If multiple practices were collaborating (for example with one practice nurse), they formed one cluster which was used for randomization.
Finally, one of the drawbacks of studies that combine data from multiple practices is the between practice variability [ 19]: it is generally assumed that some variability exists between general practitioners in making a diagnose [ 24].
Multiple HR practices are defined as the presence of two or more substantively different HR practices.
Regional characteristics of runoff and nitrogen losses were simulated by an integrated water system model (HEQM) with multi-objective calibration, and multiple agriculture practices were assessed to find the effective approach for the reduction of diffuse nitrogen losses.
Participation of multiple general practices was required to obtain sufficient numbers of subjects and to enhance generalizability.
Participation in multiple prevention practices was more likely than participating in only one practice (40.7 % and 33.0 %, respectively), with the most commonly reported combination being wearing boots and restricting animal access to the garden (Fig. 3).
Multiple risk practices is an index that identifies respondents who engaged in two or more negative health practices – smoking, binge drinking, physical inactivity, use of pain relievers, and/or consuming less than five servings of fruits and vegetables per day.
The relationship between socio-demographic status and a) a range of health behaviours and b) a combination of multiple risk and multiple health promoting practices were examined.
However, this design is the most suitable and practical given the nature of the intervention; a controlled trial with randomization at the level of the patient would be severely limited by contamination, and a cluster randomized controlled trial would require multiple practices, which is not feasible in the context of limited resources.
Multiple health-promoting practices is an index that identifies respondents who engaged in two or more positive health practices, including physical activity, consulting an alternative health care provider, making a change to improve health in the past 12 months, and consuming more than five servings of fruits and vegetables per day.
