The corresponding specificity rates 211 The Michigan Alcoholism Screening Test, were 96 and 85 percent, respectively. It consists of 25 yes/no questions 212 concerning drinking behavior and alcohol- individuals without addiction. The instrument can be self- administered or administered in an interview reliability in inmate populations, its validity in format. The Drug Abuse Screening Test was developed in 1982 to screen for lifetime risky drug use (excluding nicotine and alcohol) and assess * 214 Other variations of the instrument exist, including a addiction in adult populations. Although it is copyrighted, the instrument is available for use 217 Many instruments have been developed to by clinicians, educators and researchers. Researchers continue to combine, restructure and create Populations and Settings Served. This shorter version is more accurate at identifying risky users than 227 individuals with addiction.

This control of healthcare costs can be velops, markets, distributes, and generates revenue attributed, at least in part, to the dramatic growth for products. This chapter will introduce basic concepts fee-for-service to a managed care environment has in managed care, discuss the impact of managed affected every aspect of the healthcare system, in- care on the pharmaceutical industry, and conclude cluding the pharmaceutical industry. Managed care with a discussion of emerging trends in managed organizations have helped to bring healthcare costs care and howthey may impact the pharmaceutical under control through a variety of strategies, in- industry in the future. Although satisfied with the results of slowed increases in healthcare The basic concepts of managed care have evolved costs, purchasers and consumers have been less and are continuing to evolve over time. To under- satisfied with restricted access to providers and stand this evolution, a brief historical perspective is benefit limitations and restrictions. As a result, pur- presented first, followed by discussions of the lan- chasers and consumers are pressuring managed guage and principles of managed care.

For example, Intrinsic to the principles of managed care is the managed care plans have driven pharmaceutical conflict between the desire to control costs and the costs down by demanding economic proof of a desire to promote quality of care.

Clearly, the impetus has been the ment programs to provide comprehensive medical ability of managed care plans to reduce healthcare care and improve patient outcomes at a lower cost expenditures, which is accomplished by shifting (Schulman et al 1996). Today, virtually all managed the focus of healthcare away from incident-driven care plans offer a disease management program for delivery to preventive and coordinated care.

The medical physics laboratory is usually a slightly expanded office and may comprise a small workbench discount 250 mg cephalexin fast delivery, any necessary storage space and one or more computer terminals buy generic cephalexin 250 mg online. The area would normally be considered ‘non-active’ and therefore have no specific radiation protection requirements. The detector arrays are mounted on a gantry and make a complete or part circle around the patient, enabling volume detection. It also has higher spatial resolution because it provides information about the origin of the annihilation. An average facility will include: (a) Rooms for reception: —Scanner, control, waiting, injection, blood testing, reporting and admin- istration rooms. Staff requirements (a) Medical staff: —One or two doctors; —One or two technologists; —One nurse. After defining the level of service and required equipment, the director of the service should submit a specification (Section 4. At this stage, it is extremely important to plan the training of medical staff, technicians, physicists and engineers, arrange service contracts, and make provisions for the future updating of hardware and software. The following can take place once installation has been completed: —Acceptance testing; —Phantom studies; —Providing physicians and patients with information; —Training of technical staff. The following can take place after operation has commenced: —Communication with clinicians; —Evaluation of results; —Follow-up; —Joint conferences; —Continued future technical and medical education. A cyclotron is composed of a pair of magnets, holding a vacuum tank in which two or four D shaped electrodes are fixed. The particles are attracted or propelled by the alternatively charged D electrodes to gain higher energy and circle in the middle of the tank under the control of the magnets. On gaining energy they move in a larger radius until they reach the desired energy. The accelerated particles bombard the target material to produce the desired new radionuclides. Basic concerns Although the principle of the cyclotron has not changed much since it was first introduced by Sir Ernest Lawrence in 1932, it is still a very expensive and complex device that requires a great deal of attention before installation can commence. Questions that require answers are: (a) Is the cost of a cyclotron service, rather than the alternatives, really justified? One choice is between a cyclotron with self-shielding or a cyclotron without self-shielding. A decision also has to be made on the type of radionuclide produced and on whether a gas or a liquid target is preferable. Most of the preparatory measures, including the requirements for space, staff, environment and legislation, are discussed in Section 3. Establishment of a cyclotron practice As a first step, it is vital to define the need and scope of the service. The cyclotron and affiliated hot laboratory are needed in those centres that are committed to research, either on in vivo biochemistry and physiology or on the development of radiopharma- ceuticals and design of new drugs. The evaluation of a cyclotron should take into account the following factors: 96 3. In negotiating purchases and contracts, attention should be paid to the service, warranty and supply of special consumable goods and spare parts, as well as special tools for quality control, service and installation. Acceptance tests include those on production yield, stability and reliability of operation. Training in cyclotron, chemical modules, hot laboratory and quality control should be provided for operators, physicists, service engineers and radiochemists. The radiochemist and/or radiopharmacist play a vital role in radiochemistry and quality control laboratories. To circumvent this problem, it is recommended that a molecular biology laboratory be divided into three distinct areas as described below. Caution should be taken when using numerous amplifications of the same primer pair system. The following precautions will eliminate the risk of false positives in the context of diagnostic assays. Reactions prior to (Areas 1 and 2) and following (Area 3) amplification should be separated physically. Similarly, it is unwise to take devices such as pipettors into the containment area after use on amplified material. Separate sets of automatic pipettors, disposable pipettes, a microcen- trifuge, tubes and gloves should be kept in each area. Positive displacement pipettors and plugged tips, to form an aerosol barrier, should be used in Areas 1 and 2. Positive displacement pipettes are recommended to eliminate the cross-contamination of samples by pipetting devices. It is advisable to record the reagent lots used so that if carry-over occurs it can be more easily traced. Laboratory precautions in the handling of radioactivity should be incor- porated (Area 3). For use as a positive control, a sample should be selected that amplifies weakly but consistently.

