Laboratory System Improvement Program (L-SIP)

Home Assessment Improvement Resources



Welcome to the City of Milwaukee Health Department Laboratory’s website dedicated to our Laboratory System Improvement Program (L-SIP) and recent assessment held on May 10, 2018.

The 2018 assessment was the second conducted in Milwaukee. The City of Milwaukee became the first municipality to adapt and apply L-SIP at the local level with its initial assessment conducted in November 2010. Milwaukee’s L-SIP is part of a larger national effort, developed by the Association of Public Health Laboratories (APHL) and the Centers for Disease Control and Prevention (CDC), designed to strengthen state and local laboratory systems across the nation.

This site is designed to provide information and ongoing updates about our L-SIP and serve as an important tool in support of our collaborative efforts to strengthen the local public health laboratory system in Milwaukee. An Assessment Report will be posted here soon, along with next steps as we move into the improvement phase of the process.

Best Regards,

Sanjib Bhattacharyya, PhD

Laboratory Director



What is L-SIP?

L-SIP is a program of the Association of Public Health Laboratories (APHL), an organization that represents the interests of public health laboratories nationally and internationally. More information is available on this two-page overview of the L-SIP.

The purpose of the Laboratory System Improvement Program (L-SIP) is to improve the quality of public health laboratory practice and performance. The first step is to assess the strengths and weaknesses of the laboratory system as a basis for quality improvement efforts. Milwaukee’s most recent assessment took place on Thursday, May 10, 2018.


What is the Laboratory System?

The Local Public Health Laboratory (LPHL) System consists of all the organizations that participate in or otherwise support public health laboratory testing and includes those who initiate testing and those who ultimately use the test results. In Milwaukee this includes organizations in the city and county and extends into southeast Wisconsin. The LPHL System includes all public, private and voluntary entities that contribute to public health laboratory activities. LPHLSystem members and stakeholders operate in an interconnected and interdependent way to facilitate the exchange of information, optimize laboratory services and control and prevent disease and public health threats. See this description of the LPHL System for more details.


Why Participate in L-SIP?

L-SIP produces the following benefits for state and local public health laboratories:

  • Provides a benchmark for public health laboratory system practice improvements, by setting a “gold standard” to which public health systems can aspire.
  • Improves communication and collaboration by bringing partners (e.g., public health, environmental and other laboratories, first responders and key constituencies) together.
  • Educates stakeholders about the public health laboratory system and the interconnected activities that lead to collaborative system solutions.
  • Strengthens the diverse network of partners throughout the federal, state and local systems, leading to cohesive partnerships and better coordination of activities and resources.


What other Labs Participate?

A map of state and local laboratories that have completed L-SIP assessments depicts a total of 35 states and 5 local labs. Six agencies, including the City of Milwaukee Health Department Laboratory, have also gone on to complete subsequent assessments, or reassessments.
