Longitudinal evaluation of pediatric respiratory infections.

OBJECTIVE: Acute respiratory infections are the most common cause of under-five-year-old pediatric mortality worldwide. Due to a paucity of data, the impact of many respiratory viruses and their association with respiratory failure in children are unclear. We assessed single respiratory viral pathogens and their association with intubation, and secondly describe dual viral pathogens and viral-bacterial pathogens associations with intubation. PATIENT AND METHODS: This was a retrospective cross-sectional study of children (0-18 years old) admitted to the acute care unit and/or pediatric intensive care unit of an urban, quaternary children's hospital from November 1, 2013 to November 1, 2017. Patients with viral studies sent within 48 h of admission were included. Associations of viral pathogens and intubation status were calculated using odds ratios (OR), 95% confidence intervals (CI) and p-values. RESULTS: There were 15,923 hospitalization encounters, with 634 (3.9%) requiring intubation. RSV and hMPV had increased odds for intubation, (aOR 1.80, 95% CI 1.50-2.18) and (aOR 1.59, 95% CI 1.13-2.24) respectively. Coinfection with RSV and adenovirus had increased odds of requiring intubation, (aOR 3.48, 95% CI 1.21-10.01). Contrary, coinfection with influenza A and RSV had no intubations. In the viral-bacterial coinfections model, there was an increased association with intubations for RSV and Streptococcus (aOR 9.34, 95% CI 4.21-20.71) and hMPV and Streptococcus (aOR 8.98, 95% CI 1.62-49.88). CONCLUSION: RSV and hMPV corresponded to the highest rates of intubations, and dual infections with RSV and adenovirus, RSV and Streptococcus, and hMPV and Streptococcus were associated with mechanical ventilation, revealing differences amongst the groups.

Evaluation of Hydrocodone/Acetaminophen for Pediatric Laceration Repair: A Randomized Trial.

BACKGROUND: Laceration repair is a common procedure, and causes pain and distress in children. The purpose of this study was to measure the effect of hydrocodone/acetaminophen elixir in reducing both pain and anxiety in children undergoing sutured laceration repair in the emergency department. METHODS: The authors conducted a randomized, double-blinded, placebo-controlled trial in children aged 2 to 17 years, stratified by age younger than 8 years, with topical lidocaine-treated lacerations requiring sutured repair in the emergency department. The primary outcome was pain score at 5 minutes of laceration repair. Secondary outcomes included progression to procedural sedation and anxiety scores in older children. RESULTS: Eighty-five children were randomized, 43 to the hydrocodone/acetaminophen group and 42 to the placebo group. Median 5-minute pain scores in children aged 2 to 7 years were significantly lower in the medication group (5.0; interquartile range, 4.0 to 6.50) compared with the placebo group (7.0; interquartile range, 5.25 to 10.0; p = 0.01). Three patients (12 percent) in the placebo group proceeded to procedural sedation. For children aged 8 to 17 years, there was no significant difference in pain scores between the treatment (0.5; interquartile range, 0.0 to 0.1; p = 0.81) and placebo groups (0.1; interquartile range, 0.01 to 0.4) or in anxiety scores using the State-Trait Anxiety Inventory for Children. CONCLUSION: Adjuvant oral hydrocodone/acetaminophen is more effective than placebo in reducing pain in children younger than 8 years undergoing topical lidocaine-treated laceration repair, but it does not decrease pain or anxiety in older children. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, II.

Shortened preprocedural fasting in the pediatric emergency department.

