Financial impact of medication reviews by clinical pharmacists to reduce in-hospital adverse drug events: a return-on-investment analysis

BACKGROUND

Adverse drug events contribute to rising health care costs. Clinical pharmacists can reduce their risks by identifying and solving drug-related problems (DRPs) through medication review.

AIM

To develop an economic model to determine whether medication reviews performed by clinical pharmacists could lead to a reduction in health care costs associated with the prevention of potential adverse drug events.

METHOD

Two pharmacists performed medication reviews during ward rounds in an internal medicine setting over one year. Avoided costs were estimated by monetizing five categories of DRPs (improper drug selection, drug interactions, untreated indications, inadequate dosages, and drug use without an indication). An expert panel assessed potential adverse drug events and their probabilities of occurrence for 20 randomly selected DRPs in each category. The costs of adverse drug events were extracted from internal hospital financial data. A partial economic study from a hospital perspective then estimated the annual costs avoided by resolving DRPs identified by 3 part-time clinical pharmacists (0.9 full-time equivalent) from 2019 to 2020. The return on investment (ROI) of medication review was calculated.

RESULTS

The estimated annual avoided costs associated with the potential adverse drug events induced by 676 DRPs detected was € 304,170. The cost of a 0.9 full-time equivalent clinical pharmacist was € 112,408. Extrapolated to 1 full-time equivalent, the annual net savings was € 213,069 or an ROI of 1-1.71. Sensitivity analyses showed that the economic model was robust.

CONCLUSION

This economic model revealed the positive financial impact and favorable return on investment of a medication review intervention performed by clinical pharmacists. These findings should encourage the future deployment of a pharmacist-led adverse drug events prevention program.

Improving Inpatient Medication Dispensing with an Automated System

Introduction

Medication inventory management and error prevention are complex issues. Single interventions are insufficient to make improvement across the spectrum. A uniform system for dispensing and distributing medications can help reduce the risk of medication errors, improve efficiency, and minimize waste. This quality improvement project aims to: 1) decrease - the time from ordering medication to administration, including delay incidents, by > 70%; and 2) decrease the inpatient monthly total medication consumption by > 20% and ward medication stock items by > 70%, including decreasing returned items and loss from in-house expired medications by > 70%.

Methods

A Six-Sigma approach was applied to eliminate deficiencies throughout the medication management process. Failure mode effect analysis and staff surveys were used to evaluate implementation of automated dispensing cabinet (ADCs) and reengineered workflows for expensive, misused, and restricted medications.

Results

After the new processes were implemented, the turnaround time from ordering medication to administration was reduced by 83%, with zero delay incidents reported. Most nurses (64%) and pharmacists (67%) stated that implementation of ADCs increased their productivity by more than 40%. Monthly medication consumption was reduced by 24%, with an estimated annual saving of $4,100,000 USD. The number of returned items per month was reduced by 72%, and the estimated annual savings from loss of in-house expired medications was $750,000 USD.

Conclusions

This quality improvement project positively impacted stock control while reducing costs and turnaround time for inpatient medication dispensing. Medication delay incidents were reduced, and staff satisfaction levels were positive. Next steps are to reengineer narcotic, anesthesia, and refrigerated products' management.

Implementation of the Automated Medication Dispensing System-Early Lessons From Eswatini

Objectives: This article describes the implementation of an automated medication dispensing system (AMDS) in Eswatini to increase medication access and presents the early lessons from this implementation. Methods: The AMDS was installed at four health facilities across two regions through collaborative stakeholder engagement. Healthcare workers were trained, and clients who met the inclusion criteria accessed their medications from the system. Each step of the implementation was documented and summarised in this article. Results: Early lessons suggest that implementation of the AMDS is acceptable and feasible to clients and healthcare workers and that phased introduction of medication classes, commencing with antiretroviral therapy (ART) and incorporating other medications in later phases is feasible. Additionally, improved client-centred messaging and communication, consistent power supply and internet network connectivity, and scheduling medication pickup with other services increase AMDS system utilisation. Conclusion: Eswatini has many clients living with HIV and non-communicable diseases (NCDs). Easy, convenient, quick, non-stigmatising and client-centred access to ART and medication for NCDs is critical in addressing retention in care and achieving optimal treatment outcomes.

An evaluation of automated dispensing cabinets and inventory robots for centralised distribution of medication in an Australian hospital

Objective In Australian hospitals, a central distribution system is often utilised to supply medication to clinical areas. This study investigated the impact of automated dispensing cabinets (ADCs) and inventory robots in medication distribution within an Australian hospital. Methods A prospective observational study of pharmacy technician medication supply to clinical areas was conducted over a 2-week period pre- and post-implementation of ADCs and inventory robots. Information was collected on the time taken to perform all tasks required to provide a weekly medication supply service for medication other than drugs of addiction. Results There was no significant reduction of total duration for medication supply, pre-implementation mean 73.08min versus post-implementation 68.59min (P =0.567). An instance of automation downtime occurred during the post-implementation period for which manual downtime procedures were implemented. Without downtime, a significant reduction in overall time taken was observed, 74.25min versus 63.18min (P =0.019). Pre-restocking medication selection errors were reduced non-significantly after implementation of inventory robots, 11 (0.43%) versus 4 (0.21%) errors (P =0.090). Conclusions Implementation of ADCs and robots did not significantly reduce the total time to provide a weekly medication supply service when downtime occurred, although a significant reduction was observed when downtime did not occur. Pharmacy medication selection errors were non-significantly lower. What is known about the topic? Australian hospitals are increasingly implementing automated technology such as ADCs and inventory robotics in an attempt to improve efficiency and accuracy of medication supply; however, limited literature is available in an Australian setting. What does this paper add? This paper describes the impact of implementing ADCs in clinical areas (e.g. inpatient wards) and inventory robots in a main store pharmacy on the medication supply process. This paper highlights the benefit of improved efficiency and accuracy in selecting medication in pharmacy for distribution and identifies time to restock the ADCs is significantly increased. What are the implications for practitioners? Implementing ADCs and inventory robotics in Australian hospitals can provide benefits in efficiency and accuracy; however, robust downtime procedures are essential.
