Meeting the imperative to improve physician well-being: assessment of an innovative program.

BACKGROUND: Improving physician health and performance is critical to successfully meet the challenges facing health systems that increasingly emphasize productivity. Assessing long-term efficacy and sustainability of programs aimed at enhancing physician and organizational well-being is imperative. OBJECTIVE: To determine whether data-guided interventions and a systematic improvement process to enhance physician work-life balance and organizational efficacy can improve physician and organizational well-being. DESIGN AND PARTICIPANTS: From 2000 to 2005, 22-32 physicians regularly completed 3 questionnaires coded for privacy. Results were anonymously reported to physicians and the organization. Data-guided interventions to enhance physician and organizational well-being were built on physician control over the work environment, order in the clinical setting, and clinical meaning. MEASUREMENTS: Questionnaires included an ACP/ASIM survey on physician satisfaction, the Maslach Burnout Inventory (MBI), and the Quality Work Competence (QWC) survey. RESULTS: Emotional and work-related exhaustion decreased significantly over the study period (MBI, p = 0.002; QWC, p = 0.035). QWC measures of organizational health significantly improved initially and remained acceptable and stable during the rest of the study. CONCLUSIONS: A data-guided program on physician well-being, using validated instruments and process improvement methods, enhanced physician and organizational well-being. Given the increases in physician burnout, organizations are encouraged to urgently create individual and systems approaches to lessen burnout risk.

A 30-year prospective follow-up study of hyperactive boys with conduct problems: adult criminality.

OBJECTIVE: To compare the official arrest records for a large number of hyperactive boys (N = 179), most with conduct problems, and 75 control boys; to examine childhood IQ, socioeconomic status, and parent reports of childhood hyperactivity and conduct problems for their contribution to criminal behavior in adulthood; and to compare adult outcome for multimodality-treated (MMT) and drug-treated-only (DTO) hyperactives. METHOD: We report on the official arrest history from early to mid- (18 to 38 years of age) adulthood in these 254 white subjects. RESULTS: Ninety one percent of subjects were followed up. California official arrest records were obtained on all of these subjects. Hyperactive subjects had significantly higher arrest, conviction, and incarceration rates compared with controls. Childhood antisocial behaviors, socioeconomic status, and IQ predicted adult criminality. Multimodality-treated boys with Hyperactive/ADHD (attention-deficit/hyperactivity disorder) did not fare better than DTO boys with ADHD. CONCLUSIONS: Hyperactive/ADHD boys with conduct problems are at increased risk for adult criminality. Hyperactive boys without childhood conduct problems are not at increased risk for later criminality. An intensive 3-year MMT treatment of 6- to 12-year-old hyperactive boys is insufficient to prevent later adult criminality.

Risk counseling and management in patients with lobular carcinoma in situ.

BACKGROUND: The understanding of lobular carcinoma in situ (LCIS) has evolved since it was first described. LCIS once was thought to be a premalignant condition, but now it is considered a marker for increased risk for developing invasive breast cancer. We evaluated patient perception of risk, counseling, and subsequent management. METHODS: A community cancer registry of 3,605 cases of breast cancer was reviewed. Fifty-five (1.5%) patients with LCIS as their sole diagnosis were identified and these patients were sent a questionnaire. RESULTS: Forty of 55 patients completed the questionnaire for a 73% response rate. The patients' perception of lifetime risk for invasive cancer was variable. Surgeons performed the majority of counseling. Fourteen patients (35%) were placed on a selective estrogen-receptor modulator. Eleven patients (28%) had bilateral mastectomy. Three patients had unilateral mastectomy. Screening recommendations included an annual mammography (64%), a professional examination (64%), and a monthly self-breast examination (75%). CONCLUSION: A patient's perception of risk for invasive breast cancer after a diagnosis of LCIS is widely variable. Patients will adhere to suggested screening recommendations. Surgeons are performing the majority of counseling and must stay abreast on current recommendations.

Geographic variation in sentinel node adaptation by practicing surgeons in Oregon.

