Background Xpert HCV Viral Load Fingerstick assay (Xpert HCV VL FS) is a point-of-care test quantifying HCV RNA in Methods This study evaluated time to HCV RNA detection using the Xpert HCV VL FS assay. Fingerstick whole-blood samples were collected from participants in an observational cohort in Australia. Results In May 2018–2019, 1468 participants were enrolled, 1426 had Xpert HCV VL FS testing performed, and 1386 had a valid result. HCV RNA was detected in 23% (325/1386). Among people with undetectable HCV RNA (n = 1061), median time to result was 57 minutes. Among people with detectable HCV RNA (n = 325), median time to HCV RNA detection was 32 minutes and 80% (261/325) had a detectable HCV RNA result in ≤40 minutes. Median time to HCV RNA detection was dependent on HCV RNA level. Conclusions A quicker HCV diagnosis could be achieved by monitoring the time when HCV RNA is first detected with the Xpert HCV VL FS test, rather than HCV RNA quantification, although the current platform does not allow for this. These findings could facilitate new strategies to reduce waiting times for an HCV diagnosis and improve linkage to treatment.

Awareness of hepatitis C virus (HCV) infection status among people who inject drugs (PWID) can empower people with diagnosis, enable treatment uptake, and facilitate elimination. We aimed to evaluate awareness of HCV infection status among a large national cohort of PWID in an era of unrestricted HCV treatment.ETHOS Engage is an observational cohort study of PWID attending drug treatment clinics and needle and syringe programs in Australia. Participants completed a questionnaire containing self-reported HCV data (including infection status: never tested, tested/unknown, no current HCV infection [HCV RNA not detectable], current HCV infection [HCV RNA detectable]) and underwent point-of-care HCV RNA testing (Xpert® HCV Viral Load Fingerstick). Awareness was defined as concordant self-reported HCV status and test result. Awareness was assessed among all participants, those with current HCV infection, and participants who reported a lifetime history of HCV treatment. Logistic regression was used to assess factors associated with awareness in these three populations.Among 2,305 PWID, 65% (n=1,506) were aware of their HCV infection status (self-reported HCV status matched HCV point-of-care result). Awareness of infection status was higher among those who were not currently infected (70%, n=1,281/1,818) compared to those with current HCV infection (46%, n=225/487). After adjusting, those with current HCV infection were less likely to be aware of infection status (aOR: 0.40, 95%CI: 0.30, 0.45). Among those who reported a lifetime history of HCV treatment, 71% (n=592/829) were aware of their HCV infection status.Among a large cohort of PWID in Australia, awareness of HCV infection status is sub-optimal, with particularly concerning levels among those with active infection. Increased and simplified testing, post-test counselling, and post-treatment monitoring is warranted.

Evidence regarding the acceptability of contingency management is limited. We investigated the willingness of people who inject drugs to participate in a randomised controlled trial (RCT) involving financial incentives to initiate HCV treatment.ETHOS Engage is an observational cohort study of people with a history of injecting drug use who either injected in the past six months or receive opioid agonist therapy (OAT) in Australia. We assessed willingness to participate in a RCT with financial incentives and factors associated with preference for entire incentive ($60) at first clinic visit versus delayed incentive with logistic regression.93% (593/635) of eligible participants agreed to participate in an RCT with financial incentives of which 24% were Aboriginal or Torres Strait Islander, 84% had completed secondary school, and 59% injected drugs in the prior month. Willingness to participate in an RCT increased by amount offered: unspecified (72%), $20 (75%), $60 (80%), and $100 (85%). The preferred incentive distribution method over three clinical visits was entire incentive at first clinical visit (32%). Among those with a preferred distribution method (n = 369), factors associated with entire incentive at first clinic visit were being Aboriginal or Torres Strait Islander (aOR 1.75; 95% CI 1.05-2.94), completion of secondary school (aOR 0.46; 95% CI 0.26-0.83) and mainly injected heroin in month prior (aOR 1.82; 95% CI 1.03-3.20).Most participants were willing to participate in an RCT involving financial incentives to initiate treatment but differed regarding distribution. Study findings inform implementation of incentives in clinical practice.

