Summary
Developing a smartphone app for nurses requires early end-user involvement to address workflow variations and balance data security with usability. This iterative design process ensures a tailored tool for bedside clinical information access and documentation.
Area of Science:
- Nursing Informatics
- Software Engineering in Healthcare
- Human-Computer Interaction
Background:
- Nurses increasingly use computers, necessitating efficient bedside tools for clinical information access and documentation.
- Designing healthcare applications presents challenges due to the complex nature of patient care processes.
Purpose of the Study:
- To present the design, development, and testing of a smartphone application tailored for nurses.
- To utilize an adapted software development lifecycle model accommodating healthcare setting complexities.
Main Methods:
- An iterative development process guided by a modified software development lifecycle model.
- Three stages of formative evaluation with increasing ecological validity: requirements identification, usability testing, and on-site evaluations.
- Involvement of 11 end-users for initial functionality selection and iterative feedback.
Main Results:
- Early usability and on-site evaluations identified design issues and assessed tool adequacy and caregiver acceptance.
- The study confirmed the importance of end-user involvement to manage diverse nursing workflows.
- A balance between robust security for patient data and efficient, usable access was achieved.
Conclusions:
- End-user engagement throughout the development process is crucial for creating effective nursing tools.
- Successful app development requires collaboration between clinicians, IT security officers, and developers.
- Tailored solutions addressing the heterogeneity of nursing workflows enhance efficiency and usability.

72.2K
Plants have a life cycle split between two multicellular stages: a haploid stage—with cells containing one set of chromosomes—and a diploid stage—with cells containing two sets of chromosomes. The haploid stage is the gamete-producing gametophyte, and the diploid stage is the spore-producing sporophyte.

01:10Retrovirus Life Cycles
49.5K
Retroviruses have a single-stranded RNA genome that undergoes a special form of replication. Once the retrovirus has entered the host cell, an enzyme called reverse transcriptase synthesizes double-stranded DNA from the retroviral RNA genome. This DNA copy of the genome is then integrated into the host’s genome inside the nucleus via an enzyme called integrase. Consequently, the retroviral genome is transcribed into RNA whenever the host’s genome is transcribed, allowing the...

A nursing care plan can present in two forms: informal and formal. Informal is a care plan for the individual use of the nurse and goals they wish to accomplish during their shift. Informal care plans are not included in the patient chart. A formal nursing care plan is a written or computerized guide that organizes patient care. It is further subdivided into two: standardized and individualized care plans. Standardized care plans are pre-populated care plans for specific patient populations,...

The planning phase of the nursing process helps nurses set priorities, outline patient-centered goals and expected outcomes, and tailor nursing interventions to align with the aligned care plan. Through the planning phase, the nurse applies critical thinking skills to align and develop interventions according to the patient's needs. It provides continuity of care allowing patients to receive the maximum benefit from treatment. It serves as a pilot plan for allocating individual staff to a...

Biology is a natural science that studies life and living organisms, including their structure, function, development, interactions, evolution, distribution, and taxonomy. The field's scope is extensive and divided into several specialized disciplines, such as anatomy, physiology, ethology, genetics, and many more. All living things share a few key traits, including cellular organization, heritable genetic material and the ability to adapt/evolve, metabolism to regulate energy needs, the...
