UNASSIGNED: Early and accurate identification of high-risk patients with peripheral intravascular catheter (PIVC)-related phlebitis is vital to prevent medical device-related complications.
UNASSIGNED: This study aimed to develop and validate a machine learning-based model for predicting the incidence of PIVC-related phlebitis in critically ill patients.
UNASSIGNED: Four machine learning models were created using data from patients ≥ 18 years with a newly inserted PIVC during intensive care unit admission. Models were developed and validated using a 7:3 split. Random survival forest (RSF) was used to create predictive models for time-to-event outcomes. Logistic regression with least absolute reduction and selection operator (LASSO), random forest (RF), and gradient boosting decision tree were used to develop predictive models that treat outcome as a binary variable. Cox proportional hazards (COX) and logistic regression (LR) were used as comparators for time-to-event and binary outcomes, respectively.
UNASSIGNED: The final cohort had 3429 PIVCs, which were divided into the development cohort (2400 PIVCs) and validation cohort (1029 PIVCs). The c-statistic (95% confidence interval) of the models in the validation cohort for discrimination were as follows: RSF, 0.689 (0.627-0.750); LASSO, 0.664 (0.610-0.717); RF, 0.699 (0.645-0.753); gradient boosting tree, 0.699 (0.647-0.750); COX, 0.516 (0.454-0.578); and LR, 0.633 (0.575-0.691). No significant difference was observed among the c-statistic of the four models for binary outcome. However, RSF had a higher c-statistic than COX. The important predictive factors in RSF included inserted site, catheter material, age, and nicardipine, whereas those in RF included catheter dwell duration, nicardipine, and age.
UNASSIGNED: The RSF model for the survival time analysis of phlebitis occurrence showed relatively high prediction performance compared with the COX model. No significant differences in prediction performance were observed among the models with phlebitis occurrence as the binary outcome.

BACKGROUND: Peripheral venous catheters (PVCs) remain the primary mode of short-term venous access for managing intravenous fluid, obtaining blood samples, and peripheral parenteral nutrition. They may get contaminated and require regular monitoring to prevent complications. This study evaluated the occurrence of phlebitis and its associated-clinical and microbiological indicators.
METHODS: The frequency of phlebitis was evaluated in hospitalized patients of both medical and surgical fields. Subsequently, the dichotomous association between the presence of phlebitis and the clinical aspects was investigated. In parallel, the bacterial contamination of PVCs was assessed through culture-based methods, microscopy observation, and 16S rRNA gene sequencing.
RESULTS: Approximately one in four patients presented phlebitis (28.4%). The most frequent symptom was erythema at access site, with or without pain, corresponding to Score 1 on the phlebitis scale (17.9%). Colonization of both lumen and external surface of PVC was observed in 31.3% of the samples. Staphylococcus and Pseudomonas were the most isolated bacterial genera on the PVC surface. No significant association was observed between the presence of phlebitis and the clinical aspects, as well as the presence of microorganisms.
CONCLUSIONS: Microorganism were present on both internal and external PVC surface, without being associated to phlebitis.

This study presents a deep learning model to predict phlebitis in patients with peripheral intravenous catheter (PIVC) insertions. Leveraging electronic health record data from 27,532 admissions and 70,293 PIVC events at a hospital in Seoul, South Korea, the study involved analyzing patient demographics, PIVC-specific features, and drug-related information. The developed deep learning model was benchmarked against various machine learning models, demonstrating superior performance with an accuracy of 0.93 and an AUC of 0.89. This highlights its potential as an effective tool for early detection of phlebitis, promising enhanced patient outcomes and healthcare efficiency.

