Risk of thromboembolism in patients with COVID-19 who are using hormonal contraception.

BACKGROUND: The novel coronavirus disease (COVID-19) has led to significant mortality and morbidity, including a high incidence of related thrombotic events. There has been concern regarding hormonal contraception use during the COVID-19 pandemic, as this is an independent risk factor for thrombosis, particularly with estrogen-containing formulations. However, higher estrogen levels may be protective against severe COVID-19 disease. Evidence for risks of hormonal contraception use during the COVID-19 pandemic is sparse. We conducted a living systematic review that will be updated as new data emerge on the risk of thromboembolism with hormonal contraception use in patients with COVID-19. OBJECTIVES: To determine if use of hormonal contraception increases risk of venous and arterial thromboembolism in women with COVID-19. To determine if use of hormonal contraception increases other markers of COVID-19 severity including hospitalization in the intensive care unit, acute respiratory distress syndrome, intubation, and mortality. A secondary objective is to maintain the currency of the evidence, using a living systematic review approach. SEARCH METHODS: ⁠⁠⁠⁠⁠⁠We searched CENTRAL, MEDLINE, Embase, CINAHL, Global Index Medicus, Global Health, and Scopus from inception on March 2023, and monitored the literature monthly. We updated the search strategies with new terms and added the database Global Index Medicus in lieu of LILACS. SELECTION CRITERIA: We included all published and ongoing studies of patients with COVID-19 comparing outcomes of those on hormonal contraception versus those not on hormonal contraception. This included case series and non-randomized studies of interventions (NRSI). DATA COLLECTION AND ANALYSIS: One review author extracted study data and this was checked by a second author. Two authors individually assessed risk of bias for the comparative studies using the ROBINS-I tool and a third helped reconcile differences. For the living systematic review, we will publish updates to our synthesis every six months. In the event that we identify a study with a more rigorous study design than the current included evidence prior to the planned six-month update, we will expedite the synthesis publication. MAIN RESULTS: We included three comparative NRSIs with 314,704 participants total and two case series describing 13 patients. The three NRSIs had serious to critical risk of bias in several domains and low study quality. Only one NRSI ascertained current use of contraceptives based on patient report; the other two used diagnostic codes within medical records to assess hormonal contraception use, but did not confirm current use nor indication for use. None of the NRSIs included thromboembolism as an outcome. Studies were not similar enough in terms of their outcomes, interventions, and study populations to combine with meta-analyses. We therefore narratively synthesized all included studies. Based on results from one NRSI, there may be little to no effect of combined hormonal contraception use on odds of mortality for COVID-19 positive patients (OR 1.00, 95% CI 0.41 to 2.40; 1 study, 18,892 participants; very low-certainty evidence). Two NRSIs examined hospitalization rates for hormonal contraception users versus non-users. Based on results from one NRSI, the odds of hospitalization for COVID-19 positive combined hormonal contraception users may be slightly decreased compared with non-users for patients with BMI under 35 kg/m2 (OR 0.79, 95% CI 0.64 to 0.97; 1 study, 295,689 participants; very low-certainty evidence). According to results of the other NRSI assessing use of any type of hormonal contraception, there may be little to no effect on hospitalization rates for COVID-19 positive individuals (OR 0.99, 95% CI 0.68 to 1.44; 1 study, 123 participants; very low-certainty evidence). We included two case series because no comparative studies directly assessed thromboembolism as an outcome. In a case series of six pediatric COVID-19 positive patients with pulmonary embolism, one (older than 15 years of age) was using combined hormonal contraception. In a second case series of seven COVID-19 positive patients with cerebral venous thrombosis, one was using oral contraceptives. One comparative study and one case series reported on intubation rates, but the evidence for both is very uncertain. In the comparative study of 123 COVID-19 positive patients (N = 44 using hormonal contraception and N = 79 not using hormonal contraception), no patients in either group required intubation. In the case series of seven individuals with cerebral venous thromboembolism, one oral contraceptive user and one non-user required intubation. AUTHORS' CONCLUSIONS: There are no comparative studies assessing risk of thromboembolism in COVID-19 patients who use hormonal contraception, which was the primary objective of this review. Very little evidence exists examining the risk of increased COVID-19 disease severity for combined hormonal contraception users compared to non-users of hormonal contraception, and the evidence that does exist is of very low certainty. The odds of hospitalization for COVID-19 positive users of combined hormonal contraceptives may be slightly decreased compared with those of hormonal contraceptive non-users, but the evidence is very uncertain as this is based on one study restricted to patients with BMI under 35 kg/m2. There may be little to no effect of combined hormonal contraception use on odds of intubation or mortality among COVID-19 positive patients, and little to no effect of using any type of hormonal contraception on odds of hospitalization and intubation for COVID-19 patients. We noted no large effect for risk of increased COVID-19 disease severity among hormonal contraception users. We specifically noted gaps in pertinent data collection regarding hormonal contraception use such as formulation, hormone doses, and duration or timing of contraceptive use. Differing estrogens may have different thrombogenic potential given differing potency, so it would be important to know if a formulation contained, for example, ethinyl estradiol versus estradiol valerate. Additionally, we downgraded several studies for risk of bias because information on the timing of contraceptive use relative to COVID-19 infection and method adherence were not ascertained. No studies reported indication for hormonal contraceptive use, which is important as individuals who use hormonal management for medical conditions like heavy menstrual bleeding might have different risk profiles compared to individuals using hormones for contraception. Future studies should focus on including pertinent confounders like age, obesity, history of prior venous thromboembolism, risk factors for venous thromboembolism, and recent pregnancy.

