Evaluation the mean alteration trends and validation of nine equivalents of nursing manpower use score in medical patients of intensive care units

Introduction: Scoring systems are considered as a guideline for caring personnel in intensive care units (ICU) to evaluate patients’ status or estimate recovery chance. Nine Equivalents of Nursing Manpower Use Score (NEMS) is one of these systems. Considerably, the credits of obtained scores of NEMS in different days after patients’ admission or deciding about current status of patients according to previous scores of NEMS are not clear properly. So, this study was performed to evaluate the mean alteration trends and credit of Nine Equivalents of NEMS in internal patients’ admission in intensive care units. Materials and Methods: In a descriptive-prospective study, the information of 156 patients that admitted in critical care units of Edalatian hospital of Mashhad city, were calculated and recorded until 7 days according to demographic questionnaire and NEMS.  A purposeful sampling method was adopted and all eligible patients were included. Then using the ROC curve, the validity of daily NEMS scores of patients were demonstrated. Results: The curve of mean alteration trends of NEMS of expired patients was increased and for discharged patients was decreased during seven days of admission in ICU. Also, the ROC curve showed that with increasing duration of hospital stay, NEMS ability to diagnosis of critically ill patients was improved. Conclusion:  The credit of NEMS increases with duration of hospital staying. So, it is suggested when using the NEMS, the scores of final days of hospitalization in ICU be considered more seriously
