Preoperative Rehabilitation Is Feasible in the Weeks Prior to Surgery and Significantly Improves Functional Performance.

BACKGROUND: Frailty is a multidimensional state of increased vulnerability. Frail patients are at increased risk for poor surgical outcomes. Prior research demonstrates that rehabilitation strategies deployed after surgery improve outcomes by building strength. OBJECTIVES: Examine the feasibility and impact of a novel, multi-faceted prehabilitation intervention for frail patients before surgery. DESIGN: Single arm clinical trial. SETTING: Veterans Affairs hospital. PARTICIPANTS: Patients preparing for major abdominal, urological, thoracic, or cardiac surgery with frailty identified as a Risk Analysis Index≥30. INTERVENTION: Prehabilitation started in a supervised setting to establish safety and then transitioned to home-based exercise with weekly telephone coaching by exercise physiologists. Prehabilitation included (a)strength and coordination training; (b)respiratory muscle training (IMT); (c)aerobic conditioning; and (d)nutritional coaching and supplementation. Prehabilitation length was tailored to the 4-6 week time lag typically preceding each participant's normally scheduled surgery. MEASUREMENTS: Functional performance and patient surveys were assessed at baseline, every other week during prehabilitation, and then 30 and 90 days after surgery. Within-person changes were estimated using linear mixed models. RESULTS: 43 patients completed baseline assessments; 36(84%) completed a median 5(range 3-10) weeks of prehabilitation before surgery; 32(74%) were retained through 90-day follow-up. Baseline function was relatively low. Exercise logs show participants completed 94% of supervised exercise, 78% of prescribed IMT and 74% of home-based exercise. Between baseline and day of surgery, timed-up-and-go decreased 2.3 seconds, gait speed increased 0.1 meters/second, six-minute walk test increased 41.7 meters, and the time to complete 5 chair rises decreased 1.6 seconds(all P≤0.007). Maximum and mean inspiratory and expiratory pressures increased 4.5, 7.3, 14.1 and 13.5 centimeters of water, respectively(all P≤0.041). CONCLUSIONS: Prehabilitation is feasible before major surgery and achieves clinically meaningful improvements in functional performance that may impact postoperative outcomes and recovery. These data support rationale for a larger trial powered to detect differences in postoperative outcomes.

The impact of cigarette smoking on life expectancy between 1980 and 2010: a global perspective.

INTRODUCTION: Tobacco smoking is among the leading causes of preventable mortality worldwide. We assessed the impact of smoking on life expectancy worldwide between 1980 and 2010. METHODS: We retrieved cause-specific mortality data from the WHO Mortality Database by sex, year and age for 63 countries with high or moderate quality data (1980-2010). Using the time of the peak of the smoking epidemic by country, relative risks from the three waves of the Cancer Prevention Study were applied to calculate the smoking impact ratio and population attributable fraction. Finally, we estimated the potential gain in life expectancy at age 40 if smoking-related deaths in middle age (40-79 years) were eliminated. RESULTS: Currently, tobacco smoking is related to approximately 20% of total adult mortality in the countries in this study (24% in men and 12% in women). If smoking-related deaths were eliminated, adult life expectancy would increase on average by 2.4 years in men (0.1 in Uzbekistan to 4.8 years in Hungary) and 1 year in women (0.1 in Kyrgyzstan to 2.9 years in the USA). The proportion of smoking-related mortality among men has declined in most countries, but has increased in the most populous country in the world, that is, China from 4.6% to 7.3%. Increases in the impact of tobacco on life expectancy were observed among women in high-income countries. CONCLUSIONS: Recent trends indicate a substantial rise in the population-level impact of tobacco smoking on life expectancy in women and in middle-income countries. High-quality local data are needed in most low-income countries.

Childhood cancer incidence in South Africa, 1987-2007.

