Specialized home palliative care for adults and children: differences and similarities

OBJECTIVE

To compare the provision of specialized home palliative care (SHPC) by the adult and pediatric SHPC teams at the Munich University Hospital.

METHODS

All patients treated by one of the SHPC teams and their primary caregivers were eligible for the prospective nonrandomized survey. We analyzed the demographics, the underlying diseases, duration and impact of SHPC on symptom control and quality of life (QOL) as well as the caregivers' burden and QOL.

RESULTS

Between April 2011 and June 2012, 100 adult and 43 pediatric patients were treated consecutively; 60 adults (median age, 67.5 years; 55% male) and 40 children (median age, 6 years, 57% male) were included in the study. Oncologic diseases were dominant only in the adult cohort (87 versus 25%, p<0.001). The median period of care was higher in the pediatric sample (11.8 versus 4.3 weeks; NS). Ninety-five percent of adult and 45% of pediatric patients died by the end of the study (p<0.001), 75% and 90% of them at home, respectively. The numbers of significant others directly affected by the patient's disease was higher in children (mean 3.4 versus 1.2; p<0.001). The QOL of adult patients and children (p<0.05 for both), as well as of their primary caregivers (p<0.001 for both) improved during SHPC, while the caregivers' burden was lowered (p<0.001 for both).

CONCLUSIONS

Our results show important differences in several clinically relevant parameters between adults and children receiving SHPC. This should assist in the development of age-group specific SHPC concepts that effectively address the specific needs of each patient population.

Specialized pediatric palliative home care: a prospective evaluation

OBJECTIVES

In Germany since 2007 children with advanced life-limiting diseases are eligible for Pediatric Palliative Home Care (PPHC), which is provided by newly established specialized PPHC teams. The objective of this study was to evaluate the acceptance and effectiveness of PPHC as perceived by the parents.

METHODS

Parents of children treated by the PPHC team based at the Munich University Hospital were eligible for this prospective nonrandomized study. The main topics of the two surveys (before and after involvement of the PPHC team) were the assessment of symptom control and quality of life (QoL) in children; and the parents' satisfaction with care, burden of patient care (Häusliche Pflegeskala, home care scale, HPS), anxiety and depression (Hospital Anxiety and Depression Scale, HADS), and QoL (Quality of Life in Life-Threatening Illness-Family Carer Version, QOLLTI-F).

RESULTS

Of 43 families newly admitted to PPHC between April 2011 and June 2012, 40 were included in the study. The median interval between the first and second interview was 8.0 weeks. The involvement of the PPHC team led to a significant improvement of children's symptoms and QoL (P<0.001) as perceived by the parents; and the parents' own QoL and burden relief significantly increased (QOLLTI-F, P<0.001; 7-point change on a 10-point scale), while their psychological distress and burden significantly decreased (HADS, P<0.001; HPS, P<0.001).

CONCLUSIONS

The involvement of specialized PPHC appears to lead to a substantial improvement in QoL of children and their parents, as experienced by the parents, and to lower the burden of home care for the parents of severely ill children.

Pediatric advance care planning: a systematic review

BACKGROUND AND OBJECTIVES

Advance care planning (ACP) is increasingly regarded as the gold standard in the care of patients with life-limiting illnesses. Research has focused on adults, but ACP is also being practiced in pediatrics. We conducted a systematic review on empirical literature on pediatric ACP (pACP) to assess current practices, effects, and perspectives of pACP.

METHODS

We searched PubMed, BELIT, and PSYCinfo for empirical literature on pACP, published January 1991 through January 2012. Titles, abstracts, and full texts were screened by 3 independent reviewers for studies that met the predefined criteria. The evidence level of the studies was assessed. Relevant study outcomes were retrieved according to predefined questions.

RESULTS

We included 5 qualitative and 8 quantitative studies. Only 3 pACP programs were identified, all from the United States. Two of them were informed by adult programs. Major pACP features are discussions between families and care providers, as well as advance directives. A chaplain and other providers may be involved if required. Programs vary in how well they are evaluated; only 1 was studied by using a randomized controlled trial. Preliminary data suggest that pACP can successfully be implemented and is perceived as helpful. It may be emotionally relieving and facilitate communication and decision-making. Major challenges are negative reactions from emergency services, schools, and the community.

CONCLUSIONS

There are few systematic pACP programs worldwide and none in Europe. Future research should investigate the needs of all stakeholders. In particular, the perspective of professionals has so far been neglected.

