RESUMO

INTRODUCTION: Current antiretroviral therapies (ARTs) have improved outcomes for people living with HIV. However, the requirement to adhere to lifelong daily oral dosing may be challenging for some people living with HIV, leading to suboptimal adherence and therefore reduced treatment effectiveness. Treatment with long-acting (LA) ART may improve adherence and health-related quality of life. The objective of this study was to evaluate the cost-effectiveness of cabotegravir + rilpivirine (CAB+RPV) LA administered every 2 months (Q2M) compared with current ART administered as daily oral single-tablet regimens (STRs) from a Spanish National Healthcare System perspective. METHODS: A hybrid decision-tree and Markov state-transition model was used with pooled data from three phase III/IIIb trials (FLAIR, ATLAS, and ATLAS-2M) over a lifetime horizon, with health states defined by viral load and CD4+ cell count. Direct costs (in €) were taken from Spanish public sources from 2021 and several deterministic and probabilistic analyses were carried out. An annual 3% discount rate was applied to both costs and utilities. RESULTS: Over the lifetime horizon, CAB+RPV LA Q2M was associated with an additional 0.27 quality-adjusted life years (QALYs) and slightly greater lifetime costs (€4003) versus daily oral ART, leading to an incremental cost-effectiveness ratio of €15,003/QALY, below the commonly accepted €30,000/QALY willingness-to-pay threshold in Spain. All scenario analyses showed consistent results, and the probabilistic sensitivity analysis showed cost-effectiveness compared with daily oral STRs in 62.4% of simulations, being dominant in 0.3%. CONCLUSION: From the Spanish National Health System perspective, CAB+RPV LA Q2M is a cost-effective alternative compared with the current options of daily oral STR regimens for HIV treatment. CLINICAL TRIALS REGISTRATION: ATLAS, NCT02951052; ATLAS-2M, NCT03299049; FLAIR, NCT02938520.


Over the past decades, treatments for HIV infection have improved outcomes for people living with HIV. However, most of the treatments available consist of daily oral administration, which may present challenges for some people. These challenges may lead to a less optimal intake of the medicines and, therefore, to a potential reduction of treatment effectiveness. A new long-acting treatment alternative for HIV with two drugs is now available: cabotegravir + rilpivirine long-acting is the first injectable treatment administered in the muscle every 2 months by a healthcare professional. Long-acting injectables may improve treatment administration and health-related quality of life of people living with HIV. This study estimated the cost-effectiveness of cabotegravir + rilpivirine long-acting in Spain compared with daily oral single-tablet treatment for HIV. An economic model using clinical data and Spanish inputs was used to estimate cost-effectiveness and health outcomes over a lifetime. Cabotegravir + rilpivirine long-acting compared with daily oral single-tablet treatment showed an increase in health-related quality of life, leading to a cost-effectiveness ratio of €15,003, below the Spanish willingness-to-pay threshold of €30,000. All different scenarios tested showed consistent results, with cabotegravir + rilpivirine long-acting being cost-effective in 62.4% of the simulations and less costly and more effective in 0.3%. This study demonstrated that, in Spain, cabotegravir + rilpivirine long-acting administered every 2 months is a cost-effective alternative to the current daily oral single-tablet treatment options for HIV.

RESUMO

INTRODUCTION: HIV continues to represent a problem of great relevance for public health in Spain. This study aims to carry out an analysis that will provide in-depth knowledge of the resources, clinical care, and management during the diagnosis, follow-up, and treatment phases of HIV infection in Spain. METHODS: In the first phase, a multidisciplinary Scientific Committee designed an information collection tool in the form of a survey. In the second phase, carried out in the autonomous communities of Andalusia, Catalonia, and La Rioja, a multidisciplinary group of 42 experts, representatives of the public administration, clinical profiles, and representatives of NGOs in the field of HIV answered the survey. RESULTS: The assessment of HIV resources is generally positive. As regards diagnosis, the experts considered that there was good coordination between Primary and Hospital care. Regarding treatment, the evaluations reflected good opinions on therapeutic conciliation and adherence, with a negative opinion in the evaluation of drug interactions with antiretroviral treatment. Regarding follow-up, the perception expressed was disparate concerning the coordination between Hospital and Primary Care as well as the adaptation of care to chronicity, aging, fragility, mental health, and oncological processes. CONCLUSION: There are certain processes that can be improved in the management of HIV infection in people with HIV in Spain, including protocols for follow-up and coordination between primary and hospital care in the treatment and follow-up of the disease.

