Depression, Immunosuppressant Levels, and Clinical Outcomes in Postlung Transplant Recipients.

OBJECTIVE: Posttransplant depression has been linked to increased risk for adverse outcomes in lung transplant patients. Maintaining target serum immunosuppressant levels is also essential for optimal lung transplant clinical outcome and may be a crucial predictor of outcomes. Because depression could affect medication nonadherence, resulting in out-of-range immunosuppressant levels, we examined the relationship between posttransplant depression, immunosuppressant medication trough level variability, indexed by out-of-range values on clinical outcomes and coefficient of variability, and clinical outcomes. METHOD: A consecutive series of 236 lung transplant recipients completed the Center for Epidemiological Studies-Depression two-month posttransplant. Immunosuppressant trough levels (i.e., tacrolimus or cyclosporine) within the range of individualized immunosuppressant targets were obtained at three-, six-, nine-month follow-up clinic visits. Clinical outcomes including hospitalizations and mortality were obtained from medical records. RESULTS: Fourteen percent of patients were classified as depressed (Center for Epidemiological Studies-Depression ≥16), 144 (61%) of patients had at least 25% out-of-range immunosuppressant values, and the average coefficient of variability was 36%. Over a median of 2.6 years (interquartile range = 1.2), 32 participants died (14%) and 144 (61%) had at least one unplanned, transplant-related hospitalization. Both depression (hazard ratio = 1.45 (1.19, 1.76), p < . 01) and immunosuppressant variation (immunosuppressant out-of-range: hazard ratio = 1.41 (1.10, 1.81), p < .01) independently predicted more frequent hospitalizations and higher mortality. CONCLUSIONS: Early posttransplant depression was associated with significantly worse clinical outcomes. While immunosuppressant level variability is also related to adverse outcomes, such variability does not account for increased risk observed with depression.

Parents' Knowledge and Education of Retinopathy of Prematurity in Four California Neonatal Intensive Care Units.

PURPOSE: Retinopathy of prematurity (ROP) may cause visual impairment in infants with very low birth weight. Lack of parent knowledge may contribute to gaps in screening and treatment. We studied parents' knowledge and education of ROP. DESIGN: Cross-sectional study. METHODS: Setting: Four high-acuity neonatal intensive care units in California (40-84 beds). PARTICIPANTS: Total of 194 English- and Spanish-speaking parents of very low birth weight (<1500 grams) infants recruited from September 2013 to April 2015. MAIN OUTCOME MEASURES: We asked parents what they knew about ROP, how they were educated about ROP, and their experiences obtaining outpatient eye care. We used multivariate analysis to assess whether parent knowledge was associated with level of English proficiency and literacy, education modality (verbal, written, online, video), and hospital transfer status. RESULTS: Of the 194 participants, 131 (68%) completed surveys: 18% had both limited English proficiency and low literacy while overall 26% had limited English proficiency and 37% had low literacy; 17% did not know that ROP is an eye disease, and 38% did not know that very low birth weight and prematurity are both risk factors for ROP. Parents reported receiving verbal (62%) or written (56%) information; few used online resources (12%) or videos (3%). Half reported receiving information about infants' retinopathy status at discharge. No education modality was associated with higher knowledge. Limited English proficiency and low literacy were associated with lower knowledge (vs English-proficient, literate). CONCLUSIONS: Parents of infants with very low birth weight, particularly those with limited English proficiency and low health literacy, lack knowledge about ROP.