Psychosocial care for the caregivers of primary malignant brain tumor patients

Despite clinical experience that suggests a high burden of care among relatives of individuals with a primary malignant brain tumor (PMBT), little is known about their actual needs. In this study, the caregivers' personal experiences, quality of life, burden of care, and psychological well-being were examined. Fifty-nine percent did not receive any financial aid for home care, 33% had increased risk for psychosomatic problems, 45% had anxiety, and 33% increased depression levels. The caregiver's quality of life was most strongly affected by the burden of care (p < .001) and the patient's mental state (p < .03). To improve the situation, empathetic professionals and an early implementation of palliative care and social work are required.

Recombinant human insulin-like growth factor I (rhIGF-I) for the treatment of amyotrophic lateral sclerosis/motor neuron disease

BACKGROUND

Recombinant human insulin-like growth factor I (rhIGF-I) is a possible disease modifying therapy for amyotrophic lateral sclerosis (ALS, which is also known as motor neuron disease (MND)).

OBJECTIVES

To examine the efficacy of rhIGF-I in affecting disease progression, impact on measures of functional health status, prolonging survival and delaying the use of surrogates (tracheostomy and mechanical ventilation) to sustain survival in ALS. Occurrence of adverse events was also reviewed.

SEARCH METHODS

We searched the Cochrane Neuromuscular Disease Group Specialized Register (21 November 2011), CENTRAL (2011, Issue 4), MEDLINE (January 1966 to November 2011) and EMBASE (January 1980 to November 2011) and sought information from the authors of randomised clinical trials and manufacturers of rhIGF-I.

SELECTION CRITERIA

We considered all randomised controlled clinical trials involving rhIGF-I treatment of adults with definite or probable ALS according to the El Escorial Criteria. The primary outcome measure was change in Appel Amyotrophic Lateral Sclerosis Rating Scale (AALSRS) total score after nine months of treatment and secondary outcome measures were change in AALSRS at 1, 2, 3, 4, 5, 6, 7, 8, 9 months, change in quality of life (Sickness Impact Profile scale), survival and adverse events.

DATA COLLECTION AND ANALYSIS

Each author independently graded the risk of bias in the included studies. The lead author extracted data and the other authors checked them. We generated some missing data by making ruler measurements of data in published graphs. We collected data about adverse events from the included trials.

MAIN RESULTS

We identified three randomised controlled trials (RCTs) of rhIGF-I, involving 779 participants, for inclusion in the analysis. In a European trial (183 participants) the mean difference (MD) in change in AALSRS total score after nine months was -3.30 (95% confidence interval (CI) -8.68 to 2.08). In a North American trial (266 participants), the MD after nine months was -6.00 (95% CI -10.99 to -1.01). The combined analysis from both RCTs showed a MD after nine months of -4.75 (95% CI -8.41 to -1.09), a significant difference in favour of the treated group. The secondary outcome measures showed non-significant trends favouring rhIGF-I. There was an increased risk of injection site reactions with rhIGF-I (risk ratio 1.26, 95% CI 1.04 to 1.54). . A second North American trial (330 participants) used a novel primary end point involving manual muscle strength testing. No differences were demonstrated between the treated and placebo groups in this study. All three trials were at high risk of bias.

AUTHORS' CONCLUSIONS

Meta-analysis revealed a significant difference in favour of rhIGF-I treatment; however, the quality of the evidence from the two included trials was low. A third study showed no difference between treatment and placebo. There is no evidence for increase in survival with IGF1. All three included trials were at high risk of bias.

Errors in palliative care: kinds, causes, and consequences: a pilot survey of experiences and attitudes of palliative care professionals

BACKGROUND

Medical errors have recently been recognized as a relevant concern in public health, and increasing research efforts have been made to find ways of improving patient safety. In palliative care, however, studies on errors are scant.

OBJECTIVE

Our aim was to gather pilot data concerning experiences and attitudes of palliative care professionals on this topic.

METHODS

We developed a questionnaire, which consists of questions on relevance, estimated frequency, kinds and severity of errors, their causes and consequences, and the way palliative care professionals handle them. The questionnaire was sent to all specialist palliative care institutions in the region of Bavaria, Germany (n=168; inhabitants 12.5 million) reaching a response rate of 42% (n=70).

RESULTS

Errors in palliative care were regarded as a highly relevant problem (median 8 on a 10-point numeric rating scale). Most respondents experienced a moderate frequency of errors (1-10 per 100 patients). Errors in communication were estimated to be more common than those in symptom control. The causes most often mentioned were deficits in communication or organization. Moral and psychological problems for the person committing the error were seen as more frequent than consequences for the patient. Ninety percent of respondents declared that they disclose errors to the harmed patient. For 78% of the professionals, the issue was not a part of their professional training.

CONCLUSION

Professionals acknowledge errors-in particular errors in communication-to be a common and relevant problem in palliative care, one that has, however, been neglected in training and research.

Surrogate decision making for patients with end-stage dementia

OBJECTIVE

We aim to explore how health surrogates of patients with dementia proceed in decision making, which considerations are decisive, and whether family surrogates and professional guardians decide differently.

