Risk factors and incidence of postoperative delirium in elderly patients after elective and emergency surgery.

This study evaluated the incidence of postoperative delirium (POD) in elderly patients undergoing general surgery, the risk factors associated with POD, and its impact on hospital stay and mortality.

Pain prevalence and predictors among inpatients in a major Italian teaching hospital. A baseline survey towards a pain free hospital.

Pain prevalence among inpatients is an important indicator of quality care; it may reach over 80% in various clinical settings. A cross‐sectional survey was conducted in a teaching hospital to depict benchmark data regarding pain prevalence and predictors among the entire inpatient population. Overall 892 patients, ≥6 years old and hospitalized for at least 24 h in 57 hospital wards were interviewed using an internationally applied questionnaire. Patients self‐reported their pain intensity at the time of the interview (T0) and worst pain perceived during the previous 24 h (T‐1), using a numerical rating scale (NRS) and indicated current pain duration. Specific pain predictor data (hospital stay, gender, age and marital status) were obtained from patient medical charts. Pain prevalence at T0 was 38% and 52% at T‐1. Pain was moderate to severe (NRS ≥ 4) in 25% of the patients at T0 and in 40% at T‐1. High pain prevalence was found (at T0 and T‐1, respectively) in Radiotherapy (63%;77%), Obstetrics (68%;54%), and Surgery (59%;45%) wards. Gender was a prominent determinant as pain was significantly associated with females. Pain prevalence was high among young adults or divorced/separated individuals and low among pediatric patients (20%). Protracted hospitalization and prolonged pain duration were associated with major pain severity. Results yield Quality Assurance interventions to ameliorate pain undertreatment. Predictor analysis suggests that attention should be paid to pain management in young adults, socially vulnerable patients and those with protracted hospitalization and pain.

Categories of congruence between inpatient self-reported pain and nurses evaluation

Objective: To enhance the awareness that biased pain estimation may undermine its treatment, we sought to determine the congruence categories (CCs) between inpatient self‐reported pain (PSRP) and nurse pain‐evaluation (NEP) and to look for associations between CCs and inpatient and situational moderators.

Effectiveness and efficiency of intensive care medicine: variable costs in different diagnosis groups.

Background:  To establish the effectiveness of ICU treatment and the efficiency in the use of resources in patients stratified according to 10 diagnosis and two levels‐of‐care. To propose strategies aimed at reducing costs and improving efficiency in each patient group.

Cost-effectiveness analysis of polymyxin-B immobilized fiber column and conventional medical therapy in the management of abdominal septic shock in Italy.

