Abstract
Purpose:
Approaching death seems to be associated with physiological/spiritual changes. Trajectories including the physical–psychological–social–spiritual dimension have indicated a terminal drop. Existential suffering or deathbed visions describe complex phenomena. However, interrelationships between different constituent factors (e.g., fear and pain, spiritual experiences and altered consciousness) are largely unknown. We lack deeper understanding of patients’ inner processes to which care should respond. In this study, we hypothesized that fear/pain/denial would happen simultaneously and be associated with a transformation of perception from ego-based (pre-transition) to ego-distant perception/consciousness (post-transition) and that spiritual (transcendental) experiences would primarily occur in periods of calmness and post-transition. Parameters for observing transformation of perception (pre-transition, transition itself, and post-transition) were patients’ altered awareness of time/space/body and patients’ altered social connectedness.
Method:
Two interdisciplinary teams observed 80 dying patients with cancer in palliative units at 2 Swiss cantonal hospitals. We applied participant observation based on semistructured observation protocols, supplemented by the list of analgesic and psychotropic medication. Descriptive statistical analysis and Interpretative Phenomenological Analysis (IPA) were combined. International interdisciplinary experts supported the analysis.
Results:
Most patients showed at least fear and pain once. Many seemed to have spiritual experiences and to undergo a transformation of perception only partly depending on medication. Line graphs representatively illustrate associations between fear/pain/denial/spiritual experiences and a transformation of perception. No trajectory displayed uninterrupted distress. Many patients seemed to die in peace. Previous near-death or spiritual/mystical experiences may facilitate the dying process.
Conclusion:
Approaching death seems not only characterized by periods of distress but even more by states beyond fear/pain/denial.

Introduction
End-of-life processes seem to be associated with essential physiological changes 1,2 and spiritual transformations. 3,4 Trajectories including the physical–psychological–social–spiritual dimension have indicated a “terminal drop” 5 –7 —a sharp and abrupt physiological/psychological/spiritual deterioration. Nevertheless, we lack detailed information about shifting states of distress and peace. Complex phenomena are described as existential suffering, 5 –11 but interrelationships between constituent factors (e.g., fear and pain) are largely unknown. We lack deeper understanding of patients’ inner processes to which care should respond. 3,5,7,12,13
Study results confirmed spirituality 14 as helpful in dealing with distress and improving quality of life 15 –17 even amid severe illness. 18 Single spiritual phenomena such as “spiritual distress” were identified. 19 –21 Deathbed phenomena were often associated with spiritual experiences and a peaceful death. 22 –30 However, we do neither know when nor why spirituality becomes fundamental during dying processes (immediately before death, amid calmness, or struggle) and if spiritual experiences are linked to religious beliefs.
Studies on near-death experiences (NDEs) have provided accounts of deep spiritual experiences. 31 –34 They alter attitudes to religion, to life, and decrease fear of death. 34,35 But no studies dealt with impacts of previous NDEs on dying processes although described emotions, and visionary image sequences in NDEs may also emerge at the end of life. 3,4,36,37 The authors’ preliminary study (Dying a Transition, N = 680) suggested that a transformation of perception involving an alteration in consciousness comparable to those in NDEs underlays the dying process. 3,38 Patients lose their everyday consciousness and ego-related perception and enter into a completely new, ego-distant mode of perception, which seemed accompanied by less or no fear/struggle/denial and with changes in family relationships. The study listed 3 phenomenologically distinct stages: pre-transition, transition itself, and post-transition. In pre-transition, patients still had their everyday consciousness but were approaching death: Emotions, family processes, and maturation were intensified. In transition itself, even consciousness and perception was changing: Sensitivity, distress, and fear often culminated. In post-transition, perception was no longer bound to the ego, for example, patients signalized a state beyond time (timeless), beyond space (endless/nonlocal), 32,33 or beyond our normal sense of gravity (out-of-body experience), and without ego-related emotions and impulses (e.g., needs, hunger, fear, and denial). 3,38 These states may be comparable to prenatal, perinatal, and postnatal experiences 39 but happen several times. However, the preliminary study did not include pain and was based on therapy records written by only one therapist/spiritual caregiver.
Methods
In this mixed-method exploratory observational study, 80 dying patients with cancer were observed by two nursing teams and at least one physician, psychotherapist, and spiritual caregiver in each team. Professionals had different religious/spiritual attitudes. The sample size corresponded to our former pilot study and to guidelines of Interpretative Phenomenological Analysis (IPA). 38,40 In both centers, around half of all team members attended a 2-day voluntary workshop offered by a psychotherapist and a physician. Issues covered results of the previous study, interpretation of symbols in folktales/dreams and symbolic communication, discussions of practical case vignettes, and music-mediated relaxation to possibly enhance sensitivity to an altered awareness of time/space/body. The other professionals underwent a half-day training. All professionals could ask the psychotherapist for support at the deathbed. Then, they were introduced into method (participant observation) and tools.
We used a semistructured observation protocol (O-Protocol) designed by the core study team (psychotherapist, nurse, physician), reviewed for face and construct validity by several professionals of each team. It entailed
Inclusion and observation began when patients were diagnosed by the treating physician as dying within 3 days up to 1 or 2 weeks (no specific prognostication tool applied). Excluded were patients unable to answer the questions during the routine admission conversation, patients with psychosis and dementia, and patients who died within 2 days after starting observation or left the hospital during data collection. Patients were observed daily: At midday shift change, two care professionals independently recorded their observations of the same patient situation. After each marked change in patients’ conditions, professionals additionally conducted observations up to 8 times per day. Professionals were encouraged to ask mutually complementary questions to allow patients reacting to one question or the other. Concerning spiritual experiences, they had to focus on obvious signals (e.g., verbal hints about angels). After observation, professionals filled out the O-Protocol. In informal round table sessions, the interdisciplinary team reflected topics from the O-Protocol, but no adaptations of the procedures were made. After death, the data were anonymized and entered into the database. From the medical chart, the list of analgesic and psychotropic drugs was added.
Analysis
Descriptive statistical method was combined with IPA. 40 Two researchers with a different professional background (psychotherapist and nurse) analyzed the data and consulted in case of doubt a third person (physician). An international panel (co-authors and experts in philosophy, theology, and NDE) discussed the analysis plan, preliminary results, subgroups, and open questions. Then, the core study team conducted the analysis.
First, the observation data were visualized

