AIM: To identify the competencies required for hospital-based WOC nurses to provide direct pressure injury (PI) care in home care settings in Japan. DESIGN: Mixed methods convergent design. METHODS: The qualitative strand used a descriptive design to explore competencies for overcoming barriers faced by hospital-based WOC nurses when providing PI care at home. The quantitative strand used a cross-sectional design to assess competencies in organising the hospital PI management system. RESULTS: Six competencies were identified: (1) Establish relationships with home healthcare professionals; (2) Promote hospital-based WOC nurse's expertise to home healthcare professionals; (3) Collaborate with the regional medical liaison office in WOC nurse's hospital; (4) Involve hospital administrators in home PI management; (5) Utilise social media/Information and Communication Technology for patient or home-visiting nurse communication; and (6) Utilise public or academic support projects to facilitate home-based activities. The median scoring rate for each medical staff domain on the revised Collaboration Competency Scale for WOC Nurses ranged from 80% to 91%. CONCLUSION: The results of this study can serve as a practical resource to help WOC nurses expand their activities into home-care settings. IMPLICATIONS FOR THE PROFESSION: Their ability to coordinate with staff and manage PI care within hospitals supports active engagement in home care, improving continuity and quality. IMPACT: This study addressed the issue that many hospital-based WOC nurses cannot visit patients at home. The competencies identified may enable these nurses to expand their role into home care. REPORTING METHOD: This study followed EQUATOR guidelines, with the STROBE Statement applied to the quantitative part and the COREQ checklist to the qualitative part. PATIENT OR PUBLIC CONTRIBUTION: Patients or the public were not involved in the study's design, conduct, or reporting.

OBJECTIVES: The taxane chemotherapeutic agent docetaxel has been used as a therapy for various cancers. Some patients receiving docetaxel develop serious problems with fluid retention, which leads to peripheral edema formation, reducing the patient's quality of life. This study investigated the effect of docetaxel administration on fluid dynamics in mice as a step toward developing advanced preventive measures in nursing. METHODS: Mice were administered 10 mg/kg/day of docetaxel intravenously for 5 days as the intervention group or with normal saline as the control group. To investigate fluid dynamics on day 5, the leakage of blood plasma, interstitial fluid volume, and fluid transportation capacity into lymph vessels were evaluated and compared between the two groups. RESULTS: The Miles assay with Evans Blue, an albumin-binding dye, revealed that leakage of blood plasma was significantly increased in the control group compared with the intervention group (p<0.01). Results of the interstitial fluid volume and fluid transportation capacity were similar between the two groups, but the fluid transportation capacity tended to be higher in the intervention group. CONCLUSIONS: Docetaxel administration in our mouse model caused the leakage of blood plasma without proteins from the blood vessels into the interstitial tissues, which appeared at the initial stage of edema formation. This model might be useful for assessing the leakage of blood plasma and, subsequently, the development of preventive measures against edema formation.

BACKGROUND: The use of mobile apps to promote knowledge level, practice, and behavioral change potential has become increasingly common. However, studies on apps targeting social welfare employees working in the home-care setting to prevent pressure injury (PI) are lacking. The care manager (CM) plays a key role in connecting the demand and supply of home-care services. PI is more prevalent in the home-care setting, where resources are limited, than in acute settings. OBJECTIVE: The research hypothesis was that CMs who use a mobile app will have improved general knowledge and heightened practice for PI prevention, compared to that before using the app. This study aimed to assess the effectiveness of a PI prevention support mobile app prototyping model (Pips-Map) in improving the knowledge level, practice, and behavioral change potential of CMs in PI prevention in the home-care setting. METHODS: This was conducted between December 2021 and December 2023 as a single-arm, pre-post pilot study including 27 CMs who worked in a Japanese city. Pips-Map was used for 6 months in daily practice, and a self-administered test questionnaire was used to assess participants' knowledge and practice in PI prevention before or after using Pips-Map. At the end of the posttest, a validated App Behavior Change Scale was used to analyze behavioral change potential. This study followed the Consolidated Standards of Reporting Trials (CONSORT) extension to pilot and feasibility trials. RESULTS: In total, 19 participants were analyzed. Out of 55 points, the total mean knowledge score significantly increased from 30.9 (SD 5.9) in the pretest group to 36.1 (SD 5.9) in the posttest group (P=.0003). The number of participants with a total score of >70% (adequate knowledge level) increased from 2 (11%) to 7 (36.8%), but the difference was not statistically significant (P=.07). For the level of practice, out of 21 points, the total score increased from 15.2 (SD 3.1) in the pretest group to 16.2 (SD 3.0) in the posttest group, but no statistically significant differences were observed (P=.16). The behavior change scale revealed that participants positively evaluated the Pips-Map to provide information on PI prevention guidelines but had concerns regarding inadequate usability and financial incentives of Pips-Map. CONCLUSIONS: The use of Pips-Map for 6 months in actual practice increased the knowledge level of Japanese CMs in PI prevention, but it did not change the level of practice. Considering the need for updating apps that aim to promote behavioral change, this study identified some limitations of Pips-Map. Thus, revisions must be made to adapt Pips-Map to home-based care needs.

This study aimed to examine the constipation detection accuracy of ultrasonography for elderly people who cannot clearly communicate their symptoms. We searched for studies, including longitudinal observational studies, cross-sectional studies, and case-control studies, on MEDLINE（via PubMed）, The Cochrane Library/ CENTRAL, Ichushi-Web, Embase, CINAHL, and the Cochrane Database of Systematic Reviews. We included studies that investigated the detection accuracy of ultrasonography for fecal retention in English and Japanese. The sensitivity and specificity of ultrasonography as a constipation assessment tool were calculated in each included study, and their pooled estimated values were determined. Six studies were included in the qualitative analysis. Ultrasonography was conducted once a day or before defecation. The pooled sensitivity and specificity of detecting constipation by ultrasonography were 0.93（95% CI: 0.63-0.99）and 0.81（95% CI: 0.60-0.92）, respectively. However, the overall certainty of evidence in the included studies was very low. Ultrasonography showed a high constipation detection accuracy, which may be a useful assessment tool in clinical settings because of its portability and noninvasiveness. Future studies are needed to improve the evidence level.
