Relationship between peripheral intravenous catheter Dwell time and the development of phlebitis and infiltration

Developing a Research base for Intravenous Peripheral cannula re-sites (DRIP trial). A randomised controlled trial of hospital in-patients

BACKGROUND

There is currently no high grade evidence on which to base decisions about the frequency of intravenous cannula re-sites.

OBJECTIVE

To assess the safety of changing peripheral venous cannulas when clinically indicated.

DESIGN

Randomised controlled trial.

SETTING

A tertiary referral hospital in Brisbane, Australia.

PARTICIPANTS

Two hundred and six hospitalised patients from surgical, medical and orthopaedic wards.

INTERVENTIONS

Peripheral intravenous cannulas were re-sited only when complications occurred (intervention group) or every 3 days (control group).

MAIN OUTCOME MEASURES

The primary endpoint was any unplanned cannula removal, the secondary outcome was cost.

RESULTS

Forty six patients had unplanned removals in the intervention group compared with 41 in the control group [relative risk 1.12, 95% confidence interval 0.81-1.55 (p=0.286)], a non-significant difference. Total duration of peripheral cannulation was similar in both groups (mean 123.3h in the intervention group and 125.9h in the control group: P=0.82) but significantly more re-sites occurred in the control group (167 in intervention group, 202 in the control group: p=0.022). Cost of cannula replacements in the intervention group was AUD$3,183.62 and in the control group AUD$3,837.56 (p=0.006).

CONCLUSION

Re-siting peripheral venous cannulas when clinically indicated compared with changing them routinely every 3 days does not lead to more complications and reduces costs.

Evidence for elective replacement of peripheral intravenous catheter to prevent thrombophlebitis: a systematic review

AIM

This paper reports a review of the scientific evidence for elective replacement of peripheral intravenous catheters in adults in the absence of any clinical complications, with the aim being to reduce the incidence and severity of thrombophlebitis.

BACKGROUND

The incidence of thrombophlebitis associated with peripheral intravenous catheters has been reported to range from 5.3% to 77.5%. Many factors that increase the risk for thrombophlebitis have been reported, of which time in situ is one. In Sweden, the recommended guideline is elective replacement of peripheral intravenous catheters every 12-24 hours.

METHOD

A systematic literature review was carried out in 2005 using the Cochrane Library, OvidMedline and CINAHL databases and hand searching of reference lists and with keywords catheterization, peripheral, thrombophlebitis and parenteral nutrition. The review included randomized controlled trials of elective replacement of peripheral intravenous catheters in adults. Three reviewers assessed the data found according to predetermined criteria.

FINDING

Three randomized control trials met the inclusion criteria and were retrieved for critical appraisal. The samples in two of the trials included patients requiring total parenteral nutrition. Patients in the third trial were receiving crystalloid and drugs. Time intervals for elective replacement varied. Study quality and relevance were rated as 'medium' in two of the trials and as 'low' in the third trial.

CONCLUSION

Limited scientific evidence suggests that elective replacement of peripheral intravenous catheters reduces the incidence and severity of thrombophlebitis.

A Proactive Approach to Combating Venous Depletion in the Hospital Setting

This study focuses on the effects of infusion nurse specialists on the culture of an institution as it relates to infusion therapy practice. During the 18-month study, data were gathered on the outcomes of the proactive approach instituted by the infusion specialists. Outcomes assessed included phlebitis prevalence, peripherally inserted catheter placements, patient satisfaction scores, and ratio of catheters being placed by interventional radiology to the bedside placements. The study discusses the methods used by the infusion team in an attempt to change the approach to infusion therapy.

Evaluation of a Visual Infusion Phlebitis Scale for Determining Appropriate Discontinuation of Peripheral Intravenous Catheters

Approximately 150 million peripheral intravenous (PIV) catheters are inserted annually in the United States, with a 5% incidence rate of phlebitis as an acceptable benchmark. In 2002, the Centers for Disease Control and Prevention recommended that PIV sites and administration sets be changed at least every 96 hours, yet clinical practice supported that at least 25% of PIV catheters showed no signs of phlebitis at 96 hours' dwell time. This study reports the assessment results of 850 PIV catheters over the indwelling life of the catheter, using the Visual Infusion Phlebitis scale as the measure determining when a PIV should be removed.

Contamination Control in Nursing With Filtration

Filters often are viewed as screens with openings smaller than the particles intended to be removed by a process technically known as direct interception. However, filter manufacturing embraces far more advanced technological approaches, with an evolution toward selective removal of cells or soluble constituents from complex physiologic solutions. An appreciation of filtration development makes it easy to understand how differently manufactured filters with the same claims may not perform identically. This article focuses on the filtration of intravenous solutions and point-of-use hospital water.

Adverse events and complications among patients admitted to hospital in the home directly from the emergency department

INTRODUCTION

The nature and incidence of adverse events and complications among patients admitted from the emergency department to hospital in the home has not been investigated. This study aimed to investigate this problem and make recommendations for prevention strategies.

METHODS

This was an explicit retrospective chart review of patients admitted from the emergency department directly to hospital in the home between 22 February 1995 and 1 September 2000. A data extraction document was designed specifically for the study and used to extract data relating to patient demographics, diagnosis, past medical history and outcome. The outcomes of interest include adverse events, complications and death. An adverse effect is defined as an unintended injury or complication that results in disability, death or prolonged hospital stay and is caused by health care management. These adverse events may occur prior to or during the index admission and may be noted during or after the index admission. A complication is defined as an undesirable outcome that occurs during the management but not causing disability, death or prolonged hospital stay.

RESULTS

Three hundred and fifty-seven patients were enrolled (51.3% male; median age 52 years, range 16-96 years). Fifty-five adverse events were identified: 49 adverse events (89%) were due to management prior to hospital in the home admission and six adverse events (10.9%) were directly attributable to hospital in the home management. This represents a rate of 1.7 adverse events per 100 hospital in the home admissions directly attributable to hospital in the home management. One hundred and eighteen complications were identified. Most complications were easily managed. Thirty-one patients had unplanned re-admissions and two patients died within 28 days of hospital in the home admission.

CONCLUSION

Most patients admitted to hospital in the home from the emergency department were managed successfully. Few adverse events arose from hospital in the home treatment. Complications were common but minor in nature. Strategies for the prevention of phlebitis and constipation are recommended.
