Single Pill Regimen Leads to Better Adherence and Clinical Outcome in Daily Practice in Patients Suffering from Hypertension and/or Dyslipidemia: Results of a Meta-Analysis

Introduction!#!Cardiovascular diseases (CVD) represent the first cause of mortality in western countries. Hypertension and dyslipidemia are strong risk factors for CVD, and are prevalent either alone or in combination. Although effective substances for the treatment of both factors are available, there is space for optimization of treatment regimens due to poor patient's adherence to medication, which is usually a combination of several substances. Adherence decreases with the number of pills a patient needs to take. A combination of substances in one single-pill (single pill combination, SPC), might increase adherence, and lead to a better clinical outcome.!##!Aim!#!We conducted a meta-analysis to compare the effect of SPC with that of free-combination treatment (FCT) in patients with either hypertension, dyslipidemia or the combination of both diseases under conditions of daily practice.!##!Methods!#!Studies were identified by searching in PubMed from November 2014 until February 2015. Search criteria focused on trials in identical hypertension and/or dyslipidemia treatment as FCT therapy or as SPC. Adherence and persistence outcome included proportion-of-days-covered (PDC), medication possession ratio (MPR), time-to treatment gap of 30 and 60 days and no treatment gap of 30 days (y/n). Clinical outcomes were all cause hospitalisation, hypertension-related hospitalisation, all cause emergency room visits, hypertension-related emergency room visits, outpatient visits, hypertension-related outpatient visits, and number of patients reaching blood pressure goal. Randomized clinical studies were excluded because they usually do not reflect daily practice.!##!Results!#!11 out of 1.465 studies met the predefined inclusion criteria. PDC ≥ 80% showed an odds ratio (OR) of 1.78 (95% CI: 1.30-2.45; p = 0.004) after 6 months and an OR of 1.85 (95% CI: 1.71; 2.37; p < 0.001) after ≥ 12 months in favour to the SPC. MPR ≥ 80% after 12 months also was in favour to SPC (OR 2.13; 95% CI: 1.30; 3.47; p = 0.003). Persistence was positively affected by SPC after 6, 12, and 18 months. Time to treatment gap of 60 days resulted in a hazard ratio (HR) of 2.03 (95% CI: 1.77; 2.33, p < 0.001). The use of SPC was associated with a significant improvement in systolic blood pressure reduction, leading to a higher number of patients reaching individual blood pressure goals (FCT vs SPC results in OR = 0.77; 95% CI: 0.69; 0.85, p < 0.001). Outpatient visits, emergency room visits and hospitalisations, both overall and hypertension-related were reduced by SPC: all-cause hospitalisation (SPC vs FCT: 15.0% vs 18.2%, OR 0.79, 95% CI 0.67; 0.94, p = 0.009), all-cause emergency room visits (SPC vs FCT: 25.7% vs 31.4%, OR 0.75, 95% CI 0.65; 0.87, p = 0.001) and hypertension related emergency room visits (SPC vs FCT: 9.7% vs 14.1%, OR 0.65, 95% CI 0.54; 0.80, p < 0.001).!##!Conclusions!#!SPC improved medication adherence and clinical outcome parameter in patients suffering from hypertension and/or dyslipidemia and led to a better clinical outcome compared to FCT under conditions of daily practice

Incidence of infections due to third generation cephalosporin-resistant Enterobacteriaceae - a prospective multicentre cohort study in six German university hospitals

BackgroundInfections caused by third generation cephalosporin-resistant Enterobacteriaceae (3GCREB) are an increasing healthcare problem. We aim to describe the 3GCREB infection incidence and compare it to prevalence upon admission. In addition, we aim to describe infections caused by 3GCREB, which are also carbapenem resistant (CRE).MethodsIn 2014-2015, we performed prospective 3GCREB surveillance in clinically relevant patient specimens (screening specimens excluded). Infections counted as hospital-acquired (HAI) when the 3GCREB was detected after the third day following admission, otherwise as community-acquired infection (CAI).ResultsOf 578,420 hospitalized patients under surveillance, 3367 had a 3GCREB infection (0.58%). We observed a similar 3GCREB CAI and HAI incidence (0.28 and 0.31 per 100 patients, respectively). The most frequent pathogen was 3GCR E. coli, in CAI and HAI (0.15 and 0.12 per 100 patients). We observed a CRE CAI incidence of 0.006 and a HAI incidence of 0.008 per 100 patients (0.014 per 1000 patient days).ConclusionsComparing the known 3GCREB admission prevalence of the participating hospitals (9.5%) with the percentage of patients with a 3GCREB infection (0.58%), we conclude the prevalence of 3GCREB in university hospitals to be about 16 times higher than suggested when only patients with 3GCREB infections are considered. Moreover, we find the HAI and CAI incidence caused by CRE in Germany to be relatively low
