Background

COVID-19 pandemic has put a lot of pressure on the health systems of countries around the world [1, 2]. The burden of infection and the high mortality and morbidity rates have led health systems to do their utmost to combat it. The national health services of the affected countries faced lack of funding, inadequate finance, deprivation of human and technical resources, and rigid and fragmented health policy-making [1, 3].

The coronavirus pandemic, directly and indirectly, has affected health service provisions in all parts of the health system, including reproductive health services such as maternity care, family planning, and sexual health [4, 5]. Coronavirus infection and its complications in mothers increased the need for special care in the obstetrics ward. Fear, stigma, misinformation, and socioeconomic factors including restrictions, lack of financial resources, reduced economic activity, and reduced government revenues indirectly affected the access to essential reproductive health services [4,5,6].

Reduction in access to and utilization of essential reproductive health services during the coronavirus pandemic increased the number of women who suffer from complications or die during pregnancy [7, 8]. An abortion, or termination of pregnancy, is a procedure to end a pregnancy. Abortion services include ending pregnancy either by taking medicines or having a surgical procedure. In addition, abortion services and stock-out of contraceptives to prevent unintended pregnancies are disrupted [7,8,9]. A 10% reduction in service coverage during reproductive age could result in the death of an additional 28,000 mothers, over 3.3 million unsafe abortions, and 15.4 million unintended pregnancies as family planning services face disruptions [8, 10]. Access to sexual health services and safe abortion reduced in many countries in COVID-19 pandemic lockdowns. This issue can increase the mortality of adolescent women and girls who are more vulnerable to unintended pregnancies than others [9].

Unsafe abortion is one of the most critical problems of reproductive health services, which is more common in middle and low-income countries. That is due to the lack of access to legal abortion services and financial resources [11, 12]. About 7 million women are admitted to hospitals in these countries every year due to the complications of unsafe abortion. Annually, about 4.7 to 13.2% of maternal deaths occur due to unsafe abortion, and the cost of management of the complications of unsafe abortion is estimated at US$ 553 million [12, 13].

Concerning the morbidities and high burden of unsafe abortions, in cases where safe abortion services are limited or are not available, people resort to using herbs or drugs or surgical procedures from unknown and often unsafe sources to terminate their pregnancies [14]. Some countries have recognized this risk during the COVID-19 pandemic and have allowed people with remote counseling or telemedicine to take some medications at home to avoid abortion with mentioned methods [14]. Therefore, some studies suggest that in these situations, health systems can use telemedicine, virtual and social networks to provide education and counselling on contraceptive methods or safe drugs for induced abortion to prevent the risk of unsafe abortion [15].

Global efforts were made in a crucial circumstance like this to quickly create safe and effective vaccinations. The first COVID-19 vaccination was ultimately authorized by the American Food and Drug Administration in August 2021 [16]. After immunization with this vaccine, fertility doesn’t appear to be impaired [16]. In these situations, it seems necessary to provide education and counselling about safe sexual health to prevent coronavirus infection, care before and after using contraceptive or abortion methods in the current pandemic. Despite numerous studies, some questions remain unanswered, including the impact of pandemic on the services for abortion and post-abortion and the strategies should the health systems adapt to manage abortions in the current pandemic. So far, no study has integrated all the strategies and practical approaches to administering this issue. Therefore, in this study, we intend to systematically review the studies investigating management of health services to abortions during the COVID-19 pandemic.

COVID-19 and abortion

The results showed that during the COVID -19 pandemic, requests for access to medication abortion by telemedicine and demand for self-managed medication abortion had been increased [20,21,22,23,24, 26, 28, 29, 34,35,36]. In contrast, the number of abortion requests and procedures in the abortion centers were generally dropped [31]. It was more significant in the most severe and longest-lasting lockdowns [28]. In another report, the number of visits to abortion clinics has been reduced by 32%, with an additional 23% reduction in areas where abortion is prohibited [18]. Travel restrictions [32], lockdowns [22, 27, 28], and fear of COVID-19 [17] were among reasons to choose telemedicine abortion. Request for telemedicine abortion was reported based on location and distance from the hospital [32].

Satisfaction in telemedicine service

Numerous studies described tele-abortion safe, effective [20, 29, 32], very acceptable [20, 32, 34], and satisfying for women [23, 26, 29]. More individuals preferred medical abortion to surgical abortion [17]. In one study, the most frequent reasons to choose telemedicine abortion were privacy (38.3%), secrecy (46.2%), and comfort (34.9%) [22].

According to the results of a qualitative research, the quality of abortion care was improved in telemedicine services due to access, comfort, flexibility, and ongoing telephone support [20, 32]. It also reported that self-sourced medication abortion was safe, effective, and empowering for women [32, 33]. Another report showed no significant difference in satisfaction of services during and after lockdown (p = 0.690) [17].

