BACKGROUND: While significant strides have been made in health research, the incorporation of research evidence into healthcare decision-making has been marginal. The purpose of this paper is to provide an overview of how the utility of health services research can be improved through the use of theory. Integrating theory into health services research can improve research methodology and encourage stronger collaboration with decision-makers. DISCUSSION: Recognizing the importance of theory calls for new expectations in the practice of health services research. These include: the formation of interdisciplinary research teams; broadening the training for those who will practice health services research; and supportive organizational conditions that promote collaboration between researchers and decision makers. Further, funding bodies can provide a significant role in guiding and supporting the use of theory in the practice of health services research. SUMMARY: Institutions and researchers should incorporate the use of theory if health services research is to fulfill its potential for improving the delivery of health care.
BACKGROUND: China's economy has been growing rapidly since 1980, which may have affected blood lipid levels. We carried out a study on serum lipid levels and prevalence of lipid abnormalities in Beijing professional populations in 2001-2002 and assessed the changing trends of lipid levels by comparing the results with that of a similar study in 1984-1986. METHODS: The study population included 31,068 government employees, medical and educational workers and scientific research personnel (male/female 6:4). All participants had physical examination and blood chemistry tests. Lipid parameters analyzed included total cholesterol, low- and high-density lipoprotein (LDL and HDL) cholesterol and triglyceride. RESULTS: Total cholesterol, LDL cholesterol and triglyceride concentrations increased significantly as compared with the 1984-1986 study, but the variations of lipid levels with age and sex remained unchanged. Age-adjusted prevalence of dyslipidemia and its distribution in different sexes and age groups were statistically analyzed. Comparing the results with the data of the US in the 1990s, total cholesterol concentration was lower by 16 mg/dl in men and 18 mg/dl in women, whereas LDL cholesterol concentration was lower by 20 mg/dl in men and 15 mg/dl in women. HDL cholesterol was significantly higher than the US in both genders. CONCLUSIONS: The mean levels of total cholesterol (LDL cholesterol ) increased rapidly in the 1980s, stabilized and descended slightly in 1990s. Coronary lipid risk level in Beijing professional populations is significantly lower than in the US.
