Impact of social accountability monitoring on health facility performance: Evidence from Tanzania.

Social accountability programs are increasingly used to improve the performance of public service providers in low-income settings. Despite their growing popularity, evidence on the effectiveness of social accountability programs remains mixed. In this manuscript, we assess the impact of a social accountability intervention on health facility management exploring quasiexperimental variation in program exposure in Tanzania. We find that the social accountability intervention resulted in a 1.8 SD reduction in drug stockouts relative to the control group, but did not improve facility infrastructure maintenance. The results of this study suggest that social accountability programs may be effective in areas of health service provision that are responsive to changes in provider behavior but may not work in settings where improvements in outcomes are conditional on larger health systems features.

Corona and coffee on your commute: a spatial analysis of COVID-19 mortality and commuting flows in England in 2020.

BACKGROUND: The COVID-19 pandemic forced governments to implement lockdown policies to curb the spread of the disease. These policies explicitly encouraged homeworking, hence reducing the number of commuters with the implicit assumption that restricting peoples' movement reduces risk of infection for travellers and other people in their areas of residence and work. Yet, the spatial interrelation of different areas has been rarely addressed both in the public discourse and in early accounts of the various consequences of COVID-19. METHODS: Our study proposes a spatial analysis of the association between commuting flows and COVID-19 mortality in England between March and June 2020, using a range of publicly available area-level data. To account for spatial correlation, we used a structural mobility gravity model to analyze commuting flows between Local Authority Districts. By accounting for these spatial dependencies, we temper concerns of bias and inefficiency affecting simple linear estimates. Additionally, we disentangle the direct and indirect (from other areas) influence of commuting on COVID-19 mortality. RESULTS: The results of our spatial regression models suggest that higher commuting flows-in general and particularly by public transport-are associated with higher COVID-19 mortality. Our results are consistent with a reduction in COVID-related mortality after the introduction of a national lockdown in March. The spatial-lag term is statistically significant, highlighting the importance of accounting for spatial dependencies. CONCLUSION: We suggest that considering spatial interactions through commuting or travel motivations may offer interesting perspectives on the trade-off between health and economic activity during lockdowns.

The clinical use of bone morphogenetic proteins revisited: a novel biocompatible carrier device OSTEOGROW for bone healing.

PURPOSE: The purpose of this study was to revise the clinical use of commercial BMP2 (Infuse) and BMP7 (Osigraft) based bone devices and explore the mechanism of action and efficacy of low BMP6 doses in a novel whole blood biocompatible device OSTEOGROW. METHODS: Complications from the clinical use of BMP2 and BMP7 have been systemically reviewed in light of their role in bone remodeling. BMP6 function has been assessed in Bmp6-/- mice by µCT and skeletal histology, and has also been examined in mesenchymal stem cells (MSC), hematopoietic stem cells (HSC) and osteoclasts. Safety and efficacy of OSTEOGROW have been assessed in rats and rabbits. RESULTS: Clinical use issues of BMP2 and BMP7 have been ascribed to the limited understanding of their role in bone remodeling at the time of device development for clinical trials. BMP2 and BMP7 in bone devices significantly promote bone resorption leading to osteolysis at the endosteal surfaces, while in parallel stimulating exuberant bone formation in surrounding tissues. Unbound BMP2 and BMP7 in bone devices precipitate on the bovine collagen and cause inflammation and swelling. OSTEOGROW required small amounts of BMP6, applied in a biocompatible blood coagulum carrier, for stimulating differentiation of MSCs and accelerated healing of critical size bone defects in animals, without bone resorption and inflammation. BMP6 decreased the number of osteoclasts derived from HSC, while BMP2 and BMP7 increased their number. CONCLUSIONS: Current issues and challenges with commercial bone devices may be resolved by using novel BMP6 biocompatible device OSTEOGROW, which will be clinically tested in metaphyseal bone fractures, compartments where BMP2 and BMP7 have not been effective.

[Temporary and permanent central venous catheters for hemodialysis]. / Primjena trajnih i privremenih centralnih venskih katetera za hemodijalizu.

