CAHPS Surveys: Essential Tools for Patient-Centered Care Improvement

Introduction

In the evolving landscape of healthcare, the focus has increasingly shifted towards patient-centered care. This approach prioritizes the patient’s needs, preferences, and values, ensuring that healthcare delivery is not only clinically effective but also respectful and responsive to individual patients. Measuring and improving patient experience is paramount to achieving truly patient-centered care. This is where the Consumer Assessment of Healthcare Providers and Systems (CAHPS) surveys come into play, offering standardized and validated tools to assess and enhance the patient experience across various healthcare settings. Originally designed and championed by the Agency for Healthcare Research and Quality (AHRQ), CAHPS surveys have become the gold standard for understanding patient perspectives on healthcare quality. They provide actionable data that healthcare organizations can use to drive meaningful improvements in care delivery and ultimately, advance patient-centeredness.

The Development and Rigor of CAHPS Surveys

The strength of CAHPS surveys lies in their rigorous development process and their focus on measuring aspects of care that are directly observable by patients. Unlike measures that focus solely on clinical outcomes or provider-centric metrics, CAHPS surveys delve into the patient’s actual experiences during care delivery. The development of the CAHPS Cancer Care Survey, for example, exemplifies this meticulous approach.

The process began with extensive formative research, including numerous focus groups with cancer patients and their families. These sessions aimed to identify the aspects of cancer care that were most important to patients and that reflected high-quality, patient-centered care. Input was also gathered from expert panels of oncologists and quality improvement specialists, as well as stakeholders from oncology associations and cancer centers. This multi-faceted approach ensured that the survey content was relevant, comprehensive, and aligned with the priorities of both patients and healthcare professionals.

Cognitive testing was a crucial step in refining the survey questions. Patients were asked to review draft questions to assess their clarity, comprehensibility, and relevance to their experiences. This iterative process of testing and revision ensured that the final survey instrument was easily understood by patients from diverse backgrounds and accurately captured their intended experiences. Following cognitive testing, field tests were conducted in real-world cancer care settings, including cancer centers and community oncology practices. These field tests evaluated the survey’s psychometric properties, ensuring its reliability and validity in measuring patient experience. The result of this rigorous development is a survey that is not only patient-centered in its focus but also scientifically robust and dependable for quality measurement.

Core Components and Measures within CAHPS Cancer Care Survey

The CAHPS Cancer Care Survey is a comprehensive instrument designed to assess multiple dimensions of patient experience. It comprises 56 questions that coalesce into six core composite measures, each targeting a critical aspect of patient-centered care:

Getting Timely Care: This measure assesses patients’ ability to access care when they need it, a fundamental element of responsive healthcare.
Supporting Patient Self-Management: This composite explores the extent to which providers equip patients with the knowledge and tools necessary to manage their health effectively, promoting patient empowerment and active participation in their care.
Available to Provide Care and Information: This measure focuses on the accessibility and responsiveness of care providers when patients need assistance or information, highlighting the importance of readily available support.
Provider Communication: Effective communication is at the heart of patient-centered care. This composite evaluates how well providers communicate with patients, ensuring clear, understandable, and respectful information exchange.
Care Coordination: For patients with complex health needs like cancer, coordinated care is essential. This measure assesses the effectiveness of care coordination among different providers and settings, ensuring seamless and integrated care experiences.
Courteous Office Staff: The interactions with office staff significantly shape the overall patient experience. This measure assesses the courtesy and helpfulness of office staff, recognizing their crucial role in creating a positive care environment.

Beyond these core composites, the survey also includes single-item measures that address important aspects such as family participation in care and the availability of interpreter services, recognizing the diverse needs of patient populations. Furthermore, two global rating questions capture patients’ overall impressions of their cancer care and their treatment team, providing a summary assessment of their overall experience.

To offer even more granular insights, the CAHPS Cancer Care Survey incorporates supplemental composite measures. These include:

Shared Decision-Making: This measure delves into the extent to which patients feel involved in making decisions about their treatment, a cornerstone of patient autonomy and respect for preferences.
Keeping Patients Informed: Going beyond basic communication, this composite assesses how well providers keep patients informed about their condition, treatment, and progress, ensuring transparency and knowledge sharing.
Access to Care: This supplemental measure further explores different facets of access to care, providing a more detailed understanding of potential barriers and facilitators to timely and appropriate care.

Methodological Recommendations and Data Collection

To ensure the reliable and valid collection of patient experience data, CAHPS surveys provide clear guidelines for data collection methodologies. For the Cancer Care Survey, recommended methods include mail-only, mail-telephone mixed-mode, and Web-mail mixed-mode approaches. These options offer flexibility for different healthcare settings and patient populations, allowing organizations to choose the method that best suits their context and resources.

The mail-only approach involves sending survey questionnaires to patients via postal mail. The mail-telephone mixed-mode method combines mail surveys with telephone follow-up for non-responders, potentially increasing response rates. The Web-mail mixed-mode approach leverages online surveys, offering patients the convenience of responding electronically, while also incorporating a mail component to reach those who may not have internet access or prefer paper-based surveys.

These recommended methodologies are designed to maximize patient participation and ensure representative data collection. By adhering to these guidelines, healthcare organizations can collect high-quality data that accurately reflects the experiences of their patient population.

Psychometric Properties and Validation

The CAHPS Cancer Care Survey has undergone rigorous psychometric testing to establish its reliability and validity. Psychometric properties refer to the measurement characteristics of a survey, indicating how well it measures what it is intended to measure and how consistently it does so.

Key psychometric measures evaluated for the CAHPS Cancer Care Survey include:

Interunit Reliability (IUR): This measure assesses the survey’s ability to differentiate between healthcare units (e.g., cancer centers) in terms of patient experience. An IUR of 0.70 or greater indicates good reliability at the unit level.
Internal-Consistency Reliability (Cronbach’s α): This measure assesses the extent to which items within a composite measure are related to each other. A Cronbach’s α of 0.70 or greater is generally considered acceptable, indicating that the items are measuring a similar underlying construct.
Criterion (Concurrent) Validity: This assesses how well the survey measures correlate with other measures of related concepts. For CAHPS surveys, correlations with global ratings of care are examined, with correlations greater than 0.30 indicating acceptable validity.
Scaling Success: This refers to the extent to which items within a composite measure correlate more strongly with their intended composite than with other composites. A scaling success of 100% indicates strong construct validity.
Ceiling and Floor Effects: These assess the distribution of scores. High ceiling effects (a large proportion of respondents giving the highest possible score) or floor effects (a large proportion giving the lowest possible score) can limit the survey’s ability to detect differences and improvements. For CAHPS surveys, ceiling effects below 75% are generally considered acceptable.
