一种新方法有效地使用行政索赔数据识别新生儿重症监护室 (NICU) 的入院情况. 这个定义,使用国际疾病分类,第10版,临床修改 (ICD-10-CM) 和当前程序术语 (CPT) 代码,是可适应和可重复的.
科学领域:
- 医疗信息学 医疗信息学
- 儿科 儿科 儿科
- 医疗保健服务研究 医疗服务研究
背景情况:
- 准确识别新生儿重症监护室 (NICU) 的入院情况对于医疗保健分析至关重要.
- 行政索赔数据为流行病学研究提供了宝贵的资源,但需要对特定患者队列进行精确的定义.
研究的目的:
- 开发和验证一种可靠的方法,使用行政索赔数据识别NICU入院情况.
- 建立适用于不同数据集的NICU入院的灵活和可重复的定义.
主要方法:
- 追溯队列研究,利用2016-2020年间的非识别索赔数据.
- 根据国际疾病分类,第10版,临床修改 (ICD-10-CM),当前程序术语 (CPT) 和收入代码,制定NICU入院的定义.
- 统计分析包括卡帕统计,积极预测值 (PPV) 和95%置信区间 (CI) 来评估代码一致性和准确性.
主要成果:
- 结合CPT和收入代码的使用,发现NICU住院比例最高 (13.7%),与早产率保持一致.
- 仅收入代码就发现了更多的NICU住院 (3.3%),而不是单独的CPT代码 (1.5%).
- 当CPT代码是标准时,收入代码的准确性很高,识别了86%的NICU入院 (敏感性) 和97%的非NICU入院 (特异性).
结论:
- 通过使用行政数据,成功开发出了用于识别新生儿入院的强有力的定义.
- 已建立的NICU代码定义具有高度适应性,可重复性和灵活性,可用于各种数据集.
- 这种方法提高了行政索赔数据的实用性,用于研究新生儿护理和结果.
