Research Article Critique
The title of the research article I chose to critique is from the Journal of the American Geriatrics Society. “Hypertension, orthostatic-hypotension, and the risk of falls in a community-dwelling elderly population: The maintenance of balance, independent living, intellect, and zest in the elderly Boston study”; this title fits well with the content presented in the research article. The independent variables are clearly defined as well as the dependent variables for the research being conducted. The content of the abstract is a very good overview of the content and it is consistent with the content. The abstract summarizes the objective, design, setting, participants, measurements, and results. Problem/Purpose

The problem being investigated is the risk of falls in the elderly population related to the effects of controlled and uncontrolled hypertension and orthostatic hypotension. The authors do identify the significance of the problem as falls for being the leading cause of disability for the elder generations. Adequate background information is not provided to support the problem because the subject at hand “has not been investigated previously” (Gangavati, et al., 2011, p. 383). Explanation of the purpose of this study being conducted is provided by the authors. Literature Review

The previous research articles and their outcomes are briefly described with different amounts of time from 1-3 minutes after individual is standing before a decrease in blood pressure of 10-20mmHg would occur and be related to a fall. The purpose “was to assess the association between hypertension, OH using multiple definitions, and their combination and the risk of recurrent falls in a community-dwelling elderly population” (Gangavati, et al., 2011, p. 384). The list of twenty eight references is used is this article. There are eight references dated up to ten years old, four references dated five years old or less, and sixteen references that are more than ten years old with one of them being twenty-three years old. The authors do very briefly summarize their review of the literature as to what is known and not known to the study. They do explain a need for further study from previous research with a lack of knowledge in definitions of orthostatic hypertension presented. Framework/Theoretical Perspective

The study is based upon a specific situation theory regarding the relationship between falls and changes in blood pressure of the elderly population older than seventy. The authors connect their theory to the study by demonstrating a connection between a change in systolic orthostatic hypotension and standing for one minute. This change in systolic orthostatic hypotension would prove to be increasing falls for the elder population with uncontrolled hypertension. Research Question(s) OR Hypotheses

The hypothesis was that the risk of falls would be highest in people with uncontrolled hypertension and in those with orthostatic hypotension. The questions at hand of the research were to assess the association between hypertension, orthostatic hypotension using different definitions, and to assess their combination and the risk of falls in a community-dwelling elderly population. Variables

The independent variables were the total number of individuals that were seventy years old or older living within a 5-mile radius of the study. These individuals would present with no hypertension, controlled hypertension, uncontrolled hypertension, and systolic orthostatic hypotension. The dependent variables are the blood pressure measurements, number of falls reported, and the amount of time standing from one to three minutes. The blood pressure measurements were taken at two different times at two minutes apart after five minutes of rest and an average of the two would be used in...
