Abstract
Background
This new clinical practice guideline concerns the psychosocial diagnosis and treatment of patients before and after organ transplantation. Its objective is to establish standards and to issue evidence-based recommendations that will help to optimize decision making in psychosocial diagnosis and treatment.
Methods
For each key question, the literature was systematically searched in at least two databases (Medline, Ovid, Cochrane Library, and CENTRAL). The end date of each search was between August 2018 and November 2019, depending on the question. The literature search was also updated to capture recent publications, by using a selective approach.
Results
Lack of adherence to immunosuppressant drugs can be expected in 25–30% of patients and increases the odds of organ loss after kidney transplantation (odds ratio 7.1). Psychosocial interventions can significantly improve adherence. Meta-analyses have shown that adherence was achieved 10–20% more frequently in the intervention group than in the control group. 13–40% of patients suffer from depression after transplantation; mortality in this group is 65% higher. The guideline group therefore recommends that experts in psychosomatic medicine, psychiatry, and psychology (mental health professionals) should be involved in patient care throughout the transplantation process.
Conclusion
The care of patients before and after organ transplantation should be multidisciplinary. Nonadherence rates and comorbid mental disorders are common and associated with poorer outcomes after transplantation. Interventions to improve adherence are effective, although the pertinent studies display marked heterogeneity and a high risk of bias.
Organ transplantation is indicated in patients facing end-stage organ failure due to severe chronic disease or acute organ injury and for whom no other equivalent treatment options are available for the improvement of their health status. In addition, transplant patients are confronted with physical, mental, and social challenges and stressors in all phases of the treatment process (1). These may be comorbid mental health disorders such as depression and anxiety disorders that accompany or precede the physical disease and negatively impact the entire disease course (2, 3). In a certain proportion of transplant patients, mental health factors are also causally linked to the development and deterioration of the physical disease and therefore require adequate medical treatment. Examples include dependence disorders involving, for example, alcohol and nicotine, with their known physical sequelae such as alcohol-related liver disease, alcohol-related heart failure, and chronic obstructive pulmonary disease.
The treatment of transplant patients should be carried out in a multidisciplinary approach in close collaboration between organ medicine, mental health professionals (MHP, eBox), transplant care, hospital pharmacists, and self-help organizations.
The new clinical practice guideline (4) deals with the psychosocial diagnosis and treatment of patients before and after organ transplantation, including living organ donation. Its objective is to establish standards for psychosocial diagnosis, for establishing the indication, and for the delivery of psychosocial treatments, as well as to issue evidence-based recommendations that will help to optimize decision-making in the psychosocial diagnosis and treatment of transplant patients. The guideline is designed to complement the guidelines on transplant medicine issued by the German Medical Association (Bundesärztekammer).
This publication examines more closely the following central questions (key questions 1–3):
Is nonadherence a risk factor for the prognosis of patients after organ transplantation?
Can psychosocial interventions improve adherence after organ transplantation?
What are the risk factors for a poor prognosis after transplantation?
Methods
The guideline was developed in line with the requirements of the German Association of Scientific Medical Societies (Arbeitsgemeinschaft der wissenschaftlichen medizinischen Fachgesellschaften) for an S3 guideline (5). The German Society for Psychosomatic Medicine and Medical Psychotherapy (Deutsche Gesellschaft für Psychosomatische Medizin und Ärztliche Psychotherapie e. V., DGPM) and the German College of Psychosomatic Medicine (Deutsche Kollegium für Psychosomatische Medizin e. V., DKPM) are the responsible and publishing scientific societies. A broad-based, representative guideline group made up of 17 medical, psychological, pharmaceutical, and nursing societies from Germany and Austria and involving the participation of patient and family representatives was responsible for the development of the new guideline (eTable 1, eTable 2).

A systematic search was conducted in at least two databases (Medline, Ovid, Cochrane Library, and CENTRAL). The literature search was carried out between August 2018 (key questions 1–3) and November 2019 (additional key questions). The results of the literature review for key questions 1–3 are presented by way of example in the eFigure. A non-systematic literature review was undertaken for this article.
The structured consensus development process took place in the period between 25.3.2019 and 24.03.2022 in a total of 12 in-person or web-based structured consensus conferences with neutral moderation by the AWMF. The proposals were discussed by the mandate holders, modified where appropriate, and adopted with a consistently strong consensus. In a final step, the guideline was adopted by the boards of the participating scientific societies in the period between 26.04.2022 and 14.08.2022.
