An evaluation of educational outreach to general practitioners as part of a statewide cervical screening program

OBJECTIVES: The purpose of this study was to determine the acceptability, effectiveness, and cost of a face-to-face educational outreach intervention in the context of a program aimed at increasing cervical screening in Victoria, Australia. METHODS: All identified general practitioners in a specified intervention area were offered a visit by a general practitioner educator. Practitioners completed a questionnaire evaluating the acceptability of the visit. Odds ratios for a woman being screened in the 3 months following the visits were determined. RESULTS: Fifty-nine general practitioners (69.4%) accepted the offer of a visit. Most found both the process and the content of the intervention to be acceptable. The intervention and nonintervention regions did not differ either before or after the intervention. In both regions, there was a statistically significant increase in number of Pap tests performed. There was no difference in the change in screening between the two regions. Costs were estimated at Au$34 per general practitioner visited. CONCLUSIONS: This strategy cannot be recommended for widespread use in a cervical screening program.     

Ambulatory health care visits by children: principal diagnosis and place of visit

OBJECTIVES: This report presents national estimates of ambulatory health care use by children under 15 years of age according to principal diagnosis, place of visit (physician office, hospital outpatient department, and hospital emergency department), and patient characteristics (age, sex, and race). METHODS: Data were from the National Ambulatory Medical Care Survey and the National Hospital Ambulatory Medical Care Survey. Data were from 1993-95. RESULTS: In 1993-95 children under 15 years of age made 165.3 million visits per year (289 visits per 100 children). Visit rates were highest among infants and varied inversely with age. Visit rates were 43 percent higher among white children than black children. Three-quarters of ambulatory visits occurred in physician offices, 8 percent in hospital outpatient departments, and 14 percent in hospital emergency departments. Visits by white children were more likely to occur in physician offices than visits by black children (81 percent and 54 percent). Conversely, visits by black children were more likely to occur in hospital outpatient departments (19 percent and 7 percent) and hospital emergency departments (28 percent and 12 percent) than visits by white children. The following principal diagnoses accounted for almost 40 percent of visits: well-child visit, 15 percent; middle ear infection, 12 percent; and injury, 10 percent. Rates for well-child visits were almost 80 percent higher among white infants than black infants. Continued monitoring of these differences in use of ambulatory care among children are needed, particularly in view of the possible impact of changes in the health care system on these differences.     

Patterns of various modes of delivery in relation to presence of different risk factors in term pregnant mothers--a case-control study

A case-control study, was carried out, which aimed to determine whether a relation exists between risk factors present in mother and the mode of delivery i.e., outcome. Cases were those mothers who had one or more risk factors present during pregnancy (namely, short stature, malpresentation, antepartum haemorrhage, pre-eclamptic toxaemia/eclampsia, anaemia-haemoglobin less than 10 g/dl, twins, bad obstetric history, prolonged pregnancy, history of previous caesarean section and instrumental delivery, pregnancy associated with general diseases, prolonged difficult labour and RH-iso-immunisation). Controls were those mothers who did not have any of the above mentioned risk factors. Total of 250 cases and 250 controls were taken. Results showed that surgical and instrumental deliveries were strongly associated with presence of risk factors (odd's ratio: 5.94; attributable risks: 72%). Out of risk factors among cases, most common indication of caesarean section, was previous caesarean section followed by malpresentation, prolonged difficult labour and short statured mothers in descending order.     

