Nationwide rates of conversion from laparoscopic or vaginal hysterectomy to open abdominal hysterectomy in Germany

The impact of obesity on vaginal hysterectomy and laparoscopically-assisted vaginal hysterectomy outcomes: A randomised control trial

OBJECTIVES

This prospective randomised control trial aimed to compare outcome measures of vaginal hysterectomy (VH) and laparoscopically-assisted vaginal hysterectomy (LAVH) in obese vs. non-obese women undergoing hysterectomy for benign uterine conditions with a non-prolapsed uterus. The primary objective of the study was to estimate operation time, uterine weight and blood loss amongst obese and non-obese patients undergoing VH and LAVH. The secondary objective was to determine any difference in hospital stay, the need for post-operative analgesia, intra- and immediate post-operative complications, and the rate of conversion to laparotomy for obese vs. non-obese patients undergoing VH and LAVH.

STUDY DESIGN

A prospective randomised control study was undertaken in the Department of Obstetrics and Gynaecology of the Charlotte Maxeke Johannesburg Academic Hospital (CMJAH). Women admitted between January 2017 and December 2019 for hysterectomy due to benign conditions, meeting the inclusion criteria set by the unit (vaginally accessible uterus, uterine size ≤ 12 weeks of gestation or ≤ 280gr on ultrasound examination, pathology confined to the uterus) were included in the study. The VH procedures were performed by the residents in training, under the supervision of specialists with large experience in vaginal surgery. All the LAVHs were performed by one surgeon (AC). In addition to the patient characteristics and surgical approach to hysterectomy, operative time, estimated blood loss, uterine weight, length of hospital stay, intra-operative and immediate post-operative complications were also recorded in obese and non-obese patient groups and comparatively analysed.

RESULTS

A total of 227 women were included in the study. 151 patients underwent VH and 76 LAVH, upon randomisation on a 2:1 basis, reflecting the habitual proportion of hysterectomy cases in the Urogynaecology and Endoscopy Unit at CMJAH. No significant differences were found in mean shift of pre-operative to post-operative serum haemoglobin, uterine weight, intra- and immediate post-operative complications, and convalescence period when comparing obese and non-obese patients in both the VH and LAVH groups. There was a statistically significant difference in operating time between the two procedures. The LAVHs took longer compared to the VHs to be performed (62.8 ± 9.3 vs. 29.9 ± 6.6 min in non-obese patients, and 62.7 ± 9.8 vs 30.0 ± 6,9 min for obese patients). All VHs and LAVHs were successfully accomplished without major complications.

CONCLUSION

VH and LAVH for the non-prolapsed uterus is a feasible and safe alternative for obese patients demonstrating similar perioperative outcome measures as non-obese women undergoing VH and LAVH. Where possible, VH should be preferred to LAVH as it is a safe route of hysterectomy, with operation time being significantly shorter.

Impact of oral anticoagulation on inhospital mortality of patients with hip fracture - Analysis of nationwide hospitalization data

OBJECTIVES

Oral anticoagulation (OAC) may have an impact on mortality in cases hospitalized for hip fracture (HF). We studied nationwide time trends of OAC prescriptions and compared time trends of inhospital mortality of HF cases with and without OAC in Germany DESIGN: Retrospective cohort study SETTING: Nationwide German hospitalization, Diagnosis-Related Groups Statistic PATIENTS/PARTICIPANTS: All hospital admissions for HF 60 years and older in the years 2006 through 2020.

INTERVENTION

Additional diagnosis with a personal history of long-term use of anticoagulants (ICD code Z92.1).

MAIN OUTCOME MEASUREMENTS

Inhospital mortality RESULTS: Cases hospitalized for HF 60 years and older increased by 29.5%. In 2006, 5.6% had a documented history of long-term use of OACs. This proportion rose to 20.1% in 2020. Age-standardized hospitalization mortality in HF cases without long-term use of OACs in males decreased steadily from 8.6% (95% confidence intervals 8.2 - 8.9) in 2006 to 6.6% (6.3 - 6.9) in 2020 and in females from 5.2% (5.0 - 5.3) to 3.9% (3.7 - 4.0). Mortality of HF cases with long-term use of OACs remained unchanged: males 7.0% (5.7 - 8.2) in 2006 and 7.3% (6.7 - 7.8) in 2020, females 4.8% (4.1 - 5.4) and 5.0% (4.7 - 5.3).

CONCLUSION

Inhospital mortality of HF cases with and without long-term OAC show different trends. In HF cases without OAC, mortality decreased from 2006 to 2020. In cases with OAC such a decrease could not be observed.

The hysterectomy: influence of the surgical method in benign disease on convalescence and quality of life

PURPOSE

The aim of this study was to evaluate the postoperative course after different methods of hysterectomy for benign diseases with special emphasis on time to recovery and patient-centred aspects such as postoperative quality of life and satisfaction.

METHODS

A collective of 242 women who had undergone vaginal hysterectomy (VH), laparoscopic supracervical hysterectomy (LASH) or total laparoscopic hysterectomy (TLH) for various benign conditions was studied in this retrospective investigation. Patients completed a standardised questionnaire addressing quality of life, recovery and sick leave as well as general questions on their postoperative course after hysterectomy.

RESULTS

A total of 242 cases were analysed (82 VH, 92 LASH and 68 TLH). The data demonstrate significant differences in regard to age between groups. The present study shows shorter hospitalisation with laparoscopy, with LASH patients returning to work at least one week earlier on average. There were no relevant differences in the overall postoperative course during the index hospital stay. In the long run, laparoscopic patients were not more satisfied with their choice than VH patients.

CONCLUSION

No significant long-term differences could be observed in terms of quality of life and overall postoperative satisfaction between VH and LH groups. In regard to socioeconomic aspects, laparoscopic approaches were associated with shorter hospitalisation and LASH patients returning to work at least one week earlier on average. Contrary to these data on objective recovery; however, a laparoscopic approach did not lead to patient-perceived, i.e. subjective improvement of time to full recovery.

Increased aortic repair in Germany correlates with reduction of death caused by aortic aneurysms but not aortic dissections

INTRODUCTION

We asked if there is a significant correlation between the increasing trend in aortic repair (AR) and decreasing aortic aneurysm (AA) and aortic dissection (AD) mortality? Therefore, we retrospectively analyzed all aortic repairs in patients with AA and AD and its correlation with disease-specific death rates and hospitalizations for ruptured AA and AD in Germany.

