Factors Affecting the Levels of Satisfaction With Nurse-Patient Communication Among Oncology Patients.

BACKGROUND: Nurse-patient communication is of the utmost importance to oncology patients. OBJECTIVE: The aim of this study was to investigate the factors influencing the level of satisfaction with nurse-patient communication among oncology patients during their daily routine procedures. METHODS: In this observational study, 25 registered nurses and 94 patients were recruited from an oncology unit. The patients were asked to complete a concern checklist before and after each admission, administration of medication, and wound-dressing procedure. Nonverbal cues expressed by the nurses and patients were noted on the checklist during these nursing procedures. RESULTS: The results showed that patients at stage 3 cancer and patients receiving admission procedures were significantly more satisfied with their communication with nurses compared with those who were more concerned about the impact of the disease on self-care. CONCLUSIONS: Cancer stage, time of admission, and psychological concern related to self-care ability are the potential factors affecting the satisfaction level of nurse-patient communication. IMPLICATIONS FOR NURSING: Emphasis could be placed on utilizing the time of admission to interact with patients in a busy environment to strive for better communication with oncology patients. The results underscore the importance of applying the self-care enhancement approach for hospitalized cancer patients.

Influence of Urban Green Space and Facility Accessibility on Exercise and Healthy Diet in Hong Kong.

Background A cross-sectional study using a convenience sampling method was conducted to understand how green space and accessibility of common public open spaces in compact urban areas affect physical activity and healthy diets of residents. Methods A total of 554 residents completed a structured questionnaire on quality of life, physical activity level and healthy eating practice. Particularly, categories of physical activity and durations were obtained by using the short form Chinese International Physical Activity Questionnaire (IPAQ-C), then the Metabolic Equivalent of Task (MET)-minutes/week was calculated using the formulae (walking minutes × walking days × 3.3) + (moderate-intensity activity minutes × moderate days × 4.0) + (vigorous-intensity activity minutes × vigorous-intensity days × 8.0). The percentage of green space was calculated based on a spatial buffer with a 500 m radius from participants' geocoded addresses using a SPOT ('Satellite Pour l'Observation de la Terre' in French) satellite image-derived vegetation dataset. Parks, promenade and sports facilities were examples of open spaces. Results The sampled population who lived with green space averaged 10.11% ± 7.95% (ranged 1.56-32.90%), with the majority (90%) performing physical activities at medium and high levels. MET-minutes/week was significantly associated (Pearson r = 0.092; p < 0.05) with the green space percentage. Relatively active residents commonly used open spaces within the district for performing exercise, in particular, parks and promenades were mostly used by older residents, while sports facilities by the younger groups at age 25-44 and <25 years. Conclusions Current findings suggested promotion of exercise could be achieved by the design or redesign of built environment to include more parks accessible to the residents with the increase of vegetation.

Assessing quality of life using WHOQOL-BREF: a cross-sectional study on the association between quality of life and neighborhood environmental satisfaction, and the mediating effect of health-related behaviors.

BACKGROUND: Quality of life (QOL) is an important component in assessing people's health. Environmental quality can influence people's QOL in the physical health, psychological, social relationships and environment domains. QOL in the four domains, overall QOL and general heath of residents living in the Kowloon Peninsula of Hong Kong were assessed. The association between satisfaction with the neighborhood environment and QOL, and health-related behaviors which mediated the effect were investigated. METHODS: A sample of 317 residents completed a questionnaire which comprised the WHOQOL-BREF (Hong Kong version) to assess QOL, the International Physical Activity Questionnaire (IPAQ) to study physical activities, and questions on satisfaction with the neighborhood environment, health-related behaviors and socio-demographics. One-way ANOVA and linear regression were used to study the associations between environmental satisfaction and QOL in the four domains, overall QOL and general health, followed by assessing the relationships between environmental satisfaction and the potential health-related behavior mediators with regression tests. Mediation analysis was conducted using multiple linear regressions to study the effects of environmental satisfaction on QOL in the four domains, overall QOL and general health, as well as the potential mediating roles played by various health-related behaviors. A P-value of < 0.05 was considered as statistically significant. RESULTS: The residents had a relatively higher physical health mean score of 70.83 ± 12.69, and a lower environmental mean score of 61.98 ± 13.76. Moderate satisfaction with the neighborhood environment had a significant relationship with QOL in the psychological domain (ß = 0.170, P = 0.006), however, this effect was partially mediated by the non-smoking behavior of the residents (ß = 0.143, P = 0.022). CONCLUSIONS: Our residents had lower QOL in the physical health and psychological domains but similar QOL in the social relationships and environmental domains compared to other countries. Only QOL in the psychological domain could be predicted by the satisfaction with the neighborhood environment, and non-smoking status was a partial mediator of the effect of moderate environmental satisfaction on QOL in the psychological domain. Refrain from smoking seems to be able to lower the influence of neighborhood environment on people's QOL in the psychological domain to a certain extent.

