Discharge to post-acute care and other predictors of prolonged length of stay during the initial COVID-19 surge: a single site analysis.

BACKGROUND: During the initial surge of coronavirus disease 2019 (COVID-19), health-care utilization fluctuated dramatically, straining acute hospital capacity across the USA and potentially contributing to excess mortality. METHODS: This was an observational retrospective study of patients with COVID-19 admitted to a large US urban academic medical center during a 12-week COVID-19 surge in the Spring of 2020. We describe patterns in length of stay (LOS) over time. Our outcome of interest was prolonged LOS (PLOS), which we defined as 7 or more days. We performed univariate analyses of patient characteristics, clinical outcomes and discharge disposition to evaluate the association of each variable with PLOS and developed a final multivariate model via backward elimination, wherein all variables with a P-value above 0.05 were eliminated in a stepwise fashion. RESULTS: The cohort included 1366 patients, of whom 13% died and 29% were readmitted within 30 days. The LOS (mean: 12.6) fell over time (P < 0.0001). Predictors of PLOS included discharge to a post-acute care (PAC) facility (odds ratio [OR]: 11.9, 95% confidence interval [CI] 2.6-54.0), uninsured status (OR 3.2, CI 1.1-9.1) and requiring intensive care and intubation (OR 18.4, CI 11.5-29.6). Patients had a higher readmission rate if discharged to PAC facilities (40%) or home with home health agency (HHA) services (38%) as compared to patients discharged home without HHA services (26%) (P < 0.0001). CONCLUSION: Patients hospitalized with COVID-19 during a US COVID-19 surge had a PLOS and high readmission rate. Lack of insurance, an intensive care unit stay and a decision to discharge to a PAC facility were associated with a PLOS. Efforts to decrease LOS and optimize hospital capacity during COVID-19 surges may benefit from focusing on increasing PAC and HHA capacity and resources.

Statin exposure is associated with decreased asthma-related emergency department visits and oral corticosteroid use.

RATIONALE: Statins, or HMG-CoA reductase inhibitors, may aid in the treatment of asthma through their pleiotropic antiinflammatory effects. OBJECTIVES: To examine the effect of statin therapy on asthma-related exacerbations using a large population-based cohort. METHODS: Statin users aged 31 years or greater with asthma were identified from the Population-Based Effectiveness in Asthma and Lung population, which includes data from five health plans. Statin exposure and asthma exacerbations were assessed over a 24-month observation period. Statin users with a statin medication possession ratio greater than or equal to 80% were matched to non-statin users by age, baseline asthma therapy, site of enrollment, season at baseline, and propensity score, which was calculated based on patient demographics and Deyo-Charlson conditions. Asthma exacerbations were defined as two or more oral corticosteroid dispensings, asthma-related emergency department visits, or asthma-related hospitalizations. The association between statin exposure and each of the three outcome measures was assessed using conditional logistic regression. MEASUREMENTS AND MAIN RESULTS: Of the 14,566 statin users, 8,349 statin users were matched to a nonuser. After adjusting for Deyo-Charlson conditions that remained unbalanced after matching, among statin users, statin exposure was associated with decreased odds of having asthma-related emergency department visits (odds ratio [OR], 0.64; 95% confidence interval [CI], 0.53-0.77; P < 0.0001) and two or more oral corticosteroid dispensings (OR, 0.90; 95% CI, 0.81-0.99; P = 0.04). There were no differences in asthma-related hospitalizations (OR, 0.91; 95% CI, 0.66-1.24; P = 0.52). CONCLUSIONS: Among statin users with asthma, statin exposure was associated with decreased odds of asthma-related emergency department visits and oral corticosteroid dispensings.

Valuing health across the lifespan: health state preferences for seasonal influenza illnesses in patients of different ages.

