Effects of Practice Ownership and Integration of Health Services on Adherence to Diabetes Guidelines.

OBJECTIVE: There has been a trend toward hospital systems and insurers acquiring privately owned physician practices and subsequently converting them into vertically integrated practices. The purpose of this study is to observe whether this change in ownership of a medical practice influences adherence to clinical guidelines for the management of type 1 and type 2 diabetes. METHODS: This is an observational study using pooled cross-sectional data (2014-2016 and 2018-2019) from the National Ambulatory Medical Care Survey, a nationally representative probability sample of US office-based physician visits. A total of 7499 chronic routine follow ups and preventative care visits to non-integrated (solo and group physician practices) and integrated practices were analyzed to see whether guideline concordant care was provided. Measures included 7 services that are recommended annually for individuals with type 1 and type 2 diabetes (HbA1c, lipid panel, serum creatinine, depression screening, influenza immunization, foot examination, and BMI). RESULTS: Compared to non-integrated physician practices, vertically integrated practices had higher rates of hemoglobin A1C testing (odds ratio 1.58 [95% CI 1.07-2.33], P < .05), serum creatine testing (odds ratio 1.53 [95% CI 1.02-2.29], P < .05), foot examinations (odds ratio 2.03 [95% CI 0.98-4.22], P = .058), and BMI measuring (odds ratio 1.54 [95% CI 0.99-2.39], P = .054). There was no significant difference in lipid panel testing, depression screenings, or influenza immunizations. CONCLUSIONS: Our results show that integrated medical practices have a higher adherence to diabetes practice guidelines than non-integrated practices. However, rates of services provided regardless of ownership were low.

Racial and Ethnic Disparities in Emergency Department Wait Times for Headache.

Headache is a common complaint of individuals seeking treatment in the emergency department (ED). Because pain is subjective, medical evaluation is susceptible to implicit bias that can lead to disparities in wait times. The aim of this study was to determine whether there are racial and ethnic disparities in ED wait times for headache. Our study used the 2015-2018 National Hospital Ambulatory Care Surveys (NHAMCS), a nationally representative sample of ambulatory care visits to EDs. Our sample consisted of visits made by adults for headaches, which were identified using ICD-10 diagnosis codes and NHAMCS reason for visit codes. There were 12,301,655 ED visits for headache represented by our sample. The mean wait time for headache visits was 38.1 min (95%CI: 31.1, 45.0). The mean wait time for Non-Hispanic White patients, non-Hispanic Black patients, Hispanic patients, and the other race and ethnicity groups were 34.7 min (95%CI: 27.5, 42.0), 46.4 min (95%CI: 26.5, 66.4), 37.9 min (95%CI: 19.4, 56.3), and 21.0 min (95%CI: 6.3, 35.7) respectively. After controlling for patient- and hospital-level covariates, visits by non-Hispanic Black patients had 40% (95%CI: -0.01, 0.81, p = 0.056) longer wait times and visits by Hispanic patients had 39% (95%CI: -0.03, 0.80, p = 0.068) longer wait times than visits by non-Hispanic White patients. While our findings suggest that there may be longer wait times for visits by non-Hispanic Black and Hispanic patients compared to visits by non-Hispanic White patients, further research is needed to confirm these findings and determine causes of wait times disparities in the ED.

Racial inequities in emergency department wait times for pregnancy-related concerns.

