Abstract:

Background

The Ross procedure is a technically complex operation to address the pathology of the aortic valve. Prior attempts at widespread implementation have been plagued with variations in effectiveness. We report our initial programmatic outcomes using dissemination and implementation (D&I) science frameworks, with an aim to define both programmatic efficacy and effectiveness. The study design was a single center, explanatory sequential mixed methods evaluation of a Ross surgery program from June 2020 to April 2023. Quantitative measures for baseline patient characteristics and postoperative outcomes were summarized. Qualitative measures were obtained using semi-structured interviews and characterized using implementation science frameworks.

Results

A total of 71 patients underwent the Ross procedure at a single academic center. Mean age was 40 years (± 13). There were no perioperative deaths or valve-related reinterventions (0%). During the follow-up period, 2 (2.8%) patients required re-operation and 2 (2.8%) required balloon dilation of the pulmonary homograft. Qualitative measures noted communication and prospective self-audit facilitated measures of effectiveness, as dichotomy within expected vs. observed outcomes led to program modifications. Collaboration across hospital systems promoted adoption and implementation, which led to the incorporation of the Ross procedure into accepted organizational practice.

Conclusions

In this formative evaluation, limited-efficacy outcomes demonstrated similar programmatic success to data from other established centers. With the prerequisite center volume and case selection, the Ross procedure is a safe and efficacious treatment for aortic valvular disease. Implementation science can be used both in real-time and retrospectively to guide organizational efforts to improve outcomes and to improve the translation of results across centers.

Abstract:

Introduction

Falls in nursing homes are a major cause for decreases in residents’ quality of life and overall health. This study aims to reduce resident falls by implementing the LOCK Falls Programme, an evidence-based quality improvement intervention. The LOCK Falls Programme involves the entire front-line care team in (1) focusing on evidence of positive change, (2) collecting data through systematic observation and (3) facilitating communication and coordination of care through the practice of front-line staff huddles.

Methods and analysis

The study protocol describes a mixed-methods, 4-year hybrid (type 2) effectiveness-implementation study in State Veterans Homes in the USA. The study uses a pragmatic stepped-wedge randomised trial design and employs relational coordination theory and the Reach, Effectiveness, Adoption, Implementation and Maintenance framework to guide implementation and evaluation. A total of eight State Veterans Homes will participate and data will be collected over an 18-month period. Administrative data inclusive of all clinical assessments and Minimum Data Set assessments for Veterans with a State Veterans Home admission or stay during the study period will be collected (8480 residents total). The primary outcome is a resident having any fall. The primary analysis will be a partial intention-to-treat analysis using the rate of participants experiencing any fall. A staff survey (n=1200) and qualitative interviews with residents (n=80) and staff (n=400) will also be conducted. This research seeks to systematically address known barriers to nursing home quality improvement efforts associated with reducing falls.
