Background Communication is key to understanding the
emotional state of critical care patients.
Objective To analyze the effectiveness of the communi-
cative intervention known as CONECTEM, which incorpo-
rates basic communication skills and augmentative
alternative communication, in improving pain, anxiety,
and posttraumatic stress dis symptoms in critical
care patients transported by ambulance.
Methods This study had a quasi-experimental design with
intervention and control groups. It was carried out at 4
emergency medical centers in northern Spain. One of the
centers served as the intervention unit, with the other 3
serving as control units. The nurses at the intervention cen-
ter underwent training in CONECTEM. Pretest and posttest
measurements were obtained using a visual analog scale to
measure pain, the short-version State-Trait Anxiety Inven-
tory to measure anxiety, and the Impact of Event Scale to
measure posttraumatic stress dis symptoms.
Results In the comparative pretest-posttest analysis of
the groups, significant differences were found in favor of
the intervention group (Pillai multivariate, F
2,110
= 57.973,
P < .001). The intervention was associated with improve-
ments in pain (mean visual analog scale score, 3.3 pre-
test vs 1.1 posttest; P < .001) and posttraumatic stress
dis symptoms (mean Impact of Event Scale score,
17.8 pretest vs 11.2 posttest; P < .001). Moreover, the per-
centage of patients whose anxiety improved was higher
in the intervention group than in the control group (62%
vs 4%, P < .001).
Conclusion The communicative intervention CONECTEM
was effective in improving psychoemotional state among
critical care patients during medical transport. (American

ffective communication is key to understanding the difficulties implicit in critical ill-
ness.1,2 Critically ill patients often experience psychoemotional symptoms such as
sadness, anger, nervousness, worry, fear, stress, anxiety, and pain,3-5 which are related to
their inability to communicate.6,7 In addition, the reduced level of awareness of these
patients can lead to states of confusion or delirium,8,9 which alter their perceptions
of reality.10 The negative feelings contribute to the frustration generated by the lack of commu-
nication and can affect the patient’s perception of the quality of nursing care received.1,2,11 The
most prevalent negative psychoemotional states among critically ill patients are pain (experi-
enced by 70%-89% of patients),12,13 anxiety (30%-60%), and posttraumatic stress (27%).3,14-16
Research on in-ambulance communication
between critical care patients and nurses first emerged
in Europe.17-19 In the United States, effective commu-
nication has been a quality standard for the treatment
of critical care patients for several years.20 An increas-
ing amount of research on the topic has been per-
formed in Spain.21
Inadequate communication due to physical,
cognitive, and psychological barriers is one of the
main problems affecting critical care patients.10,22,23
Misunderstandings and/or misinterpretations gen-
erate insecurity and frustration among nurses and
reduce their effectiveness in treating pain, providing
emotional support, and meeting patients’ needs.24,25
Research on patient-nurse communication should
involve measurement of pain as well as psychoemo-
tional variables such as anxiety and the effects of
trauma, which can lead to symptoms of posttraumatic
stress dis (PTSD) in critically ill patients.26
Patak et al27 and Happ et al28 were among the
first authors to propose a set of communicative inter-
ventions based on augmentative alternative commu-
nication (AAC) and basic communication skills (BCS)
for use with critical care patients. These recommenda-
tions led to the development of various AAC mod-
els.29,30 Nurses received training based on these
models,31,32 with the impact assessed in terms of
improvement in the treatment of critically ill patients.
However, few studies have been conducted in which
these techniques have been applied outside of the
hospital intensive care unit (ICU).33-35 The adverse
conditions prevailing in an ambulance setting, such
as limited space and vehicle movement with result-
ing discomfort, further hinder communication with
the critical care patient36,37 and negatively affect the
patient’s physical, psychological, and emotional well-
being.38,39 Therefore, additional research on nurse-
patient communication in this context is needed.
This study was conducted to analyze the effect of
implementation of AAC and BCS on the psychoemo-
tional state of critical care patients being transported
by ambulance.
Methods
This study had a quasi-experimental design with
a control group and an intervention group and
involved preintervention and postintervention
measurements of pain, anxiety, and PTSD symp-
toms. The CONECTEM communicative intervention
was used in critical care patients in the intervention
group transported by ambulance, whereas the tra-
ditional care process was used for control group
patients (Table 1).

