Comparative Study Randomized Controlled Trial
Safety and efficacy of manual vacuum suction compared with conventional dilatation and sharp curettage and electric vacuum aspiration in surgical treatment of miscarriage: a randomized controlled trial.
BACKGROUND
The World Health Organization does not recommend dilatation and sharp curettage (D&C) for the surgical treatment of miscarriage during the first trimester because this may cause Asherman's syndrome due to endometrial damage; therefore, suction remains the primary treatment option. While manual vacuum aspiration (MVA) has been widely used since the 1990s outside Japan, the use of an MVA device (Women's MVA system) was approved in Japan in October 2015. Here, we examined the efficacy of the MVA kit in women surgically treated for miscarriage.
METHODS
This retrospective cohort study was conducted between 2014 and 2018 at the International University of Health and Welfare Hospital in Japan. Women who underwent surgical treatment for miscarriage within 12 weeks of pregnancy were identified and enrolled in the study. A total of 404 women were included who underwent the following procedures: 121 D&C, 123 electric vacuum aspiration (EVA), and 160 MVA. For each participant, the duration of surgery, amount of bleeding, amount of anesthetic used, incomplete abortion requiring repeat procedures, and intraoperative/postoperative complications were evaluated.
RESULTS
The duration of surgery was 13.7 ± 7.2, 11.2 ± 4.2, and 6.9 ± 4.3 min in the D&C, EVA, and MVA groups, respectively (p = 1.00). The amount of anesthetic used was not significantly different among all groups. Bleeding of ≥ 100 mL was confirmed in three (2.4%), one (0.8%), and one (0.6%) patient(s) in the D&C, EVA, and MVA groups, respectively (p = 0.50). Incomplete abortion was identified in three (2.4%), two (1.6%), and one (0.6%) patient(s) in the D&C, EVA, and MVA groups, respectively (p = 0.61). However, severe intraoperative/postoperative complications were not observed in any group.
CONCLUSIONS
Surgical treatment for miscarriage performed using the MVA kit has safety and efficacy similar to those of conventional methods, such as D&C and EVA.

Manual vacuum aspiration (MVA) and medical abortion were introduced to replace dilation and curettage/evacuation for incomplete abortions, and postabortion contraception was provided in 5 selected public hospitals in Pakistan. In the largest hospital, an Ipas MVA training center since 2007, MVA use reached 21% in 2008. After the International Federation of Gynecology and Obstetrics (FIGO) and UNFPA provided MVA kits, MVA use increased dramatically to 70%-90% in 2010-2013. In 2 of the remaining 4 hospitals in which the Society of Obstetricians and Gynecologists of Pakistan trained doctors in May 2012 and January 2013, the target of having 50% of women managed by MVA and medical abortion (MA) was met; however, in the third hospital only 43% were treated with MVA and MA. In the fourth hospital, where misoprostol and electric vacuum aspiration use was 64% and 9%, respectively, before training, an MVA workshop introduced the technique. Postabortion contraception was provided to 9%-29% of women, far below the target of 60%.

Review
BACKGROUND
Different surgical methods for termination of pregnancy have evolved over the years: Dilatation and curettage, power operated vacuum aspiration, manual vacuum aspiration (MVA) or hysterotomy. Local or general anaesthesia is used for all methods. Preabortion medical or mechanical cervical preparation may reduce the incidence of cervical or uterine injuries.
OBJECTIVES
To compare the safety and efficacy of different surgical methods for first trimester abortion.
SEARCH STRATEGY
The Cochrane Controlled Trials Register has been searched. A search of the reference lists of identified trials was performed. An additional MEDLINE search was done using the Internet search service Pub Med.
SELECTION CRITERIA
Randomised controlled trials comparing different surgical methods for first trimester abortion were eligible.
DATA COLLECTION AND ANALYSIS
Trials under consideration were evaluated for methodological quality and appropriateness for inclusion. Three trials were included, resulting in 2 comparisons: vacuum aspiration versus dilatation and curettage and flexible versus rigid vacuum aspiration cannula. Results are reported as odds ratio for dichotomous data and weighted mean differences for continuous data.
