Educational Value of Ultrasonography Used as a Diagnostic Tool by Medical Students at a Student-Run Free Clinic.

At A.T. Still University's Kirksville College of Osteopathic Medicine, Still Caring Health Connection is a student-run organization that hosts free clinic nights for the underserved. The clinics are beneficial for patients and medical students because patients receive needed medical attention and medical students get early clinical exposure. During the clinics, medical students use portable ultrasound machines to guide diagnoses. When surveyed about their use of ultrasound on clinic nights, most students responded positively.

Medication adherence and rejection rates in older vs younger adult liver transplant recipients.

A growing number of older adults are undergoing liver transplantation (LT) in the United States. In some settings, it is thought that adherence declines with age. This retrospective study examined adherence and clinical outcomes in older vs younger adult LT recipients. Medical records of adult LT recipients from 2009 to 2012 from a single urban center were reviewed. The medication level variability index (MLVI) was the predefined primary outcome, with nonadherence defined as MLVI >2.5. The secondary outcome was incidence of rejection. Outcomes were evaluated starting 1 year post-LT until 2015. A total of 42 of 248 patients were ≥65 at transplant. Older adults had significantly better adherence than younger ones (65%≥65 were adherent vs 42% younger adults; chi-square two-tailed P=.02). Survival analyses of rejection between age groups censored by time since transplant showed no difference among the four age groups (χ2 =0.84, P=.84). Older age was not found to be a risk factor for reduced adherence or graft rejection in patients surviving at least 1 year post-LT.

Pretransplant Psychosocial Risk Factors May Not Predict Late Nonadherence and Graft Rejection in Adult Liver Transplant Recipients.

OBJECTIVE: A psychosocial evaluation before liver transplant aims to identify risk factors for nonadherence and poor outcomes posttransplant. Despite broad support for such evaluations, evidence justifying its components is thus far limited. We investigated whether variables assessed during the psychosocial evaluation before liver transplant predict immunosuppressant nonadherence and graft rejection. MATERIALS AND METHODS: Our study included 248 adult liver recipients at least 1 year after transplant with at least 3 measured tacrolimus levels. Predictor variables from the pretransplant evaluation were defined a priori and included sociodemographic factors (age, race, time since transplant), psychiatric history, substance abuse history, education level, and social support. Nonadherence was determined using the medication level variability index, which is an objective measure of adherence reflective of high medication level fluctuation from nonadherence. Outcomes (medication level variability index and biopsy-confirmed rejection) were obtained 1-year posttransplant to the present. RESULTS: We found that 50% of patients were nonadherent to tacrolimus (medication level variability index > 2.5). The 41 patients with rejection (t = 2.71, P < .01) and black patients (F = 3.10, P = .02) had significantly higher index scores. Time since transplant was correlated with medical level variability index (r = 0.15, P = .02). However, in logistic regression, none of the predefined psychosocial variables predicted nonadherence (P = .40) or rejection (P = .19). CONCLUSIONS: Our results confirmed a significant association between medication level variability index and rejection, validating it as an objective measure of clinically significant nonadherence. In a large sample with high rates of nonadherence, none of the pretransplant psychosocial variables commonly used in standard liver transplant evaluations predicted nonadherence or rejection. These findings call into question current selection criteria. Future prospective studies are needed to investigate more com-prehensive psychosocial variables and their ability to determine posttransplant outcomes.
