Focus: Preventive Medicine: 2020 Evaluation of Portable Vision Screening Instruments

Amblyopia is the most common cause of preventable visual impairment in children and occurs as a result of unilateral or bilateral impairment in best-corrected visual acuity. Early diagnosis and proper treatment are crucial to prevent poor visual outcomes in adulthood. Advances in technology have provided more objective diagnostic tools, which can now be used by a wide range of healthcare providers. Here, we highlight tools that have gained popularity in the past two decades and compare clinically relevant parameters to guide primary care providers seeking to incorporate instrumental vision screening in pediatric patient care.     

Focus: Preventive Medicine: Race,Racism, and the Policy of 21st Century Medicine

This perspective describes three new policies passed at the November 2020 Special Meeting of the American Medical Association House of Delegates. These policies (1) denounce racism as a public health threat; (2) call for the elimination of race as a proxy for ancestry, genetics, and biology in medical education, research, and clinical practice; and (3) decry racial essentialism in medicine. We also explore the social and institutional context leading to the passage of these policies, which speak directly to the harmful legacy of racism in America, and its insidious impact on the healthcare system.     

Focus: Preventive Medicine: Postpartum Depression and Quality of Life: A Path Analysis

Purpose: The aim of this study was to model the relationship between risk factors of postpartum depression and quality of life in Iranian women. Methods: In this study, 306 women were included as a sample. The study tools of the Edinburgh Postpartum Depression Inventory included items such as socioeconomic characteristics, recent pregnancy history and outcome, and Quality of Life Questionnaire (SF-12). SPSS software was used for data analysis and a significance value of 0.05 was considered. Results: Most participants were homemakers with no instances of abortion, no stillbirth, no history of depression, no preterm delivery, no difficulties during pregnancy, no difficulties during delivery, no unplanned pregnancy, no smoking during pregnancy, had family support during pregnancy and after delivery, type of delivery was cesarean, had a healthy baby and satisfaction with neonatal sex, and never or rarely experienced partner violence. Their mean age, years of education, living arrangements, and breastfeeding of participants respectively were 29.73±5.42, 14.64±1.96, 1.09±0.53, and 5.61±2.98. The prevalence of postpartum depression was 5.6%. According to the path analysis, living arrangements with β=0.73 had the most direct effect and occupation with β=0.69 had the most indirect effect on postpartum depression. Conclusions: According to the path analysis model, postpartum depression is affected by many factors such as age, years of education, occupation, living arrangements, and quality of life.     

Focus: Preventive Medicine: Patient Safety Functions of State Medical Boards in the United States

The state medical board system in the United States plays a crucial role in promoting patient safety and is a primary vessel through which policymakers are able to regulate healthcare. The system’s origins, and how it has evolved in tandem with the practice of medicine generally, have heavily shaped its current structure and scope of activities. In particular, the ethos of a largely self-regulated profession has corresponded to a heavy physician influence. In light of this influence, maintaining legitimacy continues to require careful efforts by the state boards to avoid any perceived professional protectionism.     

Focus: Preventive Medicine: Before the Bullets Fly: The Physician’s Role in Preventing Firearm Injury

Firearm injury is a disease that is disproportionately prevalent in the United States. When a bullet hits a human being, it brings together multiple structural determinants of health into one acute, life-changing event. Firearm injury can lead to long-term mental and physical challenges for individuals, families, and communities. Despite the impact of this disease, physicians often underestimate their role in not only treating but also preventing firearm injury. Physicians can intervene through screening, counseling, community engagement, and advocacy, and can mobilize the health care systems they serve to engage with injury prevention. Physicians also play a key role in expanding the knowledge base on firearm injury through much-needed research on the epidemiology, context, and outcomes of firearm injury. When we treat firearm injury as a disease, we can develop and implement interventions from the clinic to the statehouse that can curb profound harms. This work and these opportunities belong not only to emergency physicians and trauma surgeons, but to all fields that evaluate and assess patients over the life course.     

