[Occupational blood exposure among Danish physicians--incidence and risk factors].

In a nation-wide questionnaire survey, the incidence and risk factors of percutaneous (PCE) and mucocutaneous (MCE) blood exposure among doctors in Denmark were studied. Of 9375 doctors, 6256 (67%) responded and 6005 were included for analysis. The highest incidence per person-risk-year (pry) was found in General Surgery, Neurosurgery, Obstetrics-Gynaecology and Orthopaedic Surgery (6.2-8.5 PCE/pry and 7.3-8.8 MCE/pry) followed by Anaesthesiology and Oto-rhinolaryngology (2.6-3.1 PCE/pry and 6.0-6.9 MCE/pry) and Pathology, Internal medicine, Radiology and Paediatrics (0.8-1.3 PCE/pry and 1.3-2.9 MCE/pry). Employment as senior as compared to junior doctor was associated with a higher risk of PCE and MCE among surgeons and a higher risk of PCE in anaesthetists, but a lower risk of PCE and MCE in Internal Medicine, Radiology and Paediatrics. Only 35% adhered to the basic principles of universal precautions and non-compliance was associated with a considerably increased risk of exposures, especially in non-surgical specialties. In conclusion, we found an unacceptably high incidence of occupational blood exposures among Danish doctors and preventive measures to reduce the incidence are strongly needed.

Jejuno-ileal bypass surgery in obesity. Gynecological and obstetrical aspects.

Changes in the quality of life were demonstrated in 38 young women who had undergone intestinal bypass surgery for obesity. After the operation about half the women complained of decreased libido or sexual activity, apparently due to psychological problems related to the development of asthenia secondary to metabolic disturbances. Bypass surgery resulted in a more regular pattern of menstruation but oral contraception was ineffective because of impaired intestinal absorption, perhaps due to a rapid transit time. No absolute contraindication to pregnancy was found but there are many risk-factors for both mother and fetus because of electrolyte disturbances, malnutrition and vitamin deficiency. Infants born to women after bypass surgery were found to have lower birth weights, were shorter, and the placental weight was low. It is necessary for these patients to have close medical supervision. The results of our study show that intestinal bypass surgery in young women has side effects which should not be ignored.

Tubal sterilization and risk of subsequent hospital admission for menstrual disorders.

OBJECTIVE: Our objective was to investigate tubal sterilization and subsequent hospitalization for menstrual disorders. STUDY DESIGN: Automated discharge data were used in a population-based cohort study of 7253 women aged 20 to 49 years with tubal sterilization (1968 through 1983) at Group Health Cooperative of Puget Sound. Comparisons were with an age-matched cohort of 25,448 nonsterilized women and a nonmatched cohort of 5283 spouses of men with vasectomies. RESULTS: In the sterilization cohort, 282 had hospitalization for menstrual disorders (curettage, n = 191; hysterectomy, n = 66; nonsurgical, n = 25). Risk of hospitalization for menstrual disorders was 2.4 times greater after tubal sterilization (95% confidence interval 2.0 to 2.9). This risk was 6.1 times greater for sterilized women aged 20 to 24 years (95% confidence interval 0.72 to 3.2). Compared with the risk for nonsterilized women whose spouses had a vasectomy, the risk was 1.6 times greater (95% confidence interval 1.3 to 2.1). Hospitalization for menstrual disorders was not more common after unipolar sterilization than after other methods, as might have been expected if the menstrual disorder was related to impaired uteroovarian circulation. CONCLUSIONS: Tubal sterilization is associated with a greater risk of hospitalization for menstrual disorders. A biologic association is not supported by these results.

The impact of an instant pregnancy test kit on the operations of a major hospital casualty department.

The records of all patients on whom a casualty department pregnancy test was performed during the first 4 months of 1986 were retrospectively examined and compared with the records of all patients who in the first 4 months of 1987 had had an instant pregnancy test performed in the same casualty department, to determine the impact of such a kit on diagnostic accuracy, operative procedures and related economic factors. It was demonstrated that instant pregnancy testing significantly improved the accuracy of provisional diagnoses and appeared to help in reducing the number of surgical procedures performed. Furthermore, it was shown that a combination of careful clinical assessment plus the appropriate application of an instant pregnancy test kit could result in a cost saving to the hospital of over $41,000 per annum.

Trends in evolution of specialty choice. Comparison of US medical school graduates in 1983 and 1987.

This study describes the evolution of specialty choices among US medical school seniors in 1983 and 1987. Its purposes were to determine the specialty interests of the 1987 cohort as these 11,264 students proceeded through medical school and to compare their evolving specialty plans with those of the 10,321 US medical school seniors in 1983. As the 1987 cohort advanced through medical school, they became increasingly interested in general and subspecialty internal medicine, psychiatry, obstetrics and gynecology, anesthesia, radiology and rehabilitation medicine and less interested in family practice, general surgery, pathology, and public health. Compared with the 1983 cohort, 1987 seniors were significantly less likely to choose general internal medicine and more likely to choose internal medicine and pediatric subspecialties. Similar proportions of each cohort of seniors chose family practice. Between 1983 and 1987, men's interest in pediatrics, general surgery, and obstetrics and gynecology declined, while their interest in the surgical subspecialties, anesthesia, and rehabilitation medicine increased.

