The Ann Arbor Criteria for Appropriate Urinary Catheter Use in Hospitalized Medical Patients: Results Obtained by Using the RAND/UCLA Appropriateness Method

Impact of external female urinary catheter use on urine chemistry test results

BACKGROUND

We aimed to evaluate how urine chemistry tests are impacted by collection using a female external urinary catheter employing wicking and suction, to assess this catheter's potential as an alternative to transurethral catheters for collecting urine samples from incontinent patients.

METHODS

We obtained 50 random 40 mL refrigerated urine specimens from excess volume submitted to the Michigan Medicine Biochemical Laboratory. Specimens were split into a 10 mL "control" sample simulating voided urine, and a 30 mL paired "wicked" sample applied dropwise to and collected from a fresh PureWick system simulating collection from an incontinent patient. Each sample pair was tested for glucose, sodium, potassium, creatinine, urea, total protein, and derived ratios of sodium/creatinine, urea/creatinine, and protein/creatinine, then compared using Pearson correlation coefficients. Wicking materials were imaged via absorption contrast tomography on a laboratory X-ray microscope, to study the structure through which urine passes.

RESULTS

Control and wicked urine samples had very similar results for all chemical tests evaluated: strong Pearson correlation coefficients ranging from 0.955 (potassium) to 0.997 (glucose). Microscopic assessment of the amorphous wicking materials demonstrated an average pore spacing of 95.38 µm.

CONCLUSIONS

Common urine chemistry tests were unaltered by collection using the PureWick female external catheter system. This external device can be used to collect urine for chemistry tests as an alternative to transurethral catheters.

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.

Urinary Retention Evaluation and Catheterization Algorithm for Adult Inpatients

Importance

Acute urinary retention (UR) is common, yet variations in diagnosis and management can lead to inappropriate catheterization and harm.

Objective

To develop an algorithm for screening and management of UR among adult inpatients.

Design, Setting, and Participants

In this mixed-methods study using the RAND/UCLA Appropriateness Method and qualitative interviews, an 11-member multidisciplinary expert panel of nurses and physicians from across the US used a formal multi-round process from March to May 2015 to rate 107 clinical scenarios involving diagnosis and management of adult UR in postoperative and medical inpatients. The panel ratings informed the first algorithm draft. Semistructured interviews were conducted from October 2020 to May 2021 with 33 frontline clinicians-nurses and surgeons from 5 Michigan hospitals-to gather feedback and inform algorithm refinements.

Main Outcomes and Measures

Panelists categorized scenarios assessing when to use bladder scanners, catheterization at various scanned bladder volumes, and choice of catheterization modalities as appropriate, inappropriate, or uncertain. Next, qualitative methods were used to understand the perceived need, usability, and potential algorithm uses.

Results

The 11-member expert panel (10 men and 1 woman) used the RAND/UCLA Appropriateness Method to develop a UR algorithm including the following: (1) bladder scanners were preferred over catheterization for UR diagnosis in symptomatic patients or starting as soon as 3 hours since last void if asymptomatic, (2) bladder scanner volumes appropriate to prompt catheterization were 300 mL or greater in symptomatic patients and 500 mL or greater in asymptomatic patients, and (3) intermittent was preferred to indwelling catheterization for managing lower bladder volumes. Interview findings were organized into 3 domains (perceived need, feedback on algorithm, and implementation suggestions). The 33 frontline clinicians (9 men and 24 women) who reviewed the algorithm reported that an evidence-based protocol (1) was needed and could be helpful to clinicians, (2) should be simple and graphically appealing to improve rapid clinician review, and (3) should be integrated within the electronic medical record and prominently displayed in hospital units to increase awareness. The draft algorithm was iteratively refined based on stakeholder feedback.

Conclusions and Relevance

In this study using a systematic, multidisciplinary, evidence- and expert opinion-based approach, a UR evaluation and catheterization algorithm was developed to improve patient safety by increasing appropriate use of bladder scanners and catheterization. This algorithm addresses the need for practical guidance to manage UR among adult inpatients.

Reducing urinary tract infection rates in post-operative surgical patients: A quality improvement intervention

INTRODUCTION AND OBJECTIVES

The Scarborough Health Network joined the American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP) in fiscal year 2017-2018 with interest in tracking surgical outcomes in General and Vascular Surgery patients. Results of the ACS NSQIP program revealed poor outcomes in 30-day urinary tract infection (UTI) rates in this population group. Results were in the lowest quartile compared to peer hospitals. To improve patient care, SHN initiated a multi-pronged quality improvement plan (QIP).

METHODS

The QIP focused on several improvements: (1) clarify the current state and conduct a root cause analysis, (2) determine a plan to encourage early removal of catheters in post-surgical patients, (3) enhance team communication in the pre-operative, operative and post-operative care environments, and (4) improve education around UTI prevention and treatment.

RESULTS

This study demonstrates the success of the quality improvement plan to improve a peri-operative complication in surgical patients. By 2019, SHN saw a significant decrease in UTI rates, and became a top decile performer in ACS NSQIP.

CONCLUSIONS

This study demonstrates the feasibility and success of implementing a quality improvement project, and its methods can be adapted at other hospital sites to improve patient care.

Laboratory Tests, Bacterial Resistance, and Treatment Options in Adult Patients Hospitalized with a Suspected Urinary Tract Infection

Patients treated for systemic urinary tract infections commonly have nonspecific presentations, and the specificity of the results of the urinalysis and urine cultures is low. In the following narrative review, we will describe the widespread misuse of urine testing, and consider how to limit testing, the disutility of urine cultures, and the use of antibiotics in hospitalized adult patients. Automated dipstick testing is more precise and sensitive than the microscopic urinalysis which will result in false negative test results if ordered to confirm a positive dipstick test result. There is evidence that canceling urine cultures if the dipstick is negative (negative leukocyte esterase, and nitrite) is safe and helps prevent the overuse of urine cultures. Because of the side effects of introducing a urine catheter, for patients who cannot provide a urine sample, empiric antibiotic treatment should be considered as an alternative to culturing the urine if a trial of withholding antibiotic therapy is not an option. Treatment options that will decrease both narrower and wider spectrum antibiotic use include a period of watching and waiting before antibiotic therapy and empiric treatment with antibiotics that have resistance rates > 10%. Further studies are warranted to show the option that maximizes patient comfort and safety.

Urinary catheter placement and adverse urinary outcomes with a focus on elevated risk in men with indwelling Foley catheters

BACKGROUND

Prior studies indicated a link between urinary catheter use and urinary complications, highlighting the need for comprehensive, gender-specific investigations. This study explored the association through a national retrospective cohort, emphasizing gender disparities and long-term outcomes.

METHODS

Our study utilized data from the entire population covered by Taiwan's National Health Insurance Research Database from 2000 to 2017. We included 148,304 patients who had undergone Foley catheter placement and their propensity-scores matched controls in the study. We evaluated urinary complications, which encompassed urinary tract cancer, urolithiasis, urethral stricture, obstructive uropathy, reflux uropathy, fistula, diverticulum, caruncle, false passage, prolapsed urethral mucosa, urinary tract rupture, and urinary tract infection. These were assessed using the Fine and Gray sub-distribution proportional hazards model to compare between the Foley and non-Foley groups. Sensitivity analyses were conducted with different matching ratios.

