Surveillance in a time of changing health care practices: estimating ectopic pregnancy incidence in the United States.

OBJECTIVES: Ectopic pregnancy is a common condition with significant health consequences; complications are a major cause of maternal mortality in the United States. Accurate ascertainment of the number of ectopic pregnancies occurring in the United States has been dramatically affected by changing medical practices, causing estimates based on hospital data to be falsely low. This study was performed to identify nationally representative data on ectopic pregnancies and determine overlap of these data, to calculate the annual weighted number of ectopic pregnancies and confidence intervals for these estimates, and to determine barriers to estimation of ectopic pregnancy incidence. METHODS: To assess whether a national estimate of the incidence of ectopic pregnancy could be calculated, we analyzed 1992-99 data from the six nationally representative data sets that include information on ectopic pregnancy. We examined relevant data in each data set and assessed whether any combination of data sets could be used to estimate ectopic pregnancy incidence. We calculated weighted estimates and 95% confidence intervals for hospitalizations, outpatient surgeries, outpatient medical procedures, and physician visits for and self-reports of ectopic pregnancy. RESULTS: Small sample sizes severely limited calculation of estimates of ectopic pregnancy. Data needed for assessing multiple counting was not available consistently. The likelihood of multiple counting of cases was substantial when data set counts were combined. CONCLUSIONS: A reliable incidence rate for ectopic pregnancy in the United States could not be estimated from existing nationally representative data sources. Major advances in diagnosis and treatment of ectopic pregnancy have affected surveillance in two ways: inpatient hospital treatment of ectopic pregnancy has decreased, and multiple health care visits for a single ectopic pregnancy have increased. Alternate means of surveillance are needed to improve understanding of risk factors and trends for ectopic pregnancy, and we recommend examination of the databases of public and private insurance systems and managed care systems. Similar alternate means of surveillance may be needed for other health conditions with comparable changes in management of care.

[Analysis of risk factors for ectopic pregnancy in own material in the years 1993-2002].

UNLABELLED: The ectopic pregnancy is still a life-threatening condition. The risk factors for ectopic pregnancy are divided into four groups: 1) mechanic factors, 2) tubal dysfunction, 3) assisted reproductive techniques (ART) and 4) hormonal factors. MATERIAL AND METHODS: On basis of the analysis of medical documentation we determined the risk factors for ectopic pregnancy in 214 patients (aged 18-44, mean 32 +/- 9 years) hospitalized in Department of Reproductive Medicine and Gynecology of Pomeranian Medical University between 1993 and 2002. The control group composed 215 patients admitted to the hospital outpatient clinic in the years 1993-2002. RESULTS: The risk factors for ectopic pregnancy evaluated in each group of patients were: history of adnexitis, surgical procedures (appendectomy, tubal microsurgery, ovarian cystectomy, adnexectomy, myomectomy, cesarean section, previous conservative surgical treatment of ectopic pregnancy, salpingectomy), appendicitis complicated by peritonitis, endometriosis, conservative treatment of ectopic pregnancy, insertion of IUD, ovarian induction or IVF procedure, uterine defects and smoking. In the examined group 104 patients had a history of surgery (48.5%) compare to 40 patients in the control group (18.6%). Difference between groups is significant p = 0,034. In 40 cases out of 104 (18.6%) surgical operations were done two and more times. Statistics proves that surgical procedures in the past occurred significantly more frequently in the studied than in control group. The most frequent operations were: conservative surgical treatment of ectopic pregnancy (p = 0.000), tubal microsurgery (p = 0.0016), ovarian cystectomy (p = 0.013) and salpingectomy (p = 0.047). Appendectomies or myomectomies in the past did not increase the risk of ectopic pregnancy. Additionally, in the examined group there were more cases of MTX (Methotrexate) therapy applied in the past because of ectopic pregnancy (p = 0.000), more smoking (p = 0.0001) and more adnexitis in the past (p = 0.013). Treated endometriosis in the past, artificial reproductive techniques (ART), peritonitis, IUD application and uterine defects were no important risk factors for ectopic pregnancy. CONCLUSIONS: The main risk factors for ectopic pregnancy are: history of surgical procedures, especially conservative surgical treatment of ectopic pregnancy and tubal microsurgery. Appendectomy or myomectomy do not increase this risk. The other important risk factors for ectopic pregnancy are: conservative treatment of ectopic pregnancy in the past and smoking. Adnexitis is another risk factor for ectopic pregnancy.

