The effect of increased emergency department demand on throughput times and disposition status for pediatric psychiatric patients.

OBJECTIVES: Emergency department (ED) crowding has been shown to increase throughput measures of length of stay (LOS), wait time, and boarding time. Psychiatric utilization of the ED has increased, particularly among younger patients. This investigation quantifies the effect of ED demand on throughput times and discharge disposition for pediatric psychiatric patients in the ED. METHODS: Using electronic medical record data from 1,151,396 ED visits in eight North Carolina EDs from January 1, 2018, through December 31, 2020, we identified 14,092 pediatric psychiatric visits. Measures of ED daily demand rates included overall occupancy as well as daily proportion of non-psychiatric pediatric patients, adult psychiatric patients, and pediatric psychiatric patients. Controlling for patient-level factors such as age, sex, race, insurance, and triage acuity, we used linear regression to predict throughput times and logistic regression to predict disposition status. We estimated effects of ED demand by academic versus community hospital status due to ED and inpatient resource differences. RESULTS: Most ED demand measures had insignificant or only very small associations with throughput measures for pediatric psychiatric patients. Notable exceptions were that a one percentage point increase in the proportion of non-psychiatric pediatric ED visits increased boarding times at community sites by 1.06 hours (95% CI: 0.20-1.92), while a one percentage point increase in the proportion of pediatric psychiatric ED visits increased LOS by 3.64 hours (95% CI: 2.04-5.23) at the academic site. We found that ED demand had a minimal effect on disposition status, with small increases in demand rates favoring <1 percentage point increases in the likelihood of discharge. Instead, patient-level factors played a much stronger role in predicting discharge disposition. CONCLUSIONS: ED demand has a meaningful effect on throughput times, but a minimal effect on disposition status. Further research is needed to validate these findings across other state and healthcare systems.

The Landscape of State Policies Supporting Family Caregivers as Aligned With the National Academy of Medicine Recommendations.

Policy Points In the absence of federal policy, states adopted policies to support family caregivers, but availability and level of support varies. We describe, compare, and rank state policies to support family caregivers as aligned with National Academy of Medicine recommendations. Although the landscape of state policies supporting caregivers has improved over time, few states provide financial supports as recommended, and benefit restrictions hinder accessibility for all types of family caregivers. Implementing policies supporting family caregivers will become more critical over time, as the reliance on family caregivers as essential providers of long-term care is only expected to grow as the population ages. CONTEXT: In the United States in 2020, approximately 26 million individuals provided unpaid care to a family member or friend. On average, 60% of caregivers were employed, and they provided 20.4 hours of care per week on top of employment. Although a handful of patchwork laws exist to aid family caregivers, systematic supports, including comprehensive training, respite, and financial support, remain limited. In the absence of federal supports, states have adopted policies to provide assistance, but they vary in availability and level of support provided. Our objectives were to describe, compare, and rank state policies to support family caregivers over time. METHODS: We used publicly available data from the AARP Long-Term Services and Supports State Scorecard, the National Academy for State Health Policy, and Tax Credits for Workers and Families for all 50 states and the District of Columbia (2015-2019). FINDINGS: We found that states had increased supports to family caregivers over this five-year period, although significant variability in adoption and implementation of policies persists. Approximately 20% of states had enacted policies that exceed the federal Family and Medical Leave Act requirements, and 18% offered paid family leave. However, most states had not improved spousal impoverishment protections for Medicaid beneficiaries. For example, from 2016 to 2019, 24% of states provided fewer or no protections, while 71% of states did not improve spousal impoverishment protections over time. Access to training for caregivers varied based on eligibility criteria (e.g., select populations and/or only co-residing caregivers). CONCLUSIONS: Overall, state approaches to support family caregivers vary by eligibility and scope of services. Substantial gaps in support of caregivers, particularly economic supports, persist. Although the landscape of state policies supporting caregivers has improved over time, few states provide financial supports as recommended by the National Academy of Medicine, and benefit restrictions hinder accessibility for all family caregivers.

The Medicare Shared Savings Program and Outcomes for Ischemic Stroke Patients: a Retrospective Cohort Study.