BACKGROUND: The sentinel node biopsy (SNB) technique is an important tool in the diagnosis and treatment of breast cancer and melanoma. However, surgeons in Oregon have not universally adopted its use. METHODS: Mailed questionnaire. RESULTS: The response rate was 32%. Seventy-four (76%) of the surgical respondents perform routine SNB; 49% completed courses, and 32% learned the technique in residency. Sixty-one (89%) performed axillary dissection with their initial cases. It took 21 of 40 (52%) surgeons greater than a year to accrue 20 cases. Of 23 surgeons (24%) not performing SNB, 89% believed it was an important skill to obtain, and 70% thought they would benefit from proctoring opportunities. Six (26%) did not have technological support at their hospital. Surgeons at hospitals with less than 50 beds (P = .001) and at rural hospitals (P = .003) were less likely to perform SNB. CONCLUSION: The majority of urban general surgeons in Oregon use SNB in their practice. However, the incorporation of SNB for surgeons practicing in smaller hospitals and rural settings is less frequent than in the urban environment. As SNB becomes the standard of care, we need to overcome these barriers so that patients can have access to this procedure in their own communities.

Combination glutathione and anthocyanins as an alternative for skin care during external-beam radiation.

OBJECTIVE: Radiation dermatitis during therapy for breast malignancy can cause significant morbidity and delay treatment. RayGel (reduced glutathione and anthocyanins; Integrative Therapies, Portland, OR) appears to decrease this skin reaction, prompting us to undertake an objective evaluation of RayGel's effectiveness. METHODS: Patients undergoing whole breast external-beam irradiation were randomized to treatment with placebo or RayGel. Patients and investigators/staff were blinded to treatment assignment. Skin reaction was documented by photograph and severity scale. RESULTS: Thirty-two patients were enrolled. Thirty patients were randomized to receive placebo (n = 15) or RayGel (n = 15). Scores were calculated by percent of breast skin involved and grade of reaction. The group receiving RayGel had a lower average score, 93.7, versus the placebo group, 123.3. CONCLUSION: RayGel provides skin protection during radiation therapy, superior to that observed with standard skin care and placebo. This formula may reduce discomfort associated with breast irradiation and thereby allow more consistent completion of radiation courses for the treatment of breast cancer.

Perspective on reconstruction after mastectomy.

BACKGROUND: We sought to evaluate the factors influencing our patients to receive or forego reconstruction after mastectomy and their subsequent satisfaction with their decision. METHODS: A questionnaire was sent to 819 patients who underwent mastectomy from 1994 to 1998 in a community-based health system. RESULTS: Response rate was 50% (408 of 819). Overall, 92% (n = 243) of women who did not have reconstruction and 89% (n = 152) of women who did proceed with reconstruction were happy with their decision. Fifty-five (17%) respondents were not offered reconstruction. For this group, age was a significant factor as 64% of them were 60 years or older (P < 0.0001). Dissatisfied patients were disappointed with their cosmetic, sensory, or functional outcome. Their result did not meet their expectations. There were no significant differences noted on the basis of marital status. CONCLUSION: Ninety percent of patients adjust well to mastectomy whether or not they receive reconstruction if they make informed decisions with realistic expectations. Surgeons should offer reconstruction to women of all ages although patients over 60 years old are less likely to proceed with, and complete, reconstruction.

Estimating normal optic nerve axon numbers in non-human primate eyes.

PURPOSE: The goal of the present study is to develop a semi-automated method to estimate accurately, with minimum variance, the total number of axons by counting a subset of the axons within a primate optic nerve. METHODS: Using an imaging analysis system, axons in 50% of the area of cross-sections of the retrobulbar optic nerve from five adult Rhesus monkeys were counted and extrapolated as an estimate of total axon number of the optic nerves. Both neural and non-neural areas were sampled. With the coordinates of the counts topographically registered, axon numbers within areas ranging from 1 to 50% were resampled. A Monte Carlo and theoretical estimate of the standard deviation of the total axon count for each sampled area was computed. RESULTS: The mean cross-sectional area of the five optic nerves counted was 7.26 +/- 0.6 mm2, and the mean total axon count of the optic nerve area was 1,304,8168 +/- 89,112. When sampling less than 8% of the optic nerve, the standard deviation within the individual of the total estimated axon number increased sharply. CONCLUSION: With this technique, the variance within each individual increased only slightly when the counting area was reduced from 50 to 8%, but increased sharply when the counted area became less than 8%. While counting less than 8% of the optic nerve area gives a good estimation of total axon count, the effect of a substantial increase in the standard deviation on the statistical power needed to differentiate group differences will depend on the study design.

