Adjuvant chemotherapy for adenocarcinoma arising from intraductal papillary mucinous neoplasia: multicentre ADENO-IPMN study

BACKGROUND

The clinical impact of adjuvant chemotherapy after resection for adenocarcinoma arising from intraductal papillary mucinous neoplasia is unclear. The aim of this study was to identify factors related to receipt of adjuvant chemotherapy and its impact on recurrence and survival.

METHODS

This was a multicentre retrospective study of patients undergoing pancreatic resection for adenocarcinoma arising from intraductal papillary mucinous neoplasia between January 2010 and December 2020 at 18 centres. Recurrence and survival outcomes for patients who did and did not receive adjuvant chemotherapy were compared using propensity score matching.

RESULTS

Of 459 patients who underwent pancreatic resection, 275 (59.9%) received adjuvant chemotherapy (gemcitabine 51.3%, gemcitabine-capecitabine 21.8%, FOLFIRINOX 8.0%, other 18.9%). Median follow-up was 78 months. The overall recurrence rate was 45.5% and the median time to recurrence was 33 months. In univariable analysis in the matched cohort, adjuvant chemotherapy was not associated with reduced overall (P = 0.713), locoregional (P = 0.283) or systemic (P = 0.592) recurrence, disease-free survival (P = 0.284) or overall survival (P = 0.455). Adjuvant chemotherapy was not associated with reduced site-specific recurrence. In multivariable analysis, there was no association between adjuvant chemotherapy and overall recurrence (HR 0.89, 95% c.i. 0.57 to 1.40), disease-free survival (HR 0.86, 0.59 to 1.30) or overall survival (HR 0.77, 0.50 to 1.20). Adjuvant chemotherapy was not associated with reduced recurrence in any high-risk subgroup (for example, lymph node-positive, higher AJCC stage, poor differentiation). No particular chemotherapy regimen resulted in superior outcomes.

CONCLUSION

Chemotherapy following resection of adenocarcinoma arising from intraductal papillary mucinous neoplasia does not appear to influence recurrence rates, recurrence patterns or survival.

Long-term Outcomes following Resection of Adenocarcinoma Arising from Intraductal Papillary Mucinous Neoplasm (A-IPMN) versus Pancreatic Ductal Adenocarcinoma (PDAC): A Propensity-score Matched Analysis

OBJECTIVE

The aim of the present study was to compare long-term post-resection oncological outcomes between A-IPMN and PDAC.

SUMMARY BACKGROUND DATA

Knowledge of long term oncological outcomes (e.g recurrence and survival data) comparing between adenocarcinoma arising from intraductal papillary mucinous neoplasms (A-IPMN) and pancreatic ductal adenocarcinoma (PDAC) is scarce.

METHODS

Patients undergoing pancreatic resection (2010-2020) for A-IPMN were identified retrospectively from 18 academic pancreatic centres and compared with PDAC patients from the same time-period. Propensity-score matching (PSM) was performed and survival and recurrence were compared between A-IPMN and PDAC.

RESULTS

459 A-IPMN patients (median age,70; M:F,250:209) were compared with 476 PDAC patients (median age,69; M:F,262:214). A-IPMN patients had lower T-stage, lymphovascular invasion (51.4%vs. 75.6%), perineural invasion (55.8%vs. 71.2%), lymph node positivity (47.3vs. 72.3%) and R1 resection (38.6%vs. 56.3%) compared to PDAC(P<0.001). The median survival and time-to-recurrence for A-IPMN versus PDAC were 39.0 versus19.5months (P<0.001) and 33.1 versus 14.8months (P<0.001), respectively (median follow-up,78 vs.73 months). Ten-year overall survival for A-IPMN was 34.6%(27/78) and PDAC was 9%(6/67). A-IPMN had higher rates of peritoneal (23.0 vs. 9.1%, P<0.001) and lung recurrence (27.8% vs. 15.6%, P<0.001) but lower rates of locoregional recurrence (39.7% vs. 57.8%; P<0.001). Matched analysis demonstrated inferior overall survival (P=0.005), inferior disease-free survival (P=0.003) and higher locoregional recurrence (P<0.001) in PDAC compared to A-IPMN but no significant difference in systemic recurrence rates (P=0.695).

