Patients have the right to influence the care they receive, but their wish to participate in care decision-making is unclear.


This study investigates whether participation in nursing documentation influences patient participation in care decision-making, mastery, self-esteem, empowerment and depressive feelings among adult in-patients with chronic disease.

Materials and Methodology

Adult patients (n=39) with chronic diseases were randomized. The intervention group participated in nursing documentation. Upon departure, patients filled in questionnaires about participation in care decision-making, mastery, self-esteem, empowerment and depressive feelings.


The majority of the patients preferred a collaborative or passive role regarding care decision-making. Lack of knowledge was one reason for non-participation. Having been diagnosed more than five years previously meant stronger empowerment.


It is a challenge for nurses to find strategies to assess patients’ wishes regarding participation in care decision-making. Nurses must support patients’ knowledge of their disease and empowerment.