Benign paroxysmal positional nystagmus in hospitalized subjects receiving ototoxic medications.

OBJECTIVE: To investigate the occurrence of benign paroxysmal positional nystagmus in subjects undergoing treatment with potentially ototoxic medications. STUDY DESIGN: Prospective and retrospective record reviews. SETTING: Tertiary referral neurotology clinic; clinical research and technology center. SUBJECTS: Ninety-nine hospitalized subjects undergoing treatment of infectious disease or carcinoma with potentially ototoxic medications. INTERVENTIONS: Records review, tests of vestibular function. MAIN OUTCOME MEASURE: Results of Hallpike positional tests for benign paroxysmal positional nystagmus (electro-oculography). RESULTS: Forty-one (41%) of 99 subjects were female and 58 (59%) were male. Age range was 15 to 73 years (mean, 47 years). Forty-nine (50%) of 99 subjects had an unequivocally positive Hallpike test for benign paroxysmal positional nystagmus in one or both ears. The occurrence of benign paroxysmal positional nystagmus in the Hallpike-positive population was distributed equally across age decades. Of the 49 subjects with benign paroxysmal positional nystagmus, 22 (44%) were female and 27 (56%) were male. CONCLUSIONS: Benign paroxysmal positional nystagmus is the most common cause of vertigo in the general population, including subjects receiving ototoxic drugs. Complaints of vertigo in subjects receiving ototoxic drugs therefore may or may not indicate onset of ototoxicity. Occurrence of benign paroxysmal positional nystagmus in subjects receiving ototoxic drugs was independent of gender or age. The high occurrence rate of benign paroxysmal positional nystagmus in subjects receiving potentially ototoxic medications is consistent with the observation that benign paroxysmal positional nystagmus occurs in combination with many pathologic conditions. Benign paroxysmal positional nystagmus presenting in subjects receiving ototoxic drugs may complicate the clinical identification of ototoxicity and obfuscate clinical decision-making processes.

Effects of a geriatrician-led hip fracture program: improvements in clinical and economic outcomes.

The hip fracture service (HFS) is an interdisciplinary, geriatrician-led program instituted to improve the care of frail elderly people who present to the hospital with acute hip fracture. The HFS pilot project used existing hospital personnel and facilities and initiated new practices, including set protocols, preprinted orders, and standardized assessments, to achieve and evaluate patient triage and care and hospital cost savings. Outcome measures for 91 patients with acute hip fracture consecutively admitted to the HFS were compared with those of 72 historical controls managed under standard care in the prior year. Analysis demonstrated better outcomes in terms of length of stay (6.1+/-2.4 days for standard care, 4.6+/-1.1 days for the HFS; P<.001) and time to surgery (<24 hours after admission in 22.2% of standard care patients vs 50.5% of HFS patients; P<.001). Furthermore, the HFS model showed a reduction in total costs, resulting in a gain in net income, from a deficit of $908+/-4,977 (95% confidence interval (CI)=-$2,078-261) per patient in the standard group to a gain of $1,047+/-2,718 (95% CI=$481-1,613) per patient in the HFS group (P<.002). The findings suggest that care with set protocols overseen by a trained lead physician may improve the quality and cost effectiveness of managing elderly patients with hip fracture. Although the results must be interpreted with caution because of the pre-post design, this pilot study provides a model of care for further hypothesis generation and more rigorous testing into the quality and financial benefits of a geriatrics-led care process.

Tongue cancer: Is there a difference in survival compared with other subsites in the oral cavity?

