Largest Pediatric Study Shows Obesity Increases Asthma Risk in Children

Largest Pediatric Study Shows Obesity Increases Asthma Risk in Children

ORLANDO – Ten percent of pediatric asthma cases could be avoided if childhood obesity were eliminated, according to research led by Nemours Children’s Health System. The research, published in Pediatrics, the journal of the American Academy of Pediatrics, reported on the analysis of medical records of more than 500,000 children. The study is among the first to use the resources of PEDSnet, a multi-specialty network that conducts observational research and clinical trials across eight of the nation’s largest children’s health systems. PEDSnet is funded by the Patient-Centered Outcomes Research Institute (PCORI), a government-supported nonprofit.

“Pediatric asthma is among the most prevalent childhood conditions and comes at a high cost to patients, families and the greater health system. There are few preventable risk factors to reduce the incidence of asthma, but our data show that reducing the onset of childhood obesity could significantly lower the public health burden of asthma,” said Terri Finkel, M.D., PhD, Chief Scientific Officer at Nemours Children’s Hospital in Orlando and one of three Nemours researchers participating in the study. “Addressing childhood obesity should be a priority to help improve the quality of life of children and help reduce pediatric asthma.”

In this retrospective cohort study design, researchers reviewed de-identified data of patients ages two to 17 without a history of asthma, receiving care from six pediatric academic medical centers between 2009 and 2015. Overweight or obese patients were matched with normal weight patients of the same age, gender, race, ethnicity, insurance type, and location of care. The study included data from 507,496 children and 19,581,972 encounters.

In their analysis, the researchers found that the incidence of an asthma diagnosis among children with obesity was significantly higher than in children in a normal weight range and that 23 to 27 percent of new asthma cases in children with obesity are directly attributable to obesity. Additionally, obesity among children with asthma appears to increase disease severity. Being overweight was identified as a modest risk factor for asthma, and the association was diminished when the most stringent definition of asthma was used. Other significant risk factors of an asthma diagnosis included male sex, age of under 5 years old, African-American race, public insurance.

With 6 to 8 million cases of pediatric asthma previously reported in the United States, the study’s data suggest that 1 million cases of asthma in children might be directly attributable to overweight and obesity and that at least 10 percent of all U.S. cases of pediatric asthma might be avoided in the absence of childhood overweight and obesity.

“This is the first study of its kind, looking at obesity and the risk of developing asthma entirely in a pediatric population, and is made possible through the PEDSnet data collaboration,” said Finkel. “The PEDSnet collaboration brings the power of Big Data to pediatric research and medicine – as well as the expertise to structure the data and understand how to extract the most meaningful points.”

Several limitations of the study are noted, including the retrospective design using electronic health data, which prevent the researchers from drawing absolute conclusions regarding the causal nature of the association between obesity and asthma. Additionally, while the study includes data from a large, geographically diverse population of children, rural children may be underrepresented in the study results.

The research team hopes in the future to use PEDSnet’s capabilities to continue to gain new epidemiologic insights into the relationship between pediatric obesity and asthma, including measures of lung function, comorbidity, and medication data. Each PEDSnet member institution is able to map its own data onto the common data model, creating an enormous resource across the network with the power to produce findings relatively quickly.

Patients, Doctors Dissatisfied with Electronic Health Records

Patients, Doctors Dissatisfied with Electronic Health Records

Electronic Health Records are intended to streamline and improve access to information — and have been shown to improve quality of care — but a new study shows they also leave both doctors and patients unsatisfied, even after full implementation.

The study, by researchers at Lehigh University and the Lehigh Valley Health Network, surveyed physicians, mid-level providers and non-clinical staff at ob-gyn practices where EHRs were installed and analyzed survey answers given by patients. While there have been studies looking at how EHR implementation affects provider and patient satisfaction, this is the first study of how the integration of outpatient and hospital EHR systems affects provider and patient satisfaction.

Published in the August print issues Journal of the American Medical Informatics Association, the study tracked two ob-gyn practices and a regional hospital from 2009 to 2013, during the implementation of an EHR system and its subsequent integration with the hospital system. The EHR was installed in 2009 and information began flowing from the hospital to the ob-gyn practices in mid-2011. Full two-way exchange of clinical information was achieved a year later.

