Key chllenges tht remin re overcoming the wekness of strtegy built on cse mngement, sustining commitment, competing priorities, the thret of HIV, mintining high qulity of cre nd preventing drug resistnce, building humn resource cpcity, improving dignosis nd fostering opertions reserch. The bility to ddress these chllenges will determine the success or filure of the Globl Pln to Stop TB, Bulletin of the World Helth Orgniztion 2007;85: الرتجمة العربية لهذه الخالصة يف نهاية النص الكامل لهذه املقالة. espñol.

Al finl del rtículo se fcilit un trducción l Introduction The recent Globl Pln to Stop TB, tkes into ccount the chllenges identified during the five yers of the Globl DOTS Expnsion Pln (GDEP), which rn from 2001 to At workshop in Ciro in November 2000, ntionl TB progrmme (NTP) mngers from the 22 high-burden countries, WHO, technicl prtners, development gencies nd donors greed to develop the GDEP in response to the Amsterdm Declrtion nd resolution of the World Helth Assembly (WHA) in My The focus of the GDEP would be to estblish ntionl DOTS expnsion plns nd develop prtnerships to control TB. Prticipnts t the workshop identified nine key res of work s criticl to chieving the gols of the Amsterdm Declrtion nd the WHA resolution development of five-yer plns, incresed politicl commitment, enhnced ntionl nd interntionl prtnerships, socil mobiliztion, humn resource development, improved TB drug procurement, qulity ssurnce of smer exmintion nd opertionl reserch to improve TB control. Mjor progress hs been mde since tht time, including: 3 vibrnt interntionl Stop TB prtnership; severl progrmmes with ntionl TB prtnerships; ntionl DOTS expnsion plns in ll high-burden countries; the Globl TB Drug fcility (GDF); sustined interest of interntionl policy-mkers; mobiliztion of substntil finncil resources through estblished mechnisms (e.g. development gencies) nd new mechnisms (e.g. the Globl Fund for AIDS, TB nd Mlri); commitment of ntionl public uthorities to doption nd dpttion of interntionl policies; implementtion of cse mngement in routine helth services; nd incresed support for development of new dignostics, drugs nd vccines. However, key chllenges remin nd my not hve been sufficiently ddressed in the GDEP. This pper discusses these chllenges. Wekness of the core strtegy Prevention bsed on cse mngement hs never eliminted or erdicted ny disese only vccine-bsed strtegies hve chieved this. 4 Situting prevention in cse mngement (i.e. in routine helth services) mens tht ll the chllenges of estblishing nd mintining qulity helth services (e.g. ccess, equity nd competing priorities) must be fced. The focus on downstrem interventions prioritizes cse mngement nd even the ppliction of the currently vilble vccine (which prevents serious forms of disese in smll children but hs not been demonstrted to prevent primry infection). 5 This pproch fils to ddress fctors relted to poverty, with which TB is intimtely ssocited. Sustining ownership nd empowerment In fighting TB, economic rguments hve been used to engge key stkeholders. These rguments re bsed on the reltive cost-effectiveness of the interventions nd the economic gins to be mde from following the strtegy. For exmple, the World Bnk promoted the view tht governments could not fford not to implement DOTS. 6 Although this pproch hs been successful in certin loctions, bilterl nd multilterl gencies hve sometimes undermined the economic rgument by shifting responsibility for budgets for TB control from ntionl to interntionl sources. 7,8 Ownership of the domin hs consequently been tken up by interested prties t n interntionl level, rther thn by those primrily ffected. This sitution tends to disempower locl nd ntionl stkeholders. Addressing competing interests nd fshions Helth services worldwide hve limits on their resources, prticulrly where resources re scrce. Also, resources re not lwys llocted ccording to evidence, especilly in poor nd mrginlized communities. 9 Rther, they re often subject to specil interests nd fshions in the re of interntionl development policy, with the only stble fctor in such policy being the desire to chnge it. The exmple of WHO reflects this tendency. When formed, the orgniztion Interntionl Union Aginst Tuberculosis nd Lung Disese, 68 boulevrd Sint-Michel, Pris, Frnce.

