Abstract
BACKGROUND Antimicrobial therapy is among the mainstream treatment modalities employed in clinical settings. Antimicrobial sensitivity of the pathogen and patient compliance are key determinants of the efficacy of antimicrobial therapy. OBJECTIVE In this study, we sought to investigate the factors that affect patient compliance to antimicrobial therapy in a Chinese teaching hospital to enhance patient compliance and to prevent abuse and misuse of antibiotics by patients. METHODS A questionnaire survey was conducted among patients willing to answer all the questions who were prescribed antimicrobial drugs orally, and for whom at least half of the duration of therapy was not under the supervision of a doctor or nurse. Data analyses were performed using Kruskal-Wallis test and multivariate logistic regression. RESULTS A total of 720 patients participated in the survey; of these, 714 patients provided complete data and were included in the analysis. Up to 86.97% of patients showed noncompliance to antimicrobial therapy (total compliance score < 8), whereas 13.03% of patients showed good compliance (total compliance score = 8). On multivariate analyses, understanding of the treatment was an important factor associated with compliance. CONCLUSIONS A range of factors were associated with compliance to antimicrobial therapy, including understanding of the treatment, gender, age, home address, education level, and family income.

Pharmacokinetics and dosing estimation of meropenem in Japanese patients receiving continuous venovenous hemodialysis. J Infect Chemother 2015; 21:476-8. [PMID: 25869915 DOI: 10.1016/j.jiac.2015.02.011] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/08/2014] [Revised: 02/18/2015] [Accepted: 02/23/2015] [Indexed: 11/30/2022]
Abstract
The pharmacokinetics of meropenem have not yet been examined in Japanese patients receiving Continuous venovenous hemodialysis (CVVHD). The aim of this clinical investigation was to determine the pharmacokinetic parameters of meropenem in critically ill patients receiving CVVHD in order to estimate dosing regimens for the patient population in Japan. The values of pharmacokinetic parameters were 17.5 ± 5.6 l for V1, 1.27 ± 0.38 h(-1) for K12, 0.71 ± 0.40 h(-1) for K21 and 0.17 ± 0.02 h(-1) for K10. Based on these mean parameters (V1, K12, K21 and K10), time above MIC (T > MIC) values were estimated at different MICs using various meropenem regimens. For bacteria with a meropenem MIC of ≤ 2 μg/ml, a dosing regimen of 0.25 g every 24 h achieved more than 40% T > MIC. For a MIC of 4 μg/ml, all the regimens tested, except for 0.25 g every 24 h, achieved more than 40% T > MIC. For a MIC of 16 μg/ml, dosing regimens of 0.5 g every 8 h, 1 g every 12 h, and 1 g every 8 h achieved 40% T > MIC, reaching the pharmacokinetic-pharmacodynamic target range. This is the first study to examine the pharmacokinetics of meropenem under a CVVHD setting in Japan. The pharmacokinetic-pharmacodynamic profile of dosing regimens tested in this study will assist in selecting the appropriate meropenem regimens for patients receiving CVVHD.
