To compare use of the conventional intravitreal injection method to the InVitria intravitreal injection device. Three outcome measures were studied: patient comfort, speed of injection and cost-effectiveness.
A prospective review of 58 patients was undertaken. Patients scored their perceived pain for each part of the conventional injection method using visual analogue scales (VAS), which allows pain to be scored from 0 (no pain) to 100. The same 58 patients scored their perceived pain for each part of the injection process with the InVitria on their follow-up visit. The procedure was timed in both settings and cost to the Trust was analysed.
Pain scores when the InVitria was used were lower than when the conventional method was used for all aspects of the intravitreal injection procedure, in particular, when comparing insertion of drape/speculum (mean score 57.56) to insertion the InVitria (mean score 16.50), needle entry (mean score 37.76 to 27.86) and removal of the drape/speculum (mean score 38.72) to removal of the InVitria (11.07). The reduction in pain scores was statistically significant for all aspects of the procedure, except the initial instillation of drops. The InVitria was an average of 1 minute and 32 seconds faster than the conventional method. Use of the InVitria in place of the conventional method provides an annual saving of £24,300 to the Trust based on the number of injections currently performed.
The introduction of the InVitria in the Newcastle Eye Centre has had a positive impact on patient comfort, time and cost to the Trust.
比较传统玻璃体内注射方法与InVitria玻璃体内注射装置的使用情况。研究了三项结果指标：患者舒适度、注射速度和成本效益。
对58例患者进行了前瞻性评估。患者使用视觉模拟量表（VAS）对传统注射方法各部分的疼痛感受进行评分，VAS可将疼痛从0分（无疼痛）至100分进行评分。这58例患者在随访时使用InVitria对注射过程各部分的疼痛感受进行评分。对两种情况下的操作进行计时，并分析信托机构的成本。
在玻璃体内注射过程的所有方面，使用InVitria时的疼痛评分均低于使用传统方法时，特别是在比较铺巾/开睑器插入（平均评分57.56）与InVitria插入（平均评分16.50）、进针（平均评分37.76对27.86）以及铺巾/开睑器移除（平均评分38.72）与InVitria移除（11.07）时。除最初滴眼药水外，该操作所有方面的疼痛评分降低均具有统计学意义。InVitria比传统方法平均快1分32秒。根据目前的注射次数，使用InVitria代替传统方法可为信托机构每年节省24,300英镑。
在纽卡斯尔眼科中心引入InVitria对患者舒适度、时间以及信托机构的成本产生了积极影响。
