Meditech South Africa (Pty) Ltd provides software solutions to meet the information needs of healthcare organizations in Africa and the Middle East. According to their website, the software can encompass all areas of healthcare from doctors’ offices to hospitals. While their software products are generally patient centric, healthcare cost management also features in some of their products. For example, the software designed for hospitals includes some functionality for finance managers on cost accounting. The functions include budgets and standard cost definition. Costs can be defined for labor, materials and overhead and can draw cost information from other Meditech software modules. With standard costs defined, actual costs can be compared to standard/budget. Standard costs can also be used as a basis to reimburse costs from health insurers, or actual costs of providing the services can be compared to reimbursement levels. The software also includes several reports such as variance reports by department, labor cost variances and flexible budget reports, all of which are useful for budgetary control and future budget preparation. Integration with other Meditech software modules and other systems implies cost data can be calculated at a departmental, procedure or patient level. For example, the cost accounting module can integrate with payroll systems and report on labor variance using labor productive hours and dollars. Questions 1 Do you think standards can be applied to procedures in hospitals? 2 Do you think standard cost variance reports are useful in healthcare?
