Effects of the Million Hearts Model on Myocardial Infarctions, Strokes, and Medicare Spending: A Randomized Clinical Trial.

Importance: The Million Hearts Model paid health care organizations to assess and reduce cardiovascular disease (CVD) risk. Model effects on long-term outcomes are unknown. Objective: To estimate model effects on first-time myocardial infarctions (MIs) and strokes and Medicare spending over a period up to 5 years. Design, Setting, and Participants: This pragmatic cluster-randomized trial ran from 2017 to 2021, with organizations assigned to a model intervention group or standard care control group. Randomized organizations included 516 US-based primary care and specialty practices, health centers, and hospital-based outpatient clinics participating voluntarily. Of these organizations, 342 entered patients into the study population, which included Medicare fee-for-service beneficiaries aged 40 to 79 years with no previous MI or stroke and with high or medium CVD risk (a 10-year predicted probability of MI or stroke [ie, CVD risk score] ≥15%) in 2017-2018. Intervention: Organizations agreed to perform guideline-concordant care, including routine CVD risk assessment and cardiovascular care management for high-risk patients. The Centers for Medicare & Medicaid Services paid organizations to calculate CVD risk scores for Medicare fee-for-service beneficiaries. CMS further rewarded organizations for reducing risk among high-risk beneficiaries (CVD risk score ≥30%). Main Outcomes and Measures: Outcomes included first-time CVD events (MIs, strokes, and transient ischemic attacks) identified in Medicare claims, combined first-time CVD events from claims and CVD deaths (coronary heart disease or cerebrovascular disease deaths) identified using the National Death Index, and Medicare Parts A and B spending for CVD events and overall. Outcomes were measured through 2021. Results: High- and medium-risk model intervention beneficiaries (n = 130 578) and standard care control beneficiaries (n = 88 286) were similar in age (median age, 72-73 y), sex (58%-59% men), race (7%-8% Black), and baseline CVD risk score (median, 24%). The probability of a first-time CVD event within 5 years was 0.3 percentage points lower for intervention beneficiaries than control beneficiaries (3.3% relative effect; adjusted hazard ratio [HR], 0.97 [90% CI, 0.93-1.00]; P = .09). The 5-year probability of combined first-time CVD events and CVD deaths was 0.4 percentage points lower in the intervention group (4.2% relative effect; HR, 0.96 [90% CI, 0.93-0.99]; P = .02). Medicare spending for CVD events was similar between the groups (effect estimate, -$1.83 per beneficiary per month [90% CI, -$3.97 to -$0.30]; P = .16), as was overall Medicare spending including model payments (effect estimate, $2.11 per beneficiary per month [90% CI, -$16.66 to $20.89]; P = .85). Conclusions and Relevance: The Million Hearts Model, which encouraged and paid for CVD risk assessment and reduction, reduced first-time MIs and strokes. Results support guidelines to use risk scores for CVD primary prevention. Trial Registration: ClinicalTrials.gov Identifier: NCT04047147.

Efficient Qubit Measurement with a Nonreciprocal Microwave Amplifier.

The act of observing a quantum object fundamentally perturbs its state, resulting in a random walk toward an eigenstate of the measurement operator. Ideally, the measurement is responsible for all dephasing of the quantum state. In practice, imperfections in the measurement apparatus limit or corrupt the flow of information required for quantum feedback protocols, an effect quantified by the measurement efficiency. Here, we demonstrate the efficient measurement of a superconducting qubit using a nonreciprocal parametric amplifier to directly monitor the microwave field of a readout cavity. By mitigating the losses between the cavity and the amplifier, we achieve a measurement efficiency of (72±4)%. The directionality of the amplifier protects the readout cavity and qubit from excess backaction caused by amplified vacuum fluctuations. In addition to providing tools for further improving the fidelity of strong projective measurement, this work creates a test bed for the experimental study of ideal weak measurements, and it opens the way toward quantum feedback protocols based on weak measurement such as state stabilization or error correction.

