Abstract
Objective:
The objective is to establish design strategies to help minimize nurse journeys and inform future decision-making. The impact of the ward layout was investigated through a case study ward in a multispecialty hospital in Tehran.
Background:
Nurse teams have the most direct contact with ward patients. Time spent on activities not part of care provision should be minimized. Literature suggests that a significant part of nurses’ time is spent moving between different places within wards, which emphasizes the importance of ward layout.
Methods:
The ethnographic method was adopted for observing nurses’ actions based on routes that form a significant share of nurses’ daily journeys. Data were collected from 42 nursing staff over 120 hr during different shifts. This provided empirical data on the frequency of each journey which revealed meaningful patterns. Approximately 1,300 room-to-room journeys were made. Conclusions were drawn about the criticality of each route.
Results:
There is a significant difference between the frequencies of different routes in the case study ward. The distances between origins and destinations of the most frequently used journeys must remain minimal. Awareness of less frequent routes allows for greater flexibility in ward design.
Conclusion:
Arrangement of ward spaces can minimize journey times. Healthcare planners and designers can explore the implications of chosen systems on walking distance and, consequently, the nursing staff productivity. For existing wards, rearrangement of space utilization can improve staff productivity. The recommendations can be applied wherever productivity is influenced by walking distances.
Keywords
Healthcare environmental interventions and their impact on patient health outcomes have been the focus of a significant body of research over the last decade (Laursen, Danielsen, & Rosenberg, 2014). Many previous studies cover maintenance, refurbishment, or relocation practices, where the health outcomes of patients are measured before and after each intervention. Some offer comparisons between healthcare environments and qualities which contribute to the health outcomes. A review of these studies demonstrates that healthcare environments can significantly impact the healing process and patients’ well-being (Huisman, Morales, Hoof, & van Korta, 2012). Such evidence suggests that, for example, interventions in healthcare built environments can contribute to a 9% reduction in the duration of patient stay in a hospital (Ulrich, 1984), a 22% reduction in patients’ feeling of pain (Lawson & Phiri, 2003), a decline of 67% in medication errors (Hendrich, Fay, & Sorrells, 2004), 17.3% reduction in patients’ fall accidents (Brandis, 1999), and 70% reduction in patient psychological distress (Lawson & Phiri, 2003) and may even result in total eradication of hospital-acquired infections (Oren, Haddad, Finkelstein, & Rowe, 2001).
There are many factors that contribute to the design of more efficient hospitals (Kazanasmaz, 2006). Supportive built environments with good internal layouts, accessibility, and circulation can create an overall inviting, calming, engaging, and more hygienic and productive healthcare environment for staff, patients, and their relatives.
Improving productivity in hospitals is a long-standing issue. Kuhn (2000) introduced Henry Ford, founder of Ford motor company, as one of the pioneers of transferring the concept of productivity from automotive industry into healthcare. When designing a hospital for his staff, Henry Ford stated “in a normal hospital, nurses are forced to make many unnecessary steps; hence they spend more time walking around than nursing the patients” (Kuhn, 2000, p. 1), which still seems to be a challenge today. A later study showed that nurses spend close to one third of their time walking in the unit between patient rooms, the nursing unit core, and the nurses station, which, in turn, resulted in fatigue (Joseph & Ulrich, 2007).
Much research has investigated the negative or positive impact of different environmental factors on nurses’ work processes and the importance of enhancing these processes (Applebaum, Fowler, Fiedler, Osinubi, & Robson, 2010; Chaudhury, Mahmood, & Valente, 2009; Hayhurst, Saylor, & Stuenkel, 2005).
One of the key physical factors of a nurse’s work environment is the ward configuration and special complexities (Sagha Zadeh, Shepley, & Waggener, 2012). Several studies support the significance of improving ward organization and design as well as optimizing the nurses’ movement to increase the quality of nurses’ time, the safe delivery of care and healthcare unit productivity (Hendrich, Chow, Skierczynski, & Lu, 2008; Heo, Choudhary, Bafna, Hendrich, & Chow, 2009), and substantial functional and financial efficiency (Sagha Zadeh et al., 2012). Many efforts have been made to improve the performance of medical staff by changing workspace layout. Some studies investigated the impact of the unit layout on the amount of time spent walking and demonstrated that saved walking time can be translated into more time spent on patient care activities and interaction with family members (e.g., Shepley, 2002; Shepley & Davies, 2003; Sturdavant, 1960; Trites, Galbraith, Sturdavant, & Leckwart 1970; Nazarian, Price, & Demian, 2011) as well as improving patient satisfaction (Robert Wood Johnson Foundation & Institute for Healthcare Improvement, 2006).
