Summary
This study introduces a new model for optimizing elective surgery scheduling in private clinics, improving resource use and reducing patient stays. The integrated approach considers patient flow and surgeon availability for efficient healthcare operations.
Area of Science:
- Operations Research
- Healthcare Management
- Applied Mathematics
Background:
- Healthcare facilities face challenges in optimizing surgical scheduling.
- Private clinics have unique constraints, including independent surgeons.
- Efficient resource utilization is crucial for cost-effectiveness and patient care.
Purpose of the Study:
- To develop and evaluate models for an Integrated Elective Surgery-Scheduling Problem (IESSP).
- To optimize resource allocation (beds, operating rooms) and patient sequencing.
- To minimize patient length of stay and overnight stays.
Main Methods:
- Formulation of two Mixed Integer Linear Programs (MILP) for the IESSP.
- Modeling the problem as a hybrid flow-shop with recirculation, synchronization, dedicated machines, and blocking.
- Empirical testing on real-world data from Clinique Ennasr and synthetic instances.
Main Results:
- The proposed MILP models effectively address the complexities of surgery scheduling.
- The models successfully minimized average patient length of stay and overnight stays.
- Instances with up to 44 surgical cases were solved within reasonable CPU time.
Conclusions:
- The developed MILP models provide an efficient solution for integrated elective surgery scheduling.
- The approach is applicable to private healthcare facilities with independent surgeons.
- The findings contribute to improved operational efficiency and patient management in surgical settings.

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.

Secondary healthcare is offered by a specialist, generally in hospitals or clinics for patients referred by primary healthcare providers. It occurs when a person has an illness or injury that requires specific medical care. Secondary care is often referred to as acute care. Secondary care can range from uncomplicated care to repair a minor laceration or treat a strep throat infection to more complicated emergent care, such as treating a head injury sustained in an automobile accident. Whatever...

Hospitals offer medical and surgical care to the sick and injured, along with accommodation while they recover. At the same time, they also provide outpatient, emergency, psychiatric, and rehabilitation services to meet various community needs. In addition to providing medical care, hospitals also act as hubs for medical research and training. Hospitals use clinical procedures and evidence-based practice standards to deliver patient care. To deliver safe and efficient care, a nurse must stay up...

PK–PD modeling has significantly influenced FDA regulatory decisions, particularly drug approval, dosage optimization, and labeling. These models integrate pharmacokinetics (PK) and pharmacodynamics (PD) to predict drug behavior and effects, aiding in optimizing dosing regimens and enhancing the probability of clinical trial success.One notable example is Nesiritide (Natrecor®), a recombinant human brain natriuretic peptide for treating acute decompensated congestive heart failure...

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.
