Implementing a Standardized Constipation-Management Pathway to Reduce Resource Utilization

OBJECTIVE

Constipation is commonly diagnosed in our pediatric emergency department (ED). Care has varied significantly, with a heavy reliance on abdominal radiography (AR) for the diagnosis of and inpatient management for bowel cleanout. We implemented a standardized approach to caring for patients presenting to a pediatric ED with symptoms consistent with constipation, emphasizing clinical history, physical examination, less reliance on AR, and standardized home management.

METHODS

Using quality improvement (QI) methodology, a multidisciplinary group developed an ED constipation management pathway, encouraging less reliance on AR for diagnosis and promoting home management over inpatient bowel cleanout. The pathway included a home management "gift basket" containing over-the-counter medications and educational materials to promote successful bowel cleanout. Outcome measures included pathway utilization, AR rate, ED cost and length of stay, and ED admission rate for constipation.

RESULTS

Within 3 months, >90% of patients discharged home with an ED disposition diagnosis of constipation left with standardized educational materials and home medications. Staff education and feedback, pathway and gift basket changes, and a higher threshold for inpatient management led to significant decreases in AR rate (73.3%-24.6%, P < .001), average per-patient cost ($637.42-$538.85), length of stay (223-196 minutes, P < .001), and ED admission rate (15.3%-5.4%, P < .001), with no concerning missed diagnoses or increases in ED revisit rate.

CONCLUSIONS

An ED QI project standardizing the care of pediatric constipation was implemented successfully, leading to a sustainable decrease in resource utilization. The next phase of the project will focus on collaborating with community providers to reduce ED utilization.

Reducing Pediatric Sternal Wound Infections: A Quality Improvement Project

OBJECTIVES

To evaluate whether a quality improvement intervention reduces sternal wound infection rates in children after cardiac surgery.

DESIGN

This is a pre- and postintervention quality improvement study.

SETTING

A 16-bed cardiac ICU in a university-affiliated pediatric tertiary care children's hospital.

PATIENTS

All patients undergoing cardiac surgery via median sternotomy from January 2010 to December 2014 are included. The sternal wound infection rates for primary closure and delayed sternal closure are reported per 100 sternotomies. The hospital-acquired infection records were used to identify preintervention cases, while postintervention cases were collected prospectively.

INTERVENTION

Implementation of a sternal wound prevention bundle during the preoperative, intraoperative, and postoperative periods for cardiac surgical cases.

MEASUREMENTS AND MAIN RESULTS

During the preintervention period, 32 patients (3.8%) developed sternal wound infection, whereas only 19 (2.1%) developed sternal wound infection during the postintervention period (p = 0.04). The rates of sternal wound infection following primary closure were not significantly different pre- and postintervention (2.4% vs 1.6%; p = 0.35). However, patients with delayed sternal closure had significantly lower postintervention infection rates (10.6% vs 3.9%; p = 0.02).

CONCLUSIONS

Implementation of a sternal wound prevention bundle during the perioperative period was associated with lower sternal wound infection rates in surgeries with delayed sternal closure.

Implementing a clinical practice guideline for the treatment of bronchiolitis in a high-risk Hispanic pediatric population

INTRODUCTION

Bronchiolitis is the leading cause of hospitalization among infants and young children. Because of its frequency, a clinical practice guideline for bronchiolitis was implemented in this population in an effort to decrease costs and the number of diagnostic evaluations performed and medications used without increasing length of stay or transfers to the pediatric intensive care unit.

METHODS

A retrospective chart review of 322 pediatric admissions to a rural community hospital was conducted (169 before guideline implementation and 153 after guideline implementation), and data were categorically stratified into three groups for comparison purposes. Descriptive statistics were used to analyze the data, with a p value < .05 defining significance.

RESULTS

During the project period, patients with a mean age of 9.6 months were admitted to the hospital with bronchiolitis. Statistically significant decreases in cost per day and decreases in use of antibiotics and chest radiographs were achieved without increasing length of stay or pediatric intensive care unit transfers.

