Abstract：
BACKGROUND: Low response rates (RRs) can affect hospitals\' data collection costs for patient experience surveys and value-based purchasing eligibility. Most hospitals use single-mode approaches, even though sequential mixed mode (MM) yields higher RRs and perhaps better patient representativeness. Some hospitals may be reluctant to incur MM\'s potential additional cost and complexity without knowing how much RRs would increase.
OBJECTIVE: The aim of this study was to estimate the differences in RR and patient representation between MM and single-mode approaches and to identify hospital characteristics associated with the largest RR differences from MM of single-mode protocols (mail-only, phone-only).
METHODS: Patients were randomized within hospitals to one of 3 modes (mail-only, phone-only, MM).
METHODS: A total of 17,415 patients from the 51 nationally representative US hospitals participating in a randomized HCAHPS mode experiment.
RESULTS: Mail-only RRs were lowest for ages 18-24 (7%) and highest for ages 65+ (31%-35%). Phone-only RRs were 24% for ages 18-24, increasing to 37%-40% by ages 55+. MM RRs were 28% for ages 18-24, increasing to 50%-60% by ages 65-84. Lower hospital-level mail-only RRs strongly predicted greater gains from MM. For example, a hospital with a 15% mail-only RR has a predicted MM RR >40% (with >25% occurring in telephone follow-up).
CONCLUSIONS: MM increased representation of hard-to-reach (especially young adult) patients and hospital RRs in all mode experiment hospitals, especially in hospitals with low mail-only RRs.

摘要：
背景：低应答率（RR）会影响医院对患者体验调查和基于价值的购买资格的数据收集成本。大多数医院使用单一模式方法，即使序贯混合模式（MM）产生更高的RR和可能更好的患者代表性。一些医院可能不愿意承担MM的潜在额外成本和复杂性，而不知道会增加多少RR。
目的：本研究的目的是估计MM和单模式方法之间RR和患者表现的差异，并确定与单模式方案MM最大RR差异相关的医院特征（仅邮件，仅限电话)。
方法：患者在医院内随机分为3种模式之一（仅邮寄，只有电话,MM）。
方法：来自美国51家全国代表性医院的17,415名患者参与了一项随机HCAHPS模式实验。
结果：仅邮件RR在18-24岁年龄段最低（7%），在65岁以上年龄段最高（31%-35%）。18-24岁的纯电话RR为24%，到55岁以上时增加到37%-40%。18-24岁的MMRR为28％，到65-84岁增加到50％-60％。较低的医院级别的仅邮件RR强烈预测了MM的更大收益。例如,仅邮件RR为15％的医院的MMRR预测>40％（电话随访中>25％）。
结论：在所有模式实验医院中，MM增加了难以到达（尤其是年轻成人）患者和医院RR的代表，尤其是在只有邮件的Rs较低的医院。
