Insertion of peripheral intravenous cannulae in the Emergency Department: factors associated with first-time insertion success

Background We sought to identify the reasons for peripheral intravenous cannulae insertion in the emergency department (ED), and the first-time insertion success rate, along with patient and clinician factors influencing this phenomenon. Methods A prospective cohort study of patients requiring peripheral cannulae insertion in a tertiary ED. Clinical and clinician data were obtained. Results A total 734 peripheral intravenous cannula (PIVC) insertions were included in the study where 460 insertions were analysed. The first-time insertion success incidence was 86%. The antecubital fossa (ACF) site accounted for over 50% of insertions. Multivariate logistic regression modelling to predict first-time insertion success for patient factors found: age <40 versus 80+ years, emaciated versus normal patient size, having a visible or palpable vein/s, and ACF versus forearm insertion site to be statistically significant. Statistically significant clinician factors predicting success were: higher number of prior cannulation procedures performed, and increased clinician perception of the likelihood of a successful insertion. When patient and clinician factors were combined in a logistic regression model, emaciated versus normal, visible vein/s, ACF versus forearm site, higher number of prior PIVC procedures performed and increased clinician perceived likelihood of success were statistically associated with first-time insertion success. Conclusions Peripheral intravenous cannulation insertion success could be improved if performed by clinicians with greater procedural experience and increased perception of the likelihood of success. Some patient factors predict cannulation success: ‘normal’ body weight, visible vein/s and cubital fossa placement; venepuncture may be a cheaper alternative for others if intravenous therapy is not imperative.

Predicting and preventing peripheral intravenous cannula insertion failure in the emergency department: Clinician ‘gestalt’ wins again

Failed attempts at peripheral i.v. cannula (PIVC) insertion in the ED are common. The psychological, physical and economic impact of these failures is significant. We sought to explore whether clinicians of differing experience levels can predict their own likelihood (clinician ‘gestalt’) of first‐time cannula insertion success on any given patient.

Development of a clinical prediction rule to improve peripheral intravenous cannulae first attempt success in the emergency department and reduce post insertion failure rates: the Vascular Access Decisions in the Emergency Room (VADER) study protocol.

Introduction Peripheral intravenous cannula (PIVC) insertion is one of the most common clinical interventions performed in emergency care worldwide. However, factors associated with successful PIVC placement and maintenance are not well understood. This study seeks to determine the predictors of first time PIVC insertion success in emergency department (ED) and identify the rationale for removal of the ED inserted PIVC in patients admitted to the hospital ward. Reducing failed insertion attempts and improving peripheral intravenous cannulation practice could lead to better staff and patient experiences, as well as improving hospital efficiency. Methods and analysis We propose an observational cohort study of PIVC insertions in a patient population presenting to ED, with follow-up observation of the PIVC in subsequent admissions to the hospital ward. We will collect specific PIVC observational data such as; clinician factors, patient factors, device information and clinical practice variables. Trained researchers will gather ED PIVC insertion data to identify predictors of insertion success. In those admitted from the ED, we will determine the dwell time of the ED-inserted PIVC. Multivariate regression analyses will be used to identify factors associated with insertions success and PIVC failure and standard statistical validation techniques will be used to create and assess the effectiveness of a clinical predication rule. Ethics and dissemination The findings of our study will provide new evidence to improve insertion success rates in the ED setting and identify strategies to reduce premature device failure for patients admitted to hospital wards. Results will unravel a complexity of factors that contribute to unsuccessful PIVC attempts such as patient and clinician factors along with the products, technologies and infusates used.

A Time and Motion Study of Peripheral Venous Catheter Flushing Practice Using Manually Prepared and Prefilled Flush Syringes

Peripheral venous catheters (PVCs) are the simplest and most frequently used method for drug, fluid, and blood product administration in the hospital setting. It is estimated that up to 90% of patients in acute care hospitals require a PVC; however, PVCs are associated with inherent complications, which can be mechanical or infectious. There have been a range of strategies to prevent or reduce PVC-related complications that include optimizing patency through the use of flushing. Little is known about the current status of flushing practice. This observational study quantified preparation and administration time and identified adherence to principles of Aseptic Non-Touch Technique and organizational protocol on PVC flushing by using both manually prepared and prefilled syringes.

