Trends of Antihypertensive, Antidiabetic, and Nonsteroidal Anti-Inflammatory Drugs Use among the Health Workers Cohort Study, Mexico 2004 to 2018.

Background: Hypertension and type 2 diabetes (T2D) are the most prevalent noncommunicable diseases in Mexico and worldwide. According to international practice management guidelines, the principal chronic management therapy is daily oral medication. Aim: We aim to describe the trends of antihypertensive, antidiabetic, and nonsteroidal anti-inflammatory (NSAID) drugs use among the Mexican adult population from 2004-2018. Methods: We analyzed data from the Health Workers Cohort Study (HWCS) for males and females aged >18 years. We calculated the prevalence of chronic diseases and utilization for every kind of antihypertensive, antidiabetic, and NSAIDs (measured by self-reported utilization) at baseline and two follow-ups (2004, 2010, and 2017). Trends were analyzed using Fisher's exact test. Results: Hypertension prevalence increased from 19.8 to 30.3%, higher than T2D prevalence from 7.0 to 12.8% through fourteen years of follow-up. Like the self-reported dual therapy, the proportion of patients using beta-blockers and angiotensin II receptor blockers increased. Regarding T2D, the prevalence of metformin utilization increased to 83.9%. The utilization of common NSAIDs, mainly for muscular pain, remained around 13 to 16%. Conclusions: Our findings showed a changing prevalence of drug utilization for hypertension and T2D between 2004 and 2018 and consistent use of NSAIDs in the adult Mexican population.

Availability, prices, and affordability of selected essential cancer medicines in a middle-income country - the case of Mexico.

BACKGROUND: More alternatives have become available for the diagnosis and treatment of cancer in low- and middle-income countries. Because of increasing demands, governments are now facing a problem of limited affordability and availability of essential cancer medicines. Yet, precise information about the access to these medicines is limited, and the methodology is not very well developed. We assessed the availability and affordability of essential cancer medicines in Mexico, and compared their prices against those in other countries of the region. METHODS: We surveyed 21 public hospitals and 19 private pharmacies in 8 states of Mexico. Data were collected on the availability and prices of 49 essential cancer medicines. Prices were compared against those in Chile, Peru, Brazil, Colombia and PAHO's Strategic Fund. RESULTS: Of the various medicines, mean availability in public and private sector outlets was 61.2 and 67.5%, respectively. In the public sector, medicines covered by the public health insurance "People's Health Insurance" were more available. Only seven (public sector) and five (private sector) out of the 49 medicines were considered affordable. Public sector procurement prices were 41% lower than in other countries of the region. CONCLUSIONS: The availability of essential cancer medicines, in the public and private sector, falls below World Health Organization's 80% target. The affordability remains suboptimal as well. A national health insurance scheme could serve as a mechanism to improve access to cancer medicines in the public sector. Comprehensive pricing policies are warranted to improve the affordability of cancer medicines in the private sector.

Common inpatient hypoglycemia phenotypes identified from an automated electronic health record-based prediction model.

PURPOSE: Common inpatient hypoglycemia risk factor patterns (phenotypes) from an electronic health record (EHR)-based prediction model and preventive strategies were identified. METHODS: Patients admitted to 2 large academic medical centers who were in the top fifth percentile of a previously developed hypoglycemia risk score and developed hypoglycemia (blood glucose [BG] of <50mg/dL) were included in the study. Frequencies of all combinations of ≥4 risk factors contributing to the risk score among these patients were determined to identify common risk patterns. Clinical pharmacists developed clinical vignettes for each common pattern and formulated medication therapy management recommendations for hypoglycemia prevention. RESULTS: A total of 401 admissions with a hypoglycemic event were identified among 1,875 admissions whose hypoglycemic risk was in the top fifth percentile among all admissions that received antihyperglycemic drugs and evaluated. Five distinct phenotypes emerged: (1) frail patients with history of hypoglycemia receiving insulin on hospital day 1, (2) a rapid downward trend in BG values in patients receiving an insulin infusion or with a history of hypoglycemia, (3) administration of insulin in the presence of an active nothing by mouth order in frail patients, (4) repeated low BG level in frail patients, and (5) inadequate night-time BG monitoring for patients on long-acting insulin. The 5 themes jointly described 53.0% of high-risk patients who experienced hypoglycemia. CONCLUSION: Five distinct phenotypes that are prevalent in patients at greatest risk for inpatient hypoglycemia were identified.

