Modifiable risk factors associated with deep sternal site infection after coronary artery bypass grafting.

OBJECTIVE: Our objective was to identify risk factors for deep sternal site infection after coronary artery bypass grafting at a community hospital. METHODS: We compared the prevalence of deep sternal site infection among patients having coronary artery bypass grafting during the study (January 1995-March 1998) and pre-study (January 1992-December 1994) periods. We compared any patient having a deep sternal site infection after coronary artery bypass graft surgery during the study period (case-patients) with randomly selected patients who had coronary artery bypass graft surgery but no deep sternal site infection during the same period (control-patients). RESULTS: Deep sternal site infections were significantly more common during the study than during the pre-study period (30/1796 [1.7%] vs 9/1232 [0.7%]; P =.04). Among 30 case-patients, 29 (97%) returned to the operating room for sternal debridement or rewiring, and 2 (7%) died. In multivariable analyses, cefuroxime receipt 2 hours or more before incision (odds ratio = 5.0), diabetes mellitus with a preoperative blood glucose level of 200 mg/dL or more (odds ratio = 10.2), and staple use for skin closure (odds ratio = 4.0) were independent risk factors for deep sternal site infection. Staple use was a risk factor only for patients with a normal body mass index. CONCLUSIONS: Appropriate timing of antimicrobial prophylaxis, control of preoperative blood glucose levels, and avoidance of staple use in patients with a normal body mass index should prevent deep sternal site infection after coronary artery bypass graft operations.

Risk factors for radial artery harvest site infection following coronary artery bypass graft surgery.

Radial arteries increasingly are used during coronary artery bypass graft (CABG) surgery. Although risk factors for saphenous vein harvest site infection (HSI) have been reported, rates of and risk factors for radial artery HSI are not well established. We compared rates of radial artery HSI that were detected by 2 surveillance methods, regular and heightened. Risk factors were determined by a case-control study. We identified 35 radial artery HSIs ("case sites") in 26 case patients. The radial artery HSI rate was significantly higher during heightened surveillance than during routine surveillance (12.3% vs. 3.1%, respectively; P=.002). Multivariate analysis showed that diabetes mellitus with a preoperative glucose level >/=200 mg/dL (odds ratio [OR], 4.4; P=. 01) and duration of surgery >/=5 h (OR, 3.1; P=.02) were independent risk factors for radial artery HSI. Infection is a common complication of radial artery harvesting for CABG surgery, and infection rates are dependent on the intensity of surveillance. We identified preoperative hyperglycemia and surgery duration as independent risk factors for radial artery HSI.

Refining the measurement of physician job satisfaction: results from the Physician Worklife Survey. SGIM Career Satisfaction Study Group. Society of General Internal Medicine.

BACKGROUND: Physician job satisfaction has been linked to various patient care and health system outcomes. A survey instrument that concisely measures physicians' satisfaction with various job facets can help diverse stake-holders to better understand and manage these outcomes. OBJECTIVE: To document the development and validation of a multidimensional physician job satisfaction measure and separate global satisfaction measures. DESIGN: Self-administered questionnaire: Physician Worklife Survey (PWS). SUBJECTS: A pilot study employed a national American Medical Association Masterfile sample of US primary care physicians and random samples from four states. Responses (n = 835; 55% return rate) were randomly assigned to developmental (n = 560) or cross-validation (n = 275) samples. A national sample (n = 2,325; 52% response rate) of physicians was used in a subsequent validation study. RESULTS: A 38-item, 10-facet satisfaction measure resulting from factor and reliability analyses of 70 pilot items was further reduced to 36 items. Reliabilities of the 10 facets ranged from .65 to .77. Three scales measuring global job, career, and specialty satisfaction were also constructed with reliabilities from .84 to .88. Results supported face, content, convergent, and discriminant validity of the measures. CONCLUSIONS: Physician job satisfaction is a complex phenomenon that can be measured using the PWS.

Measuring physician job satisfaction in a changing workplace and a challenging environment. SGIM Career Satisfaction Study Group. Society of General Internal Medicine.

