Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The intervention is a change in service delivery model. The key changes include: * Introduction of a facility-based general practitioner employed at each site. * A clinical co-ordinator will be appointed at each site from existing staff if possible, to co-ordinate interactions with the general practitioner. The role of the general practitioner at each site will be established and integrated with existing processes and procedures. Communications will be made with existing general practitioners of residents advising them of the change in model of care at each site. In addition to the GP, the additional staff roles being introduced are: * Care manager—“To manage the delivery of person centred care to residents, ensuring the highest standard of ongoing assessment, care planning, evaluation and clinical governance, helping them to live longer, healthier, happier lives.” They will have responsibility for ~40 beds. * Clinical manager—“To support the GP in managing the medical practice, providing expert health services to approximately 150 residents across one or more BUPA care homes. To provide the link between Care Manager and GP in delivery of collaborative, integrated healthcare including assessment, care planning and clinical intervention.” * Registered Nurse in charge—“To supervise the delivery of person centred care to residents, as delegated by the Care Manager, to ensure the highest standard of ongoing assessment, care planning, evaluation and clinical governance, helping residents to live longer, healthier, happier lives.” * Team leader—“To deliver highest quality person centred care to residents, as delegated by the Care Manager/RN in charge. Ensuring safe medication administration, best practice wound care and clinical support for residents within the unit.” Organisational change facilitators will facilitate change in service delivery model at each site within the trial over the initial 63 days of the intervention period. Support will continue to be provided by change facilitators to the respective facility staff over the time period of the intervention, and over the 365 days of prospective follow-up as required. The new GP role is not full time in all facilities, rather, it is proportional to the number of beds at the facility. The new nursing roles will go to current employees if appropriate. The positions will be full time but may include job sharing arrangements.

The medications will no longer be delivered by a registered nurse, dispensing from a medication trolley, rather, they will be pre-packaged, kept in the resident’s room, and residents will be facilitated to take their medications by a personal care attendant. These Personal Care Attendants will be trained to undertake this role. The timing of medication distribution will transition from scheduled rounds at 8am, 12 midday, 6pm, (+ exceptions for particular medications), and towards scheduled rounds at 8am, 2pm, 8pm (+ exceptions for particular medications) with residents providing input where possible as to the timing of their medications.

Study design
Purpose of the study
Prevention
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
In the stepped wedge cluster randomised trial design, all sites involved commence as control sites and transition, in a random order, to becoming intervention sites. The choice of these sites is dictated by organisational imperatives of Bupa, the owners and operators of these sites who wish to transition these sites to the new model of care.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Two investigators will conduct the randomisation of RACF clusters. One investigator will assign mock codes to each of the clusters of sites and then forward the mock codes to a second investigator. The second investigator will assign a computer generated random number to each of the mock codes and, based upon the lowest random number going first, determine the roll-out sequence relative to the mock codes. This sequence will then be forwarded back to the first investigator who will be able to connect the actual site locations to the mock codes. Thus the person conducting the allocation will not be aware of which site is which.

Other design features
Stepped-wedge, cluster randomized controlled trial. the RACF clusters are randomly allocated to a different starting position for roll out of the intervention at those sites. The roll out period for each the clusters of RACFs, when the GP will begin employment and organisational arrangements put in place to support this, will commence seven weeks after commencement of roll out at the previous cluster, commencing in February/March 2013. The roll-out will take seven weeks from commencement to completion of roll-out. A 2 week break period will be employed between completion of roll-out at one site, and commencement of roll-out at the next site. Thus a 9 week / 63 day observation period will be observed for each step. The stepped-wedge trial will last for 504 days, following which there will be 365 days of prospective follow-up.

Efficacy
Statistical methods / analysis
Linear mixed model analyses will be conducted for each outcome where assessments (data broken into 7 week blocks) are nested within the residents, residents are nested within sites and sites are nested within clusters and each are treated as random effects indicating that they are representative of a broader population of time points, residents, and nursing facilities. The intervention will be considered as a fixed effect (i.e. that it has not been drawn from a broader population of interventions, rather, that it is a specific intervention of interest). Two styles of analysis will be undertaken. The first will only involve data from the stepped-wedge cluster RCT design. The “roll-out” block for each site and the 9 week block following this will be excluded from the analysis in each case as although the intervention has commenced at each site, it is not yet fully instituted (this time that will be excluded from the analysis is not included in the 504 day time period of the stepped-wedge trial). A total of 18 weeks of "block-out" time is required to ensure that there is sufficient time for staff at each site to be trained, for a suitable general practitioner to be recruited, for them to give notice for leaving their previous employment and commencing at the research site. Intervention by time interaction effects will also be examined. Secondary analyses will be conducted that incorporate 12 months of retrospectively collected, pre-trial data, and 12 months of prospectively collected post-trial data. Economic analysis The health economics analyses will include investigations of reductions in direct medical costs foreseen due to changes in the rates of hospital admissions, infections, ER visits, afterhours consultations, medication usage (all types including antibiotics, psychotropic, analgesic etc.) and supplemental feeds; and reductions in indirect costs due to lost productivity that are envisaged with increased staff satisfaction leading to decreased sick leave and staff turnover, as well as decreased time spent on resolution of care and GP-related complaints. These costs will offset to some extent the salary costs of employing resident GPs. Medicare billing for consultations and procedures will similarly be quantified to calculate additional offset of salary costs. Health economics analyses will include the evolution of direct and indirect costs for intervention versus control over time. Units of resource consumption will be combined with Australian unit costs to calculate direct medical costs. For example published Pharmaceutical Benefits Scheme medication cost data will be combined with medication usage data from patient records to calculate costs of medications. Medical Benefits Scheme item numbers and reimbursement values will be combined medical consultations, procedures and investigations to calculate the total costs of these items. In the case of hospitalizations, several methods will be employed. As a first pass, Australian Diagnosis-Related Group costs will be used, based on the diagnosis of the condition that led to a hospital separation. A weakness of doing this is that for aged care residents, the average length of stay is likely to be higher than the average length of stay used to calculate the A-DRG costs. To address this, the number of days in hospital will be recorded by BUPA for each hospitalization separation. This information is currently already captured in the patient records. This information will be used to up-scale the hoteling and other relevant part of the DRG cost where appropriate to partially account for the higher costs of aged care residents’ hospitalisation costs. The benefits of this approach are: 1. that it will utilize routinely collected information easily available to BUPA, without having to gain patient consent, as would be required if a detailed hospital patient record analysis was performed; 2. and as the information is already currently collected by BUPA, there will be no additional research costs. To further account for uncertainty relating to hospitalization costs, sensitivity analysis will be performed using different hospitalization-related cost assumptions, varying costs within plausible ranges. The impact of doing this on the total costs for the intervention and control arms will be assessed. Changes in indirect costs due to lost staff productivity will be assessed using human resource data routinely collected by BUPA. Days off work will be combined with daily salary to estimate the value of lost productivity from sick leave. Descriptive and comparative statistical analyses will be performed. Cost-consequence analyses will summarize the direct, indirect and total costs per resident in each treatment arm, as well as the differences in these costs between each treatment arm. Further analyses may include cost-benefit ratio (return on investment) and incremental cost-effectiveness ratio. As health utility data have not been and will not be collected, it will not be possible to calculated costs per quality-adjusted life years gained.
