Patient safety, satisfaction, and high-quality care are key to UC Davis Health's mission as one of California’s top health care providers. That’s why we’re working closely with the Hospital Quality Institute (HQI), the Patient Safety Movement Foundation (PSMF), and the California Hospital Association (CHA) to increase transparency in our patient safety data to help empower you to make the best decisions about your care.

The Quality Transparency Dashboard is designed to provide transparency into how UC Davis Health is performing in comparison to hospitals across California and the entire nation whenever possible. The dashboard shown below displays outcome and program status measures among eight key quality-of-care metrics.

In an effort to share our most recent data with the public, the UC Davis Medical Center performance time period is sometimes more recent than the California and National comparison time periods.


Central Line-Associated Bloodstream Infection (CLABSI)

Reference Measure Period: 10/01/2018 - 09/30/2019

UC Davis Medical Center Measure Period: 07/01/2019 - 06/30/2020

UC Davis Medical Center California Level National Level
0.50 0.71 0.70

Central line-associated blood stream infection (CLABSI): A serious infection that occurs when germs enter the bloodstream through a central line. A central line is a special intravenous catheter (IV) that allows access to a major vein close to the heart and can stay in place for weeks or months. The value shown above is a Standardized Infection Ratio (SIR), which is the ratio of observed-to-expected infections during the measure period. SIRs below 1.00 indicate that the observed number of infections during the measure period was lower than would be expected under normal conditions, whereas values above 1.00 indicate that the observed number of infections was higher than expected. (Lower is better).

Limitations: In the calculation of the Standardized Infection Ratio (SIR), the CDC adjusts for differences between hospitals. However, patient risk factors are not taken into account. These patient-specific variables (e.g., poor skin integrity, immunosuppression) can increase the risk of developing a central line infection. Hence, the SIR for hospitals that care for more medically complex or immunosuppressed patients may not be adequately adjusted to account for those patient-specific risk factors.


Catheter Associated Urinary Tract Infection (CAUTI)

Reference Measure Period: 10/01/2018 - 09/30/2019

UC Davis Medical Center Measure Period: 07/01/2019 - 06/30/2020

UC Davis Medical Center California Level National Level
0.56 N/A .80

Catheter Associated Urinary Tract Infection (CAUTI): A serious infection that occurs when germs enter the bloodstream through a catheter inserted into the bladder (e.g., a Foley catheter). The value shown above is a Standardized Infection Ratio (SIR), which is the ratio of observed-to-expected infections during the measure period. SIRs below 1.00 indicate that the observed number of infections during the measure period was lower than would be expected under normal conditions, whereas values above 1.00 indicate that the observed number of infections was higher than expected. (Lower is better).

Limitations: In the calculation of the Standardized Infection Ratio (SIR), the CDC adjusts for differences between hospitals. However, patient risk factors are not taken into account. These patient-specific variables (e.g., obesity, immunosuppression, diabetes) can increase the risk of developing a catheter associated urinary tract infection. Hence, the SIR for hospitals that care for more medically complex or immunosuppressed patients may not be adequately adjusted to account for those patient-specific risk factors.


Colorectal Surgical-Site Infection (Colon SSI)

Reference Measure Period: 10/01/2018 - 09/30/2019

UC Davis Medical Center Measure Period: 07/01/2019 - 06/30/2020

UC Davis Medical Center California Level National Level
1.69 0.89 0.87

Colorectal surgical-site infection (Colon SSI): An infection (usually bacteria) that occurs after a person has colorectal surgery that occurs at the body site where the surgery took place. While some involve only the skin, others are more serious and can involve tissues under the skin, organs, or implanted material. The value shown above is a Standardized Infection Ratio (SIR), which is the ratio of observed-to-expected infections during the measure period. SIRs below 1.00 indicate that the observed number of infections during the measure period was lower than would be expected under normal conditions, whereas values above 1.00 indicate that the observed number of infections was higher than expected. (Lower is better).

Limitations: Some, but not all patient-specific risk factors are included in the adjustment of the SIR for these types of infections. However, not all relevant risk factors are included (e.g., trauma, emergency procedures). Hence, the SIRs for hospitals performing more complex procedures or with larger volumes of trauma or emergency procedures may not be adequately adjusted to account for those patient-specific risk factors.