The usage of temporary and permanent dialysis catheters for hemodialysis vascular access has been on continual increase. The reason for this increase is aging population on hemodialysis with blood vessels inappropriate for arteriovenous fistula creation. Complications may occur during catheter insertion as well as in the already inserted catheters, e.g., thrombosis and infections. The severity of complications is determined by experience of the operator as well as the quality and localization of blood vessels. Monitoring of dialysis catheter function, choice of the site of catheter insertion and methods of salvaging catheters from thrombosis and treating catheter-related local and systemic infections are described in this paper. Constant evaluation, proper care and hygiene of dialysis catheters are highly recommended.

Adoption of clinical pharmacist roles in primary care: Longitudinal evidence from English general practice.

BACKGROUND: Over the last decade, the number of clinical pharmacists working within multidisciplinary teams in English general practice has expanded Aim: This study examines changes in quality of prescribing after the adoption of clinical pharmacists in English general practices. METHODS: Two-way fixed effects regression was used to compare differences in prescribing indicators in general practices in England with and without pharmacists following implementation between September 2015 and December 2019 Results: Between September 2015 and December 2019, the proportion of practices employing a clinical pharmacist increased from 236/ 7,623 (3.10%) to 1,402/ 6,836 (20.51%). Clinical pharmacist implementation resulted in statistically significant reductions in total costs of medicines per 1,000 patients (-0.85% ,95% CI -1.50%, -0.21%), the total number of opioid prescriptions per 1,000 patients (- 1.06%, 95% CI -1.82%, -0.29%), and the average daily quantity (ADQs) of anxiolytics per 1,000 patients (-1.26%, 95% CI -2.40%, -0.12%). Clinical pharmacist implementation also resulted in reductions in the total number of prescriptions per 1,000 patients (-0.58%, 95% CI -1.30%, 0.13%), and the total number of antibiotic prescriptions per 1,000 patients (-0.51%, 95% CI -1.30%, 0.27%) that trended towards statistical significance. There were no statistically significant differences in the share of broad-spectrum versus narrow-spectrum antibiotics (0.02%, 95% CI -0.07%, 0.11%) and the oral morphine equivalence of high-dose opioids (>120mg per 24 hours) per 1,000 patients (1.19%, 95% CI -0.46%, 2.85%). CONCLUSION: Our analysis is limited by aggregate data at the practice-level but supports the hypothesis that clinical pharmacist implementation results in improvements in prescribing quality.

Free-for-all: Does crowding impact outcomes because hospital emergency departments do not prioritise effectively?

Unexpected peaks in volumes of attendances at hospital emergency departments (EDs) have been found to affect waiting times, intensity of care and outcomes. We ask whether these effects of ED crowding on patients are caused by poor clinical prioritisation or a quality-quantity trade-off generated by a binding capacity constraint. We study the effects of crowding created by lower-severity patients on the outcomes of approximately 13 million higher-severity patients attending the 140 public EDs in England between April 2016 and March 2017. Our identification approach relies on high-dimensional fixed effects to account for planned capacity. Unexpected demand from low-severity patients has very limited effects on the care provided to higher-severity patients throughout their entire pathway in ED. Detrimental effects of crowding caused by low-severity patients materialise only at very high levels of unexpected demand, suggesting that binding resource constraints impact patient care only when demand greatly exceeds the ED's expectations. These effects are smaller than those caused by crowding induced by higher-severity patients, suggesting an efficient prioritisation of incoming patients in EDs.

Outcomes for university students following emergency care presentation for deliberate self-harm: a retrospective observational study of emergency departments in England for 2017/2018.

OBJECTIVES: Identify university-aged students and contrast their healthcare provision and outcomes with other patients in the same age group attending emergency departments for deliberate self-harm. DESIGN: Retrospective cross-sectional observational study. SETTING: Patients visiting 129 public hospital emergency departments across England between April 2017 and March 2018. PARTICIPANTS: 14 074 patients aged 18-23 visiting emergency departments for conditions linked to deliberate self-harm, 1016 of which were identified as university-aged students. OUTCOME MEASURES: We study various outcomes across the entire patient pathway in the emergency department: waiting time to initial assessment on arrival at the emergency department, count of investigations delivered, discharge destination (patients refusing treatment or leave before being seen, referred to another provider or admitted to inpatient care, discharged with no follow-up) and unplanned follow-up visit within 7 days. RESULTS: We find a statistically significant difference of 0.262 (-0.491 to -0.0327) less investigations delivered to students compared with non-students (about 8% compared with the baseline number of investigations for non-students). Stratified analyses reveal that this difference is concentrated among students visiting the emergency department outside of regular working hours (-0.485 (-0.850 to -0.120)) and students visiting for repeated deliberate self-harm episodes (-0.881 (-1.510 to -0.252)). Unplanned reattendance within 7 days is lower among students visiting emergency departments during out of hours (-0.0306 (-0.0576 to -0.00363)), while students arriving by ambulance are less likely to be referred to another provider (-0.0708 (-0.140 to -0.00182)) compared with non-students. CONCLUSIONS: We find evidence of less-intense investigations being delivered to patients aged 18-23 identified as students compared with non-students visiting emergency departments after an episode of deliberate self-harm. Given the high risk of suicide attempts after episodes of deliberate self-harm among students, our findings may highlight the need for more focused interventions on this group of patients.

