The Differences Between The 5 Major Stroke Measure Sets

This post is a guide to understanding the differences between the five major stroke measure sets. It’s a nightmare trying to keep straight this wide range of acronym-filled information. So, I’ve attempted to structure it in a way that will be a reference for you.

Here’s how this post is organized.

Part 1: A review of the different stroke measure sets

This section includes the measure type (inpatient vs outpatient), the number of measures in the set, which certification the measure set is a part of, a list of the measures in the set and the associated algorithm.

Part 2: A review of the different stroke certifications

This section reviews The Joint Commission certifications and clarifies the CMS accreditation requirement. I also included the complete list of measures required for each certification.

Part 3: How to report stroke information

In the final section, I review the way this information is submitted to The Joint Commission and CMS.

Oh, also, I included a ton of resources and links throughout this article and a specific list of resources at the end.

Part 1: A review of the different stroke measure sets

There are five major stroke measure sets. You’ll see them abbreviated like this:

  1. CSTK
  2. STK
  3. ASR IP/OP
  4. STK OP
  5. OP STK

Measure Set #1
CSTK: Comprehensive Stroke or C-Stroke

Measure Type: Inpatient
Number of Measures Included: 10
Certification Requirement: The Joint Commission’s Comprehensive Stroke Certification

*Note: There are additional measures needed to fulfill this certification. Program details are found in Part 2. 

Measures:

Links to measure specifications

Set Measure ID Measure Short Name 
CSTK-01 National Institutes of Health Stroke Scale (NIHSS Score Performed for Ischemic Stroke Patients)
CSTK-03

Severity Measurement Performed for SAH and ICH Patients (Overall Rate)

CSTK-04 Procoagulant Reversal Agent Initiation for Intracerebral Hemorrhage (ICH )
CSTK-05 Hemorrhagic Transformation (Overall Rate)
CSTK-06 Nimodipine Treatment Administered
CSTK-08 Thrombolysis in Cerebral Infarction (TICI Post-Treatment Reperfusion Grade)
CSTK-09 Arrival Time to Skin Puncture
CSTK-10 Modified Rankin Score (mRS at 90 Days: Favorable Outcome)
CSTK-11 Rate of Rapid Effective Reperfusion From Hospital Arrival
CSTK-12

Rate of Rapid Effective Reperfusion From Skin Puncture


Algorithm:

CSTK: Comprehensive Stroke or C-Stroke Algorithm Part 1

Once a patient is qualified, he/she moves to the second part of the algorithm which tells you which sub-population he/she falls into.

  • Ischemic Stroke
  • Ischemic Stroke with Procedure (Thrombolytic Therapy or Mechanical endovascular therapy)
  • Hemorrhagic Stroke

CSTK: Comprehensive Stroke or C-Stroke Algorithm Part 2

Measure Set #2
STK: Stroke

Measure Type: Inpatient
Number of Measures Included: 8
Certification Requirement: The Joint Commission’s Primary Stroke Certification

Measures:

Set Measure ID  Measure Short Name 
STK-1

Venous Thromboembolism (VTE Prophylaxis)

STK-2

Discharged on Antithrombotic Therapy

STK-3

Anticoagulation Therapy for Atrial Fibrillation/Flutter

STK-4 Thrombolytic Therapy
STK-5

Antithrombotic Therapy By End of Hospital Day Two

STK-6 Discharged on Statin Medication
STK-8

Stroke Education

STK-10 Assessed for Rehabilitation

 

Algorithm:

STK: Stroke Algorithm

Much like we saw how cases fall into their respective sub-populations with CSTK, cases for STK use the same criteria when determining which sub-population a case will qualify for. If the Principal Diagnosis code falls on Table 8.1 it will be placed in the Ischemic Stroke, or sub-pop 1 and if it has a Principal Diagnosis code that falls on Table 8.2, then it will be placed in the Hemorrhagic Stroke or sub-pop-2.

The next measure set we review is abbreviated ASR-IP/OP. Here I have broken it into the inpatient measure set and the outpatient measure set.