UNASSIGNED: This study aimed to determine the incidence of peripheral intravenous catheter (PIVC)-induced phlebitis and its predictors among adult patients hospitalized at Dow University Hospital, Karachi, Pakistan.
UNASSIGNED: A sample of 258 adult patients admitted in the selected wards and planned for peripheral intravenous catheter insertion were recruited through consecutive sampling during March to May 2019. Daily follow-ups were performed to observe signs of phlebitis using a validated tool. The cohort was followed until discharge, removal of peripheral intravenous catheter, or study conclusion.
UNASSIGNED: Of 258 patients studied, 139 (53.9%) were females. A significant number of the participants 104 (40.3%) were young adults of age 20-40 years. The incidence of phlebitis was 39.1%. Tuberculosis (TB), peripheral intravenous catheter dwell time before initial assessment, administration of IV fluids, and dissatisfactory nursing care at Day 1 were associated significantly with the development of phlebitis. There was a doseresponse relationship between the catheter dwell time in hours before initial assessment and the development of phlebitis.
UNASSIGNED: This study found an increased incidence (39.1%) in three months of PIVC-induced phlebitis among adult patients. In addition to patient-related and PIVC-related risk factors considered in this study, PIVC-induced phlebitis is found to be significantly associated with the level of PIVC care provided by nurses. Continuous nursing education, developing standard care plans for PIVCs, and proper documentation of care are recommended.

BACKGROUND: Peripheral intravenous catheters (PIVCs) are the most commonly used vascular access device in hospitalised patients. Yet PIVCs may be complicated by local or systemic infections leading to increased healthcare costs. Chlorhexidine gluconate (CHG)-impregnated dressings may help reduce PIVC-related infectious complications but have not yet been evaluated. We hypothesise an impregnated CHG transparent dressing, in comparison to standard polyurethane dressing, will be safe, effective and cost-effective in protecting against PIVC-related infectious complications and phlebitis.
METHODS: The ProP trial is a multicentre, superiority, randomised clinical and cost-effectiveness trial with internal pilot, conducted across three centres in Australia and France. Patients (adults and children aged ≥6 years) requiring one PIVC for ≥48 hours are eligible. We will exclude patients with emergent PIVCs, known CHG allergy, skin injury at site of insertion or previous trial enrolment. Patients will be randomised to 3M Tegaderm Antimicrobial IV Advanced Securement dressing or standard care group. For the internal pilot, 300 patients will be enrolled to test protocol feasibility (eligibility, recruitment, retention, protocol fidelity, missing data and satisfaction of participants and staff), primary endpoint for internal pilot, assessed by independent data safety monitoring committee. Clinical outcomes will not be reviewed. Following feasibility assessment, the remaining 2624 (1312 per trial arm) patients will be enrolled following the same methods. The primary endpoint is a composite of catheter-related infectious complications and phlebitis. Recruitment began on 3 May 2023.
BACKGROUND: The protocol was approved by Ouest I ethic committee in France and by The Queensland Children\'s Hospital Human Research Ethics Committee in Australia. The findings will be disseminated through presentation at scientific conferences and publication in peer-reviewed journals.
BACKGROUND: NCT05741866.

Peripheral intravenous catheters (PIVCs) are the most commonly used invasive devices in acute care hospitals, with nurses being primarily responsible for the insertion and care of these devices. This point prevalence study aimed to describe current PIVC status and nursing documentation in a large, regional health care system and to explore variables associated with PIVC complications. The study was conducted with adult inpatients. There were 665 PIVCs included in the study. Dressings were clean, dry, and intact in 83% of observations; only 2.7% did not have a transparent dressing. Thirty-one percent of PIVCs were inserted in areas of flexion. Median dwell time was 2.39 days (± 2.36 days), with upper arm sites having the longest dwell time. Overall inter-rater reliability (IRR) for an infiltration or phlebitis score of 0 was high (97.4% and 92%, respectively). However, overall agreement was only 77.16% for infiltration and 40.07% for phlebitis, with significant disagreement as scores increased. Study findings support that there was strong compliance with the Infusion Nurses Society\'s (INS) Infusion Therapy Standards of Practice vascular access practice recommendations; however, opportunities to improve infiltration/phlebitis assessment and documentation exist.

