OBJECTIVE To identify facilitators and barriers to implementing outcome measures. METHODS An action-research approach within a hospice and nursing home was used. Staff took part in semistructured interviews pre- and post-implementation of the Palliative Care Outcome Scale (POS), completed diaries and participated in monthly meetings. RESULTS Qualitative content analysis identified barriers to implementation including: a top-down decision-making approach; outcome measures perceived as time-consuming to use; limited resources for data analysis; and a lack of knowledge of the importance of outcome measures. Facilitators to successful implementation include: involving all staff in decisions about implementation; and using a measure that can be adapted to organization needs and clinical practice. The benefits of using the measure are rapidly noticeable. CONCLUSIONS Given the need to evaluate services and the role outcome measures can have within clinical governance, this article indicates methods by which measures may be more successfully implemented.