Surveillance for ectopic pregnancy--United States, 1970-1989.

PROBLEM/CONDITION: From 1970 through 1989, hospitalizations for ectopic pregnancy have increased in the United States; the number of cases has increased fivefold, from 17,800 to 88,400. REPORTING PERIOD COVERED: 1970-1989. DESCRIPTION OF SYSTEM: Reported ectopic pregnancies were estimated from data collected by CDC's National Center for Health Statistics (NCHS) as part of the ongoing National Hospital Discharge Survey. Data from responding hospitals were weighted to represent national estimates. The number of deaths resulting from ectopic pregnancy was based on U.S. vital statistics collected by NCHS. Denominators for calculating ectopic pregnancy rates were the total number of reported pregnancies, which includes live births, legal induced abortions, and ectopic pregnancies. Data for live births were obtained from NCHS natality statistics and data for legal induced abortions from CDC's Division of Reproductive Health. RESULTS: From 1970 through 1989, more than one million ectopic pregnancies were estimated to have occurred among women in the United States; the rate increased by almost fourfold, from 4.5 to 16.0 ectopic pregnancies per 1,000 reported pregnancies. Although ectopic pregnancies accounted for < 2% of all reported pregnancies during this period, complications of this condition were associated with approximately 13% of all pregnancy-related deaths. During this period, the risk of death associated with ectopic pregnancy decreased by 90%: the case-fatality rate declined from 35.5 deaths per 10,000 ectopic pregnancies in 1970 to 3.8 in 1989. The risks of ectopic pregnancy and death from its complications were consistently higher for blacks and other racial/ethnic minorities than for whites throughout the period. INTERPRETATION: Although the general trend has been for the numbers and rates of ectopic pregnancy to increase over the 20-year period, the variability of the data does not permit meaningful conclusions to be made about year-to-year changes in the estimates of ectopic pregnancies, especially for the years 1988 and 1989. ACTIONS TAKEN: These findings indicate the need to characterize behaviors and risk factors that may respond to preventive interventions. Until these risks factors are better characterized, early detection and appropriate management of ectopic pregnancies will remain the most effective means of reducing the morbidity and mortality associated with this condition.

Ectopic pregnancy versus corpus luteum cyst revisited: best Doppler predictors.

OBJECTIVE: To determine the best Doppler values for differentiating ectopic pregnancy from a corpus luteum cyst of pregnancy. METHODS: This was a prospective study of 80 consecutive patients with the diagnosis of ectopic pregnancy. All ectopic pregnancies were diagnosed on the basis of the presence of an extra-ovarian adnexal mass on sonography and were confirmed surgically. The last menstrual period ranged from 4 to 11 weeks (mean, 6.3 weeks), and the maximal ectopic pregnancy diameter ranged from 0.7 to 5.5 cm (mean, 2.5 cm). Seventy-six ectopic pregnancies showed color vascularity, and 40 showed corpus luteum cysts with vascular walls. The highest peak systolic velocity and the lowest resistive index of the vascular ectopic pregnancies were compared with the corresponding values in the vascular corpus luteum cysts. RESULTS: The mean peak systolic velocity of the ectopic pregnancies was 35.4 cm/s compared with 28.4 cm/s in corpus luteum cysts, with no significant statistical difference (P = .1). The resistive index of the ectopic pregnancies ranged from 0.15 to 1.6 (mean +/- SD, 0.61 +/- 0.24) compared with 0.39 to 0.7 (mean, 0.52 +/- 0.10) in corpus luteum cysts, with a significant statistical difference (P = .003). In this cohort, a resistive index of less than 0.39 had a specificity of 100% and a positive predictive value of 100% for diagnosing ectopic pregnancy but was present in only 15% (confidence interval, 7%-23%) of ectopic pregnancies. A resistive index of greater than 0.7 had a specificity of 100% and a positive predictive value of 100% for diagnosing ectopic pregnancy and was present in 31% (confidence interval, 21%-41%) of ectopic pregnancies. CONCLUSIONS: Both low and high resistive indices discriminate ectopic pregnancy from a corpus luteum cyst.

