- W3025360862 abstract "Background A section quality initiative was implemented beginning 2013 requiring positive pulmonary embolism (PE) results to be documented and communicated within 90 minutes of exam completion. The objective of this study is to evaluate the effect of this quality initiative on different intervals comprising the total patient processing time, namely the time from when the imaging exam was ordered to study completion interval, the time from study completion to positive PE result communication (TAT interval) or treatment initiation (TTT interval), the time from result communication to treatment initiation (TRCTI interval), and the total patient processing time (TPT interval). Methods This was a retrospective, single-institution, IRB-approved cohort study that included 830 patients with the diagnosis of acute PE confirmed by CT pulmonary angiography. A maximum of 10 positive exams per month were identified and analyzed over an 84-month period from January 2010 to December 2016. The following data were obtained: time when exam ordered, time of imaging study completion, time of report completion, time of result communication, time of treatment, type of treatment, and reasons for any treatment delay. Analysis was done by determining the mean time spent in various intervals, the cumulative relative frequency of interval completion, and the fraction of the entire patient processing time spent in each interval. Results Mean analysis demonstrated a decrease in all time intervals in the postpolicy period (ordered to study completion: Δ24.50%, p = 0.004; TAT: Δ23.91%, p < 0.001; TRCTI: Δ16.86%, p = 0.031; TTT: Δ17.40%, p = 0.005; TPT: Δ15.94%, p = 0.002). Cumulative relative frequency analysis demonstrated a higher rate of interval completion in the postpolicy period (TAT: p < 0.001; TRCTI: p = 0.007; TPT: p = 0.025). Interval fraction analysis demonstrated changes in the fraction of processing time spent in varying intervals (TAT: −Δ14.42%, p = 0.002; TRCTI: +Δ17.65%, p = 0.001). Conclusion Total patient processing time decreased after the policy implementation with a more significant decrease in TAT compared to other intervals. Radiologic processing time does not appear to be the rate-limiting step in total patient processing time.
