Incidence, severity and risk factors of peripheral intravenous cannula-induced complications: An observational prospective study.
To determine the incidence, severity and risk factors of peripheral intravenous cannula-induced complications.
Peripheral venous cannulation in hospitalised patients may cause complications such as phlebitis, infiltration, occlusion and dislodgement. A review of the literature reveals the discrepancy in their incidence and identification of a wide range of risk factors, whereas the data on the occurrence and degree of severity are insufficient.
An observational prospective study.
The study observed 1,428 peripheral intravenous cannula insertion among 368 adult patients hospitalised at the tertiary healthcare clinics. The data collection and analysis included patients' medical data and the data related to each cannula (including placement, monitoring and the reasons for removal), as well as the data on the type of administered medications and solutions. Reporting of this research adheres to the STROBE guidelines.
Phlebitis ranked first among complications with occurrence of 44%, followed by infiltration of 16.3%, while the incidence of occlusion and catheter dislodgement was 7.6% and 5.6%, respectively. In assessing the occurrence of phlebitis, multivariate analysis highlighted the presence of comorbidity, current infection, catheter size, time in situ and the number of administrations of infusion solutions associated with risk, whereas 20-gauge catheter, two or more attempts at cannulation and administration of a high-risk solutions during the first day have been singled out with regard to infiltration. As for the severity, the most common was medium stage of phlebitis, whereas grade 2 was most commonly observed for infiltration.
The incidence of infiltration, occlusion and dislodgment is almost congruent with the average incidence of previous studies. However, the incidence and degree of severity associated with the occurrence of phlebitis were significantly higher.
The results of the study draw attention to vulnerable groups of patients, cannula-specific and pharmacological risk factors for the development of peripheral intravenous cannula-induced complications.

Peripheral intravenous catheter failure: A secondary analysis of risks from 11,830 catheters.
Peripheral intravenous catheters are an essential medical device which are prone to complications and failure.
Identify patient, provider and device risk factors associated with all-cause peripheral intravenous catheter failure as well as individual complications: phlebitis, infiltration/occlusion, and dislodgement to improve patient outcomes.
Secondary analysis of twelve prospective studies performed between 2008 and 2020.
Australian metropolitan and regional hospitals including one paediatric hospital.
Participants were from medical, surgical, haematology, and oncology units.
Multilevel mixed-effects parametric survival regression was used to identify factors associated with all-cause peripheral intravenous catheter failure, phlebitis, occlusion/infiltration, and dislodgement. We studied patient (e.g., age, gender), device (e.g., gauge), and provider (e.g., inserting clinician) variables. Stepwise regression involved clinically and p<0.20 significant variables entered into the multivariable model. Results were expressed as hazard ratios (HRs) and 95% confidence intervals (CI); p<0.01 was considered statistically significant.
Of 11,830 peripheral intravenous catheters (8,200 participants) failure occurred in 36% (n = 4,263). Occlusion/infiltration incidence was 23% (n = 2,767), phlebitis 12% (n = 1,421), and dislodgement 7% (n = 779) of catheters. Patient factors significantly associated with failure and complications were: female gender (phlebitis; (HR 1.98, 95% CI 1.72-2.27), (infiltration/occlusion; HR 1.45, 95% CI 1.33-1.58), (failure; HR 1.36, 95% CI 1.26-1.46); and each year increase in age (phlebitis; 0.99 HR, 95% CI 0.98-0.99), (failure; 0.99 HR, 95% CI 0.99-0.99). The strongest provider risk factor was intravenous antibiotics (infiltration/occlusion; HR 1.40, 95% CI 1.27-1.53), (phlebitis; HR 1.36, 95% CI 1.18-1.56), (failure; HR 1.26, 95% CI 1.17-1.36). Catheters inserted by vascular access teams were less likely to dislodge (HR 0.53, 95% CI 0.42-0.67). Device risk factors most associated with all-cause failure were wrist/hand (HR 1.34, 95% CI 1.23-1.46), antecubital fossa peripheral intravenous catheters (HR 1.29, 95% CI 1.16-1.44) and 22/24 gauge (HR 1.27, 95% CI 1.12-1.45) catheters.
Factors identified, including the protective aspect of vascular access team insertion, and high catheter failure associated with intravenous antibiotic administration, will allow targeted updates of peripheral intravenous catheter guidelines and models of care.

Routine replacement versus replacement as clinical indicated of peripheral intravenous catheters: A multisite randomised controlled trial.
To compare the safety of replacing peripheral intravenous catheter as clinically indicated versus routine replacement on patient outcomes in the Chinese context.
Some evidence from developed countries recommend replacing peripheral intravenous catheter as clinically indicated; however, there is limited evidence from developing countries.
A multisite randomised controlled trial.
The 3050 participants from three hospitals in China were randomly assigned to clinically indicated or routine replacement groups. Patients in the clinically indicated group had the catheters kept in situ until any of the following clinical signs appeared: phlebitis, infiltration, occlusion, displacement, local infection and diagnosed catheter-related bloodstream infection. Patients in the routine replacement group had their peripheral intravenous catheters replaced every 96 hours. The outcomes of phlebitis, infiltration, occlusion, displacement; catheter-related bloodstream infection, all-cause bloodstream infection, and local infection were compared. CONSORT checklist was used to guide the reporting of this RCT.
The risk of phlebitis, phlebitis per 1000 catheter days, occlusion, dislodgement, all bloodstream infections, local infection and mortality between the two groups were not significantly different. The risk of infiltration was increased in the clinically indicated group (HR 1.29). There was no catheter-related bloodstream infection reported in either group. Patients' first peripheral intravenous catheter dwelling time and cumulative indwelling time of all peripheral intravenous catheters in the clinically indicated group were significantly longer than the routine replacement group. There was no statistical significant difference in survival times from phlebitis between the two groups.
In the Chinese context, removing peripheral catheters as clinical indicated did not increase the risk of phlebitis, occlusion, catheter displacement and catheter infection; however, there was an increased infiltration incidence.
In developing countries, removing peripheral catheters as clinical indicated is feasible, but more frequent observations of infiltration are highly recommended.
