This study explores the views of healthcare professionals regarding care and treatment goals in irreversible terminal delirium and their effect on patients and caregivers.

We conducted a qualitative interview study of healthcare professionals (palliative care physician, oncologist, psycho-oncologist, and clinical psychologist) engaged in the treatment of terminally ill cancer patients. We assessed the views of healthcare workers regarding treatment goals in terminal delirium and their effect on patients and their families.

Of the 21 eligible healthcare professionals, 20 agreed to participate in this study. Three of the professionals had experience with treating terminal delirium as family caregivers. We identified five important aspects of treatment goals in terminal delirium based on the views of healthcare professionals: (1) adequate management of symptoms/distress, (2) ability to communicate, (3) continuity of self, (4) provision of care and support to families, and (5) considering a balance (between symptom alleviation and maintaining communication; between symptom alleviation and family preparations for the death of patients; balance between specific treatment goals for delirium and general treatment goals).

According to the views of healthcare workers questioned in this study, goals of care and treatment in terminal delirium are multidimensional and extend beyond simply controlling patient symptoms.

This study investigates the usefulness of the Structured Interview for Competency and Incompetency Assessment Testing and Ranking Inventory (SICIATRI) for cancer patients, which is a structured interview that assesses a patient's competency in clinical practice.

The SICIATRI, originally developed to measure patients' competency to give informed consent, were administered referred cancer patients who needed for assessing medical decision making capacity. The usefulness of the SICIATRI was investigated retrospectively. Recommendation for modification of the SICIATRI for cancer patients if applicable were made by the research team.

Among the 433 cancer patients referred for psychiatric consultation, 12 were administered the SICIATRI and all of the administration were conducted without big problems. All patients were 60 years or older. The most common purpose for competency evaluation was to analyze patients' understanding of the anti-cancer treatment proposed by oncologists, followed by their refusal of the treatment. Half of the patients (n = 6) were diagnosed with delirium and three among them were judged as having the most impaired status of a patient's competency. Two patients (17%) were diagnosed with major depression and another two (17%) were mental retardation and each one patient was diagnosed with dementia and past history of alcohol dependence. Among 6 patients without delirium 5 subjects including a dementia patient were judged as fully competent. Total of 5 small potential modifications of the SICIATRI for its use with Japanese cancer patients were recommended.

Our experience suggests that the SICIATRI is a useful instrument for psycho-oncology clinical practice.

Social anxiety disorder is one of the most popular psychiatric disorders in the general population and is also well known as a very common comorbid psychiatric disorder among patients with major depression. On the other hand, social anxiety disorder has been termed “the neglected anxiety disorder” because its diagnosis is often missed. Furthermore, the potential impact of social anxiety disorder on the psychological distress of cancer patients has not been reported.

We encountered two cancer patients with refractory depression after cancer diagnosis, in whom comorbid social anxiety disorder was unexpectedly detected during a subsequent follow-up.

To the best of our knowledge, this is the first report to discuss the potential impact of social anxiety disorder on cancer patients' distress. These two cases may help to improve our understanding of the complicated mental health problems of cancer patients and the potential influence of social anxiety disorder on patients' follow-up medical treatment.

Comorbid social anxiety disorder should be considered when a cancer patient's depression is resistant to treatment and the existence of communication problems between the patient and the medical staff is suspected.