Do Informal Care Recipients Internalise Carer Burden? Examining the Impact of Informal Care Receipt on Health Behaviours.

BACKGROUND: Providing informal care has a negative effect on the caregiver's health and well-being, but little is known about how individuals respond to receiving informal care. Care recipients may improve their health behaviours to minimise the onerousness of caregiving and the stress faced by their carer from seeing a loved one in ill-health. OBJECTIVE: We aimed to examine whether informal care recipients internalise the potential for carer spillovers through changes in health behaviours. METHODS: We used data from 3250 older adults with care needs who took part in the UK Household Longitudinal Study between 2017 and 2019. We examined the response to informal care receipt in terms of the probability of engaging in four health behaviours: healthy diet, physical activity, smoking and alcohol consumption. We estimated average treatment effects using regression adjustment with inverse probability treatment weights, comparing individuals that received informal care to those receiving either formal or no care. RESULTS: We found that informal care receipt increased the probability of refraining from negative health behaviours (smoking and alcohol consumption) but reduced the probability of engaging in positive health behaviours (eating fruits and/or vegetables and physical activity). CONCLUSIONS: The asymmetric effects detected suggest that the underlying mechanisms are different, and care recipients may be engaging in risk and effort compensation between negative and positive health behaviours. Failure to account for the behavioural responses from informal care recipients may lead to under-estimation or over-estimation of the extent of caregiving burden and the effectiveness of interventions impacting informal carers.

Gender-related self-reported mental health inequalities in primary care in England: a cross-sectional analysis using the GP Patient Survey.

BACKGROUND: Transgender, non-binary, and gender diverse people face discrimination and barriers to accessing health care. Existing evidence suggests higher rates of mental health conditions among these groups compared with binary and cisgender groups. However, information is limited by poor gender recording in health records and surveys. We aimed to provide the first national estimates of gender-related inequalities in self-reported mental health conditions and mental health support across 15 gender groups in England. METHODS: We used changes to the 2021 and 2022 nationally representative cross-sectional English General Pracitioner (GP) Patient Surveys and used age-adjusted logistic regression to predict probabilities of two outcomes: first, self-reporting a mental health condition and second, self-reporting unmet mental health needs. We report results for 15 exposure groups: five gender groups (female, male, non-binary, prefer to self-describe, and prefer not to say), within three cisgender or transgender identity groups (cisgender, transgender, or prefer not to say). We explored potential mediation by adding covariates. FINDINGS: Of the 1 520 457 respondents in the estimation sample, 861 017 (51·4%) were female, 645 300 (47·4%) were male, 2600 (0·3%) were non-binary, 2277 (0·2%) self-described their gender, and 9263 (0·7%) preferred not to state their gender. 1 499 852 (98·3%) respondents were cisgender, 7994 (0·7%) were transgender, and 12 611 (1·0%) preferred not to say their cisgender or transgender identity. We found wide gender-related inequalities in the probability of self-reporting a mental health condition, with the highest probabilities among non-binary patients who were transgender (47·21% [95% CI 42·86-51·60]) or preferred not to say their cisgender or transgender identity (32·90% [26·50-40·00]), and among transgender patients who self-described their gender (35·03% [27·39-43·53]). With the exception of non-binary patients in each case, probabilities were lowest among cisgender patient groups (ranging from male at 8·80% [8·69-8·92] to female at 11·97% [11·86-12·07]) and patients who preferred not to say their cisgender or transgender identity (ranging from female 7·15% [6·06-8·42] to prefer to self-describe 10·37% [7·13-14·86]). Inequalities in other health conditions and socioeconomic factors might mediate some of these inequalities. Probabilities of self-reported unmet mental health needs were lowest among cisgender male (15·55% [15·33-15·76]) and female (15·93% [15·76-16·10]) patients with increased probabilities among all other groups, ranging from 19·95% (17·57-22·57) in transgender male patients to 28·64% (26·23-31·17) among patients who preferred not to say their gender or their cisgender or transgender identity. Inequalities in interactions with health-care professionals may mediate much of these inequalities. INTERPRETATION: Together with existing evidence, our findings showed large gender-related inequalities in self-reported mental health outcomes in England. Given the existence of self-reported unmet mental health needs, we suggest that better health care system inclusivity and health-care professional training are needed, alongside broader improvements in the social and legal environment for transgender, non-binary, and gender diverse people.

