title: Facilitated "fast track" referral reduces time from abnormal screening mammogram to diagnosis.
abstract: BACKGROUND
  The Screening Mammography Program of British Columbia (SMPBC) implemented voluntary, facilitated referral to diagnostic imaging ("Fast Track") after testing 5 interventions to reduce time from an abnormal screening mammogram to diagnosis. The purpose of this study was to compare time intervals for patients evaluated through the Fast Track process with patients who were not.
  
  
  METHODS
  Data were extracted from the SMPBC database for women with abnormal screens conducted from January 1, 2003 to June 30, 2005 (N = 40,292). After exclusions, 39,607 screens were analyzed. Median and 90th percentile times were calculated from abnormal screen to diagnosis and for three subintervals: abnormal screen to notification, notification to first assessment, and first assessment to diagnosis.
  
  
  RESULTS
  One third of abnormal screens were investigated through Fast Track imaging facilities. Overall, the median time from abnormal screen to diagnosis was 8 days faster for Fast Track compared with non-Fast Track. There was no clinically significant difference in time from abnormal screen to notification. The median time from notification to first assessment was 1.1 weeks (Fast Track) compared with 2.4 weeks (non-Fast Track), a reduction of 9 days or 54% in the interval targeted by the Fast Track strategy. The time interval distribution from first assessment to diagnosis was significantly different only for those having a core biopsy (average 3 days faster for Fast Track).
  
  
  CONCLUSIONS
  Facilitated referral to diagnostic imaging reduces average time from notification of abnormal screen to first assessment by more than half. Additional strategies are needed to address diagnostic investigation beyond initial imaging procedures.
