Study results presented at the 2016 ACS NSQIP Conference reveal how one Canadian hospital safety team implemented strategies to reduce the number of door openings during operations.
A Canadian hospital safety team determined there was too much traffic in and out of the operating room (OR) during total joint replacement procedures. They implemented several strategies to reduce traffic and found this may have contributed to a decrease in orthopedic surgical site infections (SSIs), according to study results presented today at the 2016 American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP®) Conference.
OR staff at Peace Arch Hospital (Fraser Health) in White Rock, British Columbia, launched a Comprehensive Unit-Based Program (CUSP) two years ago to improve patient and staff safety, said lead study author Susann Camus, MA, MPH. The team asked nurses, surgeons, anesthesiologists, and others who spend at least 60 percent of their time in the OR to complete a survey about what they thought caused patients harm and what to do to prevent it – and both nurse and surgeon survey participants said too much traffic in the OR caused harm. The hospital staff also learned from its NSQIP data that they had an excessively high rate of wound infections from orthopedic operations like knee and hip joint replacements, which are frequently performed in this hospital that serves an aging population. “Those SSIs were a high outlier and an area that needed urgent correction,” says Jason Forbes, MD, a general surgeon and Peace Arch’s NSQIP Surgeon Champion.
The team conducted the study over two days in November 2014, when two nursing students counted the number of door openings during nine total joint replacement operations and one revision procedure. They counted between 42 and 70 door openings per operation from incision time to joint capsule closure time. Operations averaged 75 minutes. Reasons for entering and exiting the OR during operations included retrieving charts, instruments or equipment, and taking a break.
The CUSP team instituted key changes including stopping all traffic in and out of the OR between total joint capsule opening and closure, communicating by phone, and increasing the use of templates to identify implant size prior to each operation, Camus says. A sign on the OR door also reminds staff to minimize traffic and asks them to record why they are entering the OR during an operation – and subsequent traffic audits taken every six months indicated a significant reduction in OR traffic from between 42 and 70 door openings to 3.2 door openings per case. This intervention may have contributed to a decrease in orthopedic SSIs from 2.8 percent to 2.1 percent since traffic control was implemented, according to the study authors, who also include Alexandra Kite, RN, CPN, Carline Tough, Paul Bennett, Shelley Dalzell, Gunter Heinz, Laura Holmes, and Natalie Koblizka.
Camus says the CUSP team shared their study results across Fraser Health’s 11 surgical sites – and that the project was significant because everyone on the team contributed to identifying and testing solutions to reduce OR traffic and cooperated to put solutions into place. The team will continue to conduct regular audits every six months. – and Forbes says they want to eventually expand these practices to other services, including general surgery, urology, and gynecology.
