Predictive validity of a computerized emergency triage tool.

BACKGROUND: Emergency department (ED) triage prioritizes patients on the basis of the urgency of need for care. eTRIAGE is a Web-based triage decision support tool that is based on the Canadian Triage and Acuity Scale (CTAS), a five level triage system (CTAS 1 = resuscitation, CTAS 5 = nonurgent). OBJECTIVES: To examine the validity of eTRIAGE on the basis of resource utilization and cost as measures of acuity. METHODS: Scores on the CTAS, specialist consultations, computed-tomography use, ED length of stay, ED disposition, and estimated ED and hospital costs (if the patient was subsequently admitted to hospital) were collected for each patient over a six month period. These data were queried from a database that captures all regional ED visits. Correlations between CTAS score and each outcome were measured by using logistic regression models (categorical variables), univariate analysis of variance (continuous variables), and the Kruskal-Wallis analysis of variance (costs). A multivariate regression model that used cost as the outcome was used to identify interaction between the variables presented. RESULTS: Over the six month study, 29,524 patients were triaged by using eTRIAGE. When compared with CTAS level 3, the odds ratios for consultation, CT scan, and admission were significantly higher in CTAS 1 and 2 and were significantly lower in CTAS 4 and 5 (p < 0.001). When compared with CTAS levels 2-5 combined, the odds ratio for death in CTAS 1 was 664.18 (p < 0.001). The length of stay also demonstrated significant correlation with CTAS score (p < 0.001). Costs to the ED and hospital also correlated significantly with increasing acuity (median costs for CTAS levels in Canadian dollars: CTAS 1 = 2,690 dollars, CTAS 2 = 433 dollars, CTAS 3 = 288 dollars, CTAS 4 = 164 dollars, CTAS 5 = 139 dollars, and p < 0.001). Significant interactions between the data collected were found in a multivariate regression model, although CTAS score remained highly associated with costs. CONCLUSIONS: Acuity measured by eTRIAGE demonstrates excellent predictive validity for resource utilization and ED and hospital costs. Future research should focus on specific presenting complaints and targeted resources to more accurately assess eTRIAGE validity.

Characteristics of patients who leave emergency departments without being seen.

OBJECTIVES: Patients leaving the emergency department (ED) without being seen (LWBS) by a physician have become a growing concern in overcrowded EDs. The purpose of this study was to determine the acuity level, reasons, and outcomes of LWBS cases. METHODS: LWBS patients (or their guardians) from two linked Canadian EDs (one adult, one pediatric), identified during 11 sampling periods of seven days' duration each, were contacted by telephone. Descriptive statistics are provided. RESULTS: A total of 711 (4.5%) of 15,660 registered emergency patients left without being seen (50% male; median age, 33 years). Triage-matched controls waited a median of 87 minutes before seeing a physician. Of the 711 LWBS cases, 512 (72%) were contacted and 498 agreed to participate. The most common major reason for leaving was "fed up with waiting" (44.8%). Overall, 60% of LWBS cases sought medical attention within one week; 14 patients were hospitalized, and one required urgent surgery. Triage level was not associated with the probability of subsequently seeking medical attention (61%, 61%, and 60% in triage levels 3, 4, and 5, respectively). Of the 198 (39%) who did not subsequently seek medical attention, 50 patients (26%) had been triaged as urgent and one patient died six days after ED registration. CONCLUSIONS: The most common reason for LWBS is impatience during peak ED periods. Many of these patients seek medical care within one week. Complications occurred rarely; however, "high-risk" patients who leave without being seen do experience adverse health outcomes. Further research is required to examine ways to reduce LWBS cases.

Reviewer agreement trends from four years of electronic submissions of conference abstract.

