Mistakes That Could Happen in Hospitals

A hospital stay brings a mix of hope, anxiety, and trust. You place your well-being, or that of a loved one, into the hands of a complex system staffed by dedicated professionals. But behind the curtain of care lies a startling reality: preventable medical errors are far more common than most people realize Mistakes That Could Happen in Hospitals.

The gravity of this issue is profound. “Nearly a quarter of seriously ill hospitalized adults had a delayed or missed diagnosis, with three-quarters of these errors contributing to harm, and diagnostic errors playing a role in about one in 15 hospital deaths,” according to UCSF research

While any patient is at risk, the consequences are especially devastating for the most vulnerable, such as newborns during childbirth. When a preventable mistake during delivery leads to a permanent condition, families often need guidance from a trusted medical malpractice lawyer in Lancaster who understands both the medical and legal complexities. Working with experienced counsel ensures parents can focus on their child’s care while getting support navigating the next steps, giving them clarity and confidence during an overwhelming time.

This guide is not about instilling fear. It’s about empowerment. We will provide you with a practical toolkit of simple questions to help you become an active, effective partner in your own healthcare, enhancing safety at every step.

The “Big Four”: Understanding the Most Common Hospital Errors

To be an effective advocate, it helps to know what you’re watching for. Most hospital errors fall into four main categories. Understanding them provides the context you need to ask the right questions.

  • Diagnostic Errors: These are missed, wrong, or delayed diagnoses. They prevent patients from getting the correct treatment in a timely manner. The issue often lies in the background processes. In fact, most errors (nearly 70 percent) occurred during the testing process—ordering, collecting, processing, obtaining results, or communicating results, as revealed by ECRI data analysis.
  • Medication Errors: This common error involves a patient receiving the wrong drug, an incorrect dose, or a medication intended for someone else. These mistakes can happen at the pharmacy, during data entry, or at the bedside.
  • Healthcare-Associated Infections (HAIs): These are infections a patient acquires while in a healthcare setting. They are often caused by antibiotic-resistant bacteria and can lead to serious complications. Proper hygiene is the single most effective prevention method.
  • Communication Failures: Critical information can get lost during shift changes, when a patient is transferred between departments, or when test results are not clearly conveyed to the right doctor. These gaps in communication can lead to serious adverse events, a fact underscored in WHO patient safety guidelines.

Your Patient Safety Toolkit: The Right Questions to Ask at the Right Time

Here is your practical, non-confrontational script. These questions are designed to open lines of communication and serve as simple safety checks throughout a hospital stay.

Upon Admission: Setting the Stage for Safety

The first few hours in a hospital are crucial for establishing clear communication and verifying essential information.

  • Question about Allergies:

“Can we double-check that my allergy to [medication/food] is clearly listed in my chart and on my wristband?” This simple verification ensures that one of the most critical pieces of safety information is correct and visible to everyone on your care team.

  • Question about the Primary Contact:

“Who is the lead doctor or hospitalist managing my care, and how can my family best get updates from them?” This establishes a clear point of contact, preventing confusion and ensuring that information comes from a single, accountable source.

  • Question about Hand Hygiene:

“I’m sure you do this a thousand times a day, but would you mind using the hand sanitizer before you start?” Phrased politely, this question reinforces infection prevention without coming across as an accusation. It’s a gentle reminder that keeps everyone safer.

During Your Stay: Staying Vigilant with Daily Care

Continuous engagement is key to preventing errors that occur during routine treatment and staff transitions.

  • Question Before Any New Medication:

“Could you tell me what this medication is for and confirm it’s for me before I take it?” Before accepting any pill or IV drip, this two-part question confirms both the purpose of the medication and, crucially, that it’s intended for the right patient.

  • Question about Tests and Procedures:

“Can you explain what this test is for and when we can expect the results? Who will share them with me?” This helps you understand the purpose of medical actions and creates a clear expectation for follow-up, reducing the risk of critical diagnostic information getting lost.

  • Question During Shift Changes:

“Since you’re just starting your shift, could we quickly review my main issues and the plan for today?” A brief recap with the incoming nurse or doctor can catch potential gaps in communication that may have occurred during the patient handoff.

Before Discharge: Ensuring a Safe Transition Home

Mistakes and confusion don’t just happen inside the hospital. A safe discharge is critical to preventing post-hospital complications.

  • Question about Instructions:

“Can we go over my discharge paperwork together? I want to make sure I understand all the instructions, warning signs, and who to call if I have a problem.” Never leave with a stack of papers you haven’t reviewed. This ensures you understand your care plan, know what symptoms warrant a call, and have the right emergency contacts.

  • Question about Medications:

“Can we confirm which medications I should stop taking and which I should continue at home, including any new prescriptions?” Medication reconciliation is vital. This question prevents dangerous mix-ups and adverse drug events once you are back home.

  • Question about Follow-Up:

“Who is responsible for sending my hospital records and test results to my primary care doctor?” This guarantees continuity of care. It closes the loop between your hospital stay and your long-term health management with outpatient providers.

How to Be an Advocate, Not an Adversary

Many people fear that asking questions will label them as “difficult.” The key is in the approach. Your goal is to be a partner in care, not an opponent.

  • Use “We” and “Us”: Frame your questions collaboratively. Saying, “Can we review the plan?” fosters a team approach. It positions you as part of the solution rather than someone looking for problems.
  • Keep a Notebook: Jotting down questions, the names of doctors and nurses, and their answers is a powerful tool. It shows you are organized and attentive, not aggressive. It also helps you remember details during a stressful time.
  • Pick the Right Time: Avoid asking complex questions when a nurse is clearly rushing during medication rounds. Instead, say, “I have a few questions when you have a moment. When would be a good time for a brief chat?”
  • Escalate Calmly: If you feel your concerns are not being addressed, don’t get angry. Calmly and respectfully ask to speak with the charge nurse, a patient advocate, or the attending physician.

What to Do If You Suspect an Error Has Occurred

If you believe a mistake has happened, it’s essential to act quickly, calmly, and methodically.

  1. Speak Up Immediately: Voice your concerns to the nurse or doctor on duty as soon as you notice something is wrong. State the facts clearly and calmly. For example, “I was supposed to get my blood pressure medication an hour ago, but I haven’t received it yet.”
  2. Document Everything: Write down the details immediately. Note what happened, the exact date and time, who was involved (names and titles), and the response you received. Specificity is your greatest asset.
  3. Request Your Medical Records: You have a legal right to your medical records. Submit a formal request to the hospital’s medical records department for a complete copy. Do this before and after discharge to ensure you have the most complete information available.

Conclusion

Being in the hospital can make you feel powerless, but you have more agency than you think. An informed, engaged patient—or a vigilant family member—is one of the most effective safety measures in any healthcare setting.

Asking simple, proactive questions is not a sign of distrust; it is the foundation of a true partnership in care. These questions help hard-working medical professionals do their jobs safely and effectively. By using this guide, you can take control of your healthcare journey, protect yourself and your loved ones, and ensure the best possible outcome.
