Penny A. Jennett; L. Affleck Hall; David Hailey; Arto Ohinmaa; C. Anderson; Roger E. Thomas; B. Young; Diane L. Lorenzetti; Richard E. Scott

We reviewed the socio-economic impact of telehealth, focusing on nine main areas: paediatrics, geriatrics, First Nations (i.e. indigenous peoples), home care, mental health, radiology, renal dialysis, rural/remote health services and rehabilitation. A systematic search led to the identification of 4646 citations or abstracts; from these, 306 sources were analysed. A central finding was that telehealth studies to date have not used socioeconomic indicators consistently. However, specific telehealth applications have been shown to offer significant socio-economic benefit, to patients and families, health-care providers and the health-care system. The main benefits identified were: increased access to health services, cost-effectiveness, enhanced educational opportunities, improved health outcomes, better quality of care, better quality of life and enhanced social support. Although the review found a number of areas of socio-economic benefit, there is the continuing problem of limited generalizability.

Study quality and evidence of benefit in recent assessments of telemedicine

David Hailey; Arto Ohinmaa; Risto Roine

We carried out a systematic review of recent telemedicine assessments to identify scientifically credible studies that included comparison with a non-telemedicine alternative and that reported administrative changes, patient outcomes or the results of an economic assessment. From 605 publications identified in the literature search, 44 papers met the selection criteria and were included in the review. Four other publications were identified through references cited in one of the retrieved papers and from a separate project to give a total of 48 papers for consideration, which referred to 42 telemedicine programmes and 46 studies. Some kind of economic analysis was included in 25 (52%) of the papers. In considering the studies, we used a quality appraisal approach that took account of both study design and study performance. For those studies that included an economic analysis, a further quality-scoring approach was applied to indicate how well the economic aspects had been addressed. Twenty-four of the studies were judged to be of high or good quality and 11 of fair to good quality but with some limitations. Seven studies were regarded as having limited validity and a further four as being unacceptable for decision makers. New evidence on the efficacy and effectiveness of telemedicine was given by studies on geriatric care, intensive care and some of those on home care. For a number of other applications, reports of clinical or economic benefits essentially confirmed previous findings. Although further useful clinical and economic outcomes data have been obtained for some telemedicine applications, good-quality studies are still scarce.

The Effectiveness of Telemental Health Applications : A Review

David Hailey; Risto Roine; Arto Ohinmaa

Objective: To review the evidence of benefit from use of telemental health (TMH) in studies that reported clinical or administrative outcomes. Method: Relevant publications were identified through computerized literature searches using several electronic databases. Included for review were scientifically valid articles that described controlled studies, comparing TMH with a non-TMH alternative, and uncontrolled studies that had no fewer than 20 participants. Quality of the evidence was assessed with an approach that considers both study performance and study design. Judgments were made on whether further data were needed to establish each TMH application as suitable for routine clinical use. Results: Included in the review were 72 papers that described 65 clinical studies; 32 (49%) studies were of high or good quality. Quality of evidence was higher for Internet- and telephone-based interventions than for video conferencing approaches. There was evidence of success with TMH in the areas of child psychiatry, depression, dementia, schizophrenia, suicide prevention, posttraumatic stress, panic disorders, substance abuse, eating disorders, and smoking prevention. Evidence of success for general TMH programs and in the management of obsessive–compulsive disorder were less convincing. Further study was judged to be necessary or desirable in 53 (82%) of the studies. Conclusion: Evidence of benefit from TMH applications is encouraging, though still limited. There is a need for more good-quality studies on the use of TMH in routine care. The emerging use of Internet-based applications is an important development that deserves further evaluation.

