INTRODUCTION

The COVID-19 pandemic has profoundly impacted global healthcare systems, necessitating substantial shifts in patient care strategies. The pandemic's onset led to drastic operational changes in hospitals, including reduced bed capacity and staffing levels, which could have further influenced the mortality outcomes for geriatric patients. The study aimed to assess the impact of the COVID-19 pandemic on 1-year mortality rates of surgically treated geriatric hip fractures.

METHODS

This retrospective, single-center cohort study included 346 participants aged 65 and above who underwent surgical treatment for hip fractures. We compared mortality rates between the pre-COVID and COVID eras. Data included demographics, treatment, complications, and COVID-19 status. The independent samples test and Chi-square tests (or Fisher's exact test) were used for comparisons for era cohorts. Survival probabilities were assessed using Kaplan-Meier, while multivariate analysis identified mortality predictors.

RESULTS

175 patients were included in the pre-COVID era, and 171 patients were included in the COVID era. During the COVID era, the 30-day mortality rate was 11.7% (compared to 13.7% in the pre-COVID era, p = 0.573), and the 1-year mortality rate was 43.9% (compared to 49.1% in the pre-COVID era, p = 0.325). The overall 1-year mortality rate was 46.5%. Patients who underwent surgery within 48 hours had a higher 1-year survival rate (60.5%) compared to those with delayed surgery (51.2%), p = 0.031. Additionally, patients not admitted to the ICU had a higher 1-year survival rate (74.7%) than those who were admitted (44.9%), p < 0.001. 70.1% of the total deaths occurred within the first 90 days.

CONCLUSION

Elderly patients with hip fractures experienced high mortality rates before and during the pandemic. This study demonstrates that the 1-year mortality rates of geriatric hip fractures were not significantly affected by the pandemic. The findings emphasize the importance of pandemic preparedness and prompt surgeries and attentive ICU care in reducing mortality rates.