OBJECTIVE: Emergency department care is common among US pregnant women. Given the increased likelihood of serious and life-threatening pregnancy-related health conditions among Black mothers, timeliness of emergency department care is vital. The objective of this study was to evaluate racial/ethnic variations in emergency department wait times for receiving obstetrical care among a nationally representative population. METHODS: The study used pooled 2016-2018 data from the National Hospital Ambulatory Medical Care Survey, a nationally representative sample of emergency department visits. Regression models were estimated to determine whether emergency department wait time was associated with the race/ethnicity of the perinatal patient. Adjusted models controlled for age, obesity status, insurance type, whether the patient arrived by ambulance, triage status, presence of a patient dashboard, and region. RESULTS: There were a total of 821 reported pregnancy-related visits in the National Hospital Ambulatory Medical Care Survey sample of emergency department visits. Of those 821 visits, 40.6% were among White women, 27.7% among Black women, and 27.5% among Hispanic women. Mean wait times differed substantially by race/ethnicity. After adjusting for potential confounders, Black women waited 46% longer than White women with emergency department visits for pregnancy problems (p < .05). Those reporting another race waited 95% longer for pregnancy problems in the emergency department than White women (p < .05). CONCLUSION: Findings from this study document significant racial/ethnic differences in wait times for perinatal emergency department care. Although inequities in wait times may emerge across the spectrum of care, documenting the factors influencing racial disparities in wait times are critical to promoting equitable perinatal health outcomes.

Service utilization in Medicaid HIV specialty plans versus standard plans among enrollees diagnosed with HIV/AIDS in Florida, U.S.A.

In the United States (U.S.), to contain costs many state Medicaid programs offer specialty health insurance plans for costly conditions such as HIV/AIDS. This study compared service utilization between Florida Medicaid enrollees diagnosed with HIV/AIDS in standard Medicaid managed care plans to enrollees in HIV/AIDS specialty plans. We found lower mean utilization among HIV/AIDS enrollees in specialty plans compared to enrollees with HIV/AIDS in standard MMA plans for all services except inpatient which was approximately the same. While fewer emergency visits is a desired outcome, lower rates of other services may indicate suboptimal management of patients or lower engagement in care among enrollees in HIV/AIDS specialty plans. Continuous monitoring of experiences of patients in HIV/AIDS specialty plans is warranted to determine whether the observed utilization patterns represent better management through reductions in low value care or reduced engagement in care, and whether these utilization patterns persist.

Impact of an Emergency Department-to-Home Transitional Care Intervention on Health Service Use in Medicare Beneficiaries: A Mixed Methods Study.

BACKGROUND: Hospital-based acute care [emergency department (ED) visits and hospitalizations] that is preventable with high-quality outpatient care contributes to health care system waste and patient harm. OBJECTIVE: To test the hypothesis that an ED-to-home transitional care intervention reduces hospital-based acute care in chronically ill, older ED visitors. RESEARCH DESIGN: Convergent, parallel, mixed-methods design including a randomized controlled trial. SETTING: Two diverse Florida EDs. SUBJECTS: Medicare fee-for-service beneficiaries with chronic illness presenting to the ED. INTERVENTION: The Coleman Care Transition Intervention adapted for ED visitors. MEASURES: The main outcome was hospital-based acute care within 60 days of index ED visit. We also assessed office-based outpatient visits during the same period. RESULTS: The Intervention did not significantly reduce return ED visits or hospitalizations or increase outpatient visits. In those with return ED visits, the Intervention Group was less likely to be hospitalized than the Usual Care Group. Interview themes describe a cycle of hospital-based acute care largely outside patients' control that may be difficult to interrupt with a coaching intervention. CONCLUSIONS AND RELEVANCE: Structural features of the health care system, including lack of access to timely outpatient care, funnel patients into the ED and hospital admission. Reducing hospital-based acute care requires increased focus on the health care system rather than patients' care-seeking decisions.

Factors associated with persistently high-cost health care utilization for musculoskeletal pain.

