Behavior during these times can often lead to damage to the surroundings and injury to the patient or to others pain management for dogs with hip dysplasia discount maxalt 10 mg visa. In many of these cases acute neck pain treatment guidelines purchase 10mg maxalt with mastercard, the nature of these conditions may be established by careful clinical evaluation allied pain treatment center youngstown oh buy 10mg maxalt with mastercard. In cases where seizure disorders have been ruled out and in cases that present a history of repeated violent or injurious episodes during sleep southern california pain treatment center generic maxalt 10mg amex, polysomnography may be useful in providing a diagnostic classification or prognosis pain treatment for trigeminal neuralgia order maxalt with a mastercard. Evidence at the present time is not convincing that polysomnography in a sleep disorder clinic for chronic insomnia provides definitive diagnostic data or that such information is useful in patient treatment or is associated with improved clinical outcome pain treatment hemorrhoids cheap 10mg maxalt with amex. Sleep disorder clinics may at times render therapeutic as well as diagnostic services. Therapeutic services may be covered in a hospital outpatient setting or in a freestanding facility provided they meet the pertinent requirements for the particular type of services and are reasonable and necessary for the patient, and are performed under the direct supervision of a physician. Under general supervision, the training of the nonphysician personnel who actually performs the diagnostic procedure and the maintenance of the necessary equipment and supplies are the continuing responsibility of the physician. Direct Supervision in the office setting means the physician must be present in the office suite and immediately available to furnish assistance and direction throughout the performance of the procedure. It does not mean that the physician must be present in the room when the procedure is performed. Personal Supervision means a physician must be in attendance in the room during the performance of the procedure. Diagnostic tests may be furnished under situations that meet the incident to requirements but this is not required. Clinical laboratory services involve the biological, microbiological, serological, chemical, immunohematological, hematological, biophysical, cytological, pathological, or other examination of materials derived from the human body for the diagnosis, prevention, or treatment of a disease or assessment of a medical condition. Section 1862(a)(1)(A) of the Act provides that Medicare payment may not be made for services that are not reasonable and necessary. See the Medicare Claims Processing Manual Chapter 16 for related claims processing instructions. Experience has shown that the failure to inform laboratories of Medicare regulations and claims processing procedures may have an adverse effect on prosecution of laboratories suspected of fraudulent activities with respect to tests performed by, or billed on behalf of, independent laboratories. United States Attorneys often have to prosecute under a handicap or may simply refuse to prosecute cases where there is no evidence that a laboratory has been specifically informed of Medicare regulations and claims processing procedures. G Where it is medically necessary for an independent laboratory to visit a patient to obtain a specimen, the service would be covered in the following circumstances: 1. However, where the specimen is a type which would require only the services of a messenger and would not require the skills of a laboratory technician. When facility personnel actually obtained and prepared the specimens for the independent laboratory to pick them up, the laboratory provides this pickup service as a service to the facility in the same manner as it does for physicians. Payment for psychological and neuropsychological tests is authorized under section 1842(b)(2)(A) of the Social Security Act. Under the diagnostic tests provision, all diagnostic tests are assigned a certain level of supervision. Generally, regulations governing the diagnostic tests provision require that only physicians can provide the assigned level of supervision for diagnostic tests. However, there is a regulatory exception to the supervision requirement for diagnostic psychological and neuropsychological tests in terms of who can provide the supervision. See qualifications under chapter 15, section 200 of the Benefit Policy Manual, Pub. See qualifications under chapter 15, section 210 of the Benefit Policy Manual, Pub. See qualifications under chapter 15, section 190 of the Benefit Policy Manual, Pub. Possible reference sources are the national directory of membership of the American Psychological Association, which provides data about the educational background of individuals and indicates which members are board-certified, the records and directories of the State or territorial psychological association, and the National Register of Health Service Providers. Payment for Diagnostic Psychological and Neuropsychological Tests Expenses for diagnostic psychological and neuropsychological tests are not subject to the outpatient mental health treatment limitation, that is, the payment limitation on treatment services for mental, psychoneurotic and personality disorders as authorized under Section 1833(c) of the Act. Under the physician fee schedule, there is no payment for services performed by students or trainees. Audiological diagnostic testing refers to tests of the audiological and vestibular systems. If a beneficiary undergoes diagnostic testing performed by an audiologist without a physician order, the tests are not covered even if the audiologist discovers a pathologic condition. When a qualified physician orders a qualified technician (see definition in subsection D of this section) to furnish an appropriate audiology service, that order must specify which test is to be furnished by the technician under the direct supervision of a physician. Diagnostic services furnished by a qualified audiologist meeting the