Between Doctor Visits,
More Communication Means Better Health
Dr. Simon, Jackie Celmer, NP and the Adult Medicine Specialists staff members are excited to announce an expansion of our services for Medicare patients who qualify with chronic diseases. Adult Medicine Specialists’ patient engagement program will improve the overall health of
our patients through communication and monitoring.
A care manager, working closely with our physicians, will now be assigned to each patient to provide a greater level of communication and to allow
patients to be more involved in their care. These care managers are certified clinicians who call patients regularly to check on their health status
in-between office visits, which can often be months, or even a year, apart. They will also work with each patient and the doctor to develop and update a personalized health care plan, focusing on the patient’s medical history,
lifestyle and personal goals.
Ultimately, Dr. Simon and Jackie hope to help their patients avoid unnecessary ER visits and enjoy better health through this patient engagement program. A care manager’s frequent communication, monitoring and support, along with regular doctor visits, will make a real difference to many people with chronic diseases.
