Understanding Principles of High Reliability Organizations Through the Eyes of VIONE, A Clinical Program to Improve Patient Safety by Deprescribing Potentially Inappropriate Medications and Reducing Polypharmacy

The calculations reported in Table 3 and Figure 4 are conservative and include only chronic outpatient prescriptions and do not account for medications deprescribed in inpatient units, nursing home, community living centers, or domiciliary populations. Data tracked separately from inpatient and community living center patient populations indicated an additional 25,536 deprescribed medications, across 28 VA facilities, impacting 7,076 veterans with an average 2.15 medications deprescribed per veteran. The additional achieved cost avoidance was $370,272 (based on $14.50 average cost per prescription). Medications restarted within 30 days of deprescribing are not included in these calculations.

The cost avoidance calculation further excludes the effects of VIONE implementation on many other types of interventions. These interventions include, but are not limited to, changing from aggressive care to end of life, comfort care when strongly indicated; reduced emergency department visits or invasive diagnostic and therapeutic approaches, when not indicated; medical supplies, antimicrobial preparations; labor costs related to packaging, mailing, and administering prescriptions; reduced/prevented clinical waste; reduced decompensation of systemic illnesses and subsequent health care needs precipitated by iatrogenic disturbances and prolonged convalescence; and overall changes to prescribing practices through purposeful and targeted interactions with colleagues across various disciplines and various hierarchical levels.

Discussion

The VIONE clinical program exemplifies the translation of HRO principles into health care system practices. VIONE offers a systematic approach to improve medication management with an emphasis on deprescribing nonessential medications across various health care settings, facilitating VHA efforts toward zero harm. It demonstrates close alignment with the key building blocks of an HRO. Effective VIONE incorporation into an organizational culture reflects leadership commitment to safety and reliability in their vision and actions. By empowering staff to proactively reduce inappropriate medications and thereby prevent patient harm, VIONE contributes to enhancing an enterprise-wide culture of safety, with fewer errors and greater reliability. As a standardized decision support tool for the ongoing practice of assessment and planned cessation of potentially inappropriate medications, VIONE illustrates how continuous process improvement can be a part of staff-engaged, veteran-centered, highly reliable care. The standardization of the VIONE tool promotes achievement and sustainment of desired HRO principles and practices within health care delivery systems.

Conclusions

The VIONE program was launched not as a cost savings or research program but as a practical, real-time bedside or ambulatory care intervention to improve patient safety. Its value is reflected in the overwhelming response from scholarly and well-engaged colleagues expressing serious interests in expanding collaborations and tailoring efforts to add more depth and breadth to VIONE related efforts.
