(Press-News.org) In an examination of the effect of financial incentives on hypertension care at 12 outpatient clinics, physician-level (individual) financial incentives, but not practice-level or combined incentives, resulted in greater blood pressure control or appropriate response to uncontrolled blood pressure, according to a study in the September 11 issue of JAMA. None of the incentives resulted in greater use of guideline-recommended medications compared with controls.
"As part of the Affordable Care Act, the U.S. government has introduced pay for performance to all hospitals paid by Medicare nationwide. The New York City Health and Hospitals Corporation recently announced a performance pay plan for physicians. These and other value-based purchasing systems are intended to align incentives to promote high-quality health care. Evaluations of the effectiveness of pay-for-performance programs directed at hospitals have shown contradictory results," according to background information in the article.
Laura A. Petersen, M.D., M.P.H., of the Veterans Affairs Medical Center and Baylor College of Medicine, Houston, and colleagues conducted a randomized controlled trial to test the effect of explicit financial incentives to individual physicians and practice teams for the delivery of guideline-recommended care for hypertension in the primary care setting. The trial at 12 Veterans Affairs outpatient clinics with 5 performance periods enrolled 83 primary care physicians and 42 nonphysician personnel (e.g., nurses, pharmacists). The interventions were physician-level (individual) incentives, practice-level incentives, both, or none. Intervention participants received up to 5 payments every 4 months; all participants could access feedback reports. The primary measured outcomes were the number of patients (among a random sample) achieving guideline-recommended blood pressure thresholds or receiving an appropriate response to uncontrolled blood pressure, the number of patients prescribed guideline-recommended medications, and the number who developed hypotension (abnormally low blood pressure).
Among physicians who participated in all 5 performance periods, the average total payment for physicians over the course of the study was $4,270 in the combined physician and practice-level group, $2,672 in the individual physician-level group, and $1,648 in the practice-level group. Change in blood pressure control or appropriate response to uncontrolled blood pressure compared with the control group was greater only in the individual incentives group. The difference in change in proportion of patients achieving blood pressure control or receiving an appropriate response between the individual incentive and no incentive group was 8.36 percent.
Although the use of guideline-recommended medication increased over the course of the study in the intervention groups, there was no change compared with controls.
The researchers did find that far more intervention than control group participants viewed their feedback reports on the website (67 percent vs. 25 percent), suggesting that participants were aware of the relationship between performance and rewards.
"Although concerns about overtreatment have been cited in criticisms of pay-for-performance programs, we did not find a higher incidence of hypotension in the panels of physicians randomized to the incentive groups," they write.
Even small reductions in blood pressure translate into significant reductions in morbidity and mortality, and in system-wide costs, the authors write. "This trial addresses the needs of policy makers and payers for information about a clinically relevant payment intervention in routine practice. Payment-system interventions are attractive because of their potential scale and reach. However, payment-system interventions are only one piece of the solution to improve management of chronic diseases such as hypertension. More resource-intensive, tailored, patient-level self-management strategies may be needed to truly affect patient outcomes."

Incentive program for small practices with EHRs results in improvement in CV outcomes
2013-09-11
A pay-for-performance program in electronic-health-records-(EHR)-enabled small practices led to modest improvements in cardiovascular care processes and outcomes, according to a study in the September 11 issue of JAMA.
"Most evaluations of pay-for-performance (P4P) incentives have focused on large-group practices," according to background information in the article. Small practices, where the majority of patients still receive care nationally, historically have provided lower-quality care—especially solo practices—and may have greater obstacles to improving care because ...
Use of EHRs for patients with diabetes linked with reduction in ED visits, hospitalizations
2013-09-11
Among patients with diabetes, use of an outpatient electronic health record (EHR) in an integrated healthcare delivery system was associated with modest reductions in emergency department visits and hospitalizations, but was not associated with a change in office visit rates, according to a study in the September 11 issue of JAMA.
The Health Information Technology for Economic and Clinical Health (HITECH) Act authorizes up to $27 billion during 10 years to promote meaningful use of EHRs, with penalties for lack of EHR use beginning in 2015. With these substantial incentives, ...
