Standardized total knee arthroplasty pathway improves outcomes in minority patients.

OBJECTIVES: Inferior total knee arthroplasty (TKA) outcomes are reported in minority populations. Standardized TKA pathways improve outcomes but have not been studied extensively in minority populations. This study evaluated the impact of TKA pathway standardization at an urban teaching hospital that predominantly treats minority patients. STUDY DESIGN: Retrospective cohort study. METHODS: This study compared primary TKA outcomes before and after implementation of a standardized multidisciplinary pathway that emphasized preoperative education and discharge planning, preemptive multimodal pain control, and early rehabilitation. Patients were grouped as "nonpathway" (n = 144) or "pathway" (n = 182) based on whether they underwent TKA before or after pathway implementation. Outcomes included length of stay (LOS), patient-controlled analgesia (PCA) use, blood transfusion, postoperative hemoglobin, complications, and discharge disposition. Analysis involved negative binomial and multiple logistic regression models, t tests, and Fisher's exact tests. RESULTS: Mean (SD) age was 61.6 (8.7) years, and 36.5% were men. Ethnicity of the patients included Hispanic (44.5%), African American (27.9%), Asian (14.1%), and White (12.9%). Pathway and nonpathway patients were similar demographically and racially. Pathway patients had shorter LOS (P = .04), less PCA use (P < .001), more frequent discharge home (P = .03), fewer transfusions (P = .002), and higher postoperative hemoglobin (P < .001). Overall incidence of complications was similar (P = .61). Nonpathway patients developed more cardiopulmonary complications (P = .02), whereas pathway patients had more wound dehiscence (P = .01). CONCLUSIONS: Compared with nonpathway patients, standardized TKA pathway patients had shorter LOS, decreased PCA use, increased discharge to home, fewer blood transfusions, and higher postoperative hemoglobin, with no difference in total incidence of complication.

Prevalence of Central Nervous System Polypharmacy and Associations with Overdose and Suicide-Related Behaviors in Iraq and Afghanistan War Veterans in VA Care 2010-2011.

BACKGROUND: The increase in the quantities of central nervous system (CNS)-acting medications prescribed has coincided with increases in overdose mortality, suicide-related behaviors, and unintentional deaths in military personnel deployed in support of the wars in Iraq and Afghanistan. Data on the extent and impact of prescribing multiple CNS drugs among Iraq and Afghanistan Veterans (IAVs) are sparse. OBJECTIVES: We sought to identify the characteristics of IAVs with CNS polypharmacy and examine the association of CNS polypharmacy with drug overdose and suicide-related behaviors controlling for known risk factors. METHODS: This cross-sectional cohort study examined national data of Iraq and Afghanistan Veterans (N = 311,400) who used the Veterans Health Administration (VHA) during the fiscal year 2011. CNS polypharmacy was defined as five or more CNS-acting medications; drug/alcohol overdose and suicide-related behaviors were identified using ICD-9-CM codes. Demographic and clinical characteristics associated with CNS polypharmacy were identified using a multivariable logistic regression model. RESULTS: We found that 25,546 (8.4 %) of Iraq and Afghanistan Veterans had CNS polypharmacy. Those with only post-traumatic stress disorder (PTSD) (adjusted odds ratio (AOR) 6.50, 99 % confidence interval (CI) 5.96-7.10), only depression (AOR 6.42, 99 % CI 5.86-7.04), co-morbid PTSD and depression (AOR 12.98, 99 % CI 11.97-14.07), and co-morbid traumatic brain injury (TBI), PTSD, and depression (AOR 15.30, 99 % CI 14.00-16.73) had the highest odds of CNS polypharmacy. After controlling for these co-morbid conditions, CNS polypharmacy was significantly associated with drug/alcohol overdose and suicide-related behavior. CONCLUSION: CNS polypharmacy was most strongly associated with PTSD, depression, and TBI, and independently associated with overdose and suicide-related behavior after controlling for known risk factors. These findings suggest that CNS polypharmacy may be used as an indicator of risk for adverse outcomes. Further research should evaluate whether CNS polypharmacy may be used as a trigger for evaluation of the current care provided to these individuals.
