    Input: CONTEXT Comprehensive discharge planning by advanced practice nurses has demonstrated short-term reductions in readmissions of elderly patients , but the benefits of more intensive follow-up of hospitalized elders at risk for poor outcomes after discharge has not been studied . OBJECTIVE To examine the effectiveness of an advanced practice nurse-centered discharge planning and home follow-up intervention for elders at risk for hospital readmissions .  DESIGN R and omized clinical trial with follow-up at 2 , 6 , 12 , and 24 weeks after index hospital discharge . SETTING Two urban , academically affiliated hospitals in Philadelphia , Pa. PARTICIPANTS Eligible patients were 65 years or older , hospitalized between August 1992 and March 1996 , and had 1 of several medical and surgical reasons for admission . INTERVENTION Intervention group patients received a comprehensive discharge planning and home follow-up protocol design ed specifically for elders at risk for poor outcomes after discharge and implemented by advanced practice nurses . MAIN OUTCOME MEASURES Readmissions , time to first readmission , acute care visits after discharge , costs , functional status , depression , and patient satisfaction . RESULTS A total of 363 patients ( 186 in the control group and 177 in the intervention group ) were enrolled in the study ; 70 % of intervention and 74 % of control subjects completed the trial . Mean age of sample was 75 years ; 50 % were men and 45 % were black . By week 24 after the index hospital discharge , control group patients were more likely than intervention group patients to be readmitted at least once ( 37.1 % vs 20.3 % ; P<.001 ) . Fewer intervention group patients had multiple readmissions ( 6.2 % vs 14.5 % ; P = .01 ) and the intervention group had fewer hospital days per patient ( 1.53 vs 4.09 days ; P<.001 ) . Time to first readmission was increased in the intervention group ( P<.001 ) . At 24 weeks after discharge , total Medicare reimbursements for health services were about $ 1.2 million in the control group vs about $ 0.6 million in the intervention group ( P<.001 ) . There were no significant group differences in post-discharge acute care visits , functional status , depression , or patient satisfaction . CONCLUSIONS An advanced practice nurse-centered discharge planning and home care intervention for at-risk hospitalized elders reduced readmissions , lengthened the time between discharge and readmission , and decreased the costs of providing health care . Thus , the intervention demonstrated great potential in promoting positive outcomes for hospitalized elders at high risk for rehospitalization while reducing costs CONTEXT The worldwide epidemic of diabetes mellitus is increasing the burden of cardiovascular disease , the leading cause of death among persons with diabetes . The independent effect of diabetes on mortality following acute coronary syndromes ( ACS ) is uncertain . OBJECTIVE To evaluate the influence of diabetes on mortality following ACS using a large data base spanning the full spectrum of ACS . DESIGN , SETTING , AND PATIENTS A subgroup analysis of patients with diabetes enrolled in r and omized clinical trials that evaluated ACS therapies .  Patients with ACS in 11 independent Thrombolysis in Myocardial Infa rct ion ( TIMI ) Study Group clinical trials from 1997 to 2006 were pooled , including 62,036 patients ( 46,577 with ST-segment elevation myocardial infa rct ion [ STEMI ] and 15,459 with unstable angina/non-STEMI [ UA/NSTEMI ] ) , of whom 10 613 ( 17.1 % ) had diabetes . A multivariable model was constructed to adjust for baseline characteristics , aspects of ACS presentation , and treatments for the ACS event . MAIN OUTCOME MEASURES Mortality at 30 days and 1 year following ACS among patients with diabetes vs patients without diabetes . RESULTS Mortality at 30 days was significantly higher among patients with diabetes than without diabetes presenting with UA/NSTEMI ( 2.1 % vs 1.1 % , P < .001 ) and STEMI ( 8.5 % vs 5.4 % , P < .001 ) . After adjusting for baseline characteristics and features and management of the ACS event , diabetes was independently associated with higher 30-day mortality after UA/NSTEMI ( odds ratio [ OR ] , 1.78 ; 95 % confidence interval [ CI ] , 1.24 - 2.56 ) or STEMI ( OR , 1.40 ; 95 % CI , 1.24 - 1.57 ) . Diabetes at presentation with ACS was associated with significantly higher mortality 1 year after