Organisational culture: variation across hospitals and connection to patient safety climate.

CONTEXT: Bureaucratic organisational culture is less favourable to quality improvement, whereas organisations with group (teamwork) culture are better aligned for quality improvement. OBJECTIVE: To determine if an organisational group culture shows better alignment with patient safety climate. DESIGN: Cross-sectional administration of questionnaires. Setting 40 Hospital Corporation of America hospitals. PARTICIPANTS: 1406 nurses, ancillary staff, allied staff and physicians. MAIN OUTCOME MEASURES: Competing Values Measure of Organisational Culture, Safety Attitudes Questionnaire (SAQ), Safety Climate Survey (SCSc) and Information and Analysis (IA). RESULTS: The Cronbach alpha was 0.81 for the group culture scale and 0.72 for the hierarchical culture scale. Group culture was positively correlated with SAQ and its subscales (from correlation coefficient r = 0.44 to 0.55, except situational recognition), ScSc (r = 0.47) and IA (r = 0.33). Hierarchical culture was negatively correlated with the SAQ scales, SCSc and IA. Among the 40 hospitals, 37.5% had a hierarchical dominant culture, 37.5% a dominant group culture and 25% a balanced culture. Group culture hospitals had significantly higher safety climate scores than hierarchical culture hospitals. The magnitude of these relationships was not affected after adjusting for provider job type and hospital characteristics. CONCLUSIONS: Hospitals vary in organisational culture, and the type of culture relates to the safety climate within the hospital. In combination with prior studies, these results suggest that a healthcare organisation's culture is a critical factor in the development of its patient safety climate and in the successful implementation of quality improvement initiatives.

The SQUIRE (Standards for QUality Improvement Reporting Excellence) guidelines for quality improvement reporting: explanation and elaboration.

As the science of quality improvement in health care advances, the importance of sharing its accomplishments through the published literature increases. Current reporting of improvement work in health care varies widely in both content and quality. It is against this backdrop that a group of stakeholders from a variety of disciplines has created the Standards for QUality Improvement Reporting Excellence, which we refer to as the SQUIRE publication guidelines or SQUIRE statement. The SQUIRE statement consists of a checklist of 19 items that authors need to consider when writing articles that describe formal studies of quality improvement. Most of the items in the checklist are common to all scientific reporting, but virtually all of them have been modified to reflect the unique nature of medical improvement work. This "Explanation and Elaboration" document (E & E) is a companion to the SQUIRE statement. For each item in the SQUIRE guidelines the E & E document provides one or two examples from the published improvement literature, followed by an analysis of the ways in which the example expresses the intent of the guideline item. As with the E & E documents created to accompany other biomedical publication guidelines, the purpose of the SQUIRE E & E document is to assist authors along the path from completion of a quality improvement project to its publication. The SQUIRE statement itself, this E & E document, and additional information about reporting improvement work can be found at http://www.squire-statement.org.

Relationship between patient complaints and surgical complications.

BACKGROUND: Patient complaints are associated with increased malpractice risk but it is unclear if complaints might be associated with medical complications. The purpose of this study was to determine whether an association exists between patient complaints and surgical complications. METHODS: A retrospective analysis of 16,713 surgical admissions was conducted over a 54 month period at a single academic medical center. Surgical complications were identified using administrative data. The primary outcome measure was unsolicited patient complaints. RESULTS: During the study period 0.9% of surgical admissions were associated with a patient complaint. 19% of admissions associated with a patient complaint included a postoperative complication compared with 12.5% of admissions without a patient complaint (p = 0.01). After adjusting for surgical specialty, co-morbid illnesses and length of stay, admissions with complications had an odds ratio of 1.74 (95% confidence interval 1.01 to 2.98) of being associated with a complaint compared with admissions without complications. CONCLUSIONS: Admissions with surgical complications are more likely to be associated with a complaint than surgical admissions without complications. Further research is necessary to determine if patient complaints might serve as markers for poor clinical outcomes.

Using real time process measurements to reduce catheter related bloodstream infections in the intensive care unit.

