ABSTRACT

BACKGROUND: Since prices of imatinib (Gleevec) remain high, patients on oral chemotherapy are looking for alternative methods to access this life-saving medication. We assessed the accessibility of imatinib through online pharmacies and analyzed each website for medication safety, price, and marketing tactics. METHODS: We searched the term "buy imatinib online" using 4 commonly used internet search engines (Google, Bing, Yahoo!, and DuckDuckGo) and screened web pages displayed in the first 10 pages. Websites were included if they were published in English, sold imatinib, were free to access, and offered shipping in the United States. Websites were classified using LegitScript's categorization as "certified," "unclassified," "unapproved," or "rogue." We analyzed information on websites' patient safety characteristics, marketing techniques, pricing, domain registration information, and IP addresses. RESULTS: Of the 44 online pharmacies identified, only 3 (7%) were certified, and the remainder were classified as rogue (52%; n=23), unapproved (30%; n=13), or unclassified (11%; n=5). Thirteen online pharmacies (30%; 9 rogue, 4 unclassified) sold imatinib without a prescription. Nearly one-quarter (n=10) of online pharmacies selling imatinib did not include drug-related warnings on their websites, and nearly half (n=21) did not limit the purchasable quantity. More than three-quarters (n=34) of online pharmacies selling imatinib did not offer pharmacist consultations, even though nearly all websites extended offers to speak with sales associates (91%; n=40). Most online pharmacies selling imatinib claimed price discounts (95%; n=42), but fewer provided bulk discounts (23%; n=10) or coupons (34%; n=15). One-third of rogue pharmacies selling imatinib (n=7) claimed to be registered or accredited on their websites. CONCLUSIONS: The lack of safety measures taken by illegitimate online pharmacies endangers patient safety because they allow patients to purchase imatinib without appropriate evaluation for response, drug interactions, and adverse effects. Healthcare providers need to be aware of this practice and should assure patient access to imatinib through safe and legitimate pharmacies.

ABSTRACT

OBJECTIVES: Adderall (amphetamine-dextroamphetamine) is a controlled substance with harmful adverse effects if abused or misused. We assessed the availability of Adderall from common search engines, and evaluated the safety and marketing characteristics of online pharmacies selling Adderall. DESIGN: Cross-sectional study. SETTING AND PARTICIPANTS: From December 2019 to February 2020, the phrase "buy Adderall online" was queried in four search engines: Google (N = 100), Bing (N = 100), Yahoo (N = 50) and DuckDuckGo (N = 50). Online pharmacies that claimed to sell Adderall and had unique Uniform Resource Locators, were active, free-access, and in English language were included. OUTCOME MEASURES: Online pharmacies were categorized as rogue, unclassified, or legitimate on the basis of LegitScript classifications. Safety and marketing characteristics, and costs were collected. RESULTS: Of the 62 online pharmacies found to sell Adderall, 61 were rogue or unclassified. Across all rogue and unclassified online pharmacies, prescriptions were not required (100%), pharmacist services were not offered (100%), and quantity limits were not placed on the number of Adderall purchases (100%). Rogue and unclassified online pharmacies appealed to cost, offering price discounts (61%), bulk discounts (67%), and coupon codes (70%). Contrary to their claims, cheaper prices were available for all formulations and dosages of Adderall from GoodRx than from these online pharmacies. Rogue and unclassified online pharmacies promoted and enabled the illicit purchase of Adderall, appealing to privacy (74%), offering purchase through cryptocurrency (74%), and claiming registration or accreditation of their sites (33%). CONCLUSION: Rogue online pharmacies are pervasive in search engine results, enabling the illicit purchase of Adderall without a prescription. Consumers are at risk of purchasing Adderall, a medication with high abuse potential, from unsafe sources. Law enforcement, regulatory agencies, and search engines should work to further protect consumers from unregistered and illegitimate online pharmacies selling Adderall.

