A rapid qualitative methods assessment and reporting tool for epidemic response as the outcome of a rapid review and expert consultation.

During the first year of the COVID-19 pandemic, the Methods Sub-Group of the WHO COVID-19 Social Science Research Roadmap Working Group conducted a rapid evidence review of rapid qualitative methods (RQMs) used during epidemics. The rapid review objectives were to (1) synthesize the development, implementation, and uses of RQMs, including the data collection tools, research questions, research capacities, analytical approaches, and strategies used to speed up data collection and analysis in their specific epidemic and institutional contexts; and (2) propose a tool for assessing and reporting RQMs in epidemics emergencies. The rapid review covered published RQMs used in articles and unpublished reports produced between 2015 and 2021 in five languages (English, Mandarin, French, Portuguese, and Spanish). We searched multiple databases in these five languages between December 2020 and January 31, 2021. Sources employing "rapid" (under 6 months from conception to reporting of results) qualitative methods for research related to epidemic emergencies were included. We included 126 published and unpublished sources, which were reviewed, coded, and classified by the research team. Intercoder reliability was found to be acceptable (Krippendorff's α = 0.709). We employed thematic analysis to identify categories characterizing RQMs in epidemic emergencies. The review protocol was registered at PROSPERO (no. CRD42020223283) and Research Registry (no. reviewregistry1044). We developed an assessment and reporting tool of 13 criteria in three domains, to document RQMs used in response to epidemic emergencies. These include I. Design and Development (i. time frame, ii. Training, iii. Applicability to other populations, iv. Applicability to low resource settings, v. community engagement, vi. Available resources, vii. Ethical approvals, viii. Vulnerability, ix. Tool selection); II. Data Collection and Analysis (x. concurrent data collection and analysis, xi. Targeted populations and recruitment procedures); III. Restitution and Dissemination (xii. Restitution and dissemination of findings, xiii. Impact). Our rapid review and evaluation found a wide range of feasible and highly effective tools, analytical approaches and timely operational insights and recommendations during epidemic emergencies.

Global Health System Resilience during Encounters with Stressors - Lessons Learnt from Cancer Services during the COVID-19 Pandemic.

AIMS: The protracted COVID-19 pandemic has overwhelmed health systems globally, including many aspects of cancer control. This has underscored the multidimensional nature of cancer control, which requires a more comprehensive approach involving taking a wider perspective of health systems. Here, we investigated aspects of health system resilience in maintaining cancer services globally during the COVID-19 pandemic. This will allow for health systems to be resilient to different types of system stressors/shocks in the future, to allow cancer care to be maintained optimally. MATERIALS AND METHODS: Using the World Health Organization health system framework (capturing aspects of service delivery, health workforce, information, medical products, vaccines and technologies, financing and governance and leadership), we carried out a comparative analysis of the impact of COVID-19 and the synthesis of the findings in responses in cancer care in 10 countries/jurisdictions across four continents comprising a wide diversity of health systems, geographical regions and socioeconomic status (China, Colombia, Egypt, Hong Kong SAR, Indonesia, India, Singapore, Sri Lanka, UK and Zambia). A combination of literature and document reviews and interviews with experts was used. RESULTS: Our study revealed that: (i) underlying weaknesses of health systems before the pandemic were exacerbated by the pandemic (e.g. economic issues in low- and middle-income countries led to greater shortage of medication and resource constraints compounded by inadequacies of public financing and issues of engagement with stakeholders and leadership/governance); (ii) no universal adaptive strategies were applicable to all the systems, highlighting the need for health systems to design emergency plans based on local context; (iii) despite the many differences between health systems, common issues were identified, such as the lack of contingency plan for pandemics, inadequate financial policies for cancer patients and lack of evidence-based approaches for competing priorities of cancer care/pandemic control. CONCLUSION: We identified four key points/recommendations to enhance the resilient capacity of cancer care during the COVID-19 pandemic and other system stressors: (i) effective pandemic control approaches in general are essential to maintain the continuity of cancer care during the emergency health crises; (ii) strong health systems (with sufficient cancer care resources, e.g. health workforce, and universal health coverage) are fundamental to maintain quality care; (iii) the ability to develop response strategies and adapt to evolving evidence/circumstances is critical for health system resilience (including introducing systematic, consistent and evidence-based changes, national support and guidance in policy development and implementation); (iv) preparedness and contingency plans for future public health emergencies, engaging the whole of society, to achieve health system resilience for future crises and to transform healthcare delivery beyond the pandemic.