Combination therapy for severe alcoholic hepatitis does not result in improved survival
2013-09-11
Four weeks of treatment with a combination of the drug pentoxifylline and the corticosteroid prednisolone did not improve 6-month survival compared with prednisolone alone in 270 patients with severe alcoholic hepatitis, according to a study in the September 11 issue of JAMA.
Treatment of severe forms of alcoholic hepatitis is extremely challenging because of the poor outcome. European and U.S. guidelines recommend the use of prednisolone or pentoxifylline in patients with severe alcoholic hepatitis. Nevertheless, a substantial proportion of patients die after 6 months ...
Use of EHRs associated with higher rate of detection of growth disorders in children
2013-09-11
"Monitoring of linear growth is a well-established part of pediatric health care in the developed world. Although monitoring aims to support early diagnosis and timely treatment of disorders affecting growth, such disorders are often diagnosed late," write Ulla Sankilampi, M.D., Ph.D., of Kuopio University Hospital, Kuopio, Finland, and colleagues.
As reported in a Research Letter, the authors compared the effectiveness of a novel computerized and automated growth monitoring (AGM) strategy integrated into an electronic health record (EHR) system in the primary care setting ...
Improved adherence to preventive antiretroviral therapy may reduce transmission of HIV
2013-09-11
A recently completed substudy of a larger clinical trial found that pre-exposure prophylaxis -- a new strategy to prevent HIV infection by prescribing a daily antiretroviral drug to at-risk individuals -- can be a powerful tool when participants take their medications. The trial of this strategy, also called PrEP, enrolled uninfected individuals in East Africa with an HIV-positive sexual partner and found that a combination of objective monitoring of how often participants took their daily medications and intensive counseling of those with lower rates of adherence prevented ...
Pay for performance encouraged physicians to follow blood pressure guidelines
2013-09-11
HOUSTON (Sept. 11, 2013) – When health care pundits began to suggest that pay-for-performance would solve some of health care's woes, Dr. Laura Petersen, professor of medicine at Baylor College of Medicine and director of the Houston VA Health Services Research and Development Center of Excellence, had questions.
How do we know that it will solve those problems? she asked. How do we know whether or not it will create new problems? And how will we structure these payments? As a recognized expert in the area of health care services and quality, she set out to find the ...
Bad news for prey: New research shows that predators can learn to read camouflage
2013-09-11
Camouflaged creatures can perform remarkable disappearing acts but new research shows that predators can learn to read camouflage. The study, which used human subjects as predators searching for hidden moths in computer games, found that the subjects could learn to find some types of camouflaged prey faster than others.
The research was carried out by the University of Exeter and the University of Cambridge and is published in the journal PLOS ONE. Moths with high contrast markings - that break up the shape of the body, like that of a zebra or giraffe - were best at ...
New cell component important to tea and wine-making
2013-09-11
Scientists have discovered where plants build tannins, complex chemicals used by plants for defence and protection. The source is the tannosome, a newly discovered organelle that is found in most land plants.
All living things are made from cells; whether they are single-celled organisms like amoeba, or enormous entities like Giant Redwoods (in which millions of cells make up the body of the organism). Although cells may become specialised for particular roles in an organism, they each undertake many different tasks. Internally each cell is furnished with a range of smaller ...
Researchers map carbon footprints of UK towns and cities
2013-09-11
The London borough of Newham is famed for producing talents such as Idris Elba, Plan B and Mo Farrah, whilst also playing host to the Olympic Stadium and West Ham United Football Club.
Now an international group of researchers have found that its residents have the smallest carbon footprint in the UK.
In a study of 434 municipalities across England, Wales, Scotland and Northern Ireland, they showed that according to data taken from 2004, the lifestyle of each person in Newham caused an average of 10.21 tonnes of carbon dioxide (CO2) to be emitted into the atmosphere ...
Childbirth risks not the same for all obese women
2013-09-11
Obesity raises the chances of complications and medical interventions in childbirth. But a new study by Oxford University shows the risks are not the same for all obese women.
For otherwise healthy women, the increase in risk with obesity may not be as great as previously suspected.
'The increased risk was fairly modest for obese women who did not have conditions such as high blood pressure, diabetes or a previous caesarean section, and the risks were quite low if the woman had given birth previously,' says lead researcher Dr Jennifer Hollowell of the National Perinatal ...