CONECTEM communicative intervention
Table 1
CONECTEM communicative intervention and
routine communicative action of nonhospital nurses
STRATEGY 1
Communication with the patient according to the training and
guidelines established in the communicative intervention, focusing
mainly on the following:
• Initiate the patient-nurse interaction
• Continuous communication during the journey
• The frequency and duration of the interaction depend on the
patient’s requirements at the time of transportation
• Always maintain eye contact during the interaction
• Pause to allow the patient to process the information
• Clarify and double-check all messages from the patient in
to avoid misinterpretations
• Show empathy, be assertive, and use active listening techniques
• Refrain from making value judgments about patients and/or
their family situation
• Pay attention to nonverbal communication: gestures of pain,
restlessness, or sighing
STRATEGY 2
Communication with the patient according to the training and
guidelines established in the communicative intervention, focusing
mainly on the following:
• Perform the communication actions in Strategy 1
• Highly precise and specific language, using short sentences to
facilitate effective communication
• Establish a signal for yes, one for no, and one for “I don’t understand”
• Use the CONECTEM support material
Boards for conveying emotions
Boards for conveying requirements
International dictionary symbols
• The patient is asked to point or indicate what they wish to com-
municate. If they are unable to do this, the nurse asks them
• Nonverbal communication
Pay attention to gestures of pain, restlessness, or sighing
Physical contact
Relaxing music (use of the CONECTEM musical support material)
STRATEGY 3
Communication with the patient according to the training and
guidelines established in the communicative intervention, focusing
mainly on the following:
• Ensure a peaceful atmosphere, ensuring that devices are silenced and
their alarms are off, and dim the lighting to help the patient to rest
• Be on the lookout for changes in physical signs
• Observe facial expressions and motor movements
• Verbal communication
Initiate the interaction
Explain any relevant and suitable procedures and information to
the patient
Soothing and unhurried tone of voice

are lengthy in both time and distance, and narrow,
winding roads in their territory.
The study population consisted of all critically
ill patients transferred by ambulance to the 4 emer-
gency medical centers chosen. One of the centers
(most convenient for the principal investigator) was
selected for implementation of the CONECTEM com-
municative intervention (the intervention group),
with patients from the other 3 centers constituting
the control group. The nurses caring for the inter-
vention group were previously trained in BCS and
AAC to prepare them for the CONECTEM interven-
tion in the ambulance.
The study sample, recruited from consecutive
cases, was nonprobabilistic. Critically ill patients
were included in the study if they were aged 18 or
older and required transfer by
ambulance to a secondary or
tertiary hospital for either diag-
nosis or treatment. Patients
were excluded if they were
transferred by helicopter.
The sample size was esti-
mated on the basis of the prev-
alence of anxiety in critical care
patients, which is 60%, accord-
ing to the literature.40 With an
of .05 and a power of 80%
to detect a difference of 25%
between the 2 groups and with
estimated losses of 10%, 69
patients were needed in each
group. (Ultimately, 68 patients participated in the
intervention group and 52 patients in the control
group—see Results.)
Data Collection
The emergency medical team nurses from each of
the 4 participating sites were tasked with data collec-
tion. The nurses working at the center where the inter-
vention was carried out collected the data for the
intervention group. Nurses working at the other 3 cen-
ters collected the data for the control group. Data col-
lection began once the patient was in the ambulance
and concluded upon their arrival at the destination.
The mean transfer duration was 1.5 to 2 hours. Three
psychoemotional responses typical in this situation
were assessed: pain, anxiety, and symptoms of PTSD.
The nurses assessed the study variables using validated
scales before and after the CONECTEM intervention
in the intervention group, and before and after trans-
port in the control group. Sociodemographic and
health variables were also collected (sex, age, type of
disease, degree of consciousness, and whether or not
the patient was fitted with an endotracheal tube). The
data collection process lasted 6 months.
Instruments
The Glasgow Coma Scale (GCS)41 was used to
identify the most suitable CONECTEM intervention
strategy for each patient based on their degree of con-
sciousness. This tool was chosen because it is com-
monly used by nurses working outside the hospital,
permitting quick assessment and taking into account
a person’s verbal and motor responses, which influ-
ence communication.