RESULTS

In the study, the non-Foley group presented a marginally higher mean age (75.24 ± 10.47 years) than the Foley group (74.09 ± 10.47 years). The mean duration of Foley catheterization was 6.1 ± 4.19 years. Men with Foley catheterization exhibited the highest adjusted sub-distribution hazard ratios for urinary tract cancer (6.57, 95% CI: 5.85-7.37), followed by women with Foley catheterization (4.48, 95% CI: 3.98-5.05), and men without catheterization (1.58, 95% CI: 1.39-1.8) in comparison with women without the procedure. Furthermore, men with Foley catheterization were found to be at the greatest risk for complications such as urolithiasis, urethral stricture, obstructive and reflux uropathy, fistula, diverticulum, caruncle, false passage, prolapsed urethral mucosa, and urinary tract rupture. Conversely, women with urinary catheterization were most susceptible to urinary tract infections.

CONCLUSIONS

The evidence confirms that urinary catheterization significantly increases urinary complications, particularly among men. Our study underscores the crucial need for healthcare providers to carefully evaluate the necessity of catheterization, aim to shorten its duration whenever feasible, and strictly adhere to established protocols to minimize complications.

A comprehensive status update on modification of foley catheter to combat catheter-associated urinary tract infections and microbial biofilms

Present-day healthcare employs several types of invasive devices, including urinary catheters, to improve medical wellness, the clinical outcome of disease, and the quality of patient life. Among urinary catheters, the Foley catheter is most commonly used in patients for bladder drainage and collection of urine. Although such devices are very useful for patients who cannot empty their bladder for various reasons, they also expose patients to catheter-associated urinary tract infections (CAUTIs). Catheter provides an ideal surface for bacterial colonization and biofilm formation, resulting in persistent bacterial infection and severe complications. Hence, rigorous efforts have been made to develop catheters that harbour antimicrobial and anti-fouling properties to resist colonization by bacterial pathogens. In this regard, catheter modification by surface functionalization, impregnation, blending, or coating with antibiotics, bioactive compounds, and nanoformulations have proved to be effective in controlling biofilm formation. This review attempts to illustrate the complications associated with indwelling Foley catheters, primarily focussing on challenges in fighting CAUTI, catheter colonization, and biofilm formation. In this review, we also collate scientific literature on catheter modification using antibiotics, plant bioactive components, bacteriophages, nanoparticles, and studies demonstrating their efficacy through in vitro and in vivo testing.

Healthcare workers' compliance with the catheter associated urinary tract infection prevention guidelines: an observational study in Yemen

BACKGROUND

Catheter-associated urinary tract infection is a global problem but it can be prevented with the appropriate implementation of evidence-based guidelines. This study was conducted to assess the level of compliance of healthcare workers with the catheter-associated urinary tract infection prevention guidelines during the insertion of a urinary catheter.

METHODS

An observational study using a descriptive cross-sectional design was conducted at Sana'a City hospitals, Yemen. All the nurses and physicians from the governmental, teaching, and private hospitals were eligible to participate in the study. The data collection was performed through convenience sampling from March 2020 to December 2020, using a structured observational checklist prepared specifically for this study.

RESULTS

The majority of the urinary catheter insertions were performed by nurses. There were no written policy or procedures for an urinary catheter insertion and no in-service education or training departments in the majority of the hospitals. The overall mean score of compliance was 7.31 of 10. About 71% of the healthcare workers had a high or acceptable level of compliance and 29% had an unsafe level of compliance. Compliance was low for maintaining aseptic technique throughout the insertion procedure, using a single use packet of lubricant jelly, performing hand hygiene immediately before insertion, and securing the urinary catheter once inserted. Factors affecting the healthcare workers compliance were gender, the working ward/unit of the healthcare workers, the availability of a written policy/procedure and a department or unit for in-service education.

CONCLUSION

Yemeni healthcare workers' overall compliance was acceptable but it was unsafe in several critical measures. There is an urgent need for developing, implementing, and monitoring national guidelines and institutional policy and procedures for catheter-associated urinary tract infection prevention. Periodical in-service education and training programs and adequate access to the necessary materials and supplies are paramount.

What US hospitals are doing to prevent common device-associated infections during the coronavirus disease 2019 (COVID-19) pandemic: Results from a national survey in the United States

OBJECTIVE

The ways that device-associated infection prevention practices changed during the coronavirus disease 2019 (COVID-19) pandemic remain unknown. We collected data mid-pandemic to assess the use of several infection prevention practices and for comparison with historical data.

DESIGN

Repeated cross-sectional survey.

SETTING

US acute-care hospitals.

PARTICIPANTS

Infection preventionists.

METHODS

We surveyed infection preventionists from a national random sample of 881 US acute-care hospitals in 2021 to estimate the current use of practices to prevent catheter-associated urinary tract infection (CAUTI), central line-associated bloodstream infection (CLABSI), and ventilator-associated events (VAE). We compared the 2021 results with those from surveys occurring every 4 years since 2005.

RESULTS

The 2021 survey response rate was 47%; previous survey response rates ranged from 59% to 72%. Regular use of most practices to prevent CLABSI (chlorhexidine gluconate for site antisepsis, 99.0%, and maximum sterile barrier precautions, 98.7%) and VAE (semirecumbent positioning, 93.4%, and sedation vacation, 85.8%) continued to increase or plateaued in 2021. Conversely, use of several CAUTI prevention practices (portable bladder ultrasound scanner, 65.6%; catheter reminders or nurse-initiated discontinuation, 66.3%; and intermittent catheterization, 37.3%) was lower in 2021, with a significant decrease for some practices compared to 2017 (P ≤ .02 for all comparisons). In 2021, 42.1% of hospitals reported regular use of the newer external urinary collection devices for women.

CONCLUSIONS

Although regular use of CLABSI and VAE preventive practices continued to increase (or plateaued), use of several CAUTI preventive practices decreased during the COVID-19 pandemic. Structural issues relating to care during the pandemic may have contributed to a decrease in device-associated infection prevention practices.

Risk factors associated with pressure ulcer recurrence after reconstruction: Analysis of a national database

In this study, we sought to clarify the patient traits and comorbidities that are associated with pressure injury recurrence following pressure injury reconstruction. An insurance claims database, PearlDiver, was used to conduct a retrospective cohort study. The two cohorts included patients who underwent pressure injury reconstruction without recurrence and patients who experienced recurrence with subsequent reconstruction. Multiple logistic regression analysis was used to identify risk factors for recurrence after reconstruction. Recurrence was associated with hypoalbuminemia (p < 0.05), paraplegia (p < 0.05), and osteomyelitis (p < 0.05). In patients with osteomyelitis, primary closure was associated with recurrence (p < 0.05) while flap reconstruction was not (p > 0.05). Osteomyelitis was not associated with recurrence after flap reconstruction. Prior to reconstruction, patients with osteomyelitis and hypoalbuminemia should have their nutrition and infection optimised.

Consensus Guidelines for Perioperative Care for Emergency Laparotomy Enhanced Recovery After Surgery (ERAS®) Society Recommendations Part 2-Emergency Laparotomy: Intra- and Postoperative Care

BACKGROUND

This is Part 2 of the first consensus guidelines for optimal care of patients undergoing emergency laparotomy (EL) using an Enhanced Recovery After Surgery (ERAS) approach. This paper addresses intra- and postoperative aspects of care.

METHODS

Experts in aspects of management of high-risk and emergency general surgical patients were invited to contribute by the International ERAS® Society. PubMed, Cochrane, Embase, and Medline database searches were performed for ERAS elements and relevant specific topics. Studies on each item were selected with particular attention to randomized clinical trials, systematic reviews, meta-analyses, and large cohort studies and reviewed and graded using the Grading of Recommendations, Assessment, Development and Evaluation (GRADE) system. Recommendations were made on the best level of evidence, or extrapolation from studies on elective patients when appropriate. A modified Delphi method was used to validate final recommendations. Some ERAS® components covered in other guideline papers are outlined only briefly, with the bulk of the text focusing on key areas pertaining specifically to EL.

