Nurse-driven protocols and the prevention of catheter-associated urinary tract infections: A systematic review

A nurse-led multifaceted intervention for the optimal use of indwelling urinary catheters at a tertiary care center: A before-after trial

BACKGROUND

Few interventional studies of catheter-associated urinary tract infection (CAUTI) have been conducted to optimize indwelling urinary catheter (IUC) use in Japan.

METHODS

The nurse-led, before-after study was conducted at a tertiary care center from June 2018 through May 2022. The intervention included 1) the provision of appropriate indications for IUC use, 2) prospective feedback to the primary care providers by ward nurses on unnecessary/inappropriate IUC use with two, separate interventional phases, the first involving intensive care units (ICU) only, the second involving ICU and general wards, and 3) proactive feedback by Infectious diseases physicians in the Infection Control department to the primary care providers regarding IUC discontinuation upon discharge from the ICU.

RESULTS

During the first phase involving the implementation of the intervention only in the ICU, the indwelling urinary catheter-device utilization ratio (IUC-DUR) trend in the general wards decreased by 1.5 % (P = 0.01). However, the addition of the intervention to the general wards in the second phase led to a 2 % increase in the trend (P = 0.010). The CAUTI incidence in neither the ICU nor the general wards changed significantly.

CONCLUSIONS

Although providing feedback on IUC removal at discharge from the ICU and appropriate indications for urinary catheter insertion can reduce inappropriate urinary catheter use, the nurse-led intervention alone was inadequate for reducing the CAUTI incidence.

Enzymatically Built Nanoenabled Antimicrobial Coating on Urinary Catheters

Catheter-associated urinary tract infections represent a major share of nosocomial infections, and are associated with longer periods of hospitalization and a huge financial burden. Currently, there are only a handful of commercial materials that reduce biofilm formation on urinary catheters, mostly relying on silver alloys. Therefore, we combined silver-phenolated lignin nanoparticles with poly(carboxybetaine) zwitterions to build a composite antibiotic-free coating with bactericidal and antifouling properties. Importantly, the versatile lignin chemistry enabled the formation of the coating in situ, enabling both the nanoparticle grafting and the radical polymerization by using only the oxidative activity of laccase. The resulting surface efficiently prevented nonspecific protein adsorption and reduced the bacterial viability on the catheter surface by more than 2 logs under hydrodynamic flow, without exhibiting any apparent signs of cytotoxicity. Moreover, the said functionality was maintained over a week both in vitro and in vivo, whereby the animal models showed excellent biocompatibility.

Roles of Two-Dimensional Materials in Antibiofilm Applications: Recent Developments and Prospects

Biofilm-associated infections pose a significant challenge in healthcare, constituting 80% of bacterial infections and often leading to persistent, chronic conditions. Conventional antibiotics struggle with efficacy against these infections due to the high tolerance and resistance induced by bacterial biofilm barriers. Two-dimensional nanomaterials, such as those from the graphene family, boron nitride, molybdenum disulfide (MoS2), MXene, and black phosphorus, hold immense potential for combating biofilms. These nanomaterial-based antimicrobial strategies are novel tools that show promise in overcoming resistant bacteria and stubborn biofilms, with the ability to circumvent existing drug resistance mechanisms. This review comprehensively summarizes recent developments in two-dimensional nanomaterials, as both therapeutics and nanocarriers for precision antibiotic delivery, with a specific focus on nanoplatforms coupled with photothermal/photodynamic therapy in the elimination of bacteria and penetrating and/or ablating biofilm. This review offers important insight into recent advances and current limitations of current antibacterial nanotherapeutic approaches, together with a discussion on future developments in the field, for the overall benefit of public health.

AMPlifying metabolic screening for inpatients on antipsychotic medications with a nurse-driven protocol

INTRODUCTION

Patients on antipsychotic medications are at higher risk of developing metabolic syndrome; nevertheless, metabolic screening for patients on antipsychotics is suboptimal.

METHODS

This project developed and implemented AMP (Antipsychotic Metabolic screening Protocol), a nurse-driven protocol on inpatient psychiatric units that allowed nursing staff to collect all components of a metabolic screening. Nurses working on units with AMP were surveyed pre- and post-implementation on perception of AMP and empowerment.

RESULTS

AMP significantly increased overall metabolic screening as well as the most frequently missing component (lipid panel). The screening rates pre-intervention were similar to those found in the literature (on average, only two-thirds of patients were screened). However, AMP improved the rate such that nine out of every ten patients on the units were screened. Nurses had a negative perception and no change in empowerment from AMP implementation.

CONCLUSIONS

AMP can be used to increase metabolic screening for patients on antipsychotics. Further research is needed to better understand adoptability of nurse-driven protocols in the psychiatric inpatient setting as well as other applications, such as smoking cessation or safety sitters.

Empowering telemetry technicians and enhancing communication to improve in-hospital cardiac arrest survival

Delays in treatment of in-hospital cardiac arrests (IHCAs) are associated with worsened survival. We sought to assess the impact of a bundled intervention on IHCA survival in patients on centralised telemetry. A retrospective quality improvement study was performed of a bundled intervention which incorporated (1) a telemetry hotline for telemetry technicians to reach nursing staff; (2) empowerment of telemetry technicians to directly activate the IHCA response team and (3) a standardised escalation system for automated critical alerts within the nursing mobile phone system. In the 4-year study period, there were 75 IHCAs, including 20 preintervention and 55 postintervention. Cox proportional hazard regression predicts postintervention individuals have a 74% reduced the risk of death (HR 0.26, 95% CI 0.08 to 0.84) during a code and a 55% reduced risk of death (HR 0.45, 95% CI 0.23 to 0.89) prior to hospital discharge. Overall code survival improved from 60.0% to 83.6% (p=0.031) with an improvement in ventricular tachycardia/ventricular fibrillation (VT/VF) code survival from 50.0% to 100.0% (p=0.035). There was no difference in non-telemetry code survival preintervention and postintervention (71.4% vs 71.3%, p=0.999). The bundled intervention, including improved communication between telemetry technicians and nurses as well as empowerment of telemetry technicians to directly activate the IHCA response team, may improve IHCA survival, specifically for VT/VF arrests.

Consent and Complications in Health Care: The Italian Context

Informed consent is the manifestation of the will that a patient freely expresses toward a medical treatment. The physician is responsible for acquiring informed consent for both medical and nursing procedures. Informed consent represents a juridical-deontological tool that allows therapeutic choices to be shared with the user after having exhaustively explained the risks and benefits of the procedure itself. In fact, the physician has an obligation to provide the patient with clear and comprehensible information about the type of service, the methods of delivery, the benefits, the risks, even unforeseeable ones, and the complications. According to Italian legal guidelines, in cases of presumed health responsibility, the health professional accused of negligence will have to demonstrate that any complication that has arisen, although foreseeable, was not preventable. Through the analysis of a clinical case relating to the procedure of insertion of a bladder catheter performed by a nurse and a review of the literature, the authors explain the importance of the information that must be provided to the patient before carrying out any invasive procedure, even if not performed by the doctor. The authors describe the problem in the Italian context and propose a possible solution.

