Use of the internet for self-education by patients with prostate cancer

Cancer-related fatigue: Quality, credibility, usability, and readability of information on websites of health care institutions in Germany

OBJECTIVES

This study aimed to portray available information on cancer-related fatigue on German health care institution websites considering the idea of patient empowerment.

METHODS

Based on website quality criteria, we developed a website-rating tool comprising 18 items. Descriptive analyses, a KruskalWallis test, and corresponding post hoc tests comparing rating sum scores between institution groups were performed.

RESULTS

Websites of 283 systematically compiled health care institutions were included in the rating. Cancer-related fatigue was introduced on 21.9% and detailed information was provided on 27.9% of the websites. Information material was offered on 9.2% of the websites, while fatigue treatment offers were presented on 21.6% of the websites. The rating sum scores differed between institution groups (p < 0.001), with Comprehensive Cancer Centers scoring significantly higher than the others.

CONCLUSION

The rating revealed an overall sparse provision of information, with fatigue being addressed on less than half of the websites.

PRACTICE IMPLICATIONS

For patients who have access to at least one introduction about fatigue, institutions need to extend their websites. Patients could further be referred to external institutions or information booklets. The naming of contact persons may help linking patients to providers.

Can ChatGPT, an Artificial Intelligence Language Model, Provide Accurate and High-quality Patient Information on Prostate Cancer?

OBJECTIVE

To evaluate the performance of ChatGPT, an artificial intelligence (AI) language model, in providing patient information on prostate cancer, and to compare the accuracy, similarity, and quality of the information to a reference source.

METHODS

Patient information material on prostate cancer was used as a reference source from the website of the European Association of Urology Patient Information. This was used to generate 59 queries. The accuracy of the model's content was determined with F1, precision, and recall scores. The similarity was assessed with cosine similarity, and the quality was evaluated using a 5-point Likert scale named General Quality Score (GQS).

RESULTS

ChatGPT was able to respond to all prostate cancer-related queries. The average F1 score was 0.426 (range: 0-1), precision score was 0.349 (range: 0-1), recall score was 0.549 (range: 0-1), and cosine similarity was 0.609 (range: 0-1). The average GQS was 3.62 ± 0.49 (range: 1-5), with no answers achieving the maximum GQS of 5. While ChatGPT produced a larger amount of information compared to the reference, the accuracy and quality of the content were not optimal, with all scores indicating need for improvement in the model's performance.

CONCLUSION

Caution should be exercised when using ChatGPT as a patient information source for prostate cancer due to limitations in its performance, which may lead to inaccuracies and potential misunderstandings. Further studies, using different topics and language models, are needed to fully understand the capabilities and limitations of AI-generated patient information.

Impact of COVID-19 on Online Interest in Urologic Conditions: An Analysis of Google Trends

Background

With COVID-19 leading to several isolation measures for preventative care, health care utilization, especially within urology, decreased substantially. The impact of COVID-19 on the population’s interests in urologic conditions remains to be established. By using the platform of Google Trends, which allows search behaviors and interest in healthcare topics to be quantified over time, we investigated the impact of COVID-19 on online search behaviors relating to common urologic conditions in the US.

Methods

The platform of Google Trends was utilized to analyze online interest in twelve common urologic conditions in the US from October 1, 2018 to August 1, 2021 (divided into “pre-COVID” and “COVID” periods at March 1, 2020). Search volume index (SVI), a measure of relative search volume on Google, data sets for the US, top queried and populated states, rising queries, and top queries were retrieved and analyzed for all conditions. Pre-COVID and COVID median SVIs were compared using the Mann Whitney U test, and correlations were analyzed using Spearman’s rank-order correlation test.

Results

For all twelve urologic conditions, rising and top queries were often related to symptoms, treatments, and COVID-19. COVID showed higher SVIs for erectile dysfunction (p=0.04) and lower SVIs for bladder cancer (p<0.01), hematuria (p<0.01), kidney cancer (p<0.01), kidney stones (p=0.03), and prostate cancer (p<0.01). Correlations to COVID-19 searches were seen for bladder cancer (R_S=-0.36, p<0.01), erectile dysfunction (R_S=0.20, p=0.04), hematuria (R_S=-0.31, p<0.01), overactive bladder (R_S=-0.23, p=0.04), and prostate cancer (R_S=-0.33, p<0.01). No correlations were found for benign prostatic hyperplasia, interstitial cystitis, low testosterone, urinary incontinence, and urinary tract infections.

Conclusions

Online interest in many urologic conditions, especially cancers, decreased during COVID. Given the internet’s increasing role in healthcare, a reduced interest could translate to delayed diagnosis and treatment of these conditions. Only erectile dysfunction showed increasing interest, potentially due to research or misinformation linking it to COVID-19.

The influence of online health information on health decisions: A systematic review

OBJECTIVES

This systematic review assessed the influence of online health information (OHI) search behaviour on health and medical decisions.

METHODS

Eligible studies were identified by searching electronic databases PubMed, Scopus, and CINAHL in February 2020 for studies reporting OHI search behaviour and its influence on health decisions. Information was extracted pertaining to either consumers' (self-reported) perceptions of the influence of OHI on decision-making or the association between online search behaviour and health decision-making.

RESULTS

A total of 3995 articles were screened, with 48 included in the final analysis. The reviewed studies indicated that OHI assisted in making subsequent health related decisions such as asking questions during a consultation, increased professional visits, improved adherence to the advice of a physician, being more compliant with taking medication, and improved self-care.

CONCLUSION

Consumers largely used OHI to support information provided by their physicians. The strength of the patient-provider relationship was considered important in moderating the potential negative outcomes of OHI.

PRACTICE IMPLICATIONS

Health care systems have a unique opportunity to direct OHI search behaviours towards empowering consumers to engage as an informed, active and joint decision-maker in their own health care.

"Dr. Google, I am in Pain"-Global Internet Searches Associated with Pain: A Retrospective Analysis of Google Trends Data

We aimed to rank the most common locations of pain among Google users globally and locally and analyze secular and seasonal trends in pain-related searches in the years 2004–2019. We used data generated by Google Trends (GT) to identify and analyze global interest in topics (n = 24) related to locations of pain and how these progressed over time. We analyzed secular trends and time series decomposition to identify seasonal variations. We also calculated the interest in all topics with reference to the relative search volume (RSV) of “Abdominal pain”. Google users were most commonly interested in “Headache” (1.30 [times more frequently than “Abdominal pain”]), “Abdominal pain” (1.00), and “Back pain” (0.84). “Headache” was the most frequent search term in n = 41 countries, while “Abdominal pain” was the most frequent term in n = 27 countries. The interest in all pain-related topics except “Dyspareunia” increased over time. The sharpest increase was observed for “Abdominal pain” (5.67 RSV/year), and “Toothache” (5.52 RSV/year). Most of the topics revealed seasonal variations. Among pain-related topics, “Headache,” “Abdominal pain,” and “Back pain” interested most Google users. GT is a novel tool that allows retrospective investigation of complaints among Internet users.

