Early mortality attributable to PICC-lines in 4 public hospitals of Marseille from 2010 to 2016 (Revised V3)

Impact of central-line-associated bloodstream infections and catheter-related bloodstream infections: a systematic review and meta-analysis

BACKGROUND

Accurate effect estimates are needed to inform input parameters of health economic models. Central-line-associated bloodstream infections (CLABSIs) and catheter-related bloodstream infections (CRBSIs) are different definitions used for central-line bloodstream infections and may represent dissimilar patients, but previous meta-analyses did not differentiate between CLABSIs/CRBSIs.

AIM

To determine outcome effect estimates in CLABSI and CRBSI patients, compared to uninfected patients.

METHODS

PubMed, Embase, and CINAHL were searched from January 2000 to March 2024 for full-text studies reporting all-cause mortality and/or hospital length of stay (LOS) in adult inpatients with and without CLABSI/CRBSI. Two investigators independently reviewed all potentially relevant studies and performed data extraction. Odds ratio for mortality and mean difference in LOS were pooled using random-effects models. Risk of study bias was assessed using ROBINS-E.

FINDINGS

Thirty-six studies were included. Sixteen CLABSI and 12 CRBSI studies reported mortality. The mortality odds ratios of CLABSIs and CRBSIs, compared to uninfected patients, were 3.19 (95% CI: 2.44, 4.16; I2 = 49%) and 2.47 (95% CI: 1.51, 4.02; I2 = 82%), respectively. Twelve CLABSI and eight CRBSI studies reported hospital LOS; only three CLABSI studies and two CRBSI studies accounted for the time-dependent nature of CLABSIs/CRBSIs. The mean differences in LOS for CLABSIs and CRBSIs compared to uninfected patients were 16.14 days (95% CI: 9.27, 23.01; I2 = 91%) and 16.26 days (95% CI: 10.19, 22.33; I2 = 66%), respectively.

CONCLUSION

CLABSIs and CRBSIs increase mortality risk and hospital LOS. Few published studies accounted for the time-dependent nature of CLABSIs/CRBSIs, which can result in overestimation of excess hospital LOS.

Central venous access device terminologies, complications, and reason for removal in oncology: a scoping review

BACKGROUND

Lack of agreed terminology and definitions in healthcare compromises communication, patient safety, optimal management of adverse events, and research progress. The purpose of this scoping review was to understand the terminologies used to describe central venous access devices (CVADs), associated complications and reasons for premature removal in people undergoing cancer treatment. It also sought to identify the definitional sources for complications and premature removal reasons. The objective was to map language and descriptions used and to explore opportunities for standardisation.

METHODS

A systematic search of MedLine, PubMed, Cochrane, CINAHL Complete and Embase databases was performed. Eligibility criteria included, but were not limited to, adult patients with cancer, and studies published between 2017 and 2022. Articles were screened and data extracted in Covidence. Data charting included study characteristics and detailed information on CVADs including terminologies and definitional sources for complications and premature removal reasons. Descriptive statistics, tables and bar graphs were used to summarise charted data.

RESULTS

From a total of 2363 potentially eligible studies, 292 were included in the review. Most were observational studies (n = 174/60%). A total of 213 unique descriptors were used to refer to CVADs, with all reasons for premature CVAD removal defined in 84 (44%) of the 193 studies only, and complications defined in 56 (57%) of the 292 studies. Where available, definitions were author-derived and/or from national resources and/or other published studies.

CONCLUSION

Substantial variation in CVAD terminology and a lack of standard definitions for associated complications and premature removal reasons was identified. This scoping review demonstrates the need to standardise CVAD nomenclature to enhance communication between healthcare professionals as patients undergoing cancer treatment transition between acute and long-term care, to enhance patient safety and rigor of research protocols, and improve the capacity for data sharing.

Clinical factors associated with peripherally inserted central catheters (PICC) related bloodstream infections: a single centre retrospective cohort

BACKGROUND

Despite their spread in daily practice, few data is available on clinical factors associated with peripherally inserted central catheter (PICC)-related bloodstream infections (PR-BSI). We aimed to assess the PR-BSI incidence, microbiology, and factors associated with PR-BSI with a focus on clinical symptoms.

METHODS

We conducted a retrospective cohort study in a French university hospital. We screened all PICC insertions performed from April 1st, 2018, to April 1st, 2019, and included PICC insertions in adult patients. We assessed the PR-BSI incidence, the factors associated with PR-BSI using a Cox model, and negative and positive predictive values (NPVs and PPVs) of each clinical sign for PR-BSI.

