Inter-clinician eConsults without programmatic incentives or requirements: a qualitative study of primary care provider perspectives.

BACKGROUND: Inter-clinician electronic consultation (eConsult) programmes are becoming more widespread in the USA as health care systems seek innovative ways of improving specialty access. Existing studies examine models with programmatic incentives or requirements for primary care providers (PCPs) to participate. OBJECTIVE: We aimed to examine PCP perspectives on eConsults in a system with no programmatic incentive or requirement for PCPs to use eConsults. METHODS: We conducted seven focus groups with 41 PCPs at a safety-net community teaching health care system in Eastern Massachusetts, USA. RESULTS: Focus groups revealed that eConsults improved PCP experience by enabling patient-centred care and enhanced PCP education. However, increased workload and variations in communication patterns added challenges for PCPs. Patients were perceived as receiving timelier and more convenient care. Timelier care combined with direct documentation in the patient record was perceived as improving patient safety. Although cost implications were less clear, PCPs perceived costs as being lowered through fewer unnecessary visits and laboratories. CONCLUSIONS: Our findings suggest that eConsult systems with no programmatic incentives or requirements for PCPs have the potential to improve care.

Experiences applying for and understanding health insurance under Massachusetts health care reform.

BACKGROUND: The Affordable Care Act was modeled on the Massachusetts Health Reform of 2006, which reduced the number of uninsured largely through a Medicaid expansion and the provision of publicly subsidized insurance obtained through a Health Benefits Exchange. METHODS: We surveyed a convenience sample of 780 patients seeking care in a safety-net system who obtained Medicaid or publicly subsidized insurance after the Massachusetts reform, as well as a group of employed patients with private insurance. RESULTS: We found that although most patients with Medicaid or publicly subsidized exchange-based plans were able to obtain assistance with applying for and choosing an insurance plan, substantial proportions of respondents experienced difficulties with the application process and with understanding coverage and cost features of plans. CONCLUSIONS: Under the Affordable Care Act, efforts to simplify the application process and reduce the complexity of plans may be warranted, particularly for vulnerable patient populations cared for by the medical safety net.

Support for National Health Insurance Seven Years Into Massachusetts Healthcare Reform: Views of Populations Targeted by the Reform.

Before the Affordable Care Act (ACA), many surveys showed majority support for national health insurance (NHI), also known as single payer; however, little is currently known about views of the ACA's targeted population. Massachusetts residents have had seven years of experience with state health care reform that became the model for the ACA. We surveyed 1,151 adults visiting safety-net emergency departments in Massachusetts in late 2013 on their preference for NHI or the Massachusetts reform and on their experiences with insurance. Most of the patients surveyed were low-income and non-white. The majority of patients (72.0%) preferred NHI to the Massachusetts reform. Support for NHI among those with public insurance, commercial insurance, and no insurance was 68.9%, 70.3%, and 86.3%, respectively (p < .001). Support for NHI was higher among patients dissatisfied with their insurance plan (83.3% vs. 68.9%, p = .014), who delayed medical care (81.2% vs. 69.6%, p < .001) or avoided purchasing medications due to cost (87.3% vs. 71.4%; p = .01). Majority support for NHI was observed in every demographic subgroup. Given the strong support for NHI among disadvantaged Massachusetts patients seven years after state health reform, a reappraisal of the ACA's ability to meet the needs of underserved patients is warranted.

Perceived affordability of health insurance and medical financial burdens five years in to Massachusetts health reform.

