Practice change in chronic conditions care: an appraisal of theories.

BACKGROUND: Management of chronic conditions can be complex and burdensome for patients and complex and costly for health systems. Outcomes could be improved and costs reduced if proven clinical interventions were better implemented, but the complexity of chronic care services appears to make clinical change particularly challenging. Explicit use of theories may improve the success of clinical change in this area of care provision. Whilst theories to support implementation of practice change are apparent in the broad healthcare arena, the most applicable theories for the complexities of practice change in chronic care have not yet been identified. METHODS: We developed criteria to review the usefulness of change implementation theories for informing chronic care management and applied them to an existing list of theories used more widely in healthcare. RESULTS: Criteria related to the following characteristics of chronic care: breadth of the field; multi-disciplinarity; micro, meso and macro program levels; need for field-specific research on implementation requirements; and need for measurement. Six theories met the criteria to the greatest extent: the Consolidate Framework for Implementation Research; Normalization Process Theory and its extension General Theory of Implementation; two versions of the Promoting Action on Research Implementation in Health Services framework and Sticky Knowledge. None fully met all criteria. Involvement of several care provision organizations and groups, involvement of patients and carers, and policy level change are not well covered by most theories. However, adaptation may be possible to include multiple groups including patients and carers, and separate theories may be needed on policy change. Ways of qualitatively assessing theory constructs are available but quantitative measures are currently partial and under development for all theories. CONCLUSIONS: Theoretical bases are available to structure clinical change research in chronic condition care. Theories will however need to be adapted and supplemented to account for the particular features of care in this field, particularly in relation to involvement of multiple organizations and groups, including patients, and in relation to policy influence. Quantitative measurement of theory constructs may present difficulties.

Smoking and quitting: a qualitative study with community-living psychiatric clients.

This paper reports the findings of a study investigating the smoking behaviours of a community-based psychiatric population. Using a qualitative, grounded theory approach, the four diagnostic categories of schizophrenia, bi-polar affective disorder, depression, and personality disorder were studied (24 interviews in total) in order to identify similarities and differences in smoking behaviours and perceptions of links between illness and cigarette smoking. A number of theoretical constructs emerged from the data, many of which confirm and enhance current understandings of issues, such as the role of cigarettes in managing the symptoms of illness. However, several themes not found in the existing literature also emerged. Smoking was found to play a significant existential role in the lives of participants: alleviating the effects of stigma, promoting positive and negative freedoms, and providing core needs as part of quality of life decisions. Perceptions of the nature and degree of interaction between psychiatric symptoms and the 'need' to smoke were also found to be significant. Variations in smoking between the different diagnostic groups were also found, in particular in the process of smoking itself the nature of the nicotine dependence as predominantly physical or psychological, attitudes towards the quitting process and sense of control, and the degree of significance of existential factors. The research findings suggest that we may be able to add new methods to our current ways of intervening to assist people with a mental illness who want to quit smoking. Differences in perceptions and patterns of use suggest that intervention may be more effective if psychiatric diagnosis is also taken into consideration. Because the paper is descriptive and hypothesis generating, its findings need to be tested using a larger sample.

Systemic barriers to quitting smoking among institutionalised public mental health service populations: a comparison of two Australian sites.

BACKGROUND: This article reports the findings from a comparative study investigating smoking behaviours among institutionalised psychiatric populations from a sociological perspective. METHOD: The study involved participant observation of two separate Australian sites between 1999 and 2002, the second site serving to generalise the findings from the first site. DISCUSSION AND CONCLUSIONS: Systemic barriers to quitting were identified, emanating from the mental health system in general. Cigarettes were identified as the currency by which economic, social and political exchange took place between participants who described an enculturation process that involved complex processes of reinforcement to smoke. Once entered into, escape from the smoking culture of the settings appeared to be extremely difficult for clients and staff.