RESULTS

Of the 901 PICCs inserted in 783 patients (38,320 catheters days), 214 PICCs (24%) presented with a complication. The most prevalent complication was PR-BSI (1.9 per 1000 catheter days; 8.1% of inserted PICCs ). Enterobacterales (N = 27, 37%) and coagulase negative Staphylococci (N = 24, 33%), were the main microorganisms responsible for PR-BSI. Factors independently associated with occurrence of PR-BSI were fever (hazard ratio 13.21, 95% confidence interval 6.00-29.11, p < 0.001) and chills (HR 3.66, 95%CI 1.92-6.99, p < 0.001). All clinical signs and a duration of PICC maintenance ≥ 28 days, had a low PPVs (≤ 67.1%) but high NPVs (≥ 92.5%) for PR-BSI.

CONCLUSIONS

Monitoring of clinical signs, especially fever and chills, with caution and limitation of device maintenance duration, could improve PICC management.

[Monitoring of PICC lines in hospitals as part of an approach to improving the quality of care]

The hospital hygiene operational team at the Haguenau Hospital Center in the Bas-Rhin region conducted prospective surveillance of the condition of PICC line dressings both at the time of application and during use for hospitalized patients in 2019 and 2021. Infectious and mechanical complications were identified in both periods. A report on the results of the first survey was proposed to the institution's professionals. Awareness campaigns on the subject of dressing repair and pulsed rinsing were carried out, and nurses were invited to attend training sessions in the form of practical work on PICC care. The second survey measured the extent, progress, and impact of training on quality of care.

Subcutaneously administered antibiotics: a review

BACKGROUND

Subcutaneous (SC) administration of antibiotics represents an attractive alternative to the intravenous (IV) route.

METHODS

We performed a systematic electronic search of PubMed and the Cochrane Library for all articles published prior to April 2022, using the key terms and MeSH terms 'subcutaneous', 'antibiotic' and the international non-proprietary name of antibiotics.

RESULTS

A total of 30 studies were selected including data on the efficacy and tolerability of antibiotics, and seven studies that were conducted in healthy subjects, for relevant information regarding the safety and tolerability of antibiotics. Comparative studies have shown that efficacy is similar for the SC and IV routes for ceftriaxone, teicoplanin and ertapenem. The SC use of other antibiotics such as ampicillin, ceftazidime, cefepime, piperacillin/tazobactam, metronidazole and fosfomycin has also been described. These results have largely been corroborated by pharmacokinetic/pharmacodynamic analyses, especially for time-dependent antibiotics. Complications of SC treatment are rarely severe, with no reports of bacteraemia or other invasive infection related to this route of administration. Therapeutic drug monitoring has been proposed to adapt the dose and avoid toxicity.

DISCUSSION

The rationale for using SC administration of ceftriaxone, ertapenem and teicoplanin is strong in patients with non-severe infections. It is already commonly practised in some countries, particularly in France. Other antibiotics could be administered subcutaneously, but further studies are needed to validate their use in clinical practice. Further research is needed to safely generalize and optimize this route of administration whenever possible. This would reduce the risk of catheter-related infections and their complications, together with the length of hospital stay.

Complications of peripherally inserted central catheters in adult hospitalized patients and outpatients in the KTFIXPICC study: A randomized controlled trial evaluating a fixation device KT FIX Plussystem

BACKGROUND

Poor securement potentiates Peripherally inserted central catheters (PICC) complications. A dressing device (KT FIX Plus) offers stronger skin attachment, which may reduce the risk of dressing disruption. We aimed to evaluate this device.

METHODS

We conducted a single-center parallel-group open-label randomized controlled trial. Hospitalized and outpatient consecutive adults requiring PICCs were randomized to KT FIX Plus or standard of care (SOC). The primary endpoint was the composite of PICC-associated complications until removal, including occlusion, migration, accidental withdrawal, infection, thrombosis, and hematoma.

RESULTS

No statistically significant difference was observed in terms of complications: 67 (35%) in the KT FIX Plus group vs 36 (37%) in the SOC group (log-rank P = 0.76). In multivariate Cox analysis, independent risk factors for PICC-associated complications were obesity (adjusted hazard ratio (aHR), 1.08, P < .001) and diabetes (aHR, 1.85, P = .039), adjusting for chronic renal failure, number of lumens, catheter/vein diameter ratio and duration of home-based care. Multiple lumen catheters increased the risk of accidental withdrawal and migration (HR, 2.4, P = .008).

CONCLUSIONS

In our study, the use of KT FIX Plus did not reduce the risk of complications adjusting for other risk factors such as obesity and diabetes. The number of catheter lumens is one of the modifiable factors to reduce complications. Further studies are required to find the best securement and dressing system.

