My early research studies investigated the problems of poly-pharmacy and high risk medications use among elderly population. This is a major problem to geriatrics population that leads to increase medication adverse events, hospitalizations, and mortality. In one project (Poon 2005), it was found that the prevalence of orthostatic hypotension (OH) increased with the number of causative medications and thiazide diuretics was associated with the highest prevalent of OH. Later my research interest was expanded into investigating the role of self-care and medication adherence on disease state management among different racial/ethnic groups in geriatrics population. In several projects, it was found that African Americans were less likely to carry out self-monitoring of blood pressure and less likely to adhere to antihypertensive medications compared to Caucasians regardless of medication cost (Poon 2008, 2009, 2010). The results of the above studies helped to build the foundation to the recent research projects on clinical interventional studies to improve medication adherence among minority elderly patients with chronic illnesses such as hypertension and diabetes. The patient centered care collaboration model was adopted in carrying out these behavioral modification interventions. The goals of these projects were to improve clinical outcomes in elderly patients with chronic illnesses.
