Review Meta Analysis
Risk prediction models for postoperative delirium: a systematic review and meta-analysis.
Postoperative delirium (POD) is a common neuropsychiatric disorder characterized by inattention, fluctuating levels of consciousness, and disorganized thinking. POD can have serious consequences, including institutionalization and death. Risk stratification may target prevention to individuals at greater risk of POD. ⋯ Size of the models was not associated with their discriminatory performance. Instead of creating steadily new RPMs, existing RPMs should be further tested, improved, and meta-analytically integrated. It may be too early to implement a particular PODRPM in clinical practice with confidence.

Review Meta Analysis
Causes and prevalence of unplanned readmissions after colorectal surgery: a systematic review and meta-analysis.
A systematic review and meta-analysis of the current literature was conducted to compare the overall and cause-specific readmission rates after colorectal surgery of older adults with those of younger individuals. Potential predictors of unplanned readmission were also identified. Estimated pooled readmission rates were calculated and reported as pooled proportions with associated 95% confidence intervals (CI) in 60,131 total readmissions; 11.0% (95% CI = 10.0-12.0) of all admissions after colorectal surgery resulted in unplanned readmission at 30 days. ⋯ Bowel obstruction was the most common cause of unplanned readmission, accounting for 33.4% of all unplanned readmissions, followed by surgical site infection (15.7%) and intraabdominal abscess (12.6%). Several age-related predictors of unplanned readmission were identified, such as poor functional capacity, multiple comorbidities, chronic obstructive pulmonary disease, and discharge to a nonhome destination. The findings of this review will help guide the development of future interventions to reduce preventable readmissions after colorectal surgery in older adults.

Review Meta Analysis
Outcomes associated with opioid use in the treatment of chronic noncancer pain in older adults: a systematic review and meta-analysis.
This systematic review summarizes existing evidence regarding the efficacy, safety, and abuse and misuse potential of opioids as treatment for chronic noncancer pain in older adults. Multiple databases were searched to identify relevant studies published in English (1/1/80-7/1/09) with a mean study population age of 60 and older. Forty-three articles were identified and retained for review (40 reported safety and efficacy data, the remaining 3 reported misuse or abuse outcome data). ⋯ Abuse and misuse behaviors were negatively associated with older age. In older adults with chronic pain and no significant comorbidity, short-term use of opioids is associated with reduction in pain intensity and better physical functioning but poorer mental health functioning. The long-term safety, efficacy, and abuse potential of this treatment practice in diverse populations of older persons remain to be determined.

To assess the association between use of clinical pathways for hip fracture and changes in the rates of five inpatient complications and short-term mortality. ⋯ An association was observed between clinical pathway use and lower odds of four common complications of hospitalization after hip fracture; only a small, statistically insignificant association was observed between pathway use and changes in short-term mortality, suggesting that assessments of hospital quality based on short-term mortality may not reflect important improvements in patient outcomes that hospitals may achieve using clinical pathways.
