Evidence-based Medication knowledge Brokers in Residential Aged CarE (EMBRACE): protocol for a helix-counterbalanced randomised controlled trial

INTRODUCTION

Clinical practice guidelines recommend against the routine use of psychotropic medications in residential aged care facilities (RACFs). Knowledge brokers are individuals or groups who facilitate the transfer of knowledge into practice. The objective of this trial is to evaluate the effectiveness and cost-effectiveness of using knowledge brokers to translate Australia's new Clinical Practice Guidelines for the Appropriate Use of Psychotropic Medications in People Living with Dementia and in Residential Aged Care.

METHODS AND ANALYSIS

The Evidence-based Medication knowledge Brokers in Residential Aged CarE (EMBRACE) trial is a helix-counterbalanced randomised controlled trial. The 12-month trial will be conducted in up to 19 RACFs operated by four Australian aged care provider organisations in Victoria, New South Wales, Western Australia and Queensland. RACFs will be randomised to receive three levels of implementation strategies (knowledge broker service, pharmacist-led quality use of medications education activities and distribution of the Guidelines and supporting materials) across three medication contexts (antipsychotics, benzodiazepines and antidepressants). Implementation strategies will be delivered by an embedded on-site aged care pharmacist working at a system level across each participating RACF. All RACFs will receive all implementation strategies simultaneously but for different medication contexts. The primary outcome will be a composite dichotomous measure of 6-month RACF-level concordance with Guideline recommendations and good practice statements among people using antipsychotics, benzodiazepines and antidepressants for changed behaviours. Secondary outcomes will include proportion of residents with Guideline concordant use of antipsychotics, benzodiazepines and antidepressants measured at the RACF-level and proportion of residents with psychotropic medication use, hospitalisation, falls, falls with injury, polypharmacy, quality of life, activities of daily living, medication incidents and behavioural incidents measured at the RACF-level.

DISCUSSION

The EMBRACE trial investigates a novel guideline implementation strategy to improve the safe and effective use of psychotropic medications in RACFs. We anticipate that the findings will provide new information on the potential role of knowledge brokers for successful and cost-effective guideline implementation.

Embedded on-site aged care pharmacists in Australia: Insights from early adopters of a new workforce model

OBJECTIVE

To explore the roles of early adopters of Australia's embedded on-site pharmacist model in supporting quality use of medications in residential aged care facilities (RACFs).

METHODS

Qualitative semistructured interviews were conducted with 15 pharmacists working as embedded on-site pharmacists, or beyond the scope of traditional consultant pharmacist roles in Australian RACFs. Interviews were audio-recorded, transcribed and thematically analysed independently by two investigators using an inductive approach. Deductive analysis was also undertaken using a knowledge broker framework: knowledge manager, linkage agent and capacity builder.

RESULTS

Dominant themes were roles and benefits of embedded pharmacists, factors associated with success and challenges. Roles and benefits included (1) resident-level interventions and an enhanced ability to provide collaborative outcome-focussed resident-centred care, including timely input and follow-up, and improved relationships with residents, family and interdisciplinary team; and (2) system-level interventions such as contributing to clinical governance and quality improvement. Factors associated with success included personal capabilities and approach of the pharmacist, and organisational culture and sector-wide support. Challenges included pharmacist workforce shortages, perceived lack of pharmacist readiness and difficulty determining an appropriate service model. Deductive coding demonstrated roles of embedded pharmacists were consistent with all three activities of a knowledge broker.

CONCLUSIONS

This study highlights the resident- and system-level roles and benefits of embedded on-site pharmacists, and provides a framework for defining this emerging workforce model in Australian RACFs.

The effect of frailty on post-discharge management and outcomes of acute glycaemic crises: Analysis of admissions for hypoglycaemia and hyperglycaemia in Australia

OBJECTIVE

To describe changes in glucose-lowering drug (GLD) dispensing by frailty status for people with diabetes following admission for hypoglycaemia or hyperglycaemia.

METHODS

This study included all people with probable type 2 diabetes in the state of Victoria, Australia, admitted to hospital for hypoglycaemia (n = 2,506 admissions) or hyperglycaemia (n = 1,693) between 1 July 2013 and 29 June 2017. Frailty was defined via the Hospital Frailty Risk Score (HFRS). We examined differences in dispensing of GLDs in the year before and after admission using linear regression models adjusted for age, sex, comorbidities, and socioeconomic status.