Influence of Pokémon Go on physical activity levels of university players: a cross-sectional study.

BACKGROUND: The prevalence of overweight is increasing and the effectiveness of various weight management and exercise programs varied. An augmented reality smartphone game, Pokémon Go, appears to increase activity levels of players. This study assessed the players and ex-players' frequencies and durations of staying outdoors, and walking/jogging before and during the time they played Pokémon Go, evaluated the physical activity levels of players, ex-players and non-players, and investigated the potential factors which determined their play statuses. METHODS: Students in a university answered an online-questionnaire survey. The IPAQ-short form was incorporated to measure vigorous-intensity activities, moderate-intensity activities and walking. Chi square tests were used to compare frequencies and durations of staying outdoors and walking/jogging, health discomforts and physical activity levels between players, ex-players and non-players. Wilcoxon signed ranks tests were performed to assess the changes prior to and during the time when the players and ex-players played Pokémon Go. Logistic regression analyses were performed to assess factors contributing to playing, quitting or not playing Pokémon Go. RESULTS: 644 university students answered the questionnaire. Compared with the ex-players, the players were significantly more frequent to stay outdoors when playing Pokémon Go (P < 0.001), walk/jog to a location to catch Pokémon, to Pokéstops or Gyms (P < 0.005), as well as walking/jogging to hatch eggs (P < 0.001). Players who never or rarely walked/jogged before spent a mean of 108.19 ± 158.21 min/week to walk/jog in order to play the game which is equivalent to burning 357 kcal/week for a 60-kg person walking a moderate pace. Compared with the non-players, players were more likely to be aged 18-25 years [OR (95% CI) 3.28 (1.28-8.40), P = 0.013], never [OR (95% CI) 10.51 (1.12-98.57), P = 0.039] or rarely [OR (95% CI) 4.00 (1.95-8.23), P < 0.001] stayed outdoors and rarely walked/jogged prior to playing the game [OR (95% CI) 3.88 (1.86-8.05), P < 0.001]. However, there was no significant difference in physical activity levels between the three groups (P = 0.573). CONCLUSIONS: Players who used to be sedentary benefited the most from Pokémon Go. The game can be used as a starting point for sedentary people to begin an active lifestyle. The impact of Pokémon Go on physical activity can provide insights to public health workers in using novel strategies in health promotion.

Framework and components for effective discharge planning system: a Delphi methodology.

