ASC Quality Collaboration Quality Report
3rd Quarter 2019

This public report of ambulatory surgical center (ASC) quality data has been made possible through the voluntary efforts of participants in the ASC Quality Collaboration. The following organizations agreed to collect and submit clinical quality data reflecting patient admissions* from July 1, 2019 through September 30, 2019: Ambulatory Surgery Center Association; AmSurg; California Ambulatory Surgery Association; Covenant Surgical Partners; HCA Ambulatory Surgery Division; Practice Partners in Healthcare, Inc; Regent Surgical Health, Surgical Care Affiliates (SCA); Surgery Partners; United Surgical Partners International (USPI) and Visionary Enterprises, Inc. This quarter's data has been collected from 1,648 ASCs -- including 1,031 multispecialty ASCs and 617 single specialty ASCs -- representing every state.

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 Donna Slosburg, Executive Director, ASC Quality Collaboration at donnaslosburg@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.

Rate of patient falls in the ASC 0.145 per 1000 admissions

Represents the experience of 2,017,342 ASC admissions seen at 1,635 facilities between July 1 and September 30, 2019

The data trends for this measure over the last four quarters are presented below in both tabular and graphical 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.

Rate of patient burns 0.012 per 1000 admissions

Represents the experience of 2,018,184 ASC admissions seen at 1,636 facilities between July 1 and September 30, 2019

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.

Rate of hospital transfers/admissions 0.911 per 1000 admissions

Represents the experience of 2,019,051 admissions seen at 1,636 facilities between July 1 and September 30, 2019

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.

Rate of wrong site, side, patient, procedure, implant events 0.027 per 1000 admissions

Prophylactic IV Antibiotic Timing

Prevention of surgical wound infections is an important issue for patients having outpatient procedures or surgery. In cases where the physician has determined that an antibiotic should be given to help prevent a surgical wound infection, giving the antibiotic at the right time is important. Research indicates that antibiotics given too early, or after the surgery begins, are not as effective.

The percentage of ASC admissions having an order for an antibiotic to help prevent surgical wound infection that received the antibiotic in the appropriate timeframe is displayed below. Higher percentages are better.

Percentage of ASC admissions with antibiotics ordered who received antibiotics on time 99%

Represents the experience of 1,551,983 ASC admissions with antibiotics ordered seen at 1,250 facilities between July 1 and September 30, 2019

Appropriate Surgical Site Hair Removal

Prevention of surgical wound infections is an important issue for patients having outpatient procedures or surgery. In certain cases, properly preparing the patient for surgery requires the removal of body hair in the area where the surgery will be done. Removing body hair with electric clippers or hair removal cream reduces the likelihood of a surgical wound infection. Removing body hair by shaving with a razor may increase the likelihood of a surgical wound infection.

The percentage of ASC admissions that had body hair removed with electric clippers or hair removal cream is displayed below. Higher percentages are better.

Percentage of ASC admissions with appropriate surgical site hair removal 99%

Represents the experience of 933,264 ASC admissions with surgical site hair removal seen at 726 facilities between July 1 and September 30, 2019

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.

Percentage of eligible ASC patients with normothermia 98%

Represents the experience of 191,261 eligible ASC patients seen at 1,078 facilities between July 1 and September 30, 2019

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.