Focus: Preventive Medicine: Leveraging Organizational Health Literacy to Enhance Health Promotion and Risk Prevention: A Narrative and Interpretive Literature Review

Organizational health literacy involves the health care organizations’ ability to establish an empowering and co-creating relationship with patients, engaging them in the design and delivery of health services in collaboration with health professionals. Although scholars agree that organizational health literacy contributes to health promotion and risk prevention via patient empowerment, literature is not consistent in depicting the interplay between organizational health literacy and preventive medicine. The article intends to shed light into this issue, summarizing current knowledge about this topic and advancing avenues for further development. A narrative literature review was performed through a systematic search on PubMed^®, Scopus^®, and Web of Science^™. The review focused on 50 relevant contributions. Organizational health literacy triggers the transition towards a patient-centered approach to care. It complements individual health literacy, enabling patients to actively participate in health promotion and risk prevention as co-producers of health services and co-creators of value. However, many obstacles – including lack of time and limited resources available – prevent the transition towards health literate health care organizations. Two initiatives are required to overcome extant barriers. On the one hand, a health literate workforce should be prepared to increase the institutional ability of health care organizations to empower and engage patients in health co-creation. On the other hand, increased efforts should be made to assess organizational health literacy and to make its contribution to preventive medicine explicit.     

Focus: Preventive Medicine: Exophytic External Occipital Protuberance Prevalence Pre- and Post-iPhone Introduction: A Retrospective Cohort

Introduction: In controversial fashion, the presence of an enlarged external occipital protuberance has been recently linked to excessive use of handheld electronic devices. We sought to determine the prevalence of this protuberance in a diverse age group of adults from two separate time periods, before and approximately 10 years after the release of the iPhone, to further characterize this theory, as if indeed valid, such a relationship could direct preventative behavior. Materials and Methods: Eighty-two cervical spine radiographs between March 7, 2007 through June 29, 2007 and 147 cervical spine radiographs between October 25, 2017 through January 1, 2018 were reviewed for the presence or absence of an exophytic external occipital protuberance. Influence of sex and age were also assessed. Results: There were 41/82 (50%) patients within the 2007 pre-iPhone group with an exophytic external occipital protuberance, ranging from 2.7-33.8 mm in length. Twenty-seven out of 82 (32.9%) had an external occipital protuberance at or above 10 mm. There were 49/147 (33.3%) patients within the 2017 post-iPhone group with an exophytic external occipital protuberance, ranging from 4.4-53.8 mm in length. Thirty-three out of 147 (22.4%) had an external occipital protuberance at or above 10 mm. When considering accessibility to the iPhone, sex, and age to the presence of an exophytic external occipital protuberance, only sex has a statistically significant association, p=0.000000033. Conclusion: We found no significant association with iPhone accessibility and an exophytic external occipital protuberance. Due to inherent limitations in the retrospective nature of the study, future research is needed to better examine the association of handheld electronic devices with exophytic external occipital protuberances.     

Focus: Preventive Medicine: Undiagnosed Hypertension and Undiagnosed Type 2 Diabetes among Overweight and Obese Marshallese Participants in a Diabetes Prevention Program

Hypertension and type 2 diabetes (T2D) are major public health issues that disproportionately affect minority communities, including Native Hawaiians and Pacific Islanders (NHPI). Minority communities are also more likely to have undiagnosed hypertension and T2D. Marshallese Pacific Islanders have been shown to have high proportions of diagnosed and undiagnosed hypertension and T2D. Using survey and biometric data collected from 378 overweight/obese Marshallese Pacific Islander adults, this study documents the prevalence of hypertension and T2D, as well as the prevalence of undiagnosed hypertension and T2D. The study also examines associations between undiagnosed hypertension and undiagnosed T2D and age group, sex, health care access (defined by foregone care due to cost and health insurance status), and body mass index (BMI). Among participants with blood pressure readings indicative of hypertension, 68.4% were undiagnosed, and among participants with HbA1c indicative of T2D, 31.6% were undiagnosed. A quarter of participants (24.5%) had blood pressure and HbA1c measures indicative of both undiagnosed hypertension and undiagnosed T2D. Undiagnosed hypertension was significantly associated with age group (p’s<0.0001) and sex (p=0.028). Undiagnosed T2D was significantly associated with age group (p’s<0.05), forgone care due to cost (p=0.018), health insurance status (p=0.035), and BMI (p=0.001). Participants in this study had high proportions of undiagnosed hypertension and undiagnosed T2D. These findings will be immediately useful for those working to address hypertension and T2D disparities among Marshallese and other NHPI populations.     

