Standardized on-road tests assessing fitness-to-drive in people with cognitive impairments: A systematic review

Application of the Person-Environment-Occupation-Performance Model: A Scoping Review

The Person-Environment-Occupation-Performance (PEOP) Model is one of several occupation-based models in occupational therapy. The model describes the transactional nature of person, environment, and occupation factors that support performance (doing), participation (engagement), and well-being (health and quality of life). The purpose of this study was to explore the extent and nature of evidence on the PEOP Model. We used a scoping review to identify and analyze journal articles that used the PEOP Model as a framework for study. The PRISMA extension for scoping reviews (PRISMA-ScR) criteria were used to develop the research methods. We found 109 articles that adopted the PEOP Model as an organizing framework. The studies reviewed represent the breadth of occupational therapy practice and the transactional nature of person, environment, occupation, and performance in the PEOP Model. The PEOP Model is a useful international framework for research and practice across populations, conditions, life circumstances, settings, and areas of practice.

Does aphasia impact on return to driving after stroke? A scoping review

PURPOSE

Stroke can affect driving, an important activity of daily living. Little is known about whether aphasia (language impairment) impacts driving post-stroke. This scoping review explores impacts and perceived impacts of aphasia on driving performance, and the process of returning to driving post-stroke.

MATERIALS AND METHODS

Scoping review using Arksey and O'Malley's framework, reported using the Preferred Reporting Items for Systematic reviews and Meta-Analyses extension for Scoping Reviews (PRISMA-ScR). Bibliographic databases were searched and international clinical practice guidelines were sourced online. Full-text articles were independently assessed by two reviewers. Results were tabulated and summarised using narrative synthesis.

RESULTS

Forty-three literature sources and 17 clinical practice guidelines were identified. Six studies investigated return to driving with aphasia post-stroke; 37 sources from the broader literature contributed to objectives. It remains unclear whether aphasia impacts fitness-to-drive; however, people with aphasia face barriers in returning to driving due to: (1) uncertainty regarding the role of language in driving; (2) poor awareness and knowledge of aphasia, and (3) communication demands in the patient-journey and assessment.

CONCLUSIONS

The current evidence base is limited, inconsistent, and lacking in quality and recency and there is a lack of guidelines to support clinical practice. People with aphasia face barriers in returning to driving; however, it is unclear if aphasia affects fitness-to-drive post-stroke. Implications for rehabilitationPeople with aphasia, their caregivers and clinicians have identified return to driving as a top 10 research priority.We do not know if aphasia affects fitness-to-drive post-stroke, but communication difficulties can make the process of returning to driving more difficult.Speech pathologists have an important role in ensuring that driving is discussed with people with aphasia post-stroke.Speech pathologists should support the multidisciplinary team to understand and meet the communication needs of people with aphasia throughout the driving evaluation process.

Performance Analysis of Driving Ability (P-Drive): Investigating Construct Validity and Concordance of Australasian Data

On-road assessment is optimal for determining medical fitness-to-drive but unreliable if determined by global pass/fail decisions alone. Occupational therapists need standardized, psychometrically sound on-road scoring procedures. Performance Analysis of Driving Ability (P-Drive) is a promising on-road test developed in Sweden, but it has not been standardized for Australasia. We investigated the psychometric properties and concordance with an on-road decision of data gathered with the Australasian version of P-Drive. P-Drive was administered to older and cognitively impaired drivers (N = 134) aged 18 to 91 years (mean age 68) who were referred to 10 driving clinics in Australia and New Zealand to determine driving performance. Rasch analysis provided evidence for construct validity and concordance of the data gathered. An optimal cut-off score of 85 was set, yielding evidence of good sensitivity at 88% and specificity at 88%. The Australasian version of P-Drive produces valid and reliable data regarding on-road driving performance.

Using Serial Trichotomization to Determine Fitness to Drive in Medically At-Risk Drivers

IMPORTANCE

Clinical tests that identify fit and unfit drivers with 100% sensitivity and specificity would reduce uncertainty and improve efficiency of occupational therapists performing comprehensive driving evaluations (CDEs).

OBJECTIVE

To examine whether serial trichotomization of clinical tests predicts pass-fail outcomes with 100% sensitivity and specificity in a sample of medically at-risk drivers and in drivers with and without cognitive impairment (CI) referred for a CDE.

DESIGN

Retrospective data collection and analysis of scores on the Montreal Cognitive Assessment; Trail Making Test, Part A and Part B; and the Useful Field of View® Subtests 1 to 3 and outcomes on the CDE (pass-fail or indeterminate requiring lessons and retesting). Receiver operating characteristic curves of clinical tests were performed to determine 100% sensitivity and specificity cut points in predicting CDE outcomes. Clinical tests were arranged in order from most to least predictive to identify pass-fail and indeterminate outcomes.

SETTING

A driving assessment clinic.

PARTICIPANTS

Among 142 medically at-risk drivers (M age = 69.2 yr, SD = 14.1), 66 with CI, 46 passed and 39 failed the CDE; 57 were indeterminate.

OUTCOMES AND MEASURES

On-road pass-fail outcomes.

RESULTS

Together, the six clinical tests predicted 62 pass and 49 fail outcomes in the total sample; 21 pass and 34 fail outcomes in participants with CI; and 58 pass and 14 fail outcomes in participants without CI.

CONCLUSIONS AND RELEVANCE

Serial trichotomization of clinical tests increases the accuracy of making informed decisions and reduces the number of drivers undergoing unnecessary on-road assessments. Plain-Language Summary: Clinical tests and their cut points that identify fit and unfit drivers vary substantially across settings and research studies. Serial trichotomization is one method that could help control for this variation by combining clinical test scores showing 100% sensitivity and specificity to identify pass (fit drivers) and fail outcomes (unfit drivers) and to reduce the number of drivers undergoing unnecessary on-road assessments.