Online learning applied to a course on rational therapeutics: an international comparison between final year students of two medical schools.

INTRODUCTION: Poor prescribing is probably the most common cause of preventable medication errors and many of these events involve junior doctors. In 2009, an electronic problem-based therapeutics course developed at the University of Michigan Medical School (UMMS) was translated and adapted for use at the University of Zagreb Medical School (UZMS). METHODS: After students from both schools took the course in 2010, we compared their responses with an online questionnaire addressing the course quality and its effectiveness. RESULTS: There were no statistically significant differences in the overall average grades awarded for the course (UZMS 4.11 ± 0.86 vs. UMMS 3.96 ± 0.93; 95% CI mean difference (MD) -0.36, 0.07; P = 0.175) with both student groups expressing high satisfaction rates with its quality, accessibility and overall design. UZMS students reported spending less time working through the course than their American colleagues (2.14 ± 1.01 vs. 2.89 ± 1.02 on a five point Likert scale; 95% CI MD 0.51, 0.99; P < 0.05). Furthermore, Croatian students indicated greater difficulty with course materials (3.54 ± 0.59 vs. 3.25 ± 0.59; 95% CI MD -0.42, -0.15; P < 0,05) and weekly multiple choice questions (3.83 ± 0.62 vs. 3.4 ± 0.61; 95% CI MD -0.58, -0.29; P < 0,05) compared with the UMMS students. CONCLUSION: It is possible to adapt and translate successfully whole online teaching resources and implement them internationally in different countries and health care systems, achieving similar, high student satisfaction rates while decreasing administrative and cost burdens. Web based learning may have great potential to offer a cost effective and safe environment in which prescribing skills can be improved.

Evaluating primary care networks in low-income and lower middle-income countries: a scoping review.

INTRODUCTION: Primary care networks (PCNs) are claimed to be an effective model to organise and deliver primary healthcare through collaborative relationships and effective coordination of primary care activities. Though increasingly implemented in different contexts, there is limited evidence on the effectiveness of PCNs in low-income and lower middle-income countries (LLMICs). OBJECTIVE: Our scoping review aims to understand how PCNs in LLMICs have been conceptualised, implemented and analysed in the literature and further explores the evidence of the effectiveness of these networks. METHODS: We structured our review using Arksey and O'Malley's framework for scoping reviews and recommendations by Levac et al. We also used the population, concept and context (PCC) guide of the Joanna Briggs Institute (JBI) methodology for scoping reviews to define the search strategy. The identified documents were then mapped, using Cunningham's evaluation framework for health networks, to understand how PCNs are conceived in LLMIC settings. RESULTS: We identified 20 documents describing PCNs in five LLMICs. The selected documents showed differing forms and complexities of networks, with a majority resourced by government, non-governmental and donor entities. Most networks were mandated, and established with defined goals, although these were not always understood by stakeholders. Unlike PCNs in developed settings, the scoping review did not identify integration of care as a major goal for the establishment of PCNs in LLMICs. Network evaluation relationships, outputs and outcomes also varied across the five networks in the identified documents, and perceptions of effectiveness differed across stakeholder groups. CONCLUSION: PCNs in LLMICs benefit from clearly stated goals and measurable outcomes, which facilitates evaluation. In order to maximise the benefits, careful attention to the aspects of network design and operation is required. Future research work could shed light on some of the missing pieces of evidence on their effectiveness by, for example, considering differential consequences of modes of network establishment and operation, including unintended consequences in the systems within which they reside, and evaluating long-term implications.

