Advantages of data visualizations for decision-makers

Data visualization holds significant advantages for healthcare professionals in enhancing their decision-making processes. There are many subjects where visualization can be helpful, giving healthcare workers valuable and practical insights.

Patient Satisfaction

First, we will discuss patient satisfaction, including considerations such as the level of happiness with the healthcare provider, the effectiveness of communication, and perceptions of the healthcare professional's competence in performing their duties.

Healthcare providers rely on understanding patient satisfaction for insights into improving care, tailoring services, and ensuring a positive patient experience. High satisfaction levels help in better treatment adherence, improved outcomes, and patient loyalty. Visualizing this data allows for a fast identification of areas for improvement.

Diverging bar charts are ideal for visualizing patient satisfaction levels, particularly when using Likert scale questionnaires. In these charts, negative responses are displayed on the left side of the axis, positive responses on the right, and possible neutral responses can be positioned in the middle or presented in a separate chart alongside the diverging bar chart. This format effectively captures and communicates the spectrum of patient feedback.

Flow of patients

By visualizing the flow of patients a lot of useful information can be extracted. You can explore the number of patients coming in and out, the length of the stay, the flow of patients within the hospital to different departments or the flow of patients from primary care to specialty services. 

Alluvial diagrams are commonly used to visualize flows, effectively illustrating the movement of patients into the hospital and their progression through various departments or specialty services. In this graph, each node corresponds to a different department, and the width of the lines denotes the number of patients.

However, for showcasing the length of stay, a more suitable option would be a
box plot or dot plot
. With these types of graphs, the distribution of the length-of-stay data of patients can be visualized effectively.

Occupied beds

Visualizing the correlation between the number of patients and occupied beds is important in making informed decisions to enhance healthcare efficiency. This visualization helps identify potential issues quickly.

A suitable chart for visualizing the occupancy rate is for example the bullet chart. This chart allows for the representation of the number of patients through a bar, the official bed capacity with a target line, and the ranges could be indicated by distinct colors. For instance, one color could signify when the number of patients exceeds the bed capacity, another indicating critical levels, and a third indicating that there are ample available beds. Be careful here that using the traffic light colors in this case is not recommended, since it is not color-blind friendly.

Staff - patient ratio

Visualizing the interplay between staff availability and patient numbers is crucial for informed decision-making in healthcare. This dynamic approach can help in identifying staffing patterns, peak hours, and potential shortages across departments. This can support aligning resources with patient demand. The visual representation offers an intuitive overview, enabling proactive adjustments for optimal resource allocation in the rapid healthcare environment.

A suitable chart for visualizing the relationship between available staff and patient numbers is the bullet chart, similar to the one used for occupied beds. This chart enables the representation of the ideal staff-to-patient ratio with a target line, while the actual ratio is depicted by the length of the bar. Ranges within the chart provide indications of whether the ratio is too low or too high. Multiple bullet charts can be utilized for day and night shifts as well as different departments, offering a comprehensive overview of staffing.

Identifying health disparities

Visuals enable us to discern if certain groups of people experience higher rates of illness compared to others. This is significant because it highlights disparities in health outcomes across various communities. For instance, if a chart indicates a significantly elevated incidence of a particular disease within one group compared to others, it brings attention to this disparity and encourages efforts to address the root causes, such as unequal access to healthcare or socioeconomic inequalities.

In this scenario, charts can effectively illustrate the distribution of diseases among various demographic groups. For instance, box plots or dot plots are suitable for showcasing this distribution. Additionally, a bar chart can present the incidence rates of a specific disease across different demographic groups.

Future strategies

Visualizations can be used to create predictive models for disease outbreaks, resource allocation, and healthcare needs. By analyzing historical data trends and patterns, public health officials can make more informed decisions about future strategies and interventions.

Line charts are ideal for illustrating historical trends and can also serve to depict future predictions. However, it's important to ensure clarity in distinguishing between actual data and predicted data within the chart. One approach is to differentiate them using a continuous line for actual data and a dotted line for predicted data.

Behavioral changes

Visualizations can engage the public in health promotion efforts by making data more accessible and relatable. By visualizing the impact of lifestyle choices on health outcomes, individuals may be more motivated to adopt healthier behaviors and prevent disease.

Charts and graphs designed for this purpose should be captivating and enjoyable to capture attention effectively. Behavioral changes are often depicted using engaging infographics. Options for graph types include pictorial charts, icon charts, or icon arrays. Additionally, easily understandable charts such as pie charts and bar charts are suitable for these cases.
