Performance of health status measures with a pen based personal digital assistant.

BACKGROUND: Increasing use of self reported health status in clinical practice and research, as well as patient appreciation of monitoring fluctuations of health over time, suggest a need for more frequent collection of data. Electronic use of health status measures in the follow up of patients is a possible way to achieve this. OBJECTIVE: To compare self reported health status measures in a personal digital assistant (PDA) version and a paper/pencil version for test-retest reliability, agreement between scores, and feasibility. METHODS: 30 patients with stable rheumatoid arthritis (mean age 61.6 years, range 49.8 to 70.0; mean disease duration, 16.7 years; 63% female; 67% rheumatoid factor positive; 46.6% on disease modifying antirheumatic drugs) completed self reported health status measures (pain, fatigue, and global health on visual analogue scales (VAS), rheumatoid arthritis disease activity index, modified health assessment questionnaire, SF-36) in a conventional paper based questionnaire version and on a PDA (HP iPAQ, model h5450). Completion was repeated after five to seven days. RESULTS: Test-retest reliability was similar, as evaluated by the Bland-Altman approach, the coefficient of variation, and intraclass correlation coefficients. The scores showed acceptable agreement, but with a slight tendency to higher scores on VAS with the PDA than the paper/pencil version. No significant differences were seen for measures of feasibility (time to complete, satisfaction score), but 65.5% preferred PDA, 20.7% preferred paper, and 13.8% had no preference. CONCLUSIONS: The clinimetric performance of paper/pencil versions of self reported health status measures was similar to an electronic version, using an inexpensive PDA.

Seven year changes in health status and priorities for improvement of health in patients with rheumatoid arthritis.

OBJECTIVES: To examine possible changes in priorities for improvement in health and health status from 1994 to 2001 within the setting of the Oslo Rheumatoid Arthritis (RA) Register, which provides representative data for the entire RA population in the county. METHODS: All living patients in the Oslo RA Register area received a postal questionnaire in 1994 and 2001, including the Arthritis Impact Measurement Scales 2 (AIMS2), Short Form-36, the modified Health Assessment Questionnaire, and pain and fatigue visual analogue scales (VAS). Priorities for improvement in health were examined through question 60 in AIMS2, where patients are asked to indicate three of 12 areas of health where they would most like to see improvement. RESULTS: The number of respondents aged 20-79 years in 1994/2001 was 932/830, with similar demographic characteristics (78.8/78.3% were female, mean age 60.6/60.8, and disease duration 12.6/13.9 years). Health status was improved in all dimensions, with statistical improvement for the physical dimension, global health and pain, from 1994 to 2001. The profile of priorities remained mostly unchanged. Improvement in pain had the highest priority in both cohorts. Both symptom modifying and disease modifying drugs were more extensively used in 2001. CONCLUSIONS: Health status had improved from 1994 to 2001, probably because of access to better and more aggressive treatments. Pain remained the area of highest priority for improvement among patients with RA-despite an improved level of pain in 2001.

Peptide-containing fractions in depression.

A mixture of peptides and glycoproteins has been found in benzoic acid-precipitable material from urines of psychomotorically agitated and retarded endogenous depressive patients. This complex mixture of compounds is fractionated on a Sephadex G-25 gel, from which the different peaks are further separated on Biogel P2. The G-25 elution profiles ultraviolet absorbance, 280 nm) from depressive patients deviated from the normal pattern. The increase in hydrolyzable ninhydrin-colorable material of the P2 fractionation step encountered in psychotic depression was several-fold that of the normal population. Neurochemically active peptide-containing fractions were found. As explanation of these findings, it is probable that a genetically determined peptidase insufficiency is present, causing a peptide overflow when the secretion outstrips the breakdown. This model could easily combine more psychodynamic models with the genetic-biological models. The variability of the peptide patterns could possibly reflect the considerable clinical variability of the syndrome. Furthermore, the presence of a group of active compounds with different neuropharmacological activities might reflect the composite nature of the depressive syndrome.
