PurposeThis study aimed to analyze and define the concept of readiness for hospital discharge (RHD) in patients with myocardial infarction (MI).Design/methodology/approachWalker and Avant's approach was used for concept analysis. Electronic text searches were performed using valid databases with “readiness for hospital discharge” and “MI” keywords. The research included quantitative and qualitative studies related to RHD published between 1997 and 2021 in English and Persian. Out of 103 obtained articles, 29 met the inclusion criteria.FindingsIn the analysis, the authors identified stable physical state, desirable individual and social conditions, psychological stability, adequate support, adequate information and knowledge, and multidisciplinary care as the attributes of the determinants of RHD. Antecedents were divided into two categories, including preadmission conditions (economic and social, etc.) and postadmission conditions (disease severity and patient health needs, etc). The consequences were also identified as both positive (e.g. self-care) and side effects (e.g. reduced readmission).Originality/valueThe results showed that the concept of RHD in MI patients is a complex and multidimensional condition that applies to all patients on discharge. It is critical for the care team to pay attention to its attributes and scopes in the process of preparing the patient for discharge. It is also suggested that the concept be used as a nursing diagnosis on the North American Nursing Diagnosis Association (NANDA) list. The Association provides nurses with an up-to-date list of nursing diagnoses.