Return to work a bumpy road: a qualitative study on experiences of work ability and work situation in individuals with chronic whiplash-associated disorders.

BACKGROUND: Work resumption is a big challenge in the rehabilitation process for individuals with whiplash-associated disorders (WAD). To better meet the needs of individuals with WAD in their return to work process, more knowledge on their experiences and perspectives is needed. The aim of this study was to explore the experiences of work ability and the work situation of individuals who participated in a neck-specific exercise programme for chronic WAD. METHODS: This qualitative study has an exploratory and descriptive design based on data collected through open-ended interviews with 17 individuals with chronic WAD. Data were analysed inductively using conventional content analysis. RESULTS: Analysis of the data yielded the following five categories related to the participants' narratives on their experiences of work ability and their work situation: Return to work - a process of setbacks and bureaucracy; The need to be understood by health care professionals, and to receive a treatment plan; Individual resources are important for work ability; The consequences of reduced work ability; and Working conditions are important for work ability. CONCLUSION: Individuals with chronic WAD often struggle to return to work. Emotional and practical support from stakeholders is imperative and needs to be strengthened. Participating in a neck-specific exercise programme, including being acknowledged and receiving information about WAD, could positively affect the work ability of WAD sufferers. This study has provided management strategies to improve the ability to work for individuals with chronic WAD, and highlights the need to incorporate a healthy and sustainable return to work in the rehabilitation of individuals with WAD, thereby making their return to work a success.

Ultrastrong Parametric Coupling between a Superconducting Cavity and a Mechanical Resonator.

We present a new optomechanical device where the motion of a micromechanical membrane couples to a microwave resonance of a three-dimensional superconducting cavity. With this architecture, we realize ultrastrong parametric coupling, where the coupling not only exceeds the dissipation in the system but also rivals the mechanical frequency itself. In this regime, the optomechanical interaction induces a frequency splitting between the hybridized normal modes that reaches 88% of the bare mechanical frequency, limited by the fundamental parametric instability. The coupling also exceeds the mechanical thermal decoherence rate, enabling new applications in ultrafast quantum state transfer and entanglement generation.

The Impact of a Health Information Technology-Focused Patient-centered Medical Neighborhood Program Among Medicare Beneficiaries in Primary Care Practices: The Effect on Patient Outcomes and Spending.

BACKGROUND: The Center for Medicare & Medicaid Innovation (CMMI) tests new models of paying for or delivering health care services and expands models that improve health outcomes while lowering medical spending. CMMI gave TransforMED, a national learning and dissemination contractor, a 3-year Health Care Innovation Award (HCIA) to integrate health information technology systems into physician practices. This paper estimates impacts of TransforMED's HCIA-funded program on patient outcomes and Medicare parts A and B spending. RESEARCH DESIGN: We compared outcomes for Medicare fee-for-service (FFS) beneficiaries served by 87 treatment practices to outcomes for Medicare FFS beneficiaries served by 286 matched comparison practices, adjusting for differences in outcomes between the 2 groups during a 1-year baseline period. We estimated impacts in 3 evaluation outcome domains: quality-of-care processes, service use, and spending. RESULTS: We estimated the program led to a 7.1% reduction in inpatient admissions and a 5.7% decrease in the outpatient emergency department visits. However, there was no evidence of statistically significant effects in outcomes in either the quality-of-care processes or spending domains. CONCLUSIONS: These results indicate that TransforMED's program reduced service use for Medicare FFS beneficiaries, but also show that the program did not have statistically significant favorable impacts in the quality-of-care processes or spending domains. These results suggest that providing practices with population health management and cost-reporting software-along with technical assistance for how to use them-can complement practices' own patient-centered medical home transformation efforts and add meaningfully to their impacts on service use.

We have had a gutful: The need for deprescribing proton pump inhibitors.

