The purpose of this study was to examine the relationship between Health Action Process Approach (HAPA) postintentional constructs (maintenance self-efficacy, recovery self-efficacy, action planning, coping planning) and medication adherence among phase II cardiac rehabilitation (CR) patients. Purposive sampling was used to recruit 91 phase II CR patients age 50 years and over. All respondents completed paper and pencil questionnaire examining HAPA postintentional constructs (action planning, coping planning, maintenance self-efficacy, recovery self-efficacy), medication adherence, and demographic characteristics. Validity and reliability were confirmed for all scales included in the questionnaire. Descriptive statistics were used to describe respondents’ characteristics. Bivariate statistics (correlation, Mann-Whitney U-test, Kruskal Wallis test) were used to examine associations between medication adherence and each HAPA postintention construct as well as medication adherence and respondent demographic characteristics. Better medication adherence was associated with greater maintenance self-efficacy (r = −.290, p = .006) and better action planning skills (r = −.233,p = .027) and coping planning skills (r = −.277,p = .008) as indicated by higher scores on the maintenance self-efficacy, action planning, and coping planning scales. There was no significant linear relationship between medication adherence and recovery self-efficacy (r = −.103,p = .335) or medication adherence and any of the respondents’ demographic characteristics (p > .05). Only maintenance self-efficacy remained significant in a multivariate model predicting medication adherence. Greater maintenance self-efficacy was associated with increased medication adherence; health professionals working in CR settings might consider opportunities to enhance maintenance self-efficacy for medication adherence. Additional research is needed to identify strategies for promoting maintenance self-efficacy for medication adherence. [ABSTRACT FROM AUTHOR]

Isocyanates, the essential cross-linking chemicals used to make polyurethane, are potent sensitizers and a common cause of occupational asthma. In addition, isocyanate (NCO) skin contact may contribute to the development of isocyanate asthma. Prior work has shown that unbound NCO can persist on recently spray coated auto body parts after appearing dry. The purpose of this study was to assess whether isocyanate skin exposure can result from handling such surfaces. Quantitative surface and skin wipe sampling for total NCO was performed on test panels sprayed with aliphatic isocyanate coatings, and on paired skin samples obtained from participants who had rubbed the recently dried surfaces. Surface and skin samples, obtained from 18 workers in five auto body shops, were prepared following NIOSH method 5525 (modified for skin samples), and isocyanate species derived from hexamethylene diisocyanate and isophorone diisocyanate were analyzed using high-performance liquid chromatography with ultraviolet and fluorescence detectors. Quantifiable unbound NCO species were detected on 84.2% of all sprayed surfaces sampled after initially considered dry. Only 7 out of a total of 104 (6.7%) non-compounded skin samples obtained after contact with the recently dried coatings had detectable quantities of free NCO. The 7 positive samples, all obtained at the initial sampling time (t0), had a geometric mean of O. 016 µg NCO cm-2 (range: 0.002-0.88 µg NCO cm-2). Only I of 12 (8.3%) of skin samples obtained after compounding contained detectable free NCO. The risk of substantial human isocyanate skin exposure from contact with the dry appearing (yet not fully cured) isocyanate coatings evaluated in this study appears to be low, although other isocyanate coatings and tasks may pose a greater risk of NCO skin exposure.
