Reduction in length of stay for patients undergoing oesophageal and gastric resections with implementation of enhanced recovery packages

Introduction

The high mortality and morbidity associated with resection for oesophagogastric malignancy has resulted in a conservative approach to the postoperative management of this patient group. In August 2009 we introduced an enhanced recovery after surgery (ERAS) pathway tailored to patients undergoing resection for oesophagogastric malignancy. We aimed to assess the impact of this change in practice on standard clinical outcomes.

Methods

Two cohorts were studied of patients undergoing resection for oesophagogastric malignancy before (August 2008 – July 2009) and after (August 2009 – July 2010) the implementation of the ERAS pathway. Data were collected on demographics, interventions, length of stay, morbidity and in-hospital mortality.

Results

There were 53 and 55 oesophagogastric resections undertaken respectively for malignant disease in each of the study periods. The median length of stay for both gastric and oesophageal resection decreased from 15 to 11 days (Mann– Whitney U, p<0.001) following implementation of the ERAS pathway. There was no significant increase in morbidity (gastric resection 23.1% vs 5.3% and oesophageal resection 25.9% vs 16.7%) or mortality (gastric resection no deaths and oesophageal resection 1.8% vs 3.6%) associated with the changes. There was a significant decrease in the number of oral contrast studies used following oesophageal resection, with a reduction from 21 (77.8%) in 2008–2009 to 6 (16.7%) in 2009–2010 (chi-squared test, p<0.0001).

Conclusions

The introduction of an enhanced recovery programme following oesophagogastric surgery resulted in a significant decrease in length of median patient stay in hospital without a significant increase in associated morbidity and mortality.     

Developmental changes in group climate in two types of group therapy for binge-eating disorder: A growth curve analysis

Abstract

The development of group climate across 16 sessions of group psychodynamic–interpersonal psychotherapy (GPIP) and group cognitive–behavioral therapy (GCBT) for 65 female treatment completers with binge-eating disorder (BED) was assessed. Engaged scale growth for GPIP patients varied across sessions and was best represented by a cubic growth curve. This suggested that GPIP progressed in definable phases that reflected a rupture and repair sequence of engaged group climate. For patients receiving GCBT, engaged, avoiding, and conflict scale growth was gradual and consistent (i.e., linear), indicating an increase in positive group climate across sessions. This likely reflected patients taking greater responsibility for treatment as suggested by the CBT model. Linear growth in engaged climate mediated the relationship between attachment anxiety and outcome in GPIP. A consistent increase in engaged group climate through the rupture and repair phase may be a necessary condition for successful treatment of BED patients with high attachment anxiety who receive GPIP.

Zusammenfassung

Entwicklung von Veränderungen im Gruppenklima bei zwei Arten von Gruppentherapie für Essstörungen: Eine Wachstumskurven-Analyse

Es wurde die Entwicklung des Gruppenklimaklimas über 16 Sitzungen bei psychodynamisch - interpersoneller Gruppentherapie (psychodynamic-interpersonal psychotherapy [GPIP]) und kognitiv-verhaltensmässiger Gruppentherapie (group cognitive-behavioral therapy [GCBT]) eingeschätzt. An der Untersuchung nahmen 65 Frauen mit Essanfallstörungen, die die Behandlung auch zu Ende geführt haben, teil. Der Zuwachs der Engagement-Skala variierte für GPIP-Patienten und ließ sich am besten mit Hilfe einer kubischen Wachstumskurve wiedergeben. Das legt für das engagierte Gruppenklima das Fortschreiten vom GPIP-Patienten mit einer Phasensequenz von Einbrüchen und ihrer Wiederherstellung nahe. Für GCBT-Patienten war der Anstieg der Skalen für engagiertes, vermeidendes und konflikthaftes Gruppenklima graduell und konsistent (d. h. linear) und wies insgesamt auf einen kontinuierlichen Anstieg des positiven Gruppenklimas über die Sitzungen hin. Das spiegelt wahrscheinlich die größere Verantwortung der Patienten für die Behandlung, wie sie nach dem CBT-Modell angenommen wird, wider. Ein linearer Anstieg des engagierten Gruppenklimas, über die Phasen von Einbrüchen und Wiederherstellung hinweg, könnte eine notwendige Bedingung für eine erfolgreiche Behandlung von Essanfallstörungs-Patienten mit hoher Bindungsangst unter der GPIP Bedingung sein.

