Johns Hopkins study shows one of the deadliest hospital-acquired infections is preventable
Johns Hopkins Medicine May 25, 2017
In a recent paper published online in the journal Critical Care Medicine, researchers at the Johns Hopkins Armstrong Institute of Patient Safety and Quality led a study that demonstrated that health care providers can take steps to curb ventilator–associated events.
ÂWhen patients are sick, complications can happen, and, in some cases, health care–associated infections are thought to be inevitable, says Sean Berenholtz, MD, professor of anesthesiology and critical care medicine at the Johns Hopkins University School of Medicine and a faculty member in the Armstrong Institute. ÂThis is the largest study to date to show that these complications of mechanical ventilation, or ventilator associated events, are also preventable.Â
The study was conducted at 56 ICUs at 38 hospitals in Maryland and Pennsylvania from October 2012 to March 2015. The goal was to improve adherence with evidence–based practices, unit teamwork and safety culture. ÂUnfortunately, patients don't always receive the evidence–based therapies they should, says Berenholtz.
During the study period, the research team trained and coached quality improvement teams that included providers and staff at the designated sites, focusing on currently recommended interventions by the Society for Healthcare Epidemiology of America and the Society of Critical Care Medicine for patients on ventilators, including elevating the head of a patientÂs bed, suctioning a patientÂs mouth tube, performing oral care, such as tooth brushing and using chlorhexidine, a mouthwash that reduces dental plaque and treats gingivitis, and performing spontaneous awakening and breathing trials by reducing narcotics and sedatives and screening the patient for improvement. Teams were also trained to implement the Agency for Healthcare Research and QualityÂs (AHRQ) Comprehensive Unit–based Safety Program, or CUSP, on their units, a five–step culture change intervention that engages frontline health care staff members in preventing harm.
During the study period, the total number of ventilator–associated events in the ICUs decreased from 7.34 cases per 1,000 patient ventilator days to 4.58 cases after 24 months  a nearly 38 percent reduction. The number of infection–related ventilator–associated complications dropped from 3.15 to 1.56 cases, or more than 50 percent, and possible and probable ventilator–associated pneumonia cases dropped from 1.41 to .31 cases per 1,000 patient ventilator days, a 78 percent reduction.
ÂThese complications prolong the duration of mechanical ventilation, and they keep patients in the hospital longer, Berenholtz says. ÂThis, in turn, leads to higher complications, higher mortality, higher lengths of stay and higher costs. So decreasing these complications is a national priority and helps our patients recover sooner.Â
The Johns Hopkins researchers and their team have expanded this study to hospitals in all 50 states.
