Brief Summary:
In a Pilot Study the median Wheelchair Lead Time from when a wheelchair was ordered by an Occupational Therapist for an inpatient in the Central Zone of Nova Scotia Health to when the wheelchair arrived at the destination facility of 119 wheelchairs was 298 days with median Wheelchair Assembly Time and Wheelchair Delivery Time components of 098 and 100 days respectively For the over 3000 inpatientsyear for whom an order is placed Wheelchair Delivery Time is not routinely recorded Reductions in Wheelchair Lead Time have the potential to speed patient mobilization with benefits to the patient and reduce both the patients hospital Length of Stay and the patient-related Cost of Hospitalization However these potential benefits remain speculative The objective of this project is to test the hypotheses that there are significant positive associations between Wheelchair Lead Time and both Length of Stay and the Cost of Hospitalization
Detailed Description:
The wheelchair provision process within the Central Zone of Nova Scotia Health includes the ordering assembly and delivery of wheelchairs from where the inventory is stored at the Nova Scotia Rehabilitation and Arthritis Centre to inpatient units at 10 sites At discharge from hospital the wheelchair is typically returned cleaned and placed back in inventory The WheelEase software that tracks components of this process was developed locally in 2001 ownership of which has transferred to the Nova Scotia Health Assistive Technology Program The software has been periodically refined As an indication of the volume or orders during the 6-month period from April 1 to September 30 2021 there were 257-277 orders per month 13weekday and the WheelEase database includes over 34000 historical wheelchair orders People who require wheelchairs after discharge need to rent or purchase them a process that can take several months
During the 2022-2023 Academic Year the Wheelchair Research Team proposed and directed a Pilot Study by a group of four final-year Industrial Engineering students The objective of the Capstone Project was to analyze Nova Scotia Healths wheelchair provision process for inpatients in the Central Zone and provide recommendations that might improve the quality of care provided and save costs The students used a variety of methods to collect data including regularly checking loading docks and delivery spaces tracker sheets Global Positioning System trackers interviews contextual inquiry and shadowing of wheelchair technicians a survey of Occupational Therapists of whom there were 64 in the Central Zone a discrete-event simulation to compare sequencing rules for the order in which the technicians build wheelchairs and a review of the existing WheelEase database
Among other findings from the Pilot Study during an 11-weekday period in late January 2023 the median Wheelchair Lead Time of 119 wheelchairs was 298 days with median Wheelchair Assembly Time and Wheelchair Delivery Time components of 098 and 100 days respectively Variations among sites and the day of the week that the order was placed were identified The average 24-hour cost of a hospital bed in the Central Zone was 1101 range 557-1313
By comparison in a quality-improvement project on 750 inpatients with spinal cord injury in a large American hospital Taylor et al reported that patients with cervical-level injury had the highest mean wait times 828 days for powered wheelchairs and the second highest was for manual rigid-frame wheelchairs 629 days Other studies have found that the early mobilization of patients can lead to reductions in medical complications lengths of stay and costs
In summary reductions in the Wheelchair Lead Time could speed patient mobilization with benefits to the patient and reduce the patients hospital Length of Stay and the patient-related Cost of Hospitalization However at this time these potential benefits remain speculative The objectives for this Project are to test the hypotheses that there are positive correlations between Wheelchair Lead Time and both Length of Stay and the Cost of Hospitalization
METHODS
Sample size Of the 119 patients available from the Pilot Study the investigators plan to study all who meet the inclusionexclusion criteria
Database extraction The investigators will use the Medical Record Number and WheelEase order number to link extract and deanonymize the data we need from the STAR or Discharge Abstract WheelEase Capstone Pilot Study and Finance Department databases into an Excel file The following data elements will be recorded in a common dataset Medical Record Number WheelEase order number Date of birth Sex Diagnosis accounting for admission Discharge destination Order Origin Order Date and time Order Wheelchair type Assembly Date and time Delivery Date and time and Hospital case cost
Statistical analyses From the date of birth and order date the investigators will calculate the age in years when the order was placed From the dates for the Order Assembly and Delivery events the investigators will determine the days of the week corresponding to those dates From the three events three periods will be calculated Wheelchair Assembly Time from when ordered to assembled Wheelchair Delivery Time from when assembled to delivered and Wheelchair Lead Time from when ordered to delivered All data will be reported descriptively Where appropriate the normality of the quantitative data will be assessed to guide the use of parametric vs nonparametric statistics To test the hypotheses the investigators will use Pearson or Spearman correlation coefficients Secondarily multivariate regression will be carried out with both Length of Stay and Cost of Hospitalization as dependent measures and age sex diagnosis day of week that the order was placed excluding weekends and holidays site and wheelchair type as independent measures The alpha level will be defined as 005 SAS statistical software will be used
Economic analysis Hospital case cost includes all Nova Scotia Health direct indirect and total costs eg bed lab imaging food allied health but excluding physician costs operating-room supplies and days less than 24 hours typically available up to the end of the prior fiscal year March 31 Although the literature suggests that there should be positive patient outcomes resulting from any reductions in Wheelchair Lead Time the investigators will not have data on such outcomes Therefore the economic analysis will be conducted from the perspective of the benefits to society In any healthcare system with financial constraints any system benefits must be weighed against their costs