BACKGROUND: To reduce avoidable hospital readmissions, effective discharge planning and appropriate post discharge support care are key requirements. This study is a 3-staged process to develop, pretest and pilot a framework for an effective discharge planning system in Hong Kong. This paper reports on the methodology of Delphi approach and findings of the second stage on pre-testing the framework developed so as to validate and attest to its applicability and practicability in which consensus was sought on the key components of discharge planning. METHODS: Delphi methodology was adopted to engage a group of experienced healthcare professionals to rate and discuss the framework and components of an effective discharge planning. The framework was consisted 36 statements under 5 major themes: initial screening, discharge planning process, coordination of discharge, implementation of discharge, and post discharge follow-up. Each statement was rated independently based on 3 aspects including clarity, validity and applicability on a 5-point Likert-scale. Statement with 75% or above of participants scoring 4-5 on all 3 aspects would be included in the discharge planning framework. For those statements not reaching 75% of consensus in any one of the aspect, it would be revised or discarded following the group discussion, and be re-rated in another round. RESULTS: A total of 24 participants participated in the consensus-building process. In round one rating, consensus was achieved in 25 out of 36 statements. Among those 11 statements not reaching consensus, the major concern was related to the "applicability" of the statements. The participants expressed a lack of manpower, skills and time in particular during weekends and long holidays in carrying out assessment and care plans within 24 h after admission. There were also timeliness and availability issue in providing transportation and necessary equipment to the patients. To make the statements more applicable, the wordings of some of the statements were revised to provide greater flexibility. Due to the lack of a statement in clarifying the role of the members of the healthcare professional team, one additional statement on the role and responsibility of the multidisciplinary team members was added. The first theme on "initial screening" was further revised to "initial screening and assessment" to better reflect the first stage of discharge planning process. After two rounds of rating process, all the 36 statements and the newly added statement reached consensus CONCLUSIONS: A structured, systematic and coordinated system of hospital discharge system is required to facilitate the discharge process to ensure a smooth patient transition from the hospital to the community and improve patient health outcome in both clinical and social aspect. The findings of this paper provide a reference framework helping policymakers and hospital managers to facilitate the development of a coherent and systematized discharge planning process. Adopting a Delphi approach also demonstrates the values of the method as a pre-test (before the clinical run) of the components and requirements of a discharge planning system taking into account of the local context and system constraints, which would lead to improvements to its applicability and practicability. To confirm the applicability and practicability of this consensus framework for discharge planning system, the third stage of process of development of the discharge planning framework is to apply and pilot the framework in a hospital setting to evaluate its feasibility, applicability and impact in hospital including satisfaction from both the perspectives of staff and patients.

Utility of a preoperative assessment clinic in a tertiary care hospital.

OBJECTIVES: To assess the utilisation rate of a preoperative assessment clinic and its impact on length of stay and discharge destinations. DESIGN: Retrospective case series with internal comparisons. SETTING: A tertiary hospital in Hong Kong. PATIENTS: All medical records of elective surgical admissions to a hospital in Hong Kong from April to June 2008 were retrieved. Medical records of patients who did not attend the preoperative assessment clinic were further reviewed by surgeons to assess if the patients could have been referred to the clinic. MAIN OUTCOME MEASURES: Total length of stay, preoperative and postoperative length of stay, and the discharge destinations of the patients attending and not attending the clinic were compared. RESULTS. In all, 640 patients underwent elective operations, of whom 22 (3%) patients were seen in the preoperative assessment clinic. In patients who had a major operation, the mean (standard deviation) total length of stays for clinic attenders and non-attenders were: 5.2 (3.6) versus 13.2 (18.8) days (P<0.001). The respective figures for preoperative and postoperative length of stay were: 1.3 (2.3) versus 4.5 (8.9) days (P=0.001), and 3.9 (2.9) versus 8.7 (14.5) days (P<0.001). For patients who had an intermediate operation, the respective mean (standard deviation) length of hospital stays were 2.4 (2.0) versus 7.3 (13.9) days (P=0.002) and the figures for postoperative length of stays were 1.3 (0.5) versus 4.5 (9.3) days (P=0.001). Surgeons had classified 108 (17%) of the cases as possible preoperative assessment clinic users. Among the latter, 71 (66%) had no special reason to stay in the hospital. The discharge destination was not associated with the use of preoperative assessment clinic for patients having major (Chi squared=0.18, P=0.912) or intermediate (Chi squared=0.34, P=0.468) operations. CONCLUSION: Successful implementation of preoperative assessment clinic service requires close collaboration between surgeons, anaesthetists, clinicians, and also the re-engineering of health service delivery.

Public perception on the role of community pharmacists in self-medication and self-care in Hong Kong.

