Abstract
Background
We investigated the need for additional professional support and associated factors in patients (pts) at initiation and in the course of in- and outpatient specialist palliative care (I-SPC/O-SPC).
Methods
Pts entering an urban SPC network consecutively completed questionnaires on psychosocial/spiritual problems and support needs within 72 h (T0) as well as within the first 6 weeks (T1) of SPC. Hierarchical linear regression analysis was used to investigate the impact of sociodemographic / disease-related variables, psychological / physical burden, social support, and SPC setting on the extent of support needs.
Results
Four hundred twenty-five pts (70 years, 48% female, 91% cancer, 67% O-SPC) answered at T0, and 167 at T1. At T0, main problems related to transportation, usual activities, and dependency (83–89%). At T1, most prevalent problems also related to transportation and usual activities and additionally to light housework (82–86%). At T0, support needs were highest for transportation, light housework, and usual activities (35–41%). Cross-sectional comparisons of SPC settings revealed higher problem scores in O-SPC compared to I-SPC at T0 (p = .039), but not at T1. Support need scores were higher in O-SPC at T0 (p < .001), but lower at T1 (p = .039). Longitudinal analyses showed a decrease of support need scores over time, independent from the SPC setting. At T0, higher distress (p = .047), anxiety/depression (p < .001), physical symptom burden (p < .001) and I-SPC (p < .001) were associated with higher support need scores (at T1: only higher distress, p = .037).
Conclusion
Need for additional professional psychosocial/spiritual support was identified in up to 40% of pts. with higher need at the beginning of O-SPC than of I-SPC. During SPC, this need decreased in both settings, but got lower in O-SPC than in I-SPC over time. Support need scores were not only associated with psychological, but also physical burden.

Background
Palliative care aims to address complex problems and needs of patients including physical, psycho-spiritual, and socio-cultural aspects [1]. For cancer patients, still representing the major patient group receiving palliative care in Western countries, professional support in coping with tasks, accepting the disease, generating strength, feeling trust, strengthening the sense of control and other psychosocial and spiritual needs is considered as part of standard patient care [2, 3]. However, international experts complain that “the multiple and varying needs of patients are still not being met adequately as part of routine cancer care” [4]. Various studies underline this complaint, demonstrating high proportions of unmet needs (50–90%) in patients with cancers across all stages and during the whole disease trajectory [5–8]. It has also been shown that non-cancer patients present with similar main needs compared to a matched cohort of cancer patients, although there were some differences in quality, but not quantity of physical symptom burden [9].
Clinical studies showed that timely inclusion of specialist palliative care (SPC) can not only improve quality of life or symptom burden, but is also associated with a better addressing of patients’ needs, especially concerning information and care planning [10]. Psychosocial and spiritual interventions can successfully meet the complex psychosocial and spiritual needs of patients with advanced diseases [11–14].
SPC is offered in inpatient (I-SPC) and outpatient settings (O-SPC). Usually, the SPC setting is chosen according to patients’ individual wishes and needs. However, there are various factors reducing the probability that an outpatient care setting can address the patients’ needs adequately, e.g. patients living alone at home without any family caregivers [15], patients’ age or multi-morbidity [16]. In Germany, I-SPC was established as a billable service in 2005, and O-SPC has become prescribable by law in 2007 [17]. In contrast to the multi-professional principles of SPC in general and to the setting of I-SPC, O-SPC only comprises bi-professional care by specialized physicians and nurses, because the services of other professions such as psychologists or therapists are not covered by health insurance [7, 18]. This contrast becomes particularly manifest when patients are discharged to home care when the psychological and psycho-oncological care is interrupted [7, 19]. In daily practice, voluntary hospice workers often provide home-based psychosocial and spiritual care, while inclusion of professional support is rare and heterogeneous. This might indicate a possible care deficit, especially because up to 50% of terminally ill patients in home settings suffer from mental disorders [20].
The urban area of Hamburg was the first region in Germany that had established a complete and comprehensive network of I-SPC and O-SPC. Therefore, Hamburg can be regarded as a prime example for multi-institutional SPC networks. In this setting it is promising to evaluate if such a comprehensive SPC network can adequately address the complex problems and needs of patients with advanced diseases and terminal illnesses.
The main aim of the present study was to explore problems related to psychosocial and spiritual problems of patients at initiation and during SPC and to identify their need for additional professional support in these domains. Secondary aims concerned possible differences between patients entering I-SPC versus O-SPC. Further, we investigated the impact of sociodemographic and disease-related variables, physical symptom burden, distress, anxiety/depression and SPC setting on the extent of patients’ need for additional professional support.