BACKGROUND: Childhood cancer is an emerging problem in Africa. Its extent is hazy because data are scarce, but it should be addressed. This is the first report from the South African Children's Tumour Registry (SACTR), which covers the whole of South Africa (SA). It provides minimal estimates of cancer incidence and discusses the challenges of cancer surveillance and control in a child population in a middle-income country. Only about 2% of the African population is covered by cancer registries producing comparable incidence data. OBJECTIVE: To present and interpret incidence patterns and trends of childhood cancer over a 21-year period. The results should raise awareness of the problem of childhood cancer in an African population and provide sensible data for taking this problem in hand. METHODS: All eligible and validated cancer cases registered in the SACTR over the period 1987-2007 and classified according to the International Classification of Childhood Cancer were included. Population data were retrieved from official sources and estimated for the population subcategories. Incidence rates were standardised to the world standard and time trends were evaluated using joinpoint models, adjusting for sex and age. RESULTS: Based on the 11,699 cases, the overall age-standardised average annual incidence rate was 45 per million. Threefold differences in the overall incidence rates were observed between the ethnic groups, ranging from 116 for whites to 37 for black Africans, and they differed by diagnostic group. Differences between the nine provinces of SA relate to the ethnic composition and prevailing socioeconomic status. The overall incidence rate declined by 1.2% per year for the whole country (p<0.01). However, the decline was mainly observed during the first few years of the study period, after which rates stabilised or increased. CONCLUSIONS: Diagnosis and notification of childhood cancer should improve. The differences in incidence between ethnic groups suggest the priorities for cancer control.

Cancer Incidence in Five Continents: Inclusion criteria, highlights from Volume X and the global status of cancer registration.

Cancer Incidence in Five Continents (CI5), a longstanding collaboration between the International Agency for Research on Cancer and the International Association of Cancer Registries, serves as a unique source of cancer incidence data from high-quality population-based cancer registries around the world. The recent publication of Volume X comprises cancer incidence data from 290 registries covering 424 populations in 68 countries for the registration period 2003-2007. In this article, we assess the status of population-based cancer registries worldwide, describe the techniques used in CI5 to evaluate their quality and highlight the notable variation in the incidence rates of selected cancers contained within Volume X of CI5. We also discuss the Global Initiative for Cancer Registry Development as an international partnership that aims to reduce the disparities in availability of cancer incidence data for cancer control action, particularly in economically transitioning countries, already experiencing a rapid rise in the number of cancer patients annually.

Increased prevalence and geographic spread of the cardiopulmonary nematode Angiostrongylus vasorum in fox populations in Great Britain.

The nematode Angiostrongylus vasorum is becoming more widely recorded globally, and is of increasing concern as a cause of disease in dogs. Apparent geographic spread is difficult to confirm due to a lack of standardized disease recording systems, increasing awareness among veterinary clinicians, and recent improvements in diagnostic technologies. This study examines the hypothesis that A. vasorum has spread in recent years by repeating the methods of a previous survey of the fox population. The hearts and lungs of 442 foxes from across Great Britain were collected and examined by dissection and flushing of the pulmonary circulation and microscopic inspection of tracheal scrapes. Sampling and parasite extraction methods were identical to an earlier survey in 2005 to ensure comparability. Prevalence of A. vasorum was 18·3% (exact binomial confidence bounds 14·9-22·3), compared with 7·3% previously (5·3-9·9, n = 546), and had increased significantly in most regions, e.g. 7·4% in the Northern UK (previously zero) and 50·8% in the south-east (previously 23·2%). Other nematodes identified were Crenosoma vulpis (prevalence 10·8%, CI 8·1-14·2) and Eucoleus aerophilus (31·6%, CI 27·3-36·2). These data support the proposal that A. vasorum has increased in prevalence and has spread geographically in Great Britain.

Global patterns of cardia and non-cardia gastric cancer incidence in 2012.

OBJECTIVE: Globally, gastric cancer incidence shows remarkable international variation and demonstrates distinct characteristics by the two major topographical subsites, cardia (CGC) and non-cardia (NCGC). Because global incidence estimates by subsite are lacking, we aimed to describe the worldwide incidence patterns of CGC and NCGC separately. DESIGN: Using Cancer Incidence in Five Continents Volume X (CI5X), we ascertained the proportions of CGC and NCGC by country, sex and age group (<65 and ≥65 years). These derived proportions were applied to GLOBOCAN 2012 data to estimate country-specific age-standardised CGC and NCGC incidence rates (ASR). Regional proportions were used to estimate rates for countries not included in CI5X. RESULTS: According to our estimates, in 2012, there were 260,000 cases of CGC (ASR 3.3 per 100,000) and 691,000 cases of NCGC (ASR 8.8) worldwide. The highest regional rates of both gastric cancer subsites were in Eastern/Southeastern Asia (in men, ASRs: 8.7 and 21.7 for CGC and NCGC, respectively). In most countries NCGC occurred more frequently than CGC with an average ratio of 2:1; however, in some populations where NCGC incidence rates were lower than the global average, CGC rates were similar or higher than NCGC rates. Men had higher rates than women for both subsites but particularly for CGC (male-to-female ratio 3:1). CONCLUSIONS: This study has, for the first time, quantified global incidence patterns of CGC and NCGC providing new insights into the global burden of these cancers. Country-specific estimates are provided; however, these should be interpreted with caution. This work will support future investigations across populations.