PROBLEM: Measuring a process of care in real time is essential for continuous quality improvement (CQI). Our inability to measure the process of central venous catheter (CVC) care in real time prevented CQI efforts aimed at reducing catheter related bloodstream infections (CR-BSIs) from these devices. DESIGN: A system was developed for measuring the process of CVC care in real time. We used these new process measurements to continuously monitor the system, guide CQI activities, and deliver performance feedback to providers. SETTING: Adult medical intensive care unit (MICU). KEY MEASURES FOR IMPROVEMENT: Measured process of CVC care in real time; CR-BSI rate and time between CR-BSI events; and performance feedback to staff. STRATEGIES FOR CHANGE: An interdisciplinary team developed a standardized, user friendly nursing checklist for CVC insertion. Infection control practitioners scanned the completed checklists into a computerized database, thereby generating real time measurements for the process of CVC insertion. Armed with these new process measurements, the team optimized the impact of a multifaceted intervention aimed at reducing CR-BSIs. EFFECTS OF CHANGE: The new checklist immediately provided real time measurements for the process of CVC insertion. These process measures allowed the team to directly monitor adherence to evidence-based guidelines. Through continuous process measurement, the team successfully overcame barriers to change, reduced the CR-BSI rate, and improved patient safety. Two years after the introduction of the checklist the CR-BSI rate remained at a historic low. LESSONS LEARNT: Measuring the process of CVC care in real time is feasible in the ICU. When trying to improve care, real time process measurements are an excellent tool for overcoming barriers to change and enhancing the sustainability of efforts. To continually improve patient safety, healthcare organizations should continually measure their key clinical processes in real time.

The hemochromatosis C282Y allele: a risk factor for hepatic veno-occlusive disease after hematopoietic stem cell transplantation.

Hepatic veno-occlusive disease (HVOD) is a serious complication of hematopoietic stem cell transplantation (HSCT). Since the liver is a major site of iron deposition in HFE-associated hemochromatosis, and iron has oxidative toxicity, we hypothesized that HFE genotype might influence the risk of HVOD after myeloablative HSCT. We determined HFE genotypes in 166 HSCT recipients who were evaluated prospectively for HVOD. We also tested whether a common variant of the rate-limiting urea cycle enzyme, carbamyl-phosphate synthetase (CPS), previously observed to protect against HVOD in this cohort, modified the effect of HFE genotype. Risk of HVOD was significantly higher in carriers of at least one C282Y allele (RR=3.7, 95% CI 1.2-12.1) and increased progressively with C282Y allelic dose (RR=1.7, 95% CI 0.4-6.8 in heterozygotes; RR=8.6, 95% CI 1.5-48.5 in homozygotes). The CPS A allele, which encodes a more efficient urea cycle enzyme, reduced the risk of HVOD associated with HFE C282Y. We conclude that HFE C282Y is a risk factor for HVOD and that CPS polymorphisms may counteract its adverse effects. Knowledge of these genotypes and monitoring of iron stores may facilitate risk-stratification and testing of strategies to prevent HVOD, such as iron chelation and pharmacologic support of the urea cycle.

Cost perspectives of laparoscopic and open appendectomy.

BACKGROUND: Despite multiple studies comparing laparoscopic and open appendectomies, the clinically and economically superior procedure still is in question. A cost analysis was performed using both institutional and societal perspectives. METHODS: A decision analytic model was developed to evaluate laparoscopic and open appendectomies. The institutional perspective addressed direct health care costs, whereas the societal perspective addressed direct and indirect health care costs. Baseline values and ranges were taken from randomized controlled trials, meta-analyses, and Medicare databases. RESULTS: From the institutional perspective, open appendectomy is the least expensive strategy, with an expected cost of $5,171, as compared with $6,118 for laparoscopic appendectomy. The laparoscopic approach is less expensive if open appendectomy wound infection rates exceed 23%. From the societal perspective, laparoscopic appendectomy is the least expensive strategy, with an expected cost of $10,400, as compared with $12,055 for open appendectomy. CONCLUSIONS: The decision analysis demonstrated an economic advantage to the hospital of open appendectomy. In contrast, laparoscopic appendectomy represents a better economic choice for the patient.

