The Johnston Brief
When someone gets sick or hurt and it can't wait for a regular appointment but isn't life-threatening, urgent care is usually the right call. Johnston itself leans on nearby metro clinics for true walk-in care, so here's where the closest ones are, plus the plain rules for choosing between urgent care, the emergency room, and calling 911.
Johnston's in-town clinics are mostly appointment-based family medicine, so for a walk-in you'll usually head just outside town. The nearest dedicated walk-in urgent care is MercyOne Clive Urgent Care (1601 NW 114th St, Clive); the UnityPoint clinic on Merle Hay Road in Des Moines also offers walk-in care. Use urgent care for non-emergencies like minor injuries and illnesses. For chest pain, trouble breathing, stroke signs, or any life-threatening emergency, call 911 or go to the nearest ER.
The quick rule of thumb:
When in doubt about a true emergency, don't wait, call 911.
Because Johnston's own clinics are mainly appointment-based, the closest true walk-in urgent care options sit just over the city line:
In Johnston itself, UnityPoint Clinic Family Medicine - Johnston and The Iowa Clinic - Johnston handle primary care, mostly by appointment (they may accommodate same-day requests). Hours, wait times, and whether you can hold a spot online vary by clinic and can change, so check the clinic's own site or call before you go.
A few things that make the visit smoother: bring a photo ID and your insurance card, know the patient's current medications and allergies, and call ahead or check online for wait times. Many urgent cares let you check in or reserve a time online, which can cut the wait. If it's after hours and not urgent, your regular clinic's nurse line or a virtual visit (such as UnityPoint's or MercyOne's video urgent care) may be enough.

Go to the ER, or call 911, for anything life-threatening or serious: chest pain, trouble breathing, stroke signs, severe bleeding, head injuries, or major trauma. Use urgent care for non-emergencies like minor injuries, infections, and illnesses that can't wait for your regular doctor.
No. Johnston does not have its own hospital ER; the nearest full emergency rooms are in the greater Des Moines metro, including MercyOne Des Moines, UnityPoint Health - Iowa Methodist, and MercyOne West Lakes in West Des Moines. For a life-threatening emergency, call 911; responders will take the patient to the appropriate ER.
