Many factors contribute to patients not taking medicines as directed. Australian professional research papers often investigate compliance as an adjunct to other research goals. Consumer research looks at the broader range of factors and issues that might contribute to how consumers use their medicines. This research often identifies questions people say they would like to ask their doctors, such as 'What is the medicine for?' and 'What are the likely effects?'. Sometimes patients will forget to ask, are held back by language or social barriers or are reluctant to trouble a doctor. Effective communication with doctors helps consumers to use their medicines appropriately and this improves their satisfaction with treatments and health care providers.
