Assessing patients’ vital signs (VS) is an important health care component, particularly among patients receiving acute care. VS are measurements of the body’s basic functions, indicating overall health. The main VS routinely monitored by health care providers are body temperature, pulse rate, respiration rate, blood pressure, and oxygen saturation (SpO₂) [1]. VS assessment allows objective investigation and monitoring of patient health. Patient safety is also a concern in health care, and studies report that VS assessment helps improve patient safety in medical units, reducing the risk of adverse events and providing better patient care [1-3]. Thus, regular VS assessment can be important to ensure efficient and potentially critical clinical follow-up and intervention for patients as necessary [4].

Despite the well-established benefits of VS assessments, global health care professional shortages have made VS screening often impractical in busy modern health care settings [5]. Adding VS assessments as they are conducted today to every consultation would be problematic given the pressures on staffing and clinical flow [6]. A survey of 25 general practitioners (GPs) conducted by Wavescope Ltd from February 2023 to January 2024 found that GPs take patients’ VS during 30% of consultations and that they could spend approximately 3 minutes taking VS in each consultation. Based on standard working hours, this indicates that full-time GPs in Ireland spend approximately 110 hours per year measuring patients’ VS.

VS measurements can also result in “white coat hypertension,” a phenomenon of elevated blood pressure due to patient stress in the presence of health care professionals [7]. However, studies consistently show that having blood pressure measured by nonphysician staff such as primary care assistants (PCAs) results in significantly lower readings and less “white coat effect” compared to measurements taken by a physician [8]. Research also indicates that VS assessments are often undervalued by clinicians and not recorded faithfully or frequently enough. For instance, a retrospective analysis by Hayes et al [9] of patients revealed that 98% of patients had substandard VS records.

The worst consequence of poor adherence to VS assessment procedures is a greater probability of medical problems deteriorating, potentially to a severe degree among patients with acute health problems [10]. Thus, this study aimed to address these issues by introducing a preclinic VS assessment (PCVSA) procedure in a busy primary health care setting. The study used a Welch Allyn Connex Vital Signs Monitor 6000 Series (MDI Ireland Ltd) [11]. Radio frequency identification (RFID) technology was used to transmit patients’ VS data to the GP via practice management software.

Each patient’s VS assessments were conducted by a PCA while they waited to see the GP. A PCA in Ireland works under the leadership of other health care professionals in primary care to assist and deliver delegated nursing tasks. While common in Irish primary care, PCAs are not part of every setting. PCAs require a Quality and Qualifications Ireland Level 5 qualification for entry to the profession. The patients’ VS data were produced in a report sent to the GP before they saw the patient, allowing them to maximize time spent on clinical decision-making. We hypothesized that the PCVSA would be feasible and acceptable from the perspectives of participating stakeholders, namely, the GP, support staff, and patients.

This study introduces a novel approach to VS assessment in primary care. The study introduces several new elements, including PCA/practice nurse–led PCVSAs, the application of RFID and time stamping technology to calculate time savings, and the automated sending of VS data via practice software before face-to-face consultations for clinical decision-making. To our knowledge, previous studies have not examined the benefits and drawbacks of conducting VS assessments before patients enter the doctor’s office or the seamless integration of these data into doctors’ electronic health records in a primary care setting.

We aimed to determine the feasibility and acceptability of implementing a PCVSA procedure in primary care. The feasibility was assessed using Bowen et al’s [12] feasibility framework (Figure 1). This framework helps researchers identify barriers and facilitators, guiding decisions on future studies/trials. Outcome measures included study engagement data, timings of each stage of patients’ GP visits, and self-reported questionnaire and qualitative interview responses from patients and staff regarding their views and experiences of the study and topic (Multimedia Appendices 1 and 2). These were developed by the research team and informed by the literature. The study is reported according to the iCHECK-DH (Guidelines and Checklist for the Reporting on Digital Health Implementations; Checklist 1) [13].

Each patient was given an RFID sticker attached to a card [14]. The PCA called each patient for a VS assessment in their office, and patients scanned their RFID card at a VS assessment station. The PCA measured patients’ VS using a VS measurement machine. Provisions were made for up to three VS assessments at 5, 10, and 15 minutes if results were abnormal. The PCA placed the RFID card on the RFID scanner to log the time of examination initiation and termination.

Patients returned to the waiting area, and their VS were transmitted to the GP via practice management software for review before the patient was admitted to the GP’s office. Once there, patients scanned their RFID card at the beginning and end of their visit. The GP and patients completed questionnaires regarding their consultation experiences. The GP also completed a doctor satisfaction questionnaire at the study’s end for overall impressions. Qualitative interviews were conducted with staff to investigate their experiences. Figure 2 shows the study procedure.

The RFID sticker used a featured custom RFID code [15]. This facilitated the collection of RFID data and the time when RFID stickers were presented to RFID readers [16]. As mentioned, the VS measurement machine used was a Welch Allyn Connex Vital Signs Monitor 6000 Series. The practice management software used was Socrates [17].

The study was conducted in a primary health care center in a Dublin City suburb in Ireland from 9 AM to 12:30 PM each day from July 8 to 10, 2024. Participants included practice staff and a target of 20 adult patients attending GP appointments. Research indicates that our target of 20 was satisfactory [18]. Inclusion and exclusion criteria are in Textbox 1.

Patients were recruited as they attended GP appointments. At check-in, patients were informed by the receptionist that a study was running to evaluate a PCVSA procedure. The patients were given a participant information leaflet (PIL) to read. The PCA and research team assisted patients, who could take home the PIL to think about participating and provide consent during their next visit if the study was still in progress.

