Determination of Probability Distributions and Statistical Analysis of the Number of Patients Visiting the Emergency Department of Sivas Cumhuriyet University Hospital

Sivas Cumhuriyet Üniversitesi Hastanesi Acil Servisine Gelen Hasta Sayılarına Uygun İhtimal Dağılımlarının Belirlenmesi Ve İstatistiksel Analizi

Abstract

In this study, it is aimed to determine the probability distribution that best fits a data group and to show the use of statistical techniques, as well as to collect and process data based on the number of patients who come to the emergency department, to evaluate the results by statistical analysis of these data, and to contribute to the literature in this way. . Cumhuriyet University Emergency Service was chosen as the application area and an application was made using the data of the patients.

The records kept by the Chief Physician of Cumhuriyet University Health Services Application and Research Hospital between 00:00 and 04:00 hours in a year between November 2017 and November 2018 were compiled and 4978 data used in the study were obtained in this way. From the data obtained, the data on the number of patients who applied to the emergency department and the frequency of the time between two consecutive patients were examined, and the discrete and continuous distributions of these variables were examined with the help of Kolmogorov-Smirnov, Anderson-Darling and Chi-square goodness-of-fit tests.

When the time elapsed between the two patients was analyzed by dividing the days and weeks of the months, it was determined that all of the data in question were compatible with all of the Exponential, Weibull, Gamma, Lognormal, Uniform and Normal distributions. When the number of patients was analyzed according to the days of the months, it was determined that the number of patients who applied to the emergency department on Monday, Wednesday, Saturday and Sunday showed compliance with the Poisson distribution according to the Kolmogorov-Smirnov goodness-of-fit test.