Measure Set #3-1
ASR-IP: Acute Stroke Ready – Inpatient

Measure Type: Inpatient
Number of Measures Included: 3 process measures
Certification Requirement: The Joint Commission’s Disease-Specific Care Certification

Measures:

Set Measure ID Measure Short Name 
ASR-IP-1 Thrombolytic Therapy: Inpatient Admission
ASR-IP-2 Antithrombotic Therapy By End of Hospital Day 2
ASR-IP-3

Discharged on Antithrombotic Therapy

 

Algorithm:

ASR-IP: Acute Stroke Ready – Inpatient Algorithm

Measure Set #3-2
ASR-OP: Acute Stroke Ready – Outpatient 

Measure Type: Outpatient
Number of Measures Included: 2 process measures
Certification Requirement: The Joint Commission’s Disease-Specific Care Certification

Measures:

Set Measure ID  Measure Short Name 
ASR-OP-1 Thrombolytic Therapy: Drip and Ship
ASR-OP-2

Door to Transfer to Another Hospital
**RETIRED Effective July 1, 2021**

 

Algorithm:

ASR-OP: Acute Stroke Ready – Outpatient Algorithm

Note: All Joint Commission certified acute stroke ready hospitals, as well as those seeking initial certification, will be required to collect the STK-OP-1 Door to Transfer to Another Hospital measure for discharges on and after July 1, 2021. Data collection for STK-OP-1 will replace ASR-OP-2. The change in the performance measure requirements for Acute Stroke Ready Hospitals, (i.e., STK-OP-1 replacing ASR-OP-2 effective with discharges on and after July 1, 2021) can be found in several places. The primary source is the Disease-Specific Care Certification Manual, ASRH addendum. In the specifications manual, Version 2021B, it is in Section 7: Joint Commission National Quality Measures Data Processing, Joint Commission Stroke Measures table: https://manual.jointcommission.org/releases/TJC2021B/TransmissionChapterTJC.html 

Measure Set #4
STK-OP: Stroke Outpatient

*Note: Significant changes to this measure set begin July 1, 2021.

Measure Type: Outpatient
Number of Measures Included: There are five process measures (you’ll see one additional measure listed below that is not reported and one additional measure that is retired starting with July 1, 2021 discharges). TJC is adding three additional measures beginning with July 1, 2021 discharges.
Certification Requirement: The Joint Commission’s Primary Stroke Certification

Measures:

Set Measure ID Measure Short Name 
STK-OP-1 Door to Transfer to Another Hospital

Honestly though – Stroke Outpatient versus Outpatient Stroke. What is wrong with these people making it so complicated for us?

Here’s a good reference document in case you get confused. You can download it or email it to yourself to help you remember.

Part 2: A review of the different certifications

To begin, I will clarify the two Measure Stewards we are reviewing today (there are many other Measure Stewards out there). The Measure Steward refers to the organization that is responsible for providing the required measure information for the measure maintenance process that occurs approximately every three years. They are responsible for making the necessary updates to the measure and for informing NQF (National Quality Forum) about any changes that are made to the measure on an annual basis.

In this post we are either referencing CMS or The Joint Commission as the Measure Stewards.

The following links provide you with information available on past, present and future versions of the specification manuals, including release notes, measure information forms, data dictionaries, missing and invalid data, population and sampling, data transmission, tools and resources, and appendices.

In regard to stroke, The Joint Commission has four different types of certification programs that go along with these stroke measure sets. Each certification may require your hospital to submit one or more of the five measure sets we reviewed above. They also could require other measures.

Part 3: How to report stroke information

The two Measure Stewards (CMS and TJC) require hospitals to submit their chart-abstracted data in two different ways. For the purposes of this blog, since we are focusing specifically on stroke measures, there is only one stroke measure that is used for Accreditation purposes by both CMS and TJC: OP-23. Here is a diagram that outlines the submission differences.

CMS and TJC Stroke Measure Submission

The Joint Commission Submission Platforms

At the beginning of 2020, The Joint Commission switched over to the Direct Data Submission Platform (DDSP). Hospitals now have one place to submit both chart-abstracted and eCQM data. The DDS platform is where hospitals submit performance measurement data to The Joint Commissions to meet ORYX ® reporting requirements.

In addition, TJC established the Certification Measure Information Process (CMIP) tool where hospitals must manually enter their certification data for the program certifications we reviewed above (ASR, PSC, TSC and CSC).

Finally, I have listed a few more resources for you. I hope this high-level overview was helpful and can be a reference for you.