OBJECTIVE: This study sought to measure whether public values for health states vary with the age of the affected individual. METHODS: Health state preferences were measured via a 15-minute survey administered through the Internet in December 2007 using a probability sample of the adult population of the United States (N = 1012). Respondents were asked to value hypothetical descriptions of seasonal influenza illness (uncomplicated influenza illness, hospitalization) and possible vaccine-related adverse events (anaphylaxis, Guillain-Barré syndrome) using time trade-off or willingness-to-pay questions. Respondents were randomized to four different ages for an affected hypothetical individual: 1-year-old, 8-year-old, 35-year-old, 85-year-old. All other aspects of the health state description were held constant. Summary statistics for each health state and age were calculated. The Kruskal-Wallis test was used to measure differences in responses across ages of affected individuals in the hypothetical scenarios. Regression analyses were used to evaluate the effect of age on time trade-off or willingness-to-pay amounts controlling for respondent characteristics. RESULTS: Median values for time trade-off and willingness-to-pay were highest for young children. This pattern was generally consistent across responses and type of valuation. CONCLUSIONS: Approaches that assume health state values do not differ with the age of a patient may bias economic analyses that use these values. If patient age is likely to affect health state valuations, then age should be included as an attribute in the valuation exercise.

Financial barriers to implementing combination vaccines: perspectives from pediatricians and policy makers.

To describe the factors that affect the use of new combination vaccines, the authors conducted qualitative interviews with pediatricians (n = 7), state immunization program managers (n = 7), and health insurance plan representatives (n = 6 plans). Respondents from each group identified reduction in pain and potentially increased immunization coverage as key benefits of new combination vaccines. For several pediatricians, low reimbursement for cost of vaccine doses and potential loss of fees for vaccine administration were barriers to using combination vaccines. For most state immunization programs, the higher cost of combination vaccines relative to separate vaccines was an important consideration but not a barrier to adoption. Most insurers were not aware of the financial issues for providers, but some had changed or were willing to change reimbursement to support the use of new combination vaccines. Financial issues for pediatric practices that purchase and provide vaccines for children may be an important barrier to offering combination vaccines.

Community and patient values for preventing herpes zoster.

OBJECTIVES: The US Advisory Committee on Immunization Practices has recently recommended a new vaccine against herpes zoster (shingles) for routine use in adults aged > or =60 years. However, estimates of the cost effectiveness of this vaccine vary widely, in part because of gaps in the data on the value of preventing herpes zoster. Our aims were to (i) generate comprehensive information on the value of preventing a range of outcomes of herpes zoster; (ii) compare these values among community members and patients with shingles and post-herpetic neuralgia (PHN); and (iii) identify clinical and demographic characteristics that explain the variation in these values. METHODS: Community members drawn from a nationally representative survey research panel (n = 527) completed an Internet-based survey using time trade-off and willingness-to-pay questions to value a series of scenarios that described cases of herpes zoster with varying pain intensities (on a scale of 0 to 10, where 0 represents no pain and 10 represents the worst imaginable pain) and duration (30 days to 1 year). Patients with shingles (n = 382) or PHN (n = 137) [defined as having symptoms for > or =90 days] from two large healthcare systems completed telephone interviews with similar questions to the Internet-based survey and also answered questions about their current experience with herpes zoster. We constructed generalized linear mixed models to evaluate the associations between demographic and clinical characteristics, the length and intensity of the health states and time trade-off and willingness-to-pay values. RESULTS: In time trade-off questions, community members offered a mean of 89 (95% CI 24, 182) discounted days to avoid the least severe scenario (pain level of 3 for 1 month) and a mean of 162 (95% CI 88, 259) discounted days to avoid the most severe scenario (pain level of 8 for 12 months). Compared with patients with shingles, community members traded more days to avoid low-severity scenarios but similar numbers of days to avoid high-severity scenarios. Compared with patients with PHN, community members traded fewer days to avoid high-severity scenarios. In multivariate analyses, older age was the only characteristic significantly associated with higher time trade-off values. In willingness-to-pay questions, community members offered a mean of $US450 (95% CI 203, 893) to avoid pain of level 3 for 1 month and a mean of $US1384 (95% CI 873, 2050) [year 2005 values] to avoid pain of level 8 for 12 months. Community members traded less money than patients with either shingles or PHN to avoid both low- and high-severity scenarios (p-values <0.05 to <0.001). In multivariate models, male gender, higher income and having experienced shingles or PHN were associated with higher willingness to pay to avoid herpes zoster. When patients were asked to assign a value to avoiding their own case of herpes zoster, those with shingles assigned a mean of 67 days or $US2319, while those with PHN assigned a mean of 206 days or $US18 184. Both the time and monetary value traded were associated with the maximum intensity of the pain the individual had experienced, but neither was associated with the duration of the pain. CONCLUSIONS: We believe that this study provides the most comprehensive information to date on the value individuals place on preventing herpes zoster, and it includes the only such valuation from nationally representative community members as well as patients with herpes zoster. Community members would trade substantial amounts of time or money to avoid herpes zoster, even in the least severe scenarios. The time trade-off results in this study may differ from those in other studies because of important differences in methods of assessing health utilities. Consideration of both community and patient perspectives is crucial to help decision makers fully determine the implications of their policies now that a vaccine against herpes zoster is available.