Socioeconomic inequality in access to timely and appropriate care in emergency departments.

In publicly-funded healthcare systems, waiting times for care should be based on need rather than ability to pay. Studies have shown that individuals with lower socioeconomic status face longer waits for planned inpatient care, but there is little evidence on inequalities in waiting times for emergency care. We study waiting times in emergency departments (EDs) following arrival by ambulance, where health consequences of extended waits may be severe. Using data from all major EDs in England during the 2016/17 financial year, we find patients from more deprived areas face longer waits during some parts of the ED care pathway. Inequalities in waits are small, but more deprived individuals also receive less complex ED care, are less likely to be admitted for inpatient care, and are more likely to re-attend ED or die shortly after attendance. Patient-physician interactions and unconscious bias towards more deprived patients may be important sources of inequalities.

Skill-mix change and outcomes in primary care: Longitudinal analysis of general practices in England 2015-2019.

BACKGROUND: Increasing the employment of staff with new clinical roles in primary care has been proposed as a solution to the shortages of GPs and nurses. However, evidence of the impacts this has on practice outcomes is limited. We examine how outcomes changed following changes in skill-mix in general practices in England. METHODS: We obtained annual data on staff in 6,296 English general practices between 2015 and 2019 and grouped professionals into four categories: GPs, Nurses, Health Professionals, and Healthcare Associate Professionals. We linked 10 indicators of quality of care covering the dimensions of accessibility, clinical effectiveness, user experiences and health system costs. We used both fixed-effect and first-differences regressions to model changes in staff composition and outcomes, adjusting for practice and population factors. RESULTS: Employment increased over time for all four staff groups, with largest increases for Healthcare Professionals (from 0.04 FTE per practice in 2015 to 0.28 in 2019) and smallest for Nurses who experienced a 3.5 percent growth. Increases in numbers of GPs and Nurses were positively associated with changes in practice activity and outcomes. The introduction of new roles was negatively associated with patient satisfaction: a one FTE increase in Health Professionals was associated with decreases of 0.126 [-0.175, -0.078] and 0.116 [-0.161, -0.071] standard deviations in overall patient satisfaction and satisfaction with making an appointment. Pharmacists improved medicine prescribing outcomes. All staff categories were associated with higher health system costs. There was little evidence of direct complementarity or substitution between different staff groups. CONCLUSIONS: Introduction of new roles to support GPs does not have straightforward effects on quality or patient satisfaction. Problems can arise from the complex adaptation required to adjust practice organisation and from the novelty of these roles to patients. These findings suggest caution over the implementation of policies encouraging more employment of different professionals in primary care.

Primary care workforce composition and population, professional, and system outcomes: a retrospective cross-sectional analysis.

BACKGROUND: The diversification of types of staff delivering primary care may affect professional, population, and system outcomes. AIM: To estimate associations between workforce composition and outcomes. DESIGN AND SETTING: Cross-sectional analysis of 6210 GP practices from a range of geographical settings across England in 2019. METHOD: A multivariable regression analysis was undertaken, relating numbers of staff in four groups - GPs, nurses, healthcare professionals, and health associate professionals - to patient access and satisfaction, quality of clinical care and prescribing, use of hospital services, GP working conditions (subsample of practices), and costs to the NHS. Data were obtained from the GP Patient Survey 2019, Quality and Outcomes Framework, prescribing data, the Hospital Episode Statistics database, the NHS Payments to General Practice 2019/2020, and the Tenth National GP Worklife Survey 2019. RESULTS: Having additional GPs was associated with higher levels of satisfaction for the GPs themselves and for patients, whereas additional staff of other types had opposite associations with these outcomes. Having additional nurses and health associate professionals was associated with lower costs per prescription but more prescribing activity than having additional staff from the other two groups. Having more GPs was associated with higher costs per prescription and lower use of narrow-spectrum antibiotics compared with the other staff groups. Except for health associate professionals, greater staff numbers were associated with more hospital activity. CONCLUSION: Professional, population, and system outcomes showed a variety of associations with primary care workforce composition. Having additional nurses was associated with lower quality in some aspects, and higher costs and activity. The association between additional healthcare professionals or health associate professionals and higher costs was less than that for additional GPs, but was also linked to lower patient and GP satisfaction.