'Prostate Cancer' Information on the Internet: Fact or Fiction?

Background/Aims

In today's information era, patients often seek information regarding health using the internet. We assessed reliability and validity of internet information regarding 'prostate cancer'.

Methods

Search term 'prostate cancer' used on Google website (June 2017). Critical analysis was performed on first 100 hits using JAMA benchmarks, DISCERN score, Health on the Net.

Results

33 500 000 hits returned. Top 100 hits were critically analyzed. Ten links [duplicate links (n = 7), book reviews (n = 1), dead sites (n = 2)] were excluded, therefore 90 were analyzed. Subcategories assessed included: commercial (53.33%), university/medical center (24.44%), government (13.33%); non-governmental/ non-profit organizations (8.89%). Sub-type of information content assessed included: factual (74.44%), clinical trials (18.89%); stories (5.56%); question and answer (1.11%). Website rated as HONcode seal positive (14,44%) or seal negative (85,56%). Website content based on JAMA benchmarks: 0 benchmarks (4.44%), 1 benchmark (16.67%), 2 benchmarks (34.44%), 3 benchmarks (27.78%), 4 benchmarks (16.67%). DISCERN score rated: 'low' score (16-32) = 12 websites (13.33%), 'moderate' score (33-64 points) = 68 websites (75.56%), 'high' score (≥ 65 points) = 10 websites (11.11%).

Conclusion

Critical assessment of 'Prostate Cancer' information on the internet, showed that overall quality was observed to be accurate, however majority of individual websites are unreliable as a source of information by itself for patients. Doctors and patients need to be aware of this 'quality vs quantity' discrepancy when sourcing PCa information on the internet.

Are the Internet users concerned about molar incisor hypomineralization? An infoveillance study

BACKGROUND

Molar incisor hypomineralization (MIH) is a developmental enamel defect characterized by well-demarcated discolorations frequently detected in molars, causing pain and esthetic alterations.

AIM

To assess the interests of Google users on MIH-related information.

DESIGN

Digital data were collected in Google Trends through two search strategies, 'molar incisor hypomineralization' (topic) and 'MIH' (search term), between January 2004 and November 2018. ARIMA models were applied to analyze trends of curves and to predict the activity of Google users during 12 months. Autocorrelation and partial autocorrelation (ACF/PACF) plots were used to detect trends in the variation of relative search volume (RSV) related to search strategies over time. The most popular queries were analyzed qualitatively, whereas geographical heat maps were retrieved to determine search volumes according to countries (P < .05).

RESULTS

Gradual increasing trends were detected, with forecasts indicating similar levels of RSVs to the period between December 2017 and November 2018. Most popular queries and topics were associated with MIH diagnosis, being retrieved predominantly in European countries.

CONCLUSIONS

The activity of Google users related to this condition is maintained low, with a reduced intensification over time, suggesting that the awareness on MIH is probably confined to dentists and affected people worldwide.

The impact of cancer information online on cancer fatalism: education and eHealth literacy as moderators

One critical yet understudied concept associated with cancer information is cancer fatalism, i.e. deterministic thoughts about the cause of cancer, the inability to prevent it and the unavoidability of death upon diagnosis. The aim of this study is to understand how information seeking about cancer online influences cancer fatalism and whether and to what extent education and eHealth literacy moderate the relationship between them. Findings from an online survey of a nationally representative sample in the United States (N = 578) showed differential impacts of using the internet to search for information about cancer among the more and the less educated. For the less educated, more exposure to information about cancer via medical and health websites led to an increased level of cancer fatalism, whereas among the more educated, greater exposure lowered cancer fatalism. These differences were explained by the fact that the more educated were equipped with a higher level of eHealth literacy skills than the less educated. Findings show that only when one has necessary skills to apply digital resources can those resources help mitigate cancer fatalism. We suggest the need to enhance eHealth literacy skills among the less educated to reduce cancer fatalism.

'Dr Google': trends in online interest in prostate cancer screening, diagnosis and treatment

OBJECTIVES

To examine trends in online search behaviours related to prostate cancer on a national and regional scale using a dominant major search engine.

MATERIALS AND METHODS

Google Trends was queried using the terms 'prostate cancer', 'prostate-specific antigen' (PSA), and 'prostate biopsy' between January 2004 and January 2019. Search volume index (SVI), a measure of relative search volume on Google, was obtained for all terms and examined by region and time period: pre-US Preventive Services Task Force (USPSTF) Grade D draft recommendation on PSA screening; during the active Grade D recommendation; and after publication of the recent Grade C draft recommendation.

RESULTS

Online interest in PSA screening differed by time period (P < 0.01). The SVI for PSA screening was greater pre-Grade D draft recommendation (82.7) compared to during the recommendation (74.5), while the SVI for PSA screening was higher post-Grade C draft recommendation (90.4) compared to both prior time periods. Similar results were observed for prostate biopsy and prostate cancer searches. At the US state level, online interest in prostate cancer was highest in South Carolina (SVI 100) and lowest in Hawaii (SVI 64). For prostate cancer treatment options, online interest in cryotherapy, prostatectomy and prostate cancer surgery overall increased, while searches for active surveillance, external beam radiation, brachytherapy and high-intensity focused ultrasonography remained stable.

CONCLUSION

Online interest in prostate cancer has changed over time, particularly in accordance with USPSTF screening guidelines. Google Trends may be a useful tool in tracking public interest in prostate cancer screening, diagnosis, and treatment, especially as it relates to major shifts in practice guidelines.

What to Consider in a Culturally Tailored Technology-Based Intervention?

The purpose of this article is to identify practical issues in implementing a culturally tailored technology-based intervention among Asian American survivors of breast cancer. In a large-scale technology-based breast cancer intervention study, research team members wrote memos on issues in implementing a culturally tailored technology-based intervention and plausible reasons for the issues. Then, the content of the research diaries was analyzed, along with written records of the research team. The practical issues found in the research process included those related to (1) technology literacy and preferences; (2) language issues; (3) cultural attitudes, beliefs, and values; (4) intervention staff competence; (5) security and confidentiality issues; and (6) time and geographical constraints. Based on the issues, several recommendations are proposed for future research using culturally tailored technology-based interventions among racial and ethnic minorities.