BACKGROUND: Musculoskeletal pain conditions incur high costs and produce significant personal and public health consequences, including disability and opioid-related mortality. Persistence of high-cost health care utilization for musculoskeletal pain may help identify system inefficiencies that could limit value of care. The objective of this study was to identify factors associated with persistent high-cost utilization among individuals seeking health care for musculoskeletal pain. METHODS: This was a retrospective cohort study of Medical Expenditure Panel Survey data (2008-2013) that included a non-institutionalized, population-based sample of individuals seeking health care for a musculoskeletal pain condition (n = 12,985). Expenditures associated with musculoskeletal pain conditions over two consecutive years were analyzed from prescribed medicine, office-based medical provider visits, outpatient department visits, emergency room visits, inpatient hospital stays, and home health visits. Persistent high-cost utilization was defined as being in the top 15th percentile for annual musculoskeletal pain-related expenditures over 2 consecutive years. We used multinomial regression to determine which modifiable and non-modifiable sociodemographic, health, and pain-related variables were associated with persistent high-cost utilization. RESULTS: Approximately 35% of direct costs for musculoskeletal pain were concentrated among the 4% defined as persistent high-cost utilizers. Non-modifiable variables associated with expenditure group classification included age, race, poverty level, geographic region, insurance status, diagnosis type and total number of musculoskeletal pain diagnoses. Modifiable variables associated with increased risk of high expenditure classification were higher number of missed work days, greater pain interference, and higher use of prescription medication for pain, while higher self-reported physical and mental health were associated with lower risk of high expenditure classification. CONCLUSIONS: Health care delivery models that prospectively identify these potentially modifiable factors may improve the costs and value of care for individuals with musculoskeletal pain prone to risk for high-cost care episodes.

Variation in out of pocket health care costs for individuals with anxiety disorders by type of insurance coverage.

PURPOSE: Given that out-of-pocket (OOP) costs impact adherence to treatment and recent and proposed changes to the health insurance system that impact OOP costs, it is imperative to understand the OOP cost burden faced by individuals with anxiety disorders depending upon type of insurance coverage. The objective of this study was to determine the annual OOP cost burden faced by individuals with anxiety disorders and the variation of these costs by type of insurance coverage. METHODS: Using weighted nationally representative data from the 2011-2014 Medical Expenditure Panel Surveys, total OOP health care costs were assessed for all respondents who indicated that they had an anxiety disorder (N = 9985). Total OOP health care costs were also calculated separately by type of insurance. RESULTS: Average annual OOP costs among individuals with anxiety was $1152. The highest OOP cost were incurred by individuals with private fee-for-service (FFS) insurance ($1356/year, 4.1% of annual income), while individuals enrolled in HMOs with dual Medicare/Medicaid had the lowest OOP cost ($129/year, 6.8% of annual income). Individuals without insurance had high OOP cost burden ($1309/year, 12.5% of annual income). CONCLUSION: Individuals with anxiety disorders have a wide range of OOP cost depending upon their insurance coverage. Those with anxiety should carefully consider their choice of insurance coverage if interested in minimizing OOP costs.

The impact of nurse practitioner regulations on population access to care.

BACKGROUND: By 2025, experts estimate a significant shortage of primary care providers in the United States, and expansion of the nurse practitioner (NP) workforce may reduce this burden. However, barriers imposed by state NP regulations could reduce access to primary care. PURPOSE: The objectives of this study were to examine the association between three levels of NP state practice regulation (independent, minimum restrictive, and most restrictive) and the proportion of the population with a greater than 30-min travel time to a primary care provider using geocoding. METHODS: Logistic regression models were conducted to calculate the adjusted odds of having a greater than 30-min drive time. FINDINGS: Compared with the most restrictive NP states, states with independent practice had 19.2% lower odds (p = .001) of a greater than 30-min drive to the closest primary care provider. DISCUSSION: Allowing NPs full autonomy to practice may be a relatively simple policy mechanism for states to improve access to primary care.

Sociodemographic Influences of Emergency Department Care for Anxiety Disorders.

This study examines variations in content of care for anxiety-related emergency department (ED) visits in the USA across various sociodemographic strata. The 2009-2012 National Hospital Ambulatory Medical Care Survey was used to identify all visits to general hospital EDs in which an anxiety diagnosis was recorded (n = 1930). Content and equitability of care was assessed utilizing logistic regression models. There were an estimated 1,856,000 ED visits with anxiety-related discharge diagnoses in the USA annually. Content of care and disposition varied by age, race/ethnicity, and insurance status. Visits by Medicaid patients were more likely than visits by privately insured patients to include a toxicology screen (OR = 1.67, p < .05) and visits by patients with either Medicaid or Medicare were less likely to include an EKG (OR = 0.53, p < .05 and OR = 0.52, p < .05, respectively). Understanding variations in ED care for anxiety can identify opportunities for intervention, both in the ED and upstream in appropriate healthcare settings.

