Objective Endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) allows preoperative tissue confirmation of malignancy, but fear of tumour cell dissemination along the needle track has limited its use. We hypothesised that if tumour cell dissemination occurs with EUS-FNA, survival after complete resection would be impaired. We aimed to evaluate the association of preoperative EUS-FNA with long-term outcomes of patients with resected pancreatic cancer. Design Using the linked Surveillance, Epidemiology, and End Results (SEER)–Medicare data, we identified patients with locoregional pancreatic cancer who underwent curative intent surgery from 1998 to 2009. The patients who received EUS-FNA within the peridiagnostic period were included in the EUS-FNA group. Patients who did not receive EUS evaluation or who underwent EUS without FNA were included in the non-EUS-FNA group. Overall survival and pancreatic cancer-specific survival were compared after controlling for relevant covariates. Results A total of 2034 patients with pancreatic cancer were included (90% pancreatic adenocarcinoma). Of these, 498 (24%) patients were in EUS-FNA group. Patients with multiple comorbidities and more recent diagnosis were more likely to receive EUS-FNA. In multivariate analysis, after controlling for age, race, gender, tumour histology, tumour stage, tumour grade, tumour location, SEER site, year of diagnosis, undergoing percutaneous aspiration/biopsy, Charlson Comorbidity Index, radiation and chemotherapy, EUS-FNA was marginally associated with improved overall survival (HR 0.84, 95% CI 0.72 to 0.99), but did not affect cancer-specific survival (HR 0.87, 95% CI 0.74 to 1.03). Conclusions Preoperative EUS-FNA was not associated with increased risk of mortality. These data suggest that EUS-FNA can be safely performed for the work-up of suspicious pancreatic lesions.

Objectives: To examine multiple chronic conditions and related health care expenditures in children. Methods: Retrospective cohort study of all dependents of Mayo Clinic employees aged 0-17 on Jan 1, 2004 with continuous health benefits coverage for 4 years (N=14,727). Chronic conditions, health care utilization, and associated expenditures were obtained from medical and pharmacy claims. Results: The most prevalent chronic conditions were asthma/chronic obstructive pulmonary disease (12%), allergic rhinitis (11%), and behavior problems (9%). The most costly conditions were congenital anomalies, asthma/chronic obstructive pulmonary disease, and behavior problems ($9602, $4335, and $5378 annual cost per child, respectively). Annual health care expenditures increased substantially with the number of chronic conditions, and a small proportion of children with multiple chronic conditions accounted for a large proportion of health care costs. In addition, those with multiple chronic conditions were more likely to persist in the top 10th percentile spender group in year-to-year spending. Conclusion: Children with multiple chronic conditions accounted for a large proportion of health care expenditures. These children were also likely to persist as high spenders in the 4-year time frame. Further research into effective ways to manage the health care delivery for children with multiple chronic conditions is needed.

Background— Decision aids (DAs) increase patient knowledge, reduce decisional conflict, and promote shared decision making (SDM). The extent to which they do so across diverse sociodemographic patient groups is unknown. Methods and Results— We conducted a patient-level meta-analysis of 7 randomized trials of DA versus usual care comprising 771 encounters between patients and clinicians discussing treatment options for chest pain, myocardial infarction, diabetes mellitus, and osteoporosis. Using a random effects model, we examined the impact of sociodemographic patient characteristics (age, sex, education, income, and insurance status) on the outcomes of knowledge transfer, decisional conflict, and patient involvement in SDM. Because of small numbers of people of color in the study population, we were not powered to investigate the role of race. Most patients were aged ≥65 years (61%), white (94%), and women (59%); two thirds had greater than a high school education. Compared with usual care, DA patients gained knowledge, were more likely to know their risk, and had less decisional conflict along with greater involvement in SDM. These gains were largely consistent across sociodemographic patient groups, with DAs demonstrating similar efficacy when used with vulnerable patients such as the elderly and those with less income and less formal education. Differences in efficacy were found only in knowledge of risk in 1 subgroup, with greater efficacy among those with higher education (35% versus 18%; P =0.02). Conclusions— In this patient-level meta-analysis of 7 randomized trials, DAs were efficacious across diverse sociodemographic groups as measured by knowledge transfer, decisional conflict, and patient involvement in SDM. To the extent that DAs increase patient knowledge and participation in SDM, they have potential to impact health disparities related to these factors.
