Patient and family engagement in incident investigations: exploring hospital manager and incident investigators’ experiences and challenges
Objective: There is growing recognition among health care providers and policy makers that when things go wrong, the patient or their families should be heard and participate in the incident investigation process. This paper explores how Dutch hospitals organize patient or family engagement in incident investigations, maps out incident investigators’ experiences of involving patients or their families in incident investigations and identifies the challenges encountered. Methods: Semi-structured interviews were conducted with managers and incident investigators in 13 Dutch hospitals. Study participants (n = 18) were asked about the incident investigation routines and their experiences of involving affected patients or family members. Interview transcripts were coded and analysed using thematic content analysis. Results: Our findings reveal that patient or family involvement in incident investigations is typically organized as a one-time interview event. Interviews with patients or their families were considered to be valuable and important in their own right and seen as a way to do justice to the individual needs of the patient or their family. Yet, the usefulness and validity of the patient or family perspective for incident investigations was often seen to be limited, with the professional perspective afforded more weight. This was particularly the case when the patient or their family were unable to provide verifiable details of the incident under investigation. Study participants described challenges when involving patients or family members, including in relation to the available timeframe for incident investigations, legal issues, managing trust and working with intense emotions. Conclusions: We propose that by placing patient and family criteria of significance at the centre of incident investigations (i.e. an ‘emic’ research approach), hospitals may be able to expand their learning potential and improve patient-centeredness following an incident
The doctor was rude, the toilets are dirty
Modern healthcare systems are highly data- and evidence-driven. The use of indicators and other performance management devices, introduced by healthcare leaders and regulators to monitor performance and address patient safety matters, are just two examples. Research has shown that the wish to manage and address risks via measuring practices does not always do justice to the complexities of healthcare organization and delivery, for (patient) safety and quality are not only about measurable things. So, while recognized as valuable, there are calls that hard metrics must be supplemented with soft signals – generally known as qualitative or informal data – to gain a better representation of actual performance and tackle safety issues. With the aim to contribute to the theoretical notion that a dialogical approach to knowledge and information-management is a fruitful way to manage and address risks and problems in healthcare, this paper addresses the research question ‘What role do soft signals play in the assessment of patient safety risks and how are these signals employed in everyday regulatory practices?’ We draw from qualitative interviews, observations and document analyses in a multi-year (2015-2019) research project to show that soft signals are vital to everyday regulatory practices, as they provide context to ‘hard’ signals and help to make sense of and weigh risks. Based on these findings we encourage policy makers and regulatory bodies to start an active dialogue on their use of soft signals and develop work models and working routines for discussing them as well as their implications
Male tobacco smoke load and non-lung cancer mortality associations in Massachusetts
<p>Abstract</p> <p>Background</p> <p>Different methods exist to estimate smoking attributable cancer mortality rates (Peto and Ezzati methods, as examples). However, the smoking attributable estimates using these methods cannot be generalized to all population sub-groups. A simpler method has recently been developed that can be adapted and applied to different population sub-groups. This study assessed cumulative tobacco smoke damage (smoke load)/non-lung cancer mortality associations across time from 1979 to 2003 among all Massachusetts males and ages 30–74 years, using this novel methodology.</p> <p>Methods</p> <p>Annual lung cancer death rates were used as smoke load bio-indices, and age-adjusted lung/all other (non-lung) cancer death rates were analyzed with linear regression approach. Non-lung cancer death rates include all cancer deaths excluding lung. Smoking-attributable-fractions (SAFs) for the latest period (year 2003) were estimated as: 1-(estimated unexposed cancer death rate/observed rate).</p> <p>Results</p> <p>Male lung and non-lung cancer death rates have declined steadily since 1992. Lung and non-lung cancer death rates were tightly and steeply associated across years. The slopes of the associations analyzed were 1.69 (95% confidence interval (CI) 1.35–2.04, r = 0.90), and 1.36 (CI 1.14–1.58, r = 0.94) without detected autocorrelation (Durbin-Watson statistic = 1.8). The lung/non-lung cancer death rate associations suggest that all-sites cancer death rate SAFs in year 2003 were 73% (Sensitivity Range [SR] 61–82%) for all ages and 74% (SR 61–82%) for ages 30–74 years.</p> <p>Conclusion</p> <p>The strong lung/non-lung cancer death rate associations suggest that tobacco smoke load may be responsible for most prematurely fatal cancers at both lung and non-lung sites. The present method estimates are greater than the earlier estimates. Therefore, tobacco control may reduce cancer death rates more than previously noted.</p
