北京海淀“1+N”养老政策体系 http://www.chebx.cn/cn/marketing/monograph/21525-the-1-n-elderly-care-policy-system-in-haidian-district-beijing http://www.chebx.cn/cn/marketing/monograph/21525-the-1-n-elderly-care-policy-system-in-haidian-district-beijing

    聚焦80岁以上高龄老人居家养老需求,创新居家养老服务模式,在街镇养老服务中心建设、养老助餐体系建设、老年人家庭适老化改造、智慧养老、环京养老圈发展等方面推进“1+N”养老政策体系在海淀落地开花。

  “1+N”养老政策体系指“1个实施意见”,即北京市推进基本养老服务体系建设的实施意见;“N个专项方案”,即社区养老服务设施布局及功能优化、居家养老服务能力提升、养老助餐服务供给、综合为老服务平台运行、养老服务人才队伍规划等专项方案。据统计,海淀区常住老年人口为63.5万人,其中80周岁及以上老年人11.6万人,占老年人口的18.3%。伴随着人口老龄化、高龄化、失能化、空巢化趋势加快,加快发展普惠性居家养老服务,满足老年人的刚性需求,已经成为区委社会工委区民政局着力开展的重要民生任务。