BACKGROUND: Post-stroke care delivery may be affected by provider participation in Medicare Shared Savings Program (MSSP) Accountable Care Organizations (ACOs) through systematic changes to discharge planning, care coordination, and transitional care. OBJECTIVE: To evaluate the association of MSSP with patient outcomes in the year following hospitalization for ischemic stroke. DESIGN: Retrospective cohort SETTING: Get With The Guidelines (GWTG)-Stroke (2010-2014) PARTICIPANTS: Hospitalizations for mild to moderate incident ischemic stroke were linked with Medicare claims for fee-for-service beneficiaries ≥ 65 years (N = 251,605). MAIN MEASURES: Outcomes included discharge to home, 30-day all-cause readmission, length of index hospital stay, days in the community (home-time) at 1 year, and 1-year recurrent stroke and mortality. A difference-in-differences design was used to compare outcomes before and after hospital MSSP implementation for patients (1) discharged from hospitals that chose to participate versus not participate in MSSP or (2) assigned to an MSSP ACO versus not or both. Unique estimates for 2013 and 2014 ACOs were generated. KEY RESULTS: For hospitals joining MSSP in 2013 or 2014, the probability of discharge to home decreased by 2.57 (95% confidence intervals (CI) = - 4.43, - 0.71) percentage points (pp) and 1.84 pp (CI = - 3.31, - 0.37), respectively, among beneficiaries not assigned to an MSSP ACO. Among discharges from hospitals joining MSSP in 2013, beneficiary ACO alignment versus not was associated with increased home discharge, reduced length of stay, and increased home-time. For patients discharged from hospitals joining MSSP in 2014, ACO alignment was not associated with changes in utilization. No association between MSSP and recurrent stroke or mortality was observed. CONCLUSIONS: Among patients with mild to moderate ischemic stroke, meaningful reductions in acute care utilization were observed only for ACO-aligned beneficiaries who were also discharged from a hospital initiating MSSP in 2013. Only 1 year of data was available for the 2014 MSSP cohort, and these early results suggest further study is warranted. REGISTRATION: None.

Heart Failure and Cognitive Impairment in the Atherosclerosis Risk in Communities (ARIC) Study.

BACKGROUND: Previous studies suggest that heart failure (HF) is an independent risk factor for cognitive decline. A better understanding of the relationship between HF, cognitive status, and cognitive decline in a community-based sample may help clinicians understand disease risk. OBJECTIVE: To examine whether persons with HF have a higher prevalence of cognitive impairment and whether persons developing HF have more rapid cognitive decline. DESIGN: This observational cohort study of American adults in the Atherosclerosis Risk in Communities (ARIC) study has two components: cross-sectional analysis examining the association between prevalent HF and cognition using multinomial logistic regression, and change over time analysis detailing the association between incident HF and change in cognition over 15 years. PARTICIPANTS: Among visit 5 (2011-2013) participants (median age 75 years), 6495 had neurocognitive information available for cross-sectional analysis. Change over time analysis examined the 5414 participants who had cognitive scores and no prevalent HF at visit 4 (1996-1998). MEASUREMENTS: The primary outcome was cognitive status, classified as normal, mild cognitive impairment [MCI], and dementia on the basis of standardized cognitive tests (delayed word recall, word fluency, and digit symbol substitution). Cognitive change was examined over a 15-year period. Control variables included socio-demographic, vascular, and smoking/drinking measures. RESULTS: At visit 5, participants with HF had a higher prevalence of dementia (adjusted relative risk ratio [RRR] = 1.60 [95% CI 1.13, 2.25]) and MCI (RRR = 1.36 [1.12, 1.64]) than those without HF. A decline in cognition between visits 4 and 5 was - 0.07 standard deviation units [- 0.13, - 0.01] greater among persons who developed HF compared to those who did not. Results did not differ by ejection fraction. CONCLUSION: HF is associated with neurocognitive dysfunction and decline independent of other co-morbid conditions. Further study is needed to determine the underlying pathophysiology.

Position matters: Validation of medicare hospital claims for myocardial infarction against medical record review in the atherosclerosis risk in communities study.

