In several OECD countries the percentage of people over 80 in LTC institutions has been declining for more than a decade, despite population ageing. The standard model to explain healthcare utilization, the Andersen model, cannot explain this trend. We extend the Andersen model by including proxies for the relative attractiveness of community living compared to institutional care. Using longitudinal data on long-term care use in the Netherlands from 1996 to 2012, we examine to what extent a decline in institutional care is associated with changes in perceived attractiveness of institutional LTC care compared to community living.
With a Blinder-Oaxaca decomposition regression, we decomposed the difference in admission to LTC institutions between the period 1996-1999 and 2009-2012 into a part that accounts for differences in predictors of the Andersen model and an "unexplained" part, and investigate whether the perceived attractiveness of institutional care reduces the size of the unexplained part.
We find that factors related to the perceived attractiveness of institutional care compared to community living explains 12.8% of the unexplained negative time trend in admission rates over the total period (1996-2012), and 19.1-19.2% over shorter time frames.
Our results show that changes in the perceived attractiveness of institutional LTC may explain part of the decline in demand for institutional care. Our findings imply that policies to encourage community living may have a self-reinforcing effect.
在多个经合组织国家,尽管人口老龄化,但超过 80 岁的人在长期护理机构的比例已经下降了十多年。解释医疗保健利用的标准模型,即安德森模型,无法解释这一趋势。我们通过纳入社区生活相对于机构护理的相对吸引力的代理变量来扩展安德森模型。利用 1996 年至 2012 年荷兰长期护理使用的纵向数据,我们研究了机构护理的下降在多大程度上与机构长期护理护理相对于社区生活的感知吸引力的变化相关。
我们使用 Blinder-Oaxaca 分解回归,将 1996-1999 年和 2009-2012 年期间进入长期护理机构的差异分解为一个部分,该部分解释了安德森模型预测因素的差异,以及一个“无法解释”的部分,并研究了机构护理的感知吸引力是否会减小无法解释部分的大小。
我们发现,与社区生活相比,机构护理的感知吸引力相关的因素解释了总期间(1996-2012 年)入院率负向时间趋势中无法解释的部分的 12.8%,以及较短时间框架内的 19.1-19.2%。
我们的结果表明,机构长期护理感知吸引力的变化可能解释了机构护理需求下降的部分原因。我们的研究结果表明,鼓励社区生活的政策可能具有自我强化效应。
