Costs of care associated with non-small-cell lung cancer in a commercially insured cohort

PURPOSE: To examine the cost of incident cases of non-small-cell lung cancer (NSCLC) in a commercially insured cohort. METHODS: Claims from Virginia Blue Cross and Blue Shield (BCBS) beneficiaries with lung cancer from 1989 to 1991 were merged with records from the Virginia Cancer Registry (VCR). Data from the VCR identified incident cases, stage, and type of cancer at diagnosis. Costs for all medical care included insurance payment, copayments, and deductibles for 2 years after diagnosis or until death. RESULTS: Three hundred forty-nine incident NSCLC patients were evaluated. The mean 2-year cost for each patient after diagnosis or until death was $47,941 (95% confidence interval, $43,758 to $52,124). Total average costs and hospital days were significantly lower for local disease ($37,514, 21.2 days), but were similar for regional ($52,797, 30.0 days) and distant ($49,382, 33.0 days) disease. Hospital days accounted for 48% and hospital-based claims for 70% of costs. Initial treatments, which included radiation, unadjusted for stage, had the lowest survival rates and the highest costs, and were associated with the most hospital days. Initial stage, race, gender, and age were not predictors of total 2-year costs. The independent predictors of total 2-year costs were type of treatment: any radiation therapy, any surgery, or any chemotherapy (all, P < .001). Inpatient hospital days was only a modest predictor of costs after adjusting for type of treatment. Patients who survived less than 1 year spent 30.5 days in hospital and had an average cost of $47,280. CONCLUSION: The direct health care costs of younger NSCLC patients care are substantial. These results should serve as a benchmark for future comparisons as the United States market shifts to managed care.     

Association of symptoms of depression with diagnostic test charges among older adults

BACKGROUND: Previous studies have documented greater use of health services by depressed persons and have postulated that health care costs could be reduced overall through better recognition and treatment of depression. OBJECTIVE: To determine whether a greater burden of medical illness contributes to excess charges for diagnostic tests among older adults with symptoms of depression. DESIGN: Prospective cohort study. SETTING: A primary care group practice at an academic institution. PATIENTS: 3767 patients 60 years of age and older who completed testing on the Centers for Epidemiologic Studies Depression Scale (CES-D) during routine office visits. MEASUREMENTS: Charges for all inpatient and ambulatory diagnostic testing for 2 years, including clinical pathology, diagnostic imaging, and special procedures; number of visits to the ambulatory care center or emergency department; and number of hospitalizations. The Ambulatory Care Group case-mix approach, which is based on ambulatory diagnoses, was used as a measure of health status and expected resource consumption. RESULTS: Patients with symptoms of depression (CES-D scores > or = 16) were significantly younger (66.6 compared with 68.1 years; P < 0.001), more likely to be white (50.5% compared with 33.9%; P = 0.001), and more likely to be female (75.8% compared with 67.6%; P = 0.001) than were those without these symptoms (CES-D scores < 16). They also had more nonpsychiatric comorbid conditions, had more visits to the ambulatory care center (9.2 compared with 7.8; P < 0.001), were more likely to use the emergency department (52.3% compared with 40%; P = 0.001), were more likely to be hospitalized (22.4% compared with 17%; P = 0.002), and had greater median total diagnostic test charges for a period of 1 year ($583 compared with $387; P < 0.001). The difference in charges, most of which were clinical pathology charges (54.2%), persisted into the second year. Ambulatory Care Group assignment was independently associated with diagnostic test charges. The CES-D summary score was not independently associated with diagnostic test charges when controlling for Ambulatory Care Group assignment. CONCLUSIONS: Patients with symptoms of depression accrue greater average diagnostic test charges. However, these data suggest that such patients also have a greater burden of comorbid nonpsychiatric illness. Efforts to improve outcome and decrease cost for patients who have late-life depression must target interventions to improve the care of psychiatric and medical illness concurrently.     

