Nursing Home Clinicians' Decision to Prescribe Antibiotics for a Suspected Urinary Tract Infection: Findings From a Discrete Choice Experiment

Patient Factors Influencing Prescription of Antithrombotic Medication After Lower Limb Endovascular Intervention

OBJECTIVE

There is significant practice variation in the use of antithrombotic therapy after endovascular intervention for lower limb peripheral arterial disease, with differences in medication choice and duration. Prescriber decision making is complex, and patient factors have been shown to substantially contribute to prescribing variation. To determine the influence of patient factors on antithrombotic prescribing, a discrete choice experiment was distributed to vascular surgeons and trainees across Australia and Aotearoa New Zealand.

METHODS

After pilot testing, the discrete choice experiment questionnaire was distributed to 300 vascular surgeons and trainee members of the Australian and New Zealand Society for Vascular Surgery. Multinomial logistic regression models were used to analyse patient factors that had the most influence on decisions to prescribe a second antithrombotic agent, and the preferred choice of antithrombotic (clopidogrel 75 mg daily or rivaroxaban 2.5 mg twice daily) in addition to aspirin 100 mg daily. The odds ratio (OR) with 95% confidence interval (CI) reported preference strength.

RESULTS

A total of 44 questionnaires were completed between September and October 2023, reaching the 15% targeted response rate. Prescribing a second antithrombotic was more likely after femoropopliteal stenting compared with angioplasty (OR 1.89, 95% CI 1.20 - 2.13), and in chronic limb threatening ischaemia compared with intermittent claudication (OR 1.58, 95% CI 1.20 - 2.13). Most respondents preferred clopidogrel over rivaroxaban (62%), with over a third of respondents exclusively prescribing clopidogrel. Patients with stents (OR 1.77, 95% CI 1.32 - 2.37) or moderate bleeding risk (OR 1.38, 95% CI 0.97 - 1.84) were more likely to receive clopidogrel than rivaroxaban.

CONCLUSION

This study demonstrates that vascular surgeons primarily prioritise antithrombotic prescribing decisions by procedure type. Clopidogrel is more likely to be prescribed than rivaroxaban as a second agent in combination with aspirin, especially after stenting. Knowing these clinician preferences can target implementation strategies towards supporting decision making in subgroups of patients according to individual risk profiles.

Detection and management of suspected infections in people with dementia - A scoping review of current practices

People with dementia have an increased risk of hospitalization and mortality due to infections. We aimed to explore decision-making processes and interventions for detecting and managing suspected infections in people with dementia and involved actors and determinants. We conducted a scoping review, searching CINAHL and PubMed, and synthesized data through mapping and narratively. We identified 22 studies, based mostly on nursing homes and US data. Decision-making processes included recognition of infections based on observations of early signs and symptoms, actions when suspecting infections, and proxy/family involvement. Interventions included antimicrobial stewardship and other decision-support tools. Determinants included healthcare staff perceptions, and other system/person-related factors. Healthcare staff were the main actors, proxy/family were mentioned scarcely, and people with dementia only once. Our findings show scarcity of evidence on people with dementia and outside of the nursing homes. We highlight knowledge gaps and inform research shaping interventions for improving infection detection and management.

Health care professionals' knowledge and attitudes towards antibiotic prescribing for the treatment of urinary tract infections: A systematic review

PURPOSE

Previous models identify knowledge and attitudes that influence prescribing behaviour. The present study focuses on antibiotic prescribing for urinary tract infections (UTIs) to describe levels of health care professionals' knowledge and attitude factors in this area and how those levels are assessed.

METHODS

A systematic search was conducted to identify studies assessing the identified knowledge or attitude factors influencing health care professionals' antibiotic prescribing for urinary tract infections up to September 2022. Study quality was assessed using the Newcastle-Ottawa scale. Data were extracted about the types of factors assessed, the levels indicated and how those levels were assessed. Data were synthesized using counts, and levels were categorized as 'poor', 'moderate', 'high' or 'very high'.

