Short-acting and Long-acting Opioids Utilization among Women Diagnosed with Endometriosis in the United States: A Population-based Claims Study.

STUDY OBJECTIVE: To determine the prevalence and pattern of opioid use in endometriosis and the characteristics of patients prescribed an opioid using medical insurance claims data. DESIGN: We performed a retrospective cohort analysis of data from the Truven MarketScan Commercial database for the period of January 1, 2011 to December 31, 2016. SETTING: The Truven database includes inpatient, outpatient, and prescription claims covering more than 115 million unique individuals and over 36 million inpatient hospital discharges across multiple payer types and all 50 states. PATIENTS: Women with endometriosis were defined as those with 1 inpatient or 2 outpatient codes for endometriosis. INTERVENTIONS: No interventions were assigned. Women who filled an opioid prescription within 12 months of diagnosis were placed in the opioid cohort and women who did not fill an opioid prescription were placed in the nonopioid cohort. MEASUREMENTS AND MAIN RESULTS: Baseline characteristics were evaluated 12 months preindex (date of the first diagnosis) and opioid use was assessed for 12 months after the index date. The dataset included 58 472 women with endometriosis. Of these, 61.7% filled an opioid prescription during the study period. More than 95% filled prescriptions for short-acting opioids (SAOs) only, 4.1% filled prescriptions for both SAOs and extended-release/long-acting opioids (LAOs), and 0.6% filled prescriptions for LAOs only. Patients who filled an opioid prescription had higher baseline comorbidities (especially gynecologic and chronic pain comorbidities) and endometriosis-related medication use compared with patients who did not fill an opioid prescription during the study period. Patients who filled both LAO and SAO prescriptions had the highest total days' supply of opioids, the proportion of days covered by prescriptions, and morphine equivalent daily dose. These patients also had the highest proportions of opioid switching and dose augmentation. Statistical trends in data were not substantially altered when analyses excluded patients with chronic pain comorbidities or surgical opioid prescriptions. CONCLUSION: Although opioids are not a recommended treatment for endometriosis, more than half of our cohort filled an opioid prescription within 1 year after a first recorded diagnosis of endometriosis. Patients who filled an opioid prescription tended to use more endometriosis-related medications and have a higher comorbidity burden. Additional research is necessary to better understand the reasons and outcomes associated with opioid utilization in endometriosis and to determine if there is a more effective pain management treatment plan for patients taking opioids.

Hospital-Associated Cost of Endometriosis in Canada: A Population-Based Study.

STUDY OBJECTIVE: To describe the hospital-associated cost of endometriosis in Canada from April 2008 to March 2013. DESIGN: Population-based descriptive study. SETTING: Canada, with the exception of the province of Quebec. PATIENTS: All women aged 15 to 59 years discharged with endometriosis between April 2008 and March 2013. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Over 5 years, 47 021 women were admitted for endometriosis, resulting in a total hospital cost of Canadian dollars (CaD) $152.21 million (US dollars [US $] 147.79 million) and per-case cost of CaD $3237 (US $3143). Uterine endometriosis accounted for 28.29% of cases, ovarian endometriosis 27.44%, and other endometriosis 44.27%. Cost for uterine endometriosis was the highest at CaD $4137 (US $4017) per case, followed by ovarian endometriosis (CaD $3506; US $3404) and other endometriosis (CaD $2495; US $2422). The highest number of cases were in the groups aged 35 to 39 years (20.77%) and 40 to 44 years (20.44%). Hysterectomy accounted for 29.57% of surgical procedures. Encounters with hysterectomy were the costliest at CaD $5062 (US $4915) per case, followed by the ones with other surgical procedures at CaD $2477 (US $2405) per case, and admissions with no surgical procedure at CaD $2164 (US $2101) per case. CONCLUSION: The hospital cost associated with endometriosis was approximately CaD $30 million (US $29.56 million) per year, whereas uterine endometriosis, hysterectomy, and older age were found to have a higher average cost per case. Although this study focuses specifically on hospital admission and does not account for outpatient costs or indirect costs, it nonetheless highlights the economic burden of this debilitating disease on Canadian society during the study period.