INTRODUCTION: Under the Massachusetts health reform, low income residents (those with incomes below 150 % of the Federal Poverty Level [FPL]) were eligible for Medicaid and health insurance exchange-based plans with minimal cost-sharing and no premiums. Those with slightly higher incomes (150 %-300 % FPL) were eligible for exchange-based plans that required cost-sharing and premium payments. METHODS: We conducted face to face surveys in four languages with a convenience sample of 976 patients seeking care at three hospital emergency departments five years after Massachusetts reform. We compared perceived affordability of insurance, financial burden, and satisfaction among low cost sharing plan recipients (recipients of Medicaid and insurance exchange-based plans with minimal cost-sharing and no premiums), high cost sharing plan recipients (recipients of exchange-based plans that required cost-sharing and premium payments) and the commercially insured. RESULTS: We found that despite having higher incomes, higher cost-sharing plan recipients were less satisfied with their insurance plans and perceived more difficulty affording their insurance than those with low cost-sharing plans. Higher cost-sharing plan recipients also reported more difficulty affording medical and non-medical health care as well as insurance premiums than those with commercial insurance. In contrast, patients with low cost-sharing public plans reported higher plan satisfaction and less financial concern than the commercially insured. CONCLUSIONS: Policy makers with responsibility for the benefit design of public insurance available under health care reforms in the U.S. should calibrate cost-sharing to income level so as to minimize difficulty affording care and financial burdens.

Affordability of health care under publicly subsidized insurance after Massachusetts health care reform: a qualitative study of safety net patients.

INTRODUCTION: The Affordable Care Act (ACA) and the 2006 Massachusetts (MA) health reform law, on which the ACA was based, aimed to improve the affordability of care largely by expanding publicly sponsored insurances. Both laws also aimed to promote consumer understanding of how to acquire, maintain and use these public plans. A prior study found an association between the level of cost-sharing required in these plans and the affordability of care. Preparatory to a quantitative study we conducted this qualitative study that aimed to examine (1) whether cost sharing levels built into the public insurance types that formed the backbone of the MA health reform led to unaffordability of care and if so, (2) how insurances with higher cost sharing levels led to unaffordability of care in this context. METHODS: We interviewed 12 consumers obtaining the most commonly obtained insurances under MA health reform (Medicaid and Commonwealth Care) at a safety net hospital emergency department. We purposefully interviewed a stratified sample of higher and low cost sharing recipients. We used a combination of inductive and deductive codes to analyze the data according to degree of cost-sharing required by different insurance types. RESULTS: We found that higher cost sharing plans led to unaffordability of care, as evidenced by unmet medical needs, difficulty affording basic non-medical needs due to expenditures on medical care, and reliance on non-insurance resources to pay for care. Participants described two principal mechanisms by which higher cost sharing led to unaffordability of care: (1) cost sharing above what their incomes allowed and (2) poor understanding of how to effectively acquire, maintain and utilize insurance new public plans. CONCLUSIONS: Further efforts to investigate the relationship between perceived affordability of care and understanding of insurance for the insurance types obtained under MA health reform may be warranted. A potential focus for further work may be quantitative investigation of how the level of calibration of cost-sharing to income and understanding of insurances under the MA reform was associated with perceived affordability of care.

Infective endocarditis in the U.S., 1998-2009: a nationwide study.

BACKGROUND: Previous studies based on local case series estimated the annual incidence of endocarditis in the U.S. at about 4 per 100,000 population. Small-scale studies elsewhere have reported similar incidence rates. However, no nationally-representative population-based studies have verified these estimates. METHODS AND FINDINGS: Using the 1998-2009 Nationwide Inpatient Sample, which provides diagnoses from about 8 million U.S. hospitalizations annually, we examined endocarditis hospitalizations, bacteriology, co-morbidities, outcomes and costs. Hospital admissions for endocarditis rose from 25,511 in 1998 to 38, 976 in 2009 (12.7 per 100,000 population in 2009). The age-adjusted endocarditis admission rate increased 2.4% annually. The proportion of patients with intra-cardiac devices rose from 13.3% to 18.9%, while the share with drug use and/or HIV fell. Mortality remained stable at about 14.5%, as did cardiac valve replacement (9.6%). Other serious complications increased; 13.3% of patients in 2009 suffered a stroke or CNS infection, and 5.5% suffered myocardial infarction. Amongst cases with identified pathogens, Staphylococcus aureus was the most common, increasing from 37.6% in 1998 to 49.3% in 2009, 53.3% of which were MRSA. Streptococci were mentioned in 24.7% of cases, gram-negatives in 5.6% and Candida species in 1.0%. We detected no inflection in hospitalization rates after changes in prophylaxis recommendations in 2007. Mean age rose from 58.6 to 60.8 years; elderly patients suffered higher rates of myocardial infarction and death, but slightly lower rates of Staphylococcus aureus infections and neurologic complications. Our study relied on clinically diagnosed cases of endocarditis that may not meet strict criteria. Moreover, since some patients are discharged and readmitted during a single episode of endocarditis, our hospitalization figures probably slightly overstate the true incidence of this illness. CONCLUSIONS: Endocarditis is more common in the U.S. than previously believed, and is steadily increasing. Preventive efforts should focus on device-associated and health-care-associated infections.