METHODS

We retrieved the number of cases hospitalized for AA and AD as well as the procedures in these cases from the Federal Bureau of Statistics (DRG statistics) and death rates from the national mortality statistic published by the Federal Statistical Office in Germany for the years 2006-2017.

RESULTS

From 2006 to 2017, the total number of hospitalized cases admitted with principal diagnosis of AA increased by 25.8% and that of AD by 56.7%. That of cases with the principal diagnosis of ruptured AA (rAA) remained unchanged (-2.5%) and that with rAD increased by 54.6%. The number of (open and endovascular) procedures in cases hospitalized for AA increased by 39.4% and for AD by 126.4%. The age-adjusted death rates in Germany for AA decreased from 4.0 to 2.9 per 100,000 inhabitants and that for AD increased from 1.0 to 1.4. The decrease in death attributed to AA cases can be described by linear regression as y = -0.0003*y + 6.7076 (p < 0.0001). Accepting this association between increased elective procedures and reduced AA mortality, each/all 1000 procedures save 0.3 lives per 100,000 inhabitants.

CONCLUSION

Despite increasing numbers of AR for AA and AD, only the mortality rate for all AAs decreased, while we did not observe a decrease in overall mortality of AD in Germany.

Incidence and determinants of hysterectomy among North Indian women: An 8-year follow-up study

Background

Despite indications of a rapid increase in the number of hysterectomies performed in India, very few studies have methodically investigated the rate and determinants of the incidence of hysterectomy. The present study aims to estimate the rate of incidence of hysterectomy and identify predictors/determinants of incident hysterectomy in a cohort of North Indian women.

Methods

In the present study, a cohort of 1,009 ever-married North Indian women (aged 30-75 years) was followed up after a median of 8.11 years. Those hysterectomized at the baseline (63) were excluded; and of the rest 946 participants, 702 (74.2%) could be successfully followed-up. During the baseline assessment, data about sociodemographic variables, reproductive history, menopausal status, physiological health, and selected blood biochemicals were collected. During the end-line assessment, data about sociodemographic variables, current menopausal status, and incident hysterectomy were recorded.

Results

The overall rate of incidence of hysterectomy was found to be 11.59 per 1,000 women-years, in the study population. Interestingly, the incidence rates were found to be similar among pre- and post-menopausal women. Further, while late age at menarche was found to be negatively associated with incident hysterectomy, folate repletion and high triglyceride (TG) at the baseline were found to be positively associated.

Conclusions

High rate of incident hysterectomy in the studied population points toward the huge burden of gynecological morbidity and the unavailability of non-invasive protocols. Such a situation warrants immediate policy intervention. Further, maintaining TG and folate within normal physiological ranges may be beneficial in gynecological ailments necessitating hysterectomy.

Administrative data in pediatric critical care research-Potential, challenges, and future directions

Heterogenous patient populations with small case numbers constitute a relevant barrier to research in pediatric critical care. Prospective studies bring along logistic barriers and-if interventional-ethical concerns. Therefore, retrospective observational investigations, mainly multicenter studies or analyses of registry data, prevail in the field of pediatric critical care research. Administrative health care data represent a possible alternative to overcome small case numbers and logistic barriers. However, their current use is limited by a lack of knowledge among clinicians about the availability and characteristics of these data sets, along with required expertise in the handling of large data sets. Specifically in the field of critical care research, difficulties to assess the severity of the acute disease and estimate organ dysfunction and outcomes pose additional challenges. In contrast, trauma research has shown that classification of injury severity from administrative data can be achieved and chronic disease scores have been developed for pediatric patients, nurturing confidence that the remaining obstacles can be overcome. Despite the undoubted challenges, interdisciplinary collaboration between clinicians and methodologic experts have resulted in impactful publications from across the world. Efforts to enable the estimation of organ dysfunction and measure outcomes after critical illness are the most urgent tasks to promote the use of administrative data in critical care. Clever analysis and linking of different administrative health care data sets carry the potential to advance observational research in pediatric critical care and ultimately improve clinical care for critically ill children.

Increasing Use of Anticoagulants in Germany and Its Impact on Hospitalization for Tooth Extraction

OBJECTIVES

 This article aimed to compare nationwide time trends of oral anticoagulant prescriptions with the time trend of hospitalization for tooth extraction (TE) in Germany from 2006 through 2017.

PATIENTS AND METHODS

 We derived the annual number of hospital admissions for TE from the Nationwide Hospital Referral File of the Federal Bureau of Statistics and defined daily doses (DDD) of prescribed anticoagulants in outpatients from reports of the drug information system of the statutory health insurance.

RESULTS

 From 2005 to 2017, annual oral anticoagulation (OAC) treatment rates increased by 143.7%. In 2017, direct oral anticoagulants (DOACs) represented 57.1% of all OAC treatments. The number of cases hospitalized for TE increased by 28.0 only. From all the cases hospitalized for TE in Germany in 2006, 14.2% had a documented history of long-term use of OACs. This proportion increased to 19.6% in 2017. Age-standardized hospitalization rates for all TE cases with long-term use of OACs increased from 6.6 in 2006 to 10.5 cases per 100,000 person-years in 2014 and remained almost unchanged thereafter.

CONCLUSION

 Our comparison showed that the large increase in OAC treatment rates in general from 2006 to 2017 had only a small impact on hospitalized TE cases with long-term use of OAC which flattens since 2014.

A randomized control trial comparing vaginal and laparoscopically-assisted vaginal hysterectomy in the absence of uterine prolapse in a South African tertiary institution

OBJECTIVES

The primary objectives of this study were to estimate blood loss, operation time and cost differences in patients undergoing vaginal hysterectomy (VH) versus laparoscopically-assisted vaginal hysterectomy (LAVH). The secondary objectives were to determine differences in hospital stay, need for postoperative analgesia, intra- and immediate post-operative complications, and the rate of conversion to laparotomy. VH was hypothesized to be the preferred route for hysterectomy for benign uterine conditions.

