Application of a prototype process for developing a tube gastrostomy clinical pathway

The development and implementation of clinical pathways as a managed care tool have been widely embraced as principal components of the healthcare industry's drive to reform costly, inconsistent, and often uncontrolled delivery of services. Clinical pathways are not new to healthcare; however, the lack of a defined and systematic process for pathway development has hindered organizational efforts to develop and implement clinical pathways. A multidisciplinary clinical pathway process prototype was identified as a means for effectively defining and linking care and outcomes for patients requiring tube gastrostomy placement at a large military medical facility. This article presents the prototype process for developing a clinical pathway with a practical application to illustrate the process and provides a process template for potential use by others interested in developing multidisciplinary clinical pathways.     

Design, development, and implementation of a critical pathway in simultaneous pancreas-kidney transplant recipients

The purpose of this study was to assess the effect of implementation of a critical pathway after simultaneous pancreas-kidney transplantation on length of stay and hospital charges. Two well-matched groups were compared: 10 patients who received transplants in 1991 (before implementation of the critical pathway) and 10 patients who received transplants in 1995 (after implementation). For the initial transplant hospitalization, the critical pathway was associated with significant reductions in length of stay, total number of laboratory tests, clinical laboratory charges, and total inpatient charges with organ acquisition charges excluded. Despite the rising costs of medical care, we have designed and implemented a critical pathway for simultaneous pancreas-kidney transplantation that has stabilized hospital charges by decreasing length of stay and the number of clinical laboratory tests.     

Design, testing, and results of an outcomes-managed approach to patients requiring prolonged mechanical ventilation

BACKGROUND: Outcomes management that uses critical pathways may decrease costs while improving outcomes for patients who require prolonged mechanical ventilation. OBJECTIVE: To study the efficacy of an outcomes-managed approach to weaning patients from prolonged (more than 3 days) mechanical ventilation. METHODS: A method of multidisciplinary care delivery was designed that included an outcomes manager, a care pathway for patients receiving mechanical ventilation, and weaning protocols. Data collection consisted of three parts: a retrospective review of 124 patients who required prolonged ventilation during a 1-year period before implementation of the care model, a 6-month prospective study in which 91 patients were alternately assigned by month to an outcomes-managed approach or a non-outcomes-managed approach, and a 6-month prospective study of 90 patients in which an outcomes-managed approach without alternate-month assignment was used. RESULTS: Outcomes management had no significant effect on total duration of mechanical ventilation or length of stay in the hospital, days of mechanical ventilation without tracheostomy, days of mechanical ventilation with tracheostomy, or outcome (weaned, withdrawal from mechanical ventilation, death, or transfer without weaning). However, duration of mechanical ventilation was 1.3 days shorter, length of stay in the hospital was 2.1 days shorter, and the cost per case was $ 3341 less for patients in the outcomes-managed group than for patients in the non-outcomes-managed group. CONCLUSION: Outcomes-managed care did not have a significant effect on duration of ventilation, length of stay in the hospital, or outcome in patients receiving long-term mechanical ventilation.     

Impact of a clinical pathway for elective infrarenal aortic reconstructions

OBJECTIVE: To determine the impact of a clinical pathway for elective infrarenal aortic reconstruction on outcome, resource utilization, and cost in a university medical center. SUMMARY BACKGROUND DATA: Clinical pathways have been reported to control costs, reduce resource utilization, and maintain or improve the quality of patient care, although their use during elective aortic reconstructions remains unresolved. METHODS: A clinical pathway was developed for elective infrarenal aortic reconstructions by a multidisciplinary group comprised of representatives from each involved service. The prepathway practice and costs were analyzed and an efficient, cost-effective practice with specific outcome measures was defined. The impact of the pathway was determined by retrospective comparison of outcome, resource utilization, and cost (total and direct variable) between the pathway patients (PATH, n = 45) and a prepathway control group (PRE, n = 20). RESULTS: There were no significant differences in the patient demographics, comorbid conditions, operative indications, or type of reconstruction between the groups. There were no operative deaths and the overall complication rate (PRE, 35% vs. PATH, 34%) was similar. The pathway resulted in significant decreases in the total length of stay and preoperative length of stay and a trend toward a significant decrease (p = 0.08) in the intensive care length of stay for the admission during which the operation was performed. The pathway also resulted in significant decreases in both direct variable and total hospital costs for this admission, as well as a significant decrease in the overall direct variable and total hospital costs for the operative admission and the preoperative evaluation (< or =30 days before operative admission). Despite these reductions, the discharge disposition, 30-day readmissions, and number of postoperative clinic visits within 90 days of discharge were not different. CONCLUSIONS: Implementation of a clinical pathway for elective infrarenal aortic reconstructions dramatically decreased resource utilization and hospital costs without affecting the quality of patient care and did not appear to shift the costs to another setting.     

