Continuing Care01:25

Continuing Care

1.6K
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,...

Restorative Care01:19

Restorative Care

2.1K
Restorative care is provided once a patient has been discharged from a healthcare facility and requires additional services. The additional services include home care, rehabilitation programs, and extended care. Restorative care centers help the patient regain their previous level of functioning or acquire a new level of functioning due to the incapacitating effects of a disease or a disability. It aims to assist patients in enhancing their quality of life by encouraging independence,...

Actuarial Approach01:20

Actuarial Approach

155
The actuarial approach, a statistical method originally developed for life insurance risk assessment, is widely used to calculate survival rates in clinical and population studies. This method accounts for participants lost to follow-up or those who die from causes unrelated to the study, ensuring a more accurate representation of survival probabilities.
Consider the example of a high-risk surgical procedure with significant early-stage mortality. A two-year clinical study is conducted,...

Documentation of Nursing Diagnosis

1.4K
The nurse documents nursing diagnoses and enters them into the patient record. The identified patient's nursing diagnosis is either written out with a plan of care or entered into the electronic health record.
In some settings, data-driven computerized decision support systems are in place, allowing for more accurate nursing diagnoses. The database within one of these systems includes diagnostic labels defining characteristics, activities, and indicators for nursing. A nurse enters...

Area of Science:

  • Gerontology and Public Health
  • Health Informatics
  • Epidemiology

Background:

  • Predicting unexpected deaths in long-term care (LTC) facilities is vital for resident safety and quality improvement.
  • Identifying at-risk individuals can inform clinical decisions and policy development.
  • Existing methods require evaluation for accuracy in predicting mortality events.

Purpose of the Study:

  • To compare the predictive performance of logistic regression (LR), mixed-effect LR (mixLR), and XGBoost for unexpected deaths in LTC residents.
  • To identify reliable models for detecting facilities with potentially higher rates of unexpected mortality.
  • To establish a foundation for future comparisons of facility-level mortality differences.

Main Methods:

  • Retrospective cohort study utilizing Resident Assessment Instrument Minimum Data Set (RAI MDS) data from Ontario, Canada (April 2017-March 2018).
  • Application of LR, mixLR, and XGBoost algorithms to predict individual mortality within 5 to 95 days post-assessment.
  • Analysis of a cohort of 106,366 LTC residents, including 22,419 deaths.

Main Results:

  • XGBoost demonstrated superior calibration and discrimination (C-statistic 0.837) compared to mixLR (0.819) and LR (0.813).
  • All models showed high correlation in predicting death (LR-mixLR: 0.979).
  • A combined model approach identified 210 unexpected deaths (0.9% of observed deaths) with low false positives.

Conclusions:

  • XGBoost offers enhanced predictive accuracy for unexpected deaths in long-term care settings.
  • Combining multiple predictive models can improve the detection of facilities with elevated unexpected mortality rates.
  • These models can support ongoing surveillance and quality assurance initiatives at multiple administrative levels.