Effects of galanin on 8-OH-DPAT induced decrease in body temperature and brain 5-hydroxytryptamine metabolism in the mouse

The objective of this study was to describe the health care utilization and prospective predictors of high-cost primary-care back pain patients. In the primary-care clinics of a large, staff model health maintenance organization in western Washington State, 1059 subjects were selected from consecutive patients presenting for back pain. The design was a 1-year prospective cohort study. Patients' were interviewed 1 month after an index primary-care back pain visit. Costs (back pain and total) and utilization (back pain primary-care follow-up visits, back pain specialty visits, back pain hospitalizations, back pain radiologic procedures, and pain medicine fills) were tracked over the next 11 months. Predictors assessed at 1 month were back pain diagnosis (disc disorder/sciatica, arthritis, vs. other), chronic pain grade (measure of pain intensity and related dysfunction), pain persistence (days with pain in prior 6 months), depressive symptomatology, and back pain-related disability compensation (ever/never). For the sample, 21% of patients with back pain costs > or = $600 (high back pain costs) accounted for 66% of back pain costs, 42% of total costs, 55% of primary-care follow-up visits for back pain, 91% of back pain specialty visits, 100% of back pain hospitalizations, 51% of back pain radiologic procedures, and 52% of pain medicine fills. The 21% with total costs > or = $2700 (high total costs) accounted for 67.7% of total costs, 52% of back pain costs, 29% of primary-care follow-up visits for back pain, 66% of back pain specialty visits, 100% of back pain hospitalizations, 39% of back pain radiologic procedures, and 42% of pain medicine fills. Multivariable logistic regression analyses indicated that increasing chronic pain grade, more persistent pain, and disc disorder/sciatica were strong independent predictors of high total and high back pain costs. Increasing depressive symptoms significantly predicted high total but not high back pain costs. Back pain disability compensation predicted high back pain but not high total costs. A minority of primary-care back pain patients accounted for a majority of health-care costs. Patients with high back pain costs accounted for more back pain-related health-care utilization than did patients with high total costs. Factors predicting subsequent high costs suggest behavioral interventions targeting dysfunction, pain persistence, and depression may reduce health-care utilization and prevent accumulation of high health-care costs among primary-care back pain patients.     

Cost-effectiveness model of adjunctive lamotrigine for the treatment of epilepsy

OBJECTIVE: To predict the cost-effectiveness of lamotrigine by evaluating the costs and health outcomes in treated patients. BACKGROUND: Lamotrigine adjunctive therapy has been found to be associated with decreased seizure frequency and severity in patients who are refractory to treatment with the older antiepileptic drugs (AEDs). METHODS: We used a cost-effectiveness clinical decision analysis framework to assess the impact of these clinical benefits on patient health care use. The measure of effectiveness was seizure-free days gained. The measures of health care resource use included hospitalizations, outpatient and emergency department visits, surgery, and AEDs. Medical care use and cost estimates were derived from clinical trial data and published sources. Costs and effectiveness (incremental costs per seizure-free days gained) of lamotrigine adjunctive therapy versus older AEDs were compared in patients refractory to previous treatment during three time periods: the start-up year, the second year when decisions about surgery were made, and all subsequent years. RESULTS AND CONCLUSIONS: The model predicts that use of lamotrigine would be associated with an overall reduction in use of other direct medical care resources (hospitalizations, outpatient visits, diagnostic and laboratory tests, and surgery). For a 10-year time horizon, the estimated cost-effectiveness ratio is $6.9 per seizure-free day gained. The model provides a flexible framework to analyze the effect of new antiepileptic drugs.     

