Herpes zoster (HZ) causes significant morbidity, particularly in older adults. With the advent of a recombinant zoster vaccine, HZ is potentially preventable. However, data on HZ burden and healthcare utilization in primary care populations remains scarce. This study described the prevalence and healthcare utilization in managing HZ in a developed community. A retrospective database review was conducted across a cluster of 8 public primary care clinics in urban Singapore. Data of multi-ethnic Asian patients with a diagnosis code of "herpes zoster" from 2018 to 2020 was extracted from their electronic medical records. Socio-demographic, clinical, visitation, medical leave, prescription, and referral data were analyzed. A total of 2,987 out of 737,868 individuals were diagnosed with HZ over 3 years. The mean age was 59.9 (SD + 15.5) years; 49.2% were male; 78.5% Chinese, 12.2% Malay, and 4.1% Indian. The prevalence was 221, 224, 203 per 100,000 persons in 2018, 2019, and 2020, respectively. The 70 to 79-year age group had the highest prevalence (829/100,000) across 3 years. Oral acyclovir (median daily dose 4,000 mg; median duration 7 days) and topical acyclovir were prescribed in 71.6 and 47.6%, respectively. Analgesia prescribed were gabapentin (41.0%), paracetamol combinations (30.1%), oral NSAIDs (23.7%), opioids (6.0%), and tricyclic antidepressants (1.9%). Most individuals consulted only once (84.3%); 32.7% of them required medical leave and 5.6% had more than 7 days of absenteeism. HZ-related referrals to the hospital were required in 8.9% (4.9% emergency, 2.8% ophthalmology). The findings of this study suggest a need for HZ vaccination among older age groups. Visitation and referral rates were low. The use of topical acyclovir was uncovered, and further research should evaluate the underlying reasons, benefits, and harms of such practice. The use of analgesia combinations may be explored further.

Background: Gout is associated with significant morbidity and mortality, yet suboptimal gout control remains a problem globally. Identifying the risk factors associated with poor gout control among patients in primary care allows targeted interventions to improve their clinical management. This study aimed to determine the prevalence of poor gout control and its associated demographic and clinical factors among urbanized community-dwelling Asian patients. Methods: This retrospective study was based on data extracted from the electronic medical records of 8 public primary care clinics in Singapore. Patients with a diagnostic code of gout who had 2 or more visits between 1st January 2018 and 31st December 2019 were included in the analysis. Data extracted included: demographics, anthropological measurements, comorbidities, serum uric acid levels and medication prescription. A patient is defined to have poor gout control if they suffer two or more acute gout attacks within a year. Chi-Squared test was used for categorical parameters. For continuous variables, univariate logistic regression analysis was first performed. Significant factors (p ≤ 0.1) were then included in the logistics regression model to account for confounders. Results: A total of 7,970 patients and 24,624 visits were included in the analysis. The prevalence of poorly controlled gout was 28.2% (n = 2,244/7,970); only 46.3% of them (n = 1,039/2,244) were prescribed allopurinol and 13.4% (n = 301/2,244) were taking doses ≥300 mg. Using logistic regression, factors associated with poor gout control were: male gender [adjusted OR (AOR) =1.66, p < 0.001], Malay ethnicity (AOR = 1.27, p = 0.007), congestive heart failure (AOR = 1.64, p = 0.037). Patients prescribed allopurinol (AOR = 1.52, p < 0.001), NSAIDs (AOR = 2.76, p < 0.001) and corticosteroids (AOR = 2.83, p < 0.001) were more likely to have poorly-controlled gout. Conclusion: Nearly 30% of patients had poor gout. Interventions should focus on male and Malay patients and those with congestive cardiac failure.

Background: Acne vulgaris (acne) is common among young persons (YPs). Clinical practice guidelines are available for acne management to minimize their physical and psychological impact. However, evidence of adherence to these guidelines is sparse in primary care practices. The study aimed to determine the demographic profile of YPs who sought primary care consultations for acne, their related prescriptions and referrals to specialists for further management. Method: A retrospective study was conducted using data from a cluster of eight public primary care clinics in Singapore. Demographic, clinical, prescription, and referral data were extracted from the electronic health records of YPs aged 10-29 years with a documented diagnosis of acne (ICD-10 classification) from 1st July 2018 to 30th June 2020. The data were reviewed, audited for eligibility criteria, and de-identified before analysis. Results: Complete data from 2,700 YPs with acne were analyzed. Male (56.1%) YPs and those of Chinese ethnicity (73.8%) had the most frequent attendances for acne. The mean and median age at presentation was 19.2 (standard deviation = 4.3) and 19 (interquartile range = 16-22) years, respectively. Only 69.7% of YPs received an acne-related medication; 33.5% received antibiotic monotherapy; 53.0% were prescribed oral doxycycline, 35.0% acne cream (combination of sulfur, salicylic acid, and resorcinol), and 28.4% benzoyl peroxide 5% gel; 54.3% of those treated with antibiotics were prescribed with a shorter duration than recommended; 51.3% were referred to a dermatologist on their first visit, and 15.8% had more than one visit. Conclusion: Acne management for YPs can be enhanced with refresher training among primary care physicians for better adherence to its clinical practice guidelines.
RÉSUMÉ
The study aimed to determine the resilience of multi-ethnic, multi-cultural adolescent students in cosmopolitan Singapore, their coping abilities, and the impact on their social and physical activities during the COVID-19 pandemic and its association with their resilience. A total of 582 adolescents in post-secondary education institutes completed an online survey from June to November 2021. The survey assessed their sociodemographic status, resilience level using the Brief Resilience Scale (BRS) and Hardy-Gill Resilience Scale (HGRS), the impact of the COVID-19 pandemic on their daily activities, life settings, social life, social interactions, and coping ability in these aspects of life. Poor ability to cope with school life (adjusted beta = - 0.163, 95% CI - 1.928 to 0.639, p < 0.001), staying home (adjusted beta = - 0.108, 95% CI = - 1.611 to - 0.126, p = 0.022), sports (adjusted beta = - 0.116, 95% CI - 1.691 to - 0.197, p = 0.013) and friends (adjusted beta = - 0.143, 95% CI - 1.904 to - 0.363, p = 0.004) were associated with statistically significant low resilience level measured with HGRS. About half and a third of the participants reported normal and low resilience, respectively, based on BRS (59.6%/32.7%) and HGRS (49.0%/29.0%) scores. Adolescents of Chinese ethnicity and low socioeconomic status had comparatively lower resilience scores. Approximately half of the adolescents in this study had normal resilience despite the COVID-19 pandemic. Adolescents with lower resilience tended to have lower coping abilities. The study did not compare changes in the social life and coping behaviour of the adolescents due to COVID-19, as data on these aspects prior to the pandemic was unavailable.