Method
Data were collected between May 26 and June 20, 2013. Forty-two members of staff, including head nurse, nurse, nurse assistant, and ward housekeeper, participated during three different working shifts.
Site and Settings
A general hospital ward in Iran was selected because of its availability, that is, a convenience sampling strategy. The case study ward accommodated 16 inpatients in four double-bed rooms and eight single-bed rooms with an approximate total floor area of 440 m2 (4,736.12 ft2). The ward usually housed patients requiring various internal surgery procedures such as orthopedic; urology; general surgeries with open, advanced, or laparoscopic methods; brain and neurosurgeries; spinal cord; plastic surgery; ear, nose, and throat surgeries; thorax surgery; and various cardiovascular procedures.
Rooms were arranged around an “L-shaped” corridor with the nurses station positioned at the bend in the corridor to maximize views to the whole ward. Most of the single-bed rooms had a floor area of 17.5 m2 (188.37 ft2; including en-suite sanitary facilities); double-bed rooms had a floor area of 25.5 m2 (274.48 ft2). The area of other spaces in the ward was measured as follows: the nurses station: 12 m2 (129.17 ft2); treatment room: 25 m2 (269.10 ft2); staff room (including toilet and shower): 24.5 m2 (263.72 ft2); staff changing room: 7 m2 (75.35 ft2); hoteling storage: 3 m2 (32.29 ft2); soiled room: 1.5 m2 (16.15 ft2); and cleaning utility: 0.8 m2 (8.61 ft2).
Participants
Patient care activities were performed by three types of staff members: head nurse, nurse, and nurse assistant. Housekeepers were also responsible for the physical maintenance and cleanliness of the ward. The nursing activities of different staff types were designed based on the following shift pattern (Table 1).
Number of Ward Staff per Shift.
There were no meaningful changes in the workload distribution between different days of the week, as confirmed by the staff in the interviews, due to the random nature of the health problems referred to this ward. The observed nursing staff had various duties as follows: Head nurse: Head nurse or in-charge nurse in the ward was responsible for the performance of all staff and the monitoring of nurses, nurse assistants, and housekeepers to ensure they met all their targets. She or he also ensured that all the patients’ needs were met, and hospital’s service level standards were observed by allocating resources (including nursing staff, medication, doctors, and equipment) where needed. In the absence of the head nurse, one of the most experienced nurses in the ward, previously trained to act as in-charge nurse, assumed the head nurse’s duties. Nurse: In the observed ward, the bulk of the care, especially medical and emotional care, received by the patients and their families was provided by the nurses. Furthermore, nurses played a major part in monitoring and recording patients’ well-being and complementing activities of the doctors in their absence. They were also prepared to deal with different types of emergency that could occur in a ward. As part of their daily routine, nurses also made frequent journeys to other parts of the hospital outside their own ward. These journeys were normally to escort patients to and from their destinations outside the ward. Nurse assistant: A significant part of patients’ physical care was performed by nurse assistants. These included all nonmedical matters that facilitate the healing process of the patients such as supporting personal hygiene and daily living needs. Also, transportation of the patients to and from other departments was one of the responsibilities of the nurse assistants. Ward housekeeper: Housekeepers were observed to be solely responsible for the upkeep of the facilities of the ward. The housekeepers’ duties included cleaning and sanitization of toilets and showers, patient room equipment, nurses station, medical equipment, corridors, escape routes, bins, cupboards, and lifts. Cleaning and preparation of the patient room and bed before the arrival of a new patient was also part of their job. Although data were collected for their housekeepers’ activities, these were subsequently excluded as they had no nursing responsibilities.
Data Collection
The first phase of data collection involved observing nursing staff activities to create realistic lists of duties and tasks performed by different types of nursing staff throughout each working shift. The lists were then validated by interviewing staff members to ensure their comprehensiveness. Of the 42 staff members who were observed, 9 were interviewed. These interviews lasted an average 30 min. A summary of these lists is presented in Table 2.
List of Daily Activities per Staff Type.
