We retrieved 273 records; 98 records were excluded due to duplication. During the initial stage, 160 references, including letters to the editor and articles addressing the effect of sanctions on areas other than health, were excluded on examination of the title and abstract. In the next stage, 15 articles were chosen for full-text reading, out of which 11 studies were included. The flow chart in Fig. 1 illustrates our selection process.
Therefore, ten out of eleven included studies addressed the effects of sanctions on access to medicine in Iran. Three articles studied medicines holistically,[16–18] seven articles investigated medications related to some specific diseases,[19–25] and the one remaining assessed the effect of sanctions on air pollution.[26] In terms of method, there were 6 quantitative studies, 4 qualitative studies, and one review (Fig. 2). In order to data collection, studies used media, information obtained from city pharmacies, chart review and question from patients,[19, 20, 22, 25]national reports,[18, 23] and literature review.[18, 24] The characteristics of included studies are demonstrated in Table 1.

Summery of the included studies
ID | First author | Aim/s | Main finding(s) |
1 | Mostafavi SM.[26] | Studying the relationship between economic sanctions and rise in air pollutants | Economic sanctions have had a significant relationship with CH4, CO2, and NOx air pollutants, in the years intervening 2001 and 2013. |
2 | Ghiasi G.[21] | Examining the Impact of sanctions on availability to asthma medicines in Tehran,a before-after study. | The availability of asthma medicines in pharmacies has dramatically decreased. Service delivery arrangement |
3 | Kheirandish M.[16] | Analysing the news media of sanction effects on access to medicine | Sanctions negatively effect on access to medicines in Iran; also the number of news media reporting shortage of medicine have had increased from 2011–2013. |
4 | Shahabi S.[24] | Reviewing the literature and documents regarding the impact of international economic sanctions on Iranian cancer health care | Increase in medicines’ price, in addition to the bankruptcy of pharmaceutical factories, has led more than 6 million patients with non-communicable diseases (including cancer) not to get high-quality treatment for their disease. Besides the use of benzene containing gasoline has raised people's exposure to carcinogenic agents. |
5 | Karimi M.[22] | Studying the effects of economic sanctions on clinical outcomes of patients with thalassemia and hemophilia in Iran | People living with thalassemia and hemophilia, due to sanctions do not have enough access to iron chelators, and coagulation factor concentrates, and are developing more disease specified complications. |
6 | Deilamizade A.[20] | Addressing the effect of sanctions on illicit drug use | A sharp rise in drug prices has encouraged drug users to use less expensive and more harmful drugs, through more hazardous routes such as intravenous. |
7 | Asadi-PooyaAA.[19] | A retrograde chart reviewing to investigate the effects of sanctions on drug adherence among patients with epilepsy | Reduction in drug adherence was close to being significant (P = 0.07) before and after 2012; despite some drugs were unavailable after sanctions, and others were much more expensive. Medicine subsidization by the government seems to play an important role. |
8 | Setayesh S.[17] | Addressing the impact of economic sanctions on Iranian drug shortages, using major pharmacies and news media as sources of data | Of 73 medicines in shortage, almost 50% were in the WHO Essential Medicine List, and 89% were related to NCDs. |
9 | Kheirandish M.[23] | Examining the effect of sanction on access to non-communicable diseases medicines | Among drugs for the treatment of cancer, multiple sclerosis, diabetes, and asthma, asthma and cancer groups are in severe shortage in Iran's pharmaceutical market. Also impacts were higher after sanctioning Central Bank of Iran. |
10 | Aloosh M.[18] | Addressing the health impact of sanctions in Iran and some other countries, using Central Bank data and the literature review. | In addition to decrease in drugs availability, the GDP and employment rate have been lowered, and death rate due to self-harm and admissions for mental health issues has risen in the sanction period. Greece and Honduras had the same situation during economic recession. |
11 | Asadi-PooyaAA[25] | Patient survey addressing if there has been changes in the experience of patients with epilepsy, regarding access to Anti-Epileptic Drugs, during past six months. | After intensification of sanctions, some commonly used AEDs are scarcely available, with 53% of patients reporting it. Increase in prices and the obligation to substitute the routine medications with more available ones added to the hardship felt by patients. |
Among studies illustrated in Table 1, Shahabi et al.[24] Reviewed the literature assessing the impact of international economic sanctions on Iranian cancer health care. They found that economic crisis due to sanction has led more than 6 million patients with NCDs (including cancer) not to get high-quality treatment for their disease. Besides the use of benzene containing gasoline has raised people's exposure to carcinogenic agents.
Following three studies are somehow based on the data of gray literature, and they did not collect primary data from the field. Kheirandish et al.[16] searched content of media and issued magazines in Iran between 2011 and 2013 (a year before and after 2012) for words “medicine” or “drug”, and their Farsi equivalent (i.e., “Daru”); data sources mostly consisted of Magiran, Tabnak website, Iran's Ministry of Health and Medical Education news website (Webda), and Sepid weekly magazine. Similarly, Setayesh and Mackey[17] made a list of drugs in shortage in 2012 and 2013, using the report of the International Institute for Peace Justice and Human Rights,[27] and news media, i.e. Khabar Online and Parsine News as Persian sources; and compared the list with WHO Essential Medicine List and EAR99 List. Aloosh et al.[18] Assessed the World Bank and central bank data and matched them with the literature. The GDP and employment rate have been lowered, and death rate due to self-harm and admissions for mental health issues has risen in the sanction period. Briefly, medication shortage has been more experienced during the sanction period, and also economic indices have been affected.
Keirandish et al.[23] Also used Iran Drug List and Iran Pharmaceutical Registry, to assess the availability and sale of medicines being used for the treatment of diabetes, asthma, cancers, and multiple sclerosis, for 68 months from 2008 to 2013. Ghiasi et al.[21] Interviewed pharmacists working at 44 pharmacies around Tehran, and collected data related to the availability of imported and locally produced medicines for the treatment of asthma, at July 2012 and March 2013, and compared the results. Karimi and Haghpanah[22] also asked 20 health care professionals who were involved in the care of patients with thalassemia and hemophilia to fill out a questionnaire addressing the changes in the availability, affordability and the usage of the disease-specific medications over past years. Beside this, they reviewed medical records of 69 thalassemia and 40 hemophilia patients and evaluated patients' clinical outcomes at three time points of 2006, 2009 and 2012.
Asadi-Pooya et al.[19] Asked epileptic patients under care at the epilepsy clinic at Shiraz University of Medical Sciences about their drug adherence, and possible causes of poor adherence in patients. They compared data obtained in the two study periods 2010–2011 and 2012–2013. [20]. Similarly Asadi-Pooya et al[25] on 2019, assessed patients’ experience in access to AEDs, anf if there has been any change in their experience during past six months. Deilamizade & Esmizade[20] interviewed 48 drug users living in Tehran for their prevailing economic and social conditions that they faced, and their reactions to such conditions after sanctions.
All above studies reached similar results of medication and drug shortage, and somehow increase of disease specific complications during sanctions period.
Mostafavi et al.[26] Used a different perspective addressing causal relationship between economic sanctions, macroeconomic variables (i.e., value-added of industry, mine, and oil sectors and non-oil GDP( and environmental polluters (i.e., CH4, CO2, and NOx). In order to address this causal relationship, they used the "Hsiao causality approach" which analyses the null hypothesis using time series data (2001–2013 in this study) and descriptive statistics theories. Finally, the causal relationship between economic sanctions the rise in CH4, CO2 and NOx levels was demonstrated.[26] This was the only study found addressing the effects of sanctions on other social determinants of health than healthcare.
