Introduction Managing medication regimens is one of the most complex and burdensome tasks performed by older people, and can be prone to errors. People living with dementia may require medication administration assistance from formal and informal caregivers. Simplified medication regimens maintain the same therapeutic intent, but have less complex instructions and administration schedules. This protocol paper outlines a study to determine the feasibility of a multicomponent intervention to simplify medication regimens for people receiving community-based home care services.
Methods and analysis This is a non-randomised pilot and feasibility study. Research nurses will recruit 50 people receiving community-based home care services. All participants will receive the intervention from a clinical pharmacist, who will undertake medication reconciliation, assess each participant’s capacity to self-manage their medication regimen and apply a structured tool to identify opportunities for medication simplification. The pharmacist will communicate recommendations regarding medication simplification to registered nurses at the community-based home care provider organisation. The primary outcome will be a description of study feasibility (recruitment and retention rates, protocol adherence and stakeholder acceptability). Secondary outcomes include the change in number of medication administration times per day, medication adherence, quality of life, participant satisfaction, medication incidents, falls and healthcare utilisation at 4 months.
Ethics and dissemination Ethical approval was obtained from the Monash University Human Research Ethics Committee and the community-based home care provider organisation’s ethical review panel. Research findings will be disseminated to consumers and caregivers, health professionals, researchers and healthcare providers through the National Health and Medical Research Council Cognitive Decline Partnership Centre and through conference presentations, lay summaries and peer-reviewed publications. This study will enable an improved understanding of medication management and administration among people receiving community-based home care services. This study will inform the decision to proceed with a randomised controlled trial to assess the effect of this intervention.

Strengths and limitations of this study
This study will provide new information regarding the burden of medication administration among older people receiving community-based home care services and inform future strategies to improve medication management.
Quantitative and qualitative approaches will be used to comprehensively assess study outcomes.
The outcomes to be assessed by this study are relevant to people receiving community-based home care services and their informal caregivers, community-based home care providers, clinicians and policy-makers.
A potential limitation is that study participants will be recruited from one service provider which means findings may not be generalisable to all people receiving community-based home care services.
Older people often have complex medication regimens to manage multiple chronic diseases. For example, two-thirds of Australians aged 75 years and older use five or more medications on a daily basis.1 The overall prevalence of medication use in the community setting is increasing, as evidenced by a doubling in the median number of medications prescribed to adults aged 65 years and over in the USA, from 2 to 4 medications, between 1988 and 2010.2 The increasing prevalence of polypharmacy, together with a variety of factors such as increased availability of non-oral formulations and medication delivery devices, and special administration instructions for certain medications (eg, crush, take with food) means that medication management is one of the most complex medical tasks performed by community-dwelling older people and their formal and informal caregivers.3
Medication regimens with multiple administration times can be particularly burdensome for older people and/or informal caregivers.3 Having a complex medication regimen is also associated with a range of adverse events among community-dwelling older people, including medication self-administration errors,4 unplanned hospitalisations5 and all-cause mortality.6 It is possible that undertaking medication regimen simplification could lead to a reduction in the number of times that medications need to be administered, and may reduce some of the burden associated with medication management in the community setting. Medication regimen simplification refers to the process of consolidating the number of administration times through strategies such as administering medications at the same time, using long acting in preference to short-acting formulations, and switching from multiple single ingredient to combination formulations, where possible.7
Evidence from previous studies suggests that people living with dementia and their informal caregivers often require practical support from health professionals to deal with medication-related issues.8 In accord, supporting people living with dementia and caregivers to simplify medication regimens for individuals living with dementia has been identified as an unmet priority.3 9 Simplifying medication regimens for community-dwelling people with dementia is particularly important because people living with dementia use at least as many, if not more, medications than people without dementia.10 11 Because dementia can further impact the ability to plan, organise and undertake medication management,12 informal caregivers are often involved in medication management for people living with dementia. For example, in the US National Health and Aging Trends Study and National Study of Caregiving, informal caregivers who cared for a person living with dementia were 64% more likely to assist with ordering medications and 76% more likely to keep track of medications in comparison to caregivers for older people without dementia.13 Previous research suggests that people living with dementia and their informal caregivers are interested in interventions to reduce unnecessary challenges associated with medication use.14
An ongoing, multidisciplinary randomised controlled trial (RCT) is investigating an intervention to simplify medication regimens in South Australian residential aged care facilities.7 However, unlike in residential aged care settings, informal caregivers play a major role in determining medication administration schedules for community-dwelling people for whom they provide care.15 Furthermore, few people receiving community-based home care services have the direct support of a registered nurse to oversee all medication management and administration. Simplifying medication regimens is of interest to community-based home care service providers because multiple medication administration times may affect how much assistance older people require16 and because people who transition from care at home to residential aged care have increasingly complex medication regimens that are time consuming and costly to administer.17 However, the feasibility of simplifying medication regimens in this setting is currently unknown.