Retrospective analysis of long-term gastrointestinal symptoms after Clostridium difficile infection in a nonelderly cohort.

Elderly patients and those with comorbid conditions are at high risk for poor outcomes after Clostridium difficile infection (CDI) but outcomes in a healthier, nonelderly population are not well described. We sought to investigate gastrointestinal diagnoses and CDI during hospitalizations in the 24 to 36 months after an initial episode of CDI in nonelderly patients in a cohort with an overall low prevalence of comorbid conditions. We performed a retrospective analysis of hospital admissions from 2010-2013 using the Truven MarketScan database of employment-based private insurance claims. Subjects <65 years of age and their adult dependents (> = 18 years old); a CDI diagnosis in 2011 (index date); at least 12 months of pre-index continuous enrollment; and 24-36 months of continuous post-index enrollment were included. The 12 months of each subject's enrollment prior to the index date for a CDI served as the reference period for the analyses of that subject's post-CDI time periods. Hospital claims during the follow-up period were evaluated for gastrointestinal diagnoses and/or CDI ICD-9 codes. The risk of gastrointestinal diagnoses was assessed using Cox proportional hazards models adjusted for a pre-specified set of baseline demographic and clinical factors. During 2011, 5,632 subjects with CDI met the inclusion criteria for our study. The risk of gastrointestinal diagnoses in patients with a CDI diagnostic code for the same admission was almost 8-fold higher 3 months post-CDI (hazard ratio (HR) = 7.56; 95% confidence interval (CI): 2.97-19.19) than for subjects without CDI and remained statistically significant until month 24 (HR = 1.47; 95% CI = 1.04-2.08). After CDI, patients remained at risk for gastrointestinal symptoms with CDI for up to two years. There is an important, long-term healthcare burden after CDI in this population.

Access to innovative cancer medicines in a middle-income country - the case of Mexico.

BACKGROUND: Cancer has become the third cause of death in Mexico. Treatment for cancer is often complex and lengthy. New and better medicines enter the market at high prices, which may limit access. Like most Latin American countries, Mexico has an essential cancer medicines list that includes innovative medicines. Their accessibility and use in the public sector remains unknown. Therefore, we describe the use, as a proxy of access, of innovative and essential cancer medicines in the public sector in Mexico, by insurance institution, and by five regions between 2010 to 2016. METHODS: We used drug utilization research methods to assess the use of eight patented cancer medicines. Through the national transparency platform, we obtained data on the quantities of these medicines used in all public health facilities and social health insurance institutions and recalculated those figures into defined daily dose (DDD) per 1000 population per year. RESULTS: Overall, the use of all medicines increased over the years, especially for trastuzumab, rituximab and imatinib. The use of innovative medicines was higher per population covered in social health insurance institutions than in governmental facilities. Throughout the study period, the Central region (including Mexico City) has used more medicines per population than the other regions. CONCLUSIONS: The use and access of some essential innovative cancer medicines has increased over the years, but remains unequal across insurance schemes and regions. Particularly, the Ministry of Health Insurance scheme and Northern and Western regions in the country would benefit from additional efforts to increase access to essential cancer medicines.

Factors That Predict the Use of Psychotropics Among Children and Adolescents With PTSD: Evidence From Private Insurance Claims.

OBJECTIVE: This study aimed to determine which characteristics of youths with posttraumatic stress disorder (PTSD) were associated with receiving prescriptions for antidepressants, antipsychotics, or benzodiazepines. METHODS: A 2011-2012 retrospective cohort of children and adolescents with a new episode of PTSD was extracted from medical and pharmacy claims from a nationally representative sample of privately insured persons. Multivariate logistic regression assessed attributes (demographic characteristics, mental and general medical comorbidities, insurance arrangements, specialty type, and geographic location) associated with utilization of antidepressants, antipsychotics, and benzodiazepines. RESULTS: Among 7,726 youths with a new episode of PTSD in 2012, just less than 60% received psychotherapy alone, about 6% received pharmacotherapy, and about 35% received neither psychotherapy nor pharmacotherapy. Among utilizers of medications, 71.3% used antidepressants and 21.6% used antipsychotics. Youths prescribed medication tended to be older and have more general medical and mental comorbidities. Provider specialty, capitated insurance arrangements, and more comorbidities predicted being prescribed antidepressants. History of hospitalization, noncapitated insurance arrangements, nonuse of psychotherapy, and more comorbidities predicted being prescribed antipsychotics. Antidepressants and antipsychotics were more likely to be used in the South. CONCLUSIONS: Only three-fifths of youths with PTSD received first-line treatment (psychotherapy). More than one in 20 received pharmacotherapy, which appeared to be associated with the most severe and complex presentations. More than one-third of youths with PTSD received neither therapy nor medication, signaling compromised quality of care. Future research should confirm the factors associated with pharmacotherapy prescription and explore ways to increase the use of psychotherapy in primary care.