Background: Women of childbearing age may face unintended pregnancy (UP). They are usually referred by primary care professionals (PCPs) to gynecologists to manage their UP in countries where abortion is legalized. The study aimed to determine the prevalence, demographic profiles, and associated factors of women in a developed community seeking referrals from PCPs for their UP. Methods: The sociodemographic and clinical data were extracted from the electronic medical records of pregnant multi-ethnic Asian women at eight Singapore public primary care clinics from July 2017 to June 2020. Their demographic profiles were reviewed and compared among women of different age bands using appropriate statistical tests. Logistic regression was used to identify the factors associated with UP referrals. Results: Among 9,794 gravid women, 974 of them requested gynecologist referrals to terminate UP over the 3-year period, constituting a prevalence of 9.94%. The mean age of women requesting such referrals was 29.7 ± 7 years. There were 10.7% with more than one prior unintended pregnancy and 15.7% were foreigners. The majority of these women were married, neither required social assistance nor had comorbidities. Only 2.9% of them were known to be prescribed contraceptives. A multivariable logistic regression analysis showed that women of Indian ethnicity, single, aged below 20 years and above 40 years, were more likely to request referrals for UP. Conclusion: One in 10 gravid women had sought referrals for UP, especially adolescents and older women, and Indian ethnicity. An accessible community-based healthcare service to educate and counsel women on family planning is urgently needed to reduce the incidence of UP.

Changes to the national childhood immunization schedule (NCIS) can have a potential impact on vaccine uptake in the community. The NCIS in Singapore has undergone several revisions over the years, with the most recent modification on 1 November 2020. The new NCIS includes, as routine, the influenza and the varicella vaccine, as well as two combination vaccines, the measles, mumps, rubella and varicella vaccine (MMRV), and the hexavalent diphtheria, acellular pertussis, tetanus, haemophilus influenza b, injectable polio, and hepatitis B vaccine (6-in-1). This retrospective database study aims to assess the effect of the new NCIS on (a) the vaccination uptake of children at 6 and 12 months and (b) the cost difference to the healthcare system and to parents. One-year vaccination data from two cohorts of children immunized according to the old (n = 10,916) and new NCIS (n = 10,299) were extracted, respectively, from their electronic medical records. The vaccine uptake at 6 and 12 months increased by 10.8 and 2.1%, respectively, with the new NCIS as compared to the old NCIS. The mean number of required visits to the primary care clinic for each child was reduced from six to four. There is an estimated 6.41% cost reduction with the new NCIS.
RÉSUMÉ
Background: COVID-19 vaccination is a key public health measure to mitigate the crippling effects of the pandemic. COVID-19 vaccination began in adults and targeted adolescents at a later stage. However, medical decision-making on its uptake among the latter was unknown, which could be affected by their literacy and concerns about the vaccine. The study aimed to elucidate the awareness, concerns and barriers of adolescents toward the COVID-19 vaccine. Methods: A cross-sectional online survey using a self-developed questionnaire was conducted between June to November 2021. The adolescent participants were students from institutes of post-secondary education who were recruited via convenience sampling. The data were collated from an officially approved electronic platform, audited and analyzed. Continuous and categorical variables were expressed as mean (standard deviation) and percentages, respectively. Results: A total of 460 adolescents participated in the study (mean age: 16.99 ± 0.99; 73% female). Most of them (91.5%) were aware of the COVID-19 vaccines. The main barriers to vaccination were uncertainty about long-term health risks (38.6%) and vaccine efficacy (37.3%). Regarding the potential vaccine side effects, they were concerned about: anaphylactic shock (73.2%), low blood pressure (58.3%) and fast heartbeat (58.0%). Only 58% expressed willingness for repeated COVID-19 vaccination. Conclusion: Despite high COVID-19 vaccine awareness, the adolescents were concerned about the potentially severe but rare side-effects. The study identified apprehension regarding vaccine efficacy and the potential long-term health impact as the main barriers to vaccination. Future studies should address these concerns to scale vaccination programs among adolescents.
