Hip fractures decrease older adults' physical activity and quality of life (QoL). However, no current self-efficacy care programs are managed by clinical nurses, and thus no studies have measured their effects on self-care self-efficacy (SCSE). Hence, this quasi-experimental study determined the effectiveness of a self-efficacy care program (SECP) in 104 older adults receiving hip-fracture surgery who were divided into intervention and control groups. The Strategies Used by People to Promote Health and Short Form-36 were administered pre-surgery and at 1 and 3-month intervals post-surgery. The SCSE and QoL of the SECP group were significantly better than the control group at 1- and 3-month follow-ups post-surgery. Both groups' QoL decreased at one-month post-surgery but increased by 3-months post-surgery. The SECP group had higher psychological QoL than the control group post-surgery. This intervention increased the SCSE and QoL of older adults with hip fractures and improved post-operative care.
