[Excerpt from publishers] We, the representatives of more than 25 million health professionals, are committed to providing safe, accessible health care to the world's people. We understand all too well the impact of shortage of personnel, supplies and equipment on patients, families and providers. We witness the impact daily of not enough staff, not enough clean water, not enough drugs, not enough money to access services or to afford life's staples. We see health professionals mentally and physically exhausted daily. We struggle with the dilemma of resource restrictions and meeting the needs of everyone - and the evidence that shows that better health outcomes occur when higher numbers of professionals are engaged in direct care. We understand the need to address today's human resource crisis. At the same time we are concerned that task shifting and adding new cadres of workers result in fragmented and inefficient service through reductionist and vertical approaches.
