SDI values range from 0 (no distress\/prosperous) to 100 (highest distress). This study investigated the association between SDI and lumbar spine surgery outcomes.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>METHODS<\/jats:title>\n                    <jats:p>A retrospective cross-sectional study was performed using electronic health record data from a multihospital academic health system from 2017 to 2024. Eligible patients included adults who underwent lumbar fusion or decompression alone. The primary exposure of interest was the binary SDI (low distress [SDI &lt; 50] vs high distress [SDI \u2265 50 and \u2264 100]). SDI was associated with the patient\u2019s zip code of residence. The associations between SDI category and pain reduction, physical function improvement, length of stay, and 30-day readmission were examined. Both unadjusted and adjusted regression models were created. Adjusted models included the following covariates: age, comorbidities, race, insurance, and surgery type. Multiple imputation by chained equations was used to impute missing values.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>RESULTS<\/jats:title>\n                    <jats:p>The total sample included 7598 patients with 5139 in the low-SDI group and 2459 in the high-SDI group. SDI category was not significantly associated with the likelihood of pain reduction or physical function improvement after surgery. In the adjusted model, residence in a high-SDI area was significantly associated with extended length of stay (OR 1.21, 95% CI 1.07\u20131.36, p = 0.002). In the unadjusted model, patients from high-SDI areas were significantly more likely to experience 30-day readmission (OR 1.35, 95% CI 1.07\u20131.71, p = 0.01). In the adjusted model, this association was no longer statistically significant (OR 1.00, 95% CI 0.74\u20131.36, p \u2265 0.99).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>CONCLUSIONS<\/jats:title>\n                    <jats:p>Patients from high-SDI areas had similar pain and physical function outcomes compared to patients from low-SDI areas after lumbar spine surgery.
