en Nursing Original Article <div style="text-align: justify;"><span style="font-size:12px;"><span style="font-family:Times New Roman;"><b>Background:</b> Standardized nursing languages, including NANDA International Nursing Diagnoses, Nursing Interventions Classification, and Nursing Outcomes Classification, provide a structured approach to enhancing the quality, consistency, and measurability of nursing care. Despite their recognized benefits, their systematic implementation in clinical practice remains limited. This study aimed to evaluate the effectiveness of a standardized nursing language-based training program in improving nurses&rsquo; clinical implementation of this framework.<br> <b>Methods:</b> A quasi-experimental study was conducted in 2024 at a tertiary hospital in Vietnam. A total of 120 eligible nurses were recruited into two groups: an intervention group and a control group. The intervention consisted of structured training focused on integrating standardized nursing languages into clinical documentation within the Nutrition and Safety/Protection domains. The primary outcome was the post-intervention utilization rate in nursing records. Data were collected using a structured record-review checklist and analyzed using descriptive statistics and chi-square tests at the 3-month follow-up assessment.<br> <b>Results:</b> At the 3-month follow-up, the proportion of nursing records using standardized nursing languages was significantly higher in the intervention group than in the control group (55/60 [91.7%] vs. 36/60 [60.0%], p < 0.001). Similar improvements were observed in both the Nutrition and Safety/Protection domains.<br> <b>Conclusion</b>: The structured training program was associated with a 31.7-percentage-point increase in the use of standardized nursing languages compared with usual practice. These findings suggest that terminology-focused educational interventions may facilitate the clinical adoption of standardized nursing languages and could be incorporated into continuing professional development and quality improvement initiatives. Further studies are needed to evaluate long-term sustainability and applicability across diverse healthcare settings.</span></span></div> Nurse Clinicians, NANDA‐I (Standardized Nursing Terminology) Nursing Diagnosis, Nursing Interventions Classification (Standardized Nursing Terminology), Nursing Outcomes Classification (Standardized Nursing Terminology), Standardised Nursing Terminology 0 0 http://nmj.goums.ac.ir/browse.php?a_code=A-10-2372-1&slc_lang=en&sid=1 Tran Thanh Liem Liemtran230571@gmail.com 100319475328460018776 100319475328460018776 No Nursing department, Da Nang Hospital, Da Nang city, Vietnam; Faculty of Nursing, Da Nang University of Medical Technology and Pharmacy, Da Nang city, Vietnam Luu Thi Thuy luuthithuy@dhktyduocdn.edu.vn 100319475328460018777 100319475328460018777 Yes Faculty of Nursing, Da Nang University of Medical Technology and Pharmacy, Da Nang city, Vietnam Nguyen Thi Phuc phucnguyenbvdn@gmai.com 100319475328460018778 100319475328460018778 No Nursing department, Da Nang Hospital, Da Nang city, Vietnam Thai Thi Thu Ha hathai1208@gmail.com 100319475328460018779 100319475328460018779 No Nursing department, Da Nang Hospital, Da Nang city, Vietnam Vo Thi Ha Tien Hatien1485@gmail.com 100319475328460018780 100319475328460018780 No Nursing department, Da Nang Hospital, Da Nang city, Vietnam Nguyen Thi Yen Hoai ntyhoai@dhktyduocdn.edu.vn 100319475328460018781 100319475328460018781 No Faculty of Nursing, Da Nang University of Medical Technology and Pharmacy, Da Nang city, Vietnam
