F<strong>in</strong>ally, <strong>in</strong> the RCT by Cheng et al 212 (n = 460 and with 3-year follow-up), the <strong>in</strong>tegrated<br />

<strong>in</strong>tervention was assessed with sheltered hous<strong>in</strong>g at a medical care centre <strong>for</strong> “homeless” veterans<br />

with SMI and/or substance abuse (not specify<strong>in</strong>g percentage of psychiatric diagnoses of substance<br />

abuse of the sample).<br />

In some of the studies assessed, the <strong>in</strong>tervention of the control group exceeds what <strong>in</strong> our<br />

context would be standard treatment, which would favour the lack of appearance of differences<br />

between the <strong>in</strong>terventions compared. An absence of data from quality studies has also been encountered,<br />

show<strong>in</strong>g that <strong>in</strong>tegrated treatments are more effective than non-<strong>in</strong>tegrated treatments,<br />

although both <strong>in</strong>terventions show efficacy compared with the standard treatment <strong>for</strong> dual SMI<br />

patients.<br />

Another relevant aspect is that these scientific studies orig<strong>in</strong>ate exclusively from Anglo-<br />

Saxon countries and generate doubts about the extrapolation to our context, as <strong>in</strong> our context there<br />

are no <strong>in</strong>tegrated assertive community treatment teams/programmes <strong>for</strong> dual pathology; although<br />

there are <strong>in</strong>tegrated treatment teams.<br />

In our context there are few services with <strong>in</strong>tegrated treatment programmes <strong>for</strong> dual patients<br />

and start<strong>in</strong>g them up systematically and <strong>in</strong> a generalised way would represent an <strong>in</strong>crease<br />

<strong>in</strong> resources, when <strong>in</strong> many fields there are parallel networks with programmes that are already<br />

function<strong>in</strong>g.<br />

The motivation factor is important <strong>in</strong> these studies and differences are observed with respect<br />

to the moment of the <strong>in</strong>tervention. There are authors that suggest that the heterogeneity could be<br />

reduced, study<strong>in</strong>g <strong>in</strong>terventions and results related to specific treatment stages (support and skills<br />

development both <strong>for</strong> handl<strong>in</strong>g and <strong>for</strong> prevent<strong>in</strong>g relapses) 213<br />

People with SMI and substance abuse<br />

No differences were found between long-term <strong>in</strong>tegrated treatment (36<br />

months) and standard treatment (which <strong>in</strong>cludes the same <strong>in</strong>terventions except<br />

<strong>for</strong> assertive community treatment, which were developed by different<br />

teams) respect to the use of substances (n = 85; 1 RCT; RR = 0.89; 95% CI:<br />

between 0.6 and 1.3) 52 .<br />

With reference to abandon<strong>in</strong>g the treatment it is also observed that no<br />

differences have been found, either, between the long-term <strong>in</strong>tegrated treatment<br />

(36 months) and standard treatment (n = 603; 3 RCT; RR = 1.09; 95%<br />

IC: between 0.8 and 1.5) 52 and the same occurs with respect to the number<br />

of rehospitalisations (n = 198; 2 RCT; RR = 0.88; 95% CI: between 0.6 and<br />

1.2) 52 .<br />

Regard<strong>in</strong>g to <strong>in</strong>tegrated assertive community treatment (ACT) and<br />

standard ACT, no significant results were observed <strong>in</strong> favour of either the<br />

<strong>in</strong>terventions regard<strong>in</strong>g satisfaction at 24 months, although there are significant<br />

results between both <strong>in</strong>terventions when compared with standard<br />

treatment (p = 0.03) 211 . No differences have been found, either with respect<br />

to hous<strong>in</strong>g stability at 24 months although they do exist between both <strong>in</strong>terventions<br />

when compared with standard treatment (p = 0.03) 211 .<br />
