Abstract
Background
Pharmacists have been co-located in general practice teams to support the quality use of medicines and optimise patient health outcomes. Evidence of the impact of pharmacist-led activities in Australian general practices is sparse.
Aim
This study aimed to evaluate the potential outcomes of pharmacist-led activities in Australian general practices.
Method
A prospective observational study was conducted in eight general practices in the Australian Capital Territory, where each general practice employed a pharmacist on a part-time basis for 18 months. A recommended, but flexible, list of activities was provided for pharmacists. Descriptive information on general practice pharmacist-led activities, collected with an online diary, was analysed. The potential clinical, economic, and organisational impact of pharmacist-led clinical activities was evaluated using the CLinical Economic Organisational (CLEO) tool, with a modified economic dimension.
Results
Nine pharmacists reported 4290 activities over 3918.5 work hours in general practice. Medication management services were the primary clinical activity of pharmacists. In medication reviews, 75% of the pharmacists’ recommendations were fully accepted by general practitioners. Conducting clinical audits, updating patients’ medical records, and providing information to patients and staff were other major activities of pharmacists. Of 2419 clinical activities, around 50% had the potential for a moderate or major positive clinical impact on patients. Sixty-three per cent of activities had the potential to decrease healthcare costs. Almost all the pharmacist-led clinical activities had a positive organisational impact.
Conclusion
Most pharmacist-led clinical activities in general practice had the potential for a positive impact on patients and reduction in healthcare costs, supporting the expansion of this model in Australia.

Introduction
General practices represent an important primary care service that assists the community to manage medical problems and reduce hospital admissions through prevention and early interventions [1]. However, general practices face challenges due to the escalating demand for providing high-quality patient care. The increasing older population, growing burden of chronic diseases, workforce shortages, and reduced general practitioners’ (GPs’) working hours are placing pressure on general practices worldwide [2,3,4]. This suggests the need for team-based care models in general practices to support GPs and improve patient outcomes [5].
Pharmacists have a role to ensure appropriate, safe, and effective drug therapy. Models incorporating pharmacists in general medical practices have been developed to optimise medication use [6]. General practice pharmacists can identify, resolve, prevent, and monitor medication-related problems [7, 8]. In addition to patient-specific medication management services, general practice pharmacists may provide various services, such as quality assurance activities, requesting laboratory tests, providing education to staff and patients, and updating clinical documentation [9, 10]. Incorporating pharmacists in general practices has been studied in many countries. There is a growing international evidence base demonstrating that general practice-based pharmacists can improve medication use through individual patient assessments, population-based interventions and implementing system-level practice enhancements [11,12,13,14,15].
Pharmacists were introduced in Australian general practices in the early 2010s. However, the uptake of pharmacist inclusion in general practice teams has been very slow across the country. There have been several studies conducted in Australia related to pharmacists working in general practices, with limited investigation into pharmacist-led clinical activities, their impact and patient outcomes [7, 10, 16,17,18,19]. There is a need for more research to describe pharmacist-led activities and the impact of those activities in general practices [20].
In the Australian Capital Territory (ACT), a pilot study was conducted to explore the inclusion of pharmacists in general practices through funds from the Capital Health Network (CHN: Primary Health Care Network in the ACT). This pilot study reported general practice pharmacists can engage in a range of activities to support GPs [10]. The study showed that general practice pharmacists can perform medication reviews, provide patient and staff education, assist in the management of asthma, conduct smoking cessation programs, undertake clinical audits, recommend de-prescribing, and contribute to Medicare Benefits Schedule (MBS) activities that generate income for the general practice [10, 21,22,23]. The promising findings of this pilot study informed the expansion of a larger project in multiple locations in the ACT from 2019 to 2021 [24].
Aim
The aim of this study was to evaluate the potential outcomes of pharmacists-led activities in the general practices.
Ethics approval
This study was approved by the Human Research Ethics Committee at the University of Canberra on 20 December 2018 (Ref: HREC 15-235).
Method
Study design and setting
A prospective observational study was conducted in eight general practices in the ACT to evaluate the activities of general practice pharmacists.
Participants and recruitment
The eight general practices were identified by the funder via an expression of interest. The practices were selected to reflect a mix of government-subsidised (“bulk-billing”) and private billing funded practices, at locations across the ACT. The pharmacists (n = 9) were recruited by the general practices between 2019 and 2020. In one general practice, a pharmacist left the project within 5 months and another pharmacist was employed for the remaining time of the contract. The researchers were not involved in the recruitment of general practices or employment of pharmacists.
Intervention
Pharmacists were employed on a part-time basis (15 h per week) for 18 months in the eight general practice sites to provide non-dispensing services. These pharmacists did not have prior experience with the general practice pharmacist role in Australia. A recommended, but flexible, list of activities for pharmacists was developed by the research team based on the previous pilot study and international literature [10, 11, 13, 14] (Table 1). These activities often involved communication with other health professionals both within and external to the practice, including community pharmacies, hospitals, residential aged care facilities (RACFs), and community out-reach services. Each pharmacist was allocated an eight-hour mentorship from a pharmacist who had worked in general practice.
