Hearing health-care delivery in sub-Saharan Africa - a role for tele-audiology

ons, 24/02/2010 - 23:33

Hearing loss is the most prevalent chronic disability and a major contributor to the global burden of disease. Its effects are far-reaching and can lead to severely restricted developmental outcomes for children and limited vocational prospects for adults. The benefits of intervention are dramatic and can significantly improve developmental outcomes, especially in infants identified early. Hearing health-care services in developing regions such as sub-Saharan Africa are however severely limited, leaving affected individuals without access to secondary and tertiary intervention. Tele-audiology has potential for improved access to specialist hearing health services including identification, diagnosis and intervention. There has been limited experience so far with tele-audiology in industrialized countries. In the sub-Saharan region, the continued growth in Internet connectivity and general technological advances make tele-audiology an important approach to consider in the management of hearing loss. Pilot studies are warranted to investigate the potential obstacles to the widespread implementation of telehealth in the delivery of hearing health care in poorly-resourced communities, in line with World Health Organization initiatives.

Telephone-supported care coordination in an Australian veterans population: a randomized controlled trial

ons, 24/02/2010 - 23:33

An evaluation was undertaken on the effectiveness and efficiency of care coordination in delivering health services to Australian veterans with chronic or complex medical conditions requiring multidisciplinary care and who had moderate to high care needs. The veterans participated in a randomized controlled trial (RCT) supported by the Department of Veterans' Affairs. For evaluation of the RCT, information on cost of care and quality of life (QOL) was collected before the commencement of coordinated care and at follow-up after 12 months. Of 525 veterans who were recruited, 481 were surveyed at baseline (243 in the intervention group and 238 controls). At follow-up, 421 were surveyed (213 intervention and 208 controls). There were no significant differences between the coordinated care and control groups of veterans in costs of care or in QOL measurements using the SF-12 Health Survey and the EuroQol Group EQ-5D. These findings are consistent with those reported in earlier studies which suggest that benefits from care coordination programmes may take some time to emerge.

Cost-effectiveness of a community-based obesity control programme

ons, 24/02/2010 - 23:33

We evaluated two 12-week long community-based obesity control programmes in Korea. One was a visiting-type programme (V-type) (n = 515) administered by a public health centre and the other was a remote-type programme (R-type) (n = 410) utilizing an Internet website and mobile phones with a short message service. The total cost for the intention-to-treat subjects was US$116,993 in the V-type programme and $24,555 in the R-type programme. In the per-protocol subjects, 66% of V-type participants (n = 117) achieved the target bodyweight reduction (5%) and 13% of R-type participants (n = 15). In the per-protocol subjects, the cost per person was $227 (V-type) and $60 (R-type). The cost per person achieving the target weight reduction was $975 (V-type) and $1637 (R-type). The average amount that participants were willing to pay was $71 (V-type) and $21 (R-type). The cost-effectiveness of the visiting-type community-based, short-duration obesity control programme was higher than the remote-type programme.

Home telemonitoring for congestive heart failure: a systematic review and meta-analysis

ons, 24/02/2010 - 23:33

We conducted a systematic review of the literature about home telemonitoring compared with usual care. An electronic literature search was conducted to identify studies of home telemonitoring use in congestive heart failure (CHF) patients. Twenty-one original studies on home telemonitoring for patients with CHF were included (3082 patients). A random effects model was used to compute treatment efficacy to measure the average effect of the intervention across all studies where the quantitative pooling of results was appropriate. Home telemonitoring reduced mortality (risk ratio = 0.64; 95% CI: 0.48–0.85) compared with usual care. Several studies suggested that home telemonitoring also helped to lower the number of hospitalizations and the use of other health services. Patient quality of life and satisfaction with home telemonitoring were similar or better than with usual care. More studies of higher methodological quality are required to give more precise information about the potential clinical effectiveness of home telehealth interventions.