Introduction: Severe abdominal sepsis and septic shock are common problems in intensive care units (ICUs), and carry high mortality. The purpose of this economic analysis was to determine the cost-effectiveness of polymyxin B immobilized fiber column (PMX-F) plus conventional therapy (CT) (PMX-F-CT) versus CT alone for patients with severe sepsis/septic shock of abdominal origin, in the perspective of the Italian hospital. Methods: This was a retrospective cost-effectiveness analysis (CEA) based on data of clinical efficacy and consumption of resources collected alongside an Italian randomized clinical trial. 64 patients were enrolled following emergency surgery for intra-abdominal infection in 10 tertiary care ICUs from December 2004 to December 2007. Direct medical costs analyzed in the study included the consumption of hospital days, ICU days, catecholamine treatment days, renal replacement therapy days, mechanical ventilation treatment days, and the use of the PMX-F device. Resources were valued using published 2010 tariffs and market values. All-cause hospital mortality was extrapolated to survival as expected life years (LY) per patient/arm: for each survivor, average age-gender-related years of life expectancy were retrieved from national life tables; for deceased patients, only the number of CRF reported survival days was retained. Baseline expected years of survival were weighed by the severity of sepsis, according to individual Acute Physiology and Chronic Health Evaluation (Apache) II scores, showing that age/disease severity were comparable in the two groups before treatment initiation. Life expectancy per patient in each treatment group was thus calculated as the combination of life expectancy from Italian National Statistics Institute life tables and intra-hospital mortality detected in the Early Use of Polymyxin B Hemoperfusion in Abdominal Septic Shock (EUPHAS) study. After all costs and 3% discounted survival years were calculated per patient per treatment arm, the incremental CEA was run to obtain the incremental cost-effectiveness ratio (ICER). Univariate sensitivity analyses and 2,000 bootstrap replications were run to test the robustness of the study results. Results: Based on the expected survival years (mean discounted PMX-F-CT 9.37 LY/patient, CT 4.92 LY/patient; difference for PMX-F-CT 4.45 LY/patient; mean undiscounted PMX-F-CT 13.92 LY/patient, CT 7.19 LY/patient; difference +6.73 LY/patient), and the expected mean cost (PMX-F-CT mean 59,922 EUR/patient, CT mean 42,712 EUR/patient; difference for PMX-F-CT 17,211 EUR/patient), the mean ICER for PMX- F-CT resulted in 3,864 EUR/life year gained (LYG; ICER 2,558/undiscounted LYG). Results of the base-case CEA were confirmed by all sensitivity analyses, with ICER values always well below commonly accepted value thresholds. Conclusion: PMX-F-CT versus CT is a cost-effective intervention for treatment of severe sepsis/septic shock of abdominal origin and could be considered for use in the Italian National Health System hospital setting.

Increasing appropriateness of hospital admissions in the Emilia-Romagna region of Italy

Objectives: The Emilia-Romagna region of Italy has reduced the number of available hospital beds and introduced financial incentives to curb hospital use. The goal of this study was to assess the impact of these policies on changes over time in the number of acute hospital admissions classified in diagnosis related groups (DRGs) that could be treated safely and effectively in alternative, less costly settings. Methods: The assessment of the appropriate site of care was based on analysis of hospital discharge data for all hospitals for the selected diagnosis related groups in the Emilia-Romagna region for 2001 to 2005. The necessity for acute hospital admission was based on the severity of a patients principal diagnosis, co-morbid diseases and, for surgical admissions, procedure performed. Results: From 2001 to 2005, potentially inappropriate medical admissions of more than one day decreased from 20,076 to 11,580, a 42% decrease. Inappropriate admissions decreased in both public and private hospitals but there remained a higher rate of inappropriate admissions to private hospitals. Potentially inappropriate medical admissions accounted for 128,319 bed-days in 2001 and 68,968 bed-days in 2005, a reduction of 59,351 bed-days. Potentially inappropriate surgical admissions decreased from 7383 in 2001 to 4349 in 2005, a 41% decrease. Bed-days consumed by inappropriate surgical admissions decreased from 23,181 in 2001 to 13,660 in 2005. Conclusions: The Emilia-Romagna region has succeeded in reducing the use of acute hospital beds for patients in selected diagnosis related groups. However, there are still substantial numbers of admissions that could potentially be treated in less costly settings.

Pain Management in Peripheral Arterial Obstructive Disease: Oral Slow-Release Oxycodone Versus Epidural l-Bupivacaine

OBJECTIVES To compare the effectiveness of oral slow-release oxycodone (group OX, n=18) with that of epidural l-bupivacaine (group LRA, n=13) for the control of moderate/severe pain of advanced-stage peripheral arterial obstructive disease (PAOD) patients. DESIGN Observational and retrospective analysis of advanced stage and hospitalised PAOD patients treated for pain management for at least 7 days prior to surgery or discharged from the hospital without surgery. METHODS The outcome measures were pain intensity using the visual analogue scale under static, (VASs) and dynamic (VASd) conditions; vital signs, treatment side effects and patient satisfaction. RESULTS In both groups, pain control was satisfactory and VAS scores median were VASs<3 and VASd<4; under dynamic conditions, pain control was better in the LRA group (p<0.01). Against few and transient side effects, most patients (n=30) found both pain treatments good or excellent. Results should be confirmed by studies with larger samples. CONCLUSIONS In the perioperative setting, the epidural infusion of local anaesthetics, such as l-bupivacaine, is an effective technique for pain control in PAOD patients; for patients with contraindication for this technique or for non-surgical or outpatients, slow-release oxycodone is suggested as a possible alternative for the control of severe pain in these patients.

