In a seminal examination of perioperative mortality in a cohort of American hospitals, Beecher and Todd (1954) document a twofold increase in death when these agents were used. However, as surgical interventions become increasingly available and surgical techniques advance, these medications have the potential to contribute to poor outcomes. Myocardial depression is a common side effect of anesthesia medications and can prove lethal in patients with underlying disease or those with hemorrhage or hemodynamic instability. Unfortunately, in these same settings, standard rescue medications, including epinephrine, are not routinely available to treat these predictable side effects. Evidence suggests that changes in the perioperative management initiated by anesthetists at the time of surgery can significantly reduce mortality related to these anticipated cardiac events (Canty and others 2012). Perioperative evaluation provides valuable information to providers planning optimal anesthesia management. An inexpensive screening test, such as hemoglobin measurement, contributes to improved outcomes. Ideally, the perioperative period should be used to alter or improve comorbidities and to improve perioperative health status. Pain management is not only basic to the right to health (MacIntyre and Scott 2010; Morriss and Goucke 2011; Size, Soyannwo, and Justins 2007), but inadequately treated pain contributes to morbidity and, in some rare cases, to mortality. Uncontrolled acute pain also increases the incidence of chronic pain (MacIntyre and Scott 2010), potentially imposing a degree of suffering and disability that may last for years. Overall mortality from anesthesia fell from 357 per million before the 1970s to 34 per million during 1990­2010, despite the growing number of patients with increased anesthetic risks. In comparison, the perioperative mortality in the United States in the 1950s was 1 in 1,500 (Beecher and Todd 1954). In each study, deaths from anesthesia were most commonly due to undetected hypoxia or hypovolemia. Inadequate equipment, training and supervision, and safety monitoring- particularly pulse oximetry-were cited as contributors to these poor outcomes. Several of these studies shared a similar methodology; despite being relatively small, they are important because of the consistently high rates of mortality reported. For example, 50 years of intense commitment in Australia has reduced avoidable anesthesia-related mortality from 1 in 5,000 to 1 in 100,000-and 1 in 180,000 in cases in which anesthesia is the sole cause of mortality and morbidity (Mackay and Cousins 2006). Information related to perioperative morbidity is more difficult to obtain because of the lack of postoperative care units and postsurgical patient follow-up. As the anesthesia and surgical resources of a country improve, gains in absolute perioperative mortality are likely to be reinvested in operating on patients with more serious conditions and comorbidities. Further gains will require exponentially greater investments, and progress might be more apparent in the increased acuity of patients taken to the operating room rather than in improved overall survival. The absolute cost of providing safe anesthesia is a complex equation that varies by country and is affected by market variables such as the required use of medical-grade equipment, nongeneric medications, and changing technology. Every variable, from the cost of training a physician anesthesiologist to providing oxygen, is affected by local access, government, and regional availability of resources. Until then, the most compelling analyses are those comparing general, regional, and local anesthesia for specific procedures (Borendal Wodlin and others 2011; Doberneck 1980; Duh and others 1999; Gonano and others 2009; Schuster and others 2005; Shillcutt, Clarke, and Kingsnorth 2010; Shillcutt and others 2013; Song and others 2000; Wilhelm and others 2006). These improvements have occurred in the context of a platform of professional education and training, clinical excellence, and professionalism. Safety innovation has not always occurred under circumstances of rigorous validation of efficacy and cost-effectiveness. The pulse oximeter, for instance, was rapidly embraced as mandatory safety technology and included as a required monitor for sedation and anesthesia by organizations and societies throughout the world; to date, however, it has not been evaluated for cost-effectiveness (Pedersen and others 2014). Costs of Adequate Resources and Patient Safety Safety measures since 1970 include the required vigilance of anesthesia providers, improved pharmacology to support hemodynamic stability, and safety monitoring to provide early warning of the common risks of anesthesia-hypoxemia, inadvertent esophageal intubation, and cardiac depression. Electricity must be available and energy costs must be considered for operating a concentrator.