Nursing and midwifery practice for maintenance of vascular access device patency. A cross-sectional survey

BACKGROUND Up to 85% of hospital in-patients will require some form of vascular access device to deliver essential fluids, drug therapy, nutrition and blood products, or facilitate sampling. The failure rate of these devices is unacceptably high, with 20-69% of peripheral intravenous catheters and 15-66% of central venous catheters failing due to occlusion, depending on the device, setting and population. A range of strategies have been developed to maintain device patency, including intermittent flushing. However, there is limited evidence informing flushing practice and little is known about the current flushing practices. OBJECTIVE The aim of the study was to improve our understanding of current flushing practices for vascular access devices through a survey of practice. METHOD A cross-sectional survey of nurses and midwives working in the State of Queensland, Australia was conducted using a 25-item electronic survey that was distributed via the local union membership database. RESULTS A total of 1178 surveys were completed and analysed, with n=1068 reporting peripheral device flushing and n=584 reporting central device flushing. The majority of respondents were registered nurses (55%) caring for adult patients (63%). A large proportion of respondents (72% for peripheral, 742/1028; 80% for central, 451/566) were aware of their facilitys policy for vascular access device flushing. Most nurses reported using sodium chloride 0.9% for flushing both peripheral (96%, 987/1028) and central devices (75%, 423/566). Some concentration of heparin saline was used by 25% of those flushing central devices. A 10-mL syringe was used by most respondents for flushing; however, 24% of respondents used smaller syringes in the peripheral device group. Use of prefilled syringes (either commercially prepared sterile or prefilled in the workplace) was limited to 10% and 11% respectively for each group. The frequency of flushing varied widely, with the most common response being pro re nata (23% peripheral and 21% central), or 6 hourly (23% peripheral and 22% central). Approximately half of respondents stated that there was no medical order or documentation for either peripheral or central device flushing. CONCLUSIONS Flushing practices for vascular access device flushing appear to vary widely. Specific areas of practice that warrant further investigation include questions about the efficacy of heparin for central device flushing, increasing adherence to the recommended 10mL diameter syringe use, increased use of prefilled flush syringes, identifying and standardising optimal volumes and frequency of flushing, and improving documentation of flush orders and administration.

Implementing music therapy on an adolescent inpatient unit: a mixed-methods evaluation of acceptability, experience of participation and perceived impact

Objective: We aimed to assess the feasibility of delivering a music therapy program on adolescent psychiatric wards. Method: We undertook a mixed-methods evaluation of a pilot program. Various active and receptive techniques were employed in group music therapy sessions delivered as part of a structured clinical program. Data collected in interviews with participants and staff and feedback questionnaires were thematically and descriptively analysed and triangulated. Results: Data from 62 questionnaires returned by 43 patients who took part in 16 music therapy sessions, and seven staff, evidenced strong support for music therapy. Patients typically reported experiencing sessions as relaxing, comforting, uplifting, and empowering; >90% would participate by choice and use music therapeutically in the future. Staff endorsed music therapy as valuable therapeutically, reporting that patients engaged enthusiastically and identified sessions as improving their own moods and ward milieu. Conclusions: Integration of music therapy in inpatient treatment of adolescents is feasible and acceptable, and is valued by staff and patients as a complement to ‘talking therapies’. Participation is enjoyed and associated with outcomes including improvement in mood, expression of feelings and social engagement consistent with recovery.

Use of Short Peripheral Intravenous Catheters: Characteristics, Management, and Outcomes Worldwide

BACKGROUND Peripheral intravenous catheter (PIVC) use in health care is common worldwide. Failure of PIVCs is also common, resulting in premature removal and replacement. OBJECTIVE To investigate the characteristics, management practices, and outcomes of PIVCs internationally. DESIGN SETTING/PATIENTS Cross-sectional study. Hospitalized patients from rural, regional, and metropolitan areas internationally. MEASUREMENTS Hospital, device, and inserter characteristics were collected along with assessment of the catheter insertion site. PIVC use in different geographic regions was compared. RESULTS We reviewed 40,620 PIVCs in 51 countries. PIVCs were used primarily for intravenous medication (n = 28,571, 70%) and predominantly inserted in general wards (n = 22,167, 55%). Two-thirds of all devices were placed in non-recommended sites such as the hand, wrist, or antecubital veins. Nurses inserted most PIVCs (n = 28,575, 71%); although there was wide regional variation (26% to 97%). The prevalence of iIn this study, we found that many PIVCs were placed in areas of flexion, were symptomatic or idle, had suboptimal dressings, or lacked adequate documentation. This suggests inconsistency between recommended management guidelines for PIVCs and current practice.dle PIVCs was 14% (n = 5,796). Overall, 10% (n = 4,204) of PIVCs were painful to the patient or otherwise symptomatic of phlebitis; a further 10% (n = 3,879) had signs of PIVC malfunction; and 21% of PIVC dressings were suboptimal (n = 8,507). Over one-third of PIVCs (n = 14,787, 36%) had no documented daily site assessment and half (n = 19,768, 49%) had no documented date and time of insertion. CONCLUSIONS In this study, we found that many PIVCs were placed in areas of flexion, were symptomatic or idle, had suboptimal dressings, or lacked adequate documentation. This suggests inconsistency between recommended management guidelines for PIVCs and current practice.

