Nurse-led shared decision-making on complementary therapy use by patients with diabetes: An participatory action research

Abstract

Aims: The aim of this study was to develop, implement and evaluate a nurse-led shared decision-making model of care for discussing the use of complementary and alternative medicine with diabetic patients and to explore to what extent the risk-benefit assessment of using complementary and alternative medicine can provide a framework for facilitating nurse-patient dialogue and strengthening patient involvement in their disease management.

Design: Participatory action research with pre-post intervention.

Methods: A two-run cycle of action and spirals from participatory action research was undertaken using a purposive sampling method to involve healthcare professionals and diabetic patients from September 2021 to June 2022. The nurse-led shared decision-making model of care was designed and implemented congruent with participatory action research principles. Quantitative measures were collected about patients' perceived involvement in shared decision-making and their understanding of the risks and benefits of using complementary and alternative medicine. Patients' outcomes of disease control (fasting plasma glucose and HbA1c) were also collected. Data were analysed using IBM SPSS software (version 28). Interviews were summarized using thematic analysis. An EQUATOR Network guideline for participatory action research supported the preparation of this paper.

Results: Comparison of pre-post intervention outcomes showed that patients' scale scores on shared decision-making involvement and understanding of the risk-benefit of using complementary and alternative medicine improved significantly after implementing the model. Fasting plasma glucose improved only slightly after a 3-month follow-up.

Conclusions: The care model strengthens patient involvement in their disease management and makes appropriate decisions about CAM use that should reduce potentially harmful side effects or interactions between CAM and conventional medicine.

Implications for the profession and patient care: The shared decision-making model of care incorporates evidence-based CAM research into practice, facilitates the standardization of CAM management in diabetes, improves care options for patients and educates nurses about CAM use in managing diabetes.
