The effectiveness of a "critical pathway" in the management of laryngectomy patients.

BACKGROUND: This is a retrospective review of medical and financial records to test the hypothesis that the use of a critical pathway specifically designed for the management of laryngectomy patients will result in improved patient care, decreased length of hospitalization, and optimal allocation of resources. METHODS: Thirty patients undergoing laryngectomy before the implementation of the laryngectomy critical pathway were compared with 30 patients after implementation of the pathway. Clinical outcomes, length of hospitalization, and cost analyses were performed. RESULTS: Adjusting for two outliers, the average length of stay for pathway patients was 7.3 days vs 12 days for prepathway patients. A total estimated cost-savings of $204,000 was ultimately achieved. CONCLUSIONS: Our laryngectomy critical pathway has resulted in improved patient care and optimized allocation of medical resources.

Critical pathway for administering high-dose chemotherapy followed by peripheral blood stem cell rescue in the outpatient setting.

PURPOSE/OBJECTIVES: To explain the rationale and process of outpatient critical pathway development for sequential high-dose chemotherapy followed by peripheral blood stem cell transplantation. DATA SOURCES: Published books and journal articles. DATA SYNTHESIS: Complex treatment for patients with metastatic breast cancer is shifting to the outpatient area. To make this therapy safe and cost effective, a process for monitoring this type of outpatient care needs to be developed. CONCLUSIONS: Collaboration with a multidisciplinary team is important in ensuring quality of care for complex outpatient treatment protocols. Critical pathway development can serve as a road map for delivering this care. IMPLICATIONS FOR NURSING PRACTICE: As team leaders, nurses should oversee the critical pathway development and implementation. Nurses also should maintain their role of patient advocacy through monitoring pathway compliance.

Iron chelation with deferoxamine: comparing the results of a critical pathway to a national survey.

PURPOSE: The clinical outcomes of an institution's critical pathway that uses a comprehensive approach to serum ferritin management are reported. The results of this center are compared with the results of a national survey of deferoxamine (DFO) use and serum ferritin level outcomes. METHODS: Current DFO dosing and serum ferritin levels of 38 patients at this center were summarized. A questionnaire was then sent to 98 centers throughout the United States requesting information on criteria for beginning treatment with DFO, administration methods, dose modifications, and serum ferritin levels. RESULTS: The application of a critical pathway in this program resulted in 29 of 38 patients maintaining serum ferritin levels <2,000 ng/mL. Of the 42 institutions that responded to the survey, 10 attained this ferritin level in > or =50% of their patients. Ferritin levels ranged from 500 ng/mL to >20,000 ng/mL, and wide variations were reported in all study parameters. CONCLUSIONS: Iron overload can be effectively managed with alteration of DFO doses and routes using a consistent approach. Modification of administration methods, including administration of DFO during red blood cell transfusions, are indicated to attain ferritin levels of <2,000 ng/mL.

The effect of developing patient compendiums for critical pathways on patient satisfaction.

We examined the impact of developing a patient compendium to a critical pathway on patient satisfaction scores. It was our hypothesis that by sharing the contents of a critical pathway, by using a patient compendium, we would improve patient satisfaction by establishing realistic patient expectations for patients undergoing cardiac bypass graft surgery. A satisfaction survey was sent to patients before the hospital began to use the patient compendium to the pathway and to another group of patients after initiation of a compendium. Although there were some trends suggesting an improvement in patient satisfaction scores, there was no statistical difference in satisfaction before or after the compendium was in use.

Comparison between critical pathway guidelines and management of deep-vein thrombosis: retrospective cohort study.

