Critical pathways in the emergency department.
The actual development of the CP is an easy undertaking that an experienced emergency nurse can accomplish. The important points to remember are as follows: (1) include all disciplines that provide patient care in the development of the CP, (2) use realistic time frames (i.e., those currently found to be true in the emergency department, not those that are perceived to be ideal), (3) thoroughly educate the staff about the value of the CP in the emergency department, and, finally, (4) make sure that staff members know how to document variances. CPs in the emergency department give physicians and nurses common ground on which to negotiate patient care management more efficiently and effectively. They are a logical way to bring case management into the acute care setting. With the cost of ED visits continually rising, patient acuity levels increasing, and resources declining, expedient, coordinated, multidisciplinary action is crucial in giving total quality care to each patient.
Physician-Directed Diagnostic and Therapeutic Plans: a quality cure for America's health-care crisis.
The most effective way to improve quality is to reduce variation in the processes of providing a service. Physician-Directed Diagnostic and Therapeutic (PDDT) Plans are a proven methodology for reducing variation in clinical processes and improving the quality of care. A major part of the PDDT Plan process is the development of a critical pathway. Critical pathways are an application of Total Quality Management (TQM) principles to clinical care which have provided clear, tangible results in those hospitals committed to this process. These pathways define the processes, timelines and responsibilities associated with the patient's clinical needs from preadmission to post discharge. Representatives of the various health-care professions involved in treating the specified patient populations work together, led by a physician, to define the processes of care. When completed, everyone involved in treating the patient understands what is to be done, by whom, and when. The pathways allow clinicians to plan ahead and let the patient and family know what to expect. Through establishing standards of care, these critical pathways also reduce the uncertainty of treatment decisions and free physicians from having to practice defensive medicine, and thus reduce cost. While the most visible outcome of this process is the actual PDDT Plan, it is not necessarily the most important. The very process of designing the pathway improves intra- and interdisciplinary communication, and fosters teamwork.
Standardization of perioperative management: clinical pathways.
Many initiatives have been introduced in the past decades to standardize and improve clinical perioperative care and thereby improve patient care. Clinical pathways (also known as integrated care pathways, critical pathways, critical paths, care paths) are structured multidisciplinary care plans that detail essential steps in the care of patients with a specific clinical problem. They are designed to support the implementation and translation of national guidelines into local protocols and their subsequent application to clinical practice. In surgery, clinical pathways are standardized protocols for the management of patients who have common conditions undergoing common surgical procedures.
Critical care pathways in thromboembolic disease.
Critical Care Pathways are outlines of each day's expected interventions and treatments for a particular process. They are part of a larger concept of case management, as an extramural, multidisciplinary approach to a patient's problems, with details suitable to their personality and case. This constitutes the overall concept of managed care. Rather than DVT, this presentation focuses on thromboembolism. I think you'll see why I chose to emphasize this complication instead. Modern medicine has been turned upside down; the rules are different, expectations are different. I would suggest to physicians who are resisting the CCP concept that it may be your salvation as much as it is a paperwork torment. It's clearly a way to provide better care for your patients.
Critical care pathway development: the way forward.
In many NHS trusts throughout the UK, critical pathways are being used as a method of managing patient care, enabling trusts to ensure that patients receive appropriate, high quality, cost-effective care. At the same time they can meet some of the requirements of The Patient's Charter, such as involving patients in decision making and keeping them informed during periods of treatment. This article first describes critical pathways and then discusses briefly the reasons why pathways were developed at the Guy's and St Thomas' Trust, and the stages of development before their introduction.
The Ras radiation resistance pathway.
The critical pathways determining the resistance of tumor cells to ionizing radiation are poorly defined. Because the ras oncogene, a gene activated in many human cancers treated with radiotherapy, can induce increased radioresistance, we have asked which Ras effector pathways are significant in conferring a survival advantage to tumor cells. The phosphoinositide-3-kinase (PI3K) inhibitor LY294002 radiosensitized cells bearing mutant ras oncogenes, but the survival of cells with wild-type ras was not affected. Inhibition of the PI3K downstream target p70S6K by rapamycin, the Raf-MEK-MAPK pathway with PD98059, or the Ras-MEK kinase-p38 pathway with SB203580 had no effect on radiation survival in cells with oncogenic ras. Expression of active PI3K in cells with wild-type ras resulted in increased radiation resistance that could be inhibited by LY294002. These experiments have indicated the importance of PI3K in mediating enhanced radioresistance and have implicated PI3K as a potential target for specific radiosensitization of tumors.
[Design, implementation, and results of the clinical pathway for herniated lumbar disk].
