BackgroundThe Global Roadmap for Health Measurement and Accountability sees integrated systems for health information as key to obtaining seamless, sustainable, and secure information exchanges at all levels of health systems. The Global Strategy for Women’s, Children’s and Adolescent’s Health aims to achieve a continuum of quality of care with effective coverage of interventions. The WHO and World Bank recommend that countries focus on intervention coverage to monitor programs and progress for universal health coverage. Electronic health registries - eRegistries - represent integrated systems that secure a triple return on investments: First, effective single data collection for health workers to seamlessly follow individuals along the continuum of care and across disconnected cadres of care providers. Second, real-time public health surveillance and monitoring of intervention coverage, and third, feedback of information to individuals, care providers and the public for transparent accountability. This series on eRegistries presents frameworks and tools to facilitate the development and secure operation of eRegistries for maternal and child health.MethodsIn this first paper of the eRegistries Series we have used WHO frameworks and taxonomy to map how eRegistries can support commonly used electronic and mobile applications to alleviate health systems constraints in maternal and child health. A web-based survey of public health officials in 64 low- and middle-income countries, and a systematic search of literature from 2005–2015, aimed to assess country capacities by the current status, quality and use of data in reproductive health registries.ResultseRegistries can offer support for the 12 most commonly used electronic and mobile applications for health. Countries are implementing health registries in various forms, the majority in transition from paper-based data collection to electronic systems, but very few have eRegistries that can act as an integrating backbone for health information. More mature country capacity reflected by published health registry based research is emerging in settings reaching regional or national scale, increasingly with electronic solutions. 66 scientific publications were identified based on 32 registry systems in 23 countries over a period of 10 years; this reflects a challenging experience and capacity gap for delivering sustainable high quality registries.ConclusionsRegistries are being developed and used in many high burden countries, but their potential benefits are far from realized as few countries have fully transitioned from paper-based health information to integrated electronic backbone systems. Free tools and frameworks exist to facilitate progress in health information for women and children.Electronic supplementary materialThe online version of this article (doi:10.1186/s12884-016-0801-7) contains supplementary material, which is available to authorized users.

ObjectivesTimely recognition of medication misuse and dependence is crucial to avoid both adverse drug events and increasing health expenditure. Yet the detection of these disorders in older people remains challenging due to the paucity of evidence on characteristics of patients at risk. This study investigates sociodemographic, pharmacological and clinical characteristics and factors associated with prolonged medication use, misuse and dependence in hospitalised older patients, focusing on three commonly prescribed central nervous system depressants (CNSDs): opioid analgesics, benzodiazepines and z-hypnotics.DesignA prospective, cross-sectional study complying with the Strengthening the Reporting of Observational Studies in Epidemiology guidelines.SettingSomatic departments of the Akershus University Hospital, Norway.Participants246 patients aged 65–90 were included.Outcome measuresProlonged use was defined as using CNSDs for ≥4 weeks. Misuse and dependence were assessed with the Diagnostic and Statistical Manual of Mental Disorders, 4th Edition criteria for substance abuse and dependence. We used descriptive statistics to report patients’ characteristics and logistic regression to demonstrate factors associated with prolonged use, and misuse or dependence.ResultsForty per cent of participants reported using CNSDs for ≥4 weeks. The odds of prolonged use were higher for patients aged 75–84 (OR=2.32, 95% CI 1.16 to 4.65) and ≥85 (OR=3.33, 95% CI 1.25 to 8.87) vs <75 years, for pain intensity (OR=1.02, 95% CI 1.01 to 1.04), and polypharmacy versus no polypharmacy (OR=5.16, 95% CI 2.13 to 12.55). The odds were lower for patients who completed secondary education (OR=0.33, 95% CI 0.13 to 0.83) compared with those with only basic education. Factors associated with misuse or dependence were pain intensity (OR=1.02, 95% CI 1.01 to 1.04) and concurrent use of ≥2 CNSDs (OR=3.99, 95% CI 1.34 to 11.88).ConclusionCNSD overuse is prevalent among hospitalised older patients, despite clear guidelines and recommendations. Our findings underline a need for stronger focus on responsible prescribing, timely detection and prevention of this issue, with special attention towards older patients, those with enhanced pain, polypharmacy and/or concurrent use of several CNSDs.Trial registration numberNCT03162081.

Background In older patients, timely recognition and treatment of medication misuse and dependence are crucial to secure medication safety and to avoid increasing health expenditure. Nonetheless, the detection of this condition remains challenging due to the paucity of screening instruments validated for older people. This study assesses diagnostic accuracy, reliability, validity and the factor structure of the Severity of Dependence Scale (SDS) in detecting medication misuse and dependence among hospitalized older patients, focusing on prescribed central nervous system depressants (CNSDs): opioid analgesics, benzodiazepines and z-hypnotics. Methods 246 adults aged 65–90 were recruited consecutively from somatic departments of the Akershus University Hospital, Norway. Among these, 100 patients were identified as prolonged users of CNSDs. Diagnostic accuracy and validity of the SDS were assessed using DSM-IV criteria for substance abuse and dependence as the reference standard. We also performed an exploratory factor analysis and assessment of internal consistency using Cronbach’s alpha. Results The area under the ROC curve was 0.86 (95%CI = 0.79–0.93; p < 0.001). A score of 5.5 was determined as the optimal cutoff for detecting CNSD misuse and dependence among older patients. Cronbach’s alpha obtained was satisfactory (α = 0.73). There was a significant positive correlation between the SDS score and DSM-IV criteria for substance abuse and dependence (Pearson’s correlation coefficient = 0.61, p < 0.001). The uni-dimensionality of the SDS was documented. Conclusions The SDS is reliable, valid and capable of detecting medication misuse and dependence among hospitalized older patients, with good diagnostic performance. The scale thus holds promise for use in both clinical and research contexts. Trial registration ClinicalTrials.gov Identifier: NCT03162081 . Registered 3 May 2017.