Résumé

Changements du climat dans le groupe dans deux types de thérapies de groupe pour le binge-eating?: une analyse par courbe de croissance

Le développement du climat dans le groupe était évalué à travers 16 séances de psychothérapie de groupe psychodynamique–interpersonnelle (GCBT) et de thérapie de groupe cognitivo–comportementale (GCBT) pour 65 femmes avec un trouble de binge–eating (BED) ayant terminé le traitement. La croissance sur l’échelle d'engagement des patients en GPIP variait à travers les séances et était le mieux représentée par une courbe de croissance cubique. Ceci suggère que la GPIP progressait par phases définies reflétant une séquence de rupture et de réparation du climat d'engagement du groupe. Pour les patients en GCBT, la croissance des échelles d'engagement, d’évitement et de conflit était graduel et consistant (linéaire), indiquant une augmentation du climat de groupe positif à travers les séances. Ceci pourrait refléter une plus grande prise de responsabilité par les patients pour leur traitement, comme suggéré par le modèle CBT. La croissance linéaire du climat engagé était médiatrice de la relation entre l'anxiété d'attachement et l'issue en GPIP. Une augmentation consistante du climat d'engagement dans le groupe dans la phase de rupture et de réparation pourrait être une condition nécessaire pour un traitement réussi de patients BED avec une haute anxiété d'attachement qui bénéficient d'une GPIP.

Resumen

Cambios en el clima grupal en dos tipos de terapia para la bulimia: análisis de la curva de crecimiento

Se evaluó el desarrollo del clima grupal a lo largo de 16 sesiones de una psicoterapia grupal psicodinámica-interpersonal (GPIP) y de otra grupal cognitivo-comportamental (GCBT) de sesenta y cinco mujeres que completaron su tratamiento para desorden bulímico (BED). El crecimiento de la escala comprometida para pacientes GPIP varió a través de las sesiones y se lo representó mejor por medio de una curva de crecimiento cúbico. Esto sugiere que la GPIP progresó en fases definibles que reflejaron una secuencia de ruptura y reparación del clima comprometido grupal. Para los pacientes que recibieron GCBT, el crecimiento en las escalas comprometida, evitativa y conflictiva fue gradual y consistente (esto es, lineal), lo que indica un aumento en el clima positivo grupal a lo largo de las sesiones. Probablemente, esto fue reflejo de que los pacientes tomaron su tratamiento con mayor responsabilidad, según lo sugiere el modelo CBT. Un crecimiento lineal en el clima comprometido medió entre la ansiedad de apego y el resultado en GPIP. Un aumento consistente en el clima grupal comprometido a través de las fases de ruptura y reparación puede ser una condición necesaria para un tratamiento exitoso con GPIP de pacientes BED con gran ansiedad de apego.

Resumo

Mudanças no ambiente de grupo em dois tipos de terapia de grupo para a perturbação de ingestão alimentar compulsiva: uma análise da curva de crescimento