2 Criticl evlution of the Globl DOTS Expnsion Pln Donld A Enrson & Nils E Billo included specilized TB unit. 10 Efforts in TB control coincided with stedy declines in TB mortlity nd morbidity in industrilized countries. 11 However, similr progress ws not observed in low-income countries, nd the pproch ws hevily criticized. 12 A subsequent shift of emphsis from specilized to generlized primry cre services followed the doption of the slogn Helth for ll by the yer As the yer 2000 pproched, however, this slogn disppered, nd trgeted pproches (to TB, mlri, tobcco nd other specific issues) emerged nd gined high visibility. If fshions chnge, will it be possible to provide the decdes of commitment required to chieve the GDEP s gols? Stemming the tide of HIV In some countries, prticulrly in southern sub-shrn Afric, TB nd HIV re closely linked; for exmple, in the highest-burden settings, 75% of TB ptients re lso living with HIV/AIDS. 14 Due to the link between TB nd HIV, sub- Shrn Afric is likely to supersede ll other regions in the burden of TB over the coming decdes. 15 The trend of rising TB cse rtes cn only be reduced if HIV infection rtes re lso reduced. The Stop TB Prtnership (the orgniztion tht developed the GDEP) nd its TB/HIV working group recognize this sitution, but not ll current pproches ddress the chllenge. Filure to link efforts in TB control to those imed t reducing HIV infection rtes will undermine ll other efforts to stop TB. Mny countries hve ttempted to improve collbortion between TB nd HIV services, but progress hs been pinfully slow nd indequte. 16 Mintining service qulity, preventing drug resistnce The qulity of cre for TB ptients is inextricbly linked to the future of the TB epidemic. 12 By keeping ptients live but filing to cure them, poor tretment ctully ugments the spred of TB. Also, high proportion of previously treted cses hrbour drug-resistnt bcilli nd trnsmit infection in the community. 17,18 Recently, there hve been outbreks of extensively drug-resistnt (XDR) TB, even in loctions tht hve supposedly dopted interntionl recommendtions for stndrd cse mngement. 19 Access to second-line medictions nd improper use of these medictions hs not prevented, nd my even hve promoted, these outbreks. It is uncler how much the rther strict conditions of the DOTS strtegy cn be liberlized without dverse consequences. Wht is cler is tht, in loctions where the rther old-fshioned strict policies hve been conscientiously followed (e.g. United Republic of Tnzni, 20 Benin 21 nd Nicrgu 22 ), the numbers of multidrug resistnt (MDR) cses re low; wheres, in situtions where only some elements of the strtegy hve been strictly dopted, MDR- 23 nd XDR-TB 19 hve emerged. These finding suggest tht strict policies re crucil in preventing emergence of drug resistnce. Such considertions hve prticulr relevnce where stndrd cse mngement is provided in multiple sectors, prticulrly the privte sector, where qulity of services repetedly hs been shown to be deficient. 24,25 Cn the qulity of such services be improved? And if so, cn improved qulity be sustined? In other conditions (e.g. sthm), stndrd cse mngement (i.e. cre bsed on guidelines) hs been demonstrted to be the mngement of choice (i.e. the best stndrd of cre), but lthough professionl bodies nd specilists subscribe to the theory, they rrely crry it out in prctice. 26 Efforts to improve qulity of cre within the privte sector hve been initited within WHO s Stop TB Deprtment; for exmple, through the publiction of the Interntionl Stndrds for Tuberculosis Cre. 27 Also, some studies suggest tht qulity of cre cn be improved through trgeted interventions to encourge prtnership. 28,29 Ensuring the consistent delivery of high-qulity of cre t ll levels of the helth service nd within ll sectors will be key chllenge. If the GDEP pln (or the more recent Globl Pln to Stop TB) hs not sufficiently ddressed this point, it will be mjor chllenge to the strtegy. Ensuring sufficient humn resource cpcity The GDEP succeeded in mobilizing dditionl resources from vriety of sources, nd mny countries hve been ble to expnd DOTS ccording to their 5-yer plns, often creting intergency committees to improve coordintion between the vrious stkeholders. Improving coordintion, voiding dupliction of efforts nd voiding giving conflicting recommendtions will continue to be chllenge for ll prtners. Tody, NTP mngers spend much of their time writing funding proposls, prepring reports (in different formts for ech donor) nd orgnizing review visits for their multitude of prtners. NTP mngers nd progrmme stff need to hve enough time for ctivities criticl to improving TB control. The Ciro workshop identified the need to increse politicl commitment to secure dequte humn resources nd finnces for ll TB control components t ntionl nd sub-ntionl levels. 