Turning great ideas into healthier communities



PHI offers a full suite of evaluation services—from first design to analysis—to assess what’s working, identify needs for quality improvement, and demonstrate impact and success. PHI's experience includes  public procurement standards, sugary beverage consumption, marijuana and alcohol policy evaluation, multi-unit housing policies to support tobacco prevention and cessation, and physical activity promoting community design. Our experts design evaluation metrics and assess the efficacy of current or proposed public health programs and policy to provide clear findings and scalable recommendations. We emphasize the engagement of  community residents, partners, and other stakeholders in the collection and evaluation processes.

Here's How We're Making a Difference

Advancing 50+ Years of Research with PHI's Alcohol Research Group

Founded over fifty years ago, PHI's Alcohol Research Group (ARG) is a multidisciplinary research center whose focus is to conduct research on alcohol use patterns and associated problems and dissemination of research findings. Their research team is comprised of epidemiologists, psychologists, economists and researchers in other disciplines.

ARG researchers have publishedmore than 1000 peer-reviewed journal articles, including one study that found privatization of liquor sales in Washington state resulted in substantially higher prices to consumers on average. ARG's Alcohol Research Center was also redesignated as a PAHO/WHO Collaborating Center on Alcohol Epidemiology and Injury through September 2019. 

Advancing Innovative Opioid Prevention Partnerships to Save Lives

The opioid epidemic is having a devastating impact in communities across the nation, fueling a dramatic increase in premature deaths. In California, there were almost 2,000 opioid overdose deaths in 2016. In late 2015, the California Health Care Foundation (CHCF) launched a statewide network of 16 local coalitions in 23 counties focused on three priority strategies—safe opioid prescribing, use of medication-assisted addiction treatment (MAT), and access to naloxone to reverse drug overdoses. 

In 2017, PHI conducted an assessment of the California Health Care Foundation’s network of opioid safety coalitions to identify what strategies are working at the local level. PHI found that more than 90% of coalitions facilitated adoption of safer prescribing guidelines, more than 75% increased access to naloxone to reverse overdoses, and more than 50% expanded use of medication-assisted addiction treatment.

Evaluating Michigan's Produce for Pantries Program

The Michigan Produce for Pantries program encourages home and community gardeners to plant, grow and share produce with food pantries in their neighborhoods—providing over 5,000 food pantry clients with access to homegrown fresh fruits and veggies, and helping to connect them with SNAP-Ed resources and trainings from the Michigan Harvest of the Month program.

In their evaluation, PHI’s Survey Research Group found that food bank clients reportedly loved Produce for Pantries, especially the taste testing and interactions with the nutrition educators. Most felt confident they could prepare the fruits and vegetables they received from the emergency food distribution sites at home, and eighty-nine percent of clients felt very sure they could prepare the produce they took home in a way that their family would eat and enjoy.

Survey Research Group also evaluated the effects of the Produce for Pantries program on fruit and vegetable intake and assessed policy, systems, and environmental change strategies to implement at emergency food distribution sites.
