In 21st century currently we are facing the most critical health concerns are:
- Heart disease, stroke, cancer, diabetes, and other non communicable diseases (NCDs)
- Antibiotic Resistances.
- Mental Health.
- HIV/ AIDS
In not much more than a generation, we have transitioned from a world in which infectious diseases were the greatest health challenge to one in which multiple chronic illnesses and disability are the biggest threat. The implications for our health systems are massive, but not only are they alarmingly ill equipped to cope; we are facing a frightening lack of evidence on how they need to be adapted. If we don’t address this evidence gap quickly. We cannot hope to create health systems capable of delivering the comprehensive care patients so desperately need. Populations are ageing; between 2015 and 2050, the proportion of people aged over 60 is projected to almost double, reaching around 2.1 billion. As a result, many more people are experiencing several diseases simultaneously ,a phenomenon known as multimorbidity. Despite the scale and urgency of this global problem, we lack reliable data particularly when it comes to younger adults and developing countries. We also know very little about how effective health services are at dealing with multiple chronic conditions in the same person. Most health systems around the world are designed around a single condition or body system, with ever-increasing sub-specialization by health professionals in recent decades.Not only this, but research that guides healthcare often excludes people with multiple chronic conditions, potentially limiting its applicability to an ever-diminishing number of people.The focus of the 21st-century health care system must be the patient. Such a system will ensure that patients have access to the safest and highest-quality care, regardless of how much they earn, where they live, how sick they are, or the color of their skin.