PURPOSE: Advances in the management of patients with oral squamous cell carcinoma (OSCC) have confounded the importance of site in predicting overall prognosis. The purpose of this retrospective study was to review the outcome of patients with OSCC and to determine if site is a significant predictor of survival or disease-free survival. PATIENTS AND METHODS: The records of 233 patients that underwent surgery for resectable OSCC treated at a single institution from 1993 to 2003 were identified. Patients with positive surgical margins, high grade histology, aggressive biologic behavior, or advanced stage disease underwent adjuvant radiotherapy or chemoradiotherapy. The demographics, site, stage, pathologic, treatment, and survival data were collected and statistically analyzed in an attempt to identify predictors of loco-regional control and disease-free survival. Descriptive statistics were calculated for each variable and survival was calculated using the Kaplan-Meier method. For purposes of comparison, patients were divided into 2 groups: those with tongue lesions (n = 73) and all other sites (n = 152). The Cox proportional hazards model was used to distinguish different survival rates between the groups. RESULTS: Two hundred fifteen patients consisting of 104 males (48%) and 111 females (52%) met the criteria for inclusion in the study. Overall and disease-free survival rates were 56% and 58%, respectively. Stage and grade were identified as having a statistically significant effect on survival (P = .0014, likelihood ratio chi2 = 0.04, 1 degree of freedom; and P = .026, chi2 = 5, 1 degree of freedom, respectively). There was no significant difference in survival between patients with tongue cancer and other sites in the oral cavity (P = .8, chi2 = .04, 1 degree of freedom). CONCLUSIONS: Grade and stage are significant predictors of overall and disease-free survival for patients with OSCC. In this study, however, there was no survival difference between patients with tongue cancer and cancers located at other sites in the oral cavity.

Prognostic factors in intraoral squamous cell carcinoma: the influence of histologic grade.

PURPOSE: The purpose of this retrospective study was to review the outcome of patients with oral cavity squamous cell carcinoma treated at a single institution by primary surgical resection with or without adjuvant radiotherapy or chemoradiotherapy and to identify factors affecting survival and locoregional control. PATIENTS AND METHODS: The records of 233 patients with oral cavity squamous cell carcinoma treated at a single institution from 1993 to 2003 were identified from the Legacy Emanuel Hospital and Health Center's cancer registry (Portland, OR). All patients undergoing surgical resection as a primary treatment modality were included in the study. Patients with nonresectable disease, distant metastasis, and those with inadequate follow-up data were excluded from the study. Patients with positive surgical margins, high-grade histology, aggressive biologic behavior, or advanced staged disease underwent adjuvant radiotherapy or chemoradiotherapy. The data collected included age, gender, race, tumor site, margin status, grade, TNM stage, cancer therapies, and cancer status. Data were statistically analyzed in an attempt to identify predictors of locoregional control and disease-free survival. Descriptive statistics were calculated for each variable and survival was calculated using the Kaplan-Meier method. Prognostic factors were analyzed using the Cox proportional hazard model. RESULTS: Two hundred fifteen patients consisting of 119 men (55%) and 123 females (52%), with an average age at diagnosis of 66 years (SD +/- 14), met the criteria for inclusion in the study. Average tumor size was 23.5 mm (SD +/- 14.1). Overall 5-year survival was 56% and disease-free survival at 5 years was 58%. Stage and grade were identified as having a statistically significant effect on survival (P = .014; likelihood ratio chi-square = 10.7, 3 degrees of freedom; and P = .026; likelihood ratio chi-square = 5, 1 degree of freedom, respectively). Neither age, gender, race, tumor site, nor positive margins showed a statistically significant effect on survival (P > .05). CONCLUSION: This study highlights the importance of grade and stage as independent factors in predicting survival in patients with oral squamous cell carcinoma.

Management and outcome of patients with malignant salivary gland tumors.

