Background: Evaluation of biomarkers as risk factors for mortality may provide early intervention and treatment for fatal diseases. We aimed to determine the usability of inexpensive and easily measurable tests in the differentiation of critically ill patients by investigating their relationship with mortality.
Methods: This study was executed by examining the sixth, third, and first month examinations of patients registered to the home health care services unit in 2022 before mortality due to any reason. This study was conducted by including 1,060 patients. All parameters were distributed non-parametrically. The difference between the dependent groups was evaluated with Friedman’s two-way analysis of variance, and p < 0.05 was considered statistically significant.
Results: When the patients’ premortem one-month, three-month, and six-month results were examined, there was an increase in mean platelet volume (MPV) values over time. The neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR) also increased. In these two parameters, the difference between the first and third months and between the first and sixth months was statistically significant. Given the C-Reactive Protein (CRP)/Albumin Ratio (CAR) and CRP/Prealbumin results, a significant increase was observed in both ratios. A more than four-fold increase was observed in the CAR between the premortem first and sixth month results, which increased gradually over time and was statistically significant.
Conclusıons: NLR, PLR, MPV, CAR and CRP/Prealbumin values were statistically associated with mortality.