Health-related quality of life before and after solid organ transplantation. Measurement consideration, reported outcomes, and future directions.

The initial focus in organ transplantation clinical research was demonstrating acceptable technical and survival outcomes. Both patient and graft survival have reached well-documented, laudable levels, and solid organ (liver, heart, kidney, lung) transplantation procedures are now relatively common. As with any complex medical procedure that entails relatively high risk, financial costs, and life-long follow-up care, reliable and valid assessments of the "quality" of the extended life years are of interest to patients, their families, policy makers, and payers. This review focuses on health-related quality of life (HRQOL) and functional performance in adults following solid organ transplantation, with an emphasis on: 1) instruments and methods; 2) outcomes in liver, heart, kidney, and lung transplant recipients; and 3) future research directions. Practical considerations for developing longitudinal HRQOL assessment strategies are reviewed. The current emphasis on modeling demographic and clinical factors that promote or limit optimal HRQOL is illustrated. These lines of research will help identify potential interventions designed to promote better HRQOL in organ transplant recipients.

Predictors of influenza virus vaccination status in hospitalized children.

OBJECTIVE: To determine predictors of influenza virus vaccination status in children who are hospitalized during the influenza season. METHODS: A cross-sectional study was conducted among children who were hospitalized with fever between 6 months and 3 years of age or with respiratory symptoms between 6 months and 18 years of age. The 1999 to 2000 influenza vaccination status of hospitalized children and potential factors that influence decisions to vaccinate were obtained from a questionnaire administered to parents/guardians. RESULTS: Influenza vaccination rates for hospitalized children with and without high-risk medical conditions were 31% and 14%, respectively. For both groups of children, the vaccination status was strongly influenced by recommendations from physicians. More than 70% of children were vaccinated if a physician had recommended the influenza vaccine, whereas only 3% were vaccinated if a physician had not. Lack of awareness that children can receive the influenza vaccine was a commonly cited reason for nonvaccination. CONCLUSIONS: A minority of hospitalized children with high-risk conditions had received the influenza vaccine. However, parents' recalling that a clinician had recommended the vaccine had a positive impact on the vaccination status of children.

Delirium in mechanically ventilated patients: validity and reliability of the confusion assessment method for the intensive care unit (CAM-ICU).

CONTEXT: Delirium is a common problem in the intensive care unit (ICU). Accurate diagnosis is limited by the difficulty of communicating with mechanically ventilated patients and by lack of a validated delirium instrument for use in the ICU. OBJECTIVES: To validate a delirium assessment instrument that uses standardized nonverbal assessments for mechanically ventilated patients and to determine the occurrence rate of delirium in such patients. DESIGN AND SETTING: Prospective cohort study testing the Confusion Assessment Method for ICU Patients (CAM-ICU) in the adult medical and coronary ICUs of a US university-based medical center. PARTICIPANTS: A total of 111 consecutive patients who were mechanically ventilated were enrolled from February 1, 2000, to July 15, 2000, of whom 96 (86.5%) were evaluable for the development of delirium and 15 (13.5%) were excluded because they remained comatose throughout the investigation. MAIN OUTCOME MEASURES: Occurrence rate of delirium and sensitivity, specificity, and interrater reliability of delirium assessments using the CAM-ICU, made daily by 2 critical care study nurses, compared with assessments by delirium experts using Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, criteria. RESULTS: A total of 471 daily paired evaluations were completed. Compared with the reference standard for diagnosing delirium, 2 study nurses using the CAM-ICU had sensitivities of 100% and 93%, specificities of 98% and 100%, and high interrater reliability (kappa = 0.96; 95% confidence interval, 0.92-0.99). Interrater reliability measures across subgroup comparisons showed kappa values of 0.92 for those aged 65 years or older, 0.99 for those with suspected dementia, or 0.94 for those with Acute Physiology and Chronic Health Evaluation II scores at or above the median value of 23 (all P<.001). Comparing sensitivity and specificity between patient subgroups according to age, suspected dementia, or severity of illness showed no significant differences. The mean (SD) CAM-ICU administration time was 2 (1) minutes. Reference standard diagnoses of delirium, stupor, and coma occurred in 25.2%, 21.3%, and 28.5% of all observations, respectively. Delirium occurred in 80 (83.3%) patients during their ICU stay for a mean (SD) of 2.4 (1.6) days. Delirium was even present in 39.5% of alert or easily aroused patient observations by the reference standard and persisted in 10.4% of patients at hospital discharge. CONCLUSIONS: Delirium, a complication not currently monitored in the ICU setting, is extremely common in mechanically ventilated patients. The CAM-ICU appears to be rapid, valid, and reliable for diagnosing delirium in the ICU setting and may be a useful instrument for both clinical and research purposes.

