TL;DR: Knowing the patient as a person allows the health professional to understand elements that are crucial to the patient's adherence: beliefs, attitudes, subjective norms, cultural context, social supports, and emotional health challenges, particularly depression.
Abstract: Quality healthcare outcomes depend upon patients' adherence to recommended treatment regimens. Patient nonadherence can be a pervasive threat to health and wellbeing and carry an appreciable economic burden as well. In some disease conditions, more than 40% of patients sustain significant risks by misunderstanding, forgetting, or ignoring healthcare advice. While no single intervention strategy can improve the adherence of all patients, decades of research studies agree that successful attempts to improve patient adherence depend upon a set of key factors. These include realistic assessment of patients' knowledge and understanding of the regimen, clear and effective communication between health professionals and their patients, and the nurturance of trust in the therapeutic relationship. Patients must be given the opportunity to tell the story of their unique illness experiences. Knowing the patient as a person allows the health professional to understand elements that are crucial to the patient's adherence: beliefs, attitudes, subjective norms, cultural context, social supports, and emotional health challenges, particularly depression. Physician–patient partnerships are essential when choosing amongst various therapeutic options to maximize adherence. Mutual collaboration fosters greater patient satisfaction, reduces the risks of nonadherence, and improves patients' healthcare outcomes.

TL;DR: Impact for improving physician-patient relationship outcomes through communication skills training is discussed, and implications for improving physicians' satisfaction with interpersonal aspects of professional life are discussed.
Abstract: Objective: To assess the effects of a communication skills training program for physicians and patients. Design: A randomized experiment to improve physician communication skills was assessed 1 and 6 months after a training intervention; patient training to be active participants was assessed after 1 month. Across three primary medical care settings, 156 physicians treating 2,196 patients were randomly assigned to control group or one of three conditions (physician, patient, or both trained). Main Outcome Measures: Patient satisfaction and perceptions of choice, decision-making, information, and lifestyle counseling; physicians’ satisfaction and stress; and global ratings of the communication process. Results: The following significant (p .05) effects emerged: physician training improved patients’ satisfaction with information and overall care; increased willingness to recommend the physician; increased physicians’ counseling (as reported by patients) about weight loss, exercise, and quitting smoking and alcohol; increased physician satisfaction with physical exam detail; increased independent ratings of physicians’ sensitive, connected communication with their patients, and decreased physician satisfaction with interpersonal aspects of professional life. Patient training improved physicians’ satisfaction with data collection; if only physician or patient was trained, physician stress increased and physician satisfaction decreased. Conclusion: Implications for improving physician-patient relationship outcomes through communication skills training are discussed.

TL;DR: This review offers guidelines for improved physician-older patient communication in medical practice, and examines interventions to coordinate care for older patients on multiple dimensions of a biopsychosocial model of health care.
Abstract: There is growing evidence that the outcomes of health care for seniors are dependent not only upon patients' physical health status and the administration of care for their biomedical needs, but also upon care for patients' psychosocial needs and attention to their social, economic, cultural, and psychological vulnerabilities. Even when older patients have appropriate access to medical services, they also need effective and empathic communication as an essential part of their treatment. Older patients who are socially isolated, emotionally vulnerable, and economically disadvantaged are particularly in need of the social, emotional, and practical support that sensitive provider-patient communication can provide. In this review paper, we examine the complexities of communication between physicians and their older patients, and consider some of the particular challenges that manifest in providers' interactions with their older patients, particularly those who are socially isolated, suffering from depression, or of minority status or low income. This review offers guidelines for improved physician-older patient communication in medical practice, and examines interventions to coordinate care for older patients on multiple dimensions of a biopsychosocial model of health care.

TL;DR: Ratings of affect in the CF voices of physicians and nurses correlated with their patients’ satisfaction, and theCF voices of nurses and patients reflected their satisfaction, suggesting reciprocity in their vocal affective communication
Abstract: Two studies examined vocal affect in medical providers’ and patients’ content-filtered (CF) speech. A digital methodology for content-filtering and a set of reliable global affect rating scales for CF voice were developed. In Study 1, ratings of affect in physicians’ CF voice correlated with patients’ satisfaction, perceptions of choice/control, medication adherence, mental and physical health, and physicians’ satisfaction. In Study 2, ratings of affect in the CF voices of physicians and nurses correlated with their patients’ satisfaction, and the CF voices of nurses and patients reflected their satisfaction. Voice tone ratings of providers and patients were intercorrelated, suggesting reciprocity in their vocal affective communication.