Using statistical process control charts to measure changes from a nurse-driven protocol to remove urinary catheters

BACKGROUND

Implementing a nurse-driven protocol (NDP) to remove indwelling urinary catheters is a strategy to reduce catheter-associated urinary tract infections (CAUTI). The purpose of this project was to implement a comprehensive NDP to reduce indwelling urinary catheter utilization and CAUTI rates at a large academic health system.

METHODS

Statistical process control charts, a quality improvement method, was used to identify special cause variation. A formal protocol was developed to provide guidance for nurses to remove indwelling urinary catheters when no longer indicated. Changes were also made within the electronic health record.

RESULTS

Signals of improvement were not noted on the Statistical process control charts for urinary catheter utilization or CAUTI rates. The frequency with which the NDP was documented (process measure) was assessed, showing it is used approximately 600 times each month. Of those catheters removed by the NDP, an average of 6% were reinserted within 48 hours (balancing measure).

DISCUSSION

Our findings differed from other literature as we did not see a reduction in urinary catheter utilization after implementing a NDP. However, our project adds to the literature as we also evaluated process and balancing measures.

CONCLUSIONS

A NDP for urinary catheter removal provides nurses with the autonomy to remove catheters when no longer indicated; however, other interventions should be added to a comprehensive CAUTI-prevention program.

A co-created nurse-driven catheterisation protocol can reduce bladder distension in acute hip fracture patients - results from a longitudinal observational study

Background

Urinary retention is common in elderly patients undergoing acute hip fracture surgery. Avoiding overfilling the urinary bladder is important to avoid detrusor muscle damage and associated motility problems. The aim of this study was to analyse associations between the co-creation of a nurse-driven urinary catheterisation protocol and the incidence of bladder distension in patients undergoing hip fracture surgery.

Methods

This is a single-centre implementation intervention with a retrospective longitudinal observation design, using five measures points, spanning from June 2015 to March 2020. The intervention was theory driven and the participants, together with the facilitators and researcher, co-created a nurse-driven urinary catheterisation protocol. Data were retrieved from the hip fracture register. Uni- and multivariable logistic regressions were used for analyses of changes in bladder distension and urinary volume of ≥500 ml over the years.

Results

A total of 3078 patients were included over a five-year period. The implementation intervention was associated with a reduction in the proportion of patients with bladder distension of 31.5% (95% confidence interval 26.0–37.0), from year 1 to year 5. The multivariable analysis indicated a 39% yearly reduction in bladder distension, OR 0.61 (95% confidence interval 0.57–0.64, p <  0001). There was a reduction in the proportion of patients with a bladder volume of ≥500 ml of 42.8% (95% confidence interval 36.2–49.4), from year 1 to year 5. The multivariable analysis found a 41% yearly reduction in patients with a bladder volume of ≥500 ml, OR 0.59 (95% confidence interval 0.55–0.64, p <  0.0001). The intervention was associated with improved documentation of both catheter indications and removal plans.

Conclusion

The use of predefined catheter indications and a tighter bladder scanning schedule were associated with a reduction in the incidence of both bladder distension and urine volume ≥ 500 ml in hip fracture patients. Registered nurses can play an active role in the facilitation of timely and appropriate catheter treatment in patients with hip fractures.

Budget impact analysis of a multifaceted nurse-led intervention to reduce indwelling urinary catheter use in New South Wales Hospitals

BACKGROUND

In hospitals, catheter acquired urinary tract infection causes significant resource waste and discomfort among admitted patients. An intervention for reducing indwelling catheterisations - No-CAUTI - was trialled across four hospitals in New South Wales, Australia. No-CAUTI includes: train-the-trainer workshops, site champions, compliance audits, and point prevalence surveys. The trial showed reductions on usual care catheterisation rates at 4- and 9-month post-intervention. This result was statistically non-significant; and post-intervention catheterisation rates rebounded between 4 and 9 months. However, No-CAUTI showed statistically significant catheterisation decreases for medical wards, female patients and for short-term catheterisations. This study presents a budget impact analysis of a projected five year No-CAUTI roll out across New South Wales public hospitals, from the cost perspective of the New South Wales Ministry of Health.

METHODS

Budget forecasts were made for five year roll outs of: i) No-CAUTI; and ii) usual care, among all public hospitals in New South Wales hosting overnight stays (n=180). The roll out design maintains intervention effectiveness with ongoing workshops, quality audits, and hospital surveys. Forecasts of catheterisations, procedures and treatments were modelled on No-CAUTI trial observations. Costs were sourced from trial records, the Medical Benefits Scheme, the Pharmaceutical Benefits Scheme and public wage awards. Cost and parameter uncertainties were considered with sensitivity scenarios.

RESULTS

The estimated five-year No-CAUTI roll-out cost was $1.5 million. It had an overall budget saving of $640,000 due to reductions of 100,100 catheterisations, 33,300 urine tests and 6,700 antibiotics administrations. Non-Metropolitan hospitals had a net saving of $1.2 million, while Metropolitan hospitals had a net cost of $0.54 million.

CONCLUSIONS

Compared to usual care, NO-CAUTI is expected to realise overall budget savings and decreases in catheterisations over five years. These findings allow a consideration of the affordability of a wide implementation.

Economic evaluation of quality improvement interventions to prevent catheter-associated urinary tract infections in the hospital setting: a systematic review

BACKGROUND

Hospitals have implemented diverse quality improvement (QI) interventions to reduce rates of catheter-associated urinary tract infections (CAUTIs). The economic value of these QI interventions is uncertain.

OBJECTIVE

To systematically review economic evaluations of QI interventions designed to prevent CAUTI in acute care hospitals.

METHODS

A search of Ovid MEDLINE, Econlit, Centre for Reviews & Dissemination, New York Academy of Medicine's Grey Literature Report, WorldCat, IDWeek conference abstracts and prior systematic reviews was conducted from January 2000 to October 2020.We included English-language studies of any design that evaluated organisational or structural changes to prevent CAUTI in acute care hospitals, and reported programme and infection-related costs.Dual reviewers assessed study design, effectiveness, costs and study quality. For each eligible study, we performed a cost-consequences analysis from the hospital perspective, estimating the incidence rate ratio (IRR) and incremental net cost/savings per hospital over 3 years. Unadjusted weighted regression analyses tested predictors of these measures, weighted by catheter days per study.

