This methods report provides an overview of the redesigned National Home and Hospice Care Survey (NHHCS) conducted in 2007. NHHCS is a national probability sample survey that collects data on U.S. home health and hospice care agencies, their staffs and services, and the people they serve. The redesigned survey included computerized data collection, greater survey content, increased sample sizes for current home health care patients and hospice care discharges, and a first-ever supplemental survey called the National Home Health Aide Survey.
The 2007 NHHCS was conducted between August 2007 and February 2008. NHHCS used a two-stage probability sampling design in which agencies providing home health and/or hospice care were sampled. Then, up to 10 current patients were sampled from each home health care agency, up to 10 discharges from each hospice care agency, and a combination of up to 10 patients/discharges from each agency that provided both home health and hospice care services. In-person interviews were conducted with agency directors and their designated staff; no interviews were conducted directly with patients. The survey instrument contained agency- and person-level modules, sampling modules, and a self-administered staffing questionnaire.
Data were collected on 1036 agencies, 4683 current home health care patients, and 4733 hospice care discharges. The first-stage agency weighted response rate (for differential probabilities of selection) was 59%. The second-stage patient/discharge weighted response rate was 96%. Three public-use files were released: an agency-level file, a patient/discharge-level file, and a medication file. The files include sampling weights, which are necessary to generate national estimates, and design variables to enable users to calculate accurate standard errors.
本方法报告概述了2007年重新设计的全国居家与临终关怀护理调查（NHHCS）。NHHCS是一项全国概率抽样调查，收集有关美国家庭健康与临终关怀护理机构、其工作人员和服务以及所服务人群的数据。重新设计的调查包括计算机化数据收集、更多的调查内容、增加了当前家庭健康护理患者和临终关怀护理出院患者的样本量，以及首次进行的名为“全国家庭健康助理调查”的补充调查。
2007年NHHCS于2007年8月至2008年2月进行。NHHCS采用两阶段概率抽样设计，对提供家庭健康和/或临终关怀护理的机构进行抽样。然后，从每个家庭健康护理机构中抽取多达10名当前患者，从每个临终关怀护理机构中抽取多达10名出院患者，并从每个提供家庭健康和临终关怀护理服务的机构中抽取多达10名患者/出院患者的组合。对机构主任及其指定工作人员进行了面对面访谈；未直接对患者进行访谈。调查工具包含机构和个人层面的模块、抽样模块以及一份自行填写的人员配置问卷。
收集了1036个机构、4683名当前家庭健康护理患者和4733名临终关怀护理出院患者的数据。第一阶段机构加权回复率（针对不同的选择概率）为59%。第二阶段患者/出院加权回复率为96%。发布了三个公共使用文件：一个机构层面的文件、一个患者/出院层面的文件和一个用药文件。这些文件包括抽样权重，这是生成全国估计数所必需的，以及设计变量，以便用户能够计算准确的标准误差。
