The goal of this observational study is to evaluate in elderly patients for the frequency of sarcopenia and its relationship with mortality in a university hospital.

The main questions it aims to answer are;

1. What is the frequency of sarcopenia in elderly patients at emergency department?
2. Is sarcopenia associated with mortality in an elderly patient admitted to the emergency department?

Inclusion Criteria:

1. Above the age of 65 admitted to the emergency department
2. Able to walk without support
3. No lower extremity fracture
4. No disease with neuromuscular involvement

Exclusion Criteria:

1. In the presence of a cerebrovascular event
2. Those in need of critical intervention when applying to the emergency department
3. Unconscious patients

Patients over 65 years of age, who can walk independently, who do not have lower extremity fractures or neuromuscular disease, will constitute the study population.

The mortality rate over the age of 65 was found to be 11%. Considering that the mortality rate with sarcopenia was 28%, it was found that 63 patients were required for the effect of sarcopenia on mortality with a 95% confidence interval and 0.5% margin of error. Since the incidence of sarcopenia in the emergency department was 33%, 200 patients were planned to be included in the study.