Elective cesarean section is preferred after the completion of a minimum of 38 weeks of pregnancy

OBJECTIVE: To determine the frequency of neonatal respiratory morbidity following elective caesarean delivery at term and to identify prognostic factors for this morbidity. DESIGN: Retrospective. SETTING: Academic Hospital Utrecht/Wilhelmina Children's Hospital Neonatal Intensive Care Unit, Utrecht, the Netherlands. METHOD: All elective caesarean deliveries in the Academic Hospital Utrecht from the period 1990-1995 were studied. Also, neonates were included who were admitted for intensive neonatal care because of respiratory insufficiency following elective caesarean delivery in the region surrounding Utrecht. An elective caesarean delivery was defined as a delivery performed after 37 weeks of gestation without any complicating factor that might influence the timing of delivery. Prognostic factors for neonatal morbidity after caesarean delivery were identified by multivariate logistic regression analysis. RESULTS: During 1990-1995, 272 elective caesarean deliveries after 37 weeks of gestation were performed that fulfilled the inclusion criteria; 5.1% of the neonates were admitted to the medium care unit because of respiratory problems. The relative risk of respiratory morbidity after delivery by caesarean section with a gestational age of 39-42 weeks compared with a gestational age of 37-38 weeks, was 0.14 (95% confidence interval: 0.03-0.64; p < 0.001). Male sex was a cofactor. Nine neonates of whom 8 (90%) had a gestational age of less than 39 weeks were admitted to the intensive care unit. CONCLUSION: Most of neonatal respiratory morbidity could have been avoided by postponement of the at-term elective caesarean section until a certain gestational age of at least 38 complete weeks. An elective caesarean section should not be performed before that period.     

Effects of 60 Hz electromagnetic fields on early growth in three plant species and a replication of previous results

OBJECTIVE: To examine the relation between obstetric factors and the prevalence of urinary incontinence three months after delivery. DESIGN: 2134 postal questionnaires sent between August 1989 and June 1991. SETTING: Teaching hospital in Dunedin, New Zealand. SUBJECTS: All women three months postpartum who were resident in the Dunedin area. MAIN OUTCOME MEASURE: Prevalence of urinary incontinence. RESULTS: 1505 questionnaires were returned (70.5% response rate). At three months postpartum 34.3% of women admitted to some degree of urinary incontinence with 3.3% having daily or more frequent leakage. There was a significant reduction in the prevalence of incontinence for women having a caesarean section, in particular in primiparous women with a history of no previous incontinence (prevalence of incontinence following a vaginal delivery 24.5%, following a caesarean section 5.2% P = 0.002). There was little difference between elective caesarean sections and those carried out in the first and second stages of labour. The odds ratios for women having a caesarean section were 0.4 (95% confidence interval (CI) 0.2.-0.7) (all women and all primiparae) and 0.2 (95% CI 0.0-0.6) (primipara with no previous incontinence) in comparison with those having a normal vaginal delivery. The prevalence of incontinence was also significantly lower in women having had two caesarean sections (23.3%; P = 0.05) but similar in those women having three or more caesarean sections (38.9%) in comparison with those women who delivered vaginally (37.7%). Other significant independent odds rations were found for daily antenatal pelvic floor exercises (PFE) (0.6, 95% CI 0.4-0.9), parity > or = 5 (2.2, 95% CI 1.0-4.9) and pre-pregnancy body mass index (1.07, 95% CI 1.04-1.10). CONCLUSIONS: Adverse risk factors for urinary incontinence at three months postpartum are vaginal delivery, obesity and multiparity (> or = 5). Caesarean section and daily antenatal PFE appear to be protective, although not completely so.     

Rural obstetrics in NSW

Rural general practitioners are responsible for providing obstetric services to the majority of women living in rural communities. This paper reports a comparison of 5,950 deliveries conducted by rural GPs in NSW during 1990-1991 with all 88,275 deliveries during the same period in NSW. No evidence that obstetric care in accredited rural GP obstetric units is of less than acceptable standards could be found. There is scope to increase the use of rural obstetric units for the training of future rural GP obstetricians.     