RESUMO

INTRODUCTION: The majority of cancer patients report malnutrition, with a significant impact on patient's outcome. This study aimed to compare how nutritional assessment is conducted across different surgical oncology sub-specialties. METHODS: Survey modules were designed for breast, hepato-pancreato-biliary (HPB), upper-gastrointestinal (UGI), sarcoma, peritoneal and surface malignancies (PSM) and colorectal cancer (CRC) surgeries to describe 4 domains: participants' setting, evaluation of clinical factors, use of screening tools and clinical practice. Results were compared among sub-specialties and according to human development index (HDI) in the largest cohorts. RESULTS: Out of 457 answers from 377 global participants (62% European), 35.0% were from breast and 28.9% were from CRC surgeons. Although MDTs management is consistently reported (64-88%), the presence of a nutritionist/dietician ranges from 14.1% to 44.2%. Breast surgeons seldom evaluate albumin (25.6%) and weight loss (30.6%), opposite to HPB, PSM and UGI groups (>70%, p 0.044). Overall, responders declared that the use of screening tools is largely neglected, that nutritional status is often assessed by the surgeons and that nutrition is not consistently modified according to risk factors (range among groups respectively: 1.9%-25.6%, 33.1%-51.4%, 33.1%-60.5%). Less than 20% of breast surgeons assess patients before/after surgery, comparing to >60% of PSM surgeons. However, no statistical differences were documented comparing groups for the majority of the items of the 4 domains. Nutritional evaluation is more often conducted by breast surgeons in medium/low HDI countries comparing very high/high HDI (p 0.04). CONCLUSIONS: Nutritional assessment is largely neglected. These results identify target-issues for the implementation of clinical practice.

RESUMO

BACKGROUND: Two-drug regimens (2DR) to treat HIV infection have the potential to reduce long-term toxicity and increase therapeutic options for people living with HIV (PLHIV). Prior phase III trials, SWORD-1 and SWORD-2, as well as GEMINI-1 and GEMINI-2, have demonstrated that a dolutegravir-based 2DR is as effective as three- or four-drug regimens among virologically suppressed patients. Limited information exists, however, on patient and provider experiences with 2DR to inform roll-out and integration into routine clinical care. METHODS: We conducted 39 in-depth interviews with PLHIV currently on 2DR in the context of routine care and 8 of their clinical care providers in the United States (U.S.) and Spain. Participants included 33 male and 6 female PLHIV and 8 providers. Interview topics explored perceptions of and experiences with 2DR compared to prior anti-retroviral regimens (ARVs), side effects, patient satisfaction, and clinical performance. Interviews were audio-recorded, transcribed and analyzed using thematic content analysis. RESULTS: Participants viewed 2DR as a significant and positive advance, in terms of its ability to effectively treat HIV with reduced toxicity and essentially no reported side effects. Patients noted the central role providers played in the decision to switch to a 2DR regimen and, among U.S. participants, the importance of insurance coverage making this preferred option feasible. Patients and providers agreed that a 2DR regimen would be appropriate for any PLHIV regardless of whether they were treatment naïve or had significant experience with ARVs. CONCLUSIONS: Participants' experiences with a 2DR regimen were positive with no participants, reporting side effects and all reporting continued viral suppression. Providers valued the reduced toxicity offered by 2DR and served as the primary gateway to a transition to 2DR for patients in both settings. This study provides a foundation for further research on the transition to 2DR regimens in other populations and contexts including low- and middle-income settings.

RESUMO

The debate on drug prices has reached new heights with the controversy around the role of prices in promoting innovation. Critics claim that prices of innovative drugs are excessive and argue that lowering prices will not harm the flourishing innovation. On the opposite end, the pharmaceutical industry insists that restrictive pricing policies will have a detrimental impact on their ability to generate innovation. Amid these two divergent positions, this manuscript presents a conceptual framework to better understand the role played by drug prices to influence the ability of pharmaceutical firms to raise money in capital markets and hence finance pharmaceutical innovation. We argue that deviations from established value-based pricing principles, by either firms or payers, will distort access by firms to capital and lead to an undesirable level of innovation in the long term. We hope that this framework helps policy-makers anticipate the impact of their proposals, and ultimately guide policies towards setting optimal drug prices as a means to maximise social welfare.