ABSTRACT

BACKGROUND: Less than half of patients with cardiometabolic disease consistently take prescribed medications. While health insurers and some delivery organizations use claims to measure adherence, most clinicians do not have access during routine interactions. Self-reported scales exist, but their practical utility is often limited by length or cost. By contrast, the accuracy of a new 3-item self-reported measure has been demonstrated in individuals with HIV. We evaluated its concordance with claims-based adherence measures in cardiometabolic disease. METHODS: We used data from a recently-completed pragmatic trial of patients with cardiometabolic conditions. After 12 months of follow-up, intervention subjects were mailed a survey with the 3-item measure that queries about medication use in the prior 30 days. Responses were linearly transformed and averaged. Adherence was also measured in claims in month 12 and months 1-12 of the trial using proportion of days covered (PDC) metrics. We compared validation metrics for non-adherence for self-report (average <0.80) compared with claims (PDC <0.80). RESULTS: Of 459 patients returning the survey (response rate: 43.5%), 50.1% were non-adherent in claims in month 12 while 20.9% were non-adherent based on the survey. Specificity of the 3-item metric for non-adherence was high (month 12: 0.83). Sensitivity was relatively poor (month 12: 0.25). Month 12 positive and negative predictive values were 0.59 and 0.52, respectively. CONCLUSIONS: A 3-item self-reported measure has high specificity but poor sensitivity for non-adherence versus claims in cardiometabolic disease. Despite this, the tool could help target those needing adherence support, particularly in the absence of claims data.

ABSTRACT

OBJECTIVE: To determine the prevalence of and factors associated with dispensing antibiotics without a prescription in online and community pharmacies in China. METHODS: We conducted a nationwide cross-sectional study of online and community pharmacies in 27 cities and counties in nine provinces in China (selected by multistage sampling) from July 2017 to December 2018. We assessed sale of antibiotics without a prescription and quality of pharmacy services through simulated clients who asked to buy specific antibiotics. We compared the prevalence of sales between online and community pharmacies, and between location and features of community pharmacies. FINDINGS: Of 220 online and 675 community pharmacies, 174 (79.1%) and 586 (86.8%) sold antibiotics without a valid prescription, respectively. About half of the online pharmacies had a notice on their website about the illegality of selling prescription-only medicines without a prescription while none of the community pharmacists had. More online pharmacies without this notice dispensed antibiotics without a valid prescription (P < 0.001). Antibiotics' sale without a prescription was significantly less prevalent in provincial capital cities (71.6%; 161/225) than prefectural-level cities (95.1%; 214/225) and counties (93.8%; 211/225; P < 0.001). Most pharmacy staff did not ask for important information from clients before dispensing the antibiotic or provide them with necessary information about the antibiotic. CONCLUSION: Given the high proportion of sales of prescription-only medicines without a prescription, there is a need to strengthen enforcement of regulations, improve public education on antibiotics, train pharmacy staff and consolidate public involvement in antibiotic stewardship in retail pharmacies in China.

ABSTRACT

BACKGROUND: High cost of prescription medications presents a challenging issue for older patients with multimorbidities. Topical 5-fluorouracil (5-FU) is an effective treatment for actinic keratoses (AK), a highly prevalent condition among elderly populations, but it is often associated with unpredictable retail prices and high out-of-pocket costs. One online pharmacy offers branded prescription medications at fixed, low prices, but it may be less accessible to older patients for numerous reasons. OBJECTIVE: To determine if the number of patients receiving topical 5-FU from an online pharmacy is proportionate to the national data on expected payment types for patients prescribed topical 5-FU for AK. METHODS: We conducted a cross-sectional study using weighted pooled data from the National Ambulatory Medical Care Survey (NAMCS) on topical 5-FU prescriptions for AK from 2007-2016. Data regarding online pharmacy use were provided by Dermatology.com for the year 2019. RESULTS: Among patients with AK prescribed topical 5-FU, the most prevalent payment source was Medicare (54%) followed by private insurance (40%). On the online pharmacy, the majority of patients had commercial insurance (71%) followed by Medicaid (12%). LIMITATIONS: Data from Dermatology.com are limited. CONCLUSIONS: Lower-cost medications from the online pharmacy site may improve adherence and outcomes in older adults and decrease total cost associated with AK treatment. However, the online pharmacy is underutilized by this population. J Drugs Dermatol. 2020;19(4): doi:10.36849/JDD.2020.4690.

