Measuring the effects of work loss on productivity with team production.

Using data from a survey of 800 managers in 12 industries, we find empirical support for the hypothesis that the cost associated with missed work varies across jobs according to the ease with which a manager can find a perfect replacement for the absent worker, the extent to which the worker functions as part of a team, and the time sensitivity of the worker's output. We then estimate wage 'multipliers' for 35 different jobs, where the multiplier is defined as the cost to the firm of an absence as a proportion (often greater than one) of the absent worker's daily wage. The median multiplier is 1.28, which supports the view that the cost to the firm of missed work is often greater than the wage.

Self-medication and health insurance coverage in Mexico.

Self-medication is a common practice in many developing countries but little is known about its determinants. This study analyzes the factors that are associated with the use of self-medication in Mexico using the Mexican Health and Aging Study, a new nationally representative survey on adults aged 50 and over. We find that self-medication is related to socioeconomic status and the lack of access to professional healthcare. Our empirical results suggest that lack of government-sponsored health insurance coverage increases the propensity to self-medicate. A 10% increase in the proportion of adults with health insurance coverage could decrease the use of pharmacy consultations by .8% for public sector workers and by 1.7% for private sector workers. Increasing health insurance coverage could reduce the demand for self-medication by making healthcare more affordable and by changing the population perceptions about the benefits of modern medicine.

17alpha-hydroxyprogesterone caproate for the prevention of preterm delivery: A cost-effectiveness analysis.

OBJECTIVE: To evaluate whether the use of 17alpha-hydroxyprogesterone caproate for the prevention of recurrent preterm deliveries is cost-effective. METHODS: Using decision-analysis modeling, we compared the cost-effectiveness of using 17alpha-hydroxyprogesterone caproate in four subgroups: 1) Prior preterm deliveries less than 32 weeks; 2) prior preterm deliveries 32-37 weeks; 3) prior term delivery; and 4) no prior delivery. Each subgroup was compared with a "no treatment" group. Costs included those for 17alpha-hydroxyprogesterone caproate, hospital admissions, and complications from preterm deliveries. The main outcome measures include cost per quality-adjusted life-year gained and the number of preterm deliveries prevented. Secondary outcomes include neonatal complications prevented. One-way and multiway sensitivity analyses were performed. RESULTS: The use of 17alpha-hydroxyprogesterone caproate for the prevention of preterm deliveries result in cost-savings in women with prior preterm deliveries less than 32 weeks and 32-37 weeks. The sensitivity analyses revealed the model to be robust over a wide range of values for evaluated variables. CONCLUSION: Within our baseline assumptions, 17alpha-hydroxyprogesterone caproate was associated with cost-savings when used for the prevention of preterm deliveries in women with prior preterm deliveries.

Variation in chemotherapy utilization in ovarian cancer: the relative contribution of geography.

OBJECTIVE: This study investigates geographic variation in chemotherapy utilization for ovarian cancer in both absolute and relative terms and examines area characteristics associated with this variation. DATA SOURCES: Surveillance, Epidemiology, and End Results (SEER) Medicare data from 1990 to 2001 for Medicare patients over 65 with a diagnosis of ovarian cancer between 1990 and 1999. Chemotherapy within a year of diagnosis was identified by Medicare billing codes. The hospital referral region (HRR) represents the geographic unit of analysis. STUDY DESIGN: A logit model predicting the probability of receiving chemotherapy by each of the 39 HRRs. Control variables included medical characteristics (patient age, stage, year of diagnosis, and comorbidities) and socioeconomic characteristics (race, income, and education). The variation among HRRs was tested by the chi2 statistic, and the relative contribution was measured by the omega statistic. HHR market characteristic are then used to explain HRR-level variation. PRINCIPAL FINDINGS: The average chemotherapy rate was 56.6 percent, with a range by HRR from 33 percent to 67 percent. There were large and significant differences in chemotherapy use between HRRs, reflected by a chi2 for HRR of 146 (df = 38, p < .001). HRR-level variation in chemotherapy use can be partially explained by higher chemotherapy rates in HRRs with a higher percentage of hospitals with oncology services. However, an omega analysis indicates that, by about 15 to one, the variation between patients in use of chemotherapy reflects variations in patient characteristics rather than unexplained variation among HRRs. CONCLUSIONS: While absolute levels of chemotherapy variation between geographic areas are large and statistically significant, this analysis suggests that the role of geography in determining who gets chemotherapy is small relative to individual medical characteristics. Nevertheless, while variation by medical characteristics can be medically justified, the same cannot be said for geographic variation. Our finding that density of oncology hospitals predicts chemotherapy use suggests that provider supply is positively correlated with geographic variation.

