29 July, 2010 Adapting Standard Clinical Guidelines to the Context of HIV-Related Patient Care in Resource- Constrained Settings Ian Crozier, MD and Paula Brentlinger, MD
First, thanks to ourcollaboratorsand funders! Collaborators: Mozambique (I-TECH, Ministry of Health, CDC, others): Paul Thottingal, Mark Micek, Oliver Bacon, José Vallejo, Rui Bastos, Rolanda Manuel, Pilar Martínez, Florindo Mudender, Maria Ruano, Monica Negrete, and others! Uganda (IDCAP, IDI, Accordia, I-TECH, Uganda MOH): Ann Miceli, Marcia Weaver, Allan Ronald, Mike Scheld, Lydia Mpanga Sebuyira, Kelly Willis.

A simple (?) case • Imagine that you are a mid-level clinician in sub-Saharan Africa,seeing an HIV+ adult patient whose hemoglobin level is 7.7 g/dL. • What should you do first to address this patient’s anemia? • Why? TYPE YOUR ANSWERS NOW!
Simple (?) case 2 • Now, imagine that you are a mid-level clinician in sub-Saharan Africaseeing an HIV+ adult patient whose axillary temperature is 38.5° C. • What should you do first to address this patient’s fever? • Why? TYPE YOUR ANSWERS NOW!

Mozambique, 2005-6: DuelingGuidelines, Anemia • Check for “generaldangersigns”. • If a patientseemspale, giveferrous sulfate, mebendazole, and1stline antimalarials (nolaboratorytestingneeded). Ifextremelypale, refer. • Iftheanemicpatientison zidovudine, gradethe adverse drugreactionandtreataccordingly. • Ifthepatientwithseveremalariahas a hemoglobin <5 g/dL, transfuse.
Mozambique, 2005-6: DuelingGuidelines, Fever • Check for “general danger signs”. • Give antimalarials (no lab tests required); add antibiotics if very sick. • Lumbar puncture; send for gram stain, AFB, india ink, VDRL • Consider adverse drug reaction to antiretrovirals; grade and treat accordingly • If severe malaria, give quinine; if uncomplicated malaria, give 1st line
What to do? Options: • Pickoneofthemanycompetingguidelinesand stick toit? • Adoptexistingguidelinesfromothercountries/sources? • Writenewguidelines?
CharacteristicsofnewMozambicanguidelines Topics: Commonsignsorsymptoms (patient-based, notdisease-based) Patientevaluation: Directed, basedonhistory, physicalexamination, and use ofavailabletests (malaria, HIV, AFB, hemoglobin) Differentialdiagnosis: Emphasizecommonillnessesthatcanbediagnosedandtreatedwithavailableresourceswithinapprovedscopeofpracticeoftargetcadre (more complexproblems to bereferredupward) Layout: 1 page, easy to read, parallelorganization for differentguidelines General: evidencebased, consistentwith major local (TB, malaria, AIDS, antenatalcareprograms) andinternationalguidelines (IMAIetc) wheneverpossible, harmonize disease-specificguidelineswheneverpossible
Integrationofnewguidelinesand curricula Modules/sessionsinbothin-serviceandpre-service curricula corresponded to guidelinetopics (e.g. “diarrhea”, “weightloss”, “coughor dyspnea”). Evidencesupportingguidelinedevelopment (epidemiologic, health-outcomes) summarizedin curricula. Stepwisepresentationofguidelines. In-class case studies to besolvedusingguidelines; generally, >=1 casepresentation per guidelinearm. Writing cases helpedus spot guidelineflaws, anddroverevisions!
Sample case-study questions • Whichguidelineorguidelinesshouldyou use toaddressthis case, andwhy? • Does thispatienthavedangersigns, orcanyouproceed to thenextstepsoftheguideline? • Whichpathwayshouldyoutakenext (e.g. Box xor Box y), andwhy? • Canyoumanagethispatientwiththeguideline, or do youneed to refer?
Use ofguidelinesinpracticumsessions Similarly, in practicum sessions (or post-course mentoring/supervision): Trainees practice using guidelines to manage real patients. Faculty/supervisors use guidelines as standard for evaluation of trainee performance
Shift context Uganda IDCAP RCT studying the most cost-effective way to build capacity for the care and prevention of infectious diseases among mid-level providers in Uganda
Context: the training design Classroom On-site
Context: the curriculum goal Develop training materials that: • INTEGRATE infectious diseases training (with emphasis on HIV/TB/malaria and common others) • use a CASE-BASED approach to frame key content • TARGET mid-level providers at the health center IV level in Uganda
A 35 yo woman with fever: After triaging (no danger signs), a careful history and physical examination reveals no localizing signs or symptoms to suggest an obvious cause of fever. The malaria smear is negative. What should you do?
Should you: • Give an antimalarial? • Give an antibiotic? • Give symptomatic treatment with f/up only? • Stop or start any other medicines? • Refer for further testing or care? What criteria impact these decisions? Does it make a difference if the patient is HIV-infected or not? Using cotrimoxazole? Pregnant? On TB treatment?
An HIV-infected mother gives birth to a healthy child in Uganda… • What routine important evaluation, prevention, and care should occur immediately? • What routine important evaluation, prevention, and care should occur over the next 12-18 months?
The hunter in pursuit of an elephant does not stop to throw stones at birds…….
Similar issues in Uganda: • “Dueling” clinical guidelines (HIV/TB/Malaria), • Guidelines often either • Impractical for MLPs at the HC IV level (i.e. incorporate unavailable laboratory testing, etc), or • Leave no “room” for MLP skill in clinical evaluation, reasoning, and decision-making • In some clinical scenarios, no clear guidelines
Focus on the important clinical decisions… • Prescriptive (when possible) • Practical tool for day-to day clinical use and consultation • Effective for classroom and on-site clinical mentoring
Clinical Decision-Making Guide(s) Anatomy • Introduction: rationale and how-to-use • Clinical decision-making guides (CDG): clinical algorithmsplus explanatory notes • Appendix tools: useful existing clinical reference material(s)
Types of decision-making • Evaluation and management of new signs/symptoms (“unknowns”) • Routine case management in HIV, TB, malaria
Section: routine case mgt Emphasizing: • Correct case-definitions and classification • Correct pre-treatment evaluation/preparation • Correct identification of those who require consultation/referral prior to initiation of Rx • Correct selection/dosing of specific and supportive Rx • Correct monitoring for AE and treatment effectiveness
Development of the CDGs Guides constructed around important clinical decision-making • Identifying the important clinical decisions that may need to be made in a patient with _________. • Identifying the information needed to make these decisions? (this informs and focuses the clinical evaluation). • Identifying and outlining the criteria by which key decisions are made? • Representing this process in a graphical format (with explanatory notes AND referencing appendix tables)
Principles of the CDGs (Uganda) • RECOMMENDATIONS for decision-making in particular clinical scenarios • Sourced from national guidelines whenever possible (then relevant local/regional scientific literature, int’l GL, expert opinion) • Designed to integrate decision-making in multiple populations when possible • Supplement to the core training material but real “rollout” in distance learning and booster sessions