BACKGROUND: There is no evidence of an association between fasting time and the incidence of adverse events during procedural sedation and analgesia. Pediatric and adult emergency medicine guidelines support avoiding delaying procedures based on fasting time. General pediatric guidelines outside emergent care settings continue to be vague and do not support a set fasting period for urgent and emergent procedures. OBJECTIVE: To describe shortened preprocedural fasting and vomiting event rates during the implementation of a shortened fasting protocol. METHODS: This was a prospective study of patients undergoing procedural sedation and analgesia (PSA) in an urban, tertiary care children's hospital emergency center from March 2010-February 2012. All consecutive patients had documentation of preprocedural fasting time and adverse events recorded on a standardized data collection form. RESULTS: PSA occurred in 2426 patients with fasting data available for 2188 (90.2%); 1472 were fasted ≥6 h for solids and 716 patients were in the shortened fasting group (<6 h). There is no evidence of an association between emesis at any time and shortened fasting time unadjusted (OR = 1.18 (95% CI 0.75-1.84) or adjusted for known risk factors including age >12 years, initial ketamine dose >2.5 mg/kg or total dose >5.0 mg/kg (OR = 1.14 (95% CI 0.74-1.75). CONCLUSION: Analysis of a large prospective cohort study failed to find evidence of an association between emesis and shortened fasting time upon implementation of a shortened fasting protocol for procedural sedation and analgesia.

Characteristics and outcomes of acute pediatric blunt torso trauma based on injury intent.

INTRODUCTION: Blunt trauma is a leading cause of pediatric morbidity. We compared injuries, interventions and outcomes of acute pediatric blunt torso trauma based on intent. METHODS: We analyzed de-identified data from a prospective, multi-center emergency department (ED)-based observational cohort of children under age eighteen. Injuries were classified based on intent (unintentional/inflicted). We compared demographic, physical and laboratory findings, ED disposition, hospitalization, need for surgery, 30-day mortality, and cause of death between groups using Chi-squared or Fisher's test for categorical variables, and Mann-Whitney test for non-normal continuous factors comparing median values and interquartile ranges (IQR). RESULTS: There were 12,044 children who sustained blunt torso trauma: Inflicted=720 (6%); Unintentional=9563 (79.4%); Indeterminate=148 (1.2%); Missing=1613 (13.4%). Patients with unintentional torso injuries significantly differed from those with inflicted injuries in median age in years (IQR) [10 (5, 15) vs. 14 (8, 16); p-value<0.001], race, presence of pelvic fractures, hospitalization and need for non-abdominal surgery. Mortality rates did not differ based on intent. Further adjustment using binary, logistic regression revealed that the risk of pelvic fractures in the inflicted group was 96% less than the unintentional group (OR: 0.04; 95%CI: 0.01-0.26; p-value=0.001). CONCLUSIONS: Children who sustain acute blunt torso trauma due to unintentional causes have a significantly higher risk of pelvic fractures and are more likely to be hospitalized compared to those with inflicted injuries.

Factors influencing drainage setting and cost for cutaneous abscesses among pediatric patients.

OBJECTIVE: To evaluate the clinical and microbiological factors associated with skin and soft tissue infections drained in the emergency department (ED) vs operative drainage (OD) in a tertiary care children's hospital. METHODS: This was a cross-sectional study among children aged 2 months to 17 years who required incision and drainage (I&D). Demographic information, signs and symptoms, abscess size and location, and wound culture/susceptibility were recorded. Patient-specific charges were collected from the billing database. Multivariate regression analysis was used to determine factors determining setting for I&D and the effect of abscess drainage location on cost. RESULTS: Of 335 abscesses, 241 (71.9%) were drained in the ED. OD for abscesses was favored in children with prior history of abscess (odds ratio [OR], 3.18; 95% confidence interval [CI], 1.36-7.44; P = .01) and labial location (OR, 37.81; 95% CI, 8.12-176.03; P < .001). For every 1-cm increase in size, there was approximately a 26% increase in the odds of having OD (OR, 1.26; 95% CI, 1.11-1.44, P < .001). Methicillin-resistant Staphylococcus aureus was identified in 72% of the 300 abscesses cultured and 12.3% were clindamycin resistant. OD was more expensive than I&D in the ED. Per abscess that underwent I&D, OD is $3804.29 more expensive than I&D in the ED while controlling for length of stay. DISCUSSION: Clinical factors associated with OD rather than I&D in the ED included history of abscess, increased abscess length, and labial location. Microbiological factors did not differ based on I&D setting. For smaller, nonlabial abscesses, ED drainage may result in significant cost savings.

