Cardiac Performance Measure Compliance in Outpatients The American College of Cardiology and National Cardiovascular Data Registry's PINNACLE (Practice Innovation And Clinical Excellence) Program

ObjectivesWe examined compliance with performance measures for 14,464 patients enrolled from July 2008 through June 2009 into the American College of Cardiology's PINNACLE (Practice Innovation And Clinical Excellence) program to provide initial insights into the quality of outpatient cardiac care.BackgroundLittle is known about the quality of care of outpatients with coronary artery disease (CAD), heart failure, and atrial fibrillation, and whether sex and racial disparities exist in the treatment of outpatients.MethodsThe PINNACLE program is the first, national, prospective office-based quality improvement program of cardiac patients designed, in part, to capture, report, and improve outpatient performance measure compliance. We examined the proportion of patients whose care was compliant with established American College of Cardiology, American Heart Association, and American Medical Association-Physician Consortium for Performance Improvement (ACC/AHA/PCPI) performance measures for CAD, heart failure, and atrial fibrillation.ResultsThere were 14,464 unique patients enrolled from 27 U.S. practices, accounting for 18,021 clinical visits. Of these, 8,132 (56.4%) had CAD, 5,012 (34.7%) had heart failure, and 2,786 (19.3%) had nonvalvular atrial fibrillation. Data from the PINNACLE program were feasibly collected for 24 of 25 ACC/AHA/PCPI performance measures. Compliance with performance measures ranged from being very low (e.g., 13.3% of CAD patients screened for diabetes mellitus) to very high (e.g., 96.7% of heart failure patients with blood pressure assessments), with moderate (70% to 90%) compliance observed for most performance measures. For 3 performance measures, there were small differences in compliance rates by race or sex.ConclusionsFor more than 14,000 patients enrolled from 27 practices in the outpatient PINNACLE program, we found that compliance with performance measures was variable, even after accounting for exclusion criteria, suggesting an important opportunity to improve the quality of outpatient care

Heart failure after treatment for breast cancer

Background: We aimed to develop dose–response relationships for heart failure (HF) following radiation and anthracyclines in breast cancer treatment, and to assess HF associations with trastuzumab and endocrine therapies. Methods and results: A case–control study was performed within a cohort of breast cancer survivors treated during 1980–2009. Cases (n = 102) had HF as first cardiovascular diagnosis and were matched 1:3 on age and date of diagnosis. Individual cardiac radiation doses were estimated, and anthracycline doses and use of trastuzumab and endocrine therapy were abstracted from oncology notes. For HF cases who received radiotherapy, the estimated median mean heart dose (MHD) was 6.8 Gy [interquartile range (IQR) 0.9–13.7]. MHD was not associated with HF risk overall [excess rate ratio (ERR) = 1%/Gy, 95% confidence interval (CI) −2 to 10]. In patients treated with anthracyclines, exposure of ≥20% of the heart to ≥20 Gy was associated with a rate ratio of 5.7 (95% CI 1.7–21.7) compared to <10% exposed to ≥20 Gy. For cases who received radiotherapy, median cumulative anthracycline dose was 247 mg/m2 (IQR 240–319). A dose-dependent increase was observed after anthracycline without trastuzumab (ERR = 1.5% per mg/m2, 95% CI 0.5–4.1). After anthracycline and trastuzumab, the rate ratio was 34.9 (95% CI 11.1–110.1) compared to no chemotherapy. Conclusions: In absence of anthracyclines, breast cancer radiotherapy was not associated with increased HF risk. Strongly elevated HF risks were observed after treatment with anthracyclines and also after treatment with trastuzumab. The benefits of these systemic treatments usually exceed the risks of HF, but our results emphasize the need to support ongoing efforts to evaluate preventative strategies

Adjuvant and neoadjuvant breast cancer treatments: A systematic review of their effects on mortality