The following instruments were used to assess
the psychoemotional variables of pain, anxiety, and
PTSD symptoms, respectively:
Visual Analog Scale. The visual analog scale (VAS)42
was used to measure the intensity of the pain described
by the patient. The VAS can take the form of centime-
ters or numbers from 0 to 10. Pain was also dichoto-
mized into 2 categories: absence (VAS score of 0)
and presence (VAS score of 1-10).
State-Trait Anxiety Inventory. A modified version
of Spielberger’s State-Trait Anxiety Inventory43 was
used to measure anxiety. This scale consists of 6 items
divided into 2 categories for anxiety: present (anx-
ious, nervous, worried) and absent (calm, comfort-
able, “I feel calm”).
Impact of Event Scale. The Impact of Event Scale44
comprises 15 items: 6 measures of intrusion, 8 of
avoidance, and 1 of hyperactivity. The score for each
item ranges from 0 to 5, with 0 indicating never, 1
rarely, 3 sometimes, and 5 often. A total score is cal-
culated, with higher values indicating greater stress
levels. A total score of less than 8.5 indicates mild
stress; 8.5 to 19, moderate stress; and greater than
19, severe stress.
If the patient has a GCS score of less than 9 and is
receiving mechanical ventilation, it has been recom-
mended that the patient’s pain be measured using the
Behavioral Pain Scale45 and the patient's agitation-
sedation state be measured using the Ramsay Sedation
Scale and the Richmond Agitation-Sedation Scale.46 A
case report form was used to collect data on sociode-
mographic and health variables.
Intervention and Intervention Protocol
The CONECTEM intervention consists of BCS
such as visual contact, message clarification, empa-
thy, and active listening47 and uses AAC techniques
such as panels with icons representing requirements
and emotions and the international dictionary
signs. 29,48 Other AAC techniques such as writing

on a board or using advanced technology were ruled
out because of the difficulty and complexity of per-
forming them during the ambulance transfer (ie,
vehicle movement, narrow roads, the time needed
to show the patient and nurses how an electronic
device works, and the patient’s condition). The inter-
vention was designed by a group of experts who
approved its application during ambulance trans-
port. Before use of the CONECTEM intervention,
the nurses who wished to participate in the study
underwent a training program that qualified them
to carry out the intervention in the ambulance. The
training was organized into 3 modules: the anthro-
pology of communication, the psychoemotional state
of the critically ill patient, and the BCS and AAC used
in CONECTEM. The training lasted 6 hours spread
over 2 days. The training methods used were role
playing and case management. To be able to per-
form the CONECTEM intervention, nurses were
required to pass a theoretical-practical posttraining
test with a score of at least 70%.
The intervention was split into 3 different strate-
gies according to the patient’s level of consciousness.
Each strategy entailed a certain level of verbal and non-
verbal communication. In contrast, nurses caring for
patients in the control group used routine communi-
cative action that relies on the nurse’s social and com-
munication skills. The CONECTEM intervention
and the routine communicative action are described
in greater detail in Table 1.
Statistical Analysis
In the descriptive analyses, number and percentage
were used for categorical variables, whereas median and
SD were used for quantitative variables. The normality
of the quantitative variables was verified with the
Kolmogorov-Smirnov test. Either the t test or the Mann-
Whitney U test was used for analysis of the quantitative
variables, depending on the data distribution. Either the
2 test or the Fisher exact test was used for analysis of
the categorical variables. To analyze the impact of
the intervention on the dependent variables (pain and
PTSD symptoms), we performed multivariate analysis
of covariance of the pretest-posttest differences between
the intervention group and the control group (intro-
ducing the pretest score as a covariable). Finally, we
conducted repeated-measures analysis of variance for
the pain and PTSD symptom variables. The Pearson
product-moment correlation was used to calculate the
relationships between pain, anxiety, and PTSD symp-
toms. A P less than .05 was considered to indicate statis-
tical significance. IBM SPSS Statistics, version 17.0, was
used for the statistical analysis.
Ethical Considerations
The project was approved by the independent
ethics committee of Spain’s regional university
(INF-2014-17) and by the board of directors of
Spain’s emergency medical system (20150120_21).
The study was guided by the Helsinki Declaration
on ethical principles for medical research involving
human participants. Each patient or guardian and
each nurse working in the intervention and control
groups signed an informed consent form to partici-
pate in the study and was assured of confidentiality
and data anonymity.
