Abstract

Background

Pregnancy and the postpartum period are times of great change for women and their partners, often bringing substantial challenges and stress. Approximately 10%–20% of women suffer from mood disorders such as depression in the perinatal period. There are risks involved in using psychopharmacological interventions to treat perinatal depression. Mindfulness and compassion-based educational programs could be efficacious and cost-effective options for the prevention and treatment of perinatal mood disorders. The aim of this study is to assess the efficacy of an adapted Mindfulness-Based Childbirth and Parenting (MBCP) program that includes compassion training for pregnant women in primary care (PC) settings in the Spanish National Health System to decrease perinatal depression.

Methods

A multicenter randomized controlled trial (RCT) will be conducted. Participants will be pregnant women (n = 122) and their partners who wish to participate. They will be enrolled and assessed in PC settings and randomly assigned to either: (1) an adapted MBCP educational program tailored to the Spanish National Health System + treatment as usual (TAU); or (2) TAU only. The main outcome to be assessed will be depression, evaluated with the Edinburgh Postnatal Depression Scale (EPDS). Secondary outcomes will include self-reported measures of perceived stress, affects, mindfulness, self-compassion, maternal self-efficacy, and use of health and social services. Patients will be assessed at four timepoints: baseline; post-treatment; and at three and six months after childbirth. Intention-to-treat and per-protocol analyses will be carried out using linear regression mixed models. Effect sizes will be estimated using Cohen’s d.

Discussion

Perinatal depression is a significant health problem. An effective and low-cost childbirth education program that incorporates mindfulness and compassion practices may be a beneficial preventive complementary healthcare modality for expectant women and their partners. This study will be the first multicenter RCT in Spanish PC settings using adapted MBCP and compassion practices to reduce symptoms of depression during pregnancy and the postpartum period.

Background

Perinatal depression (PD), which includes major and minor depressive episodes that occur during pregnancy and/or in the first 12 months after delivery, is one of the most common conditions that can develop during pregnancy and the postpartum period [1]. The prevalence of PD in developing countries is approximately 20%; in developed countries, it is in the range of 10%–15% [2]. Untreated PD can have devastating effects on women, infants, and their families [3,4,5], so much so that NICE guidelines in the UK recommend screening for PD in primary care (PC) settings [6].

Prenatal depression is one of the main risk factors for postpartum depression. It often goes undiagnosed and untreated, with serious consequences for the mother and, by extension, the infant, including growth delays in the developing fetus, prematurity, low birth weight, disorganized infant sleep patterns, and less responsiveness to the external environment [4]. Among Spanish women, the prevalence of prenatal depressive symptoms is approximately 15% [7]. In addition, prenatal depression appears to affect men; thus, the importance of the presence of the partner in interventions tailored to improve couple wellbeing during pregnancy and postpartum is encouraged [8, 9].

Other risk factors for postpartum depression include a young age (e.g. the prevalence of postpartum depression in teenage mothers is much higher than for adult mothers), a previous history of depression, and the presence of postpartum blues: a transient mood disorder characterized by mild depressive symptoms that is common in new mothers [10,11,12,13]. A large-scale study conducted in Spain [14] found rates of minor postpartum depression was in the range of 11%–17%, while major postpartum depression was in the range of 8%–11%. Given the prevalence of PD and the adverse effects of this disorder for women, children, and families [3,4,5], the development and implementation of cost-effective programs and interventions have important health implications. Usual treatments for PD include counseling, psychotherapy, and antidepressant medication. However, there is evidence of risks to both the fetus and breastfeeding infants that limits the use of antidepressants [12, 15], and antidepressant exposure during pregnancy may increase susceptibility to disorders such as hypertension for the expectant woman [16].

Mindfulness-based programs (MBPs) are educational mind–body courses that have the specific purpose of training the mind through meditation practice to adopt a non-judgmental awareness focused on the present moment [17]. In addition, compassion is a particular orientation of the mind that recognizes the universality of suffering in the human experience and cultivates the capacity to meet that suffering with kindness and empathy [18]. It is characterized by the presence of sensitivity to suffering and a commitment to prevent and alleviate it with equanimity and patience [19]. Evidence is growing that compassion is an important mechanism in MBPs and some researchers advocate explicit compassion training within MBPs [20].