ABSTRACT

BACKGROUND: Online pharmacies have grown significantly in recent years, from US $29.35 billion in 2014 to an expected US $128 billion in 2023 worldwide. Although legitimate online pharmacies (LOPs) provide a channel of convenience and potentially lower costs for patients, illicit online pharmacies (IOPs) open the doors to unfettered access to prescription drugs, controlled substances (eg, opioids), and potentially counterfeits, posing a dramatic risk to the drug supply chain and the health of the patient. Unfortunately, we know little about IOPs, and even identifying and monitoring IOPs is challenging because of the large number of online pharmacies (at least 30,000-35,000) and the dynamic nature of the online channel (online pharmacies open and shut down easily). OBJECTIVE: This study aims to increase our understanding of IOPs through web data traffic analysis and propose a novel framework using referral links to predict and identify IOPs, the first step in fighting IOPs. METHODS: We first collected web traffic and engagement data to study and compare how consumers access and engage with LOPs and IOPs. We then proposed a simple but novel framework for predicting the status of online pharmacies (legitimate or illicit) through the referral links between websites. Under this framework, we developed 2 prediction models, the reference rating prediction method (RRPM) and the reference-based K-nearest neighbor. RESULTS: We found that direct (typing URL), search, and referral are the 3 major traffic sources, representing more than 95% traffic to both LOPs and IOPs. It is alarming to see that direct represents the second-highest traffic source (34.32%) to IOPs. When tested on a data set with 763 online pharmacies, both RRPM and R2NN performed well, achieving an accuracy above 95% in their predictions of the status for the online pharmacies. R2NN outperformed RRPM in full performance metrics (accuracy, kappa, specificity, and sensitivity). On implementing the 2 models on Google search results for popular drugs (Xanax [alprazolam], OxyContin, and opioids), they produced an error rate of only 7.96% (R2NN) and 6.20% (RRPM). CONCLUSIONS: Our prediction models use what we know (referral links) to tackle the many unknown aspects of IOPs. They have many potential applications for patients, search engines, social media, payment companies, policy makers or government agencies, and drug manufacturers to help fight IOPs. With scarce work in this area, we hope to help address the current opioid crisis from this perspective and inspire future research in the critical area of drug safety.

ABSTRACT

BACKGROUND: In recent years, online pharmacies have been accepted by increasingly more consumers, and the prospects for online pharmacies are optimistic. This article explores the consumers' satisfaction factors addressed in Business to Customer (B2C) online pharmacy reviews and analyzes the sentiments expressed in the reviews. The goal of this work is to help B2C online pharmacy enterprises identify consumers' concerns, continuously improve the health services level. METHODS: This article was based on the Latent Dirichlet Allocation (LDA) topic model. From a third-party platform-based B2C online pharmacy and a proprietary B2C online pharmacy (JD Pharmacy and J1.COM, respectively), 136,630 pieces of over-the-counter (OTC) drug review data posted from January 1, 2015 to December 31, 2018 were selected as samples and used to explore the satisfaction factors of B2C online pharmacy consumers regarding the entire drug purchasing process. Then, the sentiments expressed in the drug reviews were analyzed with SnowNLP. RESULT: Categorization of the 12 factors identified by LDA showed that 5 factors were related to logistics; these 5 factors, which also included the most drug reviews, made up 38.5% of the reviews. The number of factors related to drug prices was second, with 3 factors, and reviews of drug prices made up 25.5% of the reviews. Customer service and drug effects each had two related factors, and a smaller percentage of these reviews (13.95%) were related to drug effects. Consumers still maintain positive opinions of JD Pharmacy and J1.COM. However, some opinions on logistics and drug prices are expressed. CONCLUSION: The most important task for online pharmacies is to improve logistics. It is better to develop self-built logistics. Both types of B2C online pharmacies can improve consumer viscosity by implementing marketing strategies. With regard to customer service, focusing on improving employees' service attitudes is necessary.

ABSTRACT

Emergency contraceptive (EC) pills may be less effective for women with higher body mass index (BMI), but little is known about public response to the fact that EC may lose efficacy as weight increases. In November 2013, European authorities changed the label for a levonorgestrel EC product to warn of a reduction in effectiveness for women with higher BMI, garnering significant media coverage in the United States. Ulipristal acetate (UPA) EC may be more effective than levonorgestrel for women with BMI levels designated as obese. Among 8,019 women who received UPA from the online pharmacy KwikMed from 2011 to 2015 and self-reported their height, weight and reasons for seeking UPA online, we analyzed changes in the proportion of women in different BMI categories before and after the label change. For the 25 month-period after the label change, the proportion of women in the obese category rose by 26.7 percentage points relative to the 35 months before (B = 0.2665, p < .01). Mean BMI (25.5 versus 29.4, p < .001) and average weight (148.6 pounds versus 175.5 pounds, p < .001) of users were higher after the label change. Some women appear to have acted on the information that EC efficacy may be associated with body weight.

