Culture Ordering for Patients with New-onset Fever: A Survey of Pediatric Intensive Care Unit Clinician Practices.

ABSTRACT:

Introduction

Accurate assessment of infection in critically ill patients is vital to their care. Both indiscretion and under-utilization of diagnostic microbiology testing can contribute to inappropriate antibiotic administration or delays in diagnosis. However, indiscretion in diagnostic microbiology cultures may also lead to unnecessary tests that, if false-positive, would incur additional costs and unhelpful evaluations. This quality improvement project objective was to assess pediatric intensive care unit (PICU) clinicians' attitudes and practices around the microbiology work-up for patients with new-onset fever.

Methods

We developed and conducted a self-administered electronic survey of PICU clinicians at a single institution. The survey included 7 common clinical vignettes of PICU patients with new-onset fever and asked participants whether they would obtain central line blood cultures, peripheral blood cultures, respiratory aspirate cultures, cerebrospinal fluid cultures, urine cultures, and/or urinalyses.

Results

Forty-seven of 54 clinicians (87%) completed the survey. Diagnostic specimen ordering practices were notably heterogeneous. Respondents unanimously favored a decision-support algorithm to guide culture specimen ordering practices for PICU patients with fever (100%, N = 47). A majority (91.5%, N = 43) indicated that a decision-support algorithm would be a means to align PICU and consulting care teams when ordering culture specimens for patients with fever.

Conclusion

This survey revealed variability of diagnostic specimen ordering practices for patients with new fever, supporting an opportunity to standardize practices. Clinicians favored a decision-support tool and thought that it would help align patient management between clinical team members. The results will be used to inform future diagnostic stewardship efforts.

Project description:The culture of sedation and immobilization in the pediatric intensive care unit (PICU) is associated with PICU-acquired weakness, delirium, and poor functional, neurocognitive and psychosocial outcomes. A structured approach to introducing physical activity, as early as possible after PICU admission, may prevent these complications and optimize the holistic outcomes of critically ill children. Changing culture and introducing new clinical practice in PICU is complex, but can be approached systematically, using a "nuts and bolts" approach targeting the basic, practical considerations and essential required elements or components. Extending the construction analogy, this article reviews the relevant literature to describe the essential elements required to build and sustain a successful and safe early mobility program in the PICU. Effective early mobilization requires individual patient assessment and goal setting, using a collaborative inter-disciplinary, patient- and family-centered approach, to ensure mobility goals and physical activities are appropriate for the patient's age, condition/s, premorbid function, strength, endurance and developmental level. Early mobility activities for the pediatric age spectrum include active or active-assisted range of motion exercises, neurodevelopmental play, use of mobility devices, in-bed exercises, transfers, sitting or standing tolerance, crawling, pre-gait activities, ambulation and activities of daily living, with a focus on play as function. Although there are few complete contraindications to early mobilization, appropriate precautions and preparation should be taken to mitigate potential safety concerns. Although there are many perceived barriers to early mobilization in the PICU, at the level of patient, provider, institution and knowledge translation; these are not objectively associated with increased risk during mobilization and can be overcome through an engaged process of practice change by all members of the interprofessional clinical team. Early mobility programs could be initiated in PICU as systematic quality improvement initiatives, with established processes to optimize structural, process and system elements and to provide continual feedback, measurement, benchmarking and collaboration; to ultimately impact on measurable patient outcomes. Early, graded, and individually prescribed mobilization should be considered as part of the standard PICU "package of care" for all critically ill and injured children, in order to improve their functional status and quality of life after PICU discharge.