RESUMO

INTRODUCTION: Our aims were to investigate the adherence to national guidelines of initial antiretroviral therapy (ART) in the Spanish multicenter CoRIS cohort during the years 2010-2015, to identify the reasons for the prescription of nonrecommended treatments, and to explore the role of institutional constraints to guideline compliance. METHODS: ART regimens were classified as recommended, alternative or nonrecommended according to the guidelines. Physicians were asked the reasons for prescribing nonrecommended regimens. Factors associated with the prescription of non recommended regimens were assessed using multivariable logistic regression. RESULTS: During the study period, 586 (10.7%) of 5479 patients who started ART were given a regimen not recommended in the guidelines. The most frequent reasons for prescribing nonrecommended regimens were: enrolment in clinical trials (43.3%), comorbidities and/or interactions (10.2%), pregnancy (8.7%), and cost (7.7%). Among 37 participating centers, 16 (43%), treating 3561 patients, reported limitations related with the cost of ART, and 20 (54%), treating 1365 patients, reported restrictions for prescribing at least one recommended antiretroviral. In multivariable analysis, a higher risk of receiving nonrecommended regimens was associated with male gender, HIV acquisition by heterosexual transmission, low viral loads, initiation of treatment during the years 2011 to 2015, and initiation of treatment in a center with restricted access to at least one antiretroviral drug. CONCLUSIONS: Compliance to clinical guidelines was high. A high proportion of centres reported cost limitations for ART or restricted access to at least one recommended antiretroviral drug, with a significant impact on the choice of initial regimens.

RESUMO

BACKGROUND: The GESIDA/National AIDS Plan expert panel recommended preferred regimens (PR), alternative regimens (AR) and other regimens (OR) for antiretroviral treatment (ART) as initial therapy in HIV-infected patients for 2018. The objective of this study was to evaluate the costs and the efficiency of initiating treatment with PR and AR. METHODS: Economic assessment of costs and efficiency (cost-effectiveness) based on decision tree analyses. Effectiveness was defined as the probability of reporting a viral load <50copies/mL at week 48, in an intention-to-treat analysis. Cost of initiating treatment with an ART regimen was defined as the costs of ART and its consequences (adverse effects, changes of ART regimen, and drug-resistance studies) over the first 48 weeks. The payer perspective (National Health System) was applied considering only differential direct costs: ART (official prices), management of adverse effects, studies of resistance, and HLA B*5701 testing. The setting was Spain and the costs correspond to those of 2018. A deterministic sensitivity analysis was conducted, building three scenarios for each regimen: base case, most favourable and least favourable. RESULTS: In the base-case scenario, the cost of initiating treatment ranges from 6788 euros for TAF/FTC/RPV (AR) to 10,649 euros for TAF/FTC+RAL (PR). The effectiveness varies from 0.82 for TAF/FTC+DRV/r (AR) to 0.91 for TAF/FTC+DTG (PR). The efficiency, in terms of cost-effectiveness, ranges from 7814 to 12,412 euros per responder at 48 weeks, for ABC/3TC/DTG (PR) and TAF/FTC+RAL (PR), respectively. CONCLUSION: Considering ART official prices, the most efficient regimen was ABC/3TC/DTG (PR), followed by TAF/FTC/RPV (AR) and TAF/FTC/EVG/COBI (AR).

