HistoryofHealthcareSystems
Theconceptofahealthcaresystemhasevolvedsignificantlyovertime,reflectingthechangingneeds,values,andcapabilitiesofsocieties.Historically,healthcare
systemswererelativelyrudimentary,oftenrelyingoninformalnetworksofcarewithincommunitiesorreligiousinstitutions.However,asmedicalknowledgeadvancedandsocietiesbecamemorecomplex,sotoodidtheirhealthcaresystems.
Themodernhealthcaresystemcanbecharacterizedasastructuredcombinationofresources,organization,financing,andmanagementdesignedtoprovidehealthservicestothepopulation[6].Thissystemincludesabroadarrayofstakeholderssuchashealthproviders,consumers,healthfinancingagencies,resourcessuppliers,andgovernmental/regulatoryentities[6].

TheBeveridgeModel
TheBeveridgeModel,alsoknownas"socializedmedicine,"wasfirstintroducedbyBritisheconomistandsocialreformerWilliamBeveridgein1948.Thismodelaimstoprovidehealthcareforallcitizensandisfundedthroughtaxpayments[11].UndertheBeveridgeModel,mosthospitalsandclinicsareownedbythegovernment,andmanydoctorsandhealthcareprofessionalsaregovernmentemployees.However,privateinstitutionsalsoexistandcollectfeesfromthegovernment[12].ThismodelisprimarilyusedinGreatBritain,Spain,andNewZealand[12].Oneofthekey
advantagesofthissystemisthathealthservicesarefreeatthepointofuse,makingthemaccessibletoeverycitizen[13].However,itoftenfaceschallengessuchaslongwaitinglistsfortreatment[13].

HealthcareSystemsbyCountry
BismarckModel
TheBismarckModel,alsoknownastheSocialHealthInsuranceModel,ischaracter-
izedbythefundingofhealthcarethroughcontributionstoahealthfund,whichpays
forhealthservicesprovidedbyeitherstate-owned,government-owned,orprivate
institutions.IntroducedbyOttovonBismarckinGermanyin1883,thismodelinitially
aimedtoprovidecaretoworkersandtheirfamilies[15][16].CountriessuchasGer-
many,Austria,Switzerland,andtheCzechRepublicoperateunderthissystem[16].
TheprimaryadvantagesoftheBismarckModelincludesignificantlyhigheracces-
sibility,lowerwaitingtimes,andoftenhigherqualityandmoreconsumer-oriented
healthcare,attributedtothecompetitionbetweenhealthcareproviders[15][16].
However,theBismarckModelfacescriticismregardingtheprovisionofcarefor
individualsunabletoworkoraffordcontributions,suchasagingpopulationsand
theimbalancebetweenretireesandemployees[15].Toaddressthis,manyBismarck
systemshaveevolvedtoprovidestateinsuranceorcontributionstothoseunableto
pay,aimingtoensureuniversalcoverage[16].
BeveridgeModel
TheBeveridgeModel,createdbyeconomistandsocialreformerWiliamBeveridge,wasfirstimplementedintheUnitedKingdomwiththeestablishmentoftheNationalHealthService(NHS)in1948[14][11].Thismodelisbuiltontheprincipleofhealth-careasahumanright,withfundingprimarilythroughtaxation.CountriesemployingvariationsoftheBeveridgeModelincludetheUnitedKingdom,Italy,Spain,Denmark,Sweden,Norway,NewZealand,andothers[14[11].Underthismodel,healthcareservicesaregenerallyfreeatthepointofuse,withthecostcoveredbythepatientstaxcontributions[11].
TheBeveridgeModelemphasizesuniversalcoverageprovidedbythegovernment,ensuringthatallresidentshaveaccesstohealthcare[11].IntheUnitedStates,
aspectsofthismodelareappliedtoveteransandNativeAmericans[14].
ComparisonandChallenges
Nocountryhasaperfecthealthcaresystem,andinadequatehealthcareremainsaglobalissue[15].Healthsystemsareheavilyinfluencedbythenormsandvaluesoftheirrespectivesocietiesandreflectdeeplyrootedsocialandculturalexpectations[15].TheWorldHealthOrganization(WHO)identifiesthegoalsofhealthcaresystemsasensuringgoodhealthforcitizens,responsivenesstothepopulation'sexpectations,andfairfundingmechanisms[17].

