BACKGROUND: By 2030, prostate cancer will be the most commonly diagnosed cancer in North America. To mitigate this impending challenge, comprehensive support mechanisms for disease- and treatment-specific changes in health and well-being must be proactively designed and thoughtfully implemented for streamlined survivorship care. mHealth apps have been lauded as a promising complement to current outpatient treatment and monitoring strategies, but have not yet been widely used to support prostate cancer survivorship needs...

Surgery in elderly patients is associated with the risk of death, complications, functional decline and disability. Prior to surgery, therefore, an assessment of the health-related priorities, a realistic evaluation of the surgical risks, and individualized optimization of the procedural pathway to follow are mandatory.

BACKGROUND: During the last years, randomized designs have been promoted as the cornerstone of evidence-based policymaking. Also in the field of community participation, Random Control Trials (RCTs) have been the dominant design, used for instance to examine the contribution of community participation to health improvement. We aim at clarifying why RCTs and related (quasi-) experimental designs may not be the most appropriate approach to evaluate such complex programmes. RESULTS: We argue that the current methodological debate could be more fruitful if it would start from the position that the choice of designs should fit the nature of the program and research questions rather than be driven by methodological preferences...

Nancy Cartwright, Jeremy Hardie
This paper offers some rules of thumb that practicing social workers can use for case studies that aim to construct, albeit not fully and never entirely reliably, models designed to help predict what will happen if they intervene in specific ways to help this particular client, here and now. We call these 'ex ante case-specific causal models'. 'Ex ante' because they are for before-the-fact prediction of what the likely effects of proposed actions are. 'Case-specific' because we are not concerned with studies that provide evidence for some general conclusion but rather with using what general and local knowledge one can get to predict what will happen to a specific client in the real settings in which they live...

INTRODUCTION: It is increasingly acknowledged that differentiated care models hold potential to manage large volumes of patients on antiretroviral therapy (ART). Various group-based models of ART service delivery aimed at decongesting local health facilities, encouraging patient retention in care, and enhancing adherence to medication have been implemented across sub-Saharan Africa. Evidence from the literature suggests that these models of ART service delivery are more effective than corresponding facility-based care and superior to individual-based models...

Most studies investigating the influence of TiO2 NPs on heavy metal bioavailability have focused on the aqueous phase; however, few have examined the sediments containing more nanoparticles. Here, we investigated the effects of TiO2 NPs on heavy metal bioavailability in C. fluminea in sediments. The interactions between the TiO2 NPs and metals in sediments, the influence of TiO2 NPs on metals levels in aqueous phase and geochemical speciation were also explored. The results indicated the large adsorption capacity of TiO2 NPs and the strong adsorption affinity to metals caused the metals adsorbed on nanoparticles, which decreased the metals concentrations in water phase...

Schwartz Rounds are evidence-based interdisciplinary discussions where health care staff can share experiences of the emotional and social aspects of care, to support improvements in patient care. Developed in acute services, they are now being implemented in various settings including U.K. community and mental health services where their implementation has not been researched. Realist evaluation was used to analyze three community and mental health case studies of Round implementation, involving Round observations ( n = 5), staff interviews ( n = 22), and post-Round evaluation sheets ( n = 206)...

CONTEXT: Doctors must be competent from their first day of practice if patients are to be safe. Medical students and new doctors are acutely aware of this, but describe being variably prepared. OBJECTIVES: This study aimed to identify causal chains of the contextual factors and mechanisms that lead to a trainee being capable (or not) of completing tasks for the first time. METHODS: We studied three stages of transition: anticipation; lived experience, and post hoc reflection...

Participatory intervention approaches that are embedded in existing organizational structures may improve the efficiency and effectiveness of organizational interventions, but concrete tools are lacking. In the present article, we use a realist evaluation approach to explore the role of kaizen, a lean tool for participatory continuous improvement, in improving employee well-being in two cluster-randomized, controlled participatory intervention studies. Case 1 is from the Danish Postal Service, where kaizen boards were used to implement action plans...

OBJECTIVE: Dexterous upper-limb prostheses are available today to restore grasping, but an effective and reliable feed-forward control is still missing. The aim of this work was to improve the robustness and reliability of myoelectric control by using context information from sensors embedded within the prosthesis. APPROACH: We developed a context-driven myoelectric control scheme (cxMYO) that incorporates the inference of context information from proprioception (inertial measurement unit) and exteroception (force and grip aperture) sensors to modulate the outputs of myoelectric control...

INTRODUCTION: Responsiveness to service users' views is a widely recognised objective of health systems. A key component of responsive health systems is effective interaction between users and service providers. Despite a growing literature on patient feedback from high-income settings, less is known about effectiveness of such systems in low-income and middle-income countries. METHODOLOGY AND ANALYSIS: This paper disseminates the protocol for an 18-month 'RESPOND' project that aims to evaluate the system of collecting and responding to user feedback in Bangladesh...

Researchers have described the documentation practices of perioperative nurses as flawed and characterized by subjectivity and poor quality, which is often related to both the documentation tool and the nurses' level of commitment. Studies suggest that documentation of nursing care in the OR places special demands on electronic health records (EHRs). The purpose of this study was to explore how the use of an EHR tailored to perioperative practice affects Danish perioperative nurses' documentation practices...

BACKGROUND: Evidence-based decision-making and practice are pivotal in public health. However, barriers do persist and they relate to evidence properties, organisations and contexts. To address these major knowledge transfer (KT) issues, we need to rethink how knowledge is produced and used, to enhance our understanding of decision-making processes, logics and mechanisms and to examine the ability of public health services to integrate research findings into their decisions and operations...

This paper discusses what was learned about evaluation capacity building with community organizations who deliver services to individuals with neurological disorders. Evaluation specialists engaged by the Ontario Brain Institute Evaluation Support Program were paired with community organizations, such as Dancing With Parkinson's. Some of the learning included: relationship building is key for this model of capacity building; community organizations often have had negative experiences with evaluation and the idea that evaluations can be friendly tools in implementing meaningful programs is one key mechanism by which such an initiative can work; community organizations often need evaluation most to be able to demonstrate their value; a strength of this initiative was that the focus was not just on creating products but mostly on developing a learning process in which capacities would remain; evaluation tools and skills that organizations found useful were developing a theory of change and the concept of heterogeneous mechanisms (informed by a realist evaluation lens)...

INTRODUCTION: In developed countries, substituting physicians with nurse practitioners, physician assistants and nurses (physician substitution) occurs in nursing homes as an answer to the challenges related to the ageing population and the shortage of staff, as well as to guarantee the quality of nursing home care. However, there is great diversity in how physician substitution in nursing homes is modelled and it is unknown how it can best contribute to the quality of healthcare. This study aims to gain insight into how physician substitution is modelled and whether it contributes to perceived quality of healthcare...

BACKGROUND: In the United Kingdom, stroke is the single largest cause of adult disability and results in a cost to the economy of £8.9 billion per annum. Service needs are currently not being met; therefore, initiatives that focus on patient-centered care that promote long-term self-management for chronic conditions should be at the forefront of service redesign. The use of innovative technologies and the ability to apply these effectively to promote behavior change are paramount in meeting the current challenges...