DISCUSSION

This project demonstrated feasibility in implementing an evidence-based clinical practice guideline in a rural hospital to improve patient outcomes.

Patterns of rehabilitation after hip arthroplasty and the association with outcomes: an episode of care view

OBJECTIVES

To examine the patterns of rehabilitation after elective and nonelective hip arthroplasty and its association with outcomes over an episode of postacute care.

DESIGN

Data were obtained from a multisite prospective observational cohort study and its companion follow-up study. Patterns of care were measured by the combination of settings of care where hip arthroplasty patients received rehabilitation therapy. Main outcome measure was motor portion of the functional independence measure.

RESULTS

Approximately 90% of hip arthroplasty patients received rehabilitation care from more than one setting. Eight patterns of care were identified in the follow-up period. Patterns of subsequent care were driven more by initial setting than by etiology. Nonelective hip arthroplasty patients had lower motor functional independence measure scores and used more rehabilitation services than did elective hip arthroplasty patients. Patterns of care were modest factors (accounted for only 7% of variance) in predicting patient motor functional independence measure over an episode of postacute care.

CONCLUSIONS

Etiology of hip arthroplasty is associated with amounts of rehabilitation care used and outcomes. After the initial postacute rehabilitation setting, patients continued to receive considerable amounts of therapy in various settings. It is important to look beyond a single setting of care to an entire episode of care when examining clinical outcomes.

Stage 2 pressure ulcer healing in nursing homes

OBJECTIVES

To identify resident and wound characteristics associated with Stage 2 pressure ulcer (PrU) healing time in nursing home residents.

DESIGN

Retrospective cohort study with convenience sampling.

SETTING

One hundred two nursing homes participating in the National Pressure Ulcer Long-Term Care Study (NPULS) in the United States.

PARTICIPANTS

Seven hundred seventy-four residents aged 21 and older with length of stay of 14 days or longer who had at least one initial Stage 2 (hereafter Stage 2) PrU.

MEASUREMENTS

Data collected for each resident over a 12-week period included resident characteristics and PrU characteristics, including area when first reached Stage 2. Data were obtained from medical records and logbooks.

RESULTS

There were 1,241 initial Stage 2 PrUs on 774 residents; 563 (45.4%) healed. Median time to heal was 46 days. Initial area was significantly associated with days to heal. Using Kaplan-Meier survival analyses, median days to heal was 33 for small (<or=1 cm(2)), 53 days for medium (>1 to <or=4 cm(2)), and 73 days for large (>4 cm(2)) ulcers. Using Cox proportional hazard regression models to examine effects of multiple variables simultaneously, small and medium ulcers and ulcers on residents with agitation and those who had oral eating problem healed more quickly, whereas ulcers on residents who required extensive assistance with seven to eight activities of daily living (ADLs), who temporarily left the facility for the emergency department (ED) or hospital, or whose PrU was on an extremity healed more slowly.

CONCLUSION

PrUs on residents with agitation or with oral eating problems were associated with faster healing time. PrUs located on extremities, on residents who went temporarily to the ED or hospital, and on residents with high ADL disabilities were associated with slower healing time. Interaction between PrU size and place of onset was also associated with healing time. For PrU onset before or after admission to the facility, smaller size was associated with faster healing time.

Opioid use and survival at the end of life: a survey of a hospice population

Concern that opioids hasten death may be among the reasons that pain is treated inadequately in populations with advanced illness. Studies that assess the true risks are needed. To determine whether survival after last opioid dose change is associated with opioid dosing characteristics and other factors, data from the National Hospice Outcomes Project, a large prospective cohort study involving 13 U.S. hospice programs, were analyzed. Of 1,306 patients, 725 received opioids and underwent at least one dose change before death. Subsamples based on maximum opioid dose compared patients receiving usual doses with those receiving high-dose therapy. Spearman rank correlations examined bivariate associations between survival after final dose change and other variables, including dose in morphine equivalent mg and percentage dose increase. Multivariate least squares regression analyses determined associations between survival and other variables, including those significant in bivariate analyses. The mean+/-SD number of days between final dose change and death was 12.46+/-23.11. Multivariate models demonstrated a significant association between shorter survival and higher opioid dose, a cancer diagnosis, unresponsiveness, and pain of <5 on a 0-10 scale, but none of these models explained >10% of the variance in time till death. Analyses of subsamples did not reveal additional effects of dose. This analysis revealed that opioid dosing was associated with time till death, but this factor would explain very little of the variation in survival. In a hospice population, survival is influenced by complex factors, many of which may not be measurable. Based on these findings, concern about hastening death does not justify withholding opioid therapy.

