Published Studies Related to Plan B One-Step (Levonorgestrel)

Short-Term Treatment of Bothersome Bleeding for Etonogestrel Implant Users Using a 14-Day Oral Contraceptive Pill Regimen: A Randomized Controlled Trial. [2015]
during a 14-day course... CONCLUSION: Bothersome bleeding in etonogestrel contraceptive implant users will

An overview of four studies of a continuous oral contraceptive (levonorgestrel 90 mcg/ethinyl estradiol 20 mcg) on premenstrual dysphoric disorder and premenstrual syndrome. [2012]
and premenstrual syndrome (PMS)... CONCLUSIONS: These data, although not consistent, indicate that continuous LNG/EE

Ethinyl estradiol and levonorgestrel pharmacokinetics with a low-dose transdermal contraceptive delivery system, AG200-15: a randomized controlled trial. [2011.11.29]
BACKGROUND: This study evaluated the ethinyl estradiol (EE) and levonorgestrel (LNG) pharmacokinetic profiles of AG200-15, a transdermal contraceptive delivery system, compared with a combination oral contraceptive (COC) containing EE 35 mcg and norgestimate 250 mcg... CONCLUSIONS: EE and LNG daily exposure during AG200-15 treatment was within the range reported for a low-dose COC. The daily EE dose with AG 200-15 was equivalent to a 30-mcg COC and was safe and well tolerated. Copyright (c) 2011 Elsevier Inc. All rights reserved.

Naproxen or estradiol for bleeding and spotting with the levonorgestrel intrauterine system: a randomized controlled trial. [2011.09.24]
OBJECTIVE: The purpose of this study was to evaluate whether oral naproxen or transdermal estradiol decreases bleeding and spotting in women who are initiating the levonorgestrel-releasing intrauterine system... CONCLUSION: The administration of naproxen resulted in a reduction in bleeding and spotting days compared with placebo. Copyright A(c) 2011 Mosby, Inc. All rights reserved.

Immediate versus delayed insertion of the levonorgestrel-releasing intrauterine device following dilation and evacuation: a randomized controlled trial. [2011.09.13]
BACKGROUND: The study was conducted to compare 6-month usage of the levonorgestrel-releasing intrauterine device (LNG-IUD) when placed immediately or 3 to 6 weeks after dilation and evacuation (D&E) procedure... CONCLUSION: Significantly more participants had the LNG-IUD placed in the immediate insertion group compared with the delayed insertion group. Given the low risk of complications, immediate post-D&E insertion of the LNG-IUD should be offered, especially for populations that may have difficulty returning for follow-up.

Clinical Trials Related to Plan B One-Step (Levonorgestrel)

Written Asthma Actions Plans Versus No Written Instructions In Specialty Care [Completed]
The overall goal of this randomized, controlled study is to compare a model written treatment plan with the usual care that is provided by a group of adult and pediatric pulmonologists and allergists in their practice settings. The written treatment plan is a form that allows a treatment regimen that is consistent with National Heart, Lung, and Blood Institute (NHLBI) guidelines to be conveyed to patients. Barriers to the use of written plans will be identified to better understand why some patients and physicians use written treatment plans more frequently and effectively than others. An additional goal is to assess how patients from different racial/ethnic backgrounds utilize treatments plans. Because asthma disproportionately affects African American and Latino patients, another goal of this study is to better understand if there are fundamental differences in the way patients from racial/ethnic minority groups self-manage asthma in comparison to their white counterparts. The study will also try to determine if differences exist in the way physicians care for minority patients. If there are differences, it is important to determine if the disparities can be overcome with the use of a written treatment plan form.

Wellness Action Plan Trial Addressing Childhood Obesity [Completed]
The objective of this study was to determine the effectiveness of a novel Wellness Action Plan aimed at 1) improving parent recall of diet and activity plans 2) increasing follow-through with plans and 3) aiding parents in identifying their child's weight category.

Patient and Provider Initiated Survivorship Care Planning [Recruiting]
Objective: to describe and compare the implementation of two cancer survivorship care tools: (1) 'My Care Plan': a patient-initiated tool and (2) 'Survivorship Care Plan Builder': a provider-initiated tool. The results of this study will be used to (1) provide an initial assessment of the two survivorship care planning tools and (2) inform the design and conduct of a larger study.

Comparing Asthma Action Plans for Pediatric Asthma [Terminated]
The purpose of this study is to evaluate and compare the relative effectiveness of two asthma action plans (pictorial versus written) in terms of asthma action plan knowledge, medication use, and family satisfaction with asthma education.

Study of Survivorship Care Plans and Outcomes in Underserved Breast Cancer Survivors [Active, not recruiting]
Improvements in early detection and successful treatment of breast cancer have lead to a steady rise in the number of breast cancer (BC) survivors. With so many individuals living for extended periods after diagnosis, the Institute of Medicine (IOM) recommends the implementation of treatment summaries and survivorship care plans (TSSPs) as a mechanism to improve ongoing clinical and coordination of care, and to address the immediate post-treatment and long-term effects of cancer treatment, including the ongoing psychosocial burden of a cancer diagnosis. The need for TSSPs has also been strongly advocated by the American Society of Clinical Oncology's Quality Oncology Practice Initiative and TSSPs have been included in the recently introduced Comprehensive Cancer Improvement Act (H. R. 1844). This will be one of the first randomized controlled trials to test the efficacy of TSSPs. The investigators will recruit 500 low income, medically underserved women from two county public hospitals, LAC+USC Medical Center and Harbor-UCLA Medical Center, 10-24 months after breast cancer diagnosis for participation in a randomized controlled trial (RCT) designed to test the efficacy of TSSPs. The investigators will randomize these women into one of two groups: 1) a control condition of usual medical care and 2) an experimental condition of the control condition + a tailored TSSP + 1 face-to-face nurse counseling session, with all cancer specialists and primary care physicians of record also receiving the TSSP and a cover letter suggesting how they can be clinically utilized. The investigators specific aims are to assess and compare between experimental and control groups the following primary outcomes at one year post-intervention: 1) discussion and implementation of recommended breast cancer survivorship care, including surveillance and the evaluation and management of BC treatment-related symptoms, 2) patient satisfaction with survivorship communication and care, 3) pertinent aspects of health-related quality of life, and further, to then 4) assess the cost-consequences of the experimental intervention. This study will provide a unique opportunity to assess the efficacy of TSSPs in a low-income, underserved population of BC survivors known to be at high risk for poorer long-term outcomes, including in mental health, quality of life, recurrence and mortality, and will therefore allow us to demonstrate the greatest possible benefit of such an intervention.