A trial of disclosing physicians' financial incentives to patients.

BACKGROUND: Concern regarding financial conflict of interest for physicians has led to calls for disclosure of financial incentives to patients. However, limited data on the outcomes of disclosure exist to guide policy. METHODS: This randomized trial was conducted among 8000 adult patients at 2 multispecialty group practices based in the Boston, Mass, and Los Angeles, Calif, areas. Intervention patients were mailed a compensation disclosure letter written by the chief medical officer of their physician group, and all patients were surveyed approximately 3 months later. RESULTS: Disclosure patients were significantly more able to identify correctly the compensation model of their primary care physician, in Boston (adjusted odds ratio, 2.30; 95% confidence interval, 1.92-2.75) and in Los Angeles (adjusted odds ratio, 1.37; 95% confidence interval, 1.03-1.82). Disclosure patients also had more confidence in their ability to judge the possible influence of incentives on their health care: in Boston, 32.5% vs 17.8% (P<.001); and in Los Angeles, 31.8% vs 26.4% (P = .20). The disclosure intervention did not change trust in primary care physicians overall. However, of patients who remembered receiving the disclosure, 21.4% in Boston and 24.4% in Los Angeles responded that the disclosure had increased trust either greatly or somewhat, while in both cities less than 5% of patients responded that the information decreased trust. Patients' loyalty to their physician group was higher among disclosure patients in Boston (73.4% vs 70.2%; P = .03) and Los Angeles (74.1% vs 66.9%; P = .08). CONCLUSIONS: Among diverse patient populations, a single mailed disclosure letter from physician groups was associated with improved knowledge of physicians' compensation models. Patients' trust in their physicians was unharmed, and their loyalty to their physician group was strengthened. For physician groups with similar compensation programs, disclosure to patients should be considered an effective method to enhance the patient-physician relationship.

Gaps in vaccine financing for underinsured children in the United States.

CONTEXT: The number of new vaccines recommended for children and adolescents has nearly doubled during the past 5 years, and the cost of fully vaccinating a child has increased dramatically in the past decade. Anecdotal reports from state policy makers and clinicians suggest that new gaps have arisen in financial coverage of vaccines for children who are underinsured (ie, have private insurance that does not cover all recommended vaccines). In 2000, approximately 14% of children were underinsured for vaccines in the United States. OBJECTIVES: To describe variation among states in the provision of new vaccines to underinsured children and to identify barriers to state purchase and distribution of new vaccines. DESIGN, SETTING, AND PARTICIPANTS: A 2-phase mixed-methods study of state immunization program managers in the United States. The first phase included 1-hour qualitative telephone interviews conducted from November to December 2005 with 9 program managers chosen to represent different state vaccine financing policies. The second phase incorporated findings from phase 1 to develop a national telephone and paper-based survey of state immunization program managers that was conducted from January to June 2006. MAIN OUTCOME MEASURES: Percentage of states in which underinsured children are unable to receive publicly purchased vaccines in the private or public sectors. RESULTS: Immunization program managers from 48 states (96%) participated in the study. Underinsured children were not eligible to receive publicly purchased meningococcal conjugate or pneumococcal conjugate vaccines in the private sector in 70% and 50% of states, respectively, or in the public sector in 40% and 17% of states, respectively. Due to limited financing for new vaccines, 10 states changed their policies for provision of publicly purchased vaccines between 2004 and early 2006 to restrict access to selected new vaccines for underinsured children. The most commonly cited barriers to implementation in underinsured children were lack of sufficient federal and state funding to purchase vaccines. CONCLUSIONS: The current vaccine financing system has resulted in gaps for underinsured children in the United States, many of whom are now unable to receive publicly purchased vaccines in either the private or public sectors. Additional strategies are needed to ensure financial coverage for all vaccines, particularly new vaccines, among this vulnerable population.

