Magnetic Resonance Imaging (MRI) can be a challenging examination, particularly for children. The aim of this Clinical Perspective is to outline early experiences, based upon a service evaluation (defined as an assessment of how well the intended aims are achieved), of the Playful Magnetic Resonance Imaging Simulator (PMRIS) (Domed, Lyon, France) in reducing the number of children requiring general anaesthetic (GA) in order to undergo Magnetic Resonance Imaging (MRI).
Baseline data from an audit of children undergoing MRI under GA in 2017 had previously been captured as part of the funding bid for the PMRIS. Estimation of costs associated with anaesthesia were made, then combined with the overall numbers of MRI under GA to estimate projected anaesthetic related cost-savings based on the reported effectiveness of the PMRIS. Once the PMRIS was in place, data were collected for children attending a Play Specialist supervised session. The number and age of children proceeding directly to MRI without requiring a GA was determined. The associated cost benefit was calculated and compared with the projections made in the initial funding bid.
Over a 7 month period 36 children, average age 6 years, age range 4 to 11 years, who had initially been triaged for MRI under GA, attended a Play Specialist led session on the PMRIS. Of these, 30, average age 6 years, age range 4 to 11 years proceeded directly to MRI without a GA. Based on the costings used for the initial funding bid, this equates to a gross cost-saving of £9,000 over 7 months.
This service evaluation shows a positive impact of Play Specialist sessions using the PMRIS with 30 out of 36 children having a successful awake MRI as a result. There are limitations to this evaluation, particularly that whilst all these children had been triaged for MRI under GA it cannot be known how many might have had an awake MRI with different preparation. Nevertheless, according to the local referral pathways these children would otherwise have had MRI under GA.
This service evaluation has shown that the number of GAs required for children having MRI has reduced for this particular service through the use of the PMRIS, with Play Specialist support, with associated reduction in risk and cost savings.
磁共振成像(MRI)对于儿童来说可能是一项具有挑战性的检查。本临床观点旨在概述基于服务评估(定义为评估既定目标的实现情况)的早期经验,即使用游乐磁共振成像模拟器(PMRIS)(法国里昂的多姆德)减少需要全身麻醉(GA)才能进行磁共振成像(MRI)的儿童数量。
先前在 2017 年 GA 下进行 MRI 的儿童的审计中已捕获了基线数据,这是 PMRIS 资助申请的一部分。对与麻醉相关的成本进行了估计,然后将其与 GA 下进行的 MRI 总数相结合,根据 PMRIS 的报告效果估计潜在的麻醉相关成本节约。一旦 PMRIS 到位,就会为参加专业游乐师监督课程的儿童收集数据。确定了无需 GA 即可直接进行 MRI 的儿童的数量和年龄。计算了相关的成本效益,并与初始资助申请中的预测进行了比较。
在 7 个月的时间里,36 名平均年龄为 6 岁(年龄范围为 4 至 11 岁)的儿童最初被分诊为 GA 下的 MRI,参加了专业游乐师领导的 PMRIS 课程。其中,30 名平均年龄为 6 岁(年龄范围为 4 至 11 岁)的儿童无需 GA 即可直接进行 MRI。根据初始资助申请中使用的成本计算,这在 7 个月内相当于 9000 英镑的总节省。
本服务评估显示,使用 PMRIS 进行专业游乐师课程对 36 名儿童中的 30 名产生了积极影响,这些儿童均成功进行了清醒 MRI。该评估存在局限性,特别是尽管所有这些儿童都被分诊为 GA 下的 MRI,但无法知道有多少儿童可能在不同的准备下进行了清醒 MRI。然而,根据当地转诊途径,这些儿童本来会在 GA 下进行 MRI。
本服务评估表明,通过使用 PMRIS 并辅以专业游乐师的支持,该特定服务中进行 MRI 的儿童所需的 GA 数量减少了,从而降低了风险和成本节约。
