% Detailed pathway steps
\begin{tcolorbox}[colback=highlightgray!30,colframe=headerblue,title=\textbf{Detailed Pathway Steps},fonttitle=\bfseries]

\textbf{STEP 1: Initial Assessment}
\begin{itemize}
\item Vital signs: BP, HR, RR, temp, O₂ saturation
\item Focused history: [Key elements]
\item Physical examination: [Key findings]
\item Initial labs: [Specify tests]
\item ECG (if applicable)
\end{itemize}

\textbf{STEP 2: Risk Stratification}
\begin{itemize}
\item Calculate [Risk Score Name] (see scoring table below)
\item Identify high-risk features requiring immediate intervention
\item Document risk category in medical record
\end{itemize}

\textbf{STEP 3: Treatment Initiation}
\begin{itemize}
\item Urgent: [Specific interventions within 1 hour]
\item Semi-urgent: [Interventions within 24 hours]
\item Routine: [Standard management approach]
\end{itemize}

\textbf{STEP 4: Monitoring and Reassessment}
\begin{itemize}
\item Frequency: [Based on risk category]
\item Parameters: [What to monitor]
\item Escalation criteria: [When to intensify treatment]
\item De-escalation criteria: [When to transition to lower intensity]
\end{itemize}
