Is e-health progressing faster than e-health researchers?

Formal Internet interventions exist in a broad context of diverse online health resources, which share elements in common like information, advice and peer support. However, most online health resources are not created by healthcare professionals. Internet interventions need to be designed to "compete" in that wider context. The democratization of production and distribution is central to the transformative effect of the Internet on society, yet potentially conflicts with healthcare's need for an evidence base and safe practice. This is a core challenge for healthcare on the Internet.

Estimating average growth trajectories in shape-space using kernel smoothing.

In this paper, we show how a dense surface point distribution model of the human face can be computed and demonstrate the usefulness of the high-dimensional shape-space for expressing the shape changes associated with growth and aging. We show how average growth trajectories for the human face can be computed in the absence of longitudinal data by using kernel smoothing across a population. A training set of three-dimensional surface scans of 199 male and 201 female subjects of between 0 and 50 years of age is used to build the model.

Changes in mental health of UK hospital consultants since the mid-1990s.

We assessed changes in the mental health of UK hospital consultants from five specialties, on the basis of surveys done in 1994 (880 participants) and 2002 (1308 participants). The proportion of consultants with psychiatric morbidity rose from 27% (235) in 1994 to 32% (414) in 2002. The prevalence of emotional exhaustion increased from 32% (284) in 1994 to 41% (526) in 2002. Multivariate analyses showed that increased job stress without a comparable increase in job satisfaction accounted for the decline in mental health, which was especially marked in clinical and surgical oncologists. Action is needed to improve the working lives of consultants.

Survey of doctors' experience of patients using the Internet.

BACKGROUND: There have been many studies showing the variable quality of Internet health information and it has often been assumed that patients will blindly follow this and frequently come to harm. There have also been reports of problems for doctors and health services following patient Internet use, but their frequency has not been quantified. However, there have been no large, rigorous surveys of the perceptions of Internet-aware doctors about the actual benefits and harms to their patients of using the Internet. OBJECTIVE: To describe Internet-literate doctors' experiences of their patients' use of the Internet and resulting benefits and problems. METHODS: Online survey to a group of 800 Web-using doctors (members of a UK medical Internet service provider, Medix) in September and October 2001. RESULTS: Responses were received from 748 (94%) doctors, including 375 general practitioners (50%). Respondents estimated that 1%-2% of their patients used the Internet for health information in the past month with no regional variation. Over two thirds of the doctors considered Internet health information to be usually (20%) or sometimes (48%) reliable; this was higher in those recently qualified. Twice as many reported patients experiencing benefits (85%; 95% confidence interval, 80%-90%) than problems (44%; 95% confidence interval, 37%-50%) from the Internet. Patients gaining actual physical benefits from Internet use were reported by 40% of respondents, while 8% reported physical harm. Patients' overall experiences with the Internet were judged excellent 1%, good 29%, neutral 62%, poor 9%, or bad <1%. Turning to the impact of patient Internet use on the doctors themselves, 13% reported no problems, 38% 1 problem, and 49% 2 or more problems. Conversely, 20% reported no benefits for themselves, 49% 1 benefit, and 21% 2 or more benefits. CONCLUSIONS: These doctors reported patient benefits from Internet use much more often than harms, but there were more problems than benefits for the doctors themselves. Reported estimates of patient Internet usage rates were low. Overall, this survey suggests that patients are deriving considerable benefits from using the Internet and that some of the claimed risks seem to have been exaggerated.
