Process Evaluation of the SImplification of Medications Prescribed to Long-tErm Care Residents (SIMPLER) Cluster Randomized Controlled Trial: A Mixed Methods Study

Simplifying medication regimens for residents of aged care facilities: Pharmacist and physician use of a structured five-step medication simplification tool

BACKGROUND

Pharmacist-led medication regimen simplification using a structured approach can reduce unnecessary medication regimen complexity in residential aged care facilities (RACFs), but no studies have investigated simplification by different health professionals, nor the extent to which simplification is recommended during comprehensive medication reviews.

OBJECTIVES

To compare medication regimen simplification opportunities identified by pharmacists, general medical practitioners (GPs), and geriatricians and to determine if pharmacists identified simplification opportunities during routinely conducted comprehensive medication reviews in RACFs for these same residents.

METHODS

Three pharmacists, three GPs and three geriatricians independently applied the Medication Regimen Simplification Guide for Residential Aged CarE (MRS GRACE) to medication data for 83 residents taking medications at least twice daily. Interrater agreement was calculated using Fleiss's kappa. Pharmacist medication review reports for the same 83 residents were then examined to identify if the pharmacists conducting these reviews had recommended any of the simplification strategies.

RESULTS

Overall, 77 residents (92.8 %) taking medications at least twice daily could have their medication regimen simplified by at least one health professional. Pharmacists independently simplified 53.0-77.1 % of medication regimens (Κ = 0.60, 95%CI 0.46-0.75, indicating substantial agreement), while GPs simplified 74.7-89.2 % (Κ = 0.44, 95%CI 0.24-0.64, moderate agreement) and geriatricians simplified 41.0-66.3 % (Κ = 0.30, 95%CI 0.16-0.44, fair agreement). No simplification recommendations were included in the reports previously prepared by pharmacists as part of the comprehensive medication reviews undertaken for these residents.

CONCLUSION

Pharmacists, GPs, and geriatricians can all identify medication regimen simplification opportunities, although these opportunities differ within and between professional groups. Although opportunities to simplify medication regimens during comprehensive medication reviews exist, simplification is not currently routinely recommended by pharmacists performing these reviews in Australian RACFs.

Assessing implementation fidelity of an on-site pharmacist intervention within Australian residential aged care facilities: A mixed methods study

BACKGROUND

An on-site pharmacist (OSP) intervention was implemented which sought to improve medication management within residential aged care facilities (RACFs) in the Australian Capital Territory, Australia. The objectives of this mixed methods study were to evaluate the implementation fidelity of the OSP intervention and to determine the moderating factors which influenced delivery of this intervention.

METHODS

This convergent parallel mixed methods study was underpinned by Hasson's conceptual framework for implementation fidelity. Implementation fidelity for seven intervention RACFs was quantitatively assessed using three quantitative data sets: (1) range of OSP intervention activities delivered; (2) random sample of 10% of medication reviews assessed for quality; (3) proportion of residents who received at least one medication review. Semi-structured interviews (n = 14) with managers and OSPs across the intervention RACFs were conducted to identify moderating factors which may have influenced OSP intervention delivery.

RESULTS

The OSP intervention was generally delivered as intended with overall medium levels of implementation fidelity. This delivery was supported by a range of facilitation strategies with most participants perceiving that the intervention was delivered to a high standard. RACF managers and OSPs were mostly well engaged and responsive. A number of potential barriers (including the part-time OSP role, COVID-19 pandemic, RACFs spread out over a large area with significant distance between resident dwellings) and facilitators (including the pharmacist support meetings, OSPs who took time to establish relationships, RACF managers who actively supported OSPs and worked with them) for OSP intervention delivery were identified which have potential implications for the roll out of OSPs within Australian RACFs.

CONCLUSION

In this study, the implementation fidelity of OSP intervention delivery was assessed with overall medium levels of fidelity found across the intervention RACFs. This suggested that the OSP intervention can generally be delivered as intended in real world RACFs. OSP intervention delivery was influenced by a range of moderating factors, some of which posed barriers and others which facilitated the OSP intervention being delivered as intended.

The multimorbidity collaborative medication review and decision making (MyComrade) study: a pilot cluster randomised trial in two healthcare systems

BACKGROUND

While international guidelines recommend medication reviews as part of the management of multimorbidity, evidence on how to implement reviews in practice in primary care is lacking. The MyComrade (MultimorbiditY Collaborative Medication Review And Decision Making) intervention is an evidence-based, theoretically informed novel intervention which aims to support the conduct of medication reviews for patients with multimorbidity in primary care.