Does type of colostomy influence outcome of colostomy closure?

A retrospective analysis of 81 patients who had closure of colostomy over a 32-month period was carried out to establish factors affecting the outcome of this operation. Their ages averaged 27 years and there were 69 male patients. The sigmoid colon was the most common site and the loop colostomy was most frequently performed. The majority were closed 3 or more months after construction. Loop colostomy took significantly less time to close and patients were fed significantly earlier compared with the other types. Patients who underwent closure after Hartmann's procedure had the longest hospital stay. The complication rate was 12% and there was no mortality. Colostomy closures in this study had minimal complications and no mortality. The loop colostomy is as easy to close as it is to perform and results in shorter hospital stay.     

Clinical pathway management of total knee arthroplasty

Using a retrospective cohort study design, the authors examined complications, readmissions, morbidity and mortality, and function scores 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 with clinical pathways for patients undergoing total knee arthroplasty at an academic health center. The effectiveness of the pathway constantly was adjusted using variance analysis and continuous quality improvement techniques. This program reduced the length of stay by 57% from a premanagement value of 10.9 +/- 5.4 days in 1994 (Group 1) to 4.7 +/- 1.4 days in 1996 (Group 2). Hospital costs (based on an inflation adjusted cost to charge ratio) for all total knees were reduced 11% from $13,328 +/- $3905 in 1994 to $11,862 +/- $4763 in 1996. Preoperative and postoperative knee scores were 41.1 +/- 16.3 and 84.2 +/- 16.0 for Group 1 and 42.5 +/- 13.0 and 87.0 +/- 10.4 for Group 2, respectively. There was no statistically significant difference between the preoperative or the postoperative knee scores of Groups 1 and 2. The application of clinical pathways, variance analysis, and continuous quality improvement toward the treatment of patients who had total knee arthroplasty at an academic health center resulted in significant savings in length of stay without adversely affecting overall outcome.     

The development and benefits of nursing protocols for fractured neck of femur patients

In this article the authors discuss the development, use and auditing of nursing care protocols, which have been implemented and form a guide for nurses caring for patients with fractured neck of femur in Southend Health Care NHS Trust. The development of these protocols occurred after an initial medical audit, which was followed by a far larger multidisciplinary audit, and both of these revealed there was need for changes in the clinical management of such patients; subsequently a large multidisciplinary working group worked together to develop care protocols/pathways to enable closure of the audit loop. The reasons for focusing on fractured neck of femur as a high priority condition are also discussed. All professional groups caring for these patients were involved in the multidisciplinary working group, which was formed to close the audit loop and to improve clinical practices by increasing the systemization and coordination of care. The development of the nursing protocols represented an extremely important part of this process, and the care of about 700 patients was examined during this work. The audit and associated subsequent work have resulted in direct improvements to both patient care and health outcomes, and the authors conclude that there is great value in developing multidisciplinary protocols, particularly those involving nurses, because they spend more time with patients whilst they are in hospital than any other professional group. The benefits of these nursing protocols have been multifold, in particular they have facilitated a clearer flow of patients through the hospital, increased awareness of responsibilities and reduced duplication of effort, and ensured patients receive the best possible care over the 24-hour period.     

