Running Header: IMPLICATIONS FOR PIVC DISCONTINUATION Implications for Clinically Indicated Discontinuation of Peripheral Intravenous Catheters Andrew Bierman Azusa Pacific University Diana Amaya Rodriguez, PhD, MS, CNS, RN GNRS 507 – Scientific Writing April 4th, 2015 1 IMPLICATIONS FOR PIVC DISCONTINUATION 2 The most recent research of peripheral intravenous catheter (PIVC) discontinuation is based on clinical indication rather than on routine. The purpose of this literature review is to provide a detailed analysis and discussion of PIVC discontinuation intervention research. This literature review will incorporate the most pertinent research that has addressed PIVC discontinuing interventions, specifically when clinically indicated. Background CDC recommendations support the removal of peripheral intravenous catheters (PIVCs) on a routine schedule. The CDC recommendations were based upon three studies completed between the years of 1983 and 1998 (CDC, 2011). Although the incidence of phlebitis and blood stream infections associated with PIVCs was usually low, serious complications can lead to death due to the frequency at which such catheters are used (CDC, 2011). Phlebitis is identified as the leading cause of sepsis and infection associated with PIVC usage (Ho & Cheung, 2012). Discontinuation of the PIVC based on clinical indications rather than routine can allow for longer PIVC indwell times without an increase in phlebitis and infection. This would lead to decreased PIVC insertions, discomfort, and pain when PIVC’s are used throughout the patient's hospital stay. In hospitalized adult patients with Peripheral Intravenous Catheters (PIVCs) that are used throughout the patients' hospital stay, does PIVC discontinuation when clinically indicated extend PIVC indwell time with no increase in incidences of phlebitis, versus PIVC discontinuation based on routine schedule? IMPLICATIONS FOR PIVC DISCONTINUATION 3 Current Guidelines and their Challenges Each year, millions of peripheral intravenous catheters are discontinued 72-96 hours after insertion (Rickard, Webster et al., 2012). Early studies showed a correlation between indwell times and incidence of phlebitis (Rickard, McCann et al., 2014). As a result, the CDC recommend that PIVCs be discontinued based upon a routine schedule in order to decrease the incidence of phlebitis (CDC, 2011). CDC recommendations are adopted by hospitals across the world, however, research is finding no clinical preferences for discontinuing PIVCs based on routine against discontinuing PIVCs when clinically indicated (Ho & Cheung, 2012). Furthermore, Clemen et al. (2012) pointed out that, of the articles utilized by the CDC to support their recommendation, all but one article focused on the use of central venous catheters (CVCs) instead of PIVCs. Van Donk, Rickard, Doolan, and McGrail (2009) concluded that routine discontinuation of PIVCs is only more beneficial than clinically indicated discontinuation when the discontinuation occurs every 24 hours. However, the study highlighted how unfeasible that would be, as the cost, patient discomfort, and time expenditure by the nurses would dramatically increase. It is clear from these varied indications that a review of current guidelines is necessary. Clinically Indicated Discontinuation The need for the CDC to review the standards for discontinuing PIVCs is apparent. While currently, PIVCs are being discontinued on a routine schedule, clinically indicated discontinuation focuses on removing the catheter only when necessary. Discontinuing PIVCs when clinically indicated can allow for longer indwell times (Rickard & Webster et al., 2012). These longer indwell times will lead to less insertions of PIVCs, less catheters used, cost savings to the hospital and patient, and less discomfort for the patient (Gonzalez Lopez et al., 2014). It is IMPLICATIONS FOR PIVC DISCONTINUATION 4 important to mention that the most current CDC guidelines released in 2011 do mention PIVC discontinuation when clinically indicated twice in their guideline recommendations. The CDC recommends clinically indicated discontinuation of PIVCs for pediatric patients (CDC, 2011). For adults, they consider PIVC discontinuation by clinical indication as “unresolved,” a term Rickard and Webster et al. (2012) defines as needing more research. Ho and Cheung (2012) highlight this as nothing more than confusing for healthcare workers as the CDC recommends an intervention while at the same time claiming that not enough research has been done on that very same intervention. Current Research Of the ten articles discussed within this literature review, five research articles relate directly to the relationship between incidence of phlebitis and discontinuing a PIVC based on clinical indications rather than by routine (Benbow, 2009, Gonzalez Lopez, 2012, Rickard, 2010, Rickard & Webster 2012, Van Donk, 2009). Other research compared open and closed PIVC systems being discontinued when clinically indicated and others evaluated nurses' perceptions and decision making processes for clinically indicated discontinuation of PIVCs. Overall, the research trends implicate discontinuation of PIVCs when clinically indicated rather than by a routine. Variables Though overall findings show a consensus recommendation for clinical indication, individual variables play a vital role in determining the findings. Exploring these variables can further evidence the factors recommending this consensus. Trends found within the research focused on aspects of PIVC usage such as incidence if phlebitis and indwell times. Additional IMPLICATIONS FOR PIVC DISCONTINUATION 5 considerations