Formation of extraterrestrial peptides and their derivatives.

The formation of protein precursors, due to the condensation of atomic carbon under the low-temperature conditions of the molecular phases of the interstellar medium, opens alternative pathways for the origin of life. We perform peptide synthesis under conditions prevailing in space and provide a comprehensive analytic characterization of its products. The application of 13C allowed us to confirm the suggested pathway of peptide formation that proceeds due to the polymerization of aminoketene molecules that are formed in the C + CO + NH3 reaction. Here, we address the question of how the efficiency of peptide production is modified by the presence of water molecules. We demonstrate that although water slightly reduces the efficiency of polymerization of aminoketene, it does not prevent the formation of peptides.

A tailored programme to implement recommendations for multimorbid patients with polypharmacy in primary care practices-process evaluation of a cluster randomized trial.

BACKGROUND: We developed and evaluated a tailored programme to implement three evidence-based recommendations for multimorbid patients with polypharmacy into primary care practices: structured medication counselling including brown bag reviews, the use of medication lists and medication reviews. No effect on the primary outcome was found. This process evaluation aimed to identify factors associated with outcomes by exploring nine hypotheses specified in the logic model of the tailored programme. METHODS: The tailored programme was developed with respect to identified determinants of practice and consisted of a workshop for practice teams, elaboration of implementation action plans, aids for medication reviews, a multilingual info-tool for patients on a tablet PC, posters and brown paper bags as reminders for patients. The tailored programme was evaluated in a cluster randomized trial. The process evaluation was based on various data sources: interviews with general practitioners and medical assistants of the intervention group and a survey with general practitioners of the intervention and control group, written reports on the implementation action plans, documentation forms for structured medication counselling and the log file of the info-tool. RESULTS: We analyzed 12 interviews, 21 questionnaires, 120 documentation forms for medication counselling, 5 implementation action plans and one log file of the info-tool. The most frequently reported effect of the tailored programme was the increase of awareness for the health problem and the recommendations, while implementation of routine processes was only reported for structured medication counselling. The survey largely confirmed the usefulness of the applied strategies, yet the interviews provided a more detailed understanding of the actual use of the strategies and several suggestions for modifications of the tailored programme. CONCLUSIONS: The tailored programme seemed to have induced awareness as a first step of behaviour change. Several modifications of the tailored programme may enhance its effectiveness such as conducting outreach visits instead of a workshop, improved targeting, provision of evidence, integration of tools into the practice software and information materials in tailored formats. TRIAL REGISTRATION: This study is linked to an outcome evaluation study with the registration ISRCTN34664024 , assigned 14/08/2013.

Impact of a tailored program on the implementation of evidence-based recommendations for multimorbid patients with polypharmacy in primary care practices-results of a cluster-randomized controlled trial.

BACKGROUND: Multimorbid patients receiving polypharmacy represent a growing population at high risk for negative health outcomes. Tailoring is an approach of systematic intervention development taking account of previously identified determinants of practice. The aim of this study was to assess the effect of a tailored program to improve the implementation of three important processes of care for this patient group: (a) structured medication counseling including brown bag reviews, (b) the use of medication lists, and (c) structured medication reviews to reduce potentially inappropriate medication. METHODS: We conducted a cluster-randomized controlled trial with a follow-up time of 9 months. Participants were general practitioners (GPs) organized in quality circles and participating in a GP-centered care contract of a German health insurance. Patients aged >50 years, suffering from at least 3 chronic diseases, receiving more than 4 drugs, and being at high risk for medication-related events according to the assessment of the treating GP were enrolled. The tailored program consisted of a workshop for GPs and health care assistants, educational materials and reminders for patients, and the elaboration of implementation action plans. The primary outcome was the change in the degree of implementation between baseline and follow-up, measured by a summary score of 10 indicators. The indicators were based on structured surveys with patients and GPs. RESULTS: We analyzed the data of 21 GPs (10 - intervention group, 11 - control group) and 273 patients (130 - intervention group, 143 - control group). The increase in the degree of implementation was 4.2 percentage points (95% confidence interval: -0.3, 8.6) higher in the intervention group compared to the control group (p = 0.1). Two of the 10 indicators were significantly improved in the intervention group: medication counseling (p = 0.017) and brown bag review (p = 0.012). Secondary outcomes showed an effect on patients' self-reported use of medication lists when buying drugs in the pharmacy (p = 0.03). CONCLUSIONS: The tailored program may improve implementation of medication counseling and brown bag review whereas the use of medication lists and medication reviews did not improve. No effect of the tailored program on the combined primary outcome could be substantiated. Due to limitations of the study, results have to be interpreted carefully. The factors facilitating and hindering successful implementation will be examined in a comprehensive process evaluation. TRIAL REGISTRATION NUMBER: ISRCTN34664024 , assigned 14/08/2013.

Medication Lists and Brown Bag Reviews: Potential Positive and Negative Impacts on Patients Beliefs about Their Medicine.