Psychotropic Medication Use among Insured Children with Autism Spectrum Disorder.

This study examined psychotropic medication use among 7901 children aged 1-17 with autism spectrum disorder (ASD) in five health systems, comparing to matched cohorts with no ASD. Nearly half (48.5 %) of children with ASD received psychotropics in the year observed; the most common classes were stimulants, alpha-agonists, or atomoxetine (30.2 %), antipsychotics (20.5 %), and antidepressants (17.8 %). Psychotropic treatment was far more prevalent among children with ASD, as compared to children with no ASD (7.7 % overall), even within strata defined by the presence or absence of other psychiatric diagnoses. The widespread use of psychotropics we observed, particularly given weak evidence supporting the effectiveness of these medications for most children with ASD, highlights challenges in ASD treatment and the need for greater investment in its evaluation.

Missing clinical and behavioral health data in a large electronic health record (EHR) system.

OBJECTIVE: Recent massive investment in electronic health records (EHRs) was predicated on the assumption of improved patient safety, research capacity, and cost savings. However, most US health systems and health records are fragmented and do not share patient information. Our study compared information available in a typical EHR with more complete data from insurance claims, focusing on diagnoses, visits, and hospital care for depression and bipolar disorder. METHODS: We included insurance plan members aged 12 and over, assigned throughout 2009 to a large multispecialty medical practice in Massachusetts, with diagnoses of depression (N = 5140) or bipolar disorder (N = 462). We extracted insurance claims and EHR data from the primary care site and compared diagnoses of interest, outpatient visits, and acute hospital events (overall and behavioral) between the 2 sources. RESULTS: Patients with depression and bipolar disorder, respectively, averaged 8.4 and 14.0 days of outpatient behavioral care per year; 60% and 54% of these, respectively, were missing from the EHR because they occurred offsite. Total outpatient care days were 20.5 for those with depression and 25.0 for those with bipolar disorder, with 45% and 46% missing, respectively, from the EHR. The EHR missed 89% of acute psychiatric services. Study diagnoses were missing from the EHR's structured event data for 27.3% and 27.7% of patients. CONCLUSION: EHRs inadequately capture mental health diagnoses, visits, specialty care, hospitalizations, and medications. Missing clinical information raises concerns about medical errors and research integrity. Given the fragmentation of health care and poor EHR interoperability, information exchange, and usability, priorities for further investment in health IT will need thoughtful reconsideration.

Use of an electronic medical record to profile the continuity clinic experiences of primary care residents.

PURPOSE: To assess the variation in outpatient educational experiences among residents in a primary care internal medicine residency program. METHOD: The authors conducted an observational study within a primary care residency program in Boston, Massachusetts, involving eight primary care residents in 2001-02. A data management system was created that uses information on clinical experiences collected from an electronic medical record (EMR). The EMR records clinical information from patient encounters in resident continuity clinics, including patient demographics and diagnostic codes entered by the residents. Primary and secondary diagnosis from the International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM) were assigned to clinical categories (e.g., cardiology, orthopedics) and these assignments were programmed into a spreadsheet that could take the diagnostic data directly from the EMR downloads and produce reports using only the primary diagnosis, using all diagnoses, or using the assigned clinical categories. RESULTS: The EMR download showed 2,468 patient encounters for the eight residents in the primary care program. The most common clinical encounters were for health maintenance (17%), cardiology (14%), and women's health (10%). In contrast, rheumatology (0.5%) and hematology/oncology (2%) encounters were less frequent. There were substantial variations among residents in terms of distribution of encounter diagnoses, and the age and gender of patients seen in continuity clinic. CONCLUSIONS: Abstracting data from an EMR represents a feasible method for assessing programmatic and individual learner experiences in the outpatient setting. Such information may help target curricular adjustments to ensure an appropriate diversity and depth of clinical training.

Creating a network of high-quality skilled nursing facilities: preliminary data on the postacute care quality improvement experiences of an accountable care organization.