RESULTS

Twenty-three components of intraoperative and postoperative care were defined. Consensus was reached after three rounds of a modified Delphi Process.

CONCLUSIONS

These guidelines are based on best available evidence for an ERAS® approach to patients undergoing EL. These guidelines are not exhaustive but pull together evidence on important components of care for this high-risk patient population. As much of the evidence is extrapolated from elective surgery or emergency general surgery (not specifically laparotomy), many of the components need further evaluation in future studies.

Incorporating Expected Outcomes Into Clinical Decision-Making for Total Knee Arthroplasty

OBJECTIVE

Expected outcomes (e.g., expected survivorship after a cancer treatment) have improved decision-making around treatment options in many clinical fields. Our objective was to evaluate the effect of expected values of 3 widely available total knee arthroplasty (TKA) outcomes (risk of serious complications, time to revision, and improvement in pain and function at 2 years after surgery) on clinical recommendation of TKA.

METHODS

The RAND/University of California Los Angeles appropriateness criteria method was used to evaluate the role of the 3 expected outcomes in clinical recommendation of TKA. The expected outcomes were added to 5 established preoperative factors from the modified Escobar appropriateness criteria. The 8 indication factors were used to develop 279 clinical scenarios, and a panel of 9 clinicians rated the appropriateness of TKA for each scenario as inappropriate, inconclusive, and appropriate. Classification tree analysis was applied to these ratings to identify the most influential of the 8 factors in discriminating TKA appropriateness classifications.

RESULTS

Ratings for the 279 appropriateness scenarios deemed 34.4% of the scenarios as appropriate, 40.1% as inconclusive, and 25.5% as inappropriate. Classification tree analyses showed that expected improvement in pain and function and expected time to revision were the most influential factors that discriminated among the TKA appropriateness classification categories.

CONCLUSION

Our results showed that clinicians would use expected postoperative outcome factors in determining appropriateness for TKA. These results call for further work in this area to incorporate estimates of expected pain/function and revision outcomes into clinical practice to improve decision-making for TKA.

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.

Development and evaluation of a structured guide to assess the preventability of hospital-onset bacteremia and fungemia

OBJECTIVE

To assess preventability of hospital-onset bacteremia and fungemia (HOB), we developed and evaluated a structured rating guide accounting for intrinsic patient and extrinsic healthcare-related risks.

DESIGN

HOB preventability rating guide was compared against a reference standard expert panel.

PARTICIPANTS

A 10-member panel of clinical experts was assembled as the standard of preventability assessment, and 2 physician reviewers applied the rating guide for comparison.

METHODS

The expert panel independently rated 82 hypothetical HOB scenarios using a 6-point Likert scale collapsed into 3 categories: preventable, uncertain, or not preventable. Consensus was defined as concurrence on the same category among ≥70% experts. Scenarios without consensus were deliberated and followed by a second round of rating.Two reviewers independently applied the rating guide to adjudicate the same 82 scenarios in 2 rounds, with interim revisions. Interrater reliability was evaluated using the κ (kappa) statistic.

RESULTS

Expert panel consensus criteria were met for 52 scenarios (63%) after 2 rounds.After 2 rounds, guide-based rating matched expert panel consensus in 40 of 52 (77%) and 39 of 52 (75%) cases for reviewers 1 and 2, respectively. Agreement rates between the 2 reviewers were 84% overall (κ, 0.76; 95% confidence interval [CI], 0.64-0.88]) and 87% (κ, 0.79; 95% CI, 0.65-0.94) for the 52 scenarios with expert consensus.

CONCLUSIONS

Preventability ratings of HOB scenarios by 2 reviewers using a rating guide matched expert consensus in most cases with moderately high interreviewer reliability. Although diversity of expert opinions and uncertainty of preventability merit further exploration, this is a step toward standardized assessment of HOB preventability.

Planning and Reporting Effective Web-Based RAND/UCLA Appropriateness Method Panels: Literature Review and Preliminary Recommendations

BACKGROUND

The RAND/UCLA Appropriateness Method (RAM), a variant of the Delphi Method, was developed to synthesize existing evidence and elicit the clinical judgement of medical experts on the appropriate treatment of specific clinical presentations. Technological advances now allow researchers to conduct expert panels on the internet, offering a cost-effective and convenient alternative to the traditional RAM. For example, the Department of Veterans Affairs recently used a web-based RAM to validate clinical recommendations for de-intensifying routine primary care services. A substantial literature describes and tests various aspects of the traditional RAM in health research; yet we know comparatively less about how researchers implement web-based expert panels.

OBJECTIVE

The objectives of this study are twofold: (1) to understand how the web-based RAM process is currently used and reported in health research and (2) to provide preliminary reporting guidance for researchers to improve the transparency and reproducibility of reporting practices.

METHODS

The PubMed database was searched to identify studies published between 2009 and 2019 that used a web-based RAM to measure the appropriateness of medical care. Methodological data from each article were abstracted. The following categories were assessed: composition and characteristics of the web-based expert panels, characteristics of panel procedures, results, and panel satisfaction and engagement.

RESULTS

Of the 12 studies meeting the eligibility criteria and reviewed, only 42% (5/12) implemented the full RAM process with the remaining studies opting for a partial approach. Among those studies reporting, the median number of participants at first rating was 42. While 92% (11/12) of studies involved clinicians, 50% (6/12) involved multiple stakeholder types. Our review revealed that the studies failed to report on critical aspects of the RAM process. For example, no studies reported response rates with the denominator of previous rounds, 42% (5/12) did not provide panelists with feedback between rating periods, 50% (6/12) either did not have or did not report on the panel discussion period, and 25% (3/12) did not report on quality measures to assess aspects of the panel process (eg, satisfaction with the process).

CONCLUSIONS

Conducting web-based RAM panels will continue to be an appealing option for researchers seeking a safe, efficient, and democratic process of expert agreement. Our literature review uncovered inconsistent reporting frameworks and insufficient detail to evaluate study outcomes. We provide preliminary recommendations for reporting that are both timely and important for producing replicable, high-quality findings. The need for reporting standards is especially critical given that more people may prefer to participate in web-based rather than in-person panels due to the ongoing COVID-19 pandemic.

Effectiveness and safety of a program for appropriate urinary catheter use in stroke care: A multicenter prospective study

OBJECTIVES

Since patients with stroke frequently develop bladder dysfunction, a careful approach is required to reduce unnecessary indwelling urinary catheter (IUC) for preventing catheter-associated urinary tract infection (CAUTI). This study aimed to assess the effectiveness and safety of a program to promote appropriate IUC use in stroke care.

METHODS

We conducted a prospective interrupted time series study in three tertiary care hospitals in Japan. Adult patients with acute stroke were eligible. The study consisted of three phases: baseline, education and implementation. Our program included an assessment of IUC indications, educational meetings among healthcare professionals, reminders for removal of inappropriate IUC and a urinary retention protocol. The primary outcome was the proportion of inappropriate IUC use to assess effectiveness. The device utilization ratio and incidence of CAUTI were examined to assess effectiveness, and incidences of urinary retention and all symptomatic urinary tract infection (UTI) were examined to assess safety.

RESULTS

Among 976 patients who met the inclusion criteria, 738 were analysed. Inappropriate IUC use decreased from 50.1% in the baseline phase to 22.5% in the implementation phase (absolute risk reduction in interrupted time series analysis 42.4% [95% confidence interval, 19.2%-65.6%]). The device utilization ratio decreased from 0.302 to 0.194 (p < 0.001), whereas CAUTI did not change significantly (from 8.81 to 8.28 per 1000 catheter-days; incidence rate ratio 0.95 [0.44-1.94]). All symptomatic UTI decreased from 9.5% to 4.9% (p = 0.015), with no increase in urinary retention.