INTRODUCTION: Medication lists and structured medication counselling (SMC) including "brown bag reviews" (BBR) are important instruments for medication safety. The aim of this study was to explore whether patients' use of a medication list is associated with their beliefs about their medicine and their memory of SMC. METHODS: Baseline data of 344 patients enrolled into the "Polypharmacy in Multimorbid Patients study" were analysed. Linear regression models were calculated for the "specific necessity subscale" (SNS) and the "specific concerns subscale" (SCS) of the German "Beliefs About Medicine Questionnaire," including self-developed variables assessing patients' use of a medication list, their memory of SMC, and sociodemographic data. RESULTS: 62.8% (n = 216) remembered an appointment for SMC and 32.0% (n = 110) BBR. The SNS correlated positively with regular receipt of a medication list (ß = 0.286, p < 0.01) and negatively with memory of a BBR (ß = -0.268; p < 0.01). The SCS correlated positively with memory of a BBR (ß = 0.160, p = 0.02) and negatively with the comprehensiveness of the mediation list (ß = -0.224; p < 0.01). CONCLUSIONS: A comprehensive medication list may reduce patients' concerns and increase the perceived necessity of their medication. A potential negative impact of BBR on patients' beliefs about their medicine should be considered and quality standards for SMC developed.

Design and delivery of a tailored intervention to implement recommendations for multimorbid patients receiving polypharmacy into primary care practices.

Introduction. Managing polypharmacy is particularly demanding for general practitioners as coordinators of care. Recently, a German guideline for polypharmacy in primary care has been published. This paper describes the content and delivery of a tailored intervention, which aims at improving the implementation of guideline recommendations for polypharmacy into practice, considering individual barriers. Materials and Methods. Firstly, barriers for implementation and the corresponding strategies to address them have been identified. On this basis, an intervention consisting of a workshop for health care professionals and educational materials for patients has been developed. The workshop focused on knowledge, awareness, and skills. The educational materials included a tablet computer. Practice teams will elaborate individual concepts of how to implement the recommendations into their practice. The workshop has been evaluated by the participants by means of a questionnaire. Results. During the workshop 41 possible sources of medication errors and 41 strategies to improve medication management have been identified. Participants evaluated the workshop overall positively, certifying its relevancy to practice. Discussion. The concept of the workshop seemed appropriate to impart knowledge about medication management to the participants. It will have to be evaluated, if the intervention finally resulted in an improved implementation of the guideline recommendations.

[Developing a tailored intervention: implementing recommendations for polypharmacy in multimorbid patients (PomP)]. / Entwicklung einer maßgeschneiderten Intervention (Tailoring) am Beispiel der Implementierung von Empfehlungen zur Polypharmakotherapie bei multimorbiden Patienten (PomP).

INTRODUCTION: Implementation research deals with the question of how to ensure that evidence-based knowledge is put into practice. One approach is the development of "tailored interventions (TI)". These are designed to address previously identified barriers and enablers. A common definition or methodological concept for TI has not yet been established. In this paper, a concept for TI is introduced. We describe the stepwise development of an implementation intervention for GP settings where recommendations based on current evidence are provided for the treatment of multimorbid patients receiving polypharmacy. Each step will be explained and illustrated by original data. METHODS/RESULTS: A stepwise approach was used to develop a TI: problem analysis, identification and prioritisation of determinants, identification and prioritisation of strategies and the design of a complex intervention and its underlying logic model. DISCUSSION: The stepwise exemplary description of this tailoring strategy may support other researchers in this field when designing a TI.

A tailored implementation intervention to implement recommendations addressing polypharmacy in multimorbid patients: study protocol of a cluster randomized controlled trial.

BACKGROUND: Multimorbid patients frequently receive complex medication regimens and are at higher risk for adverse drug reactions and hospitalisations. Managing patients with polypharmacy is demanding, because it requires coordination of multiple prescribers and intensive monitoring. Three evidence-based recommendations addressing polypharmacy in primary care are structured medication counselling, use of medication lists and medication reviews to avoid potentially inappropriate medication (PIM). Although promising to improve patient outcomes, these recommendations are not well implemented in German routine care. Implementation of guidelines is often hindered by specific "determinants of change". "Tailored" interventions are designed to specifically address previously identified determinants. This study examines a tailored intervention to implement the aforementioned recommendations into German primary care practices. This study is part of the European Tailored Interventions for Chronic Diseases project, which aims at contributing knowledge about the methods used for tailoring. METHODS/DESIGN: The study is designed as a cluster randomized controlled trial with primary care practices of general practitioners (GPs) who are organized in quality circles. Quality circles will be the unit of randomization with a 1:1 ratio. Follow-up time is 6 months. GPs and healthcare assistants in the intervention group will receive training on medication management. Each GP will create a tailored concept of how to implement the three recommendations into his/her practice. Evidence-based checklists for medication counselling and medication reviews will be provided for physicians. A tablet PC with an interactive educational tool and information leaflets will be provided for use by patients to inform about the necessity of continuous medication management. Control practices will not receive special training and will provide care as usual. Primary outcome is the degree of implementation of the three recommendations, which will be measured using a prespecified set of indicators. Additionally, the PIM prescription rate, patient activation, patients' beliefs about medicine, medication adherence and patients' social support will be measured. DISCUSSION: This study will contribute knowledge about the feasibility of implementing recommendations for managing patients with polypharmacy in primary care practices. Additionally, this study will contribute knowledge about methods for tailoring of implementation interventions. TRIAL REGISTRATION: Clinicaltrials.gov ISRCTN34664024.
