Soft tissue infections related to peripheral intravenous catheters in hospitalised patients: a case–control study

The Outcome of Moderate-to-Severe Complications Related to Peripheral Intravenous Devices at Upper Limb

Background: Intravenous access is very crucial in administration of fluids, medications and nutrition. Almost all inpatients will require it and the simplest and quickest access is peripheral with the preferred sites being either dorsum hand, radial wrist or forearm. It has its complications, of which most are avoidable. Literature has emphasised the complications and reported on preventive measures but lacks the sequelae of the complications related to peripheral intravenous devices (PIVD). We report on the sequelae of moderate-to-severe complications of these patients. Methods: Thirty-three patients had moderate-to-severe complications related to PIVD in a tertiary centre from January 2017 to December 2017. All data were obtained from electronic medical report (EMR). Results: Majority had extravasation (45.5%) and abscess (39.4%), whereas two patients had thrombophlebitis (6.1%) and three patients developed necrotising fasciitis (9.1%). All patients with abscess and necrotising fasciitis underwent surgical intervention (n = 16); four patients had multiple debridements. All infections were treated with empirical antibiotics and changed after culture results were obtained. Seven patients had sepsis/bacteraemia wherein two of them passed away. A total of 31 patients were discharged. Two patients had secondary suturing of the wound, one had split-thickness skin grafting (SSG) coverage and the others had daily dressing until the wound healed by secondary intention. Conclusions: PIVD-related complications can be debilitating and may occur despite strict preventive measures. Early clinical diagnosis and prompt treatment of these complications can decrease its morbidity. Level of Evidence: Level IV (Prognostic).

Septic pulmonary emboli as a complication of peripheral venous cannula insertion

Septic pulmonary emboli can occur as a complication of many diseases, most common being right sided infective endocarditis. Septic emboli through a peripheral venous cannula are rarely reported in literature though central venous catheter is commonly implicated. We describe a case of widespread cellulitis and septic pulmonary emboli as a complication of peripheral venous cannulation.

Epidemiology of intravenous fluid use for headache treatment: Findings from the National Hospital Ambulatory Medical Care Survey

BACKGROUND

Headache is one of the most common reasons for patients to seek care in emergency departments. While the administration of intravenous fluids is frequently recommended for emergency department patients with migraine, the epidemiology of the use of this intervention is unknown.

OBJECTIVES

To describe the epidemiology of intravenous fluid use in emergency department patients with headache.

METHODS

This retrospective study utilized the 2011 US National Hospital Ambulatory Medical Survey, a multi-stage weighted survey providing nationally representative estimates of ED visits. Patients with chief complaints of non-traumatic headache or migraine headache were included. We determined the frequency of intravenous fluid administration among patients presenting with headache, and among specific subgroups including those with migraine headache.

RESULTS

There were 1251 sample cases representing 5,981,000 visits for a chief complaint of headache. Intravenous fluids were administered at 40% (95% CI 35-44%) of these visits. Among the 222 migraine cases, 47% (95% CI 39-56%) received fluids. Fluids were commonly administered regardless of pain severity, and fluid administration was not significantly associated with pain severity among patients diagnosed with migraine (p=0.39). After adjusting for patient characteristics, ED visit duration remained greater for patients receiving fluids than for those who did not among both patients with a headache complaint and among those with a diagnosis of migraine headache.

CONCLUSIONS

Despite a lack of efficacy data, patients treated in United States EDs for headache frequently receive IV fluids. Studies are needed to determine the efficacy of this basic treatment intervention.

Peripheral Venous Catheter-Related Adverse Events: Evaluation from a Multicentre Epidemiological Study in France (the CATHEVAL Project)

Introduction

Peripheral venous catheters (PVC) are medical devices most frequently used during hospital care. Although the frequency of specific PVC-related adverse events (PVCAEs) has been reported, the global risk related to the insertion of this device is poorly estimated. The aim of this study is to determine the incidence of PVCAEs during the indwell time, after catheter removal, and to identify practice-mirroring risk factors.

Methods

A prospective observational study was conducted as a part of a research project, called CATHEVAL, in one surgery ward and four medicine wards from three public general tertiary care hospitals in Northern France that were invited to participate between June-2013 and June-2014. Each participating ward included during a two-month study period all patients older than 15 years carrying a PVC. All inserted PVCs were monitored from insertion of PVC to up to 48 hours after removal. Monitored data included several practice-mirroring items, as well as the occurrence of at least one PVCAE. A multivariate Cox proportional hazard model, based on a marginal risk approach, was used to identify factors associated with the occurrence of at least one PVCAE.

Results

Data were analysed for 815 PVCs (1964 PVC-days) in 573 patients. The incidence of PVCAE was 52.3/100 PVCs (21.9/100 PVC-days). PVCAEs were mainly clinical: phlebitis (20.1/100 PVCs), haematoma (17.7/100 PVCs) and liquid/blood escape (13.1/100 PVCs). Infections accounted for only 0.4/100 PVCs. The most frequent mechanical PVCAEs, was obstruction/occlusion of PVC (12.4/100 PVCs). The incidence of post-removal PVCAEs was 21.7/100 PVCs. Unstable PVC and unclean dressing were the two main risk factors.

Conclusion

Limitation of breaches in healthcare quality including post-removal monitoring should be reinforced to prevent PVC-related adverse events in hospital settings.

Risk factors for central line-associated bloodstream infections in the era of best practice

BACKGROUND

Best clinical practice aims to eliminate central line-associated blood stream infections (CLABSIs). However, CLABSIs still occur. This study's aim was to identify risk factors for CLABSI in the era of best practice.

METHODS

Critically ill surgical patients admitted over 2 years to the intensive care unit (ICU) for ≥ 4 days were studied. Patients with CLABSI as cause for ICU admission were excluded. Patients who developed CLABSI (National Healthcare Safety Network definition) were compared with those who did not. Hand hygiene, maximal sterile barriers, chlorhexidine scrub, avoidance of femoral vein, and proper maintenance were emphasized. Variables collected included demographics, diagnosis, and severity of illness using the Acute Physiology and Chronic Health Evaluation (APACHE) IV database and the hospital central data repository.

RESULTS

Of 961 patients studied, 51 patients (5.2%) developed 59 CLABSIs. Mean time from ICU admission to CLABSI was 26 days ± 26 days. The CLABSI group was more likely to be male (odds ratio [OR] 1.93, 95% confidence interval [CI] 1.02-3.68), more critically ill on ICU admission (APACHE IV score 85.2 ± 21.9 vs. 65.6 ± 23.2, p < 0.01), more likely admitted to the emergency surgery service (OR 1.92, 95% CI 1.02-3.61), and had an association with reopening of recent laparotomy (OR 2.08, 95% CI 1.10-3.94).

CONCLUSION

In the era of best practice, patients who develop CLABSI are clinically distinct from those who do not develop CLABSI. These CLABSIs may be due to deficiencies of the CLABSI definition or represent patient populations requiring enhanced prevention techniques.