RESULTS

Fifteen unique economic evaluations were eligible, encompassing 74 hospitals. Across 12 studies amenable to standardisation, QI interventions were associated with a 43% decline in infections (mean IRR 0.57, 95% CI 0.44 to 0.70) and wide ranges of net costs (mean US$52 000, 95% CI -$288 000 to $392 000), relative to usual care.

CONCLUSIONS

QI interventions were associated with large declines in infection rates and net costs to hospitals that varied greatly but that, on average, were not significantly different from zero over 3 years. Future research should examine specific practices associated with cost-savings and clinical effectiveness, and examine whether or not more comprehensive interventions offer hospitals and patients the best value.

Effect of Cluster Nursing Based on Risk Management Strategy on Urinary Tract Infection in Patients With Severe Craniocerebral Injury

Objective

To observe the effect of cluster nursing based on risk management strategy in the management of urinary tract infection in patients with severe craniocerebral injury.

Methods

A total of 116 patients with severe craniocerebral injury who were admitted to our hospital from March 2019 to March 2021 were included. They were divided into the control group (58 patients) and the observation group (58 patients). The control group received routine nursing care and the observation group received cluster nursing based on risk management strategy. The incidence of catheter-associated urinary tract infection (CAUTI), the results of bacterial culture on the surface of the urinary catheter, the incidence of nursing risk events, the duration of placing the urinary catheter, the length of hospital stay, and hospital costs as well as the patient satisfaction score were compared between the two groups. The knowledge, attitude, and practice scale for prevention of catheter infection and the competence evaluation scale of nurses were used to evaluate the sense-control ability and core competence of the interveners.

Results

The total incidence of CAUTI in the observation group was (6.90%) lower than that in the control group (20.69%) (p < 0.05). The bacterial culture results on the catheter surface of patients in the observation group before and after 6 and 12 h of catheter cleaning were better than those of patients in the control group (p < 0.05). The duration of indwelling urinary catheter, hospitalization time, and hospitalization expenses of patients in the observation group were lower than those of patients in the control group (p < 0.05). The incidence rate of nursing risk events in the observation group was (1.72%) lower than that in the control group (11.86%) (p < 0.05). The overall satisfaction score of patients and the control and core ability scores of nursing staff in the observation group were higher than those in the control group (p < 0.05).

Conclusion

Cluster nursing based on risk management strategy can effectively reduce the incidence of nursing risk events and the probability of UTI in patients with severe craniocerebral injury, shorten the duration of indwelling urinary catheter and hospitalization.

Prediction of Poststroke Urinary Tract Infection Risk in Immobile Patients Using Machine Learning: a observational cohort study

BACKGROUND

Urinary tract infection (UTI) is one of major nosocomial infections significantly affecting the outcomes of immobile stroke patients. Previous studies have identified several risk factors, but it's still challenging to accurately estimate personal UTI risk.

OBJECTIVES

We aimed to develop predictive models for UTI risk identification for immobile stroke patients.

METHODS

Research data were collected from our previous multi-centre study. Derivation cohort included 3982 immobile stroke patients collected from November 1, 2015 to June 30, 2016; external validation cohort included 3837 patients collected from November 1, 2016 to July 30, 2017. 6 machine learning models and an ensemble learning model were derived based on 80% of derivation cohort and effectiveness was evaluated with the remaining 20%. We used Shapley additive explanation values to determine feature importance and examine the clinical significance of prediction models.

RESULTS

2.59% (103/3982) patients were diagnosed with UTI in derivation cohort, 1.38% (53/3837) in external cohort. The ensemble learning model performed the best in area under the receiver operating characteristic (ROC) curve in internal validation (82.2%); second best in external validation (80.8%). In addition, the ensemble learning model performed the best sensitivity in both internal and external validation sets (80.9% and 81.1%, respectively). We also identified seven UTI risk factors (pneumonia, glucocorticoid use, female sex, mixed cerebrovascular disease, increased age, prolonged length of stay, and duration of catheterization).

CONCLUSIONS

Our ensemble learning model demonstrated promising performance. Future work should continue to develop a more concise scoring tool based on machine learning models and prospectively examining the model in practical use, thus improving clinical outcomes.

Aspects of Prevention of Urinary Tract Infections Associated with Urinary Bladder Catheterisation and Their Implementation in Nursing Practice

In the case of the prevention of catheter-associated urinary tract infections (CAUTI) related to healthcare provision, high-quality and comprehensively provided nursing care is essential. Implementation of preventive strategies is based on recommended procedures, and the introduction of whole sets of measures has been shown to be effective. The objective of this research is to find out whether the providers of acute bed care have implemented the steps of CAUTI prevention, and specifically which measures leading to improved quality of care in the area of urinary infections are already in place. To determine this, we carried out quantitative research. Data were collected using a questionnaire-based investigation; we used two non-standardised and one standardised questionnaire, and the respondents were general nurses in management positions (n = 186). The results revealed that result-related CAUTI indicators are monitored by only one-third of the respondents, and records of catheterisation indication are not kept by 17.3% of general nurses. The results of the research showed deficiencies in the monitoring of CAUTI outcome and process indicators, and a weakness of the implemented preventive measures is the maintenance of catheterisation documentation. Periodic CAUTI prevention training is not implemented as recommended. It is positive that there are well-working teams of HAI prevention experts in hospitals.

A collaborative approach intended to reduce the duration of short term urinary catheters in adult patients at a tertiary care medical center also significantly reduced the duration of hospitalization

BACKGROUND

Urinary tract infections are the leading cause of nosocomial infections in the United States. The major contributing factor is the placement of indwelling urinary catheters.

METHODS

Following a chart review of adult patients hospitalized at a tertiary care medical center who required the use of a short-term (≤ 2 weeks) indwelling urinary catheter, a collaborative effort was initiated by an Infectious Diseases physician to develop protocols focused on the clinical service involved for the expeditious removal of short-term indwelling urinary catheters. The protocols relied in part on the standards of practice by pertinent medical/surgical subspecialty societies. Usage of urinary catheters and duration of hospitalization following implementation of the protocols was assessed.

RESULTS

Based on a multivariate analysis controlling for demographic variables, comorbidities, medical vs surgical service, and indication for the urinary catheterization, the median duration of catheterization was significantly reduced from 6.7 days to 3.6 days after the protocols were initiated (P < .001), and the median duration of hospitalization was significantly reduced from 9.5 days to 5.9 days (P < .001). No patient had to have the urinary catheter reinserted.

CONCLUSIONS

Development of collaborative protocols for the removal of short-term indwelling urinary catheters significantly reduced both the duration of catheterization and the duration of hospitalization.

A Clinical Nurse Specialist-Led Initiative to Reduce Catheter-Associated Urinary Tract Infection Rates Using a Best Practice Guideline

PURPOSE

The purpose of this clinical nurse specialist-led initiative was to reduce catheter-associated urinary tract infection rates to less than 1 infection per 1000 catheter days, to reduce catheter device utilization, and to improve staff adherence to documentation requirements on a traumatic brain injury rehabilitation unit.