Postacute care (PAC) is an important source of cost growth and variation in the Medicare program and is critical to accountable care organization (ACO) and bundled payment efforts to improve quality and value in the Medicare program, but ACOs must often look outside their walls to identify high-value external PAC partners, including skilled nursing facilities (SNFs). As a solution to this problem, the integrated health system, Partners HealthCare System (PHS) and its Pioneer ACO launched the PHS SNF Collaborative Network in October 2013 to identify and partner with high-quality SNFs. This study details the method by which PHS selected SNFs using minimum criteria based on public scores and secondary criteria based on self-reported measures, describes the characteristics of selected and nonselected SNFs, and reports SNF satisfaction with the collaborative. The selected SNFs (n = 47) had significantly higher CMS Five-Star scores than the nonselected SNFs (n = 93) (4.6 vs 3.2, P < .001) and were more likely than nonselected SNFs that met the minimum criteria (n = 35) to have more than 5 days of clinical coverage (17.0% vs 2.9%, P = .02) and to have a physician see admitted individuals within 24 (38.3% vs 17.1%, P = .02) and 48 hours (93.6% vs 80.0%, P = .03). A survey sent to collaborative SNFs found high satisfaction with the process (average satisfaction, 4.6/5, with 1 = very dissatisfied and 5 = very satisfied, n = 19). Although the challenges of improving care in SNFs remain daunting, this approach can serve as a first step toward greater clinical collaboration between acute and postacute settings that will lead to better outcomes for frail older adults.

Validation of Autism Spectrum Disorder Diagnoses in Large Healthcare Systems with Electronic Medical Records.

To identify factors associated with valid Autism Spectrum Disorder (ASD) diagnoses from electronic sources in large healthcare systems. We examined 1,272 charts from ASD diagnosed youth <18 years old. Expert reviewers classified diagnoses as confirmed, probable, possible, ruled out, or not enough information. A total of 845 were classified with 81% as a confirmed, probable, or possible ASD diagnosis. The predictors of valid ASD diagnoses were >2 diagnoses in the medical record (OR 2.94; 95% CI 2.03-4.25; p < 0.001) and being male (OR 1.51; 95% CI 1.05-2.17; p = 0.03). In large integrated healthcare settings, at least two diagnoses can be used to identify ASD patients for population-based research.

Societal costs and morbidity of pertussis in adolescents and adults.

BACKGROUND: Since the 1980s, the reported incidence of pertussis among adolescents and adults has been steadily increasing. To understand whether the benefits of an acellular pertussis vaccine formulated for adolescents and adults might offset its costs, policy makers will need information about morbidity and societal (medical and nonmedical) costs of pertussis. METHODS: Adolescents (age, 10-17 years) and adults (age, >or=18 years) with confirmed pertussis illness were identified by the Massachusetts enhanced pertussis surveillance system. We evaluated medical costs in a cohort of patients who had confirmed pertussis during the period of January 1998 through December 2000; nonmedical costs, by means of prospective interviews, in a cohort of patients who had confirmed pertussis during the period of December 2001 through January 2003; and morbidity in both cohorts. Our main outcome measures were mean costs per case, in 2002 US dollars. RESULTS: In the analysis of medical costs, 1679 adolescents and 936 adults were found to have mean costs of 242 dollars and 326 dollars, respectively (P<.05). In interviews with 314 adolescents and 203 adults, adults had significantly higher nonmedical costs (447 dollars) than those of adolescents (155 dollars). A total of 83% of adolescents missed a mean of 5.5 days from school (range, 0.4-32 days), and 61% of adults missed a mean of 9.8 days from work (range, 0.1-180 days) because of pertussis. Thirty-eight percent of adolescents and 61% of adults were still coughing at the time of the interview, which occurred an average of 106 days and 94 days, respectively, after cough onset. CONCLUSIONS: Pertussis causes significant morbidity in and costs for adolescents and adults, with time losses comprising the largest proportion of the cost. Societal costs should be considered when making decisions about potential vaccine use in the future.

Pediatricians' self-reported clinical practices and adherence to national immunization guidelines after the introduction of pneumococcal conjugate vaccine.

