Parkinson's Disease in Acute Care
Introduction
This guidance highlights the importance of continuing Parkinson's disease (PD) medication and covers the first-line management of PD patients who have:
- Nil by mouth status
- Confusion / hallucination / agitation
- Constipation / delayed gastric emptying
- Dizziness and falls
- Nausea and vomiting
Assessment / monitoring
It is crucial not to stop PD drugs for any significant length of time i.e. >2 hours or to miss any doses as there is a risk of Neuroleptic Malignant-Like Syndrome (Parkinson hyperpyrexia syndrome, PHS) which may be fatal. Symptoms include rigidity, pyrexia, and reduced conscious level. There may be features of autonomic instability, and serum creatine kinase (CK) may be elevated. Complications of PHS include acute renal failure, aspiration pneumonia, deep venous thrombosis / pulmonary embolism and disseminated intravascular coagulation.
General management
Prescribing and administration of PD medicines
It is important for PD medications to be administered at exact times. Annotate dose timings clearly on the prescription chart. It is recommended that levodopa should be taken within 30 minutes of its prescribed administration time (NICE guidance - Parkinson's disease 2018 [QS164]).
Location of PD medicines on acute sites
If the patient does not have an individual supply of their PD medication, access supplies via the pharmacy or the local main holding areas of PD medications across NHSGGC. See 'Parkinson's Disease Medication Stocklist, Acute Hospitals' guideline for details on NHSGGC StaffNet / Clinical Info / Clinical Guideline Directory (link only active if accessing via NHS computer).
If PD medicine is not available as above, contact pharmacy (see Appendix 6 for contact details) during working hours, or the on-call pharmacist outwith working hours, for supply.
Inform PD nurse specialist of all PD patient admissions (see Appendix 6 for contact details).
Drug therapy / treatment options
Nil by mouth patients
Refer to PD specialist (see Appendix 6 for contact details). If PD specialist is not available please refer to the 'Parkinson’s Disease (PD)-Nil by Mouth Guidance, Acute' on NHSGGC StaffNet / Clinical Info / Clinical Guideline Directory (link only active if accessing via NHS computer).
Advice can also be sought from a clinical pharmacist, Medicines Information (see Appendix 6 for contact details) or on-call pharmacist (out of hours) regarding alternative formulations.
Confusion / hallucination / agitation
Constipation / delayed gastric emptying
- PD medicines and PD itself may be associated with constipation / delayed gastric emptying.
- Constipation / delayed gastric emptying may interfere with how well PD medications are absorbed, making them less effective.
- Review need for drugs which can precipitate constipation or alter gastric transit time e.g. antacids, iron and calcium containing preparations.
- Refer to Management of Constipation for therapeutic management.
- Refer to PD specialist as soon as possible if PD symptoms are uncontrolled.
Dizziness and falls
- Review need for drugs which precipitate postural hypotension or affect cardiac function e.g. anti-hypertensives, heart failure drugs, selective serotonin reuptake inhibitors (SSRIs), tricyclic antidepressants, anticholinergics, acetylcholinesterase inhibitors.
- PD medications and PD itself may be associated with orthostatic hypotension (check standing BP).
- Refer to PD specialist for assessment as soon as possible.
Nausea and Vomiting
Subcutaneous Apomorphine (for infusion)
- All patients admitted to hospital on apomorphine should be referred to the PD nurse specialist or movement disorders team for advice as soon as possible (see Appendix 6 for contact details).
- An NHSGGC monograph for maintaining 'Apomorphine Subcutaneous Infusion Treatment in Patients Admitted to Hospital' is available on NHSGGC StaffNet / Clinical Info / Clinical Guideline Directory (link only active if accessing via NHS computer).
- Apomorphine should only be instigated with the guidance of a prescriber experienced in PD (it is not suitable for emergency administration in a drug naive patient). If a patient is already established on this then it must be continued.
Co-careldopa intestinal gel (Duodopa®)
- All patients admitted to hospital on Duodopa® intestinal gel should be referred to the PD nurse specialist or movement disorders team for advice as soon as possible (see Appendix 6 for contact details).
- An NHSGGC monograph - 'Duodopa® Monograph for Maintaining Co-careldopa (Duodopa®) Intestinal Infusion Treatment in Patients Admitted to Hospital' - is available on NHSGGC StaffNet / Clinical Info / Clinical Guideline Directory (link only active if accessing via NHS computer). The Duodopa® support helpline can be contacted (see Appendix 6 for contact details) if further advice is required and a PD specialist is not available.
- Duodopa® intestinal gel should only be instigated under specialist guidance. It is not suitable in an emergency situation as it requires the insertion of a percutaneous endoscopic gastrostomy with jejunal (PEG-J) tube. If a patient is already established on this then it must be continued.