Telemedicine and prostate cancer survivorship: a narrative review

Prostate cancer survivors have unique needs that encompass diagnosis and treatment-related side effects. The provision of services for prostate cancer survivors is often limited by resources, time constraints in traditional clinic visits, payment, and patient and provider comfort with discussion of sensitive topics including sexual and urinary health, both of which are largely impacted by treatment. Telemedicine, the remote delivery of health care services using telephone, mobile, web, and video platforms, allows for potential cost savings, in addition to ease and comfort as patients can engage in telemedicine-based resources in the comfort of their homes. Furthermore, survivors prefer to seek information online making telemedicine approaches for prostate cancer survivorship care an ideal combination. A majority of the telemedicine-based interventions used the web, followed by telephone, mobile, and video platforms. In limited studies, telemedicine delivery of survivorship care has equal efficacy to traditional care delivery. In addition, although older patients did not use the Internet regularly, they were willing to adapt to Internet usage if it had the potential to increase their quality of life. Telemedicine delivery of prostate cancer survivorship care is acceptable, feasible, cost-effective, and potentially preferred by prostate cancer survivors. Additionally, it emphasizes knowledge, self-management and self-monitoring serving to increase self-efficacy. This specialized care allows for greater access and reaches a wider catchment area compared to traditional clinic visits. This is especially important as the number of prostate cancer survivors increases and healthcare systems incorporate alternatives to traditional in-person care.

The use of multiple languages in a technology-based intervention study: A discussion paper

BACKGROUND AND OBJECTIVES

With an increasing number of racial/ethnic minorities in the U.S., nursing research frequently involves the use of multiple languages, especially to promote the understanding of educational materials related to nursing care. Furthermore, with a recent emphasis on innovation in health-related research, the use of technology is prominent in nursing research. However, practical issues in the use of multiple languages, especially in technology-based intervention studies, have rarely been reported and/or discussed in nursing literature. The purpose of this paper is to identify practical issues in conducting a technology-based intervention study using multiple languages among Asian American breast cancer survivors.

METHODS

In a large-scale technology-based breast cancer intervention study, research team members wrote memos on issues in translation process and plausible reasons for the issues. Then, the memos and written records were analyzed using a content analysis. By using individual words as the unit of analysis, line-by-line coding was done, and idea categories representing practical issues were extracted from the codes.

RESULTS

Six themes representing the practical issues were extracted. Issues were found in recruiting and retaining bilingual research team members; maintaining consistency in translation process; keeping cultural and conceptual equivalence; repeating IRB protocol modifications; finding and using existing translated versions; and arranging technological aspects related to electronic multiple-language versions.

CONCLUSION

The use of multiple languages in a technology-based intervention study is feasible. However, it is necessary to effectively manage unforeseen challenges through various strategies.

A culturally tailored Internet cancer support group for Asian American breast cancer survivors: A randomized controlled pilot intervention study

Introduction The necessity of culturally competent Internet Cancer Support Groups (ICSGs) for ethnic minorities has recently been highlighted in order to increase its attractiveness and usage. The purpose of this study was to determine the preliminary efficacy of a culturally tailored registered-nurse-moderated ICSG for Asian American breast cancer survivors in enhancing the women's breast cancer survivorship experience. Methods The study included two phases: (a) a usability test and an expert review; and (b) a randomized controlled pilot intervention study. The usability test was conducted among five Asian American breast cancer survivors using a one-month online forum, and the expert review was conducted among five experts using the Cognitive Walkthrough method. The randomized controlled pilot intervention study (a pre-test and post-test design) was conducted among 65 Asian American breast cancer survivors. The data were analysed using content analysis and descriptive and inferential statistics including the repeated ANOVA. Results All users and experts positively evaluated the program and provided their suggestions for the display, educational contents, and user-friendly structure. There were significant positive changes in the support care needs and physical and psychological symptoms ( p < 0.05) of the control group. There were significant negative changes in the uncertainty level of the intervention group ( p < 0.10). Controlling for background and disease factors, the intervention group showed significantly greater improvements than the control group in physical and psychological symptoms and quality of life ( p < 0.10). Discussion The findings supported the positive effects of ICSGs on support care needs, psychological and physical symptoms, and quality of life.

Practical Issues in Developing a Culturally Tailored Physical Activity Promotion Program for Chinese and Korean American Midlife Women: A Pilot Study

Background

With advances in computer technologies, Web-based interventions are widely accepted and welcomed by health care providers and researchers. Although the benefits of Web-based interventions on physical activity promotion have been documented, the programs have rarely targeted Asian Americans, including Asian American midlife women. Subsequently, culturally competent Web-based physical activity programs for Asian Americans may be necessary.

Objective

The purpose of our study was to explore practical issues in developing and implementing a culturally competent Web-based physical activity promotion program for 2 groups of Asian American women—Chinese American and Korean American midlife women—and to provide implications for future research.

Methods

While conducting the study, the research team members wrote individual memos on issues and their inferences on plausible reasons for the issues. The team had group discussions each week and kept the minutes of the discussions. Then, the memos and minutes were analyzed using a content analysis method.

Results

We identified practical issues in 4 major idea categories: (1) bilingual translators’ language orientations, (2) cultural sensitivity requirement, (3) low response rate, interest, and retention, and (4) issues in implementation logistics.

Conclusions

Based on the issues, we make several suggestions for the use of bilingual translators, motivational strategies, and implementation logistics.

Systematic review of the association between dietary acid load, alkaline water and cancer

OBJECTIVES

To evaluate the evidence for a causal relationship between dietary acid/alkaline and alkaline water for the aetiology and treatment of cancer.

DESIGN

A systematic review was conducted on published and grey literature separately for randomised intervention and observational studies with either varying acid-base dietary intakes and/or alkaline water with any cancer outcome or for cancer treatment.

OUTCOME MEASURES

Incidence of cancer and outcomes of cancer treatment.

RESULTS

8278 citations were identified, and 252 abstracts were reviewed; 1 study met the inclusion criteria and was included in this systematic review. No randomised trials were located. No studies were located that examined dietary acid or alkaline or alkaline water for cancer treatment. The included study was a cohort study with a low risk of bias. This study revealed no association between the diet acid load with bladder cancer (OR=1.15: 95% CI 0.86 to 1.55, p=0.36). No association was found even among long-term smokers (OR=1.72: 95% CI 0.96 to 3.10, p=0.08).

CONCLUSIONS

Despite the promotion of the alkaline diet and alkaline water by the media and salespeople, there is almost no actual research to either support or disprove these ideas. This systematic review of the literature revealed a lack of evidence for or against diet acid load and/or alkaline water for the initiation or treatment of cancer. Promotion of alkaline diet and alkaline water to the public for cancer prevention or treatment is not justified.

Transrectal Ultrasound Guided Biopsy of the Prostate: Is the Information Accessible, Usable, Reliable and Readable?

BACKGROUND/AIMS

To evaluate the accessibility, usability, reliability and readability of Internet information regarding transrectal ultrasound (TRUS) guided biopsy of the prostate.

MATERIALS AND METHODS

The terms "prostate biopsy", "TRUS biopsy" and "transrectal ultrasound guided biopsy of the prostate" were separately entered into the each of the top 5 most accessed Internet search engines. Websites were evaluated for accessibility, usability and reliability using the LIDA tool - a validated tool for the assessment of health related websites. Website readability was assessed using the Flesch Reading Ease Score and the Flesch Kincaid Grade Level.