AIM

The pilot study aimed to assess the feasibility of a definitive trial of the MyComrade intervention across two healthcare systems (Republic of Ireland (ROI) and Northern Ireland (NI)).

DESIGN

A pilot cluster-randomised controlled trial was conducted (clustered at general practice level), using specific progression criteria and a process evaluation framework.

SETTING

General practices in the ROI and NI.

PARTICIPANTS

Eligible practices were those in defined geographical areas who had GP's and Practice Based Pharmacists (PBP's) (in NI) willing to conduct medication reviews. Eligible patients were those aged 18 years and over, with multi morbidity and on ten or more medications.

INTERVENTION

The MyComrade intervention is an evidence-based, theoretically informed novel intervention which aims to support the conduct of medication reviews for patients with multimorbidity in primary care, using a planned collaborative approach guided by an agreed checklist, within a specified timeframe.

OUTCOME MEASURES

Feasibility outcomes, using pre-determined progression criteria, assessed practice and patient recruitment and retention and intervention acceptability and fidelity. Anonymised patient-related quantitative data, from practice medical records and patient questionnaires were collected at baseline, 4 and 8 months, to inform potential outcome measures for a definitive trial. These included (i) practice outcomes-completion of medication reviews; (ii) patient outcomes-treatment burden and quality of life; (iii) prescribing outcomes-number and changes of prescribed medications and incidents of potentially inappropriate prescribing; and (iv) economic cost analysis. The framework Decision-making after Pilot and feasibility Trials (ADePT) in conjunction with a priori progression criteria and process evaluation was used to guide the collection and analysis of quantitative and qualitative data.

RESULTS

The recruitment of practices (n = 15) and patients (n = 121, mean age 73 years and 51% female), representing 94% and 38% of a priori targets respectively, was more complex and took longer than anticipated; impacted by the global COVID-19 pandemic. Retention rates of 100% of practices and 85% of patients were achieved. Both practice staff and patients found the intervention acceptable and reported strong fidelity to the My Comrade intervention components. Some practice staff highlighted concerns such as poor communication of the reviews to patients, dissatisfaction regarding incentivisation and in ROI the sustainability of two GPs collaboratively conducting the medication reviews. Assessing outcomes from the collected data was found feasible and appropriate for a definitive trial. Two progression criteria met the 'Go' criterion (practice and patient retention), two met the 'Amend' criterion (practice recruitment and intervention implementation) and one indicated a 'Stop - unless changes possible' (patient recruitment).

CONCLUSION

The MyComrade intervention was found to be feasible to conduct within two different healthcare systems. Recruitment of participants requires significant time and effort given the nature of this population and the pairing of GP and pharmacist may be more sustainable to implement in routine practice.

Contextual factors influencing complex intervention research processes in care homes: a systematic review and framework synthesis

Background

Care homes are complex settings to undertake intervention research. Barriers to research implementation processes can threaten studies’ validity, reducing the value to residents, staff, researchers and funders. We aimed to (i) identify and categorise contextual factors that may mediate outcomes of complex intervention studies in care homes and (ii) provide recommendations to minimise the risk of expensive research implementation failures.

Methods

We conducted a systematic review using a framework synthesis approach viewed through a complex adaptive systems lens. We searched: MEDLINE, Embase, CINAHL, ASSIA databases and grey literature. We sought process evaluations of care home complex interventions published in English. Narrative data were indexed under 28 context domains. We performed an inductive thematic analysis across the context domains.

Results

We included 33 process evaluations conducted in high-income countries, published between 2005 and 2019. Framework synthesis identified barriers to implementation that were more common at the task and organisational level. Inductive thematic analysis identified (i) avoiding procedural drift and (ii) participatory action and learning as key priorities for research teams. Research team recommendations include advice for protocol design and care home engagement. Care home team recommendations focus on internal resources and team dynamics. Collaborative recommendations apply to care homes’ individual context and the importance of maintaining positive working relationships.

Discussion

Researchers planning and undertaking research with care homes need a sensitive appreciation of the complex care home context. Study implementation is most effective where an intervention is co-produced, with agreed purpose and adequate resources to incorporate within existing routines and care practices.
