Clinical public health: harnessing the best of both worlds in sickness and in health.

Introduction: Effective, sustained collaboration between clinical and public health professionals can lead to improved individual and population health. The concept of clinical public health promotes collaboration between clinical medicine and public health to address complex, real-world health challenges. In this commentary, we describe the concept of clinical public health, the types of complex problems that require collaboration between individual and population health, and the barriers towards and applications of clinical public health that have become evident during the COVID-19 pandemic.

Defining Clinical Public Health.

Purpose: To solve complex health issues, an innovative and multidisciplinary framework is necessary. The Clinical Public Health (CPH) Division was established at the University of Toronto (UofT), Canada to foster inte-gration of primary care, preventive medicine and public health in education, practice and research. To better understand how the construct of CPH might be applied, we surveyed clinicians, researchers and public health professionals affiliated with the CPH Division to assess their understanding of the CPH concept and its utility in fostering broad collaboration.

Characteristics of Anti-SARS-CoV-2 Antibodies in Recovered COVID-19 Subjects.

Coronavirus Disease 2019 (COVID-19) is a global pandemic caused by the novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). While detection of SARS-CoV-2 by polymerase chain reaction with reverse transcription (RT-PCR) is currently used to diagnose acute COVID-19 infection, serological assays are needed to study the humoral immune response to SARS-CoV-2. Anti-SARS-CoV-2 immunoglobulin (Ig)G/A/M antibodies against spike (S) protein and its receptor-binding domain (RBD) were characterized in recovered subjects who were RT-PCR-positive ( = 153) and RT-PCR-negative ( = 55) using an enzyme-linked immunosorbent assay (ELISA).

Integrating clinical medicine and population health: where to from here?

Efforts to contain healthcare costs have led a renewed clinician interest in addressing population-level outcomes, with some proposing that the integration of population health into clinical practice represents a novel concept entitled "clinical population medicine" (CPM). This commentary offers an examination of the function and utility of CPM. In reviewing relevant literature, we note several inconsistencies in CPM's purported mandate, which ranges from simply incorporating the social determinants of health into clinical practice to broad involvement in community health planning.

Exploring the experience of residents during the first six months of family medicine residency training.

Background: The shift from undergraduate to postgraduate education signals a new phase in a doctor's training. This study explored the resident's perspective of how the transition from undergraduate to postgraduate (PGME) training is experienced in a Family Medicine program as they first meet the reality of feeling and having the responsibility as a .

Methods: Qualitative methods explored resident experiences using interpretative inquiry through monthly, individual in-depth interviews with five incoming residents during the first six months of training.

Choosing Wisely® in Preventive Medicine: The American College of Preventive Medicine's Top 5 List of Recommendations.

The Choosing Wisely(®) initiative is a national campaign led by the American Board of Internal Medicine Foundation, focused on quality improvement and advancing a dialogue on avoiding wasteful or unnecessary medical tests, procedures, and treatments. The American College of Preventive Medicine (ACPM) Prevention Practice Committee is an active participant in the Choosing Wisely project. The committee created the ACPM Choosing Wisely Task Force to lead the development of ACPM's recommendations with the intention of facilitating wise decisions about the appropriate use of preventive care.

The American College of Preventive Medicine Position Statement on Hepatitis C Virus Infection.

The American College of Preventive Medicine Prevention Practice Committee contributes to policy guidelines and recommendations on preventive health topics for clinicians and public health decision makers. After review of the currently available evidence, the College is providing a consensus-based set of recommendations designed to increase screening for and prevention of hepatitis C virus infection, increase linkage to care, improve access to treatment, and encourage development of hepatitis C virus-related quality measures.

Preventing texting while driving: a statement of the American College of Preventive Medicine.

The American College of Preventive Medicine (ACPM) is providing a set of recommendations designed to reduce the morbidity and mortality associated with distractions due to texting while driving. According to the National Highway Traffic Safety Administration, 12% of all fatal crashes involving at least one distracted driver are estimated to be related to cell phone use while driving. Given the combination of visual, manual, and cognitive distractions posed by texting, this is an issue of major public health concern for communities.

A look to the past as we look ahead: the specialty of public health medicine in Canada.

In February 2011, the medical specialty of Community Medicine was renamed as Public Health and Preventive Medicine (PHPM) to better reflect the roles and responsibilities of physician specialists in this field. While physician involvement in public health began in the early 20th century, the development of the formal PHPM specialty has closely paralleled the evolution of the Royal College of Physicians and Surgeons of Canada. At present, despite shortages identified in light of public health crises, recent specialist graduates in PHPM have reportedly experienced some difficulties finding optimal employment.

