Outcomes
What happened to patients after their stay: deaths, readmissions and infections picked up in the hospital.
Death rates
The share of patients who died within 30 days of a hospital stay for this condition, adjusted for how sick they were. Lower is better.
About this measure
Patients admitted for treatment sometimes develop serious complications or die. Many of these events can be prevented when hospitals follow best practices. CMS risk-adjusts death rates so hospitals that treat sicker patients are compared fairly.
Unplanned readmissions
The share of patients who came back to a hospital unexpectedly within 30 days of going home. Lower is better.
About this measure
The readmission measures estimate the rate of unplanned readmission to an acute care hospital in the 30 days after discharge. Returning to the hospital disrupts patients’ lives, raises the risk of harmful events like infections, and costs more. Hospitals that give high quality care can keep patients from returning.
Infections caught in the hospital
Infections compared with the number expected for a hospital like this one. 1.0 is as expected; below 1.0 is better.
About this measure
Infections are reported using a standardized infection ratio. The SIR compares the actual number of infections at a hospital to a national benchmark based on data reported to the CDC’s National Healthcare Safety Network (NHSN).
Timely care and patient experience
Emergency department waits, whether recommended treatments were given, and how patients rated their stay.
Time spent in the emergency department
How long patients typically spent in the emergency department before leaving. Shorter is better.
About this measure
Timely emergency care is essential for good outcomes. Delays can reduce the quality of care and increase risk and discomfort for patients with serious illnesses or injuries. Waiting times vary with the number of patients seen, staffing, efficiency, admitting procedures and the availability of inpatient beds.
Recommended care
How often the hospital gave care that research shows gets the best results. Higher is better.
About this measure
Sepsis is a complication that occurs when the body has an extreme response to an infection. It damages organs and can be life-threatening. Sepsis can turn into septic shock, which has a higher risk of death. Identifying sepsis early and starting appropriate care quickly increases the chance of survival.
The septic shock measures focus on adults with severe sepsis or septic shock and check whether medically required interventions were given within three hours (first steps) and six hours (remaining steps).
Patient experience
How recently discharged patients rated their stay on the national HCAHPS survey, as a 0–100 score. Higher is better.
About this measure
Patients review their care using the HCAHPS survey, which covers overall rating, willingness to recommend, cleanliness, quietness, nurse and doctor communication, communication about medicines and more. CMS converts each set of responses to a number between 0 and 100 and averages them into a linear mean score that captures the full distribution of answers.
Costs and value
What care costs Medicare and patients, how it relates to outcomes, and the hospital’s own costs and staffing.
Payments for an episode of care
Average total paid, by Medicare and the patient, for care from admission through the following 30 days (90 for hip/knee replacement).
About this measure
The payment measures add up all payments for care starting the day the patient enters the hospital: payments to the hospital, doctor's office, skilled nursing facility and hospice, plus patient copayments. Risk adjustment accounts for patient age, medical history and other conditions, and removes differences unrelated to care such as geographic pricing.
Value of care
Death rate and payment for the same condition, side by side. Hospitals toward the lower left have both lower death rates and lower payments.
About this measure
Looking at payment together with quality-of-care measures such as death rates lets you compare the value of care between hospitals. Lower and to the left (low death rate, low payment) is the best combination.
Costs versus charges
How a hospital’s actual costs compare with what it lists as charges. Closer to 1 means list prices are closer to costs.
About this measure
Hospitals list charges that are usually much higher than what care costs them. The cost-to-charge ratio shows how far apart the two are. Values are calculated from the hospital’s annual Medicare cost report.
Employees on payroll
Estimated full-time-equivalent staff, from the hospital’s Medicare cost report.
Doctors and specialties
Which kinds of doctors are affiliated with the hospital, and which specialties are unusually common there.
Doctors by specialty
Doctors affiliated with this hospital, grouped by primary specialty.
About this measure
The RCA calculation compares a specialty’s share of all doctors at a given hospital with that specialty’s share across all hospitals.
