BackgroundTo overcome the shortage of medical care delivery in the rapidly aging Japanese society, the Ministry of Health, Labour and Welfare in 2010 started to train the nurses to be able to conduct the specified medical acts. The Japanese Nursing Association conducted the educational program to train the wound, ostomy, and continence nurses for the specified medical act of wound care. However, the difference between wound, ostomy, and continence nurses who conducted the medical act and those who did not was not clear. The aim of this study was to determine how trained wound, ostomy, and continence nurses spend their time during their entire shift in an acute hospital setting.MethodsIn this prospective observational study, we selected those wound, ostomy, and continence nurses who received advanced training in the wound management program (T-WN) in 2011–2012. Wound, ostomy, and continence nurses who did not receive the training (N-WN) were also recruited as controls. We conducted a time and motion study during subject's day shifts for 1 week. We calculated the time spent on tasks based on a task classification code that was created to facilitate a two-group comparison.ResultsSix T-WNs and five N-WNs were our analysis subjects. T-WNs spent significantly more time on direct care than did N-WNs (p = 0.00). Moreover, in the sub-categories s of direct care, T-WN spent significantly more time on “treatment” than did N-WN (p = 0.01). T-WN spent significantly more time on treatment with (p = 0.03) or without (p = 0.01) physicians than did N-WN. In the treatment activities, T-WN performed significantly more time on foot care (p = 0.01), wound cleansing (p = 0.01) and conservative sharp wound debridement (p = 0.01) than did N-WN. Frequencies of direct care interventions for the patients was significantly different between T-WN and N-WN (p = 0.04).ConclusionsT-WNs frequently engaged in direct care provided treatment for patients with chronic wounds.

Observing small changes (SCs) at specific sites is a new form of managing changes in position. We investigated SCs at specific sites considering interface pressure, contact area, body alignment and physical sensation in nine healthy female adults and evaluated SCs using the air mattress that was divided into six cells (A-F). Thirty-three SC combinations at one or several sites were evaluated. Pressure in the sacral region significantly decreased in 28 SC combinations compared with the supine position (p < 0.05), and the effect of pressure redistribution was greater when SCs were applied at several instead of a single site. The contact area at 17 of the 28 SC combinations significantly increased (p < 0.05). Among sites ranked based on interface pressure, body alignment and physical sensation, SCs at sites BCE, AE and BD were the most favorable. The common feature among these three combinations was that they involved tilting the buttock region and one other site. The findings suggested that SCs at the buttock region could reduce disruptions in alignment as well as the impact on physical sensation caused by the body sinking into the mattress and improve interface pressure redistribution via increased contact area with the mattress.

Background and Objectives: For effective function of the rapid response system (RRS), prompt identification of patients at a high risk of cardiac arrest and RRS activation without hesitation are important. This study aimed to identify clinical factors that increase the risk of intensive care unit (ICU) transfer and cardiac arrest to identify patients who are likely to develop serious conditions requiring ICU management and appropriate RRS activation in Japan. Materials and Methods: We performed a single-center, case control study among patients requiring a rapid response team (RRT) call from 2017 to 2020. We extracted the demographic data, vital parameters, blood oxygen saturation (SpO2) and the fraction of inspired oxygen (FiO2) from the medical records at the time of RRT call. The patients were divided into two groups to identify clinical signs that correlated with the progression of clinical deterioration. Patient characteristics in the two groups were compared using statistical tests based on the distribution. Receiver operating characteristic (ROC) curve analysis was used to identify the appropriate cut-off values of vital parameters or FiO2 that showed a significant difference between-group. Multivariate logistic regression analysis was used to identify patient factors that were predictive of RRS necessity. Results: We analyzed the data of 65 patients who met our hospital’s RRT call criteria. Among the clinical signs in RRT call criteria, respiratory rate (RR) (p < 0.01) and the needed FiO2 were significantly increased (p < 0.01) in patients with severe disease course. ROC curve analysis revealed RR and needed FiO2 cut-off values of 25.5 breaths/min and 30%. The odds ratio for the progression of clinical deterioration was 40.5 times higher with the combination of RR ≥ 26 breaths/min and needed FiO2 ≥ 30%. Conclusions: The combined use of RR ≥ 26 breaths/min and needed FiO2 ≥ 30% might be valid for identifying patients requiring intensive care management.