BACKGROUND: The purpose of this study was to determine the inter-rater agreement between reviewers on the quality of abstract submissions to an annual national scientific meeting (Canadian Association of Emergency Physicians; CAEP) to identify factors associated with low agreement. METHODS: All abstracts were submitted using an on-line system and assessed by three volunteer CAEP reviewers blinded to the abstracts' source. Reviewers used an on-line form specific for each type of study design to score abstracts based on nine criteria, each contributing from two to six points toward the total (maximum 24). The final score was determined to be the mean of the three reviewers' scores using Intraclass Correlation Coefficient (ICC). RESULTS: 495 Abstracts were received electronically during the four-year period, 2001-2004, increasing from 94 abstracts in 2001 to 165 in 2004. The mean score for submitted abstracts over the four years was 14.4 (95% CI: 14.1-14.6). While there was no significant difference between mean total scores over the four years (p = 0.23), the ICC increased from fair (0.36; 95% CI: 0.24-0.49) to moderate (0.59; 95% CI: 0.50-0.68). Reviewers agreed less on individual criteria than on the total score in general, and less on subjective than objective criteria. CONCLUSION: The correlation between reviewers' total scores suggests general recognition of "high quality" and "low quality" abstracts. Criteria based on the presence/absence of objective methodological parameters (i.e., blinding in a controlled clinical trial) resulted in higher inter-rater agreement than the more subjective and opinion-based criteria. In future abstract competitions, defining criteria more objectively so that reviewers can base their responses on empirical evidence may lead to increased consistency of scoring and, presumably, increased fairness to submitters.

Reliability of computerized emergency triage.

OBJECTIVES: Emergency department (ED) triage prioritizes patients based on urgency of care. This study compared agreement between two blinded, independent users of a Web-based triage tool (eTRIAGE) and examined the effects of ED crowding on triage reliability. METHODS: Consecutive patients presenting to a large, urban, tertiary care ED were assessed by the duty triage nurse and an independent study nurse, both using eTRIAGE. Triage score distribution and agreement are reported. The study nurse collected data on ED activity, and agreement during different levels of ED crowding is reported. Two methods of interrater agreement were used: the linear-weighted kappa and quadratic-weighted kappa. RESULTS: A total of 575 patients were assessed over nine weeks, and complete data were available for 569 patients (99.0%). Agreement between the two nurses was moderate if using linear kappa (weighted kappa = 0.52; 95% confidence interval = 0.46 to 0.57) and good if using quadratic kappa (weighted kappa = 0.66; 95% confidence interval = 0.60 to 0.71). ED overcrowding data were available for 353 patients (62.0%). Agreement did not significantly differ with respect to periods of ambulance diversion, number of admitted inpatients occupying stretchers, number of patients in the waiting room, number of patients registered in two hours, or nurse perception of busyness. CONCLUSIONS: This study demonstrated different agreement depending on the method used to calculate interrater reliability. Using the standard methods, it found good agreement between two independent users of a computerized triage tool. The level of agreement was not affected by various measures of ED crowding.

Data collection on patients in emergency departments in Canada.

OBJECTIVE: Relatively little is known about the ability of Canadian emergency departments (EDs) and the federal, provincial and territorial governments to quantify ED activity. The objectives of this study were to determine the use of electronic patient data in Canadian EDs, the accessibility of provincial data on ED visits, and to identify the data elements and current methods of ED information system (EDIS) data collection nationally. METHODS: Surveys were conducted of the following 3 groups: 1) all ED directors of Canadian hospitals located in communities of >10,000 people, 2) all electronic EDIS vendors, and 3) representatives from the ministries of health from 13 provincial and territorial jurisdictions who had knowledge of ED data collection. RESULTS: Of the 243 ED directors contacted, 158 completed the survey (65% response rate) and 39% of those reported using an electronic EDIS. All 11 EDIS vendor representatives responded. Most of the vendors provide a similar package of basic EDIS options, with add-on features. All 13 provincial or territorial government representatives completed the survey. Nine (69%) provinces and territories collect ED data, however the source of this information varies. Five provinces and territories collect triage data, and 3 have a comprehensive, jurisdiction-wide, population-based ED database. Thirty-nine percent of EDs in larger Canadian communities track patients using electronic methods. A variety of EDIS vendor options are available and used in Canada. CONCLUSION: The wide variation in methods and in data collected presents serious barriers to meaningful comparison of ED services across the country. It is little wonder that the majority of information regarding ED overcrowding in Canada is anecdotal, when the collection of this critical health information is so variable. There is an urgent need to place the collection of ED information on the provincial and national agenda and to ensure that the collection of this information consistent, comprehensive and mandatory.