Antibiotic use for respiratory tract infections among older adults living in long-term care facilities: a systematic review and meta-analysis.

BACKGROUND: Antibiotics are commonly prescribed for respiratory tract infections (RTIs) among older adults in long-term care facilities (LTCFs), and this contributes to the emergence of antimicrobial resistance. The objective of this study was to determine the antibiotic prescribing rate for RTIs among LTCF residents, and to analyse the antibiotic consumption patterns with the AwaRe monitoring tool, developed by the World Health Organization. METHODS: MEDLINE, EMBASE and CINAHL were searched from inception to March 2022. Original articles reporting antibiotic use for RTIs in LTCFs were included in this review. Study quality was assessed using the Joanna Briggs Institute's Critical Appraisal Checklist for Prevalence Data. A random-effects meta-analysis was employed to calculate the pooled estimates. Subgroup analysis was conducted by type of RTI, country, and study start year. RESULTS: In total, 47 articles consisting of 50 studies were included. The antibiotic prescribing rate ranged from 21.5% to 100% (pooled estimate 69.8%, 95% confidence interval 55.2-82.6%). The antibiotic prescribing rate for lower respiratory tract infections (LRTIs) was higher than the rates for viral and general RTIs. Compared with Italy, France and the USA, the Netherlands had lower antibiotic use for LRTIs. A proportion of viral RTIs were treated with antibiotics, and all the antibiotics were from the Watch group. Use of antibiotics in the Access group was higher in the Netherlands, Norway, Switzerland and Slovenia compared with the USA and Australia. CONCLUSION: The antibiotic prescribing rate for RTIs in LTCFs was high, and AWaRe antibiotic use patterns varied by type of RTI and country. Improving antibiotic use may require coordination efforts.

Peri-discharge complex interventions for reducing 30-day hospital readmissions among heart failure patients: overview of systematic reviews and network meta-analysis.

AIMS: An overview of systematic reviews (SRs) and network meta-analysis (NMA) was conducted to synthesize evidence of comparative effectiveness of different peri-discharge complex interventions for reducing 30-day hospital readmissions among heart failure (HF) patients. METHODS: We searched five databases for SRs from their inception to August 2019 and conducted additional search for randomized controlled trials (RCTs) published between 2003 and 2020. We used random-effect pairwise meta-analysis with pooled risk ratios (RRs) and 95% confidence intervals (CIs) to quantify the effect of complex interventions, and NMA to evaluate comparative effectiveness among complex interventions. Primary outcome was 30-day all-cause hospital readmissions, while secondary outcomes were 30-day HF-related hospital readmissions, 30-day mortality, and 30-day emergency department visits. RESULTS: From 20 SRs and additional RCT search, 21 eligible RCTs (n = 5362) assessing eight different peri-discharge complex interventions were included. Pairwise meta-analysis showed no significant difference between peri-discharge complex interventions and controls on all outcomes, except that peri-discharge complex interventions were significantly more effective than controls in reducing 30-day mortality (pooled RR = 0.68, 95% CI: 0.49-0.95, 5 RCTs). NMA indicated that for reducing 30-day all-cause hospital readmissions, supportive-educative intervention had the highest probability to be the best intervention, followed by disease management; while for reducing 30-day HF-related hospital readmissions, disease management is likely to be the best intervention. CONCLUSIONS: Our results suggest that disease management has the best potential to reduce 30-day all-cause and HF-related hospital readmissions. Benefits of the interventions may vary across health system contexts. Evidence-based complex interventions require local adaptation prior to implementation.

Evaluation of the implementation of information system for postdischarge with the theoretical domains framework by healthcare professionals: a multistage design with qualitative inquiry and Delphi expert discussion protocol.