Management of left-sided colonic obstruction by subtotal colectomy and ileocolic anastomosis

OBJECTIVE: To assess complications and functional results of emergency subtotal colectomy with ileocolic anastomosis for acute left-sided colonic obstruction. DESIGN: Retrospective study. SETTING: University hospital, Netherlands. SUBJECTS: 37 patients with acute left-sided colonic obstruction. INTERVENTIONS: Emergency subtotal colectomy with immediate anastomosis (n = 20), Hartmann's procedure (n = 13) or double-loop transverse colostomy (n = 4). MAIN OUTCOME MEASURES: Mortality, morbidity, duration of hospital stay, frequency of defecation, and continence. RESULTS: Morbidity after subtotal colectomy was 10% (n = 2) and mortality 0. There was one anastomotic dehiscence that required a temporary ileostomy. Mean hospital stay was 15 days (range 10-31). All had adequate continence. After 6 weeks mean frequency of defecation was 3/24 hrs (range 2-6). 9 patients died within 2 years of metastatic disease. CONCLUSIONS: Subtotal colectomy with ileocolic anastomosis is a suitable procedure for treating left-sided colonic obstruction provided that pelvic floor function is adequate and a skilled surgeon is available.     

Influence of ejection fraction on hospital mortality, morbidity, and costs for CABG patients

BACKGROUND: Preoperative ejection fraction (EF) has been shown to adversely affect postoperative hospital mortality and morbidity for patients undergoing isolated coronary artery bypass grafting. METHODS: To investigate influence of EF on isolated coronary artery bypass grafting outcomes (overall hospital mortality, hospital cardiac mortality, hospital morbidity, and hospital costs), data were reviewed from 1,354 consecutive patients who underwent isolated coronary artery bypass grafting between January 1, 1990, and April 30, 1992, at a single nonprofit hospital. Overall hospital mortality was 4.06% (cardiac, 2.36%). Hospital morbidity was 14.25% (including mortality). Hospital costs (not charges) averaged $16,673 per patient. To explore the impact of preoperative EF, EF was stratified into regular intervals. Each interval was then compared with regard to hospital mortality, morbidity, and average costs. A new statistical tool, discharge analysis, was developed to analyze the cost data. This was necessary because previous efforts at cost analysis have used tools inappropriate for real world cost data. RESULTS: The statistical analysis showed that patients with EF of 0.40 or greater had the best outcomes (lowest mortality, morbidity, and cost). Once the EF is 0.40 or greater the EF does not carry further predictive value. At EF less than 0.40, patients with EF less than 0.30 have a poorer outcome than patients with EF of 0.30 to 0.39. CONCLUSIONS: (1) Ejection fraction is a valid predictor of mortality, morbidity and resource utilization based on statistical analysis. (2) Patients can be broadly grouped as having EF greater than 0.40, less than 0.30, or from 0.30 to 0.39 with regard to clinical and cost outcomes. (3) Postoperative length of stay is not predicted by risk-adjusted EF. (4) A new tool, discharge analysis, is presented to facilitate cost analysis.     

What is the marginal cost for marginal risk in cardiac surgery?

BACKGROUND: It has been shown that postoperative length of stay (LOS) correlates highly with mortality risk for cardiac surgical procedures. Similar correlations have been found for charges with LOS and costs with risk. METHODS: Postoperative LOS and risk scores were obtained, tabulated, and compiled into the five original Parsonnet risk groups for 2,589 patients who underwent cardiac operations from 1992 through 1996 at one hospital. The correlation of the group mean LOS with the group mean risk was tested. RESULTS: The correlation coefficient was 0.9827; 96.58% of the variance was removed using risk to predict LOS. A calculation of the difference in cost for difference in risk for cohorts of patients is developed. CONCLUSIONS: The high correlation of mean LOS with mean risk permits calculation of marginal cost for marginal risk based on clinical data. The marginal cost is equal to the difference in variable costs for cohorts.     