PURPOSE: The objectives of this study were to investigate sensitivity and specificity of myocardial infarction (MI) case definitions using multiple discharge code positions and multiple diagnosis codes when comparing administrative data to hospital surveillance data. METHODS: Hospital surveillance data for ARIC Study cohort participants with matching participant ID and service dates to Centers for Medicare and Medicaid Services (CMS) hospitalization records for hospitalizations occurring between 2001 and 2013 were included in this study. Classification of Definite or Probable MI from ARIC medical record review defined "gold standard" comparison for validation measures. In primary analyses, an MI was defined with ICD9 code 410 from CMS records. Secondary analyses defined MI using code 410 in combination with additional codes. RESULTS: A total of 25 549 hospitalization records met study criteria. In primary analysis, specificity was at least 0.98 for all CMS definitions by discharge code position. Sensitivity ranged from 0.48 for primary position only to 0.63 when definition included any discharge code position. The sensitivity of definitions including codes 410 and 411.1 were higher than sensitivity observed when using code 410 alone. Specificity of these alternate definitions was higher for women (0.98) than for men (0.96). CONCLUSION: Algorithms that rely exclusively on primary discharge code position will miss approximately 50% of all MI cases due to low sensitivity of this definition. We recommend defining MI by code 410 in any of first 5 discharge code positions overall and by codes 410 and 411.1 in any of first 3 positions for sensitivity analyses of women.

Costs at the End of Life: Perspectives for North Carolina.

Many elders require supportive services, with many costs covered by Medicaid. Once terminal illness sets in, palliative care and hospice may help control cost while ensuring quality. This commentary reviews trends in cost at the end of life and describes selected strategies to improve patient-centered care in North Carolina.

The US President's Malaria Initiative and under-5 child mortality in sub-Saharan Africa: A difference-in-differences analysis.

BACKGROUND: Despite substantial financial contributions by the United States President's Malaria Initiative (PMI) since 2006, no studies have carefully assessed how this program may have affected important population-level health outcomes. We utilized multiple publicly available data sources to evaluate the association between introduction of PMI and child mortality rates in sub-Saharan Africa (SSA). METHODS AND FINDINGS: We used difference-in-differences analyses to compare trends in the primary outcome of under-5 mortality rates and secondary outcomes reflecting population coverage of malaria interventions in 19 PMI-recipient and 13 non-recipient countries between 1995 and 2014. The analyses controlled for presence and intensity of other large funding sources, individual and household characteristics, and country and year fixed effects. PMI program implementation was associated with a significant reduction in the annual risk of under-5 child mortality (adjusted risk ratio [RR] 0.84, 95% CI 0.74-0.96). Each dollar of per-capita PMI expenditures in a country, a measure of PMI intensity, was also associated with a reduction in child mortality (RR 0.86, 95% CI 0.78-0.93). We estimated that the under-5 mortality rate in PMI countries was reduced from 28.9 to 24.3 per 1,000 person-years. Population coverage of insecticide-treated nets increased by 8.34 percentage points (95% CI 0.86-15.83) and coverage of indoor residual spraying increased by 6.63 percentage points (95% CI 0.79-12.47) after PMI implementation. Per-capita PMI spending was also associated with a modest increase in artemisinin-based combination therapy coverage (3.56 percentage point increase, 95% CI -0.07-7.19), though this association was only marginally significant (p = 0.054). Our results were robust to several sensitivity analyses. Because our study design leaves open the possibility of unmeasured confounding, we cannot definitively interpret these results as causal. CONCLUSIONS: PMI may have significantly contributed to reducing the burden of malaria in SSA and reducing the number of child deaths in the region. Introduction of PMI was associated with increased coverage of malaria prevention technologies, which are important mechanisms through which child mortality can be reduced. To our knowledge, this study is the first to assess the association between PMI and all-cause child mortality in SSA with the use of appropriate comparison groups and adjustments for regional trends in child mortality.

A Comparison of Self-reported Medication Adherence to Concordance Between Part D Claims and Medication Possession.

