"Implementing an Integrated Management System in Outpatient Healthcare Productivity Outcomes of ISO 90012015, ISO 450012018, and ISO 140012015"

Resumen

"This study assesses how an Integrated Management System (IMS) aligned with ISO 9001:2015 (quality), ISO 45001:2018 (occupational health and safety), and ISO 14001:2015 (environment) affects productivity in an outpatient healthcare setting. An 18-month, phased implementation consolidated governance, risk, and process control into a single architecture, replacing parallel programs with shared policies, integrated audits, and unified corrective-action workflows. Using a mixed-methods, pre–post design, we tracked key performance indicators—patient lead time, throughput per clinician hour, appointment punctuality, first-contact resolution, rework, incident and near-miss rates, absenteeism, energy and water intensity per visit, waste segregation, and cost-to-serve—while capturing staff and patient perceptions through surveys and focus groups. Interrupted time- series analyses revealed sustained improvements in operational flow and sched- ule adherence, reductions in clinical and occupational incidents, and lower re- source intensity per encounter. Financial analysis indicated cost avoidance and margin uplift associated with standardized work, clearer role accountability, and risk-based maintenance. Qualitative evidence highlighted a stronger safety culture, greater cross-functional problem solving, and higher employee engagement. Overall, implementing a tri-standard IMS as one coherent system—not three separate ones—delivered measurable gains in productivity, safety, and environmental performance, strengthening organizational resilience and regulatory compliance. The paper contributes a practical roadmap for outpatient providers, including a staged roll-out plan, a core KPI set for integrated oversight, and an audit cadence that links nonconformities to continuous-improvement projects with demonstrable operational impact. © The Author(s), under exclusive license to Springer Nature Switzerland AG 2026."