STUDY DESIGN

A randomized control study was undertaken at the Department of Obstetrics and Gynaecology of the Charlotte Maxeke Johannesburg Academic Hospital and included the women admitted between January 2017 and December 2019 for hysterectomy due to benign conditions, meeting the inclusion criteria (vaginally accessible uterus, estimated uterine size ≤ 12 weeks of gestation or ≤ 280 g on ultrasound examination and pathology confined to the uterus). Surgical procedures were performed by the residents in training under the supervision of specialists with large experience. The patient demographic characteristics, uterine weight, operative time, estimated blood loss(expressed as the difference between preoperative and postoperative day one serum haemoglobin),direct surgery-associated costs, intra- and immediate post-operative complications and the length of hospital stay were recorded and comparatively analysed among patients randomly placed in VH and LAVH group.

RESULTS

A total of 227 women were included (151 patients underwent VH and 76 LAVH, upon 2:1 randomization, performed on this way to reflect the previous pattern of operating of the unit). The patients were matched with respect to age, parity and body mass index. No significant differences between two groups were found in mean uterine weight and also in mean serum haemoglobin shift, intra- and immediate post-operative complications, and convalescence period duration. There were statistically significant differences in operating time and in cost between the two procedures. On average, LAVH took longer than VH to be performed (62.8 ± 9.3 vs 29.9 ± 6.6 min, p < 0.0001) and it was more costly, mainly due to the longer operating time and required disposables. An amount of 15698.20 South African Rand (ZAR) or 1145.85 United States Dollar (USD) more were needed to perform LAVH in comparison to VH. All VHs and LAVHs were successfully accomplished without major complications or conversation to laparotomy.

CONCLUSION

Our data indicate that VH is a feasible and safe alternative for a large group of women with benign pathology and non-prolapsed uteri, being a faster and less costly procedure than LAVH.

Formal institutional guidelines promotes the vaginal approach to hysterectomy in patients with benign disease and non-prolapsed uterus

OBJECTIVES

This study was undertaken at the Department of Obstetrics and Gynaecology of the Charlotte Maxeke Johannesburg Academic Hospital to determine if the use of formal guidelines and a standardised surgical technique would increase the rate of vaginal hysterectomy (VH) and result in an overall decline in open abdominal hysterectomy (AH).

STUDY DESIGN

All women admitted between July 2001 and December 2014 for hysterectomy due to benign conditions, meeting the guidelines criteria (vaginally accessible uterus, uterus ≤ 12 weeks size or ≤ 280 g on ultrasound examination and pathology confined to the uterus) were included. The surgical route was determined using the Unit surgical decision tree algorithm. In cases where the pathology was not confined to the uterus or success in VH was uncertain, laparoscopic assisted vaginal hysterectomy (LAVH) was performed. The VH procedures were performed by the residents in training, under the supervision of specialists with large experience in vaginal surgery. In addition to the patient characteristics and surgical approach to hysterectomy, length of hospital stay, intra-operative and immediate post-operative complications were also recorded and analysed.

RESULTS

A year before the initiation of the study, the percentage of all VHs undertaken in the Department was 9.8 % (mainly performed for utero-vaginal prolapse). During the study period, 1143 vaginal procedures (1017 VHs and 126 LAVHs) were performed. The most common indications were cervical dysplasia, uterine fibroids, dysmenorrhoea or abnormal uterine bleeding, adenomyosis, endometrial hyperplasia and chronic pelvic pain. Introducing a formal clinical decision tree algorithm and a standardised surgical technique resulted in an increase in the rate of VH to 48.4 % and overall decline in open AH from 91.2%-51.6%. Thus, the VH/AH ratio increased from 1/9 at the beginning of the study (July 2001) to 1/1 by its end (December 2014). In all cases, VH was performed without the need to convert the vaginal to the abdominal route.

CONCLUSION

The use of institutional guidelines for determining the hysterectomy route and a standardised VH technique resulted in an increased number of performed VHs. This provided an essential opportunity for residents to acquire, improve and maintain the skills required to safely perform VH.

The Fresh Frozen Cadaveric Study of Direct Pouch of Douglas Laparoscopic and Robotic Trocar Insertion for Vaginal Natural Orifice Transluminal Endoscopic Surgery

STUDY OBJECTIVE

To determine the distances and angles that assure a safe entry into the pouch of Douglas (POD) during blind laparoscopic and robotic trocar entry.

DESIGN

Trocars were inserted into the POD of 4 intact fresh frozen female pelves. Cadaveric dissection was performed, and the distance from the POD to the sacrum at rest and with maximal pressure to POD with the trocar was measured. In addition, the optimal angle for trocar insertion and entry was evaluated.

SETTING

Inova Advanced Simulation and Technology Evaluation Center.

PATIENTS

Fresh frozen cadavers with intact reproductive organs.

INTERVENTIONS

Vaginal POD trocar insertion.

MEASUREMENTS AND MAIN RESULTS

Measurements were recorded from the sacrum to the POD at rest and from the sacrum to the hymen with trocar pressure. The dissection demonstrated correct trocar placement in the POD of human cadaveric specimens. The mean distances from the sacrum to the hymen, the sacrum to the POD, and the sacrum to the POD with pressure were 18.75 cm, 9.75 cm, and 7.25 cm, respectively. After the deployment of the trocar, the tip was observed to be 2 cm below the cervix in the POD. The mean trocar angle to clear the sacral promontory and the neurovascular structures without injury to the uterus was 25° to 40° from the horizontal plane and 15° to 30° from the coronal plane.

CONCLUSION

A direct trocar entry into the POD has been found to be feasible in fresh frozen cadaveric specimens. This study provided valuable information for the angle of entry into the POD to facilitate vaginal and robotic trocar entry for minimally invasive gynecologic procedures.