CONCLUSIONS

PDACs have inferior survival and higher recurrence rates compared to A-IPMN in matched cohorts. Locoregional recurrence is higher in PDAC but systemic recurrence rates are comparable and constituted by their own distinctive site-specific recurrence patterns.

Comparison of in-gel and in-solution proteolysis in the proteome profiling of organ perfusion solutions

PURPOSE

The organ perfusion solution (perfusate), collected at clinically and temporally significant stages of the organ preservation and transplantation process, provides a valuable insight into the biological status of an organ over time and prior to reperfusion (transplantation) in the recipient. The objective of this study was to assess two bottom-up proteomics workflows for the extraction of tryptic peptides from the perfusate.

EXPERIMENTAL DESIGN

Two different kinds of perfusate samples from kidney and liver trials were profiled using liquid chromatography-mass spectrometry (LC-MS/MS). The preparation of clean peptide mixtures for downstream analysis was performed considering different aspects of sample preparation; protein estimation, enrichment, in-gel and urea-based in-solution digestion.

RESULTS

In-solution digestion of perfusate allowed identification of the highest number of peptides and proteins with greater sequence coverage and higher confidence data in kidney and liver perfusate. Key pathways identified by gene ontology analysis included complement, coagulation and antioxidant pathways, and a number of biomarkers previously linked to ischemia-reperfusion injury were also observed in perfusate.

CONCLUSIONS

This study showed that in-solution digestion is a more efficient method for LC-MS/MS analysis of kidney and liver organ perfusion solutions. This method is also quicker and easier than in-gel digestion, allowing for greater sample throughput, with fewer opportunities for experimental error or peptide loss.

Risk of Recurrence after Surgical Resection for Adenocarcinoma Arising from Intraductal Papillary Mucinous Neoplasia (IPMN) with Patterns of Distribution and Treatment: An International, Multicentre, Observational Study

OBJECTIVE

This international multicentre cohort study aims to identify recurrence patterns and treatment of first and second recurrence in a large cohort of patients after pancreatic resection for adenocarcinoma arising from IPMN.

SUMMARY BACKGROUND DATA

Recurrence patterns and treatment of recurrence post resection of adenocarcinoma arising from IPMN are poorly explored.

METHOD

Patients undergoing pancreatic resection for adenocarcinoma from IPMN between January 2010 to December 2020 at 18 pancreatic centres were identified. Survival analysis was performed by the Kaplan-Meier log rank test and multivariable logistic regression by Cox-Proportional Hazards modelling. Endpoints were recurrence (time-to, location, and pattern of recurrence) and survival (overall survival and adjusted for treatment provided).

RESULTS

Four hundred and fifty-nine patients were included (median, 70 y; IQR, 64-76; male, 54 percent) with a median follow-up of 26.3 months (IQR, 13.0-48.1 mo). Recurrence occurred in 209 patients (45.5 percent; median time to recurrence, 32.8 months, early recurrence [within 1 y], 23.2 percent). Eighty-three (18.1 percent) patients experienced a local regional recurrence and 164 (35.7 percent) patients experienced distant recurrence. Adjuvant chemotherapy was not associated with reduction in recurrence (HR 1.09;P=0.669) One hundred and twenty patients with recurrence received further treatment. The median survival with and without additional treatment was 27.0 and 14.6 months (P<0.001), with no significant difference between treatment modalities. There was no significant difference in survival between location of recurrence (P=0.401).

CONCLUSION

Recurrence after pancreatic resection for adenocarcinoma arising from IPMN is frequent with a quarter of patients recurring within 12 months. Treatment of recurrence is associated with improved overall survival and should be considered.

The safety of telemedicine clinics as an alternative to in-person preoperative assessment for elective laparoscopic cholecystectomy in patients with benign gallbladder disease: a retrospective cohort study

BACKGROUND

The telemedicine clinic for follow up after minor surgical procedures in general surgery is now ubiquitously considered a standard of care. However, this method of consultation is not the mainstay for preoperative assessment and counselling of patients for common surgical procedures such as laparoscopic cholecystectomy. The aim of this study was to evaluate the safety of assessing and counselling patients in the telemedicine clinic without a physical encounter for laparoscopic cholecystectomy.

