Risk factors for non-participation in ivermectin and dihydroartemisinin-piperaquine mass drug administration for malaria control in the MASSIV trial

BACKGROUND

Mass Drug Administration (MDA) has become a mainstay for the control of several diseases over the last two decades. Successful implementation of MDA programmes requires community participation and can be threatened by systematic non-participation. Such concerns are particularly pertinent for MDA programmes against malaria, as they require multi-day treatment over several consecutive months. Factors associated with non-participation to the MDA campaign with ivermectin (IVM) and dihydroartemisinin-piperaquine (DHP) implemented within the MASSIV cluster randomized trial were determined.

METHODS

Coverage data was extracted from the MASSIV trial study database, with every datapoint being a directly observed therapy (DOT). A complete month of MDA was classified as receiving all three daily doses of treatment. For both ivermectin and DHP, ordinal logistic regression was used to identify individual and household level variables associated with non-participation.

RESULTS

For ivermectin, 51.5% of eligible participants received all 3 months of treatment while 30.7% received either one or two complete months. For DHP, 56.7% of eligible participants received all 3 months of treatment and 30.5% received either one or two complete months. Children aged 5-15 years and adults aged more than 50 years were more likely to receive at least one complete month of MDA than working age adults, both for ivermectin (aOR 4.3, 95% CI 3.51-5.28 and aOR of 2.26, 95% CI 1.75-2.95) and DHP (aOR 2.47, 95%CI 2.02-3.02 and aOR 1.33, 95%CI 1.01-1.35), respectively. Members of households where the head received a complete month of MDA were more likely to themselves have received a complete month of MDA, both for ivermectin (aOR 1.71, 95%CI 1.35-2.14) and for DHP (aOR 1.64, 95%CI 1.33-2.04).

CONCLUSION

Personal and household-level variables were associated with participation in the MDA programme for malaria control. Specific strategies to (increase participation amongst some groups may be important to ensure maximum impact of MDA strategies in achieving malaria elimination.

Underreporting of non-study cigarette use by study participants confounds the interpretation of results from ambulatory clinical trial of reduced nicotine cigarettes

BACKGROUND

As part of its comprehensive plan to significantly reduce the harm from tobacco products, the US Food and Drug Administration is establishing a product standard to lower nicotine in conventional cigarettes to make them "minimally addictive or non-addictive". Many clinical studies have investigated the potential impact of such a standard on smoking behavior and exposure to cigarette constituents. These ambulatory studies required participants who smoke to switch to reduced nicotine study cigarettes. In contrast to clinical trials on pharmaceuticals or medical devices, participants had ready access to non-study conventional nicotine cigarettes and high rates of non-study cigarette use were consistently reported. The magnitude of non-compliance, which could impact the interpretation of the study results, was not adequately assessed in these trials.

METHODS

We conducted a secondary analysis of data from a large, randomized trial of reduced nicotine cigarettes with 840 participants to estimate the magnitude of non-compliance, i.e., the average number of non-study cigarettes smoked per day by study participants assigned to reduced nicotine cigarettes. Individual participants' non-study cigarette use was estimated based on his/her urinary total nicotine equivalent level, the nicotine content of the study cigarette assigned and the self-reported number of cigarettes smoked, using a previously published method.

RESULTS

Our analysis showed that (1) there is a large variation in the number of non-study cigarettes smoked by participants within each group (coefficient of variation 90-232%); (2) participants in reduced nicotine cigarette groups underreported their mean number of non-study cigarettes smoked per day by 85-91%; and (3) the biochemical-based estimates indicate no reduction in the mean number of total cigarettes smoked per day for any group assigned to reduced nicotine cigarettes after accounting for non-study cigarettes.

CONCLUSIONS

High levels of non-compliance, in both the rate and magnitude of non-study cigarette use, are common in ambulatory reduced nicotine cigarette trials where participants have access to conventional nicotine non-study cigarettes. The potential impact of high non-compliance on study outcomes should be considered when interpreting the results from such ambulatory studies.

Evaluation of non-conformities in the drafting of bulletins for urine cytobacteriological examinations at Sikasso Hospital (Mali)

Background

Non-compliance in the drafting of examination bulletins makes it difficult to perform them and interpret the results. With the aim of continuously improving laboratory services and guaranteeing the quality of urine cytobacteriological examination (ECBU) results, we initiated this study to evaluate non-compliance in the drafting of ECBU reports.

Materials and methods

This was a retrospective descriptive cross-sectional study which focused on non-compliance in the drafting of ECBU reports analysed in the laboratory from January to December 2022.

Results

During the study period, we collected 383 non-compliant ECBU reports out of 672, with a frequency of 56.99%. Non-compliances were related to age (2.68%), profession (24.40%), clinical information (6.70%) and residence (52.08%). The majority of non-compliant reports came from the medicine (35.51%) and urology (25.85%) departments.

Conclusion

The high frequency of non-compliance is a cause for concern and is of concern to all prescribers in this hospital.

A systematic review of simulation studies which compare existing statistical methods to account for non-compliance in randomised controlled trials

INTRODUCTION

Non-compliance is a common challenge for researchers and may reduce the power of an intention-to-treat analysis. Whilst a per protocol approach attempts to deal with this issue, it can result in biased estimates. Several methods to resolve this issue have been identified in previous reviews, but there is limited evidence supporting their use. This review aimed to identify simulation studies which compare such methods, assess the extent to which certain methods have been investigated and determine their performance under various scenarios.

METHODS

A systematic search of several electronic databases including MEDLINE and Scopus was carried out from conception to 30th November 2022. Included papers were published in a peer-reviewed journal, readily available in the English language and focused on comparing relevant methods in a superiority randomised controlled trial under a simulation study. Articles were screened using these criteria and a predetermined extraction form used to identify relevant information. A quality assessment appraised the risk of bias in individual studies. Extracted data was synthesised using tables, figures and a narrative summary. Both screening and data extraction were performed by two independent reviewers with disagreements resolved by consensus.

RESULTS

Of 2325 papers identified, 267 full texts were screened and 17 studies finally included. Twelve methods were identified across papers. Instrumental variable methods were commonly considered, but many authors found them to be biased in some settings. Non-compliance was generally assumed to be all-or-nothing and only occurring in the intervention group, although some methods considered it as time-varying. Simulation studies commonly varied the level and type of non-compliance and factors such as effect size and strength of confounding. The quality of papers was generally good, although some lacked detail and justification. Therefore, their conclusions were deemed to be less reliable.

CONCLUSIONS

It is common for papers to consider instrumental variable methods but more studies are needed that consider G-methods and compare a wide range of methods in realistic scenarios. It is difficult to make conclusions about the best method to deal with non-compliance due to a limited body of evidence and the difficulty in combining results from independent simulation studies.

Risk characteristics of alcohol and/or drug misuse in repeat emergency department attendees for seizures: a case-control study

BACKGROUND

There is a bi-directional relationship between seizures and substance misuse, i.e., alcohol and recreational drugs. Seizures and substance misuse are recognised separately to influence increased emergency department (ED) admissions and early death. There is however no understanding of the cumulative influence of these matters on repeat ED attenders for seizures esp. as a third are likely to re-attend within the year. This case-control study compares the characteristics of people with substance misuse to those without substance misuse presenting recurrently with seizures to the ED.

METHODS

From a single ED serving a rural population in the Southwest of England, data of all people presenting more than once with a seizure over a 4-year period were examined. The diagnosis of alcohol or drug misuse, deaths, demographic characteristics, and service use were captured.

RESULTS

Of 450 repeat attenders, 95 had a recorded history of alcohol and/or drug problems. Those with substance misuse had double the mortality when adjusted for age and gender compared to those without. They were also more likely to be male, younger in age, have mental health issues, live in socially deprived neighborhoods, not take anti-seizure medications and not have had a specialist review in epilepsy services in the previous year. Nearly a quarter of those with addiction issues died in the 4-year period.

DISCUSSION

Service provision for this vulnerable group may need to be modelled along different lines to traditional approaches, such as an assertive outreach community-based service as provided for chronic psychiatric and addiction management.

TFOS Lifestyle: Impact of contact lenses on the ocular surface

Several lifestyle choices made by contact lens wearers can have adverse consequences on ocular health. These include being non-adherent to contact lens care, sleeping in lenses, ill-advised purchasing options, not seeing an eyecare professional for regular aftercare visits, wearing lenses when feeling unwell, wearing lenses too soon after various forms of ophthalmic surgery, and wearing lenses when engaged in risky behaviors (e.g., when using tobacco, alcohol or recreational drugs). Those with a pre-existing compromised ocular surface may find that contact lens wear exacerbates ocular disease morbidity. Conversely, contact lenses may have various therapeutic benefits. The coronavirus disease-2019 (COVID-19) pandemic impinged upon the lifestyle of contact lens wearers, introducing challenges such as mask-associated dry eye, contact lens discomfort with increased use of digital devices, inadvertent exposure to hand sanitizers, and reduced use of lenses. Wearing contact lenses in challenging environments, such as in the presence of dust and noxious chemicals, or where there is the possibility of ocular trauma (e.g., sport or working with tools) can be problematic, although in some instances lenses can be protective. Contact lenses can be worn for sport, theatre, at high altitude, driving at night, in the military and in space, and special considerations are required when prescribing in such situations to ensure successful outcomes. A systematic review and meta-analysis, incorporated within the review, identified that the influence of lifestyle factors on soft contact lens dropout remains poorly understood, and is an area in need of further research. Overall, this report investigated lifestyle-related choices made by clinicians and contact lens wearers and discovered that when appropriate lifestyle choices are made, contact lens wear can enhance the quality of life of wearers.