UA/NSTEMI ( hazard ratio [ HR ] , 1.65 ; 95 % CI , 1.30 - 2.10 ) or STEMI ( HR , 1.22 ; 95 % CI , 1.08 - 1.38 ) . By 1 year following ACS , patients with diabetes presenting with UA/NSTEMI had a risk of death that approached patients without diabetes presenting with STEMI ( 7.2 % vs 8.1 % ) . CONCLUSION Despite modern therapies for ACS , diabetes confers a significant adverse prognosis , which highlights the importance of aggressive strategies to manage this high-risk population with unstable ischemic heart disease BACKGROUND Recent clinical trials have shown that modification of plasma lipoprotein concentrations can favorably alter progression of coronary atherosclerosis , but no data exist on the effects of a comprehensive program of risk reduction involving both changes in lifestyle and medications . This study tested the hypothesis that intensive multiple risk factor reduction over 4 years would significantly reduce the rate of progression of atherosclerosis in the coronary arteries of men and women compared with subjects r and omly assigned to the usual care of their physician .  METHODS AND RESULTS Three hundred men ( n = 259 ) and women ( n = 41 ) ( mean age , 56 + /- 7.4 years ) with angiographically defined coronary atherosclerosis were r and omly assigned to usual care ( n = 155 ) or multifactor risk reduction ( n = 145 ) . Patients assigned to risk reduction were provided individualized programs involving a low-fat and -cholesterol diet , exercise , weight loss , smoking cessation , and medications to favorably alter lipoprotein profiles . Computer-assisted quantitative coronary arteriography was performed at baseline and after 4 years . The main angiographic outcome was the rate of change in the minimal diameter of diseased segments . All subjects underwent medical and risk factor evaluations at baseline and yearly for 4 years , and reasons for all hospitalizations and deaths were documented . Of the 300 subjects r and omized , 274 ( 91.3 % ) completed a follow-up arteriogram , and 246 ( 82 % ) had comparative measurements of segments with visible disease at baseline and follow-up . Intensive risk reduction result ed in highly significant improvements in various risk factors , including low-density lipoprotein cholesterol and apolipoprotein B ( both , 22 % ) , high-density lipoprotein cholesterol ( + 12 % ) , plasma triglycerides ( -20 % ) , body weight ( -4 % ) , exercise capacity ( + 20 % ) , and intake of dietary fat ( -24 % ) and cholesterol ( -40 % ) compared with relatively small changes in the usual-care group . No change was observed in lipoprotein(a ) in either group . The risk-reduction group showed a rate of narrowing of diseased coronary artery segments that was 47 % less than that for subjects in the usual-care group ( change in minimal diameter , -0.024 + /- 0.066 mm/y versus -0.045 + /- 0.073 mm/y ; P < .02 , two-tailed ) . Three deaths occurred in each group . There were 25 hospitalizations in the risk-reduction group initiated by clinical cardiac events compared with 44 in the usual-care group ( rate ratio , 0.61 ; P = .05 ; 95 % confidence interval , 0.4 to 0.9 ) . CONCLUSIONS Intensive multifactor risk reduction conducted over 4 years favorably altered the rate of luminal narrowing in coronary arteries of men and women with coronary artery disease and decreased hospitalizations for clinical cardiac events Medication compliance may be a problem in the management of patients with diabetes . Some physicians initially treat patients having non-insulin-dependent diabetes with oral sulfonylureas because they fear greater compliance problems with insulin therapy . We compared compliance with insulin and chlorpropamide in patients newly beginning medication for NIDDM . Seventy-seven adults with hyperglycemia despite diet therapy were r and omly assigned to chlorpropamide or insulin . Compliance was measured four times over 24 wk . Patients then crossed over to the other medication and were followed for 24 additional weeks . Overall , there were no differences in compliance with the two medications in terms of percent of prescription used , proportion taking at least 80 % of prescribed medication , self-report of medication or diet compliance , or protocol dropout rates . However , treatment satisfaction was higher with chlorpropamide , and most patients preferred chlorpropamide to insulin ( P < 0.0001 ) . While such differences in satisfaction may affect long-term