Evaluation of Psychophysical Fitness in Drivers over 65 Years of Age

BACKGROUND

The deterioration of cognitive and psychophysical ability associated with aging has an effect on road safety, especially in the driving of vehicles. The current study's main objective is to evaluate the psychophysical aptitudes in drivers over 65 years of age in a sample of drivers in Spain.

METHODS

The sample was formed of a total of 1663 drivers who attended a Driver Recognition Center. The evaluation of their psychophysical aptitudes was carried out following the Medical-Psychological Exploration Protocol for Driver Recognition Centers, edited by the Ministry of Health and the General Directorate of Traffic.

RESULTS

The results show increased restrictions in the evaluation of driving ability with age, which are especially significant after 75 years of age. Regarding sex, 70.1% of women have an approved evaluation, compared to men aged between 65-69, although from 69 onwards, the percentage of approved women decreases significantly. The loss of visual capabilities and poor performance in psycho-technical tests are the main causes associated with an evaluation with restrictions, with the number of restrictive conditions increasing with age.

CONCLUSIONS

There is an increase in the number of cases with age-related restrictions, especially in the case of women and ophthalmologic-related problems, although the majority of drivers over 65 years old continue driving, thus continuing with a practice that has been related to the well-being and quality of life of older adults.

Driving Errors Predicting Pass/Fail On-Road Assessment Outcomes Among Cognitively Impaired Older Drivers

Older drivers with cognitive impairment (CI)/dementia make significantly more driving errors than healthy controls; however, whether driving errors are predictive of pass/fail outcomes in older drivers with CI/dementia are unclear. This study determined the driving errors that predicted failing an on-road assessment in drivers with CI. We retrospectively collected comprehensive driving evaluation data of 80 participants (76.1 ± 9.3 years) from an Ontario driving assessment center. Adjustment to stimuli (area under the curve [AUC] = 0.88), lane maintenance (AUC = 0.84), and speed regulation errors (AUC = 0.85) strongly predicted pass/fail outcomes. Worse performance on the Trails B (time) and Useful Field of View® (Subtest 2, Subtest 3, and risk index) were significantly correlated with adjustment to stimuli (p < .05), lane maintenance (p < .05), and speed regulation errors (p < .05). Adjustment to stimuli, lane maintenance, and speed regulation errors may be critical indicators of failing an on-road assessment in older drivers with CI. Prioritizing these errors may help identify at-risk drivers.

Self-awareness predicts fitness to drive among adults referred to occupational therapy evaluation

Background

Driving is associated with independence, well-being, quality of life, and an active lifestyle. Driving requires cognitive, motor, and visual skills, including self-awareness and processing speed. This study examines whether driver self-awareness, motor processing speed, and cognitive processing speed can predict fitness to drive among individuals referred to occupational therapy evaluation due to concerns about their driving ability.

Method

In this cross-sectional study, 39 participants were referred to off- and on-road driving evaluation to determine their fitness to drive due to changes in health status, advanced age, license renewal requirement, or prior automobile accidents. A registered occupational therapist (OT) classified 23 of the participants as fit to drive and 16 as unfit to drive. Motor and cognitive processing speed were assessed by the Stationary Perception-Reaction Timer and the Color Trails Test, respectively. Driving self-awareness was assessed by comparing the DI and OT evaluations to the participants' estimation of their own on-road driving performance.

Results

The fit-to-drive participants had a better motor and cognitive processing speed than those unfit-to-drive. The unfit-to-drive group overestimated their driving ability, whereas the fit-to-drive group accurately or almost accurately estimated their driving ability. Driving self-awareness was a significant predictor of participants' fitness to drive.

Conclusions

This study demonstrates the importance of self-awareness for predicting fitness to drive among people at risk for compromised driving skills. Thus, driving self-awareness should be addressed as part of fitness-to-drive evaluations and interventions.

Evaluating traditional Chinese medicine diagnostic instruments for functional dyspepsia: systematic review on measurement properties

Background

Pattern diagnosis-guided treatments in Traditional Chinese Medicine (TCM) has been recognised by the eleventh revision of the International Classification of Diseases (ICD-11). Accurate pattern diagnosis requires reliable and valid diagnostic instruments that guide the collection of TCM clinical data without bias. This study synthesised the existing TCM diagnostic instruments for functional dyspepsia (FD) and appraised their quality regarding their development process and measurement properties.

Methods

Seven electronic databases were searched for validation studies on TCM diagnostic instruments for FD. Synthesis and appraisal of the included studies were performed following the COSMIN (COnsensus-based Standards for the selection of health Measurement INstruments) Initiative guidelines adapted for TCM diagnostic instruments. Risk of bias assessment was conducted using the COSMIN Risk of Bias Checklist.

Results

Five studies were included, with five unique TCM diagnostic instruments for FD identified. All five diagnostic instruments were of inadequate quality in terms of their development process, implying a shortcoming in their relevance, comprehensibility, and comprehensiveness. Only the criterion validity of Stomach Qi Deficiency Pattern Assessment Scale was of sufficient quality and had no risk of bias in its validation.

Conclusion

The quality of TCM diagnostic instruments for FD warrants urgent improvements. None of them was considered reliable or valid for guiding TCM pattern diagnosis. To support the evidence base of the standardization of TCM patterns in ICD-11, TCM diagnostic instruments should be developed and validated rigorously under the COSMIN guidelines. Amendments should be made on the guidelines to accommodate the features and uniqueness of TCM diagnostic process.
