Predictive Performance of Mortality in Postoperative Patients with Gastric Ulcer at Somdet Phra Yupparat Kuchinarai Hospital, 2020-2024

Abstract

     This study was survey research by retrospective aimed to assess the predictive effectiveness of mortality among postoperative gastric ulcer patients at Kuchinarai Crown Prince Hospital, Kalasin Province, during the years 2020–2024. The study included a sample of 480 patients who underwent surgery for gastric ulcers at Kuchinarai Crown Prince Hospital between 2020 and 2024. Data were collected using structured questionnaires and analyzed using descriptive statistics, including frequency, percentage, mean, standard deviation, minimum, and maximum values. Inferential statistical methods such as the Chi-square test and odds ratio (OR) with a 95% confidence interval (95% CI) were used to determine relationships, with a significance level set at 0.05.
     Results: Factors significantly associated with mortality in postoperative gastric ulcer patients at Kuchinarai Crown Prince Hospital, at a statistical significance level of 0.05, include: Diabetic patients were found to have over 30 times the odds of mortality compared to non-diabetic individuals (OR = 30.74, 95% CI = 12.86–73.52, p-value < 0.001). Patients with liver disease exhibited over 35 times higher odds of mortality (OR = 35.769, 95% CI = 20.929–61.132, p-value < 0.001), while those with cancer had over 38 times greater odds (OR = 38.667, 95% CI = 22.121–67.586, p-value < 0.001). Additionally, urinary tract infections were associated with a 23-fold increase in mortality risk compared to uninfected patients (OR = 23.600, 95% CI = 15.369–36.239, p-value < 0.001).