INTRODUCTION: Clinical or critical pathways are a useful tool in the continuous quality improvement. They develop the main characteristics of the quality programs: implementation of the evidence based medicine, increase staff and patient satisfaction and adequacy in hospital costs. This is the application of evidence-based medicine to a process management and it promotes integration of clinical guides, protocols and algorithms. OBJECTIVE: We present our experience in the design, and first nine month's implementation and development of a clinical pathway for lumbar hemilaminectomy. PATIENTS AND METHODS: This clinical pathway consists on four documents: main guide and check sheet, preprinted treatment orders and variation sheet, iconographic information for the patients and patient satisfaction questionnaire. After desing, development and a pilot study, the hemilaminectomy critical pathway was permanently adopted by our Service. A total of 106 patients underwent programmed lumbar disc hemilaminectomy in our Service between April and December-1999. Patients' average age was 44.7 years (SD = 11.2), 55.3% were men and 43.7% women. Twelve were hospitalized in a ward other than Neurosurgery unit and therefore were excluded from the study. This evaluation is based on the initial results obtained from both the pathway documents and the general data collected as usual during hospital care. The impact of the critical pathway on hospital stay has been assessed by comparing the average stay of critical pathway patients to the average of the 70 hemilaminectomies performed at our Service in the period April-December 1998. RESULTS: Clinical pathway coverage has been 68% (standard > 80%). The patients' average stay was 4 days (SD = 1.1), one day more than planned. The pathway establishes a 4 day hospital stay (3 bed-days), a time that was fulfilled by 49% of the patients. The average stay of the 1998 patients was 5.6 days (SD = 2.7), 1.6 days more than the clinical pathway patients (p < 0.0001). Additionally, undesirable variability in the length of hospital stays was also reduced. Analysis of variations identified those corresponding to patient's condition, increases in medication beyond that originally specified due to patient needs, and unjustified prolonged stays. There were no systematic variations. There was a 2.2% incidence of adverse effects. Although satisfaction questionnaire was only returned by 51% of the patients (instead of > 70%), satisfaction index were 93% (vs 90%). CONCLUSIONS: Critical pathways are still under development and changing continuously. Nevertheless their impact on improving patient care and satisfaction, and resource consumption is already evident, and it constitutes a major aim to work in its complete development.
[Application of the information technology for critical path and neurointensive care unit].
An effectiveness of neurointensive care unit for the treatment of neurological diseases and an application of the information technology (IT) for this and a critical pathway were discussed. A critical pathway is useful to make a standardized treatment, to reduce the days in hospital and to obtain an informed consent. But the hospital information system should include the critical pathway in itself otherwise doctors have to make duplicated order to nurses and the hospital ordering system.
Critical radionuclide/critical pathway analysis for the U.S. Department of Energy's Savannah River Site.
Many different radionuclides have been released to the environment from the Savannah River Site (SRS) during the facility's operational history. However, as shown by this analysis, only a small number of the released radionuclides have been significant contributors to potential doses and risks to off-site people. This article documents the radiological critical contaminant/critical pathway analysis performed for SRS. If site missions and operations remain constant over the next 30 years, only tritium oxide releases are projected to exceed a maximally exposed individual (MEI) risk of 1.0E-06 for either the airborne or liquid pathways. The critical exposure pathways associated with site airborne releases are inhalation and vegetation consumption, whereas the critical exposure pathways associated with liquid releases are drinking water and fish consumption. For the SRS-specific, nontypical exposure pathways (i.e., recreational fishing and deer and hog hunting), cesium-137 is the critical radionuclide.
The effect of a perioperative clinical pathway for knee replacement surgery on hospital costs.
UNLABELLED: Clinical pathways are being introduced by hospitals to reduce costs and control unnecessary variation in care. We studied 766 inpatients to measure the impact of a perioperative clinical pathway for patients undergoing knee replacement surgery on hospital costs. One hundred twenty patients underwent knee replacement surgery before the development of a perioperative clinical pathway, and 63 patients underwent knee replacement surgery after pathway implementation. As control groups, we contemporaneously studied 332 patients undergoing radical prostatectomy (no clinical pathway in place for these patients) and 251 patients undergoing hip replacement surgery without a clinical pathway (no clinical pathway and same surgeons as patients having knee replacement surgery). Total hospitalization costs (not charges), excluding professional fees, were computed for all patients. Mean (+/-SD) hospital costs for knee replacement surgery decreased from $21,709 +/- $5985 to $17,618 +/- $3152 after implementation of the clinical pathway. The percent decrease in hospitalization costs was 1.56-fold greater (95% confidence interval 1.02-2.28) in the knee replacement patients than in the radical prostatectomy patients and 2.02-fold greater (95% confidence interval 1.13-5.22) than in the hip replacement patients. If patient outcomes (e.g., patient satisfaction) remain constant with clinical pathways, clinical pathways may be a useful tool for incremental improvements in the cost of perioperative care. IMPLICATIONS: Doctors and nurses can proactively organize and record the elements of hospital care results in a clinical pathway, also known as "care pathways" or "critical pathways." We found that implementing a clinical pathway for patients undergoing knee replacement surgery reduced the hospitalization costs of this surgery.
