The data on the following items were analyzed: the total hospital costs, the total costs covered by NHI and copayment by patients. Outcome measures Outcome measures were white blood cell (WBC) count at postoperative first day, time to soft diet, complication rate, surgical

site infection (SSI), length of hospital stay, and readmission within 30 days. Statistical analysis The data were analyzed using SAS enterprise ver. 5.1 statistical software (SAS Inc, Cary, NC, USA). Demographics and clinical characteristics were expressed as means for continuous Microtubule Associated inhibitor variables or proportions for categorical variables. The chi-square test was used to compare differences in categorical variables. Student’s t test or the Wilcoxon rank sum test was used to compare differences in continuous variables. The p value of less than 0.05 was considered statistically significant. Results selleck During the study period, a total of 478 patients underwent appendectomies, and 145 patients were excluded, leaving 333 who met inclusion criteria. Demographics and clinical characteristics of included cases are shown in Table 1. The mean age of patients was 35.4 years. There were 190 males (57.1%) and 143 females (42.9%). The average time from arrival at our hospital to diagnosis was 3.0 hours. The average 17-AAG nmr time from diagnosis as appendicitis to skin incision was 6.6 hours. The average

time form arrival to incision was 9.6 hours. Based on the time from arrival Ergoloid at our hospital to incision, they were divided into two groups: 177 (53.2%) in group A and 156 (46.8%) in group B. Table 1 Demographics and clinical characteristics Total number of cases 333 Age (years) 35.4 ± 12.4 Male: Female 190 (57.1%): 143 (42.9%) Body mass index (kg/m2) 23.0 ± 3.3 Initial body temperature (°C) 37.4 ± 0.7 Initial white blood cell (WBC) count (×103/mm3) 12.9 ± 3.9 Comorbidities 32 (9.6%) Hours from onset of symptoms to hospital 24.3 ± 29.9 Hours from arrival to diagnosis 3.0 ± 2.0 Hours from diagnosis to incision 6.6 ± 4.7 Hours from

There were significant differences in time parameter due to study design. There were no significant differences in age, sex ratio, body mass index (BMI), body temperature, initial WBC count, and comorbidities between two groups.