Evaluation of possible tourniquet systems for use in the Canadian Forces.

OBJECTIVE: Hemorrhage from extremity wounds is the leading cause of preventable death on the battlefield. Tourniquets have been identified as the most reasonable option for controlling life threatening extremity hemorrhage in the tactical phase of an operation. The purpose of this trial was to determine which tourniquet systems are effective under simulated combat conditions and make recommendations to the Canadian Forces (CF) on an approach to tourniquet use. METHODS: 5 tourniquet systems were tested: Self Applied Tourniquet System (SATS); One-Handed Tourniquet (OHT); tie & cravat Improvised Tourniquet (IT); pneumatic Emergency Medical Tourniquet (EMT); and latex surgical tubing (ST). On June 25, 2004, ten junior medics from 1 Field Ambulance volunteered for the study. They were divided into five groups of two and rotated through all tourniquets. Each group was timed on the speed of application, and effectiveness of the tourniquets on the lower limbs was determined by a Doppler probe and loss of palpable pulses. Subjective analysis by questionnaire was used to determine ease of use, durability, portability, patient comfort, and preference. RESULTS: Occlusion of the posterior tibial pulse, as measured by Doppler flow, occurred 0-10% of the time with the OHT, 40-50% with the SATS and IT, 70-80% with the EMT, and 90% with the ST. The presence of winter clothing did not change the effectiveness of the tourniquets. The OHT, SATS, IT, and EMT took an average of 30-40 seconds to apply while the ST took only 24 seconds. From most painful to least were: the IT (severe pain-could not tolerate); ST and SATS (moderate-severe pain); OHT (minor-moderate pain); and EMT (no pain-minor discomfort). CONCLUSIONS: The most effective tourniquets were the EMT and ST. The ST is also the lightest, fastest, easiest to learn, and the cheapest but it causes a lot of pain and presumably, local tissue damage. ST can be issued to every soldier with a minimum of training and used effectively in the "Care Under Fire" phase. The EMT, which causes the least pain and is equally effective, can be applied during the "Tactical Field Care" phase by the medic to replace the surgical tubing. Fine adjustments can be made to the EMT, which allows the medic to safely deflate the device, assess the wound, determine if a tourniquet is required, and re-inflate quickly if necessary.

Adjuvant docetaxel for node-positive breast cancer.

BACKGROUND: We compared docetaxel plus doxorubicin and cyclophosphamide (TAC) with fluorouracil plus doxorubicin and cyclophosphamide (FAC) as adjuvant chemotherapy for operable node-positive breast cancer. METHODS: We randomly assigned 1491 women with axillary node-positive breast cancer to six cycles of treatment with either TAC or FAC as adjuvant chemotherapy after surgery. The primary end point was disease-free survival. RESULTS: At a median follow-up of 55 months, the estimated rates of disease-free survival at five years were 75 percent among the 745 patients randomly assigned to receive TAC and 68 percent among the 746 randomly assigned to receive FAC, representing a 28 percent reduction in the risk of relapse (P=0.001) in the TAC group. The estimated rates of overall survival at five years were 87 percent and 81 percent, respectively. Treatment with TAC resulted in a 30 percent reduction in the risk of death (P=0.008). The incidence of grade 3 or 4 neutropenia was 65.5 percent in the TAC group and 49.3 percent in the FAC group (P<0.001); rates of febrile neutropenia were 24.7 percent and 2.5 percent, respectively (P<0.001). Grade 3 or 4 infections occurred in 3.9 percent of the patients who received TAC and 2.2 percent of those who received FAC (P=0.05); no deaths occurred as a result of infection. Two patients in each group died during treatment. Congestive heart failure and acute myeloid leukemia occurred in less than 2 percent of the patients in each group. Quality-of-life scores decreased during chemotherapy but returned to baseline levels after treatment. CONCLUSIONS: Adjuvant chemotherapy with TAC, as compared with FAC, significantly improves the rates of disease-free and overall survival among women with operable node-positive breast cancer.

