The impact of the COVID-19 pandemic on calls to a national suicide prevention hotline in Taiwan: An analysis of time trend and characteristics of calls

We investigated the impact of the COVID-19 pandemic on call volumes and call characteristics using data from a national crisis helpline. Data were extracted for 215,066 calls to Taiwan’s national suicide prevention hotline (January 2018–May 2020). We used negative binomial regression to investigate changes in the weekly number of calls during the early period of the COVID-19 outbreak (January 21, 2020–May 25, 2020), relative to that expected according to the pre-pandemic trend. The call characteristics during the pandemic period (February 18, 2020–May 31, 2020) were compared between COVID-19 related vs unrelated calls. Higher-than-expected call volumes started from the 6th week of the pandemic and reached a peak in the 14th week, which was 38% (rate ratio = 1.38, 95% confidence interval 1.26–1.51) higher than that expected based on the pre-pandemic trend. The higher-than-expected call volumes were mainly attributable to higher-than-expected calls from non-suicidal and male callers. Calls in which COVID-19 was mentioned (13.2%) were more likely to be from male and first-time callers, occur outside 12 am–6 am, last less than 5 min, and were less likely to be from callers who had previous suicide attempts, recent suicidal ideation or suicide plans or actions than COVID-19 unrelated calls. Callers who made COVID-19 related calls were more likely to request information than other callers. Crisis helplines should strategically adapt to the increased need and callers’ specific concerns related to the outbreak.