such as nursing assessment and current practices and technology of PIVCs were also briefly discussed by a few of the research articles, and can contribute to the consensus. Phlebitis. Phlebitis is an irritation of the vein that causes pain, erythema, swelling, and heat (Rickard, McCann, Munnings, and McGrail, 2010). Phlebitis was the main variable used to establish the CDC recommendation, with the purpose to decrease its incidence. Though, not all of the research studies individually define phlebitis, the previously discussed definition closely matches the CDC definition. Within the research studies, phlebitis is used as the primary determinate for catheter failure. The goal of the research was to show that incidence of phlebitis will not increase when discontinuing the PIVC only when clinically indicated, even if indwell times prolong. The Rickard et al. (2012) study found that 7% of PIVCs failed due to phlebitis in both the routine and clinically indicated sample populations, while accounting for longer indwell times with the clinically indicated group. Benbow (2009) found that only 4% of PIVCs failed due to phlebitis in the clinically indicated sample group, while 3% of PIVCs failed due to phlebitis in the routine replacement group. Though the routine replacement group had a 1% decrease in incidence of phlebitis, Benbow (2009) consider that to be statistically insignificant. The other research articles (Rickard, 2010, Rickard & Webster 2012, Van Donk, 2009) that compare routine and clinically indicated PIVC discontinuation had similar findings. Indwell times. Phlebitis and other catheter related complications are directly associated with catheter indwell times (Gonzalez Lopes et al., 2013). Indwell times refer to the duration for which the PIVC catheter remains inserted into the patients vessel. According to research associated with the CDC guidelines, as catheter indwell times increase, so to do the incidence of phlebitis (DHHS, 2011). Therefore, the CDC recommended indwell times of no greater than 96 IMPLICATIONS FOR PIVC DISCONTINUATION 6 hours. Other research, however, found that indwell times up to 137 hours can be reached without any statistically significant increase in incidence of phlebitis. In the study by Rickard et al. (2012), clinically indicated discontinuation allowed for average indwell times of 99 hours without any increase in phlebitis cases. Furthermore, the study conducted by Van Donk, Rickard, McGrail, and Doolan (2009) found that PIVC indwell times can increase to 108 hours without increase in incidence of phlebitis when discontinuing the PIVC based on clinical indication. Gonzalez Lopez et al. (2012) took the study a step further and found that by utilizing closed PIVC systems, indwell times can increase to 137 hours when discontinuing only when indicated. Increasing indwell times can have secondary benefits that include improvements in patient comfort and cost savings to both the hospital and the patient (Lee et al., 2009). Gonzalez Lopez (2012) found there to be a nearly $100,000.00 in cost savings overall, when utilizing closed PIVC systems for up to 137 hours. This cost savings is a shared finding in most of the other research articles due to increased indwell times and less PIVC insertions. Clemen et al. (2012) concluded immediate benefits would be that the patients pain and discomfort levels would decrease due to less PIVC insertions, which would also lend to time savings for the nurses not having to insert more PIVCs. Additional considerations. While clinically indicated PIVC discontinuation was consistently recommended as a superior method for PIVC discontinuation, other factors and variables may also play important roles in efficacy. Lee et al. (2009) indicate that the utilization of well-trained IV specialist may be the key to success. Though IV specialist may be an important factor in the prevention of phlebitis, Benbow (2009) made a point to highlight the importance of regular nursing assessments of the PIVC sites when changing to a non-routine IMPLICATIONS FOR PIVC DISCONTINUATION 7 approach for discontinuation, especially in the absence of IV specialists. Though IV specialist would be ideal for any PIVC usage, the reality is that most hospitals do not have the benefit of these specialists at all times. The importance of nurses making clinical decisions about PIVC usage and whether to keep the PIVC indwelling for longer periods of time, is paramount (Palese et al., 2010). Education and comprehensive training is necessary to ensure the most informed healthcare professionals, and it is essential to equip them with the tools to adequately care for PIVCs (Ho & Cheung, 2014). Another consideration for PIVC discontinuation is the advancement of technology. Since the 1998 research, there have been PIVC technology advancements. Rickard et al. (2012) highlighted that the most current PIVCs are made with low-irritant materials that can allow for longer indwell times without adverse reactions. Gonzalez Lopez (2013) compared closed PIVC systems in their research and have identified that these systems have lower rates of microbial contamination. With the inception of new materials and new PIVC systems, indwell times can increase without the incidence of phlebitis also increasing. Findings, Strengths, and Limitations. The most significant strengths found in the research is the overwhelming unanimity and consensus of the findings. Of the research that compared the incidence of catheter failure, all found no statistically significant difference in incidences of phlebitis between routine replacement of PIVCs and clinically indicated replacement of PIVCs. Of the research