RESUMO

INTRODUCTION: GESIDA and the Spanish National AIDS Plan panel of experts have recommended preferred (PR), alternative (AR) and other regimens (OR) for antiretroviral therapy (ART) as initial therapy in HIV-infected patients for 2017. The objective of this study was to evaluate the costs and the efficiency of initiating treatment with PR and AR. METHODS: Economic assessment of costs and efficiency (cost-efficacy) based on decision tree analyses. Efficacy was defined as the probability of reporting a viral load <50copies/mL at week 48, in an intention-to-treat analysis. Cost of initiating treatment with an ART regimen was defined as the costs of ART and its consequences (adverse effects, changes of ART regimen and drug resistance studies) during the first 48 weeks. The payer perspective (National Health System) was applied considering only differential direct costs: ART (official prices), management of adverse effects, resistance studies and HLA B*5701 screening. The setting was Spain and the costs correspond to those of 2017. A deterministic sensitivity analysis was conducted, building three scenarios for each regimen: base case, most favourable and least favourable. RESULTS: In the base case scenario, the cost of initiating treatment ranged from 6882 euro for TFV/FTC/RPV (AR) to 10,904 euros for TFV/FTC+RAL (PR). The efficacy varied from 0.82 for TFV/FTC+DRV/p (AR) to 0.92 for TAF/FTC/EVG/COBI (PR). The efficiency, in terms of cost-efficacy, ranged from 7923 to 12,765 euros per responder at 48 weeks, for ABC/3TC/DTG (PR) and TFV/FTC+RAL (PR), respectively. CONCLUSION: Considering ART official prices, the most efficient regimen was ABC/3TC/DTG (PR), followed by TFV/FTC/RPV (AR) and TAF/FTC/EVG/COBI (PR).

RESUMO

BACKGROUND: Clinical guidelines vary with respect to the optimal monitoring frequency of HIV-positive individuals. We compared dynamic monitoring strategies based on time-varying CD4 cell counts in virologically suppressed HIV-positive individuals. METHODS: In this observational study, we used data from prospective studies of HIV-positive individuals in Europe (France, Greece, the Netherlands, Spain, Switzerland, and the UK) and North and South America (Brazil, Canada, and the USA) in The HIV-CAUSAL Collaboration and The Centers for AIDS Research Network of Integrated Clinical Systems. We compared three monitoring strategies that differ in the threshold used to measure CD4 cell count and HIV RNA viral load every 3-6 months (when below the threshold) or every 9-12 months (when above the threshold). The strategies were defined by the threshold CD4 counts of 200 cells per µL, 350 cells per µL, and 500 cells per µL. Using inverse probability weighting to adjust for baseline and time-varying confounders, we estimated hazard ratios (HRs) of death and of AIDS-defining illness or death, risk ratios of virological failure, and mean differences in CD4 cell count. FINDINGS: 47 635 individuals initiated an antiretroviral therapy regimen between Jan 1, 2000, and Jan 9, 2015, and met the eligibility criteria for inclusion in our study. During follow-up, CD4 cell count was measured on average every 4·0 months and viral load every 3·8 months. 464 individuals died (107 in threshold 200 strategy, 157 in threshold 350, and 200 in threshold 500) and 1091 had AIDS-defining illnesses or died (267 in threshold 200 strategy, 365 in threshold 350, and 459 in threshold 500). Compared with threshold 500, the mortality HR was 1·05 (95% CI 0·86-1·29) for threshold 200 and 1·02 (0·91·1·14) for threshold 350. Corresponding estimates for death or AIDS-defining illness were 1·08 (0·95-1·22) for threshold 200 and 1·03 (0·96-1·12) for threshold 350. Compared with threshold 500, the 24 month risk ratios of virological failure (viral load more than 200 copies per mL) were 2·01 (1·17-3·43) for threshold 200 and 1·24 (0·89-1·73) for threshold 350, and 24 month mean CD4 cell count differences were 0·4 (-25·5 to 26·3) cells per µL for threshold 200 and -3·5 (-16·0 to 8·9) cells per µL for threshold 350. INTERPRETATION: Decreasing monitoring to annually when CD4 count is higher than 200 cells per µL compared with higher than 500 cells per µL does not worsen the short-term clinical and immunological outcomes of virally suppressed HIV-positive individuals. However, more frequent virological monitoring might be necessary to reduce the risk of virological failure. Further follow-up studies are needed to establish the long-term safety of these strategies.