BACKGROUND: The choices for self-medication in Hong Kong are much diversified, including western and Chinese medicines and food supplements. This study was to examine Hong Kong public knowledge, attitudes and behaviours regarding self-medication, self-care and the role of pharmacists in self-care. METHODS: A cross-sectional phone survey was conducted, inviting people aged 18 or older to complete a 37-item questionnaire that was developed based on the Thematic Household surveys in Hong Kong, findings of the health prorfessional focus group discussions on pharmacist-led patient self management and literature. Telephone numbers were randomly selected from residential phone directories. Trained interviewers invited eligible persons to participate using the "last birthday method". Associations of demographic characteristics with knowledge, attitudes and beliefs on self-medication, self-care and role of pharmacists, and spending on over-the-counter (OTC) products were analysed statistically. RESULTS: A total of 1, 560 phone calls were successfully made and 1, 104 respondents completed the survey which indicated a response rate of 70.8%. 63.1% had adequate knowledge on using OTC products. Those who had no formal education/had attended primary education (OR = 3.19, 95%CI 1.78-5.72; p < 0.001), had attended secondary education (OR = 1.50, 95%CI 1.03-2.19; p = 0.035), and aged ≥ 60 years (OR = 1.82, 95% CI 1.02-3.26; p = 0.042) were more likely to have inadequate knowledge on self-medication. People with chronic disease also tended to spend more than HKD100 on western (OR = 3.58, 95%CI 1.58-8.09; p = 0.002) and Chinese OTC products (OR = 2.94, 95%CI 1.08-7.95; p = 0.034). 94.6% believed that patients with chronic illnesses should self-manage their diseases. 68% agreed that they would consult a pharmacist before using OTC product but only 45% agreed that pharmacists could play a leading role in self-care. Most common reasons against pharmacist consultation on self-medication and self-care were uncertainty over the role of pharmacists and low acceptance level of pharmacists. CONCLUSIONS: The majority of respondents supported patients with chronic illness to self-manage their diseases but less than half agreed to use a pharmacist-led approach in self-care. The government should consider developing doctors-pharmacists partnership programs in the community, enhancing the role of pharmacists in primary care and providing education to patients to improve their awareness on the role of pharmacists in self-medication and self-care.

Risk factors of hospitalization and readmission of patients with COPD in Hong Kong population: analysis of hospital admission records.

BACKGROUND: Chronic Obstructive Pulmonary Disease (COPD) accounts for around 4% of all public hospital annual admissions in Hong Kong. By year 2020, COPD will be ranked fifth among the conditions with the highest burden to the society. This study identifies admission and unplanned readmission of COPD patients, factors affecting unplanned readmission, and estimates its cost burden on the public healthcare system in Hong Kong. METHODS: This is a retrospective study analyzing COPD admissions to all public hospitals in Hong Kong. All admission episodes to acute medical wards with the principal diagnosis of COPD (ICD-9:490-492, 494-496) from January 2006 to December 2007 were captured. Unplanned readmission was defined as an admission which followed a previous admission within 30 days. RESULTS: In 2006 and 2007, 65497 (8.0%) of episodes from medical wards were identified as COPD admissions, and among these, 15882 (24.2%) were unplanned readmissions. The mean age of COPD patients was 76.81 ± 9.59 years and 77% were male. Unplanned readmission was significantly associated with male gender, receiving public assistance and living in nursing homes while no association was found with the Charlson comorbidity index. Patients who were readmitted unplanned had a significant longer acute length of stay (ß = 0.3894, P < 0.001) after adjustment for other covariates. CONCLUSIONS: Unplanned readmission of COPD patients has a huge impact on the public healthcare system. A systematic approach in programme provision and a good discharge planning process targeting on COPD patients who are at high risk of unplanned readmission are essential.

The Chinese-version of the CARE measure reliably differentiates between doctors in primary care: a cross-sectional study in Hong Kong.