Prevalence, Time Trends, and Utilization Patterns of Psychotropic Polypharmacy Among Pediatric Medicaid Beneficiaries, 1999-2010.

OBJECTIVES: This study estimated the prevalence, time trends, and state-level variation of same- and multiclass psychotropic polypharmacy among youths in Medicaid fee-for-service plans. METHODS: Using pharmacy records from 29 Medicaid states from 1999 to 2010, the authors constructed ten two-year cohorts of beneficiaries between ages 0 and 17 years who received at least one psychotropic to treat a mental disorder. Polypharmacy was defined as any period in which dispensed days' supply of psychotropics overlapped for more than 45 days. Same- and multiclass psychotropic polypharmacy prevalence was stratified by age and state. RESULTS: A total of 692,485 children were included across each two-year cohort. The prevalence of any-class and multiclass psychotropic polypharmacy grew steadily, from 21.2% and 18.8% in 1999-2000 to 27.3% and 24.4% in 2009-2010, respectively. The prevalence increased with older age, with highest estimates for late adolescents. For same-class psychotropic polypharmacy, a constant upward trend was noted over time, except for antidepressants. Polypharmacy increased over the decade for central nervous system stimulants, from .1% to .6%, and for alpha-agonists, from .1% to .4%. Heterogeneous prevalences of psychotropic polypharmacy were noted across states, ranging from 6.9% to 48.8% for any-class psychotropic polypharmacy, from .4% to 6.4% for same-class antidepressant polypharmacy, and from .1% to 4.6% for antipsychotics. CONCLUSIONS: The study found an overall increasing trend of psychotropic polypharmacy coupled with significant variation across the examined states. A more granular assessment that considers patient characteristics and local contextual factors is warranted.

The prevalence and correlates of severe depression in a cohort of Mexican teachers.

BACKGROUND: Depression is among the 10 major causes of disability in Mexico. Yet, local contextual factors associated to the disorder remain poorly understood. We measured the impact of several factors on severe depression such as demographics, pharmacotherapy, multimorbidity, and unhealthy behaviors in Mexican teachers. METHODS: A total of 43,845 Mexican female teachers from 12 Mexican states answered the Patient Health Questionnaire (PHQ9). Data were part the Mexican Teacher's Cohort prospective study, the largest ongoing cohort study in Latin America. Unadjusted and adjusted estimates assessed the impact of several contextual factors between severe versus mild-no depression cases. RESULTS: In total 7026 teachers (16%) had a PHQ9 score compatible with severe depression. From them, only 17% received psychotropics, compared to 60% for those with a formal diagnosis. Less than 5% of teachers with PHQ9 scores compatible with severe depression had a formal diagnosis. Adjusted analysis reported higher odds of pharmacotherapy, having ≥ 3 comorbidities, higher levels of couple, family and work stress, fewer hours of vigorous physical activity, higher alcohol consumption, and smoking as risk factors for severe depression. Also, rural residents of northern and center states appeared more severely depressed compared to their urban counterparts. On average, the PHQ9 scores differed by ~ 10 points between severe and mild-no depressed teachers. LIMITATIONS: A cross-sectional design. Also, the study focused on female teachers between ages 25 and 74 years old, reducing the generalizability of the estimates. CONCLUSION: Under-diagnosis of clinical depression in Mexican teachers is concerning. Unhealthy behavior is associated with severe depression. The information collected in this study represents an opportunity to build prevention mechanisms of depression in high-risk subgroups of female educators and warrants improving access to mental care in Mexico.

