A Qualitative Protocol for Evaluating Online Social Work Interventions for Cancer Survivors Using an AI-Enhanced WeChat Mini-Application
Cancer survivors in China face ongoing physiological, psychological, social, and spiritual challenges that significantly impact their quality of life. Despite the proliferation of online interventions, existing research lacks comprehensive exploration of integrating theoretical knowledge and practical experiences into the design of digital interventions for cancer survivors. To address these multidimensional needs and identified research gaps, th…
Matching the right study design to decision-maker questions
Research evidence can play an important role in each stage of decision-making, evidence-support systems play a key role in aligning the demand for and supply of evidence. This paper provides guidance on what type of study designs most suitably address questions asked by decision-makers. This study used a two-round online Delphi approach, including methodological experts in different areas, disciplines, and geographic locations. Participants prior…
Pedagogic Strategies and Contents in Medical Writing/Publishing Education
Workshops or training sessions on medical writing and publishing exist worldwide. We aimed to evaluate published articles about such workshops and examine both the content and teaching strategies employed. We searched ISI Web of Science, Ovid EMBASE, ERIC, Ovid Medline, and the grey literature. We considered no language, geographical location, or time period limitations. We included randomized controlled trials, before–after studies, surveys, coh…
Values and preferences influencing willingness to change red and processed meat consumption in response to evidence-based information
Objectives: The aim of the study is (1) to assess the extent to which omnivores are willing to stop or reduce their consumption of red and processed meat in response to evidence-based information regarding the possible reduction of cancer mortality and incidence achieved by dietary modification; (2) to identify socio-demographic categories associated with higher willingness to change meat consumption and (3) to understand the motives facilitating…
Association of Covid-19 With Achieving Time-to-Surgery Benchmarks in Patients With Musculoskeletal Trauma
In this cohort study, there was no association between meeting time-to-surgery benchmarks in either open fracture or closed femur/hip fracture during the COVID-19 pandemic compared with before the pandemic. This is counter to concerns that the unprecedented challenges associated with managing the COVID-19 pandemic would be associated with clinically significant delays in acute management of urgent surgical cases and suggests that many hospital sy…
Health Related Values and Preferences Regarding Meat Intake
When informed about the cancer incidence and mortality risks of meat consumption, most respondents would not reduce their intake. Public health and clinical nutrition guidelines should ensure that their recommendations are consistent with population values and preferences
Biomedical Authorship
Public health journals’ requirements for authors to disclose funding and conflicts of interest
The policies of the majority of public health journals do not require the reporting of important details such as the role of the funder, and non-financial COI. Journals and publishers should consider revising their editorial policies to ensure complete and transparent reporting of funding and COI

Considering health equity when moving from evidence-based guideline recommendations to implementation
The availability of evidence-based guidelines does not ensure their implementation and use in clinical practice or policy making. Inequities in health have been defined as those inequalities within or between populations that are avoidable, unnecessary and also unjust and unfair. Evidence-based clinical practice and public health guidelines ('guidelines') can be used to target health inequities experienced by disadvantaged populations, although g…
Values and preferences for oral antithrombotic therapy in patients with atrial fibrillation
BACKGROUND: Exploration of values and preferences in the context of anticoagulation therapy for atrial fibrillation (AF) remains limited. To better characterize the distribution of patient and physician values and preferences relevant to decisions regarding anticoagulation in patients with AF, we conducted interviews with patients at risk of developing AF and physicians who manage patients with AF. METHODS: We interviewed 96 outpatients and 96 ph…
Essential psychiatric medicines
Brazilian cities have no rigorous processes for selecting the drugs that appear on their lists, and drugs that do not appear on the reference lists represent a significant proportion of antidepressant and benzodiazepine use, resulting in public health and social problems
Dificultades en la interpretación de los resultados de la investigación biomédica relacionada con el manejo de pacientes con enfermedades crónicas no transmisibles
The progressive increase in the prevalence of chronic non-communicable diseases (CNCD) has generated a need to change the paradigms in interpreting research about therapeutic and disease control strategies. One aspect to keep in mind is the incorporation of risk awareness that CNCD treatment implies, which creates uncertainty in the treatment result, compared to the curative paradigm that occurs in communicable diseases where a cure is expected. …
GRADE guidelines
The GRADE approach and Bradford Hill's criteria for causation
This article describes how the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach to grading the quality of evidence and strength of recommendations considers the Bradford Hill criteria for causation and how GRADE may relate to questions in public health. A primary concern in public health is that evidence from non-randomised studies may provide a more adequate or best available measure of a public health strategy'…
A treatment decision aid may increase patient trust in the diabetes specialist. The Statin Choice randomized trial
Aims Decision aids in practice may affect patient trust in the clinician, a requirement for optimal diabetes care. We sought to determine the impact of a decision aid to help patients with diabetes decide about statins ( Statin Choice ) on patients’ trust in the clinician. Methods We randomized 16 diabetologists and 98 patients with type 2 diabetes referred to a subspecialty diabetes clinic to use the Statin Choice decision aid or a patient pamph…

