Efficacy vs. Effectiveness
• Efficacy: How well an intervention works in optimal settings– Well-trained and paid research staff– Controlled Setting– Carefully recruited study subjects– Carefully constructed and executed
research protocol
![Page 3: From Efficacy to Effectiveness: the Safe in the City Model](https://reader036.vdocuments.us/reader036/viewer/2022062519/56815128550346895dbf45be/html5/thumbnails/3.jpg)

Efficacy vs. Effectiveness
• Effectiveness: How well an intervention works in the real world– Staff not specifically trained for intervention; and
need to meet competing demands– Targets all patients/clients, not selected subjects– Adaptation of intervention protocol often
necessary to make it practical for the setting (threat to fidelity)
![Page 4: From Efficacy to Effectiveness: the Safe in the City Model](https://reader036.vdocuments.us/reader036/viewer/2022062519/56815128550346895dbf45be/html5/thumbnails/4.jpg)

Effectiveness Research
• Implicitly takes into account the acceptability, feasibility, implementation, and impact of an intervention in the settings for which the intervention was designed
![Page 5: From Efficacy to Effectiveness: the Safe in the City Model](https://reader036.vdocuments.us/reader036/viewer/2022062519/56815128550346895dbf45be/html5/thumbnails/5.jpg)

Effectiveness Research3 Main Components
• Participatory research model
• Efficacy/Effectiveness evaluation
• Scale-up process and evaluation
![Page 6: From Efficacy to Effectiveness: the Safe in the City Model](https://reader036.vdocuments.us/reader036/viewer/2022062519/56815128550346895dbf45be/html5/thumbnails/6.jpg)
6
Participatory Research Model
• Involves all stake holders that determine the ultimate success of the intervention:– Academics / intervention developers– Target population representatives– Representatives from the organizations
responsible for implementation
![Page 7: From Efficacy to Effectiveness: the Safe in the City Model](https://reader036.vdocuments.us/reader036/viewer/2022062519/56815128550346895dbf45be/html5/thumbnails/7.jpg)

Efficacy/Effectiveness Evaluation
• Evaluation of efficacy/effectiveness should take place in an environment that closely mimics the environment for which the intervention is ultimately intended
![Page 8: From Efficacy to Effectiveness: the Safe in the City Model](https://reader036.vdocuments.us/reader036/viewer/2022062519/56815128550346895dbf45be/html5/thumbnails/8.jpg)

Scale – Up Process and evaluation
• Marketing strategies and implementation
• Evaluation of intervention up-take by target audience
• Short to long term assessment of implementation and sustainability

Study Rationale
340,000,000 incident STDs worldwide annually
STD clinics provide access to men and women likely to be infected and to acquire new infections over time
Yet behavioral interventions with counseling or multiple sessions are difficult to implement in busy medical settings
Recent interest in simple, easy to use, and low cost interventions for waiting rooms
![Page 14: From Efficacy to Effectiveness: the Safe in the City Model](https://reader036.vdocuments.us/reader036/viewer/2022062519/56815128550346895dbf45be/html5/thumbnails/14.jpg)
14
Rationale continued
Previous research suggests benefits of video-based approaches, but subject to limitations:
Controlled research settings Tailored videos Single site Inclusion of group counseling
Effectiveness of stand-alone video in ‘real-world’ setting is unknown
![Page 15: From Efficacy to Effectiveness: the Safe in the City Model](https://reader036.vdocuments.us/reader036/viewer/2022062519/56815128550346895dbf45be/html5/thumbnails/15.jpg)