TL;DR: Educational meetings alone or combined with other interventions, can improve professional practice and healthcare outcomes for the patients and is most likely to be small and similar to other types of continuing medical education, such as audit and feedback, and educational outreach visits.
Abstract: Background Educational meetings are widely used for continuing medical education. Previous reviews found that interactive workshops resulted in moderately large improvements in professional practice, whereas didactic sessions did not. Objectives To assess the effects of educational meetings on professional practice and healthcare outcomes. Search methods We updated previous searches by searching the Cochrane Effective Practice and Organisation of Care Group Trials Register and pending file, from 1999 to March 2006. Selection criteria Randomised controlled trials of educational meetings that reported an objective measure of professional practice or healthcare outcomes. Data collection and analysis Two authors independently extracted data and assessed study quality. Studies with a low or moderate risk of bias and that reported baseline data were included in the primary analysis. They were weighted according to the number of health professionals participating. For each comparison, we calculated the risk difference (RD) for dichotomous outcomes, adjusted for baseline compliance; and for continuous outcomes the percentage change relative to the control group average after the intervention, adjusted for baseline performance. Professional and patient outcomes were analysed separately. We considered 10 factors to explain heterogeneity of effect estimates using weighted meta-regression supplemented by visual analysis of bubble and box plots. Main results In updating the review, 49 new studies were identified for inclusion. A total of 81 trials involving more than 11,000 health professionals are now included in the review. Based on 30 trials (36 comparisons), the median adjusted RD in compliance with desired practice was 6% (interquartile range 1.8 to 15.9) when any intervention in which educational meetings were a component was compared to no intervention. Educational meetings alone had similar effects (median adjusted RD 6%, interquartile range 2.9 to 15.3; based on 21 comparisons in 19 trials). For continuous outcomes the median adjusted percentage change relative to control was 10% (interquartile range 8 to 32%; 5 trials). For patient outcomes the median adjusted RD in achievement of treatment goals was 3.0 (interquartile range 0.1 to 4.0; 5 trials). Based on univariate meta-regression analyses of the 36 comparisons with dichotomous outcomes for professional practice, higher attendance at the educational meetings was associated with larger adjusted RDs (P < 0.01); mixed interactive and didactic education meetings (median adjusted RD 13.6) were more effective than either didactic meetings (RD 6.9) or interactive meetings (RD 3.0). Educational meetings did not appear to be effective for complex behaviours (adjusted RD -0.3) compared to less complex behaviours; they appeared to be less effective for less serious outcomes (RD 2.9) than for more serious outcomes. Authors' conclusions Educational meetings alone or combined with other interventions, can improve professional practice and healthcare outcomes for the patients. The effect is most likely to be small and similar to other types of continuing medical education, such as audit and feedback, and educational outreach visits. Strategies to increase attendance at educational meetings, using mixed interactive and didactic formats, and focusing on outcomes that are likely to be perceived as serious may increase the effectiveness of educational meetings. Educational meetings alone are not likely to be effective for changing complex behaviours.

TL;DR: A 2001 systematic review of the effects of these training interventions for healthcare providers that aim to promote patient-centred care in clinical consultations was updated by as discussed by the authors, who found 29 new randomized trials (up to June 2010), bringing the total of studies included in the review to 43.
Abstract: Problems may arise when healthcare providers focus on managing diseases rather than on people and their health problems. Patient-centred approaches to care delivery in the patient encounter are increasingly advocated by consumers and clinicians and incorporated into training for healthcare providers. The authors updated a 2001 systematic review of the effects of these training interventions for healthcare providers that aim to promote patient-centred care in clinical consultations. They found 29 new randomized trials (up to June 2010), bringing the total of studies included in the review to 43. In most of the studies, training interventions were directed at primary care physicians (general practitioners, internists, paediatricians or family doctors) or nurses practising in community or hospital outpatient settings. Some studies trained specialists. Patients were predominantly adults with general medical problems, though two studies included children with asthma. These studies showed that training providers to improve their ability to share control with patients about topics and decisions addressed in consultations are largely successful in teaching providers new skills. Short-term training (less than 10 hours) is as successful in this regard as longer training. Results are mixed about whether patients are more satisfied when providers practice these skills. The impact on general health is also mixed, although the limited data that could be pooled showed small positive effects on health status. Patients' specific health behaviours show improvement in the small number of studies where interventions use provider training combined with condition-specific educational materials and/or training for patients, such as teaching question-asking during the consultation or medication-taking after the consultation. However, the number of studies is too small to determine which elements of these multi-faceted studies are essential in helping patients change their healthcare behaviours.

TL;DR: Reduced, behaviourally driven gamma oscillations before the onset of plaque formation or cognitive decline in a mouse model of Alzheimer's disease uncover a previously unappreciated function of gamma rhythms in recruiting both neuronal and glial responses to attenuate Alzheimer's-disease-associated pathology.
Abstract: Changes in gamma oscillations (20–50 Hz) have been observed in several neurological disorders. However, the relationship between gamma oscillations and cellular pathologies is unclear. Here we show reduced, behaviourally driven gamma oscillations before the onset of plaque formation or cognitive decline in a mouse model of Alzheimer’s disease. Optogenetically driving fast-spiking parvalbumin-positive (FS-PV)-interneurons at gamma (40 Hz), but not other frequencies, reduces levels of amyloid-β (Aβ)1–40 and Aβ 1–42 isoforms. Gene expression profiling revealed induction of genes associated with morphological transformation of microglia, and histological analysis confirmed increased microglia co-localization with Aβ. Subsequently, we designed a non-invasive 40 Hz light-flickering regime that reduced Aβ1–40 and Aβ1–42 levels in the visual cortex of pre-depositing mice and mitigated plaque load in aged, depositing mice. Our findings uncover a previously unappreciated function of gamma rhythms in recruiting both neuronal and glial responses to attenuate Alzheimer’s-disease-associated pathology. Mouse models of Alzheimer’s disease show reduced, behaviourally driven gamma oscillations before the onset of plaque formation or cognitive decline; driving neurons to oscillate at gamma frequency (40 Hz) reduces levels of amyloid-β peptides. Disrupted gamma rhythms—oscillations in the brain's neuronal circuits at around 20–50 Hz—are hallmarks of various neurological disorders and have been seen in patients with Alzheimer's disease and specific mouse models of the disease. Li-Huei Tsai and colleagues show that gamma oscillations are also disrupted in the 5XFAD mouse model of Alzheimer's disease, and find reduced gamma prior to plaque formation and cognitive decline. Remarkably, by training neurons to oscillate at gamma frequency (40 Hz) in multiple mouse models including APP/PS1 and wild-type mice, amyloid-β peptide levels could be reduced.