CONCLUSIONS

Our program improved the appropriateness of IUC use in stroke care while ensuring safety.

A novel intervention to reduce noninfectious and infectious complications associated with indwelling urethral catheters in hospitalized older patients: a quasi-experimental study

BACKGROUND

Indwelling urethral catheters are widely used in clinical settings. Catheter-associated urinary tract infection has been recognized as a common adverse event in older patients. However, noninfectious complications are almost 5 times as common as infectious complications, and insufficient attention has been given to noninfectious complications. Given this importance, a novel intervention related to removing unnecessary catheters in a timely manner to promote, after removal, the recovery of self-voiding function is herein developed to reduce infectious and noninfectious complications associated with indwelling urethral catheters in hospitalized older patients.

METHODS

A quasi-experimental study design was adopted. Patients aged 65 and older who had a urinary catheter placed within 24 h of hospital admission were included. All patients were allocated into either an intervention group, in which the novel intervention developed in the study was implemented, or a control group, who received care as usual. The outcomes of this study were to evaluate whether the novel intervention reduced the incidence of the following: catheter-associated urinary tract infections, catheter-associated noninfectious complications, decline in activities of daily living, and new nursing home admissions.

RESULTS

Of 106 hospitalized older patients who consented to participate, 92 completed follow-up until discharge, including 49 in the control group and 43 in the intervention group. The patients in the intervention group were significantly older than those in the control group [83.72 ± 9.18 vs. 80.26 ± 7.66, p = 0.038], and no differences were found between the groups in other demographics or present health conditions. Multivariable logistic regression analysis showed that the control group was more likely to develop noninfectious complications [adjusted odds ratio: 3.01, 95% confidence interval: 1.32-6.81] and a decline in ADLs [adjusted odds ratio: 11.20, 95% confidence interval: 3.68-34.00].

CONCLUSIONS

A novel intervention can be effective as a means of reducing noninfectious complications associated with indwelling urethral catheters in hospitalized older patients. This approach will help to standardize urethral catheter care, and it highlights the fact that health care professionals can play a crucial role in preventing harm from urethral catheters.

Inappropriate urinary catheterisation: a review of the prevalence, risk factors and measures to reduce incidence

Urinary tract infections (UTIs) comprise the second most common type of healthcare-associated infections, with up to 80% of UTIs caused by indwelling urinary catheters. Current research suggests that the best way to prevent catheter-associated UTIs (CAUTIs) is to reduce unnecessary catheterisation. Few reviews have focused on the prevalence, risk factors and preventive measures for inappropriate catheterisation. This article, consequently, sought to evaluate the current evidence on the prevalence, risk factors and measures that can be taken to prevent inappropriate urinary catheterisation.

An Adaptation of the RAND/UCLA Modified Delphi Panel Method in the Time of COVID-19

The RAND/UCLA modified Delphi panel method is a formal group consensus process that systematically and quantitatively combines expert opinion and evidence by asking panelists to rate, discuss, then re-rate items. The method has been used to develop medical society guidelines, other clinical practice guidelines, disease classification systems, research agendas, and quality improvement interventions. Traditionally, a group of experts meet in person to discuss results of a first-round survey. After the meeting, experts complete a second-round survey used to develop areas of consensus. During the COVID-19 pandemic, this aspect of the method was not possible. As such, we have adapted the method to conduct virtual RAND/UCLA modified Delphi panels. In this study, we present a targeted literature review to describe and summarize the existing evidence on the RAND/UCLA modified Delphi panel method and outline our adaptation for conducting these panels virtually. Transitioning from in-person to virtual meetings was not without challenges, but there have also been unexpected advantages. The method we describe here can be a cost-effective and efficient alternative for researchers and clinicians.

Real world utilization of nurse-driven urinary catheter removal protocol in patients with epidural pain catheters

BACKGROUND

Surgeons use indwelling bladder catheters (IBCs) to avoid urinary retention in patients with epidural analgesic catheters. Reduction of IBC-days is associated with improved catheter-associated urinary tract infection rates (CAUTI). This study investigates real world application of a Nurse-Driven Catheter Removal Protocol (NDCRP) to reduce IBC-days in this patient population.

METHODS

Patients with epidural catheters and IBC were targeted for IBC removal on post-operative day 1 (POD1). Patients were followed for application of the NDCRP, catheterization need, IBC re-anchoring, and complications.

RESULTS

One hundred and thirty-three patients had IBCs removed on POD1 (Protocol Group) and 50 patients did not (Non-Protocol Group). There was a reduction in IBC-days in the Protocol Group despite incomplete adherence to the NDCRP (1.55 days vs 4.64 days; P < .001). Ninety-three patients (70%) were able to spontaneously void after early IBC removal. Fourteen patients (11%) were able to spontaneously void after serial in-and-out catheterization (I/O). No significant difference in re-anchoring was found between the protocol and non-protocol groups (26 vs 4 patients; P = .09).

CONCLUSIONS

Early removal of IBCs (POD1) in patients with epidural catheters with the assistance of an NDCRP is a safe and successful strategy to reduce IBC-days in the hospital.

Prevalence and appropriateness of indwelling urinary catheters in Japanese hospital wards: a multicenter point prevalence study

BACKGROUND

Indwelling urinary catheters are commonly used in hospitalized patients, which can lead to the development of urinary catheter complications, including catheter-associated urinary tract infection (CAUTI). Limited reports on the appropriateness of urinary catheter use exist in Japan. This study investigated the prevalence and appropriateness of indwelling urinary catheters, and the incidence of CAUTI in non-intensive care unit (non-ICU) wards in Japanese hospitals.

METHODS

This prospective observational study was conducted in 7 non-ICU wards from 6 hospitals in Japan from October 2017 to June 2018. At each hospital the study teams evaluated urinary catheter prevalence through in-person bedside evaluation for at least 5 days of each week for 3 months. Catheter associated urinary tract infection (CAUTI) incidence and appropriateness of catheter use was collected via chart review.

RESULTS

We assessed 710 catheter-days over 5528 patient-days. The mean prevalence of indwelling urinary catheter use in participating wards was 13% (range: 5% to 19%), while the mean incidence of CAUTI was 9.86 per 1000 catheter-days (range: 0 to 33.90). Approximately 66% of the urinary catheter days assessed had an appropriate indication for use (range: 17% to 81%). A physician's order for catheter placement was present in only 10% of catheterized patients.

CONCLUSION

This multicenter study provides epidemiological information about the appropriate use of urinary catheters in Japanese non-ICU wards. A multimodal intervention may help improve the appropriate use of urinary catheters.

Clinical Significance of Increasing Pressure Curve's Slope When Injecting Ultrasound Contrast Agent During Evaluation of Fallopian Tubal Patency

OBJECTIVE

To explore the association between Fallopian tubal patency and the slope of the increasing pressure curve for ultrasound contrast agent.

MATERIALS AND METHODS

A total of 136 patients underwent transvaginal 4-dimensional hysterosalpingo-contrast sonography (TVS 4D HyCoSy) between August 2015 and January 2016. We divided the patients into 3 groups according to different Fallopian tubal patency status: 71 patients (48.97%) in bilateral tubal patency group, 45 (31.03%) in unilateral tubal patency group, and 20 in bilateral tubal nonpatent group. The ultrasound contrast agent was injected and the pressure curve was recorded automatically in real time using a liquid-injecting machine that traces it as a pressure curve. The slopes of the different groups are compared through independent sample t test.