RESULTS

Seven studies were identified, six of which relied entirely on closed-ended items. Levels of knowledge factors assessed were poor, for example, their 'knowledge of condition' and 'knowledge of task environment' were poor. Levels of the attitude factors assessed varied, for example, while health care professionals expressed moderate confidence in providing optimal patient care and appropriate attitude of fear towards the problem of antibiotic resistance, they expressed a poor attitude of complacency by giving into patient pressure to prescribe an antibiotic.

CONCLUSIONS

Present evidence suggests that clinicians have poor levels of knowledge and varying levels of attitudes about antibiotic prescribing for UTIs. However, few studies were identified, and assessments were largely limited to closed-ended types of questions. Future studies that assess more factors and employ open-ended question types could better inform future interventions to optimize antibiotic prescribing.

Prescriber decision-making on antithrombotic therapy after endovascular intervention for peripheral artery disease: a protocol for a discrete choice experiment

INTRODUCTION

Peripheral artery disease (PAD) is a major risk factor for cardiovascular morbidity and mortality, despite surgical and endovascular treatments. Emerging evidence supports the use of immediate antithrombotic medications after endovascular intervention for PAD, however, there is a lack of consensus regarding choice and duration of antithrombotic therapy. Prescriber decision-making is a complex process, with prior studies demonstrating patient factors can influence variability in antithrombotic therapy for PAD. However, it remains unclear the relative contribution of these factors. This paper describes a planned study that aims to (1) determine the influence of patient factors on clinician preference for antithrombotic therapy following endovascular intervention and (2) compare differences in prescribing preferences between consultant vascular surgeons and trainees.

METHODS AND ANALYSIS

This cross-sectional survey will evaluate antithrombotic prescribing choices using a discrete choice experiment (DCE) that has been developed and piloted for this study. A list of attributes and levels was generated using a mixed-methods approach. This included an extensive literature review and semistructured interviews with prescribing clinicians. Following final selection of included attributes, specialised software was used to construct a D-efficient design for the DCE questionnaire. The electronic questionnaire will be administered to vascular trainees and consultant surgeons across Australia. These data will be analysed using multinomial logistic regression, treating the decision to prescribe antithrombotic therapy as a function of both the attributes of the two alternatives, as well as characteristics of the respondent. Latent class analysis will be used to explore heterogeneity of responses.

ETHICS AND DISSEMINATION

Ethics approval was obtained from the University of Sydney Human Ethics committee (2023/474). The results of this study will be published in peer-reviewed journals and presented at national vascular surgical conferences. These results will be used to improve understanding how clinicians make prescribing decisions and to inform future strategy to enhance guideline-directed prescribing.

Resident-, prescriber-, and facility-level factors associated with antibiotic use in long-term care facilities: a systematic review of quantitative studies

BACKGROUND

Antimicrobial stewardship programmes are needed in long-term care facilities (LTCFs) to tackle antimicrobial resistance. We aimed to identify factors associated with antibiotic use in LTCFs. Such information would be useful to guide antimicrobial stewardship programmes.

METHOD

We conducted a systematic review of studies retrieved from PubMed, Cochrane Library, Embase, APA PsycArticles, APA PsycINFO, APA PsycTherapy, ScienceDirect and Web of Science. We included quantitative studies that investigated factors associated with antibiotic use (i.e., antibiotic prescribing by health professionals, administration by LTCF staff, or use by residents). Participants were LTCF residents, their family, and/or carers. We performed a qualitative narrative synthesis of the findings.

RESULTS

Of the 7,591 screened records, we included 57 articles. Most studies used a longitudinal design (n = 34/57), investigated resident-level (n = 29/57) and/or facility-level factors (n = 32/57), and fewer prescriber-level ones (n = 8/57). Studies included two types of outcome: overall volume of antibiotic prescriptions (n = 45/57), inappropriate antibiotic prescription (n = 10/57); two included both types. Resident-level factors associated with a higher volume of antibiotic prescriptions included comorbidities (5 out of 8 studies which investigated this factor found a statistically significant association), history of infection (n = 5/6), potential signs of infection (e.g., fever, n = 4/6), positive urine culture/dipstick results (n = 3/4), indwelling urinary catheter (n = 12/14), and resident/family request for antibiotics (n = 1/1). At the facility-level, the volume of antibiotic prescriptions was positively associated with staff turnover (n = 1/1) and prevalence of after-hours medical practitioner visits (n = 1/1), and negatively associated with LTCF hiring an on-site coordinating physician (n = 1/1). At the prescriber-level, higher antibiotic prescribing was associated with high prescription rate for antibiotics in the previous year (n = 1/1).