MBPs have shown to be beneficial for those with symptoms of depression and other mental disorders [21, 22]. Moreover, some evidence suggests that learning and practicing mindfulness skills during pregnancy may improve both a mother’s symptoms of depression and a baby’s weight at birth [23]. Incorporating mindfulness and compassion into childbirth education could offer pregnant women and their partners at risk for PD, or currently experiencing depression, an alternative strategy for addressing this mood disorder without the stigma that can be associated with psychotherapy or counseling and the risks of antidepressant medication for the mother and the baby [24]. It may also offer a preventive strategy accessible to all pregnant women, as PD can arise without previous risk factors [12].

In addition, mindfulness training has been used as a tool for coping with both chronic and acute pain [25,26,27,28]. Thus, a mindfulness and compassion-based program could be useful for expectant women for coping with pain and discomforts often encountered during pregnancy, for childbirth-related pain as well as pain that can arise in the postpartum period, including during breastfeeding. This approach could provide an innovative and complementary skills-based educational approach that promotes physical and mental health and wellbeing during pregnancy, childbirth, and the postpartum period. Such a program could also be beneficial for pregnant women suffering from PD who prefer to avoid medications that may have adverse effects on the fetus and themselves [29], for women who wish to be as thoroughly prepared as possible for whatever may arise during childbirth [30], and for women who have a disposition for making positive behavior changes to improve their physical/mental health during pregnancy [31].

Programs such as Mindful Motherhood [32], Mindfulness-Based Childbirth Education (MBCE) [33], MindBabyBody [34], and the Mindfulness-Based Childbirth and Parenting (MBCP) program [35] have adapted mindfulness training for pregnancy, childbirth, and the postpartum period. MBCP, from which the protocol used in the present study has been specifically adapted, has been shown to decrease fear of childbirth [36] and led to important maternal mental health benefits including improvements in childbirth related appraisals and prevention of postpartum depression symptoms [24]. Other programs, which have been adapted from Mindfulness-Based Cognitive Therapy (MBCT) [37,38,39], have targeted pregnant women suffering from anxiety and depression and have yielded promising results. In addition, researchers in compassion-focused therapy (CFT) have created compassion interventions for prevention and treatment of PD [40, 41].

The Spanish National Health System (NHS) provides free universal healthcare regardless of financial condition or nationality. However, most regions in Spain do not have specific healthcare professionals who take care of women’s perinatal mental health. With approximately 400,000 births per year in Spain [42], cost-effective and accessible interventions for those coping with PD—as well as a strategy for prevention—are greatly needed. Within this context, the primary aim of the present study will be to compare the effectiveness of an adapted MBCP program with compassion practices that includes treatment as usual (TAU) tailored for delivery in the Spanish NHS and implemented in the second trimester, with an active control group receiving TAU only, to assess possible improvements in depressive symptomatology in pregnant women.

Methods

Study design

This is a multicenter randomized controlled trial (RCT) with two parallel groups: (1) adapted MBCP educational course with compassion practices delivered for pregnant women and their partners + TAU; and (2) TAU only, which consists of a childbirth education course provided by PC midwives. This protocol has followed the SPIRIT guidelines [43] Additional file 1. The trial registration number of the study is ClinicalTrials.gov NCT03247491.

Setting and study sample

Participants will be pregnant women in the second trimester of pregnancy living in the city of Valladolid (Spain) who are served by the Spanish NHS. Partners of the expectant women will be encouraged to participate in the courses. Participants considered for inclusion will be: (1) women in weeks 6–25 of pregnancy; (2) able to read, write, and understand Spanish; (3) age ≥ 18 years ; and (4) have signed a written informed consent document following an informed consent procedure. Exclusion criteria will include: (1) any diagnosis of disease that may affect the central nervous system, such as brain pathology or traumatic brain injury; (2) other psychiatric diagnosis or acute psychiatric illness, such as substance dependence or abuse, a history of schizophrenia or other psychotic or eating disorders; (3) any medical, infectious, or degenerative disease that may affect mood; (4) presence of delusional ideas, hallucinations, or at risk for suicide; and (5) currently under psychopharmacological medication or under psychopharmacological treatment.