RESULTS

The slopes of the 3 groups were 1.242 ± 0.572, 1.472 ± 0.638, and 2.068 ± 1.236 kPa/s. A correlation was observed between the slope of the increasing pressure curve and tubal patency (R = 0.287, P < .05). The slopes differed significantly between the bilateral tubal patency group and bilateral tubal nonpatent group (P = .001) and between the unilateral tubal patency group and bilateral tubal nonpatent group (P = .012). However, the difference between the bilateral tubal patency and unilateral tubal patency groups was not significant (P = .266).

CONCLUSION

The increase of the injecting pressure curve's slope for contrast agent during 4D HyCoSy is associated with the nonpatent degree of the tube. This condition can be used as an objective index of tubal patency and can be a reference in diagnosis and treatment.

Current in-hospital management for patients with tuberculosis in a high-income country: a retrospective cohort study

OBJECTIVES

In Japan, most cases of tuberculosis (TB) occur among individuals aged 65 years or older. However, data on in-hospital adverse events (AEs) associated with TB management, especially in high-income nations with an ageing population, are scarce. The present study aimed to scrutinize the current TB unit practices, incidence of in-hospital AEs and predictors of in-hospital mortality.

METHODS

This retrospective cohort study was conducted at a tertiary care centre in Tokyo, Japan from 2012 to 2017. Inpatients with the diagnosis of TB and aged >18 years were included. Quality of in-hospital care and factors associated with in-hospital mortality were investigated using multivariate logistic regression analysis.

RESULTS

In total, 448 patients were enrolled. The in-hospital mortality rate was 16.7% (75/448). Miliary/disseminated TB was common (59/448, 13.2%), especially in those who died (17/75, 22.7%). Factors independently associated with in-hospital mortality were a low Karnofsky performance status score on admission (score: 40-10, adjusted odds ratio (aOR) 25.65, 95% CI 5.63-116.92 and score: 70-50, aOR 9.47, 95% CI 2.07-43.3), age over 89 years (aOR 3.68, 95% CI 1.08-12.46), Charlson Co-morbidity Index >5 (aOR 3.56, 95% CI 1.37-9.21), development of any health-care-associated infection (aOR 2.95, 95% CI 1.35-6.41), and development of any drug-related AE leading to discontinuation of anti-TB agents (seven patients were unable to resume treatment with anti-TB agents before death) (aOR 2.29, 95% CI 1.02-5.11).

CONCLUSIONS

In-hospital AEs (i.e. health-care-associated infection and drug-related AEs), as well as patient-related variables, were associated with in-hospital mortality among TB patients.

A Novel Risk Prediction Model to Triage Difficult Urethral Catheterizations

OBJECTIVE

To construct a risk prediction model to identify cases of difficult urethral catheterizations (DUC) in order to prevent complications from improper placement.

MATERIALS AND METHODS

Using a single-institution database of urologic consults for Foley catheterizations from June 2016 to January 2020, a model to predict DUC in male patients was constructed. DUC was defined as requiring the use of a guidewire, cystoscopy, urethral dilation, and/or suprapubic tube (SPT) placement, while a simple Foley was defined as an uncomplicated placement of a regular or coudé catheter. A final model to predict DUC was constructed using multivariable logistic regression and internally validated using bootstrap statistics.

RESULTS

A total of 841 consults were identified, with 181 (21.5%) classified as a DUC. On multivariable regression, patient-specific factors as overweight BMI (OR: 1.71; P = .014), urethral stricture disease (OR: 7.38; P < .001), BPH surgery (OR: 2.47; P < .001), radical prostatectomy (OR: 4.32; P = .001), and genitourinary (GU) prosthetic implants (OR: 3.44; P = .046) were associated with DUC. Situational factors such as blood at the meatus (OR: 2.40; P < .001), and consulting team (eg, surgery OR: 4.82; P < .001) were also significant. Bootstrap analysis of the final model demonstrated good overall accuracy (predictive accuracy: 75%).

CONCLUSION

This model is a promising tool to help providers identify patients who likely require catheterization by a urologist and potentially reduce catheterization-related complications. The high rate of uncomplicated catheterizations also highlights the need for continuing education amongst healthcare professionals. External validation and application to the initial Foley encounter will shed light on its overall utility.

How common are indwelling devices in hospitalized adults? A contemporary point prevalence study in a tertiary care hospital

BACKGROUND

Healthcare associated infections are associated with indwelling devices. Yet, data regarding prevalence of indwelling devices in noncritically ill hospitalized patients remains scant.

METHODS

Adult, noncritically ill patients on general care, telemetry, and surgical floors at our quaternary care hospital were surveyed on 2 separate days. Data regarding presence of indwelling vascular, urinary, and gastrointestinal devices, as well as nurse to patient ratio on each unit were collected.

RESULTS

There were 1,229 devices observed among the 857 patients surveyed across 2 days. Of the surveyed patients, 780 (91.0%) had at least 1 indwelling device. Among all devices, intravenous catheters were the most common (90.1%), followed by gastrointestinal devices (12.8%) and urinary catheters (10.2%). The most prevalent device was peripheral intravenous catheters. The median nurse to patient ratio was 3 patients to 1 nurse; no difference in nurse to patient ratio based on the number of devices present was observed.

CONCLUSIONS

Indwelling device use appears highly prevalent in general care settings and variation among devices is common. Healthcare associated infections prevention strategies targeting these devices are necessary.

Appropriateness of Antibiotics Use and Associated Factors in Hospitalized Patients at University of Gondar Specialized Hospital, Amhara, Ethiopia: Prospective Follow-up Study

Background:

Appropriate antibiotic use means that the patient receives the appropriate drug at adequate doses and duration for a susceptible pathogen. This improves the effectiveness of antibiotic therapy and prevents the emergence of resistant pathogens. Thus, this study aimed to assess the appropriateness of antibiotics use and associated factors among hospitalized patients.

Methods:

A hospital-based prospective follow-up study was conducted in internal medicine. Data were collected by chart review and interview of prescribers and patients using a pre-tested questionnaire derived from RAND modified Delphi method. Appropriate antibiotic use means that the patient receives the drug based on culture result at the right time in adequate doses and duration. Frequencies and percentage distribution of dependent variables were analyzed. Moreover, bivariate and multivariate analyses were used to assess the factors influencing factors.

Result:

Of the 303 study participants, the mean age was44.36 ± 1.07 years and the majority 173 (57.1%) of the participants were females. The appropriateness of antibiotics use among hospitalized patients was 26 (8.6%). Males have used antibiotics more appropriately than females [5.99 (Adjusted odd ration (AOR) 95% CI 2.00-7.98)], while employed study participants were used antibiotics more appropriately than nonemployees [7.29 (AOR 95% CI 1.34-9.58)]. Moreover, patients who received antibiotics after blood culture [2.74 (AOR 95% CI 1.09-8.37)] and cerebrospinal fluid culture [5.82 (AOR 95% CI 1.84-5.63)] were used antibiotics more appropriately than patients who received antibiotics without culture. In addition, patients who believe that the prescribed antibiotics prevent complication of the disease [4.21 (AOR 95% CI 1.33-7.35)] were used antibiotics more appropriately than those who didn’t understand the use of antibiotics.

Conclusion:

The appropriateness of antibiotics use was very low in the study area. Patient gender, ethnicity, source of income, patient’s belief in antibiotics, and specimen cultures were significantly associated with the appropriateness of antibiotics use.

Identifying Recommendations for Stopping or Scaling Back Unnecessary Routine Services in Primary Care

IMPORTANCE

Much of health care involves established, routine use of medical services for chronic conditions or prevention. Stopping these services when the evidence changes or if the benefits no longer outweigh the risks is essential. Yet, most guidelines focus on escalating care and provide few explicit recommendations to stop or scale back (ie, deintensify) treatment and testing.