Results
Nonadherence as a risk factor for prognosis after organ transplantation
Across all organ entities, nonadherence in adult patients in relation to immunosuppressant drug use, diet, physical activity, and other health measures ranges from 19 to 25 cases per 100 patients per year (PPY). This is the result of a meta-analysis of 147 studies (6). Nonadherence in relation to the use of immunosuppressant drugs was highest among patients following kidney transplantation (36 ± 2.3 cases per 100 PPY) compared to other organs (7–15 cases per 100 PPY). With regard to the implementation of dietary recommendations, a nonadherence prevalence across all organs of 25 (± 3.4) cases per 100 PPY was seen, while the nonadherence prevalence for physical activity was 19 (± 2.1) cases per 100 PPY. Post-heart transplant patients had a particularly high nonadherence rate for physical activity with 33.7 (± 4.5) cases per 100 PPY compared to other organ transplantations (9–22 cases per 100 PPY). Interestingly, studies in which adherence was measured using self-rating instruments showed the highest nonadherence in relation to the use of immunosuppressant drugs (39.2 cases per 100 PPY).
Especially nonadherence to immunsuppressant drug use is a relevant aspect in the treatment of organ transplant patients (6– 8, e1– e4). Nonadherence to the use of immunosuppressant drugs is associated with an increased risk for graft rejection and increased mortality (9– 11) and is one the commonest preventable causes of organ loss. The majority of available studies are on patients following kidney transplantation. Approximately 20% of late acute organ rejection episodes and 16% of cases of graft loss following renal transplantation can be attributed to nonadherence (38 studies) (12). Another review article of 36 studies concluded that a median of 36% (interquartile range 14–65%) of graft losses following renal transplantation were associated with nonadherence. The relative chance of graft loss in nonadherent patients was 7.1 times (95% confidence interval: [4.4; 11.7]) higher compared to adherent patients (13). Some studies demonstrated that even in the case of a rate of adherence to immunosuppressive medication of ≤ 98%, one must assume a worsening in clinical outcome (e5– e7).
The guideline group therefore recommends that pharmacological and non-pharmacological adherence (to diet, sun protection measures, physical activity, sexuality, hygiene, infection prevention, appointment-keeping, monitoring of own vital functions, and the performance of diagnostic tests) following organ transplantation should be measured at regular intervals. This can be carried out as part of transplantation-specific follow-up care, which is delivered at transplantation centers as well as by other outpatient and inpatient personnel. The frequency of this type of contact can vary significantly from person to person, explaining why no mention is made of a specific number of adherence measurements within a defined time period.
There are various different methods for assessing adherence. A simple way to measure adherence is by means of self-rating instruments. A number of validated questionnaires are available for this, either as self-(or third-party) rating instruments (diagnostic interview). To increase reliability, a combination of various measurement methods should be used (14, e8– e10) (table 1).
Table 1. Various methods for measuring adherence (adapted from Farmer [e27], [4]).
| Method | Advantages | Disadvantages |
| Blood level of medication | (Only) very recent use can be investigated | Only statements about very recent use arepossible and may be affected by other biological factors, individual kinetics |
| Observed medication use | Use can be verified | Virtually unfeasible in the outpatient setting |
| Patient interview | Easy to implement, no high costs | Interviewer requires an open and non-judgmentalattitude, socially desirable response behavior cannot be excluded |
| Patient diary | Self-reporting instrument providing informationon dealing with medication | An overestimation of adherence cannot be excluded;patient must keep the diary and bring it to their visit |
| Questionnaire to assess adherence | Easy to use, validated instruments(e.g., BAASIS, MARS), can provide an explanation for patient behavior | Snapshot, no continuous data; accuracy depends onthe instrument used |
| Tablet counting | Easy to use, no high costs | No information on punctuality of use; patient could forget doses or provide incorrect information |
| Checking the prescriptions filledfor seamless prescribing | Noninvasive method; if data are available inelectronic form, more straightforward evaluations across larger patient groups are also possible. This is generally not the case in Germany | The required information must be available or viewable |
| Electronic medication boxes/doses | Precise data on punctuality and regularity ofremoval from box | High costs, difficulties in implementation/handlingare possible, technical malfunction cannot be excluded, use not guaranteed |
Psychosocial interventions to improve adherence after organ transplantation
After reviewing the literature, the guideline group recommends with a high level of recommendation (A) and a high level of evidence (1) that, in the case of nonadherence, patients should be recommended an intervention, with multimodal interventions being the preferred approach (15– 18, e11– e17). The underlying rationale and suitable interventions are described below in more detail.
