Cardiovascular single-unit stay: a case study in change.
(65/291)
A cardiovascular single-unit-stay program began at North Memorial Medical Center, Robbinsdale, Minn, in January 2000. Before then, cardiac surgery patients had been admitted to the intensive care unit directly from the operating room and then transferred to the postcoronary care unit on postoperative day 1 or 2. The traditional care delivery model created multiple transfers and delays in care, which often led to dissatisfaction among patients, increased costs, and greater potential for errors. The cardiovascular single-unit-stay program allows patients to stay in the same room with a consistent care team throughout the patients' postoperative course. Decreased lengths of stay, decreased morbidity and mortality, increased satisfaction among patients and their families, and improved collaboration between members of the multidisciplinary team are just a few of the positive trends since the program's inception.

Lived experience of critically ill patients' family members during cardiopulmonary resuscitation.
(66/291)
BACKGROUND: During resuscitative efforts, patients' family members are often barred from the patients' rooms and may never have the opportunity to see their loved ones alive again. Recently, the need to ask family members to leave the room is being questioned. Little is known about families' perceptions of cardiopulmonary resuscitation. OBJECTIVE: To describe the experiences, thoughts, and perceptions of family members of critically ill patients during cardiopulmonary resuscitation in the intensive care unit. METHOD: Six family members whose loved ones underwent cardiopulmonary resuscitation and survived consented to an audiotaped interview. During the interview, family members were asked to describe their experiences during the resuscitation. Interviews were transcribed and were analyzed for relevant themes by using Van Manen thematic analysis. RESULTS: One major theme emerged. Should we go or should we stay? Additionally, 2 subthemes emerged: What is going on? and You do your job. A model, the family's experience with cardiopulmonary resuscitation, was developed to reflect the research findings. CONCLUSIONS: During the period of resuscitation, healthcare professionals neglect to recognize that patients' family members are experiencing crisis along with the patients and that coping mechanisms are impaired. Moreover, the family members' informational and proximity needs are often ignored during this time of crisis. Addressing these needs through appropriate nursing interventions will become increasingly important as patients' family members begin to remain with their loved ones during cardiopulmonary resuscitation.

Increased prescription of thrombolytic treatment to elderly patients with suspected acute myocardial infarction associated with audit.
(67/291)
OBJECTIVES: To assess prescription of thrombolytic treatment to elderly patients with suspected acute myocardial infarction and the incidence of side effects. DESIGN: Retrospective analysis of prescriptions during five months (first audit) followed by prospective analysis of uptake of treatment during five months after interventions in clinical management; prospective assessment of adverse events during thrombolytic treatment. SETTING: Coronary care unit of large district general hospital. PATIENTS: 110 patients aged greater than or equal to 65 with subsequently proved acute myocardial infarction admitted in first audit and 119 admitted in the second. MAIN OUTCOME MEASURES: Site of infarct, prescription of thrombolysis treatment, reasons for nonprescription, complications. RESULTS: Before intervention thrombolytic treatment was prescribed to 13/110 (12%) patients with subsequently confirmed myocardial infarction and after intervention to 55/119 (46%) patients (p less than 0.01). In the first audit no patients with angina received thrombolytic treatment whereas 13/79 (16%) were treated in the second audit. Increased prescription of thrombolytic treatment in the second audit was associated with significantly fewer exclusions owing to dyspepsia (p less than 0.05) and unstated or unsatisfactory reasons (p less than 0.01) Streptokinase infusions were completed uneventfully in 75% (48/64) and 77% (10/13) of patients with infarction and angina respectively. Side effects of treatment were more common in patients with inferior than with anterior infarcts (16/42 (30%) v 3/24 (13%), p less than 0.05). CONCLUSIONS: Low rates of prescription of thrombolytic treatment to elderly patients with suspected acute myocardial infarction were identified and corrected. Streptokinase treatment was associated with transient arrhythmias or hypotension in about a third of these patients with infarcts, particularly those with electrocardiographic changes in inferior leads.

Emergency department thrombolysis improves door to needle times.
