Community pharmacist's preparedness to provide patient-centred care in Saudi Arabia.

Background: Community pharmacy practice in Saudi Arabia is evolving and needs to be at par with the developed world. Community pharmacists can play a vital role in bridging gaps in the delivery of healthcare services by providing patient-centred care to patients and contributing toward the healthcare transformation plan of vision 2030 of Saudi Arabia. The present study is aimed at evaluating the knowledge, attitude, and practices of community pharmacists in delivering patient-centred care services. Method: A nationwide cross-sectional survey using a validated and pre-tested 27-item self-reported questionnaire was conducted amongst 301 (86.4% male, 13/6% female) community pharmacists from all regions of Saudi Arabia. Both descriptive and inferential analysis was employed using the SPSS version, with 0.05 as the level of significance. Results: Community pharmacists from chain pharmacy groups, female gender and staff community pharmacists had statistically better overall practice standards, knowledge, and attitude to conduct patient-centred care services (p less than 0.01). The majority of community pharmacists would expect extra remuneration and participation in structured professional skills development programs to provide patient-centred care efficiently. Inaccessibility of patient data from healthcare facilities, the unavailability of informative literature, and administrative workload were among the barriers cited in delivering patient-centred care. Conclusion: The study findings show that community pharmacists could play a significant role in providing patient-centred care and contribute to the achievement of the healthcare reform agenda of Saudi Arabia. However, some obstacles must be overcome before this practice can be shifted, including the introduction of a formalized continuing professional development program, financial incentives, and a decrease in the administrative burden on pharmacists. The results of this study may help policymakers in Saudi Arabia better comprehend the country's existing approach to community pharmacy practice.

Magnetic micromixing for highly sensitive detection of glyphosate in tap water by colorimetric immunosensor.

Glyphosate is the most widely used herbicide in the world and, in view of its toxicity, there is a quest for easy-to-use, but reliable methods to detect it in water. To address this issue, we realized a simple, rapid, and highly sensitive immunosensor based on gold coated magnetic nanoparticles (MNPs@Au) to detect glyphosate in tap water. Not only the gold shell provided a sensitive optical transduction of the biological signal - through the shift of the local surface plasmon resonance (LSPR) entailed by the nanoparticle aggregation -, but it also allowed us to use an effective photochemical immobilization technique to tether oriented antibodies straight on the nanoparticles surface. While such a feature led to aggregates in which the nanoparticles were at close proximity each other, the magnetic properties of the core offered us an efficient tool to steer the nanoparticles by a rotating magnetic field. As a result, the nanoparticle aggregation in presence of the target could take place at higher rate (enhanced diffusion) with significant improvement in sensitivity. As a matter of fact, the combination of plasmonic and magnetic properties within the same nanoparticles allowed us to realize a colorimetric biosensor with a limit of detection (LOD) of 20 ng∙L-1.
