Nashville's HCA Healthcare and New Hyde Park's Northwell Health may face financial struggles due to IT problems. Northwell's recent IT investments in EHR, digital health services, and telehealth have led to a 9% increase in operating expenses. Despite this, Northwell reported a 8.9% rise in operating revenue. Meanwhile, HCA Healthcare's future earnings could be impacted by their use of certified electronic health record technology and interoperability requirements.
