Mechanisms of Prescription Drug Diversion among Drug-Involved Club and Street-Based Populations

OBJECTIVE: Prescription drug diversion involves the unlawful channeling of regulated pharmaceuticals from legal sources to the illicit marketplace, and can occur along all points in the drug delivery process, from the original manufacturing site to the wholesale distributor, the physician\u27s office, the retail pharmacy, or the patient. However, empirical data on diversion are limited. METHOD: In an attempt to develop a better understanding of how specific drug-using populations are diverting prescription opioids and other medications, or obtaining controlled drugs that have already been diverted, qualitative interviews and focus group data were collected on four separate populations of prescription drug abusers in Miami, Florida--club drug users, street-based illicit drug users, methadone maintenance patients, and HIV positive individuals who abuse and/or divert drugs. RESULTS: Sources of abused prescription drugs cited by focus group participants were extremely diverse, including their physicians and pharmacists; parents and relatives; doctor shopping ; leftover supplies following an illness or injury; personal visits to Mexico, South America and the Caribbean; prescriptions intended for the treatment of mental illness; direct sales on the street and in nightclubs; pharmacy and hospital theft; through friends or acquaintances; under-the-door apartment flyers advertising telephone numbers to call; and stealing from grandma\u27s medicine cabinet. CONCLUSION: While doctor shoppers, physicians and the Internet receive much of the attention regarding diversion, the data reported in this paper suggest that there are numerous active street markets involving patients, Medicaid recipients and pharmacies as well. In addition, there are other data which suggest that the contributions of residential burglaries, pharmacy robberies and thefts, and sneak thefts to the diversion problem may be understated

The Diversion of Prescription Drugs by Health Care Workers in Cincinnati, Ohio

Data are reported from drug diversion cases involving health care workers who were investigated by the Cincinnati Police Division Pharmaceutical Diversion Squad over an 11-year period. This type of information is rarely available because few U.S. police jurisdictions dedicate resources to prescription drug diversion surveillance. Data from 1992 through 2002 show that opioids were the drugs most commonly diverted by health care workers, followed by benzodiazepines. Nurses, nursing assistants, and medical assistants were involved in almost three quarters of all cases. Hospitals were the most common sources of complaint to police, followed by pharmacies. Health care professional associations are advised to promote greater awareness of drug misuse and dependence concerns among their memberships, and health care facilities that stock pharmaceuticals liable for misuse and diversion are advised to increase the security of their supplies

Spotting the diffusion of New Psychoactive Substances over the Internet

Online availability and diffusion of New Psychoactive Substances (NPS) represent an emerging threat to healthcare systems. In this work, we analyse drugs forums, online shops, and Twitter. By mining the data from these sources, it is possible to understand the dynamics of drugs diffusion and their endorsement, as well as timely detecting new substances. We propose a set of visual analytics tools to support analysts in tackling NPS spreading and provide a better insight about drugs market and analysis

Patterns of Prescription Opioid Abuse and Comorbidity in an Aging Treatment Population

Very little is known about the impact of age and gender on drug abuse treatment needs. To examine this, we recruited 2,573 opioid-dependent patients, aged from 18 to 75 years, entering treatment across the country from 2008 to 2010 to complete a self-administered survey examining drug use histories and the extent of comorbid psychiatric and physical disorders. Moderate to very severe pain and psychiatric disorders, including polysubstance abuse, were present in a significant fraction of 18- to 24-year-olds, but their severity grew exponentially as a function of age: 75% of those older than 45 years had debilitating pain and psychiatric problems. Women had more pain than men and much worse psychiatric issues in all age groups. Our results indicate that a one-size-fits-all approach to prevention, intervention, and treatment of opioid abuse that ignores the shifting needs of opioid-abusing men and women as they age is destined to fail

The Black Box of Prescription Drug Diversion

A variety of surveys and studies are examined in an effort to better understand the scope of prescription drug diversion and to determine whether there are consistent patterns of diversion among various populations of prescription drug abusers. Data are drawn from the RADARS System, the National Survey of Drug Use and Health, the Delaware School Survey, and a series of quantitative and qualitative studies conducted in Miami, Florida. The data suggest that the major sources of diversion include drug dealers, friends and relatives, smugglers, pain patients, and the elderly, but these vary by the population being targeted. In all of the studies examined, the use of the Internet as a source for prescription drugs is insignificant. Little is known about where drug dealers are obtaining their supplies, and as such, prescription drug diversion is a black box requiring concentrated, systematic study

Multiple Determinants of Specific Modes of Prescription Opioid Diversion

Numerous national surveys and surveillance programs have shown a substantial rise in the abuse of prescription opioids over the past 15 years. Accessibility of these drugs to non-patients is the result of their unlawful channeling from legal sources to the illicit marketplace (diversion). Empirical data on diversion remain absent from the literature. This paper examines abusers\u27 sources of diverted drugs from two large studies: 1) a national sample of opioid treatment clients (N=1983), and 2) a South Florida study targeting diverse populations of opioid abusers (N=782). The most common sources of diverted medications were dealers, sharing/trading, legitimate medical practice (e.g., unknowing medical providers), illegitimate medical practice (e.g., pill mills), and theft, in that order. Sources varied by users\u27 age, gender, ethnicity, risk-aversiveness, primary opioid of abuse, injection drug use, physical health, drug dependence, and either access to health insurance or relative financial wealth. Implications for prescription drug control policy are discussed