BACKGROUND: The Consultation and Relational Empathy (CARE) Measure is a widely used patient-rated experience measure which has recently been translated into Chinese and has undergone preliminary qualitative and quantitative validation. The objective of this study was to determine the reliability of the Chinese-version of the CARE Measure in reliably differentiating between doctors in a primary care setting in Hong Kong METHODS: Data were collected from 984 primary care patients attending 20 doctors with differing levels of training in family medicine in 5 public clinics in Hong Kong. The acceptability of the Chinese-CARE measure to patients was assessed. The reliability of the measure in discriminating effectively between doctors was analysed by Generalisability-theory (G-Theory) RESULTS: The items in the Chinese-CARE measure were regarded as important by patients and there were few 'not applicable' responses. The measure showed high internal reliability (coefficient 0.95) and effectively differentiated between doctors with only 15-20 patient ratings per doctor (inter-rater reliability > 0.8). Doctors' mean CARE measure scores varied widely, ranging from 24.1 to 45.9 (maximum possible score 50) with a mean of 34.6. CARE Measure scores were positively correlated with level of training in family medicine (Spearman's rho 0.493, p < 0.05). CONCLUSION: These data demonstrate the acceptability, feasibility and reliability of using the Chinese-CARE Measure in primary care in Hong Kong to differentiate between doctors interpersonal competencies. Training in family medicine appears to enhance these key interpersonal skills.

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.

Unplanned readmission rates, length of hospital stay, mortality, and medical costs of ten common medical conditions: a retrospective analysis of Hong Kong hospital data.

BACKGROUND: Studies on readmissions attributed to particular medical conditions, especially heart failure, have generally not addressed the factors associated with readmissions and the implications for health outcomes and costs. This study aimed to investigate the factors associated with 30-day unplanned readmission for 10 common conditions and to determine the cost implications. METHODS: This population-based retrospective cohort study included patients admitted to all public hospitals in Hong Kong in 2007. The sample consisted of 337,694 hospitalizations in Internal Medicine. The disease-specific risk-adjusted odd ratio (OR), length of stay (LOS), mortality and attributable medical costs for the year were examined for unplanned readmissions for 10 medical conditions, namely malignant neoplasms, heart diseases, cerebrovascular diseases, pneumonia, injury and poisoning, nephritis and nephrosis, diabetes mellitus, chronic liver disease and cirrhosis, septicaemia, and aortic aneurysm. RESULTS: The overall unplanned readmission rate was 16.7%. Chronic liver disease and cirrhosis had the highest OR (1.62, 95% confidence interval (CI) 1.39-1.87). Patients with cerebrovascular disease had the longest LOS, with mean acute and rehabilitation stays of 6.9 and 3.0 days, respectively. Malignant neoplasms had the highest mortality rate (30.8%) followed by aortic aneurysm and pneumonia. The attributed medical cost of readmission was highest for heart disease (US$3 199 418, 95% CI US$2 579 443-803 393). CONCLUSIONS: Our findings showed variations in readmission rates and mortality for different medical conditions which may suggest differences in the quality of care provided for various medical conditions. In-hospital care, comprehensive discharge planning, and post-discharge community support for patients need to be reviewed to improve the quality of care and patient health outcomes.

Patient self-management and pharmacist-led patient self-management in Hong Kong: a focus group study from different healthcare professionals' perspectives.