comparing indwell times between the two interventions, all research articles found an increase in PIVC indwell times. IMPLICATIONS FOR PIVC DISCONTINUATION 8 Though the research articles demonstrate strong evidence towards affirming clinically indicated replacement of PIVCs, they don’t go without limitations in the research. Sample size and location diversity were limiting factors in a few of the research studies. The Rickard, McCann, Munnings, and McGrail (2010) research had only 362 participants from one regional hospital in Australia. With the Pales et al. (2011) study only 269 PIVCs were observed during the study. Data accuracy can decline with a low sampling census and poor variability in the sampling population. The CDC indicates in their guidelines that more research is necessary before clinically indicated discontinuation of PIVCs is adopted as a recommendation for adults. Further research to increase the accuracy of the data, is essential especially when working with interventions that can harm the patient. Conclusion Discontinuing a PIVC based on a routine schedule might seem like the best way to decrease infection in patients, however, the research shows that this may not be the case. The most current research seems to find no increase in incidence of phlebitis when PIVC indwell times exceed routine replacement timeframes. Successful implementation of standards based on clinical indication will rely heavily on comprehensive nursing assessments of the PIVC site, something nurses already do now Replacing PIVCs when clinically indicated can prolong the life of PIVCs without an increase in incidence of phlebitis. This can lead to less PIVC insertions, less patient discomfort, and less costly medical expenditures. Overall, the research supports clinically indicated discontinuation versus routine. It is clear there are benefits to clinically indicated discontinuation of PIVCs over routine replacement, and is recommended that the CDC seriously evaluate current research for adoption as a recommendation into their guidelines. IMPLICATIONS FOR PIVC DISCONTINUATION 9 Clinical Implications Clinically indicated discontinuation of Peripheral Intravenous Catheters (PIVCs) provides benefits beyond just extending indwell times. The key findings of the research implicate the need for change and create a framework for which a plan for change can be built. The purpose of this segment is to create that plan for change along with evaluating the question, in hospitalized adult patients with Peripheral Intravenous Catheters (PIVCs) that are used throughout the patients' hospital stay, does PIVC discontinuation when clinically indicated extend PIVC indwell time with no increase in incidences of phlebitis, versus PIVC discontinuation based on routine schedule? Key findings and Research Grading PIVC systems are currently discontinued based upon CDC guidelines which recommends discontinuation every 72-96 hours. These guidelines were established to decrease incidence of phlebitis and infection. The most current research finds that the healthcare system and its patients can benefit from discontinuing a PIVC only when clinically indicated (Rickard et al., 2012). Current research finds that clinically indicated discontinuation of PIVCs can be implemented without significant increases in the incidence of phlebitis compared to routine replacement (Benbow, 2009, Rickard and McCann et al. 2010, Rickard et al. 2012, Van Donk et al., 2009). Clinically indicated discontinuation can increase PIVC indwell times (Gonzalez Lopez et al, 2014, Rickard and McCann et al. 2010, Rickard et al. 2012, Van Donk et al., 2009). The usage of closed PIVC systems versus open systems, has been found to extend indwell times to 137 hours when clinically indicated (Gonzalez Lopez et al, 2014). The extension of PIVC IMPLICATIONS FOR PIVC DISCONTINUATION 10 indwell times can lead to a decrease in the number used on patients. Less PIVC insertion may decrease the incidence of patient anxiety and discomfort associated with their use. For all research, the Melnyk and Fineout-Overholt scale was used to grade the research quality. Benbow (2009), Gonzalez Lopez et al. (2014), Rickard and McCann et al. (2010), Rickard et al. (2012), Van Donk et al. (2009) were all graded as level two studies, as their study designs were all randomized controlled trials. Clemen et al. (2012), and Palese et al. (2011) were graded as level four studies, as their design was a case controlled study and longitudinal observational study, respectively. Ho and Cheung (2011) is graded as a level five study, as their article was a systematic review and guideline recommendation based on other research. Implications CDC guidelines on PIVCs are based upon outdated research and requires an analysis for possible revision. Currently, PIVCs are discontinued on a routine basis, clinically indicated discontinuation focuses instead on removing the catheter only when necessary. Discontinuing PIVCs when clinically indicated allow for longer indwell times (Rickard et al., 2012). These longer indwell times will lead to less insertions of PIVCs, less catheters used, cost savings to the hospital and patient, and less discomfort for the patient (Gonzalez Lopez et al., 2014). Plan for Implementation Considering that a vast majority of hospitals operate within CDC guidelines, a change would need to be made at that level. The CDC would need to adopt clinically indicated discontinuation of PIVCs as a recommendation for adult patients. These recommendations should include guidelines for assessments as well as maximum thresholds. Ho and Cheung (2011) recommend the nurse to assess the PIVC site at least