Factors associated with a lack of pap smear utilization in women exposed in utero to diethylstilbestrol.

BACKGROUND: Women in the 1940s-1960s were prescribed diethylstilbestrol (DES), a nonsteroidal estrogen, to prevent miscarriages, but the practice was terminated after it was discovered that the daughters so exposed in utero were at increased risk for developing clear cell adenocarcinoma (CCA) of the vagina or cervix at early ages. Pap smear screening is one of the principal methods used to identify tumor development and is necessary in this group of women to maintain their health. Currently, little is known about the factors associated with nonutilization of this screening tool in this high-risk population of women. METHODS: National cohort data from the National Cancer Institute (NCI) DES Combined Cohort Follow-up Study during 1994, 1997, 2001, and 2006 were used to determine which factors were associated with Pap smear screening nonutilization in 2006 among DES-exposed and unexposed women. Self-reported questionnaire data from 2,861 DES-exposed and 1,027 unexposed women were analyzed using binary logistic regression models. RESULTS: DES exposure, not having a previous gynecologic dysplasia diagnosis, lack of insurance, originating cohort, increasing age, and previous screening behavior were all factors associated with not reporting a Pap smear examination in the 2006 questionnaire, although college education reduced nonutilization. CONCLUSIONS: Understanding which factors are associated with not acquiring a screening exam can help clinicians better identify which DES-exposed women are at risk for nonutilization and possibly tailor their standard of care to aid in the early detection of cervical and vaginal adenocarcinomas in this high-risk group.

Damage-control resuscitation increases successful nonoperative management rates and survival after severe blunt liver injury.

BACKGROUND: Nonoperative multidisciplinary management for severe (American Association for the Surgery of Trauma Grades IV and V) liver injury has been used for two decades. We have previously shown that Damage Control Resuscitation (DCR) using low-volume, balanced resuscitation improves survival of severely injured trauma patients; however, little attention has been paid to organ-specific outcomes. We wanted to determine if implementation of DCR has improved survival and successful nonoperative management after severe blunt liver injury. METHODS: A retrospective study was performed on all adult trauma patients with severe blunt liver injury who were admitted from 2005 to 2011. Patients were divided into pre-DCR (2005-2008) and DCR (2009-2011) groups. Patients who died before leaving the emergency department (ED) were excluded. Outcomes (resuscitation products used, survival, and length of stay) were then compared by univariate and multivariate analyses. RESULTS: Between 2005 and 2011, 29,801 adult trauma patients were admitted, and 1,412 (4.7%) experienced blunt liver injury. Of these, 244 (17%) sustained Grade IV and V injuries, with 206 patients surviving to leave the ED. The pre-DCR group (2005-2008) was composed of 108 patients, and the DCR group (2009-2011) had 98 patients. The groups were not different in demographics as well as prehospital and ED vital signs or Injury Severity Score (ISS). No change in operative or interventional radiology techniques occurred in this time frame. The DCR cohort had an increase in successful nonoperative management (from 54% to 74%, p < 0.01) as well as a reduction in initial 24-hour packed red blood cell (median, from 13 U to 6.5 U; p < 0.01), plasma (median, from 13 U to 8 U; p < 0.01), and crystalloid (median, from 5,800 mL to 4,100 mL; p < 0.01) administration. The DCR treatment was associated with improved survival, from 73% to 94% (p < 0.01). CONCLUSION: In patients with severe blunt liver injury, DCR was associated with less crystalloid and blood product use, a higher successful nonoperative management rate, and improved survival. Resuscitation technique may improve outcomes after severe liver injury. LEVEL OF EVIDENCE: Therapeutic/care management, level III.

Early surgical intervention for blunt bowel injury: the Bowel Injury Prediction Score (BIPS).

