Test–retest stability of patient experience items derived from the national GP patient survey

PURPOSE: The validity and reliability of various items on the GP Patient Survey (GPPS) survey have been reported, however stability of patient responses over time has not been tested. The purpose of this study was to determine the test-retest reliability of the core items from the GPPS. METHODS: Patients who had recently consulted participating GPs in five general practices across the South West England were sent a postal questionnaire comprising of 54 items concerning their experience of their consultation and the care they received from the GP practice. Patients returning the questionnaire within 3 weeks of mail-out were sent a second identical (retest) questionnaire. Stability of responses was assessed by raw agreement rates and Cohen's kappa (for categorical response items) and intraclass correlation coefficients and means (for ordinal response items). RESULTS: 348 of 597 Patients returned a retest questionnaire (58.3 % response rate). In comparison to the test phase, patients responding to the retest phase were older and more likely to have white British ethnicity. Raw agreement rates for the 33 categorical items ranged from 66 to 100 % (mean 88 %) while the kappa coefficients ranged from 0.00 to 1.00 (mean 0.53). Intraclass correlation coefficients for the 21 ordinal items averaged 0.67 (range 0.44-0.77). CONCLUSIONS: Formal testing of items from the national GP patient survey examining patient experience in primary care highlighted their acceptable temporal stability several weeks following a GP consultation.Funding was provided by Health Services and Delivery Research Programme (Grant No. RP-PG-0608-10050)

Instruments to assess patient satisfaction after teleconsultation and triage: a systematic review

Martina Allemann Iseli,1 Regina Kunz,2 Eva Blozik1,31Swiss Center for Telemedicine Medgate, Basel, Switzerland; 2Academy of Swiss Insurance Medicine, University of Basel, Basel, Switzerland; 3Department of Primary Medical Care, University Medical Center Hamburg–Eppendorf, Martinistrasse, Hamburg, GermanyBackground: Patient satisfaction is crucial for the acceptance, use, and adherence to recommendations from teleconsultations regarding health care requests and triage services.Objectives: Our objectives are to systematically review the literature for multidimensional instruments that measure patient satisfaction after teleconsultation and triage and to compare these for content, reliability, validity, and factor analysis.Methods: We searched Medline, the Cumulative Index to Nursing and Allied Health Literature, and PsycINFO for literature on these instruments. Two reviewers independently screened all obtained references for eligibility and extracted data from the eligible articles. The results were presented using summary tables.Results: We included 31 publications, describing 16 instruments in our review. The reporting on test development and psychometric characteristics was incomplete. The development process, described by ten of 16 instruments, included a review of the literature (n=7), patient or stakeholder interviews (n=5), and expert consultations (n=3). Four instruments evaluated factor structure, reliability, and validity; two of those four demonstrated low levels of reliability for some of their subscales.Conclusion: A majority of instruments on patient satisfaction after teleconsultation showed methodological limitations and lack rigorous evaluation. Users should carefully reflect on the content of the questionnaires and their relevance to the application. Future research should apply more rigorously established scientific standards for instrument development and psychometric evaluation.Keywords: teleconsultation, teletriage, triage, consultation, general practitioner, patient satisfaction, psychometric, evaluation, out-of-hour