WHAT IS KNOWN AND OBJECTIVE: Proton pump inhibitor (PPI) prescribing may often be inappropriate and expose patients to a risk of adverse effects, while incurring unnecessary healthcare expenditure. Our objective was to determine PPI usage in Australia since 2002 and review international studies investigating inappropriate PPI prescribing, including those that discussed interventions to address this issue. METHODS: Australian Pharmaceutical Benefits Scheme (PBS) and Repatriation Pharmaceutical Benefits Scheme (RPBS) data were analysed. A narrative literature review relevant to the objective was conducted. Time series analysis was also used to examine the trend of reported PPI appropriate use across the international studies included in this review. RESULTS AND DISCUSSION: Proton pump inhibitor use in Australia increased between 2002 and 2010 and then gradually decreased. Estimates of the extent of inappropriate use in the international literature had a wide variation (11-84%). There appeared to be little change in the extent of appropriate PPI use reported through 34 international studies from 2000 to 2016. Interventions to address inappropriate use included patient-centred deprescribing, academic detailing, educational programmes and drug safety notifications. WHAT IS NEW AND CONCLUSION: Proton pump inhibitors continue to be overused worldwide and should be a focus for deprescribing programmes. Ongoing education and awareness campaigns for health professionals and patients, including electronic reminders at the point of prescribing, are strategies that have potential to reduce PPI use in individuals who do not have an evidence-based clinical indication for their long-term use.

Impetigo: A need for new therapies in a world of increasing antimicrobial resistance.

WHAT IS KNOWN AND OBJECTIVE: Impetigo is a highly contagious bacterial skin infection and is one of the most common skin infections in children. Antibiotics are the first-line treatment when multiple lesions exist, but with an increasing prevalence of antibiotic-resistant bacteria the successful management of impetigo in the future is an area of concern. COMMENT: Current treatment options that favour the use of oral antibiotic therapy are increasingly problematic. Widespread use of these agents contributes to antimicrobial resistance and has adverse consequences for individuals and communities. There is a need for new topical antimicrobials and antiseptics as an alternative treatment strategy. WHAT IS NEW AND CONCLUSION: To successfully treat impetigo into the future and ensure that therapy does not contribute to bacterial resistance, additional research is required to ascertain the usefulness of alternative agents, including new topical antimicrobials and antiseptics.

Stability of dobutamine in continuous ambulatory delivery devices.

WHAT IS KNOWN AND OBJECTIVE: Continuous infusion of dobutamine plays an important role in the management of patients with end-stage heart failure. Home infusion of dobutamine using a continuous ambulatory delivery device (CADD) facilitates the management of patients in their home, avoiding complications associated with long-term hospitalization. However, the stability of dobutamine in CADD is currently unknown. Therefore, this study investigated the physicochemical stability of dobutamine in CADDs at three different temperatures over various time points. METHODS: Six CADDs (three containing dobutamine 10 mg/mL in 0.9% sodium chloride and three containing dobutamine 10 mg/mL in 5% glucose) were prepared and stored at 4°C for 7 days, followed by 12 hours at 35°C and then for another 12 hours at 25°C. An aliquot (n = 3) was withdrawn aseptically at 0, 24, 48, 72, 96, 120, 144 and 168 hours when stored at 4°C, and at 0, 6 and 12 hours when stored at the other two temperatures. Each sample was analysed for dobutamine concentration using a stability-indicating high-performance liquid chromatography. All the samples were also evaluated for change in pH, colour and for particle content. RESULTS AND DISCUSSION: No evidence of particle formation, colour or pH change was observed throughout the study period. Dobutamine, when admixed with 0.9% sodium chloride or 5% glucose, was found to be chemically stable for at least 168 hours at 4°C and for another 12 hours at 35°C and for another 12 hours at 25°C. WHAT IS NEW AND CONCLUSIONS: Our findings will allow health professionals to provide a weekly supply of dobutamine-containing CADDs to patients for home infusions. Continuous infusion over a 24-hour period using one CADD per day will also decrease the number of exchanges required and thus reduce the risk of catheter-related bloodstream infections.

Pain intensity and pain self-management strategies following discharge after surgery: An Australian prospective observational study.