AIM: To compare the key steps of standard deep-vein thrombosis management with the critical pathway practice guidelines, and to assess the outcome of the treatment after 6 months. METHOD: This retrospective cohort study (from January 1, 1997 to December 31, 1998) included 172 patients with uncomplicated deep-vein thrombosis of lower extremities, consecutively admitted via emergency room. The data were collected from the entry register in emergency room and medical charts. The outcome of therapy was assessed 6 months after the acute event. RESULTS: A bolus dose of heparin was administered to 81 (46%) patients. The recommended initial heparin infusion rate at 1250 U/h was employed in only 26 (15%) patients. Time to activated partial thromboplastin time >60 s was met in 29 (17%) patients. All patients but one received heparin therapy longer than 96 h. The recommended time to a therapeutic international normalized ratio of less than 120 h was achieved in 134 (78%) patients, but the average length of a stay in the hospital exceeded the recommended 5. 5 days by 86%. Six months later, compressive ultrasonography revealed 44 (28.9%) cases of complete vein obstruction, 67 (44.1%) cases of partial recanalization and 41 (27%) cases with a normal finding. Recurrent thrombosis developed in 16 patients (10.5%) and acute pulmonary embolism in 4 (2.6%) patients. CONCLUSION: Our results considerably differ from the critical pathway guidelines due to the lower initial heparin doses and longer diagnostic assessment of thrombosis etiology. Our approach to deep-vein thrombosis treatment was a combination of the critical pathway guidelines and the conventional regimen. The clinical outcome in our series did not differ significantly from the outcome after the conventional way of treatment.

A critical pathway for intimate partner violence across the continuum of care.

OBJECTIVE: The authors developed an interdisciplinary critical pathway for intimate partner violence (IPV) assessment and intervention for use across health care settings. Intimate partner violence may be emotional, physical, and/or sexual and involves coercion and control by one partner over the other. DESIGN: A pathway developed with input from focus groups of battered women was subjected to a modified Delphi technique to improve the pathway's scientific accuracy and feasibility. SETTING: The study was conducted in one urban, one suburban, and one rural hospital with IPV advocacy programs in the mid-Atlantic region of the United States. PATIENTS/PARTICIPANTS: Four researchers and 13 clinicians participated in the validation, with at least one physician, one nurse, and one social worker or IPV counselor from each hospital. MAIN OUTCOME MEASURES: Each element of the pathway was analyzed for the degree of consensus on scientific accuracy and feasibility. RESULTS: Consensus on the scientific accuracy and feasibility of the pathway was achieved after three rounds of the Delphi process. CONCLUSIONS: This is the first known critical pathway for IPV. It addresses physical and mental health and safety and has content validity affirmed by an interdisciplinary panel of experts. Further process and outcome evaluation is warranted and invited.

Protocols and critical pathways for stroke care.

We have presented a conceptual approach toward developing clinical protocols and critical pathways in a complex multidisciplinary environment with a commitment to clinical excellence, evidence-based practice methodology, and education. The process and the mood surrounding these have been more important in our view than any particular protocol or pathway. They have generated an attitude aiming toward avoidance of complications rather than crisis management. They have contributed to a philosophy of integrative multidisciplinary collaborations among various specialists, house staff, and nursing and paramedical personnel and a greater mutual sensitivity in interactions with medical center management and administration. The overall impact of this global approach has been quantifiable (Fig. 6), although the role(s) of one or more facets of it cannot be independently defined (21, 22). Protocols and clinical pathways should be viewed as components of total quality management. They should not be allowed to restrict the patient's or physician's choice of interventions, they should not inhibit in any way innovation or the introduction of novel methodologies. Yet, protocols and critical pathways should and do generate a pressure on every member of the health-care team, a sense of negative entropy constantly urging a move toward a higher level of excellence and quality.

Case management, critical pathways, and myocardial infarction.

Case management is an innovative way to simultaneously modify healthcare delivery, uphold standards of care, and reduce healthcare costs. The case manager oversees the patient's condition, progress, and consumption of resources. Information is constantly analyzed and used to regulate treatment plans in accordance with the critical pathways. The goal of this regulation is to produce outcomes that serve the patient and the healthcare system. The complexity of individualized patient care can require an unlimited number of pathways if all variances are considered. If all variances are not considered, then the quality of care is hindered, rehospitalization occurs, and the goals of the critical pathways are not achieved. Therefore, effective use of case management and critical pathways involves flexible guidelines, maintains focus on outcomes, enhances efficiency, increases cost-effectiveness, and retains a high quality of patient care.