Focus: Preventive Medicine: Firearm Injury Among Children and Adolescents in Nigerian Civilian Trauma Setting: Prevalence,Pattern, and Implications for Prevention

Firearm injury in children and adolescents and the morbidity associated with it is an appreciable burden in resource-limited settings, though it is under-reported. This study aimed to determine its prevalence and pattern in Nigerian civilian trauma setting. We undertook a retrospective study of all the patients with firearm injury aged 19 years or under who visited the Emergency Department (ED) of two tertiary hospitals in Nigeria over a period of 15 years. Of the 46,734 children and adolescents seen in the ED, firearm injury was the reason for the visit in 56 of them, giving a prevalence of 1.2 per 1000 ED attendance (95% CI: 0.9-1.6). The male-to-female ratio was 1.8:1, and the mean age was 13.98 ± 5.6 years. The preponderance of firearm injury was in the rural areas, during the dry season, at home, and in the daytime. Armed robbery (20, 35.7%) and communal clash (7, 12.5%) were the two topmost incidents leading to gunshot wounds. Armed robbery-related gunshot occurred mostly on the roads and at nighttime and involved predominantly 15-19-year-olds. Lower extremity was the topmost anatomical region involved. The majority (67%) had no pre-hospital care; the mean and median injury-hospital arrival interval respectively was 352 hrs and 4.2 hrs. Wound infection was the topmost complication. The mean hospital length of stay was 22.6 days. One (1.8%) of the patients died on the third day of hospital admission. Educational campaigns for prevention intensified during the dry season should highlight the risk of firearm injury to this age group and emphasize the importance of proper supervision and guidance of vulnerable children and adolescents. Improving the rates of pre-hospital care and early presentation of victims to the hospital should be considered in tertiary injury prevention strategies.     

Focus: Preventive Medicine: Assessing the Social Influences,Self-Esteem,and Stress of High School Students Who Vape

Adolescent vaping is rapidly rising in Canada, and e-cigarettes have become the most widely used tobacco product among high school students; 29% of students in grades 10 to 12 reported e-cigarette use in 2019. Vaping among adolescents is a problem because the long-term health consequences of e-cigarettes remain unknown, large numbers of teens are becoming addicted to the harmful drug nicotine, and vaping has been shown to increase risk of initiation of combustible tobacco product use. To address the gaps in the current understanding of adolescent e-cigarette use, this study aims to examine the role of social peer and family influence, self-esteem, and stress on teen vaping. Seventy-nine students in grades 10 to 12 at an independent, co-ed high school in Toronto, Ontario completed an online survey about factors that influence them to vape, and about their perceived self-esteem and stress. Survey data was analyzed using Chi-Square tests and T-tests. Common motivations for vaping included stress relief (70%) and peer influence (60%). Family history of smoking or vaping and the ability to vape indoors also influenced vaping habits. Notably, e-cigarette users reported higher stress levels than non-users, but self-esteem levels were comparable. Our findings suggest that high school vaping prevention strategies should focus on stress reduction and encourage healthy coping strategies. Similar research studies should be conducted in other high schools, and future research should further explore the correlation between stress and adolescent vaping.     

Focus: Preventive Medicine: Pre-Participation Screening of Athletes: Primary Health Care Physicians’ Knowledge,Experience, and Approach in Turkey

Pre-participation screening (PPS) is crucial for assessing the competitive athletes since their risk of sudden death is higher than non-athletes. In Turkey, PPS is performed at the primary health care setting by primary care physicians (PCPs) who are family medicine specialists (FMSs) or general practitioners (GPs). Although there are national guidelines, there is no legal regulation for this process. This study aims to evaluate PCPs’ knowledge, experience, and approach about PPS. We prepared an online survey for PCPs and used non-probabilistic sampling. PPS attitudes and practices were analyzed and compared according to factors such as experience, education, and being GP or FMS. Of the 214 PCPs included in the study, 39.3% were female. The mean age was 44.9 years (SD:8.88). The average work experience was 7.9 years. Most participants were aware of their authorization to perform PPS (89.7%) and had previously prepared it (90.2%). However, 6.5% of them felt confident in performing PPS. Only 13.1% were aware of the guidelines. Almost 25% of the participants stated being informed about the subject at some part of their career, but this did not affect the confidence or referral decisions. In addition to medical history and physical examination, further testing was considered necessary by 96.3% of the participants. Significantly more tests were ordered by GPs than FMSs (p=0.026 and p=0.011, respectively). The accurate referral decision ratio was 59.3%, without difference between FMSs and GPs (p=0.216). We found that awareness of the guidelines was low among PCPs who lack confidence in PPS. These factors collectively increased the tendency for unnecessary further testing and referral. Therefore, the PPS implementation into medical school and residency curriculums and national legal regulation for the process is a necessity in Turkey.