Clinical trial-based cost-effectiveness analyses of antipsychotic use.

OBJECTIVE: Second-generation antipsychotics make up one of the fastest growing segments of the rapidly growing pharmaceutical sector. Given limited health care resources, assessment of the value for the cost of second-generation antipsychotics relative to first-generation antipsychotics is critical for resource-allocation decisions. METHOD: With a MEDLINE search, the authors identified eight studies (based on six randomized clinical trials) that analyzed the cost-effectiveness of second-generation antipsychotics relative to first-generation antipsychotics in individuals with schizophrenia disorders. The authors reviewed appropriate methods of measurement, analysis, and design of cost-effectiveness studies in randomized clinical trials and evaluated the validity of economic results derived from the studies in light of appropriate methods. RESULTS: The eight randomized clinical trial-based cost-effectiveness studies of antipsychotic medications faced a variety of threats to validity related to 1) measurement of costs, 2) measurement of effectiveness, 3) analysis of costs, 4) measurement of sampling uncertainty, 5) analysis of incomplete cost data, 6) minimizing loss to follow-up, and 7) threats to external validity. CONCLUSIONS: Economic claims made by the authors of a number of trial-based economic evaluations have generally been favorable to second-generation antipsychotics. However, the methodological issues the authors of the current study identified suggest that there is no clear evidence that atypical antipsychotics generate cost savings or are cost-effective in general use among all schizophrenia patients. Psychiatrists, researchers, and administrators should consider the methodological issues highlighted in interpreting study results. These issues should be addressed in future trial designs.

Access to health care for migrants returning to Mexico.

Continued migration from Mexico over the past several decades has created a large population of elderly Mexicans in the U.S. There is no system in Mexico for those Mexicans who would like to retire there to obtain health insurance during their retirement years. Using a nationally representative dataset of Mexican elders, we explore the current state of health insurance status for Mexican elders with a history of migration to the U.S. We find a robust negative association between years spent in the U.S. and the probability of being insured. Coordination between the U.S. and Mexico on policy options to insure Mexicans migrants may prove beneficial to the social security systems in both countries as well as to migrants themselves.

Changes in veterans' use of outpatient care from 1992 to 2000.

OBJECTIVES: During the mid-1990s, the Veterans Health Administration (VHA) reorganized and placed greater emphasis on high-quality primary care. To determine whether the reorganization was associated with changes in patterns of out-patient VHA use, we sought to evaluate changes in characteristics of veterans who use VHA outpatient services between 1992 and 2000. METHODS: We merged 2 waves of the National Survey of Veterans to determine changes in patterns of outpatient care use. We evaluated the extent to which veterans who received outpatient care received that care from the VHA. RESULTS: The odds ratio for VHA-only outpatient care relative to non-VHA-only care in 2000 relative to 1992 was 1.75 (95% confidence interval [CI]=1.51, 2.04), and the odds ratio for dual relative to non-VHA-only care was 1.22 (95% CI=1.08, 1.37). Veterans who were older, had low incomes, and had no additional health insurance coverage were most likely to increase their use of VHA outpatient care. CONCLUSIONS: Our results suggest that the VHA is increasingly serving veterans who have trouble accessing the private health care system.

Long-term risk for depressive symptoms after a medical diagnosis.

BACKGROUND: This study examines the risk of development of significant depressive symptoms after a new diagnosis of cancer, diabetes, hypertension, heart disease, arthritis, chronic lung disease, or stroke. METHODS: The study used 5 biennial waves (1992-2000) of the Health and Retirement Study to follow a sample of 8387 adults (aged 51 to 61 years and without significant depressive symptoms in 1992) from 1994 to 2000. Time-dependent Cox regression models estimated adjusted hazard ratios (HRs) for an episode of significant depressive symptoms after a new diagnosis for each of the 7 medical conditions. RESULTS: Within 2 years of initial diagnosis, subjects with cancer had the highest hazard of depressive symptoms (HR, 3.55; 95% confidence interval [CI], 2.79-4.52), followed by subjects with chronic lung disease (HR, 2.21; 95% CI, 1.64-2.79) and heart disease (HR, 1.45; 95% CI, 1.09-1.93). The hazard for depressive symptoms for most of these diseases decreased over time; however, subjects with heart disease continued to have a higher risk for depressive symptoms even 2 to 4 years and 4 to 8 years after diagnosis, and a significantly higher hazard for depressive symptoms developed for persons with arthritis 2 to 4 years after diagnosis (HR, 1.46; 95% CI, 1.11-1.92). CONCLUSION: The findings identify several high-risk patient groups who might benefit from depression screening and monitoring to improve health outcomes in this vulnerable population facing new medical illnesses.