30 Substntil funding hs been obtined from mny donors in prticulr from the Globl Fund. 31 However, mny countries still find it difficult to implement effective humn resource development strtegies nd to secure sufficient funding for this purpose. 32 Although trining courses re offered t ntionl nd interntionl levels, countries re struggling to retin qulified personnel. For exmple, qulified nd well-trined stff often seek employment in the privte sector or in interntionl bodies, or migrte to industrilized countries. 33 Provision of dditionl funding cn overwhelm some countries, prticulrly where bsorption cpcity is hmpered by indequte mngement systems. 34 Thus, reinforcement nd mintennce of humn resource cpcity in technicl nd mngement domins probbly represents the min chllenge for TB control in the next decde. Assuring qulity of dignosis Estblishment nd implementtion of qulity ssurnce for dignostic exmintion (sputum-smer microscopy) ws one of the GDEP s min gols. This bsic test, which should be techniclly fesible t ny loction, is fundmentl to TB dignostic service. Gret progress hs been mde in estblishing globl consensus on methods for qulity ssurnce of sputum-smer microscopy, 35 nd group of experts hs been set up to develop improved tools nd strtegies for dignostic services. 36 In spite of these dvnces, the qulity of sputum-smer exmintion remins deficient in mny (if not most) sites, nd recommended progrmmes for qulity ssurnce hve not been widely implemented. 37 Current dignostic procedures remin cumbersome nd time-consuming. 396 Bulletin of the World Helth Orgniztion My 2007, 85 (5)

3 Donld A Enrson & Nils E Billo Specil theme Tuberculosis control Criticl evlution of the Globl DOTS Expnsion Pln Confirming dignosis by definitively demonstrting the presence of Mycobcterium tuberculosis continues to tke dys or weeks, nd even sputum-smer microscopy my necessitte visits to helth fcilities over severl dys. The need for, nd benefits of, new technology tht cn provide on-the-spot, relible dignostic tools re obvious. Mintining criticl spirit A climte of criticl reflection is necessry for effective nd efficient public helth. 38 This cn be chieved through n imbedded progrmme of opertions reserch (nother plnk of the GDEP nd importnt in the first formultion of the NTP s idel structure). 39 Although studies from limited number of loctions hve been published over the pst decde, the estblishment nd mintennce of opertions reserch is rrely routine ctivity within NTPs. Implementtion of routine stndrdized monitoring of dignosis nd tretment outcomes using cohort nlysis hs helped to improve NTPs qulity of services, 43 nd hs provided vluble informtion for opertionl plnning nd mngement. Clerly, the GDEP nd the Globl Pln to Stop TB hve mde gret strides towrds reducing the huge burden to helth cused by TB, but much more remins to be done if we re to overcome the chllenges discussed here.

5 Round tble discussion Round Tble Discussion Public privte mix DOTS in Indi LS Chuhn The bse pper highlights the chllenge of mintining the qulity of TB services while working with multiple sectors, nd this discussion is very relevnt to the Indin setting. Despite hving lrge network of stte government-owned public helth fcilities, significnt proportion of Indin ptients seek helth cre from the privte sector. 1 Numerous nongovernmentl orgniztions (NGOs) provide TB services. Moreover, mny lrge nd smll stte nd ntionl public-sector providers including rilwys, socil insurnce, ports, mines nd the rmed forces lso mnge lrge numbers of TB ptients but re not under the direct purview of the Revised Ntionl TB Control Progrmme (RNTCP). To ddress this, the RNTCP piloted nd documented innovtive public privte mix DOTS (PPM DOTS) models during the erly phse of expnsion. Evlution of these models provided evidence for dditionl TB cse detection with good tretment success rtes. 2 Subsequently, the RNTCP recognized PPM DOTS s strtegy to mnge TB ptients reporting to multiple sectors nd different types of helth-cre providers. From s erly s 2002, RNTCP hd expnded PPM DOTS ctivities country-wide using the progrmme guidelines for involvement of NGOs nd privte prctitioners. 