OBJECTIVE: Medicare Part D claims indicate medication purchased, but people who are not fully adherent may extend prescription use beyond the interval prescribed. This study assessed concordance between Part D claims and medication possession at a study visit in relation to self-reported medication adherence. MATERIALS AND METHODS: We matched Part D claims for 6 common medications to medications brought to a study visit in 2011-2013 for the Atherosclerosis Risk in Communities study. The combined data consisted of 3027 medication events (claims, medications possessed, or both) for 2099 Atherosclerosis Risk in Communities study participants. Multinomial logistic regression estimated the association of concordance (visit only, Part D only, or both) with self-reported medication adherence while controlling for sociodemographic characteristics, veteran status, and availability under Generic Drug Discount Programs. RESULTS: Relative to participants with high adherence, medication events for participants with low adherence were approximately 25 percentage points less likely to match and more likely to be visit only (P<0.001). The results were similar but smaller in magnitude (approximately 2-3 percentage points) for participants with medium adherence. Compared with females, medication events for male veterans were approximately 11 percentage points less likely to match and more likely to be visit only. Events for medications available through Generic Drug Discount Programs were 3 percentage points more likely to be visit only. CONCLUSIONS: Part D claims were substantially less likely to be concordant with medications possessed at study visit for participants with low self-reported adherence. This result supports the construction of adherence proxies such as proportion days covered using Part D claims.

Mind the Gap: Hospitalizations from Multiple Sources in a Longitudinal Study.

BACKGROUND: Medicare claims and prospective studies with self-reported utilization are important sources of hospitalization data for epidemiologic and outcomes research. OBJECTIVES: To assess the concordance of Medicare claims merged with interview-based surveillance data to determine factors associated with source completeness. METHODS: The Atherosclerosis Risk in Communities (ARIC) study recruited 15,792 cohort participants aged 45 to 64 years in the period 1987 to 1989 from four communities. Hospitalization records obtained through cohort report and hospital record abstraction were matched to Medicare inpatient records (MedPAR) from 2006 to 2011. Factors associated with concordance were assessed graphically and using multinomial logit regression. RESULTS: Among fee-for-service enrollees, MedPAR and ARIC hospitalizations matched approximately 67% of the time. For Medicare Advantage enrollees, completeness increased after initiation of hospital financial incentives in 2008 to submit shadow bills for Medicare Advantage enrollees. Concordance varied by geographic site, age, veteran status, proximity to death, study attrition, and whether hospitalizations were within ARIC catchment areas. CONCLUSIONS: ARIC and MedPAR records had good concordance among fee-for-service enrollees, but many hospitalizations were available from only one source. MedPAR hospital records may be missing for veterans or observation stays. Maintaining study participation increases stay completeness, but new sources such as electronic health records may be more efficient than surveillance for mobile elderly populations.

Identification of Heart Failure Events in Medicare Claims: The Atherosclerosis Risk in Communities (ARIC) Study.

BACKGROUND: We examined the accuracy of Medicare heart failure (HF) diagnostic codes in the identification of acute decompensated (ADHF and chronic stable (CSHF) HF. METHODS AND RESULTS: Hospitalizations were identified from medical discharge records for Atherosclerosis Risk in Communities (ARIC) study participants with linked Medicare Provider Analysis and Review (MedPAR) files for the years 2005-2009. The ARIC study classification of ADHF and CSHF, based on adjudicated review of medical records, was considered to be the criterion standard. A total 8,239 ARIC medical records and MedPAR records meeting fee-for-service (FFS) criteria matched on unique participant ID and date of discharge (68.5% match). Agreement between HF diagnostic codes from the 2 data sources found in the matched records for codes in any position (κ > 0.9) was attenuated for primary diagnostic codes (κ < 0.8). Sensitivity of HF diagnostic codes found in Medicare claims in the identification of ADHF and CSHF was low, especially for the primary diagnostic codes. CONCLUSION: Matching of hospitalizations from Medicare claims with those obtained from abstracted medical records is incomplete, even for hospitalizations meeting FFS criteria. Within matched records, HF diagnostic codes from Medicare show excellent agreement with HF diagnostic codes obtained from medical record abstraction. The Medicare data may, however, overestimate the occurrence of hospitalized ADHF or CSHF.

Psychometric Properties of the Four-Item Morisky Green Levine Medication Adherence Scale among Atherosclerosis Risk in Communities (ARIC) Study Participants.