Results
Of the 80 participants 40 were men and 40 women. The average age was 62 years (range 30-90 years). In all, 65 (81.3%) were Christian and 63 (78.8%) called themselves religious/spiritual (Table 1). Our study yielded 2084 O-Protocols in 2 years’ time (site 1: 1005; site 2: 1079). We had 526 double observations (n =1052; 50.5% O-Protocols).

Fear/Pain/Denial/Spiritual Experiences
Most patients showed fear (75; 93.8%; 625 O-Protocols), pain (75; 93.8%; 706 O-Protocols), and spiritual experiences (72; 90%; 550 O-Protocols) at least once; 42 (52.5%) underwent denial (565 O-Protocols). Among patients with fear, 50 (62.5%) signalized fear also at time of admission, 25 (31.3%) did not. Among patients with spiritual experiences, 60 (75%) were Christians, 9 (11.3%) patients were without religious affiliation, 1 Buddhist, 1 Muslim, and 1 was adherent of natural religion (Tables 2 and 3).

Associations Between Erupting/Subsiding Distress and Transformation of Perception (Comparison of Both Graphs)
In 6 (7.5%) patients, associations were perfect and in 34 (42.5%) clearly visible (e.g., Figure 1: No 1). Transition itself seemed to be related to distress (Figure 2): Out of 528 O-Protocols stating transition itself, 348 (65.9%) indicated fear. Vice versa, of 625 O-Protocols indicating fear, 348 (65.9%) documented transition itself. Pre-transition and in particular post-transition showed associations with peace and spiritual experiences (Figure 2): For example, of 559 O-Protocols stating post-transition, 516 (92.3%) indicated no fear, and 248 (44.4%) reported spiritual experiences.

Interpretation of Suffering, of Peaceful Death and Facilitating/Hindering Factors
Many patients (20; 25%) died in/after 1 to 5 days of peace and 22 (27.5%) after 6 to 24 hours of peace. In all, 14 (17.5%) died amid distress; nevertheless, 8 of them had long periods of peace before (Figure 1: No 20). At the last observation, 65 (81.3%) patients were in post-transition and 9 (11.3%) in transition itself. Interpretation of suffering ranges from “no/almost no suffering” (10; 12.5%), “mild suffering” (39; 48.8%), “moderate suffering” (11; 13.8%), periods of much suffering along with calm periods (16; 20%; Figure 1: No 20; No 119) to “much suffering” (4; 5%). No patient suffered moderately or severely for longer than 2 days. (Table 5; Figure 3)