METHODS

We conducted a retrospective analysis of patients who were booked for laparoscopic cholecystectomy for benign gallbladder disease via general surgery telemedicine clinics from March 2020 to November 2021. The primary outcome was the cancellation rate on the day of surgery. The secondary outcomes were complication and readmission rates, with Clavein-Dindo grade III or greater deemed clinically significant. We performed a subgroup analysis on the cases cancelled on the day of surgery in an attempt to identify key reasons for cancellation following virtual clinic assessment.

RESULTS

We identified 206 cases booked for laparoscopic cholecystectomy from telemedicine clinics. 7% of patients had a cancellation on the day of surgery. Only one such cancellation was deemed avoidable as it may have been prevented by a face-to-face assessment. Severe postoperative adverse events (equal to or greater than Clavien-Dindo grade III) were observed in 1% of patients, and required re-intervention. 30-day readmission rate was 11%.

CONCLUSIONS

Our series showed that it is safe and feasible to assess and counsel patients for laparoscopic cholecystectomy remotely with a minimal cancellation rate on the day of operation. Further work is needed to understand the effect of remote consultations on patient satisfaction, its environmental impact, and possible benefits to healthcare economics to support its routine use in general surgery.

HPB P54 General surgery telemedicine clinics: here to stay post-pandemic?

Background

The telemedicine clinic in general surgery has become widespread since the onset of the COVID-19 pandemic and has remained so following relaxation of restrictions on conventional face-to-face appointments. However, there has been significant scepticism regarding its continued utility. In particular, there is a concern that patients cannot be adequately assessed and counselled for invasive procedures, which may result in high cancellation rates on the day of procedure. The aim of this study was to assess the cancellation rate on the day of surgery for procedures booked in telemedicine clinics.

Methods

We conducted a retrospective analysis of surgical procedures booked via hepatopancreatobiliary (HPB) and general surgery telemedicine clinics from March 2020 to November 2021. From September 2020 onwards, telemedicine clinics were only run for laparoscopic cholecystectomies for benign gallbladder disease. The primary outcome was the cancellation rate of surgical cases booked from telemedicine clinics. Statistical analysis was done using JASP 0.16.2 software.

Results

We identified 240 cases booked for surgery from telemedicine clinic. 162 patients (68%) were female; the median age of the study population was 51 (16–81). 186 (78%) patients had gallstones, 19 (8%) gallbladder polyps, 13 (5%) secondary liver tumour, 5 (2%) liver cyst, 5 (2%) pancreatic tumour, 4 (1.7%) primary liver tumour, 2 (0.8%) gallbladder tumour and 6 (2.5%) other pathologies. 225 patients (94%) underwent surgery on their first admission. Procedures included 192 cholecystectomies, 10 open segmental liver resections, 6 laparoscopic segmental liver resections, 4 distal pancreatectomies, 3 open right hepatectomies, 2 Whipple procedures, 2 laparoscopic deroofing of the liver cyst, 2 laparoscopic lymph node biopsy, 1 extended right hepatectomy, 1 left hepatectomy, 1 small bowel resection and 1 exploratory laparotomy. 15 (6%) patients had surgery cancelled on the day of surgery, 14 of those were for laparoscopic cholecystectomy, 1 for laparoscopic liver resection. Only one such cancellation was deemed avoidable as it may have been prevented by a face-to-face assessment. The majority 212 (88%) of patients were ASA class 1–2; only 28 (12%) were ASA class 3. There was no significant association between high ASA (3) and cancellation rate (Chi square test 5% vs 14% p=0.062).

Conclusions

Telemedicine clinic in general surgery was often the only option to assess and plan operative management for newly referred patients during the COVID-19 pandemic. Our series showed that it was feasible to assess and counsel patients on the phone even for major HPB procedures with a minimal cancellation rate on the day of operation.

SP3.2.3 The open abdomen is associated with increased morbidity and mortality after emergency laparotomy: a retrospective cohort study

Aims

The open abdomen following emergency laparotomy for peritoneal contamination is becoming an increasingly popular method of managing severe intra-abdominal sepsis. However, this approach has been associated with increased morbidity and mortality. The aim of this study is to compare patient populations and post-operative outcomes from patients undergoing primary closure or those managed with an open abdomen after emergency laparotomy.

