The issue of up-to-dateness when conducting overviews seems to be neglected by most authors of overviews. Authors should assess the quality of evidence, based on their included reviews first.

BackgroundOral medication for patients with type 2 diabetes mellitus plays an important role in diabetes care and is associated with a high level self-care behavior and self-management. However, poor adherence to diabetes treatment is common which causes severe health complications and increased mortality. Barriers to adherence may consist of complex treatment regimens often along with long-term multi-therapies, side effects due to the medication as well as insufficient, incomprehensible or confusing information or instructions provided by the health care provider. Multidisciplinary approaches can support adherence success and can enable a more effective management of diabetes care. One approach in diabetes care can be the involvement of a pharmacist. The aim was to analyze the effectiveness of adherence-enhancing pharmacist interventions for oral medication in type 2 diabetes mellitus.MethodsA systematic review of randomized controlled trials. The study quality was assessed with the Cochrane risk of bias tool.ResultsOf 491 hits, six publications were included. Two studies mainly examining educational interventions showed a significant improvement in adherence. Moreover, the quality of the included studies was deficient.ConclusionAlthough pharmacist interventions might potentially improve adherence to type 2 diabetes mellitus medication, high-quality studies are needed to assess effectiveness.

PurposeTo investigate accident casualties’ long-term subjective evaluation of treatment outcome 6 weeks and 12 months after discharge and its relation to the experienced surgeon’s empathy during hospital treatment after trauma in consideration of patient-, injury-, and health-related factors. The long-term results are compared to the 6-week follow-up outcomes.Patients and methodsTwo hundred and seventeen surgery patients were surveyed at 6 weeks, and 206 patients at 12 months after discharge from the trauma surgical general ward. The subjective evaluation of medical treatment outcome was measured 6 weeks and 12 months after discharge with the respective scale from the Cologne Patient Questionnaire. Physician Empathy was assessed with the Consultation and Relational Empathy Measure. The correlation between physician empathy and control variables with the subjective evaluation of medical treatment outcome 12 months after discharge was identified by means of logistic regression analysis under control of sociodemographic and injury-related factors.ResultsOne hundred and thirty-six patients were included within the logistic regression analysis at the 12-month follow-up. Compared to the 6-week follow-up, the level of subjective evaluation of medical treatment outcome was slightly lower and the association with physician empathy was weaker. Compared to patients who rated the empathy of their surgeon lower than 31 points, patients with ratings of 41 points or higher had a 4.2-fold higher probability to be in the group with a better medical treatment outcome (3.5 and above) on the Cologne Patient Questionnaire scale 12 months after discharge from hospital (P=0.009, R2=33.5, 95% confidence interval: 1.440–12.629).ConclusionPhysician empathy is the strongest predictor for a higher level of trauma patients’ subjective evaluation of treatment outcome 6 weeks and 12 months after discharge from the hospital. Interpersonal factors between surgeons and their patients are possible key levers for improving patient outcomes in an advanced health system. Communication trainings for surgeons might prepare them to react appropriately to their patients’ needs and lead to satisfactory outcomes for both parties.

Although the interest in overviews is rising, little methodological guidance for the conduct of overviews is provided by HTA agencies. Overviews are of special interest in the context of rapid assessments to support policy-making within a short time frame. Therefore, empirical work on overviews needs to be extended. National strategies and experience should be disclosed and discussed.

BackgroundAdherence is a crucial point for the successful treatment of a hepatitis-C virus infection. Studies have shown that especially adherence to ribavirin is important.The objective of this systematic review was to identify factors that influence adherence in hepatitis-C infected patients taking regimes that containing ribavirin.MethodsA systematic literature search was performed in Medline and Embase in March 2014 without limits for publication date. Titles and abstracts and in case of relevance, full-texts were screened according to predefined inclusion criteria. The risk of bias was assessed. Both process steps were carried out independently by two reviewers. Relevant data on study characteristics and results were extracted in standardized tables by one reviewer and checked by a second. Data were synthesized in a narrative way using a standardized procedure.ResultsNine relevant studies were identified. The number of analyzed patients ranged between 12 and 5706 patients. The study quality was moderate. Especially the risk of bias regarding the measurement of influencing factors was mostly unclear.“Psychiatric disorders” (N = 5) and having to take “higher doses of ribavirin” (N = 3) showed a negative influence on adherence. In contrast, a “HIV co-infection” (N = 2) and the “hemoglobin level” (N = 2) were associated with a positive influence on adherence. Furthermore, there is the tendency that male patients are more adherent than female patients (N = 6). “Alcohol consumption” (N = 2), “education”, “employment status”, “ethnic group“,”hepatitis-C virus RNA” (N = 4), “genotype” (N = 5), “metavir activity” (N = 1) and “weight” (N = 3) showed mostly no effect on adherence. Although, some studies showed statistically significant results for “age”, “drug use” , “genotype”, “medication dose interferon“, and “treatment experience” the effect is unclear because effect directions were partly conflicting.The other factors were heterogeneous regarding the effect direction and/or statistical significance.ConclusionThere are some factors that seem to show an influence on adherence. However, due to the heterogeneity (e.g. patient characteristics, regimes, settings, countries) no general conclusions can be made. The results should rather be considered as indications for factors that can have an influence on adherence in hepatitis-C infected patients taking regimes that containing ribavirin.