Ambulatory health care use by patients in a public hospital emergency department

OBJECTIVE: To describe primary care clinic use and emergency department (ED) use for a cohort of public hospital patients seen in the ED, identify predictors of frequent ED use, and ascertain the clinical diagnoses of those with high rates of ED use. DESIGN: Cohort observational study. SETTING: A public hospital in Atlanta, Georgia. PATIENTS: Random sample of 351 adults initially surveyed in the ED in May 1992 and followed for 2 years. MEASUREMENTS AND MAIN RESULTS: Of the 351 patients from the initial survey, 319 (91%) had at least one ambulatory visit in the public hospital system during the following 2 years and one third of the cohort was hospitalized. The median number of subsequent ED visits was 2 (mean 6.4), while the median number of visits to a primary care appointment clinic was O (mean 1.1) with only 90 (26%) of the patients having any primary care clinic visits. The 58 patients (16.6%) who had more than 10 subsequent ED visits accounted for 65.6% of all subsequent ED visits. Overall, patients received 55% of their subsequent ambulatory care in the ED, with only 7.5% in a primary care clinic. In multivariate regression, only access to a telephone (odds ratio [OR] 0.48; 95% confidence interval [CI] 0.39, 0.60), hospital admission (OR 5.90; 95% CI 4.01, 8.76), and primary care visits (OR 1.68; 95% CI 1.34, 2.12) were associated with higher ED visit rates. Regular source of care, insurance coverage, and health status were not associated with ED use. From clinical record review, 74.1% of those with high rates of use had multiple chronic medical conditions, or a chronic medical condition complicated by a psychiatric diagnosis, or substance abuse. CONCLUSIONS: All subgroups of patients in this study relied heavily on the ED for ambulatory care, and high ED use was positively correlated with appointment clinic visits and inpatient hospitalization rates, suggesting that high resource utilization was related to a higher burden of illness among those patients. The prevalence of chronic medical conditions and substance abuse among these most frequent emergency department users points to a need for comprehensive primary care. Multidisciplinary case management strategies to identify frequent ED users and facilitate their use of alternative care sites will be particularly important as managed care strategies are applied to indigent populations who have traditionally received care in public hospital EDs.     

Cost-effectiveness of the arthritis self-help course

OBJECTIVE: To evaluate the cost-effectiveness of the Arthritis Self-Help Course in reducing the pain of arthritis, the leading cause of disability in the United States and a common problem among older adults. METHODS: A decision model was used to examine the cost-effectiveness of the Arthritis Self-Help Course among individuals with arthritis over a 4-year analytic horizon from 2 perspectives, namely, society and the health care system. The Arthritis Self-Help Course was assumed to reduce pain by 20% and physician visits for arthritis by 40% among individuals receiving conventional medical therapy. Estimates for program costs, costs for physician visits, and time and transportation costs were derived from the published literature and expert opinion. Sensitivity analyses were conducted on all relevant parameters. Arthritis pain and costs (program, physician visit plus/minus time and transportation) were expressed as cost per person per unit reduction in pain. Because nearly all analyses showed the program to be cost saving, we simply report the reduction in joint pain and the cost savings, because standardizing cost savings is not a useful concept. RESULTS: From both the societal and health care system perspectives, the Arthritis Self-Help Course was cost saving in base-case analyses (reducing pain by 0.9 units while saving $320 and $267, respectively) and throughout the range of reasonable values used in univariate sensitivity analyses. Cost savings were due primarily to reduced physician visits. CONCLUSIONS: The Arthritis Self-Help Course is a cost-saving intervention that further reduces arthritis pain among individuals receiving conventional medical therapy. The benefits for both patients and health care providers warrant its more widespread use as a normal adjunct to conventional therapy.     

