Nurses' Work Schedule Characteristics, Nurse Staffing, and Patient Mortality" (Trinkoff, et al. 2011 p 1). The authors argue that lower nursing staff level can lead to poor patients' outcome and poor care, however, higher nursing skills mix can assist in recording lower mortality rates. In overall, increase in a number of nursing staff is associated with improving patient outcome. The authors use the quantitative technique to collect data from 633 nurses working in different 71 acute non-federal hospitals in Illinois and North Carolina. The study also uses a generalized estimating equation to examine the hypothesis. The research examines whether the authors explicitly states the research questions or hypothesis.

Hypotheses or Research Questions

Analysis of the research reveals that the authors do not explicitly state the research questions, and the absence of the research questions is not justified because one of the main features of quality quantitative research is to state the research questions that authors attempt to answer. By stating the research questions, the readers will understand whether the authors have answered the research questions from the research findings. Moreover, stating the hypothesis is important in a quantitative research because it gives direction to a research. Thus, the hypothesis assists in the formulation of a research problem, which the authors attempt to solve.

While the authors state the hypothesis in the study, however, the hypothesis is not appropriately worded. The stated hypothesis in the study is as follows:

Hypothesis: "It was hypothesized that, in hospitals where nurses report more adverse work schedules, mortality rates will reflect poorer quality care". (Trinkoff, et al. 2011 p 2). Despite stating the hypothesis, the authors do not state the hypothesis in an appropriate format, which can make a reader missing the hypothesis. However, the authors state the study population that consists of 633 nurses working in non-federal hospitals. While variables are mentioned in the study and provide a clear specification of key variables, however, the authors do not explicitly mention the key variables, and only experienced readers can identify the variables in the study. Despite the shortcomings identified in the method used in stating the hypothesis, the hypothesis has been consistency with the conceptual framework and literature review.

The authors review the literature showing that patients' mortality is correlated with lower staffing levels, and increase in nurse staff assists in improving patient's outcomes because extended work schedules can cause performances deficits and fatigue among nursing professionals. The authors use the balance theory as the conceptual framework to demonstrate how job performances affect human imbalances with the aspect of excessive demand for the job.

Literature Review

Analysis of the literature shows that the literature used are not mainly the primary sources. Rather, the authors use the combination of primary and secondary sources to complete the review. However, the review provides a synthesis of evidence on the research problem by explaining how lower nursing staffing contributes to the poorer health outcome. The literature also identified the balance theory for the conceptual framework revealing how work performances and excessive work demand affect patient's outcomes Moreover, the literature provides a leeway for further study because "the authors do not examine other aspects of the nurses' work environment, which can affect nursing care practices, such as work schedule characteristics related to patient outcomes". (Trinkoff, et al. 2011 p 2).

Conceptual/Theoretical Framework

The theoretical framework identified is the balanced theory and is appropriate because it provides the relationships between factors influencing nurses' work performances within the work environments and patient's outcomes.

Method

The absence of human rights protection is one of the shortcomings of the study. While the authors collect data from human subjects, the study does not provide the method employed in protecting the participant's private information. Safeguarding the rights of participants is one of the core aspects of quantitative research because it is mandatory for a researcher to protect the private information of the participants from the third party. Moreover, the study has not been reviewed by the ethics review board or IRB (institutional review board). In the United States, the IRB is an independent ethical committee designated to monitor, review and approve behavioral and biomedical research. The purpose of the IRB is to protect the welfare and rights of human participants. Since the IRB does not review the study before it is published, it is deemed that study is not designed to maximize.....
