Comparative efficacy of two interventions to discontinue long-term benzodiazepine use: cluster randomised controlled trial in primary care.

BACKGROUND: Benzodiazepines are extensively used in primary care, but their long-term use is associated with adverse health outcomes and dependence. AIMS: To analyse the efficacy of two structured interventions in primary care to enable patients to discontinue long-term benzodiazepine use. METHOD: A multicentre three-arm cluster randomised controlled trial was conducted, with randomisation at general practitioner level (trial registration ISRCTN13024375). A total of 532 patients taking benzodiazepines for at least 6 months participated. After all patients were included, general practitioners were randomly allocated (1:1:1) to usual care, a structured intervention with follow-up visits (SIF) or a structured intervention with written instructions (SIW). The primary end-point was the last month self-declared benzodiazepine discontinuation confirmed by prescription claims at 12 months. RESULTS: At 12 months, 76 of 168 (45%) patients in the SIW group and 86 of 191 (45%) in the SIF group had discontinued benzodiazepine use compared with 26 of 173 (15%) in the control group. After adjusting by cluster, the relative risks for benzodiazepine discontinuation were 3.01 (95% CI 2.03-4.46, P<0.0001) in the SIW and 3.00 (95% CI 2.04-4.40, P<0.0001) in the SIF group. The most frequently reported withdrawal symptoms were insomnia, anxiety and irritability. CONCLUSIONS: Both interventions led to significant reductions in long-term benzodiazepine use in patients without severe comorbidity. A structured intervention with a written individualised stepped-dose reduction is less time-consuming and as effective in primary care as a more complex intervention involving follow-up visits.

Mental impact of Covid-19 among Spanish healthcare workers. A large longitudinal survey.

AIMS: Longitudinal data on the mental health impact of the coronavirus disease 2019 (Covid-19) pandemic in healthcare workers is limited. We estimated prevalence, incidence and persistence of probable mental disorders in a cohort of Spanish healthcare workers (Covid-19 waves 1 and 2) -and identified associated risk factors. METHODS: 8996 healthcare workers evaluated on 5 May-7 September 2020 (baseline) were invited to a second web-based survey (October-December 2020). Major depressive disorder (PHQ-8 ≥ 10), generalised anxiety disorder (GAD-7 ≥ 10), panic attacks, post-traumatic stress disorder (PCL-5 ≥ 7), and alcohol use disorder (CAGE-AID ≥ 2) were assessed. Distal (pre-pandemic) and proximal (pandemic) risk factors were included. We estimated the incidence of probable mental disorders (among those without disorders at baseline) and persistence (among those with disorders at baseline). Logistic regression of individual-level [odds ratios (OR)] and population-level (population attributable risk proportions) associations were estimated, adjusting by all distal risk factors, health care centre and time of baseline interview. RESULTS: 4809 healthcare workers participated at four months follow-up (cooperation rate = 65.7%; mean = 120 days s.d. = 22 days from baseline assessment). Follow-up prevalence of any disorder was 41.5%, (v. 45.4% at baseline, p < 0.001); incidence, 19.7% (s.e. = 1.6) and persistence, 67.7% (s.e. = 2.3). Proximal factors showing significant bivariate-adjusted associations with incidence included: work-related factors [prioritising Covid-19 patients (OR = 1.62)], stress factors [personal health-related stress (OR = 1.61)], interpersonal stress (OR = 1.53) and financial factors [significant income loss (OR = 1.37)]. Risk factors associated with persistence were largely similar. CONCLUSIONS: Our study indicates that the prevalence of probable mental disorders among Spanish healthcare workers during the second wave of the Covid-19 pandemic was similarly high to that after the first wave. This was in good part due to the persistence of mental disorders detected at the baseline, but with a relevant incidence of about 1 in 5 of HCWs without mental disorders during the first wave of the Covid-19 pandemic. Health-related factors, work-related factors and interpersonal stress are important risks of persistence of mental disorders and of incidence of mental disorders. Adequately addressing these factors might have prevented a considerable amount of mental health impact of the pandemic among this vulnerable population. Addressing health-related stress, work-related factors and interpersonal stress might reduce the prevalence of these disorders substantially. Study registration number: NCT04556565.

