在许多司法管辖区，救护车调度数据以电子方式整理，并广泛涉及社区。因此，它们可能有助于综合征监测和早期识别新出现的传染病。本研究评估救护车调度数据是否适用于流感监测。比较1997-2005年澳大利亚墨尔本救护车调度数据的时间序列与流感样疾病（ILI）的现场服务和全科医生哨点监测数据。所有数据以1周为周期汇总，与GP哨点监测系统的数据收集周期相对应，以GP哨点监测系统作为参考系统。研究人员比较了每1000次救护车调度中被分类为呼吸或呼吸问题的救护车调度率，与每1000次门诊呼叫中流感或流感的呼叫率，以及哨点全科医生每1000名病人的流感发病率。救护车数据的信号使用对数似然比CUSUM生成，这是一种适合于监测的连续监测方法。救护车调度数据显示的季节性趋势与在当地服务监测和全科医生哨点系统中观察到的相似，并确定了流感季节性活动高于预期的年份（1998年和2003年）和流行年（1997年）。然而，在流感活动最少的月份，被分类为呼吸或呼吸问题的救护车呼叫的基线率很高（每1000次呼叫90-100次）。救护车调度数据具有监测综合征的潜力，但由于背景噪音高，因此不具有确定性，需要进行校准以适应特定的当地情况。
Ambulance dispatch data are collated electronically in many jurisdictions and have a wide reach into the community. They may therefore be useful for syndromic surveillance and early recognition of emerging infectious diseases. This study assessed whether ambulance dispatch data are suitable for influenza surveillance. Comparison of a time series of ambulance dispatch data from Melbourne, Australia for the years 1997–2005 with locum service and general practice (GP) sentinel surveillance data for influenza-like illness (ILI). All data were aggregated into 1-week periods, corresponding to the data collection period used in the GP sentinel surveillance system, which was used as the reference system. Rates of ambulance dispatches classified to respiratory or breathing problems per 1000 total dispatches were compared with rates of callouts for flu or influenza per 1000 locum calls, and rates of ILI per 1000 patients from the sentinel GPs. Signals from the ambulance data were generated using the log likelihood ratio CUSUM, a method of continuous monitoring suitable for surveillance. The ambulance dispatch data displayed seasonal trends that were similar to those observed in locum service surveillance and GP sentinel systems, and identified the years with higher-than-expected seasonal ILI activity (1998 and 2003) and the epidemic year (1997). However, there was a high baseline rate of ambulance calls classified to respiratory or breathing problems (90–100 per 1000 calls) in months where there was minimal influenza activity. Ambulance dispatch data have potential for syndromic surveillance, but because of the high background noise are not definitive and would need to be calibrated to suit particular local circumstances.