Racial profiling: the unintended consequences of coronary artery bypass graft report cards.

BACKGROUND: Although public release of quality information through report cards is intended to improve health care, there may be unintended consequences of report cards, such as physicians avoiding high-risk patients to improve their ratings. If physicians believe that racial and ethnic minorities are at higher risk for poor outcomes, report cards could worsen existing racial and ethnic disparities in health care. METHODS AND RESULTS: To investigate the impact of New York's CABG report card on racial and ethnic disparities in cardiac care, we estimated differences in the use of CABG, PTCA, and cardiac catheterization between white versus black and Hispanic patients hospitalized for acute myocardial infarction in New York before and after New York's first CABG report card was released, adjusting for patient and hospital characteristics and national changes in racial and ethnic disparities in cardiac care. The racial and ethnic disparity in CABG use significantly increased in New York immediately after New York's CABG report card was released, whereas disparities did not change significantly in the comparison states. There was no differential change in racial and ethnic disparities between New York and the comparison states in the use of cardiac catheterization or PTCA after the CABG report card was released. Over time, this increase in racial and ethnic disparities decreased to levels similar to those before the release of report cards. CONCLUSIONS: The release of CABG report cards in New York was associated with a widening of the disparity in CABG use between white versus black and Hispanic patients.

Comparing the supply of pediatric subspecialists and child neurologists.

OBJECTIVE: To examine physician workforce characteristics and workforce projections of one vulnerable pediatric subspecialty, child neurology, and compare this subspecialty with other pediatric subspecialties, general pediatrics, and adult neurology. STUDY DESIGN: National survey of child neurologists compared with other pediatric specialties in the Community Tracking Study Physician Survey (CTS) and the American Medical Association (AMA) Masterfile, and input-output workforce projections. RESULTS: Child neurologists are more likely than other specialists to report that the complexity or severity of patients' conditions at the time of referral is less than it should be and that the number of patients being referred to them has increased. Projections of the future workforce reveal that by 2022 the number of pediatric subspecialists and pediatricians will increase substantially, to almost 180% and 150% of the current workforce, respectively. Among child neurologists and adult neurologists, practicing physicians will be only 109% and 105% of the current workforce by 2022. CONCLUSIONS: Child neurologists are more likely to face future workforce shortages than other pediatric subspecialists. To reduce future shortages, recruitment efforts need to be concentrated on the at-risk subspecialties such as child neurology. In the short-term, addressing the high prevalence of inappropriate low-acuity referrals to child neurologists may ease the gap between supply and demand.

Employer health insurance offerings and employee enrollment decisions.

OBJECTIVE: To determine how the characteristics of the health benefits offered by employers affect worker insurance coverage decisions. DATA SOURCES: The 1996-1997 and the 1998-1999 rounds of the nationally representative Community Tracking Study Household Survey. STUDY DESIGN: We use multinomial logistic regression to analyze the choice between own-employer coverage, alternative source coverage, and no coverage among employees offered health insurance by their employer. The key explanatory variables are the types of health plans offered and the net premium offered. The models include controls for personal, health plan, and job characteristics. PRINCIPAL FINDINGS: When an employer offers only a health maintenance organization married employees are more likely to decline coverage from their employer and take-up another offer (odds ratio (OR)=1.27, p<.001), while singles are more likely to accept the coverage offered by their employer and less likely to be uninsured (OR=0.650, p<.001). Higher net premiums increase the odds of declining the coverage offered by an employer and remaining uninsured for both married (OR=1.023, p<.01) and single (OR=1.035, p<.001) workers. CONCLUSIONS: The type of health plan coverage an employer offers affects whether its employees take-up insurance, but has a smaller effect on overall coverage rates for workers and their families because of the availability of alternative sources of coverage. Relative to offering only a non-HMO plan, employers offering only an HMO may reduce take-up among those with alternative sources of coverage, but increase take-up among those who would otherwise go uninsured. By modeling the possibility of take-up through the health insurance offers from the employer of the spouse, the decline in coverage rates from higher net premiums is less than previous estimates.

How to present the business case for healthcare quality to employers.