DESCRIPTION OF THE PROJECT

Catheter-associated urinary tract infections are costly hospital-acquired infections increasing length of stay and morbidity for patients. Following an education intervention, a best practice initiative was implemented. Staff performance based on electronic health record documentation, infection rates, and device utilization were compared before and after a bundle of interventions including education, staff competency, simulation, and audits.

OUTCOMES

Catheter-associated urinary tract infection rates were reduced from 16.67 to 0 per 1000 catheter days and device utilization ratio from 0.122 to 0.056 per patient day. The unit maintained zero infections upon project completion. Following initiative implementation, documentation improved related to urinary catheter necessity, daily care interventions, patient education, and urine output.

CONCLUSION

This initiative resulted in reductions in device utilization and catheter infection rates, which were maintained following project completion. Adherence to documentation audit criteria also improved.

Optimized Silica-Binding Peptide-Mediated Delivery of Bactericidal Lysin Efficiently Prevents Staphylococcus aureus from Adhering to Device Surfaces

Staphylococcal-associated device-related infections (DRIs) represent a significant clinical challenge causing major medical and economic sequelae. Bacterial colonization, proliferation, and biofilm formation after adherence to surfaces of the indwelling device are probably the primary cause of DRIs. To address this issue, we incorporated constructs of silica-binding peptide (SiBP) with ClyF, an anti-staphylococcal lysin, into functionalized coatings to impart bactericidal activity against planktonic and sessile Staphylococcus aureus. An optimized construct, SiBP1-ClyF, exhibited improved thermostability and staphylolytic activity compared to its parental lysin ClyF. SiBP1-ClyF-functionalized coatings were efficient in killing MRSA strain N315 (>99.999% within 1 h) and preventing the growth of static and dynamic S. aureus biofilms on various surfaces, including siliconized glass, silicone-coated latex catheter, and silicone catheter. Additionally, SiBP1-ClyF-immobilized surfaces supported normal attachment and growth of mammalian cells. Although the recycling potential and long-term stability of lysin-immobilized surfaces are still affected by the fragility of biological protein molecules, the present study provides a generic strategy for efficient delivery of bactericidal lysin to solid surfaces, which serves as a new approach to prevent the growth of antibiotic-resistant microorganisms on surfaces in hospital settings and could be adapted for other target pathogens as well.

Gum acacia PEG iron oxide nanocomposite (GA-PEG-IONC) induced pharmacotherapeutic activity on the Las R gene expression of Pseudomonas aeruginosa and HOXB13 expression of prostate cancer (Pc 3) cell line. A green therapeutic approach of molecular mechanism inhibition

Among the diverse nanomaterials, polymer-based nanocomposites are gained more attention due to their high efficacy, target biological activities, biodegradability and biocompatibility-gum acacia (GA) - a polymer obtained from acacia trees-is considering the multifunctional nanocomposite synthesis. Distinctive Physico-chemical and biocompatibility properties of gum acacia are utilised to prepare a highly stable, biologically active, eco-friendly Nanocomposite. In this current investigation, gum acacia - poly ethylene glycol grafted iron oxide nanocomposite (GA-PEG-IONC) was synthesised by in situ green science principles. The synthesised Nanocomposite was evaluated against the molecular mechanism of urinary tract pathogenic bacterial strains and prostate cancer cells (Pc 3). Nanocomposite prepared in this examination exhibited notable structural, functional stability with nanoarchitecture which was affirmed by Fourier transform infrared spectroscopy (FTIR), electron microscopic studies, atomic force microscopy (AFM), vibrating sample magnetometric analysis (VSM) and X-ray diffraction (XRD), Synthesised Nanocomposite brought about notable antibacterial activity against urinary tract pathogenic strains by recording potential inhibitory effect on the expression of Las R gene. Inhibition of Las R gene expression reduced notable effect on biofilm development. Anticancer activity against prostate cancer cells (Pc3) was investigated by measurement of HOXB13 gene expression level. Inhibition of HOXB13 gene expression by the IONC brought about structural, functional changes. HOXB13 gene expression inhibition reveals a remarkable cytotoxic effect by recording decreased cell viability. Morphometric analysis by phase-contrast and DAPI fluorescence staining demonstrates that the Nanocomposite prompted cell morphology anomalies or apoptotic changes. Nanocomposite treatment brought about a good sign of Apoptosis by recording enhanced caspase 3 and 9 activities, DNA fragmentation and elevated reactive oxygen species generation (ROS). Hemocompatibility studies were carried out to determine the biocompatibility of the Nanocomposite. Spectrophotometric estimation of plasma haemoglobin, microscopic examination of whole blood cells shows the Nanocomposite was not inciting any indication of toxicity. These findings infer that IONC synthesised in the present study is the promising contender for a broad scope of biomedical applications, especially as an antibacterial and anticancer agent.

Implementation of a Nurse-Driven Asthma Pathway in the Pediatric Intensive Care Unit

Asthma is one of the most common conditions requiring admission to a pediatric intensive care unit. Dosing and weaning medications, particularly bronchodilators, are highly variable, and evidence-based weaning algorithms for clinicians are lacking in this setting.

METHODS

Patients admitted to a quaternary pediatric intensive care unit diagnosed with acute severe asthma were evaluated for time spent receiving continuous albuterol therapy, the length of stay in the intensive unit care unit, and the length of stay in the hospital. We developed an asthma pathway and continuous bronchodilator weaning algorithm to be used by bedside nurses. We then implemented two major Plan-Do-Study-Act cycles to facilitate the use of the pathway. They included implementing the algorithm and then integrating it as a clinical decision support tool in the electronic medical record. We used standard statistics and quality improvement methodology to analyze results.

RESULTS

One-hundred twenty-six patients met inclusion criteria during the study period, with 32 during baseline collection, 60 after weaning algorithm development and implementation, and 34 after clinical decision support implementation. Using quality improvement methodology, hours spent receiving continuous albuterol decreased from a mean of 43.6 to 28.6 hours after clinical decision support development. There were no differences in length of stay using standard statistics and QI methodology.

CONCLUSION

Protocolized asthma management in the intensive care unit setting utilizing a multidisciplinary approach and clinical decision support tools for bedside nursing can reduce time spent receiving continuous albuterol and may lead to improved patient outcomes.

Administration of indwelling urinary catheters in four Australian Hospitals: cost-effectiveness analysis of a multifaceted nurse-led intervention

BACKGROUND

Urinary catheters are useful among hospital patients for allowing urinary flows and preparing patients for surgery. However, urinary infections associated with catheters cause significant patient discomfort and burden hospital resources. A nurse led intervention aiming to reduce inpatient catheterisation rates was recently trialled among adult overnight patients in four New South Wales hospitals. It included: 'train-the trainer' workshops, site champions, compliance audits and promotional materials. This study is the 'in-trial' cost-effectiveness analysis, conducted from the perspective of the New South Wales Ministry of Health.