ABSTRACT

Online coupon retailers and pharmacies are popular sites that patients can access discounted medications when compared to cash prices. These sources are especially important for those patients without insurance. In our study, we analyzed commonly prescribed topical and oral medications and compared the cash prices to the discounted medications based on a typical month of usage. We found savings in every one of the medications that we analyzed, some with savings up to hundreds of dollars. Savings were present in all the sources analyzed, with the coupon-based programs often having the lowest price. We suggest certain alternative prescribing guidelines when considering patients who may not be able to afford cash prices of medications. Our hopes with this study are to quantify savings for discounted medications as well as to help physicians target more affordable medications for their patients.

ABSTRACT

OBJECTIVES: The objective of this study was to evaluate the pharmacy adoption rates of an online Risk Evaluation and Mitigation Strategy (REMS) Pharmacy Portal designed as an alternative for REMS-certified pharmacies to perform mandatory pharmacy dispense confirmations and to assess whether Pharmacy Portal uptake was affected by the pharmacy daily dispense volume. SETTING: REMS-certified pharmacies dispensing lenalidomide (Revlimid), pomalidomide (Pomalyst), or thalidomide (Thalomid). PRACTICE DESCRIPTION: Primarily specialty and hospital pharmacies in the limited distribution network that used the REMS Pharmacy Portal. PRACTICE INNOVATION: A self-service pharmacy portal was developed to allow REMS-certified pharmacies to obtain confirmation numbers instead of calling a Celgene Customer Care Representative (CCR) or using the Interactive Voice Response System (IVR) system. EVALUATION: The numbers of pharmacy dispense confirmations obtained were identified, and the mean percentages by quarter (Q) were calculated from January 2013 through August 2016 for the Pharmacy Portal, Celgene CCR, and IVR. RESULTS: In Q1 2013, the CCR and IVR options were used for 57% and 43% of dispense confirmations, respectively. After the training period, the Pharmacy Portal rapidly became the most used option (67% of confirmations from Q2 2014). By August 2016, data displayed the continued preference for the pharmacy portal (98% of all confirmations) regardless of the daily dispense volume of the pharmacy. As of March 30, 2018, the pharmacy portal continued to be the preferred option for all pharmacies (maintained at 98.5% use). CONCLUSION: There is an overwhelming REMS pharmacy preference to use the pharmacy portal over the IVR and CCR options, irrespective of the pharmacy daily dispense volume. The rapid uptake of the pharmacy portal is most likely attributed to robust and comprehensive 1-on-1 training and support provided by the REMS sponsor to the REMS-certified pharmacies, but also because it might be easier to use than the other options, resulting in reduced REMS burden for the pharmacy.

ABSTRACT

Background and Objectives: The term "telepharmacy" indicates a form of pharmaceutical care in which pharmacists and patients are not in the same place and can interact using information and communication technology (ICT) facilities. Telepharmacy has been adopted to provide pharmaceutical services to underserved areas and to address the problem of pharmacist shortage. This paper has reviewed the multi-faceted phenomenon of telepharmacy, summarizing different experiences in the area. Advantages and limitations of telepharmacy are discussed as well. Materials and Methods: A literature analysis was carried out on PubMed, using as entry term "telepharmacy" and including articles on the topic published between 2012 and 2018. Results: The studies reviewed were divided into three categories of pharmacy practice, namely (1) support to clinical services, (2) remote education and handling of "special pharmacies", and (3) prescription and reconciliation of drug therapies. In general, different telepharmacy services were effective and accompanied by a satisfaction of their targets. Conclusions: Nowadays, the shortage of health personnel, and in particular pharmacists, is a challenging issue that the health systems have to face. The use of a new technology such as telepharmacy can represent a possible option to solve these problems. However, there are unsolved limitations (e.g., legal implications) that make greater diffusion of telepharmacy difficult. Stronger data on the effectiveness of this area of pharmacy care, together with a critical evaluation of its limits, can make actors involved aware about the potentialities of it and could contribute to a larger diffusion of telepharmacy services in the interest of communities and citizens.