WHAT IS KNOWN AND OBJECTIVE: Up to 80% of patients experience acute pain following surgery. This study aimed to improve the current understanding about the strategies individuals use to self-manage pain following discharge after surgery, stratified by pain intensity. METHODS: A prospective observational study conducted at the Royal Hobart Hospital, Australia, between November 2014 and March 2015. Eligible participants were 18 years or older and had undergone surgery requiring an incision. Patients who had undergone surgery related to cancer, childbirth or multitrauma or those with dementia were excluded. Participants were identified through hospital records and mailed a survey within 1 week of discharge. This survey asked about post-discharge pain, management strategies utilized and advice on self-management of pain provided during their inpatient stay. RESULTS: Five hundred surveys were mailed, with 169 (33.8%) being returned. The median age of the respondents was 57 years (range: 18-92 years); 53% were female. The majority (89.3%) of participants recalled receiving information about pain self-management. Analgesic use was reported by 95.4% of participants in the week following discharge. Moderate-severe pain was reported by 80 participants (47.3%); 63.7% and 11.3% of patients reported underuse and overuse of analgesics compared to what was recommended, respectively. WHAT IS NEW AND CONCLUSION: A high proportion of patients underused analgesics despite experiencing moderate-severe pain. Although the vast majority of participants reported receiving advice regarding pain self-management, this did not appear to translate into optimal pain management after discharge. Different approaches to the provision of advice appear to be required.

Power outages and refrigerated medicines: The need for better guidelines, awareness and planning.

WHAT IS KNOWN AND OBJECTIVE: Vaccines and other pharmaceuticals are essential medical supplies that require continuous storage at specific temperatures to maintain viability. Power outages can lead to a break in the cold chain, resulting in the degradation of essential medicines. COMMENT: After a power outage, the stability of vaccines and other medicines can be difficult to ascertain. Many public health guidelines therefore recommend discarding potentially compromised pharmaceuticals unless the cold chain can be guaranteed-a costly endeavour. There are government guidelines aimed at minimizing exposure to high temperatures in the event of a power outage; however, the usefulness of these guidelines is uncertain. WHAT IS NEW AND CONCLUSION: The actual cost of vaccine and pharmaceutical loss due to a break in the cold chain is poorly studied and requires further research. Additional recommendations regarding the stability of specific medicines would also be a valuable resource.

From resilience thinking to Resilience Planning: Lessons from practice.

Resilience thinking has frequently been proposed as an alternative to conventional natural resource management, but there are few studies of its applications in real-world settings. To address this gap, we synthesized experiences from practitioners that have applied a resilience thinking approach to strategic planning, called Resilience Planning, in regional natural resource management organizations in Australia. This case represents one of the most extensive and long-term applications of resilience thinking in the world today. We conducted semi-structured interviews with Resilience Planning practitioners from nine organizations and reviewed strategic planning documents to investigate: 1) the key contributions of the approach to their existing strategic planning, and 2) what enabled and hindered the practitioners in applying and embedding the new approach in their organizations. Our results reveal that Resilience Planning contributed to developing a social-ecological systems perspective, more adaptive and collaborative approaches to planning, and that it clarified management goals of desirable resource conditions. Applying Resilience Planning required translating resilience thinking to practice in each unique circumstance, while simultaneously creating support among staff, and engaging external actors. Embedding Resilience Planning within organizations implied starting and maintaining longer-term change processes that required sustained multi-level organizational support. We conclude by identifying four lessons for successfully applying and embedding resilience practice in an organization: 1) to connect internal "entrepreneurs" to "interpreters" and "networkers" who work across organizations, 2) to assess the opportunity context for resilience practice, 3) to ensure that resilience practice is a learning process that engages internal and external actors, and 4) to develop reflective strategies for managing complexity and uncertainty.

Does the "script" need a rewrite? Is medication advice in television medical dramas appropriate?