Changing trends in the preference of health care facility and reasons for hysterectomy in India.

Many community-based studies from India have pointed out a sudden increase in the number of hysterectomy performed in the past few years. Using the data from the fourth round of National Family Health Survey (NFHS-4), we have attempted to examine the changing trends in the preference of health care facilities and reasons for hysterectomy in India. After analyzing the data, we have found that over the years, women are moving toward private health care providers for hysterectomy, and excessive menstrual bleeding is one of the most common reasons among them. A substantially higher proportion of hysterectomy in private health care facilities over the public raises the question of its necessity.

Patterns of hysterectomy in India: a national and state-level analysis of the Fourth National Family Health Survey (2015-2016).

OBJECTIVE: The National Family Health Survey-4 in India provided the first nationally representative estimates of hysterectomy among women aged 15-49. This paper aims to examine the national and state-level age-specific prevalence of hysterectomy, individual and household level factors associated with the procedure, and state-level indicators that may explain variation across states. DESIGN: Cross-sectional, nationally representative household survey. SETTING: National Family Health Survey was conducted across all Indian states and union territories between 2015 and 2016. POPULATION: The survey covered 699 686 women between the ages of 15 and 49 years. METHODS: Descriptive analyses and multivariate logistic regression. MAIN OUTCOME MEASURES: Women who reported ever having a hysterectomy and age at hysterectomy. RESULTS: Age-specific prevalence of hysterectomy was 0.36% (0.33,0.39) among women aged 15-29; 3.59% (3.45,3.74) among women aged 30-39; and 9.20% (8.94,9.46) among women 40-49 years. There was considerable variation in prevalence by state. Four states reported age-specific prevalence similar to high-income settings. Approximately two-thirds of hysterectomies were conducted in private facilities, with similar patterns across age groups. At the national level, higher age and parity (at least two children); not having had formal schooling; rural residence (adjusted odds ratio [AOR] 1.36; 95% CI 1.27,1.45; P < 0.01) and higher wealth status were associated with higher odds of hysterectomy. Previously sterilised women had lower odds (AOR 0.64; 95% CI 0.61,0,68; P < 0.01) of reporting hysterectomy. Exploratory analyses suggest state-level factors associated with prevalence of hysterectomy include caesarean section, female illiteracy, and women's employment. CONCLUSIONS: Hysterectomy patterns among women aged 15-49 in India indicate the critical need to ensure treatment options for gynaecological morbidity and to address hysterectomy among young women in particular. FUNDING: This study was part of the RASTA initiative of the Population Council's India country office under the Evidence Project supported by USAID. TWEETABLE ABSTRACT: Hysterectomy patterns in India highlight the need for alternatives to treat gynaecological morbidity among younger women.

Assessment of the optimal age for a preventive ultrasonographic screening of the uterine health in bitches.

Studies about prevalence of uterine pathologies in bitches are scarce. Although correlation between age and uterine disorders was documented, the most suitable age for a preventive sonographic screening has not been proposed yet. Present study aimed to estimate the eligible age for an ultrasonographic screening of uterine abnormalities in dogs. Data regarding ultrasound examination and clinical records of non-pregnant intact females were retrospectively analysed. The age of each bitch was expressed as age ratio (actual/maximum age expected for the respective breed). The cut-off age ratio was determined by a ROC curve for overall uterine abnormalities. Frequencies of different abnormalities below and over the cut-off derived from the ROC curve were calculated and statistically analysed by chi-Square and OR. Prevalence of three categories of ultrasonographic findings was as follows: cystic endometrial hyperplasia (CEH) 18%; uterine collections (UC) 10.5%; masses (M) 1.3%. By the cut-off age ratio (0.325), derived by ROC curve (AUC = 0.91; SP 84.23%; SE 79.2%; PPV 83.4%; NPV 80%), 228 cases were divided into two subgroups: bitches over (exposed group: n.83) and below cut-off (control group: n.145). All abnormalities resulted more frequent in exposed group: OR was 24.96 (p < 0.0001: 71.1% over vs. 9% below cut-off) for overall abnormalities; 13.68 (p < 0.0001: 40.9% vs. 4.8%) for CEH; 6.13 (p < 0.002: 21.7% vs. 4.1%) for UC; 12.65 (p = 0.09: 3.6% vs. 0%) for M. Cystic endometrial hyperplasia represents the most common finding in adult bitches, followed by UC. A preventive sonographic screening for uterine abnormalities should start from 33% of expected longevity to preventively select animals requiring further evaluations.

