder to manage it purely in-house. Hospitals that try to absorb every gap internally often end up trading accuracy or timeliness for staffing convenience, and neither is a tradeoff a cardiac surgery program can really afford.
Clinical Registry Solutions was built to remove that tradeoff. Onshore, clinician-trained abstractors, continuous IRR monitoring above 98.3%, flexible full-service or supplemental engagement, and abstraction that happens entirely inside the systems a hospital already uses. Whether your program needs a backlog cleared, ongoing supplemental coverage, or a full transition of STS abstraction to an outside team, CRS builds the engagement around what your registry program actually needs.