Reasons for Removal of Emergency Department–Inserted Peripheral Intravenous Cannulae in Admitted Patients: A Retrospective Medical Chart Audit in Australia

It has been reported that the peripheral intravenous cannula (PIVC) is the first choice of vascular access device for patient treatment in the emergency department (ED). The number of PIVC insertions in our Australian ED is more than 35,000 per year. Concern arises when ED-inserted PIVCs are used exclusively for blood sampling because this may lead to unused PIVCs being left in situ after patients are transferred to the ward, increasing risk of infection. The rate of unused or idle PIVCs inserted in the ED has been reported at 45%-50%. PIVC insertions in the ED have been identified as a cause for phlebitis and bacteremia, leading to their premature failure. Analysis of 5 years of prospective data from 2 hospitals in Australia found a high incidence of catheter-related Staphylococcus aureus bloodstream infections with 39.6% of such infections associated with PIVCs inserted in the ED. As a result, routine PIVC replacement should be considered after 24 hours for PIVCs inserted under emergent conditions 6 and after 96 hours for those inserted under nonemergent conditions. These worrying statistics prompted the design of the current study that was performed to investigate how and why PIVCs are used in the ED, and during the subsequent hospital admission, as well as the documented rationale for removal of ED-inserted PIVCs by ward staff. To our knowledge, there is no prior study investigating this phenomenon.

Foam dressings for treating pressure injuries in patients of any age in any care setting: An abridged Cochrane Systematic Review

BACKGROUND Pressure injuries are localised areas of injury to the skin and/or underlying tissues. OBJECTIVES To assess foam dressings compared to other dressings in healing pressure injuries. DESIGN Systematic review and meta-analysis DATA SOURCES: The review team searched: the Cochrane Wounds Specialised Register; the Cochrane Central Register of Controlled Trials; Ovid MEDLINE; Ovid Embase; EBSCO CINAHL Plus and the NHS Economic Evaluation Database. Authors also searched clinical trials registries and scanned reference lists for reviews, meta-analyses and health technology reports. No restrictions were applied to language, publication date or study setting. STUDY ELIGIBILITY CRITERIA Published or unpublished randomised controlled trials and cluster- randomised controlled trials that examined the clinical or cost effectiveness of foam dressings for healing pressure injuries. PARTICIPANTS Patients of any age with a pressure injury of Stage II or above in any care setting. INTERVENTIONS Use of any foam wound dressing for treating Stage II pressure injuries or above. STUDY APPRAISAL AND SYNTHESIS METHODS Full-text were assessed for eligibility using a priori criteria by two authors. Risk of bias was assessed using the Grading of Recommendations, Assessment, Development and Evaluation criteria, and Consolidated Health Economic Evaluation Reporting Standards. Risk ratio and mean difference with 95% confidence intervals were used to measure the effect. The review team used Review Manager 5 to enter narrative and qualitative data of included studies. RESULTS Authors found nine studies published between 1994 and 2016 involving 483 participants with pressure injuries at Stage II or above. Included studies compared foam dressings with other types of dressings. However, it was unclear if the foam dressing affected healing (RR 1.00, 95% CI 0.78-1.28), time to complete healing (MD 5.67 days 95% CI-4.03-15.37), adverse events (RR 0.33, 95% CI 0.01-7.65), or reduction in pressure injury size (MD 0.30 cm2 per day, 95% CI -0.15 to 0.75), as the certainty of the evidence was very low. LIMITATIONS Using the Grading of Recommendations, Assessment, Development and Evaluation criteria, the certainty and completeness of evidence was low to very low, making it difficult to draw comparisons between foam and other dressings. CONCLUSIONS AND IMPLICATIONS It is uncertain whether foam dressings are more clinically effective, more acceptable to users, or more cost effective compared to alternative dressings in treating pressure injuries.