Since the literature search for the guideline, further meta-analyses across all organs have been published on the efficiency of interventions to improve adherence to immunosuppressant drug use following organ transplantation. These studies confirm the recommendation and are cited here.
Shi et al. (19) evaluated 27 articles up to December 2019 and Mellon et al. (20) evaluated 40 studies up to October 2021. Two studies were conducted in children and adolescents, 80% relating to patients following renal transplantation. The study interventions are heterogeneous, with the duration of interventions ranging between 2 and 12 months and the duration of follow-up history between 3 and 120 months. In overlapping studies, the evaluations of risk of bias differ significantly between the two meta-analyses. A variety of adherence outcomes are investigated:
Overall adherence (depending on the main outcome of the study)
Proportion of correctly taken medication doses (taking adherence)
Proportion of days on which medication dose is taken correctly (dosing adherence)
Proportion of medication doses taken at the correct time (timing adherence).
For overall adherence, the relative risk for a better outcome in the intervention group was 1.17 [1.07; 1.28] (19). Taking adherence did not differ significantly between treatment groups in either of the two meta-analyses, but days on which the drug dose was correctly taken certainly did (RR 1.21 [1.08; 1.29] [19] and RR 1.14 [1.03; 1.26] [20]). The positive effect of the intervention on taking the drug dose at the appropriate time was significant with low heterogeneity in Shi et al. (19) (RR 1.16 [1.03; 1.29], I2= 35%), whereas it did not differ significantly in Mellon et al. (20) (RR 1.10, [0.98; 1.23]). Subgroup analyses revealed that overall adherence could be improved both in renal transplant recipients (RR 1.23 [1.08; 1.41] and in patients receiving other organ transplants (RR 1.10 [1.0; 1.22], and that multidisciplinary interventions showed higher efficiency (RR 1.45 [1.25; 1.67], I2= 28%) compared to interventions by only one professional group (19). Another meta-analysis found no difference between eHealth interventions to improve adherence and treatment-as-usual (RR 1.10 [0.85; 1.41], seven studies) (21).
As a guide, the interventions can be classified into three categories (17, 18). Multicomponent interventions that are generally offered in a multidisciplinary setting and combine individual strategies from one or more of the following categories:
Cognitive/educational: imparting information and health-related knowledge
Behavioral: aimed at making concrete behavioral changes through measures such as planning, behavioral contracts, reminders, adherence monitoring, and feedback, etc.
Psychological/affective: focusing on emotional and social aspects, such as supportive treatment for affective stressors such as anxiety, depression, inclusion of the social environment, stress management, etc.
Overall, the heterogeneity of the study interventions, the outcomes, and their measurement, as well as the risk of bias of the individual studies, are high. Although some studies showed an improvement in adherence as a result of various interventions, a positive effect on prognosis in terms of event-free survival, 12-month mortality, or hospital admissions and their duration, has not yet been demonstrated in the available studies. On the other hand, neither was any harm as a result of the psychosocial interventions reported. Further research is needed here. Numerous other randomized studies aimed at improving adherence are currently underway (20).
Psychosocial risk factors for a poor prognosis after transplantation
Psychological comorbidity
Depressive disorders, anxiety disorders, adjustment disorders, acute stress reactions, and posttraumatic stress disorders are common among transplant patients, independent of the affected organ (2, 22, 23, e18– e20): Depressive disorders develop in, on average, 12–60% of patients prior to transplantation, independent of the affected organ. Following transplantation, prevalence rates of 13–40% are reported. Anxiety disorders are observed in, on average, 8–58% of patients before and in 17–60% after transplantation.
The presence of depression in transplantation patients is associated with higher overall mortality. In their meta-analysis, Dew et al. (2) conclude that, across all organs, the presence of depression increases the relative risk of mortality after transplantation by 65% (RR 1.65 [1.34; 2.05], 20 studies). The presence of an anxiety disorder did not significantly increase this risk (RR 1.39 [0.85; 2.27], six studies). The association is more pronounced in depression after compared to depression before transplantation (2, 12, 24– 26, e21).
