 This systematic review examined the effectiveness of various interventions designed to increase compliance with breast cancer clinical practice guidelines, CPGs. The authors found that educational interventions were effective at improving compliance with breast cancer screening recommendations, while reminder systems and multifaceted interventions showed some promise but lacked sufficient evidence to draw conclusions. No cost data was collected, so it is unclear how much these interventions would cost if implemented widely.
