Adherence to a medication regimen is fundamental to good health outcomes for people of all ages. However, evidence suggests there is an increase in the number of people failing to comply with their course of medicines and therefore putting themselves at risk at worst, or possibly reducing the effectiveness of the medications they are taking. Antibiotics are the best examples of failure to comply with medicines. Skip of one or more doses during the therapy results in ineffective therapy.
Statistics show that between 30 and 50 per cent of people do not take their medication doses exactly as prescribed by their healthcare professional or fail to finish their medicine course. Australian figures are consistent with these findings, estimating that 40 per cent of Australians have stopped taking prescribed medicine before they were meant to, on at least one occasion.
Medicine adherence for many patients with chronic disease is also extremely poor– at present on average at only about 50 per cent. This ends in disease-related complications, higher levels of hospitalisation, and increased morbidity and mortality.
In addition to maximising the positive impacts of taking medicine properly, it is necessary to maintain medicine adherence as this can also have a major impact on reducing the number of people admitted to hospital.
Optimising the management of long-term conditions through medication adherence has been shown to decrease and delay the incidence of hospitalisation in patients with chronic diseases. It also has been observed that there is a reduce the need for, and spending on, expensive hospital admissions and medical services.