The Trial within Cohorts (TwiCs) study design in oncology: experience and methodological reflections

A Trial within Cohorts (TwiCs) study design is a trial design that uses the infrastructure of an observational cohort study to initiate a randomized trial. Upon cohort enrollment, the participants provide consent for being randomized in future studies without being informed. Once a new treatment is available, eligible cohort participants are randomly assigned to the treatment or standard of care. Patients randomized to the treatment arm are offered the new treatment, which they can choose to refuse. Patients who refuse will receive standard of care instead. Patients randomized to the standard of care arm receive no information about the trial and continue receiving standard of care as part of the cohort study. Standard cohort measures are used for outcome comparisons. The TwiCs study design aims to overcome some issues encountered in standard Randomized Controlled Trials (RCTs). An example of an issue in standard RCTs is the slow patient accrual. A TwiCs study aims to improve this by selecting patients using a cohort and only offering the intervention to patients in the intervention arm. In oncology, the TwiCs study design has gained increasing interest during the last decade. Despite its potential advantages over RCTs, the TwiCs study design has several methodological challenges that need careful consideration when planning a TwiCs study. In this article, we focus on these challenges and reflect on them using experiences from TwiCs studies initiated in oncology. Important methodological challenges that are discussed are the timing of randomization, the issue of non-compliance (refusal) after randomization in the intervention arm, and the definition of the intention-to-treat effect in a TwiCs study and how this effect is related to its counterpart in standard RCTs.

The Determinants of Non-compliance on Rabies Vaccination in North-West Peninsular Malaysia

INTRODUCTION

Rabies post-exposure vaccination (Rabies PEV) remains the most fundamental prevention of human Rabies if administered in a timely and appropriate manner. The study was aimed to determine the proportion and determinants of non-compliance on Rabies PEV among dog bite patients in Perlis, Malaysia from July 2015 to June 2020.

METHODS

A retrospective cohort study was conducted using Perlis Rabid Potential Animal Bite Registry data. Independent variables and compliance status were obtained from the registry. Logistic regression analysis was utilized on 507 dog bite patients.

RESULTS

Most of dog bite patients were age group of 46-60 years old (23.1%), male (61.3%), Chinese (49.5%), seeking treatment less than 24 h after the exposure (78.3%), category two of exposure (76.3%) and bitten on lower extremities (57.8%) by an owned dog (58.4%). Only 19.5% were non-compliance to Rabies PEV. Siamese had significantly two-timed (AOR: 2.00; 95% CI 1.06, 3.76) odd higher to become non-compliance. Being bitten during 3rd (AOR: 0.27; 95% CI 0.12, 0.59), 4th (AOR: 0.24; 95% CI 0.11, 0.52) and 5th (AOR: 0.20; 95% CI 0.09, 0.44) year of the outbreak had significantly lower odds to non-comply with Rabies PEV.

CONCLUSION

19.5% of dog bite patients still did not comply with the Rabies PEV series. Siamese would likely to non-comply whereas bitten on the 3rd, 4th and 5th years of outbreak less tendency to non-comply. Continuous health promotion to the public in the various languages despite outbreak status are ongoing to improve the perception of risk and benefit toward compliance of Rabies PEV.

[Multicenter editorial quality control of laboratory request forms in Niger]

Introduction

laboratory request forms (LRF) is a means of communication between the biologist and the clinician. In Niger, to our knowledge, no study focused on the editorial quality of LRF. The purpose of this study was to evaluate the editorial quality and cost of non-compliant LRF in four main hospitals in Niamey and the representation of the CERBA laboratory in Niger.

Methods

we conducted a multicenter, cross-sectional, descriptive study over a period of eight months. All LRFs sent to selected laboratories over the study period were included in this study.

Results

a total of 5.651 LRFs from 30 different clinical departments were included in this study. The most reported information in the LRFs was: the patient's last name (99.79%), first name (99.65%) and date of prescription (97.45%). On the other hand, the sample date, time, and nature were reported in 0.02%, 0.21%, and 1.68% of the LRFs respectively. Overall, 9.45% of the LRFs complied with the principles of good prescribing. While the bivariate analysis showed that doctors had a tendency to prescribe better than other health workers, multivariate analysis showed that the risk of non-compliance of LRFs was not associated with the prescriber's qualification, the requesting service, and the testing cost. Conclusion: the editorial quality of LRFs is very low in the health structures evaluated. These results highlight the need for effective communication between the physicians and the biologists and a rigorous attitude of laboratory staff regarding the management of non-conformities.

Simulations of topiramate dosage recommendations for poor compliance events

PURPOSE

To determine the influences of one or two consecutive missed topiramate (TPM) doses on TPM pharmacokinetics and to suggest the proper TPM replacement dosing schemes using Monte Carlo simulations.

METHODS

Monte Carlo simulations were performed for various replacement dosing schemes using the parameters from the published population pharmacokinetic models. The lowest percentage of deviation of simulated concentrations outside the reference range of 5-20 mg/L from the compliance scenario for each replacement dosing scheme was used as a criterion for choosing the proper replacement dosing scheme.

RESULTS

For the one missed dose, the replacement with an immediate regular dose and a partial dose resulted in the lowest and highest percentages of concentration below 5 mg/L, respectively. While the opposite results were observed for the upper bound of the reference range (20 mg/L). For the two consecutive missed doses, the replacement with one and a half-missed doses resulted in a lower percentage of deviation of concentrations below 5 mg/L from the compliance scenario than the replacement with one regular dose.

CONCLUSIONS

For the one missed dose, taking an immediate regular dose might be suitable for patients who require higher TPM levels, while for patients who require lower TPM levels, an immediate partial dose could be used. For the two consecutive missed doses, an immediate one and a half regular dose might be suitable. However, these results were merely based on simulations; thus, they should be used alongside the clinician's justification based on seizure control.

Undisclosed Sexual Risk Exposures: Results of a Nationwide Compliance Study among Whole Blood Donors in Germany

Background

Undisclosed sexual infection risks are the main reasons for transfusion transmissible infections in German blood donors that have qualified for donation by donor health interviews and questionnaires. Until now, data about compliance with deferral criteria were only available from post-donation interviews with infected donors, and information about the proportion of donors which did not disclose (sexual) risks at the donor health questionnaire was not available.

Methods

A prospective nationwide anonymous online survey was conducted to investigate compliance of whole blood donors with deferral criteria for sexual infection risks. Twenty-one blood establishments which represent 80% of the regular whole blood-donor population invited all donors which donated blood during an 8-week period between January and March 2020.

Results

14,882 participants completed the questionnaire. A relevant proportion of non-compliance was shown (3.0%, 95% CI: 2.7-3.3%) - with male donors being non-compliant significantly more frequently than females (3.5% vs. 2.2%, p < 0.001). A quarter of the non-compliant men were MSM (0.9%, 95% CI: 0.7-1.1%). Non-compliance was strongly associated with the perception that questions about sexual risk exposures are too private. This is in line with the finding that a large proportion of donors (21%) refused to answer at least one question about sexual infection risks.

Conclusion

The presented data, collected for the first time, is suitable for assessing the impact of changes in the donor selection process. Donor's limited willingness to provide detailed information about sexual risk behaviour has to be kept in mind when further strategies for fair appraisal of individual sexual infection risks will be discussed.

Non-compliance with a nurse's advice to visit the primary care provider: an exploratory secondary analysis of the TRIAGE-trial

Background

During the cluster randomised TRIAGE-trial, a nurse advised 13% of low-risk patients presenting at an emergency department in Belgium to visit the adjacent general practitioner cooperative. Patients had the right to refuse this advice. This exploratory study examines the characteristics of refusers by uncovering the determinants of non-compliance and its impact on costs, as charged on the patient’s invoice.

Methods

Bivariate analyses with logistic regressions and T-tests were used to test the differences in patient characteristics, patient status, timing characteristics, and costs between refusers and non-refusers. A chi-square automatic interaction detection analysis was used to find the predictors of non-compliance.

Results

23.50% of the patients refused the advice to visit the general practitioner cooperative. This proportion was mainly influenced by the nurse on duty (non-compliance rates per nurse ranging from 2.9% to 52.8%) and the patients’ socio-economic status (receiving increased reimbursement versus not OR 1.37, 95%CI: 0.96 to 1.95). Additionally, non-compliance was associated (at the 0.10 significance level) with being male, not living nearby and certain reasons for encounter. Fewer patients refused when the nurse perceived crowding level as quiet relative to normal, and more patients refused during the evening. The mean cost was significantly higher for patients who refused, which was a result of more extensive examination and higher out-of-pocket expenses at the ED.

