RESUMO
BACKGROUND: Scaphoid fractures treated non-operatively and operatively may be complicated by nonunion. QUESTIONS/PURPOSES: We sought to test the primary hypothesis that the incidence density of scaphoid fracture treatment is higher than previously estimated, to determine the frequency and risk factors for nonunion treatment, and to determine whether the frequency of surgical treatment increased over time. METHODS: The MarketScan® database was queried for all records of treatment (casting and surgery) for closed scaphoid fractures over a 6-year period. We examined subsequent claims to determine frequency of additional procedures for nonunion treatment (revision fixation or vascularized grafting occurring 28 days or more after initial treatment). Trend analyses were used to determine whether changes in frequency of surgical treatment or revision procedure occurred. RESULTS: The estimated incidence density of scaphoid fracture is 10.6 per 100,000 person-years in a commercially insured population of less than 65 years of age. Of 8923 closed scaphoid fractures, 29 and 71% were treated with surgery and casting, respectively. The frequency of surgical treatment rose significantly, from 22.1% in 2006 to 34.1% in 2012. The frequency of nonunion treatment was 10.8% after surgery and 3% after casting; neither changed over time. Younger age, male sex, and surgical treatment are associated with a higher risk of nonunion treatment. CONCLUSIONS: Our estimated incidence of scaphoid fracture is higher than previously reported. The increased enthusiasm in the USA to surgically treat scaphoid fractures is reflected by our trend analysis. The frequency of surgical treatment for presumed nonunion after initial surgical management for closed scaphoid fractures exceeded 10%. Given the increased utilization of surgery, surgeons and patients should be aware of the frequency of nonunion treatment to inform treatment decisions.
RESUMO
BACKGROUND: Clostridium difficile infection (CDI) is a frequent cause of diarrhea among allogeneic hematopoietic cell transplant (HCT) recipients. It is unknown whether risk factors for CDI vary by time posttransplant. METHODS: We performed a 3-year prospective cohort study of CDI in allogeneic HCT recipients. Participants were enrolled during their transplant hospitalizations. Clinical assessments were performed weekly during hospitalizations and for 12 weeks posttransplant, and monthly for 30 months thereafter. Data were collected through patient interviews and chart review, and included CDI diagnosis, demographics, transplant characteristics, medications, infections, and outcomes. CDI cases were included if they occurred within 1 year of HCT and were stratified by time from transplant. Multivariable logistic regression was used to determine risk factors for CDI. RESULTS: One hundred eighty-seven allogeneic HCT recipients were enrolled, including 63 (34%) patients who developed CDI. 38 (60%) CDI cases occurred during the preengraftment period (days 0-30 post-HCT) and 25 (40%) postengraftment (day >30). Lack of any preexisting comorbid disease was significantly associated with lower risk of CDI preengraftment (odds ratio [OR], 0.3; 95% confidence interval [CI], 0.1-0.9). Relapsed underlying disease (OR, 6.7; 95% CI, 1.3-33.1), receipt of any high-risk antimicrobials (OR, 11.8; 95% CI, 2.9-47.8), and graft-versus-host disease (OR, 7.8; 95% CI, 2.0-30.2) were significant independent risk factors for CDI postengraftment. CONCLUSIONS: A large portion of CDI cases occurred during the postengraftment period in allogeneic HCT recipients, suggesting that surveillance for CDI should continue beyond the transplant hospitalization and preengraftment period. Patients with continued high underlying severity of illness were at increased risk of CDI postengraftment.
RESUMO
Background: Compressive neuropathy of the ulnar nerve at the elbow, or cubital tunnel syndrome (CuTS), is the second most common entrapment neuropathy of the upper extremity after carpal tunnel syndrome. While several studies have reported risk factors and outcomes for select populations (mostly surgical), it is difficult to interpret these data without an accurate measure of CuTS disease burden in the general population. Objective: To estimate the incidence of CuTS among US health plan enrollees, using a large administrative health care claims database comprised of individuals from all 50 states. Methods: An administrative database of commercial insurance beneficiaries was queried for diagnosis and treatment of CuTS over a 6-yr period. We examined subsequent claims to determine frequency of subsequent surgical treatment. Descriptive statistics were used to determine the association of incident cases and surgical treatment with age and gender. Results: The estimated adjusted incidence rate of CuTS is 30.0 per 100 000 person-years. Of the 53 401 identified new cases within this cohort from 2006 to 2012, 41.3% were treated surgically. Incident cases were identified more frequently in men than in women (31.2 vs 28.8 cases per 100 000 person-years), though we observed more cases in women than in men below 50 yr of age (20.9 vs 19.5 cases per 100 000 person-years). Overall, incident cases increase with age in both men and women. In addition to incident cases being more common with increasing age, the percentage of cases treated surgically also increases with age (surgery in 34.4% of cases in the 18-30 yr group vs 48.8% of cases in the 60-65 yr group). Conclusion: The purpose of this study was to estimate the incidence of CuTS among US health plan enrollees. This is the largest published study on the incidence of CuTS, and the first to look at a US population. The overall adjusted incidence of CuTS was 30.0 per 100 000 person-years. Of patients who developed CuTS, 41.3% were treated surgically during the study period. Our results corroborate previously reported literature suggesting incidence increases significantly with age, with a slightly higher incidence in males. A high percentage of people who were diagnosed with CuTS and ended up receiving surgical intervention (41.3%) were older males. These results may aid practitioners in providing some basic prognostic information to patients who develop CuTS.

