PHI-12.3 Increase the proportion of public health laboratory systems (including State, Tribal, and local) that perform at a high level of quality with respect to informing, educating, and empowering people about health issues

About the Data

Description of the data source, numerator, denominator, survey questions, and other relevant details about the national estimate.

Data Source: 
Public Health Laboratory Systems Survey
Changed Since the Healthy People 2020 Launch: 
Yes
Measure: 
percent
Baseline (Year): 
28 (2012)
Target: 
31
Target-Setting Method: 
10 percent improvement
Numerator: 

Number of public health laboratory systems that perform at a high level of quality in informing, educating, and empowering people about health issues

Denominator: 

Number of public health laboratory systems that respond to the Public Health Laboratory Systems Survey

Comparable Healthy People 2010 Objective: 
Not applicable
Questions Used to Obtain the National Baseline Data: 

    From the 2012 Public Health Laboratory Systems Survey:

    [NUMERATOR:]

    Measurement: The efficacy of outreach and communication is identified and targeted for both incoming and outgoing laboratory information for health and non-health partners in the community to improve health education initiatives with community and system partners.

    Optimal condition: Partners within your state are actively engaged in creating and distributing accurate and relevant information about laboratory issues to health and non-health partners, and soliciting feedback on a regular basis.

    Question: How much do you agree or disagree with the following statement: “The partners in my State Public Health Laboratory System provide information about laboratory-related health issues that are communicated to providers and the general public in a timely fashion.”?

    1. Strongly agree
    2. Agree
    3. Disagree
    4. Strongly disagree
Data Collection Frequency: 
Biennial
Methodology Notes: 

    The Public Health Laboratory Systems Survey (PHLSS) includes one question on the informing, educating, and empowering of people about health issues. This question solicits Likert scale responses, such as Strongly Agree, Agree, Disagree and Strongly Disagree. Responses of “Strongly Agree” are assigned a score of 2, “Agree” 1, and “Disagree/Strongly Disagree” 0. Scores are then averaged. If the average score is 1.5 or higher, then the laboratory system is deemed to be performing at a high level of quality in the informing, educating, and empowering of people about health issues.

    The PHLSS was distributed via an Internet survey to all state (and D.C.) public health laboratory directors. The PHLSS has 10 sections that correspond to the 10 Essential Public Health Services. Each section has one to three questions about the relevant Essential Service that solicit Likert scale responses. The Association of Public Health Laboratories (APHL) had previously developed a document called the “Key Elements/Capacities for Highly Functioning State Public Health Laboratory Systems” that was the guide in the creation of the PHLSS. The document identifies the capacities that should be in place in a State Public Health Laboratory System in order for that system to be functioning at a high level in support of the 10 Essential Public Health Services. A taskforce composed of APHL members and staff developed questions that asked for the respondent’s level of agreement as it pertained to statements of a State Public Health Laboratory System’s performance based on the “Key Elements” document.

Caveats and Limitations: 
2012 data were based on DC and 42 states excluding AK, DE, MD, ND, NJ, SC, UT, and WA.

Revision History

Any change to the objective text, baseline, target, target-setting method or data source since the Healthy People 2020 launch.

Description of Changes Since the Healthy People 2020 Launch: 
In 2013, objective PHI-12 became measurable. Ten new objectives (PHI-12.1 through 12.10) were created, each addressing one of the 10 Essential Public Health Services. Although the objective language includes State, Tribal, and local public health laboratories, the current measure includes only State laboratories.