Access to care after Massachusetts' health care reform: a safety net hospital patient survey.

BACKGROUND: Massachusetts' health care reform substantially decreased the percentage of uninsured residents. However, less is known about how reform affected access to care, especially according to insurance type. OBJECTIVE: To assess access to care in Massachusetts after implementation of health care reform, based on insurance status and type. DESIGN AND PARTICIPANTS: We surveyed a convenience sample of 431 patients presenting to the Emergency Department of Massachusetts' second largest safety net hospital between July 25, 2009 and March 20, 2010. MAIN MEASURES: Demographic and clinical characteristics, insurance coverage, measures of access to care and cost-related barriers to care. KEY RESULTS: Patients with Commonwealth Care and Medicaid, the two forms of insurance most often newly-acquired under the reform, reported similar or higher utilization of and access to outpatient visits and rates of having a usual source of care, compared with the privately insured. Compared with the privately insured, a significantly higher proportion of patients with Medicaid or Commonwealth Care Type 1 (minimal cost sharing) reported delaying or not getting dental care (42.2 % vs. 27.1 %) or medication (30.0 % vs. 7.0 %) due to cost; those with Medicaid also experienced cost-related barriers to seeing a specialist (14.6 % vs. 3.5 %) or getting recommended tests (15.6 % vs. 5.9 %). Those with Commonwealth Care Types 2 and 3 (greater cost sharing) reported significantly more cost-related barriers to obtaining care than the privately insured (45.0 % vs. 16.0 %), to seeing a primary care doctor (25.0 % vs. 6.0 %) or dental provider (58.3 % vs. 27.1 %), and to obtaining medication (20.8 % vs. 7.0 %). No differences in cost-related barriers to preventive care were found between the privately and publicly insured. CONCLUSIONS: Access to care improved less than access to insurance following Massachusetts' health care reform. Many newly insured residents obtained Medicaid or state subsidized private insurance; cost-related barriers to access were worse for these patients than for the privately insured.

Reasons why patients remain uninsured after Massachusetts' health care reform: a survey of patients at a safety-net hospital.

BACKGROUND: Following the 2006 Massachusetts health care reform, an estimated 316,492 residents remain uninsured. However, there have been no published studies that examine why Massachusetts residents remain uninsured four years into health reform. OBJECTIVE: To describe the characteristics of uninsured patients seeking acute medical care in Massachusetts after implementation of health care reform and reasons for lacking insurance. DESIGN AND PARTICIPANTS: We performed an in-person survey of a convenience sample of patients visiting the emergency department of the state's second largest safety net hospital between July 25, 2009 and March 20, 2010. We interviewed 431 patients age 18-64, 189 of whom were uninsured. MAIN MEASURES: Demographic and clinical characteristics, employment and insurance history, reasons for lacking insurance and views of the state's new "individual mandate". KEY RESULTS: The uninsured were largely employed (65.9%), but only a quarter (25.1%) of the employed uninsured had access to employer-sponsored insurance. The majority qualified for subsidized insurance (85.7% earned ≤ 300% of the federal poverty level), yet many reported being unable to find affordable insurance (32.7%). Over a third (35.2%) were uninsured because they had lost insurance due predominantly to job loss or policy cancellation. For nearly half of the uninsured (48.6%), the individual mandate had motivated them to try to find insurance, but they were unable to find insurance they could afford. CONCLUSIONS: After full implementation of the Massachusetts health reform, those remaining without insurance are largely the working poor who do not have access to, or cannot afford, either employer sponsored insurance or state subsidized insurance.

