Can palliative care be provided to a patient with adenocarcinoma of the lungs, uncontrolled diabetes mellitus (DM) on insulin, requiring High Flow Nasal Cannula (HFNC) with high Fraction of Inspired Oxygen (FIO2), and taking antipsychotic medications, who is too weak for chemotherapy?

Palliative Care Management for Advanced Lung Cancer Patient with Multiple Comorbidities

Palliative care should absolutely be provided to this 75-year-old patient with adenocarcinoma of the lungs, as it is recommended to be introduced early in the treatment course for all patients with advanced lung cancer, regardless of their comorbidities or treatment status. 1

Initial Assessment and Care Planning

• Begin with a comprehensive discussion about the patient's prognosis and goals of care, as this is essential for all patients with advanced lung cancer 1
• Establish realistic treatment expectations, focusing on quality of life rather than curative intent, given the patient's advanced cancer, multiple comorbidities, and inability to undergo chemotherapy 1
• Introduce palliative care as a holistic approach that addresses both medical and non-medical aspects of illness, not just as end-of-life care 1
• Conduct an advance care planning discussion, including preferences for life-sustaining treatments and end-of-life care options 1

Symptom Management at Home

Respiratory Symptom Management

• Optimize HFNC settings at home with target oxygen saturation of 88-92% 2
• Consider reducing FiO2 from current 60% if possible while maintaining adequate oxygenation 1
• Implement opioids (such as morphine) for dyspnea relief, which becomes increasingly important as disease progresses 1
• Add benzodiazepines if anxiety accompanies breathlessness 1
• Position the patient upright or in a comfortable position to ease breathing 1

Diabetes Management

• Simplify diabetes regimen by reducing insulin monitoring frequency and adjusting insulin doses to prevent hypoglycemia rather than achieve tight control 3
• Focus on preventing symptomatic hyperglycemia rather than maintaining normal blood glucose levels 3
• Consider transitioning to once-daily long-acting insulin if the patient is eating poorly 3

Antipsychotic Medication Management

• Continue antipsychotic medications to prevent decompensation of mental status 1
• Monitor for and manage any side effects that may affect quality of life 1
• Consider dose adjustments if sedation is excessive or if the medication is contributing to weakness 1

Pain and Comfort

• Implement regular pain assessment using appropriate scales 1
• Provide around-the-clock pain medication with breakthrough doses as needed 1
• Consider non-pharmacological approaches such as positioning, massage, and relaxation techniques 1

Psychosocial and Spiritual Support

• Provide emotional support to help the patient reshape goals and hopes based on changing reality 1
• Include family members in care planning and education about the disease trajectory 4
• Address spiritual concerns and existential distress that may arise 1
• Facilitate completion of important personal matters and relationship closure 1

Coordination of Care

• Establish a multidisciplinary team including palliative care specialists, primary care physician, pulmonologist, endocrinologist, and social worker 4, 5
• Arrange for home health services to assist with medical equipment, medication management, and personal care 5
• Provide caregiver education and support regarding medication administration, oxygen therapy, and recognition of emergency situations 5
• Consider hospice referral when appropriate, based on disease progression and patient/family preferences 1

Monitoring and Follow-up

• Schedule regular home visits by palliative care team members to assess symptom control and adjust management plan 6
• Implement telehealth consultations when in-person visits are challenging 7
• Develop clear criteria for when emergency department visits or hospitalization may be necessary 7
• Create a communication plan between the patient, family, and healthcare team 1

Special Considerations

• Avoid overly aggressive nutritional support that may increase suffering in advanced disease 1
• Focus on comfort measures rather than aggressive medical interventions as the disease progresses 1
• Be aware that early palliative care has been shown to improve both quality of life and survival in patients with metastatic non-small cell lung cancer 6
• Recognize that the goals of care will shift over time from disease management to comfort as the illness progresses 1

By implementing this comprehensive palliative care approach, the patient can receive appropriate symptom management and support at home, enhancing quality of life while respecting the limitations imposed by their advanced disease and multiple comorbidities.