CONCLUSIONS

Improving infection prevention and control, and diagnostic practices as part of antimicrobial stewardship programmes remain critical steps to reduce antibiotic prescribing in LTCFs. Once results confirmed by further studies, implementing institutional changes to limit staff turnover, ensure the presence of a professional accountable for the antimicrobial stewardship activities, and improve collaboration between LTCFs and external prescribers may contribute to reduce antibiotic prescribing.

Implementation of an intervention to reduce urine dipstick testing in aged care homes: a qualitative study of enablers and barriers, and strategies to enhance delivery

OBJECTIVE

The 'To Dip or Not to Dip' (TDONTD) intervention aims to reduce antibiotic prescribing for urinary tract infection (UTI) by reducing low-value dipstick testing. The aims of this study were to use a qualitative approach to (1) evaluate potential influences on the delivery of the TDONTD intervention in Australian residential aged care homes (RACHs) by identifying perceived barriers and enablers to delivery and acceptance; and (2) propose intervention strategies to address barriers and enhance enablers.

DESIGN

A qualitative before-after process evaluation of a multisite implementation study using interviews with nurse and pharmacist implementers.

SETTING

This study was conducted in 12 Australian RACHs.

PARTICIPANTS

Participants included 17 on-site nurse champions and 4 pharmacists (existing contracted providers).

INTERVENTION

Resources from England's TDONTD intervention were adapted for an Australian context. Key resources delivered were case-based education, staff training video, clinical pathway and an audit tool.

RESULTS

Key barriers to TDONTD were beliefs about nursing capabilities in diagnosing infection, beliefs about consequences (fear of missing infection) and social influences (pressure from family, doctors and hospitals). Key enablers were perceived increased nurse and carer knowledge (around UTI and asymptomatic bacteriuria), resources from a credible source, empowerment of nurse champions to apply knowledge and skills in delivering operational change initiatives, pharmacist-delivered education and organisational policy or process change. Of TDONTD's key components, the clinical pathway substituted dipstick testing in diagnosing UTI, delivery of case-based education was enhanced by their attendance and support of the intervention and the antibiotic audit tool generated feedback that champions shared with staff.

CONCLUSIONS

Our study confirms the core components of TDONTD and strategies to enhance delivery and overcome barriers. To further reduce barriers to TDONTD, broader advocacy work is required to raise awareness of dipstick testing as a low-value test in older persons and by linking it to healthcare professionals and consumer education.

Determining the Appropriateness of Initiating Antibiotic Therapy in Nursing Home Residents

One approach for improving antibiotic prescribing in nursing homes is evaluating appropriateness of initiating antibiotic therapy. However, determining appropriateness has been a challenge. To investigate this problem literature review identified studies evaluating appropriateness of initiating antibiotic therapy in nursing homes. Two criteria were used most often to assess appropriateness: infection surveillance criterion or criteria specifically designed to assist clinicians for prescribing antibiotics. Development of these criteria and results of studies using these criteria were reviewed. There was considerable variability in percentage appropriateness of initiating therapy for these criteria, variation in the methodology for conducting these studies, and limitations of the criteria. The main limitation of infection surveillance criteria is that they are specifically designed to be highly specific but this results in low sensitivity. Thus, surveillance criteria should not be used for assessing appropriateness of antibiotic therapy. The other criterion is limited because it uses only localizing signs and symptoms of infection and these findings may not be documented in the medical record when evaluating appropriateness retrospectively. Several alternative methods to assess appropriateness were identified but evaluation of these methods have not been published. Several changes are suggested to improve the evaluation of the appropriateness of initiating antibiotic therapy in nursing home residents: confirmation by the Department of Health and Human Services and the Centers for Medicare & Medicaid Services that surveillance definitions should not be used to evaluate appropriateness; develop and validate definitions of clinical infections in residents; standardize methods to evaluate appropriateness prospectively by the facility antimicrobial stewardship program; educate clinicians and nursing staff regarding the criteria for assessing appropriateness; and investigate the influence of provider-, resident-, family-, and facility-level factors on antibiotic use in nursing home residents.

