Evaluation of Clinical Tool to Improve Adherence to Ventilator Management at UM

Background:

Respiratory Therapists (RTs) face challenges to provide high quality patient care including maintaining compliance with evidence-based practice protocols using lung protective ventilation (LPV) (tidal volume [VT] 4 to 8 ml predicted body weight and plateau pressure [Pplt] < 30 cm H2O), efficient communication during patient handoffs at shift changes and maintaining situational awareness amidst a high patient-to-clinician ratio and elevated acuity of patient care. Lung-protective ventilation (LPV) guidelines, initially published by ARDS Net and supported by the American Thoracic Society, Society of Critical Care Medicine and European Society of Intensive Care Medicine. LPV guidelines recommend use of low tidal volume (VT) (6 to 8 ml predicted body weight [PBW]) and inspiratory plateau pressure (Pplt) (≤ 30 cm H2O), proven to lower mortality in patients with adult respiratory distress syndrome (ARDS). However, several studies revealed that many clinicians and institutions are not effectively implementing LPV guidelines many years after their publication in the New England Journal of Medicine in 2000. Clinicians who are unable and/or unwilling to apply low VT and Pplt as defined above jeopardize patient safety and risk increased mortality. One study found only 27% of patients received low VT and Pplt within 48 hours of the onset of ARDS. It was also found that ". . . adoption of evidence-based mechanical ventilation in real world practice has been disturbingly slow."

Another daily challenge faced by an RRT is the transfer of vital patient information during shift changes. A less than optimal "patient hand-off" or communication of relevant patient care information during shift changes appears to be a major factor in preventable medical errors directly affecting patient safety. The primary objective of a patient hand-off is to provide accurate information about the patient's care, treatment and services, current condition and any recent or anticipated changes. While appearing to be relatively easy task, a comprehensive, high-quality patient hand-off can be a complex communication procedure. One study found that patient hand-off communication failures were responsible for 30% of malpractice claims in U.S. hospitals, resulting in 1,744 deaths and $1.7 billion in malpractice costs over five years. While the use of computerized patient handoff methods are likely to promote improved information transfer during patient hand-offs, there is a dearth of such easy-to-use, portable communication tools available for RTs. Other contributing factors adversely affecting patient hand-off communication appear to be unrecognized patient needs due to lack of accurate and real time electronic monitoring, task interruption from nuisance alarms and inability to quickly determine the correct clinical decision.

RT Assistant, a bedside, portable and hand-held electronic tool, was designed to help the RT with these challenges.

Goals:

Evaluate the clinical effectiveness of RT Assistant software for the following:

Maintaining patients according to established LPV guidelines for ventilator-dependent patients Maintaining established low oxygen therapy guidelines Improving patient shift report communication Collect baseline data from the selected ICU passively through the SickBay data aggregator, including percentage of time patients are within the LPV and oxygenation guidelines.

Collect baseline data on shift report quality by passively monitoring shift reports between RTs during the above baseline data collection Install the RT Assistant software, train participating RTs, and compare baseline data with the same data collected in the same ICU during the use of the RT Assistant software