RESUMO

INTRODUCTION: GESIDA and the AIDS National Plan panel of experts suggest preferred (PR), alternative (AR), and other regimens (OR) for antiretroviral treatment (ART) as initial therapy in HIV-infected patients for the year 2016. The objective of this study is to evaluate the costs and the efficacy of initiating treatment with these regimens. METHODS: Economic assessment of costs and efficiency (cost/efficacy) based on decision tree analyses. Efficacy was defined as the probability of reporting a viral load <50copies/mL at week 48 in an intention-to-treat analysis. Cost of initiating treatment with an ART regimen was defined as the costs of ART and its consequences (adverse effects, changes of ART regimen, and drug resistance studies) during the first 48 weeks. The payer perspective (National Health System) was applied, only taking into account differential direct costs: ART (official prices), management of adverse effects, studies of resistance, and HLA B*5701 testing. The setting is Spain and the costs correspond to those of 2016. A sensitivity deterministic analysis was conducted, building three scenarios for each regimen: base case, most favourable, and least favourable. RESULTS: In the base case scenario, the cost of initiating treatment ranges from 4663 Euros for 3TC+LPV/r (OR) to 10,894 Euros for TDF/FTC+RAL (PR). The efficacy varies from 0.66 for ABC/3TC+ATV/r (AR) and ABC/3TC+LPV/r (OR), to 0.89 for TDF/FTC+DTG (PR) and TDF/FTC/EVG/COBI (AR). The efficiency, in terms of cost/efficacy, ranges from 5280 to 12,836 Euros per responder at 48 weeks, for 3TC+LPV/r (OR), and RAL+DRV/r (OR), respectively. CONCLUSION: Despite the overall most efficient regimen being 3TC+LPV/r (OR), among the PR and AR, the most efficient regimen was ABC/3TC/DTG (PR). Among the AR regimes, the most efficient was TDF/FTC/RPV.

RESUMO

INTRODUCTION: For patients with late-stage (metastatic) breast cancer, the impact of treatment on health-related quality of life is a key factor in decision-making. A systematic review was conducted to identify health state utility values (HSUVs) for late-stage breast cancer, derived using methods preferred by health technology assessment (HTA) agencies, by treatment line. The aim was to generate a list of HSUVs, that could help to justify the values used to populate cost-utility models. Areas covered: Ten electronic databases, international congress websites and online HSUV databases were searched (January 1995-May 2014) for HSUVs for adults with late-stage breast cancer that had been derived from methods favoured by HTA agencies. Publications were included only if they reported studies that originated HSUVs. Expert commentary: Large numbers of HSUVs are available for late-stage breast cancer in the published literature. Contrary to expectations, the HSUVs reported in the literature vary greatly for some health states. As a result, the choice of HSUV can have considerable implications for the outcomes of economic evaluations. Standardization of HSUV methodology is expected to reduce variability; however, further research is recommended for assessing the sensitivity of generic preference-based measures in late-stage (metastatic) breast cancer.

RESUMO

OBJECTIVES: To evaluate the cost-effectiveness of treatment with anti-CD20 monoclonal antibody obinutuzumab plus chlorambucil (GClb) in untreated patients with chronic lymphocytic leukemia unsuitable for full-dose fludarabine-based therapy. METHODS: A Markov model was used to assess the cost-effectiveness of GClb versus other chemoimmunotherapy options. The model comprised three mutually exclusive health states: "progression-free survival (with/without therapy)", "progression (refractory/relapsed lines)", and "death". Each state was assigned a health utility value representing patients' quality of life and a specific cost value. Comparisons between GClb and rituximab plus chlorambucil or only chlorambucil were performed using patient-level clinical trial data; other comparisons were performed via a network meta-analysis using information gathered in a systematic literature review. To support the model, a utility elicitation study was conducted from the perspective of the UK National Health Service. RESULTS: There was good agreement between the model-predicted progression-free and overall survival and that from the CLL11 trial. On incorporating data from the indirect treatment comparisons, it was found that GClb was cost-effective with a range of incremental cost-effectiveness ratios below a threshold of £30,000 per quality-adjusted life-year gained, and remained so during deterministic and probabilistic sensitivity analyses under various scenarios. CONCLUSIONS: GClb was estimated to increase both quality-adjusted life expectancy and treatment costs compared with several commonly used therapies, with incremental cost-effectiveness ratios below commonly referenced UK thresholds. This article offers a real example of how to combine direct and indirect evidence in a cost-effectiveness analysis of oncology drugs.

