Results from RCTs and controlled studies

Study ID Outcome Main results at follow up
(+) = positive effect, (-) = negative effect, (0) = no significant effect
Crotty 2004
RCT
Appropriate prescribing (medication appropriateness index) Follow up at 3 months (NB - two control groups - one external and one within the facility (results presented for external control grp only))
Change MAI score (+) Mean score (95% CI)Intervention 4.10 (2.11-6.10), Control 0.41 (-0.42-1.23), Difference p = 0.004
Nursing home behaviour problem Change NHBPS (0), Mean score (95% CI)Intervention 3.9 (-2.7-10.5), Control 1.2 (-9.1-11.6), P = 0.440
Mortality Mortality (0)
No differences between groups (p = 0.304)

Goodman 2007 (non randomised controlled study) Bowel related problems Follow up at 6 months
Normal bowel patterns (+)
Intervention - significant increase in normal bowel patters, control grp - little change
Medication and continence related product use Prescription of laxatives (0)
Increase in both groups but no statistically significant differences between groups p = 0.159
Dependency (Barthel index) Dependency (+) Mean change score p = 0.002
Intervention -0.02 (SD 3.1), Control -1.84 (SD 3.7)
Bowel related hospital admission 1 admission in intervention grp, none in control (n = 120)

King 2001 (non randomised controlled study) Follow up at 1 month. Data collected on 184 residents (75 reviewed, 109 not reviewed).
Medication prescribed Changes in medication prescribed - mean (SD) (0)
Intervention -0.35 (2.56), Control -0.03 (1.90) P = 0.37
Medication administered Changes in medication administered - mean (SD) (0)
Intervention -0.44 (2.45), Control 0.12 (1.84), P = 0.16
Weekly Cost ($) - authors say study underpowered for this outcome Weekly cost (0)
Intervention -0.29 (10.80), Control 0.43 (12.16), P = 0.75
Mortality (adjusted for length of time in home) Mortality (0)
Adjusted mortality data showed 6% of reviewed residents died compared to 15% of those not reviewed p = 0.07

Kane 2004 (controlled study) - evaluating EverCare Follow up at 18 months
2 control groups
a) other residents in same homes not enrolled in Evercare
b) residents in homes in same geographical area that did not participate n Evercare
Assessments at 6,12, 18 months (within 30 days)
Mortality Mortality
Evercare rate significantly less than for control-in group but was slightly higher than control-out group (non significant)
Preventable hospitalizations Rates of preventable admissions lower in Evercare than for either control but only significant when compared to control-out.
No differences in hospitalization rates overall. (0)
Functional change No significant differences in ADLs between Evercare and either control. (0)

Unadjusted MD (0)
-0.76 (-2.09, 0.57)

Opie 2002
RCT (poor study design)
Frequency & severity of disruptive behaviours (Behaviour Assessment Graphical System and counts of certain behaviours) Follow up at one month

ANOVA revealed no statistically significant changes
BAGS scores (0)
No significant between group differences
Assessment of change by senior nursing home staff - rated on 4 point scale(interviewed one month after completion of trial) Assessment by staff
No data reported on between group differences.
Staff reported that the frequency of target behaviours had decreased in at least one behavioural category for 75% residents and that severity had decreased in at least one category for 60%.