Increasing use of anticoagulants in Germany and its impact on hospitalization rates for genitourinary bleeding

The aim of the study was to compare nationwide time trends of prescribed oral anticoagulants (OAC) with the time trend of genitourinary bleedings (GUB) in Germany from 2005 through 2016. The annual numbers of hospitalized patients with GUB coded as "hematuria", "excessive, frequent and irregular menstruation", "postmenopausal bleeding" or "abnormal uterine and vaginal bleeding" were extracted from the nationwide hospitalization file by the Federal Bureau of Statistics. Hospitalization rates were age-standardized using the German standard population 2011. Defined daily doses (DDD) of prescribed anticoagulants among outpatients for the same calendar period were extracted from reports of the statutory health insurance drug information system. Based on DDD, drug treatment rates per 100,000 person years (py) were calculated. From 2005 to 2016, annual OAC treatment rates per 100,000 py increased by 135.8% (from 901.4 to 2125.9). Until 2011 direct oral anticoagulants (DOAC) represented less than 0.1% of all OAC, but 49.9% in 2016. In the same period age-standardized rates of hospitalizations for hematuria increased continuously (annual change of 1.03 (95% CI 0.94-1.11) per 100,000 py), that of "postmenopausal" (- 1.93; 95% CI - 2.38 to - 1.49) or "excessive, frequent and irregular menstruation" decreased (- 1.25; 95% CI -1.62 to - 0.87) and that of "abnormal uterine and vaginal haemorrhage" remained almost unchanged. From all cases with hematuria 5.3% received at least 1 red blood cell concentrate (RBC) in 2005 and 8.2% in 2016 whereas all cases with the other three types of bleeding counted for 1.9% in 2005 and 3.8% in 2016. The time trends for GUB in all subgroups changed steadily and showed no effect of the disproportional increase of DAOCs until 2011. Our ecologic nationwide comparison of OAC treatment rates in outpatients and hospitalization rates for GUBs revealed that despite increasing OAC treatment rates from 2011 to 2016 the hospitalization rates for GUB showed steady annual changes unaffected by the increasing prescription rates of DOACs since 2011.

Correlation between obesity and manual lymphatic drainage in Germany - a retrospective analysis from 2008 to 2016

Backgrounds: Costs for manual lymphatic drainage (MLD) paid by the Statutory Health Insurances (SHI) have increased disproportionately in Germany in the last decade. There is no obvious reason that this increase is due to an increasing number of patients with lymph edema. We therefore assume that there are large numbers of patients with obesity and obesity-associated dependency syndrome who drive the cost of MLD and did a retrospective analysis of the correlation between hospitalization rates for lymph edema and obesity and MLD prescription rates in outpatients.

PATIENTS AND METHODS

Roughly 90 % of the German population is insured by the Statutory Health Insurance. From its reports we extracted data regarding costs and numbers of MLD session prescribed annually. Hospitalization rates for lymph edema (codes I89.*, I97.2 and Q82.0) and for obesity (ICD E66.*) were provided by the Federal Statistical Office after a specific remote analyses.

RESULTS

In the years 2008 to 2016, the MLD prescriptions in the individual federal states increased by + 43.5 % in Berlin to + 109.3 % in Mecklenburg-Western Pomerania. Number of hospitalizations with the principal diagnosis (condition, which caused the admission) hereditary and postmastectomy lymph edema are low and decreased in most federal states. Number of hospitalizations with the additional diagnosis (conditions that coexist at the time of admission or develop subsequently) obesity increased with a range from + 4.8 % in Baden-Württemberg to + 86.4 % in Mecklenburg-Western Pomerania. The correlation between the increase in prescribed MLD in the individual federal state and the increase in hospitalization rates per 1000 inhabitants of cases with obesity is greater (R² 0.4696) than with lymph edema (R² 0.0987).

CONCLUSIONS

Our analysis is in line with the hypothesis that there is a correlation between the increasing prescription rate of MLD and the increasing burden of obesity in Germany.

Trends in surgical treatment for breast cancer in Germany after the implementation of the mammography screening program

In Germany, the nationwide population-based mammography screening program (MSP) was introduced in 2005 and is full-running since 2010. By 2014, incidence rates for invasive breast cancer were very similar to those of the pre-screening era. Therefore, the ongoing effect of the MSP on breast cancer surgery rates can now be investigated. We analyzed population-based breast-conserving (BCS) and mastectomy (MET) surgery rates (per 100,000) among women aged < 50, 50-69 (eligible for the MSP), and 70+ years among women with in situ and invasive breast cancer during 2005-2015. For invasive breast cancer, both BCS and MET rates slightly increased in the age group < 50 years (38.3 in 2005 vs 42.5 in 2015 and 15.7 vs 18.2, respectively). In contrast, MET rates considerably decreased among women aged 50-69 and 70+ years (92 vs 65.4 and 155.4 vs 122.1, respectively), while BCS rates increased in both age groups (210.6 vs 254.4 and 147.2 vs 187, respectively). For in situ breast cancer, MET rates slightly increased in all age groups. BCS rates slightly increased in women aged < 50, but nearly doubled for women aged 50-69 (26.9 vs 49.1) and markedly increased in the 70+ age group (11.5 vs 16.1). During and after the implementation of MSP, there was a strong shift towards BCS within the screening-eligible age group and for women aged 70+ . Women with invasive breast cancer in these age groups may profit from screening with a decline of MET rates in favor of BCS rates at the expense of higher surgery rates for in situ breast cancer.

Increasing use of anticoagulants in Germany and its impact on hospitalization for gastrointestinal bleeding

OBJECTIVES

The aim of the study was to compare nationwide time trends of oral anticoagulant prescriptions with the time trend of gastrointestinal bleeding (GIB) in Germany from 2005 through 2016.

PATIENTS AND METHODS

The annual number of hospital admissions for GIB associated with gastric ulcers, duodenal ulcers, hematemesis, melena, hematochezia, and unspecified gastrointestinal bleeding (USGIH) was taken from the nationwide hospital referral file by the Federal Bureau of Statistics. The hospitalization rates were age-standardized using the German Standard Population 2011. The defined daily doses (DDD) of prescribed anticoagulants in outpatients for the same calendar period were taken from reports of the drug information system of the statutory health insurance. Based on DDD, drug treatment rates were calculated per 100,000 people.

RESULTS

From 2005 to 2016, the annual anticoagulant prescription rates per 100,000 persons increased by 135.8% (from 901.4 to 2125.9). By 2011, direct oral anticoagulants (DOAC) accounted for <0.1% of all anticoagulants, but 49.9% in 2016. Over the same period, age-standardized hospital admissions for GIBs per 100,000 person-years decreased by 14% (from 128.89 to 110.87). Hospitalization rates for gastric ulcer and duodenal ulcer decreased steadily, and those for hematoma, melena and hematochezia continued to increase. Only the USGIH decreased from 2005 to 2011 (annual change of -3.35 (95% CI -5.44; -1.25) per 100,000 person-years) and subsequently increased (0.61, 95% CI -0,42; 1.65). Of all GIB cases, 5.8% received at least 6 red blood cell concentrates in 2005 and 4.6% in 2016. The two-phase time trend for USGIH was no longer present in this subgroup.

