Introduction: It is unclear why 17% of the patients with COPD exacerbation treated in Danish hospitals have a new hospitalization within 30 days. Hospital discharge is multifaceted; however, the processes and nurses' efforts may be important factors in a successful transition from hospital to home. 

Aim: To investigate nurses' efforts and strategies when ending hospital courses of patients with COPD from a medicinal pulmonary ward. 

Method: A Kathy Charmaz-inspired constructivist grounded theory study with participant observation of eleven female nurses (mean age 32 years) from two different medicinal lung wards in Denmark, has been carried out. 

Results: A context-specific theory of nurses? typologies when patients with COPD are discharged from a pulmonary medical ward was found. The theory contains three different typologies: "To be co-creating", "To be hesitating", and "To be socializing". Four critical factors across all three typologies have been identified in discharge of patients; goal, workflow, values and communication. "To be co-creating" has the goal of excellence, safety and sustainability in the discharge of patients; the workflow is based on collaboration with a dialogue-based communication, and the value basis is bio-psycho-social, which is expressed in the nurse's reflexivity and systematic interventions. 

Conclusion: By drawing on these data, we argue that the "To be co-creating" typology is the most all-encompassing typology. "To be co-creating" is based upon systematics and patient involvement, which the literatures find essential for preventing readmittances.
