Levels of Medical Intervention and End-of-Life Practices in Long-Term Care Centres.

Background: Levels of medical intervention (LMI) are legal documents in which physicians record patient preferences, or those of their designated substitute decision-makers, concerning end-of-life care. Studies suggest that, although LMI are intended to orient clinical practice, their function tends to be limited to logistical aspects of care. How LMI shapes or guides patient-centred, end-of-life care remains unclear. The aim of this study was to examine possible associations between LMI and certain aspects of end-of-life care practices in LTCC, such as nurse-documented patient experiences of pain, and prescription and administration of medication. Methods: A retrospective descriptive study of 100 files retrieved from a clinical database of deceased patients in LTCCs located in an urban integrated health and social service organization in Québec, Canada, was conducted. Results: Significant associations between last documented LMI and frequency of narcotic prescription and administration, at either regular intervals or PRN, are highlighted. The time delay between last LMI assessment and patient death was one week or less for 39.4% of cases. Conclusion: These results suggest that LMI assessment practices may not correspond to their intended use. A short time frame between last LMI (L-LMI) assessment and patient death may suggest less-than-optimal patient comfort in end-of-life care.
