Crozer Health’s computer systems are now back up and running as normal and the health system is continuing to provide safe, quality care to patients following a data security incident that disrupted our operations. Work to input paper patient records used by our caregivers while our systems were down into our electronic medical record (EMR) system is ongoing.  We appreciate the resilience shown by our physicians and employees during this disruption and we thank our patients for their patience and continued loyalty to our facilities. Delivering safe, quality care is our most important priority.

How the Program Works

  • To get started, attend our FREE educational seminar – there’s no obligation, but it’s required as the first step in joining our program.
  • If you decide to pursue surgery, we’ll provide you with all the information, prescriptions and requests for specialty clearances so you can proceed with your pre-operative workup.
  • Our Team will help track and monitor your progress, including obtaining authorization from your insurance company and scheduling your surgery.
  • After surgery, your surgeon and case management nurse will follow up with you at one week, one month, three months, six months, one year and yearly thereafter.
  • Your dietitian will follow up with you at two weeks, 6 weeks, and 4 months. Further follow-up is strongly suggested to stay on track.
  • Monthly support group attendance will help keep you motivated and allow you to share your success with others.