Economic assessment of the community-acquired pneumonia intervention trial employing levofloxacin.
OBJECTIVE: The purpose of this study was to assess use of a critical pathway designed to manage community-acquired pneumonia more efficiently than its management with conventional therapy. METHODS: Economic outcomes were assessed in conjunction with a cluster-design, randomized, controlled trial. Nineteen participating Canadian hospitals were randomized to implement the critical pathway (n = 9) or conventional therapy (n = 10). The critical pathway included a clinical prediction rule to guide the admission decision, treatment with levofloxacin, and practice guidelines. Patient data on medical resource use, lost productivity, and quality of life were collected prospectively for > or =6 weeks after treatment. Costs were calculated from the government, health care system, and societal perspectives, with imputation of missing outpatient costs and the costs of lost productivity when necessary. Bootstrapping was used to identify 95% CIs for the total cost per patient. RESULTS: The analysis included all eligible patients in the critical pathway (n = 716) and conventional therapy (n = 1027) arms. There were fewer hospital admissions in the critical pathway arm than in the conventional therapy arm, both overall (46.5% vs 62.2%; P = 0.01) and in low-risk patients (33.2% vs 46.8%; P < 0.001). Compared with conventional therapy, hospitals in the critical pathway arm had 1.6 fewer bed days per patient managed (P = 0.05) and used fewer inpatient medical resources. The 2 study arms had similar outpatient, readmission, and lost-productivity costs, and similar quality-of-life outcomes. The critical pathway produced cost savings from all 3 perspectives that ranged from $457 to $994 per patient. CONCLUSIONS: The critical pathway employing levofloxacin resulted in cost savings compared with conventional therapy and did not compromise health outcomes.
The Ras-mitogen-activated protein kinase pathway is critical for the activation of matrix metalloproteinase secretion and the invasiveness in v-crk-transformed 3Y1.
To search for the intracellular signaling pathway critical for the secretion of matrix metalloproteinases (MMP), we studied the effects of dominant negative Ras (S17N Ras) and dominant negative MEK1 (MEK1AA) expression in v-crk-transformed 3Y1. Expression of either S17N Ras or MEK1AA dramatically suppressed the augmented secretion of MMP-2 and MMP-9 in v-crk-transfected 3Y1. Similarly, a Ras farnesyltransferase inhibitor, manumycin A, and a MEK1 inhibitor, U0126, suppressed MMP secretion in a dose-dependent manner, whereas a PI3 kinase inhibitor, wortmannin, could not. In addition, the suppression of MMP secretion by S17N Ras showed good correlation with the inhibition of in vitro invasiveness of the cells. In contrast, expression of dominant negative C3G did not suppress MMP secretion, although it substantially blocked the c-Jun N-terminal kinase activation. Taken together, the Ras-MEK1 pathway, but not the C3G-JNK pathway, seems to play a key role in the activation of MMP secretion and, hence, the invasiveness of v-crk-transformed cells.
Bedside chest radiography as part of a postcardiac surgery critical care pathway: a means of decreasing utilization without adverse clinical impact.
OBJECTIVE: To evaluate the use of bedside chest radiography and patient outcome before and after implementation of a cardiac surgery critical care pathway that included guidelines for bedside radiography. DESIGN: A cohort observational study. SETTING: A university hospital in the midwest. PATIENTS: Three groups, of 100 patients each, undergoing cardiac surgery in 1990, 1991, and 1995. INTERVENTION: Introduction of a critical care pathway. MEASUREMENTS: Medical records were retrospectively reviewed in three groups of 100 patients each: before the introduction of the critical care pathway; 2 months after introduction of the pathway in 1991; and 4 yrs after introduction in 1995. Data were analyzed to determine operative risk for each group. Subsequent analyses determined bedside radiography use, total length of hospital stay, and patient outcome (mortality rate, complications requiring intervention, and reoperation) during hospitalization and at outpatient follow-up 15-30 days postdischarge. RESULTS: Total length of hospital stay was shorter for the 1995 group (7.6+/-6.6 days) compared with other groups (prepathway, 11.1+/-10.3 days; 1991 postpathway, 10.2+/-9.6 days; p<.05). The mean numbers of radiographs per patient were as follows: prepathway, 5.1; 1991 postpathway, 5.2; and 1995 postpathway, 3.3. The mean number of radiographs in the 1995 group was significantly lower (p = .02). More patients had the proposed number of two bedside radiographs described in the pathway in the 1995 group compared with the other groups (prepathway, p<.0001; the two-month postpathway group, p = .01). Twenty-three malpositioned catheters/tubes were found in the prepathway and 1991 groups compared with 11 in the 1995 group (p = .02). No statistically significant difference was found in inpatient complications (mediastinal bleeding, pneumothoraces, and pleural effusions), postdischarge complications, reoperations, or mortality rate. CONCLUSION: Introduction of a critical care pathway can decrease the use of bedside radiography without adversely affecting near-term patient outcomes.
