ObjectivesInvolvement of patients and medical professionals in assessment of relative effectiveness (relative effectiveness assessment) contributes to an efficient and effective health technology assessment (HTA) process and supports acceptance and implementation of the outcome. This study aimed to analyze stakeholder involvement in assessing relative effectiveness and how the parties involved value this collaboration.MethodsThis is a document analysis of all drug assessments completed in 2019 (20) by the public HTA agency of The Netherlands, enriched with semistructured interviews with employees of the HTA agency (18) and representatives of patient (5) and medical (11) associations involved in these assessments. Data were analyzed, coded, and categorized.ResultsIn almost half of the assessments, there was no coordination with the medical associations at the start of the relative effectiveness assessment and no patient associations involved in this phase. During the assessment procedure, patient and medical associations were always asked to comment on the draft report. Nevertheless, the strict 5-day deadline that the HTA agency uses as a response period often hampered a proper response and involvement. According to interviewees of the HTA agency, this leads to a great diversity in the substantive quality of their input. Patient and medical associations indicated that the HTA agency relies too much on “paper knowledge,” which leads to a (perceived) lack of alignment with clinical practice.ConclusionsThe limited involvement results in a lack of coordination and mutual trust. Optimizing involvement of patients and medical professionals in HTA practice requires effort from all parties involved. Procedural adjustments and better coordination, especially at the start of the assessment, would probably improve cooperation. 相似文献

This study investigated how doctors communicate the uncertainties of survival prognoses to patients recently diagnosed with life‐threatening cancer, and suggests ways to improve this communication. Two hundred thirty‐eight Norwegian oncologists and general practitioners (GPs) participated in Study 1. The study included both a scenario and a survey. The scenario asked participants to respond to a hypothetical patient who wanted to know how long (s)he could be expected to live. There were marked differences in responses within both groups, but few differences between the GPs and oncologists. There was a strong reluctance among doctors to provide patients with a prognosis. Even when they were presented with a statistically well‐founded right‐skewed survival curve, only a small minority provided hope by communicating the variation in survival time. In Study 2, 177 healthy students rated their preferences for different ways of receiving information regarding the uncertainty of a survival prognosis. Participants who received an explicitly described right‐skewed survival curve believed that they would feel more hopeful. These participants also obtained a more realistic understanding of the variation in survival than those who did not receive this information. Based on the findings of the two studies and on extant psychological research, the author suggests much‐needed guidelines for communicating survival prognoses in a realistic and optimistic way to patients recently diagnosed with life‐threatening cancer. In particular, the guidelines emphasise that the doctor explains the often strongly right‐skewed variation in survival time, and thereby providing the patient with realistic hope. 相似文献
