Objective: To evaluate the accuracy of the defining characteristics of the nursing diagnosis Impaired skin integrity (00046) in patients admitted to intensive care units (ICUs)., Methods: A cross-sectional diagnostic accuracy study was conducted with 105 adult patients admitted to an ICU. A latent class model with random effects was used to test the sensitivity and specificity of the defining characteristics investigated. The diagnosis Impaired skin integrity (00046) was the dependent variable, whereas sociodemographic and clinical data were the independent variables., Results: Impaired skin integrity was present in 3.75% of the sample. The defining characteristic with the best accuracy for the diagnosis was dry skin, with high sensitivity (0.9994) and specificity (0.9106). Other characteristics stood out in terms of sensitivity measures: altered skin color (0.9994) and foreign matter piercing skin (0.9994). In terms of specificity, the following stood out: desquamation (1.000), localized area hot to touch (0.9901), pruritus (0.9897), bleeding (0.9802), and hematoma (0.9208)., Conclusion: The defining characteristics that helped infer the diagnosis Impaired skin integrity (00046) with greater certainty were dry skin, altered skin color, foreign matter piercing skin, desquamation, localized area hot to touch, pruritus, bleeding, and hematoma., Implications for Nursing Practice: Identifying defining characteristics with high diagnostic accuracy for Impaired skin integrity (00046) enables nurses to expand their clinical perspective on this dysfunction, which can affect the skin of critically ill patients, and to develop individualized care plans., (© 2025 NANDA International, Inc.)

Objective: Evaluate the impairment of tissue integrity in patients with diabetic foot and verify its association with time of diagnosis of the disease., Methods: Cross-sectional study conducted with 134 patients in an outpatient clinic located in the Northeast region of Brazil. A semi-structured questionnaire was used for data collection, which was subjected to descriptive analysis and the Mann-Whitney U non-parametric test., Results: Indicators with the lowest average score were: skin temperature, sweating, skin lesions, right and left pedal pulses, right and left tibial pulses. Patients less than ten years old had worse scores on thickness, elasticity, right tibial pulse and tissue integrity. Those with a diagnosis time of more than ten years had a greater impairment of sensation and right pulse., Conclusion: All indicators showed some impairment of tissue integrity, and the time of diagnosis of the disease was associated with six of these.

Objectives: to verify the association between knowledge and adherence to foot self-care practices performed by patients with diabetes mellitus type 2., Methods: cross-sectional, descriptive study carried out with 197 patients in basic health units located in the Northeast region of Brazil. For data collection, we used a semi-structured questionnaire that addressed issues inherent to knowledge and Diabetes Self-Care Activities., Results: we observed that patients with moderate knowledge about self-care practices were more likely to perform foot self-examination, dry the interdigital spaces, moisturize their feet with creams and oils, observe the presence of mycosis and ingrown toenail when compared to patients with insufficient knowledge., Conclusions: the patients' level of knowledge was closely related to the self-care activities carried out, which reinforces the importance of nurses working on training those on essential health care.

Purpose: To evaluate the benefits of NIC interventions in postoperative patients with ineffective airway clearance (00031)., Methods: Quasi-experimental study with interrupted time-series design. A total of 101 patients were evaluated during 4 days based on the nursing outcome Respiratory Status: Airway Patency (0410)., Findings: Interventions such as cough enhancement (3250), ventilation assistance (3390), and airway management (3140) contributed to significative improvements of the patients' airway patency. Site of surgery and patients' intrinsic characteristics were proven to have influence in the NOC ratings., Conclusions: Interventions implemented during the research contributed to improvement of clinical indicators of airway patency., Implications for Nursing Practice: Postoperative respiratory complications can be minimized by the use of standardized nursing languages., (© 2019 NANDA International, Inc.)