BACKGROUND: Patient self-management is a key approach to manage non-communicable diseases. A pharmacist-led approach in patient self-management means collaborative care between pharmacists and patients. However, the development of both patient self-management and role of pharmacists is limited in Hong Kong. The objectives of this study are to understand the perspectives of physicians, pharmacists, traditional Chinese medicine (TCM) practitioners, and dispensers on self-management of patients with chronic conditions, in addition to exploring the possibilities of developing pharmacist-led patient self-management in Hong Kong. METHODS: Participants were invited through the University as well as professional networks. Fifty-one participants comprised of physicians, pharmacists, TCM practitioners and dispensers participated in homogenous focus group discussions. Perspectives in patient self-management and pharmacist-led patient self-management were discussed. The discussions were audio recorded, transcribed and analysed accordingly. RESULTS: The majority of the participants were in support of patients with stable chronic diseases engaging in self-management. Medication compliance, monitoring of disease parameters and complications, lifestyle modification and identifying situations to seek help from health professionals were generally agreed to be covered in patient self-management. All pharmacists believed that they had extended roles in addition to drug management but the other three professionals believed that pharmacists were drug experts only and could only play an assisting role. Physicians, TCM practitioners, and dispensers were concerned that pharmacist-led patient self-management could be hindered, due to unfamiliarity with the pharmacy profession, the perception of insufficient training in disease management, and lack of trust of patients. CONCLUSIONS: An effective chronic disease management model should involve patients in stable condition to participate in self-management in order to prevent health deterioration and to save healthcare costs. The role of pharmacists should not be limited to drugs and should be extended in the primary healthcare system. Pharmacist-led patient self-management could be developed gradually with the support of government by enhancing pharmacists' responsibilities in health services and developing public-private partnership with community pharmacists. Developing facilitating measures to enhance the implementation of the pharmacist-led approach should also be considered, such as allowing pharmacists to access electronic health records, as well as deregulation of more prescription-only medicines to pharmacy-only medicines.

Perspective from health professionals on delivery of sub-acute care in Hong Kong: a qualitative study in a health system.

OBJECTIVES: The perception and understanding of health professionals of the role of sub-acute care in the health system will have an impact on the potential effectiveness in preventing unnecessary hospitalization. This study aims to explore the perceived role and quality of sub-acute care services in the context of Hong Kong from the perspective of health service providers and to identify barriers to effectiveness. METHODS: Seven focus groups were conducted and the discussion was led by a guide covering three main areas: definition/component/role of sub-acute, difficulties in the sub-acute care services provision, and suggestion for further improvement in the provision of sub-acute care. RESULTS: The participants highlighted the positive role of sub-acute to promote patient's health and quality of life so as to reduce unnecessary hospitalization. The potential barriers in the sub-acute care identified were interrelated and focused mainly on systemic issues including lack of service coordination, specialist input and resources. The participants also suggested a number of practical ways to improve the quality of sub-acute care services. CONCLUSIONS: The findings showed a need for further improvement in the process of sub-acute care by developing operation guideline and re-evaluating the allocation of resources to support the sub-acute care provision.

Transition care for adolescents and families with chronic illnesses.

OBJECTIVES: To explore the attitudes of adolescents and parents toward transition care and to identify factors and barriers associated with transition decision. METHODS: The study was conducted at a pediatric out-patient clinic using a self-administered questionnaire to evaluate the perspective of adolescent chronic patients on transition care for common chronic diseases. Despite its importance as emphasized in medical literature, transition care for adolescent patients with chronic illnesses is under-developed in Hong Kong. RESULTS: A total of 137 adolescents aged 16-19 years, and 67 parents completed the survey; 85.3% of adolescents and 82.5% of parents were willing to transfer to adult care. "Adolescent's perception of his/her own responsibility towards chronic illness" was positively associated with willingness to transfer to adult care (OR = 3.84; 95% CI, 1.41-10.45; p = .008), whereas "Detailed explanation by doctors" encouraged transition decision for adolescents (OR = 12.20; 95% CI, 1.22-122.33; p = .033). "Do not want to change" was the only significant barrier for transition for both adolescents (OR = .08; 95% CI, .01-.50; p = .007) and parents (OR = .07; 95% CI, .02-.36; p = .001). However, less than 10% of subjects had ever received any transition information from doctors or other healthcare workers. CONCLUSIONS: This is the first study in Asia region evaluating attitudes of adolescents and parents on transition care. The majority of adolescents and parents accept transition care from pediatrics to adult service, but only a small proportion has ever received transition information from doctors. Our findings should be useful to healthcare providers in planning transition care programmes for adolescent patients with chronic illnesses.

Avoidable readmission in Hong Kong--system, clinician, patient or social factor?

