Root Cause Analysis to Identify Medication and Non-Medication Strategies to Prevent Infection-Related Hospitalizations from Australian Residential Aged Care Services

Surveillance of Antimicrobial Use in Long-Term Care Facilities: An Antimicrobial Mapping Survey

OBJECTIVES

To explore antimicrobial management processes in Australian residential aged care facilities (RACFs), including antimicrobial prescribing, supply, administration, and documentation to inform surveillance activities.

DESIGN

Voluntary, online cross-sectional survey.

SETTING AND PARTICIPANTS

The survey was disseminated to all South Australian RACFs (n = 237) seeking participation from an infection prevention and control lead (preferred respondent), a nurse or senior RACF staff member, or an aged care pharmacist.

METHODS

The survey was open during May-June 2023. Questions aimed to understand clinical and medication management systems, sources of antimicrobial prescription and supply, management by external health care providers and documentation of antimicrobial administration. A process map of antimicrobial management in RACFs was developed.

RESULTS

Of the 54 RACFs included in the analysis (29.5% response rate), most used an electronic clinical documentation system (74.1%) or a hybrid electronic paper-based system (22.2%). Medication charts were either electronic (81.0%), hybrid (5.6%), or paper-based (13.0%). Antimicrobials were prescribed by the resident's usual general practitioner, but also by locums, hospital or specialist physicians, nurse practitioners, virtual care physicians, and dentists. Oral, topical, and inhaled antimicrobial formulations were usually supplied by community pharmacies, and intravenous formulations were predominately supplied by hospitals for administration by outreach nurses. Almost all RACFs (96.2%) had imprest stock of antimicrobials that included both oral and intravenous formulations. Antimicrobials were predominately administered by an enrolled nurse or a registered nurse.

CONCLUSIONS AND IMPLICATIONS

Antimicrobial management in RACFs is complex, particularly during care transitions. Multiple prescribers and sources of antimicrobials, use of different systems for clinical documentation, particularly by external health care providers, and clinical governance relating to imprest supplies were identified as key areas where medication management could be improved. Addressing these gaps will facilitate comprehensive, real-time antimicrobial surveillance in Australian RACFs.

Post-Stroke Infections: Insights from Big Data Using Clinical Data Warehouse (CDW)

This study analyzed a digitized database of electronic medical records (EMRs) to identify risk factors for post-stroke infections. The sample included 41,236 patients hospitalized with a first stroke diagnosis (ICD-10 codes I60, I61, I63, and I64) between January 2011 and December 2020. Logistic regression analysis was performed to examine the effect of clinical variables on post-stroke infection. Multivariable analysis revealed that post-stroke infection was associated with the male sex (odds ratio [OR]: 1.79; 95% confidence interval [CI]: 1.49-2.15), brain surgery (OR: 7.89; 95% CI: 6.27-9.92), mechanical ventilation (OR: 18.26; 95% CI: 8.49-44.32), enteral tube feeding (OR: 3.65; 95% CI: 2.98-4.47), and functional activity level (modified Barthel index: OR: 0.98; 95% CI: 0.98-0.98). In addition, exposure to steroids (OR: 2.22; 95% CI: 1.60-3.06) and acid-suppressant drugs (OR: 1.44; 95% CI: 1.15-1.81) increased the risk of infection. On the basis of the findings from this multicenter study, it is crucial to carefully evaluate the balance between the potential benefits of acid-suppressant drugs or corticosteroids and the increased risk of infection in patients at high risk for post-stroke infection.

Detecting Acute Deterioration in Older Adults Living in Residential Aged Care: A Scoping Review

OBJECTIVES

To explore models, processes, or tools implemented in residential aged care (RAC) to support registered nurses (RNs) to identify and respond to the acute deterioration of residents.

DESIGN

Scoping literature review of English Language articles published in peer reviewed journals.

SETTINGS AND PARTICIPANTS

Studies were conducted in RAC facilities providing long-term 24-hour medical, nursing, and social care for people age 65 years or older with age-related disability.

METHODS

We completed a MESH term and key word search of MEDLINE, Embase, CINAHL, PubMed, and Google Scholar. Included studies had (1) part of the intervention based in RAC; (2) had a direct impact on RAC day to day practice; and (3) contained or provided access to the detail of the intervention. Data was charted by author, date, country, study design and the components, genesis, and efficacy of the methods used to identify and respond to acute deterioration.

