Correlates of low back pain outcomes in a community clinic.
Both governmental and private agencies have focused on the multiple outcome variables that may affect patient treatment. Our investigation examined treatment-independent outcome variables and correlates in patients with the sole complaint of low back pain. Treatment was conducted in an outpatient physical therapy clinic serving a rural/suburban Tennessee population.


METHODS
The review collected data on nine variables from 54 clinic records. The study group was 56% female, with ages for all subjects ranging from 26 to 84 years. Twenty-five patients carried private insurance, 14 were TennCare recipients (state Medicaid), 9 were covered by workers compensation, and 6 were Medicare based. The prescribed number of treatment sessions (Rx) varied from 1 to 3 visits to as many as 18.


RESULTS
The Rx was not related to sex, age, or payer type. The compliance index (Cx) (mean = 76.3%, range = 6% to 150%) was related to payer type (P < .02), but not related to sex, age, or Rx. TennCare patients had lower compliance levels (mean Cx = 51.1) than all other insurer groups combined (mean Cx = 85.0). Self-assessed improvement by the patient (Patient Status) was related to Cx (P < 0.005) but not sex, age, payer type, or Rx. Completion by the patient of long-term physical therapy goals as determined by the therapist was related to Cx (P < .03) and self-assessed patient status (P < .02), while disposition at discharge was associated with Cx, self-assessed patient status, and payer type (P < .001).


CONCLUSIONS
Compliance by patients significantly influences the outcome measures of self-assessed improvement, therapist assessment of achieving long-term treatment goals, and disposition at discharge. TennCare patients demonstrated both low compliance and poor outcome at discharge. These results suggest that the lower potential for positive treatment outcome may exist for the TennCare patient population.