Risk factors for higher cost in congenital heart operations

BACKGROUND: For many congenital heart defects, hospital mortality is no longer a sensitive parameter by which to measure outcome. Although hospital survival rates are now excellent for a wide variety of lesions, many patients require expensive and extensive hospital-based services during the perioperative period to enable their convalescence. These services can substantially increase the cost of care delivery. In today's managed care environment, it would be useful if risk factors for higher cost could be identified preoperatively so that appropriate resources could be made available for the care of these patients. The focus of this retrospective investigation is to determine if risk factors for high cost for repair of congenital heart defects can be identified. METHODS: We assessed financial risk by tracking actual hospital costs (not charges) for 144 patients undergoing repair of atrial septal defect (58 patients), ventricular septal defect (48 patients), atrioventricular canals (14 patients), or tetralogy of Fallot (24 patients) at Duke University Medical Center between July 1, 1992, and September 15, 1995. Furthermore, we were able to identify where the costs occurred within the hospital. Financial risk was defined as a large (> 60% of mean costs) standard deviation, which indicated unpredictability and variability in the treatment for a group of patients. RESULTS: Cost for atrial septal defect repair was predictably consistent (low standard deviation) and was related to hospital length of stay. There were factors, however, for ventricular septal defect, atrioventricular canal, and tetralogy of Fallot repair that are identifiable preoperatively that predict low- and high-risk groups using cost as an outcome parameter. Patients undergoing ventricular septal defect repair who were younger than 6 months of age at the time of repair, who required preoperative hospital stays of longer than 7 days before surgical repair, or who had Down's syndrome had a less predictable cost picture than patients undergoing ventricular septal defect repair who were older than 2 years, who had short (< 4 days) preoperative hospitalization, or who did not have Down's syndrome ($48,252 +/- $42,539 versus $15,819 +/- $7,219; p = 0.008). Patients with atrioventricular canals who had long preoperative hospitalization (> 7 days), usually due to pneumonia (respiratory syncytial virus) with preoperative mechanical ventilation had significantly higher cost than patients with atrioventricular canals who underwent elective repair with short preoperative hospitalization ($83,324 +/- $60,138 versus $26,904 +/- $5,384; p = 0.05). Patients with tetralogy of Fallot had higher costs if they had multiple congenital anomalies, previous palliation (combining costs of both surgical procedures and hospital stays), or severe "tet" spells at the time of presentation for operation compared with patients without these risk factors ($114,202 +/- $88,524 versus $22,241 +/- $7,071; p = 0.0005). One patient (with tetralogy of Fallot) with multiple congenital anomalies died 42 days after tetralogy of Fallot repair of sepsis after a gastrointestinal operation. Otherwise, hospital mortality was 0% for all groups. CONCLUSIONS: Low mortality and good long-term outcome for surgical correction of congenital heart defects is now commonplace, but can be expensive as some patients with complex problems receive the care necessary to survive. This study demonstrates that it is possible to identify factors preoperatively that predict financial risk. This knowledge may facilitate implementation of risk adjustments for managed care contracting and for strategic resource allocation.     

Research without billing data. Econometric estimation of patient-specific costs

OBJECTIVES: This article describes a method for computing the cost of care provided to individual patients in health care systems that do not routinely generate billing data, but gather information on patient utilization and total facility costs. METHODS: Aggregate data on cost and utilization were used to estimate how costs vary with characteristics of patients and facilities of the US Department of Veterans Affairs. A set of cost functions was estimated, taking advantage of the department-level organization of the data. Casemix measures were used to determine the costs of acute hospital and long-term care. RESULTS: Hospitalization for medical conditions cost an average of $5,642 per US Health Care Financing Administration diagnosis-related group weight; surgical hospitalizations cost $11,836. Nursing home care cost $197.33 per day, intermediate care cost $280.66 per day, psychiatric care cost $307.33 per day, and domiciliary care cost $111.84 per day. Outpatient visits cost an average of $90.36. These estimates include the cost of physician services. CONCLUSIONS: The econometric method presented here accounts for variation in resource use caused by casemix that is not reflected in length of stay and for the effects of medical education, research, facility size, and wage rates. Data on non-Veteran's Affairs hospital stays suggest that the method accounts for 40% of the variation in acute hospital care costs and is superior to cost estimates based on length of stay or diagnosis-related group weight alone.     

Differential subcellular localization of the survival motor neuron protein in spinal cord and skeletal muscle

