Public title
Impact of population-based disease management services (encompassing population analytics and telephone health coaching) on cost and hospitalisation for privately insured Australians with selected chronic conditions
Scientific title
A randomised control trial to evaluate the ability of a full service disease management program (encompassing population analytics and telephone health coaching), in comparison to simple program awareness building, to impact on subsequent health care costs and hospitalization for privately insured individuals with specific conditions and identified risks.

Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Disease management services from Bupa Health Dialog including mailed program awareness notifications, tailored mailed educational material, tailored outreach material designed to encourage individuals with specific risks to talk with a Health Coach, outbound Health Coach outreach and follow-up calls (a minimum of two calls in first two months with no maximum number of calls being set), access on an inbound telephonic basis to Health Coaches, and mailed Health Coach selected educational and other material.

Duration of the intervention is for 12 months.

Comparator / control treatment
The control group will receive usual care unless they “opt-in” to receive health coaching.

Individuals randomly assigned to the Control Group will receive a letter outlining the service provided by BUPA Health Dialog. This letter will contain a phone number that participants may choose to ring should they wish to receive health coaching. Put simply, a health coach will not ring the participant directly.

If a participant assigned to the usual support group actively seeks health coach engagement, they will receive the same service provided to a participant assigned to the intervention group i.e. health coaching. Health coaches will have information available about the members derived from claims data and will have all the same educational resources at their disposal as they do for the intervention group. The health coaches will not have specific information that identifies control group members as such. Regardless of level of interaction with health coaches, all individuals assigned to the Control will be analysed as such.

It is worth noting that experience in other settings leads us to believe that the proportions of individuals who will actively seek Health Coach engagement with mailed outreach only will be very small, 3% or less. This will enable the differentiation of service levels between the intervention and control to be quite high. To ensure this is the case in the Australian setting, the number of members falling into this category will be reviewed on a six monthly basis.

Outcomes
Primary outcome [1] 266744 0
The primary outcome measure is the total (non-maternity) cost for health fund members. Cost in this study is measured from the perspective of a private health insurer. That being, the total benefit paid calculated as the summation of hospital, medical (excluding Medicare component) and prostheses. Ancillary benefits will not be included as the role of the intervention in impacting on a range of benefits including dental and optical is not sufficiently well defined.

Prevention
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Subjects are identified for enrolment each month based on qualification of inclusion criteria including a minimum risk score of 0.061. This is equivalent to a predicted cost for the following 12 months of $3,050 or more.

Risk scores are recalculated monthly based on new claims data that becomes available. Each month, a sample of subjects who meet the inclusion criteria are randomly selected using SAS Surveyselect procedure (SAS statistical software version 9.1.3). The proportion selected from those who meet the inclusion criteria is dependent on the capacity of the health coaches.

A total target population of at least 36,000 recruited; a sampling ratio of 4 intervention group participants for every one control group participants.

A stratified random allocation design is used to produce concordance between the intervention and control groups on baseline demographics and risk score. The strata selected for the randomisation are the five chronic conditions.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Randomisation was created using SAS Surveyselect procedure (SAS statistical software version 9.1.3) with the default simple random sampling option and stratified by chronic condition with a 4:1 allocation ratio to intervention
and control.

For each monthly batch of data, a seed value of nine digits was obtained by the statistician using random number generator with replacement from 0 to 9 for each of the nine digits. The Surveyselect procedure generates uniform random numbers using a prime modulus multiplicative generator with modulus 231 and multiplier 397204094. This means that it is very unlikely randomisation will be repeated.