Methods

A retrospective case note review was undertaken of all patients recorded on the NELA database over a five-year period at a district general hospital. Patients with no intra-abdominal contamination or who were palliated peri-operatively were excluded. Data collected included P-possum morbidity and mortality, post-operative complications (Clavien-Dindo), length of stay and in-hospital mortality.

Results

811 NELA entries were reviewed; 313 were included with 79% (n = 248) undergoing primary closure. Cohorts were similar in age and sex. P-possum morbidity and mortality scores were significantly higher in the open abdomen group (89% vs 79%, p = 0.0003; 38% vs 24%, p = 0.0003, respectively). Of the outcome variables, significant complications (34% vs 11%, p = 0.001), length of stay (31 vs 18 days, p = 0.0001) and mortality (11% vs 4%, p = 0.001) were significantly higher in the open compared to closed abdomen group. Only 10% of patients undergoing primary closure required further surgery.

Conclusions

This study highlights that the open abdomen is used in higher risk patients, with significantly poorer outcomes. This approach, which confers a significant physiological burden requiring further intervention should be used with caution in selected cases.

Using Artificial Intelligence for Predicting Survival of Individual Grafts in Liver Transplantation: A Systematic Review

The demand for liver transplantation far outstrips the supply of deceased donor organs, and so, listing and allocation decisions aim to maximize utility. Most existing methods for predicting transplant outcomes use basic methods, such as regression modeling, but newer artificial intelligence (AI) techniques have the potential to improve predictive accuracy. The aim was to perform a systematic review of studies predicting graft outcomes following deceased donor liver transplantation using AI techniques and to compare these findings to linear regression and standard predictive modeling: donor risk index (DRI), Model for End-Stage Liver Disease (MELD), and Survival Outcome Following Liver Transplantation (SOFT). After reviewing available article databases, a total of 52 articles were reviewed for inclusion. Of these articles, 9 met the inclusion criteria, which reported outcomes from 18,771 liver transplants. Artificial neural networks (ANNs) were the most commonly used methodology, being reported in 7 studies. Only 2 studies directly compared machine learning (ML) techniques to liver scoring modalities (i.e., DRI, SOFT, and balance of risk [BAR]). Both studies showed better prediction of individual organ survival with the optimal ANN model, reporting an area under the receiver operating characteristic curve (AUROC) 0.82 compared with BAR (0.62) and SOFT (0.57), and the other ANN model gave an AUC ROC of 0.84 compared with a DRI (0.68) and SOFT (0.64). AI techniques can provide high accuracy in predicting graft survival based on donors and recipient variables. When compared with the standard techniques, AI methods are dynamic and are able to be trained and validated within every population. However, the high accuracy of AI may come at a cost of losing explainability (to patients and clinicians) on how the technology works.

High Prevalence of Malnutrition among Elderly Veterans in Home Based Primary Care

INTRODUCTION

Elderly Veterans enrolled in VA Home Based Primary Care (HBPC) programs suffer from many diseases including malnutrition. Nutrition screening tools exist in the VA system but they are inconsistently utilized across ambulatory care programs and are neither research validated nor comparable with non-VA populations. The Mini-Nutritional Assessment short-form (MNA-SF) has been validated in international studies in a variety of settings. The primary aim of this study was to find the prevalence of malnutrition among Veterans enrolled in HBPC programs. The secondary objective was to determine the feasibility of adopting a validated nutrition screening tool (Mini-Nutritional Assessment short-form (MNA-SF)).

METHODS

2252 veterans age 65 and older from 18 HBPC programs from across the country participated in the study. The study period was between April and September 2012. WinPepi (version 11.25) was used for descriptive analysis.

RESULTS

We found that the prevalence of malnutrition was 15% (344/2252) and the prevalence of at risk for malnutrition was 40.3% (909/2252).

DISCUSSION

The MNA-SF is an efficient nutrition screening tool and it can be successfully used for the elderly veterans. The prevalence of malnutrition among veterans was high compared to the community dwelling U.S. civilian elderly population. By preventing and treating malnutrition, health care systems should be able to reduce overall health care costs.

