Preventing peripheral intravenous catheter failure by reducing mechanical irritation.

ABSTRACT: Peripheral intravenous catheter failure is a significant concern in the clinical setting. We investigated the effectiveness of care protocols, including an ultrasonographic "pre-scan" for selecting a large-diameter vein before catheterization, a "post-scan" for confirming the catheter tip position after catheterization with ultrasonography, and the use of a flexible polyurethane catheter to reduce the mechanical irritation that contributes to the incidence of catheter failure. This intervention study was a non-randomized controlled trial to investigate the effectiveness of the abovementioned care protocols, the effects of which were compared to the outcomes in the control group, which received conventional care. For both groups, participants were selected from patients in two wards at the University of Tokyo in Japan between July and November 2017. Inverse probability score-based weighted methods (IPW) using propensity score were used to estimate the effectiveness of care protocols. The primary outcome was catheter failure, which was defined as accidental and unplanned catheter removal. We used Kaplan-Meier survival curves to compare rates of time until catheter failure. We analysed 189 and 233 catheters in the intervention and control groups, respectively. In the control group, 68 catheters (29.2%) were determined to have failed, whereas, in the intervention group, only 21 catheters (11.1%) failed. There was a significant difference between each group regarding the ratio of catheter failure adjusted according to IPW (p?=?0.003). The relative risk reduction of the intervention for catheter failure was 0.60 (95% CI: 0.47-0.71). Care protocols, including assessment of vein diameter, vein depth, and catheter tip location using ultrasound examination for reducing mechanical irritation is a promising method to reduce catheter failure incidence.

Project description:ObjectivePeripheral intravenous catheter (PIVC) failure occurs frequently, but the underlying mechanisms of failure are poorly understood. We aim to identify ultrasonographic factors that predict impending PIVC failure prior to clinical exam.MethodsWe conducted a single site prospective observational investigation at an academic tertiary care center. Adult emergency department (ED) patients who underwent traditional PIVC placement in the ED and required admission with an anticipated hospital length of stay greater than 48 hours were included. Ongoing daily PIVC assessments included clinical and ultrasonographic evaluations. The primary objective was to identify ultrasonographic PIVC site findings associated with an increased risk of PIVC failure. The secondary outcome was to determine if ultrasonographic indicators of PIVC failure occurred earlier than clinical recognition of PIVC failure.ResultsIn July and August of 2020, 62 PIVCs were enrolled. PIVC failure occurred in 24 (38.71%) participants. Multivariate logistic regression demonstrated that the presence of ultrasonographic subcutaneous edema [AOR 7.37 (1.91, 27.6) p = 0.0030] was associated with an increased likelihood of premature PIVC failure. Overall, 6 (9.67%) patients had subcutaneous edema present on clinical exam, while 35 (56.45%) had subcutaneous edema identified on ultrasound. Among patients with PIVC failure, average time to edema detectable on ultrasound was 46 hours and average time to clinical recognition of failure was 67 hours (P = < 0.0001).ConclusionsPresence of subcutaneous edema on ultrasound is a strong predictor of PIVC failure. Subclinical subcutaneous edema occurs early and often in the course of the PIVC lifecycle with a predictive impact on PIVC failure that is inadequately captured on clinical examination of the PIVC site. The early timing of this ultrasonographic finding provides the clinician with key information to better anticipate the patient's vascular access needs. Further research investigating interventions to enhance PIVC survival once sonographic subcutaneous edema is present is needed.

Project description:INTRODUCTION:Peripheral intravenous catheters (PIVCs) are frequently used in hospitals. However, PIVC complications are common, with failures leading to treatment delays, additional procedures, patient pain and discomfort, increased clinician workload and substantially increased healthcare costs. Recent evidence suggests integrated PIVC systems may be more effective than traditional non-integrated PIVC systems in reducing phlebitis, infiltration and costs and increasing functional dwell time. The study aim is to determine the efficacy, cost-utility and acceptability to patients and professionals of an integrated PIVC system compared with a non-integrated PIVC system. METHODS AND ANALYSIS:Two-arm, multicentre, randomised controlled superiority trial of integrated versus non-integrated PIVC systems to compare effectiveness on clinical and economic outcomes. Recruitment of 1560 patients over 2?years, with randomisation by a centralised service ensuring allocation concealment. Primary outcomes: catheter failure (composite endpoint) for reasons of: occlusion, infiltration/extravasation, phlebitis/thrombophlebitis, dislodgement, localised or catheter-associated bloodstream infections. SECONDARY OUTCOMES:first time insertion success, types of PIVC failure, device colonisation, insertion pain, functional dwell time, adverse events, mortality, cost-utility and consumer acceptability. One PIVC per patient will be included, with intention-to-treat analysis. Baseline group comparisons will be made for potentially clinically important confounders. The proportional hazards assumption will be checked, and Cox regression will test the effect of group, patient, device and clinical variables on failure. An as-treated analysis will assess the effect of protocol violations. Kaplan-Meier survival curves with log-rank tests will compare failure by group over time. Secondary endpoints will be compared between groups using parametric/non-parametric techniques. ETHICS AND DISSEMINATION:Ethical approval from the Royal Brisbane and Women's Hospital Human Research Ethics Committee (HREC/16/QRBW/527), Griffith University Human Research Ethics Committee (Ref No. 2017/002) and the South Metropolitan Health Services Human Research Ethics Committee (Ref No. 2016-239). Results will be published in peer-reviewed journals. TRIAL REGISTRATION NUMBER:ACTRN12617000089336.

