HLT 362V Topic 5 Discovering Relationships and Building Models

In the current health practice, providers rely heavily on data to make appropriate practice changes. Most changes focus on improving health and ensuring that patients and populations live healthily. Epidemiological data is among the widely used data sources in health care settings. It provides information on the distribution and determinants of health-related events and conditions in specified populations (Fontaine, 2018). Through epidemiological data, health care providers can adequately understand the causes, patterns, and other particulars of diseases and other health-related events. The purpose of this paper is to describe how epidemiological data influences practice changes, examples, and the necessary data for guiding practice change.

How Epidemiological Data Influences Changes in Health Practices

Health practices in health care organizations are designed to address specified populations’ health needs. For instance, an area where riots and accidents are common compels health care organizations to design special units and programs to respond to related emergencies. In places where people consume a lot of fast foods, health care organizations experience increased visits of children and adults with lifestyle diseases like obesity and diabetes (Singh et al., 2021). In response, facilities design programs such as health education and community visits to reduce such infections.

In field epidemiology, health care professionals collect data from investigations and vital statistics. Such data provides insight regarding health events like diseases, injuries, and environmental hazards count rates and patterns in terms of place, people, and time (Fontaine, 2018). Interpreting patterns and comparing them to the desired situations inform health care professionals about possible changes in the type and numbers of patients expected in hospitals and other facilities. The potential increase in patients triggers preparations such as increasing staff, adopting appropriate technologies, and reorganizing how health care teams function.

Examples of Practice Changes

Since the outbreak of the COVID-19 pandemic, health care professionals and researchers have explored many features of the pandemic, including transmission, distribution in populations, death rates, and prevention measures. One of the common findings was the need for minimal physical contact and travel, leading to the adoption of telehealth to facilitate remote patient monitoring and support (Monaghesh & Hajizadeh, 2020). The pandemic also fueled an unexpected increase in patients in the emergency departments forcing health care facilities to employ temporary staff and assign nurses new roles. Kim and Kim (2021) further observed that health practitioners required adequate provision with protective personal equipment (PPEs) and basic education to reduce transmission and help patients readily and more professionally. The rise in patients and uncertainty about when the pandemic will end increased anxiety, worry, and burnout among nurses. Most organizations responded through psychiatric support, command centers to improve communication, and opportunities for self-care (Rose et al., 2021). The changes have been instrumental in supporting health and improving mental and physical preparedness to cope with the pandemic.

Necessary Data for Practice Changes

Descriptive data is the most appropriate for practice change. It involves organizing, inspecting, and interpreting data to understand

current and historical patterns. Through descriptive data, health care providers can accurately dissect a public health concern like the COVID-19 pandemic into its component parts. Other uses include identifying at-risk populations, measuring the progress of control measures and their effectiveness, and generating testable hypotheses (Fontaine, 2018). The data helps health care providers to prepare effectively and make appropriate, data-driven interventions.


Epidemiology involves studying patterns, causes, risk factors, and other crucial elements of health-related events. The data generated guides health care professionals in implementing evidence-based control measures to protect populations from adverse effects. The study and management of the COVID-19 pandemic exemplify the professional application of epidemiological data to protect the public’s health and safety. Control measures dominating the pandemic’s management include telehealth, using protective equipment, and mental health support for nurses and patients.

Good one, Loreta.

In statistics, a sampling method is systematic if it involves selecting individuals or items for a sample such a way that every nth item is selected.

Systematic random sampling has various types but the most basic one is the simple systematic sampling. You just need to select from a random starting point but with a fixed periodic sampling interval.

How systematic samples are used: select a population and determine the size, divide the population into subgroups or strata of approximately equal size., decide your sample size and sampling interval, record data with survey software, analyze your data using real time analysis, form conclusions based on that analysis.

Great post, it is informative. Cardiovascular disease such as stroke is one of the main causes of acquired disability in most developed countries and considerably affects the life course of the victims. Depending on the affected brain area, stroke can leave long-term impairments of motor, sensory, and/or cognitive functions, but is also associated with social changes. Stroke can affect the relationships with children and the partners including the sexual sphere as well as deteriorate family dynamics and decrease participation in social activities (Bucki et al., 2019). Since most of the survivors return home, their family caregivers, mainly their partners, also experience these social repercussions of stroke. Expected to provide complex care at home in addition to having new responsibilities. After a stroke event, the quality of the relationship plays a key role in the respective well-being of the patient and the family caregiver. Some of the characteristics that remain in the patient after the stroke are trouble in speaking, paresis, and paralysis of one of all limbs that cause the inability to walk and feed me. So, family members have an extra burden taking care of the victim.