Risk of catheter-related bloodstream infection associated with midline catheters compared with peripherally inserted central catheters: A meta-analysis

Background

Both midline catheters (MCs) and peripherally inserted central catheters (PICCs) can cause catheter‐related bloodstream infection (CRBSI), but the prevalence associated with each is not clear.

Objective

To compare the risk of CRBSI between MCs and PICCs with a meta‐analysis.

Methods

The Web of Science Core Collection, PubMed, Scopus, Embase, The Cochrane Library and ProQuest were searched. All studies comparing the risk of CRBSI between MCs and PICCs were included. Selected studies were assessed for methodological quality using the Downs and Black checklist. Two authors independently assessed the literature and extracted the data. A fixed effects model was used to generate estimates of CRBSI risk in patients with MCs versus PICCs. Publication bias was evaluated, and meta‐analyses were conducted with RevMan 5.3.

Results

A total of 167 studies were identified. Ten studies were collected, involving 33,322 patients. The prevalence of CRBSI with MCs and PICCs was 0.58% (40/6,900) and 0.48% (127/26,422), respectively. Meta‐analysis showed that the prevalence of CRBSI was not significantly different between MCs and PICCs (RR = 0.77, 95% CI: 0.50–1.17, p = .22). While the result showed that the prevalence of CRBSI with MCs was lower than that with PICCs (RR = 0.55, 95% CI: 0.33–0.92, p = .02) after poor‐quality studies were removed. The sensitivity analysis shows that the results from this meta‐analysis are fair in overall studies and non‐poor‐quality studies. All studies have no significant publication bias.

Conclusions

This study provides the first systematic assessment of the risk of CRBSI between MCs and PICCs and provides evidence for the selection of appropriate vascular access devices for intravenous infusion therapy in nursing. The prevalence of CRBSI was not significantly different between them.

Five-year outcome of peripherally inserted central catheters in adults: a separated infectious and thrombotic complications analysis

OBJECTIVE

To assess infectious and thrombotic complications of peripherally inserted central catheters (PICCs) in adults.

DESIGN

A 5-year prospective cohort study.

SETTING

Tertiary-care teaching hospital in Seville, Spain.

PATIENTS

Adult patients undergoing PICC insertion.

METHODS

Catheter-associated bloodstream infection (CABSI) including catheter-related bloodstream infection (CRBSI), primary bacteremia (PB), and upper extremity deep vein thrombosis (UEDVT) were recorded. Independent predictors of complications were assessed by multivariate analysis.

RESULTS

In total, 1,142 PICCs were inserted, with 153,191 catheter days (median, 79). Complications included 66 cases of CABSI (5.78%; 0.43‰ catheter days), 38 cases of CRBSI (3.33%; 0.25‰ catheter days), 28 cases of PB (2.45%; 0.18‰ catheter days), and 23 cases of UEDVT (2.01%; 0.15‰ catheter days). The median times to infection were 24, 41, and 60 days for CRBSI, PB, and UEDVT, respectively. Parenteral nutrition (odds ratio [OR], 3.40; 95% confidence interval [CI], 1.77-6.52) and admission to the hematology ward (OR, 4.90; 95% CI, 2.25-10.71) were independently associated with CRBSI and PB, respectively. Admission to the hematology ward (OR, 12.46; 95% CI, 2.49-62.50) or to the oncology ward (OR, 7.89; 95% CI, 1.77-35.16) was independently associated with UEDVT. The crude mortality rate was 24.8%. Only 2 patients died of complications.

CONCLUSIONS

PICCs showed a low rate of thrombotic and infectious complications. Compared to PB, CRBSI showed significantly different risk factors, a higher incidence density per catheter days, and a shorter median time to infection. Separate analyses of CRBSI and PB are more specific and clinically useful when analyzing infectious complications.

Peripherally inserted central catheters: a hidden emerging cause of infection outbreaks

In our institution, between January 2010 and December 2017, 15 140 peripherally inserted central catheters (PICCs) were inserted in 12 314 patients. Using time-series analysis to evaluate the annual historical trend (AHT), we observed a significant increase in bloodstream infections (BSIs; AHT = 24; p < 0.001) and associated deaths (AHT = 3; p 0.02) in patient with PICCs. The risk of experiencing a BSI was significantly higher in patients with PICCs (odds ratio = 9.6; 95% confidence interval, 9.08–10.18; p < 0.001). To reduce PICC-related BSIs and their related mortality, it is important to limit the overuse of PICCs and to implement a ‘no PICC’ policy by limiting the insertion of PICCs to situations without other available options.
