RESUMO
Purpose: Managing pediatric patients requiring daily general anesthesia (GA) for radiation therapy (RT) in the setting of COVID-19 is complex, owing to the aerosolizing nature of GA procedures, the risk of cardiopulmonary complications for infected patients, and the treatment of immunocompromised oncology patients in a busy, densely populated radiation oncology clinic. Methods and Materials: We developed an institutional protocol to define procedures for COVID-19 testing and protection of patients, caregivers, and staff, hypothesizing that this protocol would allow patients requiring GA to be safely treated, minimizing COVID-19 transmission risk to both patients and staff, and at the same time maintaining pre-COVID-19 patient volumes. All patients underwent COVID-19 testing before their first treatment and thrice weekly during treatment. For patients who tested positive for COVID-19, RT was delivered in the last end-of-day treatment appointment. A negative pressure room was used for GA induction and recovery, and separate physician/nurse teams were designated for in-room versus out-of-room patient management. Results: Seventy-eight pediatric patients received RT under GA, versus 69 over the same prior year timeframe, and 2 patients received 2 courses of RT under GA, for a total of 80 courses. The mean age was 4.9 years (range, 0.5-19.0 years) and 41 of 78 (52.6%) were male. Two patients (2.6%) received 2 courses of RT under GA, establishing a total of 80 courses. The mean number of treatment fractions was 22.2 (range, 1-40). Two of 78 patients (2.6%) tested positive for COVID-19; both were asymptomatic. Both patients completed treatment as prescribed. Neither patient developed cardiopulmonary symptoms complicating anesthesia, and neither patient experienced grade 3+ acute radiation toxicity. Conclusions: With careful multidisciplinary planning to mitigate COVID-19 risk, pediatric RT with GA was carried out for a large patient volume without widespread infection and without increased toxic effects from either GA or RT.
RESUMO
BACKGROUND: Young children who undergo radiation therapy may require general anesthesia to remain still during weeks of radiation sessions. On a typical day at our hospital, an anesthesia team will care for 10 patients in the radiation therapy suite, and each patient will have multiple prior anesthetic records. Daily review of prior anesthesia records is important to maintain anesthetic consistency and to identify potential improvement, yet our electronic health record (EHR) made such review time-consuming and cumbersome. OBJECTIVES: This article aims to design a visual analytics interface that simultaneously displays data from multiple anesthesia encounters to support clinical consistency in medications and airway management. METHODS: Documentation from the EHR is available in the clinical data warehouse following daily backups. A visual analytics interface was built to aggregate important components of multiple anesthesia encounters in pediatric radiation oncology on a single screen. The application was embedded in the EHR's anesthesia module and updated daily. RESULTS: Each anesthesia encounter was represented by a vertical line with the date at the bottom of the screen. Each vertical line was divided into sections corresponding to the medications, type of airway device, type of radiation oncology procedure, days between treatments, and recovery score and time. Information about the medications, airways, and procedures was shown with icon legends. This layout enabled users to quickly see the key components of multiple anesthetics and make inferences between, for example, the medications used and the recovery score. CONCLUSION: The dashboard provides a high-level summary of all radiation therapy anesthesia records for children receiving recurrent treatments. In this clinical scenario, it is desirable to replicate an optimal anesthetic approach for daily or near-daily treatments or adjust the anesthetic based on observed patterns.
