Causes and effects of surgical delay in patients with hip fracture: a cohort study.

Abstract: Background The clinical effect of surgical delay in older patients with hip fracture is controversial. Discrepancies among study findings may be due to confounding that is caused by the reason for the delay or a differential effect on patient risk subgroups. Objective To assess the effect of surgical delay on hospital outcomes according to the cause of delay. Design Prospective cohort study. Setting A hip fracture unit in a university hospital in Spain. Patients 2250 consecutive elderly patients with hip fracture. Measurements Time to surgery, reasons for surgical delay, adjusted in-hospital death, and risk for complications. Results Median time to surgery was 72 hours. Lack of operating room availability (60.7%) and acute medical problems (33.1%) were the main reasons for delays longer than 48 hours. Overall, rates of hospital death and complications were 4.35% and 45.9%, respectively, but were 13.7% and 74.2% in clinically unstable patients. Longer delays were associated with higher mortality rates and rates of medical complications. After adjustment for age, dementia, chronic comorbid conditions, and functionality, this association did not persist for delays of 120 hours or less but did persist for delays longer than 120 hours (P = 0.002 for overall time effect on death and 0.002 for complications). The risks were attenuated after adjustment for the presence of acute medical conditions as the cause of the delay (P = 0.06 for time effect on mortality and 0.31 on medical complications). Risk for urinary tract infection remained elevated (odds ratio, 1.54 [95% CI, 0.99 to 2.44]). No interaction between delay and age, dementia, or functional status was found. Limitation This was a single-center study without postdischarge follow-up. Conclusion The reported association between late surgery and higher morbidity and mortality in patients with hip fracture is mostly explained by medical reasons for surgical delay, although some association between very delayed surgery and worse outcomes persists. Primary funding source None.

Efficacy of Different Treatment Alternatives for Obesity Hypoventilation Syndrome. Pickwick Study.

Abstract: Rationale: The incidence of obesity hypoventilation syndrome (OHS) may be increasing in parallel with the present obesity epidemic. Despite extensive noninvasive ventilation (NIV) and continuous positive airway pressure (CPAP) use in patients with OHS, information regarding efficacy is limited.Objectives: We performed a large, multicenter randomized controlled study to determine the comparative efficacy of NIV, CPAP, and lifestyle modification (control group) using daytime PaCO2 as the main outcome measure.Methods: Sequentially screened patients with OHS with severe sleep apnea were randomized into the above-mentioned groups for a 2-month follow up. Arterial blood gas parameters, clinical symptoms, health-related quality-of-life assessments, polysomnography, spirometry, 6-minute-walk distance, dropouts, compliance, and side effects were evaluated. Statistical analysis was performed using intention-to-treat analysis, although adjustments for CPAP and NIV compliance were also analyzed.Measurements and Main ...