RESULTS

Following the application of exclusion criteria, 82 unique websites were analyzed. There was a significant difference in scores depending on authorship categories (p ≤ 0.001), with health related charity websites scoring highest (mean 122.29 ± 13.98) and non-academic affiliated institution websites scoring lowest (mean 87 ± 19.76). The presence of advertisements on a website was associated with a lower mean overall LIDA tool score (p = 0.024). Only a single website adhered to the National Institutes for Health recommendations on readability.

CONCLUSIONS

This study demonstrates variability in the quality of information available to Internet users regarding TRUS biopsies. Collaboration of website design and clinical acumen are necessary to develop appropriate websites for patient benefit.

Readability and quality assessment of websites related to microtia and aural atresia

OBJECTIVE

Many parents and children utilize the Internet for health-related information, but the quality of these websites can vary. The objective of this study was to assess the quality and readability of microtia and aural atresia related websites.

METHODS

The search engine Google was queried with the terms 'microtia' and 'aural atresia.' The first 30 results were evaluated, and those websites containing original information written in English were reviewed. Quality of content was assessed with the DISCERN instrument, and readability was assessed with the Flesch-Kincaid Reading Grade Level (FKGL) and the Flesch Reading Ease Score (FRES) tests. Each website was also reviewed for ownership and the date of last update.

RESULTS

Sixteen microtia and 14 aural atresia websites were included for full review. The mean DISCERN score for microtia websites was 54.4 (SD=8.3), and for aural atresia websites it was 47.6 (SD=10.7), which indicates 'good' and 'fair' quality of content, respectively. Readability assessments showed an average reading level requiring a grade 10 education on FKGL, and only one microtia (6.3%) and one aural atresia (7.1%) websites were deemed to be at 'reasonable' reading level on FRES.

CONCLUSION

High-quality websites that are considered easily comprehensible to the general public were lacking. Since parents and children may use websites when making treatment decisions, physicians should be aware of the quality of health information pertaining to their area of expertise available on the Internet.

Educational benefits of Internet and computer-based programmes for prostate cancer patients: a systematic review

OBJECTIVE

This study aims to review systematically the available literature on Internet and computer-based patient education programmes, assess the quality of these studies and analyze the benefit of these programmes for prostate cancer patients.

METHODS

Complete databases were searched. Studies were included if they concerned patient education of prostate cancer patients, were qualitative or quantitative and examined Internet or interactive CD-ROM use.

RESULTS

Eighteen studies met the inclusion criteria. The majority of the studies reported a significant increase in the knowledge of the disease, satisfaction with treatment options and support for men. The benefit of the programmes was that the patients felt more empowered and obtained a heightened sense of control over their disease.

CONCLUSION

The Internet or computer-based programmes had a positive impact on prostate cancer patient education. Most papers reported that the programmes were beneficial, but few presented data from studies with rigorous research methodologies to support these claims.

PRACTICE IMPLICATIONS

Internet and computer-based programmes can be useful tools in prostate cancer patient education. In order to improve the benefits of the programmes, more Internet and computer-based programmes need to be developed and studied.

Localized prostate cancer treatment decision-making information online: improving its effectiveness and dissemination for nonprofit and government-supported organizations

The current study reports findings from evaluation research conducted to identify how online prostate cancer treatment decision-making information can be both improved and more effectively disseminated to those who need it most. A multi-method, multi-target approach was used and guided by McGuire's Communication Matrix Model. Focus groups (n = 31) with prostate cancer patients and their family members, and in-depth interviews with physicians (n = 8), helped inform a web survey (n = 89). Results indicated that physicians remain a key information source for medical advice and the Internet is a primary channel used to help make informed prostate cancer treatment decisions. Participants reported a need for more accessible information related to treatment options and treatment side effects. Additionally, physicians indicated that the best way for agencies to reach them with new information to deliver to patients is by contacting them directly and meeting with them one-on-one. Advice for organizations to improve their current prostate cancer web offerings and further ways to improve information dissemination are discussed.

Website visitors asking questions online to lung cancer specialists: what do they want to know?

BACKGROUND

In 2003 the Dutch Lung Cancer Information Centre (Longkanker Informatie Centrum) launched a website containing information on lung cancer accessible to anyone.

OBJECTIVE

Our study aim was to inventorize the information needs of the visitors of this website by analyzing the questions they asked the lung cancer specialists in the websites interactive section "Ask the Physician".

METHODS

The first 2000 questions posted up until May 2006 have been classified by visitors' wish, type of required information, identity, gender, and phase during treatment course.

RESULTS

Our results show that 1893 (1158/1893, 61%) of the questions were asked by a loved one/caregiver and (239/1893 13%) by patients. 1 out of 3 questions was asked by a daughter/grand-daughter. Most questions concerned specific information on lung cancer and lung cancer course (817/1893, 43%). The most inquired specific information topics were therapy side effects, diagnostics, general information on lung cancer, and regular therapy. Furthermore, questioners wanted to verify their own doctor's information (122/1893, 6%), a diagnosis (267/1893, 14%), and a prognosis (204/1893, 11%).

CONCLUSIONS

Lung cancer patients and their caregivers asked the most questions in the interactive website section. The most frequently requested information was more detailed information. These include specific information on lung cancer (regular therapy, diagnostics, and disease symptoms), verification of what the doctor has said, diagnosis, and prognosis. Most of the requested information could have been obtained from treating specialists, indicating that current information supply to lung cancer patients and their caregivers may not be matching their needs sufficiently. The further implementation of an online dialogue with lung cancer specialists might be a solution.

The utilization of oncology web-based resources in Spanish-speaking Internet users

OBJECTIVES

There currently are few web-based resources written in Spanish providing oncology-specific information. This study examines utilization of Spanish-language oncology web-based resources and evaluates oncology-related Internet browsing practices of Spanish-speaking patients.

METHODS

OncoLink (http://www.oncolink.org) is the oldest and among the largest Internet-based cancer information resources. In September 2005, OncoLink pioneered OncoLink en español (OEE) (http://es.oncolink.org), a Spanish translation of OncoLink. Internet utilization data on these sites for 2006 to 2007 were compared.

RESULTS

Visits to OncoLink rose from 4,440,843 in 2006 to 5,125,952 in 2007. OEE had 204,578 unique visitors and 240,442 visits in 2006, and 351,228 visitors and 412,153 visits in 2007. Although there was no time predilection for viewing OncoLink, less relative browsing on OEE was conducted during weekends and early morning hours. Although OncoLink readers searched for information on the most common cancers in the United States, OEE readers most often search for gastric, vaginal, osteosarcoma, leukemia, penile, cervical, and testicular malignancies. Average visit duration on OEE was shorter, and fewer readers surveyed OEE more than 15 minutes (4.5% vs. 14.9%, P < 0.001).

CONCLUSIONS

Spanish-speaking users of web-based oncology resources are increasingly using the Internet to supplement their cancer knowledge. Limited available resources written in Spanish contribute to disparities in information access and disease outcomes. Spanish-speaking oncology readers differ from English-speaking readers in day and time of Internet browsing, visit duration, Internet search patterns, and types of cancers searched. By acknowledging these differences, content of web-based oncology resources can be developed to best target the needs of Spanish-speaking viewers.

