Strength of Recommendations

A –There is strong evidence that occupational therapy practitioners should routinely provide the intervention to eligible clients. Good evidence was found that the intervention improves important outcomes and concludes that benefits substantially outweigh harm.

B –There is moderate evidence that occupational therapy practitioners should routinely provide the intervention to eligible clients. There is high certainty that the net benefit is moderate, or there is moderate certainty that the net benefit is moderate to substantial.

C –There is weak evidence that the intervention can improve outcomes. It is recommended that the intervention be provided selectively on the basis of professional judgment and patient preferences. There is at least moderate certainty that the net benefit is small.

I –There is insufficient evidence to determine whether or not occupational therapy practitioners should be routinely providing the intervention. Evidence that the intervention is effective is lacking, of poor quality, or conflicting and the balance of benefits and harm cannot be determined.

D –It is recommended that occupational therapy practitioners not provide the intervention to eligible clients. At least fair evidence was found that the intervention is ineffective or that harm outweighs benefits.

Methodology

Methods Used to Collect/Select the Evidence

Hand-searches of Published Literature (Primary Sources)
Hand-searches of Published Literature (Secondary Sources)
Searches of Electronic Databases

Description of Methods Used to Collect/Select the Evidence

Search terms for the reviews were developed by the methodology consultant to the American Occupational Therapy Association, Inc. (AOTA) Evidence-Based Practice Project (EBP) and AOTA staff in consultation with the review author and reviewed by the advisory group. The search terms were developed not only to capture pertinent articles but also to make sure that the terms relevant to the specific thesaurus of each database were included. Table C2 in the original guideline document lists the search terms related to the population and intervention included in the systematic review. A medical research librarian with experience in completing systematic review searches conducted all searches and confirmed and improved the search strategies.

Databases and sites searched included MEDLINE, PsycINFO, CINAHL, AgeLine, OTseeker, and Scopus. In addition, consolidated information sources, such as the Cochrane Database of Systematic Reviews, were included in the search. These databases are peer-reviewed summaries of journal articles and provide a system for clinicians and scientists to conduct evidence-based reviews of selected clinical questions and topics. Moreover, reference lists from articles included in the systematic reviews were examined for potential articles, and selected journals were hand searched to ensure that all appropriate articles were included.

Inclusion and exclusion criteria are critical to the systematic review process because they provide the structure for the quality, type, and years of publication of the literature incorporated into a review. The systematic review was limited to peer-reviewed scientific literature published in English. The intervention approaches examined were within the scope of practice of occupational therapy. The literature included in the review was published between 1990 and July 2011 and included study participants ages 18 years or older with health conditions that affected function. Studies included in the review are Levels I, II, and III evidence. The review excluded data from presentations, conference proceedings, non–peer-reviewed research literature, dissertations, and theses.

A total of 6,762 citations and abstracts were included in the review. The first author of this practice guideline completed the first step of eliminating references on the basis of citation and abstract. The systematic review was carried out as academic partnerships in which an academic faculty member worked with two graduate students. The review teams completed the next step of eliminating references on the basis of citations and abstracts. The full-text versions of potential articles were retrieved, and the review team determined final inclusion in the review on the basis of predetermined inclusion and exclusion criteria.

Number of Source Documents

A total of 35 articles were included in the final review. The review included 26 Level I studies, 3 Level II studies, and 6 Level III studies.

Methods Used to Analyze the Evidence

Review of Published Meta-Analyses
Systematic Review with Evidence Tables

Description of the Methods Used to Analyze the Evidence

The teams working on the focused question reviewed the articles according to their quality (scientific rigor and lack of bias) and levels of evidence. Each article included in the review was then abstracted using an evidence table that provides a summary of the methods and findings of the article and an appraisal of the strengths and weaknesses of the study on the basis of design and methodology. American Occupational Therapy Association Inc. (AOTA) staff and the Evidence-Based Practice (EBP) Project consultant reviewed the evidence table to ensure quality control. All studies are summarized in full in the evidence table in Appendix D in the original guideline document.

Limitations of the studies incorporated into the review may include small sample sizes, lack of blinding, a high rate of attrition, and limited details on the intervention provided in a given study. Also, in a multicomponent treatment intervention, it is difficult to separate the role of home modification. In several studies there is lack of a control group and lack of randomization. In addition, contamination may have taken place in several studies, as a similar intervention may have been inadvertently provided to the control group.

Methods Used to Formulate the Recommendations

Expert Consensus

Description of Methods Used to Formulate the Recommendations

A major focus of American Occupational Therapy Association (AOTA)’s Evidence-Based Practice (EBP) projects is an ongoing program of systematic review of multidisciplinary scientific literature, using focused questions and standardized procedures to identify practice-relevant evidence and discuss its implications for practice, education, and research. An evidence-based perspective is founded on the assumption that scientific evidence of the effectiveness of occupational therapy intervention can be judged to be more or less strong and valid according to a hierarchy of research designs, an assessment of the quality of the research, or both. AOTA uses standards of evidence modeled on those developed in evidence-based medicine. This model standardizes and ranks the value of scientific evidence for biomedical practice using the grading system based on the work of Sackett et al. (1996) and presented in the “Rating Scheme for the Strength of the Evidence” field of this summary. In this system, the highest level of evidence, Level I, includes systematic reviews of the literature, meta-analyses, and randomized controlled trials (RCTs). In RCTs, participants are randomly allocated to either an intervention or a control group, and the outcomes of both groups are compared. Other levels of evidence include Level II studies, in which assignment to a treatment or a control group is not randomized (cohort study); Level III studies, which do not have a control group; Level IV studies, which use a single-case experimental design, sometimes reported over several participants; and Level V studies, which are case reports and expert opinion that include narrative literature reviews and consensus statements.

The systematic review of home modifications was supported by AOTA as part of the EBP Project. AOTA is committed to supporting the role of occupational therapy in this area of practice on the basis of the importance to older adults of aging in place and an interest in updating the Occupational Therapy Practice Guidelines for Home Modification (Siebert, 2005). The systematic review was also developed on basis of the need for occupational therapy practitioners to have access to the results of the latest and best available literature to support intervention within the scope of occupational therapy practice.

One focused question served as the basis for the systematic review: What is the evidence for the effectiveness of home modification interventions within the scope of occupational therapy for adults and older adults to participate in areas of occupation in the home and community? This question was reviewed by the review author, an advisory group of experts in the field, AOTA staff, and the methodology consultant to the AOTA EBP Project. The areas of occupation include activities of daily living (ADLs), instrumental activities of daily living (IADLs), work, education, leisure, and social participation.
