Effect of mammographic screening from age 40 years on breast cancer mortality at 10 years' follow-up: a randomized controlled trial. At a mean follow-up of This is a reversal of the recommendation of mammographic screening every 1—2 years for women ages 40— Intrahepatic arterial versus intravenous fluorouracil and folinic acid for colorectal cancer liver metastases: a multicentre randomised trial.

Intrahepatic arterial infusion has been used as a method of delivering chemotherapy because it is thought that there would be a higher dose of chemotherapy to cancer cells, while lessoning the side-effects of chemotherapy Ansfield et al. Median survival in the IHA group was This is a reversal of the use of IHA for patients with colorectal cancer liver metastases. JAMA — Currently, there are two treatments commonly used for uveitis; the first approach is through systemic corticosteroids and corticosteroid-sparing immunosuppressive drugs Jabs et al.

The other, more recent approach was approved by the FDA in and involves surgically implanting fluocinolone acetonide implants Callanan et al. Change in mean visual acuity from baseline through 7 years was 1. This is a reversal of intravitreous fluocinolone acetonide implants for uveitis. None found Jakicic et al.

The study found that the standard intervention group experienced significantly more weight loss than the enhanced intervention group after 24 months 5. This is a reversal of wearable technology for long-term weight loss. This review did not include the RCT. Manson et al. Progesterone was thought to oppose the effects of estrogen and mitigate the excess risk of cancer, so women began to take them again.

This paper is an overview of the many health effects of HRT and found that there is a complex pattern of risks and benefits. The authors concluded that HRT is not an appropriate or recommended intervention for the prevention of chronic disease in postmenopausal women. Siversten et al.

Pharmacological interventions are common treatments prescribed by primary care physicians, yet sleep medication has shown to have a small effect size and clinical benefit, and long-term use of the drugs can cause dependency and increased tolerance Glass et al.

Zopiclone, a non-benzodiazepine sleeping pill, is also associated with next-day sleepiness and traffic collisions Allain et al. This study was the first RCT to compare the effects of nonbenzodiazepine sleep medications with nonpharmacological treatment. Zopiclone was no better than placebo in improving symptoms for patients with insomnia.

Consistent compressions in CPR is difficult while maintaining quality, and paramedics have been shown to provide shallower, slower compressions over time Ochoa et al. Manual chest compression devices were designed to provide ideal chest compressions. The two best cerebral performance categories at hospital discharge were recorded in 3. This is a reversal on the use of automated chest compression devices for resuscitation following out-of-hospital cardiac arrest.

More RCTs that measure and account for the CPR process in both arms are needed to clarify the potential benefit to be derived from this intervention.

To help prevent the spread of these organisms, policies recommending contact precautions e. This is a reversal of requiring that all health care workers in ICUs wear gloves and gowns for all patient contact and when entering a patient room. Binanay et al. PAC has been questioned for its safety and efficacy. They found that PAC increased adverse events This is a reversal of PAC for patients with congestive heart failure.

There were a number of RCTs investigating external hip protectors and hip fracture prevention showing with mixed results, Chan et al. This study found that prescribing a hip protector was not effective in preventing hip fractures in elderly persons aged 70 years and older compared to risk and bone health information. This is a reversal of external hip protectors for preventing fractures in elderly persons in institutional homes.

After excluding studies with high risk of bias, this Cochrane systematic review found that hip protectors did not have a significant effect on risk of hip fractures in institutional settings Santesso et al. Coleman et al. NEJM — Behavioral counseling is recommended for pregnant smokers, Lumley et al. In this trial, it was found that a nicotine patch was no more effective than placebo in helping pregnant women to quit smoking 9. This is a reversal on nicotine replacement therapy patches in pregnancy.

There is evidence, suggesting that when potentially-biased, non-placebo RCTs are excluded from analyses, NRT is no more effective than placebo. There is no evidence that NRT used for smoking cessation in pregnancy has either positive or negative impacts on birth outcomes Coleman et al. Nicolaides et al.

It is believed that this device reduces direct pressure on the cervix and prolongs pregnancy Arabin et al. This randomized trial compared spontaneous preterm births among women with pessaries with those who underwent expectant management and found that the pessary had no significant effect on the rate of preterm delivery This is a reversal of off-pump coronary-artery bypass. As the usage of glucocorticoid injections increased to treat various ailments, so did the cost.

This is a reversal of administering epidural glucocorticoid injections in patients who have lumbar central spinal stenosis and moderate-to-severe leg pain and disability. Traditionally, surgeons performed surgery on the arrested heart, on-pump CABG, which allowed for increased surgical precision Shroyer et al. However, surgeons grew concerned that the cross clamping of the aorta, necessary for the on-pump CABG procedure, may be harmful to patients and increase mortality and risk of stroke or other systemic embolic events in these patients.