The incidence of Achilles tendon ruptures in Edmonton, Canada.

BACKGROUND: The incidence of Achilles tendon ruptures specific to the North American population has not been previously reported and current epidemiological data are primarily reported from European communities. The purpose of this study was to determine the incidence of Achilles tendon ruptures in the city of Edmonton, Alberta, Canada, and to compare this data to those reported in European studies. METHODS: A retrospective chart review from all five acute care hospitals in Edmonton from 1998 to 2002 (inclusive) were reviewed for Achilles tendon ruptures. Data such as gender, age, side, mechanism of injury, and season of injury were obtained. RESULTS: The incidence of Achilles tendon ruptures ranged from an annual average of 5.5 ruptures to 9.9 ruptures per 100,000 inhabitants with an overall mean of 8.3 ruptures per 100,000 people. There was a statistically significant difference in Achilles tendon ruptures over the last two study years for both genders (women, p < 0.02; men, p < 0.03). The mean age for an Achilles tendon rupture was 40.6 years for men and 44.5 years for women. The Achilles tendon ruptures occurred most frequently in the 30 to 39 and 40 to 49 year old age groups in both men and women, respectively (p < 0.02). Most ruptures occurred in the spring season, but there was no statistical difference in the incidence of Achilles tendon ruptures by season (p > 0.05). CONCLUSIONS: The incidence of Achilles tendon ruptures in this community was comparable to those reported in European communities (range 6 to 37 ruptures per 100,000 people), although a bimodal age distribution of rupture previously reported was not observed in this study.

Emergency triage: comparing a novel computer triage program with standard triage.

BACKGROUND: Emergency department (ED) triage prioritizes patients based on urgency of care; however, little previous testing of triage tools in a live ED environment has been performed. OBJECTIVES: To determine the agreement between a computer decision tool and memory-based triage. METHODS: Consecutive patients presenting to a large, urban, tertiary care ED were assessed in the usual fashion and by a blinded study nurse using a computerized decision support tool. Triage score distribution and agreement between the two triage methods were reported. A random subset of patients was selected and reviewed by a blinded expert panel as a consensus standard. RESULTS: Over five weeks, 722 ED patients were assessed; complete data were available from 693 (96%) score pairs. Agreement between the two methods was poor (kappa = 0.202; 95% confidence interval [95% CI] = 0.150 to 0.254); however, agreement improved when using weighted kappa (0.360; 95% CI = 0.305 to 0.415) or "within one" level kappa (0.732; 95% CI = 0.644 to 0.821). When compared with the expert panel, the nurse triage scores showed lower agreement (0.263; 95% CI = 0.133 to 0.394) than the tool (kappa = 0.426; 95% CI = 0.289 to 0.564). There was a significant down-triaging of patients when patients were triaged without the computerized tool. Admission rates also differed between the triage systems. CONCLUSIONS: There was significant discrepancy by nurses using memory-based triage when compared with a computer tool. Triage decision support tools can mitigate this drift, which has administrative implications for EDs.

Simple educational intervention to improve the recovery from acute whiplash: results of a randomized, controlled trial.

