title: Managing nonspecific low back pain: do nonclinical patient characteristics matter?
abstract: METHODS
  A fully blocked experimental design using clinical vignettes to query primary care physicians on prescription for management of acute nonspecific low back pain.
  
  
  OBJECTIVE
  To identify how nonclinical patient factors, specifically sex, patient presentation, and socioeconomic status, influence physician treatment recommendations for assessing and treating acute nonspecific low back pain.
  
  
  BACKGROUND
  Adherence to evidence-based practice guidelines for nonspecific low back pain remains inconsistent. Therefore, it is important to understand what factors guide physician management of these cases.
  
  
  METHODS
  One vignette and questionnaire was distributed to primary care and emergency department clinical physicians during meetings at five teaching hospitals. The questionnaire asked for diagnostic and treatment recommendations including specific tests, medications, therapeutic procedures, activity, referral to other services, and patient education for the case represented in the vignette.
  
  
  RESULTS
  Subjects included 284 physicians and approximately 75% had less than 5 years of clinical practice experience. Multivariate logistic regression showed seven significant associations of patient factors with treatment recommendations for acute nonspecific low back pain (one sex, two socioeconomic status, and four patient presentation; P < 0.05).
  
  
  CONCLUSIONS
  All three assessed nonclinical factors influenced physician decisions regarding diagnostic and treatment recommendations for acute nonspecific low back pain. Patient presentation, suggestive of a patient's emotional state, was shown to be the most influential.