INTRODUCTION: Improving discharge information dissemination may improve patients' health literacy of self-care and health outcomes, avoid unnecessary healthcare utilisation, and reduce the healthcare cost. This study aims to use an implementation science theory guided approach to examine the beliefs and behaviours of healthcare professionals regarding postdischarge information summary (PDIS) implementation in a public inpatient setting. METHODS AND ANALYSIS: A multistage study design involving qualitative inquiry and Delphi expert discussion will be used to systematically explore the perceived barriers in the four implemented hospitals and enable the full implementation of the PDIS in geriatric and medical care. The theoretical domains framework (TDF), behavioural change wheel and realistic evaluation framework will be used to guide the investigation of implementation. This study consists of three steps: (1) identifying barriers and enablers from an implementation perspective using a TDF-informed interview guide; (2) devising theory-based implementation strategy packages to facilitate the adoption and enhancement of PDIS by performing a strategy mapping exercise and (3) developing an effective implementation strategy package for scaling up PDIS in other target hospitals as well as other specialities using the Delphi expert discussion. The goal of this multistage study design is to identify the perspectives from healthcare professionals towards the PDIS implementation and explore their barriers and facilitators of the process in the pilot phase. The invited healthcare professionals would share their daily experience on providing PDIS to patient in various study hospitals with similar ward setting. The implementation of discharge intervention in a study setting through different steps to aid in the exploration and development of the modified implementation strategies for the adoption and enhancement of PDIS in the discharge process. ETHICS AND DISSEMINATION: Ethics approval for the study was obtained from the Joint Chinese University of Hong Kong-New Territories East Cluster Clinical Research Ethics Committees. Results of the study would be released as a report submitted to the Health and Medical Research Fund of Food and Health Bureau of the Hong Kong Government. The result would also be published in international peer-reviewed medical journals and presented in conferences. TRIAL REGISTRATION NUMBER: ChiCTR2000034382.

Caregiving burnout of community-dwelling people with dementia in Hong Kong and New Zealand: a cross-sectional study.

BACKGROUND: Informal caregiving for people with dementia can negatively impact caregivers' health. In Asia-Pacific regions, growing dementia incidence has made caregiver burnout a pressing public health issue. A cross-sectional study with a representative sample helps to understand how caregivers experience burnout throughout this region. We explored the prevalence and contributing factors of burnout of caregivers of community-dwelling older people with dementia in Hong Kong (HK), China, and New Zealand (NZ) in this study. METHODS: Analysis of interRAI Home Care Assessment data for care-recipients (aged ≥65 with Alzheimer's disease/other dementia) who had applied for government-funded community services and their caregivers was conducted. The sample comprised 9976 predominately Chinese in HK and 16,725 predominantly European in NZ from 2013 to 2016. Caregiver burnout rates for HK and NZ were calculated. Logistic regression was used to determine the adjusted odds ratio (AOR) of the significant factors associated with caregiver burnout in both regions. RESULTS: Caregiver burnout was present in 15.5 and 13.9% of the sample in HK and NZ respectively. Cross-regional differences in contributing factors to burnout were found. Care-recipients' ADL dependency, fall history, and cohabitation with primary caregiver were significant contributing factors in NZ, while primary caregiver being child was found to be significant in HK. Some common contributing factors were observed in both regions, including care-recipients having behavioural problem, primary caregiver being spouse, providing activities-of-daily-living (ADL) care, and delivering more than 21 h of care every week. In HK, allied-health services (physiotherapy, occupational therapy and speech therapy) protected caregiver from burnout. Interaction analysis showed that allied-health service attenuates the risk of burnout contributed by care-recipient's older age (85+), cohabitation with child, ADL dependency, mood problem, and ADL care provision by caregivers. CONCLUSIONS: This study highlights differences in service delivery models, family structures and cultural values that may explain the cross-regional differences in dementia caregiving experience in NZ and HK. Characteristics of caregiving dyads and their allied-health service utilization are important contributing factors to caregiver burnout. A standardized needs assessment for caregivers could help policymakers and healthcare practitioners to identify caregiving dyads who are at risk of burnout and provide early intervention.

Can voucher scheme enhance primary care provision for older adults: cross-sectional study in Hong Kong.