Development and validation of a complexity score to rank hospitalized patients at risk for preventable adverse drug events.

PURPOSE: The development of risk models for 16 preventable adverse drug events (pADEs) and their aggregation into the final complexity score (C-score) are described. METHODS: Using data from 2 tertiary care facilities, logistic regression models were constructed for the first 5 hospital days that admissions were at risk for each of 16 pADEs. The best model for each pADE was validated in 100 bootstrap samples. The C-score was then aggregated and predicted individual pADE risk as the probability to develop at least 1 pADE. Using the 100 bootstrap samples for each pADE, 100 C-scores for validation were generated. RESULTS: We utilized electronic health records (EHR) data from 65,518 admissions to UF Health Shands and 18,269 admissions to UF Health Jacksonville to develop risk models for 16 pADEs. Most models had very strong discriminant validity (C-statistic > 0.8), with the highest predicted decile representing about half of manifest pADEs. Among admissions in the highest C-score decile, about two thirds experienced at least 1 pADE (C-statistic, 0.838; 95% confidence interval, 0.838-0.839). C-score precision, defined as the percentage of patients consistently (i.e., at least 95 of 100 samples) ranked in the 90th percentile, was 80-84%. CONCLUSION: The C-score was developed and validated for the identification of hospitalized patients at highest risk for pADEs. Aggregation of individual prediction models into a single score reduced its predictive power for most pADEs, compared with the individual risk models, but concentrated in the highest C-score decile a patient group more than two thirds of whom experienced at least 1 pADE.

Region and Insurance Plan Type Influence Discharge Disposition After Hip and Knee Arthroplasty: Evidence From the Privately Insured US Population.

BACKGROUND: Little is known about regional variation in the use of postacute care services after elective procedures, such as total hip or knee arthroplasty (THA/TKA), and how insurance type may influence it. The goal of this study is to assess the influence of region and insurance arrangements on discharge disposition. METHODS: A representative sample of the privately insured US population with THA or TKA in 2009 or 2010 was obtained from the MarketScan database applying individual-level weights from the Medical Expenditure Panel Survey. Multivariate logistic regression was used to predict the odds of being discharged to an extended care facility (ECF) compared with being discharged home. The model adjusted for region, insurance plan type, sociodemographic characteristics, comorbidities, and length of stay. RESULTS: Large variability was observed in ECF use across the US. Patients in the Northeast were 2.5 times more likely to receive care at an ECF compared with patients in the South (odds ratio [OR] = 2.51, 95% confidence interval [CI]: 1.97-3.19). Enrollees in noncapitated plans such as fee-for-service plans or exclusive provider organizations were less likely to be discharged to an ECF compared with health maintenance organizations/preferred provider organizations with capitation enrollees (OR = 0.74, 95% CI: 0.57-0.94; OR = 0.49, 95% CI: 0.34-0.74, respectively). CONCLUSION: Region and private insurance plan arrangements are related to extended care use among THA and TKA patients. Understanding regional variation in discharge disposition provides policy makers with important information as to where to focus new tests of hip and knee procedures such as same day arthroplasty.

Differential Risk of Increasing Psychotropic Polypharmacy Use in Children Diagnosed With ADHD as Preschoolers.

OBJECTIVE: To characterize treatment trajectories in children newly diagnosed with attention-deficit/hyperactivity disorder (ADHD). METHODS: We utilized billing records of children aged 3 to 18 years in 28 US states' Medicaid programs between 1999 and 2006. Children entered the cohort at the first ADHD diagnosis (ICD-9-CM: 314.00) preceded by ≥ 6 months with no psychotropic medication use and no psychiatric diagnoses. We followed children for 5 years to assess use of (1) psychotropic polypharmacy (the use of ≥ 3 psychotropic medication classes), (2) antipsychotics, and (3) anticonvulsants. We used mixed-effects logistic regression to model the probability of each utilization outcome as a function of age at ADHD diagnosis and follow-up year, adjusted for sociodemographic factors. RESULTS: Our cohort included 16,626 children of whom 79.2% received stimulants, 33.2% antidepressants, and 23.1% α-agonists, and 25.3% received psychotropic polypharmacy treatment at least once in a subsequent year. Antipsychotics (7.1%-14.7%), anticonvulsants (4.0%-7.9%), and psychotropic polypharmacy (8.5%-13.4%) use increased from year 1 to 5, but this increase was confined to children between ages 3 and 9 at ADHD diagnosis. Children diagnosed at age 3 had the most substantial increase in each outcome (OR = 1.80 [95% CI, 1.36-2.38]; 1.85 [1.38-2.47]; 2.14 [1.45-3.16]), respectively. Also, 39.1% of 9,680 children-years with psychotropic polypharmacy therapy had no psychiatric diagnoses other than ADHD. CONCLUSIONS: Psychotropic polypharmacy, antipsychotic, and anticonvulsant use increased with each year of follow-up. This effect was strongly mediated by the age of ADHD diagnosis with substantial increases in preschoolers but no corresponding effect in older children. It was only partially explained by physician diagnoses of concomitant mental disorders.