RESULTS

We found 46 studies detailing models of care, clinical patterns of acute deterioration, and deterioration detection tools. It was not possible to determine which element of the models care had the greatest impact on RN decision making. The clinical patterns of acute deterioration painted a picture of acute deterioration in the frail. There was limited evidence to support the use of existing deterioration detection tools in the RAC population.

CONCLUSION AND IMPLICATIONS

We found no straight forward systematic method to support RAC RNs to identify and respond to the acute deterioration of residents. This is an important practice gap. The clinical pattern of acute deterioration described in the literature has the potential to be used for the development of a tool to support RAC RNs to identify and respond to the acute deterioration of residents.

Stakeholders' perspectives of mobile x-ray services in support of healthcare-in-place in residential aged care facilities: a qualitative study

Background

There is interest in reducing avoidable emergency department presentations from residential aged care facilities (RACF). Mobile x-ray services may enable the delivery of healthcare in residential aged care facilities. Accordingly, the Australian Government in November 2019 introduced a Medicare Benefit Schedule rebate providing for a ‘call-out’ fee payable to radiology service providers.

This study aims to understand stakeholder perspectives on the benefits of mobile x-ray services and the factors influencing their adoption by RACFs.

Design, setting, participants

Twenty-two semi-structured interviews were conducted between October 2020 and February 2021 with a range of stakeholders involved in healthcare delivery to residents: a) general practitioners; b) emergency department clinicians; c) paramedic clinicians; d) a hospital avoidance clinician; e) radiology clinicians and managers; and f) aged care clinicians and managers. Thematic analysis was conducted.

Results

Mobile x-ray services were considered valuable for RACF residents. Lack of timely general practitioner in-person assessment and referral, as well as staffing deficits in residential aged care facilities, reduces optimal use of mobile x-ray services and results in potentially unnecessary hospital transfers.

Conclusions

The use of mobile x-ray services, as a hospital avoidance strategy, depends on the capacity of RACFs to provide more complex healthcare-in-place. However, this requires greater access to general practitioners for in-person assessment and referral, adequate staffing numbers and appropriately skilled nursing staff within residential aged care facilities.

Contribution of facility level factors to variation in antibiotic use in long-term care facilities: a national cohort study

OBJECTIVES

To examine national variation in systemic antibiotic use in long-term care facilities (LTCFs) and identify facility characteristics associated with antibiotic utilization.

METHODS

This retrospective cohort study included 312 375 residents of 2536 Australian LTCFs between 2011 and 2016. LTCFs were categorized as low, medium or high antibiotic use facilities according to tertiles of DDDs of systemic antibiotics dispensed per 1000 resident-days. Multivariable logistic regression estimated the associations between facility characteristics (ownership, size, location, medication quality indicator performance, prevalence of after-hours medical practitioner services) and antibiotic use (low versus high).

RESULTS

LTCFs in the lowest and highest antibiotic use categories received a median of 54.3 (IQR 46.5-60.5) and 106.1 (IQR 95.9-122.3) DDDs/1000 resident-days, respectively. Compared with not-for-profit LTCFs in major cities, government-owned non-metropolitan LTCFs were less likely to experience high antibiotic use [adjusted OR (aOR) 0.47, 95% CI 0.24-0.91]. LTCFs with 69-99 residents were less likely to experience high antibiotic use (aOR 0.69, 95% CI 0.49-0.97) than those with 25-47 residents annually. Greater prevalence of medical practitioner services accessed after-hours was associated with high antibiotic use [aOR 1.10 (per 10% increase in after-hours services), 95% CI 1.01-1.21]. South Australian LTCFs (aOR 2.17, 95% CI 1.38-3.39) were more likely, while Queensland (0.43, 95% CI 0.30-0.62) and Western Australian (aOR 0.34, 95% CI 0.21-0.57) LTCFs were less likely to experience high antibiotic use than New South Wales LTCFs.

CONCLUSIONS

Considerable facility level variation in systemic antibiotic use was observed across Australian LTCFs. Identification of facility characteristics associated with antibiotic use provides a basis for targeted stewardship initiatives.
