American College of Lifestyle Medicine Expert Consensus Statement: Lifestyle Medicine for Optimal Outcomes in Primary Care

OBJECTIVE

Identify areas of consensus on integrating lifestyle medicine (LM) into primary care to achieve optimal outcomes.

METHODS

Experts in both LM and primary care followed an a priori protocol for developing consensus statements. Using an iterative, online process, panel members expressed levels of agreement with statements, resulting in classification as consensus, near consensus, or no consensus.

RESULTS

The panel identified 124 candidate statements addressing: (1) Integration into Primary Care, (2) Delivery Models, (3) Provider Education, (4) Evidence-base for LM, (5) Vital Signs, (6) Treatment, (7) Resource Referral and Reimbursement, (8) Patient, Family, and Community Involvement; Shared Decision-Making, (9) Social Determinants of Health and Health Equity, and (10) Barriers to LM. After three iterations of an online Delphi survey, statement revisions, and removal of duplicative statements, 65 statements met criteria for consensus, 24 for near consensus, and 35 for no consensus. Consensus was reached on key topics that included LM being recognized as an essential component of primary care in patients of all ages, including LM as a foundational element of health professional education.

CONCLUSION

The practice of LM in primary care can be strengthened by applying these statements to improve quality of care, inform policy, and identify areas for future research.

Lifestyle Medicine: Prevention, Treatment, and Reversal of Disease

Lifestyle medicine (LM) expands the scope of preventive medicine by focusing on the promotion of healthy lifestyles while preventing, treating, and reversing the vast majority of chronic diseases caused by behaviors and environmental factors. LM focuses on six pillars-a plant-predominant eating pattern; physical movement; restorative sleep; management of stress; avoidance of risky substances; and positive social connections. Advances in LM competencies, education, certification, resources, and practice models are accelerating with a particular need and focus on underserved and most seriously impacted patients and communities. A comprehensive and integrated strategy addressing "whole person health" is emerging as a compelling framework for providers and health systems which combines a foundational commitment to prevention with a systematic approach to the actual and root causes of premature disease, disability, and death.

A Career Life-Cycle Perspective on Women's Health and Safety: Insights From the Defense Health Board Report on Military Women's Health

OBJECTIVE

Women's health has demanded more attention from employers as women integrated into the workforce. Traditionally male-dominant fields and occupations require special attention to workplace design, physical standards for entry, employment practices, equipment, and health monitoring. This editorial summarizes the Defense Health Board's (DHB) review of Active Duty Women's Health and its recommendations grounded in a woman's career life-cycle.

METHODS

The DHB reviewed the Department of Defense and foreign militaries' current women's health services, relevant policies and practices, peer-reviewed scientific literature, and subject matter expert interviews.

RESULTS

The DHB's recommendations centered on a comprehensive approach to education, health care access and treatment, professional workforce development, workplace standards and equipment, and accountable outcomes metrics to guide improvement.

CONCLUSIONS

Employers can learn how to reduce morbidity, leading to a healthier and more productive female workforce.

Mobilizing the U.S. Military's TRICARE Program for Value-Based Care: A Report From the Defense Health Board

The U.S. Military Health System spends about $50 billion annually to provide care to 9.6 million active duty service members, retirees, and their families through its TRICARE health plans. TRICARE follows the predominant payment model in the USA-fee-for-service-although the Department of Defense (DoD) and Congress encourage and mandate a move toward alternative payment models-mainly, fee-for-value. For the next TRICARE contracts which will begin in 2023, the DoD asked its health-focused federal advisory committee, the Defense Health Board (DHB), to recommend how best to assess and prioritize leading value-based healthcare initiatives identified from private, public, and employer-based health plans. The November 2020 report, 'Modernization of the TRICARE Benefit', specifies a rubric to evaluate these value-based care initiatives not only in traditional measures of effectiveness but also in terms of the Defense Health Agency's Quadruple Aim with its focus on readiness. The goal of TRICARE's move toward value-based care is to leverage its size and focus on prevention of disease and injury to maintain the readiness of the U.S. Armed Forces in addition to delivering great outcomes and value to the DoD's nearly 10 million beneficiaries. The DHB emphasizes that TRICARE's size and focus on providing quality care at lower cost will incentivize providers to participate in the shift toward value-based care despite the potential challenges in transitioning to this system. This shift also aims to motivate other large government and private payors to accelerate the adoption of value-based care through TRICARE's example.

