[Fewer caesarean sections for breech presentation following external cephalic version according to a protocol in a special office visit]. / Minder keizersneden wegens stuitligging dankzij geprotocolleerde uitwendige versie in een speciaal spreekuur.

OBJECTIVE: Identification of determinants affecting the outcome of external cephalic version (ECV) in breech presentation, and investigation of the impact of ECV--performed according to a standardized protocol in an outpatient clinic--on the mode of delivery. DESIGN: Retrospective analysis. METHOD: In 2003 a standardized protocol of ECV was developed in the outpatient clinic for obstetrics of the Catharina Hospital in Eindhoven, the Netherlands; it was tested in 'version office visits'. Obstetric characteristics of all pregnant women who underwent attempts of ECV in the clinic from January 2004 until June 2006 during these sessions, and the subsequent births, were analysed. 85% of all ECVs were performed by the same hospital midwife and gynaecologist, in accordance with the protocol. RESULTS: ECV was successful in 96 of 209 pregnant women (46%). In 1 pregnant woman an emergency caesarean section was performed after ECV because of partial abruptio placentae. Nulliparity, incomplete breech presentation and low birth weight of the baby were associated with a lower success rate of ECV in this study. In the group with a successful ECV the percentage of caesarean deliveries was substantially lower (9 versus 83%; odds ratio: 0.21; 95% CI: 0.09-0.51). CONCLUSION: A regular team consisting of a hospital midwife and a gynaecologist working according to a standardized protocol for ECV in a case of breech presentation proved successful: the number of term breech presentations substantially diminished and therefore the percentage of caesarean sections was lower in the group in which ECV had been successful. This could have considerable impact on health care in the Netherlands in terms of reduced maternal morbidity and cost savings.

Alcohol expectancies as a mediator of the relationship between injury and readiness to change drinking behavior.

There is a well-established relationship between alcohol expectancies and drinking behavior. The purpose of the present study was to extend the literature by examining the role of alcohol expectancies in determining readiness to change drinking behavior among injured emergency department patients who screened positive for hazardous drinking. Negative expectancies were found to partially mediate the relationships of alcohol-related injuries and injury aversiveness to readiness to change drinking behavior. Results suggest that negative alcohol expectancies are a potential means of increasing patients' readiness to change drinking behavior.

Mothers with histories of domestic violence in a pediatric emergency department.

OBJECTIVE: To determine the prevalence of domestic violence against mothers in a pediatric emergency department and the relationship of their children to the abusers. DESIGN: Cross-sectional survey of a convenience sample of mothers seeking treatment for their children. SETTING: An urban pediatric emergency department. PARTICIPANTS: A total of 157 mothers with children <3 years of age. Women were excluded if older children or partners were present. RESULTS: A total of 52% of women reported histories of adult physical abuse, 21% reported adult sexual abuse, and 28% reported childhood sexual abuse. A total of 10% of women were in abusive relationships in the past year. Victims of adult physical abuse were more likely to report histories of adult sexual abuse (relative risk [RR]: 4.93) or childhood sexual abuse (RR: 3.13). Intimate partners perpetrated 67% of physical abuse and 55% of sexual abuse. Relatives perpetrated 66% of childhood sexual abuse. Women who revealed histories of childhood sexual abuse were more likely to report adult sexual abuse (RR: 4. 93). A total of 40% of the perpetrators of adult physical abuse, 73% of the perpetrators of past year physical abuse, and 10% of the perpetrators of adult sexual abuse had regular contact with their victims' children. Health care providers screened only 21% of the women for past violence. Victims of domestic violence were no more likely to have been screened than those without histories of physical or sexual abuse. CONCLUSIONS: Mothers of young patients in a pediatric emergency department are often victims of domestic violence. Perpetrators are often close relatives and thus place the victims' children at risk for abuse and for the psychological trauma of witnessing violence. Given the prevalence of domestic violence, families may benefit from routine violence screening and interventions in pediatric emergency departments.

Emergency medical services in the reconstruction phase following a major earthquake: a case study of the 1988 Armenia earthquake.

STUDY OBJECTIVE: To use the clinical activities of an ambulance service as a tool to assess the residual and unmet medical needs of a city in the aftermath of a major earthquake and to apply that assessment to the development of a training curriculum for the prehospital personnel. METHODS: The researchers conducted structured interviews with health care workers at all levels of the emergency health care delivery system in Gyumrii, Armenia, and carried out a retrospective frequency analysis of 29,010 ambulance runs for an 11-month period from February through December 1992. Runs first were assigned into the broad categories of: 1) Adult Medical; 2) Pediatric Medical; or 3) Trauma, and then, according to diagnosis. The runs then were classified further as: 1) Primary Care; 2) Basic Life Support (BLS); or 3) Advanced Life Support (ALS). RESULTS: Adult Medical calls represented 24,684 (85%), Pediatric Medical calls 459 (1.6%), and Trauma calls 3,867 (13%). Only 12% of all ambulance calls resulted in transport to a medical facility, although this percentage was higher in children. Thirty percent of Adult Medical patients were diagnosed by the emergency medical providers as having exclusively a psychiatric problem. CONCLUSION: In the late aftermath of a devastating earthquake, the ambulance service in Gyumrii, Armenia has been delivering a substantial proportion of non-emergency, primary care services. They have adopted this unconventional role to compensate for the deficit in health care facilities and personnel created by the disaster. The training program that the investigators developed reflected the actual work activities of the prehospital personnel demonstrated in their assessment.

