Medicaid Insurance Predicts Increased Postoperative Care Encounters Among Patients on Long-Term Opioid Therapy.

OBJECTIVE: This study examined the association between insurance type and postoperative unplanned care encounters among patients on long-term opioid therapy prior to surgery. SUMMARY BACKGROUND DATA: Preoperative long-term opioid therapy is associated with unique risks and poorer outcomes following surgery. To date, the extent to which insurance coverage influences postoperative outcomes in this population remains unclear. METHODS: Among individuals receiving a supply of greater than 120 total days or at least 10 opioid prescriptions in the year prior to surgery, we examined patients with Medicaid or private insurance who underwent abdominopelvic surgery from 2017 to 2021 across 70 hospitals in the state of Michigan. The primary outcome was unplanned care encounters, defined as an emergency department visit or unplanned readmission within 30 days of discharge from surgery. Multivariable logistic regression was used to assess the likelihood of acute care events with insurance type as the primary covariate of interest. RESULTS: Among 1212 patients on long-term opioid therapy prior to surgery, 45.6% (n = 553) had Medicaid insurance. Overall, one in eight (n=151) patients met criteria for a postoperative unplanned care encounter within 30 days. The probability of an unplanned encounter was 4.5 percentage points higher among patients with Medicaid insurance compared to private insurance (95% CI: 0.5%, 8.4%). CONCLUSIONS: Among patients on preoperative long-term opioid therapy, unplanned care encounters were higher among patients with Medicaid when compared to private insurance. While this is likely multifactorial, differences by insurance status may point to disparities in underlying social determinants of health and suggest the need for postoperative care pathways that address these gaps.

High-risk Prescribing Following Surgery Among Payer Types for Patients on Chronic Opioids.

OBJECTIVE: Among those on chronic opioids, to determine whether patients with Medicaid coverage have higher rates of high-risk opioid prescribing following surgery compared with patients on private insurance. BACKGROUND: Following surgery, patients on chronic opioids experience gaps in transitions of care back to their usual opioid prescriber, but differences by payer type are not well understood. This study aimed to analyze how new high-risk opioid prescribing following surgery compares between Medicaid and private insurance. METHODS: In this retrospective cohort study through the Michigan Surgical Quality Collaborative, perioperative data from 70 hospitals across Michigan were linked to prescription drug monitoring program data. Patients with either Medicaid or private insurance were compared. The outcome of interest was new high-risk prescribing, defined as a new occurrence of: overlapping opioids or benzodiazepines, multiple prescribers, high daily doses, or long-acting opioids. Data were analyzed using multivariable regressions and a Cox regression model for return to usual prescriber. RESULTS: Among 1435 patients, 23.6% (95% CI: 20.3%-26.8%) with Medicaid and 22.7% (95% CI: 19.8%-25.6%) with private insurance experienced new, postoperative high-risk prescribing. New multiple prescribers was the greatest contributing factor for both payer types. Medicaid insurance was not associated with higher odds of high-risk prescribing (odds ratio: 1.067, 95% CI: 0.813-1.402). CONCLUSIONS: Among patients on chronic opioids, new high-risk prescribing following surgery was high across payer types. This highlights the need for future policies to curb high-risk prescribing patterns, particularly in vulnerable populations that are at risk of greater morbidity and mortality.

Use of Argatroban in Donor Lung Procurement: A Case Report.

BACKGROUND Heparin-induced thrombocytopenia (HIT) is an immunological response to heparin exposure that predisposes patients to hypercoagulable reactions with subsequent heparin administration. Traditionally, heparin is the standard anticoagulant used during organ procurement to prevent clot formation in grafts. This creates a problem in donors or recipients that develop HIT as they are at risk of developing life-threatening coagulopathy. This raises the question of how to use alternative anticoagulation therapies, such as argatroban, that provide rapid-onset prophylaxis by reversibly inhibiting thrombin. Additionally, there are few studies that have assessed how recipients of multiorgan donors treated with argatroban do post-operatively. CASE REPORT In this report, we discuss the procurement protocol and hospital course of a lung transplant recipient who received a graft treated with argatroban due to a HIT-positive liver recipient. The post-operative course for our patient was uneventful, with improved lung function and no complications attributable to argatroban use. Further, none of the 4 other recipients who received organs from the same donor experienced graft dysfunctions secondary to coagulopathy, including the HIT-positive liver recipient. CONCLUSIONS The ultimate success of grafts without thromboembolic complications suggests the use of argatroban in multiorgan procurement in the setting of a HIT-positive recipient is safe and effective. This case report highlights an alternative to the traditional process of organ procurement with heparin, in which patients at risk of coagulopathies secondary to HIT are able to receive organs when traditional protocols would otherwise be prohibitive.

Trustworthiness and electrocortical processing of emotionally ambiguous faces in student police officers.

Perceptions of emotional facial expressions and trustworthiness of others guides behavior and has considerable implications for individuals who work in fields that require rapid decision making, such as law enforcement. This is particularly complicated for more ambiguous expressions, such as 'neutral' faces. We examined behavioral and electrocortical responses to facial expressions in 22 student police officers (18 males; 23.2 ± 3.63 years). Participants completed an emotional face appraisal task that involved viewing three expressions (fearful, neutral, happy) and were asked to identify the emotion and rate the trustworthiness of each face. The late positive potential (LPP), an event-related potential that tracks emotional intensity and/or salience of a stimulus, was measured during the task. Overall, participants rated neutral faces similarly to fearful faces and responded fastest to these expressions. Neutral faces also elicited a robust late LPP response that did not differ from LPP to fearful or happy faces, and there was substantial individual variation in trustworthiness ratings for neutral faces. Together, 'neutral' facial expressions elicited similar trustworthiness ratings to negatively-valenced stimuli. Brain and behavioral responses to neutral faces also varied across student officers; thus, encounters with ambiguous faces in the field may promote increased perceived threat in some officers, which may have real-world consequences (e.g., decision to shoot, risk of psychopathology).
