The study also reported that an average of 18-28 percent of tests, referrals, procedures and consultations and around 13 percent of hospitalizations were ordered due to defensive reasons.
The study consisted of about 900 physicians in Massachusetts and was conducted between Nov. 2007 and Apr. 2008.
