Meikirch model: new definition of health as hypothesis to fundamentally improve healthcare delivery.

The unrelenting rise in healthcare costs over the past 50 years has caused policymakers to respond. Their reactions have led to a gradual economic transformation of medicine. As a result, detailed billing, quality controls, financial incentives, savings targets and digitalisation are now putting increasing pressures on the nursing and medical staff. In addition, the humanity of care of the patient-doctor and/or patient-nurse interactions has been cast aside to a great extent. Therefore, the immaterial side of care has been neglected or even removed from these relationships. These changes are now perceived as intolerable by most health workers and patients. Yet healthcare costs are still rising. This paper presents a hypothesis that should enable healthcare systems to respond more effectively. It proposes the introduction of the Meikirch model, a new comprehensive definition of health. The Meikirch model takes human nature fully into account, including health and disease. The inclusion of the individual potentials, the social surroundings and the natural environment leads to the concept of health as a complex adaptive system (CAS). Care for such a definition of health requires medical organisations to change from top-down management to bottom-up leadership. Such innovations are now mature and ready for implementation. They require a long-term investment, a comprehensive approach to patient care and new qualifications for leadership. The Meikirch model reads: 'To be healthy a human individual must be able to satisfy the demands of life. For this purpose, each person disposes of a biologically given and a personally acquired potential, both of which are closely related to the social surroundings and the natural environment. The resulting CAS enables the individual to unfold a personal identity and to develop it further until death. Healthcare has the purpose to empower each individual to fully realize optimal health'. This hypothesis postulates that the new definition of health will further develop healthcare systems in such a way that better health results at lower costs.
