A photograph of the researcher on the invitation letter did not affect the participation rate of a postal survey: a randomized study within a trial (SWAT).

OBJECTIVE: Participant recruitment is one of the main challenges in research. It is suggested that including researcher photographs might increase participation rates, but empirical evidence is lacking. This study within a trial (SWAT) aims to assess whether invitation letters including researcher photographs increase the participation rate in the context of a survey on medical second opinions. METHODS: Through 25 local register offices in Berlin and Brandenburg (Germany), we identified a random sample of 9990 persons. We randomly assigned our sample to the intervention group (IG) receiving an invitation letter with researcher photographs and control group (CG) receiving an invitation letter without photographs in a 1:1 ratio. Our primary outcome was the participation rate. Furthermore, we compared participants to non-participants' characteristics. RESULTS: Of 9990 invitations, 9797 could be delivered (IG: 4890, CG: 4907). Of these, 1349 (13.8%) participated. There were 682/4890 (13.9%) participants in the IG and 662/4907 (13.5%) in the CG with an odds ratio of 1.030 (95% confidence interval: 0.918-1.156). Additional analyses on non-participant characteristics did not show any differences. CONCLUSION: We could not find any difference in the participation rates. Our study does not confirm the results of previous studies. The length of our questionnaire may have affected our results. TRIAL REGISTRATION: Queens University Belfast - SWAT Store, SWAT 104.

Telemedical Second Opinions in Germany: A Customer Survey of an Online Portal.

Introduction: Second medical opinions (SOs) can strengthen patients' certainty in decision making. In Germany, both personally delivered and telemedical SOs (often based on documents only) are provided. Our aim was to analyze the experiences of people who obtained telemedical SOs. We also investigated different routes of SO delivery (personally/by phone/documents only). Materials and Methods: German residents who obtained a telemedical SO via an online portal between January 2016 and February 2019 (n = 1,247) were contacted by post between August and November 2019 up to three times. The results were analyzed descriptively. Results: The 368 participants (response rate 30%) were 54% male, 95% statutory health insured, and 61 years old (median; interquartile range 51-72). Approximately 75% were (rather) satisfied with obtaining the SO via the online portal. The most preferred route of SO delivery was a personally delivered SO, which 80% would (rather) consider, followed by 70% (rather) considering SOs based on documents only and 48% (rather) considering SOs by phone. The most often mentioned advantage of telemedical SOs was independence of time and place, while the most important disadvantage was the standardized process resulting in a lack of direct and personal contact between the patient and the physician. Discussion: Although our results show that SOs (based on documents only) support patients and that patient satisfaction was high, personally delivered SOs were still preferred. Future research on the use of SOs based on documents only (in which patient population and in what situations) is needed.

Attitude toward second opinions in Germany - a survey of the general population.

BACKGROUND: Second medical opinions (SOs) can assist patients in making informed treatment decisions and improve the understanding of their diagnosis. In Germany, there are different approaches to obtain a structured SO procedure: SO programs by health insurers and SOs according to the SO Directive. Through a direct survey of the population, we aimed to assess how structured SOs should be provided to fulfil patients' needs. METHODS: A stratified sample of 9990 adults (≥18 years) living in the federal states of Berlin and Brandenburg (Germany) were initially contacted by post in April and sent a reminder in May 2020. The survey results were analyzed descriptively. RESULTS: Among 1349 participants (response rate 14%), 56% were female and the median age was 58 years (interquartile range (IQR) 44-69). Participants wanted to be informed directly and personally about the possibility of obtaining an SO (89%; 1201/1349). They preferred to be informed by their physician (93%; 1249/1349). A majority of participants would consider it important to obtain an SO for oncological indications (78%; 1049/1349). Only a subset of the participants would seek an SO via their health insurer or via an online portal (43%; 577/1349 and 16%; 221/1349). A personally delivered SO was the preferred route of SO delivery, as 97% (1305/1349) would (tend to) consider this way of obtaining an SO. Participants were asked to imagine having moderate knee pain for years, resulting in a treatment recommendation for knee joint replacement. They were requested to rate potential qualification criteria for a physician providing the SO. The criteria rated to be most important were experience with the recommended diagnosis/treatment (criterion (very) important for 93%; 1257/1349) and knowledge of the current state of research (criterion (very) important for 86%; 1158/1349). Participants were willing to travel 60 min (median; IQR 60-120) and wait 4 weeks (median; IQR 2-4) for their SO in the hypothetical case of knee pain. CONCLUSION: In general, SOs were viewed positively. We found that participants have clear preferences regarding SOs. We propose that these preferences should be taken into account in the future design and development of SO programs.