Diagnosis of ectopic pregnancy--why we need a protocol.

OBJECTIVE: To audit the management after instituting a screening programme for ectopic pregnancy in an institution with a protocol utilising ultrasound examination and serial human chorionic gonadotropin (hCG) and to examine the risk of missed diagnosis with deviation from the protocol. MATERIAL AND METHOD: A retrospective analysis of the management of 145 symptomatic patients in early pregnancies without intrauterine gestational sacs from ultrasound examinations, during the period April to June 1994 in Kandang Kerbau Hospital. Patients underwent serial hCG tests over 48 hours with or without repeat ultrasound scans before definitive treatment unless clinical indications for emergency surgery was necessary. RESULTS: There were 35 ectopic pregnancies (24%), 16 were viable intrauterine pregnancies (11%), 87 were non-viable pregnancies (60%) and 7 were of unknown outcome. There were much practice deviations from the protocol. Forty-four percent (64 cases) of the management decisions were made based on the initial clinical and ultrasound findings, and another 14% (21 cases) after a repeat assessment within the next day by either a repeat scan or serial serum hCG over one day. Among them, two of the 29 operated for suspected ectopic pregnancy were not ectopic (7%) and two of the 56 thought not to be ectopic, turned out to be ectopic (4%) (p < 10(-8)). Six percent (8 cases) defaulted after the initial assessments and one of them was found to be ectopic subsequently. Thirty percent (43 cases) adhered to the protocol. They had serial serum hCG done over two days. Seven of them requiring further repeats of serial serum hCG before management decisions were made. Four patients who were operated on were confirmed ectopic and 39 patients not operated on were not ectopic. Three percent (5 cases) were managed by serial hCG over 3 to 5 days and another 3% (4 cases) by repeating scan over one to two weeks without serial hCG. None of these was ectopic. The percentage change of hCG levels over two days gave indications of the likely diagnosis. CONCLUSION: Adhering to a protocol utilising the principle of ultrasound scan, serial hCGs and selective repeat ultrasound scans are highly recommended for the diagnosis of ectopic pregnancy. Any deviation from protocol is dangerous, with a 4% risk of missing an ectopic and a 7% risk of unnecessary operation for suspected ectopic pregnancy.

Radiofrequency catheter ablation for management of symptomatic ventricular ectopic activity.

