Positive effect of care bundles on patients with central venous catheter insertions at a tertiary hospital in Beijing, China

Facilitators and barriers to evidence adoption for central venous catheters post-insertion maintenance in oncology nurses: a multi-center mixed methods study

BACKGROUND

The post-insertion maintenance of central venous catheters(CVCs)is a common, vital procedure undertaken by nurses. Existing literature lacks a comprehensive review of evidence adoption for CVCs post-insertion maintenance specifically within the oncology context. This investigation assessed evidence-based practice by oncology nurses in the care of CVCs, elucidating facilitators and obstacles to this adoption process.

METHODS

This was a sequential explanatory mixed methods study, executed from May 2022 to April 2023, adhering to the GRAMMS checklist. The study commenced with a cross-sectional study through clinical observation that scrutinized the adoption of scientific evidence for CVC maintenance, analyzing 1314 records from five hospitals in China. Subsequently, a semi-structured, in-depth interview with nurses based on the i-PARIHS framework was conducted to ascertain facilitators and barriers to evidence adoption for CVCs post-insertion maintenance. Fifteen nurses were recruited through purposive sampling. Descriptive statistics were used to summarize quantitative data, while content analysis was used to analyze qualitative data.

RESULTS

An overall compliance rate of 90.0% was observed; however, two domains exhibited a lower adoption rate of less than 80%, namely disinfection of infusion connector and disinfection of skin and catheter. Three barriers and two facilitators were discerned from the interviews. Barriers encompassed (1) difficulty in accessing the evidence, (2) lack of involvement from nurse specialists, and (3) challenges from internal and external environments. Facilitators comprised (1) the positive attitudes of specialist nurses toward evidence application, and (2) the formation of a team specializing in intravenous therapy within hospitals.

CONCLUSION

There exists a significant opportunity to improve the adoption of evidence-based practices for CVC maintenance. Considering the identified barriers and facilitators, targeted interventions should be conceived and implemented at the organizational level to augment oncology evidence-based practice, especially the clinical evidence pertinent to infection control protocols.

TRIAL REGISTRATION

Effects of organizational and individual factors on nurses' practice of central line-associated bloodstream infection prevention

BACKGROUND

This study explored rarely investigated organizational factors (resource support and organizational culture) in conjunction with well-established individual factors (demographic characteristics, knowledge, and awareness) that impact nurses' practice of central line-associated bloodstream infection (CLABSI) prevention.

METHODS

Self-reported questionnaire data were collected from 173 nurses recruited from departments that use central venous catheters (ie, intensive care units, emergency rooms, hemodialysis rooms, and oncology wards) in tertiary hospitals in South Korea. Multiple regression analyses were performed to examine the effects of individual and organizational factors.

RESULTS

Organizational culture (ß = 0.350) had the greatest association with CLABSI prevention practice, followed by awareness (ß = 0.328) and department (ß = -0.217; all ps < 0.01). These variables explained 41.1% of the variance in CLABSI prevention practice (F = 20.996, P < .001). Higher self-reported CLABSI prevention practice was associated with a favorable organizational culture and higher awareness. Emergency room nurses' CLABSI prevention practice was notably inferior as compared to nurses in other departments.

DISCUSSION

Organizational culture is the most significant factor affecting nurses' practice of CLABSI prevention.

CONCLUSIONS

An organizational culture with environmental improvements and resource support as well as infection prevention education and awareness-building programs should be fostered.

Effects of the care given to intensive care patients using an evidence model on the prevention of central line-associated bloodstream infections

