ASC Quality Collaboration Quality Report
Fourth Quarter 2025
This report includes the most recent four quarters of data, along with the past annual (Q1 through Q4) rate for each measure.
It should be noted that Prophylactic IV Antibiotic Timing and Appropriate Surgical Site Hair Removal are previous measures that have been retired and are not included in this report. However, the specifications for those two measures are still included in the Implementation Guide.
This public report has been made possible through the voluntary efforts of participants in the ASC Quality Collaboration. The Fourth Quarter 2025 data was collected from 2,106 ASCs. The following organizations agreed to collect and submit clinical quality data reflecting patient admissions* from 2025-10-01 00:00:00 through December 31:
- Ambulatory Surgery Center Association;
- AMSURG;
- California Ambulatory Surgery Association;
- NueHealth;
- Proliance Surgeons;
- Regent Surgical Health;
- SCA Health;
- Sovereign Healthcare;
- Specialist Management Solutions;
- Surgery Partners;
- Surgery Ventures powered by HCA Healthcare;

- Tenet/United Surgical Partners International (USPI)
This report presents aggregated performance data for the following ASC facility-level quality measures developed by the ASC Quality Collaboration:
- Patient Fall in the ASC
- Patient Burn
- All Cause Hospital Transfer/Admission
- Wrong Site, Side, Patient, Procedure, Implant
- Normothermia

Specifications for these measures can be found on the ASC Quality Collaboration website and are included in the Implementation Guide. Any comparison to the benchmarks included in this report should only be made if the same specifications are utilized in data collection.
This data and the accompanying information do not present all there is to know about the quality of ASCs. Patients are encouraged to discuss these quality indicators with their local ASC staff and their physician.
The data presented here has been self-reported by participating organizations and has not been independently validated by the ASC Quality Collaboration.
Questions or comments regarding this report may be directed to Nina Goins, Executive Director, ASC Quality Collaboration at nina.goins@ascquality.org.
Patient Fall in the ASC
Falls are an important issue for patients having outpatient procedures or surgery because virtually all patients receive sedatives, anesthetics and/or pain medications as a routine part of their care. The use of these medications increases the likelihood of a fall.
The frequency of ASC admissions experiencing a fall while in the confines of participating ASCs is shown below as a rate per 1000 admissions. Lower rates are better.
2025Q4 Rate of Patient Falls |
0.137 per 1000 admissions |
Represents 2,921,808 ASC admissions seen at 2,104 ASCs between 2025-10-01 and 2025-12-31 00:00:00
The data trends for this measure over the last four quarters as well as an annual rate for 2025 are presented below in both tabular and graphic formats.

Patient Burn
Burns are an important issue for patients having outpatient procedures or surgery because the equipment and supplies routinely used in providing these types of services can increase the risk that a patient will experience an unintended burn.
The frequency of ASC admissions experiencing a burn, regardless of severity, while in the care of participating ASCs is shown below as a rate per 1000 admissions. Lower rates are better.
2025Q4 Rate of Patient Burns |
0.016 per 1000 admissions |

All Cause Hospital Transfer/Admission
ASCs provide surgical services to patients not requiring hospitalization. Therefore, ASCs screen patients referred to their facilities to ensure they can be safely cared for as an outpatient.
The frequency of ASC admissions experiencing a transfer or admission to a hospital upon discharge from participating ASCs is shown below as a rate per 1000 admissions. Not all conditions requiring a hospital transfer or admission result from the care the patient received in the ASC, nor can all medical conditions requiring a hospital transfer or admission be anticipated in advance. Therefore, some level of hospital transfer or admission is expected.
2025Q4 Rate of Hospital Transfers/Admissions |
0.920 per 1000 admissions |
Represents 2,909,488 patient admissions seen at 2,093 ASCs between 2025-10-01 and 2025-12-31 00:00:00

Wrong Site, Side, Patient, Procedure, Implant
Wrong site, wrong side, wrong patient, wrong procedure and wrong implant events are a concern for patients having outpatient procedures or surgery. There are steps that can be taken to help prevent errors such as surgery performed on the wrong part of the body or the wrong side of the body.
The frequency of ASC admissions experiencing a wrong site, wrong side, wrong patient, wrong procedure or wrong implant event while in the care of participating ASCs is shown below as a rate per 1000 admissions. Lower rates are better.
2025Q4 Rate of Wrong Site, Side, Patient, Procedure, Implant Events |
0.024 per 1000 admissions |

Normothermia
Maintaining body temperature within a normal range (normothermia) is important in patients who have general, spinal or epidural anesthesia lasting 60 minutes or more. Normothermia helps reduce the risk of surgical complications, including the risk of developing an infection at the surgical site.
The percent of eligible ASC patients that are normothermic within 15 minutes of arrival into the Post Anesthesia Care Unit (PACU) is displayed below. Higher percentages are better.
2025Q4 Percent of Eligible ASC Patients with Normothermia |

All Cause Emergency Department Visit Within One Day of Discharge
Patients undergoing ambulatory surgery are expected to recover at home following discharge. An emergency department visit within one day of discharge is an unexpected event.
The frequency of ASC admissions experiencing an emergency department visit within one day of discharge is shown below as a rate per 1000 admissions. Not all conditions requiring an emergency department visit result from the care the patient received in the ASC, nor can all medical conditions requiring an emergency department visit following discharge be anticipated in advance. Therefore, some level of emergency department visits following discharge is to be expected.
2025Q4 Rate of All Cause Emergency Department Visits Within One Day of Discharge |
0.601 per 1000 admissions |
Represents 2,867,556 patient admissions seen at 2,071 ASCs between 2025-10-01 and 2025-12-31 00:00:00
