Decreasing Trends in Road Traffic Injury Incidence and Mortality in Nigeria: A Ten-Year Analysis.

BACKGROUND: Road traffic accidents constitute a significant public health burden in Nigeria. In this study, we aim to (1) characterize the temporal burden of road traffic injury (RTI) and mortality rates in Nigeria over a decade, (2) identify regional RTI incidence, mortality trends, and high-risk regions, and (3) assess the impact of state population on injury and mortality. MATERIALS AND METHODS: We retrospectively reviewed aggregate state-level RTI incidence and mortality counts reported by the Federal Road Safety Corps from January 2001 through December 2010. We also reviewed population data from the National Population Commission. In addition to national analyses, regional analyses were performed in Nigeria's six geopolitical zones and one Federal Capital Territory (FCT). Regression analysis was also performed to determine the relationship between population and RTI incidence and mortality. RESULTS: The national median RTI incidence and mortality rates declined by 53% and 75%, respectively, between 2001 and 2010. Analysis by geopolitical zone yielded the greatest increases for both injury and mortality in the FCT and the greatest decreases for both in the South-South region. The average geopolitical zone, apart from the FCT, experienced a 24% decrease in the incidence rate and a 69% decrease in the mortality rate. An analysis of variance, run to assess potential differences in RTI incidence and mortality rates by state population, yielded significant values of P = 0.0023 for injury and P = 0.0002 for mortality. CONCLUSIONS: Acknowledging the potential for underreporting, a more holistic surveillance approach would generate more accurate data for future policy creation to improve clinical outcomes.

National patterns of risk-standardized mortality and readmission after hospitalization for acute myocardial infarction, heart failure, and pneumonia: update on publicly reported outcomes measures based on the 2013 release.

BACKGROUND: The Centers for Medicare & Medicaid Services publicly reports risk-standardized mortality rates (RSMRs) within 30-days of admission and, in 2013, risk-standardized unplanned readmission rates (RSRRs) within 30-days of discharge for patients hospitalized with acute myocardial infarction (AMI), heart failure (HF), and pneumonia. Current publicly reported data do not focus on variation in national results or annual changes. OBJECTIVE: Describe U.S. hospital performance on AMI, HF, and pneumonia mortality and updated readmission measures to provide perspective on national performance variation. DESIGN: To identify recent changes and variation in national hospital-level mortality and readmission for AMI, HF, and pneumonia, we performed cross-sectional panel analyses of national hospital performance on publicly reported measures. PARTICIPANTS: Fee-for-service Medicare and Veterans Health Administration beneficiaries, 65 years or older, hospitalized with principal discharge diagnoses of AMI, HF, or pneumonia between July 2009 and June 2012. RSMRs/RSRRs were calculated using hierarchical logistic models risk-adjusted for age, sex, comorbidities, and patients' clustering among hospitals. RESULTS: Median (range) RSMRs for AMI, HF, and pneumonia were 15.1% (9.4-21.0%), 11.3% (6.4-17.9%), and 11.4% (6.5-24.5%), respectively. Median (range) RSRRs for AMI, HF, and pneumonia were 18.2% (14.4-24.3%), 22.9% (17.1-30.7%), and 17.5% (13.6-24.0%), respectively. Median RSMRs declined for AMI (15.5% in 2009-2010, 15.4% in 2010-2011, 14.7% in 2011-2012) and remained similar for HF (11.5% in 2009-2010, 11.9% in 2010-2011, 11.7% in 2011-2012) and pneumonia (11.8% in 2009-2010, 11.9% in 2010-2011, 11.6% in 2011-2012). Median hospital-level RSRRs declined: AMI (18.5% in 2009-2010, 18.5% in 2010-2011, 17.7% in 2011-2012), HF (23.3% in 2009-2010, 23.1% in 2010-2011, 22.5% in 2011-2012), and pneumonia (17.7% in 2009-2010, 17.6% in 2010-2011, 17.3% in 2011-2012). CONCLUSIONS: We report the first national unplanned readmission results demonstrating declining rates for all three conditions between 2009-2012. Simultaneously, AMI mortality continued to decline, pneumonia mortality was stable, and HF mortality experienced a small increase.

National performance on door-in to door-out time among patients transferred for primary percutaneous coronary intervention.

BACKGROUND: Delays in treatment time are commonplace for patients with ST-segment elevation acute myocardial infarction who must be transferred to another hospital for percutaneous coronary intervention. Experts have recommended that door-in to door-out (DIDO) time (ie, time from arrival at the first hospital to transfer from that hospital to the percutaneous coronary intervention hospital) should not exceed 30 minutes. We sought to describe national performance in DIDO time using a new measure developed by the Centers for Medicare & Medicaid Services. METHODS: We report national median DIDO time and examine associations with patient characteristics (age, sex, race, contraindication to fibrinolytic therapy, and arrival time) and hospital characteristics (number of beds, geographic region, location [rural or urban], and number of cases reported) using a mixed effects multivariable model. RESULTS: Among 13,776 included patients from 1034 hospitals, only 1343 (9.7%) had a DIDO time within 30 minutes, and DIDO exceeded 90 minutes for 4267 patients (31.0%). Mean estimated times (95% CI) to transfer based on multivariable analysis were 8.9 (5.6-12.2) minutes longer for women, 9.1 (2.7-16.0) minutes longer for African Americans, 6.9 (1.6-11.9) minutes longer for patients with contraindication to fibrinolytic therapy, shorter for all age categories (except >75 years) relative to the category of 18 to 35 years, 15.3 (7.3-23.5) minutes longer for rural hospitals, and 14.4 (6.6-21.3) minutes longer for hospitals with 9 or fewer transfers vs 15 or more in 2009 (all P < .001). CONCLUSION: Among patients presenting to emergency departments and requiring transfer to another facility for percutaneous coronary intervention, the DIDO time rarely met the recommended 30 minutes.
