We examined the factors related to a reduction in the use of low-intensity pulsed ultrasound (LIPUS) for patients at both our hospital and other affiliated institutions.
Of 350 patients who used LIPUS at our and other affiliated institutions from May 2010 to April 2015, 279 (168 males, 111 females) were evaluated, after excluding mortalities and those with unexplained bone adhesion. Those patients with LIPUS compliance [calculated as: (number of days LIPUS was used/number of days LIPUS was available) × 100] below 80% were defined as the non-compliant group (170 patients), and those patients with a compliance rate of 80% or above were defined as the compliant group (109 patients). Factors related to a reduction in compliance were examined and included duration of use, age, sex, fracture side (right or left), and fracture site.
The duration of use was longer in the non-compliant group compared with that in the compliant group (mean ± SD: 160 ± 118 days vs. 126 ± 81 days; P = 0.01), and the mean age was younger in the non-compliant group (42 ± 20 years vs. 50 ± 21 years; P = 0.002). Additionally, there was a higher ratio of females/males in the compliant group (60/49 vs. 120/50; P = 0.008). However, the side of the fracture was not significantly different between the groups (P = 0.449). Fractures of the forearm were more frequent in the non-compliant group than that in the compliant group (25/170 vs. 7/109; P = 0.003).
The results suggest that the factors predictive of a reduction in the use of LIPUS are a long period of use, younger age, male gender, and use on fractures of the forearm.
我们研究了我院及其他附属机构中与低强度脉冲超声（LIPUS）使用减少相关的因素。
在2010年5月至2015年4月期间于我院及其他附属机构使用LIPUS的350例患者中，排除死亡病例及骨粘连原因不明者后，对279例（男性168例，女性111例）进行评估。将LIPUS依从性[计算方法为：（LIPUS使用天数/LIPUS可用天数）×100]低于80%的患者定义为非依从组（170例患者），将依从率80%及以上的患者定义为依从组（109例患者）。研究了与依从性降低相关的因素，包括使用时长、年龄、性别、骨折部位（右侧或左侧）以及骨折位置。
非依从组的使用时长比依从组长（均值±标准差：160±118天 vs. 126±81天；P = 0.01），非依从组的平均年龄更年轻（42±20岁 vs. 50±21岁；P = 0.002）。此外，依从组中女性/男性的比例更高（60/49 vs. 120/50；P = 0.008）。然而，两组之间骨折部位无显著差异（P = 0.449）。非依从组中前臂骨折比依从组更常见（25/170 vs. 7/109；P = 0.003）。
结果表明，LIPUS使用减少的预测因素为使用时间长、年龄小、男性以及用于前臂骨折。