Safe in the City Project Overview
5-year CDC-funded multi-site study
Develop a brief video-based STD clinic waiting room intervention to reduce (or eliminate) STI and risky sexual behavior
Evaluate effectiveness in 3 publicly funded STD clinics in Denver, San Francisco, and Long Beach, CA.
![Page 16: From Efficacy to Effectiveness: the Safe in the City Model](https://reader036.vdocuments.us/reader036/viewer/2022062519/56815128550346895dbf45be/html5/thumbnails/16.jpg)
16
Intervention Development Considerations
Waiting rooms in medical settings provide an underused opportunity to reach patients who are thinking about their health.
Yet to be feasible and sustainable, interventions must:
Be easy and inexpensive to administer
Result in minimal interruption of patient flow
Require few clinic resources, especially staff time
Be acceptable to diverse clients
![Page 17: From Efficacy to Effectiveness: the Safe in the City Model](https://reader036.vdocuments.us/reader036/viewer/2022062519/56815128550346895dbf45be/html5/thumbnails/17.jpg)
17
Formative Process
Identification of intervention medium, theoretical framework, and key messages by research team
Collaboration with award-winning film maker to integrate framework in an appealing product
Multi-step participatory process involving target audience, clinic staff, and community advisors
Intervention research study in 3 STD clinics
![Page 18: From Efficacy to Effectiveness: the Safe in the City Model](https://reader036.vdocuments.us/reader036/viewer/2022062519/56815128550346895dbf45be/html5/thumbnails/18.jpg)

Intervention Development: Integrated Theoretical
Framework
Core constructs grouped into interconnected elements
→ HIV/STD risk, knowledge, perception→ Positive attitudes toward condom use
→ Self-efficacy/skills for condom negotiation, acquisition, use→ Modeling of appropriate behaviors
Theory of Planned Behavior
Social Cognitive Theory
Information Motivation
Behavior Model

Assessing Intervention Effectiveness in an STD Clinic Population:

27
Examples of Challenges in Study Design
• Examining “real-world” effectiveness prohibits active patient enrollment *still need to deliver intervention, include entire clinic population
• Large sample size required, given effectiveness of brief intervention likely modest
• Biologic markers (STI) preferred effectiveness measure to self-reported behavior
• Unable to randomize in waiting room setting, but need balance between study conditions
![Page 28: From Efficacy to Effectiveness: the Safe in the City Model](https://reader036.vdocuments.us/reader036/viewer/2022062519/56815128550346895dbf45be/html5/thumbnails/28.jpg)

Maximizing Intervention Delivery and Exposure
Identify environmental characteristics of waiting rooms
Observe waiting room flow
Determine appropriate playback frequency
Identify factors to increase viewership (goal: 80%)
Assess and adjust to clinic staff acceptance of video

Approach to Statistical Analysis
Outcome: Incident laboratory-confirmed infection – gonorrhea, chlamydia, trichomoniasis, syphilis, and HIV
Analysis: Survival analyses estimating time to infection– Kaplan-Meier analyses comparing survival at specific
points in time by condition*
– Cox proportional hazards regression comparing hazard ratios by condition*

44
Meeting Challenges in Study Design
• Evaluation of intervention effectiveness in “real-world” setting with “passive enrollment” of patient population
• Efficient examination of laboratory-confirmed STI using existing medical / surveillance records
• Inclusion of entire patient population, ensuring generalizability
• Non-randomized design with systematic allocation balanced all measured characteristics
![Page 45: From Efficacy to Effectiveness: the Safe in the City Model](https://reader036.vdocuments.us/reader036/viewer/2022062519/56815128550346895dbf45be/html5/thumbnails/45.jpg)
45
Factors Critical to Success of Evaluation
• Ability to examine study population in advance: – Patient flow (e.g., number of patients, waiting room
time)– Reaction of patient / staff to video– STI prevalence and incidence of population known
• Access to electronic medical records and surveillance registries to identify incident STI
• Waiver of informed consent from IRB critical
![Page 46: From Efficacy to Effectiveness: the Safe in the City Model](https://reader036.vdocuments.us/reader036/viewer/2022062519/56815128550346895dbf45be/html5/thumbnails/46.jpg)
46
Conclusions “Safe in the City” associated with reduction in incident STI *** important -- estimate = effectiveness, not efficacy.
This reduction can have significant public health benefit, but requires sufficient availability of intervention and wide adoption by clinics.
Relatively* easy-to-implement, low cost interventions can reach large numbers of high-risk populations with minimal effort.
Type of design used to examine effectiveness of “Safe in City” promising for studies of STD prevention interventions.
