The medical consultation is one of the requirements in diseases diagnosis and patient treatment. In addition, a high-quality consultation is a fundamental demand of patients, and it is one of the rights of every patient. The purpose of this paper is to identify factors affecting the high-quality consultation in medical communications.

The following electronic databases were searched: MEDLINE (via PubMed), Web of Science, Cochrane, EMBASE, Scopus and ProQuest until December 2018. In addition, the authors searched Google Scholar. Qualitative and quantitative studies were assessed using the Critical Appraisal Skills Programme, Qualitative Checklist and the Center for Evidence-Based Management appraisal checklist, respectively. A stepwise approach was conducted for data synthesis.

Of 3,826 identified studies, 29 met the full inclusion criteria. Overall, after quality assessment of studies, 25 studies were included. The studies were conducted in the USA (n=6), the UK (n=6), the Netherlands (n=4), Canada (n=2), Belgium (n=2), Poland (n=2), Germany (n=1), Iran (n=1), Finland (n=1), Austria (n=1), Qatar (n=1), Denmark (n=1) and China (n=1), and five studies were excluded. Data synthesis showed that high-quality consultation consisted of three main categories: structural (4 main themes with 26 sub-themes), process (2 main themes with 33 sub-themes) and outcome (3 main themes with 12 sub-themes) quality.

Using the indicators of consultation quality improvement can develop physicians’ clinical competence and skills. Decision makers can use them to monitor and evaluate physicians’ performance. A high-quality consultation can be useful in social prescribing that helps patients to manage their disease.

Hospital accreditation has been adopted internationally as a way and solution for healthcare quality improvement in hospitals. The purpose of this study was to review and knowledge mapping of bibliographic data about “Hospital Accreditation” and assess the current quantitative trends.

Scientometric methods and knowledge visualization using the coword analysis techniques conducted in three steps based on the data related to the field of hospital accreditation from 1975 to 2018 obtained from the MEDLINE database. Bibliographic data for titles, abstracts and keywords articles were saved in CSV format and MEDLINE templates by applying filters. Data extracted were exported into an Excel spreadsheet and were preprocessed. The authors applied the text mining and visualization using VOSviewer software.

Hospital accreditation studies have been increased rapidly over the past 30 years. 6,661 documents in the field of hospital accreditation had been published from 1975 to 2018. Hospitals or organizations active in the field of hospital accreditation were in the United States, Italy and Canada. The 10 most productive authors identified in the area of hospital accreditation with a higher influence were identified. “The United States”, “accreditation”, “Joint commission on accreditation” and “quality assurance, healthcare” had, respectively, the highest frequency. The cluster analysis identified and categorized them into four major clusters. Hospital accreditation field had a close relationship with the quality improvement, patient safety, risk and standards.

Hospital accreditation had focused on the scopes of implementation of accreditation programs, adherence to JCI standards, and focus on safety and quality improvement. Future studies are recommended to be conducted on design interventions and paying attention to all dimensions of hospital accreditation.

This study aims to investigate blockchain technology (BT) and its opportunities and weaknesses in Iran's tax system; it addresses the opportunities and challenges of BT when incorporated into Iran's tax system.

The statistical population consists of all the employees and managers working in tax administration, and 674 participants were selected as the sample size via Cochran sampling. The partial least square tests are used to investigate the impact of the independent variable on dependent ones.

The results show that BT positively affects three components of tax, including value-added tax, tax on shipping goods and income tax. BT’s advantages and opportunities positively affect these taxation types, while its threats negatively affect the opportunities and challenges in Iran’s tax system; this study provides helpful insights and develops the knowledge. Furthermore, this is among the initiatives addressing BT’s opportunities and challenges in three discriminative taxation sectors, including value-added tax, tax on shipping goods and payroll tax.

Since no study has addressed BT’s opportunities and weaknesses in Iran’s tax system, it addresses the opportunities and challenges of BT when incorporated into Iran’s tax system.