Impacts of Initial Transformation to a Patient-Centered Medical Home on Diabetes Outcomes in Federally Qualified Health Centers in Florida.

OBJECTIVE: Federally qualified health centers (FQHCs) in Florida see large numbers of vulnerable patients with diabetes. Patient-centered medical home (PCMH) models can lead to improvements in health for patients with chronic conditions and cost savings for providers. Therefore, FQHCs are increasingly moving to PCMH models of care. The study objective was to examine the effects of initial transformation to a level 3 National Committee for Quality Assurance (NCQA) certified PCMH in 2011, on clinical diabetes outcomes among 27 clinic sites from a network of FQHCs in Florida. METHODS: We used de-identified, longitudinal electronic health record (EHR) data from 2010-2012 and multivariate logistic regression to analyze the effects of initial transformation on the odds of having well-controlled HbA1c, body mass index (BMI), and blood pressure (BP) among vulnerable patients with diabetes. Models controlled for clustering by year, patient, and organizational characteristics. RESULTS: Overall, transformation to a PCMH was associated with 19% greater odds of having well-controlled HbA1c values with no statistically significant impact on BMI or BP. Subanalyses showed transformation had less of an effect on BP for African American patients and HbA1c control for Medicare enrollees but a greater effect on weight control for patients older than 35 years. CONCLUSION: Transformation to a PCMH in FQHCs appears to improve the health of vulnerable patients with diabetes, with less improvement for subsets of patients. Future research should seek to understand the heterogeneous effects of patient-centered transformation on various subgroups.

Application of a Value Model for the Prevention and Management of Chronic Musculoskeletal Pain by Physical Therapists.

For physical therapists, establishing value of care is vitally important in the management of musculoskeletal pain. Value has become an important outcome measure in health care, largely as the result of payment reform efforts aimed at reducing wasteful spending. Providers who can establish the value of their services and be responsive to changing economic demands will be better positioned to deliver care. Establishing value is typically accomplished through comparative and cost-effectiveness studies. However, these approaches stop short of describing the components and processes that drive quality and costs-a necessary step for improving the value of existing services or developing new ones. The Institute of Medicine has recently called for more effective strategies to prevent and manage high-impact chronic pain. A model to guide the development and evaluation of pain management pathways will position physical therapists to best answer the Institute of Medicine's call within an increasingly value-focused health care environment. This perspective article presents a value model for physical therapy that describes how value emerges from interactions among the health care system, health care services organizations, the physical therapist, and the patient. How the model can be used to inform and guide the implementation of value-conscious treatment pathways for the prevention and management of chronic musculoskeletal pain also is discussed.

Clinical Outcomes, Utilization, and Charges in Persons With Neck Pain Receiving Guideline Adherent Physical Therapy.

In efforts to decrease practice variation, clinical practice guidelines for neck pain have been published. The purpose of this study was to determine the effect of receiving guideline adherent physical therapy (PT) on clinical outcomes, health care utilization, and charges for health care services in patients with neck pain. A retrospective review of 298 patients with neck pain receiving PT from 2008 to 2011 was performed. Clinical outcomes, utilization, and charges were compared between patients who received guideline adherent care and nonadherent care. Patients in the adherent care group experienced a lower percentage improvement in pain score compared to nonadherent care group (p = .01), but groups did not significantly differ on percentage improvement in disability (p = .32). However, patients receiving adherent care had an average 3.6 fewer PT visits (p < .001) and less charges for PT (p < .001). Additionally, patients receiving adherent care had 7.3 fewer visits to other health care providers (p < .001), one less prescription medication (p = .02) and 43% fewer diagnostic images (p = .02) but did not differ in their charges to other health care providers (p = .68) during the calendar year of undergoing PT. Although receiving guideline adherent care demonstrated positive effects on health care utilization and financial outcomes, there appears to be a trade-off with clinical outcomes.