Nonenhanced limited CT in children suspected of having appendicitis: prospective comparison of attending and resident interpretations.

PURPOSE: To prospectively compare resident and attending radiologic interpretations of nonenhanced limited computed tomographic (CT) scans obtained in children suspected of having appendicitis. MATERIALS AND METHODS: Seventy-five consecutive children underwent nonenhanced limited CT for suspected appendicitis. The scans were prospectively interpreted by a resident and an attending radiologist, each unaware of the other's interpretation. The probability that the findings indicated a diagnosis of appendicitis, level of certainty in the interpretation, and presence of an alternate diagnosis were statistically analyzed. RESULTS: Nineteen children (25%) had appendicitis. The area under the receiver operating characteristic curve was not significantly different between residents (0.97 +/- 0.02) and attendings (0.95 +/- 0.04). The percentage agreement between residents and attendings was 91% (kappa = 0.73 +/- 0.095). The average level of certainty tended to be higher for attendings (93% +/- 15) than residents (89% +/- 12). The sensitivity, specificity, and accuracy of resident interpretations were 63%, 96%, and 88%, respectively, compared with those of attending interpretations--95%, 98%, and 97%, respectively. Residents and attendings noted alternate diagnoses in 30% of children without appendicitis. CONCLUSION: A high level of agreement exists between resident and attending radiologists in the interpretation of nonenhanced limited CT scans in children suspected of having appendicitis. Residents, however, tend to be less confident in their interpretations.

Patients' values for health states associated with hepatitis C and physicians' estimates of those values.

OBJECTIVES: Hepatitis C is the leading cause of chronic hepatitis in the United States. Little information is available regarding how persons with hepatitis C view health with their disease. We studied patients' perceptions about the value of hepatitis C health states and evaluated whether physicians understand their patients' perspectives about this disease. METHODS: A total of 50 consecutive persons with hepatitis C were surveyed when they presented as new patients to a hepatology practice. Subjects provided utility assessments (preference values) for five hepatitis C health states and for treatment side effects. They also stated their threshold for accepting antiviral therapy. Five hepatologists used the same scales to estimate their patients' responses. RESULTS: On average, patients believed that hepatitis C without symptoms was associated with an 11% reduction in preference value from that of life without infection, and the most serious condition (severe symptoms, cirrhosis) was believed to carry a 73% decrement. Patients judged the side effects of antiviral therapy quite unfavorably, and their median stated threshold for accepting treatment was a cure rate of 80%. Physicians' estimates were not significantly associated with patients' preference values for hepatitis C health states, treatment side effects, or with patients' thresholds for accepting treatment. In multivariate analysis, patients' stated thresholds for taking treatment were significantly associated with their decisions regarding therapy (beta = -2.72+/-1.21, p = 0.025). CONCLUSIONS: There was little agreement between patients' preference values about hepatitis C and their physicians' estimates of those values. Utility analysis could facilitate shared decision making about hepatitis C.

Evaluation of delirium in critically ill patients: validation of the Confusion Assessment Method for the Intensive Care Unit (CAM-ICU).