CONCLUSION

Our nationwide comparison of outpatient OAC treatment rates and hospitalization rates for GIBs showed that GIB hospitalization rates declined despite increasing OAC treatment rates from 2005 to 2016. With increasing impact of DOACs after 2011, this decline was not affected.

Decentralized colorectal cancer care in Germany over the last decade is associated with high in-hospital morbidity and mortality

Purpose

Despite several national initiatives, centralization of cancer care in Germany remains insufficient for most malignancies. Currently, there is a plethora of centers, including 290 voluntary certified and audited colorectal cancer (CRC) centers by the end of 2017, in the nation with many patients still being treated outside of such centers. This study aimed to assess morbidity and mortality rates of surgical procedures for primary colorectal CRC in Germany over the last decade through a comprehensive unbiased analysis.

Patients and methods

We performed an analysis of the national diagnosis-related group inpatient statistics from 2005 to 2015 including all German hospitals. All patients who underwent surgeries for primary CRC during the study period were included.

Results

A total of 351,028 cases were analyzed (61.6% colonic and 38.4% rectal resections). The mortality rate of colonic resections remained high during the study period (4.9% in 2005 vs 4.5% in 2015; P=0.57). Reduced perioperative mortality after rectal surgery was observed only after 2012 compared to previous years (3.8% in 2005 vs 3.0% in 2015; P<0.001), with no further improvement. In-hospital morbidity such as anastomotic leak, wound infections, hemorrhage, pneumonia, deep vein thrombosis, and lung embolism did not improve for either rectal or for colonic surgery, but in contrast, most outcomes deteriorated over time.

Conclusion

The present study challenges the current national health policies aiming to improve outcomes of surgical patients. CRC care in Germany remains decentralized with high in-hospital morbidity and mortality rates. New national strategies focusing on the implementation of centralization and high-quality CRC care are urgently needed.

Laparoscopic hysterectomy for large uteri: Outcomes and techniques

Aim:

The aim of this study was to analyse our data of laparoscopic hysterectomy for large uteri (>16 weeks size) regarding their perioperative outcomes and possible factors for conversions to open surgery over 5 years. It also describes our techniques for the feasibility of performing such hysterectomies by the minimally invasive way.

Materials and Methods:

A five-year retrospective chart review was performed at the Minimal Access and Robotic Surgery Unit of the Department of Gynecology at Apollo Hospital, Hyderabad. Demographic and pre-operative and post-operative data were recorded. Clinical assessment including bimanual examination and surgery was made by a single senior surgeon. Intra-operative conversions, complications and post-operative complications were recorded.

Results:

A total of 128 women were included in this study, 5 patients underwent robotic-assisted hysterectomy. The average age was 44.4, body mass index - was 27.6 and size of the uterus was 17.5 weeks. The most common diagnosis was leiomyoma. The median Operating room (OR) time was 107 min. There was a need for myomectomy in 39.8%, extensive adhesiolysis in 33.6% and dense bladder adhesion in 26.6%. The average drop in haemoglobin was 1.72 g%, and hospital stay was 2 days. The specimen was removed by vaginal morcellation (2 cases via an umbilical port). Conversion to open surgery was required in 10.9% of cases. The conversion was significantly correlated with excessive haemorrhage and bladder injury but not with difficult hysterectomy, difficult bladder dissection or adhesions. There were 3 cases of bladder injury detected and managed intraoperatively.

Conclusion:

Laparoscopic hysterectomy is technically feasible and safe procedure for large uteri. The learning curve is about 50 cases and can be performed by experienced surgeons regardless of the size, number or location of the myomas without much morbidity.

Minimally invasive surgery for colorectal cancer remains underutilized in Germany despite its nationwide application over the last decade

Minimally invasive surgery (MIS) has superior short-term outcomes than open surgery (OS) for colorectal cancer (CRC). However, a nationwide dataset has not been analysed to confirm these findings. We evaluated the distribution and outcomes of MIS for CRC from 2005 to 2015; all in-patients with CRC surgery procedure codes were identified from hospital data, which are entered into the nationwide diagnosis-related group database and forwarded anonymised to the Federal Bureau of Statistics. We determined absolute MIS, morbidity, and mortality rates for specific sub-categories, including procedure type. We identified 345,913 in-patient files. The MIS rate increased from 6.4% (n = 2366; 2005) to 28.5% (n = 8363; 2015), with the highest rates for sigmoid colon (38%) and rectal (39%) resections. The overall conversion rate was 14.4%, without noticeable improvement over time. International Classification of Disease codes related to postoperative complications were documented more frequently after OS than after MIS. OS was associated with a higher mortality rate (4.7%) than MIS (1.8%) (P < 0.001), even after stratifying patients according to the resection site. Use of MIS remains low in Germany compared with that in other European countries. Underutilization of MIS has to be addressed in the future by promoting structured training programs and standardization of laparoscopic surgery.

Thromboembolic disease in females and males aged 10 to 39 years in Germany

BACKGROUND

We analysed differences in hospitalization rates for venous diseases such as pulmonary embolism (PE), deep vein thrombosis (DVT), sinus vein thrombosis (SVT), portal vein thrombosis (PVT), and Budd-Chiari syndrome (BCS) as well as for arterial diseases such as myocardial infarction (MI) and embolic stroke (ES) in females and males aged 10 to 39 years.

PATIENTS AND METHODS

Detailed lists of hospitalizations with the principal and additional diagnoses for PE (ICD-code I26.0 + I26.9), DVT (I80.0-I80.9), SVT (I67.6), PVT (I81), BCS (I82.0), MI (I21.0-I21.9), and ES (I63.1 + I63.4) in males and females aged 10 to 39 years in the years 2006 to 2015 were provided by the Federal Statistical Office in Germany.

RESULTS

Considering the 10-year period there were more female than male cases hospitalized with the principal diagnoses for PE, DVT, SVT, and BCS. Looking at the principal diagnosis of the year 2015, one can see a steep increase in numbers of hospitalization for PE, DVT, and SVT in females ranging from the ages 12 to 13 and 14 to 15 years compared to males. The curves of PE and DVT meet again in the age group between 32 and 33 years, but not for SVT. The greatest differences are seen at the end of the second and at the beginning of the third decade of life. In contrast, MI was more frequent in young males beginning at the age of 18 to 19 years. The number of female and male cases with ES and PVT were almost similar in the different age groups.

