Hospital Administrator: The majority of HealthWize Hospital's income currently comes from three main insurance companies. In order to diversify its sources of income, the hospital will develop its outpatient services to provide clients with the opportunity to visit a nutritionist, a gym, and/or a masseuse on the hospital premises. Critics have protested that, at other hospitals, such plans have not worked because the funds raised through insurance payments far outweigh the money that will be brought in through these additional services. Nevertheless, this initiative will not result in a reduction of the hospital's income. Major service providers, including BeWell Nutrition and Fitness, have committed to moving their main branches to HealthWize Hospital, which will definitely prove to be an attraction for people from neighboring areas, making this a more popular venture than other hospitals'.
