What determines the possession of assistive devices among patients with rheumatic diseases? The influence of the country-related health care system

Assistive devices, home adjustments and external help in rheumatoid arthritis

PURPOSE

To explain the determinants of adaptation with disease and self-management of patients with rheumatoid arthritis (RA) in Estonia, focusing on the use of assistive devices, home adjustments and the need for external help.

METHOD

A random sample (n = 1259) of adult Estonian RA patients was selected from the Estonian Health Insurance Fund Database. The patients completed a self-administered questionnaire, which included information about their socio-demographic and disease characteristics, the costs of care, quality of life, use of assistive devices, home adjustments and the need for external help. Regression analysis was used to analyse the predictors of patient's adaptation with disease and self-management.

RESULTS

Twenty-six percent of the respondents used assistive devices, 20% had made home adjustments and 37% needed external help. Disabilities and physical impairments predicted the use of assistive devices, home adjustments and the need for external help. The use of medical rehabilitation services predicted the less frequent use of assistive devices, while female gender and single status predicted a more expressed need for external help.

CONCLUSIONS

Disability and physical impairment are the most important determinants of the use of various technical aids and home adjustments. These factors, along with the female gender and single status of the patient, predict help-dependence.

Assessment of canes used by older adults in senior living communities

The purpose of this cross-sectional study is to provide basic but essential information about how older cane users obtain their canes and how they use these canes for their daily mobility, since there is still lack of information on these areas. Ninety-three older (≥65 years old) subjects who use canes for daily activities were recruited from four assisted living facilities and five retirement centers for this cross-sectional study. The assessment involved interviewing cane users with a questionnaire, examining their canes, and investigating how these canes were used by their owners during ambulation. The commonly used canes are (from most to least): adjustable single-tip, un-adjustable (wooden), small quad, and large quad. Five major problems from data analysis were identified: lack of medical consultation for device selection/use, incorrect cane height/maintenance, placement of cane in improper hand, inability to maintain the proper reciprocal gait pattern, and improper posture during ambulation. Only forward-leaning posture during ambulation might be associated with increased falls among the older cane users. Knowledge of these problems could assist health professionals to implement appropriate interventions in clinical settings and to provide community service to address all problems related to cane use.

Assistive technology for rheumatoid arthritis

BACKGROUND

Provision of assistive technology is a widely used intervention for people with rheumatoid arthritis. Assistive technology is any item used to increase or maintain functional ability in individuals with disabilities. It includes a wide range of products, from low-technology devices to technologically complex equipment. Yet, there are few systematic reviews on the effectiveness of assistive technology in this population.

OBJECTIVES

To assess the benefits of assistive technology for adults with rheumatoid arthritis in terms of improving functional ability and reducing pain, and to assess potential adverse effects in terms of psychological discomfort, personal injury or material damage related to device use.

SEARCH STRATEGY

We searched the following databases: CENTRAL (The Cochrane Library), MEDLINE, EMBASE, CINAHL, AMED, ISI Web of Science, PEDro, and OTseeker (to October 2008). In addition, we scanned reference lists, sought grey literature, and had personally communicated with authors. We updated the literature searches in January 2009.

SELECTION CRITERIA

Included study designs were randomised controlled trials, clinical controlled trials, controlled before and after studies, and interrupted time series where the effectiveness of assistive technology was evaluated. In addition, comparative observational studies were included if addressing adverse effects.

DATA COLLECTION AND ANALYSIS

Two authors independently selected trials, extracted data, and assessed study quality. Investigators were contacted to obtain missing information.

MAIN RESULTS

Only one randomised controlled trial with 29 participants was included. The study compared the use of an eye drop device to a standard bottle in people with rheumatoid arthritis suffering from persistent dry eyes. The study was considered to have low quality of evidence. The proportions with observed difficulties when using the device to squeeze out drops and getting the drops in the eyes were 10% and 14%, respectively. This compared to 52% and 52% when using the standard bottle (P = 0.001; P = 0.003, respectively). The proportions of participants reporting difficulties with squeezing the bottle, controlling the number of drops, and aiming the drops when using the device were 40%, 44%, and 46% respectively, while using the standard bottle the proportions with difficulties were 72%, 84%, and 76% (P = 0.001; P = 0.003; P = 0.031, respectively).

