User-Centric Design: The Key to Health IT Innovation
By Kali Durgampudi, chief technology, innovation officer, Greenway Health.
Like so many industries in today’s Third Industrial Revolution, the pace of innovation in healthcare today is fast and ever-changing. New technologies – like artificial intelligence (AI), machine learning, big data, the Internet of Things (IoT) and voice recognition – are at the heart of applications and tools that are becoming demanded by patients and more ingrained in clinicians’ daily workflows.
For vendors developing new solutions based on these technologies, it appears they find themselves in a ‘race,’ striving to be first-to-market in order to establish their competitive edge. But being on the bleeding edge of innovation isn’t always easy. The healthcare industry has not been immune to this rapid quest for first-mover advantage. Often when this occurs, these new solutions sacrifice the quality and functionality required to deliver on promised improvements.
Think about the initial introduction of the electronic health record (EHR). Billed as a way to make practices and physicians more efficient, many early EHR solutions had the opposite effect – creating a significant learning curve and adding to physicians’ workloads overall. While EHRs may have made great strides toward digitizing medical records, taking paper and manual processes out of the equation, they often created new problems that placed different burdens on practices, providers and patients. In fact, in the early days, physicians reported spending more than half of their workday – an average of six hours – using the EHR, plus another 86 minutes after hours.
But EHRs are not the only healthcare technology solution attributing to this challenge – it transcends innovation across the entire health IT sector. As an industry, we must take a step back and slowdown to ensure all new technology can deliver meaningful change to practices, providers and patients.
How to Design New Healthcare Technology with the End-User in Mind
A key to ensuring healthcare technology delivers true benefits is considering how it will fit into day-to-day operations of the end-user – whether that be a patient, a nurse, a surgeon or a billing manager. Before introducing any new technology to the market, make sure your first intention is to get it right.
To do that, engineering teams must employ “user-centered design,” a concept that emerged in the mid-1980s. This approach, defined by the International Standards Organization, “aims to make systems usable and useful by focusing on the users, their needs and requirements, and by applying human factors/ergonomics, usability knowledge and techniques.” The goal ultimately is to enhance effectiveness and efficiency, improve human well-being, user satisfaction, accessibility and sustainability, and to counteract possible adverse effects of use on human health, safety and performance.
User-centered design in healthcare could entail shadowing a nurse to observe his workflow when triaging patients, following a surgeon to see how she develops post-op papers, or interviewing patients to understand how they obtain healthcare information in their daily lives.
With that experience, you can then ascertain what capabilities would make users’ lives easier or more effective. From there, determine if there’s a way to improve an existing product on the market to fulfill needs, or whether a completely new platform is required.