Involving patients and families in the analysis of suicides, suicide attempts, and other sentinel events in mental healthcare: A qualitative study in The Netherlands
Involving patients and families in mental healthcare is becoming more commonplace, but little is known about how they are involved in the aftermath of serious adverse events related to quality of care (sentinel events, including suicides). This study explores the role patients and families have in formal processes after sentinel events in Dutch mental healthcare. We analyzed the existing policies of 15 healthcare organizations and spoke with 35 stakeholders including patients, families, their counselors, the national regulator, and professionals. Respondents argue that involving patients and families is valuable to help deal with the event emotionally, provide additional information, and prevent escalation. Results indicate that involving patients and families is only described in sentinel event policies to a limited extent. In practice, involvement consists mostly of providing aftercare and sharing information about the event by providers. Complexities such as privacy concerns and involuntary admissions are said to hinder involvement. Respondents also emphasize that involvement should not be obligatory and stress the need for patients and families to be involved throughout the process of treatment. There is no one-size-fits-all strategy for involving patients and families after sentinel events. The first step seems to be early involvement during treatment process itself
Publication of inspection frameworks: a qualitative study exploring the impact on quality improvement and regulation in three healthcare settings
Background: The Dutch healthcare inspectorate publishes its inspection frameworks to inform both the public and healthcare providers about regulatory procedures and in the hope that publication will motivate healthcare providers to improve quality and comply with standards. This study explores the consequences of publishing these frameworks for the regulation of quality and safety in healthcare. Methods: We selected recently published inspection frameworks used in three healthcare settings: nursing home care, dental care and hospital care. We conducted 37 interviews with 39 respondents (healthcare professionals, managers, quality officers, policy advisers and inspectors) and explored their awareness of and experiences with these frameworks. We held a group interview with three inspectors to reflect on our findings. All data underwent thematic content analysis. Results: We found that the institutional infrastructure of a sector plays an important role in how an inspection framework is used after publication; particularly the presence and maturity of quality improvement work in the sector and the inspectorate's grip on a sector matter. Respondents mentioned differences in framework use in organisational contexts, particularly relating to scale. In some organisations, the framework served as an accountability mechanism to check if quality meets basic standards, while in other organisations professionals adopted it to stimulate discussion and learning across teams. Conclusion: Publication of inspection frameworks might result in quality improvement work, and in particular contexts could be used as a regulatory strategy to target quality improvement in a healthcare sector. For this, it is important that regulators consider the capabilities and possibilities for learning an
Mycobacterium tuberculosis Phosphate Uptake System Component PstA2 Is Not Required for Gene Regulation or Virulence
The Mycobacterium tuberculosis genome encodes two complete high-affinity Pst phosphate-specific transporters. We previously demonstrated that a membrane-spanning component of one Pst system, PstA1, was essential both for M. tuberculosis virulence and for regulation of gene expression in response to external phosphate availability. To determine if the alternative Pst system is similarly required for virulence or gene regulation, we constructed a deletion of pstA2. Transcriptome analysis revealed that PstA2 is not required for regulation of gene expression in phosphate-replete growth conditions. PstA2 was also dispensable for replication and virulence of M. tuberculosis in a mouse aerosol infection model. However, a Delta pstA1 Delta pstA2 double mutant was attenuated in mice lacking the cytokine interferon-gamma, suggesting that M. tuberculosis requires high-affinity phosphate transport to survive phosphate limitation encountered in the host. Surprisingly, Delta pstA2 bacteria were more resistant to acid stress in vitro. This phenotype is intrinsic to the alternative Pst transporter since a Delta pstS1 mutant exhibited similar acid resistance. Our data indicate that the two M. tuberculosis Pst transporters have distinct physiological functions, with the PstA1 transporter being specifically involved in phosphate sensing and gene regulation while the PstA2 transporter influences survival in acidic conditions
Analysis of host responses to Mycobacterium tuberculosis antigens in a multi-site study of subjects with different TB and HIV infection states in sub-Saharan Africa.