Readability of websites containing information about prostate cancer treatment options

PURPOSE

Approximately 90 million American adults have literacy skills that test below a high school reading level. Websites written above this level can pose a challenge for those seeking online information about prostate cancer treatment options. In this study we determine the readability of selected websites using a systematic search process and validated readability formulas.

MATERIALS AND METHODS

We identified the 3 most popular keywords from 513 terms related to prostate cancer treatment options. We then systematically collected 270 websites from the top 3 search engines, and excluded from study those that were nonEnglish, not primarily text, irrelevant and/or duplicated. We used the Flesch-Kincaid grade level and Flesch Reading Ease to determine scores for each site.

RESULTS

A total of 62 unique websites were analyzed. Median Flesch-Kincaid grade level was 12.0 (range 8.0 to 12.0) and median Flesch Reading Ease score was 38.1 (range 0.0 to 65.5). Only 3 sites (4.8%) were written below a high school reading level (less than 9.0).

CONCLUSIONS

Few websites with discussions on prostate cancer treatment options are written below a high school reading level. This is problematic for a third of Americans who seek to further educate themselves using online resources. Clinicians can use this information to guide their patients to appropriate websites.

Communicating health decisions: an analysis of messages posted to online prostate cancer forums

BACKGROUND

Experiential websites such as message forums and blogs allow Prostate Cancer (PCa) patients to communicate their health decisions to peers. The issues surrounding this form of indirect involvement in public health are little understood.

OBJECTIVE

This paper explores the types of decision-making processes that people are exposed to on PCa online message boards. The kinds of treatment choices patients are making and the reports of their decision-making processes to peers through an online environment are examined in the context of the Heuristic Systematic Model.

METHOD

Messages about treatment decision making were collected from four PCa websites. In total, 137 messages were selected from blogs and online forums and their decision-making processes coded.

RESULTS

Men looking online for information about treatment options for PCa are exposed to a range of decision-making processes. Just under half (49.6%) of the messages reported non-systematic decision processes, with deferral to the doctor and proof of cancer removal being the most common. For systematic processing (36.5%), messages most commonly considered treatment outcomes and side-effects. Processes did not vary between the blogs and online forums.

DISCUSSION AND CONCLUSION

Compared to previous studies far fewer messages reported non-systematic decision processes and only a small number of messages reflected lay beliefs or misbeliefs about PCa treatment. Implications for men and their clinicians of seeking health information online are discussed.

Internet chemotherapy information: impact on patients and health professionals

Background:

Reliable information can improve patients’ knowledge of chemotherapy. As internet chemotherapy information (ICI) is increasingly viewed as a valuable patient education tool, we investigated the impact of ICI on patient care and analysed health professionals’ (HPs’) attitudes towards ICI.

Methods:

The following questionnaires were distributed: (1) self-administered questionnaire randomly given to 261 patients receiving chemotherapy (80% returned); and (2) separate questionnaire given to 58 HPs at the same UK Oncology Centre (83% returned).

Results:

Just over half of the patient respondents accessed the internet regularly. They were younger, with higher incomes and qualifications. Key search topics included chemotherapy modes of action, symptom management and treatment success, and most considered ICI useful. More than half wanted to discuss ICI with HPs but most did not get the opportunity. Although the majority of HP respondents supported the need for patients to retrieve ICI, most questioned the accuracy of ICI and did not routinely recommend its use.

Conclusion:

This study has shown that ICI is generally perceived by patients to be a valuable information resource. Given the potential impact of ICI, the following should be addressed in future studies: (1) inequalities in accessing ICI; (2) maintaining the quality of ICI (with clear guidance on recommended websites); (3) bridging the gap between the perception of ICI by patients and HPs; (4) integration of ICI with traditional consultation models.

Treatment decision-making for localized prostate cancer: what younger men choose and why

BACKGROUND AND OBJECTIVE

The literature lacks knowledge about information preferences and decision-making in young prostate cancer patients. This study provides insight into information sources consulted and factors dictating treatment decision-making in young prostate cancer patients.

METHODS

Subjects were identified from pathology consult service of a National Center of Excellence. Questionnaires were mailed to 986 men, under 50 years of age, diagnosed with Gleason score 6 prostate cancer between 2001 and 2005.

RESULTS

Four hundred ninety-three men responded. The most common primary therapies were surgery 397 (81.4%), radiation 52 (10.7%), and active surveillance (AS) 26 (5.3%). Participants with at least some college education (P = 0.003) or annual income >$100,000 (P = 0.003) were more likely to consult three or more doctors. Amongst all treatments, "doctor's recommendation" was the most influential information source, although relatively less important in the AS group. Internet was the second most frequent information source. Participants with higher education (P = 0.0003) and higher income (P = 0.002) considered sexual function more important while making a treatment choice. Only 2% of the men preferred a passive role in the decision-making. Informed decision-making was preferred more by patients who chose radiation and AS while shared decision-making was preferred more by surgery patients (P < 0.05). The majority (89%) of the respondents did not regret their decision. No difference in satisfaction levels was found between different treatment modalities.

CONCLUSIONS

This study provides insight into information sources consulted, such as the greater internet use, and various factors dictating treatment decision-making in young prostate cancer patients. There was an overall very high satisfaction rate regardless of the therapy chosen.

The questions on the use of internet cancer support groups: instrument development

Recently, with advances in computer technologies, Internet cancer support groups became more popular than ever among people living with cancer. However, there is little information available on cancer patients' use of Internet cancer support groups, which may be partially due to a lack of instruments measuring cancer patients' use of Internet cancer support groups. Indeed, virtually no instrument measuring cancer patients' use of Internet cancer support groups can be identified through searches using multiple databases. In this study, a new instrument measuring the use of Internet cancer support groups was developed, and its psychometric properties were tested among 117 people living with cancer recruited through the Internet using a convenience sampling method. First, the development process of the new instrument, the Questions on the Use of Internet Cancer Support Groups, is described. Then, the pilot study on psychometric properties of the instrument is presented. Reliability was evaluated using internal consistency reliability testing, split-half reliability testing, and item analysis. Validity was assessed by using criterion validity, convergent validity, and face validity. The findings of the pilot study supported the reliability and validity of this new instrument. Based on the findings, some implications for future research are proposed.

The Use of Internet Cancer Support Groups by Asian Americans and White Americans Living With Cancer

Purpose: To explore the use of Internet cancer support groups (UICSG) by Asians and Whites living with cancer and determine the factors influencing their UICSG. Design and Method: A cross-sectional Internet study among 30 Asians and 30 Whites. The instruments included (a) questions on sociodemographic and cultural factors, and disease status, (b) the Support Care Needs Survey-34 Short Form, (c) the 2003 Health Information National Trends Survey subscale on Internet usage, and (d) the UICSG Questionnaire. The data were analyzed using the Wilcoxon rank-sum test and nonparametric multiple regression analyses. Results: There was a significant ethnic difference in the UICSG, but there were no ethnic differences in general Internet use or needs for help. Across the ethnic groups, the significant factors influencing the UICSG included “self-reported ethnic identity,” “born in the United States,” and “general Internet use.” Conclusion: Nurses should consider the cultural factors that influence the UICSG.