METHODS

The primary outcome variable was catheterisation rates. Catheterisation and procedure/treatment data were collected in three point prevalence patient surveys: pre-intervention (n = 1630), 4-months (n = 1677), and 9-months post-intervention (n = 1551). Intervention costs were based on trial records while labour costs were gathered from wage awards. Incremental cost effectiveness ratios were calculated for 4- and 9-months post-intervention and tested with non-parametric bootstrapping. Sensitivity scenarios recalculated results after adjusting costs and parameters.

RESULTS

The trial found reductions in catheterisations across the four hospitals between preintervention (12.0 % (10.4 - 13.5 %), n = 195) and the 4- (9.9 % (8.5 - 11.3 %), n = 166 ) and 9- months (10.2 % (8.7 - 11.7 %) n = 158) post-intervention points. The trend was statistically non-significant (p = 0.1). Only one diagnosed CAUTI case was observed across the surveys. However, statistically and clinically significant decreases in catheterisation rates occurred for medical and critical care wards, and among female patients and short-term catheterisations. Incremental cost effectiveness ratios at 4-months and 9-months post-intervention were $188 and $264. Bootstrapping found reductions in catheterisations at positive costs over at least 72 % of iterations. Sensitivity scenarios showed that cost effectiveness was most responsive to changes in catheterisation rates.

CONCLUSIONS

Analysis showed that the association between the intervention and changes in catheterisation rates was not statistically significant. However, the intervention resulted in statistically significant reductions for subgroups including among short-term catheterisations and female patients. Cost-effectiveness analysis showed that reductions in catheterisations were most likely achieved at positive cost.

Catheter-associated urinary tract infection

This guideline contains updated recommendations on the management and prevention of CAUTIs by the Urological Association of Asia and the Asian Association of Urinary Tract Infection and Sexually Transmitted Infection.

Catheter-Associated Urinary Tract Infections in the Adult Patient Group: A Qualitative Systematic Review on the Adopted Preventative and Interventional Protocols From the Literature

Catheter-associated urinary tract infections (CA-UTIs) are among the most common nosocomial infections acquired by patients in health care settings. A significant risk factor for CA-UTIs is the duration of catheterization. To summarize the current strategies and interventions in reducing urinary tract infections associated with urinary catheters, use and the need for re-catheterization on the rate of CA-UTIs, we performed a systematic review. A rapid evidence analysis was carried out in the Medline (via Ovid) and the Cochrane Library for the periods of January 2005 till April 2021. The main inclusion criterion required to be included in this review was symptomatic CA-UTI in adults as a primary or secondary outcome in all the included studies. Only randomized trials and systematic reviews were included, reviewed, evaluated, and abstracted data from the 1145 articles that met the inclusion criteria. A total of 1145 articles were identified, of which 59 studies that met the inclusion criteria were selected. Studies of relevance to CA-UTIs were based on: duration of catheterization, indication for catheterization, catheter types, UTI prophylaxis, educational proposals and approaches, and mixed policies and interventions. The duration of catheterization is the contributing risk factor for CA-UTI incidence; longer-term catheterization should only be undertaken where needed indications. The indications for catheterization should be based on individual base to base cases. The evidence for systemic prophylaxis instead of when clinically indicated is still equivocal. However, antibiotic-impregnated catheters reduce the risk of symptomatic CA-UTIs and bacteriuria and are more cost-effective than other impregnated catheter types. Antibiotic resistance, potential side effects and increased healthcare costs are potential disadvantages of implementing antibiotic prophylaxis. Multiple interventions and measures such as reducing the number of catheters in place, removing catheters at their earliest, clinically appropriate time, reducing the number of unnecessary catheters inserted, decrease antibiotic administration unless clinically needed, raising more awareness and provide training of nursing personnel on the latest guidelines, can effectively lower the incidence of CA-UTIs.

Knowledge, attitude and practice in relation to catheter-associated urinary tract infection (CAUTI) prevention: A cross-sectional study

BACKGROUND

Healthcare-associated infection (HAI) is one of the major threats to patients' safety besides being among the principal causes of patient morbidity and mortality. Catheter-associated urinary tract infection (CAUTI) is reported to be the most common HAI worldwide. CAUTI can be prevented with appropriate practice and care by healthcare personnel, especially nurses, who play the main role in urinary catheter care. Nurses' knowledge and attitude are considered to be important factors that influence their practice.

OBJECTIVES

To assess nurses' level of knowledge, attitude and perceived practice regarding CAUTI and its preventive measures.

METHODS

A cross-sectional design was adopted, and a self-administered questionnaire was used to collect data. Nurses from the medical and surgical inpatient wards of a tertiary teaching hospital in Malaysia were recruited in two stages using the stratified and simple random sampling methods. A total of 301 nurses participated. Descriptive analysis, an independent t test, ANOVA and hierarchical multiple regression were employed to analyse the data using SPSS software version 25. In addition, a STROBE checklist was used to report the results of this study.

RESULTS

Nurses were found to have good knowledge, a positive attitude and good perceived practice regarding CAUTI prevention. Nurses aged above 30 and who had more than ten years of experience reported higher knowledge levels. Knowledge was found to be positively correlated with attitude and perceived practice; however, attitude explained a higher variance in perceived practice of CAUTI prevention compared with knowledge.

CONCLUSION

Attitude was found to have a higher significant influence on perceived practice in this study. Educators need to emphasise the inculcation of a positive attitude among nurses rather than just knowledge for CAUTI prevention. Since this study assessed perceived practice, examining nurses' actual practice and its impact on patient outcomes is recommended in future studies.

Effects of Pharmacist-Led Clinical Pathway/Order Sets on Cancer Patients: A Systematic Review

Background: Pharmacist-led clinical pathways/order sets (PLCOs) were first applied for designated diseases and surgical operations, such as cancer. They were not used in pharmacotherapy until recently. After screening a large number of publications, we found that PLCOs were rarely accessible.

Objective: To evaluate the effects and the changes of relevant medical outcomes of PLCOs.

Methods: Articles from PubMed, Embase, Cochrane Library, China National Knowledge Infrastructure, Wanfang database, and China Biology Medicine disc (CBM) were systematically retrieved. Clinical research comparing cancer patients’ clinical effects with or without clinical pathway/order sets was performed. Two reviewers performed quality assessment, and the data were abstracted independently. A narrative synthesis of the extracted data was performed due to heterogeneity.

