Implementation of a Community Pharmacist-Led Testing Program for HIV, Hepatitis C and Syphilis in Canada
The APPROACH 2.0 study demonstrates that a pharmacist-led testing program for HIV, hepatitis C, and syphilis in Canadian community pharmacies successfully reached untested populations, confirmed active infections, and proved feasible for implementation, highlighting its potential to improve public health outcomes by reducing barriers to care.

Imagine the healthcare system as a giant, bustling city. For a long time, the only way to get a specific health check-up was to visit the "City Hall" of medicine: a doctor's office or a hospital clinic. These places are essential, but they can be crowded, hard to reach, and sometimes feel intimidating if you're worried about what the test might reveal. Because of this, many people who should get tested for hidden health issues simply never show up. They stay in the shadows, and the infections they might carry can spread without anyone knowing.
To fix this, scientists are exploring a new strategy: taking the "check-up station" out of City Hall and setting up pop-up booths in the places people already visit every day, like the local grocery store or the neighborhood pharmacy. This idea relies on a simple truth: if you make it easier, faster, and less scary to get tested, more people will do it. The goal isn't just to find sick people; it's to catch problems early, stop them from spreading, and make sure everyone feels safe enough to ask for help. This paper dives into a real-world experiment to see if turning regular pharmacists into health detectives works, and if people actually like the new, convenient way of getting tested.
The Pharmacy Detective Squad: A Real-World Test
In this study, a team of researchers across three Canadian provinces (Newfoundland and Labrador, Nova Scotia, and Alberta) decided to turn community pharmacies into secret health hubs. Their mission? To see if pharmacists could successfully run a testing program for three tricky infections: HIV, Hepatitis C, and Syphilis. Think of these infections as invisible invaders that can hide in the body for a long time. The researchers wanted to know if handing the "detective work" to pharmacists—who are usually the friendly experts you see when you pick up your cold medicine—could reach people who had never been tested before.
The Setup: Two Ways to Play
The researchers didn't just force one method on everyone. They offered participants a choice, like picking your own adventure.
- The "Instant Reveal" (Point-of-Care): You prick your finger, and within minutes, you get a result right there in the pharmacy. It's like getting a quick answer to a riddle immediately.
- The "Mystery Mail" (Dried Blood Spot): You prick your finger, put a drop of blood on a special card, and mail it to a super-lab. You have to wait a bit longer for the answer, but this method can test for all three infections at once.
Before the testing began, the pharmacists went through a rigorous training camp. They learned how to explain the tests, how to collect the tiny blood samples, and most importantly, how to deliver bad news with kindness and connect people to doctors who could help.
The Results: Catching the Unseen
Between late 2022 and early 2024, the program was a hit. A total of 399 people walked into these pharmacies to get tested. Here is what the numbers tell us:
- New Faces: The program was incredibly successful at reaching people who had never been tested before. About 35% of the HIV tests, 43% of the Hepatitis C tests, and a whopping 62% of the Syphilis tests were given to first-time testers.
- The "Why": Why did people choose the pharmacy? For 79% of the participants, getting results immediately was the most important thing. Some were so eager they said they wouldn't go anywhere else if the pharmacy wasn't open that day.
- The Findings: Out of all the tests, 25 people got a "reactive" (potential positive) result. After follow-up testing at standard labs, the team confirmed 4 active Hepatitis C infections and 2 active Syphilis infections. Interestingly, 5 out of these 6 people with confirmed infections were first-time testers. This proves the program found people who were flying under the radar.
The Speed Bumps (What Didn't Go Perfectly)
The study wasn't without its hiccups, and the researchers were honest about them.
- The Wait: While the instant tests were fast, the "Mystery Mail" blood cards took time. In some provinces, it took a median of 20 to 25 days to get the results back.
- The "Grey Zone": Sometimes the blood cards gave results that were "indeterminate" or in a "grey zone"—not clearly positive, not clearly negative. This happened with 9 syphilis tests. The lab had to do extra work to figure it out, which can be confusing for both the pharmacist and the patient.
- The Drop-off: Not everyone who tested positive followed through with the confirmatory testing. Out of the 25 people with reactive results, only 16 completed the final confirmatory tests. Some people dropped out, didn't show up, or chose to get tested elsewhere.
The Big Picture
The paper concludes that this pharmacist-led model is a feasible and effective way to find infections that might otherwise go unnoticed. It suggests that putting testing in pharmacies breaks down barriers for people who are afraid of hospitals, don't have a regular doctor, or just want a quick, private answer.
However, the authors are careful not to call this a "solved problem." They note that for this to work on a massive scale, the system needs to get better at handling the "grey zone" results and making sure people who test positive actually get the care they need. The study suggests that while the idea works, the logistics—like how fast results come back and how to keep people on the path to treatment—need more fine-tuning.
In short, the pharmacy is a promising new front line in the fight against these infections. It's a friendly, accessible place where people are willing to come forward, but the journey from a quick test to full treatment still needs some road repairs to make it smooth for everyone.
