The Impacts of Clinical Pharmacists' Interventions on Clinical Significance and Cost Avoidance in a Tertiary Care University Hospital in Oman: A Retrospective Analysis

Economic impact and clinical benefits of clinical pharmacy interventions: A six-year multi-center study using an innovative medication management tool

BACKGROUND

Increasing healthcare costs, particularly in Low- and Middle-Income Countries (LMICs) like Egypt, highlight the need for rational economic strategies. Clinical pharmacy interventions offer potential benefits by reducing drug therapy problems and associated costs, thereby supporting healthcare system sustainability.

OBJECTIVE

This study evaluates the economic impact and clinical benefits of clinical pharmacy interventions in four tertiary hospitals in Egypt by implementing an innovative tool for medication management, focusing on cost avoidance and return on investment (ROI), while accounting for case severity and drug therapy problem (DTP) resolution.

METHODS

Utilizing a digital tool, cost avoidance was assessed by considering the severity of patient cases and the effectiveness of clinical pharmacists' interventions in resolving identified DTPs. Additionally, ROI was calculated by incorporating both full-time equivalent (FTE) and non-FTE costs to evaluate the overall economic impact of clinical pharmacy services over a six-year period across four tertiary care hospitals in Egypt.

RESULTS

Over six years, a total of 492,612 patients were reviewed, leading to 19,240 comprehensive clinical pharmacy interventions. These interventions achieved an 88.63% resolution of DTPs, significantly reducing patient risk by preventing adverse DTP consequences, resulting in a total cost avoidance of EGP 265.32 million (USD 8.60 million) and an average ROI of 7.6 (760%). This underscores the substantial economic impact of clinical pharmacy services, particularly in LMICs and countries transitioning to universal health insurance coverage, where cost efficiency and patient safety are critical.

CONCLUSION

This study underscores the importance of clinical pharmacy interventions in improving healthcare outcomes and generating significant economic benefits, particularly in low- and middle-income countries. By accounting for case severity and the level of DTP consequences, along with the efficiency of clinical pharmacist-led interventions in resolving DTPs, the economic impact of these services can be more accurately evaluated. These findings are essential for informing policy decisions, highlighting the critical role of clinical pharmacy services in supporting healthcare systems facing economic constraints.

Inappropriate Polypharmacy and the Need for Comprehensive Medication Management Service

Documentation and classification of hospital pharmacist interventions: A scoping review

The practice of documenting pharmacist interventions (PIs) has been endorsed by many hospital pharmacists' societies and organizations worldwide. Current systems for recording PIs have been developed to generate data on better patient and healthcare outcomes, but harmonization and transferability are apparently minimal. The present work aims to provide a descriptive and comprehensive overview of the currently utilized PI documentation and classification tools contributing to increased evidence systematization. A systematic literature search was conducted in PubMed, Scopus, Web of Science and the Cumulative Index to Nursing and Allied Health Literature. Studies from 2008, after the release of the Basel Statements, were included if interventions were made by hospital or clinical pharmacists in a global hospital setting. Publications quality assessment was accomplished using the Mixed Methods Appraisal Tool. A total of 26 studies were included. Three studies did not refer to the documentation/classification method, 10 used an in-house developed documentation/classification method, seven used externally developed documentation/classification tools and six described method validation or translation. Evidence confirmed that most documentation/classification systems are designed in-house, but external development and validation of PI systems to be used in hospital practice is gradually increasing. Reports on validated PI documentation/classification tools that are being used in hospital clinical practice are limited, including in countries with advanced hospital pharmacy practice. Needs and gaps in practice were identified. Further research should be conducted to understand why using validated documentation/classification methods is not a disseminated practice, knowing patients' and organizational advantages.

Impact of Clinical Pharmacists-driven Bundled Activities from Admission to Discharge on 90-day Hospital Readmissions and Emergency Department Visits

Objectives

Patient-centered clinical pharmacists' activities play a major role in improving clinical outcomes by optimizing the efficacy of drug therapies and minimizing associated toxicities during hospitalization, at the transition of care, and upon discharge. We aimed to compare the impact of comprehensive versus partial clinical pharmacists-driven bundled of care services on the rate of 90-day hospital readmissions and emergency department (ED) visits.

Methods

This retrospective study included all admitted patients who received a comprehensive or partial bundle of clinical pharmacy services (medication history, interventions, counseling, and discharge prescription review) from 1 January 2021 to 30 June 2021 at Sultan Qaboos University Hospital. The comprehensive bundle of care included the four services, while the partial bundle of care included one, two, or three services only. Analyses were performed using univariate and multivariate statistical techniques.

Results

The study included 430 patients with a mean age of 56.021.0 years, and 43.7% (n = 188) were male. Of the patients, 12.1% (n = 52) received a comprehensive bundle of care. Compared with the partial bundle of care group, the comprehensive bundle of care group had significantly more patients with diabetes (65.4% vs. 42.9%; p =0.002), % 3 comorbidities (50.0% vs. 29.4%; p =0.003), and polypharmacy (% 5 medications) (73.1% vs. 46.0%; p < 0.001). The comprehensive bundle of care group was significantly associated with a lower 90-day readmission rate (adjusted odds ratio (aOR) = 0.27, 95% CI: 0.90?"0.82; p =0.021) but not with ED visits (aOR = 0.57, 95% CI: 0.13?"2.57; p =0.461).

Conclusions

This study demonstrated a significant reduction in the 90-day readmission rate for patients on a comprehensive bundle of care but not ED visits. These findings emphasize the importance of the comprehensive services provided by clinical pharmacists on the healthcare resources use and clinical outcomes.