Impact of a critical pathway on acute myocardial infarction quality indicators.

STUDY OBJECTIVE: To determine the impact of a critical pathway on acute myocardial infarction (AMI) quality indicators. DESIGN: Retrospective chart review. SETTING: Large university hospital. PATIENTS: One hundred seventy-five patients who underwent primary percutaneous transluminal angioplasty for AMI (control group 89 patients, intervention group 86 patients). MEASUREMENTS AND MAIN RESULTS: The medical records of the control group (1998-1999) were reviewed for door-to-balloon (DtB) time (the time between the patient's arrival at the emergency department and the first balloon inflation during a percutaneous transluminal coronary angioplasty procedure). Drug therapy prescribed at hospital discharge (aspirin, beta-blocker, angiotensin-converting enzyme [ACE] inhibitor, and lipid-lowering therapy) was also reviewed. The data collected for the control group were compared with the intervention group data (2000-2001). The impact of the pathway was evaluated using the Wilcoxon rank sum test, odds ratios (ORs), and chi2 tests. The DtB time was significantly lower in the intervention group versus the control group (91.5 vs 108 min, p < 0.01), and fewer intervention patients exceeded the guidelines with a DtB time longer than 120 minutes (OR 0.38, p < 0.01). In addition, the intervention group was more likely than the control group to be prescribed an ACE inhibitor (OR 3.7, p < 0.01) or lipid-lowering therapy (OR 3.7, p = 0.02) at discharge. Aspirin and beta-blockers were not prescribed differently in the intervention versus control groups (aspirin 95.2% vs 96.2%, beta-blockers 93.5% vs 92.6%). CONCLUSION: These data suggest that in the current era of published treatment guidelines, implementation of a critical pathway can further improve AMI quality indicators and clinical care.

Managing critical pathway variances.

As the use of critical pathways expands at an increasing rate, we are faced with the issue of how to manage variances from the pathway. Variance management is not clearly defined in the literature, and many institutions search for the best approach. We have implemented a number of different techniques for variance management at Fletcher Allen Health Care. Our success benefits both patients and providers.

Variation in the management of deep vein thrombosis: implications for the potential impact of a critical pathway.

PURPOSE: To evaluate the potential impact of a practice guideline in the form of a critical pathway on variation and quality of care in patients with deep vein thrombosis (DVT). METHODS: Goals were identified for key steps and processes that were believed to be important for meeting a length-of-stay (LOS) goal of 5.5 days, and for improving quality of care for patients with DVT. Data collected via chart review were used to determine the percentage o patients with uncomplicated DVT admitted in the year after October 1, 1992, whose management would have met these goals. RESULTS: Only 11 (12%) of 92 eligible patients with a primary discharge diagnosis of DVT met the LOS goal. In 30%, the activated partial thromboplastin time (aPTT) was >60 seconds within a target of 12 hours after admission. The goals for the initiation of warfarin (within 12 hours after aPTT >60 seconds) and the achievement of a therapeutic international normalized ratio (INR) level (within 120 hours) were met in 51% and 58% of patients, respectively. The target duration of intravenous heparin therapy was achieved in 78% of patients. Only 18% of patients, however, were discharged within 12 hours after 96 hours of heparin therapy had been given and a therapeutic INR had been achieved. CONCLUSIONS: These data demonstrate considerable variation in management of uncomplicated DVT at a single hospital, suggesting that a critical pathway could have impact on both LOS and quality of care.

Outcomes assessment of total hip and total knee arthroplasty: critical pathways, variance analysis, and continuous quality improvement.