Injecting-related skin and soft tissue infections (SSTIs) are a preventable cause of inpatient hospitalisation among people who inject drugs (PWID). This study aimed to determine the prevalence of hospitalisation for SSTIs among PWID, and identify similarities and differences in factors associated with hospitalisation for SSTIs versus non-bacterial harms related to injecting drug use.We performed cross-sectional analyses of baseline data from an observational cohort study of PWID attending drug treatment clinics and needle and syringe programs in Australia. Logistic regression models were used to identify factors associated with self-reported hospitalisation for (1) SSTIs (abscess and/or cellulitis), and (2) non-bacterial harms related to injecting drug use (e.g., non-fatal overdose; hereafter referred to as non-bacterial harms), both together and separately.1851 participants who injected drugs in the previous six months were enrolled (67% male; 85% injected in the past month; 42% receiving opioid agonist treatment [OAT]). In the previous year, 40% (n = 737) had been hospitalised for drug-related causes: 20% (n = 377) and 29% (n = 528) of participants were admitted to hospital for an SSTI and non-bacterial harm, respectively. Participants who were female (adjusted odds ratio [aOR]: 1.53, 95% CI: 1.19-1.97) or homeless (aOR: 1.59, 95% CI: 1.16-2.19) were more likely to be hospitalised for an SSTI, but not a non-bacterial harm. Both types of hospitalisation were more likely among people recently released from prison.Hospitalisation for SSTIs is common among PWID. Community-based interventions to prevent SSTIs and subsequent hospitalisation among PWID will require targeting of at-risk groups, including women, people experiencing homelessness, and incarcerated people upon prison release.

Background Overdose is a major cause of morbidity and mortality among people who use opioids. Naloxone can reverse opioid overdoses and can be distributed and administered with minimal training. People with experience of overdose are a key population to target for overdose prevention strategies. This study aims to understand if factors associated with recent non-fatal opioid overdose are the same as factors associated with naloxone access and naloxone training in people who recently used opioids or received opioid agonist treatment (OAT). Methods ETHOS Engage is an observational study of people who inject drugs in Australia. Logistic regression models were used to estimate odds ratios for non-fatal opioid overdose, naloxone access and naloxone training. Results Between May 2018-September 2019, 1280 participants who recently used opioids or received OAT were enrolled (62% aged >40 years; 35% female, 80% receiving OAT, 62% injected drugs in the preceding month). Recent opioid overdose (preceding 12 months) was reported by 7% of participants, lifetime naloxone access by 17%, and lifetime naloxone training by 14%. Compared to people receiving OAT with no additional opioid use, recent opioid, benzodiazepine (preceding six months), and hazardous alcohol use was associated with recent opioid overdose (aOR 3.91; 95%CI: 1.68–9.10) and lifetime naloxone access (aOR 2.12; 95%CI 1.29–3.48). Among 91 people who reported recent overdose, 65% had never received take-home naloxone or naloxone training. Conclusions Among people recently using opioids or receiving OAT, benzodiazepine and hazardous alcohol use is associated with non-fatal opioid overdose. Not all factors associated with non-fatal overdose correspond to factors associated with naloxone access. Naloxone access and training is low across all groups. Additional interventions are needed to scale up naloxone provision.

Background Evaluating progress towards hepatitis C virus (HCV) elimination is critical. This study estimated prevalence of current HCV infection and HCV treatment uptake among people who inject drugs (PWID) in Australia. Methods The Enhancing Treatment of Hepatitis C in Opioid Substitution Settings Engage is an observational study of PWID attending drug treatment clinics and needle and syringe programs (NSPs). Participants completed a questionnaire including self-reported treatment history and underwent point-of-care HCV RNA testing (Xpert HCV Viral Load Fingerstick; Cepheid). Results Between May 2018 and September 2019, 1443 participants were enrolled (64% injected drugs in the last month, 74% receiving opioid agonist therapy [OAT]). HCV infection status was uninfected (28%), spontaneous clearance (16%), treatment-induced clearance (32%), and current infection (24%). Current HCV was more likely among people who were homeless (adjusted odds ratio, 1.47; 95% confidence interval, 1.00–2.16), incarcerated in the previous year (2.04; 1.38–3.02), and those injecting drugs daily or more (2.26; 1.43–2.42). Among those with previous chronic or current HCV, 66% (n = 520/788) reported HCV treatment. In adjusted analysis, HCV treatment was lower among females (.68; .48–.95), participants who were homeless (.59; .38–.96), and those injecting daily or more (.51; .31–.89). People aged ≥45 years (1.46; 1.06–2.01) and people receiving OAT (2.62; 1.52–4.51) were more likely to report HCV treatment. Conclusions Unrestricted direct-acting antiviral therapy access in Australia has yielded high treatment uptake among PWID attending drug treatment and NSPs, with a marked decline in HCV prevalence. To achieve elimination, PWID with greater marginalization may require additional support and tailored strategies to enhance treatment.