BACKGROUND: Tuberculosis (TB) remains a global health threat with 9 million new cases and 1.4 million deaths per year. In order to develop a protective vaccine, we need to define the antigens expressed by Mycobacterium tuberculosis (Mtb), which are relevant to protective immunity in high-endemic areas. METHODS: We analysed responses to 23 Mtb antigens in a total of 1247 subjects with different HIV and TB status across 5 geographically diverse sites in Africa (South Africa, The Gambia, Ethiopia, Malawi and Uganda). We used a 7-day whole blood assay followed by IFN-γ ELISA on the supernatants. Antigens included PPD, ESAT-6 and Ag85B (dominant antigens) together with novel resuscitation-promoting factors (rpf), reactivation proteins, latency (Mtb DosR regulon-encoded) antigens, starvation-induced antigens and secreted antigens. RESULTS: There was variation between sites in responses to the antigens, presumably due to underlying genetic and environmental differences. When results from all sites were combined, HIV- subjects with active TB showed significantly lower responses compared to both TST(-) and TST(+) contacts to latency antigens (Rv0569, Rv1733, Rv1735, Rv1737) and the rpf Rv0867; whilst responses to ESAT-6/CFP-10 fusion protein (EC), PPD, Rv2029, TB10.3, and TB10.4 were significantly higher in TST(+) contacts (LTBI) compared to TB and TST(-) contacts fewer differences were seen in subjects with HIV co-infection, with responses to the mitogen PHA significantly lower in subjects with active TB compared to those with LTBI and no difference with any antigen. CONCLUSIONS: Our multi-site study design for testing novel Mtb antigens revealed promising antigens for future vaccine development. The IFN-γ ELISA is a cheap and useful tool for screening potential antigenicity in subjects with different ethnic backgrounds and across a spectrum of TB and HIV infection states. Analysis of cytokines other than IFN-γ is currently on-going to determine correlates of protection, which may be useful for vaccine efficacy trials
Angular redistribution of near-infrared emission from quantum dots in 3D photonic crystals
We study the angle-resolved spontaneous emission of near-infrared light
sources in 3D photonic crystals over a wavelength range from 1200 to 1550 nm.
To this end PbSe quantum dots are used as light sources inside titania inverse
opal photonic crystals. Strong deviations from the Lambertian emission profile
are observed. An attenuation of 60 % is observed in the angle dependent radiant
flux emitted from the samples due to photonic stop bands. At angles that
correspond to the edges of the stop band the emitted flux is increased by up to
34 %. This increase is explained by the redistribution of Bragg-diffracted
light over the available escape angles. The results are quantitatively
explained by an expanded escape-function model. This model is based on
diffusion theory and adapted to photonic crystals using band structure
calculations. Our results are the first angular redistributions and escape
functions measured at near-infrared, including telecom, wavelengths. In
addition, this is the first time for this model to be applied to describe
emission from samples that are optically thick for the excitation light and
relatively thin for the photoluminesence light.Comment: 24 pages, 8 figures (current format = single column, double spaced
The incidence of experimental smoking in school children: an 8-year follow-up of the child and adolescent behaviors in long-term evolution (CABLE) study
<p>Abstract</p> <p>Background</p> <p>Studies have established that most regular adult smokers become addicted in their adolescent years. We investigated the incidence of and risk factors associated with initial experimental smoking among a group of school children who were followed for 8 years.</p> <p>Methods</p> <p>We used cohort data collected as part of the Child and Adolescent Behaviors in Long-term Evolution (CABLE) study, which selected nine elementary schools each from an urban area (Taipei City) and a rural area (Hsingchu county) in northern Taiwan. From 2002 to 2008, children were asked annually whether they had smoked in the previous year. An accelerated lifetime model with Weibull distribution was used to examine the factors associated with experimental smoking.</p> <p>Results</p> <p>In 2001, 2686 4<sup>th</sup>-graders participated in the study. For each year from 2002 to 2008, their incidences of trial smoking were 3.1%, 4.0%, 2.8%, 6.0%, 5.3%, 5.0% and 6.0%, respectively. There was an increase from 7<sup>th </sup>to 8<sup>th </sup>grade (6.0%). Children who were males, lived in rural areas, came from single-parent families, had parents who smoked, and had peers who smoked were more likely to try smoking earlier. The influence of parents and peers on experimental smoking demonstrated gradient effects.</p> <p>Conclusions</p> <p>This study used a cohort to examine incidence and multiple influences, including individual factors, familial factors, and community factors, on experimental smoking in adolescents. The findings fit the social ecological model, highlighting the influences of family and friends. School and community attachment were associated with experimental smoking in teenagers.</p