Patterns of computer and Internet usage among urology patients in two rural Northern Ontario communities

INTRODUCTION

We wanted to determine if the Internet can be used as a potential health promotion tool among urology patients in Northern Ontario. We identified patients' computer and Internet access and use patterns in Kirkland Lake and Kapuskasing, Ontario.

MATERIALS AND METHODS

This study was reviewed and approved by the ethics boards of the Kapuskasing and Kirkland Lake hospitals and Brock University. Data were collected by hand-written questionnaires in English and French. We performed a descriptive analysis of the data obtained.

RESULTS

Out of the 137 questionnaires distributed and collected, we achieved a 95% response rate (7 questionnaires were incomplete). There were 67 men (52 %) and 63 women (48%) ranging in age from 24 to 84 (mean 56). Languages spoken were English (57%), French (38%) and other (5%). We divided the responses into 3 groups: non-Internet users, those with a computer but no Internet access and Internet users. Internet and non-Internet users were studied. Our results indicated that younger respondents, those with higher education and higher paying jobs, used the computer and Internet more often. The main reason behind their Internet was to seek health information for themselves, family and friends.

CONCLUSION

About half of the respondents (55%) used the Internet to access health information. Patients' reactions toward online communication with their family physician were mixed. One limitation of this study is the small sample size, which inhibits making far-reaching conclusions. Our results demonstrate that individual empowerment, access to health information and access to services via emerging technologies are important issues for urology patients in rural Northern Ontario.

Access to information sources and treatment considerations among men with local stage prostate cancer

OBJECTIVES

To determine the role of information sources in the treatment decision-making process of men diagnosed with local stage prostate cancer. Diagnosed men have access to a large number of information sources about therapy, including print and broadcast media, the Internet, books, and friends with the disease.

METHODS

Prospective survey of men with local stage prostate cancer in 3 geographically separate regions was carried out. Most men were surveyed after diagnosis but before starting therapy.

RESULTS

On average, men with local prostate cancer consulted nearly 5 separate sources of information before treatment. The most common source of information was the patient's physician (97%), followed by lay-literature (pamphlets, videos) (76%), other health professionals (71%), friends with prostate cancer (67%), and the Internet (58%). Most men rated the sources they consulted as helpful. Consulting the Internet was associated with considering more treatment options. Several information sources were significantly associated with considering particular treatments, but the magnitude of association was small in relation to patient age, comorbidity, and Gleason score. More than 70% of men stated that they were considering or planning only one type of therapy.

CONCLUSIONS

Men with local stage prostate cancer consult a wide range of information sources. Nonphysician information sources appear to influence their treatment considerations, but to a smaller degree than clinical factors.

A systematic review of patient acceptance of consumer health information technology

A systematic literature review was performed to identify variables promoting consumer health information technology (CHIT) acceptance among patients. The electronic bibliographic databases Web of Science, Business Source Elite, CINAHL, Communication and Mass Media Complete, MEDLINE, PsycArticles, and PsycInfo were searched. A cited reference search of articles meeting the inclusion criteria was also conducted to reduce misses. Fifty-two articles met the selection criteria. Among them, 94 different variables were tested for associations with acceptance. Most of those tested (71%) were patient factors, including sociodemographic characteristics, health- and treatment-related variables, and prior experience or exposure to computer/health technology. Only ten variables were related to human-technology interaction; 16 were organizational factors; and one was related to the environment. In total, 62 (66%) were found to predict acceptance in at least one study. Existing literature focused largely on patient-related factors. No studies examined the impact of social and task factors on acceptance, and few tested the effects of organizational or environmental factors on acceptance. Future research guided by technology acceptance theories should fill those gaps to improve our understanding of patient CHIT acceptance, which in turn could lead to better CHIT design and implementation.

Addressing the information needs of patients with prostate cancer: A literature review

Psychosocial support is a cornerstone in the holistic care of cancer patients. The provision of information is a key tool in the psychosocial management of the cancer patient, and it is important that the therapy radiographer is cognizant of the patient's need for information.

This article reviews the importance of information to the psychosocial well-being of cancer patients in general, with specific emphasis on patients with prostate cancer. The information services at a large Canadian cancer facility are also reviewed to gain some insight into how the needs of patients with prostate cancer are addressed at the author's workplace.

Most patients with prostate cancer have an expressed need for considerable amounts of information at various stages of their cancer journey. The provision of information has a range of benefits to the prostate patient such as helping the patient deal with their diagnosis, assisting with the decision-making process and reducing anxiety.

Interpersonal sources of information such as face-to-face communication with the oncologist or radiation therapist are preferred by many patients, including patients with prostate cancer. Other sources that include the internet and written hospital material are also used with varying degrees of effectiveness to deliver information.

The provision of quality information in a timely and effective manner cannot be taken for granted. Access to appropriate information resources can be impeded because of poorly designed information material, inadequate communication, ineffective signposting, resource constraints and lack of knowledge/comprehension on the part of frontline health-care workers dealing with the patient. Radiation therapists are encouraged to be advocates for their patients’ information needs and to be involved in initiatives that will improve the quality, dissemination and efficacy of information.

The Use of Internet Cancer Support Groups by Ethnic Minorities

Recent studies have indicated that Internet Cancer Support Groups (ICSGs) tend to serve highly educated, high-income Whites at an early stage of cancer. Why do very few ethnic minority cancer patients, especially ethnic minority women, participate in ICSGs? In this article, the possible answers to this question are explored through a literature review from a feminist perspective. The potential reasons identified through the review include (a) gender and ethnic differences in attitudes toward ICSGs, (b) gender and ethnic differences in need for help, and (c) gender- and ethnic-specific contexts. Based on the discussion, implications for future research are proposed.

Filling a void: thyroid cancer surgery information on the internet

BACKGROUND

Thyroid cancer incidence is increasing, making it an important public health issue. Many patients use the Internet for health-related decisions. Our purposes were to measure the quality of thyroid cancer surgery information on the Internet, and to identify quality predictors.

METHODS

The 50 most popular thyroid cancer websites from Google, Yahoo, and MSN were identified. A novel 55-point instrument based on current clinical practice guidelines was designed and used by a Delphi panel of 5 "blinded" endocrine surgeons to assess website information. Each website was independently evaluated by two surgeons. Quality was related to website demographic data using the Student's t-test, chi-square, and ANOVA analyses.