Delivery of extremely large infants

The purpose of this retrospective study was to find out if more effort should be applied to the diagnosis of extremely large infants, with a birth weight of 5,000 grams or more, and if elective caesarean section can be recommended. In the Department of Obstetrics, Herning Central Hospital, Denmark, 67 mothers delivered an infant with a birth weight of 5000 g or more over a ten year period. This index group was compared with a matched group with infants of normal weight. The result showed significantly more caesarean sections in the index group (24% versus 5%, p = 0.002). Shoulder dystocia and Duchenne-Erb's palsy were more frequent as well. Sixteen percent in the index group were admitted to the paediatric department, but the Apgar scores were not significantly lower. Except for one, all the infants showed complete recovery. In conclusion, elective caesarean section can not be generally recommended for an estimated birthweight exceeding 5,000 g, if a trained obstetrician is present at delivery.     

Urinary tract injuries during obstetric intervention

A retrospective case record review of obstetric urinary tract injury in the Grampian region from 1976 to 1993 identified 16 cases of bladder injury (0.1 per 1000 deliveries, 1.4 per 1000 caesarean sections and four cases of ureteric injury (0.03 per 1000 deliveries, 0.27 per 1000 caesarean sections). Diagnosis of bladder injury was immediate, but of ureteric injury often delayed. Although the injury rates are lower than previously reported and previously reported risk factors not confirmed, this audit has resulted in guidelines for junior staff, compliance with which will be monitored, and every case of urinary tract injury will be reviewed.     

Breech delivery. Selection by X-ray pelvimetry

An attempt was made to evaluate the possible benefit of selecting women for vaginal breech delivery at term by radiological pelvimetry. Information from medical records on 276 singleton breech deliveries were analysed. A total of 188 breech presentations were diagnosed before the onset of labour, pelvimetry was performed in 74 women, where pelvic dimensions too small for recommendation of vaginal breech delivery were found in 30 cases. The overall rate of caesarean section was 78%, among diagnosed patients it was 84% and 64% among undiagnosed breech presentations. Rates of morbidity (low Apgar score and admission to the neonatal care unit) did not differ significantly between infants delivered vaginally or by elective caesarean section. The material, however, is too small for valid conclusions regarding safety of vaginal delivery of term breech in women selected by criteria including estimate of pelvic size.     

Cloning and characterization of plastid ribosomal protein S16 gene from potato (Solanum tuberosum L. cv Désirée)

STUDY OBJECTIVE: To determine whether an intensive educational campaign of emergency department personnel on the organ donor and procurement process would result in both increased organ donor referrals and organs procured. METHODS: A retrospective review of the performance of an urban teaching ED in identifying and referring potential organ donor candidates was performed. Subsequently an intensive educational campaign of all ED staff, in conjunction with the Regional Organ Procurement Agency of Southern California (ROPA), was initiated. Physicians and nurses were educated about the procurement process, and a ROPA representative was on call 24 hours a day to assist in this process. The need for aggressive resuscitation and vital sign maintenance in potential donors as a strategy to promote organ recovery was emphasized. Reeducation by ROPA occurred every 2 to 3 months. The identification and referral rates were then retrospectively reviewed to evaluate any improvement. RESULTS: In 1994 the initial referral rate of potential organ donors from the ED was 30% (3 of 10) resulting in no organs procured. After the intervention the referral rate increased to 100% (25 of 25) in 1995 (P < .0001). The number of actual donors procured was 0 in 1994, 5 in 1995, and 9 in 1996. The increased ED referrals resulted in 14 and 32 organs procured in 1995 and 1996, respectively. CONCLUSION: Emergency physicians are in a unique position as first caregivers to interact with both potential donors and their families. With intensive education of ED staff, proper identification and referral, as well as timely intervention by organ procurement representatives, the consent and donation rate of organs for transplantation can be increased and maintained.     

