Tapering Opioid Prescription Program for High-Risk Trauma Patients: A Pilot Randomized Controlled Trial.

BACKGROUND: Chronic opioid use has been documented in up to 20% of patients with traumatic injuries. Hence, we developed the Tapering Opioids Prescription Program for high-risk Trauma (TOPP-Trauma) patients. AIMS: To assess the feasibility and acceptability of TOPP-Trauma, examine the feasibility of the research methods, and describe its potential efficacy in reducing long-term opioid use. DESIGN: A two-arm pilot randomized controlled trial. METHODS: Fifty participants discharged home were assigned to TOPP-Trauma or an educational pamphlet. Feasibility was assessed based on ability to provide the program components. The acceptability was assessed with the Treatment Acceptability and Preference Questionnaire. The feasibility of the research methods was evaluated according to standard parameters. Self-reported morphine equivalent dose (MED) and MEDs supplied by pharmacies were measured at 6 and 12 weeks. RESULTS: Eighty percent or more of TOPP-Trauma components were delivered as planned, and the program was deemed highly acceptable. Approximately 10% of screened patients were eligible. Eighty-five percent of eligible patients agreed to participate with 20% attrition rates. TOPP-Trauma participants used less MED/day compared to the control group at 6 and 12 weeks (1.2. vs. 12.2 mg; 0.4. vs 4.0 mg), and pharmacies supplied less than half of cumulative MEDs to those who received the program at 12 weeks, but the differences were not statistically significant. CONCLUSIONS: Some challenges need to be addressed before testing TOPP-Trauma. These include creating strategies to decrease attrition, offering the program throughout the care continuum to higher risk patients, and evaluating the impacts of reduced opioid use.

Neutropenia in kidney and liver transplant recipients: Risk factors and outcomes.

No studies have directly compared the key characteristics and outcomes of kidney (KTx) and liver transplantation (LTx) recipients with neutropenia. In this single-center, retrospective, cohort study, we enrolled all adult patients who received a KTx or LTx between 2000 and 2011. Neutropenia was defined as 2 consecutive absolute neutrophil count (ANC) values <1500/mm3 in patients without preexisting neutropenia. The first neutropenia episode occurring during the first year post-transplantation was analyzed. A total of 663 patients with KTx and 354 patients with LTx met the inclusion criteria. Incidence of neutropenia was 20% in KTx and 38% in LTx, respectively. High-risk CMV status and valganciclovir (VGCV) use were significant predictors of neutropenia for KTx recipients, but only VGCV use vs nonuse in LTx recipients. Neutropenia was associated with worse survival in KTx recipients (adjusted HR 1.95, 95% CI 1.18-3.22, P<.01), but not in LTx recipients (adjusted HR 0.75, 95% CI 0.52-1.10, P=.15). Sixteen acute rejection episodes were associated with preceding neutropenia in KTx recipients (HR 1.77, 95% CI 1.16-2.68, P=.007) and 24 acute rejection episodes in LTx recipients (HR 1.41, 95% CI 0.97-2.04, P=.07). Incidence of infection was similar in patients with and without neutropenia among KTx and LTx recipients.
