Site-specific variation is significant in all

domains of healthcare provision for the injured

child

C-collar placement

Transfers: aOR 3-8

Field response: aOR 3-5

FAST exam utilization

DVT prophylaxis

Pharmacologic: 0-11%

Mechanical: 0-19%

Limitations

Small sample size

Process-specific adjustments

Limited generalizability

Structure Process Outcome

Conclusions

Combining two existing datasets provides

detailed information that allows for

evaluation of of process of care metrics

for critically injured children across the

care continuum

With minimal additional infrastructure

With no additional FTE

Advice

Discovery consists not in seeking new

landscapes but in seeking with new eyes. –