(68/291)
OBJECTIVE: To identify the effect on door to needle (DTN) time of moving the site of thrombolysis delivery from the coronary care unit (CCU) to the emergency department (ED). To ascertain if moving the site of thrombolysis enables appropriate use of thrombolysis. DESIGN: Prospective cohort study. SETTING: CCU and ED of a 450 bed Scottish district general hospital without on-site primary angioplasty. PARTICIPANTS: Primary site for thrombolysis of patients presenting to the hospital with ST elevation MI (STEMI) moved from CCU to ED on 1 April 2000. Study patients who had a confirmed STEMI and/or received thrombolytic therapy before this date were defined as the pre-change group; those who were diagnosed as STEMI and/or received thrombolytic therapy after this date were defined as the post-change group. STATISTICAL ANALYSIS: Mann-Whitney test was used to compare medians and chi(2) test for categorical data. RESULTS: 1349 patients were discharged from CCU with a diagnosis of STEMI or received thrombolysis in the ED or CCU between April 1998 and April 2002. There were 632 patients in the pre-change group and 654 patients in the post-change group. Sixty three patients were excluded. Median DTN time for the pre-change group (321 thrombolysed patients) was 64 minutes and median DTN time for the post-change group (324 thrombolysed patients) was 35 minutes, a median difference of 25 minutes (95% CI for difference 20 to 29 minutes, p<0.0001, Mann-Whitney U test). A total of 37 patients were thrombolysed but did not have a final diagnosis of STEMI. CONCLUSION: A significant reduction in DTN times accompanied this change in practice in this hospital. (+info)
Management of myocardial infarction: implications for current policy derived from the Nottingham Heart Attack Register.
(69/291)
OBJECTIVE: A register of patients with heart attacks in the Nottingham Health District has been maintained since 1973. Data from 1982 to 1984 inclusive, a period before trials of thrombolytic therapy started in Nottingham, were analysed to provide background information for the introduction of a policy of routine thrombolysis for appropriate patients. DESIGN: Data were collected prospectively on all patients transported to hospital in the Nottingham Health District with suspected myocardial infarction in the years 1982-84 and on patients treated at home during that time. SETTING: Two district general hospitals responsible for all emergency admissions in the health district. PATIENTS: 6712 patients admitted to hospital with suspected myocardial infarction and 1887 patients found dead on arrival at hospital. Approximately 1500 patients in whom a myocardial infarction was suspected were treated at home, but only 125 were identified who had a definite or probable infarction. RESULTS: Among the patients admitted within 24 hours of the onset of symptoms, the median delay from onset to hospital admission was 174 minutes; 25% of patients were admitted within 91 minutes. The only factor that seemed to affect the time taken was the patient's decision to call a general practitioner or an emergency ambulance. If a general practitioner referred the patient to hospital the median delay was 247 minutes, compared with 100 minutes when the patient summoned an ambulance. Ninety three per cent of all patients were transported by ambulance. The median time from the call for the ambulance to hospital arrival was 29 minutes. Once a patient was admitted to hospital, the time to admission and general practitioner involvement seemed relatively unimportant as predictors of outcome. Patients admitted more than nine hours after onset of symptoms with a diagnosis of definite or probable infarction had a poorer outcome than those admitted earlier (in-hospital mortality 22.4% v 13.1%). The fatality rates of those admitted to a coronary care unit or to an ordinary medical ward are similar. CONCLUSION: Although the introduction of thrombolytic therapy has brought with it an increased awareness of the need to minimise any delay in time to admission, it seems that in a predominantly urban area like Nottingham, patients with a suspected heart attack will continue to be admitted to hospital most quickly if an ambulance crew rather than a general practitioner is called. Because the ambulance crew was in contact with such patients for only a short time it seems unlikely that administration of a thrombolytic drug in the ambulance would be helpful. (+info)
Differences in access to coronary care unit among patients with acute myocardial infarction in Rome: old, ill, and poor people hold the burden of inefficiency.