requirements in section 80. Reevaluation is appropriate at a schedule dictated by the ordering physician when the information provided by the diagnostic test is required, for example, to determine changes in hearing, to evaluate the appropriate medical or surgical treatment or to evaluate the results of treatment. The qualifications for technicians vary locally and may also depend on the type of test, the patient, and the level of participation of the physician who is directly supervising the test. For example, documentation should indicate that the test was ordered, that the reason for the test results in coverage, and that the test was furnished to the patient by a qualified individual. There is no provision in the law for Medicare to pay audiologists for therapeutic services. For example, vestibular treatment, auditory rehabilitation treatment, auditory processing treatment, and canalith repositioning, while they are generally within the scope of practice of audiologists, are not those hearing and balance assessment services that are defined as audiology services in 1861(ll)(3) of the Social Security Act and, therefore, shall not be billed by audiologists to Medicare. Services for the purpose of hearing aid evaluation and fitting are not covered regardless of how they are billed. When a physician or supplier furnishes a service that is covered by Medicare, then it is subject to the mandatory claim submission provisions of section 1848(g)(4) of the Social Security Act. Therefore, if an audiologist charges or attempts to charge a beneficiary any remuneration for a service that is covered by Medicare, then the audiologist must submit a claim to Medicare. When furnishing services that are not on the Medicare list of audiology services, the audiologist may or may not be working within the scope of practice of an audiologist according to State law. The audiologist furnishing the service must have the qualifications that are ordinarily required of any person providing that service. Medicare is not authorized to pay for these services when performed by audiological aides, assistants, technicians, or others who do not meet the qualifications below. B the health and safety standards apply to all suppliers of portable x-ray services, except physicians who provide immediate personal supervision during the administration of diagnostic x-ray services. Payment is made only for services of approved suppliers who have been found to meet the standards. This rule implemented several changes effective January 1, 2007, which are reflected below. A physician or qualified nonphysician practitioner treating the beneficiary for purposes of this provision is one who furnishes a consultation or treats a beneficiary for a specific medical problem, and who uses the results in the management of the patient. A woman who has been determined by the physician or qualified nonphysician practitioner treating her to be estrogen-deficient and at clinical risk for osteoporosis, based on her medical history and other findings. An individual with vertebral abnormalities as demonstrated by an x-ray to be indicative of osteoporosis, osteopenia, or vertebral fracture. An individual receiving (or expecting to receive) glucocorticoid (steroid) therapy equivalent to an average of 5. A radiologist performing a therapeutic interventional procedure is considered a treating physician. A radiologist performing a diagnostic interventional or diagnostic procedure is not considered a treating physician.

In trephine biopsy, histology is well delineated and myelofibrosis can be confirmed. A small guard with a head and flattened stalk which fits in with the barrel of the Indications base of the needle. Unexplained hepatomegaly/hepatosplenomegaly it can allow free flow of blood and saline and not the 2. Shock is usually caused by rapid loss of blood from in full expiration in the mid axillary line. Bacterial peritonitis (injury to hepatic flexure of with a saline filled syringe is passed through the colon). Before entering into the liver, the unwanted tissue that would have entered the needle, should be syringed off by pushing saline. With suction Kidney Biopsy on, the needle must be pushed into the liver and Patients with renal glomerular disease may present with withdrawn immediately like a bonnet drill. Their prognosis and treatment the same can be pushed into a bottle with formalin depend on the renal pathology, and histological by injecting saline in the syringe. A cord like liver examination of the kidney is often the only way to make tissue can be obtained if the liver is not cirrhotic. It is most valuable in assessing and, this is a larger needle and has a stylet, barrel and in particular, indicating the prognosis of patients with biforked biopsy blade which is longer than the needle diffuse glomerular disease. The advantage of this needle is that it has a Contraindications success rate of approximately 95%. The trocar is longer than the A single kidney or major abnormality of the contracannula. The needle is advanced till it begins to swing mL and the prothrombin time must be normal. The needle is then slightly withdrawn Biopsy should not be done on shrunken kidneys until it stops swinging. The patient is then instructed to because they are difficult to locate, the histological hold his breath in expiration and the needle is thrust for findings are often non-specific, and the results are about 2 to 3 cm into the liver. The inner trocar is unlikely to provide information of any therapeutic advanced holding the outer cannula with the cutting relevance. The outer cutting sheath is then advanced over the inner trocar to cut the liver in the biopsy notch. Procedure the needle (trocar and cannula) is then quickly Before starting the procedure, grouping and crosswithdrawn after completing the procedure. Aftercare the procedure should be explained to the patient, the patient is instructed in to lie on the right side for and patient should practice holding his breath in four hours and to remain in bed for 24 hours. Biopsy is unsafe if patient cannot cooperPulse rate and blood pressure are recorded hourly.