Methods
This prospective, observational longitudinal multicenter study was carried out in Hamburg, Germany. In a 12 months’ period between June 2017 and July 2018, patients were consecutively enrolled in six SPC services of an urban network, including three SPC home care services (O-SPC) and three SPC wards (I-SPC). Within 72 h after first admission, patients were recruited by trained staff of the services.
Inclusion criteria were being older than 18 years, suffering from an advanced, life-limiting illness (cancer and non-cancer), and entering in- or outpatient SPC for the first time. The participating centers cared mainly for patients with advanced cancer resulting in an expectable underrepresentation of non-cancer patients. However, these patients represent a typical cohort during SPC in Europe where up to 90% of SPC patients suffer from oncological diseases [21]. Previous studies also suggest that the problems and needs are similar between cancer and non-cancer patients [9, 22]. However, two studies comparing cancer and non-cancer patients, suggest that non-cancer patients present with lower functional status when first entering SPC [22, 23]. Exclusion criteria were cognitive or language problems hampering informed consent and/or answering questionnaires, acute physical or psychological crisis entailing the risk that study participation would significantly increase patients’ burden, and patients’ imminent death. Reasons for study exclusion or non-participation were systematically documented.
Self-report questionnaires were used for data collection, which were handed out personally by staff of the SPC services. Patients’ assistance for answering questionnaires was allowed upon request. Baseline data (T0) were collected within 72 h after admission to gain information about the patients’ situation at initiation of SPC. Follow-up measurements were scheduled as follows: As long as patients stayed in the same SPC service, questionnaires were administered every 4 weeks during ongoing SPC. Additionally, patients received a questionnaire before being transitioned to other SPC services or to non-SPC settings. The first questionnaire returned during the first 6 weeks of SPC served as follow-up (T1). Beyond this timeframe, further follow-ups were assessed according to the study protocol, but were not included in the current analysis due to limited sample sizes.
The ethical committee of the General Medical Council of Hamburg has approved the study protocol (PV5062). Written informed consent was obtained before study participation.
Measurements
Outcome measure
Problems and needs for additional professional support were measured by an adapted version of the Problems and Needs in Palliative Care Questionnaire – Short Version (PNPCQ-sv) [24, 25]. With permission of its authors, the questionnaire was professionally translated to German language, and comprehensibility was tested in a small convenience sample. In order to focus on psychosocial and spiritual issues, the adapted version omitted physical symptoms. The included 22 items comprised aspects of daily activities, autonomy, need of information, and social, psychological, spiritual and financial issues, which were considered as psychosocial and spiritual issues in the broadest sense.
Two independent sum scores were calculated: the “Extent of psychosocial and spiritual problems” score (short: problem score) and the “Extent of need for additional professional support” (short: support needs score). Each score ranges from 0 to 22 with higher values reflecting a higher number of problems or support needs. Scores for respondents with ≤4 missing items were calculated by imputing the mean score for the missing items based on items completed by that individual. In case of > 4 items (20%), a score was not calculated for that individual. Respondents for which the problem score was not calculated were 9 (2.1%) at T0, and 3 (1.8%) at T1. Likewise, the support needs score was not calculated for 80 respondents (18.8%) at T0 and 27 (16.2%) at T1.
Potential predictor variables
The distress thermometer (DT) was used to assess psychological distress within the last week on an 11-point analogue scale. Clinically relevant distress with need of professional psychological support is indicated by a cut-off value of ≥5 [26, 27]. The DT includes a problem list with 21 physical symptoms that can be classified to contribute to psychological distress or not. We used the sum score of distressing physical symptoms (“physical symptom count”, 0–21) to estimate the range of patients’ physical symptoms (see supplemental material 1).
The PHQ-4 including a two-item depression scale (PHQ-2), and a two-item anxiety scale (GAD-2) was used for measurement of depressive and anxiety symptoms [28].
In addition, patients reported on sociodemographic characteristics (i.e. age, marital status, educational level, living environment), as well as disease-related data (i.e. primary disease, previous nursing situation).
Statistical analyses
We performed descriptive analyses to examine study population characteristics and to describe patients’ psychosocial and spiritual problems and their need for additional professional support.