OBJECTIVE: To develop and validate an instrument for use in the intensive care unit to accurately diagnose delirium in critically ill patients who are often nonverbal because of mechanical ventilation. DESIGN: Prospective cohort study. SETTING: The adult medical and coronary intensive care units of a tertiary care, university-based medical center. PATIENTS: Thirty-eight patients admitted to the intensive care units. MEASUREMENTS AND MAIN RESULTS: We designed and tested a modified version of the Confusion Assessment Method for use in intensive care unit patients and called it the CAM-ICU. Daily ratings from intensive care unit admission to hospital discharge by two study nurses and an intensivist who used the CAM-ICU were compared against the reference standard, a delirium expert who used delirium criteria from the Diagnostic and Statistical Manual of Mental Disorders (fourth edition). A total of 293 daily, paired evaluations were completed, with reference standard diagnoses of delirium in 42% and coma in 27% of all observations. To include only interactive patient evaluations and avoid repeat-observer bias for patients studied on multiple days, we used only the first-alert or lethargic comparison evaluation in each patient. Thirty-three of 38 patients (87%) developed delirium during their intensive care unit stay, mean duration of 4.2 +/- 1.7 days. Excluding evaluations of comatose patients because of lack of characteristic delirium features, the two critical care study nurses and intensivist demonstrated high interrater reliability for their CAM-ICU ratings with kappa statistics of 0.84, 0.79, and 0.95, respectively (p <.001). The two nurses' and intensivist's sensitivities when using the CAM-ICU compared with the reference standard were 95%, 96%, and 100%, respectively, whereas their specificities were 93%, 93%, and 89%, respectively. CONCLUSIONS: The CAM-ICU demonstrated excellent reliability and validity when used by nurses and physicians to identify delirium in intensive care unit patients. The CAM-ICU may be a useful instrument for both clinical and research purposes to monitor delirium in this challenging patient population.

The impact of delirium in the intensive care unit on hospital length of stay.

STUDY OBJECTIVE: To determine the relationship between delirium in the intensive care unit (ICU) and outcomes including length of stay in the hospital. DESIGN: A prospective cohort study. SETTING: The adult medical ICU of a tertiary care, university-based medical center. PARTICIPANTS: The study population consisted of 48 patients admitted to the ICU, 24 of whom received mechanical ventilation. MEASUREMENTS: All patients were evaluated for the development and persistence of delirium on a daily basis by a geriatric or psychiatric specialist with expertise in delirium assessment using the Diagnostic Statistical Manual IV (DSM-IV) criteria of the American Psychiatric Association, the reference standard for delirium ratings. Primary outcomes measured were length of stay in the ICU and hospital. RESULTS: The mean onset of delirium was 2.6 days (S.D.+/-1.7), and the mean duration was 3.4+/-1.9 days. Of the 48 patients, 39 (81.3%) developed delirium, and of these 29 (60.4%) developed the complication while still in the ICU. The duration of delirium was associated with length of stay in the ICU ( r=0.65, P=0.0001) and in the hospital ( r=0.68, P<0.0001). Using multivariate analysis, delirium was the strongest predictor of length of stay in the hospital ( P=0.006) even after adjusting for severity of illness, age, gender, race, and days of benzodiazepine and narcotic drug administration. CONCLUSIONS: In this patient cohort, the majority of patients developed delirium in the ICU, and delirium was the strongest independent determinant of length of stay in the hospital. Further study and monitoring of delirium in the ICU and the risk factors for its development are warranted.

Health-related quality of life after different types of solid organ transplantation.

