nv-HAP surveillance too time-consuming? Semi-automated may be easier than you think

In this episode, Phil and Martin talk to Dr Aline Wolfensberger, Senior Attending Physician, Department of Infectious Diseases and Hospital Epidemiology at University Hospital Zurich and a Senior Researcher at the Institute for Implementation Science in Health Care at the Univetsity of Zurich. We discuss a recent paper that has analysed a range of algorithms for detecting non-ventilator associated pneumonia (nvHAP) that have the potential for significantly reducing the surveillance burden. This work also demonstrated the value of an annual local hospital-wide point prevalence survey that provides data on which areas to target.