Analysis of alcohol use clusters among subcritically injured emergency department patients.

OBJECTIVES: 1) To cluster patients according to self-reported drinking patterns using cluster analysis; 2) to externally validate clustered groups on variables related to drinking but not used in the cluster analysis; and 3) to use the clustered patients' responses to alcohol consumption questions to develop a brief screening tool emergency physicians can use to identify patients in need of referral or intervention related to potentially hazardous alcohol consumption. METHODS: A self-report battery was administered to 95 subcritically injured patients. Patients also were saliva alcohol-tested upon arrival to the ED. Using the patients' self-reported quantity, frequency of alcohol consumption, and frequency of having > or = 6 drinks on a drinking occasion, patients were categorized into 3 groups using cluster analysis. The 3 clusters were externally validated using injury-related variables, alcohol-related consequences, and the patients' reported readiness to change drinking. A screening tool was developed using cutoff values reported by the patients' answers to drinking pattern questions. RESULTS: Fifty-nine patients were alcohol-negative, and 36 tested alcohol-positive (i.e., > 4 mmol/L [> 20 mg/dL]) or had elevated scores on an alcohol problem screening instrument. Three distinct drinking pattern clusters were found. Clusters were validated using discriminant function analysis and multivariate analyses of variance to confirm cluster classifications. Steady and high-intensity drinkers reported more alcohol-related negative consequences, and high-intensity drinkers indicated they would consider changing their drinking. The screening tool correctly classified 97% of the patient sample into their respective clusters. CONCLUSIONS: Using the drinking pattern questions in the clustering procedure was effective for grouping injured patients into clusters that could be differentiated on other drinking-related variables. The resulting screening tool can be used in the ED setting to screen patients for further assessment and intervention. The readiness-to-change results support the assertion that the injury event provides a "teachable moment" for subcritically injured patients whose injury may be related to their alcohol consumption.

Factors and methodology in achieving ideal delivery temperatures for intravenous and lavage fluid in hypothermia.

A study was undertaken to determine the relationship between temperature and delivery rate of warmed intravenous fluid using standard intravenous infusion equipment and tubing. One-liter bags of 0.9% NaCl were warmed to 60 degrees C and run through standard microdrip tubing for 1 hour at rates of 1,000, 800, 600, and 400 mL/h. Thermistor probes were placed into the bag and into the tubing at 0, 100, 180, 230, and 280 cm from the intravenous bag. Separate fluid bags were also warmed to 39.3 degrees and 75 degrees C, and the fluid was run through the same apparatus at 1,000 mL/h and 200 mL/h, respectively. Temperatures were recorded at each site at the start of the infusion and every 10 minutes thereafter for 1 hour, Subsequently, 60-mL syringes of fluid warmed to 39.5 degrees C were eluted through 50 cm tubing over 10 minutes at 300 mL/h and 360 mL/h. Mean delivery temperature over each 10-minute infusion was determined. Fluid preheated to 39.3 degrees C approached room temperature at delivery even at a flow rate of 1,000 mL/h and tubing lengths as short as 100 cm. Fluid preheated to 60 degrees C was delivered at near 37 degrees C using tubing lengths as long as 280 cm when eluted at 1,000 mL/h. Fluid preheated to 39 degrees C in 60-mL syringes and eluted through 50 cm of tubing over a period of 10 minutes at 300 mL/h or 360 mL/h was delivered near a mean temperature of 37 degrees C. These results show that warmed fluid can be delivered through standard intravenous tubing at or near 37 degrees C if the fluid is preheated to 60 degrees C and eluted through long tubing (280 cm) at high flow rates (1,000 mL/h). Alternatively, fluid warmed to 37 degrees C to 42 degrees C can be delivered at or near 37 degrees C via intermittent bolus through short tubing (50 cm) either by hand or syringe pump. The latter approach would be particularly beneficial in the pediatric population, in whom it is not advisable to administer fluid at flow rates as high as 1,000 mL/h.

Violence against women: provider barriers to intervention in emergency departments.

