■每年7月,新居民开始在美国各地接受培训,但尚不清楚这是否会影响危重患者如糖尿病酮症酸中毒(DKA)的死亡率.
■这项全国回顾性队列研究包括2016年至2020年间接受DKA急性护理的18岁或以上患者。数据来自全国住院患者样本数据库。我们比较了7月和8月收治的患者与其余几个月收治的患者,并评估了全因住院死亡率的主要终点。我们还使用多变量逻辑回归分析获得了针对混杂因素进行调整的比值比。次要终点包括住院时间,医院总费用,机械通气的粗速率,需要血液透析的急性肾损伤,和血管加压药的要求。假设检验采用分类变量的卡方检验和连续变量的学生t检验。双尾P值<0.05被认为具有统计学意义。
■在5年内确定的269,095例住院诊断为DKA,250,990符合纳入标准。7月和8月,发生42,668(17%)住院,和208,322(83%)发生在其余几个月。病人的平均年龄是47岁,并且队列之间没有显着差异(P=0.41)。女性患者占总患者的54%,并且队列之间没有差异(P=0.68)。在入院的病人中,61%是白人,21%是黑人,11%是西班牙裔,队列之间没有差异(P=0.38)。医疗保险(35%)和医疗补助(30%)是大多数患者的主要支付者,大约25%的人有私人保险。在主要支付者方面,队列之间没有差异(P=0.49)。平均逗留时间为7天,总住院费用为85,509美元。7月或8月入院并没有增加住院患者死亡率的几率(调整后的比值比0.96,P=0.58)。
■在这项DKA患者的回顾性队列研究中,7月和8月期间的住院护理并未增加住院死亡率.
UNASSIGNED: Every July, new residents begin training across the United States, but it is unclear whether this affects the mortality rate of critically ill patients such as those with diabetes ketoacidosis (DKA).
UNASSIGNED: This national retrospective cohort study included patients aged 18 years or older admitted to acute care with DKA between 2016 and 2020. Data were obtained from the National Inpatient Sample Database. We compared patients admitted in July and August with those admitted during the remaining months and assessed the primary endpoint of all-cause inpatient mortality. We also obtained an odds ratio adjusted for confounders using multivariate logistic regression analysis. Secondary endpoints included length of hospital stay, total hospital charges, the crude rate of mechanical ventilation, acute kidney injury requiring hemodialysis, and vasopressor requirement. Hypothesis testing was conducted using the chi-square test for categorical variables and Student\'s t test for continuous variables. A two-tailed P value of < 0.05 was considered statistically significant.
UNASSIGNED: Of the 269,095 hospitalizations identified over 5 years with a discharge diagnosis of DKA, 250,990 met the inclusion criteria. During July and August, 42,668 (17%) hospitalizations occurred, and 208,322 (83%) occurred during the remaining months. The mean age of the patients was 47 years, and there was no significant difference among the cohorts (P = 0.41). Female patients represented 54% of the total patients, and there was no difference between the cohorts (P = 0.68). Of the admitted patients, 61% were White, 21% were Black, and 11% were Hispanic, with no differences between the cohorts (P = 0.38). Medicare (35%) and Medicaid (30%) were the primary payers for most patients, and approximately 25% had private insurance. There were no differences between the cohorts in terms of primary payers (P = 0.49). The mean length of stay was 7 days, and the total hospitalization cost was $85,509. Admission in July or August did not increase the odds of inpatient mortality (adjusted odds ratio 0.96, P = 0.58).
UNASSIGNED: In this retrospective cohort study of patients admitted with DKA, inpatient care during July and August did not increase the odds of inpatient mortality.
