It is better to use an evidence-based evaluation method to identify the best and most applicable nursing theory or model. Therefore, this discussion is widely based on an evidence-based evaluation of the Orem’s theory as a health promotion model.
In the assessment of any theory, it is better first to determine whether it is compatible with the nursing care standards and practices in the modern practices (Fawcett &Desanto-Madeya, 2012).

In regards to evidence-based evaluation, this model uses current evidence provided in various nursing sources to make the decisions regarding the community and personal healthcare delivery (Fawcett &Desanto-Madeya, 2012). Some of the best current evidence used by the model includes the valid research about the health care effects, health problems relating to various pollutants, and the best and accurate diagnostic tests for different health issues (Sakraida, 2010). Consequently, the health promotion model provides good guidelines on how nursing may be upgraded regarding the standards and patients '
