Global contributions of pharmacists during the COVID-19 pandemic.

Throughout the SARS-CoV-2 (COVID-19) global pandemic, pharmacists were rarely mentioned as essential frontline health care providers by the news media, the public, or politicians. Around the world, pharmacists are working on the frontlines of health care every day providing essential health care services during the pandemic. Pharmacists are medication experts providing patient care in a variety of settings including hospitals, clinics, community pharmacies, long-term care, physician offices, and national and public health. In this paper, we describe how pharmacists from high and low-middle income countries contributed to essential patient care and well-being of the public during the COVID-19 pandemic. While the news media, the public, and politicians often overlooked pharmacists as essential frontline health care providers, we hope that this list of contributions by pharmacists from nine countries in this article can help to change this perspective.

A pharmacist-led prospective antibiotic stewardship intervention improves compliance to community-acquired pneumonia guidelines in 39 public and private hospitals across South Africa.

INTRODUCTION: Pharmacists in low-middle-income countries (LMIC) are few and lack antibiotic stewardship (AS) training. The ability was assessed of non-specialised pharmacists to implement stewardship interventions and improve adherence to the South African community-acquired pneumonia (CAP) guideline in public and private hospitals. METHODS: This was a multicentre, prospective cohort study of adult CAP patients hospitalised between July 2017 and July 2018. A CAP bundle was developed of seven process measures (diagnostic and AS) that pharmacists used to audit compliance and provide feedback. CAP bundle compliance rates and change in outcome measures [mortality, length of stay (LOS) and infection-related (IR)-LOS] during pre- and post-implementation periods were compared. RESULTS: In total, 2464 patients in 39 hospitals were included in the final analysis. Post-implementation, overall CAP bundle compliance improved from 47·8% to 53·6% (confidence interval [CI] 4·1-7·5, p<0·0001), diagnostic stewardship compliance improved from 49·1% to 54·6% (CI 3·3-7·7, p<0·0001) and compliance with AS process measures from 45·3% to 51·6% (CI 4·0-8·6, p<0·0001). Improved compliance with process measures was significant for five (2 diagnostic, 3 AS) of seven components: radiology, laboratory, antibiotic choice, duration and intravenous to oral switch. There was no difference in mortality between the two phases, [4·4%(55/1247) vs. 3·9%(47/1217); p=0·54], median LOS or IR LOS 6·0 vs. 6·0 days (p=0·20) and 5·0 vs. 5·0 days (p=0·40). CONCLUSION: Non-specialised pharmacists in public and private hospitals implemented stewardship interventions and improved compliance to SA CAP guidelines. The methodology of upskilling and a shared learning stewardship model may benefit LMIC countries.

From guidelines to practice: a pharmacist-driven prospective audit and feedback improvement model for peri-operative antibiotic prophylaxis in 34 South African hospitals.

Background: Few data exist on the implementation of process measures to facilitate adherence to peri-operative antibiotic prophylaxis (PAP) guidelines in Africa. Objectives: To implement an improvement model for PAP utilizing existing resources, in order to achieve a reduction in surgical site infections (SSIs) across a heterogeneous group of 34 urban and rural South African hospitals. Methods: A pharmacist-driven, prospective audit and feedback strategy involving change management and improvement principles was utilized. This 2.5 year intervention involved a pre-implementation phase to test a PAP guideline and a 'toolkit' at pilot sites. Following antimicrobial stewardship committee and clinician endorsement, the model was introduced in all institutions and a survey of baseline SSI and compliance rates with four process measures (antibiotic choice, dose, administration time and duration) was performed. The post-implementation phase involved audit, intervention and monthly feedback to facilitate improvements in compliance. Results: For 70 weeks of standardized measurements and feedback, 24 206 surgical cases were reviewed. There was a significant improvement in compliance with all process measures (composite compliance) from 66.8% (95% CI 64.8-68.7) to 83.3% (95% CI 80.8-85.8), representing a 24.7% increase ( P < 0.0001). The SSI rate decreased by 19.7% from a mean group rate of 2.46 (95% CI 2.18-2.73) pre-intervention to 1.97 post-intervention (95% CI 1.79-2.15) ( P = 0.0029). Conclusions: The implementation of process improvement initiatives and principles targeted to institutional needs utilizing pharmacists can effectively improve PAP guideline compliance and sustainable patient outcomes.

