PROBLEM: Question: Are perioperative complications after hemiarthroplasty and total shoulder arthroplasty equivalent?
Answer: Multivariate analysis of patients undergoing TSA or HA in the NSQIP database suggests that patient factors-not the procedure being performed-are significant predictors of major complications. Controlling for patient comorbidities, we found no increased risk of perioperative major complications in patients undergoing TSA compared with HA.

SOLUTION: yes

PROBLEM: Question: Are chronic obstructive pulmonary disease patients with psychiatric disorders at greater risk of exacerbations?
Answer: Patients with psychiatric disorders are at greater risk of exacerbations treated in an outpatient setting but not those treated in an inpatient setting. These outpatient-managed exacerbations account for a significant proportion of the healthcare burden for COPD, so interventions should target patients with psychiatric disorders to improve management of COPD.

SOLUTION: yes

PROBLEM: Question: Does right ventricular lead positioning influence the benefits of cardiac resynchronization therapy in patients with heart failure and atrial fibrillation?
Answer: In this randomized controlled study, the exact RV pacing site, either apex or outflow tract, did not influence the benefits of CRT in a group of patients with chronic heart failure and AF. ClinicalTrials.gov ID: NCT00457834.

SOLUTION:
no
