Abstract
Developmental dysplasia of the hip (DDH) is the most common paediatric hip condition and is a major cause of hip replacement or osteoarthritis in young adults. Due to potential impact on quality of life, every child is checked at birth for unstable hips. Should instability be detected, or the infant has other DDH risk factors, they are referred for an ultrasound exam and orthopaedic surgeon consultation.
Since the implementation of a DDH screening program at our institution, the Radiology Department has seen a dramatic increase in hip ultrasounds performed. While helping prevent the complications of missed DDH diagnoses, this program has placed strain on radiology resources, and often families must attend multiple appointments before receiving a diagnosis and beginning treatment. To mitigate this, we have implemented a pilot point-of-care DDH clinic, where an ultrasound technician performs hip ultrasound exams using a portable ultrasound in the orthopaedic clinic in conjunction with surgeon consultation. The aim of this clinic is to enable diagnosis and treatment in one appointment, reduce referral-to-treatment delays, wait times, and decrease costs and travel time for families while also alleviating strain on radiology resources.
A point-of-care DDH test clinic was implemented in the Orthopaedic Department at our institution. Patients referred with suspected/confirmed DDH attended a single orthopaedic clinic appointment. An ultrasound technician was present to perform scans in conjunction with the orthopaedic surgeon's clinical assessment. Surveys were distributed at the end of the appointment to collect feedback on the family's satisfaction with the program, as well as other pertinent demographic information (i.e. occupation, geographic location, travel time to hospital).
To date, 40 patients have attended the pilot clinic. Families spent an average 61.3 minutes (range 15–420 minutes) traveling to the hospital for an appointment (122.6 minutes round-trip). This program reduced the number of hospital visits for DDH screening from three (initial consultation, radiology, follow-up) to one per patient, saving an average 245.2 minutes of travel time to/from the hospital per family. Appointment time averaged 35.9 minutes and families rated their satisfaction with appointment length an average of 9.6/10 (35/40 families rated satisfaction 10/10, 1 = very unsatisfied, 10 = very satisfied). Additionally, 33/40 families were also asked to rate their satisfaction with check-in/check-out processes (average 9.4/10), ultrasound screening (average 9.9/10), and time with specialist (average 9.9/10). Satisfaction scores did not differ based on variables such as survey taker's gender, occupation, or geographic location.
The pilot point-of-care ultrasound DDH clinic has considerably reduced the number of clinic visits and travel time for families, reduced aggregate clinic wait times, and has resulted in high family satisfaction. This specialized clinic may have potential to free up hospital staff time and resources, possibly decreasing wait times in other clinical areas, ultimately improving quality of care for patients and families across our institution.