GlobalPerspective
Globally,healthcaresystemsrangefromhighlyregulatedstructurestolocal,
shaman-dependentsetups,demonstratingthediversityinapproachestohealthcareprovision[14].Despitethisdiversity,lessonsfromtop-performingcountriescanin-formimprovementsinhealthcaresystemsworldwide[5].Forexample,single-payersystems,whereasingleentitycollectsandpaysforhealthcareservices,aremorecommonamongwealthynationsandareoftencontrastedwithmulti-payersystems,suchasthatoftheUnitedStates[19].
Ultimately,recognizingthediversityofstakeholdersandthecomplexityofhealthsystemsiscrucialfordevelopingeffective,evidence-basedhealthcarepolicies[17].Qualityimprovementinitiativesarefrequentlyimplementedtobridgepolicygapsandenhancehealthcaredelivery[17].
GlobalHealthIssuesandChallenges
Universalaccesstohealthistheguidingprincipleandhealthequityamongnationsandforallpeopleisthemajorobjectiveofglobalhealth.Globalhealthinitiatives
wereestablishedtotackleincreasingglobalhealththreats,reducedisparitieswithincommunitiesandbetweennations,andcontributetoaworldwherepeoplelive
healthier,safer,andlongerlives.TheseinitiativesaddressvariousareasincludingAIDS,tuberculosis,malaria,immunizationprograms,maternalandchildhealth,
tobaccouse,humanresources,emergingdiseases,nutrition,healthpromotion,andhealthsystemstrengthening[20].
However,protractedsocialandpoliticalunrestinmanygrant-recipientcountries
remainsasignificantchallenge.Insecurityintheseregionshampersaccesstosocialservices,withthehealthsectorbeingtheworstaffected.Thelossofhumancapitalhasseverelyweakenedhealthservicesandsystemsinaffectedcountries.Addition-ally,globalhealthinitiativeshavesometimescreatedparallelsystemsthatunderminetheholisticapproachtohealthsystemdevelopment.Theprinciplesofexternalaid,suchasownershipandharmonization,arenotalwaysadequatelyapplied,furthercomplicatingtheeffectivenessoftheseinitiatives[20].

Whileglobaldeclarationsandcountrycommitments,suchasthosebytheUnitedNationsGeneralAssemblyonUniversalHealthCoverage(UHC),haveputUHCatthecenterofhealthpoliciesandstrategies,progressisunevenacrosscountries,
andsignificantgapsremain[23].Additionally,mosthealthexpendituresindevel-

HealthcareFinancing
Healthcarefinancingvariessignificantlyacrosstheglobe,influencedbyamixof
publicandprivatefundingsources,theroleofgovernment,andtheeconomicstatusofeachcountry.
Developingcountrieshaveseentheirhealthcarefinancingshapedlargelybyde-
velopmentassistance,particularlyfollowingtheintroductionoftheMillenniumDe-velopmentGoals,whichledtoasteepincreaseinresourceschanneledthrough
aid.Theseflowsaccountforabout0.7%ofthehealthcareresourcesspentby
high-incomecountries[9].Countrieswithlowpublichealthcarespendingandlimitedprivatevoluntaryinsurancetypicallyseehighout-of-pocketexpenditure(e.g.,India,Afghanistan,Sudan)[9].
Incontrast,inhigh-incomecountrieswithsubstantialpublicfundsorprivatevoluntaryinsurance,out-of-pocketspendingisrelativelylow.Thisfinancialstructuringaimstoprovide'prepaidcare'throughcompulsorysocialinsuranceorfundingfromgeneralgovernmentrevenue[9].Healthfinancingisacorefunctionthatcandriveprogresstowarduniversalhealthcoverage(UHC)byimprovingservicecoverageandfinancialprotection[18].
WHO'shealthfinancingteamcollaborateswithhealthministriesandfinanceauthor-itiestodevelopbetterbudgetingprocessesandalignpublicfinancialmanagementreformswithhealthfinancingsystems[26].Effectivehealthcarefinancingrequiresacomprehensivefinancialframework,whichcouldincludemechanismslikemonthlypremiumsorannualtaxestoensureadequatefundingforhealthcarebenefits[17].Countriesoftenrelyonamixoffundingsources.Forinstance,theGlobalFund'sgrantsareperformance-based,whichencouragesefficiencyandproductivityin