Ob-gyn practices posed a good opportunity for study because typically a woman will see physicians at her ob-gyn practice multiple times during the pregnancy before being admitted for labor (often seeing different doctors), and on average will have at least one pregnancy-related hospital visit prior to giving birth at a hospital, co-author Chad Meyerhoefer, professor of economics at Lehigh University, said.

Previous to the integrated EHR — digital versions of patient medical records were accessible through computers for some patients and paper records were sent by courier to the hospital for others — transmission of such records often was not made between hospitals and outpatient practices in a timely manner. This meant physicians at the practices might not know about visits to the hospital or test results ordered there and hospital doctors would not have access to the woman’s prior clinical data from outpatient OB-GYN appointments during visits to the hospital’s perinatal triage unit.

“We wanted to study how the EHR affected information flow between hospitals and practices and we chose pregnancy and obstetrics because it is a well-defined period — the prenatal care, birth and post-natal care all occur in a time frame we can capture,” said Meyerhoefer, who co-authored the paper with Susan A. Sherer, Mary E. Deily, Shin-Yi Chou and Jie Chen of Lehigh University and Michael Sheinberg and Donald Levick of Lehigh Valley Health Network. “In pregnancy, information is very important, having information about the patient’s prenatal experience can help to avert adverse events during the birth.”

Surprising Results

Researchers discovered both unsurprising and surprising results.

In theory, while it is understandable that implementation of an EHR would be seen as disruptive initially, by the time the EHR was in regular use, one would expect patients and doctors to report improvements in communication and coordination of care. However, the study showed that even after the EHR was established, both doctors and patients expressed dissatisfaction.

In the early stages, doctors and staff expressed frustration at learning a new system and the time it took to enter information. By the end of the study, staff appreciated ease with retrieving information and doctors felt communication and care were improved. Doctors, however, were also less satisfied by the system overall, citing the time it took to enter data, changes to workflow and decreased productivity.

“It was more of an adjustment for physicians, as it required them to do additional documentation they didn’t have to do before, and it had a bigger impact on their workflow,” Meyerhoefer said.

Patients felt the disruption at the beginning, and continued to feel less satisfied with their experiences after the EHR was fully implemented and was being used.

“Our thought was after the system was implemented and some time had passed and all these new capabilities are added to the system, the patients would see the benefits of that and feel better about their visits,” Meyerhoefer said. “But that didn’t happen.”

Why? Researchers aren’t sure, but one aspect may be that patients would likely have been unaware of improvements to their care and outcomes as a result of the EHR and may not have considered that when describing satisfaction levels, Meyerhoefer said. A previous study by the researchers, which looked at data flow from outpatient ob-gyns to the hospital and back and which information mattered, showed that implementation of an EHR decreased adverse birth events and had a positive effect on birth outcomes.

Changes in administrative practices, documentation, staffing, staff work roles and stress, and doctors’ concerns about productivity goals related to the implementation may also have changed the patient experience, or a patient’s perception of the care experience, in ways patients didn’t like.

“It could also be the case that having the computer documentation be a bigger part of patient interactions may be a negative thing for patients,” Meyerhoefer said. “The need for documentation sometimes takes the focus away from having a personal relationship with the patient.”

Training for Doctors

“The takeaway message is that during these implementations or after you have the system in place, you have to really think about how this is going to affect patients and maybe do training on patient interactions with electronic medical records to head off some of these negative effects,” Meyerhoefer said. This might include training for doctors in how to maintain verbal and nonverbal communication with patients during visits while also collecting or inputting information into a computer.

Also, since the brunt of documentation impact falls to physicians and impacts productivity, adjustments should be made to productivity targets that take that into consideration, researchers said.

In addition to patient experiences, the impacts are important to study and consider because installation of an EHR generally changes the way doctors and staff record and report information, as well as work processes and staffing related to documentation. “It can be a big change, and can be very disruptive,” Meyerhoefer said. Acquiring EHR software is typically a large financial investment for a hospital or health system as well. And even after a system is acquired and used, replacing it with a new system would engender similar adoption issues.

