    A Quality Improvement Initiative to Reduce Unnecessary Screening Chest Radiographs in a Pediatric ICU
    (American Association of Respiratory Care, 2023) Malin, Stefan W.; Maue, Danielle K.; Cater, Daniel T.; Ealy, Aimee R.; McCallister, Anne E.; Valentine, Kevin M.; Abu-Sultaneh, Samer M.; Pediatrics, School of Medicine
    Background: The Critical Care Societies Collaborative included not ordering diagnostic tests at regular intervals as one of their Choosing Wisely initiatives. A reduction in unnecessary chest radiographs (CXRs) can help reduce exposure to radiation and eliminate health care waste. We aimed to reduce daily screening CXRs in a pediatric ICU (PICU) by 20% from baseline within 4 months of implementation of CXR criteria. Methods: All intubated patients in the PICU were included in this quality improvement project. Patients with tracheostomies were excluded. We developed criteria delineating which patients were most likely to benefit from a daily screening CXR, and these criteria were discussed for each patient on rounds. Patients on extracorporeal membrane oxygenation, on high-frequency oscillatory ventilation, or on high support on conventional mechanical ventilation were included as needing a daily screening CXR. We tracked the percentage of intubated subjects receiving a screening CXR as an outcome measure. Unplanned extubations and the number of non-screening CXRs per intubated subject were followed as balancing measures. Results: The percentage of intubated subjects receiving a daily screening CXR was reduced from 79% to 31%. There was no increase in frequency of unplanned extubations or number of non-screening CXRs. With an estimated subject charge of roughly $270 and hospital cost of $54 per CXR, this project led to an estimated $300,000 in patient charge savings and $60,000 in hospital cost savings. Conclusions: Adopting criteria to delineate which patients are most likely to benefit from screening CXRs can lead to a reduction in the percentage of intubated patients receiving screening CXRs without appearing to increase harm.

    A Quality Improvement Initiative to Reduce Unneeded Screening Chest Radiographs in a Pediatric Cardiovascular ICU
    (Daedalus Enterprises, 2023) Malin, Stefan W.; McCallister, Anne E.; Abu-Sultaneh, Samer M.; Valentine, Kevin M.; Pediatrics, School of Medicine
    Background: Adult critical care and radiographical societies have recommended changing practice from routine screening radiographs to on-demand chest radiographs (CXRs) for stable mechanically ventilated adult patients. There are no similar recommendations for patients in the pediatric ICU. Reducing the frequency with which unneeded CXRs are obtained can decrease radiation exposure and reduce waste, a substantial contributor to rising health care costs. We aimed to reduce unneeded daily screening CXRs in a pediatric cardiovascular ICU (CICU) by 20% in 6 months. Methods: Criteria delineating which subjects in the CICU required daily screening CXRs were created and added to the daily rounding sheet for discussion for each subject. The primary goal of this study was to reduce CXRs in mechanically ventilated subjects as our previous practice had been to order daily CXRs. Respiratory therapists increased the frequency of evaluating and documenting endotracheal tube positioning prior to the initiation of this project. The outcome measure was the percentage subjects who received a daily screening CXR. The ratio of daily screening CXRs to the number of total CXRs ordered and unplanned extubations were followed as balancing measures. Results: The number of subjects who received a daily screening CXR decreased from a baseline of 67% to 44% over the course of this project. There was no change in the ratio of daily screening CXRs to the number of total CXRs ordered or an increase in unplanned extubations. With an estimated cost of $268 per CXR, a reduction of 33% in routine screening CXRs saves an estimated $250,000 annually. Conclusions: A decrease in daily screening CXRs can be sustained through the development of specific criteria to determine which patients need screening radiographs. This can be achieved without an increase in CXRs obtained at other times throughout the day or an increase in unplanned extubations. This eliminates unneeded health care expenditures, improves resource allocation for radiology technicians, and decreases disruptive interventions for patients.

