Risk factors for medical adhesive-related skin injury at the site of peripherally inserted central venous catheter placement in patients with cancer: a single-centre prospective study from China.

OBJECTIVES: This study aims to explore the incidence of, and risk factors for medical adhesive-related skin injury (MARSI) at peripherally inserted central venous catheter (PICC) sites in patients with cancer. DESIGN: A prospective observational cohort study was conducted at a tertiary hospital in Shenzhen, China. SETTING: This was a single-centre study conducted in a tertiary hospital in Shenzhen, China. PARTICIPANTS: A total of 340 patients with cancer and PICC placement from January 2022 to June 2023 were selected using a convenience sampling method. METHODS: Factors potentially associated with PICC-related MARSI (PICC-MARSI) were recorded, including patient demographics, and catheter placement and maintenance. Patients were divided into MARSI and non-MARSI groups. Univariate analysis was performed to screen for associated variables, and logistic regression analysis was used to identify independent risk factors for PICC-MARSI. RESULTS: Of all 340 patients enrolled, 33 (9.7%) developed PICC-MARSI, including skin tear (8, 24.2%), tension injury (5, 15.2%), irritant contact dermatitis (10, 30.3%), allergic dermatitis (7, 21.2%) and maceration (3, 9.1%). Multivariable analysis showed that age (OR=1.058, p=0.001, 95% CI 1.023-1.094), wet skin (OR=4.873, p=0.003, 95% CI 1.728-13.742), dry skin (OR=6.247, p<0.0001, 95% CI 2.239-17.431), oedema (OR=3.302, p=0.008, 95% CI 1.365-7.985), allergy history (OR=6.044, p=0.001, 95% CI 2.040-17.906), dressing type (OR=3.827, p=0.003, 95% CI 1.595-9.185), body mass index (BMI) <18.5 (OR=4.271, p=0.015, 95% CI 1.327-13.742) and BMI 25-30 (OR=2.946, p=0.027, 95% CI 1.131-7.678) were independent risk factors for PICC-MARSI. CONCLUSIONS: Proper catheter maintenance and appropriate dressing selection are crucial for the prevention of this condition.

Decreasing the incidence of delirium via multi-sensory stimulation in patients receiving mechanical ventilation in the intensive care unit: A protocol for a randomized feasibility study.

Introduction: Delirium is a common acute brain dysfunction syndrome in patients admitted to intensive care units (ICUs). Family engagement strategies, based on the theory of multi-sensory stimulation to ameliorate sensory deprivation in patients, may be an effective and scalable method to reduce the burden of delirium. Methods: /design: This is a assessor-blinded, randomised controlled trial of the feasibility of multi-sensory stimulation (MS) in patients with delirium. A total of 72 mechanically ventilated patients (n = 24 in each group) admitted to the ICU will be randomised to routine non-pharmacological delirium care (control), family multi-sensory stimulation and nurse multi-sensory stimulation groups. All participants except the control group will receive multi-sensory stimulation, including visual, auditory, tactile and kinesthetic stimulation, for 5 days. Our primary aim is to determine the feasibility of the study procedure (recruitment, eligibility, retention and attrition rates, appropriateness of clinical outcome measures), feasibility, acceptability and safety of the intervention (adverse events, satisfaction and other). Our secondary objective is to assess the preliminary efficacy of the MS protocol in reducing the incidence, duration and severity of delirium. Sedation levels and delirium severity will be assessed twice daily. Enrolled participants will be followed in hospital until death, discharge or up to 28 days after treatment. Ethics and dissemination: The current study was approved by the Ethics Review Board of Huazhong University of Science and Technology Union Shenzhen Hospital, China (KY-2023-031-01). The results of this study will be presented at scientific conferences and submitted for publication in peer-reviewed journals. Trial registration number: ChiCTR2300071457.