BACKGROUND: Computed tomography (CT) scan of the abdomen has been used for 30 years to evaluate the stable blunt trauma patient. However, the early diagnosis of blunt hollow viscus injury (BHVI) remains a challenge. Delayed diagnosis and intervention of BHVI lead to significant morbidity and mortality. This study aimed to identify a combination of radiographic and clinical variables present at admission that could lead to earlier surgical intervention for BHVI. METHODS: Significant predictors were identified through a retrospective review of all blunt trauma patients admitted to a Level 1 trauma center from 2005 to 2010 with an admission CT of the abdomen/pelvis and diagnosed with any mesenteric injury. The Bowel Injury Prediction Score (BIPS) was calculated based on the following three elements with a point given for each outcome: white blood cell count of 17.0 or greater, abdominal tenderness, and CT scan grade for mesenteric injury of 4 or higher. RESULTS: A total of 18,927 blunt trauma patients were admitted during the study period. Of these, 380 had a mesenteric injury, 110 met inclusion criteria, 60 had a surgical intervention, and 43 had BHVI. Of the 110 study patients, 43 (39%) had an immediate operation, 17 (16%) had a delayed operation (>4 hours), and 50 (46%) had no surgical intervention. The median BIPS for the immediate and delayed group was 2, while for the no-surgery group, the score was 0. Patients with a BIPS of 2 or greater were 19 times more likely to have a BHVI than patients with a BIPS of less than 2 (odds ratio, 19.2; 95% confidence interval, 6.78-54.36; p < 0.001). CONCLUSION: Three predictors (admission CT scan grade of mesenteric injury, white blood cell count, and abdominal tenderness) were used to create a new bowel injury score, with a score of 2 or greater being strongly associated with BHVI. Prospective validation of these retrospective findings is warranted to fully assess the accuracy of the BIPS. LEVEL OF EVIDENCE: Prognostic study, level III.

Hypercoagulability after injury in premenopausal females: a prospective, multicenter study.

BACKGROUND: Recent studies suggest there are gender-specific differences in injury response that may be related to coagulation. The objective of this study was to test the hypothesis that rapid thrombelastography (rTEG) coagulation profiles differ by gender. METHODS: Adult trauma patients were prospectively followed at 3 level 1 trauma centers over a 14-month period. rTEG was obtained upon arrival and serially at several time points during the hospital stay. Female patients were stratified into premenopausal (≤50 years) and postmenopausal (>50 years) age groups with age-matched male cohorts. Values were analyzed using a repeated-measures multilevel linear model to evaluate the effect of gender on coagulation. RESULTS: A total of 795 patients had serial rTEG data (24% female and 76% male). Compared with age-matched males, premenopausal females were more hypercoagulable by rTEG on admission (P < .001) and for the first 12 hours after arrival. Gender was an effect modifier for alpha angle (P = .02) and maximum amplitude (P = .04). Controlling for Injury Severity Score and mechanism of injury, age-matched males had a >4-fold increased risk of hypercoagulable complications than premenopausal females (odds ratio, 4.7; P = .038). CONCLUSION: This prospective, multicenter study demonstrates that premenopausal females are relatively hypercoagulable compared with age-matched males early after injury. However, this did not translate into higher thromboembolic complications.

Evaluation of noninvasive hemoglobin measurements in trauma patients.

BACKGROUND: Reliable, accurate, noninvasive, and continuous determination of hemoglobin would be an important advance in the care of trauma patients. The aim of this study was to evaluate the utility of the Masimo Radical 7 device in severely injured trauma patients. METHODS: Highest level trauma activation patients were enrolled over a 1-year period. Laboratory hemoglobin values were compared with Masimo hemoglobin values using Bland-Altman analysis. RESULTS: A total of 525 patients were enrolled in the study. Comparison of 861 paired values from 418 patients showed a variance of 3.89 to -3.84 g/dL, showing a nonsignificant correlation between Masimo hemoglobin and laboratory hemoglobin values. CONCLUSIONS: The Masimo Radical 7 system evaluated in this study holds promise, but it is not ready to be used as an initial noninvasive evaluation tool in the acute treatment of severely injured trauma patients. There was a poor correlation between Masimo hemoglobin and laboratory hemoglobin and large numbers of missing data. On the basis of the poor correlation, the Masimo Radical 7 device cannot currently be used to guide transfusion therapy.

