Medicolegal Consideration to Prevent Medical Malpractice Regarding Opioid Administration: An Analysis of Judicial Opinion in South Korea

Bibliometric Analysis of Research Articles on Virtual Reality in the Field of Pain Medicine Published from 1993 to 2022

Purpose

This study aims to analyze global and regional (China, Japan, and South Korea) research on virtual reality (VR) in the field of pain medicine over the past 30 years. Specifically, we quantify VR-related publications, examine the distribution of research topics on chronic and acute pain, and identify trends and future directions.

Methods

The Web of Science Core Collection (WoSCC) database was used for bibliometric analysis. This study included articles written in English between 1993 and 2022. The search strategy used predefined terms related to VR and pain. Based on the articles' titles and abstracts, two pain physicians independently reviewed and classified them as acute or chronic pain. Quantitative data on countries, institutions, journals, and research categories were analyzed. VOSviewer software was used for keyword mapping and clustering.

Results

We analyzed 808 VR-related articles on pain medicine. Over the past three decades, the number of publications in this field has increased steadily. The United States of America (n = 259) had the highest number of publications. Moreover, China (n = 42), Japan (n = 18), and South Korea (n = 24) also contributed continuously. Acute and chronic pain research accounted for 44.2% and 37.9% of the articles, respectively. The most common acute pain topic was procedure-related (n = 129, 16.0%), whereas the most common chronic pain topic was neuropathic (n = 104, 12.9%). Keywords clustered around neuroscience, pediatric pain management, and chronic pain management.

Conclusion

Our study revealed academic achievements and growing interest in VR-related research in pain medicine. Researchers worldwide have shown balanced interest in applying VR technology to acute and chronic pain, with specific contributions from China, Japan, and South Korea. Harnessing VR technology is promising for improving pain management and enhancing patients' quality of life in the field of pain medicine.

Actual situation and prescribing patterns of opioids by pain physicians in South Korea

Background

Use of opioids for chronic intractable pain is increasing globally, and their proper use can improve patients’ quality of life. In contrast, opioid use disorders, such as abuse or addiction, caused by prescribing opioids, are a worldwide issue. This study aimed to understand current opioid prescribing patterns and pain physicians’ experiences with opioid use in South Korea.

Methods

Pain physicians in 42 university hospitals in South Korea were asked to complete anonymous questionnaires regarding opioid prescriptions.

Results

A total of 69 surveys were completed. Most pain physicians started prescribing opioids at a pain score of 7/10 and aimed to reduce pain by 50%. Most physicians (73.1%) actively explained the prescribed medications and possible side effects, and 61.2% of physicians preferred the prescription interval of 4 weeks. Immediate-release opioids were the most popular treatment for breakthrough pain (92.6%). The most common side effect encountered by physicians was constipation (43.3%), followed by nausea/vomiting (34.3%). Of the physicians, 56.5% replied that addiction and misuse prevalences were less than 5%. However, the most concerning side effect was addiction (33.0%).

Conclusions

The survey results showed that the prescribing patterns of pain physicians generally followed Korean guidelines. Physicians were most interested in the safety and effectiveness of opioid prescriptions. They were most concerned about respiratory depression and abuse or addiction. A significant number of physicians agreed that the NHIS regulations needed improvement for patient convenience and safe and effective treatment, though there were pros and cons of the NHIS restrictions on prescription conditions.

An Analysis of Judicial Cases Concerning Analgesic-Related Medication Errors in the Republic of Korea

OBJECTIVES

Analgesic-related medication errors can be a threat to patient safety. This study aimed to identify and describe medication errors that can cause serious adverse drug events (ADEs) related to analgesic use.

METHODS

This retrospective, observational, medicolegal study analyzed closed cases concerning complications induced by medication errors involving 3 commonly used analgesics: opioids, nonsteroidal anti-inflammatory drugs (NSAIDs), and acetaminophen (AAP). Cases closed between 1994 and 2019 that were available in the Korean Supreme Court judgment database system were included. Medication errors were categorized using a classification system (developed by our group) based on the stage of drug administration. Clinical characteristics and judgment statuses were analyzed.

RESULTS

A total of 71 cases were included in the final analysis (opioids, n = 30; NSAIDs, n = 35; AAP, n = 6). Among them, 43 claims (60.6%) resulted in payments to the plaintiffs, with a median payment of $86,607 (interquartile range, $34,554-$193,782). The severity of ADEs was high (National Association of Insurance Commissioners scale ≥6) in 88.7% (n = 63) of claims, with a total of 44 (62%) deaths. The most common types of ADEs associated with opioid, NSAID, and AAP use were respiratory depression, anaphylactic shock, and fulminant hepatitis, respectively. The most common recognized medication errors associated with opioid, NSAIDs, and AAP were inappropriate patient monitoring (n = 10; 33.3%), improper analgesic choice (n = 15; 42.9%), and inappropriate treatment after ADEs (n = 3; 50%), respectively.

CONCLUSIONS

Our findings indicate that efforts should be made to reduce medication errors related to analgesic use to prevent permanent injury and potential malpractice claims.

Analysis of endotracheal intubation-related judicial precedents in South Korea

Background

Medical malpractice during endotracheal intubation can result in catastrophic complications. However, there are no reports on these severe complications in South Korea. We aimed to investigate the severe complications associated with endotracheal intubation occurring in South Korea, via medicolegal analysis.

Methods

We retrospectively analyzed the closed judicial precedents regarding complications related to endotracheal intubation lodged between January 1994 and June 2020, using the database of the Supreme Court of Korea. We collected clinical and judicial characteristics from the judgments and analyzed the medical malpractices related to endotracheal intubation.

Results

Of 220 potential cases, 63 were included in the final analysis. The most common event location was the operating room (n = 20, 31.7%). All but 3 cases were associated with significant permanent or more severe injury, including 31 deaths. The most common problems were failed or delayed intubation (n = 56, 88.9%). Supraglottic airway device was used in 5.2% (n = 3) cases of delayed or failed intubation. Fifty-one (81%) cases were ruled in favor of the plaintiff in the claims for damages, with a median payment of Korean Won 133,897,845 (38,000,000, 308,538,274). The most common malpractice recognized by the court was that of not attempting an alternative airway technique (n = 32, 50.8%), followed by violation of the duty of explanation (n = 10, 15.9%).

Conclusions

Our results could increase physicians’ awareness of the major complications related to endotracheal intubation and help ensure patient safety.