WHAT IS KNOWN AND OBJECTIVE: Television medical dramas depict the healthcare industry and draw considerable interest from the public, while pharmacists play an integral part in providing medication-related advice to the public and other health practitioners in real life. The main objective of this retrospective, observational study was to assess the appropriateness of medication advice given in televised medical dramas and how frequently pharmacists were involved in providing the medication advice. METHODS: Show selection was based on fictional series with a medical drama theme and having the highest viewership. Approximately 100 randomly selected hours of five medical television dramas (House, Grey's Anatomy, Nurse Jackie, Doc Martin and Royal Pains) were assessed for the appropriateness of advice given based on the medication indicated, number of safety checks performed, and the level of adherence to standard clinical guidelines. The appropriateness of medication advice was assessed as appropriate, mostly appropriate, partially appropriate and inappropriate using a piloted, 0-6 point scale. Other parameters recorded included patient demographics, health professionals involved, and the categories of medicines. RESULTS AND DISCUSSIONS: Medications were mentioned on 424 occasions (on average four times per hour), including 239 occasions where medication advice was given. A pharmacist was involved in giving medication advice only 16 times (7%). Using the assessment tool, overall, medication advice was deemed to be appropriate 24% of the time, mostly appropriate 34%, partially appropriate 13% and inappropriate 7%. Although the medication advice given was often for the correct indication and the advice somewhat followed clinical guidelines, it frequently omitted adequate safety checks. Doc Martin had the highest mean appropriateness score, whereas House and Grey's Anatomy had the lowest. WHAT IS NEW AND CONCLUSIONS: Medication was often used for the correct indication in television medical dramas; however, key safety checks were frequently omitted and other medication-related advice, including dose, was less reliable and accurate. Pharmacists were rarely involved in providing medication advice. Viewers should not base medication-related decisions solely on what they see in television medical dramas, and any medication-related advice should be interpreted with extreme caution.

Scabies-An ancient itch that is still rampant today.

WHAT IS KNOWN AND OBJECTIVE: Scabies is recognized as a neglected tropical disease responsible for a substantial health and economic burden, especially in resource-poor communities around the world. COMMENT: There are relatively few current treatment options for scabies, and they possess important limitations. The treatments are ineffective in preventing relapse, inflammatory skin reactions and associated bacterial skin infections. There are also safety concerns, especially in children and pregnant women. Furthermore, there has been the emergence of resistance among scabies mites to the classical acaricides. WHAT IS NEW AND CONCLUSION: More research needs to be devoted to developing new treatments for scabies.

A robust sebum, oil, and particulate pollution model for assessing cleansing efficacy of human skin.

With increasing concerns over the rise of atmospheric particulate pollution globally and its impact on systemic health and skin ageing, we have developed a pollution model to mimic particulate matter trapped in sebum and oils creating a robust (difficult to remove) surrogate for dirty, polluted skin. OBJECTIVE: To evaluate the cleansing efficacy/protective effect of a sonic brush vs. manual cleansing against particulate pollution (trapped in grease/oil typical of human sebum). METHODS: The pollution model (Sebollution; sebum pollution model; SPM) consists of atmospheric particulate matter/pollution combined with grease/oils typical of human sebum. Twenty subjects between the ages of 18-65 were enrolled in a single-centre, cleansing study comparisons between the sonic cleansing brush (normal speed) compared to manual cleansing. Equal amount of SPM was applied to the centre of each cheek (left and right). Method of cleansing (sonic vs. manual) was randomized to the side of the face (left or right) for each subject. Each side was cleansed for five-seconds using the sonic cleansing device with sensitive brush head or manually, using equal amounts of water and a gel cleanser. Photographs (VISIA-CR, Canfield Imaging, NJ, USA) were taken at baseline (before application of the SPM), after application of SPM (pre-cleansing), and following cleansing. Image analysis (ImageJ, NIH, Bethesda, MD, USA) was used to quantify colour intensity (amount of particulate pollutants on the skin) using a scale of 0 to 255 (0 = all black pixels; 255 = all white pixels). Differences between the baseline and post-cleansing values (pixels) are reported as the amount of SPM remaining following each method of cleansing. RESULTS: Using a robust cleansing protocol to assess removal of pollutants (SPM; atmospheric particulate matter trapped in grease/oil), the sonic brush removed significantly more SPM than manual cleansing (P < 0.001). While extreme in colour, this pollution method easily allows assessment of efficacy through image analysis.