Prioritized Research for the Prevention, Treatment, and Reversal of Chronic Disease: Recommendations From the Lifestyle Medicine Research Summit

Declining life expectancy and increasing all-cause mortality in the United States have been associated with unhealthy behaviors, socioecological factors, and preventable disease. A growing body of basic science, clinical research, and population health evidence points to the benefits of healthy behaviors, environments and policies to maintain health and prevent, treat, and reverse the root causes of common chronic diseases. Similarly, innovations in research methodologies, standards of evidence, emergence of unique study cohorts, and breakthroughs in data analytics and modeling create new possibilities for producing biomedical knowledge and clinical translation. To understand these advances and inform future directions research, The Lifestyle Medicine Research Summit was convened at the University of Pittsburgh on December 4–5, 2019. The Summit's goal was to review current status and define research priorities in the six core areas of lifestyle medicine: plant-predominant nutrition, physical activity, sleep, stress, addictive behaviors, and positive psychology/social connection. Forty invited subject matter experts (1) reviewed existing knowledge and gaps relating lifestyle behaviors to common chronic diseases, such as cardiovascular disease, diabetes, many cancers, inflammatory- and immune-related disorders and other conditions; and (2) discussed the potential for applying cutting-edge molecular, cellular, epigenetic and emerging science knowledge and computational methodologies, research designs, and study cohorts to accelerate clinical applications across all six domains of lifestyle medicine. Notably, federal health agencies, such as the Department of Defense and Veterans Administration have begun to adopt “whole-person health and performance” models that address these lifestyle and environmental root causes of chronic disease and associated morbidity, mortality, and cost. Recommendations strongly support leveraging emerging research methodologies, systems biology, and computational modeling in order to accelerate effective clinical and population solutions to improve health and reduce societal costs. New and alternative hierarchies of evidence are also be needed in order to assess the quality of evidence and develop evidence-based guidelines on lifestyle medicine. Children and underserved populations were identified as prioritized groups to study. The COVID-19 pandemic, which disproportionately impacts people with chronic diseases that are amenable to effective lifestyle medicine interventions, makes the Summit's findings and recommendations for future research particularly timely and relevant.

Impact of Physician Referral to Health Coaching on Patient Engagement and Health Risks: An Observational Study of UPMC's Prescription for Wellness

PURPOSE

Evaluate impact of physician referral to health coaching on patient engagement and health risk reduction.

DESIGN

Four-year retrospective, observational cohort study with propensity-matched pair comparisons.

SETTING

Integrated delivery and finance system in Pittsburgh, Pennsylvania.

SAMPLE

10 457 adult insured members referred to health coaching by their physician; 37 864 other members identified for health coaching through insurer-initiated outreach.

INTERVENTION

Practice-based, technology-supported workflow and process for physician prescribing of health coaching during regular office visit, with follow-up on patient's progress and implementation supports.

MEASURES

Patient engagement based on completion of pre-enrollment assessment, formal enrollment in health coaching, completion of required sessions, health risk levels, and number of health risks pre- and post-health coaching referral.

ANALYSIS

Difference-in-difference analysis to assess change in health risk levels and number of health risks pre- and post-health coaching and probability weighting to control for potential confounding between groups.

RESULTS

Members referred by a physician were significantly more likely to enroll in a health coaching program (21.0% vs 6.0%, P < .001) and complete the program requirements (8.5% vs 2.7%, P < .001) than when referred by insurer-initiated outreach; significant within group improvement in health risk levels from baseline (P < .001) was observed for both the groups.

CONCLUSIONS

Patients are significantly more likely to engage in health coaching when a referral is made by a physician; engagement in health coaching significantly improves health risk levels.

An Evaluation of Lifestyle Health Coaching Programs Using Trained Health Coaches and Evidence-Based Curricula at 6 Months Over 6 Years

PURPOSE

Describe health plan member-level participation, completion, and 6-month outcomes for 5 lifestyle health coaching programs offered by an integrated delivery and financing system (IDFS) over 6 years.

DESIGN

Case series study of 5 lifestyle programs with 180-day follow-up.

SETTING

Large Western PA integrated delivery and financing system (IDFS) deployed multiple coaching modalities for diverse insurance-member enrolled population.

PARTICIPANTS

A total of 14 591 health plan members choosing a lifestyle health coaching program.

INTERVENTION

Evidence- and curriculum-based lifestyle health coaching programs delivered by 1 of 4 interactive modalities.

MEASURES

A single metric was used as an overall indicator of clinical success for each program. Success measures include a ≥5% reduction of self-reported baseline weight, meeting physical activity guidelines, and 7-day point prevalence abstinence from tobacco. For stress and nutrition, where no single target measure exists, a metric was created that represented a net improvement across all key outcomes measured.

