Postoperative complications among octogenarians after cardiovascular surgery.

BACKGROUND: The octogenarian patient is often perceived as too fragile to undergo cardiothoracic surgery. Our study aimed to compare postoperative complications in patients aged less than 80 versus elderly patients (80 years or more) after surgical cardiac intervention (coronary artery bypass or valve replacement). METHODS: Subjects were all patients (n = 8,361) who had an open-heart procedure, either coronary artery bypass or valve implantation or replacement, at two medical centers located in northern Virginia using the same surgical group. A computerized medical record database was reviewed to determine preoperative risk factors and postoperative outcomes. Predictors of complications were identified by univariate and multivariate logistic regression. RESULTS: A total of 3,214 complications were recorded. The most prevalent complications were prolonged ventilation time in the intensive care unit, reoperation for bleeding, and pneumonia. The overall mortality rate was 2.4% (204 of 8,361). Persons aged over 80 years had nearly double the mortality rate compared with younger patients (4.1% [18 of 444] to 2.3% [186 of 7,917]). Age greater than 80 years (odds ratio = 2.65, 95% confidence interval = 2.18 to 3.22) and male gender (odds ratio = 0.62, 95% confidence interval = 0.56 to 0.69) were the best univariate predictors of a single postoperative complication. CONCLUSIONS: Octogenarian patients manifested twice the risk of death from a cardiac intervention with an average 2-day longer hospital stay compared with their younger counterparts. Furthermore, octogenarians were at markedly higher risk of nonfatal postoperative complications.

Functional status improvement in the elderly following coronary artery bypass graft.

This study assessed functional status changes among elderly persons (aged 65+) during the first 2 years following an elective coronary artery bypass graft. Physical functional status increased 39.1% from baseline to 1 year and 2.1% from 1 to 2 years. Role functioning increased 42.7% at 1 year and slightly decreased by 2.1% from 1 to 2 years postsurgery. From baseline to 1 year, female patients nearly doubled the percent gain of men for both Physical Function (.3% vs +33.9%, respectively) and Role Function (+62.0% vs +37.8%, respectively). Physical Function scores continued to increase from 1 to 2 years for women (+9.5%) compared to men (+0.7%). These findings suggest that elderly persons can expect postsurgical functional status to increase steadily during the first 2 years after surgery.

Preoperative state of mind among patients undergoing CABG: effect on length of stay and postoperative complications.

This study was undertaken to determine if a pessimistic self-assessment prior to an elective coronary artery bypass graft (CABG) was predictive of postoperative complications and increased length of stay (LOS). Subjects (n = 565), aged 65 and older and undergoing elective CABG, were stratified into 2 groups (optimistic, pessimistic) based on their mental health subscale scores prior to surgery. After adjusting for age, gender, and severity of disease, the average LOS for pessimistic patients was 1.3 days longer than for optimistic patients. Despite adjustment for previous CABG, renal failure, peripheral vascular disease, and gender, pessimism was associated with an increased risk of prolonged ventilation time and permanent stroke. Negative state of mind prior to a major cardiovascular intervention may be predictive of increased LOS, permanent stroke, and prolonged ventilation time.

Gender differences for Rapid After Bypass Back Into Telemetry tract following cardiac surgery.

The Rapid After Bypass Back Into Telemetry program is based on a simple clinical algorithm to predict same-day transfer of patients to the cardiac telemetry unit following cardiac surgery. This program proved to be an excellent predictor for decreased postoperative complications, shorter intensive care unit and hospital stay, and lower costs. We believe that any candidate for cardiac surgery should be screened for eligibility to participate in the program with special focus on female patients to further improve their outcomes.

Guided imagery in cardiac surgery.

Clinical research has demonstrated that guided imagery, a simple form of relaxation, can reduce preoperative anxiety and postoperative pain among patients undergoing surgical procedures. In 1998, the cardiac surgery team implemented a guided imagery program to compare cardiac surgical outcomes between two groups of patients: with and without guided imagery. Data from the hospital financial cost/accounting database and patient satisfaction data were collected and matched to the two groups of patients. A questionnaire was developed to assess the benefits of the guided imagery program to those who elected to participate in it. Patients who completed the guided imagery program had a shorter average length of stay, a decrease in average direct pharmacy costs, and a decrease in average direct pain medication costs while maintaining high overall patient satisfaction with the care and treatment provided. Guided imagery is now considered a complementary means to reduce anxiety, pain, and length of stay among our cardiac surgery patients.

Incidence of postoperative complications among coronary artery bypass patients with and without hypertension.

Patients (n = 3301) undergoing first-time elective coronary artery bypass surgery, between 1994 and 2000, with or without hypertension were compared for the incidence of postoperative complications. Fifty-five leg infections were documented (overall incidence 1.7%). Hypertension patients had a significantly increased risk of leg infections (2.45% versus 0.46%). A 10-year increase in age was associated with a 44% increased risk of leg infections (odds ratio = 1.44; 95% confidence interval = 1.09, 1.91). Hypertension patients also had a greater risk of stroke and prolonged ventilation time but not of postoperative mortality.

Cardiac surgery outcomes.

Accrediting organizations and payers are demanding valid and reliable data that demonstrate the value of services. Federal agencies, healthcare industry groups, and healthcare watchdog groups are increasing the demand for public access to outcomes data. A new and growing outcomes dynamic is the information requested by prospective patients in an increasingly consumer-oriented business. Patients demand outcomes, and resources are developing to meet these demands. Physicians are increasingly confronted with requests for information about their mortality and morbidity rates, malpractice suits, and disciplinary actions received. For example, in Virginia, prospective patients have access to data provided by the nonprofit group Virginia Health Information. After numerous resolutions by the Virginia Senate since 1999, the prospective Virginia medical consumer now has access to several annual publications: Virginia Hospitals: A Consumer's Guide, 1999 Annual Report and Strategic Plan Update, and the 1999 Industry Report: Virginia Hospitals and Nursing Facilities. Consumers have access to cardiac outcomes data stratified by hospital, gender, and cardiac service line (cardiac surgery, noninvasive cardiology, and invasive cardiology). This is particularly relevant to IHI because Virginia Health Information specifically targets cardiac care. IHI has a sizable investment in cardiovascular outcomes and has found outcomes measurement and research are key to providing quality care. IHI's goal is to move from an outcomes management model to a disease management model. The hope is to incorporate all aspects of the patient's continuum of care, from preoperative and diagnostic services through cardiac interventions to postoperative rehabilitation. Furthermore, every step along the way will be supported with functional status and quality of life assessments. Although these goals are ambitious and expensive, the return on investment is high.

National databases and clinical practice specialist: decreasing postoperative atrial fibrillation following cardiac surgery.

In this article, we document how an interdisciplinary committee of health professionals led to an approximate 50% reduction in the incidence of postoperative atrial fibrillation (AF) following a cardiac surgery procedure by using preoperative loading and dosing of PO amiodarone and beta blockade. Patients in this report (n = 3397) included all coronary artery bypass surgery (CABG) and valve replacement/repair procedures from January 1, 2000 to June 30, 2002. The incidence of postoperative AF for a CABG or valve replacement/repair procedure was 19.0% for period A (preprotocol) and 13.5% for period B (postprotocol). This translates into an absolute risk reduction of 5.5% or 113 actual cases of postoperative AF reduced. The role of the clinical practice specialist, a master's prepared nurse, and participation in the national Society of Thoracic Surgeon's database allowed us to track our CABG outcomes, benchmark our outcomes against both national and regional institutions, and make changes in outcomes incidence through performance improvement.
