Few studies have evaluated pre-hospital documentation quality. We retrospectively assessed emergency medical service (EMS) documentation of key logistic, physiologic, and mechanistic variables in motor vehicle accidents (MVAs).
Records from police, Emergency Medical Communication Centers (EMCC), ground and air ambulances were retrospectively collected for 189 MVAs involving 392 patients. Documentation of Glasgow Coma Scale (GCS), respiratory rate (RR), and systolic blood pressure (SBP) was classified as exact values, RTS categories, clinical descriptions enabling post-hoc inference of RTS categories, or missing. The distribution of values of exact versus inferred RTS categories were compared (Chi-square test for trend).
25% of ground and 11% of air ambulance records were unretrieveable. Patient name, birth date, and transport destination was documented in >96% of ambulance records and 81% of EMCC reports. Only 54% of patient encounter times were transmitted to the EMCC, but 77% were documented in ground and 96% in air ambulance records. Ground ambulance records documented exact values of GCS in 48% and SBP in 53% of cases, exact RR in 10%, and RR RTS categories in 54%. Clinical descriptions made post-hoc inference of RTS categories possible in another 49% of cases for GCS, 26% for RR, and 20% for SBP. Air ambulance records documented exact values of GCS in 89% and SBP in 84% of cases, exact RR in 7% and RR RTS categories in 80%. Overall, for lower RTS categories of GCS, RR and SBP the proportion of actual documented values to inferred values increased (All: p<0.001). Also, documentation of repeated assessment was more frequent for low RTS categories of GCS, RR, and SBP (All: p<0.001). Mechanism of injury was documented in 80% of cases by ground and 92% of cases by air ambulance.
EMS documentation of logistic and mechanistic variables was adequate. Patient physiology was frequently documented only as descriptive text. Our finding indicates a need for improved procedures, training, and tools for EMS documentation. Documentation is in itself a quality criterion for appropriate care and is crucial to trauma research.
很少有研究评估过院前记录的质量。我们回顾性评估了机动车事故(MVA)中关键的后勤、生理和机械变量的紧急医疗服务(EMS)记录。
回顾性收集了 189 起涉及 392 名患者的 MVA 中来自警察、紧急医疗通信中心(EMCC)、地面和空中救护车的记录。格拉斯哥昏迷评分(GCS)、呼吸频率(RR)和收缩压(SBP)的记录分为准确值、RTS 类别、能够事后推断 RTS 类别的临床描述或缺失。比较了准确值与推断的 RTS 类别值的分布(趋势卡方检验)。
25%的地面和 11%的空中救护车记录无法检索。超过 96%的救护车记录和 81%的 EMCC 报告记录了患者姓名、出生日期和转运目的地。只有 54%的患者接诊时间传输到 EMCC,但 77%记录在地面和 96%的空中救护车记录中。地面救护车记录在 48%的病例中记录了 GCS 的准确值,在 53%的病例中记录了 SBP 的准确值,在 10%的病例中记录了 RR 的准确值,在 54%的病例中记录了 RR 的 RTS 类别。在另外 49%的 GCS 病例、26%的 RR 病例和 20%的 SBP 病例中,通过临床描述可以事后推断 RTS 类别。空中救护车记录在 89%的病例中记录了 GCS 的准确值,在 84%的病例中记录了 SBP 的准确值,在 7%的病例中记录了 RR 的准确值,在 80%的病例中记录了 RR 的 RTS 类别。总体而言,对于 GCS、RR 和 SBP 的较低 RTS 类别,实际记录值与推断值的比例增加(全部:p<0.001)。此外,对于 GCS、RR 和 SBP 的较低 RTS 类别,重复评估的记录更为频繁(全部:p<0.001)。地面记录了 80%的病例的损伤机制,空中救护车记录了 92%的病例的损伤机制。
EMS 对后勤和机械变量的记录是充分的。患者的生理状况经常仅以描述性文本记录。我们的发现表明,需要改进 EMS 记录的程序、培训和工具。记录本身就是适当护理的质量标准,对创伤研究至关重要。