The off-pump method, operating on a beating heart, was developed to decrease the perioperative risks Grover, The costs between the two treatments was similar as well. This is a reversal of off-pump coronary-artery bypass grafting. In contrast, we observed better long-term survival in the group of patients undergoing on-pump CABG with the use of cardiopulmonary bypass and cardioplegic arrest.

Based on the current evidence, on-pump CABG should continue to be the standard surgical treatment. However, off-pump CABG may be acceptable when there are contraindications for cannulation of the aorta and cardiopulmonary bypass.

Further randomised clinical trials should address the optimal treatment in such patients. Katz et al. Given the frequency and cost of arthroscopic partial meniscectomy and lack of concrete evidence on the clinical benefit of the procedure, the METEOR trial was designed to assess the efficacy of arthroscopic partial meniscectomy surgery as compared with a physical-therapy for increasing physical function of patients with a meniscal tear and moderate osteoarthritis Katz et al. METEOR found that there was not a significant decrease in the WOMAC score—a measure of physical function in which a higher score means worse physical function—between the patients undergoing surgery and those receiving initial physical therapy.

The authors conclude that the finding of the METEOR trial advocates for an initial nonoperative strategy for treatment. Given the current widespread use of arthroscopic meniscal surgeries, more research is urgently needed to support evidence-based practice in meniscal surgery in order to reduce the numbers of ineffective interventions and support potentially beneficial surgery.

This list represents practices from all disciplines of medical care. These practices add to a previously reported list of medical reversals published during years — Prasad et al.

Efforts to identify low-value practices are numerous. In the US Choosing Wisely initiative began by asking members of each medical specialty to provide a list of the top five diagnostic tests or treatments that are expensive and have evidence showing a lack of benefit Schpero, : similar initiatives have been implemented in other countries de Vries et al.

Some have performed systematic searches of the scientific databases using key words de Vries et al. Others have used a multiplatform attempt, consisting of searching the peer-reviewed literature, insurance and health organization databases, and opportunistic samplings of knowledgeable experts in the field Elshaug et al. Each of these ways to identify medical reversals or low-value practices has advantages and disadvantages, but identifying these practices can be challenging because of their heterogeneity, the lack of established methods to identify these practices, the difficulty in applying them to the correct population or subpopulation, and the obstacle of prioritizing which practices are more or less low-value Elshaug et al.

Prior work by Schwartz and colleagues approximated the financial costs of 26 low-value services that are more commonly used in the older adult population Schwartz et al. These results are especially notable considering the authors only used the 26 most commonly used low-value services. In contrast, the ubiquity of medical reversals has been previously reported upon in the NEJM, where practices were identified as medical reversals over a decade Prasad et al.

Here, we hope to add to the prior efforts of others in providing a larger and more comprehensive list practices in total for clinicians and researchers to guide practice as they care for patients more effectively and more economically.

Here, we hope to add to the prior efforts of others in providing a larger and more comprehensive list practices in total for clinicians and researchers to guide practice as they care for patients more effectively and more economically. We found reversals in a variety of medical sub-fields and types of devices, procedures, or practices. These reversals had been practiced and tested in high-income as well as low- to middle-income countries, although the highest percentage of reversals was in high-income countries, likely because most randomized trials are performed in this setting.

For example, bevacizumab Avastin was approved in by the Food and Drug Administration FDA in the US for metastatic breast cancer under the accelerated approval program, but was later shown to not improve overall survival Vitry et al. Reversals were not just limited to practices performed by physician or health care providers only. Wearable technology has become especially popular among people who are interested in tracking their physical activity in an effort to lose weight.

A study on the use of wearable technology, however, found that weight loss was significantly less among the group that had access to wearable technology, compared to the group that did not Jakicic et al.

With increasing availability of healthcare interventions that are readily accessible to everyone without a prescription, there needs to be greater discussion on whether these work between patients and physicians, as well as discussion on the regulation of these interventions.

Finally, reversals highlight the importance of independent, governmental and non-conflicted funding of clinical research.

Extraordinary care, just for kids!

The majority of reversal studies we found were funded by such sources Strengths and limitations There are several strengths and limitations to this paper. First, we looked at just three journals each of which has a high impact factor.

Second, documented evidence of the use of a newer practice was sometimes easier to find because it had come about during a time when there was more internet use. Conversely, documented evidence of an older practice was sometimes easier to find because there had been more historical commentary about its use.Edition: Essentials of. Because of this, newer or more recent practices may be more or less likely to be categorized as established than older or less recent practices.