Framework for identification and measurement of spillover effects in policy implementation: intended non-intended targeted non-targeted spillovers (INTENTS).

BACKGROUND: There is increasing awareness among researchers and policymakers of the potential for healthcare interventions to have consequences beyond those initially intended. These unintended consequences or "spillover effects" result from the complex features of healthcare organisation and delivery and can either increase or decrease overall effectiveness. Their potential influence has important consequences for the design and evaluation of implementation strategies and for decision-making. However, consideration of spillovers remains partial and unsystematic. We develop a comprehensive framework for the identification and measurement of spillover effects resulting from changes to the way in which healthcare services are organised and delivered. METHODS: We conducted a scoping review to map the existing literature on spillover effects in health and healthcare interventions and used the findings of this review to develop a comprehensive framework to identify and measure spillover effects. RESULTS: The scoping review identified a wide range of different spillover effects, either experienced by agents not intentionally targeted by an intervention or representing unintended effects for targeted agents. Our scoping review revealed that spillover effects tend to be discussed in papers only when they are found to be statistically significant or might account for unexpected findings, rather than as a pre-specified feature of evaluation studies. This hinders the ability to assess all potential implications of a given policy or intervention. We propose a taxonomy of spillover effects, classified based on the outcome and the unit experiencing the effect: within-unit, between-unit, and diagonal spillover effects. We then present the INTENTS framework: Intended Non-intended TargEted Non-Targeted Spillovers. The INTENTS framework considers the units and outcomes which may be affected by an intervention and the mechanisms by which spillover effects are generated. CONCLUSIONS: The INTENTS framework provides a structured guide for researchers and policymakers when considering the potential effects that implementation strategies may generate, and the steps to take when designing and evaluating such interventions. Application of the INTENTS framework will enable spillover effects to be addressed appropriately in future evaluations and decision-making, ensuring that the full range of costs and benefits of interventions are correctly identified.

Pain relief in medical patients: does clinical judgment and prescribing knowledge suffice?

The aim of this study was to evaluate the quality of pain management in hospitalised patients. A cross-sectional study design that included all medical patients experiencing pain was used. Out of 167 patients hospitalized at the Department of Medicine at the University Hospital Zagreb, 41 patients were experiencing pain and 40 out of them received analgesics. Twenty-two out of 38 patients were treated for malignant pain, 16 for non-malignant pain, and 2 patients could not be classified. Adequate pain relief was reported in less than 25% of patients in both groups. Our study revealed under-prescribing of combination therapy, low utilization rates of strong opioids and prevailing "as needed" prescribing practice. In conclusion, unsatisfactory pain management in medical patients is often present if left solely to the clinical judgement and knowledge of the prescribing physician. Regular pain assessment, evidence-based guidelines, education and regular audits of implementation of these measures are a prerequisite for effective pain treatment, and should all be employed in patients experiencing pain.

Bad law or implementation flaws? Lessons from the implementation of the new law on epidemics during the response to the first wave of COVID-19 in Switzerland.

After the 2009-2010 H1N1 pandemic, Switzerland overhauled its 1970 law on epidemics. The reform aimed at improving early detection, surveillance, and preparedness for future outbreaks of infectious diseases. Notably, the law introduced stronger coordination between Federal and Cantonal authorities, better management tools and international cooperation. The new law entered into force in 2016 after a long legislative process. During the process, the law survived a referendum fuelled by concerns about vaccine safety and pharmaceutical industry interference. The law was first applied during the COVID-19 pandemic in early 2020. The epicentre of the outbreak in Europe was in Lombardy, a large Italian region adjacent to Switzerland and with strong economic ties with its southern region of Ticino. The first months of pandemic response highlighted two major weaknesses. Firstly, the mechanisms introduced by the new law did not ease the tension between Cantonal autonomy and central coordination of the pandemic response. Central and Cantonal authorities will need to put in place new rules and arrangements to avoid dangerous delayed responses to foreseeable problems related to the spread of infectious diseases. Secondly, relevant stakeholders excluded from the policymaking process (trade unions, firms, large industries) should be involved to allow the introduction of harsh restrictions when needed, both internally and in relation to cross-border workers.

A network analysis of patient referrals in two district health systems in Tanzania.

