Table 5 shows the impact of the independent variables selected (type of patient, staffing ratio, severity and length of stay) in the IPR-AASTRE-B.
That is; studies based on specific pre-selected types of patients (patients undergoing elective esophageal resection, cardiac or gastric surgery, liver transplant or suffering from acute liver failure), studies of non-ICU populations, populations for which the proportion receiving MV for >24 hours was <50% and studies for which VAP-IP data were not available.
Type 1 diabetes was confirmed in 57 of 70 randomly selected type 1 patients (population-weighted sensitivity, 32%; positive predictive value, 81%).
We performed a retrospective descriptive study based on chart review of 96 randomly selected type 2 diabetic patients.
We selected type 2 diabetes patients with the help of the four community health workers (CHWs) who have been working in KG Halli for the past 3 years as part of the Urban Health Action Research Project.
By the same token, however, one could argue that a similar bias would exist had we conducted a Delphi process with patients only, not to mention the difficulty that would be entailed in selecting different "types" of patients to participate in such a process.
In order to investigate whether GPs select different types of patients for recording symptoms in text or by code, we analysed the subgroup of all cases with a record of prior symptoms of breathlessness or wheeze, both coded and recorded in text.
Physicians tend to select treatments for different types of patients and illness profiles, a practice that may lead to lack of comparability between the treatment groups at initiation.
The underlying heterogeneity of many of the studied cancers and the types of patients selected may have masked efficacy in certain subgroups – the specific types of patients that showed promise in Phase I/II studies.
Results are certainly influenced by different clinic settings; for example, the long waiting period in the Kampo/Chinese medicine (Kampo/CM) clinic may have selected a different type of patients than the Integrative clinic with its shorter waiting time.