Delayed graft function is a syndrome rather than a diagnosis

OBJECTIVES

Delayed graft function is a significant prognostic indicator after renal transplantation. We hypothesized that delayed graft function is not a single entity, and different patterns of delayed graft function reflect various underlying pathological processes.

MATERIALS AND METHODS

An analysis of 762 renal transplants was performed, showing serum creatinine was charted serially for the first 30 days after transplant. Measurements were obtained: time on hemodialysis; time to peak creatinine; time for creatinine to half; time for creatinine to within 10% of baseline.

RESULTS

Four patterns of delayed graft function were identified. There was no association between pattern of delayed graft function, and 1-year graft survival or serum creatinine at 1 year. Time for creatinine to > 15 days was associated with a higher creatinine level at 1 year than it was with patients with time for creatinine to half < 5 days (300.6 ± 54.3 vs 211.3 ± 26.0 μmol/L; P < .01). Patients with 1-year creatinine concentrations > 180 μmol/L had longer time on hemodialysis and time for creatinine to half than did those with 1-year creatinine concentrations ≤ 180 μmol/L (9.2 ± 1.3 μmol/L vs 7.0 ± 0.7 μmol/L; P = .03; and 11.6 ± 1.7 μmol/L vs 6.0 ± 0.4 μmol/L; P < .001). Time for creatinine to half of 6.5 days (sensitivity 67.3%; specificity 79.4%; area under the curve, 0.70) was the best predictor of a 1-year creatinine concentration ≤ 180 μmol/L.

CONCLUSIONS

Delayed graft function is not a single entity; rather; it is the most common presentation of a heterogeneous variety of pathologies. Its rate of resolution of renal function is the best predictor of long-term graft outcome.

Bortezomib-induced peripheral neurotoxicity in human multiple myeloma-bearing mice

The proteasome inhibitor bortezomib is an antineoplastic drug mainly used for the treatment of multiple myeloma (MM). Despite its effectiveness, bortezomib clinical use is often limited by the onset of peripheral neuropathy (BiPN). To better understand the mechanisms of BiPN several rat and mice models have been proposed, but no studies in MM-bearing animals allowing to test the antitumor activity of the selected schedules and the role of MM by itself in peripheral nervous system damage have been reported to date. Here, we carried out a study using immunodeficient C.B-17/Prkdcscid (SCID) mice injected with RPMI8266 human MM cells and treated with bortezomib 1 mg/kg once a week for five weeks. Animals were assessed with neurophysiological, behavioral and pathological methods and tumor volume measurement was performed along the study. At the end of the study BiPN was evident in bortezomib-treated animals, and this neurotoxic effect was evident using a schedule able to effectively prevent tumor growth. However, neurophysiological and pathological evidence of MM induced peripheral nervous system damage was also reported. This model based on MM-bearing animals is more reliable in the reproduction of the clinical setting and it is, therefore, more suitable than the previously reported models of BiPN to study its pathogenesis. Moreover, it represents an optimal model to test the efficacy of neuroprotective agents and at the same time their non-interference with bortezomib antineoplastic activity.

Contemporary outcomes of open repair of thoracoabdominal aortic aneurysm in young patients

Background

Endovascular technology now permits total endovascular thoracoabdominal aortic aneurysm (TAAA) repair with high volume centres reporting encouraging results. The long-term durability of such stent grafts is unknown, leading to concerns regarding their use in younger patients. This study reports contemporary outcomes of open repair in young patients.

Methods

Outcomes for patients age 60 or younger undergoing open TAAA repair between June 1999 and August 2013 with prospective collected data were analysed retrospectively.

Results

Thirty-seven patients (31 men, 84%) with a median age of 56 (range 22–60) were identified with a median TAAA diameter of 6.9 cm (range 5.6-11). Aneurysm aetiology included degenerative change (18), dilation of chronic dissection (10), connective tissue disease (7) and mycotic degeneration (2). Crawford Type IV TAAA were most commonly treated (17), followed by Type II (10), Type III (7) and Type I (3). Two (5%) patients died in hospital, one from multiple organ failure and one from respiratory failure. Three patients (8%) developed temporary paraplegia, all of whom made a complete recovery and 4 (11%) patients required temporary renal replacement therapy. Median critical care stay was 5 days (range 2–28) with an in-hospital stay of 14 days (range 7–83). During a median follow-up of 72 months (range 13–171), no patient subsequently required any further aneurysm related surgical or radiological intervention. The mean (SEM) survival time was 138.5 (11) months. The 5 year survival was 79.7% (8.3) including early deaths, with no aneurysm related complications.