BACKGROUND: Changes in the demographic, specialty, and employment sector composition of medicine have altered physicians' jobs, limiting autonomy and reducing morale. Because physician job satisfaction has been linked to clinical variables, better measurement might help to ameliorate conditions linked to medical disaffection, possibly improving health care. OBJECTIVE: To document conceptual development, item construction, and use of content experts in designing multidimensional measures of physician job satisfaction and global satisfaction scales for assessing physicians' job perceptions across settings and specialties. DESIGN: Using previous research, physician focus groups, secondary analysis of survey data, interviews with physician informants, and a multispecialty physician expert panel, distinct job facets and statements representing those facets were developed. RESULTS: Facets from previously validated instruments included autonomy, relationships with colleagues, relationships with patients, relationships with staff, pay, resources, and status. New facets included intrinsic satisfaction, free time away from work, administrative support, and community involvement. Physician status items were reconfigured into relationships with peers, patients, staff, and community, yielding 10 hypothetical facets. Global scales and items were developed representing satisfaction with job, career, and specialty. CONCLUSIONS: A comprehensive approach to assessing physician job satisfaction yielded 10 facets, some of which had not been previously identified, and generated a matching pool of items for subsequent use in field tests.

Requirements for infrastructure and essential activities of infection control and epidemiology in hospitals: A consensus panel report. Society for Healthcare Epidemiology of America.

The scientific basis for claims of efficacy of nosocomial infection surveillance and control programs was established by the Study on the Efficacy of Nosocomial Infection Control project. Subsequent analyses have demonstrated nosocomial infection prevention and control programs to be not only clinically effective but also cost-effective. Although governmental and professional organizations have developed a wide variety of useful recommendations and guidelines for infection control, and apart from general guidance provided by the Joint Commission on Accreditation of Healthcare Organizations, there are surprisingly few recommendations on infrastructure and essential activities for infection control and epidemiology programs. In April 1996, the Society for Healthcare Epidemiology of America established a consensus panel to develop recommendations for optimal infrastructure and essential activities of infection control and epidemiology programs in hospitals. The following report represents the consensus panel's best assessment of needs for a healthy and effective hospital-based infection control and epidemiology program. The recommendations fall into eight categories: managing critical data and information; setting and recommending policies and procedures; compliance with regulations, guidelines, and accreditation requirements; employee health; direct intervention to prevent transmission of infectious diseases; education and training of healthcare workers; personnel resources; and nonpersonnel resources. The consensus panel used an evidence-based approach and categorized recommendations according to modifications of the scheme developed by the Clinical Affairs Committee of the Infectious Diseases Society of America and the Centers for Disease Control and Prevention's Hospital Infection Control Practices Advisory Committee.

Recommended practices for surveillance. Association for Professionals in Infection Control and Epidemiology, Inc. Surveillance Initiative working Group.

Demonstration of quality health care includes documentation of outcomes of care. Surveillance is a comprehensive method of measuring outcomes and related processes of care, analyzing the data, and providing information to members of the health care team to assist in improving those outcomes. Surveillance is an essential component of effective clinical programs designed to reduce the frequency of adverse events such as infection or injury. Although there is no single or "right" method of surveillance design or implementation, sound epidemiologic principles must form the foundation of effective systems and must be understood by key participants in the surveillance program and supported by senior management. Teamwork and collaboration across the health care spectrum are important for the development of surveillance plans. Each health care organization must tailor its surveillance systems to maximize resources by focusing on population characteristics, outcome priorities, and organizational objectives. To ensure quality of surveillance, the following elements must be incorporated: A written plan should serve as the foundation of any surveillance program. The plan should outline important objectives and elements of the surveillance process so that resources can be targeted appropriately. Thoroughness or intensity of surveillance for an area of interest must be maintained at the same level over time. Fluctuations of a surveillance rate have no meaning unless the same level of data collection is maintained. External rate comparisons are meaningless unless the systems used have comparable intensity. All the elements of surveillance should be used with consistency over time. This includes application of surveillance definitions and rate calculation methods. Personnel resources need to be appropriate for the type of surveillance being performed. This includes trained professionals who understand epidemiology and who have access to continuing professional education opportunities. Other resources essential to surveillance include computer support, information and technology services, clerical services, and administrative understanding and support to maintain a quality program. As a means of quality control and to ensure accuracy, the data and process of surveillance should undergo periodic evaluation and validation. This document is intended to assist professionals who plan and conduct surveillance programs as well as those who assure that there is appropriate organizational support to accomplish appropriate surveillance. While design of surveillance systems must be unique for each organization, incorporation of these seven core Recommended Practices for Surveillance provides a scientific framework to approach surveillance programs.

Changing nature of physician satisfaction with health maintenance organization and fee-for-service practices.