PURPOSE: Refined imaging technology, the use of external beam radiation, neutron beam therapy, and chemotherapy, has altered management strategies for patients with salivary gland malignancies during the past 2 decades. Although treatment remains primarily surgical, optimal therapeutic regimens have yet to be fully realized. The purpose of this investigation is to report our experience with the management of patients with a variety of malignant salivary gland neoplasms that were treated with various combinations of surgery, radiation, and chemotherapy and to review treatment outcome in an effort to identify predictors of survival and locoregional control. MATERIALS AND METHODS: The records of all patients with malignant salivary gland tumors presenting for treatment at our institution between 1992 and 2002 were retrospectively reviewed. Variables were collected and outcome measures were defined in terms of overall survival, disease-free survival, and locoregional control. Descriptive statistics were compiled and statistically evaluated. Survival was described using the Kaplan-Meier method. Prognostic factors were assessed using the Cox proportional hazards model. Clinical and reconstructive factors were reviewed. RESULTS: Eighty-five patients (35 males and 50 females) ranging in age from 16 to 89 years (mean, 58.6 years) met the criteria for inclusion in the study. The majority of tumors were located in the parotid gland (n = 42), with a significant minority located in the minor salivary glands (n = 29), followed by the submandibular gland (n = 8) and the sublingual gland (n = 6). Mucoepidermoid carcinoma was the most common neoplasm (n = 40). More than half of the patients presented in early-stage disease (stage I = 36, stage II = 17, stage III = 8, stage IV = 25). All patients were treated with surgery as the primary modality. Neck dissection was performed in 29% of patients, and more than half (56%) were treated with adjuvant external beam radiation therapy to a dose of 50 to 70 Gy. Patients were, in general, immediately reconstructed at the time of ablation using composite free tissue transfer when appropriate, local/regional rotational flaps, or maxillary obturators. The disease-free survival rate and locoregional control rate at 5 years were 77% and 86%, respectively. Stage (P = .0017), grade (P = .00044), cervical lymph node metastasis (P = .03), and age (P = .01) proved to make a statistically significant contribution when describing outcome. Neither site (P = .5), the presence of positive margins (P = .3), nor perineural invasion (P = .7) had a significant impact on survival. CONCLUSIONS: The treatment of salivary gland malignancies remains primarily surgical, although adjunctive radiotherapy may play an important role in those patients with advanced-stage disease. This study confirms the contributions of stage, grade, age, and cervical metastasis for describing survival. The benefits of combined modality therapy awaits prospective clinical trials.

Is detection of oral and oropharyngeal squamous cancer by a dental health care provider associated with a lower stage at diagnosis?

PURPOSE: Stage at diagnosis is the most important prognostic indictor for oral and oropharyngeal squamous cell cancers (SCCs). Unfortunately, approximately 50% of these cancers are identified late (stage III or IV). We set out to examinationine the detection patterns of oral and oropharyngeal SCCs and to determine whether detection of these cancers by various health care providers was associated with a lower stage. PATIENTS AND METHODS: Data were gathered on 51 patients with newly diagnosed oral or oropharyngeal SCC through patient interview and chart audit. In addition to demographic data, specific inquiry was made regarding the circumstances surrounding the identification of the lesion. The main outcome measure was tumor stage grouping based on detection source. RESULTS: Health care providers detecting oral and oropharyngeal SCCs during non-symptom-driven (screening) examinations were dentists, hygienists, oral and maxillofacial surgeons, and, in 1 case, a denturist. All lesions detected by physicians occurred during a symptom-driven examination. Lesions detected during a non-symptom-driven examination were of a statistically significant lower average clinical and pathologic stage (1.7 and 1.6, respectively) than lesions detected during a symptom-directed examination (2.6 and 2.5, respectively). Additionally, a dental office is the most likely source of detection of a lesion during a screening examination (Fisher exact test, P =.0006). Overall, patients referred from a dental office were of significantly lower stage than those referred from a medical office. Finally, patients who initially saw a regional specialist (dentist, oral and maxillofacial surgeon, or otolaryngologist) with symptoms related to their lesion were more likely to have appropriate treatment initiated than those who initially sought care from their primary care provider. CONCLUSION: Overall, detection of oral and oropharyngeal SCCs during a non-symptom-driven examination is associated with a lower stage at diagnosis, and this is most likely to occur in a dental office. A regional specialist was more likely than a primary care provider to detect an oral or oropharyngeal SCC and initiate the appropriate treatment during the first visit for symptoms related to the lesion.

Facial computed tomography use in trauma patients who require a head computed tomogram.

