Searching robotic prostatectomy online: what information is available?

Readability, credibility and quality of patient information for hypogonadism and testosterone replacement therapy on the Internet

The incidence of hypogonadism and use of testosterone replacement therapy (TRT) are rising, while data evaluating the complexity and quality of health-care information available to patients on the Internet for hypogonadism or TRT are lacking. This study focuses on characterizing the readability, credibility and quality of patient-centered information for hypogonadism on the Internet. A Google search was performed to identify top-ranked websites offering patient-centered information on hypogonadism and TRT. Readability was quantified by reading grade level using several validated instruments. Credibility and quality were determined by several additional criteria, including authorship, references, health-care information quality certification and breadth of topic discussion. Twenty of 75 total sites identified (27%) met the inclusion and exclusion criteria and were evaluated. The mean reading grade level was 13.1 (interquartile range 11.7-15.1), with all websites demonstrating reading levels significantly above recommended levels. Less than half (45%) of the sites were neither authored nor reviewed by a physician, 60% contained at least one reference and 40% were certified for displaying quality health-care information. Over half (55%) did not comprehensively discuss management of hypogonadism or mention treatment-associated risks. In conclusion, the majority of patient-centered information available on the Internet regarding hypogonadism or TRT is of poor quality and too complex for the average patient to comprehend. These results highlight a critical shortage in easily accessible, high-quality, comprehensible online patient health-care information on hypogonadism and TRT.

Technology diffusion and diagnostic testing for prostate cancer

PURPOSE

While the dissemination of robotic prostatectomy and intensity modulated radiotherapy may fuel the increased use of prostatectomy and radiotherapy, these new technologies may also have spillover effects related to diagnostic testing for prostate cancer. Therefore, we examined the association of regional technology penetration with the receipt of prostate specific antigen testing and prostate biopsy.

MATERIALS AND METHODS

In this retrospective cohort study we included 117,857 men 66 years old or older from the 5% sample of Medicare beneficiaries living in Surveillance, Epidemiology and End Results (SEER) areas from 2003 to 2007. Regional technology penetration was measured as the number of providers performing robotic prostatectomy or intensity modulated radiotherapy per population in a health care market, ie hospital referral region. We assessed the association of technology penetration with the prostate specific antigen testing rate and prostate biopsy using generalized estimating equations.

RESULTS

High technology penetration was associated with an increased rate of prostate specific antigen testing (442 vs 425/1,000 person-years, p<0.01) and a similar rate of prostate biopsy (10.1 vs 9.9/1,000 person-years, p=0.69). The impact of technology penetration on prostate specific antigen testing and prostate biopsy was much less than the effect of age, race and comorbidity, eg the prostate specific antigen testing rate per 1,000 person-years was 485 vs 373 for men with only 1 vs 3+ comorbid conditions (p<0.01).

CONCLUSIONS

Increased technology penetration is associated with a slightly higher rate of prostate specific antigen testing and no change in the prostate biopsy rate. Collectively, our findings temper concerns that adopting new technology accelerates diagnostic testing for prostate cancer.

Evidence-based surgery: barriers, solutions, and the role of evidence synthesis

BACKGROUND

Surgery is a rapidly evolving field, making the rigorous testing of emerging innovations vital. However, most surgical research fails to employ randomized controlled trials (RCTs) and has particularly been based on low-quality study designs. Subsequently, the analysis of data through meta-analysis and evidence synthesis is particularly difficult.

METHODS

Through a systematic review of the literature, this article explores the barriers to achieving a strong evidence base in surgery and offers potential solutions to overcome the barriers.

RESULTS

Many barriers exist to evidence-based surgical research. They include enabling factors, such as funding, time, infrastructure, patient preference, ethical issues, and additionally barriers associated with specific attributes related to researchers, methodologies, or interventions. Novel evidence synthesis techniques in surgery are discussed, including graphics synthesis, treatment networks, and network meta-analyses that help overcome many of the limitations associated with existing techniques. They offer the opportunity to assess gaps and quantitatively present inconsistencies within the existing evidence of RCTs.

