Table 5 Data Model for evaluating outcomes and objectives

From: Design of a multi-site multi-state clinical trial of home monitoring of chronic disease in the community in Australia

Objective/outcome Data variable Data source
Define the study cohort/confirmation of selection critera and exclusions Admitted to hospital for their condition at least twice in the previous year, or ≥ 4 times in previous five years Hospital health roundtable records - obtained from local hospital for previous five years.
   • Date admitted
  Exclusions are mental health and cancer patients • Date discharged
• Reason for admission (ICD 9/10 Codes)
• Procedures carried out
Establish if telehealth Number of unscheduled admissions to hospital for their condition MBS Flag (In hospital) Health roundtable record
Improves patient outcomes/reduced hospitalisation   • Date admitted
• Date discharged
• Reason for admission (ICD 9/10 Classification)
• Medication administered
• Procedures carried out
Establish If telehealth improves patient outcomes/reduced use of clinical services (Impact on clinical workforce availability and deployment) Number of visits to/by GP MBS records
Number of visits to/by specialists MBS records
Number of visits by community nurse MBS records
Number of visits to/by allied health (ie occupational therapist) MBS records (If reimbursable from Medicare)
Changes in prescription history PBS
Communication with CCC CCC Logs from CSIRO Portal
Organisational change management and impact on workplace culture Administrative/operational changes implemented/required in order to implement the Telehealth service. Questionnaires and structured interviews.
• Within first three months
• Every six months thereafter
Useability of monitoring equipment Compliance with monitoring schedule, recorded daily. TMC Logs
Extra measurements taken by patient (When? Which?) TMC Logs
Compliance with questionnaire administration (When? Which?) TMC Logs
Use of video conferencing TMC Logs
Overall data usage iiNET provided logs
Useability/acceptability Ease of use Questionnaires delivered via TMC
For patients of monitoring Equipment Quality of training received • One month after first deployment
Patient embarrassment if visitors know they are being monitored • Midpoint of trial
Acceptability as an item of furniture • At end of trial
Easy or hard to take measurement
Important/not important in patients' self management
Responsiveness of clinical care coordinator in responding to changes
Quality of training received
Patient embarrassment if visitors know they are being monitored?
Easy or hard to take measurement
Carers experience with telehealth (Community nurse/carer) Ease of use of (i) equipment and (ii) Clinician website Questionnaires and structured interviews of community nurses

Effectiveness in improving ability to deliver care • Midpoint of trial
Impact on workload • At end of trial
Useability, acceptability of clinician web interface Ease of use? Questionnaires and structured interviews
Quality of training received • One month after first deployment
How many hours required • Midpoint of trial
Value and ease of use of Video conferencing • At end of trial
Health economic outcomes Daily cost of hospitalisation Health roundtable data
Cost of procedures carried out whilst in hospital Health roundtable data
Cost of visits to/by GP MBS Data
Cost of visits to/by Allied Health (ie Chiropodist or OT) MBS Data
Cost of visits by community Nurse/carer MBS Data
Cost of travel to GP MBS Data
Loss of earnings if patient is still employed, from days taken off for illness or visits to health professionals Use Google Maps to determine distance travelled from home address to address of service location, then apply standard costing model. Ie flag fall + km charge.
Estimate from patient salary and time spent on each visit
Cost of delivering telehealth services Cost of clinical care coordinator(s) Health service provider and logs recorded
Cost of clinical nurses/carers Health service provider and logs recorded
  Cost of providing network services iiNET billing at commercial rates
  Cost of providing Telehealth monitoring services TMC commercial daily subscription costs
  Depreciated costs of capital equipment Our own project records
