Five hundred routine preemployment urine toxicology examinations were performed on prospective hospital employees in 1981. Thirty-three (6.6%) examinations were positive for one or more of either Valium, barbiturates, amphetamines, phencyclidine or opiates. Only 13 (2.6%) were confirmed to be positive. Of those with confirmed positive results, only one applicant was denied employment. Significantly, that case would have been suspected during the clinical preemployment examination. These results indicate that including a routine urine toxicology screen in a preemployment examination may not be cost-effective.
1981年，对预期的医院员工进行了500次常规入职前尿液毒理学检查。33次（6.6%）检查对安定、巴比妥类药物、安非他明、苯环己哌啶或鸦片制剂中的一种或多种呈阳性。只有13次（2.6%）被确认为阳性。在那些结果被确认呈阳性的人中，只有一名申请人被拒绝录用。值得注意的是，该病例在临床入职前检查中就可能已被怀疑。这些结果表明，在入职前检查中纳入常规尿液毒理学筛查可能不具有成本效益。