On the wettability transparency of graphene-coated silicon surfaces.

In order to better understand the behavior and governing characteristics of the wetting transparency phenomenon observed in graphene-coated surfaces, molecular dynamics simulations were coupled with a theoretical model. Graphene-coated silicon was selected for this analysis, due to potential applications of hybrid silicon-graphene materials as detectors in aqueous environments. The results indicate good agreement between the theory and simulations at the macroscopic conditions required to observe wetting transparency. A microscopic analysis was also conducted in order to identify the parameters, such as the interaction potential energy landscape and the interfacial liquid structure that govern the wetting behavior of graphene-coated surfaces. The interfacial liquid structure was found to be different between uncoated Si(100) and the graphene-coated version and very similar between uncoated Si(111) and the graphene-coated version. However, the concentration of liquid particles for both silicon surfaces was found to be very similar under transparent wetting conditions.

Residential medication management reviews of antithrombotic therapy in aged care residents with atrial fibrillation: assessment of stroke and bleeding risk.

WHAT IS KNOWN AND OBJECTIVE: Antithrombotics reduce the risk of stroke in individuals with atrial fibrillation (AF). However, optimal prescribing of antithrombotics in older people remains a challenge. The objective of this study was to assess the risk of stroke for aged care home residents with AF and to examine the pharmacist-led medication reviews on the utilization of antithrombotic therapy. METHODS: This retrospective study included a random sample of de-identified residential medication management reviews (RMMRs) conducted by accredited pharmacists in aged care homes in Sydney, Australia, between August 2011 and December 2012. The study participants were 146 residents aged 65 years and older with AF living in low- and high-care residential aged care facilities. Antithrombotic therapy was examined among the residents, before and after medication review. CHADS2 , CHA2 DS2 -VASc, and HEMORR2 HAGES scoring tools were used to assess the risk of stroke and bleeding and indicate the appropriateness of antithrombotic therapy. RESULTS AND DISCUSSION: The mean age (±SD) of individuals was 88·4 (7·5) years, and 63·7% (n = 93) were female. The majority of residents (n = 99, 67·8%) were aged between 85 and 99 years. The mean (±SD) CHADS2 score was 3·1 (1·1), CHA2 DS2 -VASc was 4·6 (1·5), and HEMORR2 HAGES was 2·3 (1·0). All residents were classified as being at high risk of developing stroke. A total of 115 of 146 (78·8%) residents with AF were prescribed antithrombotics. There was a relatively low usage of anticoagulation (28·1%), and few recommendations from the medication review pharmacists to alter the thromboprophylactic therapy in AF. Application of the CHA2 DS2 -VASc risk tool indicated that 146 residents were eligible for antithrombotic treatments; of these, 74 (50·7%) were prescribed antiplatelets and 41 (28·1%) were prescribed anticoagulants. Of the 31 (21·2%) residents with AF were not prescribed antithrombotics, 21 (67·7%) had relative contraindications for anticoagulant treatments. WHAT IS NEW AND CONCLUSION: Although there was a high overall use of antithrombotic agents, the study found a reluctance to prescribe or recommend anticoagulants in eligible older people with AF, potentially due to associated contraindications and multimorbidity. The use of guideline-recommended stroke risk tools could assist medication review pharmacists in optimizing antithrombotic therapy in older adults with AF.

Wettability of graphitic-carbon and silicon surfaces: MD modeling and theoretical analysis.

