1CRITICAL REVIEW IN STATISTICAL CONTEXT
The paper focuses on the quality of sleep exhibited by surgical patients in the setting
of health institutions. A descriptive study has been conducted among 411 patients and a
manually prepared questionnaire has been used aiming at the factors affecting the personal
information regarding the sleep pattern of patients. Regarding the methodology used in the
paper, voluntary participation of patients has been studied. Overall, 411 patients have
participated in the survey and submitted the data though questionnaire developed on the
Pittsburgh sleep quality index. The method of the survey chosen has been appropriate as the
selection of patients has been done in a clear way excluding the incomplete forms. Moreover,
the data collection methods have been genuine with the help of software based statistical
index. In addition to these, the author has also kept in mind the ethical considerations for the
study justifying the approval of the survey undertaken. All rules and guidelines have been
followed according to the declaration made by Helsinki. Added advantages of the
methodologies used in the paper has been the proper use of statistical tools for bio statistical
analysis like the Whitney U test, ANOVA or analysis of variance and Students T test. The
high significance from the T test is a clear indication of the acceptance of the hypothesis
(Yilmaz, Sayin and Gurler, 2019).
Similar studies has been conducted by Alexander et al (2014), among 9611 patients
who have undergone cataract surgery through the Pittsburgh Sleep Quality Index (PSQI). The
studies have been in alignment with aforementioned survey stating that patients undergoing
surgery or post-operative treatment have often shown improper sleep patterns. Another study
conducted by Manian and Manian (2015) among the patients who are adult and hospitalized
suffering from infection, state that the results have been contradictory to the findings of the
author as self-reported unsound sleep have been common and frequent among hospitalized
patients often undergoing infection related diagnosis. Research ethics implications has been
considered here as the proper consent of the patients has been taken during the study.

2CRITICAL REVIEW IN STATISTICAL CONTEXT
Moreover the whole study has been conducted considering the various ethical principles of
the patients including the principle of beneficence, principle of maleficence and related
principles.
There are some subtle flaws in the quantitative analysis of the study as the variety in
the variables taken for comparison is lacking in the assessment. Moreover, the type of
questions and the reason behind the proper choice of questions behind implementation of the
questionnaire is vague and not incorporated by the author. The research ethics during the
study conducted has been considered according to the findings of Patten and Newhart (2015).
Correlation and regression analysis of the variables used in the study have not been made.
Thus, further analysis could have been done considering the intricate statistical mechanisms
for the survey. According to Cohen, West and Aiken (2014), relationships between various
variables in a survey and quantitative analysis leads to a strong prediction and conclusion
about a given statement or hypothesis. Thus, estimation of the primary issue is much easier
with the use of statically tools and variables like correlation. The authors have also
considered the ethics of the patients in their studies following the ethical principles.
Thus from the above paragraphs, it can be understood that although the author have
used a clear methodology for analyzing the sleep deprivation of patients in hospitals, various
relations between the variables considered are missing. Thus, critically analyzing and
intricately reviewing the paper, the overall quality of the presentation has been good
pertaining to the information and the aim indicated in the study.