Peri-Operative Risk Management in Patients with Alzheimer's Disease

The aim of this review is to identify an evidence-based perioperative management for patients affected by Alzheimers disease (AD) that are scheduled to undergo surgery. This will minimize the negative effects of anesthesia and postoperative sedation and correct those perioperative variables possibly responsible for a decline in cognitive status and a worsening of AD. We here gather evidence on the importance of correct preoperative assessment regarding cognitive and functional status and the presence of preoperative delirium. The potential role of anesthesia, surgery, and postoperative analgosedation as risk factors for development of delirium are herein outlined. Finally, pain assessment instruments, as well as principles of management strategies for postoperative delirium in subjects with AD, are suggested.

The role of open abdomen in non-trauma patient: WSES Consensus Paper

The open abdomen (OA) is defined as intentional decision to leave the fascial edges of the abdomen un-approximated after laparotomy (laparostomy). The abdominal contents are potentially exposed and therefore must be protected with a temporary coverage, which is referred to as temporal abdominal closure (TAC). OA use remains widely debated with many specific details deserving detailed assessment and clarification. To date, in patients with intra-abdominal emergencies, the OA has not been formally endorsed for routine utilization; although, utilization is seemingly increasing. Therefore, the World Society of Emergency Surgery (WSES), Abdominal Compartment Society (WSACS) and the Donegal Research Academy united a worldwide group of experts in an international consensus conference to review and thereafter propose the basis for evidence-directed utilization of OA management in non-trauma emergency surgery and critically ill patients. In addition to utilization recommendations, questions with insufficient evidence urgently requiring future study were identified.

Opioid titration with sustained-release oxycodone and immediate-release morphine for moderate/severe cancer pain: A pilot assessment of the CoDem protocol

OBJECTIVES Opioid titration is the first challenging stage for rapid control of moderate/severe cancer pain. Evidence shows that sustained-release formulations may be used for opioid titration. We set a pilot assessment of the efficacy and tolerability of our in-house protocol (continuous and on demand opioids [CoDem]) of the association of sustained-release oxycodone and immediate-release morphine as rescue dose for opioid titration/rotation in opioid-naïve (NAOP, n = 13), tolerant to weak (WOP, n = 20), or strong opioids (STOP, n = 44) in-patients with moderate/severe cancer pain. METHODS Observational and retrospective analysis of cancer in-patients treated for ≥7 days with the CoDem protocol. OUTCOME MEASURES Pain intensity (patients self-reported pain with numerical rating scale [NRS] under static [NRSs] and dynamic [NRSd] conditions), amount of drug consumption, opioid adverse effects, and patient satisfaction. EFFICACY ENDPOINTS In more than 50 percent of the patients and in <72 hours, steady NRSs and NRSd score reduction of at least two points, NRSs ≤ 3 and NRSd ≤4; and mean daily morphine consumption < mean of one rescue dose and t1:t6 ratio of mean oxycodone daily dose < 1:2. RESULTS Endpoints were reached within 24 hours both within the sample and subgroups. Only NAOP patients reached NRSd ≤ 4 endpoint within 48 hours. Against moderate and transient adverse effects, most patients (84.4 percent) found pain treatment to be good or excellent. CONCLUSIONS The CoDem protocol was shown to be effective and reasonably tolerated for titration for moderate/severe cancer pain relief in both opioid-naïve or opioid-tolerant cancer in-patients. This pilot assessment warrants prospective and comparative studies with larger samples for more generalized results.
