Abstract
OBJECTIVES: To evaluate factors associated with clinic follow-up after traumatic spinal injury (TSI) in Tanzania, focusing on demographic, injury-related and hospital variables. We hypothesised that socioeconomic and injury-specific factors would predict follow-up adherence. DESIGN: Retrospective observational cohort study. SETTING: Tertiary government referral centre for neurosurgery and orthopaedics in Dar es Salaam, Tanzania. PARTICIPANTS: 443 adults with TSI admitted between September 2016 and October 2021. Inclusion criteria included survival to discharge and availability of the discharge date. Patients with missing data were excluded. PRIMARY AND SECONDARY OUTCOME MEASURES: Primary outcomes were any clinic follow-up and 1-year follow-up post-discharge. Secondary outcome was time to loss of follow-up. Logistic regression was used to identify factors associated with follow-up, and Kaplan-Meier survival analysis assessed follow-up duration. RESULTS: Of 443 patients (85.8% male, median age 34 years), 52.4% returned for follow-up. Independent factors associated with return included private insurance (adjusted OR (aOR) 2.69, 95% CI 1.38 to 5.45, p=0.005), involvement in a road traffic accident (aOR 2.15, 95% CI 1.22 to 3.83, p=0.009), lumbar injuries (aOR 2.26, 95% CI 1.30 to 4.00, p=0.004), neurological improvement at discharge (aOR 3.52, 95% CI 1.72 to 7.64, p=0.001) and hospital stays shorter than 24 days (aOR 1.63, 95% CI 1.07 to 2.47, p=0.022). Among those who returned, only 25.4% completed 1 year of follow-up. Predictors of 1-year follow-up included being female (aOR 4.87, 95% CI 2.31 to 10.56, p<0.001) and having American Spinal Injury Association Impairment Scale B-D versus E at admission (aOR 2.49, 95% CI 1.10 to 6.00, p=0.034). Kaplan-Meier analysis revealed that only 13.3% remained in follow-up at 12 months. CONCLUSION: Follow-up after TSI in this low- and middle-income country setting is poor, with fewer than one in eight patients completing 1 year. Private insurance, injury mechanism, neurological improvement and female sex predicted follow-up. Targeted efforts are needed to improve long-term care engagement.
