SYMBIOTIC RELATIONSHIPS OF QUALITY-OF-LIFE, HEALTH-SERVICES RESEARCH AND OTHER HEALTH RESEARCH

Clinical biomedical research, the traditional research orientation of quality of life (QOL) researchers, is chiefly concerned with disease processes and assessing the impact of therapeutic interventions on improving health status and QOL outcomes. This paper suggests, however, that the biomedical paradigm limits utility of QOL research findings in terms of its ability to shape health policy and improve health-related QOL in populations at risk. This paper proposes that health services research (HSR) and other health research paradigms can be used to assess QOL from multiple perspectives. HSR and QOL research can be mutually beneficial. The models for understanding health services utilized in HSR may assist in defining major determinants of QOL and the interaction of QOL with its environment. Conversely, QOL measures may be used to establish the relevance of HSR to people's well-being. The paper first defines the domain of HSR and the domain of quality of life. In order to understand their relationship, we consider what a model or paradigm for each might be, and how they would overlap. Finally, a merging of conceptual frameworks is proposed, linking QOL research to HSR and other health research. Ultimately, expanding the QOL paradigm beyond the biomedical model will promote two objectives. First, it will permit research findings to contribute more fully to shaping national health policy by considering the broader community and the delivery system factors which influence QOL. Second, researchers will be more aware of a broader range of factors affecting patients and will incorporate this in their research.