Patient referral systems are fragile and overlooked components of the health system in Tanzania. Our study aims at exploring patient referral networks in two rural districts in Tanzania, Kilolo and Msalala. Firstly, we ask whether secondary-level facilities act as gatekeepers, mediating referrals from primary- to tertiary-level facilities. Secondly, we explore the facility and network-level determinants of patient referrals focusing on treatment of childhood illnesses and non-communicable diseases. We use data collected across all public health facilities in the districts in 2018. To study gatekeeping, we employ descriptive network analysis tools. To explore the determinants of referrals, we use exponential random graph models. In Kilolo, we find a disproportionate share of patients referred directly to the largest hospital due to geographical proximity. In Msalala, small and specialized secondary-level facilities seem to attract more patients. Overall, the results call for policies to increase referrals to secondary facilities avoiding expensive referrals to hospitals, improving timeliness of care and reducing travel-related financial burden for households.

Clinical pharmacology consultation: a better answer to safety issues of drug therapy during pregnancy?

PURPOSE: drug safety classifications give a very basic estimation of risk and should only be used as general guideline when assessing risk of pregnancy-related drug exposure or planning treatment. We conducted a study to assess the strength of association between both the clinical pharmacologists' risk assessment and the FDA risk categorization, and adverse pregnancy outcomes. METHODS: we retrospectively reviewed records of 1,076 patients consecutively referred to the clinical pharmacology outpatient clinic for pregnancy-related drug exposure (2000-2008). Clinical pharmacologists' risk assessments were reviewed in relation to FDA drug categorization and available pregnancy outcomes. RESULTS: overall, clinical pharmacologists' risk estimation was in agreement with the FDA risk categorization system in only 28% of consulted women, and in only 9% of women with high-risk exposure (FDA DX). Clinical pharmacologists' risk assessment confirming high-risk drug exposure had a better positive predictive value for adverse pregnancy outcomes than the FDA DX categorization (25% vs 14% respectively), while the negative predictive values were similar (92% vs 94% respectively). Clinical pharmacologists' risk assessment was a better predictor of adverse pregnancy outcomes compared with FDA risk categorization (OR 2.11 [95%CI 1.5-3.1; p < 0.001] vs OR 1.52 [95%CI 1.1-2.1; p = 0.014] respectively). CONCLUSIONS: additional evaluation beyond the FDA drug classification is essential for safer and more rational drug use in pregnancy. Clinical pharmacologists who have undergone rigorous medical training are ideally placed to consult on administration of medicines in pregnant women, thus making the prescribing of treatments in that patient category substantially safer and more rational.

[ISKRA guidelines for antimicrobial prophylaxis in surgery--Croatian National Guidelines]. / Smjernice ISKRA za antimikrobnu profilaksu u kirurgiji--Hrvatske Nacionalne Smjernice.

Summary. The development of the Guidelines for perioperative prophylactic use of antimicrobial agents (further on Guidelines) was initiated by the Interdisciplinary Section for Antibiotic Resistance Control (ISKRA) of the Croatian Ministry of Health and Social Welfare in accordance with the principles of AGREE (Appraisal of Guidelines for Research and Evaluation) methodology which means that the guidelines are the result of a consensus between all involved professional societies. Guidelines were composed in order to improve antibiotic use in surgical professions. Data obtained from observational studies have shown that the use of antimicrobials in surgical professions is unsatisfactory, and since around 50% of all prescribed drugs in surgical professions refer to perioperative prophylaxis, such guidelines could significantly improve current negative trend and reduce the occurrence of infections in surgical patients as well as slow down the selection of resistant bacteria. In the introductory part of the guidelines, principles of perioperative prophylaxis are presented. The advantages and risks of prophylaxis are listed as well as factors that determine prophylaxis effectiveness. For easier orientation, surgical professions have been divided into basic surgical fields. In each field, the specificity of the field has been described followed by uniform structured tables and with every listed surgical procedure there is the most probable cause of infection, the drug of choice for prophylaxis, alternative drug, remark for particular surgical procedure and finally the grade of recommendation. The Guidelines do not cover perioperative prophylaxis in immunocompromised patients nor perioperative prophylaxis in children. The Guidelines do not cover all possible surgical interventions, but can be used as a basis for most surgical procedures performed in our hospitals. At the very end of these Guidelines, a comprehensive list of references enables all those interested to find further information and details about this topic. The revision of the Guidelines is planned in three years' time.
