The American College of Radiology recommends against routine portable chest radiographs (CXRs) to assess stable adult patients in the intensive care unit (ICU)1,2. In patients admitted to the pediatric ICU (PICU) evidence is limited, but small studies demonstrate the safety and impact of demand versus routine plus demand CXRs3.
Assess the acceptability and feasibility of reducing routine overnight CXRs on intubated patients at a single center PICU.
This quality improvement initiative was conducted in the PICU at Cincinnati Children’s Hospital Medical Center, a large quaternary care center medical-surgical ICU. The baseline rate of overnight CXRs per ventilator days was retrospectively measured over the prior calendar year. Provider expectations and attitudes around limiting overnight CXRs were gathered via a deidentified unit-wide survey. Rule-in patient criteria for limiting routine CXRs was established via departmental shared decision making.
Extracted electronic medical record data from January 2020 through November 2020 demonstrated an average of 1.5 overnight CXRs performed per ventilator day, with control limits ranging from 1.2 to 2.0 overnight CXRs per ventilator days without any significant seasonal variance [Figure 1]. The division-wide survey illustrated a readiness for change with most staff in agreement that all intubated patients do not require daily CXRs (82%). This agreement improved to 94% for patients > 40 kg and decreased to 59% for patients <10 kg [Figure 2]. The majority of providers were not opposed to increasing the interval between routine CXRs to >24 hours in those patients with stable or improving respiratory failure (82%), uncomplicated post-operative patients (91%), or patients intubated for neurological reasons (91%). In evaluating reasons for routine CXRs, 100% of critical care fellows and 86% of advanced practice nurses (APN) stated that they order daily CXRs due to cultural expectations as compared with only 7% of attending physicians [Figure 3].
Baseline rates of routine overnight CXRs are high and do not have significant seasonal fluctuation. There is broad practice acceptance and readiness to limit daily CXRs in patients >40kg and those without worsening respiratory failure. Motivation for ordering routine overnight CXRs on intubated patients varies greatly between critical care fellows and APN’s compared to attending physicians.
A high baseline rate of overnight CXRs juxtaposed with a high degree of readiness for change among PICU providers to reduce the use of routine CXRs on select intubated patients has primed the ICU to begin reduction of the rate of routine overnight CXRs. A multidisciplinary team has been formed and a key driver diagram has been created to assist the team in designing interventions for CXR reduction.
