How to Sue for Medical Malpractice in Arizona

I'm Gil Hacohen, a Phoenix attorney and founder of Lawyers For Less. When someone is injured or facing a legal problem they did not choose, they may find themselves dealing with serious consequences, mounting expenses, lost income, and an insurance company or opposing party determined to minimize its responsibility. I believe people deserve an attorney who will take the time to understand their situation, investigate what actually happened, and challenge the other side's version of events when the evidence tells a different story. My job is to protect my clients' interests, hold responsible parties accountable, and pursue the outcome they deserve.

What is Medical Malpractice in Arizona?
Medical malpractice occurs when a healthcare professional provides substandard care, resulting in harm to a patient. In Arizona, this can involve various scenarios and parties.
Definition and Examples of Medical Malpractice
Medical malpractice involves medical negligence where a healthcare provider fails to act as a competent professional would under similar circumstances. Examples include surgical errors, misdiagnosis, or medication mistakes. Another common example is anesthesia errors, which can lead to severe complications or even death if not properly administered or monitored. Birth injuries, resulting from negligent prenatal care or delivery practices, also constitute a significant category of malpractice claims. Also, failure to obtain informed consent before a procedure can form the basis of a malpractice claim if the patient was not adequately informed of the risks involved.
Who Can Be Sued for Medical Malpractice?
In Arizona, you can sue doctors, nurses, hospitals, and other healthcare providers for malpractice. The key is proving their actions deviated from accepted medical standards. This includes not only individuals but also entities such as hospitals, clinics, and even pharmaceutical companies if they have played a role in the negligence. For example, if a hospital fails to maintain sanitary conditions leading to an infection, they can be held liable. Likewise, if a nurse administers the wrong medication because of a doctor's unclear handwriting on a prescription, both the nurse and the doctor may be liable, depending on the circumstances.
How to File a Medical Malpractice Lawsuit in Arizona
Filing a medical malpractice lawsuit involves several steps and requirements. Understanding this process can help you handle your case effectively.
Steps to Take Before Filing a Lawsuit
- Gather Medical Records: Obtain all relevant documents related to the alleged malpractice, including charts, test results, and any correspondence with healthcare professionals.
- Consult an Attorney: Seek legal advice to assess your case and potential outcomes. An experienced attorney will help you understand the viability of your claim and guide you through the process.
- Obtain Expert Review: Under A.R.S. § 12-2603, secure an affidavit from a medical expert supporting your claim. This expert should have a background in the same field as the defendant to confirm your claim effectively.
- Assess Damages: Assess the full extent of your damages, including future medical costs and long-term impacts on your quality of life.
Filing the Lawsuit: A Step-by-Step Guide
- File a Complaint: Submit your legal complaint to the appropriate Arizona court. Make sure that your complaint clearly outlines the allegations and the basis for the malpractice claim.
- Serve the Defendant: Make sure the healthcare provider is notified of the lawsuit. This step is essential as it formally informs them of the legal action being taken.
- Discovery Phase: Exchange information and gather evidence from both parties. This phase may involve depositions, subpoenas, and interrogatories to build a strong case.
- Trial Preparation: Prepare for court proceedings, including securing expert witnesses. This involves rehearsing testimonies and ensuring that all evidence is well-organized and readily accessible.
Arizona's Statute of Limitations for Medical Malpractice
The statute of limitations is a important factor in medical malpractice cases, dictating how long you have to file a lawsuit.
Understanding the Discovery Rule
Arizona's statute of limitations for medical malpractice is usually two years (A.R.S. § 12-542). But, the discovery rule may extend this period if the injury was not immediately apparent. This rule is particularly relevant in cases where symptoms of the malpractice appear long after the event, such as in the case of a surgical instrument left inside a patient. In such scenarios, the statute of limitations may begin when the patient discovers or should have reasonably discovered the injury.
Exceptions to the Statute of Limitations
Certain exceptions apply, such as cases involving minors or fraudulent concealment by the healthcare provider. In cases involving minors, the statute of limitations typically begins when the child turns 18. Also, if a healthcare provider actively conceals their negligence, the limitation period may be tolled until the patient uncovers the fraud. Consulting with a medical malpractice attorney can clarify your specific situation and help determine the applicable time frame for your case.