METHODS

We conducted an experimental vignette study using think aloud protocol analysis. Thirty-two family surrogates and professional guardians were asked to decide on two hypothetical case vignettes, concerning a feeding tube placement and a cardiac pacemaker implantation in patients with end-stage dementia. They had to verbalize their thoughts while deciding. Verbalizations were audio-recorded, transcribed, and analyzed according to content analysis. By experimentally changing variables in the vignettes, the impact of these variables on the outcome of decision making was calculated.

RESULTS

Although only 25% and 31% of the relatives gave their consent to the feeding tube and pacemaker placement, respectively, 56% and 81% of the professional guardians consented to these life-sustaining measures. Relatives decided intuitively, referred to their own preferences, and focused on the patient's age, state of wellbeing, and suffering. Professional guardians showed a deliberative approach, relied on medical and legal authorities, and emphasized patient autonomy. Situational variables such as the patient's current behavior and the views of health care professionals and family members had higher impacts on decisions than the patient's prior statements or life attitudes.

CONCLUSIONS

Both the process and outcome of surrogate decision making depend heavily on whether the surrogate is a relative or not. These findings have implications for the physician-surrogate relationship and legal frameworks regarding surrogacy.

Medical futility at the end of life: the perspectives of intensive care and palliative care clinicians

OBJECTIVES

Medical futility at the end of life is a growing challenge to medicine. The goals of the authors were to elucidate how clinicians define futility, when they perceive life-sustaining treatment (LST) to be futile, how they communicate this situation and why LST is sometimes continued despite being recognised as futile.

METHODS

The authors reviewed ethics case consultation protocols and conducted semi-structured interviews with 18 physicians and 11 nurses from adult intensive and palliative care units at a tertiary hospital in Germany. The transcripts were subjected to qualitative content analysis.

RESULTS

Futility was identified in the majority of case consultations. Interviewees associated futility with the failure to achieve goals of care that offer a benefit to the patient's quality of life and are proportionate to the risks, harms and costs. Prototypic examples mentioned are situations of irreversible dependence on LST, advanced metastatic malignancies and extensive brain injury. Participants agreed that futility should be assessed by physicians after consultation with the care team. Intensivists favoured an indirect and stepwise disclosure of the prognosis. Palliative care clinicians focused on a candid and empathetic information strategy. The reasons for continuing futile LST are primarily emotional, such as guilt, grief, fear of legal consequences and concerns about the family's reaction. Other obstacles are organisational routines, insufficient legal and palliative knowledge and treatment requests by patients or families.

CONCLUSION

Managing futility could be improved by communication training, knowledge transfer, organisational improvements and emotional and ethical support systems. The authors propose an algorithm for end-of-life decision making focusing on goals of treatment.

How family caregivers' medical and moral assumptions influence decision making for patients in the vegetative state: a qualitative interview study

BACKGROUND

Decisions on limiting life-sustaining treatment for patients in the vegetative state (VS) are emotionally and morally challenging. In Germany, doctors have to discuss, together with the legal surrogate (often a family member), whether the proposed treatment is in accordance with the patient's will. However, it is unknown whether family members of the patient in the VS actually base their decisions on the patient's wishes.

OBJECTIVE

To examine the role of advance directives, orally expressed wishes, or the presumed will of patients in a VS for family caregivers' decisions on life-sustaining treatment.

METHODS AND SAMPLE

A qualitative interview study with 14 next of kin of patients in a VS in a long-term care setting was conducted; 13 participants were the patient's legal surrogates. Interviews were analysed according to qualitative content analysis.

RESULTS

The majority of family caregivers said that they were aware of aforementioned wishes of the patient that could be applied to the VS condition, but did not base their decisions primarily on these wishes. They gave three reasons for this: (a) the expectation of clinical improvement, (b) the caregivers' definition of life-sustaining treatments and (c) the moral obligation not to harm the patient. If the patient's wishes were not known or not revealed, the caregivers interpreted a will to live into the patient's survival and non-verbal behaviour.

CONCLUSIONS

Whether or not prior treatment wishes of patients in a VS are respected depends on their applicability, and also on the medical assumptions and moral attitudes of the surrogates. We recommend repeated communication, support for the caregivers and advance care planning.

Palliative Care teaching in Germany - concepts and future developments

BACKGROUND

Following recent modifications of the Medical Licensure Act (ÄApprO) in the year 2009, palliative care was introduced as a compulsory 13(th) cross-disciplinary subject (Q13) in the undergraduate curriculum. Its implementation must have taken place before the beginning of the final year ('practical year') in August 2013 and has to be substantiated for the medical exams taking place in October 2014. Very diverse structures pertaining to palliative care teaching were described in previous surveys at various medical faculties in Germany. As a result, the current and future plans and concepts related to content and exams of a mandatory Q13 course at the respective faculty sites should be ascertained.

