Part 4: Improvement Strategies: Colorectal Cancer Screening
The actual improvement process is composed of three steps that respond to the following questions:
It is important to understand that improvement requires change, but not all change results in improvement. Considering all of the possible changes that can be made to health care systems, considerable effort has been dedicated to creating various quality improvement strategies providing a framework that organizes possible changes into logical categories. Frameworks for change in health care quality improvement are known as quality models and have been tested to guide change. In fact, considering that there are limited resources to dedicate to improvement, most organizations adopt one or more quality models to guide their improvement efforts. There is not a right or wrong approach, and there are many areas of overlap in quality models. Experienced quality improvement teams often use multiple strategies to overcome challenges as they progress. Two approaches often used by teams that are working to improve performance in Colorectal Cancer Screening are the Care Model approach and the Critical Pathway approach.
The Case Study: The Improvement Journey
Changes within these domains can effectively leverage transformation of a current reactive care system to one that better supports care for chronic disease conditions, such as colorectal cancer screening. Changes within these domains can effectively leverage transformation of a current reactive care system to one that better supports proactive care. If an organization does not have general experience with the Care Model, reading information on the Care Model
before proceeding is recommended. The Care Model recognizes that preventive care, such as Colorectal Cancer Screening for patients requires more proactive systems than the health care system often provides. The Care Model is implemented to improve care by working in six domains, defined below, that transform the way care is delivered:
Community-To improve the health of the population, a health care organization reaches out to form powerful alliances and partnerships with State programs, local agencies, schools, faith organizations, businesses, and clubs.
Organization of Health Care-A health care system can create an environment in which organized efforts to improve preventive care of patients takes hold and flourishes.
Self Management-Effective self management is very different from telling patients what to do. Patients have a central role in determining their care and one that fosters a sense of responsibility for their own health.
Delivery System Design-Delivery of patient care requires that an organization not only determines what care is needed, but clarify its roles and tasks to ensure the patient receives the care. An organization needs to ensure that all of the clinicians, who take care of a patient, have centralized, up-to-date information about the patient's status, and make follow-up a part of their standard procedures.
Decision Support-Treatment decisions need to be based on explicit, proven guidelines supported by at least one defining study. A health care organization integrates explicit, proven guidelines into the day-to-day practice of primary care providers in an accessible and easy-to-use manner.
Clinical Information System-A registry, that is, an information system that can track individual patients and populations of patients, is a necessity when managing chronic illness or preventive care.

Critical Pathway Approach: As with all critical pathways, good performance relies on many different systems and processes working together efficiently. An organization is encouraged to map its own critical pathway for Colorectal Cancer Screening or refer to the schematic in Figure 4.2. Often when a QI team maps its pathways, it readily can see how complex each step is. It is common for different team members to do the same step differently. Workflow inefficiencies become clear when an organization visualizes how each step is completed and the interdependencies among the steps. Some teams are overwhelmed by the possibilities of changes that can be made in their systems; others focus only on a specific group of factors.
One way to organize the factors that have an impact on the systems is to consider that some are controlled by the patient, others are primarily controlled by the care team, and still others are inherent in the system of care delivery. All three sets of changes must be considered to improve systems of care. In general, these categories can be defined as follows:
A team should use the steps along the critical pathway to target improvements. For this measure, Colorectal Cancer Screening, influences and performance begin by ensuring that the appropriate screening is completed (not simply ordered), as indicated by the fifth step in the critical pathway, colorectal cancer screening completed.
An organization should ensure that patients are appropriately educated regarding the importance of regular colorectal cancer screening based on their level of risk. Providing education to patients also affords an organization the opportunity to assess patient barriers to screening, such as, lack of insurance or cost. Successful organizations have often aligned resources in the community for screening at a reduced cost for patients creating a true partnership in patient care.
An organization can think through each part of the critical pathway in turn, teasing out what happens and what could be improved. In Table 4.2, changes that have worked for other QI teams are matched with the part of the system on which they have the most impact. These ideas are not meant to be inclusive, but to start a dialogue of what may improve each part of the critical pathway in an organization, and thus improve it overall.
Table 4.2: Sample Changes That Work That Are Linked to the Critical Pathway for Colorectal Cancer
Earlier in this module, examples are provided of changes that have led to improved organizational systems of care and better patient health outcomes (Critical Pathway and Care Model). Because every change is not necessarily an improvement, changes must be tested and studied to determine whether the change improves the quality of care. This concept is addressed in detail in the Testing for Improvement module.
It is important that these changes be tested in the context of an organization's staff, current processes, and patients. The goal is that the change results in lasting improvements within an organization.
Organizations commonly use tools to manage change as they work to improve their systems. For a comprehensive discussion of change management, refer to the Testing for Improvement and Redesigning a System of Care to Promote QI modules. Here are a couple of tools that are worth mentioning in the context of this measure:
Model for Improvement
The Model for Improvement (26) identifies aim, measure, and change strategies by asking three questions:

These questions are followed by the use of learning cycles to plan and test changes in systems and processes. These are referred to as PDSA (Plan-Do-Study-Act) cycles. The PDSA Cycle is a test-and-learning method for discovering effective and efficient ways to change a current process. In Figure 4.3: The PDSA Cycle, the graphic provides a visual of the PDSA process:

An organization focusing its improvement efforts on Colorectal Cancer Screening for its patients benefits from implementing PDSAs to test change processes that have an impact on obtaining the appropriate screening for colorectal cancer. Those organizational processes tested may focus on outreach, operational procedures, or patient education interventions ensuring that patients have timely access to care. A few examples of such processes relating to Colorectal Cancer Screening are listed below:
As an organization plans to test a change, it should specify who, what, where, and when so that all staff know their roles clearly. Careful planning results in successful tests of change. Documentation of what happened – the S or study part of the PDSA – is also important. This can help a team to understand the impact of changes to a process as unanticipated consequences may occur.

Tips for Testing Changes
Process Mapping
Process mapping is another valuable tool that an organization focused on improvement often uses. A process map provides a visual diagram of a sequence of events that result in a particular outcome. Many organizations use this tool to evaluate a current process and again when restructuring a process.
The purpose of process mapping is to use diagramming to understand the current process; i.e., how a process currently works within the organization. By looking at the steps, their sequence, who performs each step, and how efficiently the process works, a team can often visualize opportunities for improvement.
Process mapping can be used before or in conjunction with a PDSA cycle. Often, mapping out the current process uncovers unwanted variation. In other words, different staff may perform the process differently, or the process is changed on certain days or by specific providers. By looking at the process map, a team may be able to identify gaps and variation in the process that have an impact on colorectal cancer screening for patients.
Both of these improvement strategies are illustrated in Example 4.1:
Example 4.1: Illustrations of Improvement Strategies
Successful referral to a patient navigator
At a small clinic in the northeast, the organization's improvement team found that 25 percent of its patients aged 50 to 80 years had an appropriate screening for colorectal cancer. Further investigation revealed that the main reason for a missed appointment for screening was fear. The improvement team decided to look at the process and decided to use the patient navigator at the hospital to contact patients for screening. The referral process to the patient navigator was:
The team felt that Steps 2 and 3 were potential problems in the process and analyzed how they could be improved. Phone calls were made to five patients who had been referred to the patient navigator to assess their experiences. Two had attended their appointments but had difficulty finding the navigator's office; two had not attended because they felt that it would not be worthwhile, and one developed a schedule conflict after the appointment had been made. There was no notation that the three patients had no-showed their appointments in the patients' charts.
The QI team considered various strategies, such as, providing clearer instructions for patients, providing education on site, and improving the feedback loop between the navigator and the provider. The team investigated the option of contracting with the patient navigator for a half day per week to work on site and found that it could be reimbursed for her services. This arrangement was put in place as a three-month trial and referral completion rates were monitored monthly. Although attendance was not perfect, it was significantly better than when patients were referred off site. The team also emphasized that notes from the visit, or that the patient no-showed, was critical information that must be documented in the patient's chart.
The team strategy was successful. By having the patient navigator on site, access to the service was simplified and was perceived by patients to be more integrated with their provider's care.
Measures and data are necessary to answer this question. Data is needed to assess and understand the impact of changes designed to meet an organization's specified aim. Measurement is essential in order to be convinced that changes are leading to improvement. Organizations that have experienced successful improvement efforts found that data, when shared with staff and patients outside the core improvement team, led to the spread of improvement strategies, in turn generating interest and excitement in the overall quality improvement process.
Measures are collected prior to beginning the improvement process and continue on a regularly scheduled basis throughout the improvement program. Once an organization reaches its specified goal, frequency of data collection may be reduced. Additional information regarding frequency of data collection, tracking, and analyzing data can be found in the Managing Data for Performance Improvement module.