It is important to put evidence-based guidelines into practice in the prevention of central line-associated bloodstream infections in intensive care patients. In contrast to expensive and complex interventions, a care bundle that includes easy-to-implement and low-cost interventions improves clinical outcomes. The compliance of intensive care nurses with guidelines is of great importance in achieving these results. The Translating Evidence into Practice Model provides guidance in how to implement the necessary guidelines. This quasi-experimental study used a post-test control group design in nonequivalent groups and was conducted in the anesthesia intensive care unit of a tertiary-level training and research hospital. All patients who were hospitalized in the intensive care unit, who had a central line during the study, and who met the inclusion criteria were included in the sample. The care bundle comprised education, and protocols for hand hygiene and the aseptic technique, maximum sterile barrier precautions, central line insertion trolley, and management of nursing care. To analyze the data, the independent samples t-test, the Mann-Whitney U test, chi-square test, dependent samples t-test, rate ratio, and relative risk were used with 95% confidence intervals. The rate of central line-associated bloodstream infections was significantly lower in the intervention group (2.85/1000 central line days) than in the control group (3.35/1000 central line days) (P = 0.042). The number of accesses to the central line by the nurses decreased significantly in the intervention group compared to the control group (P < 0.001). The mean score for the nurses' evidence-based guideline post-education knowledge (70.80 ± 12.26) was significantly higher than that pre-education (48.20 ± 14.66) (P < 0.001). Compliance with the guideline recommendations in central line-related nursing interventions and in the central line insertion process was significantly better in the intervention group than in the control group in many interventions (P < 0.05). The mean score for the nurses' attitude towards evidence-based nursing increased significantly over time (59.87 ± 7.23 at the 0th month; 63.79 ± 7.24 at the 6th month) (P < 0.001). Nursing care given by implementing the central line care bundle with the Translating Evidence into Practice Model affected the measures. Thanks to the implementation of the care bundle, the rate of infections and the number of accesses to the central line decreased, while the critical care nurses' knowledge of evidence-based guidelines, compliance with the guideline recommendations in central line-related nursing interventions, and attitudes towards evidence-based nursing improved.

Risk factors for catheter-related bloodstream infections in patients with intestinal failure undergoing home parenteral nutrition: a single-center study

PURPOSE

The incidence and risk factors of catheter-related bloodstream infections (CRBSI) in patients with intestinal failure (IF) have not been established, partly because catheter management methods vary from different facilities. This study aimed to identify the risk factors and incidence rate of CRBSIs in patients with IF who were given prophylactic treatment.

METHODS

Sixteen patients with IF who required home parenteral nutrition were enrolled in this study. Prophylactic management of CRBSI included monthly ethanol lock therapy and standardized infection prevention education. The outcomes included the incidence and risk factors of CRBSI.

RESULTS

The median incidence rate of CRBSI was 1.2 per 1000 catheter days. Univariate analysis showed that the risk of developing CRBSI was significantly associated with short bowel syndrome (< 30 cm) (p = 0.016). Other relevant findings included a significant negative correlation between serum albumin and CRBSI rate (r = - 0.505, p = 0.046), and past history of mixed bacterial infections was significantly associated with increased CRBSI rate (p = 0.013).

CONCLUSION

CRBSIs can still develop despite undergoing prophylactic management. Risk factors for CRBSI include the residual intestinal length, nutritional status, and susceptibility to certain microorganisms.

Knowledge, Skills, and Compliance of Nurses Related to Central Line-Associated Bloodstream Infection in the Cardiovascular Department at King Faisal Hospital and Research Centre, Riyadh

Background and objective Healthcare-associated infections (HAIs), especially central line-associated bloodstream infections (CLABSI), are among the most critical public health problems worldwide. Knowledge, attitude, and skills of nurses are vital in HAI prevention. In this study, we aimed to assess nurses' knowledge, skills, and compliance related to CLABSI. Method This study was conducted in a heart center as a prospective interventional study. Eighty nurses were selected after obtaining their consent to participate in the pretest, posttest, and skills review. Qualified nurses registered with the Saudi Council and working for at least one month in the relevant unit at the time of the study were included. Nurse managers, interns, and student nurses were excluded. Nurses' skills were analyzed using a competency-based checklist approved by the hospital. Results We enrolled 80 participants in our study. The majority of the participants (51.25%) fell under the age group of 25-34 years. There were 68 females (85%). Participants with an experience of 6-10 years constituted the biggest proportion (37.5%) in the cohort in terms of work experience. The mean CLABSI knowledge-related pretest and posttest scores were 6.7 ±1.09 and 6.8 ±1.11, respectively, while the CLABSI compliance scores were 8.1 ±0.99 and 8.3 ±0.97, respectively. Conclusion Based on our findings, clinical experience of more than five years is associated with good CLABSI knowledge and compliance among nurses. Nurses' level of education also had a significant relationship with CLABSI pretest and posttest scores.

