Salpingectomy for Sterilization: Change in Practice in a Large Integrated Health Care System, 2011-2016.

OBJECTIVE: To evaluate the utilization rate of salpingectomy for cesarean deliveries and postpartum and interval tubal sterilization procedures. METHODS: This is a retrospective cohort study using the electronic medical record to identify women older than 18 years of age undergoing surgical sterilization from June 2011 to May 2016 in an integrated health care system. The primary objective is to describe the change in utilization rate of salpingectomy for tubal sterilization procedures over time and after a systemwide practice recommendation was issued in 2013. Rates of salpingectomy and tubal occlusion were calculated for each of the five 1-year intervals in the study. Secondary outcomes included blood loss, operating time, length of stay, readmission, and emergency department visits. RESULTS: A total of 10,741 tubal sterilization procedures were identified. There was an increase in salpingectomies from 0.4% (8/1,938; 95% CI 0.2-0.8) to 35.5% (902/2,538; 95% CI 33.7-37.4) of tubal sterilization procedures performed over the study period (test for trend, P<.001). Salpingectomy instead of tubal occlusion increased at cesarean delivery from 0.1% (1/1,141; 95% CI 0.0-0.5) to 9.2% (125/1,354; 95% CI 7.8-10.9) (test for trend, P<.001); postpartum from 0% (0/124; 95% CI 0.0-3.0) to 4.5% (9/201; 95% CI 2.4-8.3) (test for trend, P=.003); and as an interval (nonpartum) tubal sterilization procedure from 1% (7/673; 95% CI 0.5-2.1) to 78% (768/983; 95% CI 75.4-80.6) (test for trend, P<.001). Median operative minutes was increased from 52 (95% CI 51-52) to 61.5 (95% CI 57-64), from 33 (95% CI 32-34) to 50 (95% CI 35-64), and from 30 (95% CI 29-30) to 33 (95% CI 32-33), respectively, for salpingectomy compared with tubal occlusion at cesarean delivery and postpartum and interval sterilization. Median blood loss was similar for salpingectomy and tubal occlusion at cesarean delivery (660 mL; 95% CI 600-700 mL compared with 700 mL; 95% CI 680-700 mL) and interval sterilization (both 5 mL; 95% CI 5-5 mL) but was more for salpingectomy postpartum (250 mL; 95% CI 200-500 mL compared with 200 mL; 95% CI 200-200 mL). CONCLUSION: There was a significant increase in salpingectomy for sterilization from June 2011 to May 2016. In the final year of the study, salpingectomy accounted for 78% of interval laparoscopic tubal sterilization procedures and 9% of intrapartum and postpartum procedures.

Trends in use of and complications from intrauterine contraceptive devices and tubal ligation or occlusion.

BACKGROUND: Long-acting reversible contraceptives such as intrauterine devices (IUDs) are highly effective in preventing pregnancy, cost effective, and increasing in popularity. It is unclear whether changes in IUD use are associated with changes in rates of irreversible tubal sterilization. In this analysis, we evaluate changes in rates of tubal sterilization, insertion of copper or levonorgestrel (LNG) IUDs, and related complications over time. METHODS: Data were obtained from a retrospective claims database (OptumTM ClinformaticsTM Data Mart) of women aged 15 to 45 years who underwent insertion of copper or LNG IUD or tubal sterilization between 1/1/2006 and 12/31/2011. Outcomes of interest included annual rates of insertion or sterilization and annual rates of potential complications and side effects. RESULTS: The number of women included in the analysis each year ranged from 1,870,675 to 2,016,916. Between 2006 and 2011, copper IUD insertion claim rates increased from 0.18 to 0.25% and LNG IUD insertion claim rates increased from 0.63 to 1.15%, while sterilization claims decreased from 0.78 to 0.66% (P < 0.0001 for all comparisons). Increases in IUD insertion were apparent in all age groups; decreases in tubal sterilization occurred in women aged 20 to 34 years. The most common side effects and complications were amenorrhea (7.36-11.59%), heavy menstrual bleeding (4.85-15.69%), and pelvic pain (11.12-14.27%). Significant increases in claims of certain complications associated with IUD insertion or sterilization were also observed. CONCLUSION: Between 2006 and 2011, a decrease in sterilization rates accompanied an increase in IUD insertion rates, suggesting that increasing numbers of women opted for reversible methods of long-term contraception over permanent sterilization.