The aim of this pilot and feasibility study is to determine the feasibility of a multicomponent intervention to simplify medication regimens for people receiving community-based home care services. A quantitative and qualitative feasibility assessment will be undertaken to inform the decision to proceed with a RCT to assess the effect of this intervention.
The primary objectives of the pilot and feasibility study are as follows:
To determine how many people accept the invitation to participate in the study.
To determine how many participants receive the intervention.
To estimate recruitment and refusal rates, and 4-month follow-up rates.
To explore, qualitatively, the acceptability of the recruitment processes, assessments, intervention delivery and secondary outcome measures with key stakeholders.
To investigate the acceptability of the intervention to stakeholders by determining whether there are changes to medication regimens at 4 months after study entry.
The secondary objectives are:
To measure key domains for secondary outcome measures including percentage of participants who are able to self-report data for assessments, assessment completion rates by research nurses, missing data, estimates, variances and 95% CIs for any comparisons.
To collect and synthesise secondary outcome data to inform the sample size estimation for a subsequent RCT, should this be feasible.
Methods and analysis
This pilot and feasibility study is a non-randomised study and all participants will receive the intervention. The pilot and feasibility study will be consistent with guidance proposed by Eldridge et al18 and O’Cathain et al,19 and reported using the Standard Protocol Items: Recommendations for Interventional Trials reporting template (online supplementary file 1).20 A mixed methods approach will be undertaken to assess feasibility.
Governance and consultation
The research team comprises nurses, pharmacists and a geriatrician with expertise in aged care research. The research team also comprises representatives from the community-based home care provider. The service provider is an active research partner, and informed the protocol design and implementation of the research.
The Project Governance Committee will comprise the chief investigators and nominated representatives from the organisation providing the community-based home care services. This committee will monitor compliance with the study protocol, data collection and data analysis throughout the study period. The Stakeholder Reference Group is a separate committee that will be comprised of health professionals, community-based home care services staff, people who receive aged care services and informal caregivers. The chief investigators and the community-based home care provider will determine membership of the Stakeholder Reference Group. The purpose of this group is to support the chief investigators to engage with a range of relevant stakeholders with different types of expertise and backgrounds related to the research study. The chief investigators will work closely with the community-based home care provider to conduct face-to-face consultations with other relevant stakeholders, including people who receive aged care services and informal caregivers, during the pre-intervention period.
Patient and public involvement
The research team conducted face-to-face consultations with the formal Consumer and Carer Reference Group maintained by the overarching aged care organisation to discuss the design, recruitment processes and conduct of the current pilot and feasibility study. This group comprises 10–12 people who either receive community-based home care services or residential aged care services from the aged care organisation, or have a family member who receive these services. This group was established in 2013 and meets regularly to provide advice on issues relating to services provided by the aged care organisation. The research team also consulted the consumer and carer members of the Stakeholder Reference Group of a related study.7 Feedback on the relevance of the outcome measures to be assessed in this study for older people living in the community was also sought during the face-to-face consultations.
This pilot and feasibility study will involve people receiving a government-funded community-based home care service. These services include Commonwealth Home Support Programme services or Home Care Packages. Commonwealth Home Support Programme services provide entry-level ongoing support services and are targeted at older Australians who require assistance with one or more instrumental activities of daily living but can otherwise manage most aspects of their daily living.21 Individuals who apply for a Home Care Package undergo a structured assessment process, and are subsequently allocated to receive a funding package that ranges from basic care needs (level 1) through to high care needs (level 4). Both the Commonwealth Home Support Programme services and Home Care Packages are funded by the Australian Government and subsidise an approved community-based home care provider to provide services that meet each individual’s care need.22 Services can include assistance with meals, transport, personal care and medication management. Development of community-based home care services is consistent with the Government’s objective of providing services that facilitate older people to remain living independently in the community.17 Nearly one in five Australians receiving a government-subsidised community aged care service package are living with dementia.23
The participants will be 50 people receiving Commonwealth Home Support Programme services or Home Care Packages in metropolitan and rural South Australia. Individuals who are able to participate in structured assessments in English and are prescribed medication(s) to be administered two or more times daily on a regular basis are eligible. This means that a person prescribed one medication two times per day on a regular basis is potentially eligible to participate.