Task-sharing has also been promoted, with nonspecialist doctors and nonphysicians increasingly filling a deficit in medical services (Scott and Campbell 2011) and emergency obstetric care (Ejembi and others 2013; Kruk and others 2007; Sitrin and others 2013). Unlike many global health interventions, surgery is a relatively nebulous service with indistinct borders. As a result, it is often provided by disparate, poorly organized platforms (Shrime, Sleemi, and Thulasiraj 2014). This model proved to be well calibrated to current health outcomes in Ethiopia (Shiferaw and others 2013). The results of this analysis explicitly illustrate tradeoffs between health and financial risk protection.

The health benefits accrue preferentially to the wealthiest, whereas the financial burden falls on the poor, in part because the rich, in this model, tended to be more sensitive to a lack of provider than to price. Much of the impoverishment created occurs because, although demand for surgical services is induced by their new availability, these services are not always free, and patients still have to pay for the nonmedical costs of obtaining care. For many patients, these costs prove catastrophic (Kowalewski, Mujinja, and Jahn 2002). Poverty is no longer created, but because these policies are significantly more expensive, the amount of health benefit achieved per dollar spent drops drastically. How such tradeoffs are to be handled is less clear and necessitates further substantial ethical and patient-preference analyses. Although the cost per quality-adjusted life year cannot be calculated using the methodology employed here, a rough approximation using the median age in Ethiopia of 16. Although the base-case analysis did not include the start-up costs of a task-sharing program, adding these costs (Kruk and others 2007) decreased the amount of any benefit bought per dollar by task-sharing policies but had a minimal impact on the distributional pattern for health and financial benefits. We used an oftenemployed head-count approach to measuring impoverishment (Garg and Karan 2009; Habicht and others 2006; Honda, Randaoharison, and Matsui 2011; Niens and others 2012). Some authors, however, suggest that a movable threshold (Ataguba 2012) or measures of depth of poverty (Garg and Karan 2009) are more appropriate. We model the former in annex 19A, and the distributional patterns of health and financial risk protection benefits remain essentially unchanged. It should be noted, however, that the latter measure of poverty makes impoverishment in the poorest quintile much more explicit. In the method presented above, individuals in the poorest quintile all fall below the national poverty line. No poverty can be created or averted in these individuals because of that-an artifact which explains the fact that no cases of impoverishment occur in the poorest in table 19. The impoverishing impact of each policy on the poorest quintile is, therefore, best seen in annex 19A. This method is also limited in that it does not measure counterfactual impoverishment well. Were a breadwinner to suffer a catastrophic health event, that death 348 Essential Surgery may throw an entire household into poverty. This is not explicitly addressed in our current analysis and is left to future inquiry. In addition, the distribution of these benefits depends on the policy chosen: on the one hand, making surgery free at the point of care appears primarily to improve financial risk protection among the richer segments of the rural Ethiopian population. Conversely, task-sharing without vouchers creates cases of poverty while averting deaths across the entire population; the latter benefit primarily accrues to the richest, while the former harm accrues to the poorest. Because these are initially counterintuitive findings, the model was tested with multiple sensitivity analyses, including the following: allowing the demand function to be more price elastic, including the costs of start-up for a task-sharing program; increasing the probability of dying from untreated disease; decreasing the direct nonmedical cost; increasing the cost of complications, including indirect costs in three separate ways; and modeling the effect of taxation to pay for the proposed policies. Although the magnitude of the benefits bought per dollar changes with these sensitivity analyses, the changes are often small. More important, except in the case of taxation, the distribution of the benefits across wealth quintiles is robust to these sensitivity analyses.

