Insights

The national palliative care (PC) coding standard improved patient identification and services. While PC coding influences the hospital standardised mortality ratio (HSMR), its impact is modest, with other factors driving HSMR improvements.

Area of Science:

  • Health Services Research
  • Palliative Care
  • Health Informatics

Background:

  • The implementation of a national palliative care (PC) coding standard aimed to improve the identification of patients receiving PC services.
  • Understanding the impact of this standard on coding practices and its relationship with hospital performance indicators like the hospital standardised mortality ratio (HSMR) is crucial.

Purpose of the Study:

  • To examine palliative care (PC) coding practices following the introduction of a national coding standard.
  • To assess the association between PC coding practices and hospital standardised mortality ratio (HSMR) results.

Main Methods:

  • Analysis of approximately 16 million hospital discharges from the Canadian Institute for Health Information (CIHI) Discharge Abstract Database (2006-2013).
  • Assessment of PC coding frequency, adherence to guidelines, and in-hospital mortality rates.
  • Calculation of a variant HSMR-PC including PC cases to compare with the standard HSMR.

Main Results:

  • Palliative care (PC) coding frequency increased from 0.78% to 1.12% of separations, with improved adherence to guidelines.
  • National HSMR declined by 22% and HSMR-PC by 17%, with modest differences between the two measures.
  • Crude mortality among HSMR cases decreased, and overall in-hospital mortality saw significant reductions.

Conclusions:

  • The national coding standard successfully increased the identification of palliative care patients and services.
  • Improvements in HSMR are driven by multiple factors including reduced in-hospital mortality and increased coded comorbidities.
  • Palliative care coding has a modest influence on the HSMR indicator, with other drivers playing a more significant role.

Documentation in Long-Term and Home Healthcare Setting

Documentation in long-term care facilities and home healthcare settings is crucial for ensuring continuous, coordinated, and comprehensive care for patients. Each setting has its specific documentation processes and tools:

Continuing Care

Continuing care describes the variety of health, personal, and social services provided over a prolonged period. The need for continuing care is increasing because people are living longer. Many people do not have families or others to care for them. Continuing care is mainly for patients who are disabled, functionally dependent, or suffering from a terminal disease. It is available within institutional settings or in homes. Examples include nursing centers or facilities, assisted living,...

Standards of Care I

Federal statutes profoundly impact nursing practice, providing critical guidelines to ensure patient care is equitable, accessible, and of the highest quality. The following laws address distinct aspects of healthcare provision and patient rights:

Methods of Documentation VI: Case Management Model

The case management model is a multidisciplinary approach that involves healthcare professionals from diverse disciplines, such as physicians, nurses, therapists, social workers, and pharmacists, working collaboratively to address the various needs of patients. Each healthcare professional brings unique expertise and perspectives, contributing to a more comprehensive understanding of the patient's condition and tailoring treatment plans accordingly.
For example, a patient with a chronic...
