Community pharmacy type 2 diabetes risk assessment: demographics and risk results

Objectives: To determine the demographics and risk results of patients accessing a community pharmacy diabetes risk assessment service. Method: Participating patients underwent an assessment using a validated questionnaire to determine their 10-year risk of developing type 2 diabetes. Patients were given appropriate lifestyle advice or referred to their general practitioner if necessary. Key findings: In total, 21 302 risk assessments were performed. Nearly one-third (29%) of 3427 risk assessments analysed yielded a result of moderate or high chance of developing the condition. Conclusions: Community pharmacies can identify a significant number of patients at risk of developing type 2 diabetes in the next 10 years. Further follow-up work needs to be done to determine the cost-effectiveness of such a service and the consequences of receiving a risk assessment

Medication taking in people with hip and knee osteoarthritis: An analysis of the English Longitudinal Study of Ageing

Objectives: Osteoarthritis (OA) is a highly prevalent condition seen across primary care services. Although evidence‐based guidelines have encouraged the prescription of medications, including analgesics, for this population, there remains uncertainty as to which types of individuals actually take prescribed or over‐the‐counter medications. The purpose of the present study was to determine whether there is a difference in characteristics between people who take medicines for OA compared with those who do not. Methods: A cross‐sectional analysis of the English Longitudinal Study of Ageing (ELSA) cohort was undertaken. Individuals who reported hip and/or knee OA pain were included. Data on medication taking were self‐reported and collected as part of the ELSA data collection programme. Logistic regression analyses were undertaken to determine the relationship between potential predictors (demographic, pathology‐specific, psychological, social and functional) and whether individuals took medications for their OA symptoms. Results: A total of 654 participants reported OA: 543 medicine takers and 111 nontakers. Individuals who had access to a car (odds ratio [OR]: 56.2; 95% confidence interval [CI]: 3.35 to 941.36), those with a greater duration of hip pain (OR: 5.79; 95% CI: 1.40 to 24.0) and those who achieved 10 chair raises at greater speed (OR: 1.08; 95% CI: 1.03 to 1.14) were more likely to take OA medicines. Conclusions: The study identified predictors for medication taking in individuals with hip and/or knee OA. Strategies are now warranted to provide better support to these individuals, to improve health and well‐being for this long‐term, disabling condition

The pharmacy care plan service: Service evaluation and estimate of cost-effectiveness

Background: The UK Community Pharmacy Future group developed the Pharmacy Care Plan (PCP) service with a focus on patient activation, goal setting and therapy management.  Objective: To estimate the effectiveness and cost-effectiveness of the PCP service from a health services perspective.  Methods: Patients over 50 years of age prescribed one or more medicines including at least one for cardiovascular disease or diabetes were eligible. Medication review and person-centred consultation resulted in agreed health goals and actions towards achieving them. Clinical, process and cost-effectiveness data were collected at baseline and 12-months between February 2015 and June 2016. Mean differences are reported for clinical and process measures. Costs (NHS) and quality-adjusted life year scores were estimated and compared for 12 months pre- and post-baseline.  Results: Seven hundred patients attended the initial consultation and 54% had a complete set of data obtained. There was a significant improvement in patient activation score (mean difference 5.39; 95% CI 3.9 – 6.9; p<0.001), systolic (mean difference -2.90 mmHg ; 95% CI -4.7 - -1; p=0.002) and diastolic blood pressure (mean difference -1.81 mmHg; 95% CI -2.8 - -0.8; p<0.001), adherence (mean difference 0.26; 95% CI 0.1 – 0.4; p<0.001) and quality of life (mean difference 0.029; 95% CI 0.015 – 0.044; p<0.001). HDL cholesterol reduced significantly and QRisk2 scores increased significantly over the course of the 12 months. The mean incremental cost associated with the intervention was estimated to be £202.91 (95% CI 58.26 to £346.41) and the incremental QALY gain was 0.024 (95% CI 0.014 to 0.034), giving an incremental cost per QALY of £8,495.  Conclusions: Enrolment in the PCP service was generally associated with an improvement over 12 months in key clinical and process metrics. Results also suggest that the service would be cost-effective to the health system even when using worst case assumptions

Development of a hospital Deprescribing Implementation Framework : a focus group study with geriatricians and pharmacists