Decreasing trend of hysterectomy in Taiwan: A population-based study, 1997-2010.

OBJECTIVE: Gynecologists in Taiwan are lacking a comprehensive picture of the changes in clinical practice and indications of hysterectomy over a long period of time. The aims of this study were to examine the national trends in the utilization of hysterectomy and to explore changes in its utilization rate over a 14-year period from 1997 to 2010. MATERIALS AND METHODS: We conducted a population-based trend analysis using the claims data from the Taiwan's National Health Insurance program. RESULTS: We identified a total of 341,993 women aged 20 years or older who underwent hysterectomy between 1997 and 2010. The total number of hysterectomies increased from 22,961 in 1997 to 27,757 cases in 1999, followed by a decline to 22,351 in 2010. Overall, 5406 fewer hysterectomies (-19.5%) were performed in 2010 when compared with those performed in 1999. The number of hysterectomies performed decreased from 1997 to 2010 for precancerous lesions (-55.6%), chronic pelvic pain (-35.2%), uterine leiomyoma (-13.1%), and uterine prolapse (-7.2%). However, the utilization of hysterectomy increased for endometriosis (+76.3%) and gynecologic cancer (+22.7%) during the same time frame. CONCLUSION: The clinical utilization and primary indications of hysterectomy changed substantially in Taiwan from 1997 to 2010. The continued monitoring of changes in hysterectomy rates will be critical for understanding the appropriate indications for hysterectomy and oophorectomy, the emergence of alternative managements for uterine disorders, and future trends in women's reproductive health.

[The assessment of the dependence between antigen CA 125 and nicotinism in patients with benign ovarian tumors including endometrial cysts]. / Ocena zaleznosci poziomu antygenu Ca 125 od nikotynizmu u pacjentek z lagodnymi guzami jajników, w tym z torbielami endometrialnymi.

UNLABELLED: Cancer antigen CA-125 is a marker that is primarily used to differentiate benign from malignant tumors as well as to monitor response to ovarian cancer treatment. Taken as a separate marker, it displays low sensitivity and specificity in ovarian cancer diagnosis; however, in combination with other markers it may be successfully applied especially in postmenopausal women. Elevated CA-125 levels in blood serum indicate cancerous as well as non-cancerous diseases. Research aiming to determine environmental factors that may have influence on antigen CA-125 level, and thus on the assessment of this marker's application in gynecological and oncological diseases continues. OBJECTIVES: the aim of the present research is an attempt to estimate the influence of nicotinism on antigen CA-125 in blood serum in patients with diagnosed benign ovarian tumors including endometrial cysts. MATERIAL AND METHODS: 174 women aged 16-85 years with diagnosed benign ovarian tumor were qualified for the study. In all patients level of antigen CA-125 in blood serum was assessed preoperatively and nicotinism history was taken. Also transvaginal ultrasound was performed to obtain preliminary diagnosis. Smoking and non-smoking patients were classified into two groups, namely of those with histopathologically confirmed cysts of endometrial type and those with non-endometrial benign ovarian tumors. RESULTS: statistical analysis did not prove any dependence between the CS-125 antigen level and nicotinism in any of these groups. Also additional analysis with division into premenopausal and postmenopausal patients did not determine any statistically significant dependence. CONCLUSION: Nicotinism does not significantly influence the CA-125 antigen level in patients with benign However, the connection between the addiction severity and its influence on antigen CA-125 in blood serum cannot be excluded. ovarian tumors or endometrial cysts.

