Is it possible to predict the efficacy at discharge of inhospital rheumatology department management of disk-related sciatica? A study in 150 patients.
OBJECTIVE
To identify criteria for predicting the outcome at discharge in patients scheduled for inhospital treatment of disk-related sciatica.


METHODS
We studied 150 rheumatology department patients admitted for disk-related sciatica with a mean duration of 88 +/- 127 days to determine the impact on treatment outcomes of 50 parameters.


RESULTS
After complete bed and 2.2 +/- 1.1 epidural glucocorticoid injections during a mean hospital stay of 9.9 +/- 4.3 days, 80% of patients reported either complete or partial pain relief (19% and 61%, respectively). The remaining 20% reported little (9%) or no (11%) change. Surgery was performed in 13% of cases. A tighter straight-leg raising test angle was correlated with treatment failure (P = 0.01). Complete bed rest duration prior to admission was shorter in the 80% of responders (P = 0.036) than in the 20% of nonresponders; in the overall population, patients spent on average 64% +/- 33% of daytime hours in bed. Patient predictions about their own outcomes were unreliable (P = 0.926). Patients who believed strongly that sciatica requires surgical treatment were more likely to be nonresponders (P = 0.06), as were patients with a family history of surgically-treated sciatica (P = 0.055). Outcomes were not correlated with any of the other parameters studied, including sciatica duration (P = 0.13), bedrest duration prior to admission (P = 0.52; mean duration, 18 +/- 29 days), the specialty of the physicians seen, investigations done prior to admission, or a history of sciatica (noted in 65% of cases and treated surgically in 16%).


CONCLUSIONS
Eighty percent of patients benefited from their hospital stay. Patient opinions on the merits of nonsurgical and surgical treatments in their own case were not correlated with their own outcomes. A tight straight leg-raising test angle was correlated with a poorer outcome. Neither sciatica duration nor rest duration prior to admission had an influence on outcome. Absence of complete bed rest prior to admission was correlated with a greater likelihood of a therapeutic benefit from the hospital stay.