Patient-level information underlying overdiagnosis of urinary tract infections in nursing homes: A discrete choice experiment

The overdiagnosis of urinary tract infections (UTIs) in nursing home residents is a significant public health threat. Using a discrete choice experiment and a diagnostic guideline, we examined which patient-level information was associated with the overdiagnosis of UTIs and found that urinalysis results and lower urinary tract status were most associated.

How do aged-care staff feel about antimicrobial stewardship? A systematic review of staff attitudes in long-term residential aged-care

Background

Antimicrobial resistance (AMR) is a problem in residential aged care facilities (RACF). There is a gap in our understanding of how psychosocial barriers such as risk perceptions shape staff attitudes towards antimicrobial stewardship (AMS). We sought to ascertain the attitudinal domains that have been identified to be of importance to AMS in RACF and comment on how they have been measured empirically. Our aim was to consolidate what is known regarding staff attitudes and perceptions in order to inform future stewardship.

Method

We searched PsycINFO, PsycARTICLES, CINAHL Plus, MEDLINE, PubMed, Web of Science, Cochrane, and Scopus databases for primary studies of healthcare workers attitudes to AMS in RACF (1990-February 2021).

Results

14 Studies were included in the review, within which 10 domains were identified: attitudes towards antimicrobial prescribing; guidelines; educational interventions; self-confidence regarding clinical assessment and prescribing; awareness of AMR as a problem and stewardship as a priority; self-efficacy; perception of role; perception of risk; team culture and resident/family members expectations. 46 measures were developed across the 14 studies to measure the 10 domains. The variability in the attitudinal domains and how these domains were measured was large. Only 13% included psychometric data regarding reliability and/or internal consistency.

Conclusions

Attitudes are generally defined as having three evaluative bases: cognitive, behavioural, and affective. Findings from the current review suggest that the measures commonly used to capture healthcare staff attitudes to AMS do not sufficiently capture affect; particularly with respect to staff’s risk perceptions, perceptions of their role, and family members’ expectations. Given that affective processes have been postulated to influence medical decision making, these findings highlight the importance of understanding how staff, especially nurses feel about implementing AMS strategies and other peoples’ (e.g. residents and their families) perceptions of stewardship. It is expected that a more nuanced understanding of RACF nurses affective experiences when applying AMS, and their perceptions of the risks entailed, will help in reducing barriers to overprescribing antibiotics.

Antibiotic postprescribing modification opportunities among nursing home residents treated for urinary tract infection

Objective:

To characterize opportunities to postprescriptively modify antibiotic prescriptions initiated for treatment of suspected urinary tract infection (UTI) in nursing homes.

Design:

Cross-sectional cohort study.

Methods:

Data from the health records of residents treated for UTI between 2013 and 2014 in 5 Wisconsin nursing homes were abstracted using a structured approach. Explicit definitions were used to identify whether the prescribed antibiotic could have been stopped, shortened, or changed to a nonfluoroquinolone alternative. Antibiotic treatments appropriately modified by study nursing home providers in real time were not considered modifiable. Identification of >1 potential modification opportunity (eg, stop and shorten) per antibiotic treatment event was permitted.

Results:

In total, 356 eligible antibiotic treatment courses among 249 unique residents were identified. Only 59 antibiotic courses prescribed for treatment of suspected UTI (16.6%) were not amenable to any modification. Discontinuation of treatment due to lack of signs or symptoms of infection was the most frequently identified potential modification opportunity (66.2%). Although less common, substantial numbers of antibiotic treatment courses were potentially amenable to shortening (34%) or agent change (19%) modifications. If applied in concert at 72 hours after antibiotic initiation, stop and shorten modifications could eradicate up to 1,326 avoidable antibiotic days, and change modifications could remove a 32 remaining avoidable fluoroquinolone days.

