A new study led by MIT economists has revealed that healthcare program “hotspotting”  which identifies and addresses the needs of super-utilizers of health care to improve their health outcomes and lessen their use of healthcare resources has failed to make a difference. The study involving 800 patients has found that the 180-day hospital readmission rate was 62.3 percent for people in the program and 61.7 percent for people not in the program. Researchers emphasize continuous efforts to improve the efficiency of health care to help people in need of extensive treatment.