Four-month incidence of suicidal thoughts and behaviors among healthcare workers after the first wave of the Spain COVID-19 pandemic.

Healthcare workers (HCW) are at high risk for suicide, yet little is known about the onset of suicidal thoughts and behaviors (STB) in this important segment of the population in conjunction with the COVID-19 pandemic. We conducted a multicenter, prospective cohort study of Spanish HCW active during the COVID-9 pandemic. A total of n = 4809 HCW participated at baseline (May-September 2020; i.e., just after the first wave of the pandemic) and at a four-month follow-up assessment (October-December 2020) using web-based surveys. Logistic regression assessed the individual- and population-level associations of separate proximal (pandemic) risk factors with four-month STB incidence (i.e., 30-day STB among HCW negative for 30-day STB at baseline), each time adjusting for distal (pre-pandemic) factors. STB incidence was estimated at 4.2% (SE = 0.5; n = 1 suicide attempt). Adjusted for distal factors, proximal risk factors most strongly associated with STB incidence were various sources of interpersonal stress (scaled 0-4; odds ratio [OR] range = 1.23-1.57) followed by personal health-related stress and stress related to the health of loved ones (scaled 0-4; OR range 1.30-1.32), and the perceived lack of healthcare center preparedness (scaled 0-4; OR = 1.34). Population-attributable risk proportions for these proximal risk factors were in the range 45.3-57.6%. Other significant risk factors were financial stressors (OR range 1.26-1.81), isolation/quarantine due to COVID-19 (OR = 1.53) and having changed to a specific COVID-19 related work location (OR = 1.72). Among other interventions, our findings call for healthcare systems to implement adequate conflict communication and resolution strategies and to improve family-work balance embedded in organizational justice strategies.

Satisfaction with and psychological impact of immediate and deferred breast reconstruction.

BACKGROUND: The present work assesses the effect of immediate breast reconstruction (IBR), deferred breast reconstruction (DBR), and no breast reconstruction on the psychological impact. PATIENTS AND METHODS: Standard questionnaires were used to determine the psychological impact suffered by patients who underwent IBR, DBR and no reconstruction, their degree of satisfaction with the results achieved, and their postprocedure opinions regarding reconstruction options. RESULTS: A total of 526 women underwent mastectomy. The response rate to the questionnaires was 71.67%. A significantly greater proportion of the women who underwent no reconstruction suffered psychological problems than those who underwent reconstruction of some type (P = 0.01). Some 94.77% of the women who underwent IBR maintained a postprocedure preference for this option; in contrast, some 87.27% of the DBR and 56.14% of the no-reconstruction patients declared a postprocedure preference for IBR. In all, 63.49% of the women who underwent reconstruction were moderately very satisfied with the aesthetic results achieved, while only 22.80% of the no-reconstruction patients declared such satisfaction (P = 0.0001). CONCLUSIONS: The women who underwent no breast reconstruction suffered more emotional problems than those who underwent a reconstruction procedure. In general, all groups reported a postprocedure preference for IBR in their questionnaire answers. The aesthetic results achieved by IBR seem to be those best accepted.

[Epidemiologic surveillance of hospital infection. Preliminary analysis of a 5-year series]. / Vigilancia epidemiológica de la infección hospitalaria. Análisis preliminar de una serie de cinco años.

The epidemiological surveillance provides opportunities to know the magnitude and determinants of nosocomial infection and permits, at the same time, the planning, implementation and evaluation of prevention and treatment activities in order to approach the rates of infection in the hospital, as near as possible, to the irreducible minimum. We show data collected by surveillance system Guadalajara General Hospital from 1982 to 1987. In order to analyze general trends, seasonality, accidental variations and endemic levels, we have used statistical methods as linear regression, chi 2, equality proportions and built of an endemic channel with confidence intervals of 95%. We have observed a decreasing trend, locating endemic levels around to 4% of monthly accumulated incidence. There is a possible seasonal influence concurring with holidays periods and someone accidental variation over that we expected, it was related with a deteriorated situation about medical care.