Data of patients admitted to I-SCP vs. O-SPC at initiation of SPC (T0) and at follow-up during SPC (T1) were compared cross-sectional using chi-square-tests (Fisher’s exact test if expected values in any cell were below 5) and two-sample t-tests (two-tailed).
The problem scores and support need score at T0 were compared with the respective scores at T1 using repeated measures ANOVA (RM-ANOVA) with setting (O-SPC vs. I-SPC) as a main factor. As measures of effect, we calculated partial eta-squared (ŋp2; small = 0.01, medium = 0.06, large = 0.14).
Two hierarchical linear regression models (enter method) were used to investigate the impact of sociodemographic and disease-related variables, psychological and physical burden, and SPC setting on the extent of patients’ need for additional support. Support needs scores at T0 and at T1 were defined as dependent variables, respectively. Sociodemographic variables were added in step 1 (Model 1), disease-related variables at step 2 (Model 2), proxy-variables for social support at step 3 (Model 3), physical burden at step 4 (Model 4), and variables reflecting psychological burden at step 5 (Model 5). Categorical predictor variables were dichotomized. Examination of correlations among the predictor variables revealed no problems with multicollinearity. Missing data were handled using the list wise deletion method.
All significance tests were two-tailed using a significance level of α < .05. Analyses were completed using SPSS software version 25.0 (IBM, 2017).
Results
Patient recruitment and characteristics
During recruitment, 1713 patients were admitted to the six participating services. Of these, 713 (42%) were eligible for study inclusion, and 443 were willing to participate (61%). Among 425 who returned the baseline questionnaires (T0), 285 were admitted to O-SPC (67%) and 140 to I-SPC (33%). At follow-up during SPC (T1), 167 patients (39%) answered a questionnaire. At this time point, 130 (78%) were treated in O-SCP and 37 (22%) in I-SPC (Fig. 1).
Fig. 1.
Recruitment process and patient cohort development
Overall, at initiation of SPC (T0) 52% of 425 patients were male (mean age 69.7 ± 12.5 years) and 91% suffered from cancer. Patients admitted to O-SPC were significantly younger (p < .001) and had needed less intensive nursing prior to SPC (p = .008) than in I-SPC (Table 1).

Cross-sectional analyses of problems at initiation and during SPC
At initiation of SPC (T0), the five most prevalent problems were “transportation” (88.9%), “difficulties in continuing the usual activities” (88.9%), “being dependent of others” (82.6%), “doing light housework” (82.1%), and “body care, washing, dressing or toilet” (70.4%). Problems in the psychological and spiritual domains were reported less often, but were still indicated by 44 to 69% (psychological issues) and 45 to 55% (spiritual issues) of patients. A significant difference between the O-SPC and I-SPC group was observed in six of 22 given problems. Except for one aspect, these problems were more frequent in O-SPC, resulting in a higher mean problem score in the O-SPC vs. I-SCP group (11.7 vs. 11.1, p = .039).
During SPC (T1), the five most common problems were “transportation” (85.5%), “difficulties in continuing the usual activities” (85.3%), “doing light housework” (81.7%), “difficulty coping with the unpredictability of the future” (67.3%), and “body care, washing, dressing or toilet” (67.1%). Again, psychological (39 to 67%) and spiritual problems (37 to 58%) were indicated less often. Problem scores did not differ significantly between patients receiving O-SPC vs. I-SPC at this point of time (p = .278.). However, patients receiving I-SPC more often reported problems regarding “transportation” (p = .049) and “finding others not receptive to talking about the disease” (p = .003, Table 2).

Cross-sectional analyses of need for additional professional support at initiation and during SPC
At T0, the five most common needs for additional professional support were “transportation” (40.5%), “doing light housework” (38.4%), “difficulties in continuing the usual activities” (35.2%), “difficulty coping with the unpredictability of the future” (29.9%), and “being dependent of others” (28.9%). Need for additional professional support was indicated by 15.3 to 29.9% of patients concerning psychological problems, and 18.4 to 24.7% concerning spiritual problems. A significant difference between the O-SPC and I-SPC group was observed in nine of 22 given needs, including all spiritual aspects. These needs were consistently more prevalent in O-SPC compared to I-SPC. Additionally, the mean needs score showed to be significantly higher in patients receiving O-SPC (6.4 vs. 4.1; p < .001).