The frequency and clinical significance of intra-amniotic inflammation in women with preterm uterine contractility but without cervical change: do the diagnostic criteria for preterm labor need to be changed?

OBJECTIVE: The objective of this study was to determine the frequency and clinical significance of intra-amniotic inflammation in patients with preterm increased uterine contractility with intact membranes but without cervical change. METHODS: Amniocentesis was performed in 132 patients with regular uterine contractions and intact membranes without cervical change. Amniotic fluid was cultured for bacteria and mycoplasmas and assayed for matrix metalloproteinase-8 (MMP-8). Intra-amniotic inflammation was defined as an elevated amniotic fluid MMP-8 concentration (>23 ng/mL). RESULTS: (1) Intra-amniotic inflammation was present in 12.1% (16/132); (2) Culture-proven intra-amniotic infection was diagnosed in 3% (4/132) of patients without demonstrable cervical change on admission or during the period of observation; and (3) Patients with intra-amniotic inflammation had significantly higher rates of preterm delivery and adverse outcomes, and shorter amniocentesis-to-delivery intervals than those without intra-amniotic inflammation (P < 0.05 for each). Adverse outcomes included chorioamnionitis, funisitis, and neonatal death. CONCLUSION: Intra-amniotic inflammation was present in 12% of patients with regular uterine contractions without cervical change, while culture-proven intra-amniotic infection was present in 3%. The presence of intra-amniotic inflammation was a significant risk factor for adverse neonatal outcomes. These observations question whether cervical changes should be required for the diagnosis of preterm labor, because patients without modifications in cervical status on admission or during a period of observation are at risk for adverse pregnancy outcomes.

Hysterectomy in Germany: a DRG-based nationwide analysis, 2005-2006.

BACKGROUND: Hysterectomy is among the more common surgical procedures in gynecology. The aim of this study was to calculate population-wide rates of hysterectomy across Germany and to obtain information on the different modalities of hysterectomy currently performed in German hospitals. This was done on the basis of nationwide DRG statistics (DRG = diagnosis-related groups) covering the years 2005-2006. METHODS: We analyzed the nationwide DRG statistics for 2005 and 2006, in which we found 305 015 hysterectomies. Based on these data we calculated hysterectomy rates for the female population. We determined the indications for each hysterectomy with an algorithm based on the ICD-10 codes, and we categorized the operations on the basis of their OPS codes (OPS = Operationen- und Prozedurenschlüssel [Classification of Operations and Procedures]). RESULTS: The overall rate of hysterectomy in Germany was 362 per 100 000 person-years. 55% of hysterectomies for benign diseases of the female genital tract were performed transvaginally. Bilateral ovariectomy was performed concomitantly in 23% of all hysterectomies, while 4% of all hysterectomies were subtotal. Hysterectomy rates varied considerably across federal states: the rate for benign disease was lowest in Hamburg (213.8 per 100 000 women per year) and highest in Mecklenburg-West Pomerania (361.9 per 100 000 women per year). CONCLUSION: Hysterectomy rates vary markedly from one region to another. Moreover, even though recent studies have shown that bilateral ovariectomy is harmful to women under 50 who undergo hysterectomy for benign disease, it is still performed in 4% of all hysterectomies for benign indications in Germany.

First-trimester uterine scar assessment by transvaginal ultrasound.