People estimated to have less than 3 months to live and those deemed by health professionals and caregivers to be medically unstable (eg, experiencing delirium) will be excluded. People may also be excluded for any other reason at the discretion of their regular treating clinicians or informal caregivers.
Recruitment and consent process
Research nurses were contracted by the community-based home care provider organisation and therefore had good knowledge of organisational processes, policies and procedures. A training package adapted from a related study conducted in residential aged care11 was used to train the research nurses in the consent process for the present study, and to train the research nurses and project pharmacist to use the data collection tools and administer assessments.
Participant recruitment commenced on 16 July 2018 and the first participant was enrolled on 22 August 2018. Research nurses liaised with community-based home care provider staff to obtain a list of all people receiving medication administration assistance from the organisation and who were potentially eligible. Research nurses then mailed information about the study to all people receiving medication administration assistance from the provider organisation. Research nurses then conducted follow-up telephone calls with all people who were mailed information to determine eligibility for the study, to provide verbal information about the study, and to seek written informed consent to participate. This process was performed in accordance with the ethical principles for involving people with cognitive impairment in research studies outlined in the Australian National Statement for Ethical Conduct in Human Research.24
For people who had the capacity to provide consent to participate, written consent was obtained directly from that individual. Online supplementary file 2 provides a model consent form. When the person was unable to provide written informed consent to participate, consent to participate was sought from the person’s guardian, next of kin or significant other. For people with enduring power of guardianship, the research nurses explained as much about the study as possible to the person, and sought written informed consent from the guardian.
The Dementia Australia Guide to Dementia Friendly Language was used when writing about dementia or the impact of supporting a person living with dementia in study materials.25 Research nurses were trained to use the principles outlined in the Dementia Australia ‘Talk to Me’ tips for talking to people living with dementia during discussions with all participants, particularly when speaking with people living with dementia and when administering the Dementia Severity Rating Scale in third-party informant interviews.26 Using appropriate language that is accurate, respectful, inclusive, empowering and non-stigmatising is important when writing or talking about dementia.25
Baseline data collection
The research nurses will collect all data for each participant at baseline and 4 months after study entry as outlined in table 1. The research nurses will speak with the participant and/or their informal caregivers, and liaise with the community pharmacy, general medical practitioner (GP) and the community-based home care provider to obtain information about prescribed, dispensed and non-prescription medications. Demographic and clinical data will be sourced from the community-based home care provider nursing progress notes. The research nurses will contact the participant’s GP to source information from the participant’s medical record, including current and past health conditions, adverse drug reactions, demographic and social information, any hospital discharge summaries and details of any Home Medicines Reviews (HMRs) performed in the 4 months prior to study entry. Other data will be collected via participant self-report and the research nurses conducting interviews with third-party informants (table 1). Participants who are unable to complete assessments outlined in table 1 are still eligible for inclusion in the study. Third-party informants will be staff members or informal caregivers who have known the participant for at least 2 weeks. Research nurses will be trained to ask informants to advise the research nurses if they feel they do not know the participant well enough to answer any specific questions.
The intervention will be delivered after recruitment and baseline data collection (table 2) by a project pharmacist who is accredited to perform HMRs. The three main components of the intervention are outlined in table 2.
