"It has been widely recognized that methods and systems for insuring proper medication ingestion or administration by individuals are very important in defending against unnecessary sickness, deaths and other problems. Giving instructions and then letting patients fend for themselves has been shown not to work particularly well. This is because it is not only the improper ingestion of medicines that is the primary cause of medical danger. Rather, an overall lack of sufficient patient guidance is also part of the problem. Further, the inability to confirm a proper prescription regimen being provided to a user in the first place may cause a number of other problems with the use of such medication.
"These issues are even more problematic in a clinical trial setting where a lack of adherence to a particular assigned protocol may influence eventual approval of a particular drug therapy, potentially denying a valuable drug to the public and resulting in possible rejection of drugs that should be on the market that have been backed by pharmaceutical companies for hundreds of millions of dollars. Additionally, failure to adhere to prescribed protocols in clinical drug trials may result in poor data collection and evaluation, thus resulting in the above mentioned deaths from failure for trials to identify potentially life-threatening side effects. Poor adherence to prescribed protocols in clinical drug trials may refer to any deviation in a patient's behavior from that recommended by the trial designers, including, in addition to improper medication administration, improper timing of administration, such areas as dietary advice, advice on smoking, or even advice about attendance for further investigation or follow-up. Specifically in clinical trials, any such poor pharmaceutical compliance by the patient may result in inadequate results or outcomes.
"Corrupt or incomplete clinical trial data, inefficiency in following drug regimens and the inherent liability involved with clinical trials further complicate an already time consuming, complex, and expensive approval process which may take between 8 to 12 years and cost over
"Traditionally, participants attend introductions and follow ups for clinical trials in-person. Data collection is similarly limited to patient visits, rather than on a daily basis. Old methods such as patient questioning and pill counting have been proven to be inadequate measures of adherence and offer no information on dose timing and drug holidays (omission of medication for three or more sequential days).
"Compliance technologies can increase the statistical power of clinical trials. Through the use of such technology, clinical events can be precisely linked to medication use history. Captured data can be linked to other sources such as EDC, patient diaries and data collected by the physician. Technologies can create many possibilities for remote visits and data capture. While smart packaging technologies exist such as
"Jo Carol et al. stated that 'The most reliable method for research purposes, although not practical in a clinical setting, may be a combination approach that includes pill counts, patient self-report, and electronic monitoring.' (Carol J. et al, Patterns to Antiretroviral Medication, The Value of Electronic Monitoring, AIDS, 17 (12), pp 1, 763-767,
"Another problem is the issue of informed consent and the protection many clinical trials attempt to implement, often unsuccessfully, to protect themselves from potential lawsuits. A survey was conducted by CenterWatch (Getz, K. A. (2002). Informed consent process: A survey of subjects assesses strengths and weaknesses Applied Clinical Trials, 11(11), 30-36) to assess subjects' understanding of the consent documents further supports the concept that patients may not understand the forms they are signing. The survey reported that 14% of patients signed a consent document without reading the form. In the same survey, 30% of patients reported that they did not understand that their trial could carry more risk and discomfort than standard treatment. Nearly 40% of patients did not know that they could call an ethics board or IRB representative with questions about problems or concerns. The survey reported that 41% of patients did have study nurses review the consent form with them. The survey finally concluded that 70% of the participants may not have known what questions to ask at the outset of the informed consent process. And, this is with the current information provided and consent received from these participants. With approximately 77,967 trials in as many as 172 countries registered with ClinicalTrials.gov as of the date of this application, the logistical challenge of ensuring consistency is overwhelming.
"In patients with psychiatric illness, adherence may be even more difficult and technology solutions such as the one proposed in accordance with the present invention may offer accurate ways to authenticate adherence. According to
"The logistical challenge of medication adherence and auditing in clinical trials is certainly increasing, with more than 70,000 clinical trials under way throughout the world, growing at a rate of 8 to 10 percent a year, according to CenterWatch in
"Tufts CSDD Impact Report stated that within three years, major sponsors project that up to 65% of
"With greater amounts of clinical trials being conducted abroad, technology can aid standardization and provide greater communication where deficiencies in existing infrastructure such as physician and nurse training, may exist.
"A number of systems exist that provide instructions to a user regarding when to take a medication and records when the user indicates that a medication has been taken. U.S. Pat. No. 7,359,214 describes such a system. A device is provided that provides instruction to a patient regarding medications to take. Furthermore, the system may provide a method for determining that the prescription is appropriate given the patient's conditions, and other medications he or she may already be taking. The system may monitor the dispensing of medicine in accordance with a predetermined treatment protocol. While such a system provides many improvements for easing a burden on the patient, this system suffers in many ways and in particular in ways relevant to the administration of clinical trials.
"Most importantly, this system provides no mechanism for actually confirming that a patient is in fact ingesting or otherwise properly administering required medication as required in a clinical drug trial. While the system may be sufficient for one who is in full possession of their mental faculties, any individual who may have difficulty following directions, or one who is actively avoiding medication may still not be taking required medication after it is dispensed. Thus, participants may be forgetful, visually impaired, or otherwise do not believe in the benefit of taking such medication, and may thus not properly log medication administration. Furthermore, the system requires preloading of various medications into a dispenser, and thus likely requires regular visits by an administering manager to be sure appropriate medications are in fact properly loaded therein. It is surely possible that an inexperienced user may place incorrect medications into the device, or may somehow provide incorrect dosages into the device. Additionally, for potentially more complex regimens, there is no method provided for insuring that a user is able to follow such a protocol, and to thereafter confirm that the user has in fact taken all required medications in accordance with any provided instructions or the like, or has taken the medications according to one or more specifications or followed suggested procedures. Furthermore, this system is expensive and requires constant maintenance to confirm that the various mechanical parts are in working order.