The the procedure less unpleasant for the patient; general obturator and the cannula are withdrawn after anaesthesia is required only for infants and young completing this procedure. A successful biopsy produces a strip of kidney up to the patient is placed in the prone position.

The radiologist marks the surface anatomy on the skin and information of the Aftercare and Com plications depth of the kidney from the skin is given. The patient is haemorrhage, which may be perirenal, causing joint asked to hold his breath in inspiration each time the pain and sometimes a palpable mass as well as signs needle is advanced. Continuing haemorrhage should be treated point of a scalpel blade and then the biopsy needle is by blood transfusion. The obturator is longer than the cannula and Setting up a Drip has a bevelled edge. After introduction of the biopsy Indications needle, the appearance of a large arc of swing of the needle indicates that the kidney has been located. Replacement of fluids (blood products, colloids or the tip of the needle just within the kidney, the patient electrolyte solutions). To provide a route for administering intravenous is pushed in and the cannula is then pushed over the medication or nutrition. No absolute contraindications exist, but particular the site of cannulation is firmly fixed with adhesive care is needed in some circumstances: In presence of plaster. If small veins with inadequate blood flow are blunt dissection of subcutaneous tissue and is under cannulated, inflammation may occur at the venedirect vision. Appearance of inflammation at the site of cannulation is an indication for prompt removal of the cannula. Procedure the local infection will not clear or respond to treatment as long as the foreign material is present. The most convenient site for peripheral cannulation is the non-dominant forearm (left forearm in a right handed An unexplained fever in a patient with a drip is often due to individual and vice versa). Adm inistration of Intravenous Veins of the elbow should be avoided if possible, as Cytotoxics the cannula is difficult to fix firmly, and uncomfortable immobilisation of the joint is required. The dorsum of the administration and management of intravenous the hand is a convenient site. Other sites of cannulation are the jugular, cology, toxicology, and effectiveness of these drugs. Procedure Venepuncture Patient should be adequately informed about the proClothing is removed from the limb and a tourniquet is cedure to be adopted and also of the side effects that may applied to occlude venous return. Cytotoxic the vein is then pierced by moving the needle in the drugs should never be injected into the veins of the leg. A fresh blood count the fluid or blood is usually present in a collapsible should always be obtained before administering plastic bag. Sepsis in presence of the cytotoxics to be used or which is the organ of neutropenia is an emergency and urgent measures excretion for that drug. Presence of infection, whereby administration of the Metabolites of some cytotoxic drugs like ifosfamide cytotoxic drug may be postponed. Extravasation Percutaneous Central Venous Many cytotoxics are very vesicant and if they extravasate they may cause severe tissue damage. If, despite Cannulation careful administration, extravasation does occur, the Central venous pressure is the resultant of venous blood injection is stopped immediately and the following volume, right ventricular function and venous tone. Withdraw any remaining drug by aspirating through with impaired right heart function, is the most common the needle. Analgesics may be administered in the presence of be given through a central line if one is available. Local Reactions It is also used for insertion of a Swan-Ganz catheter Redness and irritation sometimes develop along the vein to monitor the pulmonary artery and left atrial pressure being injected as a local reaction to the drug, especially and also for introduction of intracardiac pacing devices. This may be reduced by Venepuncture should be avoided at any site in which further dilution, achieved, for example, by injecting the there is sepsis. Intravenous hydrocortisone may be used at the clavicular or supraclavicular approaches to the subend of the procedure. A carotid artery aneurysm precludes using the Pain on Adm inistration internal jugular vein on the same side. Some drugs (especially dacarbazine, vinblastine, and mustine) cause muscular and venous pain on adminisProcedure tration. This pain is felt along the vein and not just at Strict aseptic precautions should be observed during the site of the needle, and so is different from that caused the insertion of the cannula. Further dilution or injection into a fast running infusion often alleviates the problem. Catheter through cannula: Cannula on the outside of a needle is placed in the vein and the needle is withMany cytotoxic drugs cause severe emesis. When mandatory to ensure a good antiemetic cover prior to the catheter is in position the cannula is withdrawn.