Risk of thromboembolism in patients with COVID-19 who are using hormonal contraception: a Cochrane systematic review.

BACKGROUND: The coronavirus disease COVID-19 is associated with an increased risk of thrombotic events. Individuals with COVID-19 using hormonal contraception could be at additional risk for thromboembolism, but evidence is sparse. METHODS: We conducted a systematic review on the risk of thromboembolism with hormonal contraception use in women aged 15-51 years with COVID-19. We searched multiple databases through March 2022, including all studies comparing outcomes of patients with COVID-19 using or not using hormonal contraception. We applied standard risk of bias tools to evaluate studies and GRADE methodology to assess certainty of evidence. Our primary outcomes were venous and arterial thromboembolism. Secondary outcomes included hospitalisation, acute respiratory distress syndrome, intubation, and mortality. RESULTS: Of 2119 studies screened, three comparative non-randomised studies of interventions (NRSIs) and two case series met the inclusion criteria. All studies had serious to critical risk of bias and low study quality. Overall, there may be little to no effect of combined hormonal contraception (CHC) use on odds of mortality for COVID-19-positive patients (OR 1.0, 95% CI 0.41 to 2.4). The odds of hospitalisation for COVID-19-positive CHC users may be slightly decreased compared with non-users for patients with body mass index <35 kg/m2 (OR 0.79, 95% CI 0.64 to 0.97). Use of any type of hormonal contraception may have little to no effect on hospitalisation rates for COVID-19-positive individuals (OR 0.99, 95% CI 0.68 to 1.44). CONCLUSIONS: Not enough evidence exists to draw conclusions regarding risk of thromboembolism in patients with COVID-19 using hormonal contraception. Evidence suggests there may be little to no or slightly decreased odds of hospitalisation, and little to no effect on odds of mortality for hormonal contraception users versus non-users with COVID-19.

Risk of thromboembolism in patients with COVID‐19 who are using hormonal contraception

Objectives This is a protocol for a Cochrane Review (intervention). The objectives are as follows: To determine if use of hormonal contraception increases risk of venous and arterial thromboembolism in women with COVID‐19. A secondary objective is to maintain the currency of the evidence, using a living systematic review approach.

Special ambulatory gynecologic considerations in the era of coronavirus disease 2019 (COVID-19) and implications for future practice.

The coronavirus disease 2019 pandemic has altered medical practice in unprecedented ways. Although much of the emphasis in obstetrics and gynecology to date has been on the as yet uncertain effects of coronavirus disease 2019 in pregnancy and on changes to surgical management, the pandemic has broad implications for ambulatory gynecologic care. In this article, we review important ambulatory gynecologic topics such as safety and mental health, reproductive life planning, sexually transmitted infections, and routine screening for breast and cervical cancer. For each topic, we review how care may be modified during the pandemic, provide recommendations when possible on how to ensure continued access to comprehensive healthcare at this time, and discuss ways that future practice may change. Social distancing requirements may place patients at higher risk for intimate partner violence and mental health concerns, threaten continued access to contraception and abortion services, affect prepregnancy planning, interrupt routine screening for breast and cervical cancer, increase risk of sexually transmitted infection acquisition and decrease access to treatment, and exacerbate already underlying racial and minority disparities in care and health outcomes. We advocate for increased use of telemedicine services with increased screening for intimate partner violence and depression using validated questionnaires. Appointments for long-acting contraceptive insertions can be prioritized. Easier access to patient-controlled injectable contraception and pharmacist-provided hormonal contraception can be facilitated. Reproductive healthcare access can be ensured through reducing needs for ultrasonography and laboratory testing for certain eligible patients desiring abortion and conducting phone follow-up for medication abortions. Priority for in-person appointments should be given to patients with sexually transmitted infection symptoms, particularly if at risk for complications, while also offering expedited partner therapy. Although routine mammography screening and cervical cancer screening may be safely delayed, we discuss society guideline recommendations for higher-risk populations. There may be an increasing role for patient-collected human papillomavirus self-samples using new cervical cancer screening guidelines that can be expanded considering the pandemic situation. Although the pandemic has strained our healthcare system, it also affords ambulatory clinicians with opportunities to expand care to vulnerable populations in ways that were previously underutilized to improve health equity.