A randomized controlled pilot trial of modified whole blood versus component therapy in severely injured patients requiring large volume transfusions.

OBJECTIVES: To determine whether resuscitation of severely injured patients with modified whole blood (mWB) resulted in fewer overall transfusions compared with component (COMP) therapy. BACKGROUND: For decades, whole blood (WB) was the primary product for resuscitating patients in hemorrhagic shock. After dramatic advances in blood banking in the 1970s, blood donor centers began supplying hospitals with individual components [red blood cell (RBC), plasma, platelets] and removed WB as an available product. However, no studies of efficacy or hemostatic potential in trauma patients were performed before doing so. METHODS: Single-center, randomized trial of severely injured patients predicted to large transfusion volume. Pregnant patients, prisoners, those younger than 18 years or with more than 20% total body surface area burns (TBSA) burns were excluded. Patients were randomized to mWB (1 U mWB) or COMP therapy (1 U RBC+ 1 U plasma) immediately on arrival. Each group also received 1 U platelets (apheresis or prepooled random donor) for every 6 U of mWB or 6 U of RBC + 6 U plasma. The study was performed under the Exception From Informed Consent (Food and Drug Administration 21 code of federal regulations [CFR] 50.24). Primary outcome was 24-hour transfusion volumes. RESULTS: A total of 107 patients were randomized (55 mWB, 52 COMP therapy) over 14 months. There were no differences in demographics, arrival vitals or laboratory values, injury severity, or mechanism. Transfusions were similar between groups (intent-to-treat analysis). However, when excluding patients with severe brain injury (sensitivity analysis), WB group received less 24-hour RBC (median 3 vs 6, P = 0.02), plasma (4 vs 6, P = 0.02), platelets (0 vs 3, P = 0.09), and total products (11 vs 16, P = 0.02). CONCLUSIONS: Compared with COMP therapy, WB did not reduce transfusion volumes in severely injured patients predicted to receive massive transfusion. However, in the sensitivity analysis (patients without severe brain injuries), use of mWB significantly reduced transfusion volumes, achieving the prespecified endpoint of this initial pilot study.

Seven deadly sins in trauma outcomes research: an epidemiologic post mortem for major causes of bias.

BACKGROUND: Because randomized clinical trials in trauma outcomes research are expensive and complex, they have rarely been the basis for the clinical care of trauma patients. Most published findings are derived from retrospective and occasionally prospective observational studies that may be particularly susceptible to bias. The sources of bias include some common to other clinical domains, such as heterogeneous patient populations with competing and interdependent short- and long-term outcomes. Other sources of bias are unique to trauma, such as rapidly changing multisystem responses to injury that necessitate highly dynamic treatment regimens such as blood product transfusion. The standard research design and analysis strategies applied in published observational studies are often inadequate to address these biases. METHODS: Drawing on recent experience in the design, data collection, monitoring, and analysis of the 10-site observational PRospective Observational Multicenter Major Trauma Transfusion (PROMMTT) study, 7 common and sometimes overlapping biases are described through examples and resolution strategies. RESULTS: Sources of bias in trauma research include ignoring (1) variation in patients' indications for treatment (indication bias), (2) the dependency of intervention delivery on patient survival (survival bias), (3) time-varying treatment, (4) time-dependent confounding, (5) nonuniform intervention effects over time, (6) nonrandom missing data mechanisms, and (7) imperfectly defined variables. This list is not exhaustive. CONCLUSION: The mitigation strategies to overcome these threats to validity require epidemiologic and statistical vigilance. Minimizing the highlighted types of bias in trauma research will facilitate clinical translation of more accurate and reproducible findings and improve the evidence-base that clinicians apply in their care of injured patients.