BACKGROUND: The Hong Kong government has launched the Elderly Health Care Voucher (EHCV) scheme to facilitate primary care in the private sector for older adults. This study aimed to examine whether voucher use was associated with a shift of healthcare burden from the public to the private sector, vaccine uptake and continuity of care. METHODS: This cross-sectional survey recruited older adults with ≥3 chronic diseases through convenience sampling from seven general outpatient clinics, seven geriatric day hospitals, and five specialist outpatient clinics of the public healthcare sector in Hong Kong. We used multiple logistic regression to address the study objective. RESULTS: A total of 1032 patients participated in the survey. We included 714 participants aged 70 or above in the analysis. EHCV use was associated with higher utilization of private primary care services, including general practitioner and family doctor (Adjusted Odds Ratio (AOR) 2.67, 95% Confidence Interval (95%CI) 1.51-4.72) and Chinese medicine clinic (AOR 3.53, 95%CI 1.47-8.49). There were no significant associations of EHCV use with public general outpatient clinic attendance, Accident & Emergency attendance, and hospitalization. Furthermore, EHCV users were more likely to receive pneumococcal vaccination (AOR 2.17, 95%CI 1.22-3.85) and were less likely to visit the same doctors for chronic disease management (AOR 0.10, 95%CI 0.01-0.73). CONCLUSIONS: While the EHCV may promote private primary care utilization and preventive care, older patients continue to rely on public services and the EHCV may worsen continuity of care. Policy-makers should designate voucher usage for chronic disease management and continuity of care.

Management decision of hospital surge: assessing seasonal upsurge in inpatient medical bed occupancy rate among public acute hospitals in Hong Kong.

BACKGROUND: There were recurrent upsurges in demand for public hospital services in Hong Kong. An understanding of the contribution of some possible factors for the rise in health care burden would help to inform hospital management strategies. AIM: To evaluate the utilization patterns of hospitalizations in medical wards among public acute hospitals in Hong Kong during surge periods. DESIGN: Retrospective study. METHODS: By extracting the information in press releases between 2014 and 2018, descriptive statistics about medical ward occupancy situation during six surge periods were generated. A time series model was constructed to estimate the occupancy rate at each hospital and assess its relationship with the intensity of seasonal influenza activity, extreme weather, day of week and long holidays. RESULTS: There was a significant increase in the number of admissions to medical wards in all six surge periods. A significant variation in occupancy rate between weekdays and geographic regions was observed. The occupancy rate in 10, out of 15, hospitals was significantly associated with the influenza activity, while there was limited effect of weather on the occupancy rate. A significant holiday effect was observed during Christmas and Chinese New Year, resulting in a lower bed occupancy rate. CONCLUSIONS: A differential burden in public hospitals during surge periods was reported. Contingency bed and staff management shall be tailored to individual hospitals, given their differences in the determinants for inpatient bed occupancy.

Benefits and limitations of implementing Chronic Care Model (CCM) in primary care programs: A systematic review.

BACKGROUND: Chronic Care Model (CCM) has been developed to improve patients' health care by restructuring health systems in a multidimensional manner. This systematic review aims to summarize and analyse programs specifically designed and conducted for the fulfilment of multiple CCM components. We have focused on programs targeting diabetes mellitus, hypertension and cardiovascular disease. METHOD AND RESULTS: This review was based on a comprehensive literature search of articles in the PubMed database that reported clinical outcomes. We included a total of 25 eligible articles. Evidence of improvement in medical outcomes and the compliance of patients with medical treatment were reported in 18 and 14 studies, respectively. Two studies demonstrated a reduction of the medical burden in terms of health service utilization, and another two studies reported the effectiveness of the programs in reducing the risk of heart failure and other cardiovascular diseases. However, CCMs were still restricted by limited academic robustness and social constraints when they were implemented in primary care. Higher professional recognition, tighter system collaborations and increased financial support may be necessary to overcome the limitations of, and barriers to CCM implementation. CONCLUSION: This review has identified the benefits of implementing CCM, and recommended suggestions for the future development of CCM.

Household cleaning products and the risk of allergic dermatitis: a prospective cohort study with primary-school children.