Collection of process data after cardiac surgery: initial implementation with a Java-based intranet applet.
BACKGROUND: Using a Java-based intranet program (applet), we collected postoperative process data after coronary artery bypass grafting. METHODS: A Java-based applet was developed and deployed on a hospital intranet. Briefly, the nurse entered patient process data using a point and click interface. The applet generated a nursing note, and process data were saved in a Microsoft Access database. In 10 patients, this method was validated by comparison with a retrospective chart review. In 45 consecutive patients, weekly control charts were generated from the data. When aberrations from the pathway occurred, feedback was initiated to restore the goals of the critical pathway. RESULTS: The intranet process data collection method was verified by a manual chart review with 98% sensitivity. The control charts for time to extubation, intensive care unit stay, and hospital stay showed a deviation from critical pathway goals after the first 20 patients. Feedback modulation was associated with a return to critical pathway goals. CONCLUSIONS: Java-based applets are inexpensive and can collect accurate postoperative process data, identify critical pathway deviations, and allow timely feedback of process data.
Adherence to guidelines for community-acquired pneumonia: does it decrease cost of care?
Community-acquired pneumonia (CAP) is a common diagnosis and care of CAP is responsible for significant healthcare expenditures, the majority of which are for patients who require hospitalisation. Studies have shown that significant variation exists among institutions with respect to antibacterial costs and length of stay (LOS) for CAP. These variations do not appear to be associated with significant differences in patient outcomes. This information has stimulated the development of practice guidelines and critical pathways to optimise the care of patients with CAP. The central focus of guidelines is recommendations for antibacterial therapy; critical pathways include recommendations for therapy, but focus on the process of care for patients with CAP. Guidelines and critical pathways are time consuming to develop and their implementation requires significant institutional resources. Therefore, it is essential that they are shown to be effective, and there has been significant interest in determining if guidelines and pathways can improve the cost effectiveness of care. In the past several years, a number of studies have evaluated the impact of treatment consistent with guidelines on outcomes for patients with CAP. These studies have shown that antibacterial therapy that is consistent with guidelines can reduce LOS, decrease costs, and several have shown a favourable impact on mortality. The majority of these studies have been retrospective reviews. One multicenter prospective, randomised trial of a critical pathway for CAP revealed significant reductions in the hospital admission of patients, LOS and cost of care. Other studies of processes of care have been mainly 'before and after' interventions; many have shown reductions in LOS and costs. Based on the available data, it is reasonable to expect that adherence to guidelines and critical pathways can reduce the cost of care for CAP; however, randomised controlled trials that include a formal cost-effectiveness analysis are needed. Even if the data to support the use of guidelines and pathways are robust, those who develop and implement them need to anticipate and understand barriers to physician adherence.
Trauma 24-hour observation critical path.
BACKGROUND: The 24-hour observation critical pathway for trauma is a clinical tool developed to expedite health care delivery to minimally injured patients. The use of patient care, BS, guidelines and physician-approved standing orders was implemented in a Level I trauma center. METHODS: A retrospective chart review was performed of 122 patients admitted via the emergency department between December 1, 1993, and May 31, 1994. All patients were evaluated in the emergency department by emergency medicine and trauma physicians and deemed appropriate for 24-hour observation. The information collected included patient demographics, hospital charges, injuries, length of stay, diagnostic tests, consultations, and variances from the critical pathway. RESULTS: During the 6-month study period, there were 600 trauma admissions. Of those admissions, 122 patients (20%) were evaluated in the emergency department and deemed appropriate for enrollment in the 24-hour observation pathway. The charts of these patients were reviewed. Fourteen admissions were determined inappropriate for the critical pathway because of the severity of injuries or discharge against medical advice. One hundred eight charts were evaluated further. Eighty-nine patients (80%) completed the critical pathway with a length of stay of 24 hours. CONCLUSION: The 24-hour observation critical pathway was designed and used appropriately as exemplified by an overall 80% completion rate. The critical pathway offers a mechanism to streamline care of the minimally injured trauma patient. It also serves as a quality-improvement tool for increasing efficiency, decreasing utilization of resources, and decreasing length of stay.
