Objectives To evaluate the compliance of NHS dental practice websites in Wales, UK, with the 2012 GDC document Principles of ethical advertising, before its introduction (2011) and again after its introduction (2014).Methods All practices in Wales with an NHS contract and dental practice website were identified. The content of the website was evaluated to determine if it complied with the principles outlined in the 2012 GDC document Principles of Ethical Advertising.Results Twenty-five percent of the 446 practices sampled in 2011 had a website, compared to 44% of the 436 practices sampled in 2014. The principles best complied with were; displaying the name, geographic address, and telephone number of the practice (100% for both years). None of the websites compared the qualifications or skills of its practitioners to others, therefore 100% complied with this principle. Displaying team members' professional qualification and the country from which this is obtained was fairly well represented; 92% and 61% respectively in 2014; an improvement from only 50% and 49% respectively in 2011. Principles worst complied with were displaying the GDC's address (3% 2011; 9% 2014) or link to the GDC website (11% 2011; 7% 2014) and details of the practice complaints procedure (1% 2011; 5% 2014). Overall, no practice complied with all of the compulsory principles.Conclusion In both 2011 and 2014 no practice website was compliant with all the principles outlined in the 2012 GDC document Principles of ethical advertising. Reflecting results from previous studies, this study showed that compliance is slowly improving, yet over 4 years after the introduction of the mandatory principles, it remains that no practice website is 100% compliant.

This paper is concerned with modelling variations in the use of health-care services between small geographic areas. A range of potential explanatory variables are identified from a review of previous literature, ranging from social, economic, and demographic factors through access to services, and practitioner characteristics, to new measures of behaviour and lifestyle. Real admissions data for the city of Leeds relating to a variety of services over a three-year period are introduced to calibrate a series of utilisation models. It is argued that the strength of the goodness of fit makes these models potentially useful in the evaluation of resource allocation between service providers. By providing better global models of usage it is possible to examine small-area outliers to highlight areas where revealed demand, or usage, is not reflecting need as much as it should. In particular, this paper demonstrates the importance of lifestyle preferences in modelling the utilisation of health-care services.
