Following an international push for financing reforms, many low- and middle-income countries introduced user fees to raise additional revenue for health systems. User fees are charges levied at the point of use and are supposed to help reduce 'frivolous' consumption of health services, increase quality of services available and, as a result, increase utilisation of services.
To assess the effectiveness of introducing, removing or changing user fees to improve access to care in low-and middle-income countries
We searched 25 international databases, including the Cochrane Effective Practice and Organisation of Care (EPOC) Group's Trials Register, CENTRAL, MEDLINE and EMBASE. We also searched the websites and online resources of international agencies, organisations and universities to find relevant grey literature. We conducted the original searches between November 2005 and April 2006 and the updated search in CENTRAL (DVD-ROM 2011, Issue 1); MEDLINE In-Process & Other Non-Indexed Citations, Ovid (January 25, 2011); MEDLINE, Ovid (1948 to January Week 2 2011); EMBASE, Ovid (1980 to 2011 Week 03) and EconLit, CSA Illumina (1969 - present) on the 26th of January 2011.
We included randomised controlled trials, interrupted time-series studies and controlled before-and-after studies that reported an objective measure of at least one of the following outcomes: healthcare utilisation, health expenditures, or health outcomes.
We re-analysed studies with longitudinal data. We computed price elasticities of demand for health services in controlled before-and-after studies as a standardised measure. Due to the diversity of contexts and outcome measures, we did not perform meta-analysis. Instead, we undertook a narrative summary of evidence.
We included 16 studies out of the 243 identified. Most of the included studies showed methodological weaknesses that hamper the strength and reliability of their findings. When fees were introduced or increased, we found the use of health services decreased significantly in most studies. Two studies found increases in health service use when quality improvements were introduced at the same time as user fees. However, these studies have a high risk of bias. We found no evidence of effects on health outcomes or health expenditure.
AUTHORS' CONCLUSIONS: The review suggests that reducing or removing user fees increases the utilisation of certain healthcare services. However, emerging evidence suggests that such a change may have unintended consequences on utilisation of preventive services and service quality. The review also found that introducing or increasing fees can have a negative impact on health services utilisation, although some evidence suggests that when implemented with quality improvements these interventions could be beneficial. Most of the included studies suffered from important methodological weaknesses. More rigorous research is needed to inform debates on the desirability and effects of user fees.
在国际社会推动融资改革之后,许多低收入和中等收入国家开始收取使用者费,以增加卫生系统的额外收入。使用者费是在使用时收取的费用,旨在帮助减少对卫生服务的“随意”消费,提高可得服务的质量,进而提高服务利用率。
评估引入、取消或改变使用者费对改善低收入和中等收入国家医疗服务可及性的效果。
我们检索了25个国际数据库,包括考克兰有效实践与护理组织(EPOC)小组的试验注册库、Cochrane系统评价数据库、医学索引数据库和荷兰医学文摘数据库。我们还检索了国际机构、组织和大学的网站及在线资源,以查找相关的灰色文献。我们在2005年11月至2006年4月期间进行了最初的检索,并于2011年1月26日在Cochrane系统评价数据库(DVD-ROM 2011年第1期)、Ovid平台的医学索引数据库在研及其他非索引引文(2011年1月25日)、Ovid平台的医学索引数据库(1948年至2011年第2周)、Ovid平台的荷兰医学文摘数据库(1980年至2011年第3周)以及CSA Illumina平台的经济文献数据库(1969年至今)进行了更新检索。
我们纳入了随机对照试验、中断时间序列研究以及前后对照研究,这些研究报告了至少以下一项结果的客观测量指标:医疗服务利用率、卫生支出或健康结局。
我们对具有纵向数据的研究进行了重新分析。在前后对照研究中,我们计算了卫生服务需求的价格弹性作为标准化测量指标。由于背景和结局测量指标的多样性,我们未进行Meta分析。相反,我们对证据进行了叙述性总结。
在识别出的243项研究中,我们纳入了16项。大多数纳入研究显示出方法学上的弱点,这妨碍了其研究结果的强度和可靠性。当引入或提高费用时,我们发现大多数研究中卫生服务的使用显著减少。两项研究发现,在引入使用者费的同时进行质量改进时,卫生服务的使用有所增加。然而,这些研究存在较高的偏倚风险。我们没有发现对健康结局或卫生支出有影响的证据。
该综述表明,降低或取消使用者费会增加某些医疗服务的利用率。然而,新出现的证据表明,这种变化可能对预防服务的利用率和服务质量产生意想不到的后果。该综述还发现,引入或提高费用可能对卫生服务利用率产生负面影响,尽管一些证据表明,当与质量改进措施一起实施时,这些干预措施可能是有益的。大多数纳入研究存在重要的方法学弱点。需要更严格的研究来为关于使用者费的可取性和效果的辩论提供信息。
