RESUMO
INTRODUCTION: Perioperative vision loss (POVL) is a rare but catastrophic event. Closed claim databases are useful for investigating risk factors of POVL to help guide practices in risk mitigation and risk management strategies. METHODS: We retrospectively analyzed the Controlled Risk Insurance Company (CRICO) Comparative Benchmarking System database for perioperative nerve injuries from when claims were closed between 2007 and 2016. We then extracted, deidentified, and analyzed all the POVL cases. RESULTS: Of 53 nerve injury claims closed between 2007 and 2016, we found 9 pertaining to POVL. Of these 9 cases, 100% resulted in permanent injury, 76% were associated with spine surgery, 89% of the patients were positioned prone intraoperatively, 67% were noted to have improper or missing documentation, and 56% of the patients claimed they were not informed of the risk of vision loss during preoperative consenting. Four of the 9 cases were settled, with a mean settlement amount of $906,250 (standard deviation, ± $745,647). CONCLUSIONS: POVL often results in permanent injury with costly burden on the health care system. Risk reduction strategies need to be instituted on the provider and system level, involving a multidisciplinary health care team to develop and execute clinical protocols and patient communication strategies that will help prevent POVL.

BACKGROUND: Closed malpractice claims can provide insight into low-frequency adverse events in many areas of perioperative and chronic pain care. Over the last decade, there have been changes in surgical and regional anesthetic practice, likely impacting adverse event patterns. Given the wide variability and low frequency of complications associated with peripheral nerve blocks, the study of closed malpractice claims offers an opportunity to examine adverse events, and the patient, technical, and provider factors that led to the claim. Knowledge gained from examination of closed claims has already resulted in multiple improvements in processes of care and patient safety. OBJECTIVES: An investigation of the factors that contributed to medicolegal claims against anesthesia providers related to peripheral nerve blocks. STUDY DESIGN: Retrospective analysis. SETTING: Inpatient and outpatient surgery facilities. METHODS: The Comparative Benchmarking System database is a medical liability database that contains more than 400,000 malpractice claims from more than 400 academic and community-based institutions accounting for over 30% of malpractice claims in the United States. The present investigation reviewed all (n = 113) available closed malpractice claims related to regional anesthesia (RA) in surgical patients closed between 2006 and 2016, and investigated factors that may have contributed to patient injury, including type of nerve block, type of surgery, nerves injured, resulting neurologic deficits, and potential factors contributing to the injury. RESULTS: Our data analyzed 62 claims related to RA and showed that most closed claims were classified as permanent minor injuries. The greatest number of claims were for brachial plexus injuries associated with interscalene blocks performed for shoulder or rotator cuff repairs. Femoral and sciatic nerve blocks with resulting lower extremity injuries were the most common nerve blocks resulting in payment. The largest contributing factor to these injuries was noted to be "Technical Knowledge/Performance" of the regionalist followed by "Pre-existing Injury/Radiculopathy." Symptom onset from these claims was most likely to be delayed with the leading initial presenting symptom being paresthesia. LIMITATIONS: It is difficult to establish cause-effect relationship, and the small sample size limits the ability to detect clinical differences and associations with specific comorbidities or techniques. There was also limited information related to regional anesthetic techniques and medications used that would have helped explore further relationships between the procedure and cause for litigation. CONCLUSIONS: There remains significant room for risk reduction in regional anesthetic practice. Patterns based on the analysis of closed claims show that interscalene blocks are the most common peripheral nerve block resulting in litigation, even when compared with other blocks involving the brachial plexus. Furthermore, patients with existing nerve injury/radiculopathy may also warrant alternative techniques or greater emphasis during informed consent on the increased risk of injury. As most of the presenting symptoms associated with claims are delayed, an opportunity for improvement in postregional care may be better communication with patients following discharge to discuss their postoperative recovery. KEY WORDS: Regional, pain, anesthesia, complications, closed claims, liability, nerve, block, injury.

STUDY OBJECTIVE: To provide an analysis of closed malpractice claims brought against anesthesiologists for positioning-related perioperative nerve injury (PRPNI). DESIGN: In this retrospective study, we analyzed closed claims data from the Controlled Risk Insurance Company (CRICO) Comparative Benchmarking System (CBS) database. SETTING: Closed claims involving nerve injuries that occurred between January 1, 1996 and December 31, 2015 in all surgical settings, provided the alleged damaging event occurred under general anesthesia. PATIENTS: Patient ages ranged from 23 to 94. Patients underwent a variety of surgical procedures. Severity of nerve injury ranged from "Insignificant" to "Grave" according to the NAIC Severity of Injury Code. INTERVENTIONS: None. MEASUREMENTS: Patient age and gender, alleged nerve injury type and severity, operating surgical specialty, contributing factors to the alleged nerve injury, and case outcome. Some of these data were drawn directly from coded variables in the CBS database, and some were gathered by the authors from CRICO-encoded narrative case summaries. MAIN RESULTS: Seventy-five claims were determined to represent PRPNI. Ninety-two percent of all PRPNI claims involved practitioner technical knowledge/performance. Of all the recorded nerve injuries in this series, 56% involved brachial plexus injuries, and supine patient positioning represented 55% of brachial plexus claims. Settlement payments were made in 33% of claims, and the average payment for all cases was $46,269. Twenty-four percent of PRPNI claims were found to be temporary, while 76% were permanent. CONCLUSIONS: PRPNI is multifactorial, and stems both from practitioner errors as well as from patient comorbidities and pre-existing neuropathies. Supine positioning can increase PRPNI risk. There are likely still causes of PRPNI of which we are not yet aware, given that despite concerted efforts towards positioning and padding interventions, injuries such as those described in this study still occur.