"U.S. patent application Ser. No. 11/839,723, filed
"Additionally, existing systems fail to maintain an audit trail for post administration review by a medical official or other clinical trial administrator, and further cannot therefore confirm confirmation of proper medication administration.
"Therefore, it would be desirable to provide a method and apparatus that overcomes the drawbacks of the prior art."
As a supplement to the background information on this patent application, NewsRx correspondents also obtained the inventors' summary information for this patent application: "In accordance with the present invention, a system and method are provided that allow for complete control and verification of adherence to a prescribed medication protocol or machine or apparatus use in a clinical trial setting, whether in a health care provider's care, or when self administered in a homecare situation by a patient.
"The present invention is intended for the clinical trial market as a full audit and tracking tool for pharmaceutical compliance in subjects. The invention provides the only medication management system that may determine whether a user is actually following a protocol, provide additional assistance to a user, starting with instructions, video instructions, and the like, and moving up to contact from a medication administrator if it is determined that the user would need such assistance. Upon prescription of a medication to a user in a clinical trial, the trial designers may then select a desired protocol for the user to follow, and therefore, not only may a particular drug be tested, but also test the ease of adherence given a particular set of instructions.
"In recent years, the
"The novel combination of text, graphical, pictorial, and video allows the compliance problem within clinical trials to be tackled in a holistic manner. The system in accordance with the present invention offers a number of solutions. First, the system helps to ensure that the patient is giving informed consent. The system and method may provide step-by-step image and video instructions to the user or care provider on how to administer the medication, what the side effects of the medication are and the benefits that have been found. This avoids misunderstandings resulting from prescribing instructions and may allow an approach that may be utilized internationally, thus overcoming possible language barrier issues and the like.
"A specific medication regimen may be programmed into a medication calendar to alert the user when medication should be taken and provide clear video instruction for taking the medication. These reminders minimize forgetfulness by the subject in clinical trials and help the logistical challenges involved in complex medication regimen such as double blind studies, for example. Furthermore, the medication calendar and the compliance results are accessible to the clinical trial organizers.
"Once an alert is made and the patient has confirmed that they are ready to take the medication, the system and method of the invention record the type of medication and quantity through image recognition. The subject shows the medication to an imaging device which then authenticates the medication if in the correct dosage and offer administration instructions. Other types of recognition of the bottles may also be used, including
"As clinical trials begin, it will quickly become evident if a clinical trial is designed well and difficulties or non-compliance will be highlighted by the system and method of the invention. Often inconvenient or restrictive precautions prevent the medication regimen from being followed accurately and this type of feedback can be very useful. The system of the invention minimizes delinquent or inaccurate data submission by linking clinical events to medication use. The system also tracks the actions taken when a problem has been highlighted. This audit trail is then stored. Finally, if a patient is determined to be unable to follow a prescribed regimen, that patient may be identified and removed from the clinical trial population, or at least flagged, thus removing a confounding factor from the determination of whether a drug is safe and effective.
"The system and method preferably includes a means for receiving user medication information, including a medication profile and history, providing indications to a user regarding when to take a medication in accordance with a prescribed regimen in accordance with a clinical trial, and which medication to take, imaging medication either in pill or container form to confirm that a correct medication is being taken, confirming, in accordance with the user medication, that a new medication prescribed in accordance with a clinical trial will not conflict with another medication the user is already taking (including non-prescription medication that may be used by a patient), scan a group of medication containers or pills to inform a user which is the correct medication through the use of visual, verbal or other prompts, providing assistance information to aid a user in properly taking the medication, imaging, employing still photos, video sequences or other activity or gesture recognition techniques, the user to confirm that the medication is being actually and properly taken, providing any appropriate additional or special instructions so that the user is able to comply with the instructions of the clinical trial, using the imaging to note any possible adverse effects associated with taking of the medication, accumulating statistics about adherence to a prescribed protocol, assisting in reordering medication on an as-needed basis and notifying a clinical trial manager if the user is not properly following a prescribed protocol. If desired, a patient's face or other identifying features may be hidden so that the recorded sequences may be stored, displayed and otherwise used without allowing the identity of any particular patient to be released.
"From beginning to end, a user is provided with a system and method that aids the user in properly following a protocol as defined in a clinical trial setting, while informing an administrator of any deviations from the protocol, either innocent or purposeful, by a user so that an early intervention may be provided. The present invention is the only clinical trial medication adherence verification system that may determine whether a user is actually following a protocol, and provide additional assistance to a user, starting with instructions, video instructions, and the like, and moving up to intervention from a medication administrator through phone, email video conferencing or the like, if it is determined that the user may benefit from such assistance. Through such improved provision of care, potential clinical trial participants may be more likely to participate in such a clinical trial. The system may also identify individuals to be removed from a clinical trial population, and also possibly identify sets of instructions that may not be working to get people to follow the prescribed regimen.
"Still other objects and advantages of the invention will in part be obvious and will in part be apparent from the specification and drawings.
"The invention accordingly comprises the several steps and the relation of one or more of such steps with respect to each of the others, and the apparatus embodying features of construction, combinations of elements and arrangement of parts that are adapted to affect such steps, all as exemplified in the following detailed disclosure, and the scope of the invention will be indicated in the claims.