Conclusions:

Substantial opportunity exists to enhance the quality of antibiotic prescribing for treatment of suspected UTI in nursing homes through postprescriptive review interventions. Additional studies examining how to best design and implement postprescriptive review interventions in nursing homes are needed.

Implementing an intervention to reduce use of antibiotics for suspected urinary tract infection in nursing homes - a qualitative study of barriers and enablers based on Normalization Process Theory

BACKGROUND

Overuse of antibiotics in the elderly population is contributing to the global health problem of antibiotic resistance. Hence, it is important to improve prescribing practices in care facilities for elderly residents. In nursing homes, urinary tract infection (UTI) is the most common reason for antibiotic prescription but inappropriate prescriptions are frequent. In order to reduce the use of antibiotics for suspected urinary tract infection in this context, a complex intervention based on education as well as tools for reflection and communication had been developed and trialed in a group of nursing homes. The presents study explored the barriers and enablers in implementing this complex intervention.

METHODS

After the intervention trial period, a qualitative interview study was performed in six of the nursing homes that had received the intervention. The study included 12 informants: One senior manager, four nurses, six healthcare assistants, and one healthcare helper. Normalization Process Theory was used to structure the interviews as well as the analysis.

RESULTS

The intervention was well received among the informants in terms of its purpose and content. The initial educational session had altered the informants' perceptions of UTI and of the need for adopting a different approach to suspected UTIs. Also, the study participants generally experienced that the intervention had positively impacted their practice. The most important barrier was that some of the interventions' clinical content was difficult to understand for the staff. This contributed to some problems with engaging all relevant staff in the intervention and with using the observation tool correctly in practice. Here, nurses played a key role in the implementation process by regularly explaining and discussing the intervention with other staff.

CONCLUSION

The results suggest that it is possible to implement more evidence-based practices concerning antibiotics use in nursing homes by employing a combination of educational activities and supportive tools directed at nursing home staff.

Resident-Related Factors Influencing Antibiotic Treatment Decisions for Urinary Tract Infections in Dutch Nursing Homes

The aim of this cohort study was to identify resident-related factors that influence antibiotic treatment decisions for urinary tract infections (UTIs) in nursing home residents and to provide an overview of the appropriateness of antibiotic treatment decisions according to the updated Dutch guideline for UTIs in frail older adults. The PROGRESS study dataset, consisting of 298 suspected UTI episodes in Dutch nursing home residents, was used. The presence of dysuria was associated with the highest frequency of antibiotic prescription (87.8%). Positive leukocyte esterase dipstick results showed the greatest increase in the risk of antibiotic prescription (RR 2.1, 95% CI 1.44 to 3.06). Treatment decisions were considered adequate in 64.1% of the suspected UTI episodes. Overtreatment occurred more often than undertreatment. Of the inadequate treatment decisions, 29.3% was due to treatment of UTI episodes in which solely non-specific symptoms were present. A high proportion of nitrofurantoin prescriptions were incorrect in UTIs with signs of tissue invasion (54.8%), indwelling catheter-associated UTIs (37.5%), and UTIs in men (29.2%). Although this is considered inadequate, non-specific symptoms were associated with antibiotic prescription for suspected UTIs in Dutch nursing home residents and nitrofurantoin was inadequately prescribed in particular groups, such as men.

Overdiagnosis of urinary tract infections by nursing home clinicians versus a clinical guideline

PURPOSE

To inform overprescribing and antibiotic stewardship in nursing homes (NHs), we examined the concordance between clinicians' (NH primary care providers and registered nurses) diagnosis of suspected UTI with a clinical guideline treated as the gold standard, and whether clinician characteristics were associated with diagnostic classification.

