“…Previous studies have shown that Google search analyses are an effective tool for assessing disease trends (38), as well as understanding health information seeking behavior (28,30,32,33). In total, almost 3.5 million Google searches related to skin cancer were observed within 4 years in our study, representing 17.6% of all skin cancer-related Google searches across all of Germany (n = 19,849,230) (30).…”

“…A retrospective longitudinal study using Google AdWords Keyword Planner was carried out to identify the search volume of terms related to skin cancer between July 2014 and June 2018 in 9 large cities across Germany (Berlin, Hamburg, Munich, Cologne, Stuttgart, Nuremberg, Muenster, Magdeburg and Recklinghausen). Although Google AdWords Keyword Planner is used primarily to detect keywords for optimizing Google marketing campaigns, this tool can also be used for scientific purposes (30,32,33). The software provides monthly search volume data as estimated by Google.…”

“…One way to investigate reasons for not using skin cancer prevention measures is to focus on the interest in skin cancer among the general population (28). As the Internet is a commonly used source of health information, search engine analysis represents a novel tool for investigating the general interest in various topics (16,(28)(29)(30)(31)(32)(33). In Germany, approximately 90% of inhabitants use the Internet (34).…”

This study examined the Google search volume for skincancer-related terms in 9 German cities. Overall, 3.5 million searches related to skin cancer were observed between July 2014 and June 2018. Most of these searches focused on the identification of skin cancer (e.g. ABCD and pictures of skin cancer). In general, the number of search queries per 100,000 inhabitants was lower in larger cities, such as Berlin or Hamburg, in comparison with Stuttgart or Muenster. Analysis of the differences in search behavior between cities could help to identify areas with a high need for targeted prevention campaigns. Skin cancer is a major public health issue, which could be reduced through prevention programmes. How ever, prevention utilization is not very prevalent. It is therefore important to understand individuals' interest in skin cancer. Google AdWords Keyword Planner was used to identify the search volume of terms relating to skin cancer in 9 German cities between July 2014 and June 2018. From a total of 1,203 identified keywords, 1,047 search terms were related to skin cancer, which had a search volume of 3,460,980 queries for the study period. Most terms referred to "identifying skin can cer". For melanoma, the number of Google searches per 100,000 inhabitants correlated with the cancer registry data for melanoma incidence rates (men: r = 0.810, women: r = 0.569). Assessment of this data for the different cities further enabled identification of regional variations, which could help to identify areas with a high need for targeted prevention campaigns.

“…In addition, analyzing Internet data is useful for examining Internet behavior, interest, and people’s reactions to various incidents [27]. Studies investigating Google search volume data for the term “pruritus” in Germany have demonstrated that this method provides good insight into people’s interests and needs [30,31]. However, dermatological care differs even within Germany.…”

Background The burden of pruritus is high, especially among patients with dermatologic diseases. Identifying trends in pruritus burden and people’s medical needs is challenging, since not all affected people consult a physician. Objective The purpose of this study was to investigate pruritus search behavior trends in Germany and identify associations with weather factors. Methods Google AdWords Keyword Planner was used to quantify pruritus-related search queries in 16 German cities from August 2014 to July 2018. All identified keywords were qualitatively categorized and pruritus-related terms were descriptively analyzed. The number of search queries per 100,000 inhabitants of each city was compared to environmental factors such as temperature, humidity, particulate matter 10 micrometers or less in diameter (PM10), and sunshine duration to investigate potential correlations. Results We included 1150 pruritus-related keywords, which resulted in 2,851,290 queries. “Pruritus” (n=115,680) and “anal pruritus” (n=102,390) were the most-searched-for keywords. Nearly half of all queries were related to the category localization , with Berlin and Munich having a comparatively high proportion of people that searched for pruritus in the genital and anal areas. People searched more frequently for information on chronic compared to acute pruritus. The most populated cities had the lowest number of queries per 100,000 inhabitants (Berlin, n=13,641; Hamburg, n=18,303; and Munich, n=21,363), while smaller cities (Kiel, n=35,027; and Freiburg, n=39,501) had the highest. Temperature had a greater effect on search query number (beta -7.94, 95% CI -10.74 to -5.15) than did PM10 (beta -5.13, 95% CI -7.04 to -3.22), humidity (beta 4.73, 95% CI 2.70 to 6.75), or sunshine duration (beta 0.66, 95% CI 0.36 to 0.97). The highest relative number of search queries occurred during the winter (ie, December to February). Conclusions By taking into account the study results, Google data analysis helps to examine people’s search frequency, behavior, and interest across cities and regions. The results indicated a general increase in search queries during the winter as well as differences across cities located in the same region; for example, there was a decline in search volume in Saarbrucken, while there were increases in Cologne, Frankfurt, and Dortmund. In addition, the detected correlation between search volume and weather data seems to be valuable in predicting an increase in pruritus burden, since a significant association with rising humidity and sunshine duration, as well as declining temperature and PM10, was found. Accordingly, this is an unconventional and inexpensive method to identify search behavior trends and respective inhabitants’ needs.

Die bisherige Forschung konnte zeigen, dass die Allgemeinbevölkerung häufig Suchmaschinen verwendet, um sich über gesundheitsbezogene Themen zu informieren [11][12][13].

Pruritus in Deutschland – eine Google-Suchmaschinenanalyse

Abstract: With its unconventional methodology, a Google search engine analysis, this study allows a rough estimation of the medical need of pruritus in the German general population, which seems to be higher than expected. Especially pruritus in the anal area was identified as an unmet medical need.