Silver spoons in the rough: can environmental enrichment improve survival of hatchery Atlantic salmon Salmo salar in the wild?

This study tested the 'silver spoon' hypothesis which posits that individuals that develop under favourable conditions should enjoy a fitness advantage later in life because they are more likely to recognize and settle in high-quality habitats. Atlantic salmon Salmo salar of two age classes (0+ and 1+ years) were reared in environmentally enriched or standard hatchery tanks for a short period (c. 10 weeks), were then released into a natural river and sampled on repeated occasions to test for silver-spoon effects. Compared with controls, enriched fish had a 6.4% higher recapture rate and settled in higher velocity habitats when they were stocked as 0+ year fry, but not when they were stocked as 1+ year parr. The opportunity for selection was generally higher for environmentally enriched fish than for controls, and also higher for 0+ than for 1+ year fish. Selection favoured individuals with high condition factor, extensive fat reserves and longer than average pectoral fins in both age classes but favoured a small body size in 1+ year and a large body size in 0+ year releases. Stomach analysis showed that enriched fish ate more, and adapted quicker to natural prey than controls. These results provide support for silver-spoon effects in fish and indicate that enrichment can improve post-release performance in conservation programmes, but seemingly only if fish are not kept in captivity for too long.

The influence of geographical access to health care and material deprivation on colorectal cancer survival: evidence from France and England.

This article investigates the influence of distance to health care and material deprivation on cancer survival for patients diagnosed with a colorectal cancer between 1997 and 2004 in France and England. This population-based study included all cases of colorectal cancer diagnosed between 1997 and 2004 in 3 cancer registries in France and 1 cancer registry in England (N=40,613). After adjustment for material deprivation, travel times in England were no longer significantly associated with survival. In France patients living between 20 and 90min from the nearest cancer unit tended to have a poorer survival, although this was not statistically significant. In England, the better prognosis observed for remote patients can be explained by associations with material deprivation; distance to health services alone did not affect survival whilst material deprivation level had a major influence, with lower survival for patients living in deprived areas. Increases in travel times to health services in France were associated with poorer survival rates. The pattern of this influence seems to follow an inverse U distribution, i.e. maximal for average travel times.

An exploration of reported mortality from cutaneous squamous cell carcinoma using death certification and cancer registry data.

BACKGROUND: Cutaneous squamous cell carcinoma (cSCC) is increasing in incidence but mortality rates are low. Identifying high-risk tumours is important when rationalizing clinical review for patients with cSCC. OBJECTIVES: To assess the accuracy of death certification in cases of reported fatal cSCC and to identify risk factors for fatal cSCC. METHODS: A retrospective, observational study of cases of fatal cSCC over 11 years (1993-2004) in Leeds, identified in cancer registry and death certification data. RESULTS: Fifty-eight patients were recorded by the registry as having fatal cSCC in this period. Review of case notes and pathology specimens, where available (34 cases), confirmed that 21/34 patients had died of cSCC. Five were on the ear and none on the lip. Four patients had been treated for leukaemia or lymphoma and one was a renal transplant recipient. On pathology review five patients proved to have had malignant adnexal tumours rather than cSCC, and one a melanoma. In addition, three patients had disease of the ear canal or vulva. CONCLUSIONS: A proportion of deaths were falsely attributed to cSCC as a result of inaccurate histological diagnosis. Some fatalities were related to tumours in sites known to be at higher risk, and a significant proportion was postulated to be related to immunosuppression. In those cases attributed to cSCC in which this could be assessed, the majority were American Joint Committee on Cancer stage 2 and only 24% were in high-risk sites.

Cancer incidence and mortality patterns in Europe: estimates for 40 countries in 2012.

