Surgical indications do not forecast outcomes as well as they should. A review of the literature demonstrates a significant rate of overutilization of coronary angiography, coronary artery surgery, cardiac pacemaker insertion, upper gastrointestinal endoscopies, carotid endarterectomies, back surgery, and pain-relieving procedures. ⋯ Arguments against this approach and a plea for the development of tighter focused indications are presented. Implications for cost saving and reduction in suffering are discussed.

Over a 3 1/2-year period, a series of 20 chronic pain patients with back pain and with documented organic difficulties were treated by means of implanted spinal cord stimulation. Short-term treatment outcome was found to be significantly related to diagnosis, with single nerve root injury and mononeuropathy patients having better treatment outcomes than arachnoiditis patients with multiply injured nerve roots. Outcome was not related to the psychological evaluation, or age, sex, number of previous pain surgeries, pain location, the Minnesota Multiphasic Personality Inventory, or the Pain Assessment Index. Implications for patient selection are discussed.

Comparative Study
The subjective experience of acute pain. An assessment of the utility of 10 indices.
Sixty-nine postoperative patients indicated the severity of their pain using eight measures designed to assess pain intensity and two designed to measure pain affect. The utility and validity of the 10 measures were evaluated according to two criteria: (a) the magnitude of the relationship between each scale and a linear combination of the pain measures, and (b) relative rates of incorrect responding. ⋯ The 11-point Box Scale (BS-11) of pain intensity demonstrated the strongest relationship to a linear combination of all of the measures employed and was responded to correctly by each subject in the sample. All else being equal, these results suggest that the BS-11 scale may be the most useful clinical index of pain intensity among postoperative patients.

Fifty-eight patients undergoing cervical epidural injection of corticosteroids were followed for a 6-month period. Patients with 90% pain relief lasting 6 months were considered to have excellent results, those with greater than 50% pain relief lasting at least 6 weeks were considered to have good results, and all others were considered to have poor results. ⋯ Those patients with the diagnosis of cervical spondylosis and those with subacute cervical strain had statistically significantly (p less than 0.001, difference of proportions test) better results than patients with other diagnoses. The procedure of cervical epidural steroid injection may be most effective in patients with cervical degenerative joint disease as the etiology of their cervical pain.

The efficacy of self-hypnosis in the treatment of chronic pain was evaluated using a multiple baseline design for five patients referred to the Auckland Hospital Pain Clinic. Subjects were selected for high hypnotisability using the Stanford Hypnotic Clinical Scale. Daily records of pain intensity, sleep quality, medication requirements, and self-hypnosis practice were completed. ⋯ The patients showed an increase in personal locus of control and a shift of self-concept away from physical illness on the ISCRG. The results suggest that self-hypnosis can be a highly effective technique for some patients with chronic pain but not for all. Selection criteria and clinical factors other than hypnotisability need to be considered in further research, since even highly hypnotisable subjects may derive limited benefit from self-hypnosis.
