In services where teams come together for short collaborations, managers are often advised to strive for high team familiarity so as to improve coordination and, consequently, performance. However, inducing high team familiarity, by keeping team membership intact, can limit workers'...

Early diagnosis of HIV among infants born to HIV infected mothers is critical because roughly 50% of untreated infected infants die before the age of two years. Yet most countries in sub-Saharan Africa experience significant delays in diagnosis due to operational inefficiencies in early infant...

Several Emergency Medical Service (EMS) agencies across the US have demonstrated that the time spent by EDs on ambulance diversion can be reduced by implementing community-wide policies that restrict the duration and frequency of diversion episodes. However, the mechanisms through which these...

There is increasing evidence that workers in many service settings regulate their work speed in response to operating conditions. However, in service episodes of finite duration characterized by time-varying and non-stationary dynamics (e.g., outpatient departments), operating variables that can...

We analyzed the planning problem for HIV screening, testing and care. This problem consists of determining the optimal fraction of patients to be screened in every period as well as the optimum staffing level at each part of the health care system to maximize the total health benefits to the...

Virtual appointments between patients and healthcare providers (through phone calls, e-mail and web based applications) can provide a cost-effective alternative to traditional office appointments for managing chronic conditions via regular monitoring, symptomatic treatment and education. Virtual...

Problem Definition: Healthcare systems in resource-limited settings rely on diagnostic networks in which medical samples (e.g. blood, sputum) and results need to be transported between geographically dispersed healthcare facilities and centralized laboratories. Due to lack of updated...

Early infant diagnosis (EID) programs in many resource-limited settings are aimed at diagnosing infants born to HIV positive mothers. Due to the complexity of the diagnostic technology, EID programs are often highly centralized with few laboratories testing blood samples from a large network of...

This paper studies a model of community-based healthcare delivery for a chronic disease. In this setting, patients periodically visit the healthcare delivery system, which influences their disease progression and consequently their health outcomes. We investigate how the provider can maximize...
