Pediatric patients undergoing MRI often require general anesthesia, which may improve image quality but is associated with significant medical risk and economic cost. It has previously been shown that certified child life specialists using high-tech interventions (eg, MRI-compatible video goggles) significantly reduce the number of pediatric MRI patients who require sedation. Most imaging centers lack such technology, however, and it remains unclear whether simpler and less costly child life interventions may be equally effective in avoiding general anesthesia. The aim of this study was to assess the impact of requiring mandatory child life evaluation for all patients aged 5 to 18 years undergoing MRI before referral for general anesthesia. Inserting this simple step into the scheduling workflow significantly reduced the use of general anesthesia in this population: general anesthesia was required in 564 of 2,433 MRI cases during the 1-year baseline period compared with 484 of 2,526 cases during the 1-year intervention period (P < .01 by z test for proportions; absolute reduction, 4.0%; relative reduction, 14.8%). The authors estimate that instituting mandatory child life evaluation avoided the use of general anesthesia in approximately 102 patients during the intervention period. Further subgroup analysis revealed that avoidance of general anesthesia was highly significant in the 5- to 10-year-old age group, whereas those aged 11 to 18 years experienced only a trend toward modestly decreased use of general anesthesia. These results suggest that mandatory evaluation for standard child life interventions is a worthwhile step that can save many children from unnecessary exposure to the risks, cost, and inconvenience of general anesthesia.
接受磁共振成像(MRI)检查的儿科患者通常需要全身麻醉,这可能会提高图像质量,但会带来重大医疗风险和经济成本。此前已有研究表明,经过认证的儿童生活专家使用高科技干预措施(如与MRI兼容的视频护目镜)可显著减少需要镇静的儿科MRI患者数量。然而,大多数成像中心缺乏此类技术,尚不清楚更简单、成本更低的儿童生活干预措施在避免全身麻醉方面是否同样有效。本研究的目的是评估在将所有5至18岁接受MRI检查的患者转诊进行全身麻醉之前,要求进行强制性儿童生活评估的影响。在调度工作流程中加入这一简单步骤可显著减少该人群全身麻醉的使用:在为期1年的基线期内,2433例MRI病例中有564例需要全身麻醉,而在为期1年的干预期内,2526例病例中有484例需要全身麻醉(比例的z检验P <.01;绝对减少率为4.0%;相对减少率为14.8%)。作者估计,在干预期内,实施强制性儿童生活评估避免了约102例患者使用全身麻醉。进一步的亚组分析显示,在5至10岁年龄组中,避免全身麻醉的效果非常显著,而11至18岁的患者仅呈现全身麻醉使用略有减少的趋势。这些结果表明,对标准儿童生活干预措施进行强制性评估是一个值得采取的步骤,可以使许多儿童避免不必要地暴露于全身麻醉的风险、成本和不便之中。
