PURPOSE To establish technical values for nursing diagnoses in primary healthcare with which to weight the delivery of care based on criteria of complexity and relevance. METHODS A three‐phase cross‐sectional descriptive study: (1) establishing and weighting of the assessment criteria of technical values, (2) scoring of the assessment criteria per diagnosis, and (3) assigning technical values. FINDINGS Diagnoses were ordered on the scoring scale obtained and a technical value of 1 to 4 was assigned according to their quartile. CONCLUSIONS Having a technical value for each nursing diagnosis helps to measure the diversity and complexity of care. IMPLICATIONS FOR NURSING PRACTICE Technical values may contribute to improving nursing management indicators, as they incorporate a quantitative view into the assessment process.