OBJECTIVE

To develop a systematic, transparent, and reproducible approach for identifying, specifying, and validating deintensification recommendations associated with routine adult primary care.

DESIGN, SETTING, AND PARTICIPANTS

A focused review of existing guidelines and recommendations was completed to identify and prioritize potential deintensification indications. Then, 2 modified virtual Delphi expert panels examined the synthesized evidence, suggested ways that the candidate recommendations could be improved, and assessed the validity of the recommendations using the RAND/UCLA Appropriateness Method. Twenty-five physicians from Veterans Affairs and US academic institutions with knowledge in relevant clinical areas (eg, geriatrics, primary care, women's health, cardiology, and endocrinology) served as panel members.

MAIN OUTCOMES AND MEASURES

Validity of the recommendations, defined as high-quality evidence that deintensification is likely to improve patient outcomes, evidence that intense testing and/or treatment could cause harm in some patients, absence of evidence on the benefit of continued or repeated intense treatment or testing, and evidence that deintensification is consistent with high-quality care.

RESULTS

A total of 409 individual recommendations were identified representing 178 unique opportunities to stop or scale back routine services (eg, stopping population-based screening for vitamin D deficiency and decreasing concurrent use of opioids and benzodiazepines). Thirty-seven recommendations were prioritized and forwarded to the expert panels. Panelists reviewed the evidence and suggested modifications, resulting in 44 recommendations being rated. Overall, 37 recommendations (84%) were considered to be valid, as assessed by the RAND/UCLA Appropriateness Method.

CONCLUSIONS AND RELEVANCE

In this study, a total of 178 unique opportunities to deintensify routine primary care services were identified, and 37 of these were validated as high-priority deintensification recommendations. To date, this is the first study to develop a model for identifying, specifying, and validating deintensification recommendations that can be implemented and tracked in clinical practice.

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.

Nosocomial Infections: A History of Hospital-Acquired Infections

In the United States, healthcare acquired infections (HAIs) or nosocomial infections are the sixth leading cause of death. This article reviews the history, prevalence, economic costs, morbidity and mortality, and risk factors associated with HAIs. Types of infections described include bacterial, fungal, viral, and multidrug resistant infections that contribute to the most common causes of HAIs, which include catheter- associated urinary tract infections, hospital-acquired pneumonias, bloodstream infections, and surgical site infections. Most nosocomial infections are preventable and monitoring and prevention strategies are described.

Impact of a hospital-wide huddle on device utilisation and infection rates: a community hospital's journey to zero

Background

Device utilisation ratios (DUR) correlate with device-associated complications and rates of infection. We implemented a hospital-wide Daily Interdisciplinary Safety Huddle (DISH) with infection control and device components. The aim of this study was to evaluate the impact of DISH on DURs and rates of infection for indwelling urinary catheters (IUC) and central venous catheters (CVC).

Methods

A quasi-experimental study assessing DURs and rates of infection before and after implementation of DISH. At DISH, usage of IUC and CVC is reported by managers and the infection preventionist reviews indications and plans for removal. Data before and after implementation were compared. Paired T-test was used to assess for differences between both groups.

Results

DISH was successfully implemented at a community hospital. The average DUR for IUC in intensive care unit (ICU) and non-ICU settings was reduced from 0.56 to 0.35 and 0.27 to 0.12, respectively. CVC DUR decreased from 0.29 to 0.26 in the ICU and 0.14 to 0.12 in non-ICU settings. Catheter-associated urinary tract infections (CAUTIs) decreased by 87% and central line-associated bloodstream infections (CLABSIs) by 96%.

Conclusion

DISH was associated with hospital-wide reductions in DUR and device-associated healthcare-associated infections. Reduction of CLABSIs and CAUTIs had estimated cost savings of $688,050. The impact was more profound in non-ICU settings. To our knowledge, an infection prevention hospital-wide safety huddle has not been reported in the literature. DISH increased device removal, accountability and promoted a culture of safety.

A prevalence survey of patients with indwelling urinary catheters on district nursing caseloads in the United Kingdom: The Community Urinary Catheter Management (CCaMa) Study

Background

Catheter-associated urinary tract infection (CAUTI) is common in both hospitals and the community.

Aim

To investigate the prevalence of indwelling urinary catheters on district nursing caseloads in the UK.

Methods

Participants were recruited through the Infection Prevention Society (IPS). An electronic survey was undertaken on a single day between November 2017 and January 2018. Data were analysed using descriptive statistics.

Findings

A total of 49,575 patients were included in the survey, of whom 5352 had an indwelling urinary catheter. This gave a point prevalence of 10.8% (95% confidence interval [CI] = 10.53-11.07), which varied between organisations, ranging from 2.36% (95% CI = 2.05-2.73) to 22.02% (95% CI = 20.12-24.05). Of catheters, 5% were newly placed (within four weeks). Of these, most (77%) had a documented indication for insertion. Only half of patients with a newly placed catheter had a plan for its removal. This varied between organisations in the range of 20%-96%. Only 13% of patients had a patient-held management plan or 'catheter passport' but these patients were significantly more likely to also have an active removal plan (28/36 [78%] vs. 106/231 [46%]; P < 0.0001). Alternative bladder management strategies had been considered for 70/267 (26%) patients.

Discussion

The management of patients with an indwelling urinary catheter represents a significant component of district nursing caseloads. Given the high proportion of newly catheterised patients without an active management plan for removal of the catheter, the establishment of an optimal management pathway should be the focus of future prevention efforts.

Impact of an evidence-based intervention on urinary catheter utilization, associated process indicators, and infectious and non-infectious outcomes

BACKGROUND

Multi-centre intervention studies tackling urinary catheterization and its infectious and non-infectious complications are lacking.

AIM

To decrease urinary catheterization and, consequently, catheter-associated urinary tract infections (CAUTIs) and non-infectious complications.

METHODS

Before/after non-randomized multi-centre intervention study in seven hospitals in Switzerland. Intervention bundle consisting of: (1) a concise list of indications for urinary catheterization; (2) daily evaluation of the need for ongoing catheterization; and (3) education on proper insertion and maintenance of urinary catheters. The primary outcome was urinary catheter utilization. Secondary outcomes were CAUTIs, non-infectious complications and process indicators (proportion of indicated catheters and frequency of catheter evaluation).

FINDINGS

In total, 25,880 patients were included in this study [13,171 at baseline (August-October 2016) and 12,709 post intervention (August-October 2017)]. Catheter utilization decreased from 23.7% to 21.0% (P=0.001), and catheter-days per 100 patient-days decreased from 17.4 to 13.5 (P=0.167). CAUTIs remained stable at a low level with 0.02 infections per 100 patient-days (baseline) and 0.02 infections (post intervention) (P=0.98). Measuring infections per 1000 catheter-days, the rate was 1.02 (baseline) and 1.33 (post intervention) (P=0.60). Non-infectious complications decreased significantly, from 0.79 to 0.56 events per 100 patient-days (P<0.001), and from 39.4 to 35.4 events per 1000 catheter-days (P=0.23). Indicated catheters increased from 74.5% to 90.0% (P<0.001). Re-evaluations increased from 168 to 624 per 1000 catheter-days (P<0.001).

CONCLUSION

A straightforward bundle of three evidence-based measures reduced catheter utilization and non-infectious complications, whereas the proportion of indicated urinary catheters and daily evaluations increased. The CAUTI rate remained unchanged, albeit at a very low level.

