Sample Answer
The United States healthcare system is unique among developed countries in that it is a largely private system. This means that most Americans get their health insurance through their employers, and the government plays a relatively limited role in providing health insurance or healthcare services.
In contrast, most other developed countries have universal healthcare systems, in which the government provides health insurance to all citizens. This means that everyone has access to healthcare, regardless of their income or employment status.
The U.S. healthcare system is also more expensive than other developed countries. In 2020, the United States spent $11,582 per person on healthcare, compared to an average of $4,940 per person in other developed countries.

The EBM âLevels of Evidenceâ are a way of grading the quality of research evidence. The levels are based on the study design, the size of the study, and the consistency of the findings. The levels of evidence are as follows:
- Level I:Â Evidence from systematic reviews of randomized controlled trials.
- Level II:Â Evidence from randomized controlled trials.
- Level III:Â Evidence from well-designed controlled trials without randomization.
- Level IV:Â Evidence from well-designed cohort or case-control studies.
- Level V:Â Evidence from case series or case reports.
- Level VI:Â Expert opinion.
The case âConstraints of the ACA on Evidence-Based Medicineâ discusses the challenges of implementing EBM in the context of the Affordable Care Act (ACA). The ACA requires health plans to cover preventive services that are recommended by the U.S. Preventive Services Task Force (USPSTF). However, the USPSTF does not always have enough evidence to make clear recommendations. This can make it difficult for health plans to know which preventive services to cover.
The case also discusses the role of patient preferences in EBM. The ACA requires health plans to give patients the option to decline preventive services that are recommended by the USPSTF. This can make it difficult for providers to use EBM in their clinical practice, as they may be unsure of what patients want.
The policy of EBM is to use the best available evidence to make decisions about healthcare. This evidence can come from research studies, clinical practice guidelines, and the experience of experts. EBM is important because it can help to improve the quality of healthcare and to reduce the risk of harm.
In conclusion, EBM is a complex process that involves many different players. It is important to consider all of the relevant factors, including the quality of the evidence, the patient’s preferences, and the cost of care, when making decisions about healthcare.
