为了确定医生在老年人的访问中文档活动能力受限的频率，以及与文档生成活动能力受限相关的患者、医生和实践特征，我们完成了2012-2016年国家就诊医疗护理调查的横断面分析。进行多元分析以确定与活动能力受限文档相关的患者、医生和实践水平因素。就诊医疗护理。我们分析65岁及以上的成年人的就诊。最终样本量代表了13亿赋权访问量。主要结果测量：我们通过诊断标准代码(ICD-9或ICD-10)是否记录了任何与活动能力受限相关的信息，定义有无活动能力受限。活动能力受限文档的总体患病率为2.4%。最常见的诊断代码是与跌倒有关的。与活动能力受限文档相关的患者级别因素包括85岁以上的个体(相对于65-69岁的个体[OR 2.32，95% CI 1.76-3.07])、关节炎的并存诊断(OR 1.35，1.18-2.01)和脑血管疾病的并存诊断(OR 1.60，1.13-2.26)。与活动能力受限文档不相关的患者级别因素包括男性就诊(OR 0.80，0.64-0.99)、癌症诊断的个体(OR 0.76，0.58-0.99)和为慢性问题寻求治疗的个体(相对于新问题[OR 0.36，0.29-0.44])。医生级别因素与活动能力受限文档的增加有关的包括神经学家的就诊(OR 4.48，2.41-8.32)和骨科医生的就诊(OR 2.67，1.49-4.79)，而与基层医疗医生相比。在实践水平上，活动能力文档的不同取决于来自医疗保险的实践收入的百分比。活动能力受限文档不足，可能主要在功能改变明显时捕捉到。版权所有©2023。Elsevier公司出版。

To determine how often physicians document mobility limitations in visits with older adults, and which patient, physician, and practice characteristics associate with documented mobility limitations.We completed a cross-sectional analysis of National Ambulatory Medical Care Surveys, years 2012-2016. Multivariate analyses were conducted to identify patient, physician, and practice-level factors associated with mobility limitation documentation.Ambulatory care visits.We analyzed visits with adults 65 years and older. Final sample size represented 1.3 billion weighted visits.N/A MAIN OUTCOME MEASURE: We defined the presence/absence of a mobility limitation by whether any ICD-9 or ICD-10 code related to mobility limitations were documented in the visits.The overall prevalence of mobility limitation documentation was 2.4%. The most common codes were falls-related. Patient-level factors more likely to be associated with mobility limitation documentation were visits by individuals over 85 years of age, relative to 65-69 years, (OR 2.32, 95% CI 1.76-3.07]; with a comorbid diagnosis of arthritis (OR 1.35, 1.18-2.01); and with a comorbid diagnosis of cerebrovascular disease (OR 1.60, 1.13-2.26). Patient-level factors less likely to be associated with mobility limitation documentation were visits by males (OR 0.80, 0.64-0.99); individuals with a cancer diagnosis (OR 0.76, 0.58-0.99); and by individuals seeking care for a chronic problem (relative to a new problem [OR 0.36, 0.29-0.44]). Physician-level factors associated with an increased likelihood of mobility limitation documentation were visits to neurologists (ORs 4.48, 2.41-8.32) and orthopedists (OR 2.67, 1.49-4.79) compared to primary care physicians. At the practice-level, mobility documentation varied based on the percentage of practice revenue from Medicare.Mobility limitations are under-documented and may be primarily captured when changes in function are overt.Copyright © 2023.