BACKGROUND: Household cleaning products are widely used by the public, but limited data have been obtained on whether their use induces allergic dermatitis in children. OBJECTIVE: This study investigated the association between exposure to household cleaning products and allergic dermatitis in primary-school children. METHODS: A prospective cohort study of Hong Kong primary-school children was conducted between 2012 and 2014. A baseline survey was administered to 1812 students who did not have allergic dermatitis. Information on respiratory symptoms, exposure to household chemical cleaning products and other topics was collected using a self-administered questionnaire. A cumulative chemical burden (CCB) score was calculated for each student by summing the duration of exposure to 14 chemical cleaning products. Principal component analysis was used to identify patterns in the use of these cleaning products. Logistic regression was performed to calculate relative risk (RR) with 95% confidence intervals (CIs) after adjusting for potential confounders. RESULTS: Eighty-nine (4.9%) of the students surveyed had dermatitis during the follow-up. However, exposure to individual chemical cleaning products was not found to be associated with the children's allergic dermatitis (all P > 0.05). In contrast to those in the lowest tertile, neither CCB scores in the middle tertile (RR: 1.16, 95% CI: 0.67 to 2.00) nor those in the highest tertile (RR: 1.24, 95% CI: 0.73 to 2.14) were significantly associated with the risk of allergic dermatitis. The adjusted RR for every 5-unit increment in CCB score was 1.01 (95% CI: 0.98 to 1.03). Four patterns of cleaning-product use were derived, but none were found to be associated with the risk of dermatitis (all P > 0.05). CONCLUSION: The use of household chemical cleaning products is not associated with the risk of dermatitis in primary-school children.

Validation of inpatient experience questionnaire.

OBJECTIVE: A validation survey was carried out in this study to assess the acceptability, validity and reliability of the Hong Kong Inpatient Experience Questionnaire (HKIEQ), which was newly developed to measure patient experiences of hospital care in Hong Kong (HK). DESIGN: Cross-sectional validation survey. MAIN OUTCOME MEASURES: Principal component exploratory factor analysis assessed the construct validity of the questionnaire. Cronbach's alpha coefficients and Spearman's rank correlation coefficient estimated the reliability of the instrument. Acceptability of the questionnaire regarding the percentage of missing value of individual items was also assessed. RESULTS: A total of 511 patients discharged from public hospitals in HK were interviewed. Low percentage of missing value (0.2 to 21.3%) showed high acceptability. Nine dimensions of hospital care explaining 75.4% of the variance were derived from factor analysis and content validity. These items showed satisfactory internal reliability consistency (0.49 to 0.97). Test-retest reliability ranged from 0.36 to 0.96. CONCLUSIONS: The HKIEQ performed well on several psychometric indicators and is a promising measure of patient experience with public hospital inpatient care in HK. The findings provided important insight on developing tools to measure patient experience in hospitals to improve the quality of care and to lay the foundation for further research on patient expectations and needs regarding hospitalization.

Altered fractionation outcomes for hypoxic head and neck cancer using the HYP-RT Monte Carlo model.

OBJECTIVE: Altered fractionation radiotherapy is simulated on a set of virtual tumours to assess the total doses required for tumour control compared with clinical head and neck data and the doses required to control hypoxic vs well-oxygenated tumours with different radiobiological properties. METHODS: The HYP-RT model is utilised to explore the impact of tumour oxygenation and the onset times of accelerated repopulation (AR) and reoxygenation (ROx) during radiotherapy. A biological effective dose analysis is used to rank the schedules based on their relative normal tissue toxicities. RESULTS: Altering the onset times of AR and ROx has a large impact on the doses required to achieve tumour control. Immediate onset of ROx and 2-week onset time of AR produce results closely predicting average human outcomes in terms of the total prescription doses in clinical trials. Modifying oxygen enhancement ratio curves based on dose/fraction significantly reduces the dose (5-10 Gy) required for tumour control for hyperfractionated schedules. HYP-RT predicts 10×1.1 Gy per week to be most beneficial, whereas the conventional schedule is predicted as beneficial for early toxicity but has average-poor late toxicity. CONCLUSION: HYP-RT predicts that altered radiotherapy schedules increase the therapeutic ratio and may be used to make predictions about the prescription doses required to achieve tumour control for tumours with different oxygenation levels and treatment responses. ADVANCES IN KNOWLEDGE: Oxic and hypoxic tumours have large differences in total radiation dose requirements, affected by AR and ROx onset times by up to 15-25 Gy for the same fractionation schedule.