Implications of practice setting on clinical outcomes and efficiency of care in the delivery of physical therapy services.

STUDY DESIGN: Retrospective analysis of episodes of care. OBJECTIVE: To assess the implications of practice setting (hospital outpatient settings versus private practice) on clinical outcomes and efficiency of care in the delivery of physical therapy services. BACKGROUND: Many patients with musculoskeletal conditions benefit from care provided by physical therapists. The majority of physical therapists deliver services in either a private practice setting or in a hospital outpatient setting. There have not been any recent studies comparing whether clinical outcomes or efficiency of care differ based on practice setting. METHODS: Practices that use the Focus On Therapeutic Outcomes, Inc system were surveyed to determine the specific type of setting in which outcomes were collected in patients with musculoskeletal impairments. Patient outcome data over 12 months (2011-2012) were extracted from the database and analyzed to identify differences in the functional status achieved and the efficiency of the care delivery process between private practices and hospital outpatient settings. RESULTS: The data suggest that patients experience more efficient care when receiving physical therapy in hospital outpatient settings compared to private practice settings, as demonstrated by 3.1 points of greater improvement in functional status over 2.9 fewer physical therapy visits. However, the difference in improvement between settings is less than the minimum clinically important difference of 9 points in functional status outcome score. CONCLUSION: In this cohort, our data suggest that more efficient care was delivered in the hospital outpatient setting compared to the private practice setting. However, we cannot conclude that care delivered in the hospital setting is more cost-effective, because it is possible that any difference in efficiency of care favoring the hospital outpatient setting is more than offset by higher costs of care.

Opioid prescribing by physicians with and without electronic health records.

BACKGROUND: Physicians in the U.S. are adopting electronic health records (EHRs) at an unprecedented rate. However, little is known about how EHR use relates to physicians' care decisions. Using nationally representative data, we estimated how using practice-based EHRs relates to opioid prescribing in primary care. METHODS: This study analyzed 33,090 visits to primary care physicians (PCPs) in the 2007-2010 National Ambulatory Medical Care Survey. We used logistic regression to compare opioid prescribing by PCPs with and without EHRs. RESULTS: Thirteen percent of all visits and 33 % of visits for chronic noncancer pain resulted in an opioid prescription. Compared to visits without EHRs, visits to physicians with EHRs had 1.38 times the odds of an opioid prescription (95 % CI, 1.22-1.56). Among visits for chronic noncancer pain, physicians with EHRs had significantly higher odds of an opioid prescription (adj. OR = 1.39; 95 % CI, 1.03-1.88). Chronic pain visits involving electronic clinical notes were also more likely to result in an opioid prescription compared to chronic pain visits without (adj. OR = 1.51; 95 % CI, 1.10-2.05). Chronic pain visits involving electronic test ordering were also more likely to result in an opioid prescription compared to chronic pain visits without (adj. OR = 1.31; 95 % CI, 1.01-1.71). CONCLUSIONS: We found higher levels of opioid prescribing among physicians with EHRs compared to those without. These results highlight the need to better understand how using EHR systems may influence physician prescribing behavior so that EHRs can be designed to reliably guide physicians toward high quality care.

Insurance status is associated with treatment allocation and outcomes after subarachnoid hemorrhage.