BACKGROUND: Closed malpractice claim studies allow a review of rare but often severe complications, yielding useful insight into improving patient safety and decreasing practitioner liability. METHODS: This retrospective observational study of pain medicine malpractice claims utilizes the Controlled Risk Insurance Company Comparative Benchmarking System database, which contains nearly 400,000 malpractice claims drawn from >400 academic and community medical centers. The Controlled Risk Insurance Company Comparative Benchmarking System database was queried for January 1, 2009 through December 31, 2016, for cases with pain medicine as the primary service. Cases involving outpatient interventional pain management were identified. Controlled Risk Insurance Company-coded data fields and the narrative summaries were reviewed by the study authors. RESULTS: A total of 126 closed claims were identified. Forty-one claims resulted in payments to the plaintiffs, with a median payment of $175,000 (range, $2600-$2,950,000). Lumbar interlaminar epidural steroid injections were the most common procedures associated with claims (n = 34), followed by cervical interlaminar epidural steroid injections (n = 31) and trigger point injections (n = 13). The most common alleged injuring events were an improper performance of a procedure (n = 38); alleged nonsterile technique (n = 17); unintentional dural puncture (n = 13); needle misdirected to the spinal cord (n = 11); and needle misdirected to the lung (n = 10). The most common alleged outcomes were worsening pain (n = 26); spinal cord infarct (n = 16); epidural hematoma (n = 9); soft-tissue infection (n = 9); postdural puncture headache (n = 9); and pneumothorax (n = 9). According to the Controlled Risk Insurance Company proprietary contributing factor system, perceived deficits in technical skill were present in 83% of claims. CONCLUSIONS: Epidural steroid injections are among the most commonly performed interventional pain procedures and, while a familiar procedure to pain management practitioners, may result in significant neurological injury. Trigger point injections, while generally considered safe, may result in pneumothorax or injury to other deep structures. Ultimately, the efforts to minimize practitioner liability and patient harm, like the claims themselves, will be multifactorial. Best outcomes will likely come from continued robust training in procedural skills, attention paid to published best practice recommendations, documentation that includes an inclusive consent discussion, and thoughtful patient selection. Limitations for this study are that closed claim data do not cover all complications that occur and skew toward more severe complications. In addition, the data from Controlled Risk Insurance Company Comparative Benchmarking System cannot be independently verified.

STUDY OBJECTIVE: To provide a contemporary medicolegal analysis of claims brought against anesthesia providers in the United States related to neuraxial blocks for surgery and obstetrics. DESIGN: In this retrospective analysis, we analyzed closed claims data from the Controlled Risk Insurance Company (CRICO) Comparative Benchmarking System (CBS) database between 2007 and 2016. SETTING: Closed claims from inpatient and outpatient settings related to neuraxial anesthesia for surgical procedures and obstetrics. PATIENTS: Forty-five claims were identified for analysis. These patients underwent a variety of surgical procedures, included both children and adults, and with ages ranging from 6 to 82. INTERVENTIONS: Patients receiving neuraxial anesthesia (spinals, epidurals) for surgery or obstetrics. MEASUREMENTS: Data collected includes patient demographics, alleged injury type/severity, surgical specialty, likely contributors to the alleged damaging event, and case outcome. Some of the data were drawn directly from coded variables in the CRICO database, and some were gathered from narrative case summaries. MAIN RESULTS: Settlement payments were made in 20% of claims. Reported adverse outcomes ranged from temporary minor to permanent major injuries. Most closed claims were classified as permanent minor injuries. The greatest number of claims involved residual weakness and radiculopathy resulting from epidurals. The largest contributing factor to these injuries was noted to be "Technical Knowledge/Performance" of the anesthesia provider followed by "Missing or Documentation Error." Over half of the claims arose from obstetric patients (31%) and patients undergoing orthopedic surgery (27%). CONCLUSIONS: Patients with pre-existing radiculopathy or comorbidities may warrant more thorough informed consent about the increased risk of injury. Additionally, prompt follow-up, monitoring, and documentation of post-operative symptoms, such as weakness or radiculopathy, are crucial for improving patient safety and satisfaction. More timely communication with the patient and the surgical team regarding residual neurologic symptoms is important for earlier diagnosis of injury.

A significant number of commonly administered medications in anesthesia show wide clinical interpatient variability. Some of these include neuromuscular blockers, opioids, local anesthetics, and inhalation anesthetics. Individual genetic makeup may account for and predict cardiovascular outcomes after cardiac surgery. These interactions can manifest at any point in the perioperative period and may also only affect a specific system. A better understanding of pharmacogenomics will allow for more individually tailored anesthetics and may ultimately lead to better outcomes, decreased hospital stays, and improved patient satisfaction.

There is interpatient variability to analgesic administration. Much can be traced to pharmacogenomics variations between individuals. Certain ethnicities are more prone to reduced function of CYP2D6. Weak opioids are subject to interpatient variation based on their CYP2D6 type. Strong opioids have variations based on their transport and individual metabolism. Several cytochrome enzymes have been found to be involved with ketamine but there is no strong evidence of individual polymorphisms manifesting in clinical outcomes. Nonsteroidal anti-inflammatory drugs have adverse outcomes that certain CYP variants are more prone toward. There are now recommendations for dosing based on specific genomic makeup.
