Purpose:
Medical errors in radiation oncology (RO) practice have received significant national attention over the last decade. Medical errors can lead to malpractice cases. Better characterizing these events can educate providers with the goal of improving patient care.
Methods And Materials:
The Controlled Risk Insurance Company Strategies' Comparative Benchmarking System (CBS) represents approximately 30% of all closed US malpractice cases and includes the experience of more than 30 academic hospitals. Registered nurses trained as clinical taxonomy specialists code each case, and individual case-level details are available. Practicing radiation oncologists extracted all closed RO cases from years 2005 to 2014 and subgrouped them by patient allegation category, clinical injury severity, care setting and academic affiliation, disease site and natural history, treatment modality, and contributing factor. Within categories, χ2 tests were used to test for the variables' association with an indemnity payment.
Results:
RO was the primary service in 102 closed cases (0.2% of all cases in the CBS), accounting for $13,323,578 in indemnity payments (0.1% of all payments in the CBS). The median indemnity payment was $100,000. Head-and-neck and central nervous system tumors accounted for 23.9% and 10.9% of all RO cases, respectively, and 41.3% and 31.4% of all indemnity payments, respectively. Benign diseases and brachytherapy were involved in 12.0% and 15.2% of cases, respectively. Cases involving benign disease (P = .009), treatment of the wrong site (P = .001), or treatment using the wrong dose (P < .001) were all associated with indemnity payments. The top 5 most expensive cases accounted for nearly 80% of all indemnity payments, and all involved head-and-neck, central nervous system, benign, or brachytherapy cases.
Conclusions:
We found that although closed malpractice cases involving RO are rare events, certain populations may be overrepresented in closed claims. These data can help inform providers and systems with the goal of ultimately improving patient safety.
Insights
Medical errors in radiation oncology (RO) are rare but can lead to significant malpractice costs. Certain patient groups, like those with head-and-neck or central nervous system tumors, are overrepresented in these claims, highlighting areas for improved patient safety.
Area of Science:
- Medical Malpractice
- Radiation Oncology
- Patient Safety
Background:
- Medical errors in radiation oncology (RO) have gained national attention.
- Understanding these errors is crucial for improving patient care and reducing malpractice cases.
- Characterizing closed malpractice claims provides insights into RO practice vulnerabilities.
Purpose of the Study:
- To analyze closed malpractice cases in radiation oncology.
- To identify patient populations and treatment factors associated with indemnity payments.
- To inform providers and systems for enhanced patient safety in RO.
Main Methods:
- Utilized the Controlled Risk Insurance Company Strategies' Comparative Benchmarking System (CBS) data from 2005-2014.
- Extracted and analyzed 102 closed RO cases, coding them by allegation, injury severity, care setting, disease site, treatment modality, and contributing factors.
- Applied chi-squared tests to determine associations between case variables and indemnity payments.
Main Results:
- Radiation oncology cases constituted 0.2% of all closed malpractice cases in the CBS, with $13.3 million in indemnity payments.
- Head-and-neck and CNS tumors, benign diseases, and brachytherapy were overrepresented in RO malpractice claims.
- Treatments for benign disease, wrong-site treatment, and wrong-dose treatment were significantly associated with indemnity payments.
Conclusions:
- Closed malpractice cases in radiation oncology are infrequent but certain patient groups are disproportionately affected.
- Specific factors like benign disease treatment and errors in site or dose are linked to higher indemnity payments.
- These findings can guide interventions to improve patient safety and reduce medical errors in radiation oncology practice.