ObjectivesWe assessed health-related quality of life (HRQOL), its associated factors, and examined measurement properties of the EuroQol - 5 Dimensions - 5 Levels (EQ-5D-5L) in HIV/AIDS patients.MethodsA cross-sectional multi-site survey was conducted in 1016 patients (age: 35.4 ± 7.0 years; 63.8% male) in three epicenters of Vietnam. Internal consistency reliability, convergent validity, and discriminative validity of the EQ-5D-5L and a visual analogue scale (VAS) were evaluated. Tobit censored regression models were used to identify predictors of HRQOL in HIV/AIDS patients.ResultsThe mean EQ-5D-5L single index and VAS were 0.65 (95% Confidence Interval (CI) = 0.63; 0.67) and 70.3 (95% CI = 69.2; 71.5). Cronbach’s alpha of five dimensions was 0.85. EQ-5D-5L has a good convergent validity with VAS (0.73). It discriminated patients at different HIV/AIDS stages, duration of ART, and CD4 cell count. Predictors of poorer HRQOL included being female, lower education level, unemployment, alcohol and drug use, CD4<200 cells/mL, and advanced HIV/AIDS stages.ConclusionThe EQ-5D-5L has good measurement properties in HIV/AIDS patients and holds potentials for monitoring ART outcomes. Integration of HRQOL measurement using EQ-5D-5L in HIV/AIDS clinical practice could be helpful for economic evaluation of HIV/AIDS interventions.

Some of the first telepsychiatry experiments in Finland were carried out at the Department of Psychiatry of the University of Oulu, where videoconferencing has been used for family therapy, occupational counselling, consultation and teaching. In 1996 videoconferencing was used for a total of 249 hours, which increased to 434 hours in 1997. During 1997, 45 of the time was used for teaching, 26 for occupational counselling, consultations and therapies, 23 for training and 6 for administration mainly testing the connections . In a survey, 37 participants rated aspects of the quality of the videoconferences on a scale from 4 poor to 10 excellent . The audio quality had a mean value of 8.0 SD0.9 , the picture quality 7.5 SD1.5 , and the general value of the videoconference was rated 7.5 SD1.0 . Preliminary results with telepsychiatry in Finland have been promising. Interactive videoconferencing provides an easy, fast and relatively inexpensive method of providing psychiatric services over long distances.

Evidence of benefit from telerehabilitation in routine care: a systematic review

David Hailey; Risto Roine; Arto Ohinmaa; Liz Dennett

We systematically reviewed the evidence on the effectiveness of telerehabilitation (TR) applications. The review included reports on rehabilitation for any disability, other than mental health conditions, and drug or alcohol addiction. All forms of telecommunications technology for TR and all types of study design were considered. Study quality was assessed using an approach that considered both study performance and study design. Judgements were made on whether each TR application had been successful, whether reported outcomes were clinically significant, and whether further data were needed to establish the application as suitable for routine use. Sixty-one scientifically credible studies that reported patient outcomes or administrative changes were identified through computerized literature searches on five databases. Twelve clinical categories were covered by the studies. Those dealing with cardiac or neurological rehabilitation were the most numerous. Thirty-one of the studies (51%) were of high or good quality. Study results showed that 71% of the TR applications were successful, 18% were unsuccessful and for 11% the status was unclear. The reported outcomes for 51% of the applications appeared to be clinically significant. Poorer-quality studies tended to have worse outcomes than those from high- or good-quality studies. We judged that further study was required for 62% of the TR applications and desirable for 23%. TR shows promise in many fields, but compelling evidence of benefit and of impact on routine rehabilitation programmes is still limited. There is a need for more detailed, better-quality studies and for studies on the use of TR in routine care.

