They may also be attributed in part to different data collection timeframes, i.e., El Cuete Phase I data was collected in 2004 while El Cuete Phase III qualitative data were collected between October 2006 and January 2008.
Since the delivery of the IDOCC program was staggered in the stepped wedge implementation approach, the baseline data collection timeframes varied among steps: Step I: 2007-2008, Step II: 2008-2009, and Step III: 2009-2010.
In cases where a practice shifted from one group to another during the baseline data collection timeframe, we assigned that practice to the group in which they spent the majority of the year in.
Typically, per UMUC3 nucleus, 80 or more spots were resolved, of which 40 to 60 unambiguous telomeres could be tracked for extended periods within each total 200-second data collection timeframe (see C-E in Additional file 1).
However, diarrhea was reported much less frequently in 2005 than 2008 (16% and 21% respectively), despite data collection during similar timeframes for both survey years.
While this may have increased recall of responses to questionnaire items, in the interest of limiting measurement differences due to actual HRQoL changes, we chose to undertake data collection within this timeframe.
The aim of these meetings was to introduce the research objectives, target population, rationale and history of the questionnaire, give detailed discussions of each item in the questionnaire, and plan for instrument translation, adaptation, pre-testing and data collection within the allocated timeframe, which was scheduled to start in March of that year.
Case note data for NG tube patients was collected over timeframes which encapsulated data collection periods from all three intervention hospitals pre- and post-intervention implementation.
This leads to variations in the care with which informed consent is obtained, diligence in application of inclusion and exclusion criteria, rigor of collecting information on concomitant medications and use of over-the-counter treatments, attention to timeframes of data collection, thoroughness of adverse event reporting, and completeness of data collection and recording [ 37].
Timeframes for data collection (Table 1) were different between hospitals due to the time-point at which an organisation agreed to be involved in the project, and/or the rate at which patients were receiving an NG tube (e.g., in some hospitals there were considerably more patients receiving an NG tube per week than in others).
However, it may be possible that moisture generated has not fully condensed to recover the heat of vaporization given up, within the timeframe of data collection.
