Abstract :The fall risks of patients hospitalized for psychiatric disorders are often assessed using fall risk assessment tools that are not validated for psychiatric inpatients. This study aimed to assess the predictive validity of a modified Japanese Nursing Association (JNA) fall risk assessment tool and its short forms at different observation points (7, 14, 21, and 28 days) among patients admitted to a neuropsychiatry ward in a Japanese university hospital. This study utilized a retrospective cohort design. Participants were patients aged≧15 years, who were admitted between February 20, 2009 and December 31, 2016. Incident reports were reviewed to identify falls. The predictive validity was assessed using the area under the receiver operating characteristics curve, sensitivity, specificity, and positive and negative likelihood ratios at the cut-off points of≧6 and≧7 for the modified risk assessment tool,≧3and≧5 for the short-form ver. 1, and≧4 and≧5 for the short-form ver.2. We found that neither the modified JNA tool, nor its short versions, achieved optimal sensitivity and specificity values of greater than 0.70 among 1,003 patients (median age 41 years, 71%women). The area under the receiver operating characteristics curves showed the highest values at the 7-day observation point in all three tools. The findings from this study suggest that fall risk assessment tools with sufficient predictive validity in non-psychiatric settings may not achieve an equivalent level of validity among psychiatric patients, and a different cut-off point may need to be considered.
