Perceived stress and associated factors among healthcare workers in a primary healthcare setting: the Psychological Readiness and Occupational Training Enhancement during COVID-19 Time (PROTECT) study.

INTRODUCTION: Disease outbreaks such as the COVID-19 pandemic significantly heighten the psychological stress of healthcare workers (HCWs). The objective of this study was to understand the factors contributing to the perceived stress levels of HCWs in a public primary care setting during the COVID-19 pandemic, including their training, protection and support (TPS), job stress (JS), and perceived stigma and interpersonal avoidance. METHODS: This cross-sectional study using an electronic self-administered questionnaire was conducted at the National Healthcare Group Polyclinics in March 2020. Data was collected anonymously. Analysis was performed using regression modelling. RESULTS: The response rate was 69.7% (n = 1,040). The mean perceived stress level of HCWs in various departments ranged from 17.2 to 20.3. Respondents who reported higher perceived stress were those who made alternative living arrangements, were more affected by the current pandemic, reported higher JS and were Muslims. Respondents who reported lower perceived stress were those who had been through the severe acute respiratory syndrome epidemic in 2003 and H1N1 pandemic in 2009 as HCWs, and those who had higher confidence in the organisation's TPS. CONCLUSION: All HCWs, regardless of their scope of work, were similarly stressed by the current pandemic compared to the general population. Improving the confidence of HCWs in their training, protection and the support of personal protective equipment, and retaining experienced HCWs who can provide advice and emotional support to younger colleagues are important. Adequate psychological support for HCWs in the pandemic can be transformed into reserves of psychological resilience for future disease outbreaks.

Medication adherence and glycemic control among newly diagnosed diabetes patients.

BACKGROUND: Poor medication adherence can have negative consequences for the patients, the provider, the physician, and the sustainability of the healthcare system. To our knowledge, the association between medication adherence and glycemic control among newly diagnosed diabetes patients has not been studied. This study aims to bridge the gap. METHOD: This is a retrospective cohort study of 2463 patients managed in the National Healthcare Group in Singapore with newly diagnosed diabetes. Patients were followed up for the first two years from their first medication dispensed for measuring medication adherence, proportion of days covered (PDC); and for another three years for investigating outcomes of glycemic control, emergency department visit, and hospitalization. Multivariable regressions were performed to study the association between medication adherence and the outcomes as well as the risk factors of poor adherence. RESULTS: The prevalence of medication adherence (PDC≥80%) was 65.0% (95% CI 63.1% to 66.9%) among newly diagnosed diabetes patients in Singapore. Male, Indian, or patients without hypertension or dyslipidemia were associated with poorer medication adherence. The HbA1c level of poor adherent patients (PDC <40%) increased by 0.4 (95% CI 0.2 to 0.5) over the two years, and they were also more likely to have hospitalization (OR 2.6,95% CI 1.7 to 3.8) or emergency department visit (OR 2.4,95% CI 1.7 to 3.4) compared with the fully adherent patients (PDC=100%). CONCLUSIONS: The medication adherence in the early stage of diabetes is important for maximizing the effectiveness of pharmaceutical therapy. Health policies or interventions targeting the improvement of medication adherence among newly diagnosed diabetes patients are in need.

Singapore's regional health systems-a data-driven perspective on frequent admitters and cross utilization of healthcare services in three systems.

INTRODUCTION: With population health management being a priority in the Singapore, this paper aims to provide a data-driven perspective of the population health management initiatives to aid program planning and serves as a baseline for evaluation of future implemented programs. METHODS: A database with information on patient demographics, health services utilization, cost, diagnoses and chronic disease information from 2008 to 2013 for three regional health systems in Singapore was used for analysis. Patients with three or more inpatient admissions were considered as "Frequent Admitters." Health service utilization was quantified, and cross utilization of services was studied. One-year readmission rate for inpatients was studied, and a predictive model for readmission or death was developed. RESULTS: There were a total of 2.8 M patients in the database. Frequent admitters accounted for 0.9% of all patients with an average cost per patient of S$29 547. Of these, 89% had chronic diseases. Cross utilization of health services showed that 8.2% of the patients utilized services from more than one hospital with 19.6% utilizing hospital and polyclinic services in 2013. The highest risk of readmission or death was for those patients who had five or more inpatient episodes in each of the preceding 2 years. CONCLUSION: By understanding the profile of the patients and their utilization patterns in the three regional health systems, our study will help clinicians and decision makers design appropriate integrated care programs for patients with the aim of covering the healthcare needs for the enitre population across the healthcare spectrum in Singapore.