Foi avaliado o desenvolvimento de atmosfera de grupo durante 16 sessões de psicoterapia interpessoal psicodinâmica de grupo (PIPG) e terapia cognitivo-comportamental de grupo (TCCG) no tratamento de 65 mulheres que completaram o tratamento para a perturbação de ingestão alimentar compulsiva (PIAC). O aumento na escala do envolvimento em pacientes com PIPG variou ao longo das sessões e era melhor descrito por uma curva de crescimento cúbica. Isto sugere que a PIPG progrediu em fases definidas que reflectem a ruptura e restauram a sequência da atmosfera de envolvimento do grupo. Para os pacientes que receberam TCCG, a elevação nas escalas de envolvimento, evitamento e conflito foi gradual e consistente (i.e. linear), indicando um aumento positivo no ambiente do grupo ao longo das sessões. Isto parece reflectir que os pacientes tomam maiores responsabilidades no tratamento tal como é sugerido no modelo cognitivo-comportamental. O crescimento linear no envolvimento mediava a relação entre a vinculação ansiosa e o resultado da PIPG. Um aumento consistente no envolvimento do ambiente de grupo ao longo da ruptura e fase de reconciliação poderá ser necessário para o sucesso no tratamento de pacientes com BED, com elevada vinculação ansiosa, que recebem PIPG.

Sommario

Cambiamenti nel clima di gruppo in due tipi di terapia di gruppo per il binge-eating disorder: un'analisi della curva crescente

E’ stato valutato lo sviluppo del clima di gruppo mediante 16 sedute di psicoterapia di gruppo psicodinamico-interpersonale (GPIP) e di terapia di gruppo cognitivo-comportamentale (GCBT) per 65 donne con binge-eating disorder (BED) che hanno terminato il trattamento.

La crescita nelle scale impiegate per i pazienti GPIP è variata tra le sedute ed è stata al meglio rappresentata da una curva di crescita cubica. Ciò ha suggerito che il GPIP è progredito in fasi determinabili che hanno riflettuto una sequenza di rottura e riparazione del clima di gruppo instaurato.

Per i pazienti che hanno ricevuto la GCBT, la crescita nelle scale di adesione, evitamento e conflitto è stata graduale e consistente (lineare), indicando un incremento nel positivo clima di gruppo attraverso le sedute. Ciò probabilmente ha rispecchiato i pazienti che hanno assunto la maggiore responsabilità per il trattamento, come suggerito dal modello CBT.

La crescita lineare nel clima instaurato ha mediato la relazione tra ansia d'attaccamento ed esito nel GPIP. Un incremento consistente nel clima di gruppo instaurato attraverso la fase di rottura e riparazione potrebbe essere una condizione necessaria per un trattamento di successo dei pazienti con BED con alta ansia d'attaccamento che ricevono GPIP.

     

Population pharmacokinetics of valganciclovir prophylaxis in paediatric and adult solid organ transplant recipients

Aim

Our aims were to quantify ganciclovir pharmacokinetics in paediatric and adult kidney, liver and lung transplant patients taking a range of valganciclovir doses to prevent herpes virus infections, including a 450 mg regimen, and to identify sources of pharmacokinetic variability.

Method

Plasma samples were collected at 2, 4, 8 and 12 weeks post-transplant and at 4, 6, 8 and 12 months post-transplant in subjects prescribed longer courses. Ganciclovir was measured by liquid chromatography/ultraviolet detection. Non-linear mixed effects modelling was used to analyze the concentration–time data and evaluate demographic and transplant-related covariates.

Results

A two compartment model with first order absorption best described the data. Given the range of body sizes, clearance and volume of distribution terms were scaled using standard weight-based allometric exponents. Creatinine clearance was included on apparent oral clearance. Final estimates in a standard 70 kg individual for apparent oral clearance, central volume of distribution, intercompartmental clearance and peripheral volume of distribution were 14.5 l h⁻¹, 87.5 l, 4.80 l h⁻¹ and 42.6 l, respectively. The median terminal half-life for kidney, liver and lung transplant recipients was 9.4, 9.5 and 8.2 h, respectively. Median exposure (i.e. AUC(0,∞) in subjects taking valganciclovir 900 mg or 450 mg once daily was 57.4 and 34.3 μg ml⁻¹ h, respectively.

Conclusion

Allometric scaling allowed simultaneous analysis of data from children and adults. Ganciclovir pharmacokinetics were similar among kidney, liver and lung transplant recipients. Ganciclovir exposure after valganciclovir 450 mg once daily may be suboptimal in some individuals and requires evaluation along with virologic outcomes data.