ABSTRACT

OBJECTIVE: To evaluate the quality of omeprazole personally imported into Japan via the Internet and to compare the quality of these samples with previously collected samples from two other Asian countries. METHODS: The samples were evaluated by observation, authenticity investigation and pharmacopoeial quality analysis. Quality comparison of some selected samples was carried out by dissolution profiling, Raman spectroscopy and principle component analysis (PCA). RESULTS: Observation of the Internet sites and samples revealed some discrepancies including the delivery of a wrong sample and the selling of omeprazole without a prescription, although it is a prescription medicine. Among the 28 samples analysed, all passed the identification test, 26 (93%) passed the quantity and content uniformity tests and all passed the dissolution test. Dissolution profiling confirmed that all the personally imported omeprazole samples remained intact in the acid medium. On the other hand, six samples from two of the same manufacturers, previously collected during surveys in Cambodia and Myanmar, frequently showed premature omeprazole release in acid. Raman spectroscopy and PCA showed significant variation between omeprazole formulations in personally imported samples and the samples from Cambodia and Myanmar. CONCLUSIONS: Our results indicate that the pharmaceutical quality of omeprazole purchased through the Internet was sufficient, as determined by pharmacopeial tests. However, omeprazole formulations distributed in different market segments by the same manufacturers were of diverse quality. Measures are needed to ensure consistent quality of products and to prevent entry of substandard products into the legitimate supply chain.

ABSTRACT

PURPOSE: Gamma-hydroxybutyrate (GHB) withdrawal is a life-threatening condition that does not always respond to standard treatment with benzodiazepines. Baclofen has potential utility as a pharmacological adjunct and anecdotal reports suggest that it is being used by drug users to self-manage GHB withdrawal symptoms. Here, we investigate current patterns of use and the online availably of baclofen. METHODS: Data triangulation techniques were applied to published scientific literature and publicly accessible Internet resources (grey literature) to assess the use of baclofen in GHB withdrawal. An Internet snapshot survey was performed to identify the availability of baclofen for online purchase and the compliance of retailers with the UK regulations. Data were collected according to pre-defined criteria. RESULTS: A total of 37 cases of baclofen use in GHB withdrawal were identified in the scientific literature, as well as 51 relevant discussion threads across eight Internet forums in the grey literature. Baclofen was available to purchase from 38 online pharmacies, of which only one conformed to the UK regulations. CONCLUSIONS: There is limited published evidence on the use of baclofen in GHB withdrawal, but both scientific and grey literature suggests clinical utility. Online pharmacies are readily offering prescription-only-medication without prescription and due to inadequate regulation, pose a danger to the public.

ABSTRACT

BACKGROUND: During the past two decades, the internet has become an accepted way to purchase products and services. Buying medications online are no exception. Besides its benefits, several patient safety risks are linked to the purchase of medicines outside the traditional supply chain. Although thousands of internet pharmacies are accessible on the web, the actual size of the market is unknown. Currently, there is limited data available on the use of internet pharmacies, the number, and attitude of people obtaining medications and other health products from the internet. OBJECTIVE: This study aims to gather information on the frequency and attitudes of patients purchasing medications online in a nationally representative sample of outpatients. Attitudes towards main supply chain channels, perceived benefits, and disadvantages of influencing online medication purchase are evaluated. METHODS: A cross-sectional explorative study using a personally administered survey was conducted in a representative sample of Hungarian outpatients in 2018. RESULTS: A total of 1055 outpatients completed the survey (response rate 77.23%). The mean age was 45 years, and 456 (43.22%) reported having chronic health conditions. The majority (872/1055, 82.65%) of the respondents were aware that medications could be obtained online, but only 44 (4.17%) used the internet for previous medication purchases. Attitudes towards the different pharmaceutical supply chain retail channels showed significant differences (P<.001), respondents accepted retail pharmacy units as the most appropriate source of medications while rejected internet pharmacies. Respondents were asked to evaluate 9 statements regarding the potential benefits and disadvantages about the online medicine purchase, and based on the computed relative attitude rate there is a weak still significant tendency toward rejection (P<.001). Correspondence of demographic factors, internet usage behavior, and prospective online drug purchase attitude was evaluated. Respondents who use the internet more and purchase goods online will be more likely to buy medications online. Furthermore, youth and education will determine the medication purchase behavior. CONCLUSIONS: Many patients will purchase medications on the internet in the future. Currently, there is an increased risk of patients buying products from illegal sites because these dominate the global online pharmacy market. Consequently, improved patient-provider communication and promotion campaigns are needed to inform the public about the safe use of internet pharmacies, as these initiatives can directly prevent patient safety threats.