Microbial Repercussion on Hemodialysis Catheter-Related Bloodstream Infection Outcome: A 2-Year Retrospective Study

Background

Albeit growing technical advances in the design of hemodialysis catheters, intravascular catheter-related bloodstream infection (CRBSI) still represents an utmost clinical challenge to the health-care workers (HCWs). Data regarding the influence of the culprit organism on the scenario of CRBSI in the literature are extremely lacking. Thereby, this research was carried out.

Methods

We undertook a retrospective cohort study over an interval of 2 years, involving patients who underwent regular hemodialysis via catheters in the Renal Dialysis Unit (RDU) of Dr. Soliman Fakeeh Hospital (DSFH), Jeddah, Kingdom of Saudi Arabia (KSA). The study enrolled 139 patients (56.8% females and 43.2% males), with mean age of 60.79 ± 11.45 years.

Results

The aggregate rate of CRBSI was 5.1/1000 catheter days. Amongst the 139 study candidates confirmed of having CRBSI, while 69.8% of CRBSIs were ascribed to Gram-positive cocci, about one-third of the infectious episodes were secondary to Gram-negative bacilli. Interestingly, fever was the most common presentation of S. aureus CRBSI compared to CoNS and Gram-negative bacilli CRBSIs (20.9% versus 12.9% versus 6.5%, p= 0.0001), whereas CRBSIs due to CoNS were presented mainly with rigors (19.4%). Of note, CRBSIs caused by Gram-negative bacilli had a tendency to manifest with unusual symptoms such as vomiting or hypotension. Besides, they were more prone to involve hospitalization or ICU admission. In this study, no mortality was attributed to CRBSIs.

Conclusion

Our study disclosed that the illicit organism has a repercussion on the clinical presentation as well as the fate of CRBSI among hemodialysis patients. This highlights the worth of identifying the infected cases in a periodic manner, to avoid the occurrence of devastating complications. A large body of work from various hemodialysis centers should take place in the near future so as to provide more insight in this perspective.

Post-craniotomy fever and its associated factors in patients with traumatic brain injury

BACKGROUND

Fever frequently occurs in patients with traumatic brain injury and can cause secondary damage to the brain. Critical care nurses play essential roles in assessing and managing fever in these patients.

AIM

The study aimed to (a) examine the fever causes in and condition of neurosurgical patients with traumatic brain injury in intensive care, (b) identify the factors associated with fever, and (c) determine the effects of fever on hospital stay and prognosis.

STUDY DESIGN

This study is a retrospective observational design.

METHODS

Data were collected through chart reviews of 93 traumatic brain injury patients admitted to a teaching hospital's intensive care unit for postoperative care. Fever was defined as at least one episode of body temperature >38°C.

RESULTS

Of the 93 patients, 76 developed a fever within 1-week post-craniotomy. Of these, 49 were infection-related and 27 were unexplained. Results of logistic regression showed that the preoperative Glasgow coma scale score (ß = -.323; P = .013) and length of intubation (ß = .480; P = .005) were the key predictors of unexplained post-craniotomy fever, and these two variables (ß = -.494; P < .001 and ß = .479; P = .006, respectively) were also the key predictors of infection-related fever.

CONCLUSION

A significant portion of patients developed a fever during the first post-craniotomy week. Patients with a lower pre-craniotomy Glasgow coma scale score and a longer intubation length were at a greater risk for both infection-related fever and unexplained fever. Patients with fever had a bad outcome score.

RELEVANCE TO CLINICAL PRACTICE

Critical care nurses should closely monitor traumatic brain injury patients' body temperatures and employ evidence-based infection prevention and control measures to minimize their infection risks. Respiratory care and intensive care unit Liberation Bundle should be reinforced to liberate these patients from mechanical ventilation and its associated complications.