RESULTS

Inter-rater reliability for quality scores was excellent (kappa = 0.81). Mean (% of overall quality) score was 21 (38%), and mean score for surgical content was low at 3.5 (29%). Only 50% of sites discussed indications for surgery; 8% length of surgery/anesthesia; 42% the role of lymphadenectomy; 44% recurrent laryngeal nerve injury/hoarseness and 42% hypoparathyroidism as potential complications; 16% recovery; and 20% recommendations for choosing a thyroid surgeon. Only 38% were updated within 2 years. On univariate analysis, no significant associations were found between surgical quality score and website country of origin, currency, sponsorship, authorship, oversight, or references.

CONCLUSIONS

Thyroid cancer surgery websites on the Internet are incomplete and outdated. No predictors of quality were identified. Significant improvement is needed in regulating information about thyroid cancer surgery on the Internet, and surgeons may contribute to this effort.

Patients' Attitudes Toward Internet Cancer Support Groups

PURPOSE/OBJECTIVES

To explore patients' attitudes toward Internet cancer support groups (ICSGs) through an online forum.

RESEARCH APPROACH

Qualitative study using a feminist perspective.

SETTING

Internet and real settings.

PARTICIPANTS

16 patients with cancer.

METHODOLOGIC APPROACH

An online forum was held for one month with six discussion topics. The data were analyzed using thematic analysis.

MAIN RESEARCH VARIABLES

Attitudes toward ICSGs.

FINDINGS

Through the data-analysis process, four themes were found related to patients' attitudes toward ICSGs. First, the participants universalized patients' needs for and attitudes toward ICSGs. Second, most of the participants wanted to use ICSGs for emotional support, information, and interactions. Third, many of the participants used ICSGs because they could reach out to other patients with cancer without traveling and without interrupting their busy schedules. Finally, many participants were concerned about the security of interactions on ICSGs, so they wanted ICSGs that could ensure privacy and safeguard the anonymity and confidentiality of what they shared online.

CONCLUSIONS

Patients view ICSGs positively. Additional studies should examine gender-specific and multilanguage ICSGs by recruiting more ethnic minority patients.

INTERPRETATION

Despite concerns about the security of Internet interactions, ICSGs would be an excellent source of social support that is acceptable to patients with cancer.

The Internet as an Emerging Patient Education Tool Among African American Men With Prostate Cancer: An Exploratory Study

The lives of African American men with prostate cancer are greatly influenced by the information available to them, some of which is accessed on the Internet. Research indicates that the Internet can enhance consumer health knowledge but has not reached socioeconomic groups at highest risk for health disparities, such as African American men with prostate cancer. In this study, focus groups were used to explore the perceptions and uses of the Internet as a patient education tool among 39 African American men aged 39 years and older with diverse socioeconomic backgrounds. Nineteen (49%) participants reported using the Internet, 15 (38%) reported no use but indicated it was used on their behalf, and 5 (13%) reported no use and no use on their behalf. The findings revealed varying degrees of Internet use for information and social support. Prostate cancer diagnosis, poor patient—doctor communications, and accessibility influenced Internet use. Accessibility related more to lack of ease and familiarity with Internet use than lack of computer access. With training and awareness, the Internet has potential as a patient education tool among African American men with prostate cancer.

The Internet and prostate cancer patients: searching for and finding information

OBJECTIVE

To define the characteristics of prostate cancer patients who use the Internet.

MATERIAL AND METHODS

In October 2002, 511 prostate cancer patients from Stockholm-Gotland County completed a postal questionnaire consisting of 146 questions regarding use of the Internet, demographic factors, level of information about the disease and its treatment, quality of life and trade-off possibilities.

RESULTS

The response rate was 86.5% (n=511) and the mean age of the respondents was 71 years. A total of 210 men (41.1%) had access to the Internet. Eighty-two men (16.4%) had looked for information on prostate cancer, either by themselves or with the aid of others. Among men aged 50-60 years, 39% were Internet users, compared to 8% among men aged 75-80 years; the figures for university graduates versus those who had only attended elementary school were 33% and 3%, respectively. Fifty of the 82 men (61%) who searched for information regarded themselves as being satisfactorily informed by online information.

CONCLUSIONS

Of the men in this cohort, 16% searched the Internet for information regarding their prostate cancer. Young and well-educated men utilized the Internet more frequently than others, but they did not find information more often than older and less well-educated men. It is possible that the Internet promotes social inequality in obtaining healthcare in favor of well-educated, highly paid individuals.

Myelomeningocele Information on the Internet is Accessible and of Variable Quality, and Requires a High Reading Level

PURPOSE

We assessed the accessibility, readability and quality of myelomeningocele information on the Internet.

MATERIALS AND METHODS

We entered the term "spina bifida" into the Google, Yahoo! and Microsoft Network search engines, and stored the first 100 links from each Web site. A total of 164 unique Web sites remained for analysis, of which 159 were classified as relevant. Relevant Web sites were considered to have relevant content if more than 50% of the text was directly relevant to the disease, and to have relevant educational content if more than 50% of the text was aimed at relaying educational information. Readability was assessed using the Flesch-Kincaid Grade Level scale. The quality of the 159 Web sites with relevant content was assessed using American Public Health Association Criteria for Assessing Health Information on the Internet. Six criteria were assessed, namely credibility, content, links, design, interactivity and caveats. Web sites were analyzed by 2 separate medical doctors, with each reviewer blinded to the findings of the other. A weighted kappa statistic was used to calculate interrater reliability.

RESULTS

Of 159 relevant sites 146 (91.8%) had relevant content and 122 (76.7%) had relevant educational content. The average Flesch-Kincaid reading level was 10.9 (range 6 to 12). Quality was assessed on a 3-point scale, with 1 denoting poor quality, 2 fair and 3 good. Average scores were 1.92 for credibility, 1.88 for content, 2.29 for links, 2.53 for design, 1.99 for interactivity and 2.90 for caveats. The weighted kappa statistic for interrater reliability was 0.83.

CONCLUSIONS

Myelomeningocele information on the Internet is relatively accessible, requires a high reading level for comprehension and is of variable quality.

Outdated and incomplete: a review of thyroid cancer on the World Wide Web

OBJECTIVE

To evaluate the most frequently searched thyroid cancer websites for completeness, accuracy, and consumer friendliness.

DESIGN

The 50 most popular thyroid cancer websites were evaluated using a novel instrument developed by a Delphi panel of endocrine experts and based on practice guidelines. Each website received independent scores for disease-specific information and a final quality score. Quality was related to website demographics using the Student t test, chi-square, and ANOVA analyses.

MAIN OUTCOMES

Interrater reliability was excellent (kappa = 0.81). Most websites were not specific to thyroid cancer alone (72%), contained advertisements (72%), lacked references (66%), and were privately sponsored (50%). Only 38% had been updated within 2 years. "Government" and "Non-Profit" websites were the most consumer friendly. Mean quality score of medical content was 38%, with websites receiving the highest score in "Anatomy/Physiology" (55%) and lowest in "Surgery" (29%). Low quality score was attributed to information deficiency rather than inaccuracy. On univariate analysis, no significant associations were found between quality score and country of origin, currency, sponsorship, authorship, administration, advertisements, or references.

