Factors, Perceptions and Beliefs Associated with Inappropriate Antibiotic Prescribing in German Primary Dental Care: A Qualitative Study.

Dentists account for up to 10% of all prescribed antibiotics in primary care, with up to 80% being inappropriate. Targeted approaches to change prescription behavior are scarce. This study aimed at identifying specific barriers and facilitators for prudent antibiotic use in German dentistry by using qualitative methods. Nine in-depth interviews and two focus group discussions with another nine dentists were conducted and analyzed thematically. Dentists described being conflicted by the discordance of available treatment time and the necessity of thorough therapy. Lacking the opportunity of follow-up led to uncertainty. Dentists felt a lack of medical competency concerning prophylaxis for infectious endocarditis. A lack of empowerment to make therapeutic decisions interfered with guideline-conformity. The communication with fellow physicians is conflictual and improvement was wished for. In consequence, dentists felt pressure by potential medico-legal liability. Patients demanding quick and easy pain relief put extra strain on the interviewed dentists. Our hypotheses concord with preliminary data, mainly from the UK, but highlighted specifically medico-legal concerns and interprofessional communication as even greater barriers as described before. Tailored interventional concepts based on our findings may have the potential to lower antibiotic prescriptions in German primary dental care.

[Does place of residence have an influence on shared decision making for patients with type 2 diabetes in general practice?] / Beeinflusst der Wohnort die gemeinsame Entscheidungsfindung in der Hausarztpraxis bei Patienten mit Diabetes mellitus Typ 2?

OBJECTIVE: In the last 20 years, patient involvement in clinical decision-making has continuously gained traction in scientific and clinical (including general practice, GP) discussions. Patients with chronic conditions in particular may benefit from active involvement. Referring to existing studies on shared decision making and regional differences; patients with poorly controlled diabetes mellitus type 2 (DM2) were used as an example to investigate the perceived involvement during clinical decision making in general practice. Differences in treatment options based on the patients' place of residence (East- and West Germany) were compared. METHODS: 501 West- (North-Rhine-Westphalia, NRW) and 338 East-German (Mecklenburg-Western Pomerania, MWP) patients with DM2 and HbA1c levels≥8.0 were assessed during the cluster-randomised controlled trial DEBATE, which was conducted between 2011 and 2012. The questionnaire to measure participatory decision making (Q-PDM) was used in order to provide an estimate of their involvement in clinical decision making processes, and baseline data was analysed before intervention. The standardised Q-PDM summed value was compared among the different subgroups (i. e., place of residence, age, sex) using bivariate group analyses (t tests), and a multivariate regression analysis was conducted. RESULTS: Patients living in the MWP region perceived a higher level of involvement in GP decision making than NRW residents. Younger patients with DM2 showed higher Q-PDM summed values than older patients. When all variables, including 'GP practice' (number of patients per GP/cluster), were considered together in the multivariate regression analysis, the place of residence would no longer show an independent effect on perceived decision making. The expected difference between MWP and NRW (i. e. East/West Germany) could not be confirmed, while a significant difference remained with regard to age. Education, population density, sex and marital status did not show any relevant differences. CONCLUSION: Patient age remains an important factor influencing the perceived involvement in joint decision making and should be taken into account while implementing clinical decision making processes in the future. It is possible that patients of different age and with different chronic diseases may need different decision support offerings (e. g., educational videos, booklets or computer-based decision aids). Trainings in communication skills or in the implementation of patient-centred communication might be effective on the GP level to reduce possible barriers to shared decision making.

Reduction of antibiotic prescriptions for acute respiratory tract infections in primary care: a systematic review.

BACKGROUND: Although most respiratory tract infections (RTIs) are due to viral infections, they cause the majority of antibiotic (Abx) prescriptions in primary care. This systematic review summarises the evidence on the effectiveness of interventions in primary care aiming to reduce Abx prescriptions in patients ≥ 13 years for acute RTI. METHODS: We searched the databases "MEDLINE/PubMed" and "Cochrane Library" for the period from January 1, 2005, to August 31, 2016, for randomised controlled trials (RCTs) in primary care aiming at the reduction of Abx prescriptions for patients suffering from RTI. Out of 690 search results, 67 publications were retrieved and 17 RCTs were included. We assumed an absolute change of 10% as minimal important change. RESULTS: Twelve out of 17 included RCTs showed statistically significant lower Abx prescription rates in the intervention groups, but only six of them reported a clinically relevant reduction according to our definition. Communication skills training (CST) and point-of-care testing (POCT) were the most effective interventions. Pre-intervention Abx prescription rates varied between 13.5% and 80% and observed reductions ranged from 1.5 to 23.3%. Studies with post-intervention rates lower than 20% had no significant effects. Post-intervention observation periods ranged from 2 weeks up to 3.5 years. The design of the trials was heterogeneous precluding calculation of pooled effect size. The reporting of many RCTs was poor. CONCLUSIONS: CST and POCT alone or as adjunct can reduce antibiotic prescriptions for RTI. Eleven out of 17 trials were not successfully reducing Abx prescription rates according to our definition of minimal important change. However, five of them reported a statistically significant reduction. Trials with initially lower prescription rates were less likely to be successful. Future trials should investigate sustainability of intervention effects for a longer time period. The generalisability of findings was limited due to heterogeneous designs and outcome measures. Therefore, a consensus of designing and reporting of studies aiming at reducing antibiotic prescriptions is urgently needed to generate meaningful evidence.