Conclusions

The outcome of open TAAA repair in patients aged less than 60 years is favorable. It is against these results that evolving endovascular interventions must be compared.

The effect of Photon Activation Therapy on cisplatin pre-treated human tumour cell lines: comparison with conventional X-ray irradiation

Cisplatin is an antineoplastic drug widely used for the treatment of several solid tumours. However, the side effects related to cisplatin-based anticancer therapy often outweigh the benefits. Therefore, the identification of new anticancer strategies able to offer a better toxicity profile while maintaining the same level of efficacy as platinum-based treatments would be highly desirable. We assessed the efficacy of synchrotron radiation in triggering the Auger effect in human A549 non-small cell lung cancer and IGROV-1 ovarian cancer cells pre-treated with cisplatin. Cisplatin was chosen as the carrier of platinum atoms in the cells because of its alkylating-like activity and the irradiation was done with monochromatic beams above and below the platinum K-shell edge (78.39 keV). On cisplatin-treated cells, at concentrations allowing 80 percent of cell survival with respect to controls, no differences were observed in cell viability when they were irradiated either above or below the K-shell edge of platinum, suggesting that cisplatin toxicity can mask the enhancement of cell death induced by the irradiation. At lower cisplatin concentrations allowing 95-90 percent of cell survival, an enhancement in cellular death with respect to conventional irradiation conditions was clearly observed in all cancer types when cells were irradiated with beams either above or below the platinum K-shell edge. Our results lend additional support to the suggestion that the Photon Activation Therapy in combination with cisplatin treatment should be further explored in relevant in vivo models of glioma and non-glioma cancer models.

The role of glutamate in diabetic and in chemotherapy induced peripheral neuropathies and its regulation by glutamate carboxypeptidase II

Glutamate has been implicated in the pathogenesis of several diseases on the central nervous system, but recent studies have also suggested that it can be involved also in the onset and course of peripheral neuropathies. Given the increasing evidence of this possibility, several attempts have been performed in order to modulate its activity. Among them, glutamate carboxypeptidase II (GCP II) inhibition demonstrated promising results in different models of peripheral nerve damage, including diabetic and toxic neuropathies.

Drug transporters in chemotherapy induced peripheral neurotoxicity: current knowledge and clinical implications

Several antineoplastic drugs induce severe and dose-limiting peripheral neurotoxicity that can significantly affect the quality of life of cancer patients and cause chronic discomfort. Despite extensive investigation, the fine mechanisms of this side-effect remain unclear. It has recently been suggested that several classes of drug transporters are involved in the genesis of chemotherapy induced peripheral neurotoxicity. Furthermore, the differential distribution and activity of these transporters could also explain the higher sensitivity of the peripheral rather than central nervous system tissues to the toxic action of the anticancer agents. These observations may have important therapeutic implications. In fact, the characterization of the proteins that mediate significant transport of clinically relevant drugs in the nervous system, and the understanding of their changes in the different pathological conditions are important in order to elucidate pathogenetic mechanisms and to identify new potential therapeutic targets so as to limit the severity of chemotherapy-induced peripheral neurotoxicity. This review will be focused on the most recent research progress on the role of drug transporters in chemotherapy-induced peripheral neurotoxicity, and we will discuss the possibility of targeting these transporters as a new and interesting potential strategy for the treatment of the neurotoxic side-effects of antineoplastic drugs.

Third cranial nerve palsy? Look for a sicca syndrome

Sjogren's syndrome (SS) is a systemic autoimmune disorder, and neurological involvement may frequently occur. Here we describe a 79-year-old woman who came to our attention for a sudden right incomplete 3rd cranial nerve palsy. Following extensive investigations, a diagnosis of primary SS was reached, and the patient recovered after treatment with ev Ig and steroids. Therefore, we suggest that SS should be considered in apparently idiopathic 3rd cranial nerve palsies, since, with the appropriate treatment, they might be transient and reversible.

