Patient and staff experiences of quality in Swedish forensic psychiatric care: a repeated cross-sectional survey with yearly sampling at two clinics.

It is important to highlight both what staff and patients perceive as both high and low quality care. With regular measurements and sufficient resources, training, support and leadership, the chances of successful improvement work increase. This knowledge is important in forensic nursing practice, for teaching and for management and decision makers in the constant work of improving forensic psychiatric care.