Using critical pathways, with variance analysis and continuous quality improvement techniques to refine the pathways, the efficiency of total hip and total knee surgeries in one academic health center was maximized. Using a retrospective cohort study design, complications, readmissions, morbidity/mortality, and function scores were examined in two groups of patients attended by the same surgeon for the year before and the year after the implementation of an outcomes management program. The length of stay was reduced by 57% for knee patients and by 46% for hip patients. Hospital costs were reduced 11% for all knees and 38% for hips. Complications were also significantly reduced. There was no statistically significant difference between pre- or postoperative knee or hip outcome scores. The program resulted in significant savings without adversely affecting overall outcome.

Algorithms, critical pathways, and computer software for wound care: contemporary status and future potential.

The contemporary use of algorithms, critical pathways, and computer software significantly affects all aspects of healthcare treatment from primary care to acute trauma management. Guidelines and heuristic devices specific to chronic wound care have been introduced to assist with quality implementation and monitoring of outcomes in a cost-conscious American healthcare system. Some wound care algorithms and critical pathways even have been computerized. This article discusses the differences among the various forms of wound care heuristic methods, describes their advantages and disadvantages, and suggests how they can be successfully implemented in clinical practice settings. Directions for future research also are offered.

Making the transition to critical pathways--a community behavioral health center's approach.

BACKGROUND: Shawnee Hills, Inc., formally began the transition to critical pathways in January 1996. The goal was to design and implement a service delivery model with clearly defined clinical paths and appropriate and functional technical support systems. No specific goal date for full implementation was designated; however, the intent was to move into the new system in a manner that allowed both consumer and employee participation in the planning process and to accommodate the organization's transition from a fee-for-service to a capitated model of contracting for services. The target date for completion of phase one, research and initial planning, was March 1, 1996. Although there were a number of benefits anticipated in adopting the critical paths method (CPM), the primary rationale was threefold: (1) standardizing the quality of care and treatment, (2) cost containment, and (3) better positioning of the organization for success within a capitated funding environment. A review of the publications indicated that the CPM had proved to be effective in other healthcare fields. In addition, the goals and approaches inherent within the CPM were consistent with the organization's total quality management (TQM) philosophy and operational practices. METHOD: By using the approach common to the organization since the adoption of the principles and practices of TQM in early 1992, a team was appointed with the mission of reengineering the clinical services delivery model. Unlike previous instances, however, this team was comprised largely of senior leadership, and two staff members were assigned on a full-time basis. A more detailed review of publications was conducted and, where possible, identification of critical pathways developed within the mental health field in other states were secured. Focus groups were used to address "best" or "preferred" practices for specific populations and age groups. Team members provided an orientation to the process, along with the opportunity to critique proposed pathways and models for service delivery as they were drafted to all employees through participation in ongoing staff development efforts. The center leadership was kept informed and was provided additional opportunities for input through regular presentations to the Quality Council that meets on a weekly basis. RESULTS: The first phase of the transition, research and initial planning, was completed on March 1, 1996. To date, the team has adopted or developed initial drafts of proposed clinical pathways for frequently occurring diagnoses within adult and child mental health, adult and child substance abuse, and specific to early childhood for the mental retarded or developmentally delayed. A model for clinical pathways was developed incorporating the JCAHO requirements to address assessment, care, and education at the major junctures of service delivery. In addition, the team formulated recommendations specific to priority areas for each major pathway and the approach to be taken in the transition from a fee-for-service to a capitated environment. A service delivery model built around acute care and continuing care was outlined, but remains a work-in-progress at this time. Finalizing the model and the completion of the clinical pathways for specific diagnostic groupings are two priorities for the second phase, product development-continued planning and transition, now underway. CONCLUSIONS: Although the effort is very much outcomes-oriented, data are not available at this early stage in the process. (ABSTRACT TRUNCATED)

Treatment algorithms and critical pathways for acute coronary syndromes.