compliance , physicians should not assume that their patients will be less compliant with insulin than with oral sulfonylureas Evidence suggests that diet and exercise are associated with improved glucose tolerance for patients with non-insulin-dependent diabetes mellitus ( NIDDM ) . Seventy-six volunteer adult patients with NIDDM were each assigned to one of four programs : 1 ) diet , 2 ) exercise , 3 ) diet plus exercise , or 4 ) education ( control ) . Each program required ten weekly meetings . Detailed evaluations were completed prior to the program and after three , six , 12 , and 18 months . Evaluations included various psychosocial measures , measures of the quality of life , and fasting blood glucose , glycosylated hemoglobin , and relative weight determinations . Of the 76 original participants , 70 completed the 18-month follow-up study . At 18 months , the combination diet- and -exercise group had achieved the greatest reductions in glycosylated hemoglobin measures . In addition , this group showed significant improvements on a general quality of life measure . These improvements were largely uncorrelated with changes in weight . The authors conclude that the combination of dietary change and physical conditioning benefits NIDDM patients , and that the benefits may be independent of substantial weight loss BACKGROUND There are limited data describing the presenting characteristics , management , and outcomes of diabetic and nondiabetic patients with an acute coronary syndrome ( ACS ) . OBJECTIVE To examine differences in these factors , patients with ST-segment elevation acute myocardial infa rct ion , non-ST-segment elevation acute myocardial infa rct ion , and unstable angina were enrolled in a large multinational coronary disease registry . METHODS The Global Registry of Acute Coronary Events is a prospect i ve observational study of patients hospitalized with an ACS at 94 hospitals in 14 countries . The study sample consisted of 5403 patients with ST-segment elevation acute myocardial infa rct ion , 4725 with non-ST-segment elevation acute myocardial infa rct ion , and 5988 with unstable angina . RESULTS Approximately 1 in 4 patients presented to participating hospitals with a history of diabetes . Patients with diabetes were older , more often women , with a greater prevalence of comorbidities , and they were less likely to be treated with effective cardiac therapies than nondiabetic patients . Patients with diabetes who developed an ACS were at increased risk for each hospital outcome examined including heart failure , renal failure , cardiogenic shock , and death . These differences remained after adjustment for potentially confounding prognostic factors . CONCLUSIONS A considerable proportion of patients with an ACS has diabetes and is at increased risk for adverse outcomes compared with patients without diabetes . There are certain proven therapeutic strategies that remain underused in the diabetic population . A more widespread awareness of this increased risk and a more diligent use of proven cardiac treatment approaches are indicated for patients with diabetes who develop an ACS Abstract Objective : To evaluate the effects of secondary prevention clinics run by nurses in general practice on the health of patients with coronary heart disease . Design : R and omised controlled trial of clinics over one year with assessment by self completed postal question naires and audit of medical records at the start and end of the trial . Setting : R and om sample of 19 general practice s in northeast Scotl and . Subjects : 1173 patients ( 685 men and 488 women ) under 80 years with working diagnoses of coronary heart disease who did not have terminal illness or dementia and were not housebound . Intervention : Clinic staff promoted medical and lifestyle aspects of secondary prevention and offered regular follow up . Main outcome measures : Health status measured by the SF-36 question naire , chest pain by the angina type specification , and anxiety and depression by the hospital anxiety and depression scale . Use of health services before and during the study . Results : There were significant improvements in six of eight health status domains ( all functioning scales , pain , and general health ) among patients attending the clinic . Role limitations attributed to physical problems improved most ( adjusted difference 8.52 , 95 % confidence interval 4.16 to 12.9 ) . Fe
