This study aimed to elucidate the gap in terminology between acute and long-term care (LTC) hospitals. Fifty-seven hospital documents were analyzed using text mining. Each document contained a mean 194.2 terms. Acute care hospital documents often contain pharmacological information. LTC hospital documents often contain information related to patients' lives. Documents from both settings used local, non-standardized language. Our results suggest that expanding the national standard of nursing terminologies has potential for enhancing continuity of care.