Cost-effectiveness of the arthritis self-help course

OBJECTIVE: To evaluate the cost-effectiveness of the Arthritis Self-Help Course in reducing the pain of arthritis, the leading cause of disability in the United States and a common problem among older adults. METHODS: A decision model was used to examine the cost-effectiveness of the Arthritis Self-Help Course among individuals with arthritis over a 4-year analytic horizon from 2 perspectives, namely, society and the health care system. The Arthritis Self-Help Course was assumed to reduce pain by 20% and physician visits for arthritis by 40% among individuals receiving conventional medical therapy. Estimates for program costs, costs for physician visits, and time and transportation costs were derived from the published literature and expert opinion. Sensitivity analyses were conducted on all relevant parameters. Arthritis pain and costs (program, physician visit plus/minus time and transportation) were expressed as cost per person per unit reduction in pain. Because nearly all analyses showed the program to be cost saving, we simply report the reduction in joint pain and the cost savings, because standardizing cost savings is not a useful concept. RESULTS: From both the societal and health care system perspectives, the Arthritis Self-Help Course was cost saving in base-case analyses (reducing pain by 0.9 units while saving $320 and $267, respectively) and throughout the range of reasonable values used in univariate sensitivity analyses. Cost savings were due primarily to reduced physician visits. CONCLUSIONS: The Arthritis Self-Help Course is a cost-saving intervention that further reduces arthritis pain among individuals receiving conventional medical therapy. The benefits for both patients and health care providers warrant its more widespread use as a normal adjunct to conventional therapy.     

Screening for psychiatric illness with a combined screening and diagnostic instrument

OBJECTIVE: To determine 1) if the PRIME-MD, a two-step screening and diagnostic instrument for psychiatric disorders, increases diagnosis and intervention when actively implemented in a busy general medicine clinic, and 2) the type of staff support required to achieve sufficient implementation to realize gains in diagnosis and treatment. DESIGN: We introduced the PRIME-MD into a large general medicine clinic with repeated rotation of four support conditions for implementation: (1) no support, (2) nonclinical staff support (NCSS), (3) nursing staff (RN) support, and (4) a written "Prompt" condition. SETTING AND PATIENTS: Patients (N = 2,263) attending a general medicine clinic at a Veterans Affairs Medical Center. MEASUREMENTS AND MAIN RESULTS: Outcome measures were (1) PRIME-MD questionnaire and interview use, (2) overall psychiatric diagnosis, (3) new psychiatric diagnosis, and (4) provider intervention for psychiatric conditions. The NCSS, RN support, and prompt conditions resulted in similar rates of questionnaire use but significantly different rates of structured interview use. The NCSS condition was associated with significant increases in new diagnosis, and the RN support and Prompt condition were associated with significant increases in new diagnosis and intervention compared with no support. CONCLUSIONS: Nursing staff support resulted in sufficient PRIME-MD implementation to achieve gains in both new diagnosis and provider intervention compared with no support. These gains occurred in a busy primary care clinic with nonselected providers and customary visit lengths. This level of support should be achievable in most clinical settings.     

Current practices in obstetrical analgesia in German university clinics. Results of a 1996 survey. Part 2

Obviously there is a world-wide trend towards regional analgesia for pain relief during delivery. Data on the current practice in Germany are lacking. METHODS: In 1996 questionnaires on obstetric anaesthesia and analgesia were mailed to all university departments of anaesthesia. RESULTS: All 38 university hospitals with obstetric units replied (100%). Mean annual delivery rate was 1156. Epidural analgesia (EA) (n = 22), intramuscular injection of opioids (n = 18), and non-opioids as a suppository (n = 17) were often used for pain relief during labour. Intravenous injections (n = 12) or pudendus anaesthesia (n = 7) were practised as well. Entonox (N2O/O2), paracervical blocks or transcutaneous electrical stimulation (TENS) was rarely used. EA for relief of labour pain was offered in all university hospitals. Twelve of them had an epidural rate of less than 10%, in nine the rate was 10-19%, in eight hospitals 20-29% and 30% or more in nine. Indication for EA was a demand by the parturient (n = 34), by the obstetrician (n = 26) or the midwife (n = 18), predominantly because of prolonged labour (n = 32) or significant pain (n = 21). Half of the university departments used an epidural combination of local anaesthetics (bupivacaine) and opioids (sufentanil (n = 12) and/or fentanyl (n = 9)). In all but one department the application of an epidural catheter was performed by anaesthesiologists exclusively. In some hospitals obstetricians (n = 10) or midwives (n = 4) were allowed to give epidural top-up injections. Of the 38 university departments 11 had an anaesthesiologists on duty 24 h a day responsible for the obstetric unit exclusively. CONCLUSION: In 1977, 14 of 18 university departments of anaesthesiology offered epidural analgesia for parturients. This option was available in all university departments in 1996. A mean rate of 10-20% epidurals for vaginal delivery is well within the limits reported from other countries, whereas the rate of regional anaesthesia for scheduled caesarean section (40%) still is rather low in Germany, as reported in part 1 of this survey (Anaesthesist 1998;47:59-63).     

