1. Telemedicine: Telemedicine is the use of technology to provide remote medical care, such as video consultations, remote monitoring, and virtual visits. The COVID-19 pandemic has accelerated the adoption of telemedicine, with many healthcare providers and entrepreneurs developing new telemedicine platforms and services. For example, Teladoc Health is a leading telemedicine provider that offers virtual visits with doctors and specialists, while Ro is a telemedicine platform that provides online consultations and prescriptions for a range of conditions.

2. Personalized medicine: Personalized medicine involves tailoring medical treatments to the individual patient, based on their genetic makeup, lifestyle, and other factors. Advances in genomics and data analytics are making personalized medicine more feasible and affordable, and there are many opportunities for healthcare providers and entrepreneurs to develop new personalized medicine products and services. For example, 23andMe is a genetic testing company that provides personalized health reports based on a person's DNA, while Veracyte is a diagnostics company that uses genomic analysis to identify cancer and other diseases.

3. Healthtech: Healthtech refers to the use of technology to improve healthcare delivery and outcomes, such as electronic health records, wearables, and health monitoring devices. There are many opportunities for healthcare providers and entrepreneurs to develop new healthtech products and services, such as mobile apps that help patients manage chronic conditions, or AI-powered diagnostic tools that can identify diseases more accurately and quickly. For example, Apple's Health app allows users to track their health and fitness data from multiple sources, while Babylon Health is an AI-powered chatbot that provides medical advice and diagnoses.

4. Value-based care: Value-based care is a model of healthcare delivery that focuses on improving patient outcomes while reducing costs, by rewarding healthcare providers for achieving specific health goals. There are many opportunities for healthcare providers and entrepreneurs to develop new value-based care models, such as bundled payments for specific medical procedures or chronic conditions. For example, the Cleveland Clinic's bundled payment program for joint replacements has reduced costs and improved outcomes for patients.