The wettability of graphitic carbon and silicon surfaces was numerically and theoretically investigated. A multi-response method has been developed for the analysis of conventional molecular dynamics (MD) simulations of droplets wettability. The contact angle and indicators of the quality of the computations are tracked as a function of the data sets analyzed over time. This method of analysis allows accurate calculations of the contact angle obtained from the MD simulations. Analytical models were also developed for the calculation of the work of adhesion using the mean-field theory, accounting for the interfacial entropy changes. A calibration method is proposed to provide better predictions of the respective contact angles under different solid-liquid interaction potentials. Estimations of the binding energy between a water monomer and graphite match those previously reported. In addition, a breakdown in the relationship between the binding energy and the contact angle was observed. The macroscopic contact angles obtained from the MD simulations were found to match those predicted by the mean-field model for graphite under different wettability conditions, as well as the contact angles of Si(100) and Si(111) surfaces. Finally, an assessment of the effect of the Lennard-Jones cutoff radius was conducted to provide guidelines for future comparisons between numerical simulations and analytical models of wettability.

Community-acquired pneumonia: why aren't national antibiotic guidelines followed?

AIMS: Adherence to guidelines for the management of community-acquired pneumonia (CAP) has been shown to improve patients' clinical outcomes. This study aimed to assess adherence to the Australian Therapeutic Guidelines (TG14) for the empirical management of CAP, and explore the potential barriers affecting adherence to these guidelines. METHODS: Medical records were reviewed for all patients who were diagnosed with CAP within 24 h of presentation at the Royal Hobart Hospital, the main teaching hospital in Tasmania, Australia, between July 2010 and March 2011. A survey of emergency department and medical team prescribers was also undertaken to identify potential barriers to adhere with the guidelines. χ(2) and Fisher's exact tests were used to test the significance between categorical data. To compare categorical and scale data, the Mann-Whitney U-test was used. RESULTS: A total of 193 patient records were assessed. The overall adherence to TG14 for the empirical antibiotic management of CAP was 16.1% (3.1%, 20.7% and 25.4% for patients with mild, moderate and severe CAP, respectively). Ceftriaxone was prescribed to 34.4%, 26.8% and 57.4% of patients with mild, moderate and severe CAP, respectively. The response rate to the barrier survey was 43.1%; of those who responded, 46.4% thought the influence of senior doctors on junior doctors could be a factor affecting adherence to the guidelines. Other barriers noted were a lack of guideline awareness (39.3%), the requirement to calculate the severity of CAP (35.7%), and the existence of other guidelines that conflict with TG14 (28.6%). CONCLUSIONS: Adherence to CAP treatment guidelines was poor, especially in patients with mild disease. Prescribing was mainly influenced by senior doctors. Efforts to improve compliance with CAP treatment guidelines should consider the potential barriers that hinder adherence.

Intervention fidelity for a complex behaviour change intervention in community pharmacy addressing cardiovascular disease risk.

BACKGROUND: Delivery of cardiovascular disease (CVD) prevention programs by community pharmacists appears effective and enhances health service access. However, their capacity to implement complex behavioural change processes during patient counselling remains largely unexplored. This study aims to determine intervention fidelity by pharmacists for behavioural components of a complex educational intervention for CVD prevention. After receiving training to improve lifestyle and medicines adherence, pharmacists recruited 70 patients aged 50-74 years without established CVD, and taking antihypertensive or lipid lowering therapy. Patients received five counselling sessions, each at monthly intervals. Researchers assessed biomedical and behavioural risk factors at baseline and six months. Pharmacists documented key outcomes from counselling after each session. Most patients (86%) reported suboptimal cardiovascular diets, 41% reported suboptimal medicines adherence, and 39% were physically inactive. Of those advised to complete the intervention, 85% attended all five sessions. Pharmacists achieved patient agreement with most recommended goals for behaviour change, and overwhelmingly translated goals into practical behavioural strategies. Barriers to changing behaviours were regularly documented, and pharmacists reported most behavioural strategies as having had some success. Meaningful improvements to health behaviours were observed post-intervention. Findings support further exploration of pharmacists' potential roles for delivering interventions with complex behaviour change requirements.