Sample size

The sample size estimation was based on the expectation of a moderate standardized mean difference between groups on depressive symptoms at post-birth of d = 0.59. Like the protocol that will be used in the present study, this effect size was found in a recent RCT that used a modified MBCP program [24] compared to a TAU active standard childbirth preparation course with no mind–body components. This effect size is also similar to that obtained in other studies using other programs [44], a pilot study evaluating the effectiveness of MBCE [33], a cohort study assessing the MindBabyBody program [34], and a brief pilot adaptation based upon the MBCP program [9]. Considering a statistical power of 80%, a 5% significance level in a between-group interaction with a local alpha of 0.017 in the first test—using Benjamini–Hochberg’s procedure—and a dropout rate in the range of 15%–20%, as has been observed in these types of studies [45], 61 participants are needed in each group, for a total sample size of 122 women.

Recruitment

Participants will be recruited from 11 PC urban healthcare centers in the city of Valladolid, Spain through referrals from midwives and obstetricians. When a health provider identifies a pregnant woman who might be a potential participant, they will facilitate contact with the primary study researcher who will arrange a meeting with both the pregnant woman and her partner. During this interview, the study characteristics will be explained, including the main objectives, potential benefits and adverse events, an explanation regarding the assigned home meditation practice, and the option to end their participation in the study at any time. Partners will be encouraged to participate in all of the sessions and the assigned home practices. If a pregnant woman is interested in taking part in the study, the researcher will give her an information booklet with additional details describing the trial. Within three days after having signed the written informed consent form, participants will be interviewed by an independent researcher who will administer the MINI International Neuropsychiatric Interview [46] in order to assess eligibility related to the inclusion and exclusion criteria. If the pregnant woman fulfills all of the study criteria, the same researcher will administer the baseline tests. An independent researcher will conduct the randomization procedure after the baseline assessment. Recruitment will be done consecutively to complete the sample size over an expected 24-month period. Flowcharts giving an overview of the study design and the study timeline are summarized in Figs. 1 and 2, respectively.

Randomization, allocation, and masking of study groups

Women who want to participate in the trial who fulfill the study criteria will be assigned consecutive numbers and will be allocated to one of the two study groups using a simple – not stratified – random number sequence using a computer program generated by a member of the research team who does not know the study aims. The allocation will be carried out by a researcher of the “Primary Care Prevention and Health Promotion Research Network” (REDIAPP) who is not involved in the study. The number sequence will be concealed until intervention groups are assigned. Thus, participants will have to agree to participate in the study before the randomization process and will not be informed of their group allocation until after completion of the pre-treatment measures. Because of the nature of the intervention, participants cannot be blinded to their group allocation. Study personnel conducting psychological assessments will be masked to participants’ treatment conditions and will be specially advised not to ask for this information. The researcher who administers the baseline assessments will be unaware of which treatment group the patient will be assigned. This researcher will be different from the one who will facilitate the rest of study assessments by means of an online procedure. Midwives and obstetricians will be also unaware of the patients’ randomized assigned group for as long as possible. In addition, the statistician who will conduct the primary analysis of the data will be blind to which condition the patient is assigned.

Interventions

All participants included in the study, whether they receive the adapted MBCP program with compassion practices or not, will be treated by their general practitioner (GP), obstetricians, and midwives according to TAU at a PC level. Women who belong to the same health center will receive the TAU from the same staff. The adapted MBCP program arm will receive a combined treatment, which consists of the MBCP program with compassion practices tailored to the Spanish NHS plus TAU. The program will take place during the second trimester of pregnancy, before participating in the TAU childbirth classes that are taught at their site during the third trimester.

Treatment as usual (TAU)

TAU consists of a childbirth education program that is offered at no charge to pregnant women and their partners by the local midwives in PC facilities in the Spanish NHS. Women usually attend this program in groups of 8–12 couples in the third trimester of pregnancy (during weeks 28–36). It covers basic topics about pregnancy, delivery, postpartum, breastfeeding, and care of a newborn baby. The duration of the TAU course is usually 16 h and includes both information-based classes and some instruction in basic relaxation and breathing techniques to cope with new stressful situations.