Foot temperature in healthy individuals: effects of ambient temperature and age.

BACKGROUND: Patient complaints of excessively warm or cold feet are common in medical practice. Such symptoms can be caused by underlying vascular or neurologic disease, and measurement of foot temperature during daily activity and sleep could provide a deeper understanding of their actual thermal basis. METHODS: We used a Thermochron iButton to assess surface foot temperature variation and its relationship to ambient temperature during the day with activity and at night during sleep in 39 healthy individuals aged 18 to 65 years in a temperate region of the United States. We simultaneously used actigraphy to record leg movement. RESULTS: We identified a mean +/- SD awake temperature of 30.6 degrees +/- 2.6 degrees C and asleep temperature of 34.0 degrees +/- 1.8 degrees C, with values reaching as low as 15.9 degrees C in the winter and as high as 37.5 degrees C in the summer. Foot temperature was found to be independent of foot movement or sex; however, there was, as expected, a strong association between foot temperature and ambient temperature (r = .59, P < .001). Several measures of foot temperature variation demonstrated a significant or near-significant reduction with increasing age, including the Euclidean distance (r = -.38, P = .02) for awake periods and the variance (r = -.30, P = .06) during sleep. CONCLUSIONS: These results provide data on the normal variation of foot temperature in individuals living in a temperate climate and demonstrate the potential use of Thermochron iButton technology in clinical contexts, including the evaluation of patients with excessively warm or cold feet.

Impact of insurance status on migraine care in the United States: a population-based study.

OBJECTIVE: To determine whether insurance status is associated with differential outpatient treatment of migraine in the United States. METHODS: We analyzed 11 years of data from the National Ambulatory Medical Care Survey and National Hospital Ambulatory Medical Care Survey (1997-2007), which survey patient visits to doctors' offices, hospital outpatient departments, and emergency departments (EDs) in the United States. We used logistic regression to determine whether insurance status was associated with the prescription of standard migraine therapy, defined as 1) a triptan or dihydroergotamine and 2) a prophylactic agent. RESULTS: We identified 6,814 individual patient visits for migraine, representing 68.6 million visits nationally. After controlling for age, gender, race/ethnicity, geographic location, and year, migraineurs with no insurance or Medicaid were less likely than the privately insured to receive abortive therapy (odds ratio [OR] for failure to receive medication 2.0 [95% confidence interval (CI) 1.3, 3.0] and 1.6 [95% CI 1.1, 2.3]) and prophylactic therapy (OR 2.0 [95% CI 1.3, 2.9] and 1.5 [95% CI 1.0, 2.1]). Adding site of care to the regression model suggested that one mechanism for this discrepancy was the reliance of the uninsured on EDs for migraine care, a site where standard migraine care is often omitted (OR for failure to receive abortive and prophylactic medication in the ED relative to physicians' offices 4.8 [95% CI 3.6, 6.3] and 8.7 [95% CI 6.4, 11.7]). CONCLUSIONS: The uninsured, and those with Medicaid, receive substandard therapy for migraine, at least in part because they receive more care in emergency departments and less in physicians' offices.

Clinical utility of electrodiagnostic studies in the inpatient setting.