METHODS

We conducted a cross-sectional web-based survey of a U.S. national convenience sample of NH clinicians. The survey included a discrete choice experiment with 19 randomly selected clinical scenarios of NH residents with possible UTIs. For each scenario, participants were asked if they thought a UTI was likely. Responses were compared to the guideline to determine the sensitivity and specificity of clinician judgment and performance indicators. Multivariable logistic mixed effects regression analysis of demographic, work, personality, and UTI knowledge/attitudes characteristics was conducted.

RESULTS

One thousand seven hundred forty-eight NH clinicians responded to 33,212 discrete choice scenarios; 867 (50%) were NH primary care providers and 881 (50%) were NH registered nurses, 39% were male, and the mean age was 45 years. Participants were uncertain about diagnosis in 30% of scenarios. Correct classification occurred for 66% of all scenarios (providers: 70%; nurses: 62%). Respondent judgment had a sensitivity of 78% (providers: 81%; nurses: 74%) and specificity of 54% (providers: 59%; nurses: 49%) compared to the clinical guideline. Adjusting for covariates in multivariable models, being a nurse and having higher closemindedness were associated higher odds of false positive UTI (odds ratio [OR] 1.61, p < 0.001; and OR 1.09, p = 0.039, respectively), although higher UTI knowledge and conscientiousness were associated with lower odds of false positive UTI ratings (OR 0.80, p < 0.001; OR 0.90, p = 0.005, respectively).

CONCLUSIONS

Clinicians tend to over-diagnose urinary tract infections, necessitating systems-based interventions to augment clinical decision-making. Clinician type, UTI knowledge, and personality traits may also influence behavior and deserve further study.

A General Public Study on Preferences and Welfare Impacts of Antimicrobial Resistance in the United Kingdom

BACKGROUND

Antibiotics have led to considerable increases in life expectancy. However, over time, antimicrobial resistance has accelerated and is now a significant global public health concern. Understanding societal preferences for the use of antibiotics as well as eliciting the willingness to pay for future research is crucial.

OBJECTIVE

To investigate preferences for different strategies to optimize antibiotic use and to understand the willingness to pay for future research in antimicrobial resistance and antimicrobial drug development.

METHODS

A discrete-choice experiment was administered to a sample of the UK general population. Respondents were asked to make nine choices, each offering three options-two hypothetical "doctor and antibiotics" and one "no doctor-no antibiotics"-defined by five attributes: treatment, days needed to recover, risk of bacterial infection that needs antibiotics, risk of common side effects, and risk of antimicrobial resistance by 2050. Data were analyzed using random parameters logit models. A double-bounded contingent valuation was also included in the survey to explore the willingness to pay for policies to contain antimicrobial resistance.

RESULTS

Among the 2579 respondents who completed the survey, 1151 always selected "no doctor-no antibiotics" and 57 never varied their choices; therefore, 1371 responses were used in the analysis. Risk of antimicrobial resistance by 2050 was the most important attribute and the "treatment" was the least important attribute, although this was sensitive to a higher risk of bacterial infection. The aggregate annual willingness to pay for containing antimicrobial resistance was approximately £8.35 billion (~£5-£10 billion).

CONCLUSIONS

The antimicrobial resistance risk is relevant and important to the general public. The high willingness to pay suggests that large investments in policies or interventions to combat antimicrobial resistance are justified.

Effectiveness of a tailored intervention to reduce antibiotics for urinary tract infections in nursing home residents: a cluster, randomised controlled trial

BACKGROUND

When suspecting a urinary tract infection (UTI), the nursing home staff contacts a physician with clinical information on behalf of the resident; hence, poor understanding of UTI or a lack of clinical communicative skills can cause overtreatment with antibiotics. We investigated whether a tailored intervention that improves knowledge about UTI and communication skills in nursing home staff influences antibiotic prescriptions for UTI.

