However, during spring 2020, Japan employed a RT‐PCR test policy by using a guideline, which was used for the public to visit hospitals or clinics when they had mild symptoms for 4 days or longer (“4‐day rule”) among low‐risk patients. It is unknown of patients’ experience of healthcare use and testing during the period under the guideline. Thus, we investigated the healthcare visiting and testing among patients who developed cold‐like symptoms during the period. METHODS: Our survey was conducted online in September 2020 to a nationally representative sample of adults throughout Japan. We investigated the public's understanding of the guideline. In addition, we asked their experience with healthcare use and testing if they had noticed new‐onset cold‐like symptoms. RESULTS: Of 2,137 people surveyed, 1,698 (79.5%) recognized the guidelines, but 422 people (19.7%) misunderstood. There were 144 (6.7% of 2,137 people) who developed cold‐like symptoms, and many of them experienced difficulties in getting through telephone calls to a public health center, and 25 (17% of 144 people) visited healthcare institutions. Of these 25 symptomatic patients, 15 (60%) could not receive testing because of decisions by physicians (14 patients) or a local public health center (1 patient). CONCLUSION: There was a low use of healthcare and testing among symptomatic patients during the first wave of the pandemic in Japan. Testing capacity should be increased to provide effective care for patients with suspected COVID‐19 in Japan. have promptly announced "guideline" for the public on 17th February. 5 Table 1 shows the contents of the guideline. 5 If patients would visit hospitals or clinics and they might be indicated for coronavirus reverse transcription-polymerase chain reaction (RT-PCR) test based on the decision by physicians, physicians needed to call local public health centers if their patients could undergo coronavirus RT-PCR test. Because of the guideline, anecdotal reports indicated that there were many patients with upper respiratory symptoms who could not visit healthcare institutions and could not receive RT-PCR test. 6 The government of Japan declared a state of emergency on 7th April, and MHLW has revised the guideline on 8th May. However, over the pandemic period, the number of testing per unit population has not grown enough compared to that of other developed countries despite the high positivity in Japan. 7, 8 As community transmissions have grown in winter 2020-2021 throughout Japan, Japan has recorded the highest weekly number of patients in western pacific countries with highest number of deaths among these countries. 5 Despite this fact, the number of viral testing conducted in healthcare institutions is still low, 7, 8 which may reflect legacy effects from the previous guideline. Lessons learned from any governmental policies and responses and experience among the public and healthcare institutions are invaluable for the future pandemic management. 9 However, there has been no formal investigation about patients' experience and journey of healthcare use and testing during the period under the guideline. 10 Therefore, we conducted a Web-based questionnaire survey to investigate public understanding of the guideline and experience with healthcare use and testing during the period of the first wave of COVID-19. A Web-based questionnaire was developed and used to collect responses anonymously on September 10, 2020. When participants first visited the website for the survey, the policy for using the collected data and protection of personal information was displayed. Only those who agreed with the informed consent policy could participate in the questionnaire. This study was approved by the Ethics Committee. Our nationwide cross-sectional survey was designed and conducted online in September 2020 using a nationally representative sample of adults. From a nationwide public panel of 7.6 million people registered with the INTAGE Corporation, a research company, the survey participants were selected from Japanese adults aged 20-84 years and those who responded to the survey advertisement were contacted by the corporation. 11 Healthcare professionals or social workers were excluded because of the potential bias for responding differently from the public. Additionally, the participants were selected to reflect the distribution of the population (national population census of Japan in 2015) with regard to sex and age. Our study sample size was set at 2,000 based on that of the previous study with the similar methodology. 5 Percentages of sex, age, marriage, employment, and risk factors including hypertension, diabetes, chronic obstructive pulmonary disease, chronic renal failure on hemodialysis, immunocompromised diseases, or on immune suppressants, and prefecture were compared between the participants and the national population census using chi-square test statistics. Prefecture size was defined into 3 parts; a large size prefecture means a prefecture with a population of 5,00,000 or more, a middle size prefecture means a prefecture with a population between 2,00,000 and 5,00,000, and a small size prefecture means a prefecture with a population of 2,00,000 or less. We collected data on sex, age, chronic illness, family structure, and employment status. The questionnaire was developed following a consensus among the investigators based on the public opinion. 