Early femur fracture fixation is associated with a reduction in pulmonary complications and hospital charges: a decade of experience with 1,376 diaphyseal femur fractures.

BACKGROUND: Early fixation (<24 hour) of femur fractures with an intramedullary nail (IMN) has been associated with a decreased incidence of pulmonary complication (PC) in stable trauma patients. Early fixation is in accordance with the "two-hit" hypothesis, that is, an increase in proinflammatory markers during Days 3 to 5 after injury, increases the risk of developing a PC. We hypothesized that early IMN fixation of femur fractures would be associated with a decreased incidence of PC, hospital stay, and overall charges. METHODS: A retrospective review of all trauma patients with diaphyseal femur fractures was performed from January 2000 through December 2010 at an academic Level 1 trauma center. The cohort was divided into those who underwent early fixation (<24 hours) and delayed fixation (≥24 hours). Multivariable logistic regression modeling was used to adjust for the anatomic (Injury Severity Score [ISS]) and physiologic (Revised Trauma Score [RTS]) severity of injury. The primary outcome of interest was PC, defined as the presence of pneumonia (PNA), pulmonary embolism, or adult respiratory distress syndrome. Continuous variables are expressed as mean (SD). The analysis was repeated for patients with an ISS of greater than 15 and an ISS of greater than 25. RESULTS: During the study period, 1,755 patients were admitted with a diaphyseal femur fracture, of whom 1,376 patients underwent primary IMN. A total of 1,032 (75%) underwent early fixation (median, 7.4 hours; interquartile range [IQR], 3.7-12.9 hours), and 344 (25%) underwent delayed fixation (median, 40.9 hours; IQR, 31.0-64.9 hours). The early fixation group had lower ISS (median [IQR], 10 [10-19] vs. 17.5 [10-27]; p < 0.001) and a higher RTS (median [IQR], 7.84 [7.84-7.84] vs. 7.84 [7.84-7.84]; p < 0.001). PC were reduced in the early fixation group, (3.9% vs. 13.4%, p < 0.001). Specifically, there was a decreased incidence of PNA (2% vs. 11%, p < 0.001), pulmonary embolism (2% vs. 4%, p < 0.21), and adult respiratory distress syndrome (0.002% vs. 0.02%, p < 0.001). After adjustment for anatomic (ISS) and physiologic (RTS) indices of injury severity, early fixation was independently associated with a reduction in PC (odds ratio, 0.43; 95% confidence interval, 0.25-0.72; p = 0.002). The early fixation group also had a decrease in hospital length of stay (median [IQR], 6 [4-11] vs. 10 [6-17]; p < 0.001), ventilator days (median [IQR], 0 [0-0] vs. 0 [0-4]; p < 0.001), and hospital charges (median [IQR], $59,561 [$38,618-$106,780] vs. $97,018 [48,249-205,570]; p < 0.001). Mortality was low in both groups (0.4% vs. 1.7%, p < 0.01). Similar results were seen in patients with an ISS of greater than 15 and ISS of greater than 25. CONCLUSION: Controlling for anatomic and physiologic severity of injury, early femoral IMN was associated with an almost 60% reduction in odds of developing PCs. Early fixation was also associated with a reduction ventilator days, hospital length of stay, and overall hospital charges. As the list of "never events" continues to expand and improving quality of care while reducing costs is emphasized, early (<24 hours) definitive operative intervention seems to decrease complications, achieve early hospital discharge, and reduce hospital charges. LEVEL OF EVIDENCE: Therapeutic study, level IV.

Mammography screening behaviors of women exposed prenatally to diethylstilbestrol.

