Authors’ Corrigendum
The authors of “A Remote Medication Monitoring System for Chronic Heart Failure Patients
to Reduce Readmissions: A Two-Arm Randomized Pilot Study” (JMIR 2016;18(4):e91) have
made the following changes to the text, tables, references, and supplemental files.
These changes reflect replacing the Morisky Medication Adherence Scale with the Medical
Outcomes Study adherence measure. As the outcomes from the two measures are similar,
this change will not substantially impact the interpretation of the findings and conclusions
for this study.
In the “Data Collection and Outcome Measures” subsection of the Methods:
In the second paragraph, the sentence “Medication adherence was assessed using two
self-reported measures” has been changed to “Medication adherence was assessed using
a self-reported measure and data collected by the device.”
In the second paragraph, the sentence “The 8-item Morisky Medication Adherence Scale
(MMAS) is a valid and reliable instrument that is scored from 0 to 8 to yield three
categories of adherence: 0=high adherence, 1-2=medium adherence, and ≥3=low adherence
[43]” has been removed. Because the only in-text mention of reference 43 has been
removed, all subsequent references have been renumbered in the text and reference
list accordingly.
In the second paragraph, the sentence “The second measure was a single question from
the Medical Outcomes Study (MOS) [44,45]” has been changed to “Self-reported adherence
was assessed using a single question from the Medical Outcomes Study (MOS) [43,44].”
In the “Baseline Characteristics” subsection of the Results:
In the first paragraph, the sentence “Medication adherence was low (MMAS ≥3) for 27%
(6/22) and medium to high (MMAS 0-2) for 73% (16/22)” has been changed to “Seventy-two
percent (18/25) of participants were categorized as ‘adherent’ based on self-reported
adherence.”
In Table 1:
Under Sociodemographics, on the line “Age (years), mean (SD)”, the superscripted “a”
has been removed.
Under Medication Adherence, the Morisky MMAS-8 scale and corresponding subrows have
been removed.
On the line “Health-related quality of life (MLHFQ), mean (SD)
b”, the superscripted “b” has been changed to “a”.
The original footnote “a” (“The MMAS is scored so that higher values indicate low
adherence”) has been removed, and the original footnote “b” (“The MLHFQ is scored
so that higher values indicate an adverse impact on quality of life”) has been relabeled
“a”.
In the “Medication Adherence” subsection of the Results:
In the first paragraph, the sentence “Assessed using the MMAS, 75% (9/12) of the control
group and 60% (6/10) of the intervention group were categorized as adherent (MMAS
score=0-2)” has been removed.
In Table 4:
Under Medication Adherence, the Morisky MMAS-8 scale and corresponding subrows have
been removed.
On the line “MOS-Adhere (adherent), n (%)”, “8 (62)” has been changed to “9 (69)”,
and “.56” has been changed to “.61”.
On the line “Health-related quality of life (MLHFQ), mean (SD)
c”, the superscripted “c” has been changed to “b”.
The original footnote “b” (“The MMAS is scored so that higher values indicate low
adherence”) has been removed, and the original footnote “c” (“The MLHFQ is scored
so that higher values indicate an adverse impact on quality of life”) has been relabeled
“b”.
In the Discussion section, the sentence, “However, based on data from our primary
method of assessing change in medication adherence (self-reported MMAS), the intervention
did not appear to improve medication adherence” has been changed to “However, the
intervention did not improve medication adherence as measured by self-report (ie,
MOS).”
“MMAS: Morisky Medication Adherence Scale” has been removed from the Abbreviations
list.
Multimedia Appendix 1 “Enrollment and Closeout Questionnaires” has been replaced with
the new version.
The correction will appear in the online version of the paper on the JMIR website
on February 5, 2019, together with the publication of this correction notice. Because
this was made after submission to PubMed, PubMed Central, and other full-text repositories,
the corrected article also has been resubmitted to those repositories.
Editorial Notice
Authors and journal had to publish this correction due to legal threats by Steven
Trubow and Donald Morisky from the company MMAS Research LLC, the copyright holder
of the instrument. This is unfortunately not an isolated case, as the developers of
this scale are known to comb the literature and ask those who used the scale for research
to pay for a retroactive license which may cost thousands or tens of thousands of
dollars, and to add references to their work [1]. This is now the third correction
JMIR has to publish related to studies using the MMAS instrument.
The Committee on Publication Ethics (COPE) has recently discussed the ethics of this
type of behavior by copyright holders of scales (“holding authors to ransom in this
way”) and recommends to emphasize “the fact that this is not good for the advancement
of scientific knowledge or in the public interest” [2]. As open access and open science
publisher we remind our authors of our policies and preference for public and free
availability of research tools, including questionnaires [3]. We actively discourage
use of instruments which are not available under a Creative Commons Attribution license,
and encourage our authors to use or develop/validate new instruments. We continue
with our special call for papers for short paper instruments or electronic tools licensed
under Creative Commons or available under an Open Source license that can be used
as a free alternative to measure medication adherence, and will waive the article
submission fee for such development and validation papers.