Clostridium difficile infection (C. diff)

Reference Measure Period: 10/01/2018 - 09/30/2019

UC Davis Medical Center Measure Period: 07/01/2019 - 06/30/2020

UC Davis Medical Center California Level National Level
0.83 N/A .90

Clostridium difficile infection (C. diff): An infection often presenting with watery diarrhea, abdominal pain and cramping, fever, and other symptoms that can progress to cause severe illness, sepsis, and occasionally death. Overuse of antibiotics, imperfect hand hygiene, and inadequate sterilization techniques can contribute to hospital onset C. diff. The value shown above is a Standardized Infection Ratio (SIR), which is the ratio of observed-to-expected infections during the measure period. SIRs below 1.00 indicate that the observed number of infections during the measure period was lower than would be expected under normal conditions, whereas values above 1.00 indicate that the observed number of infections was higher than expected. (Lower is better)

Limitations: In the calculation of the Standardized Infection Ratio (SIR), the CDC adjusts for differences between hospitals. However, patient risk factors are not taken into account. These patient-specific variables (e.g., age, prior colonization with C. diff.) can increase the risk of developing a C. diff. infection. Hence, the SIR for hospitals that care for more medically complex, older, or immunosuppressed patients may not be adequately adjusted to account for those patient-specific risk factors.


Nulliparous, Term, Singleton, Vertex (NTSV) Cesarean Birth Rate

Reference Measure Period: 01/01/2019 - 12/31/2019

UC Davis Medical Center Measure Period: 01/01/2019 - 12/31/2019

UC Davis Medical Center California Level National Level
25.90 22.90 25.60

Nulliparous, Term, Singleton, Vertex (NTSV) Cesarean birth rate: The percentage of cesarean (surgical) births among first-time mothers who are at least 37 weeks pregnant with one baby in a head down position (not breech or transverse). Lower values indicate that fewer cesareans were performed in the hospital among primarily low risk, first-time mothers.

Limitations: NTSV rates do not take into account certain obstetric conditions, such as placenta previa, that may make Cesarean delivery the safer route for both mother and infant. NTSV rates also do not take into account maternal factors such as obesity, diabetes, or lack of prenatal care that are associated with higher Cesarean section rates.


All Cause Inpatient Mortality Index

Measure and Reference Period: 07/01/2019 - 06/30/2020

UC Davis Medical Center California Level National Level
0.80 0.90 0.92

All Cause Inpatient Mortality Index: The mortality index is the ratio of observed to expected inpatient mortality, also referred to as the O/E Ratio. An O/E ratio above 1.0 indicates an observed mortality higher than the Vizient Expected Value. The expected mortality for a population is predicted by the 2019 Vizient MS-DRG based mortality risk model, in this case specifically reflecting Academic Medical Centers. 

Data from The Vizient Clinical Data Base/Resource Manager™ is used by permission of VIZIENT, all rights reserved. This tool is an analytic platform for performance improvement populated by hundreds of health systems and community hospitals nationwide, including nearly all academic medical centers. It includes comparative benchmarks such as demographic, mortality, length of stay, complication rates, readmission rates, diagnosis, procedure, resource utilization and other information.

Limitations: Risk adjustment models use administrative coding data, which may not reflect all mortality risk factors.


Sepsis Mortality

Measure Period: 01/01/2018 - 12/31/2018

UC Davis Medical Center California Level National Level
14.12 14.30 25.00

Sepsis mortality: Percent of patients, with a severe infection, who die in the hospital. Most sepsis cases (over 90%) start outside the hospital. Lower percentage of death indicates better survival.

Limitations: Use of discharge/administrative data is limiting since such data has lower specificity for diagnoses than clinical data. In addition, without risk adjustment for differences in patient-specific factors, comparing rates among hospitals is difficult.


Surgical Clipping of Intracranial Aneurysms

Reference Measure Period: 10/01/2018 - 09/30/2019

UC Davis Medical Center Measure Period: 07/01/2019 - 06/30/2020

UC Davis Medical Center California Level National Level
Clipping Mortality Index 0 0.88 0.92
Clipping CMI 7.2723 7.9794 6.6189

Surgical Clipping of Intracranial Aneurysms: Surgical clipping is a procedure used to treat unruptured and ruptured brain aneurysms.The mortality index is the ratio of observed to expected mortality, also referred to as the O/E Ratio. An O/E ratio above 1.0 indicates an observed mortality higher than the Vizient Expected Value. Case Mix Index (CMI) is the average relative DRG weight of a hospital’s inpatient discharges, calculated by summing the MS-DRG weight for each discharge and dividing the total by the number of discharges. The CMI reflects the diversity, clinical complexity, and resource needs of all the patients in the hospital. A higher CMI indicates a more complex and resource-intensive case load.
