Examining Time to Initiation of Biologic Disease-modifying Antirheumatic Drugs and Medication Adherence and Persistence Among Texas Medicaid Recipients With Rheumatoid Arthritis.
Little is known about the transition from nonbiologic disease-modifying antirheumatic drugs (DMARDs) to biologic DMARDs or about individual nonbiologic DMARD use patterns among patients with rheumatoid arthritis (RA). This study examined time to initiation of biologic DMARDs and nonbiologic DMARD medication adherence and persistence among Texas Medicaid recipients with RA taking nonbiologic DMARDs. ⋯ These results should be interpreted in light of some study limitations, such as using proportion of days covered as a proxy for adherence, not having clinical data to control for RA severity, and lack of generalizability to all US populations. Given the study findings, both clinicians and other decision makers may want to investigate the potential driving factors of initiation of biologic DMARDs to provide effective RA management and consider patient education programs to enhance medication adherence and persistence to RA medications.

Meta Analysis Comparative StudyCost-effectiveness of Apixaban Versus Other Oral Anticoagulants for the Initial Treatment of Venous Thromboembolism and Prevention of Recurrence.
To assess the cost-effectiveness of apixaban versus rivaroxaban, low-molecular-weight heparin (LMWH)/dabigatran, and LMWH/vitamin K antagonist (VKA) for the initial treatment and prevention of recurrent thromboembolic events in patients with venous thromboembolism (VTE). ⋯ The assessment of the effects and costs of apixaban in this study predicted that apixaban is a dominant alternative to rivaroxaban and LMWH/dabigatran and a cost-effective alternative to LMWH/VKA for 6 months of treatment of VTE and the prevention of recurrence.

ReviewCeftazidime-Avibactam: A Novel Cephalosporin/β-Lactamase Inhibitor Combination for the Treatment of Resistant Gram-negative Organisms.
Multidrug-resistant gram-negative bacterial infections have emerged as a major threat in hospitalized patients. Treatment options are often inadequate and, as a result, these infections are associated with high mortality. A cephalosporin and a novel synthetic non-β-lactam, β-lactamase inhibitor, ceftazidime-avibactam, is approved for the treatment of serious infections caused by resistant gram-negative bacteria. This article reviews the spectrum of activity, clinical pharmacology, pharmacodynamic and pharmacokinetic properties, clinical efficacy and tolerability, and dosing and administration of ceftazidime-avibactam. ⋯ Currently, ceftazidime-avibactam is approved for the indications of complicated intra-abdominal infections (with metronidazole) and complicated urinary tract infections. Clinical trials published to date on this antimicrobial agent have shown its excellent safety and tolerability. This new combination agent has a role, but its use should be limited to patients without other treatment options in the empiric and documented treatment of multidrug-resistant gram-negative organisms. Further investigation is needed in patients with carbapenemase-producing Enterobacteriaceae and multidrug-resistant P aeruginosa who have bacteremia or nosocomial or ventilator-associated pneumonia. It is imperative that ceftazidime-avibactam be used in a responsible manner so that its effectiveness can be retained.

Impact of an Antimicrobial Stewardship Program on Patient Safety in Veterans Prescribed Vancomycin.
This study aimed to determine the safety impact of an antimicrobial stewardship program (ASP) on vancomycin-associated nephrotoxicity and to examine risk factors contributing to the development of toxicity. ⋯ ASPs represent an important aspect of a patient-safety initiative in order to reduce vancomycin-associated nephrotoxicity. Concurrent piperacillin/tazobactam therapy, surgical service, and elevated maximum trough concentration were risk factors for nephrotoxicity.
