Research on the effect of survey timing on patient-reported experiences and patient satisfaction with health services has produced contradictory results. The objective of this study was thus to assess the association between survey timing and patient-reported experiences with hospitals.
Secondary analyses of a national inpatient experience survey including 63 hospitals in the 5 health regions in Norway during the autumn of 2006. 10,912 (45%) patients answered a postal questionnaire after their discharge from hospital. Non-respondents were sent a reminder after 4 weeks. Multilevel linear regression analysis was used to assess the association between survey timing and patient-reported experiences, both bivariate analysis and multivariate analysis controlling for other predictors of patient experiences.
Multivariate multilevel regression analysis revealed that survey time was significantly and negatively related to three of six patient-reported experience scales: doctor services (Beta = -0.424, p< 0.05), information about examinations (Beta = -0.566, p < 0.05) and organization (Beta = -0.528, p < 0.05). Patient age, self-perceived health and type of admission were significantly related to all patient-reported experience scales (better experiences with higher age, better health and routine admission), and all other predictors had at least one significant association with patient-reported experiences.
Survey time was significantly and negatively related to three of the six scales for patient-reported experiences with hospitals. Large differences in survey time across hospitals could be problematic for between-hospital comparisons, implying that survey time should be considered as a potential adjustment factor. More research is needed on this topic, including studies with other population groups, other data collection modes and a longer time span.
关于调查时间对患者报告的健康服务体验和满意度的影响的研究结果相互矛盾。因此，本研究旨在评估调查时间与患者对医院的报告体验之间的关系。
对包括挪威 5 个卫生区域的 63 家医院在内的全国住院患者体验调查的二次分析。2006 年秋季，出院后有 10912 名（45%）患者回答了邮寄问卷。4 周后未回复者会收到提醒。使用多水平线性回归分析评估调查时间与患者报告体验之间的关系，包括两变量分析和控制患者体验其他预测因素的多变量分析。
多变量多层次回归分析显示，调查时间与六个患者报告体验量表中的三个呈显著负相关：医生服务（β=-0.424，p<0.05）、检查信息（β=-0.566，p<0.05）和组织（β=-0.528，p<0.05）。患者年龄、自我感知健康和入院类型与所有患者报告体验量表显著相关（年龄较大、健康状况较好和常规入院的体验较好），所有其他预测因素与患者报告体验至少有一个显著关联。
调查时间与患者对医院的报告体验的六个量表中的三个呈显著负相关。医院之间的调查时间差异很大，这可能会对医院间的比较产生问题，这意味着调查时间应被视为潜在的调整因素。需要对此主题进行更多研究，包括对其他人群组、其他数据收集模式和更长时间跨度的研究。
