Quality Improvement/Patient Safety Issues Relevant to Rehabilitation

Quality improvement (QI) and patient safety (PS) are closely linked. PS, viewed as a component of quality, refers to preventing unnecessary harm to the patient. QI activities may improve outcomes such as reducing costs, enhancing efficiency, improving satisfaction, and preventing harm.

QI consists of systematic and continuous actions that lead to measurable improvement in health care services and the health status of a targeted patient group. Competence in QI is important for medical trainees, as the Accreditation Council of Graduate Medical Education (ACGME) now recognizes QI as a required component of graduate medical education. Involvement in QI can take many forms through improvements in educational programs, patient care and safety, and research.

There are many definitions of quality. Donabedian classical review on quality of medical care concludes that “quality of care is a remarkably difficult notion to define”; often based on value judgments as they relate to general goals or standards. 1 Donabedian suggests that, in general, quality has to do with the following measures:

Quality improvement, as defined by Centers for Medicare and Medicaid Services, is “the framework used to systematically improve care.” 2 Systematic behavior allows standardization of processes to reduce variation, identify best practices, and improve overall outcomes. The Institute for Healthcare Improvement (IHI) espouses the Model for Improvement as their framework for instituting change. 3 The model starts with a question rooted in understanding of a system and then creates a plan of change with importance placed on measuring effectiveness of the change.

Each of these definitions has its value and limitations. Processes are the functions over which healthcare providers have the most control. Certain processes, such as mortality discussion and patient satisfaction questionnaires, have been linked to improved outcomes. However, improving the process may not always improve the overall quality of care perceived by the patient. For example, the esthetic appeal of structures (e.g., hospital buildings) may have little to do with the quality of care provided. Although QI often strives to improve outcomes, multifactorial aspects of outcomes need to be considered. For instance, length of hospital stay as an outcome may be influenced by psychosocial factors, disease severity, and comorbidities which make it challenging when comparing length of stay among different patients with the same diagnosis.

A critical aspect of implementing any QI initiative is following a systematic approach, of which there are many formal frameworks that can be utilized. For example, two of the most common examples of QI models used in healthcare include the Plan-Do-Study-Act (PDSA) Cycle and Lean Six Sigma. 1,4

Relevance to Clinical Practice

Sources and Methods of Obtaining Information

Sampling/selection from these sources needs to be representative of the general population.

Sources

Measurement Standards

Collected data may be assessed against internal or external standards. Internal standards assess change from a baseline for a given program, for example, an increase in the average Functional Independence Measure TM (FIM) efficiency from one year to the next. Examples of external standards are guidelines, which may be normative (e.g., expert opinion), empirical (i.e., supported by clinical evidence), or comparative data from multicenter datasets.

Clinical Examples in Physical Medicine and Rehabilitation

Process

Assessment of implementation of established processes is often measured as adherence to guidelines. These guidelines may be established by expert panels (e.g., American College of Chest Physician Guidelines for VTE Prophylaxis) based on various levels of evidence. The National Guideline Clearinghouse, run by the Agency for Healthcare Research and Quality, contains searchable links to many commonly accepted guidelines. 5 Physical Medicine and Rehabilitation (PM&R) specific guidelines are also available online. 6 These include guidelines developed and/or endorsed by the American Academy of Physical Medicine and Rehabilitation (AAPM&R).

Outcomes

Outcomes are generally compared with criterion standards or by benchmarking them against similar institutions regionally or nationally. A classic example is the FIM, used by most inpatient rehabilitation programs throughout the United States to measure the level of a patient’s disability and how much assistance they need to carry out activities of daily living.

Outcome measures should be risk-adjusted for factors such as disease severity, comorbidities, and psychosocial status.

Structure

Structure is often dictated by external reviewers:

Clinicians performing quality improvement activities need a toolbox of methods to collect and analyze data. The IHI website serves as an excellent resource for detailed descriptions of several QI tools. 7 Tools can generally be subdivided into 2 categories: (1) tools that delineate problems and (2) tools to assess possible solutions to those problems.

Tools for Delineating Problems

Example: Cause and effect/fishbone diagram to identify barriers for discharging patients on naloxone (Van et al). 8

Tools for Assessing Solutions

QI assessment and interventions can be done by scrutiny of single cases or by analyzing general trends.