The first step in the intervention will involve the project pharmacist undertaking medication reconciliation. Medication reconciliation is the process of developing the ‘best possible medication history’ that outlines which medications the participant actually takes, the dose form, the dose of each medication and the corresponding administration schedule.27 28 This step is necessary because discrepancies often exist between medication records maintained by aged care providers, GPs, pharmacies and participants.29 For example, medications prescribed by medical practitioners other than the regular GP, complementary and alternative medications and over-the-counter medications may be omitted from GP medication records. Conversely, discontinued medications may continue to be included in GP medication records. A preliminary medication history will be compiled by the project pharmacist prior to visiting each participant. The preliminary medication history will be based on information collected from the participant’s community pharmacy, GP and community-based home care provider by the research nurse. This information will be verified by the project pharmacist during a participant interview to ensure that any medications independently managed by the participant and not included on the community pharmacy, GP or community-based home care provider list are included in the final version of the best possible medication history prepared by the project pharmacist. This step will ensure that the subsequent recommendations to simplify the medication regimen are based on a full and accurate understanding of the participant’s current medication regimen. The importance of having an accurate medication history available prior to medication simplification is outlined in the Medication Regimen Simplification Guide for Residential Aged CarE (MRS GRACE).30
Capacity to self-manage
The second step in the intervention will involve the project pharmacist assessing the participant’s ability to self-manage their own medication regimen by applying the Drug Regimen Unassisted Grading Scale (DRUGS).31 This is because it is important to understand a person’s capacity to self-manage their medication regimen before recommending changes to their medication administration routine. The DRUGS criteria have four assessed domains for each medication taken that considers identification, access, dosage and timing.31 It has demonstrated inter-rater reliability and test–retest reliability when used among people aged 70 years and older residing in retirement villages.31 The DRUGS criteria require the participant to be able to correctly identify the medication, dose and administration times. The participant is then asked to demonstrate the process of accessing the dose by opening the medication container, obtaining the dose from a dose administration aid (eg, blister pack, dosette box), or correctly using the device (eg, insulin injection or metered-dose inhaler). This process is repeated for each medication in the participant’s medication regimen. The DRUGS criteria will be scored by the project pharmacist in accordance with the published literature31 and the resulting score will be expressed as a percentage to provide a numerical score on a scale of 0–100. If after applying the DRUGS criteria the project pharmacist believes the participant does not have sufficient capacity to self-manage the participant’s medication regimen, this will be brought to the attention of a registered nurse employed by the community-based home care provider. After discussing with the registered nurse, the project pharmacist may contact the participant’s regular GP and pharmacist to discuss management strategies if the participant is self-managing part or all of their medication regimen and the pharmacist believes the participant does not have sufficient capacity to do so.
Medication regimen simplification
The third step in the intervention will involve the application of a five-step, implicit structured tool to support decisions to simplify medication regimens. The pharmacist will use a modified version of MRS GRACE that was originally designed, validated and tested in the residential aged care setting.7 30 In order to modify the tool for application in the community setting, a multidisciplinary stakeholder meeting was convened in December 2017. Stakeholders included members of the expert panel who informed the development of MRS GRACE, and members of the research governance committee and stakeholder reference committee for the pilot and feasibility study. Minor revisions to the wording of the MRS GRACE tool and associated explanatory statement to support application in the community setting were made based on consultations and feedback from these stakeholders.
The project pharmacist’s recommendations to simplify each participant’s medication regimen will be informed by the medication reconciliation and assessment of participant’s capacity to self-manage medications, medication adherence and the participant’s clinical and functional profile. The participant’s willingness to have their medication regimen simplified will be assessed during the pharmacist interview. The project pharmacist will prepare a written report for the community-based home care provider that includes the reconciled best possible medication history and a ‘medication management statement’ comprising assessments of adherence, capacity to self-manage and recommendations for simplification. The project pharmacist will then discuss the opportunity for regimen simplification with a registered nurse employed by the community-based home care provider. After discussing with the registered nurse, the project pharmacist may contact the participant’s regular GP and pharmacist where necessary to discuss strategies for simplifying the medication regimen. Strategies recommended by the pharmacist may include a change in medication administration time, formulation (eg, switching to a combination product or slow release preparation) or active ingredient. Recommended changes in medication administration times will be approved by the registered nurse employed by the community-based home care service providing care to the participant or the participant’s GP prior to implementation. The GP will have the opportunity to review all other recommended simplification strategies before implementation and adjust the medication regimen accordingly. The participant’s GP and/or community-based home care services nursing staff will ensure the participant or their guardian, next of kin or significant other are involved in the decision-making process before simplification strategies are implemented. At the end of the ‘simplification’ interview, the project pharmacist may provide the participant with a copy of their current medication list where clinically indicated or requested, and if no further recommendations for simplification require consideration by the community-based home care services nursing staff or the GP. If the project pharmacist identifies a clinically significant medication-related problem that poses risk of harm to the participant, this will be brought to the attention of the home care service provider and the participant’s regular GP. If the project pharmacist believes that the participant would benefit from an HMR, this recommendation will be communicated in writing to the registered nurse employed by the community-based home care provider, who will forward this recommendation to the participant’s regular GP.