Based on the observations and arrangements made in the preparation phase, a strategy for data collection was developed. The aim of this strategy was to manually observe all types of staff members within a 24-hr cycle (divided in two 6-hr shifts and one 12-hr shift) and record their movements between different spaces in the ward by the researcher. This was judged to be sufficient for the observation of head nurse and nurse assistant’s activities that change little in their routine from day to day. For nurses, however, whose duties are much more dependent on the types of patients to whom they are attending, the routines and even the workload could meaningfully vary from day to day. For this reason, it was deemed prudent to observe each working shift of the nurses 3 times to eliminate the possibility of having skewed data on their activities. There were no noteworthy variations in journey data across the nursing staff types for the duration of observation was carried out for this study. The observation comprised 120 hr direct observation of: 72 hr of nurse activity; 24 hr of head nurse activity; and 24 hr of nurse assistant activity.
These were distributed over 2 weeks of observations in a pattern to cover all shifts equally. Every effort was made to ensure that observations covered as many different participants as possible (rather than observing the same nurse in different shifts). This was to eliminate the confounding effect of an individual’s personal working patterns.
As a result, data collection forms in Tables 3, 4, and 5 were designed and tested through a pilot study over a shift to ensure the logical flow and practicality of the data collection procedure.

This method enabled the researcher to gather four different variables of data on each journey within the ward: the origin of the journey; the destination; start time; and end time.
Figure 1 presents the simplified layout of the selected case study ward. This study was not concerned with the movements of the participants inside rooms, as the main concern of study was the overall layout of the ward and the design of the corridors rather than the rooms themselves. Therefore, the origin/destination points of corridor journeys (numbers in Figure 1) only indicate the point of access to each of the following: Point 1: Nurses station; Point 2: Treatment room; Point 3: Staff room; Point 4: Soiled room; Point 5: Used sheet bin; Point 6: Ward entrance; Point 7: Isolation-adaptable room; Points 8, 9, 10, 13, 17, 18, 19: Single-bed rooms; Point 11: Utility; Points 12, 14, 15, 16: Double-bed rooms; Point 20: Staff changing room; and Point 21: Storage.

Data Analysis
Field observations provided empirical data on the frequency of each journey taken by nursing staff within the ward. Meaningful patterns were revealed in the data collected from the case study using a set of data analyses. The following is a summary of these analyses. A total of approximately 1,300 room-to-room journeys were made by the nursing team in this ward in 24 hr. This is almost equal to one journey every 67 s. Several conclusions were made from the study of the journey frequency in different routes, including how critical the design of each route is, as summarized in Table 6.
Share in Daily Journey Frequency per Level.
Frequency Level 1
The most frequent nursing staff journey, the only journey taken more than 100 times during 24 hr (i.e., 8% all daily journeys), occurred between nurses station and treatment room (Points 1 and 2). This agrees with the observations made during this research regarding the importance of treatment room in hosting many nursing staff activities such as medicine preparation, in-house cleaning and sanitization, medicine and equipment stock check, and temporary storage of monitoring equipment and clean bedsheets. A good strategy in ward design is, therefore, to keep the nurses station and treatment room adjacent to one another. This strategy had been considered in the design of the case study ward by directly connecting the two spaces through a door, thus eliminating room-to-room walking.
Frequency Level 2
The next five most frequent journeys (i.e., those taken between 50 and 100 times a day) were also to or from the nurses station. The other ends of these journeys were Points: 3 (staff room); 7 (isolation-adaptable room); and 12, 15, and 16 (double-bed rooms). In the case study ward, apart from acting as a staff rest area, the staff room served an additional function as nonmedical administration office and ward meeting room. Subsequently, Routes 1–3 involved a substantial share of the team’s daily journeys due to their high frequencies. This suggests reducing the distance between the two spaces to a minimum, as in the case study. Visits from Point 1 (nurses station) to Point 7 (isolation-adaptable room) had one of the most frequent journeys. The reason was that the room was occupied by a patient in need of special and frequent treatment. However, the importance of isolating this room from busier parts of the ward had resulted in this room being one of the furthest rooms away from the nurses station. Visits to double-bed rooms were observed to be more frequent than those to single-bed rooms. Many tasks, especially those related to patients, needed to be repeated twice to serve both patients in these rooms. The only exception was the route to the double-bed room at Point 14; which, for most of the duration of the observations, was occupied by only one patient. It is reasonable to assume this route to be in Frequency Level 2 in normal circumstances. The routes with a Frequency Level 2 accommodated 29% of the daily journeys of the nursing staff in the ward.
