Abstract

Background: Vision impairment and blindness are significant global public health challenges, particularly in low- and middle-income countries, where access to eye care services remains limited. India has significantly reduced the prevalence of Blindness and Vision Impairment (VI) over the last two decades. This was achieved with the help of greater investments towards blindness control programs. The use of utility values helps in conducting economic evaluations of various eye health programs and empirically justify investing in these programs. This study aimed to estimate utility values for various childhood eye conditions in central India using the EuroQol-Five-Dimension-Youth (EQ-5D-Y) instrument.

Methods: This is a before and after study with data collected at two time points for few participants and at only one time point for others. This study was undertaken at Shri Sadguru Netra Chikitsalaya (SNC) and included children representing central and north India. Participants were randomly sampled in the hospital. After comprehensive eye examination, participants completed the EuroQol-Five-Dimension-Youth (EQ-5D-Y) questionnaire along with EuroQol Visual Analogue Scale (EQ VAS) measurement to elicit their health state for their condition which was repeated after six months post-intervention to measure the change in utility value. We have used Indonesian value set to analyze the preference scores of each dimension of EQ-5D-Y.

Results: Utility values of 16 eye conditions were estimated at baseline and seven conditions were followed up for post-intervention utility value estimation. There is a statistically significant improvement in the utility values post-intervention amongst six conditions. Blindness and Pediatric cataract had the greatest change (0.23 and 0.2 respectively) in utility value whereas mild Vision Impairment (VI) showed the least change (0.02) in the utility value post-intervention. Blindness had the lowest baseline (0.62) and post-intervention (0.85) utility value.

Conclusion: The utility values estimated in this study showed that generic measures such as EQ-5D-Y may be used to elicit health states for various eye conditions amongst children. These estimates are helpful in undertaking cost-utility analyses of eye health programs and interventions aimed at these eye conditions.

使用 EQ-5D-Y 工具测量印度儿童眼疾的效用值。
背景:视力损伤和失明是全球公共卫生面临的重大挑战,尤其是在中低收入国家,这些国家的眼科保健服务仍然有限。在过去的二十年里,印度大幅降低了盲症和视力损伤(VI)的发病率。这得益于对防盲项目的更多投资。使用效用值有助于对各种眼健康项目进行经济评估,并从经验上证明投资这些项目的合理性。本研究旨在使用欧洲五维儿童质量标准(EQ-5D-Y)估算印度中部地区各种儿童眼病的效用值:这是一项前后对比研究,少数参与者在两个时间点收集数据,其他参与者只在一个时间点收集数据。这项研究在 Shri Sadguru Netra Chikitsalaya(SNC)进行,包括印度中部和北部的儿童。参与者在医院内随机抽样。在进行了全面的眼部检查后,参与者填写了 EuroQol-Five-Dimension-Youth (EQ-5D-Y) 问卷和 EuroQol Visual Analogue Scale (EQ VAS) 测量表,以了解他们的健康状况,并在干预后六个月重复测量,以衡量效用值的变化。我们使用印尼价值集来分析 EQ-5D-Y 各维度的偏好得分:结果:对 16 种眼部状况的效用值进行了基线估算,并对 7 种状况进行了干预后效用值估算。干预后,有六种情况的效用值在统计学上有明显改善。失明和小儿白内障的效用值变化最大(分别为 0.23 和 0.2),而轻度视力障碍(VI)在干预后的效用值变化最小(0.02)。失明的效用值基线最低(0.62),干预后最低(0.85):本研究估算的效用值表明,EQ-5D-Y 等通用测量方法可用于了解儿童各种眼部疾病的健康状况。这些估计值有助于对针对这些眼疾的眼健康计划和干预措施进行成本效用分析。
