AT THE ACS NSQIP NATIONAL CONFERENCE
CHICAGO (FRONTLINE MEDICAL NEWS) – A novel effort to change the prevailing culture toward overuse of catheters in surgical patients appears to be paying off for one Midwestern hospital.
The goal was to decrease catheter utilization by 5%, but 6 months after implementation, the number of catheters placed per day in the operating room in surgeries lasting less than 3 hours declined 9% (mean 14.2/day vs. 12.9/day) and overall catheter utilization in these short cases by 12% (mean 23.7% vs. 20.6%).
Removal of catheters in the OR after surgery decreased by 15% (18.3% vs. 21%), Dr. Anthony D. Yang, of Northwestern Memorial Hospital, reported at the American College of Surgeons (ACS)/National Surgical Quality Improvement Program (NSQIP) National Conference.
Catheter-associated urinary tract infection (CAUTI) rates before the intervention put the Chicago-based hospital in the bottom 10% of ACS NSQIP hospitals.
Post-intervention, the number of CAUTIs in patients whose catheters were inserted in the OR declined 89% from a mean of 2.75 to 0.3 per month. In 4 out of 6 post-intervention months, no CAUTIs were reported, Dr. Yang observed.
Efforts to improve CAUTIs typically focus on removing catheters in surgical patients promptly after transfer to the floor, but the assembled multidisciplinary team chose the less-studied approach of decreasing overall utilization of catheters in the OR.
Using the DMAIC (Define, Measure, Analyze, Improve and Control) method of process improvement, the team identified and instituted two major interventions. First, all catheters have to be inserted with a two-person technique to identify previously unnoticed breaks in sterile technique. Second, OR staff routinely address the necessity for catheters with the surgical team at the beginning of the procedure and with the attending surgeon in the OR before the end of surgery in all cases.
To help change culture, educational programs were instituted with all perioperative services staff and house-staff physicians in all surgical departments, awareness was raised about the project and its justification, and the intervention was mandated to permit tracking.
A total of 465 catheters were inserted in the OR in cases less than 3 hours in the month prior to the intervention, compared with 391, 348, 409, 387, 382, and 427, respectively, in the first six months after the intervention, team leader Dr. Yang , with the hospital’s department of surgery and surgical oncology, said.
Adherence to the two-person sterile technique for OR catheter placement was 80% in the first month, reached 100% for the second and third months, but dropped to around 70% for months four through six. Data for the latter months was fed back to OR staff with encouragement to redouble efforts and increase compliance. It’s thought the problem is actually with documentation because at the time, the fields to document two-person technique in the electronic medical record were not required to be filled in before closing the file, he said.
Compliance with catheter status with the attending surgeon at sign-out was 88% in the first month, dipped slightly in months 2 and 3, and reached and has been maintained at about 85% in months 4 through 6.
“With any intervention it is expected to see periodic decreases in performance,” Dr. Yang said in an interview. “This is why using the DMAIC method becomes important, because the Control part of the methodology calls for continuously monitoring for drops in performance and includes a plan to respond to them. In our plan, the Control plan was to feedback data to the OR staff as the initial step.”
Future steps are to utilize the hospital’s Enterprise Data Warehouse report for monthly performance audits to identify any problem areas, develop a detailed Control plan and consensus criteria for catheter insertion in short cases, and to continue to provide feedback data to relevant stakeholders.
