The Relationship Between CRP Levels and Hospitalization, Discharge, Readmission and Mortality Rates of Geriatric Patients Presenting to the Emergency Department

Abstract

Aim: This study aims to investigate the association between Creactive protein (CRP) levels and outcomes such as hospitalization, discharge, readmission, and mortality in geriatric patients (aged 65 and over) presenting to the emergency department for nontraumatic reasons. Material and Methods: CRP levels were retrospectively analyzed from blood tests taken during routine diagnostic and therapeutic processes for patients over 65 years of age who presented to the emergency department of a secondary state hospital for non-traumatic reasons between January 1, 2023, and June 30, 2023. Patients were categorized into five CRP level groups (5-50 mg/L, 51-100 mg/L, etc.) and evaluated for their medical history, complaints, hospitalization status, consultation requests, and mortality. Results: Patients with CRP levels between 5-100 mg/L were more frequently diagnosed with non-infective causes, while CRP levels over 101 mg/L were predominantly associated with infective causes. A statistically significant association was found between elevated CRP levels and increased rates of hospitalization and mortality (p < 0.001). Conclusion: A significant relationship was observed between CRP levels and the rates of consultation and hospitalization in geriatric patients admitted to the emergency department for nontraumatic reasons. Additionally, elevated CRP levels were strongly associated with increased mortality rates among hospitalized patients. The findings indicate that CRP levels exceeding 101 mg/L were associated with infectious diagnoses and poor outcomes, highlighting the need for close monitoring of these patients. CRP levels should be considered an integral part of the decision-making process in geriatric emergency patients

Acil Servise Başvuran Geriatrik Hastaların CRP Düzeyi ile Hastaneye Yatış, Taburculuk, Yeniden Başvuru, Mortalite Oranları Arasındaki İlişki

Abstract

Amaç: Bu çalışma, travmatik olmayan sebeplerle acil servise başvuran 65 yaş ve üzeri geriatrik hastalarda C-reaktif protein (CRP) düzeyleri ile hastaneye yatış, taburculuk, yeniden başvuru ve mortalite gibi sonuçlar arasındaki ilişkiyi araştırmayı amaçlamaktadır. Gereç ve Yöntemler: 1 Ocak 2023 ile 30 Haziran 2023 tarihleri arasında, travmatik olmayan sebeplerle bir ikinci basamak devlet hastanesi acil servisine başvuran 65 yaş üstü hastalardan rutin tanı ve tedavi süreçleri sırasında alınan kan testlerinden elde edilen CRP düzeyleri retrospektif olarak analiz edilmiştir. Hastalar beş farklı CRP düzey grubuna (5-50 mg/L, 51-100 mg/L vb.) ayrılmış ve tıbbi geçmişleri, şikayetleri, hastaneye yatış durumları, konsültasyon talepleri ve mortalite sonuçları değerlendirilmiştir. Bulgular: CRP düzeyleri 5-100 mg/L arasında olan hastalar daha sık enfektif olmayan nedenlerle tanı alırken, CRP düzeyleri 101 mg/L ve üzerinde olan hastaların çoğunlukla enfektif nedenlerle tanı aldığı gözlemlenmiştir. Yükselmiş CRP düzeyleri ile artmış hastaneye yatış ve mortalite oranları arasında istatistiksel olarak anlamlı bir ilişki bulunmuştur (p < 0,001). Sonuç: Travmatik olmayan sebeplerle acil servise başvuran geriatrik hastalarda CRP düzeyleri ile konsültasyon ve hastaneye yatış oranları arasında anlamlı bir ilişki gözlemlenmiştir. Ayrıca, yüksek CRP düzeylerinin hastaneye yatırılan hastalar arasında artan mortalite oranları ile güçlü bir şekilde ilişkili olduğu tespit edilmiştir. Bulgular, CRP düzeylerinin 101 mg/L'yi aşması durumunda enfektif tanılar ve olumsuz sonuçlarla ilişkili olduğunu göstermekte ve bu hastaların yakından izlenmesi gerektiğini vurgulamaktadır. CRP düzeyleri, geriatrik hastaların acil servislerdeki karar verme süreçlerinde önemli bir faktör olarak değerlendirilmelidir.