OBJECTIVE: To describe functional health and health-related quality of life (QOL) before and after transplantation; to compare and contrast outcomes among liver, heart, lung, and kidney transplant patients, and compare these outcomes with selected norms; and to explore whether physiologic performance, demographics, and other clinical variables are predictors of posttransplantation overall subjective QOL. SUMMARY BACKGROUND DATA: There is increasing demand for outcomes analysis, including health-related QOL, after medical and surgical interventions. Because of the high cost, interest in transplantation outcomes is particularly intense. With technical surgical experience and improved immunosuppression, survival after solid organ transplantation has matured to acceptable levels. More sensitive measures of outcomes are necessary to evaluate further developments in clinical transplantation, including data on objective functional outcome and subjective QOL. METHODS: The Karnofsky Performance Status was assessed objectively for patients before transplantation and up to 4 years after transplantation, and scores were compared by repeated measures analysis of variance. Subjective evaluation of QOL over time was obtained using the Short Form-36 (SF-36) and the Psychosocial Adjustment to Illness Scale (PAIS). These data were analyzed using multivariate and univariate analysis of variance. A summary model of health-related QOL was tested by path analysis. RESULTS: Tools were administered to 100 liver, 94 heart, 112 kidney, and 65 lung transplant patients. Mean age at transplantation was 48 years; 36% of recipients were female. The Karnofsky Performance Status before transplantation was 37 +/- 1 for lung, 38 +/- 2 for heart, 53 +/- 3 for liver, and 75 +/- 1 for kidney recipients. After transplantation, the scores improved to 67 +/- 1 at 3 months, 77 +/- 1 at 6 months, 82 +/- 1 at 12 months, 86 +/- 1 at 24 months, 84 +/- 2 at 36 months, and 83 +/- 3 at 48 months. When patients were stratified by initial performance score as disabled or able, both groups merged in terms of performance by 6 months after liver and heart transplantation; kidney transplant patients maintained their stratification 2 years after transplantation. The SF-36 physical and mental component scales improved after transplantation. The PAIS score improved globally. Path analysis demonstrated a direct effect on the posttransplant Karnofsky score by time after transplantation and diabetes, with trends evident for education and preoperative serum creatinine level. Although neither time after transplantation nor diabetes was directly predictive of a composite QOL score that incorporated all 15 subjective domains, recent Karnofsky score and education level were directly predictive of the QOL composite score. CONCLUSIONS: Different types of transplant patients have a different health-related QOL before transplantation. Performance improved after transplantation for all four types of transplants, but the trajectories were not the same. Subjective QOL measured by the SF-36 and the PAIS also improved after transplantation. Path analysis shows the important predictors of health-related QOL. These data provide clearly defined and widely useful QOL outcome benchmarks for different types of solid organ transplants.

Increased risk of death in patients with do-not-resuscitate orders.

BACKGROUND: Whereas studies have shown higher mortality rates in patients with do-not-resuscitate (DNR) orders, most have not accounted for confounding factors related to the use of DNR orders and/or factors related to the risk of death. OBJECTIVE: To determine the relationship between the use of DNR orders and in-hospital mortality, adjusting for severity of illness and other covariates. DESIGN: Retrospective cohort study. PATIENTS: There were 13,337 consecutive stroke admissions to 30 hospitals in 1991 to 1994. MEASURES: To decrease selection bias, propensity scores reflecting the likelihood of a DNR order were developed. Scores were based on nine demographic and clinical variables independently related to use of DNR orders. The odds of death in patients with DNR orders were then determined using logistic regression, adjustment for propensity scores, severity of illness, and other factors. RESULTS: DNR orders were used in 22% (n = 2,898) of patients. In analyses examining DNR orders written at any time during hospitalization, unadjusted in-hospital mortality rates were higher in patients with DNR orders than in patients without orders (40% vs. 2%, P<0.001); the adjusted odds of death was 33.9 (95% CI, 27.4-42.0). The adjusted odds of death remained higher in analyses that only considered orders written during the first 2 days (OR 3.7; 95% CI, 3.2-4.4) or the first day (OR 2.4; 95% CI, 2.0-2.9). In stratified analyses, adjusted odds of death tended to be higher in patients with lower propensity scores. CONCLUSION: The risk of death was substantially higher in patients with DNR orders after adjusting for propensity scores and other covariates. Whereas the increased risk may reflect patient preferences for less intensive care or unmeasured prognostic factors, the current findings highlight the need for more direct evaluations of the quality and appropriateness of care of patients with DNR orders.

Improving health care, Part 5: Applying the Dartmouth clinical improvement model to community health.

