Health care is changing! The push for decreased healthcare costs with same or better outcomes has led to increased research and implementation of cost-efficient healthcare strategies. An example of a potentially cost-efficient strategy is telehealth. “Telehealth is the use of electronic communication to remotely provide health care information and services” (APTA). More specifically, telemedicine is the exchange of medical information, while telerehabilitation is the delivery of rehabilitation services. These services may include assessment, monitoring, prevention, intervention, supervision, education, consultation and counseling. Some benefits to telehealth are increased accessibility to healthcare for patients in rural areas, and time and cost efficiency. In order to practice telerehabilitation, national and state legislation, and insurance coverage terms need to be considered. For more information on telehealth, visit the American Physical Therapy Association website (www.apta.org/Telehealth/).
A study was conducted in Sweden from December 2009 to April 2013, to examine the short and long term outcomes of an internet-based treatment program for stress urinary incontinence (SUI) compared to a treatment program sent by post. The results of the study were published in two separate articles in 2013 and 2015. The following is a review of both articles.
Method
Recruitment/Selection
Participants were recruited via advertisements published on medical-related websites and in daily newspapers. Interested women were required to answer a 17-item survey that included the Incontinence Severity Index and questions on type of urinary incontinence (UI) to determine eligibility. The questions were posted on an open access website dedicated to the study. Two hundred and fifty participants were found eligible and underwent baseline assessments. Data on medical history, socio-economic status, internet usage, motivation and symptoms of anxiety and depression were collected with a questionnaire. The eligible women also completed the standardized outcome measures for the study and 2-day bladder diaries. In addition, over-the-phone interviews were conducted by a urotherapist.
Participants were randomized into two treatment groups, 124 into the internet-based arm of the study (mean age, 47.9 years), and 126 into the postal treatment arm (mean age, 49.8 years). There was no masking of the participants, healthcare providers or researchers involved in the study. The duration of intervention for both groups was three months, and the programs were comprised of information on SUI and pelvic floor muscle training (PFMT). Adherence to training- frequency and duration of PFMT- was tracked in both groups. The internet-based group was provided login information through which they could access training information. Their program was divided into eight levels, and though they could self-progress their PFMT, only two levels could be accessed at a time. Furthermore, participants in this group completed weekly evaluations and training diaries that were submitted to urotherapists. They could also contact the urotherapists for information via encrypted e-mail.
Treatment Programs
The participants in the postal group were provided with all exercises at the start of the study with instructions to self-progress the exercises. They did not receive support from the urotherapists, and were only required to submit their training reports at the first follow-up (after four months). Their information was sent via postal means, and they had no face-to-face contact with the researchers or email support.
The treatment program included:
- Illustrations
- Maximal contractions for strength: 8s x 8-10 reps x 3 times daily
- Submaximal contractions for endurance: 15 to 90s x 1 rep x 3 times daily
- Quick contractions: 3s x 8-10 reps x 2-3 times daily
- The “Knack”: pelvic floor contraction prior to and during exertion
- Cognitive behavioral technique (CBT) assignments (if applicable): lifestyle change, identification and change in behaviors of avoidance and redundant security measures
- Weekly training report
- Email support by urotherapist
*The postal group received all but the last three parts of the treatment program.
Outcome Measures
The primary outcome measures were the Incontinence Questionnaire Short Form (ICIQ-UI SF) and ICIQ-LUTSQoL. Frequency, amount of leakage and impact on quality of life were measured using the ICIQ-UI SF, and symptom specific quality of life (QoL) was measured using the ICIQ-LUTSQoL. Higher scores on these measures indicate increased severity and impact on QoL respectively. Secondary outcome measures included the patient global impression of improvement (PGI-I), health related Qol (EuroQoL), incontinence episode frequency (IEF) calculated from the 2-day bladder diaries, usage of urinary aids, and satisfaction with the treatment program. Data on primary and secondary outcomes were collected at baseline, four months, one and two years.
Results
The groups were homogeneous at baseline for demographics and primary outcome measures.
4-month follow–up
At four-months follow-up, 107 and 113 participants in the internet-based and postal treatment groups respectively completed the follow-up.
Primary Outcomes: Both groups demonstrated statistically significant improvement in all primary outcomes, with no significant differences between groups. However, when considering only the severity of leakage measured by the ICIQ-UI SF, participants with severe leakage at baseline in the internet-based group had significant improvement compared to those in the postal group.
Secondary outcomes: More subjects in the Internet group reported leakage after treatment as “much better” or “very much better” when compared to those in the postal group. This was statistically significant. The number of UI episodes per week (IEF) was significantly decreased within both groups, with significant differences between groups, favoring the Internet group. Usage of incontinence aids was also significantly different between groups, the Internet group reported use of less aids post-intervention.
One and two–year follow–ups
At one-year follow-up, 88 women in the Internet group and 81 in the postal groups completed the assessments. Of the 167 participants remaining after one year, 9.6% had sought other treatments for SUI, but were still included in the analyses. After two years, 75 and 80 participants were left in the Internet and postal groups respectively. Approximately 12.3% had sought other treatments.
Primary Outcomes: There were significant within group improvements compared to baseline but no significant between group differences, after one and two years.
Secondary Outcomes: Reported improvement in leakage was not statistically different between groups at one-year follow-up. However, the internet group had a significant improvement in leakage compared to the postal group at the two-year follow-up. Health related QoL did not improve significantly in either group after one year, but there was a significant improvement after two years in the internet group. There were no between group differences in health related QoL at one- and two-year follow-ups.The proportion of participants using incontinence aids at one- and two-year follow-up decreased significantly within groups. More participants in the internet group after one year and two years reported satisfaction with treatment results, but there were no between group differences. The authors reported that separate analyses excluding those who underwent surgery during follow-up period yielded similar results.
The results of the study are interesting and support the use of telehealth and even postal treatment programs in the management of SUI for short and long term positive outcomes. However, there were several limitations to the study. First, the authors compared two remote strategies. Further research would be needed to compare internet-based care to face-to-face, and a postal treatment program to face-to-face care. In addition, participants who dropped out of the study had more severe UI and were younger. Women included in this study also had to have access to the internet. Therefore, research to identify characteristics of patients who will benefit from this form of management would be beneficial. With the changing climate of healthcare, strategies that can potentially decrease costs and still provide significant positive outcomes in the short and long terms will be of great value.
In some parts of the United States, patients seeking physical therapy management for UI have to travel long distances to see a physical therapist. With telehealth they may only need to travel once or even not at all for an assessment and to continue via the internet. In other clinics there are long waitlists for women’s and pelvic health specialists. In these situations, telehealth may decrease the burden on patients and on therapists. Patients in rural areas would be able to access care from expert women’s health and pelvic health therapists. With further research and changes in current legislation and insurance reimbursement, telerehabilitation could have a place in the management of stress urinary incontinence.
