      const guideline = clinicalGuidelines.find((g) => g.ruleId === rule.id);

      if (guideline) {
        // Customize rule based on local evidence
        const customizedRule = await this.applyLocalCustomizations(
          rule,
          guideline
        );
        customizedRules.push(customizedRule);
      }
    }

    return customizedRules;
  }

  private async applyLocalCustomizations(
    rule: CDSRule,
    guideline: ClinicalGuideline
  ): Promise<CustomizedCDSRule> {
    return {
      ...rule,
      localModifications: [

      approvalRequired: guideline.requiresApproval,
    };
  }
}

Phase 4: Testing and Validation

4.1 Integration Testing Strategy

Comprehensive Testing Framework:

class CPOEIntegrationTester {
  private testFramework: TestFramework;
  private dataValidator: DataValidator;
  private performanceTester: PerformanceTester;
  private securityTester: SecurityTester;

  async executeIntegrationTesting(
    integration: CPOEIntegration
  ): Promise<TestResults> {
    // Unit testing
    const unitTests = await this.executeUnitTests(integration);

    // Integration testing
    const integrationTests = await this.executeIntegrationTests(integration);

    // Performance testing
    const performanceTests = await this.executePerformanceTests(integration);

    // Security testing
    const securityTests = await this.executeSecurityTests(integration);

    return {
      unitTests,
      integrationTests,
      performanceTests,
      securityTests,
      overallStatus: this.calculateOverallStatus([
        unitTests,
        integrationTests,
        performanceTests,
        securityTests,
      ]),
    };
  }

  private async executeIntegrationTests(
    integration: CPOEIntegration
  ): Promise<IntegrationTestResults> {
    const testScenarios: IntegrationTestScenario[] = [
      {
        name: "patient_data_synchronization",
        description: "Test patient data sync between EHR and CPOE",
        steps: [
          "create_patient_in_ehr",
          "verify_patient_appears_in_cpoe",
          "update_patient_in_ehr",
          "verify_update_reflected_in_cpoe",
        ],
        expectedResults: [
          "patient_data_consistent",
          "synchronization_time_under_2_seconds",
          "no_data_loss",
        ],
      },
      {
        name: "medication_order_flow",
        description: "Test complete medication order workflow",
        steps: [
          "initiate_order_in_cpoe",
          "validate_order_against_ehr_data",
          "route_order_to_pharmacy",
          "track_order_status",
          "document_administration",
        ],
        expectedResults: [
          "order_validation_accurate",
          "pharmacy_routing_successful",
          "status_tracking_real_time",
          "documentation_automatic",
        ],
      },
    ];

    const results = await Promise.all(
      testScenarios.map((scenario) => this.executeTestScenario(scenario))
    );

    return {
      scenarios: results,
      passRate: this.calculatePassRate(results),
      averageExecutionTime: this.calculateAverageExecutionTime(results),
    };
  }
}

Phase 5: Deployment and Go-Live

5.1 Staged Rollout Strategy

Controlled Deployment Approach:

class CPOEDeploymentManager {
  private deploymentOrchestrator: DeploymentOrchestrator;
  private rollbackManager: RollbackManager;
  private monitoringService: MonitoringService;
  private supportTeam: SupportTeam;

  async executeStagedRollout(
    deploymentPlan: DeploymentPlan
  ): Promise<DeploymentResult> {
    // Phase 1: Pilot deployment
    const pilotResult = await this.deployToPilot(deploymentPlan.pilot);

    // Phase 2: Department rollout
    const departmentResults = await this.rolloutByDepartment(
      deploymentPlan.departments
    );

    // Phase 3: Organization-wide deployment
    const organizationResult = await this.deployOrganizationWide(
      deploymentPlan.organization
    );

    return {
      pilotResult,
      departmentResults,
      organizationResult,
      overallSuccess: this.assessOverallSuccess([
        pilotResult,
        ...departmentResults,
        organizationResult,
      ]),
    };
  }

  private async deployToPilot(
    pilotConfig: PilotConfiguration
  ): Promise<DeploymentPhaseResult> {
    // Deploy to limited user group for validation
    const deployment = await this.deploymentOrchestrator.deployToPilot(
      pilotConfig
    );

    // Monitor pilot performance
    const monitoring = await this.monitoringService.monitorPilot(deployment);

    // Gather feedback and make adjustments
    const feedback = await this.gatherPilotFeedback(deployment);

    return {
      phase: "pilot",
      status: monitoring.status,
      metrics: monitoring.metrics,
      feedback: feedback.summary,
      adjustments: feedback.requiredAdjustments,
    };
  }
}

Phase 6: Post-Implementation Optimization

6.1 Performance Monitoring and Optimization

Continuous Performance Management:

class CPOEPerformanceOptimizer {
  private metricsCollector: MetricsCollector;
  private performanceAnalyzer: PerformanceAnalyzer;
  private optimizationEngine: OptimizationEngine;
  private alertingService: AlertingService;

  async optimizeCPOEPerformance(
    integration: CPOEIntegration
  ): Promise<OptimizationResult> {
    // Collect performance metrics
    const metrics = await this.metricsCollector.collectMetrics(integration);

    // Analyze performance patterns
    const analysis = await this.performanceAnalyzer.analyzePerformance(metrics);

    // Identify optimization opportunities
    const opportunities = await this.identifyOptimizationOpportunities(
      analysis
    );

    // Implement optimizations
    const optimizations = await this.implementOptimizations(
      opportunities,
      integration
    );

    return {
      currentMetrics: metrics,
      analysis,
      opportunities,
      optimizations,
      projectedImprovements: await this.calculateProjectedImprovements(
        optimizations
      ),
    };
  }

  private async identifyOptimizationOpportunities(
    analysis: PerformanceAnalysis
  ): Promise<OptimizationOpportunity[]> {
    const opportunities: OptimizationOpportunity[] = [];

    // Response time optimization
    if (analysis.averageResponseTime > 2000) {
      opportunities.push({
        type: "response_time_optimization",
        priority: "high",
        description:
          "Reduce API response times through caching and optimization",
        potentialImprovement: "40% faster response times",
        implementationEffort: "medium",
      });
    }

    // Database query optimization
    if (analysis.databaseQueryTime > 500) {
      opportunities.push({
        type: "query_optimization",
        priority: "high",
        description: "Optimize database queries and implement proper indexing",
        potentialImprovement: "60% faster query performance",
        implementationEffort: "low",
      });
    }

    return opportunities;
  }
}