Although nerve conduction studies/electromyograms are often requested to evaluate hospitalized patients (inpatients) with suspected neuromuscular diseases, their clinical utility has not been studied. They can be technically challenging, especially in intensive care units. We studied the contribution of inpatient electromyograms (IP-EMGs) to the management of patients with suspected neuromuscular disorders. A total of 103 IP-EMGs in 98 patients were analyzed. IP-EMGs confirmed the clinical diagnosis in 53.3% and provided a new, clinically relevant diagnosis in 12.6%. IP-EMGs revealed only an incidental diagnosis in 14.5%, were inconclusive in 16.5%, and were normal in 3%. In over a quarter of patients, IP-EMGs assisted in planning further diagnostic evaluation or treatment. Although IP-EMGs most often only confirm already suspected diagnoses, in a substantial minority of patients they lead to the identification of clinically unsuspected, significant diagnoses that alter subsequent clinical care.

Effect of newly proposed CK reference limits on neuromuscular diagnosis.

The objective was to determine the effect of a proposed increase in the upper reference limits of serum creatine kinase (CK) on neuromuscular disease diagnosis. This was a retrospective study of 94 Caucasian subjects (49 women and 45 men) in whom a neuromuscular physician ordered a CK as part of their evaluation. The patients were divided into two groups: those with diagnoses that either should or could elevate serum CK, and those with diagnoses that should not elevate serum CK. Sensitivities and specificities of the manufacturer's and the newly proposed upper reference limits were determined. For women, raising the upper reference limit of CK from 140 IU/L to 201 IU/L reduced the sensitivity of the test from 50% to 29%, while increasing the specificity from 67% to 80%. For men, raising the upper reference limit of CK from 174 IU/L to 322 IU/L reduced the sensitivity from 80% to 60%, while increasing the specificity from 63% to 80%. The newly proposed upper reference limits resulted in a false-negative CK of clinical significance in 7 of 94 subjects. Increasing the upper reference limit for CK reduced the sensitivity and increased the specificity of serum CK for neuromuscular disease diagnosis. Such a change will reduce unnecessary referrals and invasive diagnostic testing in patients with asymptomatic CK elevations. The clinical impact of the loss in sensitivity is small. If these new upper reference limits are adopted, neuromuscular physicians should be aware that a normal CK level does not exclude a diagnosis of myopathy.

Impaired distal thermoregulation in diabetes and diabetic polyneuropathy.

OBJECTIVE: To determine how thermoregulation of the feet is affected by diabetes and diabetic polyneuropathy in both wakefulness and sleep. RESEARCH DESIGN AND METHODS: Normal subjects, diabetic subjects without neuropathy, diabetic subjects with small-fiber diabetic polyneuropathy, and those with advanced diabetic polyneuropathy were categorized based on neurological examination, nerve conduction studies, and quantitative sensory testing. Subjects underwent foot temperature monitoring using an iButton device attached to the foot and a second iButton for recording of ambient temperature. Socks and footwear were standardized, and subjects maintained an activity diary. Data were collected over a 32-h period and analyzed. RESULTS: A total of 39 normal subjects, 28 patients with diabetes but without diabetic polyneuropathy, 14 patients with isolated small-fiber diabetic polyneuropathy, and 27 patients with more advanced diabetic polyneuropathy participated. No consistent differences in foot temperature regulation between the four groups were identified during wakefulness. During sleep, however, multiple metrics revealed significant abnormalities in the diabetic patients. These included reduced mean foot temperature (P < 0.001), reduced maximal temperature (P < 0.001), increased rate of cooling (P < 0.001), as well as increased frequency of variation (P = 0.005), supporting that patients with diabetic polyneuropathy and even those with only diabetes but no diabetic polyneuropathy have impaired nocturnal thermoregulation. CONCLUSIONS: Nocturnal foot thermoregulation is impaired in patients with diabetes and diabetic polyneuropathy. Because neurons are highly temperature sensitive and because foot warming is part of the normal biology of sleep onset and maintenance, these findings suggest new potentially treatable mechanisms of diabetes-associated nocturnal pain and sleep disturbance.
