In a commuter city with frequent urgent care use and multiple referral handoffs, diagnostic problems can hide in plain sight. For example, a patient may:
- Go to urgent care for symptoms and receive initial imaging or labs.
- Be told to “follow up with primary care” or “recheck in X weeks.”
- Learn later—sometimes after another visit—that an abnormal result wasn’t acted on promptly.
- Experience worsening symptoms while waiting for referrals, authorizations, or scheduling.
In California medical negligence cases, timing is not a footnote. The key question is whether clinicians used a reasonable diagnostic process based on what they knew at the moment—and whether the delay contributed to harm.