OBJECTIVE: To determine the outcome, safety, and possible cost savings of patients undergoing weekend or holiday exercise treadmill testing. DESIGN: Medical records of all 195 patients scheduled for weekend and holiday exercise testing were reviewed, and 77.9% of patients were contacted by telephone to ascertain medical outcomes and need for further emergency department or inpatient care. Costs were calculated from estimates of days of hospitalization saved and incremental costs incurred in conjunction with weekend or holiday testing. SETTING: Urban tertiary care academic medical center. PATIENTS: A total of 195 patients were scheduled for testing, and 181 tests were performed. Over three quarters (75.1%) of patients underwent testing for assessment of chest pain. Other indications included risk stratification after myocardial infarction or coronary angioplasty or prior to noncardiac surgery, or evaluation for arrhythmias, dyspnea, or syncope. MEASUREMENTS AND MAIN RESULTS: Outcomes included results and complications of testing, hospital course after testing, subsequent emergency department visits and readmissions, myocardial infarction, need for cardiac catheterization or revascularization, and mortality. No complications were noted during testing. In 136 patients tested for the indication of chest pain, 90 (66.2%) had negative tests, 39 (28. 7%) were intermediate, and 6 (4.4%) were positive for ischemia. Same day discharge occurred in 115 (84.6%) of the patients, saving an estimated 185 days of hospitalization ($316.83 per patient tested). Event rates over the 6 months following discharge were low. CONCLUSIONS: Weekend and holiday exercise testing is a safe and effective means of risk stratification prior to hospital discharge for patients with chest pain. It also reduces length of stay and is cost saving.     

Profile and cost of head injury patients admitted to the Waikato Hospital Intensive Care Unit

AIMS: To examine the profile and hospital costs of head injury patients admitted to the Waikato Hospital Intensive Care Unit (ICU). METHODS: Data were collected on head injury patients admitted to ICU over 41 months and costs of head injury patients in ICU, the High Dependency Unit (HDU) and other wards were calculated. RESULTS: There were 286 head injury patients admitted to ICU, of whom 62% had a Glasgow Coma Score < or = 8. Times in the ICU and hospital were 1760 and 7352 days respectively. Costs per day were $2280 in ICU, $800 in HDU and $500 in other wards. The cost for ICU was $1,174,478 per year, and for the total hospital treatment, $2.05 million (83 head injury patients) per year. Admissions of head injury patients to all New Zealand ICUs were 777 over the year to June 1996. Thus, assuming similar costs to the Waikato Hospital, New Zealand hospitals spend each year approximately 10.9 million dollars on head injury patients in ICUs and 19 million dollars on overall hospital stays (including ICU). In a selected group of 123 severe head injury patients, the six month Glasgow Outcome Scores showed that 36% were in the moderate to severe disability categories and likely to cause major ongoing ACC costs. The costs of the 80% of head injury patients admitted to hospital but not admitted to ICU, and their prehospital and postdischarge costs were not studied. CONCLUSIONS: The New Zealand epidemic of head injuries continues to consume large amounts of the health money and produce major social costs.     

Pronounced differences between the native K+ channels and KAT1 and KST1 alpha-subunit homomers of guard cells

BACKGROUND: Stroke occurs concurrently with myocardial infarction (MI) in approximately 30 000 US patients each year. This number is expected to rise with the increasing use of thrombolytic therapy for MI. However, no data exist for the economic effect of stroke in the setting of acute MI (AMI). The purpose of this prospective study was to assess the effect of stroke on medical resource use and costs in AMI patients in the United States. METHODS AND RESULTS: Medical resource use and cost data were prospectively collected for 2566 randomly selected US GUSTO I patients (from 23 105 patients) and for the 321 US GUSTO I patients who developed non-bypass surgery-related stroke during the baseline hospitalization. Follow-up was for 1 year. All costs are expressed in 1993 US dollars. During the baseline hospitalization, stroke was associated with a reduction in cardiac procedure rates and an increase in length of stay, despite a hospital mortality rate of 37%. Together with stroke-related procedural costs of $2220 per patient, the baseline medical costs increased by 44% ($29 242 versus $20 301, P<0.0001). Follow-up medical costs were substantially higher for stroke survivors ($22 400 versus $5282, P<0.0001), dominated by the cost of institutional care. The main determinant for institutional care was discharge disability status. The cumulative 1-year medical costs for stroke patients were $15 092 higher than for no-stroke patients. Hemorrhagic stroke patients had a much higher hospital mortality rate than non-hemorrhagic stroke patients (53% versus 15%, P<0.001), which was associated with approximately $7200 lower mean baseline hospitalization cost. At discharge, hemorrhagic stroke patients were more likely to be disabled (68% versus 46%, P=0.002). CONCLUSIONS: In this first large prospective economic study of stroke in AMI patients, we found that strokes were associated with a 60% ($15 092) increase in cumulative 1-year medical costs. Baseline hospitalization costs were 44% higher because of longer mean lengths of stay. Stroke type was a key determinant of baseline cost. Follow-up costs were more than quadrupled for stroke survivors because of the need for institutional care. Disability level was the main determinant of institutional care and thus of follow-up costs.     