Background Adjuvant and neoadjuvant breast cancer treatments can reduce breast cancer mortality but may increase mortality from other causes. Information regarding treatment benefits and risks is scattered widely through the literature. To inform clinical practice we collated and reviewed the highest quality evidence. Methods Guidelines were searched to identify adjuvant or neoadjuvant treatment options recommended in early invasive breast cancer. For each option, systematic literature searches identified the highest-ranking evidence. For radiotherapy risks, searches for dose-response relationships and modern organ doses were also undertaken. Results Treatment options recommended in USA and elsewhere included chemotherapy (anthracycline, taxane, platinum, capecitabine), anti-human epidermal growth factor 2 therapy (trastuzumab, pertuzumab, trastuzumab emtansine, neratinib), endocrine therapy (tamoxifen, aromatase inhibitor, ovarian ablation/suppression with varying durations) and bisphosphonates. Radiotherapy options were after breast conserving surgery (whole breast, partial breast, tumour bed boost, regional nodes) and after mastectomy (chest wall, regional nodes). Treatment options were supported by randomised evidence, including >10,000 women for eight treatment comparisons, 1,000-10,000 for fifteen and <1,000 for one. Most treatment comparisons reduced breast cancer mortality or recurrence by 10-25%, with no increase in non-breast-cancer death. Anthracycline chemotherapy and radiotherapy increased overall non-breast-cancer mortality. Anthracycline risk was from heart disease and leukaemia. Radiation-risks were mainly from heart disease, lung cancer and oesophageal cancer, and increased with increasing heart, lung and oesophagus radiation doses respectively. Taxanes increased leukaemia risk. Aromatase inhibitors in premenopausal women increased death from second cancers. Conclusions These benefits and risks inform treatment decisions for individuals and recommendations for groups of women

Radiotherapy to regional nodes in early breast cancer: an individual patient data meta-analysis of 14324 women in 16 trials

BackgroundRadiotherapy has become much better targeted since the 1980s, improving both safety and efficacy. In breast cancer, radiotherapy to regional lymph nodes aims to reduce risks of recurrence and death. Its effects have been studied in randomised trials, some before the 1980s and some after. We aimed to assess the effects of regional node radiotherapy in these two eras.MethodsIn this meta-analysis of individual patient data, we sought data from all randomised trials of regional lymph node radiotherapy versus no regional lymph node radiotherapy in women with early breast cancer (including one study that irradiated lymph nodes only if the cancer was right-sided). Trials were identified through the EBCTCG's regular systematic searches of databases including MEDLINE, Embase, the Cochrane Library, and meeting abstracts. Trials were eligible if they began before Jan 1, 2009. The only systematic difference between treatment groups was in regional node radiotherapy (to the internal mammary chain, supraclavicular fossa, or axilla, or any combinations of these). Primary outcomes were recurrence at any site, breast cancer mortality, non-breast-cancer mortality, and all-cause mortality. Data were supplied by trialists and standardised into a format suitable for analysis. A summary of the formatted data was returned to trialists for verification. Log-rank analyses yielded first-event rate ratios (RRs) and confidence intervals.FindingsWe found 17 eligible trials, 16 of which had available data (for 14 324 participants), and one of which (henceforth excluded), had unavailable data (for 165 participants). In the eight newer trials (12 167 patients), which started during 1989–2008, regional node radiotherapy significantly reduced recurrence (rate ratio 0·88, 95% CI 0·81–0·95; p=0·0008). The main effect was on distant recurrence as few regional node recurrences were reported. Radiotherapy significantly reduced breast cancer mortality (RR 0·87, 95% CI 0·80–0·94; p=0·0010), with no significant effect on non-breast-cancer mortality (0·97, 0·84–1·11; p=0·63), leading to significantly reduced all-cause mortality (0·90, 0·84–0·96; p=0·0022). In an illustrative calculation, estimated absolute reductions in 15-year breast cancer mortality were 1·6% for women with no positive axillary nodes, 2·7% for those with one to three positive axillary nodes, and 4·5% for those with four or more positive axillary nodes. In the eight older trials (2157 patients), which started during 1961–78, regional node radiotherapy had little effect on breast cancer mortality (RR 1·04, 95% CI 0·91–1·20; p=0·55), but significantly increased non-breast-cancer mortality (1·42, 1·18–1·71; p=0·00023), with risk mainly after year 20, and all-cause mortality (1·17, 1·04–1·31; p=0·0067).InterpretationRegional node radiotherapy significantly reduced breast cancer mortality and all-cause mortality in trials done after the 1980s, but not in older trials. These contrasting findings could reflect radiotherapy improvements since the 1980s.<br/