BACKGROUND: Studies that identify reasons for readmissions are gaining importance in the light of the changing demographics worldwide which has led to greater demand for hospital beds. It is essential to profile the prevalence of avoidable readmissions and understand its drivers so as to develop possible interventions for reducing readmissions that are preventable. The aim of this study is to identify the magnitude of avoidable readmissions, its contributing factors and costs in Hong Kong. METHODS: This was a retrospective analysis of 332,453 inpatient admissions in the Medical specialty in public hospital system in Hong Kong in year 2007. A stratified random sample of patients with unplanned readmission within 30 days after discharge was selected for medical record reviews. Eight physicians reviewed patients' medical records and classified whether a readmission was avoidable according to an assessment checklist. The results were correlated with hospital inpatient data. RESULTS: It was found that 40.8% of the 603 unplanned readmissions were judged avoidable by the reviewers. Avoidable readmissions were due to: clinician factor (42.3%) including low threshold for admission and premature discharge etc.; patient factor (including medical and health factor) (41.9%) such as relapse or progress of previous complaint, and compliance problems etc., followed by system factor (14.6%) including inadequate discharge planning, inadequate palliative care/terminal care, etc., and social factor (1.2%) such as carer system, lack of support and community services. After adjusting for patients' age, gender, principal diagnosis at previous discharge and readmission hospitals, the risk factors for avoidable readmissions in the total population i.e. all acute care admissions irrespective of whether there was a readmission or not, included patients with a longer length of stay, and with higher number of hospitalizations and attendance in public outpatient clinics and Accident and Emergency departments in the past 12 months. In the analysis of only unplanned readmissions, it was found that the concordance of the principal diagnosis for admission and readmission, and shorter time period between discharge and readmission were associated with avoidable readmissions. CONCLUSIONS: Our study found that almost half of the readmissions could have been prevented. They had been mainly due to clinician and patient factors, in particular, both of which were intimately related to clinical management and patient care. These readmissions could be prevented by a system of ongoing clinical review to examine the clinical practice/decision for discharge, and improving clinical care and enhancing patient knowledge of the early warning signs for relapse. The importance of adequate and appropriate ambulatory care to support the patients in the community was also a key finding to reduce avoidable readmissions. Education on patient self-management should also be enhanced to minimize the patient factors with regard to avoidable readmission. Our findings thus provide important insights into the development of an effective discharge planning system which should place patients and carers as the primacy focus of care by engaging them along with the healthcare professionals in the whole discharge planning process.

Measuring and preventing potentially avoidable hospital readmissions: a review of the literature.

OBJECTIVE: To review literature identifying key components for measuring avoidable readmissions, their prevalence, risk factors, and interventions that can reduce potentially avoidable readmissions. DATA SOURCES AND EXTRACTION: Literature search using Medline, PubMed and the Cochrane Library up to June 2010, using the terms "avoidable", "preventable", "unplanned", "unnecessary", "readmission", and "rehospitalization". STUDY SELECTION: A total of 48 original papers and review articles were selected for inclusion in this review. DATA SYNTHESIS: Although hospital readmission seemed to be a term commonly used as an outcome indicator in many studies, it is difficult to make valid comparison of results from different studies. This is because the definitions of terms, methods of data collection, and approaches to data analysis differ greatly. The following criteria for studying hospital readmissions have been recommended: (a) identify hospital admissions and define relevant terms, (b) establish a clinical diagnosis for a readmission; (c) establish the purpose for a readmission, (d) set a discharge-to-readmission timeframe, and (e) identify the sources of information for assessing readmissions. Studies to identify avoidable readmissions usually involve medical records and chart reviews by clinicians using the classification scheme developed by the authors. The proportion of all readmissions assessed as preventable varies from 9 to 59% depending on the population of patients studied, duration of follow-up, type and methodology of the study and case-mix-related factors. A number of studies classified risk factors for readmission into four categories: patient, social, clinical, and system factors. Home-based interventions, intensive education/counselling, multidisciplinary care approaches, and telephone follow-up were the main types of interventions to address potentially avoidable readmissions. CONCLUSIONS: A standard instrument to identify avoidable readmission is important in enabling valid comparisons within the system and at different timelines, so as to permit robust evaluation of interventions. The assessment of preventable risk factors for readmissions also provides a basis for designing and implementing intervention programmes.