METHODS

This open-label, parallel-group, cluster randomised controlled trial was done at 22 participating nursing homes in Denmark. Patients were eligible if they were nursing home residents aged 65 years or older, had the nursing home listed as their permanent address, and resided in a living space designated for those with dementia or somatic health-care needs. We included nursing homes that were not participating in other UTI projects and those in which staff were present at all hours. Using computer-generated random numbers and stratification by municipality, a statistician randomised the nursing homes (1:1) to receive either interactive educational sessions and use of a dialogue tool or to continue standard practice. The statistical analysis was blinded. Staff attended 75 min sessions over 8 weeks to learn how to distinguish between UTIs and asymptomatic bacteriuria, evaluate non-specific symptoms, and use the dialogue tool. The primary outcome was the number of antibiotic prescriptions for acute UTI per resident per days at risk, defined as the number of days the resident had been present at the nursing home during the trial period. The trial is registered at ClinicalTrials.gov, NCT03715062.

FINDINGS

Between June 1, 2017, and June 1, 2018, 22 of 68 invited nursing homes were recruited. Of 22 randomised nursing homes (n=1625 residents), 11 received the intervention (770 [92·2%] of 835 allocated residents) and 11 were in the control group (705 [89·2%] of 790 allocated residents). The standardised number of nursing home staff was 572 in the intervention group and 535 in the control group. All nursing homes completed the trial. 65 residents were excluded from data collection in the intervention group and 85 were excluded in the control group. 1470 residents (intervention n=765; control n=705) were analysed for the primary endpoint. The number of antibiotic prescriptions for UTI per resident was 134 per 84 035 days at risk in the intervention group and 228 per 77817 days at risk in the control group. The rate ratio (RR) of receiving an antibiotic for UTI was 0·51 (95% CI 0·37-0·71) in the unadjusted model and 0·42 (0·31-0·57) in the adjusted model. Of 140 diary entries of suspected UTIs, no deaths were reported. 421 (28·5%) of 1475 residents were admitted to hospital. The risk of all-cause hospitalisation increased in the intervention group (adjusted model RR 1·28, 95% CI 0·95-1·74), whereas all-cause mortality was lower in the intervention group (0·91, 0·62-1·33).

INTERPRETATION

The intervention effectively reduced antibiotic prescriptions and inappropriate treatments for UTI without substantially influencing all-cause hospitalisations and mortality.

[Inadequate antibiotic prescribing and areas for improvement]

Inadequate antibiotic prescribing has been observed in many settings both in hospitals as well as in primary care. Most often there is uncertainty about the indication for antibiotic treatment itself, prescribers are reluctant to deescalate, and therapy duration is too long which results most often in overprescribing. The burden of overprescribing is difficult to estimate, but many studies in the hospital setting report a rate of approximately 30 % of inadequate prescribing - with wide variation. Over- but also underprescribing of antimicrobial agents is a serious patient safety issue that needs to be addressed in specific programmes at different levels of the healthcare system. Interventional studies have shown that programmes implementing or intensifying audit and feedback with clinical reevaluation by experts can be very efficient to reduce inadequate prescribing.

Nurse Decision-making for Suspected Urinary Tract Infections in Nursing Homes: Potential Targets to Reduce Antibiotic Overuse

OBJECTIVES

To determine what information is most important to registered nurses' (RNs) decisions to call clinicians about suspected urinary tract infections (UTIs) in nursing home residents.

DESIGN

Web-based discrete choice experiment with 19 clinical scenarios.

SETTING AND PARTICIPANTS

Online survey with a convenience sample of RNs (N = 881) recruited from a health care research panel.

METHODS

Clinical scenarios used information from 10 categories of resident characteristics: UTI risk, resident type, functional status, mental status, lower urinary tract status, body temperature, physical examination, urinalysis, antibiotic request, and goals of care. Participants were randomized into 2 deliberation conditions (self-paced, n = 437 and forced deliberation, n = 444). The degree to which evidence- and non-evidence-based information was important to decision-making was estimated using unconditional multinomial logistic regression.

