In Hong Kong, a pilot project is being undertaken to implement a web-based electronic patient record system to allow integrated, real time patient based information to be shared in clinics, private and public hospitals. Such sharing aims to ensure that complete and accurate healthcare information is available to citizens' multiple points of care through a(More)
BACKGROUND Use of electronic medical records (EMR) has the potential to offer quality and safety benefits, but without the adoption of the technology, the benefits will not be realized. OBJECTIVE This study aimed to identify the factors perceived as relevant by private physicians when considering EMR adoption. METHODS A qualitative pre-implementation(More)
BACKGROUND Randomized trials have shown that optimal adherence to antihypertensive agents could protect against cardiovascular diseases, but whether adherence reduces cardiovascular deaths in community settings has not been explored so fully. This study evaluates the association between antihypertensive adherence and cardiovascular (coronary heart disease(More)
BACKGROUND International guidelines recommending antihypertensive prescriptions for the management of hypertension have been published in the past decade. Beta-blocker use was discouraged by a significant body of evidence and angiotensin-converting enzyme inhibitors (ACEIs) or angiotensin receptor blockers (ARBs) were found more effective among younger(More)
PURPOSE Suboptimal adherence to antihypertensive agents leads to adverse clinical outcomes. This study aims to evaluate the association between first-line antihypertensive drug class and medication adherence in a large Chinese population. METHODS All patients prescribed ≥ one antihypertensive drug in 2001-2003 and 2005 who have paid at least two(More)
PURPOSE Adverse effects of antihypertensive therapy incur substantial cost. We evaluated whether any major classes of antihypertensive drugs were significantly associated with switching as a proxy measure of medication side effects in a large Chinese population in Hong Kong. METHODS From a clinical database, all adult patients newly prescribed an(More)
Multimorbidity has become the norm worldwide as populations age. It remains, however, infrequently researched. This study evaluated factors associated with multimorbidity in a predominantly Chinese hypertensive population. We included all adult patients prescribed their first antihypertensive agents in the entire public sector in Hong Kong from a validated(More)
OBJECTIVES To compare the diagnostic accuracy of emergency department (ED) physicians with the World Health Organization (WHO) case definition in a large community-based SARS (severe acute respiratory syndrome) cohort. METHODS This was a cohort study of all patients from Hong Kong's Amoy Garden complex who presented to an ED SARS screening clinic during a(More)
BACKGROUND Randomized trials have shown that the major antihypertensive drug classes are similarly effective to reduce mortality, but whether these drug class difference exists in clinical practice has been scarcely explored. This study evaluated the association between antihypertensive drug class, all-cause mortality and deaths due to diabetes or renal(More)
OBJECTIVES To assess the association of diagnostic predictors available in the emergency department (ED) with the outcome diagnosis of severe acute respiratory syndrome (SARS). METHODS This retrospective cohort study describes all patients from the Amoy Garden complex who presented to an ED SARS screening clinic during a 2-month outbreak. Clinical and(More)
