The correlation of risk factors with mortality of geriatric patients in non-operating room anesthesia services

Background & objective: One of the most frequently performed anesthesia services is Non-Operating Room Anesthesia (NORA). In geriatric patients, there are several risk factors which are directly or indirectly related to post-NORA mortality. We aimed to find out the relationship between pre-NORA risk factors and the mortality of geriatric patients receiving NORA services. Methods: This observational analytical study used the convenient sampling method in seventy patients undergoing NORA. Data collected included pre-NORA risk factors; e.g., age, gender, Body Mass Index (BMI), quality of life, and cognitive function. Mortality within 30 days post-NORA was noted. The data was analyzed using an independent t-test and Spearman correlation with α= 5% and a confidence interval (CI) of 95%. Results: We included 70 patients as the subject of the study, with a mortality rate of 8.6%. There was a significant difference between BMI (P = 0.034), quality of life (P = 0.001), and cognitive function (P = 0.004) in patients who died with those who remained alive. There were correlations between cognitive function (P = 0.001, R= 0.379) and quality of life (P = 0.009, R= 0.309) with 30 days post-NORA mortality. Conclusion: There is a positive correlation between the risk factors of cognitive function and quality of life pre-NORA of geriatric patients with 30-day mortality post-NORA. Careful selection and maximum optimization of the geriatric patients selected for non-operating room anesthesia may reduce post-operative mortality.
