Clinical meaning
Discharge planning is a systematic, interdisciplinary process that begins at the time of admission and ensures that patients are prepared for a safe transition from one level of care to another. The physiological basis for comprehensive discharge planning lies in understanding that patients recovering from acute illness or surgical intervention remain in a vulnerable physiological state at the time of hospital discharge. The stress response to illness activates the hypothalamic-pituitary-adrenal (HPA) axis, releasing cortisol and catecholamines that alter glucose metabolism, suppress immune function, and impair wound healing. These physiological effects persist beyond the acute hospital stay, making the post-discharge period a high-risk time for complications, medication errors, and hospital readmission. Research demonstrates that approximately 20% of patients discharged from hospital are readmitted within 30 days, and nearly 50% of these readmissions are considered preventable with adequate discharge planning. The most common reasons for preventable readmission include medication errors (patients taking incorrect doses, missing medications, or failing to fill prescriptions), inadequate understanding of warning signs requiring medical attention, premature discharge before physiological stability is achieved, and failure to establish follow-up appointments. Medication reconciliation is a patient safety process that involves comparing the medications a patient was taking before admission with those prescribed at discharge to identify and resolve discrepancies. Discrepancies include unintentional omissions (home medications not restarted), duplications (same medication class prescribed twice), interactions between new and home medications, and dosage changes that the patient does not understand. The teach-back method is an evidence-based communication strategy that confirms patient understanding by asking the patient to explain, in their own words, what they have been taught. Unlike simply asking 'Do you understand?' (which elicits a reflexive yes), the teach-back approach asks the patient to demonstrate comprehension: 'I want to make sure I explained this clearly. Can you tell me in your own words how you will take this new medication?' Health literacy, which is the ability to obtain, process, and understand basic health information, is a critical factor in discharge planning. Approximately 36% of adults have limited health literacy, meaning they may not be able to read medication labels, follow written discharge instructions, or understand when to seek emergency care. The practical nurse must assess health literacy without embarrassment to the patient and tailor education accordingly, using plain language, visual aids, and demonstration. Psychosocial assessment is equally important: patients discharged to unsafe home environments, those without adequate social support, those with untreated mental health conditions, and those with financial barriers to obtaining medications or follow-up care are at highest risk for adverse outcomes. The practical nurse plays a critical role in identifying these barriers and communicating them to the discharge planning team.