Patient experiences with public hospital care: first benchmark survey in Hong Kong.

OBJECTIVE. To measure patient satisfaction in relation to in-patient experience in public hospitals. DESIGN. Cross-sectional study. SETTING. Twenty-five selected Hospital Authority acute and convalescence hospitals in Hong Kong. PARTICIPANTS. Eligible patients discharged between 15 June and 27 September 2010 from the selected Hospital Authority public hospitals. MAIN OUTCOME MEASURES. A total of 54 items were used to measure patient experience on aspects of hospital care. They included the process of admission to hospital, staying in the hospital and ward (environment, food and facilities; hospital staff; patient care and treatment), the process of leaving hospital, and the overall impression of hospital care. Free-text comments from respondents were also recorded. RESULTS. A total of 5030 patients were successfully interviewed, amounting to a response rate of 52%. The findings showed that 80% (confidence interval, 79-81%) of patients rated the care they received in hospital as good or better. However, there were a few areas where performance was relatively low, including waiting time for a ward bed for accident and emergency cases, food quality, infection control, information provided about their condition/treatment, seeking patient input about their opinions and quality of care, and patient engagement in the decisions about their treatment and care, as well as the discharge process. CONCLUSIONS. This patient experience survey used a validated instrument (Hong Kong Inpatient Experience Questionnaire) to provide important insights to executives and health care professionals on their care to patients and to identify areas for improvement in public hospitals. Further surveys should be carried out to monitor changes in patient experience and satisfaction on a regular basis. Such surveys could facilitate improvements through analysis of results on patient satisfaction.

Can vouchers make a difference to the use of private primary care services by older people? Experience from the healthcare reform programme in Hong Kong.

BACKGROUND: As part of its ongoing healthcare reform, the Hong Kong Government introduced a voucher scheme, intended for encouraging older patients to use primary healthcare services in the private sector, thereby, reducing burden on the overwhelmed public sector. The voucher program is also considered one of the strategies to further develop the public private partnership in healthcare, a policy direction of high political priority as indicated in the Chief Executive Policy Address in 2008-09. This study assessed whether the voucher scheme, as implemented so far, has reached its intended goals, and how it might be further improved in the context of public-private partnership. METHODS: This was a cross-sectional study using structured questionnaires by face-to-face interviews with older people aged 70 or above in Hong Kong, the target group of the demand-side voucher program. RESULTS: 71.2% of 1,026 older people were aware of the new voucher scheme but only 35.0% had ever used it. The majority of the older people used the vouchers for acute curative services in the private sector (82.4%) and spent less on preventive services. Despite the provision of vouchers valued US$30 per year as an incentive to encourage the use of private primary care services, after 12-months of implementation, 66.2% of all respondents agreed with the statement that "the voucher scheme does not change their health seeking behaviours on seeing public or private healthcare professionals". The most common reasons for no change in their behaviours included "I am used to seeing doctors in the public system" and "The amount of the subsidy is too low". Those who usually used a mix of public and private doctors and those with better self-reported health condition compared to last year were more likely to perceive a change in their own health seeking behaviours. CONCLUSIONS: Our study showed that despite a reasonably high awareness of the voucher scheme, its usage was low. The voucher alone was not enough to realize the government's policy of greater use of the private primary care services. Greater publicity and more variety of media promotion would increase awareness but the effectiveness of vouchers in changing older people's behaviour needs to be revisited. Designating vouchers for use of preventive services with evidence-based practice could be considered. In addition to the demand-side subsidies, improving transparency and comparability of private services against the public sector might be necessary.

Monte Carlo radiotherapy simulations of accelerated repopulation and reoxygenation for hypoxic head and neck cancer.