Obstetric Anesthesia Workforce Survey: A 30-Year Update.

BACKGROUND: Obstetric Anesthesia Workforce Surveys were conducted in 1981, 1992, and 2001, and the 10-year update was conducted in 2012. Anesthesia providers from US hospitals were surveyed to identify the methods used to provide obstetric anesthesia. Our primary hypothesis was that the provision of obstetric anesthesia services has changed in the past 10 years. METHODS: A sample of hospitals was generated based on the number of births per year and US census region. Strata were defined as follows: I ≥ 1500 annual births (n = 341), II ≥ 500 to 1499 annual births (n = 438), and III < 500 annual births (n = 414). Contact email information for the anesthesia provider in charge of obstetric services was obtained by phone call. Electronic questionnaires were sent through email. RESULTS: Administration of neuraxial (referred to as "regional" in previous surveys) labor analgesia was available 24 hours per day in all stratum I hospitals responding to the survey. Respondents across all strata reported high rates of in-house coverage, with 86.3% (95% confidence interval [CI] = 82.7%-90%) of stratum I providers reporting that they provided in-house anesthesiology services for obstetrics. The use of patient-controlled epidural analgesia in stratum I hospitals was reported to be 35% in 2001 and 77.6% (95% CI = 73.2%-82.1%) in this survey. Independent Certified Registered Nurse Anesthetists were reported to provide obstetric anesthesia services in 68% (95% CI = 57.9%-77.0%) of stratum III hospitals. Although 76% (95% CI = 71.2%-80.3%) of responding stratum I hospitals allow postpartum tubal ligations, 14% report inadequate staffing to provide anesthesia either always or at off-hours. CONCLUSIONS: Since 2001, there have been significant changes in how responding hospitals provide obstetric anesthesia care and staff the labor and delivery ward. Obstetric anesthesia surveys, updated every 10 years, continue to provide information about changes in obstetric anesthesia practice.

Trends and Disparities in Postpartum Sterilization after Cesarean Section, 2000 through 2008.

PURPOSE: Tubal sterilization patterns are influenced by factors including patient race, ethnicity, level of education, method of payment, and hospital size and affiliation. However, less is known about how these factors influence tubal sterilizations performed as secondary procedures after cesarean sections (C-sections). Thus, this study examines variations in the prevalence of postpartum tubal sterilizations after C-sections from 2000 to 2008. METHODS: We used data from the National Hospital Discharge Survey to estimate odds ratios for patient-level (race, marital status, age) and system-level (hospital size, type, region) factors on the likelihood of receiving tubal sterilization after C-section. RESULTS: A disproportionate share of postpartum tubal sterilizations after C-section was covered by Medicaid. The likelihood of undergoing sterilization was increased for Black women, women of older age, and non-single women. Additionally, they were increased in proprietary and government hospitals, smaller hospital settings, and the Southern United States. CONCLUSIONS: Our findings indicate that Black women and those with Medicaid coverage in particular were substantially more likely to undergo postpartum tubal sterilization after C-section. We also found that hospital characteristics and region were significant predictors. This adds to the growing body of evidence that suggests that tubal sterilization may be a disparity issue patterned by multiple factors and calls for greater understanding of the role of patient-, provider-, and system-level characteristics on such outcomes.

Cost and efficacy comparison of in vitro fertilization and tubal anastomosis for women after tubal ligation.

OBJECTIVE: To compare cost and efficacy of tubal anastomosis to in vitro fertilization (IVF) in women who desired fertility after a tubal ligation. DESIGN: Cost-effectiveness analysis. SETTING: Not applicable. PATIENT(S): Not applicable. INTERVENTION(S): Not applicable. MAIN OUTCOME MEASURE(S): Cost per ongoing pregnancy. RESULT(S): Cost per ongoing pregnancy for women after tubal anastomosis ranged from $16,446 to $223,482 (2014 USD), whereas IVF ranged from $32,902 to $111,679 (2014 USD). Across maternal age groups <35 and 35-40, years tubal anastomosis was more cost effective than IVF for ongoing pregnancy. Sensitivity analyses validated these findings across a wide range of ongoing pregnancy probabilities as well as costs per procedure. CONCLUSION(S): Tubal anastomosis was the most cost-effective approach for most women less than 41 years of age, whereas IVF was the most cost-effective approach for women aged ≥41 years who desired fertility after tubal ligation. A model was created that can be modified based on cost and success rates in individual clinics for improved patient counseling.