MAIN RESULTS
There were no reports of maternal deaths and cases of uterine perforation in the trials identified. Vacuum aspiration versus dilatation and curettage: There were no statistically significant differences for excessive blood loss, blood transfusion, febrile morbidity, incomplete or repeat uterine evacuation procedure, re-hospitalisation, post operative abdominal pain or therapeutic antibiotic use. Duration of operation was statistically significantly shorter with vacuum aspiration compared to D&C in both gestational age subgroups : < 9 weeks: weighted mean difference (WMD) -1.84 minutes, 95% confidence interval (CI) [-2.542,-1.138]; =/> 9 weeks: WMD -0.600 minutes, 95% CI [-1.166,-0.034]). Flexible versus rigid vacuum aspiration cannula: There were no statistically significant differences with regard to cervical injuries, febrile morbidity, blood transfusion, therapeutic antibiotic use, or incomplete or repeat uterine evacuation procedure.
REVIEWER'S CONCLUSIONS
The included studies do not indicate a preference of providers for one or the other method. The trials included are small and lack power to to present meaningful differences for rare outcomes between the groups. outcomes such as women's satisfaction, the need for pain relief or surgeons preference for the instrument have been inadequately addressed. No data outcomes, such as fertility after surgical abortion, are available.

Meta-Analysis
BACKGROUND
Non-tubal ectopic pregnancy is the implantation of an embryo at a site lying outside the uterine cavity or fallopian tubes. Sites include a caesarean scar, the cornua uteri, the ovary, the cervix, and the abdomen. There has been an increasing trend in the occurrence of these rare conditions, especially caesarean scar pregnancy (CSP).
OBJECTIVES
To evaluate the clinical effectiveness and safety of surgery, medical treatment, and expectant management of non-tubal ectopic pregnancy in terms of fertility outcomes and complications.
SEARCH METHODS
We searched the Cochrane Gynaecology and Fertility (CGF) Group Specialised Register of Controlled Trials, CENTRAL, MEDLINE, Embase, ClinicalTrials.gov, the World Health Organization (WHO) search portal and nine other databases to 12 December 2019. We handsearched reference lists of articles retrieved and contacted experts in the field to obtain additional data.
SELECTION CRITERIA
We included randomized controlled trials (RCTs) published in all languages that examined the effects and safety of surgery, medical treatment, and expectant management of non-tubal ectopic pregnancy.
DATA COLLECTION AND ANALYSIS
We used Cochrane standard methodological procedures. Primary outcomes were treatment success and complications.
MAIN RESULTS
We included five RCTs with 303 women, all reporting Caesarean scar pregnancy. Two compared uterine arterial embolization (UAE) or uterine arterial chemoembolization (UACE) plus methotrexate (MTX) versus systemic MTX and subsequent dilation and suction curettage; one compared UACE plus MTX versus ultrasonography-guided local MTX injection; and two compared suction curettage under hysteroscopy versus suction curettage under ultrasonography after UAE/UACE. The quality of evidence ranged from moderate to very low. The main limitations were imprecision (small sample sizes and very wide confidence intervals (CI) for most analyses), multiple comparisons with a small number of trials, and insufficient data available to assess heterogeneity. UAE/UACE versus systemic MTX prior to suction curettage Two studies reported this comparison. One compared UAE with systemic MTX and one compared UACE plus MTX versus systemic MTX, in both cases followed by a suction curettage. We are uncertain whether UAE/UACE improved success rates after initial treatment (UAE: risk ratio (RR) 1.00, 95% CI 0.90 to 1.12; 1 RCT, 72 women; low-quality evidence; UACE: RR 0.87, 95% CI 0.54 to 1.38; 1 RCT, 28 women; low-quality evidence). We are uncertain whether UAE/UACE reduced rates of complications (UAE: RR 0.47, 95% CI 0.13 to 1.75; 1 RCT, 72 women; low-quality evidence; UACE: RR 0.62, 95% CI 0.26 to 1.48; 1 RCT, 28 women; low-quality evidence). We are uncertain whether UAE/UACE reduced adverse effects (UAE: RR 1.58, 95% CI 0.41 to 6.11; 1 RCT, 72 women; low-quality evidence; UACE: RR 1.16, 95% CI 0.32 to 4.24; 1 RCT, 28 women; low-quality evidence), and it was not obvious that the types of events had similar values to participants (e.g. fever versus