3,4 The strtegy is built round developing DOTS tsk mix for ech provider type, with the RNTCP offering support for tsks tht the relevnt provider is unble to perform, such s defulter retrievl or lbortory qulity ssurnce. For medicl college involvement, stte-level nd ntionl tsk forces were creted. In 2003, the RNTCP lunched intensified PPM DOTS ctivities in 14 urbn districts. WHO-PPM medicl consultnts nd peripherl field supervisors were recruited nd posted to these districts. An expnded version of the existing routine RNTCP surveillnce system collected disggregted dt from the different helth-cre providers. Providers were involved through systemtic process of situtionl nlysis nd listing of helth-cre fcilities, sensitiztion nd trining of prctitioners on RNTCP, trining of RNTCP stff on PPM-DOTS, identifiction of fcilities for RNTCP service delivery, memornd of understnding nd RNTCP service delivery. The dt from the intensified PPM sites hve shown n overll increse in the number of TB cses notified under RNTCP. The stte government public helth deprtments remin the lrgest contributors to cse detection, followed by medicl colleges nd the NGO sector. The yield of cses from the privte sector to RNTCP hs not been proportionte to the numbers involved. This is becuse there re numerous privte clinics nd hospitls in urbn res which usully hve very low TB ptient lods. NGOs nd privte prctitioners contribute more to tretment observtion thn to cse detection. These findings hve highlighted nd reinforced the importnce of initilly prioritizing nd trgeting PPM-DOTS ctivities for those fcilities used by the lrgest numbers of ptients. The intensified PPM-DOTS ctivities strengthened the wider government helth sector s involvement in the progrmme, leding to incresed cse detection from this sector. Economic evlutions in Hyderbd, New Delhi nd Bnglore show tht PPM-DOTS is ffordble nd cost-effective, nd tht it reduces the finncil burden on ptients nd society. 5,6 Another evlution in Bnglore shows tht the intensified PPM inititive hs predominntly reched people from lower socio-economic groups. 7 Thus, lthough demnding in terms of efforts required, PPM DOTS is essentil in the longterm interests of ptients, providers nd progrmmes. Currently more thn privte prctitioners, over 2000 NGOs, over 230 medicl colleges nd 110 corportesector helth fcilities re involved in RNTCP ctivities. The Indin Medicl Assocition is n importnt prtner of RNTCP t ntionl nd stte levels, nd hs dopted the Interntionl Stndrds for TB Cre. As the bse pper s uthors point out, RNTCP is wre tht dopting stndrds lone my not led to improved mngement prctices. This will require continuous enggement nd working in prtnership with the diverse providers. Building on their chievements, the RNTCP nd the Indin Medicl Assocition re working together to implement the PPM component of project recently pproved by the Globl Fund to Fight AIDS, Tuberculosis nd Mlri.

6 Round tble discussion As high-burden country, the Philippines prticipted in ll three milestone events. The story of DOTS implementtion in the country hd begun five yers before, when the WHO Regionl Director for the Western Pcific Region nd the newly ppointed Philippine Secretry of Helth greed in mid-1995 to give priority ttention to tuberculosis by llocting t lest hlf of the country s WHO funds (roughly US$ 2 million per biennium) to initite mjor TB control effort. By mid-1996, 16 out of the country s 77 provinces were selected s pilot sites. From the strt, the NTP hd to del with the dministrtive difficulties introduced by 1992 lw trnsferring responsibility for helth services to locl governments. By 1995 the Deprtment of Helth hd devolved control of helth service units to 77 provinces nd over 1600 cities nd municiplities. Nevertheless, the NTP s well-motivted, techniclly competent nd well-mnged stff ws ble to strt up the DOTS strtegy in ll 16 selected sites in less thn two yers. Lerning from the experience of other ntionl progrmmes, like immuniztion nd fmily plnning, NTP developed mechnisms to work with locl government units to implement its ctivities. Results of the Ntionl TB Survey of 1997 confirmed tht the Philippines, with n estimted prevlence of lmost hlf million cses, still hd mjor TB problem. This provided the impetus for ntionwide implementtion of the DOTS strtegy, which ws expnded strting in By the end of 2000, the Philippines reported 100% DOTS coverge. Menwhile, nlysis of ntionl helth expenditures led to helth sector reform gend tht significntly