Impact of customized-consumer medication information on health-related quality of life among patients with type 2 diabetes mellitus

Background: The importance of providing accurate medication information that can be easily comprehended by patients to subsequently best use their medication(s) has been widely reported in the literature. Patient information leaflet (PIL) is a supporting tool aiding patients to make decisions about their treatment plan and improve patient-clinician communication and thus medication adherence. PIL is the written document produced by the pharmaceutical manufacturers and packed with the medicine. The available PILs do not consider cultural and behavioral perspectives of diverse populations residing in a country like Qatar. Consumer medication information (CMI) is written information about prescription drugs developed by organizations or individuals other than a drug's manufacturer that is intended for distribution to consumers at the time of drug dispensing.

Objective: To investigate the impact of customized CMI (C-CMI) on health-related quality of life (HRQoL) among type 2 diabetes mellitus (T2DM) patients in Qatar.

Methods: This was a randomized controlled intervention study, in which the intervention group patients received C-CMI and the control group patients received usual care. HRQoL was measured using the EQ-5D-5L questionnaire and EQ visual analog scale (EQ-VAS) at three intervals [i.e. baseline, after 3 months and 6 months].

Results: The EQ-5D-5L index value for the intervention group exhibited sustained improvement from baseline to the third visit. There was a statistically significant difference between groups in the HRQoL utility value (represented as EQ index) at 6 months (0.939 vs. 0.796; p = 0.019). Similarly, the intervention group compared with the control group had significantly greater EQ-VAS at 6 months (90% vs. 80%; p = 0.003).

Conclusions: The impact of C-CMI on health outcomes of T2DM patients in Qatar reported improvement in HRQoL indicators among the intervention patients. The study built a platform for health policymakers and regulatory agencies to consider the provision of C-CMI in multiple languages.
