Cancer Survival Analysis

Cancer Survival Analysis

Cancer survival analysis focuses on quantifying and interpreting the time from a key starting point, such as diagnosis or the initiation of treatment, to a specific endpoint, such as remission or death. This analysis provides critical insights into treatment effectiveness and factors that influence patient outcomes, helping to shape clinical decisions and guide prognostic evaluations. A cornerstone of oncology research, survival analysis tackles the challenges of skewed, non-normally...

Methods of Documentation II: POMR

Methods of Documentation II: POMR

The Problem-Oriented Medical Record (POMR) revolutionized medical record-keeping by introducing a systematic approach focusing on the patient's problems rather than merely listing symptoms. Dr. Lawrence Weed's introduction of this method in the 1960s marked a significant advancement in medical documentation. The POMR framework consists of four key components: the database, problem list, plan of care, and progress notes.

Methods of Documentation VI: Case Management Model

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...

Area of Science:

Health Services Research
Quality Improvement Science
Oncology Practice Management

Background:

Clinical efficiency is crucial for value-based healthcare.
Outpatient radiation oncology clinics face workflow challenges impacting patient care and costs.
Optimizing patient flow is essential for improving healthcare delivery.

Purpose of the Study:

To identify workflow inefficiencies in high-volume outpatient radiation oncology clinics using time-driven activity-based costing (TDABC).
To evaluate the impact of implementing a new clinical workflow on efficiency and patient satisfaction.
To quantify financial savings associated with workflow improvements.

Main Methods:

A quality improvement study was conducted across GI, Genitourinary (GU), and Thoracic Radiation Oncology departments, plus community sites.
Time-driven activity-based costing (TDABC) was employed to map and optimize outpatient consult workflows.
Patient encounter metrics were collected using electronic medical records, with time metrics compared via Mann-Whitney U tests.

Main Results:

Overall patient encounter cycle time was reduced by 21% in GI, 18% in GU, and 12% in community sites.
Median financial savings per consult ranged from $30 to $52 USD across departments.
Patient satisfaction remained high, with 99% reporting adequate provider time and 91% timely care.

Conclusions:

Time-driven activity-based costing (TDABC) effectively identifies opportunities for improving clinical efficiency.
Workflow modifications based on TDABC analysis led to significant reductions in encounter cycle times.
The implemented changes resulted in substantial financial savings and high patient satisfaction.
