A b s t r a c t Objective: Given the slow adoption of medical informatics in Hong Kong and Asia, we sought to understand the contributory barriers and potential incentives associated with information technology implementation. Design and Measurements: A representative sample of 949 doctors (response rate = 77.0%) was asked through a postal survey to rank a(More)
BACKGROUND Although the cost effectiveness of screening mammography in most western developed populations has been accepted, it may not apply to Chinese women, who have a much lower breast cancer incidence. The authors estimated the cost effectiveness of biennial mammography in Hong Kong Chinese women to inform evidence-based screening policies. METHODS(More)
BACKGROUND AND OBJECTIVES We performed a follow-up survey to document changes in the level of computerization among physicians in Hong Kong between 2000 and 2001, specifically examining whether their self-reported intention to computerize various clinical or administrative tasks actually translated into computerization of these tasks 1 year later.(More)

BACKGROUND Projections of future trends in cancer incidence and mortality are important for public health planning. METHODS By using 1976-2010 data in Hong Kong, we fitted Poisson age-period-cohort models and made projections for future breast cancer incidence and mortality to 2025. RESULTS Age-standardised breast cancer incidence (/mortality) is(More)
BACKGROUND With economic development and population aging, ischaemic heart disease (IHD) is becoming a leading cause of mortality with widening inequalities in China. To forewarn the trends in China we projected IHD trends in the most economically developed part of China, i.e., Hong Kong. METHODS Based on sex-specific IHD mortality rates from 1976 to(More)
BACKGROUND Hong Kong population has experienced drastic changes in its economic development in the 1940s. Taking advantage of Hong Kong's unique demographic and socioeconomic history, characterized by massive, punctuated migration waves from Southern China, and recent, rapid transition from a pre-industrialized society to the first ethnic Chinese community(More)
Bourdon conducted the first laboratory experiment on observer-produced motion parallax as a cue to depth. In three experiments, we replicated and extended Bourdon's experiment. In experiment 1, we reproduced his finding: when the two cues, motion parallax and relative height, were combined, accuracy of depth perception was high, and when the two cues were(More)
BACKGROUND AND OBJECTIVES We evaluated factors associated with physicians' perceptions towards the effects of computers on health care and on current levels of computerization in their practice. We also performed a contingent valuation to quantify physicians' perceived benefits from computerization in a hypothetical ambulatory, solo clinic. METHODS We(More)
