This document discusses using computer science applications to improve health delivery in low-income countries. It provides two examples: 1) patient record systems using electronic medical records to track AIDS treatment in Rwanda, and 2) using medical algorithms on handheld devices to standardize child healthcare through automated Integrated Management of Childhood Illness protocols in Tanzania. Both aim to improve adherence to treatment guidelines, data quality, and clinical decision making. The conclusion emphasizes that any such applications must understand the local context and face challenges of evaluation, local ownership, integration, and avoiding duplication of existing efforts.
