Mortality and health-related quality of life following injuries and associated factors: a cohort study in Chandigarh, North India.

INTRODUCTION: Injuries are among the 10 leading causes of deaths worldwide. In recent years, the quality and reporting of injury mortality has improved but little or no data are available on the morbidity burden and impact of non-fatal injuries in India. This study evaluates health recovery status postinjury, identifying predictors of recovery in North India. METHODS: Prospective cohort study recruiting patients from one tertiary-level and two secondary-level hospitals in North India between April and June 2014 hospitalised due to any injury. Health-related quality of life was assessed at baseline and at 1-month, 2-month, 4-month and 12-month postinjury using the EuroQol five-dimensional (EQ-5D-5L) questionnaire. Multivariable linear regressions with generalised estimating equations were used to examine the relationship between sociodemographic and injury-related factors with the EQ-5D-5L single utility score and the visual analogue scale (VAS) score. RESULTS: A total of 2416 eligible patients aged ≥18 years were enrolled in the study. Of these, 2150 (74%) completed baseline and all four follow-up EQ-5D-5L questionnaires. Almost 7% (n=172) patients died by the first follow-up and the overall mortality at 12 months was 9% (n=176). Both EQ-5D-5L utility and VAS scores dropped significantly at 1-month postinjury but gradually improved at 2, 4 and 12 months. Severe injuries, defined as those requiring a hospital stay of ≥7 days, were associated with lower utility scores at 1-month, 2-month and 4-month follow-ups (p<0.001). CONCLUSION: This is the first study to examine health outcomes following injuries in India. The findings highlight the need to understand the social, psychological and biological factors influencing recovery outcomes. High mortality following discharge emphasises the need to invest in secondary and tertiary injury prevention in India.
