Transcript

  • 1. Medicine Management in Patients Awaiting Elective Surgery Presented by Joyce McSwan (Managing Director) MedRN BPharm.MAACPA.MAPMA.MPSA.MAPSOC Accredited Consultant Pharmacist
  • 2. Learning Objectives • Understand the principles of medicine management pre and post elective surgery • Discuss the challenges of ‘accidental addicts’ • Discuss the whole person approach in medicine management © Copyright MedRN – www.medrn.com.au - 2012
  • 3. The importance of medication management in pre and post elective surgery • Surgical patients – many are elderly • Polypharmacy • Compromised renal or hepatic function and disease • Not adequately educated about their medication regimens
  • 4. Key Focus of medication management • Patient Safety • Functional recovery • Long term outcomes
  • 5. Limited evidence for guidance • Scant RCT to guide • Recommendations from: – Expert consensus – Case reports – In vitro studies – Pharmaceutical companies – Other known data
  • 6. General considerations in perioperative medication management 1. A comprehensive medication history is fundamental • Understand a patient’s comorbidities • Assess the risk of perioperative decompensation • Look at the complete inventory: – All prescription medications – All over-the-counter (OTC) agents (including – Non- Steroidal anti-inflammatory drugs [NSAIDs] – All vitamins – All herbal medications
  • 7. General considerations in perioperative medication management 2. When to stop and when to resume? • Limited guidance from literature – Withdrawal effects – Disease progression – Drug interactions with anaesthetic and post operative medicines.
  • 8. General considerations in perioperative medication management 3. Withdrawal Potential • Abrupt withdrawal • Unnecessary complications • Understanding pharmacokinetics • Comprehensive list as part of protocol • Risk vs. benefit of cessation • Legal issues with inappropriate cessation • Medicines to consider: – SSRIs – Beta-blockers – Clonidine – Statins – Corticosteroids – Opioids
  • 9. General considerations in perioperative medication management 4. Patients on chronic drugs are more likely to have complications: 1025 surgical patients 49% - taking medicines (other than vitamins) unrelated to the procedure 1 1. Kennedy JM, van Rij AM, Spears GF, Pettigrew RA, Tucker IG. Polypharmacy in a general surgical unit and consequences of drug withdrawal. Br J Clin Pharmacol 2000; 49:353–362.
  • 10. Study shows …… • Medication use has important perioperative consequences • Odds ratio for postop complication = 2.7 if patients were taking a drug unrelated to surgery.
  • 11. General considerations in perioperative medication management • Complication risk elevated for: – CV drugs or CNS agents – Nil by mouth order for more than 24 hours before or after surgery - alternative route considered – > 1 hour operation duration. • This study reflects destabilization of the disease processes for patients taking chronic medications that require interruption.
  • 12. General considerations in perioperative medication management 5. Unintended discontinuation of chronic drugs • Resumption overlooked • Increase risk of medical errors in transition between hospital discharge to primary care. • Study found 11.4% patients who had elective surgery did not resume their indicated chronic warfarin therapy within 6 months after pre- surgical discontinuation. 2 2. Bell CM, Bajcar J, Bierman AS, Li P, Mamdani MM, Urbach DR. Potentially unintended discontinuation of long-term medication use after elective surgical procedures. Arch Intern Med 2006; 166:2525–2531.
  • 13. General considerations in perioperative medication management 6. Additional Considerations A) Stress response to surgery – A challenge for homeostasis – Increased sympathetic tone – Release of pituitary hormones
  • 14. General considerations in perioperative medication management 6. Additional Considerations B) Unreliable absorption of oral medications post operatively – Villous atrophy – Diminished blood flow to GIT – Oedema – Mucosal ischaemia – Diminished motility from postoperative ileus – Use of narcotics
  • 15. Key Points in perioperative medication management • Continue medications with withdrawal potential • Discontinue medications that increase surgical risk and are not essential for short-term quality of life • Use clinical judgment when neither of the above two principles applies – Other medications are given in the narrow perioperative time – Alteration in the metabolism and elimination of chronic drugs may be altered.
  • 16. Elective surgery waiting times • Reduction in waiting times – 2007-2008 : 3% – 2011-2012 : 2.7% • 11.9% > 1 year: Total Knee replacement • 5.4% > 1 year: Orthopaedic surgery • 5.6% > 1 year: Ear, nose and throat surgery • 0.1% > 1 year: Cardiothoracic surgery Australian Institute of Health and Welfare: Australian Hospital Statistics 2011-2012
  • 17. Challenges of medication management in the waiting period • 11.9% > 1 year: Total Knee replacement • 5.4% > 1 year: Orthopaedic surgery • Definition of Chronic Pain: IASP - An unpleasant sensory and emotional experience caused by actual or potential tissue damage or described in terms of such damage Chronicity - > 3-6 months
  • 18. Neuropathic Progression • Pain connections change • Sensitivity of cells change • Permanent change • Pain continues in the absence of any other • Changes long after the initial injury has healed NEUROPLASTICITY
  • 19. Potential risk for opioid addiction while waiting….. • “Accidental Addicts” - true addiction or pseudoaddiction • Risk of addiction worsened by elective surgery waiting lists. – Little self management options – Taking more analgesics – Accessibility of OTC analgesics • In trials, database program that records opioid prescription history of patients (PSA, Tasmania)
  • 20. Opioid Dependency Risk Falls risk Memory impairment Worsened pain / CNS changes Mental health decline Deconditioning Long term Pain, awaiting surgery Elective Surgery Wait List
  • 21. Whole Person Approach to Medicine Management • Generalist approach – Seeing the person as a whole and in the context of their family and wider social environment – Demonstrating concern not only for the needs of the presenting patient, but also for the wider group of patients or population – Engaging in effective multi-professional working and co-learning
  • 22. Whole Person Approach to Medicine Management • Biographical perspective • Developing therapeutic rapport • An enabling process for the patient: • Move individual from where they are • Increasing understanding and knowledge • Supporting emotional capabilities • Empowerment making decisions about undergoing investigations and treatment options.
  • 23. Applying it to the landscape of elective surgery • Medicine Management = National Medicines Policy • Quality Use of Medicines • Quality-Safety-Efficacy • Applies to pre and post operative settings
  • 24. Quality Use of Medicines • Choosing suitable medicines if a medicine is considered necessary so that the best available option is selected taking into account: o The individual o The clinical condition o Risks and benefits o Dosage and length of treatment o Any co-existing conditions o Other therapies o Monitoring considerations o Costs for the individual, the community, and the health system as a whole
  • 25. Waiting positively • Pre-operative focus : – “Pre-hab” programs – Increase education on realistic expectations, goal setting, pacing  SELF MANAGEMENT – Present other options for consumers through greater health networks = A proactive approach
  • 26. Waiting positively • Pre-operative focus : – Optimise medicine therapy but minimise dependence on medicines through education and utilisation of programs currently available: • Home Medicines Review • Credible resource - Australian Pain Management Association’s pain support groups • Alcohol and drug use • Analgesic intolerance • Holistic evaluation of lifestyle, injury prevention, gaining information about the operation
  • 27. Advertising slogans:
  • 28. Healing patiently • Resumption of medication unrelated to surgery • Patient’s expectations of chronic pain in acute pain setting • Multi-modal drug approach = minimise side effects • Being honest with the pain  restoration of functionality • Biographics – support network in place
