At many hospitals, medication history falls to whichever nurse is closest, wedged between dozens of other tasks.
At Cook Children’s, the work is treated as a specialty with a dedicated team of pharmacy technicians capturing 98% of medication histories at admission.
Alice Yeh, clinical pharmacy coordinator for Transitions of Care and the Emergency Department, calls that number the foundation of everything else.
“You’re giving the provider a cleaner list, which saves them time,” she said. “They’re ordering faster, and patients get the meds quicker because those orders hit our queue earlier.”
And the hospital sees fewer errors that lead to readmissions and longer stays.
To show the difference, Yeh ran an audit. She compared 100 medication histories her team completed with 100 it didn’t.
“You could see significantly more gaps where we’re not involved,” she said. “Missing frequencies, doses, strengths. In pediatric care, those gaps can be a big deal.”
Super techs
Cook Children’s clinical pharmacy technicians capture medication histories on inpatient floors, in the emergency department, and in the perioperative area. They coordinate discharges with the hospital’s Meds to Beds program, chase down missing doses, and triage questions from nurses before those questions reach a pharmacist. During codes and med alerts, they stand next to the pharmacist and draw up medications.
They notice when a dose, a drug, or a frequency looks off and flag it for the pharmacist.
“It does require a higher degree of knowledge of these disease states, of these drugs,” Yeh said.
Yeh points to a girl who arrived mid-seizure. The chart didn’t explain why, but a technician taking her history noticed she was on seizure medication with no rescue drug listed. So the technician asked additional clarifying questions and discovered the girl had run out of maintenance medications days earlier. That was why she seized and ended up in the emergency department.
Those catches often come from a conversation, not a chart. The technicians are skilled at talking with families and pick up what the notes leave out.
“When we take medication histories, we sometimes find patients haven’t been taking their medications at all,” said Mary Hernandez, clinical pharmacy technician supervisor. “Other times, their symptoms are side effects from taking a medication incorrectly.”
Training up techs
That kind of judgment is hard to hire, so the hospital grows it through a career ladder program:
- Tech 1: Preps oral doses and prepares non-sterile compounds
- Tech 2: Earns IV certification and prepares sterile compounds in a 797-compliant IV room
- Clinical tech: Support pharmacists in direct patient care and clinical decision-making
Each step adds new skills, so the expertise builds over time.
The ladder solves another problem, too. While turnover is common in pharmacy, Cook Children’s retains its technicians for years.
“Our techs have hung out for 10, 15, some people over 20 years in this role, because they find it fulfilling,” Yeh said. “If they leave us, typically they get promoted out to something else within the organization, because they’re so awesome.”
Because each promotion depends on an open, budgeted role, techs build experience while they wait. By the time someone becomes a clinical pharmacy technician, the skill is already there.
Freeing up pharmacists
A clean history doesn’t only protect the patient. It also gives the pharmacist and provider a list they can trust, so orders move faster.
In a code, the technician becomes a second set of hands. Yeh experienced that firsthand as an ED pharmacist.
“I’m in a code drawing up all my meds, I’ve blown through all the epi in my cart, and my tech already has me covered — they know it’s a head trauma, they’ve got my epi, they’re running to me with my hypertonic saline,” she said. “That independence and coordination makes a really big difference in these critical responses.”
Yeh calls them “pharmacist extenders.” They work to the top of their license so pharmacists can focus on what only they can do.
Holding the standard
When pharmacists noticed some drift in how medication histories were being documented, Hernandez built a live annual competency. She completes evaluations and scores each technician using scripted patient scenarios.
“You can’t just turn something on and let it run without checking to see how it’s going,” Yeh said.
The program is more than a decade old. It grew slowly, proving its value before earning more staff. Winning over nurses took the longest.
“At the very beginning, a huge challenge was just getting in there and getting known,” Hernandez said. “The nurses were used to getting the medication histories themselves. We did get some pushback. It was about building that relationship and letting them know we’re here to help.”
The payoff shows up in the numbers Yeh tracks — and in the ones she never has to. A history taken right the first time is a problem that never reaches the bedside.