Data collection
Pharmacists’ daily activities were reported using an online electronic diary (Google Forms Online), in which activities were categorised according to the list in Table 1. Miscellaneous activities, such as service development (meeting, planning, booking appointments), professional development and other activities, were categorised separately. In the activity diary, pharmacists were asked to record the estimated time taken to conduct each activity, whether they contacted the patient, details and outcome of the activity, whether the activity saved time for GPs, and the type of claim or MBS item (government-subsidised medical activity) which generated income for the practice and their estimated contribution to the income generated where applicable. One of the researchers (LSD) communicated with the pharmacists monthly to discuss any queries related to data collection. Additionally, pharmacists, practice managers and the research team were invited to participate in quarterly meetings organised by the funder to discuss study activities. Pharmacists’ activities were collected from February 2019 to April 2021.
Data analysis
Coding pharmacists’ activities
Data were de-identified prior to analysis. Pharmacist-led activities were analysed by using an evolving coding system. This system consisted of major codes and sub-codes; major codes were the recommended pharmacist activities (Table 1). Sub-codes included type of activity, referral to the activity, time and contribution to the activity, collaboration, and the outcome of the activity. During data analysis, other activities that did not belong to the above major codes or sub-codes were coded separately. To prevent multiple codes, the activities were categorised according to the definitions provided in Supplemental file 1. The activities were coded independently by two researchers (TS, LSD). Any discrepancies in coding were resolved by a third researcher (SK). Generated income from MBS claimable activities was calculated through the pharmacists’ contribution and AU$ values of MBS items identified at the time of the study [23, 25]. Descriptive statistics were used where applicable to provide an overview of the details of all activities conducted by pharmacists. Categorical measures were presented as the frequencies and percentages, while continuous measures were presented as the mean and standard deviation. The data were analysed using Statistical Package for the Social Sciences (SPSS ver. 27 IBM Corp, Armonk, New York, USA).
Evaluating the potential outcomes of pharmacist-led clinical activities
Pharmacist-led clinical activities in general practice were evaluated by using the CLinical Economic Organisational (CLEO) tool [26]. The multidimensional CLEO tool was based on a review of models and tools to assess pharmacist interventions [27]. This tool has been utilised to explore the impact of pharmacist activities using routine data in the hospital setting [28]. The economic dimension of the CLEO tool was modified to be utilised in the general practice setting (Supplemental file 2).
To test the modified CLEO tool, an assessment was conducted for pharmacist-led activities (n = 33) by selecting the first three activities in the activity diary reflecting each of the 11 different pharmacists’ clinical activities focused on in this study. These pharmacists’ clinical activities included medication reviews, antimicrobial stewardship (AMS), clinical audits, point of care testing (POCT), asthma care, providing education to staff related to medication management of patients, diabetes education, updating medical records, transitions of care, smoking cessation, and vaccination. Pharmacists’ activities related to collaboration with external services, providing basic or general information to staff (e.g. medicine shortages and recalls), service development, and miscellaneous activities were excluded from the evaluation. Inter-rater reliability was tested by checking the intra-class correlation coefficient (ICCA,1) in the assessment [26, 29]. To check inter-rater reliability, the selected pharmacists’ clinical activities were graded independently by three raters (TS, LSD, SK) [30]. The inter-rater reliability for the modified CLEO was good for the clinical (ICCA,1 = 0.77) and economic (ICCA,1 = 0.81) dimensions, and excellent for the organisational dimension (ICCA,1 = 0.99).
Then, two researchers (TS, LSD) independently applied the CLEO criteria to 10% of the pharmacist-led clinical activities reported through the activity diary. Of these activities, discrepancies for only 18 activities (i.e. agreement was more than 90%) were resolved by a third researcher (SK). Based on the analysis, guidance was developed and modified to rate the remaining 90% of activities. Finally, a single investigator (TS) evaluated the remaining 90% of pharmacist-led clinical activities. The modified CLEO tool has been provided in Supplemental file 2.
Results
Description of pharmacist-led activities
Nine pharmacists reported 4290 activities over 3918.5 work hours. After removing 20 duplicate entries, 4270 activities were included in the analysis. There were 1912 (45%) records of patient-facing activities and 2358 (55%) records of non-patient facing activities. The most frequently reported patient-facing activity by pharmacists was the conduct of medication reviews (932; 22%). In medication reviews, 75% of the pharmacists’ recommendations were fully accepted and 10% were partially accepted by GPs (Table 2). The most frequently reported non-patient facing activities were service development (1111; 26%) and collaboration with external services (360; 8%). Overall, 2452 (57%) pharmacists’ activities were directly related to the quality use of medicines.
Pharmacists supported GPs to generate income for the general practice through contribution to MBS claimable activities in medication reviews, POCT, asthma care, diabetes education, transitions of care, and smoking cessation (Table 3).
