Operating compass managers typically use financial management information theorys to account for revenues and costs(1) With micro-costing (ie, "bottom-up") accounting orders the labor and materials required to provide patient care can be tracked as care be founds Managers then can determine whether a resource is a fixed or a variable cost

DETERMINING FIXED AND VARIABLE COSTS

Fixed costlinesss remain constant over a predefined whirl of activity and length of time. For example, fixed charges may be defined as expenditures that do not vary as the compass of activity (ie, number of cases) increases 20% through the whole extent of a one-year period. Fixed richnesss such as capital equipment or rupture paid for the surgical facility, do not change in direct proportion to the number of patients.

In contrast to fixed charges variable costs change in direct proportion to the number of patients. For example, the splendor of knee implants is a variable expense because each patient undergoing total knee replacement surgery necessitys a knee implant (ie, variable charges = number of patients x require to be paid [i]or[/i] undergone of each knee implant).(2) The incremental costliness (ie, the increase in outlays resulting from caring for the same additional patient) includes the take away from of the knee implant. line of junctions drapes, and medications are other examples of variable costlinesss Changes in how physicians practice medicine as a accrue of implementation of clinical pathways predominantly affect variable costs(3)

Resources related to surgical patient care are a variable richness if an increase in the number of cases increases the outlays associated with surgery. Operating apartment labor costs (eg, wages for nourishs anesthesia care providers, surgical technologists, and perfusionists) can be fixed or variable. Operating field labor costs for full-time employee are fixed through the whole extent of modest changes in surgical body but become variable when an increase in the number of cases requires hiring additional employees

To illustrate the importance of fixed and variable staffing preciousnesss the effect on OR charges of canceling a knee replacement case forward the scheduled day of surgery can be considered. In this example, an OR that busys full-time staff members does not eliminate its fixed labor splendors by not performing the case. As another example, the incremental labor take away froms associated with staffing ORs for an additional 40 coronary artery bypass graft (CABG) cases through year is zero, if the number of existing full-time employee is sufficient to staff the recently made known cases.(4)

WILL THE CONTRACT BE PROFITABLE?

Payers can contract with a hospital to provide a particular surgical practice For example, a hospital might be paid $20000 for each patient who undergoes a CABG case, regardless of by what mode much it actually costs the hospital to care for the patient. In negotiating the contract, OR managers ne to render certain the variable costs of performing the additional cases are not higher than the incomes If a contract's contribution margin (ie, return minus variable costs) is positive, performing the recent cases contributes to overall hospital profit.(5)

To estimate the variable charges of caring for new patients subject to a contract, OR managers must identify the awaited number of patients to be added to the hospital's practice. This helps determine if there is enough capacity in the hospital to absorb the recently made known cases. Operating room labor require to be paid [i]or[/i] undergones must be estimated accurately because OR staff member wages are the single greatest require to be paid [i]or[/i] undergone of delivering surgical care.(6)

This investigation applies previously published computer simulation research about OR scheduling to analyze to what extent to estimate the cost of OR staffing.(7) In this reflection OR staff members include several health care professionals, like as nurses and anesthesia care providers. If each OR staff member is compensated differently (eg individual may be part-time hourly, and common may be salaried), a separate analysis is performed for each.

EXAMPLE USED FOR ANALYSIS

The following example, in which a cluster of three cardiac surgeons works exclusively at common hospital, illustrates the analysis. The couple senior cardiac surgeons have established referral patterns and have busy workloads. The junior cardiac surgeon Dr Jone has joined the practice and wants to increase the number of conducts he performs. The hospital has additional OR time and space available for the procedures

A health care insurer suits a reduced package price for CABG cases to be performed at the hospital. If the hospital accepts the contract, approximately 40 additional elective CABG cases would be performed in the surgical suite by year. As Dr Jones wants to increase his caseload, chiefly of these new cases would be performed by means of him.

To evaluate the calculate uponed profitability of this new contract, the OR manager must determine for what cause much it will cost for an additional patient to be exposed to a CABG case. Specifically, the OR manager must calculate the OR labor costlinesss In this hypothetical, simple example, the incremental OR labor splendor for new cases depends on

* for what cause employees are paid (ie, part-time versus full-time, hourly versus salaried) and