Although numerous clinical trials have identified many advances in the treatment of patients with acute coronary syndromes (ACS), registries of clinical practice have identified that in clinical practice a large proportion of patients do not receive guideline-recommended therapies. In addition to development and dissemination of national guidelines, there is a need for specific tools to ensure that the guideline recommendations are implemented on a patient-by-patient basis. Better adherence to practice guidelines has been found to be associated with improved outcomes. Critical pathways and/or the process of Continuous Quality Improvement (CQI) are means of trying to improve care. Critical pathways are standardized protocols that aim to optimize and streamline patient care, which usually involve standardized order sets, (or computerized ones), and/or simple pocket cards, reminders, or checklists of the appropriate therapies. Another key part of an overall CQI effort is to monitor data on performance-i.e. utilization of guideline recommended therapies. Several well-conducted studies, showing that particular use of critical pathways, can lead to improve quality of care.

Empyema: development of a critical pathway.

Over the past 20 years at the authors' institution, the management of empyema has evolved. The authors recently have developed a critical pathway in an effort to facilitate diagnosis, guide therapy, and reduce cost. Currently, the average length of stay using this pathway is 4 to 5 days with decreased cost compared to the historic length of stay and a national children's hospital database. The authors review steps to develop a critical pathway as well as discuss their pathway for empyema management.

Evaluation of a human immunodeficiency virus rule out tuberculosis critical pathway as an intervention to decrease nosocomial transmission of tuberculosis in the inpatient setting.

Nosocomial transmission of Mycobacterium tuberculosis (TB) is a recognized risk in health care settings, and is a particular concern in settings where human immunodeficiency virus (HIV)-infected persons receive care. TB control guidelines have been effective in prevention of nosocomial TB outbreaks and protection of patients and health care workers. In 1993 a South Florida academic medical center noted an increase in TB cases, particularly in HIV-infected persons who had been inpatients. A multidisciplinary team developed an HIV Rule Out TB Critical Pathway as an intervention to deter nosocomial transmission of TB. The pathway was implemented in 1995 on the Special Immunology/Infectious Disease (SI/ID) inpatient unit. This paper describes an evaluation study conducted to determine the effectiveness of the pathway as an intervention to deter nosocomial TB in relation to two areas: (1) early identification of HIV-infected patients with potential TB, followed by immediate placement in respiratory isolation and (2) protection of SI/ID unit personnel from occupational TB exposure. A retrospective review was conducted in June 1999 on the medical records of all patients who had been placed on the HIV Rule Out TB Critical Pathway from 1995-1998. A review was also done of the medical center's confirmed TB cases, and employee health records for tuberculin skin testing (TST) of employees during this time period. The review demonstrated that all HIV-infected patients with confirmed TB had been identified, placed on the pathway and admitted to respiratory isolation at the onset of hospital admission, deterring the potential for a nosocomial TB outbreak. However, in 1998 two SI/ID staff converted from a nonreactive to a reactive TST. Although the pathway was only partially successful in TB protection for staff members, other factors may have caused the TST conversions. A study recommendation is that institutions develop an HIV Rule Out TB Critical Pathway, along with a Rule Out TB Pathway for patients who are not HIV-infected but present with symptoms that may be indicative of TB infection.

Critical pathway for the emergency department management of acute asthma: effect on resource utilization.

STUDY OBJECTIVE: To determine the effect of a critical pathway on resource utilization in asthmatic patients. METHODS: The study combined a prospective analysis of 149 patients with asthma treated by a pathway protocol with a retrospective analysis of 97 patients with asthma treated by conventional means. The setting was a community hospital. RESULTS: Among patients treated by protocol, oxygen use declined by 19% (P = .001), handheld nebulizer treatments by 33% (P = .001), saline locks by 15% (P = .011), and intravenous steroid administration by 13% (P = .034). There was an increase in the use of metered-dose inhalers with spacer by 64% (P = .001) and oral steroids by 18% (P = .027). CONCLUSION: A critical pathway, based primarily on national guidelines, can be an effective means of treating asthma patients in terms of resource utilization.