OBJECTIVE: A temporal Monte Carlo tumour growth and radiotherapy effect model (HYP-RT) simulating hypoxia in head and neck cancer has been developed and used to analyse parameters influencing cell kill during conventionally fractionated radiotherapy. The model was designed to simulate individual cell division up to 10(8) cells, while incorporating radiobiological effects, including accelerated repopulation and reoxygenation during treatment. METHOD: Reoxygenation of hypoxic tumours has been modelled using randomised increments of oxygen to tumour cells after each treatment fraction. The process of accelerated repopulation has been modelled by increasing the symmetrical stem cell division probability. Both phenomena were onset immediately or after a number of weeks of simulated treatment. RESULTS: The extra dose required to control (total cell kill) hypoxic vs oxic tumours was 15-25% (8-20 Gy for 5 × 2 Gy per week) depending on the timing of accelerated repopulation onset. Reoxygenation of hypoxic tumours resulted in resensitisation and reduction in total dose required by approximately 10%, depending on the time of onset. When modelled simultaneously, accelerated repopulation and reoxygenation affected cell kill in hypoxic tumours in a similar manner to when the phenomena were modelled individually; however, the degree was altered, with non-additive results. Simulation results were in good agreement with standard linear quadratic theory; however, differed for more complex comparisons where hypoxia, reoxygenation as well as accelerated repopulation effects were considered. CONCLUSION: Simulations have quantitatively confirmed the need for patient individualisation in radiotherapy for hypoxic head and neck tumours, and have shown the benefits of modelling complex and dynamic processes using Monte Carlo methods.

A population-based survey using PPE-15: relationship of care aspects to patient satisfaction in Hong Kong.

OBJECTIVE: Satisfaction with hospitalization may lead to both better health outcomes for patients and create better working environment and relationship between staff and patients. The objective of this study is to explore the relationship between the experiences of inpatients with specific aspects of care and satisfaction with the hospitalization experience. DESIGN: A secondary data analysis based on the Thematic Household Survey which was regularly conducted by the Census and Statistic Department. SETTING: This survey covered the land-based non-institutional population of the Hong Kong Special Administrative Region (HKSAR), China, and representing 99% of the total population of HKSAR of 6.8 million. PARTICIPANTS: Totally 1264 respondents aged ≥15 who had ever been admitted to local hospital in 12 months prior enumeration were recruited. MAIN OUTCOME MEASURES: The Picker Patient Experience Questionnaire-15 (PPE-15) was adopted for measuring patient-perceived quality of hospitalization; and one global rating of the overall quality of hospital service was included. RESULTS: The mean global satisfaction scores for public and private hospital care were 7.3/10 and 7.8/10, respectively. By adjusting patient demographics, the regression models show that 'want to be more involved in decision made about the care and treatment', 'respect for patient's dignity', 'patients' family have enough opportunity to talk to doctor' and 'tell about danger signals regarding illness/treatment after went home' are major determinants of the global satisfaction scores. CONCLUSION: Communication, respect and patient engagement in provider-patient relationship are important in determining patient's satisfaction. Training and healthcare education curriculum could take this into account for ensuring the quality of patient-centered care.

The development of a Health Call Centre in Hong Kong: a study on the perceived needs of patients.

OBJECTIVES: To assess the preference for the development of a Health Call Centre and the perceived needs of patients in Hong Kong. DESIGN: Cross-sectional, questionnaire-based survey. SETTING: Two general out-patient clinics from health facilities in a geographical region in Hong Kong. PARTICIPANTS: Patients aged 18 years or above were recruited for the study, which was conducted between January and March 2009. MAIN OUTCOME MEASURES: Patients' perspectives of a Health Call Centre, perceived needs for services, perceived health status, and socio-demographic status. RESULTS: A total of 403 participants completed the questionnaire with a response rate of 78%. A total of 342 (85%) supported the development of a Health Call Centre. Providing basic health and chronic disease information, current health conditions and treatment information, and caregiver support advice were cited as the top perceived needs on the development of a Health Call Centre. Adjusting for age, education, and individual monthly income, participants aged 31 to 64 years (odds ratio=4.37; 95% confidence interval, 1.92-9.99; P<0.001) and caregivers (odds ratio=3.41; 95% confidence interval, 1.21-9.59; P=0.020) were more likely to use the Health Call Centre. Presence of chronic illness had no significant correlation with the use of a Health Call Centre (odds ratio=1.43; 95% confidence interval, 0.69-3.00; P=0.340). CONCLUSIONS: This is the first study to assess the preferences for the development of a Health Call Centre and the perceived needs of patients in Hong Kong. The majority supported the development of a Health Call Centre. Services provided could meet the general needs of all patients and caregivers, and be accessible to old people.