Unequal access and unmet need: neurotic disorders and the use of primary care services

In this paper we use data from the National Survey of Psychiatric Morbidity to examine how many people with neurotic disorders receive professional evaluation, and how this is affected by clinical and sociodemographic differences. We hypothesized that psychiatric symptoms and attendant dysfunctions would both have an effect on contacting, and that key demographic variables would not. The household component of the British National Surveys of Psychiatric Morbidity was based on a random sample of >10,000 subjects. Lay interviewers using the CIS-R established psychiatric symptoms and ICD-10 diagnosis. Social dysfunction was tapped by asking about difficulties in performing seven types of everyday activity. We examined symptom score, ADL deficit score, and demographic variables in relation to contact with primary care physicians for psychiatric symptoms. The major determinant of contacting a primary care physician was severity, mainly due to the level of psychiatric symptoms, but with an independent contribution from social dysfunction. There were also significant contributions from sex, marital status, age, employment status, and whether the subject had a physical condition as well. The major influence on whether people seek the help of their family doctors for mental health problems is the severity of disorder. Although there are some social inequalities in access to family doctors, these are less important. The most salient finding from our study is that even people suffering from high levels of psychiatric symptoms very often do not have contact with professionals who might help them.

Neurotic disorders and the receipt of psychiatric treatment

Access to psychiatric treatment by people with neurotic disorders in the general population is likely to be affected both by the severity of disorder and by sociodemographic differences. In the household component of the National Surveys of Psychiatric Morbidity >10,000 subjects in Great Britain with psychiatric symptoms were interviewed using the CIS-R. They were also asked about difficulties experienced in performing seven types of everyday activity. All subjects classed as having an ICD-10 disorder were questioned about their experience of treatment with antidepressants, hypnotics, and counselling or psychotherapy. Less than 14% of people with current neurotic disorders were receiving treatment for them. Within the previous year, only a third had made contact with their primary care physician for their mental problem: of these <30% were receiving treatment. Overall, 9% of people with disorders were given medication and 8% counselling or psychotherapy. A diagnosis of depressive episode was that most associated with antidepressant medication. Treatment access was affected by employment status, marital status, and age, but the major determinant was symptom severity. Neither sex nor social class influenced which people received treatment. People with psychiatric disorders seldom receive treatment, even when they have consulted their primary care physician about them. In many cases, this must represent unmet needs with a strong claim on health resources. There are also inequalities in the receipt of treatment, although the major influence is the severity of disorder.

Psychiatric disorder and dysfunction in the UK National Survey of Psychiatric Morbidity

BACKGROUND

Psychiatric symptoms are wide-spread in the general population, but have little effect on performance. Deficits in performance and psychiatric symptoms may be the end point of processes common to both, or they may be caused by quite different factors. In this paper we examine the epidemiological distribution of psychiatric symptoms and performance deficits, as indicated by difficulties in activities of daily living (ADL). We hypothesised that ADL difficulties are partly independent of psychiatric symptoms, and that this is reflected in a different demographic distribution.

METHOD

The household component of the National Surveys of Psychiatric Morbidity was based on a sample of around ten thousand subjects selected at random from the population of Great Britain. Psychiatric symptoms were elicited by lay interviewers using the revised Clinical Interview Schedule. Performance was assessed by asking about difficulties experienced in performing seven types of everyday activity. In this paper, our chosen variables were overall symptom and ADL deficit scores, and these were related to standard demographic variables.

RESULTS

There were significant differences in the epidemiological distribution of psychiatric symptoms and ADL difficulties. In particular, men experienced more ADL difficulties at a given symptom level than women. There were also differences in relation to social class, employment status, marital status, ethnic group and age.

CONCLUSIONS

ADL deficits and psychiatric symptoms are related in the general population, and this probably represents common factors in their origin. However, discrepancies in the social distribution of these phenomena suggest there are also aetiological differences. These do not appear to be the result of the impact of physical illness on activities of daily living. Our results emphasise that ADL difficulties should be studied separately, particularly in investigations of treatment seeking.