OBJECTIVE: Subarachnoid hemorrhage (SAH) is a particularly devastating type of stroke which is responsible for one third of all stroke-related years of potential life lost before age 65. Surgical treatment has been shown to decrease both morbidity and mortality after subarachnoid hemorrhage. We hypothesized that payer status other than private insurance is associated with lower allocation to surgical treatment for patients with SAH and worse outcomes. DESIGN: We examined the association between insurance type and surgical treatment allocation and outcomes for patients with SAH while adjusting for a wide range of patient and hospital factors. We analyzed the Nationwide Inpatient Sample hospital discharge database using survey procedures to produce weighted estimates representative of the United States population. PATIENTS: We studied 21047 discharges, representing a weighted estimate of 102595 patients age 18 and above with a discharge diagnosis of SAH between 2003 and 2008. MEASUREMENTS: Multivariable logistic and generalized linear regression analyses were used to assess for any associations between insurance status and surgery allocation and outcomes. MAIN RESULTS: Despite the benefits of surgery 66% of SAH patients did not undergo surgical treatment to prevent rebleeding. Mortality was more than twice as likely for patients with no surgical treatment compared to those who received surgery. Medicare patients were significantly less likely to receive surgical treatment. CONCLUSIONS: Nearly two thirds of patients with SAH don't receive operative care, and Medicare patients were significantly less likely to receive surgical treatment than other patients. Bias against the elderly and those with chronic illness and disability may play a part in these findings. A system of regionalized care for patients presenting with SAH may reduce disparities and improve appropriate allocation to surgical care and deserves prospective study.

Maternal morbidities and postpartum depression: an analysis using the 2007 and 2008 Pregnancy Risk Assessment Monitoring System.

PURPOSE: Postpartum depression (PPD) is common and associated with significant health outcomes and other consequences. Identifying persons at risk may improve screening and detection of PPD. This exploratory study sought to identify the morbidities that associate with 1) PPD symptoms and 2) PPD diagnosis. METHODS: Data from the 2007 and 2008 Pregnancy Risk Assessment Monitoring System were analyzed from 23 states and 1 city (n = 61,733 pregnancies); 13 antenatal morbidities were included. To determine whether antenatal morbidity predictors of PPD would differ based on PPD symptoms versus a diagnosis, each of the 13 antenatal morbidities were examined in separate logistic regression models with each PPD outcome. For each objective, two samples were examined: 1) Women from all states and 2) women from Alaska and Maine, the two states that included both PPD symptoms and PPD diagnosis measures in their questionnaires. Control variables included demographic and sociodemographic variables, pregnancy variables, antenatal and postpartum health behaviors, and birth outcomes. MAIN FINDINGS: Having vaginal bleeding (odds ratio [OR], 1.42; OR, 1.76), kidney/bladder infection (OR, 1.59; OR, 1.63), nausea (OR, 1.50; OR, 1.80), preterm labor (OR, 1.54; OR, 1.51), or being on bed rest (OR, 1.34; OR, 1.56) associated with both PPD symptoms and PPD diagnosis, respectively. Being in a car accident associated with PPD symptoms only (OR, 1.65), whereas having hypertension (OR, 1.94) or a blood transfusion (OR, 2.98) was associated with PPD diagnosis only. Among women from Alaska or Maine, having preterm labor (OR, 2.54, 2.11) or nausea (OR, 2.15, 1.60) was associated with both PPD symptoms and PPD diagnosis, respectively. Having vaginal bleeding (OR, 1.65), kidney/bladder infection (OR, 1.74), a blood transfusion (OR, 3.30), or being on bed rest (OR, 1.87) was associated with PPD symptoms only, whereas having diabetes before pregnancy (OR, 5.65) was associated with PPD diagnosis only. CONCLUSIONS: The findings of this exploratory study revealed differences in the antenatal morbidities that were associated with PPD symptoms versus diagnosis in both samples, and can assist prenatal care providers in prioritizing and screening for these morbidities that are associated with PPD during pregnancy. Additional research is warranted to confirm the results of this study in other samples and populations. Developing strategies to 1) improve general awareness of PPD and the appropriate antenatal morbidity risk factors to focus on in clinical settings, and 2) increase screening for the antenatal morbidities determined to be predictors of PPD in this study are warranted in preventing PPD.

How do high cost-sharing policies for physician care affect total care costs among people with chronic disease?

