Dealing with health information and taking care of one’s own health are key aspects of health literacy and a difficulty for nearly half of the population in Europe. Limited health literacy often results in poorer health outcomes. Health literacy is a fundamental health determinant, and its improvement provides great potential for addressing public health challenges. Health care organizations play an important role in improving population’s health literacy. Health literate health care organizations facilitate access, understanding and use of health information and decrease the demands and complexities of the health care system. Few efforts have been taken so far to promote organizational health literacy, especially in German-speaking countries. This project aimed at developing a self-assessment tool, which enables primary care organizations to assess and improve their level of health literacy. The self-assessment tool was developed and evaluated with general practitioners and community care organizations in Switzerland. Here the participative development process, outcomes and the three modules of the self-assessment tool are presented: (1) manual with detailed introduction and instruction, (2) checklist for self-assessment of organizational health literacy and (3) handbook with measures for improvement. The aim of this tool is that organizations are able to identify the need for action, plan and implement improvement measures.

Objectives: We engaged patients with systemic sclerosis (SSc) and healthcare professionals to assess electronic health (eHealth) literacy and needs relating to web-based support using internet-based information and communication technologies (ICT). Methods: We employed an explanatory sequential mixed methods design. First, we conducted a cross-sectional survey in patients (n=101) and professionals (n=47). Next, we conducted three focus groups with patients, family members and professionals (n=17). Results: Of patients, 89.1% used ICT at least weekly for private communication. Patients reported relatively high comprehension of eHealth information ( x ¯ =6.7, 95% CI: 6.2 to 7.3, range 1–10), yet were less confident evaluating information reliability ( x ¯ =5.8, 95% CI: 5.1 to 6.4) and finding eHealth apps ( x ¯ =4.8, 95% CI: 4.2 to 5.4). Patients and professionals reported little experience with web-based self-management support. Focus groups revealed ‘considering non-ICT-accessible groups’ and ‘fitting patients’ and professionals’ technology’ as crucial for acceptability. In relation to understanding/appraising eHealth, participants highlighted that general SSc information is not tailored to individual’s disease course. Recommendations included ‘providing timely, understandable and safe information’ and ‘empowering end-users in ICT and health decision-making skills’. Professionals expressed concerns about lacking resources. Patients were concerned about data security and person-centredness. Key eHealth drivers included ‘addressing end-user perceptions’ and ‘putting people at the centre of technology’. Conclusions: Patients and professionals need education/training to support uptake of eHealth resources. Key elements include guiding patients to timely/reliable information and using eHealth to optimise patient–provider communication. Design that is responsive to end-users’ needs and considers individuals with limited eHealth literacy and/or ICT access appears to be critical for acceptability.

Background: Hepatitis C virus reinfections in HIV-positive men-who-have-sex-with-men (MSM) challenge the effectiveness of antiviral treatment. To fight this problem, an adapted sexual risk reduction intervention was implemented within a hepatitis C treatment trial. Following this, the current study had two aims and describes 1) how the program was received by participants; and 2) their responses to the program regarding sexual risk taking. Based on the participants’ input, we hoped to judge the intervention’s potential for scale-up. Methods: Seventeen participants who received the sexual risk reduction intervention in addition to hepatitis C treatment were recruited for semi-structured interviews six to 12 months post-intervention. We evaluated the responses via reflexive thematic analysis and applied the concept of sense-making. Results: Giving hepatitis C a place and living without it again illustrates how participants received the program and how their experiences were altered by the impact of sense-making. Based on their responses, we allocated participants to three groups: 1. Avoid risks: get rid of hepatitis C for life. For these men, hepatitis C remained a life-threatening disease: they actively modified their risk behavior and felt supported by the intervention in maintaining their behavioral changes. 2. Minimize risks: live as long as possible without hepatitis C. In contrast to group 1, these men saw hepatitis C as a manageable disease. The intervention facilitated reflection on risks and how to develop behavioral changes that suited them individually. 3. Accept risks; live with the risk of hepatitis C. These men perceived behavioral changes as much more difficult than “easy” medical treatment. They expected to either undergo repeated rounds of treatment or stay HCV re-infected. Conclusion: These results illustrate the diversity of men’s responses and their decisions regarding sexual risk behavior after participating in a combination of antiviral treatment and a sexual risk reduction intervention. Two major aspects were identified: 1) Teachable moments, particularly at the time of diagnosis/treatment, could offer an opportunity to develop openness for behavioral change; 2) adapting sexual risk reduction interventions to sense-making patterns could help to improve its effectiveness. Support for reducing infection risk and raising awareness of preventative measures are additional benefits. Trial registration: Clinical Trial Number: NCT02785666, 30.05.2016.

Organizational health literacy (OHL) is crucial for public health, in turn health care organizations play vital roles in improving populations’ health literacy. Therefore, the aim of this qualitative study was to explore how the organizational health literacy self-assessment tool (OHL Self-AsseT) was implemented, used, and understood by primary care teams from a network of general practices and a Home Care Service Organization in Zurich, Switzerland. Reflexive thematic analysis with a constructivist orientation was used to analyze data from 19 interviews pre- and post-OHL Self-AsseT use. Normalization Process Theory supported structuring of inductively developed themes. Findings show that the participants experienced working with the OHL Self-AsseT meaningful, as it helped with “Addressing OHL construction sites” so that they could “build momentum for change”. The experience of “Succeeding together in construction” led to a “feeling of team-efficacy during change”. Practical use of the tool and/or discussions about OHL led to a growing conceptual understanding, which was described as “Using a construction plan–making sense of ongoing OHL activities”. To conclude, the OHL Self-AsseT encouraged teams to initiate change, led to greater team-efficacy and supported the construction of OHL. Improved implementation strategies will support this intervention’s scale-up as a base for effectiveness testing.

Primary care organizations offer a suitable setting to promote organizational health literacy (OHL) since they are a crucial interface for patients and clients. However, a clear picture on the OHL situation in primary care is lacking. The aim of this study was to assess OHL in Swiss primary care organizations by evaluating (i) how they rate their level of OHL and which improvement measures they accordingly plan (organizational level), (ii) what knowledge and attitudes among health professionals in primary care regarding OHL exist (individual level) and (iii) how teams working in general practitioners’ practices and a home care service organization differ regarding OHL (organizational and individual level). The research design included an online survey (N = 74, health professionals) on the individual level and a checklist and intervention documentation (N = 10, primary care teams) on the organizational level. The study reveals a crucial demand regarding organizationally embedded OHL practices in the participating primary care teams, despite a rather comprehensive understanding of the concept. The greatest need for action was identified in strengthening health literacy of staff members, which underlines the necessity to develop interventions to systematically strengthen the health literacy of health professionals.