BACKGROUND: Little is known about whether pneumococcal conjugate vaccine (PCV) has altered pediatricians' practices regarding well-child and acute care. OBJECTIVES: To (1) describe whether PCV caused pediatricians to move other routine infant vaccines and/or add routine visits; (2) characterize adherence to national immunization recommendations; and (3) determine whether PCV altered pediatricians' planned clinical approach to well-appearing febrile infants. DESIGN AND METHODS: One year after PCV was added to the pediatric immunization schedule, we mailed a 23-item survey to 691 randomly selected pediatricians in Massachusetts. The adjusted response rate was 77%. RESULTS: After PCV introduction, 39% of pediatricians moved other routine infant vaccines to different visits and 15% added routine visits to the infant schedule. The self-reported immunization schedules of 36% were nonadherent to national immunization guidelines for at least 1 vaccine. Nonadherence rates were significantly higher among pediatricians who had been in practice longer, moved another vaccine because of PCV introduction, and/or offered to give shots later when multiple injections were due. For a hypothetical febrile 8-month-old girl who had received 3 doses of PCV, pediatricians reported they were significantly less likely to (1) perform both blood and urine testing and (2) prescribe antibiotics than in the pre-PCV era. CONCLUSIONS: The introduction of PCV may have had unintended effects on pediatric primary care, including decreased adherence to national recommendations for the timing of immunizations and decreased urine testing for well-appearing febrile infants. Special efforts may be warranted to ensure that pediatricians remain current with changing recommendations.

Factors associated with choice of web or print intervention materials in the healthy directions 2 study.

BACKGROUND: Many U.S. adults have multiple behavioral risk factors, and effective, scalable interventions are needed to promote population-level health. In the health care setting, interventions are often provided in print, although accessible to nearly everyone, are brief (e.g., pamphlets), are not interactive, and can require some logistics around distribution. Web-based interventions offer more interactivity but may not be accessible to all. Healthy Directions 2 was a primary care-based cluster randomized controlled trial designed to improve five behavioral cancer risk factors among a diverse sample of adults (n = 2,440) in metropolitan Boston. Intervention materials were available via print or the web. Purpose. To (a) describe the Healthy Directions 2 study design and (b) identify baseline factors associated with whether participants opted for print or web-based materials. METHODS: Hierarchical regression models corrected for clustering by physician were built to examine factors associated with choice of intervention modality. RESULTS: At baseline, just 4.0% of participants met all behavioral recommendations. Nearly equivalent numbers of intervention participants opted for print and web-based materials (44.6% vs. 55.4%). Participants choosing web-based materials were younger, and reported having a better financial status, better perceived health, greater computer comfort, and more frequent Internet use (p < .05) than those opting for print. In addition, Whites were more likely to pick web-based material than Black participants. CONCLUSIONS: Interventions addressing multiple behaviors are needed in the primary care setting, but they should be available in web and print formats as nearly equal number of participants chose each option, and there are significant differences in the population groups using each modality.

Use of leukotriene receptor antagonists are associated with a similar risk of asthma exacerbations as inhaled corticosteroids.

BACKGROUND: Based on results of clinical trials, inhaled corticosteroids (ICS) are the most-effective controller medications for preventing asthma-related exacerbations, yet few studies in real-life populations have evaluated the comparative effectiveness of ICS. OBJECTIVE: To determine the likelihood of asthma exacerbations among children with asthma after initiation of controller medications: ICS, leukotriene antagonists (LTRA), and ICS-long-acting ß-agonist (LABA) combination therapy. METHODS: This was a retrospective cohort study of subjects who were part of the Population-Based Effectiveness in Asthma and Lung Diseases Network. We conducted Cox regression analyses by adjusting for baseline covariates, adherence by using proportion of days covered, and high-dimensional propensity scores. The main outcome measurements were emergency department visits, hospitalizations, or oral corticosteroid use. RESULTS: Our population included 15,567 health plan subjects and 10,624 TennCare Medicaid subjects with uncontrolled asthma. Overall adherence to controller medications was low, with no more than 50% of the subjects refilling the medication after the initial fill. For subjects with allergic rhinitis, the subjects in TennCare Medicaid treated with LTRAs were less likely to experience ED visits (hazard ratio 0.44 [95% CI, 0.21-0.93]) compared with the subjects treated with ICS. For all other groups, the subjects treated with LTRA or ICS-LABA were just as likely to experience ED visits or hospitalizations, or need oral corticosteroids as the subjects treated with ICS. CONCLUSION: Risks of asthma-related exacerbations did not differ between children who initiated LTRA and ICS. These findings may be explainable by LTRA, which has similar effectiveness as ICS in real-life usage by residual confounding by indication or other unmeasured factors.

