Many areas of science require the scientist to leave their laboratory and go into the field for observation, data collection, experimentation, and other duties.
In the case of Luanda, where low level of schooling of CHWs was identified as a barrier to obtain data and maintain reliable records, we raise the point that years of schooling (as a prerequisite for CHW selection) might not be sufficient to determine a level of educational achievement necessary to fulfil the duties of satisfactory data collection.
Five individual face-to-face interviews were conducted with nurse-midwives who were on duty during the data collection period.
The survey was carried out among registered nurse anesthetists (RNAs), OR nurses, and LPNs working in an OR for at least 6 months and who were on duty during the data collection period.
Data collection and cleaning took place alongside routine duties between 2006 and 2011, primarily by MGH and assisted by JRF, MKC and FBW.
Data were collected by on-duty clinicians on an HTML data collection form (prospective e-form), populated using either a personal digital assistant (PDA) or personal computer (PC).
This number is based on the duty cycle for the data collection process and based on the susceptibility of nodes to failure.
At the baseline examination, a standardised data collection form was filled out by the duty physician (F.C.; E.M .. Baseline demographic variables, CAD risk factors and clinical signs were collected.
As described in [ 33], during the data collection period all healthcare workers (HCWs) on duty, patients, parents or tutors were invited to participate in the measurements.
The questionnaire for data collection was mailed to the GP on duty by the EMST and two telephone reminders were used to increase return rate.
