ABSTRACT

AIMS: To examine the association between cumulative missed opportunities for care (CMOC) and mortality in patients with ST-elevation myocardial infarction (STEMI). METHODS: A cohort study of 112,286 STEMI patients discharged from hospital alive between January 2007 and December 2010, using data from the Myocardial Ischaemia National Audit Project (MINAP). A CMOC score was calculated for each patient and included: pre-hospital ECG, acute use of aspirin, timely reperfusion, prescription at hospital discharge of aspirin, thienopyridine inhibitor, ACE-inhibitor (or equivalent), HMG-CoA reductase inhibitor and ß-blocker, and referral for cardiac rehabilitation. Mixed-effects logistic regression models evaluated the effect of CMOC on risk-adjusted 30-day and 1-year mortality (RAMR). RESULTS: 44.5% of patients were ineligible for ≥1 care component. Of patients eligible for all nine components, 50.6% missed ≥1 opportunity. Pre-hospital ECG and timely reperfusion were most frequently missed, predicting further missed care at discharge (pre-hospital ECG incident rate ratio [95% CI]: 1.64 [1.58-1.70]; timely reperfusion 9.94 [9.51-10.40]). Patients ineligible for care had higher RAMR than those eligible for care (30-days: 1.7% vs. 1.1%; 1-year: 8.6% vs. 5.2%), whilst those with no missed care had lower mortality than patients with ≥4 CMOC (30-days: 0.5% vs. 5.4%, adjusted OR (aOR) per CMOC group 1.22, 95% CI: 1.05-1.42; 1-year: 3.2% vs. 22.8%, aOR 1.23, 1.13-1.34). CONCLUSIONS: Opportunities for care in STEMI are commonly missed and significantly associated with early and later mortality. Thus, outcomes after STEMI may be improved by greater attention to missed opportunities to eligible care.

ABSTRACT

BACKGROUND: Hospital acute myocardial infarction (AMI) care is increasingly evaluated using composite quality scores. We investigated the influence of three aggregation methods for an AMI indicator on mortality and hospital rank. METHODS AND RESULTS: We studied 136,392 patients discharged alive from 199 hospitals with AMI recorded in the Myocardial Ischaemia National Audit Project, between 01/01/2008 and 31/12/2009. A composite of prescription of aspirin, thienopyridine inhibitor, ß-blocker, angiotensin converting enzyme inhibitor, HMG CoA reductase enzyme inhibitor and enrolment in cardiac rehabilitation at discharge was aggregated as opportunity based (OBCS), weighted opportunity-based (WOBCS) and all-or-nothing (ANCS) scores. We quantified adjusted 30-day, 6-month and 1-year mortality rates and hospital performance rank. Median (IQR) scores were OBCS: 95.0% (3.5), WOBCS: 94.7% (0.8) and ANCS: 80.9% (11.8). The three methods affected the proportion of hospitals outside 99.8% credible limits of the national median (OBCS: 52.2%, WOBCS: 64.3% and ANCS: 37.7%) and hospital rank. Each 1% increase in composite score was significantly associated with a 1 to 3% and a 4% reduction in 6-month and 1-year mortality, respectively. However, the ANCS had fewer cases and no significant association with 30-day mortality. CONCLUSIONS: A hospital composite score, incorporating 6 aspects of AMI care, was significantly inversely associated with mortality. However, composite aggregation method influenced hospital rank, number of cases available for analysis and size of the association with all-cause mortality, with the ANCS performing least well. The use and choice of composite scores in hospital AMI quality improvement requires careful evaluation.

ABSTRACT

BACKGROUND: Mortality rates after acute myocardial infarction (AMI) have declined, but there is uncertainty regarding the extent of improvements in early mortality in the elderly. METHODS: Mixed-effects regression analysis of 30-day mortality using data from 478,242 patients with AMI at 215 hospitals in England and Wales stratified by STEMI/NSTEMI, sex, and age group. A hospital opportunity-based composite score (OBCS) for aspirin, ACE-inhibitor, statin, ß blocker, and referral for cardiac rehabilitation was used as measure of quality of hospital care. RESULTS: 30-day mortality rates (95% CI) fell from 10.7% (10.6 to 10.9%) in 2004/5 to 8.4% (8.3 to 8.6%) in 2008/9. The median (IQR) hospital OBCSs increased over time, 2004/5: 87.3 (7.2), 2006/7: 88.9 (6.3), 2008/9: 90.3 (6.1), P<0.001, and were similar between age groups (18 to <65 years, 65 to 79 years, and ≥ 80 years) for STEMI: 89.4 (6.5) vs. 89.4 (6.6), vs. 89.2 (6.5) and NSTEMI: 88.6 (7.3) vs. 88.8 (7.0) vs. 88.9 (7.0), respectively For males, all age groups except patients <65 years demonstrated a significant decrease in adjusted mortality. For females, only patients ≥ 80 years demonstrated a significant reduction in adjusted mortality. A 1% increase in hospital OBCS was associated with a 1% decrease in 30-day mortality (95% CI: 0.99 to 0.99, P<0.001). CONCLUSION: In England and Wales, for patients with AMI there are age and sex-dependent differences in improvements in 30-day mortality. Whereas young males with AMI have reached an acceptable performance plateau, all other groups are either improving or, more importantly, are yet to demonstrate this.

ABSTRACT

AIMS: To examine age-dependent in-hospital mortality for hospitalization with acute coronary syndromes (ACS) in England and Wales. METHODS AND RESULTS: Mixed-effects regression analysis using data from 616 011 ACS events at 255 hospitals as recorded in the Myocardial Ischemia National Audit Project (MINAP) 2003-2010; 102 415 (16.7%) patients were aged <55 years and 72 721 (11.9%) ≥85 years. Patients ≥85 years with ST-elevation myocardial infarction (STEMI) were less likely to receive emergency reperfusion therapy than those <55 years (RR = 0.27, 95% CI: 0.25-0.28). Older patients had greater lengths of stay (P< 0.001) and higher in-hospital mortality (P< 0.001). For STEMI and non-ST-elevation myocardial infarction (NSTEMI), there were reductions in in-hospital mortality from 2003 to 2010 across all age groups including the very elderly. For STEMI ≥ 85 years, in-hospital mortality reduced from 30.1% in 2003 to 19.4% in 2010 (RR = 0.54, 95% CI: 0.38-0.75, P< 0.001), and for NSTEMI ≥ 85 years, from 31.5% in 2003 to 20.4% in 2010 (RR = 0.56, 95% CI: 0.42-0.73, P< 0.001). Findings were upheld after multi-level adjustment (base = 2003): male STEMI 2010 OR = 0.60, 95% CI: 0.48-0.75; female STEMI 2010 OR = 0.55, 95% CI: 0.42-0.71; male NSTEMI OR = 0.50, 95% CI: 0.42-0.60; female NSTEMI OR = 0.49, 95% CI: 0.40-0.59. CONCLUSION: For patients hospitalized with ACS in England and Wales, there have been substantial reductions in in-hospital mortality rates from 2003 to 2010 across all age groups. The temporal improvements in mortality were similar for sex and type of acute myocardial infarction. Age-dependent inequalities in the management of ACS were apparent.

ABSTRACT

We report what is believed to be the first case of late-onset prosthetic valve endocarditis caused by Mycoplasma hominis in a case of blood culture-negative endocarditis. The objective of this report is to emphasize the use of a broad-range PCR technique for bacterial 16S rRNA genes in identifying the causative pathogen, thus enabling targeted antimicrobial treatment.