CONCLUSIONS

Thyroid cancer websites are out of date and incomplete, lacking important information sought by patients, particularly surgical information. An accurate, comprehensive, easily available, and patient-oriented thyroid cancer Internet resource is needed for patients.

When do older adults turn to the internet for health information? Findings from the Wisconsin Longitudinal Study

BACKGROUND

Understanding how and when patients use nonphysician sources of health information is important to facilitate shared decision making within provider outpatient visits. However, little is known about which older adults seek health information on the internet or when.

OBJECTIVE

To determine how patient characteristics are related to seeking health information online and to the timing of these searches in relation to doctor visits.

PARTICIPANTS

Six thousand two hundred and seventy-nine respondents (aged 63 to 66 years) who completed the 2004 round of phone and mail surveys (70% response) as part of the Wisconsin Longitudinal Study Graduate Sample.

MEASUREMENTS

Self-reported use of the internet to search for health information and timing of use.

RESULTS

One-third of respondents had searched online for information about their own health or health care. Half of these searched for health information unrelated to their last doctor visit, while 1/3 searched after a visit, and 1/6 searched before. Among respondents with internet access at home or work, years of education (odds ratio [OR]=1.09, confidence interval [CI]=1.06 to 1.13) and openness-to-experience (OR=1.26, CI=1.16 to 1.36) were positively associated with searching online for health information irrespective of timing in relation to doctor visits. Compared with those who had never sought health information online, sicker individuals (especially those with cancer, OR=1.51, CI=1.14 to 1.99) were more likely to seek information online after a doctor visit. Attitudinal and personality factors were related to seeking health information online before or unrelated to a visit.

CONCLUSIONS

There are important differences in the timing of online health information searches by psychological and health characteristics among older adults with internet access.

Information from the Internet: attitudes of Australian oncology patients

BACKGROUND

Patients require accurate information about their illness to make informed decisions. Many sources of information exist, although reliability is variable. Our objective was to investigate information seeking behaviour and attitudes toward health-related information from the Internet in a sample of Australian oncology patients.

METHOD

During their outpatient attendance, 109 patients completed a self-administered paper-pen format questionnaire. They were required to have a recent cancer diagnosis (<6 months ago) adequate English and no cognitive impairment.

RESULTS

Seventy-four per cent of questionnaires were returned. The majority of patients (78%) wanted as much information about their cancer diagnosis as possible and 90% reported receiving adequate information from their treating team. Despite this, more than half actively searched for additional information, with 77% using the Internet. Patients were trusting of information obtained from the Internet. More than half of information searchers discussed information obtained in their search with a health professional. The majority of patients did not believe that information searching adversely affected the doctor-patient relationship.

CONCLUSION

Information searching is common in ambulatory Australian oncology patients, with the Internet being a frequently used resource. To ensure patients find reliable and relevant information and to minimize the risk of harm, health professionals involved in treating oncology patients should provide guidance in finding information sources and assistance in interpreting the information obtained.

A novel computer based expert decision making model for prostate cancer disease management

PURPOSE

We propose a strategic, computer based, prostate cancer decision making model based on the analytic hierarchy process. We developed a model that improves physician-patient joint decision making and enhances the treatment selection process by making this critical decision rational and evidence based.

MATERIALS AND METHODS

Two groups (patient and physician-expert) completed a clinical study comparing an initial disease management choice with the highest ranked option generated by the computer model. Participants made pairwise comparisons to derive priorities for the objectives and subobjectives related to the disease management decision. The weighted comparisons were then applied to treatment options to yield prioritized rank lists that reflect the likelihood that a given alternative will achieve the participant treatment goal. Aggregate data were evaluated by inconsistency ratio analysis and sensitivity analysis, which assessed the influence of individual objectives and subobjectives on the final rank list of treatment options.

RESULTS

Inconsistency ratios less than 0.05 were reliably generated, indicating that judgments made within the model were mathematically rational. The aggregate prioritized list of treatment options was tabulated for the patient and physician groups with similar outcomes for the 2 groups. Analysis of the major defining objectives in the treatment selection decision demonstrated the same rank order for the patient and physician groups with cure, survival and quality of life being more important than controlling cancer, preventing major complications of treatment, preventing blood transfusion complications and limiting treatment cost. Analysis of subobjectives, including quality of life and sexual dysfunction, produced similar priority rankings for the patient and physician groups. Concordance between initial treatment choice and the highest weighted model option differed between the groups with the patient group having 59% concordance and the physician group having only 42% concordance.

CONCLUSIONS

This study successfully validated the usefulness of a computer based prostate cancer management decision making model to produce individualized, rational, clinically appropriate disease management decisions without physician bias.

Estimating development cost for a tailored interactive computer program to enhance colorectal cancer screening compliance

The authors used an actual-work estimate method to estimate the cost of developing a tailored interactive computer education program to improve compliance with colorectal cancer screening guidelines in a large multi-specialty group medical practice. Resource use was prospectively collected from time logs, administrative records, and a design and computing subcontract. Sensitivity analysis was performed to examine the uncertainty of the overhead cost rate and other parameters. The cost of developing the system was Dollars 328,866. The development cost was Dollars 52.79 per patient when amortized over a 7-year period with a cohort of 1,000 persons. About 20% of the cost was incurred in defining the theoretic framework and supporting literature, constructing the variables and survey, and conducting focus groups. About 41% of the cost was for developing the messages, algorithms, and constructing program elements, and the remaining cost was to create and test the computer education program. About 69% of the cost was attributable to personnel expenses. Development cost is rarely estimated but is important for feasibility studies and ex-ante economic evaluations of alternative interventions. The findings from this study may aid decision makers in planning, assessing, budgeting, and pricing development of tailored interactive computer-based interventions.

Why do men choose one treatment over another?: a review of patient decision making for localized prostate cancer

Treatment choices for localized prostate cancer appear to vary widely, although it is unclear whether this variation is a result of patient values or other factors. The authors conducted a systematic review of the literature, identifying 70 articles that focused on prostate cancer decision making. Studies suggest that men consider several issues when making treatment decisions. The authors found conflicting evidence regarding the importance that men place on cancer eradication, with considerable variation in how patients interpret evidence regarding treatment efficacy. The number of physicians that men see and the importance of the physician recommendation were found to vary considerably. Although men stated that side effects are important, few patients reported that side effect factors ultimately influenced their treatment choice. To the authors' knowledge, there is little research regarding how patients' personal values shape and influence their decision, or the role of race/ethnicity or socioeconomic status in preferences for treatment. The authors conclude that variations in treatment decisions may be more indicative of differences in the information patients receive rather than truly reflective of underlying patient preferences. Considerable progress is needed in helping patients fully understand how to balance the complex issues surrounding prostate cancer treatment decision making.