RESULTS

Dispensing of GLDs decreased following hypoglycaemia admission. Decreased dispensing was strongly associated with frailty status, with a change in mean annual GLD dispensing count of -4.11 (-5.05, -3.17) for an HFRS of 15 vs. -0.99 (-1.47, -0.50) for an HFRS of 0. Changes were greatest for metformin and sulfonylureas. Following hyperglycaemia admission, the mean number of annual GLD dispensings increased, with a smaller increase with increasing frailty: 2.44 (1.32, 3.56) for an HFRS of 0 vs. 1.16 (0.18, 2.14) for an HFRS of 15.

CONCLUSIONS

Frailty was associated with more conservative diabetes medication management following hypoglycaemia and hyperglycaemia admissions.

Roles and effectiveness of knowledge brokers for translating clinical practice guidelines in health-related settings: a systematic review

BACKGROUND

Poor translation of clinical practice guidelines (CPGs) into clinical practice is a barrier to the provision of consistent and high-quality evidence-based care. The objective was to systematically review the roles and effectiveness of knowledge brokers (KBs) for translating CPGs in health-related settings.

METHODS

MEDLINE, Embase, PsycINFO and CINAHL Plus were searched from 2014 to June 2022. Randomised controlled trials (RCTs), controlled and uncontrolled preintervention and postintervention studies involving KBs, either alone or as part of a multicomponent intervention, that reported quantitative postintervention changes in guideline implementation in a healthcare setting were included. A KB was defined as an intermediary who facilitated knowledge translation by acting in at least two of the following core roles: knowledge manager, linkage agent or capacity builder. Specific activities undertaken by KBs were deductively coded to the three core roles, then common activities were inductively grouped. Screening, data extraction, quality assessment and coding were performed independently by two authors.

RESULTS

16 studies comprising 6 RCTs, 8 uncontrolled precomparisons-postcomparisons, 1 controlled precomparison-postcomparison and 1 interrupted time series were included. 14 studies (88%) were conducted in hospital settings. Knowledge manager roles included creating and distributing guideline material. Linkage agent roles involved engaging with internal and external stakeholders. Capacity builder roles involved audit and feedback and educating staff. KBs improved guideline adherence in 10 studies (63%), had mixed impact in 2 studies (13%) and no impact in 4 studies (25%). Half of the RCTs showed KBs had no impact on guideline adherence. KBs acted as knowledge managers in 15 (94%) studies, linkage agents in 11 (69%) studies and capacity builders in all studies.

CONCLUSION

Knowledge manager and capacity builder roles were more frequently studied than linkage agent roles. KBs had mixed impact on translating CPGs into practice. Further RCTs, including those in non-hospital settings, are required.

A systematic review of opioid prevalence in Australian residential aged care facilities

OBJECTIVE

To systematically review the prevalence of opioid prescribing, dispensing and administration in Australian residential aged care facilities (RACFs).

METHODS

MEDLINE, Embase, CINAHL, AgeLine, Web of Science Core Collection, InformIT and International Pharmaceutical Abstracts (inception to September 2021) were searched for studies reporting opioid prevalence in Australian RACFs. Regular and as-required (i.e. pro re nata, PRN) opioid uses were considered. Screening, data extraction and quality assessment were performed independently by two review authors.

RESULTS

Twenty-three studies (n = 286,141 residents) reported opioid prevalence, of which 16 provided overall regular or PRN prescribing, dispensing or administration data. Five studies reported 28%-34% of residents were prescribed regular opioids over assessment periods ranging from one week to one month. Five studies reported 11%-42% of residents were prescribed PRN opioids over assessment periods ranging from one week to 30 months. Three studies reported 27%-50% of residents were dispensed an opioid over 12 months. Five studies reported 21%-29% were administered both regular and PRN opioids over 24 hours. Two studies reported 22%-42% of residents were administered PRN opioids over 1 week to 12 months. Two studies reported 6%-13% of residents were using doses >100 mg oral morphine equivalents/day.

CONCLUSIONS

Up to half of the residents were dispensed opioids over 12 months. The prevalence of opioid prescribing, dispensing and administration was highly variable, suggesting the potential value of opioid quality indicators and analgesic stewardship interventions to ensure opioid appropriateness.
