Reflective Practice
Here we have presented two cases of Arterial-venous fistulas. The patients were evaluated promptly and given the appropriate treatment, follow up, and referrals. The patient was offered the most current information and treatment based on the clinical situation. Patient care was coordinated between the department of ophthalmology and ancillary services so that the patient received prompt evaluation and treatment.
![Page 38: SUNY Downstate Medical Center Department of Ophthalmology · SUNY Downstate Medical Center Department of Ophthalmology Grand Rounds Michael Dattilo, M.D., Ph.D. April 24, 2013](https://reader033.vdocuments.site/reader033/viewer/2022060312/5f0af9607e708231d42e3fa1/html5/thumbnails/38.jpg)
Patient Care – The patient was appropriately treated in a timely manner with compassion and with the patient’s best interest in mind
Interviewing and Communication Skills – A thorough ROS and history was obtained from the patient
Professionalism – The patient was treated with kindness and in a respectful, professional manner at all times
Medical Knowledge – The scientific literature was reviewed and was applied to the patient encounters
Systems Based Practice – The ophthalmologists were able to work within the framework of the hospital system to obtain the most appropriate care in a timely manner
Practice Based Learning – The patient was monitored closely and interval changes were noted at each visit, documented, and management decisions tailored to the changing clinical course