Relationship between the Severity of Coronary Artery Disease and Catheter-Associated Urethral Stricture in Patients with Acute Coronary Syndrome

Background: Different arterial segments throughout the vascular system develop similar grades of atherosclerosis concomitantly. Urethral ischemia has been proposed as a cause of urethral stricture. Therefore, we aimed to investigate the relationship between coronary artery disease severity using a SYNTAX score and urethral stricture occurrence after urethral catheterization in patients with non-ST-segment-elevation acute coronary syndrome (ACS). Methods: This retrospective study consisted of 306 men with urethral catheters that were diagnosed with ACS and underwent coronary angiography between January 2016 and January 2018 in Kars Kafkas University and Osmaniye Government Hospital, Turkey. Hospital records were reviewed to collect the follow-up data of the patients regarding the occurrence of urethral stricture after urethral catheterization. The study population was divided into 2 groups according to urethral stricture development, and both groups were compared statistically. Results: SYNTAX scores were significantly higher in patients with urethral stricture than in those without urethral stricture (14.86±7.11 vs. 29.25±9.79; P<0.001). The SYNTAX score (OR=1.27; 95% CI: 1.16-1.39; P<0.001), diabetes, and serum albumin were found to be the independent predictors of urethral stricture. The receiver operating characteristic curve analysis showed that the cutoff value of the SYNTAX score for urethral stricture prediction was greater than 22.5, with 76.7% sensitivity and 85.1% specificity (AUC=0.88, 95% CI: 0.84-0.91; P<0.001). Conclusion: Coronary artery disease severity graded according to the SYNTAX score is an independent predictor of urethral stricture occurrence in ACS patients with a urethral catheter inserted.

Reducing unnecessary urethral catheter use in Japanese intensive care units: A multicenter interventional study

We conducted a preintervention-postintervention study to assess the effectiveness of a multimodal approach to reduce unnecessary urethral catheters in 5 Japanese intensive care units. After the intervention urethral catheter point prevalence decreased by 18%, from 79% preintervention to 61% postintervention, and catheter appropriateness increased by 28%, from 57% preintervention to 85% postintervention.

Developing Appropriateness Criteria for Pediatric Vascular Access

OBJECTIVES

To describe the methodology undertaken to provide guidance on the appropriateness, as well as inappropriateness, of vascular access device selection, characteristics, and insertion technique for pediatric patients.

METHODS

The RAND Corporation-University of California, Los Angeles Appropriateness Method was used. After definition of key terms and scope, a systematic review of the pediatric vascular access literature was undertaken. Clinical scenarios were developed to reflect the common indications for vascular access across pediatric health care. These were sectioned according to (1) device selection, (2) device characteristics, and (3) insertion technique. An interdisciplinary panel of experts (N = 14) consisting of leading experts representing diverse pediatric clinical disciplines including anesthesiology, cardiology and cardiac surgery, critical care and emergency, general surgery, hematology and oncology, hospital medicine, infectious disease, interventional radiology, pharmacology, regional pediatric hospitalist, and vascular access nursing specialties was convened. The scenarios were rated for appropriateness by the panel over 2 rounds (1 [highly inappropriate] to 9 [highly appropriate]). Round 1 ratings were completed anonymously and independently by panel members and classified into 3 levels of appropriateness: appropriate, uncertain, and inappropriate, or disagreement. For round 2, panelists met in-person to discuss the round 1 ratings and independently rerated the indications. All indications were reclassified into 3 levels of appropriateness or disagreement.

CONCLUSIONS

The RAND Corporation-University of California, Los Angeles Appropriateness Method provides a rigorous, in-depth and transparent methodology to develop the first appropriateness criteria for the selection of pediatric vascular access devices in a range of patient groups.

Prevalence and risk factors of inappropriate use of intravenous and urinary catheters in surgical and medical patients

BACKGROUND

Previously, the RICAT (Reduction of Inappropriate use of intravenous and urinary CATheters) study had been conducted by ourselves to reduce inappropriate use of intravenous and urinary catheters in medical wards to prevent healthcare-associated infections.

AIM

To compare surgical and medical wards, and to determine risk factors for inappropriate catheter use.

METHODS

A cross-sectional study was performed from October, 2017, to May, 2018, in surgical wards of two university hospitals in the Netherlands. Patients were prospectively observed every other week for seven months. Inappropriate use was compared with non-surgical wards in the RICAT study.

FINDINGS

In all, 409 surgical patients were included, and they were compared with 1781 medical patients. Inappropriate use occurred in 36 (8.5%) out of 425 peripheral intravenous catheters in 373 surgical patients, compared to 400 (22.9%) out of 1747 peripheral intravenous catheters in 1665 medical patients, a difference of 14.4% (95% confidence interval (CI): 11.1-17.8; P < 0.001). Inappropriate use of urinary catheters occurred in 14 (10.4%) out of 134 surgical patients, compared to 105 (32.4%) out of 324 medical patients, a difference of 22.0% (95% CI: 14.7-29.2; P < 0.001). Subgroup analysis in the two university hospitals confirmed these differences. The main risk factor for inappropriate use of peripheral intravenous catheters was admission in medical wards (odds ratio (OR): 3.50; 95% CI: 2.15-5.69), which was also one of the main risk factors for urinary catheters (OR: 2.75; 95% CI: 1.36-5.55).

CONCLUSION

Inappropriate use of catheters is more common in medical wards compared to surgical wards. Prevention strategies to reduce healthcare-associated infections should primarily focus on sites with high prevalence of inappropriate use.

Inappropriate initial urinary catheter placement among older Chinese hospital inpatients: An observational study

AIM

The aim of this study is to evaluate incidences of inappropriate initial urinary catheter placements within an older inpatient cohort.

METHODS

A total of 200 inpatients that received urinary catheterizations within 24 hours of admission were recruited for this observational study. The key demographic and clinical factors were recorded. Adverse outcomes were assessed by examining incidences of catheter-associated urinary tract infection (CAUTI) during hospitalization, after transfer to skilled nursing facilities, second, duration of hospital stay and by scoring changes on the Katz Index of Independence in Activities of Daily Living. Correlative relationships between demographic data and clinical factors with adverse outcomes were analyzed.

RESULTS

Inappropriate initial urinary catheterization in our cohort was approximately 39%. This was associated with elevated Charlson comorbidity index scores and increased dependency, with correlations to medical diagnosis. We also observed that the primary rationale for the procedure (inappropriate catheterization) was for neurogenic bladder (where intermittent catheterization was indicated) and in 'convenience-of-care' catheterizations. Inappropriate catheter placement was ultimately associated with an elevated CAUTI at point of discharge, with transfers to skilled nursing facilities and also with an increased duration of hospital stay.

CONCLUSIONS

Inappropriate catheter placement was prevalence in southwestern China and associated with adverse outcomes.

Prevalence, impact, and management strategies for asymptomatic bacteriuria in the acute care elderly patient: a review of the current literature

Introduction: It is unclear how to prevent the negative impact of inappropriate urine cultures in older acute care patients who have a high rate of asymptomatic bacteriuria.Areas covered: A nonsystematic literature review of the definition, impact, and management of elderly acute care patients with asymptomatic bacteriuria (ASB).Expert opinion: In the elderly, patients with ASB include those with extra-urinary tract diseases (e.g. pneumonia) and those with symptoms/signs that resolve without antibiotic therapy, but the diagnosis of ASB is unclear in febrile patients responding to antibiotics. We consider four management strategies that could decrease the negative impact of culturing the urine including unnecessary antibiotic therapy in those with ASB: (1) Prevent urine testing in patients with extra-urinary tract reasons for their acute care (2) Cancel urine cultures if the urine dipstick is negative. (3) Avoid catheterization in stable patients who cannot provide a urine specimen on demand and (4) Withhold antibiotics in stable non-febrile elderly patients who do not have new local urinary tract symptoms or decompensation on follow-up, and pursue further investigations for another etiology/diagnosis.