OBJECTIVES: To determine if an educational intervention in the acute stage of whiplash injury may improve the recovery rate. METHODS: Consecutive subjects were randomized to one of two treatment groups: educational intervention or usual care. The intervention group received an educational pamphlet based on the current evidence. The control group did not receive these materials but received usual emergency department care and a standard nondirected discharge information sheet. Both groups underwent follow-up by telephone interview at two weeks and three months. The primary outcome measure of recovery was the patient's response to the question, "How well do you feel you are recovering from your injuries?" RESULTS: A total of 112 subjects agreed to participate. Age, gender, precollision employment level and health, initial symptoms, collision parameters, and emergency treatments were similar between the groups. At two weeks postcollision, 7.3% in the treatment group reported recovery compared with 8.8% in the control group (absolute risk difference, -1.5%; 95% confidence interval = -12.6% to 9.7%). At three months postcollision, 21.8% in the treatment group reported complete recovery compared with 21.0% in the control group (absolute risk difference, 0.8%; 95% confidence interval = -14.4% to 16.0%). At three months, there were no clinically or statistically significant differences between groups in severity of remaining symptoms, limitations in daily activities, therapy use, medications used, lost time from work, or litigation. CONCLUSIONS: An evidence-based educational pamphlet provided to patients at discharge from the emergency department is no more effective than usual care for patients with grade 1 or 2 whiplash-associated disorder.

The influence of residents training level on their evaluation of clinical teaching faculty.

BACKGROUND: Evaluations by learners are the most common sources of information on teaching. There is some debate about the role of these assessments, but the overall evaluation of faculty by learners was found to be valid and reliable. PURPOSE: The purpose of this study was to examine the relationship between the level of training of family medicine residents and their evaluation of emergency medicine clinical teachers over time. METHODS: A prospective cohort analysis of 6 years of faculty evaluation of 115 teachers was conducted. RESULTS: The 562 residents returned 3,046 valid individual evaluations. There was no significant association between the level of residents' training and the ratings for clinical instruction (p > .05). Resident evaluations did not vary by time of year (p > .05); however, they did significantly differ by year of evaluation, showing that ratings increased over the 6 years of the study (p < .0001). CONCLUSIONS: Neither the residents' level of training nor the timing during the academic year were significant independent predictors of perceived superior teaching performance, although ratings increased over the 6 years of the study.

Aerosolized magnesium sulfate for acute asthma: a systematic review.

BACKGROUND: The use of MgSO(4) is one of numerous treatment options available during exacerbations of asthma. While the efficacy of therapy with IV MgSO(4) has been demonstrated, little is known about inhaled MgSO(4). OBJECTIVES: A systematic review of the literature was performed to examine the effect of inhaled MgSO(4) in the treatment of patients with asthma exacerbations in the emergency department. METHODS: Randomized controlled trials were eligible for inclusion and were identified from the Cochrane Airways Group "Asthma and Wheez*" register, which consists of a combined search of the EMBASE, CENTRAL, MEDLINE, and CINAHL databases and the manual searching of 20 key respiratory journals. Reference lists of published studies were searched, and a review of the gray literature was also performed. Studies were included if patients had been treated with nebulized MgSO(4) alone or in combination with beta(2)-agonists and were compared to the use of beta(2)-agonists alone or with an inactive control substance. Trial selection, data extraction, and methodological quality were assessed by two independent reviewers. The results from fixed-effects models are presented as standardized mean differences (SMDs) for pulmonary functions and the relative risks (RRs) for hospital admission. Both are displayed with their 95% confidence intervals (CIs). RESULTS: Six trials involving 296 patients were included. There was a non-significant increase [corrected] in pulmonary function between patients whose treatments included nebulized MgSO(4) and those whose treatments [corrected] did not (SMD, 0.22; 95% CI, -0.02 to 0.47 [corrected] five studies); there was also a trend toward reduced [corrected] hospitalizations in patients whose treatments included nebulized MgSO(4) (RR, 0.67; 95% CI, 0.41 to 1.09; four studies). Subgroup analyses demonstrated that lung function improvement was similar in adult patients and in those patients who received nebulized MgSO(4) in addition to a beta(2)-agonist. CONCLUSIONS: The use of nebulized MgSO(4), particularly in addition to a beta(2)-agonist, in the treatment of an acute asthma exacerbation appears to produce benefits with respect to improved pulmonary function and may reduce the number of hospital admissions.

The relation between hyperglycemia and outcomes in 2,471 patients admitted to the hospital with community-acquired pneumonia.

