Objectives: The objective of this systematic review was to evaluate the cost-effectiveness of interventions aiming to increase the adherence to highly active antiretroviral therapy (HAART) in HIV-infected patients in developed countries (WHO stratum A).Methods: A systematic search for comparative health economic studies was conducted in the following databases: EMBASE, MEDLINE, NHS Economic Evaluation Database, CINAHL, HEED, and EconLit. The identified publications were selected by two reviewers independently according to predefined inclusion and exclusion criteria. Furthermore, these were evaluated according to a standardized checklist and finally extracted, analyzed, and summarized.Results: After reviewing the abstracts and full texts four relevant studies were identified. Different educational programs were compared as well as the Directly Observed Therapy (DOT). A critical aspect to be considered in particular was the poor transparency of the cost data. In three cost-utility analyses the costs per quality-adjusted life-year (QALY) in the baseline scenario were each under USD 15,000. The sensitivity analyses with a presumed maximum threshold of USD 50,000/QALY showed a predominantly cost-effective result. In one study that examined DOT the costs add up to over USD 150,000/QALY.Conclusions: It seems that adherence interventions for HAART in HIV-infected patients can be cost-effective. Nevertheless, the quality of the included studies is deficient and only a few of the possible adherence interventions are taken into consideration. A final assessment of the cost-effectiveness of adherence interventions in general is, therefore, not possible.

Background: Cladribine tablets are the foremost oral immune-reconstitution therapy for high disease activity relapsing multiple sclerosis (HDA-RMS). We aimed to assess the cost-effectiveness of cladribine tablets compared to natalizumab in patients with HDA-RMS in Iran. Methods: A 5-year cohort-based Markov model was developed with 11 expanded disability status score (EDSS) health states, including patients with HDA-RMS as on and off-treatment. All costs were identified from the literature and expert opinion and were measured in Iranian Rial rates, changed to the 2020 USD rate and were discounted by 7.2%. Quality adjusted life years (QALY), discounted by 3.5%, and life years gained (LYG) were adopted to measure efficacy. The final results were presented as incremental cost-effectiveness ratio that was compared to a national willingness to pay (WTP) threshold of 1 to 3 gross domestic product (GDP) per capita. Deterministic and probabilistic sensitivity analyses (D/PSA) were employed to evaluate uncertainty. Results: Cladribine tablets dominated natalizumab and yielded 6,607 USD cost-saving and 0.003 additional QALYs per patient. LYG was comparable. The main cost component was drug acquisition cost in both arms. DSA indicated the sensitivity of the results to the cost discount rates and also the patients’ body weight; while they were less sensitive to the main clinical variables. PSA indicated that cladribine tablets were cost-effective in Iran, with a probability of 57.5% and 58.6% at lower and higher limits of threshold, respectively. Conclusion: Cladribine tablets yielded higher QALYs and lower costs compared to natalizumab, in patients with HDA-RMS in Iran.

Abstract Background: Adherence to highly active antiretroviral therapy (HAART) is a public health challenge worldwide. Non-adherence to HAART leads to treatment, immunologic, and virological failure. Despite different interventions made, adherence to HAART among adult people living with HIV (PLWHIV) is still inconsistent across studies, and the effect of serostatus disclosure on adherence to HAART was not studied in Ethiopia. Therefore, the study is aimed to determine the pooled prevalence of adherence to HAART and its relationship with serostatus disclosure among adult PLWHIV in Ethiopia.Methods: We searched 3247 original articles, both published and unpublished on Ethiopia dated from January 2016 to November 2019 by using different search engines. Data were extracted using Microsoft excel. New Castle Ottawa Scale quality assessment tool was used. STATA software version 11 was used for analysis. A random-effects model for meta-analysis was computed. Cochran Q statistics and I2 were used to estimate heterogeneity. Egger’s and Begg’s test was used to assess the publication bias.Results: A total of fifteen articles for systematic review and four articles for meta-analysis were used. The pooled prevalence of adherence to HAART is found to be 81.19% (80.1, 82.3). In the subgroup analysis, the pooled prevalence of adherence to HAART was 79.82% (73.19, 86.45) in the Oromia region, 82.51 %( 73.14, 91.87) in the Amhara region, and 72.7% (63.78, 81.61) in the Southern Nations Nationalities and Peoples’ Region (SNNPR). The serostatus disclosure improves adherence to HAART by nearly three times compared to non-serostatus disclosed PLWHIV (AOR=2.99, 95 %CI: 1.88, 4.77).Conclusions: The pooled prevalence of adherence to HAART among adult PLWHIV in Ethiopia was found to be low compared to WHO antiretroviral treatment recommendations. Having serostatus disclosure improved adherence to HAART.

OBJECTIVEAs the cost of health care continues to increase, there is a growing emphasis on evaluating the relative economic value of treatment options to guide resource allocation. The objective of this systematic review was to evaluate the current evidence regarding the cost-effectiveness of cranial neurosurgery procedures.METHODSThe authors performed a systematic review of the literature using PubMed, EMBASE, and the Cochrane Library, focusing on themes of economic evaluation and cranial neurosurgery following the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines. Included studies were publications of cost-effectiveness analysis or cost-utility analysis between 1995 and 2017 in which health utility outcomes in life years (LYs), quality-adjusted life years (QALYs), or disability-adjusted life years (DALYs) were used. Three independent reviewers conducted the study appraisal, data abstraction, and quality assessment, with differences resolved by consensus discussion.RESULTSIn total, 3485 citations were reviewed, with 53 studies meeting the inclusion criteria. Of those, 34 studies were published in the last 5 years. The most common subspecialty focus was cerebrovascular (32%), followed by neurooncology (26%) and functional neurosurgery (24%). Twenty-eight (53%) studies, using a willingness to pay threshold of US$50,000 per QALY or LY, found a specific surgical treatment to be cost-effective. In addition, there were 11 (21%) studies that found a specific surgical option to be economically dominant (both cost saving and having superior outcome), including endovascular thrombectomy for acute ischemic stroke, epilepsy surgery for drug-refractory epilepsy, and endoscopic pituitary tumor resection.CONCLUSIONSThere is an increasing number of cost-effectiveness studies in cranial neurosurgery, especially within the last 5 years. Although there are numerous procedures, such as endovascular thrombectomy for acute ischemic stroke, that have been conclusively proven to be cost-effective, there remain promising interventions in current practice that have yet to meet cost-effectiveness thresholds.
