Background ContextThe patient experience of care as measured by the Hospital Consumer Assessment of Healthcare Providers and Systems (HCAHPS) survey is currently used to determine hospital reimbursement. The current literature inconsistently demonstrates an association between patient satisfaction and surgical outcomes.PurposeTo determine whether patient satisfaction with hospital experience is associated with better clinical outcomes in lumbar spine surgery.Study DesignA retrospective cohort study conducted at a single institution.Patient SampleA total of 249 patients who underwent lumbar spine surgery between 2013 and 2015 and completed the HCAHPS survey.Outcome MeasuresSelf-reported health status measures, including the EuroQol 5 Dimensions (EQ-5D), Pain Disability Questionnaire (PDQ), and visual analog score for back pain (VAS-BP).MethodsAll patients undergoing lumbar spine surgery between 2013 and 2015 who completed an HCAHPS survey were studied. Patients were excluded from the study if they had been diagnosed with spinal malignancy, scoliosis, or had less than 1 year of follow-up. Patients who selected a 9 or 10 overall hospital rating (OHR) on HCAHPS were placed in the satisfied group, and the remaining patients comprised the unsatisfied group. The primary outcomes of this study include patient-reported health status measures such as EQ-5D, PDQ, and VAS-BP. No funds were received in support of this study, and the authors report no conflict of interest-associated biases.ResultsOur study population consisted of 249 patients undergoing lumbar spine surgery. Of these, 197 (79%) patients selected an OHR of 9 or 10 on the HCAHPS survey and were included in the satisfied group. The only preoperative characteristics that differed significantly between the twogroups were gender, a diagnosis of degenerative disc disease (DDD), heavy preoperative narcotic use, and a diagnosis of chronic renal failure. At 1 year follow-up, no statistically significant differences in EQ-5D, PDQ, or VAS-BP were observed. After using multivariable linear regression models to assess the association between patient satisfaction and pre- to 1-year postoperative changes in health status measures, selecting a top-box OHR was not found to be significantly associated with change in either EQ-5D (beta=0.055 [95% confidence interval {CI}: -0.035 to 0.145]), PDQ (beta=-9.013 [95% CI: -23.782 to 5.755]), or VAS-BP (beta=-0.849 [95% CI: -2.125 to 0.426]). These results suggest high satisfaction with the hospital experience may not necessarily correlate with favorable clinical outcomes.ConclusionsTop-box OHR was not associated with pre- to 1-year postoperative improvement in EQ-5D, PDQ, and VAS-BP. Although the associations between high satisfaction and improvement in health status did not reach statistical significance, the best estimates from our multivariable models reflect greater clinical improvement with top-box satisfaction. Future studies should seek to investigate whether HCAHPS are a reliable indicator of quality care in lumbar spine surgery.Copyright © 2017 Elsevier Inc. All rights reserved.
