Concepts of social epidemiology in health services research.
BACKGROUND
Social epidemiologists aim to identify social characteristics that affect the pattern of disease and health distribution in a society and to understand its mechanisms. Some important concepts of social epidemiology are: social inequalities, social relationships, social capital, and work stress.


CONCLUSIONS
Concepts used in social epidemiology can make a useful contribution to health services research because the underlying social factors do not only influence health but are also related to health care. Social inequality indicators like education or income have an impact on access to health care as well as on utilization and quality of health care. Social relationships influence adherence to medical treatment, help-seeking behavior, utilization of health services, and outcomes. Social capital in health care organizations is an important factor for the delivery of high-quality coordinated care. Job stress is highly prevalent among health care providers and can not only affect their health but also their performance.


CONCLUSIONS
The theoretical considerations behind factors like social inequalities, social relationships, social capital and work stress can enrich health services research because theory helps to specify the research question, to clarify methodological issues, to understand how social factors are related to health care, and to develop and implement interventions.