12 Each question sought to elicit public understanding and experience concerning healthcare use. Table 2 lists items of all questionnaires along with choices, and the items are classified into 4 parts. First, the survey asked respondents how much they understood the guideline (Q1). The second section of the survey asked them if they did not consider having a novel coronavirus infection when their symptoms did not match the "guideline" (Q2). In the third part, participants were asked their health condition (Q3) and behavior between February and May 2020, specifically cold-like symptoms (Q4-9). The last part dealt with telephone consultation and experience of healthcare use (Q10). For each of the questions, responses answered yes, no, or others (i.e., no idea for statements, refuse to answer) ( Table 2) . We also assessed variation in answers by respondent characteristics, such as age and sex. Intergroup differences in statistical data were assessed using chi-square tests for categorical variables, respectively. Descriptive statistics and percentages for proportions were used for the analyses. Guideline of the central government of Japan and societies of infectious diseases for the public, local public health centers, and healthcare institutions (4-day rule) Timing for patients' healthcare use and RT-PCR testing 1. Cold-like symptoms or fever of 37.5°C or over for four days or longer 2. Two days of the similar symptoms for the elderly or persons with risk factors a 3. Severe fatigue or dyspnea a Risk factors include hypertension, diabetes, chronic obstructive pulmonary disease, chronic renal failure on hemodialysis, immunocompromised diseases, or on immune suppressants. A total of 2,137 participants completed the survey over a 3-day recruitment period in September 2020. Table 3 summarizes the sociodemographic characteristics of the participants; sex and all age groups in this survey well represent the 2015 national census. 13 The proportion of employed people was lower among the participants compared to the general population (study participants 35.8% vs. total 57.5%) and that of persons who lived in small-sized prefectures was lower among the participants compared to the general population (study participants 22.1% vs. total 29.7%) ( Table 3) . An overview of the presence of symptoms among participants between February and May 2020, and experience after symptom onset is shown in Figure 1 . A total of 6.7% participants (144/2,137) experienced cold-like symptoms such as fever or cough from mid-February to May 2020. Among participants with these symptoms, Details of phone contacts to local public health centers are shown in Early diagnosis of patients with suspected COVID-19 has a significant impact on the clinical course and spread of the disease and prompt testing along with tracing and isolation has been recommended by most scientific communities and public health organizations. 14 Policies to enhance early visit and testing for all symptomatic persons in the early stages of the epidemic play an important role in its containment. 14 However, our study revealed the fact that only The telephone lines of many local public health centers were busy during COVID-19 pandemic so that most people with symptoms had to contact the health centers repeatedly. 15 Local public health centers are government facilities responsible for public health in Japan and are operating under the MHLW to engage in a variety of tasks. 15 Before COVID-19 pandemic, local public health centers had already been overwhelmed with many works such as health screening, health promotion, environmental sanitation, and recording and analyses about statistics on community health. 16 During the COVID-19 pandemic, the reliance on an inefficient paper-based system for reporting patient information in local public health centers had also caused inaccurate and duplicate records. 16 Thus, it is necessary to improve their operations to reduce their tasks. This study had several limitations. First, it was an online survey and did not employ face-to-face interviews with survey experts. It is also a self-reported assessment, which may overestimate its implementation because of social desirability bias, and the data may not a Definition of prefecture size. A prefecture with a population of 5,00,000 or more was considered as a large size prefecture, a prefecture with a population between 2,00,000 and 5,00,000 was considered as a middle size prefecture, and a prefecture with a population of 2,00,000 or less was considered as a small prefecture. b Distribution of characteristics between the two groups except underlying disease: Chi-square tests were conducted for sex (p = 0.999), age (p = 0.998), marriage (p = 0.001), employment (p = 0.007), and prefecture (p = 0.030). c As of National Census of Japan 2015. be accurate because of recall bias. 17 19 On the other hand, a state of emergency was declared in April 2020 in Japan, with reliance on citizens' selfrestraint and lack of law enforcement. 9 In addition, the capacity of RT-PCR testing was remarkably small; only 6,827 of RT-PCR testing were available daily in May 2020 in Japan, compared with 13,593 cases in December 2020. 20 In the early phase of the strategy against COVID-19 in Japan, testing capacity was limited and the 4-day rule guideline was implemented. However, sustainable and feasible long-term control of COVID-19 requires continuous review and improvement of the challenges to enable people and societies to keep activity them in their daily lives. In conclusion, this is the first study to investigate the public's knowledge of the COVID-19 guideline and patients' experience during the first wave in Japan. Since early testing is important for timely diagnosis and treatment along with contact tracing, testing capacity should be increased to provide effective care for patients with suspected COVID-19 in Japan.
