 The patient is a 71-year-old widowed man who is seen regularly in the clinic for health maintenance and follow-up of his chronic insomnia and anxiety. He has regular prescriptions for triazolam (Halcion) and clonazepam (Klonopin) for these problems. Recently he has been reporting frequent episodes of losing his balance and falling, and eight weeks ago was hospitalized for a hip fracture sustained during one of these falls resulting in hip surgery. On this visit, he also complains of becoming increasingly confused.
