'Preventable lapse' by service provider caused 9.5-hour public healthcare IT outage on Oct 13

Senior Minister of State for Health Tan Kiat How apologised for the Oct 13 disruption, saying it "should not have happened". The outage forced about 4,000 outpatient appointments to be rescheduled.

SINGAPORE: A "preventable" lapse by a contracted service provider to complete a required security update led to the nine-and-a-half hour disruption to services across Singapore's public healthcare clusters on Oct 13, Senior Minister of State for Health Tan Kiat How told parliament on Tuesday (Nov 3).

About 4,000 outpatient appointments were rescheduled, and some patients experienced delays of up to two hours, Mr Tan said. No adverse patient-safety incidents attributable to the disruption were reported.

The disruption impacted services across all three public healthcare clusters - NHG Health, the National University Health System (NUHS) and SingHealth.

Services affected included appointment bookings, visitor registration, medication dispensing and billing.

National health technology agency Synapxe had contracted a service provider to manage the necessary update, but it was not carried out, Mr Tan said. "Synapxe is reviewing the provider's contractual obligations and will take appropriate action for any established lapses. "Regardless of the outsourcing arrangement, Synapxe remains accountable for the resilience of its critical systems," Mr Tan said. The public healthcare systems have backup infrastructure, including two data centres. But both depended on the same underlying DNS service and security configuration, Mr Tan said. "Switching between them would therefore not have resolved this disruption. Synapxe will review such shared dependencies and strengthen alternative recovery arrangements." The required security update to a shared Domain Name System, or DNS was not completed before a scheduled global change, Mr Tan said, likening the DNS to an internet address book that helps systems locate and connect to applications. "This was a known change and a preventable lapse," Mr Tan said. The disruption on Oct 13 caused inconvenience and concern to patients and their families, and created additional work for healthcare workers, said Mr Tan. "We apologise. It should not have happened." The investigation found that this was not a cyberattack, and there was no unauthorised access to, compromise or loss of patient data, he added. Noting the duration of the disruption, Mr Tan added that monitoring detected abnormal activity, but it took time to identify the underlying problem and restore services safely. Synapxe is strengthening monitoring and fault diagnosis to enable faster recovery, Mr Tan said. EXPERT PANEL Mr Tan said the government is strengthening resilience in three areas: prevention, by improving the tracking and verification of critical technical changes; and containment, by addressing shared dependencies and improving recovery arrangements. The third area involves continuity of care, by improving downtime systems, staff readiness and regular exercises, including for partial outages "MOH will oversee the corrective actions and verify that they are effective," he said. Synapxe has appointed an expert panel comprising representatives from other organisations that have similar engineering profiles to review the investigation findings and proposed remediation measures and identify further improvements. "Digitalisation brings important benefits to healthcare. But as our systems become more interconnected, resilience must improve too. "We must make our technology more reliable, while ensuring healthcare workers can continue caring for patients safely even when technology fails," said Mr Tan.

Healthcare institutions activated downtime procedures, with additional staff supporting operations and clinicians using selected read-only patient records and manual workflows to continue essential care, Mr Tan said.

卫生部高级政务部长陈杰豪就10月13日的网络中断事件道歉，称“本不应该发生”。此次中断导致约4000个门诊预约被迫重新安排。

新加坡：卫生部高级政务部长陈杰豪周二（11月3日）在国会表示，10月13日，由于承包服务提供商未能完成必要的安全更新，导致新加坡公共医疗保健集群的服务中断了9个半小时，而这本是可以避免的。