The development of a modified comprehensive geriatric assessment for use in the emergency department using a RAND/UCLA appropriateness method

BACKGROUND

The universal screening and comprehensive assessment of older persons presenting to the emergency department is considered useful, yet is difficult to embed. A number of assessment instruments exist however they are not widely used and there is a lack of agreement between clinicians as to which tools are best suited to the emergency department. The aim of this study was to develop a modified comprehensive geriatric assessment using consensus methodology for use by the multidisciplinary team in the emergency department.

METHOD

The modified comprehensive geriatric assessment was formulated using the RAND/UCLA appropriateness methodology incorporating consensus opinion from an expert group of clinicians and the best scientific evidence available. A series of pre and post survey and expert group meetings were held with expert multidisciplinary clinicians. Emphasis was placed on a pragmatic approach to the development of a document which reflected consensus opinion.

RESULTS

Between nine and 15 expert group members participated in the stages of the process. A tiered approach incorporating different aspects of screening and/or assessments was considered optimal to reflect the stages of decision-making in the emergency department process.

CONCLUSION

A unique approach to the screening and assessment of the frail older person was developed using consensus methodology to develop a modified comprehensive geriatric assessment for use in the emergency department. Associated actions and interventions are an important next step, with pilot site testing.

De-implementation strategy to reduce inappropriate use of intravenous and urinary catheters (RICAT): a multicentre, prospective, interrupted time-series and before and after study

BACKGROUND

Catheter-associated bloodstream infections and urinary tract infections are frequently encountered health care-associated infections. We aimed to reduce inappropriate use of catheters to reduce health care-associated infections.

METHODS

In this multicentre, interrupted time-series and before and after study, we introduced a de-implementation strategy with multifaceted interventions in seven hospitals in the Netherlands. Adult patients admitted to internal medicine, gastroenterology, geriatic, oncology, or pulmonology wards, and non-surgical acute admission units, and who had a (central or peripheral) venous or urinary catheter were eligible for inclusion. One of the interventions was that nurses in the participating wards attended educational meetings on appropriate catheter use. Data on catheter use were collected every 2 weeks by the primary research physician during the baseline period (7 months) and intervention period (7 months), which were separated by a 5 month transition period. The primary outcomes were percentages of short peripheral intravenous catheters and urinary catheters used inappropriately on the days of data collection. Indications for catheter use were based on international guidelines. This study is registered with Netherlands Trial Register, NL5438.

FINDINGS

Between Sept 1, 2016, and April 1, 2018, we screened 6157 patients for inclusion, of whom 5696 were enrolled: 2650 patients in the baseline group, and 3046 in the intervention group. Inappropriate use of peripheral intravenous catheters occurred in 366 (22·0%, 95% CI 20·0 to 24·0) of 1665 patients in the baseline group and in 275 (14·4%, 12·8 to 16·0) of 1912 patients in the intervention group (incidence rate ratio [IRR] 0·65, 95% CI 0·56 to 0·77, p<0·0001). Time-series analyses showed an absolute reduction in inappropriate use of peripheral intravenous catheters from baseline to intervention periods of 6·65% (95% CI 2·47 to 10·82, p=0·011). Inappropriate use of urinary catheters occurred in 105 (32·4%, 95% CI 27·3 to 37·8) of 324 patients in the baseline group compared with 96 (24·1%, 20·0 to 28·6) of 398 patients in the intervention group (IRR 0·74, 95% CI 0·56 to 0·98, p=0·013). Time-series analyses showed an absolute reduction in inappropriate use of urinary catheters of 6·34% (95% CI -12·46 to 25·13, p=0·524).

INTERPRETATION

Our de-implementation strategy reduced inappropriate use of short peripheral intravenous catheters in patients who were not in the intensive care unit. The reduction of inappropriate use of urinary catheters was substantial, yet not statistically significant in time-series analysis due to a small sample size. The strategy appears well suited for broad-scale implementation to reduce health care-associated infections.

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.

Multistate programme to reduce catheter-associated infections in intensive care units with elevated infection rates

Background

Preventing central line-associated bloodstream infection (CLABSI) and catheter-associated urinary tract infection (CAUTI) remains challenging in intensive care units (ICUs).

Objective

The Agency for Healthcare Research and Quality Safety Program for ICUs aimed to reduce CLABSI and CAUTI in units with elevated rates.

Methods

Invited hospitals had at least one adult ICU with elevated CLABSI or CAUTI rates, defined by a positive cumulative attributable difference metric (CAD >0) in the Centers for Disease Control and Prevention’s Targeted Assessment for Prevention strategy. This externally facilitated programme implemented by a national project team and state hospital associations included on-demand video modules and live webinars reviewing a two-tiered approach for implementing key technical and socioadaptive factors to prevent catheter infections, using principles and tools based on the Comprehensive Unit-based Safety Program. CLABSI, CAUTI and catheter use data were collected (preintervention 13 months, intervention 12 months). Multilevel negative binomial models assessed changes in catheter-associated infection rates and catheter use.

Results

Of 366 recruited ICUs from 220 hospitals in 16 states and Puerto Rico for two cohorts, 280 ICUs completed the programme including infection outcome reporting; 274 ICUs had complete outcome data for analyses. Statistically significant reductions in adjusted infection rates were not observed (CLABSI incidence rate ratio (IRR)=0.75, 95% CI 0.52 to 1.08, p=0.13; CAUTI IRR=0.79, 95% CI 0.59 to 1.06, p=0.12). Adjusted central line utilisation (IRR=0.97, 95% CI 0.93 to 1.00, p=0.09) and adjusted urinary catheter utilisation were unchanged (IRR=0.98, 95% CI 0.95 to 1.01, p=0.14).

Conclusion

This multistate programme targeted ICUs with elevated catheter infection rates, but yielded no statistically significant reduction in CLABSI, CAUTI or catheter utilisation in the first two of six planned cohorts. Improvements in the interventions based on lessons learnt from these initial cohorts are being applied to subsequent cohorts.

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.

Persistent Barriers to Timely Catheter Removal Identified from Clinical Observations and Interviews

BACKGROUND

Indwelling urinary and vascular catheters are valuable devices in patient care, but prolonged or unnecessary use increases the risk of infectious and noninfectious catheter harms.

METHODS

To understand persistent barriers to detecting and removing unnecessary catheters, researchers conducted a multimethod qualitative study that included observations and in-person interviews with clinicians working on a progressive care unit of a large hospital. Observations consisted of shadowing nurses during shift change and while admitting patients, and observing physicians during morning rounds. Observational data were gathered using unstructured field notes. Interviews were conducted using a semistructured guide, audio-recorded, and transcribed. Qualitative content analysis was conducted to identify main themes.

RESULTS

Barriers to timely removal identified during 19 interviews with clinicians and 133 hours of field observations included physicians not routinely reviewing catheter necessity during rounds, catheters going unnoticed or hidden under clothing, common use of "Do Not Remove" orders, and little or no discussion of catheters among clinicians. Five overall themes emerged: (1) Catheter data are hard to find, not accurate, or not available; (2) Catheter removal is not a priority; (3) Confusion exists about who has authority to remove catheters; (4) There is a lack of agreement on, and awareness of, standard protocols and indications for removal; and (5) Communication barriers among clinicians create challenges.

CONCLUSION

To address barriers and facilitate detection and timely removal, clinicians need ready access to accurate catheter data, more clearly delineated clinician roles for prompting removal, effective tools to facilitate discussions about catheter use, and standardized catheter removal protocols.