Conceptualizing risk and effectiveness: a qualitative study of women's and providers' perceptions of nonsurgical female permanent contraception.

OBJECTIVE: Novel approaches to nonsurgical permanent contraception (NSPC) for women that are low cost and require no incision or hysteroscope/surgical equipment could improve access to, and the acceptability of, permanent contraception (PC). To better understand opportunities and limitations for NSPC approaches, we examined women's and obstetrician-gynecologist (OB/GYN) providers' perceptions of NSPC in Portland, OR. STUDY DESIGN: Semistructured, qualitative interviews were conducted with 40 women recruited from outpatient clinics with purposive sampling, and a focus group was conducted with 9 OB/GYNs in academic and community practice. Transcripts were coded and inductively analyzed with a grounded theory approach. RESULTS: The majority of women identified as white (67%) or Latina (25%). They had a median age of 31.5 years, and median number of children was one. Perspectives on NSPC were closely aligned with women's general attitudes towards PC; over half were considering PC for themselves or partners in the future. Most respondents valued multiple aspects of a nonsurgical approach, with themes of minimizing recovery time, invasiveness and risk and avoiding hormonal contraception. Many assumed that NSPC would be less effective than surgery, however, and felt that a confirmation test would be necessary regardless of the failure rate. Providers welcomed efforts to expand contraceptive choice with NSPC, but would require long-term safety and efficacy data before recommending, and voiced concerns that NSPC's potential relative ease of administration could undermine the inherent seriousness of choosing PC. CONCLUSIONS: Women's and providers' perceptions of NSPC hinged on the ways in which they conceptualized risk and effectiveness. While perceptions were generally favorable, confirmation of safety and effectiveness would be required for a new approach to be accepted. IMPLICATIONS: This hypothesis-generating study elucidates women's and provider's perspectives on new methods of NSPC and contributes to understanding their perceptions of various types of risk. A technique to verify tubal occlusion would be needed for women and providers to accept NSPC.

Interest in nonsurgical female permanent contraception among men in Portland, Oregon and eastern Maharashtra, India.

OBJECTIVE: We examined the men's attitudes and perceptions toward the concept of female nonsurgical permanent contraception (NSPC) or novel approaches to permanent contraception (PC) that do not require incisions or surgical equipment/hysteroscope. STUDY DESIGN: Cross-sectional survey of married/partnered men in Portland, OR, and rural eastern Maharashtra, India. Descriptive analysis was performed. RESULTS: In India (N=150), most men (80%) anticipated that their partners would undergo PC in the future, compared to 30% in Portland (N=170). About a third (39.6% in India, 82% in Portland) reported being uncomfortable with PC for partners due to the need for surgery. Most men (85% in India, 82% in Portland) expressed a preference for a hypothetical new method of female NSPC over surgery, if safe and effective. CONCLUSION: Most men sampled in two diverse settings expressed interest in NSPC for women. IMPLICATIONS: Men's perceptions of new female contraceptive methods are important to the contraceptive development process. Men may find a safe and effective nonsurgical method of permanent female contraception more acceptable than surgical PC.

The history and current status of fallopian tube pressures - developing alternate methods for confirmation of tubal occlusion.

Permanent contraception with hysteroscopic tubal ligation is an increasingly popular choice for women around the world. However, inconveniences associated with the required confirmation test for tubal occlusion can be prohibitive. As new methods of permanent contraception are being investigated, ways of making all aspects of the procedure more accessible and comfortable for women should be considered. Means of examining tubal patency in the infertility population, such as tubal perfusion pressures measured at the time of hysterosalpingogram (HSG), provide inspiration for alternative methods of tubal occlusion confirmation after contraception. Evaluation of intrauterine pressures measured by a manometer attached to an intrauterine balloon catheter could serve as a preliminary tool for verification of tubal occlusion; higher pressures would indicate tubal occlusion and lower pressures would indicate the need for confirmatory HSG. The development and validation of this technique is ongoing and could reduce overall costs and patient burdens associated with the current tubal occlusion confirmation procedure.