RESULTS

For all nurses (22.8%) and the self-paced group (24.1%), lower urinary tract status had the highest importance scores for the decision to call a clinician about a suspected UTI. For the forced-deliberation group, body temperature was most important (23.7%), and lower urinary tract status was less important (21%, P = .001). The information associated with the highest odds of an RN calling about a suspected UTI was painful or difficult urination [odds ratio (OR) 4.85, 95% confidence interval (CI) 4.16-5.65], obvious blood in urine (OR 4.66, 95% CI 3.99-5.44), and temperature at 101.5° (OR 3.80, 95% CI 3.28-4.42). For the self-paced group, painful or difficult urination (OR 5.65, 95% CI 4.53-7.04) had the highest odds, whereas obvious blood in urine (OR 4.39, 95% CI 3.53-5.47) had highest odds for the forced-deliberation group.

CONCLUSIONS AND IMPLICATIONS

This study highlighted the importance of specific resident characteristics in nurse decision-making about suspected UTIs. Future antimicrobial stewardship efforts should aim to not only improve the previously studied overprescribing practices of clinicians, but to improve nurses' assessment of signs and symptoms of potential infections and how they weigh resident information.

Development of a Tailored, Complex Intervention for Clinical Reflection and Communication about Suspected Urinary Tract Infections in Nursing Home Residents

BACKGROUND

Inappropriate antibiotic treatments for urinary tract infections (UTIs) in nursing homes cause the development of resistant bacteria. Nonspecific symptoms and asymptomatic bacteriuria are drivers of overtreatment. Nursing home staff provide general practice with information about ailing residents; therefore, their knowledge and communication skills influence prescribing. This paper describes the development of a tailored, complex intervention for a cluster-randomised trial that targets the knowledge of UTI and communication skills in nursing home staff to reduce antibiotic prescriptions.

METHODS

A dialogue tool was drafted, drawing on participatory observations in nursing homes, interviews with stakeholders, and a survey in general practice. The tool was tailored through a five-phase process that included stakeholders. Finally, the tool and a case-based educational session were tested in a pilot study.

RESULTS

The main barriers were that complex patients were evaluated by healthcare staff with limited knowledge about disease and clinical reasoning; findings reported to general practice were insignificant and included vague descriptions; there was evidence of previous opinion bias; nonspecific symptoms were interpreted as UTI; intuitive reasoning led to the inappropriate suspicion of UTI.

CONCLUSION

Sustainable change in antibiotic-prescribing behaviour in nursing homes requires a change in nursing home staff's beliefs about and management of UTIs.

Reducing Antibiotic Prescriptions for Urinary Tract Infection in Nursing Homes Using a Complex Tailored Intervention Targeting Nursing Home Staff: Protocol for a Cluster Randomized Controlled Trial

BACKGROUND

Urinary tract infection (UTI) is the most common reason for antibiotic prescription in nursing homes. Overprescription causes antibiotic-related harms in those who are treated and others residing within the nursing home. The diagnostic process in nursing homes is complicated with both challenging issues related to the elderly population and the nursing home setting. A physician rarely visits a nursing home for suspected UTI. Consequently, the knowledge of UTI and communication skills of staff influence the diagnosis.

OBJECTIVE

The objective of this study is to describe a cluster randomized controlled trial with a tailored complex intervention for improving the knowledge of UTI and communication skills of nursing home staff in order to decrease the number of antibiotic prescriptions for UTI in nursing home residents, without changing hospitalization and mortality.

METHODS

The study describes an open-label cluster randomized controlled trial with two parallel groups and a 1:1 allocation ratio. Twenty-two eligible nursing homes are sampled from the Capital Region of Denmark, corresponding to 1274 nursing home residents. The intervention group receives a dialogue tool, and all nursing home staff attend a workshop on UTI. The main outcomes of the study are the antibiotic prescription rate for UTI, all-cause hospitalization, all-cause mortality, and suspected UTI during the trial period.

RESULTS

The trial ended in April 2019. Data have been collected and are being analyzed. We expect the results of the trial to be published in a peer-reviewed journal in the fall of 2020.

CONCLUSIONS

The greatest strengths of this study are the randomized design, tailored development of the intervention, and access to medical records. The potential limitations are the hierarchy in the prescription process, Hawthorne effect, and biased access to data on signs and symptoms through a UTI diary. The results of this trial could offer a strategy to overcome some of the challenges of increased antibiotic resistance and could have implications in terms of how to handle cases of suspected UTI.