ABSTRACT

BACKGROUND: On December 6 and 7, 2017, the US Department of Health and Human Services (HHS) hosted its first Code-a-Thon event aimed at leveraging technology and data-driven solutions to help combat the opioid epidemic. The authors­an interdisciplinary team from academia, the private sector, and the US Centers for Disease Control and Prevention­participated in the Code-a-Thon as part of the prevention track. OBJECTIVE: The aim of this study was to develop and deploy a methodology using machine learning to accurately detect the marketing and sale of opioids by illicit online sellers via Twitter as part of participation at the HHS Opioid Code-a-Thon event. METHODS: Tweets were collected from the Twitter public application programming interface stream filtered for common prescription opioid keywords in conjunction with participation in the Code-a-Thon from November 15, 2017 to December 5, 2017. An unsupervised machine learning­based approach was developed and used during the Code-a-Thon competition (24 hours) to obtain a summary of the content of the tweets to isolate those clusters associated with illegal online marketing and sale using a biterm topic model (BTM). After isolating relevant tweets, hyperlinks associated with these tweets were reviewed to assess the characteristics of illegal online sellers. RESULTS: We collected and analyzed 213,041 tweets over the course of the Code-a-Thon containing keywords codeine, percocet, vicodin, oxycontin, oxycodone, fentanyl, and hydrocodone. Using BTM, 0.32% (692/213,041) tweets were identified as being associated with illegal online marketing and sale of prescription opioids. After removing duplicates and dead links, we identified 34 unique "live" tweets, with 44% (15/34) directing consumers to illicit online pharmacies, 32% (11/34) linked to individual drug sellers, and 21% (7/34) used by marketing affiliates. In addition to offering the "no prescription" sale of opioids, many of these vendors also sold other controlled substances and illicit drugs. CONCLUSIONS: The results of this study are in line with prior studies that have identified social media platforms, including Twitter, as a potential conduit for supply and sale of illicit opioids. To translate these results into action, authors also developed a prototype wireframe for the purposes of detecting, classifying, and reporting illicit online pharmacy tweets selling controlled substances illegally to the US Food and Drug Administration and the US Drug Enforcement Agency. Further development of solutions based on these methods has the potential to proactively alert regulators and law enforcement agencies of illegal opioid sales, while also making the online environment safer for the public.

ABSTRACT

Background: Improved antibiotic stewardship (AS) and reduced prescribing in primary care, with a parallel increase in personal internet use, could lead citizens to obtain antibiotics from alternative sources online. Objectives: A cross-sectional analysis was performed to: (i) determine the quality and legality of online pharmacies selling antibiotics to the UK public; (ii) describe processes for obtaining antibiotics online from within the UK; and (iii) identify resulting AS and patient safety issues. Methods: Searches were conducted for 'buy antibiotics online' using Google and Yahoo. For each search engine, data from the first 10 web sites with unique URL addresses were reviewed. Analysis was conducted on evidence of appropriate pharmacy registration, prescription requirement, whether antibiotic choice was 'prescriber-driven' or 'consumer-driven', and whether specific information was required (allergies, comorbidities, pregnancy) or given (adverse effects) prior to purchase. Results: Twenty unique URL addresses were analysed in detail. Online pharmacies evidencing their location in the UK ( n = 5; 25%) required a prescription before antibiotic purchase, and were appropriately registered. Online pharmacies unclear about the location they were operating from ( n = 10; 50%) had variable prescription requirements, and no evidence of appropriate registration. Nine (45%) online pharmacies did not require a prescription prior to purchase. For 16 (80%) online pharmacies, decisions were initially consumer-driven for antibiotic choice, dose and quantity. Conclusions: Wide variation exists among online pharmacies in relation to antibiotic practices, highlighting considerable patient safety and AS issues. Improved education, legislation, regulation and new best practice stewardship guidelines are urgently needed for online antibiotic suppliers.

