Interventions employing mobile technology for overweight and obesity: an early systematic review of randomized controlled trials.

Obesity is a global epidemic with major healthcare implications and costs. Mobile technologies are potential interventions to promote weight loss. An early systematic review of this rapidly growing area of research was conducted. Electronic databases were searched for articles published between January 1998 and October 2011. Data sources included Medline, Embase and the Cochrane Central Register of Controlled Trials. Ongoing research was searched for using clinical trials databases and registers. Out of 174 articles retrieved, 21 met the inclusion criteria of randomized controlled trials (RCTs) on mobile technology interventions facilitating weight loss in overweight and obese adults with any other comparator. A narrative synthesis was undertaken. Seven articles were included and appraised using the Cochrane risk of bias tool: four presented a low risk of bias and three presented a high risk of bias. There is consistent strong evidence across the included multiple high-quality RCTs that weight loss occurs in the short-term because of mobile technology interventions, with moderate evidence for the medium-term. Recommendations for improving the reporting and quality of future trials are made including reporting weight loss in percent to meet clinical standards, and including features such as long-term follow-up, cost-effectiveness and patient acceptability.

Information in primary health care.

The results of two recently completed studies, one in the Trent Region and the other in the Anglia and Oxford Region, of the information-related behaviour of general medical practitioners (GPs) and of information activities within the general practices illustrating the information seeking behaviour of GPs, their generation of information, and communication within, to and from the practice. GPs stated that there is a need for more information to enable practices to function within the changing NHS environment. The increasing emphasis on evidence-based medicine also creates the need for appropriate information sources. The Trent study resulted in guidelines for best information practice, especially the need for each practice to have an information strategy. The Anglia and Oxford Study examined the role which the library and information services could play in supporting primary health care.

Information in general medical practice: a qualitative approach.

The aims of the study reported here were to describe the information-related behavior of general medical practitioners, to study information communication in general practices, and to establish guidelines for good practice. General practitioners (GPs) were interviewed, and information and communication audits also involving other staff at the practices were undertaken. The main reasons why GPs needed information were for patient care, managing the practice, legal and ethical matters, and teaching trainee GPs. Most practices had problems with internal and external communication and the storage and retrieval of information. The main conclusion is that practices need to have an information strategy that considers human, manual, and computer aspects of information handling.