Expert visual guidance of ultrasound for telemedicine

ons, 24/02/2010 - 23:33

Expert visual guidance (EVG) is computer assistance that displays to the examiner how the image plane moves towards (or away from) a desired anatomical location as the ultrasound probe is manipulated over the patient's body. We tested whether EVG by a remote expert could assist inexperienced examiners in acquiring abdominal ultrasound images. The inexperienced examiners were 20 medical students, who were randomly assigned to verbal instruction alone (Group 1) or to EVG (Group 2). The examiners were tested on their ability to visualize the abdominal aorta and the right kidney. Group 2 was more successful in identifying specified anatomy in longitudinal and cross-sectional views of the aorta (95 vs. 75%, P = 0.032) and kidney (98 vs. 88%, P = 0.09). The groups succeeded equally well in obtaining a true cross-sectional view of the aorta. Kidney length was also similar when measured by the two groups. The results demonstrate that an inexperienced ultrasonographer can be significantly assisted by EVG compared to verbal instruction alone. This could be useful for tele-mentoring in rural hospitals as well as for teaching, both in person and at a remote site.

A pilot trial of telemedicine-assisted, integrated care for patients with advanced amyotrophic lateral sclerosis and their caregivers

ons, 24/02/2010 - 23:33

Patients with amyotrophic lateral sclerosis (ALS) need a care programme as the disease progresses. We used telemedicine-assisted integrated care (TAIC) in 40 patients with ALS, for a mean duration of 8.6 months (range 1–12). A nurse-tutor played the key role, supported by respiratory physicians, neurologists and psychologists. Each patient used a portable pulse oximeter during the daily telephone contacts to assess clinical/oxygen variations. Patients also completed a satisfaction questionnaire. During the study period, each patient used TAIC at least five times per month. There were 1907 scheduled telephone calls (86% of the total) and 317 unscheduled calls. Of the unscheduled calls, 84% were managed by the nurse-tutor and only 16% of them required specialist intervention. The most common item was the ALS clinical interview (58%), followed by the description of acute symptoms, cough ability and oxygenation. TAIC staff recommended 4 out of 12 emergency hospital admissions (33%) and 77% of the other hospitalizations. Patients and caregivers were extremely satisfied (79%) with the nurse assistance provided and the patients' confidence in handling their disease improved in 71% of the cases. TAIC provides a nurse-centred, home-monitoring programme that can be a useful way of following up ALS patients.

Costs and benefits of tele-endoscopy clinics in a remote location

ons, 24/02/2010 - 23:33

We assessed the cost and benefits of tele-endoscopy clinics in a remote location in Scotland. Before the introduction of a tele-endoscopy service, patients whose symptoms suggested possible cancer of the airways had to travel to the mainland (to Aberdeen) to receive an endoscopy. The costs of staff, capital, disposables and travel were estimated for the tele-endoscopy clinic and for the conventional, mainland clinic. The benefits of the two types of clinic were estimated from a sample of the general public using a survey method called the discrete choice experiment. The average cost per patient was lower for the tele-endoscopy clinic (£353) than for the mainland clinic (£381). This was true if more than 27 patients were seen per year. Assuming equal waiting times, individuals preferred the tele-endoscopy clinic to the mainland clinic. The net benefits were larger for tele-endoscopy clinics as long as the additional waiting time was not longer than four weeks. Tele-endoscopy clinics in Shetland are an efficient alternative to conventional practice. The results are sensitive to both economies of scale and scope. The model can readily be applied to mainland communities outside the main population centres in Scotland.

Pharmaceutical review using telemedicine - a before and after feasibility study

ons, 24/02/2010 - 23:33

Only 42 of the 116 public hospitals in Queensland employ qualified pharmacists to staff their pharmacies. We undertook a feasibility study to determine if pharmaceutical reviews, undertaken face-to-face by a visiting pharmacist, could be replicated using telemedicine. The study was conducted in two phases, with the same pharmacist coordinating the project from the main hospital to two rural hospitals, which relied on supply nurses for all their pharmaceutical services. All inpatients admitted between October 2006 and May 2007 were included in the study. In Phase I the pharmacist made weekly visits to both facilities, to perform face-to-face pharmaceutical reviews of the current inpatients. In Phase 2, all pharmaceutical reviews were performed remotely by the pharmacist by telephone or videoconference. In Phase 1, 186 pharmaceutical activities were performed (mean 3.9 per patient). Of these, 78 pharmacist-initiated changes were recommended and 47 (60%) were implemented. In Phase 2, a total of 296 activities were performed (mean 3.1 per patient) and of the 140 recommendations made by the remote pharmacist, 74 (53%) were accepted. Of the accepted recommendations, there were 11 major interventions (those with a potential to prevent harm to the patient) in Phase 1 and 32 in Phase 2. There were no significant differences in the pharmaceutical activity rates in the two phases. Telepharmacy therefore may be an effective method of providing pharmaceutical reviews for patients in rural inpatient facilities, without an on-site pharmacist.

