Introduction The purpose of this study was to estimate the positive predictive value (PPV) of International Classification of Diseases, 10th Revision, Clinical Modification (ICD-10-CM) codes for injury, poisoning, physical or sexual assault complicating pregnancy, childbirth and the puerperium (PCP) to capture injury encounters within both hospital and emergency department claims data. Methods A medical record review was conducted on a sample (n=157) of inpatient and emergency department claims from one Kentucky healthcare system from 2015 to 2017, with any diagnosis in the ICD-10-CM range O9A.2-O9A.4. Study clinicians reviewed medical records for the sampled cases and used an abstraction form to collect information on documented presence of injury and PCP complications. The study estimated the PPVs and the 95% CIs of O9A.2-O9A.4 codes for (1) capturing injuries and (2) capturing injuries complicating PCP. Results The estimated PPV for the codes O9A.2-O9A.4 to identify injury in the full sample was 79.6% (95% CI 73.3% to 85.9%) and the PPV for capturing injuries complicating PCP was 72.0% (95% CI 65.0% to 79.0%). The estimated PPV for an inpatient principal diagnosis O9A.2-O9A.4 to capture injuries was 90.7% (95% CI 82.0% to 99.4%) and the PPV for capturing injuries complicating PCP was 88.4% (95% CI 78.4% to 98.4%). The estimated PPV for any mention of O9A.2-O9A.4 in emergency department data to capture injuries was 95.2% (95% CI 90.6% to 99.9%) and the PPV for capturing injuries complicating PCP was 81.0% (95% CI 72.4% to 89.5%). Discussion The O9A.2-O9A.4 codes captured high percentage true injury cases among pregnant and puerperal women.

验证 ICD-10-CM 代码对妊娠、分娩和产褥期的并发症：医疗记录审查

简介 本研究的目的是估计国际疾病分类第 10 次修订、临床修改 (ICD-10-CM) 代码对妊娠、分娩和妊娠并发症的伤害、中毒、身体或性侵犯的阳性预测值 (PPV)。产褥期 (PCP) 以捕获医院和急诊科索赔数据中的伤害遭遇。方法 对 2015 年至 2017 年来自肯塔基州一个医疗保健系统的住院和急诊科索赔样本 (n=157) 进行了病历审查，其中任何诊断都在 ICD-10-CM 范围 O9A.2-O9A.4 内。研究临床医生审查了抽样病例的医疗记录，并使用抽象表格收集有关受伤和 PCP 并发症的记录信息。该研究估计了 O9A.2-O9A 的 PPV 和 95% CI。4 个代码用于 (1) 捕获伤害和 (2) 捕获使 PCP 复杂化的伤害。结果 用于识别全样本损伤的代码 O9A.2-O9A.4 的估计 PPV 为 79.6%（95% CI 73.3% 至 85.9%），捕获 PCP 并发症的 PPV 为 72.0%（95% CI 65.0） % 至 79.0%）。住院主要诊断 O9A.2-O9A.4 捕获损伤的估计 PPV 为 90.7%（95% CI 82.0% 至 99.4%），捕获并发 PCP 损伤的 PPV 为 88.4%（95% CI 78.4% 至 98.4） %）。在急诊科数据中任何提及 O9A.2-O9A.4 以捕获伤害的估计 PPV 为 95.2%（95% CI 90.6% 至 99.9%），捕获使 PCP 复杂化的伤害的 PPV 为 81.0%（95% CI 72.4 % 到 89.5%）。讨论 O9A.2-O9A.4 代码在孕妇和产褥期妇女中捕获了高百分比的真实伤害案例。
