Two patients were deemed unsuitable due to risk of general anaesthesia, and two further patients were declined entry by practitioners for other reasons outside of study protocols.
Thus, while the relatively simple biochemical protocols of metabolomics maintain a low barrier to entry, new practitioners of metabolomics experiments are forced to either purchase expensive software packages or craft their own data handling solutions from scratch.
Notably in Quebec, where the foundational social pediatric clinics have been established, primary care physicians are used rather than specialists as the point of entry; nurse practitioners are slowly being introduced into Quebec.
The internal validity of the surveillance programme will depend on the accuracy of classification of disease at the point of data entry by practitioners, together with a reliable source of denominator data.
These high expectations could be the result of three major factors: (1) the role of a new RN is not well defined; (2) entry level practitioners are now found in all areas of clinical practice; and, (3) the increased complexity and acuity of care provided.
The current educational model in dietetics is designed to prepare entry-level practitioners and academics who comprise less than 20% of the profession.
We then just have to reorient them to the nature of the assessment …" Assessors from an education background are seen as advantageous not just because of their skills but also because they have experience with entry-level practitioners.
The radium-therapy boom of the 1920s prompted the first attempts to discourage the entry of "inexpert" practitioners into radium therapy.
The detailed clinical profiling at study entry and general practitioners' access to the computer assisted treatment protocol may explain the large, clinically significant, reductions in blood pressure in both groups (mean change >13/7 mm Hg in the intervention group and >10/5 mm Hg in the control group).
While it is possible that this indicates decreasing performance over time, our analysis of practitioner entry and exit trends 2008 to 2010 elsewhere (Palmer et al. submitted) suggests that the practitioner workforce is growing faster than the general population in most countries, which would not support this hypothesis.