Conclusions

The nurse providing the advice to visit the general practitioner cooperative has a central role in the likelihood of patients’ refusal. Interventions to reduce non-compliance should aim at improving nurse-patient communication. Special attention may be required when managing patients with a lower socio-economic status. The overall mean cost was higher for refusers, illustrating the importance of compliance.

Trial registration

The trial was registered on registration number NCT03793972 on 04/01/2019.

An Ethnographic Examination of People's Reactions to State-Led COVID-19 Measures in Sierra Leone

This paper explores how individuals-defined along lines of gender, age, life experience, financial capital and profession-experience and react in nuanced ways to the impacts of state-led COVID-19 measures, in Sierra Leone. The findings are based on ethnographic data collected from Makeni city and three rural communities in Bombali District, north Sierra Leone during the outbreak of COVID-19, between 23rd March and 6th May 2020. The findings show how state-led measures-indefinite district lockdown, three-day total lockdowns and mask wearing-were experienced and responded to in myriad ways, including adapting, not complying and resisting. The diverse ways members of society experience, react and shape the effects of internationally and nationally informed health policies during a global pandemic in Sierra Leone highlight the nuances of individual experience and agency in specific socio-political contexts. These findings contribute to the emerging Social Science debate on state-society relations in the COVID-19 pandemic response.

Risk factors analysis of non-compliance of Tuberculosis (TB) patients taking medicine in Puskesmas Polonia, Medan, 2021

OBJECTIVE

This study aims to analyze the risk factors (knowledge, role of health workers, drug Consumption Supervisors activity, side effects of drugs, duration of taking medication, and feeling healthy) for non-adherence to TB patients taking medication at the Puskesmas.

METHOD

The research design used in this study was a case control where the population was all patients who visited the working region of the Polonia Public Health Center. The research subjects were 138 samples consisting of 68 cases and 68 controls. The data were analyzed using a tabulation and statistical system using the SPSS program with the Odds ratio test and logistic regression.

RESULT

It was found that there was an influence on the role of health workers OR=8,933 (95% CI: 1,085-73.525), side effects of drugs with OR=6,873 (95% CI; 2,435-19,398), felt healthy OR=4,643 (95% CI; 1,247-17,287), and knowledge OR=2,700 (95% CI; 1,083-6,731) It is recommended to be healthy and monitor the occurrence of drug side effects in patients during treatment.

Pregnancy and the Control of Epileptic Seizures: A Review

Over the past 50 years, published studies have provided quantitative data on the control of epileptic seizures during pregnancy. The studies have varied in quality, and particularly in the ways in which seizure control has been assessed. However, most studies have shown that seizure occurrence rates are more likely to worsen than improve during pregnancy, though in most pregnancies the rates have been unaltered. Nearly all of the studies have involved women with antiseizure medication-treated epilepsy, but there is a little evidence that seizure control also tends to worsen in pregnancies of women with untreated epilepsy. The factors likely to contribute to the seizure worsening are (i) patient non-compliance, (ii) increased antiseizure medication clearance during pregnancy resulting in lower circulating drug concentrations relative to dose, (iii) the effects of the higher female sex hormone levels during pregnancy, oestrogens being pro-epileptogenic and progesterone anti-epileptogenic, and (iv) reluctance to use the potential teratogen valproate in women capable of pregnancy, depriving them of the most effective drug for certain types of epilepsy. Compliance can be encouraged, but at the present time only one other factor is readily correctable, i.e. the increased drug clearance. This can be compensated for by raising antiseizure medication dosage during pregnancy, guided by measurement of circulating drug concentrations. This course of action appears to reduce the chance of seizure disorder worsening during pregnancy, but so far it has not provided a complete solution to the issue.

Underground COVID-19 Home Hospitals for Haredim: Non-Compliance or a Culturally Adapted Alternative to Public Hospitalization?

This thematic study analyzed the experiences of Jewish Haredi (Lithuanian) patients in underground home hospitals during the second wave of COVID-19 in Israel. This minority comprises 12.6% of the Israeli population. Participants were 30 members of this hidden population, ages 59-78. Haredi complied with community directives rather than with the national directive of hospitalizing COVID-19 patient only at public hospitals. Compliance with community directives was driven by a distrust in health authorities and clinicians at public hospitals; by the preference of patient-centered care, a desired approach of care that public hospitals fail to implement; by the need to sustain beliefs, values, and traditions; by community leadership; and by the need to conserve political power. While health authorities view underground home hospitals as demonstrating non-compliance with the national directive, Haredi leaders view underground home hospitals as demonstrating a self-sufficient, patient-centered care alternative to public hospitalizations. Considering the benefits of patient-centered care and the growth of the multi-cultural global landscape, we call upon health authorities to explore the accommodation of patient-centered care for COVID-19 patients and the designing of an adaptive multi-cultural policy that address multi-cultural aspects of religious minorities as key to health promotion. We propose ways to implement multi-cultural policies.

Asking sensitive questions in conservation using Randomised Response Techniques

Conservation increasingly seeks knowledge of human behaviour. However, securing reliable data can be challenging, particularly if the behaviour is illegal or otherwise sensitive. Specialised questioning methods such as Randomised Response Techniques (RRTs) are increasingly used in conservation to provide greater anonymity, increase response rates, and reduce bias. A rich RRT literature exists, but successfully navigating it can be challenging. To help conservationists access this literature, we summarise the various RRT designs available and conduct a systematic review of empirical applications of RRTs within (n = 32), and beyond conservation (n = 66). Our results show increased application of RRTs in conservation since 2000. We compare the performance of RRTs against known prevalence of the sensitive behaviour and relative to other questioning techniques to assess how successful RRTs are at reducing bias (indicated by securing higher estimates). Findings suggest that RRT applications in conservation were less likely than those in other disciplines to provide prevalence estimates equal to, or higher than those derived from direct questions. Across all disciplines, we found reports of non-compliance with RRT instructions were common, but rarely accounted for in study design or analysis. For the first time, we provide conservationists considering RRTs with evidence on what works, and provide guidance on how to develop robust designs suitable for conservation research contexts. We highlight when alternate methods should be used, how to increase design efficiency and improve compliance with RRT instructions. We conclude RRTs are a useful tool, but their performance depends on careful design and implementation.

Non-compliance to practice guidelines still exist in the early management of acute pancreatitis: Time for reappraisal?

INTRODUCTION

Earlier national surveys on the management of acute pancreatitis (AP) had reported non-compliance to practice guidelines. In the past decade, several guidelines were revised based on new evidence. In this multicenter international survey, we aimed to evaluate the practice patterns of early management of AP and compliance to the revised treatment guidelines across different disciplines and practice environments.

METHODS

A structured questionnaire was sent via email to a target population of 654 that constituted of medical and surgical gastroenterologists, physicians and general surgeons, paediatricians from academic and non-academic centres across 30 countries. Other than demographic variables, the questionnaire contained items pertaining to early management of AP, such as, assessment at admissions and within first 72 h s, details regarding analgesics, IV hydration, oral/enteral feeding and antibiotic use.

RESULTS

The response rate was 46.2% and after exclusions, a total of 297 participant's responses were analysed. Majority of the participants were from Asia, followed by Europe and the Americas. 181 (60.9%) claimed to follow practice guidelines, out of which 59 (32.6%) followed more than one. On further probing, only 41.9% were actually compliant to feeding and 59.7% to antibiotic guidelines. Even though participants opted for aggressive hydration, early feeding and avoidance of prophylactic antibiotics, there were non-compliance and discrepancies in titration of fluid therapy, indications of feeding and antibiotic use.

DISCUSSION

Discrepancies and non-compliance still appear to exist in the early management of AP due to lack of strong evidence. We discuss ways that could improve compliance to the existing guidelines until stronger evidence comes to the fore.

Characteristics and patient-reported outcomes associated with dropout in severely affected oncological patients: an exploratory study

BACKGROUND

Patient-reported outcome measures (PROMs) are commonly-used surrogates for clinical outcomes in cancer research. When researching severe diseases such as cancer, it is difficult to avoid the problem of incomplete questionnaires from drop-outs or missing data from patients who pass away during the observation period. The aim of this exploratory study was to explore patient characteristics and the patient-reported outcomes associated with the time-to-dropout.

METHODS

In an Oncological Social Care Project (OSCAR) study, the condition of the participants was assessed four times within 12 months (t0: baseline, t1: 3 months, t2: 6 months, and t3: 12 months) by validated PROMs. We performed competing-risk regressions based on Fine and Gray's proportional sub-distribution hazards model for exploring factors associated with time-to-dropout. Death was considered a competing risk.

RESULTS

Three hundred sixty-two participants were analyzed in the study. 193 (53.3%) completed a follow-up after 12 months, 67 (18.5%) patients dropped out, and 102 patients (28.2%) died during the study period. Poor subjective social support was related to a higher risk of drop-out (SHR = 2.10; 95%CI: 1.01-4.35). Lower values in health-related quality of life were related to drop-out and death. The sub-scales global health status/QoL, role functioning, physical functioning, and fatigue symptom in the EORTC QLQ-C30 were key characteristics of early drop-out.

