A hospital can provide a service guarantee. A hospital is a service organization, and a physician is only one component of that institution. A hospital's brand reputation is determined by how quickly it resolves issues without sacrificing quality or patient satisfaction.
Only a strong "Hospital Operations team" can solve any problem at the moment. To provide a comfortable working environment, the operations management team is responsible for overseeing all operational processes of the hospital, which includes all clinical and non-clinical divisions.
Only the hospital is liable and accountable for the services given; physicians are not. A hospital can use contemporary resources and procedures to improve quality and thereby provide a service guarantee. A physician is just a hospital employee who is compensated for the services he or she provides to patients. Hospitals can provide it, but they cannot guarantee it.