vomiting). Blood loss was lower in UAE/UACE groups than systemic MTX groups (UAE: mean difference (MD) -378.70 mL, 95% CI -401.43 to -355.97; 1 RCT, 72 women; moderate-quality evidence; UACE: MD -879.00 mL, 95% CI -1135.23 to -622.77; 1 RCT, 28 women; moderate-quality evidence). Data were not available on time to normalize β-human chorionic gonadotropin (β-hCG). UACE plus MTX versus ultrasonography-guided local MTX injection We are uncertain whether UACE improved success rates after initial treatment (RR 0.95, 95% CI 0.56 to 1.60; 1 RCT, 45 women; very low-quality evidence). Adverse effects: the study reported the same number of failed treatments in each arm (RR 0.88, 95% CI 0.40 to 1.92; 1 RCT, 45 women). We are uncertain whether UACE shortened the time to normalize β-hCG (MD 1.50 days, 95% CI -3.16 to 6.16; 1 RCT, 45 women; very low-quality evidence). Data were not available for complications. Suction curettage under hysteroscopy versus under ultrasonography after UAE/UACE. Two studies reported this comparison. One compared suction curettage under hysteroscopy versus under ultrasonography after UAE, and one compared these interventions after UACE. We are uncertain whether suction curettage under hysteroscopy improved success rates after initial treatment (UAE: RR 0.91, 95% CI 0.81 to 1.03; 1 RCT, 66 women; very low-quality evidence; UACE: RR 1.02, 95% CI 0.96 to 1.09; 1 RCT, 92 women; low-quality evidence). We are uncertain whether suction curettage under hysteroscopy reduced rates of complications (UAE: RR 4.00, 95% CI 0.47 to 33.91; 1 RCT, 66 women; very low-quality evidence; UACE: RR 0.18, 95% CI 0.01 to 3.72; 1 RCT, 92 women; low-quality evidence). We are uncertain whether suction curettage under hysteroscopy reduced adverse effects (UAE: RR 3.09, 95% CI 0.12 to 78.70; 1 RCT, 66 women; very low-quality evidence; UACE: not estimable; 1 RCT, 92 women; very low-quality evidence). We are uncertain whether suction curettage under hysteroscopy shortened the time to normalize β-hCG (UAE: MD 4.03 days, 95% CI -1.79 to 9.85; 1 RCT, 66 women; very low-quality evidence; UACE: MD 0.84 days, 95% CI -1.90 to 3.58; 1 RCT, 92 women; low-quality evidence). Non-tubal ectopic pregnancy other than CSP No studies reported on non-tubal ectopic pregnancies in locations other than on a caesarean scar.
AUTHORS' CONCLUSIONS
For Caesarean scar pregnancies (CSP) it is uncertain whether there is a difference in success rates, complications, or adverse events between UAE/UACE and administration of systemic MTX before suction curettage (low-quality evidence). Blood loss was lower if suction curettage is conducted after UAE/UACE than after administration of systemic MTX (moderate-quality evidence). It is uncertain whether there is a difference in treatment success rates, complications, adverse effects or time to normalize β-hCG between suction curettage under hysteroscopy and under ultrasonography (very low-quality evidence). There are no studies of non-tubal ectopic pregnancy other than CSP and RCTs for these types of pregnancy are unlikely.

Meta-Analysis Review
BACKGROUND
Miscarriage is a common complication of early pregnancy that can have both medical and psychological consequences such as depression and anxiety. The need for routine surgical evacuation with miscarriage has been questioned because of potential complications such as cervical trauma, uterine perforation, hemorrhage, or infection.
OBJECTIVES
To compare the safety and effectiveness of expectant management versus surgical treatment for early pregnancy failure.
SEARCH METHODS
We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (9 February 2012), the Cochrane Central Register of Controlled Trials (The Cochrane Library 2011, Issue 4 of 4), PubMed (2005 to 11 January 2012), POPLINE (inception to 11 January 2012), LILACS (2005 to 11 January 2012) and reference lists of retrieved studies.
SELECTION CRITERIA
Randomized trials comparing expectant care and surgical treatment (vacuum aspiration or dilation and curettage) for miscarriage were eligible for inclusion.
DATA COLLECTION AND ANALYSIS
Two review authors assessed trial quality and extracted data. We contacted study authors for additional information. For dichotomous data, we calculated the Mantel-Haenszel risk ratio (RR) with 95% confidence interval (CI). For continuous data, we computed the mean difference (MD) and 95% CI. We entered additional data such as medians into 'Other data' tables.
