In cross-sectional studies, patient activation has been associated with better health behaviors, health outcomes, and health-care experiences. Moreover, tailored interventions have led to clinically meaningful improvements in patient activation, as well as health outcomes over time. We tested whether a tailored patient-activation letter communicating bone mineral density (BMD) test results plus an educational brochure improved patient activation scores and levels at 12 and 52 wk post-baseline as the mechanism leading to enhanced bone healthcare. In a randomized, controlled, double-blinded, multicenter pragmatic clinical trial, we randomized 7749 patients ≥50 yr old and presenting for BMD testing at 3 medical centers in the United States between February 2012 and August 2014. The outcome measures were patient activation scores and levels based on 6 items taken from the Patient Activation Measure (PAM) that were administered at the baseline, 12-wk, and 52-wk follow-up interviews. Mean age was 66.6 yr, 83.8% were women, and 75.3% were Non-Hispanic-Whites. Overall, PAM activation scores improved from 58.1 at baseline to 76.4 by 12 wk (p < 0.001) and to 77.2 (p = 0.002) by 52 wk post-baseline. These improvements, however, were not significantly different between the intervention and usual care groups (18.7 vs 18.1, p = 0.176, at 12 wk) in intention-to-treat analyses. PAM activation scores and levels substantially improved at 12 wk and 52 wk, but no differences were observed in these improvements between the intervention and usual care groups. These null findings may have occurred because the tailoring focused on the patient's BMD and fracture risk results, rather than on the patient's BMD and fracture risk results as well as the patient's baseline PAM activation scores or levels.
在横断面研究中,患者的激活状态与更好的健康行为、健康结果及医疗保健体验相关。此外,量身定制的干预措施已使患者的激活状态以及长期的健康结果在临床上得到了有意义的改善。我们测试了一封传达骨密度(BMD)检测结果的量身定制的患者激活信以及一本教育手册,是否能在基线后12周和52周提高患者的激活分数和水平,以此作为改善骨骼医疗保健的机制。在一项随机、对照、双盲、多中心实用型临床试验中,我们将2012年2月至2014年8月期间在美国3个医疗中心进行BMD检测的7749名50岁及以上患者随机分组。结局指标是基于从患者激活量表(PAM)中选取的6个项目得出的患者激活分数和水平,这些项目在基线、12周和52周随访访谈时进行测量。平均年龄为66.6岁,83.8%为女性,75.3%为非西班牙裔白人。总体而言,PAM激活分数从基线时的58.1提高到12周时的76.4(p<0.001),基线后52周时提高到77.2(p = 0.002)。然而,在意向性分析中,干预组和常规护理组之间在这些改善方面没有显著差异(12周时为18.7对18.1,p = 0.176)。PAM激活分数和水平在12周和52周时大幅提高,但干预组和常规护理组在这些改善方面未观察到差异。这些无效结果可能是因为量身定制侧重于患者的BMD和骨折风险结果,而不是患者的BMD和骨折风险结果以及患者的基线PAM激活分数或水平。
