Coordinated responses of academic medical centres to pandemics: Sustaining medical education during COVID-19.

Background: The Corona Virus Disease-19 (COVID-19) has been declared a pandemic by the World Health Organization (WHO). We state the consolidated and systematic approach for academic medical centres in response to the evolving pandemic outbreaks for sustaining medical education.Discussion: Academic medical centres need to establish a 'COVID-19 response team' in order to make time-sensitive decisions while managing pandemic threats. Major themes of medical education management include leveraging on remote or decentralised modes of medical education delivery, maintaining the integrity of formative and summative assessments while restructuring patient-contact components, and developing action plans for maintenance of essential activities based on pandemic risk alert levels. These core principles must be applied seamlessly across the various fraternities of academic centres: undergraduate education, residency training, continuous professional development and research. Key decisions from the pandemic response teams that help to minimise major disruptions in medical education and to control disease transmissions include: minimising inter-cluster cross contaminations and plans for segregation within and among cohorts; reshuffling academic calendars; postponing or restructuring assessments.Conclusions: While minimising the transmission of the pandemic outbreak within the healthcare establishments is paramount, medical education and research activities cannot come to a standstill each time there is a threat of one.

Perioperative pregabalin does not reduce opioid requirements in total knee arthroplasty.

PURPOSE: The purpose of this prospective, randomized, double-blinded, placebo-controlled study was to determine if pregabalin, when given perioperatively in addition to patient-controlled analgesia morphine, paracetamol and etoricoxib, is effective in reducing morphine requirements and moderating pain scores after primary total knee arthroplasty. We hypothesize that there would be no difference in postoperative opioid requirements, postoperative pain scores, and functional scores with the use of perioperative pregabalin. METHODS: Eighty-seven patients who underwent primary total knee arthroplasty were randomised and allocated to two groups. One group received capsules containing pregabalin 75 mg, and the other a placebo-one capsule before surgery and one capsule once per night up till postoperative day 2. Multimodal analgesia provided for all patients in this study included femoral nerve block, intravenous patient-controlled analgesia (morphine), paracetamol and etoricoxib. The primary outcome of patient's pain control was based on the measurement of cumulative morphine consumption during the first 72 h postoperatively. RESULTS: Pregabalin did not reduce the cumulative or effective morphine consumption at 48 h and 72 h post-operation. There were also no significant differences noted in pain scores at 48 h and 72 h after surgery, functional range of motion of the operated knee at 72 h post-op, or outcomes recorded on the Knee Society Score (KSS), Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) and 36-Item Short Form Survey (SF-36) questionnaires at 3 and 6 months post-op. None of the patients demonstrated common adverse reactions to pregabalin. CONCLUSION: This study showed no reduction in postoperative opioid requirements, or improvement in early postoperative pain scores or functional outcomes at 6 months, with perioperative use of pregabalin. Orthopaedic surgeons may consider this when selecting an analgesic regimen for their patients. LEVEL OF EVIDENCE: II.

Pain prevalence in Singapore.

UNLABELLED: The prevalence of chronic pain is well described in various parts of the world; primarily in Western societies such as Europe, America and Australia. Little is known of the prevalence of chronic pain within Asia or Southeast Asia. In view of the cultural and genetic variation in pain causation, manifestation and reporting, the findings of previous studies cannot be translated to Asian countries. Prevalence studies needed to be carried out to quantify the magnitude and impact of chronic pain within Asian countries to properly allocate precious health funds to deal with this important healthcare issue. We report the findings of the prevalence study within one Asian country: Singapore. OBJECTIVE: To determine the prevalence and impact of chronic pain in adult Singaporeans. MATERIALS AND METHODS: Two sets of questionnaires were designed. The first, a screening questionnaire, to identify the prevalence of chronic pain, and should there be chronic pain; the second, a detailed questionnaire was administered, to characterise the features and the impact of pain. A cross-sectional sampling of Singapore adults were achieved using a computer-based multi-step random sampling of listed telephones numbers. The questionnaires were administered via telephone by a trained interviewer with the aid of a computer-assisted telephone interview system. RESULTS: A total of 4141 screening and 400 detailed questionnaires were completed. The prevalence of chronic pain, defined as pain of at least 3 months' duration over the last 6 months was 8.7% (n = 359). There was a higher prevalence in females (10.9%) and with increasing age. In particular, pain prevalence increased steeply beyond the age of 65 years old. There was a significant impact on work and daily function of those with chronic pain. CONCLUSION: Though the prevalence of chronic pain was marginally lower compared other studies, the impact of pain was just as significant. In a rapidly ageing population such as Singapore, chronic pain is an important emerging healthcare problem which will likely exert increasing toll on the existing social infrastructure within the next 5 to 10 years.