Optimizing Canadian breast cancer screening strategies: a perspective for action.

While controversies regarding optimal breast cancer screening modalities, screening start and end ages, and screening frequencies continue to exist, additional population-based randomized trials are unlikely to be initiated to examine these concerns. Simulation models have been used to evaluate the efficacy and effectiveness of various breast cancer screening strategies, however these models were all developed using US data. Currently, there is a need to examine the optimal screening and treatment policies in the Canadian context.

Predictors of competing mortality to invasive breast cancer incidence in the Canadian National Breast Screening study.

Background: Evaluating the cost-effectiveness of breast cancer screening requires estimates of the absolute risk of breast cancer, which is modified by various risk factors. Breast cancer incidence, and thus mortality, is altered by the occurrence of competing events. More accurate estimates of competing risks should improve the estimation of absolute risk of breast cancer and benefit from breast cancer screening, leading to more effective preventive, diagnostic, and treatment policies.

Incidence of invasive breast cancer in the presence of competing mortality: the Canadian National Breast Screening Study.

Mortality due to causes other than breast cancer is a potential competing risk which may alter the incidence probability of breast cancer and as such should be taken into account in predictive modelling. We used data from the Canadian National Breast Screening Study (CNBSS), which consist of two randomized controlled trials designed to evaluate the efficacy of mammography among women aged 40-59. The participants in the CNBSS were followed up for incidence of breast cancer and mortality due to breast cancer and other causes; this allowed us to construct a breast cancer risk prediction model while taking into account mortality for the same study population.

Measuring data reliability for preventive services in electronic medical records.

Background: Improvements in the quality of health care services are often measured using data present in medical records. Electronic Medical Records (EMRs) contain potentially valuable new sources of health data. However, data quality in EMRs may not be optimal and should be assessed.

Determining mortality rates attributable to Clostridium difficile infection.

To determine accuracy of measures of deaths attributable to Clostridium difficile infection, we compared 3 measures for 2007-2008 in Ontario, Canada: death certificate; death within 30 days of infection; and panel review. Data on death within 30 days were more feasible than panel review and more accurate than death certificate data.

Implementation of electronic medical records: theory-informed qualitative study.

Implementation of electronic medical records: effect on the provision of preventive services in a pay-for-performance environment.

Objective: To study the effect of electronic medical record (EMR) implementation on preventive services covered by Ontario's pay-for-performance program.

Design: Prospective double-cohort study.

Participants: Twenty-seven community-based family physicians.

Identifying public health competencies relevant to family medicine.

Public health situations faced by family physicians and other primary care practitioners, such as severe acute respiratory syndrome (SARS) and more recently H1N1, have resulted in an increased interest to identify the public health competencies relevant to family medicine. At present there is no agreed-on set of public health competencies delineating the knowledge and skills that family physicians should possess to effectively face diverse public health challenges. Using a multi-staged, iterative process that included a detailed literature review, the authors developed a set of public health competencies relevant to primary care, identifying competencies relevant across four levels, from "post-MD" to "enhanced.

Objective: To assess the concerns of adult patients with spine-related complaints during the period between referral to and consultation with a spine surgeon.

Design: Prospective survey.

Setting: Toronto, Ont.

Effective and cost-effective clinical trial recruitment strategies for postmenopausal women in a community-based, primary care setting.

Introduction: Little evidence exists to guide investigators on the effectiveness and cost-effectiveness of various recruitment strategies in primary care research. The purpose of this study is to describe the effectiveness and cost-effectiveness of eight clinical trial recruitment methods for postmenopausal women in a community-based setting.

Methods: A retrospective analysis of the yield and cost of eight different recruitment methods: 1) family physician (FP) recruiters, 2) FP referrals, 3) community presentations, 4) community events, 5) newsletters, 6) direct mailings, 7) posters, and 8) newspaper advertisements that were used to recruit postmenopausal women to a randomized clinical trial (RCT) evaluating the effectiveness of gabapentin in treating hot flashes.

Canadian medical students' perceptions of public health education in the undergraduate medical curriculum.

Purpose: To understand the perceptions and attitudes of Canadian medical students toward their undergraduate medical public health curriculum and to identify student suggestions and priorities for curriculum change.

Method: Five focus groups of 11 or 12 medical students from all years of medical school were recruited at McMaster University Faculty of Health Sciences, Université de Sherbrooke Faculty of Medicine and Health Sciences, University of Toronto Faculty of Medicine, University of Manitoba Faculty of Medicine, and University of British Columbia Faculty of Medicine between February and April 2006. A professional facilitator was hired to conduct the focus groups using a unique, computer-based facilitation system.