INTRODUCTION: Cancer incidence and mortality estimates for 25 cancers are presented for the 40 countries in the four United Nations-defined areas of Europe and for the European Union (EU-27) for 2012. METHODS: We used statistical models to estimate national incidence and mortality rates in 2012 from recently-published data, predicting incidence and mortality rates for the year 2012 from recent trends, wherever possible. The estimated rates in 2012 were applied to the corresponding population estimates to obtain the estimated numbers of new cancer cases and deaths in Europe in 2012. RESULTS: There were an estimated 3.45 million new cases of cancer (excluding non-melanoma skin cancer) and 1.75 million deaths from cancer in Europe in 2012. The most common cancer sites were cancers of the female breast (464,000 cases), followed by colorectal (447,000), prostate (417,000) and lung (410,000). These four cancers represent half of the overall burden of cancer in Europe. The most common causes of death from cancer were cancers of the lung (353,000 deaths), colorectal (215,000), breast (131,000) and stomach (107,000). In the European Union, the estimated numbers of new cases of cancer were approximately 1.4 million in males and 1.2 million in females, and around 707,000 men and 555,000 women died from cancer in the same year. CONCLUSION: These up-to-date estimates of the cancer burden in Europe alongside the description of the varying distribution of common cancers at both the regional and country level provide a basis for establishing priorities to cancer control actions in Europe. The important role of cancer registries in disease surveillance and in planning and evaluating national cancer plans is becoming increasingly recognised, but needs to be further advocated. The estimates and software tools for further analysis (EUCAN 2012) are available online as part of the European Cancer Observatory (ECO) (http://eco.iarc.fr).

Management of colorectal cancer explains differences in 1-year relative survival between France and England for patients diagnosed 1997-2004.

BACKGROUND: Few international population-based studies have provided information on potential determinants of international disparities in cancer survival. This population-based study was undertaken to identify the principal differences in disease characteristics and management that accounted for previously observed poorer survival in English compared with French patients with colorectal cancer. METHODS: The study population comprised all cases of colorectal cancer diagnosed between 1997 and 2004 in the areas covered by three population-based cancer registries in France and one in England (N=40 613). To investigate the influence of clinical and treatment variables on survival, we applied multivariable excess hazard modelling based on generalised linear models with Poisson error. RESULTS: Poorer survival for English patients was primarily due to a larger proportion dying within the first year after diagnosis. After controlling for inter-country differences in the use of chemotherapy and surgical resection with curative intent, country of residence was no-longer associated with 1-year survival for advanced colon cancer patients (excess hazard ratio (EHR)=0.99 (0.92-1.01), P=0.095)). Longer term (2-5 years) excess hazards of death for colon and rectal cancer patients did not differ between France and England. CONCLUSION: This study suggests that difference in management close to diagnosis of colon and rectum cancer is related to differences in survival observed between France and England. All efforts (collection and standardisation of additional variables such as co-morbidity) to investigate the reasons for these disparities in management between these two countries, and more generally across Europe, should be encouraged.

Population-based study of laparoscopic colorectal cancer surgery 2006-2008.

BACKGROUND: Clinical guidelines recommend that, where clinically appropriate, laparoscopic tumour resections should be available for patients with colorectal cancer. This study aimed to examine the introduction of laparoscopic surgery in the English National Health Service. METHODS: Data were extracted from the National Cancer Data Repository on all patients who underwent major resection for a primary colorectal cancer diagnosed between 2006 and 2008. Laparoscopic procedures were identified from codes in the Hospital Episode Statistics and National Bowel Cancer Audit Project data in the resource. Trends in the use of laparoscopic surgery and its influence on outcomes were examined. RESULTS: Of 58 135 resections undertaken over the study period, 10 955 (18·8 per cent) were attempted laparoscopically. This increased from 10·0 (95 per cent confidence interval (c.i.) 8·1 to 12·0) per cent in 2006 to 28·4 (25·4 to 31·4) per cent in 2008. Laparoscopic surgery was used less in patients with advanced disease (modified Dukes' stage 'D' versus A: odds ratio (OR) 0·45, 95 per cent c.i. 0·40 to 0·50), rectal tumours (OR 0·71, 0·67 to 0·75), those with more co-morbidity (Charlson score 3 or more versus 0: OR 0·69, 0·58 to 0·82) or presenting as an emergency (OR 0·15, 0·13 to 0·17). A total of 1652 laparoscopic procedures (15·1 per cent) were converted to open surgery. Conversion was more likely in advanced disease (modified Dukes' stage 'D' versus A: OR 1·56, 1·20 to 2·03), rectal tumours (OR 1·29, 1·14 to 1·46) and emergencies (OR 2·06, 1·54 to 2·76). Length of hospital stay (OR 0·65, 0·64 to 0·66), 30-day postoperative mortality (OR 0·55, 0·48 to 0·64) and risk of death within 1 year (hazard ratio 0·60, 0·55 to 0·65) were reduced in the laparoscopic group. CONCLUSION: Laparoscopic surgery was used more frequently in low-risk patients.