OBJECTIVE: To determine the consensus and importance of care practices related to the management of peripheral venous catheter (PVC)-related phlebitis in hospitalized patients through the views of experts from different disciplines.
BACKGROUND: PVCs are commonly used in hospitals but are associated with complications such as phlebitis. Their management differs widely, and studies are heterogeneous.
METHODS: Delphi method.
METHODS: Four stages: problem area (with Web of Science bibliometric review in July 2022), panel members, two Delphi rounds and closing criteria. In the Delphi survey, experts answered an online questionnaire based on assessment, treatment and follow-up dimensions (September 2022-February 2023). Statistical analyses were conducted of frequencies, percentages, measures of central tendency and levels of dispersion (QD). A space for comments was created, and a thematic analysis conducted of them.
RESULTS: Eighteen experts (nurses, doctors and pharmacists) participated in the Delphi rounds. Forty-five activities were identified: 19 in assessment, 15 in treatment and 11 in follow-up. A high consensus level (QD ≤ 0.6) was found in five activities (11.12%), moderate level (0.6 < QD < 1.0) in 19 (42.22%) and low level (QD > 1.0) in 21 (46.66%). Seven themes were determined (patient perspective, lack of consensus, low evidence-based practices, stage-based treatments, prevention activities, high variability in practice and specialist teams and interdisciplinary work).
CONCLUSIONS: The importance of systematic assessment scales is highlighted together with consensus on signs and symptoms (pain, redness, inflammation, palpable cord and induration). Treatment according to severity and daily visual recording and monitoring are emphasized along with the need for patient participation and healthcare literacy. A high level of consensus was obtained in 11% of the activities, showing the large variability of criteria and interventions for phlebitis management. Highlighted needs include working in a team, the use of specialist teams and promoting evidence- and prevention-based activities.
CONCLUSIONS: Clinical variability is noted and, therefore, the importance of consensus on standardized care for PVC phlebitis and evidence-based practice.

Malnutrition is a common problem among hospitalized older patients. Peripheral parenteral nutrition (PN) can improve patient outcomes but can also lead to complications that affect future treatment. Older inpatients, in particular, are expected to be prone to these catheter-related complications. However, the impact of peripheral PN on older inpatients has been rarely investigated. In the current study, the impact of PN on short peripheral catheters (SPCs) was evaluated by comparing signs and symptoms at the time of catheter removal between 22 patients with PN and 27 without. In addition to external clinical assessment, sonographic investigations of the SPC site were performed. The prevalence of external signs and symptoms of complications was similar between the patients (all P > 0.05). However, subcutaneous edema was found by ultrasound in > 80% of patients with PN, compared with 55.6% of those without PN (P = 0.051). Unlike cases without PN, all patients with PN who presented with external signs and symptoms developed subcutaneous edema (P = 0.022). Multivariate analysis demonstrated that administration of PN was independently associated with subcutaneous edema (adjusted odds ratio = 6.88, 95% confidence interval = 1.083-75.486, P = 0.040). For several decades, phlebitis has been the primary focus of complications related to peripheral PN in clinical settings. However, our results imply that peripheral PN causes subcutaneous edema, which can lead to catheter failure in older inpatients. This study contributes to understanding the etiology of catheter failure during peripheral PN in this population.

This study aims to analyze the incidences of peripheral intravenous catheter-related phlebitis and infiltration and the associated risk factors in emergency departments. This descriptive cross-sectional, nonexperimental study was conducted with 300 participants in the emergency department of a university hospital in Türkiye between January 15 and February 15, 2018. The incidence of peripheral intravenous catheter-related phlebitis was 31%, which was grade 1 in 29.7% and grade 2 in 1.3% of the emergency department participants. Additionally, the incidence of peripheral intravenous catheter-related infiltration was 55.4%, including grades 1, 2, and 3 in 36.0%, 12.7%, and 6.7% of the participants, respectively. Incidences of phlebitis and infiltration were related to age, duration of peripheral intravenous catheterization longer than 24 hours, and repeated use of the catheter insertion site. The findings of this study may draw attention to the factors that trigger phlebitis and infiltration due to peripheral intravenous catheter insertions in the emergency department and may guide practices to prevent these complications before they develop. In this context, the Phlebitis Scale and Infiltration Scale developed by the Infusion Nurses Society are recommended to be used in the emergency department.