Case management of chronic ventilator patients. Reduce average length of stay and cost by half

The implementation of the case management model and the use of critical pathways has become a major strategy to improve quality of care and cope with measuring and managing costs. Grant Medical Center, a 640-bed Level I Trauma Center, began case managing its chronic ventilator patients in July, 1993. A 30-day critical pathway was developed using a multidisciplinary team approach. In case managing these patients, many problematic issues were identified, such as lack of adequate involvement by staff experienced in specific disciplines and multiple physician decision makers for each case. By increasing multidisciplinary collaboration, care of these patients was systematically changed and streamlined. Over a 2-year period, the average length of stay for chronic ventilator patients decreased from 74.5 days to 41.9 days, and the average cost per case decreased from $189,080 to $107,019.     

Clinical pathway across tertiary and community care after an interventional cardiology procedure

Many patients who receive medical interventional cardiology procedures at a tertiary hospital live outside the metropolitan area and may experience fragmentation in care, less emotional support by family members, inaccurate and delayed communication, and lack of educational follow-up on discharge from the hospital. A clinical pathway titled "Heart Health Care Patterns" was developed to link acute phase, recovery phase, rehabilitation phase, and enhancement/maintenance phase. The 12-month clinical pathway combines Gordon's Functional Health Patterns and the Omaha System developed by the Omaha Visiting Nurse Association. The rating scale for outcomes assesses the patient at different phases to provide objective data and information throughout the year.     

Use of demographic and clinical characteristics in predicting length of psychiatric hospital stay: A final evaluation.

The literature on patient demographic and clinical characteristics as predictors of length of psychiatric hospital stay suggests that investigators have been unsuccessful in producing a prediction model using this information to account for any substantial criterion variance. The present study maximized predictions of length of hospital stay by using a more powerful statistical procedure and an expanded number of predictor variables. Data were obtained on 877 patients who were discharged from psychiatric hospitals in 1980. Results show that despite these improvements, the resulting proportion of variance was moderate at best. It is concluded that increases in similar information are unlikely to improve predictions. The use of untapped variables (e.g., management philosophies and politically based information) is discussed. (14 ref) (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Agonist action at D2(long) dopamine receptors: ligand binding and functional assays

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.     

Dissecting microscope versus magnifying loupes with transillumination in the preparation of follicular unit grafts. A bilateral controlled study

OBJECTIVE: To review the morbidity and mortality among 68 premature infants treated with enterostomy for necrotizing enterocolitis. DESIGN: Data were collected retrospectively from hospital medical records to include the period between January 1, 1987, and September 30, 1997. SETTING: Tertiary care children's hospital. PATIENTS: A group of 68 infants aged 2 to 35 days (mean age, 12.5 days), weighing 1500 g or less, with necrotizing enterocolitis necessitating surgical enterostomy for treatment. INTERVENTIONS: Creation of any enterostomy during exploratory laparotomy for necrotizing enterocolitis and subsequent closure. MAIN OUTCOME MEASURES: Morbidity and mortality associated with infant enterostomy and its closure. RESULTS: Thirty-nine infants underwent ileostomy with mucous fistula, 16 underwent ileostomy with a Hartmann pouch, 7 had jejunostomy with mucous fistula, 2 had colostomy with mucous fistula, and 4 had colostomy with a Hartmann pouch. Eighteen (26%) of the 68 infants died in the postoperative period of sepsis (n = 10), continuing necrotizing enterocolitis (n = 5), or respiratory distress (n = 3). Of the remaining 50 infants, complications developed in 34 (68%). These complications included strictures requiring further resection at the time of enterostomy closure in 20 infants; stricture of the enterostomy requiring surgical revision in 6; incisional hernia in 3; parastomal hernia in 4; enterostomal prolapse or intussusception in 6 and 1, respectively; wound dehiscence in 4; wound infection in 8; small-bowel obstruction requiring laparotomy in 2; and anastomotic complications in 2. Only 16 enterostomies were closed uneventfully, with 3 of these infants subsequently dying of sudden infant death syndrome between 6 and 8 months after the operation. Of the surviving infants, 3 (6%) continue to require home hyperalimentation. CONCLUSIONS: Although enterostomy in infants with low birth weight with necrotizing enterocolitis may be lifesaving, it is also a major cause of morbidity. These data suggest the feasibility of a prospective study comparing resection and primary anastomosis with resection and enterostomy.     