Ambulatory care visits to physician offices, hospital outpatient departments, and emergency departments: United States, 1996

OBJECTIVE: This report describes ambulatory care visits in the United States across three ambulatory care settings--physician offices, hospital outpatient departments, and hospital emergency departments. Statistics are presented on selected patient and visit characteristics for all ambulatory care visits and separately for each setting. METHODS: The data presented in this report were collected by means of the 1996 National Ambulatory Medical Care Survey (NAMCS) and the 1996 National Hospital Ambulatory Medical Care Survey (NHAMCS). These surveys are part of the ambulatory care component of the National Health Care Survey that measures health care utilization across a variety of providers. The NAMCS and NHAMCS are national probability sample surveys of visits to office-based physicians (NAMCS) and visits to the outpatient departments and emergency departments of non-Federal, short-stay and general hospitals (NHAMCS) in the United States. Sample data are weighted to produce annual estimates. RESULTS: During 1996 an estimated 892 million visits were made to physician offices, hospital outpatient departments, and hospital emergency departments in the United States, an overall rate of 3.4 visits per person. Visits to office-based physicians accounted for 82.3 percent of ambulatory care utilization, followed by visits to emergency departments (10.1 percent) and outpatient departments (7.5 percent). Persons 75 years and over had the highest rate of ambulatory care visits. Females had significantly higher rates of visits to physician offices and hospital outpatient departments than males did. About two-thirds of ambulatory care visits by black persons were to physician offices. There were an estimated 129.3 million injury-related ambulatory care visits during 1996 or 48.9 visits per 100 persons.     

An assessment of the early management of spine problems and appropriateness of diagnostic imaging utilization

Low back pain may affect up to 80% of all adults and is the second leading reason for physician visits in ambulatory medicine. Estimates for the annual direct medical costs for treating patients with back pain approach $25 million, despite the fact that it is a self-limited condition in at least 90% of patients with recovery occurring within 6 to 12 weeks. Recent scrutiny of health care delivery has produced numerous observations documenting a high variability in use of resources for medical conditions including low back pain, but few studies have attempted to examine the medical appropriateness of diagnostic and therapeutic decisions.     

Ambulatory visits to hospital emergency departments. Patterns and reasons for use. 24 Hours in the ED Study Group

OBJECTIVES: To characterize the reasons ambulatory patients use hospital emergency departments (EDs) for outpatient care and to determine the proportion of ED patients who initially are assessed as having nonurgent conditions, but subsequently are hospitalized. DESIGN: Cross-sectional survey during a single 24-hour period of time. SETTING: Fifty-six hospital EDs nationwide. PATIENTS OR OTHER PARTICIPANTS: Consecutive ambulatory patients presenting for care. Patents who arrived by ambulance were excluded. RESULTS: Of 6441 ambulatory patients (79 percent of all ED visits) who were eligible for study, interviews were obtained from 6187 (96 percent). A total of 5323 patients (86 percent) had clinical reasons or preferences for seeking care at an ED, including 2799 (45 percent) who thought they had an emergency or an urgent condition or were too sick to go elsewhere. Nineteen percent (n=1199) reported that they were sent to the ED by a health care professional. Patients with a regular clinician or with insurance cited similar reasons for seeking care at an ED. A total of 3062 patients (50 percent) cited 1 or more nonfinancial barriers to care as an important reason for coming to the ED, and 949 (15 percent) cited financial considerations. A total of 3045 patents (49 percent of ambulatory patients and 37 percent of total ED visits) were assessed at triage as having a nonurgent condition; 166 of them (5.5 percent; 95 percent confidence interval, 4.7 percent-6.3 percent) were admitted to the hospital. CONCLUSIONS: Most ambulatory patients seek care in an ED because of worrisome symptoms or nonfinancial barriers to care. Although many ambulatory patients appear to have nonurgent conditions based on triage classification, a small but disturbing percentage of nonurgent patients are hospitalized.     

