Impact of Point-of-Care Testing on Emergency Department Throughput and Clinical Decision-Making: Experience from Two High-Complexity Centers
This retrospective study of two high-complexity hospitals in Bogotá demonstrates that while Point-of-Care Testing significantly improved diagnostic turnaround times and supported clinical decision-making, it did not reduce overall emergency department length of stay, which remained constrained by broader organizational and structural factors.

Imagine you are stuck in a massive traffic jam. The cars are moving, but they are crawling because every driver is waiting for a specific traffic light to turn green before they can even start their engines. Now, imagine if, instead of waiting for a distant traffic control tower to send a signal, every car had a tiny, super-fast sensor right on the dashboard that could instantly tell the driver, "Okay, the road ahead is clear, go!" This is the basic idea behind Point-of-Care Testing (POCT). In the world of medicine, specifically in the chaotic, high-speed environment of a hospital's Emergency Department (ED), time is the most valuable currency. Traditionally, when a doctor needs to know what's wrong with a patient, they send a blood sample to a giant, centralized laboratory. It's like sending a letter across town and waiting days for a reply. POCT flips the script: it lets doctors run those tests right at the patient's bedside, getting answers in minutes instead of hours. The big question scientists have been asking is: Does having these super-fast answers actually clear the traffic jam in the hospital, or do other bottlenecks keep the cars stuck?
This study, conducted by a team of researchers in Bogotá, Colombia, decided to put this theory to the test in two of the city's most advanced hospitals. They looked at the records of over 14,000 patients who were treated using these bedside tests between January and March 2026. Think of the Emergency Department as a busy airport terminal. The researchers wanted to see if using POCT helped planes (patients) get through security (diagnosis) faster and get to their gates (disposition) quicker.
The results were a mix of "mission accomplished" and "we still have some traffic to clear." First, the good news: The "dashboard sensors" worked exactly as advertised. In one hospital, it took an average of just 10.2 minutes from the moment a blood sample was taken to the moment the doctor had the result. In the other, it was 14.2 minutes. Compare that to the old way, where results might take 45 to 90 minutes, and you can see why this is a game-changer. It allowed doctors to make decisions much faster, especially for the vast majority of patients (over 90%) who fell into the moderate-risk categories (Triage III and IV). The study found that these faster results helped hospitals get patients to a "disposition"—meaning a decision to admit them to a room or send them home—in a median time of 143 and 162 minutes, respectively. Both numbers were well under the hospitals' goal of 240 minutes.
However, the story gets a little more complicated when you look at the total time a patient spent in the ER. You might think that if the test is done in 10 minutes, the whole visit should be super short. But the researchers found that the total time a patient stayed in the ER actually got longer as the months went on. In the first hospital, the median stay crept up from 227 minutes in January to 247 minutes in March. In the second, it went from 253 to 266 minutes.
Why did this happen if the tests were so fast? The paper suggests that the "traffic jam" wasn't caused by the speed of the test itself, but by what happened before and after the test. In one hospital, there was a noticeable delay between when a doctor ordered the test and when a nurse actually collected the blood sample. It was like having a fast car but getting stuck waiting for the driver to get in. The researchers also pointed out that even with a quick diagnosis, patients still had to wait for things outside the doctor's control, like an empty hospital bed to become available or the paperwork to be processed for discharge.
So, what's the bottom line? The study concludes that POCT is a fantastic tool that definitely speeds up the diagnosis part of the journey. It helps doctors figure out what's wrong much faster and supports better decision-making. But, it's not a magic wand that solves every problem in the Emergency Department. The overall time a patient spends in the hospital is still heavily influenced by the bigger picture: how many beds are open, how busy the hospital is, and how smooth the administrative processes are. The researchers suggest that while we should definitely keep using these fast bedside tests, we also need to fix the other parts of the system—like the pre-test delays and the bed availability—to truly clear the traffic jam and get patients moving efficiently.