Compliance to Bleach Disinfection Protocols among Injecting Drug Users in Miami

Bleach cleansing of injection equipment has been recommended to reduce the risk of human immunodeficiency virus (HIV) transmission associated with the reuse of injection equipment by injecting drug users (IDUs). We evaluated the recall and performance of the most commonly recommended bleach cleansing procedure of two complete fillings of the syringe with bleach, followed by two complete fillings with rinse water, and not putting used bleach and water back into source containers. IDUs were taught this procedure on enrollment in an HIV prevention demonstration project in Dade County, Florida. During follow-up session 6-12 months after initial training, the knowledge and ability of IDUs to perform bleach cleansing were assessed by trained observers using a standardized method. In 1988-90, we assessed the knowledge and ability of 450 IDUs to perform the bleach cleansing procedure taught at enrollment. More than 90% of IDUs assessed performed the basic steps. However, only 43.1% completely filled the syringe with bleach and only 35.8% completely filled the syringe with bleach at least twice. Substantial proportions of IDUs did not perform all the steps of the previously taught bleach cleansing procedure. Compliance decreased as the number of steps required was increased. This limited compliance may make bleach cleansing less effective and suggests that some IDUs may fail to adequately disinfect injection equipment and therefore sterile needles and syringes are safer than bleach-cleansed ones. Compliance testing can help assess the effectiveness of HIV prevention programs. © 1994 Raven Press, Ltd., New York

Relationship between therapeutic use and abuse of opioid analgesics in rural, suburban, and urban locations in the United States

SUMMARY Purpose The goal of these studies was to determine the relationship between prescribed use of opioid analgesics and their non-medically related use (abuse) at a regional level across the country. Methods To gather information about prescription drug abuse, we asked 233 drug abuse treatment specialists to provide us Quarterly reports on the number of cases of prescription opioid analgesic abusers who used opioid analgesics to get high in the past 30 days. Results and Conclusions We found that there was a very strong correlation between therapeutic exposure to opioid analgesics, as measured by prescriptions filled, and their abuse. There were, however, geographical loci that represented outliers in which abuse was disproportionately high relative to therapeutic use (>95th percentile), most of which were in very small urban, suburban, and rural areas. The rank order of abuse shows that buprenorphine products, extended release (ER) oxycodone and methadone are the most intensely abused prescription opioid analgesics, with hydrocodone the least abused, when the data are corrected for degree of exposure, i.e., cases/1000 persons filling a prescription. If, on the other hand, one uses the number of cases/100 000 population, hydrocodone ranked as high as ER oxycodone and all other drugs grouped together at very low levels of abuse. Since the latter conclusion ignores therapeutic exposure, we conclude that the rate of abuse of highly efficacious opioid analgesics is best expressed as cases of abuse/1000 persons filling a prescription, which yields the best possible estimate of the risk-benefit ratio of these drugs

Antifungal prophylaxis in chemotherapy-associated neutropenia: a retrospective, observational study

<p>Abstract</p> <p>Background</p> <p>In August 2002, the antifungal prophylaxis algorithm for neutropenic hematology/oncology (NHO) patients at the Medical Center was changed from conventional amphotericin (AMB) to an azole (AZ) based regimen (fluconazole [FLU] in low-risk and voriconazole [VOR] in high-risk patients). The aim of our study was to compare outcomes associated with the two regimens, including breakthrough fungal infection, adverse drug events, and costs.</p> <p>Methods</p> <p>Adult, non-febrile, NHO patients who received prophylactic AMB from 8/01/01-7/30/02 or AZ from 8/01/02-7/30/03 were retrospectively evaluated.</p> <p>Results</p> <p>A total of 370 patients (AMB: n = 181; AZ: n = 216) associated with 580 hospitalizations (AMB: n = 259; AZ: n = 321) were included. The incidence of probable/definite breakthrough Aspergillus infections was similar among regimens (AMB: 1.9% vs AZ: 0.6%; p=0.19). A greater incidence of mild/moderate (24.7% vs. 5.3%; p < 0.0001) and severe renal dysfunction (13.5% vs. 4.4%; p < 0.0012) was observed with AMB. In contrast, patients treated with VOR were found to have an increased rate of severe hepatic toxicity (32.5%) compared with patients treated with either AMB (22.6%) or FLU (21.4%) (p = 0.05). While the AZ period was associated with a >$9,000 increase in mean total costs/hospitalization, the mean acquisition cost associated with AZ was only$947/hospitalization more than AMB.</p> <p>Conclusion</p> <p>While an AZ-based regimen is associated with increased cost, the reduced rate of nephrotoxicity and availability of oral dosage forms, suggests that azoles be used preferentially over AMB. However, an increased rate of severe hepatic toxicity may be associated with VOR.</p

Suicides, poisons and the materially possible: The positive ambivalence of means restriction and critical–critical global health

Developing an object-oriented perspective on suicide, in this article the author challenges critical global health scholarship and sociological theories of ambivalence by showing how a focus on ‘materially possible’ suicide prevention can offer culturally relevant solutions to a suicide epidemic in a resource-poor setting. Taking the example of pesticide regulation in Sri Lanka, he demonstrates why, in theoretical terms, banning toxic pesticides has coherence in a local poison complex that renders suicide available to people as a cultural practice. While writers in the field of critical global health have been suspicious of ‘magic-bullet’ interventions such as means restriction because such policies reportedly overlook the social complexity of problems such as suicide, the author argues that what is materially possible is often of merit because it renders graspable an otherwise deeply contingent and variegated problem. He further argues that critical global health can view the ambivalent costs and benefits of materially possible, magic-bullet interventions as a positive rather than negative offshoot of global health