Many employers in the US are investing in new programmes to improve the quality of medical care and simultaneously shifting more of the healthcare costs to their employees without understanding the implications on the amount and type of care their employees will receive. These seemingly contradictory actions reflect an inability by employers to accurately assess how their health benefit decisions affect their profits. This paper proposes a practical method that employers can use to determine how much they should invest in the health of their workers and to identify the best benefit designs to encourage appropriate healthcare delivery and use. This method could also be of value to employers in other countries who are considering implementing programmes to improve employee health. The method allows a programme that improves workers' health to generate four financial benefits for an employer - reduced medical costs, reduced absences, improved on-the-job productivity, and reduced turnover - and uses accurate estimates of the benefits of reducing absences and improving productivity.

Child neurology: workforce and practice characteristics.

For more than a decade, reports have indicated that the supply of child neurologists is inadequate to provide care for the growing number of children with acquired and genetic neurological conditions. It is critical to understand how the shortages affect the practice of child neurology, the attitudes of child neurologists, and ability of the field to attract new members. This Issue Brief examines these workforce issues, and profiles the attitudes and practice characteristics of child neurologists and trainees.

Morbidity and mortality of colorectal carcinoma surgery differs by insurance status.

BACKGROUND: Uninsured and underinsured patients are reported to be at an increased risk for impaired access to healthcare, delayed medical treatment, and the receipt of substandard care. These differences in care may result in disparities in surgical outcomes among patients with different types of insurance. In the current study, the authors examined associations between the insurance provider and short-term surgical outcomes after surgery for colorectal carcinoma and evaluated the extent to which two risk factors (comorbid disease and admission type) might explain any observed association. METHODS: The authors conducted a nationally representative retrospective cohort study of 13,415 adults ages 40-64 years who were admitted for surgery for colorectal carcinoma to hospitals that participated in the Agency for Healthcare Research and Quality Healthcare Cost and Utilization Project National Inpatient Sample, releases 6 and 7, in 1997 and 1998. Multivariate logistic regression models were developed to describe the correlations between insurance status and the risks of a postoperative complication or postoperative death after adjustment for socioeconomic factors, comorbid conditions, and admission type. RESULTS: Uninsured and Medicaid patients were found to have more emergent admissions and more comorbid disease compared with patients with private health insurance. Patients without private health insurance had higher rates of postoperative complications and in-hospital death compared with those patients with private insurance. After adjusting for patient and hospital characteristics, patients with Medicaid were found to be 22% more likely to develop a complication during their hospital admission (odds ratio [OR] of 1.22; 95% confidence interval [95%CI], 1.06-1.40) and 57% more likely to die postoperatively (OR of 1.57; 95% CI, 1.01-2.42) compared with patients with private insurance. CONCLUSIONS: The current study findings suggest that the uninsured and Medicaid populations are at greater risk of developing postoperative complications and dying than the privately insured population due only in part to preexisting medical comorbidities and emergent admission type.

Strategies to attract medical students to the specialty of child neurology.

The decline in the number of medical students choosing to enter the field of child neurology is a concern. We undertook this study to learn more about the qualities of highly regarded medical schools that may play a role in attracting students to the field of child neurology. We surveyed child neurologists at top U.S. medical schools that were most successful and least successful at attracting students to child neurology to determine what factors influenced the number of students entering the field of child neurology. We determined that the medical schools that produced the most child neurologists had stronger neuroscience curricula, stronger academic reputations, and larger Divisions of Child Neurology. Our findings suggest that our attention should be focused on academic centers that have more resources to create an atmosphere that is appealing to prospective applicants. These schools should implement a curriculum in neuroscience and child neurology that specifically exposes students early and maintains their interest in the field of child neurology.

The 2004 Marshall Urist award: delays until surgery after hip fracture increases mortality.

The objective of this study was to analyze whether a delay in time from admission until surgical treatment increased the mortality rate for patients with a closed hip fracture. We used the day of the week of admission as an instrumental variable to pseudorandomize patients. We analyzed 18,209 Medicare recipients who were 65 years of age or older and had surgical treatment for a closed hip fracture. Patients for whom the delay between admission and surgery was 2 days or more had a 17% higher chance of dying by Day 30. Using instrumental variables analysis, we found a similar 15% increased risk of mortality in patients with delays until surgery of 2 or more days. Based on these results, we found that a delay of 2 or more days significantly increased the mortality rate. This suggests that delay to surgery independently affects mortality, therefore additional study on the effect of smaller delays on outcome is needed.