Associations Between Medication Class and Subsequent Augmentation of Depression Treatment in Privately Insured US Adults.

IMPORTANCE: Treatment augmentation is an important clinical decision in the pharmacotherapy for depression, yet few studies have examined the rates of treatment augmentation by medication class. OBJECTIVE: The aim of this study was to examine which initial pharmacotherapies for depression are more likely than others to result in subsequent treatment augmentation. METHODS: This study is a retrospective cohort analysis of administrative data of 214,705 privately insured US adults between the age of 18 and 64 years who were diagnosed with a new episode of depression in 2009. Propensity score-adjusted logistic regression and Cox regression were used to model the effect of the class of initial monotherapy on treatment augmentation. Risk adjustors included depression severity, comorbidities, provider type, insurance, and demographic characteristics. EXPOSURE: The class of initial monotherapy and the health care provider type were the main independent variables of interest. MAIN OUTCOME: The outcome was the augmentation of monotherapy. RESULTS: Thirty-four percent of individuals received treatment augmentation. Compared with selective serotonin reuptake inhibitor monotherapy, second-generation antipsychotics as the initial treatment were associated with significant increase in the likelihood of augmentation compared with the other classes (hazards ratio, 2.59; 95% confidence interval [CI], 2.51-2.68). This result was corroborated after propensity score adjustment (odds ratio, 2.85; 95% CI, 2.70-3.00) when comparing second-generation antipsychotics to the other classes of pharmacotherapy. The other significant predictor of treatment augmentation was the provider type. Mental health specialists were 27% more likely to augment a treatment compared with generalists (hazards ratio, 1.27; 95% CI, 1.25-1.30). CONCLUSIONS: The type of initial antidepressant therapy is associated with the chances of treatment augmentation. Second-generation antipsychotics progressed to augmentation more rapidly than the other classes.

Measuring the Social Impact of Burns on Survivors.

Many burn survivors experience social challenges throughout their recovery. Measuring the social impact of a burn injury is important to identify opportunities for interventions. The aim of this study is to develop a pool of items addressing the social impact of burn injuries in adults to create a self-reported computerized adaptive test based on item response theory. The authors conducted a comprehensive literature review to identify preexisting items in other self-reported measures and used data from focus groups to create new items. The authors classified items using a guiding conceptual framework on social participation. The authors conducted cognitive interviews with burn survivors to assess clarity and interpretation of each item. The authors evaluated an initial pool of 276 items with burn survivors and reduced this to 192 items after cognitive evaluation by experts and burn survivors. The items represent seven domains from the guiding conceptual model: work, recreation and leisure, relating to strangers, romantic, sexual, family, and informal relationships. Additional item content that crossed domains included using self-comfort and others' comfort with clothing, telling one's story, and sense of purpose. This study was designed to develop a large item pool based on a strong conceptual framework using grounded theory analysis with focus groups of burn survivors and their caregivers. The 192 items represent 7 domains and reflect the unique experience of burn survivors within these important areas of social participation. This work will lead to developing the Life Impact Burn Recovery Evaluation profile, a self-reported outcome measure.

Development of a Conceptual Framework to Measure the Social Impact of Burns.