OBJECTIVE: This study examines whether high cost-sharing in physician care is associated with a differential impact on total care costs by health status. Total care includes physician care, emergency room (ER) visits and inpatient care. BACKGROUND: Since high cost-sharing policies can reduce needed care as well as unneeded care use, it raises the concern whether these policies are a good strategy for controlling costs among chronically ill patients. METHODS: This study used the 2007 Medical Expenditure Panel Survey data with a cross-sectional study design. Difference in difference (DID), instrumental variable technique, two-part model, and bootstrap technique were employed to analyze cost data. RESULTS: Chronically ill individuals' probability of reducing any overall care costs was significantly less than healthier individuals (beta = 2.18, p = 0.04), while the integrated DID estimator from split results indicated that going from low cost-sharing to high cost-sharing significantly reduced costs by $12,853.23 more for sick people than for healthy people (95% CI: -$17,582.86, -$8,123.60). CONCLUSIONS: This greater cost reduction in total care among sick people likely resulted from greater cost reduction in physician care, and may have come at the expense of jeopardizing health outcomes by depriving patients of needed care. Thus, these policies would be inappropriate in the short run, and unlikely in the long run to control health plans costs among chronically ill individuals. A generous benefit design with low cost-sharing policies in physician care or primary care is recommended for both health plans and chronically ill individuals, to save costs and protect these enrollees' health status.

Differences in patient ratings of medical home domains among adults with diabetes: comparisons across primary care sites.

BACKGROUND: There is growing and sustained recognition that Patient-Centered Medical Homes (PCMHs) represent a viable approach to dealing with the fragmentation of care faced by many individuals, including those living with diabetes. The National Committee for Quality Assurance (NCQA) has spearheaded a program that recognizes medical practices that adopt key elements of the PCMH. Even though practices can achieve the same level of recognition, it is unclear whether all PCMHs deliver care in the same manner and how these differences can be associated with patient ratings of their experience with care. METHODS: This study uses a mixed-methods approach to explore differences in care delivery across 4 NCQA level 3 recognized PCMHs located in a southern state. Furthermore, the study examines the association between each clinic and patient ratings of key PCMH domains. The qualitative component of the study included in-depth interviews with medical directors at each site in order to determine how the PCMH at each clinic was operationalized. In addition, 1300 adult patients with diabetes were surveyed about their experiences with their PCMH. Bivariate and ordinal logistical analyses were conducted to determine how PCMH experiences varied across the 4 clinics. RESULTS: The in-depth interviews revealed that one clinic (clinic 1) had a stronger primary care orientation relative to the other locations. Furthermore, patients at these clinics were more likely to provide higher ratings of care across all PCMH domains. CONCLUSIONS: This study demonstrates that not all PCMH clinics are alike and that these differences can possibly affect patient perceptions of their care.

Do provider service networks result in lower expenditures compared with HMOs or primary care case management in Florida's Medicaid program?

OBJECTIVE: To determine the impact of Florida's Medicaid Demonstration 4 years post-implementation on per member per month (PMPM) Medicaid expenditures and whether receiving care through HMOs versus provider service networks (PSNs) in the Demonstration was associated with PMPM expenditures. DATA: Florida Medicaid claims from two fiscal years prior to implementation of the Demonstration (FY0405, FY0506) and the first four fiscal years after implementation (FY0607-FY0910) from two urban Demonstration counties and two urban non-Demonstration counties. STUDY DESIGN: A difference-in-difference approach was used to compare changes in enrollee expenditures before and after implementation of the Demonstration overall and specifically for HMOs and PSNs. DATA EXTRACTION: Claims data were extracted for enrollees in the Demonstration and non-Demonstration counties and collapsed into monthly amounts (N = 26,819,987 person-months). PRINCIPAL FINDINGS: Among SSI enrollees, the Demonstration resulted in lower increases in PMPM expenditures over time ($40) compared with the non-Demonstration counties ($186), with Demonstration PSNs lowering PMPM expenditures by $7 more than HMOs. Savings were also seen among TANF enrollees but to a lesser extent. CONCLUSIONS: The Medicaid Demonstration in Florida appears to result in lower PMPM expenditures. Demonstration PSNs generated slightly greater reductions in expenditures compared to Demonstration HMOs. PSNs appear to be a promising model for delivering care to Medicaid enrollees.