CONCLUSIONS

The presented data show higher hospitalization rates for females in the age group 10 to 39 years for different venous thrombosis but not for MI and ES.

Trends in Atrial Fibrillation and Prescription of Oral Anticoagulants and Embolic Strokes in Germany

BACKGROUND

The aim of the study was to compare trends in frequency of atrial fibrillation (AF) with the prescription rates of oral anticoagulants (OAC) and the incidence of embolic stroke (ES) from 2005 through 2014.

METHODS

Annual numbers of hospitalized patients with AF and ES were extracted from the Federal Bureau of Statistics. Defined daily doses (DDD) of prescribed OAC among outpatients were extracted from the insurance drug information system.

RESULTS

The number of cases hospitalized with the diagnosis AF increased continuously by 78.3% (1.25 Million in 2005 to 2.19 Million in 2014, p < 0.001), likewise frequency of ES increased by 89.0% (from 46,068 to 87,050, p < 0.001) and the number of prescribed DDD of OAC almost doubled by 105.4% (from 271,328 to 557,281, p < 0.001). There is an almost linear correlation between occurrence of AF and ES (R² = 0.9683). In contrast association between prescription rate of OAC and incidence of ES is not linear as there was a disproportional increase in OAC prescriptions beginning in the year 2010 that is not accompanied by a reduction of cases hospitalized with ES.

CONCLUSIONS

Our analysis of drug treatment rates for OAC in outpatients and hospitalization rates for ES revealed a disproportional increase in prescription of OAC beginning in the year 2010 that does not affect the number of cases hospitalized with ES.

Mortality in endovascular and open abdominal aneurysm repair – trends in Germany

Abstract. Background: We analysed trends in mortality of endovascular (EVAR) and open aortic repair (OAR) in patients hospitalized for abdominal aortic aneurysms (AAA) in Germany from 2005 to 2015. Patients and methods: We used national statistics published by the Federal Statistical Office in Germany to calculate mortality rate of patients hospitalized with ruptured (rAAA, n = 2,448 in 2005, n = 2,180 in 2015) and non-ruptured (iAAA, n = 11,626 in 2005, n = 14,205 in 2015) AAA. Results: Considering only those who were treated with EVAR or OAR, treatment rates of iAAA with EVAR increased to 78.2 % in males and 72.6 % in females in 2015 and treatment rates of rAAA to 36.9 % and 40.7 %, respectively. In cases with iAAA, death rates associated with EVAR decreased in males from 2.1 to 1.1 % (p = 0.0005) in the period from 2005 to 2015 but not in females (1.8 % in 2005 and 2.3 % in 2015, p = 0.8511). Similar trends are seen in cases with rAAA (males 30.1 % and 24 %, p = 0.1034, females 36.4 to 37.3 %, p = 0.8511). Death rates associated with OAR increased in males from 4.7 % in 2005 to 5.7 % in 2015 (p = 0.0103) and tended to increase in females from 6.8 to 8.2 % (p = 0.1476). In cases of rAAA, there were no changes. EVAR treatment rates increased in cases with iAAA in both genders with age, as well as in males with rAAA, but not in females. OAR associated death rates increased with age in rAAA (from around 30 % in the sixth/seventh decade of life to almost 80 % in cases with patients over the age of 90) and in iAAA (from 1.1 to 20 %). Conclusions: The general increase in EVAR procedures in males and females hospitalized for rAAA and iAAA went along with a decrease in in-hospital mortality in males treated with EVAR for iAAA only and an increasing mortality in males treated with OAR for iAAA.

In-hospital complications of vaginal versus laparoscopic-assisted benign hysterectomy among older women: a propensity score-matched cohort study

OBJECTIVE

This investigation compared the outcomes of vaginal and laparoscopic hysterectomies for nonprolapsed benign indications in older women.

METHODS

We conducted a population-based, retrospective propensity score-matched cohort study using data from the Taiwan's National Health Insurance program. Women who were aged 65 years or older with vaginal hysterectomy (n = 290) were compared with women who had laparoscopic hysterectomy for nonprolapsed benign indications (n = 290). Propensity score was calculated based on both patient- (age, socioeconomic status, residential urbanicity, comorbidity, status of any prior catastrophic illness, surgical diagnosis, and year of hysterectomy) and provider-related characteristics (physician's age and sex, hospital accreditation level, and ownership type).

RESULTS

Women undergoing laparoscopic hysterectomy were not associated with increased risk of inpatient readmission within 30 days, in-hospital mortality, and in-hospital (including intraoperative) complications when compared with those who had vaginal hysterectomy. Women in the laparoscopic group had significantly shorter hospital stays than those in the vaginal group. The bleeding complications were mostly due to blood transfusion (2.1% in vaginal and 0.7% in laparoscopic hysterectomy groups) and urinary tract infection (1.0% in vaginal and 1.7% in laparoscopic hysterectomy groups). The surgical injury (intraoperative) complications included mostly surgical laceration of the urinary tract (0.7% in vaginal and 0.3% in laparoscopic hysterectomy groups).

CONCLUSIONS

Advanced age alone should not be the limiting factor for surgical referral of laparoscopic hysterectomy. The shorter hospital stay and low in-hospital complications associated with laparoscopic, as opposed to vaginal hysterectomies, are important attributes of a surgical procedure essential to the postoperative care in older women aged 65 years or more.

Using international data to set benchmarks for morbidity outcomes after hysterectomy

OBJECTIVE

To set an international benchmark for monitoring morbidity after hysterectomy.

METHODS

In a retrospective, observational study, data were assessed from women who underwent abdominal, vaginal, or laparoscopic hysterectomy in three countries (Australia, England, and the USA) between 2008 and 2012. The main outcome measures were length of stay (LOS), readmission, hemorrhage, and intraoperative conversion.