Background: over 50% of older people in hospital are prescribed a pre-admission medicine that is potentially inappropriate; however, deprescribing by geriatricians and pharmacists is limited. This study aimed to characterise geriatricians’ and pharmacists’ barriers and enablers to deprescribing in hospital. It also intended to develop a framework of intervention components to facilitate implementation of hospital deprescribing. Methods: fifty-four geriatricians and pharmacists representing four UK hospitals attended eight focus groups. We designed a topic guide to invite discussions about barriers and enablers to deprescribing. After thematic analysis, themes were mapped to the theoretical domains framework (TDF), enabling prioritisation of domains for behaviour change. We then identified evidence-based intervention components for changing behaviour within prioritised TDF domains. Results: geriatricians and pharmacists described several deprescribing enablers in the hospital setting including alignment with their role and generalist knowledge, and routine patient monitoring. Five prioritised TDF domains represent the key barriers and enabler: patient and caregiver attachment to medication (social influence); perceptions that deprescribing is riskier than continuing to prescribe (beliefs about consequences); pharmacists’ working patterns limiting capacity to support deprescribing (environmental context and resources); deprescribing being a low hospital priority (goals) and incentives to deprescribe (reinforcement). Prioritised TDF domains aligned with 44 evidence-based intervention components to address the barriers and enabler to hospital deprescribing. Conclusion: the behavioural determinants and their associated intervention components provide a hospital deprescribing implementation framework (hDIF). Intervention components should be selected from the hDIF to provide a theory and evidence-based intervention tailored to hospital contexts

Patient feedback questionnaires to enhance consultation skills of healthcare professionals: a systematic review

Objective: To identify patient feedback questionnaires that assess the development of consultation skills (CSs) of practitioners. Methods: We conducted a systematic search using seven databases from inception to January 2017 to identify self-completed patient feedback questionnaires assessing and enhancing the development of CSs of individual practitioners. Results were checked for eligibility by three authors, and disagreements were resolved by discussion. Reference lists of relevant studies and open grey were searched for additional studies. Results: Of 16,312 studies retrieved, sixteen were included, describing twelve patient feedback questionnaires that were mostly designed for physicians in primary care settings. Most questionnaires had limited data regarding their psychometric properties, except for the Doctor Interpersonal Skills Questionnaire (DISQ). Most studies conducted follow-up, capturing positive views of practitioners regarding the process (n = 14). Feedback was repeated by only three studies, demonstrating different levels of improvement in practitioners’ performance. Conclusion: Identified questionnaires were mainly focused on physicians, however, to support using patient feedback, questionnaires need to be validated with other practitioners. Practice implications: Several patient feedback questionnaires are available, showing potential for supporting practitioners’ development. Valid questionnaires should be used with appropriate practitioners in developing more evidence for the impact they may have on actual consultations

The four or more medicines (FOMM) support service:results from an evaluation of a new community pharmacy service aimed at over-65s

Background: 57% of all prescriptions dispensed in the UK in 2003 were for people aged ≥60, where ≥20% of them were prescribed ≥ five medicines. Inappropriate prescribing and non-adherence have a significant impact on hospital admissions and patient quality of life. The English government has identified that community pharmacy could make a significant contribution to reducing non-adherence and improving the quality of prescribing, reducing both hospital admissions and medicines wastage. Objective: To evaluate a community pharmacy service aimed at patients over the age of 65 years prescribed four or more medicines. Method: Patients were invited to participate in the service by the community pharmacy team. The pharmacist held regular consultations with the patient and discussed risk of falls, pain management, adherence and general health. They also reviewed the patient’s medication using STOPP/START criteria. Data wereas analysed for the first six months of participation in the service. Key findings: 620 patients were recruited with 441 (71.1%) completing the six month study period. Pharmacists made 142 recommendations to prescribers in 110 patients largely centred on potentially inappropriate prescribing of NSAIDs, PPIs or duplication of therapy. At follow-up there was a significant decrease in the total number of falls (mean -0.116 (-0.217 - -0.014)) experienced and a significant increase in medicines adherence (mean difference in MMAS-8: 0.513 (0.337 – 0.689)) and quality of life. Cost per QALY estimates ranged from £11,885 to £32,466 depending on the assumptions made. Conclusion: By focussing on patients over the age of 65 years with four or more medicines, community pharmacists can improve medicines adherence and patient quality of life

Microbial profiling of dental plaque from mechanically ventilated patients

© 2015 The Authors. Micro-organisms isolated from the oral cavity may translocate to the lower airways during mechanical ventilation (MV) leading to ventilator-associated pneumonia (VAP). Changes within the dental plaque microbiome during MV have been documented previously, primarily using culture-based techniques. The aim of this study was to use community profiling by high throughput sequencing to comprehensively analyse suggested microbial changes within dental plaque during MV. Bacterial 16S rDNA gene sequences were obtained from 38 samples of dental plaque sampled from 13 mechanically ventilated patients and sequenced using the Illumina platform. Sequences were processed using Mothur, applying a 97 % gene similarity cut-off for bacterial species level identifications. A significant ‘microbial shift’ occurred in the microbial community of dental plaque during MV for nine out of 13 patients. Following extubation, or removal of the endotracheal tube that facilitates ventilation, sampling revealed a decrease in the relative abundance of potential respiratory pathogens and a compositional change towards a more predominantly (in terms of abundance) oral microbiota including Prevotella spp., and streptococci. The results highlight the need to better understand microbial shifts in the oral microbiome in the development of strategies to reduce VAP, and may have implications for the development of other forms of pneumonia such as community-acquired infection

Mechanism of Hydrogen-Bonded Complex Formation between Ibuprofen and Nanocrystalline Hydroxyapatite.