Suffering and facilitating/hindering factors.
Among patients with “no/almost no” or “mild suffering” (49; 61.3%) were many with previous NDEs or spiritual/mystical experiences. Three out of 9 patients with a previous NDE had “no/almost no suffering” (Figure 1: No 180). Concerning attitudes, coping strategies, and spiritual practices—particularly “curiosity about afterlife”—had a positive, repressing almost no impact.
Discussion
In dying processes, fear/pain/denial seem to be highly associated (peaks of concurrence) but not lasting: Without exception, distress was followed by periods/incidences of observed peace. Observed calmness can last for days (Figure 1: No 1; No 119; No 180). Although pain was reported in other studies to be prevalent at the end of life in 66.4% 44 and 70% to 90% 45 of patients with cancer, our graphs modify the notion of a “terminal drop” phenomenon 5 –7 and of increasing suffering before death.
Hindering and Facilitating Factors
Christians, adherents of other religions, and nonreligious patients had to endure suffering and death-related anxiety; this reportedly frequent challenge 3,47,48 overwhelmed 75 (93.8%) patients, also 25 from a total of 27 who had no fear at time of admission. According to King et al, religious/spiritual attitudes do not predict later levels of anxiety or depression. 49
However, deep positive experiences, previous NDEs, and mystical/spiritual experiences as well as open-mindedness (curiosity about afterlife) seemed to reduce suffering. As reported,
30,36
patients with a belief in afterlife experienced comforting deathbed phenomena, although they may experience greater anxiety than those without this tenet of belief.
50
The point may be that
In contrast, repressing did not affect the level of suffering: Sometimes it seemed to aggravate the process, sometimes it was helpful. Rousseau pointed out that denial as coping strategy may be beneficial and support patients in dealing with unfinished business but may also block a peaceful dying process. 53 Other studies reported that patients who accepted their prognosis suffered less from severe anxiety and depressive symptoms. 54,55 No fear of death seemed to be only slightly beneficial. It could indicate deep trust in 3 (11.1%) of 27 patients but also repression in 6 (22.2%). In all, dying processes remain unpredictable.
Limitations
Our data were limited to patients with cancer from Eastern Switzerland. Due to our homogeneous sample, we considered religious affiliation only in analyzing spiritual experiences (Table 3). Application of our findings to patients of other cultural background and diseases has to be done with caution. Between observation times were unrecorded periods, despite 2 to 8 daily observations. Observations were subjective evaluations and influenced by staff culture and interventions. However, the huge amount of prospective data (2084 O-Protocols), the fact of two sites, and of two independent observations (526 times, 1052 O-Protocols, 50.5%) offer reliability to the data set. The median of Cohen’s Kappa
56
shows substantial agreement in interrater reliability ranging between 0.57 (altered awareness of time/space/body) and 0.71 (denial), 0.65 for spiritual experience, 0.66 for social connectedness, 0.67 for fear, and 0.68 for pain. Further, we marked positive reactions that were possibly influenced by care and therapeutical interventions with asterisks so that, for example, The observation of spiritual experiences in particular could be biased by the attitude of the observer and may explain different results between the two sites (Table 2). However, double observations during mid-day shift (N = 526) showed little deviation (degree 1: for spiritual experience 14.3% of O-Protocols; for fear/pain/denial 10.8%). Subgroups and interpretation of suffering were found only by consensus and not by predefined criteria. The assignment of the subgroup “pre-transition/post-transition” to pre-transition in particular has to be considered. However, required consensus by researchers of different professional background and many qualitative notes minimized researcher bias. Periods of peace and post-transition may be medication-induced. These important objections can be refuted in many cases after careful study of medication (Table 4). The phenomenon seems to happen often naturally/spontaneously as part of the dying process.
Clinical Relevance
Results and line graphs can alleviate fear of a “terminal drop” (sharp and abrupt physiological/psychological/spiritual deterioration) in patients, relatives, and the public. An understanding of transition
3,38
and our findings combined with respect for every individual patient and process may improve care and instill confidence for recurrent states without/“beyond” fear/pain/denial. Relatives can better understand the “remoteness” and signals of their loved ones. The parameters (space/time/body awareness and social connectedness) for assessing transitional stages may be explored in further research. We noted high benefit for individual care interventions. The concept of transition may help offer non-pharmocological support and an alternative to unspecific sedation for many patients.
