Introduction: Delirium is an acute and predominantly reversible condition that may arise from various factors, including underlying illness, pharmacological interventions, toxic exposure, and significant stress. It represents the most prevalent challenge encountered in intensive care units. The purpose of this study is to examine the incidence and risk factors associated with postoperative delirium following hip fracture surgeries conducted within the intensive care setting.
Methods: The institutional ethics committee approved this prospective observational study. Upon admission, the attending physician provided patients or their family members with information regarding their participation in the survey, while the principal investigator secured consent from all individuals involved. A total of sixty-five patients aged 18 years and older were admitted to the Intensive Care Unit (ICU) at SRM Hospital and Research Institute. The study cohort included individuals presenting with trauma, surgical, and medical conditions. The principal investigator systematically collected relevant data by reviewing the patient's medical records. Each patient underwent daily evaluation for delirium by a trained physician utilizing the standardized diagnostic tool, the Confusion Assessment Method for the ICU (CAM-ICU). The data collection process was carried out with careful attention to detail and accuracy.
Results: In a study involving 65 patients, the incidence of delirium among individuals in the intensive care unit (ICU) was found to be 18.4%. The analysis indicated that the risk of developing delirium is significantly associated with both the duration of surgical procedures and the length of hospital stay, with a p-value of less than 0.005 confirming these findings through statistical evaluation.
Conclusion: In our investigation, we identified that the incidence of delirium following hip fracture surgeries is 18.4%. We found a direct correlation between the duration of the surgical procedure and the length of hospital stay with the occurrence of delirium. However, our analysis did not reveal any significant associations with variables such as age, gender, type of anesthesia, total white blood cell count, platelet count, renal function tests, acid-base imbalances, liver function tests, creatinine levels, electrolyte levels, including sodium, potassium, magnesium, and calcium.
