Point Description Description Description

Broad Topic Area/Title The main topic of the study is the systematic review of the relationship between the nurse skill mix and the nursing sensitive patient outcomes within the acute care settings. It has been stipulated that nurses with high skill mix tend to ensure effective patient outcomes in the treatment process. The broad topic of the study is to determine the impacts of psychosocial interventions on the quality of life among the adult cancer patients. The main topic of the study is to examine the effects of nursing shortages on the patients care within the healthcare settings.

Identify Independent and Dependent Variables and Type of Data for the Variables Independent variable: Nursing sensitive patient outcomes (Categorical variable)(HLT 362V Week 2 Assignment: Population & Sampling Distribution Excel Worksheet)

Dependent variable: Nurse skill mix (categorical variable) Independent variable: psychosocial interventions (categorical variable)

Dependent variable: Quality of life (continuous variable)

Independent variable: Number of Nurses (continuous variable)

Dependent variable: Quality patient care (categorical variable)

Population of Interest for the Study The population of interest in the study include nurses and other healthcare professionals whose responsibilities are similar to the roles played by nurses. The population of interest in the study is the cancer patients. The process of the study is to measure the outcome among the adult cancer patients that have been given the psychosocial treatment. Only the patients above 18 years of age were considered in the study. The population of interest is the nurses and patients. The number of nurses and patients identified for the study were selected from different healthcare settings. The number of quality healthcare outcome was measured against the number of nurses to determine the effect of the treatment processes.(HLT 362V Week 2 Assignment: Population & Sampling Distribution Excel Worksheet)

Sample The sample size for the study was 63. In other words, 63 individuals were selected for the study; these included nurses in various healthcare settings. The sample size used in the study was 3120. These included cancer patients from various healthcare settings identified by the study participants. The sample size was 657. This involved physicians who were identified from various healthcare settings. The participants were also provided with the questionnaires so as to enhance data collection processes.(HLT 362V Week 2 Assignment: Population & Sampling Distribution Excel Worksheet)

Sampling Method Simple random sampling technique was used to gather information from the selected study participants. Their records were identified and biodata recorded appropriately. Simple random sampling technique is one of the most effective ways of collecting data from the study participants. Simple random sampling method was used to identify the study participants. Individuals were selected randomly from the population of the cancer patients. Health records were then selected after the consent was signed with both the patients and their family members. The selected participants were then monitored or examined over a period of time to identify the effect of the psychosocial treatment on the quality of life. Simple random sampling technique was used to identify the study participants from the identified healthcare settings. Some of the participant’s information including age and the level of experience were obtain from the database.