CONCLUSION

Severely affected cancer patients with poor social support and poor quality of life seem more likely to drop out of studies than patients with higher levels of social support and a better quality of life. This should be considered when planning studies to assess advanced cancer patients. Methods of close continued monitoring should be actively used when patient experiences a substantial deterioration in their health-related quality of life and symptoms during the study. Results for such studies have to be interpreted with caution in light of specific drop-out mechanisms.

TRIAL REGISTRATION

OSCAR study was registered to the German Clinical Trials Register (DRKS-ID: DRKS00013640 ). Registered 29 December 2017.

The impact of patient behaviour and care system compliance on reusable soft contact lens complications

Reusable soft daily wear contact lenses (CLs) remain popular and were fit to just over half of all wearers in the most recent international CL prescribing survey. Unlike daily disposable CLs, reusables require cleaning and disinfecting after every use, along with storage in a CL case. These additional requirements add a number of steps to the daily wear and care routine, increasing the opportunities for CL wearers to exhibit non-compliant behaviour. The impact of non-compliance ranges from poor lens comfort through to potentially sight-threatening infective keratitis. The coronavirus pandemic has refocused the profession on the importance of hand hygiene in particular, and the need for promoting safe CL wear in general. This review summarises typical non-compliant behaviour related to reusable CLs, and examines strategies and opportunities to better support wearers. Patient education has a central role in encouraging compliant behaviour, although patient recall of information is low, and personal belief systems may result in continuation of non-compliant behaviour despite awareness of the risks. CL care solutions are required for the daily disinfection of lenses, however misuse of multipurpose solutions (MPS) and hydrogen peroxide (H₂O₂)-based care systems can challenge their ability to be fully efficacious. Standard efficacy testing is reviewed, with consideration of how well current protocols model real-world use of CL solutions. Although some recommendations are in place for the inclusion of additional variables such as lens cases, CL materials, organic soil and efficacy against Acanthamoeba, opportunity still exists to reevaluate global standards to ensure consistency of testing in all markets. Finally, potential future innovations are discussed which may further support increased safety in reusable lens wear through novel antimicrobial additions to both CL materials and cases.

Barriers to medication adherence in the emergency department: A cross-sectional study

BACKGROUND

Medication nonadherence is a common problem that leads to increased healthcare utilization. It is unclear how patient insight and attitude towards their medications affect adherence in the ED. Furthermore, it is unclear how perceived medication importance differs between patients and ED physicians.

METHODS

We conducted a cross sectional study of adult patients presenting to 2 academic emergency departments from April 2015 to October 2016. Demographic data were collected and questions were asked regarding medication knowledge, perceived importance, and adherence. We also compared perceived importance of medications between patients and two physician raters. Inter-rater agreement was reported as raw percentages, and categorical data were compared using chi-squared analysis.

RESULTS

We identified 1268 patients, representing 4634 individual medications. We identified a significant association between knowledge of medications and perceived importance (p < .05). Secondarily, importance level was highly associated with medication adherence (p < .05). When ranking those medications that were considered "least" and "most" important among each patient's med list, our two physicians agreed with patients only 34.1% and 37% of the time respectively, as opposed to 62% and 62.8% agreement between each other.

CONCLUSIONS

These data suggest that there is a difference in perceived medication importance between ED physicians and ED patients. Knowledge of a medication's purpose is significantly associated with perceived importance, while this importance appears to be significantly associated with compliance. These results suggest that concerted efforts by ED physicians and staff to educate patients on the utility and importance of their medications may improve adherence.

Official controls on food safety: Competent Authority measures

Since December 14^th, 2019, Regulation (EC) No 882/2004 has been replaced by Regulation (EU) 2017/625, which sets the activity of the official control on food safety, extending the scope of the previous regulation. The broader scope of the new regulation aims to ensure compliance across the European Member States in the Union in the fields of food, feed, animal health and welfare, plant health and plant protection products. The administrative measures that the Competent Authorities adopt following the finding of a non-compliance regarding food hygiene, should be take into account not only the risk assessment, but a series of criteria dictated by both European and national legislation and comply with the generals principles governing administrative action. The aim of this study is to conduct a legal analysis of: (i) the provisions set out in Regulation (EU) 2017/625 concerning executive actions in the case of noncompliance, and (ii) the criteria used to assess the appropriate remedial measures. The study was completed by analysing recent legal cases on food safety, which in many cases have censure the work of the Local Competent Authority, and has brought to light a distorted and uneven application of the legislation on food safety, especially in cases in which drastic measures had been adopted, such as the closure of the productive activities, which has a heavy impact on the food business operators in the food sector concerned. In addition to an incorrect application of the specific health legislation, there is also a violation of the principle of proportionality, of community origin. Indeed, the principle of proportionality, an essential factor in administrative review, which has been used as a leading criterion in the adoption of administrative measures by of the Health Authorities of the Competent Authority.

Adequate timing and constant supervision are the keys for successful implementation of levothyroxine or levothyroxine/paracetamol absorption test

Background

Levothyroxine (LT₄) pseudomalabsorption due to medication non-adherence results in significant costs for Health Service. High dose LT₄ or LT₄/paracetamol absorption test is used in such cases. Hence, establishment of an optimal test protocol and timing of sample collection is of utmost importance.

Case presentation

A 34-year old woman was admitted to our Department because of severe hypothyroidism [on admission thyrotropin (TSH) > 100 μIU/ml, free thyroxine (FT₄) 0.13 ng/dl (ref. range 0.93–1.7)] despite apparently taking 1000 μg of LT₄ a day. Autoimmune hypothyroidism had been diagnosed 4 years before during post-partum thyroiditis. Subsequently, it was not possible to control her hypothyroidism despite several admissions to two University Hospitals and despite vehement denial of compliance problems. There was no evidence of coeliac disease or other malabsorption problems, though gluten-free and lactose-free diet was empirically instigated without success. A combined paracetamol (1000 mg)/LT₄ (1000 μg) absorption test was performed in one of these Hospitals. This showed good paracetamol absorption (from < 2 μg/ml to 14.11 μg/ml at 120 min), with inadequate LT₄ absorption (FT₄ increase from 5.95 pmol/l to 9.92 pmol/l at 0 and 120 min respectively). About 2 years prior to admission to our Department the patient was treated with escalating doses of levothyroxine [up to 3000 μg of T₄ and 40 μg of triiodothyronine (T₃) daily] without significant impact on TSH (still > 75 μIU/ml, and FT₄ still below reference range).

After admission to our Department we performed a 2500 μg LT₄ absorption test with controlled ingestion of crushed tablets, strict patient monitoring and sampling at 30 min intervals. We observed a quick and striking increase in FT₄ from 0.13 to 0.46, 1.78, 3.05 and 3.81 ng/dl, at 0, 30, 60, 90 and 120 min, respectively. Her TSH concentration decreased to 13.77 μIU/ml within 4 days. When informed, that we had managed to “overcome” her absorption problems, she discharged herself against medical advice and declined psychiatric consultation.

Conclusions

Adequate patient supervision and frequent sampling (e.g. every 30 min for 210 min) is the key for successful implementation of LT₄ absorption test. Paracetamol coadministration appears superfluous in such cases.

Pavlik harness and Frejka pillow: compliance affects results of outpatient treatment

PURPOSE OF THE STUDY

Outpatient treatment of hip dysplasia in newborns has excellent results. A combination of general screening with early treatment with a functional abduction device works well. Treatment with the Frejka pillow and the Pavlik harness is frequently used in our region. The aim of the study is to compare efficiency and treatment duration, related to the brace used, and to prove that the choice of an abduction device implies parental compliance with the treatment protocol.

MATERIALS AND METHODS

Data of 286 treated children were analyzed. The diagnosis was made in the first weeks of life by clinical and sonographic examinations during general screening. The choice of treatment device was expert dependent and was involved by many variables. The experience, type of clinical finding and sonographic pathology according to Graf, availability of a treating facility, and the potential cooperation of individual parents were major parameters. The Frejka pillow was used to treat 145 children and the Pavlik harness was used in 137 children. The treatment duration and percentage of infants lost from follow-up in relation to the device used was documented.

RESULTS

The success rate of outpatient treatment was 98.6%. In six patients, the type of device had to be changed during the treatment period. Physiological sonographic findings were achieved in all hips by the end of the treatment. The Frejka pillow was used as the preferred device in milder stable dysplastic hips, while unstable and decentered hips were treated more frequently with the Pavlik harness. Treatment lasted, on average, 95 days and 119 days in the Frejka and in the Pavlik group, respectively; there was no statistical significance in treatment duration of comparable sonographic pathologies. We observed statistically greater parental non-compliance with the treatment protocol in the Pavlik harness group (p = 0.0279; OR 2.7; 95% CI 1.07; 8.5).