Home-based speech treatment for Parkinson's disease delivered remotely: a case report

ons, 24/02/2010 - 23:33

We investigated the validity and feasibility of online delivery of the Lee Silverman Voice Treatment (LSVT) for the treatment of the speech disorder of a patient with idiopathic Parkinson's disease. The treatment was delivered in 16 sessions to the participant's home, 90 km from the speech language pathologist. A PC-based videoconferencing system was used, operating at 128 kbit/s over the public telecommunications network. The patient achieved substantial improvements in vocal sound pressure levels during sustained vowel phonation (6.13 dB), reading (12.28 dB) and conversational monologue (11.32 dB). There were improvements in the duration of sustained vowel phonation (4 s). Improvements were also perceived in the degree of breathiness and roughness in the voice, and in overall speech intelligibility in conversation. The patient was very satisfied with the audio and video quality of the conferencing, and with the online treatment overall. He reported a preference for online sessions for the future management of his condition, rather than face-to-face treatment. Remote LSVT delivery was found to be feasible and effective.

Evaluation of a web-based lifestyle coach designed to maintain a healthy bodyweight

ons, 20/01/2010 - 00:38

We evaluated a web-based intervention, the Healthy Weight Assistant (HWA), which was designed to help people with a healthy bodyweight, or those who are slightly overweight, to achieve and maintain a healthy weight. Four evaluation methods were used: (1) pre- and post-test questionnaires; (2) real time usability-tests; (3) log-file analysis; (4) qualitative analysis of forum posts, email messages and free-text responses in the questionnaires. A total of 703 respondents received access to the HWA. Six weeks after receiving access, 431 respondents completed a second questionnaire. The enthusiastic responses showed that many people were interested in using an interactive online application to support achieving and maintaining a healthy weight. The preliminary results suggest that improvements with respect to motivation may lead to large effects, yet require only small changes in the design of the HWA. Sending automatic tailored reminders may enhance motivation to keep using the application. Motivation to change behaviour may be enhanced by emphasizing goal setting and visualizing progress.

Patient use and compliance with medical advice delivered by a web-based triage system in primary care

ons, 20/01/2010 - 00:38

We studied a web-based triage system which was accessible to the general public in the Netherlands. In a retrospective analysis we investigated the type of complaints that were submitted and the kind of advice provided. Over a period of 15 months, 13,133 different people began using the web-based triage system and 3812 patients went right through the triage process to the end. The most frequent complaints were common cold symptoms, such as cough and a sore throat (22%), itch problems (13%), urinary complaints (12%), diarrhoea (10%), headache (8%) and lower back pain (8%). Most commonly, the system generated the advice to contact a doctor (85%) and in 15% of the cases the system provided fully automated, problem-tailored, self-care advice. A total of 192 patients participated in a prospective study and completed an online survey immediately after the delivery of advice. A follow-up questionnaire on actual compliance was completed by 35 patients. Among these, 20 (57%) had actually complied with the advice provided by the system. A regression analysis revealed that intention to comply was strongly related to actual compliance. In turn, intention to comply was strongly related to attitude towards the advice (P < 0.001). Web-based triage can contribute to a more efficient primary care system, because it facilitates the gatekeeper function.

The Digital Eczema Centre Utrecht

ons, 20/01/2010 - 00:38

The University Medical Centre Utrecht (UMC Utrecht) has developed an eczema portal that combines e-consulting, monitoring and self-management training by a dermatology nurse online for patients and parents of young children with atopic dermatitis (AD). Patient satisfaction with the portal was high. It could be extended to become a Digital Eczema Centre for multidisciplinary collaboration between health-care providers from different locations and the patient. Before starting the construction of the Digital Eczema Centre, the feasibility was examined by carrying out a business case analysis. The purposes, strength and weaknesses showed that the Digital Eczema Centre offered opportunities to improve care for patients with AD. The financial analysis resulted in a medium/best case scenario with a positive result of 50–240,000 over a period of five years. We expect that the Digital Eczema Centre will increase the accessibility and quality of care. The web-based patient record and the digital chain-of-care promote the involvement of patients, parents and multidisciplinary teams as well as the continuity and coordination of care.