Audit of emergency theatre utilisation.

This audit was undertaken to assess the utilisation of the emergency theatre in University College Hospital, Ibadan. It was also to find out if there was effective use of the emergency theatre space on a daily basis. Data was collected on all patients scheduled for emergency surgery excluding obstetric emergencies between May 1st and July 31st 1999. A total of 498 patients were booked for emergency surgery during the study duration and out of these, only 198 patients [38%] had their surgery performed. The number of patients booked per day ranged between 1 and 18 (Mean +/- S.D) [5.4 +/- 4.1], while the number operated ranged between zero and 9 (2.2 +/- 1.7). The General Surgery Unit had the highest number of cases booked (31.1%) and performed (38.9%). However, all the patients booked by the Gynaecological Unit (4.8% of total) were operated upon. Time interval between time of booking and the beginning of surgery ranged from 30 to 990 minutes (431 +/- 296.7), while duration of surgery ranged from 25 to 750 minutes [121 +/- 96.5]. Theatre utilisation during this study was between 5 to 50% (mean 26.9%) and the period of maximal utilisation was between 16.00 and 03.00 hours. Reasons why surgery was not performed on all (100%) booked patients included among others "Surgeons did not show up" (62%), "Surgery postponed by surgeons" (18%) and "Patient ill prepared for surgery" (10%). This study showed gross under-utilisation of emergency theatre space with contributing factors mainly human and preventable.

Changing indications for red cell transfusion from 2000 to 2004 in the North of England.

Falling donor numbers and the threat of transfusion-transmitted variant Creutzfeldt-Jakob disease may lead to shortages in the national blood supply. Knowledge of current patterns of transfusion and trends in usage will help predict future change in blood use. Our previous survey identified medical indications as the major reason for transfusion, but detailed information within this category was limited. We performed prospective surveys of indications for red cell transfusion for two 14-day periods in 2004 in the North of England, concentrating on medical reasons for transfusion. Data were obtained for transfusion indications of 9003 units, which accounted for over 99% of red cell issues from the regional blood centre during the study. In 2004, medical patients received 62% (5558 units) of all transfused units, surgical patients 33% (3001 units) and Obstetric & Gynaecology patients 5% (444 units). These figures compare with 52, 41 and 6% for Medicine, Surgery, and Obstetrics & Gynaecology in 1999/2000. The three largest uses of blood within the medical category were for patients with primary haematological disorders (18.2% of all transfused blood), for management of gastrointestinal haemorrhage (13.8%) and for patients with nonhaematological malignancies (8.8%). There has been a significant reduction in use of blood for surgical indications over the last 5 years, but an absolute increase in use of blood for medical indications. Lower transfusion triggers, education, use of cell salvage, the increasing price of a unit of red cells and changing population demographics may all have contributed to the reduction in surgical blood use. Promotion of good transfusion practice and alternatives to allogeneic transfusion should now focus on medical and surgical use of blood transfusion.

An analysis of the influences of maternal age, gestational age, contraceptive method, and the mode of primary treatment of patients with hydatidiform moles on the incidence of subsequent chemotherapy.

In relation to the total number of births in the United Kingdom there was an excess of hydatidiform moles arising in women over 34 years of age and possibly also under 15. The incidence of trophoblastic tumour requiring chemotherapy after hydatidiform mole was greatest in the 30 to 34 years age group and it was also high in the 20 to 24 years age group. This distribution appears to be influenced by the morphology of the moles, the mode of their removal and the use of oestrogens and progestogens in the post-evacuation period. The need for chemotherapy for trophoblastic tumour after evacuation of a hydatidiform mole was found to be two- to three-fold greater in patients who had undergone a medical induction, hysterectomy or hysterotomy compared with those whose hydatidiform moles had been evacuated by vacuum or surgical curettage, or who had aborted spontaneously. The increased risk of chemotherapy was most marked in the earlier weeks of gestation.

Obstetrician-gynecologist as primary care provider.

Obstetrics and gynecology is a unique field that combines preventive and primary care with female pelvic surgery and obstetrics. With the evolution of managed care, it has been a challenge to fit this field into the standard primary care paradigm. This article describes a 3-tiered, patient-oriented definition of primary care that encompasses the essential aspects of all primary care specialties, followed by a critical examination of how primary care specialties, including obstetrics and gynecology, fit into this definition. This approach suggests that to better meet the primary care needs of both patients and society, obstetrician-gynecologists must continue to improve their skills in preventive care, diagnosis and treatment of self-limited conditions, and diagnosis of serious nongynecologic conditions.