Background. Alternative combination antiretroviral therapies in virologically suppressed human immunodeficiency virus (HIV)-infected patients experiencing side effects and/or at ongoing risk of important comorbidities from current therapy are needed. Maraviroc (MVC), a chemokine receptor 5 antagonist, is a potential alternative component of therapy in those with R5-tropic virus. Methods. The Maraviroc Switch Study is a randomized, multicenter, 96-week, open-label switch study in HIV type 1-infected adults with R5-tropic virus, virologically suppressed on a ritonavir-boosted protease inhibitor (PI/r) plus double nucleoside/nucleotide reverse transcriptase inhibitor (2 N(t)RTI) backbone. Participants were randomized 1:2:2 to current combination antiretroviral therapy (control), or replacing the protease inhibitor (MVC + 2 N(t)RTI arm) or the nucleoside reverse transcriptase inhibitor backbone (MVC + PI/r arm) with twice-daily MVC. The primary endpoint was the difference (switch minus control) in proportion with plasma viral load (VL)

The Medicare Part D benefit expands the universe of cancer drugs and biologics that Medicare may cover. Individual Part D plans have discretion to determine their formularies and cost sharing for drugs within federal guidelines. This paper analyzes differences in coverage and cost sharing for cancer drugs among these plans. We find that many cancer drugs, including brand-name products, are covered by almost all plans, although prior authorization might limit access to some. In addition, many plans charge a relatively low copayment for most cancer drugs. These findings suggest that Part D could greatly expand beneficiaries' access to cancer treatments.

This chapter considers business communication from a different perspective, as a transaction within the total business information system rather than as one step in solving a management problem. The first section invites you to consider your own information system, the way you collect, store, process and communicate information to carry out your job. Another section looks at the role of IT in the wider business enterprise, and the final section looks at some of the likely trends for the future.

We have reviewed and discussed data concerning the development of hepatobiliary dysfunction in the patient requiring TPN. The data above can be summarised in a short statement--TPN-related hepatobiliary dysfunction is multifactorial. Despite all the factors discussed, the patients underlying disease state and the severity of the illness may be the most significant factor in the development of hepatobiliary dysfunction. With our current state of knowledge it is only possible for the clinician to be aware which of his patients are most likely to develop problems, and to forecast the type of dysfunction that is most likely to occur. There is no treatment--apart from stopping TPN--but there are certain methods by which the incidence and degree of dysfunction may be minimised, or some of the complications (e.g. gallstones) treated. Fortunately in most cases the degree of dysfunction is both self-limiting and reversible on cessation of TPN.

Enteral nutrition is only part of the wider field of clinical nutrition in which great advances in both theory and practice have been made over the last decade. We have attempted to summarize what we consider to be the advances that have most relevance to the clinical practice of enteral nutrition. This chapter reviews our present understanding of the processes of digestion and absorption of protein, carbohydrate and fats, and examines how this theoretical understanding can be applied to patients in the clinical situation. A broad classification of the different enteral diets is undertaken, and the reasons for the development of particular diets are discussed. The clinical value of these diets is assessed. The wide variety of indications for enteral (as opposed to parenteral) nutrition are discussed and the specific benefits of enteral nutrition for the patient are highlighted. Techniques of administration of enteral nutrition are reviewed in detail, and the methods by which enteral nutrition should be monitored are outlined. Finally, complications of enteral nutrition are summarized and advice given on how to prevent or treat them.
