Electronic MAR is a good idea executed poorly often enough that you'll meet care home managers who quietly suspect it's a bad idea. It isn't. But the path between "the system was installed" and "medication accuracy improved" has six predictable potholes.
Mistake 1: Pharmacy isn't aligned
The eMAR system gets bought. The pharmacy is informed afterwards. The pharmacy continues to supply paper MAR charts, in pharmacy template, with their own conventions. The home now has paper and digital in parallel for medication, the worst category to be parallel in. Fix: pharmacy alignment is the first phone call after the contract is signed, not the last.
Mistake 2: PRN protocols aren't built
PRN ("as needed") medications are where most medication errors hide. They need a protocol, who can give, in what circumstances, how to evidence the need, how to evidence the effect. If the eMAR is rolled out without PRN protocols built into it, carers either skip PRNs (under-medicating) or default to giving them (over-medicating). Fix: PRN protocols, per resident, before go-live.
Mistake 3: Witness rules aren't designed
Controlled drugs require a witness. So do some homes' policies for high-risk medications. eMAR systems can enforce this, but only if the rules are configured, and only if the witnessing carer is in the building. Fix: witness rules built and tested with the actual roster, including nights.
Mistake 4: Offline scenarios aren't handled
Wi-fi goes down. The eMAR doesn't load. The carer needs to give the medication anyway. What's the policy? Most homes haven't written one. Fix: a one-page offline policy, signed, drilled, printed on the medication room wall.
Mistake 5: Refusals aren't audited
Refusal is a clinical event. Multiple refusals in a row are a clinical pattern. Most paper MARs record refusals as a letter. Most eMARs do better, but only if someone reviews the pattern. Fix: weekly refusal review by the deputy, in the dashboard.
Mistake 6: Going live without the night team
Night teams are smaller, less senior on average, and historically less consulted. They administer fewer medications, but the ones they administer matter (PRN pain relief, hypnotics). Going live without dedicated night training is going live with the hardest team unsupported. Fix: dedicated night-shift go-live with manager presence for the first two nights.
The honest truth about eMAR
eMAR is a substantial change to a high-risk process. It rewards the homes that respect it as a clinical project, not an IT project. The systems are mature; the rollouts vary wildly. The variable isn't the software.