OBJECTIVE: The objective of the study was to describe the assessment of lower segment uterine scar (LSCS) by transvaginal ultrasound (TVUS) during a first-trimester scan. STUDY DESIGN: Patients with a history of LSCS were prospectively enrolled over a 6 month period. Four groups were defined: type 1A, thin scar within cervicoisthmic canal (CIC); type 1B, thin above the internal os (IO); type 2A, dehiscent within the CIC; type 2B, dehiscent above the IO. Accuracy of first-trimester TVUS was investigated by blind testing a panel of 14 operators over a web-based dataset. RESULTS: The scar was visualized in 122 of 123 patients enrolled. Types 1A, 1B, 2A, and 2B occurred in 49.2%, 3.3%, 38.3%, and 9.2%, respectively. When blind tested, fetal medicine specialists achieved a median sensitivity of 82% and specificity of 100% for the detection of a scar. These were 83% and 87% for nonspecialists. CONCLUSION: First-trimester uterine scar assessment may become a valuable tool in early recognition of patients at risk of subsequent perinatal complications.

Patients' report on how endometriosis affects health, work, and daily life.

The objective of this study was to assess the burden of endometriosis by obtaining patient-reported outcome data describing the experience of living with this disease. Survey data from 107 women with self-reported, surgically diagnosed endometriosis showed that living with this disease may be characterized by physical limitations that disrupt health, work, and daily life.

Ultrasound assessment of the uterus and fallopian tube in infertile women.

In addition to the history and physical exam, the traditional evaluation of an infertile couple has included assessment of tubal patency, semen analysis, and assessment of ovulation. This article will assess the role of transvaginal ultrasound imaging of the uterus and fallopian tubes in infertile women either as an additional diagnostic test or as an aid to infertility treatment cycles. Transvaginal ultrasonography has become very sensitive, allowing for the detection of uterine lesions that otherwise might be missed. Understanding and interpreting the significance of the lesions is a major clinical challenge in the infertile patient.

[Diagnosis of uterine synechiae in patients with recurrent miscarriages: contribution of transvaginal hysterosonography]. / Diagnóstico de sinéquias uterinas por histerossonografia transvaginal.

BACKGROUND: The aim of this study was to determine the prevalence of uterine synechiae in patients with recurrent miscarriages and to evaluate the diagnostic accuracy of transvaginal ultrasound and of hysterosonography. METHODS: Sixty non-pregnant patients with a history of at least three previous consecutive miscarriages were evaluated by transvaginal ultrasound, hysterosonography and hysteroscopy to detect uterine synechiae. Hysteroscopy was considered the gold standard. Agreement of findings disclosed by transvaginal ultrasound and by the hysterosonography were evaluated according to the Kappa coefficient and their significance was tested. Significance was established at < 0. 05 (Alpha error = 5%). Sensitivity, specificity, positive and negative predictive values were determined for each method. RESULTS: Uterine synechiae were identified in 16 patients (26.7%). The accuracy of the transvaginal ultrasound and of the hysterosonography was 78.9% and 92.7%, respectively. When compared to the transvaginal ultrasound, hysterosonography had a much greater sensitivity (78. % vs. 20.0%) and a higher degree of agreement with hysteroscopy (Kappa = 80% vs. Kappa = 27%). CONCLUSION: For diagnosis of uterine synechiae, hysterosonography had a higher level of agreement with hysteroscopy than the transvaginal ultrasound. In patients with recurrent miscarriages transvaginal ultrasound is not recommended for the investigation of uterine synechiae because of its low sensitivity. Hysterosonography, on the other hand, seems to offer an important contribution especially because it is a simple, low-cost and accurate method for diagnosis of uterine synechiae.

Diagnóstico de sinéquias uterinas por histerossonografia transvaginal / Diagnosis of uterine synechiae in patients with recurrent miscarriages: contribution of transvaginal hysterosonography

