This case study aimed to gain an understanding of the implementation and usage of a telehealth program during the COVID-19 pandemic at a rural healthcare facility. An action research methodology, utilizing cycles of planning, implementation, review and adaptation was adopted to improve use of telehealth as COVID-19 cases continued to increase. Data was collected from literature review, examination of existing documents, review of gap and SWOT analysis, and examination of staffing plans. This helped in ensuring that adequate resources were in place to start and continue usage of telehealth. Additionally, review of the entire process was conducted as the program advanced through various phases of implementation. By conducting rigorous analysis and reflection, these data informed cycles of improvement in the telehealth program. Challenges surrounding the continuation and usage of telehealth have also been described. Because there is a paucity of research on the use of telehealth programs in rural healthcare facilities, especially during the pandemic, this study can provide practical tips to leaders and healthcare managers.