CONCLUSIONS

Poorly or inadequately performed RCTs and meta-analyses can give rise to incorrect results and thus fail to inform clinical practice or revise policy. The above barriers can be overcome by providing academic leadership and good organizational support to ensure that adequate personnel, resources, and funding are allocated to the researcher. Training in research methodology and data interpretation can ensure that trials are conducted correctly and evidence is adequately synthesized and disseminated. The ultimate goal of overcoming the barriers to evidence-based surgery includes the improved quality of patient care in addition to enhanced patient outcomes.

Direct-to-consumer Internet promotion of robotic prostatectomy exhibits varying quality of information

Robotic surgery to remove a cancerous prostate has become a popular treatment. Internet marketing of this surgery provides an intriguing case study of direct-to-consumer promotions of medical devices, which are more loosely regulated than pharmaceutical promotions. We investigated whether the claims made in online promotions of robotic prostatectomy were consistent with evidence from comparative effectiveness studies. After performing a search and cross-sectional analysis of websites that mentioned the procedure, we found that many sites claimed benefits that were unsupported by evidence and that 42 percent of the sites failed to mention risks. Most sites were published by hospitals and physicians, which the public may regard as more objective than pages published by manufacturers. Unbalanced information may inappropriately raise patients' expectations. Increasing enforcement and regulation of online promotions may be beyond the capabilities of federal authorities. Thus, the most feasible solution may be for the government and medical societies to promote the production of balanced educational material.

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.

Quality evaluation of the available Internet information regarding pain during orthodontic treatment

OBJECTIVE

To investigate the quality of the data disseminated via the Internet regarding pain experienced by orthodontic patients.

MATERIALS AND METHODS

A systematic online search was performed for 'orthodontic pain' and 'braces pain' separately using five search engines. The first 25 results from each search term-engine combination were pooled for analysis. After excluding advertising sites, discussion groups, video feeds, and links to scientific articles, 25 Web pages were evaluated in terms of accuracy, readability, accessibility, usability, and reliability using recommended research methodology; reference textbook material, the Flesch Reading Ease Score; and the LIDA instrument. Author and information details were also recorded.

RESULTS

Overall, the results indicated a variable quality of the available informational material. Although the readability of the Web sites was generally acceptable, the individual LIDA categories were rated of medium or low quality, with average scores ranging from 16.9% to 86.2%. The orthodontic relevance of the Web sites was not accompanied by the highest assessment results, and vice versa.

CONCLUSIONS

The quality of the orthodontic pain information cited by Web sources appears to be highly variable. Further structural development of health information technology along with public referral to reliable sources by specialists are recommended.

The male sling for post-prostatectomy urinary incontinence: a review of contemporary sling designs and outcomes

OBJECTIVE

To examine the outcomes and adverse events associated with novel male sling designs described in the last decade.

METHODS

A literature review was carried out using Medline, EmBase, Cochrane Registered Trials Database and the Center for Reviews and Dissemination Database.

RESULTS

Three principal slings are described in the literature. The bone-anchored sling has success rates of 40-88%, with some series having a mean follow-up of 36-48 months. It is associated with a mesh infection rate of 2-12%, which usually requires sling explantation. The retrourethral transobturator sling has a success rate of 76-91% among three large case series with follow-ups of 12-27 months. There is a low reported explantation rate. The adjustable retropubic sling has a success rate of 72-79% with follow-ups of 26-45 months. Erosion (3-13%) and infection (3-11%) can lead to explantation.

CONCLUSIONS

Most male slings have a similar reported efficacy. Most case series define success as either dry or improved. True cure rates are lower. Mid- and long-term data are now available that indicate the male sling is a viable option for PPI. The use of male slings in severe UI, radiated patients, and non-radical prostatectomy patients is still unclear. Further study is needed to try and define criteria for the use of male slings, and to directly compare different procedures.