Complications and challenges of tele-abortion

The most reported complications of mothers were bleeding [24, 34], pain [24, 34], and need to blood transfusions (0.4%) [26]. The COVID-19 pandemic had created many challenges in abortion clinics, including changes in the work style of healthcare providers, increased costs, and reduced revenue, but care activities continued [37, 38]. Using medication abortion and present telemedicine services without ultrasound has also been reported [20, 23, 33].

Discussion

Our results may indicate two different aspects. First, Increased rates of miscarriage throughout the pandemic may be due to the risk of COVID 19 during pregnancy, decreased access to prenatal care, or the financial downturn associated with the pandemic [39, 40]. Second, Decrease the rate of clinics appointments for abortion and increase the number of self-managed abortions, which can be due to fear of infection during the on-site visit or inability to go to the clinic due to disruption of the transportation system or childcare. We recognized higher stay-at-home behaviour levels with significant increases in requests in support of these probabilities. Studies have found that barriers to accessing the clinic, especially the cost of abortion, are reasons that individuals often cite. These barriers were reflected at the individual level at the state level, where the highest rates of applications were related to the residence in states with more restrictive abortion policies. There was also a correlation between the increase in the rate of requests in the counties, where the mean distance between nearest abortion clinics was longer, and the high proportion of the population living below the FPL [27], for example Texas, the state with the most prohibitive criteria, showed the greatest rise in requests, notwithstanding an almost low burden of COVID-19 [28]. International human rights law explicitly accredits the rights to sexual and reproductive health and autonomy of the body. These rights create a positive commitment by the government to provide information and services related to abortion and remove unnecessary medical barriers that eliminate practical access [41]. In times of crisis like pandemics, the international human rights commitments of states to respect, protect, and achieve the rights to health, life, and indiscrimination, among other rights, are not suspended. Steps to limit unsafe abortions and assure access to essential sexual and reproductive health services, such as abortion services, are key responsibilities of governments, even in emergencies. Achieving this main obligation demands the repeal of laws and procedures that criminalize, impede, or impair access to sexual and reproductive services, ensure public access to services, and limit unsafe abortions [42, 43]. Reaching these main obligations is vital and necessary in the time of COVID-19. Government responses that have promoted access to self-managed abortion are necessary steps to improve agreement with human rights obligations. Governments must fulfill similar proof-based and transformative solutions to guarantee abortion access for those who need a surgical abortion or those who do not have independence or basic support to offer self-managed abortion. States must more anticipate and deal with medical deficiencies due to interrupted supply chains. Other critical measures such as guaranteeing that telemedicine and other abortion services are possible to marginalized groups for free or at a low price. The results of a qualitative study showed that one of the common and positive experiences of maternal health care providers during the COVID-19 pandemic was the use of telemedicine capacity to care pregnant women that was beneficial in relieving their anxiety and breaking the chain of COVID-19 transmission [44]. However, telemedicine does not apply to all women and in all areas. Lack of adequate internet connection in some places prevents the widespread use of telemedicine [45].

Limitations

This study has several limitations. First, even more than a year after the beginning of the COVID-19 epidemic, many aspects of reproductive health and abortion services are still unknown due to the lack of related articles. Second, existing studies sometimes report disparate material that cannot be discussed in the desired detail (because both our knowledge of the epidemic and its effects is rapidly increasing, and the results of the studies presented from different communities based on social and indigenous situations. Last, the present study was supposed to be done as a meta-analysis, but due to factors such as: the scarcity and heterogeneity of existing articles, the unknown nature of the disease, and its effects on reproductive health (including abortion), it was practically not possible.

Suggestions

Based on the results and limitations of the study, in order to achieve more and better results, the following items are suggested:

  1. 1.

    Conducting studies with a wider range and more diverse variables regarding reproductive health and pregnancy.

  2. 2.

    Investigating and comparing the effects and complications of COVID-19 on reproductive health in different communities.

  3. 3.

    Investigating the effect of vaccination on the consequences of pregnancy and abortion (when we did this study, vaccination of pregnant women had not been done and we could not investigate the consequences of vaccination on pregnancy and abortion).

Overall, this study presents new findings on the impact of COVID-19 on aspects of abortion that can be used by reproductive health care providers to manage the complications of abortion.

Conclusion

COVID-19 is a pandemic, which implies that global values need to be considered. It appears that countries with strict rules must revise their abortion laws throughout pandemics to decrease the unsafe abortions rate and their complications. The COVID-19 emergency is urging states to extend their healthcare systems and review their health laws. Women could suffer urgent harm if the restricted law is not repealed. Evidence suggests that COVID-19 may impair reproductive health, directly or indirectly. Given the effects of the COVID-19 epidemic on reproductive health, the results of this study provide detailed information on the various aspects of abortion and how to manage it in pandemic conditions. The findings of this study can be used by reproductive health care providers and policy makers to address the complications of abortion management.