Patients with a to a wire) is withdrawn, and the catheter advanced suspected potential infection should have an immediate into position. Catheter over guide wire: A flexible guide wire is Infraclavicular subclavian vein: the subclavian vein is inserted into the vein through a needle. After particularly suitable for administering long term removal of the needle the catheter is inserted over parenteral nutrition. It is widely patent even in states of circulatory collapse, so that subclavian venepuncture may provide M ethods of Insertion the only route for rapid infusion. If the Puncture and catheterisation of the subclavian vein patient is conscious the skin should be infiltrated with a is a blind procedure, and so may result in complications, local anaesthetic.

Either the angle of the mandible to behind the middle of the side may be used although the right side is preferable. The needle is attached to a saline filled syringe and inserted below the lower border of the midpoint of the Internal jugular vein: the internal jugular veins run clavicle. The needle tip is advanced close to the underbehind the sternomastoid close to the lateral border of surface of the clavicle, aiming at the suprasternal notch. The vein may be cannulated with a While the needle is advanced, gentle suction should be low incidence of major complications by an approach maintained on the syringe, and a flush of blood indicates well above the clavicle. The cannula is then passed into head down position with the head turned to the opposite the vein.

Preface viivii Discussion To promote effectiveness and minimize possible toxicity pain medication for little dogs buy maxalt 10mg mastercard, the dosage of certain medications must be adjusted in persons with compromised kidney function treatment for dog gas pain generic maxalt 10mg with amex. Convenient and comprehensive evidence-based resources are needed to enable consistent application of such adjustments kneecap pain treatment 10 mg maxalt fast delivery. Means to ensure that patients whose current medications need adjustment are consistently identified also are vitally necessary shoulder pain treatment options discount maxalt 10mg online. Computerized assessment and consequent-directed recommendations concerning drug dosage have proven capable of improving prescribing patterns kingston hospital pain treatment center cheap maxalt american express. A recent meta-analysis that evaluated 26 controlled comparisons of behavioral prescriber changes and/or health outcomes of patients associated with computerized interventions targeted to affect prescribing documented significant benefit of computerized advice by increasing the initial dose pain treatment for pinched nerve order generic maxalt pills, increasing serum drug concentrations, reducing the time to therapeutic stabilization, reducing the risk of toxic drug levels, and reducing the length of hospital stay [38]. The appendant listing was designed to close some identified gaps in information concerning dosage adjustment of medications eliminated by the kidneys. First and foremost, we fully understand and appreciate that no single reference related to medication management in patients with kidney disease can provide truly comprehensive, completely accurate, totally unbiased, and thoroughly evidence-based recommendations. Secondly, our information was largely compiled with use of secondary or tertiary data sources with corroboration of the primary literature. These measures of kidney function thusly were considered essentially interchangeable, as demonstrated in earlier clinical investigations [45], and this bias currently persists in the dosing guidelines used as our foremost source of alternative dosage adjustment recommendations [11]. Lastly, other than an viiiviii Preface informal acceptability survey of clinicians at the University of Colorado Hospital, the utility of this resource has not been clinically tested.

Medical records pain treatment in lexington ky purchase generic maxalt, financial transactions back pain treatment tamil cheap maxalt online, and collections of private electronic 196 13 pain treatment for endometriosis quality 10 mg maxalt. Everyone knows that this hidden data exists (we each contribute to these data collections) pain management treatment for fibromyalgia purchase 10 mg maxalt overnight delivery, that this hidden data is much bigger than the data that we actually see pain treatment for arthritis on the hip 10mg maxalt with visa, and that this data is the basic glue that binds the information universe pain medication for dogs in labor generic maxalt 10mg on-line. Nonetheless, most of the data created for the information universe is considered private. Private data is controlled by a small number of corporations who guard their data against prying eyes, while they use the data, to the extent allowed by law, to suit their own agendas. None of the commercially available deidentification/scrubbing software does a perfect job. These software applications merely reduce the number of identifiers in records; they leave behind an irreducible number of identifying information. If deidentification/scrubbing software actually performed as claimed, removing every identifier and every byte of unwanted data from electronic records, some records might be identified through the use of external database resources that establish identities through nonidentifying details contained in records (vida infra). Big Data managers are highly risk averse and would rather hoard their data than face the risk, no matter how unlikely, of a possible tort suit from an aggrieved individual. Big Data managers are comfortable with restricted data sharing through legal instruments such as data use agreements (see Glossary item, Data sharing). Through such agreements, selected sets of data extracted from a Big Data resource are provided to one or a few entities who use the data for their own projects and who do not distribute the data to other entities. Data deidentification methods, like many of the useful methods in the information field, can be patented. Some of the methods for deidentification have fallen under patent restriction