PURPOSE: Head-injured patients admitted to a trauma center may or may not have associated facial fractures. Most head-injured patients undergo head computed tomography (CT) scan early in their evaluation. The question of adding a facial CT at the time of the head CT can be unclear. The aims of our study are 1) to analyze how the facial CT is used in conjunction with the head CT in facial fracture trauma patients, 2) to recognize unique identifiers that would aid the surgeon's decision-making process to order a facial CT in continuity with a head CT, and 3) to examine what is characteristic of head trauma patients who receive a facial CT separately, at some point after the head CT. Materials and methods Data were retrospectively reviewed for a 5-year period at a level I trauma center in which all patients who present with craniomaxillofacial trauma are managed by the oral and maxillofacial surgery (OMFS) service. Included patients must have obtained a head CT during initial resuscitation and be diagnosed with a facial fracture during the same hospital stay. These patients were divided into 3 groups: those who had a 1) head CT only, 2) head CT and facial CT at the same time, and 3) head CT with the facial CT performed at a later time. RESULTS: A total of 9,871 patients were admitted to the trauma service during a 5-year period and 4,926 patients (49.9%) had head CT performed. Of this group, 12% had facial fractures, and the most common associated injury in this group was facial lacerations and concussions. The nasal fracture followed by the orbital fracture was the most common fracture type. Eighty-four percent of the time, the facial CT was used to help diagnose facial fractures in this patient population. The 3 different groups showed unique trends. CONCLUSION: Six points were identified in our study that can augment the physical examination in patients who require head CT. The following points can help prompt the clinician to order a combination head and facial CT: 1) 12% of trauma patients who require a head CT will have a facial fracture, whereas half of these patients will have multiple facial fractures. 2) Orbital fractures are commonly missed in this group and often require a secondary scan such as coronal views for accurate diagnosis. 3) Facial lacerations correlate with ordering a combination head and facial CT. 4) The most common facial fracture identified among patients receiving a trauma head CT is the nasal fracture. 5) The use of the facial CT in more severely injured patients tended to be delayed and was related to increased hospital and intensive care unit days. 6) Only 16% of facial fracture patients who had received an initial trauma head CT did not require further facial CT scanning.

Tobacco smoking history and presentation of oral squamous cell carcinoma.

PURPOSE: The association between tobacco smoking and oral squamous cell carcinoma is well established. However, few studies have evaluated the smoking history based on a smoking versus never-smoking history or analyzed the relationship between smoking history and site and stage of presentation. The purpose of this study was to examine the relationship between smoking versus never-smoking history and the stage and site of presentation of oral squamous cell carcinoma. PATIENTS AND METHODS: The design of this study was a retrospective review of all patients presented at the Legacy Emanuel Hospital Head and Neck Tumor Board in Portland, Oregon, with a biopsy-proven oral squamous cell carcinoma between 1998 and 2000. Data collected included age, gender, smoking history (smoker versus never smoker), pack-years of tobacco, site, and stage (T, N, and group stage) at presentation. RESULTS: A total of 67 patients were reviewed; 33% of patients were never smokers and 67% of patients had a history of smoking with an average of 49.4 pack-years. The floor of mouth and gingiva were the most commonly affected sites. There was a statistically significant difference between site of presentation and a history of smoking (P =.0007). The 2 sites that showed a significant association with smoking were posterolateral tongue and floor of mouth. CONCLUSIONS: The findings of this study demonstrate that approximately one third of patients with oral squamous cell carcinoma will report that they have never smoked. There was a strong association between a history of smoking and carcinoma involving the posterolateral tongue and floor of mouth.

Management of cerebrospinal fluid leak associated with craniomaxillofacial trauma.

PURPOSE: The management of persistent, post-traumatic cerebrospinal fluid (CSF) rhinorrhea and otorrhea remains a surgical challenge. Repair of CSF leaks has evolved from that of an intracranial approach to one that is primarily extracranial and endoscopic. The purpose of this retrospective analysis is to determine the incidence of persistent CSF rhinorrhea and otorrhea and assess the clinical outcomes of patients presenting to a level 1 trauma center with posttraumatic CSF leaks who were managed by both surgical and nonsurgical means. PATIENTS AND METHODS: The records of all patients with basilar skull fractures and/or severe facial trauma presenting to a major level 1 trauma center from 1991 to 2001 were reviewed. Patients diagnosed with CSF otorrhea or rhinorrhea, who had not undergone an intracranial procedure, elevation of depressed skull fractures, or received a ventriculostomy, were identified and their demographics recorded. For purposes of statistical comparison, patients were divided into 2 groups: "leak" and "no leak." All patients in the leak group were initially observed for a period of 7 to 10 days. Persistent CSF leaks were managed by CSF diversion via lumber drainage for 5 to 7 days. Extracranial repair was performed only if lumbar drainage failed to resolve the leak. RESULTS: Seven hundred thirty-five patients were identified who met the criteria for inclusion in the study. Thirty-four patients (incidence, 4.6%) were identified with CSF leak presenting as otorrhea (n = 25 [75.8%]) or rhinorrhea (n = 9 [26.5%]), which was diagnosed by clinical, laboratory, or radiographic examination (average age, 28.2 years; age range, 2 to 80 years; 23 males and 11 females). All patients in this study experienced successful resolution of CSF otorrhea or rhinorrhea by using a variable combination of observation, CSF diversion, and extracranial repair. There were no complications or cases of meningitis. Twenty-eight patients (84.6%) experienced uncomplicated resolution of the leak without treatment in 2 to 10 days. Persistent CSF leak, defined by drainage greater than 7 days after injury, was identified in 6 patients (incidence, 0.8%), all except 1 who underwent CSF diversion via a lumbar drain for a period of 5 to 10 days. Two of these patients were treated successfully; the remaining 4 patients required surgical procedures. CONCLUSIONS: Post-traumatic CSF leaks are uncommon and will usually resolve without surgical intervention. Successful management in refractory cases often involves a combination of observation, CSF diversion, and/or extracranial and intracranial procedures.