Tyrosine kinase: implications in tumor pathology and therapeutic perspectives

PURPOSE: Both generalist and pulmonologist physicians care for patients with severe chronic obstructive pulmonary disease (COPD). We studied patients hospitalized with severe COPD to explore whether supervision of care by pulmonologists is associated with greater costs or better survival. SUBJECTS AND METHODS: We studied 866 adults with severe COPD enrolled in the Study to Understand Prognoses and Preferences for Outcomes and Risks of Treatments (SUPPORT), a prospective study at five academic medical centers. Patients were admitted to the hospital or transferred to an intensive care setting for treatment of severe COPD, defined by hypoxia (PaO2 <60 mm Hg) and hypercapnia (PaCO2 >50 mm Hg) or hypercapnia alone if on supplemental oxygen. Resource intensity was measured using a modified version of the Therapeutic Intervention Scoring System and estimated hospital costs. To account for differences in the patient case mix, propensity scores were developed to represent each patient's probability of having a pulmonologist as attending physician and each patient's probability of being in an intensive care unit (ICU) at study admission. RESULTS: Of the 866 patients studied, 512 had generalists and 354 pulmonologists as their attending physicians. The median patient age was 70 years; 52% were male; 14% died within 30 days. After adjusting for baseline differences in patient characteristics, there were no differences in resource intensity and hospital costs in those treated by pulmonologists or generalists. Adjusted average resource intensity scores for the entire hospitalization were 16.5 for pulmonologists and 17.0 for generalists (P = 0.34). Estimated hospital costs were the same ($6,400) for patients treated by pulmonologists and generalists (P = 0.99). Patients with pulmonologists as attending physicians did not experience better survival. Comparing patients of pulmonologists to patients of generalists, the adjusted hazard ratio for 30-day mortality was 1.6 (95% confidence interval: 0.98, 2.5); the hazard ratio for 180-day mortality was 1.2 (0.9, 1.7). CONCLUSIONS: Our findings suggest that for patients hospitalized with exacerbation of severe COPD, those with pulmonologist attending physicians do not have higher hospital resource use or better survival than those with generalist attending physicians.     

The effect of strength and endurance training on gait, balance, fall risk, and health services use in community-living older adults

BACKGROUND: The study tested the effect of strength and endurance training on gait, balance, physical health status, fall risk, and health services use in older adults. METHODS: The study was a single-blinded, randomized controlled trial with intention-to-treat analysis. Adults (n = 105) age 68-85 with at least mild deficits in strength and balance were selected from a random sample of enrollees in a health maintenance organization. The intervention was supervised exercise (1-h sessions, three per week, for 24-26 weeks), followed by self-supervised exercise. Exercise groups included strength training using weight machines (n = 25), endurance training using bicycles (n = 25), and strength and endurance training (n = 25). Study outcomes included gait tests, balance tests, physical health status measures, self-reported falls (up to 25 months of follow-up), and inpatient and outpatient use and costs. RESULTS: There were no effects of exercise on gait, balance, or physical health status. Exercise had a protective effect on risk of falling (relative hazard = .53, 95% CI = .30-.91). Between 7 and 18 months after randomization, control subjects had more outpatient clinic visits (p < .06) and were more likely to sustain hospital costs over $5000 (p < .05). CONCLUSIONS: Exercise may have beneficial effects on fall rates and health care use in some subgroups of older adults. In community-living adults with mainly mild impairments in gait, balance, and physical health status, short-term exercise may not have a restorative effect on these impairments.     