Since this meta-analysis, other longitudinal individual studies, some with large patient groups, have been published. Lentine et al. (27) found that 1-year mortality was 39% higher (12.6% of a total of n = 72,054) (adjusted hazard ratio, aHR 1.39 [1.18; 1.64]) in patients that had used antidepressant medications before kidney transplantation. The use of antidepressants in the first year after transplantation was associated with a two-fold increase in mortality in the second year (aHR 1.94, [1.60; 2.35]). Smith et al. (28) reported that higher levels of depression were associated with higher mortality at 5 years post-lung transplantation (aHR 1.31, [1.06; 1.61], n = 132). Likewise, Rosenberger et al. (29) showed that there was a significantly higher risk of mortality in lung transplant patients diagnosed with depression (HR 1.65 [1.01; 2.71]. De la Rosa et al. (26) reported that patients with depression after heart transplantation had a significantly higher risk of 5-year-mortality (30% versus 9.5%, HR 3.57 [1.4; 9.3], n = 114).
The evidence on an increased risk of mortality after transplantation in the presence of depression is highly consistent and clinically relevant. Therefore, the likelihood of the presence of a mental health disorder should be assessed by means of screening questions in the patient history interview or standardized questionnaires at all stages of transplantation treatment. Depression should be treated according to the guidelines. To date, there are only sparse studies on the effect of treatment for depression on mortality following transplantation.
The two-question test is a suitable instrument to screen for the presence of current depression (30, e22):
During the past month, have you often been bothered by feeling down, depressed, or hopeless?
During the past month, have you often been bothered by little interest or pleasure in doing things?
Alcohol use
In a comparative approach, a number of meta-analyses have included patients following different organ transplants, with the number of studies after liver transplantation clearly predominating here (31, 32). Across all organs, the rate of alcohol use was calculated to be 23.6%, with 15.1% of transplant patients having at-risk drinking (32).
Alcoholic cirrhosis is one of the commonest indications for inclusion on the waiting list for a liver transplant (German Foundation for Organ Transplantation [Deutsche Stiftung Organtransplantation, DSO], Eurotransplant). Two recent meta-analyses described relapse rates for this group of between 22% (33) and 26.3% (34) following transplantation. In addition, Kodali et al. report annual relapse rates of 4.7% for any alcohol use and 2.9% for heavy alcohol use (34).
In the case of liver transplant patients with ethyl toxic cirrhosis, relapses following liver transplantation are associated with an increased risk of mortality. The relative chance of dying within 10 years of transplantation is 3.67 times [1.4; 9.5] higher compared to abstinent patients, with 19% of fatalities being attributable to continued alcohol use (34). Therefore, throughout the transplantation process, any alcohol use should be assessed, documented, and treated according to the guidelines in the case of high-risk, harmful, or dependent alcohol use (31– 34, e23– e25). To identify alcohol use, the Alcohol Use Disorder Identification Test (AUDIT) or the short version thereof, (AUDIT-C), are recommended. In patients with alcohol-related liver disease, the documentation of alcohol abstinence should be complemented by appropriate direct and indirect status markers (for example, ethyl glucuronide in urine, serum, or hair, phosphatidylethanol) (35).
Psychosocial evaluation
Due to the frequency and impact of nonadherence and mental health comorbidity, the guideline group recommends that all patients on the waiting list for organ transplantation should undergo a psychosocial evaluation carried out by an MHP. Ideally, it would be obligatory for an MHP to participate in the interdisciplinary transplantation conference for all organ groups. In the current guidelines of the German Medical Association (Bundesärztekammer) on waiting list management for liver and lung transplantation, provision is already made for an MHP as a mandatory participant with voting rights in the transplant conference.
The psychosocial evaluation should provide information in particular on previous and current mental health disorders and psychosocial stressors, use of psychoactive substances, as well as the patient’s individual and social resources (36– 38). The psychosocial evaluation should be carried out in a systematic manner in the form of a clinical diagnostic (semistructured [e26]) interview. Possible critical results are listed in Table 2.
Critical results from the psychosocial evaluation, such as the presence of a manifest mental health disorder, should not as a matter of course be seen as a criterion for exclusion from the transplantation waiting list. Instead, in such cases, the indication for a psychosocial intervention needs to be assessed. The aim of the intervention should be to sufficiently stabilize the individual for placement on the list and for the transplantation process. This is successful in many cases. It is not possible to make a universally valid recommendation regarding the exclusion of a patient from the transplantation list due to a mental health disorder. Rather, a decision of this kind needs to be very carefully considered on a case-by-case basis.