AUTHORS' CONCLUSIONS

Only one trial met the inclusion criteria for this review. Thus, there is very limited evidence for the effect of assistive technology for adults with rheumatoid arthritis and, therefore, an urgent need for high-quality research addressing the effectiveness of commonly used interventions.

Rehabilitation in musculoskeletal diseases

Occupational therapy and vocational rehabilitation are increasingly available for people with musculoskeletal diseases. Occupational therapy aims to improve or maintain function in work, leisure, self-care and domestic activities, social roles, and psychological status. A wide range of interventions is provided, including joint protection, assistive devices and splints. Vocational rehabilitation aims to improve ability to stay in or return to work. Comprehensive occupational therapy and some interventions (joint protection, assistive devices and splints), as well as vocational rehabilitation, are reviewed. There is moderate to good evidence for effectiveness of comprehensive occupational therapy in rheumatoid arthritis, and for joint protection and splints in rheumatoid arthritis and osteoarthritis. However, evidence for other aspects of occupational therapy is still scarce, and better-quality trials are needed. Vocational rehabilitation to prevent job losses in rheumatic diseases is effective, but once people are unemployed, return-to-work interventions are less successful. Evidence is moderate to good for work conditioning programmes using a cognitive behavioural approach in chronic low-back pain, and also for early return-to-work interventions in subacute low-back pain.

Assistive devices: usage in patients with rheumatoid arthritis

We describe the usage of various assistive devices and identify factors associated with usage in patients with rheumatoid arthritis (RA). A cross-sectional, multicentre study was performed in three outpatient rheumatology clinics in the Netherlands. Two hundred forty patients with RA participated in the study. The main measures were questionnaires and a semi-structured interview regarding the possession and usage of 21 common assistive devices in the ISO9999 categories orthopaedic footwear, personal care, mobility, household and adaptations for housing. Potential factors associated with usage included sociodemographic variables, health status, quality of life, coping strategies, self-efficacy, outcome expectations and satisfaction. Out of 240 patients, 213 (89%) had one or more assistive devices in possession (median number of devices 3.0, interquartile range 3.0). The proportions of patients never using a device in possession varied between 8% for orthopaedic insoles and 23% for grab bars. The main factors related to usage varied among categories, but common determinants were a specific impairment or disability, satisfaction with the device or related services, self-efficacy and the number of devices in possession. In conclusion, in patients with RA, possession rates are high, with 23% or less of the devices in possession being abandoned. Overall, satisfaction rates were high. Factors associated with usage varied among categories and comprised, apart from the number of devices in possession and variables related to health status, also aspects of satisfaction with the device or related services or self-efficacy. The latter findings underline the need for a systematic evaluation of the outcomes of assistive devices by prescribing health professionals or suppliers in every individual case.

Rheumatoid arthritis in Lithuania: need for external help from the onset of disease

PURPOSE

To estimate the burden of rheumatoid arthritis (RA) in Vilnius, Lithuania, the former socialist country in Eastern Europe, in terms of patients' need for help from other persons and to explore the factors which influence the need for physical help.

METHOD

Some 537 patients with RA, registered in Vilnius, answered questions about socio-demographics, disease characteristics, categories of required help, the use of major appliances and adaptations, underwent a clinical examination and filled in the modified health assessment questionnaire (MHAQ) and arthritis impact measurement scale (AIMS). Logistic regression was used to assess which variables from those explored influenced the need for physical help.

RESULTS

A total of 230 (42.9%) patients out of 537 were requiring help from other persons, and the proportion was equally high in all the disease duration categories. A quarter of the patients (25.1%) were classified to ACR III and IV functional impairment groups. In multivariate logistic regression model the risk to become dependent on external help ultimately depended on MHAQ (10.32 [CI 95% 6.57; 16.23], p < 0.001) but the use of joint stabilization measures (1.97 [CI 95% 1.06; 3.64], p < 0.01) and 28 tender joints count (1.02 [CI 95% 1.0; 1.06], p < 0.05) were also important.

CONCLUSIONS

Nearly half of the patients reported being dependent on others and a quarter of patients were in definite need for that. The functional impairment is the most important risk factor, although identifying the group using joint stabilization measures routinely may be of practical value in order to define the risk group which may need the external help in future.
