OBJECTIVE: To describe the expectations that patients and their physicians
have for outcomes after surgical treatment for sciatica and to examine the
associations between expectations and outcomes.
DESIGN:Prospective cohort study.
SETTING/PATIENTS: We recruited 273 patients, from the offices of orthopedic
surgeons, neurosurgeons, and occupational medicine physicians in Maine, wh
o had diskectomy for sciatica,
MEASUREMENTS AND MAIN RESULTS: Patients' and physicians' expectations were
measured before surgery. Satisfaction with care and changes in symptoms and
functional status were measured 12 months after surgery, More patients who
expected a shorter recovery time after surgery were "delighted," "pleased,
" or "mostly satisfied" with their outcomes 12 months after surgery than pa
tients who expected a longer recovery time (odds ratio [OR] 2.2; 95% confid
ence interval [CI] 1.1, 4.4). Also, more patients who preferred surgery aft
er learning that sciatica could get better without surgery had good symptom
scores 12 months after surgery than patients who did not prefer surgery (O
R 2.9; 95% CI 1.2, 7.0). When physicians predicted a "great deal of improve
ment" after surgery, 39% of patients were not satisfied with their outcomes
and 25% said their symptoms had not improved,
CONCLUSIONS: More patients with favorable expectations about surgery had go
od outcomes than patients with unfavorable expectations. Physicians' expect
ations were overly optimistic. Patient expectations appear to be important
predictors of outcomes, and eliciting them may help physicians identify pat
ients more likely to benefit from diskectomy for sciatica.
