Medication dispensing errors and prevention: how smart automation can help 

featured image

Medication errors claim thousands of lives and affect over seven million people across the United States each year. About one-third of these errors occur when medications are dispensed to patients or loved ones.

Read on to learn how automating the medication dispensing process can help minimize the risk of medication errors, offering relief for overburdened caregivers and healthcare professionals.

What are the most common medication dispensing errors?

Incorrect medication or dose

Medication errors can occur when patients are administered the wrong type of medication or an incorrect dose of the correct medication (an overdose or an underdose). Such errors can have severe outcomes; in some instances, it can even be fatal.1 

These consequences can extend beyond the patient – a few years ago, RaDonda, a nurse in Tennessee, administered the wrong medication to a 72-year-old patient who ultimately suffered brain damage. RaDonda was charged with reckless homicide and felony abuse of an impaired adult, and subsequently convicted of negligent homicide.10 

Incorrect timing 

When meds are not taken at the right time, they may be less effective. Some medications work best when taken with food, while others may need to be taken on an empty stomach. Research shows that certain blood pressure medications are most effective when taken at bedtime as older individuals may experience high blood pressure while asleep, facing higher risks of heart attacks and stroke than younger patients.11 Given this, it’s crucial to administer medications at the right times in order to optimize a patient’s health outcomes. 

Why do medication dispensing errors happen?

Patient errors

According to the World Health Organization, 50% of patients do not take their meds as prescribed, leading to countless avoidable deaths and hospitalizations.12,13 Taking the right meds at the right time can be challenging for people managing more than one chronic condition, especially when multiple physicians and different pharmacies are involved. Patients battling more than one chronic illness may also experience memory issues, vision impairment, or other problems that make it all the more difficult to take their meds as prescribed.1,4 

Caregiver errors

A caregiver is anyone who takes care of a person with an illness, disability, or special needs. Healthcare professionals with caregiving responsibilities, like nurses, are often pulled in many directions at work. Similarly, caregivers who are family members or friends face distractions and high levels of stress as they attempt to balance work and caring for their loved ones. Distractions have been shown to increase the potential for errors when administering medications to patients or loved ones, including giving someone their meds at the wrong time, skipping a dose, or dispensing the wrong dose.6,7

Pharmacist errors

Pharmacists can indirectly contribute to medication dispensing errors by failing to carefully review prescriptions before administering them. A pharmacy’s prescription management software may even fail to flag inappropriate dosages or meds, further contributing to potential pharmacy-related medication dispensing errors.5,8

Payer errors

While payers are not directly responsible for medication dispensing errors, they can encourage providers and pharmacies to minimize medication errors. For example, they may enforce the fact that relying solely on self-reporting from patients on medication adherence may be outdated and inaccurate.9 They can also help subsidize medication dispensers and remote monitoring devices to help track patient compliance and help reduce errors. 

Medication dispensing errors & prevention: how smart automatic dispensers can help 

Automating the medication dispensing process can help deliver the right meds to the right patient at the right time. 

Consider Hero, a medication management service that makes it simple to take the right meds as prescribed for people managing multiple medications. Hero includes a smart dispenser that stores up to a 90-day supply of 10 different meds, which reduces the need for frequent refills and helps lower the number of manual errors. The connected app allows you to set your dispensing schedule, so the dispenser can let you know when it’s time for a dose and dispense the meds you need at the push of a button. 

Hero automatically tracks what pills were taken and when, so patients can share accurate adherence data with their providers and pharmacies. This type of system can also help busy caregivers keep track of dosage times, and can even notify them if their loved one missed a dose or took a medication late. 

What’s more, Hero takes care of refills with its complementary prescription refill and delivery service. This way, medications are automatically refilled and delivered to patients’ doorsteps every month, benefiting everyone involved. 

Smart medication solutions like Hero can help prevent common medication dispensing errors, improve patient safety, and help patients get the right medication when they need it.