Service-learning for graduate students

OBJECTIVES: The European Commission funded EUROTOLD Project sought to examine the legal and ethical implications of living donor organ transplantation within Europe, facilitated by a multi-centre study acquiring data on practices, laws, policies, attitudes and decision-making processes. METHODS: Methods involving primary sources included interviews with clinical staff and past and present organ donors and recipients, and questionnaire surveys of transplant centres, individual clinical staff and legal experts. These strategies were supplemented by an examination of secondary sources such as official reports, transplantation literature, etc. RESULTS: The surveys generated substantial new evidence relating to transplant centre policies and practices, and the attitudes of physicians toward living donation generally and the use of certain specific classes of donor. The latter was facilitated by the use of case scenarios, providing a window upon factors influencing judgments in this sphere. The interview data confirmed earlier findings about donor decision-making. CONCLUSIONS: Responding centres and clinicians displayed a fairly liberal attitude toward living donation but substantial diversity nonetheless exists with regard to living donor transplant volumes between centres and surrounding acceptable waiting times for transplant. Further research is required to identify precisely the reasons underpinning such disparity.     

Determinants of home health visit length: results of a multisite prospective study

OBJECTIVES: The authors (1) compare visit length across four categories of skilled nursing home health visits which reflect recent changes in home health casemix-AIDS-related, hospice/terminal (HT), intravenous (IV) therapy, and maternal and child health (MCH)-with general adult medical/surgical (MS) visits and (2) identify factors influencing visit length. METHODS: The study sites were 12 nonproprietary Massachusetts home health agencies (HHAs). Staff nurses collected data concurrently on a sample of visits they provided between December 1, 1992 and November 30, 1993. The visits were stratified by agency, time of year, and visit category. The authors used analysis of variance to test for significant differences across visit categories in Home Length of Visit (the number of minutes between when the nurse entered and left the home) (HLOV). The authors used multivariate regression analysis to develop models identifying determinants of HLOV and adjusted R2 to measure the explanatory power of partial models. RESULTS: In univariate analysis, the categories differed significantly from each other in length (P < 0.0001). HT visits were the longest (median visit length = 60, 80, and 59 minutes for HT Only visits, visits in both the HT and AIDS categories (HT/AIDS), and HT/IV visits, respectively). MS visits were the shortest (median = 30 minutes). The remaining categories were intermediate in length (medians = 37 to 50 minutes). Almost half the variability in HLOV was explained by the full multivariate regression model, which includes all independent variables (adjusted R2 = .4486; P < 0.0001). Visit characteristics alone in a partial model explained 18% of the variability in HLOV. Three other variable sub-groups-agency, client characteristics, and nursing workload-each explained about 15% of the variability in HLOV. Nursing activities performed during the visit explained 11%; several of these related to teaching, education, or assessment. CONCLUSIONS: Accurate reimbursement reflecting casemix differences is important to protect the teaching, education, and assessment functions of nurses; measure nurse productivity and allocate caseloads; maintain access to services for clients with greater needs; and avoid creating economic disincentives to the agencies that serve them. Payers formulating prospective payment systems can adjust per visit reimbursement rates to reflect differences in visit length by category and incorporate functional limitations, clinical instability, and case coordination as classification variables. Developers of home health casemix systems can use factor analysis to improve the robustness of multivariate models and include nursing workload in predicting visit length. Home health agencies measuring productivity and caseload across complex client populations can classify visits into three groups-MS; HT; and AIDS, IV, and MCH-or use the regression results to develop more refined predictors of visit length and nursing caseload.     

