Medical practice and the disease model importantly rely on the accuracy assumption of symptom perception: patients’ symptom reports are a direct and accurate reflection of physiological dysfunction. This implies that symptoms can be used as a read-out of dysfunction and that remedying the dysfunction removes the symptoms. While this assumption is viable in many instances of disease, the relationship between symptoms and physiological dysfunction is highly variable and, in a substantial number of cases, completely absent. This chapter considers symptom perception as a form of unconscious inferential somatic decision-making that compellingly produces consciously experienced symptoms. At a mechanistic level, this perspective removes the categorical distinction between symptoms that are closely associated with physiological dysfunction and those that are not. In addition, it brings symptom perception in accordance with general theories of perception. Some clinical implications to understand and treat symptoms poorly related to physiological dysfunction are discussed.

(1) Background: Integrated models of primary care deliver the comprehensive and preventative approach needed to identify and manage frailty in older people. Seniors’ Community Hub (SCH) was developed to deliver person-centered, evidence-informed, coordinated, and integrated care services to older community dwelling adults living with frailty. This paper aims to describe the SCH model, and to present patient-oriented results of the pilot. (2) Methods: SCH was piloted in an academic clinic with six family physicians. Eligible patients were community dwelling, 65 years of age and older, and considered to be at risk of frailty (eFI > 0.12). Health professionals within the clinic received training in geriatrics and interprofessional teamwork to form the SCH team working with family physicians, patients and caregivers. The SCH intervention consisted of a team-based multi-domain assessment with person-centered care planning and follow-up. Patient-oriented outcomes (EQ-5D-5L and EQ-VAS) and 4-metre gait speed were measured at initial visit and 12 months later. (3) Results: 88 patients were enrolled in the pilot from April 2016–December 2018. No statistically significant differences in EQ-5D-5L/VAS or the 4-metre gait speed were detected in 38 patients completing the 12-month assessment. (4) Conclusions: Future larger scale studies of longer duration are needed to demonstrate impacts of integrated models of primary care on patient-oriented outcomes for older adults living with frailty.

This study evaluated the effects of different matching methods on the accuracy of dentofacial integration in stereophotogrammetry and smartphone face-scanning systems. The integration was done (N = 30) with different matching areas (n = 10), including teeth image only (TO), perioral area without markers (PN) and with markers (PM). The positional accuracy of the integrated models was assessed by measuring the midline linear deviations and incisal line canting between the experimental groups and laser scanner-based reference standards. Kruskal–Wallis and Mann–Whitney U tests were used for statistical analyses (α = 0.05). The PM method exhibited the smallest linear deviations in both systems; while the highest deviations were found in the TO in stereophotogrammetry; and in PN in smartphone. For the incisal line canting; the canting degree was the lowest in the PM method; followed by that in the TO and the PN in both systems. Although stereophotogrammetry generally exhibited higher accuracy than the smartphone; the two systems demonstrated no significant difference when the perioral areas were used for matching. The use of perioral scans with markers enables accurate dentofacial image integration; however; cautions should be given on the accuracy of the perioral image obtained without the use of markers.

Abstract Background Increasingly, treatment for opioid use disorder (OUD) is offered in integrated treatment models addressing both substance use and other health conditions within the same system. This often includes offering medications for OUD in general medical settings. It remains uncertain whether integrated OUD treatment models are preferred to non-integrated models, where treatment is provided within a distinct treatment system. This study aimed to explore preferences for integrated versus non-integrated treatment models among people with OUD and examine what factors may influence preferences. Methods This qualitative study recruited participants (n = 40) through Craigslist advertisements and flyers posted in treatment programs across the United States. Participants were 18 years of age or older and scored a two or higher on the heroin or opioid pain reliever sections of the Tobacco, Alcohol, Prescription Medications, and Other Substances (TAPS) Tool. Each participant completed a demographic survey and a telephone interview. The interviews were coded and content analyzed. Results While some participants preferred receiving OUD treatment from an integrated model in a general medical setting, the majority preferred non-integrated models. Some participants preferred integrated models in theory but expressed concerns about stigma and a lack of psychosocial services. Tradeoffs between integrated and non-integrated models were centered around patient values (desire for anonymity and personalization, fear of consequences), the characteristics of the provider and setting (convenience, perceived treatment effectiveness, access to services), and the patient-provider relationship (disclosure, trust, comfort, stigma). Conclusions Among this sample of primarily White adults, preferences for non-integrated versus integrated OUD treatment were mixed. Perceived benefits of integrated models included convenience, potential for treatment personalization, and opportunity to extend established relationships with medical providers. Recommendations to make integrated treatment more patient-centered include facilitating access to psychosocial services, educating patients on privacy, individualizing treatment, and prioritizing the patient-provider relationship. This sample included very few minorities and thus findings may not be fully generalizable to the larger population of persons with OUD. Nonetheless, results suggest a need for expansion of both OUD treatment in specialty and general medical settings to ensure access to preferred treatment for all.

IntroductionSymptom perception in heart failure (HF) has been identified as crucial for effective self-care, and is related to patient and health system outcomes. There is uncertainty regarding the feasibility and acceptability of symptom perception support and doubts regarding how to include informal caregivers. This study aims to test the feasibility, acceptability and outcome responsiveness of an intervention supporting symptom perception in persons with HF and their informal caregiver.Methods and analysisA feasibility study with a quasi-experimental pretest and post-test single group design is conducted. The convenience sample consists of 30 persons with HF, their informal caregivers and six nurses. SYMPERHEART is an evidence-informed intervention that targets symptom perception by educational and support components. Feasibility is measured by time-to-recruit; time-to-deliver; eligibility rate; intervention delivery fidelity rate. Acceptability is measured by rate of consent, retention rate, treatment acceptability and the engagement in the intervention components. Outcome responsiveness includes: HF self-care (via the Self-care of Heart Failure Index V.7.2); perception of HF symptom burden (via the Heart Failure Somatic Perception Scale V.3); health status (via the Kansas City Cardiomyopathy Questionnaire-12); caregivers’ contribution to HF self-care (via the Caregiver Contribution to Self-Care of Heart Failure Index 2); caregivers’ burden (via the Zarit Burden Interview). Clinical outcomes include HF events, hospitalisation reason and length of hospital stay. Descriptive statistics will be used to report feasibility, acceptability, patient-reported outcomes (PRO) and clinical outcomes. PRO and caregiver-reported outcome responsiveness will be reported with mean absolute change and effect sizes.Ethics and disseminationThe study is conducted according to the Declaration of Helsinki. The Human Research Ethics Committee of the Canton of Vaud, Switzerland, has approved the study. Written informed consent from persons with HF and informal caregivers are obtained. Results will be published via peer reviewed and professional journals, and further disseminated via congresses.Trial registration numberISRCTN18151041.

Multiple interrelated decision-making models are frequently used in supply chain modeling. Model integration is a precondition for efficient development and utilization of these models. This paper discusses use of modern information technology (IT) techniques and methods for integration of supply chain decision-making models. The overall approach to using IT at various stages of model development is presented. Data and process modeling techniques are used to developed semi-formalized representation of integrated models. These models support integration of decision-making components with other parts of supply chain information system. Process modeling is also used to describe interrelationships among multiple decision-making models. This representation is used as the basis for implementation of integrated models. The service-oriented architecture is proposed as an implementation platform. The presented discussion serves as the basis for further developments in developing integrated supply chain decision-making models.