CONCLUSIONS

Neither of the abduction devices was inferior with regard to treatment efficiency. We found that parental cooperation was an important factor during screening and treatment. The treatment decision and the choice of the brace must be made with full consent of the parents, keeping in mind that comfort during the nursing care may have a significant influence on compliance with the treatment protocol.

Noncompliance of the postexposure prophylactic vaccination following animal bites reporting to a rural primary health center

CONTEXT

Man lives in close harmony with animals and so the chances of injuries and diseases contracted from them. Effective preventive measure such as vaccination is to be ensured following harmful bites resulting in Rabies.

AIM

The aim is to assess the proportion of rabid animal bite cases and non-compliance of post exposure prophylaxis vaccination following bites, reporting to a rural primary health care centre.

SETTING AND DESIGN

This is a retrospective cross sectional study from records of animal bite cases attending a rural primary health centre from January 2017 to December 2017.

MATERIALS AND METHODS

A pre-designed case record form was used to estimate the proportion of animal bite cases leading to Rabies and Non-compliance of post exposure prophylaxis attending the health centre.

STATISTICAL ANALYSIS

Data analysis was done in SPSS 2016. Chi square was used to find the significance.

RESULTS

Around 448 animal bites were found over a span of one year, out of which 222 (49.5%) were found to be rabid animal bites. 46.65% (209) were dog bites and 2.9% (13) were cat bites. Statistical significance (P < 0.05) was seen between age and compliance of vaccination following dog bites. 1.14% of the study subjects who had completed the 5 dose post prophylaxis vaccination belonged to the elderly age group. Among the cat bite cases, 2 of the study subjects had received 1 dose of PEP with anti-rabies vaccine.

CONCLUSION

Only 1.14% of the study subjects had taken the complete dose of PEP. This suggests the lack of awareness among public and lack of services and supervision for rabid animal bites in rural areas. It is the duty of every physician to counsel people, co-ordinate with veterinary physician and maintain proper records so as to ensure completion of PEP to prevent rabies related deaths in humans.

Patient Compliance: Fact or Fiction?

The word ‘compliance' comes from the Latin word complire, meaning to fill up and hence to complete an action, transaction, or process and to fulfil a promise. In the Oxford English Dictionary, the relevant definition is ‘The acting in accordance with, or the yielding to a desire, request, condition, direction, etc.; a consenting to act in conformity with; an acceding to; practical assent”. Compliance with therapy is simply patients understanding of medication, motivation toward having this medication is a prescribed manner with the belief that the prescriber and prescribed medicine will be beneficial for his well-being. Although this is often the case, in a number of situations, the physician and pharmacist have not provided the patient with adequate instructions or have not presented the instructions in such a manner that the patient understands them. Nothing should be taken for granted regarding the patient's understanding of how to use medication, and appropriate steps must be taken to provide patients with the information and counseling necessary to use their medications as effectively and as safely as possible. 20% to 30% of new prescriptions are never filled at the pharmacy. Medication is not taken as prescribed 50% of the time. For patients prescribed medications for chronic diseases, after six months, the majority take less medication than prescribed or stop the medication altogether. There are both federal and state laws that make using or sharing prescription drugs illegal. If someone take a pill that was prescribed to someone else or give that pill to another person, not only is it against the law, it's extremely dangerous.

Impact of psychosocial comorbidities on clinical outcomes after liver transplantation: Stratification of a high-risk population

BACKGROUND

Liver transplantation is the accepted standard of care for end-stage liver disease due to a variety of etiologies including decompensated cirrhosis, fulminant hepatic failure, and primary hepatic malignancy. There are currently over 13000 candidates on the liver transplant waiting list emphasizing the importance of rigorous patient selection. There are few studies regarding the impact of additional psychosocial barriers to liver transplant including financial hardship, lack of caregiver support, polysubstance abuse, and issues with medical non-compliance. We hypothesized that patients with certain psychosocial comorbidities experienced worse outcomes after liver transplantation.

AIM

To assess the impact of certain pre-transplant psychosocial comorbidities on outcomes after liver transplantation.

METHODS

A retrospective analysis was performed on all adult patients from 2012-2016. Psychosocial comorbidities including documented medical non-compliance, polysubstance abuse, financial issues, and lack of caregiver support were collected. The primary outcome assessed post-transplantation was survival. Secondary outcomes measured included graft failure, episodes of acute rejection, psychiatric decompensation, number of readmissions, presence of infection, recidivism for alcohol and other substances, and documented caregiver support failure.

RESULTS

For the primary outcome, there were no differences in survival. Patients with a history of psychiatric disease had a higher incidence of psychiatric decompensation after liver transplantation (19% vs 10%, P = 0.013). Treatment of psychiatric disorders resulted in a reduction of the incidence of psychiatric decompensation (21% vs 11%, P = 0.022). Patients with a history of polysubstance abuse in the transplant evaluation had a higher incidence of substance abuse after transplantation (5.8% vs 1.2%, P = 0.05). In this cohort, 15 patients (3.8%) were found to have medical compliance issues in the transplant evaluation. Of these specific patients, 13.3% were found to have substance abuse after transplantation as opposed to 1.3% in patients without documented compliance issues (P = 0.03).

CONCLUSION

Patients with certain psychosocial comorbidities had worse outcomes following liver transplantation. Further prospective and multi-center studies are warranted to properly determine guidelines for liver transplantation regarding this high-risk population.

Precarious hope and reframing risk behavior from the ground up: insight from ethnographic research with Rwandan urban refugees in Yaoundé, Cameroon

Background

Theoretical and methodological research on risk-taking practices often frames risk as an individual choice. While risk does occur at individual level, it is determined by aspirations which are connected to others and society. For many displaced women globally, these aspirations are often linked to the well-being of their children and other household members. This article explores the links between aspirations for the future, gendered household dynamics, and health risk-taking behavior among the Rwandan urban refugee community.

Methods

This analysis drew from participant observation, focus group discussions, and in-depth interviews with 49 male and 42 female household members from 36 Rwandan refugee households in Yaoundé, Cameroon. The fieldwork was conducted over 12 months between May–August 2016, May–August 2017, and February–August 2018.

Results

We observed that while there was considerable convergence among household members in aspirations, there was considerable difference in risk-taking practices engaged to achieve them with women often assuming the greatest risks. These gendered realities of risk were not only related to structural concerns including access to different forms of capital, but also to socio-cultural gendered expectations of women, how risks were defined and justified, and household dynamics that drove the gendered reality of observed risk-behavior.

Conclusions

Humanitarian programs and policies are distinctly finite in nature; focused on the short-term needs of persons affected by conflict. However, many humanitarian situations in the world are protracted. In the midst of these challenges, themes of future-orientation, possibilities, and shared aspirations for a better future emerge. These aspirations and the practices, including risk-taking practices that stem from them are central to understand if we are to ensure a just peace and stability in displaced communities throughout the developing world. Our analysis highlights the need to examine sociocultural dimensions related to hopes for the future, gender, and household dynamics as a way to understand risk behavior. We propose this can be done through a framework of precarious hope which we put forward in this paper, in which hope, agency, sociocultural and political economic contexts situate risk as a gendered practice of hope amidst constraint.

Analysis of non-compliance with smoke-free legislation in Russia

OBJECTIVES

The study examined the smokers' non-compliance rates in indoor public places in Russia and the sociodemographic factors associated with non-compliance.

METHODS

Univariate analysis and logistic regression models were performed using cross-sectional data from a representative sample of Russian adults (N = 4006).

RESULTS

27.2% of Russian smokers did not comply with smoke-free bans. Non-compliance was attributed to sociodemographic characteristics of smokers, mainly to the number of cigarettes smoked per day, regular alcohol consumption, being aged between 15 and 34 years, being in the highest income group and living in an urban area. Neither the sex, nor the family status of smokers exerted a statistically significant affiliation with non-compliance. Higher rates of non-compliance were observed in restaurants, cafes, bars and nightclubs, common domestic premises of apartment buildings and indoor workplaces. Violations on public transport, in governmental buildings, health and sport facilities, colleges and universities were less common.

CONCLUSIONS

There is a need to revise the methods of enforcement with respect to sociodemographic characteristics of smokers associated with non-compliance in public places where violations are widespread.

Non-compliance and associated factors against smoke-free legislation among health care staffs in governmental hospitals in Addis Ababa, Ethiopia: an observational cross-sectional study

Background

In 2014, the Ethiopian government passed a new smoking legislation that banned smoking in public and workplaces including health care facilities. However, data’s on level of non-compliance and associated factors with non-compliance towards smoke-free legislation in hospital settings of the country has not been studied yet.

Methods

Hospital-based Cross-sectional study design triangulated with observational study was conducted in five hospitals. Data were collected through direct observation and interviews using checklist, structured and pre-tested questionnaires for observational study and survey of hospital employee respectively. Nine data collectors and one supervisor were involved in data collection. Three hundred fifty (350) health care staffs were interviewed. Fifteen (15) buildings were purposively observed for observational non-compliance in the selected hospitals. Data were entered by Epi Info and analyzed using SPSS version 21 software. Logistic regression was used to compute the crude and adjusted odds ratios for the factors affecting employee non-compliance with the legislation. A p-value of < 0.05 at 95% CI was considered to be statistically significant.