stremlined DOH opertions, beginning with the centrl office. In the ensuing centrl office stff reductions, NTP positions were reduced from 22 to 2 in However, subsequent stffing review enbled the restortion of 7 posts. Additionlly, NTP trined regionl helth office stff, who work closely with locl governments. NTP s 2000 dt showed tht DOTS ws implemented throughout the country, tht its tretment success rte ws 88% nd its cse detection rte ws 48%. To improve cse detection, NTP strengthened its links with the Philippines Colition Aginst Tuberculosis (n NGO of privte individuls nd institutions) by developing the public privte mix (PPM) DOTS pproch. The Ntionl Helth Insurnce Progrmme lso included implementtion of DOTS strtegy in its benefits pckge. DOTS thrives tody, thnks to locl nd ntionl politicl commitment, the support of WHO-WPRO, funding from the Globl Fund to Fight AIDS, Tuberculosis nd Mlri nd the introduction of the Globl Drug Fcility for procurement of DOTS supplies. It hs met the globl trgets with 75% cse detection nd 87% success rtes. Nevertheless, some concerns persist, such s whether such levels of commitment nd support cn be mintined for nother decde. Additionl concerns include the possible emergence of uncontrolled multidrugresistnt strins of TB nd increses in wht is now low nd slow HIV/AIDS sitution in the Philippines. A finl concern is whether the Ntionl Helth Insurnce Progrmme, pivotl in helth-cre finncing reform, cn expnd its coverge of the DOTS strtegy fst enough to cover nticipted reductions in externl support beyond O Lessons from the DOTS Expnsion Pln in Indonesi: highlighting humn resource development Crmeli Bsri, Petr Heitkmp b & Firdosi Meht b Indonesi rnks third mong the TB high-burden countries. A decde of TB control using the DOTS strtegy hs fcilitted progress towrds reching the 2005 interntionl trgets for TB control. Indonesi reported cse detection rte of 68% for 2005 nd success rte of 87% for the 2004 ptients cohort. The strong politicl commitment nd ledership shown by the Indonesin government from 1999 onwrds hve led to the development of tody s TB control strtegy. This commentry highlights three key pillrs towrds the chievement of the 2005 trgets. First, sound nd well-budgeted five-yer strtegic pln, 1 following the Globl DOTS Expnsion Pln s explined in Enrson & Billo s pper, lid the foundtion for implementtion nd ttrcted donor funding, including two grnts from the Globl Fund to Fight AIDS, Tuberculosis nd Mlri (Globl Fund). Second, the NTP focused on humn resources development nd cscded trining through bilterl donor grnt. The cscded trining progrmme, which strted in lte 2000, llowed trining of different ctegories of stff. During the biennium , over 5000 (34.7%) doctors nd nurses t the helth-centre level were trined out of the totl pool of trinees estimted t The helth ministry reports tht 98% of TB stff t helth centre fcilities nd pproximtely 24% of TB stff t hospitls re trined in DOTS. A core of mster triners t the regionl level initited nd supervised the plnning nd coordintion of trining ctivities. Trining ctivities were grdully shifted to the districts fter centrl trining group ws estblished to ct s ctlyst nd reference point in ccordnce with guidelines nd curricul. 2 Through the Globl Fund funding, s prt of the overll humn resource development pln, tems of mobile mster triners helped cler the trining bcklog t the helth-centre level. In ddition, trining coordintors re in plce t the NTP nd in most provinces. Third, mngement cpcity hs been strengthened t ll levels, with key inititive to estblish provincil DOTS tems s well s to decentrlize the Globl Fund mngement to district level. The Globl Fund hs cted s pull mechnism for improving surveillnce nd informtion flows. Indonesi is moving forwrd in implementing the new five-yer pln for TB control 3 in line with the new Stop TB Strtegy. The 2004 prevlence survey 4 shows lrge geogrphicl difference in TB burden, reflecting the need for re-specific plnning, including doption of the Interntionl Stndrds for TB Control (ISTCs) mong ll helth-cre providers. This lso ddresses the chllenge of TB/ HIV in ffected provinces, nd prevents multidrug-resistnt TB by strengthening lbortory networks nd surveillnce. The involvement of ll helth-cre providers in Jv nd Bli prioritizes linkges between hospitls nd helth-cre centres.

Mny inconsistencies remin in trnslting these TB policies into locl plns nd budgets; fostering locl government commitment is relted chllenge.