OBJECTIVES: To evaluate the reliability and factorial validity of the four-item Morisky Green Levine Medication Adherence Scale (MGLS) among Atherosclerosis Risk in Communities (ARIC) Study participants. METHODS: We used the cross-sectional visit 5 data from the ARIC Study to assess the measurement properties of the MGLS. We measured the internal consistency using Cronbach α (where α > 0.70 is considered reliable for group-level measurement), the response frequency, and the inter item correlation. Factor analysis of the MGLS and five other adherence items in the survey was conducted using a polychoric correlation matrix to examine the dimensionality that underlies the MGLS. A vanishing tetrad test was conducted to assess conformity with an effect indicator model. RESULTS: Among the ARIC visit 5 participants, 6,261 (96%) responded to the MGLS and other questions related to medication adherence in the survey (mean age 76 ± 5 years, 59% women). The Cronbach α for the MGLS was 0.47. The inter-item correlations ranged from 0.11 to 0.26. In the factor analysis of the medication adherence survey questions, a three-factor solution was used. One factor captured the extent of nonadherence, whereas other factors focused on the reasons for nonadherence. The MGLS items spread out across the factors that reflect the extent of as well as the reasons for nonadherence. The results of the vanishing tetrad test indicated that the MGLS consists of items other than effect indicators (P < 0.0001). CONCLUSIONS: The low reliability together with the factor analysis findings imply that the MGLS may reflect causes as well as the extent of medication adherence. The findings suggest that the MGLS, as presently used, lacks consistency in an elderly population.

The relationship between violence in Northern Mexico and potentially avoidable hospitalizations in the USA-Mexico border region.

BACKGROUND: Substantial proportions of US residents in the USA-Mexico border region cross into Mexico for health care; increases in violence in northern Mexico may have affected this access. We quantified associations between violence in Mexico and decreases in access to care for border county residents. We also examined associations between border county residence and access. METHODS: We used hospital inpatient data for Arizona, California and Texas (2005-10) to estimate associations between homicide rates and the probability of hospitalization for ambulatory care sensitive (ACS) conditions. Hospitalizations for ACS conditions were compared with homicide rates in Mexican municipalities matched by patient residence. RESULTS: A 1 SD increase in the homicide rate of the nearest Mexican municipality was associated with a 2.2 percentage point increase in the probability of being hospitalized for an ACS condition for border county patients. Residence in a border county was associated with a 1.3 percentage point decrease in the probability of being hospitalized for an ACS condition. CONCLUSIONS: Increased homicide rates in Mexico were associated with increased hospitalizations for ACS conditions in the USA, although residence in a border county was associated with decreased probability of being hospitalized for an ACS condition. Expanding access in the border region may mitigate these effects by providing alternative sources of care.

Assessing Medicare Part D claim completeness using medication self-reports: the role of veteran status and Generic Drug Discount Programs.

OBJECTIVE: Medicare Part D claims are commonly used for research, but missing claims could compromise their validity. This study assessed 2 possible causes of missing claims: veteran status and Generic Drug Discount Programs (GDDP). MATERIALS AND METHODS: We merged medication self-reports from telephone interviews in the Atherosclerosis Risk in Communities (ARIC) Study with Part D claims for 6 medications (3 were commonly in GDDP in 2009). Merged records (4468) were available for 2905 ARIC participants enrolled in Part D. Multinomial logit regression provided estimates of the association of concordance (self-report and Part D, self-report only, or Part D only) with veteran and GDDP status, controlling for participant sociodemographics. RESULTS: Sample participants were 74±5 years of age, 68% white and 63% female; 19% were male veterans. Compared with females, male veterans were 11% [95% confidence interval (CI), 7%-16%] less likely to have matched medications in self-report and Part D and 11% (95% CI, 7%-16%) more likely to have self-report only. Records for GDDP versus non-GDDP medications were 4% (95% CI, 1%-7%) more likely to be in self-report and Part D and 3% (95% CI, 1%-5%) less likely to be in Part D only, with no difference in self-report only. CONCLUSIONS: Part D claims were more likely to be missing for veterans, but claims for medications commonly available through GDDP were more likely to match with self-reports. Although researchers should be aware of the possibility of missing claims, GDDP status was associated with a higher rather than lower likelihood of claims being complete in 2009.

Informal care and caregiver's health.