Measuring community reintegration following burn injury is important to assess the efficacy of therapies designed to optimize recovery. This project aims to develop and validate a conceptual framework for understanding the social impact of burn injuries in adults. The framework is critical for developing the item banks used for a computerized adaptive test. We performed a comprehensive literature review and consulted with clinical experts and burn survivors about social life areas impacted by burn injury. Focus groups with burn survivors and clinicians were conducted to inform and validate the framework. Transcripts were coded using grounded theory methodology. The World Health Organization's International Classification of Functioning, Disability and Health, was chosen to ground the content model. The primary construct identified was social participation, which contains two concepts: societal role and personal relationships. The subdomains chosen for item development were work, recreation and leisure, relating with strangers, and romantic, sexual, family, and informal relationships. Qualitative results strongly suggest that the conceptual model fits the constructs for societal role and personal relationships with the respective subdomains. This conceptual framework has guided the implementation of a large-scale calibration study currently underway which will lead to a computerized adaptive test for monitoring the social impacts of burn injuries during recovery.

Unnecessary Antibiotics for Acute Respiratory Tract Infections: Association With Care Setting and Patient Demographics.

Background. Up to 40% of antibiotics are prescribed unnecessarily for acute respiratory tract infections (ARTIs). We sought to define factors associated with antibiotic overprescribing of ARTIs to inform efforts to improve practice. Methods. We conducted a retrospective analysis of ARTI visits between 2006 and 2010 from the National Ambulatory Medical Care Survey and the National Hospital Ambulatory Medical Care Survey. Those surveys provide a representative sample of US visits to community-based physicians and to hospital-based emergency departments (EDs) and outpatient practices. Patient factors (age, sex, race, underlying lung disease, tobacco use, insurance), physician specialty, practice demographics (percentage poverty, median household income, percentage with a Bachelor's Degree, urban-rural status, geographic region), and care setting (ED, hospital, or community-based practice) were evaluated as predictors of antibiotic overprescribing for ARTIs. Results. Hospital and community-practice visits had more antibiotic overprescribing than ED visits (odds ratio [OR] = 1.64 and 95% confidence interval [CI], 1.27-2.12 and OR = 1.59 and 95% CI, 1.26-2.01, respectively). Care setting had significant interactions with geographic region and urban and rural location. The quartile with the lowest percentage of college-educated residents had significantly greater overprescribing (adjusted OR = 1.41; 95% CI, 1.07-1.86) than the highest quartile. Current tobacco users were overprescribed more often than nonsmokers (OR = 1.71; 95% CI, 1.38-2.12). Patient age, insurance, and provider specialty were other significant predictors. Conclusions. Tobacco use and a lower grouped rate of college education were associated with overprescribing and may reflect poor health literacy. A focus on educating the patient may be an effective approach to stewardship.

Receipt of Evidence-Based Pharmacotherapy and Psychotherapy Among Children and Adolescents With New Diagnoses of Depression.

OBJECTIVE: Little is known about utilization rates of the various depression treatment options available in the private sector for children and adolescents. For privately insured youths, this study examined the utilization frequency of six treatment options for depression with varying degrees of empirical support. METHODS: A nationally representative administrative claims database of privately insured individuals (Truven Analytics database, 2008-2010) was used to construct a cohort of 61,599 youths (ages six to 17 years) with depression. Multivariable logistic regression controlling for insurance type, region, and illness severity and complexity assessed, by physician specialty, the likelihood of receiving six different depression treatments (medication combined with psychotherapy, first-line medication, second-line medication, non-evidence-based medication, second-generation antipsychotics, and psychotherapy alone). RESULTS: Only 58.4% of depressed youths received at least one type of depression treatment; 33.6% received psychotherapy alone, 24.8% received medication alone, and 2.7% received combination treatment. Of depressed youths receiving only medication, 24.8% received medications unsupported by empirical evidence (non-evidence-based or second-generation antipsychotics) and 50.6% received medications with equivocal support. Mental health specialists were approximately nine times (odds ratio=8.61) more likely than primary care providers to prescribe combination treatment. Other predictors of receiving combination treatment included having diagnosed major depressive disorder, being a young adolescent (ages 12-14), and residing in the Northeast. CONCLUSIONS: Large proportions of depressed youths are not receiving any treatment or are receiving treatments unsupported or equivocally supported by empirical evidence. Additional research is warranted to assess factors associated with nonrecommended use of pharmacotherapies for youths with depression.

The Role of Geography in the Assessment of Quality: Evidence from the Medicare Advantage Program.