In vitro chlorhexidine release from alginate based microbeads for periodontal therapy.

Periodontitis is one of the most common infectious diseases globally that, if untreated, leads to destruction of the tooth supporting tissues and finally results in tooth loss. Evidence shows that standard procedures as mechanical root cleaning could be supported by further treatment options such as locally applied substances. Due to gingival crevicular fluid flow, substances are commonly washed out off the periodontal pockets. The evaluation of administration techniques and the development of local drug releasing devices is thus an important aspect in periodontal research. This study describes the development and examination of a new alginate based, biodegradable and easily applicable drug delivery system for chlorhexidine (CHX). Different micro beads were produced and loaded with CHX and the release profiles were investigated by high performance liquid chromatography (HPLC). The in vitro-demonstrated release of CHX from alginate based beads shows comparable releasing characteristics as clinically approved systems. Yet many characteristics of this new delivery system show to be favourable for periodontal therapy. Easy application by injection, low production costs and multifunctional adaptions to patient related specifics may improve the usage in routine care.

[Approaches of general practitioners and patients to multimorbidity. Qualitative study]. / Multimorbidität aus Hausarzt- und Patientensicht. Qualitative Studie.

BACKGROUND: For general practioners (GP) the treatment of patients suffering from multimorbidity is an everyday challenge. For these patients guidelines which each focus on a specific chronic disease cannot be applied comprehensively and equally; therefore, it is necessary to prioritize. OBJECTIVE: Given this situation the study aimed at analyzing how GPs and patients deal with this challenge and what their priorities are. MATERIAL AND METHODS: Narrative interviews were conducted with 9 GPs and 19 of their multimorbid patients. The data were analyzed by means of content analysis. RESULTS: The majority of interviewed patients felt well or very well cared for by their GPs; however, GPs and multimorbid patients often had relatively different priorities. Whereas GPs mostly focused on the management of diseases that could lead to life-threatening situations, patients put an emphasis on maintaining autonomy and a social life. CONCLUSION: The results of this study suggest that there is room for development in the way GPs and multimorbid patients communicate with each other, particularly as far as shared priority setting is concerned.

Dental care resistance prevention and antibiotic prescribing modification-the cluster-randomised controlled DREAM trial.

BACKGROUND: Bacterial resistance development is one of the most urgent problems in healthcare worldwide. In Europe, dentistry accounts for a comparatively high amount of antibiotic prescriptions. In light of increasing levels of bacterial resistance, this development is alarming. So far, very few interventional studies have been performed, and further research is urgently needed. By means of a complex educational intervention, the DREAM trial aims at optimising antibiotic prescribing behaviour of general dentists in Germany. METHOD: This is a cluster-randomised controlled trial, where each cluster consists of one dental practice and all of its patients in a defined period. Participants are general dentists practicing in the German region of Mecklenburg-Western Pomerania. Randomisation takes place after baseline data collection (6 months) and will be stratified by the antibiotic prescribing rates of the participating dental practices. Dentists randomised into the intervention group will participate in a complex small group educational seminar that aims at: increasing knowledge on bacterial resistance, pharmacology, and prophylaxis of infectious endocarditis; increasing awareness of dentist-patient communication using video-taped vignettes of dentist-patient communication on antibiotic treatment; improving collaboration between general dentists, general practitioners, and practice-based cardiologists on the necessity of antibiotic prophylaxis; enhancing awareness of the dentists' own prescribing habits by providing antibiotic prescribing feedback; and increasing patient knowledge on antibiotic treatment by providing patient-centred information material on antibiotic prophylaxis of endocarditis. The dentists randomised into the control group will not receive any educational programme and provide care as usual. Primary outcome is the overall antibiotic prescribing rate measured at T1 (period of six months after intervention). In a subgroup of adult patients affected by odontogenic infections, microbiological analyses for antibiotic resistance of oral streptococci are performed. DISCUSSION: Major aim of the study is to improve the process of decision making with regard to antibiotic prescribing. The approach is simple to implement and might be used rapidly in graduate and post-graduate medical education. We expect the results of this trial to have a major impact on antibiotic prescription strategies and practices in Germany. TRIAL REGISTRATION: Current Controlled Trials ISRCTN09576376.