Antimicrobial stewardship across 47 South African hospitals: an implementation study.

BACKGROUND: The available data on antimicrobial stewardship programmes in Africa are scarce. The aims of this study were to assess the implementation of an antimicrobial stewardship programme in a setting with limited infectious disease resources. METHODS: We implemented a pharmacist-driven, prospective audit and feedback strategy for antimicrobial stewardship on the basis of a range of improvement science and behavioural principles across a diverse group of urban and rural private hospitals in South Africa. The study had a pre-implementation phase, during which a survey of baseline stewardship activities was done. Thereafter, a stepwise implementation phase was initiated directed towards auditing process measures to reduce consumption of antibiotics (prolonged duration, multiple antibiotics, and redundant antibiotic coverage), followed by a post-implementation phase once the model was embedded in each hospital. The effect on consumption was assessed with the WHO index of defined daily doses per 100 patient-days, and the primary outcome (change in antibiotic consumption between phases) was assessed with a linear mixed-effects regression model. FINDINGS: We implemented and assessed the antimicrobial stewardship programme between Oct 1, 2009, and Sept 30, 2014. 116 662 patients receiving antibiotics at 47 hospitals during 104 weeks of standardised measurement and feedback, were reviewed, with 7934 interventions by pharmacists recorded for the five targeted measures, suggesting that almost one in 15 prescriptions required intervention. 3116 (39%) of 7934 pharmacist interventions were of an excessive duration. The antimicrobial stewardship programme led to a reduction in mean antibiotic defined daily doses per 100 patient-days from 101·38 (95% CI 93·05-109·72) in the pre-implementation phase to 83·04 (74·87-91·22) in the post-implementation phase (p<0·0001). INTERPRETATION: Health-care facilities with limited infectious diseases expertise can achieve substantial returns through pharmacist-led antimicrobial stewardship programmes and by focusing on basic interventions. FUNDING: None.

Antimicrobial Stewardship with Pharmacist Intervention Improves Timeliness of Antimicrobials Across Thirty-three Hospitals in South Africa.

INTRODUCTION: Ensuring timely administration of antimicrobials is critical in the management of patients with infections. Mortality increases by 7.6% for every hour of delay in the administration of antimicrobial therapy in patients with sepsis. The time elapsed from the written antibiotic order to actual intravenous administration or 'hang-time' can often be several hours due to logistics within the hospital. Our purpose is to evaluate the change in compliance with administering antimicrobials within an hour of prescription after implementation of a national antibiotic stewardship pharmacist-driven hang-time process improvement protocol. METHODS: This was a prospective multicenter study in 33 South African hospitals from 1 July 2013-30 August 2014. Two pilot sites established the mechanism for noninfectious disease pharmacists to make interventions and document hang-time data. Following this, a hang-time compliance assessment was initiated using the tools of healthcare improvement spread methodology. This consisted of five stages and an implementation toolkit was developed. The pharmacist study coordinator was responsible for implementation, the development of an implementation toolkit and real-time coordination of data with monthly feedback to all sites. RESULTS: A total of 32,985 patients who received intravenous antibiotics were assessed for hang-time compliance with first doses of new antibiotic orders. Over the 60-week period, 21,069 patients received antibiotics within an hour following prescription and were assessed as hang-time compliant. The change in improvement of hang-time compliance following implementation of a pharmacist-driven hang-time process improvement protocol was 41.2% pre-intervention week 1 (164/398) to 78.4% post-intervention week 60 (480/612; P < 0.0001). Pharmacists reviewed and evaluated twice as many patients during the final 4 weeks (1680) compared to the first 4 weeks (834; P < 0.0001). CONCLUSION: Noninfectious disease pharmacists can significantly improve the timely administration of antimicrobials and contribute to low-hanging-fruit antimicrobial stewardship initiatives within a hospital system in a resource-limited country.