BACKGROUND: Managed care practice arrangements, or health maintenance organizations (HMOs), are sufficiently mature to examine whether physicians' level of satisfaction has changed as managed care has developed. This study compares Dane County, Wisconsin, physicians' satisfaction with HMO and fee-for-service (FFS) practices in 1986 with that of 1993 and examines factors that contribute to satisfaction in an HMO-dominated environment. METHODS: Cross-sectional surveys were mailed to all Dane County physicians in active practice in 1986 and 1993. Physician overall support for HMO development and satisfaction with work situation was measured with single items. Overall satisfaction and clinical freedom within HMO and FFS practices were measured using statistically reliable scales. RESULTS: Significantly more physicians were supportive of the development of HMOs in 1993 than in 1986, and more than two thirds of physicians in 1993 were satisfied in their current work situation. Primary care physicians were significantly more satisfied than subspecialists across most dimensions of satisfaction. Perceived clinical freedom and satisfaction with income continued to be major predictors of satisfaction in 1993 as in 1986. While physicians' satisfaction with HMO practice remained stable, their satisfaction with FFS practice was significantly lower in 1993 than in 1986. Satisfaction with Medicare practice, which was not measured in 1986, was significantly less than with HMO or FFS practice in 1993. CONCLUSIONS: Analyses suggest that primary care physicians are more satisfied than subspecialists with their HMO practice because of their greater satisfaction with HMO-generated income and the expanded clinical freedom they have in HMO practice. An across-the-board decline in satisfaction with FFS practice may be attributable to diminishing clinical freedom resulting from indemnity carriers' increasing micromanagement of patient care.

Physician satisfaction with the development of HMOs in Dane County: 1983-1993.

In September 1993, the 1,196 active physicians in Dane County were surveyed to learn their satisfaction with the development of HMOs and comparisons to similar satisfaction surveys in 1986 and 1983. Among the 675 usable responses, 65% reported that they were satisfied or very satisfied with their current work, which is about the same as the 1986 survey when 68% reported that they were satisfied. Other findings suggest support for HMO development in Dane County. Moreover, 66% reported support for the basic principles of the Clinton health system reform plan announced in September 1993.

Physician satisfaction in a managed care environment.

BACKGROUND: The professional literature suggests that changes toward the bureaucratization of medical practice have led to increasing job dissatisfaction, especially in primary care. To investigate this claim, we surveyed physicians in Dane County, Wisconsin, who practice in a bureaucratic setting. Dane County has experienced essentially a demise in independent practice, ie, most physicians practice in organizational settings where expenses and total patient income are pooled. About 85% of physicians have joined one of the six competing health maintenance organizations (HMOs). METHODS: In 1986 all 850 physicians in Dane County were surveyed to determine their perceptions of clinical freedom, satisfaction with income, status in their profession, autonomy, resources, and professional relations, and their overall satisfaction. RESULTS: We found that over 69% of primary care physicians were very satisfied or satisfied with their practices overall compared with 68% of physicians in all specialties. Differences between family practice and other primary care specialties were not statistically significant. Our regression analysis showed that only for satisfaction with income were responses from primary care physicians significantly different from those of physicians in surgical specialties. Perceptions of clinical autonomy and specific organizational settings were more important to predicting satisfaction. Also, age and sex contributed to differences in satisfaction with resources and status, respectively. CONCLUSIONS: We conclude that satisfaction can be fairly high for primary care physicians in bureaucratic settings similar to that of Dane County.

Temporal trends in septicemia in a community hospital.

A prior study of septicemia in our community teaching hospital demonstrated the importance of case mix categories in understanding differences in rates of septicemia seen in hospitals. This study provides a 10 year, in 1982, and a 15 year, in 1987, follow-up of septicemia from the same hospital. A substantial increase in the incidence of septicemia was noted in 1982 and 1987. Underlying illness categories continued to be important predictors of incidence of septicemia and fatality rates. The sites of infections, relative mix of community-acquired and nosocomial infections, and mix of organisms were fairly stable throughout the period. The overall incidence of septicemia increased from 34/10,000 admissions in 1970-1973 to 87/10,000 in 1982 and 103/10,000 in 1987. The major explanations for these increases are: (a) a striking increase in the use of blood cultures from 1 blood culture per 10.4 patients in 1973 to 1 blood culture per 3.3 patients in 1987; (b) an increase in the proportion of patients in the Medicare age group from 13% in 1970-1973 to 24% in 1987, with that age group accounting for 33% of the cases of septicemia in 1970-1973 and 55% in 1982 and 1987; and (c) a modest change in the case mix category of ultimately fatal underlying illness and a probable increase in the acuity of illness for most patients admitted. Parallel changes in frequency of use of blood cultures have occurred at the previously evaluated medical school teaching hospital in the same community. These same explanations are likely to be applicable for the same time period in other acute care hospitals as well.