BACKGROUND: In utero diethylstilbestrol (DES) exposure is a risk factor for rare development of vaginal and cervical cancer and may potentially be a risk factor for breast cancer. Mammography use in this population is relatively unknown; therefore, this study aims to determine if in utero DES exposure is associated with the frequency of mammography screening examinations while considering demographic and clinical factors. METHODS: Using combined DES cohort questionnaire data, self-reported mammography screening over the past 5 years (2001-2006) was analyzed in women aged ≥45 years. Binary logistic regression assessed if DES exposure was associated with mammography use after adjustment for benign breast disease (BBD), previous cancer diagnosis, and whether insurance access influenced screening use. RESULTS: Overall, the frequency of mammography examinations was similar for both DES-exposed and unexposed women. DES-exposed (n=2986) and unexposed women (n=1397) over the age of 44 reported receiving ≥3 mammography examinations in the past 5 years (73.8% and 74.0%, respectively). After adjustment, DES exposure was not associated with ≥3 mammograms in the past 5 years compared to ≤2 examinations (odds ratio [OR] 1.00, 95% confidence interval [CI] 0.86-1.17), p=0.99). CONCLUSIONS: In utero DES exposure was not associated with mammography use, nor was health insurance status or a BBD or cancer diagnosis. Because of the potential elevated risk for breast cancer in women exposed prenatally to DES, continued monitoring of standard mammography recommendations is recommended for this group, which is predominantly over the age of 45.

Breast cancer screening in women exposed in utero to diethylstilbestrol.

PURPOSE: To determine if women exposed in utero to diethylstilbestrol (DES) are more likely than unexposed women to receive recommended or additional breast cancer screening examinations. METHODS: 1994 Diethylstilbestrol-Adenosis (DESAD) cohort data are used to assess the degree of recommended compliance of breast cancer screenings found in 3140 DES-exposed and 826 unexposed women. Participants were enrolled at four sites: Houston, Boston, Rochester, and Los Angeles. Logistic regression modeling was used to analyze mailed questionnaire data that included reported frequency over the preceding 5 years (1990-1994) of breast-self examinations (BSEs), clinical breast examinations (CBEs), and mammograms. RESULTS: DES-exposed women exceeded annual recommendations for CBEs (aOR 2.20, 95% CI, 1.04-4.67) among women without a history of benign breast disease (BBD) compared with unexposed women. There were no other statistically significant differences between exposed and unexposed women who reported performing BSEs, CBEs (<40 years of age), and mammographies, regardless of BBD history. CONCLUSIONS: The majority of DES-exposed women receive breast cancer screenings at least at recommended intervals, but over two thirds do not perform monthly BSEs. Future efforts should be focused on further educating this and other at-risk populations through mailed reminders and during patient consultations on the benefits of screening examinations.

Cervical screening and general physical examination behaviors of women exposed in utero to diethylstilbestrol.

OBJECTIVE: To estimate whether women exposed in utero to diethylstilbestrol (DES) report receiving more cervical and general physical examinations compared to unexposed women. MATERIALS AND METHODS: 1994 Diethylstilbestrol Adenosis cohort data are used to assess the degree of recommended compliance of cervical screenings found in 3,140 DES-exposed and 826 unexposed women. Participants were enrolled at 4 sites: Houston, Boston, Rochester, and Los Angeles. Logistic regression modeling was used to analyze mailed questionnaire data, which included reported frequency over the preceding 5 years (1990-1994) of Papanicolaou smears and general physical examinations. RESULTS: Diethylstilbestrol-exposed women exceeded the recommended frequency of Papanicolaou smear screenings [adjusted odds ratio (aOR) = 2.15, 95% CI (confidence interval) = 1.60-2.88] compared to the unexposed. This association held among those without a history of cervical intraepithelial neoplasia (aOR = 1.88, 95% CI = 1.35-2.62). Diethylstilbestrol-exposed women exceeded annual recommendations for physical examinations (aOR = 2.27, 95% CI = 1.16-4.43) among women without a history of chronic disease when compared to unexposed women. CONCLUSIONS: Most DES-exposed women are receiving cervical cancer screening at least at recommended intervals, but one third of the women are not receiving annual Papanicolaou smear examinations.
