Research Purpose:

To examine management outcome of home parenteral nutrition (HPN) patients when followed by telehealth as an alternative modality of care with a survey.

Inclusion Criteria:
  • Referred to telehealth video-conferencing
  • Home parenteral nutrition patient and part of the HPN program
  • Unable to travel to Toronto General Hospital (TGH) due to cost, weather or distance.
Exclusion Criteria:

Not described.

Description of Study Protocol:

Recruitment

  • Patients were referred to telehealth video-conferencing when they were unable to travel to TGH due to cost, weather or distance
  • The HPN nurse clinician requested consultations through the UHN telehealth department
  • The online consultation request form includes contact information, diagnosis, distant-site care providers and physical assessment data to be completed before the scheduled sessions.

Design

Before and after study.

Blinding Used

Implied with measurements.

Intervention

30-minute telehealth session.

Statistical Analysis

  • Cost analysis of telehealth infrastructure, which was based on three items: Technology, human resources and infrastructure
  • Satisfaction survey, which included ordinal scale responses (always, usually, sometimes and never).
Data Collection Summary:

Timing of Measurements

Measurements made before and after telehealth sessions.

Dependent Variables

  • Line sepsis rate: Measured by a survey question that focused on catheter complication within the past three years of telehealth. Patients were also asked about other complications related to HPN medical management such as central line replacements, dehydrations and physician visits related to HPN.
  • Cost analysis of telehealth consultation, based on technology, human resources and infrastructure: For human resources, the salaries of the telehealth technician and administration staff of the remote site were considered, as well as the salaries of the multi-disciplinary staff (nurse, dietitian and pharmacist).

Independent Variables

  • Telehealth satisfaction: Assessed using a 10-item data collection form during telehealth sessions, which provided information on the type of consultation, data about the distant site, family or caregiver presence, data about our base site, the time it took for each member to interact with the patient, the types of assessment including review of patient history from the last visit, discussion of results and treatment options
  • Patient assessment: Including inspection and examination over interactive video using a digital camera
  • Nutrition support team completes the parenteral nutrition (PN) clinic flow sheet and the physician summarizes the session, which includes the treatment plan to be integrated in the ambulatory patient chart before leaving the video-conference session
  • Patient satisfaction survey: Completed by patients by mail. The survey consisted of 18 questions that used the Likert scale to evaluate whether or not the patient was able to talk with the PN team about their most important concerns and if they were involved with care as much as possible.
Description of Actual Data Sample:
  • Initial N: 21 subjects receiving telehealth, but only 13 subjects eligible to receive survey
  • Attrition (final N): 13 subjects (nine women, four men)
  • Age: 24 years to 75 years
  • Ethnicity: Not described
  • Other relevant demographics: Not reported
  • Anthropometrics: Not reported
  • Location: Toronto, Ontario, Canada.
Summary of Results:

Key Findings

  • The satisfaction survey response rate was impressive, with a return rate of 11 out of 13 (84.6%)
  • All patients were generally satisfied with video-conferencing as an alternative method of communication and care for new consultation, patient and family education and follow-up
  • The average line sepsis rate for the 13 patients was 0.89 per 1,000 catheter-days.

 Other Findings

  • Travel time and costs to the patients, their families and the health care system were significantly less, since a patient residing 611km away would spend $724 Canadian for a flight and accommodations to meet with the healthcare team in Toronto
  • The estimated cost of a telehealth consultation for a home parenteral nutrition patient in 2005 was $203.66 Canadian per session.   
Author Conclusion:
  • This study suggests that telehealth lowered costs to both the rural patient and health care system, while providing increased satisfaction
  • Overall, the effect of telehealth in HPN deserves further consideration for a national application.

Reviewer Comments:

The authors acknowledge a small sample size, but found no increase in line sepsis rates with these patients, compared with evidence-based literature studies defining line sepsis rates of 1.2 per 1,000 catheter-days.

Relevance Questions
  1. Would implementing the studied intervention or procedure (if found successful) result in improved outcomes for the patients/clients/population group? (Not Applicable for some epidemiological studies) Yes
  2. Did the authors study an outcome (dependent variable) or topic that the patients/clients/population group would care about? Yes
  3. Is the focus of the intervention or procedure (independent variable) or topic of study a common issue of concern to dieteticspractice? Yes
  4. Is the intervention or procedure feasible? (NA for some epidemiological studies) Yes
