Interview Series: Dr. Meghan Dierks discusses how HVA increases hand-hygiene compliance
As we continue our interview series with today’s thought
leaders in patient safety, we spoke with Dr. Meghan Dierks, Assistant Professor, Harvard Medical School.
HVA (Hospital Video Auditing) is an innovative, non-intrusive, 24/7
auditing technology that significantly improves compliance with patient safety and hand washing practices and protocols
In structuring the HVA program at a surgery center in the southeastern United States, Dr. Dierks has witnessed compliance scores soar from 35% to 90%+... and even more striking, she's seen compliance rates remain there.
In what ways, and to meet which specific goals, is the healthcare facility using HVA?
"We
applied the technology to tackle a refractory problem in the healthcare
compliance arena--the very basic safety protocol revolving around
hand-hygiene and getting physicians to modify their safety behavior.
The technology was two-fold: first, it would provide us the ability to
collect highly reliable data and we hadn't been able to in the past.
And, second, by nature of collecting high-quality data and instilling a
feedback loop to relay that data to physicians practicing in that
environment we could achieve a behavioral change.
We had two goals, both of which were achieved through the use of HVA. First, we needed to be able to collect highly reliable data over a sustained period of time on hand hygiene behaviors--something that has been difficult to achieve using other strategies. Second, in order to achieve a behavioral change, we needed to be able to use this data to provide continuous performance feedback to the healthcare workers practicing in that environment."
What significant points of success and improvements have you witnessed from the surgery center using the technology?
"Prior
published studies have demonstrated that other efforts and
interventions--such as employing human observers or posting educational
signage--achieve short term, but not sustainable improvements in
compliance. HVA is a highly reliable data-collection technique that
enabled us to continuously measure performance over a long period of
time in the surgery center, and document positive movement toward an
established goal.
We are now reaching our sixth month of continuous measurement and feedback. Using HVA, we identified a relatively low baseline compliance rate of 38%. We provided weekly feedback, and over the next several weeks, saw dramatic improvements in compliance. This relatively high compliance rate has now been sustained in the 88%-98% range for six months. While the fact that we achieved 98% compliance within four weeks is remarkable, equally striking is the sustainability of the behavior change."
