Evaluation of the Preventive Health and Health Services Block Grant

CDC’s Center for State, Tribal, Local, and Territorial Support is conducting an ongoing evaluation of the Public Health and Health Services (PHHS) Block Grant. The evaluation assesses the grant’s value (i.e., its benefits and contributions) and describes and measures select outputs and outcomes, with the aim of strengthening performance and accountability. The evaluation assesses the grant as a whole—not individual grantee activities or outcomes. The evaluation seeks to answer two overarching questions:

  1. How does the PHHS Block Grant support grantees in addressing their jurisdictions’ prioritized public health needs related to Healthy People 2020 objectives?
  2. How does the PHHS Block Grant contribute toward the achievement of organizational-, systems-, and health-related outcomes?

The evaluation consists of several key activities, including implementing a measurement framework to assess grantee achievements, analyzing grantee allocation of funding to Healthy People 2020 objectives, and exploring the relationship between PHHS Block Grant funding and health outcomes.

The Measurement Framework

A key component of the evaluation is the PHHS Block Grant Measurement FrameworkCdc-pdf[PDF – 581 KB]. The framework is an innovative measurement approach that allows for more standardized data collection and aggregation of the outputs, outcomes, and achievements of health departments using grant funds.

The framework consists of four key measures:

  1. Improvement in the capacity of information systems to collect data of public health importance
  2. Improvement in the efficiency or effectiveness of operations, programs, or services
  3. Emerging public health needs addressed
  4. Evidence-based public health interventions implemented

Data Collection

In October 2017, CSTLTS conducted the first data collection using this framework. Data were collected on the measures using a web-based questionnaire given to PHHS Block Grant coordinators. The data collection covered the grantees’ performance period of July 1, 2016–June 30, 2017. The response rate for the questionnaire was 93% (n=57/61).

Key Findings

The PHHS Block Grant is supporting vital public health activities in grantees’ jurisdictions. Grantees are collectively using their funds to improve their ability to collect essential data; improve the efficiency and effectiveness of operations, programs, and services; address emerging needs; and implement evidence-based interventions. Below are highlights of the findings.

The report presents the first aggregate measurement of grant outcomes for the PHHS Block Grant.

Public Health Infrastructure Improved

Information Systems Capacity Improved

The PHHS Block Grant is helping health departments improve the capacity of their public health information systems. The data collected by public health information systems are essential for identifying, prioritizing, and effectively addressing public health problems. These systems provide timely, actionable data for decision-making not only by the grantee, but also by the local and tribal health departments that use these systems.

74% of grantees (42 of 57) used Block Grant funds to develop, improve, and/or maintain one or more information systems.

164 health departments developed, improved, and/or maintained a total of 153 information systems (112 Local, 12 Tribal, and 30 Grantees).

Quality Improved

Grantees are using PHHS Block Grant funds to improve efficiency and effectiveness within their agencies and in other agencies within their jurisdiction. More than two-thirds of grantees implemented quality improvement projects that improved the efficiency and/or effectiveness of one or more operations, programs, and services. These quality improvement activities contribute to grantees’ ongoing efforts toward measurable improvements in services or processes that improve their communities’ health.

67% of grantees (38 of 57) used Block Grant funds for a quality improvement effort.

376 health departments improved the efficiency and/or effectiveness of at least one operation, program, or service (344 Local, 2 Tribal, and 30 Grantees).

Emerging Public Health Needs Addressed

Grantees are using PHHS Block Grant funds to address specific emerging public health needs in their jurisdictions, such as opioid/prescription drug abuse and other challenges. Protecting and improving public health often requires flexibility to tackle public health problems as they emerge within the varying contexts in states, tribes, and territories. The PHHS Block Grant funds are used as a resource for health departments to address their jurisdictions’ emerging public health needs.

68% of grantees (39 of 57) used Block Grant funds to address emerging public health needs.

111 emerging public health needs, spanning a variety of topic areas, were addressed by health departments.

Evidence-Based Public Health Practiced

The PHHS Block Grant is being used to implement public health interventions1 that are known to work. Implementing public health interventions based on the best available evidence is an important practice for maximizing public health outcomes. The majority of grantees used grant funds to implement public health interventions, most of which were evidence based. Most of the interventions that were new or innovative (i.e., had weak or no evidence) were assessed to see how well they work.

84% of grantees (47 of 56) used Block Grant funds to implement public health interventions.

568 of 628 interventions (90%) reported were evidence-based.

Most (70%) of the interventions that were not evidence-based were untested, innovative, and/or new.

Grantees collected data on almost 3 our of 4 interventions that were not evidence-based to see if they worked, thereby generating practice-based evidence.


  1. For the purposes of this evaluation, public health interventions are defined as any type of planned activity, such as a program, service, or policy, designed to prevent disease or injury or promote health in a group of people.