or have been incorporated into commercial software that is not freely available 45 to data managers. For some data managers, royalty and license costs are additional reasons for abandoning the deidentification process. Big Data managers are not fully convinced that deidentification is possible, even under ideal circumstances. It may seem impossible, but information that is not considered identifying may actually be used to discover the name of the person linked to deidentified records. Mischievous schemes to thwart the deidentification process all work through one simple trick: access to an external database that contains identified information linked to nonidentifying data. Here is an example whereby the trick works: suppose I have a data set composed of deidentified records that includes a field for gene variants and another field for criminal record. The data resource is being used for many analytic purposes, including efforts to determine whether there is an association between certain gene variants and certain types of criminal behavior. Let us imagine that there is a public database containing identified records that contain the same kinds of gene variant data (see Glossary item, Public data). All of the identified records in this database were obtained from volunteers who wished to participate in studies that might help identify their own ancestors. When he finds a match in gene variants, he acquires the name associated with the gene variant in the public database, and that name will correspond with the person whose criminal record is included in the deidentified database. Basically, deidentification is easy to break when deidentified data can be linked to a name in an identified database containing fields that are included in both databases. This is the common trick underlying virtually every method designed to associate a name with a deidentified record. In the example provided, it may be impossible to find an exact match between the gene variants in the deidentified database and the gene variants in the identified database. Data managers who provide deidentified data sets to the public must worry whether there is, or ever will be, an available identified database that can be used to link fields, or combinations of fields, to their deidentified data, and thus linking their records to the names of individuals. This worry weighs so heavily on data managers and on legal consultants for Big Data resources that there are very few examples of publicly available deidentified databases. Everyone in the field of Big Data is afraid of the legal repercussions that will follow when the confidentiality of their data records is broken. These issues are often intractable because each side has a legitimate claim to their own preferences (businesses need to make profit and individuals need some level of privacy). At some point, every Big Data manager must create a privacy policy and abide by his or her own rules. It has been my experience that legal problems arise when companies have no privacy policy, have a privacy policy that is not well documented, have a privacy policy that is closed to scrutiny, have a fragmented privacy policy, or fail to follow their own policy. Companies are much more likely to get into trouble for ignoring their own policies than for following an imperfect policy. Every Big Data project should make the effort to produce a thoughtful set of policies to protect the confidentiality of its records and the privacy of data subjects. These policies should be studied by every member of a Big Data project, and should be modified as needed, and be reviewed at regular intervals. If you are a Big Data manager endowed with an overactive imagination, it is possible to envision all types of unlikely scenarios in which confidentiality can be breached. The researchers tried but failed to make headway linking genes sampled from the Havasupai tribe with cases of diabetes. The gene samples were subsequently used for ancillary studies that included schizophrenia and for studies on the demographic trends among the Havasupai. In their opinion, these studies did not benefit the Havasupai and touched upon questions that were considered embarrassing and taboo, including the topic of consanguineous matings and the prevalence rates of mental illnesses within the tribe. In 2004, the Havasupai tribe filed a lawsuit indicating lapses in the informed consent process, violation of civil rights, violation of confidentiality, and unapproved use of the samples. The case was dismissed on procedural grounds, but was reinstated by the Arizona Court of 209 Appeals in 2008. Arizona State University agreed to pay individuals in the Havasupai tribe a total of $700,000. This award is considerably less than the legal costs already incurred by the university. If the Havasupai tribe won anything in this dispute, it must have been a Pyrrhic victory. Because the case was settled out of court, no legal decision was rendered and no clarifying precedent was established. Though I am not qualified to comment on the legal fine points, several of the general principles related to the acquisition and use of data are relevant and can be discussed as topics of general interest. Laypersons should not be put into a situation wherein they must judge the value of research goals. By signing consent, the signator indicates that he or she is aware of the potential harm from the research and agrees to accept the risk. In the case of samples or data records contributed to a Big Data resource, consenters must be warned, in writing, that the data will be used for purposes that cannot be specified in the consent form. Most consent is obtained to achieve one primary purpose, and this purpose is customarily described briefly in the consent form. The person who consents often wants to know that the risks that he or she is accepting will be compensated by some potential benefit to society. There is no ethical requirement that binds scientists to conduct their research for the sole benefit of one group of individuals. A good consent form will clearly state that research conducted cannot be expected to be of any direct value to the