Show moreBackground: Digital triage tools for sexually transmitted infection (STI) testing can potentially be used as a substitute for the triage that general practitioners (GPs) perform to lower their work pressure. The studied tool is based on medical guidelines. The same guidelines support GPs' decision-making process. However, research has shown that GPs make decisions from a holistic perspective and, therefore, do not always adhere to those guidelines. To have a high-quality digital triage tool that results in an efficient care process, it is important to learn more about GPs' decision-making process. Objective: The first objective was to identify whether the advice of the studied digital triage tool aligned with GPs' daily medical practice. The second objective was to learn which factors influence GPs' decisions regarding referral for diagnostic testing. In addition, this study provides insights into GPs' decision-making process. Methods: A qualitative vignette-based study using semistructured interviews was conducted. In total, 6 vignettes representing patient cases were discussed with the participants (GPs). The participants needed to think aloud whether they would advise an STI test for the patient and why. A thematic analysis was conducted on the transcripts of the interviews. The vignette patient cases were also passed through the digital triage tool, resulting in advice to test or not for an STI. A comparison was made between the advice of the tool and that of the participants. Results: In total, 10 interviews were conducted. Participants (GPs) had a mean age of 48.30 (SD 11.88) years. For 3 vignettes, the advice of the digital triage tool and of all participants was the same. In those vignettes, the patients' risk factors were sufficiently clear for the participants to advise the same as the digital tool. For 3 vignettes, the advice of the digital tool differed from that of the participants. Patient-related factors that influenced the participants' decision-making process were the patient's anxiety, young age, and willingness to be tested. Participants would test at a lower threshold than the triage tool because of those factors. Sometimes, participants wanted more information than was provided in the vignette or would like to conduct a physical examination. These elements were not part of the digital triage tool. Conclusions: The advice to conduct a diagnostic STI test differed between a digital triage tool and GPs. The digital triage tool considered only medical guidelines, whereas GPs were open to discussion reasoning from a holistic perspective. The GPs' decision-making process was influenced by patients' anxiety, willingness to be tested, and age. On the basis of these results, we believe that the digital triage tool for STI testing could support GPs and even replace consultations in the future. Further research must substantiate how this can be done safely. Show less

Show moreThis dissertation contains the results of an RCT into the effectiveness of an online self-help intervention for people living with HIV (PLWH) and depressive symptoms. Many PLWH suffer from depressive symptoms. Online interventions to treat depression may have benefits, such as less perceived stigma, a large reach and high accessibility. The online self-help intervention that we investigated is based on cognitive behavioral therapy and contains 4 components: stimulating activities, relaxation exercises, changing negative thoughts and goal attainment. Two meta-analyses were conducted and the results point to the effectiveness of psychosocial interventions for PLWH to improve depressive symptoms, anxiety symptoms, quality of life, psychological well-being, and medication adherence. The most important result of the RCT was that the intervention together with telephone coaching is effective in reducing depressive symptoms, compared to an attention-only control group. It was also found that the intervention may be effective for all PLWH, regardless of certain baseline characteristics. Furthermore, behavioral activation and goal reengagement were found to be mediators of the intervention effect. Also, the intervention is likely to be cost-effective compared to attention only. As eHealth interventions have benefits compared to face-to-face interventions, they should be more widely implemented in the mental healthcare for PLWH. Show less