METHODS

Since 2006, the German Medical Students' Association (bvmd) has been carrying out a bi-annual survey at all medical faculties in Germany regarding the current situation of teaching in the field of palliative care. After designing and piloting an online survey in May 2010, a one-month online survey took place. The data was assessed using a descriptive approach.

RESULTS

31 of 36 medical faculties took part in the survey. At the time of questioning, 15 faculties already taught courses according to the requirements of the new ÄApprO; at three sites the Q13 is yet to be introduced commencing in 2012. A teaching curriculum for Q13 already existed at 15 faculty sites, partly based on the curricular requirements of the German Association for Palliative Medicine (DGP). Six sites described an implementation process as yet without an independent curriculum. Most of the faculties aim for 21-40 course hours, which will for the most part be provided as lectures, seminars or less often in more assisted and intense formats. The majority of the participating faculties intend an examination containing multiple choice questions. At 8 universities there is an independent Chair for palliative medicine (5 more are planned); this was linked with a higher degree of mandatory teaching in alignment with the requirements of the ÄApprO. A broad spectrum of educationally-involved occupational groups, specialist disciplines and external co-operating partners, were mentioned.

CONCLUSION

The infrastructural prerequisites of the present curricular concepts and the degree of implementation of the Q13 according to the requirements of the new ÄApprO diverge significantly among the various medical faculties. The efforts made to produce a qualitatively high standard of teaching with regard to the multifaceted questions concerning the support for severely and terminally ill patients is as much reflected in the survey, as the special implications of an independent Chair for palliative medicine for the implementation of the requirements by law. The participation of various occupational groups in this survey as well as the broad spectrum of those involved highlights the interdisciplinary and multi-professional dimension of teaching in palliative care.

Diagnostic and ethical challenges in disorders of consciousness and locked-in syndrome: a survey of German neurologists

Diagnosis and decisions on life-sustaining treatment (LST) in disorders of consciousness, such as the vegetative state (VS) and the minimally conscious state (MCS), are challenging for neurologists. The locked-in syndrome (LiS) is sometimes confounded with these disorders by less experienced physicians. We aimed to investigate (1) the application of diagnostic knowledge, (2) attitudes concerning limitations of LST, and (3) further challenging aspects in the care of patients. A vignette-based online survey with a randomized presentation of a VS, MCS, or LiS case scenario was conducted among members of the German Society for Neurology. A sample of 503 neurologists participated (response rate 16.4%). An accurate diagnosis was given by 86% of the participants. The LiS case was diagnosed more accurately (94%) than the VS case (79%) and the MCS case (87%, p < 0.001). Limiting LST for the patient was considered by 92, 91, and 84% of the participants who accurately diagnosed the VS, LiS, and MCS case (p = 0.09). Overall, most participants agreed with limiting cardiopulmonary resuscitation; a minority considered limiting artificial nutrition and hydration. Neurologists regarded the estimation of the prognosis and determination of the patients’ wishes as most challenging. The majority of German neurologists accurately applied the diagnostic categories VS, MCS, and LiS to case vignettes. Their attitudes were mostly in favor of limiting life-sustaining treatment and slightly differed for MCS as compared to VS and LiS. Attitudes toward LST strongly differed according to circumstances (e.g., patient’s will opposed treatment) and treatment measures.

[Changing the treatment goal at the end of life: effects of a guideline at a hospital]

BACKGROUND AND OBJECTIVE

Deciding about treatment goals at the end of life is a frequent and difficult challenge to medical staff. As more health care institutions issue ethico-legal guidelines to their staff the effects of such a guideline should be investigated in a pilot project.

PARTICIPANTS AND METHODS

Prospective evaluation study using the pre-post method. Physicians and nurses working in ten intensive care units of a university medical center in Germany answered a specially designed questionnaire before and one year after issuance of the guideline.

RESULTS

197 analyzable answers were obtained from the first (pre-guideline) and 251 from the second (post-guideline) survey (54 % and 58 % response rate, respectively). Initially the clinicians expressed their need for guidelines, advice on ethical problems, and continuing education. One year after introduction of the guideline one third of the clinicians was familiar with the guideline's content and another third was aware of its existence. 90% of those who knew the document welcomed it. Explanation of the legal aspects was seen as its most useful element. The pre- and post-guideline comparison demonstrated that uncertainty in decision making and fear of legal consequences were reduced, while knowledge of legal aspects and the value given to advance directives increased. The residents had derived the greatest benefit.

CONCLUSION

By promoting the knowledge of legal aspects and ethical considerations, guidelines given to medical staff can lead to more certainty when making in end of life decision.