Results: Nine studies were identified, including six uncontrolled before–after studies and three case-series studies. The scopes of PLCOs of included research can be divided into two types, one focusing on chemotherapy agents and the other on the managements of chemotherapy-induced complications. The PLCOs shortened hospital length of stay, decreased initial antibiotic time intervals in patients with febrile neutropenia, reduced medication error incidence, and increased physicians’ adherence rate to clinical pathway/order sets. Moreover, three articles included economic effects showing positive savings on medication costs through PLCOs.

Conclusion: PLCOs can have beneficial effects on medication effectiveness, safety, and economic outcomes. Nevertheless, clinical pathway/order sets need to be further optimized and expanded to other clinical areas.

Accuracy of Measuring Bladder Volumes With Ultrasound and Bladder Scanning

BACKGROUND

Removal of urinary catheters depends on accurate noninvasive measurements of bladder volume. Patients with acute kidney injury often have low bladder volumes/ascites, possibly causing measurement inaccuracy.

OBJECTIVE

To evaluate the accuracy of bladder volumes measured with bladder scanning and 2-dimensional ultrasound (US) compared with urinary catheterization among different types of clinicians.

METHODS

Prospective correlational descriptive study of 73 adult critical care patients with low urine output receiving hemodialysis or unable to void. Bladder volumes were independently measured by (1) a physician and an advanced practice registered nurse using US, (2) an advanced practice registered nurse and a bedside nurse using bladder scanning, and (3) urinary catheterization (cath). Bland-Altman and χ2 analyses were conducted.

RESULTS

Mean (SD) cath volume was 171.7 (269.7) mL (range, 0-1100 mL). Abdominal fluid was observed in 28% of patients. Bias was -1.3 mL for US vs cath and 3.3 mL for bladder scanning vs cath. For patients with abdominal fluid and cath volume less than 150 mL, decisions to not catheterize patients were accurate more often when based on US measurements (97%-100%) than when based on bladder scanning measurements (86%-89%; P = .02). In patients with cath volume of 300 mL or more, decisions to catheterize patients were accurate more often when based on bladder scanning measurements (94%-100%) than when based on horizontal US measurements (50%-56%; P = .001).

CONCLUSIONS

Bladder volume can be measured accurately with bladder scanning or US, but abdominal fluid remains a confounding factor limiting accuracy of bladder scanning.

Reconsidering the nursing role in antimicrobial stewardship: a multisite qualitative interview study

OBJECTIVES

This study responds to calls for greater focus on nursing roles, and the need for nursing integration within the antimicrobial optimisation agenda. The objective of this study was to explore Australian hospital nurses' views on antimicrobial resistance and antimicrobial stewardship (AMS) in a hospital setting, in order to better understand the opportunities for and challenges to integration of nursing staff in antimicrobial optimisation within hospital settings.

DESIGN

Qualitative one-on-one, semistructured interviews. Interview transcripts were digitally audio-recorded and transcribed verbatim. Data were subject to thematic analysis supported by the framework approach and informed by sociological methods and theory.

SETTING

Four hospitals (three public and one private), across metropolitan, regional and remote areas, in two Australian states.

PARTICIPANTS

86 nurses (77 females, 9 males), from a range of hospital departments, at a range of career stages.

RESULTS

Findings were organised into three thematic domains: (1) the current peripheral role of nurses in AMS; (2) the importance of AMS as a collaborative effort, and current tensions around interprofessional roles and (3) how nurses can bolster antimicrobial optimisation within AMS and beyond.

CONCLUSION

Nursing staff are central to infection management within the hospital and are thus ideally located to enhance antibiotic optimisation and contribute to AMS governance. However, without increased interprofessional cooperation, education and integration in the AMS agenda, as well as addressing organisational/resource constraints in the hospital, the nursing role in stewardship will remain limited.

Catheter-Associated Urinary Tract Infection Reduction in a Pediatric Safety Engagement Network

BACKGROUND

Catheter-associated urinary tract infections (CAUTIs) are a leading cause of health care-associated infection. Catheter insertion bundles (IBs) and maintenance bundles (MBs) have been developed to prevent CAUTIs but have not been extensively validated for use in pediatric populations. We report the CAUTI prevention efforts of a large network of children's hospitals.

METHODS

Children's hospitals joined the Children's Hospitals' Solutions for Patient Safety engagement network from 2011 to 2017, using an open start time engagement approach, and elected to participate in CAUTI prevention efforts, with 26 submitting data initially and 128 at the end. CAUTI prevention recommendations were first released in May 2012, and IBs and MBs were released in May 2014. Hospitals reported on CAUTIs, patient-days, and urinary catheter-line days and tracked reliability to each bundle. For the network, run charts or control charts were used to plot CAUTI rates, urinary catheter use, and reliability to each bundle component.

RESULTS

After the introduction of the pediatric CAUTI IBs and MBs, CAUTI rates across the network decreased 61.6%, from 2.55 to 0.98 infections per 1000 catheter-line days. Centerline shifts occurred both before and after the 2015 Centers for Disease Control and Prevention CAUTI definition change. Urinary catheter use rates did not decline during the intervention period. Network reliability to the IBs and MBs increased to 95.4% and 86.9%, respectively.

CONCLUSIONS

IBs and MBs aimed at preventing CAUTIs were introduced across a large network of children's hospitals. Across the network, the rate of urinary tract infections among hospitalized children with indwelling urinary catheters decreased 61.6%.

An Examination of the Barriers to and Facilitators of Implementing Nurse-Driven Protocols to Remove Indwelling Urinary Catheters in Acute Care Hospitals

BACKGROUND

Urinary catheter nurse-driven protocols (UCNDPs) for removal of indwelling urinary catheters (IUCs) can potentially prevent catheter-associated urinary tract infections (CAUTIs). However, they are used inconsistently. The objective of this study was to examine the barriers to and facilitators of implementation of UCNDPs in acute care hospitals.

METHODS

Between September 2017 and January 2019, researchers interviewed 449 frontline staff (nurses, physicians), managers, and executives from 17 US hospitals to better understand their experiences implementing, using, and overseeing use of UCNDPs. Our semistructured interview guide included questions about management practices and policies regarding enactment of a UCNDP.

RESULTS

Although the features of UCNDPs differed across hospitals, the analysis revealed that hospitals experienced common issues related to implementing and consistently using UCNDPs as a result of three major barriers: (1) nurse deference to physicians, (2) physician push-back, and (3) miscommunication about IUC removal. Interviewees also described several important facilitators to help overcome these barriers: (1) training care team members to use the UCNDP, (2) discussing IUC necessity and UCNDP use during rounds, (3) reminding care team members to follow UCNDPs, and (4) developing buy-in for UCNDP use across the hospital.

CONCLUSION

Although UCNDPs are fundamental in efforts to reduce and prevent CAUTIs, hospitals can proactively support their implementation and use by developing the skills that care team members need to enact UCNDPs when patients meet the clinical indications for removal, and increasing awareness about the value and importance of such protocols for reducing CAUTIs and improving patient safety.