At T1, need for additional professional support had decreased in most aspects. Among 167 patients, the five most frequent needs for more support related to “transportation” (24.0%), “doing light housework” (19.9%), “being dependent of others” (19.7%), “difficulties in continuing the usual activities” (19.6%), and “difficulty coping with the unpredictability of the future” (13.2%). Need for additional support was reported by 3.2 to 13.2% of patients for psychological problems, and by 9.0 to 11.8% for spiritual problems. During SPC (T1), the mean support need score was significantly lower in O-SPC compared to I-SPC (1.7 vs 3.2; p = .038). At the level of single needs, “difficulties to accept the disease” was experienced differently across SPC settings with patients in O-SPC reporting less need for support (7.0% vs. 18.9%, p = .034; Table 3).

Longitudinal analyses of problems and need for additional professional support
Comparing problem scores at T0 with T1, no significant effects were detected by RM-ANOVA. Analyzing the course of the support needs scores, significant improvement could be demonstrated over time (large time effect: p < .001, ŋp2 = .106), meaning that less needs were reported to be unmet. However, we found no significant effects of the setting (O-SPC/I-SPC) or interaction effects of time and setting (Table 4).

Potential predictors for additional professional psychosocial or spiritual support needs at initiation and during SPC
Predictors for the extent of support needs at both time points were identified by hierarchical linear regression analyses.
At T0, variables of step 1 to 3 (sociodemographic, disease-related, and proxy-variables for social support) only explained up to 5% of the variance in the support needs score, and SPC setting showed to be the single predictor. Physical burden, tested in step 4, explained an additional 25% of variance. Psychological factors, tested in step 5, explained an additional 10% of variance. Higher distress (p = .047) and higher level of anxiety/depressive symptoms (p < .001) were associated with the support needs score. Additionally, SPC setting (p < .001) and physical burden (p < .001) remained significantly associated in this final model.
At T1, variables tested in step 1 to 3 only explained up to 8% of the variance with primary disease being the only significant predictor. Physical burden, tested in step 4, explained an additional 4% of variance. Psychological factors, tested in step 5, explained an additional 7% of variance when controlling the other factors. Higher distress (p = .037) was associated with the support needs score, and neither of the other factors remained significantly associated in the final model (Table 5).

Discussion
This prospective longitudinal study evaluated psychosocial and spiritual problems of patients receiving I-SPC or O-SPC, their need for additional professional psychosocial and spiritual support and predictors for a higher number of support needs.
Psychosocial and spiritual problems
The most prevalent problems of patients at initiation of SPC were problems in the dimension of daily activities. During SPC, four of the five most frequent problems were still related to daily activities. However, with “difficulty coping with the unpredictability of the future” as fourth frequent problem, a psychological aspect gained on impact. In line, in a previous German study patients receiving O-SPC most commonly reported problems concerning daily activities (fatigue, getting around, eating, bathing/dressing) [29]. The impact of such impairments is also emphasized by a study reporting that problems in the area of functioning were most frequently complained by patients receiving SPC [30]. In our study, spiritual problems were less frequently identified than psychological problems, but still concerned about 40% of patients at both assessments. This matches with previous studies reporting an importance of spirituality / spiritual aspects during palliative care in about 30–40% of patients [31].
Comparing O-SPC and I-SPC, problems tended to be more frequent in the O-SPC group at initiation of SPC, which also reflected in significantly higher problem scores. Despite these differences, patients from both settings showed relevant problems requiring multi-professional care. In contrast, the setting did not influence problem scores at follow-up during SPC; however, prevalence of two single problems (“transportation”, “finding others not receptive to talking about the disease”) was significantly higher in the I-SPC group. In a retrospective study comparing O-SPC and I-SPC, O-SPC patients had worse function and higher need for care planning and family support [31, 32].
Longitudinal analyses of problem scores showed no significant effects of time and setting. This might not be surprising as the patients’ advanced diseases progress over time, and SPC could only maintain stability of symptoms and problem burden.
Need for additional professional psychosocial and spiritual support
The need for additional support was lower than the extent of the corresponding problems at both assessments indicating that patients might not expect or want professional support for every problem they perceive, especially regarding psychological and spiritual problems. While some patients require deeper psychological and spiritual support (ranging from approximately 10 to 40%), others might prefer to cope with such problems themselves. Additionally, some problems might be addressed by informal support, e.g. family caregivers, or patients might not be able to feel and express their need for additional professional support.
