Is law enforcement of drug-impaired driving cost-efficient?
The applied methodology for CBA has involved a simplistic behavioural response to enforcement increase and control efficiency. Although this methodology should be developed further, it is clearly indicated that the cost-efficiency of increased law enforcement of drug driving offences is dependent on the baseline situation of drug-use in traffic and on the current level of enforcement, as well as the RR and prevalence of drugs in road traffic.
ANCA are useful as markers for UC and colonic localization in CD. Definition of the antigenic specificities of ANCA in inflammatory bowel disease does not significantly contribute to their clinical significance.