A randomized trial demonstrated a recurrence rate of only 1 percent to cholesterol without fasting purchase lipitor on line 2 percent with the Lichtenstein technique (Fitzgibbons and others 2006) cholesterol levels gcse order lipitor with mastercard. Although some studies suggest that the mesh technique may increase the risk of chronic postoperative groin pain cholesterol in cage free eggs purchase lipitor 40 mg on-line, the results of the Lichtenstein repair represent a significant improvement over traditional tissue repair (Hakeem and Shanmugam 2011). First described in 2001, the Desarda repair, which uses an undetached strip of external oblique aponeurosis to reconstruct the posterior wall of the inguinal canal, is an example of a tension-free tissue repair. This technique has been shown to have rates of recurrence and postoperative pain similar to that of the Lichtenstein technique (Szopinski and others 2012). Although the risk of postoperative complications is slightly higher after laparoscopic repair, laparoscopy is associated with decreased recovery time and less postoperative pain than open mesh techniques (McCormack and others 2003; Neumayer and others 2004). Cost-effectiveness studies comparing laparoscopic with open inguinal hernia repair techniques have been inconclusive (Heikkinen and others 1997; Schneider and others 2003). However, a report from Nigeria found that the mesh repair was well tolerated, with few complications at one-year follow-up (Arowolo and others 2011). A study from Uganda comparing patients randomized to receive the Desarda tension-free tissue hernia repair and the Lichtenstein mesh repair demonstrated similar short-term clinical outcomes. Of note, the operating time for the Desarda repair was shorter in this study (Manyilirah and others 2012). Open inguinal hernia repair may be performed using local, spinal, or general anesthesia, depending on both patient status and surgeon preference. However, spinal and general anesthesia are associated with higher rates of myocardial infarction and urinary retention, respectively, in patients older than age 65 years (Bay-Nielsen and Kehlet 2008). No pulse oximeters were found in any of the 14 government hospitals surveyed in a study from Uganda (Linden and others 2012). Mosquito netting has been introduced as a prosthesis for inguinal hernia repair to address the high cost of industry mesh. In the 1990s, sterilized mosquito-net mesh was first used to repair inguinal hernias in India. Tongaonkar and others (2003) reported a series of 359 hernias that were repaired with a copolymer mosquito-net mesh (polyethylene and polypropylene) in multiple hospitals throughout India. On short-term follow-up, the minor wound infection rate was less than 5 percent; there were no mesh infections and one hernia recurrence. These promising preliminary findings in India have prompted further investigation into the use of noninsecticide-treated mosquito-net mesh for inguinal hernia repair in other low-resource settings, specifically, Africa. The feasibility and safety of this technique have been demonstrated for nylon and polyester mosquito-net mesh in Burkina Faso, Ghana, and India (Clarke and others 2009; Freudenberg and others 2006; Gundre, Iyer, and Subramaniyan 2012). In addition, experimental research in goats has shown that nylon mesh leads to a similar amount of tissue fibrosis when compared with standard polypropylene industry mesh (Wilhelm and others 2007). Effective sterilization techniques have been described for both copolymer and polyester mosquito-net meshes (Stephenson and Kingsnorth 2011). Newer studies have investigated the molecular characteristics and associated infection risk of mosquito-net mesh compared with commercial hernia prosthetics. In one study, Sanders and others (2013) inoculated polyethylene mosquito-net and industry meshes with staphylococcus epidermidis and staphylococcus aureus. They found no difference in the mean number of adherent bacteria to mosquito-net mesh when compared with commercial polypropylene-based meshes. These results suggest that implantation of mosquito-net mesh should not increase the risk of surgical site infection. Sanders, Kingsnorth, and Stephenson (2013) investigated the macromolecular structure of polyethylene mosquito-net mesh using electron microscopy and spectroscopy, demonstrating that the material and mechanical properties of mosquito net, including tensile strength, are equivalent to those of common lightweight commercial meshes. Although the results of these studies are promising, sample sizes are small and follow-up is limited. Further investigation into the efficacy and safety of mosquito-net mesh for inguinal hernia repair is needed before widespread implementation. Potential challenges to widespread implementation include inadequate training in the mesh technique, barriers to acceptance of mosquito netting as a surgical tool by care providers, and complexities of acquisition and distribution of the mosquitonet mesh. Another important and increasingly recognized complication is chronic postoperative groin pain. Postoperative pain syndrome may occur in up to 53 percent of patients and is often difficult to prevent and treat (Poobalan and others 2003). Primatesta and Goldacre (1996) observed the rate of postoperative deaths following elective and Hernia and Hydrocele 157 Box 9.