MAIN RESULTS
We included seven trials with 1521 participants in this review. The expectant-care group was more likely to have an incomplete miscarriage by two weeks (RR 3.98; 95% CI 2.94 to 5.38) or by six to eight weeks (RR 2.56; 95% CI 1.15 to 5.69). The need for unplanned surgical treatment was greater for the expectant-care group (RR 7.35; 95% CI 5.04 to 10.72). The mean percentage needing surgical management in the expectant-care group was 28%, while 4% of the surgical-treatment group needed additional surgery. The expectant-care group had more days of bleeding (MD 1.59; 95% CI 0.74 to 2.45). Further, more of the expectant-care group needed transfusion (RR 6.45; 95% CI 1.21 to 34.42). The mean percentage needing blood transfusion was 1.4% for expectant care compared with none for surgical management. Results were mixed for pain. Diagnosis of infection was similar for the two groups (RR 0.63; 95% CI 0.36 to 1.12), as were results for various psychological outcomes. Pregnancy data were limited. Costs were lower for the expectant-care group (MD -499.10; 95% CI -613.04 to -385.16; in UK pounds sterling).
AUTHORS' CONCLUSIONS
Expectant management led to a higher risk of incomplete miscarriage, need for unplanned (or additional) surgical emptying of the uterus, bleeding and need for transfusion. Risk of infection and psychological outcomes were similar for both groups. Costs were lower for expectant management. Given the lack of clear superiority of either approach, the woman's preference should be important in decision making. Pharmacological ('medical') management has added choices for women and their clinicians and has been examined in other reviews.

BACKGROUND
Despite the increasing trend of Postabortion Care (PAC) needs and provision, the evidence related to its cost is lacking. This study aims to review the costs of Postabortion Care (PAC) per patient at a national level.
METHODS
A systematic review of literature related to PAC cost published in 1994 - October 2020 was performed. Electronic databases such as PubMed, Medline, The Cochrane Library, CINAHL, and PsycINFO were used to search the literature. Following the title and abstract screening, reporting quality was appraised using the Consolidates Health Economic Evaluation (CHEERS) checklist. PAC costs were extrapolated into US dollars ($US) and international dollars ($I), both in 2019.
RESULTS
Twelve studies met the inclusion criteria. All studies reported direct medical cost per patient in accessing PAC, but only three of them included indirect medical cost. All studies reported either average or range of cost. In terms of range, the highest direct cost of PAC with MVA (Medical Vacuum Aspiration) services can be found in Colombia, between $US50.58-212.47, while the lowest is in Malawi ($US15.2-139.19). The highest direct cost of PAC with D&C (Dilatation and Curettage), services is in El Salvador ($US65.22-240.75), while the lowest is in Bangladesh ($US15.71-103.85). Among two studies providing average indirect cost data, Uganda with $US105.04 has the highest average indirect medical cost, while Rwanda with $US51.44 has the lowest.
CONCLUSIONS
Our review shows variability in the cost of PAC across countries. This study depicts a clearer picture of how costly it is for women to access PAC services, although it is still seemingly underestimated. When a study compared the use of UE (Uterine Evacuation) method between MVA and D&C, it is confirmed that MVA treatments tend to have lower costs and potentially reduce a significant cost. Therefore, by looking at both clinical and economic perspectives, improving and strengthening the quality and accessibility of PAC with MVA is a priority.

AIM
Endometrial biopsy is generally performed with a metal uterine curette sonde; however, recently, many types of vacuum aspirators are available, including the manual vacuum aspiration (MVA) system. We used the women's MVA system for endometrial sampling and evaluated its effectiveness in determining the presence of endometrial malignancy.
METHODS
Forty-seven samples were examined using the following procedures after measuring endometrial thickness by transvaginal ultrasonography: fractional curettage biopsy (Bx; 20 samples), total curettage under general anesthesia (T/C; 13 samples), and MVA (14 samples). The quality of the endometrial samples was classified into four types: 1-4, where 1 denoted poor and 4, good quality.
