Timely & Effective Care

Whether hospitals consistently follow evidence-based protocols — measured by process, not by outcome. How quickly, how often, and how completely.

⭐ Feeds Overall Star Rating 📅 Quarterly & annual updates Multiple measure categories

Process measures — what a hospital does, not what happens afterward.

Timely and Effective Care measures track whether hospitals follow established clinical protocols for specific conditions and situations. They measure process — the actions taken during care — rather than outcomes like mortality or readmission. A hospital can do everything right on a process measure and still have a bad outcome; conversely, a good outcome can occasionally happen despite poor process adherence.

The rationale for measuring process is that it is actionable and within a hospital's direct control. A hospital cannot guarantee that a patient won't die — but it can guarantee that a sepsis patient receives antibiotics within three hours. Process measures hold hospitals accountable for the things they can actually control.

These measures cover inpatients and outpatients treated at IPPS and OPPS hospitals, and for some measures, voluntary reporters. Not every measure applies to every hospital.

Star Rating Connection
Timely and Effective Care measures feed Group 5 (Timely & Effective Care) of the Overall Hospital Star Rating — the fifth and final measure group. Not all measures in this program feed the star rating; CMS selects a subset based on reliability and completeness.

Six clinical areas — each with its own measure set and collection cycle.

🦠
Severe Sepsis & Septic Shock
The SEP-1 bundle measures whether hospitals completed all required steps in the first three hours of a severe sepsis or septic shock diagnosis — blood cultures drawn, lactate measured, antibiotics administered, fluids given. One of the most consequential process measures given sepsis mortality rates. Updated quarterly.
SEP-1
🚨
Emergency Department Throughput
How long patients wait in the ED — median time from arrival to departure for admitted patients, time to being seen by a provider, and time to pain medication for fracture patients. ED throughput directly affects patient safety during high-volume periods. Some measures updated quarterly, others annually.
OP-18b OP-18c OP-22 OP-23 ED-2
🧠
Stroke Care
Whether stroke patients received guideline-concordant care — antithrombotic therapy administered by end of hospital day two, anticoagulation therapy for AFib patients, VTE prophylaxis, discharge on statins, and rehabilitation assessment before discharge. Stroke care quality directly affects functional recovery.
STK-02 STK-03 STK-05 STK-06
🩸
Venous Thromboembolism Prevention
Whether patients received appropriate blood clot prevention measures — VTE prophylaxis ordered on the day of or the day after admission to ICU, and on the day of or after hospital admission for general medical patients. VTE is a major cause of preventable in-hospital death.
VTE-01 VTE-02
💉
Preventive Care
Immunization rates — specifically influenza vaccination coverage among healthcare personnel. A structural process measure: a hospital that vaccinates its staff reduces infection transmission risk to patients. Updated based on influenza season reporting cycles.
IMM-3
🏥
Safe Use of Opioids & Other Measures
Whether hospitals who prescribed opioids during an inpatient stay also performed a pain assessment using a standardized tool. Additional outpatient measures cover colonoscopy follow-up care, hospital harm events, and cataract surgery outcomes. Refreshed annually.
OP-29 OP-31 OP-40 HH-01 HH-02
Process vs. Outcome: Why the distinction matters for interpretation
A hospital can score 100% on SEP-1 — meaning every sepsis patient received the complete bundle — and still have sepsis patients who die, because sepsis mortality is driven by many factors beyond protocol adherence. Conversely, a hospital with imperfect SEP-1 compliance may have good sepsis outcomes due to other aspects of clinical care. Process measures tell you about consistency and adherence; outcome measures tell you about results. Both are necessary to understand quality — and neither is sufficient alone.

Mixed collection windows — some quarterly, some annual.

Timely and Effective Care is one of the most heterogeneous hospital datasets in terms of update frequency. SEP-1 and the ED throughput measures are refreshed quarterly — making them among the most current data in the CMS system. Most other measures update annually.

Collection periods range from 3 months (the COVID vaccination measure, now discontinued) to 12 months for most measures. Hospitals report some of this data directly through the Hospital Quality Reporting system; other measures are calculated from Medicare claims. The specific data source and submission method varies by measure ID.

All measures are published together in Timely_and_Effective_Care–Hospital.csv on the Provider Data Catalog, with each row representing one hospital's result on one measure for one collection period.
