I will choose observational retrospective cohort design for my study. My research question was to identify the association between socioeconomic, biopsychosocial, environmental and genetic factors, and the development of childhood asthma. To establish the effect of allergen (cockroaches, dust), poverty, poor air ventilation in a house, racial factors and air pollution on developing children asthma, a cohort have to have a exposure and the cohort need to followed over time. Cohort studies are used to study the incidence, causes, natural history of a disease and prognosis.1 Because they measure events in the chronological order, they can be used to distinguish between cause and effect.1 This type of study is the best method for determining the incidence and natural history of a disease or condition.1 One of the advantages of doing retrospective cohort study is that the data already collected for some other research study or purposes. The cohort is “followed up” retrospectively.1 The study period may be many years but the time to complete the study is only as long as …show more content…
Retrospective cohort studies are much cheaper as the data have already been collected.1 This type of study is the lack of bias because the outcome of current interest was not the original reason for the data to be collected.1 However, because the cohort was originally constructed for another purpose, it is unlikely that all the relevant information will have been rigorously collected. Retrospective cohorts studies have other disadvantages that people with the outcome of interest are more likely to remember certain antecedents or minimize or exaggerate what they now consider being as risk factors (recall bias).1 Sample or population selection and loss to follow-up is a major potential cause of bias.1 Any loss to follow-up can significantly affect the validity of the

1. Describe the study design (is it correlational, experimental, survey research, etc.). The study is Level 3, experimental. The participants are within subject design experiences because since the subjects were divided into two groups by gender.
In order to be able to compare test data between the principal corp program and the cohort program, I first had to eliminate any students who did not have a full set of test data. I deleted entire rows of students, even if the student was only missing one cell worth of data. I then moved all the data up within the spread sheet in order to not leave any gaps between the data. I then copied the total score data for the principal corp students and pasted it onto another Excel spread sheet file. I did the same for the cohort students’ total score data.
Will you be using a between-subjects or within-subjects design? If you have more than one IV, you need to answer this question separately for each IV. I will be using within subjects design. The participants will be given the same treatment during the experiment.
investigating the difference in results of using two different types of plant food Ans: identification of Relationship because trying to identify difference between two types of food. h. calculating the mean score on a final exam for a class of 100 students Ans: data reduction because trying to reduce everything and shows meaningful part. i. studying whether exposure to a certain type of chemical results in more frequent cancer diagnoses Ans: Inference because it tries to conclude how certain types of chemical results in more frequent cancer diagnoses. 3. Tell which type of sampling is used (random, cluster, systematic, convenience, and stratified and give clear reasons to support your answer.
It can also reduce substantial error and bias in a study design when the data is attempting to determine culturally different groups (Kaneshiro et. al, 2011). Furthermore, much of public health research is based on aggregated data. Therefore, it is easier to compare research to previous studies to determine if there has been an improvement in the population or assess the effectiveness of current intervention programs. In addition, aggregated data has been able to develop the best practices for asking questions to minority groups.
It was a privilege to work with Laura on a team rehabilitating a severely impaired brainstem CVA patient. She uses evidence based practice to modify treatment approaches to promote positive outcomes for both her patients physical needs as well as cognitive-communicative needs. A perfect example of this was scheduling her PT session prior to an SLP comm/cog session with increasing cardiovascular effort to promote improved cognitive
We projected that up to 10 interviews will be conducted and any necessary follow-up interviews will be conducted during the time frame of the study. In addition, follow-up interviews will be conducted with during the time of the study to allow time for data collection. All interviews will be tape-recorded and, based on four pilot interviews already conducted, are expected to vary in length from 15 minutes to 45 minutes. The interviews will be informal and open-ended, and carried out in a conversational style.
The literature review gives justified information for the need of conducting the research. Apart from the introduction, there is no other information concerning the research title that could offer detailed information (Chaliha et a., 2001). Despite giving the justified information in the introduction section the paper should have had the literature review section, thus it did not follow the due steps and format of a research paper. The methodology part follows after the introduction and it discloses the methods used, the design, the people included in the study and how the data was sampled and examined. However, the reasons for choosing the design in the research were not
This paper will illustrate how Hennepin County (HC) utilize monitor and maintain EHR records for the following business lines hospital, outpatient clinics, health, social and human service. Data sharing of EHR has allowed the organization to successfully provide care coordination for the population we serve. As healthcare evolves and service delivery continues to influence healthcare, it is essential that each business lines work together and collaborate to effectively access EHR within the Epic system. EHR systems, data bases, web portals are critical for a healthcare provider remain compliant with federal regulations. I am an HC employee, and my organization is unique, because we own and operate Hennepin County Medical Center (HCMC) and

Abstract: Randomized Controlled Trial study on advanced delivery mechanism simulator with Parallel Group Design was used with 38 randomly selected B.Sc nursing students of Bombay Hospital College of Nursing, Indore. The outcome of interest was pragmatic, and superiority trial was done. Out of 40 eligible participants, 38 participants were enrolled, and 2weeks were taken for pre test assessment. Allocation Concealment was done by the assessor, 38 participants were randomly divided into experimental and control group, also it was a single blind trial. The total study period was decided for 4 weeks.