RESULTS
The mean score of the MVA group was significantly higher than that of the partial curettage biopsy group (p = 0.0065). No differences were observed between the MVA and total curettage groups (p = 1.00). When patients were divided into two groups according to endometrial thickness (<10 mm or ≥10 mm) and analyzed, both the MVA and T/C groups did not show a significant difference in their scores compared to the Bx group when the endometrial thickness was <10 mm. However, when the endometrial thickness was ≥10 mm, the MVA and T/C groups had significantly better scores than the Bx group (p = 0.0225 and p = 0.0244, respectively). Vagal reflex, as an adverse event, was observed only in two patients in the Bx group (2/20, 10%).
CONCLUSION
Considering its quality and safety, Karman-type MVA for endometrial sampling could be an alternative to fractional curettage using a metallic uterine curette sonde.

Comparative Study
BACKGROUND
A cesarean scar pregnancy is an iatrogenic consequence of a previous cesarean delivery. The gestational sac implants into a niche created by the incision of the previous cesarean delivery, and this carries a substantial risk for major maternal complications. The aim of this study was to report, analyze, and compare the effectiveness and safety of different treatments options for cesarean scar pregnancies managed in the first trimester through a registry.
OBJECTIVE
This study aimed to evaluated the ultrasound findings, disease behavior, and management of first-trimester cesarean scar pregnancies.
STUDY DESIGN
We created an international registry of cesarean scar pregnancy cases to study the ultrasound findings, disease behavior, and management of cesarean scar pregnancies. The Cesarean Scar Pregnancy Registry collects anonymized ultrasound and clinical data of individual patients with a cesarean scar pregnancy on a secure, digital information platform. Cases were uploaded by 31 participating centers across 19 countries. In this study, we only included live and failing cesarean scar pregnancies (with or without a positive fetal heart beat) that received active treatment (medical or surgical) before 12+6 weeks' gestation to evaluate the effectiveness and safety of the different management options. Patients managed expectantly were not included in this study and will be reported separately. Treatment was classified as successful if it led to a complete resolution of the pregnancy without the need for any additional medical interventions.
RESULTS
Between August 29, 2018, and February 28, 2023, we recorded 460 patients with cesarean scar pregnancies (281 live, 179 failing cesarean scar pregnancy) who fulfilled the inclusion criteria and were registered. A total of 270 of 460 (58.7%) patients were managed surgically, 123 of 460 (26.7%) patients underwent medical management, 46 of 460 (10%) patients underwent balloon management, and 21 of 460 (4.6%) patients received other, less frequently used treatment options. Suction evacuation was very effective with a success rate of 202 of 221 (91.5%; 95% confidence interval, 87.8-95.2), whereas systemic methotrexate was least effective with only 38 of 64 (59.4%; 95% confidence interval, 48.4-70.4) patients not requiring additional treatment. Overall, surgical treatment of cesarean scar pregnancies was successful in 236 of 258 (91.5%, 95% confidence interval, 88.4-94.5) patients and complications were observed in 24 of 258 patients (9.3%; 95% confidence interval, 6.6-11.9).
CONCLUSION
A cesarean scar pregnancy can be managed effectively in the first trimester of pregnancy in more than 90% of cases with either suction evacuation, balloon treatment, or surgical excision. The effectiveness of all treatment options decreases with advancing gestational age, and cesarean scar pregnancies should be treated as early as possible after confirmation of the diagnosis. Local medical treatment with potassium chloride or methotrexate is less efficient and has higher rates of complications than the other treatment options. Systemic methotrexate has a substantial risk of failing and a higher complication rate and should not be recommended as first-line treatment.

Meta-Analysis Review
BACKGROUND
The World Health Organization recommends that abortion can be provided at the lowest level of the healthcare system. Training mid-level providers, such as midwives, nurses and other non-physician providers, to conduct first trimester aspiration abortions and manage medical abortions has been proposed as a way to increase women's access to safe abortion procedures.
OBJECTIVES
To assess the safety and effectiveness of abortion procedures administered by mid-level providers compared to doctors.
SEARCH METHODS
We searched the CENTRAL Issue 7, MEDLINE and POPLINE databases for comparative studies of doctor and mid-level providers of abortion services. We searched for studies published in any language from January 1980 until 15 August 2014.
SELECTION CRITERIA
Randomised controlled trials (RCTs) (clustered or not clustered), prospective cohort studies or observational studies that compared the safety or effectiveness (or both) of any type of first trimester abortion procedure, administered by any type of mid-level provider or doctors, were eligible for inclusion in the review.
