Brief Title ICMJE | Oral Psoriasis Treatment Adherence and Intervention Study | ||||
Official Title ICMJE | Oral Psoriasis Treatment Adherence and Intervention Study | ||||
Brief Summary | Response to psoriasis treatment is variable in large part because of poor adherence treatments. Studies using electronic monitors have assessed adherence to topical and injectable psoriasis treatments and to biologics, yielding critically important insights. Adherence to oral psoriasis treatments is not as well characterized but is also critical, as the therapeutic windows for these treatments are narrower than for other psoriasis treatment options. The proposed study will assess patients' adherence to oral psoriasis treatment (primarily methotrexate) and will also collect pilot data on an intervention to improve adherence. The primary hypothesis of the investigators study is that adherence to oral psoriasis treatment is poor and that a reporting intervention may improve adherence to oral psoriasis treatment. In the investigator-blinded, 6-month prospective study, patients will be randomized to standard-of-care treatment or standard-of-care supplemented with the weekly online reporting intervention. Adherence will be assessed using electronic monitors. This randomized trial will permit the investigators to determine adherence to oral psoriasis treatment, assess the relationship between adherence and psoriasis outcomes, identify factors that are associated with adherence to oral psoriasis treatment (including physician trust, confidence in the treatment plan, and depression), and obtain preliminary data on the impact of an Internet-reporting measure on patients' adherence to oral psoriasis treatment . | ||||
Detailed Description | Psoriasis is a common, chronic inflammatory disease that has a major impact on patients' quality of life. Patients' response to treatment is variable. Poor adherence to topical, oral and biologic psoriasis treatments is common and may account for poor responses.1, 2 Many psoriasis patients do not even fill their prescriptions.3 Electronic monitoring of adherence provides the most detailed and accurate way to assess adherence. While studies using electronic monitors have assessed adherence to topical psoriasis treatments and to biologics, adherence to oral psoriasis treatments is not as well characterized. Understanding adherence to oral psoriasis treatments is critical, as the therapeutic windows for these treatments are narrower than for other psoriasis treatment options, making adherence to recommended dosing all the more critical. Developing methods to improve psoriasis patients' adherence has the potential to provide an immediate, practical means to improve patients' treatment outcomes. Return visits improve patients' use of medication & treatment outcomes but are not practical and add additional costs to the patient and medical system. Having patients report on their treatment experience without an office visit offers promise for improving adherence but has not been tested in a psoriasis population. The primary hypothesis of the investigators study is that adherence to oral psoriasis treatment is poor and that a reporting intervention may improve adherence to oral psoriasis treatment. The Specific Aims of this study are:
The investigators propose an investigator-blinded, 6-month prospective study of 40 patients aged 12 and older who have been prescribed oral psoriasis treatment. Adherence will be assessed using Medication Event Monitoring System (MEMS®) caps, electronic monitors affixed to the medication containers. Investigators and subjects will be blinded to the adherence data until the final (Month 6) treatment visit. This study is of high significance, providing critically important information on how patients use oral psoriasis treatments, as well as a foundation to develop and implement intervention trials to improve adherence and outcomes in patients treated with oral psoriasis treatments. Innovations in this study include seeking to change the paradigm of the investigators understanding of the role of adherence in oral psoriasis treatment, including effects on treatment failures and side effects, developing a new understanding of the roles of physician and medication trust in adherence, and potentially changing the timing and methods of clinical assessments in psoriasis (and other) patients in light of the effects of the timing and methods of clinical assessments on treatment adherence and outcomes. The use of objective electronic adherence monitors and well-validated assessment tools adds strength to the approach of this study; another strength of the approach is careful attention to research ethics of adherence monitoring. The environment of this study is particularly strong, with facilities for and extensive experience in all aspects of adherence monitoring research. The overall goal of this study is to better understand and improve adherence behaviors in patients with psoriasis, a common, chronic, relapsing, inflammatory disease. Psoriasis reduces patients' quality of life, yet patients with psoriasis, as with other chronic diseases, frequently misuse medicine, impairing effectiveness of prescribed therapies (when underused) and increasing the risks of treatment (when overused or mistimed).8 Poor adherence to treatment can be misconstrued as poor response, which can lead to unnecessary treatment escalation resulting in exposing patients to more toxic or costly medications.9 In many cases, non-adherence, rather than non-response, is the underlying precursor of treatment failure.10, 11 Adherence issues with oral psoriasis treatment are largely unexplored and are of critical importance. Oral methotrexate is widely used (encouraged by payors), yet it is risky, with a more narrow therapeutic window than biologics. Other oral agents approved for psoriasis include cyclosporine (with a risk of renal disease) and apremilast (which is associated with gastrointestinal tolerability issues). While large database studies find that oral psoriasis treatment is underused, the variation in use of oral psoriasis treatments among patients is critically important and has not been defined. Traditional methods for measuring medical adherence tend to be unreliable. Assessment methods such as patient interviews, questionnaires, surveys, and diaries deliver inconsistent data that depend upon the patient's willingness to accurately record medication use and ability to remember what they did. Electronic monitoring devices offer an effective means for objective adherence monitoring. Medication Event Monitoring System caps (MEMS®, AARDEX Corp., Fremont, CA) include microprocessors in the bottle cap of a standard medication bottle that record each time and date the bottle is opened and the interval since the last bottle opening.12 The availability of accurate electronic adherence measurement provides a foundation to study novel ways to improve adherence. In several studies of psoriasis and other inflammatory skin diseases, a clear pattern of improved adherence around the time of office visits is evident. The tendency for patients to be more adherent around the time of office visits may be a form of a more general tendency to be adherent when interacting with the healthcare system to assess their treatment outcomes, a form of "white coat compliance" or Hawthorne effect. A pilot study of adolescents with acne vulgaris tested whether adherence to topical benzoyl peroxide could be improved by weekly online-reporting of their treatment experience. | ||||