RESULTS

Overall, 32 181 procedures were included. The intraoperative conversion rate from vaginal and laparoscopic to abdominal hysterectomy was 1.5%. The LOS was significantly higher after abdominal surgery (3 days) than after vaginal (2 days; P<0.001) or laparoscopic (1 day; P<0.001) surgery. LOS was also higher after conversion (3 days) than after vaginal and laparoscopic hysterectomy (P<0.001 for both). Conversion cases had the highest rate of hemorrhage (7.5% vs 2.4% for abdominal, 1.8% vaginal, and 1.2% laparoscopic) and readmission (5.0% vs 4.2% for abdominal, 3.1% vaginal, and 2.8% laparoscopic). The odds of readmission were higher after abdominal than after laparoscopic hysterectomy (odds ratio 1.41, 95% confidence interval 1.19-1.67; P<0.001).

CONCLUSION

The morbidity associated with different surgical approaches to hysterectomy, including after intraoperative conversion, should be used as a benchmark. There is a need to measure and publish morbidity data after hysterectomy.

Nationwide shoulder arthroplasty rates and revision burden in Germany: analysis of the national hospitalization data 2005 to 2006

BACKGROUND

The aim of this study was to provide nationwide shoulder arthroplasty rates in Germany based on the national hospitalization file and to estimate the revision burden for shoulder arthroplasty and its determinants.

METHODS

We analyzed the nationwide, population-based, German diagnosis-related groups data from the years 2005 and 2006. Procedure codes and diagnosis were analyzed for each hospitalization. Overall, 16,488 primary shoulder arthroplasties and 1302 revisions were performed during the study period. Age-standardized rates, age-specific rates, rates by indication, and revision burden were calculated.

RESULTS

The age-standardized hemiarthroplasty (HA) rates were 3.6 per 100,000 person-years (standard error [SE], 0.1) for men and 9.3 per 100,000 person-years (SE, 0.1) for women and clearly exceeded the age-standardized total shoulder arthroplasty (TSA) rates of 1.7 per 100,000 person years (SE, 0.1) for men and 3.7 per 100,000 person-years (SE, 0.1) for women. The revision burden was 4.7% for HA and 15.0% for TSA. Multivariable-adjusted analysis showed increasing age was associated with a lower relative burden of revision, and an increased Charlson comorbidity index and male gender were associated with a higher relative burden of revision. The adjusted relative burden of revision was considerably higher for TSA than for HA (adjusted relative burden of revision, 2.89; 95% confidence interval, 2.60-3.22).

CONCLUSION

We found more than 2-fold higher primary rates for HA than for TSA and up to 3-fold higher shoulder arthroplasty rates for women than for men. TSA had a 3-fold higher relative burden of revision than HA.

Educational level, prevalence of hysterectomy, and age at amenorrhoea: a cross-sectional analysis of 9536 women from six population-based cohort studies in Germany

Background

Hysterectomy prevalence has been shown to vary by education level. Hysterectomy influences age at amenorrhoea. The aim of this study was to examine these associations in Germany within population-based data sets.

Methods

Baseline assessments in six population-based cohorts took place from 1997 through 2006 and included 9,548 women aged 20–84 years. All studies assessed hysterectomy history, school and professional degrees. Degrees were categorized into three levels each. Adjusted prevalence ratios and 95% confidence intervals (95% CI) were estimated.

Results

Prevalences were higher in West Germany than East Germany, increased by age, and leveled off starting at 55–64 years. The age- and study-adjusted prevalence ratio (lowest versus highest school level) was 2.61 (95% CI: 1.28-5.30), 1.48 (95% CI: 1.21-1.81), and 1.01 (95% CI: 0.80-1.28) for women aged 20–45, 45–64, and 65 and more years respectively. The estimated adjusted prevalence ratios per one unit decrement of the educational qualification score (range 1 = lowest, 8 = highest) were 1.29 (95% CI: 1.02-1.64), 1.08 (95% CI: 1.04-1.12), and 0.98 (95% CI: 0.93-1.03) for women aged 20–44, 45–64, and 65–84 years respectively. Age at amenorrhoea was on average 6.2 years lower (43.5 years versus 49.7 years) among women with a history of hysterectomy than those without.

Conclusions

Lower educational level was associated with a higher hysterectomy prevalence among women aged 20–64 years. Several mediators associated with educational level and hysterectomy including women’s disease risk, women’s treatment preference, and women’s access to uterus-preserving treatment may explain this association. At population level, hysterectomy decreases the age of amenorrhoea on average by 6.2 years.

Ten years of progress--improved hysterectomy outcomes in Finland 1996-2006: a longitudinal observation study

OBJECTIVES

To study the outcome of various hysterectomies in 2 years 1996 (N =10110) and 2006 (N=5279). The hypothesis was that the change in operative practices in 10 years has resulted in improvements.

DESIGN

2 prospective nationwide cohort evaluations with the same questionnaire.

SETTING

All national operative hospitals in Finland.

PARTICIPANTS

Patients scheduled to either abdominal hysterectomy (AH), vaginal hysterectomy (VH) or laparoscopic hysterectomy (LH) for benign disease.

OUTCOME MEASURES

Patients' characteristics, surgery-related details and complications (organ injury, infection, venous thromboembolism and haemorrhage).

RESULTS

The overall complication rates fell in LH and markedly in VH (from 22.2% to 11.7%, p<0.001). The overall surgery-related infectious morbidity decreased in all groups and significantly in VH (from 12.3% to 5.2%, p<0.001) and AH (from 9.9% to 7.7%, p<0.05). The incidence of bowel lesions in VH sank from 0.5% to 0.1% and of ureter lesions in LH from 1.1% to 0.3%. In 2006 there were no deaths compared with three in 1996.

CONCLUSIONS

The rate of postoperative complications fell markedly in the decade from 1996 to 2006. This parallels with the recommendation of the recent meta-analyses by Cochrane collaboration; the order of preference of hysterectomies was for the first time precisely followed in this nationwide study.

TRIAL REGISTRATION

The 2006 study was registered in the Clinical Trials of Protocol Registration System Data (NCT00744172).

Clinical relevance of conversion rate and its evaluation in laparoscopic hysterectomy

STUDY OBJECTIVES

To estimate the current conversion rate in laparoscopic hysterectomy (LH); to estimate the influence of patient, procedure, and performer characteristics on conversion; and to hypothesize the extent to which conversion rate can act as a means of evaluation in LH.

DESIGN

Prospective cohort study (Canadian Task Force classification II-2).

SETTING

The study included 79 gynecologists representing 42 hospitals throughout the Netherlands. This reflects 75% of all gynecologists performing LH in the Netherlands, and 68% of all hospitals.