Results

Anti-smoking signs were absent from a high proportion of hospital areas (97% overall) although visible cigarette butts were generally not observed in most areas of the hospitals. Non-compliance level among health care staffs was 50(10.3%).Associated factors affecting to the non-compliance level of the staff were: being male (AOR = 5.89, p value = 0.001), having poor knowledge (AOR = 2.71, p-value = 0.022) and having Unfavorable attitudes (AOR = 6.15, p-value = 0.000).

Conclusions

Non-compliance level was high and needs careful implementation for 100% smoke-free legislation in addressing knowledge and attitudes of health care staffs.

Compliance with clinical guidelines and adherence to antiretroviral therapy among patients living with HIV

Objective: Evaluation of provider compliance with antiretroviral (ARV) treatment guidelines and patient adherence to ARVs is important for HIV care quality assessment; however, there are few current real-world data for guideline compliance and ARV adherence in the US. This study evaluated provider compliance with US Department of Health and Human Services (DHHS) guidelines and patient adherence to ARVs in a US population of patients with HIV.Methods: This was a retrospective claims study of adults with HIV-1 receiving ARV treatment between January 2010-December 2014. Follow-up began at first ARV treatment and ended at health plan disenrollment or study end. ARV regimens for treatment-naïve patients were categorized as "preferred/recommended", "alternative", or "non-preferred/recommended/alternative" according to DHHS guidelines. ARV adherence was evaluated using proportion of days covered (PDC) and medication possession ratio (MPR).Results: The analysis included 25,320 patients (84.4% male, mean age 45.3 years) and 39,071 regimens. Preferred/recommended regimens were most common during each study year, but the proportion of non-preferred/recommended/alternative regimens was substantial (15.9-20.6%). Only 53.6% of patients had optimal adherence by PDC ≥0.95, and 57.9% by MPR ≥0.95. Guideline non-compliance and sub-optimal adherence were more prevalent among female vs male patients (22.6% vs 14.8% [in 2014] and 65.9% vs 53.7%, respectively).Conclusions: Provider non-compliance with DHHS guidelines and sub-optimal ARV adherence among patients with HIV remain common in real-world practice, particularly for female patients. Healthcare providers should follow the latest clinical guidelines to ensure that patients receive recommended therapy, and address non-adherence when selecting ARV regimens.

Monte Carlo Simulations Demonstrate Algorithmic Interventions Over Time Reduce Hospitalisation in Patients With Schizophrenia and Bipolar Disorder

Non-adherence with pharmacologic treatment is associated with increased rates of relapse and rehospitalisation among patients with schizophrenia and bipolar disorder. To improve treatment response, remission, and recovery, research efforts are still needed to elucidate how to effectively map patient’s response to medication treatment including both therapeutic and adverse effects, compliance, and satisfaction in the prodromal phase of illness (ie, the time period in between direct clinical consultation and relapse). The Actionable Intime Insights (AI²) application draws information from Australian Medicare administrative claims records in real time when compliance with treatment does not meet best practice guidelines for managing chronic severe mental illness. Subsequently, the AI² application alerts clinicians and patients when patients do not adhere to guidelines for treatment. The aim of this study was to evaluate the impact of the AI² application on the risk of hospitalisation among simulated patients with schizophrenia and bipolar disorder. Monte Carlo simulation methodology was used to estimate the impact of the AI² intervention on the probability of hospitalisation over a 2-year period. Results indicated that when the AI² algorithmic intervention had an efficacy level of (>0.6), over 80% of actioned alerts were contributing to reduced hospitalisation risk among the simulated patients. Such findings indicate the potential utility of the AI² application should replication studies validate its methodologic and ecological rigour in real-world settings.

Analysis of randomised trials with long-term follow-up

Randomised trials with long-term follow-up can provide estimates of the long-term effects of health interventions. However, analysis of long-term outcomes in randomised trials may be complicated by problems with the administration of treatment such as non-adherence, treatment switching and co-intervention, and problems obtaining outcome measurements arising from loss to follow-up and death of participants. Methods for dealing with these issues that involve conditioning on post-randomisation variables are unsatisfactory because they may involve the comparison of non-exchangeable groups and generate estimates that do not have a valid causal interpretation. We describe approaches to analysis that potentially provide estimates of causal effects when such issues arise. Brief descriptions are provided of the use of instrumental variable and propensity score methods in trials with imperfect adherence, marginal structural models and g-estimation in trials with treatment switching, mixed longitudinal models and multiple imputation in trials with loss to follow-up, and a sensitivity analysis that can be used when trial follow-up is truncated by death or other events. Clinical trialists might consider these methods both at the design and analysis stages of randomised trials with long-term follow-up.

How do Parents Manage Irritability, Challenging Behaviour, Non-Compliance and Anxiety in Children with Autism Spectrum Disorders? A Meta-Synthesis

Although there is increasing research interest in the parenting of children with ASD, at present, little is known about everyday strategies used to manage problem behaviour. We conducted a meta-synthesis to explore what strategies parents use to manage irritability, non-compliance, challenging behaviour and anxiety in their children with ASD. Approaches included: (1) accommodating the child; (2) modifying the environment; (3) providing structure, routine and occupation; (4) supervision and monitoring; (5) managing non-compliance with everyday tasks; (6) responding to problem behaviour; (7) managing distress; (8) maintaining safety and (9) analysing and planning. Results suggest complex parenting demands in children with ASD and problem behaviour. Findings will inform the development of a new measure to quantify parenting strategies relevant to ASD.

Unilateral Muscle Artifacts due to Non-compliance During Uptake Phase of 18F-FDG PET/CT in an Oncologic Patient

A 49-year-old male patient with a prior history of poor compliance with medical appointments was referred for an ¹⁸F-fluoro-2-deoxy-D-glucose (¹⁸F-FDG) positron emission tomography/computed tomography (PET/CT) for the staging of a rectal squamous cell carcinoma. The PET/CT showed unilateral diffuse skeletal muscle ¹⁸F-FDG uptake as well as bilateral salivary gland uptake artifacts, suggestive of non-compliance with patient preparation instructions. The PET/CT nurse noted that during the ¹⁸F-FDG uptake phase, the patient appeared intoxicated, and she found two beer cans hidden in the waste disposal beside his chair just prior to imaging. The patient only admitted to eating a cookie approximately 30 minutes after the injection of ¹⁸F-FDG PET/CT and denied consuming alcohol during the uptake phase. We present the imaging findings of non-compliance with patient instructions during the uptake phase of ¹⁸F-FDG.

A framework for the design, conduct and interpretation of randomised controlled trials in the presence of treatment changes

Background

When a randomised trial is subject to deviations from randomised treatment, analysis according to intention-to-treat does not estimate two important quantities: relative treatment efficacy and effectiveness in a setting different from that in the trial. Even in trials of a predominantly pragmatic nature, there may be numerous reasons to consider the extent, and impact on analysis, of such deviations from protocol. Simple methods such as per-protocol or as-treated analyses, which exclude or censor patients on the basis of their adherence, usually introduce selection and confounding biases. However, there exist appropriate causal estimation methods which seek to overcome these inherent biases, but these methods remain relatively unfamiliar and are rarely implemented in trials.

Methods

This paper demonstrates when it may be of interest to look beyond intention-to-treat analysis for answers to alternative causal research questions through illustrative case studies. We seek to guide trialists on how to handle treatment changes in the design, conduct and planning the analysis of a trial; these changes may be planned or unplanned, and may or may not be permitted in the protocol. We highlight issues that must be considered at the trial planning stage relating to: the definition of nonadherence and the causal research question of interest, trial design, data collection, monitoring, statistical analysis and sample size.

Results and conclusions

During trial planning, trialists should define their causal research questions of interest, anticipate the likely extent of treatment changes and use these to inform trial design, including the extent of data collection and data monitoring. A series of concise recommendations is presented to guide trialists when considering undertaking causal analyses.

Factors Affecting Follow-Up Compliance in Patients After Endovascular Aneurysm Repair

OBJECTIVE

The purpose of this study was to evaluate potential factors affecting patient non-compliance after endovascular aneurysm repair.

METHOD

We performed a retrospective review of patients undergoing elective or emergency endovascular repair for thoracic, abdominal aorta, or iliac artery aneurysm at a single institution from November 2007 to March 2014. Compliance to follow-up at 1, 6, and 12 months was assessed. Factors evaluated included patient demographics, size of aneurysm, distance between the patient's residence and outpatient clinic, urgency of surgery, and time of year in which the follow-up visits were scheduled.

RESULTS

During the study period, 205 patients (75% male and 25% female) fulfilled the inclusion criteria. One-month mortality was 1.1% for elective procedures and 16.1% for emergency procedures (p = 0.001). Overall mortality at 12 months was 6.3% and 32.3% for elective and emergency procedures, respectively (p = 0.0002). Highest compliance was observed at 1 month, with 184 patients (93%) attending. A significant decrease was seen at 6 (n = 102, 54%) and 12 (n = 89, 48%) months. At the 12-month mark, a larger proportion of minority patients were non-compliant compared with Caucasian patients. Confounders for non-compliance were analyzed using multivariate analysis, and statistical significance was found for widowed marital status (p = 0.008), travel distance >25 miles to the outpatient clinic (p = 0.032), and emergency repair of aneurysms (p = 0.022).