Patterns of maxillofacial injuries related to interaction with horses.

PURPOSE: Studies of trauma patients have described patterns of injuries sustained from unfortunate encounters with large animals. However, the patterns of maxillofacial injuries have yet to be reported. The goal of this investigation was to describe and report on maxillofacial injuries that are associated with interaction with horses. PATIENTS AND METHODS: Charts were selected from the trauma registry by E-code at a level 1 trauma center in Portland, OR. A retrospective review was performed on charts collected from the previous 5 years (1998-2002). Data were collected according to patient, pattern of injuries, and mechanism of injury. RESULTS: The 62 patients who were identified consisted of 15 males (24%) and 47 females (76%) and ranged in age from 1 to 83 years (average age, 32 years; most frequent age, 12 years). Most of the accidents occurred in the spring months and involved a horse known to the patient. The most common mechanism was falling from the horse. However, being kicked was correlated with a more serious injury (P =.048). The most frequent injury was abrasion/contusion (24 [39%]), second were lacerations (20 [32%]), and third were fractures (18 [29%]). Fifty (81%) were not wearing helmets. Forty-six (74%) of the patients had other associated injuries. CONCLUSIONS: In patients with facial injuries related to horses, younger females were the most frequently involved. Facial injuries were often associated with other types of injuries. Nearly a third of the facial injuries sustained were fractures. The percentage of riders without a helmet was high. However, in our patient population, wearing a helmet does not seem to add any protection to the face, and almost all of the accidents involved a horse known to the patient. More education aimed at horse owners regarding the use of helmets, proper handling and riding skills, and supervising young riders is encouraged to prevent further injuries.

Survey of trauma patients requiring maxillofacial intervention, ages 56 to 91 years, with length of stay analysis.

PURPOSE: The purpose of this study was to analyze trauma patients, ages 55 and older, sustaining multiple injuries including maxillofacial trauma. Factors influencing length of intensive care unit stay (ICUS) and length of total hospital stay were delineated and examined to determine if specific causes of increased length of stay could be elucidated, and, once known, if these causes could translate into recommendations tailored to the oral and maxillofacial surgery trauma practice. PATIENTS AND METHODS: One hundred ninety-six patients, 55 years of age or older, who received either consultation alone, or consultation with surgical treatment, by oral and maxillofacial surgeons, from January 1991 to August 1998 were included in this study. Variables of interest included location of traumatic event, mechanism of injury, patient age and gender, comorbidities on presentation, Injury Severity Score (ISS), specific injuries incurred, ICUS, length of hospital stay (LOS), surgical interventions, and disposition. RESULTS: Complications were the statistically significant factor determining length of ICU stay. ICUS, complications incurred, and ISS were the important predictors of total LOS. The significant complications affecting LOS were infectious, respiratory, and hematologic complications. CONCLUSION: The number of complications the patient incurs after an injury can predict length of ICUS. Length of ICUS, ISS, and number of complications incurred were the strongest predictors for total length of hospital stay. Other variables, including age, gender, living or dead, blunt versus penetrating injury, ISS, fracture site (skull, midface, or lower face), and comorbidities on presentation were not statistically significant in this patient population. Infectious, respiratory, and hematologic complications were the complications most closely correlated with increasing length of ICUS and total hospital stay.
