Complaint behaviour among healthcare users: self-reported complaint experience and complaint proneness in adult men.

Roughly 1 in 20 men reported having complained about healthcare. Complaints were more common among men who were younger, living in rural areas, diagnosed with chronic illness and high users of healthcare services. Prior complaint experience may be associated with a higher proclivity for complaining about future healthcare. Findings suggest differences in the way healthcare users respond to care experiences, pointing to the importance of aligning expectations and providing clear information about treatment options.