Long-term risk of ectopic pregnancy varies by method of tubal sterilization: a whole-population study.

OBJECTIVE: To evaluate the risk of ectopic pregnancy (EP) associated with different methods of tubal sterilization. DESIGN: Population-based retrospective cohort study. SETTING: Hospitals in Western Australia. PATIENT(S): All women aged 18-44 years undergoing tubal sterilization between 1990 and 2010 at Western Australian hospitals (n = 44,829). INTERVENTION(S): Data on tubal sterilization were extracted from hospital records. MAIN OUTCOME MEASURE(S): Long-term risk of EP. RESULT(S): There were 89 EPs recorded during the observation period in women previously sterilized. The 10-year and 15-year cumulative probability of EP for all methods of tubal sterilization were 2.4/1,000 and 2.9/1,000 procedures, respectively. The 10-year cumulative probability of EP was 3.5 times higher in women sterilized before the age of 28 years than in those sterilized after the age of 33 years. An increased risk of EP existed in women who received laparoscopic partial salpingectomy (adjusted hazard ratio = 14.57, 95% confidence interval 3.50-60.60) and electrodestruction (adjusted hazard ratio = 5.65, 95% confidence interval 2.38-13.40), compared with those who had laparoscopic unspecified destruction of fallopian tubes. CONCLUSION(S): Women undergoing tubal sterilization at a young age are at particular risk for subsequent EP. The risk among younger women doubled between 5 and 15 years after sterilization. Laparoscopic electrodestruction and partial salpingectomy carried the highest risk of EP.

Trends in contraception use in Spanish adolescents and young adults (15 to 24 years) between 2002 and 2008.

OBJECTIVE: To assess changes in the use of contraceptive methods, and induced abortion rates, in Spanish adolescents and young adults aged 15 to 24 years, between 2002 and 2008. STUDY DESIGN: Representative samples of Spanish men and women aged 15 to 24 years were surveyed in 2002 (N = 1826) and 2008 (N = 2000). RESULTS: The rate of use of contraceptive methods increased from 61% in men and 60% in women in 2002 to 80% and 75%, respectively, in 2008. The most commonly used method was the condom (51% in 2002 and 71% in 2008), followed by the contraceptive pill (18% in 2002 and 18% in 2008). None of the adolescents and young adults surveyed used natural methods or the diaphragm, or had undergone sterilisation. The induced abortion rate increased from 9.28 to 13.48 per 1000 women in the group aged between 15 and 19 years, and from 14.37 to 21.05 per 1000 women in the group aged 20 to 24 years. CONCLUSION: Despite an increase in the use of effective birth control methods, the rates of abortion rose during the study period, which may indicate that compliance with the use of condoms is inadequate. There is an urgent need to develop educational campaigns or to design specific policies addressing contraception-related issues for young people.

Tubal sterilization trends in the United States.

OBJECTIVE: To review the rate, setting, and demographic characteristics of tubal sterilization and its current trend within contraceptive practice in the United States. DESIGN: Review of U.S. health care statistics, NCHS publications, English-language literature searched using MEDLINE and PubMed, and bibliographies of key references. RESULT(S): Total annual cases of tubal sterilization have declined from 687,000 in 1995 to 643,000 in 2006, despite a 4% population growth. Interval sterilizations decreased by 12%. Postpartum sterilizations remained stable and follow 8%-9% of all live births. Tubal sterilizations remain more common in black and Hispanic women; women with lower income, lower education, and higher parity; and among women living in the South. From 1981 to 1995, inpatient interval sterilizations fully migrated to ambulatory surgery care. CONCLUSION(S): After two decades of stable rates, there is a recent decline in sterilization. Improved access to a wide range of highly effective reversible contraceptives gives women flexibility when deciding how to manage their reproductive ability.

Unintended pregnancy influences racial disparity in tubal sterilization rates.