They did not, however, elborte on one of the key chllenges the low percentge of infectious tuberculosis (TB) ptients identified nd treted in DOTS progrmmes. In this report, we describe key intervention tken by Chin to ddress this importnt problem. In 1992, Chin begn wide-scle implementtion of wht eventully becme known s the DOTS strtegy. In the hlf of Chin tht implemented this strtegy, the TB tretment success rte rpidly exceeded 85%. 1 However, during the 1990s, the TB cse-detection rte only reched 30% ntionwide. 2 The reson for the low cse-detection rte ws well known within Chin. Over 90% of ptients confirmed to hve TB initilly ccess cre in Chin s vst hospitl system, but less thn 30% of these ptients eventully end up in the Center for Disese Control nd Prevention (CDC) system where DOTS ws implemented. 3 Becuse most hospitls dignose TB using only chest X-rys, it cn only be confirmed fter evlution by the CDC, where sputum exmintion is lso used. In 1996, the Ministry of Helth (MOH) set up regultion requiring ll hospitls to report nd refer suspected TB ptients nd cses identified in these institutions to the CDC system for further follow-up. But this regultion proved difficult to enforce, becuse it ws difficult to monitor whether hospitls were in fct reporting nd referring ll their TB cses nd suspected cses. In 2003, the SARS epidemic broke out in Chin. The epidemic brought to light weknesses in the public helth system, especilly the problem of incomplete nd delyed reporting of SARS nd other communicble diseses. Following SARS, the government worked to improve the reporting of communicble diseses, revising the Lw on Controlling Infectious Diseses nd mking it legl requirement to report ll cses of 37 communicble diseses. 4 In Jnury 2004, the MOH lunched the ntionwide internet-bsed communicble disese reporting system. 5 By the end of 2005, 93.3% of helth fcilities t nd bove the county level nd 66.1% of township-level helth fcilities were using this system to report the country s 37 notifible diseses. The verge length of time to report from county-level helth fcility to the centrl level hs been reduced from 29 dys to 1 dy. The MOH hs instructed ll locl CDCs to regulrly visit hospitls t nd bove the county level nd to monitor the reporting nd referrl of suspected nd confirmed TB cses. As result, the number of these cses nd suspected cses reported by hospitls hs incresed. Hospitls re required to refer ll ptients suspected of hving TB or dignosed with it to the locl CDC for further evlution nd tretment. Some referred ptients report to the locl CDC nd some do not. Although the bsolute number of referred ptients coming to the locl CDC hs incresed over time, the percentge of ptients rriving on their own hs not. Every working dy, CDC stff members cross the country ccess the centrl dtbse to collect informtion on recently reported confirmed or suspected TB cses in their re. These stff members seek to contct ptients who fil to come to the locl CDC within three dys of being reported. In 2005, confirmed or suspected TB cses were reported from the hospitl system. Among them, (44%) cme to the CDC system by themselves for further evlution. Of the remining ptients, the CDC ttempted to contct (73.5%) of them, nd successfully found nd evluted ptients (or 47.4% of those sought for follow-up). Overll, (63.5%) of ll ptients reported by the hospitl system were eventully evluted by the CDC system. In 2005, Chin chieved the globl tuberculosis control trget of 70% cse-detection nd 85% tretment success. Of the smer-positive tuberculosis cses reported in 2005, (22.6%) were initilly reported by hospitls through the Internet. Thus implementtion of the system nd policies mentioned bove hs plyed n importnt role in tuberculosis cse detection. Nevertheless, to ensure tht even more ptients benefit from DOTS services, more work is needed to ensure tht higher percentge of referred cses get to the CDC before they re followed up, higher percentge of ptients re followed up, nd higher percentge of those who re followed up ctully rrive t the CDC system.

