Patients' use of the Internet for pain-related medical information

Objective

Patients increasingly use the Internet for medical information. For doctor–patient communication it is important to gain insight into the use and impact of medical Internet searches of patients. This study aims to evaluate patients’ use of the Internet for information about their pain problem.

Methods

A self-administered survey on pain-related Internet use was sent to 200 new patients attending a university pain center. The response rate was 61%.

Results

Half of all respondents used the Internet for medical information and a smaller percentage (39%) searched for specific information about pain. Patients found information on the Internet to be of good quality and quite easy to find and understand. In general, Respondents did not learn anything new. The on-line medical information confirmed what they already knew. Less than half of the respondents discussed information from the Internet with their physician.

Conclusion

Half of all patients used the Internet for medical information. Patients are reasonably certain that the information is accurate and reliable, while this may not always be the case.

Practice implications

Physicians should inquire about patients’ use of various sources of information (such as the Internet) and offer to clarify any questions or concerns that arise from that use.     

Using Internet search engines to obtain medical information: a comparative study

Background

The Internet has become one of the most important means to obtain health and medical information. It is often the first step in checking for basic information about a disease and its treatment. The search results are often useful to general users. Various search engines such as Google, Yahoo!, Bing, and Ask.com can play an important role in obtaining medical information for both medical professionals and lay people. However, the usability and effectiveness of various search engines for medical information have not been comprehensively compared and evaluated.

Objective

To compare major Internet search engines in their usability of obtaining medical and health information.

Methods

We applied usability testing as a software engineering technique and a standard industry practice to compare the four major search engines (Google, Yahoo!, Bing, and Ask.com) in obtaining health and medical information. For this purpose, we searched the keyword breast cancer in Google, Yahoo!, Bing, and Ask.com and saved the results of the top 200 links from each search engine. We combined nonredundant links from the four search engines and gave them to volunteer users in an alphabetical order. The volunteer users evaluated the websites and scored each website from 0 to 10 (lowest to highest) based on the usefulness of the content relevant to breast cancer. A medical expert identified six well-known websites related to breast cancer in advance as standards. We also used five keywords associated with breast cancer defined in the latest release of Systematized Nomenclature of Medicine-Clinical Terms (SNOMED CT) and analyzed their occurrence in the websites.

Results

Each search engine provided rich information related to breast cancer in the search results. All six standard websites were among the top 30 in search results of all four search engines. Google had the best search validity (in terms of whether a website could be opened), followed by Bing, Ask.com, and Yahoo!. The search results highly overlapped between the search engines, and the overlap between any two search engines was about half or more. On the other hand, each search engine emphasized various types of content differently. In terms of user satisfaction analysis, volunteer users scored Bing the highest for its usefulness, followed by Yahoo!, Google, and Ask.com.

Conclusions

Google, Yahoo!, Bing, and Ask.com are by and large effective search engines for helping lay users get health and medical information. Nevertheless, the current ranking methods have some pitfalls and there is room for improvement to help users get more accurate and useful information. We suggest that search engine users explore multiple search engines to search different types of health information and medical knowledge for their own needs and get a professional consultation if necessary.

Specialized medical search-engines are no better than general search-engines in sourcing consumer information about androgen deficiency

BACKGROUND: The Internet provides consumers with access to online health information; however, identifying relevant and valid information can be problematic. Our objectives were firstly to investigate the efficiency of search-engines, and then to assess the quality of online information pertaining to androgen deficiency in the ageing male (ADAM). METHODS: Keyword searches were performed on nine search-engines (four general and five medical) to identify website information regarding ADAM. Search-engine efficiency was compared by percentage of relevant websites obtained via each search-engine. The quality of information published on each website was assessed using the DISCERN rating tool. RESULTS: Of 4927 websites searched, 47 (1.44%) and 10 (0.60%) relevant websites were identified by general and medical search-engines respectively. The overall quality of online information on ADAM was poor. The quality of websites retrieved using medical search-engines did not differ significantly from those retrieved by general search-engines. CONCLUSION: Despite the poor quality of online information relating to ADAM, it is evident that medical search-engines are no better than general search-engines in sourcing consumer information relevant to ADAM.
