Implementation factor mapping of a pilot study of point-of-care C-reactive protein testing for respiratory tract infections in community pharmacy.

Background: Explicit consideration of implementation factors in community pharmacy service development may facilitate widespread implementation and sustainability. Objectives: This study involved mapping the methodology for the pilot study of point-of-care C-reactive protein (CRP) testing to support pharmacists' management of respiratory tract infections in Western Australian pharmacies against an implementation factor framework, focussing on the resources and training program provided to participating pharmacy staff. Methods: Phase 1 involved post hoc mapping of the pilot study methodology against the framework previously described by Garcia-Cardenas et al.; phase 2 was an a priori evaluation of the resources and training program, involving pre-training, post-training, and post-pilot questionnaires administered to pharmacists and pharmacy assistants/interns. A mixed model analysis compared pharmacists' responses at the three time points. Results: Employment of comprehensive strategies to optimise service feasibility and sustainability was demonstrated across the five domains of 'professional service', 'pharmacy staff', 'pharmacy', 'local environment' and 'system'; further consideration of 'consumer' or 'patient' factors is needed to address issues such as patient refusal. Study pharmacists (n = 10) and pharmacy assistants/interns (n = 5) reported high levels of satisfaction with the training (100% 'good'/'excellent'). Pharmacists reported significantly improved attitudes towards, confidence in, and knowledge about CRP testing and service provision from pre- to post-training (p < 0.05). Positive perceptions were maintained at the post-pilot time point. Conclusions: Post hoc mapping of implementation factors highlighted potential strengths and deficiencies of the current service model. Systematic, prospective mapping, coupled with strategies to explicitly emphasise the patient perspective, may have value in optimising service implementation or modifying future service delivery models.

Point-of-care C-reactive protein testing service for respiratory tract infections in community pharmacy: a qualitative study of service uptake and experience of pharmacists.

Background Targeted interventions in community pharmacies, such as point-of-care C-reactive protein testing, could reduce inappropriate antimicrobial consumption in patients presenting with symptoms of respiratory tract infections, although data regarding Australian pharmacists' perspectives on its provision are limited. Aim To explore pharmacists' experiences and perspectives of point-of-care C-reactive protein testing, including barriers and facilitators, influencing service provision and uptake. Method A point-of-care C-reactive protein testing service for patients presenting with respiratory tract infection symptoms was trialled in five purposively selected community pharmacies in metropolitan Western Australia. Two pharmacists from each pharmacy participated in one-to-one semi-structured telephone interviews, regarding pharmacist demographics, pharmacy characteristics, experience with the point-of-care C-reactive protein service and training/resources. Interviews were audio-recorded and transcribed. Data were imported into NVivo for thematic analysis. Results Interview durations ranged from 28.2 to 60.2 min (mean: 50.7 ± 10.2 min). Of the five themes which emerged, participants reported the point-of-care C-reactive protein testing was simple, fast, reliable and accurate, assisted their clinical decision-making and contributed to antimicrobial stewardship. A major factor facilitating service provision and uptake by consumers was the accessibility and credibility of pharmacists. Barriers included time constraints and heavy documentation. Participants believed there was a public demand for the service. Conclusion Given the global antimicrobial resistance crisis, pharmacists have an important role in minimising the inappropriate use of antimicrobials. The point-of-care C-reactive protein service was readily accepted by the public when offered. However, ensuring efficient service delivery and adequate remuneration are essential for its successful implementation.

Point-of-care C-reactive protein testing to support the management of respiratory tract infections in community pharmacy: A feasibility study.

BACKGROUND: Point-of-care (POC) C-reactive protein (CRP) testing is employed in European primary care settings to differentiate viral from bacterial respiratory tract infections (RTIs) the latter, requiring referral for antibiotics. This service has yet to be trialled in Australian community pharmacy to support over-the-counter RTI management. OBJECTIVES: To evaluate the feasibility, based on clinical and operational outcomes, of POC CRP testing to support Western Australian community pharmacists' management of RTIs. METHODS: Patients with RTI signs and symptoms were recruited from June-August 2019 at 5 community pharmacies. Trained pharmacists made recommendations based on participants' POC CRP levels and routine clinical assessment. Participants completed questionnaires and telephone follow-ups on Days 3 (by pharmacists) and 5 (by researchers) post-testing. Service provision and uptake were assessed in 3 separate weekly tally sheets. RESULTS: Clinical outcomes: CRP levels among the 131 participants recruited were: < 5 mg/L (bacterial infection unlikely; n = 60; 45.8%); 5-19 mg/L (bacterial infection possible if suggestive routine assessment; n = 52; 39.7%) and 20-100 mg/L (bacterial infection likely if suggestive routine assessment; n = 19; 14.5%). Pharmacists' management included over-the-counter medicines (131, 100%), self-care advice (125, 95.4%) and immediate general practitioner (GP) referral (15, 11.5%). Sixty-five percent (76/117) of participants had recovered by Day 5. Operational outcomes: The services was provided in 21.2% of eligible RTI presentations, representing a service uptake rate of 28.1%. Post-CRP testing, 50.9% (58/114) of participants had changed perceptions regarding their need for antibiotics, with 14.3% (16/112) subsequently intending to seek a GP prescription. Consumer satisfaction was high (100%) and most participants (93.4%, 123/131) would utilise the service again. CONCLUSIONS: POC CRP testing was a feasible and well-accepted strategy to facilitate community pharmacy as a triage point for RTI. Consumer confidence in the pharmacists' advice, supported by CRP testing, potentially reduced unnecessary GP visits and antibiotic prescribing.
