Bryant and Harvey, 1999a

Prospective cohort

79 mild TBI (55 males, 24 females), 92 non-TBI patients (61 males, 31 females) 16–65 years old involved in MVAs, consecutively admitted into major trauma hospital for at least 1 day

Mild, defined as PTA for less than 24 h

PTSD diagnosed with CIDI at 6 mo

ISS greater in mild-TBI than in non-TBI group (9.28 vs 4.0; p < 0.001)

None

Head injury ascertained at time arrived at hospital from MVA

 

 

 

 

No significant difference in rates of PTSD between groups with mild TBI and no TBI (24%, n, 15; 25%, n, 18, respectively; p value not reported)

 

Good followup over 6-mo period

 

 

 

 

 

Limitations include lack of control for associated injuries, lack of assessment of duration of LOC on occurrence of PTSD

 

 

Patients ascertained sequentially over 10-mo period at hospital admission; all assessed at 1 mo; 63 mild TBI (80%), 71 non-TBI (77%) evaluated at 6 mo after trauma

 

 

 

 

 

Exclusions: drug or narcotic analgesia (except codeine) for first 4 weeks after injury, inability to answer questions, non-English-speaking