Requirements for Expert Testimony in Arizona
Expert testimony is often essential in medical malpractice cases to establish a breach of standard care.
Why Expert Testimony is Crucial
Experts provide insight into what a competent healthcare provider would have done under similar circumstances. Their testimony helps the court understand complex medical issues. For instance, they can explain medical jargon, the usual protocols for a specific treatment, and how the defendant's actions deviated from these standards. This testimony can often be the linchpin for establishing negligence and demonstrating how it directly caused harm to the patient.
How to Obtain an Expert Affidavit
An expert affidavit must outline the basis for the malpractice claim, as required by A.R.S. § 12-2603. Your attorney will typically help secure this affidavit from a qualified medical professional. The expert selected should be someone with relevant experience and credentials to speak authoritatively on the matter. The affidavit should include detailed explanations and be backed by evidence or medical literature to strengthen the credibility of the claim.
Damages in Arizona Medical Malpractice Cases
Damages compensate for losses suffered because of medical negligence. Understanding the types and implications is essential for your claim.
Types of Damages You Can Claim
Damages can include:
- Economic damages: These cover tangible losses such as medical bills, future medical expenses, and lost wages. They are calculated based on actual financial losses and can include costs for rehabilitation and therapy.
- Non-economic damages: These cover intangible losses such as pain and suffering, emotional distress, and loss of enjoyment of life. Calculating these damages can be subjective, but they reflect the impact of malpractice on your quality of life.
- Punitive damages: In cases of gross negligence or willful misconduct, punitive damages may be awarded to punish the defendant and deter similar behavior in the future.
No Cap on Damages: What It Means for Your Case
Arizona does not cap damages in medical malpractice cases, potentially allowing for significant compensation depending on the case specifics. This absence of a cap means that if the malpractice has resulted in severe, life-altering consequences, the jury or judge has the discretion to award an amount that fully addresses the scope of harm suffered. This can lead to substantial awards, especially in cases involving catastrophic injuries.
Common Types of Medical Malpractice Claims
Different types of medical errors can lead to malpractice claims. Understanding these can guide your approach to a lawsuit.
Diagnostic Errors
Misdiagnosis or delayed diagnosis can lead to improper treatment and severe patient harm. This is a common basis for malpractice claims. For instance, a delayed diagnosis of cancer can result in the progression of the disease to a stage where it becomes untreatable. Likewise, a misdiagnosis can lead to unnecessary treatments or surgeries, causing additional harm to the patient. These errors often stem from failure to order appropriate tests or misinterpretation of test results.
Surgical Mistakes
Errors during surgery, such as operating on the wrong site or leaving instruments inside the body, can have devastating effects. These mistakes can lead to additional surgeries, infections, and sometimes permanent disability. Other surgical errors include nerve damage, anesthesia errors, and unnecessary procedures. Each of these mistakes can drastically impact a patient's recovery and future health, making thorough documentation and expert testimony important in these cases.
Shared Fault and Comparative Negligence in Arizona
Arizona uses a comparative negligence system, which can impact the compensation you receive.
How Fault is Determined
Courts assess the degree of fault for each party involved. Under A.R.S. § 12-2505, your compensation may decrease if you share any fault. This comparative negligence principle means that if you are found to be 20% at fault for your injury, your compensation will be reduced by that percentage. In medical malpractice cases, this might involve scenarios where a patient did not follow medical advice, contributing to their own harm.
Impact on Your Compensation
If you are found partially at fault, your award may reduce proportionally to your responsibility for the injury. For example, if the total damages are $100,000 and you are deemed 30% responsible, you would receive $70,000. Understanding this legal principle is essential when discussing potential settlement offers or preparing for trial, as it directly influences the financial outcome of your case.
When to Hire a Medical Malpractice Lawyer
Hiring a lawyer can significantly affect the outcome of your case, especially when navigating complex legal processes.
Signs You Need Legal Help
Consider legal assistance if:
- The case involves substantial medical records and expert testimony, requiring specialized knowledge to make sense of and present effectively.
- You face resistance from healthcare providers or insurance companies who might attempt to minimize your claim or deny liability.
- You are unsure about the statute of limitations or evidence requirements, which can significantly impact the viability and success of your lawsuit.
- The potential damages are substantial, necessitating professional handling to ensure maximum compensation.
