Ethical Principles

The Population Health Impact Institute will strive for the highest ethical standards by following our "Code of Evaluation Ethics" and abiding by the "Operating Principles" established at our founding.

The PHI Institute will promote adoption of these principles among individuals and groups throughout the health services industry.

Code of Evaluation Ethics

The Population Health Impact Institute recognizes that many forms of error and bias can influence the evaluation process and resulting outcomes.

To reduce such influences, the I / we pledge to adhere to these three core principles:

  1. Objectivity. I / we shall strive for objectivity and will make a concerted effort to minimize the intentional introduction of personal, organizational, and methodological biases.
  2. Disclosure of Methods. I / we shall make every effort to describe in detail all relevant methods and measurement parameters used in our impact assessments which may influence outcome results.
  3. Disclosure of Interests. I / we shall disclose any significant personal, organizational or financial interests which we believe may directly or indirectly influence our judgment.

Adherence to these core principles will serve to advance credible and defensible decisions regarding the allocation and efficient delivery of health services for any defined population.

Original Operating Principles

  • Independence … through balanced leadership on the Institute's Board of Directors and by the avoidance of “entangling alliances.”
  • Transparency … of methods, processes, outcomes, and interests.
  • Impartiality … by reduction of potential and actual “conflict of interests” by not engaging in consulting services (e.g., helping clients improve programs, methodologies, processes or outcomes.) and then engage in scoring the extent to which that same client has adhered to principles.
  • Transcendency … by cooperation and collaboration among different, even competing organizations, including accreditation groups, trade associations, and provider organizations.
  • Credibility… through the application of science-based principles and practices: Nullius in Verba.
  • Utility … “Let the market decide” based upon open disclosure of information, methods and the above operating principles.

References for Quotes:

1660: “Nullius in Verba” is the credo of the Royal Society of London; it is translated as “Don’t take anyone’s word for it”—reflecting a scientific commitment to replicable evidence-based decision making rather than non-replicable eminence -based decision making.

1776: Adam Smith is the primary source of the economic maxim “let the market decide.”

1796: The plea to avoid “entangling alliances” is from President George Washington’s Farewell Address to his new nation.