OBJECTIVE: To determine: 1) provider behavior in screening for domestic violence (DV) and sexual assault (SA); 2) provider training in DV and SA; 3) provider knowledge of available protocols for DV and SA; and 4) provider perception of barriers to intervention. METHODS: Anonymous, structured surveys were distributed to physicians, nurses, and social workers at an adult ED trauma center, an affiliated pediatric ED, and a women's urgent care center between July and September 1995. RESULTS: Of 207 staff members (59%) responding, 54% and 68% indicated that they never/rarely screen for DV or SA, respectively. Thirty-five percent had received no DV training and 27% had received no SA training. Thirty-one percent of the staff had knowledge of existing protocols for DV and 63% had knowledge of existing protocols for SA. Providers trained in DV were more likely to screen for DV (RR 1.5, 95% CI 1.27-1.92, p < or = 0.001) and SA (RR 1.49, 95% CI 1.24-1.79, p < or = 0.0018), and providers trained in SA were more likely to screen for SA (RR 1.32, 95% CI 1.13-1.54, p = 0.0019) and DV (RR 1.35, 95% CI 1.13-1.60, p = 0.0007). Barriers that the majority of staff experienced in the care of DV/SA victims included: frustration that the victim would return to an abusive partner, concerns about misdiagnosis, lack of time, personal discomfort, reluctance to intrude into familial privacy, and lack of 24-hour social service support. CONCLUSION: Providers surveyed had received little training in and rarely screen for violence, and there are a range of personal and institutional barriers impeding intervention with victims of SA and DV. Institutional changes to enhance training and support providers working in the front line of this epidemic may improve services for victims of violence.

Health care personnel in disaster response. Reversible roles or territorial imperatives?

Disasters frequently demand exceptional skills from medical responders. Providers work most efficiently and effectively, however, within the roles and hierarchical structures with which they are familiar. The goal of disaster medical response planners is to assign personnel to roles that are as familiar as possible and to simultaneously enhance flexibility of response to extraordinary circumstances. We have outlined the most common disaster medical response roles and the personnel types that fit most directly as a primary provider within each role. Medics excel in field operations and field care of patients, whereas the training of nurses and physicians makes them the most flexible all-around providers, if specially trained in field emergency care, and the sole providers of definitive care. None of the providers, by virtue of their basic training, is well equipped to manage the public health consequences of disasters, but nurses and physicians should be able to easily move into the role, given appropriate special training. Some of the special courses needed to make medics, nurses, and physicians capable of serving flexible roles already exist; others need to be developed or enhanced.

Use of infrared thermometry to measure lavage and intravenous fluid temperature.

A study was conducted to determine the accuracy of tympanic thermometers for measuring the temperature of warmed fluids in fluid bags and in tubing at the delivery site (ie, beside the intravenous [IV] catheter). One-liter 0.9% saline bags were warmed in a microwave oven. A thermocouple electronic temperature probe was then used to measure the reference temperature. The probe was inserted into each bag and bathed in the fluid. Temperature changes were recorded simultaneously over a 20-minute period using the probe and a First Temp Tympanic Thermometer (Intelligent Medical Systems, Inc, Carlsbad, CA). The warmed fluid was then allowed to run through microdrip IV tubing. Temperature of the effluent was measured in the tubing using the tympanic thermometer externally and the probe internally at the same point. The two measures were compared using linear regression and Student's t tests. Overall, the correlation between the two probes was r = 0.99 for both the fluid bags and the IV tubing. The overall mean differences were small, 0.7 degrees C and 1.2 degrees C for the bags and tubing, respectively, but they were statistically different (P > .05). Data were analyzed in three temperature ranges: < 36 degrees C, 36 degrees C to 41 degrees C, and 41 degrees C. Again, small differences were found on the order of 1 degree C. It was concluded that infrared thermometry is an accurate method for measuring the initial and delivery temperature of warmed fluids. Although tympanic thermometer measurements were statistically different from reference readings in certain temperature ranges, these differences were small and not clinically significant.(ABSTRACT TRUNCATED AT 250 WORDS)

Effect of auxiliary prescription labels on the elderly ambulatory patient's drug knowledge.

The elderly take more drugs per capita than younger age groups. As a result, they may require more drug information. Auxiliary prescription labels are a common, yet little studied method of providing drug information. We studied 4 groups of 20 patients aged 65 or older, who obtain prescriptions at community pharmacies. They received either auxiliary label(s), counseling, both counseling and auxiliary labels, or no supplementary information at all. Counseling provided the same information verbally as was provided on the labels. Patients were interviewed 3-15 days later. Sixty-six percent were able to read auxiliary labels without difficulty. Significantly more patients who received auxiliary labels, with counseling (65 percent) or without counseling (63 percent), were able to recall supplementary information correctly and completely compared with patients who did not receive supplementary information (25 percent). However, a significant improvement in understanding or ability to apply this information was not found. Counseling alone did not significantly improve either outcome. It was concluded that the use of auxiliary labels is a useful, although not ideal, method of providing drug information for elderly patients in a busy community pharmacy setting.
