Diabetes, a serious and costly condition, is characterized by illness and death from long-term microvascular and macrovascular complications (1). Additionally, numerous and well-known comorbidities can accompany diabetes, including cardiovascular disease, retinopathy, amputations, and nephropathy (1). Often these complications and comorbidities interfere with a person’s ability to self-manage their diabetes (2). The Centers for Disease Control and Prevention (CDC) projects that as many as 1 in 3 adults could have diabetes by 2050 (3). In 2012, the United States spent an estimated $245 billion on diabetes care, including $176 billion in direct medical costs and $69 billion in indirect costs from lost workdays, restricted activity, disability, and early death (4). Many costly complications among people with diabetes can be prevented or delayed with appropriate preventive care and self-management (5).

The Centers for Disease Control and Prevention (CDC) developed a cooperative agreement with health departments in all 50 states and the District of Columbia to strengthen chronic disease prevention and management efforts through the implementation of evidence-based strategies, such as CDC's National Diabetes Prevention Program. The National Diabetes Prevention Program supports organizations to deliver the year-long lifestyle change program that has been proven to prevent or delay the onset of type 2 diabetes among those at high risk. This article describes activities, barriers, and facilitators reported by funded states during the first 3 years (2013-2015) of a 5-year funding cycle.

CONTEXT: A recent systematic review found that use of an immunization information system (IIS) is an effective intervention to increase vaccination rates. The purpose of this review was to evaluate costs and benefits associated with implementing, operating, and participating with an IIS. The speed of technology change has had an effect on costs and benefits of IIS and is considered in this review. EVIDENCE ACQUISITION: An economic evaluation for IIS was conducted using methods developed for Community Guide systematic reviews. The literature search covered the period from January 1994 to March 2012 and identified 12 published articles and 2 government reports. EVIDENCE SYNTHESIS: Most studies involving cost data evaluated (1) system costs of building an IIS and (2) cost of exchanging immunization data; most economic benefits focused on administrative efficiency. CONCLUSIONS: A major challenge to evaluating a technology-based intervention is the evolution that comes with technology improvements and advancements. Although the cost and benefit data may be less applicable today due to changes in system technology, data exchange methods, availability of vendor support, system functionalities, and scope of IIS, it is likely that more up-to-date estimates and comprehensive estimates of benefits would support the findings of cost savings in this review. More research is needed to update and address limitations in the available evidence and to enable assessment of economic costs and benefits of present-day IIS.

CONTEXT: Immunizations are the most effective way to reduce incidence of vaccine-preventable diseases. Immunization information systems (IISs) are confidential, population-based, computerized databases that record all vaccination doses administered by participating providers to people residing within a given geopolitical area. They facilitate consolidation of vaccination histories for use by health care providers in determining appropriate client vaccinations. Immunization information systems also provide aggregate data on immunizations for use in monitoring coverage and program operations and to guide public health action. EVIDENCE ACQUISITION: Methods for conducting systematic reviews for the Guide to Community Preventive Services were used to assess the effectiveness of IISs. Reviewed evidence examined changes in vaccination rates in client populations or described expanded IIS capabilities related to improving vaccinations. The literature search identified 108 published articles and 132 conference abstracts describing or evaluating the use of IISs in different assessment categories. EVIDENCE SYNTHESIS: Studies described or evaluated IIS capabilities to (1) create or support effective interventions to increase vaccination rates, such as client reminder and recall, provider assessment and feedback, and provider reminders; (2) determine client vaccination status to inform decisions by clinicians, health care systems, and schools; (3) guide public health responses to outbreaks of vaccine-preventable disease; (4) inform assessments of vaccination coverage, missed vaccination opportunities, invalid dose administration, and disparities; and (5) facilitate vaccine management and accountability. CONCLUSIONS: Findings from 240 articles and abstracts demonstrate IIS capabilities and actions in increasing vaccination rates with the goal of reducing vaccine-preventable disease.
