Determining the factors associated with a prolonged length of stay for adolescent idiopathic scoliosis patients undergoing posterior spinal instrumentation and fusion in a single-payer health care system: are these factors different than those in the United States?

INTRODUCTION: Rapid recovery pathways (RRP) for adolescent idiopathic scoliosis patients undergoing posterior spinal instrumentation and fusion (PSIF) have been shown to be successful in reducing hospital length of stay (LOS). Although the majority of patients are discharged within 3 days, some patients require longer hospital admission. Previous studies in the United States have identified predictors of prolonged LOS for this patient population. The goal of this project was to determine if these predictors are the same for Canadian scoliosis patients and to identify those features which are different under this single-payer system. METHODS: A RRP for scoliosis surgery was implemented in March 2015 at a single, tertiary referral children's hospital in Canada. Previously identified features, along with numerous other patient factors, were collected. Spearman correlations were used to determine the factors most associated with hospital LOS and those factors were used in a multivariable regression model. RESULTS: A total of 161 patients were included in the analysis. Of the previously identified patient factors, only receiving a peri-operative transfusion was found to be significant (ρ = 0.24; p = 0.002). None of the other pre-identified variables were found to be significantly correlated with LOS. Variables not previously examined that were found to be significantly correlated with hospital LOS included ASA status (ρ = 0.19, p = 0.046), fusion involving both the thoracic and lumbar spine (ρ = 0.18, p = 0.025), and receiving celecoxib on post-operative day 1 (ρ = - 0.16; p = 0.038). The features that had the greatest association with LOS through multivariable regression was receiving a blood transfusion (B = 0.48; 95%CI 0.096-0.89; p = 0.017). CONCLUSIONS: In this study, we found that many of the features found to be significantly correlated with prolonged hospital LOS in the United States are not transferable to the Canadian healthcare system. This is important for the Canadian, and other surgeons in a single-payer system, in order to identify pre-operative or immediate post-operative factors that may extend patient LOS following PSIF and plan resources accordingly.

Examining the Family Support Role of Older Hispanics, African Americans, and Non-Hispanic Whites and Their Breast Cancer Screening Behaviors.

Disparities in breast cancer mortality rates among older Black and Hispanic women are due in part to low participation in cancer screening. Participation in cancer screening could be affected by an array of factors, including social support. Understanding the complex interplay between social support and breast cancer screening among older female adults, specifically among groups with higher mortality rates, is extremely important for timely and appropriate interventions to increase survival rates. Thus, utilizing the social network theory as the conceptual framework, this study aims to examine effects of social support on receiving a mammogram among a representative sample of older adults, specifically African American and Hispanic populations in the United States. Logistic regression models were conducted using the 2008 and 2012 Health and Retirement Study data. Findings from this study indicate that specific aspects of social support influence breast cancer screening participation among older Hispanic and non-Hispanic White women. However, this was not the case for the older Black women after adjusting for the sociodemographic factors. Given the role that family members play in the care of older adults, it is critical that social workers consider both the possible positive and negative interactions older women may have and how these interactions may affect their cancer screening behaviors. Findings can provide formative data to develop public health and social work interventions to increase positive social support and reduce negative social support by spouses and children to enhance breast cancer screening among older adults.