CONCLUSION

Despite emphasizing the importance of follow-up after endovascular aortic procedures, almost half of the treated patients were non-compliant. Our study identified travel distance, marital status, and urgency of surgery as factors that may affect patients' compliance to scheduled follow-up visits.

Association between safety leading indicators and safety climate levels

OBJECTIVES

The aim of this study was to evaluate the association of leading indicators for occupational health and safety, particularly safety inspections and non-compliances, with safety climate levels.

METHODS

Nordic Occupational Safety Climate Assessment Questionnaire was employed to evaluate safety climate in cross-sectional design. The geographically diverse population of the inspection body made it possible to conduct the survey across 10 provinces in Iran. 89 completed questionnaires were obtained with a response rate of 47%. Except for management safety justice, the internal consistency of other six dimensions was found to be acceptable (α≥0.7).

RESULTS

Mean scores of dimensions ranged from 3.50 in trust in the efficacy of safety systems (SD=0.38) to 2.98 in workers' safety priority and risk non-acceptance (SD=0.47). Tukey HSD tests indicated a statistically significant difference of mean scores among groups undergoing different number of safety inspections and those receiving different number of non-compliances (p<0.05), with no significant differences based on safety training man-hours and sessions (p>0.05). Spearman's rank-order correlation showed no relationship between work experience and number of non-compliances (correlation coefficient=-0.04, p>0.05) and between safety training man-hours and number of non-compliances (correlation coefficient=-0.15, p>0.05).

CONCLUSIONS

Our results indicate that safety climate levels are influenced by number of safety inspections and the resultant non-compliances.

PRACTICAL APPLICATIONS

Findings suggest that safety non-compliances detected as a result of conducting safety inspections could be used to monitor the safety climate state. Establishing plans to conduct scheduled safety inspections and recording findings in the form of safety non-compliance and monitoring their trend could be used to monitor levels of safety climate.

Instrumental variable estimation of causal odds ratios using structural nested mean models

We consider estimating causal odds ratios using an instrumental variable under a logistic structural nested mean model (LSNMM). Current methods for LSNMMs either rely heavily on possible "uncongenial" modeling assumptions or involve intricate numerical challenges, which have impeded their use. In this article, we present an alternative method that ensures a congenial parametrization, circumvents computational complexity of existing methods, and is easy to implement. We illustrate the proposed method to (1) estimate the causal effect of years of education on earnings using data from the NLSYM and (2) assess the impact of moving families from high to low-poverty neighborhoods had on lifetime major depressive disorder among adolescents in the "Moving to Opportunity (MTO) for Fair Housing Demonstration Project" from the Department of Housing and Urban Development.

Passive leg raise testing effectively reduces fluid administration in septic shock after correction of non-compliance to test results

Background

Fluid resuscitation is considered a cornerstone of shock treatment, but recent data have underlined the potential hazards of fluid overload. The passive leg raise (PLR) test has been introduced as one of many strategies to predict ‘fluid responsiveness.’ The use of PLR testing is applicable to a wide range of clinical situations and has the potential to reduce fluid administration, since PLR testing is based upon (reversible) autotransfusion. Despite these theoretical advantages, data on the net effect on fluid balance as a result of PLR testing remain scarce.

Methods

We performed a prospective single-center multi-step interventional study in patients with septic shock to evaluate the effect of implementation of PLR testing on the fluid balance (FB) 48 hours after ICU admission. All patients were equipped with a PiCCO^® device for pulse contour analysis to guide fluid administration. An increase in stroke volume (SV) ≥ 10% was considered a positive test result.

Results

Before introduction of PLR testing, 21 patients were prospectively included in period 1 with a median FB of 4.8 [3.3–7.8]L. After an extensive training program, PLR testing was introduced and 20 patients were included in period 2. Median FB was 4.4 [3.3–7.5]L and did not differ from period 1 (p = 0.72). Further analysis revealed that non-compliance to the PLR test result was 44%. These findings were discussed with all ICU doctors and nurses. By consensus, non-compliance to the PLR test result was identified as the main reason for unsuccessful implementation of PLR testing. After this evaluation, 19 patients were included in period 3 under equal conditions as in period 2. In this period, median FB was 3.1 [1.5–4.9]L and significantly reduced in comparison with periods 1 and 2 (p = 0.016 and p = 0.023, respectively). Non-compliance was 9% and significantly lower than in period 2 (p = 0.009).

Conclusion

Implementation of PLR testing in patients with septic shock reduced fluid administration in the first 48 hours of ICU admission significantly and substantially. To achieve this endpoint, substantial non-compliance of ICU team members had to be addressed. Fluid administration despite a negative PLR test was the most common form of non-compliance.

Lay knowledge and management of malaria in Baringo county, Kenya

Background

Malaria, a disease caused by protozoan parasites of the genus Plasmodium and transmitted by female anopheline mosquitoes, is a major cause of morbidity, mortality and loss in productivity in humans. Baringo County is prone to seasonal transmissions of malaria mostly in the rainy seasons.

Methods

This cross-sectional study used a mixed methods approach to collect data on knowledge and lay management of malaria. A questionnaire survey was administered to 560 respondents while qualitative data was collected through 20 focus group discussions in four ecological zones covering Baringo North, Baringo South and Marigat sub-Counties of Baringo County. Analyses were done through summary and inferential statistics for quantitative data and content analysis for qualitative data.

Results

The study communities were knowledgeable of malaria signs, symptoms, cause and seasonality but this biomedical knowledge co-existed with other local perceptions. This knowledge, however, did not influence their first (p = 0.77) or second choice treatments (p = 0.49) and compliance to medication (p = 0.84). Up to 88 % of respondents reported having suffered from malaria. At the onset of a suspected malaria case community members reported the following: 28.9 % visited a health facility, 37.2 % used analgesics, 26.6 % herbal treatments, 2.2 % remnant malaria medicines, 2.2 % over the counter malaria medicines, 1 % traditional healers and 1.8 % other treatments. Nearly all respondents (97.8 %) reported visiting a health facility for subsequent treatments. Herbal treatments comprised of infusions and decoctions derived from roots, barks and leaves of plants believed to have medicinal value. Compliance to conventional malaria treatment regime was, however, identified as a challenge in malaria management. Quick relief from symptoms, undesirable qualities like drug bitterness and bad smell, undesirable side-effects, such as nausea and long regimen of treatment were some of the contributors to non-compliance. Men and women exhibited different health-seeking behaviours based on the cultural expectations of masculinity, femininity, gender roles and acceptability of health services.

Conclusions

While knowledge of malaria is important in identifying the disease, it does not necessarily lead to good management practice. Treatment-seeking behaviour is also influenced by perceived cause, severity of disease, timing, anticipated cost of seeking treatment and gender, besides the availability of both traditional and conventional medicines.

Evidence-based practice and barriers to compliance: Face bow transfer

PURPOSE

To recapitulate a 2003 study inquiring of US dental schools whether they teach the face bow transfer by means of a survey in order to determine if compliance with clinical evidence has improved.

METHODS

The same 54 dental schools surveyed in 2003 were asked the same question regarding whether they teach the use of the face bow transfer in the complete denture curriculum.

RESULTS

Teaching of the face bow transfer has increased in prevalence from 84% of surveyed schools in 2003 to 93.75% of surveyed schools in 2015.

CONCLUSIONS

This finding is especially interesting in light of the fact that there is no compelling evidence supporting the use of the face bow transfer with regard to improving patient outcomes. With respect to the continued unjustified teaching of the face bow transfer, some possible reasons for non-compliance with best available evidence are presented using the medical literature for reference.

Comparative evaluation of molar distalization therapy using pendulum and distal screw appliances

OBJECTIVE

To compare dentoalveolar and skeletal changes produced by the pendulum appliance (PA) and the distal screw appliance (DS) in Class II patients.

METHODS

Forty-three patients (19 men, 24 women) with Class II malocclusion were retrospectively selected for the study. Twenty-four patients (mean age, 12.2 ± 1.5 years) were treated with the PA, and 19 patients (mean age, 11.3 ± 1.9 years) were treated with the DS. The mean distalization time was 7 months for the PA group and 9 months for the DS group. Lateral cephalograms were obtained at T1, before treatment, and at T2, the end of distalization. A Mann-Whitney U test was used for statistical comparisons of the two groups between T1 and T2.

RESULTS

PA and DS were equally effective in distalizing maxillary molars (4.7 mm and 4.2 mm, respectively) between T1 and T2; however, the maxillary first molars showed less distal tipping in the DS group than in the PA group (3.2° vs. 9.0°, respectively). Moreover, significant premolar anchorage loss (2.7 mm) and incisor proclination (5.0°) were noted in the PA group, whereas premolar distal movement (1.9 mm) and no significant changes at the incisor (0.1°) were observed in the DS group. No significant sagittal or vertical skeletal changes were detected between the two groups during the distalization phase.