ANALYSIS

The proportion of members meeting target outcomes were calculated and described across all time points and modalities.

RESULTS

At 180 days, 77% of enrolled members reported reduced stress, 7% quit tobacco, 50.5% met physical activity guidelines, 65.2% improved nutrition, and 44.2% lost 5% or more of baseline weight.

CONCLUSION

This evaluation describes the real-world effectiveness of evidence- and curriculum-based lifestyle improvement programs delivered by trained health coaches to a diverse health plan member population.

The Healthy Health Care Workplace: a Competitive Advantage

PURPOSE OF REVIEW

This review provides an evidence-based approach to improve health, reduce excessive medical costs, and optimize productivity for health care employees and their families. What opportunities and challenges are unique or specific to health care organizations particularly as aligned with value and competitive advantage in achieving the Quadruple Aim?

RECENT FINDINGS

An integrated approach to improving health and performance is essential. The strategy includes the employer "environment" (broadly defined), health and medical care behaviors, care delivery modalities, benefits alignment, and a supportive, total health and productivity integrated data analytic capability. Epigenetics and lifestyle medicine represent a promising direction in accelerating the prevention, treatment, and reversal of common chronic disease. An integrated health and productivity approach, emerging science, and practices can accelerate health care systems' goal to improve employee health and organizational competitiveness. Additional published examples of health care specific employer experience will further advance refinement of existing models and tailoring to the medical care setting.

UPMC Prescription for Wellness: A Quality Improvement Case Study for Supporting Patient Engagement and Health Behavior Change

Addressing patient health and care behaviors that underlie much of chronic disease continues to challenge providers, medical practices, health systems, and insurers. Improving health and care as described by the Quadruple Aim requires innovation at the front lines of clinical care: the doctor-patient interaction and office practice. This article describes the use of Lean Six Sigma in a quality improvement (QI) effort to design an effective and scalable method for physicians to prescribe health coaching for healthy behaviors in a primary care medical home within a large integrated delivery and financing system. Building on the national Agency for Healthcare Research and Quality and Robert Wood Johnson Foundation-funded Prescription for Health multisite demonstration, this QI case study provides important lessons for transforming patient-physician-practice support systems to better address lifestyle and care management challenges critical to producing better outcomes.

Competencies for population-based clinical managers. A survey of managed care medical directors

BACKGROUND

The evolution of American health care into integrated systems of delivery and finance requires a specialized set of population-based skills for physicians. The field of preventive medicine represents one source of this expertise. Specific competencies for the emerging area of managerial medicine have not been well delineated.

METHODS

Using concept documents from the Residency Review Committee for Preventive Medicine and the American Board of Preventive Medicine, a list of proposed competencies for managerial medicine was identified. Surveys were mailed to medical directors of all members of the American Association of Health Plans and to a random sample of diplomates of the American Board of Preventive Medicine. Respondents were asked to rate the importance of these competencies for a population-oriented clinician manager.

RESULTS

Areas rated highly by medical directors included health services research (including outcome research), quality assurance and improvement, health risk assessment and reduction, programmatic skills, and clinical preventive skills. Responses from preventive medicine specialists were similar, but placed lower emphasis on these skills.

CONCLUSION

Despite its limited response rate, this survey may be useful in the implementation of specialty training in managerial medicine. Residency training programs may choose to emphasize specific content area that reflect the priorities expressed by physicians actively involved in management.

Performance indicators for assessing competencies of preventive medicine residents

Heightened national interest in population-based medicine, clinical preventive services, and health care management underscores the current need for definition and assessment of physician competency in these areas. This article describes a project sponsored by the Health Resources and Services Administration (HRSA) to develop competencies for each of the three specialty areas in preventive medicine and appropriate measures for the achievement of those competencies. We discuss fundamental issues surrounding assessment that helped guide the process, types of measurement strategies, and criteria for effective competencies and performance indicators. The article also explains the Work Group process used to reach consensus and identifies concerns and challenges raised during this process. We include the list of specialty competencies and performance indicators developed by the project. The project, entitled "Improving Training of Preventive Medicine Residents through the Development and Evaluation of Competencies," served as a model for interorganizational collaboration between the federal government (HRSA); a specialty society, the American College of Preventive Medicine (ACPM); and a preventive medicine residency program, State University of New York (SUNY) at Stony Brook. The commonality of competencies expected of residents in all three specialty areas of preventive medicine--occupational medicine, general preventive medicine and public health, and aerospace medicine--reaffirmed the rationale for including all of these areas within the single specialty of preventive medicine.