Adapted MBCP with compassion practices tailored to the Spanish NHS

The main objective of the MBCP program [47] is to teach mindfulness meditation for decreasing stress during pregnancy, reducing pain and fear during childbirth, to support parenting with wisdom and compassion, and to interrupt intergenerational patterns of suffering [48]. The course schedule is 3 h once a week for nine weeks, a 7-h silent practice day on the weekend between classes 6 and 7, and a reunion class after all the women have given birth. Although the MBCP program is designed for couples, pregnant women without a partner or whose partner cannot attend are also welcomed, as are pregnant women with other support people. A recommended class size is 8–12 couples. Various formal mindfulness meditation exercises are practiced in each class; participants are also asked to practice the meditations daily at home using audio recordings throughout the course. Formal mindfulness meditation and the attitudes cultivated in a mindfulness practice are fully integrated into the curriculum, which also includes instruction regarding the physiology and mind–body dimensions of pregnancy, labor, childbirth, breastfeeding, adjustment in the postpartum period, and attending to the needs of a newborn. Mind–body pain coping skills for childbirth and awareness skills for coping with stress in daily life are also taught. Other elements include encouraging a sense of connection or community among participants in order to minimize social isolation and its resulting negative effects on the mental health of new parents.

The intervention that will be used in this study is an adaptation of the basic MBCP program to: (1) include an explicit compassion component; and (2) be tailored to fit the Spanish population and the existing NHS programs for expectant women and their partners, improving adherence. It will be implemented at a PC level, with a duration of 10 sessions (eight sessions before childbirth and two sessions after childbirth, at three months and six months postpartum). Each class in this adapted MBCP program is 2 h long. Because all women receive free childbirth education classes from their midwives at their PC center, the adapted MBCP program will offer the mindfulness and compassion meditation practices from the original MBCP program without the childbirth information. In addition, this Spanish adaptation does not include the silent day of mindfulness practice as in the original MBCP program. While the value of this day of practice is clear, it is logistically difficult to implement it within the Spanish healthcare context as the PC facilities are closed during the weekends. However, the practices taught during the day of silence in the foundational MBCP program will be included in class 7. This class 7 has been adapted to cover all the practices offered during the course as well as the silent retreat day, including walking meditation and an interpersonal mindful speaking and listening inquiry between partners. There will be four adapted MBCP groups, with approximately 15 pregnant participants and their partners in each group. All of the classes will be held at same health center location. The total number of hours in the adapted MBCP program, including the TAU, will be 36.

During the adapted MBCP program with compassion exercises, participants will learn 14 formal mindfulness and compassion practices: awareness of breathing meditation; body scan meditation; compassionate body scan meditation; being with baby meditation; mindful yoga; walking meditation; creating a safe place meditation; loving-kindness meditation; sitting meditation; self-compassion meditation; coping with pain ice cube meditations; a three-step breathing meditation; compassionate touch meditation; and interpersonal mindful speaking and listening meditation. Participants will receive audio recordings of each of these practices to be used in their assigned daily home practices. All the participants will be asked to keep a daily diary of their home practice, as well as a calendar of pleasant and unpleasant events. See Appendix for a detailed description of all the elements of the adapted MBCP program.

Instruments

All participants included in the trial will be assessed at pre-test/baseline, post- intervention, and at three and six months after childbirth (approximately six and 12 months after inclusion). The study instruments that will be used are summarized in Table 1.

Table 1 Study instruments
Full size table

Main outcome

The primary outcome will be depressive symptom severity as assessed by the Edinburgh Postnatal Depression Scale (EPDS) [49]. The EPDS is a 10-item self-report scale used to assess the common symptoms of depression (e.g. “I have blamed myself unnecessarily when things went wrong”) during the perinatal period, both pre- and postnatally. It is one of the most widely used instruments to evaluate the severity of PD in clinical trials [50]. Each item of the EPDS is scored on a 4-point scale (from 0 to 3), with the total scale score in the range of 0–30. The validated Spanish version of the EPDS has a cutoff point of ≥ 11 to identify the presence of probable perinatal depression in women, obtaining an area under the curve of 0.98, with also good sensitivity and specificity values [51].

Secondary outcomes

A list of sociodemographic variables, such as age, marital status, education, occupation, nulliparity, and any previous depression episodes will be collected.

The Perceived Stress Scale (PSS) [52] is a widely used self-report instrument that evaluates the degree to which situations in one’s life are appraised as stressful. Items are designed to assess how unpredictable, uncontrollable, and overloaded respondents have found their lives to be during the last month. It consist of 14 items (e.g. “In the last month, how often have you found that you could not cope with all the things that you had to do?”) with a 5-point response scale from 0 (“never”) to 4 (“very often”) and a total score in the range of 0–56. Higher scores indicate greater perceived stress. The validated Spanish version of the PSS, which has demonstrated appropriate psychometrics, will be used [53].