谭先生表示，约有4000个门诊预约被重新安排，部分患者就诊延误长达两小时。未报告任何因此次延误导致的患者安全事故。

此次中断影响了所有三个公共医疗保健集群的服务——NHG Health、新加坡国立大学医疗系统 (NUHS) 和新加坡保健集团 (SingHealth)。

受影响的服务包括预约、访客登记、药品配发和账单结算。

CNA游戏 猜词游戏 逐行破解单词 流行词游戏 用给定的字母组成单词 迷你数独 小谜题，脑力挑战 迷你填字游戏 小方格，大挑战 单词搜索 尽可能多地找出单词 显示更多 显示更少 谭先生表示，医疗机构已启动停机应急预案，增派人手支援运营，临床医生使用选定的只读患者记录和手动工作流程来继续提供必要的护理。谭先生说，国家卫生技术机构Synapxe已与一家服务提供商签订合同，负责管理必要的更新，但更新并未执行。“Synapxe正在审查该提供商的合同义务，并将对任何已发现的违约行为采取适当措施。”谭先生说，“无论外包安排如何，Synapxe仍对其关键系统的弹性负责。” 公共医疗系统拥有备份基础设施，包括两个数据中心。但谭先生说，这两个数据中心都依赖于相同的底层DNS服务和安全配置。“因此，在它们之间切换并不能解决此次中断问题。” Synapxe将审查此类共享依赖关系，并加强替代恢复方案。” Tan先生表示，共享域名系统（DNS）所需的安全更新在计划的全局变更之前未能完成。他将DNS比作互联网地址簿，帮助系统定位并连接到应用程序。“这是一个已知的变更，也是一个可以避免的疏忽，” Tan先生说。Tan先生表示，10月13日的故障给患者及其家属带来了不便和担忧，也给医护人员增加了额外的工作量。“我们深表歉意。” “这本不应该发生。”他补充说，调查发现这不是网络攻击，也没有未经授权访问、泄露或丢失患者数据的情况。谭先生指出，虽然监控检测到了异常活动，但识别根本问题并安全恢复服务需要时间。谭先生表示，Synapxe正在加强监控和故障诊断，以实现更快的恢复。专家小组 谭先生表示，政府正在三个方面加强韧性：预防，通过改进对关键技术变更的跟踪和验证；遏制，通过解决共享依赖关系和改进恢复安排；第三个方面是护理的连续性，通过改进停机系统、员工准备情况和定期演练（包括部分停机演练）。“卫生部将监督纠正措施并验证其有效性，”他说。Synapxe已任命一个专家小组，成员来自其他具有类似工程背景的机构，负责审查调查结果和拟议的补救措施，并确定进一步的改进措施。“数字化为医疗保健带来了重要益处。但随着我们的系统变得越来越互联，韧性也必须提高。” “我们必须提高技术的可靠性，同时确保即使在技术出现故障时，医护人员也能继续安全地照顾病人，”谭先生说。

谭先生表示，医疗机构已启动停机程序，增派人员支持运营，临床医生使用选定的只读病人记录和手动工作流程来继续提供必要的护理。

谭先生表示，国家卫生技术机构 Synapxe 已与服务提供商签订合同，负责进行必要的更新，但更新并未执行。

Synapxe正在审查供应商的合同义务，并将对任何已确定的违约行为采取适当的行动。

“无论外包安排如何，Synapxe 仍需对其关键系统的韧性负责，”谭先生说。

谭先生表示，公共医疗系统拥有备用基础设施，包括两个数据中心。但这两个数据中心都依赖于相同的底层DNS服务和安全配置。

“因此，在它们之间切换并不能解决此次故障。Synapxe 将审查此类共享依赖关系，并加强替代恢复机制。”

Tan 先生表示，共享域名系统 (DNS) 所需的安全更新在计划的全局更改之前尚未完成。他将 DNS 比作互联网地址簿，帮助系统定位和连接到应用程序。

“这是一个已知的变化，也是一个可以避免的疏忽，”谭先生说。

谭先生表示，10 月 13 日的中断给患者及其家属带来了不便和担忧，也给医护人员增加了额外的工作量。

“我们深表歉意。这本不应该发生。”

他补充说，调查发现这不是网络攻击，也没有发生未经授权访问、泄露或丢失患者数据的情况。

谭先生指出中断持续时间较长，并补充说，监测发现了异常活动，但需要时间才能确定根本问题并安全地恢复服务。

谭先生表示，Synapxe正在加强监控和故障诊断，以实现更快的恢复。

陈先生表示，政府正在三个方面加强韧性：预防，通过改进对关键技术变化的跟踪和核实；遏制，通过解决共同依赖关系和改进恢复安排。

第三个方面涉及护理的连续性，通过改进停机维护系统、提高员工准备水平和开展定期演练（包括针对部分停机情况的演练）来实现。

他说：“卫生部将监督整改措施，并核实其有效性。”

Synapxe 已任命一个专家小组，该小组由其他具有类似工程背景的组织的代表组成，负责审查调查结果和提出的补救措施，并确定进一步的改进措施。

数字化为医疗保健带来了诸多益处。但随着我们的系统日益互联互通，其韧性也必须得到提升。

“我们必须提高技术的可靠性，同时确保即使在技术出现故障时，医护人员也能继续安全地照顾病人，”谭先生说。