Results
Participant Flow
Twelve nurses of the 22 eligible for work with
the intervention group were enrolled and trained in
the CONECTEM intervention. All nurses in this group
carried out the intervention in the ambulance. A total
of 138 critically ill patients were consecutively enrolled
in the study: 69 patients in the intervention group
and 69 in the control group. Seventeen patients were
excluded from the control group because of missing
information on the measurement scales, and 1 patient
was excluded from the intervention group because
of not being an interhospital transfer (see Figure).
Baseline Data
The mean (SD) age of the 120 patients in the final
sample was 63.4 (17.7) years. Of the 120 patients,
48 (40.0%) were female. The most common disease

and neurological disease (25 patients [20.8%]).
Ninety-eight (81.7%) of the patients were conscious
and oriented (GCS score, 15), 18 (15%) were con-
scious and disoriented (GCS score, 9-14), and only
4 (3.3%) were intubated and receiving mechanical
ventilation (GCS score, ≤8) (Table 2). The psychoemo-
tional variables were analyzed for patients with a
GCS score of greater than 9 (n = 115), as intubated
patients were somewhat underrepresented.
The prevalence of pain was 68.7% (95% CI,
59.8%-76.7%), with a mean score of 2 of 10 on the

mild symptoms. The pretest sociodemographic and
psychoemotional variables did not differ significantly
between the 2 groups, with the exception of PTSD
symptoms, with a greater percentage of patients in
the intervention group having few or no symptoms
(P = .007) (Table 2).
Effectiveness of the CONECTEM Intervention in
Improving Psychoemotional State
The results of multivariable analysis of covari-
ance with pretest-posttest differences showed statis-
tically significant differences between groups (Pillai
multivariate, F
2,110
= 57.973, P < .001). The univariate
analysis of variance results showed an association
between the intervention and improvement in pain
and PTSD symptoms in the intervention group
(P < .001; Table 3).
In the comparison of anxiety (improvement or
nonimprovement) between the 2 groups, a greater
percentage of patients with improvement was found
in the intervention group (62% vs 4%), with the
difference being statistically significant (P < .001;
Table 4).
Correlations Among Pain, Anxiety, and PTSD
Symptoms in the Posttest Period
The Pearson product-moment correlation test
indicated significant correlations among the 3 psy-
choemotional variables: pain and anxiety (r = 0.37),
pain and PTSD symptoms (r = 0.33), and PTSD symp-
toms and anxiety (r = 0.51) (P < .05 for all). These
correlation coefficients demonstrated moderate cor-
relation among the 3 variables.
Discussion
Effectiveness of CONECTEM Communication
Strategies
The ability of nurses and critical care patients to
interact is fundamental to their effective communi-
cation.20,30 The results of this study demonstrate that
the actions constituting the various CONECTEM
communication strategies were effective in improv-
ing the psychoemotional state of the critical care
patients transported by ambulance. Other studies
based on BCS have also indicated improvement in
patient communication and level of satisfaction with
care.49-51 In addition, the use of AAC techniques
with critical care patients facilitates nurse-patient
communication52 and relieves pain53 and psychoemo-
tional symptoms such as anxiety54 and depression,55
helping to improve nursing treatment.6,11,56 However,
we found no studies on critical care patient–nurse
AAC in the nonhospital setting, making it impossible
to compare the effects of AAC on patients in this set-
ting with the effects on patients subsequently admit-
ted to the ICU. Although Eadie et al34 reported that
AAC in the ambulance improved communication
between paramedics and patients, the literature is still
insufficient to compare the scope of AAC in this field
and what effects it might have on a patient who is
later admitted to a hospital ICU.
Effectiveness of the CONECTEM Intervention in
Improving Pain, Anxiety, and PTSD Symptoms
Pain. Pain is one of the most common symptoms
in critical care patients, regardless of their disease,
with a prevalence of 70% to 87%.57-59 In this study,
the prevalence of in-ambulance pain in critical care
patients was 68.7%. Given the difficulty of measuring
pain in critically ill patients, several studies have been
conducted on how to increase the effectiveness of the
communication of pain between patient and nurse.60,61
Nurses’ training in communication skills affects their
ability to accurately gauge the patient’s degree of pain
and determine whether or not the patient needs anal-
gesic treatment.32,54,62 In the same vein, the results of
