Quality Report

ASC Quality Collaboration Quality Report

First Quarter 2023

During 2020, the ASC Quality Collaboration developed a new data platform for the collection and reporting of ambulatory surgical center (ASC) quality data. That new platform was used throughout 2021 to compile benchmarking data. Starting with First Quarter 2022, the most recent four quarters of data are included in this report, along with the 2022 annual (Q1 through Q4 2022) rate for each measure.

It should be noted that two measures were retired from this report in 2020. These two measures are Prophylactic IV Antibiotic Timing and Appropriate Surgical Site Hair Removal. As a result, data for these two measures is no longer included in the quality 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 First Quarter 2023 data was collected from 2,050 ASCs. The following organizations agreed to collect and submit clinical quality data reflecting patient admissions* from January 01 through March 31:

  • Ambulatory Surgery Center Association
  • AMSURG
  • California Ambulatory Surgery Association
  • Covenant Physician Partners
  • HCA Ambulatory Surgery Division
  • Proliance Surgeons
  • Regent Surgical Health
  • SCA Health
  • Surgery Partners
  • United Surgical Partners International (USPI)
  • ValueHealth
  • Visionary Enterprises, Inc.

This report presents aggregated performance data for ASC facility-level quality measures developed by the ASC Quality Collaboration:

      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 Kathy Wilson, Executive Director, ASC Quality Collaboration at kathy.wilson@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.

      2023Q1 Rate of Patient Falls

      0.157 per 1000 admissions

      Represents 2,499,040 ASC admissions seen at 2,049 ASCs between 2023-01-01 and 2023-03-31

      The data trends for this measure over the last four quarters as well as an annual rate for 2022 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.

      2023Q1 Rate of Patient Burns

      0.017 per 1000 admissions

      Represents 2,495,914 patient admissions seen at 2,045 ASCs between 2023-01-01 and 2023-03-31

      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.

      2023Q1 Rate of Hospital Transfers/Admissions

      0.812 per 1000 admissions

      Represents 2,495,510 patient admissions seen at 2,050 ASCs between 2023-01-01 and 2023-03-31

      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.

      2023Q1 Rate of Wrong Site, Side, Patient, Procedure, Implant Events

      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 at the time of surgery. Normothermia helps reduce the risk of surgical complications, including the risk of developing an infection at the surgical site.

      The percentage 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.

      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.