Nanocrystalline hydroxyapatite (nanoHA) is the main hard component of bone and has the potential to be used to promote osseointegration of implants and to treat bone defects. Here, using active pharmaceutical ingredients (APIs) such as ibuprofen, we report on the prospects of combining nanoHA with biologically active compounds to improve the clinical performance of these treatments. In this study, we designed and investigated the possibility of API attachment to the surface of nanoHA crystals via the formation of a hydrogen-bonded complex. The mechanistic studies of an ibuprofen/nanoHA complex formation have been performed using a holistic approach encompassing spectroscopic (Fourier transform infrared (FTIR) and Raman) and X-ray diffraction techniques, as well as quantum chemistry calculations, while comparing the behavior of the ibuprofen/nanoHA complex with that of a physical mixture of the two components. Whereas ibuprofen exists in dimeric form both in solid and liquid state, our study showed that the formation of the ibuprofen/nanoHA complex most likely occurs via the dissociation of the ibuprofen dimer into monomeric species promoted by ethanol, with subsequent attachment of a monomer to the HA surface. An adsorption mode for this process is proposed; this includes hydrogen bonding of the hydroxyl group of ibuprofen to the hydroxyl group of the apatite, together with the interaction of the ibuprofen carbonyl group to an HA Ca center. Overall, this mechanistic study provides new insights into the molecular interactions between APIs and the surfaces of bioactive inorganic solids and sheds light on the relationship between the noncovalent bonding and drug release properties

Mapping of modifiable barriers and facilitators of medication adherence in bipolar disorder to the Theoretical Domains Framework: a systematic review protocol

Introduction: People with bipolar disorder require long-term treatment but it is estimated that 40% of these people do not adhere to prescribed medication regimens. Non-adherence increases the risk of relapse, hospitalisation and suicide. Some evidence syntheses report barriers to mental health treatment adherence but rarely delineate between modifiable and non-modifiable barriers. They also fail to distinguish between the patients’ perspective and that of other stakeholders such as clinicians despite of their different understanding and priorities about adherence. Facilitators of adherence, which are also important for informing adherence intervention design, are also lacking from syntheses and few syntheses focus on medications for bipolar disorder. This systematic review aims to identify modifiable barriers and facilitators (determinants) of medication adherence in bipolar disorder. We also plan to report determinants of medication adherence from perspectives of patients, carers, healthcare professionals and other third parties. A unique feature of this systematic review in the context of mental health is the use of the Theoretical Domains Framework (TDF) to organise the literature identified determinants of medication adherence. Methods and analysis: The protocol adheres to Preferred Reporting Items for Systematic Reviews and Meta-Analyses Protocols and ENhancing Transparency in REporting the synthesis of Qualitative research (ENTREQ) guidelines. This review will include both qualitative and quantitative primary studies exploring determinants of medication adherence in bipolar disorder. We will search the following databases using a preplanned strategy: CINAHL, Cochrane Library (CENTRAL), Embase, LiLACS, Medline, PsychINFO, PubMed without date restrictions. We will report the quality of included studies. We will use framework synthesis using the TDF as an a priori ‘framework’. We will map the literature identified modifiable determinants to the domains of TDF. Ethics and dissemination: Ethical approval is not required as primary data will not be collected. The results will be disseminated through a peer-reviewed publication. PROSPERO registration number:CRD42018096306

Recent Results from Epitaxial Growth on Step Free 4H-SiC Mesas

This paper updates recent progress made in growth, characterization, and understanding of high quality homoepitaxial and heteroepitaxial films grown on step-free 4H-SiC mesas. First, we report initial achievement of step-free 4H-SiC surfaces with carbon-face surface polarity. Next, we will describe further observations of how step-free 4H-SiC thin lateral cantilever evolution is significantly impacted by crystal faceting behavior that imposes non-uniform film thickness on cantilever undersides. Finally, recent investigations of in-plane lattice constant mismatch strain relief mechanisms observed for heteroepitaxial growth of 3C-SiC as well as 2H-AlN/GaN heterofilms on step-free 4H-SiC mesas will be reviewed. In both cases, the complete elimination of atomic heterointerface steps on the mesa structure enables uniquely well-ordered misfit dislocation arrays to form near the heterointerfaces with remarkable lack of dislocations threading vertically into the heteroepilayers. In the case of 3C-SiC heterofilms, it has been proposed that dislocation half-loops nucleate at mesa edges and glide laterally along the step-free 3C/4H interfaces. In contrast, 3C-SiC and 2H-AlN/GaN heterofilms grown on 4H-SiC mesas with steps exhibit highly disordered interface misfit dislocation structure coupled with 100X greater density of dislocations threading through the thickness of the heteroepilayers. These results indicate that the presence of steps at the heteroepitaxial interface (i.e., on the initial heteroepitaxial nucleation surface) plays a highly important role in the defect structure, quality, and relaxation mechanisms of single-crystal heteroepitaxial films
