About the Data
Description of the data source, numerator, denominator, survey questions, and other relevant details about the national estimate.
Number of public health laboratory systems that perform at a high level of quality in evaluating effectiveness, accessibility, and quality of personal and population-based health services
Number of public health laboratory systems that respond to the Public Health Laboratory Systems Survey
- Strongly agree
- Agree
- Disagree
- Strongly disagree
From the 2012 Public Health Laboratory Systems Survey:
[NUMERATOR:]
Measurement: The laboratory system participates in the evaluation of the effectiveness, accessibility, and quality of laboratory services needed in the community.
Optimal condition: Members of the State Public Health Laboratory System have a mechanism in place to measure and evaluate services and operations in the system to assure that the needs of the community continue to be met, the quality of services provided are high, and changes are made when quality and access objectives are not met.
Question: How much do you agree or disagree with the following statement: “The partners and stakeholders within my state routinely collaborate to evaluate the effectiveness, accessibility, and quality of laboratory services within the system.”?
The Public Health Laboratory Systems Survey (PHLSS) includes one question on the evaluation of effectiveness, accessibility, and quality of personal and population-based health services. 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 evaluation of effectiveness, accessibility, and quality of personal and population-based health services.
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.