Potential outcomes of pharmacist-led clinical activities
After excluding the pharmacists’ activities related to collaboration with external services (n = 360), providing general education to staff on guidelines and medicine availability etc. (n = 126), service development (n = 1111), miscellaneous tasks (n = 221) and activities utilised to test the modified CLEO tool (n = 33), 2419 clinical activities conducted by pharmacists were included in the assessment. The clinical activities were related to medication reviews, AMS, clinical audits, POCT, asthma care, providing education to staff, diabetes education, updating medical records, transitions of care, smoking cessation, and vaccination. The potential clinical impact was considered major for 787 (32.5%) clinical activities and moderate for 407 (16.8%) activities (Table 4). Overall, 1528 (63.2%) clinical activities potentially decreased costs to the healthcare system. The organisational impact was positive for almost all the pharmacist-led clinical activities (2367, 97.9%). Examples of case scenarios have been provided in Supplemental file 3.
Discussion
This study assessed pharmacist-led activities and the potential outcomes of clinical activities in general practice. The findings of this study indicate that general practice pharmacists can provide a range of activities that has the potential to benefit patients, decrease healthcare costs for the government, and improve the quality of care. Our findings indicated that 59% of pharmacists’ activities were related to quality use of medicines. These activities included medication management services, such as medication reviews, transitions of care, and asthma care; medication safety initiatives such as clinical audits and POCT; and providing education to patients and general practice staff. Medication reviews were reported previously as the primary function of general practice pharmacists in Australia and other countries [9, 31,32,33,34]. In this study, most of the pharmacists’ recommendations were accepted by GPs and this is consistent with the literature for general practice pharmacists in Australia [20].
One of the roles of general practice-based pharmacists is to improve the quality and safety of prescribing through mechanisms such as practice-based audit and improvement cycles [9, 35]. Pharmacist-led clinical audits, POCT, and updating medical records can improve patient safety and quality of care in the general practice setting. Information provision to general practice staff and patients was also emphasised in this study. Providing education on medicines, devices, and lifestyle modifications (e.g. diabetes education and smoking cessation) were other activities that pharmacists conducted to benefit patients. Patient education, medication management and communication have been identified as key components to improve patient care [36]. Findings of this study have also shown the potential for collaborative activities between the general practice pharmacist and community pharmacy to benefit patients e.g. referring patients for community pharmacy services such as dose aid administration or sleep apnoea tests, delivering opioid maintenance treatment to patients, obtaining medicine availability information for GPs and patients, and solving queries related to medicine adherence or prescriptions.
The CLEO tool was modified to assess the potential clinical, economic, and organisational impact of pharmacist-led clinical activities in general practice [26]. Around 50% of pharmacist-led clinical activities had the potential to cause moderate and major positive clinical impact for patients (i.e., potentially reducing the risk of prolonged hospitalisation, or permanent disability in some cases), and around 63% of activities had the potential to decrease healthcare costs. In Australia, medication-related problems are estimated to cause at least 250,000 annual presentations to emergency departments and unplanned hospital admissions [37]. Furthermore, medication-related problems cost around AU$1.4 billion per annum to the Australian healthcare system [37]. Our findings suggest that general practice pharmacists could improve patient safety and reduce healthcare costs. This finding is consistent with international studies that have reported general practice pharmacists’ outcomes related to improving the quality and safety of medicines use [38,39,40,41].
This study has revealed that almost all the pharmacist-led activities contributed to improving the quality of care in general practice, as per the assessment with the CLEO tool [26]. Pharmacists’ contributions in saving time for GPs, service development, teamwork with other general practice members, and continuity of care were emphasised in a positive organisational impact. Pharmacists also supported GPs to generate income through contribution to MBS claimable items. This finding is consistent with previous studies conducted in Australia and Ireland [19, 23, 39]. The findings may be helpful in informing the development of a funding model for this role in the future.
Strengths and limitations
This prospective observational study provided an overview of general practice pharmacist-led activities, as well as how pharmacists’ activities can contribute to targeting the prevention and resolution of medication-related problems. The study design allowed the longitudinal collection of information relating to multiple outcomes of general practice pharmacists. However, several limitations should be noted. This was a pragmatic observational study that did not include a control group. Furthermore, all general practices that employed a pharmacist in this study were located in the ACT, reflecting one of the states/territories in Australia. This may limit the generalisability of the results as other states or countries have different contextual factors. Pharmacists’ skillset and needs of the individual practice may have had an impact on the number of activities reported by each of the pharmacists. An independent panel was not involved, and GPs or other health professionals in general practice were not included in the panel when assessing the potential impact of pharmacist-led clinical activities. Thus, there is a potential for inherent subjectivity and bias in coding the activities and grading pharmacist-led clinical activities. The activities were self-reported by pharmacists, with the possibility for bias.
Conclusion
Based on an adaptation of the CLEO tool, pharmacists’ activities had an overall positive impact in general practices, and resulted in improved clinical outcomes for patients, reduced healthcare costs, saved time for GPs, and improved continuity of care and teamwork in general practice. The study’s findings, while positive, require confirmation in a randomised controlled trial.