RESUMO

OBJECTIVE: The role of cost-effectiveness analysis (CEA) in incentivizing innovation is controversial. Critics of CEA argue that its use for pricing purposes disregards the 'value of innovation' reflected in new drug development, whereas supporters of CEA highlight that the value of innovation is already accounted for. Our objective in this article is to outline the limitations of the conventional CEA approach, while proposing an alternative method of evaluation that captures the value of innovation more accurately. METHOD: The adoption of a new drug benefits present and future patients (with cost implications) for as long as the drug is part of clinical practice. Incidence patients and off-patent prices are identified as two key missing features preventing the conventional CEA approach from capturing 1) benefit to future patients and 2) future savings from off-patent prices. The proposed CEA approach incorporates these two features to derive the total lifetime value of an innovative drug (i.e., the value of innovation). RESULTS: The conventional CEA approach tends to underestimate the value of innovative drugs by disregarding the benefit to future patients and savings from off-patent prices. As a result, innovative drugs are underpriced, only allowing manufacturers to capture approximately 15% of the total value of innovation during the patent protection period. In addition to including the incidence population and off-patent price, the alternative approach proposes pricing new drugs by first negotiating the share of value of innovation to be appropriated by the manufacturer (>15%?) and payer (<85%?), in order to then identify the drug price that satisfies this condition. CONCLUSION: We argue for a modification to the conventional CEA approach that integrates the total lifetime value of innovative drugs into CEA, by taking into account off-patent pricing and future patients. The proposed approach derives a price that allows manufacturers to capture an agreed share of this value, thereby incentivizing innovation, while supporting health-care systems to pursue dynamic allocative efficiency. However, the long-term sustainability of health-care systems must be assessed before this proposal is adopted by policy makers.

RESUMO

INTRODUCTION: Although RTS as HIV Diagnosis was considered cost effectiveness [1], overall budget may be unaffordable for some countries. We explore Incremental cost per NDHI associated with different TS. MATERIALS AND METHODS: From a health care perspective, using direct costs and Euros currency, we calculated budget and cost per NDHI of RTS (all patients were tested), TTS (Universal risk practices and clinical conditions-RP&CC - only positive were tested), and CPTS (Only patients physicians considered were tested). We considered DRIVE (Spanish acronym of HIV infection Rapid Diagnosis) study and clinical Practice outcomes. Population between 18-60 years, attending to a Hospital Emergency Room or to a Primary Care Center performed an HIV RP&CC questionnaire (Q) and an HIV rapid test (HIV RT). Unitary costs considered were: HIV RT, nurse, registry, transport and HIV confirmation when necessary, imputed to all population in RTS and CPTS and only in HIV RP&CC-Q positive in TTS analysis, while HIV RP&CC-Q costs were added to all population in TTS. Sensitivity analyses were performed with varying rates of NDHI and of positive HIV RP&CC-Q population, and different RP&CC Q sensitivity (SE) to predict HIV infection. RESULTS: 5,329 HIV RP&CC-Q and HIV RT were performed to 49.64% women, median age 37 years old, 74.9% Spaniards. In DRIVE and CP, NDHI were 4.1‰, and 1.6‰, while HIV RP&CC-Q was positive in 51.2%. HIV RP&CC-Q SE was 100%. Overall budget employed in HIV testing was in RTS 43,503€, in TTS 24,472€ and in CPTS 5,032€. Cost per 1 NDHI was 1,977€, 1,112€ and 5,032€, respectively. A reduction in cost of 865€, favouring TTS vs. RTS, while an increased cost of 824€ in CPTS vs. RTS was obtained. Considering NDHI rate of 2.6‰ saving costs increased to 1379€ in TTS, while were reduced to 576€ if NDHI rate increases 6.2‰. Effect of RP&CC-Q positivity rate was similar, if 25% saving costs were 1368€, while if 75% were reduced to 399€. Varying SE of RP&CC-Q to 95%, 91% and 50% cost saving was 810€, 754€, and 208€, and number of MHI one, two and 11. CONCLUSIONS: In DRIVE study Targeted TS with universal screening of RP&CC before an HIV rapid test is cost saving, without missing NDHI, with respect to Routine TS. Lower rates of HIV infection and RP&CC in the population, increase costs savings.