Prognostic models of abdominal wound dehiscence after laparotomy

BACKGROUND

Portions of the prospective, multi-institutional National Veterans Affairs Surgical Quality Improvement Program were used to develop and validate a perioperative risk index to predict abdominal wound dehiscence after laparotomy.

METHODS

Perioperative data from 17,044 laparotomies resulting in 587 (3.4%) wound dehiscences performed at 132 Veterans Affairs Medical Centers between October 1, 1996, and September 30, 1998, were used to develop the model. Data from 17,763 laparotomies performed between October 1, 1998, and September 30, 2000, resulting in 562 (3.2%) dehiscences were used to validate the model. Models were developed using multivariable stepwise logistic regression with preoperative, intraoperative, and postoperative variables entered sequentially as independent predictors of wound dehiscence. The model was used to create a scoring system, designated the abdominal wound dehiscence risk index.

RESULTS

Factors contributing significantly to the model and their point values (in parentheses) for the risk index include CVA with no residual deficit (4), history of COPD (4), current pneumonia (4), emergency procedure (6), operative time greater than 2.5 h (2), PGY 4 level resident as surgeon (3), clean wound classification (-3), superficial (5), or deep (17) wound infection, failure to wean from the ventilator (6), one or more complications other than dehiscence (7), and return to OR during admission (-11). Scores of 11-14 are predictive of 5% risk of dehiscence while scores of >14 predict 10% risk.

CONCLUSIONS

This abdominal wound dehiscence risk index identifies patients at risk for dehiscence and may be useful in guiding perioperative management.

Development of a pediatric age- and disease-specific severity measure

OBJECTIVES

To adapt the adult Comprehensive Severity Index (CSI) for hospitalized pediatric patients and evaluate the ability of the CSI to predict common outcomes.

STUDY DESIGN

Adult CSI was modified by a panel of pediatric subspecialists from 10 children's hospitals. Predictive power was evaluated by using retrospective data collected from 16,495 randomly selected children admitted to these hospitals from April 1995 through September 1996. Outcomes were mortality, length of stay (LOS), and cost.

RESULTS

Admission CSI score predicted mortality well (Hosmer-Lemeshow tests: P =.41-.98) and discriminated well (area under receiver operating characteristic [ROC] curve range = 0.80-0.99) within 9 case-mix groups with > or =10 deaths (P <.0001). Maximum CSI score explained the variation in LOS (r2 = 0.13-0.67) and cost (r2 = 0.08-0.73) within 32 case-mix groups (P <.005). Significant differences existed in admission and maximum average CSI scores across sites in 26 and 29 of 32 case-mix groups, respectively (P <.05). CSI had better predictability than Pediatric Risk of Mortality.

CONCLUSIONS

The age- and disease-specific pediatric CSI score correlates highly with LOS, cost, and mortality in hospitalized children and can help determine the best clinical practices for specific diseases and adjust for differences in severity of illness across providers.

Improving outcomes for patients hospitalized with CHF

Congestive Heart Failure is a costly debilitating medical condition that affects millions of elderly people. This Clinical Practice Improvement study was under taken to determine how variation in patient characteristics and clinical processes impact patient outcomes including length of stay, total charges, and increased severity of illness during hospitalization. The AHCPR Guideline for Heart Failure was used to evaluate clinical care. Data on patient characteristics including severity of illness and process of care were analyzed to determine which variables had the greatest impact on outcomes of care. Results showed that patient characteristics including comorbidities, severity of illness, and noncompliance with diet were significantly related to longer lengths of stay, higher charges, and/or increased severity (all covariates, p < .05). In addition, process of care variables including medication use and patient education significantly (p < .05) impacted outcomes of care. Findings have implications for the development of practice guidelines designed to improve patient outcomes associated with CHF hospitalizations.