Changes in antidepressant use by young people and suicidal behavior after FDA warnings and media coverage: quasi-experimental study.

OBJECTIVE: To investigate if the widely publicized warnings in 2003 from the US Food and Drug Administration about a possible increased risk of suicidality with antidepressant use in young people were associated with changes in antidepressant use, suicide attempts, and completed suicides among young people. DESIGN: Quasi-experimental study assessing changes in outcomes after the warnings, controlling for pre-existing trends. SETTING: Automated healthcare claims data (2000-10) derived from the virtual data warehouse of 11 health plans in the US Mental Health Research Network. PARTICIPANTS: Study cohorts included adolescents (around 1.1 million), young adults (around 1.4 million), and adults (around 5 million). MAIN OUTCOME MEASURES: Rates of antidepressant dispensings, psychotropic drug poisonings (a validated proxy for suicide attempts), and completed suicides. RESULTS: Trends in antidepressant use and poisonings changed abruptly after the warnings. In the second year after the warnings, relative changes in antidepressant use were -31.0% (95% confidence interval -33.0% to -29.0%) among adolescents, -24.3% (-25.4% to -23.2%) among young adults, and -14.5% (-16.0% to -12.9%) among adults. These reflected absolute reductions of 696, 1216, and 1621 dispensings per 100,000 people among adolescents, young adults, and adults, respectively. Simultaneously, there were significant, relative increases in psychotropic drug poisonings in adolescents (21.7%, 95% confidence interval 4.9% to 38.5%) and young adults (33.7%, 26.9% to 40.4%) but not among adults (5.2%, -6.5% to 16.9%). These reflected absolute increases of 2 and 4 poisonings per 100,000 people among adolescents and young adults, respectively (approximately 77 additional poisonings in our cohort of 2.5 million young people). Completed suicides did not change for any age group. CONCLUSIONS: Safety warnings about antidepressants and widespread media coverage decreased antidepressant use, and there were simultaneous increases in suicide attempts among young people. It is essential to monitor and reduce possible unintended consequences of FDA warnings and media reporting.

Using a discrete choice experiment to elicit time trade-off and willingness-to-pay amounts for influenza health-related quality of life at different ages.

BACKGROUND: Recent research suggests that values for health-related quality of life may vary with the age of the patient. Traditional health state valuation questions and discrete choice experiments are two approaches that could be used to value health. OBJECTIVE: To measure whether public values for health vary with the age of the affected individual. METHODS: A discrete choice experiment was administered via the Internet in December 2007 to measure preferences for different attributes of influenza-related health-related quality of life: age of hypothetical affected individual (range 1-85 years), length of episode (days of illness), severity of illness (workdays lost) and time trade-off or willingness-to-pay amounts. Each respondent answered identical choice questions for a hypothetical family member and for himself/herself. Data on sociodemographic characteristics and influenza illness experience were also collected. Respondents were US adults randomly sampled from an Internet survey panel (n = 1,012). The relative value of attributes was estimated using generalized estimating equations and controlling for sociodemographic characteristics and illness experience. Marginal time traded and marginal willingness to pay using discrete choice and traditional time trade-off or willingness-to-pay questions were compared. RESULTS: Respondents preferred shorter influenza episodes but did not significantly prefer fewer workdays lost if episode length was held constant. Respondents were more likely to choose to avert uncomplicated illness in children and less likely to choose to avert uncomplicated illness in working-age adults. Marginal time trade-off and willingness-to-pay amounts elicited using discrete choice questions were larger than those elicited using direct valuation questions. CONCLUSIONS: Approaches that assume values for health-related quality of life do not vary with the age of a patient may bias economic analyses that use these values. If patient age could affect valuations, then age should be included in the valuation exercise. Additional research should evaluate the effect of patient age on values for other conditions.
