After the confirmation of its safety, acceptability and feasibility in a cervical cancer prevention demonstration project in 2002, a visual inspection by acetic acid (VIA) followed by an effective treatment using cryotherapy as a single-visit approach (SVA) was recently introduced in five provinces having low Pap smear screening rates, in Thailand. The effectiveness of a screening program is usually associated with a high level of coverage; however, in low-resource settings such a high coverage is still hard to attain by the conventional Pap smear approach.
To evaluate whether VIA/SVA can increase women's access to the prevention services in low-resource provinces of Thailand.
A cross-sectional study was conducted by analysing electronic screening records of the provinces. A chi2 test was used in the comparisons of screening coverage between the year before and the first year of VIA/SVA implementation during 1998-2005.
This comparative study, which included 88 554 screening visits totally, shows a significant increase in the screening coverage of five provinces after the VIA/SVA implementation (P < 0.001). As a result of the large substitution of VIA/SVA for Pap smears, the costs of screening were lowered by as much as $US362,300 (66.8%) in the first year.
VIA/SVA has provided good screening coverage and lowered the financial burden in five low-resource provinces of Thailand. Therefore, it is promisingly competitive as a potential alternative means of cervical cancer prevention in low-resource areas.
在2002年宫颈癌预防示范项目中确认了其安全性、可接受性和可行性后,泰国最近在五个巴氏涂片筛查率较低的省份引入了醋酸肉眼观察法(VIA),随后采用冷冻疗法进行单次就诊有效治疗(SVA)。筛查项目的有效性通常与高覆盖率相关;然而,在资源匮乏地区,通过传统的巴氏涂片方法仍难以实现如此高的覆盖率。
评估VIA/SVA能否增加泰国资源匮乏省份妇女获得预防服务的机会。
通过分析各省的电子筛查记录进行横断面研究。在比较1998 - 2005年VIA/SVA实施前一年和第一年的筛查覆盖率时使用卡方检验。
这项总共包括88554次筛查就诊的比较研究表明,实施VIA/SVA后,五个省份的筛查覆盖率显著提高(P < 0.001)。由于VIA/SVA大量替代巴氏涂片,第一年的筛查成本降低了多达362300美元(66.8%)。
VIA/SVA在泰国五个资源匮乏省份提供了良好的筛查覆盖率,并减轻了经济负担。因此,作为资源匮乏地区宫颈癌预防的潜在替代方法,它具有很有前景的竞争力。
