    ABSTRACT: To assess the effects of additional information based nursing care program in the treatment of asthma and COPD patients at a pulmonary outpatient clinic. In a double blind, randomized clinical trial, 191 patients were allocated to an additional care group or control group. Patients in the intervention group received a protocol-based education program on individual basis by a pulmonary nurse on individual basis (average duration 60 min per patient). All patients were masked for the trial objectives. Effectiveness was expressed in terms of knowledge, inhalation technique, self-management, exacerbation rate (primary outcomes), and health-related quality of life and satisfaction with care received (secondary outcomes). The time interval between the initial and final assessments was 6 months. Ninety-seven patients were randomized into the additional care group and 94 into the control group, of which 157 had a complete dataset. (Un)adjusted analyses did not show differences between treatment groups in terms of knowledge, inhalation technique, self-management, health-related quality of life, and satisfaction with care. Multivariate logistic regression adjusting for baseline covariates showed a significant treatment effect with regard to exacerbation rate (odds ratio=0.35; 95% confidence limits: 0.13/0.94, p=0.04). With the exception of exacerbation rate, we could not demonstrate efficacy of additional nursing care in a broad range of outcome parameters. At present we do not recommend to implement our patient-tailored education program in daily practice.

    ABSTRACT: Inhalation medication is essential in the treatment of asthma and chronic obstructive pulmonary disease (COPD) patients. Incorrect inhalation technique reduces the effects of medication and has been reported to range from 22% to 95% from optimal. The objective of this study was to determine inter- and intraobserver reliability in inhalation technique assessment. For interobserver reliability three observers scored after three times viewing a total of 49 video recorded inhalation demonstrations using device-specific checklists and mutually agreed scoring rules. Intraobserver reliability was assessed for two observers after 8 months by scoring inhalation demonstrations a second time. Both inter- and intraobserver reliability were expressed by mean percent agreement and mean Kappa scores. All inhaler devices revealed a high mean percent agreement and a substantial or almost perfect Kappa scoring for both inter- and intraobserver reliability. Only one item, "exhale to residual volume," showed poor intraobserver reliability. Assessment of video recorded inhalation technique using device-specific checklists, triple viewing, and mutual agreed scoring rules is reliable. This method enables blind observation of inhalation technique.