Project description:ObjectivesThis study aimed to describe the translation process and establish the validity of the three instruments in Indonesian to assess pediatric peripheral intravenous catheter (PIVC) insertion and care practices.MethodsThe six-step forward and backward translation method was used to translate the adapted questionnaires. The English version questionnaires included the point prevalence audit checklist, the nurse survey consisting of the nurse PIVC knowledge questionnaire and the nurse PIVC confidence questionnaire, plus a Patient/parent Experience Survey. Data collection was conducted in Indonesia between October 2019 and February 2020. In total, there were six translators (two for each instrument), nine-panel vascular access experts (three for each instrument), and 30 participants (ten for each instrument) of the target population involved in the translation and validation of the three instruments. Three-panel experts rated the content relevance of each instrument using a four-point rating scale. Item level and scale level content validity index and kappa index were calculated. Ten-panel members of the target population evaluated each questionnaire regarding feasibility, clarity, logical sequence, and formatting. Qualitative comments from the panel were also reviewed.ResultsThe translation process indicated relatively low discrepancies between translators except for semantic equivalence. There were nine, eight, and one semantic discrepancies found in the forward translation of the point prevalence audit checklist, nurse survey, and patient/parent experience survey. The semantic discrepancies were less prevalent in the backward translation, with only one, three, and two items reported during the process. The item validity index for all of the three instruments showed relatively high agreement between experts (I-CVI > 0.78, S-CVI/Ave >0.90, S-CVI/UA > 0.70, and kappa index >0.74). The face validity was established with the panel reporting that the three instruments were easy to understand and presented logically. However, some re-formatting of the nurse survey and patient/parent experience survey were needed to avoid ambiguity and confusion for the participants.ConclusionsThe results indicate that the translated three survey instruments that had been widely used in other developed countries show good content validity in the Indonesian context. They can be used as a reference for further testing in different countries and contribute to understanding the pediatric PIVC audit tools used in future clinical research.

Project description:BackgroundOne-third of peripheral intravenous catheters (PIVCs) fail from inflammatory or infectious complications, causing substantial treatment interruption and replacement procedures.ObjectivesWe aimed to compare complications between integrated PIVCs (inbuilt extension sets, wings, and flattened bases) and traditional nonintegrated PIVCs.Designs, settings and participantsA centrally randomized, controlled, superiority trial (with allocation concealment until study entry) was conducted in three Australian hospitals. Medical-surgical patients (one PIVC each) requiring intravenous therapy for >24 h were studied.Main outcome measuresThe primary outcome was device failure (composite: occlusion, infiltration, phlebitis, dislodgement, local, or bloodstream infection). Infection endpoints were assessor-masked. The secondary outcomes were: failure type, first-time insertion success, tip colonization, insertion pain, dwell time, mortality, costs, health-related quality of life, clinician, and patient satisfaction.ResultsOut of 1759 patients randomized (integrated PIVC, n = 881; nonintegrated PIVC, n = 878), 1710 (97%) received a PIVC and were in the modified intention-to-treat analysis (2269 PIVC-days integrated; 2073 PIVC-days nonintegrated). Device failure incidence was 35% (145 per 1000 device-days) nonintegrated, and 33% (124 per 1000 device-days) integrated PIVCs.InterventionIntegrated PIVCs had a significantly lower failure risk (adjusted [sex, infection, setting, site, gauge] hazard ratio [HR]: 0.82 [95% confidence interval, CI: 0.69-0.96], p = .015). The per-protocol analysis was consistent (adjusted HR: 0.80 [95% CI: 0.68-0.95], p = .010). Integrated PIVCs had significantly longer dwell (top quartile ≥ 95 vs. ≥84 h). Mean per-patient costs were not statistically different.ConclusionsPIVC failure is common and complex. Significant risk factors include sex, infection at baseline, care setting, insertion site, catheter gauge, and catheter type. Integrated PIVCs can significantly reduce the burden of PIVC failure on patients and the health system.

Project description:BACKGROUND:Peripheral intravenous catheters (PIVCs) are ubiquitous medical devices, crucial to providing essential fluids and drugs. However, post-insertion PIVC failure occurs frequently, likely due to inconsistent maintenance practice such as flushing. The aim of this implementation study was to evaluate the impact a multifaceted intervention centred on short PIVC maintenance had on patient outcomes. METHODS:This single-centre, incomplete, stepped wedge, cluster randomised trial with an implementation period was undertaken at a quaternary hospital in Queensland, Australia. Eligible patients were from general medical and surgical wards, aged ??18?years, and requiring a PIVC for >?24?h. Wards were the unit of randomisation and allocation was concealed until the time of crossover to the implementation phase. Patients, clinicians, and researchers were not masked but infections were adjudicated by a physician masked to allocation. Practice during the control period was standard care (variable practice with manually prepared flushes of 0.9% sodium chloride). The intervention group received education reinforcing practice guidelines (including administration with manufacturer-prepared pre-filled flush syringes). The primary outcome was all-cause PIVC failure (as a composite of occlusion, infiltration, dislodgement, phlebitis, and primary bloodstream or local infection). Analysis was by intention-to-treat. RESULTS:Between July 2016 and February 2017, 619 patients from 9 clusters (wards) were enrolled (control n?=?306, intervention n?=?313), with 617 patients comprising the intention-to-treat population. PIVC failure was 91 (30%) in the control and 69 (22%) in the intervention group (risk difference -?8%, 95% CI -?14 to -?1, p?=?0.032). Total costs were lower in the intervention group. No serious adverse events related to study intervention occurred. CONCLUSIONS:This study demonstrated the effectiveness of post-insertion PIVC flushing according to recommended guidelines. Evidence-based education, surveillance and products for post-insertion PIVC management are vital to improve patient outcomes. TRIAL REGISTRATION:Trial submitted for registration on 25 January 2016.
