To characterize patterns of Emergency Medical Technician (EMT) partner familiarity in three Emergency Medical Services (EMS) agencies. STUDY DESIGN/DATA SOURCES: We utilized a case study design and retrospective review of administrative data from three EMS agencies and 182 EMTs over 12 months. We used the Kruskal-Wallis test and Bonferroni corrected p-values to compare measures of partner familiarity. Measures included the annual mean number of partners, rate of partners per 10 shifts, mean shifts per EMT, and proportion of shifts worked with same partner. We standardized select measures by size of agency to account for a greater number of possible partnerships in larger agencies.
Across all agencies, the mean number of shifts worked annually by EMTs was (mean [SD]) 77.3 (59.8). The unstandardized mean number of EMT partnerships was 19.3 (12.4) and did not vary across EMS agencies after standardizing by agency size (p=.328). The unstandardized mean rate of EMT partnerships for every 10 shifts worked was 4.0 (2.7) and varied across agencies after standardizing (p<.001). The mean proportion of shifts worked with the same partner was 34.8 percent and varied across agencies (p<.001).
There was wide variation in select measures of EMT partner familiarity.
描述三个紧急医疗服务（EMS）机构中紧急医疗技术员（EMT）伙伴熟悉程度的模式。
研究设计/数据来源：我们采用案例研究设计，对三个 EMS 机构和 182 名 EMT 12 个月的行政数据进行回顾性审查。我们使用 Kruskal-Wallis 检验和 Bonferroni 校正的 p 值来比较伙伴熟悉程度的度量。措施包括年度平均伙伴数、每 10 次轮班的伙伴率、每名 EMT 的平均轮班数和与同一伙伴一起工作的轮班比例。我们通过机构规模对选定指标进行标准化，以解释在较大机构中可能存在更多的伙伴关系。
在所有机构中，EMTs 每年的平均轮班数（平均值[标准差]）为 77.3（59.8）。未经标准化的 EMT 伙伴关系平均数量为 19.3（12.4），在按机构规模标准化后，各 EMS 机构之间没有差异（p=.328）。未经标准化的每 10 次轮班的 EMT 伙伴关系平均比率为 4.0（2.7），在标准化后因机构而异（p<.001）。与同一伙伴一起工作的平均轮班比例为 34.8%，因机构而异（p<.001）。
在 EMT 伙伴熟悉程度的某些衡量标准上存在广泛差异。
