Globally, approximately 44,000 to 98,000 deaths annually are linked to medication errors. This is a staggering statistic that is being driven by the mounting pressures placed upon healthcare professionals, with little support provided. MedNurse is an emerging app developed to help nurses take further steps to prevent these numbers from rising, providing them with the information and support required to keep their patients safe. We spoke with Theary Ros below, Founder and CEO of MedNurse, as the pioneering app has been recognised in the Healthcare and Pharmaceutical Awards 2025.
“MedNurse exists to help every nurse make the right med decision no matter the pressure, no matter the shift.”
One of the most significant challenges in the healthcare sector, and nursing in particular, is the growing combination of information overload and poor accessibility. Nurses must maintain protocols, drug references, and new policies, all whilst managing patient care in real-time. The system does not currently support those under such pressure and, when something goes wrong, it is often wrongly blamed on “user error.”
This is a significant gap, and one that MedNurse is stepping up to fill. MedNurse was founded by Theary Ros, a former ER nurse who saw firsthand that even the most experienced clinicians struggle under pressure when the correct information is not available at the right moment. Too often, Theary witnessed medication errors occurring not because of carelessness but due to complexity, interruptions, unclear protocols, or a lack of accessible tools.
In response, Theary founded MedNurse, a platform designed to bridge the gap between knowledge and practice. Launched in 2023, this groundbreaking application combines clinical accuracy with real-world usability to provide nurses with instant access to interactive tools they can trust. From dosage calculators and clear, step-by-step medication guides to mixing instructions and real-world practice scenarios, MedNurse has been built to support and empower nurses, wherever they work.
At its heart, MedNurse is a community space built by nurses, for nurses. Driven by a mission to reduce medication errors and enhance patient safety in healthcare environments around the world, the application boasts a wide array of innovative features that include an expansive medication database; an accurate dosage calculator; a toolbox of educational materials and training; frequent safety alerts and reminders; reporting and analytics features to track errors; a customisable personal and professional profile; and a clean, intuitive, and easy-to-navigate profile.
“MedNurse is different because it was created from inside the shift, not outside of it,” Theary told us. “We built it based on real frustrations, missed moments, and the constant need nurses have for clear answers when time is short, and the stakes are high. It is not a system we expect nurses to adapt to; it is a tool that adapts to nurses. No login, no multi-click dashboards, no fluff. Just quick, safe guidance in the moment it is needed. Whether it is confirming how to mix a medication or checking what to give and when, MedNurse is built for use during real workflows, not just policy reviews.”
“Whether you are a student seeking confidence on your first med pass, a preceptor guiding new graduates, or a quality leader looking to implement safer workflows, we have designed MedNurse to meet you there.”
Today, MedNurse serves as more than a tool; it is a movement in nursing safety and support. The application has been designed with accessibility in mind, catering to individual nurses, educators, and entire hospital systems. Hospitals can license MedNurse for customised implementation, complete with branded dashboards, staff usage insights, and compliance-ready materials; nursing programmes can integrate its simulation tools and safety modules into their training; and independent nurses can access quick-reference tools for free at mednurse.com, with no downloads or sign-ins required.
This wide range of applications is made possible by the company’s core values of safety, clarity, simplicity, and respect for the realities of nursing work. Everything MedNurse does is built on the non-negotiable belief that medication safety should never be complicated. The company aims to provide nurses with tools that are fast, visual, and directly relevant to their real-life operations, each designed to answer one question: “Can a nurse use this mid-shift without stopping what they are doing or second-guessing themselves?”
“If the answer is no, we go back and fix it,” Theary stated. “If a tool is not easy to use in the middle of a busy shift, it does not belong on our platform. We listen to what nurses say they need. That feedback drives how we build, simplify, and prioritise. As a result, we have gained genuine trust across units and campuses. Nurses tell each other about MedNurse, not because we marketed to them but because it helped them when they needed it.”
In an industry full of apps that are either too technical or too removed from the bedside, remaining firmly rooted in what nurses actually experience daily has helped MedNurse to grow as a trusted name in patient safety. Designing with the input of nurses at every step of the way means that its content feels familiar, not forced – never aiming to replace nurses’ judgement but to provide unwavering support, education, and empowerment in a continually evolving landscape.
“We did not build MedNurse to be competitive; we built it to be useful. The trust we have earned came from delivering what nurses need.”
With this client-centric approach at its heart, MedNurse does not consider its most significant breakthrough to be a single feature, but the trust it has earned from nurses. When the application launched, it aimed to become something that nurses genuinely use and benefit from, rather than yet another app collecting dust on their phone’s home screen. Now, nurses print out MedNurse guides and tape them to med carts, keep Mednurse open on their phones during a shift, and even utilise its tools during codes – demonstrating precisely how popular its features have become.