DATA COLLECTION AND ANALYSIS
Two independent review authors screened abstracts for eligibility and double-extracted data from the included studies using a pre-tested form. We meta-analysed primary outcome data using both fixed-effect and random-effects models to obtain pooled risk ratios (RR) with 95% confidence intervals (CIs). We carried out separate analyses by study design (RCT or cohort) and type of abortion procedure (medical versus surgical).
MAIN RESULTS
Eight studies involving 22,018 participants met our eligibility criteria. Five studies (n = 18,962) assessed the safety and effectiveness of surgical abortion procedures administered by mid-level providers compared to doctors. Three studies (n = 3056) assessed the safety and effectiveness of medical abortion procedures. The surgical abortion studies (one RCT and four cohort studies) were carried out in the United States, India, South Africa and Vietnam. The medical abortion studies (two RCTs and one cohort study) were carried out in India, Sweden and Nepal. The studies included women with gestational ages up to 14 weeks for surgical abortion and nine weeks for medical abortion.Risk of selection bias was considered to be low in the three RCTs, unclear in four observational studies and high in one observational study. Concealment bias was considered to be low in the three RCTs and high in all five observational studies. Although none of the eight studies performed blinding of the participants to the provider type, we considered the performance bias to be low as this is part of the intervention. Detection bias was considered to be high in all eight studies as none of the eight studies preformed blinding of the outcome assessment. Attrition bias was low in seven studies and high in one, with over 20% attrition. We considered six studies to have unclear risk of selective reporting bias as their protocols had not been published. The remaining two studies had published their protocols. Few other sources of bias were found.Based on an analysis of three cohort studies, the risk of surgical abortion failure was significantly higher when provided by mid-level providers than when procedures were administered by doctors (RR 2.25, 95% CI 1.38 to 3.68), however the quality of evidence for this outcome was deemed to be very low. For surgical abortion procedures, we found no significant differences in the risk of complications between mid-level providers and doctors (RR 0.99, 95% CI 0.17 to 5.70 from RCTs; RR 1.38, 95% CI 0.70 to 2.72 from observational studies). When we combined the data for failure and complications for surgical abortion we found no significant differences between mid-level providers and doctors in both the observational study analysis (RR 1.36, 95% CI 0.86 to 2.14) and the RCT analysis (RR 3.07, 95% CI 0.16 to 59.08). The quality of evidence of the outcome for RCT studies was considered to be low and for observational studies very low. For medical abortion procedures the risk of failure was not different for mid-level providers or doctors (RR 0.81, 95% CI 0.48 to 1.36 from RCTs; RR 1.09, 95% CI 0.63 to 1.88 from observational studies). The quality of evidence of this outcome for the RCT analysis was considered to be high, although the quality of evidence of the observational studies was considered to be very low. There were no complications reported in the three medical abortion studies.
AUTHORS' CONCLUSIONS
There was no statistically significant difference in the risk of failure for medical abortions performed by mid-level providers compared with doctors. Observational data indicate that there may be a higher risk of abortion failure for surgical abortion procedures administered by mid-level providers, but the number of studies is small and more robust data from controlled trials are needed. There were no statistically significant differences in the risk of complications for first trimester surgical abortions performed by mid-level providers compared with doctors.

Manual Vacuum Aspirators (MVA), Dilation and Curettage (D&C), and medical abortifacients (Misoprostol, Mifepristone and Divabo) are available in clinical settings that offer abortion and post-abortion care in Uganda. While these technologies imply appropriate and safe abortion care, legal and policy ambiguities impact health outcomes. In this article, we draw on an ethnography of abortion care delivery practice conducted in one district in Eastern Uganda between August 2018 and March 2019, with data from interviews and observations, both of interactions and during quality of care improvement and training meetings. We illuminate how, in the context of a financialized healthcare system and legal restrictions, the meanings and use of medical technologies and abortion care vary across different health facility types. In public health facilities, health workers become state agents in the control of women's bodies. In private health facilities, they become transgressors, who use medical technologies to help women attain termination surreptitiously. Health workers offset risks associated with any involvement in termination, such that pecuniary interests dominate their motivation. Normalized and disciplinary power enact and reproduce unsafe and risky conditions, leading to poor abortion care outcomes. We illustrate the mechanisms of domination and tactics of resistance in abortion care, and expose conditions upon which unsafe and risky outcomes are contingent.
