Postoperative complications and their association with post-traumatic stress disorder in academic vascular surgeons.

OBJECTIVES: Postoperative complications are an inherent component of surgical practice. This study seeks to address their association with emotional responses of academic vascular surgeons. METHODS: An anonymous electronic survey was sent to all vascular surgery program directors in North America with a request to disseminate to their faculty. The survey captured data on demographics and practice type and used imbedded validated measures to determine emotional responses to postoperative complications and to assess coping mechanisms. Univariate analysis was performed to determine differences between those who reported at least partial symptoms of post-traumatic stress disorder (PTSD) following their worse major complication over the previous year and those who did not. Multivariable logistic regression analysis was performed for all covariates found significant on univariate analysis, and those deemed clinically relevant. RESULTS: The survey was distributed to 267 faculty at 128 institutions in the United States and 10 institutions in Canada and completed by 65 participants (response rate, 32%). Twenty of 65 (31%) identified as female, and the total group had a mean age of 47 ± 10.2 years. Most respondents (43/65; 66%) reported a major complication within 3 months of the survey, with the majority of respondents (45/65; 69%) reporting the outcome of patient mortality. Of respondents, 20 of 65 (31%) demonstrated at least partial symptoms of PTSD in response to the worst complication from the previous year, with 12 of 65 (19%) meeting the clinical diagnosis of PTSD. Respondents in the PTSD group were more likely to criticize/blame themselves following the complication (P = .0028); less likely to identify the complication as "expected" (P = .048) or to believe causes of their complications were due to others/external factors; and more likely to identify as a female (55% vs 20%; P = .008). Regarding support following major complications, most respondents (57/65; 88%) desired the ability to discuss details of the case with a respected peer. The most common external pressure influencing their emotional responses to complications was maintaining reputation and a sense of honor (66%). Gender differences persisted on multivariate analysis (P = .016). CONCLUSIONS: Emotional responses following major postoperative complications in vascular surgery are common and may pose a risk for PTSD. This may occur more commonly following complications that are unexpected or in cases in which the cause of the complication was due to a perceived or actual surgical mistake. The ubiquitous nature and severity of the emotional toll of major complications for vascular surgeons is poorly described and under-recognized. Gender-related differences may exist, and most surgeons desire a support network of respected peers with whom to discuss complications.

A non-canonical retina-ipRGCs-SCN-PVT visual pathway for mediating contagious itch behavior.

Contagious itch behavior informs conspecifics of adverse environment and is crucial for the survival of social animals. Gastrin-releasing peptide (GRP) and its receptor (GRPR) in the suprachiasmatic nucleus (SCN) of the hypothalamus mediates contagious itch behavior in mice. Here, we show that intrinsically photosensitive retina ganglion cells (ipRGCs) convey visual itch information, independently of melanopsin, from the retina to GRP neurons via PACAP-PAC1R signaling. Moreover, GRPR neurons relay itch information to the paraventricular nucleus of the thalamus (PVT). Surprisingly, neither the visual cortex nor superior colliculus is involved in contagious itch. In vivo calcium imaging and extracellular recordings reveal contagious itch-specific neural dynamics of GRPR neurons. Thus, we propose that the retina-ipRGC-SCN-PVT pathway constitutes a previously unknown visual pathway that probably evolved for motion vision that encodes salient environmental cues and enables animals to imitate behaviors of conspecifics as an anticipatory mechanism to cope with adverse conditions.

Malpractice litigation in elective lumbar spinal fusion: a comprehensive review of reported legal claims in the U.S. in the past 50 years.

BACKGROUND CONTEXT: In the U.S., medical malpractice litigation is associated with significant financial costs and often leads to the practice of defensive medicine. Among medical subspecialities, spine surgery is disproportionately impacted by malpractice claims. PURPOSE: To provide a comprehensive assessment of reported malpractice litigation claims involving elective lumbar spinal fusion (LSF) surgery during the modern era of spine surgery instrumentation in the U.S., to identify factors associated with verdict outcomes, and to compare malpractice claims characteristics between different approaches for LSF. STUDY DESIGN/SETTING: A retrospective review. PATIENT SAMPLE: Patients undergoing elective lumbar spinal fusion surgery. OUTCOME MEASURES: The primary outcome measure was verdict outcome (defendant vs. plaintiff verdict). Secondary outcome measures included alleged malpractice, injury/damage claimed, and award payouts. METHODS: The Westlaw legal database (Thomson Reuters, New York, NY, USA) was queried for verdict and settlement reports pertaining to elective LSF cases from 1970 to 2021. Data were collected regarding patient demographics, surgeon specialty, fellowship training, state/region, procedure, institutional setting (academic vs. community hospital), alleged malpractice, injury sustained, case outcomes, and monetary award. RESULTS: A total of 310 cases were identified, yielding 67% (n=181) defendant and 24% (n=65) plaintiff verdicts, with 9% (n=26) settlements. Neurosurgeons and orthopedic spine surgeons were equally named as the defendant (45% vs. 51% respectively, p=0.59). When adjusted for inflation, the median final award for plaintiff verdicts was $1,241,286 (95% CI: $884,850-$2,311,706) while the median settlement award was $925,000 (95% CI: $574,800-$1,787,130), with no stastistically significant differences between verdict and reported settlement payouts (p=0.49). The Northeast region displayed significantly higher award payouts compared to other U.S. regions (p=0.02). There were no associations in awards outcomes when comparing alleged malpractice, alleged injuries/damages, institutional setting, surgical procedures, and surgeon specialty or fellowship training. The most common claims were intraoperative error (28%, n=107) followed by failure to obtain informed consent (24%, n=94). In the analyzed cohort, the most common injuries leading to litigation were refractory pain and suffering (37%, n=149) followed by permanent neurological deficits (26%, n=106). There were no differences in alleged malpractice or injury sustained between cases in which the outcome was favorable to defendant versus plaintiff. Anterior lumbar interbody fusion (ALIF) cases were 2.75 times more likely to be cited for excessive or inappropriate surgery (OR: 2.75 [95% CI: 1.14, 6.86], p=0.02) when compared to posterior surgical approaches. CONCLUSION: The results of our analysis of reported claims suggest that medical malpractice litigation involving elective LSF is associated with jury verdicts over $1 million per case, with the most common alleged malpractice being intraoperative error and failure to obtain informed consent. Surgeon specialty, fellowship training, procedure type, and institution type were not associated with greater litigation risks; however, ALIF surgery had a significantly higher risk of involving claims of excessive or inappropriate surgery compared to posterior approaches for lumbar fusion. In addition, claims were significantly higher in the Northeast compared to other U.S. regions. Efforts to improve patient education through shared-decision making and proactive strategies to avoid, detect, and mitigate intra-operative procedural errors may decrease the risk of litigation in elective LSF.
