Development and evaluation of an appraisal form to assess clinical effectiveness of adult invasive mechanical ventilation systems

Abstract

BackgroundRapid developments in intensive care medicine have made mechanical ventilation an essential method in the resuscitation and comprehensive treatment of critical care patients. This study aimed to develop and evaluate an appraisal form assessing the clinical effectiveness of adult invasive mechanical ventilation systems.MethodsAn appraisal form was designed according to the effectiveness evaluation theory of the American Weapons Systems Effectiveness Industry Advisory Committee (WSEIAC) along with literature review and expert panel review. Content validity of the preliminary form was analyzed in a cohort of 200 patients. Exploratory and confirmatory factor analysis was used to assess appraisal form validity. Discriminate validity of different ventilation outcomes was analyzed by t test. Test/retest reliability and inter-scorer reliability were evaluated with 30 patients after a 2-week interval by Cronbach's alpha.ResultsExploratory factor analysis showed eigenvalues for 3 dimensions (availability, dependability, capability) to be 7.85, 4.43, and 4.22, respectively. Cronbach’s α for internal consistency of the appraisal form was 0.957, and 0.922, 0.961 and 0.937, respectively, for the 3 dimensions. Test-retest reliability of 3 dimensions was 0.976, and 0.862, 0.857, 0.885, respectively. Intra-class correlation coefficient verified test-retest reliability; ICC 0.976 and 0.862, 0.857, 0.885 for 3 dimensions, respectively.ConclusionsThe appraisal form for clinical effectiveness of adult invasive mechanical ventilation systems has high reliability and validity and may be used in clinical setting.

Effectiveness of Self-instructional Module on Nurses’ Performance Regarding Caring of Patient with Acute Respiratory Distress during Covid-19 Outbreaks

“…The items on this sheet were adapted from Abdollahi et al (2020), it included 4 mean dimensions (Nature of the disease (9 items), transmission of the disease (3 items), actions in dealing with suspected, probable and confirmed cases (19 items), precautionary measures by health care providers (6 items), treatment of the disease (5 items)).Scoring system: The total score of nurses' knowledge was equal 51; (1) grade were given to the correct answer and (zero) to the incorrect answer. Total score was considered as the following: ≥ 80% was considered satisfactory level of knowledge (> 41 grades correct answer). ˂ 80% was considered unsatisfactory level of knowledge (< 41 grades correct answer).B-Nurses' practical observational checklists: It were adopted fromLi, Chen and Li, (2012) to evaluate an effectiveness appraisal form for assessing adult invasive mechanical ventilation systems (EAP-AIMVS), and to apply it for measuring the effectiveness of nursing staff in establishing artificial airways and helping to wean patients from mechanical ventilation…”