CONCLUSIONS

PA and DS seem to be equally effective in distalizing maxillary molars; however, greater distal molar tipping and premolar anchorage loss can be expected using PA.

Clinical Profile of Diabetic Ketoacidosis: A Prospective Study in a Tertiary Care Hospital

BACKGROUND

Diabetic ketoacidosis, a well-known and major acute metabolic complication classically occurs in young patients with type 1 diabetes. However, it may occur in patients with type 2 Diabetes Mellitus too.

OBJECTIVE

Aim of this study was to look into the clinical profile, precipitating factors and clinical outcome in the patients presenting with Diabetic ketoacidosis in the Emergency of a Tertiary care hospital.

DESIGN

The study was a prospective study conducted over a period of two years in Kasturba Medical College, Manipal Karnataka, India.

MATERIALS AND METHODS

Clinical profile of 60 diabetic patients admitted in the Emergency with the diagnosis of Diabetic ketoacidosis were analysed.

RESULTS

Out of 60 patients, 12 were of Type 1 and 48 were Type 2 Diabetes Mellitus. Mean duration of diabetes was 8.65 years. Only 14 (23.3%) patients were taking regular treatment for Diabetes Mellitus whereas 32 (53.33%) patients were on irregular treatment and eight (13.33%) were not on any treatment at all. Among 12 Type 1 Diabetic patients, six patients were freshly diagnosed to be diabetic when they presented with Diabetic ketoacidosis complication. Nausea and vomiting (63.33%) were the most common symptoms of these patients. Infections (73.33%) were the most common precipitating factor for Diabetic ketoacidosis. Mean fluid requirement on first day of therapy was 3.51 liters. Mortality of 10% was seen.

CONCLUSION

Diabetic ketoacidosis is a fatal acute metabolic complication of Diabetes Mellitus with heterogeneous clinical presentation. Early diagnosis and treatment can avoid morbidity & mortality.

Blending Stimulus Fading Procedures with Forward Chaining to Address Treatment Resistance in an Adult with an Autism Spectrum Disorder

The following paper details the implementation of a program to address the high-risk physical aggression and property destruction behavior of an adult male with an autism spectrum disorder (ASD) and severe aggressive behavior. A task analysis (TA) and forward chaining were combined with a stimulus fading procedure to allow the subject to be able to participate in van rides when prompted with no displays of aggressive or self-injurious behavior. A follow-up probe completed at 1-year post intervention demonstrated the maintenance of the gains that were made during treatment.

Towards changing healthcare workers' behaviour: a qualitative study exploring non-compliance through appraisals of infection prevention and control practices

BACKGROUND

Improving behaviour in infection prevention and control (IPC) practice remains a challenge, and understanding the determinants of healthcare workers' (HCWs) behaviour is fundamental to develop effective and sustained behaviour change interventions.

AIM

To identify behaviours of HCWs that facilitated non-compliance with IPC practices, focusing on how appraisals of IPC duties and social and environmental circumstances shaped and influenced non-compliant behaviour. This study aimed to: (1) identify how HCWs rationalized their own behaviour and the behaviour of others; (2) highlight challenging areas of IPC compliance; and (3) describe the context of the working environment that may explain inconsistencies in IPC practices.

METHODS

Clinical staff at a National Health Service hospital group in London, UK were interviewed between December 2010 and July 2011 using qualitative methods. Responses were analysed using a thematic framework.

FINDINGS

Three ways in which HCWs appraised their behaviour were identified through accounts of IPC policies and practices: (1) attribution of responsibilities, with ambiguity about responsibility for certain IPC practices; (2) prioritization and risk appraisal, which demonstrated a divergence in values attached to some IPC policies and practices; and (3) hierarchy of influence highlighted that traditional clinical roles challenged work relationships.

CONCLUSIONS

Overall, behaviours are not entirely independent of policy rules, but often an amalgamation of local normative practices, individual preferences and a degree of professional isolation.

Evaluation of Factors in Relation with the Non-Compliance to Curative Intent Radiotherapy among Patients of Head and Neck Carcinoma: A Study from the Kumaon Region of India

INTRODUCTION

Radiotherapy (RT)-based curative regimens for head and neck squamous cell carcinomas (HNSCC) deliver a dose of 66-70 Gray (Gy) over a period of 6-7 weeks, and incomplete treatments are unlikely to result in cure. Non-compliance to RT is major contributory factor to treatment failure.

AIMS

To assess the proportion of patients who do not complete planned treatment after initiation of curative RT. This study also aims to explore a possible relationship of non-compliance due to socio-economic, disease-related and treatment-related factors.

MATERIALS AND METHODS

The records of HNSCC patients treated from January 2012-December 2013 were audited. Data from the treatment records were to collect patient-related, disease-related, and social demographic parameters. Of the patients who had not completed treatment, the reasons behind the same were investigated.

RESULTS

Of the 324 patients of HNSCC who were initiated on radical RT, a total of 76 patients were found to have discontinued treatment without authorization of the treating clinician. There was no significant predilection for treatment non-compliance with regards to patient age, educational status, religion, site of the disease, use of neoadjuvant chemotherapy, or use of concurrent chemotherapy. There tended to be a higher association of treatment non-compliance among patients residing >100 km away from the treatment center, patients hailing from hilly regions, patients without the below poverty line (BPL) card, unemployed patients, and patients with stage IV-A/B disease. Of the 76 patients who did not complete treatment, telephonic questionnaire could be obtained from 54 patients. Causes for non-compliance included preference for traditional healers (22.2%), fear of toxicity (7.4%), logistic reasons (18.5%), financial reasons (24.1%), and lack of interest/faith in RT (5.6%).

CONCLUSION

There is a high incidence of treatment default among patients of HNSCC during RT in this region. The revelation of the higher propensity for treatment default among patients from distant, hilly regions, unemployed, patients without BPL cards, and stages-IVA/IVB highlights the need for specific interventions for these special populations.

Association between number of doses per day, number of medications and patient's non-compliance, and frequency of readmissions in a multi-ethnic Asian population

Objective

To investigate whether number of doses per day and number of medications are significantly associated with the number of readmissions and to study the association of readmission frequency with other medical and socio-demographic variables.

Methods

Retrospective cross-sectional study involving 432 patients who were readmitted within 15 days of previous hospital discharge between January 1, 2013 and March 31, 2013. Relevant medical records were collected from the national electronic databases of every public tertiary hospital in Singapore. Significant variables (p < 0.05) were identified using forward selection and modeled using generalized linear mixed models.

Results

A total of 649 unplanned readmissions were reviewed. At a multivariable level, number of readmission was significantly associated with the number of medications (p = 0.002) and number of doses per day (p = 0.003) after adjusting for race, liver disease, schizophrenia and non-compliance.

Conclusion

Complex medication regimen (i.e. multiple medications and multiple doses per day) is a statistically significant predictor of number of readmissions. Simplifying therapeutic regimens with alternatives such as longer-acting or fixed-dose combination drugs may facilitate better patient adherence and reduce costly readmissions.

•

Patient's non-compliance can increase risk of unplanned readmissions.

•

The number of doses per day is a positive predictor of unplanned readmissions.

•

Higher number of medications is associated with more frequent readmissions.

Comparative evaluation of molar distalization therapy with erupted second molar: Segmented versus Quad Pendulum appliance

Background

There are controversial opinions about the effect of erupted second molars on distalization of the first molars. Most of the distalizing devices are anchored on the first molars, without including second molars; so, differences between sequentially distalize maxillary molars (second molar followed by the first molar) or distalize second and first molars together are not clear. The aim of the study was to compare sequential versus simultaneous molar distalization therapy with erupted second molar using two different modified Pendulum appliances followed by fixed appliances.

Methods

The treatment sample consisted of 35 class II malocclusion subjects, divided in two groups: group 1 consisted of 24 patients (13 males and 11 females) with a mean pre-treatment age of 12.9 years, treated with the Segmented Pendulum (SP) and fixed appliances; group 2 consisted of 11 patients (6 males and 5 females) with a mean pre-treatment age of 13.2 years, treated with the Quad Pendulum (QP) and fixed appliances. Lateral cephalograms were obtained before treatment (T1), at the end of distalization (T2), and at the end of orthodontic fixed appliance therapy (T3). A Student t test was used to identify significant between-group differences between T1 to T2, T2 to T3, and T1 to T3.

Results

QP and SP were equally effective in distalizing maxillary molars (3.5 and 4 mm, respectively) between T1 and T2; however, the maxillary first molar showed less distal tipping (4.6° vs. 9.6°) and more extrusion (1.1 vs. 0.2 mm) in the QP group than in the SP group, as well as the vertical facial dimension, which increased more in the QP group (1.2°) than in the SP group (0.7°). At T3, the QP group maintained greater increase in lower anterior facial height and molar extrusion and decrease in overbite than the SP group.

Conclusion

Quad Pendulum seems to have greater increase in vertical dimension and molar extrusion than the Segmented Pendulum.
