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 illness...

Methods Of Healthcare Delivery System

At the different levels of the healthcare system, we see varying methods of healthcare used. These methods include managed care systems, case management, and primary healthcare.
Managed Care System:
The managed care system is designed to control the cost while maintaining the quality of care. The patient's care from admission to discharge is planned by the primary care provider or the case manager, also known as the gatekeeper. In a managed care system, the number of care providers is limited...

Preoperative clinic visits for low-risk surgery vary widely, driven mainly by surgeon preferences rather than patient risk. Standardizing these evaluations could improve healthcare value by reducing unnecessary visits.

Area of Science:

  • Healthcare Management
  • Surgical Optimization
  • Ambulatory Surgery

Background:

  • Preoperative evaluation is crucial for surgical optimization but lacks standardized protocols based on patient risk.
  • Current practices for preoperative clinic utilization show significant variation, particularly for low-risk ambulatory surgery.

Purpose of the Study:

  • To characterize preoperative clinic use in healthy, low-risk ambulatory surgery patients.
  • To identify practice- and surgeon-level factors contributing to variation in preoperative clinic utilization.
  • To find opportunities for improving quality and value in preoperative care.

Main Methods:

  • Retrospective cohort study of low-risk adult patients (ASA classes I-II) undergoing low-risk ambulatory surgery (OSS 1-2).
  • Analysis of preoperative clinic visits within 30 days of surgery.

  • Mixed-effects logistic regression to assess surgeon and procedure variance.
  • Surveys and semistructured interviews with surgeons and advanced practice providers.

    • Main Results:

    • 52% of 3469 eligible cases had a preoperative clinic visit, with utilization varying from 22% to 88% across services.
    • Surgeon (45%) and procedure type (11%) explained significant variance in clinic use.
    • Clinician surveys and interviews revealed heterogeneity in perceived clinic purpose and referral criteria.

    Conclusions:

    • Preoperative clinic utilization for low-risk ambulatory surgery is highly variable and surgeon-dependent.
    • Heterogeneity in referral practices indicates a need to align evaluations with patient risk.
    • Standardizing preoperative care pathways can enhance value and potentially reduce unnecessary clinic visits.