BACKGROUND: Traditional approaches to community health initiatives provide guidance on community mobilization, health assessment, planning, and intervention. Yet direction in how to frame the action steps to implement and measure results is often missing. Many community health initiatives find implementation overwhelming and ineffectual. FRAMEWORK FOR COMMUNITY HEALTH-THE CLINICAL IMPROVEMENT MODEL: The process--outcome methodology of continuous quality improvement (CQI) can translate large community aims into manageable projects. The sequential application of the clinical improvement model and the Community Health Value Compass for measuring outcomes-in state of health, quality of life, satisfaction, and costs-provides a link between data and action, thereby producing accountability for the community health initiative. USING THE CLINICAL IMPROVEMENT MODEL IN TWIN FALLS: Healthy Magic Valley (Twin Falls, Idaho) is the vision for long-term improvement in health status and reduction of health risks for the Southcentral Idaho Health Network. Since 1996 the Twin Falls Community Health Collaborative and SAFE KIDS Coalition have used the Value Compass model and CQI methods to decrease the rate of motor vehicle collisions, serious injuries, and deaths involving teens, while reducing the health, educational, legal, and financial consequences associated with teen-involved motor vehicle collisions. In 1993 the Twin Falls collaborative convened to apply CQI methods to the health of the community. The team has since met periodically to address the issues of community health, using the Dartmouth value compass model since 1996. Each sequential application of the process-outcome CQI framework exposes a blueprint for action and the unfolding of a health improvement strategy. The interventions should affect one or more dimensions of the value compass for teenage driving and motor vehicle collisions. CASE STUDY OF THE CLINICAL IMPROVEMENT MODEL: The motor vehicle death in October 1997 of a high school football player, who was not wearing a seat belt, led to a call to action for injury prevention. Implementation of a local community health initiative on seat belt use started in 1998. A strategy was developed to address implementation of the project among high school teens (for immediate impact) and elementary school children (for long-term impact) and to promote collaboration between the school and the rest of the community. RESULTS: Observed use of seat belts increased from January to September 1998. Data on fatality rates; injury rates; percentages of teens in crashes, of teens injured, and of teen collisions involving use of alcohol; and comprehensive costs are also monitored. DISCUSSION: Once coalitions are built and priorities set, the Dartmouth clinical improvement model presents a method that emphasizes measuring the benefits to the individual members of the community. A portfolio composed of a value compass for each health improvement initiative provides ongoing feedback for guiding subsequent strategic planning by the governing community health network.

A firm trial of interdisciplinary rounds on the inpatient medical wards: an intervention designed using continuous quality improvement.

OBJECTIVES: In August 1993 a group of house staff and nursing staff at MetroHealth Medical Center formed a quality improvement team to evaluate the process of medical care on the inpatient wards. Using standard continuous quality improvement (CQI) methods, a team of medical interns, nurses, and other health professionals involved in patient care on the medicine inpatient service designed interdisciplinary, daily work rounds to improve the care of patients on the inpatient wards. METHODS: The authors conducted a randomized, controlled firm trial of the impact of interdisciplinary rounds on the inpatient medicine services. The trial lasted 6 months (November 1993-April 1994) and included 1,102 admissions randomly assigned to experimental or control teams by the pre-existing firm system. Of the 1,102 admissions included in the study, 535 were randomized to medical services with traditional rounds and 567 to medical services with interdisciplinary rounds. The outcomes studied included length of stay (LOS), total hospital charges, provider satisfaction, and ancillary service efficiency. RESULTS: Unadjusted analysis for log-transformed data showed lower length of stay and total charges for the interdisciplinary group. The mean LOS for interdisciplinary rounds was 5.46 days, compared with 6.06 days for traditional care (P = 0.006), whereas mean total charges were $6,681 and $8,090 (P = 0.002) for the two groups, respectively. After multivariate regression analysis using a propensity score that included gender, age, marital status, admission source, diagnosis-related group (DRG) weight, and primary diagnosis by International Classification of Diseases, Ninth Revision (ICD-9) cluster, these differences remained statistically significant. CONCLUSIONS: Previous studies of interdisciplinary teams have failed to show statistically significant cost savings. This study involving more patients shows both cost and LOS decreases with the use of interdisciplinary teams. At the end of the 6-month trial, interdisciplinary rounds were instituted on all medicine inpatient services.
