Some favorable data on the Affordable Care Act which came out before today’s news of another Republican court victory in their ongoing efforts to deny people the benefits of Obamacare: [icopyright one button toolbar]
The New England Journal of Medicine has reviewed the increase in coverage under the Affordable Care Act and concluded:
Taking all existing coverage expansions together, we estimate that 20 million Americans have gained coverage as of May 1 under the ACA (Figure 3Figure 3Categories of Expanded Health Insurance Coverage under the Affordable Care Act (ACA).). We do not know yet exactly how many of these people were previously uninsured, but it seems certain that many were. Recent national surveys seem to confirm this presumption. The CBO projects that the law will decrease the number of uninsured people by 12 million this year and by 26 million by 2017. Early polling data from Gallup, RAND, and the Urban Institute indicate that the number of uninsured people may have already declined by 5 million to 9 million and that the proportion of U.S. adults lacking insurance has fallen from 18% in the third quarter of 2013 to 13.4% in May 2014.
However, these surveys may underestimate total gains, since some were fielded before the late March enrollment surge and do not include children. With continuing enrollment through individual marketplaces, Medicaid, and SHOP, the numbers of Americans gaining insurance for the first time — or insurance that is better in quality or more affordable than their previous policy — will total in the many tens of millions.
As we look to the future of the coverage provisions of the ACA and their effect on the U.S. health care system, several observations seem justified. First, as the number of individuals benefiting from the law grows, its wholesale repeal will grow less likely, although the law could still be importantly modified in the future.
Second, experience with the ACA will vary enormously among states. Those deciding not to expand Medicaid will benefit far less from the law, and since many of these states have high rates of uninsured residents and lower health status, the ACA may have the paradoxical effect of increasing disparities across regions, even as it reduces disparities between previously insured and uninsured Americans as a whole.17
Third, the sustainability of the coverage expansions will depend to a great extent on the ability to control the overall costs of care in the United States. Otherwise, premiums will become increasingly unaffordable for consumers, employers, and the federal government. Insurers who seek to control those costs through increasingly narrow provider networks across all U.S. insurance markets may ultimately leave Americans less satisfied with their health care. Developing and spreading innovative approaches to health care delivery that provide greater quality at lower cost is the next great challenge facing the nation.

There has been concern that the increase in number of insured might lead to an increase in number of people seeing physicians despite predictions and early evidence that this would not be a significant problem in most areas. I have seen several reports indicating that doctors generally are not seeing more patients as a result of the Affordable Care Act. The most recent came from Athena Health and the Robert Wood Johnson Foundation. Here is a summary of their findings:
- Influx in New Patient Volume Not Detected: In the first five months of 2014, a national sample of 14,300 health care providers across the athenahealth network did not see an increase in new patient volume.* Instead, the percentage of total visits with new patients actually dropped slightly compared to the same period in 2013. These findings suggest that an increase in newly insured patients, resulting from the ACA, has yet to have an impact on new patient volume at medical practices.
- Health Care Reform Widening the Medicaid Gap: In states that are expanding Medicaid coverage under the ACA, the data shows an overall increase in adult (18-64) Medicaid beneficiary patient visits. In expansion states, on average, the percentage of Medicaid-covered patients who are being seen by primary care physicians is rising, with Medicaid patients accounting for 12.3% of care in December of 2013 compared with an increased rate of 15.6% in May 2014. Surgeons and other specialists also show increases. Conversely, states that are not expanding Medicaid coverage have seen Medicaid visits remaining flat. These findings indicate that the implementation of the ACA is widening the gap of the total share of Medicaid patients that doctors in expansion vs. non-expansion states are caring for.
- No Increase in Chronic Disease Diagnoses Among New Patients: Findings from the first five months of 2014 indicate that established patients have a higher rate of chronic diseases compared with new patients seeking care. When comparing diagnosis rates of chronic conditions from the first five months of 2013 to the first five months of 2014, across both new and established patients, no increase in diagnosis rates of chronic conditions is detected for either population.
It is possible that some of the newly insured are initially going to the Emergency Room and therefore are not picked up as an increase in visits by primary care physicians. In May I reported on a study by the American College of Emergency Physicians which found that 37 percent of ER physicians reported that patient volume had increased slightly, 9 percent reported that it had increased greatly, and 27 percent reported that the number of ER visits had remained the same.
It is also a good finding that the newly insured are not turning out to be sicker than the previously insured. Many insurance companies held off on entering the exchanges last year out of fear that they might wind up with sicker patients, costing them more money. Those which sold coverage have wound up doing well with more insurance companies planning to enter the exchanges to sell coverage for next year. This should help reduce anticipated increases in premiums and give consumers more choice.
