A Lack of Decline in Major Nontraumatic Amputations in Texas: Contemporary Trends, Risk Factor Associations, and Impact of Revascularization.

ABSTRACT: OBJECTIVE:Nontraumatic major lower extremity amputations (LEAs) have been reported to be declining nationally; however, trends in Texas have been less well described. We evaluated demographic and clinical risk factors and revascularization associations for LEAs by using inpatient hospital discharge data in Texas from 2005 to 2014. RESEARCH DESIGN AND METHODS:Inpatient hospital discharge data were obtained from the Texas Center for Health Statistics. Multivariate logistic regression analyses were performed to evaluate clinical, ethnic, and socioeconomic risk factors associated with LEA. The impact of revascularization (surgical and/or endovascular) on LEA was analyzed. RESULTS:Between 2005 and 2014, of 19,939,716 admissions, 46,627 were for nontraumatic major LEAs. Over time, LEAs were constant, and revascularization rates during index admission declined. The majority of LEAs occurred in males and in individuals aged 60-79 years. Risk factors associated with LEA included diabetes, peripheral arterial disease, chronic kidney disease, and male sex (P < 0.001). Insurance status, hyperlipidemia, coronary artery disease, and stroke/transient ischemic attack were associated with lower odds of amputation (P < 0.001). Hispanic (odds ratio [OR] 1.51 [95% CI 1.48, 1.55], P < 0.001) and black (OR 1.97 [95% CI 1.92, 2.02], P < 0.001) ethnicities were associated with a higher risk for amputation when compared with non-Hispanic whites. Revascularization, either surgical or endovascular (OR 0.52 [95% CI 0.5, 0.54], P < 0.001), was also associated with lower odds for amputation. CONCLUSIONS:Amputation rates in Texas have remained constant, whereas revascularization rates are declining. A higher risk for LEA was seen in minorities, including Hispanic ethnicity, which is the fastest growing demographic in Texas. Revascularization and having insurance were associated with lower odds for amputation.

Project description:INTRODUCTION:Recent studies indicate that death certificate-based single-cause-of-death diagnoses can substantially underestimate the contribution of sepsis to mortality in the general population and among maternal decedents. There are no population-based data in the United States on the patterns of the contribution of sepsis to pregnancy-associated deaths. METHODS:We studied the Texas Inpatient Public Use Data File to identify pregnancy-associated hospitalizations with reported hospital death during 2001-2010. We then examined the annual reporting of sepsis, and that of other reported most common causes of maternal death, including hemorrhage, embolism, preeclampsia/eclampsia, cardiovascular conditions, cardiomyopathy, cerebrovascular accidents, and anesthesia complications. The annual rate of sepsis among decedents, its trend over time, and changes of its annual rank among other examined potential causes of maternal death were assessed. RESULTS:There were 557 pregnancy-associated hospital deaths during study period. Sepsis was reported in 131 (23.5%) decedents. Sepsis has been increasingly reported among decedents, rising by 9.1%/year (P = 0.0025). The rank of sepsis, as compared to the other examined potential causes of maternal death rose from the 5th in 2001 to 1st since 2008. At the end of the last decade, sepsis has been reported in 28.1% of pregnancy-associated deaths. More than one potential cause of maternal death was reported in 39% of decedents. CONCLUSION:Sepsis has become the most commonly reported potential cause of death among maternal decedents in the present cohort, noted in over 1 in 4 fatal hospitalizations by the end of the last decade. Although causality cannot be inferred from administrative data, given its known contribution to maternal death, it is likely that sepsis plays an increasing role in fatal maternal hospital outcomes. The prevalent co-reporting of multiple potential causes of maternal death in the present cohort underscores the complexity of determining the sources of evolving rise of maternal mortality.

Project description:Coronary revascularization is among the most common hospital-based major interventional procedures performed in the United States. It is uncertain how new revascularization technologies, new clinical evidence from trials, and updated clinical guidelines have influenced the volume and distribution of coronary revascularizations over the past decade.To examine national time trends in the rates and types of coronary revascularizations.A serial cross-sectional study with time trends of patients undergoing coronary artery bypass graft (CABG) surgery or percutaneous coronary interventions (PCIs) between 2001 and 2008 at US hospitals in the Healthcare Cost and Utilization Project's Nationwide Inpatient Sample, which reports inpatient coronary revascularizations. These data were supplemented by Medicare outpatient hospital claims.Annual procedure rates of coronary revascularizations, CABG surgery, and PCI.A 15% decrease (P < .001) in the annual rate of coronary revascularizations was observed from 2001-2002 to 2007-2008. The annual CABG surgery rate decreased steadily from 1742 (95% confidence interval [CI], 1663-1825) CABG surgeries per million adults per year in 2001-2002 to 1081 (95% CI, 1032-1133) CABG surgeries per million adults per year in 2007-2008 (P < .001), but PCI rates did not significantly change (3827 [95% CI, 3578-4092] PCI per million adults per year in 2001-2002 vs 3667 [95% CI, 3429-3922] PCI per million adults per year in 2007-2008, P = .74). Between 2001 and 2008, the number of hospitals in the Nationwide Inpatient Sample providing CABG surgery increased by 12% (212 in 2001 vs 241 in 2008, P = .03), and the number of PCI hospitals increased by 26% (246 in 2001 vs 331 in 2008, P < .001). The median CABG surgery caseload per hospital decreased by 28% (median [interquartile range], 253 [161-458] in 2001 vs 183 [98-292] in 2008; P < .001) and the number of CABG surgery hospitals providing fewer than 100 CABG surgeries per year increased from 23 (11%) in 2001 to 62 (26%) in 2008 (P < .001).In US hospitals between 2001 and 2008, a substantial decrease in CABG surgery utilization rates was observed, but PCI utilization rates remained unchanged.

Project description:ObjectiveTo determine trends in amputations and revascularizations for peripheral artery disease (PAD) in a well-defined population.MethodsA population-based cohort study of Olmsted County, Minnesota, residents with PAD undergoing amputation or revascularization was conducted between January 1, 1990, and December 31, 2009. Population-level 5-year incidence trends for endovascular, open surgical, and hybrid revascularizations and major and minor amputations were determined. Limb-specific outcomes after revascularization, including major adverse limb events and amputation-free survival, were compared between initial surgical and endovascular or hybrid revascularization groups using Kaplan-Meier analysis.ResultsWe identified 773 residents who underwent 1906 limb-procedures, including 689 open revascularizations, 685 endovascular or hybrid revascularizations, and 220 major amputations. During the 20-year study period, the incidence of endovascular and hybrid revascularizations increased, whereas the incidence of open surgical revascularizations and major amputations decreased. Incidence of revascularizations for chronic limb-threatening ischemia (CLTI) did not change. Among residents with CLTI undergoing their first revascularization on a limb, endovascular revascularization was associated with more major adverse limb events and major amputations compared with surgical revascularization during the ensuing 15 years.ConclusionThe rising incidence of endovascular and hybrid revascularizations and the decreasing incidence of open surgical revascularizations for PAD were associated with a decreasing incidence of major amputations in this population between 1990 and 2009, despite a stable incidence of revascularizations for CLTI. With more major adverse limb events and major amputations after endovascular revascularization, these trends suggest that additional emphasis should be placed on improving limb salvage efforts beyond just mode of revascularization.
