gistalt is an iPhone application developed by Tom Fadial in the category of Education & Reference, specifically focusing on Medicine. This free app aims to help healthcare professionals improve their clinical impression skills and accurately identify patients' acuity level.

The main goal of playing gistalt is to determine whether a patient requires immediate hospitalization or can be safely treated with outpatient follow-up. The app presents users with a stack of patient presentations, including vital signs, laboratory results, and imaging. Users swipe each card left if the patient is not-sick or right if the patient is sick.

One of the highlights of gistalt is its simplicity and fun gameplay. After going through the stack of patient presentations, users can review their responses and see their score. The gistalt score specifically measures the user's ability to detect the most critically-ill patients and institute the necessary treatments.

What sets gistalt apart is its regular addition of new questions without requiring an app update. This ensures that users have a continuous learning experience and stay up-to-date with the latest medical scenarios.

Overall, gistalt is a valuable tool for healthcare professionals looking to enhance their clinical impression skills in a fun and engaging way. Whether you're a medical student, resident, or experienced physician, this app provides an educational and entertaining experience to improve your acuity assessment abilities.