“These findings are specific to OB-GYN patients, but I think these results on satisfaction would carry over to many other types of care, where physicians and other clinical providers will not really see the benefit of a system until the information flow is improved, and there can be persistent negative effects on patient satisfaction,” Meyerhoefer said.

Research: Physician Shortage Likely to Have Severe Impact on Patient Care

Research: Physician Shortage Likely to Have Severe Impact on Patient Care

The United States continues to face a projected physician shortage over the next decade, creating a real risk to patient care, according to new data released by the Association of American Medical Colleges. The latest projections continue to align with previous estimates, showing a projected shortage of between 40,800 and 104,900 doctors.

For the third consecutive year, the Life Science division of the global information company, IHS Markit, conducted a study of physician supply and demand on behalf of the AAMC, modeling a wide range of health care and policy scenarios, such as payment and delivery reform, increased use of advanced practice nurses and physician assistants, and delays in physician retirements. This year’s report extended the date of the projections by five years, from 2025 to 2030, to account for the time needed to train a physician who would start medical school in 2017. The report also includes an expanded section modeling the additional demand for physicians that would be generated by health care utilization equity.

“The nation continues to face a significant physician shortage. As our patient population continues to grow and age, we must begin to train more doctors if we wish to meet the health care needs of all Americans,” said AAMC President and CEO Darrell G. Kirch, M.D.

The report aggregates the shortages in four broad categories: primary care, medical specialties, surgical specialties, and other specialties. By 2030, the study estimates a shortfall of between 7,300 and 43,100 primary care physicians. Non-primary care specialties are expected to experience a shortfall of between 33,500 and 61,800 physicians.

These findings are largely consistent with the 2015 and 2016 reports. In particular, the supply of surgical specialists is expected to remain level, while demand increases. The study also finds that the numbers of new primary care physicians and other medical specialists are not keeping pace with the health care demands of a growing and aging population.

“By 2030, the U.S. population of Americans aged 65 and older will grow by 55 percent, which makes the projected shortage especially troubling,” Kirch said. “As patients get older, they need two to three times as many services, mostly in specialty care, which is where the shortages are particularly severe.”

Expanding on last year’s findings, the new report also includes an analysis of the needs and health care utilization of underserved populations. These data show that if the barriers to utilization were removed for these patients, and all Americans accessed health care at the same levels as insured, non-Hispanic white populations, the United States would have needed up to 96,800 doctors in 2015. Nearly three-quarters of those physicians would be needed in metropolitan areas. This figure is in addition to the projected workforce shortage based on current practice patterns.

“Not only do these utilization equity data highlight the need for the nation to train more doctors, they also demonstrate the importance of a diverse health care workforce. Many of those who underutilize health care — despite their need — are from racial and ethnic minority backgrounds,” Kirch said. “A diverse and culturally competent workforce will enable us to provide the care all Americans need and deserve.”

To help alleviate the physician shortage, the AAMC supports a multipronged solution, including expanding medical school class size, innovating in care delivery and team-based care, making better use of technology, and increasing federal support for an additional 3,000 new residency positions per year over the next five years.

“We urge Congress to approve a modest increase in federal support for new doctors,” Kirch said. “Expanded federal support, along with all medical schools and teaching hospitals working to enhance education and improve care delivery, would be a measured approach to solving what could be a dangerous health care crisis.”

The Association of American Medical Colleges is a not-for-profit association dedicated to transforming health care through innovative medical education, cutting-edge patient care, and groundbreaking medical research. Its members comprise all 147 accredited U.S. and 17 accredited Canadian medical schools; nearly 400 major teaching hospitals and health systems, including 51 Department of Veterans Affairs medical centers; and more than 80 academic societies. Through these institutions and organizations, the AAMC serves the leaders of America’s medical schools and teaching hospitals and their nearly 160,000 faculty members, 83,000 medical students, and 115,000 resident physicians. Additional information about the AAMC and its member medical schools and teaching hospitals is available at www.aamc.org.
