Often a life threatening emergency, it mandates prompt assessment and intervention. Various investigations and management protocols are proposed globally, to advocate a standardized approach towards patients presenting with hemoptysis. It is the etiology, however, that has been known to influence clinical outcome and prognosis. With marked contrast in geographical patterns of pulmonary pathologies, etiological agents for hemoptysis vary over the world. Studies in West, usually demonstrate neoplastic and non-granulomatous causes to be the leading agents for hemoptysis. The diagnostic accuracy of various investigations and efficacy of management alternatives has been established there. Developing nations differ in their burden of diseases of lung. Lack of health resources and initiative often prevent quality research in critical areas.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Design<\/jats:title>\n            <jats:p>This is a retrospective observational study with a cross-sectional design in which charts of all patients admitted with the presentation of haemoptysis in the past ten years will be reviewed, at Aga Khan University Hospital, Karachi, Pakistan. A series of variables, based on previous literature on haemoptysis related to the objectives of present study, will be determined in the study. Demographics, co-morbids and etiology will be determined. Findings of various investigation modalities and their accuracy in localizing the bleeding site will be determined. Efficacy of different management strategies will also be observed. Also observed will be any complications and follow-up.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Discussion<\/jats:title>\n            <jats:p>Pakistan is a third world nation of over 150 million, established as highly endemic for pulmonary tuberculosis. To date no study has been generated to look into hemoptysis patterns, in this nation. Lack of evidence based medicine poses a major hindrance towards confident decision-making in the approach towards a patient presenting with hemoptysis in this country. This study is devised to obtain the first insight in this direction, from this part of the world. The etiologies, accuracy of various investigations and efficacy of treatment options will be investigated. The results and conclusions will prove to be of value not just for health administrators in this country, but many other regions that share similarities in patterns of pulmonary pathologies.<\/jats:p>\n          <\/jats:sec>","DOI":"10.1186\/1471-2466-6-1","type":"journal-article","created":{"date-parts":[[2006,1,23]],"date-time":"2006-01-23T12:43:36Z","timestamp":1138020216000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":13,"title":["Hemoptysis, a developing world perspective"],"prefix":"10.1186","volume":"6","author":[{"given":"Omer","family":"Ashraf","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2006,1,13]]},"reference":[{"key":"40_CR1","doi-asserted-by":"publisher","first-page":"548","DOI":"10.1053\/rmed.2001.1053","volume":"95","author":"AT Abal","year":"2001","unstructured":"Abal AT, Nair PC, Cherian J: Haemoptysis: aetiology, evaluation and outcome \u2013 a prospective study in a third-world country.
