Covid-19 first documented in late 2019 [1], quickly spread around the world, infecting tens of millions [2]. It was classified as a public health emergency of international concern and declared a pandemic by the World Health Organization in March 2020 [1]. It reached all continents in a short time [1]. Pregnant women, especially those with pathological pregnancies, were not spared. Covid-19 has led to many changes in the way health systems work [3]. These changes have impacted many actors in maternity services including women, support persons, midwives, medical staff and students [3].

In addition to Covid-19 outbreaks, the impact of the pandemic and response on health structures, communities and the global economy can also affect maternal health globally and in Senegal in particular [4]. There has been a significant decline in the use of services in most structures [5]. This may increase the number of out-of-hospital deaths related to other diseases. Several studies have shown an impact of this pandemic on patients and providers of maternal health services [6]. Stress, the anxiety of pregnant women, isolation of health personnel and change in the practice of care were often mentioned, in addition to excess mortality [5] [6].

To our knowledge, no research has yet been done in Senegal on the effect of the Covid-19 pandemic on pathological pregnancies. The rationale behind this study was to assess the effect of Covid-19 on prenatal consultations (PNCs) for pathological pregnancies at the Abass NDAO Hospital Centre (CHAN).

In total, 690 records of pregnant women with pathological pregnancies were collected: 375 prenatal records (54%) in the pre-pandemic period compared to 315 during Covid-19 (46%). In this study, the pre-Covid-19 period is from June 2019 to February 2020 and the Covid-19 period is from March to November 2020.

In terms of the period before COVID-19, the frequency of prenatal consultations on pathological pregnancy in November and December 2019 was 8.12% and 7.68% respectively. From March 2020 to May 2020, this frequency was respectively 2.75%, 4.64% and 2.46%. The frequency of prenatal consultations was 5.22% in June 2020, gradually increasing to 8.70% in September 2020, then decreasing in October and November 2020 (see Figure 1). The trend test showed a statistically significant difference between the observed monthly frequencies with a p value < 0.01.

The average age of women was 28.15 years. The age group 25 and 34 was the most represented with 36.81%. Women under 25 years of age accounted for 33.33% and women aged 35 and over for 19.86% (see Table 1).

Reasons for consultation were dominated by threats of premature delivery with 51.01% of cases followed by severe pre-eclampsia 15.07% of cases and premature membrane rupture with 11.01% of cases respectively. Pregnant vomiting accounted for about 9% of cases. Gestational diabetes and fluid discharge each accounted for 4%, high blood pressure (HBP) 3% (see Table 1).

In terms of assessing the functionality of the maternity service, the health staff involved in the management of pathological pregnancies (n = 21) consisted mainly of midwives (71.40%) and gynecologists (28.60%).

And 95% of agents reported working 5 days a week before the Covid-19 pandemic (see Figure 2). During the pandemic more than the majority of staff (67%) had worked only 3 days a week, 24% of health care staff had worked 5 days. Only 9% of officers were present 6 days a week (see Figure 2).

Among health care providers, 86% of cases worked 8 hours a day before Covid-19. During the pandemic, more than the majority worked 8 hours a day (57%). And 5% of the officers worked only 5 hours (see Figure 3). There was a decrease in qualified staff by 91% of health personnel. The majority of staff (60%)

reported being overworked during the coronavirus pandemic. Among health care providers, 43% of cases noticed a decrease in workload during the pandemic. Non-compliance with consultation days was noted in 38% of health providers. The two reasons cited were absence of pregnant women (37%) and confinement (63%). However, the majority of midwives and gynecologists (62%) reported seeing patients regularly. For patients, non-adherence to consultation appointments was noted in 86% of cases depending on the provider. Protective equipment was not provided to 14% of the staff. Difficulties encountered in the management of pathological pregnancies were noted in 81% of cases. Midwives and gynecologists at prenatal consultations noted fear of occupational exposure (12%) and patient reluctance (88%). Hygiene and protection measures were followed by 91% of health providers during the management of pathological pregnancies.