OBJETIVO: Avaliar a prevalência de sinéquias uterinas em pacientes com aborto recorrente e a acurácia diagnóstica da ultra-sonografia transvaginal (US-TV) e da histerossonografia (HS). MÉTODOS: Sessenta pacientes não grávidas com passado de três ou mais abortos espontâneos consecutivos foram avaliadas por US-TV, HS e histeroscopia (HTC) para a pesquisa de sinéquias uterinas. A HTC foi considerada o padrão ouro do estudo. A concordância dos achados da US-TV e da HS foram avaliadas pelo coeficiente Kappa e sua significância foi testada. O nível de significância adotado foi de 0,05 (alfa = 5 por cento). Foram calculadas as medidas de sensibilidade, especificidade e valor preditivo positivo e negativo para cada um dos métodos. RESULTADOS: Observou-se a presença de sinéquias uterinas em 16 (26,7 por cento) pacientes. A acurácia da US-TV e da HS foram, respectivamente, de 78,9 por cento e 92,7 por cento. Comparativamente à US-TV, a HS foi muito superior quanto à sensibilidade (78,6 por cento versus 20 por cento) e concordância com a HTC (Kappa = 80 por cento versus Kappa = 27 por cento). CONCLUSÃO: Observou-se boa concordância da HS e concordância ruim da US-TV em relação à HTC para o diagnóstico de sinéquias uterinas. Devido à sua baixa sensibilidade, a US-TV não demonstrou ser um método aplicável à investigação de sinéquias uterinas em pacientes com aborto recorrente. A HS, por sua vez, parece oferecer importante contribuição nesta pesquisa, particularmente por sua simplicidade técnica, baixo custo e elevada acurácia diagnóstica.

Breed risk of pyometra in insured dogs in Sweden.

An animal insurance database containing data on over 200,000 dogs was used to study the occurrence of pyometra with respect to breed and age during 1995 and 1996 in Swedish bitches <10 years of age. A total of 1,803 females in 1995 and 1,754 females in 1996 had claims submitted because of pyometra. Thirty breeds with at least 800 bitches insured each year were studied using univariate and multivariate methods. The crude 12-month risk of pyometra for females <10 years of age was 2.0% (95% confidence interval = 1.9-2.1%) in 1995 and 1.9% (1.8-2.0%) in 1996. The occurrence of pyometra differed with age, breed, and geographic location. The risk of developing pyometra was increased (identified using multivariate models) in rough Collies, Rottweilers, Cavalier King Charles Spaniels, Golden Retrievers, Bernese Mountain Dogs, and English Cocker Spaniels compared with baseline (all other breeds, including mixed breed dogs). Breeds with a low risk of developing the disease were Drevers, German Shepherd Dogs, Miniature Dachshunds, Dachshunds (normal size), and Swedish Hounds. Survival rates indicate that on average 23-24% of the bitches in the databases will have experienced pyometra by 10 years of age. In the studied breeds, this proportion ranged between 10 and 54%. Pyometra is a clinically relevant problem in intact bitches, and differences related to breed and age should be taken into account in studies of this disease.

The cost of juvenile-onset recurrent respiratory papillomatosis.

OBJECTIVE: To assess the medical costs and the number of quality-adjusted life years lost owing to juvenile-onset recurrent respiratory papillomatosis (JORRP). DESIGN: We examined hospital and physician charges for JORRP surgical procedures in Maryland in 1994 adjusting for inflation and the cost-charge ratio. Centers for Disease Control and Prevention data on treatment intensity for JORRP were augmented with a review of treatment records for 18 patients with JORRP. Sensitivity analyses were performed. To illustrate the application of our cost estimates, we compare the costs of JORRP to the costs of the surgical procedures that would be necessary to prevent it. RESULTS: We find that the present value at birth of the cost of a single case of JORRP is $201,724 (range, $61,822-$474,334). The annual cost for a single case of JORRP is $57,996 (range, $32,407-$94,114). The annual cost of JORRP in the United States is between $40 million and $123 million depending on the prevalence. Cesarean section (CS) for women with condyloma has been suggested as a potential strategy to prevent JORRP, but its efficacy remains to be determined. Our results suggest that if only 1% of the CSs actually prevented JORRP, this strategy would be a cost-effective means to prevent JORRP. CONCLUSIONS: Studies to reduce the uncertainty surrounding the efficacy of CS and the effect of both CS and JORRP on families need to precede consideration of a policy of CS for women with clinically evident genital condyloma. Patients should be kept thoroughly informed about the role of CS for the prevention of JORRP and the nature of the remaining uncertainties.