    Fluid Accumulation After Neonatal Congenital Cardiac Surgery; Clinical Implications and Outcomes
    (Elsevier, 2022) Bailly, David K.; Alten, Jeffrey A.; Gist, Katja M.; Mah, Kenneth E.; Kwiatkowski, David M.; Valentine, Kevin M.; Diddle, J. Wesley; Tadphale, Sachin; Clarke, Shanelle; Selewski, David T.; Banerjee, Mousumi; Reichle, Garrett; Lin, Paul; Gaies, Michael; Blinder, Joshua J.; Pediatrics, School of Medicine
    BACKGROUND To determine the association between fluid balance metrics and mortality and other postoperative outcomes after neonatal cardiac surgery in a contemporary multi-center cohort. METHODS Observational cohort study across 22 hospitals in neonates (≤30 days) undergoing cardiac surgery. We explored overall % fluid overload, postoperative day 1 % fluid overload, peak % fluid overload, and time to first negative daily fluid balance. The primary outcome was in-hospital mortality. Secondary outcomes included postoperative duration of mechanical ventilation, and intensive care unit (ICU) and hospital length of stay. Multivariable logistic or negative binomial regression was used to determine independent associations between fluid overload variables and each outcome. RESULTS The cohort included 2223 patients. In-hospital mortality was 3.9% (n=87). Overall median peak % fluid overload was 4.9%, (interquartile range 0.4-10.5%). Peak % fluid overload and postoperative day 1 % fluid overload were not associated with primary or secondary outcomes. Hospital resource utilization increased on each successive day of not achieving a first negative daily fluid balance and was characterized by longer duration of mechanical ventilation (incidence rate ratio 1.11, 95% confidence interval 1.08-1.14, ICU length of stay (incidence rate ratio 1.08, 95% confidence interval 1.03-1.12), and hospital length of stay (incidence rate ratio 1.09, 95% confidence interval 1.05-1.13). CONCLUSIONS Time to first negative daily fluid balance, but not % fluid overload is associated with improved postoperative outcomes in neonates after cardiac surgery. Specific treatments to achieve an early negative fluid balance may decrease postoperative care durations.

    Reducing Unnecessary Nitric Oxide Use: A Hospital-Wide, Respiratory Therapist-Driven Quality Improvement Project
    (Daedalus Enterprises, 2021-01) Rogerson, Colin M.; Tori, Alvaro J.; Hole, Acrista J.; Summitt, Elizabeth; Allen, Jayme D.; Abu-Sultaneh, Samer; Valentine, Kevin M.; Pediatrics, School of Medicine
    BACKGROUND: We sought to evaluate the institutional use of inhaled nitric oxide (INO) and to create a pathway to reduce waste using the Institute for Healthcare Improvement's model for improvement. Our aim was to reduce the use of INO by 20% within 8 months. METHODS: This was a prospective, respiratory therapist-driven, quality improvement project. We implemented a hospital-wide INO utilization protocol that was developed by neonatology, pediatric critical care, cardiac critical care, and respiratory therapy. INO use and respiratory therapist input for protocol failures were derived from the electronic medical record and were used to generate improvement opportunities. Monthly total hospital use of INO (in hours) was used as the primary outcome measure. Median hourly use per subject (evaluated in groups of 7 subjects) was used as a secondary outcome measure. New sildenafil dosing was tabulated for pre- and post-INO weaning protocol intervention as a balancing measure. Subjects included all patients in the hospital who were given INO therapy during the specified timeframe. RESULTS: Hospital-wide total hours were reduced from 1,515 h/month to 930 h/month. This hospital-wide reduction of 39% equates to a cost-avoidance of approximately $912,000 per year based on 2018 costs of INO of $130 per hour. Median hours of INO per subject decreased from 88 h to 50 h. Sildenafil was started in 18 of 98 subjects (18%) in the pre-intervention period and in 12 of 109 subjects (11%) in the post-intervention period (P = .27). CONCLUSIONS: A hospital-wide, multi-professional initiative led to a reduction in unnecessary INO use, resulting in decreased subject exposure and associated cost avoidance.
