Health Economics

  • (written as Complexity)
    In health technology assessments some technologies may be elusive in their nature (for example, VIHASA: values in health care - a spiritual approach [to staff training]), or multi-institutional (like many public health programmes) or have a pathway from cause to ultimate effect that is tortuous and not well understood, or are such as to engage a less than impartial commitment from analysts. In such cases, and from other sources of complexity as well, health economists have been seeking to develop non-trivial methods for assessing effectiveness and cost-effectiveness.
