Research summary
Medication adherence is defined by the World Health Organisation (WHO) as the extent to which a person’s medication taking behaviour corresponds with agreed recommendations from a healthcare provider. WHO reported only 50% or less of the people worldwide adhere to their long-term medications. Medications don’t work in patients who don’t take them. Medication nonadherence leads to poor health outcomes and increased healthcare cost. Although many factors have been identified, medication nonadherence remains prevalent. Considerable unknowns limit the effectiveness of initiatives to support people’s medication taking.
We aim to investigate the use of a new questionnaire (the intentional nonadherence scale, INAS) to assess people’s views about their medications in Singapore and the United Kingdom (UK). Medication is an unwanted reminder of being unwell, hence people may resist their illness and medications. One recent study has shown that the INAS explained significant variance in medication adherence in people with hypertension, gout, and cancer. The researcher has already conducted its use in people with Type 2 Diabetes Mellitus (T2DM) in Singapore and aims to conduct a parallel study in the UK.
We will test the use of the new questionnaire, INAS among people following up with the Lambeth Diabetes Intermediate Care Team. When they come for their regular appointment, we will explain and invite them to join the study, where they will complete the INAS and a few questionnaires by themselves or together with us. If participants are agreeable and meet the additional inclusion criteria, researcher will contact them in 2-4 weeks and 3-6 months for the follow-up study when they come for their regular appointment, over phone or online.
We will ask for their permission to extract relevant medical records and store their information securely. This study will compare the UK and Singapore findings.
