PCA can therefore be used to optimize the design of future clinical studies though highlighting the key behavioural tests of relevance and thereby minimizing the required amount of data collection.
However, most studies have found high correlations between scores obtained from these different modes of data collection and that the clinical relevance of found discrepancies are generally negligible (e.g., [ 28- 31]).
Most indicators were rated highly on link to outcomes, reliability, relevance, actionability and priority but rated more poorly on feasibility of data collection under routine conditions.
Indeed, the relevance of a medical survey is largely dependent on two main steps: the quality of data collection in the medical-charts and the fidelity of data transferring from the charts to the electronic system.
Respondents were asked to rate each QI adopting the RAND Appropriateness Methodology (scales 1 9, 1=extremely inappropriate; 9=extremely appropriate), according to the selection criteria of relevance, scientific soundness (validity, reliability, comparability) and feasibility (precise definition and specification, data feasibility, reliability of data collection).
Quality and relevance were assessed using the following domains: the research focus; caregiver status (bereaved/current); relationship to cared-for person; methods of data collection; population; country of origin; theoretical framework and key findings.
Another frequent complaint was about the lack of data collection.
There's a lot of data collection to be done".
Before data collection, the enumerators were trained on the techniques of data collection and the questionnaire was pre-tested on ten households to evaluate the appropriateness of the design, clarity, and interpretation of the questions, relevance of the questions, and time taken for an interview.
Multiple methods of data collection were adopted.