Catheter-Associated Urinary Tract Infections in Adult Patients

BACKGROUND

Urinary tract infections are among the more common types of nosocomial infection in Germany and are associated with catheters in more than 60% of cases. With increasing rates of antibiotic resistance worldwide, it is essential to distinguish catheter-associated asymptomatic bacteriuria from catheter-associated urinary tract infection (CA-UTI).

METHODS

This review is based on publications from January 2000 to March 2019 that were retrieved by a selective search in Medline. Randomized clinical trials and systematic reviews in which the occurrence of CA-UTI in adult patients was a primary or secondary endpoint were included in the analysis. Two authors of this review, working independently, selected the publications and extracted the data.

RESULTS

508 studies were identified and 69 publications were selected for analysis by the prospectively defined criteria. The studies that were included dealt with the following topics: need for catheterization, duration of catheterization, type of catheter, infection prophylaxis, education programs, and multiple interventions. The duration of catheterization is a determinative risk factor for CA-UTI. The indications for catheterization should be carefully considered in each case, and the catheter should be left in place for the shortest possible time. The available data on antibiotic prophylaxis do not permit any definitive conclusion, but they do show a small benefit from antibiotic-impregnated catheters and from systemic antibiotic prophylaxis.

CONCLUSION

Various measures, including careful consideration of the indication for catheterization, leaving catheters in place for the shortest possible time, and the training of nursing personnel, can effectively lower the incidence of CA-UTI. The eous in some respects, and thus no recommendations can be given on certain questions relevant to CA-UTI.

Using appropriateness criteria to identify opportunities to improve perioperative urinary catheter use

BACKGROUND

The Michigan Appropriate Perioperative (MAP) criteria provide guidance regarding urinary catheter use. For Category A (e.g., laparoscopic cholecystectomy), B (e.g., hemicolectomy), and C (e.g., abdominoperineal resection) procedures, recommendations are to avoid catheter, remove POD 0 or 1, and remove POD 1-4, respectively. We applied MAP criteria to statewide registry data to identify improvement targets.

METHODS

Retrospective cohort study of risk-adjusted catheter use and duration for appendectomy, cholecystectomy, and colorectal resections in 2014-2015 from 64 Michigan hospitals.

RESULTS

5.5% of 13,032 Category A cases used urinary catheters, including 26.9% of open appendectomies. 94.5% of 1,624 Category B cases used catheters (31.2% remained after POD 1). 98.3% of 700 Category C cases used catheters (4.6% remained POD5+). Variation in duration of use persisted after risk adjustment.

CONCLUSIONS

Perioperative urinary catheter use was appropriate for most simple abdominal procedures, but duration of use varied in all categories.

Urinary Catheter Coating Modifications: The Race against Catheter-Associated Infections

Urinary catheters are common medical devices, whose main function is to drain the bladder. Although they improve patients’ quality of life, catheter placement predisposes the patient to develop a catheter-associated urinary tract infection (CAUTI). The catheter is used by pathogens as a platform for colonization and biofilm formation, leading to bacteriuria and increasing the risk of developing secondary bloodstream infections. In an effort to prevent microbial colonization, several catheter modifications have been made ranging from introduction of antimicrobial compounds to antifouling coatings. In this review, we discuss the effectiveness of different coatings in preventing catheter colonization in vitro and in vivo, the challenges in fighting CAUTIs, and novel approaches targeting host–catheter–microbe interactions.

Implementation of a multifaceted nurse-led intervention to reduce indwelling urinary catheter use in four Australian hospitals: A pre- and postintervention study

AIMS AND OBJECTIVES

This study aimed to reduce indwelling urinary catheter (IDC) use and duration through implementation of a multifaceted "bundled" care intervention.

BACKGROUND

Indwelling urinary catheters present a risk for patients through the potential development of catheter-associated urinary tract infection (CAUTI), with duration of IDC a key risk factor. Catheter-associated urinary tract infection is considered preventable yet accounts for over a third of all hospital-acquired infections. The most effective CAUTI reduction strategy is to avoid IDC use where ever possible and to remove the IDC as early as appropriate.

DESIGN

A cluster-controlled pre- and poststudy at a facility level with a phased intervention implementation approach.

METHODS

A multifaceted intervention involving a "No CAUTI" catheter care bundle was implemented, in 4 acute-care hospitals, 2 in metropolitan and 2 in rural locations, in New South Wales, Australia. Indwelling urinary catheter point prevalence and duration data were collected at the bedside on 1,630 adult inpatients at preintervention and 1,677 and 1,551 at 4 and 9 months postintervention. This study is presented in line with the StaRI checklist (see Appendix S1).

RESULTS

A nonsignificant trend towards reduction in IDC prevalence was identified, from 12% preintervention to 10% of all inpatients at 4 and 9 months. Variability in preintervention IDC prevalence existed across hospitals (8%-16%). Variability in reduction was evident across hospitals at 4 months (between -2% and 4%) and 9 months (between 0%-8%). Hospitals with higher preintervention prevalence showed larger decreases, up to 50% when preintervention prevalence was 16%. Indwelling urinary catheter duration increased as more of the short-term IDC placements were avoided.

CONCLUSIONS

Implementation of a multifaceted intervention resulted in reduced IDC use in four acute-care hospitals in Australia. This result was not statistically significant but did reflect a positive trend of reduction. There was a significant reduction in short-term IDC use at 9 months postintervention.

RELEVANCE TO CLINICAL PRACTICE

Clinical nurse leaders can effectively implement change strategies that influence patient outcomes. Implementation of the evidence-based "No CAUTI" bundle increased awareness of appropriate indications and provided nurses with the tools to inform decision-making related to insertion and removal of IDCs in acute inpatient settings. Working in partnership with inpatients and the multidisciplinary team is essential in minimising acute-care IDC use.

Association between organizational characteristics and adequate pain management at the intensive care unit

PURPOSE

Half of the patients experience pain during their ICU stay which is known to influence their outcomes. Nurses and physicians encounter organizational barriers towards pain assessment and treatment. We aimed to evaluate the association between adequate pain management and nurse to patient ratio, bed occupancy rate, and fulltime presence of an intensivist.

MATERIALS AND METHODS

We performed unadjusted and case-mix adjusted mixed-effect logistic regression modeling on data from thirteen Dutch ICUs to investigate the association between ICU organizational characteristics and adequate pain management, i.e. patient-shift observations in which patients' pain was measured and acceptable, or unacceptable and normalized within 1 h. All ICU patients admitted between December 2017 and June 2018 were included, excluding patients who were delirious, comatose or had a Glasgow coma score < 8 at the first day of ICU admission.

RESULTS

Case-mix adjusted nurse to patient ratios of 0.70 to 0.80 and over 0.80 were significantly associated with adequate pain management (OR [95% confidence interval] of respectively 1.14 [1.07-1.21] and 1.16 [1.08-1.24]). Bed occupancy rate and intensivist presence showed no association.

