The Benefits and Challenges of Telemedicine as Hospital Queues Move to Mobile Screens

Imagine a mother in a remote area having to travel for hours just for a blood sugar check-up, or a post-operative patient forced to sit for ages in a hospital waiting room for a five-minute consultation with a doctor. Such scenarios are a near-universal complaint in healthcare, and it is precisely here that telemedicine—technology-based remote health services—has become an increasingly difficult solution to ignore. Since the COVID-19 pandemic, the use of telemedicine has surged dramatically across the globe. The question now is no longer whether telemedicine is useful, but how effective, cost-efficient, and ready our health systems are to adopt it comprehensively. Insights from various international studies help answer this. In a review published in Sensors International (2021), Haleem and colleagues explain that telemedicine is not merely a simple video consultation. The technology encompasses remote patient monitoring, electronic medical records, digital prescriptions, and even consultations between specialists in different cities. For patients in areas with limited healthcare access, telemedicine allows them to receive medical attention without travelling long distances, taking time off work, or risking infection in crowded waiting rooms. These benefits are also tangible in post-operative care. A randomised clinical trial by Yao, Fleshner, and Zaghiyan (2023) on 46 colorectal surgery patients in the United States found that satisfaction levels among those who had post-operative check-ups via telemedicine were comparable to those who visited the clinic in person. The virtual visits also tended to be shorter without increasing the risk of readmission. For routine check-ups that do not require direct physical intervention, a mobile screen can genuinely replace the examination table. One of the main attractions of telemedicine is the promise of cost efficiency, though the reality is not always straightforward. In a systematic review of 22 studies on the cost-effectiveness of telemedicine for diabetes management, Ofir Ben-Assuli (2022) found that a majority reported telemedicine—whether via telephone, blood glucose monitoring apps, or teleophthalmology for diabetic retinopathy screening—was cost-effective compared to conventional care. However, the review also noted that the calculation methods varied widely and most studies did not thoroughly examine factors that could alter the results. While telemedicine has the potential to save healthcare costs in the long run, this benefit depends heavily on the type of disease, patient population, and service model applied; it is not an automatic guarantee for all conditions. Despite these positive findings, the widespread implementation of telemedicine is far from straightforward. Kruse and team (2020), reviewing 48 articles on health policy and telemedicine, identified several major barriers: initial costs not covered by reimbursement schemes, concerns over patient data privacy and security, a technology skills gap between different age and economic groups, and varying licensing regulations for medical professionals across regions. Conversely, the biggest driving factors were simple: improved access to care, patient convenience, and the increasing ownership of smartphones, even in developing countries. These findings serve as a reminder that telemedicine is not a magic bullet that can be applied instantly without careful planning. It requires clear policies on data security, incentives for healthcare workers, and digital literacy education for patients, particularly the elderly who are often less familiar with technology. Digitalisation in healthcare is not just about bridging geographical distances. Research by Astiena and colleagues (2022) at a public hospital in West Sumatra, Indonesia, demonstrated that applying digitalisation based on lean management principles—eliminating non-value-added steps in the service process—drastically reduced outpatient waiting times from an average of 336 minutes to just 39 minutes, a drop of around 88 percent. The method was simple yet impactful: a digital appointment scheduling system integrated with doctors’ practice schedules, so patients no longer needed to arrive at dawn and queue for hours just to get a queue number. This finding completes the broader picture of healthcare digitalisation: it is not only about bridging geographical distances through video consultations, but also about streamlining service flows within the hospital itself. For policymakers, these findings signal that investment in telemedicine and hospital digitalisation is not a passing trend but a strategic step that must be supported by adequate regulations, from fair financing schemes and patient data security guarantees to digital literacy training for health workers and the public. For hospitals and community health centres, it shows that significant change does not always require sophisticated, expensive technology; a simple digital appointment system can significantly cut waiting times. And for us as patients, telemedicine is no longer a distant future concept but a service that is already at our fingertips, waiting to be used wisely.
