Cost-effectiveness of subdermal implantable buprenorphine versus sublingual buprenorphine to treat opioid use disorder

Aims: Subdermal implantable buprenorphine (BSI) was recently approved to treat opioid use disorder (OUD) in clinically-stable adults. In the pivotal clinical trial, BSI was associated with a higher proportion of completely-abstinent patients (85.7% vs 71.9%; p?=?.03) vs sublingual buprenorphine (SL-BPN). Elsewhere, relapse to illicit drug use is associated with diminished treatment outcomes and increased costs. This study evaluated the cost-effectiveness of BSI vs SL-BPN from a US societal perspective.

Methods: A Markov model simulated BSI and SL-BPN cohorts (clinically-stable adults) transiting through four mutually-exclusive health states for 12 months. Cohorts accumulated direct medical costs from drug acquisition/administration; treatment-diversion/abuse; newly-acquired hepatitis-C; emergency room, hospital, and rehabilitation services; and pediatric poisonings. Non-medical costs of criminality, lost wages/work-productivity, and out-of-pocket expenses were also included. Transition probabilities to a relapsed state were derived from the aforementioned trial. Other transition probabilities, costs, and health-state utilities were derived from observational studies and adjusted for trial characteristics. Outcomes included incremental cost per quality-adjusted-life-year (QALY) gained and incremental net-monetary-benefit (INMB). Uncertainty was assessed by univariate and probabilistic sensitivity analysis (PSA).

Results: BSI was associated with lower total costs (?$4,386), more QALYs (+0.031), and favorable INMB at all willingness-to-pay (WTP) thresholds considered. Higher drug acquisition costs for BSI (+$6,492) were outpaced, primarily by reductions in emergency room/hospital utilization (?$8,040) and criminality (?$1,212). BSI was cost-effective in 89% of PSA model replicates, and had a significantly higher NMB at $50,000/QALY ($20,783 vs $15,007; p?Conclusions: BSI was preferred over SL-BPN from a health-economic perspective for treatment of OUD in clinically-stable adults. These findings should be interpreted carefully, due to some relationships having been modeled from inputs derived from multiple sources, and would benefit from comparison with outcomes from studies that employ administrative claims data or a naturalistic comparative design.

Extending the scope of hotel client reactions to employee injustice: Hotel employer reviews on the Internet

Third-party literature is concerned about the way others perceive what happens in organizations. When dealing with the perceived justice of the employer-employee relationship, it has mainly adopted an on-site approach. The scarce research focusing on the consequences of perceived justice for client variables in hotels has shown that it can impact client loyalty. In this study, we adopt an on-line view, and we analyze how the comments posted by hotel employees on the Internet about their work conditions influence guest perceptions. This topic is relevant because it is well known that clients’ perceptions influence client satisfaction, WOM and revisit intentions. Through an experiment based on real hotel employer reviews, results confirm that these comments have an impact on the organizational image dimension of service quality, hotel clients’ satisfaction, WOM, and revisit intentions. Thus, as occurs with client eWOM, hotel managers should be aware of these comments and manage them appropriately.

Implementation and imbalance: dealing with hangover from the Uruguay Round

The Uruguay Round agreements impose bound obligations to implement,but provide only unbound promises of assistance—is therea legal solution within the WTO legal system, i.e. can implementationassistance be made a legal obligation? The author concludesthat the Doha negotiations on trade facilitation and on aidfor trade demonstrate that such a legal arrangement cannot beconstructed. This is not, however, a problem; the internationalcommunity has provided extensive trade-related assistance throughbilateral and multilateral development agencies. Regarding theoverall Uruguay Round imbalance (developing countries gave morethan they got), failure of the international community to acknowledgethat the imbalance stems in major part from the WTO agreementon intellectual property (TRIPS) has retarded a general making-up.