This study examined the effect of Covid-19 on prenatal consultations (PNCs) visits for pathological pregnancies and showed a significant reduction in attendance at the Maternity Ward for pathological pregnancy during the Covid-19 pandemic from March 2020 to May 2020. This could be explained on the one hand by the number of health workers redeployed for the pandemic response, and on the other hand by the risk of occupational exposure to Covid-19. The incidence among health workers leads to occupational unavailability and also the reluctance of pregnant women to attend health facilities. This finding has been mentioned by several authors, particularly Brazilian [7] [8]. In Niger, Abdoulaye M and Moynihan [9] [10] reported a decline in the use of curative services during the pandemic. For Abdoulaye M the drop in service attendance was noted in some districts by nearly 60% in the second quarter of 2020 compared to the same period in 2019 [9].

From June 2020 to September 2020, the gradual revival of rated NHC activities would be linked to a good communication policy and strategies to combat maternal mortality. This growing trend is followed by a decrease in the frequency of prenatal consultations (PNCs). The pace of the NHC frequency curve appears to follow the dynamics of the pandemic at the national level. Restriction measures are most observed during periods of epidemic peak. This finding was mentioned by Ndiaye O et al. in their pediatric study who noted an average reduction of 19% in visits, meaning a significant decrease in service attendance. And despite all the development strategies, this decline was more marked in March 2020 by 33% [5]. In fact, a World Health Organization study [11] found significant disruptions in health services among low-income countries. In our study, difficulties encountered by midwives and gynecologists during prenatal consultations are of two kinds: fear of occupational exposure to Covid-19 (12%) and reluctance of patients (88%). In Senegal, Sougou et al. in a study in the Dakar suburbs, shared the same observation [12]. In Egypt, a study showed that there was a positive correlation between knowledge scores about Covid-19 and the attitudes of claimants [13]. In the same study, 83.1% of health care providers reported a fear of being infected with Covid-19 [13].

Some authors noted psychological disorders during Covid-19 and these were more pronounced among younger women than men, and among nurses than physicians [14] [15]. In our study, claimants mentioned an experience of work overload during the pandemic, which could suggest signs of burn-out.

Non-adherence to prenatal appointments was noted by 86% of caregivers. This can lead to complications of pregnancy and even increase maternal deaths. These deaths can be indirectly related to the pandemic.

As a result, efforts must be made to develop programs and should develop strategies to catch up on missed consultations in order to avoid an increase in morbidity and maternal mortality. For example, Roberton T et al. in a recent study on modelling the indirect effects of the COVID-19, predicted an increase in maternal and infant mortality in developing countries that could be partly related to the decline in coverage of service provision [16]. In Nigeria, guidelines for medical consultations and telephone counselling should be established for non-emergencies to avoid unnecessary hospital visits [17]. In China, telemedicine has contributed to the reduction of psychological disorders in pregnant women [18].

In our study, 38% of health care providers reported non-compliance with the consultation days. The two reasons cited were absence of pregnant women (37%) and confinement (63%). This is consistent with the literature that noted a reduction in critical maternal health interventions during the pandemic period in many countries [19] [20].

Protective equipment was not provided to 14% of the staff. Indeed, the WHO noted that the underlying causes of the existing disruptions, with transport malfunctions, insufficient personal protective equipment, insufficient personnel and a lack of inventory, impact low- and middle-income countries to a greater extent [21].

The frequency of prenatal consultations (PNCs) of pathological pregnancies seems to follow the dynamics of the Covid-19 pandemic at Abass NDAO Hospital. This would be due to the higher risk of infection in hospitals but also to certain restrictive measures limiting travel. These results are corroborated by several authors. Effective measures must be taken to avoid the consequences of maternal mortality and the functioning of the structure. The extension of telemedicine can be a way to explore especially in times of crisis. Populations must also be committed to a paradigm shift.

This is mainly a literature review with a limit on the number of variables filled in, the study focuses exclusively on pathological pregnancies.