(70/291)
BACKGROUND: Direct admission to Coronary Care Unit (CCU) on hospital arrival can be considered as a good proxy for adequate management in patients with acute myocardial infarction (AMI), as it has been associated with better prognosis. We analyzed a cohort of patients with AMI hospitalized in Rome (Italy) in 1997-2000 to assess the proportion directly admitted to CCU and to investigate the effect of patient characteristics such as gender, age, illness severity on admission, and socio-economic status (SES) on CCU admission practices. METHODS: Using discharge data, we analyzed a cohort of 9127 AMI patients. Illness severity on admission was determined using the Deyo's adaptation of the Charlson's comorbidity index, and each patient was assigned to one to four SES groups (level I referring to the highest SES) defined by a socioeconomic index, derived by the characteristics of the census tract of residence. The effect of gender, age, illness severity and SES, on risk of non-admission to CCU was investigated using a logistic regression model (OR, CI 95%). RESULTS: Only 53.9% of patients were directly admitted to CCU, and access to optimal care was more frequently offered to younger patients (OR = 0.35; 95%CI = 0.25-0.48 when comparing 85+ to >=50 years), those with less severe illness (OR = 0.48; 95%CI = 0.37-0.61 when comparing Charlson index 3+ to 0) and the socially advantaged (OR = 0.81; 95%CI = 0.66-0.99 when comparing low to high SES). CONCLUSION: In Rome, Italy, standard optimal coronary care is underprovided. It seems to be granted preferentially to the better off, even after controversial clinical criteria, such as age and severity of illness, are taken into account. (+info)
Thrombolytic therapy for myocardial infarction facilitated by mobile coronary care.
(71/291)
BACKGROUND: The benefit of Thrombolytic Therapy (TT) for acute myocardial infarction is time sensitive. In Northern Ireland widespread availability of mobile coronary care units facilitates delivery of TT to heart attack victims. This region-wide prospective observational study assessed the efficacy of various methods of delivery of TT. METHODS: All 15 acute hospitals providing acute coronary care in Northern Ireland participated and data were collected prospectively over six months on all patients admitted with acute myocardial infarction or who received TT. The information was analysed regarding appropriateness of TT, methods and timeliness of delivery of TT and mortality rates. Performance was measured against National Service Framework standards. FINDINGS: Of 1638 patients with acute myocardial infarction 584 were considered eligible for TT and 494 (85 %) received it, in addition to 18 patients without infarction. Of the 512 thrombolysed patients 282 (55%) were treated in hospital coronary care units, 131 (26%) were treated pre-hospital, 97 (19%) in accident and emergency departments, and two in general medical wards. Overall median call-to-needle time was 87 (7-1110) mins and this was shortest for pre-hospital treatment when 55% of call-to-needle times were < or = 60 mins. For patients treated in hospital median door-to-needle time was 46 (0-1065) mins and this was shortest when TT was administered by accident and emergency staff, when 65% of door-to-needle times were < or = 30 mins. In patients with ST elevation myocardial infarction TT was associated with lower mortality, especially when administered pre-hospital. INTERPRETATION: NSF targets for TT are unlikely to be met in Northern Ireland without increasing pre-hospital delivery of TT and by improving collaboration between coronary care and accident and emergency staff with TT availability in accident and emergency departments.

Real-time perfusion adenosine stress echocardiography in the coronary care unit: a feasible bedside tool for predicting coronary artery stenosis in patients with acute coronary syndrome.
(72/291)
Myocardial contrast echocardiography using power modulation real-time perfusion (RTP) is an appealing method for bedside risk stratification of patients with acute coronary syndrome. In this study, we aimed to evaluate the accuracy in predicting significant coronary stenosis of a bedside RTP adenosine stress protocol in patients with acute coronary syndrome. METHODS: Prior to coronary angiography, 36 consecutive in-patients with acute coronary syndrome underwent a bedside adenosine stress echocardiography with RTP in the coronary care unit. Visual assessment of both perfusion and wall motion was made, comparing rest and hyperaemia images. Each segment was attributed to one of the three main coronary vessel areas. RESULTS: The sensitivity of predicting significant stenosis was 87, 83 and 81% for left anterior descending, circumflex and right posterior descending areas, respectively. Specificity was 69, 67 and 60%, respectively. The positive predictive values were 83, 79 and 74%, respectively. CONCLUSIONS: RTP using adenosine is a feasible bedside tool in predicting the area of significant coronary stenosis and could be helpful as a bedside decision-making tool in the clinical setting. More studies are required to assess the clinical value of RTP adenosine stress echocardiography. (+info)