Annual all-cause mortality rate for patients with diabetic kidney disease in Singapore.

BACKGROUND: The prognosis of diabetic kidney disease is poor because epidemiological data have shown that all-cause mortality increases with declining renal function. This study aims to estimate the annual mortality rate of diabetic kidney disease stratified by chronic kidney disease (CKD) stages and to identify the predictors of mortality. METHODS: Patients with Stage 3-5 CKD (estimated glomerular filtration rate [eGFR] less than 60 mL/min per 1.73 m2) with diabetic kidney disease from the National Healthcare Group CKD Registry from 1 January 2007 to 31 December 2007 were included in this study. The patients were followed up till 30 November 2013. Cox's proportional hazards regression modelling was used to assess the factors associated with all-cause mortality. RESULTS: Over a median follow up period of 6.0 years, 985 out of 3008 patients (32.8%) died. Of those who died, 363 (36.9%) died from cardiovascular causes. The annual mortality rate was 64.1 per 1000 individuals (95% confidence interval [CI] 60.2-68.3) and the mortality rate increased with severity of CKD [Stage 3A (37.0), Stage 3B (57.5), Stage 4 (98.3) and Stage 5 (198.5)]. Predictors of mortality were age, male gender, CKD stages, albuminuria, comorbid conditions such as peripheral vascular disease, neuropathy, retinopathy and the use of antiplatelet agents. CONCLUSION: Our study estimated the annual all-cause mortality rate for Singaporean patients with diabetic kidney disease by CKD stages and identified predictors of all-cause mortality. This study has affirmed the poor prognosis of these patients and an urgency to intervene early so as to retard the progression to later stages of CKD.

Quality of care of patients with chronic kidney disease in national healthcare group polyclinics from 2007 to 2011.

INTRODUCTION: Chronic kidney disease (CKD) is a major public health problem where majority of patients are managed in the primary care. The major risk factors are advanced age, hypertension and diabetes mellitus, and risk factors control is paramount to prevent progression to CKD. The objective of the study is to describe the epidemiology and quality of care of patients with CKD stages 3 to 5 at National Healthcare Group Polyclinics (NHGP). MATERIALS AND METHODS: The study was carried out using data from National Healthcare Group (NHG) Renal Registry. Patients were included if they were identified to have CKD based on ICD-9-CM codes and laboratory results. RESULTS: Overall, the number of CKD patients increased more than 2 fold from 4734 in 2007 to 10,245 in 2011. In 2011, the majority belonged to stages 3A (39.6%) and 3B (37.6%), had hypertension (98.2%), dyslipidemia (97.2%) and diabetes mellitus (68.7%). From 2007 to 2011, among those with hypertension, the use of angiotensin converting enzyme (ACE) inhibitors and/ or angiotensin receptor blockers increased from 78.4% to 84.1%, and the percentage with good systolic blood pressure control (<130 mmHg) improved from 18.7% to 36.3%. Among those with dyslipidemia, the use of statins increased from 81% to 87.1%, and the percentage of patients with low density lipoproteins (LDL) <2.6 mmol/L increased from 40% to 54.7%. However, among those with diabetes mellitus, mean glycated haemoglobin (HBA1c) increased from 7.4% to 7.6%, and the percentage of patients with HBA1c ≤7.0% decreased from 44.5% to 39.4%. CONCLUSION: The number of CKD patients in NHGP has increased significantly from 2007 to 2011 at an average annual rate of 21.3%. Majority of patients the study conducted in 2011 were in stage 3A and stage 3B. Blood pressure and LDL control are encouraging but glycaemic control can be further improved.

