About
The purpose of this study is to evaluate whether a novel prescription method (N-of-1 intervention)can be successfully integrated into primary care practices and to examine the effects of this prescription method on selected patient health outcomes (e.g.., medication compliance, medication costs, symptom management, satisfaction of physician/patient visit, etc.) in patients with a uncontrolled or new diagnosis of Osteoarthritis or Chronic Heartburn (GERD).
Full description
The current prescription writing behavior of physicians is largely an informed decision based upon education and experience. The physician typically assesses the signs and symptoms of a patient presentation, laboratory and other clinical tests, and other factors that may be known to the physician (e.g. an inability to swallow capsules, or a requirement to be in direct sunlight for an extended period), and chooses a drug to prescribe with no evidence of patient response to the agent prescribed. The prescribing physician may or may not decide to validate this decision by additional testing in the form of follow-up visits or other procedures that are designed to assess the effectiveness of the prescription after some arbitrary period of time, but not comparatively with other available agents.
Other influences may impact the decision including aggressive promotions by pharmaceutical companies in support of their latest medication and direct to consumer retail advertising. Studies conducted by the University of Washington Medical School have shown that when patients merely enquire about a drug for which they've seen advertising, that drug is then more frequently prescribed (Hollon 2005). At its best, prescription writing is an educated guess with a scheduled follow-up to verify the results of the decision. At its worst, it may result in all risk with no benefit to the patient if the patient is a non-responder, or if the patient accepts an adverse outcome without informing the physician.
The Opt-e-scrip method for determining prescriptions is virtually the same method that is used to assess new drugs for regulatory approval (i.e.,controlled experiments to reduce systematic error, reduce random variation, increase precision of assessment). However, instead of applying the techniques of scientific investigation to populations, these methods are applied to the individual patient. Opt-e-scrip's proprietary methods are used to assess alternative choices within a therapeutic class for effectiveness and safety before prescribing a specific agent for an individual patient. In this case, however, because the drugs are already marketed and cost information is available, when two or more agents are equally safe and effective, a decision can be made reliably on cost as a relevant factor (2006).
Initial studies indicate that the Opt-e-scrip methodology can distinguish between similar medications based on efficacy and/or side effects at the individual patient level in patients with osteoarthritis, gastroesophageal reflux disease (GERD), and allergic rhinitis (Reitberg, Del Rio et al. 2002; Reitberg, Weiss et al. 2005). It remains to be seen how well this method can be integrated into clinical care and how clinicians and patients respond to the method as part of routine care. This project will assess the integration of Opt-e-scrip method into 20 primary care practices that will each use the method to assist with medication selection in 30 to 40 patients with a new diagnosis or uncontrolled osteoarthritis and GERD.