Frequency Level 3
Most other journeys occurred on average more than once an hour and correspond to the routine tasks performed in patients’ rooms. This pattern reflects two categories of journey: those from the nurses station to single-bed rooms and those performed when taking “rounds” for activities such as doctor visit, medication, shift handover, linen change, and cleaning. The latter category does not seem to be greatly dependent on design type and the nursing team would take the physical order of the rooms for such tasks regardless of the overall arrangement of the spaces. Journeys from the nurses station to other parts of the hospital, such as pharmacy, offices, patient arrival, restaurant, and so on (i.e., Routes 1–6), are also in this range of frequency. In total, 19 routes have been categorized under this frequency level. About 41% of the daily journeys in the ward occurred in these 19 routes.
Frequency Level 4
All other routes fall in this category of the least critical routes. The 184 routes with this frequency level are used for about 22% of the daily journeys of the staff (about 0.1% per route) some of which were observed not to be used even once by the nursing staff during the observation period. These routes should be considered as the first choice if compromises are to be made in the design of the ward in favor of more critical routes and activities.
Design Recommendations for Minimizing Nurse Journey Times in Wards
The following sections summarize the emerging recommendations for minimizing nurse journey times in wards in relation to nurse station, treatment room, staff rooms, patient rooms, ward entrance, and a proximity matrix.
Nurse Stations
The evidence from this study established that, the nurses station was, by far, the most frequently visited space in this hospital ward. More than 50% of the nursing team’s daily journeys either start from or lead to this one space. It is, therefore, important to consider the positioning of nurses stations as the priority in the layout of a ward from the viewpoint of minimizing unnecessary walking by nursing staff.
Regardless of the overall layout of the ward, the nurses station needs to be in a central point of the ward providing easy access to patient rooms, isolation-adaptable room, treatment room, staff room, and ward entrance. However, compact designs offer an advantage over linear ones in keeping the walking distances to the end-of-the-row rooms to minimum. Inclusion of multiple smaller stations, instead of one central nurses station, is another strategy to allow easy access of the nurses to different rooms.
Treatment Rooms
More than 15% of all journeys to or from the nurses station (and 8% of all journeys in the ward) occur between the nurses station and treatment room. This is the most critical route in the ward from a walking distance perspective. Many nurse tasks (which start from the nurses station) need a stop in the treatment room, for example, to pick up medicines, wound dressing sets, and/or monitoring equipment from treatment room before attending patients. Most of the medical tools also need to be returned to this room for in-house cleaning. A significant part of documentation tasks was also performed here. Therefore, it is essential to keep the distance between this room and the nurses station to minimum or eliminate it (by providing direct access between two spaces without the need of going through a corridor) to insure prevention of any extra walking for the nursing staff.
Staff Rooms
The staff room had functions covering a broader range than the name suggests. Normally, ward staff visit the staff room only to take their breaks, have some quiet time, eat a sandwich, have a friendly chat, or have a drink. However, the staff room also played the role of the ward “office” hosting nonmedical administrative tasks of the staff, especially the head nurse. This, although not unprecedented (according to the expert interviews during the case study), is not a necessary part of staff room’s functions. Therefore, the bias of the data in overestimating the importance of the journeys to and from this space (with nearly 8% of all journeys in the ward) should be considered when these data are used to inform design guidelines. In general, if a staff room assumes extra functions as an administration office, it needs to be near of the nurses station and treatment room.
Patient Rooms
In addition to maximum accessibility and visibility from the nurses station, the arrangement of patient rooms needs to facilitate making rounds (performing tasks that need to be repeated in all patient rooms one after another). For this reason, it is recommended that patient rooms are kept next to each other in a way that all of them can be accessed in one round trip from the center of the ward (i.e., the nurses station). Placing patient rooms in separate wings in a ward or designing other spaces in between of a row of patient rooms, which adds unnecessary distance between the doors to two consecutive patient rooms, are design strategies that should be avoided if possible.
Ward Entrance
Apart from movements between different rooms inside a ward, all other daily corridor walks of the ward staff crossed the ward entrance. The journeys to or from this point in daily nursing staff’s journeys was slightly greater than 3% of the total. Journeys are to places outside the ward can form a large part of daily walking activities, as the distances are much greater than those of internal journeys. The greatest part of these journeys, however, occurs outside the ward and is, therefore, out of the scope of this study.
