Outcome H How about linking b li ki errors to crash risk? Cues could reflect decision support, while assistance could reflect loss of independent operation of a vehicle. Can this be considered a surrogate measure for crash risk? 26 Driver Cues & Assistance VS. Outcome Consider the potential of documenting cues and assistance as flags to inspect naturalistic driving li i d i i data with ITS…that is my next task and presentation at RSS2011 13 9/9/2011 27 Limitations • Some missing or inaccurate data due to self report on intake forms t i t k f • Referral source not documented in relation to physician reporting or PennDOT pathway • Data collection only for clients of low‐tech adaptive equipment (No electronic control no adaptive equipment (No electronic control, no conversion vans) • Error analysis uses a custom coding scheme 28 Questions for You! • access for Driver Rehabilitation Specialists to p obtain traffic records? • variations of AMA ADReS Guidelines for physicians based on PCP vs Specialist referral? • failures vs disability results as validations for Driver Fitness Medical Guidelines publication? Driver Fitness, Medical Guidelines publication? • prior visit to ADP + Progressive Condition + variability of error rate as need for longitudinal data source in screening & prognosis of drivers? 14 9/9/2011 29 Acknowledgements • Amy Lane and Rosemarie Cooper Co‐PI’s on the study Adaptive Driving Adaptive Driving Program • NSF Quality of Life Technology Engineering Research Center • D Dr. Rory Cooper: R C Human Engineering Research Laboratories 30 Questions for Me? 15 9/9/2011 31 APPROACH Detailed Coding CODE Errors Lane Selection help with appropriate lane selection Knowing Signs Knowing Signs hesitant and slow @ intersection hesitant and slow @ intersection hesitant and stopped in middle of intersection missed stop sign trouble deciding right of way insufficient opportunity to observe Head Checks questionable check for traffic during lane changes lane change by mirrors only Mirrors required cues to check mirrors no mirror checks or unsatisfactory lane change without checking for traffic questionable check for traffic at intersections cued to make more mirror checks Speed Match poor speed matching to flow of traffic on hwy need to work on entry and exit for hwy Traffic Watch overyielding for merge of lane change 32 Disability Classification Disability Type Self‐Reported Terms Brain Injury TBI, brain injury, head injury, closed skull base fracture, post‐concussion b f i syndrome, brain aneurism, intracerebral hemorrhage, subarrachnoid hemorrhage, subdural hematoma Stroke Stroke, CVA, late eff/CV Dis Neurological Cerebellar ataxia, CP, spastic paraparesis, any neuropathy (ex.

Self‐Report Questionnaire Summary of practice 31 Driver Rehab Programs Medical Record Review Client demographics and outcomes 364 clients out of 7300 clients Self‐Report Questionnaire Duration of Driving and Accidents 589 clients over 3 year period 61% conducted pre‐drivers evaluations. Clinical tests used varied widely. All surveyed programs recommended behind‐the‐wheel evaluation upon passing pre‐drivers (clinical) evaluation. Better to assess than to predict Using Electronic Database… Allowed tracking of changes in client demographics Allowed tracking of changes in client demographics Helped support decision making: resource acquisition vs. referral to other program Basic data collection is good for business Found higher crash rate among hand control users than left foot accelerator users Contrary to clinicians opinion Building evidence can support more opportunities 17 9/9/2011 35 Referral Pathways & Referral Hit Ratios Hit Ratio = Nclients‐>Neg.Outcome | Referral Source Nclients|Referral Source 36 Referral Pathways & Referral Hit Ratios 0.2 02 18 9/9/2011 37 Referral Pathways & Referral Hit Ratios 0.2 02 38 Referral Pathways & Referral Hit Ratios 0.1 01 19 9/9/2011 39 Referral Pathways & Referral Hit Ratios 0.0 00 20
