The lack of a reliable approach to assess quality of pain care hinders quality improvement initiatives. Rule-based natural language processing algorithms were used to extract pain care quality (PCQ) indicators from documents of Veterans Health Administration primary care providers for veterans diagnosed within the past year with musculoskeletal disorders with moderate-to-severe pain intensity across 2 time periods 2013 to 2014 (fiscal year [FY] 2013) and 2017 to 2018 (FY 2017). Patterns of documentation of PCQ indicators for 64,444 veterans and 124,408 unique visits (FY 2013) and 63,427 veterans and 146,507 visits (FY 2017) are described. The most commonly documented PCQ indicators in each cohort were presence of pain, etiology or source, and site of pain (greater than 90% of progress notes), while least commonly documented were sensation, what makes pain better or worse, and pain's impact on function (documented in fewer than 50%). A PCQ indicator score (maximum = 12) was calculated for each visit in FY 2013 (mean = 7.8, SD = 1.9) and FY 2017 (mean = 8.3, SD = 2.3) by adding one point for every indicator documented. Standardized Cronbach alpha for total PCQ scores was 0.74 in the most recent data (FY 2017). The mean PCQ indicator scores across patient characteristics and types of healthcare facilities were highly stable. Estimates of the frequency of documentation of PCQ indicators have face validity and encourage further evaluation of the reliability, validity, and utility of the measure. A reliable measure of PCQ fills an important scientific knowledge and practice gap.

缺乏评估疼痛护理质量的可靠方法阻碍了质量改进举措。使用基于规则的自然语言处理算法从退伍军人健康管理局初级保健提供者的文件中提取疼痛护理质量 (PCQ) 指标，这些指标针对过去一年内诊断出患有肌肉骨骼疾病、2013 年 2 个时间段的中度至重度疼痛的退伍军人至 2014 年（2013 财年）和 2017 至 2018 年（2017 财年）。描述了 64,444 名退伍军人和 124,408 次独特访问（2013 财年）以及 63,427 名退伍军人和 146,507 次访问（2017 财年）的 PCQ 指标的记录模式。每个队列中最常记录的 PCQ 指标是疼痛的存在、病因或来源以及疼痛部位（超过 90% 的进展记录），而最不常见的记录是感觉、使疼痛好转或恶化的原因以及疼痛对身体的影响。函数（记录在案的数量少于 50%）。通过为记录的每个指标加一分，计算 2013 财年（平均值 = 7.8，SD = 1.9）和 2017 财年（平均值 = 8.3，SD = 2.3）每次访问的 PCQ 指标得分（最大值 = 12）。最新数据（2017 财年）中 PCQ 总分的标准化 Cronbach alpha 为 0.74。不同患者特征和医疗机构类型的平均 PCQ 指标得分高度稳定。对 PCQ 指标记录频率的估计具有表面有效性，并鼓励进一步评估该措施的可靠性、有效性和实用性。PCQ 的可靠测量填补了重要的科学知识和实践空白。
