Disease-Related Internet Use and its Relevance to the Patient-Physician Relationship in Atopic Dermatitis: A Cross-Sectional Study in Germany

Background: Health-related internet use presents both opportunities and challenges for patients and physicians and requires a comprehensive understanding to improve individual health care in atopic dermatitis (AD). Objective: To explore differences between regular and irregular disease-related internet users, reasons for disease-related internet use, and its relevance to the patient-physician relationship in AD. Methods: This cross-sectional study recruited 221 adults with AD online and from a German university clinic between August 2021 and February 2022. The questionnaire queried sociodemographic and disease-related information, reasons for and against using the internet, types of channels used, and the impact on the patient-physician relationship. Participants were categorized as regular (≥once per month) and irregular ( Collapse

Navigating through the healthcare system with atopic dermatitis: Analysing patient journeys in Germany

BACKGROUND

Atopic dermatitis (AD), which can significantly impact quality of life, is a complex, heterogeneous skin disease affecting all ages and therefore can lead to very different patient journeys. Understanding the patient journey within the healthcare system is essential for improving care outcomes.

OBJECTIVES

To explore the patient journey of individuals with AD in Germany, with a specific focus on the utilization of Internet resources throughout this process.

METHODS

A cross-sectional study using a self-administered questionnaire was conducted from June 2021 to February 2022. Participants were recruited from dermatology private practices, a university hospital and online platforms.

RESULTS

The study included 276 participants (62.3% female; mean age: 46.3 ± 18.4 years; mean disease duration: 26.9 ± 17.5 years; mean DLQ Index: 10.0 ± 5.6). Around 191 participants were currently receiving medical treatment, with 9.1% receiving biologic therapy. Most of the people initially contacted a GP (42.4%) and were diagnosed by a dermatologist first (57.6%). Around 47.1% were currently in treatment by a dermatologist, seeking dermatological care on average 4.5 times a year. Almost all individuals (86.2%) have already consulted more than one physician during their patient journey. Overall, participants consulted a median of five physicians, while those with severe AD consulted a median of six physicians. Initial symptoms to diagnosis and between consulting two different physicians both had a median duration of 6 months. Dissatisfaction with treatment outcomes emerged as a common reason for changing physicians. Approximately 76.4% of participants used the Internet for disease-related information, primarily relying on Google. Overall, 63% found the information quality unsatisfactory.

CONCLUSION

The study underlines the widespread utilization of medical treatment and the proactive healthcare-seeking behaviour during a long patient journey. Dissatisfaction with treatment outcomes, alternative medicine and the quality of the Internet sources emphasize the potential for improving the comprehensive disease management to improve care outcomes.

Burden of atopic dermatitis in Europe: A population-centred approach leveraging web search data in 21 European countries

BACKGROUND

The complexity, high prevalence, and substantial personal and socioeconomic burden collectively render atopic dermatitis (AD) a major public health concern. Using crowdsourced Internet data has the potential to provide unique insights into this concern, as demonstrated by several previous studies. However, a comprehensive comparison across European countries remains lacking.

OBJECTIVES

The study aimed to investigate AD-related web searches across Europe to assess spatiotemporal variations and associations between disease-related and external factors.

METHODS

AD-related web search data were extracted for 21 European countries between February 2019 and January 2023. Descriptive analysis and autocorrelation functions were performed to examine spatiotemporal patterns. Correlations (r) were used to evaluate the associations between web searches and disease-related, socioeconomic and meteorological data.

RESULTS

Over 241 million AD-related web searches were identified, with search volume varying substantially among European countries (p < 0.001) and correlating with AD prevalence and disease burden (both r = 0.51, p = 0.019). Search volume increased between 2019 and 2023 in all countries and seasonally peaked in January and March. Negative correlations with median population age (r = -0.46, p = 0.039), number of general practitioners (r = -0.29, p = 0.226) and specialists (r = -0.27, p = 0.270) were observed. Moderate to strong correlations were found between search volume and cold, humid and windy weather with fewer sunshine hours, while higher online interest typically occurred 1-3 months after such weather conditions.

CONCLUSION

The study highlights the great potential of online crowdsourced data analysis, for example, to investigate the impact of climate change or to identify unmet needs at a population level. Furthermore, the growing online interest in AD and the corresponding seasonal peaks emphasize the necessity of adapting treatment plans, intensifying public health campaigns, and disseminating reliable online information by governments and healthcare providers, especially during these periods.

[Web search data as health data? : Geographic differences, temporal trends, and topics of interest from internet search engine analyses in Germany]

BACKGROUND

Limited timely, cost-effective, and regional availability of healthcare data is considered one of the limiting factors for timely analyses in the field of health services research and thus for healthcare delivery to the general population. Thus, Internet search engine analyses are coming into focus in this context.

OBJECTIVES

What contribution can data on the volume of Internet searches for various diseases make to the health care of the German population? Where is the potential and where are the limitations?

METHODS

A review of the current literature and a selective overview of Internet search engine analyses of dermatological, allergological, and infectious diseases published in the last 4 years in Germany were performed.

RESULTS

By analyzing web search data, temporal developments such as seasonality, months with the highest interest, and geographical differences can be mapped at the national, state (Bundesländer), and city level and major points of interest (e.g., skin cancer of the eye or anal itching) regarding a certain health topic can be identified. In addition, some studies were able to show correlations between search volume and external factors (e.g., temperature, care structure) and to registered cases (e.g., skin cancer, Lyme disease).

CONCLUSION

Web search data, given the limitations noted, are able to directly provide spatiotemporal mapping regarding the needs of the Internet-using population. They are particularly useful in situations where traditional health data are limited or unavailable.
