Incidence rates of myocarditis and pericarditis within 30 days following homologous and heterologous BNT162b2 vaccinations in individuals 5-40 years of age.

INTRODUCTION: Due to the data scarcity in low- and middle-income countries, we aimed to examine the incidence rate of myocarditis and pericarditis within 30 days after each dose of homologous (3 × BNT162b2) and heterologous prime-boost (2 × BBIBP-CorV/BNT162b2) vaccine regimen among individuals younger than 40 years. METHODS: We conducted a historical control cohort using routinely recorded data from Thai national vaccine and insurance claims databases. Sex-specific incidence rate ratios (IRRs) for myocarditis and pericarditis were calculated for each vaccination strategy and contrasted with incidence rates among the non-immunised population in the pre-COVID-19 period. From August 2021 to September 2022, we tracked the incidence of myocarditis and pericarditis within 30 days after vaccinations using < 40-year-old national population databases. Our reference was the average monthly incidence of these conditions in the non-immunised population from August to October 2019. The exposure of interest was immunisation against the SARS-CoV-2 virus, incorporating the following vaccination strategies: three-dose 3 × BNT162b2 regimen, three-dose 2 × BBIBP-CorV/BNT162b2 regimen, and non-immunisation. RESULTS: For myocarditis, a total of 215 cases were identified among 7,594,965 individuals in the 3 × BNT162b2 cohort, 5 cases among 2,914,643 individuals in the 2 × BBIBP-CorV/BNT162b2 cohort, and 115 cases among 32,424,780 non-immunised individuals. The sex-specific IRRs (95 % confidence intervals) of myocarditis and pericarditis after the homologous vaccination were 3.09 (1.61, 5.93) and 1.84 (0.72, 4.73) for females and 7.43 (3.11, 17.73) and 10.48 (3.90, 28.15) for males, respectively. Conversely, the IRRs of myocarditis after the heterologous vaccination were not significant (females: 2.24 (0.70, 7.17); males: 1.99 (0.48, 8.21)). IRRs could not be obtained for pericarditis after the heterologous vaccination because of the small number of observed events. CONCLUSIONS: The study observed a significantly increased risk of myocarditis and pericarditis following homologous 3 × BNT162b2 vaccination but had insufficient power to confirm an increased risk for myocarditis following the heterologous prime-boost 2 × BBIBP-CorV/BNT162b2 vaccination. The incidence of pericarditis following the heterologous vaccination was too rare to evaluate.

Regulation of opioid drugs in thai government hospitals: Thailand national survey 2012.

CONTEXT: Palliative care in Thailand was not well developed in the past. Previous studies showed that the actual prescription of opioids was underutilized in palliative care by physicians compared with the estimated opioid need of patients. However, there were no studies regarding the regulation of opioids in Thailand. AIMS: To provide an up-to-date overview of the role of multidisciplinary teams in the regulation of opioids in Thai government hospitals. SETTINGS AND DESIGN: A questionnaire survey study was conducted from January to April 2012. MATERIALS AND METHODS: The questionnaire was distributed to entire population of government hospitals in Thailand and all private hospitals in Bangkok. There were 975 hospitals, including 93 private hospitals in Bangkok and 882 government hospitals. STATISTICAL ANALYSIS USED: Results are presented as a frequency and percentage. RESULTS: Special opioid prescription forms must be signed by doctors for all opioid prescriptions. Three-fourths of hospitals totally prohibited prescribing oral opioids by palliative care Advance Practice Nurses. Pharmacists were permitted to correct the technical errors on a prescription of oral morphine only after notifying the prescribing doctor in nearly 60% of hospitals. In terminal patients who could not go to the hospitals, caregivers were permitted to collect the opioids on behalf of patients in nearly 80% of hospitals. CONCLUSION: Our results illustrate that the regulation of opioids in government hospitals is mainly dependent on physician judgment. Patients can only receive oral morphine at a hospital pharmacy.

Palliative care and essential drug availability: Thailand national survey 2012.

BACKGROUND: Palliative care in Thailand was not well established in the past, but it is better supported by many organizations at present. Despite the change in the situation, the availability of essential drugs for palliative care has not been well studied. OBJECTIVE: Our aim was to update the medical community on the current situation of essential drug availability for palliative care in Thai hospitals. METHODS: The International Association for Hospice and Palliative Care (IAHPC) list of 34 essential drugs for palliative care was used in this survey. RESULTS: Five hundred and fifty-five hospitals replied to the questionnaire (response rate 57%). Eleven of the 24 nonopioid drugs were available above 90% in all hospitals. However, nonopioid drugs generally were less available in community hospitals (CH) and general hospitals (GH) than in large hospitals (LH). Tramadol was the most available weak opioid. Injectable morphine was the most available form of strong opioid in Thailand (96.9%). For the overall picture of oral morphine, immediate-release morphine was a less available form than the controlled-release form (32.2% versus 51.0%). Controlled-release oral morphine had a nearly two-fold better availability than immediate-release oral morphine in CH, GH, and LH, that is, cancer centers (CC), medical school hospitals (MH), regional hospitals (RH), and other government hospitals. In contrast, in private hospitals (PH), there was no difference between the availability of the controlled-release form and the immediate-release form. Transdermal fentanyl and methadone were also less available in Thailand (14.6% versus 16.5%, respectively). CONCLUSION: LH and PH have better overall nonopioid and opioid medication availability than CH and GH.

Palliative care personnel and services: a national survey in Thailand 2012.

Research on palliative care services in Thailand is incomplete. We conducted a countrywide cross-sectional postal survey to update the situation. We approached hospitals and asked them to respond to a questionnaire. The overall response rate of government hospitals was 61 percent (537 of 882 hospitals). Of these, 59 percent reported that they had personnel trained in palliative care; the majority had received less than a week of such training. In all, 60 percent of the hospitals reported that they offered palliative care services, but 25 percent of these services were delivered by staff who had no palliative care training. The criteria of having at least one trained doctor and nurse on staff was met by 17 percent of the hospitals. Only seven hospitals, most of them associated with medical schools, employed both a doctor and a nurse who had been trained in palliative care for one month or more; these professionals mainly provided hospital and home palliative care team services. Our survey reveals the lack of both health care personnel fully trained in palliative care and specialist palliative care services in Thailand.
