The role of managed care organizations in obesity management.

In the United States, obesity is characterized as this century's greatest healthcare threat. The American Medical Association and several other large organizations now classify obesity as a disease. Several federal initiatives are in the planning stages, have been approved, or are being implemented to address the disease. Obesity poses challenges for all healthcare stakeholders. Diet and exercise often are insufficient to create the magnitude of change patients and their attending healthcare providers need. Managed care organizations (MCOs) have 3 tools that can help their members: health and wellness programs focusing on lifestyle changes, prescription weight-loss drugs, and bariatric surgical interventions. MCOs are addressing changes with national requirements and are responding to the availability of new weight-loss drugs to help their members achieve better health. A number of factors either deter or stimulate the progress of weight loss therapy. Understanding how MCOs are key to managing obesity at the local level is important for healthcare providers. It can help MCOs and individual healthcare providers develop and coordinate strategies to educate stakeholders and better manage overall care.

Improving transitions of care for patients with thromboembolic disease.

Patients with or at risk for thromboembolic disease have many transitional interactions within the healthcare system. Transitions of care--when patients move between or within sites of care, or transition from inpatient to outpatient status--create repeated and diverse opportunities for medication errors, rehospitalization, and other adverse events that may increase costs. Although effective antithrombotic therapies are available, these therapies are complex, underprescribed, and frequently suboptimally managed, a situation further exacerbated by poor patient adherence to therapy. Physician and patient education may help address knowledge gaps related to antithrombotic therapy to help ensure that patients receive appropriate therapy and adhere to the therapeutic regimen. Due to the complexities of antithrombotic therapy it is not surprising that when these patients experience transitions of care, the potential for errors and suboptimal outcomes becomes compounded. Efforts are under way to improve the process of transitional care, including the development of protocols for medication reconciliation, improved communication between clinicians at hand-off, the use of electronic medical records, and the introduction of a collaborative approach among different types of healthcare providers, including pharmacists, nurses, and care managers, so that transitional care is provided smoothly and safely.

Effective and efficient diagnosis of parkinsonism: the role of dopamine transporter SPECT imaging with ioflupane I-123 injection (DaTscan™).

Parkinson's disease (PD), the second-most common neurodegenerative disease, is characterized by motor and nonmotor symptoms. PD is often misdiagnosed; inappropriate treatment due to misdiagnosis has undesired consequences, as does delayed diagnosis. Unfortunately, most people with PD receive a diagnosis only after motor symptoms have emerged, by which time 40% to 60% of dopamine neurons have already been lost. Advances in imaging techniques have provided clinicians with increasingly sophisticated tools. In 2011, the US Food and Drug Administration approved ioflupane I-123 injection (DaTscanTM) for striatal dopamine transporter visualization using single-photon emission computed tomography (SPECT) imaging, which provides an effective tool for assessing striatal dopaminergic deficiency. Among patients with suspected parkinsonian syndromes, of which PD is one, the diagnostic sensitivity and specificity of DaTscan SPECT imaging are high. In clinical studies that were part of the DaTscan new drug application, no serious drug-related adverse events reported by the 1236 participants were attributed to DaTscan. The introduction of DaTscan imaging and its utility necessitate the development of clinical recommendations for appropriate use; thus, a multidisciplinary panel of experts was convened to develop clinical criteria and algorithms to help guide clinicians and managed care organizations in the application of DaTscan SPECT imaging. Based on the consensus of this expert panel, appropriate use of DaTscan SPECT imaging includes cases where: (1) PD diagnosis is uncertain; (2) tremor of uncertain etiology is present; and (3) nonmotor and/ or supportive symptoms and features associated with PD are present but the classical motor syndrome is absent or atypical.

The importance of treatment adherence in HIV.

Treatment adherence is generally regarded as an important factor in achieving optimal outcomes across many disease states; in the treatment of HIV, poor adherence to treatment has the potential to impact outcomes on multiple levels. Poor adherence to antiretroviral therapy (ART) is associated with less effective viral suppression, which risks the immediate health of the patient, but also risks creating permanent treatment resistance to that particular agent or group of agents within a given combination therapy regimen. This may have downstream effects on treatment costs as well as therapeutic options. The causes of poor adherence to ART are extremely diverse, and include complexity of therapeutic regimens (eg, pill burden and dosing frequency), treatment side effects, poor health literacy, poor patient-physician relationship, and limited access to ART as a result of formulary restrictions or copayment costs. Treatment approaches, such as the use of fixed-dose combinations of ART agents to reduce dosing complexity, as well as educational interventions, such as medication therapy management initiatives, have been shown to improve adherence to therapy in HIV. It is important that all members of the healthcare team address potential barriers to adherence in order to achieve viral suppression and optimize outcomes in patients with HIV.

Asthma management guidelines: updates, advances, and new options.

BACKGROUND: Asthma still poses a substantial and unacceptable health and economic burden. The National Asthma Education and Prevention Program (NAEPP) guidelines for the management of asthma continue to evolve based on emerging clinical data, improving the understanding of asthma and approaches to its management. OBJECTIVE: To examine the clinical implications of current NAEPP guidelines for the diagnosis and treatment of asthma and the potential impact of the proposed 2007 guidelines update on asthma management. To examine the role of managed care organizations in fostering evidence-based asthma management. SUMMARY: Current NAEPP guidelines recognize symptom control as the chief therapeutic target in the management of asthma. The proposed update to NAEPP guidelines places greater emphasis on symptom control by expanding its definition to not only include measures of impairment but also the risk for deteriorating pulmonary function, asthma exacerbations, and controller medication side effects. Although inhaled corticosteroids remain central to achieving long-term asthma control in both current and proposed guidelines, the latter offers greater treatment flexibility and recognizes combination therapy as a preferred choice for achieving control in many patients with moderate persistent asthma. Managed care organizations, primarily using disease management programs, provide impetus for the widespread adoption of evidence-based asthma treatment guidelines. CONCLUSION: Widespread adoption of evidence-based asthma management programs offers the opportunity for achieving and maintaining asthma control.