Reviewing the relative prevalence of needs reported in our study, need for additional support related to daily activities was most common both at initiation and during SPC: At initiation of SPC, the three most common needs for additional support concerned daily activities, followed by two psychological issues regarding the difficulty to cope with the unpredictability of the future and being dependent of others. During SPC, the need for additional support decreased in most aspects with the same needs representing the “top five”. Literature on patients’ support needs mainly relates on cancer patients [8, 30, 33–42]. These studies also demonstrate that daily living, practical support, information and emotional/psychological support consistently represent the most prevalent unmet support needs [8, 30, 33–42]. In line with the results from our study, a repeatedly mentioned psychological problem causing support need is the unpredictably of future [8, 38, 41].Additional need for professional spiritual support was lower with about 20% at initiation of SPC and about 10% during follow-up indicating that such support is required by a subgroup of patients. However, studies strengthen the lack of spiritual support even during SPC in a still relevant number of patients [9].
These findings are both understandable and consistent with Maslow’s hierarchy of needs theory [43]. Maslow’s hierarchy of needs divides human needs in five categories from low to high (like a pyramid), starting with basic physiological demands. The theory proposes that if needs of a certain level are satisfied, the next higher need emerges and the pursuit of a higher level of needs becomes the driving force for behavior. In our study, the highest needs for additional professional support related to the more basic needs, like daily activities and transportation, which may have to be met for patients to feel safe enough to attend to psychological and spiritual needs. However, our findings also indicated that higher needs may already be important although lower-level may have not been met. Despite the usefulness of this theory for assessing patients’ needs in palliative care, the criticism that Maslow’s ranking of needs might be overly simplistic has to be kept in mind [44].
Comparing SPC settings, patients scored significantly higher additional support need when entering O-SPC. Interestingly, during SPC, the need for additional psychosocial and spiritual support was higher in I-SPC. However, higher support needs during inpatient compared to outpatient care in cancer patients have been demonstrated [33].
Longitudinal analyses of patients’ need for additional support showed a significant improvement over time, but without any difference between the two SPC settings. This result indicates that the two different SPC settings satisfy the needs of the referred patient cohorts, which strengthens the results of a previous study demonstrating that SPC could meet the needs of their target group [39].
Factors associated with additional professional support needs
At initiation of SPC, higher support need scores were associated with higher physical symptom burden, higher distress, higher levels of anxiety/depression and I-SPC setting. In contrast, during SPC, higher distress revealed to be the only predictor of support needs. Previous studies have also reported significant effects of distress and problem or symptom burden on patients’ support needs [29]. In our study, sociodemographic or disease-related factors were not identified to be predictive, which is in line with previous studies that could not find any or only partial associations between sociodemographic or medical/disease-related factors in patients with advanced diseases [29, 38, 40]. Only one study including older cancer patients observed that non-white, divorced or never married patients had higher unmet social support needs [39].
Strengths and limitations
This study has some strengths, e.g. the prospective longitudinal design, consecutive patient recruitment within an established SPC network, and systematic documentation of non-response. In addition, our study specifically evaluates the need for professional support in patients receiving SPC. Previous study mainly analyzed “unmet needs” which does not clarify if the patients expect professional or non-professional support, e.g. from family caregivers.
However, there are some limitations that have to be noticed. Our SPC network is located in an urban region and it remains unclear if these results could be transferred to patients in more rural areas.
We included aspects of daily living as psychosocial aspects when using the PNPC-sv, while some other questionnaires define them as a separate or physical category. However, the PNPC-sv is one of the two most commonly used questionnaire in needs assessment at least in cancer patients [36]. Overall, the different questionnaires used for needs assessment hamper comparability of data in general [35, 36].
In conclusion, a relevant number of problems, mainly concerning limited daily activities, should be considered in patients entering SPC. Psychological and spiritual problems could be expected more frequently in patients entering O-SPC, but this difference will be balanced during SPC, indicating that SPC services can meet professional care for basic needs, but also for higher-level needs, like psychological and spiritual needs. However, healthcare professionals should respect that patients do not expect or want professional support for all of their problems. In daily routine care, assessments should be used that allow to distinguish between problems and (unmet) needs, which are two different concepts. Patients requests for additional professional support mainly concern aspects of daily living, dependency and coping with the unpredictability of the future. Spiritual problems and need for additional professional support are less frequent than psychological. Patients’ need for additional support decreases during SPC, but does not show any difference between the two SPC settings. Patients’ support needs are associated with psychological distress and physical symptom burden, but not sociodemographic or disease-related factors.