Users' guides to the medical literature
The accurate interpretation of mortality surveys in humanitarian crises is useful for both public health responses and security responses. Recent examples suggest that few medical personnel and researchers can accurately interpret the validity of a mortality survey in these settings. Using an example of a mortality survey from the Democratic Republic of Congo (DRC), we demonstrate important methodological considerations that readers should keep i…

Addressing the Unit of Analysis in Medical Care Studies
OBJECTIVE: We assessed the frequency that patients are incorrectly used as the unit of analysis among studies of physicians' patient care behavior in articles published in high impact journals. METHODS: We surveyed 30 high-impact journals across 6 medical fields for articles susceptible to unit of analysis errors published from 1994 to 2005. Three reviewers independently abstracted articles using previously published criteria to determine the pre…
Adherence to Antiretroviral Therapy in Sub-Saharan Africa and North America
CONTEXT: Adherence to antiretroviral therapy is a powerful predictor of survival for individuals living with human immunodeficiency virus (HIV) and AIDS. Concerns about incomplete adherence among patients living in poverty have been an important consideration in expanding the access to antiretroviral therapy in sub-Saharan Africa. OBJECTIVE: To evaluate estimates of antiretroviral therapy adherence in sub-Saharan Africa and North America. DATA SO…

Measurement of health status
Evidence-Based Medicine
A NEW paradigm for medical practice is emerging. Evidence-based medicine de-emphasizes intuition, unsystematic clinical experience, and pathophysiologic rationale as sufficient grounds for clinical decision making and stresses the examination of evidence from clinical research. Evidence-based medicine requires new skills of the physician, including efficient literature searching and the application of formal rules of evidence evaluating the clini…
Measuring Health-Related Quality of Life
Clinicians and policymakers are recognizing the importance of measuring health-related quality of life (HRQL) to inform patient management and policy decisions. Self- or interviewer-administered questionnaires can be used to measure cross-sectional differences in quality of life between patients at a point in time (discriminative instruments) or longitudinal changes in HRQL within patients during a period of time (evaluative instruments). Both di…

Methods to Explain the Clinical Significance of Health Status Measures
Validity and Reliability of a Questionnaire for Measuring Child Oral-health-related Quality of Life
Oral-health-related quality of life measures that exist are designed for adults. This study aimed to develop and evaluate the CPQ 11-14 , a self-report measure of the impact of oral and oro-facial conditions on 11- to 14-year-old children. An item pool was generated with the use of a literature review and interviews with health professionals, parents, and child patients. The 36 items rated the most frequent and bothersome by 83 children were sele…

A Randomized Multicenter Trial to Evaluate Simple Utility Elicitation Techniques in Patients With Gastroesophageal Reflux Disease
BACKGROUND: Despite recommendations that patients rating their own health using utility and preference measures such as the feeling thermometer (FT) and standard gamble (SG) should also rate hypothetical marker states, little evidence supports marker state use. We evaluated whether the administration of marker states improves measurement properties of the FT and SG. METHODS: We randomized 217 patients with gastroesophageal reflux disease to compl…