BACKGROUND: Minority women are more likely than white women to choose tubal sterilization as a contraceptive method. Disparities in rates of unintended pregnancy may help explain observed racial/ethnic differences in sterilization, but this association has not been investigated. OBJECTIVE: To examine the associations among race/ethnicity, unintended pregnancy, and tubal sterilization. DESIGN AND PARTICIPANTS: Cross-sectional analysis of data from a nationally representative sample of women aged 15-44 years [65.7% white, 14.8% Hispanic, and 13.9% African American (AA)] who participated in the 2002 National Survey of Family Growth. MAIN MEASURES: Race/ethnicity, history of unintended pregnancy, and tubal sterilization. A logistic regression model was used to estimate the effect of race/ethnicity on unintended pregnancy while adjusting for socio-demographic variables. A series of logistic regression models was then used to examine the role of unintended pregnancy as a confounder for the relationship between race/ethnicity and sterilization. KEY RESULTS: Overall, 40% of white, 48% of Hispanic, and 59% of AA women reported a history of unintended pregnancy. After adjusting for socio-demographic variables, AA women were more likely (OR: 2.0; 95% CI: 1.6-2.4) and Hispanic women as likely (OR: 1.0; 95% CI: 0.80-1.2) as white women to report unintended pregnancy. Sterilization was reported by 29% of women who had ever had an unintended pregnancy compared to 7% of women who reported never having an unintended pregnancy. In unadjusted analysis, AA and Hispanic women had significantly higher odds of undergoing sterilization (OR: 1.5; 95% CI: 1.3-1.9 and OR: 1.4; 95% CI: 1.2-1.7, respectively). After adjusting for unintended pregnancy, this relationship was attenuated and no longer significant (OR: 1.2; 95% CI: 0.95-1.4 for AA women and OR: 1.3; 95% CI: 1.0-1.6 for Hispanic women). CONCLUSION: Minority women, who more frequently experience unintended pregnancy, may choose tubal sterilization in response to prior experiences with an unintended pregnancy.

Trends in sterilization since the introduction of Essure hysteroscopic sterilization.

STUDY OBJECTIVE: To investigate trends in sterilization in women at the Detroit Medical Center, Michigan (DMC), since the introduction of Essure hysteroscopic sterilization. DESIGN: Retrospective study (Canadian Task Force classification II-2). SETTING: Outpatient surgery center and university teaching hospitals. PATIENTS: Women who underwent interval sterilization procedures at the DMC (Hutzel Women's Hospital, Sinai-Grace Hospital, and the Berry Center) and postpartum sterilization procedures at Hutzel Women's Hospital between January 1, 2002, and December 31, 2007. INTERVENTIONS: Permanent sterilization procedures including minilaparotomy tubal ligation, laparoscopic sterilization, Essure hysteroscopic sterilization, and postpartum tubal ligation performed at the time of cesarean section or after vaginal delivery. MEASUREMENTS AND MAIN RESULTS: In all, 5509 permanent sterilization procedures were performed in the 6 years between January 1, 2002, and December 31, 2007, at the DMC facilities analyzed: 2484 interval sterilization procedures at Hutzel Women's Hospital, Sinai-Grace Hospital, and the Berry Center, and 3025 postpartum tubal ligations at Hutzel Women's Hospital. From 2002 through 2007, the decrease in laparoscopic sterilizations from 97.9% to 48.5% of all interval sterilization procedures corresponded significantly with the increase in Essure hysteroscopic sterilizations from 0.0% to 51.3% (p <.001). Postpartum tubal ligations performed after vaginal delivery also decreased significantly during the study period from 7.9% to 3.3% of all vaginal deliveries (p <.001) while the percentage of tubal ligations performed at the time of cesarean section remained constant (p =.051). CONCLUSION: At the DMC facilities analyzed from January 1, 2002, through December 31, 2007, a significant decrease occurred in the percentage of laparoscopic sterilizations and postpartum tubal ligations performed after vaginal delivery. Of the interval sterilizations performed, the percentage of Essure hysteroscopic sterilizations increased significantly from 0.0% to 51.3% of all procedures. Since the approval of Essure hysteroscopic sterilization in November 2002, this minimally invasive method of hysteroscopic sterilization has increased in popularity at the DMC.