Staff invited to participate were also given a PIL and could discuss the study with the research team.

The project was led by Wavescope Ltd in partnership with the School of Medicine, University College Dublin (UCD). Wavescope Ltd developed the PCVSA, and UCD led its evaluation. Project funding to Wavescope Ltd was provided by Enterprise Ireland via their Pre-Seed Start Fund [21], and the UCD team was supported by this fund and in-kind contributions from the Health Research Board, Ireland East Hospital Group, and UCD’s College of Health and Agricultural Sciences and School of Medicine. Wavescope Ltd owns the intellectual property of the study’s tracking code and the study design and layout.

Wavescope is developing a platform that performs VS assessments in waiting rooms using a reusable wearable device, sharing data with clinicians before patients enter the room. Such a system could improve compliance with World Health Organization timing guidelines, reduce white coat hypertension, standardize data collected, reduce time to conduct consultations, and improve patient satisfaction.

Ethics approval for the study was obtained from the UCD Human Research Ethics Committee (LS-24‐36-Broughan-Cullen). Patients and staff were given a consent form to review and sign before participating. All data were collected, stored, processed, and shared in accordance with the General Data Protection Regulation. A total of €2200 (€1=US $1.15 as of June 12, 2026) was given to support access to clinic facilities and staff time compensation.

The study was conducted in a primary care center in a Dublin City suburb. The sampling frame (patients scheduled for GP appointments) represents a small part of the patient population in this setting, with 36 patients scheduled (12 daily). Of these, 14 (39%) did not participate because of cancellations, language barriers, or ineligibility. Of the 22 remaining patients, 16 (73%) completed the study. Demographics are presented in Table 1. As per agreements with site management, 4 staff members (GP, PCA, receptionist, practice manager) were invited to participate, and all consented. The GP was male; the others were female.

The PCVSA could be a feasible and acceptable initiative in primary care. The findings suggest that PCVSAs have potential for saving time, enhancing patient engagement, and facilitating more productive and efficient consultations.

Previous research indicates that VS assessment can be important to ensure effective clinical evaluation, providing crucial health data for triage, prevention, and safety, particularly for patients who are vulnerable or in the hospital [22-26]. Our study highlights the importance of PCVSAs in a GP setting, with the findings emphasizing the perceived value among practice staff of PCVSAs in saving time and improving patient engagement and consultation quality.

The average time reported by the PCA for conducting PCVSAs (2.4 min) is notably shorter than the 3.75 minutes reported by a similar study [27]. However, that study was conducted in a hospital rather than primary care setting, and research mentions that meaningfully comparing VS assessment timings between studies is difficult because of variations in assessment methods [3]. It is important to note that the average GP visit time reported in this study (9 min and 21 s) only captures the GP’s patient-facing work and should not be confused with the complete consultation time. Previous research by Crosbie et al [28] and Pierse et al [29] calculated this to range from 14.1 minutes to 14 minutes and 36 seconds, and a survey of Irish GPs found the average consultation time in Irish GP practices was 13.7 minutes [30].

Ullah et al [5] reported on the increased workload associated with VS measurement in general practice, an important consideration. However, our study’s findings demonstrate that the use of PCVSAs, despite concerns about staff workload and language barriers during consenting, did not hinder the PCA from managing 16 patients. This led to a perceived reduction in time spent during GP visits and GP workload among participating staff, as well as improved patient experiences and satisfaction. Elliott et al [31] identified gaps in the assessment of VS, emphasizing the need for consistent and thorough measurement to ensure patient safety and effective surveillance in acute settings [31]. Our findings provide support for this position in primary care. The positive feedback from patients and staff underscored PCVSAs’ value in improving patient engagement, consultation efficiency, and overall satisfaction.

The PCVSAs could have several positive implications for practice. It might lead to improvements in care quality, identifying health problems, operational workflow and time management, patient/staff satisfaction, and patient/staff relationships and communication. A barrier to routinely conducting VS assessments is the extra time and workload assessments may bring [5]. A PCVSA that does not require direct staff involvement (eg, using validated wearable devices) may overcome this. From a research perspective, the main implication of our findings is the need for continued research examining PCVSA’s potential in primary care as well as other contexts. Larger-scale feasibility studies in diverse settings are advised to show proof of concept, and randomized controlled trials may have value in terms of comparing PCVSAs to usual care on key outcomes, perhaps GP visit timings, identification of health problems, or hospital admission frequency.

The sample was small and specific to adult patients and staff in one practice, thus limiting generalizability. Testing in larger and more diverse samples is required. GP visits were timed from when patients entered the GP’s office to when they left. Future studies should also include GP time for non–patient-facing duties such as essential administrative, management, and clinical support tasks.

The study demonstrated good levels of feasibility and acceptability with regard to using a PCA for PCVSAs in terms of saving time and improving patient engagement, perceived consultation efficiency, and satisfaction. However, it also highlighted feasibility and acceptability challenges that need addressing in the future. First, language barriers impacted recruitment, and future studies should take measures to address this. Second, GP visits were timed from entry to exit and excluded time spent performing non–patient-facing duties. The short time frame of this study did not allow for adaptation to address these issues. Furthermore, the study was piloted in a single practice whose staff were motivated to participate, and this may have biased their evaluation. The short duration of the study may have resulted in a limited impact on practice workload compared to a large-scale study. While these factors limit the findings’ generalizability, their findings still suggest that a PCVSA procedure would be both feasible and acceptable.