Adverse psychological impact of operative obstetric interventions: a prospective longitudinal study

OBJECTIVE: This paper reports the findings of a prospective longitudinal study of 272 nulliparous pregnant women, which investigated as one of its objectives the psychological sequelae of obstetric procedures. METHOD: Participants completed structured interviews and standardised, published psychometric questionnaires, including the Rosenberg Self-Esteem Scale and the Profile of Mood States late in pregnancy and again early in the postpartum period. RESULTS: Little evidence was found to support the notion that the total number of obstetric interventions was linked to a deterioration in postpartum mood. Significant adverse psychological effects were associated with the mode of delivery. Those women who had spontaneous vaginal deliveries were most likely to experience a marked improvement in mood and an elevation in self-esteem across the late pregnancy to early postpartum interval. In contrast, women who had Caesarean deliveries were significantly more likely to experience a deterioration in mood and a diminution in self-esteem. The group who experienced instrumental intervention in vaginal deliveries fell midway between the other two groups, reporting neither an improvement nor a deterioration in mood and self-esteem. CONCLUSIONS: The findings of this study suggest that operative intervention in first childbirth carries significant psychological risks rendering those who experience these procedures vulnerable to a grief reaction or to posttraumatic distress and depression.     

National Hospital Ambulatory Medical Care Survey: 1992 Emergency Department Summary

OBJECTIVE: This report presents data on the provision and utilization of ambulatory medical care services in hospital emergency departments during 1992. Ambulatory medical care services are described in terms of patient, visit, and facility characteristics. Among these are the patient's reason for the visit, diagnostic and screening services ordered or provided, diagnosis, and medications provided or prescribed. Cause of injury data are presented for injury-related visits. METHODS: Data presented in this report are from the 1992 National Hospital Ambulatory Medical Care Survey (NHAMCS), a national survey of non-Federal, general and short-stay hospitals, conducted by the Division of Health Care Statistics, National Center for Health Statistics, Centers for Disease Control and Prevention. This report reflects the survey's first year of data collection. A four-stage probability sample design was used, resulting in a sample of 524 non-Federal, general and short-stay hospitals. Ninety-two percent of eligible facilities participated in the survey. Hospital staff were asked to complete Patient Record forms for a systematic random sample of patient visits occurring during a randomly assigned 4-week reporting period, and 36,271 forms were completed by participating emergency departments. Diagnosis and cause of injury were coded according to the International Classification of Diseases, 9th Revision, Clinical Modification (ICD-9-CM). Reason for visit and medications were coded according to systems developed by the National Center for Health Statistics. RESULTS: An estimated 89.8 million visits were made to the emergency departments of non-Federal, general and short-stay hospitals in the United States during 1992-357.1 visits per 1,000 persons. Persons 75 years of age and over had a higher visit rate than persons in five other age categories. White persons accounted for 78.5 percent of all visits. However, the visit rate for black persons was significantly higher than for white persons overall and for every age category except 65-74 years and 75 years and over. More than half of all visits were illness related and more than one-third were injury related. Stomach and abdominal pain and chest pain were the most frequently mentioned reasons for visiting the emergency department, accounting for about five million visits each, or 10.7 percent of the total. Accidental falls accounted for the largest share of injury-related visits (22.7 percent).