Effect of practice variation on resource utilization in infants hospitalized for viral lower respiratory illness

OBJECTIVE

Hospital care for children with viral lower respiratory illness (VLRI) is highly variable, and its relationship to severity and impact on outcome is unclear. Using the Pediatric Comprehensive Severity Index, we analyzed the correlation of institutional practice variation with severity and resource utilization in 10 children's medical centers.

METHODS

Demographics, clinical information, laboratory results, interventions, and outcomes were extracted from the charts of consecutive infants with VLRI from 10 children's medical centers. Pediatric Component of the Comprehensive Severity Index scoring was performed at admission and at maximum during hospitalization. The correlation of patient variables, interventions, and resource utilization at the patient level was compared with their correlation at the aggregate institutional level.

RESULTS

Of 601 patients, 1 died, 6 were discharged to home health care, 4 were discharged to rehabilitative care, and 2 were discharged to chronic nursing care. Individual patient admission severity score correlated positively with patient hospital costs (r = 0.48), but institutional average patient severity was negatively correlated with average institutional costs (r = -0.26). Maximal severity score correlated well with costs (r = 0.66) and length of stay (LOS; r = 0.64) at the patient level but poorly at the institutional level (r = 0.07 costs; r = 0.40 LOS). The institutional intensity of therapy was negatively correlated with admission severity (r = -0.03) but strongly correlated with costs (r = 0.84) and LOS (r = 0.83).

CONCLUSIONS

Institutional differences in care practices for children with VLRI were not explained by differences in patient severity and did not affect the children's recovery but correlated significantly with hospital costs and LOS.

Severity assessment in children hospitalized with bronchiolitis using the pediatric component of the Comprehensive Severity Index

OBJECTIVE

Practice variation in the management of children hospitalized with bronchiolitis may result in significant differences in resource utilization. Determination of cost-effective care requires an objective means of adjusting for severity. We examined the correlation of the pediatric component of the Comprehensive Severity Index (CSI) with resource utilization in children hospitalized with bronchiolitis at ten children's medical centers.

DESIGN

Demographics, clinical findings, laboratory results, interventions, and outcomes were retrospectively extracted from the charts of 804 consecutive children with International Classification of Disease, Ninth Revision codes for bronchiolitis from 10 children's medical centers. Comorbidities of prematurity, heart disease, and a prior history of wheezing or hospitalization, and the viral etiology of the illness were specifically examined. CSI scoring was performed at admission and maximum and correlated with patient variables and measures of resource utilization (hospital costs, length of stay, pediatric intensive care unit admission, and intubation). The performance of CSI relative to the Pediatric Risk of Mortality III was also evaluated.

SETTING

Ten tertiary children's medical centers.

INTERVENTIONS

None.

MEASUREMENTS AND MAIN RESULTS

One child died and >99% of children returned to their baseline state of health. Admission CSI was comparable to the aggregate of all patient variables in its correlation with hospital costs (r2 = 0.23 vs. r2 = 0.24, respectively) and lengths of stay (r2 = 0.23 vs. r2 = 0.24, respectively). Maximum CSI had the highest correlation coefficient with hospital costs (r2 = 0.42) and lengths of stay (r2 = 0.41), whereas the correlation of admission Pediatric Risk of Mortality III scores with costs was r2 = 0.12 and with lengths of stay was r2 = 0.07. CSI scores also correlated well with measures of resource utilization in subgroups of bronchiolitis patients with comorbidities or other risk factors for severe disease.

CONCLUSIONS

CSI scores correlate well with resource use in pediatric patients hospitalized with bronchiolitis. This severity scoring system may be useful in assessing the cost-effectiveness of their care.
