The complexity of health problems such as childhood cancer poses challenges in health care and in the evaluation of interventions. This situation is aggravated if policy makers and decision makers assume that a healthcare system works in a delimited environment with defined rules. The approach to childhood cancer in Colombia required the promulgation of a law to contribute to the reduction of mortality from this cause with implications for nursing. This study characterized its complex nature, evidenced the potential implications in its evaluation and proposed an evaluation scheme. Methods: Documentary research with related information available between the years 2010 and 2020. Bowen's guidelines for the analysis of the information were followed, the categories included were relevant actors, context, components, organizational levels involved and results. Results: The analysis of the prob...