A study of a Dutch online decision aid for parents of children with ADHD

ons, 20/01/2010 - 00:38

During a three-month study period, visitors to an online decision aid (DA) for attention deficit hyperactivity disorder (ADHD) were invited to complete an online questionnaire before and after working through the DA. Some 75,000 unique visitors found their way to the page on DAs, although fewer than 1 in 10 visited the DA for ADHD, staying there for about six minutes on average and using 8–9 clicks to navigate. A total of 195 people completed the first questionnaire (a response rate of about 3%). Only 12 of the respondents to the first questionnaire (6%) completed the second questionnaire. There was no significant effect of the DA as measured by three decisional outcome measures. Respondents moderately appreciated the information received. Even though the DA was constructed according to evidence-based guidelines and International Patient Decision Aids Standards wherein expert and patient involvement are assured, these preliminary results suggest that the online DA for ADHD needs further work to support the decision-making process of parents with regard to the most appropriate treatment for their child.

User acceptance of an Internet training aid for migraine self-management

ons, 20/01/2010 - 00:38

We have developed an Internet training aid (MyMigraine) for migraine self-management derived from an evidence-based protocol for behavioural attack prevention. Its acceptance was tested in two studies concerning the opinions of new patients (n = 10), and the opinions of expert patients acquainted with the protocol (n = 6). The questionnaires employed 5-point scales. In study 1, all lessons were rated positively regarding clarity, instructiveness, importance and easy execution. After training, the patients were positive about user-friendliness and clarity (mean score 3.9), training content (3.5), satisfaction (3.6) and benefits (attack risk detection: 3.7; preventive coping: 3.9). In study 2, the expert patients provided positive ratings for the web application (mean score 4.1), digital support (3.8–4.4) and web adaptation of the protocol (4.1–4.8). The expert patients considered MyMigraine instructive, captivating and fun to work with, but emphasized the necessity of patient-to-patient contact. The training aid was very well accepted by new and experienced patients with chronic migraine.

Use of web services for computerized medical decision support, including infection control and antibiotic management, in the intensive care unit

ons, 20/01/2010 - 00:38

The increasing complexity of procedures in the intensive care unit (ICU) requires complex software services, to reduce improper use of antibiotics and inappropriate therapies, and to offer earlier and more accurate detection of infections and antibiotic resistance. We investigated whether web-based software can facilitate the computerization of complex medical processes in the ICU. The COSARA application contains the following modules: Infection overview, Thorax, Microbiology, Antibiotic therapy overview, Admission cause with comorbidity and admission diagnosis, Infection linking and registration, and Feedback. After the implementation and test phase, the COSARA software was installed on a physician's office PC and then on the bedside PCs of the patients. Initial evaluation indicated that the services had been integrated easily into the daily clinical workflow of the medical staff. The use of a service oriented architecture with web service technology for the development of advanced decision support in the ICU offers several advantages over classical software design approaches.

Patient-initiated online support groups: motives for initiation, extent of success and success factors

ons, 20/01/2010 - 00:38

We studied the success and success factors of online support groups (OSGs) for patients, and the motives and goals of people who start such groups. We interviewed 23 webmasters of OSGs for patients with breast cancer, fibromyalgia and arthritis. The majority were women (n = 20) and most were patients (n = 21). Analysis of the interviews revealed that webmasters had altruistic and intrinsic motives for initiating an online support group. They defined success as the fulfilment of the goals they had in mind when they initiated their groups. To be able to make a group successful, decisions about its organization and management need to be coherent with these goals. Most webmasters stressed that promoting the group, keeping it alive and moderating the messages were vital success factors during the evolution stage. Management of the OSGs took up much of the webmasters' time and energy. On average webmasters were occupied with the group for 10–15 hours a week. Our study provides an overview of the pros and cons of differing decisions that have to be made when initiating an OSG.

Adding value to figures: a web-based European public health information system

ons, 20/01/2010 - 00:38

In 2008 a prototype, web-based system was launched which provided information for different user groups interested in European public health topics. The EUPHIX system contained scientifically sound data, with presentations as well as textual information. The information was structured according to the European Community Health Indicators (ECHI) shortlist. The information included different types of data presentations (tables, interactive graphs and maps), explanatory texts and overviews of the data sources and the literature used. The content was produced by a network of European experts according to a structured, peer-reviewed editorial process. Thus EUPHIX provided an easily accessible, comprehensive, state-of-the-art information source. To ensure that it will continue, financial support will be needed. Co-ownership by the European Commission and the Member States seems an appropriate solution.