OBJECTIVE: To examine whether hyperglycemia at the time of presentation was associated with outcomes in patients admitted to non-intensive care settings with community-acquired pneumonia (CAP). RESEARCH DESIGN AND METHODS: Prospective cohort study of consecutive patients admitted to six hospitals between 15 November 2000 and 14 November 2002. RESULTS: Of the 2,471 patients in this study (median age 75 years), 279 (11%) had serum glucose at presentation >11 mmol/l: 178 of the 401 patients (44%) with a prior diagnosis of diabetes and 101 of the 2,070 patients (5%) without a history of diabetes. Of patients hospitalized with CAP, 9% died and 23% suffered an in-hospital complication. Compared with those with values < or =11 mmol/l, patients with an admission glucose >11 mmol/l had an increased risk of death (13 vs. 9%, P = 0.03) and in-hospital complications (29 vs. 22%, P = 0.01). Compared with those patients with admission glucose < or =6.1 mmol/l, the mortality risk was 73% higher (95% CI 12-168%) and the in-hospital complication risk was 52% higher (12-108%) in patients with admission glucose >11 mmol/l. Even after adjustment for factors in the Pneumonia Severity Index, hyperglycemia on admission remained significantly associated with subsequent adverse outcomes: for each 1-mmol/l increase, risk of in-hospital complications increased 3% (0.2-6%). CONCLUSIONS: Hyperglycemia on admission is independently associated with adverse outcomes in patients with CAP, with the increased risks evident at lower glucose levels than previously reported.

A controlled trial to increase detection and treatment of osteoporosis in older patients with a wrist fracture.

BACKGROUND: Despite the high risk for future fractures and the availability of effective treatments, fewer than 10% to 20% of patients who sustain a fragility fracture are tested or treated for osteoporosis. OBJECTIVES: To improve rates of testing and treatment for osteoporosis in patients with wrist fractures who are seen in the emergency department. DESIGN: Nonrandomized, controlled trial with blinded ascertainment of outcomes. SETTING: Emergency departments in Edmonton, Alberta, Canada. PATIENTS: Persons 50 years of age or older who were treated for a wrist fracture and their physicians. Patients admitted to the hospital or treated for osteoporosis were excluded. Overall, 572 consecutive patients with fractures were screened, and 102 patients (55 intervention, 47 control) and 101 physicians were studied. MEASUREMENTS: The primary end point was the prescription of osteoporosis treatment 6 months after fracture. Secondary end points included rates of testing for bone mineral density and patients' knowledge, satisfaction, and quality of life. INTERVENTION: Faxed physician reminders that contained osteoporosis treatment guidelines endorsed by local opinion leaders and patient education. Control patients received usual care and information about falls and home safety. RESULTS: The median patient age was 66 years. Most patients were female (78%) and white (79%); 70% of patients reported a previous fracture, and 22% had a fall with injury in the previous year. The intervention increased the rates of testing for bone mineral density to 62% (vs. 17% for controls; adjusted relative increase, 3.6 [P < 0.001]) and the rates of osteoporosis treatment to 40% (vs. 10% for controls; adjusted relative increase, 3.8 [P = 0.002]) within 6 months of fracture. Intervention patients were more likely to report a diagnosis of osteoporosis, but other patient-reported outcomes did not differ significantly between groups. LIMITATIONS: This was a small, nonrandomized, controlled study with process-based outcomes. CONCLUSIONS: In a multifaceted intervention directed at patients and their physicians, the rates of testing and treatment for osteoporosis after emergency department care for a fragility fracture were more than 3 times those of controls.

Results of two open-label, multicenter phase II studies of docetaxel, platinum salts, and trastuzumab in HER2-positive advanced breast cancer.