Once again cheap 750 mg cephalexin free shipping, one must always consider ectopic pregnancy in the differential when evaluating the pregnant patient with vaginal bleeding discount 250mg cephalexin mastercard. The patient with unilateral pelvic pain and vaginal bleeding needs thorough evaluation to differentiate early abortion from ectopic pregnancy. Definitions • Threatened Abortion—Uterine bleeding in the first 20 wk of pregnancy without any passage of tissue or cervical dilatation. These patients present with vaginal bleeding in the first half of pregnancy 90% of the time. Diagnostic Evaluation • Standard laboratory testing to be obtained in the setting of vaginal bleeding in the first half of pregnancy should include all of the following. Patients with a visualized intrauterine pregnancy with a closed cervical os can be considered to have a threatened abortion. Correlation of ultrasound results with the patient’s history and physical findings will allow the type of abortion to be identified. They should be instructed to return to the Emergency Department if vaginal bleeding increases and/or returns, if they notice any passage of tissue, or if they de- velop significant pelvic pain or fever. The patient should be placed on pelvic rest which means no intercourse, no douching and physical activity. Vaginal Bleeding in the Second Half of Pregnancy Vaginal bleeding after 20 wk of gestation can present a complicated clinical management situation with the lives of the mother and fetus often both in serious jeopardy. Abruptio Placentae/Placental Abruption • Definition—The complete or partial placental separation from the decidua basalis (uterine implantation site) after 20 wk of gestation. When this separation develops, 7 blood vessels are ruptured leading to hematoma formation which leads to significant hemorrhaging and fetal hypoxia. Incidence • Abrubtio placentae occurs in approximately 1/100 pregnancies and is the cause of approximately 14% of all stillbirths in the United States. Clinical Presentation • Variability of clinical presentation is related to the quantity and location of hemor- rhaging. The patient may complain of back and/or abdominal pain, and the pain is usually relatively sudden in its onset and constant in nature. Early awareness of this possibility may become apparent if the patient is noted to have excessive hemorrhaging at venopuncture or intravenous access sites, mucosal/gingival hemorrhaging, easy bruising and/or hematuria. Emergency Department Management • Intravenous access should be immediately obtained. Causes of vaginal bleeding in the 2nd half of pregnancy • Abruptio placentae/placental abruption • Placenta previa • Premature labor • Premature rupture of membranes • Lesions of the cervix and lower genital tract • Uterine rupture • Vasa previa Table 7A. Risk factors for placental abruption • Hypertension • Preeclampsia • History of prior placental abruption • Trauma • Cigarette smoking • Increasing maternal age 7 • High multiparity • Illicit drug use (cocaine abuse) • Excessive alcohol consumption • A Kleihauer-Betke test should also be obtained to detect fetal cells in the maternal circulation. When abruption is visualized on ultrasound it appears as a hypoechoic area between the placenta and the uterine wall. In the presence of more severe placental abruption, expedited vaginal delivery or emergent cesarean section may be necessary. Placenta Previa Definition • Placenta previa describes a situation where any part of the placenta implants in the lower uterine segment and be associated with a high risk of significant serious mater- nal hemorrhaging. Risk factors for placenta previa • Multiparity • Multiple gestation pregnancies • Previous cesarean section • Prior uterine scar for any reason • Increasing maternal age • Previous abortion • Prior placenta previa • Diabetes mellitus • Erythroblastosis fetalis • Any process that increases placental size • Marginal Placenta Previa—The placenta is located adjacent to the patient’s internal os but is not covering it. Incidence • Placenta previa occurs in approximately 1/200 pregnancies in the United States. Emergency Department Management • When placenta previa is clinically suspected emergent obstetrical consultation should be obtained. Hyperemesis Gravidarum • It is normal to have some degree of nausea and vomiting for most patients during the course of pregnancy and these episodes are especially frequent in first 12 wk. Frequently used antiemetics are promethazine (phenergan), prochlorperazine (compazine) and trimethobenzamide (tigan). Pregnancy Induced Hypertension Definition • Hypertension in pregnancy is defined as a blood pressure ≥140/90 in the second half of pregnancy in a previously normotensive patient. There is a significant mortality rate for both the mother and the fetus with eclampsia. Despite the chronic nature of this underlying condition, preeclampsia and eclampsia can both can occur in these patients. Differential diagnosis for severe nausea and vomiting in early pregnancy • Hyperememesis gravidarum • Hepatitis • Viral gastroenteritis • Appendicitis • Partial intestinal obstruction • Diabetic ketoacidosis • Molar pregnancy/gestational trophoblastic disease • Urinary tract infection • Multiple gestation pregnancy • Migraine • Gallbladder disease • Transient hypertension is hypertension that develops in the latter half of the preg- nancy. It is very mild hypertension that doesn’t compromise the pregnancy and spon- taneously regresses in the postpartum period. If the fetal gestational age is >24 wk, then fetal monitoring and biophysical profile should be obtained. Emergency Department Management • When blood pressure is noted at this level it should be lowered with either intravenous hydralazine or labetalol with a goal of a systolic pressure of 140-150 and a diatolic pressure of 90-100 mm Hg. Risk factors for the development of preeclampsia and eclampsia • Chronic hypertension • Primigravida • Family history of preeclampsia / eclampsia • Multiple gestation pregnancy • Extremes of age • Molar pregnancy • Diabetes mellitus • Chronic renal disease • Infrequent or nonexistent prenatal medical care • Magnesium sulfate is also administered to these patients to prevent seizures (eclamp- sia) from developing.
