The Construction Of Risk Estimates In A Cancer Genetics Clinic

Abstract

This research is designed to examine the manner in which technologies of risk assessment are operationalized in a regional (NHS) cancer genetics service. It will involve a study of the various organisational, technical and intellectual processes that surround the act of allocating a 'risk' to an individual, as well as some of the health policy and health care implications that flow from the risk assessment.
The research is designed in the context of an in-depth case study of a cancer genetics service. The focus of the study will be on the professionals who work within the clinic (which operates on 3 separate sites within Wales); the documentation, artefacts and procedures that such professionals use in their determination of risk assessments; and the implications of such assessments for a sample of patients drawn from a variety of risk categories, as well as the implications for the health services more generally.

By providing detailed empirical data on all aspects of risk assessment in a clinical context, it is intended that the results of the study will contribute to current work in those areas of medical sociology and the sociology of science/technology concerned with the new genetics, and be of positive benefit to health professionals and those concerned with the planning of secondary (and to a lesser extent, primary) health services. In the latter contexts, we would hope that our work might contribute to an improvement of risk communication procedures that are used in genetics clinics, and that our data on the resource implications of offering risk assessments to people predisposed to relatively common familial cancers will be of use to service planners.

Summary

Background

Recent work in genetics has made it possible to identify healthy individuals and families who may be predisposed to certain types of cancer - such as breast, ovarian and colorectal cancer. In any population most individuals are likely to be assessed as being at 'low' risk of such predisposition, though some would be assessed as 'medium' or 'high' risk. The determination of a person's risk can profoundly influence a large number of important personal and medical decisions.
Assembling a cancer genetics risk estimate is a complex matter, and various technologies and processes are routinely involved. In all instances the evidence gathered in the clinic has to be expertly interpreted by clinicians, laboratory scientists, and nurse-counsellors. Yet, exactly how such professionals arrive at a risk assessment in any one instance, and what kinds of consequences flow from their judgements are issues that are currently under-researched. It is to the examination of such processes that this project is directed.

Research Design

The project is centred on a multi-site regional cancer genetics service. The nodal points for the study will consist of individual cases of risk assessment. Following approval from appropriate ethics committees, and consent from individual patients, about 65 risk assessments will be followed as they progress through the service. How the risk estimates for each case are arrived at will be studied using a variety of qualitative methods. These will concentrate on capturing what professionals say and do within the context of clinic procedures. Interview, conversational and observational data will be collected in addition to relevant documentary materials.
Because allocation to a risk category has implications for the patients and for the health service as a whole, the researchers will also study the treatment and management decisions that are consequent upon a risk assessment. Interviews will be used to follow up on how patients integrate risk assessments into their everyday affairs.

Policy and Academic Implications

We intend our work to contribute to scholarly enquiry on the construction and management of risk, the deployment of science and technology in human service organizations, risk communication, and issues relating to the allocation of health service resources. Above all, however, we hope to shed light on how innovations in clinical genetics serve to redefine the work of health professionals, the nature of 'the patient', and the nature of disease itself.
