Background Drug-related problems (DRPs) are a major burden on the Australian healthcare system. Community pharmacists are in an ideal position to detect, prevent, and resolve these DRPs. Objective To develop and validate an easy-to-use documentation system for pharmacists to classify and record DRPs, and to investigate the nature and frequency of clinical interventions undertaken by Australian community pharmacists to prevent or resolve them. Setting Australian community pharmacies. Method The DOCUMENT classification system was developed, validated and refined during two pilot studies. The system was then incorporated into software installed in 185 Australian pharmacies to record DRPs and clinical interventions undertaken by pharmacists during a 12-week trial. Main outcome measure The number and nature of DRPs detected within Australian community pharmacies. Results A total of 5,948 DRPs and clinical interventions were documented from 2,013,923 prescriptions dispensed during the trial (intervention frequency 0.3%). Interventions were commonly related to Drug selection problems (30.7%) or Educational issues (23.7%). Pharmacists made an average of 1.6 recommendations per intervention, commonly relating to A change in therapy (40.1%) and Provision of information (34.7%). Almost half of interventions (42.6%) were classified by recording pharmacists as being at a higher level of clinical significance. Conclusion The DOCUMENT system provided pharmacists with a useful and easy-to-use tool for recording DRPs and clinical interventions. Results from the trial have provided a better understanding of the frequency and nature of clinical interventions performed in Australian community pharmacies, and lead to a national implementation of the system.

Background Drug-related problems (DRPs) are a major burden on health care systems. Community pharmacists are ideally placed to detect, prevent, and resolve these DRPs. Objective: To determine the number and nature of DRPs detected and clinical interventions performed by Australian community pharmacists, using an electronic system. Methods: An electronic documentation system was designed and integrated into the existing dispensing software of 186 pharmacies to allow pharmacists to record details about the clinical interventions they performed to prevent or resolve DRPs. Participating pharmacies were randomly allocated to 3 groups: group 1 had documentation software, group 2 had documentation software plus a timed reminder to document interventions, and group 3 had documentation software, a timed reminder, and an electronic decision support prompt. Pharmacists classified DRPs, entered recommendations they made, and estimated the clinical significance of the intervention. An observational substudy that included pharmacies without any documentation software was completed to verify intervention rates. Results: Over 12 weeks, 531 participating pharmacists recorded 6230 clinical interventions from 2,013,923 prescriptions, with a median intervention rate of 0.23% of prescriptions. No significant differences were seen between the 3 groups that used documentation software; as expected, however, the pharmacies that used this software had a significantly higher documentation rate compared to the pharmacies without documentation software. The most common interventions were related to drug selection problems (30.8%) and educational issues (24.4%). Recommendations were often related to a change in therapy (40.0%), and 41.6% of interventions were self-rated as highly significant. Drug groups most commonly subject to an intervention included antibiotics, glucocorticoids, nonsteroidal antiinflammatory drugs, and opioids. Conclusions: The documentation system allowed for the determination of the frequency and types of DRPs, as well as the recommendations made to resolve them In community pharmacy practice. Use of the software, including its electronic prompts, significantly increased the documentation of interventions by pharmacists.

AIM To evaluate the effect of a computerized decision support prompt regarding high-dose proton pump inhibitor (PPI) therapy on prescribing and medication costs. METHODS A prompt activated on dispensing high-dose esomeprazole or pantoprazole was implemented in 73 of 185 pharmacies. Anonymized prescription data and a patient survey were used to determine changes in prescribing and associated medication costs. RESULTS The pharmacist-recorded PPI intervention rate per 100 high-dose PPI prescriptions was 1.67 for the PPI prompt group and 0.17 for the control group (P < 0.001). During the first 28 days of the trial, 196 interventions resulted in 34 instances of PPI step-down, with 28 of these occurring in PPI prompt pharmacies. Cost savings attributable to the prompt were AUD 7.98 (£4.95) per month per PPI prompt pharmacy compared with AUD 1.05 (£0.65) per control pharmacy. CONCLUSION The use of electronic decision support prompts in community pharmacy practice can promote the quality use of medicines.

Introduction Drug‐related problems (DRPs) are associated with significant morbidity and mortality, with most DRPs thought to be preventable. Community pharmacists can detect and either prevent or resolve many of these DRPs. A survey‐based clinical knowledge measurement tool was designed and validated to estimate a community pharmacists clinical knowledge and ability to detect and appropriately resolve DRPs.

Background Despite increasing interest in antimicrobial stewardship (AMS), little is known about the related practices and perceptions of community pharmacists. Objective To develop and validate a questionnaire to measure the current practices of, and barriers to community pharmacists’ participation in AMS. Setting Community pharmacists in Tasmania, Australia. Method A questionnaire to explore AMS knowledge, current practices and perceptions of community pharmacists was developed. It was designed after rigorous literature review, expert opinion, and feedback from a group of community pharmacists. A convenience sample of 140 Tasmanian community pharmacists was used for this study. Cronbach’s alpha and exploratory factor analysis (EFA) were used for reliability and validity. The questionnaire was hosted online, a link to which was sent by invitation e-mails, fax and post to community pharmacists in Tasmania, Australia. Main outcome measure Current AMS practices, perceived importance, barriers and facilitators of AMS. Results Eighty-five pharmacists responded to the survey yielding a response rate of 61%. EFA identified one factor solution for each of three perceptions scales and showed acceptable reliability. The Cronbach’s alpha of perceived importance-understanding was 0.699, perceived importance-motivating was 0.734, perceived support from GPs was 0.890, operational barriers was 0.585, general facilitators was 0.615. Most pharmacists reported that they counselled patients on adverse effects (86%), drug interactions (94%), and allergies (96%). In contrast, less than half (43%) intervened with prescribers regarding antibiotic selection. Lack of training, lack of access to patients’ records, limited interactions with general practitioners and absence of a reimbursement model were major barriers limiting community pharmacists’ participation in AMS. Conclusion The questionnaire was of acceptable reliability and validity; a larger study will further contribute in its reliability and validity. Future studies utilising the questionnaire at national and international level may provide further insights into the determinants of community pharmacist’s involvement in AMS.
