A study of Korean women showed positive results. Using
a full case analysis, statistically significant (p = 0.001)
higher rates of completion of diagnostic follow-up after
breast cancer screenings were reported in the CHW intervention
arm compared to the usual care arm [20]. An
intention-to-treat analysis showed a trend towards significance
(p = 0.069) for the difference in the completion of
diagnostic follow-up, favouring the CHW intervention
arm. An ER of 1.00 was found.
A study of primarily Hispanic women also showed positive
results. Statistically significant (p = 0.005) higher rates
of endoscopy appointments at three months were found
in the CHW intervention arm compared to the usual care
arm [21]. Significantly (p = 0.019) higher rates were
also found for the completion of endoscopy at six
months. A trend towards significance (p = 0.086) was
found for completing faecal occult blood tests (FOBT)
after three months: a greater proportion of women in
the CHW intervention arm completed the FOBT. No
statistically significant differences in the completion of
endoscopy at three months were found. The ER for this
study was 0.75.
A third study with Hispanic women did not show statistically
significant differences in the number of women
returning for a second annual preventive exam compared
to women receiving only postcard reminders [22].
Consequently, the ER was 0.00.
The mean ER for the outcome category “access to
care” was 0.58.