BACKGROUND: Preclinical data indicate that docetaxel, platinum salts, and the combination of both drugs are highly synergistic with the anti-HER2 antibody trastuzumab. The University of California at Los Angeles-Oncology Research Network (UCLA-ORN) and the Breast Cancer International Research Group (BCIRG) have conducted two phase II studies to evaluate docetaxel and trastuzumab in combination with either cisplatin or carboplatin for the treatment of women with advanced breast cancer that overexpresses HER2. METHODS: Each study enrolled 62 patients with HER2-overexpressing tumors. Patients received a median of six cycles of docetaxel at 75 mg/m2 of body surface area and cisplatin (BCIRG 101 study) at 75 mg/m2 or carboplatin (UCLA-ORN study) at AUC = 6 mg/mL. min given on day 1 and then every 21 days. Trastuzumab was given on day 1, cycle 1 (4 mg/kg) and then continued weekly at 2 mg/kg for 1 year or until disease progression. Tumor measurements were obtained at baseline, after three cycles of chemotherapy, and then every 3 months. HER2 gene amplification was determined by fluorescence in situ hybridization. RESULTS: Patient characteristics were comparable between trials with the exception that 15% of the patients in the UCLA-ORN study had received previous adjuvant taxane therapy. Both regimens were well tolerated, with manageable toxicities. Hematologic toxicities were more frequent in patients in the UCLA-ORN study than in patients in the BCIRG 101 study, whereas the reverse pattern was observed for non-hematologic toxicities. One patient in each study developed reversible congestive heart failure. Responses were observed in 49 of 62 patients in the BCIRG 101 study (overall response rate = 79%, 95% confidence interval [CI] = 66% to 89%) and in 34 of 59 evaluable patients in the UCLA-ORN study (overall response rate = 58%, 95% CI = 44% to 70%). Median times to progression were 9.9 months (95% CI = 8.3 to 13.1 months) and 12.7 months (95% CI = 8.6 to 15.5 months) for patients in the BCIRG 101 and UCLA-ORN studies, respectively. Overall response rates were higher and median time to progression was longer in the subset of patients whose tumors harbored HER2 gene amplification. CONCLUSION: Combinations of docetaxel, a platinum salt, and trastuzumab are feasible and active in patients with advanced breast cancers that overexpress HER2. The BCIRG is conducting ongoing randomized studies of the three-drug combination in both the metastatic and adjuvant settings.

Radiologic and patient-reported functional outcomes in an elderly cohort with conservatively treated distal radius fractures.

PURPOSE: There have been few prospective studies of elderly patients with conservatively treated distal radius fractures and little is known about the relationship between acceptable radiographic reduction and functional outcomes in this population. We hypothesized that acceptable fracture reduction (according to standard radiographic dorsal/volar tilt criteria) would be associated with better functional outcomes and greater satisfaction. METHODS: Seventy-four patients who were at least 50 years of age with conservatively managed distal radius fractures were recruited from 2 large urban emergency departments from January 2001 to December 2001. Patients with wrist fractures treated in the emergency department and discharged home were included; patients admitted to the hospital or who required surgical reduction were excluded. Standard lateral radiographs were taken after the final cast was removed. These were reviewed independently by a reference-standard musculoskeletal radiologist and the degree of dorsal/volar tilt was recorded. This value was dichotomized according to standard published dorsal/volar tilt criteria as acceptable (dorsal tilt <10 degrees or volar tilt <20 degrees ) or unacceptable (dorsal tilt >10 degrees or volar tilt >20 degrees ). The Medical Outcomes Study Short-Form 12 (SF-12); the Disabilities of the Arm, Shoulder, and Hand questionnaire; and a patient satisfaction survey were used to assess patient-reported outcomes 6 months after the injury. RESULTS: The average dorsal/volar tilt measured by the reference standard radiologist was 3.4 degrees (SD=13.6) dorsal; overall 47 patients (64%) were considered to have an acceptable radiographic reduction. Acceptable radiographic reduction was not associated with better generic physical or mental health status, lesser degrees of upper-extremity disability, or greater satisfaction with outcomes than was unacceptable reduction. Overall 44 of 74 patients (59%) reported being satisfied or very satisfied with their functional status at 6 months. CONCLUSIONS: Contrary to our hypotheses we found that acceptable radiographic reduction (according to dorsal/volar tilt criteria) was not associated with better self-reported functional outcomes or increased satisfaction at 6 months in elderly patients with conservatively treated distal radius fractures.
