PATIENT REPORTED OUTCOMES AND ASSOCIATED FACTORS FOLLOWING DECOMPRESSIVE LUMBAR SURGERY FOR DEGENERATIVE LUMBAR DISEASE, AT AABET HOSPITAL, ADDIS ABEBA, ETHIOPIA

Abstract

Abstract Introduction: Degenerative spine disease (DSD) is a progressive deterioration of the structures of the spine not related to acute trauma. Changes in the intervertebral disc are a major factor in the initiation of degenerative disc disease. DSD is managed conservatively and surgically if there is indication. Decompressive lumbar surgery is among the standard of care for patients having indication for surgery, with the major goal of treatment to increase health-related quality of life by reducing pain and disability. Lumbar decompressive surgery is among the common neurosurgical procedure in Ethiopia and also at AaBET hospital, but there is no study done at AaBET hospital about the outcomes and associated factors of these patients. The purpose of this study is to determine the Patient reported Outcomes and associated factors following Decompressive lumbar surgery for degenerative lumbar disease, at AaBET hospital. Objectives: The main objective of this study is to assess Patient reported Outcomes and associated factors following Decompressive lumbar surgery for degenerative lumbar disease. Methods: Hospital based cross-sectional study design was used. All Patients, for whom Decompressive lumbar surgery for degenerative lumbar disease was done at AaBET hospital, from January 1, 2020 to March 30, 2022 G.C, was included in the study. A structured questionnaire was used to collect data from the patient's chart and following phone interview. Data processing and analysis was done using SPSS-26 software. Descriptive statistics using frequency, mean, median, range and standard deviation was done and Multivariate regression analyses was used to determine association and p-value of less than 0.05 was considered statistically significant finally results presented by tables. Result: A total of 39 patients with mean age of 45.18 years were included in this study. Most of the patients were between the ages 0f 30-39 years. Male predominate 61.5% and all patients had low back pain at presentation. 76.9% of the respondents have satisfactory outcome and 23.1% of the respondents have poor patient reported outcome. Pre-operative working status and sphincter dysfunction were found to have statistically significant association with patient reported outcome based on the multivariable logistic regression. Conclusion: This study demonstrated that satisfactory patient reported outcome following decompressive lumbar surgery for degenerative lumbar disease is comparable with other studies. Pre-operative working status and sphincter dysfunction were found to have statistically significant association with patient reported outcome. A prospective study with a sizable sample size is required to assess the impact of the finding in this study on decision-making in the future.