The Positive and Negative Affect Schedule (PANAS) [54] consists of two 10-item scales that provide measures of positive affect (e.g. “interested”) and negative affect (e.g. “irritable”), with answers ranging in a Likert-type scale from 1 (“very slightly or not at all”) to 5 (“extremely or very much”). Participants are asked to rate the extent to which they have experienced each affective state, resulting in a total score in the range of 10–50. The Spanish version of the PANAS, adapted with adequate psychometrics and designed to assess affective states over the last week, will be used [55].

The Five Facet Mindfulness Questionnaire (FFMQ) [56] evaluates five facets of personal disposition towards being mindful in daily life situations. It is composed of 39 items to assess the subscales of observing (e.g. “When I’m walking, I deliberately notice the sensations of my body moving”), describing (e.g. “I’m good at finding words to describe my feelings”), acting with awareness (e.g. “When I do things, my mind wanders off and I’m easily distracted” – item reversed), non-judging of inner experience (e.g. “I make judgments about whether my thoughts are good or bad” – item reversed), and non-reactivity to inner experience (e.g. “I perceive my feelings and emotions without having to react to them”). The FFMQ is rated on a Likert-type scale, ranging between 1 and 5 points (from 1 = “never or very rarely true” to 5 = “very often or always true”). Total scores are in the range of 39–195, being that a high score indicates a high level of dispositional mindfulness. The validated Spanish version of the FFMQ that has demonstrated appropriate psychometric properties will be used [57].

The Self-Compassion Scale (SCS) [58] is a self-report measure of self-compassion. It consists of 26 items that assess how respondents perceive their actions toward themselves in times of difficulty, measuring facets of self-kindness (e.g. “I try to be loving towards myself when I’m feeling emotional pain”), common humanity (e.g. “I try to see my failures as part of the human condition”), and mindfulness (e.g. “When I’m feeling down, I tend to obsess and fixate on everything that is going wrong” – item reversed). Items range between 1 (“almost never”) to 5 (“almost always”). The SCS has shown appropriate psychometrics, and it allows for a unidimensional total score in the range of 26–130 [59]. The validated Spanish version of the SCS will be used [60].

The Parental Evaluation Scale (EEP) [61] is a self-administered measure to assess self-efficacy feelings about motherhood in women with children aged 0–2 years. It is composed of 10 items (e.g. “I feel like I do a good job as a mother”) that use a 10-point Likert-type scale from 0 (“Totally disagree”) to 10 (“Totally agree”). The EEP gives a global score of maternal self-efficacy in infants’ mothers in the range of 0–100, with higher values indicating greater self-efficacy. The validated Spanish version of the EEP has demonstrated appropriate psychometric characteristics [61].

The Client Service Receipt Inventory (CSRI) [62] is a questionnaire for gathering information about the use of healthcare and social services, as well as other economic variables (e.g. time of sickness absence, etc.). The version that will be used in this study has been designed to collect retrospective data on service utilization during the previous six months from baseline assessment and from the six-month follow-up measure. The CSRI-Spanish validated version, that has good psychometric properties, will be used [63].

Analysis strategy

Results will be reported according to the CONSORT guideline statement [64]. Sociodemographic data at baseline will be presented by means of frequencies (percentages), medians (interquartile range), and means (SD), according to their level of measurement and statistical distribution. Visual inspection on the baseline data will be carried out to check the success of randomization through the two treatment conditions.

The primary efficacy analysis will use an intention-to-treat (ITT) base comparing the main outcome – EPDS – between arms in all the time points as a continuous variable. We will use a repeated measures (RM) design using linear mixed-effects regression models, including participants and the corresponding health center in the random part of the model, by means of the restricted maximum likelihood method (REML). Estimations of slope coefficients (and their 95% confidence intervals [CI]), adjusted for age, nulliparity, previous episodes of depression, and timing of receipt of intervention, will be calculated. To observe the specific trajectories through the study and to evaluate whether possible differences caused by the condition treatment are consistent over time, we will consider the “treatment × time” interaction. In parallel, a per-protocol analysis, with a minimum dose assumed to be ≥ 50% attendance [65], will also be carried out.