The Affordable Care Act set in motion a renewed emphasis on quality of care evaluation. However, the evaluation strategies of quality by the Centers for Medicare and Medicaid Services do not consider geography when comparisons are made among plans. Using an overall measure of a plan's quality in the public sector--the Medicare Advantage (MA) star ratings--we explored the impact of geography in these ratings. We identified 2,872 U.S counties in 2010. The geographic factor predicted a larger fraction of the MA ratings' compared to socio-demographic factors which explained less. Also, after the risk adjustments, almost half of the U.S. states changed their ranked position in the star ratings. Further, lower MA star ratings were identified in the Southeastern region. These findings suggest that the geographic component effect on the ratings is not trivial and should be considered in future adjustments of the metric, which may enhance the transparency, accountability, and importantly level the playing field more effectively when comparing quality across health plans.

Patient cost-sharing and insurance arrangements are associated with hospital readmissions after abdominal surgery: Implications for access and quality health care.

BACKGROUND: Readmission rates after operative procedures are used increasingly as a measure of hospital care quality. Patient access to care may influence readmission rates. The objective of this study was to determine the relationship between patient cost-sharing, insurance arrangements, and the risk of postoperative readmissions. METHODS: Using the MarketScan Research Database (n = 121,002), we examined privately insured, nonelderly patients who underwent abdominal surgery in 2010. The main outcome measures were risk-adjusted unplanned readmissions within 7 days and 30 days of discharge. Odds of readmissions were compared with multivariable logistic regression models. RESULTS: In adjusted models, $1,284 increase in patient out-of-pocket payments during index admission (a difference of one standard deviation) was associated with 19% decrease in the odds of 7-day readmission (odds ratio [OR] 0.81, 95% confidence interval [CI] 0.78-0.85) and 17% decrease in the odds of 30-day readmission (OR 0.83, 95% CI 0.81-0.86). Patients in the noncapitated point-of-service plans (OR 1.19, 95% CI 1.07-1.33), preferred provider organization plans (OR 1.11, 95% CI 1.03-1.19), and high-deductible plans (OR 1.12, 95% CI 1.00-1.26) were more likely to be readmitted within 30 days compared with patients in the capitated health maintenance organization and point-of-service plans. CONCLUSION: Among privately insured, nonelderly patients, increased patient cost-sharing was associated with lower odds of 7-day and 30-day readmission after abdominal surgery. Insurance arrangements also were significantly associated with postoperative readmissions. Patient cost sharing and insurance arrangements need consideration in the provision of equitable access for quality care.

Relationships between Medicare Advantage contract characteristics and quality-of-care ratings: an observational analysis of Medicare Advantage star ratings.

BACKGROUND: The Centers for Medicare & Medicaid Services (CMS) publishes star ratings on Medicare Advantage (MA) contracts to measure plan quality of care with implications for reimbursement and bonuses. OBJECTIVE: To investigate whether MA contract characteristics are associated with quality of care through the Medicare plan star ratings. DESIGN: Retrospective study of MA star ratings in 2010. Unadjusted and adjusted multivariable linear regression models assessed the relationship between 5-star rating summary scores and plan characteristics. SETTING: CMS MA contracts nationally. PARTICIPANTS: 409 (71%) of a total of 575 MA contracts, covering 10.56 million Medicare beneficiaries (90% of the MA population) in the United States in 2010. MEASUREMENTS: The MA quality ratings summary score (stars range from 1 to 5) is a quality measure based on 36 indicators related to processes of care, health outcomes, access to care, and beneficiary satisfaction. RESULTS: Nonprofit, larger, and older MA contracts were more likely to receive higher star ratings. Star ratings ranged from 2 to 5. Nonprofit contracts received an average 0.55 (95% CI, 0.42 to 0.67) higher star ratings than for-profit contracts (P  < 0.001) after controls were set for contract characteristics. LIMITATION: The study focused on persons aged 65 years or older covered by MA. CONCLUSION: In 2010, nonprofit MA contracts received significantly higher star ratings than for-profit contracts. When comparing health plans in the future, the CMS should give increasing attention to for-profit plans with lower quality ratings and consider developing programs to assist newer and smaller plans in improving their care for Medicare beneficiaries. PRIMARY FUNDING SOURCE: None.