RESUMO

This study was designed to investigate the persistence of lipodystrophy (LD)-related social distress and isolation in HIV-infected patients in the current era, according to confirmatory dual energy X-ray absorptiometry (DEXA) measurements. Cross-sectional interview data were collected from 168 HIV-positive adult patients taking more than 2 years of antiretroviral therapy (133 cases with LD diagnosed a mean of 7.2 years before; 35 without LD, controls). Mean time of HIV infection was 16.2 years (2.1-27.3), and the mean time of exposure to highly active antiretroviral therapy of 11.7 years (2.1-21.1). The presence and severity of LD, confirmed by DEXA measurements, correlated with social isolation through a validated scale, including avoidance of social relationships, sex, work, or sport activities. In comparison with control patients, social distress was observed for patients having moderate body changes. The significant correlation between LD and social isolation was irrespective of age, CD4+ count, HIV RNA level, AIDS diagnosis, time of HIV infection, anxiety, or depressive symptoms. These results confirm that patient assessment of LD is correlated with whole-body DEXA scan, and they highlight the role of LD as an independent cause of social isolation even after years of the diagnosis.

RESUMO

OBJECTIVE: To increase equitable access to life insurance for HIV-positive individuals by identifying subgroups with lower relative mortality. DESIGN: Collaborative analysis of cohort studies. METHODS: We estimated relative mortality from 6 months after starting antiretroviral therapy (ART), compared with the insured population in each country, among adult patients from European cohorts participating in the ART Cohort Collaboration (ART-CC) who were not infected via injection drug use, had not tested positive for hepatitis C, and started triple ART between 1996-2008. We used Poisson models for mortality, with the expected number of deaths according to age, sex and country specified as offset. RESULTS: There were 1236 deaths recorded among 34,680 patients followed for 174,906 person-years. Relative mortality was lower in patients with higher CD4 cell count and lower HIV-1 RNA 6 months after starting ART, without prior AIDS, who were older, and who started ART after 2000. Compared with insured HIV-negative lives, estimated relative mortality of patients aged 20-39 from France, Italy, United Kingdom, Spain and Switzerland, who started ART after 2000 had 6-month CD4 cell count at least 350 cells/µl and HIV-1 RNA less than 104 copies/ml and without prior AIDS was 459%. The proportion of exposure time with relative mortality below 300, 400, 500 and 600% was 28, 43, 61 and 64%, respectively, suggesting that more than 50% of patients (those with lower relative mortality) could be insurable. CONCLUSION: The continuing long-term effectiveness of ART implies that life insurance with sufficiently long duration to cover a mortgage is feasible for many HIV-positive people successfully treated with ART for more than 6 months.

RESUMO

OBJECTIVE: To develop and test a decision-support tool for prioritizing new competing Health Technologies (HTs) after their assessment using the mini-HTA approach. METHODS: A two layer value/risk tool was developed based on the mini-HTA. The first layer included 12 mini-HTA variables classified in two dimensions, namely value (safety, clinical benefit, patient impact, cost-effectiveness, quality of the evidence, innovativeness) and risk (staff, space and process of care impacts, incremental costs, net cost, investment effort). Weights given to these variables were obtained from a survey among decision-makers (at National/Regional level and hospital settings). A second layer included results from mini-HTA (scored as higher, equal or lower), which compares the performance of the new HT (in terms of the abovementioned 12 variables) with the available comparator. An algorithm combining the first (weights) and second (scores) layers was developed to obtain an overall score for each HT, which was then plotted in a value/risk matrix. The tool was tested using results from the mini-HTAs for three new HTs (Surgical Robot, Platelet Rich Plasma, Deep Brain Stimulation). RESULTS: No significant differences among decision-makers were observed as regards the weights given to the 12 variables, therefore, the median aggregate weights from decision-makers were introduced in the first layer. The dot plot resulting from the mini-HTA presented good power to visually discriminate between the assessed HTs. CONCLUSION: The decision-support tool developed here makes possible a robust and straightforward comparison of different competing HTs. This facilitates hospital decision-makers deliberations on the prioritization of competing investments under fixed budgets.
