As resident-physician work hours have decreased, and patient complexity1 and hospital documentation2 have concurrently increased, concerns have mounted about the time residents have available for education and face-to-face patient care. Single-center internal medicine studies have found that 12% of trainee time is spent with patients vs 40% in front of the computer.3,4 To our knowledge, no multicenter studies have evaluated this issue in any specialty, including pediatrics. We sought to quantify the proportion of time spent by residents in direct care, indirect care activities, and education across 9 pediatric institutions.

Methods

We conducted time-motion observations on the pediatric wards of 9 hospitals. Institutional review board approval was granted by the coordinating center (Boston Children's Hospital; no data were collected at this site) and institutional review board approval was also obtained at all 9 data collection institutions. Activities were categorized using a physician task list previously adapted for pediatric inpatient use.5,6 Time-motion observations were scheduled to occur on a representative ratio of hours from all 24 hours of the day, and weekday vs weekend days, divided between interns and supervising residents. During observations, research assistants followed a single intern or resident, recording start and stop times for activities using a time-motion database on a tablet-based Microsoft Access database of 12 major activity categories and 114 minor activities. To compare the percentage of time in activities between groups, we used a generalized estimating equation z test, accounting for clustering by observation session with a fixed effect for site, using a Dirichlet distribution (a statistical distribution for a continuous variable—in this case time—across multiple categories—in this case activities).

Results

A total of 3452 hours of time-motion data were collected. Across all sites and levels of training, trainees spent more time in interprofessional communication (34.7%), and at the computer (20.5%), and less time in contact with patients and families (12.0%) and in educational activities (4.7%) (Figure). Residents spent more time than interns in interprofessional communication (38.3% vs 31.1%, P = .001) and less time in contact with patients and families (10.3% vs 13.7%, P < .001). During the night, less time was spent in interprofessional communication (29.5% vs 39.3%, P < .001) and education (1.5% vs 7.6%, P < .001) than during the day, with more time spent in contact with patients and families (13.8% vs 10.2%, P < .001). Less time was spent on the weekends in education (1.4% vs 6.2%, P < .001) and interprofessional communication (29.9% vs 36.7%, P = .007) (Table).

Major activity categories included subactivities as follows: waiting for something to respond or arrive (computer, paper, patient, telephone), looking for items or people (colleague, consultant, nurse, patient, supplies, telephone, computer, or patient medical record information), paper-write (writing notes on the printed handoff document; handwritten patient notes, orders, or prescriptions), paper-read (reviewing printed handoff document or part of patient record printed on paper, reading reference materials), education (formal education such as grand rounds or didactic lectures, informal medical education such as learning about a disease process during patient rounds, or patient service learning such as learning how to order a test in the electronic medical record, teaching medical students or residents medical information or patient service activities), telephone (answering or reading pager, paging colleague, getting results, scheduling a test/appointment, telephone call with patient/family members, physicians, nurses, medical students, other staff, or personal telephone calls), patient/family contact (taking patient history, casual conversation, physical examination, explaining the plan of care, educating patient, obtaining consent, discussing advance directives, or conducting medical procedures), personal (eating, sleeping, idle, walking, restroom, talking, personal texting/mobile telephone use, in call room, or donning contact precautions), computer-write (typing into the handoff document, email, sending a text page, writing patient notes, discharge summaries, orders, prescriptions, or incident reports), computer-read (reviewing computerized sign-out, patient record, electrocardiograms, chest radiography, or other patient information; reading email, reference articles, or other online reference material), and interprofessional communication (giving or receiving sign-out; listening to patient presentations or communicating with nurses, medical students, physicians, other staff, or multiple people).

Discussion

In 9 pediatric hospitals, residents spent a large proportion of time in interprofessional communication and at the computer, and relatively little time in direct patient care and education. Trainees working nights and weekends spent more time in direct care and interns spent more time than supervising residents. Time spent in education was particularly low on weekends and nights.

The time pediatric trainees spent at the bedside was similar to that reported in internal medicine studies, but our trainees spent less time at the computer.3,4 Education time was less than found by Block et al3 (where nonbedside rounds was counted as education). We considered nonbedside rounds to be interprofessional communication except during moments when explicit teaching occurred.

Defining time allocation precisely is complex. For example, education and interprofessional communication may occur simultaneously during rounds, but time-motion analysis does not account well for multitasking, a limitation of our study. Additional limitations are the potential for a Hawthorne effect and that observations were restricted to the inpatient setting.

Overall, it is concerning that pediatric residents spend relatively little time at patients’ bedsides, despite the centrality of direct patient care to their training, as well as to families’ care experiences. Further, though residency has become more shift-based, education time at night remains disproportionately low. Increasing attention to resident activities throughout the day and night is needed to prioritize direct patient care and education.
