Telehealth can reduce Deaths and Emergency Hospital care

Telehealth Can Reduce Deaths and Emergency Hospital Care


Tuesday, 03 July 2012





For people with long term conditions, telehealth can reduce deaths and help patients avoid the need for emergency hospital care, finds a study published on However, the estimated scale of hospital cost savings is modest and may not be sufficient to offset the cost of the technology, say the authors.

Telehealth uses technology to help people with health problems live more independently at home. For example, equipment to measure blood pressure or blood glucose levels at home can reduce hospital visits. Measurements are electronically transmitted to a health professional.

Several studies have been conducted on the impact of telehealth for people with long term conditions, but findings have been mixed. Some research suggests that telehealth can help patients develop a better understanding of their condition, leading to better quality and more appropriate care, as well as more efficient use of health care resources, but other studies have found negative effects.

However, assessing the scale of such an effect is complex.

So, an international team, led by researchers at the Nuffield Trust, set out to assess the impact of telehealth on hospital use for 3,230 patients with long term conditions (diabetes, chronic obstructive pulmonary disease or heart failure) over one year.

The study is one of the largest telehealth studies ever conducted.

Patients were randomly split into two groups. A total of 1,570 intervention patients were given devices and taught how to monitor their condition at home and transmit the data to health care professionals. A further 1,584 control patients received usual care.

During the study period, significantly fewer (43%) of intervention patients were admitted to hospital compared with 48% of control patients. Significantly fewer (4.6%) of intervention patients died compared with 8.3% of controls. This equates to about 60 lives over a 12 month period.

There were also statistically significant differences in the mean number of emergency hospital admissions per head (0.54 for intervention patients compared with 0.68 for controls) and the mean hospital stay per head (4.87 days for intervention patients compared with 5.68 days for controls), although the authors say these findings should be interpreted with caution.

These differences remained significant after adjusting for several factors that could have influenced the results. However, the authors point out that these effects appear to be linked with short term increases in hospital use among control patients, the reasons for which are not clear.

They also say that the estimated cost savings are modest.

These results suggest that telehealth reduced mortality and helped patients avoid the need for emergency hospital care, conclude the authors. This may be because telehealth helps patients better manage their conditions and avoid a worsening of symptoms that may need emergency care. Other possibilities are that telehealth changes people’s perception of when they need to seek additional support.

But they stress that these benefits need to be balanced against the cost of the technology itself and the level of savings that can be achieved.

In an accompanying editorial, Josip Car, Director of the Global eHealth Unit at Imperial College London and colleagues say this latest evidence doesn’t warrant full scale roll-out but more careful exploration.

Although factors that might be important for successful telehealth can be described, “we need more clarity on how to interpret the relative contributions of these elements,” they write.

They suggest that policy makers, commissioners, and guideline developers should help ensure that the research agenda focuses on areas where telehealth shows most promise. “There is great potential but also still much to be done,” they conclude.

Although results shall be taken carefully, there is always a benefit having care at home, patients are at home with their relatives, they are inside their normal environment, known atmosphere. They take an active role using tele health and this is always better than a passive role. So if the results show a positive trend and the benefits for patients staying at home are also clear, value proposals for home care services shall be taken seriously for the patients themselves.
It is not only cost saving for public health services what matters, it is also the patient perception of his or her own personal well being. Cost saving is not only the point, it is also how much worth it is to stay at home; depending on type of patients, home care is not so expensive. The key is based on the service model and organization, and probably this is what will need a deep redefinition.
Discussion about the cost of technology is the easy way to look into the other side of the problem, the real disruption is how to create a service model that is efficient and really gets people staying at home and going to emergency services and hospital when it is need.

¿ Quins són els avantatges de la telemonitorització ?

Quan parlem de telemonitorització a l’entorn de la salut, o bé de les tecnologies de la informació TIC a la salut (en termes anglosaxons eHealth), sempre ens queda el dubte de si primer s’han desenvolupat unes tecnologies “màgiques” i després hem de trobar “quin problema” ressolen o és a l’inrevés. Probablement avui hi ha una convergència, d’una banda les tecnologies han evolucionat assolint uns nivells que poden donar solucions tècniques de costos raonables al món sanitari, de l’altra banda estem en una reinvenció del sistema sanitari, que algú podria anomenar una autèntica revolució ja que el sistema actual no podrà pagar els costos si no esdevé més eficient i canviem el model de serveis.

És significatiu veure el volum de noves empreses i inversions relacionades amb la salut, i concretament en telemonitorització. Continua llegint

Què és la Carpeta Personal de Salut?

Estructura de la CPSLa Carpeta Personal de Salut (CPS) pretèn ser el lloc on tots puguem consultar les nostres dades d’història clínica generades en accedir als centres públics i concertats del Departament de Salut. El seu accés és protegit, jo diria extremadament protegit, i només si pot accedir si es disposa del certificat digital, o bé IdCAT o bé el DNIe . Tots dos mètodes requereixen anar personalment a validar la contrasenya personal, en el cas del DNIe, que és el que utilitzo jo, cal anar a una dependència de la Policia Nacional … tot plegat molt complicat.

Cal tenir un lector USB del DNI electrònic i instal.lar uns certificats digitals a l’ordinador. Difícil per usuaris no experts i, fins it tot si ets un usuari avançat costa molt de seguir el procés. Continua llegint

Can patients improve their own health ? Results from a study of smartphone use in diabetes and hypertension

Can patients improve their own health ? Results from a study of smartphone use in diabetes and hypertension.

It is clear, being at home is always the best. Nevertheless is it cost efficient ? What about people with chronic disease ? As usual there is a chicken and egg circle, until technology is deployed to big amounts of patients, the costs will not be low. If we assume that public healthcare systems need to decrease costs as the public system is not more sustainable (or dramatically over budget), the only chance is going for some remote patient monitoring systems that combine good professional health care at home but being effective based on the remote eHealth monitoring systems.

In general people is not ready for health technology, and health technology and their devices and systems, are not enough user friendly. Think about the elders, the segment of population above 60, far away from being tech-lovers or even worst tech users, and demanding always more face to face attention. The key will be the right combination between direct care services and the use of eHealth systems. One of the hopes is that new generations, and in fact the sons and daughters of current elders, are either digital natives or digital immigrants, they may adopt faster some good eHealth solutions, if they can bring a better quality of life to their parents. Early adopters will not be the patients but the relatives and care givers of the patients. This is the challenge.
