ABSTRACT

An effective healthcare system should embrace practices that enhance overall quality and productivity. Training primary care physicians in Point-of-Care Ultrasound (POCUS) has become part of the processes that improve the quality of patient care and serve to guide the diagnostic impression quickly and effectively. With the purpose of highlighting the applications and challenges of POCUS use in US primary health care, we conducted a narrative review based on PubMed-indexed and Cochrane Library English text publications searched in May-July 2022 using a combination of key terms including point of care ultrasound, primary care, and US healthcare. Many studies have shown that POCUS has a positive impact on fostering medical attention and reducing morbidity, mortality, and healthcare costs. Besides assisting in procedures, POCUS has a head-to-toe application in evaluating inflammatory and infectious conditions, acute abdomen, cardiopulmonary function, musculoskeletal and vascular pathologies. However, its uniform implementation is limited across the US healthcare system due to multitudes of barriers such as lack of training, resource scarcity, and low reimbursement. Training primary care physicians in general and emergency care providers, in particular, is key to scaleup POCUS use. Large size studies are paramount to further explore the effectiveness of POCUS and identify key challenges to its implementation.

ABSTRACT

Herbal supplements are common complementary and alternative medicine (CAM) approaches with an ever-increasing use trend in the last two decades among the US population. Self-medication with herbal supplements which are promoted for general well-being, weight loss, immunity, and memory boost, and mental and physical health claims are very prevalent. There is a misperception that herbal supplements are harmless as they are prepared from natural sources. Unlike conventional drugs, the US Food and Drug Administration (FDA) does not regulate herbal supplements for premarketing purity and potency. Hence, there is a growing concern for health risks due to misbranded toxic ingredients, contaminants, adulterants, and herb-drug interactions (HDI) with co-administered drugs. The spectrum of pharmacological and toxicological effects of herbal supplements includes deranged lab results, allergic reactions, genotoxicity, carcinogenicity, teratogenicity, organ damage, and even fatality contributing to sizable emergency visits and hospitalizations in the US. The use of herbal supplements should be carefully monitored in high-risk groups such as pediatric and geriatric populations, pregnant women, breastfeeding mothers, immunocompromised patients, and surgical candidates. The deleterious health effects of herbal supplements are loosely addressed in conventional medical practice in part due to the limited knowledge of practitioners. This comprehensive narrative review aims to explore the clinical implications of herbal supplements in order to fill the knowledge gaps by summarizing scientific publications. It also highlights the pivotal roles physicians can play in minimizing the health risks of herbal supplements by encouraging patients to disclose usage through a non-judgmental approach, employing HDI screening tools, and reporting adverse reactions to FDA. Formal training of physicians, a standardized pharmacovigilance system, stricter regulation of the herbal industry, and more scientific studies are keys to establishing herbal safety and efficacy in clinical practice.