two times per shift. If phlebitis, IMPLICATIONS FOR PIVC DISCONTINUATION 11 blockage, infiltration, or local infection is found, the PIVC should be replaced immediately (Ho, & Cheung, 2011). Education is an important factor within the PIVC intervention plan. The nurse is the first line of defense against phlebitis. By implementing training and education associated with site assessments, nurses can dramatically increase the efficacy of clinically indicated PIVC discontinuation. Education of the nurse should focus on identifying early signs of phlebitis, as well as higher levels of aseptic insertion techniques. Scales are used for many assessments to assist the nurse in level of care. Creation of a phlebitis scale can be a method in establishing consistent assessments. Having the nurse educate the patient on what the PIVC is, what its function is, along with signs and symptoms of phlebitis, can prove to be invaluable. Equipping the patient with necessary information can help to prevent phlebitis and bacterial infection. Creating and implementing training for the nurses and other healthcare professionals is important. It is equally important to evaluate efficacy of the training and implementations of learned processes. Ho and Cheung (2011) suggest that clinical guidelines be reviewed every five years and should involve: re-educating on current implementation guidelines, carrying out reviews of those guidelines, and conducting audits that review outcomes along with new research,. These reviews can benefit nurses, along with any staff involved with the PIVC. Potential barriers can be staffing levels along with the workload of the nurse. These may lead to the nurse being unable to assess the PIVC site adequately. Oversight and accountability will be key. IMPLICATIONS FOR PIVC DISCONTINUATION 12 Ethical, Cultural, and Spiritual Considerations Choosing to implement PIVC discontinuation when clinically indicated shouldn’t happen without considering the ethical implications. First, these studies are conducted on human subjects. It’s important to recognize that this intervention can have adverse health effects if not done properly. If the nurse fails to assess or fails to correctly assess the PIVC site, phlebitis can lead to sepsis which is a serious health concern (Ho and Cheung, 2011). The study methodology adopted by the researchers was sound. The researchers only chose healthy adult participants to study, considering the possible adverse outcomes. Overall, the benefits of this study outweigh the possible consequences. Though some participants did develop phlebitis in the experimental group, the researchers found no statistically significant increase in the incidences of phlebitis between the routine method and clinically indicated method. Cultural and spiritual sensitivity within the healthcare system has become more important now than ever before. Its relevance has especially been emphasized as countries around the world become more culturally and spiritually diverse. It is the responsibility of the healthcare professional to practice culturally sensitive care and to recognize when certain standard practices may not be normal to others, particularly minority groups or recent immigrants. The process of inserting a PIVC can be traumatic, painful, and discomforting. Though its use is viewed as necessary in a lot of cases, not all patients may understand its purpose. It is important that healthcare providers take the time to explain the purpose and process of using PIVCs to everyone, especially those that may be new to its usage. If language barriers exist, it is important to use a certified hospital translator to ensure that PIVC information is fully understood. This can allow for an informed decision on its use. It is also important to recognize IMPLICATIONS FOR PIVC DISCONTINUATION 13 that some religions and beliefs may also have reservations or even completely forbid the use of PIVCs. Incorporating patient education into aspects of PIVC use, can ensure an adequately informed patient. Gaps in the Literature While the findings of the research found benefits of discontinuing PIVCs based on clinical indication, there are gaps within the literature. The CDC makes it apparent that more research is needed with clinically indicated PIVC discontinuation. With a few of the research studies falling short in population and variability, continuing the current research with larger and more varied patient populations would have a benefit. Further research should focus on nursing assessment of PIVC sites, and aseptic insertion techniques. They can bring further benefit to clinically indicated discontinuation by providing insight into best practices. Another area to consider research would be patient satisfaction along with cost savings, which can further emphasize the benefits of the PIVC intervention. Conclusion Research shows that discontinuing a PIVC only when clinically indicated is more beneficial than by routine. The research finds no increase in incidence of phlebitis when PIVC indwell times exceed routine replacement timeframes. Successful implementation of standards based on clinical indication will rely heavily on nursing assessments, education of both the nurse and patient, and the implementation of a review process. While some gaps in the literature find a need for larger, more varied participant samples, it is clear there are benefits to clinically indicated discontinuation of PIVCs over routine replacement. It is recommended that the CDC evaluate current research for adoption as a recommendation into their guidelines. IMPLICATIONS FOR PIVC DISCONTINUATION 14 References Benbow, M. (2009, January).