The natural history of gastro-oesophageal reflux symptoms in the community and its effects on survival: a longitudinal 10-year follow-up study.

BACKGROUND: Gastro-oesophageal reflux symptoms (GERS) are common in the community. However, few studies have examined their long-term natural history, or impact on survival. AIM: To examine these issues in individuals recruited into a community-based screening programme for Helicobacter pylori in 1994. METHODS: Data on mortality and cause of death at 10 years were obtained from the Office for National Statistics. Baseline demographic data, lifestyle factors, gastrointestinal symptoms and quality of life were recorded at study entry. The effect of all these factors on persistent and new-onset GERS, and 10-year mortality, were examined using univariate and multivariate analysis, with results expressed as odds ratios (ORs) or hazard ratios (HR) with 99% confidence intervals (CI). RESULTS: Of 3967 individuals providing complete GERS data at baseline and 10 years, 549 (13.8%) had GERS at baseline. Of these, 183 (33.3%) had persistent symptoms. Among 3418 individuals asymptomatic at baseline, approximately 0.8% per year developed new-onset GERS. No predictors of persistent GERS were identified. New-onset symptoms were associated with lower quality of life or presence of irritable bowel syndrome (IBS) at baseline, and higher body mass index (BMI) at 10 years. There were 8331 (99.1%) of 8407 subjects providing complete GERS data at baseline, 1289 (15.5%) of whom were symptomatic. Presence of GERS at baseline did not affect survival (HR: 0.84; 99% CI: 0.44-1.59). CONCLUSIONS: Gastro-oesophageal reflux symptoms persisted in one-third of individuals, whilst new-onset gastro-oesophageal reflux symptoms were associated with poor quality of life, irritable bowel syndrome and higher body mass index. Gastro-oesophageal reflux symptoms did not impact adversely on survival.

Are lower rates of surgery amongst older women with breast cancer in the UK explained by co-morbidity?

BACKGROUND: Around 60% of women ≥ 80 years old, in the UK do not have surgery for their breast cancer (vs<10% of younger age groups). The extent to which this difference can be accounted for by co-morbidity has not been established. METHODS: A Cancer Registry/Hospital Episode Statistics-linked data set identified women aged ≥ 65 years diagnosed with invasive breast cancer (between 1 April 1997 and 31 March 2005) in two regions of the UK (n=23038). Receipt of surgery by age was investigated using logistic regression, adjusting for co-morbidity and other patient, tumour and treatment factors. RESULTS: Overall, 72% of older women received surgery, varying from 86% of 65-69-year olds to 34% of women aged ≥ 85 years. The proportion receiving surgery fell with increasing co-morbidity (Charlson score 0=73%, score 1=66%, score 2+=49%). However, after adjustment for co-morbidity, older age still predicts lack of surgery. Compared with 65-69-year olds, the odds of surgery decreased from 0.74 (95% CI: 0.66-0.83) for 70-74-year olds to 0.13 (95% CI: 0.11-0.14) for women aged ≥ 85 years. CONCLUSION: Although co-morbidity is associated with a reduced likelihood of surgery, it does not explain the shortfall in surgery amongst older women in the UK. Routine data on co-morbidity enables fairer comparison of treatment across population groups but needs to be more complete.

Developing a useful, user-friendly website for cancer patient follow-up: users' perspectives on ease of access and usefulness.

UK cancer survival has improved, leading to an increase in review patients and pressure on clinics. Use of the Internet for information exchange between patients and healthcare staff may provide a useful adjunct or alternative to traditional follow-up. This study aimed to develop and evaluate a website for use in follow-up cancer care in terms of usability, feasibility and acceptability. A website was developed and underwent iterative amendment following patient usability testing in focus groups. Patients on follow-up completed a Computer and Internet Usage Questionnaire. Internet users consented to a randomised crossover study to complete paper and online questionnaires, browse the website and participate in a website evaluation interview. Patient website use was tracked. Usability: Website changes were made following patient testing (n= 21). Patients would have liked a 'personalized' website with links to their clinical team, out with the scope of this study. Feasibility: The majority of participants (65%) had Internet access. Age remained a differentiating factor. Acceptability: Final evaluation (n= 103) was positive although many would like to maintain face-to-face hospital contact. User involvement in website design can ensure patient needs are met. A website model for follow-up will suit some patients but others will prefer clinical contact.

