Prognostic value of serum albumin and C-reactive protein levels in the elderly for assessing morbidity and mortality in a tertiary care center

ABSTRACT

Introduction: There is an increased population of elderly globally due to advancement of technology in health care. Elderly individuals are susceptible to various diseases, owing to deficits in nutrition or healthy lifestyle. Serum albumin and C‑reactive protein (CRP) are found to be sensitive to nutritional status as well as inflammation. This study is an attempt to analyze the prognostic value of CRP and serum albumin and analyze its usefulness as a prognostic marker in assessing morbidity and mortality in elderly patients. Methodology: One hundred patients above the age of 65 years and were admitted to the emergency care facilities of our tertiary care center were recruited for the study. Serum albumin and CRP estimation was done on the day of admission along with Charlson Comorbidity Index (CCI), and was follow-up till discharge. Statistical analysis was performed to evaluate relationship between the serum values and CCI scores. Results: It was observed that 83.3% (10/12) of deaths occurred in those with low serum albumin levels, and 91.6% (11/12) with high CRP levels. The hazard ratio shows a 6% increased probability of death with one unit increase in CRP, whereas a one unit increase in serum albumin value decrease the probability of death. Conclusion: The present study concludes that low serum albumin and high CRP levels at the time of admission in the elderly population are associated with high CCI scores, longer hospital stay, and increased risk of mortality, demanding their estimation in the elderly in emergency and acute care facilities.