This study aims to measure the causal effect of informal caregiving on the health and health care use of women who are caregivers, using instrumental variables. We use data from South Korea, where daughters and daughters-in-law are the prevalent source of caregivers for frail elderly parents and parents-in-law. A key insight of our instrumental variable approach is that having a parent-in-law with functional limitations increases the probability of providing informal care to that parent-in-law, but a parent-in-law's functional limitation does not directly affect the daughter-in-law's health. We compare results for the daughter-in-law and daughter samples to check the assumption of the excludability of the instruments for the daughter sample. Our results show that providing informal care has significant adverse effects along multiple dimensions of health for daughter-in-law and daughter caregivers in South Korea.

Examining continuity of care for Medicaid-enrolled children receiving oral health services in medical offices.

Children living in poverty encounter barriers to dentist visits and disproportionally experience dental caries. To improve access, most state Medicaid programs reimburse pediatric primary care providers for delivering preventive oral health services. To understand continuity of oral health services for children utilizing the North Carolina (NC) Into the Mouths of Babes (IMB) preventive oral health program, we examined the time to a dentist visit after a child's third birthday. This retrospective cohort study used NC Medicaid claims from 2000 to 2006 for 95,578 Medicaid-enrolled children who received oral health services before age 3. We compared children having only dentist visits before age 3 to those with: (1) only IMB visits and (2) both IMB and dentist visits. Cox proportional hazards regression was used to estimate the time to a dentist visit following a child's third birthday. Propensity scores with inverse-probability-of-treatment-weights were used to address confounding. Children with only IMB visits compared to only dentist visits before age 3 had lower rates of dentist visits after their third birthday [adjusted hazard ratio (AHR) = 0.41, 95 % confidence interval (CI) 0.39-0.43]. No difference was observed for children having both IMB and dentist visits and only dentist visits (AHR = 0.99, 95 % CI 0.96-1.03). Barriers to dental care remain as children age, hindering continuity of care for children receiving oral health services in medical offices.

Trajectory of overall health from self-report and factors contributing to health declines among cancer survivors.

PURPOSE: This study aims to quantify trajectories of overall health pre- and post-diagnosis of cancer, trajectories of overall health among cancer-free individuals, and factors affecting overall health status. METHODS: Overall health status, derived from self-rated health report, of Atherosclerosis Risk in Communities cohort participants diagnosed with incident cancer [lung (n = 400), breast (n = 522), prostate (n = 615), colorectal (n = 303)], and cancer-free participants (n = 11,634) over 19 years was examined. Overall health was evaluated in two ways: (1) overall health was assessed until death or follow-up year 19 (survivorship model) and (2) same as survivorship model except that a self-rated health value of zero was used for assessments after death to follow-up year 19 (cohort model). Mean overall health at discrete times was used to generate overall health trajectories. Differences in repeated measures of overall health were assessed using linear growth models. RESULTS: Overall health trajectories declined dramatically within one-year of cancer diagnosis. Lung, breast, and colorectal cancer were associated with a significant decreased overall health score (ß) compared to the cancer-free group (survivorship model: lung-7.00, breast-3.97, colorectal-2.12; cohort model: lung-7.63, breast-5.07, colorectal-2.30). Other predictors of decreased overall health score included low education, diabetes, cardiovascular disease, and age. CONCLUSIONS: All incident cancer groups had declines in overall health during the first year post-diagnosis, which could be due to cancer diagnosis or intensive treatments. Targeting factors related to overall health declines could improve health outcomes for cancer patients.

Anger proneness, gender, and the risk of heart failure.

BACKGROUND: Evidence regarding the association of anger proneness with incidence of heart failure is lacking. METHODS AND RESULTS: Anger proneness was ascertained among 13,171 black and white participants of the Atherosclerosis Risk in Communities (ARIC) study cohort with the use of the Spielberger Trait Anger Scale. Incident heart failure events, defined as occurrence of ICD-9-CM code 428.x, were ascertained from participants' medical records during follow-up in the years 1990-2010. Relative hazard of heart failure across categories of trait anger was estimated with the use of Cox proportional hazard models. Study participants (mean age 56.9 [SD 5.7] years) experienced 1,985 incident HF events during 18.5 (SD 4.9) years of follow-up. Incidence of HF was greater among those with high, as compared to those with low or moderate trait anger, with higher incidence observed for men than for women. The relative hazard of incident HF was modestly high among those with high trait anger, compared with those with low or moderate trait anger (age-adjusted hazard ratio for men: 1.44 (95% confidence interval [CI] 1.23-1.69). Adjustment for comorbidities and depressive symptoms attenuated the estimated age-adjusted relative hazard in men to 1.26 (95% CI 1.00-1.60). CONCLUSIONS: Assessment of anger proneness may be necessary in successful prevention and clinical management of heart failure, especially in men.