Participants will remain eligible for all usual care services during the study period. These services include, but are not limited to, clinical and care services provided by the community-based home care provider, community pharmacist, GP, medical specialists and other health service utilisation (eg, HMRs).
The primary outcome will be a narrative description of study feasibility, including recruitment and retention, protocol adherence and stakeholder acceptability. The primary outcome will be assessed using a mixed methods approach.
A document analysis will be undertaken to determine the number of people who were mailed information about the study, the number of people approached by telephone to participate in the study, the number of people who met the inclusion criteria and the number(s) of people who provided informed consent, received the intervention and completed 4-month follow-up. Quantitative data will be collected from field notes maintained by the project team, recruitment logs, the medication simplification intervention reports written by the project pharmacist, meeting minutes and email correspondence.
A qualitative approach will be used to determine (1) protocol adherence and adaptations, (2) acceptability of the recruitment processes, assessments, intervention delivery and secondary outcome measures and (3) barriers and enablers to intervention delivery. Facilitators and barriers important for the design of a subsequent RCT will also be explored. Qualitative data will be generated from small face-to-face focus groups or semistructured interviews undertaken after the intervention with approximately 10–15 key stakeholders in total. People participating in the study, family members who provided third-party consent for a person to participate, the research nurses, the project pharmacist, staff employed by the community-based home base provider organisation and GPs will be invited to participate. At least three study participants will be interviewed, including at least one person for whom simplification was not possible, one person for whom medication simplification was recommended but not implemented, and a person for whom at least one recommendation was implemented. The interview guide will comprise questions modified from that used in previous related research.7 All focus groups and semistructured interviews will be conducted face to face by two members of the research team. The sessions will be audiotaped, transcribed and analysed thematically using the procedures outlined by Braun and Clarke.32
Secondary outcomes include the change in the number of medication administration times over a 24 hours period for regular medications at 4 months post study entry. This outcome was selected because (1) the main focus of medication regimen simplification is to reduce the number of dosing times and (2) the majority of medication simplification recommendations made by pharmacists in other studies11 30 would lead to a reduction in the number of dosing times when implemented.
Medication administration times are defined as each separate occasion that medication is administered. It is anticipated that dose times may be expressed differently across different data sources used to develop the best possible medication history. For example, dose times may be reported using a 24 hours clock (eg, 06:00, 12:00, 18:00, 22:00), time slots (eg, 07:00–10:00, 12:00–14:00) or words (eg, breakfast, lunch, dinner, bedtime). These times will be standardised in our dataset and considered by the project pharmacist when ascertaining medication administration times. The number of distinct medication administration times will be counted and reported numerically. A hypothetical example of a medication regimen at baseline and 4-month follow-up that illustrates a change in the number of medication administration times is depicted in table 3.
Other secondary outcomes at 4-month follow-up will be the total number of individual medication doses administered over a 24 hour period for regular medications; adherence to the medication regimen measured with the Self-Efficacy for Appropriate Medication use Scale33; quality of life using the Quality of Life in Alzheimer’s Disease Scale34; participant satisfaction using the Short Assessment of Patient Satisfaction35; falls and medication incidents, as outlined in table 1.
The healthcare utilisation outcomes will be ambulance call-outs, emergency department visits, hospital admissions, admissions to residential aged care facilities and all-cause mortality (table 1). We will also consider the changes recommended by the project pharmacist, pharmacist time and time spent administering medications.
Recommended changes to simplify the regimen will be extracted from the project pharmacist’s deidentified report to the GP. These changes will consider the dose forms and medications that are most commonly recommended to be changed to simplify the regimen.
Pharmacist time measured using the project pharmacist’s record of the amount of time spent reconciling medications, identifying opportunities for simplification, generating recommendations and communicating with key stakeholders (eg, the participant, the participant’s family, caregivers, GPs and community pharmacists). This information will be recorded prospectively as the project pharmacist delivers the intervention.
Time spent administering medications will be estimated. This estimate will be informed by current medication administration practices by the community-based home care provider. This estimate will account for various factors including the number of medications administered, administration times, dosage formulations and dose administration aids.