Board certification among preventive medicine residency graduates: characteristics, advantages, and barriers

In 1991, a mail survey was conducted of graduates (1979-1989) of general preventive medicine/public health (GPM/PH) residency programs to obtain information about the graduates' demographic characteristics, training, and present professional work. Specifically, we evaluated the survey data for percentage of graduates with board certification, advantages of board certification, and barriers to board certification in preventive medicine (PM). The survey response rate was 74% (797 of 1,070 graduates). Only 45% of the respondents were board certified in PM as of 1991. The percentage of respondents board certified in PM was highest among military PM residency graduates and lowest among those from the Centers for Disease Control (CDC) PM residency. Reasons for not taking the board examination included the perception of limited benefit of board certification in current employment or professional endeavors, previous board certification in a clinical specialty, lack of a master of public health (MPH) degree, high cost and time commitment for the examination, and uncertainty about examination admission requirements. PM residency graduates with board certification in PM were more likely to be involved in public health and preventive medicine programs, devoted more time to administration and management, and earned more income than those PM residency graduates without PM board certification. Increasing the percentage of residency graduates who pursue PM board certification will require increasing the advantages of certification for practice, encouraging all residents to identify themselves as practicing the specialty of PM, and addressing the unique concerns of physicians who train both in PM and in a purely or primarily clinical specialty.

Viral hepatitis in the U.S. Air Force, 1980-89: an epidemiological and serological study

This paper reports the epidemiology of hospital-diagnosed acute viral hepatitis in U.S. Air Force personnel from 1980-89. First hospitalizations for viral hepatitis generally declined, ranging from 24.6 to 47.2 per 100,000 personnel. Hepatitis rates were higher among men, (RR = 1.3; 95% C.I., 1.1-1.5) and higher among blacks, compared to whites (RR = 1.4; 95% C.I., 1.3-1.6). Analysis of risk associated with various occupations demonstrated an increased risk of viral hepatitis for procedurally oriented medical personnel (physicians, clinical nurses, dentists) when compared to all other occupations (RR = 1.5; 95% C.I., 1.1-1.9). Pilots and navigators demonstrated a decreased risk of acute viral hepatitis. Members hospitalized for hepatitis B had a prior or concurrent diagnosis for sexually transmitted disease in 37% of cases; for drug abuse, 32% of cases. Serum samples from 332 individuals demonstrated that hepatitis A had the highest rate of agreement (84%) between serology and hospital discharge diagnosis. Only 3% of individuals with the diagnosis of NANB hepatitis were positive for hepatitis C.

Alcohol-related mortality in the U.S. Air Force, 1990

Alcohol-related morbidity and mortality represent a major public health problem in the United States, particularly among young men. Standardized comparisons of alcohol use have demonstrated that members of the military consume more alcohol than matched civilians. To quantify the impact of alcohol use by active duty members of the Air Force for calendar year 1990, we reviewed 283 death certificates and analyzed the cause of death using the Alcohol-Related Disease Impact (ARDI) computer program. Injuries accounted for 73% of all deaths among active duty Air Force personnel, with motor vehicle accidents (MVAs) accounting for 31% of total mortality. Sixty-six deaths (23%) were attributable to alcohol-related causes and accounted for 2,300 years of potential life lost before 65 years of age. Analysis of blood alcohol levels taken from a subset of active duty deaths resulting from MVAs and suicides yielded alcohol-attributable fractions similar to those obtained by the ARDI method. Periodic assessment and dissemination of alcohol-related mortality statistics in the military using the ARDI methodology represent an important public health education tool.

Health insurance coverage for smoking cessation services

The health benefits from quitting smoking have been well documented; however, most health insurance plans in the United States, both public and private, have excluded coverage of smoking cessation services. Since 1988, numerous public health policy documents have called for health insurance coverage of smoking cessation services, although there is little agreement over what kinds of services or interventions are most appropriate for health insurance coverage. The purposes of this paper are to (1) describe current public policy for health insurance coverage of smoking cessation services; (2) review the current status of policy adoption by private health insurance carriers, health maintenance organizations, self-funded employers, as well as public insurance programs including Medicare and Medicaid; (3) analyze the major barriers faced by health insurers, health care providers and policy makers in offering coverage for smoking cessation services; and (4) outline the specific policy options that the federal government, state governments, employers and anti-smoking coalitions can take to increase insurance coverage for smoking cessation services. The paper concludes with recommendations for practitioners, researchers and policy makers.

Nosocomial Legionnaires' disease: aspiration as a primary mode of disease acquisition

PURPOSE

Nosocomial Legionnaires' disease remains a significant problem with many unresolved questions regarding transmission of legionella organisms to patients. We performed a case-control and environmental study to identify risk factors and modes of transmission of Legionella infection during an outbreak of nosocomial Legionnaires' disease in a military medical center.