Basaloid squamous cell carcinoma: a distinctive human papilloma virus-related penile neoplasm: a report of 20 cases

OBJECTIVE: To estimate the costs and benefits to community pharmacies of converting a traditional practice into one based on pharmaceutical care. SETTING: Community-based ambulatory care pharmacies. PRACTICE DESCRIPTION: Community pharmacy. PRACTICE INNOVATION: Pharmaceutical care. MAIN OUTCOME MEASURES: Costs incurred and revenues received. DESIGN: Twenty-five community pharmacies that had made the transition from traditional practice to one based on pharmaceutical care returned a survey providing data on the costs and revenues associated with the transition. RESULTS: Mean total cost of making the conversion for the 25 pharmacies was $36,207. The largest cost component associated with the transition was personnel, which had a mean cost of $16,512 per pharmacy. Mean revenues received for pharmaceutical care by these 25 pharmacies was $3,687, mainly for disease management services. Pharmacies that spent more on the conversions, and used brochures and physician detailing as well as consultants and franschises, tended to be more successful in generating revenues from pharmaceutical care. CONCLUSION: Most pharmacies that have made the conversion to pharmaceutical care have not experienced an increase in profits as a result of that conversion. More effort needs to be directed toward improving the flow of revenues obtained from providing pharmaceutical care.     

Plasma levels of activated protein C in healthy subjects and patients with previous venous thromboembolism: relationships with plasma homocysteine levels

BACKGROUND/PURPOSE: In the pediatric population, appendicitis remains the most common surgical emergency encountered. The purpose of this study was to determine the impact of an evidence-based clinical pathway for acute appendicitis on patient care as well as hospital and home care costs at the authors' pediatric institution. METHODS: A prospective evaluation was conducted of an appendicitis clinical pathway (June 1996 through November 1996) compared with historical control patients (June 1994 through November 1994) not cared for by the pathway. RESULTS: Data (average +/- SD) for 120 pathway (P) patients were compared with 122 control (C) patients. Age (11.5 +/- 3.6 years for C v 11.2 +/- 3.9 years for P), rates of negative appendectomy (12.3% for C v 9.2% for P) and perforation (26.2% for C v 18.3% for P) were similar. Pathway patients with nonperforated appendicitis were more often discharged from the hospital within 24 hours (48% for C v 67% for P; P = .014) with lower hospital costs ($4,095 +/- $1,280 for C v $3,638 +/- $1,633 for P; P = .001). Pathway patients with perforated appendicitis had shorter hospitalization (185.2 +/- 59 hours for C v 113 +/- 44 hours for P; P = .0001) and lower hospital costs ($11,175 +/- $3,893 for C v $7,823 +/- $2,366 for P; P = .0001). CONCLUSION: An evidence-based appendicitis pathway decreased duration of hospitalization and cost without adversely affecting diagnosis or therapy. Clinical pathways for surgical diagnoses may prove useful as a means to minimize costs without compromising patient care.     

Predictors of mortality in the prospective Dubbo study of Australian elderly

BACKGROUND: A study was undertaken to examine the relationship between first-contact care, an essential feature of primary care, and expenditures for frequent ambulatory episodes of care in a nationally representative sample. METHODS: A nonconcurrent cohort study was conducted using data from the 1987 National Medical Expenditure Survey. Ambulatory claims data of respondents with an identified primary care source were used to develop 20,282 episodes of care for 24 preventive and acute illness conditions. The study examined the relationship of first-contact care, defined as the use of an identified primary care source for the first visit in an episode, and ambulatory episode-of-care expenditures. RESULTS: Episodes that began with visits to an individual's primary care clinician, as opposed to other sources of care, were associated with reductions in expenditures of 53% overall ($63 vs 134, P<.001), 62% for acute illnesses ($62 vs $164, P<.001), and 20 for preventive care ($64 vs $80, P<.001). For 23 of the 24 health problems studied, first-contact care was associated with reductions in expenditures. Multivariate regression analyses that controlled for sociodemographic characteristics, health status, case-mix, length of the episode, and number of visits to the emergency room did not substantively alter these results. CONCLUSIONS: First-contact care was associated with reductions in ambulatory episode-of-care expenditures of over 50% in a nationally representative sample. These findings suggest that systems of care may reduce ambulatory expenditures.