OBJECTIVES: This study assessed the useful role of intracardiac mapping and radiofrequency catheter ablation in eliminating drug-refractory monomorphic ventricular ectopic beats in severely symptomatic patients. BACKGROUND: Ventricular ectopic activity is commonly encountered in clinical practice. Usually, it is not associated with life-threatening consequences in the absence of significant structural heart disease. However, frequent ventricular ectopic beats can be extremely symptomatic and even incapacitating in some patients. Currently, reassurance and pharmacologic therapy are the mainstays of treatment. There has been little information on the use of catheter ablation in such patients. METHODS: Ten patients with frequent and severely symptomatic monomorphic ventricular ectopic beats were selected from three tertiary care centers. The mean frequency +/- SD of ventricular ectopic activity was 1,065 +/- 631 beats/h (range 280 to 2,094) as documented by baseline 24-h ambulatory electrocardiographic (ECG) monitoring. No other spontaneous arrhythmias were documented. These patients had previously been unable to tolerate or had been unsuccessfully treated with a mean of 5 +/- 3 antiarrhythmic drugs. The site of origin of ventricular ectopic activity was accurately mapped by using earliest endocardial activation time during ectopic activity or pace mapping, or both. RESULTS: During electrophysiologic study, no patient had inducible ventricular tachycardia. The ectopic focus was located in the right ventricular outflow tract in nine patients and in the left ventricular posteroseptal region in one patient. Frequent ventricular ectopic beats were successfully eliminated by catheter-delivered radiofrequency energy in all 10 patients. The mean number of radiofrequency applications was 2.6 +/- 1.3 (range 1 to 5). No complications were encountered. During a mean follow-up period of 10 +/- 4 months, no patient had a recurrence of symptomatic ectopic activity, and 24-h ambulatory ECG monitoring showed that the frequency of ventricular ectopic activity was 0 beat/h in seven patients, 1 beat/h in two patients and 2 beats/h in one patient. CONCLUSIONS: Radiofrequency catheter ablation can be successfully used to eliminate monomorphic ventricular ectopic activity. It may therefore be a reasonable alternative for the treatment of severely symptomatic, drug-resistant monomorphic ventricular ectopic activity in patients without significant structural heart disease.

Comparison of multidose and single-dose methotrexate protocols for the treatment of ectopic pregnancy.

OBJECTIVE: The purpose of this study was to compare success rates of 643 patients who had ectopic pregnancy from the same database who were treated with multidose or single-dose methotrexate protocols. STUDY DESIGN: We compared demographics, gestational age, serum human chorionic gonadotropin, progesterone levels, ectopic sac size and volume, overall ectopic mass size and volume, ectopic cardiac activity, history of ectopic pregnancy, number of treatment days, methotrexate doses, and outcome in consecutive patients with ectopic pregnancy who were treated with methotrexate. RESULTS: Success rates were comparable between patients with multidose and single-dose therapy (95% vs 90%, respectively) as were human chorionic gonadotropin and progesterone levels, history of ectopic pregnancy (21.4% vs 21.7%, respectively), number of treatment days, gestational age, ectopic size, ectopic volume, and ectopic mass volume. Patients who received single-dose therapy were significantly heavier (146 vs 159 pounds), had greater ectopic cardiac activity (3.1% vs 10.3%), and received fewer methotrexate doses. CONCLUSION: This study suggests single-dose methotrexate therapy is as effective as multidose methotrexate therapy for the treatment of ectopic pregnancy.

Epidemiology of repeat ectopic pregnancy: a population-based prospective cohort study.

OBJECTIVE: To study infectious pathology at index ectopic pregnancy and to determine what other factors predispose a woman to repeat ectopic pregnancy. METHODS: All women (n = 697) with their first (index) ectopic pregnancy histologically verified between January 1, 1978, and December 31,1993, at the only two hospitals in one Norwegian county were eligible. Included were permanent residents of the county who were 37 years of age or younger and who had not had tubal surgery before the index pregnancy. When the study closed on November 1, 1994, the participants had been observed prospectively for fertility events from approximately 1 to 17 years. Included in the final analyses were 353 women who had from one to five natural conceptions, for a total of 555 pregnancies. Chi-square test was used in univariate analysis, and the generalized estimating equations approach was used to analyze correlated responses and covariates that changed over time. RESULTS: Pregnancy order is the stronger correlate of subsequent ectopic pregnancy. The frequency of repeat ectopic pregnancy decreased by one-third for each pregnancy from the first to the third pregnancy. The odds of having another ectopic pregnancy were nearly three times higher for women with a diagnosis of infectious pathology than for women who had no infectious pathology. Other correlates of repeat ectopic pregnancy include age 24 years or younger at first ectopic pregnancy, history of repeat ectopic pregnancy, initiation of infertility work-up, and conception with an intrauterine device at index pregnancy. Method of surgery was not associated with repeat ectopic pregnancy. CONCLUSION: The most crucial reproductive event after first ectopic pregnancy is the first event to occur. Women who have experienced two ectopic pregnancies should be considered candidates for assisted reproduction.