CONCLUSION

Higher nurse to patient ratios increase the percentage of patients with adequate pain management especially in medical and mechanically ventilated patients.

What US hospitals are currently doing to prevent common device-associated infections: results from a national survey

BACKGROUND

Despite focused initiatives to reduce device-associated infection among hospitalised patients, the practices US hospitals are currently using are unknown. We thus used a national survey to ascertain the use of several established and novel practices to prevent device-associated infections.

METHODS

We mailed surveys to infection preventionists in a random sample of nearly 900 US acute care hospitals in 2017. Our survey asked about the use of practices to prevent three common device-associated infections: catheter-associated urinary tract infection (CAUTI), central line-associated bloodstream infection (CLABSI) and ventilator-associated pneumonia (VAP). Using sample weights, we estimated the percentage of hospitals reporting regular use of each practice. We also conducted multivariable regression to determine associations between selected hospital characteristics (eg, perceived support from leadership) and use of CAUTI, CLABSI and VAP prevention practices.

RESULTS

The response rate was 59%. Several practices are reportedly used in over 90% of US hospitals: aseptic technique during indwelling urethral catheter insertion and maintenance (to prevent CAUTI); maximum sterile barrier precautions during central catheter insertion and alcohol-containing chlorhexidine gluconate for insertion site antisepsis (to prevent CLABSI); and semirecumbent positioning of the patient (to prevent VAP). Antimicrobial devices are used in the minority of hospitals for these three device-associated infections.

CONCLUSIONS

We provide an updated snapshot of the practices US hospitals are currently using to prevent device-associated infections. Compared with previous studies using a similar design and questions, we found that the use of recommended practices increased in US hospitals, especially for CAUTI prevention.

Catheter-associated urinary tract infection: why do not we control this adverse event?

OBJECTIVE

To identify factors related to the occurrence of urinary tract infection associated with urinary catheter use.

METHOD

A longitudinal, retrospective cohort study carried out by analyzing the electronic medical records of patients admitted to an intensive care unit of a high-complexity hospital from July 2016 to June 2017. Demographic and clinical data were analyzed by descriptive and analytical analysis.

RESULTS

The incidence density of urinary tract infection related to urinary catheter use was 4.8 per 1000 catheters/day, the majority (80.6%) with no indication for catheter use, and there was no prescription for insertion and/or maintenance in 86.7%. The mean time between catheter insertion and infection diagnosis was 11.3 ± 6.3 days (6 to 28 days). Statistically significant factors (p < 0.001) related to urinary infection linked to catheter use were hospitalization time in the unit (16.7 ± 9 days), catheter permanence time (12.7 ± 6.9 days), and the use of antimicrobials in the intensive care unit (8.6 ± 6.3 days).

CONCLUSION

The association of indication absence and the record of the need for maintenance possibly potentiated the occurrence of urinary tract infection associated to catheter use.

Integrating bedside nurses into antibiotic stewardship: A practical approach

Nurses view patient safety as an essential component of their work and have reported a general interest in embracing an antibiotic steward role. However, antibiotic stewardship (AS) functions have not been formally integrated into nursing practice despite nurses' daily involvement in clinical activities that impact antibiotic decisions (e.g., obtaining specimens for cultures, blood drawing for therapeutic drug monitoring). Recommendations to expand AS programs to include bedside nurses are generating support at a national level, yet a practical guidance on how nurses can be involved in AS activities is lacking. In this review, we provide a framework identifying selected practices where nurses can improve antibiotic prescribing practices through appropriate obtainment of Clostridioides difficile tests, appropriate urine culturing practices, optimal antibiotic administration, accurate and detailed documentation of penicillin allergy histories and through the prompting of antibiotic time outs. We identify reported barriers to engagement of nurses in AS and offer potential solutions that include patient safety principles and quality improvement strategies that can be used to mitigate participation barriers. This review will assist AS leaders interested in advancing the contributions of nurses into their AS programs by discussing education, communication, improvement models, and workflow integration enhancements that strengthen systems to support nurses as valued partners in AS efforts.

Pathophysiology, Treatment, and Prevention of Catheter-Associated Urinary Tract Infection

Urinary tract infections (UTIs) are among the most common microbial infections in humans and represent a substantial burden on the health care system. UTIs can be uncomplicated, as when affecting healthy individuals, or complicated, when affecting individuals with compromised urodynamics and/or host defenses, such as those with a urinary catheter. There are clear differences between uncomplicated UTI and catheter-associated UTI (CAUTI) in clinical manifestations, causative organisms, and pathophysiology. Therefore, uncomplicated UTI and CAUTI cannot be approached similarly, or the risk of complications and treatment failure may increase. It is imperative to understand the key aspects of each condition to develop successful treatment options and improve patient outcomes. Here, we will review the epidemiology, pathogen prevalence, differential mechanisms used by uropathogens, and treatment and prevention of uncomplicated UTI and CAUTI.

Timing of complications following surgery for geriatric hip fractures

INTRODUCTION

Despite abundant literature present on complications following hip fracture surgery, few studies have focused on the timing of these complications.

MATERIALS AND METHODS

The 2015-2016 American College of Surgeons - National Surgical Quality Improvement Program database was queried for patients ≥65 years of age undergoing hip fracture surgery, due to trauma, using CPT-Codes for total hip arthroplasty (27130), Hemiarthroplasty (27125) and Open Reduction/Internal Fixation (ORIF) (27236, 27244, 27245). For each complication being studied, the median time to diagnosis was determined along with the interquartile range (IQR). Cox-regression analyses were used to assess complication timings between various surgeries.

RESULTS

A total of 31,738 were included in the final cohort. The median time of occurrence (days) for myocardial infarction was 2 [IQR 1-6], pneumonia 4 [IQR 2-12], stroke/CVA 3 [IQR 1-10], pulmonary embolism 5 [IQR 2-14], urinary tract infection (UTI) 8 [IQR 2-15], deep venous thrombosis (DVT) 9 [IQR 4-17], sepsis 11 [IQR 5-19], death 12 [IQR 6-20], superficial surgical site infection (SSI) 16 [IQR 12-22], deep SSI 23 [IQR 15-24] and organ/space SSI 19 [IQR 15-23]. Undergoing a THA vs. ORIF for hip fracture was associated a relatively early occurrence of pneumonia (day 3 [IQR 1-5.25]; p = 0.029) and urinary tract infection (day 4 [IQR 1-13]; p = 0.035) and a later occurrence of organ/space SSI (day 23.5 [IQR 19.5-26.75]; p = 0.002).

CONCLUSION

Orthopaedic trauma surgeons can utilize this data to optimize care strategies during the time-periods of highest risk to prevent complications from occurring early on in the course of post-operative care.