consenter. Finally, the consent form should include all of the potential harms that might befall the consenter as a consequence of his or her participation. It may be impossible to anticipate every possible adverse consequence to a research participant. In this case, the scientists at Arizona State University did not anticipate that the members of the Havasuapai tribe would be harmed if their gene data was used for ancillary research purposes. I would expect that the researchers at Arizona State University do not believe that their research produced any real harm. Had the original consent form listed all of the potential harms, as perceived by the Havasupai, then the incident could have been avoided. Had any members of the Havasupai tribe voiced concerns over the unspecified medical and behavioral disorders mentioned in the consent form, then the incident could have been avoided. The Havasupai did not understand how scientists use information to pursue new questions. The board of regents did not understand the harms that might occur when data is used for legitimate scientific purposes. The take-home lesson for data managers is the following: to the extent humanly possible, ensure that consent documents contain a complete listing of relevant adverse consequences. In some cases, this may involve writing the consent form with the assistance of members of the group whose consent is sought. The future directions of Big Data will be strongly influenced by social, political, and economic forces. Will scientists archive their experimental data in publicly accessible Big Data resourcesfi Will scientists adopt useful standards for their operational policies and their datafi How scientists use data over the next few years may provide the strongest argument for or against the proliferation of Big Data resources. The purpose of Big Data was rationalized under the following eight distinct hypotheses. Gumshoe hypothesis: Hoarding information about individuals for investigative purposes. In this hypothesis, Big Data exists for private investigators, police departments, and 201 202 14. The modern private eye has profited from Big Data, as have law enforcement officers. It is unsettling that savvy individuals have used Big Data to harass, stalk, and breach the privacy of other individuals. These activities have left some individuals dreading future sanctioned or unsanctioned uses of Big Data. The expectation that Big Data will serve to prevent crime, bring criminals to justice, and enhance the security of law-abiding citizens has not fully engaged the public consciousness. Big Brother hypothesis: Collecting information about a population of individuals to control every member of the population. Modern governments obtain data from surveillance cameras, arrest records, wiretaps and sophisticated eavesdropping techniques, census records, tax records, accounting records, driving records, public health records, and a wide variety of information collected in the normal course of official operations. When a government sponsors Big Data collections, there will always be some anxiety that the Big Data resource will be used to control the public, reducing our freedoms of movement, expression, and thought. On the plus side, such population-wide studies may eventually reduce the incidence of crime and disease, make driving safer, and improve society overall. Borg hypothesis: Collecting information about a population of individuals to learn everything about the population. I assume that if you are reading this book on Big Data, you most likely are a Star Trek devotee and understand that the Borg are a race of collectivist aliens who travel through galaxies, absorbing knowledge from civilizations encountered along the way. Big Data analysts predict and control the activities of populations: how crowds move through an airport, when and where traffic jams are likely to occur, when political uprisings will occur, how many people will buy tickets for the next 3D movie production, or how fast the next flu epidemic will expand. With cloud computing, search engines that encompass the Web, and protocols for retrieving our own information upon request, Big Data becomes an infinite storage attic. Find these: movies playing now at the local cineplex, Amtrak schedule for the northeast corridor of the United States, cost of tickets to a Broadway play, updated locations of spouse and children, average weight of male elephants, and in-air flight time to New Delhi. According to the scavenger hunt hypothesis, Big Data is everything you ever wanted to know about everything. Egghead hypothesis: Collecting information to draw generalized scientific conclusions. To fully understand the beauty of the egghead hypothesis, a preliminary explanation of the purpose of science is in order. Science is a method whereby we develop generalizations about the nature of our world and of the universe by observing individual objects in the universe under various naturally occurring or experimentally contrived conditions. For example, when an object such as an apple or a lead weight is dropped from a height, we can watch it fall, measure the time for the descent, determine that the apple and the lead weight dropped at the same rates throughout their respective descents, and develop a formula that relates the distance dropped to the square of the interval time for the drop. Once done, and confirmed on other objects, we know a great deal about how everything falls (not just one apple and one lead weight). When a scientist extracts Big Data collected on a large set of individuals, his or her purpose is to quickly move from the level of specificity. For example, if a scientist is studying the incubation period for West Nile virus, when humans are infected by a mosquito bite, the scientist will want to collect as many infection records as possible, with detailed information documenting the time that infection occurred and the time that symptoms emerged. The records will be identified, at some time in the data collection process, with information that links the record to a particular person. The last thing that the scientist is interested in is the identity of the patient.
