The internet serves an increasingly critical role in how older adults manage their personal health. Electronic patient portals, for example, provide a centralized platform for older adults to access lab results, manage prescriptions and appointments, and communicate with providers. This study examined whether neurocognition mediates the effect of older age on electronic patient portal navigation.

Forty-nine younger (18–35 years) and 35 older adults (50–75 years) completed the Test of Online Health Records Navigation (TOHRN), which is an experimenter-controlled website on which participants were asked to log-in, review laboratory results, read provider messages, and schedule an appointment. Participants also completed a neuropsychological battery, self-report questionnaires, and measures of health literacy and functional capacity.

Mediation analyses revealed a significant indirect effect of older age on lower TOHRN accuracy, which was fully mediated by the total cognitive composite.

Findings indicate that neurocognition may help explain some of the variance in age-related difficulties navigating electronic patient health portals. Future studies might examine the possible benefits of both structural (e.g., human factors web design enhancement) and individual (e.g., training and compensation) cognitive supports to improve the navigability of electronic patient health portals for older adults.

This study aimed to evaluate the readability and quality of current online information on Bell's palsy.

A Google search using the terms ‘Bell's palsy’ and ‘facial palsy’ was performed separately. The first three pages of results were analysed. Readability was assessed using Flesch Reading Ease Score, Flesch–Kincaid Grade Level, the Gunning-Fog Index and the Simple Measure of Gobbledygook. Quality was assessed using the Discern tool. Spearman's correlation between quality and readability was calculated.

A total of 31 websites met the inclusion criteria. The mean Flesch Reading Ease Score, Flesch–Kincaid Grade Level, the Gunning Fox Index and the Simple Measure of Gobbledygook scores were 52.45 (95 per cent confidence interval = 47.01–57.86), 10.50 (95 per cent confidence interval = 9.42–11.58), 12.76 (95 per cent confidence interval = 11.68–13.85) and 9.36 (95 per cent confidence interval = 8.52–10.20), respectively. The average Discern score was 44 (95 per cent confidence interval = 40.88–47.12). A negligible correlation was noted between the Discern and Flesch Reading Ease Score (rs = −0.05, p = 0.80).

Online information on Bell's palsy is generally of fair quality but is written above the recommended reading age guidance in the UK.

There is limited understanding amongst patients and parents of paediatric patients regarding adenoidectomy. Most patients access health-related information online. The aim of this study was to assess the suitability of online information on adenoidectomy.

The term ‘adenoid’ was used to search Google, and the first 50 websites identified were screened. For each website, the readability and quality were assessed.

Of the 41 websites that met the inclusion criteria, the mean readability scores corresponded to ‘difficult to read’ and university-level reading categories. For the quality of the websites, the mean score corresponded to ‘fair’ with 39 per cent of the websites containing either ‘poor’ or ‘very poor’ quality data. The ENT UK information is one of the most readable and reliable online resources.

The online information on adenoidectomy is largely set at an inappropriate readability level and of variable quality. Surgeons should consider assisting their patients with online searches regarding adenoidectomy.

To verify the reliability of information, the sources of information used and the user opinions of the free mobile applications (apps) with nutritional information available in Brazil.

Descriptive, cross-sectional study.

We evaluated the content about nutrition of free apps available on the App Store of iPhone 5S with software iOS 8.4.1 and on the Play Store of the Android platform, version 2.3.6. For this, we compared the nutrition information provided by the app with (i) the Brazilian Food Composition Table (TACO), of 2011; (ii) food composition table: support for nutritional decision, of 2002; and (iii) the National Study of Family Expenditure: food composition tables, of 1999. The evaluation included the description and quantity of macro- and micronutrients in foods. In addition, we evaluated the trustworthiness of information about food energy values and analysed the comments and ratings made by users.

Mobile apps related to nutrition.

We assessed sixteen apps for mobile devices. Considering the foods selected (a basic Brazilian food basket for the month of August 2015), the apps presented partially adequate or inadequate information about food composition (macro- and micronutrients). The adequacy of the food energy values ranged from 0 to 57·1 %. Despite this, the apps received positive ratings by users.

The mobile apps about nutrition currently available and evaluated in the present study in Brazil are not useful for nutritional guidance because most of them are not based on reliable sources of information.

YouTube is an internet-based repository of user-generated content. This study aimed to determine whether YouTube represented a valid and reliable patient information resource for the lay person on the topic of rhinosinusitis.

The study included the first 100 YouTube videos found using the search term ‘sinusitis’. Videos were graded on their ability to inform the lay person on the subject of rhinosinusitis.

Forty-five per cent of the videos were deemed to provide some useful information. Fifty-five per cent of the videos contained little or no useful facts, 27 per cent of which contained potentially misleading or even dangerous information. Videos uploaded by medical professionals or those from health information websites contained more useful information than those uploaded by independent users.

YouTube appears to be an unreliable resource for accurate and up to date medical information relating to rhinosinusitis. However, it may provide some useful information if mechanisms existed to direct lay people to verifiable and credible sources.

This study aimed to assess the quality of information available on the World Wide Web for patients undergoing thyroidectomy.

The first 50 web-links generated by internet searches using the five most popular search engines and the key word ‘thyroidectomy’ were evaluated using the Lida website validation instrument (assessing accessibility, usability and reliability) and the Flesch Reading Ease Score.

We evaluated 103 of a possible 250 websites. Mean scores (ranges) were: Lida accessibility, 48/63 (27–59); Lida usability, 36/54 (21–50); Lida reliability, 21/51 (4–38); and Flesch Reading Ease, 43.9 (2.6–77.6).

The quality of internet health information regarding thyroidectomy is variable. High ranking and popularity are not good indicators of website quality. Overall, none of the websites assessed achieved high Lida scores. In order to prevent the dissemination of inaccurate or commercially motivated information, we recommend independent labelling of medical information available on the World Wide Web.

This study determined readability scores for sequential letters written to general practitioners and copied to patients, following ENT consultations at the Royal United Hospital in Bath. Intervention involved educating clinicians in techniques to improve readability.

A total of 295 letters from eight clinicians were assessed in the pre-intervention phase. The mean Flesch reading ease score was 61.8 (standard deviation 8.7) and the mean Flesch–Kincaid reading grade was 9.0 (standard deviation 1.7). Re-audit analysed a further 301 letters. There was no significant change in the readability of the letters post-intervention.

It may not be feasible to present medical information intended for general practitioners in a way that is readable to most of the UK adult population.
