Nurs 6052 Week 6 Assignment: Research Critique
This critique will present the information from two different selected research articles. The discussion will be based on a critical appraisal of the two research articles that have been selected, “Effectiveness of an aspiration risk-reduction protocol” and “Impact of a nurse-driven mobility protocol on functional decline in hospitalized older adults”. Nurs 6052 Week 6 Assignment: Research Critique.
The authors of the research, Effectiveness of an aspiration risk-reduction protocol, have discussed aspiration as the most critical problem for the patients mechanically ventilated and receiving the tube feeding. This research work is an effort to develop methods to reduce the aspiration risk among the patients, who are critically ill, and receiving tube feedings, or mechanically ventilated patients. The effectiveness of a three-pronged intervention was evaluated during the research.

The other article “Impact of a nurse-driven mobility protocol on functional decline in hospitalized older adults”, determined the impact of a nurse-driven mobility protocol on functional decline. This research work is based on the non-equivalent control group design which provides mobility protocol as the independent variable, and length of stay as the dependent variable. The research was based on a qualitative study, the improved functional status and length of stay was recorded in older patients participating mobility protocol. The research made emphasis on the ambulation in hospitalized older patients.
Discussion
It is very necessary to evaluate the effectiveness of aspiration risk-reduction protocol among the patients with respect to gastric content, which are mechanically ventilated and receiving the tube feeding. There is no doubt that patient receiving tube feeding is at high risk of life threatening pneumonia.
The most serious tube feeding complication is considerd as Aspiration. Aspiration may result in respiratory failure and the patients who receive tube feeding during their hospitalization are at a particular high risk. Nurs 6052 Week 6 Assignment: Research Critique.

Validity in research refers to the extent researchers can be confident that the cause and effect they identify in their research are in fact causal relationships. If there is low validity in a study, it usually means that the research design is flawed and the results will be of little or no value.Nurs 6052 Week 6 Assignment. Four different aspects of validity should be considered when reviewing a research design: statistical conclusion validity, internal validity, construct validity, and external validity. In this Discussion, you consider the importance of each of these aspects in judging the validity of quantitative research.
To prepare:
Read the method section of one of the following quasi-experimental studies (also located in this week’s Learning Resources). Identify at least one potential concern that could be raised about the study’s internal validity. Metheny, N. A., Davis-Jackson, J., & Stewart, B. J. (2010). The effectiveness of an aspiration risk-reduction protocol. Nursing Research, 59(1), 18–25. Padula, C. A., Hughes, C., & Baumhover, L. (2009).

Consider strategies that could be used to strengthen the study’s internal validity and how this would impact the three other types of validity. Think about the consequences of an advanced practice nurse neglecting to consider the validity of a research study when reviewing the research for potential use in developing an evidence-based practice. Nurs 6052 Week 6 Assignment: Research Critique.
Post the title of the study that you selected and your analysis of the potential concerns that could be raised about the study’s internal validity. Propose recommendations to strengthen the internal validity and assess the effect your changes could have with regard to the other three types of validity. Discuss the dangers of failing to consider the validity of a research study.

Aspiration of gastric contents is a serious problem in critically ill, mechanically ventilated patients receiving tube feedings. Nurs 6052 Week 6 Assignment: Research Critique. The purpose of this study was to evaluate the effectiveness of a three-pronged intervention to reduce aspiration risk in a group of critically ill, mechanically ventilated patients receiving tube feedings. A two-group quasi-experimental design was used to compare outcomes of a usual care group (December 2002-September 2004) with those of an Aspiration Risk-Reduction Protocol (ARRP) group (January 2007-April 2008). The incidence of aspiration and pneumonia was compared between the usual care group (n = 329) and the ARRP group (n = 145). The ARRP had three components: maintaining head-of-bed elevation at 30 degrees or higher, unless contraindicated; inserting feeding tubes into distal small bowel, when indicated; and using an algorithmic approach for high gastric residual volumes. Two of the three ARRP components were implemented successfully. Almost 90% of the ARRP group had mean head-of-bed elevations of 30 degrees or higher as compared to 38% in the usual care group. Almost three fourths of the ARRP group had feeding tubes placed in the small bowel as compared with less than 50% in the usual care group. Only three patients met the criteria for the high gastric residual volume algorithm. Aspiration was much lower in the ARRP group than that in the usual care group (39% vs. 88%, respectively). Similarly, pneumonia was much lower in the ARRP group than that in the usual care group (19% vs. 48%, respectively). Findings from this study suggest that a combination of a head-of-bed position elevated to at least 30 degrees and use of a small-bowel feeding site can reduce the incidence of aspiration and aspiration-related pneumonia dramatically in critically ill, tube-fed patients.