Postgraduate family medicine training in Singapore--a new way forward.

Postgraduate Family Medicine (FM) training is important to train future primary care doctors to provide accessible and cost effective healthcare. In Singapore, a structured postgraduate FM training programme has been available for 20 years. This programme is characterised by involvement of both FM and non-FM doctors, well written modules and a rigorous assessment process. However, challenges faced by both the current healthcare system and training structure underlie the need to review the training structure to ensure its relevancy for future Family Physicians (FPs) to manage the needs of their patients. A workgroup was formed to review the current FM postgraduate programme and to explore the possibility of using the Accreditation Council for Graduate Medical Education (ACGME) framework to enhance our current system. The workgroup felt that broad-based training and comprehensive coverage of topics are areas that are important to retain in any new FM residency programme. Weaknesses identified included a lack of early FM exposure and the need to strengthen formative assessments. New organisational structures such as Family Medicine Centres (FMC) need to be established and the involvement of the private sector in any FM residency progammes could be enhanced. The implementation of the FM Residency Programme in 2011 presented a unique opportunity to realign FM postgraduate education in line with the national objectives and to equip FPs with the necessary knowledge and skills for managing the future healthcare needs of Singaporeans.

Psychosocial and coping responses within the community health care setting towards a national outbreak of an infectious disease.

OBJECTIVE: The psychological and coping responses of the noninfected community towards infectious disease outbreaks are relatively understudied. This cross-sectional study sought to determine the prevalence of severe acute respiratory syndrome (SARS)-related psychiatric and posttraumatic morbidities and associated coping styles within the general population visiting community health care services. METHODS: It was conducted on individuals attending community polyclinics in Singapore within the first week of July 2003, 16 weeks after the first national outbreak of SARS. The General Health Questionnaire-28, Impact of Event Scale-Revised, and Brief COPE were used to determine the prevalence rates of psychiatric and posttraumatic morbidities and employed coping strategies respectively. RESULTS: The overall response rate was 78.0%. Of the 415 community health care setting respondents, we found significant rates of SARS-related psychiatric (22.9%) and posttraumatic morbidities (25.8%). The presence of psychiatric morbidity was associated with the presence of high level of posttraumatic symptoms [adjusted odds ratio (OR) 2.26, 95% confidence interval (CI) 1.24-4.13, P=.008]. Psychiatric morbidity was further associated with being seen at fever stations (adjusted OR 1.90, 95% CI 1.08-3.34, P=.026), younger age (adjusted OR 0.97, 95% CI 0.94-0.98, P=.021), increased self blame (adjusted OR 1.67, 95% CI 1.22-2.28, P=.001), less substance use (adjusted OR 0.74, 95% CI 0.56-0.98, P=.034) and posttraumatic morbidity was associated with increased use of denial (adjusted OR 1.31, 95% CI 1.04-1.67, P=.024), and planning (adjusted OR 1.51, 95% CI 1.16-1.95, P=.002) as coping measures. CONCLUSION: These findings could potentially inform the development of practical community mental health programs for future infectious disease outbreaks.

Impact of the Singapore National Asthma Program (SNAP) on preventor-reliever prescription ratio in polyclinics.

INTRODUCTION: The Singapore National Asthma Program (SNAP) was launched in 2001 to address the high burden of asthma in Singapore. One component of the SNAP was directed at improving asthma control in the community by promoting preventive treatment with inhaled corticosteroids. This paper describes the program on prescription patterns of preventor and reliever medication for asthma in the polyclinics. MATERIALS AND METHODS: We monitored the prescription pattern for asthma as the preventor-reliever (PR) drug ratio. The PR ratio was employed both as a positive feedback tool and as a key performance indicator (KPI) for the program. Individual clinics were encouraged to implement locally relevant and effective initiatives to increase the KPI and facilitate this process. The different methods included chronic care models, multidisciplinary teams, enhanced primary care clinics, pre-counselling screening, decision support tools, self-management support, a patient information system and community education. RESULTS: In the course of the program, the case load for asthma in the polyclinics increased by 31%. During the same period, the average PR ratio increased significantly from 0.68 to 1.80 (P <0.001). CONCLUSIONS: A simple audit and positive feedback program based on PR ratios, accompanied by sustained local quality improvement cycles has been associated with a significant shift in the drug treatment of asthma away from episodic quick relief medication towards long-term daily preventive treatment with inhaled steroids in polyclinics.

