This paper estimates the impact of spousal bereavement on hospital inpatient use for the surviving bereaved by following the experience of 94,272 married Scottish individuals from 1991 until 2009 using a difference-in-difference model. We also consider the sample selection issues related to differences in survival between the bereaved and non-bereaved using a simple Cox Proportional-Hazard model. Before conducting these estimations, propensity score approaches are used to re-weight the non-bereaved to generate a more random-like comparison sample for the bereaved. We find that those bereaved who survive are both more likely to be admitted and to stay longer in hospital than a comparable non-bereaved cohort. Bereavement is estimated to induce on average an extra 0.24 (95% CI [0.15, 0.33]) hospital inpatient days per year. Similar to previous studies, we estimate the bereaved have a 19.2% (95% CI [12.5%, 26.3%]) higher mortality rate than the comparable non-bereaved cohort.
本文通过使用差分模型，追踪了1991年至2009年间94272名已婚苏格兰人的经历，估计了配偶丧亲之痛对幸存丧亲者住院治疗的影响。我们还使用简单的Cox比例风险模型，考虑了与丧亲者和非丧亲者生存差异相关的样本选择问题。在进行这些估计之前，倾向得分法被用于对非丧亲者进行重新加权，以为丧亲者生成一个更类似随机的对照样本。我们发现，那些幸存的丧亲者比可比的非丧亲队列更有可能入院且住院时间更长。据估计，丧亲之痛平均每年会导致额外0.24（95%置信区间[0.15, 0.33]）个住院日。与之前的研究类似，我们估计丧亲者的死亡率比可比的非丧亲队列高19.2%（95%置信区间[12.5%, 26.3%]）。