Where possible, we will compare the baseline medication history held by the community-based home care provider with the baseline best possible medication history independently prepared by the project pharmacist and identify, document and classify the clinical significance of any discrepancies. Any suspected and actual adverse events will be reported and analysed. These outcomes will inform the data collection methods for the planned subsequent RCT.
As this is a pilot and feasibility study, a formal sample size calculation is not required. We will aim to recruit a sample size of 50 participants to assess feasibility across a diverse range of participants including those with and without a dementia diagnosis, different care needs or frailty status and with or without informal carers. We estimate that this target sample size would be greater than 10% of the number of people required for a future RCT. This target sample size is in keeping with the median target sample size of 30 (IQR 20–45) people for pilot studies, 36 (IQR 25–50) people for feasibility studies and 49 (IQR 36–61) people for pilot and feasibility studies observed in an audit of 79 pilot and feasibility RCTs registered on the United Kingdom Clinical Research Network database in 2012.36
Quantitative data will be imported into the SAS Statistical Software (SAS Institute) for analysis and reported using descriptive statistics. Changes in the secondary outcome measures at follow-up will be assessed using the paired t-test (continuous variables) and McNemar’s test (categorical variables).
Study participants will be assigned a unique code to enable data linkage throughout follow-up. All data will be entered into an electronic management system by research team members who are trained in data entry. Medications will be classified using WHO Anatomical and Therapeutic Chemical classification. To ensure accurate data entry, a second member of the research team will check data entry for the first 10 participants, and for a random 10% sample of records entered after that. Data collection and study conduct will be monitored through weekly meetings with the research team, representatives from the community-based home care provider organisation, research nurses and project pharmacist to ensure protocols are implemented consistently. Data collected as part of this study will be treated confidentially and stored securely at the Centre for Medicine Use and Safety, Faculty of Pharmacy and Pharmaceutical Sciences, Monash University. Only study investigators based at the Centre for Medicine Use and Safety, Faculty of Pharmacy and Pharmaceutical Sciences, Monash University will have access to the final dataset.
This study will improve understanding of medication administration among older people receiving community-based home care services and inform strategies to improve medication management in this setting. Extensive stakeholder consultation has informed the study design and protocol development. An existing validated tool for use in the residential aged care setting was modified for use in the community setting, and it will be applied in this community-based study.
The intervention in this study comprises medication reconciliation, assessment of the ability of an individual to self-manage their own medication regimen, and identifying opportunities to simplify the medication regimen. This study will seek to establish the probable ‘active components’ of the intervention37 and to determine appropriate and acceptable outcome measures so that these parameters can be measured during a subsequent RCT. As such, all people included in this pilot and feasibility study will receive the intervention. A limitation with this approach is that the randomisation method for application in a subsequent RCT cannot be tested in the present study.
The intervention will be delivered by a single project pharmacist with considerable expertise in medication reconciliation. However, there are tools available to support a standardised approach to medication history taking38 and a more structured approach will be considered in the design of a future RCT. The intervention will provide important information on the amount of time spent by the project pharmacist to deliver the intervention, but a limitation is that we will not be able to capture the time spent by the community-based home care provider staff, GPs and community pharmacists who will be involved in the implementation of the pharmacist’s recommendations.
Study participants will be recruited from a cohort receiving community-based home care services from one service provider, so the study findings may not be generalisable, particularly to older people living independently without caregiver support. Asking people to self-report medication self-efficacy and adherence is another potential study limitation. However, previous studies of people with and without dementia in aged care settings have demonstrated a considerable proportion of people living with dementia are able to self-report outcomes39 and it is important to determine on an individual basis whether an individual is able to self-report outcomes. In the present study, a third-party informant may be interviewed when a participant is not able to undertake assessments themselves. Research nurses will also liaise with the participant’s community pharmacist to provide a recent dispensing history and this will aid insight into adherence to prescription medications.
Complex medication regimens are often challenging for older people to manage, and considerable support with medication management is often needed.3 Complex regimens are associated with medication errors and poor adherence, as well as poor health outcomes.4–6 This study will determine the feasibility of a multicomponent intervention to simplify medication regimens for people receiving community-based home care services, which will inform the development and implementation of a subsequent RCT, should this be feasible.