PATIENTS AND METHODS

During the calendar year 1989, 14 cases of nosocomial Legionnaires' disease were identified by active surveillance following the discovery of 2 culture-proven cases among organ transplant recipients. Four control patients were matched to each case by age, sex, and date of admission. Cases and controls were compared with respect to past medical history and hospital exposure variables. Odds ratios (ORs) and 95% confidence intervals (CIs) were calculated for matched variables. Environmental culturing of air and water supplies in and around the medical center was also performed.

RESULTS

The case-control study revealed the following significant risk factors for the acquisition of nosocomial Legionnaires' disease: immunosuppressive therapy (OR = 32.7, CI = 4.5 to 302.6), nasogastric tube use (OR = 18.4, CI = 2.6 to 166.2), bedbathing (OR = 10.7, CI = 2.2 to 59.0), and antibiotic therapy (OR = 14.6, CI = 2.9 to 84.4). Shower use (OR = 0.1, CI = 0 to 0.4) appeared to be a negative risk factor. Water cultures revealed Legionella pneumophila serogroup 1, monoclonal antibody subtype Philadelphia (identical to all patient isolates) in the ground-water supply to the hospital, 1 hot-water tank, and 15% of 85 potable water sites tested. Air sampling of cooling towers, hospital air intakes, and medical air and oxygen supplies were negative for Legionella organisms.

CONCLUSIONS

This study confirms the importance of potable water in transmitting nosocomial Legionnaires' disease and suggests that the organism gains access to the hospital via external water supplies. The risk factors identified in this case-control study provide evidence that Legionnaires' disease may act as a superinfection in a nosocomial setting and is likely acquired by aspiration, similar to other nosocomial pneumonias.

Viral hepatitis in the US Air Force, 1980-1989

Viral hepatitis and its acute and chronic complications continue to pose significant threats to the readiness of military personnel. Knowledge about the specific viral agents and their routes of transmission are important in developing prevention strategies. A recent analysis of hepatitis in the US Navy for the period 1975-1984 is reviewed. In order to better characterize the risk of viral hepatitis among US Air Force personnel, a comprehensive review of inpatient and quarters data for hepatitis A, B and 'non-A, non-B' were reviewed from Air Force medical treatment facilities worldwide for the period 1980-1989. Following a discussion of the study methodology, preliminary data and hepatitis type-specific demographic risk variables are discussed. Preliminary results from a hepatitis serosurvey (A, B and C antibody with use of a supplemental validating assay) of the subset of the study cohort who are currently on active duty are briefly reviewed.

Preventive medicine residents: a national survey

Little is known about those physicians who pursue graduate medical education in preventive medicine, including aerospace medicine, general preventive medicine and public health, and occupational medicine. We surveyed resident physicians about their academic background, financial environment, clinical activities, and professional goals. A total of 147 residents (30%) responded from a population of 498 residents. The data suggest a lack of available information about preventive medicine training and careers among medical students who subsequently pursue such training. Their economic environment is extremely diverse, with a wide range of salary, "moonlighting" hours, educational loans, and service obligations. Although the median annual salary ($24,700) is similar to the national average resident salary, 32% of respondents earned less than $20,000, and 95% have educational debts averaging $30,900. Sixty-two percent of respondents perform clinical work in their residency, whereas 76% desire future clinical work as part of their practice. This gap is most pronounced in general preventive medicine and public health. The residents express a wide range of interests in future practice of preventive medicine; 54% are interested in government work, and 33% desire academic careers.

The epidemiology of tuberculosis in the U.S. Air Force, 1987

In preparation for a major revision of the Air Force tuberculosis (TB) prevention and control program, we reviewed tuberculosis cases treated at Air Force hospitals and the U.S. Air Force tuberculin skin testing program for 1987. The highest rates of active TB cases and infection were observed in the Pacific overseas region. Active tuberculosis cases occurred most frequently in white male retirees and in Asian dependent females. Nineteen cases (9% of total TB cases) occurred in children under the age of 5. Only 46-60% of individuals with a positive Purified Protein Derivative-Tuberculin were placed on isoniazid (INH) chemoprophylaxis. Flying status personnel were less likely to have either active disease or TB infection than non-flying active duty members. Based upon these findings, Air Force tuberculosis prevention and control program efforts should de-emphasize screening of low risk active duty populations and stress timely reporting and case finding, compliance with therapy, and initiation of INH chemoprophylaxis in accordance with existing guidelines. Young children who are contacts of active TB cases should receive special emphasis.