Abstract Health-related quality of life (HRQL) is a good indicator to monitor and evaluate healthcare services for adults with HIV/AIDS. This study described HRQL of adults with HIV and its determinants, and compared it with HRQL for the general population. A cross-sectional study with a national multistage sampling of households with and without HIV-positive people was conducted in 2008. Six provinces were purposively selected to represent areas of the country and progressions of HIV epidemics. Households were sampled with probability-proportional-to-size, following the selection of rural and urban districts. A total of 820 HIV-positive and HIV-negative adults (mean age: 32.5; 38.7% female) were interviewed. Among 400 HIV-positive people, 52.3% had a history of injecting drugs, and 56.3% were at AIDS stage and receiving antiretroviral treatment (ART). HRQL was measured using the EuroQOL five-dimension questionnaire (EQ-5D). Multiple regression models were purposefully constructed to examine the determinants of HRQL. The EQ-5D index and visual analog scale (VAS) score in less advanced HIV people (0.90, 69.3) and AIDS patients (0.88, 65.2) were significantly lower than those of the general population (0.96, 81.6) (p<0.001). The frequency of reported problems across EQ-5D dimensions in the HIV population (2.4–30.9%) was significantly higher than in the general population (0.7–12.1%). Compared to ART patients, those at earlier HIV stages reported having problems at similar proportions across four HRQL dimensions, except pain/discomfort, where ART patients had a significantly higher proportion. Injecting drug users taking ART perceived lower HRQL score than non-injecting drug users. Multiple regression determined that joblessness (p<0.01) and inaccessibility to health services (p<0.05) were associated with lower HRQL. In addition, involvements in self-help groups significantly improved HRQL among HIV-positive participants (p<0.05). The findings highlight the need to improve the health service referral system and enhance psychological and social supports for patients in early stages of HIV infection in Vietnam.

Drug use negatively affects adherence to and outcomes of antiretroviral treatment (ART). This study evaluated the cost-effectiveness of integrating methadone maintenance treatment (MMT) with ART for HIV-positive drug users (DUs) in Vietnam. A decision analytical model was developed to compare the costs and consequences of 3 HIV/AIDS treatment strategies for DUs: (1) only ART, (2) providing ART and MMT in separated sites (ART-MMT), and (3) integrating ART and MMT with direct administration (DAART-MMT). The model was parameterized using empirical data of costs and outcomes extracted from the MMT and ART cohort studies in Vietnam, and international published sources. Probabilistic sensitivity analysis was conducted to examine the models robustness. The base-case analysis showed that the cost-effectiveness ratio of ART, DAART-MMT, and ART-MMT strategies was USD 1358.9, 1118.0 and 1327.1 per 1 Quality-Adjusted Life Year (QALY), equivalent to 1.22, 1.00, and 1.19 times Gross Domestic Product per capita (GDPpc). The incremental cost-effectiveness ratio for DAART-MMT and ART-MMT versus ART strategy was 569.4 and 1227.8, approximately 0.51 and 1.10 times GDPpc/QALY. At the willingness to pay threshold of 3 times GDPpc, the probability of being cost-effective of DAART-MMT versus ART was 86.1%. These findings indicated that providing MMT along with ART for HIV-positive DUs is a cost-effective intervention in Vietnam. Integrating MMT and ART services could facilitate the use of directly observed therapy that supports treatment adherence and brings about clinically important improvements in health outcomes. This approach is also incrementally cost-effective in this large injection-driven HIV epidemic.

BACKGROUND Along with a dramatic rise in the rates of childhood obesity, obesity-related disorders, such as type 2 diabetes, hypertension, and obstructive sleep apnea, are seen with increasing frequency in children. As a consequence, overweight and obese children may use health care services more often than their normal weight peers. The aim of the current study was to assess health service use and costs across categories of weight status. METHODS Prospective cohort study using data from a population-based survey among grade 5 children in the Canadian province of Nova Scotia linked with administrative health data, using a combination of deterministic and probabalistic matching (n = 4 380). Total health care costs (physician and hospital costs), lifetime (up to age 14 years) physician costs and number of physician visits were assessed in a series of multiple regression models. RESULTS There was a gradient for higher costs and utilization across the three weight groups. Total health care costs in the three years following the survey were 21% (95% CI: 2-43) higher in obese children compared with normal weight children. Obese children also had significantly higher lifetime physician costs and more physician visits than their normal weight peers. The health care cost trajectories of normal weight and obese children drift apart as early as 3 years of age. Interpretation. Obese children in the Canadian province of Nova Scotia have significantly higher health care costs and more physician visits and specialist referrals than their normal weight peers, highlighting the need for cost-effectiveness studies of obesity prevention programs.