[Relationship between nosocomial infection and hospital mortality. Multicenter study]. / Relación de la infección nosocomial con la mortalidad hospitalaria. Estudio multicéntrico.

BACKGROUND: Hospital mortality related to infections acquired in the hospital setting has not been well studied in Spain. We carried out a study of seven hospitals in order to assess and quantify the problem. METHODS: The study period included three months of observations (between November 1, 1989 and January 31, 1990), and data pertaining to all deaths of patients hospitalized for a minimum of 24 hours were collected. The number of people admitted within the study period was 16,025, and the number of deaths registered and included in our study was 488 (3%). The data were obtained from the patient's medical history one week after death as well as from the hospital physicians on the case. In order to quantify the interobserver variability derived from the classification criteria, the simple kappa index was calculated and averaged to form an ordinal scale. RESULTS: 216 (44.3%) of 488 deaths included in our study had no infection, 138 (28%) had an infection no-hospital-associated, and 134 (27%) had nosocomial infection (50-10%--"causally related to death", 59-12%--"contributing to death", and 25-5%--"not related to death"). The lower respiratory tract infections, bacteremias and surgical wound infections were the most related to cause of death. Staphylococcus aureus was the pathogen most frequently associated with the infections found at the time of death. CONCLUSIONS: Those patients admitted with non-fatal diseases made up the greatest percentage (39.9%) of deaths from nosocomial infections. The infection was considered the direct cause of death in 18.8% of these cases, although the differences found had no statistical significance.

Cost of borderline personality disorder in Catalonia (Spain).

INTRODUCTION: The available information on the cost of illness of Borderline Personality Disorder (BPD) is overtly insufficient for policy planning. Our aim was to estimate the costs of illness for BPD in Catalonia (Spain) for 2006. METHODS: This is a multilevel cross-design synthesis study combining a qualitative nominal approach, quantitative 'top-down' analysis of multiple health databases, and 'bottom-up' data of local surveys. Both direct and indirect costs have been estimated from a governmental and societal perspective. RESULTS: Estimated year-prevalence of BPD was 0.7% (41,921 cases), but only 9.6% of these cases were treated in the mental health system (4033 cases). The baseline of the total cost of BPD in Catalonia was 45.6 million€, of which 15.8 million€ (34.7%) were direct costs related to mental health care. The cost distribution was 0.4% in primary care; 4% in outpatient mental health care; 4.7% in hospitalisation; 0.7% in emergency care; and 24.9% in pharmacotherapy. Additionally, the cost of drug addiction treatment for persons with BPD was 11.2%; costs associated with sheltered employment were 23.9% and those of crime and justice were 9.7%. Indirect costs - including temporary sick leave and premature death (suicide) - represented 20.5% of total costs. The average annual cost per patient was 11,308€. CONCLUSIONS: An under-reporting of BPD was identified by the experts in all health databases and official registries. Most of the BPD costs were not related to mental health care. Amongst the direct cost categories, pharmacotherapy had the largest proportion despite the lack of specificity for BPD. This distribution of costs reinforces the idea of BPD complexity related to an inadequate and inefficient use of health resources.

Determination of chloride concentration in cheese: collaborative study.

Three samples of ground Gouda cheese containing 1-2% chloride were analyzed by 7 laboratories by 3 methods: oxidation with KMnO4 and HNO3 followed by a Volhard titration; the same but with filtering off the precipitated AgC1 before back-titration; and the general potentiometric method without ashing or oxidation. The data were analyzed by ISO statistics (ISO-R 5725) and by AOAC statistics (Youden), the major differences being the rejection of different values as outliers and in the statement of the precision parameters. The within-laboratory variability (repeatability) is comparable for all 3 methods; the between-laboratory variability (reproducibility) is comparable for the Volhard method with filtration and the potentiometric methods, but the direct Volhard method is inferior. Because of its generality and simplicity, the potentiometric method has been adopted official first action; the Volhard method with filtration has been reinstated official final action as an alternative.