BACKGROUND: We sought to determine the incidence of postmastectomy bleeding, identify bleeding predictors, and evaluate the economic impact. METHODS: Using the 2011 Healthcare Cost and Utilization Project-Nationwide Inpatient Sample, hospital discharges for a primary diagnosis of breast cancer were extracted using International Classification of Diseases, Ninth Revision, Clinical Modification procedure codes 85.34-85.48 for mastectomy and diagnosis codes 174.0-174.9 for breast cancer. Discharges with postoperative bleeding were identified using International Classification of Diseases, Ninth Revision, Clinical Modification diagnosis codes 998.11 and 998.12. Discharges with male gender or a history of coagulation disorders were excluded. Bleeding complication rates and reoperation rates were assessed. Predictors and the impact of bleeding on length of stay and hospital costs were determined using regression analysis and projected to the national level. RESULTS: A total of 7907 discharges met inclusion criteria; 201 had bleeding complications (2.54%), with 42 cases requiring reoperation. On univariate analysis, the presence of congestive heart failure (CHF), obesity, diabetes, chronic pulmonary disease, and the absence of concomitant reconstruction were associated with increased bleeding events. On multivariate analysis, only the presence of CHF remained as a significant predictor of bleeding complications (odds ratio [95% confidence interval], 2.45, [1.25-4.92], P = 0.009). On average, bleeding complications extended the length of stay by 1.3 d (P < 0.0001) while increasing hospital costs by $5495 per admission (P < 0.0001). Projected to a national level, bleeding complications accounted for an additional 1254 d of hospital care at a cost exceeding $5.3 million. CONCLUSIONS: Postmastectomy bleeding complications had an incidence of 2.54%, with CHF the only independent predictor identified. Such bleeding events, although infrequent, are associated with substantial economic costs.

BACKGROUND: Physicians are encouraged to disclose medical errors to patients, which often requires close collaboration between physicians and risk managers. METHODS: An anonymous national survey of 2,988 healthcare facility-based risk managers was conducted between November 2004 and March 2005, and results were compared with those of a previous survey (conducted between July 2003 and March 2004) of 1,311 medical physicians in Washington and Missouri. Both surveys included an error-disclosure scenario for an obvious and a less obvious error with scripted response options. RESULTS: More risk managers than physicians were aware that an error-reporting system was present at their hospital (81% versus 39%, p < .001) and believed that mechanisms to inform physicians about errors in their hospital were adequate (51% versus 17%, p < .001). More risk managers than physicians strongly agreed that serious errors should be disclosed to patients (70% versus 49%, p < .001). Across both error scenario, risk managers were more likely than physicians to definitely recommend that the error be disclosed (76% versus 50%, p < .001) and to provide full details about how the error would be prevented in the future (62% versus 51%, p < .001). However, physicians were more likely than risk managers to provide a full apology recognizing the harm caused by the error (39% versus 21%, p < .001). CONCLUSIONS: Risk managers have more favorable attitudes about disclosing errors to patients compared with physicians but are less supportive of providing a full apology. These differences may create conflicts between risk managers and physicians regarding disclosure. Health care institutions should promote greater collaboration between these two key participants in disclosure conversations.

BACKGROUND: To increase error reporting, a better understanding of physicians' and nurses' perspectives regarding medical error reporting in hospitals, barriers to reporting, and possible ways to increase reporting is necessary. METHODS: Nine focus groups--four with 49 staff nurses, two with 10 nurse managers, and three with 30 physicians--from 20 academic and community hospitals were conducted in May-June 2002 in the St. Louis metropolitan area. Qualitative analysis of focus group transcripts characterized participants' perspectives. RESULTS: Although participants knew they should report errors associated with serious adverse events, there was much uncertainty about reporting less serious errors or near misses. Nurses were more knowledgeable than physicians about how to report errors. All groups mentioned barriers to reporting, such as fear of reprisals and lack of confidentiality, time, and feedback after an error is reported. Some physicians doubted the benefit of reporting errors, but, generally, both physicians and nurses agreed that reporting was intended to change practice and policy to promote patient safety. CONCLUSIONS: A culture characterized by anonymous reporting, freedom from repercussions, and feedback about error reports should promote error reporting.

OBJECTIVE: To estimate whether maternal weight changes between pregnancies influence the risk for small for gestational age (SGA) births. METHODS: SGA cases (n = 8,062) below the tenth percentile birth weight for gestational age were selected from liveborn singletons born of Missouri residents during 1989-1997. Normal weight controls (n = 8,062) were selected according to birth year. The risk of SGA from interpregnancy body mass index (BMI) change and other maternal factors was estimated using logistic regression analysis. RESULTS: An increase in BMI between pregnancies decreased SGA risk (adjusted odds ratio = 0.8; 95% confidence interval 0.7, 1.0). Other risk factors were prior SGA (4.4; 4.0, 4.8), preeclampsia/eclampsia (2.6; 2.1, 3.2), maternal cardiac disease (1.8; 1.1, 2.9), inadequate weight gain (1.9; 1.8, 2.2), and cigarette smoking (1.9; 1.7, 2.3 for 1-9 cigarettes per day; 2.5; 2.2, 2.8 for 10-19/d; and 2.8; 2.5, 3.3 for 20/d or more). CONCLUSION: Increase in interpregnancy BMI lowers SGA risk, but adequate weight gain during pregnancy is more effective.