8 Round tble discussion Building politicl commitment in Peru for TB control through expnsion of the DOTS strtegy Cesr Bonill & Jime Byon b In the context of public helth, Peru hs long history in the fight ginst TB. 1,2 In 1990, the Ntionl TB Control Progrm becme ntionl helth priority, receiving government support to estblish progrmme tht hs been model of efficiency t the globl level. 1 Mintining TB s sttus s ntionl helth priority requires significnt level of politicl commitment, s the bse pper noted. 3,4 However, in country like Peru where the helth sitution is closely relted to constnt chnge nd rpid socil trnsformtion, n importnt element in ensuring politicl commitment is positioning the Ntionl TB Control Progrm s the key plyer in TB mngement. This effort s bsic principles must be communicted to dministrtive, politicl nd finncil decision-mkers. Politicl commitment for TB control must be sustined despite chnging heds of government nd fluctuting politicl trends. An importnt element in ensuring politicl commitment lies in the prticiption of civil society nd TB ptient orgniztions in ll levels of TB control ctivities, including humn rights issues. 4 When ntionl priorities shift nd ttention is deflected, TB control efforts cn suffer. 3 This is exemplified by the negtive impcts tht resulted from helth sector reform efforts erly in the current decde. 5 Until pproximtely 2001, Peru ws on the pth to exceeding its Millennium Development Gols regrding TB control. In , the helth reform process cused deteriortion in TB cse-detection ctivities. 5 Since 2004, this trend hs been reversed, yet we must now redouble our efforts to chieve the Millennium Development Gols. We gree with the led rticle s comments relting to mintining qulity of services, nd the Peruvin experience shows tht expnsion of the DOTS strtegy hs lso llowed us to successfully identify nd intervene in high vulnerbility res with elevted risk of tuberculosis trnsmission. These res include the prison popultion, the mrginlized urbn popultion in extreme poverty, indigenous popultions, those with MDR-TB nd others co-infected with HIV. In 2004, the Ntionl TB Control Progrm ws strengthened by four functionl pillrs: coordintion, mngement, communiction nd coopertion. These entities ll shre the responsibilities of mngement, ledership nd ccountbility. To further ensure politicl commitment, technicl committee (from government offices of finnce nd logistics) nd n dvisory committee (NGOs, technicl nd finncil institutions, scientific nd cdemic institutions) were set up s essentil prts of the Ntionl TB Control Progrm. This type of prtnership hs been crucil in securing politicl commitment, s civil society nd the Ministry of Helth hve joined efforts to work s tem by shring ledership nd responsibility nd integrting ctivities under new orgniztionl culture. These politicl commitments come not only from the Ministry of Helth, but lso from other ministries such s Justice, Internl Affirs, Eduction nd others. Such commitments re in the process of being trnsferred to regionl nd locl levels. The prtnership plys n essentil role in mintining politicl commitment when leders chnge nd when helth services re decentrlized. Finlly, the politicl commitment gined in Peru cn be seen in ntionl budget priorities. In the pst 15 yers, the verge budget llocted to the Ntionl TB Control Progrm ws US$ 3 million per yer. In 2006, this ws rised to lmost US$ 10 million, representing substntil politicl commitment. 5 O 1. Helth, key to prosperity: successful stories in developing countries.

9 Round tble discussion terntionl technicl ssistnce nd the Globl Drug Fcility s provision of qulity nti-tb drugs. Lbortory dignosis hs been mjor chllenge in the initil phse of DOTS expnsion. With interntionl technicl ssistnce nd vilbility of dditionl humn nd finncil resources, the microscopy network hs been substntilly strengthened. In 2005, 3530 new sputum smer-positive ptients were notified, which represents 26% increse over During the 1990s nd in line with heth sector reform, verticl progrmmes were bolished or scled down considerbly. Mli hs experienced wht uthors refer to s competing fshions. Implementtion of ntionl TB control guidelines, supervision, monitoring nd evlution were hmpered by competing priorities. To ddress these chllenges, the helth ministry recruited more stff t the centrl level nd identified regionl supervisors. Strengthened monitoring nd evlution led to significnt improvement of tretment outcome in most regions. The tretment success rte for new sputum smer-positive ptients improved from 61% for 2002 cohort to 77% for mid-2005 cohort, while the defult rte significntly decresed from 29% in 2002 to 7% in mid With further decentrliztion of tretment, improved supervision nd ptients eduction, higher tretment success rtes my be chievble. Mli is still fr from the globl trget of 70% TB cse detection of sputum smer-positive pulmonry ptients. Focus group discussions with ptients hve shown tht trditionl helers ply n importnt role in the Mlin society. Preliminry results of opertionl reserch in the Siksso region hve shown tht trining nd sustinble collbortion with trditionl helers my improve TB cse detection. 5 The level of drug resistnce is not known, but it is not expected to be high mong new ptients, s the tretment filure rte mong new TB ptients is only 2%. The progrmme considers direct observtion of tretment cornerstone of its strtegy to minimize the risk of drug-resistnt TB cses emerging. A limited study in Bmko hs shown tht 10.1% of TB ptients re co-infected with HIV. There is need to intensify TB/HIV collbortive ctivities, to offer HIV testing nd counselling for TB ptients nd to ddress bottlenecks in dignosis nd mngement of TB/HIV co-infection. Despite significnt progress due to the DOTS expnsion in Mli, chllenges remin tht require strong ntionl nd interntionl prtnerships to chieve sustinble TB control. O 1. World development indictors.