ABSTRACT

OBJECTIVES: To deploy a methodology accurately identifying tweets marketing the illegal online sale of controlled substances. METHODS: We first collected tweets from the Twitter public application program interface stream filtered for prescription opioid keywords. We then used unsupervised machine learning (specifically, topic modeling) to identify topics associated with illegal online marketing and sales. Finally, we conducted Web forensic analyses to characterize different types of online vendors. We analyzed 619 937 tweets containing the keywords codeine, Percocet, fentanyl, Vicodin, Oxycontin, oxycodone, and hydrocodone over a 5-month period from June to November 2015. RESULTS: A total of 1778 tweets (< 1%) were identified as marketing the sale of controlled substances online; 90% had imbedded hyperlinks, but only 46 were "live" at the time of the evaluation. Seven distinct URLs linked to Web sites marketing or illegally selling controlled substances online. CONCLUSIONS: Our methodology can identify illegal online sale of prescription opioids from large volumes of tweets. Our results indicate that controlled substances are trafficked online via different strategies and vendors. Public Health Implications. Our methodology can be used to identify illegal online sellers in criminal violation of the Ryan Haight Online Pharmacy Consumer Protection Act.

ABSTRACT

BACKGROUND: The rising prevalence of chronic diseases is pressing health systems to introduce reforms. Primary healthcare and multidisciplinary models have been suggested as approaches to deal with this challenge, with new roles for nurses and pharmacists being advocated. More recently, implementing healthcare based on information systems and technologies (e.g. eHealth) has been proposed as a way to improve health services. However, implementing online pharmaceutical services, including their adoption by pharmacists and patients, is still an open research question. In this paper we present ePharmacare, a new online pharmaceutical service implemented using Design Science Research. METHODS: The Design Science Research Methodology (DSRM) was chosen to implement this online service for chronic diseases management. In the paper, DSRM's different activities are explained, from the definition of the problem to the evaluation of the artifact. During the design and development activities, surveys, observations, focus groups, and eye-tracking glasses were used to validate pharmacists' and patients' requirements. During the demonstration and evaluation activities the new service was used with real-world pharmacists and patients. RESULTS: The results show the contribution of DSRM in the implementation of online services for pharmacies. We found that pharmacists spend only 50% of their time interacting with patients, uncovering a clear opportunity to implement online pharmaceutical care services. On the other hand, patients that regularly visit the same pharmacy recognize the value in patient follow-up demanding to use channels such as the Internet for their pharmacy interactions. Limitations were identified regarding the high workload of pharmacists, but particularly their lack of know-how and experience in dealing with information systems (IST) for the provision of pharmaceutical services. CONCLUSIONS: This paper summarizes a research project in which an online pharmaceutical service was proposed, designed, developed, demonstrated and evaluated using DSRM. The main barriers for pharmacists' adoption of online pharmaceutical services provision were the lack of time, time management and information systems usage skills, as well as a precise role definition within pharmacies. These problems can be addressed with proper training and services reorganization, two proposals to be investigated in future works.

ABSTRACT

Background: The intensive use of Internet as health guide is proved by a current representative survey. Online orders of OTC pharmaceuticals and prescription medicine represent a special way of utillisation. Intention: The aim of the following study is to investigate motives and backgrounds of self-medication in coherency of health and ordering of OTC pharmaceuticals via Internet. Method: With an online questionnaire developed in particular for this thesis N=104 internet users (mean age M=32,7; SD=11,1 consisting of 73 female and 31 male participants) were questioned concerning the relevant topics. Furthermore, the subjects were interviewed with regard to identification of their quality of life (with the German version of the EUROHIS-QOL 8 item index), their well-being (by using the German version of the WHO-5 well-being index, version II). Results: The wish for (especially temporal) independence from a physicians treatment and the idea of a faster convalescence or prevention of worse ailment could be identified as motives for self-medication. The most frequently selected advantages of ordering drugs via internet were the lower price, organisational aspects such as direct home delivery or saving time without a consultation. In contrast, the lack of advice was often mentioned as a possible disadvantage, just like the risk of undetected and undiagnosed diseases. Compared to participants who did not do any Internet orders, participants who ordered their non-prescription drugs on the Internet were less aware of possible risks and they also used painkillers available without prescription more frequently. However, there were no differences in the total amount of applied OTC medications, which made a drug abuse less likely. Overall, self-medication of the users of Internet forums interviewed within this thesis seemed to be quantitatively and qualitatively appropriate. Conclusion: Self-medication by Internet users in this study seems to be reasonable in a quantitative and qualitative way.