Mozambique Uganda: key differences • Context: designed for use in RCT of 2 different approaches to MLP training in UG. • Target pop’n: address HIV+ and HIV- adults and children • Layout: extensive footnoting and appendix references • (?) link to trainee performance evaluation....
Measuring trainee performance • As part of the study, PB was tasked with design and creation of a set of “case scenarios” to accurately assess and capture trainee performance in clinical evaluation, reasoning, and management. • Forced identification of the key “testable” skills LINKED to core training material • This process was one of the prime drivers of the development and adaptation of the IDCAP guides…
Gaps and challenges (1) Related to nationalorinternationalpolicy: 1. Theduelingalgorithmproblem does notoriginatelocally – some guidelinesoriginateinGenevaortheUSorEuropeanheadquartersoflocally active aid agencies. 2. Constantevolutionofscopeofworkofnon-physicianclinicians (canthey do lumbarpunctures? Cantheyprescribe2ndline antiretrovirals or TB drugs?). RequirednationalconsensusconferenceinMozambique. Related to thescientificevidence base: 1. Constantevolutionofpublishedevidence base drivesfrequentrevisionsofinternational (WHO, PEPFAR, etc) standards. 2. Still, manylacunaeinevidence base (Which antimalarials canbegivensafelyandeffectively to patientsonART + TBtreatment? Is visceral leishmaniasisanimportantcontributor to anemiainprovincex? )
Gaps and challenges (2) Related to thecomplexitiesofpatientcareinresource-constrainedsettings: 1. Some commonproblemshavenotbeenamenable to guidelinedevelopment (e.g. abdominal pain, overlapping adverse drugreactionsinpatientsonART + multipleotheragents) 2. Lackofresources (laboratory, imaging, surgeons, drugs) is a seriousconstraint to constructionofaneffectiveapproach to someclinicallyimportantproblems (e.g. alteredlevelofconsciousness) 3. Use ofguidelinesinpatientswithmultiple active comorbidities. Priorities for thefuture 1. Validationofnewguidelines (studiesabout to commenceinMozambique [VanderbiltUniversity]) 2. Workableplan for frequentrevision as evidence base and local/international policies evolve
More gaps/challenges (Uganda) • In an expanded target population, unique challenges in designing and integrating guides with current models that are variably implemented (especially under 5’s and IMCI) • Less “mature” in the development process: more adaptation/refining of guides required, preferably in growing partnerships (MOH, etc)
