“…For example, a leg ulcer point prevalence of 0.44 per 1000 is within the range 0.39-4.8 per 1000 reported by others. 45,50 However, our pressure ulcer point prevalence estimate (0.31 per 1000) was lower than previous estimates from studies using a geographically defined population. Previous estimates of pressure ulcer prevalence have ranged from 0.4 to 230 per 1000 depending on the baseline risk in the survey population; for example, rates in spinal injury patients are particularly high.…”

“…50 Walker et al 50 conducted a population-based, cross-sectional study in New Zealand in 1998 in which people with leg ulcers were identified by both health-care professionals and self-notification. The team used both traditional and capture-recapture methods to estimate the cumulative incidence and prevalence of leg ulcers.…”

BackgroundComplex wounds are those that heal by secondary intention and include lower-limb ulcers, pressure ulcers and some surgical wounds. The care of people with complex wounds is costly, with care mainly being delivered by community nurses. There is a lack of current, high-quality data regarding the numbers and types of people affected, care received and outcomes achieved.ObjectivesTo (1) assess how high-quality data about complex wounds can be captured effectively for use in both service planning and research while ensuring integration with current clinical data collection systems and minimal impact on staff time; (2) investigate whether or not a clinical register of people with complex wounds could give valid estimates of treatment effects, thus reducing dependence on large-scale randomised controlled trials (RCTs); (3) identify the most important research questions and outcomes for people with complex wounds from the perspectives of patients, carers and health-care professionals; (4) evaluate the potential contributions to decision-making of individual patient data meta-analysis and mixed treatment comparison meta-analysis; and (5) complete and update systematic reviews in topic areas of high priority.MethodsTo meet objectives 1 and 2 we conducted a prevalence survey and developed and piloted a longitudinal disease register. A consultative, deliberative method and in-depth interviews were undertaken to address objective 3. To address objectives 4 and 5 we conducted systematic reviews including mixed treatment comparison meta-analysis.ResultsFrom the prevalence survey we estimated the point prevalence of all complex wounds to be 1.47 per 1000 people (95% confidence interval 1.38 to 1.56 per 1000 people). Pressure ulcers and venous leg ulcers were the most common type of complex wound. A total of 195 people with a complex wound were recruited to a complex wounds register pilot. We established the feasibility of correctly identifying, extracting and transferring routine NHS data into the register; however, participant recruitment, data collection and tracking individual wounds in people with multiple wounds were challenging. Most patients and health professionals regarded healing of the wound as the primary treatment goal. Patients were greatly troubled by the social consequences of having a complex wound. Complex wounds are frequently a consequence of, and are themselves, a long-term condition but treatment is usually focused on healing the wound. Consultative, deliberative research agenda setting on pressure ulcer prevention and treatment with patients, carers and clinicians yielded 960 treatment uncertainties and a top 12 list of research priorities. Of 167 RCTs of complex wound treatments in a systematic review of study quality, 41% did not specify a primary outcome and the overall quality of the conduct and reporting of the research was poor. Mixed-treatment comparison meta-analysis in areas of high priority identified that matrix hydrocolloid dressings had the highest probability (70%) of being the most effective dressing for diabetic foot ulcers, whereas a hyaluronan fleece dressing had the highest probability (35%) of being the most effective dressing for venous ulcers; however, the quality of this evidence was low and uncertainty is high.ConclusionsComplex wounds are common and costly with a poor evidence base for many frequent clinical decisions. There is little routine clinical data collection in community nursing. A prospective complex wounds register has the potential to both assist clinical decision-making and provide important research evidence but would be challenging to implement without investment in information technology in NHS community services. Future work should focus on developing insights into typical wound healing trajectories, identifying factors that are prognostic for healing and assessing the cost-effectiveness of selected wound treatments.FundingThe National Institute for Health Research Programme Grants for Applied Research programme.

“…Capture-recapture methods have been used to assess and improve surveillance efforts for a wide range of conditions including sexually transmitted diseases, meningococcal infections, hepatitis A, tuberculosis, and adverse vaccine events [11,12,13,14,15,16], as well as various neurological disorders, and are increasingly in use for examining the prevalence of ALS [17,18,19,20]. Here we present the results of a capture-recapture analysis of a subset of the data collected in the State of Georgia from multiple sources, including Emory Healthcare, a community neurologist, Veterans Health Administration (VHA), Veterans Benefits Administration (VBA), Medicare, and Georgia mortality records, covering the 5-year period of 2001 through 2005.…”

Utility of Capture-Recapture Methodology to Assess Completeness of Amyotrophic Lateral Sclerosis Case Ascertainment

Background: With the establishment of a national amyotrophic lateral sclerosis (ALS) registry in the United States, methods are needed to ascertain the completeness of case ascertainment, especially in view of the proposal to rely largely on existing data sources. Methods: Data about ALS patients residing in the 5-county metropolitan Atlanta area (within the State of Georgia) from 2001 to 2005 were categorized according to their source – ALS Association, clinical (Emory Healthcare, community neurologist, Veterans Health Administration, Veterans Benefits Administration), Medicare and death certificates. ALS diagnoses were verified using chart review. Capture-recapture analyses were carried out using log-linear modeling, stratified by age and race. Results: The final model (based on 798 cases), which included the 4 main sources and 3 two-way interaction terms, yielded an estimated total population of 880 (95% CI 816–965), indicating that the combination of case-finding methods identified about 90.7% of cases. The estimated 5-year period prevalence is 38.5/100,000 (95% CI 35.66–42.19). Conclusion: This study highlights gaps in data based on existing data sources and illustrates a method for combining data from multiple sources to help facilitate the successful establishment of a US national ALS registry.

“…It is suggested that researchers in neurological epidemiology use this method when conducting incidence and prevalence studies [7]. In many ways, the CRM may actually be the 'gold standard' for estimating the number of cases as well as providing an estimate of the undercount of the lists [8]. The commentary of Lange et al [1] proposing the utilization of the capture-recapture method for the determination of the prevalence of neurocysticercosis (NC) is not appropriate.…”