One significant achievement came from a nurse working in a medical-surgical unit. The nurse was covering multiple patients and needed to quickly confirm the dilution and rate for a high-alert IV med. She referenced MedNurse to double check her assessment and later told the company that the app had helped her remain calm and confident in a moment that could have resulted in chaos. She said: “I did not have time to flip through a binder or call the pharmacy. I needed a clear answer fast.”
“That moment stuck with us,” Theary recalled. “Because it is not about having the most features; it is about delivering the proper support in the right moment. That kind of trust does not happen overnight. It comes from listening, simplifying, and designing with real workflows in mind. That is our proudest success: MedNurse has become a trusted tool for nurses when it counts most.”
Since its inception, MedNurse has been instrumental in empowering nurses to deliver care with skill, precision, and confidence. Tom, a Student Nurse, said of the app: “What I have come to appreciate most about the MedNurse app is the built in dosage calculator, which has proven invaluable when it comes to double-checking my calculations and assuring accurate medication administration.”
Jill, a Registered Nurse with a Bachelor of Science in Nursing, reported: “As a veteran nurse with years of experience in my field, I find the most comprehensive guide on safely and properly administering medication to be an invaluable resource for both novice and seasoned nurses alike.”
This feedback is invaluable to MedNurse, a company dedicated to utilising practical and thoughtful tools to transform not only how nurses work but also how patients experience care. “Adapting also means listening,” Theary explained. “Our growth is not based on trends, but on real-time feedback from the people who use the platform. We continually evolve based on what nurses tell us they need. That is how we stay grounded and relevant, even as the healthcare industry continues to evolve.”
In the spirit of evolution, MedNurse is working on a number of projects that continue to focus on real-time medical safety and ease of use. At present, the company is building a library of visual learning tools – including simple but effective graphics and workflows – that can be printed, shared in huddles, and kept on mobile phones for instant access during a shift.
MedNurse is particularly excited to reveal the upcoming expansion of its step-by-step medication safety guides and tools based on what nurses have specifically requested, including updated guides for high-alert medications, visual dosing references, and how-to instructions for complex scenarios such as insulin drips and IV pushes. Nurses should not have to second-guess if their work is right, and these quick references are crucial in closing that gap without adding pressure.
What’s more, MedNurse is also working with several hospital campuses to create customised dashboards for their educators and stroke teams. These dashboards allow them to track how the tools are being used, identify where more support is needed, and tailor in-services and workflows around real data. This allows MedNurse to expand beyond providing clients with the right tools, ensuring that they are being used in ways that matter.
The company is gearing up for another significant project, in the form of MedNurse Paediatrics. It recognises that paediatric medication administration comes with its own unique level of pressure, and as such is developing focused tools designed to support nurses in this area – starting with weight-based dosing cards and simplified calculation references.
“Behind the scenes,” Theary added, “we are also enhancing how MedNurse integrates with existing hospital training programmes and compliance goals – while still providing easy access for individual nurses who need a clear answer mid-shift. We are not chasing complexity; we are staying focused on the same mission: making it easier for nurses to safely administer the proper medication at the right time with confidence.”
In the longer-term, MedNurse envisions national and global expansion. The challenges nurses face are not unique to one hospital or region; they are shared by nurses around the world. Through its innovative applications and client-centric approach, MedNurse has the true potential to reach nurses everywhere to provide them with support, clarity, and tools they can trust in real-time – a platform truly deserving of the Excellence Award in Bedside Medical Safety 2025.
As word of the platform’s efficacy continues to spread, MedNurse has been humbled by the growing interest shown by healthcare investors. The company has not chased funding, instead attracting investors who can see the future of nursing care within what the company has built. Ultimately, its work demonstrates that clinically grounded, tech-enabled tools can reduce risk, save time, and enhance the experience of both patients and providers.
Since its inception, MedNurse has operated with an unwavering commitment to its sole mission of reducing med errors and making healthcare safer, without complexity. Its platform well-equips nurses for success; its TNK tool alone has supported hundreds of safe stroke activations, and its quick reference guides have been printed and laminated in nursing units across New York and beyond. For reshaping the landscape of healthcare, and serving the patients behind every decision, MedNurse has earned the rightful recognition as the USA’s Best Emerging Nursing and Medical Administration Solution 2025.
“We did not build MedNurse to win awards; we built it to save lives. But we are honoured that you see it too,” Theary concluded. “We do not measure success in downloads or data points. We measure it in every quiet moment where a nurse feels just a little more confident, a little more supported, and a little more seen.
“If you are reading this and wondering if MedNurse is for you, it is. Because if you care about patient safety, you are already part of our community.”