Explaining variation in hospice visit intensity for routine home care.

BACKGROUND: Medicare pays a flat per diem rate by level of hospice service without case-mix adjustment, although previous research shows that visit intensity varies considerably over the course of hospice episodes. Concerns pertain to the inherent financial incentives for routine home care, the most frequently used level, and whether payment efficiency can be improved using case-mix adjustment. OBJECTIVES: The aim of this study was to assess variation in hospice visit intensity during hospice episodes by patient, hospice, and episode characteristics to inform policy discussions regarding hospice payment methods. RESEARCH DESIGN: This observational study used Medicare claims for hospice episodes in 2010. Multiple observations were constructed per episode phase (eg, days 1-14, 15-30, etc.). Episode phase and observed characteristics were regressed on average routine home care visit intensity per day; patient and hospice fixed effects controlled for unobserved characteristics. MEASURES: Visit intensity was constructed using national wages to weight visits by provider type. Observed patient characteristics included age, sex, race, diagnoses, venue of care, use of other hospice levels of care, and discharge status; hospice characteristics included ownership, affiliation, size, and urban/state location. RESULTS: Visit intensity varied substantially by episode phase. This pattern was largely invariant to observed patient and hospice characteristics, which explained <4% of variation in visit intensity per day after adjusting for episode phase. Unobserved patient characteristics explained approximately 85% of remaining variation. CONCLUSIONS: These results show that case-mix adjustment based on commonly observed factors would only minimally improve hospice payment methodology.

Effects of early dental office visits on dental caries experience.

OBJECTIVES: We determined the association between timing of a first dentist office visit before age 5 years and dental disease in kindergarten. METHODS: We used North Carolina Medicaid claims (1999-2006) linked to state oral health surveillance data to compare caries experience for kindergarten students (2005-2006) who had a visit before age 60 months (n=11,394) to derive overall exposure effects from a zero-inflated negative binomial regression model. We repeated the analysis separately for children who had preventive and tertiary visits. RESULTS: Children who had a visit at age 37 to 48 and 49 to 60 months had significantly less disease than children with a visit by age 24 months (incidence rate ratio [IRR]=0.88; 95% confidence interval [CI]=0.81, 0.95; IRR=0.75; 95% CI=0.69, 0.82, respectively). Disease status did not differ between children who had a tertiary visit by age 24 months and other children. CONCLUSIONS: Medicaid-enrolled children in our study followed an urgent care type of utilization, and access to dental care was limited. Children at high risk for dental disease should be given priority for a preventive dental visit before age 3 years.

Comparing medical and dental providers of oral health services on early dental caries experience.

OBJECTIVES: Most state Medicaid programs reimburse nondental primary care providers (PCPs) for providing preventive oral health services to young children. We examined the association between who (PCP, dentist, or both) provides these services to Medicaid enrollees before age 3 years and oral health at age 5 years. METHODS: We linked North Carolina Medicaid claims (1999-2006) to oral health surveillance data (2005-2006). Regression models estimated oral health status (number of decayed, missing, and filled primary teeth) and untreated disease (proportion of untreated decayed teeth), with adjustment for relevant characteristics and by using inverse-probability-of-treatment weights to address confounding. RESULTS: We analyzed data for 5235 children with 2 or more oral health visits from a PCP, dentist, or both. Children with multiple PCP or dentist visits had a similar number of overall mean decayed, missing, and filled primary teeth in kindergarten, whereas children with only PCP visits had a higher proportion of untreated decayed teeth. CONCLUSIONS: The setting and provider type did not influence the effectiveness of preventive oral health services on children's overall oral health. However, children having only PCP visits may encounter barriers to obtaining dental treatment.