Severe acute respiratory syndrome-related psychiatric and posttraumatic morbidities and coping responses in medical staff within a primary health care setting in Singapore.

BACKGROUND: Severe acute respiratory syndrome (SARS) is a major new infectious disease of this century that is unique in its high morbidity and concentration in health care settings. We aimed to determine the level of psychological impact and coping styles among the medical staff in a primary health care setting. METHOD: Using a structured questionnaire, we conducted a cross-sectional survey of the doctors and nurses working within a public, primary health care setting in mid-July 2003. The main outcome measures were rates of psychiatric morbidity, level of posttraumatic stress symptoms, and coping strategies. RESULTS: The response rate was 92.0%. Of the 277 respondents (91 doctors and 186 nurses), psychiatric morbidity and posttraumatic morbidity were found in 20.6% and 9.4%, respectively. Both psychiatric and posttraumatic morbidities were associated with higher scores on coping efforts including self-distraction, behavioral disengagement, social support, venting, planning, and self-blame (all p <.001), but not with direct exposure factors such as contact with suspected SARS patients or working in fever rooms/tentages. Multivariate analysis showed that psychiatric morbidity was associated with post-traumatic morbidity (p =.02) and denial (p =.03), whereas posttraumatic morbidity was associated with younger age (p =.007), being married (p =.02), psychiatric morbidity (p =.02), self-distraction (p =.02), behavioral disengagement (p =.01), religion (p =.003), less venting (p =.04), less humor (p =.04), and less acceptance (p =.02). CONCLUSION: SARS-related psychiatric and posttraumatic morbidities were present in the medical staff within a primary health care setting. Specific coping efforts, age, and marital status, not direct exposure factors, were associated with psychological morbidity. These findings provide possible foci for early identification and psychological support.

Acute respiratory symptoms in adults in general practice.

BACKGROUND: Community studies have shown that approximately 30% of patients with acute respiratory tract symptoms have no identifiable infective aetiology. This may not be applicable in general practice. OBJECTIVE: The purpose of this study was to determine the infective aetiology in patients who presented to primary care doctors with acute respiratory symptoms. METHODS: A prospective study was carried out in all nine primary care clinics belonging to the National Healthcare Group Polyclinics (NHGPs) in Singapore. The subjects comprised 594 consecutive patients (318 males, 276 females) aged > or = 21 years who presented with complaints of any one of cough, nasal or throat symptoms of <7 days duration. Data collection was through interview using structured questionnaire, physical examination, throat swabs for bacterial culture and nasal swabs for virus identification by immunofluorescence (IF) and polymerase chain reaction (PCR). Additional PCR was performed on a subsample of 100 patients. Patients were followed-up until resolution of symptoms. RESULTS: The aetiological diagnosis by infective agent is as follows: 150 patients (25.2%) had virus infections, of which 90.7% (136/150) were by rhinovirus. Fourteen patients (2.4%) had bacterial infections, of which 10 were due to group G streptococcus. Group A streptococcus was not detected. Nineteen patients with new pathogens were identified by further PCR. These included parainfluenza 4, human coronavirus OC43, adenovirus, enterovirus and Chlamydia pneumoniae. No pathogen could be identified in 49% of patients. There were no differences in clinical presentation and socio-demographic variables between patients who had viral infections and those in whom no pathogen could be identified. CONCLUSION: In about half of patients who presented at NHGPs, no pathogens could be identified even after PCR. A non-infective aetiology could be considered in these patients.
