MACRA likely to accelerate consolidation; will the regulatory framework support it?
Summary
The Medicare sustainable growth-rate formula, a complex payment system, was repealed after 17 years. It was replaced by the Medicare Access and CHIP Reauthorization Act in 2015.
Area of Science:
- Health Policy
- Medical Economics
Background:
- The sustainable growth-rate (SGR) formula was a flawed Medicare physician payment mechanism.
- Legislative efforts to reform SGR spanned nearly two decades.
Purpose of the Study:
- To document the legislative history and eventual repeal of the SGR formula.
- To highlight the transition to the Medicare Access and CHIP Reauthorization Act (MACRA).
Main Methods:
- Legislative analysis of congressional acts related to Medicare physician payment.
- Chronological review of policy changes from 1997 to 2015.
Main Results:
- The SGR formula, established in 1997, underwent numerous legislative modifications.
- The Medicare Access and CHIP Reauthorization Act (MACRA) finally repealed the SGR in April 2015.
Conclusions:
- The repeal of the SGR formula marked a significant shift in Medicare payment policy.
- MACRA introduced a new framework for physician reimbursement, emphasizing value-based care.

Cis-regulatory Sequences
11.8K
Cis-regulatory sequences are short fragments of non-coding DNA that are present on the same chromosomes as the genes that they regulate. These fragments serve as binding sites for transcriptional regulators, proteins that are responsible for controlling gene transcription and differential gene expression across cell types in eukaryotes. Cis-regulatory sequences can be close to the gene of interest or thousands of bases away in the DNA sequence; however, those sequences that are further away are...

Accelerators
288
Accelerators in concrete serve as admixtures to speed up the hardening process, enabling the concrete to achieve early strength faster. Although accelerators do not necessarily impact the time it takes concrete to set, they reduce this time in practice. A common accelerator is calcium chloride, which is particularly useful for hastening early strength development in cold weather or for rapid repair jobs that require quick heat generation after mixing.

Self-Help Support Groups
355
Self-help support groups are voluntary, community-based organizations that provide a platform for individuals with shared concerns to exchange support, insights, and practical strategies for coping with life challenges. Typically led by group members or paraprofessionals, these groups form a cornerstone of mental health care, especially in reaching populations that are underserved by traditional healthcare systems.

Average Acceleration
13.7K
The importance of understanding acceleration spans our day-to-day experiences, as well as the vast reaches of outer space and the tiny world of subatomic physics. In everyday conversation, to accelerate means to speed up. For instance, we are familiar with the acceleration of our car; the harder we apply our foot to the gas pedal, the faster we accelerate. The greater the acceleration, the greater the change in velocity over a given time. Acceleration is widely seen in experimental physics. In...

Instantaneous Acceleration
23.1K
Acceleration is in the direction of the change in velocity, but it is not always in the direction of motion. When an object slows down, its acceleration is opposite to the direction of its motion. Although commonly referred to as deceleration, this causes confusion in our analysis as deceleration is not a vector, and does not point to a specific direction with respect to a coordinate system. Therefore, the term deceleration is not used. For example, when a subway train slows down, it...
