Incidência de complicações locais no cateterismo venoso periférico e fatores de risco associados

Peripheral intravenous catheter infection and failure: A systematic review and meta-analysis

BACKGROUND

Peripheral intravenous catheters are the most frequently used invasive device in nursing practice, yet are commonly associated with complications. We performed a systematic review to determine the prevalence of peripheral intravenous catheter infection and all-cause failure.

METHODS

The Cochrane Library, PubMed, CINAHL, and EMBASE were searched for observational studies and randomised controlled trials that reported peripheral intravenous catheter related infections or failure. The review was limited to English language and articles published from the year 2000. Pooled estimates were calculated with random-effects models. Meta-analysis of observation studies in epidemiology guidelines and the Cochrane process for randomised controlled trials were used to guide the review. Prospero registration number: CRD42022349956.

FINDINGS

Our search retrieved 34,725 studies. Of these, 41 observational studies and 28 randomised controlled trials (478,586 peripheral intravenous catheters) met inclusion criteria. The pooled proportion of catheter-associated bloodstream infections was 0.028 % (95 % confidence interval (CI): 0.009-0.081; 38 studies), or 4.40 catheter-associated bloodstream infections per 100,000 catheter-days (20 studies, 95 % CI: 3.47-5.58). Local infection was reported in 0.150 % of peripheral intravenous catheters (95 % CI: 0.047-0.479, 30 studies) with an incidence rate of 65.1 per 100,000 catheter-days (16 studies; 95 % CI: 49.2-86.2). All cause peripheral intravenous catheter failure before treatment completion occurred in 36.4 % of catheters (95 % CI: 31.7-41.3, 53 studies) with an overall incidence rate of 4.42 per 100 catheter days (78,891 catheter days; 19 studies; 95 % CI: 4.27-4.57).

INTERPRETATION

Peripheral intravenous catheter failure is a significant worldwide problem, affecting one in three catheters. Per peripheral intravenous catheter, infection occurrence was low, however, with over two billion catheters used globally each year, the absolute number of infections and associated burden remains high. Substantial and systemwide efforts are needed to address peripheral intravenous catheter infection and failure and the sequelae of treatment disruption, increased health costs and poor patient outcomes.

Study Protocol for Two-Steps Parallel Randomized Controlled Trial: Pre-Clinical Usability Tests for a New Double-Chamber Syringe

A new double-chamber syringe (DUO Syringe) was developed for intravenous drug administration and catheter flushing. This study presents a protocol for pre-clinical usability tests to validate the golden prototype of this new device, performed in a high-fidelity simulation lab by nurses. A two-steps parallel randomized controlled trial with two arms was designed (with standard syringes currently used in clinical practice and with the DUO Syringe). After randomization, eligible and consented participants will be requested to perform, individually, intravenous drug administration and flushing, following the arm that has been allocated. The procedure will be video-recorded for posterior analyses. After the completion of the tasks, nurses will be asked to answer a demographic survey, as well as an interview about their qualitative assessment of the device. A final focus group with all participants will also be conducted. Primary outcomes will concern the DUO Syringe's effectiveness, efficiency, and safety, while secondary outcomes will focus on nurses' satisfaction and intention of use. The pre-clinical protocol was defined according to the legal requirements and ISO norms and was reviewed and approved by the Ethics Committee of the Health Sciences Research Unit: Nursing of the Nursing School of Coimbra.

Increased Clinical and Economic Burden Associated With Peripheral Intravenous Catheter-Related Complications: Analysis of a US Hospital Discharge Database

The burden of complications associated with peripheral intravenous use is underevaluated, in part, due to the broad use, inconsistent coding, and lack of mandatory reporting of these devices. This study aimed to analyze the clinical and economic impact of peripheral intravenous–related complications on hospitalized patients. This analysis of Premier Perspective^® Database US hospital discharge records included admissions occurring between July 1, 2013 and June 30, 2015 for pneumonia, chronic obstructive pulmonary disease, myocardial infarction, congestive heart failure, chronic kidney disease, diabetes with complications, and major trauma (hip, spinal, cranial fractures). Admissions were assumed to include a peripheral intravenous. Admissions involving surgery, dialysis, or central venous lines were excluded. Multivariable analyses compared inpatient length of stay, cost, admission to intensive care unit, and discharge status of patients with versus without peripheral intravenous–related complications (bloodstream infection, cellulitis, thrombophlebitis, other infection, or extravasation). Models were conducted separately for congestive heart failure, chronic obstructive pulmonary disease, diabetes with complications, and overall (all 7 diagnoses) and adjusted for demographics, comorbidities, and hospital characteristics. We identified 588 375 qualifying admissions: mean (SD), age 66.1 (20.6) years; 52.4% female; and 95.2% urgent/emergent admissions. Overall, 1.76% of patients (n = 10 354) had peripheral intravenous–related complications. In adjusted analyses between patients with versus without peripheral intravenous complications, the mean (95% confidence interval) inpatient length of stay was 5.9 (5.8-6.0) days versus 3.9 (3.9-3.9) days; mean hospitalization cost was $10 895 ($10 738-$11 052) versus $7009 ($6988-$7031). Patients with complications were less likely to be discharged home versus those without (62.4% [58.6%-66.1%] vs 77.6% [74.6%-80.5%]) and were more likely to have died (3.6% [2.9%-4.2%] vs 0.7% [0.6%-0.9%]). Models restricted to single admitting diagnosis were consistent with overall results. Patients with peripheral intravenous–related complications have longer length of stay, higher costs, and greater risk of death than patients without such complications; this is true across diagnosis groups of interest. Future research should focus on reducing these complications to improve clinical and economic outcomes.

Modelo artesanal para treinamento de acesso vascular periférico

Contexto

O acesso vascular é o procedimento mais comum realizado entre pacientes hospitalizados. Assim, na tentativa de minimizar complicações e aliar conhecimento técnico ao conhecimento teórico, os modelos de simulação são capazes de oferecer um ambiente seguro para profissionais em formação e evitar os dilemas éticos de treinamento direto em pacientes. Com esse objetivo, surgiram diversos manequins de treinamento, mas devido ao seu alto custo eles não são acessíveis a todos, e com frequência os profissionais em formação da área da saúde realizam procedimentos sem que tenham um treinamento prévio.

Objetivo

Desenvolver um modelo de ensino e treinamento de acesso vascular periférico, utilizando um modelo de baixo custo para fins educacionais.

Método

Para reproduzir a via periférica de acesso, utilizou-se um macarrão de polietileno com equipos de infusão, com uma extremidade em fundo cego e a outra conectada a duas bolsas de 500 mL de soro fisiológico acrescido de corante. A bolsa foi instalada em um suporte metálico.

Resultado

O formato sugerido para o modelo apresentou semelhança com a anatomia do antebraço simplificada. O modelo se mostrou prático na punção e, devido à sua extensão, tem-se a possibilidade de puncionar diversas vezes o mesmo modelo, facilitando o treinamento.

Conclusão

O modelo proposto permite o treinamento de acesso vascular periférico, sendo uma alternativa de baixo custo que pode ser utilizada para fins educacionais.