If missing data occur in the sample, multiple imputations by using chained equations to replace missing values will be calculated after ensuring data are missing at random (MAR), and as long as there are < 40% missing data in the corresponding variable to ensure validity of imputations [66]. Cohen’s d statistic, as an effect size (ES) measure of group differences will be estimated by means of pooled pre-test SDs to weight for the differences in the pre–post means [67]. Values of d = 0.20 are regarded as small, 0.50 as medium, and 0.80 large. Secondary analyses will comprise the PSS, PANAS, FFMQ, SCS, and EEP, and will use the same analytical strategy described above.

Cost-effectiveness and cost-utility procedures of analysis will also be conducted calculating incremental cost-effectiveness (ICER) and incremental cost-utility (ICUR) ratios. The effectiveness of the interventions will be estimated by means of the difference between the EPDS score at baseline and at follow-up; utility will be estimated using quality-adjusted life-year (QALYs) at follow-up. QALYs will be calculated using the area-under-the-curve (AUC). In addition, cost-utility planes will be plotted.

The overall alpha level will be set at 0.05 using two-sided tests and considering Benjamini–Hochberg’s correction for the primary outcome analyses as a way to balance between errors. However, no corrections will be made for secondary outcome analyses.

Discussion

MBPs are effective alternative strategies for improving mental and physical health and wellbeing [65], for reducing symptoms of depression [22], for preventing depression relapse [68], and for managing pain and reducing stress [25, 26, 69]. They have also been proposed as potentially beneficial for expectant parents preparing for childbirth for managing pain during pregnancy and labor, reducing the risk of PD, and increasing the availability of parental attention for the infant [70]. With these last aims, several MBPs have specifically been adapted for this population [32,33,34,35, 37,38,39]; some of them have also included compassion techniques [40, 41].

No particular difficulties are expected in relation to recruitment of participants for the present study. However, since recruitment of participants will depend to a large extent on the attitudes of the PC providers who will be recommending the program to their patients, the study will be explained to them in detail before recruitment begins. It is expected that by providing this pre-recruitment information to PC physicians, possible negative attitudes about the study will be minimized.

Other potential difficulties may be that since patient participation in the study will be voluntary, there could be a higher rate of drop-out due to unforeseen life circumstances or conditions arising from the health of the mother or baby. Additionally, the only measures to be used in this study will be self-report questionnaires. Therefore, the data collected will have the limitations of this particular methodology.

Clinical implications

To the best of our knowledge, this is the first study aiming to implement an adapted MBCP program which specifically adds a compassion component for preventing and treating PD in the Spanish healthcare context. If positive results are achieved, it could have a high impact on this important mental health issue that affects not only women but their partners and their newborn children [4, 5]. Moreover, if this intervention is cost-effective, it could be economically suitable for implementation in PC health centers throughout Spain. Currently, childbirth education classes in Spain are offered by midwives free of charge in all the PC health centers. If midwives were trained to teach this adapted MBCP program, pregnant women, their infants, and their partners might experience important and multiple benefits that come from learning mindfulness and compassion skills and practices for preventing PD.

Trial status

The protocol version is 3 (25/09/2018). Recruitment began on June 2017 and will finish approximately on June 2019.

Ethics declarations

Ethics approval and consent to participate

Written informed consent will be obtained from participants before their baseline assessment and group assignment. Before they give consent, participants will be provided with general information about the objectives and characteristics of the study. They will also be informed that participation in the study is voluntary, that they can choose to withdraw at any time, and are guaranteed to continue to receive the care considered most appropriate by their PC midwife and obstetrician regardless of study participation. The study follows Helsinki Convention norms and posterior modifications, and the Declaration of Madrid of the World Psychiatric Association. For ethical reasons, patients allocated to the TAU arm will be offered the option to attend mindfulness and compassion training after the trial is finished. Participants’ data will be encrypted and stored according to the 2018 New European Data Protection Law. Ethical approval was obtained from the ethics committee of the hospital that coordinates the 11 PC centers belonging to that hospital clinical area (the Research Commission from the University Hospital “Rio Hortega,” reference approval number: 50/2014/04). In the Spanish National Health System, when approval is received from the hospital ethical committee, a trial can be conducted in all PC centers belonging to that hospital clinical area.