Cancer survivors' experiences of discharge from hospital follow-up.

Discharge from hospital follow-up is a key time point in the cancer journey. With recommendations for earlier discharge of cancer survivors, attention to the discharge process is likely to become increasingly important. This study explored cancer survivors' experiences of discharge from hospital follow-up. Survivors of breast, colorectal and prostate cancer (n= 1275), 5-16 years post diagnosis were approached to take part in a questionnaire survey. The questionnaire included questions about discharge status, provision of time/information prior to discharge, feelings at discharge and satisfaction with how discharge was managed. Completed questionnaires were returned by 659 survivors (51.7%). Approximately one-third of respondents were not discharged from follow-up 5-16 years post diagnosis. Of those discharged, a substantial minority reported insufficient time (27.9%), information (24.5-45.0%) or adverse emotions (30.9%) at the time of discharge. However, 90.6% of respondents reported satisfaction with how discharge from hospital follow-up was managed. Despite high levels of satisfaction, discharge of cancer survivors from hospital follow-up could be improved with the provision of additional time, information and support. Better structuring of the final hospital appointment or a review appointment in primary care at this time could help to ensure that discharge from hospital follow-up is managed optimally for cancer survivors.

Long-term health outcomes in a British cohort of breast, colorectal and prostate cancer survivors: a database study.

BACKGROUND: The community-based incidence of cancer treatment-related long-term consequences is uncertain. We sought to establish the burden of health outcomes that have been associated with treatment among British long-term cancer survivors. METHODS: We identified 26,213 adults from the General Practice Research Database who have survived 5 years or more following breast, colorectal or prostate cancer. Four age-, sex- and general practice-matched non-cancer controls were selected for each survivor. We considered the incidence of treatment-associated health outcomes using Cox proportional hazards models. RESULTS: Breast cancer survivors had an elevated incidence of heart failure (hazards ratio (HR) 1.95, 95% confidence interval (CI) 1.27-3.01), coronary artery disease (HR 1.27, 95% CI 1.11-1.44), hypothyroidism (HR 1.26, 95% CI 1.02-1.56) and osteoporosis (HR 1.26, 95% CI 1.13-1.40). Among colorectal cancer survivors, there was increased incidence of dementia (HR 1.68, 95% CI 1.20-2.35), diabetes (HR 1.39, 95% CI 1.12-1.72) and osteoporosis (HR 1.41, 95% CI 1.15-1.73). Prostate cancer survivors had the highest risk of osteoporosis (HR 2.49, 95% CI 1.93-3.22). CONCLUSIONS: The study confirms the occurrence of increased incidence of chronic illnesses in long-term cancer survivors attributable to underlying lifestyle and/or cancer treatments. Although the absolute risk of the majority of late effects in the cancer survivors cohort is low, identifying prior risk of osteoporosis by bone mineral density scanning for prostate survivors should be considered. There is an urgent need to improve primary care recording of cancer treatment.

Integrating cancer survivors' experiences into UK cancer registries: design and development of the ePOCS system (electronic Patient-reported Outcomes from Cancer Survivors).

BACKGROUND: Understanding the psychosocial challenges of cancer survivorship, and identifying which patients experience ongoing difficulties, is a key priority. The ePOCS (electronic patient-reported outcomes from cancer survivors) project aims to develop and evaluate a cost-efficient, UK-scalable electronic system for collecting patient-reported outcome measures (PROMs), at regular post-diagnostic timepoints, and linking these with clinical data in cancer registries. METHODS: A multidisciplinary team developed the system using agile methods. Design entailed process mapping the system's constituent parts, data flows and involved human activities, and undertaking usability testing. Informatics specialists built new technical components, including a web-based questionnaire tool and tracking database, and established component-connecting data flows. Development challenges were overcome, including patient usability and data linkage and security. RESULTS: We have developed a system in which PROMs are completed online, using a secure questionnaire administration tool, accessed via a public-facing website, and the responses are linked and stored with clinical registry data. Patient monitoring and communications are semiautomated via a tracker database, and patient correspondence is primarily Email-based. The system is currently honed for clinician-led hospital-based patient recruitment. CONCLUSIONS: A feasibility test study is underway. Although there are possible challenges to sustaining and scaling up ePOCS, the system has potential to support UK epidemiological PROMs collection and clinical data linkage.