Topical preparations for burns and their evaluation

Omission of a temporary ileostomy in patients undergoing restorative proctocolectomy is controversial. Although fewer operations may be required and some complications avoided, the risks of anastomotic dehiscence and pelvic sepsis may be greater. Patients undergoing restorative proctocolectomy with no ileostomy (Group NI, n = 72) were compared retrospectively with patients given a conventional loop ileostomy (Group I, n = 30). Criteria for avoiding faecal diversion included: absence of severe acute colitis, good nutritional status and favourable surgery with creation of a sound, tension-free anastomosis. Steroid intake was not a contraindication to single-stage surgery. Delayed stomas were necessary in 8% of Group NI. For Groups NI and I, the rates of anastomotic leak (3% vs 3%), pelvic sepsis without demonstrable leak (3% vs 0%), pouch fistula (3% vs 10%) and intestinal obstruction (8% vs 3%) were similar. Closure of the temporary ileostomy in Group I was associated with a 10% complication rate. Cumulative post-operative hospital stay was significantly less in Group NI (median 11 vs 16 days). Functional results at 1 year were similar. A temporary loop ileostomy can be safely avoided in carefully selected patients undergoing restorative proctocolectomy.     

Comparison of impedance cardiography with indirect Fick (CO2) method of measuring cardiac output in healthy children during exercise

Shortened hospital stays have decreased women's access to postpartum nursing care. Providers and payers together must address clinical and cost issues to develop a model of maternity care that covers the postpartum period. A short-stay maternity program was developed in 1989 by Professional Nurse Associates, Inc., in conjunction with Kaiser Permanente. The program includes prenatal preparation of families, a brief hospital stay, postpartum home visits, and postvisit case management. Readmission rates or mothers and newborns in the program have been less than 1%. The program has saved about $1 million a year since 1991, and consumer satisfaction has been measured at 99%.     

Issues in casemix funding for acute inpatient psychiatric services and their relevance to mental health nursing

With increased recognition by government, health administrators, and clinicians of the need to simultaneously contain health expenditure, improve the productivity and efficiency of health services and maintain quality of patient care, applications of casemix funding have been advocated as an alternative means of financing acute hospital care. Currently in Australia, the Commonwealth's casemix development program is encouraging the States and Territories to participate in certain casemix initiatives. Acute psychiatric hospital care and treatment have been excluded from the initial stages of the implementation of casemix in recognition of a number of inherent obstacles or challenges affecting the utility and accuracy of casemix in funding the psychiatric sector. Despite anecdotal claims that the reduced length of stay that often occurs under casemix payment systems may negatively impact upon the quality of care and patient outcomes, to date little empirical research has been directed towards measuring the potential impact of psychiatric casemix on the quality of patient care. Psychiatry cannot afford to ignore the casemix debate on account of its current exclusion from the early phases of implementation. To do so is to run the risk of having casemix imposed at some later stage in the absence of consultation. In the meantime it is vital that mental health professionals, including nurses, participate in the development and implementation of casemix, and contribute to research aimed at increasing or maximizing the relevance of casemix to the funding of psychiatric services.     

Effects of Medicare's prospective payment system on service use by depressed elderly inpatients

OBJECTIVE: To determine the effects of Medicare's prospective payment system (PPS) on hospital care, changes in length of stay and intensity of clinical services received by 2,746 depressed elderly patients in 297 acute care general medical hospitals were studied. METHODS: A pre-post design was used, and differences in sickness at admission were controlled for. Data on length of stay and use of specific clinical services were obtained from the medical record using a medical record abstraction form. Care provided on units exempt from PPS was compared with care provided in nonexempt units. RESULTS: After implementation of PPS, the average length of stay fell by up to three days within the different types of acute care settings studied, but this decline was partially offset by proportionately more admissions to psychiatric units, which had longer lengths of stay. Intensity of clinical services increased after PPS implementation, especially in nonexempt psychiatric units. CONCLUSION: Despite financial incentives for hospitals to reduce clinical services under PPS, its implementation was not associated with a marked decline in length of stay, when averaged across all treatment settings, and was associated with an increase in the intensity of many clinical services used by depressed elderly patients in general hospitals.