As far as this study is concerned, the most important space in relation to ward entrance is the nurses station. This means that the nurses station should be kept close to the ward entrance. Further to minimizing the walking distance between the two spaces, this strategy also insures that staff in the nurses station have constant visual control over the entrance. This is a quality that was recommended by the nurses and architects during expert interviews. However, the centrality of the nurses station (as stated earlier) is of a greater importance and should overrule its proximity to the entrance when both qualities cannot be satisfied in a design.
Proximity Matrix
To summarize the above guidelines, the suggested proximities of different spaces in a ward are presented in form of a matrix (Table 7). In this matrix, the strongest proximity need is coded as 1 (e.g., the nurses station to treatment room) and the least important ones as 5 (e.g., staff room to service and utility). The spectrum between these two extremes expresses how important it is for the designer to keep a pair of ward spaces close to each other. It is essential to note that this matrix only informs the minimization of the nursing team’s walking distances. Other factors that may affect the positioning of a ward’s different rooms and spaces should not to be overly compromised by this one factor. Also, the walking distances of other people in a ward, including nonnursing staff, patients, and visitors, should be considered in the final design of the ward. It should also be noted that the space names in this matrix reflect a set of specific functions as defined by the case study. These functions may have different definitions in other cases.

Discussion of Results
Data on journeys made by staff within a workplace should be an important part of determining the optimum proximity of different spaces within the workplace and selecting the most efficient design layout from several options. Methods such as the one presented in this article can be utilized for maximizing reliability and comprehensibility of such data without much reliance on the technical expertise of the observer or the sophistication of the equipment used.
Careful preparations are needed for data collection to ensure comprehensiveness of the data and to minimize data impairment. The example presented in this article explains such preparations as well as the processes of data collection, data cleansing, and data analyses.
Conclusions, Recommendations, and Limitations
Conclusion
This article provides an example of how the data gathered and analyzed from an existing working ward can inform decisions for future designs. This was done through the formulation of a set of design guidelines from the research findings. These guidelines include suggestions on the location of nurse stations, treatment rooms, staff rooms, patient rooms, ward entrance, and a proximity matrix of all spaces in a hospital ward. These suggestions are based on the dynamics and needs of the observed setting of the case study, and any potential generalization of these suggestions should be carried out with careful consideration of similarities and differences with the studied case.
Recommendations
The evidence from existing working patterns of the nursing staff and their room-to-room movements should form the basis of floor plan layouts in any future design (and redesign) projects.
In the design of new build hospitals, the planned staff working patterns are based on the routines of other clinical, nursing, and care teams in similar hospitals. Such assumptions may turn out not to be an exact representation of the actual working patterns of the staff after the occupation of the newly built hospital, therefore, not delivering the expectations of the designers, for example, as to the design’s enabling of effective staff journeys are. In contrast, nursing teams in existing hospitals that are planning to undergo a spatial reconfiguration or refurbishment have full knowledge of their current working patterns. It is essential that these patterns should be observed, analyzed, and validated with the staff before any decision on the new format of the hospital is made.
Hospital designs should accommodate potential future changes in working patterns.
Many factors such as new technologies, techniques, services, and policies may result in a shift in working patterns. Designing hospitals based on the current working patterns of the staff may have an inherent risk of a decline in the healthcare environment’s effectiveness and efficiency if working patterns change. Designs that provide a valid solution for current needs of a hospital should be sufficiently resilient and flexible to accommodate the future needs without imposing unnecessary cost and effort or disruption to service. They should allow spatial rearrangement of the hospital spaces when changes in working patterns occur.
Limitations
The data collected were from a specific context (a general hospital in Iran) and the findings might not be directly generalizable to other locations, types of hospitals, or healthcare systems.
Implications for Practice
The following describes how the research findings can inform the initial design of the internal layouts of hospital wards. The data collection and analysis methods discussed in this article can be used by decision makers, designers, and managers without the need for sophisticated devices and trained technicians. The article categorizes room-to-room journeys inside a hospital ward based on their frequency and ranks them according to their share in daily journeys within a ward. Design recommendations are proposed to inform the design of more efficient wards, in which nurses do not spend excessive time moving from room to room. These recommendations cover a range of guidelines for the overall layout of the ward and also the location of different rooms within the ward. These recommendations are summarized in a proximity matrix which represents useful adjacencies between spaces within a ward.
