Background: Trust is essential in patient-physician relationships. Hospitalized patients with substance use disorders (SUDs) often experience stigma and trauma in the hospital, which can impede trust. Little research has explored the role of hospital-based addictions care in creating trusting relationships with patients with SUDs. This study describes how trust in physicians changed among hospitalized people with SUDs who were seen by an interprofessional addiction medicine service. Methods: We analyzed data from hospitalized patients with SUD seen by an addiction consult service from 2015 to 2018. Participants completed surveys at baseline and 30 to 90 days after hospital discharge. Follow-up assessments included open-ended questions exploring participant experiences with hospitalization and the addiction consult service. We measured provider trust using the Wake Forest Trust scale. We modeled trust trajectories using discrete mixture modeling, and sampled qualitative interviews from those trust trajectories. Results: Of 328 participants with SUD who had prior hospitalizations but had not previously been seen by an addiction consult service, 196 (59.8%) had both baseline and follow-up trust scores. We identified 3 groups of patients: Persistent-Low Trust, Increasing Trust, and Persistent-High Trust and 4 qualitative themes around in-hospital trust: humanizing care, demonstrating addiction expertise, reliability, and granting agency. Conclusions: Most participants retained or increased to high trust levels after hospitalization with an addiction consult service. Addiction consult services can create environments where healthcare providers build trust with, and humanize care for, hospitalized patients with SUD, and can also mitigate power struggles that hospitalized patients with SUD frequently experience.

Background: Medications for opioid use disorder (MOUD) and alcohol use disorder (MAUD) are effective and under-prescribed. Hospital-based addiction consult services can engage out-of-treatment adults in addictions care. Understanding which patients are most likely to initiate MOUD and MAUD can inform interventions and deepen understanding of hospitals' role in addressing substance use disorders (SUD). Objective: Determine patient- and consult-service level characteristics associated with MOUD/MAUD initiation during hospitalization. Methods: We analyzed data from a study of the Improving Addiction Care Team (IMPACT), an interprofessional hospital-based addiction consult service at an academic medical center. Researchers collected patient surveys and clinical data from September 2015 to May 2018. We used logistic regression to identify characteristics associated with medication initiation among participants with OUD, AUD, or both. Candidate variables included patient demographics, social determinants, and treatment-related factors. Results: Three hundred thirty-nine participants had moderate to severe OUD, AUD, or both and were not engaged in MOUD/MAUD care at admission. Past methadone maintenance treatment (aOR 2.07, 95%CI (1.17, 3.66)), homelessness (aOR 2.63, 95%CI (1.52, 4.53)), and partner substance use (aOR 2.05, 95%CI (1.12, 3.76) were associated with MOUD/MAUD initiation. Concurrent methamphetamine use disorder (aOR 0.32, 95%CI (0.18, 0.56)) was negatively associated with MOUD/MAUD initiation. Conclusions: The association of MOUD/MAUD initiation with homelessness and partner substance use suggests that hospitalization may be an opportunity to reach highly-vulnerable people, further underscoring the need to provide hospital-based addictions care as a health-system strategy. Methamphetamine's negative association with MOUD/MAUD warrants further study. [ABSTRACT FROM AUTHOR]

The article discusses research which was conducted in an effort to investigate human immunodeficiency virus infected patients' attitudes about buprenorphine treatment in office-based and opioid treatment program settings. Researchers evaluated 29 patients. They found that the patients preferred the office-based treatment to the treatment program setting treatments because they felt they were safer and more patient centered.

Objective: To determine if the increase in cerebral blood flow ("brain-sparing" effect) with fetal hypoxemia is associated with discordant hemodynamics in the upper extremities., Methods: We studied 12 fetuses with severe growth retardation, absent or reverse end-diastolic blood flow in the umbilical artery, and low pulsatility index (PI) in the middle cerebral artery, and 12 appropriately grown control fetuses with normal fetoplacental Doppler studies. The right and left brachial arteries were identified by high-resolution color Doppler ultrasonography, and the PI was measured in each brachial artery., Results: All growth-retarded fetuses had lower impedance indices in the right than in the left brachial artery (mean delta PI 1.0, 95% confidence interval [CI] 0.7-1.3, P < .001). No differences in the brachial artery impedance indices were found in control fetuses matched for gestational age (mean delta PI 0.0, 95% CI -0.2 to 0.2)., Conclusions: Left and right brachial artery blood flow velocity waveforms are discordant in fetuses with growth retardation and cerebral vasodilation. Because the right arm receives its blood supply from the same source as the brain (brachiocephalic artery) and given the proximity of the left subclavian artery to the ductus arteriosus, we speculate that this might be the result of increased blood flow into the brachiocephalic circulation and/or functional differences in the distribution of left and right ventricular output within the aortic arch in response to fetal hypoxemia.

Fetal plasma ferritin concentrations were measured in 43 normal fetuses at 18-36 weeks and in 78 blood samples collected before transfusion from 23 fetuses with Rh alloimmunization. Among controls, there was a significant correlation between fetal serum ferritin and gestational age (r = 0.39, P = .009), consistent with an increase in fetal storage of iron during normal pregnancy. In Rh-alloimmunized fetuses, the ferritin concentration was above the reference range in 63% of the samples. Before the first transfusion, the fetal ferritin concentration was increased compared with controls (mean multiples of the mean = 2.6, range 1-26) and showed a negative correlation with fetal hematocrit (r = -0.43, P less than .05), suggesting that the worse the fetal anemia, the higher the iron store. Serial transfusions were associated with further increase in serum ferritin, which correlated primarily with the total volume of blood transfused. Three fetuses had plasma serum ferritin concentrations above 1 mg/L, a level compatible with a diagnosis of iron overload in children. These observations suggest that there is a potential risk of iron overload in Rh-alloimmunized fetuses undergoing intrauterine blood transfusion.

Transabdominal fetal blood sampling under ultrasonic guidance was performed at the intrahepatic vein on 214 occasions in 177 fetuses. In 72 cases, an intravascular transfusion was also attempted at the same site. In 91.1% of the samplings, more than 1 mL of pure fetal blood was obtained, and in 89.9% of transfusions, fetal hematocrit or platelet concentration was raised to a satisfactory level. Fetal bradycardia and intraperitoneal bleeding occurred in 2.3% of the cases. Among fetuses at low risk, there was only one intrauterine death, which occurred 3 weeks after the procedure, and one spontaneous abortion in a patient with twin pregnancy. In fetuses with Rh/Kell alloimmunization or perinatal alloimmune thrombocytopenia, the survival rate was 86%. Four liver enzymes were assayed in the blood of 13 fetuses that underwent transfusions at the intrahepatic vein and 13 controls in whom the site of sampling was the umbilical vein at the placental cord insertion. No differences were found between the groups at the subsequent transfusion 2-5 weeks later. The intrahepatic vein is an alternate site of sampling/transfusion when access is difficult or failure occurs at the placental cord insertion. This approach minimizes the risks of fetal blood loss, fetomaternal hemorrhage, arterial vasospasm, and cord tamponade.