PATIENTS

Data from 1534 LH procedures were collected between 2008 and 2010.

INTERVENTION

All participants in the nationwide LapTop registration study recorded each consecutive LH they performed during 1 year.

MEASUREMENTS AND MAIN RESULTS

Conversion rate and odds ratios (OR) of risk factors for conversion were calculated. Conversions were described as reactive or strategic. The literature reported a conversion rate for LH of 0% to 19% (mean, 3.5%). In our cohort, 70 LH procedures (4.6%) were converted. Using a mixed-effects logistic regression model, we estimated independent risk factors for conversion. Body mass index (BMI) (p = .002), uterus weight (p < .001), type of LH (p = .004), and age (p = .02) had a significant influence on conversion. The risk of conversion was increased at BMI >35 (OR, 6.53; p < .001), age >65 years (OR, 6.97; p = .007), and uterus weight 200 to 500 g (OR, 4.05; p < .001) and especially >500 g (OR, 30.90; p < .001). A variation that was not explained by the covariates included in our model was identified and referred to as the "surgical skills factor" (average OR, 2.79; p = .001).

CONCLUSION

Use of estimated risk factors (BMI, age, uterus weight, and surgical skills) provides better insight into the risk of conversion. Conversion rate can be used as a means of evaluation to ensure better outcomes of LH in future patients.

Regional and temporal variation in hysterectomy rates and surgical routes for benign diseases in the Netherlands

OBJECTIVE

To provide descriptive statistics on hysterectomy for benign gynecological conditions in the Netherlands and to analyze regional and temporal variations in hysterectomy rates and surgical routes.

DESIGN

Retrospective cohort study.

SETTING

Dutch hospitals.

POPULATION

All women with a hysterectomy for benign gynecological conditions in the Netherlands in 1995-2005.

METHODS

This study is based on an analysis of the Dutch registry of hospital admissions for 1995-2005.

MAIN OUTCOME MEASURES

The age-adjusted hysterectomy rate and age- and diagnosis-adjusted proportion of vaginal hysterectomies for each Dutch healthcare region and time period.

RESULTS

The average annual crude hysterectomy rate for benign disease only, was 17.2 per 10,000 women of all ages. The vaginal route was chosen for 50.8% of the patients. During the study period, the number of hysterectomies for bleeding disorders declined almost 25%. Among 27 Dutch healthcare regions, the age-adjusted hysterectomy rates for bleeding disorders and pelvic organ prolapse varied 2.2- and 2.3-fold, respectively. The average annual age- and diagnosis-adjusted proportion of vaginal hysterectomies varied from 43.4 to 63.8%. The regional differences with regard to rate and proportion declined slightly over time.

CONCLUSIONS

The Netherlands is among the countries with the lowest hysterectomy rates and the highest proportion of vaginal hysterectomies. The regional differences indicate that a further decrease in the hysterectomy rates and an increase in the proportion of vaginal hysterectomies are possible.

Gynecologists' characteristics associated with the likelihood of performing laparoscopic-assisted hysterectomy: a nationwide population-based study

OBJECTIVE

With continuing development of minimally invasive techniques in gynecology, hysterectomy with laparoscopic assistance is increasingly performed. This study aimed to examine the relationship between the characteristics of gynecologists and the likelihood of performing laparoscopic-assisted hysterectomy (LH) under the case payment system of Taiwan's National Health Insurance.

STUDY DESIGN

A retrospective population-based study was conducted based on the data from Taiwan's National Health Insurance Research Database. A total of 56,532 female residents aged 20 years and older who underwent total hysterectomy with or without laparoscopic assistance between 2004 and 2006 were included in the study. The gender, age and practice volume of their gynecologists were noted. Odds ratios (ORs) and 95% confidence intervals (CIs) were estimated by univariate and multivariate logistic regression analyses.

RESULTS

Of the women selected, 30,478 underwent traditional total hysterectomy (TH) and 26,054 underwent LH. After controlling for clinical and nonclinical factors, male gynecologists (OR 1.65, 95% CI 1.55-1.76) were more likely to perform LH than their female colleagues. Gynecologists aged 60 years and older (OR 0.31, 95% CI 0.29-0.39) had the lowest likelihood of performing LH compared with their counterparts. In addition, surgeons with low-volume practice (OR 0.31, 95% CI 0.29-0.33) also had a significantly lower probability of performing LH compared with other surgeons.

CONCLUSION

A higher likelihood of performing LH was observed among male and younger gynecologists with high-volume practice in Taiwan. This finding suggests that differences in practice patterns and surgical treatment decision may explain the variation in the approaches to laparoscopy-assisted hysterectomies.

CONDENSATION

Differences in practice patterns and surgical treatment decisions may explain the variation in the approaches to laparoscopic-assisted hysterectomies.

Thyroid cancer surgery in Germany: an analysis of the nationwide DRG statistics 2005-2006

PURPOSE

In 2004, a Diagnosis Related Groups (DRG)-based hospital reimbursement system became mandatory in Germany. The aim of this study was to provide nationwide data on the surgery of thyroid cancer by analyzing DRG statistics of the years 2005 and 2006.

METHODS

The unit of analysis was hospital admission with a diagnosis of thyroid cancer. We assessed the influence of age, sex and region on the relative frequency of thyroid cancer-related hospitalisations with surgery of the thyroid and we measured the association between hospitalisation rates and incidence rates of thyroid cancer among the Federal States of Germany.

RESULTS

Over the period 2005 to 2006, 11,107 thyroid cancer-associated hospitalisations included surgical treatment of the thyroid. The age-standardised DRG-based hospitalisation rates and the corresponding cancer registry-based incidences of thyroid cancer were positively associated. Overall, 68% of the hospitalisations with thyroid surgery included a total thyroidectomy. The percentage of surgery of the thyroid with a total thyroidectomy was nearly identical among men and women, decreased among men aged over 60 and varied considerably by region (minimum, 48% in Saarland; maximum, 78% in Saxony-Anhalt).

CONCLUSIONS

Our analyses of DRG statistics provide for the first time representative population-based data of the surgical management of thyroid cancer patients in Germany. Despite an identical health care system all over Germany and existing guidelines for surgical treatment of thyroid cancer, we observed a considerable regional variation in the proportion of total thyroidectomies performed in Germany.

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.
